Description

Technical Field

[0001] The invention relates to the technical field of coal mine tunnel excavation, and in particular to a coal mine tunnel rapid construction device and method. Background Art

[0002] There are main tunnels and connecting tunnels in coal mine tunnels. Since the tunneling equipment and transfer equipment are relatively large, the tunneling equipment and transfer equipment need to move the body and turn corners many times when turning from the main tunnel to the connecting tunnel, and even need to dismantle the body and reassemble it. The time spent on turning is relatively long, such as 48 hours. When tunneling at a bend, the connection between the conveyor belt of the tunneling equipment and the transfer equipment is no longer accurate, resulting in the advance of coal piling up at the bend. Other equipment is needed to re-transfer the coal at the bend, and the overall advance efficiency is low.

[0003] In view of this, there is an urgent need to develop a coal mine joint tunnel rapid construction device and method to overcome the above-mentioned defects. Summary of the invention

[0053] The specific implementation process of the present invention is described below through multiple embodiments.

[0055] See also Figures 1 to 14This embodiment discloses a specific implementation method of a coal mine joint tunnel rapid construction device.

[0056] See also Figures 1 to 14 A coal mine joint tunnel rapid construction device, comprising an anchoring and digging unit 1, a transfer unit 2 and a conveying unit 3; the anchoring and digging unit 1 comprises an excavation part 11, an anchoring part 12 and a first conveying part 13, a first tail swing mechanism 14 is arranged at the tail of the first conveying part 13, and the left and right swing angle of the first tail swing mechanism 14 is ±35°; the transfer unit 2 comprises a loading part 21, a second conveying part 22, a buffer container 23 and a third conveying part 24, a second tail swing mechanism 25 is arranged at the tail of the third conveying part 24, and the left and right swing angle of the second tail swing mechanism 25 is ±45°; the conveying unit 3 is parallel to the main tunnel 4 and close to the side of the main tunnel 4; the coal obtained by the excavation part 11 is successively conveyed to the conveying unit 3 through the first conveying part 13, the loading part 21, the second conveying part 22, the buffer container 23 and the third conveying part 24.

[0057] Specifically, see Figure 1 and Figure 2 When digging in the coal mine tunnel, it is necessary to dig in both the main tunnel 4 and the connecting tunnel 5.

The coal is no longer piled up at the turning point, and the vehicle body is no longer disassembled. The turning takes about 5 hours to 10 hours (the turning can be completed within one shift), and the turning efficiency is greatly improved; after the excavation part 11 enters the connecting lane 5, the first tail swing mechanism 14 swings 0° and aligns with the loading part 21, and the second tail swing mechanism 25 swings 0° and is perpendicular to the conveyor unit 3; through this embodiment, excavation and continuous coal transportation in various working conditions such as the main lane 4, the corner 6 and the connecting lane 5 can be realized, the adaptability is strong, and the footage efficiency is greatly improved.

When they swing left and right, they can still continuously convey coal.

This embodiment is applicable to the cross-sectional width of the connecting tunnel 5 of 2.5m-2.8m, the width of the anchor digging unit 1 and the transfer unit 2 is ≤2.5m; the volume of the buffer container 23 is not less than 4m 3 When the anchor mining unit 1 and the transfer unit 2 both enter the joint tunnel 5, when the transfer unit 2 cannot reach the conveying unit 3, the fully loaded coal in the buffer container 23 can be transported to the conveying unit 3 through the third conveying part 24 by reversing.

[0061] See also Fig.12 and Fig.13The anchor rod part 12 includes a first drilling arm assembly 121 and a second drilling arm assembly 122 set up on both sides of the body of the anchor digging unit 1.

Since the working principle of the third longitudinal movement assembly and the fourth longitudinal movement assembly is the same as that of the first longitudinal movement assembly 1231 and the second longitudinal movement assembly 1232, their purpose is to drive the second drill arm assembly 122 to be extended to the head 111 of the excavation section 11, and the details are not repeated.

[0063] Example 2

[0064] See also Fig.14 This embodiment discloses a specific implementation method of a coal mine joint tunnel rapid construction method.

[0065] See also Fig.14 The method for rapid construction of coal mine tunnels adopts the rapid construction device for coal mine tunnels described in Example 1, and comprises the following steps:

[0066] Step S1: The excavation unit excavates in the main tunnel, and the coal obtained by the excavation unit is successively conveyed to the conveying unit through the first conveying unit, the loading unit, the second conveying unit, the buffer container and the third conveying unit, and the third conveying unit is aligned with the conveying unit in a tail-swinging posture; specifically, the conveying unit 3 is placed near the side wall of the main tunnel 4 and parallel to the side wall, the anchor digging unit 1 and the transfer unit 2 cooperate to excavate in the main tunnel 4, and the third conveying unit 24 is aligned with the conveying unit 3 in a tail-swinging posture, and the conveying unit 3 follows the anchor digging unit 1 and the transfer unit 2.

[0067] Step S2: the excavation section 11 excavates at the corner 6. During the process of the excavation section 11 turning from the main tunnel 4 to the connecting tunnel 5, the first conveying section 13 is aligned with the loading section 21 in a tail-swinging posture, and the third conveying section is aligned with the conveying unit in a tail-swinging posture. Specifically, during the process of turning from the main tunnel 4 to the connecting tunnel 5, the corner 6 must be excavated first to dig out a turning space for the anchor-digging unit 1 and the transfer unit 2, and the first conveying section 13 and the third conveying section 24 both transport coal in a tail-swinging posture.

[0068] Step S3: After the excavation unit enters the tunnel, the first conveying unit is aligned with the loading unit in a non-tail swinging posture, and the third conveying unit is aligned with the conveying unit in a non-tail swinging posture. Specifically, after the anchor digging unit 1 and the transfer unit 2 enter the tunnel 5, the first conveying unit 13 and the third conveying unit 24 both transfer coal in a non-tail swinging posture; since the conveying unit 3 is a self-moving tail of the belt conveyor, after the anchor digging unit 1 and the transfer unit 2 enter the tunnel 5, the conveying unit 3 moves forward once to prepare for the subsequent excavation of the main tunnel 4 and the tunnel 5.

[0069] The coal mine joint tunnel rapid construction method of Example 2 adopts the coal mine joint tunnel rapid construction device of Example 1. For the parts in Example 2 that are the same as those in Example 1, please refer to Example 1 and will not be repeated here.
