Description

Technical Field

[0001] The present invention belongs to the field of crawler transportation equipment, and particularly relates to a multi-functional crawler transport vehicle. Background Art

[0002] There is a large amount of material transportation work in coal mining. Generally, a manual push trolley is used to transport materials, accessories and other items on the coal mine to the coal mine roadway, and the reciprocating turnover is used to achieve the purpose. However, this method has low efficiency and high labor intensity. Therefore, mechanical transport vehicles are generally used to transport materials in batches.

[0003] The current mechanized transport equipment on the market has a single function. Facing the special ground environment of coal mines, the rubber wheels used during walking often malfunction and are damaged, and the working stability is poor. At the same time, it does not have the ability to hoist large materials, and large materials still need to be manually loaded onto the vehicle, making transportation difficult. There are often a lot of coal cinders remaining on the ground of the coal mine roadway, which hinders the walking of the transport vehicle, and it is inconvenient for workers to clean up at any time. For the self-unloading transport equipment used, when unloading, the vehicle is prone to tilting of the front end due to the weight difference between the front and rear ends, resulting in low safety.

[0004] Therefore, in view of the above situation of large labor intensity, low efficiency and potential safety hazards in transporting materials and sundries on coal mines, a new type of transport vehicle is developed. The crawler walking mechanism is used to improve the walking stability in complex ground environments, and it is equipped with a shovel and a support mechanism on the vehicle body to facilitate the cleaning of ground coal cinders, and the safety is also higher when unloading. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a multi-functional crawler transport vehicle, which aims to solve the technical problems of low efficiency and poor safety of the existing mechanical equipment used in current coal mining.

[0007] (2) Technical Solutions

[0008] To solve the above technical problems, the present invention provides such a multifunctional crawler transporter, which includes crawler transmission mechanisms symmetrically arranged on the left and right, a vehicle head arranged on one side of the front end of the crawler transmission mechanism, a carriage arranged above the crawler transmission mechanism, a front push shovel mechanism installed at the lower end of the vehicle head, and a rear support mechanism arranged at the rear side of the crawler transmission mechanism. A balance platform is installed between the crawler transmission mechanisms, and a power unit for driving the crawler transmission mechanisms to move is installed inside the balance platform. The vehicle head and the carriage are both installed at the upper end of the balance platform. A hoisting mechanism and a balance mechanism are arranged between the vehicle head and the carriage, and the hoisting mechanism is installed at the upper end of the balance mechanism. Two groups of the rear support mechanisms are symmetrically arranged on the left and right. A support is arranged in the groove at the rear end of the rear support mechanism. A first shaft column is movably connected between the support and the rear support mechanism. A movable sleeve is installed in the groove at the rear end of the support, a backing plate is installed at the lower end of the movable sleeve, and a second shaft column is movably connected between the inner side of the movable sleeve and the support. A suspension beam is arranged on the side of the front push shovel mechanism close to the crawler transmission mechanism, a shovel blade is arranged on the side of the front push shovel mechanism far from the crawler transmission mechanism, a movable shaft is fixedly connected to one end of the shovel blade close to the suspension beam, the movable shaft is movably connected to the inside of the suspension beam, a guide rail is arranged in parallel on the side of the suspension beam close to the crawler transmission mechanism, and a linear motor is installed between the suspension beam and the guide rail.

