Description

Technical Field

[0001] This invention relates to the field of fixing device technology, specifically a fixing device for installing utility poles. Background Technology

[0002] In our daily lives, the power lines used by residents are generally installed on the outside of utility poles. During installation, to reduce risks and save manpower, fixing devices are typically used to secure the poles, effectively minimizing the risk of accidental injuries. However, some fixing devices used for utility pole installation have certain defects in their use, such as: The invention disclosed in CN110836039B is a utility pole installation device. The device, through its main structure of a base plate, a pole fixing device, a rotating device, a flange fixing device, a power device, and a limiting block, solves the problems of safety hazards caused by the instability of the pole due to human support and the need for multiple people to work together to install the pole during the traditional manual pole erection process. In the aforementioned document, the first and second half-rings are limited by a U-shaped block, and one end of the rotating block is rotatably connected to the top of the fixed block via a fixed shaft. The two ends of the utility pole are located between the first and second half-rings and the rotating and fixed blocks, respectively, and the distance between the first and second half-rings and the rotating and fixed blocks remains constant. This means that the device can only be installed on utility poles of the same size, resulting in certain limitations in its use.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on the existing fixed device structure. Summary of the Invention

[0004] The purpose of this invention is to provide a fixing device for installing utility poles, in order to solve the problem mentioned in the background art where the distance between the first and second half-rings and the rotating block and the fixing block remains constant, which limits the device to installation only on utility poles of the same size, resulting in certain limitations in its use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fixing device for installing utility poles, comprising a support plate, rollers, and upright plates. Rollers are rotatably mounted on the lower end of the support plate, and two sets of upright plates are fixedly mounted inside the support plate. A movable groove is formed on one side of the upright plate near the middle of the support plate, and a connecting block is slidably mounted inside the movable groove. A contact plate is rotatably mounted on the end of the connecting block away from the movable groove, and an installation groove is formed inside the contact plate. A sliding plate is slidably mounted inside the installation groove, and a ball bearing is nested on the outer side of the sliding plate. A limiting groove is formed on the right side of the movable groove via the upright plate, and a return spring is fixedly mounted inside the limiting groove. A moving block is fixedly mounted on the upper end of the return spring, and a lower arc block is rotatably mounted inside the moving block. Two sets of screws are threaded through the lower arc block. The screw is fitted with an upper arc block on its outer side, and the upper arc block is located above the lower arc block. Connecting parts are fitted on the outer sides of the lower arc block and the connecting block. Two sets of fixing plates are fixedly installed on the upper end of the support plate, and a rotating rod is rotatably installed inside the fixing plate. A support member is fixedly installed at the upper end of the rotating rod. Two sets of rotating parts are fixedly installed on the left side of the rotating rod, and a first limiting block is rotatably installed inside the two sets of rotating parts. A second limiting block is fixedly installed at the upper end of the first limiting block by bolts. A motor is fixedly installed on the side of the fixing plate away from the support member, and a fixing frame is fixedly installed on the side of the fixing plate close to the support member. A winding wheel is rotatably installed inside the fixing frame, and a steel wire rope is wound around the outside of the winding wheel. The end of the steel wire rope away from the winding wheel is fixedly connected to the rotating part. A traction member is fixedly installed on the right side of the support plate.

[0006] Preferably, a fixing block is fixedly installed on the side of the fixing plate near the support member, and a connecting groove is formed on the side of the fixing plate near the support member. A positioning block is slidably installed inside the connecting groove, and a traction rope and a support spring are fixedly installed on the side of the positioning block near the connecting groove. A sliding groove is formed on the side of the fixing plate away from the support member, and a slider is slidably installed inside the sliding groove. By setting the fixing block and the positioning block, the rotating part can be effectively positioned, thereby ensuring the verticality of the falling utility pole.

[0007] Preferably, the connecting block forms a sliding structure with the upright plate through the movable groove, and two sets of connecting blocks and movable grooves are symmetrically arranged about the vertical central axis of the support plate. The sliding structure formed by the connecting block and the upright plate through the movable groove allows the connecting block to slide inside the upright plate through the movable groove.

[0008] Preferably, the slide plate forms a sliding structure with the contact plate through ball bearings and mounting grooves, and two sets of mounting grooves and contact plates are symmetrically arranged about the vertical central axis of the support plate. The sliding structure formed by the slide plate with the contact plate through ball bearings and mounting grooves allows the ball bearings to rotate during the sliding process inside the mounting groove, thereby effectively reducing the friction force on the slide plate during movement.

[0009] Preferably, the moving block forms an elastic structure with the upright plate through a return spring, and the moving block forms a sliding structure with the upright plate through a limiting groove. The elastic structure formed by the moving block with the upright plate through the return spring can push the moving block to slide inside the upright plate.

