Embodiment

[0024] Crane is under normal working condition, works by braking wheel 15, brake 16 and hydraulic pusher 17. When the power is suddenly cut off, the electric push rod starts to work through the battery 11, and then drives the push rod to swing, and then pushes the extension plate 1 to swing, thereby driving the hydraulic pusher 17 to move up and down, so that the brake shoe of the brake 16 and the brake wheel 15 Separation, and then realize the control of the size of the friction force, so that the workpiece on the hook head can enter the oil groove smoothly. The operator works in the control room, controls the ascending and descending speed, and installs a limit switch on the limit position of the connecting rod 3 to ensure that the ejector rod 2 works within a safe range.

Abstract

The invention discloses an electric brake releasing mechanism of a quenching bridge crane. According to the crane, a hydraulic driver controls a brake wheel to work through a brake; an extending plate is fixedly connected to the output end of the hydraulic driver; a fixed frame is welded to the crane and provided with an electric push rod; and the top end of the electric push rod is fixedly connected with an ejector rod and a connecting rod. The power input end of the electric push rod is connected with a storage battery. The tail end of the electric push rod is connected with the fixed frame through a first pin shaft, and the top end of the electric push rod is connected with the front end of the connecting rod through a second pin shaft. The brake releasing mechanism is mounted on a lifting transmission mechanism of the quenching bridge crane, the working principle of an original crane is not changed, and the unintermittent storage battery is used for energy storage. When power is lost suddenly, the energy of the storage battery can be utilized for starting the brake releasing mechanism, a hydraulic push rod of the brake of the crane is pushed, a workpiece stably enters an oil tank, and the aim of fire extinguishment is achieved.

Description

technical field [0001] The invention relates to an electric brake release mechanism of a quenching bridge crane, which belongs to the technical field of heat treatment and quenching. Background technique [0002] The quenching process is a heat treatment process to improve the mechanical properties of metal materials. Some alloy steel parts must be heated to a high temperature state and then cooled in quenching oil to obtain the corresponding structural properties. The bridge crane used for heat treatment and quenching, when the hot workpiece is hung by the hook for oil cooling and quenching, due to various uncertain factors, the crane suddenly cuts off the power, and the workpiece is located above the quenching oil tank, and the oil temperature on the surface of the oil tank is instantly reduced. When it rises above the flash point, the oil surface catches fire immediately, producing a large amount of oily smoke and oil vapor, which burns again on the surface of the workpie...