[0009] When using a multi-functional crawler transporter with this technical solution, the user drives the transporter and walks in the coal mine roadway through the crawler drive mechanism. Along the way, it stops at the material loading point, then activates the balance mechanism. By driving the built-in horizontal oil cylinder, the balance arm extends outward. Then, the vertical oil cylinder is activated to move the support leg downward until the enlarged end at the bottom of the support leg closely adheres to the ground, lifting the vehicle body to achieve the effect of stabilizing the vehicle body. Then, the hoisting mechanism is activated to horizontally rotate the turntable, so that the primary jib originally above the carriage rotates to the side of the carriage. The secondary jib is pushed outwards through the hydraulic mechanism inside the primary jib. Then, the pulley block on the jib is controlled to rotate, driving the cable to descend, hanging the material on the hanging ring. Then, the material is lifted in the reverse direction, and at the same time, the turntable is rotated to make the material reach above the carriage, and the material is lowered into the carriage. Then, the hanging ring is untied, the hoisting mechanism is reset and shut down. Subsequently, the balance mechanism is retracted, and the user continues to drive the transporter to move. The steering motor is activated to control the movable shaft and the shovel to rotate downward until the bottom surface of the shovel closely adheres to the ground surface. During the walking process, the shovel shovels up and clears the residual coal cinder on the ground. The coal cinder at the edge of the roadway is cleared by activating the linear motor to drive the shovel to move horizontally left and right, closely adhering to the corner position of the roadway to facilitate the clearing of the coal cinder at the edge. When reaching the designated unloading location, the second diagonal pulling oil cylinder is activated to push the support seat to rotate downward along the first shaft column until the backing plate supports on the ground, playing a role in supporting and stabilizing the tail of the transporter. Then, through the hydraulic unit in the opening and closing mechanism, the claw is horizontally pushed to move away from the door panel, unlocking the door panel. The first diagonal pulling oil cylinder is activated to push the carriage upward, and the carriage rotates and tilts upward with the central axis seat as the axis, and the material pours outwards from the door panel.

[0010] Further, the balance mechanism includes two groups of horizontal oil cylinders installed inside, balance arms movably connected to the left and right ends of the balance mechanism. The balance arms are installed on the hydraulic output components of the horizontal oil cylinders. The horizontal oil cylinders in the balance mechanism simultaneously extend the hydraulic actuators to the left and right sides, pushing the balance arms out and unfolding them from the hollow balance mechanism, forming a longer lever arm in cooperation with the balance mechanism to improve the anti-overturning ability of the transporter.

[0011] Further, a vertical oil cylinder is installed at the back end of the balance arm. A longitudinally telescopic cylindrical support leg is installed on the hydraulic output component of the vertical oil cylinder. The enlarged surface at the lower end of the support leg supports on the ground surface. The vertical oil cylinder controls the support leg to extend downward, making the enlarged disc-shaped structure at its bottom closely adhere to the ground. Using the reverse force of the ground to lift the vehicle, the stability of the vehicle when hoisting materials is improved through two-point support.

[0012] Furthermore, the hoisting mechanism includes a turntable driven by a motor to perform horizontal circular motion, a primary boom installed at the upper end of the turntable, a horizontal hydraulic cylinder installed inside the primary boom, and a secondary boom movably connected to the inner side of the primary boom. The secondary boom is installed on the hydraulic output element of the horizontal hydraulic cylinder. The bottom of the hoisting mechanism has a driving motor, and the turntable is installed on the output element of the driving motor. The angle and direction of the hoisted material are adjusted by horizontal rotation.

[0013] Furthermore, a cable is provided at the top end of the secondary boom and is hoisted and lowered by a motor and a pulley block mechanism. A hanging ring with a spring locking mechanism is installed at the bottom end of the cable. It is the same as the cable mechanism of existing crane equipment. The pulley block mechanism is driven by a motor installed on the hoisting mechanism. The cable is lowered or retracted by the rotation of the pulley, so that the hanging ring approaches the material. There is a spring latch at the notch of the hanging ring, which can be self-closed to prevent the material from slipping off.

[0014] Furthermore, an opening and closing mechanism is installed at the bottom end of the carriage. The opening and closing mechanism includes a built-in hydraulic cylinder. Claws are symmetrically arranged on the left and right at the rear end of the carriage. The claws are connected to the power output element of the opening and closing mechanism. A door panel is hinged to the rear end of the carriage. The opening and closing mechanism has a built-in hydraulic cylinder. The horizontal telescopic hydraulic actuator controls the claws to move away from or close to one side of the carriage. When the material slides down naturally, the door panel is opened by the impact force.

