Description

Technical Field

[0001] This utility model relates to the field of vehicle transmission protection technology, specifically a splash protection device for the drive shaft of a mining vehicle. Background Technology

[0002] The strong market demand for mining vehicles is mainly due to the continuous demand from the mining industry for efficient, safe, and durable equipment. As mining vehicles operate in complex underground conditions for extended periods, their transmission systems (especially the front drive shaft) are prone to breakage due to the alternating impact loads.

[0003] Existing technology, such as the patent application "CN211000776U", discloses a protective device for the drive shaft and braking system of a mining transport vehicle. This device includes two longitudinal fixing frames welded to the inner side of the vehicle's main beam. These longitudinal fixing frames are symmetrically distributed on both sides of the drive shaft. Protective baffles are installed on the longitudinal fixing frames, and transverse connecting plates are welded to the protective baffles. Semi-circular protective covers are provided above and below the transverse connecting plates, with the drive shaft located in the middle of the upper and lower protective covers. When the drive shaft cross axle malfunctions and falls off, the drive shaft can only rotate within a certain range, preventing damage to other components. This protects the vehicle's braking system from being affected, ensuring the vehicle can stop safely and promptly in case of a malfunction, thereby protecting the driver's safety and preventing damage to equipment and property, and avoiding major accidents causing injury.

[0004] Existing protective devices, while limiting the displacement range of the drive shaft through longitudinal fixing frames and semi-circular protective covers, still have the following drawbacks: 1) The protective cover is not convenient or quick to disassemble, and is time-consuming and labor-intensive; 2) The rigid protective structure lacks a buffer mechanism, and stress concentration easily occurs at the connection between the drive shafts during vehicle operation, leading to drive shaft breakage. Therefore, we propose a splash protection device for the drive shaft of mining vehicles. Utility Model Content

[0005] The purpose of this invention is to solve the problems of time-consuming and labor-intensive removal of protective covers and the lack of buffering in rigid protective structures, and to provide a splash protection device for the drive shaft of mining vehicles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A splash protection device for the drive shaft of a mining vehicle includes a front drive shaft installed at the output end of the front drive axle assembly and power transmission of the vehicle. A top beam mounting protective plate is provided on the outer wall of the front drive shaft. A shaft rod is fixedly installed on the inner wall of the bearing end of the top beam mounting protective plate. A bottom mounting protective plate is rotatably installed on the outer wall of the shaft rod. A quick-release device is provided on the outer walls of the top beam mounting protective plate and the bottom mounting protective plate. The quick-release device includes an outer shaft block, which is fixedly installed on the outer wall of the bottom mounting protective plate. A fixing rod is fixedly installed on the inner wall of the outer shaft block. A clamping plate is rotatably installed on the outer wall of the fixing rod. A clamping block is fixedly installed on the outer wall of the top beam mounting protective plate.

[0008] Preferably, a sealing strip one is fixedly installed on the bottom surface of the top beam mounting protective plate, and a sealing strip two is fixedly installed on the side of the bottom mounting protective plate near the sealing strip one.

[0009] Preferably, the card plate is L-shaped, and the top of the card plate is an inverted triangle. The card plate is elastic, and the top of the card block is a right triangle. The inverted triangle at the top of the card plate is located on the movement trajectory of the right triangle at the top of the card block.

[0010] Preferably, the inner walls of the top beam mounting protective plate and the bottom mounting protective plate are provided with a buffer device. The buffer device includes columnar rods, arc-shaped limiting plates, arc-shaped sliding plates, arc-shaped grooves, springs, rotating shafts, and rollers. There are four columnar rods, which are respectively fixedly installed on the inner walls of the top beam mounting protective plate and the bottom mounting protective plate. The arc-shaped limiting plates are fixedly installed on opposite ends of the columnar rods. The arc-shaped sliding plates are slidably installed on the inner walls of the four columnar rods. The arc-shaped grooves are formed on the inner walls of the arc-shaped sliding plates. The springs are disposed between the columnar rods and the arc-shaped sliding plates. There are several rotating shafts, which are fixedly installed on the inner walls of the arc-shaped grooves at equal intervals. The rollers are rotatably installed on the outer walls of the several rotating shafts.

[0011] Preferably, the cylindrical rods are arranged vertically, and the two cylindrical rods are in contact with each other, and the outer wall of the roller is in contact with the outer wall of the front drive shaft.

[0012] By employing the above technical solution, this utility model provides a splash protection device for the drive shaft of a mining vehicle. It possesses at least the following beneficial effects:

[0013] (1) By setting sealing strip one and sealing strip two, this utility model can ensure the sealing of the protective plate, preventing the mud from being carried to the surface of the protective plate installed on the top beam when the mining vehicle is moving, so that it can flow to the front drive shaft. The self-locking can be released by lifting the plate with one hand, eliminating the need for tools such as wrenches and screwdrivers, and significantly improving the maintenance efficiency of the front drive shaft.

