Abstract
The invention discloses an operating mechanism of a hydraulic system of a metering weight bridge test car, which belongs to the technical field of operating mechanisms of hydraulic systems of metering weight bridge test cars. A third operation position is added on the metering weight bridge test car on the basis that an original double-station operation function is not destroyed. The technical scheme includes that a multi-way selector valve is fixedly mounted on one side of an operating platform, a first operating lever is mounted on the multi-way selector valve, a second operating lever is mounted on the other side of the operating platform, the first operating lever is connected with the second operating lever by a connecting rod mechanism, a mounting frame is fixedly mounted on the operating platform, a push-and-pull flexible shaft is fixed to the upper portion of the mounting frame, and a mandrel of the push-and-pull flexible shaft is connected with the first operating lever. The invention is mainly used for operating mechanisms of metering weight bridge test cars.
Description
Technical field
A kind of metering weigh bridge test car of the present invention hydraulic efficiency pressure system operating mechanism belongs to metering weigh bridge test car hydraulic efficiency pressure system operating mechanism technical field.
Background technology
The metering weigh bridge test car is connected to lorry-mounted crane on the car chassis through bolt, is that a kind of metrological service is specifically designed to the special-use vehicle that inspection weighing apparatus tool is carried out periodical survey, and this vehicle integrates lifting and transports, and is easy to use.The metering weigh bridge test car divides two kinds, and a kind of is that lorry-mounted crane is preposition, and a kind of is that lorry-mounted crane is rearmounted.The rearmounted metering weigh bridge test car of lorry-mounted crane has manoeuvring platform, and the operator may stand in and operates lorry-mounted crane on the platform, and its benefit is operator's broad view, can see the particular location of counterweight in the compartment clearly, and is safe and reliable.
The rearmounted metering weigh bridge test car of lorry-mounted crane all has the dual-bit operation function in the market; If operate at the 3rd operating position; Need the multiple directional control valve of former lorry-mounted crane be pulled down, be installed in the 3rd operating station of service platform, realize the control of crane hydraulic system.This structural failure the original dual-bit operation function of crane hydraulic system, make operator's operating position be restricted.Simultaneously, because the position of having changed multiple directional control valve, the original various hydraulic tubings of lorry-mounted crane must bend again, retighten, and have increased transformation of the way cost, have reduced production efficiency.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical matters to be solved provides a kind of original dual-bit operation function of not destroying, and increases the metering weigh bridge test car hydraulic efficiency pressure system operating mechanism of the 3rd bit manipulation position.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of metering weigh bridge test car hydraulic efficiency pressure system operating mechanism; Comprise: first joystick, second joystick, push-and-pull flexible axle, service platform, connecting rod mechanism, multiple directional control valve and erecting frame, multiple directional control valve are fixed on a side of service platform, and first joystick is installed on the multiple directional control valve; Second joystick is installed in the opposite side of service platform, and said first joystick is connected through connecting rod mechanism with second joystick; Erecting frame is fixed on the service platform, and the push-and-pull flexible axle is fixed on the top of erecting frame, and the mandrel of said push-and-pull flexible axle is connected with first joystick.
Be fixed with adapter plate on the said multiple directional control valve, said push-and-pull flexible axle mandrel crust end is stuck on the adapter plate.
The flexible axle of said push-and-pull flexible axle is provided with the flexible axle permanent seat, and said flexible axle permanent seat is fixed on the erecting frame, and the flexible axle fixed seating is in the top of service platform.
The beneficial effect that the present invention is compared with prior art had is: the present invention controls first joystick through the push-and-pull flexible axle; Do not destroy original dual-bit operation function, increase by the 3rd operating position, it is convenient to operate; And the present invention is simple in structure; With low cost, can effectively reduce the repacking cost that measures weigh bridge test car, enhance productivity.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an installing condition reference diagram of the present invention.
Among the figure: 1 is first joystick, and 2 is second joystick, and 3 are the push-and-pull flexible axle, and 4 is service platform, and 5 is connecting rod mechanism, and 6 is multiple directional control valve, and 7 is erecting frame, and 8 is adapter plate, and 9 is the flexible axle permanent seat, and 10 are the metering weigh bridge test car.
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of metering weigh bridge test car hydraulic efficiency pressure system operating mechanism; Comprise: first joystick 1, second joystick 2, push-and-pull flexible axle 3, service platform 4, connecting rod mechanism 5, multiple directional control valve 6 and erecting frame 7, multiple directional control valve 6 is fixed on a side of service platform 4, and first joystick 1 is installed on the multiple directional control valve 6; Second joystick 2 is installed in the opposite side of service platform 4, and said first joystick 1 is connected through connecting rod mechanism 5 with second joystick 2; Erecting frame 7 is fixed on the service platform 4, and push-and-pull flexible axle 3 is fixed on the top of erecting frame 7, and the mandrel of said push-and-pull flexible axle 3 is connected with first joystick 1.
Be fixed with adapter plate 8 on the said multiple directional control valve 6, said push-and-pull flexible axle 3 mandrel crust ends are stuck on the adapter plate 8.
The flexible axle of said push-and-pull flexible axle 3 is provided with flexible axle permanent seat 9, and said flexible axle permanent seat 9 is fixed on the erecting frame 7, and flexible axle permanent seat 9 is positioned at the top of service platform 4.
The push-and-pull flexible axle is a prior art among the present invention.
Working process of the present invention is: service platform 4 of the present invention is installed on the metering weigh bridge test car; Drive first joystick, 1 control multiple directional control valve 6 through control push-and-pull flexible axle 8; Make the staff under the situation that does not change multiple directional control valve 6 positions, increase by the 3rd operating position, it is convenient to operate.
Combine accompanying drawing that embodiments of the invention have been done detailed description above, but the present invention is not limited to the foregoing description, in the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from aim of the present invention, makes various variations.
