Description

Technical Field

[0001] The utility model belongs to the technical field of installation of hydraulic supports for large-angle working surfaces, and in particular relates to an installation device of hydraulic supports for large-angle working surfaces. Background Art

[0002] In the process of coal mining, hydraulic supports are often needed to carry out supporting operations in the tunnel.

[0003] During the installation and construction process, since the working face is cut into an inclined tunnel, the hydraulic support enters from the return air chute. Facing the inclined tunnel, if the hydraulic support is installed with a traditional forklift in conjunction with the adjustment direction, the forklift cannot push the hydraulic support on such a large slope, and the support is very likely to tip over and hit the forklift driver during the pushing process, posing a great threat to the safety of the vehicle driver.

[0004] The specific reason is that the hydraulic support components are large and extremely heavy, and are very difficult to install in the geographical environment of an inclined tunnel working face.

[0005] Specifically, when the hydraulic support is lowered to the working surface, it is difficult to adjust the angle of the hydraulic support to the correct position in the narrow working surface. Large mechanical equipment, such as cranes, cannot enter the narrow tunnel. Therefore, in the actual operation process, when slope forklifts and cranes cannot be used for construction, the operation becomes very difficult.

[0006] However, the bulky hydraulic support is difficult to pull due to its low stability when supported on the inclined surface. In addition, it is also difficult to prevent the hydraulic support from tipping over during the pulling process.

[0007] Therefore, if it is possible to save effort and have high flexibility, and keep the hydraulic support from tipping over during the process of adjusting the posture of the hydraulic support, it will be of great significance to improve the installation efficiency of the hydraulic support during the construction process. Utility Model Content

[0008] Based on the above background, the purpose of the utility model is to provide a hydraulic support installation device for a large-angle working surface.

[0009] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0010] A large-angle working surface hydraulic support installation device, comprising an adjusting winch mechanism for adjusting the angle of the hydraulic support and an anti-tilting winch mechanism for pulling to prevent the hydraulic support from tipping over;

[0011] The adjusting winch mechanism and the anti-tilt winch mechanism are arranged in staggered positions;

[0012] The adjusting winch mechanism and the anti-tilt winch mechanism both include a winch frame, on which a wire rope pulling assembly is installed, and the wire rope pulling assembly includes a wire rope drum rotatably connected to the winch frame, on which a wire rope for pulling the hydraulic support is wound;

[0013] The winch frame is equipped with a plurality of type I support arms and a plurality of type II support arms;

[0014] The type I support arm is used to be fixed on the top of the tunnel, and the type II support arm is supported on the top beam of the installed hydraulic support.

[0015] Preferably, the winch frame includes side frame portions arranged front and rear;

[0016] The type I support arm and the type II support arm are both fixedly mounted on the side frame portion, and a base portion is integrally formed at the bottom of the side frame portion.

[0017] Preferably, connecting beams are welded between the tops of the side frame parts.

[0018] Preferably, the type I support arm includes an inclined first support arm and a plurality of vertically arranged first support arms;

[0019] The type I support arm is fixedly connected to the side frame portion at the front portion.

[0020] Preferably, the type II support arm includes an inclined second support arm and a plurality of vertically arranged second support arms;

[0021] The type II support arm is fixedly connected to the side frame portion at the rear side.

[0022] Preferably, the first and second diagonal support arms are arranged to be inclined and close to each other.

[0023] Preferably, the hydraulic cylinder of the hydraulic support is hung with a first steel wire rope, and the first steel wire rope is wound on a steel wire rope drum on the adjusting winch mechanism.

[0024] Preferably, a second steel wire rope is hung on the support of the hydraulic support, and the second steel wire rope is wound on a steel wire rope drum on the anti-tilt winch mechanism;

[0025] During the pulling process of the first steel wire rope, the hydraulic support rotates and adjusts the angle with the hydraulic cylinder as a fulcrum, and the second steel wire rope cooperates with the first steel wire rope to pull the hydraulic support to prevent the hydraulic support from tipping over.

[0026] Preferably, the first steel wire rope and the second steel wire rope are steel wire ropes with a size of φ32mm.

[0027] The utility model has the following beneficial effects:

[0028] 1. During the working process, the wire rope drum is wound. At this time, the first wire rope pulls one end of the hydraulic support in an oblique manner. At this time, the hydraulic support uses the ground as a fulcrum (the cylinder barrel of the hydraulic cylinder of the hydraulic support is supported on the ground) to rotate and adjust the posture. In the process of adjusting the posture, the second wire rope is pulled in cooperation with the first wire rope to pull the hydraulic support (the pulling direction is the opposite direction of the hydraulic support's tipping). Under the action of the pulling force, the hydraulic support is not easy to tip over. In this way, the bulky hydraulic support can be pulled and adjusted to the correct angle posture in an extremely labor-saving manner.

[0029] 2. Fix the winch frame to the top of the tunnel by using the Class I support arm. Use the Class II support arm to support the top beam of the installed hydraulic support to further fix the winch in place, thus preventing the winch from loosening during operation.

