Description

Technical Field

[0001] The utility model relates to the field of hoisting slings, in particular to a sling for hoisting graphite plates. Background Art

[0002] At present, the sling used for hoisting graphite plates is a sling, which is prone to be cut by the edge of the graphite plate during use. And the operation is cumbersome during use. It needs to be inserted from the bottom of the plate as a whole, increasing the operation risk and intensity, and prone to safety accidents such as the plate slipping. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sling for hoisting graphite plates to solve the above problems.

[0004] To achieve the above purpose, the following technical solutions are provided:

[0005] A sling for hoisting graphite plates, which is used in cooperation with graphite plates, includes a clamping mechanism and a lifting mechanism. The clamping mechanism includes clamping teeth, a clamping shaft and a positioning groove. The positioning groove is of a "concave" structure and is arranged upside down. There are two clamping teeth, which respectively penetrate through both sides of the positioning groove and are hinged through the clamping shaft. One end of the clamping teeth where they clamp the graphite plate is set to be arc-shaped;

[0006] The lifting mechanism includes a clamping tongue, lifting lugs, connecting bolts, lifting ropes and lifting rings. There are two clamping tongues, which are respectively fixedly connected to one end of the two clamping teeth. There are two lifting lugs, which are respectively arranged at the other end of the clamping tongue. The lifting lugs are hinged to the clamping tongue through the connecting bolts. One lifting rope is sleeved on the top of each lifting lug and can slide relative to it. The other ends of the lifting ropes are respectively sleeved on the lifting rings and can slide relative to them;

[0007] Preferably, the width inside the positioning groove is greater than that of the graphite plate, and a first buffer pad is arranged inside the positioning groove;

[0008] Preferably, a second buffer pad penetrates through the positioning groove and the first buffer pad at the arc-shaped position of the clamping teeth, and a plurality of protrusions are arranged on its surface;

[0009] Preferably, both the first buffer pad and the second buffer pad are made of rubber.

[0010] The beneficial effects of the utility model are as follows:

[0011] When hoisting a graphite plate with this sling for hoisting graphite plates, the lifting rope is connected to the clamping tongue, and the positioning groove and the clamping teeth clamp the graphite plate. During the process of lifting and applying force upward, the clamping teeth and the plate will be firmly fixed, which depends on the lever interaction force between the clamping teeth and the plate. After the hoisting is completed, automatic unhooking can be realized. Since the graphite plate is made of soft material and is easily damaged during hoisting, the second buffer pad provided at the end of the clamping teeth plays a role of buffering and increasing the friction force.

[0012] Figure 1 is a structural schematic diagram of the present utility model;

[0013] Figure 2 is a structural schematic diagram of the tong tongue and the tong teeth of the present utility model;

[0014] The reference numerals shown in the drawings are: 1 tong tongue, 10 tong teeth, 2 tong shaft, 3 positioning groove, 4 lifting lug, 5 connecting bolt, 6 lifting rope, 7 lifting ring, 8 first buffer pad, 80 second buffer pad, 81 protrusion, 9 graphite plate. Detailed Implementation Manner

[0015] The following is a detailed description of this design solution in conjunction with the drawings:

[0016] As Figure 1-2 shown, a lifting tool for lifting graphite plates includes a clamping mechanism and a lifting mechanism. The clamping mechanism includes tong teeth 10, a tong shaft 2, and a positioning groove 3. The positioning groove 3 has a "concave" structure and is arranged upside down. There are two tong teeth 10, which are respectively arranged on both sides of the positioning groove 3 and are hinged through the tong shaft 2. The other end of the tong teeth 10 is set to be arc-shaped at the clamping position of the graphite plate, which is convenient for clamping the graphite plate 9 and can achieve automatic hook release;

[0017] The lifting mechanism includes a tong tongue 1, lifting lugs 4, connecting bolts 5, lifting ropes 6, and lifting rings 7. There are two tong tongues 1, which are respectively fixedly connected to one end of the tong teeth 10. There are two lifting lugs 4, which are respectively arranged at the other end of the tong tongue 1. The lifting lugs 4 are hinged to the tong tongue 1 through the connecting bolts 5. A lifting rope 6 is sleeved on the top of each lifting lug 4 and can slide relative to it. The other ends of the lifting ropes 6 are respectively sleeved on the lifting rings 7 and can slide relative to them;

[0018] In some embodiments, the width inside the positioning groove 3 is slightly larger than that of the graphite plate. An elastic first buffer pad 8 is provided inside the positioning groove 3, and the clamping action will not cause scratches to the graphite plate 9, preventing damage to the graphite plate 9;

[0019] In some embodiments, a second buffer pad 80 is fixedly installed at the arc-shaped position of the tong teeth 10, and a plurality of protrusions 81 are provided on its surface, which can further enhance the clamping effect, increase the friction force, and reduce the impact force of the collision of the graphite plate 9;

[0020] In some embodiments, both the first buffer pad 8 and the second buffer pad 80 are made of rubber material, which play a role of buffering and shock absorption during lifting.

[0021] Working Principle:

[0022] Combined with Figure 1-2As shown in the figure, the working principle and usage process of the present utility model are as follows: When the graphite plate needs to be hoisted, align the opening position of the positioning groove 3 with the top of the graphite plate and let it fall. During the falling process, the top of the graphite plate 9 touches the clamping teeth 10, and the clamping teeth 10 rotate outward with the clamping shaft 2 as the axis, so that the graphite plate 9 can smoothly enter the positioning groove 3, and then it is hoisted.

[0023] Combined with Figure 1-2 As shown in the figure, during hoisting, the lifting ring 7 drives the lifting rope 6 to lift upward, the lifting rope 6 drives the lifting lug 4 to lift, the lifting lug 4 is hinged to the connecting bolt 5, and then drives the clamping tongue 1 to rotate inward. The clamping tongue 1 drives the upper arc position of the clamping teeth 10 to clamp the graphite plate 9 through the clamping shaft 2. A buffer pad 802 and multiple protrusions 81 are installed at the upper arc position of the clamping teeth 10 to prevent the graphite plate 9 from being damaged and increase the friction force. After the hoisting is completed, automatic unhooking can be realized through the clamping teeth 10 and the clamping shaft 2.
