[0002] In construction, concrete feeding devices arrange pump pipes along tower cranes and tower crane booms, utilizing the height of the tower crane and the free rotation of the tower crane boom to achieve high-level concrete pouring operations. However, in existing pouring operations, when the tower crane boom slides up and down along the tower crane, it is necessary to frequently replace pump pipes of corresponding lengths to adapt to different pouring operation heights, resulting in a large workload for disassembling and assembling pump pipes and poor adaptability.

[0031] The present invention has the following advantages:

[0032] 1. The pump tube of the present invention has a flexible shell suitable for pumping materials, and the flexible shell can be flexibly extended or shortened to adjust the length of the pump tube, so that the pump tube can meet the use of different pumping distances, eliminating the need for frequent replacement of pump tubes of different lengths and reducing the workload of disassembly and assembly. The support spring is embedded in the interlayer of the flexible shell to expand the flexible shell, facilitating material transportation. The support spring can be stretched with the extension of the flexible shell and compressed with the shortening of the flexible shell. The telescopic outer liner can extend and retract with the extension and retraction of the flexible shell, and the telescopic outer liner protects the outer periphery of the flexible shell and assists in shaping the flexible shell and improving structural strength. Therefore, the pump tube of the present invention is formed by the cooperation of the support spring, the flexible shell, and the telescopic outer liner to form an adjustable length pump tube, which takes into account both flexibility and structural strength, meets diverse usage needs, and has good adaptability.

[0033] 2. In the pump feed tube of the present invention, the supporting spring includes a left-handed spring and a right-handed spring, both of which are embedded in the interlayer of the flexible tube shell. This arrangement, with the left-handed and right-handed springs arranged simultaneously, can balance the rotational internal stress of the springs within the flexible tube shell, preventing the flexible tube shell from twisting after the internal stress is released during use, and enhancing the deformation resistance of the flexible tube shell.

[0034] 3. The pump feed pipe of the present invention further includes a dense wire mesh, which is sleeved on the outer periphery of the supporting spring and located within the interlayer of the flexible tube shell, or the dense wire mesh is sleeved between the flexible tube shell and the telescopic outer liner. The dense wire mesh can further improve the pressure resistance of the flexible tube shell, thereby reducing the risk of deformation of the flexible tube shell due to excessive pumping pressure.

[0035] 4. The pump feed pipe of the present invention includes a telescopic outer liner comprising multiple pipe sections that are sequentially slidably connected. When the flexible shell extends, the multiple pipe sections slide away from each other to stretch the telescopic outer liner; when the flexible shell shortens, the multiple pipe sections slide close together to shorten the telescopic outer liner. Therefore, the length of the telescopic outer liner can be adaptively adjusted according to the extension or shortening of the flexible shell, thus providing protection for flexible shells of different lengths and exhibiting strong adaptability.

[0036] 5. The pump feed pipe of the present invention includes a pipe ring and a conical tile. The pipe ring is provided with an annular mounting groove. The narrow end of the conical tile is slidably disposed in the annular mounting groove. Multiple conical tiles are provided and are arranged in annular overlapping arrangement along the annular mounting groove. Adjacent conical tiles can slide relative to each other along the circumference of the pipe ring to adjust the diameter of the pipe section. In the above configuration, when the flexible shell extends, multiple pipe sections slide away from each other, causing the telescopic outer liner to lengthen. Simultaneously, adjacent conical tiles slide away from each other along the circumference of the pipe ring to increase the diameter of the pipe sections. This increases the material conveying space within the flexible shell, slowing down the material pumping speed and reducing the pumping pressure on the flexible shell, thus lowering the risk of rupture due to excessive pumping pressure. When the flexible shell shortens, multiple pipe sections slide closer together, causing the telescopic outer liner to shorten. Simultaneously, adjacent conical tiles slide closer together along the circumference of the pipe ring to reduce the diameter of the pipe sections, increasing the material pumping speed within the flexible shell and improving construction efficiency. Furthermore, the overlapping of multiple conical tiles increases the thickness of the pipe sections, thereby enhancing the pressure-bearing capacity of the flexible shell. Therefore, the diameter of the telescopic outer liner can also change accordingly with the length of the telescopic outer liner to adjust the overall pressure-bearing capacity of the flexible shell and the telescopic outer liner, meeting the needs of different working conditions.

[0037] 6. In the pump feed pipe of the present invention, the outer wall of the conical tile is provided with a sliding groove along the length direction, and the inner wall of the conical tile is provided with a sliding pin. Between adjacent pipe sections, the sliding pin on the conical tile of one pipe section slides into the sliding groove on the conical tile of another pipe section. With this arrangement, when the flexible pipe shell expands and contracts, and multiple pipe sections slide relative to each other, the sliding pin on the conical tile of one pipe section slides within the sliding groove on the conical tile of another pipe section, thereby causing the telescopic outer liner to expand and contract along the length direction, achieving extension or shortening. Furthermore, the cooperation between the sliding pin and the sliding groove can guide the sliding of the pipe section and improve the accuracy of the sliding.

[0038] 7. In the pump feed pipe of the present invention, the outer wall of the conical tile is provided with a radial groove along the radial direction of the pipe section, and the inner wall of the conical tile is provided with a radial locking pin. Between adjacent conical tiles in the same pipe section, the radial locking pin on one conical tile slides into the radial groove on another conical tile. With this arrangement, when the flexible pipe shell expands and contracts, and multiple conical tiles slide relative to each other radially, the radial locking pin on one of the adjacent conical tiles slides in the radial groove on another conical tile, thereby causing the telescopic outer liner to expand and contract radially, realizing the increase or decrease of diameter. Furthermore, the cooperation of the radial locking pin and the radial groove can also guide the radial sliding of the conical tile and improve the sliding accuracy.

[0039] 8. The pumping device of the present invention includes the pumping tube of the present invention. The pumping tube of the pumping device is formed by the cooperation of a supporting spring, a flexible tube shell and a telescopic outer liner to form a pumping tube with adjustable length, which takes into account both flexibility and structural strength, and meets diverse application requirements.

