Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, and in particular to an anti-climbing device for tower cranes with independent free height. Background Technology

[0002] Currently, there are various types of tower crane anti-climbing devices on the market, including welded guardrails and detachable guardrails. Welded guardrails are usually welded and fixed to the tower crane's climbing frame or standard sections, and their fixed position after installation makes it difficult to adapt to changes in the independent free height and size of the tower crane at different construction stages. While detachable guardrails solve the installation flexibility problem to some extent, in actual use, there is a risk that the guardrails can be easily opened or damaged by people, which greatly reduces the anti-climbing effect. Some anti-climbing devices have defects in their protective design, such as excessively large spacing between guardrails, which cannot effectively prevent small people from passing through, and cannot fundamentally eliminate the safety hazard of unauthorized personnel climbing into the tower crane, making it difficult to ensure the safety of the construction site. Therefore, we have launched an independent free height tower crane anti-climbing device. Utility Model Content

[0003] The main purpose of this utility model is to provide an independent, free-height anti-climbing device for tower cranes, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An independent free-height tower crane anti-climbing device includes a tower crane base, a tower crane frame fixedly connected to the upper middle part of the tower crane base, an adjustment device fixedly connected to the outer perimeter of the tower crane frame, and a protective device fixedly connected to the upper four corners of the adjustment device.

[0006] The adjustment device includes a left adjustment plate and a right adjustment plate. The front and right ends of the left and right adjustment plates are respectively provided with an adjustment groove and a sliding groove. A rear sliding plate is slidably connected between the two sliding grooves. The front left end of the left adjustment plate and the front right end of the right adjustment plate are both provided with screw holes. A No. 2 fixing bolt is threaded into the two screw holes. A connecting component is slidably connected to the front ends of the two adjustment grooves. A front sliding plate is slidably connected between the front left and front right ends of the two connecting components. The front end of the front sliding plate is provided with several screw holes. A No. 1 fixing bolt is threaded into the front ends of the two connecting components. The left and right adjustment plates are located on the left and right sides of the tower crane, respectively.

[0007] Preferably, the connecting assembly includes a front plate, a movable plate is fixedly connected to the left rear end of the front plate, a plurality of screw holes are opened at the left end of the movable plate, an adjustment groove is opened at the front right end of the front plate, a screw hole is opened at the right front end of the front plate, and the front plate is located on the left front side of the tower crane.

[0008] By adopting the above technical solution: screw hole three is used to cooperate with the second fixing bolt to realize the position adjustment and fixation of the left and right adjustment plates; adjustment groove two can be used to connect other components and adjust their relative positions; screw hole four cooperates with the first fixing bolt to realize the connection and position adjustment of the front sliding plate. The whole assembly enables the connection components to flexibly adapt to different installation requirements.

[0009] Preferably, the protective device includes four buckle blocks. Each of the four buckle blocks has a buckle groove in the middle of its outer side. An elastic outer rope frame is engaged in the four buckle grooves. Several elastic ropes are fixedly connected to the inner frame wall of the elastic outer rope frame. The buckle blocks are respectively fixedly connected to the upper end of the left adjustment plate, the upper end of the right adjustment plate, and the upper ends of the two front plates.

[0010] By adopting the above technical solution: four buckle blocks and their buckle slots, the elastic outer rope frame can be quickly installed and disassembled, and maintenance and replacement can be convenient. The elastic outer rope frame and the elastic rope strips combine to form a flexible protective structure, which can buffer and block climbers and enhance the protective effect.

[0011] Preferably, the positional dimensions of the two first fixing bolts on the front side are adapted to the positional dimensions of several screw holes one, and the positional dimensions of the two second fixing bolts are adapted to the positional dimensions of several screw holes three.

[0012] By adopting the above technical solution, it is ensured that the No. 1 fixing bolt and screw hole 1, and the No. 2 fixing bolt and screw hole 3 can be precisely matched. When adjusting the size of the device, the position of each component can be accurately fixed, ensuring the structural stability after adjustment.

[0013] Preferably, the two connecting components have the same structure and are symmetrically distributed from left to right, and both the left and right adjusting plates have an L-shaped structure.

