Description

Technical Field

[0001] The present application relates to the technical field of cableway hooks, and in particular to a hook for an overhead freight cableway. Background Art

[0002] Overhead freight ropeway is a transportation system that uses steel wire ropes erected in the air to transport goods. It is mainly composed of transmission devices, load-bearing ropes, traction ropes, transport containers, line brackets, hooks, etc. When using ropeway to transport goods, in addition to using transport containers, hooks will also be used to cooperate with hooks. This method saves the procedure of handling goods. The goods are packed and transported by using hooks and hooks. The hooks of this method are mostly common hooks or rings. For goods with low requirements, ropes are directly knotted as hooks.

[0003] The Chinese patent with announcement number CN206694388U and name "A hook for a single-wheel and single-cable freight trolley on a standardized freight ropeway" specifically includes a self-locking device, a unhooking web and a hook. A limit pin is arranged on the unhooking web above the self-locking device. This small improvement prevents the self-locking device from falling off and greatly improves the safety performance of the trolley operation.

[0004] The above-mentioned existing technology can prevent the self-locking device from falling off when in use. However, the above-mentioned existing technology is mainly aimed at the design of transport containers during cableway lifting. When transporting goods, it is necessary to transport the goods to the trolley back and forth to complete the lifting operation. The hook connection and unhooking process of the lifting operation require staff to handle. In addition, the self-locking device disclosed in the above-mentioned technology does not limit the hook connected to the trolley during work. Although it can prevent the trolley from falling off the hook, the problem of bumps or swings during the lifting process is still not involved. Based on this, there is still room for improvement on the basis of the existing freight cableway hooks. Summary of the invention

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1, please refer to Figure 1-7 A hook for an overhead freight ropeway provided in an embodiment of the present invention comprises a fixed sleeve 1, the fixed sleeve 1 is an arc structure with an opening at the lower end, which is convenient for placing a hook or a lifting ring into the fixed sleeve 1, a locking column 2 is slidably arranged in the fixed sleeve 1, the locking column 2 is used to block the opening of the fixed sleeve 1, a spring rope 21 is arranged between the locking column 2 and the inner wall of the fixed sleeve 1, and the locking column 2 has a locking position and an initial position within the sliding trajectory of the fixed sleeve 1; an adjusting component 3 is arranged on the fixed sleeve 1 and connected to the locking column 2, and is used to control the movement of the locking column 2 during operation; a locking component 4 is arranged in the locking column 2, and the locking column 2 is fixed in the fixed sleeve 1 by the locking component 4 during the lifting operation.

[0032] By adopting the above technical scheme, in the process of lifting goods by cableway, the hook designed by the present invention can be adjusted to adapt to a variety of different hooks. In common cargo lifting, the hook is usually connected with a rope, a hanging ring or a hook. During operation, the locking column 2 can slide in the fixed sleeve 1, and has the function of a hook and a ring hook. It does not need to be replaced during the process of lifting goods. According to specific circumstances, a cylinder for controlling the up and down movement of the present invention can be added between the fixed sleeve 1 and the equipment sliding on the cableway. The cylinder controls the adjustment component 3 to drive the locking column 2 to move toward the locking position. When the hook and the hook are in a taut state, the locking component 4 works to make the locking column 2 stably connected to the fixed sleeve 1. The hook in the present invention can automatically cooperate with the hook on the cargo, and can automatically complete the connection with the cargo during the lifting operation; the locking component 4 is affected by the gravity of the hook during operation. When there is no contact between the hook and the locking column 2, the locking component 4 automatically resets, and the adjustment component 3 controls the locking column 2 to separate from the fixed sleeve 1 in this state, thereby controlling the connection and separation operation of the hook and the hook on the cargo.

[0033] Reference Figure 1 , Figure 2 as well as Figure 5 As shown, the adjustment component 3 includes an adjustment ring 31 slidably set on the fixed sleeve 1, the adjustment ring 31 is connected to the locking column 2 through an adjustment block 32, the adjustment block 32 is slidably set in the sliding groove 101, and a wire ring 33 is symmetrically set at the opening position of the fixed sleeve 1. A pull rope 34 is connected to the adjustment ring 31, and the pull rope 34 passes through the wire ring 33 located on the right side of the fixed sleeve 1 and is connected to the wire ring 33 located on the left side of the fixed sleeve 1.

[0034] By adopting the above technical solution, during operation, when the hook for lifting goods is a circular ring or a hook-shaped structure, the hook designed in the present invention is controlled to move downward, and during the movement, the hook squeezes the pull rope 34, and the squeezed pull rope 34 synchronously controls the adjustment ring 31 to slide on the fixed sleeve 1, and the adjustment ring 31 synchronously pulls the locking column 2 toward the locking position through the adjustment block 32 during the movement, and when the locking column 2 moves to the locking position, the locking member 5 works to temporarily lock the locking column 2 on the fixed sleeve 1.

[0035] Reference Figure 2 As shown, the fixed sleeve 1 includes a sliding groove 101 opened on the fixed sleeve 1, and the sliding groove 101 is communicated with the inner wall of the fixed sleeve 1. The locking column 2 is a semicircular structure, and a locking piece 5 is provided on the locking column 2.

[0036] Reference Figure 3-7As shown, the locking member 5 includes a locking groove 201 provided on the locking column 2, a movable slide groove 202 connected to the locking groove 201 is provided on the locking column 2, a linkage rod 51 is slidably provided in the locking groove 201, an elastic member 52 is provided between the linkage rod 51 and the locking groove 201, a locking ring 53 is slidably provided in the movable slide groove 202, a return spring 55 is provided between the locking ring 53 and the movable slide groove 202, a locking rod 54 is slidably provided in the locking ring 53, a guide groove 203 is provided on the linkage rod 51, the locking rod 54 is slidably provided in the guide groove 203, the cross-section of the guide groove 203 is a T-shaped groove, a cylindrical protrusion 56 is provided on the inner wall of the left side of the fixed sleeve 1, and a locking hole matching the locking rod 54 is provided on the fixed sleeve 1.

[0037] The guide groove 203 includes a lifting portion and two reset portions. The reset portions are located on both sides of the lifting portion, and the lifting portion and the reset portions are connected via inclined portions.

[0038] By adopting the above technical solution, during operation, when the locking column 2 moves toward the locking position, the cylindrical protrusion 56 first squeezes the linkage rod 51, and the linkage rod 51 after being squeezed moves toward the inner direction of the locking groove 201. At this time, the locking rod 54 contacts the reset part, and when the linkage rod 51 moves, the position where the locking rod 54 contacts the guide groove 203 gradually moves toward the lifting part. When the locking column 2 moves to the locking position, the locking rod 54 is located at the lifting part of the guide groove 203, and the locking rod 54 passes through the locking ring 53 and is inserted into the locking hole in this state, so that the locking column 2 is temporarily locked on the fixed sleeve 1, and the preparation work for cargo lifting is completed in this state.

[0039] When the cargo is hoisted to the destination and needs to be removed from the hook, the cargo on the hook is first controlled by the cylinder to contact the ground or other loads, so that the hook on the cargo is separated from the locking column 2. After the hook is separated from the locking column 2, the pressure on the locking component 4 is released synchronously, and the locking component 4 is reset. At this time, the hook is still in a state of squeezing the pull rope 34;

[0040] The cylinder drives the hook to move upward. After the hook is separated from the pull rope 34, the locking column 2 moves toward the initial position under the action of the spring rope 21. In this state, the locking rod 54 is still located in the locking hole. At this time, when the locking column 2 moves, the locking rod 54 is in a stationary state, and the locking ring 53 moves synchronously in the moving slide groove 202. At this time, the linkage rod 51 follows the movement of the locking column 2 and separates from the cylindrical protrusion 56. The linkage rod 51 is reset by the elastic member 52 in this process. During the resetting process, the linkage rod 51 synchronously changes the contact position between the locking rod 54 and the guide groove 203, so that the contact position between the guide groove 203 and the locking rod 54 moves from the jacking part to the reset part. At this time, the locking column 2 moves to the initial position under the action of the spring rope 21.