[0015] Furthermore, a first diagonal pulling hydraulic cylinder is installed at the upper end of the balance platform. The bottom end of the carriage is connected to the hydraulic actuator of the first diagonal pulling hydraulic cylinder through a universal joint. A central shaft seat is movably connected between the carriage and the balance platform. The central shaft seat is arranged on the right side of the first diagonal pulling hydraulic cylinder. The first diagonal pulling hydraulic cylinder extends the hydraulic shaft rod obliquely upward, pushing the carriage to move upward. At the same time, the universal joint rotates at a certain angle, so that the hydraulic shaft rod can accurately apply a pushing force. The bottom of the carriage is also movably connected to the balance platform through the central shaft seat, and the carriage tilts upward with the central shaft seat as the axis.

[0016] Furthermore, a second diagonal pulling hydraulic cylinder is installed at the upper end of the rear support mechanism. A connecting seat is installed at the upper end of the support. The connecting seat is movably connected to the hydraulic actuator of the second diagonal pulling hydraulic cylinder. The second diagonal pulling hydraulic cylinder extends the hydraulic shaft rod obliquely downward, pushing the support to turn downward with the first shaft column as the axis, so that the backing plate approaches the ground. As the support turns, the movable sleeve rotates along the second shaft column by its own gravity, so that the bottom surface of the backing plate is parallel to the ground.

[0017] Further, a steering motor is installed at the lower end of the vehicle head. One end of the movable shaft is fixedly installed on the power output element of the steering motor. Hanging rods are installed between the upper left and right sides of the upper end of the guide rail and the lower end of the vehicle head. The power output element of the steering motor drives the movable shaft to make a circular motion, causing the shovel to rotate slightly. When its bottom is close to the ground after rotation, it shovels up the cinder on the ground during the walking process.

[0018] Further, a chute is axially opened at the upper end of the suspension beam, and a sliding rod is fixedly connected to the lower end of the vehicle head. The lower end of the sliding rod is movably connected to the inner side of the chute. When the suspension beam drives left and right by a linear motor, through the movable connection between the chute and the sliding rod, it stably moves left and right horizontally, and firmly fixes the suspension beam to the lower end of the vehicle head through the sliding rod, ensuring that the end of the shovel is perpendicular to both sides of the roadway.

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: A multi-functional tracked transport vehicle of the present invention is a transport vehicle that travels on tracks and can move in a relatively complex geographical environment. With a hoisting mechanism with a telescopic hoisting arm, it can realize the loading and unloading functions of large materials. The transport vehicle is equipped with a front push shovel, which can realize the functions of road surface leveling and obstacle clearing. The carriage has a self-unloading function, which can realize the automatic loading and unloading of materials. With an automatically supported rear support mechanism, it can prevent the vehicle head from tilting due to uneven weight during self-unloading, with high safety, realizing the integrated functions of material transportation, loading and unloading, and road surface cleaning and leveling, reducing the labor intensity of workers and improving work efficiency.

A balance platform 2 is installed between the crawler transmission mechanisms 1, and a power unit for driving the crawler transmission mechanisms 1 to travel is installed inside the balance platform 2. Both the vehicle head 3 and the carriage 4 are installed at the upper end of the balance platform 2. A hoisting mechanism 5 and a balance mechanism 6 are arranged between the vehicle head 3 and the carriage 4. The hoisting mechanism 5 is installed at the upper end of the balance mechanism 6. There are two groups of the rear support mechanisms 8 arranged symmetrically on the left and right. A support 9 is arranged in the groove at the rear end of the rear support mechanism 8. A first shaft column 10 is movably connected between the support 9 and the rear support mechanism 8. A movable sleeve 11 is installed in the groove at the rear end of the support 9. A backing plate 12 is installed at the lower end of the movable sleeve 11. A second shaft column 13 is movably connected between the inner side of the movable sleeve 11 and the support 9. A suspension beam 14 is arranged on one side of the front push shovel mechanism 7 close to the crawler transmission mechanism 1. A shovel blade 16 is arranged on the side of the front push shovel mechanism 7 away from the crawler transmission mechanism 1. One end of the shovel blade 16 close to the suspension beam 14 is fixedly connected with a movable shaft 15. The movable shaft 15 is movably connected to the inside of the suspension beam 14. A guide rail 17 is arranged in parallel on one side of the suspension beam 14 close to the crawler transmission mechanism 1. A linear motor 18 is installed between the suspension beam 14 and the guide rail 17.

