Description

Technical Field

[0001] The utility model relates to the technical field of tunnel excavation machinery, in particular to a slide rail type single rail hydraulic anchor drilling vehicle. 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equipment want to enter the narrow tunnels for construction, the construction equipment of the previous process must be withdrawn first, and the equipment of this process can be driven in and carry out the corresponding construction operations.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 in the market, but this type of suspended rail equipment generally uses a wing-type arm mechanism, which requires the wing-type arm mechanism to lower the drilling arm platform and then stand up the drilling rig assembly before drilling construction. However, there are still the following problems during use:

[0004] 1. The drilling rig assembly can only stand up to drill around the section, but cannot drill forward;

[0005] 2. 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] 3. The manual service platform of the drilling rig assembly is not safe, and people cannot move with the drill, making operation inconvenient. Utility Model Content

[0007] In view of the problems existing in the above-mentioned prior art, the utility model provides a sliding rail type single-rail hydraulic anchor drilling vehicle. 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 translation drill arm is eliminated and a translation drill arm design is adopted. The translation drill arm can be translated up and down, left and right and can be retracted to adjust the 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 operational convenience and applicability of the whole machine. A sliding rail type drill arm platform with a rack is adopted, which allows the slide rail trolley to move back and forth on the drill arm platform through the driving motor to rotate the driving gear meshing with the rack, and can locate and drill multiple rows of anchors at a time, thereby improving the construction efficiency. A three-way operating table with guardrails is adopted, which is simple, safe and convenient for construction personnel to operate.

[0008] The technical solution adopted by the utility model for the technical problem to be solved is: a slide rail type single-rail hydraulic anchor drilling vehicle, which includes a support platform, an anchor drilling rig, an operating table, a translational drill arm, a frame assembly, a slide rail trolley, a slide rail type drill arm platform, a variable amplitude mechanism, a track system and a power station assembly, wherein the support platform is located at the front end of the anchor drilling vehicle, the anchor drilling rig is located at the rear of the support platform, the operating table is located at the rear of the anchor drilling rig, and the translational drill arm is located at the rear of the operating table; the frame assembly includes a main frame, a load-bearing beam assembly, a central support leg and an adjustment cylinder, the main frame is connected to the load-bearing beam assembly, a load-bearing trolley is installed on the load-bearing beam assembly, and the main frame is connected to the central support leg through a pin shaft and an adjustment cylinder; the variable amplitude mechanism is composed of a swing seat, a strut assembly, a variable amplitude cylinder, a follower seat, a movable arm assembly and a pin shaft to form a parallelogram machine The structure is installed at the left and right ends of the main frame through a pin shaft; the slide trolley includes a slide assembly, a pulley, a drive motor and a drive gear, and the slide trolley can slide on the slide-type drill arm platform under the action of the pulley and the drive gear; the slide-type drill arm platform includes a leg assembly, a connecting seat, a rack, a crossbeam, a sealing plate, a left beam and a right beam; the operating table includes a multi-way valve group and an operating frame, the multi-way valve group is installed on the operating frame, the large spiral swing cylinder is installed on the operating frame, the small spiral swing cylinder is installed on the large spiral swing cylinder, and can drive the anchor drill rig to rotate 360°; the translation drill arm includes a translation seat, a translation cylinder and a support arm cylinder, the translation seat is connected to the translation cylinder and the telescopic inner arm through a pin shaft, the telescopic inner arm is connected to the telescopic outer arm through the telescopic cylinder, and the support arm cylinder is connected to the telescopic outer arm through a pin shaft.

[0009] When the utility model is 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 to each actuator (such as hydraulic cylinder, hydraulic motor, rotary reducer, etc.) through the hydraulic oil pipe 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, and a cycle is completed. The driving wheel rotates under the drive assembly motor, and the friction between the driving wheel and the track causes the whole machine to move forward or backward along the track, and the brake can be braked under the action of the brake assembly. During work, 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 oil cylinder of the translation drill arm, thereby meeting the need for adjusting the position of the anchor drill on the operating platform. After stopping the machine to drill and support one row of anchor bolts, the slide trolley can be used to slide on the slide-type drill boom platform to control the operating table to reach the predetermined position, and the second and third rows of anchor bolts can be constructed.

[0010] The left and right groups of anchor drilling rigs are operated independently without interfering with each other. They can drill holes in the entire section or head-on. They can be extended by controlling the telescopic arm of the translational drill arm, and multiple rows of anchor cable holes can be drilled at one time in a stable machine state. The rear support assembly, frame assembly leg assembly and drill arm translational leg assembly can be retracted and extended by hydraulic (single-stage or multi-stage telescopic cylinder) or pneumatic or electric or mechanical mechanisms. The number and layout of the support mechanisms can also be determined according to actual working conditions.

[0011] 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.

[0012] The main technical features of this utility model are as follows:

[0013] 1. The unique "translatory drill arm" design is adopted in the whole machine structure: the translation seat is connected with the translation cylinder and the telescopic inner arm through a pin shaft, the translation cylinder is connected with the translation seat and the telescopic inner arm through a pin shaft, the telescopic inner arm is connected with the telescopic outer arm through the telescopic cylinder, and the support arm cylinder is connected with the telescopic outer arm through a pin shaft.

[0014] 2. The use of a follow-up operating table makes it more convenient and safer for workers to work: the multi-way valve group is installed on the operating frame, a large spiral swing cylinder is installed on the operating frame, and a small spiral swing cylinder is installed on the large spiral swing cylinder, which can drive the anchor drill to operate 360° without dead angles.

[0015] 3. The frame assembly adopts a luffing mechanism structure: the load-bearing trolley is installed on the load-bearing beam assembly, the load-bearing beam assembly is connected to the main frame, and the front and rear two sets of luffing mechanisms are installed on the left and right ends of the main frame through pins, and the central leg is connected to the main frame through pins and adjustment cylinders. The luffing mechanism is composed of a swing seat, a strut assembly, a luffing cylinder, a follower seat, a boom assembly and a pin to form a parallelogram mechanism.

[0016] 4. The slide trolley consists of a slide assembly, pulley, drive motor, drive gear and various pins.

[0017] 5. The slide rail type drilling boom platform consists of a leg assembly, a connecting seat, a rack, a cross beam, a cover plate, a left beam, a right beam, etc.

[0018] The utility model is suspended on the track at the top of the tunnel, and the track is the same as the monorail track, so the existing monorail track in the mine can be used, thereby saving 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" with other construction equipment in space, and will not affect the passage of other ground construction equipment and personnel. Since this equipment adopts a staggered overlap and flattened compact design, it can adapt to the excavation of narrow tunnels.

[0019] In addition, the use of central outriggers to support the tunnel floor, support platforms to support the tunnel top and sides, and front and rear lower outriggers of the working platform to support the ground can ensure the stability of the anchor drilling rig during operation; all supports are hydraulically controlled, and the retraction and support operations are simple and convenient.

[0020] Compared with the ground walking anchor drilling rig or the same type of monorail hydraulic anchor drilling vehicle currently on the market, the utility model is convenient and safe to operate, has more complete functions, better performance and a wider range of adaptability.
