Description

Technical Field

[0001] The present application relates to the field of mine support technology, and in particular to a support device for mine safety engineering protection. Background Art

[0002] The areas where humans mine coal resources in coal-rich mining areas are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. In the process of coal mining, mine collapse accidents often occur. In order to avoid the occurrence of mine collapse accidents, protective support devices are needed to protect the coal mine tunnels.

[0003] Most of the existing support devices for shaft support are two columns, and the tops of the two columns are provided with arch plates for supporting the top of the shaft. The existing arch plate mechanism is fixed and can only support the top of a shaft of a fixed size. During the excavation process of the shaft, the tops of the shafts are not of the same size, and the arched parts of some shafts have size differences. When the arch plates of the traditional support devices are supporting, although their columns can be raised and lowered, the arch plates supporting the top of the shaft cannot be flexibly fine-tuned, resulting in poor support effect on the top of the shaft. Therefore, the present application proposes a support device for mine safety engineering protection. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] like Figures 1-6 As shown, an embodiment of the present application provides a support device for mine safety engineering protection, comprising:

[0028] When the screw rod 3 is rotated, the screw rod 4 and the screw rod 3 are engaged with each other, but are limited by the guide rod 6, so that the screw rod 4 can only move axially and drive the connecting plate 5 to move. One of the connecting plates 5 is a main plate, and the other multiple connecting plates 5 are auxiliary plates. Preferably, the connecting plate 5 located above the center of the arch plate 2 is the main plate, and the connecting plates 5 on the other two sides are auxiliary plates.

[0029] The support member 7 includes several support plates 701 hinged in sequence. The support plates 701 can be straight plates or curved plates with a certain curvature. One of the support plates 701 is fixed to the main plate, and the remaining support plates 701 are respectively in contact with and overlapped with the secondary plates. Preferably, the number of support plates 701 is consistent with the number of the screw rods 4, and they are aligned one by one. The support plate 701 located in the center is the main support plate, and the support plates 701 on the other two sides are secondary support plates. The main support plate is fixed to the connecting plate 5 as the main plate, and the secondary support plates are overlapped with the connecting plate 5 as the secondary plate.

[0030] The driving member 8 is provided on the arch plate 2 and is used to drive several threaded cylinders 3 to rotate synchronously. When supporting the well, the two columns 1 are erected in the well and support the arch plate 2. When adjusting the support for the top of the well, the driving member 8 drives several threaded cylinders 3 to rotate synchronously. When the threaded cylinder 3 rotates, the screw rod 4 matched with its thread moves axially, thereby driving several connecting plates 5 to expand and move synchronously. Since the support member 7 is hinged by multiple support plates 701, and the support plate 701 in the middle is fixed to the connecting plate 5 in the middle, the remaining support plates 70 1 is overlapped with the remaining connecting plates 5, so the support member 7 composed of several support plates 701 is away from the arch plate 2 and contacts the top wall of the well. When adjusted, the support member 7 composed of several support plates 701 always remains parallel to the arch plate 2, thereby effectively supporting the top of the well. It can be fine-tuned according to the top of the well. The gravity of the well is transmitted to the several screw rods 4 through the several support plates 701. Since the threaded fit between the screw rod 4 and the threaded barrel 3 is self-locking, the stress is transmitted to the arch plate 2, and the arch plate 2 effectively supports the top of the well through the two columns 1;

[0031] In this solution, the support member 7 supports the top of the shaft, and the arch plate 2 supports the support member 7 through two columns 1. The support member 7 is composed of several hinged support plates 701. Several screw rods 4 are set on the arch plate 2 to support the several support plates 701 respectively. Since the support plate 701 serving as the auxiliary support plate and the connecting plate 5 serving as the auxiliary plate are overlapped, the support member 7 as a whole can be expanded and fine-tuned, and after fine-tuning, it always remains parallel to the arch plate 2, thereby effectively supporting the top of the shaft, thereby improving practicality.

