Description

Technical Field

[0001] This invention relates to the field of concrete placing device technology, and in particular to a quick-installation variable amplitude telescopic placing device. Background Technology

[0002] Currently, concrete pump trucks are commonly used to pump concrete during the construction of large foundation slabs. Although pump trucks offer greater flexibility in concrete placement, their deployment requires extending hydraulic outriggers, which occupies a large area of ​​space and limits the number of pump trucks that can be deployed simultaneously, thus restricting the pouring speed of the large foundation slabs.

[0003] A chute is a traditional concrete conveying device that relies on the downward flow of concrete to greatly increase the placement speed. Compared to the placement method of a pump truck, the chute is more cost-effective. However, traditional chutes have disadvantages such as difficulty in installation, inconvenience in relocation, and a fixed placement range due to their fixed installation and the need for stable and reliable mounting points.

[0004] Therefore, there is a need to provide a quick-installation variable-amplitude telescopic fabric distribution device that can solve the problems of limited simultaneous deployment by the pump truck and inconvenience in chute relocation in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-installation variable-amplitude telescopic fabric distribution device that can solve the problems of limited simultaneous feeding capacity of truck pumps and inconvenience of chute relocation in the prior art.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0010] In the primary standard fabric placement device, the fabric placement pump pipe includes several sections of standard pump pipe body, which are connected end to end in sequence to form a primary pumping pipeline; the upper end of the primary pumping pipeline is connected to the pump pipe section of the luffing pump pipe, and the lower end of the primary pumping pipeline extends to the top of the hopper of the secondary telescopic luffing fabric placement device.

[0011] In the secondary telescopic luffing fabric placing device, the fabric placing pump pipe includes a telescopic track pump pipe, a telescopic large pump pipe, and a telescopic adjustment component. The upper end of the telescopic track pump pipe is connected to the pump pipe section of the luffing pump pipe. A telescopic track is formed on the telescopic track pump pipe, and a track guide wheel matching the telescopic track is installed on the telescopic large pump pipe, so that the telescopic large pump pipe can be telescopically connected to the telescopic track pump pipe. The telescopic adjustment component is installed on the slewing arm and the luffing pump pipe of the secondary telescopic luffing fabric placing device and is connected to the telescopic large pump pipe, so that the lower end of the telescopic large pump pipe can extend to the pouring position or over obstacles.

[0012] The telescopic adjustment assembly includes an electric hoist, a basket hook, a wire rope, a wire rope guide wheel assembly, and a pulley assembly. The electric hoist is mounted on the slewing arm, and one end of the wire rope is connected to the luffing pump pipe via the basket hook. At least one set of wire rope guide wheel assemblies is installed on the pump pipe section of the luffing pump pipe, and several sets of wire rope guide wheel assemblies are installed at intervals on the outer wall of the telescopic pump pipe. The pulley assembly is installed on the outer wall of the telescopic pump pipe and is located between several sets of wire rope guide wheel assemblies, so that the other end of the wire rope passes through each set of wire rope guide wheel assemblies in sequence and is then connected to the pulley assembly.

[0013] The building's fixing components include a trestle plate and a support beam, and the clamping assembly includes a first clamping assembly clamped on the trestle plate and a second clamping assembly clamped on the support beam.

[0014] The first clamping assembly includes several clamping units arranged on both sides of the hopper. Each clamping unit includes a vertical plate, an adjusting track, a first fixed plate, a clamping plate, adjusting track wheels, connecting bolts, and a clamping hook plate. The vertical plate is fixedly installed on the outer wall of the hopper. One end of the adjusting track is vertically fixed to the vertical plate. The first fixed plate is fixedly installed on the top of the adjusting track, and the clamping plate is fixedly installed on the bottom of the adjusting track. The two sets of adjusting track wheels are slidably arranged on the adjusting track. Several connecting bolts are spaced apart on the top of the two sets of adjusting track wheels and fixedly connected to the upper end of the clamping hook plate. Several oblong holes are formed on the first fixed plate, and several connecting bolts pass through several oblong holes respectively. The bottom of the clamping hook plate has an L-shaped structure, so that the horizontal section of the L-shaped structure of the clamping plate and the clamping hook plate are clamped on the top and bottom surfaces of the trestle plate respectively.

