Detailed implementation mode

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. The present invention will be further described below in conjunction with the embodiments.

[0039] Please refer to Figures 1-5 , in an embodiment of the present application, a labor - saving drilling machine for punching holes in catenary tunnels includes a body 1, a drill bit 3, a speed - regulating disk 8, and a power element. The power element is arranged on the body 1. The drill bit 3 is movably arranged on the body 1 and is connected to the output end of the power element. The speed - regulating disk 8 is movably arranged on the body 1 and is electrically connected to the power element. It further includes:

[0040] Shoulder rest 6, arranged on the body 1;

[0041] Grips 7, two in number and both arranged on the body 1, and one of the grips 7 is connected to the speed - regulating disk 8;

[0042] Adsorption modules, several groups in number and all arranged on the body 1, used to adsorb and fix the drilling machine to the processing plane. The adsorption module at least includes a suction cup 4, and the suction cup 4 is arranged on the body 1;

[0043] Driving system, movably arranged on the body 1 and connected to the output end of the power element. When the power element works, the adsorption module can be controlled to work synchronously through the driving system; among them

[0044] The driving system includes:

[0045] Driving module 9, connected to the output end of the power element, used to adjust the air pressure between the suction cup 4 and the processing plane; and

[0046] Transfer module 10, arranged on the body 1, used to connect the driving module 9 and the suction cup 4.

[0047] It should be specifically noted that the power element can be a stepper motor 2 or a servo motor. In this embodiment, the power element is preferably the stepper motor 2. The stepper motor 2 is arranged on the body 1, and the output end of the stepper motor 2 is connected to the drill bit 3 and the drive module 9.

[0048] In a specific case of this embodiment, the adsorption module further includes a connecting pipe 5. The connecting pipe 5 is movably arranged on the body 1 and the two are elastically connected. Moreover, the connecting pipe 5 includes a main pipe 51 and a sub-pipe 52. The main pipe 51 is connected to the suction cup 4. The main pipe 51 and the sub-pipe 52 are connected by threads, and the sub-pipe 52 is communicated with the drive module 9 through a transfer module 10.

[0049] In another specific case of this embodiment, the drive module 9 includes:

[0050] A drive box 91, which is movably arranged on the body 1 and connected to the output end of the power element;

[0051] A first transmission box 92, which is arranged in the drive box 91. A first connection groove 94 for communicating the first transmission box 92 with the transfer module 10 is provided in the drive box 91;

[0052] A first piston 93, which is movably arranged in the first transmission box 92; and

[0053] A counterweight seat 97, which is movably arranged in the drive box 91 and elastically connected to the drive box 91. The counterweight seat 97 and the first piston 93 are connected by a connecting rod 99.

[0054] In actual application, the staff holds the handle 7 with both hands, and the shoulder position fits with the shoulder rest 6. By aligning the drill bit 3 with the processing surface and fitting the suction cup 4 with the processing surface, the hand in contact with the handle 7 on the speed control disc 8 is rotated to drive the speed control disc 8 to rotate, so that the stepping motor 2 drives the drill bit 3 to rotate for drilling work. While the stepping motor 2 drives the drill bit 3 to rotate, it also drives the drive box 91 to rotate. Under the action of centrifugal force, the weight seat 97 in the drive box 91 moves away from the first transmission box 92. During this process, the first piston 93 moves in the first transmission box 92 to extract the gas between the suction cup 4 and the processing surface along the connecting pipe 5, so that when drilling work is carried out, the whole device is fixedly attached to the processing surface to limit the position of the device in the vertical direction. It can not only perform drilling work accurately, but also reduce the human body's support work for the whole device, avoid the fatigue of the staff caused by holding with both hands for a long time, and the staff can realize the feed work of the drill bit 3 through the contact force between the shoulder and the shoulder rest 6. And when the human body rotates the speed control disc 8 to increase the rotation speed of the stepping motor 2, at this time, the moving distance of the weight seat 97 driving the first piston 93 increases, and the air pressure value between the suction cup 4 and the processing surface is further reduced. Furthermore, under the vibration action caused by the high-intensity work of the stepping motor 2, the whole device can still be stably fixed to the processing surface, further improving the adsorption effect. By rotating the main pipe 51, under the action of the threaded fit between the main pipe 51 and the auxiliary pipe 52, the stepped processing surface with unevenness can be processed.

