Abstract

The present application relates to the technical field of forming maintenance equipment, in particular to a concrete pole forming and maintenance integrated manufacturing equipment. It comprises a pair of limiting bolts arranged on the top of the base, and a forming shaft is rotatably connected between the two limiting bolts. A pair of sealing flanges are arranged on the outside of the forming shaft. When the forming shaft rotates synchronously with the shell, the concrete in the mold cavity is thrown to the side wall of the shell, and the driving wedge rotates synchronously with the forming shaft. Under the action of the centrifugal force of the forming shaft, the guide rod and the driving wedge slide relatively, that is, the push plate moves away from the axis of the forming shaft. Under the conversion effect of the slope of the driving wedge and the second slope, the driving wedge moves along the radial direction of the forming shaft, and the axial sealing ring moves along the axial direction of the forming shaft. Thus, the two axial sealing rings move towards each other and press the concrete in the mold cavity along the axial direction, thereby improving the axial structural strength of the cement pole.

Description

Technical Field

[0001] This invention relates to the field of molding and curing equipment technology, and more specifically, to an integrated manufacturing equipment for molding and curing concrete poles. Background Technology

[0002] Concrete poles are widely used in power transmission and communication infrastructure, and centrifugal molding is the mainstream manufacturing process for concrete poles. Existing centrifugal molding equipment relies on driving a steel mold to rotate at high speed, using centrifugal force to force concrete material to adhere to the inner wall of the mold cavity, completing the radial compaction of the concrete and thus forming the pole structure. This molding method is simple to operate and is widely used in the industry.

[0003] Traditional centrifugal molding equipment for concrete poles can only achieve unidirectional radial compaction of materials. The concrete within the mold cavity is only subjected to radial compression, lacking effective axial compaction. This results in a loose axial distribution of concrete within the mold cavity, leading to uneven axial density in the molded pole body. This directly results in insufficient axial structural strength of the concrete pole, making the produced poles prone to quality defects and unable to meet high-standard engineering requirements. To improve the axial density of the poles, existing technologies add an independent axial clamping mechanism, requiring additional power components and an independent control system, resulting in complex equipment structures and high investment costs.

[0004] In view of this, we propose an integrated manufacturing equipment for the molding and curing of concrete poles to improve the above-mentioned shortcomings. Summary of the Invention

[0005] This invention provides an integrated manufacturing equipment for the molding and curing of concrete poles, which solves the problem that existing concrete in the mold cavity is only subjected to radial compression, and the material lacks an effective means of axial compaction.

[0006] To achieve the above objectives, the integrated manufacturing equipment for forming and curing concrete poles includes a pair of limiting bolts set on the top of the base, and a forming shaft is rotatably connected between the two limiting bolts. A pair of sealing flanges are spaced apart on the outside of the forming shaft. A housing is fixedly connected between the two sealing flanges on the outside of the forming shaft. The inner wall of the housing and the outer wall of the forming shaft form a forming cavity. The outer side of the housing is provided with a radial compaction assembly, which is used to drive the housing and the forming shaft to rotate synchronously. The two ends of the forming shaft that are far apart are provided with axial compaction assemblies, and each axial compaction assembly is provided with a throwing assembly between it and the sealing flange. The ejector assembly is fixed in the axial direction relative to the forming shaft, and the ejector assembly is slidably connected to the forming shaft in the radial direction. When the ejector assembly slides relative to the forming shaft, the ejector assembly pushes the two axial compaction assemblies closer to each other to compact the cement rod in the cavity in the axial direction.

[0007] In the above technical solution, concrete material is injected into the cavity through an injection pipe, specifically as follows: Figure 7 The concrete injected into the injection pipe generates an axial pushing force on the first inclined surface outside the stop block. Under the conversion effect of the first inclined surface, part of the thrust pushes the connecting plate to slide upward. The limiting plate is pushed upward in the limiting cavity by the connecting plate. During this process, the first spring is compressed and stores elastic potential energy. After the injection is completed, the limiting cavity is reset under the action of the restoring force of the first spring, blocking the injection pipe. The side of the stop block near the cavity is a flat surface, not an inclined surface as shown by the first inclined surface, thus preventing the concrete material in the cavity from flowing out.

