Description

Technical Field

[0001] The invention belongs to the technical field of mining machinery, and in particular relates to a mobile raise boring machine with rail wheels and tires capable of rapid switching, and a raise boring machine. Background Art

[0002] A raise drilling rig is a mechanical equipment for shaft excavation that can drill holes through rock through rotary drilling and can also expand the holes in reverse. A raise drilling rig mainly includes: a main machine part that performs the drilling work and a pump station part that provides power to the main machine part.

[0003] Most existing shaft drilling rigs have a main engine part and a pump station part that are separate and cannot be moved by themselves. Before transportation, the drilling rig must first be disassembled and then transported separately by another special tractor. When it is transported to the site for drilling work, it must be reassembled, which is inconvenient to transfer.

[0004] In addition, some drilling rigs have many large parts. Even if they are disassembled for transportation, they cannot be transported underground due to the limited transportation space of the transport vehicle.

[0005] Patent document with application number 201821724261.8 discloses a multifunctional mobile well drilling rig, including a power car assembly, a main engine assembly, a power unit assembly and a drill rod car assembly. The power car assembly is provided with a chassis frame assembly, and the chassis frame assembly includes a chassis frame, a cylinder slide, a pitch cylinder, a driving connecting rod and a pull arm weldment. The chassis frame has a first use state and a second use state. In the first use state, the main engine articulated seat on the chassis frame and the cylinder movable end of the pitch cylinder are connected to the main engine assembly, and the cylinder slide is fixed to the chassis frame. In the second use state, the main engine articulated seat and the cylinder movable end are disconnected from the main engine assembly, the cylinder slide is fixed to the chassis frame, the cylinder movable end is fixed to the cylinder connecting plate, the driving connecting rod movable end is connected to the pull arm weldment, and the pull arm movable end is used to connect the power unit assembly or the drill rod car assembly.

[0006] Compared with traditional drilling rigs, this technical solution can transport the main engine assembly, power unit assembly and drill rod vehicle assembly by itself, but it still has some shortcomings: First, it still transports the power unit assembly and the main engine assembly separately in batches; second, it transports the power unit assembly as a whole by pulling it onto the power vehicle assembly through the chassis frame assembly, and then loading it. Switching between the two usage states of the chassis frame assembly still takes a long time and labor, and the switching efficiency needs to be improved. Summary of the invention

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] The present invention provides a mobile borehole rig with rail wheels and tires that can be quickly switched. Figure 1 In the direction, the side of the chassis frame where the host is provided is defined as the front.

[0041] Please refer to Figures 1 to 10 A mobile shaft drilling rig with rail wheels and tires that can be quickly switched includes: a main machine part 1 and a pump station part 2. The main machine part 1 is arranged on a chassis frame 3. Chassis frame tires 4 and rail wheels 5 are respectively arranged on both sides of the chassis frame 3 along its walking direction. A diesel engine system 6 is arranged on the chassis frame 3 for driving the chassis frame tires 4 to walk; a rail wheel lifting device is also arranged on the chassis frame 3 for lifting the rail wheel 5 to a level higher than the chassis frame tire 4 or lowering it to a level lower than the chassis frame tire 4; the pump station part 2 is provided with a pump station tire 7, and the pump station part 7 is connected to the rear side of the chassis frame 3.

[0042] The present invention arranges the main machine part 1 for drilling work on the chassis frame 3 through a pitch mechanism ( Figure 1 The main machine part 1 is in an open state), a chassis frame tire 4 capable of independently walking on the ground is arranged at the bottom of the chassis frame 3, and a diesel engine system 6 capable of driving the chassis frame tire 4 to independently walk is arranged on the chassis frame 3, and a rail wheel 5 capable of moving on the mine track is also arranged, and the rail wheel 5 is lifted and lowered by a rail wheel lifting device.

[0043] As a result,

[0044] First, when the drilling rig is being transported, the chassis frame tires 4 can be controlled by the self-contained diesel engine system 6 to move, that is, the main machine part 1 can be transported to the mine by itself without the need for another tractor.

