Embodiment one

As shown in Figures 1 and 2, a tank car cleaning mechanism is based on the high-pressure water jet mechanism, and its structure includes a three-dimensional rotating nozzle 1, a fixed base 2, a swing mechanism, a telescopic mechanism, a driving mechanism, a guide frame 5, and an arc-shaped nozzle. Wheel pipe 11 and high-pressure water pipe 13; the middle part of a pair of left-right symmetrical guide sleeves 5 is hinged on the fixed base 2, specifically through an anti-ear seat 17 and the fixed base 2 is hinged. A pair of left and right symmetrical arc wheel tubes 11 are respectively arranged in the guide sleeve frame 5 to expand and contract up and down, and two swing mechanisms are arranged on the fixed base 2 to respectively drive a guide sleeve frame 5 to swing; the telescopic mechanism drives the arc wheel tube 11 to The guide frame 5 is stretched up and down; the driving mechanism drives the swing mechanism and the telescopic mechanism to move; the three-dimensional rotating nozzle 1 is installed at the lower end of the arc-shaped wheel tube 11, and the high-pressure water pipe 13 is connected to the three-dimensional rotating nozzle 1 through the upper end of the arc-shaped wheel tube 11 to the lower end.

In order to reduce the lifting height and reduce the requirements for the working environment, the arc-shaped wheel tube 11 includes two sections, the upper and lower sections are hinged, or connected by a hose, and the upper end of the guide sleeve 5 is provided with a supporting arc-shaped The support frame 12 of the wheel tube 11. When the arc-shaped wheel tube 11 goes up, the upper arc-shaped wheel tube 11 falls on the support frame 12, thereby reducing the overall height of the device.

At the same time, in order to ensure smooth expansion and contraction of the arc-shaped wheel tube 11, two sets of radial wheels 14 are provided at both ends of the guide sleeve frame 5 . Specifically, each pair of upper and lower ends contacts the arc-shaped wheel tube 11 from both sides, and there is rolling friction between them, which also plays the role of support.

The swing mechanism includes a cam 3, the cam 3 rotates, and the circumference of the cam 3 contacts with the guide sleeve 5 to drive the guide sleeve 5 to swing. The telescoping mechanism includes a driving gear 9 and a driven gear 15 meshing with each other. The inner arc surface of the arc wheel tube 11 is provided with an arc rack. The hole 16 drives the arc wheel tube 11 to expand and contract up and down.

The drive mechanism includes the drive mechanism of the swing mechanism and the drive mechanism of the telescopic mechanism, which can be independent mechanisms, such as being driven by motors, of course, according to the needs of the structure, the transmission mechanism can be added, such as chain transmission, belt transmission, etc. It is common knowledge technology.

In this example, the driving mechanism of the telescopic mechanism of the driving mechanism includes a motor 7, a driving pulley 8, a driven pulley 19, and a transmission belt 18. The driving pulley 8 is fixed on the motor shaft, and the driven pulley 19 is fixed on the driving gear 9 On the shaft, the motor 7 is fixed on the bracket 6, and the driven pulley 19 is driven by the transmission belt 18 to drive the driving gear 9 to rotate through the driving pulley 8, and the driving gear 9 drives the driven gear 15 with the same diameter to rotate in reverse synchronously, driving the The arc-shaped rack on the inner arc of the shaped wheel tube 11 drives the arc-shaped wheel tube 11 to expand and contract up and down. Drive the three-dimensional rotary nozzle 1 at the lower end to move up and down, and in some structures, it may be necessary to add a transition wheel 10 .

The driving mechanism of the swing mechanism of the driving mechanism includes two sets of chain transmission structures, and a specific set includes a driven sprocket 4, a transmission chain 21, and a driving sprocket 20; the driving sprocket 20 is respectively fixed on the driving gear 9 and the driven gear 15 On the shaft, the driving sprocket 20 is respectively fixed on the shafts of the two cams 3, while the telescopic mechanism moves, while the driving gear 9 and the driven gear 15 rotate, the driving sprocket 20 rotates and drives the driven gear through the transmission chain 21 The sprocket 4 rotates, the cam 3 rotates, and the circumference of the cam 3 contacts the guide frame 5 to drive the guide frame 5 to swing.

This mechanism realizes the three-dimensional rotary nozzle 1 moving up and down and swinging left and right at the same time, making it move three-dimensionally. At the same time, due to the different degree of internal pollution of different storage tanks, the cleaning time of the heavily polluted storage tank is longer, and the motor 7 can be a speed-regulating motor , choose the appropriate cleaning speed, and realize stepless speed regulation, so that different storage tanks can be cleaned.

This mechanism improves the efficiency and quality of tank car cleaning. The arc-shaped wheel tube 11 is foldable, has the characteristics of low overall lifting height, wide working range, simple and reliable structure, and stable operation. It can clean both ends of the tank car at the same time. It is suitable for factories with a height of more than 8m.
