Description

Technical Field

[0001] This invention relates to the field of braking equipment technology for mining locomotives, specifically a dual-type braking system for mining battery locomotives. Background Technology

[0002] Mining battery locomotives are mainly used for underground transportation and long-distance surface transportation. They are equivalent to electric locomotives in railway transportation, pulling trains composed of mine cars or personnel cars on the track to transport coal, gangue, materials, equipment, and personnel. Mining battery locomotives implement emergency braking in case of emergencies or red lights. However, the mining battery locomotives currently used in mines in my country generally have the problem of exceeding the braking distance limit. Therefore, the dual-type braking system of mining battery locomotives is of great significance in the field of mining locomotives today.

[0003] The existing braking system of mining battery locomotives is achieved by the driver manually turning the handwheel, which in turn drives the screw, transmission rod and brake rod to transmit force to the brake shoes, so that the brake shoes press against the front and rear wheels to achieve the braking effect. The transmission of braking torque is achieved through the screw drive. When the screw rotates, the braking time is prolonged, so the braking speed is relatively slow. These mechanical braking methods have a low safety factor.

[0004] Secondly, when the brake disc needs to be replaced after a long period of use, the mechanic uses disassembly tools to remove the disc from under the car. Specifically, he unscrews multiple bolts with one hand and lifts the disc with the other to prevent it from falling. However, this operation is complicated and disassembly is troublesome. When installing the disc, the bolts also need to be installed one by one, which increases the workload of the mechanic. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a dual-type braking system for mining battery locomotives, which can effectively solve the problems of slow braking speed and complicated disassembly of the grinding disc.

[0015] Preferably, the air pump assembly includes a through box installed at the bottom of the connecting plate.

One end of the pump pipe extends into the interior of the through box and is fitted with a branch pipe head. Two piston grooves are formed in the bottom cavity of the through box. The inner sides of the two piston grooves are connected to the branch pipe head via a connecting pipe. A piston plate is slidably connected to the inner side of the piston groove. A piston rod is installed on the opposite side of the two piston plates. One end of the piston rod extends out of the outside of the through box and is fitted with an arc-shaped pressing member. A fixing rod is installed between the drive blocks located on the front and rear sides. The inner side of the arc-shaped pressing member presses against the outer side of the fixing rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention uses air inside the air pump assembly to push the arc-shaped pressing component, which in turn pushes the fixed rod to push the drive block on the control assembly. This, in turn, drives the first and second rotating plates on both sides through the first and second passive blocks, thereby achieving the purpose of braking the brake disc with the grinding disc. Compared with the driver manually turning the handwheel to drive the screw, transmission rod and brake rod to transmit force to the brake shoes and make the brake shoes press against the front and rear wheels, this invention has a more timely braking effect and a faster braking speed.

[0020] 2. This invention allows for quick disassembly of components by simply loosening the main bolt with a wrench. The main bolt loosens the first bolt, and simultaneously, through the interaction of the first and second connecting gears, the second bolt disengages from the first or second rotating plate. This facilitates the rotation of the rotating plate, and the brake disc, freed from the pressure of the rotating plate and the constraint of the first bolt, can be removed. Furthermore, this invention uses three limiting support blocks and locking blocks to automatically press the grinding disc, making it less likely to fall off. It also facilitates quick installation or removal of the grinding disc by maintenance personnel, reducing their workload.

[0021] 3. The present invention, through the cooperation of the moving block, slide rail, lead screw, torsion disc and the first return spring, facilitates the adjustment of the distance between the two grinding discs, making it easy for the two grinding discs to be used with different brake discs. Moreover, when the first return spring is deformed and cannot be restored, it can be disassembled and replaced quickly. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] like Figures 1-3 As shown, the present invention provides a technical solution: a dual-type mining battery-powered locomotive braking system, including a locomotive housing 1, with multiple locomotive underframes 2 mounted on the bottom of the locomotive housing 1. A connecting plate 3 is installed between the front and rear locomotive underframes 2. Each locomotive underframe 2 has a wheel 4 on one side. A drive rod 40 is installed between the front and rear wheels 4. A brake disc 5 is installed on the outer side of the drive rod 40 and on the opposite side of the wheel 4. Grinding discs 51 for controlling the brake disc 5 are provided on the left and right sides of the brake disc 5. A bearing disc (not shown in the figure) is rotatably connected to the outer side of the drive rod 40 via a bearing between the wheel 4 and the brake disc 5. A control component 6 for driving the grinding disc 51 and controlling the brake disc 5 is provided on the bearing disc. Component 6 includes two mounting blocks 61 mounted on the top of the connecting plate 3. Rotating components 62 are rotatably connected to the left and right sides of the two mounting blocks 61. Connecting blocks 63 are mounted on opposite sides of the rotating components 62. A rotating shaft 64 is mounted on the top of the connecting block 63. A first rotating plate 65 and a second rotating plate 66 are rotatably connected to the left and right ends of the outer side of the rotating shaft 64, respectively. A mating block 67 is mounted at the bottom of the first rotating plate 65 and the second rotating plate 66. A first return spring 68 is provided between the mating blocks 67. A driving block 69 is rotatably connected to the bottom of the connecting block 63. A first passive block 610 is rotatably connected to the mating block 67 on the left side. A second passive block 611 is rotatably connected to the bottom of the driving block 69. The driving block 69 and the first passive block 610 are fixedly connected.

