Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobiles, in particular to a self-dumping truck with double top rear dumping and side dumping. BACKGROUND

[0002] The self-dumping truck is a special vehicle that uses the engine power to drive the hydraulic lifting mechanism to tilt the vehicle compartment to a certain angle to unload the goods, and relies on the self-weight of the vehicle compartment to reset.

[0003] The conventional self-dumping truck currently adopts the rear dumping structure, but the front end of the cargo box will be sharply increased in height when the rear dumping structure is used (the height of the front portal is generally increased by 1442mm after the cargo box is turned over by 45°), which cannot be lifted in the basement or other low environments. The cargo box height changes less after the cargo box is lifted by side dumping, which is suitable for the basement and side dumping scenarios (the height of the front portal is higher than the cab by 175mm after the cargo box is turned over by 45°, and a lower portal frame can be used to ensure that the cargo box is turned over without exceeding the height of the cab), but the overall risk of side dumping is greatly increased, the lifting road surface needs to be flat and without angle, and the left and right turning hinges need to be adjusted to determine whether the left side or the right side is turned over. Both of the two turning forms have certain limitations and advantages. The present application designs a single cylinder self-dumping truck with rear dumping and side dumping functions by using a gas cylinder and an electric cylinder. The rear dumping is used in open areas to improve the lifting efficiency, the side dumping is used in basements to avoid manual unloading, the left side and right side of the side dumping are turned over without manual operation by using the gas cylinder and the electric cylinder, the lifting efficiency is improved, the personnel is avoided to get off the vehicle to adjust, and the applicability and practicality of the vehicle are greatly improved.

DETAILED DESCRIPTION

[0037] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of the components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0038] As Figure 1A , Figure 1B and Figure 2As shown, the self-unloading truck of the present application still uses a set of lifting hydraulic system, but the hydraulic cylinder 2 is changed from two supports to four supports, and the hydraulic cylinder 2 has separate inlet and outlet ports, instead of increasing the oil port at one side support in the traditional design. The traditional design has a thicker support due to the reserved oil port, and has higher weight and cost. The oil port of the hydraulic cylinder is designed separately in the present application, and the four supports are relatively thin, so that the weight and cost change little. In order to meet the rollover, the structure of the top of the hydraulic cylinder is a movable ball pin 10, which allows the pin shaft support hole to deflect to the left and right sides by a certain angle. When the rear is turned over, there is no deflection angle, and when the side is turned over, it can be deflected.

[0039] As shown, Figures 3A-9B , the hydraulic cylinder 2 is vertically placed under the action of gravity for resetting and has two sets of support systems - the rear rollover support on the left and right sides and the side rollover support on the front and rear sides (i.e. 4 hydraulic cylinder supports 3). The two sides have tracks (support tracks 5) and limiting devices (not shown) to ensure normal movement while limiting the travel of the hydraulic cylinder support 3 from the base, while always ensuring that at least one set of support system is working. The pneumatic cargo electric cylinder 4 pushes the center of mass of the turnover support to ensure that there is no jamming during the pushing process, and if necessary, increase the lubricating grease in the running track, and the support on the side of the inlet and outlet hydraulic cylinder has a chamfer (not shown) to facilitate the inlet and outlet of the hydraulic cylinder.

[0040] At the same time, a guide channel is arranged on the right side of the lower right side of the hydraulic cylinder support, and a guide channel is arranged on the left side of the lower left side of the hydraulic cylinder support, which is composed of wear-resistant nylon material, and is used to ensure that the lower side of the hydraulic cylinder rotates to the right when the cargo box is turned to the left, and the lower side of the hydraulic cylinder rotates to the left when the cargo box is turned to the right, so that the hydraulic cylinder does not sway forward and backward, and the risk of deflection of the hydraulic cylinder during single-cylinder lifting is eliminated.

[0041] In order to meet the rollover and rear rollover at the same time, there is a gap between the turnover support and the turnover plate to ensure that the tail of the cargo box is turned over when the cargo box is turned over, and the turnover plate does not interfere with the side turnover support when the cargo box is turned over.

[0042] The double-top rear rollover with side rollover self-unloading truck of the present application is used as follows:

[0043] The double-top rear rollover with side rollover self-unloading truck is in a non-use state as shown in Figures 3A-4B , the left and right shafts 21 are connected with the shaft holes 31, and the front and rear shafts 21 are connected with the shaft holes 31.

[0044] When the rear is turned over (as shown in Figure 5A , Figure 5B , Figure 8When the side tipping is needed (as shown in Figure 7 , ,

[0045] , Figure 6A , Figure 6B , Figure 9A and Figure 9B ), the left and right rear tipping supports move left and right, and are not in contact with the hydraulic cylinders (the left and right rotating shafts 21 are disconnected from the rotating shaft holes 31), and also ensure no interference when lifting, and the front and rear side tipping supports are in place (the front and rear rotating shafts 21 are connected to the rotating shaft holes 31); the tail box rear tipping support 9 is in an inactive state, and according to the needs, the left and right side tipping supports and the upper pin shafts of the hydraulic cylinders on the same side are in a working state on one side and in an inactive state on the other side, and cannot be in a working state at the same time: when the left side tipping is needed, the lifting control system controls the hydraulic oil to input hydraulic oil to the right hydraulic cylinder, the left hydraulic cylinder is not supplied with oil, and the left hydraulic cylinder upper pin shaft is in an inactive state and does not move with the hydraulic cylinder; when the right side tipping is needed, the lifting control system controls the hydraulic oil to input hydraulic oil to the left hydraulic cylinder, the right hydraulic cylinder is not supplied with oil, and the right hydraulic cylinder upper pin shaft is in an inactive state and does not move with the hydraulic cylinder, which ensures that the center of gravity does not deviate excessively when the box is tipped, thereby reducing the risk of vehicle tipping.

[0046] Although the present application has been disclosed with the above-mentioned embodiments, it is not intended to limit the present application, and any person skilled in the art can make various selections and modifications without departing from the spirit and scope of the present application, and therefore the protection scope of the present application is defined by the claims and their equivalent forms.
