[0002] In the maintenance of elevators, it is necessary to trim the traction wire rope of the elevator or to hoist the elevator car. After the rope is removed, the wire rope is very easy to relax unevenly, causing staggering and overlapping. A clamping device is needed to fix the wire rope. The combined rope clamp is one of the clamping devices.

[0003] Traditional combination rope clamps generally clamp wire ropes through two rope clamping grooves that match each other. Since the shape of the rope clamping grooves is fixed, the thickness range of the wire ropes that can be clamped by a combination rope clamp is small, resulting in the need for workers to use multiple combination clamps suitable for wire ropes of different thicknesses when performing maintenance work, which reduces work efficiency. In addition, when the cross-sectional size of the wire rope is similar to the cross-sectional size of the matching rope clamping groove, the pressure on the wire rope is limited, and the combination clamp has a poor fixing effect on the wire rope.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example:

[0026] like Figures 1 to 6 As shown, this embodiment provides a portable combined rope clamp for elevator maintenance, including a rope clamp seat 1 and a rope clamp plate 2. The rope clamp seat 1 is a rectangular parallelepiped with square shapes at both ends. Rope clamp grooves A3 are evenly arranged on the outer walls of the rope clamp seat 1 in the four directions of up, down, front and back. The sizes of the rope clamp grooves A3 on the same surface are similar, and the sizes of the rope clamp grooves A3 on different surfaces are different. The four outer walls of the rope clamp seat 1 with rope clamp grooves A3 each have a matched rope clamp plate 2. The rope clamp plate 2 is provided with a rope clamp groove B4 corresponding to the rope clamp groove A3. The surface of the rope clamp plate 2 away from the rope clamp groove B4 is provided with a tightening group The tightening assembly 5 can adjust the extension length of its tensioning component in the rope clamping groove B4. When the outer wall of the rope clamping seat 1 with the rope clamping groove A3 is matched with the rope clamping plate 2 matched therewith, the rope clamping groove A3 is matched with the rope clamping groove B4, and the steel wire rope of the elevator is clamped by the rope clamping groove A3 and the rope clamping groove B4. The tensioning component of the tightening assembly 5 is against the steel wire rope. The rope clamping seat 1 is symmetrically provided with threaded through holes A6 on the left and right sides, and the rope clamping plate 2 is provided with threaded through holes B7 corresponding to the threaded through holes A6. The rope clamping seat 1 and the rope clamping plate 2 are fastened by screwing fixing bolts 8 into the overlapping threaded through holes A6 and B7.

[0027] The outer walls of the rope clamping seat 1 in four directions are respectively provided with rope clamping grooves A3 of different sizes, which cooperate with the rope clamping grooves B4 on the corresponding rope clamping plate 2 to meet the clamping needs of steel wire ropes of different thicknesses, have a wide range of applications, and are convenient for maintenance operations. The rope clamping plate 2 is provided with a tightening component 5, which uses an elastic component that can adjust the length of the rope clamping groove B4 to further squeeze the steel wire rope through the extended elastic component, so as to better fix the steel wire rope clamped by the rope clamping grooves A3 and B4, thereby improving the fixing effect.

[0028] Furthermore, the tightening assembly 5 includes a movable plate 9, an insert rod 10 and a pressure head 11. The movable plate 9 is provided on the side of the rope clamping plate 2 away from the rope clamping groove B4. The movable plate 9 is rotatably connected with a rotating head 12. The upper and lower ends of the rotating head 12 are respectively located on the upper and lower sides of the movable plate 9. The upper end of the rotating head 12 is coaxially connected with a turning handle 13, and the lower end of the rotating head 12 is coaxially connected with a threaded rod 14. The rope clamping plate 2 is provided with a threaded groove 15 threadedly connected to the threaded rod 14. The threaded groove 15 is along the vertical direction, and the inner edge of the rope clamping plate 2 is Each rope clamping groove B4 is evenly provided with a sliding cavity 16, and the sliding cavity 16 is along the vertical direction. A pressure head 11 is slidably connected in the sliding cavity 16. A through hole A17 pointing to the movable plate 9 is provided at the top of the sliding cavity 16, and an insertion rod 10 corresponding to the through hole A17 is provided at the bottom of the movable plate 9. The insertion rod 10 is inserted into the sliding cavity 16 through the through hole A17 and can abut against the upper end of the pressure head 11. A through hole B18 leading to the rope clamping groove B4 is provided at the bottom of the sliding cavity 16. The lower end of the pressure head 11 penetrates into the rope clamping groove B4 from the through hole B18 and abuts against the wire rope.

