Description

Technical Field

[0001] The invention relates to the technical field of trackless rubber-tyred vehicles, and more specifically to a braking protection device for trackless rubber-tyred vehicles. Background Art

[0002] Rubber-tyred trackless vehicles (also known as rubber-tyred trackless transport vehicles) are vehicles suitable for mining transportation operations and are widely used in mining, tunnel construction, geological exploration and other scenarios. Since rubber-tyred trackless vehicles often operate in complex working conditions such as mines and tunnels, a reliable braking system is crucial to ensure the safety of operators and the smooth completion of operations.

[0003] A trackless rubber-tyred vehicle operating in an underground coal mine has to brake frequently during operation due to long-term short-distance transportation. In addition, there are many and long slopes in the underground mine, which requires the braking system to be in a braking state for a long time. This can easily cause the temperature of the braking equipment to be too high, thereby reducing the braking performance and seriously threatening the overall safety performance of the trackless rubber-tyred vehicle. In addition, traditional braking equipment, such as drum brake systems, lack effective cooling and heat dissipation functions and cannot ensure the safety of the braking system in an overloaded working environment. Therefore, it is necessary to propose a brake protection device for a trackless rubber-tyred vehicle to solve the above problems. Summary of the invention

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

[0019] A cooling mechanism capable of spraying cooling water is installed on the brake disc of a traditional drum brake. When braking, the cooling mechanism starts to spray cooling water on the surface of the brake drum, thereby reducing the temperature of the brake drum and stabilizing the braking effect of the brake. In addition, a collection box is installed at the bottom of the brake disc to collect the cooling water flowing down the brake drum to prevent the cooling water from dripping onto the pothole road surface, causing the road to become muddy and resulting in a deterioration in the braking effect of the rubber-tyred trackless vehicle.

[0020] A water splashing mechanism is arranged inside the collection box. When the rubber-tyred trackless vehicle brakes, not only can the brake shoe push the lifting mechanism to lift the water splashing mechanism so that the water splashing mechanism reaches a position where the push rod can resist, but also the brake drum drives a number of levers to rotate, thereby driving the push rod to intermittently resist the water splashing plate, and then driving the water splashing plate to move up and down, splashing the cooling water in the collection box onto the brake drum, increasing the cooling method, further improving the cooling effect, and thus improving the braking effect of the drum brake; the lifting mechanism is also provided with a plurality of anti-interference mechanisms, which can open the water outlet when the water splashing plate swings down, thereby increasing the water flow rate, reducing the water resistance, and reducing the water body fluctuation.

[0021] The swing of the water splashing plate can also drive the cleaning brush to sweep up and down inside the side plate through the first connecting rod to clean the filter net and remove impurities to ensure the normal operation of the filter net. The filter mechanism filters impurities in the water, and the deposited impurities need to be cleaned in time. Therefore, when braking, the rise of the water splashing mechanism can push the sealing door to close the sewage outlet and retract the sewage push plate, thereby ensuring that the bottom of the collection box does not leak, which is helpful for collecting rainwater; after braking, the water splashing mechanism descends and can also pull the sealing door to open the sewage outlet. At the same time, the sliding rod pushes the sewage push plate to slide, and the impurities deposited near the filter net are pushed out from the sewage outlet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1-Figure 9 As shown, the present invention discloses a brake protection device for a trackless rubber-tyred vehicle, comprising a brake mechanism 1, wherein the brake mechanism 1 comprises a brake drum 11, a brake disc 12 is installed on the side of the brake drum 11, two brake shoes 17 are symmetrically installed inside the brake disc 12, and a brake pad 18 is installed on the outer side of the brake shoe 17;

[0035] A cooling mechanism 2 is installed on the top surface of the brake disc 12. The cooling mechanism 2 includes a diverter block 21 installed on the top surface of the brake disc 12. A water outlet pipe 23 is connected to the top surface of the diverter block 21. A cooling nozzle 24 is installed at the end of the water outlet pipe 23.

[0036] A collecting mechanism 3 is installed at the bottom of the brake disc 12, and the collecting mechanism 3 includes a collecting box 31 installed at the bottom of the brake disc 12, and a water pump 32 is installed on the side of the collecting box 31. The input end of the water pump 32 is connected to the interior of the collecting box 31, and the output end of the water pump 32 is connected to a water supply pipe 33. The water supply pipe 33 is installed on the cylindrical surface of the brake disc 12, and the end of the water supply pipe 33 is connected to the side of the diverter block 21.

