[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figure 1-6, the present utility model provides a technical solution: an automatic hook device for a railway shunting locomotive, including an automatic hook device main body 1. An adjustment seat 4 is provided on the automatic hook device main body 1, and a threaded hole 401, a limit hole 402 and a plug hole 403 are opened on the adjustment seat 4. And an adjustment screw 3, a limit rod 12 and a hook positioning seat 5 respectively penetrate through the threaded hole 401, the limit hole 402 and the plug hole 403. The hook positioning seat 5 is of a T-shaped structure, and a spring seat 13 is movably sleeved outside the installation box 8 on the hook positioning seat 5. This structure can prevent the hook positioning seat 5 from falling off relative to the adjustment seat 4 through the T-shaped structure of the hook positioning seat 5. The spring seat 13 moves on the hook positioning seat 5 and can cooperate with the shock absorption treatment of the shock absorption spring 6. An end shock absorption spring 6 is sleeved and fixed on the hook positioning seat 5, and the shock absorption spring 6 is located between the spring seat 13 and the end of the hook positioning seat 5. This structure can limit the movement of the hook positioning seat 5 relative to the adjustment seat 4 through the shock absorption spring 6, so that when the railway shunting locomotive performs traction shunting through the automatic hook device main body 1, it can play a role of shock absorption and protection. The hook positioning seat 5 is horizontally arranged, and the hook positioning seat 5 is located between the adjustment screw 3 and the limit rod 12, and the hook positioning seat 5 is vertically arranged relative to the adjustment screw 3 and the limit rod 12. This structure avoids the influence of the tension received by the hook positioning seat 5 on the adjustment seat 4, thereby preventing the adjustment screw 3 and the limit rod 12 from being over-pulled and deformed. And the adjustment screw 3 and the limit rod 12 are arranged in parallel. One end of the hook positioning seat 5 is connected with an outer end plate 501, and a hook installation seat 9 is fixed outside the outer end plate 501. An installation box 8 is provided on the automatic hook device main body 1, and connecting plates 2 and limit plates 7 are respectively screwed and fixed on two opposite long sides of the installation box 8. And the adjustment screw 3 and the limit rod 12 are respectively installed in the installation box 8. This structure can install and position the adjustment screw 3 and the limit rod 12 through the installation box 8, and the limit rod 12 limits the movement of the adjustment seat 4 to ensure the smooth movement of the adjustment seat 4. One end of the adjustment screw 3 is connected to a motor through a coupling, so that during the rotation of the adjustment screw 3, the rotational movement of the adjustment screw 3 can be converted into a linear movement of the adjustment seat 4, thereby realizing the adjustment of the position of the hook positioning seat 5 through the movement of the adjustment seat 4, and further realizing the adjustment of the position of the hook 10. The connecting plate 2 can be screwed and fixed to the railway shunting locomotive to realize the connection and fixation of the automatic hook device main body 1 and the railway shunting locomotive. The limit plate 7 is of a U-shaped structure, and the outer end plate 501 is movably clamped in the U-shaped structure of the limit plate 7. A limit groove 701 is opened on the limit plate 7, and the limit groove 701 is movably clamped with the hook positioning seat 5. This structure can perform a movement limit treatment on the outer end plate 501 through the limit plate 7, and the limit groove 701 is used for the movement limit treatment of the hook positioning seat 5. A hook 10 and a hook adjustment hydraulic cylinder 11 are rotatably installed on the hook installation seat 9, and the movable end of the hook adjustment hydraulic cylinder 11 is also connected to the side of the hook 10 through a pin. An anti-detachment member 901 is integrally provided on the hook installation seat 9.Moreover, the anti-detachment member 901 is engaged and fitted with the opening part of the hook 10.
[0021] Working principle: When using the automatic hook device of the railway shunting machine, first, the main body 1 of the automatic hook device is fixed on the railway shunting machine through the connecting plate 2. When the railway shunting machine performs automatic hook processing through the main body 1 of the automatic hook device, if the position of the hook 10 is not accurately aligned, the motor for driving the rotation of the adjusting screw 3 can be started, so that the adjusting screw 3 drives the adjusting seat 4 to move linearly through the cooperation of the threaded hole 401. The adjusting seat 4 is movably limited through the cooperation of the limiting hole 402 and the limiting rod 12. The installation box 8 plays a role in installing and positioning the adjusting screw 3 and the limiting rod 12. The hook positioning seat 5 moves along with the movement of the adjusting seat 4, so that the hook 10 moves to a position where it can be hooked. The limiting groove 701 also performs movably limiting processing on the hook positioning seat 5. The limiting plate 7 is clamped and stabilized on the outer end plate 501 through a U-shaped structure to ensure the stable movement of the outer end plate 501. Then, the hook adjusting hydraulic cylinder 11 is started to make the hook 10 rotate relative to the hook mounting seat 9 to open the hook 10. After the hook 10 hooks the equipment, the hook 10 rotates and closes again. At this time, the opening end of the hook 10 catches the anti-detachment member 901 for anti-detachment processing. At the same time, the hook positioning seat 5 moves relative to the adjusting seat 4 through the insertion hole 403, so that the hook mounting seat 9 connected to the hook positioning seat 5 through the outer end plate 501 can move back and forth relative to the adjusting seat 4, enabling the hook 10 to perform shock absorption processing of moving back and forth under the cooperation of the shock absorption spring 6 and the spring seat 13, ensuring the shock absorption and protection during shunting, and during the process of the railway shunting machine performing traction shunting, making the hook 10 move to the central position again to ensure the balance of the pulling force, thereby completing a series of operations.