[0038] like Figure 1-3 As shown, a hydraulic support installation device for a large-angle working surface includes an adjusting winch mechanism for adjusting the angle of the hydraulic support and an anti-tilt winch mechanism for pulling to prevent the hydraulic support 3 from tipping over. During the construction process, the adjusting winch mechanism is used to pull the hydraulic support 3 being installed so that the hydraulic support 3 being installed rotates relative to the ground to adjust its posture, and during the rotation and adjustment process, the anti-tilt winch mechanism is used to pull the hydraulic support 3 to prevent it from tipping over (once the heavy hydraulic support 3 tips over, it is very difficult to lift and straighten it).

[0039] Specifically, the adjusting winch mechanism and the anti-tilting winch mechanism are staggered in position. By staggering, the adjusting winch mechanism can be conveniently pulled to adjust the posture while the anti-tilting winch mechanism is pulled in coordination to avoid tilting.

[0040] Specifically, both the adjusting winch mechanism and the anti-tilt winch mechanism include a winch frame, on which a wire rope pulling assembly is installed, and the wire rope pulling assembly includes a wire rope drum 2 rotatably connected to the winch frame, and a wire rope for pulling the hydraulic support 3 is wound on the wire rope drum 2. According to the existing conventional method, bearing seats rotatably connected to the wire rope drum 2 are respectively installed on both sides of the top of the winch frame, and the rotating shafts at both ends of the wire rope drum 2 are rotatably connected to the bearing seats. At the same time, like the existing winch, a motor (not shown in the figure) for driving the wire rope drum 2 to rotate is fixedly installed on the winch frame.

[0041] At the same time, the winch frame is equipped with several Class I support arms and several Class II support arms; the Class I support arms are used to be fixed on the top of the tunnel, and the Class II support arms are supported on the top beam of the installed hydraulic support (multiple hydraulic supports need to be installed in the tunnel, and the position of the winch is arranged at the position of the installed hydraulic support, and is supported on the top beam of the installed hydraulic support by the Class II support arms).

[0042] The winch frame is fixed to the top of the tunnel by using Class I support arms (i.e., the first support arm 31 and the first support arm 32 described below). The winch frame is supported on the top beam of the installed hydraulic support 3 by using Class II support arms (i.e., the second support arm 41 and the second support arm 42 described below). The specific reason is that the winch frame is located below the installed hydraulic support, and the Class II support arms are just located below the installed hydraulic support and cannot be supported to the top of the tunnel. Therefore, this method is used to support the top beam of the hydraulic support 3 to support and fix the winch frame. This method can fully fix both sides of the winch, improve stability during operation, and prevent the winch from loosening. After the winch is fixed in the above manner, the hydraulic support being installed is pulled to adjust the posture for installation.

[0043] Specifically, the winch frame includes side frames arranged at the front and rear; the type I support arms and a plurality of type II support arms are fixedly mounted on the side frame 11, and the bottom of the side frame 11 is integrally formed with a base 12. At the same time, a connecting beam 13 is welded between the tops of the side frames 11.

[0044] The type I support arm includes an inclined first support arm 31 and two vertically arranged first support arms 32 .

[0045] The above-mentioned type I support arm is fixedly connected to the side frame part 11 at the front side. The type II support arm includes an inclined second support arm 41 and two vertically arranged second support arms 42; the type II support arm is fixedly connected to the side frame part 11 at the rear side.

[0046] The first and second support arms 31 and 41 are tilted and arranged close to each other.

[0047] The hydraulic cylinder of the hydraulic support 3 is hung with a first steel wire rope 22, which is wound on the steel wire rope drum 2 on the adjusting winch mechanism. The support of the hydraulic support 3 is hung with a second steel wire rope 21, which is wound on the steel wire rope drum 2 on the anti-tilt winch mechanism.

[0048] Specifically, the first steel wire rope 22 is hung at the rear end position of the left side of the hydraulic cylinder of the hydraulic support 3 being installed, and the second steel wire rope 21 is hung at the right end position of the support of the hydraulic support 3 being installed. During the working process, under the winding of the steel wire rope drum 2, at this time, the first steel wire rope 22 pulls one end of the hydraulic support 3 in an oblique pulling manner, and the hydraulic support 3 being installed at this time uses the ground as a fulcrum (the cylinder barrel of the hydraulic cylinder of the hydraulic support 3 is supported on the ground) to rotate and adjust the posture. During the posture adjustment process, the second steel wire rope 21 is pulled in coordination with the first steel wire rope 22 to pull the hydraulic support 3 (the pulling direction is the opposite direction of the tipping of the hydraulic support 3). Under the action of the pulling force, at this time, the hydraulic support 3 being installed is not easy to tip over. In this way, the heavy hydraulic support 3 can be pulled to the correct angle posture in an extremely labor-saving manner.

[0049] The first steel wire rope 22 and the second steel wire rope 21 are thickened steel wire ropes to ensure the safety of pulling, and specifically, the steel wire ropes are φ32mm in size.

[0050] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
