Description

Technical Field

[0001] The utility model belongs to the technical field of tractor tracks, and in particular relates to tractor tracks. Background Art

[0002] Tractor track refers to a track system designed and used specifically for tractors. This type of track is usually used in factories, warehouses, mines or other places where heavy equipment needs to be moved and materials need to be transported. Tractor track consists of a series of track beams, track plates, connectors, etc., which can carry the tractor and the cargo it tows and guide it to move along a predetermined path;

[0003] Tractor tracks play an important role in complex environments such as coal mines. Common tractor tracks are usually connected by bolts, which are convenient for quick disassembly and track adjustment. The connecting bolts of the tracks usually need to be regularly coated with bolt protective grease for protection;

[0004] Because the environment of mines is relatively complex, even protective grease with anti-pollution performance may be gradually contaminated due to long-term exposure and harsh environmental conditions. Common pollutants include water and dust. These pollutants may enter the protective grease through direct contact or indirect penetration, causing its performance to deteriorate or fail. The existing rail connection structure may lack measures or methods to keep the bolt working environment clean for a long time.

[0005] In order to solve the above problems, a tractor track is proposed in the present application. Utility Model Content

[0006] In view of the problems in the related technology, the utility model proposes a track connection structure and a tractor track to overcome the above technical problems existing in the existing related technology.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A tractor track comprises a track body and a track connection structure, wherein the track connection structure comprises a fishplate, wherein an inner cavity thread of the fishplate is penetrated by a track bolt, and a nut is threadedly connected to an outer surface of the track bolt; the track connection structure is arranged on the outer surface of the track body, a vibration sensor is installed on a side of the track body close to the fishplate, a wire is installed on a side of the vibration sensor away from the fishplate, a micro air pump is installed on a side of the track body close to the fishplate, an air inlet pipe is installed on an input end of the micro air pump, an exhaust pipe is installed on an output end of the micro air pump, and a shunt pipe is installed on an end of the exhaust pipe away from the micro air pump.

[0009] A support block is fixedly connected to one side of the track body close to the fishtail plate, and an end of the support block away from the fishtail plate is welded to the outer surface of the shunt pipe. By setting the support block, the support block can provide supporting force for the shunt pipe, thereby avoiding accidental movement of the shunt pipe due to external force during operation, and avoiding accidental changes in the cleaning position of the fishtail plate surface.

[0010] A positioning frame is fixedly connected to one side of the track body close to the fishplate, and the inner surface height of the positioning frame is equal to the height of the fishplate. By setting the positioning frame, the fishplate is inserted into the positioning frame at an adjacent position to assist in quickly aligning two adjacent track bodies, thereby avoiding large errors when connecting the two adjacent track bodies.

[0011] A load-bearing block is fixedly connected to a side of the positioning frame away from the fishtail plate, a reset telescopic rod is detachably mounted on the outer surface of the load-bearing block, a reset spring is wound around the outer surface of the reset telescopic rod, a cleaning sponge block is fixedly connected to the telescopic end of the reset telescopic rod, and by arranging the load-bearing block reset telescopic rod reset spring and the cleaning sponge block, when the cleaning sponge block is subjected to wind blowing from the opposite direction, the cleaning sponge block is forced to compress the reset telescopic rod and the reset spring, and when the wind blowing from the cleaning sponge block disappears, the cleaning sponge block moves along a horizontal straight line under the action of the reset telescopic rod and the reset spring, and the moving cleaning sponge block can clean the stains on the surface of the adjacent fishtail plate, so that the fishtail plate can be kept clean for as long as possible.

[0012] A threaded hole is provided on the side of the load-bearing block away from the nut, and a threaded round block is threadedly connected to the inner cavity of the load-bearing block. The outer surface of the threaded round block is welded to the side of the reset telescopic rod close to the load-bearing block. By setting the threaded hole and the threaded round block, the threaded round block can be gradually separated from the load-bearing block by rotating counterclockwise under force. When the threaded round block completely leaves the threaded hole, the operator can quickly replace the reset telescopic rod and the threaded round block as a whole, which is convenient for quickly replacing the cleaning sponge block that is severely worn.

[0013] In summary, the technical effects and advantages of the utility model are as follows:

[0014] 1. The vibration of the tractor track body can trigger the micro air pump to work through the vibration sensor and the wire. After the micro air pump is started, it can intermittently release gas to the surface of the fishplate through the exhaust pipe and the shunt pipe. The airflow passing through the surface of the fishplate can clean dust and moisture, so as to keep the track bolts as dry and clean as possible, and minimize the maintenance and replacement frequency of the track bolts.

[0015] 2. The tractor track has an airflow opposite to the cleaning sponge block which can drive the cleaning sponge block to compress the resetting telescopic rod and the resetting spring. When the intermittent airflow opposite to the cleaning sponge block stops temporarily, the cleaning sponge block can clean the adjacent fishplate under the action of the resetting telescopic rod and the resetting spring, so as to keep the fishplate clean as much as possible, prolong the working life of the fishplate as much as possible and reduce the probability of damage to the fishplate as much as possible.

[0022] 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, rather than all of the embodiments.