[0040] 9. The pumping device of the present invention includes a vertical pumping pipe and a horizontal pumping pipe. The pumping device also includes a tower, which includes a tower column and a boom. The boom is slidably connected to the tower column. The bottom of the vertical pumping pipe is the inlet end, and the top of the vertical pumping pipe is connected to the horizontal pumping pipe. The horizontal pumping pipe is arranged along the length of the boom and is slidably connected to the boom. The end of the horizontal pumping pipe away from the vertical pumping pipe is the outlet end. With this configuration, material enters the vertical pumping pipe from the inlet end, then flows through the vertical pumping pipe into the horizontal pumping pipe, and finally exits from the outlet end for high-altitude pouring operations. By sliding the boom along the tower column, the horizontal pumping pipe can be moved to different heights, while simultaneously causing the vertical pumping pipe to extend and retract adaptively, thereby adjusting the pouring height of the pumping device. The horizontal pumping pipe, arranged along the length of the boom and slidably connected to the boom, allows for control of different pouring positions through the extension and retraction of the horizontal pumping pipe along the boom length, providing high flexibility.

[0041] 10. The pumping device of the present invention further includes a sliding support mechanism, which is connected to the telescopic outer liner of the transverse pumping pipe and is slidably connected to the boom. This arrangement allows the sliding support mechanism to slide on the boom as the transverse pumping pipe extends or retracts along the length of the boom, thereby providing sliding support for the transverse pumping pipe and transmitting force to the boom, thus improving sliding stability.

[0042] 11. The pumping device of the present invention includes a sliding support mechanism comprising a snap-fit ​​ring and a sliding seat. The snap-fit ​​ring is sleeved on the outer periphery of the telescopic outer liner, and the sliding seat is connected to the snap-fit ​​ring and slidably connected to the boom. The snap-fit ​​ring snaps and fixes the telescopic outer liner, and the sliding seat supports and connects to the snap-fit ​​ring. When the telescopic outer liner extends or retracts, it drives the sliding seat to slide along the boom to achieve length adjustment of the telescopic outer liner.

[0043] 12. In the pumping device of the present invention, the locking ring is a U-shaped ring with an arc-shaped bottom for locking and fitting the telescopic outer liner. Connecting arms are formed on both sides of the U-shaped ring and are fixedly connected to the sliding seat. The sliding seat is a U-shaped seat with rotatable sliding wheels on both sides, which roll along the boom. When the U-shaped seat slides under the drive of the transverse pumping pipe, the sliding wheels on both sides of the U-shaped seat rotate along the boom, thereby converting the sliding friction between the sliding seat and the boom into rolling friction. This reduces the telescopic resistance of the transverse pumping pipe and lowers the difficulty of adjusting the length of the transverse pumping pipe.

[0044] 13. The pumping device of the present invention further includes a guide support mechanism, which includes a vertical support column and a pump pipe support frame. The vertical support column is arranged along the tower column, and the pump pipe support frame is connected to the vertical pumping pipe. The pump pipe support frame is slidably connected to the vertical support column. With this arrangement, when the vertical pumping pipe extends and retracts with the boom, it drives the pump pipe support frame to slide along the vertical support column, thereby providing sliding support for the vertical pumping pipe through the pump pipe support frame and improving sliding stability.

[0045] 14. In the pumping device of the present invention, the guide support mechanism further includes a locking component, which is adapted to lock the fixing ring and the vertical support column. When the vertical pumping pipe is extended or retracted into place, the locking component can lock the fixing ring and the vertical support column, thereby fixing the vertical pumping pipe, preventing it from shaking during material pumping and improving its stability.

[0046] 15. In the pumping device of the present invention, the locking assembly includes a magnetic suction part and an electromagnetic trigger part. The magnetic suction part is continuously arranged along the height direction of the vertical slide groove, and the electromagnetic trigger part is connected to the end of the fixing ring. The electromagnetic trigger part can engage with one of the magnetic suction parts to lock the fixing ring and the vertical support. The locking assembly is configured such that the magnetic suction part and the electromagnetic trigger part engage. When the vertical pump tube extends or retracts to its position, the electromagnetic trigger part is energized and engages with one of the magnetic suction parts. When the vertical pump tube needs to extend or retract, the electromagnetic trigger part is de-energized and disengages from the magnetic suction part, allowing the vertical pump tube to be adjusted in length or retraction.

[0047] 16. In the pumping device of the present invention, the locking assembly further includes a slide block, an elastic element, and a guide pulley. The slide block is slidably disposed within a vertical groove and connected to the end of a fixing ring. An electromagnetic trigger is disposed on the slide block and faces a magnetic attraction part. The elastic element is connected to the slide block and is adapted to be compressed when the electromagnetic trigger and magnetic attraction parts are engaged. The guide pulley is connected to the end of the elastic element away from the slide block and is rotatably disposed on the inner wall of the vertical groove. With this configuration, when the vertical pump tube extends or retracts, the fixing ring, slide block, elastic element, and guide pulley slide together along the vertical groove. Simultaneously, the guide pulley rotates on the inner wall of the vertical groove, thereby converting the sliding friction between the slide block and the inner wall of the vertical groove into rolling friction. This reduces the extension and retraction resistance of the vertical pump tube and lowers the difficulty of adjusting the length of the vertical pump tube. Attached Figure Description

[0059] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0062] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0063] like Figure 1 and Figure 2 As shown, this embodiment discloses a pumping tube, including a flexible tube shell 21, a support spring 22, and a telescopic outer liner 23. The flexible tube shell 21 is suitable for pumping materials, the support spring 22 is embedded in the interlayer of the flexible tube shell 21 to expand the flexible tube shell 21, and the telescopic outer liner 23 is sleeved on the outside of the flexible tube shell 21.

[0064] In this embodiment, the pump tube has a flexible shell 21 suitable for pumping materials. The flexible shell 21 can be flexibly extended or shortened to adjust the length of the pump tube, so that the pump tube can meet the needs of different pumping distances. This eliminates the need for frequent replacement of pump tubes of different lengths, reducing the workload of disassembly and assembly. The support spring 22 is embedded in the interlayer of the flexible shell 21 to expand the flexible shell 21, facilitating material transportation. The support spring 22 can be stretched as the flexible shell 21 extends and compressed as the flexible shell 21 shortens. The telescopic outer liner 23 can extend and retract with the extension and retraction of the flexible shell 21. The telescopic outer liner 23 protects the outer periphery of the flexible shell 21 and assists in shaping the flexible shell 21 and improving its structural strength. Therefore, the pump tube of this embodiment is formed by the cooperation of the support spring 22, the flexible shell 21, and the telescopic outer liner 23 to form an adjustable-length pump tube, which takes into account both flexibility and structural strength, meets diverse usage needs, and has good adaptability.