[0029] For this specific embodiment, the linear motor 18 directly converts electrical energy into linear motion mechanical energy. The guide rail 17 is a magnetic track fixed with magnets. The mover of the linear motor 18 includes a coil winding, a Hall element circuit board, a thermal regulator, and an electronic interface. The position of the mover in the magnetic field generated by the magnetic track is maintained by the guide rail 17. The position of the linear motor 18 is fed back through a linear encoder. The magnetic force pushes the linear motor 18 to move axially along the guide rail 17, driving the shovel blade 16 to move horizontally left and right to clean the scattered coal materials at the corner positions of the roadway.

[0030] Among them, the balance mechanism 6 includes two groups of horizontal oil cylinders installed inside, balance arms 19 movably connected to the left and right ends of the balance mechanism 6. The balance arms 19 are installed on the hydraulic output elements of the horizontal oil cylinders. A vertical oil cylinder 20 is installed at the back of one end of the balance arm 19. A longitudinally telescopic cylindrical support leg 21 is installed on the hydraulic output element of the vertical oil cylinder 20. The enlarged surface at the lower end of the support leg 21 supports on the ground surface. The hoisting mechanism 5 includes a turntable 22 driven by a motor to perform horizontal circular motion, a first-stage boom 23 installed at the upper end of the turntable 22, a horizontal oil cylinder installed inside the first-stage boom 23, a second-stage boom 24 movably connected to the inner side of the first-stage boom 23. The second-stage boom 24 is installed on the hydraulic output element of the horizontal oil cylinder. A cable 25 driven by a motor and a pulley block mechanism to lift and lower is arranged at the top of the second-stage boom 24. A hanging ring 26 with a spring locking mechanism is installed at the bottom end of the cable 25. The horizontal oil cylinders in the balance mechanism 6 simultaneously extend the hydraulic actuators to both the left and right sides, pushing the balance arms 19 out of the hollow balance mechanism 6 and stretching them out, cooperating with the balance mechanism 6 to form a longer lever arm, improving the anti-overturning ability of the transport vehicle. The vertical oil cylinder 20 controls the support leg 21 to extend downward, making the enlarged disc-shaped structure at its bottom closely adhere to the ground, using the reaction force of the ground to lift the vehicle, and improving the stability of the vehicle when hoisting materials through two-point support. The bottom of the hoisting mechanism 5 has a driving motor, and the turntable 22 is installed on the output element of the driving motor, adjusting the angle and direction of the hoisted material through horizontal rotation. Similar to the cable mechanism of the existing crane equipment, the pulley block mechanism is driven by a motor arranged on the hoisting mechanism 5. By rotating the pulley, the cable 25 is lowered or retracted, making the hanging ring 26 approach the material. There is a spring lock at the notch of the hanging ring 26, which can be self-closed to prevent the material from slipping off.

[0031] Meanwhile, an opening and closing mechanism 27 is installed at the bottom end of the carriage 4. The opening and closing mechanism 27 includes a built-in hydraulic cylinder. Claws 28 are symmetrically arranged on the left and right at the rear end of the carriage 4. The claws 28 are connected to the power output element of the opening and closing mechanism 27. A door panel 29 is hinged to the rear end of the carriage 4. A first diagonal pulling oil cylinder 30 is installed at the upper end of the balance platform 2. The bottom end of the carriage 4 is connected to the hydraulic execution element of the first diagonal pulling oil cylinder 30 through a universal joint. A middle shaft seat 31 is movably connected between the carriage 4 and the balance platform 2. The middle shaft seat 31 is arranged on the right side of the first diagonal pulling oil cylinder 30. A second diagonal pulling oil cylinder 32 is installed at the upper end of the rear support mechanism 8. A connecting seat 33 is installed at the upper end of the support 9. The connecting seat 33 is movably connected to the hydraulic execution element of the second diagonal pulling oil cylinder 32. The opening and closing mechanism 27 has a built-in hydraulic cylinder. The horizontal telescopic hydraulic execution element controls the claws 28 to move away from or close to one side of the carriage 4. When the material slides down naturally, the impact force opens the door panel 29. The first diagonal pulling oil cylinder 30 extends the hydraulic shaft rod obliquely upward, pushing the carriage 4 to move upward. At the same time, the universal joint rotates at a certain angle, enabling the hydraulic shaft rod to accurately apply the pushing force. The bottom of the carriage 4 is also movably connected to the balance platform 2 through the middle shaft seat 31. The carriage 4 tilts upward with the middle shaft seat 31 as the axis. The second diagonal pulling oil cylinder 32 extends the hydraulic shaft rod obliquely downward, pushing the support 9 to tilt downward with the first shaft column 10 as the axis, making the backing plate 12 approach the ground. As the support 9 tilts, the movable sleeve 11 rotates along the second shaft column 13 by its own gravity, making the bottom surface of the backing plate 12 parallel to the ground.

