Description

Technical Field

[0001] The utility model belongs to the field of coal mine production, in particular to a signboard fixing display rack used in an underground chamber of a coal mine. Background Art

[0002] A chamber is a horizontal tunnel with a large cross section and a short length that does not directly lead to the surface exit. Its function is to install various equipment and machines, store materials and tools, or for other special purposes, such as machine repair rooms, explosives warehouses, rest rooms, etc.

[0003] The underground chambers of coal mines need to be equipped with signboards according to production requirements, and the monorail crane driver shift system, monorail crane locomotive operation management system and other systems are displayed and informed. In the mine standardization construction work, each unit optimizes and transforms its own professional system facilities and equipment. The monorail crane and chamber need to hang a large number of signboards, which must meet the effect of beauty and neatness.

[0004] The hanging of the signboards in the underground chambers of coal mines mostly adopts steel strands and iron wire hanging or single hanging with expansion wires, which has the following difficulties: first, there are many signboards, and the steel strands are pulled for hanging, so the bottom of the signboards is not neat and straight, and the overall effect of the signboards is not beautiful, which does not meet the standardization requirements; second, the acrylic plate must be fixed by screw drilling, which has high requirements on the flatness of the wall surface, and the site does not meet the hanging requirements; third, the traditional hanging adopts steel strands, iron wires, cable ties, etc., which are easily corroded and damaged by the harsh conditions underground; fourth, the signboards are often hung on the cable side, and the signboards after hanging are not beautiful and do not meet the requirements due to the influence of the cables; therefore, the existing technology has the problems of uneven overall signboards after hanging, uneven hanging and easy to fall off, and there is also the problem of interference between the cable and the signboard hanging.

[0008] The fixed base of the signboard is fixed on the side wall of the underground chamber tunnel;

[0009] An adjusting pipe, one end of which is fixedly connected to the fixing base of the signboard, and the other end of which extends into the chamber tunnel;

[0010] The adjusting rod has an inner end extending into the adjusting tube and being tightened by a fixing screw passing through the adjusting tube, and an outer end extending out of the adjusting tube; the adjusting tube is used to adjust the length of the adjusting rod extending out of the adjusting tube according to the inclination of the side wall of the laneway;

[0011] The upper baffle of the signboard is horizontally arranged, and its two ends are respectively fixedly connected to the outer ends of the two adjusting rods located on the upper side; the lower baffle of the signboard is horizontally arranged, and its two ends are respectively fixedly connected to the outer ends of the two adjusting rods located on the lower side;

[0012] The upper side of the signboard fence is fixedly connected to the upper baffle bar of the signboard, and a predetermined distance is formed to form an upper signboard gap. The lower side of the signboard fence is fixedly connected to the lower baffle bar of the signboard, and a predetermined distance is formed to form a lower signboard gap. The upper signboard gap and the lower signboard gap are respectively used for the upper and lower ends of the signboard to extend into, thereby vertically fixing the signboard on the side wall of the chamber tunnel.

[0013] Furthermore, the card board fence includes an upper guard plate and a lower guard plate, both of which are "L"-shaped. The lower side of the horizontal section of the upper guard plate is fixedly connected to the upper side of the stop bar on the card board, and its vertical section extends downward and forms an upper card board gap with the stop bar on the card board. The upper side of the horizontal section of the lower guard plate is fixedly connected to the lower side of the lower stop bar of the card board, and its vertical section extends upward and forms a lower card board gap with the lower stop bar of the card board.

[0014] Furthermore, the sign board fence also includes: a left blocking plate, which is vertically arranged, and its two ends are respectively fixedly connected to the left ends of the upper blocking rod of the sign board and the lower blocking rod of the sign board, so as to limit the left side of the sign board.

[0015] Furthermore, the sign board fence also includes: a right blocking plate, which is vertically arranged, and its two ends are respectively clamped with the right ends of the upper blocking rod and the lower blocking rod of the sign board, so as to limit the right side of the sign board.

[0016] The beneficial effects of the utility model are:

[0017] After installation, the utility model can arrange the cable against the side wall of the tunnel without affecting the hanging of the tunnel cable, and effectively solves the problem of interference between the hanging of the cable and the signboard; the utility model clamps the signboard by setting the gap between the upper signboard and the lower signboard, so that the signboard is fixed on the side wall of the tunnel, and solves the problem of high flatness requirements for commonly used signboards during installation, because commonly used signboards are basically flat, and the flatness of the side wall of the tunnel cannot meet the requirements during installation. Therefore, the signboard can be fixed by clamping, and the signboard can be fixed on the side wall of the tunnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1

[0032] A mine in Hancheng encountered the following difficulties during the installation of chamber signboards. First, there were many signboards, and the steel strands were pulled for hanging. The bottom of the signboards was not neat and straight, and the overall effect of the signboards was not beautiful and did not meet the standardization requirements. Second, the acrylic panels must be fixed by drilling holes with screws, which has high requirements for the flatness of the wall and does not meet the hanging requirements on site. Third, traditional hanging uses steel strands, iron wires, cable ties, etc., which are easily corroded and damaged by the harsh conditions underground. Fourth, the signboards are often hung on the cable side, and are affected by the cables. The signboards after hanging are not beautiful and do not meet the requirements. Therefore, the existing technology has the problems of uneven overall signboards after hanging, uneven hanging, and easy to fall off. In addition, there is also the problem of interference between the cable and the signboard hanging.

[0033] By utilizing the utility model for improvement, the signboard fence is made of angle iron, the signboard fixing base 12 is made of steel plate, the adjusting rod 14 is made of steel bar, and the adjusting tube 13 is made of steel tube, thereby forming an upper signboard gap of 8 mm and a lower signboard gap of 8 mm, so that the signboard can be inserted from the right side and fixed reliably without shaking, thus solving the influence caused by the uneven wall of the laneway.