[0032] like Figure 2 、 Figure 4 and Figure 6As shown, in some embodiments, the driving member 8 includes a first hydraulic push rod 801 arranged on the arch plate 2, and a gear 802 is fixed on each of the threaded cylinders 3. A support plate 803 is installed at the piston end of the first hydraulic push rod 801, and a plurality of racks 804 are fixed on the support plate 803, and the plurality of racks 804 are respectively engaged with the teeth of the plurality of gears 802. When the first hydraulic push rod 801 works, its piston end pushes the support plate 803 horizontally to move, thereby driving the plurality of racks 804 to move. By utilizing the engagement of the teeth of the racks 804 and the gears 802, the plurality of threaded cylinders 3 are driven to rotate synchronously, making the adjustment convenient and stable after adjustment.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, rollers 9 are provided on the remaining several sub-plates, and several rollers 9 are respectively rolled and overlapped with the remaining several support plates 701. Since the sub-plates are in contact and overlapped with the support plates 701 serving as sub-support plates, the provided rollers 9 can reduce the contact friction between the sub-plates and the support plates 701 during adjustment without affecting the stable support of the sub-plates to the support plates 701, thereby making the adjustment smoother.

[0034] like Figure 2 As shown, in some embodiments, the column 1 includes a bottom column 101, an inner column 102 is slidably inserted in the bottom column 101, a second hydraulic push rod 103 is connected between the bottom column 101 and the inner column 102, and the arch plate 2 is connected to the two inner columns 102. In actual use, the height of the wellbore also varies. The bottom column 101 is placed on the ground, and the second hydraulic push rod 103 works, and its piston end drives the inner column 102 to rise and fall, so that the overall height of the column 1 can be adjusted, making it more effective in supporting the wellbore.

[0035] like Figure 1 As shown, in some embodiments, diagonal bracing members 10 are provided on both inner columns 102, and the two diagonal bracing members 10 respectively support the support plates 701 located at both ends. By providing diagonal bracing members 10 on the two inner columns 102, the two diagonal bracing members 10 are respectively used to support the support plates 701 located at the two ends. As long as several support plates 701 are in an arched state, the two ends of the support member 7 are supported by the two diagonal bracing members 10, which can further improve the overall bearing capacity of the support member 7, thereby improving the support effect on the shaft.

[0036] like Figure 5As shown, in some embodiments, the diagonal support member 10 includes a support rod 1001 hinged at the end of the support plate 701, and a plurality of cross bars 1002 are arranged in an array along the height direction of the inner column 102. A groove is provided on the inner column 102, and the plurality of cross bars 1002 are fixed in the groove. A clamping block 1003 is provided at the end of the support rod 1001, and the clamping block 1003 is engaged with the cross bar 1002. A clamping slot is provided on the clamping block 1003, and the cross bar 1002 is engaged with the clamping slot. When the support member 7 is expanded and adjusted as a whole, the height of the support plates 701 at both ends will also change. At this time, the support rod 1001 is rotated around the hinge point, and the clamping block 1003 is clamped on the corresponding cross bar 1002, so as to support the support plates 701 at both ends, thereby achieving the support and strengthening of the support member 7 as a whole.

[0037] like Figure 5 As shown, in some embodiments, the support rod 1001 includes an outer rod 10011 hinged on the support plate 701, and the inner rod 10012 is inserted into the inner thread of the outer rod 10011, and the block 1003 is rotatably set at the free end of the inner rod 10012. After the support member 7 is expanded and adjusted as a whole, the heights of the support plates 701 on both sides are different with different adjustments. The support rod 1001 is composed of the outer rod 10011 and the inner rod 10012, and the two are threaded together. The inner rod 10012 is twisted and rotated, so that the overall length of the support rod 1001 can be adjusted, so that the block 1003 can better be clamped and matched with the corresponding cross bar 1002 to achieve the effect of fine-tuning. At the same time, the threaded cooperation of the inner rod 10012 and the outer rod 10011 is self-locking to ensure stability after fine-tuning.

[0038] like Figure 1 and Figure 4 As shown, in some embodiments, a horizontal plate 11 is connected between the two inner columns 102, and a plurality of vertical rods 12 are connected in an array between the horizontal plate 11 and the arch plate 2. The connected horizontal plate 11 is used to strengthen the connectivity between the two columns 1, and the vertical rods 12 are connected between the horizontal plate 11 and the arch plate 2 to further improve the load-bearing performance of the arch plate 2 and further improve the supporting effect on the top of the shaft.
