Description

Technical Field

[0001] The utility model belongs to the technical field of transportation devices, in particular to a coal mine hydraulic support transportation device. Background Art

[0002] With the improvement of mining equipment and technology, most coal mining faces in coal mines have realized comprehensive mechanical mining, such as using coal mining machines to cut coal, scraper conveyors to transport, hydraulic supports to support the roof, etc. According to the thickness and slope of the coal seam at the working face, different hydraulic supports are selected for different coal seam working faces; hydraulic supports are large-scale equipment. Taking ZQY3400 / 15 / 35 shielded hydraulic supports and ZQY2800 / 09 / 24 shielded hydraulic supports as examples, the support width of ZQY2800 / 09 / 24 shielded hydraulic supports is 1430mm~1600mm, the length is 5200mm~5600mm, and the weight is 9.1t; the support width of ZQY3400 / 15 / 35 shielded hydraulic supports is 1430mm~1600mm, the length is 5000mm~5400mm, and the weight is 12.9t. It can be seen that the hydraulic support is not only large in size, but also very heavy. Due to the limited space and technical equipment underground in the mine, it is very difficult to achieve efficient and safe transportation and installation of the hydraulic support under such conditions.

[0003] Therefore, the hydraulic support will be transported by transport vehicles, but the loading of the hydraulic support on the transport vehicle is not firm and balanced enough, which may easily cause the hydraulic support to tilt or shift during transportation, and it is very easy for the transport vehicle to jump off the track or roll over. In the subsequent re-tracking process, crushing accidents are also prone to occur, affecting the safe and efficient production of the mine. Utility Model Content

[0007] As a preferred technical solution of the utility model, a groove is opened on the top of the vehicle plate, guide rollers are evenly arranged in the groove, and the guide rollers are rotatably arranged in the groove.

[0008] As a preferred technical solution of the utility model, the front side end of the vehicle plate is connected with an inclined guide plate via a hinge shaft.

[0010] As a preferred technical solution of the utility model, movable wheels are evenly arranged on the bottom of the vehicle plate.

[0011] As a preferred technical solution of the utility model, a push handle is provided on the top of the back plate.

[0012] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects:

A pressure plate 10 is sleeved on the telescopic shaft 9. The pressure plate 10 is a circular structure and is eccentrically sleeved on the telescopic shaft 9. The driving motor 16 provides power support for the rotation of the bidirectional screw 4. After the hydraulic support is loaded onto the vehicle plate 1, the bidirectional screw 4 rotates, and the screw pair 1 5 and the screw pair 2 6 convert the rotary motion of the bidirectional screw 4 into a linear reciprocating motion with opposite motion directions.
