Anti-collapse structure for recycled concrete pole production

Abstract

This utility model relates to the field of power pole production technology and discloses an anti-collapse structure for the production of recycled concrete power poles. It includes a main shaft with a cross groove on its outer wall. A support assembly is disposed inside the cross groove, and the support assembly includes two symmetrically arranged sliders connected by a bidirectional threaded rod. One end of the bidirectional threaded rod is rotatably connected to the inner wall of the cross groove, and the other end is fixedly connected to a rotating wheel. This anti-collapse structure for recycled concrete power pole production allows for flexible rotation of the rotating wheel to drive the bidirectional threaded rod, moving the slider within the cross groove. This, in turn, causes the support plate to change its support angle and height against the horizontal plate, ensuring the horizontal plate fits tightly against the inner wall of the power pole and provides stable and uniform lateral support. This effectively avoids the problem of power pole collapse caused by insufficient or uneven support.

Description

Technical Field

[0001] This utility model relates to the field of pole production technology, specifically to an anti-collapse structure for the production of recycled concrete poles. Background Technology

[0002] In the field of recycled concrete pole production, with the increasing demands for environmental protection and resource recycling in the construction industry, recycled concrete has gradually become an important material for pole production due to its advantages such as effectively utilizing waste concrete and saving natural aggregate resources. However, pole collapse has always been a key challenge affecting production quality and efficiency during the production process of recycled concrete poles.

[0003] Currently, traditional pole production anti-collapse structures mostly employ fixed support designs. The dimensions and angles of these fixed support structures are typically pre-set for specific pole specifications, making flexible adjustments difficult for poles of different sizes. In actual production, poles come in various specifications, with different diameters and lengths. Traditional fixed support structures cannot precisely adapt, often resulting in uneven support force and unreasonable support points. This leads to pole collapse during casting and curing due to insufficient support, severely affecting the pole's molding quality and resulting in a high scrap rate. For example, when producing poles of different diameters, traditional support structures either fail to provide sufficient lateral support or damage the pole mold due to excessive support.

[0004] Meanwhile, existing anti-collapse structures have significant shortcomings in terms of support angle adjustment. The inner walls of utility poles are not all perfectly vertical; they exhibit various angles of inclination. Traditional support structures have fixed support angles, making it difficult to dynamically adjust them based on the actual inclination of the pole's inner walls and the complex stress conditions experienced during production. This leads to a mismatch between the direction of the support force and the actual stress direction on the pole, preventing the support structure from fully functioning. Under uneven stress, the pole is highly susceptible to deformation and even collapse. Furthermore, traditional structures cannot effectively adjust the support strength and angle in a timely manner when facing pressure changes caused by the material properties of recycled concrete during pouring, further increasing the risk of pole collapse. Utility Model Content

[0005] The purpose of this invention is to provide an anti-collapse structure for the production of recycled concrete poles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-collapse structure for the production of recycled concrete poles, comprising a main shaft, a cross groove formed on the outer wall of the main shaft, a support assembly provided inside the cross groove, the support assembly comprising sliders, two sets of sliders symmetrically arranged, and the two sets of sliders being threadedly connected by a bidirectional threaded rod, one end of the bidirectional threaded rod being rotatably connected to the inner wall of the cross groove, the other end of the bidirectional threaded rod being fixedly connected to a rotating wheel, a support plate being hinged to the end of the slider, and a cross plate being hinged to the end of the support plate.

[0007] Preferably, an angle adjustment component is provided on the surface of the horizontal plate. The angle adjustment component includes a fixed frame, which is fixedly connected to the surface of the horizontal plate. A movable seat is slidably connected inside the fixed frame. A through hole is opened on the side wall of the movable seat, and a lead screw is threaded into the through hole.

[0008] Preferably, the lead screw passes through and is rotatably connected to the side wall of the fixed frame, and one end of the lead screw is rotatably connected to the inner wall of the fixed frame.

[0009] Preferably, a traction plate is hinged to the surface of the movable seat, an adjustment plate is hinged to the end of the traction plate, and the end of the adjustment plate is hinged to the surface of the support plate.

[0010] Preferably, the bidirectional threaded rod is rotatably connected to the end of the main shaft.

[0011] Preferably, a rotating wheel is fixedly connected to the other end of the lead screw.

[0012] Compared with the prior art, this utility model provides an anti-collapse structure for the production of recycled concrete poles, which has the following beneficial effects:

[0013] 1. This anti-collapse structure for recycled concrete pole production utilizes adjustable support components, namely a two-way threaded rod, a slider, a support plate, and a cross plate. Operators can flexibly rotate the rotating wheel to drive the two-way threaded rod according to the actual size of the pole, causing the slider to move within the cross groove. This, in turn, alters the support plate's angle and height relative to the cross plate, ensuring the cross plate fits tightly against the inner wall of the pole and provides stable and uniform lateral support. Compared to traditional fixed support structures, this significantly improves adaptability to poles of different specifications, effectively preventing pole collapse due to insufficient or uneven support, and substantially improving pole production quality and yield.

[0014] 2. The anti-collapse structure for the production of recycled concrete poles is equipped with an angle adjustment assembly. The fixed frame, moving seat, lead screw, traction plate, and adjustment plate work together. Based on the different inclinations of the pole's inner wall and the complex stress conditions experienced during actual production, rotating the second wheel causes the lead screw to rotate, driving the moving seat to slide within the fixed frame. This, in turn, causes the adjustment plate to change the angle of the support plate via the traction plate. This dynamic adjustment design allows the support structure to more precisely adapt to the actual condition of the pole, adjusting the support force to the most reasonable direction and further enhancing the support effect on the pole.

