Description

Technical Field

[0001] The utility model relates to the technical field of tunnel excavation machinery, in particular to a single-track hydraulic anchor drilling vehicle with two front and two rear translational drilling arms. Background Art

[0002] At present, in the tunneling construction of coal mines or non-coal mines in my country, the tunneling machines, rock drilling rigs, tunnel drilling rigs (drilling water and gas holes), anchor drilling vehicles and drilling and installation units used are all crawler or tire-type equipment walking on the ground. This type of tunnel construction equipment walking on the ground occupies a certain ground space size. Since the cross-sectional dimensions of the tunnels are relatively narrow, when these equipment want to enter the narrow tunnels for construction, the construction equipment of the previous process must be withdrawn first, and the equipment of this process can be driven in and carry out the corresponding construction operations. In this process, there is a long period of "empty top". If the geological conditions are not good and there is a large impact ground pressure, the empty top is prone to tunnel collapse, which can cause safety accidents in severe cases. This is prohibited by the "Coal Mine Safety Regulations". In addition, in order to ensure the safe passing of construction equipment, some mines have widened the tunnels, while others have built "avoidance lanes" at certain intervals in the tunnels. Whether widening the tunnels or building "avoidance lanes", it will have an impact on the geological structure and increase the cost of tunnel excavation and support; and the frequent entry and exit of equipment in the tunnel and misalignment will take up a lot of time, and require a lot of manpower to coordinate the command of reversing or entering the tunnel, etc., plus the tunnel is not well lit, and collisions are prone to occur during the passing process. Therefore, whether it is "empty top" or misalignment, there are safety hazards, which affects construction efficiency and leads to low tunnel excavation progress.

[0003] Now there are also suspended rail drilling and anchoring equipment on the market, but this type of suspended rail equipment generally adopts a wing arm mechanism (such as Figure 1 As shown in the figure, the drilling arm platform needs to be lowered by the wing-arm mechanism, and then the drilling rig assembly needs to be erected before drilling can be carried out. During use:

[0004] The drilling rig assembly can only stand up to drill around the section, but cannot drill forward;

[0005] The drilling rig assembly cannot adjust its position height according to the cross-section size and cannot adapt to the working conditions when encountering higher tunnels;

[0006] The manual service platform of the drilling rig assembly is not safe, people cannot move with the drill, and the operation is inconvenient. Utility Model Content

[0007] In view of the above situation existing in the prior art, the utility model provides a single-track hydraulic anchor drilling vehicle with two front and two rear translation drill arms. This anchor drilling vehicle does not occupy the ground space of the tunnel. The whole machine is suspended on the track at the top of the tunnel, the wing-type arm mechanism is cancelled, and a translation drill arm design is adopted. The translation drill arm can be translated up and down, left and right and can be telescopically adjusted in length, so that the operating table can reach any position in the tunnel, which greatly simplifies the structure of the whole machine and improves the convenience of operation and the scope of application of the whole machine; a frame assembly with front and rear telescopic function is adopted, so the position of the anchor drilling rig can be adjusted in the length direction, and multiple rows of anchors can be positioned and drilled at one time, thereby improving the construction efficiency; a three-way operating table with guardrails is adopted, and the construction personnel can operate simply, safely and conveniently.

[0008] The technical scheme adopted by the utility model to solve the problem is: a single-track hydraulic anchor drilling vehicle with two front and two rear translational drill arms, comprising a support platform, an anchor drilling machine, an operating table, a translational drill arm, a frame assembly, a track system, and a power station assembly; the front and rear of the frame assembly are respectively connected with the translational drill arm, the operating table, and the anchor drilling machine in sequence; the frame assembly comprises a frame assembly, a front gantry assembly, a rear gantry assembly, an outrigger assembly, a load-bearing trolley, a shoulder beam assembly, a driving assembly, a front telescopic inner arm, a front telescopic oil cylinder, a front telescopic outer arm, a rear telescopic inner arm, a rear telescopic oil cylinder, a rear telescopic outer arm, and a rear support assembly; the frame assembly is respectively connected with the front gantry assembly and the rear gantry assembly to form an integral frame, and the outrigger assemblies are respectively installed on the front gantry assembly and the rear On the gantry assembly, the carrying trolley and the driving assembly are installed on the shoulder pole beam assembly, the shoulder pole beam assembly is connected to the frame assembly, the rear support assembly is installed on the rear gantry assembly, the front telescopic inner arm is connected to the front telescopic outer arm through the front telescopic cylinder, the front telescopic outer arm is connected to the rear telescopic outer arm, the rear telescopic outer arm is connected to the rear telescopic inner arm through the rear telescopic cylinder, the front telescopic outer arm and the rear telescopic outer arm are respectively connected to the front gantry assembly, the rear gantry assembly and the frame assembly; the translation drill arm includes a translation seat, a translation cylinder, a telescopic inner arm frame, a telescopic outer arm frame, a telescopic cylinder, and a support arm cylinder, the translation cylinder is respectively connected to the translation seat and the telescopic inner arm frame through a pin shaft, the telescopic inner arm frame is connected to the telescopic outer arm frame through a telescopic cylinder, and the support arm cylinder is connected to the telescopic outer arm frame through a pin shaft.