[0065] The pump feed tube will now be described in detail with reference to the accompanying drawings.

[0066] In this embodiment, the flexible shell 21 can be a cylindrical shell made of at least two layers of waterproof flexible material, with an internal cavity suitable for accommodating the conveyed material to prevent leakage during material conveying. Specifically, the flexible shell 21 can be a corrugated pipe.

[0067] The support spring 22 can be stretched as the flexible tube shell 21 elongates, and it can also be compressed as the flexible tube shell 21 shortens. Specifically, the diameter of the support spring 22 is between the inner and outer diameters of the flexible tube shell 21, so that the support spring 22 can be embedded in the interlayer of the flexible tube shell 21, thereby expanding the flexible tube shell 21 and allowing materials to be conveyed through the inner cavity of the flexible tube shell 21.

[0068] Preferably, the support spring 22 includes a left-handed spring 221 and a right-handed spring 222, both of which are embedded within the flexible tubular shell 21. This arrangement, with the left-handed spring 221 and right-handed spring 222 simultaneously arranged, can balance the rotational internal stress of the flexible tubular shell 21, preventing the flexible tubular shell 21 from twisting after the internal stress is released during use, and enhancing the deformation resistance of the flexible tubular shell 21.

[0069] The pump feed pipe also includes a wire mesh (not shown in the figure), which is sleeved around the outer periphery of the support spring 22 and located within the interlayer of the flexible tube shell 21, or sleeved between the flexible tube shell 21 and the telescopic outer liner 23. The wire mesh further enhances the pressure-bearing capacity of the flexible tube shell 21, thereby reducing the risk of deformation of the flexible tube shell 21 due to excessive pumping pressure. It is understood that the wire mesh can be selectively installed in practical applications depending on the pumping pressure.

[0070] In this embodiment, the telescopic outer liner 23 includes multiple tube sections that are slidably connected in sequence. When the flexible shell 21 extends, the multiple tube sections slide away from each other to stretch the telescopic outer liner 23. When the flexible shell 21 shortens, the multiple tube sections slide close together to shorten the telescopic outer liner 23. Therefore, the length of the telescopic outer liner 23 can be adaptively adjusted according to the extension or shortening of the flexible shell 21 to protect flexible shells 21 of different lengths and has strong adaptability.

[0071] In terms of specific structure, the pipe section includes a pipe ring and a conical tile 231. The pipe ring is provided with an annular mounting groove. The narrow end of the conical tile 231 is slidably disposed in the annular mounting groove. Multiple conical tiles 231 are provided and are arranged in annular overlap along the annular mounting groove. Adjacent conical tiles 231 can slide relative to each other along the circumference of the pipe ring to adjust the diameter of the pipe section.

[0072] The above configuration allows for the following: when the flexible shell 21 extends, multiple pipe sections slide away from each other, causing the telescopic outer liner 23 to extend. Simultaneously, adjacent conical tiles 231 slide away from each other circumferentially along the pipe ring to increase the diameter of the pipe sections. This increases the material conveying space within the flexible shell 21, slowing down the material pumping speed and reducing the pumping pressure on the flexible shell 21, thus lowering the risk of rupture due to excessive pumping pressure. When the flexible shell 21 shortens, multiple pipe sections slide closer together, causing the telescopic outer liner 23 to shorten. When adjacent conical tiles 231 slide close together along the circumference of the pipe ring, the diameter of the pipe section is reduced, the material pumping speed inside the flexible pipe shell 21 is increased, and construction efficiency is improved. At the same time, the overlap of multiple conical tiles 231 can increase the thickness of the pipe section, thereby enhancing the pressure bearing capacity of the flexible pipe shell 21. Therefore, the diameter of the telescopic outer liner 23 in this embodiment can also change accordingly with the change of the length of the telescopic outer liner 23 to adjust the overall pressure bearing capacity of the flexible pipe shell 21 and the telescopic outer liner 23 to meet the usage requirements of different working conditions.

[0073] Further, this can be understood as follows: when the flexible shell 21 elongates, it means the material conveying height increases. With the diameter remaining constant, the pumping pressure that the flexible shell 21 needs to withstand increases. Therefore, the radial sliding of the conical tiles 231 increases the diameter of the pipe section, allowing the diameter of the flexible shell 21 inside the pipe section to increase (the flexible shell 21 itself has extensibility). Since the diameter of the flexible shell 21 is inversely proportional to the material pumping speed, the material pumping speed inside the flexible shell 21 decreases, thereby reducing the pumping pressure borne by the flexible shell 21 and thus reducing the risk of rupture. Conversely, when the flexible shell 21 elongates... The shortening of the flexible shell 21 means a reduction in the material conveying height. With the diameter remaining unchanged, the pumping pressure that the flexible shell 21 needs to withstand is reduced. Therefore, the diameter of the pipe section is reduced by the radial sliding of the conical tiles 231, which reduces the diameter of the flexible shell 21 inside the pipe section (the flexible shell 21 itself has extensibility). This increases the internal material pumping speed and improves construction efficiency. At the same time, the overlapping of the conical tiles 231 can also increase the thickness of the entire telescopic outer liner 23, thereby improving the pressure-bearing capacity of the flexible shell 21 and reducing the risk of the flexible shell 21 breaking due to excessive material pumping speed.

[0074] Specifically, the pipe ring serves to connect multiple conical tiles 231, allowing the multiple conical tiles 231 to slide and overlap in an annular manner to form a whole (i.e., a pipe section). The annular mounting groove is a recess and is set on the lower surface of the pipe ring.

[0075] The narrow end of the conical tile 231 is slidably engaged in the annular mounting groove. There is an overlapping area between adjacent conical tiles 231. Multiple conical tiles 231 can be stacked and arranged in sequence along the annular mounting groove to form a pipe section.

[0076] When multiple conical tiles 231 are fully unfolded, i.e., when the overlapping area of ​​the conical tiles 231 is the smallest, the diameter of the pipe section is the largest. When multiple conical tiles 231 overlap to the maximum extent, i.e., when the overlapping area of ​​the conical tiles 231 is the largest, the diameter of the pipe section is the smallest. This allows the diameter of the pipe section to be adjusted between the maximum and minimum to meet different usage requirements.

