Description

Technical Field

[0001] The utility model relates to the technical field of composite support, in particular to a composite support device. Background Art

[0002] Support is a special term in pit exploration engineering. It is a support method that uses shotcrete support and any one or more of the single support methods such as anchor support, grouting, steel mesh, steel arch frame, pipe shed, etc. to improve the safety of excavation construction.

[0003] Coal mining is increasing in depth. Some mines in eastern my country have already entered the deep mining stage, with mines several thousand meters deep becoming commonplace. Deep mines are buried at great depths, resulting in high in-situ stresses in the original rock. The surrounding rock of the roadway experiences significant deformation under these high in-situ stresses. Furthermore, the increased mining intensity of modern mining equipment is increasing the frequency and intensity of rock bursts in deep mines, necessitating support structures to mitigate these effects.

[0004] During the construction of the platform composite support, it is necessary to use an anchoring structure to leave a reference point on the upper plane, and then fix the platform to be built on the reference point;

[0005] However, during use, the existing support structure can only accurately limit the vertical direction of the plane, and is not limited in the horizontal rotation direction. Multiple platforms need to be built on each other to suppress the rotation trend of the platform, which is not friendly to the construction of a single platform.

[0006] To this end, we propose a composite support device to solve the existing problems. Utility Model Content

[0007] The purpose of the utility model is to propose a composite support device in view of the problems existing in the background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a composite support device, comprising a pull rod, a spherical washer, a support plate, a main body plate, an upper pressure plate, an anchor body and a connecting rod, wherein an inner cavity is opened in the anchor body, a base is installed at the top of the inner wall of the inner cavity, a pull rod is fixed on the base, the upper pressure plate thread is arranged at the bottom end opening of the inner cavity, the main body plate is located between the upper pressure plate and the support plate, the pull rod passes through the support plate, the bottom end thread of the pull rod is provided with a nut, the nut is located at the bottom end of the support plate, and the connecting rod is connected in series with the support plate, the main body plate and the upper pressure plate.

[0009] Preferably, the upper pressure plate, the main body plate and the central axis of the spherical washer are all provided with pin holes adapted to the pull rod, and the pull rod passes through the pin holes.

[0010] Preferably, the spherical washer is located between the supporting plate and the nut, and the upper portion of the spherical washer is embedded in the supporting plate.

[0011] Preferably, a screw sleeve is welded at the center of the upper surface of the upper pressing plate;

[0012] The bottom end of the inner wall of the inner cavity is provided with a thread adapted to the outer wall of the screw sleeve, and the outer wall of the screw sleeve and the bottom end of the inner wall of the inner cavity are threadedly engaged with each other.

[0013] Preferably, the support plate, the main body plate and the upper pressure plate are all provided with positioning holes adapted to the connecting rods;

[0014] The connecting rod is connected to the positioning hole, and rotating blocks are threadedly provided at both ends of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. During use, the composite support device of the utility model can anchor the anchor body on the designated upper plane, and then install the upper pressure plate with threads below the anchor body, and place the main plate of the platform to be fixed between the upper pressure plate and the support plate. At this time, the connecting rod passes through the main plate, the upper pressure plate and the support plate, and then the nut is screwed on the bottom end of the pull rod to fix the position of the main plate of the platform. Through the design of four connecting rods, in conjunction with the support plate and the upper pressure plate, the position of the main plate can be fully defined. While accurately limiting the main plate in the vertical direction, the rotation tendency of the platform is suppressed, and it is accurately positioned. BRIEF DESCRIPTION OF THE DRAWINGS