A micro air pump 7 is installed on one side of the track body 2 close to the fishtail plate 1, and one end of the wire 6 away from the vibration sensor 5 is fixedly connected to the inner cavity of the micro air pump 7; when the tractor passes through the track body 2 and generates vibration, the vibration sensor 5 can detect the vibration and transmit a signal to the micro air pump 7 through the wire 6, and the micro air pump 7 quickly turns on its internal switch after receiving the signal; and after the vibration generated by the tractor passing through the track body 2 disappears, the micro air pump 7 no longer receives the signal and turns off the internal switch, wherein the signal transmission method between the vibration sensor 5 and the micro air pump 7 is the existing technology, and the circuit connection method of the vibration sensor 5, the wire 6 and the micro air pump 7 can be arranged according to actual conditions.

[0024] Reference Figure 1 An air inlet pipe 8 is installed at the input end of the micro air pump 7, an exhaust pipe 9 is installed at the output end of the micro air pump 7, and a shunt pipe 10 is installed at the end of the exhaust pipe 9 away from the micro air pump 7; after the internal switch of the micro air pump 7 is turned on, the micro air pump 7 can transport air to the shunt pipe 10 through the air inlet pipe 8 and the exhaust pipe 9, and because the shunt pipe 10 is a three-way pipe, the air generated by the micro air pump 7 can pass through the surface of the fishtail plate 1 more evenly, which is convenient for regularly cleaning the dust and impurities around the track bolts 3, and for keeping the track bolts 3 as dry and clean as possible, and for avoiding the bolt protective grease on the surface of the track bolts 3 from being quickly contaminated in a humid environment, thereby minimizing the maintenance and replacement frequency of the track bolts 3.

[0025] Reference Figure 1 A support block 11 is fixedly connected to one side of the track body 2 close to the fishplate 1, and the end of the support block 11 away from the fishplate 1 is welded to the outer surface of the shunt pipe 10. The support block 11 can provide additional support force for the shunt pipe 10, and try to avoid the support block 11 from being easily moved to its working position due to external force interference, and try to ensure the working range of the support block 11.

[0026] Reference Figure 1 and Figure 3A positioning frame 12 is fixedly connected to one side of the track body 2 close to the fish plate 1, and the inner surface height of the positioning frame 12 is equal to the height of the fish plate 1, and the inner surface of the positioning frame 12 fits the outer surface of the fish plate 1; when two adjacent track bodies 2 need to be connected to each other, the fish plate 1 can be inserted into the positioning frame 12 on the surface of the adjacent track body 2 to guide the two adjacent track bodies 2, so as to facilitate the rapid alignment of the two adjacent track bodies 2 and assist in the connection.

[0027] Reference Figure 1 and Figure 4 A load-bearing block 13 is fixedly connected to the side of the positioning frame 12 away from the fishplate 1, and a reset telescopic rod 14 is detachably installed on the outer surface of the load-bearing block 13, and the telescopic length of the reset telescopic rod 14 is less than the length of the fishplate 1; a reset spring 15 is wound around the outer surface of the reset telescopic rod 14, and the telescopic length of the reset spring 15 is equal to the telescopic length of the reset telescopic rod 14, and a cleaning sponge block 16 is fixedly connected to the telescopic end of the reset telescopic rod 14. When the two track bodies 2 are connected to each other, the cleaning sponge block 16 can move along the surface of the adjacent fishplate 1. When the cleaning sponge block 16 is affected by the opposite wind, the cleaning sponge block 16 is forced to compress the reset telescopic rod 14 and the reset spring 15. When the wind opposite to the cleaning sponge block 16 disappears temporarily, the cleaning sponge block 16 quickly cleans the dust and stains on the surface of the adjacent fishplate 1 under the action of the reset telescopic rod 14 and the reset spring 15.

[0028] Reference Figure 4 A threaded hole 17 is provided on the side of the load-bearing block 13 away from the nut 4, and a threaded round block 18 is threadedly connected to the inner cavity of the load-bearing block 13, and the outer surface of the threaded round block 18 is welded to the side of the reset telescopic rod 14 close to the load-bearing block 13. The reset telescopic rod 14 is subjected to force to rotate counterclockwise to drive the threaded round block 18 to move away from the load-bearing block 13. When the threaded round block 18 is completely separated from the threaded hole 17, the operator can quickly remove the reset telescopic rod 14, the reset spring 15 and the cleaning sponge block 16 as a whole and replace the damaged parts.

[0029] Working principle: First, the two track bodies 2 can be inserted into the positioning frame 12 on the surface of the adjacent track body 2 through the fishplate 1 for alignment, and then the operator connects and fixes the two horizontally adjacent track bodies 2 by rotating the track bolts 3 through the fishplate 1 and the track body 2. The tractor can generate vibration when passing through the track body 2, and the vibration sensor 5 on the surface of the track body 2 detects the vibration. When the track body 2 vibrates, the vibration sensor 5 can control the micro air pump 7 to start through the wire 6. When the vibration on the surface of the track body 2 disappears, the micro air pump 7 no longer receives the signal and stops working. After the micro air pump 7 is started, it can transport air to the shunt pipe 10 through the intake pipe 8 and the exhaust pipe 9. Because the shunt pipe 10 is a three-way pipe, the shunt pipe 10 can release gas to the surface of the fishplate 1 more comprehensively, and the airflow passing through the surface of the fishplate 1 can clean dust and moisture, so as to keep the track bolts 3 as dry and clean as possible, and minimize the maintenance and replacement frequency of the track bolts 3.
