Abstract
Description
Technical Field
[0001] This application relates to the field of power engineering construction technology, and in particular to a support structure for power construction. Background Technology
[0002] During power construction, it is often necessary to connect and install various power pipelines. For power pipelines with large diameter and heavy weight, the connection is often difficult and the connection effect is poor, resulting in rework and extended construction period.
[0003] A related technology proposes a support structure for power construction, including a support plate, a gear, a first rack, a second rack, and a limiting plate. The limiting plates are rotatably connected to both sides of the support plate along its width, with two limiting plates symmetrically rotatably connected to each side of the support plate. The gear is rotatably connected below the support plate, and the first and second racks mesh with the top and bottom of the gear, respectively. Each end of the first and second racks is equipped with a pressing rod and a support member. The pressing rod is located outside the limiting plate to press against it. Rotating the gear drives the first and second racks to move closer or further apart, and both the first and second racks move along the length of the support plate. In use, two power pipes are placed on the support members on the first and second racks, respectively. Driving the gear to rotate causes the two support members to move closer together, thus bringing the two power pipes closer together. Simultaneously, the pressing rod, as the racks move, presses against the limiting plate, causing the limiting plate to rotate, thereby swinging the two power pipes until they are aligned in a straight line, achieving precise alignment of the two power pipes.
[0004] Regarding the aforementioned technologies, when the outer diameter of the power pipe is smaller than the minimum distance between the two limiting plates in the width direction of the support plate, the movement of the extrusion rod cannot cause the limiting plates to come into contact with the power pipe, thus failing to achieve the function of swinging the two power pipes to keep them on the same straight line. This technology is not applicable to power pipes with smaller dimensions. Utility Model Content
[0005] To address the problem that existing technologies are not suitable for smaller-sized power pipes, this application provides a support structure for power construction.
[0006] The technical solution for a support structure used in power construction provided in this application is as follows:
[0007] A support structure for power construction includes a support frame, a first clamping block, a second clamping block, and a top pressing block. Rotating rollers are spaced apart along the length of the top of the support frame, and these rollers are rotatably connected to the support frame about its width. The first and second clamping blocks are slidably connected to the support frame relative to each other along its width. The support frame is equipped with a drive mechanism for synchronously driving the first and second clamping blocks closer together or further apart. A top frame is provided at the top of the support frame, and the top pressing block is slidably connected vertically to the top frame. The top frame is equipped with an adjustment mechanism for adjusting the height of the top pressing block. Two rollers are spaced apart and rotatably connected at the bottom of the top pressing block along the length of the support frame, and the top pressing block is equipped with a rotation mechanism for driving the two rollers to rotate in opposite directions.
[0008] By adopting the above technical solution, during power construction, two power pipes can be placed on rotating rollers at the top of the support frame. Since the rotating rollers are connected to the support frame and rotate around the width of the support frame, the cables can move flexibly on the rotating rollers. The drive mechanism can simultaneously drive the first clamping block and the second clamping block to slide relative to each other along the width of the support frame, so that they come closer together to clamp the cables and thus align the two power pipes. The adjustment mechanism can adjust the top pressure block to slide vertically on the top frame, changing the height of the top pressure block so that the roller at the bottom of the top pressure block contacts the cable. Then, the rotating mechanism drives the two rollers to rotate in opposite directions, thereby moving the cables on the rotating rollers to come closer until they abut, ultimately achieving the alignment and abutment of the cables, which facilitates the subsequent connection and installation of the two power pipes. The cooperation of the first clamping block, the second clamping block and the drive mechanism can achieve the alignment and abutment of power pipes of different sizes and specifications, improving the problem that the existing technology cannot be applied to smaller power pipes.
[0009] Optionally, the drive mechanism includes a double-ended lead screw and a handwheel. The double-ended lead screw is rotatably connected to the support frame about the width of the support frame. The two ends of the double-ended lead screw are respectively passed through the first clamping block and the second clamping block. The double-ended lead screw is threadedly connected to both the first clamping block and the second clamping block. The handwheel is connected to one end of the double-ended lead screw.
[0010] By adopting the above technical solution, turning the handwheel can drive the double-ended lead screw to rotate. Since the double-ended lead screw is threadedly connected to the first clamping block and the second clamping block, and the double-ended lead screw is rotatably connected to the support frame around the width direction of the support frame, when the double-ended lead screw rotates, the first clamping block and the second clamping block can slide relative to each other along the width direction of the support frame, realizing the synchronous movement of the two moving closer or further apart, which is convenient for clamping or releasing objects.
