Description

Technical Field

[0001] The utility model relates to the manufacturing and application fields of coal mine roadway support equipment, in particular to a 1.1-meter-wide narrow-body bolt and cable drill jumbo. Background Art

[0002] At present, in the support operation of small-section roadways, the vast majority still adopt the traditional operation mode of manually holding tools, which has serious problems such as a large number of workers, low efficiency, poor safety, and high labor intensity of workers. Moreover, the small-section roadway restricts mechanized operation, and it is difficult for conventional support operation equipment to enter. Only a very small number of coal mines use bolt drill jumbos for support operations, and the operation is relatively complex and the support efficiency is not high. Therefore, the existing coal mine roadway support equipment still has limitations, and there is an urgent need to develop a support equipment suitable for small-section coal mine roadways.

[0003] Based on this, the present application creates a 1.1-meter-wide narrow-body bolt and cable drill jumbo. The drill jumbo has a compact body, and the width of the vehicle body does not exceed 1.1 meters when retracted, which is suitable for small-section roadway operations. It will comprehensively improve in terms of reducing the number of workers, improving efficiency, reducing labor intensity, and enhancing safety, and is the preferred equipment for the mechanization of coal mine underground roadway support operations. Summary of the Utility Model

[0005] To solve the above technical problem, the utility model provides a 1.1-meter-wide narrow-body bolt and cable drill jumbo, including a main body part, a traveling part arranged below it, a drill arm mechanism and a drilling mechanism arranged above the main body part. A drill arm transverse movement mechanism is also arranged on the main body part. The drill arm transverse movement mechanism includes a transverse movement sliding box part, a mounting seat group and a transverse movement oil cylinder group. The mounting seat group is fixedly installed in the middle above the main body part. The fixed end of the transverse movement oil cylinder group is connected to the mounting seat group, and its extending end is connected to the transverse movement sliding box part. The transverse movement oil cylinders inside the transverse movement oil cylinder group extend and retract to drive the transverse movement sliding box part to extend and retract perpendicular to the traveling direction of the main body part.

[0006] One end of the drill arm mechanism is connected to the transverse movement sliding box part, and the other end is connected to the drilling mechanism. Then, the drilling mechanism realizes multi-angle adjustment in the left-right, up-down, and front-back directions under the action of the drill arm transverse movement mechanism and the drill arm mechanism.

[0007] For further improvement, two symmetrically arranged drill arm transverse movement mechanisms are provided on the body part. The transverse sliding boxes of the two drill arm transverse movement mechanisms extend out and retract towards the left and right sides of the body part respectively, and the drill arm mechanisms are respectively connected to the two transverse sliding boxes.

[0008] For further improvement, when both of the two drill arm transverse movement mechanisms are retracted, the width is 1.1 meters, and when both of the two drill arm transverse movement mechanisms are extended, the width is 1.5 meters.

[0009] For further improvement, the drill arm mechanism includes a drill arm rotation group, a drill arm support group, a drill arm telescopic group and a drill arm leveling group. The drill arm rotation group drives the drill arm telescopic group to rotate left and right relative to the transverse sliding box part. The drill arm support group drives the drill arm telescopic group to swing up and down. The inner sleeve of the drill arm telescopic group expands and contracts relative to the outer sleeve under the action of its telescopic oil cylinder. The drill arm leveling group is arranged at the outer end of the inner sleeve of the drill arm telescopic group, and the drilling mechanism is arranged on the drill arm leveling group.

The inner sleeve of the lifting support group expands and contracts under the action of its support lifting oil cylinder. The bottom of the top plate telescopic group is rotatably connected to the top end of the inner sleeve of the lifting support group. The top of the top plate telescopic group adopts a top plate group that can expand and contract left and right. Then, the top plate group realizes the adjustment of the front and rear, up and down, left and right positions and angles under the action of the front and rear telescopic group, lifting support group and top plate telescopic group. The inner leg of the leg telescopic group is supported on the ground or retracted downward under the action of its leg oil cylinder.

One end of the fixing part of the folding support leg group is fixed to the rear of the body part, and the other end of the fixing part of the folding support leg group is hinged to one end of the moving part of the folding support leg group. The other end of the moving part of the folding support leg group rotates under the action of the telescopic oil cylinder of the first telescopic oil cylinder group to realize the ground-supporting action of the rear support.