[0015] The second clamping assembly includes a second fixed plate, a support rail, a hopper support foot, outriggers, a spiral push rod, rollers, a hopper support plate, and an operating platform.

The operating platform is installed on the hopper support foot.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention features a primary standard concrete placing device and a secondary telescopic luffing concrete placing device. The primary standard concrete placing device can be mounted on a trestle plate via a first clamping component, and the secondary telescopic luffing concrete placing device can be mounted on a support beam via a second clamping component. Concrete is transported from the pump truck on the trestle plate to the primary standard concrete placing device, which then transports the concrete to the secondary telescopic luffing concrete placing device, which in turn transports the concrete to the pouring location, thus completing the concrete placing and pouring operations. This solves the problem of large space occupation by pump trucks in existing technologies, which prevents large-scale concrete delivery. Furthermore, the convenient assembly and disassembly of the first and second clamping components solves the problem of inconvenient chute relocation in existing technologies, thereby improving the efficiency of pouring large foundation slabs and other similar projects.

[0018] 2. Due to the first clamping component and the second clamping component, the first clamping component clamps the material onto the trestle plate through multiple symmetrically arranged clamping units on both sides of the hopper, which can adapt to trestle plates of different thicknesses. The second clamping component clamps the material onto both sides of the support beam through a pair of second fixing plates and multiple hopper support plates, which can adapt to support beams of different widths. It can simultaneously ensure the ease of disassembly and assembly and the secure installation of the primary standard fabric placing device and the secondary telescopic luffing fabric placing device. At the same time, the primary standard fabric placing device and the secondary telescopic luffing fabric placing device can be flexibly combined with the first clamping component and the second clamping component according to actual installation needs, which has higher adaptability and flexibility for different installation scenarios.

[0019] 3. This invention features a rotating assembly, a standard pump pipe body, a telescopic track pump pipe, and a telescopic large pump pipe. The rotating assembly can be used to adjust the direction and angle of concrete delivery by the standard pump pipe body, the telescopic track pump pipe, and the telescopic large pump pipe, thereby ensuring that the concrete placement meets the requirements of the pouring construction, improving construction efficiency while ensuring construction quality. At the same time, the standard pump pipe body can be flexibly spliced ​​according to the actual placement distance, and the telescopic track pump pipe and the telescopic large pump pipe can be flexibly extended and adjusted according to the pouring position and obstacle position, making it suitable for concrete pouring in different locations, and ensuring high safety in use.

Detailed Implementation

[0033] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the quick-assembly type variable amplitude telescopic fabric device proposed in this invention. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0034] Please see the appendix Figure 1 and attached Figure 2A quick-installation variable-amplitude telescopic concrete placing device includes a primary standard placing device 100 and a secondary telescopic variable-amplitude placing device 200. Both the primary standard placing device 100 and the secondary telescopic variable-amplitude placing device 200 are detachably installed on fixed components of a building via clamping assemblies. The inlet of the primary standard placing device 100 is located below the discharge port of the pump truck (not shown in the figure), the outlet of the primary standard placing device 100 extends above the inlet of the secondary telescopic variable-amplitude placing device 200, and the outlet of the secondary telescopic variable-amplitude placing device 200 extends to the pouring position, so that the concrete in the pump truck is pumped to the pouring position through the primary standard placing device 100 and the secondary telescopic variable-amplitude placing device 200.

[0035] For concrete pouring of large foundation slabs and other components in deep foundation pits, traditional pump truck pouring and traditional chute pouring methods cannot adequately meet construction requirements due to the large pouring area and depth. This paper utilizes a combination of a primary standard placing boom 100 and a secondary telescopic boom 200 to replace the traditional chute. Combined with a pump truck, the concrete is transported from above to the pouring location at the bottom of the pit, achieving both concrete placement and pouring. This solves the problem of limited pump truck deployment due to their large space requirements in existing technologies. Furthermore, the primary standard placing boom 100 and the secondary telescopic boom 200 can be detachably installed on fixed structural components, allowing for flexible installation and convenient and quick disassembly and relocation. This solves the problem of inconvenient relocation and transfer of chute systems in existing technologies, resulting in high utilization and ensuring both the efficiency and quality of large foundation slab pouring.

