Description

Technical Field

[0001] This utility model belongs to the technical field of mining hydraulic props, and in particular relates to a rapid lifting control device for mining hydraulic props. Background Technology

[0002] During coal mining, in order to prevent the roof from continuously sinking or experiencing pressure changes after mining, it is usually necessary to use support equipment to support the coal mine roadway. Among them, the hydraulic prop rapid lifting control device is the core control component of the support equipment, and it is widely used, especially in the roadway advance support device, which is directly supported on the roadway ground.

[0003] Currently, most mining hydraulic prop rapid lifting control devices, when used for roadway advance support devices, usually support the hydraulic props directly on the roadway floor to support the top of the support equipment. However, once the top of the roadway collapses, the hydraulic prop lifting control device directly acting on the roadway floor will collapse downwards, causing the entire support equipment to become unstable and prone to collapse. Utility Model Content

[0004] The purpose of this invention is to provide a rapid lifting and lowering control device for mining hydraulic supports, which solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a rapid lifting control device for a mining hydraulic prop, including a hydraulic prop control component and a support base, of which two are provided and are located on both sides of the lower end of the outer wall of the hydraulic prop control component. A support member is installed through the upper surface of the support base and inserted into the mine road surface to share the gravity load borne by the upper end of the hydraulic support control member. A folding element is disposed between the support member and the support base to further support the hydraulic strut control component.

[0006] Furthermore, the support member includes two triangular prisms that pass through the upper surface of the support base, a fixing plate is provided between the two triangular prisms, multiple fitting grooves are provided on the outer walls of the two triangular prisms, triangular blocks are rotatably arranged inside the multiple fitting grooves, and magnetic blocks are provided on the inner sidewalls of the multiple triangular blocks. The upper end face of the triangular prism is provided with threaded grooves in sequence. The inner walls of the two threaded grooves are threaded with rotating heads. The lower ends of the two rotating heads are provided with connecting rods. The outer walls of the two connecting rods are fixedly fitted with magnetic rings at equal intervals.

[0007] Furthermore, the folding component includes a base plate rotatably disposed on the outer wall of the support base, and a flip plate rotatably disposed on one side wall of the fixed plate, and the base plate and the flip plate are rotatably connected.

[0008] Furthermore, the outer wall of the hydraulic support control component is rotatably provided with two first hydraulic rods; Both of the support seats are provided with rotating seats on their upper surfaces, and the two rotating seats are rotatably connected to the output ends of the corresponding first hydraulic rods.

[0009] Furthermore, two second hydraulic rods are embedded in the bottom of the support base, and the output ends of the two second hydraulic rods are connected to the fixed plate.

[0010] Furthermore, the magnetic ring and the adjacent magnetic block repel each other magnetically, and the diameter of the connecting rod is smaller than the diameter of the threaded groove.

[0011] Furthermore, the height of the flip plate is greater than the height of the base plate.

[0012] This utility model has the following beneficial effects: 1. This utility model uses a second hydraulic rod to drive the fixing plate and support to move downward, causing the support to be inserted vertically into the ground of the tunnel. During the descent, the magnetic block is subjected to the magnetic repulsion force of the magnetic ring, causing multiple triangular blocks to flip outward from multiple directions and get stuck at the lower end of the tunnel ground, forming a shape similar to tree roots, thereby supporting the hydraulic support control component and preventing it from collapsing.

[0013] 2. During the descent of the output end of the second hydraulic rod, the bottom plate and the flap will rotate. When the fixed plate is in contact with the upper end of the support seat, the bottom plate rotates and overlaps with the roadway floor. At the same time, the flap is tilted and connected between the bottom plate and the fixed plate to form a triangular support structure, thereby increasing its stability.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model is a rapid lifting control device for a mining hydraulic prop, including a hydraulic prop control component 1 and a support base 3, of which two are provided and are located on both sides of the lower end of the outer wall of the hydraulic prop control component 1. Support member 5 is installed through the upper surface of support base 3 and inserted into the mine road surface to share the gravity load borne by the upper end of hydraulic support control member 1. The folding component 7 is disposed between the support component 5 and the support base 3, and is used to further support the hydraulic support control component 1.

