Description

Technical Field

[0001] The present application relates to the technical field of plate lifting and rotating processing, and in particular to an easily disassembled plate lifting fixture. Background Art

[0002] Currently, sheet metal processing usually includes the following steps:

[0003] Cutting: refers to cutting the plate into the required size. Common cutting methods include planing, shearing, spark cutting, etc.

[0004] Forming: It is to process metal sheets into the desired shape. Common forming methods include stamping, bending, stretching, etc.

[0005] Welding: Welding operations are performed on metal sheets to connect different sheet components together. Common welding methods include manual welding, gas shielded welding, arc welding, etc.

[0006] Detail processing: such as deburring, polishing, spraying, etc., detail processing can further improve the appearance quality and performance of metal products.

[0007] Inspection and quality control: Finally, the processed metal sheets need to be inspected to check whether their size, shape and quality meet the requirements.

[0008] At present, the processing of metal plates involves multiple process steps and equipment. The plates need to be transferred between different processes. The most convenient and fastest way to lift the plates is to use the following method as shown in the attached manual. Figure 1-3 The lifting fixture shown in the figure is used for transfer. The lifting fixture includes an L-shaped lifting plate, which is composed of a vertical plate and a horizontal plate. A pressure plate is inserted and hinged on the vertical plate, and a lifting rope inserted from the top of the vertical plate is connected to the top of the pressure plate. When lifting the plate, a pair of the fixtures are selected to lift from both sides of the plate. When lifting, the pressure plate is hinged open, and the horizontal plate is inserted to the bottom of the plate. Then, the lifting rope is used to lift it up, driving the pressure plate to rotate, so that the bottom end of the pressure plate presses the side of the plate against the horizontal plate, as shown in FIG. Figure 2 As shown, the rapid lifting operation of the plate can be achieved.

[0009] At present, after the plate is transferred to the next process by the above-mentioned lifting fixture, the plate will press the fixture as a whole onto the operating platform or the ground. Figure 3 As shown, the metal sheet is usually heavy, making it difficult to smoothly separate the clamp from the sheet (such as Figure 3 Therefore, operators usually use kicking or other methods to separate the clamp from the sheet (such as Fig.11It is not only physically demanding, but also poses a safety hazard of impact injury, making the transfer cycle of the sheet metal between various processes too long, affecting the processing efficiency of the sheet metal. Summary of the invention

[0010] In response to the above-mentioned problems, the present application aims to provide an easily disassembled plate lifting clamp, which is provided with a rolling mechanism. The rolling mechanism allows the plate to be rolled away from the upper surface of the horizontal plate, thereby solving the current problem that the plate is flat against the upper surface of the horizontal plate, resulting in large contact friction and difficulty in smooth separation, as well as the problem that the bottom surface of the horizontal plate is difficult to separate from the ground.

[0011] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: an easily disassembled plate lifting clamp, which comprises an L-shaped lifting plate, which is composed of a vertical plate and a horizontal plate, a pressure plate is passed through and hinged on the vertical plate, and a lifting rope passed through the top side of the vertical plate is connected to the top side of the pressure plate, characterized in that: rolling mechanisms protruding from the surface are provided on the upper and lower surfaces of the horizontal plate, and the rolling mechanism on the upper surface of the horizontal plate can be adjusted to extend out of the surface or retract below the surface.

[0012] Preferably, the rolling mechanism is a roller wheel which is evenly spaced apart on the upper and lower sides of the horizontal plate, and the top surface of the roller wheel protrudes from the upper and lower surfaces of the horizontal plate.

[0013] Preferably, the rollers arranged on the upper and lower sides of the horizontal plate are staggered in the horizontal direction.

[0014] Preferably, a groove for embedding the rotating shaft of the roller and adjusting the height of the rotating shaft is provided on the upper surface of the horizontal plate, and an adjusting screw for driving the rotating shaft to move up and down is provided on the side wall of the horizontal plate.

[0015] The beneficial effect of the present application is that the clamp disclosed in the present application is provided with a rolling mechanism, which enables the plate and the upper surface of the horizontal plate to be rolled away, thereby solving the current problem that the plate and the upper surface of the horizontal plate are flat with large contact friction and difficult to separate smoothly, as well as the problem that the bottom surface of the horizontal plate is difficult to separate from the ground.

[0016] The rolling mechanism on the upper surface of the horizontal plate can be adjusted to extend out of the surface or retract to an adjustable structure below the surface, which can ensure the stability of the plate clamping when lifting the plate; and when the plate is separated from the clamp, the rolling separation effect is realized, thereby ensuring the safety of the plate lifting process while making the clamp easy to separate.

