Description

Technical Field

[0001] The present invention relates to the field of mine auxiliary transportation, and particularly to an articulated chute mechanism. Background Art

[0002] With the successive concepts of replacing humans with mechanization and unmanned with intelligence in the coal industry, the intelligent construction of the mining industry has developed rapidly. At the same time, the requirements for the use of intelligent equipment are getting higher and higher. In the field of mining auxiliary transportation, due to the special working environment underground, in addition to the explosion-proof requirements of the equipment, the equipment is also required to have strong cross-country ability and good mobility. At the same time, higher requirements are put forward for the body size, reliability, and stability.

[0003] Mining auxiliary transportation vehicles are divided into two categories in terms of their operation modes: traction type and self-propelled type. Among them, mine wheeled explosion-proof robots belong to the self-propelled auxiliary transportation category, and are mainly used for the daily auxiliary transportation operations in the explosion-prone dangerous environments of coal mines. They have the functions of transporting equipment, bulk materials, and medium and small-sized materials, and meet relevant industry standards such as waterproof, dustproof, and explosion-proof. The robot integrates key technologies such as advanced wireless communication, sensors, new energy, and hydraulic drive, and can replace manual labor to complete handling and transportation operations in dangerous environments, greatly improving operation safety, work efficiency, and reducing labor intensity, which is of great significance for improving the intrinsic safety operation of coal mines.

[0004] However, existing mine wheeled explosion-proof robots are mostly used in areas with relatively shallow occurrences, and have problems such as poor obstacle-crossing ability, weak mobility, poor reliability, and poor stability.

[0005] Therefore, an articulated chute mechanism is proposed to solve the above problems. Summary of the Invention

[0015] Furthermore, positioning holes are formed on both sides of the connecting rod member at the horizontal part, and positioning pins embedded in the positioning holes are arranged on the connecting plate.

[0016] Furthermore, covers for sealing the first rotating shaft are respectively arranged at both ends of the first rotating shaft on the two side plates, edges of the covers extend outwards to form pressing edges, and pressing rings for fixing the covers on the side plates are arranged on the pressing edges.

[0017] Furthermore, a lubricating and oil replenishing assembly is further included, and the lubricating and oil replenishing assembly includes a ring body arranged on the connecting member and sleeved outside the second rotating shaft, an oil groove arranged inside the ring body, an oil inlet hole and an oil outlet hole communicated with the oil groove arranged on the ring body, an oil outlet pipe for replenishing oil to the first rotating shaft or the second rotating shaft arranged on the oil outlet hole, and a power member arranged on the second rotating shaft for pressing the lubricating oil in the oil groove into the oil outlet pipe.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1:

[0042] Please refer to Figures 1-9 , an articulated chute type mechanism of the present invention is arranged between two axles 7 on the vehicle body, and includes:

[0043] A frame seat 1, fixedly connected to the bottom of the vehicle body and fixed to the bottom of the vehicle body through a support rod, including two side plates 11 arranged front and back and end plates 12 arranged on the upper and lower sides of the two side plates 11;

[0044] Two connecting rod members 2 are respectively arranged on both sides of the frame seat 1, one end is hinged to the axle 7 and the other end is located inside the frame seat 1. A hinge ball joint 24 for ball-hinging the axle 7 is arranged at one end of the connecting rod member 2;

[0045] Two connecting members 3 are arranged inside the frame seat 1 and are located above and below the connecting rod members 2. Both ends of the connecting member 3 are respectively fixedly connected to the connecting rod members 2 on both sides;

[0046] A rotating member 4 is arranged inside the frame seat 1 and is used to connect the connecting member 3, and is used to provide rotation for the connecting member 3 in the vertical and horizontal directions.

[0047] The vehicle body moves with four-wheel drive. Each wheel 8 is individually driven by a drive motor. By controlling and changing the speed difference of the drive motors, by arranging a frame seat 1 fixedly connected to the vehicle body, and arranging the cooperation of the connecting rod member 2, the connecting member 3 and the rotating member 4 hinged to the axle 7, the vehicle body and the axles 7 on both sides are connected through a plurality of hinge structures. The rotating member 4 provides rotation for the connecting member 3 in the vertical and horizontal directions, enabling the axle 7 to rotate in the horizontal and vertical directions relative to the frame seat 1 and the vehicle body, realizing multiple adjustments of the real-time movement state of the vehicle body, greatly improving the off-road ability of the vehicle body to cross obstacles vertically, and fully meeting the application requirements for adapting to various complex terrain working conditions.

