DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

As shown in Figure 1, the straddle-type multifunctional transport drilling vehicle includes a gantry frame that can cross the tunnel boring machine and walking crawlers 1 arranged at the lower part of both sides thereof. The walking drive components of the straddle-type multifunctional transport drilling vehicle have a crawler structure that can adapt to complex road conditions and has a low failure rate. A support beam 7 that can telescope and laterally transport a temporary support 29 is arranged at the front end of the gantry frame. The support beam 7 realizes the main structure of the support transportation and is a retractable component. An anti-slip groove 8 is provided at the front end to facilitate the fixing of the temporary support support. The support beam has the functions of front and rear telescopic and lateral sliding. The front supporting column and the support beam cooperate with each other front and back to realize the obstacle crossing function of the temporary support. A hydraulic anchor drill arm 14 for rapid anchor support is arranged at the rear of the gantry frame to realize the rapid anchor support function of the drilling rig.

As shown in FIGS. 1 and 2 , the gantry frame includes side frames 2 on both sides and support beam brackets 3 connected to the top thereof, and the bottoms of the side frames 2 on both sides are connected to the track bases 101 on the walking track 1 .

As shown in FIG3 , a lateral slide 4 is provided in the joist support 3, a moving frame 5 and a lateral shift cylinder 10 are provided in the lateral slide 4, the bottom of the lateral shift cylinder 10 is connected to the side end of the lateral slide 4, and the piston rod of the lateral shift cylinder 10 is connected and fixed to the moving frame 5, and the lateral shift cylinder 10 drives the moving frame 5 to move laterally along the lateral slide 4, so as to adjust the lateral position of the joist 7 in the moving frame 5, thereby adjusting and correcting the lateral position of the temporary support;

A plurality of joist slideways 6 are arranged on both sides of the inside of the mobile frame 5, and a retractable joist 7 is arranged in each joist slideway 6. An anti-skid groove 8 which can limit the top beam of the temporary support 29 is opened at the front end of the joist 7. The plurality of joists 7 are drivingly connected to the joist telescopic cylinder 9 arranged in the mobile frame 5, and the front movement function of the joist 7 carrying the temporary support is realized by driving the joist telescopic cylinder 9.

As shown in FIG1 , the front and rear ends of the walking track 1 are provided with a protective shovel 11 fixed on a track base 101 for removing floating coal debris. The protective shovel 11 has the function of removing obstacles such as gangue, floating coal, metal supports, etc. and protecting the walking track when the straddle-type multifunctional transport drill vehicle moves forward. The front and rear ends of the track base 101 of the walking track 1 are provided with two front supporting columns 12 and rear supporting columns 13. The two front supporting columns 12 and rear supporting columns 13 support the drilling vehicle stably, thereby realizing the fixed body of the transport drilling vehicle and avoiding the deviation of the temporary support body when transporting.

As shown in Fig. 1 and Fig. 4, two hydraulic anchor drill arms 14 are arranged on both sides of the rear end of the joist support 3, and a transverse drill arm slideway 20 is arranged at the rear end of the joist support 3. A sliding seat 19 driven by a driving assembly is slidably connected in the drill arm slideway 20. The lateral position of the hydraulic anchor drill arm 14 in the tunnel is adjusted by the driving assembly to ensure the uniformity of the anchor support point. The outer end of the sliding seat 19 is connected to the support arm 15 through a rotary motor 17. The rotary motor 17 is adjusted to make the support span larger and its adaptability better. A sliding block slides in the support arm 15, and the sliding block moves up and down through a driver. A drilling rig 18 is fixed on the outside of the sliding block.

The drill arm slide 20 is arranged behind the support beam and is arranged in a transverse through-type arrangement to realize the left-right and right-left movement of the drill arm slide. The driver can move the drill rig 18 up and down. In addition, the action of the rotary motor 17 makes it easy to adjust the drilling position of the hydraulic drill rig during drilling.

As shown in FIG4 , the drive assembly and the driver are driven by a chain drive 21 and a telescopic cylinder 16 respectively. The chain drive 21 includes two gears supported in a drill arm slide 20 , a chain connected to a sliding seat 19 is arranged between the two gears, and any one of the gears is driven by a hydraulic motor 211 .

As shown in Figure 5, a connected oil tank 23 and a hydraulic pump 24 are provided in a box on one side of the side frame 2. The hydraulic pump 24 is connected to the front control valve group 25 and the rear control valve group 26 through hydraulic pipelines. The front control valve group 25 is connected to the driving motor 102 of the walking track 1 and the support beam telescopic cylinder 9, the side shift cylinder 10 and the front supporting column 12 and the rear supporting column 13 through hydraulic pipelines. The rear control valve group 26 is connected to the telescopic cylinder 16, the rotary motor 17, the drilling rig 18 and the hydraulic motor 211 through hydraulic pipelines.

