Description
Technical Field
The utility model relates to a roadway support equipment technical field especially relates to a suspension rail wing formula supporting platform.
Background
In the coal industry of China at present, generally, when a coal roadway is tunneled, the adopted supporting mode is bolt supporting. According to the requirements of coal mine safety regulations, a coal face must be supported in time, and the operation of an empty roof is strictly forbidden. If the empty roof distance is large and the empty roof time is too long, the safety accident of roadway collapse is easy to happen.
In the operation method, when the tunnel is tunneled for a period of time, the temporary support needs to be installed in time to protect the top of the tunnel so as to ensure that constructors do not operate under the 'empty roof'. And (3) the temporary support is synchronously moved forward along with the forward tunneling of the roadway, and at the moment, constructors immediately carry out permanent support on the 'empty roof' which is just removed from the temporary support. The construction method is low in efficiency, and has great potential safety hazard for workers who install and dismantle the temporary support to be exposed in the empty roof area for a long time. In addition, there are some devices or means that can act to support "empty top" roadways: if independent supporting mechanism by oneself or not, this kind of supporting mechanism structure is complicated, and it is also big to occupy the tunnel space, moves slowly, dismouting difficulty. No matter the temporary advance support or the independent support mechanism only plays a role of temporary support, the temporary advance support or the independent support mechanism is dismantled and then permanently anchored, namely, the operations of drilling anchor rods/anchor cable holes, hanging nets, injecting anchor rods/anchor cables and the like are carried out, so that the support efficiency is not high.
For example, in a new product tunneling and anchoring all-in-one machine appearing in recent years, an anchoring and protecting mechanism is arranged on a tunneling machine, anchoring and protecting operation is carried out after tunneling for a certain distance, equipment does not need to be withdrawn, and due to the fact that supporting operation cannot be carried out during tunneling, otherwise, tunneling operation cannot be carried out during supporting, namely synchronous operation cannot be carried out, operation efficiency is low, and in addition, the tunneling and anchoring all-in-one machine is complex in structure, low in working reliability, immature in product and unsatisfactory in use effect of the product.
In conclusion, the existing advance support mechanism has the defects of low working efficiency, large volume, difficult traveling and the like.
