Technical Field

[0001] The utility model relates to the field of steel gangplanks, in particular to a steel gangplank locking device. Background Technique

[0002] A scaffolding is a working framework erected to ensure the smooth progress of each construction process during civil engineering construction. After the scaffolding is erected, it is also necessary to lay gangplanks to provide a working platform for construction workers. Generally, steel gangplanks are selected during construction. After the steel gangplanks are laid on the scaffolding, a locking device is required to lock the steel gangplanks to prevent them from moving.

[0003] For the existing steel gangplank locking device, there are hooks and locking hooks. The steel strip board can be stably installed on the scaffolding through the cooperation of the hooks and the locking hooks, and anti-slip pads are provided on the inner walls of the hooks and the locking hooks to improve the locking stability of the locking device. However, the anti-slip pads may be worn after long-term use. To ensure their anti-slip effect, they need to be replaced. However, since the anti-slip pads are fixed on the inner walls of the hooks and the locking hooks, it is difficult to disassemble the anti-slip pads, resulting in troublesome replacement, and thus reducing the disassembly, installation and replacement efficiency of the anti-slip pads. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a steel gangplank locking device to solve the technical problem of inconvenient disassembly and replacement of the anti-slip pad.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A steel gangplank locking device includes a steel gangplank. Hooks are fixedly connected to both sides of the steel gangplank. Locking hooks are connected to the lower sides of both sides of the steel gangplank through rotating shafts. An anti-slip component is arranged inside the locking hook, and the anti-slip component includes slots opened inside the hook and the locking hook and threaded columns threaded on the hook and the locking hook. One end of the threaded column is connected with a push block through a bearing. An insertion block is inserted into the slot. Grooves are opened on both sides inside the insertion block. An anti-slip pad is installed on the insertion block. Two movable blocks are also slidably connected inside the slot. A clamping block extending into the groove is installed on one side of the movable block.

[0006] By adopting the above technical scheme, when it is necessary to install the anti-slip pad, the insertion block at the bottom of the anti-slip pad can be inserted into the slot. At this time, the clamping block is aligned with the groove, and then the staff can rotate the threaded column to make the threaded column move.

[0007] Furthermore, a chute is opened on the inner wall of the slot, and a spring is fixed inside the chute. One end of the spring is connected with a sliding block, and the sliding block is connected with the movable block.

[0008] By adopting the above technical solution, when the movable block moves, it will drive the slider to slide inside the chute, so as to guide the movable block, thereby improving the stability of the movable block when it moves.

[0009] Furthermore, the slider is slidably connected to the chute, and the spring is made of stainless steel material.

[0010] By adopting the above technical solution, the slider can slide inside the chute, and the slider will squeeze the spring, causing the spring to be compressed by the force, which is convenient for pushing the slider to move back to its original position subsequently.

[0011] Furthermore, a limiting rod penetrating outside the hook and the locking hook is installed on the pushing block.

[0012] By adopting the above technical solution, when the pushing block moves, it will drive the limiting rod to move, and the limiting rod can guide the pushing block to prevent the pushing block from rotating.

[0013] Furthermore, a first connecting plate is fixed on one side of the hook, and a locking bolt is provided on the first connecting plate.

[0014] By adopting the above technical solution, the locking bolt can be screwed into the inside of the first connecting plate and the second connecting plate, so as to lock and fix the first connecting plate and the second connecting plate.

[0015] Furthermore, a second connecting plate is fixed on one side of the locking hook, and a limiting nut is sleeved at the bottom end of the locking bolt.

[0016] By adopting the above technical solution, when the limiting nut is sleeved on the locking bolt and fits against the bottom of the second connecting plate, the hook and the locking hook can be fixed.

[0017] Furthermore, the locking hook is rotatably connected to the steel plank through a rotating shaft.

[0018] By adopting the above technical solution, it is convenient for the locking hook to rotate through the rotating shaft. When the locking hook rotates and opens, the hook can be sleeved on the scaffold.

[0019] Furthermore, the two anti-slip pads are respectively attached to the inner walls of the hook and the locking hook.

[0020] By adopting the above technical solution, the anti-slip pads can be attached to the outer wall of the scaffold, thereby improving the stability of the hook and the locking hook and preventing the hook and the locking hook from moving randomly.

