Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to an anti-slip structure for a crane walkway. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. The main feature of a tire crane is that its driving cab and lifting control cab are combined into one. It evolved from a crawler crane, replacing the crawler tracks and traveling support of the traveling mechanism with a chassis with tires. This overcomes the disadvantage of crawler crane tracks damaging the road surface. It belongs to material handling machinery. To facilitate the movement and operation of workers, a walkway is installed on the main body of the crane frame.

[0003] Chinese utility model patent CN218931501U discloses a crane aluminum alloy walkway structure. This structure includes a main board, a liner at the lower end of the main board, a ladder connected to the middle of the liner, and a handle on the upper side of the main board. While this utility model allows for quick separation of the liner from the main board, water accumulation and the lack of slip resistance on the walkway during actual use can lead to accidents. Therefore, this utility model proposes an anti-slip structure for crane walkways to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-slip structure for a crane walkway to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip structure for a crane walkway, comprising: a mounting plate, a mounting groove on the upper surface of the mounting plate, a sliding plate detachably connected to the mounting groove via adjusting bolts, a return spring sleeved on the outer surface of the adjusting bolts, a positioning hole on the upper surface of the sliding plate, and a corresponding anti-slip post below the positioning hole. The components work together to form the foundation of the anti-slip structure, which can enhance the anti-slip effect through force linkage, providing stable support for subsequent functional optimization.

[0006] Preferably, the return spring is located between the mounting plate and the sliding plate, and the number of return springs corresponds to the number of adjusting bolts. The spring position ensures that the elastic action is direct and effective, and the corresponding number ensures balanced force distribution, thereby improving the stability of the sliding plate's reset and support.

[0007] Preferably, the outer surface of the sliding plate is slidably connected to the mounting groove, with the sliding plate located inside the mounting groove. The spring positions ensure direct and effective elastic action, and the corresponding number ensures balanced force distribution, improving the stability of the sliding plate's reset and support.

[0008] Preferably, the lower surface of the anti-slip post is fixedly connected to the mounting groove, and the positions of the anti-slip post and the adjusting bolts are arranged parallel to each other. The fixed connection ensures the stability of the anti-slip post position, and the parallel layout ensures uniform force distribution, enhancing the synergistic effect of anti-slip and fixation.

[0009] Preferably, a water guide channel is provided between each of the two adjacent sliding plates on the left and right sides, and installation positioning grooves are provided at the four corners of the outer surface of the mounting plate. The water guide channel drains water in time to prevent water accumulation from causing people to slip, and the positioning grooves facilitate installation and positioning, improving the practicality of the structure and the ease of installation.

[0010] Preferably, an installation guide groove is provided between each of the two adjacent installation positioning grooves on the left and right sides, and the interior of the installation guide groove is connected to the interior of the installation positioning groove. The guide groove assists in the rapid installation of the positioning groove, and the connected design reduces obstruction, improving installation efficiency and alignment accuracy.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model features an installation groove on the upper surface of the mounting plate, providing installation space and a sliding track for the sliding plate and anti-slip posts. The mounting groove is detachably connected to the sliding plate via adjusting bolts, which fix its position and allow sliding under force to cooperate with anti-slip. A return spring is sleeved on the outer surface of the adjusting bolt. When there is no force, the sliding plate is lifted to separate the anti-slip posts from the positioning holes. When force is applied, it is compressed to move them downwards. The upper surface of the sliding plate has positioning holes, and the lower surface has corresponding anti-slip posts. The greater the weight, the deeper the sliding plate is compressed. The compression spring moves downwards to make the anti-slip posts embed deeper into the positioning holes, increasing resistance to achieve better anti-slip, while not obstructing the drainage of accumulated water through the gap between the plates, thus avoiding accumulation.

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] The present application will be further described in detail below with reference to all the accompanying drawings.

