Description

Technical Field

[0001] The utility model relates to the field of hydraulic support installation equipment for a coal mine recovery working face, in particular to a hydraulic support installation and adjustment device. Background Art

[0002] Most of the traditional hydraulic support adjustment devices are shown in the Chinese utility model patent entitled "Hydraulic support installation and adjustment device" and application number "202120477988.6" applied by the applicant on March 5, 2021, and the Chinese invention patent application entitled "A wear-resistant chain hydraulic support adjustment device" and application number "202110843248.4" applied on July 26, 2021. The basic components of this type of hydraulic support adjustment device include a slide, a traction mechanism and a pushing mechanism. When working, one end of the chain needs to be connected to the traction mechanism, and the other end is hooked on the hydraulic support, so as to achieve pulling and 90° adjustment of the hydraulic support. After the adjustment is completed, the hydraulic support can be pushed out of the slide through the pushing mechanism and finally pushed to the target placement position.

[0003] In recent years, with the widespread use of downhill supports, miners will first arrange downhill supports parallel to the length of the tunnel in the initial stage of mining. When mining reaches the next stage, the downhill supports will be adjusted 90° and supplemented with an appropriate amount of conventional supports, such as Figure 1a As shown in the figure, the traditional hydraulic support transfer device cannot take into account the construction of both the downhill support and the conventional support. Specifically:

[0004] like Figure 1a As shown in the figure, although the size and orientation of the down-mountain bracket and the conventional bracket are the same before the adjustment, when the down-mountain bracket is arranged, it is necessary to remove the support of the down-mountain bracket to be installed first, and then remove the support of the next down-mountain bracket after the adjustment is completed and the hydraulic bracket is installed in place. In this way, when the support of the current down-mountain bracket is removed, the next down-mountain bracket and the hydraulic bracket in front of it that has been adjusted and installed in place will be formed as shown in the figure. Figure 1a The empty top area shown, therefore, the length of the hydraulic support adjustment device should not be too long, otherwise it will cause the empty top to be too long, which will bring great safety hazards.

[0005] The transportation of conventional supports usually requires the use of a monorail crane mechanism, which must have a relatively long monorail crane head (about 10 meters). Therefore, in order to avoid excessive friction between the conventional support (weighing about 50 tons) and the ground after the lifting, it is necessary to extend the length of the hydraulic support transfer device so that the hydraulic support transfer device can at least take over part of the conventional support after the lifting, and then it can be easily pulled into the hydraulic support transfer device for adjustment and installation.

[0006] Taking the above two points into consideration, if the hydraulic support transfer device is lengthened to adapt to the monorail crane, the empty top distance will be extremely long (more than 10 meters) during the process of removing the support for adjustment and installation of the downhill support, which is extremely dangerous. However, if the hydraulic support transfer device is shortened to adapt to the downhill support, the conventional support will not be able to fall onto the hydraulic support transfer device after the lifting is completed. Once the conventional support falls to the ground, the difficulty of pulling it onto the hydraulic support transfer device will increase exponentially.

[0007] In summary, the traditional hydraulic support shifting device cannot take into account the construction of both downhill supports and conventional supports, which brings great trouble to underground construction. Utility Model Content

DETAILED DESCRIPTION

[0048] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0049] like Figure 1-9 As shown, this case includes a slide, a traction mechanism and a push mechanism;

[0050] like Figure 3-6 As shown, the slide includes a detachably connected Shunshan bracket slide 2 and a push slide 4. The length of the Shunshan bracket slide 2 is smaller than the push slide 4, and the two are hinged together. The Shunshan bracket slide 2 is located on the left or right side of the push slide 4.

[0051] like Figure 7 As shown, the down-mountain support slide 2 and the push slide 4 are against each other, and the two are connected by a hinge block 10, and the hinge block 10 simultaneously hinges the down-mountain support slide 2 and the push slide 4. Thus, while realizing a detachable connection, the two can maintain better connection stability after installation.

