Description

Technical Field

[0001] The utility model relates to the technical field of supporting equipment, in particular to a supporting device for coal mining which is easy to install. Background Art

[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It is 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 mining in an underground coal mine, the mined tunnels need to be supported to prevent collapse, so as to protect the safety of the workers.

[0003] The Chinese patent "A support device for coal mining that is easy to install" authorization announcement number "CN 213016400U" is provided with a first support rod, a second support rod, a fixing ring, a sleeve, a support column, a threaded rod, a nut, a telescopic support rod, an arc-shaped support plate, an adjusting rod and a threaded ring. When in use, the support column can be adjusted in height through the sleeve setting and fixed through the threaded ring, which is convenient for adjusting the support according to the height of the tunnel. The first support rod and the second support rod can be pulled out to both sides to support both sides of the tunnel and fixed and adjusted through the fixing ring. The equipment has a simple structure, is easy to adjust, and is relatively convenient to use.

[0004] In the above scheme, the arc-shaped support plate and the support block can support the tunnel. However, when the arc-shaped support plate is used to support the top of the tunnel, the height of the four support columns and the sleeves need to be adjusted separately, and the distance between the two support blocks and the two sides of the tunnel also needs to be adjusted separately, which is more complicated.

[0005] Therefore, a support device for coal mining which is easy to install is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a support device for coal mining that is easy to install in order to solve the above-mentioned problems, thereby improving the problem that when using an arc support plate to support the top of the tunnel, the height of the four support columns and the sleeves need to be adjusted separately, and the distance between the two support blocks and the two sides of the tunnel also needs to be adjusted separately, which is a cumbersome operation.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a support device for coal mine mining that is easy to install, comprising: a fixed plate, the top end of the fixed plate is fixedly connected with support rods distributed in equal columns, and the bottom end of the fixed plate is provided with a mounting mechanism; wherein, the mounting mechanism comprises four fixed columns, the inner wall of the fixed column is slidably connected with the support column, the top end of the support column passes through the fixed column and is provided with a mounting groove, the four corners of the bottom end of the fixed plate are fixedly connected with a clamping rod, the surfaces of the two longitudinal fixed columns are fixedly connected with the mounting plate, the inner wall of the mounting plate is fixedly connected with an electric hydraulic push rod, the telescopic end of the electric hydraulic push rod is fixedly connected with a connecting plate, the two ends of the connecting plate are respectively fixedly connected to the surfaces of the two longitudinal support columns, and the top end of the fixed plate is provided with a mounting assembly.

[0008] Preferably, the mounting assembly includes an electric push rod fixedly connected to the top of the fixed plate, the telescopic end of the electric push rod is fixedly connected to a circular plate, the inner wall of the fixed plate is slidably connected to two mounting rods, the top of the mounting rod is fixedly connected to a fixed block, the top of the fixed block passes through the fixed plate and is hinged to a connecting rod, the other ends of the two connecting rods are hinged to the surface of the circular plate, and one end of the mounting rod passes through the fixed plate and is fixedly connected to a support plate. Under the action of the electric push rod and the two connecting rods, it is conducive to the two mounting rods pushing the corresponding support plates to move at the same time to fix the two sides of the lane, without adjusting the distance between the two support plates separately, the operation is simple, and it is more convenient to use, which effectively improves the work efficiency.

[0009] Preferably, the outer surface of the support plate is provided with grooves distributed in a rectangular array, and the openings of the grooves are trumpet-shaped. When the support plate is used to fix the two sides of the lane, under the action of the multiple grooves, some of the protrusions at the fixed position of the support plate will enter the grooves, thereby increasing the contact area of ​​the support plate when fixing the lane, and increasing the friction between the contact surface of the support plate and the lane, thereby improving the support effect of the support plate on the two sides of the lane.

[0010] Preferably, the surface of the clamping rod is fixedly connected to a limiting block, and the inner wall of the installation slot is provided with a limiting slot, and the shape of the limiting slot matches the shape of the limiting block, so as to avoid rotation when the clamping rod is clamped with the installation slot, and ensure the stability of the installation of the fixing plate on the four support columns.