[0077] A conical tile 231 can be formed by bending a conical piece into an arc. The conical tile 231 has a narrow end and a wide end. The narrow end is slidably connected in an annular mounting groove, and the wide end is set away from the narrow end. Therefore, a pipe section formed by overlapping multiple conical tiles 231 is also a conical pipe.

[0078] It should be noted that the annular mounting groove has a certain width to facilitate the overlapping arrangement of the conical tiles 231. The number of conical tiles 231 is determined according to the required diameter of the pipe section, and this embodiment does not impose a specific limitation.

[0079] Furthermore, the outer wall of the conical tile 231 is provided with a sliding groove 2311 along its length, and the inner wall of the conical tile 231 is provided with a sliding pin 2312. Between adjacent pipe sections, the sliding pin 2312 on the conical tile 231 of one pipe section slides into the sliding groove 2311 on the conical tile 231 of another pipe section. With this arrangement, when the flexible shell 21 expands and contracts, and multiple pipe sections slide relative to each other, the sliding pin 2312 on the conical tile 231 of one pipe section slides within the sliding groove 2311 on the conical tile 231 of another pipe section, thereby causing the telescopic outer liner 23 to expand and contract along its length, achieving extension or shortening. The cooperation between the sliding pin 2312 and the sliding groove 2311 also guides the sliding of the pipe section and improves the accuracy of the sliding.

[0080] The sliding groove 2311 is a groove opened along the length of the tapered tile 231. Its length limits the sliding distance of the pipe section, and thus limits the telescopic length of the telescopic outer liner 23. The sliding pin 2312 can only slide along the opening direction of the sliding groove 2311, thereby realizing the sliding guide function. At the same time, the cooperation between the sliding pin 2312 and the sliding groove 2311 also serves to connect adjacent pipe sections and prevent them from sliding off.

[0081] In this embodiment, the outer wall of the conical tile 231 is provided with a radial groove 2313 along the radial direction of the pipe section, and the inner wall of the conical tile 231 is provided with a radial locking pin 2314. Between adjacent conical tiles 231 in the same pipe section, the radial locking pin 2314 on one conical tile 231 slides into the radial groove 2313 on another conical tile 231. With this arrangement, when the flexible pipe shell 21 extends and retracts, and multiple conical tiles 231 slide relative to each other in the radial direction, the radial locking pin 2314 on one of the adjacent conical tiles 231 slides in the radial groove 2313 on another conical tile 231, thereby causing the telescopic outer liner 23 to extend and retract in the radial direction, realizing the increase or decrease of diameter. Furthermore, the cooperation between the radial locking pin 2314 and the radial groove 2313 can also guide the radial sliding of the conical tile 231 and improve the sliding accuracy.

[0082] Understandably, the radial groove 2313 is a groove opened along the radial direction of the pipe section. Its length limits the radial sliding distance of the conical tile 231, thereby limiting the adjustable range of the diameter of the telescopic outer liner 23. The radial locking pin 2314 can only slide along the opening direction of the radial groove 2313, thus achieving a sliding guide function. At the same time, the cooperation between the radial locking pin 2314 and the radial groove 2313 also serves to connect adjacent conical tiles 231.

[0083] In terms of specific placement, the sliding groove 2311 is located on one side of the conical tile 231 and on the surface of the conical tile 231 that is always exposed. The radial groove 2313 is located in the middle of the conical tile 231 and can achieve full or partial coverage as the conical tile 231 slides.

[0084] In this embodiment, connecting flanges are provided at both ends of the telescopic outer liner 23 to facilitate the connection of the pump feed pipe with other structures.

[0085] like Figure 1 , Figures 3 to 8 As shown, this embodiment also discloses a pumping device, including the pumping tube of this embodiment. The pumping device of this embodiment has a pumping tube whose length is adjustable, formed by the cooperation of a support spring 22, a flexible tube shell 21, and a telescopic outer liner 23, balancing flexibility and structural strength to meet diverse application requirements.

[0086] In this embodiment, the pumping pipe includes a vertical pumping pipe 2 and a horizontal pumping pipe 3. The pumping device also includes a tower 1, which includes a tower column 11 and a boom 12. The boom 12 is slidably connected to the tower column 11. The bottom of the vertical pumping pipe 2 is the feed end, and the top of the vertical pumping pipe 2 is connected to the horizontal pumping pipe 3. The horizontal pumping pipe 3 is arranged along the length of the boom 12 and is slidably connected to the boom 12. The end of the horizontal pumping pipe 3 away from the vertical pumping pipe 2 is the discharge end.

[0087] In the above configuration, the material enters the vertical pump pipe 2 from the feed end, then is fed into the horizontal pump pipe 3 through the vertical pump pipe 2, and finally outputs from the discharge end for high-altitude pouring operations. By sliding the boom 12 along the tower column 11, the horizontal pump pipe 3 can be moved to different heights, while the vertical pump pipe 2 can be extended and retracted adaptively, thereby adjusting the pouring height of the pumping device. The horizontal pump pipe 3 is arranged along the length of the boom 12 and is slidably connected to the boom 12. The extension and retraction of the horizontal pump pipe 3 along the length of the boom 12 can be used to control different pouring positions, which is highly flexible.

[0088] The structure of the pumping device will now be described in detail with reference to the accompanying drawings.

[0089] In this embodiment, the tower 1 is used to support high-altitude pouring operations, and its bottom is fixed to the foundation. When the boom 12 slides vertically along the tower column 11, it can drive the operator's cab and the horizontal pump pipe 3 to rise and fall together, as well as drive the vertical pump pipe 2 to extend and retract, so as to adjust the pouring operation height.

[0090] The boom 12 and the tower column 11 can be driven by a gear and rack to achieve linear movement of the boom 12 along the tower column 11, or the boom 12 can be driven by a linear hydraulic cylinder to achieve linear movement of the boom 12 along the tower column 11. The specific choice depends on the needs, and this embodiment does not impose any specific limitations.

[0091] This embodiment also includes a sliding support mechanism 4, which is connected to the telescopic outer liner 23 of the transverse pumping pipe 3 and is slidably connected to the boom 12. With this configuration, when the transverse pumping pipe 3 extends or retracts along the length of the boom 12, it drives the sliding support mechanism 4 to slide on the boom 12, thereby providing sliding support for the transverse pumping pipe 3 and transmitting force to the boom 12, thus improving sliding stability.

