Description

Technical Field

[0001] This utility model relates to the field of tower segment construction, and in particular to a hanging construction device for tower segments. Background Technology

[0002] In new energy projects, the splicing of tunnel segments in hybrid tower construction is a critical construction step, and its safety and efficiency have a vital impact on the progress of the entire project. However, during the construction process, the operation of slings and rigging for high-altitude work is difficult for construction workers. When installing and dismantling slings and rigging for tunnel segments, construction workers often have to perform complex and dangerous operations at height. Due to the lack of suitable tools and stable working platforms, the installation and dismantling of slings and rigging is inefficient and prone to insecure installation, affecting the safety and stability of tunnel segment hoisting. At the same time, the safety risks for workers walking on the smooth surface of the tunnel segments are high. Without effective safety protection measures, construction workers are prone to slipping, falling, and other accidents, seriously threatening their lives and adversely affecting the progress and quality of the project. Therefore, a tower segment hanging construction device is proposed to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a suspended construction device for tower segments, which solves the problems of low efficiency, unstable installation affecting hoisting safety, and easy slipping and falling of personnel on smooth segments due to lack of effective protection, which threaten life safety and affect project progress and quality in the high-altitude operation of existing segments.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tower segment hanging construction device, including a device body that can be hooked on the top of the segment. The device body includes a manned frame with an open top. Two sleeves are symmetrically arranged on the top of the manned frame. A telescopic frame is telescopically arranged in the two sleeves. A hook frame extending downward is arranged at the front end of the telescopic frame. The device body is hooked on the top of the segment through the gap formed between the hook frame and the manned frame. Anti-slip wheels are provided on the bottom of the hook frame and the manned frame opposite to each other, and the bottom of the telescopic frame. A drive mechanism for controlling the extension and retraction of the telescopic frame is also provided on the back of the manned frame.

[0005] In the preferred embodiment, the telescopic frame has grooves at the bottom of the side arms of the two sleeves, and a rack is installed in the grooves.

[0006] In the preferred embodiment, the drive mechanism includes two bearing seats symmetrically arranged on the back of the manned frame, a rotating rod rotatably arranged between the two bearing seats, two drive gears mounted on the outside of the rotating rod, the two drive gears meshing with two racks respectively, one end of the rotating rod passing through the bearing seat and connected to an adjustment handle, and a ratchet assembly for locking is also provided between the outside of one of the bearing seats and the rotating rod.

[0007] In a preferred embodiment, the ratchet assembly includes a ratchet disposed outside the rotating rod and a pawl assembly disposed outside the bearing housing. The pawl assembly includes a swivel bearing disposed outside the bearing housing, a rotating shaft rotatably disposed on the swivel bearing, a pawl that cooperates with the ratchet disposed outside the rotating shaft, a spring piece that fits against the outside of the pawl disposed outside the bearing housing, and a paddle piece disposed outside the rotating shaft.

[0008] In the preferred embodiment, a tool hook is provided on the outside of the lever.

[0009] In the preferred embodiment, the telescopic frame is also equipped with a reinforcing crossbeam located at the anti-slip wheel.

[0010] In the preferred embodiment, an anti-slip pad is provided on the inner bottom wall of the device body.

[0011] This utility model provides a tower segment hanging construction device. The device body can be hooked onto the top of the segment by creating a gap between the hook frame and the personnel carrier, thus providing a convenient construction platform for workers on top of the segment. This avoids workers having to use slings for high-altitude work, effectively improving construction safety and flexibility. The gap between the hook frame and the personnel carrier can be adjusted via a drive mechanism to accommodate segments of different thicknesses, while also providing clamping force. Through the hook frame, personnel carrier, and telescopic frame, anti-slip wheels connect to the three surfaces of the segment, ensuring clamping force while allowing the device body to move on the segment to adjust its position, thus preventing workers from walking directly on top of the segment.

Detailed Implementation

[0022] like Figure 1-8 As shown, a tower segment hanging construction device includes a device body 1 that can be hooked onto the top of the segment 2, thereby providing construction workers with a convenient platform for construction.

[0023] The device body 1 includes a manned frame 10 with an open top, which facilitates the entry and standing of construction personnel. Two sleeve rods 11 are symmetrically arranged on the top of the manned frame 10. The sleeve rods 11 are hollow inside and open at both ends. Telescopic frames 12 are telescopically arranged in the two sleeve rods 11. The front end of the telescopic frame 12 is provided with a downward-extending hook frame 13. The telescopic frame 12 and the hook frame 13 form a sideways "L" shaped structure, and both are frame structures. The device body 1 is hooked to the top of the pipe segment 2 through the gap formed between the hook frame 13 and the manned frame 10. Anti-slip wheels 14 are provided on the bottom of the hook frame 13 and the manned frame 10 on opposite sides, and on the bottom of the telescopic frame 12. A drive mechanism 16 for controlling the extension and retraction of the telescopic frame 12 is also provided on the back of the manned frame 10.