[0011] Optionally, the adjusting mechanism includes a threaded rod, a rotating block, and a return spring. The top frame has a vertically extending insertion hole, through which the threaded rod passes. The threaded rod is rotatably connected to the top pressure block around its own axis. The rotating block is rotatably connected to the top frame. One end of the return spring is connected to the rotating block, and the other end is connected to the top frame. The rotating block has a threaded groove on the side near the threaded rod, and the return spring tends to cause the threaded groove side of the rotating block to abut against the peripheral wall of the threaded rod.
[0012] By adopting the above technical solution, when it is necessary to adjust the height of the pressure block, rotating the rotating block overcomes the elastic force of the return spring, causing the threaded groove of the rotating block to separate from the threaded rod. At this time, the threaded rod can be moved up and down freely. Since the threaded rod is connected to the pressure block by rotating around its own axis, the height of the pressure block can be adjusted. After adjusting to the appropriate height, the rotating block is released, the return spring returns to its deformation, and the threaded groove side of the rotating block abuts against the peripheral wall of the threaded rod again. The threaded engagement locks the threaded rod, thereby fixing the height of the pressure block. This structure makes the height adjustment of the pressure block convenient, stable and reliable. Moreover, when the threaded groove side of the rotating block abuts against the peripheral wall of the threaded rod and is in a threaded connection state, rotating the threaded rod can drive the fine adjustment of the height of the pressure block, thereby making the pressure block clamping the power pipe more stable and reliable.
[0013] Optionally, the rotating mechanism includes a first gear, a second gear, a third gear, a fourth gear, and a power component. The first gear and the second gear are coaxially connected to two rollers, and the third gear and the fourth gear are rotatably connected to a top pressure block between the two rollers. The third gear meshes with the first gear and the fourth gear, and the fourth gear meshes with the second gear. The power component is used to drive the third gear to rotate.
[0014] By adopting the above technical solution, when the power component drives the third gear to rotate, the first gear and the fourth gear meshing with the third gear will rotate accordingly. Since the fourth gear meshes with the second gear, the second gear also begins to rotate. The first gear and the second gear are coaxially connected to the two rollers, thereby driving the two rollers to rotate in opposite directions. The structure is simple and compact, and easy to use.
[0015] Optionally, the power assembly includes a worm gear, a worm, and a handle. The worm gear is coaxially connected to a third gear, the worm is rotatably connected to a top pressure block, the worm meshes with the worm gear, and the handle is located at one end of the worm.
[0016] By adopting the above technical solution, turning the handle can drive the worm to rotate, and through the meshing transmission with the worm wheel, it drives the third gear to rotate, thereby driving the roller. Moreover, the worm wheel and worm gear transmission has self-locking properties, which can ensure the stability of the roller's rotation state, thus ensuring that the two power pipes are not easily separated when they come into contact, and improving the stability of the connection and installation of the two power pipes.
[0017] Optionally, the diameter of the middle part of the roller is smaller than the diameter of both ends, and a cushioning pad is provided on the peripheral wall of the roller.
[0018] By adopting the above technical solution, the diameter of the roller in the middle is smaller than that at both ends, which can better fit the two power pipes to be connected, enhance the pressure and rolling adjustment effect on the power pipes, and further improve the stability and flexibility of the support structure when connecting and installing the two power pipes; the setting of the buffer pad can reduce the pressure damage of the roller on the power pipe and increase the friction between the roller and the power pipe. Thus, the movement effect of the roller on the power pipe is improved.
[0019] Optionally, the support frame is provided with support legs at all four corners of the bottom. Each support leg includes a fixed cylinder and a movable rod. The fixed cylinder is connected to the support frame. The movable rod is inserted vertically into the fixed cylinder. A locking rod is inserted horizontally along the upper edge of the fixed cylinder. Multiple locking holes are spaced apart vertically along the upper edge of the movable rod. The locking rod is inserted into the locking holes.
[0020] By adopting the above technical solution, the stability of the support structure can be increased by setting support legs at the four corners of the bottom of the support frame. The support legs use a combination of a fixed cylinder and a movable rod. The movable rod can move vertically inside the fixed cylinder. In addition, the height of the support legs can be adjusted by inserting a locking rod into the locking holes at different heights of the movable rod to adapt to different construction ground conditions.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The drive mechanism synchronously drives the first clamping block and the second clamping block to move closer or further apart, which can flexibly adjust the spacing to adapt to the clamping and alignment requirements of power pipes of different specifications, and improves the problem that the existing technology cannot be applied to smaller power pipes; the cooperative arrangement of the rollers and the rotating mechanism on the top pressure block can make the two power pipes move closer to each other until they abut, which facilitates the subsequent connection and installation of the power pipes.
