Furthermore, a fixed block is horizontally and fixedly mounted on the bottom plate, a sliding through groove is formed in the fixed block, a clamping plate is inserted in the sliding through groove in a sliding mode, the clamping plate is perpendicular to the bottom plate, a plurality of threaded through holes are vertically and downwards formed in the fixed block and communicated with the sliding through groove, and locking pins are screwed in the threaded through holes.

The utility model has the advantages that: the utility model designs a novel end hydraulic support to replace a plurality of single hydraulic columns, has simple and convenient operation, can effectively improve the working efficiency, and can move forward by pulling the hydraulic support and operating the transfer hydraulic cylinder; the supporting area is large, and the labor intensity of operators is low; the support area can be adjusted according to actual conditions, the use is flexible and convenient, and the support device is worthy of being popularized and used in a large range.

Description of the drawings:

fig. 1 is a perspective view of the present invention;

FIG. 2 is a front view of the present invention;

fig. 3 is a perspective view of another view angle of the present invention;

FIG. 4 is a schematic view of the usage state of the present invention;

in the figure, a bottom plate 1, a vertical plate 2, a side plate 3, a threaded through hole 4, a hydraulic upright post 5, a fixing pin 6, a stop pin 7, a top plate 8, a hydraulic cylinder 9, a telescopic plate 10, a connecting seat 11, a chain 12, a migration hydraulic cylinder 13, a hydraulic support 14, a fixing block 15 and a clamping plate 16.

The specific implementation mode is as follows:

as shown in fig. 1 to 4, a novel end support hydraulic frame comprises a bottom plate 1 horizontally arranged, a plurality of vertical plates 2 are vertically welded on the bottom plate 1 along the length direction, side plates 3 are vertically and fixedly connected to both sides of each vertical plate 2, pin holes are uniformly formed in the vertical plates 2 and the side plates 3 from top to bottom, the vertical plates 2 and the side plates 3 contacting with the vertical plates 2 form a U-shaped mounting groove, a hydraulic column 5 is vertically arranged in the mounting groove, the bottom end of the hydraulic column 5 is hinged to a fixing pin 6, the fixing pin 6 is fixedly inserted into the pin holes on the vertical plates 2, a stop pin 7 is horizontally and fixedly inserted into the pin holes on the side plates 3, the top end of a piston rod of the hydraulic column 5 is hinged to a top plate 8, a plurality of hydraulic cylinders 9 are horizontally and outwardly fixed to both sides of the top plate 8 along the length direction, piston rods of the hydraulic cylinders 9 are fixedly connected with a vertically arranged telescopic plate 10, a connecting seat 11 is fixedly installed on the bottom plate 1, the connecting seat 11 is connected with a chain 12, the other end of the chain 12 is connected with a piston rod of a transfer hydraulic cylinder 13, and the bottom end of the transfer hydraulic cylinder 13 is connected with a hydraulic support 14; the bottom plate 1 is horizontally and fixedly provided with a fixed block 15, the fixed block is provided with a sliding through groove, a clamping plate 16 is inserted in the sliding through groove in a sliding mode, the clamping plate 16 is perpendicular to the bottom plate 1, the fixed block 15 is vertically and downwards provided with a plurality of threaded through holes 4, the threaded through holes 4 are communicated with the sliding through groove, and locking pins are screwed in the threaded through holes 4.
