Description

Technical Field

[0001] The utility model belongs to the technical field of drilling rig trolleys, and more specifically, relates to a heating system for a drilling rig trolley. Background Art

[0002] A self-propelled underground drilling rig trolley is an engineering machinery equipment that performs mining operations below the surface. Common underground drilling rig trolleys usually include two power systems, one of which is an engine system for driving the drilling rig trolley to move, and the other is an electric pump station system that uses an electric motor to drive a hydraulic pump for excavation or mining operations. The more traditional heating method for the drilling rig trolley cab is to heat it through the heat source of the engine cooling water tank, but due to the underground working environment, the underground drilling rig trolley moves less frequently and usually operates in a fixed location. Therefore, the engine system used to drive the drilling rig trolley to move is in a shutdown state for a long time, resulting in a cab that cannot be heated. In actual production, in order to solve the above problem, an electric air conditioner is set in the cab for heating, but the use of the electric air conditioner will consume the power of the main power supply of the drilling rig trolley, resulting in a shorter operating time of the electric pump station system used for excavation or mining operations, thereby reducing the underground operation efficiency.

[0028] In this embodiment, the rock drill is the main excavation equipment on the drilling rig trolley.

During operation, the hydraulic oil flows through the hydraulic rotary motor 3. The hydraulic oil flows into the motor control valve 4 through the first liquid supply pipeline 21. The motor control valve 4 controls the action of the hydraulic swing motor 3 by controlling the amount of hydraulic oil flowing into the oil inlet of the hydraulic swing motor 3. The temperature of the hydraulic oil entering the hydraulic swing motor 3 will increase after driving the hydraulic swing motor 3 to do work. The heated hydraulic oil enters the motor control valve 4 through the second liquid inlet, and is then discharged into the first return liquid pipeline 23 through the first return liquid port.
