DETAILED DESCRIPTION

The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

Embodiment 1

As shown in Figures 1 to 5, a mountain walking support auxiliary mechanism of a rotary drilling rig includes a chassis 2, a crawler mechanism 1 and a rotary drilling mechanism 3. A lifting mechanism 4 is fixedly arranged at the front end of the chassis 2, and an unfolding mechanism 5 is arranged on the outer side of the lifting mechanism 4; the unfolding mechanism 5 includes a support plate 51, an unfolding component 52 arranged on the support plate 51, and a first unfolding plate 53 and a second unfolding plate 54 connected to the unfolding component 52 and arranged opposite to each other; a plurality of groups of auxiliary rollers 6 are arranged on the side of the first unfolding plate 53 and the second unfolding plate 54 facing the chassis 2.

Among them, by arranging the first unfolding plate 53, the second unfolding plate 54 and the auxiliary roller 6 at the front end of the chassis 2, when the rotary drilling rig moves downward on the slope, the first unfolding plate 53, the second unfolding plate 54 and the auxiliary roller 6 can be placed on the ground, which can replace the use of the rotary drilling head to provide a certain support effect for the cab to avoid the cab from overturning. At the same time, such an arrangement can prevent the rotary drilling mechanism 3 from being damaged.

Further, as shown in FIGS. 3 and 4 , the lifting mechanism 4 includes a lower fixed plate 41, an upper fixed plate 42, a support rod 43, a threaded rod 44, a lifting plate 45 and a driving unit 46. The lower fixed plate 41 is fixedly connected to the chassis 2; the upper fixed plate 42 is connected to the lower fixed plate 41 through a plurality of groups of support rods 43; the threaded rod 44 is rotatably arranged between the lower fixed plate 41 and the upper fixed plate 42; the lifting plate 45 is transmission-arranged with the threaded rod 44 and is slidably connected with the plurality of groups of support rods 43; the driving unit 46 is transmission-arranged with the threaded rod 44;

The support plate 51 is fixedly connected to the lifting plate 45 via a connecting plate 47 .

Wherein, by setting the lifting mechanism 4 and the unfolding mechanism 5, the unfolding mechanism 5 can be controlled to be away from or close to the ground.

In detail, when it is necessary to control the first unfolding plate 53 and the second unfolding plate 54 to be close to the ground, the driving unit 46 is controlled to work, and the driving unit 46 will drive the threaded rod 44 to rotate. After the threaded rod 44 rotates, it will drive the lifting plate 45 to slide along the multiple groups of support rods 43, thereby driving the unfolding mechanism 5 to move up and down.

It should be noted that one or both of the lower fixing plate 41 and the upper fixing plate 42 need to be fixed to the chassis 2 to ensure the stability of the lifting mechanism 4 .

Further, as shown in Figure 5, the unfolding component 52 includes a telescopic unit 521, a first push plate 522, a first slider 523, a slide rail 524, a first transmission rod 525, a rotating rod 526, a second transmission rod 527, a second push plate 528 and a second slider 529. The telescopic unit 521 is arranged in two groups in parallel and fixedly arranged on the support plate 51 respectively. The output end of the telescopic unit 521 is connected to the first push plate 522; the first slider 523 is fixedly connected to the first push plate 522 and is slidably arranged on the slide rail 524, and the slide rail 524 is fixedly arranged on the support plate 51; the first transmission rod 525 is hinged to the middle part of the first push plate 522 and the other end is hinged to the rotating rod 526, the rotating rod 526 is rotatably arranged at the upper end center position of the support plate 51 and the other end is hinged to the second transmission rod 527; the second push plate 528 is hinged to the second transmission rod 527 and is slidably arranged on the slide rail 524 through the second slider 529.

Among them, by setting the unfolding component 52 to cooperate with the first unfolding plate 53 and the second unfolding plate 54, the first unfolding plate 53 and the second unfolding plate 54 can be controlled to unfold or retract. When the first unfolding plate 53 and the second unfolding plate 54 are retracted, the space occupied by the unfolding mechanism 5 and the first unfolding plate 53 and the second unfolding plate 54 can be reduced, which is convenient for storage.

