Description
Technical Field
The utility model belongs to tunnel construction field, concretely relates to vertical drilling appurtenance at subway and passenger dedicated line railway tunnel top drilling construction.
Background
The typical tunnel boring tool is operated manually, the boring tool is aligned with a bored position, perpendicularity is visually observed, and then boring operation is performed. The verticality of the hole positions is closely related to the installation quality of the overhead line system suspension and the later train operation. Therefore, the verticality of the hole position of the drill hole is an important link for ensuring the safety of the suspension system and the reliable and efficient operation of the train. Item 6 in the construction quality acceptance standard of subway power supply system engineering (an alternating current 35Kv system and a direct current 1500V system) clearly specifies that the verticality or plumb tolerance of the rod to the tangent line of the tunnel arch wall is not more than 10.
Along with the development of the electrified railway, the application of the contact network is more and more extensive, and the requirement on the suspension drilling of the contact network is higher and higher, and the common manual drilling mode is less and less suitable for modern construction due to poor precision and low efficiency. The main reasons are as follows: manual drilling can result in increased drilling perpendicularity errors due to human arm strength and visual uncertainty, and the buried anchor bolt and the installed suspension quality standards are reduced. Therefore, the novel tunnel drilling auxiliary tool is an effective way for improving the one-step forming of the perpendicularity of the tunnel construction drill hole.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the deficiencies in the prior art, the technical problem who solves is: a vertical tunnel drilling auxiliary tool for drilling construction in a tunnel is provided.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a tunnel appurtenance that drills perpendicularly, includes mound ground base, electric drill installation base, rack seat, clamping part, waves the handle, the rack seat is vertical to be fixed on mound ground base, and electric drill installation base establishes on rack seat through clamping part cover, be provided with on the electric drill installation base with rack seat on the rack complex gear, the gear through the pivot with wave handle 5 and be connected, the pivot passes through the bearing setting and is in on the electric drill installation base.
The pier foundation is arranged on the horizontal ground or the plane of the ladder truck.
The buckling part is fixedly connected with the electric drill mounting base through a bolt.
Compared with the prior art, the utility model following beneficial effect has: in the utility model, the drilling tool and the auxiliary tool are firmly combined; the auxiliary tool pier is placed on a horizontal ground or a ladder car, and the lower disc is stable and is not easy to shake left and right; the perpendicularity of the drilling tool is guaranteed by mechanical force, and errors caused by manpower are avoided. Therefore, the utility model provides a tunnel vertical drilling appurtenance has that actual operation is convenient, the cost is low, drilling success rate is high, drilling quality is high, weight is lighter be convenient for remove the characteristics of unloading, is applicable to the interior drilling construction of tunnel very much.
