Description

Technical Field

[0001] The present invention belongs to the technical field of mine transportation equipment, and specifically relates to a mine trackless vehicle and its control method. Background Art

[0002] With the rapid development of mining technologies such as coal mines and metal mines, the production capacity of mines has been greatly improved, and their scale has become larger and larger. Mine transportation is an indispensable and important part of the mine production process. In mine transportation, the mine trackless vehicle is an important transportation equipment, which is widely used in underground material transportation, personnel transportation and other operations. With the continuous expansion of the mine exploitation scale and the gradual increase of the exploitation depth, higher requirements are put forward for the performance and safety of the mine trackless vehicle.

[0003] Currently, in terms of braking, the braking method of traditional mine trackless vehicles usually achieves deceleration braking by keeping the brake pads in contact with the rails for friction all the time. During this braking process, due to continuous friction, a large amount of heat will be generated. Excessively high temperature is extremely likely to cause the brake pads to deform or severely wear. On the one hand, the service life of the brake pads will be greatly shortened. Frequent replacement of the brake pads not only increases the maintenance cost, but also affects the normal transportation operation progress of the mine, resulting in double losses in terms of time and economy. On the other hand, after the brake pads are worn or deformed due to high temperature, the braking effect will be greatly reduced, and a stable and reliable braking force cannot be provided, seriously affecting the safety of mine trackless vehicle transportation, and even possibly triggering transportation accidents, threatening the lives of underground workers and the normal progress of mine production.

[0004] In view of this, a novel mine trackless vehicle is specifically proposed, which can effectively reduce the heat generation during braking, reduce the wear of the brake pads, improve the braking effect and transportation safety, so as to meet the actual needs of efficient and safe mine transportation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a mine trackless vehicle and its control method that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a mine trackless vehicle, including a bottom frame, on both sides of the bottom frame are symmetrically and fixedly connected with brackets, between the two brackets is arranged a carriage, at the bottom of the bottom frame are symmetrically and rotatably connected with rotating shafts through supports, at both ends of the rotating shafts are fixedly connected with track wheels through nuts, and further includes: lifting plates symmetrically arranged on both sides of the bottom frame, on both sides of the bottom frame are symmetrically provided with through openings, and the lifting plates are slidably connected in the adjacent through openings; braking blocks for use in cooperation with railway tracks, which are detachably installed at the lower ends of the lifting plates through fixing bolts; a driving mechanism for driving the two lifting plates to move up and down quickly synchronously, which is installed at the lower end of the bottom frame.

[0007] Further, the driving mechanism includes a double-shaft motor, an eccentric disk, a fixing plate and a T-shaped block. The double-shaft motor is installed at the middle position of the bottom of the bottom frame through a support plate, the eccentric disk is fixedly connected to the two output ends of the double-shaft motor, the fixing plate is fixedly connected to the side of the lifting plate close to the double-shaft motor, the T-shaped block is fixedly connected to the fixing plate, a T-shaped sliding groove is formed in a circle on the eccentric disk, and the T-shaped block is slidably connected in the T-shaped sliding groove.

[0008] In order to facilitate the eccentric disk to drive the lifting plate to move up and down more stably, furthermore, the fixing plates are symmetrically arranged on the upper and lower sides of the eccentric disk.

[0009] In order to facilitate the opening of the carriage to always be in an upward state, furthermore, the carriage and the bracket are rotatably connected through a rotating shaft.

[0010] In order to facilitate reducing the center of gravity of the trackless vehicle, still further, a counterweight box is fixedly connected to the bottom frame, and the double-shaft motor is fixedly connected to the bottom of the counterweight box through a support plate.

