TECHNICAL FIELD

[0001] The utility model belongs to the automatic technology field of dumper system, specifically is a empty car promotes the hook device. BACKGROUND

[0002] Although the dumper system has realized automatic operation in many aspects, manual operation is still needed before and during the operation of the dumper system. For example, manual work is needed to ventilate the open car, remove the air pipe, and pull out the car before operation. Manual work is needed to remove the hook of the open car during the operation of the dumper, and workers need to enter the dumper equipment to complete the work. Considering that the car, the car mover, the dumper, and the car moving platform are moving during the unloading process of the dumper, there is a safety hazard of mechanical injury when manual operation is performed, and it is more likely to cause mechanical injury at night due to the influence of the environment on the line of sight. In addition, long-term work in a dusty environment will cause irreversible damage to the worker's body.

[0003] Based on the above problems, a kind of empty car promotes the hook device, by robot drive promotes the hook movement, to realize the open car of hooking operation. CONTENT OF THE UTILITY MODEL

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a kind of empty car promotes the hook device, effectively solve the problem raised in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a kind of empty car promotes the hook device, including connecting flange, the one end welding of connecting flange has promoted hook piece, promotes hook piece and include hook arm and hook head, hook arm is welded with connecting flange, and hook head is welded with hook arm.

[0006] Preferably, the hook arm is arranged in a right-angle trapezoidal structure.

[0007] Preferably, the hook head is arranged in an upward spiral shape.

[0008] Preferably, the one end of the connecting flange is provided with a positioning groove, and the one end of the hook arm is located in the positioning groove. The surface of the connecting flange is provided with a fixing hole.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] 1、the utility model discloses that the hook device is installed and cooperates with robot, through the movement operation of robot, reduces the manual direct participation of hooking operation of dumper system, effectively reduces the harm of mechanical injury and dust to worker's health, significantly improves the operation efficiency, shortens the operation cycle of dumper system;

[0011] 2. This new type of purely mechanical structure design is simple in structure, has low maintenance costs, and is easy to inspect and replace damaged parts. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figures 1-7 As shown, this utility model includes a connecting flange 1, and a lifting hook 2 is welded to one end of the connecting flange 1. The lifting hook 2 includes a hook arm 21 and a hook head 22. The hook arm 21 is welded to the connecting flange 1, and the hook head 22 is welded to the hook arm 21.

[0024] The hook arm 21 is arranged in a right-angled trapezoidal structure.

[0025] The hook head 22 is arranged in an upward spiral shape.

[0026] One end of the connecting flange 1 is provided with a positioning groove 3, and one end of the hook arm 21 is located in the positioning groove 3. The surface of the connecting flange 1 is provided with a fixing hole 4 for installation with the mechanical arm of the robot.

[0027] Working principle:

[0028] The hook device is connected with the mechanical arm of the robot, and the hook device reaches the specified position through the Y-axis, X-axis and Z-axis movement of the robot.

[0029] When the hook is lowered, the hook head 22 hooks the opening and closing rod of the car Jan type car hook by using the self-locking principle, and then the mechanical arm makes a rotating circular arc movement to realize the hook lifting action. When the hook is lifted, the hook head 22 also hooks the opening and closing rod, and the hook head 22 rotates to complete the hook lifting (such as Figure 4 , Figure 5 , Figure 6 ); After the hook lifting action is completed, the robot drives the hook head 22 to automatically reset the car Jan type car hook tongue by using the shape characteristics of the hook head 22 (such as Figure 7 ).
