Description

Rope guide wheel locking device

Technical Field

The utility model relates to the technical field of a rope replacing vehicle, in particular to a rope guide wheel locking device used in the process of replacing a rope body of the rope replacing vehicle.

Background

The multi-rope friction type lifting system is characterized in that a steel wire rope is lapped on a friction wheel by utilizing the principle of flexible body friction transmission, and a heavy object and personnel are lifted or lowered by utilizing the friction force between the steel wire rope and a liner. The multi-rope friction type lifting system adopts a plurality of steel wire ropes to lift simultaneously, has good safety, but has a plurality of advantages and also has some disadvantages. Because the number of the steel wire ropes is large, the suspension, the adjustment and the maintenance are complex and difficult, various damages, particularly abrasion, can be caused because the steel wire ropes are used in a severe environment for a long time and are simultaneously subjected to the action of alternating load, and the phenomena of plasticity extension, wire breakage, distortion, corrosion and the like can be caused because the steel wire ropes are frequently used for a long time, so that the steel wire ropes must be adjusted or replaced regularly. In order to improve the rope changing efficiency and ensure the safety of rope changing, a rope changing vehicle is adopted to change a steel wire rope in the prior art. The rope changing trolley generally comprises a support, a chain wheel rotatably mounted on the support, a chain mounted on the chain wheel, a clamping block and a rope guide wheel, wherein the chain comprises an upper chain and a lower chain, clamping bearing bodies are fixedly mounted on the upper chain and the lower chain, the clamping block comprises an upper beam body and a lower beam body, the upper beam body and the lower beam body move oppositely through the acting force of a hydraulic cylinder, clamping force is provided for the clamping bearing bodies mounted on the upper chain and the lower chain, and a steel wire rope is flexibly clamped by the chain to realize continuous rope conveying by the chain.

When the rope changing vehicle is used for changing the rope, the steel wire rope is clamped between the clamping bearing bodies of the upper chain and the lower chain after bypassing the rope guide wheel from top to bottom, and then the upper chain and the lower chain are driven to rotate simultaneously, so that the steel wire rope is conveyed. However, when the steel wire rope runs after passing through the rope guide wheel, the whole rope guide wheel is lifted upwards due to the tensile force of the steel wire rope, and at the moment, if the tensile force is too large, the pin shaft at the rear part of the rope guide wheel is easy to deform, even has the risk of fracture, not only influences the construction process, but also has great potential safety hazard.

Referring to fig. 1 as appropriate, the present invention provides a pulley locking apparatus of a basic embodiment including a first connecting member 1 having a first connecting end, a second connecting member 2 having a second connecting end, a locking member 3 and a driving member 4. The first connecting end of the first connecting piece 1 can be connected to the rope guide wheel 6, and the second connecting end of the second connecting piece 2 can be connected to the foundation beam; or the first connecting end of the first connecting piece 1 can be connected to the foundation beam and the second connecting end of the second connecting piece 2 can be connected to the rope guide 6. The foundation beam is a beam body located at the working position for replacing the rope and can be fixedly connected with the wellhead structure.

The second connecting piece 2 can slide on the first connecting piece 1, and the driving piece 4 can drive the second connecting piece 2 to slide on the first connecting piece 1 so that the first connecting end is close to the second connecting end. A slideway can be arranged on the first connecting piece 1 or the second connecting piece 2, and the second connecting piece 2 or the first connecting piece 1 can be inserted into the slideway and can slide back and forth in the slideway; or the first connecting piece 1 and the second connecting piece 2 can be connected in a sliding way through a guide rail sliding block.
