[0002] At present, the height of coal mine tunnels is generally above 3m, and the width is generally above 4m. When the existing anchor bolt and cable support equipment, such as the four-arm anchor drilling vehicle, performs anchor bolt or cable support operations on both sides of the tunnel, its ceiling adopts an integral structure, that is, the extension plate is located in the hollow cavity of the roof. When the integral structure is used to protect the top, the extension plate is easy to get stuck when it is extended from the roof, and the spacing between the telescopic tracks cannot be adjusted, and the flexibility is poor. In this way, when the telescopic guard plate needs to be used when coal slag falls in the tunnel, it is easy to get stuck and cause danger. In addition, the existing ceiling does not have a separate lifting function, which leads to insufficient working height for operators and poses a safety hazard.

[0003] Therefore, based on the structural and functional defects and deficiencies of the ceiling used on the working platform in the existing anchor rod and cable support equipment, it is urgent to design a retractable ceiling for the working platform with flexible sliding tracks, smooth horizontal telescopic movements, and adjustable lifting and lowering, so as to solve the safety hazards caused by operators during the ceiling protection process.

DETAILED DESCRIPTION

[0026] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0027] The telescopic roof for the working platform of this embodiment can be used on the working platform of any anchor drilling vehicle, and of course, can also be used on other equipment that requires top protection, and has the advantages of simple installation and disassembly, flexible adjustment, large protection range, safety and reliability. Specific embodiments are as follows.

[0028] See attached Figures 1 to 4As shown, this embodiment is used for the telescopic ceiling of the anchor drilling vehicle working platform, including a top plate 1, a telescopic plate 2 and a telescopic oil cylinder 3. The telescopic plate 2 is movably fixed under the top plate 1 through a pressure plate mechanism 4.

[0029] Combined with Figure 5 As shown, the pressing plate mechanism 4 in this embodiment includes a bending pressing plate 41 , an adjusting gasket 42 and a wear-resistant copper plate 43 .

[0030] The first bending portion 411, the adjustment gasket 42 and the wear-resistant copper plate 43 of the bending pressure plate 41 are fixed to the bottom of the top plate 1 by bolts in sequence, and a gap is formed between the second bending portion 412 arranged in a staggered manner with the first bending portion 411 and the wear-resistant copper plate 43, forming a sliding track 40 for the installation and horizontal extension of the telescopic plate 2. Preferably, two sets of the bending pressure plates 41 facing each other are arranged at the bottom of the top plate 1, which can better ensure the smooth extension and retraction of the telescopic plate 2.

[0031] One end of the telescopic oil cylinder 3 is connected to the telescopic plate 1 , and the other end is connected to the top plate 1 . The telescopic plate 2 is horizontally telescoped along the sliding track 40 under the action of the telescopic oil cylinder 3 .

[0032] In this embodiment, the adjusting gasket 42 can be used to adjust the thickness of the sliding track 40 to adapt to different telescopic plate thicknesses, effectively avoiding the jamming phenomenon when the telescopic plate is extended or retracted. The adjusting gasket 42 can adopt gasket specifications of different thicknesses, or a plurality of gaskets can be stacked to adjust the thickness of the sliding track 40.

[0033] The wear-resistant copper plate 43 can prevent the telescopic plate 2 from directly rubbing against the bottom of the top plate 1 when telescopic, thereby increasing the service life of the telescopic ceiling. Of course, the pressing plate mechanism can also directly connect the bending pressing plate 41 to the bottom of the top plate to achieve the fixing and telescoping of the telescopic plate 2.

[0034] In this embodiment, one end of the bending plate 41 away from the second bending portion 412 is provided with a positioning protrusion 413 extending toward the wear-resistant copper plate 43, which plays a role in positioning the bending plate and facilitates installation.

[0035] In this embodiment, the distance between the two bending pressing plates 41 is set according to the width of the telescopic plate 2 to meet the use of different telescopic plates.

[0036] In a more preferred embodiment, the telescopic ceiling further comprises a lifting mechanism 5 arranged at the bottom of the top plate 1. The lifting mechanism 5 comprises a lifting cylinder 51, a vertical plate 52 and a lifting cylinder 53.

[0037] The top of the lifting cylinder 51 is fixedly connected to the top plate 1, the side of the lifting cylinder 51 is slidably connected to the vertical plate 52, one end of the lifting cylinder 53 is connected to the upper end of the lifting cylinder 51, and the other end is connected to the lower end of the vertical plate 52. The top plate 1 is adjusted up and down under the action of the lifting cylinder 53. Preferably, the lifting cylinder 53 is arranged inside the lifting cylinder 51.

[0038] In this embodiment, an operating valve group 6 is provided on the vertical plate 52 for controlling the up and down adjustment of the top plate 1 and the horizontal extension and retraction of the retractable plate 2 .

[0039] In this embodiment, two parallel lifting mechanisms 5 are provided on one side of the bottom of the top plate 1, and two telescopic plates 2 are respectively extended outward horizontally on the other side of the bottom of the top plate 1 to ensure the reliability of the top plate lifting and to expand the protection range of the ceiling. Figure 6 shown.

[0040] The utility model retractable ceiling changes the existing integral ceiling structure through the split sliding track structure, which is more conducive to the installation and disassembly of the telescopic plate. The combined use of the pressure plate mechanism can flexibly adjust the thickness of the sliding track, that is, it can be used according to the actual situation to deal with different telescopic plates, ensure that the telescopic plate is not stuck, improve the safety and reliability of the telescopic ceiling, and improve the wear resistance of the ceiling and extend the service life. The setting of the lifting mechanism can also meet the free lifting of the top plate, so that the operator has a larger operating space and safer work.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which are all within the protection scope of the present invention.
