Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mining, and particularly relates to an impact ground pressure mine supporting material limiting device. BACKGROUND

[0002] When supporting materials are stored in a mine, the supporting materials must be fixed and limited to prevent the scattered equipment and materials from flying up and injuring people again when impact occurs, resulting in an accident. The traditional method is to fix the supporting materials by a rope. Although this method can fix the supporting materials, it is inconvenient to take the supporting materials. At present, a supporting material support frame is usually used to fix and limit the supporting materials by limiting and fixing an anchor rod and a supporting plate. Compared with the traditional method, the supporting material support frame can effectively fix and limit the supporting materials and is convenient to take the supporting materials.

[0003] However, when the supporting material support frame positions the supporting plate, the threaded hole of the supporting plate needs to be inserted into the inside of the positioning rod to position the supporting plate. Although the threaded hole of the supporting plate can be effectively fixed, the horizontal degree of the supporting plate needs to be maintained when the supporting plate is stored and taken, and the overall operation is inconvenient. If the diameter of the positioning rod is smaller than that of the threaded hole of the supporting plate, the supporting plate can be conveniently taken, but the supporting plate cannot be effectively fixed.

[0052] Embodiment 2

[0053] Reference Figures 1-9 This embodiment is based on the first embodiment:

[0054] When the pallets 1 need to be taken out, the distance of pulling the handle 107e-2 is controlled according to the number of the pallets 1 that need to be taken out. If only a few pallets 1 need to be taken out, the handle 107e-2 is pulled to make the slide rod 107a leak out a display strip 107d, at this time, only the topmost push block 107c of the slide rod 107a is located in the inside of the corresponding rotating disc 106a and is dislocated with the convex strip 106b in the inside of the corresponding rotating disc 106a, then the handle 107e-2 is reversed to only shrink the uppermost pressing plate 106e-2 of the outer sleeve 102 to be unlocked, so that the pallets 1 are taken out. If all the pallets 1 need to be taken out, the slide rod 107a is only pulled up to the last display strip 107d, then the handle 107e-2 is reversed, thus only different positions are pulled according to the needs, and the corresponding pressing plates 106e-2 are unlocked from top to bottom.

[0055] In summary, according to the number of the pallets 1 that need to be taken out, the corresponding pressing plates 106e-2 are unlocked, which not only can take out the pallets 1, but also can fix the pallets 1 that do not need to be taken out. At the same time, the pallets 1 are unlocked and taken out from top to bottom, which can avoid the situation that the bottom pallets 1 are disordered when only a few pallets 1 are taken out, so that the position of the lower pallets 1 is not affected when the upper pallets 1 are taken out, and the pallets 1 can be stored neatly without the need for secondary arrangement.

[0056] Furthermore, according to the number of the pallets 1 that need to be taken out, the corresponding pressing plates 106e-2 are unlocked, which can only cause the shaking of the unlocked pallets 1 when the pallets 1 are taken out, which not only can effectively reduce the risk of casualties caused by dangerous accidents, but also can reduce the damage of the pallets 1 and the loss.

[0062] The position of the side plate 201 is located at the roadway side, so that the stability of the whole device can be improved, and through the design that the two ends of the rope 304 are connected with the cross bars 204, not only the strength of the whole device can be improved, but also the rope 304 can limit the top rod 107e-1 through the groove 107e-3, so that the rotation of the top rod 107e-1 can be avoided, and the stability of the fixed support plate 1 can be improved.

[0063] When the support plate 1 needs to be taken out, the rope 304 is unlocked by rotating the knob pressing rod 303, and then the handle 107e-2 is pulled and rotated according to the needs.

[0064] In summary, through the rope 304, not only the strength of the whole device can be improved, but also the top rod 107e-1 can be limited, so that the rotation of the top rod 107e-1 can be avoided, and the stability of the fixed support plate 1 can be improved.
