Description

Technical Field

[0001] This utility model relates to the technical field of aluminum ingot production, specifically to an adjustable hydraulic clamp. Background Technology

[0002] Aluminum ingots are lumpy blocks of aluminum metal obtained through smelting and purification. They are silvery-white and possess characteristics such as light weight, good thermal conductivity, and corrosion resistance. With the rapid development of the aluminum industry, casting small aluminum ingots can no longer meet production demands. This is because small ingots not only consume more primary aluminum than large ingots, but also require packaging during transportation, increasing production costs. Therefore, large aluminum ingot casting production lines are imperative. In industrial production, large aluminum ingots need to be formed into flat plates. For example, the length of 3104 aluminum alloy large flat ingot blanks ranges from 4100mm to 7100mm, and the width ranges from 900mm to 2100mm. Due to the large weight of aluminum ingots, hoisting is required to transport them to their designated locations. Traditional hoisting methods involve attaching ropes to the aluminum ingots, which is relatively cumbersome, lacks stability during hoisting, and poses safety hazards. Summary of the Invention

[0003] To address the problems of traditional hoisting methods that involve using ropes to lift aluminum ingots, which are relatively cumbersome, lack stability, and pose safety hazards, this invention proposes an adjustable hydraulic clamp to replace the traditional rope hoisting method. This clamp is simple to operate, and after clamping, it improves hoisting stability and reduces safety hazards.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: An adjustable hydraulic clamp includes a frame with an adjustment mechanism. The adjustment mechanism includes a first support plate and a second support plate that moves relative to the first support plate. U-shaped plates are respectively provided at the bottom of the first and second support plates, and each U-shaped plate is equipped with a clamping mechanism. The clamping mechanism includes a connecting rod and a first hydraulic cylinder. One end of the connecting rod is hinged to one end of the telescopic rod of the first hydraulic cylinder, and the other end of the connecting rod is hinged to the U-shaped plate. One end of the cylinder body of the first hydraulic cylinder is hinged to the U-shaped plate, and a clamping block is provided at the bottom of the connecting rod. By designing the clamping mechanism and utilizing the cooperation of the connecting rod and the first hydraulic cylinder, stable clamping of aluminum ingots is achieved. The main function of the adjustment mechanism is to achieve adaptive adjustment for aluminum ingots of different specifications.

[0005] Furthermore, the adjustment mechanism also includes a bracket and a second hydraulic cylinder. The second hydraulic cylinder is disposed on the top of the bracket, and the first and second support plates are slidably disposed on the bottom of the bracket. A first rack is disposed on the first support plate, and a second rack is disposed on the second support plate. A gear is rotatably disposed on the bottom of the bracket, and the gear meshes with the first and second racks respectively. The first rack drives the gear to rotate, and the gear drives the second rack to move in the opposite direction.

[0006] Furthermore, the bracket is provided with an elongated hole, and a connecting plate is provided on the first support plate. The connecting plate is an inverted T-shaped plate and includes a horizontal part and a vertical part. The horizontal part of the connecting plate is fixedly connected to the first support plate, and the vertical part of the connecting plate passes through the elongated hole and is fixedly connected to the telescopic rod of the second hydraulic cylinder. By controlling the extension and retraction of the second hydraulic cylinder, the distance between the first support plate and the second support plate can be easily adjusted.

[0007] Furthermore, the bracket is equipped with a guide rail, and both support plate one and support plate two are equipped with sliders that cooperate with the guide rail. The cooperation between the guide rail and the slider further improves the smoothness of the movement of support plate one and support plate two.

[0008] Furthermore, the clamping block is provided with an anti-slip steel pad, and the inner side of the anti-slip steel pad is provided with raised patterns.

[0009] Furthermore, a lifting ring is provided above the frame. The entire clamp and aluminum ingot are lifted together to the designated position using the lifting ring above the frame.

[0010] The beneficial effects of this utility model through the above technical solution are as follows: The adjustable hydraulic clamp provided by this utility model achieves stable clamping of aluminum ingots through the design of a clamping mechanism and the cooperation of a connecting rod and a hydraulic cylinder. Compared with the traditional rope hoisting method, this clamp can significantly improve the stability of hoisting, thereby reducing safety hazards. At the same time, by setting an adjustment mechanism, the distance between support plate one and support plate two can be flexibly adjusted to accommodate aluminum ingots of different specifications and sizes. This design enhances the versatility and adaptability of the clamp, allowing the same set of clamps to be used for hoisting aluminum ingots of different specifications, thus improving the utilization rate of the equipment.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, this embodiment provides an adjustable hydraulic clamp, including a frame 1. An adjustment mechanism is provided on the frame 1. The adjustment mechanism includes a support plate 1 and a support plate 2 that moves relative to the support plate 1. A U-shaped plate 4 is provided at the bottom of the support plate 1 and the support plate 2. A clamping mechanism is provided on each U-shaped plate 4. The clamping mechanism includes a connecting rod 5 and a hydraulic cylinder 6. One end of the connecting rod 5 is hinged to one end of the telescopic rod of the hydraulic cylinder 6, and the other end of the connecting rod 5 is hinged to the U-shaped plate 4. One end of the cylinder body of the hydraulic cylinder 6 is hinged to the U-shaped plate 4. A clamping block 7 is provided at the bottom of the connecting rod 5.