[0092] Regarding the specific structure of the sliding support mechanism 4, in this embodiment, the sliding support mechanism 4 includes a snap-fit ​​ring 41 and a sliding seat 42. The snap-fit ​​ring 41 is sleeved on the outer periphery of the telescopic outer liner 23, and the sliding seat 42 is connected to the snap-fit ​​ring 41 and slidably connected to the boom 12. The snap-fit ​​ring 41 snaps and fixes the telescopic outer liner 23, and the sliding seat 42 connects and supports the snap-fit ​​ring 41. When the telescopic outer liner 23 extends or retracts, it drives the sliding seat 42 to slide along the boom 12 to achieve length adjustment of the telescopic outer liner 23.

[0093] Specifically, the snap-fit ​​ring 41 is a U-shaped ring with an arc-shaped bottom, used to snap and fit the telescopic outer liner tube 23. Connecting arms are formed on both sides of the U-shaped ring, and these connecting arms are fixedly connected to the sliding seat 42. The sliding seat 42 is a U-shaped seat with rotatable sliding wheels 421 on both sides, which roll along the boom 12. When the U-shaped seat slides under the influence of the transverse pumping pipe 3, the sliding wheels 421 on both sides of the U-shaped seat rotate along the boom 12, thereby converting the sliding friction between the sliding seat 42 and the boom 12 into rolling friction. This reduces the telescopic resistance of the transverse pumping pipe 3 and lowers the difficulty of adjusting the length of the transverse pumping pipe 3.

[0094] Specifically, a sliding rail (not shown in the figure) can be set along the length of the boom 12, and the sliding wheel 421 can be rotatably mounted on the sliding rail.

[0095] As an optional technical solution in this embodiment, the pumping device further includes a guide support mechanism, which includes a vertical support column 5 and a pump pipe support frame 6. The vertical support column 5 is arranged along the tower column 11, and the pump pipe support frame 6 is connected to the vertical pumping pipe 2. The pump pipe support frame 6 is slidably connected to the vertical support column 5. With this arrangement, when the vertical pumping pipe 2 extends and retracts with the boom 12, it drives the pump pipe support frame 6 to slide along the vertical support column 5, thereby providing sliding support for the vertical pumping pipe 2 through the pump pipe support frame 6 and improving sliding stability.

[0096] Specifically, the vertical support column 5 is provided with a vertical sliding groove 51, and the pump pipe support frame 6 includes a fixing ring 61. The fixing ring 61 is sleeved at the pipe section connection of the telescopic outer liner 23, and the end of the fixing ring 61 is slidably disposed in the vertical sliding groove 51. The fixing ring 61 is locked and fixed at the pipe section connection of the telescopic outer liner 23. When the vertical pump material pipe 2 extends or retracts, the end of the fixing ring 61 slides in the vertical sliding groove 51 to provide sliding support for the vertical pump material pipe 2 and improve the smoothness of sliding.

[0097] Specifically, the vertical groove 51 is a T-shaped groove opened along the length of the vertical support column 5. The wider end of the T-shaped groove is located inside the vertical support column 5, and the narrower end of the T-shaped groove is connected to the surface of the vertical support column 5. The end of the fixing ring 61 can extend into the wider end of the T-shaped groove through the narrower end of the T-shaped groove.

[0098] In this embodiment, the shape and structure of the retaining ring 61 are the same as those of the retaining ring 41. For details, please refer to the description of the retaining ring 41 above, which will not be repeated here.

[0099] The guide support mechanism also includes a locking component 62, which is adapted to lock the fixing ring 61 and the vertical support column 5. When the vertical pumping pipe 2 is extended or retracted into place, the locking component 62 can lock the fixing ring 61 and the vertical support column 5, thereby fixing the vertical pumping pipe 2, preventing it from shaking during material pumping and improving its stability.

[0100] In terms of specific structure, the locking assembly 62 includes a magnetic suction part 621 and an electromagnetic trigger part 622. The magnetic suction part 621 is continuously arranged along the height direction of the vertical slide groove 51, and the electromagnetic trigger part 622 is connected to the end of the fixing ring 61. The electromagnetic trigger part 622 can engage with one of the magnetic suction parts 621 to lock the fixing ring 61 and the vertical support 5. The locking assembly 62 is configured such that the magnetic suction part 621 and the electromagnetic trigger part 622 engage. When the vertical pump tube 2 is extended or retracted to its position, the electromagnetic trigger part 622 is energized and engages with one of the magnetic suction parts 621. When the vertical pump tube 2 needs to extend or retract, the electromagnetic trigger part 622 is de-energized and separates from the magnetic suction part 621. At this time, the vertical pump tube 2 can be extended or retracted.

[0101] A magnetic attraction part 621 is disposed on the inner wall of the wider end of the T-shaped groove, and multiple magnetic attraction parts 621 are continuously disposed along the length direction of the T-shaped groove, so that the electromagnetic trigger part 622 can be engaged with the magnetic attraction part 621 and locked when slid to any position. For example, multiple magnetic attraction parts 621 are continuously disposed to form a magnetic attraction strip.

[0102] The electromagnetic triggering part 622 is an electromagnetic device. When energized, it becomes magnetic and can be attracted to the magnetic attraction part 621. When the electromagnetic property is deactivated, it disappears and can be separated from the magnetic attraction part 621. Since the specific structure and principle of the electromagnetic device are existing technologies, they will not be described in detail in this embodiment.

[0103] In terms of quantity, multiple fixing rings 61 are provided, spaced apart along the length of the vertical pump tube 2, to provide uniform support to all parts of the vertical pump tube 2 and achieve force distribution. Each fixing ring 61 has an electromagnetic device on both sides of its connecting arm, and magnetic suction parts 621 are also provided on both sides of the inner wall of the T-shaped groove with the wider end. The fixing ring 61 is locked on both sides by the magnetic attraction between the electromagnetic devices on both sides of the fixing ring 61 and the magnetic suction parts 621 on both sides of the inner wall of the T-shaped groove, which provides good stability.

[0104] In this embodiment, the locking assembly 62 further includes a slide block 623, an elastic element 624, and a guide pulley 625. The slide block 623 is slidably disposed in the vertical groove 51 and connected to the end of the fixing ring 61. The electromagnetic trigger part 622 is disposed on the slide block 623 and is opposite to the magnetic attraction part 621. The elastic element 624 is connected to the slide block 623 and is adapted to be compressed when the electromagnetic trigger part 622 and the magnetic attraction part 621 are attracted. The guide pulley 625 is connected to the end of the elastic element 624 away from the slide block 623 and is rotatably disposed on the inner wall of the vertical groove 51.