[0016] Example 1: Reference Figures 1 to 4Mounting plate 1 has a mounting groove 4 on its upper surface. This mounting groove 4 provides mounting space and a sliding track for the sliding plate 5, and also provides a fixed base for the anti-slip post 7. The mounting groove 4 is detachably connected to the sliding plate 5 via adjusting bolts 8. The adjusting bolts 8 allow for adjustment and fixation of the sliding plate 5 within the mounting groove 4, facilitating subsequent disassembly and maintenance of the sliding plate 5. Adjusting the adjusting bolts 8 also controls the preload of the return spring. A return spring 9 is sleeved on the outer surface of the adjusting bolts 8, providing elastic support when the adjusting bolts 8 adjust the position of the sliding plate 5. To ensure the sliding plate 5 can stably fit against the mounting groove 4 and return to its original position, a positioning hole 10 is provided on the upper surface of the sliding plate 5, and a corresponding anti-slip post 7 is provided below the positioning hole 10. The positioning hole 10 can cooperate with the anti-slip post 7. When the sliding plate 5 is subjected to force, the anti-slip post 7 can be embedded in the positioning hole 10, enhancing the anti-slip effect of the surface of the sliding plate 5. The return spring 9 is located between the mounting plate 1 and the sliding plate 5. This position allows the return spring 9 to directly exert an elastic force on the mounting plate 1 and the sliding plate 5, preventing the sliding plate 5 from shaking in the mounting groove 4. The number of return springs 9 and the adjusting bolt 8 are specified. The corresponding quantity ensures that each adjusting bolt 8 has a return spring 9 providing elastic support, ensuring uniform force on the sliding plate 5 and stable adjustment. The outer surface of the sliding plate 5 is slidably connected to the mounting groove 4. Through this connection, the sliding plate 5 can flexibly adjust its position in the mounting groove 4 according to different requirements for anti-slip strength in actual use, position calibration after component wear, etc., ensuring that it always maintains a reasonable cooperation with the anti-slip post 7, return spring 9, and other components, thereby maintaining the stable operation of the overall structure and the effective performance of the anti-slip function. Located inside the mounting groove 4, the internal design prevents the sliding plate 5 from protruding from the surface of the mounting plate 1. At the same time, the mounting groove 4 encloses and limits the sliding plate 5, preventing it from shifting. The lower surface of the anti-slip post 7 is fixedly connected to the mounting groove 4. This fixed connection ensures that the anti-slip post 7 is in a stable position and can continuously play an anti-slip role when it is engaged with the positioning hole 10 without displacement. The anti-slip post 7 and the adjusting bolt 8 are set parallel to each other. This parallel setting allows the anti-slip post 7 and the adjusting bolt 8 to be evenly distributed within the mounting groove 4, jointly ensuring the stability of the sliding plate 5 from both anti-slip and fixing angles.

[0017] Reference Figures 1 to 3Water guide grooves 6 are provided between the two adjacent sliding plates 5 on the left and right sides. The water guide grooves 6 can guide and drain the water accumulated on the surface of the sliding plate 5, so as to avoid the water from affecting the sliding performance of the sliding plate 5 and the anti-slip effect of the anti-slip column 7, and to prevent people from stepping on the water and getting injured. The four corners of the outer surface of the mounting plate 1 are provided with mounting positioning grooves 3. The mounting positioning grooves 3 are used for positioning and installing the crane platform plate and other components, ensuring that the mounting plate 1 is accurately installed on the platform plate. The two adjacent mounting positioning grooves 3 on the left and right sides are provided with mounting guide grooves 2, and the interior of the mounting guide grooves 2 is connected to the interior of the mounting positioning grooves 3. The mounting guide grooves 2 can assist the mounting positioning grooves 3 in installation, making it convenient for the installation components to quickly enter the mounting positioning grooves 3. At the same time, the connected design can reduce obstacles during installation and improve installation efficiency.

[0018] Working principle: First, the mounting plate 1 is positioned and installed on the crane platform by engaging the mounting positioning grooves 3 at the four corners with the mounting guide grooves 2. The mounting guide grooves 2 assist the installation components to quickly enter the position, improving installation efficiency. Within the mounting groove 4 of the mounting plate 1, the sliding plate 5 is connected by adjusting bolts 8, allowing the outer surface of the sliding plate 5 to slide against the mounting groove 4 and remain within it. Simultaneously, a return spring 9 is fitted onto the outer surface of the adjusting bolts 8, ensuring that the return springs 9 are positioned between the mounting plate 1 and the sliding plate 5, and that their number corresponds to the adjusting bolts 8. The position of the sliding plate 5 within the mounting groove 4 is adjusted by the adjusting bolts 8, with the return springs 9 providing elastic support. The sliding plate 5 is stably fitted into the mounting groove 4. At this time, the anti-slip post 7 (the lower surface is fixed to the mounting groove 4 and the position is parallel to the adjusting bolt 8) corresponds to the positioning hole 10 on the sliding plate 5 but is not embedded. When a person stands on the sliding plate 5, the sliding plate 5 is compressed and the return spring 9 moves down along the mounting groove 4, so that the anti-slip post 7 is embedded in the positioning hole 10 to enhance the anti-slip effect. The greater the weight, the deeper the embedding and the stronger the anti-slip effect. The water generated during use is discharged through the water guide groove 6 between the left and right adjacent sliding plates 5 to avoid affecting the sliding performance and anti-slip effect. If it is necessary to maintain or replace the sliding plate 5, it can be removed from the mounting groove 4 by loosening the adjusting bolt 8. The operation is convenient.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