[0023] 2. The double-ended lead screw and handwheel configuration allows the double-ended lead screw to rotate by turning the handwheel, thereby causing the first clamping block and the second clamping block to move closer or further apart, thus achieving precise clamping, fixing, and alignment of power pipes of different specifications. The movement of the first clamping block and the second clamping block is stable and reliable, and the adjustment is convenient.
[0024] 3. The design of the worm gear, worm, and handle utilizes the self-locking characteristics of the worm and worm drive to achieve adjustment and instant locking of the roller's rotation in opposite directions, ensuring stable roller rotation. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a support structure for power construction. (Refer to...) Figure 1-2The power construction support structure includes a support frame 1, a first clamping block 2, a second clamping block 3, a top pressing block 4, a drive mechanism, an adjustment mechanism, and a rotating mechanism. Rotating rollers 11 are spaced along the length of the top of the support frame 1, and are rotatably connected to the support frame 1 about its width. The rotating rollers 11 are generally cylindrical and made of wear-resistant materials such as metal. The function of the rotating rollers 11 is to facilitate the sliding of the power pipe on the support frame 1 and reduce frictional resistance. Support legs 12 are provided at the four corners of the bottom of the support frame 1. Each support leg 12 includes a fixed cylinder 121 and a movable rod 122. The fixed cylinder 121 is connected to the support frame 1, and the movable rod 122 is vertically inserted into the fixed cylinder 121. A locking rod 123 is horizontally inserted into the fixed cylinder 121, and multiple locking holes 124 are vertically spaced on the movable rod 122, with the locking rod 123 inserted into the locking holes 124. The fixed cylinder 121 and the movable rod 122 are generally made of metal. By adjusting the length of the movable rod 122 inserted into the fixed cylinder 121 and locking it with the locking rod 123, the height of the support leg 12 can be adjusted to adapt to different ground conditions.
[0032] The first clamping block 2 and the second clamping block 3 are slidably connected to the support frame 1 along the width direction of the support frame 1. The first clamping block 2 and the second clamping block 3 are synchronously driven by the drive mechanism to move closer or further apart from each other. The first clamping block 2 and the second clamping block 3 slide on the support frame 1 through the cooperation of a sliding groove and a slider. For example, a T-shaped sliding groove is opened on the support frame 1, and a T-shaped slider is set at the bottom of the first clamping block 2 and the second clamping block 3 to match it. A top frame 5 is fixedly connected to the top of the support frame 1. Two vertical rods 41 are welded and fixed to the top of the top pressing block 4 along the vertical direction. Both vertical rods 41 are vertically inserted into the top frame 5, realizing the function of the top pressing block 4 slidingly connected to the top frame 5 along the vertical direction. The adjustment mechanism is used to adjust the height of the top pressing block 4. Two rollers 6 are spaced apart and rotatably connected to the bottom of the top pressing block 4 along the length direction of the support frame 1. The diameter of the middle part of the rollers 6 is smaller than the diameter of the two ends. This structural design can better limit the power pipe and prevent it from sliding left and right. A cushioning pad 61, made of rubber or plastic, is provided on the periphery of the roller 6 to increase friction with the power pipe. A rotating mechanism is mounted on the top pressure block 4 to drive the two rollers 6 to rotate in opposite directions.
[0033] In use, the two power pipes are placed on the rotating rollers 11 at the top of the support frame 1. The first clamping block 2 and the second clamping block 3 are simultaneously driven by the drive mechanism to slide relative to each other along the width of the support frame 1, bringing them closer together to clamp the power pipes and align them. Next, the adjusting mechanism adjusts the sliding of the top pressure block 4 vertically on the top frame 5, changing the height of the top pressure block 4 so that the roller 6 at the bottom of the top pressure block 4 abuts against the power pipe. Then, the rotating mechanism drives the two rollers 6 to rotate in opposite directions, causing them to pull the two power pipes closer together until their end faces abut. This achieves precise alignment and contact of the two power pipes, facilitating subsequent connection and installation, and improving the limitation of existing technologies for smaller power pipes.
[0034] For example, the drive mechanism includes a double-ended lead screw 13 and a handwheel 14. The double-ended lead screw 13 is rotatably connected to the support frame 1 about its width. Both ends of the double-ended lead screw 13 are respectively threaded onto the first clamping block 2 and the second clamping block 3, and the double-ended lead screw 13 is threadedly connected to both the first clamping block 2 and the second clamping block 3. The handwheel 14 is connected to one end of the double-ended lead screw 13. The double-ended lead screw 13 is generally made of metal, and its surface is machined with two sections of threads in opposite directions. The handwheel 14 is usually round for easy manual operation. When the handwheel 14 is rotated, the double-ended lead screw 13 rotates. Due to its threaded connection with the first clamping block 2 and the second clamping block 3, the first clamping block 2 and the second clamping block 3 can move synchronously closer or further apart. The movement of the first clamping block 2 and the second clamping block 3 is stable, enabling the clamping and fixing of single power tubes of different sizes and specifications, making it convenient to use.