[0024] With this design, the distance between the hook frame 13 and the personnel carrier 10 can be adjusted by the drive mechanism 16 to match the thickness of the pipe segment 2, thereby clamping the pipe segment 2 and hooking the device body 1 onto the top of the pipe segment 2. At the same time, the hook frame 13, the personnel carrier 10 and the telescopic frame 12 are all in contact with the three surfaces of the pipe segment 2 through anti-slip wheels 14, so that the device body 1 can slide on the pipe segment 2 while meeting the hooking conditions, thereby adjusting the construction position and providing a movable construction platform for construction personnel on the pipe segment 2.

[0025] It should be noted that during installation, it is necessary to ensure that the anti-slip wheel 14 is in full contact with the surface of the segment 2 to clamp it, thereby providing sufficient friction and clamping force.

[0026] In addition, to further improve construction safety, construction workers can attach their safety belt hooks to the device body 1 when carrying out construction work.

[0027] In this embodiment, the manned frame 10 specifically includes a base plate 101, with uprights 102 provided at the four corners of the top of the base plate 101, and protective rods 103 provided between the four uprights 102. The top of the uprights 102 is also provided with connecting rods 104 perpendicular to the two sleeve rods 11.

[0028] In the preferred embodiment, the telescopic frame 12 has grooves 120 at the bottom of the side arms of the two sleeve rods 11, and a rack 121 is provided in the grooves 120. Placing the rack 121 in the grooves 120 can prevent it from affecting the normal telescopic extension and retraction of the telescopic frame 12.

[0029] In the preferred embodiment, the drive mechanism 16 includes two bearing seats 160 symmetrically arranged on the back of the manned frame 10. A rotating rod 161 is rotatably arranged between the two bearing seats 160 via a bearing. Two drive gears 162 are mounted on the outside of the rotating rod 161. The two drive gears 162 mesh with two racks 121 respectively. One end of the rotating rod 161 passes through the bearing seat 160 and is connected to an adjustment handle 163.

[0030] With this design, the rotating rod 161 and the drive gear 162 can be rotated by rotating the adjustment handle 163, and then the rack 121 can be used to drive the telescopic frame 12 to extend and retract, thereby achieving the effect of adjusting the distance between the hook frame 13 and the personnel carrier frame 10.

[0031] One of the bearing housings 160 is provided with a ratchet assembly 164 for locking between the outside of the bearing housing 160 and the rotating rod 161. The ratchet assembly 164 can effectively prevent loosening during the hooking process and prevent the device body 1 from falling off.

[0032] In a preferred embodiment, the ratchet assembly 164 includes a ratchet 1640 disposed outside the rotating rod 161 and a pawl assembly disposed outside the bearing housing 160. The pawl assembly includes a rotary bearing 1641 disposed outside the bearing housing 160. A rotating shaft 1642 is rotatably disposed on the rotary bearing 1641. A pawl 1643 that cooperates with the ratchet 1640 is disposed outside the rotating shaft 1642. A spring piece 1644 that fits against the outside of the pawl 1643 is also disposed outside the bearing housing 160. The spring piece 1644 can keep the pawl 1643 in contact with the ratchet 1640, thereby preventing the distance between the hook frame 13 and the personnel carrier 10 from changing due to the reverse rotation of the rotating rod 161.

[0033] A lever 1645 is also provided on the outer side of the pivot 1642, which makes it easy to disengage the pawl 1643 from the ratchet 1640 by pressing the lever 1645 when removing the device body 1, thereby allowing the handle 163 to be reversed to widen the distance between the hook frame 13 and the personnel carrier 10, and to remove the device body 1.

[0034] In the preferred embodiment, the sleeve rod 11 is provided with a tool hook 18 on the outside, which makes it easy to hook the corresponding construction tools on it.

[0035] In a preferred embodiment, the telescopic frame 12 is further provided with a reinforcing crossbeam 122 located at the anti-slip wheel 14, thereby enhancing the structural strength of the telescopic frame 12.

[0036] In the preferred embodiment, an anti-slip pad 105 is provided on the inner bottom wall of the device body 1 to prevent construction workers from slipping.

[0037] In addition, since the main body 1 of the device is a frame structure, stiffening blocks are provided at all corners of the structure.

[0038] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
