In these fields, crane hooks are key components for material handling and are used in daily hoisting operations.
[0003] Currently, when a crane lifts a heavy object using its hook, if the object is too heavy, the hook rope may break when it is lifted to a higher position, causing the object to fall and posing a significant safety hazard to construction. Utility Model Content
[0004] To address the problems in the prior art, this utility model provides a crane hook assembly capable of real-time monitoring of load weight.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A crane hook assembly capable of real-time monitoring of load weight includes a connecting seat, a hook body fixed to one side of the bottom of the connecting seat, one side of the hook body being open, an inner slide rail being provided inside the hook body below the connecting seat, a limiting slide rail being provided between the inner walls of the two sides of the inner slide rail, a sealing slider being slidably sealed between the inner walls of the limiting slide rail, an inner sliding plate being provided between the inner walls of the limiting slide rail, one end of the inner sliding plate being fixed to one side of the sealing slider, and two upright plates being fixed to the top of the connecting seat, with a threaded rod being provided between the two upright plates.
[0007] Optionally, the hook body has an inner cavity located above the inner slide rail. A sealing plate is slidably disposed between the inner walls of the inner cavity, and a pad is fixed to the top of the sealing plate.
[0008] Optionally, the top of the pad block slides through to the inside of the hook body, and an arc-shaped contact plate is fixed to the top of the pad block, the arc-shaped contact plate being located below the inside of the hook body.
[0009] Optionally, the connecting seat has an adjustment cavity inside, and the bottom surface of the adjustment cavity has a bottom groove, the bottom of which is concave.
[0010] Optionally, a throttling channel is provided on the inner bottom surface of the bottom groove. The throttling channel extends through the inside of the hook body, and one end of the throttling channel is connected to one side of the inner wall of the inner cavity near the bottom edge.
[0011] Optionally, a limiting ring is fixed at the middle between the inner walls of the adjusting cavity, and a bend is provided on one side of the inner wall of the inner slide, with one end of the bend extending through to the inside of the limiting ring.
[0012] Optionally, a transparent scale plate is fixed to one side of the inner wall of the adjustment cavity at the bottom edge, and one end of the transparent scale plate extends to the outside of the connecting seat.
[0013] Optionally, guide grooves are provided on both sides of the inner wall of the adjustment cavity above the limiting ring, and an inner sealing plate is provided between the inner walls of the adjustment cavity for sliding sealing.
[0014] Optionally, guide blocks that are slidably sealed and connected inside the guide groove are fixed on both sides of the inner sealing plate, and an adjusting screw is rotatably provided on the top of the inner sealing plate, with the top thread of the adjusting screw extending through to the top of the connecting seat.
[0015] Optionally, a circular plate is slidably sealed between the inner walls of the adjustment cavity near the bottom edge, and a spring is fixed between the top of the circular plate and the bottom of the inner sealing plate. A push plate is slidably disposed between the inner walls of the bottom groove near the bottom edge.
[0016] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time:
[0017] 1. In this utility model, when the hook body lifts a heavy object and the object leaves the bottom surface, the weight of the object on the hook body will press down on the arc-shaped contact plate, causing the pad and sealing plate to slide downwards into the inner cavity. During the sliding process, the hydraulic oil in the inner cavity will be pushed into the bottom groove through the throttling channel. When pushing, the hydraulic oil in the bottom groove will be pushed into the adjustment cavity through the push plate, and the circular plate will be pushed upwards into the adjustment cavity. The operator can determine the weight of the object by observing the scale position of the circular plate and the transparent scale plate from the outside. This prevents the lifting rope and hook from malfunctioning after the object is lifted to a high altitude due to overweight, which could cause the object to fall.
[0018] 2. In this utility model, when the circular plate slides upward, the hydraulic oil inside the adjustment cavity will be pushed into the inner slide through the bending channel, thereby pushing the sealing slider and causing one end of the inner slide plate to slide towards the opening of the hook body, closing the opening and preventing the object from slipping after being lifted.

[0030] According to some embodiments of this solution, a crane hook assembly capable of real-time monitoring of load weight is provided, for reference. Figures 1-4 As shown, the crane hook assembly capable of real-time monitoring of load weight includes a connecting seat 1. A hook body 2 is fixed to one side of the bottom of the connecting seat 1. One side of the hook body 2 is open. An inner slide 5 is provided inside the hook body 2 below the connecting seat 1. A limiting slide 8 is provided between the inner walls of the two sides of the inner slide 5. A sealing slider 9 is provided between the inner walls of the limiting slide 8. An inner sliding plate 6 is provided between the inner walls of the limiting slide 8. One end of the inner sliding plate 6 is fixed to one side of the sealing slider 9. Two upright plates 3 are fixed to the top of the connecting seat 1. A threaded rod 4 is provided between the two upright plates 3.
