Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] Combine below figure 1 , the preferred embodiment of the present invention is described in further detail, the vehicle of the preferred embodiment: comprises a chassis and a cargo box, the cargo box is connected with the chassis, and a tarpaulin mechanism 9 for covering the cargo box is installed on the cargo box. The tarpaulin mechanism 9 is a mechanism for driving the tarpaulin to cover and open. The tarpaulin is used to prevent the muck truck from raising dust and leaking along the way, causing secondary pollution and damage to the urban environment.

[0019] A lifting oil cylinder 11 is arranged between the container and the chassis. The cargo box is hinged with the chassis, and the...

Abstract

The invention discloses a vehicle. The vehicle comprises a chassis and a packing case. The packing case is hinged to the chassis. An awning mechanism for shielding the packing box is installed on the packing case. The vehicle comprises an awning mechanism hydraulic oil path, a hydraulic pump, a first reversing valve and a hydraulic motor are arranged in the awning mechanism hydraulic oil path, the first reversing valve is arranged in an oil path between the hydraulic pump and the hydraulic motor, and the hydraulic motor is connected with the awning mechanism. According to the vehicle, the hydraulic motor drives the awning mechanism to be closed and opened, due to the high power of the hydraulic motor, larger traction force is achieved through large torque of the hydraulic motor, and the hydraulic motor drives the awning mechanism to achieve soil scraping and leveling functions. A pressure sensor is arranged in the hydraulic oil path of the awning mechanism, the running resistance of the awning mechanism is automatically recognized, the vehicle automatically retreats after encountering a large obstacle, and the running awning mechanism is protected.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a vehicle. Background technique [0002] At present, when transporting urban muck trucks and dump trucks, the containers are generally covered with tarpaulins. The tarpaulins are used to prevent the muck trucks from raising dust and leaking along the way, causing secondary pollution and damage to the urban environment. [0003] Now the tarpaulins all adopt the motor-driven tarpaulin mechanism to realize the covering and opening of the tarpaulin. Due to the limitation of the power of the motor, it is often stuck, easy to burn the insurance, does not have protection functions such as automatic retreat, and has many faults. Contents of the invention [0004] In view of this, the present invention proposes a vehicle to solve the problem of driving the tarpaulin mechanism. [0005] On the one hand, the present invention provides a kind of vehicle, comprises chassis and cargo box, and cargo ...
