Abstract
The utility model relates to a lifting beam device of a roadway hydraulic bracket in the coal mine, and belongs to the technical field of the underground supporting equipment in the coal mine. In the technical proposal, two sets of lifting beam devices which have the identical and symmetric structures are respectively arranged at the two sides of a roadway hydraulic bracket door through a mounting plate; a hydraulic oil cylinder and a connecting rod are arranged on the mounting plate; the hydraulic oil cylinder is fixed on the mounting plate through a supporting seat; the end head of the piston rod of the hydraulic oil cylinder is hinged with the lower end of the connecting rod through pins; the lower part of the connecting rod is fixed on the mounting plate through pins; and a tray is fixed at the top of the connecting rod.
Description
Technical field
The utility model belongs to support apparatus technical field under the coal mine.
Background technology
The support apparatus of existing conventional face has beams of metal individual prop and slippage bracket, these two kinds of support apparatus are when reach, need artificial holder to rise back timber, the supporting back timber that supporting frame rear end is unloaded manually is installed in supporting frame front end, workman's working strength is big, efficient is low, and service speed is slow and dangerous.
Summary of the invention
The purpose of this utility model provides a kind of coal mine roadway and rises boom device with hydraulic support, can automatically header joist be risen when support moves and install, and can alleviate workman's working strength, increases work efficiency.
The utility model is achieved in that coal mine roadway rises boom device with hydraulic support, two covers that structure is identical and symmetrical rise boom device is fixed on tunnel hydraulic support door respectively by installing plate 3 both sides, hydraulic jack 4 and connecting rod 1 are housed on the installing plate 3, hydraulic jack 4 is fixed on the installing plate 3 by bearing, the piston rod end of hydraulic jack 4 is hinged by pin and connecting rod 1 lower end, the bottom of connecting rod 1 on installing plate 3, is fixed with carriage 2 on the top of connecting rod 1 by dowel fixes.
Compared with prior art the beneficial effects of the utility model are: owing to adopted the boom device that rises of hydraulic drive control, alleviated working strength of workers greatly when mobile supporting frame, improved production efficiency.
Description of drawings
Fig. 1 is the utility model coal mine roadway rises boom device with hydraulic support a structural representation.
The specific embodiment
As shown in Figure 1, two covers that structure is identical and symmetrical rise boom device is fixed on tunnel hydraulic support door respectively by installing plate 3 both sides, hydraulic jack 4 and connecting rod 1 are housed on the installing plate 3, hydraulic jack 4 is fixed on the installing plate 3 by bearing, the piston rod end of hydraulic jack 4 is hinged by pin and connecting rod 1 lower end, the bottom of connecting rod 1 on installing plate 3, is fixed with carriage 2 on the top of connecting rod 1 by dowel fixes.
Coal mine roadway is as follows with the course of work that hydraulic support rises boom device:
When the piston rod of hydraulic jack 4 was released, carriage 2 manually was placed on the supporting back timber on the carriage 2 at bottom position; Hydraulic jack 4 piston rods begin to shrink, and drivening rod 1 clockwise rotates an angle, hold up the upwards operation of supporting back timber, with the supporting back timber as for the top, tunnel.Then, the supporting frame is put the beams in place and is withstood the supporting back timber.
Next action: the piston rod of hydraulic jack 4 is overhanging, and drivening rod 1 rotates counterclockwise an angle, and connecting rod 1 end moves to the bottom that rises boom device downwards, so that the supporting back timber is placed on the carriage 2 once more.
Circulate repeatedly with this, finish the operation that automatic holder ascending branch protects back timber.