[0045] Second, when the mine is equipped with a special slope track for the drilling rig to go down the mine for construction, the main machine part 1 is moved to the track position through the chassis frame tire 4, the rail wheel 5 is located on the inner side of the chassis frame tire 4, and the rail wheel 5 is adjusted through the rail wheel lifting device to lower the rail wheel 5 to below the chassis frame tire 4. The rail wheel 5 contacts and cooperates with the track, and the chassis frame tire 4 and the entire chassis frame 3 are lifted up, and the main machine part 1 can be switched to move through the track; and when the drilling rig needs to be moved on the ground where no track is set, the rail wheel 5 can be controlled to rise, the chassis frame tire 4 contacts the ground again, and the main machine part 1 switches back to walking through the tires, so that the movement of the main machine part 1 is flexible and convenient, so that the drilling rig can adapt to the working needs of mines with different conditions.

[0046] Third, the present invention mechanically connects the pump station part 2 with the chassis frame 3. When the pump station part 2 needs to be moved, it can also be towed and pulled by the chassis frame tires 4. That is, the main machine part 1 and the pump station part 2 can be moved as a whole through the chassis frame tires 4, and they can be moved at one time without the need for an additional tractor or transportation in two times.

[0047] Furthermore, the diesel engine system includes: a diesel engine, a variable dual pump, and a tire drive motor. The diesel engine is drivingly connected to the variable dual pump, the variable dual pump is connected to the tire drive motor, and the tire drive motor is used to drive the chassis frame tire 4 to move.

[0048] For details in this embodiment, please refer to Figure 7-8 The side of the chassis frame 3 facing away from the main engine part 1 is provided with two opposite chassis frame connecting ears, the diesel engine system 6 is provided with a base 61, and one side of the base 61 is protruding with two opposite base connecting ears 62, the two base connecting ears 62 respectively correspond to the two chassis frame connecting ears one by one, and the base connecting ears 62 are connected and fixed to the chassis frame connecting ears by a first pin rod, thereby realizing the detachable connection between the diesel engine system 6 and the chassis frame 3.

[0049] Furthermore, the pump station part 2 includes: a hydraulic oil tank, a reversing multi-way valve group, a diesel engine pump group, a motor pump group and a valve control group. The pump station part 2 is used to provide working power for the drilling work of the main machine part 1, wherein the hydraulic oil tank is used to provide pressure oil, and the valve control group is connected to the diesel engine pump group through the reversing multi-way valve group to control the specific drilling action of the main machine part 1. The motor pump group is used to drive other actuators on the drilling rig.

[0050] In a conventional implementation, the pump station part 2 and the main machine part 1 are separately arranged. After being disassembled and transported to the work site, only the hydraulic pipeline connection is made. When the main machine part 1 is actually working as a drilling rig, according to the location distribution of the drill holes, the pump station part 2 only needs to move once when the main machine part 1 moves several drilling positions.

[0051] Therefore, in this embodiment, the pump station part 2 and the chassis frame 3 are mechanically connected through the traction frame 8, and the connection is detachable, so that when the pump station part 2 needs to be transferred over a long distance or moved a short distance within a mine, the pump station part 2 can be moved through the connection and cooperation between the traction frame 8 and the diesel engine system 6. In some cases, when the pump station part 2 does not need to be moved, the connection between the pump station part 2 and the main machine part 1 can be removed, so that it can be adapted to different work requirements.

[0052] For details, please refer to Fig. 9 The traction frame 8 is triangular in shape, and the two corners of the traction frame 8 are respectively protruded with first connection ears 8-1, and the two first connection ears 8-1 are arranged face to face. The bottom of the front end of the pump station part 2 is provided with a protruding first connection member. When connected with the traction frame 8, the two first connection ears 8-1 of the traction machine 8 can clamp the first connection member. Each first connection ear is fixed to the first connection member by a screw 8-2 and a latch 8-3, and each latch 8-3 is also provided with a cotter pin 8-4 for locking, thereby achieving a fixed connection with the pump station part 2.

