Embodiment 1

[0023] Embodiment 1: as Figure 1-Figure 3 As shown, an auxiliary supporting device for extending the top beam of a hydraulic support includes an extended top beam 2 fixedly connected to the front end of the telescopic beam 1, and a vertical hydraulic cylinder 3 is arranged at the bottom end of the extended top beam 2, and the lower end of the hydraulic cylinder 3 leans against the On the shovel plate 4, the present invention is supported under the extended top beam through a hydraulic oil cylinder to play an auxiliary supporting role, which can greatly improve the support bearing capacity of the coal mining face, and avoid the extended top caused by the excessive moment caused by the excessively long telescopic beam of the top beam. Beam damage and safety accidents are prone to occur, the equipment safety and use safety are higher, the service life is longer, the support surface is wider, and it is more conducive to rapid coal mining, and the coal mining production efficiency ...

Embodiment 2

[0029] Embodiment 2: An operation method of an auxiliary support device for a hydraulic support with a lengthened top beam, the method includes the following steps:

[0030] (1) Put the upper end of the hydraulic cylinder against the connection between the extended top beam and the telescopic beam, and place it vertically on the shovel;

[0031] (2) Start the hydraulic cylinder, when its oil pressure reaches more than 1.2 times the oil pressure of the balance cylinder of the hydraulic support, keep the oil pressure, and the hydraulic cylinder provides auxiliary support for the extended top beam;

[0032] (3) After the support is completed, close the oil inlet of the hydraulic cylinder, start the auxiliary hydraulic cylinder, push the hydraulic cylinder to rotate around the hinge axis through the lever of the auxiliary hydraulic cylinder, and store it under the telescopic beam;

[0033] (4) Transport the scraper machine under the telescopic beam.

Abstract

The invention discloses a hydraulic support lengthened top beam auxiliary support device which comprises a lengthened top beam connected with the front end of a telescopic beam fixedly, wherein the bottom end of the lengthened top beam is provided with a vertical hydraulic cylinder; the lower end of the hydraulic cylinder props against a shovel plate. The hydraulic support lengthened top beam auxiliary support device supports the lengthened top beam by virtue of the hydraulic cylinder, so that an auxiliary support effect is achieved, the support bearing capacity of a coal face can be greatly improved, a lengthened top beam damage and a high possibility of safety accidents caused by overlarge torque caused by an overlong telescopic beam of the top beam are avoided, the equipment safety and the use safety are relatively high, the service life is relatively long, the supporting surface is relatively wide and is relatively beneficial for rapid coal mining, and the coal mining production efficiency is greatly improved. The hydraulic support lengthened top beam auxiliary support device also has the characteristics of simple structure, low cost, convenience and rapidness for assembly, disassembly and maintenance, and greatly lowered maintenance cost.

Description

technical field [0001] The invention relates to an auxiliary supporting device for extending a top beam of a hydraulic support and an operation method thereof, belonging to the technical field of hydraulic supports. Background technique [0002] After the hydraulic support for mining equipment is equipped with an extended top beam on the telescopic beam, the load-bearing capacity and cantilever moment of the top beam bearing place will be greater, and the rigidity of the cantilever end will cause the equipment to be damaged and the safety of the equipment will be poor. The operating safety of the operator cannot be guaranteed, the service life of the equipment is relatively short, and the production efficiency is also low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an auxiliary supporting device for extending the top beam of the hydraulic support and its operation method, which can realize the support bearin...
