Description

Technical Field

[0001] The utility model relates to a clamp, in particular to an aluminum ingot clamp. Background Art

[0002] Existing aluminum ingot clamps often utilize a single set of jaws to clamp aluminum ingots. Since aluminum ingot clamps are often transported to the ingot's location using a hoisting device, in order for the jaws to effectively grip the ingot and minimize any deflection or shaking during transportation, the single set of jaws must be able to contact the center of the ingot as closely as possible. This requires the operator to lower the clamp with greater precision, leading to high requirements for clamping operations. Furthermore, the reliability of clamping aluminum ingots with a single set of jaws is limited. If the jaws fail, the ingot is likely to fall, posing a safety hazard. Utility Model Content

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] The utility model discloses an aluminum ingot clamp, the overall structure of which is as follows Figure 1 As shown, it mainly includes an aluminum ingot clamp 2, a clamping cylinder for driving the aluminum ingot clamp 2 to clamp, a lifting base plate 1 for installing the aluminum ingot clamp 2, a lifting cylinder 5 for driving the lifting base plate 1 to move up and down, and a guide slide 9 for guiding support.

[0022] First, relying on the lifting base plate 1, two groups of aluminum ingot clamps 2 are symmetrically distributed in the front and back. One group of aluminum ingot clamps 2 is equipped with a clamping cylinder 11. The same solenoid valve can be used to control and adjust the pressure of the two cylinders to reach the same speed, so that the clamping cylinders of the two groups of aluminum ingot clamps 2 run synchronously, thereby achieving the purpose of the two groups of aluminum ingot clamps 2 jointly clamping and transporting aluminum ingots.

[0023] As for the clamping cylinder 11, it is assembled in the mounting hole of the lifting base plate 1 through the fixing flange 12, and the aluminum ingot clamping claw 2 is located below the lifting base plate 1. The specific structure is as follows Figure 2 As shown, the aluminum ingot clamp 2 includes a base-type fixed arm 21, a main body clamping arm 22, a central shaft 25 and a transmission arm 26;

[0024] The base portion of the base-type fixed arm 21 is fixedly connected to the bottom of the lifting base plate 1, and the arm portion of the base-type fixed arm 21 is hingedly connected to the main body clamping arm 22, which is used to clamp the aluminum ingot;

[0025] In order to realize the action driving of the clamping cylinder 11 on the main body clamping arm 22, the output end of the clamping cylinder 11 passes downward through the base part of the base-type fixed arm 21 and is fixedly connected to the central axis 25. The transmission arm 26 that realizes the transmission function is hingedly connected between the main body clamping arm 22 and the central axis 25 to realize the action driving of the clamping cylinder 11 on the main body clamping arm 21.

[0026] Therefore, when the clamping cylinder 11 pushes the transmission arm 26 outward, the transmission arm 26 opens the main clamping arms 22 on both sides, so that the aluminum ingot clamping claw 2 is in an open state; and when the clamping cylinder 11 pulls back the transmission arm 26, the transmission arm 26 tightens the main clamping arms 22 on both sides, so that the aluminum ingot clamping claw 2 is in a clamping state.

[0027] The main clamping arm 22 specifically clamps the aluminum ingot through a clamping plate 23 fixedly connected to the bottom end of the arm body of the main clamping arm 22. A protective pad 24 is laid on the clamping plate 23, and a positioning column 27 is provided to adapt to the side holes of the packaged aluminum ingot. The positioning column 27 can increase the reliability of the clamping plate 23 in clamping the aluminum ingot.

[0028] The aluminum ingot clamp 2 has a simple structural implementation, which makes the entire aluminum ingot clamp compact. Therefore, even when a double set of aluminum ingot clamps is provided, the entire aluminum ingot clamp will not be too bulky. To further optimize the performance of the entire aluminum ingot clamp, the lifting base 1 has the function of driving the entire aluminum ingot clamp 2 up and down. When the aluminum ingot clamp is lowered to hold the aluminum ingot, if the height position of the aluminum ingot clamp needs to be further adjusted up and down, the relevant structural setting can meet the requirements of the up and down adjustment operation of the aluminum ingot clamp.

[0029] The lifting base plate 1 is specifically designed to lift up and down: Figure 1 As shown, the lifting cylinder 5 provides the driving force for the up and down movement of the lifting base plate 1. The lifting cylinder 5 is fixedly mounted below the lifting eye fixing frame 6. The lifting eye fixing frame 6 is also used to set the lifting eye 7. That is, the lifting eye 7 is fixedly mounted above the lifting eye fixing frame 6, and the lifting eye 7 is used to cooperate with the hook of the lifting device.

[0030] As for the lifting ear fixing frame 6, it is welded and fixed to the top of the portal frame. The portal frame consists of two vertically distributed columns 3 and fixed plates 8 welded and fixed to the front and rear sides of the top ends of the two columns 3; the lifting ear fixing frame 6 spans the fixed plate 8 at the front and rear and is welded and fixed at the middle position of the fixed plate 8. When the lifting ear 7 located in the middle position is used in conjunction with the hook of the lifting device, the entire device can be kept in a balanced state.

[0031] Therefore, the lifting ear fixing frame not only meets the lifting ear setting requirements, but is also used for the installation of the lifting cylinder 5. Moreover, the fixing plates 8 are distributed in the front and rear directions of the column, and the lifting cylinder 5 is synchronously located in the space clamped by the front and rear fixing plates, thereby making the space utilization of the entire aluminum ingot clamp more reasonable and not excessively increasing the overall height of the aluminum ingot clamp.

[0032] While providing support, the column 3 also provides guiding assistance for the driving action of the lifting cylinder 5. The output end of the lifting cylinder 5 is connected to the guide plate 4, and sliders 10 are fixed on both sides of the guide plate 4. A guide groove 9 adapted to the slider 10 is formed on the column 3. The guide groove 9 cooperates with the slider 10 to achieve guided sliding, and the guide plate 4 and the lifting base plate 1 are fixedly connected by the connecting rod 13, so that the lifting cylinder 5 can drive the lifting base plate 1 to move up and down.

[0033] Therefore, for the aluminum ingot clamp disclosed in the utility model, a double set of aluminum ingot clamps are integrated to jointly clamp and transport the aluminum ingots. The double set of aluminum ingot clamps improves the clamping effect on the one hand, and provides more clamping sites on the other hand, making the operation of lifting, lowering and balancing the aluminum ingot clamp to be simpler, thereby improving the lifting and transportation efficiency of the aluminum ingots to a certain extent.

[0034] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