[0019] like Figures 1-3 As shown, this utility model provides a technical solution: an anti-collapse structure for the production of recycled concrete poles, including a main shaft 1. A cross groove 2 is formed on the outer wall of the main shaft 1. A support assembly 3 is disposed inside the cross groove 2. The support assembly 3 includes sliders 31, with two sets of sliders 31 symmetrically arranged. The two sets of sliders 31 are threadedly connected by a bidirectional threaded rod 32. The bidirectional threaded rod 32 passes through and is rotatably connected to the end of the main shaft 1. One end of the bidirectional threaded rod 32 is rotatably connected to the inner wall of the cross groove 2, and the other end of the bidirectional threaded rod 32 is fixedly connected to a rotating wheel 33. A support plate 34 is hinged to the end of the sliders 31, and a horizontal plate 35 is hinged to the end of the support plate 34. The main shaft 1 is inserted into the interior of the pole. The sliders 31 are adapted to the shape of the cross groove 2. The rotating wheel 33 is used to adjust the rotation of the bidirectional threaded rod 32, thereby driving the two sets of sliders 31 to move downwards. The support plate 34 supports and adjusts the height of the horizontal plate 35, causing the horizontal plate 35 to approach the inner wall of the pole.

[0020] like Figures 1-3As shown, an angle adjustment assembly 4 is provided on the surface of the horizontal plate 35. The angle adjustment assembly 4 includes a fixed frame 41, which is fixedly connected to the surface of the horizontal plate 35. A movable seat 42 is slidably connected inside the fixed frame 41. The fixed frame 41 guides the movable seat 42, enabling the movable seat 42 to move stably. A through hole is provided on the side wall of the movable seat 42, and a lead screw 43 is threaded into the through hole. The lead screw 43 passes through and is rotatably connected to the side wall of the fixed frame 41. One end of the lead screw 43 is rotatably connected to the inner wall of the fixed frame 41, and the other end of the lead screw 43 is fixedly connected to a rotating wheel 44. By rotating the rotating wheel 44, the operator can easily adjust the lead screw 43, thereby controlling the position of the movable seat 42. A traction plate 45 is hinged to the surface of the movable seat 42, and an adjustment plate 46 is hinged to the end of the traction plate 45. The end of the adjustment plate 46 is hinged to the surface of the support plate 34. When the movable seat 42 slides under the drive of the lead screw 43, the traction plate 45 drives the support plate 34 to change its angle, thereby realizing the adjustment of the angle of the support structure, so that the adjustment plate 46 fits against the inner wall with different inclinations.

[0021] In this invention, during use, the pole mold is first cleaned and placed in a suitable production position, ensuring that the mold is level and stable. Then, the main shaft 1 is inserted into the inside of the pole mold, positioning the main shaft 1 at the center of the pole, ensuring that the subsequent support assembly 3 and angle adjustment assembly 4 can provide uniform support to the pole.

[0022] Rotating the first rotating wheel 33 causes the bidirectional threaded rod 32 to rotate. Since the threads at both ends of the bidirectional threaded rod 32 have opposite directions and are threadedly connected to two sets of sliders 31, the two sets of sliders 31 will move towards or away from each other along the cross groove 2 when the bidirectional threaded rod 32 rotates. During this process, as the two sets of sliders 31 move towards each other, the support plate 34 hinged to the end of the slider 31 changes its tilt angle as the slider 31 moves, thereby supporting the horizontal plate 35 and adjusting its height, causing the horizontal plate 35 to gradually approach the inner wall of the pole. When the horizontal plate 35 contacts the inner wall of the pole and provides a certain supporting force, the rotation of the first rotating wheel 33 stops. At this point, the support assembly 3 completes the initial support positioning, providing basic lateral support for the pole and preventing the pole from collapsing due to uneven lateral force during production.

[0023] Based on the inclination of the inner wall of the pole and the actual stress conditions, the rotating wheel 44 is rotated. The rotating wheel 44 drives the lead screw 43 to rotate. The lead screw 43 is threadedly connected to the through hole on the side wall of the moving seat 42, so the rotation of the lead screw 43 causes the moving seat 42 to slide within the fixed frame 41 along the axial direction of the lead screw 43. A traction plate 45 is hinged to the surface of the moving seat 42. When the moving seat 42 slides, the traction plate 45 is pulled, which in turn drives the adjusting plate 46 to move. The end of the adjusting plate 46 is hinged to the surface of the support plate 34. The movement of the traction plate 45 causes the adjusting plate 46 to change the angle of the support plate 34, thereby adjusting the angle of the support structure so that the adjusting plate 46 can fit against the inner wall of the pole with different inclinations. In this way, the support structure can provide a more reasonable direction of support force according to the actual situation of the pole, further enhancing the support effect of the pole and effectively preventing the pole from collapsing during production.

[0024] During the production of recycled concrete poles, such as concrete pouring and vibration, the condition of the pole and the stress on the supporting structure should be closely observed. If any loosening, displacement, or deformation of the pole is found in the supporting structure, the first wheel 33 or the second wheel 44 can be rotated again to make fine adjustments to the supporting component 3 or the angle adjustment component 4, ensuring that the supporting structure can always effectively support the pole and guarantee the smooth progress of pole production.

[0025] Once the recycled concrete poles are produced and reach the specified strength, demolding is performed. First, the rotating wheel 33 is rotated in the opposite direction, causing the two sets of sliders 31 to move in opposite directions, which in turn retracts the support plate 34 and the horizontal plate 35, separating them from the inner wall of the pole. Then, the main shaft 1 is removed from inside the pole, and the support structure is cleaned and inspected to prepare for the next use.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