[0009] Furthermore, the operating platform includes a multi-way valve group, an operating frame, a second spiral swing cylinder, a standing platform, and a first spiral swing cylinder; the multi-way valve group is arranged on the operating frame, the standing platform and the first spiral swing cylinder are arranged on the operating frame, and the second spiral swing cylinder is arranged on the first spiral swing cylinder.

[0010] The main beneficial effects of the utility model are as follows: the utility model adopts a unique "translational drill arm" design, a front and rear telescopic inner and outer sleeve structure of the frame assembly, and a follow-up operating table in the overall structure of the utility model, which makes it more convenient and safer for workers to construct, and can drive the anchor drill rig to operate 360° without dead angles in all directions. The existing monorail hanging track in the mine can be borrowed to save the cost of tunnel excavation. Since the track is suspended on the top of the tunnel through multiple sets of hanging components, the safety is guaranteed, and it does not occupy the lower space of the tunnel. It can "pass in space" with other construction equipment and will not affect the passage of other ground construction equipment and personnel. Since the equipment adopts a staggered and overlapped, flattened compact design, it can adapt to the excavation of narrow tunnels; the retraction and support operations are simple and convenient. Therefore, compared with the ground walking anchor drill rigs or the same type of monorail hydraulic anchor drill vehicles on the market, the utility model is convenient and safe to operate, has more complete functions, better performance, and a wider range of adaptability.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in combination with specific implementation modes according to the accompanying drawings.

[0024] like Figure 1 As shown, the existing suspended rail drilling and anchoring equipment generally adopts a wing-type arm mechanism 4, and the drilling arm platform 3 needs to be lowered by the wing-type arm mechanism, and then the drilling rig assembly 1 is erected before drilling construction. During use: the drilling rig assembly can only be erected to drill holes around the section, and cannot drill holes forward; the drilling rig assembly cannot adjust its position height according to the size of the section, and cannot adapt to the working conditions when encountering a higher tunnel; the manual service platform 2 of the drilling rig assembly is unsafe, and people cannot move with the drill, which is inconvenient to operate.

