The support frame has the advantages that the support frame can adapt to the support of the sheds with different sizes, has strong applicability, can be reused, and reduces the construction cost.

Description

Support frame for shed

Technical Field

The utility model relates to the technical field of coal mine mining, in particular to a shed support frame.

Background

In mine tunneling, the construction process of the frame shed is a main supporting process. In blasting, blasting and shed collapse are phenomena which need to be actively prevented in shed construction.

At present, in order to prevent blasting from collapsing the shed, wooden struts are generally adopted to reinforce the shed which is constructed among the sheds. However, the wooden support is of a fixed size under the condition of advanced processing, but the size of the wooden support is changed in the tunneling process, so that the wooden support cannot be fully suitable for the field condition, the wooden support after being stressed is difficult to reuse, and the construction cost is increased.

Disclosure of Invention

The utility model aims to solve the technical problem of adapting to different-sized sheds and reduce the construction cost.

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model provides a frame canopy support frame, includes sleeve, first telescopic link, second telescopic link and joint spare, sleeve inner wall both ends are equipped with the internal thread that the screw thread direction is opposite, sleeve one end threaded connection first telescopic link, the second telescopic link is connected to the other end, telescopic one end is kept away from to first telescopic link and second telescopic link all is provided with the joint spare, still be equipped with a plurality of lever holes on the sleeve outer wall.

The two clamping pieces are clamped on the shed, a lever is inserted into the lever hole, and the lever is rotated to drive the sleeve to rotate, so that the first telescopic rod and the second telescopic rod are expanded on the sleeve, and the shed is supported; the support frame can adapt to the support of the frame shed with different sizes, has strong applicability, can be repeatedly utilized, and reduces the construction cost.

Preferably, the clamping piece is a U-shaped clamping piece.

Preferably, the inner wall of the clamping piece is provided with anti-skid protruding points.

Preferably, the clamping piece is welded on the first telescopic rod and the second telescopic rod.

Compared with the prior art, the utility model has the beneficial effects that:

Detailed Description

In order to facilitate the understanding of the technical scheme of the present utility model by those skilled in the art, the technical scheme of the present utility model will be further described with reference to the accompanying drawings.

In this application, unless specifically stated and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; the device can be mechanically connected, electrically connected and communicated; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

In this application, the terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated unless otherwise explicitly specified and defined. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1, this embodiment discloses a canopy support frame, including sleeve 1, first telescopic link 2, second telescopic link 3 and joint spare 4, sleeve 1 inner wall both ends are equipped with the internal thread that the screw thread direction is opposite, sleeve 1 one end threaded connection first telescopic link 2, the second telescopic link 3 is connected to the other end, the joint spare 4 has all been welded to the one end that sleeve 1 was kept away from to first telescopic link 2 and second telescopic link 3, in this embodiment, joint spare 4 is U type joint spare for the joint is on canopy 5, still be equipped with a plurality of lever holes 11 on the sleeve 1 outer wall.

Specifically, the two clamping pieces 4 are clamped on the shed 5, a lever is inserted into the lever hole 11, and the lever is rotated to drive the sleeve 1 to rotate, so that the first telescopic rod 2 and the second telescopic rod 3 are expanded on the sleeve 1, and the shed 5 is supported; the support frame can adapt to the support of the frame shed 5 with different sizes, has strong applicability, can be repeatedly utilized, and reduces the construction cost.

Further, anti-skidding protruding points are arranged on the inner wall of the clamping piece 4, friction force between the clamping piece 4 and the frame shed 5 is improved, and the clamping piece 4 is prevented from sliding on the frame shed 5.

The working principle of the embodiment is as follows:

when in installation: two clamping pieces 4 are clamped on the shed 5, a lever is inserted into the lever hole 11, and the sleeve 1 is driven to rotate by rotating the lever, so that the first telescopic rod 2 and the second telescopic rod 3 are expanded on the sleeve 1, and the shed 5 is supported.

When the disassembly is carried out: the lever is inserted into the lever hole 11, the rotating lever drives the sleeve 1 to reversely rotate, the first telescopic rod 2 and the second telescopic rod 3 shrink on the sleeve 1, and the clamping piece 4 is separated from the shed 5.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

The above-described embodiments merely represent embodiments of the utility model, the scope of the utility model is not limited to the above-described embodiments, and it is obvious to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