[0020] Furthermore, the support member 5 includes two triangular prisms 51 that are disposed through the upper end face of the support base 3. A fixing plate 58 is provided between the two triangular prisms 51. Multiple fitting grooves 56 are provided on the outer wall of each of the two triangular prisms 51. Triangular blocks 55 are rotatably disposed inside the multiple fitting grooves 56. Magnetic blocks 57 are provided on the inner side wall of the multiple triangular blocks 55. The upper surface of the triangular prism 51 is provided with threaded grooves 59 in sequence. The inner walls of the two threaded grooves 59 are threaded with rotating heads 53. The lower ends of the two rotating heads 53 are provided with connecting rods 52. The outer walls of the two connecting rods 52 are fixedly fitted with magnetic rings 54 at equal intervals. Under the action of the threaded grooves 59, the rotating heads 53 are rotated, causing the connecting rods 52 to drive the magnetic rings 54 to move downward. Due to the magnetic repulsion between the magnetic rings 54 and the magnetic blocks 57, the triangular blocks 55 in multiple directions are slightly rotated outward and move downward with the triangular prism 51, causing the multiple layers of triangular blocks 55 to be inserted into the underground of the tunnel and spread out laterally.

[0021] Furthermore, the folding component 7 includes a base plate 72 rotatably disposed on the outer wall of the support base 3, and a flip plate 71 rotatably disposed on one side wall of the fixed plate 58. The base plate 72 and the flip plate 71 are rotatably connected. By flipping the base plate 72 and the flip plate 71 simultaneously, the base plate 72 is supported on the ground, and the flip plate 71 is supported by an inclined surface, forming a triangular shape.

[0022] Furthermore, the outer wall of the hydraulic support control component 1 is rotatably provided with two first hydraulic rods 2; Both support seats 3 are provided with rotating seats 4 on their upper surfaces. The two rotating seats 4 are rotatably connected to the output ends of the corresponding first hydraulic rods 2. Since the rotating seats 4 are provided on the upper surface of the support seats 3, a triangular shape can be formed by using the first hydraulic rods 2 as the hypotenuse, thereby connecting and supporting the hydraulic support control component 1 and the support seats 3.

[0023] Furthermore, two second hydraulic rods 6 are embedded in the bottom of the support base 3. The output ends of the two second hydraulic rods 6 are connected to the fixed plate 58. The fixed plate 58 can be moved down by the second hydraulic rods 6, thereby further pressing down the triangular prism 51 and inserting it into the mine roadway surface.

[0024] Furthermore, the magnetic ring 54 and the adjacent magnetic block 57 are magnetically repelled, and the diameter of the connecting rod 52 is smaller than the diameter of the threaded groove 59.

[0025] Furthermore, the height of the flip plate 71 is greater than the height of the base plate 72.

[0026] A specific application of this embodiment is as follows: In use, multiple hydraulic prop control components 1 are first placed on both sides of the support equipment and lifted and supported. Then, the first hydraulic rod 2 is used to press down the support seats 3 on both sides of the hydraulic prop control component 1, so that the support seats 3 are in contact with the roadway ground. Then, the rotating head 53 is manually rotated, so that the connecting rod 52 drives the magnetic ring 54 to move down. Due to the magnetic repulsion between the magnetic ring 54 and the magnetic block 57, multiple triangular blocks 55 are simultaneously rotated outward by five to ten degrees. The second hydraulic rod 6 is used to drive the fixing plate 58 to press down. Under the action of the fixing plate 58, the two triangular pillars 51 are moved down simultaneously. During the downward movement, under the action of the roadway ground soil, the triangular blocks 55 will further unfold and insert into the roadway ground soil, so that the lower end of the support component 5 is inserted into the roadway soil like a tree root. This allows the hydraulic prop control component 1 to be better supported when the roadway top collapses, preventing the hydraulic prop control component 1 from sinking.

[0027] It should be noted that during the descent of the fixed plate 58, the base plate 72 and the flip plate 71 are rotated, causing the base plate 72 and the flip plate 71 to fit together. The flip plate 71 is inclined and supported between the base plate 72 and the fixed plate 58, forming a stable triangular structure, which can better support the hydraulic support control component 1.
