Description
Technical field
The utility model relates to a kind of lame advanced supporting rack, relates in particular to a kind of sliding type cap for supporting mine roof advance support rack.
Background technology
Lame advanced supporting rack is the employed support in the junction of fully-mechanized mining working and crossheading.It mainly acts on is to realize the supporting of termination, tunnel top board and provide transporter and the elevating conveyor overlap joint, makes the supporting of entire working surface and propelling be able to carry out smoothly safely.Each big coal mine roadway advance timbering has at home obtained using widely at present, and advance support rack commonly used mostly is two one group structure.Entire bracket is enough become by multicomponent body frame.Section articulated back timber and the understructures of adopting on the overall structure, linkage mostly is the reverse-four-link-bar structure more.Progressively apply in the process at the tunnel advance timbering, show some shortcomings and defective gradually, FAQs is as follows:
1. because the characteristics of advance support rack working method determine that when shelf was passed forward, back timber must break away from top board.After back timber breaks away from top board, can produce the sky top of big distance,, destroy top board easily, be unfavorable for safety in production repeatedly to the top board ringing.Though the way of sliding advance of support is arranged at present, and it is unreliable to implement, and back timber also must break away from top board when the situation lower carriage that runs into the top board big rise and fall moves.
2. the advance support rack of Chang Yong two one group of forms, by about two form, poor aspect the stability of entire bracket.Especially under the condition with higher of tunnel, under the situation of back timber and top board disengaging, though there is the frame of accent jack to retrain on the back timber, reasons such as the fluctuating of base plate are easy to cause along with the propelling of support the generation of inclined to one side frame situation.
Summary of the invention
Of the present utility model designing and developing mainly is to solve the tunnel advance timbering in the passing process, faces the problem that produces the empty top of big distance.In the design, adopt the sliding structure of back timber, make set cap not break away from top board all the time, thereby avoid the lie top, reduced destruction to top board, effectively safe and efficient production can be realized in the supporting tunnel.
The purpose of this utility model provides a kind of novel sliding type cap for supporting mine roof advance support rack.
For achieving the above object, the technical solution adopted in the utility model is:
