Description

Technical Field

[0001] The utility model relates to the technical field of railway transportation, and more specifically to the technical field of a double hook structure capable of being opened and closed quickly. Background Art

[0002] At present, when transporting military wheeled equipment by rail, light, medium and heavy-duty pulling ropes with chain links as the main structure are usually used to tie and reinforce the wheeled equipment. The heavy-duty rope uses double hook assemblies, double hook hanging rings and other components to tie the axles at one end, and the double hook hanging ring is mounted and unmounted from the double hook assembly every time it is used. Since the operation of opening and closing the double hook assembly is relatively complicated, in actual use, the mounting and unmounting of the double hook hanging ring takes a lot of time, which is extremely inconvenient.

[0003] Therefore, the utility model improves the structure of the double hook assembly and adopts a torsion spring and a stop block structure, which can realize the rapid mounting and removal of the double hook hanging ring, improves the installation efficiency of the binding reinforcement equipment, and has the advantages of easy maintenance and low cost. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide a double hook structure that can be opened and closed quickly.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] The utility model provides a double hook structure which can be opened and closed quickly, comprising a double hook assembly, two double hook hanging rings which can be hung on the double hook assembly, two rebound locking mechanisms which prevent the two double hook hanging rings from falling, and a distance fine-tuning mechanism which is arranged on the double hook assembly and has an adjustable distance.

[0007] In one embodiment, the double hook assembly includes a T-shaped structure, both ends of the crossbar of the T-shaped structure are provided with limiting portions, and the ends of the vertical plates of the T-shaped structure are connected to the distance fine-tuning mechanism.

[0008] In one embodiment, two rebound locking mechanisms are symmetrically arranged at the upper end of the side wall of the distance fine-tuning mechanism, and each distance fine-tuning mechanism includes a base fixed at the upper end of the side wall of the distance fine-tuning mechanism, a movable stopper hinged on the base, and a torsion spring arranged between the base and the movable stopper to drive the movable stopper to expand outward, and the end of the movable stopper is fitted with the inside of the corresponding limiting portion.

[0009] Specifically, a torsion spring is installed at the root of the movable stopper, which makes the movable stopper rotate outward all the time, so that the entire double hook assembly is always in a closed state without external force. When the double hook hanging ring needs to be installed, just press the hanging ring against the movable stopper and lightly press it, and the hanging ring can be installed on the double hook. At the same time, after the external force disappears, the movable stopper in the double hook assembly will be reset under the action of the torsion spring, so that the entire double hook assembly is in a closed state to prevent it from falling off.

[0010] That is, the torsion spring is used to make the movable blocks on both sides of the distance fine-tuning mechanism generate an outward preload force, so that the double hook assembly presents two states of closing and opening under the action of no external force and external force respectively, thereby realizing the rapid clamping of the double hook hanging ring on the double hook.

[0011] Therefore, this solution innovatively designs a method of using a torsion spring to provide a preload force to make the movable stopper close to the double hook assembly, so that the entire double hook assembly is in a normally closed state.

[0012] In one embodiment, a fitting groove that cooperates with the end of the movable stopper is provided on the inner side of each limiting portion.

[0013] In one embodiment, it also includes a main chain, both ends of which are movably connected to two double hook hanging rings, and a U-shaped piece is arranged in the middle of the main chain.

[0014] In one embodiment, the distance fine-tuning mechanism includes an outer sleeve, a middle sleeve and an inner screw. The inner hole of the outer sleeve is provided with an internal thread, and the inner and outer sides of the middle sleeve are provided with threads. The middle sleeve is respectively matched with the outer sleeve and the inner screw threads.

[0015] In one embodiment, the middle sleeve partially extends out of the outer sleeve, and an auxiliary rotation handle is provided on the exterior of the middle sleeve extending out of the outer sleeve.

[0016] In one embodiment, the inner screw rod partially extends out of the middle sleeve, and a connecting hole is provided on the inner screw rod extending out of the middle sleeve.

[0017] In one embodiment, the auxiliary rotating handle is a horizontal connecting rod symmetrically arranged on the outer wall of the middle sleeve.

[0018] In one embodiment, the horizontal connecting rod is detachably connected to the outer wall of the middle casing by a bolt assembly.

[0019] The use process is as follows: the main chain is the pull rope of the wheeled equipment railway transportation tie-down reinforcer;

[0020] Step 1: Take out the pulling rope of the binding reinforcement device. In the initial state, the double hook hanging ring is installed on the double hook assembly;

[0021] Step 2: Press the movable stopper on one side of the double hook assembly to open it, remove the double hook ring from the double hook assembly, and remove the ring on the other side in the same way;

[0022] Step 3: Put the double hook hanging ring and main chain and other components on the axle of the wheeled vehicle equipment that needs to be tied and reinforced;

[0023] Step 4: Place a double hook ring against the movable block and press gently. The double hook ring will slide into the double hook assembly. Use the same method to pass the other double hook ring through the movable block on the other side and install it in the double hook assembly. At this point, the installation of the axle end of the pulling rope is completed.

[0024] The beneficial effects of the utility model are as follows:

[0025] 1. The utility model is reasonably designed. Through the torsion spring, the movable blocks on both sides of the distance fine-tuning mechanism generate an outward preload force, so that the double hook assembly presents two states of closing and opening under the action of no external force and external force respectively, thereby realizing the rapid installation of the double hook hanging ring on the double hook.

[0026] 2. In terms of operating efficiency, compared with the current double hook structure, the utility model can achieve rapid loading and improve the efficiency of bundling operations.

[0027] 3. In terms of labor intensity, compared with the current double hook structure, the utility model has the advantage of being easy to operate and can reduce labor intensity.

[0028] 4. In terms of product, compared with the current double hook structure, the utility model has the characteristics of simple structure, not easy to damage and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Specifically, a torsion spring 5 is installed at the root of the movable stopper 4, and the torsion spring 5 makes the movable stopper 4 always rotate outward, so that the entire double hook assembly 3 is always in a closed state without external force. When the double hook hanging ring 2 needs to be installed, the hanging ring can be installed on the double hook by simply pressing it against the movable stopper 4.
