For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Refer to the following Figure 1 and Figure 2The present invention describes a prime mover combination control device and a rotary drilling rig according to some embodiments of the present application.

[0034] The present application provides a prime mover combined control device, such as Figure 1 As shown, it includes a control key and a controller, wherein the control key includes a push button switch 2 and a knob switch 1. The push button switch 2 can be used to turn on and off the power of the electrical equipment of the engineering vehicle including the prime mover of the engineering vehicle; the knob switch 1 is connected to the prime mover through communication with the controller, and the operator can start the prime mover and shift the prime mover by operating the knob switch 1.

[0035] In this embodiment, preferably, Figure 1 As shown, the knob switch 1 is annular, and the annular knob switch 1 is arranged around the outside of the push switch 2; the push switch 2 is the on / off button of the prime mover, and the push switch 2 has a first working position and a second working position. Pressing the push switch 2 can switch the push switch 2 between the first working position and the second working position; when the push switch 2 is engaged in the first working position, the prime mover is in a power-off state, and pressing the push switch 2 downward can engage the push switch 2 in the second working position and keep the push switch 2 in the second working position, and the prime mover is in a power-on state; pressing the push switch 2 downward again will return the push switch 2 to the first working position, and the prime mover will be powered off.

[0036] Preferably, if Figure 1 As shown, a status indicator light 7 is provided on the button end face of the button switch 2. When the button switch 2 is located in the first working position, the status indicator light 7 is off. When the button switch 2 is engaged in the second working position, the status indicator light 7 will be lit. Thus, the working position of the button switch 2 can be determined by the state of the status indicator light 7, and further, whether the prime mover is in a powered state can be determined.

[0037] Before the operator starts the prime mover, the key switch 2 is engaged in the first working position, the prime mover is in a power-off state, and the status indicator light 7 is in an off state; the operator presses the key switch 2 downward to engage the key switch 2 in the second working position, so that the prime mover is powered on and the status indicator light 7 is in a lit state; thereafter, the prime mover can be started and gear shifting operations can be performed during driving; when it is necessary to stop the vehicle, the operator presses the key switch 2 downward again, and the key switch 2 returns to the first working position, and the prime mover is powered off and shut down.

[0038] In this embodiment, preferably, the knob switch 1 has a plurality of working gears, and rotating the knob switch 1 can switch the knob switch 1 between different working gears, so as to control the prime mover to perform corresponding operations through the controller.

[0039] Preferably, the multiple working gears of the knob switch 1 include a starting gear, an idle gear and multiple speed regulating gears; the starting gear, the idle gear and the multiple speed regulating gears are spaced in sequence along the clockwise direction, that is, the right-hand direction of the knob switch 1, the idle gear is adjacent to the starting gear, and the multiple speed regulating gears increase step by step along the clockwise direction.

[0040] When the prime mover is powered on, when the operator rotates the knob switch 1 to the start gear position, the prime mover will ignite and start under the control of the controller. It should be noted that after the prime mover is started, when the operator rotates the knob switch 1 to the start gear position due to misoperation or other reasons, the controller can judge the state of the prime mover, and the controller does not execute the operation instructions sent by the rotary button. After the prime mover is started, the knob switch 1 will return to the idle gear position. During the driving process of the engineering vehicle, the operator can switch between the idle gear position and multiple speed adjustment gear positions by operating the knob switch 1 to control the prime mover to perform the gear shifting operation.

[0041] In this embodiment, preferably, a reset device is provided in the knob switch 1. When the operator rotates the knob switch 1 to the left to the start gear position and releases the knob switch 1 after the prime mover is started, the knob switch 1 will rebound from the start gear position to the idle gear position under the action of the reset device, so that the prime mover is in the idle gear; thereby ensuring that the prime mover is in the idle gear position after each start, avoiding the prime mover having an excessively high speed right after the start, thereby causing serious damage to the prime mover.