[0052] A transfer ramp 5 is also provided at the rear ends of the Shunshan support slide 2 and the push slide 4, and the transfer ramp 5 is also connected to the Shunshan support slide 2 and the push slide 4 through a hinge.

[0053] A guide ramp 7 rotatably connected to the rear end of the Shunshan support slide 2 is provided.

[0054] During specific use, since the length of the Shunshan bracket slide 2 is relatively small, after the support of the Shunshan bracket to be installed is removed, the empty top formed between the next Shunshan bracket and the hydraulic bracket in front of it that has been adjusted and installed in place can be within a safe range, thereby effectively avoiding the safety hazards caused by the excessive length of the empty top.

[0055] The length of the push slide 4 is relatively long, which can leave enough space for the monorail crane head. In this way, after lifting, the hydraulic support adjustment device can at least take over part of the conventional support (in this case, the conventional support is preferably taken over by the transfer ramp 5), and then it can be easily pulled into the hydraulic support adjustment device for adjustment and installation.

[0056] In addition, the transfer ramp 5 and the guide ramp 7 mentioned above also have a flipping function, specifically:

[0057] like Figure 8 , 9 As shown, the transfer ramp 5 is rotatably connected to the rear end of the push slide 4, and includes a split part 1 and a split part 2 which are hinged to each other. A first flip cylinder 6 is hinged on the side wall of the split part 1, and a hinge seat is fixedly connected to the side wall of the split part 2. The cylinder body of the first flip cylinder 6 is hinged to the split part 1, and the cylinder body of the first flip cylinder 6 is hinged to the hinge seat. In this way, on the one hand, when part of the conventional bracket falls on the transfer ramp and the conventional bracket needs to be pulled to the push slide, the first flip cylinder 6 can be retracted to lift the split part 2, thereby providing auxiliary support for the conventional bracket to be pulled, so as to reduce the pulling resistance. On the other hand, when the push slide 4 moves backward, the lifting of the split part 2 can also effectively prevent the problem of bottom drilling.

[0058] like Fig.10 , 11 As shown in 12, the guide ramp 7 is rotatably connected to the rear end of the Shunshan bracket slide 2, and a second turning cylinder 8 for driving the guide ramp 7 to turn over is provided in the Shunshan bracket slide 2;

[0059] The Shunshan support slide 2 begins to have a cylinder accommodating groove arranged along its length direction, the cylinder rod of the second flip cylinder 8 is hinged in the cylinder accommodating groove, and the cylinder rod of the second flip cylinder 8 is hinged to a wedge-shaped push block, the wedge-shaped push block can be slidably accommodated in the cylinder accommodating groove, and abuts against the bottom surface of the guide ramp 7. In particular, when the wedge-shaped push block is fully extended below the guide ramp 7, the guide ramp 7 and the top of the Shunshan support slide 2 can form a plane, even if the length of the Shunshan support slide 2 is designed to be short, the extension of the guide ramp 7 can also increase the operating space of the Shunshan support, avoiding a series of problems such as the support falling and motion interference when the Shunshan support is rotated and adjusted due to the short length of the Shunshan support slide 2. In addition, when the wedge-shaped push block is flat against the guide ramp 7 to support it, the second flip cylinder 8 can also be in a state without force.

[0060] On the other hand, when part of the Shunshan bracket falls on the guide ramp and it is necessary to pull the Shunshan bracket to the Shunshan bracket slide, the second flip cylinder 8 can be extended to lift the guide ramp 7, thereby providing temporary auxiliary support for the Shunshan bracket to be pulled, so as to reduce the pulling resistance.

[0061] In addition, in order to prevent the guide ramp 7 from being accidentally stuck and unable to fall, a reset chain can be added between the wedge-shaped push block and the bottom surface of the guide ramp 7, and the two ends of the reset chain are respectively connected to the rear end surface of the wedge-shaped push block and the bottom surface of the guide ramp 7, so that the guide ramp 7 is pulled down and reset when the wedge-shaped push block is reset.

