Description

Quick installation device of mining single track anchor rod and hoist

Technical Field

The utility model belongs to the technical field of mining equipment, concretely relates to quick installation device of mining single track anchor rod and hoist.

Background

In the underground coal mine in China, the transportation of materials mostly depends on a ground track, and a reel or a stepless winch steel wire rope is adopted for traction transportation, but the operation mode depending on the ground track has many defects, firstly, a roadway must have enough sectional area with width and height to accommodate the total area of a laid track and a vehicle, secondly, the ground track transportation is carried out, particularly, uneven (more than or equal to 4 degrees) gradient transportation is carried out, the connection between the vehicle and the steel wire rope is very critical, and since the vehicle and the steel wire rope are not firmly connected for many years, the occurrence of runaway and sports accidents happens, great economic loss is caused to material and human safety, the ground track transportation is a traditional transportation method, the relative safety coefficient is not high, and the transportation method is old. In recent years, the monorail crane takes the position occupying the height space of a roadway as an advantage, namely, an idle top plate at the high position of the roadway is used as a foundation, a hanging rail is installed at the top, the monorail crane lifts a heavy object and transports and walks in the air, and the transportation mode is a rail installed by taking the idle top plate at the high position of the roadway as a foundation, so that a belt, a chute and other transportation roadways can be directly communicated with the underground, and the monorail crane is very convenient. However, the track must be hung and installed at the top of the roadway by using anchor rods, the installation of the anchor rods is a very complicated process, and the traditional installation mode is as follows: drilling with a drill rod → pulling out the drill rod → loading a cartridge → installing a stirrer → advancing the drill rod → stirring → withdrawing the stirrer with a wrench → screwing on a special connecting ring of the monorail crane, the process is complex, the special connecting ring is not suitable to be screwed on directly, and the complex process causes low efficiency and low safety factor.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in the figure, the quick installation device of mining single track anchor rod and hoist, includes drilling rod 1, fixture 2 and go-between 3, the center at fixture 2's both ends is equipped with recess I4 and recess II 5 respectively, and fixture 2's terminal surface is equipped with connecting hole I6, and connecting hole I6 is located in the middle of recess I4 and recess II 5, the center of go-between 3's one end is equipped with recess III 7, and the center of the other end is equipped with and lifts by crane the screw rod assorted screw thread mouth 8 of stock, and the terminal surface of recess III 7 is equipped with connecting hole II 9 that corresponds with connecting hole I6, and I4 welded connection in recess of drilling rod 1's one end and fixture 2 one end, recess III 7 and II 5 of the recess of the fixture 2 other end of go.

The cross section of the drill rod 1 is in a regular six-deformation shape.

The width of the groove I4 is larger than that of the drill rod 1.

And reinforcing plates 10 are respectively arranged on two sides of the groove II 5.

The length of recess II 5 and the diameter phase-match of recess III 7, the height phase-match of the height of recess II 5 and recess III 7.

The thickness of the groove II 2 is matched with the width of the groove III 7.

The axial line of the drill rod 1, the axial line of the groove I4, the axial line of the groove II 5, the axial line of the groove III 7 and the axial line of the threaded opening 8 are positioned on the same straight line.

Drilling rod 1 is hexagonal drilling rod, and fixture 2 is the "fan-shaped" device that has the alloy steel sheet preparation of certain thickness, and drilling rod 1 and fixture 2 are welded as a whole with special stainless steel alloy welding rod, must ensure centrality and welding quality, ensure the utility model discloses the vibrations that cause because of the eccentricity during rotation take place, and the diameter of connecting hole I6 of fixture 2 is phi 20mm, and is identical with connecting hole II 9 above the go-between 3, and reinforcing plate 10 plays to add the muscle and lock the dual function of the single track go-between of hoisting accessory, and the screw hole 8 of go-between 3 is supporting with the screw rod of hoisting the stock.
