Abstract
The utility model discloses a dual-power hydraulic system of a spraying mechanical arm frame, which comprises a main power system and an emergency power system. The main power system comprises a motor, a main oil pump and an arm frame pump, wherein the main oil pump and the arm frame pump are connected with the motor, and the emergency power system comprises a vehicle-mounted engine, a running pump connected with the engine and a two-position three-way valve; and a first inlet of the two-position three-way valve is connected with the running pump, a second inlet of the two-position three-way valve is connected with the arm frame pump through a one-way valve, and the outlet of the two-position three-way valve is connected with a cylinder of the hydraulic system of the arm frame. By adopting the dual-power hydraulic system, the spraying mechanical arm frame can operate more reliably, the continuous operation of the spraying arm frame can be guaranteed, and no effect can be caused on operation of the spraying arm frame. Moreover, with the dual-power hydraulic system, the spraying mechanical arm frame can be operated conveniently and rapidly. When the arm frame fails and cannot operate normally, the arm frame can be smoothly folded to ensure that a whole vehicle can conveniently depart from a tunnel.
Description
Technical field
The utility model belongs to fluid power system, and being specifically related to a kind ofly can provide double dynamical hydraulic system for the jet robot jib.
Background technology
Construction along with our national high-speed railway, the tunnel of excavation is more and more, the use of jet robot also more and more widely, the work of jet robot mainly is to utilize its jib to carry out concrete to spray, the driving of jet robot jib is controlled by hydraulic system.At present, the hydraulic system of the driving jib of jet robot all has only power set both at home and abroad, and an arm-pump drives the jib each several part and folds by driven by motor, finishes various injection action.In case the jet robot power that its hydraulic system provides in work progress goes wrong, not only concrete injection work can not be carried out, and all can run into obstacle even car load removes construction tunnel.
The utility model content
The purpose of this utility model provides a kind of jet robot jib double-power hydraulic system, and this system has better reliability, can prevent that the situation that the jet robot jib causes because of a power breaks down working from taking place.
The technical scheme that realizes the utility model purpose is, jet robot jib double-power hydraulic system, comprise a main power system, main power system comprises motor, the main oil pump that is connected with motor and arm-pump, also comprise an emergency power system, the emergency power system comprises on-board engine, the traveling pump that is connected with motor, two position three-way valve; First inlet of described two position three-way valve is connected with traveling pump, and second inlet is connected with arm-pump by one way valve, and the outlet of two position three-way valve is connected with the oil cylinder of jib hydraulic system.
The utility model is to increase by one tunnel power resources as emergency power on original injection jib dynamical system, and this power directly utilizes vehicle-mounted motor and traveling pump.The jet robot jib is when operate as normal, and the arm-pump in the main power system drives the jib each several part and moves by driven by motor.When motor or arm-pump breaks down or when having a power failure suddenly, the emergency power system begins to start, and only need open two position three-way valve, makes traveling pump provide power to boom system, guarantee that jib is normally folding, make jet robot shift out the tunnel smoothly.Avoid delaying production, influence the duration progress.
Owing to adopt the double-power hydraulic system, make the work of jet robot jib more reliable, guaranteed that the injection jib can continuous action, can not exert an influence to work, and double dynamical selection that operation is very easy is quick.Go wrong in the jib injection, can fold smoothly during cisco unity malfunction, the assurance car load is left the tunnel easily.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, jet robot jib double-power hydraulic system, comprise a main power system, main power system comprises motor 1, the main oil pump 2 that is connected with motor 1 and arm-pump 3, also comprise an emergency power system, the emergency power system comprises on-board engine 5, the traveling pump 6 that is connected with motor 5, two position three-way valve 7; First inlet of two position three-way valve 7 is connected with traveling pump 6, and second inlet is connected with arm-pump 3 by one way valve 7, and the outlet of two position three-way valve 7 is connected with the oil cylinder 9 of jib hydraulic system, and arm-pump 3 also is connected with chassis 8.
The jet robot jib is when operate as normal, and arm-pump 3 drives by motor 1, drives the jib each several part and moves.When motor 1 or arm-pump 3 break down or have a power failure suddenly, can open two position three-way valve 7 and start the emergency power systems, make traveling pump 6 provide power to boom system, guarantee that jib is normally folding, make jet robot shift out the tunnel smoothly.Avoid delaying production, influence the duration progress.
Concrete sprayer tool hand makes the service behaviour of complete machine more reliable, easy to operate owing to adopt double dynamical boom system, because hydraulic system adopts standard component to connect, helps maintenance and maintenance, for concrete injection provides powerful guarantee simultaneously.
