Description

Technical Field

[0001] The invention relates to the technical field of anchor drilling vehicles, and in particular to a gantry platform type anchor drilling vehicle with a crawler walking function. Background Art

[0002] Anchor drilling rig is a kind of mechanical equipment specially used for reinforcement engineering. Its working principle is mainly based on drilling, grouting, anchor reinforcement and other processes to achieve stable reinforcement of engineering structures such as foundations, tunnels and bridges. When working, the anchor drilling rig first installs the drill bit and drill rod on the equipment, and starts to rotate and advance it through the drive system. In this process, the drill bit gradually penetrates into the stratum or rock while rotating to form the required borehole. As the drilling is completed, the drill rod and drill bit will be taken out, and then the anchor will be placed in the borehole. Mine tunnels usually face complex geological conditions, rock crushing and other problems. Therefore, the support and reinforcement of the tunnel is particularly important. The anchor drilling rig can quickly perform drilling and grouting operations in the tunnel to fix the anchor in the rock, thereby improving the stability and safety of the tunnel and ensuring the safety of the miners' working environment.

[0003] The current anchor drilling vehicle is usually equipped with a drill arm, which can drill one hole at a time. The drilling efficiency is low. The change of the drill rod angle mainly depends on the extension and rotation adjustment of the hydraulic cylinder. The drill arm of the current anchor drilling vehicle is relatively long. If the drill arm is in the extended state, the movement of the anchor drilling vehicle will be hindered in the narrow mine tunnel. When drilling holes in other locations, when changing the position of the drill bit, the drill arm needs to be retracted and then adjusted, which is constrained by the space of the mine tunnel. Summary of the invention

[0004] The invention provides a gantry platform type anchor drilling vehicle with a crawler walking function, which solves the problem in the prior art that the mine tunnel space is narrow and it is inconvenient to drill multiple holes at the same time.

[0005] The technical solution of the present invention is as follows:

[0006] A gantry platform type anchor drilling vehicle with crawler walking function comprises a base, a crawler assembly and a drill bit, wherein the crawler assembly is arranged at the bottom of the base, and further comprises:

[0007] A lifting platform, the lifting platform can be lifted and lowered on the base;

[0008] A gantry, the gantry being liftable and arranged on the lifting platform;

[0009] A movable frame, two movable frames are provided, and the movable frames can move horizontally and vertically along the gantry;

[0010] Drill arms, two drill arms are provided, the drill arms and the movable frames correspond to each other one by one, the drill arms can be raised and lowered and rotatably arranged on the movable frame, and the drill bit is arranged on the drill arms.

[0011] Furthermore, the mobile frame is provided with a longitudinal slider, the gantry frame is provided with a longitudinal slide groove matching the longitudinal slider in the vertical direction, the mobile frame is provided with a transverse slider, the gantry frame is provided with a transverse slide groove matching the transverse slider in the horizontal direction, the mobile frame is provided with a lifting member for pushing the mobile frame to be lifted and lowered and a walking member for driving the mobile frame to be moved transversely, and when the lifting member pushes the transverse slider to be lifted and lowered to the transverse slide groove, the walking member can drive the mobile frame to be moved transversely;

[0012] Wherein, the lifting member comprises:

[0013] A lifting plate, which is liftable and arranged at the bottom of the movable frame, and the lifting plate is in contact with the top of the base;

[0014] Wherein, the walking parts include:

[0015] A driving gear, the driving gear being rotatably disposed on the moving frame;

[0016] A fixed rack is disposed transversely on the gantry, and the driving gear is meshed with the fixed rack.

[0017] In order to realize the lifting and lowering of the drill arm, a feeding mechanism is arranged on the movable frame, and the drill arm is arranged on the movable platform of the feeding mechanism, which is used to drive the drill arm to be lifted and lowered.

[0018] In order to realize the rotation of the drill arm, a rotating assembly is provided on the feeding mechanism, and the rotating assembly is used to drive the drill arm to rotate in a vertical direction. The rotating assembly includes:

[0019] A rotating shaft is rotatably arranged on the moving platform of the feeding mechanism, and the drill arm is arranged on the rotating shaft.

