Problems solved by technology

For suspension drilling, Chinese invention patent application number 201210151763.7 discloses a tunnel drilling machine, and Chinese utility model patent application number 201320675236.6 discloses a lifting laser positioning high-space boom drilling device. The two technical solutions only It solves the technical problem of punching a single hole without the need for people to climb high, and obviously does not solve the problem of using an automatic punching trolley to punch suspension holes in subway tunnels automatically
At present, there is no method and technical solution that can use automatic punching equipment to punch holes in subway tunnels in the prior art.

Embodiment 1

[0045] Embodiment one (circular tunnel section formed by shield method)

[0046] See attached image 3 and attached Figure 4 , a kind of subway tunnel suspension automatic perforating trolley of the present invention comprises trolley structure system, perforating driving device 4, power supply unit 10, traveling device 14, braking device 7, console 6, and control system.

[0047] The trolley structure system is composed of a trolley base 1, a first transverse slideway 2, a first support system 3, and an inspection escalator 11.

[0048] see attached Figure 5 And attached Figure 6 , trolley base 1, including a pair of passive running wheels 1.1 and a pair of driving wheels 14.4 located on the trolley base 1, running rails 20, trolley inclined bars 1.2, cross bars 1.3, and longitudinal bars that are assembled and welded to form a frame structure 1.4, the bearing ear plate 1.5 welded to the corresponding position on the frame structure, and the fixed connecting plate 1.6....

Embodiment 2

[0095] Embodiment two (rectangular tunnel section formed by open cut method)

[0096] See attached figure 1 , attached Figure 15 and attached Figure 16 . The cross-section of the tunnel formed by the cut-and-open method is generally rectangular. The difference between the second embodiment and the first embodiment is that the trolley structure system is different, and the other parts are basically the same as the first embodiment.

[0097] The trolley structure system includes a second transverse slideway 17 and a second support system 19. The second transverse slideway 17 is composed of two vertical slideways 17.1 and a horizontal slideway 17.2, wherein the vertical slideway 17.1 and the horizontal slideway 17.2 form a rectangular structure corresponding to the section of the tunnel. The second support system 19 includes horizontal and vertical connecting rods and auxiliary support slanting rods 19.1. Among them, the auxiliary support slanting rod 19.1 is symmetrically...

Embodiment 3

[0100] See attached Figure 20, as a further improved embodiment, the difference between this embodiment and embodiment one or embodiment two is that: the number of groups of the first transverse slideway 2 or the second transverse slideway 17 has been added to more than two groups, and in the first Several groups of longitudinal slideways 2-1 are added on the transverse slideway 2 or the second transverse slideway 17, specifically the first transverse slideway 2 or the second transverse slideway 17 are arranged in parallel and spaced along the longitudinal direction of the trolley base 13 Groups, each group of the first transverse slideway 2 or the second transverse slideway 17 is equipped with several groups of vertical slideway 2- 1. The longitudinal slideway 2-1 is provided with a chute for installation along the length direction of the slideway. The chute preferably uses a T-shaped groove 2.1, and the base of the driving push rod 4.3 is connected to the slideway of the lo...

Abstract

A method of using an automatic drilling jumbo to drill a suspending hole in a subway tunnel comprises the steps of (1), mounting a first transverse slide or second transverse slide in corresponding shape to the tunnel section along the transverse direction of the jumbo; (2), mounting on the second transverse slide, a plurality of sets of drilling drivers that are movable along the second transverse slide and fixable; (3) connecting heads of driving push bars to percussion drills, connecting bases of the driving push bars to the first transverse slide or the second transverse slide, and mounting a travel control device at each driving push bar, wherein each driving driver includes the drive push bar and the percussion drill; (4), mounting a control system on the jumbo, and automatically controlling, by the control system, a jumbo travelling device, brake devices and the driving drivers through modules, wherein (5) the modules include, a power module, a jumbo traveling module, a travelling distance module, and a drilling drive module. The method allows automated drilling for mounting holes for subway tunnel suspension supports, and drilling efficiency is greatly improved accordingly.

Description

technical field [0001] The invention relates to tunnel construction mechanical equipment, in particular to a method for drilling suspension holes with an automatic drilling trolley in a subway tunnel. Background technique [0002] In order to alleviate the needs of urban traffic, stimulate the national economy, and also serve as civil air defense, my country has carried out large-scale subway construction in recent years. In the construction of subway tunnels, after the civil works are completed, that is, when the station works start, many specialties need to drill thousands of sets of installation holes on the tunnel wall along the line direction of the tunnel for the installation of different professional cable supports and catenary. For brackets, water supply and drainage brackets, etc., the size of the installation holes and the horizontal and vertical dimensions of each profession are basically the same. see figure 1 and figure 2 ,in figure 1 It shows the brackets ...