[0105] With the above configuration, when the vertical pump tube 2 extends or retracts, it drives the fixing ring 61, the slide block 623, the elastic element 624 and the guide pulley 625 to slide together along the vertical slide groove 51. At the same time, the guide pulley 625 rotates on the inner wall of the vertical slide groove 51, thereby converting the sliding friction between the slide block 623 and the inner wall of the vertical slide groove 51 into rolling friction, thereby reducing the extension and retraction resistance of the vertical pump tube 2 and reducing the difficulty of adjusting the length of the vertical pump tube 2.

[0106] Specifically, the slide block 623 is slidably locked in the wider end of the T-shaped groove. The side of the slide block 623 facing the magnetic suction part 621 is provided with an electromagnetic trigger part 622 and an elastic member 624. The electromagnetic trigger part 622 corresponds to the magnetic suction part 621. The end of the elastic member 624 away from the slide block 623 is provided with a guide pulley 625. The guide pulley 625 makes rolling contact with the inner wall of the wider end of the T-shaped groove. When the electromagnetic trigger 622 is de-energized, the electromagnetic trigger 622 and the magnetic attraction 621 separate under the elastic force of the elastic member 624, so that when the vertical pump tube 2 extends and retracts, it can drive the slide 623 and its electromagnetic trigger 622, elastic member 624 and guide pulley 625 to move together. At the same time, the guide pulley 625 rolls along the inner wall of the T-shaped groove. When the electromagnetic trigger 622 is energized, the electromagnetic trigger 622 and the magnetic attraction 621 attract and compress on the elastic member 624 to lock the entire slide 623 and the fixing ring 61, thereby limiting the position of the vertical pump tube 2.

[0107] Understandably, if the boom 12 needs to slide along the tower column 11, the locking component 62 of the vertical pumping pipe 2 must be unlocked before sliding, that is, the electromagnetic trigger part 622 is de-energized, so that the electromagnetic trigger part 622 is separated from the magnetic attraction part 621, ensuring that the vertical pumping pipe 2 is in a state that can extend and retract vertically. After the boom 12 drives the vertical pumping pipe 2 to rise and fall to the position, the locking component 62 is locked, that is, the electromagnetic trigger part 622 is energized, so that the electromagnetic trigger part 622 is attracted to the magnetic attraction part 621, thereby locking the vertical pumping pipe 2 and the vertical support column 5.

[0108] In this embodiment, the number of sections of the vertical pumping pipe 2 needs to be set according to the height of the tower column 11 so that the telescopic length of the vertical pumping pipe 2 can meet the use of the boom 12 at different heights. During the installation of the vertical pumping pipe 2, a pumping pipe auxiliary hoist arranged at the top of the boom 12 is used to install the vertical pumping pipe 2 section by section to the corresponding position of the tower column 11. After each section of the vertical pumping pipe 2 is installed, the newly installed section of the vertical pumping pipe 2 is connected to the already installed section of the vertical pumping pipe 2, and at the same time, the electromagnetic trigger 622 and the corresponding magnetic suction 621 are controlled to engage to lock the corresponding section of the vertical pumping pipe 2 to the required height. In this way, the vertical pumping pipe 2 is installed and connected into a whole section by section.

[0109] In addition to the above-mentioned configuration, the pumping device of this embodiment also includes a connecting bend 7 and a vertical feeding pipe 8. The connecting bend 7 is connected to both the vertical pumping pipe 2 and the horizontal pumping pipe 3. The connecting bend 7 is connected to the boom 12 via a hanger 71. The vertical feeding pipe 8 is connected to the discharge end of the horizontal pumping pipe 3. The connecting bend 7 serves to connect the vertical pumping pipe 2 and the horizontal pumping pipe 3, so that the material can be smoothly transported between the vertical pumping pipe 2 and the horizontal pumping pipe 3. The connecting bend 7 is connected and supported by the hanger 71, which can transfer the weight of the pipe system to the boom 12 for stress support. The vertical feeding pipe 8 serves as the material discharge pipe, which can ensure the discharge direction.

[0110] Specifically, both ends of the connecting bend 7 are provided with bend flanges. The bend flange at one end of the connecting bend 7 is connected to the connecting flange of the horizontal pump material pipe 3, and the bend flange at the other end of the connecting bend 7 is connected to the connecting flange of the vertical pump material pipe 2, thereby connecting the three into a whole. The flange connection method facilitates disassembly and assembly.

[0111] The vertical feeding pipe 8 is connected to the flange at the end of the horizontal pumping pipe 3 away from the connecting bend 7. The vertical feeding pipe 8 is perpendicular to the horizontal pumping pipe 3 and the discharge direction of the vertical feeding pipe 8 is vertically downward.

[0112] The pumping device also includes a pump pipe traction trolley 9, which is connected to the vertical feeding pipe 8 and is slidably mounted on the boom 12. When the pump pipe traction trolley 9 slides along the boom 12, it can drive the vertical feeding pipe 8 and the transverse pumping pipe 3 connected to it to move, thereby causing the transverse pumping pipe 3 to extend and retract. At the same time, the sliding wheels 421 on both sides of the sliding seat 42 slide along the boom 12, thereby realizing the adjustment of the length of the transverse pumping pipe 3.

[0113] Furthermore, a hook traction trolley 10 is slidably mounted on the boom 12. One of the hook traction trolley 10 and the pump pipe traction trolley 9 is equipped with a magnetic suction device 101, and the other with an electromagnetic chuck 91. The magnetic suction device 101 can engage with the electromagnetic chuck 91. The hook traction trolley 10 is used to drive the hook to slide along the boom 12, thereby adjusting the hook's different working positions. When the electromagnetic chuck 91 is energized, it engages with the magnetic suction device 101 to fix the hook traction trolley 10 and the pump pipe traction trolley 9 into a single unit. At this time, the hook traction trolley 10 and the pump pipe traction trolley 9 can move synchronously, driving the hook to move and / or driving the transverse pump pipe 3 to extend and retract to achieve length adjustment.