[0020] In order to ensure the stability of the drill arm, a stabilizing mechanism is also included, and the stabilizing mechanism is used to ensure the stability of the drill arm after rotation, and the stabilizing mechanism includes:

[0021] A turntable, the turntable is arranged on the drill arm, and the rotating shaft and the turntable are coaxially fixedly connected;

[0022] The card frame is U-shaped and can be movably arranged on the moving platform of the feeding mechanism. The turntable is in contact with the inner side wall of the card frame.

[0023] In order to support the top of the mine tunnel, the top of the gantry is rotated and provided with a plurality of advance supports.

[0024] In order to facilitate the movement of the anchor drilling vehicle, a push shovel is arranged at the front end of the base.

[0025] The working principle and beneficial effects of the present invention are:

[0026] 1. In the present invention, the height of the drill arm is adjusted in multiple stages through the lifting and lowering of the lifting platform, the gantry, the mobile frame and the drill arm, that is, the height of the drill hole is adjusted, and the rising height of the drill arm is relatively high. The horizontal position of the drill arm can be adjusted by the lateral movement of the mobile frame along the gantry. The drill arm is driven to rotate by the rotating shaft to adjust the angle of the drill arm, so as to realize the drilling work at various positions in the mine tunnel. Two drill arms are used at the same time to realize the drilling work at two positions at the same time. The drilling position is adjusted by simple lateral and longitudinal movement and rotation of the drill arm, instead of driving the drill arm to rotate by a hydraulic cylinder to adjust the swing amplitude and the retraction and extension state of the drill arm, which is convenient to reduce the obstruction to the movement of the anchor drilling rig and speed up the drilling efficiency.

[0027] 2. In the present invention, other equipment used in the anchor drilling vehicle is installed on the lifting platform.

The gantry can drive the advance support to be lifted and lowered so that the advance support is provided at the front side of the anchor drilling vehicle to ensure the stability of the mine tunnel. The rotation of the advance support can adapt to the support of the top surface of the mine tunnel with different slopes.

[0028] 3. In the present invention, the drill arm is driven to rotate by the rotating shaft to adjust the drilling angle. The turntable rotates inside the clamping frame. After the drill arm rotates to a suitable angle, the clamping frame moves close to the turntable to fix the turntable, thereby ensuring the stability of the drill arm during drilling.

[0029] 4. Therefore, compared with the anchor drilling vehicle in the prior art that uses a hydraulic cylinder to drive the drill arm to rotate, the present invention uses crawler tracks to enable the anchor drilling vehicle to move in the mine tunnel, and the height of the drill arm can be freely adjusted by lifting and lowering the lifting platform, gantry, mobile frame and mobile platform. The mobile frame is driven by the walking parts to move horizontally along the gantry, and the drill arm is driven to rotate by the rotating shaft, so that the angle and position of the drill arm can be freely adjusted to meet the drilling needs at different positions. At the same time, the lifting and lowering of the gantry can drive the advance support to support and protect the top of the mine tunnel, thereby avoiding the obstruction of the movement of the anchor drilling vehicle caused by the large rotation of the drill arm in the prior art. At the same time, two different positions are processed synchronously by two drill arms, thereby improving the drilling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

