A horizontal wheel side brake for gantry crane

Abstract

The present invention relates to the field of electric wheel brakes, in particular to a horizontal wheel brake for gantry cranes, which includes a mouth bracket, a friction plate and a deceleration motor, and also includes: a screw moving assembly, a screw moving assembly Set in the mouth bracket, the deceleration motor is set on the mouth bracket, and its output shaft is connected with one end of the input shaft of the screw moving assembly; the clamping claw assembly, the opening of the clamping claw assembly is arranged radially and horizontally along the wheel edge On the outside of the mouth bracket, the clamping claw assembly includes a drive rod, which is connected to the working end of the screw rod moving assembly, and the friction plates are arranged on both sides of the clamping mouth of the clamping claw assembly; the return spring, the return spring is coaxially sleeved On the driving rod; the torsion spring is sleeved on the other end of the input shaft of the screw rod moving assembly, and the two ends of the torsion spring are respectively fixedly connected to the inner side of the mouth support and the circumferential surface of the input shaft of the screw rod moving assembly. The wheel brake can Automatically brakes when power is off, and can be installed horizontally on a gantry crane.

Description

technical field [0001] The invention relates to the field of electric wheel brakes, in particular to a horizontal wheel brake used for a gantry crane. Background technique [0002] The gantry crane is a large-scale machine widely used in railway freight yards, ports, docks and other places for loading and unloading large and heavy goods and containers. With the development of the domestic economy, the market demand for gantry cranes is becoming more and more strong. However, in the strong convective weather in coastal areas, sudden sudden strong winds often occur, and the dynamic wind protection device sometimes cannot guarantee reliable braking and stop the crane as a whole, causing major safety accidents. [0003] In recent years, there have been frequent incidents of collapse caused by sudden strong winds during the operation of coastal gantry and gantry cranes, resulting in casualties and huge economic losses. Since both the operator and the mechanical equipment are thr...