[0037] The brake drum 11 is mounted on the tire, and the brake disc 12 is mounted on the axle or steering knuckle. The brake disc 12 remains stationary, and the brake drum 11 rotates with the tire. Half of each brake shoe 17 is in the brake drum 11, the width of the brake pad 18 is less than half of the width of the brake shoe 17, and the brake pad 18 is in the brake drum 11. When the trackless rubber-tyred vehicle brakes, the brake shoe 17 drives the brake pad 18 to contact the inner wall of the brake drum 11 to complete the braking. For frequent braking in the mine tunnel and long-term braking on the slope, the brake drum 11 and the brake pad 18 will cause the brake drum 11 to heat up seriously due to long-term friction, thereby reducing the braking performance of the brake pad 18. Therefore, whenever braking, the external water source enters the diverter block 21 through the water inlet pipe 22, and then enters the cooling nozzle 24 through the water outlet pipe 23. The cooling nozzle 24 sprays water evenly on the brake drum 11 to reduce the temperature of the brake drum 11, thereby ensuring the braking effect.

[0038] The water sprayed on the surface of the brake drum 11 may flow downstream and drip from the bottom of the brake drum 11 onto the road surface of the mine. However, since the road surface of the mine is mostly soft, the cooling water drips onto the dirt road for a long time, which is not only easy to pollute the wheels, but also more likely to cause the rubber-tyred vehicle to slip, thereby reducing the braking effect of the rubber-tyred vehicle and causing a waste of water resources. Therefore, a collecting mechanism 3 is provided at the bottom of the brake disc 12, and the cooling water flowing downstream will flow into the collecting box 31 installed at the bottom of the brake disc 12, and finally be re-pumped into the diverter block 21 through the water pump 32 and the water supply pipe 33, and sprayed on the brake drum 11 again by the cooling nozzle 24, which greatly improves the utilization rate of water resources (one end of the top surface of the collecting box 31 is installed at the bottom of the brake drum 12, and the other end of the collecting box 31 is at the bottom of the brake disc 11, but has no contact with the brake disc 11).

[0039] Example 2: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9 The brake mechanism 1 also includes two brackets 13 and two support shafts 15 symmetrically installed on the inner wall of the brake disc 12. A brake wheel cylinder 14 is installed on the bracket 13. An arc plate 16 is fixed to the inner side of each brake shoe 17. One end of the arc plate 16 is rotatably connected to the corresponding support shaft 15, and the other end of the arc plate 16 is rotatably connected to the output end of the corresponding brake wheel cylinder 14. Two first springs 19 are symmetrically connected to the two ends of the two arc plates 16.

[0040] The cooling mechanism 2 further includes a water inlet pipe 22 connected to the other side of the diverter block 21 .

[0041] The collecting mechanism 3 further includes a sewage outlet 34 which penetrates through the bottom of the collecting box 31 .

[0042] A pushing mechanism 4 is installed inside the brake drum 11, and the pushing mechanism 4 includes a moving ring 41 slidably connected to the inner wall of the brake drum 11, the moving ring 41 and the brake drum 11 are elastically connected through a plurality of second springs 42 in an annular array, and a plurality of levers 43 are arranged in an annular array on the side of the moving ring 41, a pressure block 44 is slidably connected to the top of the collection box 31, a push rod 45 is fixed to the bottom of the pressure block 44, a third spring 46 is sleeved on the push rod 45, and the push rod 45 is elastically connected to the inside of the collection box 31 through the third spring 46.

[0043] A lifting mechanism 5 is installed inside the collecting box 31, and the lifting mechanism 5 includes two outer shells 51 symmetrically fixed to the inner bottom surface of the collecting box 31. A lifting rack 52 is slidably connected inside the outer shell 51, and a pressure rod 53 is fixed to the top surface of the lifting rack 52, and the pressure rod 53 passes through the bottom of the brake disc 12. A fourth spring 54 is installed inside the outer shell 51, and the lifting rack 52 is elastically connected to the outer shell 51 through the fourth spring 54. A gear 55 is rotatably connected inside the outer shell 51, and the gear 55 is meshingly connected to the lifting rack 52.

[0044] A water splashing mechanism 6 is installed inside the collection box 31, and the water splashing mechanism 6 includes a lifting gear plate 61 slidably connected to the inside of the outer shell 51, and both ends of the lifting gear plate 61 are meshed and connected with corresponding gears 55. A rotating seat 62 is installed on the top surface of the lifting gear plate 61, and a rotating sleeve 63 is rotatably connected to the rotating seat 62. A first torsion spring 64 is installed in the rotating sleeve 63, and a water splashing plate 65 is fixed to the top surface of the rotating sleeve 63. Two anti-pillars 66 are symmetrically fixed to the side of the lifting gear plate 61, and a cylinder 67 is fixed to the side of the anti-pillar 66.