[0021] Furthermore, one side of the movable block and both sides of the pushing block are provided with inclined surfaces, and both sides of the pushing block are in contact with the movable block.

[0022] By adopting the above technical solution, when the pushing block moves, it will push two movable blocks to move, and the movable blocks will drive the clamping block to move.

[0023] Furthermore, the clamping block is located inside the clamping groove, and the clamping block is adapted to the clamping groove.

[0024] By adopting the above technical solution, after the clamping block is inserted into the inside of the clamping groove, the inserting block can be limited and fixed to prevent the inserting block from moving inside the inserting slot.

[0025] In summary, the main beneficial effects of the present utility model are as follows:

[0026] In the present utility model, by providing an anti-slip component, when it is necessary to install an anti-slip pad, the inserting block at the bottom of the anti-slip pad can be inserted into the inside of the inserting slot. At this time, the clamping block is aligned with the clamping groove, and then the staff can rotate the threaded column, so that the threaded column moves and drives the pushing block to move, and the pushing block pushes the movable block to move, and the movable block drives the clamping block to move, so that the clamping block is inserted into the inside of the clamping groove to limit and fix the inserting block. At this time, the anti-slip pad can be attached to the inner wall of the hanging hook or the locking hook, thus completing the installation of the anti-slip pad. When disassembling the anti-slip pad for replacement, only need to rotate the threaded column in the reverse direction, so that the threaded column moves in the reverse direction and drives the pushing block to move back to its original position. At this time, the pushing block no longer presses the movable block, the spring stretches and then pushes the sliding block to move back to its original position, and drives the movable block to move back to its original position, and then drives the clamping block to move back to its original position, so that the clamping block moves out of the inside of the clamping groove and no longer limits and fixes the inserting block. At this time, the anti-slip pad can be taken out and replaced. And this replacement operation process is simple and convenient, without consuming too much time, thereby improving the disassembly, installation and replacement efficiency of the anti-slip pad.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0035] The following will describe the embodiments according to the overall structure of the present invention.

[0036] Embodiment 1:

[0037] A locking device for a steel gangplank, as Figures 1 - 6 shown, includes a steel gangplank 1. Hooks 2 are fixedly connected to both sides of the steel gangplank 1. Locking hooks 4 are connected to the lower sides of both sides of the steel gangplank 1 through rotating shafts 3. A first connecting plate 5 is fixed on one side of the hook 2. A locking bolt 6 is provided on the first connecting plate 5 so that the locking bolt 6 can be screwed into the interiors of the first connecting plate 5 and the second connecting plate 7, thereby achieving the purpose of locking and fixing the first connecting plate 5 and the second connecting plate 7. A second connecting plate 7 is fixed on one side of the locking hook 4. A limit nut 8 is sleeved at the bottom end of the locking bolt 6. When the limit nut 8 is sleeved on the locking bolt 6 and abuts against the bottom of the second connecting plate 7, the hook 2 and the locking hook 4 can be fixed. The locking hook 4 is rotatably connected to the steel gangplank 1 through the rotating shaft 3, facilitating the rotation of the locking hook 4 through the rotating shaft 3. When the locking hook 4 is rotated and opened, the hook 2 can be sleeved on the scaffolding.

[0038] Refer to Figures 1 - 5, an anti-slip component 9 is provided inside the locking hook 4, and the anti-slip component 9 includes a slot 902 opened inside the hook 2 and the locking hook 4 and a threaded post 908 threadedly connected to the hook 2 and the locking hook 4. The other end of the threaded post 908 is connected to a knob 910, which facilitates the staff to rotate the threaded post 908 through the knob 910. One end of the threaded post 908 is connected to a push block 907 through a bearing. An insertion block 903 is inserted into the slot 902, and clamping grooves 904 are opened on both sides inside the insertion block 903. And an anti-slip pad 901 is installed on the insertion block 903. The two anti-slip pads 901 are respectively attached to the inner walls of the hook 2 and the locking hook 4. The anti-slip pad 901 can be attached to the outer wall of the scaffolding, so as to improve the stability of the hook 2 and the locking hook 4 and prevent the hook 2 and the locking hook 4 from moving randomly. Two movable blocks 906 are also slidably connected inside the slot 902, and a clamping block 905 extending into the clamping groove 904 is installed on one side of the movable block 906.