[0008] Based on this, the limiting bolt is fixedly provided with a fixing bolt on the side near the housing, the driven gear is fixedly installed on the outside of the housing, and the driving gear is rotatably connected to one side of the fixing bolt.

[0009] Furthermore, the driven gear meshes with the driving gear, and a drive motor for driving the driving gear to rotate is provided on one side of the fixed mounting bolt.

[0010] The drive motor includes a body and an output shaft. The body of the drive motor is fixedly connected to a mounting bolt, and the output shaft of the drive motor is coaxially connected to the drive gear.

[0011] With this design, after the cavity is filled with concrete material through the injection pipe, the power of the drive motor is turned on, and its output shaft drives the drive gear to rotate. Under the transmission action of the driven gear, the shell and the forming shaft rotate synchronously between the two limit bolts. Thus, under the action of centrifugal force, the concrete in the cavity moves towards the inner side wall of the shell, that is, it produces a radial compaction effect on the concrete in the cavity.

[0012] In another technical solution, the axial compaction assembly includes an axial sealing ring, an inner limiting ring is fixedly provided on the inner side of the axial sealing ring, and a second inclined surface is formed between the axial sealing ring and the inner limiting ring. The width of the second inclined surface gradually decreases along the centripetal direction of the axial sealing ring.

[0013] Furthermore, a number of sliding rods are fixedly connected to one side of the axial sealing ring, and each sliding rod is fitted with a sealing flange. The outer wall of the axial sealing ring slides against the inner wall of the housing, and the inner wall of the inner limiting ring slides against the outer wall of the forming shaft.

[0014] Furthermore, a limit cap is fixedly connected to the end of the slide rod away from the axial sealing ring, and a second spring is sleeved on the outside of the slide rod between the limit cap and the sealing flange.

[0015] Based on the above description, the preferred effect of the ejection assembly will be explained below. The ejection assembly includes a plurality of mounting cavities opened in the radial direction of the forming axis, and the plurality of mounting cavities are distributed in a ring array.

[0016] The improvement is that a push plate is slidably connected inside the mounting cavity, and a guide rod is fixedly connected to one end of the push plate away from the forming shaft axis. The guide rod passes through the mounting cavity and the molded cavity.

[0017] Preferably, a drive wedge is fixedly connected to one end of the guide rod located inside the push plate, and the inclined surface of the drive wedge slides in contact with the second inclined surface.

[0018] In this technical solution, after the forming shaft and the shell rotate synchronously, the concrete in the cavity is thrown towards the side wall of the shell, and the driving wedge rotates synchronously with the forming shaft. Under the action of the centrifugal force of the forming shaft, the guide rod and the driving wedge slide relative to each other, that is, the push plate moves away from the axis of the forming shaft. Under the conversion action of the inclined surface and the second inclined surface of the driving wedge, the radial movement of the driving wedge along the forming shaft is converted into the axial movement of the axial sealing ring along the forming shaft. As a result, the two axial sealing rings approach each other and compress the concrete in the cavity along the axial direction, thereby improving the axial structural strength of the cement rod.

[0019] During this period, the third spring sleeved on the outside of the guide rod and the second spring sleeved on the outside of the slide rod are compressed and stored as elastic potential energy. After the cement rod is formed in the cavity, the axial sealing ring and the drive wedge are reset under the action of the restoring force of the second spring and the third spring, respectively.

[0020] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: When the forming shaft rotates synchronously with the shell, the concrete in the cavity is thrown towards the side wall of the shell. At the same time, the drive wedge rotates synchronously with the forming shaft. Under the action of the centrifugal force of the forming shaft, the guide rod and the drive wedge slide relative to each other, that is, the push plate moves away from the axis of the forming shaft. Under the conversion action of the inclined surface and the second inclined surface of the drive wedge, the radial movement of the drive wedge along the forming shaft is converted into the axial movement of the axial sealing ring along the forming shaft. As a result, the two axial sealing rings approach each other and compress the concrete in the cavity along the axial direction, thereby improving the axial structural strength of the cement rod.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Traditional centrifugal molding equipment for concrete poles can only achieve unidirectional radial compaction of materials. The concrete within the mold cavity is only subjected to radial compression, lacking effective axial compaction. This results in a loose axial distribution of concrete within the mold cavity, leading to uneven axial density in the molded pole body. This directly results in insufficient axial structural strength of the concrete pole, making the produced poles prone to quality defects and unable to meet high-standard engineering requirements. To improve the axial density of the poles, existing technologies add an independent axial clamping mechanism, requiring additional power components and an independent control system, resulting in complex equipment structures and high investment costs.