[0036] Please see the appendix Figure 2 The primary standard concrete placing device 100 and the secondary telescopic luffing concrete placing device 200 both include a hopper 1, a rotary assembly 2, and a concrete placing pump pipe. The clamping assembly is installed on the outer wall of the hopper 1, so that the hopper 1 is fixed to the fixed component of the building through the clamping assembly. The rotary assembly 2 is rotatably connected between the discharge port at the bottom of the hopper 1 and the upper end of the concrete placing pump pipe. The hopper 1 of the primary standard concrete placing device 100 is located below the discharge port of the pump truck. The lower end of the concrete placing pump pipe of the primary standard concrete placing device 100 extends to the top of the hopper 1 of the secondary telescopic luffing concrete placing device 200. The lower end of the concrete placing pump pipe of the secondary telescopic luffing concrete placing device 200 extends to the pouring position.

[0037] The hopper 1 of the primary standard placing device 100 is used to receive the concrete pumped by the pump truck and transport it to the secondary telescopic luffing placing device 200 through its placing pump pipe. The hopper 1 of the secondary telescopic luffing placing device 200 is used to receive the concrete transported by the placing pump pipe of the primary standard placing device 100 and transport it to the pouring position through its placing pump pipe, thus realizing the placement of concrete.

[0038] The concrete placing pump pipes of the primary standard placing device 100 and the secondary telescopic luffing placing device 200 are arranged in a downward direction. The rotating component 2 has a rotation function and can rotate to adjust the arrangement direction of the concrete placing pump pipes of the primary standard placing device 100 and the secondary telescopic luffing placing device 200, thereby facilitating the accurate downward delivery of concrete to the pouring position.

[0039] Please see the appendix Figure 3 The rotary assembly 2 includes a rotary pump pipe 201, a rotary arm 202, and a variable amplitude pump pipe 203. The fixed section of the rotary pump pipe 201 is fixedly connected to the discharge port at the bottom of the hopper 1 via a flange. The rotary arm 202 is fixedly mounted on the rotary section of the rotary pump pipe 201. The bottom of the rotary section of the rotary pump pipe 201 is rotatably connected to the top of the variable amplitude section of the variable amplitude pump pipe 203 via a pin 204 and an ear plate 205. The variable amplitude section of the variable amplitude pump pipe 203 and the pump pipe section form an obtuse angle. The pump pipe section of the variable amplitude pump pipe 203 is connected to the upper end of the material distribution pump pipe.

[0040] Preferably, the rotary pump pipe 201 may include a fixed pipe section and a rotary pipe section. The fixed pipe section and the rotary pipe section are coaxially connected circular pipe structures. The fixed pipe section is used to fix the hopper 1 to the hopper 1 through a flange and bolts, which is convenient for disassembly and assembly. The rotary pipe section can rotate relative to the fixed pipe section about its central axis, thereby driving the variable amplitude pump pipe 203 and the placing pump pipe to rotate synchronously, realizing the adjustment of the concrete pumping direction. The rotary pump pipe 201 is a commonly used component in concrete pump pipes, and its specific structure and rotation process will not be described in detail here.

[0041] The diameter of the rotating section of the rotary pump pipe 201 is slightly larger than that of the fixed section. The rotating arm 202 is installed on the rotating section of the rotary pump pipe 201. The rotating arm 202 rotates synchronously with the rotating section of the rotary pump pipe 201 to form a cantilever arm, which facilitates the installation of other components such as wire ropes.

[0042] Preferably, the bottom of the rotary pump pipe 201 is rotatably connected to the ear plate 205 at the top of the luffing section of the luffing pump pipe 203 via a pin 204, so that the luffing pump pipe 203 can rotate up or down around the pin 204, thereby adjusting the concrete delivery and placement angle of the placing pump pipe and controlling the concrete sliding speed.

[0043] Please see the appendix Figure 2 In the first-level standard fabric distribution device 100, the fabric distribution pump pipe includes several sections of standard pump pipe body 3, and the several sections of standard pump pipe body 3 are connected end to end by flanges to form a first-level pumping pipeline; the upper end of the first-level pumping pipeline is connected to the pump pipe section of the luffing pump pipe 203, and the lower end of the first-level pumping pipeline extends to the top of the hopper 1 of the second-level telescopic luffing fabric distribution device 200.