[0029] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0030] See attached Figures 1 to 10 The illustrated is an easily disassembled plate lifting fixture, which includes an L-shaped lifting plate 1, which is composed of a vertical plate 11 and a horizontal plate 12. A pressing plate 2 is passed through and hinged on the vertical plate 11, and a lifting rope 3 passed through the top side of the vertical plate 11 is connected to the top side of the pressing plate 2. When lifting the plate, a pair of the fixtures are selected to lift from both sides of the plate, the pressing plate 2 is hinged open, the horizontal plate 12 is passed through the bottom of the plate, and then the lifting rope 3 is used to lift it up, driving the pressing plate 2 to rotate, so that the bottom end of the pressing plate 2 presses the side of the plate against the horizontal plate 12, as shown in FIG. Figure 2 As shown, the rapid lifting operation of the plate can be achieved.

[0031] In order to solve the problem that it is difficult to smoothly separate and disassemble the clamp from the plate after the plate is lifted and transported, the present application provides a rolling mechanism protruding from the surface on the upper and lower surfaces of the horizontal plate 12, and the rolling mechanism allows the plate and the upper surface of the horizontal plate 12 to be rolled away, thereby solving the problem that the plate and the upper surface of the horizontal plate 12 are currently flat against each other, having large contact friction and being difficult to separate smoothly.

[0032] Similarly, the rolling mechanism arranged on the bottom surface of the horizontal plate 12 can enable the horizontal plate 12 to roll away from the ground or the equipment operating table, thereby achieving the overall smooth separation of the horizontal plate 12 from the transferred plate, shortening the plate transfer cycle, improving the plate processing efficiency, and at the same time improving the safety of the clamp disassembly.

[0033] The contact between the plate and the rolling mechanism will reduce the surface contact friction between the plate and the horizontal plate 12, and thus there will be a safety hazard of the plate and the horizontal plate 12 slipping and falling during the lifting and transportation process. Therefore, to solve this problem, the rolling mechanism on the upper surface of the horizontal plate 12 can be adjusted to extend out of its surface or retract below the surface, that is, when the plate is lifted, the rolling mechanism on the upper surface retracts below the surface, so that the plate is in flat contact with the surface of the horizontal plate 12; and when the plate is separated from the clamp, the rolling mechanism is driven to extend out of the upper surface of the horizontal plate 12 to achieve the effect of rolling separation, thereby ensuring the safety of the plate during lifting while making the clamp easy to separate.

[0034] Specifically, Figure 4 As shown, the rolling mechanism is rollers 4 arranged at equal intervals on the upper and lower sides of the horizontal plate 12, and the top surfaces of the rollers 4 protrude from the upper and lower surfaces of the horizontal plate 12. Figure 6 As shown, when the clamp is disassembled, the rollers 4 on the upper and lower sides of the horizontal plate 12 rotate in the direction of the arc arrow in the figure, so that the clamp can be smoothly separated and disassembled from the plate.

[0035] Preferably, Figure 4 As shown, the rollers 4 arranged on the upper and lower sides of the horizontal plate 12 are staggered in the horizontal direction. This arrangement can reduce the thickness of the horizontal plate 12. After the thickness is reduced, it is convenient for the horizontal plate 12 to be inserted into the bottom side of the thinner plate for lifting operations.

[0036] To achieve the up and down movement of the roller 4 on the upper surface of the horizontal plate 12, as shown in FIG. Figure 8-10 As shown, a groove 1a is provided on the upper surface of the horizontal plate 12 for embedding the rotating shaft 41 of the roller 4 and adjusting the height of the rotating shaft, and an adjusting screw 5 is provided on the side wall of the horizontal plate 12 for driving the rotating shaft to move up and down. Fig.10As shown, when hoisting the plate, the adjusting screw 5 is rotated to drive the roller 4 to move downward and retract its top side below the upper surface of the horizontal plate 12. When hoisting the plate, the plate can be in flat contact with the upper surface of the horizontal plate 12 to ensure the contact friction and hoisting stability during the hoisting process; and when disassembling the clamp, as shown in FIG. Fig. 9 As shown, the roller 4 is driven upward by adjusting the screw rod 5 and extended to the upper surface of the horizontal plate 12, so that the plate is separated from the upper surface of the horizontal plate 12, and the rolling disassembly operation can be realized.

[0037] The principle of the present application is: when the clamp of the present application is used to lift and transport the plate, first, by rotating the adjusting screw 5, the roller 4 is driven to be lower than the upper surface of the horizontal plate 12, and then the horizontal plate 12 is extended to the bottom of the plate, and the lifting rope 3 is lifted up so that the pressure plate is pressed against the surface of the plate, and the lifting operation of the plate can be realized. When the clamp needs to be disassembled, the adjusting screw 5 is driven in the reverse direction and the roller 4 is driven to move upward and extend out of the top surface of the horizontal plate 12, so that the plate is separated from the upper surface of the horizontal plate 12, and the rolling disassembly operation can be realized.

[0038] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