[0045] When braking, the wheel cylinder 14 on the bracket 13 works, pushing one end of the arc plate 16, and the other end of the arc plate 16 rotates around the support shaft 15, and the arc plate 16 stretches the first spring 19. At the same time, the arc plate 16 drives the brake pad 18 to contact the inner wall of the brake drum 11 through the brake shoe 17, and the brake drum 11 is quickly decelerated by friction, so that the wheel stops. The first spring 19 installed on the arc plate 16 can drive the arc plate 16 to reset when the wheel cylinder 14 stops working, and the arc plate 16 drives the brake shoe 17 and the brake pad 18 to reset.

[0046] Although the cooling water sprayed on the top of the brake drum 11 by the cooling nozzle 24 can achieve a good cooling effect, once the temperature of the brake drum 11 is too high, the cooling water sprayed on the surface of the brake drum 11 will evaporate quickly. The position on the brake drum 11 where the cooling water was originally sprayed needs to rotate one circle before the cooling water can be sprayed again, and the cooling effect is limited. Therefore, a water splashing mechanism 6 is installed in the collection box 31. When braking continuously, the brake shoe 17 first contacts the pressure rod 53, pushing the pressure rod 53 into the collection box 31. The pressure rod 53 drives the lifting rack 52 to slide in the shell 51, compressing the fourth spring 54 while driving the gear 55 to rotate. The gear 55 drives the lifting gear plate 61 to rise from the bottom of the shell 51, and the lifting gear plate 61 drives the water splashing plate 65 to rise to a certain position (the first torsion spring 64 inside the rotating sleeve 63 keeps the water splashing plate 65 as attached without being affected by external forces). Figure 3 status shown).

[0047] During this process, the brake shoe 17 drives the brake pad 18 to contact the inner wall of the brake drum 11. At the same time, the side of the brake pad 18 contacts and pushes the movable ring 41 to slide in the brake drum 11. The movable ring 41 compresses the second spring 42 and drives the lever 43 to slide from the brake drum 11 to the collection box 31. Since the brake drum 11 rotates with the wheel, the brake drum 11 drives the lever 43 on the movable ring 41 to rotate. The lever 43 contacts the pressure block 44 once at a certain interval, so that the pressure block 44 drives the push rod 45 to slide into the collection box 31. At the same time, the movable ring 41 compresses the third spring 46. When the lever 43 does not contact the pressure block 44, the third spring 46 drives the pressure block 44 and the push rod 45 to reset. Each time the push rod 45 slides into the collection box 31, it contacts the top surface of one raised end of the water splashing plate 65, causing the other end of the water splashing plate 65 to move upward. Cooling water is collected in the collection box 31. During the movement of the water splashing plate 65, the cooling water can be splashed on the bottom of the brake drum 11, thereby further cooling the brake drum 11 and further enhancing the cooling effect of the brake drum 11, thereby improving the braking effect.

[0048] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9 A filtering mechanism 7 is installed inside the collecting box 31, and the filtering mechanism 7 includes two side panels 71 symmetrically installed at one end of the collecting box 31, a filter screen 72 is installed between the side panels 71, and a cleaning brush 73 is slidably connected between the side panels 71. A supporting rod 74 is installed on the inner bottom surface of the collecting box 31, and a first connecting rod 75 is rotatably connected to the top end of the supporting rod 74. One end of the first connecting rod 75 is rotatably connected to the water splashing plate 65, and the other end of the first connecting rod 75 is rotatably connected to the cleaning brush 73.

[0049] A sewage discharge mechanism 8 is installed inside the collecting box 31, and the sewage discharge mechanism 8 includes two limiting sleeves 81 symmetrically installed on the inner bottom surface of the collecting box 31, a sliding rod 82 is slidably connected inside the limiting sleeve 81, one end of the sliding rod 82 is installed with a first wedge block 83, and the abutment column 66 abuts against the first wedge block 83, a fifth spring 84 is installed inside the limiting sleeve 81, the first wedge block 83 is elastically connected to the limiting sleeve 81 through the fifth spring 84, and a sewage pushing plate 85 is fixed to the other end of the sliding rod 82, a limiting box 86 is installed on one side of the limiting sleeve 81, a second wedge block 87 is slidably connected inside the limiting box 86, a sixth spring 88 is installed inside the limiting box 86, the second wedge block 87 is elastically connected to the limiting box 86 through the sixth spring 88, and the side of the second wedge block 87 is rotatably connected to the second connecting rod 89, and two inclined blocks 892 are symmetrically installed on the inner bottom surface of the collecting box 31, the tops of the two inclined blocks 892 are slidably connected to the sealing door 891, and the other end of the second connecting rod 89 is rotatably connected to the sealing door 891.

[0050] The rubber-tyred trackless vehicle travels in the mine tunnel for a long time to transport coal and other resources. It is inevitable that dust, slag and other impurities are attached to the surface of the brake drum 11. The cooling water collected by the collection box 31 and flowing down from the brake drum 11 may carry impurities. Obviously, the cooling water mixed with impurities cannot be directly returned to the cooling mechanism 2 for reuse. Therefore, a filtering mechanism 7 is provided in the collection box 31, which can filter the cooling water. The cooling water can be absorbed by the water pump 32 only after passing through the filter net 72.