[0035] Specifically, refer to Figure 1 The adjusting mechanism includes a threaded rod 51, a rotating block 52, and a return spring 53. A vertical insertion hole is provided on the top frame 5, through which the threaded rod 51 passes. The threaded rod 51 is rotatably connected to the top of the pressure block 4 around its own axis. The rotating block 52 is rotatably connected to the top of the top frame 5. One end of the return spring 53 is connected to the rotating block 52, and the other end of the return spring 53 is connected to the top frame 5. A threaded groove is provided on the side of the rotating block 52 near the threaded rod 51. The threaded groove is adapted to the thread of the threaded rod 51. The return spring 53 tends to make the side of the threaded groove of the rotating block 52 abut against the peripheral wall of the threaded rod 51, thereby making the threaded groove of the rotating block 52 and the threaded rod 51 achieve a threaded connection relationship. When the rotating block 52 is rotated to overcome the elastic force of the return spring 53 so that the rotating block 52 does not contact the threaded rod 51, the threaded rod 51 can be raised up and down to quickly adjust the height of the top pressure block 4; when the threaded groove of the rotating block 52 engages with the threaded rod 51, rotating the threaded rod 51 can finely adjust the height of the top pressure block 4, so that the top pressure block 4 can be stably pressed on the power pipe, which facilitates the connection of the two power pipes by rotating the rolling path to drive the power pipe to move along the length direction of the support frame 1.
[0036] For example, refer to Figure 3 The rotating mechanism includes a first gear 42, a second gear 43, a third gear 44, a fourth gear 45, and a power assembly. The first gear 42 and the second gear 43 are coaxially connected to two rollers 6, respectively. The third gear 44 and the fourth gear 45 are rotatably connected to a pressure block 4 between the two rollers 6. The first gear 42, the third gear 44, the fourth gear 45, and the second gear 43 mesh sequentially. The power assembly is mounted on the pressure block 4 and drives the third gear 44 to rotate. Driving the third gear 44 through the power assembly causes the first gear 42, the second gear 43, and the fourth gear 45 to rotate, thereby causing the two rollers 6 to rotate in opposite directions. This rotation of the two rollers 6 in opposite directions brings the electrical conduits they are abutting closer together, achieving the docking operation of the two electrical conduits. The coordinated arrangement of the first gear 42, the second gear 43, the third gear 44, the fourth gear 45, and the power assembly results in a simple structure, rapid and reliable power transmission, a compact structure, high space utilization, and reduced manufacturing costs.
[0037] Furthermore, the power assembly includes a worm gear 46, a worm 47, and a handle 48. The worm gear 46 is coaxially connected to the third gear 44, and the worm 47 is rotatably connected to the pressure block 4. The worm 47 meshes with the worm gear 46, and the handle 48 is located at one end of the worm 47. When the handle 48 is turned, the worm 47 drives the worm gear 46 to rotate, thereby driving the third gear 44 to rotate. The worm gear 46 and the worm 47 have a self-locking function, which can ensure the stability of the rotation of the roller 6. When the two power pipes are in contact, the two power pipes will be in contact without turning the handle 48, which facilitates the subsequent connection and installation of the two power pipes.
[0038] The implementation principle of the power construction support structure in this application embodiment is as follows: When in use, the two power pipes that need to be connected and installed are placed directly on the rotating roller 11 on the support frame 1. The handwheel 14 is rotated to drive the double-headed screw 13 to rotate, which drives the first clamping block 2 and the second clamping block 3 to approach each other until they are pressed against the two sides of the two power pipes to form a clamping and fixing. At this time, the two power pipes are in an aligned state. Next, rotating the rotating block 52 causes the threaded groove on the rotating block 52 to engage with the threaded rod 51. Rotating the threaded rod 51 adjusts the vertical lifting of the top pressure block 4, causing the two rollers 6 on the top pressure block 4 to press against one of the power pipes respectively. At this time, rotating the handle 48 drives the worm gear 47 to rotate, which in turn drives the worm wheel 46 to rotate, thereby driving the third gear 44 to rotate. Through the meshing transmission of the first gear 42, the second gear 43, the third gear 44, and the fourth gear 45, the first gear 42 and the second gear 43 rotate in opposite directions, thereby driving the two rollers 6 to rotate in opposite directions. Through the friction between the rollers 6 and the power pipes, the two power pipes are driven to approach each other until they abut. This completes the alignment and docking of the two power pipes, improving the problem of the existing technology being unable to apply to smaller power pipes.
[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
