Description

Technical Field

[0001] This utility model relates to the field of hydraulic control system technology, and in particular to a composite motion control system for a digital handle switch of an anchor drilling rig. Background Technology

[0002] With the nation's massive investment in infrastructure, slope anchoring operations have increased significantly, leading to the emergence of anchor bolt (anchoring) drilling rigs. These rigs replace manual labor, reducing operational difficulty and risk, and have become crucial equipment in engineering infrastructure projects. Currently, digital technology is being widely applied, and digital handle switches are extensively used in anchor bolt (anchoring) drilling rigs. Most anchor bolt (anchoring) drilling rig operation modes are currently derived from improvements to existing excavators. Traditional excavators have fewer operating actions, while anchor bolt (anchoring) drilling rigs have more functions and more operating actions. The traditional approach involves adding corresponding digital handle switches to perform each action, resulting in a cab cluttered with various handle switches, increasing the operator's difficulty. The numerous and widely distributed handles also make continuous operation inconvenient, significantly reducing efficiency and work productivity, and increasing the risk of potential malfunctions.

[0003] Therefore, it is necessary to provide a composite motion control system for the digital handle switch of the anchor drilling rig to solve the above-mentioned technical problems. Utility Model Content

[0004] In view of the above situation, in order to overcome the shortcomings of existing technologies that have too many digital handle switches and are inconvenient to operate, this utility model provides a composite action control system for digital handle switches of anchor drilling rigs, which optimizes operation, reduces panel switches, and simplifies operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The composite motion control system of the digital handle switch of the anchor drilling rig includes: a mode switch M, used to output chassis mode signal and drilling mode signal; and a digital cross handle switch K, which is connected to the controller H via a CAN line and used to send directional operation signal to the controller H. Pins 8 and 9 of controller H are connected to the chassis mode signal line and drilling mode signal line of mode switch M, respectively, for receiving mode signals; the electro-proportional output E is defined as pins 99 and 25 of controller H and connected to electro-proportional valve Q; the electro-proportional output F is defined as pins 40 and 16 of controller H and connected to electro-proportional valve G; the multi-way valve A has its push port b2 connected to port b3 of electro-proportional valve Q and its main port B2 connected to cylinder C; the multi-way valve B has its push port b1 connected to port b4 of electro-proportional valve G and its main port B1 connected to cylinder D; when the digital cross handle switch K is operated to the left: when mode switch M is in chassis mode, controller H drives electro-proportional output E according to the signal from pin 8 and the left-turn signal, causing cylinder C to move; when mode switch M is in drilling mode, controller H drives electro-proportional output F according to the signal from pin 9 and the left-turn signal, causing cylinder D to move.

[0007] Preferably, the four directional operation signals of the digital cross handle switch K are combined with the two sets of signals of the mode switch M to achieve eight different hydraulic action outputs.

[0008] Preferably, the electro-proportional output E and the electro-proportional output F are current proportional signals used to drive the opening proportional control of the electro-proportional valves Q and G.

[0009] Preferably, the multi-way valve A and multi-way valve B are hydraulically controlled multi-way valves, and the opening and closing of their main oil circuits is driven by the hydraulic oil output from the electro-proportional valves Q and G.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention reduces the number of panel operation handle switches, saving costs; optimizes operation, making operation simpler with fewer panel switches; has a simple structure, making it easy for operators to master; the reduction of handle switches makes it easier to achieve coordinated operation of several actions, saving time and increasing efficiency; and the reduction of digital handle switches reduces the risk of malfunction.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0019] like Figure 1-6 As shown, the composite action control system of the digital handle switch for the anchor drilling rig provided by this utility model includes: the chassis mode signal line of the mode switch M is connected to pin 8 of the controller H, and the drilling mode signal line is connected to pin 9. The mode switch is a two-position switch that outputs high / low level signals.

[0020] The digital cross handle switch K communicates with the controller H via the CAN bus, and its signals in the four directions of left, right, forward, and backward are all transmitted to the controller H.

[0021] Electro-proportional output E: The positive terminal (pin 99) and negative terminal (pin 25) of the controller output current signals, which are connected to the coil of the electro-proportional valve Q. The outlet b3 of the electro-proportional valve Q is connected to the actuation port b2 of the multi-way valve A via a hydraulic line.

[0022] Electro-proportional output F: The positive terminal (pin 40) and negative terminal (pin 16) of the controller output current signals, which are connected to the coil of the electro-proportional valve G. The outlet b4 of the electro-proportional valve G is connected to the push port b1 of the multi-way valve B.

[0023] The main oil port B2 of multi-way valve A is connected to cylinder C, and the main oil port B1 of multi-way valve B is connected to cylinder D. Cylinder C and cylinder D are used to control the movement of the support arm and drill arm of the anchor drilling rig, respectively.

[0024] The specific operation is as follows: Connect the chassis and drilling signal lines of mode switch M to pins 8 and 9 of the YPC controller, respectively. Add an electro-proportional output F, defined as pins 40 and 16. Connect electro-proportional output F to electro-proportional valve G. Connect the corresponding oil circuit interface b4 of electro-proportional valve G to the push port b1 of multi-way valve B. Connect the main oil port B1 of multi-way valve B to cylinder D. Keep the existing electro-proportional output E unchanged, defined as pins 99 and 25. Connect electro-proportional output E to electro-proportional valve Q. Connect the corresponding push port b3 of electro-proportional valve Q to the push port b2 of multi-way valve A. Connect the main oil port B2 of multi-way valve A to cylinder C. The digital cross handle switch K is connected to controller H via a CAN line. When the digital cross handle switch K is operated to the left, a leftward digital signal is output and transmitted to the controller H via the CAN bus. When the mode switch M is in chassis mode, the controller receives a signal at pin 8. The edit command is the leftward digital signal + the signal at pin 8. Then, pins 99 and 25 output the electro-proportional output E. The electro-proportional output E activates the solenoid valve circuit of the electro-proportional valve Q. The electro-proportional valve Q outputs oil through port b3, which connects to the actuation port b2 of the multi-way valve A connected to port b3. This activates the main oil circuit output B2 of the multi-way valve A, driving the hydraulic cylinder C to work, thus realizing one-way operation. Action output; Similarly, when the digital cross handle switch K is still operating to the left, it outputs a left-direction digital signal, which is transmitted to the controller H via the CAN line. When the mode switch M is in drilling mode, pin 9 of the controller receives a signal. The edit command left-direction digital signal + pin 9 signal then outputs an electro-proportional output F from pins 40 and 16. The electro-proportional output F activates the solenoid valve circuit of the electro-proportional valve G. The electro-proportional valve G correspondingly pushes the oil port b4 to output oil, which in turn activates the oil circuit of the multi-way valve B. The main oil circuit B1 of the multi-way valve B is then activated, driving the cylinder D to work, thus achieving another action output. In this way, the handle switch can output two actions when it is operated in one direction. Similarly, the digital cross handle switch can achieve eight different actions using the same method in four directions, saving half the number of switches.