[0042] It should be noted that the reset device can be a structure having, for example, a coiled spring sheet, which is wound around the inner wall of the knob switch 1, one end of which is connected to the knob switch 1, and the other end is fixedly arranged at a position corresponding to the idle gear in the knob switch 1 and does not rotate with the rotation of the knob switch 1; when the knob switch 1 is rotated to the idle gear, the coiled spring sheet is in its original position; when the knob switch 1 is rotated to the start gear, the coiled spring sheet is in a curled state and has a tendency to return to its original position, so when the operator rotates the knob switch 1 to the left to the start gear and the prime mover is started, the operator releases the knob switch 1, and the knob switch 1 will rebound from the start gear to the idle gear under the action of the reset device. In addition, the reset device can also be other structures that can achieve the reset of the knob switch 1, which will not be given one by one here.

[0043] In this embodiment, preferably, Figure 1 As shown, the control key also includes a gear ring 8, which is annular and is arranged between the knob switch 1 and the push switch 2; a plurality of gear marks are arranged on the gear ring 8, and the plurality of gear marks correspond to the start gear, the idle gear and the plurality of speed adjustment gears of the knob switch 1 one by one; Figure 1As shown, the gear position mark includes a start mark 3, which corresponds to the start gear position of the prime mover. The gear ring 8 is marked with numbers 1 to 6 in the clockwise direction. Number 1 is an idle gear mark 4, which corresponds to the idle gear position. Numbers 2 to 6 are speed control gear marks 5, which correspond to multiple speed control gear positions. A position indicator 6 is set on the knob switch 1. When the push switch 2 is engaged in the second working position, the status indicator 7 of the push switch 2 and the status indicator 7 of the knob switch 1 will be lit at the same time; when the knob switch 1 is rotated, the position indicator 6 rotates accordingly. When the knob switch 1 is rotated to a different working gear position, the position indicator 6 on the knob switch 1 will indicate on the gear mark corresponding to the working gear position, so as to facilitate the operator to judge and identify the position of the working gear position where the knob switch 1 is located.

[0044] In this embodiment, preferably, a plurality of protrusions are provided on the side wall of the knob switch 1 , and the plurality of protrusions are distributed on the side wall of the knob switch 1 at intervals along the circumference of the knob switch 1 , thereby making it more convenient for the operator to turn the knob switch 1 .

[0045] In summary, the control key of the present application integrates a push button switch 2 for controlling the power on and off of the prime mover and a knob switch 1 for starting the prime mover and realizing gear adjustment. It is not only small in size and occupies less installation space, thus saving space in the cab of the engineering vehicle; it is also fully functional and safe and convenient to operate.

[0046] The present application also provides a prime mover control method, such as Figure 2 As shown, the following steps are included:

[0047] First, the operator presses the key switch downward to engage the key switch in the second working position and maintain it in the second working position, the state indicator light of the key switch and the position indicator light of the knob switch will be lit, and the prime mover will be powered on at the same time;

[0048] Next, rotate the knob switch counterclockwise to the start gear position. When the knob switch is rotated to the start position, the position indicator light on the knob switch will indicate the position of the start mark on the gear ring, and the controller controls the prime mover to ignite and start;

[0049] Next, release the rotary switch, and the rotary switch will automatically rebound to the idle gear position under the action of the reset device, and the position indicator light will indicate the number 1 on the gear circle corresponding to the idle gear position; it should be noted that when the prime mover is started, the controller no longer executes the command of rotating the rotary switch from the idle gear position to the start gear position;

[0050] Next, the knob switch is rotated to switch between multiple speed control gears, so that the controller controls the prime mover to perform the gear shifting operation of different gears, and the working gear position of the knob switch can be judged by the position indicator light on the knob switch;

[0051] Next, press the key switch again to return the key switch from the second working position to the first working position, and the prime mover will be powered off and shut down.

[0052] Therefore, when the operator operates the engineering vehicle, he only needs to operate the control key, that is, press the button switch and rotate the knob switch to realize the power on and off, start and shift operations of the prime mover, which is simple and convenient to operate.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
