Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0037] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0038] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses a dump truck lifting device and a dump truck. The dump truck lifting device includes a limit control module, a lift control module and a lift module; the limit control module and the lift control module are connected to the lift module through a wire harness; wherein the limit control module The lifting module is used to send a limit electrical signal to the lift module; the lift control module is used to send a lift control electrical signal to the lift module; the lift module is used to The signal and the lift control electrical signal control the lift angle of the carriage. Among them, due to the electrical connection between the limit control module and the lift module through the wiring harness, the lift angle control and limit control of the carriage are realized, which avoids the need to use the air pipe connection to cause assembly when the limit control is realized through the air control valve. The difficult problem improves the convenience of later modification and maintenance.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a dump truck lifting device and a dump truck. Background technique [0002] The dump truck is a special vehicle that uses the power of the engine to drive the hydraulic lifting mechanism, tilts the carriage at a certain angle to unload, and relies on the weight of the carriage to reset it. If the lifting angle is too small, the goods in the compartment cannot be dumped, and if the lifting angle is too large, the whole vehicle may overturn when tilting the goods. Therefore, it is necessary to control the angle of the carriage at a fixed value to meet normal use and safety performance. [0003] Now most of the car lifting devices limit the position by fixing an air control valve on the hydraulic cylinder. The valve of the air control valve is set in the middle of the ascending air pipe. When the hydraulic cylinder is lifted to a certain angle, the hydraulic cylinder ...