[0039] Specifically, the clamping block 905 is located inside the clamping groove 904, and the clamping block 905 is adapted to the clamping groove 904. After the clamping block 905 is inserted into the clamping groove 904, the insertion block 903 can be limited and fixed to prevent the insertion block 903 from moving inside the slot 902. When the anti-slip pad 901 needs to be installed, the insertion block 903 at the bottom of the anti-slip pad 901 can be inserted into the slot 902. At this time, the clamping block 905 is aligned with the clamping groove 904. Then the staff can rotate the threaded post 908 to make the threaded post 908 move. One side of the movable block 906 and both sides of the push block 907 are provided with inclined surfaces. Both sides of the push block 907 are in contact with the movable block 906. When the push block 907 moves, it will push the two movable blocks 906 to move, and the movable block 906 will drive the clamping block 905 to move.

[0040] Specifically, a sliding groove 913 is further opened on the inner wall of the slot 902, and a spring 911 is fixed inside the sliding groove 913. One end of the spring 911 is connected to a slider 912, and the slider 912 is connected to the movable block 906. When the movable block 906 moves, it will drive the slider 912 to slide inside the sliding groove 913 to guide the movable block 906, thereby improving the stability of the movable block 906 when it moves. The slider 912 is slidably connected to the sliding groove 913. The spring 911 is made of stainless steel material. When the slider 912 moves, it will compress the spring 911, so that the spring 911 is compressed by force, which is convenient for the subsequent reset movement of the slider 912.

[0041] Embodiment Two:

[0042] On the basis of the above Embodiment One, in order to improve the stability of the push block 907 when it moves, the push block 907 needs to be guided. Therefore, the following structure is set up.

[0043] Refer to Figures 3 - 6, a limiting rod 909 passing through to the outside of the hook 2 and the locking hook 4 is installed on the pushing block 907. When the pushing block 907 moves, it will drive the limiting rod 909 to move. The limiting rod 909 can guide the pushing block 907 to prevent the pushing block 907 from rotating.

[0044] The working principle of the present utility model is as follows: First, during use, the staff can place the hook 2 on the surface of the scaffolding and make the inner wall of the anti-slip pad 901 fit with the outer wall of the scaffolding. Then, rotate the locking hook 4 and turn the locking hook 4 to the lower side of the hook 2, and make the anti-slip pad 901 inside the locking hook 4 fit with the scaffolding to prevent the locking hook 4 and the hook 2 from sliding randomly. At this time, the first connecting plate 5 and the second connecting plate 7 are in contact. Then, the staff rotates the locking bolt 6 and screws the locking bolt 6 into the first connecting plate 5 and the second connecting plate 7. Then, rotate the limit nut 8 so that the top of the limit nut 8 is in contact with the second connecting plate 7, so as to fix the hook 2 and the locking hook 4, and thus the steel plank 1 can be locked on the scaffolding;

[0045] When disassembling the anti-slip pad 901 for replacement, only need to rotate the threaded column 908, so that the threaded column 908 moves and drives the pushing block 907 to move back. At this time, the pushing block 907 no longer presses the movable block 906, and the spring 911 stretches and then pushes the slider 912 to reset, and drives the movable block 906 to move back, and then drives the clamping block 905 to move back, so that the clamping block 905 moves out of the clamping groove 904 and no longer limits and fixes the inserting block 903. At this time, the anti-slip pad 901 can be taken out and replaced;

[0046] When installing the anti-slip pad 901, the inserting block 903 at the bottom of the anti-slip pad 901 can be inserted into the slot 902. At this time, the clamping block 905 is aligned with the clamping groove 904. Then, the staff can reversely rotate the threaded column 908, so that the threaded column 908 moves and drives the pushing block 907 to move, and the pushing block 907 pushes the movable block 906 to move, and the movable block 906 drives the clamping block 905 to move, so that the clamping block 905 is clamped into the clamping groove 904 to limit and fix the inserting block 903. At this time, the anti-slip pad 901 can fit with the inner wall of the hook 2 or the locking hook 4, thus completing the installation of the anti-slip pad 901.