[0051] During the swinging process of the water splashing plate 65, one end of the first connecting rod 75 can be driven to swing, so that the middle part of the first connecting rod 75 rotates at the top end of the support rod 74, and the other end of the first connecting rod 75 swings up and down, thereby driving the cleaning brush 73 to sweep up and down between the two side plates 71, cleaning the impurities filtered on the filter net 72, and ensuring the filtering effect of the filter net 72.

[0052] Initially (if attached Figure 8As shown in the figure, when the lifting gear plate 61 is at the bottom of the housing 51), the support column 66 contacts the first wedge block 83, and the cylinder 67 contacts the second wedge block 87. When the lifting gear plate 61 is lifted, the support column 66 is also driven to rise, and the support column 66 drives the cylinder 67 to rise, and the support column 66 no longer contacts the first wedge block 83. Under the push of the fifth spring 84, the slide bar 82 drives the first wedge block 83 and the dirt pushing plate 85 to slide, and the first wedge block 83 slides in the direction of the support column 66, and the dirt pushing plate 85 slides from the side of the sewage outlet 34 to the vicinity of the tilting block 892, so that the dirt pushing plate 85 is away from the sewage outlet 34. During this process, the cylinder 67 no longer contacts the second wedge block 87, and the sixth spring 88 pushes the second wedge block 87 away from the support column 66. The second wedge block 87 pushes the sealing door 891 from the inclined block 892 to the direction close to the sewage outlet 34 through the second connecting rod 89. The sealing door 891 slides down from the inclined block 892, changes from inclined sliding to horizontal sliding, and finally engages in the sewage outlet 34, closing the sewage outlet 34. Then the collection box 31 plays the role of collecting cooling water. When the braking is over, during this process, some impurities are filtered in the collection box 31 and accumulated near the filter screen 72, such as on the sealing door 891. At this time, the brake shoe 17 no longer contacts the pressure rod 53, and the fourth spring 54 pushes the lifting rack 52 to rise, and the lifting rack 52 drives the pressure rod 53 to reset, and at the same time drives the lifting gear plate 61 back to the bottom of the shell 51 through the gear 55, and the lifting gear plate 61 drives the support column 66 to descend, and the support column 66 drives the cylinder 67 to descend, and the cylinder 67 squeezes the second wedge block 87 to slide toward the direction close to the support column 66, and the second wedge block 87 pulls up the sealing door 891 through the second connecting rod 89, and slides back to the tilting block 892, thereby opening the sewage outlet 34. After the sealing door 891 slides onto the tilting block 892, it changes from horizontal to tilted toward the sewage outlet 34, which helps the impurities accumulated on the top surface of the sealing door 891 to roll off quickly, thereby avoiding excessive impurities deposited on the top surface of the sealing door 891 and making it difficult to remove; the support column 66 squeezes the first wedge block 83, and the first wedge block 83 compresses the fifth spring 84, while pushing the sewage pushing plate 85 close to the sewage outlet 34 through the sliding rod 82, and the sewage pushing plate 85 can push the impurities accumulated on the bottom surface of the collection box 31 out of the sewage outlet 34.

[0053] Example 4: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 9 The water splashing plate 65 is provided with an anti-disturbance mechanism 9, which includes a plurality of water openings 91 penetrating the water splashing plate 65. The water splashing plate 65 is also provided with a plurality of opening and closing plates 92 rotatably connected thereto at equal intervals, and each opening and closing plate 92 is rotatably connected to the corresponding water opening 91, and a second torsion spring 93 is installed at both ends of each opening and closing plate 92.

[0054] The splashing plate 65 has a downward swinging motion during the splashing process. If the splashing plate 65 is a solid flat plate, when it swings downward, the splashing plate 65 may cause water splashing and cause the water in the collection box 31 to fluctuate violently. Therefore, a plurality of water inlets 91 are provided on the splashing plate 65, and an opening and closing plate 92 is installed on the water inlets 91. The second torsion springs 93 on both sides of the opening and closing plate 92 can ensure that the opening and closing plate 92 closes the water inlets 91 without being acted upon by external forces. When swinging, the opening and closing plate 92 rotates when hit by water, thereby opening the water outlet 91 and storing force in the second torsion spring 93. Water flows through the water outlet 91, which can greatly reduce the impact force of the water flow on the water splashing plate 65 and reduce the amplitude of water fluctuation. When the water splashing plate 65 swings upward to splash water, the second torsion spring 93 drives the opening and closing plate 92 to rotate, and the water pressure causes the opening and closing plate 92 to quickly close the water outlet 91, so that the water flow can be raised more efficiently to splash water on the brake drum 11.
