Description

Wire rope clamping device

The new model relates to a hand-held tool, in particular to a wire rope clamping device.

When the operator is hoisting the rolls in the factory area, the rolls must be connected to the crane through steel cables for hoisting due to the heavy weight of the rolls. When fixing the wire rope hanging downward from the overhead crane to the roll to be hoisted, considering the safety factor, the operator will hold an existing auxiliary tool 1 as shown in FIG. 1 to work. The auxiliary tool 1 includes a handle 11 , an extension rod 12 extending from the handle 11 , and an end connected to the extension rod 12 away from the handle 11 , and defining an opening 131 around it and suitable for The hook 13 for accommodating the hooking space 130 of the wire rope. The operator can hold the handle 11 of the auxiliary tool 1 and keep a safe distance from the wire rope by the length of the extension rod 12 . Then, using the hook 13, the purpose of adjusting the position where the wire rope is hooked on the roll can be achieved by allowing the wire rope to enter the hooking space 130 through the opening 131.

However, in order for the wire rope to enter the hooking space 130 through the opening 131 smoothly, the opening 131 is generally opened laterally in a direction perpendicular to the extension rod 12 and is adjacent to the extension rod 12 . Although this design makes it easier for the wire rope to enter the hooking space 130 , and it is easy to move the wire rope in the pulling direction through the hook 13 . However, when it needs to be operated in the pushing direction, the positional relationship of the opening 131 will cause the disadvantage that the wire rope is relatively easy to escape from the hooking space 130 from the opening 131 . At this time, in order to adjust the demand, the operator needs to directly hold the wire rope to adjust, which goes against the original intention of allowing the operator to use the auxiliary tool 1 to maintain work safety, and cannot truly meet the operation demand of multi-directional adjustment.

Therefore, the purpose of the present invention is to provide a wire rope clamping device that is convenient for hand-held operation and can ensure that the wire rope is not easily disengaged when moving in multiple directions.

Therefore, the novel wire rope clamping device includes an extension tube that is hollow and defines an inner space extending along an axis, at least one fixing claw fixed to the extension tube and having at least a part of it extending in a direction perpendicular to the axis , a movable claw that penetrates the inner space and can move back and forth along the axis, a handle fixed to the extension tube and includes a limit portion along the axis and a distance from the extension tube, and a connection on the operating handle of the movable claw.

The movable claw includes a straight rod segment extending along the axis and passing through the inner space, and a hook segment connected to the front end of the straight rod segment and bent in a direction perpendicular to the axis. The movable claw can move between an initial position in which the hook segment is spaced apart from the at least one fixed claw and a clamping position in which the hook segment moves toward the at least one fixed claw.

Therefore, when the movable claw 4 moves backward relative to the extension tube 2 along the axis L, the block 43 of the movable claw 4 will move toward the end wall 22 , thereby compressing the compression spring 7 to accumulate an elasticity Resilience.

The handle 5 includes a limit portion 51 spaced from the extension tube 2 along the axis L at a distance, and a limit portion 51 connected between the extension tube 2 and the limit portion 51 and connected to the limit portion 51 surrounds a surrounding portion 52 that defines an operating space 500 . Specifically, the handle 5 is generally a rectangular frame surrounding the operating space 500, so as to be convenient for the user to hold.

The operating handle 6 is connected to the straight rod section 41 of the movable claw 4, and is arranged in the operating space 500, so it is located between the limiting portion 51 of the handle 5 and the extension tube 2, which is beneficial to When the user holds the handle 5, the operation handle 6 is clasped with four fingers to operate. The operating handle 6 includes a buckling portion 61 adjacent to the limiting portion 51 of the handle 5 and suitable for pulling operation, and abutting portion 61 that is spaced from the buckling portion 61 along the direction parallel to the axis L at a distance part 62 , and two connecting parts 63 respectively connected between the buckling part 61 and the opposite ends of the abutting part 62 .

Referring to FIG. 5 in conjunction with FIG. 4 , when using this embodiment to hold a hanging wire 9 , the user only needs to hold the handle 5 and pull the operating handle 6 , so that the movable claw 4 can be freed from one of the hook segments The initial position where the 42 is spaced apart from the fixing claws 3 is moved to a clamping position where the hook segment 42 moves toward the fixing claws 3 . When the movable claw 4 is in the initial position, the abutting portion 62 of the operating handle 6 is used for abutting against the extension tube 2, thereby preventing the movable claw 4 from continuing to move forward relative to the extension tube 2, The movable claw 4 is maintained at the initial position. When the movable claw 4 moves to the clamping position, since the curved hook segment 42 of the movable claw 4 and the fixed hook segments 32 of the fixed claws 3 are spaced back and forth along the axis L direction, when using this In the embodiment, the hanging wire 9 is clamped. No matter the user moves forward or backward to adjust the hanging position, the hanging wire 9 is not easily disengaged.

It is worth noting that when the movable claw 4 is in the clamping position, the stopper 43 moves toward the end wall 22 to compress the compression spring 7 , so the adjustment operation of clamping the hanging wire 9 is completed. Afterwards, as long as the user does not hold the operating handle 6 to release the elastic restoring force accumulated by the compression spring 7 freely, the elastic restoring force can reversely move the movable claw 4 forward until the operating handle 6 The abutting portion 62 is abutted against the extension tube 2 again, that is, it is automatically reset to the initial position to prepare for the next clamping adjustment operation, thereby optimizing the convenience of use and improving the operation efficiency.

To sum up, in this embodiment of the novel wire rope clamping device, the user can easily move the movable claw 4 as long as the user holds the handle 5 and pulls the operating handle 6 relative to the handle 5 with his fingers To the clamping position, the wire rope is clamped, and during the adjustment operation, no matter how to move back and forth along the direction parallel to the axis L, the wire rope is not easy to fall off the specific opening, so it can move freely in more directions. Helps in the work of slinging a wire rope to a specific item. Therefore, the purpose of this new model can indeed be achieved.