[0010] Preferably, both the lower and upper arc blocks are threadedly connected to the screw, and two sets of screws are symmetrically arranged about the vertical central axis of the lower arc block. The threaded connection between the lower and upper arc blocks and the screw allows the lower and upper arc blocks to be limited and fixed to the outside of utility poles of different sizes through the screw.

[0011] Preferably, the side view of the first limiting block and the second limiting block that are close to each other is an arc-shaped structure, and the two ends of the first limiting block are respectively rotatably connected to the rotating member. The fact that the side view of the first limiting block and the second limiting block that are close to each other is an arc-shaped structure allows the first limiting block and the second limiting block to limit the outer side of the utility pole of different sizes as they approach each other.

[0012] Preferably, the positioning block forms a sliding structure with the fixing plate through the connecting groove, and the positioning block forms an elastic structure with the fixing plate through the support spring. The positioning block forms a sliding structure with the fixing plate through the connecting groove, and the support spring can push the positioning block to slide inside the connecting groove.

[0013] Preferably, the slider forms a sliding structure with the fixed plate through the slide groove, and the slider forms a traction structure with the positioning block through the traction rope. Furthermore, two sets of sliders, slide grooves, and positioning blocks are symmetrically arranged about the vertical central axis of the support plate. The slider forming a sliding structure with the fixed plate through the slide groove allows the positioning block to move by the traction rope during the sliding process inside the slide groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This utility pole installation fixing device, during the installation process, places the utility pole on the upper end of the lower arc block and then uses a screw to install the upper arc block on the upper end of the lower arc block, thus fixing the utility pole inside the device. Then, the motor operates and drives the winding wheel to rotate, which in turn causes the rotating component to rotate the utility pole via a wire rope. During this process, the left side of the utility pole remains in contact with the contact plate. When the rotating component rotates the utility pole to a vertical position, the screw is rotated to separate the upper arc block from the utility pole. At this point, the sliding plate is disengaged from the contact plate, causing the contact plate to rotate and the utility pole to fall into the pit. This completes the utility pole fixing installation process. By adjusting the distance between the lower and upper arc blocks and the first and second limiting blocks, the device can install utility poles of different sizes, effectively improving its applicability. 2. In this utility pole installation fixing device, during the process of the rotating component driving the utility pole to a vertical position, the rotating component contacts and presses against the positioning block. After being pressed, the positioning block moves into the connecting groove, compressing the support spring. After the rotating component contacts the fixing block, the support spring expands and pushes the positioning block to its initial position. At this point, the rotating component can make the utility pole vertical and install it. After the utility pole is installed, the user pushes the slider to slide inside the groove. During this process, the slider will drive the positioning block into the connecting groove through the traction rope. At this time, the two sets of motors work to make the rotating component move to its initial position. This completes the process of limiting the vertical position of the rotating component, thereby enabling the utility pole to be installed vertically and improving the practicality of the device for utility pole installation.

Two sets of screws 12 are installed through the lower arc block 11, and an upper arc block 13 is sleeved on the outer side of each screw 12, with the upper arc block 13 located above the lower arc block 11. A connecting piece 14 is sleeved on the outer side of the lower arc block 11 and the connecting block 5. Two sets of fixing plates 16 are fixedly mounted on the upper end of the support plate 1, and a rotating rod 17 is rotatably mounted inside each fixing plate 16. A support piece 18 is fixedly mounted on the upper end of the rotating rod 17. Two sets of rotating parts 19 are fixedly mounted on the left side of the rotating rod 17, and a first limiting block 20 is rotatably mounted inside each of the two sets of rotating parts 19. A second limiting block 21 is fixedly installed on the upper end of the first limiting block 20 by bolts. A motor 22 is fixedly installed on the side of the fixing plate 16 away from the support member 18, and a fixing frame 23 is fixedly installed on the side of the fixing plate 16 close to the support member 18. A winding wheel 24 is rotatably installed inside the fixing frame 23, and a steel wire rope 25 is wound around the outside of the winding wheel 24. The end of the steel wire rope 25 away from the winding wheel 24 is fixedly connected to the rotating member 19. A traction member 34 is fixedly installed on the right side of the support plate 1. The connecting block 5 forms a sliding structure with the vertical plate 3 through the movable groove 4, and the connecting block 5 and the movable groove 4 are symmetrical about the vertical central axis of the support plate 1. Two sets are provided. The sliding plate 6 forms a sliding structure with the contact plate 15 through the ball bearing 7 and the mounting groove 33. The mounting groove 33 and the contact plate 15 are symmetrically arranged in two sets about the vertical central axis of the support plate 1. The moving block 10 forms an elastic structure with the upright plate 3 through the return spring 9. The moving block 10 forms a sliding structure with the upright plate 3 through the limiting groove 8. The lower arc block 11 and the upper arc block 13 are both threadedly connected to the screw 12.