[0114] It is understandable that by using the magnetic suction device 101 and the electromagnetic chuck 91 together, the hook traction trolley 10 and the pump pipe traction trolley 9 can be attracted together as a whole. At this time, the two can be controlled and driven by the same drive device. The drive device and the hook traction trolley 10 are connected by transmission to drive the two and simplify the device structure.

[0115] Of course, when only the hook is needed for lifting operations, the horizontal pump pipe 3 is pushed to the root of the boom 12 and folded down (i.e., the horizontal pump pipe 3 is shortened to its shortest length) using the hook traction trolley 10 to make room on the boom 12 and ensure the operating range of the hook traction trolley 10, so that the hook can run on the boom 12 for its entire stroke.

[0116] The pumping device in this embodiment also includes a machine base 30, which is located at the bottom of the tower column 11 to provide stable support for the tower column 11. A parking track is provided below the machine base 30 to facilitate the parking of the feeding mixer truck.

[0117] The tower column 11 is rotatably connected to the machine base 30, so that the rotation of the tower column 11 drives the boom 12 to rotate, which in turn drives the vertical feeding pipe 8 and the hook traction trolley 10 on the boom 12 to rotate, thereby realizing the adjustment of the discharge position and the circumferential position of the hook operation to meet the operation requirements of different positions.

[0118] Furthermore, the pumping device also includes a feed pipe 20, which is mounted on the machine base 30 and connected to both the vertical pumping pipe 2 and the pump. With this configuration, the pump can pump the material through the feed pipe 20 into the vertical pumping pipe 2, and then transport it through the connecting bend 7 and the horizontal pumping pipe 3 to the vertical feeding pipe 8 for discharge, thus realizing the casting operation.

[0119] A feed hopper 201 is provided at the top of the feed pipe 20. The feed hopper 201 is adapted to connect with the connecting flange at the end of the vertical pump feed pipe 2 away from the connecting bend 7. In this embodiment, multiple feed pipes 20 are arranged along the circumference of the machine base 30, and the vertical pump feed pipe 2 can selectively connect with one of the feed pipes 20. With this arrangement, when the vertical pump feed pipe 2 rotates relative to the machine base 30 along with the tower column 11, it can connect with feed pipes 20 at different positions, thereby satisfying the requirement of material conveying at different positions.

[0120] In addition, for the convenience of automated control, this embodiment may also include a controller. The controller is connected to the electromagnetic chuck 91, the electromagnetic trigger 622 and the drive device. The controller controls the sliding and locking of the vertical pump material pipe 2 by controlling the power on and off of the electromagnetic trigger 622, controls the engagement or disengagement of the pump pipe traction trolley 9 and the hook traction trolley 10 by controlling the power on and off of the electromagnetic chuck 91, and controls the movement distance of the pump pipe traction trolley 9 and the hook traction trolley 10 by controlling the opening or closing of the drive device.

[0121] To facilitate understanding of the pumping device in this embodiment, its usage process is described below:

[0122] Material conveying process: The feeding mixer truck conveys the material to the parking track 301. The pump pumps the material through the feed pipe 20 into the vertical pumping pipe 2, and then through the connecting bend pipe 7 and the horizontal pumping pipe 3 to the vertical feeding pipe 8 for discharge, thus realizing the pouring operation.

[0123] When the pouring or hoisting operation height needs to be adjusted, the locking component 62 of the vertical pumping pipe 2 is unlocked, that is, the electromagnetic trigger part 622 is de-energized, so that the electromagnetic trigger part 622 separates from the magnetic attraction part 621, ensuring that the vertical pumping pipe 2 is in a state that can extend and retract vertically. The boom 12 slides along the tower column 11, driving the horizontal pumping pipe 3, the vertical feeding pipe 8, and the hook traction trolley 10 on the boom 12 to rise and fall together, thereby realizing the adjustment of the working height. At the same time, it drives the vertical pumping pipe 2 to adaptively extend and retract, that is, the flexible pipe shell 21 of the vertical pumping pipe 2 flexibly extends and retracts, and multiple pipe sections slide relative to each other to extend or shorten the vertical pumping pipe 2. When the vertical pumping pipe 2 is extended, the adjacent conical tiles 231 inside the pipe section move along the vertical pumping pipe 2. The circumferential sliding of the tube ring increases the diameter of the vertical pump tube 2. When the vertical pump tube 2 shortens, the adjacent conical tiles 231 in the tube section slide close to each other along the circumferential of the tube ring to reduce the diameter of the vertical pump tube 2. During the extension and retraction of the vertical pump tube 2, the guide pulley 625 on the slide block 623 rotates along the inner wall of the vertical slide groove 51 under the force of the elastic element 624 to guide and support the extension and retraction of the vertical pump tube 2. After the boom 12 is raised and lowered to the position, the locking component 62 of the vertical pump tube 2 is locked, that is, the electromagnetic trigger part 622 is energized so that the electromagnetic trigger part 622 and the magnetic attraction part 621 are attracted together, thereby locking the vertical pump tube 2 and the vertical support 5 to ensure the stability of the vertical pump tube 2 in use.

[0124] When the length of the transverse pump feed pipe 3 needs to be adjusted, the hook traction trolley 10 moves close to the pump pipe traction trolley 9, and the electromagnetic chuck 91 is energized, causing the electromagnetic chuck 91 to engage and fix with the magnetic attraction device 101 to form a whole with the hook traction trolley 10 and the pump pipe traction trolley 9. At this time, the hook traction trolley 10 and the pump pipe traction trolley 9 can move synchronously to drive the transverse pump feed pipe 3 to extend or retract, that is, the flexible tube shell 21 of the transverse pump feed pipe 3 flexibly extends and retracts, and multiple tube sections slide relative to each other to allow the transverse pump feed pipe 3 to be lengthened or shortened. When the transverse pump feed pipe 3 is extended, the pipe... The adjacent conical tiles 231 within the section slide away from each other along the circumference of the pipe ring to increase the diameter of the transverse pumping pipe 3. When the transverse pumping pipe 3 shortens, the adjacent conical tiles 231 within the pipe section slide closer to each other along the circumference of the pipe ring to reduce the diameter of the transverse pumping pipe 3. During the extension and retraction of the transverse pumping pipe 3, the sliding wheels 421 on both sides of the sliding seat 42 roll along the boom 12. When the transverse pumping pipe 3 is extended and retracted to its final position, the electromagnetic chuck 91 is de-energized, and the hook pulls the trolley 10 away from the pump pipe and moves the trolley 9, causing the electromagnetic chuck 91 to separate from the magnetic suction device 101.