[0011] Preferably, the middle portion of the support rod is bent into an arc shape, which is conducive to better supporting the top of the lane.

[0012] Preferably, a slide groove matching the fixing block is provided at the top of the fixing plate, and the surface of the fixing block is slidably connected to the inner wall of the slide groove, which is beneficial to ensure the stability of the fixing block when pushing the mounting rod to move horizontally.

[0013] Preferably, the diameter of the clamping rod is the same as the inner wall diameter of the installation slot, so as to ensure the stability of the clamping rod and the mounting slot when they are clamped together.

[0014] The beneficial effects of the utility model are:

[0015] 1. The setting of the installation mechanism, by separating the fixed plate from the four support columns, facilitates the device to enter the lane, reduces the difficulty of the device as a whole entering the lane, and at the same time, by inserting the four clamping rods into the corresponding installation grooves, and under the action of the gravity of the fixed plate and the support rod, it is conducive to automatically complete the installation between the fixed plate and the support column, and under the action of the two electric hydraulic push rods and the two connecting plates, it is conducive to the four support columns to simultaneously push the fixed plate and the support rod to move upward so that the support rod fixes the top of the lane, without adjusting the height of the four support columns separately, and at the same time, under the action of the electric push rod and the two connecting rods, it is conducive to the two installation rods to push the corresponding support plates to move simultaneously to fix the two sides of the lane, without adjusting the two support plates separately, the operation is simple, and it is more convenient to use, which effectively improves the work efficiency;

[0016] 2. When the support plate is used to fix both sides of the lane, under the action of multiple grooves, some protrusions at the fixed position of the support plate will enter the grooves, thereby increasing the contact area of ​​the support plate when fixing the lane, and at the same time increasing the friction between the contact surface of the support plate and the lane, thereby improving the support effect of the support plate on both sides of the lane.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a support device for coal mining that is easy to install includes: a fixed plate 1, the top of the fixed plate 1 is fixedly connected with support rods 2 distributed in equal rows, and the bottom of the fixed plate 1 is provided with a mounting mechanism 3; wherein the mounting mechanism 3 includes four fixed columns 301, the inner wall of the fixed column 301 is slidably connected with a support column 302, the top of the support column 302 penetrates the fixed column 301 and is provided with a mounting groove 303, the four corners of the bottom end of the fixed plate 1 are fixedly connected with a clamping rod 304, the surfaces of the two longitudinal fixed columns 301 are fixedly connected with a mounting plate 305, the inner wall of the mounting plate 305 is fixedly connected with an electric hydraulic push rod 306, the telescopic end of the electric hydraulic push rod 306 is fixedly connected with a connecting plate 307, the two ends of the connecting plate 307 are respectively fixedly connected with the surfaces of the two longitudinal support columns 302, and the top of the fixed plate 1 is provided with a mounting assembly 308. The middle part of the support rod 2 is curved in an arc shape.

[0025] When the device is used to support the tunnel, the device is first placed in the tunnel, and then the four clamping rods 304 at the bottom end of the fixed plate 1 are respectively inserted into the installation grooves 303 at the top ends of the corresponding support columns 302. At this time, under the action of the gravity of the fixed plate 1 and the support rod 2, the clamping rod 304 will automatically move downward along the inner wall of the installation groove 303 and be clamped with the installation groove 303. At this time, the installation of the fixed plate 1 and the four support columns 302 is completed. After completing this operation, the two electric hydraulic push rods 306 are started at the same time, so that the telescopic ends of the two electric hydraulic push rods 306 simultaneously push the two connecting plates 307 to drive the corresponding support columns 302 to move upward. At this time, the four support columns 302 will move upward at the same time, and push the fixed plate 1 and the support rod 2 to move upward to a suitable height, so that multiple support rods 2 support the top of the tunnel.

[0026] When the support rod 2 is pressed against the top of the tunnel, the fixing plate 1 and the support rod 2 maintain stable support under the interaction force between the top of the tunnel and the support column 302 .

