[0002] At present, horizontal lifting clamps are important lifting tools to ensure the horizontal transportation of metal ingots.

[0003] In the existing system, the left and right jaw seats of the horizontal lifting clamp are the positions where the force is concentrated on the large surface of the ingot. During the long-term lifting process, it is found that the force-bearing steel plates at both ends of the jaw seats are bent and deformed, which easily creates a gap between the jaw surface and the large surface of the ingot, resulting in poor effect of the jaw seats hugging the large surface of the ingot. During the lifting process, serious safety incidents such as the ingot sliding down or falling off are prone to occur. In severe cases, the ingot may fall and injure equipment and personnel. Utility Model Content

[0004] The purpose of the present application is to provide a horizontal lifting clamp and lifting equipment, which solves the problem that the bending deformation at both ends of the jaw seat causes the jaw seat to have a poor effect of hugging the large surface of the ingot.

[0005] To achieve the above-mentioned purpose, the present application provides a horizontal lifting tongs, comprising a tongs arm mechanism and two tongs seats, wherein two ends of the tongs arm mechanism are rotatably connected to the two tongs seats through a first rotating shaft respectively;

[0006] Any jaw seat includes a jaw plate, on which a limiting structure and two support plates are provided. The limiting structure is arranged between the two support plates.

[0008] In some embodiments, the two support plates are symmetrically arranged on both sides of the limiting structure.

[0009] In some embodiments, the jaw tooth plate is provided with two jaw tooth surfaces, and the included angle range of the two jaw tooth surfaces is 165-170°, so that the jaw tooth plate can clamp the straight surface or the curved surface of the workpiece.

A limiting space is formed between each pair of limiting plates, and the limiting space is used to accommodate the jaw ends of the corresponding clamp arm assemblies.

[0011] In some embodiments, a sleeve is provided between two limiting plates on the inner sides of the two clamp arm assemblies, and between any supporting plate and an adjacent limiting plate.

[0012] In some embodiments, the clamp arm assembly includes two clamp arm bodies, and the horizontal lifting clamp further includes a synchronous balance plate, and two ends of the synchronous balance plate are rotatably connected to the two clamp arm bodies through a second rotating shaft.

[0014] In some embodiments, a balancing tension spring is provided between any jaw seat and the jaw arm mechanism to adjust the angle at which the corresponding jaw seat engages the workpiece.

[0015] The present application also provides a lifting device, comprising the horizontal lifting clamp described in any one of the above items.

[0016] Compared with the above-mentioned background technology, the horizontal lifting clamp provided in the embodiment of the present application includes a clamp arm mechanism and two jaw seats, and the two ends of the clamp arm mechanism are rotatably connected with the two jaw seats through a first rotating shaft respectively; further, any jaw seat includes a jaw plate, and the jaw plate is provided with a limiting structure and two support plates, and the limiting structure is arranged between the two support plates. The limiting structure is used to limit the movement of the clamp arm mechanism along the axial direction of the corresponding first rotating shaft, and the limiting structure and the two support plates are provided with through holes for the corresponding first rotating shaft to pass through, and the distance between the two support plates is constructed to be able to reduce the deformation of the jaw plate when the two jaw seats clamp the workpiece.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0036] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the horizontal lifting clamp in the embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the assembly structure of the jaw seat in the horizontal lifting clamp shown.

[0037] The horizontal lifting tongs provided in the embodiment of the present application include a tong arm mechanism 10 and two tong seats 20 , and two ends of the tong arm mechanism 10 are rotatably connected to the two tong seats 20 via a first rotating shaft 30 .

[0038] It should be noted that there are two first rotating shafts 30 and two jaw seats 20, and the first rotating shafts 30 and the jaw seats 20 are rotationally connected one by one. The two ends of the clamp arm mechanism 10 are respectively provided with two first rotating shafts 30 to realize that the two jaw seats 20 are rotationally connected to the two ends of the clamp arm mechanism 10 respectively.

[0039] Furthermore, any jaw seat 20 includes a jaw plate 21, on which a limiting structure 211 and two support plates 212 are provided. The limiting structure 211 is arranged between the two support plates 212. The limiting structure 211 is used to limit the movement of the jaw arm mechanism 10 along the axial direction of the corresponding first rotating shaft 30. The limiting structure 211 and the two support plates 212 are both provided with through holes for the corresponding first rotating shaft 30 to pass through. The distance between the two support plates 212 is constructed to reduce the deformation of the jaw plate 21 when the two jaw seats 20 clamp the workpiece.

