Description

Technical Field

[0001] This utility model relates to the field of high-altitude construction hoisting equipment technology, specifically a pole lifting structure. Background Technology

[0002] Due to the different structures of various towers, and the varying terrain, geological conditions, transportation routes, and specific conditions of the construction units surrounding the towers, tower erection methods can be divided into two main categories: integral erection and disassembly erection. Towers, due to terrain and weight factors, are mostly erected using the disassembly method. For towers that are tall, heavy, in complex terrain, and have large bases, gantry erection is preferable. The gantry, as the core equipment of the high-altitude construction platform, is mainly used to support and hoist various parts of the tower. It achieves luffing through electrically driven trolleys on both sides of the boom, and the gantry head can rotate electrically in both directions, ensuring a complete working area without blind spots. The gantry rests directly on the ground and achieves self-raising and self-lowering through a hydraulic jacking system, simplifying operation and reducing safety risks. Introducing / extracting standard sections from the ground transforms traditional high-altitude gantry operations into ground-based operations, with the operator manning the gantry from the ground and monitoring the operation through a video system, further reducing safety risks.

[0003] Patent application number CN202221424537.7 discloses a tower erecting jacking device, including a base, a jacking frame fixed on the base, two sets of hydraulic cylinders symmetrically arranged at both ends of the jacking frame, all of which are fixed to the base. A jacking support is fixed to the upper end of the two sets of hydraulic cylinders. The jacking support includes a sliding frame, a pulley assembly, and a hook plate assembly. A pulley assembly is fixed to each wall surface of the sliding frame. The pulley assembly includes a pulley seat and a pulley. The pulley seat is connected to the sliding frame... The frame is fixedly connected, and the pulley is rotatably connected to the pulley seat via a pin. The pulley abuts against the outer wall of the lifting frame. The hook plate assembly includes a hook plate, a hook plate seat, and a counterweight. The hook plate seat is fixedly connected to the lower part of the sliding frame, and the hook plate is rotatably connected to the hook plate seat via a pin. A hook is provided at the end of the hook plate away from the lifting frame, and the counterweight is detachably connected to the hook. This utility model uses the cooperation of two sets of symmetrical hydraulic cylinders and the hook plate assembly to move the lifting platform up and down, thereby lifting the main body of the boom composed of standard sections. However, for the hook plate assembly to achieve its working effect, it must be equipped with a counterweight. The exposed counterweight is at high altitude and subject to strong winds. When the upward or lateral wind force exceeds its weight, the hook plate assembly loses its function. The hook plate assembly cannot provide the necessary limiting effect for the boom, causing the entire high-altitude equipment to go out of control and resulting in a major accident. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pole lifting structure that can achieve stable lifting of the pole through structural optimization and improvement.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A jacking structure includes a jacking frame mounted on a high-altitude construction platform and a jacking rod sleeved within the jacking frame. The jacking rod is composed of at least one unit rod directly or sleeved together. The jacking frame includes:

[0007] A sliding crossbar, the two ends of which are connected to end mounting kits;

[0008] The end mounting kit includes a sleeve, a mating part, and a back connecting part. The sleeve and the mating part are connected through the back connecting part. The sleeve is connected to the end of the sliding crossbeam. The sleeve is provided with a cylinder mounting hole. The gap between the sleeve and the mating part forms a sliding space. The unit rod passes through the sliding space and can move up and down in the sliding space.

[0009] A hook assembly includes a mounting bracket and a rotating hook. The rotating hook is mounted on the mounting bracket above the sleeve or the mating part via a pin. The rotating hook includes an insertion block protruding toward the unit rod. When the insertion block is in a fixed position, it is inserted into the unit rod and connected to the unit rod.

[0010] The unit rod includes a housing and a first horizontal plate and a second horizontal plate disposed in the inner cavity. The rotating hook is connected to the housing, the first horizontal plate, or the second horizontal plate in different states.

[0011] As a preferred embodiment of the present invention, the bottom of the rotating hook includes a horizontal surface contact. When the horizontal surface contact is in the limited position, it is connected to the top surface of the sleeve or the mating part. The rotating hook is provided with an upward rotation limiting slope in the direction away from the unit rod on the horizontal surface contact. When the upward rotation limiting slope is connected to the top surface of the sleeve or the mating part, the insertion block rotates out from the unit rod and connects to the outer shell.

[0012] As a preferred embodiment of the present invention, the rotating hook is provided with a rounded corner in the direction of contact with the unit rod on the horizontal plane, and the top of the rounded corner is provided with a transition slope that is inclined upward. When the transition slope is connected to the top surface of the sleeve or the mating part, the rotating hook is in the gap between the first horizontal plate and the second horizontal plate.

[0013] The transition slope is inclined upward and has a fitting slope. When the fitting slope is connected to the sleeve or the mating part, the distance from the end corner of the insertion block to the outer shell is greater than or equal to zero.

[0014] As a preferred embodiment of the present invention, the outer width of the outer shell is smaller than the width of the sliding space.

[0015] As a preferred embodiment of the present invention, the sleeve portion and the mating portion are provided with anti-collision baffles facing the unit rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By designing the end-mounting kit, a pair of rotating hooks that are shaft-connected to the mounting frame are respectively located on the sleeve part and the mating part of the end-mounting kit. The rotating hooks on both sides work together with the unit rod to add unit rods, thereby changing the length of the pole and ultimately achieving the lifting and lowering of the entire construction platform.