[0014] For further improvement, the traveling part adopts a left-right telescopic traveling part, which includes a tensioning wheel group, a crawler chain, a crawler beam, a second telescopic oil cylinder group, a guide rod group, an intermediate beam, and a driving wheel group;

[0015] One crawler beam is provided on each side of the intermediate beam. The tensioning wheel group and the driving wheel group are respectively provided at both ends of the crawler beam.

In the driving wheel group, the motor and the reducer cooperate to provide power, so that the crawler chain rotates synchronously with the driving wheel group and the tensioning wheel group;

[0016] A second telescopic oil cylinder group is provided in the middle of the intermediate beam. The second telescopic oil cylinder group includes two telescopic oil cylinders arranged back to back. The extending ends of the two telescopic oil cylinders are respectively connected to the two crawler beams. A guide rod group parallel to the second telescopic oil cylinder group is also provided on the intermediate beam. When the inner legs of the front support mechanism and the folding support leg group of the rear support both complete the ground-supporting action downward and lift the drill jumbo, the second telescopic oil cylinder group extends to increase the width of the drill jumbo.

[0017] For further improvement, an oil tank part, a motor oil pump part, and a cover plate part are provided above the rear of the body part. A retractable walking pedal is provided at the rear end of the cover plate part.

[0018] For further improvement, it further includes an electrical system for providing signals to each executing component of the drill jumbo, a hydraulic system for providing hydraulic power to each executing component of the drill jumbo, and a waterway system for supplying water to each executing component of the drill jumbo.

[0041] In order to realize mechanized operations such as bolt and cable anchor support in narrow and small-section roadways for a jumbo, ensure the safety of operators, improve work efficiency and reduce labor intensity, this embodiment provides a 1.1-meter-wide hydraulic bolt drill jumbo for coal mines. The specific embodiments are as follows.

[0042] Refer to Figure 1 and 2 As shown, the 1.1-meter-wide hydraulic bolt drill jumbo for coal mines in this embodiment includes a drilling mechanism 1, an operation platform 2, a drill arm mechanism 3, a drill arm transverse movement mechanism 4, a cover plate part 5, a rear support 6, a motor oil pump part 7, a telescopic walking part 8, an oil tank part 9, a body part 10, a front support mechanism 11 and a man-standing platform 12, as well as an electrical system, a hydraulic system and a waterway system.

[0043] Among them, the drill arm transverse movement mechanism 4, the cover plate part 5, the rear support 6, the motor oil pump part 7, the telescopic walking part 8, the oil tank part 9, and the front support mechanism 11 are all connected to the body part 10; the drill arm transverse movement mechanism 4 is connected to the middle part above the body part 10 and can move horizontally left and right along the body part 10; the telescopic walking part 8 is connected to the bottom plane of the body part 10 and can stretch left and right along the body part 10; the front support mechanism 11 is connected to the front part above the body part 10 and can move back and forth along the body part 10; the oil tank part 9, the cover plate part 5, the motor oil pump part 7, and the rear support 6 are connected to the rear part of the body part 10. One end of the drill arm mechanism 3 is rotatably connected to the drill arm transverse movement mechanism 4, and the other end is connected to the drilling mechanism 1, the operation platform 2 and the man-standing platform 12. The width of the drill jumbo in the retracted state is 1.1 meters, which is convenient for the drill jumbo to walk in narrow and small-section roadways and for passing each other in the roadway. In the state where the drill arm transverse movement mechanism 4 and the telescopic walking part 8 are extended, the width of the drill jumbo can reach 1.5 meters, which is convenient for the drill jumbo to perform drilling operations and is stable and reliable.

[0044] Specifically, as Figure 3As shown in the figure, in this embodiment, the drilling arm transverse movement mechanism 4 includes a transverse movement slide box part 4-1, a mounting seat group 4-2, and a transverse movement oil cylinder group 4-3. The mounting seat group 4-2 is installed above the middle position of the main body part 10 by bolts. The fixed end of the transverse movement oil cylinder group 4-3 is installed on the mounting seat group 4-2 through a pin shaft and a baffle plate, and its extending end is installed on the transverse movement slide box part 4-1 through a pin shaft and a baffle plate. Driven by the telescopic movement of the internal transverse movement oil cylinders in the transverse movement oil cylinder group 4-3, the transverse movement slide box part 4-1 can extend and retract perpendicular to the traveling direction of the main body part 10, thereby driving the drilling arm mechanism 3 thereon to extend and retract.

[0045] Preferably, two symmetrically arranged drilling arm transverse movement mechanisms 4 are provided on the main body part 10. The two drilling arm transverse movement mechanisms 4 share a mounting seat group 4-2, and the two transverse movement slide box parts 4-1 extend and retract to the left or right side of the main body part 10 respectively.