[0048] Preferably, the rotating member 4 includes a first rotating shaft 41 rotatably arranged on the side plate 11 and a second rotating shaft 42 vertically rotatably arranged on the first rotating shaft 41. Both ends of the second rotating shaft 42 are respectively rotatably arranged on the two connecting members 3. With this design, both ends of the second rotating shaft 42 are rotatably arranged on the two connecting members 3, and the second rotating shaft 42 is rotatably arranged on the first rotating shaft 41, while the first rotating shaft 41 is rotatably arranged on the side plate 11. Thus, the connecting member 3 and the connecting rod member 2 can rotate in the vertical and horizontal directions relative to the frame seat 1, that is, the axles 7 at both ends of the connecting rod member 2 can move in the vertical and horizontal directions relative to the vehicle body fixedly connected to the frame seat 1, increasing the adaptability of the vehicle body, changing the rigid connection between the traditional frame and the axle 7 into a movable connection, being able to eliminate most of the internal stress changes of the whole machine caused by ground changes, ensuring the overall stability during the movement of the whole machine, and improving the obstacle-crossing ability of the whole machine.

[0049] Preferably, horizontal grooves 411 for placing the connecting member 3 are respectively formed on the upper and lower sides of the first rotating shaft 41. With this design, by arranging the horizontal grooves 411 for placing the connecting member 3 and setting the connecting member 3 as a plate body, the connecting member 3 can be attached to the first rotating shaft 41, and the connecting member 3 can move in the vertical direction with the first rotating shaft 41 as the axis.

[0050] Preferably, a limiting block 412 for limiting the rotation angle of the connecting member 3 is provided on the inner wall of the horizontal groove 411. With this design, the design of the horizontal groove 411 enables the connecting member 3 to rotate horizontally relative to the second rotating shaft 42. By providing the limiting block 412, the connecting member 3 is limited by the limiting block 412 during rotation, thus avoiding the problem of severe oscillation of the vehicle body caused by excessive rotation angle of the connecting rod member 2.

[0051] Preferably, in order to offset the change in internal stress between the axle 7 and the vehicle body caused by terrain changes to the greatest extent, an oval through hole 413 through which the second rotating shaft 42 passes is provided on the first rotating shaft 41, so that the second rotating shaft 42 can slide a small distance on the first rotating shaft 41, which can further ensure the overall stability during the movement of the vehicle body.

[0052] Preferably, horizontal portions 21 are symmetrically provided at the upper and lower ends of the end of the connecting rod member 2 located within the frame seat 1. The connecting member 3 includes a connecting plate 31 that fits against the horizontal portion 21 and a positioning bolt 32 for fixing the connecting plate 31 to the horizontal portion 21. The end face of the connecting plate 31 abuts against the vertical side wall of the horizontal portion 21. With this design, by providing the horizontal portion 21 and setting the connecting member 3 as the connecting plate 31, the contact area between the connecting rod member 2 and the connecting member 3 is increased, facilitating the fixing of the connecting member 3 to the connecting rod member 2. It not only has strong connection but also facilitates subsequent disassembly and repair operations; and the end face of the connecting plate 31 abuts against the vertical side wall of the horizontal portion 21, which can effectively prevent relative deflection between the connecting member 3 and the connecting rod member 2.

[0053] Preferably, positioning holes 22 are provided on both sides of the horizontal portion 21 of the connecting rod member 2, and positioning pins 33 that are inserted into the positioning holes 22 are provided on the connecting plate 31. With this design, by providing the positioning holes 22 on both sides of the horizontal portion 21 and providing the positioning pins 33 that cooperate with the positioning holes 22 on the connecting plate 31, when the connecting member 3 and the connecting rod member 2 are installed, the two connecting rod members 2 and the connecting plate 31 can be pre-constrained together through the cooperation of the positioning pins 33 and the positioning holes 22, and then the latter connecting plate 31 is installed, facilitating the installation between the connecting plate 31 and the connecting rod member 2.

[0054] Preferably, a card slot 23 is provided on the inner side wall of the positioning hole 22, and a protrusion 34 that is adapted to the card slot 23 is provided on the positioning pin 33. With this design, through the cooperation of the card slot 23 and the protrusion 34, the cooperation between the positioning pin 33 and the positioning hole 22 can be further strengthened, thus ensuring the connection strength of the preliminary constraint during installation and making assembly more convenient.

