Abstract
The utility model relates to a power auxiliary driving mechanism for a combustion engine automobile crane. An oil pump outlet connected with a combustion engine through a gear box is provided with two one-way valves on the basis of an original combustion engine automobile crane. One one-way valve is connected in series with an original oil pump, and the other one-way valve is connected with an oil pump driven by a motor. The motor can be selected with an explosion-proof type. The power auxiliary driving mechanism for a combustion engine automobile crane can directly enter a reservoir region with hazardous articles to work, such as a meadow.
Description
The utility model relates to a kind of internal-combustion engines vehicle hoisting crane electric power assistive drive mechanism.
Existing internal-combustion engines vehicle hoisting crane, owing to use the mono-internal combustion engine drive, can not be fire-proof and explosion-proof, can not enter grassland class dangerous material reservoir area operation.
The purpose of this utility model provides a kind of internal-combustion engines vehicle assistive drive mechanism that can enter grassland class dangerous material reservoir area operation with fire-proof and explosion-proof performance.
The utility model is achieved through the following technical solutions.
Connecting on the hoisting crane of oil pump driving by change speed gear box by combustion engine, two check valves in parallel of installation between the outlet of this oil pump and hoisting crane maneuvering valve, one of them check valve is connected with original oil pump, another check valve connects one by electric motor driven oil pump, and the fuel tank switch that is connected oil filter on import and the fuel tank is connected.
Because the utility model is provided with power-actuated oil pump on the internal-combustion engines vehicle hoisting crane, can be under the out-of-run situation of combustion engine, use direct motor drive, electrical motor can be selected explosion-proof kind routinely, thereby more original car hosit had fire-proof and explosion-proof performance, can directly enter grassland class dangerous material reservoir area operation.
Accompanying drawing is a structural representation of the present utility model.
Internal-combustion engines vehicle hoisting crane shown in the drawings electric power assistive drive mechanism, internal-combustion engines vehicle driving engine 3 connects oil pump 4 by change speed gear box 7, the import of oil pump 4 is connected with fuel tank switch 13 oil filters 2 fuel tanks 1, oil pump 4 outlets are connected with the upper and lower manipulation distributing valve of car hosit, the utility model is provided with the check valve 6 and the check valve 11 of two parallel connections in the outlet of oil pump 4, check valve 11 connects an oil pump 8 that is driven by electrical motor 9, and the import of oil pump 8 is connected with fuel tank switch 13.By electric appliance control box 12 controls, the outlet of oil pump 8 and oil pump 4 has by pass valve 10 and by pass valve 5 respectively to electrical motor 9 routinely routinely.