[0014] (2) The present invention provides a buffer for the driving stress of the arc-shaped slide plate that moves up and down in a small range by setting the spring, which effectively disperses the abnormal stress and reduces the risk of fatigue fracture of the front drive shaft. At the same time, the zero-resistance rolling design of the roller ensures the free operation of the front drive shaft and completely avoids the friction loss caused by rigid limit.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] A splash protection device for the drive shaft of a mining vehicle, such as Figures 1-4As shown, the front driveshaft 1 is installed on the front drive axle assembly and the output end of the power transmission of the vehicle. A top beam mounting protective plate 11 is provided on the outer wall of the front driveshaft 1. A shaft 12 is fixedly installed on the inner wall of the bearing end of the top beam mounting protective plate 11. A bottom mounting protective plate 13 is rotatably installed on the outer wall of the shaft 12. A quick-release device 2 is provided on the outer walls of the top beam mounting protective plate 11 and the bottom mounting protective plate 13. The quick-release device 2 includes an outer shaft block 21, which is fixedly installed on the outer wall of the bottom mounting protective plate 13. A fixing rod 22 is fixedly installed on the inner wall of the outer shaft block 21. A clamping plate 23 is rotatably installed on the outer wall of the fixing rod 22. A clamping block 24 is fixedly installed on the outer wall of the top beam mounting protective plate 11.

[0024] A sealing strip 1101 is fixedly installed on the bottom surface of the top beam protective plate 11, and a sealing strip 2 1301 is fixedly installed on the side of the bottom protective plate 13 near the sealing strip 1101.

[0025] The card plate 23 is L-shaped, and the top of the card plate 23 is an inverted triangle. The card plate 23 is elastic. The top of the card block 24 is a right triangle, and the inverted triangle at the top of the card plate 23 is located on the movement trajectory of the right triangle at the top of the card block 24.

[0026] This utility model discloses a protective device for the drive shaft of a mining vehicle to prevent splashing. Existing protective covers for the drive shaft of mining vehicles are installed and fixed with screws, requiring individual screw removal for maintenance. This is inconvenient, time-consuming, and labor-intensive. Therefore, after screwing the top beam protective plate 11 onto the inner wall of the vehicle, the bottom protective plate 13 is rotated to join the top beam protective plate 11. Sealing strips 1101 and 1301 are then fitted together for sealing. The elastic locking plate 23 is then pushed inward. The inverted triangular slope at the top of the locking plate 23 first contacts the right-angled triangular slope at the top of the locking block 24. The elastic locking plate 23 then stretches and deforms to secure the device. The bottom protective plate 13 is quickly installed and fixed by inserting the right-angled triangle at the top of the locking block 24. When maintenance of the front drive shaft 1 is required, the inverted triangle of the locking plate 23 is gently pulled upwards, causing the inverted triangle of the locking plate 23 to disengage from the right-angled triangle at the top of the locking block 24, thus releasing the bottom protective plate 13 from the top beam protective plate 11. The sealing strips 1101 and 1301 ensure the sealing of the protective plate, preventing the slurry from being carried to the surface of the top beam protective plate 11 when the mining vehicle is moving, and thus flowing to the front drive shaft 1. The self-locking can be released by gently lifting the locking plate 23 with one hand, eliminating the need for tools such as wrenches and screwdrivers, and significantly improving the maintenance efficiency of the front drive shaft 1. Example

[0027] This embodiment, based on embodiment 1, specifically includes the following:

[0028] like Figure 5 As shown, the inner walls of the top beam mounting protective plate 11 and the bottom mounting protective plate 13 are provided with a buffer device 3. The buffer device 3 includes a column rod 31, an arc-shaped limiting plate 32, an arc-shaped sliding plate 330, an arc-shaped groove 331, a spring 34, a rotating shaft 35, and a roller 36. There are four column rods 31, and the four column rods 31 are respectively fixedly installed on the inner walls of the top beam mounting protective plate 11 and the bottom mounting protective plate 13. The arc-shaped limiting plate 32 is fixedly installed on one end of the column rods 31. The arc-shaped sliding plate 330 is slidably installed on the inner wall of the four column rods 31. The arc-shaped groove 331 is opened on the inner wall of the arc-shaped sliding plate 330. The spring 34 is set between the column rods 31 and the arc-shaped sliding plate 330. There are several rotating shafts 35, and the several rotating shafts 35 are fixedly installed on the inner wall of the arc-shaped groove 331 evenly and equidistantly. The roller 36 is rotatably installed on the outer wall of the several rotating shafts 35.

[0029] The column rods 31 are arranged vertically, and the two column rods 31 are in contact with each other. The outer wall of the roller 36 is in contact with the outer wall of the front drive shaft 1.

[0030] In the present invention, a protective device for preventing splashing of the drive shaft of a mining vehicle is used. During vehicle operation, stress concentration easily occurs at the connection point of the front drive shaft 1, potentially leading to breakage. Therefore, after the bottom protective plate 13 is closed, the roller 36 contacts the connection point of the front drive shaft 1. The rolling of the roller 36 does not hinder the rotation of the front drive shaft 1. When the mining vehicle is in motion, the front drive shaft 1 shifts vertically due to stress. During this shift, the front drive shaft 1 will press against the roller 36 vertically. The 6 drives the rotating shaft 35 to move up and down slightly. The rotating shaft 35 drives the curved sliding plate 330 to move up and down slightly within the curved groove 331 of the curved sliding plate 330. The curved sliding plate 330 moves up and down slightly within the curved limiting plate 32. The spring 34 provides a buffer for the driving stress of the curved sliding plate 330, which moves up and down slightly, effectively dispersing abnormal stress and reducing the risk of fatigue fracture of the front drive shaft 1. At the same time, the zero-resistance rolling design of the roller 36 ensures that the front drive shaft 1 can rotate freely, completely avoiding frictional loss caused by rigid limiting.
