Description
Technical Field
The utility model relates to an equipment technical field under the ore deposit, concretely relates to a base that is used for support withdrawal device under ore deposit.
Background
The hydraulic support is the most common roadway support structure in the underground coal mine, and plays a role in maintaining the stability of the roadway coal wall due to the characteristics of quick installation and high stability. However, hydraulic jacks are too bulky and therefore encounter great difficulty in withdrawing them. The traditional hydraulic support withdrawing method is to use a traction device to forcibly drag the hydraulic support away, and a folding hydraulic support withdrawing forklift is also used for transportation. The transportation means have the characteristics that the balance of the hydraulic support in the carrying process cannot be guaranteed, the hydraulic support has the risk of toppling, and great threat is caused to the personnel of operators on site. The hydraulic support may also have a problem of slipping down the slope, especially in a roadway with a slope.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the utility model provides a base for on ore deposit lower carriage withdrawal device to solve current ore deposit lower carriage and easily empty, easily swift current slope, there is the problem of certain safety risk.
In order to solve the above problem, the utility model provides a following technical scheme:
a base used for a mine lower support withdrawing device comprises more than two functional tables which have the same structure and are connected end to end; the front side and the rear side of each functional table are respectively provided with a connecting clamping piece which are matched with each other, and two adjacent functional tables are detachably connected through the connecting clamping pieces; the single functional table comprises a bottom plate and limiting plates arranged on the left side and the right side of the top end face of the bottom plate; the bottom plate on each functional table is in an inclined structure, and the end sides of the bottom plates on two adjacent functional tables have height difference.
Preferably, the height of the top side of the limiting plate is greater than the plate surface height of the bottom plate.
Preferably, the two limit plates on the function table are symmetrically provided with hydraulic telescopic supports.
Preferably, pulleys are further arranged on the two limiting plates on the function table.
Preferably, the height difference of the front section and the rear section of the upper bottom plate 3 of the single functional table is between 5 and 15 cm.
The utility model discloses beneficial effect:
the utility model discloses a colliery is base of hydraulic support withdrawal platform in pit, with the bottom plate design on the base for inclined plane structure, after hydraulic support's withdrawal platform is constituteed to function platform end to end more than two, formed a plurality of stair structures that prevent swift current behind the hydraulic support between the bottom plate of two adjacent bases to prevent that hydraulic support from withdrawing in the tunnel of slope section when the operation, the problem of swift current slope appears in the hydraulic support. Meanwhile, the hydraulic telescopic supports arranged on the function table can firmly fix the function table on the ground, so that the base plate and the ground are prevented from sliding mutually, and the safety of withdrawal operation is further influenced. Moreover, the rope of the tractor can be connected with the hydraulic support from the two sides of the bottom plate through the pulleys on the two sides, and the hydraulic support is evenly stressed on the two sides, so that the problem that the traditional tractor is toppled due to uneven stress when the hydraulic support is dragged is solved.
Drawings
Fig. 1 is a schematic structural view of the utility model in the present embodiment;
description of reference numerals: 1. the multifunctional support comprises a functional table 2, a limiting plate 3, a bottom plate 4, a pulley 5 and a hydraulic telescopic support.
Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
example (b):
referring to fig. 1, the present embodiment provides a base for a mine lower rack retracting device, which includes more than two functional tables 1 with the same structure and connected end to end; the front side and the rear side of each functional table 1 are respectively provided with a connecting clamping piece which are matched with each other, and two adjacent functional tables 1 are detachably connected through the connecting clamping pieces; the single functional table 1 comprises a bottom plate 3 and limiting plates 2 arranged on the left side and the right side of the top end face of the bottom plate 3; the bottom plate 3 on each function table 1 is of an inclined structure, and the end sides of the bottom plates 3 on two adjacent function tables 1 have a height difference.
The height of the upper top side of the limit plate 2 is greater than the plate surface height of the bottom plate 3.
Hydraulic telescopic supports 5 are symmetrically arranged on the two limit plates 2 on the functional table 1. The piston rod of the hydraulic telescopic support 5 extends out and props against the top of the roadway to firmly fix the bottom plate 1 on the ground. In practical application, the hydraulic telescopic supports 5 are not required to be arranged on each bottom plate 1, and the hydraulic telescopic supports can be arranged on the bases 1 at the front part, the middle part and the tail part of the mine lower support withdrawing platform.
Pulleys 4 are also arranged on the two limiting plates 2 on the functional table 1. When the traction machine is operated specifically, the rope of the traction machine is connected with the hydraulic support from two sides of the bottom plate 1 through the pulleys 4 on two sides, the hydraulic support is evenly stressed on two sides, and the problem that the traditional traction machine is toppled due to uneven stress when the hydraulic support is dragged is solved.
The size of the height difference of the front section and the rear section of the upper bottom plate 3 of the single function table is between 5 and 15 cm. The step between two adjacent bottom plates 1 is ensured to be high enough to block the hydraulic support. Meanwhile, the tail of the hydraulic support is prevented from freely falling when the hydraulic support slides through the steps due to the fact that the steps are too high, and therefore the hydraulic support is broken.