[0025] like Figure 2-11As shown, the utility model is a single-track hydraulic anchor drilling vehicle with two front and two rear translational drill arms, comprising a support platform 5, an anchor drilling machine 6, an operating table 7, a translational drill arm 8, a frame assembly 9, a track system 10 (tracks, hanging components, etc.), and a power station assembly 11 (including a hydraulic system, an electrical system, etc.); the frame assembly 9 is connected to the translational drill arm 8, the operating table 7, and the anchor drilling machine 6 in sequence at the front and rear; the frame assembly 9 comprises a frame assembly 9.1, a front gantry assembly 9.2, a rear gantry assembly 9.3, a leg assembly 9.4, a load-bearing trolley 9.5, a shoulder beam assembly 9.6, a drive assembly 9.7, and a front extension assembly 9.8. The telescopic inner arm 9.8, the front telescopic oil cylinder 9.9, the front telescopic outer arm 9.10, the rear telescopic inner arm 9.11, the rear telescopic oil cylinder 9.12, the rear telescopic outer arm 9.13, the rear support assembly 9.14, the frame assembly 9.1 is connected with the front gantry assembly 9.2 and the rear gantry assembly 9.3 to form an integral frame, the leg assembly 9.4 is respectively mounted on the front gantry assembly and the rear gantry assembly, the load-bearing trolley 9.5 and the drive assembly 9.7 are mounted on the shoulder pole beam assembly 9.6, the shoulder pole beam assembly 9.6 is connected with the frame assembly 9.1, the rear support assembly 9.14 is mounted on the rear gantry assembly, the front telescopic The inner arm 9.8 is connected to the front telescopic outer arm 9.10 through the front telescopic cylinder 9.9, the front telescopic outer arm 9.10 is connected to the rear telescopic outer arm 9.13, the rear telescopic outer arm 9.13 is connected to the rear telescopic inner arm 9.11 through the rear telescopic cylinder 9.12, the front telescopic outer arm 9.10 and the rear telescopic outer arm 9.13 are respectively connected to the front gantry assembly 9.2, the rear gantry assembly 9.3 and the frame assembly 9.1; the translation drilling arm 8 includes a translation seat 8.1, a pin shaft, a translation cylinder 8.2, a telescopic inner arm frame 8.3, a telescopic outer arm frame 8.4, a telescopic cylinder 8.5, an arm cylinder 8.6, and a translation cylinder 8. 2 is respectively connected with the translation seat 8.1 and the telescopic inner arm frame 8.3 through a pin shaft, the telescopic inner arm frame 8.3 is connected with the telescopic outer arm frame 8.4 through a telescopic oil cylinder 8.5, and the support arm oil cylinder 8.6 is connected with the telescopic outer arm frame 8.4 through a pin shaft; the operating platform 7 comprises a multi-way valve group 7.1, an operating frame 7.2, a second spiral swing oil cylinder 7.3, a standing platform 7.4, and a first spiral swing oil cylinder 7.5; the multi-way valve group 7.1 is arranged on the operating frame 7.2, the standing platform 7.4 and the first spiral swing oil cylinder 7.5 are arranged on the operating frame, and the second spiral swing oil cylinder 7.3 is arranged on the first spiral swing oil cylinder 7.5.

[0026] When working, the hydraulic oil pump rotates under the drive of the motor, and the hydraulic oil sucked from the hydraulic oil tank is converted into high-pressure oil through the pipeline to the multi-way valve. Under the control of each operating handle, the high-pressure oil flows through the hydraulic oil pipe to each actuator (such as hydraulic cylinder, hydraulic motor, rotary reducer, etc.) and completes the corresponding action. The low-pressure hydraulic oil that has done work returns to the hydraulic oil tank after heat dissipation through the radiator, completing a cycle. The driving wheel rotates under the drive assembly motor. The friction between the driving wheel and the track makes the whole machine move forward or backward along the track, and the brake can be braked under the action of the brake assembly. When working, the support assembly is operated as needed to complete the support of the top, second side or front face of the tunnel to ensure construction safety. The operating platform is controlled to rise or fall by operating the translation drill arm, and swing left or right to the required position; the length of the drill arm can also be adjusted by operating the telescopic cylinder of the translation drill arm, so as to meet the needs of adjusting the position of the anchor drill rig on the operating platform. After stopping the machine once to drill and support one row of anchor rods, the extension length of the telescopic inner arm can be controlled by operating the frame assembly, thereby controlling the operating table to reach the predetermined position, and the second and third rows of anchor rods can be constructed.

[0027] The two groups of anchor drilling rigs on the left and right and in the front and back are operated independently without interfering with each other. They can drill holes in the entire section or head-on. By controlling the extension of the telescopic inner and outer arms of the translational drill arm, multiple rows of anchor cable holes can be drilled at one time in a stable machine state; the rear support assembly, the frame assembly leg assembly and the telescopic inner and outer arms of the translational drill arm can be retracted and extended by hydraulic (single-stage or multi-stage telescopic cylinder) or pneumatic or electric or mechanical mechanisms, and the number and layout of the support mechanisms can also be determined according to actual working conditions.

[0028] The track system used can be directly utilized on the existing monorail crane track in the mine, or it can be temporarily laid as needed.

[0029] The above implementation modes are only used to illustrate the technical solution of the utility model and are not intended to limit it. Parts not described in detail, such as automatic control, etc., belong to the prior art. Although the utility model is described in detail with reference to specific embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, and should be included in the scope of protection of the claims of the utility model.