[0014] The adjustable hydraulic clamp provided by this utility model achieves stable clamping of aluminum ingots through the design of a clamping mechanism and the cooperation of connecting rod 5 and oil cylinder 6. Compared with the traditional rope hoisting method, this clamp can significantly improve the hoisting stability, thereby reducing safety hazards. The main function of the adjustment mechanism is to achieve adaptive adjustment for aluminum ingots of different specifications, ensuring that the hydraulic clamp can maintain good clamping stability under different working conditions.

[0015] In this example, the adjustment mechanism further includes a bracket 8 and a second hydraulic cylinder 9. The second hydraulic cylinder 9 is disposed on the top of the bracket 8. The first support plate 2 and the second support plate 3 are slidably disposed at the bottom of the bracket 8. The first support plate 2 is provided with a rack 10, and the second support plate 3 is provided with a rack 11. A gear 12 is rotatably disposed at the bottom of the bracket 8, and the gear 12 meshes with the first rack 10 and the second rack 11 respectively. The first rack 10 drives the gear 12 to rotate, and the gear 12 drives the second rack 11 to move in the opposite direction.

[0016] Please refer to this again. Figure 3The bracket 8 is also provided with an elongated hole 13. A connecting plate 14 is provided on the support plate 2. The connecting plate 14 is an inverted T-shaped plate and includes a horizontal part and a vertical part. The horizontal part of the connecting plate 14 is fixedly connected to the support plate 2, and the vertical part of the connecting plate 14 passes through the elongated hole 13 and is fixedly connected to the telescopic rod of the hydraulic cylinder 9. By extending and retracting the hydraulic cylinder 9, the inverted T-shaped connecting plate 14 is pushed, the support plate 2 slides, the rack 10 drives the gear 12 to rotate, and the gear 12 drives the rack 11 to move in the opposite direction. The support plate 3 moves away from or closer to the rack 3 simultaneously, which can easily adjust the distance between the support plate 2 and the support plate 3 to match aluminum ingots of different specifications.

[0017] In this example, the bracket 8 is equipped with a guide rail 15, and both the first support plate 2 and the second support plate 3 are equipped with sliders 16 that cooperate with the guide rail 15. The cooperation between the guide rail 15 and the sliders 16 further improves the smoothness of the movement of the first support plate 2 and the second support plate 3, ensuring the stability and reliability of the clamp during clamping operations.

[0018] It is worth mentioning that the clamping block 7 is provided with an anti-slip steel pad 17, and the inner side of the anti-slip steel pad 17 is provided with raised patterns. The anti-slip steel pad 17 and the raised patterns enhance the clamping force of the clamping block 7 on the aluminum ingot, effectively preventing the aluminum ingot from falling off during hoisting.

[0019] In addition, a lifting ring 18 is provided above the frame 1. The lifting ring 18 provided above the frame 1 facilitates the movement of the entire clamp.

[0020] The working principle of this utility model is as follows: When using this adjustable hydraulic clamp to lift aluminum ingots, firstly, according to the specifications and dimensions of the aluminum ingot, operate the hydraulic cylinder 29 to cause its extension rod to drive the connecting plate 14 and the support plate 2 to slide on the bracket 8. Since the support plate 2 is equipped with a rack 10 and the support plate 3 is equipped with a rack 11, and both are engaged with the gear 12 at the bottom of the bracket 8, the extension and retraction of the hydraulic cylinder 29 pushes the inverted T-shaped connecting plate 14, the support plate 2 slides, the rack 10 drives the gear 12 to rotate, the gear 12 drives the rack 11 to move in the opposite direction, and the support plate 3 moves away or closer synchronously. Therefore, the support plate 2 and the support plate 3 will move synchronously and smoothly, thereby adjusting the distance between them to accommodate aluminum ingots of different widths.

[0021] After adjusting the distance between support plate 12 and support plate 23, start the hydraulic cylinder 6 in the clamping mechanism, so that its telescopic rod pushes the connecting rod 5 to rotate around the hinge point on the U-shaped plate 4. The rotation of the connecting rod 5 will drive the clamping block 7 at its bottom to move closer to the aluminum ingot until the anti-slip steel pad 17 on the clamping block 7 is in close contact with the surface of the aluminum ingot. The raised pattern on the inner side of the anti-slip steel pad 17 can increase the friction and prevent the aluminum ingot from falling off during the hoisting process. After clamping the aluminum ingot, the entire clamp and the aluminum ingot are hoisted to the designated position together by the lifting ring 18 above the frame 1.

[0022] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