[0045] During operation, when the drive block 69 moves upward, it drives the first passive block 610 and the second passive block 611 connected to it to move. The mating blocks 67 on both sides move relative to each other under the pressure of the first passive block 610 and the second passive block 611, causing the grinding disc 51 on the first rotating plate 65 and the second rotating plate 66 to move closer to the outside of the brake disc 5, so as to increase the friction between the grinding disc 51 and the brake disc 5, thereby achieving the braking effect on the brake disc 5. Compared with the driver manually turning the handwheel to drive the screw, transmission rod and brake rod to transmit force to the brake shoes and make the brake shoes press against the front and rear wheels, the braking effect of this invention is more timely and the braking speed is faster.

[0046] Example 2:

[0047] As one embodiment of the present invention, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a quick-release assembly 9 for quickly disassembling the grinding disc 51 is provided between the grinding disc 51 and the control assembly 6. The quick-release assembly 9 includes a rotating plate 91 rotatably connected to the side of the first rotating plate 65 away from the wheel 4. A dustproof box 92 is installed on the side of the rotating plate 91 away from the first rotating plate 65. A main bolt rod 93 for controlling the grinding disc 51 is threadedly connected to the middle of the dustproof box 92. A pressure plate 96 is provided on the side of the rotating plate 91 facing away from the first rotating plate 65. A pressure plate 96 is installed at the upper and lower ends of the rotating plate 91 on the pressure plate 96 for pressing the pressure plate 96. The limiting and fixing rod 99 of the 6th limit is connected to the middle of the pressing plate 96 with a first bolt rod 94 that is fixedly connected to the main bolt rod 93. A first connecting gear 95 is installed on the side of the first bolt rod 94 facing away from the rotating plate 91. The pressing plate 96 is connected to the upper and lower sides of the first bolt rod 94 with a second bolt rod 97. A second connecting gear 98 that meshes with the first connecting gear 95 is installed on the side of the second bolt rod 97 facing away from the pressing plate 96. The inner side of the limiting support block 511 in the middle is provided with a part that connects with the first bolt rod 94. To accommodate the locking threaded hole 940, the first rotating plate 65 has a threaded groove 651 on the side facing away from the wheel 4 that matches the second bolt rod 97. The three limiting support blocks 511 are evenly spaced and form an isosceles triangle. Three limiting support blocks 511 are installed on the side of the brake disc 5 away from the brake disc 5. Two limiting rods 512 are installed at the bottom of the limiting support blocks 511. The first rotating plate 65 has a portion on the side facing away from the wheel 4 that matches the three limiting support blocks 511 and part of the grinding disc 51. A matching triangular groove 650 is provided, and a limiting groove 513 matching the limiting rod 512 is provided in the triangular groove 650. A locking block 652 is slidably connected to the upper and lower side walls in the triangular groove 650. An expansion spring is connected between the first rotating plate 65 and the two opposite locking blocks 652. A locking groove 653 is provided on one side of the locking block 652 corresponding to the limiting support block 511. A baffle 661 is installed at the bottom of the first rotating plate 65 and the second rotating plate 66. A baffle groove 660 matching the baffle 661 is provided at the bottom of the rotating plate 91.

[0048] When replacing the grinding disc 51 during operation, the maintenance personnel only need to use a wrench to turn the two main bolt rods 93. The main bolt rods 93 drive the first bolt rod 94 to loosen, causing the first bolt rod 94 to disengage from the limit support block 511 and the first rotating plate 65, thus enabling quick disassembly and installation of the grinding disc 51. Simultaneously, the rotation of the first bolt rod 94 drives the first connecting gear 95 to rotate, causing the second bolt rods 97 at both ends of the first connecting gear 95 to rotate synchronously, thereby disengaging the rotating plate 91 from the first rotating plate 65 or the second rotating plate 66. Then, the maintenance personnel can rotate the rotating plate 91 to disassemble the grinding disc 51. During the rotation of the first bolt rod 94 and the second bolt rod 97, the pressing plate 96 slides along the upper limit of the limit fixing rod 99, which helps to ensure that the first connecting gear 95 and the second connecting gear 98 remain engaged. When the maintenance personnel disassemble the grinding disc 51, there is no need to lift the grinding disc 51 during the entire process, improving the disassembly and installation efficiency of the grinding disc 51.