[0046] Refer to again Figure 4As shown in the figure, the drill arm mechanism 3 includes a drill arm slewing group 3-1, a drill arm support group 3-2, a drill arm telescopic group 3-3, and a drill arm leveling group 3-4. The slewing base of the drill arm slewing group 3-1 is installed on the transverse sliding box part 4-1 through a pin shaft and a retaining plate. The left and right transverse movement of the transverse sliding box part 4-1 can drive the drill arm to move left and right synchronously. When the slewing oil cylinder of the drill arm slewing group 3-1 extends, it drives the slewing base to rotate outward. When the slewing oil cylinder retracts, it drives the slewing base to retract to its original position, that is, the drill arm slewing group 3-1 drives the drill arm telescopic group 3-3 to swing left and right relative to the transverse sliding box part 4-1. The outer sleeve of the drill arm telescopic group 3-3 is installed on the slewing base through a pin shaft and a retaining plate. The fixed end of the telescopic oil cylinder in the drill arm telescopic group 3-3 is connected to the outer sleeve through a pin shaft, and the movable end of its telescopic oil cylinder is connected to the inner sleeve of the drill arm telescopic group 3-3 through a pin shaft. The telescopic oil cylinder can realize the extension and retraction of the inner sleeve of the drill arm telescopic group 3-3 through telescopic action, that is, realize the elongation and shortening of the drill arm telescopic group 3-3, and further drive the drilling mechanism 1 to move back and forth. The fixed end of the oil cylinder of the drill arm support group 3-2 is connected to the slewing base through a pin shaft, and the movable end of its oil cylinder is connected to the outer sleeve of the drill arm telescopic group 3-3 through a pin shaft. When the oil cylinder of the drill arm support group 3-2 extends, it drives the drill arm telescopic group 3-3 to lift upward. When the oil cylinder retracts, it drives the drill arm telescopic group 3-3 to retract to its original position, that is, the drill arm support group 3-2 drives the drill arm telescopic group 3-3 to swing up and down. The drill arm leveling group 3-4 is connected to the outer end of the inner sleeve of the drill arm telescopic group 3-3 through bolts. The drilling mechanism 1 is arranged on the drill arm leveling group 3-4. The operator platform 12 and the operation platform 2 are arranged on the side of the drill arm leveling group 3-4. Then, adjusting the extension stroke of the telescopic oil cylinder in the drill arm leveling group 3-4 can realize the adjustment of the use angle of the operation platform 2 and the operator platform 12. Adjusting the two swing oil cylinders in the drill arm leveling group 3-4 can rotate by 0-180°, and can realize the adjustment of the use angle of the drilling mechanism 1. Based on the structures of the drill arm mechanism 3 and the drill arm transverse movement mechanism 4, the drilling mechanism 1 can realize multi-angle all-round adjustment under the action of the drill arm slewing group 3-1, the drill arm support group 3-2, the drill arm telescopic group 3-3, and the drill arm leveling group 3-4, better meeting the drilling requirements.

[0047] In this embodiment, the operator platform 12 adopts a folding and telescopic platform structure. When in use, it is unfolded for the operator to stand on, simply and conveniently realizing the operation of the operator on the operation platform 2. When not in use, it is folded and retracted, reducing the usage area of the drill truck. And the operator platform 12 is arranged on the drill arm mechanism 3 and can move with the drill arm mechanism 3, which is more conducive to the convenience and safety of operation.

