Problems solved by technology

The track leveling control system of the traditional drilling rig only uses a combination of hydraulic handle and hydraulic lock balance valve to control the actuator, which can realize the basic track leveling function and complete the action, but when it is necessary to achieve a variety of different leveling actions, it needs Adding multiple handles to control, which causes problems such as large space occupation and inaccurate leveling. The mechanical handle is forgotten to reset when the machine is turned off, resulting in static action of the leveling mechanism, which also brings inconvenience to the drilling rig operator.

Embodiment 1

[0028] Such as Figure 1-6 , a track leveling control system of a drilling rig, which includes a power mechanism 7 , the power mechanism 7 is connected to a track leveling valve group 8 , and the track leveling valve group 8 is connected to an actuator 23 . The hydraulic power provided by the power mechanism 7 can provide power for the track leveling system, the action of the corresponding solenoid valve can be controlled by the track leveling valve group 8 , and then different actions can be implemented, and the corresponding action can be realized by the actuator 23 .

[0029] Further, the power mechanism includes a variable displacement pump 3, and the variable displacement pump 3 is connected to two parallel first load pressure sensitive control valves 4 and second load pressure sensitive control valves 5; the oil inlet pipe of the variable displacement pump 3 is connected to the The oil tank 1 is connected and a check valve 2 is connected in parallel on the oil inlet pipe...

Embodiment 2

[0035] Using any one of the track leveling control system adjustment control methods, it is characterized in that it includes:

[0036] Step 1: By supplying power to Y1 / Y2 / Y3 / Y4 of the four two-way stop solenoid valves 15, 16, 17, 18, Y5 / Y6 of the three-position four-way electromagnetic reversing valve 9 is not powered, so that the actuator The left leveling oil cylinder 24 and the right leveling oil cylinder 25 of 23 are connected. When the road surface is uneven during walking, one oil cylinder is compressed, and the oil fluid flows to the other oil cylinder through the track leveling valve group 8, and the other Only the oil cylinder is stretched out accordingly, so that the floating is the body balance;

[0037] Step 2: By supplying power to Y1 / Y2 of the two-way cut-off solenoid valves 15 and 16, and Y5 or Y6 of the three-position four-way electromagnetic reversing valve 9, the left leveling cylinder 24 can independently expand and contract;

[0038] Step 3: By supplying ...

Abstract

The invention relates to a track leveling control system for a drill carriage and an adjusting control method. The track leveling control system comprises a power mechanism connected with a track leveling valve set. The track leveling valve set is connected with an execution mechanism. The various different functions can be achieved. A carriage body can keep balanced automatically when a chassis meets an uneven pavement or a pot hole pavement. The composite functions of single control, whole locking and the like can be further achieved through on-off control of electromagnetic valves. Pumps ofthe track leveling control system are in a standby energy-saving state when the execution mechanism does not make actions, and the pumps provide the needed flow of a loading mechanism when the execution mechanism is controlled to make the actions, so that the energy-saving and environment-friendly effects are achieved.

Description

technical field [0001] The invention belongs to the field of drilling rig hydraulic control systems, and in particular relates to a crawler belt leveling control system and an adjustment control method of a drilling rig. Background technique [0002] Hydraulic rock drills are widely used in mining, tunneling and engineering construction, and there are more and more researches on the automatic control system of rock drills at home and abroad. The track leveling control system of the traditional drilling rig only uses a combination of hydraulic handle and hydraulic lock balance valve to control the actuator, which can realize the basic track leveling function and complete the action, but when it is necessary to achieve a variety of different leveling actions, it needs Adding multiple handles to control will cause problems such as large space occupation and inaccurate leveling. The mechanical handle is forgotten to reset when the machine is turned off, resulting in static actio...