[0031] Please see Figures 1-4 The hook body 2 has an inner cavity 10 inside, which is located above the inner slide 5. A sealing plate 11 is slidably arranged between the inner walls of the inner cavity 10, and a pad 12 is fixed on the top of the sealing plate 11.
[0032] The top of the pad 12 slides through to the inside of the hook body 2, and an arc-shaped contact plate 7 is fixed on the top of the pad 12. The arc-shaped contact plate 7 is located below the inside of the hook body 2.
[0033] The connecting seat 1 has an adjustment cavity 15 inside, and the bottom surface of the adjustment cavity 15 has a bottom groove 23, the bottom of the bottom groove 23 is concave.
[0034] A throttling channel 13 is provided on the inner bottom surface of the bottom groove 23. The throttling channel 13 passes through the inside of the hook body 2, and one end of the throttling channel 13 is connected to the inner wall of the inner cavity 10 near the bottom edge.
[0035] A limiting ring 21 is fixed in the middle between the inner walls of the adjusting cavity 15. A bend 14 is provided on one side of the inner wall of the inner slide 5, and one end of the bend 14 extends through to the inside of the limiting ring 21.
[0036] A transparent scale plate 25 is fixed to one side of the inner wall of the adjustment cavity 15 at the bottom edge, and one end of the transparent scale plate 25 extends to the outside of the connecting seat 1.
[0037] Guide grooves 17 are provided on both sides of the inner wall of the regulating cavity 15 above the limiting ring 21, and an inner sealing plate 19 is provided between the inner walls of the regulating cavity 15 for sliding sealing.
[0038] In addition, guide blocks 18 are fixed on both sides of the inner sealing plate 19 and are slidably sealed inside the guide groove 17. An adjusting screw 16 is rotatably provided on the top of the inner sealing plate 19. The top of the adjusting screw 16 is threaded through to the top of the connecting seat 1. A circular plate 22 is slidably sealed between the inner walls of the adjusting cavity 15 near the bottom edge. A spring 20 is fixed between the top of the circular plate 22 and the bottom of the inner sealing plate 19. A push plate 24 is slidably provided between the inner walls of the bottom groove 23 near the bottom edge.
[0039] Through the above technical solution, the crane hook assembly that can monitor the load weight in real time provided by this solution changes the position of the inner sealing plate 19 between the inner wall of the adjustment cavity 15 by rotating the adjusting screw 16, thereby changing the clamping force on the spring 20.
[0040] When no heavy object is being lifted inside the hook body 2, the circular plate 22 is located on the bottom surface inside the adjustment cavity 15, the push plate 24 is located on the bottom surface inside the bottom groove 23, and the adjustment cavity 15, the bottom groove 23, the inner cavity 10 and the inner slide 5 are all filled with hydraulic oil on the side of the sealing slider 9. At this time, one end of the inner slide plate 6 is located inside the opening of the hook body 2, and the sealing plate 11 is located on the top surface inside the inner cavity 10.
[0041] When the hook body 2 lifts the heavy object and the object leaves the bottom surface, the weight of the object on the hook body 2 will press down on the arc-shaped contact plate 7, causing the pad 12 and sealing plate 11 to slide downwards into the inner cavity 10. During the sliding process, the hydraulic oil in the inner cavity 10 will be pushed into the bottom groove 23 through the throttle channel 13. When pushing, the hydraulic oil in the bottom groove 23 will be pushed into the adjustment cavity 15 through the push plate 24, and the circular plate 22 will be pushed upwards into the adjustment cavity 15. The operator can determine the weight of the object by observing the scale position of the circular plate 22 and the transparent scale plate 25 from the outside, which prevents the lifting rope and hook from malfunctioning after the object is lifted to a high altitude due to overweight, causing the object to fall.
[0042] Furthermore, when the circular plate 22 slides upward, it pushes the hydraulic oil inside the adjusting cavity 15 into the inner slide 5 through the bending channel 14, thereby pushing the sealing slider 9 and causing one end of the inner slide plate 6 to slide towards the opening of the hook body 2, sealing the opening and preventing the object from slipping after lifting.

[0045] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
