AI Technical Summary
The existing super-large sky truck hooks are prone to collision with relevant personnel when operating at the lowest level, resulting in safety hazards.
An integrated super-large sky-car hook is designed, using components such as rotating joints, hook return springs, reset limit pins, collision rods, collision return springs, collision touch switches and RFID identifiers to form an anti-collision device and workpiece positioning mechanism to ensure that the hook avoids collision when running at the lowest position.
By configuring a rotating joint and a hook reset spring, the hook can adapt to greater positioning errors and realize the water pouring of the cavity workpiece; the RFID identifier ensures accurate positioning; the built-in anti-collision device not only prevents the driving pickup from being over-positioned, but also prevents the hook from colliding with relevant personnel when it is running at the lowest position, improving safety.

Abstract
Description
Technical Field
[0001] The invention relates to the field of super-large overhead cranes, and in particular to an integrated hook for super-large overhead cranes. Background Art
[0002] An extra-large overhead crane is a lifting device that is horizontally mounted above workshops, warehouses and material yards to lift materials. A necessary part of lifting equipment is the hook. Existing hooks are prone to collision with relevant personnel when running at the lowest position.
[0003] Therefore, it is necessary to design an anti-collision integrated oversized overhead crane hook. Summary of the invention
[0004] The technical problem to be solved by the present invention is that the existing hook is easy to collide with relevant personnel when running at the lowest position.
[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide an integrated super-large overhead crane hook, the hook includes a hook frame and a pair of hook bodies, a rotating joint is installed on the hook frame, and the hook body is fixedly connected to the rotating joint.
[0006] A hook reset spring is fixedly connected to the bottom of the hook frame, and the other end of the hook reset spring is fixedly connected to the hook body.
[0007] A reset limit pin is fixedly installed at the bottom of the hook frame, and the reset limit pin is located below the reset spring.
[0008] A pair of collision rods are fixedly installed at the bottom of the hook bodies, and collision reset springs are fixedly connected to both ends of the collision rods. The other end of the collision reset spring is fixedly connected to the outer side wall of the hook body.
[0009] A switch rod is fixedly installed between the pair of hook bodies, and a collision trigger switch is fixedly installed on the front side of the switch rod.
[0010] An RFID identifier is fixedly installed on the front side of the hook body.
[0011] The beneficial effects of the present invention are as follows:
[0012] The configuration of rotating joints and hook reset springs can adapt to larger positioning errors and realize the pouring action of cavity workpieces; it is also equipped with an RFID identifier as a workpiece positioning mechanism to ensure accurate positioning; the built-in anti-collision device as a safety mechanism can not only prevent the driving to pick up the parts from going over the position, but also prevent the hook from colliding with relevant personnel when running at the lowest position. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In the figure: 1. hook reset spring; 2. reset limit pin; 3. hook body; 4. RFID identifier; 5. collision trigger switch; 6. collision rod; 7. collision reset spring; 8. rotating joint; 9. hook frame. DETAILED DESCRIPTION
[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0017] See also Figure 1-2 The hook comprises a hook frame 9 and a pair of hook bodies 3 , a rotary joint 8 is mounted on the hook frame 9 , and the hook body 3 is fixedly connected to the rotary joint 8 .
[0018] A hook reset spring 1 is fixedly connected to the bottom of the hook frame 9 , and the other end of the hook reset spring 1 is fixedly connected to the hook body 3 .
[0019] A reset limit pin 2 is fixedly installed at the bottom of the hook frame 9, and the reset limit pin 2 is located below the reset spring 1.
[0020] A collision rod 6 is fixedly installed at the bottom of a pair of hook bodies 3 , and collision reset springs 7 are fixedly connected to both ends of the collision rod 6 . The other end of the collision reset spring 7 is fixedly connected to the outer side wall of the hook body 3 .
[0021] A switch rod is fixedly installed between a pair of hook bodies 3, and a collision trigger switch 5 is fixedly installed on the front side of the switch rod.
[0022] An RFID identifier 4 is fixedly mounted on the front side of the hook body 3 .
[0023] Working principle:
[0024] Hook rotation and reset:
[0025] The hook body 3 can rotate counterclockwise at a small angle (approximately Max. 7°) through the rotating joint 8. When resetting, the hook reset spring 1 and the hook body 3 itself cooperate with the reset limit pin to restore to the original (vertical) position;
[0026] Hook horizontal positioning:
[0027] When the crane is in horizontal operation, the corresponding workpiece is identified by the RFID identifier 4 to stop the crane at the corresponding position. After reading the relevant information correctly, the next step is carried out (horizontal over-position mechanism: when the crane is in horizontal over-position, the collision rod 6 collides with the hard limit, thereby triggering the collision trigger switch 5, causing the crane to stop urgently and alarm; only after manual intervention to release the alarm, the collision rod 6 returns to its original position through the collision reset spring 7).
[0028] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