[0040] Compared with the traditional setting method in which the two ends of the jaw seat 20 are easily bent and deformed, the horizontal hanging clamp provided in the embodiment of the present application has support plates 212 set at the two end positions of the jaw plate 21. Correspondingly, the two ends of the first rotating shaft 30 extend to the two support plates 212 respectively, and the distance between the two support plates 212 is constructed to reduce the deformation of the jaw plate 21 when the two jaw seats 20 clamp the workpiece.

[0041] In this way, the support of the jaw plate 21 is optimized and the force points of the jaw plate 21 are extended, so that the force on the jaw plate 21 is more balanced, the deformation of the two ends of the jaw plate 21 after the force is applied is reduced, and the problem of poor effect of the jaw seat 20 in hugging the large surface of the ingot caused by the bending deformation at both ends of the jaw seat 20 is solved, thereby extending the service life of the jaw seat 20 and ensuring safe and reliable production needs.

[0042] In some embodiments, any jaw seat 20 also includes two jaw tooth plates 22, which are respectively arranged at the two ends of the jaw plate 21 away from the support plate 212, and the distance between the two support plates 212 is not less than the center distance between the two jaw tooth plates 22.

[0043] It can be understood that the support plate 212 is arranged on the outer side surface of the jaw plate 21, the jaw tooth plate 22 is arranged on the inner side surface of the jaw plate 21, and the two jaw tooth plates 22 are respectively arranged at the two ends of the jaw plate 21, and the distance between the two support plates 212 is greater than or equal to the center distance between the two jaw tooth plates 22.

[0044] Furthermore, the two support plates 212 are symmetrically arranged on both sides of the limiting structure 211 , or in other words, the two support plates 212 are symmetrically arranged about the center of the jaw plate 21 .

[0045] In this way, by optimizing the structure of the jaw plate 21 of the jaw seat 20 and adding a symmetrically arranged support plate 212 to the jaw plate 21, the first rotating shaft 30 can be extended at least to the center position of the jaw tooth plate 22, thereby extending the force point of the jaw plate 21, making the force on the jaw plate 21 more balanced and reducing the deformation of the jaw plate 21 at both ends after being subjected to force.

[0046] In addition, the jaw tooth plate 22 is provided with two jaw tooth surfaces 221, and the two jaw tooth surfaces 221 are arranged at an interval up and down, and the angle range of the two jaw tooth surfaces 221 is 165-170°, so that the jaw tooth plate 22 can clamp the straight surface or curved surface of the workpiece.

[0047] In some embodiments, the included angle of the two jaw tooth surfaces 221 is 168°, ensuring that the jaw seat 20 can be used for ingots with straight or curved surfaces, thereby ensuring that the jaw seat 20 can clamp ingots with straight or curved surfaces and achieve the function of clamping the ingot without slipping.

[0048] In some embodiments, the clamp arm mechanism 10 includes two clamp arm assemblies 11 spaced apart from each other, and the limiting structure 211 includes two pairs of limiting plates. A limiting space is formed between each pair of limiting plates, and the limiting space is used to accommodate the jaw end 112 of the corresponding clamp arm assembly 11.

[0049] Moreover, a sleeve 213 is provided between the two limit plates inside the two clamp arm assemblies 11, and between any support plate 212 and the adjacent limit plate, and the first rotating shaft 30 is passed through the sleeve 213. The sleeve 213 between the two limit plates is used to increase the connection strength between the two limit plates, and the sleeve 213 between the support plate 212 and the adjacent limit plate is used to increase the connection strength between the support plate 212 and the limit plate.

[0050] As a result, in one of the jaw seats 20 , the jaw plate 21 , two support plates 212 , four limit plates and three sleeves 213 form an integral structure, which ensures the overall strength of the jaw seat 20 , thereby further reducing the deformation of the jaw seat 20 .

[0051] Specifically, the clamp arm assembly 11 includes two clamp arm bodies 111 that are staggered, and the horizontal lifting clamp further includes a synchronous balance plate 40 , and two ends of the synchronous balance plate 40 are rotatably connected to the two clamp arm bodies 111 through the second rotating shaft 50 .