[0011] In order to further improve the heat dissipation and cooling effect of the braking block, still further, the counterweight box is a water tank, on both sides of the bottom of the bottom frame located at the counterweight box are symmetrically and fixedly connected with suction cylinders, in the suction cylinders are slidably connected with piston rods with pistons, one end of the piston rod extending downward out of the suction cylinder is fixedly connected to the fixing plate, one-way valves are arranged in the water inlet and outlet of the suction cylinder, a diversion cavity is formed inside the lifting plate, a plurality of water delivery channels communicating with the diversion cavity are equidistantly and downwardly inclined on the lifting plate, the water outlet of the water delivery channel is arranged on the side of the lifting plate close to the railway track, the water inlet of the suction cylinder is connected with a suction pipe, the water outlet of the suction cylinder is connected with a water delivery pipe, the suction end of the suction pipe extends into the interior of the counterweight box, and the water outlet end of the water delivery pipe is connected with the water inlet end of the diversion cavity.

[0012] In order to facilitate guiding the suction pipe of the water tank, furthermore, a diversion plate is fixedly connected to the lower end inside the counterweight box.

[0013] In order to facilitate increasing the contact area between the brake block and air and cooling water and further improve the heat dissipation effect on the brake block, further, a plurality of ventilation holes are equidistantly formed in the brake block.

[0014] In order to facilitate improving the support stability of the carriage, further, a reinforcing rib bar is fixedly connected between the bracket and the bottom frame.

[0015] A control method for a mine trackless vehicle mainly includes the following steps:

[0016] S1: When preparing to start the mine trackless vehicle, first check the states of all components of the vehicle to ensure that all components are firmly connected without looseness or damage. Confirm that the lifting plate slides smoothly through the opening of the bottom frame, and the brake block is firmly installed and separated from the railway track.

[0017] S2: After checking and confirming, start the power system of the trackless vehicle (not the key part of this design). The track wheels roll on the railway track, and the trackless vehicle travels normally. At this time, the brake block does not contact the railway track to avoid unnecessary frictional losses.

[0018] S3: When it is necessary to load and unload goods, the double-shaft motor can be driven to drive the eccentric disc to rotate at this time, so that the lifting plate moves up to the highest position. Further, the brake block can be kept in close contact with the railway track, thereby realizing the stop of the mine trackless vehicle.

[0019] S4: When braking is required during the driving of the trackless vehicle, the operator can control the double-shaft motor to be powered on and started through the start button. The output ends on both sides drive the eccentric disc to rotate rapidly, driving the lifting plate to move up and down rapidly. Further, the brake block contacts and rubs against the railway track rapidly and intermittently to realize spot braking.

[0020] S5: The operator can flexibly adjust the braking intensity and effect according to the actual braking requirements by controlling the start duration and rotation speed of the double-shaft motor (if the motor has a speed regulation function). For example, briefly pressing the start button lightly, the double-shaft motor drives the brake block to perform spot braking actions less frequently to achieve slight deceleration. Pressing and holding for a long time or appropriately increasing the motor rotation speed can achieve a stronger braking effect, causing the trackless vehicle to stop quickly.

[0021] S6: After braking is completed, turn off the control switch of the double-shaft motor. The brake block stops moving up and down and remains separated from the railway track (if there is an automatic reset structure, it will be automatically reset. If not, it is necessary to manually check and confirm that the brake block returns to the initial separated position).

[0022] S7: Then check the states of all components of the trackless vehicle again. After ensuring that there is no abnormality, if it is necessary to continue driving, operate according to the normal driving start process. If it is not necessary to continue working, the brake block can be kept in close contact with the railway track to prevent the trackless vehicle from slipping.

[0023] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By adopting the method of spot braking, the present invention can make the brake block contact the rail intermittently. Compared with continuous friction, the heat generated during braking is greatly reduced. Due to the reduction of heat, the deformation and severe wear of the brake block caused by high temperature are improved, effectively prolonging the service life of the brake block, reducing the maintenance cost and time of frequently replacing the brake block, and also avoiding the problem that the braking performance is reduced due to high temperature wear or deformation of the brake block, making the braking effect more stable and reliable, thereby improving the safety during the transportation of the mine trackless vehicle and ensuring the smooth progress of the transportation operation.