[0027] Please see Figure 1 and Figure 2 In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a concrete pole forming and curing integrated manufacturing equipment, the manufacturing equipment including a pair of limiting bolts (110) disposed on the top of the base (100), and a forming shaft (130) rotatably connected between the two limiting bolts (110). A pair of sealing flanges (131) are provided at intervals on the outside of the forming shaft (130). A housing (120) is fixedly connected between the two sealing flanges (131) on the outside of the forming shaft (130). The inner wall of the housing (120) and the outer wall of the forming shaft (130) form a forming cavity (140). A radial compaction assembly (200) is provided on the outside of the housing (120). The radial compaction assembly (200) is used to drive the housing (120) and the forming shaft (130) to rotate synchronously. An axial compaction assembly (300) is provided at both ends of the forming shaft (130) that are far apart. A throwing assembly (400) is provided between each axial compaction assembly (300) and the sealing flange (131). The ejector assembly (400) is fixed in the axial direction relative to the forming shaft (130), and the ejector assembly (400) is slidably connected to the forming shaft (130) in the radial direction. When the ejector assembly (400) slides relative to the forming shaft (130), the ejector assembly (400) pushes the two axial compaction assemblies (300) to move closer to each other, so as to compact the cement rod in the cavity (140) in the axial direction.

[0028] During implementation, concrete material is injected into the cavity (140) through the injection pipe (150), specifically as follows: Figure 7 The concrete injected into the injection pipe (150) generates an axial pushing force on the first inclined surface (156) on the outside of the stop block (152). Under the conversion effect of the first inclined surface (156), part of the pushing force pushes the connecting plate (154) to slide upward. The limiting plate (153) is pushed by the connecting plate (154) to slide upward in the limiting cavity (151). During this time, the first spring (155) is compressed and stores elastic potential energy. After the injection is completed, the limiting cavity (151) is reset under the action of the restoring force of the first spring (155), blocking the injection pipe (150). The side of the stop block (152) near the cavity (140) is a flat surface, not an inclined surface as shown by the first inclined surface (156), thereby preventing the concrete material in the cavity (140) from flowing out.

[0029] Next, as Figure 3 and Figure 4 As shown, the limiting bolt (110) has a fixed mounting bolt (201) fixedly installed on the side near the housing (120), the driven gear (210) is fixedly installed on the outside of the housing (120), and the driving gear (220) is rotatably connected to one side of the fixed mounting bolt (201).

[0030] Furthermore, the driven gear (210) meshes with the driving gear (220), and a drive motor (230) for driving the driving gear (220) to rotate is provided on one side of the fixed mounting bolt (201).

[0031] The drive motor (230) includes a body and an output shaft. The body of the drive motor (230) is fixedly connected to a mounting bolt (201), and the output shaft of the drive motor (230) is coaxially connected to a drive gear (220).

[0032] It should be noted that after the cavity (140) is filled with concrete material through the injection pipe (150), the power supply of the drive motor (230) is turned on, so that its output shaft drives the drive gear (220) to rotate. Under the transmission action of the driven gear (210), the shell (120) and the forming shaft (130) rotate synchronously between the two limit bolts (110). Thus, under the action of centrifugal force, the concrete in the cavity (140) moves towards the inner side wall of the shell (120), that is, it generates radial compaction effect on the concrete in the cavity (140).

[0033] After the radial compaction described above, the concrete material in the cavity (140) is still not compacted axially, which will result in insufficient axial structural strength of the resulting utility pole. In this application, the axial compaction assembly (300) is used to compact both ends of the material in the cavity (140) to compensate for the above deficiency. See details below. Figure 5 and Figure 6 .

[0034] The axial compaction assembly (300) includes an axial sealing ring (310), and an inner limiting ring (320) is fixedly provided on the inner side of the axial sealing ring (310). A second inclined surface (330) is formed between the axial sealing ring (310) and the inner limiting ring (320). The width of the second inclined surface (330) gradually decreases along the centripetal direction of the axial sealing ring (310).

