[0002] Fracturing trucks are special vehicles used to inject high-pressure, large-volume fracturing fluid into wells to pressurize the formation and squeeze proppant into the cracks. They are mainly used for various fracturing operations in oil, gas and water wells, and can also be used for hydraulic sandblasting, high-pressure hydraulic coal mining in coal mines, and high-pressure hydraulic rust removal on ships. A transmission shaft is set at the bottom of the fracturing truck to drive the vehicle forward.
[0003] In order to protect the drive shaft of the fracturing truck, a guard is provided. However, most of the existing fracturing truck guards are made of thinner metal plates as a whole, with a simple structure and poor protection. Therefore, it is difficult to cope with external impacts. In addition, the bolt connection mechanism is not provided with a sealing mechanism, and mud and stains will adhere to the upper part, which is easy to rust and affect the connection stability of the guard. Therefore, in order to correct the above defects, we propose a fracturing truck drive shaft guard. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0024] Reference Figures 1 to 6 The utility model embodiment provides a fracturing truck transmission shaft guard, which includes an outer protective plate 1: an inner protective plate 2 is fixedly connected to the inner wall of the outer protective plate 1, a plurality of buffer springs 3 are fixedly connected between the inner protective plate 2 and the inner wall of the outer protective plate 1, and a buffer rubber pad 4 is fixedly connected to the inner wall of the inner protective plate 2, a positioning plate 5 is fixedly connected to the two side walls of the outer protective plate 1 and the inner protective plate 2, a pair of cross plates 6 are fixedly connected to the outer protective plate 1, a plurality of bolts 7 pass through the cross plates 6, a plurality of rectangular grooves 8 are opened at the bottom thereof, and a sealing mechanism is provided on the cross plates 6.
[0025] The force is evenly distributed, and a plurality of buffer springs 3 are distributed in a ring shape about the central axis of the outer protective plate 1.
[0026] The force is evenly distributed to improve the installation stability. A pair of transverse plates 6 are symmetrically arranged about the central axis of the outer protective plate 1.
[0027] The bolt 7 can be sealed to prevent the bolt 7 from rusting. The sealing mechanism includes an adjusting block 9 and a sealing cover 10. The adjusting block 9 is located in the rectangular groove 8, and a limiting block 11 passes through the adjusting block 9. The two side walls of the limiting block 11 are fixedly connected to the inner wall of the rectangular groove 8. A telescopic spring 12 is fixedly connected between the adjusting block 9 and the inner wall of the rectangular groove 8. A pair of clamping blocks 13 are fixedly connected to the side wall of the adjusting block 9. The sealing cover 10 is sleeved on the bolt 7, and a clamping groove 14 matching the clamping block 13 is opened on the side wall of the sealing cover 10.
[0028] To increase the friction force, the adjusting block 9 is provided with anti-skid patterns.
[0029] The force is evenly distributed to improve the installation stability of the device. Several pairs of bolts 7 are symmetrically arranged about the central axis of the outer protective plate 1.
[0030] The symmetrical arrangement makes it more beautiful. A pair of positioning plates 5 are symmetrically arranged about the central axis of the outer protective plate 1 .
[0031] Working principle: When the utility model is used, the outer protective plate 1 and the inner protective plate 2 are installed on the chassis of the fracturing vehicle by the bolts 7, and the transmission shaft passes through the opening on the positioning plate 5, and then the adjusting block 9 is pushed, and the telescopic spring 12 is compressed, and then the sealing cover 10 is sleeved on the bolt 7, and the adjusting block 9 is released, and the adjusting block 9 is pushed to move by the telescopic spring 12, and the adjusting block 9 pushes the card block 13 to be inserted into the card slot 14, so as to fix the sealing cover 10 and prevent the bolt 7 from being stained. When the transmission shaft is impacted, the impact force acts on the outer protective plate 1, and is fully buffered by the space between the outer protective plate 1 and the inner protective plate 2. At the same time, the outer protective plate 1 squeezes the buffer spring 3, and the impact force is absorbed by the buffer spring 3, and then the impact force caused by the deformation of the inner protective plate 2 is absorbed by the buffer rubber pad 4, thereby protecting the transmission shaft.
[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
