A hydraulic support truck

Abstract

The invention relates to fully-mechanized coal mining equipment of a coal mine and particularly relates to a hydraulic bracket transportation vehicle. The hydraulic bracket transportation vehicle comprises a front vehicle and a rear vehicle which are mutually hinged, wherein the front vehicle is provided with a driving device for driving the transportation vehicle to move; the rear vehicle is hinged with the front vehicle by a hinging device; the rear vehicle is provided with a bracket hanging and unloading device for bearing a hydraulic bracket; the hinging device comprises a central rotary mechanism, a rotary sleeve, a rotary shaft, a locking assembly, an end cover and a joint bearing; one end of the rotary shaft is inserted into the rotary sleeve and is rotationally connected with the rotary sleeve by a bearing; the rotary shaft is located at the other end on the outer part of the rotary sleeve and is in key connection with the central rotary mechanism; the central rotary mechanism is provided with the joint bearing connected with the front vehicle; the rotary sleeve is connected with the rear vehicle; one end of the rotary sleeve and the rotary shaft are sealed; the other end of the rotary sleeve is connected with the end cover in a sealed manner; the locking assembly is arranged at one end of the rotary shaft. The hydraulic bracket transportation vehicle has strong adaptability and can be suitable for coal tunnels with different working conditions; the hydraulic bracket transportation vehicle has reliable performances and a wide view field and is convenient to maintain.

Description

technical field [0001] The invention relates to coal mine fully mechanized mining equipment, in particular to a hydraulic support transport vehicle. Background technique [0002] At present, trackless rubber-tyred vehicles are mainly used for efficient transportation of fully mechanized mining equipment. Due to the large tonnage of fully mechanized mining equipment, long transportation distances, narrow coal mine transportation and installation roadways, dark light, and poor road conditions, it has caused great difficulties for the transportation of large fully mechanized mining equipment, especially long-distance transportation. Wherein the support carrier is the main equipment for transporting the hydraulic support, the existing support carrier has poor adaptability, and has been unable to meet the requirements of various road conditions under the coal mine. Contents of the invention [0003] The object of the present invention is to provide a hydraulic support truck wi...

Problems solved by technology

Due to the large tonnage of fully mechanized mining equipment, long transportation distances, narrow coal mine transportation and installation roadways, dark light, and poor road conditions, it has caused great difficulties for the transportation of large fully mechanized mining equipment, especially long-distance transportation.

Among them, the support truck is the main equipment for transporting hydraulic supports. The existing support truck has poor adaptability and can no longer meet the requirements of various road conditions in coal mines.