[0035] Furthermore, a number of slide rods (340) are fixedly connected to one side of the axial sealing ring (310), and each slide rod (340) is provided with a sealing flange (131). The outer wall of the axial sealing ring (310) slides against the inner wall of the housing (120), and the inner wall of the inner limiting ring (320) slides against the outer wall of the forming shaft (130).

[0036] Furthermore, a limit cap is fixedly connected to the end of the slide rod (340) away from the axial sealing ring (310), and a second spring (350) is sleeved on the outside of the slide rod (340) between the limit cap and the sealing flange (131).

[0037] Based on the above explanation, the following will be further explained... Figure 8 To explain the preferred effect of the ejection assembly (400), the ejection assembly (400) includes a plurality of mounting cavities (401) opened radially on the forming shaft (130), and the plurality of mounting cavities (401) are distributed in a ring array.

[0038] The improvement is that a push plate (410) is slidably connected in the mounting cavity (401), and a guide rod (420) is fixedly connected to one end of the push plate (410) away from the axis of the forming shaft (130). The guide rod (420) passes between the mounting cavity (401) and the cavity (140).

[0039] Preferably, one end of the guide rod (420) located inside the push plate (410) is fixedly connected to a driving wedge (430), and the inclined surface of the driving wedge (430) slides against the second inclined surface (330).

[0040] In other words, when the forming shaft (130) and the shell (120) rotate synchronously, the concrete in the cavity (140) is thrown towards the side wall of the shell (120), and the driving wedge (430) rotates synchronously with the forming shaft (130). Under the action of the centrifugal force of the forming shaft (130), the guide rod (420) and the driving wedge (430) slide relative to each other, that is, the push plate (410) moves away from the axis of the forming shaft (130). Under the conversion action of the inclined surface and the second inclined surface (330) of the driving wedge (430), the radial movement of the driving wedge (430) along the forming shaft (130) is converted into the axial movement of the axial sealing ring (310) along the forming shaft (130). Thus, the two axial sealing rings (310) approach each other and compress the concrete in the cavity (140) along the axial direction, thereby improving the axial structural strength of the cement rod.

[0041] During this period, the third spring (440) sleeved on the outside of the guide rod (420) and the second spring (350) sleeved on the outside of the slide rod (340) are compressed and stored in elastic potential energy. After the cement rod is formed in the cavity (140), the axial sealing ring (310) and the driving wedge (430) are reset under the action of the restoring force of the second spring (350) and the third spring (440), respectively.

[0042] The working principle of this manufacturing equipment will be explained in more detail below: First, concrete material is injected into the cavity (140) through the injection pipe (150); the concrete material impacts the first inclined surface (156) of the stop block (152) to generate axial thrust, which pushes the connecting plate (154) and the limiting plate (153) to slide in the limiting cavity (151) and compress the first spring (155); after the injection is completed, the first spring (155) releases its elastic force to drive the component to reset and seal the injection pipe (150), and relies on the plane of the stop block (152) to block the leakage of concrete inside the cavity (140).

[0043] Next, the drive motor (230) is started. The drive motor (230) drives the active gear (220) to rotate, and through meshing transmission, drives the driven gear (210) to rotate, causing the housing (120) and the forming shaft (130) to rotate synchronously. Under the action of centrifugal force, the concrete inside the cavity (140) gathers towards the inner wall of the housing (120), realizing radial compaction of the concrete.

[0044] During the rotation of the forming shaft (130), the push plate (410) moves away from the axis of the forming shaft (130) under the action of centrifugal force, which drives the guide rod (420) and the drive wedge (430) to move radially. The drive wedge (430) slides relative to the second inclined surface (330) on the axial sealing ring (310), converting the radial movement into axial displacement, pushing the two sets of axial sealing rings (310) closer to each other, and axially compacting the concrete in the cavity (140).

[0045] When the axial sealing ring (310) moves, it compresses the second spring (350) on the outside of the slide bar (340), and the guide rod (420) moves to compress the third spring (440). After the concrete pole is formed, the centrifugal force disappears, and the second spring (350) and the third spring (440) release elastic potential energy, driving the axial sealing ring (310) and the drive wedge (430) to reset.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