[0053] A protruding second connection ear 8-5 is provided at the third angular position of the traction frame 8, the surface where the second connection ear 8-5 is located is horizontally arranged, and a vertically penetrating first through hole 8-6 is provided on the second connection ear 8-5. A protruding second connection member is provided at the bottom of the rear end of the diesel engine system 6, and a vertically penetrating second through hole is provided on the second connection member. When connected with the traction frame 8, the second through hole is aligned with the first through hole 8-6, and the connection is made by inserting a second pin rod, so that there is a certain swing angle between the chassis frame 3 and the pump station part 2.

[0054] Furthermore, the rail wheel lifting device includes: a crankshaft connecting rod mechanism and a driving mechanism. The crankshaft connecting rod mechanism includes a crankshaft 9 and a driving connecting rod 10. The crankshaft 9 is rotatably mounted on the chassis frame 3. The driving connecting rod 10 is mounted on one end of the crankshaft 9 as a rotatable axis. The driving connecting rod 10 extends in the radial direction of the crankshaft 9. The other end of the crankshaft 9 away from the driving connecting rod 10 is mounted on the rail wheel 5. The central axis of the rail wheel 5 is eccentric to the axis of the crankshaft 9. The driving mechanism is used to drive the driving connecting rod 10 to swing back and forth, thereby driving the crankshaft 9 to rotate around its axis. When the crankshaft 9 rotates, the rail wheel 5 is driven to rotate around the axis of the crankshaft 9. The initial position of the rail wheel 5 is: its central axis is on the same horizontal line as the axis of the crankshaft 9. When the crankshaft 9 rotates, it can drive the rail wheel 5 to rise or fall.

[0055] The present invention converts the driving force provided by the driving mechanism into the torque of the crankshaft 9 through the crankshaft connecting rod mechanism, and outputs power through the rotational movement of the crankshaft 9 to make the rail wheel 5 swing up and down, thereby controlling the lifting and lowering of the rail wheel 5. The crankshaft connecting rod mechanism is used for stable transmission and easy control. The rail wheel 5 is made of iron and has a heavy mass, and the crankshaft connecting rod mechanism can withstand a large load, so that the lifting and lowering of the rail wheel 5 are very stable.

[0056] For further information, please refer to Fig. 9 The crankshaft 9 includes: a first end shaft 9-2, a main journal 9-1, a crank arm 9-4, a rail wheel journal 9-3 and a second end shaft 9-5 which are arranged in sequence along the axis direction thereof. The crankshaft 9 is made of one piece. The main journal 9-1 is mounted on the chassis frame 3. The axis of the main journal 9-1 is the axis of the entire crankshaft 9, i.e., the center of rotation. The first end shaft 9-2 is formed at one end of the axial direction of the main journal 9-1, and the first end shaft 9-2 is coaxial with the axis. The first end shaft 9-2 is used to install the driving connecting rod. Therefore, when the driving connecting rod 10 moves, it can drive the crankshaft 9 to rotate. The rail wheel journal 9-3 is eccentrically arranged with the main journal 9-1. The rail wheel journal 9-3 is connected with the main journal 9-1 through the crank arm 9-4, so that when the crankshaft rotates around its axis, the crank arm 9-4 drives the rail wheel 5 to swing up and down.

[0057] Furthermore, two pairs of front and rear rail wheels 5 are provided on the chassis frame 3, and the crankshaft connecting rod mechanism also includes two pairs located at the front and rear respectively. The rail wheel lifting device is also provided with an intermediate connecting rod 11, which is arranged in the middle of the chassis frame. The intermediate connecting rod 11 has a first connecting part 11-1, a second connecting part 11-2 and a third connecting part 11-3. The first connecting part 11-1, the second connecting part 11-2 and the third connecting part 11-3 are respectively located at the three vertices of a triangle. The first connecting part 11-1 is rotatably connected to the two driving connecting rods 10 on the front side, the second connecting part 11-2 is rotatably connected to the two driving connecting rods 10 on the rear side, and the third connecting part 11-3 is used to connect the driving mechanism.