[0125] When only the hook is needed for lifting operations, the electromagnetic chuck 91 can be attracted and fixed to the magnetic suction device 101 to drive the horizontal pump pipe 3 to shorten to a folded state (shortest position), thereby freeing up space on the boom 12, making it easier for the hook traction trolley 10 to drive the hook for real-time operations.

[0126] When the circumferential position of the pouring or hoisting operation needs to be adjusted, the tower column 11 rotates relative to the machine platform 30, which drives the boom 12 to rotate, and then drives the vertical pumping pipe 2, the horizontal pumping pipe 3, the vertical feeding pipe 8 and the hook traction trolley 10 to rotate, thereby realizing the adjustment of the discharge position and the circumferential position of the hook operation to meet the operation requirements of different positions.

[0127] In this embodiment, the material is concrete or silt or other pouring materials.

[0128] This embodiment also discloses a method of using a pump material pipe, including the following steps: when the flexible tube shell 21 is flexibly stretched and lengthened, it drives the support spring 22 to elastically extend and the telescopic outer liner 23 to extend, so as to increase the overall length of the pump material pipe and extend the material pumping distance; when the flexible tube shell 21 is flexibly shortened, it drives the support spring 22 to elastically contract and the telescopic outer liner 23 to retract, so as to reduce the overall length of the pump material pipe and shorten the material pumping distance.

[0129] The method of using the pump feed pipe in this embodiment has the same technical effect as the pump feed pipe in this embodiment, and will not be described again here.

[0130] This embodiment also discloses an installation method for a pumping device, including the following steps: calculating the total length of the pumping pipe to be installed based on the total pumping distance of the pumping device; installing the pumping pipe segment by segment to the corresponding pumping position, and splicing the segments of the pumping pipe together. The installation method of the pumping device in this embodiment has the same technical effect as the pumping device in this embodiment, and will not be described again here.

[0131] Optionally, the step of calculating the total length of the pumping pipes to be installed based on the total pumping distance of the pumping device includes: calculating the length of the vertical pumping pipe 2 to be installed based on the height of the tower column 11 of the pumping device; and calculating the length of the horizontal pumping pipe 3 to be installed based on the length of the boom 12 of the pumping device. This allows for the determination of the installation lengths of the vertical and horizontal pumping pipes 3 by calculating the corresponding height of the tower column 11 and the length of the boom 12, thus avoiding installation dimensions that do not meet usage requirements.

[0132] Optionally, the pump feed pipe is installed segment by segment to the corresponding pumping position, and the steps for splicing each segment of the pump feed pipe include: after each segment of the pump feed pipe is installed, the newly installed pump feed pipe should be connected to the sequentially installed pump feed pipe at the pipe joint; the installed pump feed pipe is locked to the required height using the locking component 62, and then the next segment of the pump feed pipe is installed, thus completing the installation segment by segment. The segmented installation of the pump feed pipe, and the use of the locking component 62 to lock the installed pump feed pipe to the required height before installing the next segment of the pump feed pipe, achieves stable and efficient installation of the pump feed pipe.

[0133] This invention also provides a control method for a pumping device, comprising the following steps: when the pumping height of the pumping device increases, the pump feed tube is extended; when the pumping height of the pumping device decreases, the pump feed tube is shortened. The control method of the pumping device in this embodiment has the same technical effects as the pumping device in this embodiment, and will not be described again here.

[0134] Optionally, when the pumping height of the pumping device increases, the step of extending the pumping pipe includes: unlocking the locking component 62 to the vertical pumping pipe 2, sliding the boom 12 along the tower column 11 to extend the vertical pumping pipe 2, and sliding the pump pipe support frame 6 along the vertical support column 5 to extend the vertical pumping pipe 2. After reaching the desired position, the locking component 62 locks the vertical pumping pipe 2. And / or, when the pumping height of the pumping device decreases, the step of shortening the pumping pipe includes: unlocking the locking component 62 to the vertical pumping pipe 2, sliding the boom 12 along the tower column 11 to shorten the vertical pumping pipe 2, and sliding the pump pipe support frame 6 along the vertical support column 5 to descend the vertical pumping pipe 2. After descending to the desired position, the locking component 62 locks the vertical pumping pipe 2. The adjustment and fixation of the vertical pumping pipe 2 are achieved by unlocking and locking the locking component 62, resulting in good overall stability.

[0135] Specifically, before raising or lowering the boom 12, the locking assembly 62 of the vertical pumping pipe 2 must be unlocked to ensure that the vertical pumping pipe 2 is in a state where it can extend and retract vertically. During the overall raising and lowering process, the vertical pumping pipe 2 will extend or shorten as the boom 12 rises in elevation, and the corresponding pumping pipe support frame 6 will slide in the vertical slide groove 51. After the raising and lowering is completed, the locking assembly 62 locks and fixes the vertical pumping pipe and its corresponding pumping pipe. Pumping operations can only begin after the entire equipment has been adjusted.

[0136] Optionally, the control method further includes: activating the magnetic suction device 101 to engage the electromagnetic chuck 91, causing the hook traction trolley 10 and the pump pipe traction trolley 9 to be attracted and fixed; using the hook traction trolley 10 to drive the pump pipe traction trolley 9 to slide along the boom 12 toward the tower column 11, thereby moving the transverse pumping pipe 3 to a folded state; activating the magnetic suction device 101 to engage the electromagnetic chuck 91, causing the hook traction trolley 10 and the pump pipe traction trolley 9 to be attracted and fixed; using the hook traction trolley 10 to drive the pump pipe traction trolley 9 to slide along the boom 12 away from the tower column 11, thereby moving the transverse pumping pipe 3 to an extended state for use. The above methods can move the transverse pumping pipe 3 to a folded state, avoiding interference with hoisting operations, and can also move the transverse pumping pipe 3 to an extended state for use, facilitating pumping operations and demonstrating strong adaptability.

[0137] Of course, the above descriptions are the optimal technical solutions for this embodiment. In addition:

[0138] In some embodiments, the hook traction trolley 10 and the pump pipe traction trolley 9 can also be equipped with a drive device for independent control and drive, which can also realize the length adjustment of the transverse pump pipe 3 and the adjustment of the hook position.

[0139] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
