Abstract
The utility model discloses a work braking device for a hoisting reel cart, which comprises a braking wheel and two brake-arms; the lower ends of the two brake-arms are fastened respectively on the base, and the upper ends are hinged with an oil pressure spring push pole. The oil pressure spring push pole is formed in the way that a pressure spring is installed in the sleeve, a pull-rod threads through the middle of the spring, one end of the pull-rod stretches out freely from the left end of the sleeve and gets connected with a hinged head, the other end is propped up with a big screw nut. A hydraulic ram is fixed on the right end inside the sleeve, the ram piston pole cap props up the pull-rod; a reamer ear is fixed on the right end outside the sleeve, the hydraulic ram is controlled by an electro-hydraulic proportional valve, which is connected to a control valve with a fuel pipe. The valve of the control declutch of the electro-hydraulic proportional valve applying for passing is used with spring strength, the operation is automatic, the size of the working brake moment can be controlled flexibly by the spring, the movement is agile, the model is safe, the structure is compact and simple, maintenance and installation of the model is simple.
Description
Technical field
The application belongs to elevating gear, relates in particular to the brake equipment of lifting winch.
Background technology
At present on the lifting winch (gig) of industries such as mine, building, service braking adopts manpower lever's brake equipment of band brake type, it comprise between motor and the change speed gear box brake wheel and about the lock arm of two band brake shoes, the lower end of two lock arms is hinged on the base respectively, the upper end is hinged on respectively on two adjacent fulcrums of a culdy, by manual operation lever far-end, reach the purpose that declutches and make lock, thus operation of control lifting winch or parking.This service braking mode, labour intensity is big, the fault rate height.
Summary of the invention
The application's purpose is the deficiency that overcomes manual machine control lever, designs a kind of lifting winch service brake with oil pressure control.
The application's technical scheme is, comprise brake wheel and about the lock arm of two band brake shoes, the lower end of two lock arms is separately fixed on the base, the upper end is hinged on respectively on the hydraulic spring push rod.
The hydraulic spring push rod is the application's a technical characterictic, it comprises oil cylinder, sleeve pipe, pull bar, spring, concrete structure is: pressure spring is housed in sleeve pipe, pass a pull bar in the middle of the pressure spring, pull bar one end freely stretches out from the sleeve pipe left end, be threaded on the drawhead that stretches out and go up articulated joint, be used for the lock arm hingedly, the pull bar other end withstands spring with a big nut; Right-hand member in sleeve pipe is fixed a hydraulic ram, and the piston rod of hydraulic ram withstands on the pull bar; Cut with scissors ear on the outer right-hand member captive joint of sleeve pipe, be used for right lock arm hinged.Hydraulic ram is controlled with electro-hydraulic proportional valve, and electro-hydraulic proportional valve is connected on the control cock with oil pipe.
During use, operating cylinder makes the piston masthead move pull bar to stretch out, the lock arm is unclamped; Piston rod withdrawal is withdrawn in the sleeve pipe pull bar under spring support power, the lock arm is held tightly.Adjust the braking force of the big nut setting band-type brake on the pull bar.
The application is owing to adopt declutching and making lock of hydraulic spring push rod control sluice arm, so following good effect is arranged: the one, declutch by electro-hydraulic proportional valve control, and make lock by spring force, operation automation; The 2nd, by the spring size of Control work lock torque flexibly, be active in one's movements, safety is good; The 3rd, this apparatus structure is compact simple, safeguards easy for installation.
Description of drawings
Fig. 1 is embodiment integral structure figure, and Fig. 2 is the structure cutaway view of embodiment critical component hydraulic spring push rod, and Fig. 3 is the left view of Fig. 1.