As shown in FIG1 , a manual operating platform 22 is provided on one side of the side frame 2, and a manually controlled front control valve group 25 and a rear control valve group 26 are installed at the front and rear ends of the manual operating platform. The front control valve group 25 controls walking and support transportation; the rear control valve group 26 controls walking and hydraulic anchor drilling rig support.

The working principle of the straddle-type multifunctional transport drilling vehicle in the embodiment of the present application is as follows:

The front control valve group 25 controls the driving motor 102 to drive the walking crawler 1 to move, and moves to the corresponding position (the temporary support at the front end) so that the anti-skid slot 8 of the front support beam 7 is directly opposite to the top beam of the temporary support 29, and then the corresponding two side columns of the temporary support 29 and the upper lateral push rod are retracted to achieve the transport state. Since the temporary support 29 side adopts a double-column oil cylinder setting, the bottom width is as long as 0.6-0.8 meters, so the temporary support 29 is in a retracted state. Its stability is high and there is no dumping problem;

The transport drill vehicle moves forward until the walking crawler 1 approaches the rear edge of the shovel plate 28 of the comprehensive excavator 27, stops moving forward, operates the front support column 12 and the rear support column 13 to lift and stabilize the vehicle body, and then the joist telescopic cylinder 9 drives the joist 7 to move forward;

The forward supporting beam 7 pushes the temporary support to the predetermined position, and the transport vehicle supplies liquid to the temporary support. When the top beam of the temporary support is connected to the top, the horizontal push rod of the temporary support is opened to push the two side columns to the predetermined position. After firmly supporting the top plate and the two sides, the various devices of the transport drilling vehicle are recovered, and the equipment is returned to the anchor support position for anchoring operations. During the anchoring operation, the front-end comprehensive excavation machine 27 continues to dig and excavate, realizing the continuous operation of the comprehensive excavation machine 27. In this way, when the comprehensive excavation machine is cutting coal, the transport function is idle and converted to drilling and anchoring operations. The temporary support and the anchor drilling machine arranged at the rear of the transport drilling vehicle are used to make the support and coal cutting work in parallel, thereby realizing rapid excavation. At the same time, this device provides public performance services for transporting temporary supports and roadway support, liberating the support to simplify the control, lighten the weight, and improve safety as much as possible.

At the same time, the transport drill vehicle does not pass the shovel of the tunnel boring machine, so the span is reduced and the cross-section of the tunnel is relatively reduced, which is beneficial to the control of the tunnel surrounding rock pressure. In addition, the influence of floating coal is small and the forward movement is more flexible, which greatly improves the efficiency of transporting temporary supports by pickaxes. The forward-extending delivery support can make the temporary support move forward without being affected by the transport drill vehicle itself, and can make the temporary support move forward with a smaller distance from the head of the tunnel, greatly reducing the minimum empty top distance.

It also avoids the problem of having to retreat the tunnel boring machine during anchor support, enables continuous operation of the tunnel boring machine, and greatly improves the working efficiency of the tunnel boring machine.

A rapid excavation support method for a straddle-type multifunctional transport drilling vehicle comprises the following steps:

As shown in FIG6 , S1; the tunnel is formed by excavation of the tunneling machine 27, and a permanent support area is formed at the rear end of the tunneling machine 27;

As shown in Figure 7, S2; the excavator 27 is excavating forward, the transport drill car moves forward so that the anti-skid card groove 8 of the joist 7 is facing the outer temporary support 29 top beam, the temporary support 29 is operated to be in a retracted state, and the anti-skid card groove 8 of the transport drill car joist 7 is connected to realize lifting;

As shown in Figure 7, S3; the transport drill rig transports the temporary support 29 to the shovel plate 28 of the comprehensive excavator 27, and operates the front support column 12 and the rear support column 13 of the drill rig to raise the contact with the roof of the tunnel to stabilize the fuselage;

As shown in Figures 8 and 9, S4; the forward-moving support beam 7 allows the temporary support to pass over the shovel of the comprehensive excavator, and pushes the temporary support 29 to the predetermined position, unfolds the temporary support 29 to pre-connect the top beam, opens the horizontal push rod to push the two side columns to the predetermined position, pressurizes the temporary support to stably support the top plate and the two sides, and retracts the transport drilling vehicle to move back;

As shown in Figures 10 and 11, S5; when the temporary support range reaches the body of the tunnel boring machine, the transport drill vehicle retreats to the edge of the front anchor net 31 of the permanent support area behind the tunnel boring machine, and the tail hydraulic anchor drill arm 14 is operated to anchor the anchor support position. The tunnel boring machine can simultaneously perform parallel operations of coal cutting.

S6: After the anchoring is completed, continue to perform cyclic support operations according to steps S2-S5.
