Description

Technical Field

[0001] The utility model relates to the technical field of mine shaft hoisting, in particular to a quick disassembler of a wedge-shaped connecting device for shaft hoisting. Background Art

[0002] The wedge-shaped connecting device for vertical shaft hoisting is an important component used in mine vertical shaft hoisting operations. During mine vertical shaft hoisting, the hoisting wire rope needs to be adjusted and replaced regularly, so the connecting hoisting rope and the wedge-shaped rope ring need to be disassembled.

[0003] Currently, there are two ways to disassemble the connection between the lifting rope and the wedge rope ring: manual and mechanical. Manual methods include hammering and heating with flames, which are time-consuming and labor-intensive, and may damage the lifting wire rope and the wedge rope ring; commonly used mechanical tools are relatively bulky and cumbersome to install and fix. Utility Model Content

[0004] The present invention relates to a quick disassembler for a wedge-shaped connection device for vertical shaft hoisting, which solves the problems of existing methods for disassembling the connection between the hoisting rope and the wedge-shaped rope ring, such as manual hammering, flame heating, etc., which are time-consuming and labor-intensive, and may damage the hoisting wire rope and the wedge-shaped rope ring, and the commonly used mechanical tools are relatively bulky and cumbersome to install and fix.

[0005] In a first aspect of the present disclosure, a quick detacher of a wedge-shaped connection device for vertical shaft lifting is provided, which specifically includes: a lower wall plate, a clamping strip, a wedge-shaped rope ring, a lifting wire rope, an upper wall plate, a hinge support, a hydraulic cylinder and a tensioning block; the lower wall plates are provided with two, and the inner sides of the lower wall plates are fixedly connected with two clamping strips by bolts, the clamping strips are connected to the two lower wall plates, and the bottom of the lower wall plates is connected to the vertical shaft; the inner sides of the lower wall plates are connected with a wedge-shaped rope ring, and the interior of the lower wall plates is connected with a lifting wire rope; the inner sides of the lower wall plates are fixedly connected with the upper wall plates by bolts, the top ends of the two upper wall plates are fixedly connected by bolts, and a hinge support is installed inside the upper wall plates, and the hinge support is connected to the two upper wall plates; a hydraulic cylinder is installed at the bottom of the hinge support, and a tensioning block is connected to the bottom of the hydraulic cylinder, and the tensioning block is connected to the wedge-shaped rope ring.

[0006] Furthermore, one of the clamping strips is vertical, the other clamping strip is inclined, and the distance between the top ends of the two clamping strips is smaller than the distance between the bottom ends.

[0007] Furthermore, the outer side of the wedge-shaped rope ring contacts the lifting wire rope, the lifting wire rope contacts the inner sides of the two clamping blocks, and the lifting wire rope is located between the clamping blocks and the wedge-shaped rope ring.

[0008] Furthermore, the wedge-shaped rope ring is slidably connected to the inner sides of the two lower wall panels on both sides. When the wedge-shaped rope ring moves upward, the distance between the wedge-shaped rope ring and the two clamping blocks is reduced, so that the lifting wire rope is in close contact with the clamping blocks and the wedge-shaped rope ring.

[0009] Furthermore, the cross section of the hinge support is in the shape of an I, a T-shaped connecting groove is provided inside the upper wall plate, and the opposite ends of the hinge support are connected to the T-shaped connecting groove provided on the upper wall plate.

[0010] Furthermore, a trapezoidal connecting groove is provided on the top of the wedge-shaped rope ring, and the bottom of the tensioning block is trapezoidal, and the bottom of the tensioning block is connected to the trapezoidal connecting groove provided on the wedge-shaped rope ring.

[0011] Furthermore, the hydraulic cylinder is in an inverted shape, the top of the hydraulic cylinder body is rotatably connected to the bottom of the hinge support, a connecting hole is provided inside the tensioning block, and the bottom end of the piston rod of the hydraulic cylinder is fixedly connected to the connecting hole provided in the tensioning block. When the hydraulic cylinder drives the tensioning block to move upward, the tensioning block drives the wedge rope ring to move upward synchronously, thereby achieving a clamping contact effect on the lifting wire rope. When the lifting wire rope needs to be adjusted and replaced, when the hydraulic cylinder drives the tensioning block to move downward, the tensioning block drives the wedge rope ring to move downward synchronously, the distance between the wedge rope ring and the two clamping bars increases, and the lifting wire rope is separated from the two clamping bars.

[0012] The utility model provides a quick detacher for a vertical shaft hoisting wedge-shaped connection device, which has the following beneficial effects:

[0013] When the utility model is in use, the wedge-shaped rope ring moves upward, and the distance between the wedge-shaped rope ring and the two clamping blocks is reduced, so that the lifting wire rope is in close contact with the clamping blocks and the wedge-shaped rope ring, ensuring the contact force effect of the lifting wire rope, thereby ensuring the safety of the vertical shaft lifting operation.

[0014] In addition, the tensioning block is connected to the trapezoidal connecting groove. When the hydraulic cylinder drives the tensioning block to move upward, the tensioning block drives the wedge-shaped rope ring to move upward synchronously, thereby achieving a clamping contact effect on the lifting wire rope. When the lifting wire rope needs to be adjusted and replaced, the hydraulic cylinder drives the tensioning block to move downward, and the tensioning block drives the wedge-shaped rope ring to move downward synchronously. The distance between the wedge-shaped rope ring and the two clamping bars increases, and the lifting wire rope is separated from the two clamping bars. The lifting wire rope can be adjusted and replaced, which is simpler and saves time.

[0015] In addition, hydraulic driving force replaces the traditional manual use of heavy tools such as sledgehammers and pneumatic picks, which is safer and more reliable, and improves work efficiency and the level of mine automation; avoids damage to the lifting wire rope and wedge rope ring caused by manual hammering, and realizes the rapid and non-destructive disassembly of the lifting wire rope, ensuring the safe and reliable operation of the lifting system. The overall structure is simple and easy to disassemble and assemble.