[0058] Therefore, when the driving mechanism is activated and drives the middle connecting rod 11 to move forward and backward, it can simultaneously drive the driving connecting rods 10 of the four crankshaft connecting rod mechanisms to swing forward and backward around the axis of the crankshaft 9, thereby simultaneously driving the two pairs of rail wheels 5 to rise or fall.

[0059] Specifically in the present embodiment, the driving connecting rod 10 at the front side extends upward from the chassis frame 3, and the driving connecting rod 10 at the rear side extends downward from the chassis frame 3. When the driving mechanism is not in operation, the line connecting the rail wheel 5 at the front side to the axis center of the corresponding crankshaft and the line connecting the rail wheel 5 at the rear side to the axis center of the corresponding crankshaft are both in a roughly horizontal position, and the front and rear rail wheels 5 are close to each other.

[0060] When the driving mechanism is activated, the intermediate connecting rod 11 is driven to move backwards. Figure 4-5 , from left to right, the driving link 10 at the front side swings backward clockwise, thereby driving the corresponding rail wheel to swing downward clockwise, and the driving link 10 at the rear side swings backward counterclockwise, thereby driving the corresponding rail wheel to swing downward counterclockwise, and the front and rear pairs of rail wheels are lowered at the same time. When the two pairs of rail wheels 5 are retracted upward, they move closer to each other, and when the two pairs of rail wheels 5 are lowered, they move away from each other, so that when the rail wheels 5 are lowered to support the chassis frame 3, the chassis frame 3 will not move in the horizontal position.

[0061] Furthermore, the driving mechanism includes: a manual pump 12 and a hydraulic cylinder 13. The manual pump 12 and the hydraulic cylinder 13 are arranged on the chassis frame 3, in front of the intermediate connecting rod 11, and the manual pump 12 is connected to the hydraulic cylinder 13 through a hydraulic pipeline, and is used to pump hydraulic oil into the hydraulic cylinder 13. The hydraulic cylinder 13 is located in front of the intermediate connecting rod 11, and the hydraulic cylinder 13 includes a cylinder body and a piston rod, one end of the cylinder body is hinged to the front side of the chassis frame 3, and the other end of the cylinder body has a retractable piston rod, and the piston rod is hinged to the third connecting portion 11-3 of the intermediate connecting rod 11.

[0062] Therefore, when the piston rod of the control hydraulic oil cylinder 13 is extended, the piston rod pushes the middle connecting rod 11 to move backward as a whole, so that the first connecting part 11-1 of the middle connecting rod 11 drives the pair of crankshafts 9 located at the front side to rotate through the corresponding driving connecting rod 10, and the second connecting part 11-2 also drives the pair of crankshafts 9 located at the rear side to rotate through the corresponding driving connecting rod 10, and the two pairs of crankshafts 9 then respectively lower the rail wheels 5. When the piston rod of the control hydraulic oil cylinder 13 is retracted, the piston rod pulls the middle connecting rod 11 forward as a whole, so that the middle connecting rod 11 simultaneously drives the two pairs of crankshafts 9 to rotate in the opposite direction, and the two pairs of rail wheels 5 are lifted and retracted.

[0063] Furthermore, the first connecting part 11-1 and the second connecting part 11-2 are both provided with a first mounting hole, and a second mounting hole is provided on the end of the driving connecting rod 10 away from the crankshaft 9. The first connecting part 11-1 or the second connecting part 11-2 is clamped between the two opposite driving connecting rods 10 and connected by a copper sleeve and an expansion pin.

[0064] The advantage of using a copper sleeve and an expansion pin for connection is that the inner diameters of the first mounting hole on the intermediate connecting rod 11 and the second mounting hole on the driving connecting rod 10 are likely to be out of round during processing. If an ordinary connecting shaft is used for connection, there may be a movable gap or the connecting shaft may be unable to be inserted. Therefore, in this embodiment, an expansion pin is used to connect the intermediate connecting rod 11 and the driving connecting rod 10. The radial dimension of the expansion pin can be adjusted to solve the problem of inaccurate positioning and improve the installation and positioning accuracy of the intermediate connecting rod 11 and the two pairs of driving connecting rods 10.

[0065] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