Specific Embodiments

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0035] Embodiment 1:

[0036] Referring to Figures 1-7 , a mine track-mounted vehicle includes a bottom frame 1. On both sides of the bottom frame 1, brackets 101 are symmetrically and fixedly connected. Between the two brackets 101, a carriage 102 is arranged. At the bottom of the bottom frame 1, a rotating shaft 104 is symmetrically and rotatably connected through a support. At both ends of the rotating shaft 104, track wheels 105 are fixedly connected through nuts. It further includes: lifting plates 201 symmetrically arranged on both sides of the bottom frame 1. Through openings are symmetrically formed on both sides of the bottom frame 1, and the lifting plates 201 are slidably connected in the adjacent through openings; brake blocks 202 used in cooperation with the railway tracks, which are detachably installed at the lower ends of the lifting plates 201 through fixing bolts; a driving mechanism for driving the two lifting plates 201 to move up and down quickly synchronously, which is installed at the lower end of the bottom frame 1.

[0037] The driving mechanism includes a double-shaft motor 3, an eccentric disk 301, a fixing plate 303, and a T-shaped block 304. The double-shaft motor 3 is installed at the middle position of the bottom of the bottom frame 1 through a support plate. The eccentric disk 301 is fixedly connected to the two output ends of the double-shaft motor 3. The fixing plate 303 is fixedly connected to the side of the lifting plate 201 close to the double-shaft motor 3. The T-shaped block 304 is fixedly connected to the fixing plate 303. A T-shaped sliding groove 302 is formed in a circle on the eccentric disk 301, and the T-shaped block 304 is slidably connected in the T-shaped sliding groove 302.

[0038] This mine track-mounted vehicle is mainly composed of a bottom frame 1, brackets 101, a carriage 102, a rotating shaft 104, track wheels 105, lifting plates 201, brake blocks 202, and a driving mechanism. The carriage 102 is arranged between the two brackets 101 and is used to carry goods. The track wheels 105 rotate at the bottom of the bottom frame 1 through the rotating shaft 104 and are firmly connected by nuts, enabling the track-mounted vehicle to run smoothly on the track.

[0039] In addition, the lifting plates 201 are symmetrically arranged on both sides of the bottom frame 1. Through openings are formed at corresponding positions of the bottom frame 1, and the lifting plates 201 can slide flexibly in the through openings. The brake blocks 202 are detachably installed at the lower ends of the lifting plates 201 through fixing bolts. The brake blocks 202 cooperate with the railway tracks to achieve the braking function, and the driving mechanism is installed at the lower end of the bottom frame 1 and is the key component for realizing the braking operation.

[0040] During the normal running of the rail-mounted vehicle, the brake block 202 remains separated from the rail to ensure smooth running. When braking is required, the double-shaft motor 3 is started, and the output ends on both sides drive the eccentric disk 301 to rotate rapidly. Since the T-shaped chute 302 is provided on the eccentric disk 301, and the T-shaped block 304 is fixed on the fixing plate 303 connected to the lifting plate 201 and slidably connected in the T-shaped chute, therefore, with the cooperation of the through-port of the bottom frame 1, the fixing plate 303 and the T-shaped block 304, the eccentric disk 301 can drive the lifting plate 201 to move up and down rapidly, and then the brake block 202 can be in rapid and intermittent contact friction with the rail, realizing point braking.

[0041] During the process of loading and unloading goods, when it is necessary to stop the mine rail-mounted vehicle, at this time, the double-shaft motor 3 can be driven to drive the eccentric disk 301 to rotate, so that the lifting plate 201 moves up to the highest position, and then the brake block 202 can be kept in close contact with the rail all the time, thereby realizing the stop of the mine rail-mounted vehicle.

[0042] When the traditional mine rail-mounted vehicle brakes, the brake block 202 is always in contact friction with the rail, which will generate a large amount of heat. While this mine rail-mounted vehicle adopts the point braking method, the brake block 202 is in intermittent contact with the rail. Compared with continuous friction, the heat generated during braking is greatly reduced. Due to the reduction of heat, the deformation and severe wear of the brake block 202 caused by high temperature are improved, effectively prolonging the service life of the brake block 202, reducing the maintenance cost and time of frequently replacing the brake block 202, and also avoiding the problem that the braking performance is reduced due to high-temperature wear or deformation of the brake block 202, making the braking effect more stable and reliable, thereby improving the safety during the transportation of the mine rail-mounted vehicle and ensuring the smooth progress of the transportation operation.