[0049] It should be noted that the present invention sets the spacing between the limiting support blocks 511 to be equal, and the three limiting support blocks 511 form an isosceles triangle structure, so as to facilitate the transmission of the force on the brake disc 5 through the brake disc 5, and then through the three limiting support blocks 511 and the limiting rod 512 to the first rotating plate 65 or the second rotating plate 66, thereby increasing the friction between the brake disc 5 and the grinding disc 51, and thus achieving the purpose of rapid braking of the brake disc 5. Moreover, the three limiting support blocks 511 are respectively in the triangular groove 650, which is beneficial to prevent the brake disc 5 from falling off during the disassembly of the grinding disc 51.

[0050] It is worth noting that the present invention locks the limiting support block 511 with the locking block 652 and the expansion spring, which is beneficial to the fact that during the installation process, the maintenance personnel only need to press the limiting support block 511 onto the triangular groove 650 so that the limiting support block 511 can be restrained by the locking block 652, which is beneficial to further prevent the grinding disc 51 from falling off.

[0051] It is worth noting that the present invention provides a baffle 661 and a baffle groove 660 so that when the maintenance personnel drive the rotating plate 91, the baffle groove 660 on the rotating plate 91 is bound to the baffle 661. Then, the first bolt rod 94 and the second bolt rod 97 correspond to the locking threaded hole 940 and the threaded groove 651 respectively, which facilitates the maintenance personnel to lock quickly.

[0052] Example 3:

[0053] As one embodiment of the present invention, such as Figure 3 and Figure 8As shown, a storage box 681 is installed at the bottom of the mating block 67 located at the right end. A storage slot is provided inside the storage box 681. A moving block 682 is fixedly connected to the first return spring 68 inside the storage slot. A slide rail 683 is installed inside the storage slot and is slidably connected to the moving block 682. A lead screw 684 is threadedly connected to the middle of the moving block 682. A torsion plate 685 is installed on the side of the lead screw 684 away from the first return spring 68. The top part of the torsion plate 685 protrudes from the top of the storage box 681.

[0054] During operation, when it is necessary to adjust the distance between the two grinding discs 51, the maintenance personnel only need to twist the twisting disc 685. Then, the twisting disc 685 drives the lead screw 684 to rotate, realizing the relative movement of the twisting disc 685 and the moving block 682. This causes the moving blocks 682 on both sides to slowly move closer, further compressing the first return spring 68, so that the grinding discs 51 on both sides and the brake disc 5 can achieve a good braking effect. Moreover, the first return spring 68 can be replaced when it is deformed after long-term use.

[0055] Example 4:

[0056] As one embodiment of the present invention, such as Figure 2 , Figure 9 and Figure 10As shown, the top of the connecting plate 3 is equipped with an air pump assembly 7 for the operation of the drive control assembly 6. The air pump assembly 7 includes a through box 72 installed at the bottom of the connecting plate 3. A pump pipe 71 is installed through the top of the through box 72, penetrating the top of the connecting plate 3. The end of the pump pipe 71 away from the connecting plate 3 is connected to a power assist pump inside the driver's cab. A foot pedal for easy driver foot switch is installed on the power assist pump. One end of the pump pipe 71 extends into the interior of the through box 72 and is equipped with a branch pipe head 73. Two piston grooves 74 are opened in the bottom cavity of the through box 72. The inner sides of the two piston grooves 74 are connected to the branch pipe head 73 through a connecting pipe. A piston plate 75 is slidably connected to the inner side of the piston grooves 74. A piston rod 76 is installed on the opposite side of the two piston plates 75. One end of the piston rod 76 extends out of the outside of the through box 72 and is equipped with an arc-shaped pressing part 77. A fixing rod 6 is installed between the drive blocks 69 on the front and rear sides. 12. The inner side of the arc-shaped pressing part 77 is pressed against the outer side of the fixed rod 612. A second return spring 78 is sleeved on the outer side of the piston rod 76 and the inner side of the piston groove 74. An oil storage assembly 79 is installed inside the piston rod 76. The oil storage assembly 79 includes a hemispherical elastic shell 791, a push rod 792, a sponge rod 793, an oil storage cavity 794, and a ball bearing 795. The push rod 792 is slidably installed at the center of the piston rod 76 and the piston plate 75. One end of the push rod 792 is fixedly connected to the hemispherical elastic shell 791, and the other end of the push rod 792 abuts against the sponge rod 793 disposed inside the piston rod 76. An oil storage cavity 794 is provided on the piston rod 76, and the oil storage cavity 794 communicates with the sponge rod 793. A plurality of balls bearing 795 are installed inside the arc-shaped pressing part 77, and the middle ball bearing 795 communicates with the sponge rod 793.

