Description

Technical Field

[0001] This utility model relates to a tanker transport vehicle. Background Technology

[0002] A prior art tanker truck includes a truck chassis and a powder / granular material transport tank mounted on the truck chassis. The truck chassis includes a frame with longitudinal beams. Correspondingly, a subframe is fixed to the bottom of the powder / granular material transport tank. Shock-absorbing pads are installed between the subframe and the longitudinal beams. The front of the frame has a power take-off (PTO) connected to a gearbox and an air compressor fixed to the outside of the longitudinal beams. The PTO is connected to a main drive shaft, and the air compressor has an input shaft.

[0003] Although the tanker trucks described above have shock-absorbing pads installed between the subframe and longitudinal beams, the shock absorption effect is poor. Furthermore, due to the structural characteristics and size constraints of the air compressor, it can only be installed on the outside of the longitudinal beams, and the main drive shaft and the air compressor's input shaft are not aligned. This causes vibration when the main drive shaft is running, making the power take-off, main drive shaft, and air compressor susceptible to damage. Moreover, in the event of a traffic accident, rollover is inevitable for tanker trucks. The lack of necessary protective measures for the top and sides of the tank means that the damage to the tank is quite severe when the vehicle overturns. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and propose a tanker truck with good shock absorption effect, and when the main drive shaft is running and the air compressor is working, the main drive shaft runs smoothly and the power take-off, main drive shaft and air compressor are not easily damaged.

[0005] To solve the above-mentioned technical problems, this utility model provides a tanker transport vehicle, including a truck chassis and a powder / granular material transport tank mounted on the truck chassis. The truck chassis includes a frame with longitudinal beams, and a sub-frame is fixed to the bottom of the powder / granular material transport tank. Shock-absorbing pads are installed between the sub-frame and the longitudinal beams. The front of the frame has a power take-off (PTO) connected to a gearbox and an air compressor fixed to the outside of the longitudinal beams. The PTO is connected to a main drive shaft, and the air compressor has an input shaft. The vehicle is characterized in that a transmission support is fixed to the inner side of the front longitudinal beams of the frame, and a subordinate drive shaft is rotatably mounted on the transmission support. A drive pulley is fixedly mounted on the main drive shaft, which is parallel to the input shaft and located in the same horizontal plane. The other end of the main drive shaft is connected to the drive pulley, and the main drive shaft and the drive pulley are on the same straight line. An input pulley is also fixedly mounted on the input shaft, and a drive belt connects the drive pulley to the input pulley of the air compressor. An upper connecting lug with an L-shaped cross-section is fixedly connected to the outer side of the subframe, and a lower connecting lug with an inverted L-shaped cross-section is fixedly connected to the outer side of the longitudinal beam. The upper and lower connecting lugs are connected by connecting bolts, and a shock-absorbing spring is mounted on the connecting bolt located above the upper connecting lug.

[0006] The tanker truck with the above structure has better shock absorption due to the addition of shock-absorbing springs, which have greater elasticity and can provide better cushioning. Since the main drive shaft and the slave drive shaft are on the same straight line, and the slave drive shaft is parallel to the input shaft and located in the same horizontal plane, the direct connection between the main drive shaft and the input shaft is changed. Therefore, the main drive shaft will not vibrate during operation and runs smoothly. The rotation is transmitted to the air compressor through the transmission pulley, and the air compressor can work normally. When the main drive shaft is running, the power take-off, the main drive shaft, and the air compressor are not easily damaged.

[0007] As an improvement of this utility model, the top of the powder material transport tank is provided with a tank top protection device and the side is provided with a tank side wall protection device. The tank top protection device consists of side steel plates fixed on the left and right sides of the top of the tank and end steel plates fixed on the front and rear ends of the top of the tank. The bottom of the end steel plates forms an arc-shaped surface corresponding to the outline of the top of the tank. The ends of the left and right side steel plates are welded to the end steel plates at the front and rear ends. The tank side wall protection device consists of reinforcing rings that are symmetrically welded at intervals to the outer side of the bottom of the left and right side steel plates, and the shape corresponds to the outer outline of the tank. The reinforcing rings are welded to the outer wall of the tank.

[0008] Furthermore, the bottom ends of the two reinforcing rings have an opening or are connected as one piece.

[0009] Furthermore, the side steel plate is corrugated in shape.

[0010] As a further improvement of this utility model, the top of the side steel plate is bent inward to form a groove-shaped reinforcing part, and the bottom of the side steel plate is bent inward to form an angle-shaped connecting part corresponding to the top contour of the tank.

[0011] Furthermore, the reinforcing ring is a basin-shaped component with a "basin-shaped" cross-section.

[0012] The powder and granular material transport tank is equipped with a top protection device and a side wall protection device, which achieves the following beneficial technical effects: 1. When the vehicle overturns, the top protection device, composed of side steel plates and end steel plates, provides good protection for the top of the tank, while the reinforcing rings on both sides provide good protection for the sides of the tank. 2. Depending on the tank's installation position on the vehicle, the tank portion exposed outside the vehicle can be constructed with the bottom ends of the reinforcing rings connected as one piece, while the tank portion inside the vehicle can be constructed with an opening between the bottom ends of the reinforcing rings, thus reducing production costs. 3. The corrugated shape of the side steel plates enhances their strength. The grooved reinforcing section at the top of the side steel plates further improves their strength, and the angled connecting section at the bottom of the side steel plates enhances their connection strength with the tank. 4. The basin-shaped reinforcing rings further enhance their strength. Attached Figure Description
