[0026] The embodiments of the present application solve the problems in the prior art by providing a cylindrical clamp for a forklift.
[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:
[0028] The specific structure of this embodiment is as follows: Figures 1 to 6 As shown, a cylindrical clamp for forklift includes a mounting frame 1, mounting rods 2 are fixedly connected to the tops of both ends of the mounting frame 1, a mounting ring 3 is fixedly connected between the two groups of mounting rods 2, a clamping assembly 4 is arranged inside the mounting ring 3, a vertical rod 5 is fixedly connected to one side of the middle part of the mounting ring 3, an extension rod 6 is arranged on the top of the vertical rod 5, a clamping plate 7 is fixedly connected to the bottom of the vertical rod 5 and the top of the extension rod 6, and an adjustment assembly 8 is arranged at the connection between the extension rod 6 and the vertical rod 5.
[0029] In some examples, the clamping assembly 4 includes a cavity 41, a swivel 42, an arc plate 43, a through groove 44, a push rod 45 and a push block 46. The cavity 41 is opened inside the mounting ring 3 and is annular. The swivel 42 is rotatably connected to the cavity 41, the arc plate 43 is fixedly connected to the inner side of the swivel 42, the through groove 44 runs through the inner wall of the inner side of the cavity 41, the push rod 45 is slidably connected to the through groove 44 and the end close to the cavity 41 is arc-shaped, and the push block 46 is fixedly connected to the end of the push rod 45 away from the cavity 41. Rotating the swivel 42 can drive the arc plate 43 to move synchronously. When the arc plate 43 moves to the rear of the push rod 45, since the end of the push rod 45 close to the cavity 41 is arc-shaped, the push rod 45 will be pushed out toward the center of the mounting ring 3 by the arc plate 43, thereby driving the push block 46 to move toward the center of the mounting ring 3.
[0030] In some examples, the clamping assembly 4 also includes a first slide groove 47, a first slider 48 and a first spring 49. The first slide groove 47 is opened at the top of the mounting ring 3 and is connected to the cavity 41. The first slider 48 is fixedly connected to the top of the swivel 42 and is slidably connected to the first slide groove 47. The first spring 49 is fixedly installed inside the first slide groove 47 and its two ends are respectively fixedly connected to one side of the first slider 48 and the inner wall of one side of the first slide groove 47. The first slider 48 is slid along the first slide groove 47 to squeeze the first spring 49 and drive the swivel 42 to rotate along the cavity 41. The first slider 48 is released, and the first spring 49 rebounds to drive the swivel 42 to reset through the first slider 48.
[0031] In some examples, the clamping assembly 4 also includes a second slide groove 410, a second slider 411 and a second spring 412. The second slide groove 410 is opened on the inner wall of the bottom of the cavity 41 and is below the push rod 45. The second slider 411 is fixedly connected to the bottom of the push rod 45 and is slidably connected to the second slide groove 410. The second spring 412 is fixedly installed inside the second slide groove 410 and its two ends are respectively fixedly connected to one side of the second slider 411 and the inner wall of one side of the second slide groove 410. The sum of the elastic force of the second spring 412 is less than the elastic force of the first spring 49. When the arc plate 43 pushes the push rod 45 toward the center of the mounting ring 3, it will drive the second slider 411 to slide synchronously along the second slide groove 410 and squeeze the second spring 412. When the arc plate 43 moves away from the rear of the push rod 45, the second spring 412 rebounds and can drive the push rod 45 to move toward the inside of the cavity 41 through the second slider 411.
[0032] In some examples, the adjustment component 8 includes an adjustment slot 81, a fixing hole 82, a through hole 83 and a fixing rod 84. The adjustment slot 81 is opened at the top of the vertical rod 5, and the extension rod 6 is slidably connected to the adjustment slot 81. The fixing rod 84 is provided with several groups and passes through the extension rod 6. The through hole 83 passes through the inner wall of one side of the adjustment slot 81. The fixing rod 84 is movably connected to the through hole 83 and is adapted to the size of the fixing hole 82. The height of the extension rod 6 can be adjusted by moving the fixing rod 84 out of the fixing hole 82, and the extension rod 6 can be fixed at the current position by inserting the fixing rod 84 into the fixing hole 82.
[0033] In some examples, the adjustment component 8 also includes a third slide groove 85, a third slider 86, a third spring 87 and a pull block 88. The third slide groove 85 is opened on the inner wall of the through hole 83, the third slider 86 is fixedly connected to the outer periphery of the fixed rod 84 and is slidably connected to the third slide groove 85, the third spring 87 is sleeved on the outer periphery of the fixed rod 84 and its two ends are respectively fixedly connected to one side of the third slider 86 and the inner wall of one side of the third slide groove 85, the pull block 88 is fixedly connected to the outer end of the fixed rod 84, and pulling the pull block 88 outward can drive the fixed rod 84 to move outward along the through hole 83 and squeeze the third spring 87 through the third slider 86. Release the pull block 88, the third spring 87 rebounds and drives the fixed rod 84 to move inward through the third slider 86.
[0034] In a specific application scenario, first slide the first slider 48 along the first slide groove 47 to squeeze the first spring 49 and drive the swivel 42 to rotate along the cavity 41. During this process, the arc plate 43 moves synchronously with the swivel 42 and moves away from the rear of the push rod 45. At this time, the second spring 412 rebounds and drives the push rod 45 to move toward the inside of the cavity 41 through the second slider 411. When the top block 46 moves synchronously with the push rod 45 to fit closely with the inner wall of the mounting ring 3, the mounting ring 3 is placed on the outside of the cylinder to be clamped and the clamping plate 7 at the bottom of the vertical rod 5 is placed at the bottom of the cylinder. Then, the first slider 48 is released, the first spring 49 rebounds and drives the swivel 42 to reset through the first slider 48. During this process, the arc plate 43 moves synchronously with the swivel 42 to the rear of the push rod 45. Since the end of the push rod 45 close to the cavity 41 is arc-shaped and the elastic force of the first spring 49 is greater than the elastic force of the second spring 412 The sum of the forces, therefore, the push rod 45 will be pushed out toward the center of the mounting ring 3 by the arc plate 43 and squeeze the second spring 412 through the second slider 411. When the push block 46 is tightly fitted with the surface of the cylinder, it can be fixed in the mounting ring 3 by the resilience of the first spring 49, and then the pull block 88 is pulled outward to drive the fixing rod 84 to move outward and squeeze the third spring 87 through the third slider 86. When the fixing rod 84 moves out of the fixing hole 82, the extension rod 6 is slid along the adjustment groove 81 until the clamping plate 7 at its top is tightly fitted with the top of the cylinder, and then the pull block 88 is released, the third spring 87 rebounds and drives the fixing rod 84 to move inward through the third slider 86. When the fixing rod 84 is inserted into the fixing hole 82 at the current position, the extension rod 6 can be fixed at the current height, thereby further clamping the cylinder, and then the forklift is started to insert the fork into the mounting frame 1 to move the cylinder.
[0035] By adopting the above technical solution, not only can the clamp be used to clamp and fix cylinders of different diameters and heights, but the entire operation process is also simpler and faster, effectively improving work efficiency.
[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
