Problems solved by technology

During the use of the external brake, the friction between the external brake assembly and the brake will generate heat, which will cause slippage between the external brake assembly and the brake, which will bring great safety hazards to production and affect production efficiency. The friction belt of the brake assembly is worn, reducing the service life of the friction belt

Embodiment Construction

[0014] Referring to Fig. 1, an external brake is installed on the wheel hub 2 on one side of the wire rope drum 1 of the grab-type grabbing crane, wherein the external brake includes a brake 3 mounted on the drum hub 2 and an external brake mounted on the brake 3. Brake assembly 4.

[0015] As shown in the figure, a cooling chamber 5 is provided in the wire rope drum brake 3, a water inlet chamber 6 communicating with the cooling chamber 5 is provided in the hub 2 of the drum 1, and a Sealing ring 7. A water outlet chamber 8 is also arranged in the hub 2, and a water chamber partition 9 is arranged between the water outlet chamber 8 and the water inlet chamber 6. The cooling chamber 5 and the water outlet chamber 8 communicate through the water outlet hole 10 arranged on the hub 2, and the water The cavity partition 9 can prevent the cooling water from being disturbed in the whole cooling process, so that it flows according to the route of cold in and hot out, so as to achiev...

Abstract

The invention discloses an external brake water cooling device of a grabbing bucket typed grabbing and digging crane, characterized in that the device comprises a cooling chamber arranged inside a brake of a steel wire rope roller, an intake chamber and an outlet pipe communicated with the cooling chamber; the intake chamber is arranged inside a hub of the roller; one end of the outlet pipe is arranged inside another hub of the roller; an inlet end of the intake chamber and an outlet end of the outlet pipe are provided with rotating joints; the invention can timely take away the heat generated due to friction between an external brake assembly and the brake, prevent slipping phenomenon caused by heat accumulation between the external brake assembly and the brake, eliminate security hidden troubles, facilitate continuous work of the brake system, increase production efficiency, avoid wear of a friction belt of the external brake assembly and prolong the service life of the friction belt.

Description

technical field [0001] The invention relates to a water cooling device, in particular to a water cooling device applied to the outer brake of a grab type grab digging crane. Background technique [0002] At present, a grab crane is usually used as an excavating machine on a grab and dig engineering ship. The transmission mechanism of this grab crane is usually equipped with an external brake, and the brake is braked by controlling the external brake assembly of the external brake to achieve The purpose of stopping the movement of the hoisting mechanism of the crane. During the use of the external brake, the friction between the external brake assembly and the brake will generate heat, which will cause slippage between the external brake assembly and the brake, which will bring great safety hazards to production and affect production efficiency. The friction belt of the brake assembly is worn, reducing the service life of the friction belt. Contents of the invention [00...