[0044] Based on the hopper spacing of the primary standard concrete placing device 100 and the secondary telescopic luffing concrete placing device 200, a suitable length and number of standard pump pipe bodies 3 can be selected, and two adjacent standard pump pipe bodies 3 can be connected by flanges and bolts to meet the concrete conveying distance requirements in different projects.

[0045] Preferably, lifting lugs can be installed on each standard pump pipe body 3, and multiple lifting holes can be reserved on the rotary arm 202. The lifting lugs of multiple standard pump pipe bodies 3 are respectively connected to the multiple lifting holes of the rotary arm 202 through steel wire ropes, which facilitates the pulling of the standard pump pipe body 3, ensures the stability of the installation and use of the primary pumping pipeline, and also facilitates the adjustment of the pumping angle by rotating the primary pumping pipeline up and down, so as to ensure that the lower end of the primary pumping pipeline can accurately extend to the hopper 1 of the secondary telescopic variable amplitude material distribution device 200.

[0046] Please see the appendix Figure 4 In the secondary telescopic luffing fabric distribution device 200, the fabric distribution pump pipe includes a telescopic track pump pipe 4, a telescopic large pump pipe 5, and a telescopic adjustment assembly. The upper end of the telescopic track pump pipe 4 is connected to the pump pipe section of the luffing pump pipe 203. A telescopic track (not shown in the figure) is formed on the telescopic track pump pipe 4. A track guide wheel 501 matching the telescopic track is installed on the telescopic large pump pipe 5, so that the telescopic large pump pipe 5 can be telescopically connected to the telescopic track pump pipe 4. The telescopic adjustment assembly is installed on the rotating arm 202 and the luffing pump pipe 203 of the secondary telescopic luffing fabric distribution device 200 and is connected to the telescopic large pump pipe 5, so that the lower end of the telescopic large pump pipe 5 can extend to the pouring position or over obstacles.

[0047] The telescopic large pump pipe 5 can move coaxially with the telescopic rail and the telescopic guide wheel 501 relative to the telescopic rail pump pipe 4, thereby more accurately delivering concrete to the appropriate pouring height. At the same time, when moving, the telescopic large pump pipe 5 can avoid obstacles such as beams by rising, avoiding collisions between the telescopic large pump pipe 5 and obstacles in the building structure and ensuring the mobility and safety of the entire device.

[0048] Please see the appendix Figure 4The telescopic adjustment assembly includes an electric hoist 601, a basket hook 602, a wire rope 603, a wire rope guide wheel assembly 604, and a pulley assembly 605. The electric hoist 601 is mounted on the slewing arm 202. One end of the wire rope 603 is connected to the luffing pump pipe 203 via the basket hook 602. At least one set of wire rope guide wheel assemblies 604 is installed on the pump pipe section of the luffing pump pipe 203 via guide wheel seats 606. Several sets of wire rope guide wheel assemblies 604 are installed at intervals on the outer wall of the telescopic large pump pipe 5 via guide wheel seats 606. The pulley assembly 605 is installed on the outer wall of the telescopic large pump pipe 5 via pulley seats 607 and is located between several sets of wire rope guide wheel assemblies 604, so that the other end of the wire rope 603 passes through each set of wire rope guide wheel assemblies 604 in sequence and is connected to the pulley assembly 605.

[0049] An electric hoist 601 can be connected to a wire rope 603 to provide tension to the wire rope 603, causing the wire rope 603 to pull the telescopic pump pipe 5 upward, making it rise axially relative to the telescopic track pump pipe 4, or to release the telescopic pump pipe 5 downward, allowing it to descend axially relative to the telescopic track pump pipe 4 by its own weight. The electric hoist 601 can effectively control the telescopic pump pipe 5 to a suitable height and then stop it. The wire rope 603 is then fixed to the luffing pump pipe 203 by a basket hook 602, keeping the connection length between the telescopic pump pipe 5 and the telescopic track pump pipe 4 fixed.