[0057] During operation, when the driver presses the pedal, the pedal compresses the air in the power steering pump, causing the air inside to enter the through-box 72 through the pump pipe 71. The compressed air then enters the connecting pipes on both sides through the branch pipe head 73. At this time, the air in the connecting pipes on both sides pushes the piston plate 75 to move along the piston groove 74, so that the piston rod 76 and the arc-shaped pressing part 77 press the fixing rod 612 to a certain distance. Furthermore, when the gas inside the branch pipe head 73 enters the two sides, the gas compresses the hemispherical elastic shell 791, causing the hemispherical elastic shell 791 to drive the push rod 792 to move. The push rod 792 compresses the sponge rod 793, allowing the oil inside the sponge rod 793 to enter the surface of the ball bearing 795, thereby reducing noise during braking and providing good lubrication. After lubrication is completed, the hemispherical elastic shell 791 returns to its original shape, allowing the sponge rod 793 to resume oil absorption.

[0058] Example 5:

[0059] As one embodiment of the present invention, such as Figure 1 and Figure 2As shown, a shock-absorbing assembly 8 for shock absorption is provided between the locomotive underframe 2 and the wheel 4. The shock-absorbing assembly 8 includes a wheel frame 81 rotatably connected to the bottom of the locomotive underframe 2, a drive rod 40 rotatably connected to the middle of the wheel frame 81 on the wheel 4, a third return spring 82 connected between the top of the wheel frame 81 and the locomotive underframe 2, a telescopic rod 83 rotatably connected to the end of the wheel frame 81 away from the locomotive underframe 2, the moving end of the telescopic rod 83 rotatably connected to the locomotive underframe 2, and an L-shaped plate 84 installed on the side of the wheel frame 81 near the wheel 4. The vertical end of the L-shaped plate 84 is installed at the bottom of the rotating part 62.

[0060] When wheel 4 experiences bumps during driving, the wheel frame 81 and drive rod 40 work together with the third return spring 82 and telescopic rod 83 to achieve shock absorption for wheel 4. Moreover, when the wheel frame 81 rotates up and down slightly, it drives the rotating part 62 to rotate synchronously through the L-shaped plate 84, so that the grinding disc 51 moves synchronously with the brake disc 5 on the drive rod 40.

[0061] Working principle: This is used in the braking system of dual-type mining battery locomotives. When in use:

[0062] When the driver presses the pedal, the pedal compresses the air in the power steering pump, causing the air inside to enter the through-box 72 through the pump pipe 71. Then, the compressed air enters the connecting pipes on both sides through the branch pipe head 73. At this time, the air in the connecting pipes on both sides pushes the piston plate 75 to move along the piston groove 74, so that the piston rod 76 and the arc-shaped pressing part 77 press the fixing rod 612 to a certain distance. Then, when the drive block 69 moves upward, it drives the first passive block 610 and the second passive block 611 connected to it to move. The mating blocks 67 on both sides achieve relative movement under the pressure of the first passive block 610 and the second passive block 611, so that the grinding disc 51 on the first rotating plate 65 and the second rotating plate 66 moves closer to the outside of the brake disc 5, so as to increase the friction between the grinding disc 51 and the brake disc 5, thereby achieving the braking effect on the brake disc 5.

[0063] When the grinding disc 51 needs to be replaced, the maintenance personnel only need to use a wrench to turn the main bolts 93 on both sides. The main bolts 93 on both sides drive the first bolt 94 to loosen, so that the first bolt 94 disengages from the limit support block 511 and the first rotating plate 65, thereby realizing the quick disassembly and installation of the grinding disc 51. At the same time, during the rotation of the first bolt 94, the first connecting gear 95 is driven to rotate, so that the second bolts 97 at both ends of the first connecting gear 95 rotate synchronously, thereby disengaging the rotating plate 91 from the first rotating plate 65 or the second rotating plate 66. Then the maintenance personnel can rotate the rotating plate 91 to disassemble the grinding disc 51. During the rotation of the first bolt 94 and the second bolt 97, the pressing plate 96 is driven to slide along the upper limit of the limit fixing rod 99, which helps to ensure that the first connecting gear 95 and the second connecting gear 98 remain engaged. When the maintenance personnel disassemble the grinding disc 51, there is no need to lift the grinding disc 51 at all.

[0064] When it is necessary to adjust the distance between the two grinding discs 51, the maintenance personnel only need to twist the twisting disc 685, and then the twisting disc 685 drives the lead screw 684 to rotate, so that the twisting disc 685 and the moving block 682 move relative to each other, thereby causing the moving blocks 682 on both sides to slowly move closer, so that the first return spring 68 is further compressed, so that the two grinding discs 51 and the brake disc 5 can achieve a good braking effect. Moreover, the first return spring 68 can be replaced when it is deformed after long-term use.