[0055] Preferably, the end of the positioning pin 33 is semi-cylindrical. The ends of the upper and lower positioning pins 33 are fitted together to form a complete cylinder and are adapted to the positioning hole 22. With this design, the two positioning pins 33 enclose a complete cylinder. Combining with the cooperation between the protrusion 34 and the card slot 23, the connection strength between the positioning pin 33 and the positioning hole 22 can be improved. Even when assembling the link member 2 and the connecting member 3, if the link member 2 or the connecting member 3 accidentally slips out of the hand, the link member 2 can still be attached to the connecting member 3.

[0056] The distance between the front and rear articulated chute-type mechanisms is not less than 50% of the distance between the rotating axes of the front and rear wheels 8 on the axle 7. The greater the distance between the front and rear articulated chute-type mechanisms, the more stable the frame supported by the articulated chute-type mechanism, that is, it can resist the large lateral centrifugal force borne by the frame due to high-speed rotation.

[0057] The connection point of the articulated chute-type mechanism and the axle 7 is not lower than the height of the rotating axis of the wheel 8 on the axle 7. Without increasing the width of the vehicle body, the positions of the articulated chute-type mechanism and the rotating axis of the wheel 8 need to be staggered. Lifting the chassis of the wheel 8 will increase the overall passability and make it easier to avoid protrusions on complex ground.

[0058] Embodiment 2:

[0059] As Figure 4 and Figure 10 shown, considering that the operating environment of the vehicle body is relatively complex and there is dust that may contaminate the connection between the first rotating shaft 41 and the side plate 11, affecting the normal rotation of the first rotating shaft 41, on both sides of the side plate 11, covers 43 for sealing the first rotating shaft 41 are respectively provided at both ends of the first rotating shaft 41. The edge of the cover 43 extends outward to form a pressing edge 44. A pressing ring 45 for fixing the cover 43 on the side plate 11 is provided on the pressing edge 44. Mounting holes 46 for fixing on the side plate 11 are evenly provided on the pressing ring 45. With this design, by providing the cover 43, the end of the first rotating shaft 41 can be covered to prevent external dust from entering the connection between the first rotating shaft 41 and the side plate 11 and affecting the rotation of the first rotating shaft 41. By providing the pressing ring 45, the pressing edge 44 at the edge of the cover 43 can be tightened, and by providing the mounting holes 46, the cover 43 can be fixed and pressed on the side plate 11, thus ensuring the sealing performance.

[0060] Embodiment 3:

[0061] As Figure 6 and Figure 11As shown, considering the operating environment of the vehicle body, the ground is relatively complex, uneven, with ore obstacles, etc., which makes the relative movement stroke of the movable parts on the vehicle body relatively large during the movement of the vehicle body. Especially for the articulated chute mechanism, the internal structure has a relatively large amount of frictional movement. In order to reduce wear and extend its service life, it further includes a lubricating oil replenishing component 5. The lubricating oil replenishing component 5 includes a ring body 51 provided on the connecting member 3 and sleeved outside the second rotating shaft 42, and an oil groove 52 provided in the ring body 51. An oil inlet hole and an oil outlet hole communicating with the oil groove 52 are provided on the ring body 51. An oil outlet pipe 53 for replenishing oil to the first rotating shaft 41 or the second rotating shaft 42 is provided on the oil outlet hole. A power member 55 for pressing the lubricating oil in the oil groove 52 into the oil outlet pipe 53 is provided on the second rotating shaft 42. An oil inlet pipe 54 for feeding oil into the oil groove 52 is provided on the oil inlet hole. One-way valves are respectively provided on the oil inlet pipe 54 and the oil outlet pipe 53. With such a design, by providing the oil groove 52 for storing lubricating oil and the supporting oil inlet pipe 54 and oil outlet pipe 53, the power member 55 can press the lubricating oil into the rotating parts between the first rotating shaft 41 and the side plate 11 and between the second rotating shaft 42 and the first rotating shaft 41, so as to realize the lubrication of the rotating parts between the first rotating shaft 41 and the side plate 11 and between the second rotating shaft 42 and the first rotating shaft 41, avoid the situation of large wear caused by a relatively large amount of frictional movement of the internal structure due to insufficient lubrication during long-term use, and extend the service life. In addition, by respectively providing one-way valves on the oil inlet pipe 54 and the oil outlet pipe 53, the conveying path of the lubricating oil is restricted, ensuring that the lubricating oil can effectively lubricate the rotating parts between the first rotating shaft 41 and the side plate 11 and between the second rotating shaft 42 and the first rotating shaft 41.