[0048] Refer to Figure 5As shown in the figure, in this embodiment, the front support mechanism 11 includes a top plate telescopic group 11-1, a lifting support group 11-2, a front-back telescopic group 11-3, and a leg telescopic group 11-4. The outer cylinder of the front-back telescopic group 11-3 is installed above the front part of the main body 10 by bolts. The inner cylinder of the front-back telescopic group 11-3 is connected to the outer cylinder of the leg telescopic group 11-4 by bolts. The leg telescopic group 11-4 can move back and forth along the main body 10 under the action of the telescopic oil cylinder built in the front-back telescopic group 11-3. The fixed end of the leg oil cylinder inside the outer cylinder of the leg telescopic group 11-4 is connected to the top of the outer cylinder by bolts, and the movable end of its leg oil cylinder extends out to support the ground, playing a role in stabilizing the vehicle body or lifting the drill rig. The outer cylinder of the lifting support group 11-2 is connected to the outer cylinder of the leg telescopic group 11-4 by bolts. The fixed end of the built-in support lifting oil cylinder is connected to its outer cylinder by a pin shaft, and the movable end of the support lifting oil cylinder is connected to the inner cylinder of the lifting support group 11-2 by a pin shaft. When the support lifting oil cylinder extends, it drives the lifting support group 11-2 to extend upward, and when the support lifting oil cylinder retracts, it drives the lifting support group 11-2 to retract downward to the original position. The mounting seat at the bottom of the top plate telescopic group 11-1 is connected to the inner cylinder of the lifting support group 11-2 by a pin shaft, and can rotate left and right within a certain range along with the pin shaft to adjust the angle of the top plate group to meet the angle requirements of the roadway top. The fixed end of the telescopic oil cylinder of the top plate telescopic group 11-1 is connected to the bottom mounting seat by a pin shaft and a retaining piece, and the movable end of its telescopic oil cylinder is connected to the top plate group by a pin shaft and a retaining piece. When the telescopic oil cylinder extends, it drives the top plate group to horizontally extend left and right to increase the support range, and when the telescopic oil cylinder retracts, it drives the top plate group to retract to the original position to reduce the width of the front support mechanism 11. Then, the top plate group realizes the adjustment of the front-back, up-down, left-right positions and the angle under the action of the front-back telescopic group 11-3, the lifting support group 11-2, and the top plate telescopic group 11-1. The inner legs of the leg telescopic group 11-4 support the ground downward or retract under the action of its leg oil cylinder, playing a role in stabilizing the vehicle body or lifting the drill rig.

The folding support leg group 6-2 is connected to the rear part of the main body 10 by bolts. One end of the fixing part of the folding support leg group 6-2 is fixed to the lower part of the rear part of the main body 10 by a pin shaft and a retaining piece, and the other end of this fixing part is hinged to one end of the moving part of the folding support leg group 6-2. The other end of the moving part of the folding support leg group 6-2 rotates under the action of the telescopic oil cylinder of the first telescopic oil cylinder group 6-1 to realize the ground-supporting action of the rear support 6, playing a role in stabilizing the drill rig and lifting the drill rig.

[0050] Referring to Figure 7As shown in the figure, in this embodiment, the telescopic walking part 8 includes a tensioning wheel set 8-1, a crawler chain 8-2, a crawler beam 8-3, a second telescopic oil cylinder set 8-4, a guide rod set 8-5, an intermediate beam 8-6, and a driving wheel set 8-7.

[0051] On both sides of the intermediate beam 8-6, there is respectively a crawler beam 8-3. At both ends of the crawler beam 8-3, there are respectively the tensioning wheel set 8-1 and the driving wheel set 8-7. In the tensioning wheel set 8-1, the tensioning oil cylinder is installed inside the crawler beam 8-3 to provide thrust for tensioning the crawler chain 8-2. The crawler chain 8-2 is installed outside the tensioning wheel set 8-1 and the driving wheel set 8-7 through gear meshing. In the driving wheel set 8-7, the motor and the reducer cooperate to provide power, so that the crawler chain 8-2 rotates synchronously with the driving wheel set 8-7 and the tensioning wheel set 8-1.

[0052] In the middle of the intermediate beam 8-6, there is a second telescopic oil cylinder set 8-4. The second telescopic oil cylinder set 8-4 includes two telescopic oil cylinders arranged back to back. The extending ends of the two telescopic oil cylinders are respectively connected to the two crawler beams 8-3. On the intermediate beam 8-6, there are also two guide rod sets 8-5 parallel to the second telescopic oil cylinder set 8-4. When the inner legs of the front support mechanism 11 and the folding support leg group 6-2 of the rear support 6 both complete the downward grounding action and lift the drill rig, the extending ends of the second telescopic oil cylinder set 8-4 extend, and the two crawler beams 8-3 move and extend along the guide rods of the guide rod set 8-5 to complete the increase in the width of the drill rig.

In a preferred embodiment, a retractable walking pedal 5-1 is provided at the rear of the cover plate part 5. When the drill rig needs to be manually operated to walk, the walking pedal 5-1 is pulled out for the operator to stand on, which is convenient for operating the operation buttons on the upper part of the cover plate part. When manual operation is not required, the walking pedal 5-1 can be retracted without affecting the use of the drill rig.

[0054] Moreover, the bolt and cable drill rig in this embodiment further includes an electrical system for providing signals to each executing component of the drill rig, a hydraulic system for providing hydraulic power to each executing component of the drill rig, and a waterway system for supplying water to each executing component of the drill rig.