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the mounting assembly 308 includes an electric push rod 3081 fixedly connected to the top of the fixed plate 1, the telescopic end of the electric push rod 3081 is fixedly connected to a circular plate 3082, two mounting rods 3084 are slidably connected to the inner wall of the fixed plate 1, the top of the mounting rod 3084 is fixedly connected to a fixed block 3085, the top of the fixed block 3085 passes through the fixed plate 1 and is hinged to a connecting rod 3083, the other ends of the two connecting rods 3083 are hinged to the surface of the circular plate 3082, and one end of the mounting rod 3084 passes through the fixed plate 1 and is fixedly connected to a support plate 3086. The top of the fixed plate 1 is provided with a slide groove 3088 matching the fixed block 3085, and the surface of the fixed block 3085 is slidably connected to the inner wall of the slide groove 3088.

[0028] When multiple support rods 2 complete supporting the top of the tunnel, start the electric push rod 3081, so that the telescopic end of the electric push rod 3081 pushes the circular plate 3082 to move downward, and drives the other ends of the two connecting rods 3083 to move downward at the same time. At this time, the angle between the two connecting rods 3083 and the horizontal plane gradually decreases, so that the two connecting rods 3083 push the corresponding installation rods 3084 through the fixed block 3085 to move at the same time and move away from each other. At this time, the two installation rods 3084 will simultaneously push the two support plates 3086 to move and support both sides of the tunnel.

[0029] like Figure 3 and Figure 4 As shown, the outer surface of the support plate 3086 is provided with grooves 3087 distributed in a rectangular array, and the opening of the groove 3087 is horn-shaped. When the support plate 3086 supports both sides of the lane, part of the protrusions at the contact part between the support plate 3086 and the lane will enter the groove 3087.

[0030] like Figure 5 As shown, the surface of the clamping rod 304 is fixedly connected to the limiting block 3089, and the inner wall of the installation groove 303 is provided with a limiting groove 30810, and the shape of the limiting groove 30810 matches the shape of the limiting block 3089. The bottom end of the limiting block 3089 is bent into an arc shape, and when the clamping rod 304 is inserted into the installation groove 303, the limiting block 3089 is aligned with the limiting groove 30810, and the limiting block 3089 enters the limiting groove 30810.

[0031] like Figure 2 and Figure 5As shown, the diameter of the clamping rod 304 is the same as the inner wall diameter of the installation groove 303. The distance between the center points of the two clamping rods 304 in the longitudinal direction is the same as the distance between the center points of the two installation grooves 303 in the longitudinal direction.

[0032] It should be noted that the electric hydraulic push rod 306 and the electric push rod 3081 in the above description are both relatively mature devices in the existing technology. The specific models can be selected according to actual needs and will not be described in detail here.

[0033] When the utility model is in use and the device is used to support the tunnel, the device is first placed in the tunnel, and then the four clamping rods 304 at the bottom end of the fixing plate 1 are respectively inserted into the mounting grooves 303 at the top ends of the corresponding support columns 302. At this time, under the action of the self-gravity of the fixing plate 1 and the support rod 2, the clamping rod 304 will automatically move downward along the inner wall of the mounting groove 303 and be clamped with the mounting groove 303, thereby completing the installation of the fixing plate 1 and the four support columns 302. After completing this operation, the two electric hydraulic push rods 306 are started at the same time, so that the telescopic ends of the two electric hydraulic push rods 306 simultaneously push the two connecting plates 307 to drive the corresponding support columns 302 to move upward. When the plurality of support rods 2 complete the support of the top of the tunnel, the electric push rod 3081 is started, so that the telescopic end of the electric push rod 3081 pushes the circular plate 3082 to move downward, and drives the other ends of the two connecting rods 3083 to move downward at the same time. At this time, the two connecting rods 3083 will push the corresponding installation rods 3084 to move at the same time through the fixed block 3085, and move away from each other, so that the two installation rods 3084 simultaneously push the two support plates 3086 to move and support both sides of the tunnel.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
