Description
Technical field
The utility model relates to production facility of coalmine technical field, specifically belongs to a kind of speedy drivage temporary support device.
Background technology
The foreset that most domestic underground coal mine driving face generally uses has: one is the temporary lining of hanging ring tube-through type forestope; Two is vehicle-mounted temporary support device for development machines; Three is adopt many row's hydraulic props to add high strength H shaped steel shack beam method of support etc.Although these modes alleviate driving face to a certain extent and to meet head on the pressure of supporting, improve the supporting situation of work plane, but it is little also to there is supporting power in actual use procedure, back is supported repeatedly, labor strength is large, there is larger hidden danger to equipment and operator in safety.The safety problem of driving face advance support is long-standing problem colliery speedy drivage safety in production technical barrier for many years; because top board after tunnelling can not obtain effective supporting in time; top board often can be caused to fall cash casualty accident, the efficiency of high-performance development machine cannot be given full play to.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of speedy drivage temporary support device, overcome the deficiencies in the prior art, simplicity of design, rational in infrastructure, carry out structure design targetedly, compact conformation for adapting to different tunnels condition, flexible operation, can improve driving speed and operating efficiency greatly.
The technical solution adopted in the utility model is as follows:
A kind of speedy drivage temporary support device, comprise girder, i iron hanger rail, pumping plant, working platform and protection shield, described girder front end is provided with brace summer, brace summer both sides are provided with brace summer rocking arm and support, the brace summer rocking arm other end is hingedly coupled on girder, brace summer rocking arm is also provided with the first hydraulic cylinder, first hydraulic cylinder rear end is fixed on girder, described protection shield is arranged at brace summer front end, described both sides, girder lower end chain connection has working platform rocking arm, described working platform rocking arm also connects the second hydraulic cylinder front end, second hydraulic cylinder rear end is fixedly connected on girder, working platform rocking arm is connected with working platform by connector, described main beam rear end is provided with material receiving, pumping plant is fixed on material receiving, between described girder and material receiving, both sides are provided with equalizer bar, equalizer bar lower end is provided with gripper shoe and supports, described girder and material receiving are all fixedly connected in gripper shoe, described i iron hanger rail is arranged at girder centre position, and described i iron hanger rail is provided with multiple suspension arrangement.
