Compared with traditional inclined shaft man-car and other methods, it can greatly shorten the time of personnel going up and down the well and reduce physical exertion. However, during the use of downhole elevator, there are operations such as extension of traction rope, adjustment of traction rope stress state and replacement of traction rope, which are restricted by space and environment. Therefore, during the operation, two ordinary steel plates are usually used to clamp the traction rope, and the two steel plates are locked by passing through fastening bolts in the narrow gap between the steel wires to lock the traction rope, and then the slack state of the other side of the traction rope is adjusted to achieve the operation of adjusting the rope or replacing the rope head.

[0003] However, this method has the following disadvantages: (1) the traction rope is clamped by steel plates, the contact area between the steel plate and the traction rope is small, the friction is not enough, and the traction rope is prone to slipping; (2) the traction rope is clamped, and the force is large, and part of the traction rope is unevenly stressed, which can cause individual traction rope to slip; (3) the steel plate used for clamping will deform after being used for several times, which can cause uneven stress and affect the safety of the locked rope; (4) the number of fastening bolts is large, which is inconvenient to use, and because the distance between the ropes is small, the fastening bolts can only be small bolts, and the fastening force of the bolts is small, which can cause the bolts to break if they are tightened too much.

The connecting bolts are inserted into the clamping block holes of the corresponding clamping blocks and the connecting bolt holes of the clamping seat, connecting the left clamping plate and the right clamping plate into one. The distance between the clamping blocks on the clamping seat can be adjusted to adapt to the rope distance between the hoisting steel wires. The clamping blocks can be disassembled and replaced according to the diameter of the hoisting steel wire.

[0005] The patent document with the Chinese patent application number CN201810974050.8 and the publication date of December 11, 2018 discloses a kind of steel wire rope buckle structures of automobile glass lifter, including the steel wire rope being set on guide rail, the quantity of steel wire rope is two, and middle part is cross set, steel wire rope is set with buckle at intersection point, the buckle includes clamping clamp and limiting fixed strip, the quantity of clamping clamp is two, two clamping clamp is connected by limiting fixed strip.It is clamped on a steel wire rope by clamping clamp, and another steel wire rope is passed through limiting fixed strip and first steel wire rope between, two steel wire ropes are fixed together.

Therefore, the scope of the utility model is only limited by the attached claims.

[0032] Example 1

[0033] As Figure 2 And Figure 3As shown, a pressure-equalizing combined rope clamp device includes multiple sets of plate-shaped rope clamps 31 arranged side by side, in pairs. Each plate-shaped rope clamp 31 has a through hole 32 at a corresponding position, and a semi-circular rope groove 33 extending vertically is formed at a corresponding position on the contact surface of each set of plate-shaped rope clamps 31. When the rope clamp device clamps the traction rope, the traction rope is placed in the semi-circular rope groove 33 of each set of plate-shaped rope clamps 31, and all plate-shaped rope clamps 31 are locked together by bolts passing through the through holes of each plate-shaped rope clamp 31. The plate-shaped rope clamps 31 at both ends are the main force-bearing plates, bearing both the pressure and bending stress after the bolts are tightened, as well as the static friction force after the traction rope is clamped. The plate-shaped rope clamps 31 in the middle mainly bear the pressure after the traction rope is clamped and the static friction force between them.

[0034] The device consists of multiple sets of plate-shaped rope clamps 31 arranged side-by-side, in pairs. The two semi-circular rope grooves 33 of each set of plate-shaped rope clamps 31 form a complete circular rope groove for clamping the elevator traction rope 2. Each set of plate-shaped rope clamps 31 clamps each traction rope individually, ensuring a sufficiently stable clamping force. This method also allows for easy adjustment of the number of plate-shaped rope clamps 31 and the size of the rope grooves according to the actual number and size of the traction ropes, facilitating practical use on the production site. Furthermore, although multiple plate-shaped rope clamps are used, all clamps 31 can be clamped at once using a single bolt passing through the through-holes 32 of all the plate-shaped rope clamps 31, making it convenient to use.

[0035] In this embodiment, the plate-shaped rope clamp 31 has four through holes 32, evenly distributed on its end face. When adjusting the clamping force of the traction rope using bolts, this four-hole structure ensures uniform surface stress on each clamp, reduces deformation, increases service life, and guarantees clamping effectiveness. The plate-shaped rope clamp 31 has a width of not less than 80mm and a thickness of not less than 20mm. When all plate-shaped rope clamps 31 are locked together, the gap between clamps in the same group is ≥3mm, and high-strength bolts are used.

One end of the elevator traction rope 2 is connected to an elevator car 6, and the other end is connected to an elevator counterweight 7. Furthermore, it includes a fixedly mounted elevator steel platform 4 through which the elevator traction rope 2 passes. The elevator steel platform 4 is equipped with a pressure-equalizing combined rope clamp device 3 as described in Embodiment 1, and the other end of the elevator traction rope 2 passes through the semi-circular rope groove 33 of the pressure-equalizing combined rope clamp device 3.

[0038] Two fixed I-shaped steel 5 are fixedly installed on the elevator steel platform 4, the two fixed I-shaped steel 5 have a gap for the elevator hoisting rope 2 to pass through, and the pressure equalizing combined rope clamp device 3 is supported and arranged on the fixed I-shaped steel 5. Before installation, the fixed I-shaped steel can be removed, and then installed on the elevator steel platform 4 during use, and bolt connection or welding can be used for fixation, so that the whole installation steps are simple, and the on-site installation efficiency can be greatly improved. The upper end face of the fixed I-shaped steel 5 is provided with a limiting sliding groove for placing the pressure equalizing combined rope clamp device 3, when the plate-shaped rope clamp 31 is locked, the limiting sliding groove can limit the displacement of the plate-shaped rope clamp 31 in the width direction, and the clamping degree of the elevator hoisting rope 2 is guaranteed.

[0039] The examples described in the utility model are only used to describe the preferred embodiments of the utility model, and do not limit the utility model concept and scope, and various deformations and improvements of the technical scheme of the utility model made by the engineering and technical personnel in the field without departing from the design idea of the utility model shall fall into the protection scope of the utility model.
