DETAILED DESCRIPTION

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 This utility model provides a technical solution: a cable hook limiting device, including a cable equipment frame 1, a cable wheel 2, a connecting frame 3, a positioning frame 4, an auxiliary frame 5, a connecting frame 6, a guide frame 7, a limiting frame 8, a telescopic frame 9, a rolling bottom rod 10, a cable limiting wheel 11, a first traction ring 12, a spring rod 13, a second traction ring 14, and a laser rangefinder 15;

[0033] Among them, the cable equipment frame 1 is the output end frame of the cable equipment. The cable equipment frame 1 is rotatably connected to the cable wheel 2. The upper end of the cable equipment frame 1 has an opening, and the connecting frame 3 is inserted into the opening of the cable equipment frame 1. The connecting frame 3 and the cable equipment frame 1 are connected to form the frame connection structure of the cable hook limiting device.

[0034] The upper end of the connecting frame 3 is connected to the positioning frame 4 by bolts, and an auxiliary frame 5 is provided below the positioning frame 4. One end of the auxiliary frame 5 is connected to the side wall of the connecting frame 3, and the other end of the auxiliary frame 5 has a connecting frame 6. The connecting frame 6 is an L-shaped metal frame, and the connecting frame 6 is installed at one end of the positioning frame 4. The bottom end of the connecting frame 3 is a ring structure, and the ring structure of the connecting frame 3 is penetrated by the axle of the cable wheel 2. The connecting frame 3 and the positioning frame 4 are L-shaped.

[0035] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the connecting frame 3 installed at the cable equipment frame 1 is inserted into the cable equipment frame 1 through a ring structure at its bottom end, and then the cable equipment frame 1 and the connecting frame 3 are connected by the axle of the cable wheel 2, as shown. Figure 1 As shown, the positioning frame 4 installed on the upper end of the connecting frame 3 increases the connection point with the connecting frame 6 through the auxiliary frame 5. The connecting frame 6 adds a limiting environment for the connection between the positioning frame 4 and the guide frame 7. When in use, the cable of the cable wheel 2 moves from the bottom of the positioning frame 4 to one side, passes through the two connecting frames 6 and enters the guide frame 7. The connecting frame 3, positioning frame 4, auxiliary frame 5 and connecting frame 6 form a structure that wraps around the working port of the cable and hook of the cable equipment frame 1 and the cable wheel 2, further limiting the range of motion of the cable hook and providing a safe working range for the cable wheel 2.

[0036] The end of the positioning frame 4 connected to the adapter frame 6 is provided with a guide frame 7, and the guide frame 7 is provided in an L-shaped structure. A telescopic frame 9 is arranged at the port of the bottom end of the guide frame 7, and the output end of the telescopic frame 9 is rotatably connected to one end of a rolling bottom rod 10. The rolling bottom rod 10 is rotatably connected to the surface of a limiting frame 8, and the limiting frame 8 is mounted on the surface of the adapter frame 6. The rolling bottom rod 10 is arranged in parallel with the cable limiting wheel 11 in an up-down manner. The two ends of the rolling bottom rod 10 are respectively connected to one telescopic frame 9. The telescopic frame 9 is a two-section slidingly connected sleeve rod structure. The positioning frame 4 is provided in an H-shaped frame body. A metal rod is mounted at the connection between the positioning frame 4 and the adapter frame 6. A traction ring two 14 is arranged at the horizontal rod of the H-shaped frame body of the positioning frame 4. The metal rod of the positioning frame 4 penetrates the traction ring one 12. The surface of the traction ring one 12 is connected to the guide frame 7. The traction ring one 12 is arranged in parallel with the traction ring two 14. One laser range finder 15 is arranged on each side of the traction ring one 12. One end of the traction ring two 14 is provided with a spring rod 13. The other end of the spring rod 13 is connected to the traction ring one 12. The spring rod 13 is composed of a sliding sleeve and a spring. The laser range finder 15 is mounted on the surface of the positioning frame 4. The heights of the two laser range finders 15 are consistent.

[0037] In combination with the Figures 1-6 As shown in the drawings, the traction ring one 12, the spring rod 13 and the traction ring two 14 arranged at the connection between the horizontal rod of the positioning frame 4 and the metal frame increase the traction structure with the guide frame 7, as Figures 1-2 As shown in the drawings, the two-section slidingly connected sleeve and spring of the spring rod 13 are matched to increase the auxiliary buffering means when the traction ring one 12 receives external impact. The adapter frame 6 mounted on both sides of the guide frame 7 and the traction ring one 12 limits the overall position. The laser range finder 15 mounted on the inner side of the positioning frame 4 detects the position of the traction ring one 12. When the overall traction ring one 12 tilts, the distance between the two sides of the traction ring one 12 changes, so that the detection data of the laser range finder 15 is abnormal. The laser range finder 15 is directly connected to the cable hook control system through a cable during use to send an alarm and control the cable to stop working. The cable limiting wheel 11 mounted in the guide frame 7 guides the output direction of the cable with the rolling bottom rod 10. The rolling bottom rod 10 is pushed and adjusted in height by the output end of the telescopic frame 9 to facilitate the guidance of cables of different thicknesses. The limiting frame 8 mounted on one side of the adapter frame 6 avoids the impact on the cable wheel 2 during the recovery of the hook, as Figure 1 As shown in the drawings, the limiting frame 8 guides the cable while avoiding direct impact on the cable wheel 2 during the recovery of the hook, forming a certain protection range. Since the movement of the hook is strictly limited within a safe range, the risk of heavy object falling is greatly reduced, thereby effectively protecting the life safety of personnel at the construction site. The overall structure of the device is simple and convenient for rapid assembly, can adapt to different operation scenes, and is conveniently installed on cable cranes of different types and specifications, has good compatibility, and does not need to make large-scale modifications to the crane structure, thereby reducing the equipment upgrading cost.

[0038] Working principle: when using the cable hook limiting device, the cable passes through the cable wheel 2 in the cable equipment rack 1 in the construction direction of the cable, the cable passes through the rolling bottom rod 10 and the cable limiting wheel 11, the height of the rolling bottom rod 10 is adjusted with the length of the telescopic frame 9, the limiting frame 8 at both ends of the rolling bottom rod 10 limits the position of the hook recovery, avoids the excessive impact of the hook on the cable equipment rack 1 or the cable wheel 2 when the cable is recovered, the spring rod 13 between the traction ring one 12 and the traction ring two 14 buffers the external impact when the limiting frame 8 receives the impact transmission, the laser range finder 15 detects the installation position of the traction ring one 12, stops the work of the cable when the traction ring one 12 is detected to be offset, the guide frame 7 installed on the surface of the traction ring one 12 is in an offset state, which is easy to offset the cable hook to one side, affects the construction use, the cable equipment rack 1 and the positioning frame 4 are connected and installed higher than the moving height of the cable from the cable wheel 2, which is convenient for increasing the limiting device of the cable and the connected hook, and increases the practicability of the whole.
