[0031] figure 1 For the schematic structural diagram of the accelerator linkage mechanism provided by the first embodiment of the present invention, please refer to figure 1 .

[0032] The accelerator linkage mechanism 100 provided in this embodiment includes an operating rod 110, a multi-way valve 120, a position detection unit 130, a first end cover 140, a second end cover 150, a connecting shaft 160, a control unit (not shown in the figure) and engine (not shown). Wherein, the multi-way valve 120 includes a valve body 121 , a main valve core 122 and a flow control valve core 123 . The position detection unit 130 includes a magnetic source element 131 and a magnetic induction element 132 . Specifically, the magnetic induction element 132 may be a Hall sensor.

[0033]Specifically, the valve main body 121 is provided with a through hole, and the main valve core 122 passes through the through hole and can move axially relative to the valve main body 121 . That is to say, ...

[0058] The truck-mounted crane provided in this embodiment includes an oil pump, an oil tank and the accelerator linkage mechanism 100 in the first embodiment. The oil pump communicates with the second shaft hole 1225 on the main valve core 122 and is used to deliver hydraulic oil to the multi-way valve 120 . The oil tank communicates with the sixth passage 1218 on the valve body 121 for recovering the hydraulic oil output by the multi-way valve 120 .

[0059]It should be noted that the truck-mounted crane provided in this embodiment may include multiple operating levers 110 . The functions that can be realized by the operating rod 110 through the multi-way valve 120 can be luffing, turning, or telescopic boom, etc. The movement of the operating rod 110 is in one-to-one correspondence with the position signal sent by the position detection unit 130 to the control unit. That is to say, when the operation lever 110 is operated to control the movement of the truck-mounted crane...

Abstract

The invention provides an accelerator link mechanism and a lorry-mounted crane, and relates to the technical field of engineering machines. The accelerator link mechanism comprises an operating lever, a multi-way valve, an engine, a position detection unit and a control unit. The multi-way valve comprises a valve main body and a main valve element. A through hole is formed in the valve main body, and the main valve element penetrates through the through hole and can move in the axial direction relative to the valve main body. One end of the main valve element is hinged to one end of the operating lever. The position detection unit is arranged at the other end of the main valve element and used for detecting a position signal of the main valve element, converting the position signal into a sensing signal and sending the sensing signal to the control unit. The control unit is used for transmitting a corresponding voltage signal to the engine and controlling the rotating speed of the engine according to the sensing signal. The engine is used for providing hydraulic oil for the multi-way valve. By adoption of the accelerator link mechanism, an operator can achieve link control over the rotating speed of the engine while operating the operating lever, and accordingly the oil supply flow of the engine is controlled.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an accelerator linkage mechanism and a truck-mounted crane. Background technique [0002] At present, the ground operation model of the truck-mounted crane occupies a mainstream position in the truck-mounted crane. The operation mode of this type of truck-mounted crane is that the operator stands on the ground, operates the crane with both hands, and at the same time controls the engine throttle to realize the speed control. Since the operator has to operate the crane and control the accelerator, the operation is very inconvenient. Especially when carrying out a plurality of crane movement operations simultaneously, can't control accurately and effectively especially. In addition, because the matching between the throttle and the crane action is dependent on human control, each operator has different cognitive levels and habits, resulting in very inconsistent degr...