[0043] Embodiment 2:

[0044] Refer to Figures 1-7 , a mine rail-mounted vehicle, which is basically the same as Embodiment 1. Further, the fixing plates 303 are symmetrically arranged on the upper and lower sides of the eccentric disk 301. By arranging the fixing plates 303 and the T-shaped blocks 304 on both the upper and lower sides of the eccentric disk 301, the eccentric disk 301 can drive the lifting plate 201 to move up and down more stably, effectively improving the stability of the lifting plate 201 during movement.

[0045] The carriage 102 is rotatably connected to the bracket 101 through a rotating shaft. By making the carriage 102 rotatably connected to the bracket 101, when affected by the terrain, the two rails are not on the same horizontal plane and the bottom frame 1 is inclined, due to the rotating connection between the carriage 102 and the bracket 101, the carriage 102 can always be in a vertically upward state, avoiding the problem that the goods in the carriage 102 fall due to the inclination of the vehicle body.

[0046] A counterweight box 2 is fixedly connected to the bottom frame 1. The double-shaft motor 3 is fixedly connected to the bottom of the counterweight box 2 through a support plate. By setting the counterweight box 2, the overall center of gravity of the mine rail-mounted vehicle can be lowered to a lower position. Thus, when the mine rail-mounted vehicle tilts, the overall stability can be ensured.

[0047] Embodiment 3:

[0048] Refer to Figures 1-7 , a mine rail-mounted vehicle, which is basically the same as Embodiment 2. Further, the counterweight box 2 is a water tank. On both sides of the bottom of the bottom frame 1 symmetrically and fixedly connected to the counterweight box 2 are suction cylinders 4. A piston rod 401 with a piston is slidably connected in the suction cylinder 4. One end of the piston rod 401 extending downward from the suction cylinder 4 is fixedly connected to a fixing plate 303. Check valves are provided in the water inlet and outlet of the suction cylinder 4. A diversion chamber 203 is opened inside the lifting plate 201. A plurality of water delivery channels 204 communicating with the diversion chamber 203 are equidistantly and downwardly inclined on the lifting plate 201. The water outlet of the water delivery channel 204 is arranged on the side of the lifting plate 201 close to the railway track. The water inlet of the suction cylinder 4 is connected to a suction pipe 402, and the water outlet of the suction cylinder 4 is connected to a water delivery pipe 403. The suction end of the suction pipe 402 extends into the interior of the counterweight box 2, and the water outlet end of the water delivery pipe 403 is connected to the water inlet end of the diversion chamber 203.

[0049] During the braking process, a large amount of heat will be generated due to the friction between the brake block 202 and the railway track, which is likely to cause a decline in its performance and a shortening of its service life. By setting structures such as the suction cylinder 4, the piston rod 401, the diversion chamber 203, and the water delivery channels 204, when the double-shaft motor 3 drives the eccentric disk 301 to rotate and the lifting plate 201 moves up and down, the piston rod 401 will be synchronously driven to reciprocate in the suction cylinder 4. Under the action of the check valves at the water inlet and outlet of the suction cylinder 4, water is extracted from the counterweight box 2, sent into the diversion chamber 203 through the water delivery pipe 403, and then sprayed onto the brake block 202 through the water delivery channels 204 in a timely manner to take away the heat, avoiding problems such as deformation and increased wear of the brake block 202 due to high temperature, further ensuring that the brake block 202 is always in a good working state and extending its service life.

[0050] The water delivery channels 204 are equidistantly and downwardly inclined and communicate with the diversion chamber 203. Such a design enables the water flow to flow out of the water delivery channels 204 evenly and appropriately under the action of pressure, ensuring both sufficient water for cooling the brake block 202 and avoiding problems such as waste of water resources caused by excessive water delivery or interference with the braking effect due to excessive water flow. With the water delivery volume within a reasonable range, efficient cooling of the brake block 202 can be achieved while maintaining the stable operation of the entire system.