The side view of the first limiting block 20 and the second limiting block 21 that are close to each other is an arc-shaped structure. The two ends of the first limiting block 20 are respectively rotatably connected to the rotating part 19.

[0020] according to Figure 1-6When using this pole installation fixing device, first place the device at the desired location. Before installing the pole, the pole needs to be fixed inside the device. During this process, the user needs to use a crane to place the pole on top of the device. At this point, the pole will be positioned above the lower arc block 11, the support member 18, and the first limiting block 20. Then, the user can align the upper arc block 13 with the lower arc block 11 and use screws 12 to ensure a tight fit between them. The upper arc block 13 and lower arc block 11 will then be in close contact with the outer side of the pole. Finally, the user uses bolts to align the second limiting block 21 with the pole. The upper end of the first limiting block 20 is positioned so that it is tightly fitted to the utility pole but not in contact with it. The end of the utility pole near the upper arc block 13 contacts the left side of the contact plate 15. At this point, the user can activate both sets of motors 22. During operation, the motors 22 drive the winding wheel 24 via their output shafts. The rotation of the winding wheel 24 causes the wire rope 25 to wind up. Simultaneously, the rotating component 19 rotates around the rotating rod 17, causing the utility pole to rotate. During the rotation of the rotating component 19, the moving block 10 moves downwards inside the limiting groove 8, causing the return spring 9 to contract. The lower arc block 11... The pole will rotate inside the moving block 10. At this time, the connecting block 5 will slide inside the movable groove 4 through the contact plate 15. When the rotating part 19 rotates the pole to a vertical position, the two sets of motors 22 will stop working. At this time, the connecting block 5 and the moving block 10 will move to the bottom of the movable groove 4 and the limiting groove 8 respectively. The left side of the rotating part 19 will contact the fixed block 26. At this time, the user will rotate the screw 12 to separate the upper arc block 13 from the pole, but will not remove the screw 12 from the lower arc block 11. At this time, the pole will be supported by the weight of the contact plate 15 and the sliding plate 6. The user can then use the handle to move the sliding plate 6 from the contact plate 10. When the contact plate 15 is pulled out, it rotates on the outside of the connecting block 5, and the utility pole falls from the top of the device into the pre-dug pit. During this process, the lower arc block 11 and the upper arc block 13 are connected to the first limiting block 20 and the second limiting block 21, which can limit the falling position of the utility pole, thus ensuring that the utility pole falls vertically. This completes the process of fixing and installing the utility pole. By adjusting the distance between the lower arc block 11 and the upper arc block 13 and the first limiting block 20 and the second limiting block 21, the device can be used to install utility poles of different sizes, thereby effectively improving the applicability of the device.

[0021] A fixing block 26 is fixedly installed on the side of the fixing plate 16 near the support member 18, and a connecting groove 27 is opened on the side of the fixing plate 16 near the support member 18. A positioning block 28 is slidably installed inside the connecting groove 27, and a traction rope 29 and a support spring 30 are fixedly installed on the side of the positioning block 28 near the connecting groove 27. A sliding groove 31 is opened on the side of the fixing plate 16 away from the support member 18, and a slider 32 is slidably installed inside the sliding groove 31. The positioning block 28 forms a sliding structure with the fixing plate 16 through the connecting groove 27, and the positioning block 28 forms an elastic structure with the fixing plate 16 through the support spring 30. The slider 32 forms a sliding structure with the fixing plate 16 through the sliding groove 31, and the slider 32 forms a traction structure with the positioning block 28 through the traction rope 29. Two sets of slider 32, sliding groove 31 and positioning block 28 are symmetrically arranged about the vertical central axis of the support plate 1.

[0022] according to Figure 1-2 and Figure 7-9 During the rotation of the rotating component 19, it contacts and presses against the positioning block 28. The positioning block 28, after being pressed, moves into the connecting groove 27, causing the support spring 30 to contract. When the rotating component 19 contacts the fixed block 26, the compressed support spring 30 expands and pushes the positioning block 28 to its initial position. At this time, the fixed block 26, in conjunction with the positioning block 28, limits the rotation of the rotating component 19, thus keeping the utility pole inside the device in a vertical position. After the utility pole is installed, the user pushes... The two sets of sliders 32 slide downward inside the groove 31. During this process, the sliders 32 will cause the positioning block 28 to move into the connecting groove 27 through the traction rope 29. After the positioning block 28 has completely moved into the connecting groove 27, the user can make the two sets of motors 22 work and drive the winding wheel 24 to rotate in the opposite direction. At this time, the rotating part 19 will move to the initial position. This completes the process of limiting the vertical state of the rotating part 19, thereby enabling the utility pole to be installed vertically, improving the practicality of the device for utility pole installation and increasing the overall usability.