In detail, when the first unfolding plate 53 and the second unfolding plate 54 need to be unfolded, the telescopic unit 521 is controlled to work, and the telescopic unit 521 will drive the first push plate 522 and the first slider 523 to slide on the slide rail 524. During the sliding process of the first push plate 522, the rotating rod 526 will also be driven to rotate through the first transmission rod 525. The rotating rod 526 will drive the second transmission rod 527 to move and then drive the second push plate 528 and the second slider 529 to slide on the slide rail 524. The first push plate 522 and the second push plate 528 will move in the opposite direction, thereby driving the first unfolding plate 53 and the second unfolding plate 54 away from each other.

It should be noted that the first unfolding plate 53 and the second unfolding plate 54 are placed on the support plate 51 , so the first unfolding plate 53 and the second unfolding plate 54 will not interfere with the support plate 51 when moving.

Further, as shown in FIGS. 6-7 , the first deployment plate 53 is fixedly connected to the first push plate 522 , and the second deployment plate 54 is fixedly connected to the second push plate 528 ;

The bottom of the support plate 51 is connected to a third expansion plate 56 via a plurality of buffer springs 55. Both sides of the third expansion plate 56 are provided with rounded corners. The first expansion plate 53 and the second expansion plate 54 are also provided with rounded corners on the side facing the third expansion plate 56.

The first unfolding plate 53 and the second unfolding plate 54 both include a first vertical plate portion 531 , a first horizontal plate portion 532 , a second vertical plate portion 533 and a second horizontal plate portion 534 .

Among them, by setting the first unfolding plate 53, the second unfolding plate 54 and the third unfolding plate 56, it can be achieved that when the first unfolding plate 53 and the second unfolding plate 54 are unfolded, there is no gap between the first unfolding plate 53 and the second unfolding plate 54, which can provide a better support effect for the chassis 2 and prevent dirt and debris from entering the lower end of the chassis 2 along the gap between the first unfolding plate 53 and the second unfolding plate 54.

Specifically, after the first deployment plate 53 and the second deployment plate 54 are fully deployed under the drive of the deployment assembly 52, the third deployment plate 56 is no longer supported by the first deployment plate 53 and the second deployment plate 54. Under the action of the buffer spring 55, the third deployment plate 56 pops up downward and is on the same horizontal plane as the first deployment plate 53 and the second deployment plate 54.

When the first unfolding plate 53 and the second unfolding plate 54 are retracted, since the first unfolding plate 53, the second unfolding plate 54 and the third unfolding plate 56 have rounded corners at their abutment, the third unfolding plate 56 will be squeezed and move upward again under the squeezing action of the first unfolding plate 53 and the second unfolding plate 54.

It should be noted that, since the third unfolding plate 56 does not need to be installed with the auxiliary roller 6 , the third unfolding plate 56 only needs to be provided with a set of vertical plate parts and a set of horizontal plate parts.

Further, as shown in FIGS. 8 to 10 , a cleaning mechanism 7 is provided on the side of the first unfolding plate 53 and the second unfolding plate 54 away from the chassis 2, and the cleaning mechanism 7 and the auxiliary roller 6 are arranged for transmission via a transmission mechanism 8, and the cleaning mechanism 7 includes a plurality of groups of rotating parts 71 fixedly arranged on the outside of the first vertical plate part 531, a transmission part 72 wound around the outside of the rotating part 71, and a plurality of groups of cleaning plates 73 fixedly arranged on the transmission part 72;

The transmission mechanism 8 includes a first bevel gear 81, a second bevel gear 82, a first rotating wheel 83, a second rotating wheel 84 and a transmission belt 85. The first bevel gear 81 is coaxially arranged with one group of the rotating parts 71 and is in transmission with the second bevel gear 82; the first rotating wheel 83 is coaxially arranged with the second bevel gear 82; the second rotating wheel 84 is coaxially arranged with one group of the auxiliary rollers 6 and is in transmission with the first rotating wheel 83 through the transmission belt 85;

The second vertical plate portion 533 defines a notch 5331 at a position corresponding to the transmission belt 85 .