[0051] Embodiment 4:

[0052] Refer to Figures 1-7, a mine rail-bound vehicle, which is basically the same as Embodiment 3. Further, a drainage plate 2001 is fixedly connected to the lower end inside the counterweight box 2.

[0053] The drainage plate 2001 is fixed to the lower end inside the counterweight box 2, which can guide the water in the box to converge towards the suction end of the suction pipe 402. When the suction cylinder 4 works to extract the water in the counterweight box 2, the drainage plate 2001 can make the water flow more smoothly towards the suction pipe 402, reduce the suction difficulty caused by uneven distribution of water in the box, improve the pumping efficiency, ensure the stable supply of cooling water to the brake block 202, and guarantee the reliable operation of the cooling system.

[0054] During the use process, the water in the counterweight box 2 will be continuously extracted. The inclination angle and shape design of the drainage plate 2001 can prompt the water in the box to flow towards a specific area under the action of gravity, so that most of the water can be effectively extracted, reduce the residual water accumulation, prevent the water accumulation from breeding impurities, microorganisms, etc. that affect the water quality, and further affect the cooling effect and the normal operation of the system.

[0055] Embodiment 5:

[0056] Refer to Figures 1-7 , a mine rail-bound vehicle, which is basically the same as Embodiment 4. Further, a plurality of ventilation holes 2010 are equidistantly arranged on the brake block 202. When the brake block 202 works, a large amount of heat is generated due to friction with the rail. The existence of the ventilation holes 2010 increases the contact area between the brake block 202 and the air and cooling water. The air and cooling water can flow inside the brake block 202 through the ventilation holes 2010, accelerate the heat dissipation, take away the heat generated by friction, effectively reduce the temperature of the brake block 202, avoid problems such as performance degradation and increased wear caused by overheating, and extend the service life of the brake block 202.

[0057] And when the brake block 202 is briefly separated from the rail, the air can quickly enter and flow out of the brake block 202 through the ventilation holes 2010, enhancing the air-cooling effect. Combining with the point-brake braking mode of this rail-bound vehicle, the ventilation holes 2010 can better assist in heat dissipation during the braking interval, cooperate with the spray cooling, further improve the heat dissipation efficiency, enable the brake block 202 to quickly return to the appropriate working temperature, and guarantee the stable and reliable operation of the braking system.

[0058] There is a reinforcing rib rod 103 fixedly connected between the support 101 and the bottom frame 1. During the operation of the mine rail-bound vehicle, the carriage 102 will carry heavy loads, which will bring greater pressure to the support 101 and then transfer to the bottom frame 1. The reinforcing rib rod 103 connects the support 101 and the bottom frame 1, which can effectively disperse stress, just like adding a stable support structure between the support 101 and the bottom frame 1. It enables the support 101 to still maintain a firm connection with the bottom frame 1 when bearing the gravity from the carriage 102 and external forces such as bumps and vibrations during driving, preventing the support 101 from deforming or detaching from the bottom frame 1 due to uneven stress, and greatly improving the structural stability of the entire mine rail-bound vehicle.

[0059] Through the strengthening effect of the reinforcing rib rod 103, the overall structure of the mine rail-bound vehicle is more robust and durable, and can bear greater weights. This means that in actual mine transportation operations, heavier goods can be transported, improving transportation efficiency and productivity, meeting the transportation requirements of the mine for goods of different weights, and at the same time reducing the risk of potential safety hazards due to insufficient structural strength.

[0060] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.

If not, the operator needs to check manually to confirm that the brake block (202) returns to the initial separated position); S7: Then check the status of each component of the rail-bound vehicle again. After ensuring that there is no abnormality, if it is necessary to continue driving, operate according to the normal driving start process. If there is no need to continue working, the brake block (202) can be kept in close contact with the rail to prevent the rail-bound vehicle from slipping.
