Description
Technical field
Railway tunnel construction equipment technical field is the utility model is related to, is related specifically to a kind of tunnel davit bottom plate angle
Adjusting apparatus.
Background technology
Davit construction in the existing railway contact line engineering double track tunnel in China, generally using manual operation Small Drill Press
Carry out chemical anchor bolts Embedment Construction after pore-forming again one by one, it is necessary to make substantial amounts of davit bottom plate in work progress, bottom plate is being pacified
To be obliquely installed during dress, a batch tunnel davit is often done at present, different frocks can be all done according to different angle product.
Existing mode had not only taken but also labor intensive, and the frock after completing of constructing can not reuse, greatly
Waste material.
The content of the invention
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of simple in construction, energy
The frock of any angle product is enough provided, it is convenient and time-saving, and the repeatable tunnel davit base corner for utilizing, reducing waste of material
Spend adjusting apparatus.
To achieve these goals, the utility model uses following technical scheme：
Tunnel davit bottom plate angular adjustment apparatus, it is characterised in that include a base, two are symmetrically arranged with base
Individual support, connected by rotating shaft among support, and one piece of adjustment plate overturn with axis of rotation is installed in rotating shaft；It is described
Rotating shaft both ends bearing is installed, and arc-shaped scale is installed in the outer surface of rotating shaft one end, for indicating turning for adjustment plate
Dynamic angle, the rotating shaft other end is locking end, is provided with the nut being fixed on support, being passed through in nut has hold-down bolt, compresses
The compressible rotating shaft of the positive countershaft of bolt is located using frictional force and prevents from rotating；Described adjustment plate is divided into two by boundary of rotating shaft
Part, while being installation portion, another side is heavy burden portion, and the area of installation portion is more than the area in heavy burden portion, is unbalanced construction.
In such scheme, the center of circle of described dial and the axis coinciding of rotating shaft.
In such scheme, the centre of described adjustment plate is hollow structure, and rotating shaft passes through adjustment plate, is embedded to adjustment plate
In, and drive adjustment plate to rotate.
In such scheme, the nut on described support has a pair, is symmetrically mounted on rotating shaft both sides, two hold-down bolts
It is oppositely arranged while clamping shaft.
The utility model is by adopting the above-described technical solution, have the advantages that：
The utility model is simple in construction, using the teaching of the invention it is possible to provide the frock of the davit bottom plate of any angle product, it is convenient and time-saving, and
It is repeatable to utilize, reduce waste of material.

Whole plate 4；The described both ends of rotating shaft 3 are provided with bearing, and are provided with arc-shaped scale 5 in the outer surface of the one end of rotating shaft 3, for referring to
Show the rotational angle of adjustment plate 4, the other end of rotating shaft 3 is locking end, is provided with the nut being fixed on support 2, is passed through in nut
There is hold-down bolt 6, the compressible rotating shaft 3 of the positive countershaft 3 of hold-down bolt 6 is located using frictional force and prevents from rotating；Described tune
Whole plate 4 is that boundary is divided into two parts with rotating shaft 3, while being installation portion, another side is heavy burden portion, and the area of installation portion is more than heavy burden portion
Area, be unbalanced construction.
In the present embodiment, the center of circle of described dial 5 and the axis coinciding of rotating shaft 3.
In the present embodiment, the centre of described adjustment plate 4 is hollow structure, and rotating shaft 3 passes through adjustment plate 4, embedment adjustment
In plate 4, and adjustment plate 4 is driven to rotate.
In the present embodiment, the nut on described support 2 has a pair, is symmetrically mounted on the both sides of rotating shaft 3, two compression spiral shells
Bolt 6 is oppositely arranged while clamping shaft.
Particular embodiments described above, technical problem, technical scheme and the beneficial effect solved to the utility model are entered
Further description is gone, should be understood that and the foregoing is only specific embodiment of the utility model, and do not have to
In limitation the utility model, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done