[0014] By adopting the above technical solution: the symmetrical distribution of the connecting components makes the force on both sides of the adjustment device balanced during size adjustment, and the operation is more stable. The L-shaped left and right adjustment plate structure fits the side shape of the tower crane, making it easy to install and fix.

[0015] Preferably, the movable plates are slidably connected to the adjustment groove.

[0016] By adopting the above technical solution, the overall size of the adjustment device can be changed to achieve adaptive adjustment to different installation environments or changes in tower crane height.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, the adjustment device of this apparatus is L-shaped with left and right adjustment plates located on both sides of the tower crane frame. The first adjustment groove and the sliding groove provide a track for the movement of the components. The rear sliding plate slides in the sliding groove to adjust the width of the rear side of the device. The moving plate of the connecting component slides in the first adjustment groove. The front plate is connected to the front sliding plate through the first fixing bolt. By loosening or tightening the first fixing bolt and the second fixing bolt, the position of the front sliding plate and the connecting component can be easily changed, thereby flexibly adjusting the overall size of the device. In different construction sites, facing various models of tower cranes, or raising or lowering the height during tower crane construction, this device can quickly adapt, greatly improving the installation adaptability and construction efficiency, and overcoming the defects of traditional devices with fixed size and difficulty in adjustment.

[0019] 2. In this utility model, the protective device consists of buckle blocks, an elastic outer rope frame, and elastic ropes. The four buckle blocks are respectively fixed to the upper ends of the left adjustment plate, the right adjustment plate, and the two front plates. The elastic outer rope frame is engaged through buckle slots, and the elastic ropes are distributed on the inner wall of the elastic outer rope frame. When someone attempts to climb the tower crane, the elastic outer rope frame and elastic ropes can buffer and block the climber. Unlike traditional guardrails with excessive spacing that are easily breached, the elastic structure of this device can effectively disperse the impact force of the climber and prevent them from continuing to climb. This fundamentally reduces the risk of unauthorized personnel climbing into the tower crane, effectively ensuring the safety of the construction site and making up for the shortcomings of traditional devices in terms of poor protective effect.

[0031] In this embodiment, the adjusting device 3 includes a left adjusting plate 31 and a right adjusting plate 32. The front and right ends of the left adjusting plate 31 and the right adjusting plate 32 are respectively provided with adjusting grooves 310 and sliding grooves 33. A rear sliding plate 34 is slidably connected between the two sliding grooves 33. The front left end of the left adjusting plate 31 and the front right end of the right adjusting plate 32 are both provided with screw holes 311. A second fixing bolt 39 is threaded into each of the two screw holes 311. Connecting components 35 are slidably connected to the front ends of both adjusting grooves 310. A front sliding plate 36 is slidably connected between the front left and front right ends of the two connecting components 35. The front end of the front sliding plate 36 is provided with several screw holes 37. A first fixing bolt 38 is threaded into the front ends of the two connecting components 35. The left adjusting plate 31 and the right adjusting plate... 32 are located on the left and right sides of the tower crane 1, respectively. The connecting component 35 includes a front plate 351.

[0032] With the above scheme: the left adjusting plate 31 and the right adjusting plate 32 are L-shaped and located on the left and right sides of the tower crane 1, respectively. The adjusting grooves 310 at the front and right ends of the left adjusting plate 31 and the sliding grooves 33 at the front and right ends of the right adjusting plate 32 provide tracks for component movement. The rear sliding plate 34 slides within the two sliding grooves 33 to adjust the width of the rear side of the device. The moving plate 353 of the connecting assembly 35 slides within the adjusting groove 310. Its front plate 351 is connected to the front sliding plate 36 via a first fixing bolt 38. The screw hole 37 at the front end of the front sliding plate 36 is adapted to the first fixing bolt 38. Loosening the first fixing bolt 38 allows the front sliding plate 36 to slide between the connecting assemblies 35 to adjust the front dimension. At the same time, the left adjusting plate 34... The screw holes 311 on the front left end of plate 31 and the front right end of right adjusting plate 32 are threadedly connected to the second fixing bolt 39.