[0050] Preferably, two wire ropes 603 are used, symmetrically arranged on both sides of the telescopic track pump pipe 4 and the telescopic large pump pipe 5; the wire rope guide wheel assembly 604 is used to guide and pull the two wire ropes 603, and the pulley assembly 605 is used to connect the ends of the two wire ropes 603, ensuring that the telescopic large pump pipe 5 can be stably telescopic under the pull control of the two wire ropes 603.

[0051] Please see the appendix Figure 1 and attached Figure 2 The building's fixing components include a trestle plate 300 and a support beam 400, and the clamping assembly includes a first clamping assembly clamped on the trestle plate 300 and a second clamping assembly 8 clamped on the support beam 400.

[0052] During the construction of deep foundation pits, a trestle plate 300 is usually installed on the top of the first support beam 400 to allow the passage of machinery such as pump trucks. Preferably, the first clamping component through which the first-level standard concrete placing device 100 passes can be fixed on the trestle plate 300, which is stable to install and convenient and quick to disassemble.

[0053] As the deep foundation pit is constructed, multiple support beams 400 are constructed downwards in sequence. The secondary telescopic luffing device 200 can be fixed to the support beam 400 at the corresponding height through the second clamping component 8 according to the pouring height requirements. The installation is stable and the disassembly and assembly are convenient and quick.

[0054] The first and second clamping components enable the entire device to be flexibly installed on existing fixed components of buildings within the foundation pit. The first and second clamping components can be selected according to the size and shape of the fixed components, ensuring reliable installation while achieving quick installation and disassembly.

[0055] Please see the appendix Figure 5 To be continued Figure 8 The first clamping assembly includes several clamping units 7 arranged on both sides of the hopper 1. Each clamping unit 7 includes a vertical plate 701, an adjusting track 702, a first fixing plate 703, a clamping plate 704, an adjusting track wheel 705, a connecting bolt 706, and a clamping hook plate 707. The vertical plate 701 is fixedly installed on the outer wall of the hopper 1 by several bolts. One end of the adjusting track 702 is vertically fixed to the vertical plate 701 by a stiffening plate 708. The first fixing plate 703 is fixedly installed on the top of the adjusting track 702 by a square steel tube 709. The clamping plate... 704 is fixedly installed at the bottom of the adjusting track 702; two sets of adjusting track wheels 705 are slidably set on the adjusting track 702; several connecting bolts 706 are spaced apart on the top of the two sets of adjusting track wheels 705 and fixedly connected to the upper end of the clamping hook plate 707; several waist-shaped holes are formed on the first fixing plate 703, and several connecting bolts 706 pass through several waist-shaped holes respectively; the bottom of the clamping hook plate 707 has an L-shaped structure, so that the horizontal section of the L-shaped structure of the clamping plate 704 and the clamping hook plate 707 are clamped on the top and bottom surfaces of the trestle plate 300 respectively.

[0056] The vertical plate 701, adjusting rail 702, first fixing plate 703, and clamping plate 704 constitute a spreader beam. The spreader beam is bolted to the hopper 1 via the vertical plate 701, facilitating the installation and use of the hopper 1. The vertical plate 701, first fixing plate 703, clamping plate 704, and stiffening plate 708 can be made of steel plate, and the adjusting rail 702 can be made of I-beams. The spreader beam is welded into a single structure, resulting in high structural strength.

[0057] The adjusting track wheel 705, connecting bolt 706, and clamping hook plate 707 constitute the adjusting hook plate. Two sets of adjusting track wheels 705 can roll along the waist-shaped holes on both sides of the web of the I-beam, giving the clamping hook plate 707 a small adjustment function. The connecting bolt 706 can be installed above the adjusting track wheel 705 through the mounting plate, and a nut is installed on the mounting plate. The rotation of the nut controls the upward or downward movement of the connecting bolt 706 through thread transmission. The connecting bolt 706 drives the clamping hook plate 707 to move upward or downward synchronously, thereby adjusting the distance between the horizontal section of the L-shaped structure of the clamping hook plate 707 and the clamping plate 704 to accommodate different thicknesses of the trestle plate 300, ensuring that the clamping unit 7 is firmly and reliably clamped on the trestle plate 300.

