Description

Technical Field

[0002] In existing technologies, tractors and harvesters are required for both sowing and harvesting in agricultural production. Both tractors and harvesters are agricultural engineering vehicles. However, due to their large size and the fact that they operate in soft soil, traditional wheeled engineering vehicles are gradually being replaced by tracked engineering vehicles. Tracked engineering vehicles have gained widespread adoption in agriculture due to their advantages of greater load capacity, less susceptibility to soil entrapment, and more stable operation. In existing tracked engineering vehicles, the track structure is mounted on both sides of the vehicle via a main axle, which is then mounted on the chassis via a clamping structure. However, this device has the following drawbacks: when in use, the existing main axle clamping structure is usually a fixed structure welded to the chassis, which makes it inconvenient to adjust and maintain the main axle.

[0019] 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.

[0020] Please see Figure 1-4 The present invention provides the following technical solution: a lifting-type engineering vehicle main shaft clamping structure, including: a mounting seat 1. The mounting seat 1 in this technical solution is conventional technology in the field and has no relation to the technical problem in this technical solution. Therefore, it will not be described in detail in this technical solution. In specific use, after the mounting seat 1 is placed on the ground, the lower limit ring 7 and the upper limit ring 9, which are threaded together by the bidirectional lead screw 4, are used to clamp and fix the lifting-type engineering vehicle main shaft.

[0021] Mounting base 1 is connected to mounting plate 2 on its side wall. Mounting plate 2 is connected to motor 3 on one side. The transmission end of motor 3 is threaded to bidirectional lead screw 4. Bearings 5 ​​are sleeved at both ends of bidirectional lead screw 4. Moving block 6 is threaded to the surface of bidirectional lead screw 4. The top of moving block 6 is fitted with lower limit ring 7, and a fixing bolt is horizontally connected through the intersection of the two. One side of lower limit ring 7 is rotatably connected to upper limit ring 9 by first rotating shaft 8. The other side of upper limit ring 9 is threaded to the other side of the top of lower limit ring 7 by screw 10. The horizontal end of mounting base 1 is rotatably connected to support foot 12 by second rotating shaft 11. The side wall of support foot 12 is threaded to mounting base 1 by bolt 13.

[0022] Preferably, the motor 3, the bidirectional lead screw 4, the bearing 5 and the moving block 6 form a threaded connection structure, and the two sets of moving blocks 6 are respectively threaded to both sides of the bidirectional lead screw 4.

[0023] In actual use, the motor 3 starts to rotate, thereby driving the bidirectional lead screw 4 to rotate on the bearing 5, so that the moving blocks 6 connected by threads on both sides of the bidirectional lead screw 4 move simultaneously to the sides or the center point.

[0024] Preferably, the bottom of the lower limit ring 7 is provided with a rectangular protrusion with a threaded groove, the shape and size of which match the top groove and fixing bolt of the moving block 6.

[0025] In practical use, the groove on the top of the movable block 6 facilitates the fitting of the lower limit ring 7, and the connection between the two is fixed by a fixing bolt.

[0026] Preferably, the lower limit ring 7, the first rotating shaft 8, the upper limit ring 9 and the screw 10 form a rotary connection structure, and the inner walls of the lower limit ring 7 and the upper limit ring 9 are provided with triangular serrations at equal intervals.

[0027] In practical use, the lower limit ring 7 and the upper limit ring 9 are used to clamp the main shaft of the vehicle. The triangular serrations on their inner walls facilitate a more stable clamping, while the screw 10 is used to fix the connection between the lower limit ring 7 and the upper limit ring 9.

[0028] Preferably, the mounting base 1, the second rotating shaft 11, and the support foot 12 form a rotating connection structure.

[0029] In practical use, the second rotating shaft 11 connected to one side of the support foot 12 is used to rotate the support foot 12 downward and insert it into the ground. Then, the bolts 13 are used to fix it in the threaded grooves on the front and rear sides of the mounting base 1 to fix its position.

[0030] Preferably, the mounting base 1 has two sets of threaded grooves on both sides of its horizontal end, the shape and size of which are consistent with the bolt 13, and the two sets of threaded grooves on both sides of the mounting base 1 are distributed in an "L" shape.

[0031] In practical use, the threaded grooves on the front and rear sides of the mounting base 1 facilitate the fixing of the position of the support foot 12 during storage and support.

[0032] Working principle: When lifting engineering vehicles, after the mounting base 1 is placed on the ground, the motor 3 installed on one side of it is started to rotate, thereby driving the double-acting screw 4 to rotate on the bearing 5. This causes the moving blocks 6 connected to the threads on both sides of the double-acting screw 4 to move to the sides or center point at the same time, thereby driving the lower limit ring 7 above the moving blocks 6 to move to both ends of the main shaft of the engineering vehicle. Then, the upper limit ring 9 connected to one side of the lower limit ring 7 is opened on (8) and abuts against the main shaft of the vehicle. Then, the screw 10 passes through the upper limit ring 9 and is fixed to the lower limit ring 7 at the bottom, thereby fixing the position of both. At the same time, according to the position of the mounting base 1, the bolts 13 fixed on the support feet 12 on the front and rear sides of the mounting base 1 are loosened and removed. Then, the second rotating shaft 11 connected to one side of the support feet 12 is used to rotate the support feet 12 downward and insert them into the ground. Then, the bolts 13 are fixed in the threaded grooves on the front and rear sides of the mounting base 1 to fix its position.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
