Problems solved by technology

[0006] 1) Although the drill-bolt switching rate has been improved to a certain extent compared with the original bolt support scheme, there is still room for improvement;
[0007] 2) For rock bolters using double rock drills, two sets of propulsion systems are often used, which makes the propulsion beam very heavy and complicated to operate
[0009] Although this patent document solves the above-mentioned technical problems, those skilled in the art find that there are still deficiencies during use; theoretically, after the drilling mechanism completes a positioning, as long as the swivel frame rotates at a specific angle, the subsequent bolting operations and The anchoring operation does not need to be positioned again, but this is not the case in the actual operation process. For example, the entire drilling rig mechanism is in a state of vibration during drilling operations, and this will obviously cause a certain displacement of the drilling rig, so the subsequent rotation frame There is also a certain deviation after rotating a specific angle. In addition, how to ensure that the rotating frame rotates at a specific angle and the rotation angle error is small enough is not mentioned in the above patent documents

Embodiment 1

[0060] A hydraulic rock bolter, comprising an engineering chassis, a working arm, such as Figure 1-3 The three-station propulsion beam, electrical device, hydraulic device and cab are shown; among them, the engineering chassis is used to provide support for the whole vehicle to ensure the rigidity and strength of the whole vehicle, and the front lateral telescopic form of the legs of the engineering chassis can ensure The stability of the whole vehicle, the electrical device and hydraulic device are used to ensure the normal operation of the three-station propulsion beam and the working arm, and the cab is used to accommodate the driver and the driver manipulates the working arm and the three-station propulsion beam to complete the underground Support work; the three-station propulsion beam is installed on the working arm and adjusted to the vertical state through the working arm;

[0061] In this embodiment, the three-station propelling beam includes a bracket 1 installed on...

Embodiment 2

[0104] The difference between this embodiment and the first embodiment lies in that the anchoring device and the anchoring process are different.

[0105] In this embodiment, the anchoring device includes a bottom plate, a connecting pipe 90, the anchor assembly 53 in Embodiment 1, and a propulsion assembly for driving the push rod 91 to reciprocate; the connecting pipe 90 is fixedly installed on the upper half of the bottom plate, The propulsion assembly is installed on the bottom plate and is located below the connecting pipe 90;

[0106] The connecting pipe 90 includes a first pipe 901, a second pipe 902 and a third pipe 903 communicating with each other, and the first pipe 901 partially protrudes from the bottom plate; the anchor assembly 53 is connected with the third pipe 903 so that the anchoring agent After passing through the third pipeline 903 and the first pipeline 901 in sequence, it enters the hole drilled by the drilling device 4, and the propulsion assembly driv...

Abstract

The invention discloses a three-station propelling beam. The beam comprises a support installed on a working arm, a rotating beam installed on the support and a fixed beam, a drilling device used for completing drilling operation, a bolt anchoring device used for completing bolt anchoring operation and an anchoring device used for completing anchoring operation are installed on the rotating beam, and the drilling device and the bolt anchoring device are located on the two sides of the anchoring device respectively. The fixed beam is fixedly installed on the support, and the rotating beam is rotatably installed on the fixed beam in the rotating process. During drilling operation, the drilling device is located at a drilling position, during anchoring operation, the anchoring device is located at an anchoring position, and during bolt anchoring, the bolt anchoring device is located at a bolt anchoring position. The top end of the fixed beam always abuts against a roadway top plate needing to be anchored and is fixed. According to the technical scheme, the anchoring device is simple in structure, small in occupied space and very suitable for being assembled on the single propelling beam with three stations.

Description

technical field [0001] The invention relates to the technical field of mine and tunnel engineering machinery, in particular to a three-station propelling beam. Background technique [0002] Underground support (roadway support) is mainly used to ease and reduce the movement of surrounding rock, so that the section of the roadway will not be excessively reduced, and at the same time prevent the scattered and damaged surrounding rock from caving; usually, in order to make the roadway support adjust and control Playing an active role in the deformation process of the surrounding rock, the support should be installed before the surrounding rock becomes loose and damaged, so that the support can play a bearing role together with the surrounding rock when the surrounding rock still maintains self-supporting force. [0003] Take bolt support as an example; in the process of bolt support, it is necessary to drill the bolt hole first, and then knock in the bolt; Manual installation ...