[0031] See attached document Figure 1 To be continued Figure 5 As shown, a pole lifting structure includes a lifting frame 1 installed on a high-altitude construction platform and a pole 2 sleeved in the lifting frame 1. The pole 2 is composed of at least one unit pole 201 directly or sleeved together. The lifting frame 1 includes a sliding crossbar 3, an end mounting kit 4, and a hook assembly 5.

[0032] The two ends of the sliding crossbar 3 are connected to the end mounting kit 4.

[0033] The end mounting kit 4 includes a sleeve part 401, a mating part 402, and a back connecting part 403. The sleeve part 401 and the mating part 402 are connected by the back connecting part 403. The recessed space between the middle sleeve part 401 and the mating part 402 is a sliding space 400. The entire construction platform moves up and down with the extension and retraction of the hydraulic cylinder 7. The support rod 2 can move up and down in the sliding space 400 with the movement of the construction platform. The sleeve part 401 is connected to the end of the sliding crossbar 3. The sleeve part 401 is provided with a cylinder mounting hole 4011. The sliding crossbar 3 is also provided with a mating notch 301 corresponding to the cylinder mounting hole 4011 for installing and fixing the hydraulic cylinder. The gap between the sleeve part 401 and the mating part 402 forms the sliding space 400. The unit rod 201 passes through the sliding space 400 and can move up and down in the sliding space 400.

[0034] The hook assembly 5 includes a mounting bracket 501 and a rotating hook 502. The rotating hook 502 is connected to the mounting bracket 501 via a pin 503, and is positioned above the sleeve portion 401 or the mating portion 402. The rotating hook 502 can rotate around the pin 503 in a vertical plane. The rotating hook 502 includes an insertion block 5021 protruding towards the unit rod 201. When the insertion block 5021 is in a fixed position, it is inserted into and connected to the unit rod 201. The unit rod 201 can be raised or lowered by rotating the insertion block 5021 into and out of the unit rod 201, thereby adding the unit rod 201.

[0035] The unit rod 201 includes a housing 2011 and a first horizontal plate 2012 and a second horizontal plate 2013 disposed in the inner cavity. The rotating hook 502 is connected to the housing 2011, the first horizontal plate 2012, or the second horizontal plate 2013 in different states.

[0036] The bottom of the rotating hook 502 includes a horizontal surface contact 5022. When the horizontal surface contact 5022 is in the limited position, it is connected to the top surface of the sleeve part 401 or the mating part 402. The rotating hook 502 is provided with an upward rotation limiting slope 5023 in the direction away from the unit rod 201 of the horizontal surface contact 5022. When the upward rotation limiting slope 5023 is connected to the top surface of the sleeve part 401 or the mating part 402, the insertion block 5021 rotates out from the unit rod 201 and connects to the outer shell 2011.

[0037] The rotating hook 502 has a rounded corner 5024 in the direction of contact 5022 on the horizontal plane near the unit rod 201. The top of the rounded corner 5024 is inclined upward and has a transition slope 5025. When the transition slope 5025 is connected to the top surface of the sleeve part 401 or the mating part 402, the rotating hook 502 is in the gap between the first horizontal plate 2012 and the second horizontal plate 2013.

[0038] The transition slope 5025 is inclined upward and has a fitting slope 5026. When the fitting slope 5026 is connected to the sleeve part 401 or the mating part 402, the distance from the end corner 50212 of the insertion block 5021 to the outer shell 2011 is greater than or equal to zero.

[0039] The outer width of the outer casing 2011 is less than the width of the sliding space 400.

[0040] The sleeve part 401 and the mating part 402 are provided with anti-collision baffles 6 facing the unit rod 201.

[0041] The working principle of this utility model:

[0042] In the initial position, a pair of rotating hooks 502 are inserted into the unit rod 201, with the top surface of the rotating hooks 502 contacting the first horizontal plate 2012. The hydraulic cylinder 7 is activated to extend, and the sliding crossbar 3, fixedly connected to the hydraulic cylinder, moves upward following the cylinder. Then, the next unit rod 201 is added below the already raised unit rod 201. The hydraulic cylinder 7 is then retracted, causing the sliding crossbar 3 to move downward. The subsequent unit rod 201 moves upward relative to the sliding crossbar 3, moving upward from the first horizontal plate 2012 and second horizontal plate 2013 of the previous unit rod 201. This causes the rotating hooks 502 to rotate in a circular motion away from the unit rod 201. When the limiting inclined surface 5023 rotates to connect with the top surface of the sleeve part 401 or the mating part 402, the insertion block 5021 rotates out from the unit rod 201 and connects with the outer shell 2011. The distance from the end corner 50212 of the insertion block 5021 to the outer shell 2011 is zero. The sliding crossbar 3 continues to move downward. The sliding inclined surface 5027 slides and rubs against the outer shell 2011. When the sliding inclined surface 5027 contacts the first horizontal plate 2012 of the next unit rod 201, the rotating hook 502 moves towards the inner cavity of the unit rod 201 under the influence of gravity and downward friction and is inserted into the unit rod 201. When the top surface of the rotating hook 502 contacts and abuts against the first horizontal plate 2012, the unit rod 201 is stably fixed.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