[0041] Reference Figure 3-5 As shown, the locking assembly 4 includes a fixed block 41 arranged on the locking column 2, a mounting groove 401 is opened on the fixed block 41, a limiting frame 42 is symmetrically installed in the mounting groove 401 through a torsion spring, a control groove 402 connected to the mounting groove 401 is opened in the middle of the locking column 2, and a wire hole 403 connected to the control groove 402 is symmetrically opened in the locking column 2, a locking piece 43 is arranged at the wire hole 403 away from one end of the control groove 402, a control piece 44 is arranged in the control groove 402, and the control piece 44 is connected to the locking piece 43 by a steel wire rope 45, and the steel wire rope 45 passes through the wire hole 403.

[0042] By adopting the above technical scheme, when the hook and the hook are in a taut state during operation, the hook squeezes the limit frame 42 under the action of the gravity of the cargo and simultaneously squeezes the control member 44, and the limit frame 42 can limit the upper side of the hook under the action of the torsion spring. After the control member 44 is squeezed, it controls the locking member 43 to work by pulling the wire rope 45. The locking member 43 fixes the locking column 2 on the fixed sleeve 1 during operation. The two limit frames 42 are reset under the action of the torsion spring, and the hook is in the installation groove 401 to limit the hook. In order to improve the stability of cargo lifting, the current hook or lifting ring can be designed with a hole. The hook or lifting ring with a hole during operation can cooperate with the control member for further limiting, which can reduce the swing amplitude of the cargo during transportation.

[0043] The control member 44 includes a control rod 441 slidably arranged in the control groove 402, a control spring 442 is arranged between the control rod 441 and the control groove 402, and steel wire ropes 45 are symmetrically connected to both ends of the control rod 441. The steel wire ropes 45 pass through the wire hole 403 and are connected to the control rod 441. The upper end of the control rod 441 is a cylindrical protrusion structure, and the depth of the opening on the hook or the ring corresponds to the protrusion on the control rod 441.

[0044] The locking member 43 includes a locking groove 404 opened on the locking column 2 and connected with the wire hole 403. The locking column 2 is evenly provided with plug-in holes 405 along its circumference. The plug-in holes 405 are connected to the locking groove 404. A plug-in rod 431 is slidably arranged in the plug-in hole 405. An elastic rubber block is arranged between the plug-in rod 431 and the locking groove 404. An extrusion column 433 is installed in the locking groove 404 through a spring rod 432. The extrusion column 433 is a stepped structure. The extrusion column 433 is connected to the wire rope 45. One end of the plug-in rod 431 located in the locking groove 404 is fitted on the extrusion column 433. A locking hole matching the plug-in hole 405 is opened on the fixed sleeve 1.

[0045] By adopting the above technical solution, the control rod 441 is synchronously squeezed during the downward movement of the hook in a specific operation. The control rod 441 moves from top to bottom after being squeezed. The control rod 441 synchronously pulls the wire rope 45 to move during the movement. The wire rope 45 drives the control squeezing column 433 to move during the movement. The squeezing column 433 squeezes the plug-in rod 431 during the movement. The plug-in rod 431 passes through the plug-in hole 405 and is inserted into the locking hole in this process, so that the locking column 2 is fixed on the fixed sleeve 1. Through the cooperation among the above-mentioned middle control member 44, the locking member, the limit frame 42, the cylindrical protrusion on the control rod and the open hole hook, the swing amplitude of the goods during transportation can be limited, thereby improving the safety and stability of the goods lifting.

[0046] Example 2, the same as Example 1 is not described here, the difference from Example 1 is: please refer to Figure 2-8 As shown, the adjustment assembly 3 includes a moving block 7 slidably disposed in a sliding groove 101 , the moving block 7 is connected to the locking column 2 , an electric slider 6 is disposed on the fixed sleeve 1 , and the locking column 2 is connected to the electric slider 6 .

[0047] By adopting the above technical solution, during operation, the electric slider 6 is used to control the moving block 7 to slide in the moving groove. The moving block 7 synchronously controls the locking column 2 to move in the fixed sleeve 1. When preparing to lift the goods, the electric slider 6 controls the locking column 2 to move from the initial position toward the locking position. When the cargo lifting operation is completed, the electric slider 6 controls the locking column 2 to move from the locking position toward the initial position. This embodiment not only uses a hook in a ring shape or a hook shape, but also makes it more convenient to transport goods with a hook in the form of a rope.

[0048] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
