Therefore, the technical scheme of the invention is as follows:
a double-power crane engine operation safety protection device comprises a first oil delivery pipe, a three-way electromagnetic valve, a second oil delivery pipe and a third oil delivery pipe; the three-way electromagnetic valve is provided with an inlet end, a first outlet end and a second outlet end, wherein the first outlet end is communicated with the inlet end under the power-off state of the electromagnetic valve and is closed between the inlet end and the power-on state of the electromagnetic valve, and the second outlet end is closed between the inlet end and the power-off state of the electromagnetic valve and is communicated with the inlet end under the power-on state of the electromagnetic valve; one end of the first oil pipeline is connected and communicated with the outlet end of the oil way control device, and the other end of the first oil pipeline is connected and communicated with the inlet end of the three-way electromagnetic valve; one end of the second oil delivery pipe is connected and communicated with a first outlet end of the three-way electromagnetic valve, and the other end of the second oil delivery pipe is connected and communicated with a joint end additionally arranged on the oil tank; one end of the third oil pipeline is connected and communicated with the second outlet end of the three-way electromagnetic valve, and the other end of the third oil pipeline is connected and communicated with an oil way interface end of an operating rod in the cab; the three-way electromagnetic valve is connected with a vehicle-mounted power supply or an external power supply through a power line, and a control switch is arranged on the power line.
Preferably, the control switch is installed in the cab.
Compared with the prior art, the double-power crane engine operation safety protection device is reasonable in structural design and simple to operate, the operation safety protection device is additionally arranged in the engine chamber of the crane, the control switch is installed in the cab, the dangerous accidents caused by mistaken touch of the operating rod are effectively avoided by closing the control switch in the running process of the crane, the normal working state of the operating rod is recovered through manual operation when operation is needed, and the safety operation is effectively guaranteed.
Drawings
FIG. 1 is a schematic structural diagram of a dual-power crane engine operation safety protection device of the present invention.
Detailed Description
The invention will be further described with reference to the following figures and specific examples, which are not intended to limit the invention in any way.
As shown in fig. 1, the dual-power crane engine operation safety protection device is installed in an engine system, specifically in an engine room, and specifically comprises a first oil delivery pipe 1, a three-way electromagnetic valve, a second oil delivery pipe 2 and a third oil delivery pipe 3; wherein the content of the first and second substances,
the first oil delivery pipe 1, the second oil delivery pipe 2 and the third oil delivery pipe 3 are all pipelines which are the same as the oil delivery pipes originally connected between the outlet end of the oil way control device and the oil way interface end of the operating rod in the cab in the engine chamber of the crane and are directly purchased from commercial products; the three-way electromagnetic valve is purchased from a commercial product, and is provided with an inlet end and two outlet ends, and is particularly divided into a first outlet end and a second outlet end, wherein the inlet end and the first outlet end are in a normally open state, namely when the coil of the electromagnetic valve is powered off, the inlet end and the first outlet end are in a communicated state, and the inlet end and the second outlet end are in a closed state; when the electromagnetic valve coil is electrified, the inlet end and the first outlet end are in a closed state, and the inlet end and the second outlet end are in a communicated state;
one end of the first oil pipeline 1 is connected and communicated with the outlet end of the oil way control device, and the other end of the first oil pipeline is connected and communicated with the inlet end of the three-way electromagnetic valve;
one end of the second oil pipeline 2 is connected and communicated with a first outlet end of the three-way electromagnetic valve, and the other end of the second oil pipeline is connected and communicated with a joint end additionally arranged on the oil tank, so that the oil entering the first oil pipeline 1 can return to the oil tank through the second oil pipeline 2;
one end of the third oil delivery pipe 3 is connected and communicated with the second outlet end of the three-way electromagnetic valve, and the other end of the third oil delivery pipe is connected and communicated with an oil way interface end of an operating rod in the cab, so that a crane driver can carry out hoisting operation in the cab by controlling the operating rod;
the three-way electromagnetic valve is connected with a vehicle-mounted power supply or an external power supply through a power line, and a control switch is arranged on the power line; the control switch is installed in the cab, so that a crane driver can directly press the control switch to electrify the three-way electromagnetic valve 2 when needing to carry out hoisting operation, and the communication between the operating rod and the oil way control system is realized.
When the engine of the double-power crane works, in the process that a driver drives the crane to travel to a specified position, the first oil delivery pipe 1 is communicated with the second oil delivery pipe 2 because the electromagnetic valve is in a power-off state, so that the operating rod is not communicated with the oil way control system, and the lifting operating rod cannot be touched by mistake in the driving process; and when the hoisting operation is needed, a driver presses the control switch to electrify the electromagnetic valve, at the moment, the first oil delivery pipe 1 is communicated with the third oil delivery pipe 3, and the crane driver can hoist through the control operation rod in a cab.