[0062] Preferably, the power component 55 includes notches 551 symmetrically distributed on both sides of the ring body 51, push blocks 552 slidably arranged in the notches 551, and piston rods 553 arranged in the oil grooves 52 on both sides of the notches 551. One end of the piston rod 553 passes through the notch 551 and is fixed on the push block 552. A clamping block 421 for driving the push block 552 to rotate is arranged on the second rotating shaft 42. The push block 552 is arranged in a U-shaped structure, and the clamping block 421 is clamped in the U-shaped structure of the push block 552. The two oil outlet pipes 53 on one side of the two notches 551 are respectively used for lubricating the same place. With such a design, by setting the cooperation between the push block 552 and the clamping block 421, during the rotation of the second rotating shaft 42, the push block 552 can be driven to move, thereby pressing one side of the piston rod 553. During the pressing process of the piston rod 553, the lubricating oil in the oil groove 52 is pressed into the oil outlet pipe 53, and under the action of the two oil outlet pipes 53 on both sides, lubrication is achieved at the rotation points of the first rotating shaft 41 and the side plate 11, and the second rotating shaft 42 and the first rotating shaft 41. By using the two oil outlet pipes 53 on one side of the two notches 551 to lubricate the same place respectively, when the second rotating shaft 42 rotates, the two oil outlet pipes 53 that press out the lubricating oil are respectively located on both sides of the two notches 551, so as to simultaneously lubricate the rotation points of the first rotating shaft 41 and the side plate 11, and the second rotating shaft 42 and the first rotating shaft 41, avoiding lubricating only one place.

[0063] Embodiment 4:

[0064] As Figures 12-14 shown, in order to reduce the possibility of external dust penetrating into the frame seat 1 and play a role in overall dust protection for the articulated chute mechanism, sealing covers 6 for sealing the frame seat 1 are symmetrically arranged outside the frame seat 1. One end of the sealing cover 6 is included on the link member 2, and the other ends of the two sealing covers 6 are fixedly connected. With such a design, by symmetrically arranging the two sealing covers 6 and fixedly connecting the two sealing covers 6, the frame seat 1 can be sealed, preventing external dust from entering the frame seat 1, providing dust protection for the frame seat 1, and improving the service life of the frame seat 1.

[0065] Preferably, considering that the setting of the sealing cover 6 will hinder the connection between the frame seat 1 and the vehicle body frame, a support rod is arranged on the frame seat 1. The lower end of the support rod passes through the sealing cover 6 and is fixed on the frame seat 1, while the upper end of the support rod is fixedly connected to the vehicle body. With such a design, the structural stability of the frame seat 1 can be ensured, and the protection of the frame seat 1 can be realized.

[0066] Preferably, the sealing cover 6 is made of rubber. With this design, firstly, the rubber sealing cover 6 can be attached together to ensure the sealing of the frame seat 1. Secondly, it can provide a certain degree of impact protection for the frame seat 1 to avoid damage to the frame seat 1 caused by obstacles.

[0067] Preferably, an annular groove 25 is formed in the connecting rod member 2, and one end of the sealing cover 6 is clamped in the annular groove 25. With this design, by providing the annular groove 25, firstly, the sealing performance between the sealing cover 6 and the connecting rod member 2 is improved. Secondly, the annular groove 25 can restrain the sealing cover 6 to prevent the sealing cover 6 from moving on the connecting rod member 2 and ensure the normal use of the sealing cover 6.

[0068] Preferably, support plates 61 made of rubber are respectively arranged in the two sealing covers 6, and the bottom ends of the support plates 61 abut against the end plates 12. With this design, by providing the support plates 61, after the sealing cover 6 is hit by foreign objects on the ground, the sealing cover 6 can quickly recover. Even after the sealing cover 6 is hit by foreign objects on the ground, the sealing cover 6 can still wrap the frame seat 1 in the initial expanded state, avoiding wear of the frame seat 1 caused by the deformation of the sealing cover 6 that cannot be restored after being hit.

[0069] Preferably, an annular clamping plate 62 is arranged on the sealing cover 6, and the clamping plates 62 on the two sealing covers 6 are fixed by bolts. With this design, by providing the clamping plate 62, it is convenient to connect the two sealing covers 6. Secondly, the clamping plate 62 can clamp the edges of the sealing cover 6, making the external edges of the sealing cover 6 receive uniform force and having stronger sealing performance.

[0070] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
