Problems solved by technology

The problem with traditional dump trucks is that, in order to facilitate the control of the dump truck joystick, the position of the joystick is generally close to the driver, and the position is low.
In this case, the control lever is easily touched by the driver or people around the dump truck, causing the dump truck compartment to collapse suddenly. If there are people under or near the compartment performing chassis maintenance, it may cause a safety accident
In order to ensure that the carriage does not fall suddenly, existing dump trucks generally adopt the form of carriage struts. During operation, it is necessary to operate the control lever and carriage strut. Multiple adjustments, the whole process is rather cumbersome. At the same time, this structure can only control the descent of the carriage, and cannot safely control the carriage at any angle

Embodiment Construction

[0021] figure 1 It is a structural schematic diagram of the present invention; figure 2 It is a partial enlarged view of the limit mechanism; image 3 is a schematic diagram of the structure of the limiting part as a limiting pin; Figure 4 is a structural schematic diagram in which the limiting part is a limiting block.

[0022] As shown in the figure: the safety protection device for manipulating the dump car in this embodiment includes a car lift control lever 1 and a limit mechanism 2 that cooperates with the control lever 1 to limit the lift of the car. The limit mechanism 2 includes It is used for the guide part and the limiting part of the control lever; the control lever 1 controls the power machine through the control cable (or pull rod), and the oil circuit control structure is installed inside the power machine. The position-limiting mechanism 2 is equivalent to a safety lock, and the position of the compartment is ensured by the safety lock to increase safety. ...

Abstract

The invention discloses a safety protection device for controlling a self-discharging vehicle carriage. The safety protection device comprises a carriage lifting control rod and a limiting mechanism matched with the control rod to limit the control rod in controlling carriage descending. The limiting mechanism is provided with a limiting part for controlling the control rod. Based on a self-discharging vehicle power part, to guarantee carriage lifting safety, an oil line hydraulic oil flow control structure is installed on an oil line generally; by limiting the power machine control rod, the oil line control structure can well serve the effect of preventing hydraulic oil from flowing, abrupt change of the carriage position is avoided, and use safety of a whole vehicle is enhanced; when the carriage is lifted or descended, operation on the control rod can be facilitated, the carriage can be lifted or descended according to the operation requirements, operation procedures and labor intensity of operators are reduced, and the safety protection device is flexible and convenient to operate and can perform safety protection on the carriage which is at a random overturning angle.

Description

technical field [0001] The invention relates to the field of dump trucks, in particular to a safety protection device for manipulating a dump truck and a dump truck and the dump truck. Background technique [0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. It is composed of a motor vehicle chassis, a hydraulic lifting mechanism, and a carriage. It saves unloading time and labor, shortens the transportation cycle, improves production efficiency, reduces transportation costs, and indicates the loading volume. It is a commonly used transportation machinery. The problem with traditional dump trucks is that, in order to facilitate the operation of the dump truck joystick, the position of the joystick is generally close to the driver and the position is low. In this case, the control lever is easily touched by the driver or people around the dump truck, causing the dump truck compartment to suddenly...
