Description
Technical Field
The utility model belongs to the technical field of mining transportation equipment, concretely relates to movable support.
Background
At present, the underground coal mine support is transported to a working face by a single-rail hoisting whole-frame transportation. The existing supports are all in a fixed standing state, namely the overall height of the supports is high, the supports are transported in the standing state, and the transportation mode enables the roadway to be high in tunneling height, large in tunneling amount, long in tunneling period and high in labor intensity.
Disclosure of Invention
In order to overcome the shortcoming of the prior art, the utility model provides a movable support changes the supporting platform of support into swing joint, overturns supporting platform through the jack, when the transportation, falls to the minimum with the whole height of support, consequently, has reduced the height that the tunnel was tunneled, has reduced the volume of drivage, has reduced intensity of labour promptly and has also improved work efficiency.
The utility model discloses a realize through following technical scheme: a movable support comprises a base, a pushing frame and a supporting platform, wherein a guide rail is arranged on the base, the pushing frame is arranged in the guide rail, one end of the base is hinged with a pushing jack, and one end, far away from the hinged point of the pushing jack and the base, of the pushing jack is hinged with the pushing frame; the whole supporting platform is L-shaped, and the bending part of the supporting platform is hinged with the pushing frame; the support platform is characterized by further comprising a turnover jack, one end of the turnover jack is hinged to the top of the longer side of the support platform, the other end of the turnover jack is hinged to the pushing frame, and hollow structures for the turnover jack to rotate are arranged on the pushing frame and the base.
Furthermore, the pushing jack is arranged on the central line position of the base, a rectangular opening is formed in the end portion of the base, the jack hinge seat is installed at the rectangular opening of the base, and the pushing jack is hinged to the jack hinge seat.
Furthermore, the base is symmetrically provided with guide rails relative to the pushing jack, and hollow structures penetrating through the base are arranged in the guide rails.
Further, the longer side of the pushing jack and the supporting platform is located on the same side of the base.
The utility model has the advantages that: this application changes the supporting platform of support into swing joint, overturns supporting platform through the jack, when the transportation, falls to the minimum with the whole height of support, then the whole transportation of lifting by crane of rethread monorail crane, consequently, has reduced the height that the tunnel was tunneled, has reduced the volume of drivage, has reduced intensity of labour promptly and has also improved work efficiency.

Detailed Description
The invention will be further explained below with reference to the drawings and examples.
As shown in fig. 1 to 4, a movable support includes a base 1, a pushing frame 3 and a supporting platform 5, wherein one end of the base 1 is hinged with a pushing jack 2, the pushing jack 2 is arranged on a central line of the base 1, and one end of the pushing jack 2 away from a hinge point of the pushing jack 2 and the base 1 is hinged with the pushing frame 3; the base 1 is symmetrically provided with guide rails 1-1 about the pushing jack 2, the pushing frame 3 is arranged in the guide rails 1-1, the whole supporting platform 5 is L-shaped, the bending part of the supporting platform 5 is hinged with the pushing frame 3, the pushing frame 3 is provided with a hinged support, and the supporting platform 5 is hinged with the hinged support; the folding and unfolding device further comprises a folding and unfolding jack 4, one end of the folding and unfolding jack 4 is hinged with the top of the longer side of the supporting platform 5, the other end of the folding and unfolding jack 4 is hinged with the pushing frame 3, a hollow structure is arranged on the pushing frame 3, and a hollow structure penetrating through the base 1 is arranged in the guide rail 1-1. The hollow structure of the pushing frame 3 and the hollow structure of the guide rail 1-1 are designed for the turning jack 4 to rotate. The longer sides of the pushing jack 2 and the supporting platform 5 are positioned on the same side of the base 1. As shown in fig. 4, in the structure of the present invention, the pushing jack 2 may be provided at the other end of the base 1, that is, the pushing jack 2 and the longer side of the supporting platform 5 may be located at both sides of the base 1.
Preferably, the end of the base 1 is provided with a rectangular opening, the jack hinge seat 6 is installed at the rectangular opening of the base 1, and the pushing jack 2 is hinged to the jack hinge seat 6.
This application changes the supporting platform of support into swing joint, overturns supporting platform through the jack, when the transportation, falls to the minimum with the whole height of support, then the whole transportation of lifting by crane of rethread monorail crane, consequently, has reduced the height that the tunnel was tunneled, has reduced the volume of drivage, has reduced intensity of labour promptly and has also improved work efficiency. The pushing jack is used for adjusting the whole gravity center of the support when the supporting platform 5 is in different states, so that the influence on transportation caused by gravity unbalance is avoided.