[0058] During installation, a unit plate of the trestle plate 300 can be detached, and the hopper 1 is placed in the hollowed-out part of the detached unit plate. It is then fixed to the unit plates on both sides of the unit plate by four clamping units 7 to ensure the reliability of the installation of the hopper 1. Preferably, four sets of clamping units 7 can be set, and the number of clamping units 7 can be adjusted according to actual needs. The clamping units 7 can be set symmetrically or asymmetrically to ensure clamping while also adapting to installation on mounting surfaces at different heights on both sides.

[0059] Please see the appendix Figure 9 To be continued Figure 11 The second clamping assembly 8 includes a second fixing plate 801, a support rail 802, a hopper support foot 803, support legs 804, a spiral push rod 805, rollers 806, a hopper support plate 807, and an operating platform 808. One end of the second fixing plate 801 and the support rail 802 are respectively set on the outer wall of the hopper 1. A set of rollers 806 are respectively installed on the top of the hopper support foot 803. The rollers 806 are slidably installed on a support rail 802 and locked in place by bolts. A pair of support legs 804... One end of the screw push rod 805 is connected to the hopper support plate 807, and the other end of the pair of support legs 804 slides through the hopper support foot 803. The screw push rod 805 rotates through the hopper support foot 803, so that the hopper support plate 807 is adjustablely installed on the hopper support foot 803 and is opposite to the other end of the second fixed plate 801, so that the other ends of the hopper support plate 807 and the second fixed plate 801 can be clamped on the two sides of the support beam 400 respectively; the operating platform 808 is installed on the hopper support foot 803.

[0060] Preferably, a pair of second fixing plates 801 and support rails 802 are symmetrically arranged. Each support rail 802 is equipped with a corresponding hopper support foot 803 via rollers 806. The hopper support foot 803 can move along the support rail 802 via rollers 806, thereby adjusting the distance between the hopper support foot 803 and the second fixing plate 801 (i.e., adjusting the distance between the hopper support plate 807 and the second fixing plate 801), so that the hopper support plate 807 and the second fixing plate 801 are clamped on both sides of the support beam 400. The support rails 802 rest on the top surface of the support beam 400, and the rollers 806 are locked by bolts or other means, thereby ensuring that the second clamping assembly 8 stably fixes the hopper 1 on the support beam 400.

[0061] Preferably, the two support legs 804, the screw push rod 805, and the hopper support plate 807 form a set of fine-tuning components, with two sets of fine-tuning components arranged vertically on each hopper support leg 803. The screw push rod 805 is screwed perpendicularly to the hopper support leg 803 via threads. The two support legs 804 pass perpendicularly through the hopper support leg 803 and are located above and below the screw push rod 805, respectively, to improve the adjustment stability and linearity of the screw push rod 805. When the screw push rod 805 rotates in the forward or reverse direction, it can drive the hopper support plate 807 to move away from or closer to the hopper support leg 803, thereby pressing the hopper support plate 807 against the side of the support beam 400 or disengaging it from the support beam 400, thus ensuring the pressing effect of the hopper support leg 803 on the support beam 400.

[0062] An operating platform 808 is installed between the two hopper support legs 803 to provide standing space for construction personnel, thereby facilitating the clamping or loosening adjustment of each set of fine-tuning components.

[0063] Please see the appendix Figure 1 To be continued Figure 11 The conventional installation method of this invention is as follows: The primary standard placing device 100 is installed on the trestle plate 300 via the first clamping assembly. The pump truck travels on the trestle plate 300 and pumps concrete into the hopper 1 of the primary standard placing device 100. The secondary telescopic luffing placing device 200 is installed on the support beam 400 of the foundation pit via the second clamping assembly 8. The hopper 1 of the secondary telescopic luffing placing device 200 is located at the lower end of the primary pumping pipe of the primary standard placing device 100. The lower end of the telescopic large pump pipe 5 of the secondary telescopic luffing placing device 200 extends to the pouring position, so that concrete is transported to the pouring position through the primary standard placing device 100 and the secondary telescopic luffing placing device 200, thereby realizing the concrete placement and pouring construction.

[0064] The installation method of the first-level standard fabric feeding device 100 on the trestle plate 300 is as follows: the four-assembly clamping unit 7 of the first clamping component is installed on both sides of the hopper 1, and the four-assembly clamping unit 7 is connected to the two unit plates of the trestle plate 300 on both sides of the hopper 1, thereby fixing the hopper 1 on the trestle plate 300.