While the driving gear 101 rotates under the action of the fixed rack 102, , driving the driving motor 105 and the moving frame 19 to move along the fixed rack 102, the transverse slider 18 moves to the inside of the transverse slide groove to ensure the stability of the moving frame 19, two longitudinal sliders 17 are provided, the two longitudinal sliders 17 are located at the top and bottom of the moving frame 19, the transverse slider 18 is located between the two longitudinal sliders 17, the rear end of the transverse slider 18 is tightly attached to the front end of the vertical frame of the gantry 14, avoiding the transverse slider 18 from hindering the longitudinal movement of the moving frame 19, the transverse frame of the gantry 14 is tightly attached to the rear end of the moving frame 19, a transverse inlet and outlet are provided at the bottom of the transverse frame of the gantry 14, the transverse inlet and outlet are connected to the transverse slide groove, so that the transverse slider 18 can enter and exit the transverse slide groove, and a longitudinal inlet and outlet are provided on the inner side of the longitudinal frame of the gantry 14,The longitudinal inlet and outlet are connected to the longitudinal chute. When the transverse slider 18 is raised or lowered to a position corresponding to the height of the transverse chute, that is, the transverse slider 18 enters the interior of the transverse inlet and outlet, the longitudinal slider 17 corresponds to the height of the longitudinal inlet and outlet. When the mobile frame 19 moves in the transverse direction, the longitudinal slider 17 moves out through the longitudinal inlet and outlet to avoid the longitudinal slider 17 hindering the transverse movement of the mobile frame 19.

[0049] like Figures 1 to 7 As shown, two drill arms 22 are provided, and the drill arms 22 and the mobile frames 19 correspond one to one. The drill arms 22 can be raised and lowered and can be rotatably arranged on the mobile frame 19, and the drill bit 3 is arranged on the drill arm 22. A feeding mechanism 23 is arranged on the mobile frame 19, and the drill arm 22 is arranged on a moving platform of the feeding mechanism 23, which is used to drive the drill arm 22 to be raised and lowered. The feeding mechanism 23 can selectively use a lead screw feeding mechanism 23, and the feeding structure is vertically arranged.

[0051] like Figure 6 to Figure 7As shown, in order to ensure the stability of the drill arm 22, a stabilizing mechanism is also included. The stabilizing mechanism is used to ensure the stability of the drill arm 22 after rotation. The stabilizing mechanism includes a turntable 301 and a clamping frame 302. The turntable 301 is arranged on the drill arm 22. The rotating shaft 201 and the turntable 301 are coaxially fixedly connected. The clamping frame 302 is U-shaped.

The turntable 301 can rotate inside the clamping frame 302. When the drill arm 22 rotates to a suitable angle, the electric cylinder 2 303 drives an inner side wall of the clamping frame 302 to be close to the surface of the turntable 301. There is a large sliding damping between the clamping frame 302 and the turntable 301, which ensures the stability of the turntable 301 and the drill arm 22, and reduces the displacement of the drill arm 22 under vibration when the drill arm 22 drives the drill bit 3 to rotate.

[0056] When drilling holes on the left and right side walls of the mine tunnel, the mobile frame 19 is in the vertical frame position of the gantry 14, the hydraulic cylinder three 21 pushes the mobile frame 19 to rise and fall, the feed mechanism 23 drives the drill arm 22 to rise and fall, and adjusts the height of the drill arm 22 to correspond to the drilling position, then the electric cylinder two 303 drives the clamping frame 302 away from the turntable 301, the electric cylinder one 203 drives the driving rack 204 to move, drives the rotating shaft 201 and the drill arm 22 to rotate, adjusts the angle of the drill arm 22, and then the electric cylinder two 303 drives the clamping frame 302 to clamp the turntable 301 to ensure the stability of the drill arm 22, and drives the drill bit 3 through the drill arm 22 to drill holes;

[0057] When it is necessary to drill a hole in the top wall, the hydraulic cylinder three 21 pushes the movable frame 19 to rise and fall, so that the height of the horizontal slider 18 and the horizontal slide groove correspond, the clamping spring drives the driving gear 101 to press on the surface of the fixed rack 102, and the driving motor 105 drives the driving gear 101 to rotate, so that the movable frame 19 moves laterally along the fixed rack 102, and then the electric cylinder two 303 drives the clamping frame 302 away from the turntable 301, the electric cylinder one 203 drives the rotating shaft 201 and the drill arm 22 to rotate, so that the drill bit 3 faces upward, the electric cylinder two 303 drives the clamping frame 302 to fix the turntable 301 and the drill arm 22, and the drill arm 22 drives the drill bit 3 to drill.