[0062] About temporary support organizations:

[0063] A temporary support mechanism is also connected to one side of the Shunshan support slide 2, and the temporary support mechanism includes a hydraulic push rod 9, and the bottom end of the hydraulic push rod 9 is hinged to one side of the Shunshan support slide 2;

[0064] A straightening cylinder 91 is also provided at the lower part of the hydraulic push rod 9 , the cylinder body of the straightening cylinder 91 is hinged to one side of the Shunshan support slide 2 , and the cylinder rod of the straightening cylinder 91 is hinged to the lower part of the hydraulic push rod 9 .

[0065] In the above, the bottom end of the hydraulic jack 9 and the cylinder body of the straightening cylinder 91 can be directly hinged to the Shunshan support slide 2, or can be hinged to the traction mechanism beside the Shunshan support slide as shown in the figure. Therefore, during use, the hydraulic jack 9 can be supported to a vertical state by the straightening cylinder 91, and then the hydraulic jack 9 can be extended to support it in the empty top position, which plays a role in further avoiding safety accidents such as roof collapse and landslide.

[0066] The traction mechanism includes a traction assembly 1 installed on both sides of the slide, and the traction assembly 1 includes a traction cylinder 11, a guide pulley 12 and a steering pulley 13. The cylinder body of the traction cylinder 11 is hinged to the rear end of the slide, the guide pulley 12 is hinged to the front end of the cylinder rod of the traction cylinder 11, and the steering pulley 13 is hinged to the rear of the traction cylinder 11.

[0067] Fig.15 1 is a schematic diagram of a deflection pulley 13. The deflection pulley 13 is placed in a pulley frame, and a slider 14 is provided on the side of the pulley frame. Figure 3 , 7 As shown, two sides of the slide are provided with slideways, and the slider 14 is slidably assembled in the slideway. The slider 14 slides in the slideway through the drive of the oil cylinder traction 11. The steering pulley 13 is a movable pulley. During the traction process, the stroke is enlarged and the number of chain hanging times is reduced.

[0068] The push assembly 3 in this case can be installed on the Shunshan bracket slide 2 or the push slide 4, or the push assembly 3 can be arranged on the Shunshan bracket slide 2 and the push slide 4 at the same time. The second arrangement is described below as an example:

[0069] The pushing mechanism includes a pushing assembly 3 installed in the simultaneously installed Shunshan support slide 2 and the pushing slide 4, and the pushing assembly includes a pushing cylinder 31 and a pushing device 32;

[0070] A longitudinal groove is provided on the Shunshan support slide 2 and the pushing slide 4, and a pushing device track is provided in the front half of the longitudinal groove; the pushing cylinder 31 is placed in the rear half of the longitudinal groove, and the rear end of the cylinder body of the pushing cylinder 31 is hinged to the rear end of the longitudinal groove, and the front end of the cylinder rod of the pushing cylinder 31 is connected to the pushing device 32, and the pushing device 32 is placed on the pushing device track.

[0071] The pushing device 32 includes a pushing frame 321, a tumbler plate 322 and a pushing tongue plate 323; the pushing frame 321 is hinged at the end of the cylinder rod of the pushing cylinder 31; the tumbler plate 322 is a flap with a pair of right-angled edges, and a pin shaft hole is provided at the right-angle position. The tumbler plate 322 is hinged to the pushing frame 321 through the pin shaft hole, and the horizontal right-angled edge of the tumbler plate 322 is located behind the pin shaft hole; the pushing tongue plate 323 is placed on the pushing device track of the longitudinal groove and is hinged to the front of the pushing frame 321.

[0072] Fig.16 It is a schematic diagram of the structure of the push device. The tumbler plate 322 can be flipped in one direction; the push tongue plate 323 can ensure that the hydraulic support first falls on the push tongue plate when it pushes down the slide, reducing the drop, and the hydraulic support will not tip over due to the large drop. After the hydraulic support completely falls down the slide, the push cylinder retracts and pulls out the push device hydraulic support to the ground, completing the installation of the hydraulic support.

[0073] There are many specific implementation ways of the utility model. The above is only the preferred implementation mode of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the utility model, and these improvements should also be regarded as the protection scope of the utility model.
