The folding advanced support solves the problems of high work intensity and low efficiency when the existing support equipment is used for manual operation with the advancement of the working face in the roadway.

Description

Folding type forepoling

Technical Field

The invention belongs to the technical field of coal mine supporting equipment, and particularly relates to a folding type advance support.

Background

Support equipment is needed to be used for supporting the top of the roadway under the coal mine, and the width of the support equipment is generally slightly smaller than that of the mine tunnel.

Roadway advance support equipment or lagging support equipment mostly adopt a one-beam four-column support mode, and need to move forward along with the propulsion of a working face, but the existing support equipment is integrally fixed together, so that the movement can only be completed in a manual carrying mode, and the support equipment is conveyed to a specified position for continuous support, and the operation mode is high in working strength and low in efficiency.

Disclosure of Invention

The invention aims to provide a folding type forepoling, which solves the problems of high working strength and low efficiency when the existing supporting equipment is used for carrying out manual operation along with the advance of a working surface in a roadway.

In order to solve the problems, the invention discloses a folding type forepoling which comprises a middle beam, wherein two ends of the middle beam are provided with edge beams in a folding manner, and the lower sides of the two edge beams are provided with at least one telescopic upright post.

The technical scheme of the invention also has the following characteristics:

furthermore, one end of each of the two side beams is hinged to the middle beam through a pin shaft, a connecting seat is arranged on the side portion of the middle beam, two reciprocating telescopic mechanisms are hinged to the connecting seat, and the driving ends of the two reciprocating telescopic mechanisms are hinged to the corresponding side beams.

Further, the lower side of each edge beam is provided with two upright posts.

Further, a pair of insertion holes is provided on the lower side of the center sill.

Further, the reciprocating telescopic mechanism is an oil cylinder.

Compared with the prior art, the folding type forepoling disclosed by the invention has the following advantages: (1) according to the folding type forepoling, the boundary beams on the two sides can rotate by taking the two ends of the middle beam as base points, and can be folded towards the middle beam during movement, so that the overall size of the bracket is reduced, and the bracket is convenient to carry in a roadway with limited width; (2) according to the folding type forepoling, the height of the whole forepoling can be reduced through the expansion and contraction of the upright posts, the folding type forepoling is convenient to prevent from moving on a forklift, and a roadway cannot be collided during moving; (3) the folding type forepoling has the advantages of simple integral structure, low manufacturing cost and good popularization and application prospect.

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention and not to limit the invention. In the drawings:

FIG. 1 is a schematic view of a foldable forepoling of the present invention;

fig. 2 is a top view of a folding lead frame of the present invention.

In the figure: 1. the device comprises a middle beam, 2 reciprocating telescopic mechanisms, 3 connecting seats, 4 pin shafts, 5 side beams, 6 stand columns and 7 jacks.

Detailed Description

The following embodiments are described in detail with reference to the accompanying drawings, so that how to implement the technical features of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.

As shown in fig. 1 and 2, the folding type forepoling of the invention comprises a middle beam 1, wherein both ends of the middle beam 1 can be provided with edge beams 5 in a folding way, and the lower sides of the two edge beams 5 are provided with at least one telescopic upright post 6.

When the folding type forepoling is used for supporting under a normal condition, the two side beams 5 are in an open state, and the upright post 6 (the upright post is a telescopic upright post, and the telescopic action is completed through a hydraulic cylinder arranged at the bottom of the telescopic upright post) is in an extended state. With the advance of the working face, when the foldable forepoling bracket needs to move, the upright post 6 is contracted to reduce the overall height, then the reciprocating telescoping mechanism 2 is contracted to fold the two side beams 5 towards the middle beam 1, the volume of the foldable forepoling bracket is reduced, and finally a forklift is inserted into the insertion hole 7 to move the foldable forepoling bracket to the designated position. After the two side beams are moved to the designated positions, the two side beams 5 are in the open state again, and the upright post 6 is in the extending state, so that the support can be completed.

As shown in fig. 1, in the folding type forepoling of the present invention, one end of each of two side beams 5 is hinged to a middle beam 1 through a pin 4, a connecting seat 3 is provided at a side portion of the middle beam 1, two reciprocating telescopic mechanisms 2 are hinged to the connecting seat 3, and driving ends of the two reciprocating telescopic mechanisms 2 are hinged to the corresponding side beams 5.

The two reciprocating telescopic mechanisms 2 are sleeved on a pin shaft in the connecting seat 3 to realize hinged assembly; the driving ends of the two reciprocating telescopic mechanisms 2 are arranged on a pin shaft in the middle beam 1 to realize hinged assembly, and the beams 5 at the two sides are folded towards the middle beam 1 in a hinged mode.

As shown in fig. 1, in the foldable forepoling of the present invention, two posts 6 are provided at the lower side of each side sill 5, and the support of both side sills 5 and center sill 1 can be stably accomplished.

As shown in fig. 1, in a folding type fore carriage of the present invention, a pair of insertion holes 7 are provided on the lower side of a center sill 1, and a plug of a forklift can be inserted into the insertion holes 7 to perform the movement of the folding type fore carriage of the present invention.

As shown in fig. 1, in a folding type advance frame of the present invention, the reciprocating telescoping mechanism 2 is preferably a cylinder, and it is possible to ensure output of a sufficiently large driving force.

Therefore, compared with the prior art, the folding type forepoling of the invention has the following advantages: (1) according to the folding type forepoling, the boundary beams on the two sides can rotate by taking the two ends of the middle beam as base points, and can be folded towards the middle beam during movement, so that the overall size of the bracket is reduced, and the bracket is convenient to carry in a roadway with limited width; (2) according to the folding type forepoling, the height of the whole forepoling can be reduced through the expansion and contraction of the upright posts, the folding type forepoling is convenient to place on a forklift to move, and a roadway cannot be collided during moving; (3) the folding type forepoling has the advantages of simple integral structure, low manufacturing cost and good popularization and application prospect.