[0065] According to the direction of concrete delivery, the extension direction of the luffing pump pipe 203 is adjusted by horizontally rotating the rotary pump pipe 201. Simultaneously, according to the concrete delivery requirements, the luffing pump pipe 203 is rotated up and down via the pin 204 to ensure that the angle between its pipe section and the horizontal plane meets the concrete placement requirements, thus guaranteeing that the concrete can be delivered downwards at the designed speed. Preferably, a baffle 206 can be installed on the pin 204 to limit the rotation angle of the luffing section of the luffing pump pipe 203.

[0066] After adjustment, lock and fix the ear plate 205 and pin 204. Then, according to the installation height of the secondary telescopic luffing fabric distribution device 200, select an appropriate number of standard pump pipe bodies 3 and connect them sequentially to the pump pipe sections of the luffing pump pipe 203 using bolts and flanges, extending them to the hopper of the secondary telescopic luffing fabric distribution device 200. After each standard pump pipe body 3 is installed, it can be connected to the pre-reserved lifting holes on the slewing arm 203 via steel wire ropes, thereby improving the load-bearing capacity of the standard pump pipe body 3.

[0067] Based on the width of the support beam 400, the distance between the hopper support foot 803 and the second fixed plate 801 is first adjusted by the roller 806, and the roller 806 is locked so that a pair of second fixed plates 801, a pair of support foot tracks 802 and a pair of hopper support feet 803 form an inverted U-shaped structure with a width slightly larger than the width of the support beam 400, so that the secondary telescopic luffing fabric device 200 can be hung on the support beam 400.

[0068] The construction worker stands inside the operating platform 808 and rotates the spiral push rod 805. Using the threaded transmission between the spiral push rod 805 and the hopper support foot 803, the hopper support plate 807 is moved towards the side of the support beam 400 and pressed against the support beam 400. This causes the four hopper support plates 807 and a pair of second fixing plates 801 to clamp the support beam 400 from both sides, thereby making the secondary telescopic luffing fabric distribution device 200 stably installed on the support beam 400.

[0069] Similar to the first-level standard concrete placing device 100, the extension direction of the telescopic track pump pipe 4 and the telescopic large pump pipe 5 of the second-level telescopic luffing concrete placing device 200 is adjusted by the rotary pump pipe 201 according to the location of concrete pouring. The extension angle of the telescopic track pump pipe 4 and the telescopic large pump pipe 5 is adjusted by the luffing pump pipe 203 via the pin 204 and the ear plate 205. This will not be described in detail here.

[0070] The electric hoist 601, via steel wire rope 603, pulls the telescopic pump pipe 5, causing it to extend relative to the telescopic track pump pipe 4. This extends the lower end of the telescopic pump pipe 5 to the pouring position. The steel wire rope 603 is connected to the luffing pump pipe 203 via a basket hook 602. After adjustment, concrete is transported by a pump truck to the primary standard placing device 100, then placed into the secondary telescopic luffing placing device 200, and finally placed to the pouring position via the telescopic pump pipe 5. This achieves a highly efficient concrete placement and pouring process, with a single-point placement efficiency of 100-120m. 3 / h.

[0071] When the pouring position changes, the primary standard placing device 100 and / or the secondary telescopic luffing placing device 200 can be disassembled according to the actual working conditions. Since both the primary standard placing device 100 and the secondary telescopic luffing placing device 200 have rotation and length adjustment functions, they can be disassembled and installed simultaneously or independently according to the adjusted concrete conveying requirements. This allows for rapid disassembly and assembly while meeting concrete placement needs, resulting in greater flexibility. The installation of a single set of the primary standard placing device 100 and the secondary telescopic luffing placing device 200 takes only about 30 minutes, and the simplified design of the first and second clamping components and their flexible disassembly and assembly methods greatly improve the device's turnaround rate.

[0072] When moving or rotating the secondary telescopic luffing concrete placing device 200, interference and collisions are inevitable due to the presence of building components such as support beams 400 in the deep foundation pit. The telescopic pump pipe 5 can be pulled upward by the electric hoist 601 and the steel wire rope 603 to avoid obstacles and ensure the safety of construction. This allows for cross-bin concrete placing and greatly expands the placing range.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