[0029] By using the sliding cavity 16 and the insertion rod 10 in combination, the movable plate 9 is restricted to move in the vertical direction. When the user holds the turning handle 13 and turns it, the threaded rod 14 indirectly connected to the turning handle 13 via the rotating head 12 will be driven to rotate. When the threaded rod 14 moves in the vertical direction along the threaded groove 15, the movable plate 9 indirectly connected to the threaded rod 14 via the rotating head 12 can be driven to move in the vertical direction, thereby changing the height of the insertion rod 10 connected to the movable plate 9. The descending insertion rod 10 presses down the pressure head 11, and the pressure head 11 presses the wire rope below the opening B18. The longer the length of the insertion rod 10 extending into the sliding cavity 16 is, the longer the length of the part of the pressure head 11 pressed out of the sliding cavity 16 is, and the better the fixing effect of the wire rope is. Specifically, when the lower end of the insertion rod 10 is flush with the opening A17 and the lower end of the pressure head 11 is flush with the opening B18, a certain distance should be left between the lower end of the insertion rod 10 and the upper end of the pressure head 11 to facilitate the combination of the rope clamping seat 1 and the rope clamping plate 2 and the rope clamping groove B4 to press the wire rope placed in the rope clamping groove A3. The lower end of the pressure head 11 can be pushed back into the sliding cavity 16 so that the pressure head 11 does not hinder the combination operation between the rope clamping seat 1 and the rope clamping plate 2.

[0030] Furthermore, an insertion rod 10 for inserting into the sliding cavity 16 corresponding to the two rope clamping grooves B4 is provided at the bottom of a movable plate 9 , and the insertion rod 10 is evenly distributed on the left and right sides of the bottom of the movable plate 9 .

[0031] Furthermore, the number of sliding cavities 16 corresponding to one rope clamping groove B4 is three.

[0032] Furthermore, the rope clamping groove A3 and the rope clamping groove B4 are uniformly provided with anti-skid grooves 19 along the length direction. The anti-skid grooves 19 improve the fixing effect of the rope clamping groove A3 and the rope clamping groove B4 on the wire rope.

[0033] Furthermore, the threaded through holes A6 on the same side of the rope clamping seat 1 are in a cross shape, and the intersections of the threaded through holes A6 are connected to each other.

[0034] Furthermore, the number of the rope clamping grooves B4 on the rope clamping plate 2 is eight.

[0035] The working principle and use process of this utility model:

[0036] The staff selects a suitable rope clamping plate 2 according to the thickness of the wire rope, places the rope clamping seat 1 with the corresponding matching surface of the rope clamping plate 2 facing upward, and puts the wire rope into the rope clamping groove A3 of the rope clamping seat 1 facing upward in a one-to-one manner. After placing the wire rope, first turn the turning handle 13 to raise the lower end of the insertion rod 10 to the opening A17, and then close the rope clamping plate 2 on the rope clamping seat 1 in a manner that the rope clamping groove B4 is aligned with the rope clamping groove A3, and then screw the fixing bolts 8 into the overlapping threaded through holes A6 and threaded through holes B7, tighten the rope clamping seat 1 and the rope clamping plate 2, and the matched rope clamping grooves A3 and rope clamping grooves B4 clamp the wire rope. Finally, turn the turning handle 13 to lower the insertion rod 10, and the insertion rod 10 presses down the pressure head 11, and the pressure head 11 further presses the wire rope to complete the fixing of the wire rope.

[0037] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
