Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and in particular to a hydraulic cylinder clamp. Background Technology
[0002] In industrial production, hydraulic cylinders are used as core power components in numerous applications. However, currently, manual handling and installation are commonly employed. Multiple operators typically move the cylinders from the storage area to the installation station by hand or using simple levers, before installation. However, this process presents several problems: First, due to the significant weight of the cylinders, prolonged manual handling can lead to exhaustion and safety hazards. Furthermore, the need for repeated adjustments to positioning and force application during manual handling and installation results in low efficiency. Second, uneven force distribution during multiple handling can cause mechanical impacts between the cylinder surface and the lifting equipment or mounting base, resulting in surface scratches or plating damage, affecting product quality.

[0022] This utility model discloses a hydraulic cylinder clamp. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.
[0023] Combination Figure 1 and Figure 2 As shown, a hydraulic cylinder clamp includes a clamping rod 1, a support arm 4, and a clamping assembly. The clamping rod 1 is arranged vertically, with a sleeve fixedly connected to its bottom. The support arm 4 is arranged horizontally, with a rotating shaft 5 fixedly connected to one end. The rotating shaft 5 is adapted to be inserted into the sleeve and is rotatably connected to the sleeve through several bearings. The support arm 4 is perpendicular to the clamping rod 1 and rotates relative to the clamping rod 1 under the action of external force. Two U-shaped first operating handles 2 are fixedly connected to the left and right sides of the upper part of the clamping rod 1. A pneumatic control box 3 is fixedly connected to the lower part of the clamping rod 1, and an indicator light is provided on the top of the pneumatic control box 3 to display the load status. Two U-shaped second operating handles 6 are fixedly connected to the left and right sides of the support arm 4. The first operating handles 2 and the second operating handles 6 are convenient for the operator to grip and adjust the moving position of the hydraulic cylinder clamp.
[0024] Combination Figure 3 and Figure 4 As shown, a slewing bearing 7 is fixed to the bottom of the other end of the support arm 4, and a clamping assembly is provided at the bottom of the slewing bearing 7. The clamping assembly includes a bracket 8, a clamping cylinder 16, and a gripper 11. The top of the bracket 8 is fixedly connected to the bottom of the slewing bearing 7. Hinges 9 are fixedly connected to both the left and right sides of the bottom of the bracket 8. The clamping cylinder 16 is located between the two hinges 9, and the top of the clamping cylinder 16 is fixedly connected to the top of the bracket 8. Auxiliary handles are fixedly connected to both the left and right sides of the bracket 8, and the pneumatic control box 3 is connected to the clamping cylinder 16.
[0025] The gripper 11 is located below the hinge seat 9 and the clamping cylinder 16. The gripper 11 is divided into a left gripper and a right gripper, which are arranged symmetrically about the clamping cylinder 16. Both the left and right grippers include a first connecting plate and a second connecting plate, which have the same structure. The upper part of both the first and second connecting plates has a rectangular segment, and the lower part has an arc-shaped segment. There is a gap between the rectangular segments of the first and second connecting plates, and a first rotating shaft 13 and a second rotating shaft 14 are arranged within the gap. The first rotating shaft 13 and the second rotating shaft 14 are rotatably connected to the first and second connecting plates, respectively. The arc-shaped segments of the first and second connecting plates are fixedly connected by several fixing rods. The first rotating shaft 13 is located inside the second rotating shaft 14 and adjacent to the arc-shaped segments. A buffer pad 12, made of flexible material, is fixedly connected to the inner end face of each arc-shaped segment. A push rod 15 is fixedly connected to the bottom of the clamping cylinder 16. The push rod 15 is located between the first rotating shaft 13 of the left jaw and the first rotating shaft 13 of the right jaw, and is rotatably connected to both the first rotating shaft 13 of the left jaw and the first rotating shaft 13 of the right jaw. The hinge seat 9 located on one side of the bracket 8 is rotatably connected to the second rotating shaft 14 on the left jaw through the connecting rod 10, and the hinge seat 9 located on the other side of the bracket 8 is rotatably connected to the second rotating shaft 14 on the right jaw through the connecting rod 10.
[0026] A controller and a limit switch 17 are provided. The controller is connected to both the limit switch 17 and the clamping cylinder 16. The limit switch 17 is located between the left and right jaws and is fixedly connected to the push rod 15. A lever is rotatably connected to the limit switch 17. The lever extends downward into the space between the left and right jaws and is triggered when the left and right jaws clamp the hydraulic cylinder 18.
[0027] like Figure 5As shown, after assembling the various components, the clamping rod 1 of the hydraulic cylinder clamp is fixedly connected to the lifting host via a flange. The lifting host is used to drive the hydraulic cylinder clamp to achieve rotation and lifting functions. First, the operator moves the gripper 11 above the hydraulic cylinder 18 using the first operating handle 2 and the second operating handle 6. Then, the lifting host drives the hydraulic cylinder clamp to descend and stop at a suitable position, allowing the hydraulic cylinder to enter the space between the left and right grippers. During the descent of the gripper 11, the hydraulic cylinder 18 contacts the lever of the limit switch 17, and as the gripper 11 descends, the lever gradually rotates to open the limit switch 17. At this time, the operator can activate the clamping cylinder 16, which causes the piston rod to retract and, in conjunction with the connecting rod 10, drives the left and right grippers to move towards each other, clamping the hydraulic cylinder 18. At this point, the gripper 11 changes from an unloaded state to a loaded state. However, if the limit switch 17 is not open, the gripper 11 remains in a controlled state, preventing the operator from activating the clamping cylinder 16. This avoids the possibility of the gripper 11 directly switching to a load state and causing injury or damage to other surrounding equipment due to operator error, thus improving the safety of the gripper 11. The arc-shaped sections on the left and right grippers are adapted to the outer contour of the hydraulic cylinder 18, and the buffer pads 12 fixed to the inner end faces of the arc-shaped sections can cushion the hydraulic cylinder 18, preventing damage to the outer surface of the hydraulic cylinder 18 during the clamping process of the left and right grippers. After the left and right grippers have stabilized the hydraulic cylinder 18, the lifting host gradually raises the hydraulic cylinder clamp to a suitable position and then stops. The operator can adjust the rotation of the hydraulic cylinder 18 in the lateral direction by holding the auxiliary handles located on both sides of the bracket 8 and using the slewing bearing 7; and can also adjust the rotation of the hydraulic cylinder 18 in the vertical direction by holding the second operating handles 6 located on both sides of the support arm 4 and using the rotating shaft 5. Workers can flexibly adjust the position and angle of the hydraulic cylinder 18 by rotating it in the horizontal and vertical directions, which facilitates the installation of the hydraulic cylinder 18.
[0028] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
