Embodiment 2

[0039] The second embodiment is: due to the requirements of the process or the lateral movement of the three, the lateral width of the fixed frame is too large, resulting in poor structural design stability and complicated process operations. Therefore, a further design is carried out, that is, the bolt support mechanism includes a rock drill Assembly 400, bolter head assembly 500 and grouting assembly 600, the grouting assembly 600 is arranged on the rock drill assembly 400, or on the bolter head assembly 500, or on the working end side of the push beam 100, From the perspective of convenient process operation, this embodiment is preferably as follows: the grouting assembly 600 is arranged on the working end side of the push beam 100, and this structure will also be described in detail below; when the grouting assembly 600 and the push beam 100 A swing assembly 700 is arranged therebetween, and the swing assembly 700 drives the grouting pipe of the grouting assembly 600 to cha...

Embodiment 3

[0042] Embodiment 3: This embodiment further discloses the structure of the fixing frame. Specifically, the fixing frame includes a left bracket 202, a right bracket 203, and a front fixing bracket 204 and a rear end arranged at both ends of the left bracket and the right bracket. Fixed frame 205, movable frame 300 is arranged between left support 202 and right support 203, is provided with corresponding transverse slideway between left support 202, right support 203 and movable frame 300, thus, can make bolt support The mechanism slides in the transverse slideway, that is, the determination of the positions of the three stations is realized through the left bracket 202, the right bracket 203 and the movable frame 300. This embodiment is used to meet the second embodiment and when the bolt support mechanism includes a rock drill Assembly 400, bolt head assembly 500 and grouting assembly 600 when two of them are in the situation, is a further deepening of the above-mentioned emb...

Embodiment 4

[0043] Embodiment 4: For Embodiment 3, for the structural design of the lateral movement and longitudinal movement of each component of the bolt support mechanism, and optimize the control structure, this embodiment is provided with multiple supporting slides 209 arranged side by side in the horizontal slideway Each component in the bolt support mechanism is matched and supported on the corresponding support slide plate 209; a guide sleeve 210 is provided on each support slide plate 209, and a drive pin shaft 211 is provided for matching and sliding in the guide sleeve 210, and the second power The assembly 201 is arranged between the drive pin shaft 211 and the fixed frame. Specifically, as shown in the figure, the second power assembly 201 is an oil cylinder, and the drive pin shaft 211 is arranged on the cylinder body of the oil cylinder, and the end of the piston rod of the oil cylinder is arranged On the fixed frame; when it moves, the second power assembly 201 drives the ...

Abstract

The invention belongs to the technical field of tunnel construction. A multi-station mechanized switching mechanism for bolting construction. The mechanism comprises a propulsion beam, a fixed frame,a movable frame and a bolting mechanism, wherein the fixed frame is fixedly disposed on the propulsion beam; the movable frame is matched and disposed on the propulsion beam in the sliding mode, and the fixed frame and the movable frame are laterally disposed correspondingly. The bolting mechanism comprises at least two of a rock drill assembly, a bolt head assembly and a grouting assembly, and all the assemblies of the bolting mechanism are laterally arranged on the fixed frame and the movable frame in the sliding mode. The invention further discloses a bolt construction device. The overall structure design is reasonable, and automatic switching of drilling, bolt loading and grouting is achieved, so that construction workers are greatly liberated from the heavy labor intensity and the harsh construction environment. At the same time, the construction cost is reduced under the environment that the labor cost is higher and higher, and greater profits are created.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a multi-station mechanized switching mechanism for bolt support construction and bolt construction equipment. Background technique [0002] As the main support means of tunnel drilling and blasting construction, bolt support is to drive the bolt into the surface rock mass or the pre-drilled hole in the rock mass around the chamber. The slab may rely on the bonding effect to combine the surrounding rock and the stable rock mass to produce a suspension effect, a composite beam effect, and a reinforcement effect, so as to achieve the purpose of reinforcement and support. The quality and efficiency of bolt support is the key to measure the quality of an engineering project, which directly affects the quality, schedule and cost of the project. [0003] With the development of science and technology, the construction technology of bolt support has also develope...
