Pneumatic crawler-type forklift and method

Abstract

The invention discloses a pneumatic crawler-type forklift and a method. The forklift comprises a walking crawler assembly, a forklift door frame assembly, a vehicle chassis and an operation table, the operation table is located above the front portion of the vehicle chassis, the vehicle chassis is installed on the walking track assembly, a pneumatic motor and a gear oil pump are installed in the vehicle chassis, an output shaft of the pneumatic motor is connected with an input shaft of the gear oil pump, an oil conveying pipeline of the gear oil pump is separately connected with a lifting oil cylinder and an inclined oil cylinder, a multi-way reversing valve set is arranged on the oil conveying pipeline of the gear oil pump, the operation table comprises a supporting frame and a multi-way reversing valve control rod, and the multi-way reversing valve control rod is connected with the multi-way reversing valve set. According to the pneumatic crawler-type forklift provided by the embodiment of the invention, a crawler-type traveling mechanism is adopted, hydraulic transmission is achieved, the gradeability is high, braking is reliable, and the pneumatic crawler-type forklift adapts to severe road surfaces of underground tunneling roadways.

Description

technical field [0001] The invention belongs to the field of mining auxiliary transport vehicles, and in particular relates to a pneumatic crawler forklift and a method thereof. Background technique [0002] Existing auxiliary transportation vehicles in modern mines and coal mines use explosion-proof diesel rubber-tyred vehicles, which have high fuel consumption, environmental pollution caused by diesel combustion exhaust, and even excessive carbon monoxide safety issues. During operation, after the explosion-proof diesel truck transports the materials required for the excavation working face and mining working face to the underground working roadway, it cannot directly transport the materials to the working face, and often the remaining distance of at least 200 meters requires manual removal of the bolts required for the working face. , anchoring agent, pipelines, pallets, anchor cables and other support materials and tools are carried to the working position, the work effi...
