Description
Technical Field
The utility model relates to a supporting field in the pit especially relates to a use combination formula forestope in pit.
Background
The underground support work is the important part of safety production, and especially the forward support plays a significant role in production safety. The existing forepoling support forms are roughly divided into two types, one is to utilize special hydraulic equipment to carry out forepoling support, and the other is to utilize anchoring parts such as anchor rods and the like to be matched with a forepoling component to carry out support. Wherein, the hydraulic equipment has inconvenient use because of larger volume and weight. The application is less, and the supporting work is difficult due to the condition that the arrangement of the anchoring points is not uniform and the like in the mode of supporting by utilizing the anchoring piece. And the equipment is difficult to recycle due to the arrangement form problem of the equipment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art weak point, provide a simple structure, safe and reliable, convenient to use's a combination formula forestope in the pit.
The equipment comprises an assembly base, wherein the assembly base is a main body supporting piece of the equipment and is also an assembly base piece;
a connecting lug plate is integrally arranged on the side edge of the assembling base, and a through hole is formed in the connecting lug plate; the through hole is used for fixing the whole device on the anchoring piece, and the fixing form can adopt a form of penetrating the anchor rod and being matched with the threaded sleeve for fixing.
The bottom surface of the assembly base is rotatably provided with a front canopy support; the front cantilever support is used for supporting the front cantilever and advancing the front cantilever forwards;
the front cantilever support is in a square frame form with two through ends, and a fastening piece is arranged on the bottom surface of the front cantilever support in a penetrating mode and used for fastening the front cantilever.
The front cantilever support is internally provided with a front cantilever in a penetrating way.
Further, the assembly base is in the form of an inverted terrace.
Furthermore, the forepoling bar support is rotatably arranged on the bottom surface of the assembly base through a male-female joint or a bearing.
Furthermore, the fastener adopts a fastening bolt form, and a supporting plate is arranged at the upper end head of the bolt.
The beneficial effects of the utility model are that: the utility model discloses simple structure, convenient to use, low in cost and easy to maintain have solved all sorts of problems to the forestope is strutted among the prior art through simple structure, have realized that simple and convenient forestope is strutted, arrange through the order of a plurality of equipment to and the forestope supports the rotation and sets up the form and its inside big space supplies the forestope to wear to establish and sets up the form, and the cooperation fastener forms the convenient forestope combination formula of safety and stability and struts.