[0032] In addition, a steering motor 34 is installed at the lower end of the vehicle head 3. One end of the movable shaft 15 is fixedly installed on the power output element of the steering motor 34. Hanging rods 35 are installed between the upper ends of the left and right sides of the guide rail 17 and the lower end of the vehicle head 3. A chute 36 is axially opened at the upper end of the suspension beam 14. The lower end of the vehicle head 3 is fixedly connected to a sliding rod 37. The lower end of the sliding rod 37 is movably connected to the inner side of the chute 36. The power output element of the steering motor 34 drives the movable shaft 15 to make a circular motion, causing the shovel 16 to rotate slightly. When its bottom closely adheres to the ground after rotation, it shovels up the cinder on the ground during the walking process. When the suspension beam 14 drives the left and right movement through the linear motor 18, through the movable connection between the chute 36 and the sliding rod 37, it stably moves horizontally left and right, and firmly fixes the suspension beam 14 to the lower end of the vehicle head 3 through the sliding rod 37, ensuring that the end of the shovel 16 is perpendicular to both sides of the roadway.

[0033] When using a multifunctional crawler transporter adopting the present technical solution, the user drives the transporter to travel in the coal mine roadway through the crawler transmission mechanism 1. Along the way, the transporter stops at the material loading point, and then activates the balance mechanism 6. The balance arm 19 is driven by the built-in horizontal oil cylinder to extend outwards. Then, the vertical oil cylinder 20 is activated to move the support leg 21 downwards until the enlarged end at the bottom of the support leg 21 closely adheres to the ground, lifting the vehicle body to achieve the effect of stabilizing the vehicle body. Then, the hoisting mechanism 5 is activated to horizontally rotate the turntable 22, so that the primary boom 23 originally above the carriage 4 rotates to the side of the carriage 4. The secondary boom 24 is pushed outwards by the hydraulic mechanism in the primary boom 23. Then, the pulley block on the boom is controlled to rotate, driving the cable 25 to descend, hanging the material on the hanging ring 26. Then, the material is hoisted in the reverse direction, and at the same time, the turntable 22 is rotated to make the material reach above the carriage 4, and the material is lowered into the carriage 4. Then, the hanging ring 26 is untied, the hoisting mechanism 5 is reset and shut down. Subsequently, the balance mechanism 6 is retracted, and the user continues to drive the transporter to travel. The steering motor 34 is activated to control the movable shaft 15 and the shovel 16 to rotate downwards until the bottom surface of the shovel 16 closely adheres to the ground surface. During the traveling process, the shovel 16 shovels up and clears the residual coal cinder on the ground. The coal cinder at the edge of the roadway is cleared by activating the linear motor 18 to drive the shovel 16 to horizontally move left and right, closely adhering to the corner position of the roadway, facilitating the clearing of the coal cinder at the edge. When reaching the designated unloading location, the second diagonal pulling oil cylinder 32 is activated to push the support 9 to rotate downwards along the first shaft column 10 until the backing plate 12 supports on the ground, playing a role in supporting and stabilizing the tail of the transporter. Then, through the hydraulic unit in the opening and closing mechanism 27, the claw 28 is horizontally pushed to move away from the door panel 29, releasing the locking of the door panel 29. The first diagonal pulling oil cylinder 30 is activated to push the carriage 4 upwards. The carriage 4 rotates and tilts upwards with the central axis seat 31 as the axis, and the material pours outwards from the door panel 29.