[0052] The width of the clamp arm body 111 gradually decreases in a direction away from the jaw end 112, that is, the closer to the jaw end 112 of the clamp arm body 111, the greater the width of the clamp arm body 111, wherein the width of the jaw end 112 gradually decreases in a direction away from the second rotating shaft 50. The clamp arm body 111 is made of high-quality carbon steel Q345, and is cut and processed from an integral steel plate with a thickness of 50 mm, and the angle formed by the clamp arm body 111 and the horizontal line is less than or equal to 16.5°.

[0053] The synchronous balance plate 40 is cut and processed from a 25mm thick integral steel plate of high-quality carbon steel Q345. The main function of the synchronous balance plate 40 is to ensure that the two clamp arm bodies 111 rotate synchronously to open and close outward, and to ensure that the hook and the suspension 60 are located in the center of the large surface of the ingot, so as to ensure that the left and right clamp seats 20 are evenly stressed and safe lifting is guaranteed.

[0054] In some embodiments, the horizontal lifting clamp also includes a suspension 60 and a lifting ring 61 arranged on the suspension 60. The suspension 60 and the lifting ring 61 are made of high-quality carbon steel Q345. The lifting ring 61 is connected to the suspension 60 by a shackle 62. The lifting ring 61 is connected to the hook head of the overhead crane hook and is connected to the suspension 60. The main function is to lift and transport ingots.

[0055] A third rotating shaft 70 is provided at the lower end of the suspension 60, and two spaced-apart pull rod assemblies 80 are provided on the third rotating shaft 70. The two pull rod assemblies 80 are respectively provided at two end positions of the third rotating shaft 70. Any pull rod assembly 80 includes two pull rod bodies 81, and the pull rod body 81 is rotatably connected to the corresponding clamp arm body 111 at one end away from the jaw end 112 through the fourth rotating shaft 90.

[0056] The pull rod body 81 is made of high-quality carbon steel Q345, 25 mm thick integral steel plate cut and processed. The angle between the pull rod body 81 and the corresponding clamp arm body 111 is less than 15°, and the angle between the pull rod body 81 and the lifting ring 61 is less than 120°.

[0057] The main function of the pull rod assembly 80 is that when the jaw seat 20 clamps the ingot, the pull rod body 81 and the clamp arm body 111 are stretched upward to form a scissors clamping structure, and the ingot is lifted synchronously with the overhead crane.

[0058] In addition, the horizontal lifting clamp also includes a closer 110 , the upper end of which is connected to the bottom of the suspension 60 , and the lower end (locking tongue) of the closer 110 is adapted to a locking seat, which is fixed between the steel plates on the inner sides of the two synchronous balance plates 40 .

[0059] Specifically, the closer 110 uses a standard 10-ton closer 110, which can realize the automatic hooking (unhooking) function. When unloaded, the locking tongue of the rotating shaft of the closer 110 and the locking seat are in a locked state. When the ingot needs to be held tightly, the rotating shaft of the closer 110 rotates 90°, and the locking tongue automatically disengages from the locking seat (equivalent to the rotating shaft rising, the pull rod body 81 and the clamp arm body 111 are stretched upward and stressed), the jaw seat 20 is closed, and the jaw tooth surface 221 holds the ingot tightly, and the ingot is lifted under the operation of the overhead crane. The structure of the closer 110 can refer to the content of the prior art, and will not be expanded here one by one.

[0060] In some embodiments, a balancing tension spring 100 is provided between any jaw seat 20 and the jaw arm mechanism 10 to adjust the angle at which the corresponding jaw seat 20 engages the workpiece.

[0061] It should be noted that the left and right jaw seats 20 and the balance spring 100 are mainly used to clamp the ingot and support the force, and the ingot is clamped by the friction force formed by the weight of the ingot and the jaw tooth surface 221. The balance spring 100 is mainly used to adjust the angle of the jaw seat 20 to hold the ingot, ensuring that all the teeth on the jaw tooth surface 221 are in contact with the ingot surface, thereby ensuring the clamping force and preventing the ingot from slipping.

[0062] The present application provides a lifting equipment, including the horizontal lifting clamp described in the above specific embodiment; other parts of the lifting equipment can refer to the relevant technology and will not be elaborated in this article.

[0063] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0064] The horizontal lifting clamp and lifting equipment provided by the present application are introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the present application. The description of the above embodiments is only used to help understand the scheme and its core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the present application.
