[0001] The utility model relates to the technical field of semi-trailers, in particular to a cylinder lifting device for a side-dumping semi-trailer and a semi-trailer. Background Art

[0002] The existing lifting device of the side-unloading semi-trailer is composed of hydraulic parts such as a cylinder and a fuel tank. This device has many structural requirements, such as: the need to increase the welding of oil circuit joints and oil circuit steel pipes, the pressing of oil pipe hoses, the main engine modification for the power take-off between the tractor and the trailer, and the need to match many types of power take-offs according to different tractors, etc. The overall oil circuit device is relatively complicated to manufacture and modify, and the cost of hydraulic parts is relatively high.

[0003] However, the side-unloading semi-trailer has a long body and more positions for installing lifting devices. The power requirements of the lifting devices can be reduced by increasing the number of lifting devices. In addition, since the lifting height requirement of the side-unloading semi-trailer is lower than that of the traditional dump truck, the demand for power devices is further weakened.

[0004] Based on the above reasons, a series of problems brought about by the transmission mode of the traditional hydraulic cylinder can actually be solved by changing the power mode. Based on the above technical requirements, technical personnel in this field need to find a technical solution to simplify the device, which can both reduce costs and ensure feasibility.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0025] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0026] Example 1

[0027] like Figure 1-Figure 3 As shown, a cylinder lifting device for a side-unloading semi-trailer comprises a cylinder 1, a cylinder fixing beam 2, a cylinder fixing seat 3 and a lifting cylinder head 4.

[0028] The cylinder fixed cross beam 2 includes two cross beams parallel to each other, the two ends of the two cross beams are used to connect with the frame of the semi-trailer, the cross beam is an I-beam, the notch of the I-beam is arranged outward, and the inner wall of the I-beam is provided with a hollow weight-reducing hole. In this embodiment, the two cross beams are used to connect between the lower longitudinal beams of the frame.

[0029] The two ends of the cylinder fixing seat 3 are respectively fixed on the two cross beams so that the cylinder fixing seat 3 is located between the two cross beams as a whole. Specifically, in the present embodiment, the cylinder fixing seat 3 includes a seat body 31, a bolt 32, a through hole 33, a rib plate 34 and a reinforcing ring 35. The main part of the bolt 32 is welded to the seat body 31, the rib plate 34 is welded to the seat body 31 and has a hole opposite to the bolt 32 for locking the bolt 32. The through hole 33 is opened at the center of the seat body 31, and the reinforcing ring 35 is arranged around the through hole 33. The cylinder body part of the cylinder 1 is fixed to the cylinder fixing seat 3, and can be fixed to the cylinder fixing seat 3 by bolts or welding. The telescopic rod of the cylinder passes through the through hole 33, and the lifting cylinder head 4 is installed on the top of the telescopic rod of the cylinder 1.

[0030] The inner wall of the I-beam is provided with a mounting hole, and the end of the bolt 32 of the cylinder fixing seat 3 is inserted into the mounting hole and locked by a nut. In a preferred embodiment, the two ends of the cylinder fixing seat 3 are welded and fixed to the bottom edge or inner side edge of the I-beam.

[0031] Air cylinders are used to replace traditional oil cylinders. The overall supporting structure of air cylinders is simpler than that of oil cylinders, and the semi-trailer itself has its own air source, so the complexity is greatly reduced.

[0032] Example 2

[0033] like Figure 4 As shown, a semitrailer comprises a frame 5, a car body 6 and a cylinder lifting device 7 for a side-unloading semitrailer, wherein the frame 5 has a lower frame longitudinal beam, the two ends of the cylinder fixed cross beam 2 are fixed between two adjacent lower frame longitudinal beams, the top head 4 of the lifting cylinder is hinged with the pin shaft of the top seat fixing seat of the side-unloading upper frame cylinder at the bottom of the car body 6, the cylinder is connected to the lower frame air storage cylinder through an air pipe and the on-off control of a manual rotary valve is used to realize the lifting of the cylinder, and the number of the cylinder lifting devices for the side-unloading semitrailer is at least two, which are distributed along the length direction of the frame.

[0034] With this structural transformation, the traditional semi-trailer can use its own air source as the driving force, and use the cylinder to lift the entire car body, which reduces the production cost of the whole vehicle, reduces the difficulty of production, and improves work efficiency.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