Among them, by setting up a cleaning mechanism 7 in cooperation with the transmission mechanism 8, it can be achieved that when the first unfolding plate 53, the second unfolding plate 54 and the auxiliary roller 6 move on the ground, the cleaning mechanism 7 works synchronously and sweeps out the soil accumulated on the outside of the first unfolding plate 53 and the second unfolding plate 54, so as to avoid the accumulation of too much soil on the outside of the first unfolding plate 53 and the second unfolding plate 54, thereby affecting the normal movement of the first unfolding plate 53 and the second unfolding plate 54.

In detail, when the first unfolding plate 53 and the second unfolding plate 54 are placed on the ground and moved, the auxiliary rollers 6 will move synchronously on the ground. When one of the auxiliary rollers 6 rotates, it will drive the transmission belt 85 to move through the second rotating wheel 84. The transmission belt 85 will drive the first rotating wheel 83 to rotate and then drive the second bevel gear 82 and the first bevel gear 81 to rotate. After the first bevel gear 81 rotates, it will drive one of the rotating parts 71 to rotate. After the rotating part 71 rotates, it will drive the transmission part 72 to move on multiple groups of rotating parts 71, and then drive multiple groups of cleaning plates 73 to move on the transmission part 72 and complete the cleaning work.

It should be noted that the rotating part 71 may be, but is not limited to, a rotating wheel or a sprocket, and the transmission part 72 may be, but is not limited to, a transmission belt or a chain.

Working process:

When the rotary drilling rig moves downward on the slope, in order to improve the supporting effect of the chassis 2, the first deployment plate 53 and the second deployment plate 54 need to be deployed and placed on the ground. At this time, it is necessary to control the driving unit 46 to work first. The driving unit 46 will drive the threaded rod 44 to rotate. After the threaded rod 44 rotates, it will drive the lifting plate 45 to slide along the multiple groups of support rods 43. The lifting plate 45 will drive the deployment mechanism 5, the first deployment plate 53 and the second deployment plate 54 to descend until the first deployment plate 53 and the second deployment plate 54 are placed on the ground. Then the telescopic unit 521 is controlled to work. The telescopic unit 521 will drive the first push plate 522 and the first slider 523 to slide on the slide rail 524. The first push plate 522 slides During the process, the first transmission rod 525 will drive the rotating rod 526 to rotate, and the rotating rod 526 will drive the second transmission rod 527 to move, thereby driving the second push plate 528 and the second slider 529 to slide on the slide rail 524, and the first push plate 522 and the second push plate 528 will move in the opposite direction, thereby driving the first deployment plate 53 and the second deployment plate 54 to move away from each other. When the first deployment plate 53 and the second deployment plate 54 move away from each other to the maximum position, the third deployment plate 56 is no longer supported by the first deployment plate 53 and the second deployment plate 54. Under the action of the buffer spring 55, the third deployment plate 56 will pop up downward and be on the same horizontal plane as the first deployment plate 53 and the second deployment plate 54.

Then the rotary drilling rig can move normally along the slope. During the movement, one of the auxiliary rollers 6 will drive the transmission belt 85 to move through the second rotating wheel 84 when it rotates, and the transmission belt 85 will drive the first rotating wheel 83 to rotate and then drive the second bevel gear 82 and the first bevel gear 81 to rotate. After the first bevel gear 81 rotates, it will drive one of the rotating parts 71 to rotate. After the rotating part 71 rotates, it will drive the transmission part 72 to move on the multiple groups of rotating parts 71, and then drive the multiple groups of cleaning plates 73 to move on the transmission part 72 and complete the cleaning work.

Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