[0055] Please refer to Figures 1-5 , as another preferred embodiment of the present application, the transfer module 10 includes a transfer box 101 and a first transfer cavity 102. The transfer box 101 is arranged on the power element and is slidably matched with the drive box 91. The first transfer cavity 102 is arranged in the transfer box 101 and is communicated with the first connection groove 94, and the first transfer cavity 102 is communicated with the connecting pipe 5.

[0056] Exemplarily in this embodiment, the handle 7 includes:

[0057] The handle body 71, two handle bodies 71 are respectively arranged on the machine body 1 and the speed control disc 8, and a cavity 72 communicated with the drive module 9 is arranged in the handle body 71; and

[0058] The buffer sacs 74, the number of which is several, several grooves 73 are arranged on the handle body 71, and the buffer sacs 74 are arranged in the grooves 73 and are communicated with the cavity 72;

[0059] The drive module 9 further includes an inflation unit, the inflation unit is arranged in the drive box 91 and is connected with the weight seat 97, and the weight seat 97 can inflate the cavity 72 through the inflation unit during operation.

[0060] It should be noted that the inflation unit includes a second transmission case 95, a second piston 98, and a second connection groove 96;

[0061] The second transmission case 95 is arranged in the drive case 91. The second piston 98 is movably arranged in the second transmission case 95 and is connected to the connecting rod 99. The second connection groove 96 is arranged in the drive case 91 and is communicated with the second transmission case 95. A second transfer cavity 103 communicated with the second connection groove 96 is arranged in the transfer case 101, and the second transfer cavity 103 is communicated with the cavity 72.

[0062] In addition, an airbag 11 is further arranged in the groove 73 formed on the shoulder rest 6, and the airbag 11 is also communicated with the second transfer cavity 103.

[0063] When the counterweight seat 97 moves away from the first transmission case 92 under the action of centrifugal force, the counterweight seat 97 drives the second piston 98 to move in the second transmission case 95, and the gas in the second transmission case 95 is respectively input into the airbag 11 and the cavity 72 along the second connection groove 96 and the second transmission cavity. The gas entering the cavity 72 is filled into the buffer bag 74, so that the volume of the buffer bag 74 expands, thereby avoiding direct contact between the human body and the handle body 71 or the shoulder rest 6, reducing the vibration impact force on the human body during the drilling work of the stepping motor 2 and the electric drill bit 3, effectively protecting the staff. And as the rotation speed of the stepping motor 2 is faster, the vibration intensity of the stepping motor 2 is greater, so that the centrifugal force received by the counterweight seat 97 increases and the moving distance increases. Furthermore, the expansion volumes of the airbag 11 and the buffer bag 74 change positively with the actual rotation speed of the stepping motor 2, thereby providing the best buffer protection for the staff.

[0064] The working principle of this application:

[0065] The operator holds the handle 7 with both hands, and the shoulder position fits with the shoulder rest 6. By aligning the drill bit 3 with the processing surface and fitting the suction cup 4 with the processing surface, the operator rotates the speed control disc 8 by the hand in contact with the handle 7 on the speed control disc 8, driving the speed control disc 8 to rotate, so that the stepping motor 2 drives the drill bit 3 to rotate for drilling work. While the stepping motor 2 drives the drill bit 3 to rotate, it also drives the drive box 91 to rotate. Under the action of centrifugal force, the counterweight seat 97 in the drive box 91 moves away from the first transmission box 92. During this process, the first piston 93 moves in the first transmission box 92 to extract the gas between the suction cup 4 and the processing surface along the connecting pipe 5, so that when drilling work is carried out, the whole device fits and fixes with the processing surface to limit the position of the device in the vertical direction. It can not only perform drilling work accurately, but also reduce the work of the human body to support the whole device, avoiding the fatigue of the operator caused by holding the device with both hands for a long time. And the operator can realize the feed work of the drill bit 3 through the contact force between the shoulder and the shoulder rest 6. When the operator rotates the speed control disc 8 to increase the rotation speed of the stepping motor 2, at this time, the moving distance of the counterweight seat 97 driving the first piston 93 increases, and the air pressure value between the suction cup 4 and the processing surface further decreases. Thus, under the vibration action caused by the high-intensity work of the stepping motor 2, the whole device can still be stably fixed with the processing surface, further improving the adsorption effect. And when the counterweight seat 97 moves away from the first transmission box 92 under the action of centrifugal force, the counterweight seat 97 drives the second piston 98 to move in the second transmission box 95, and the gas in the second transmission box 95 is respectively input into the airbag 11 and the cavity 72 along the second connecting groove 96 and the second transmission cavity. The gas entering the cavity 72 fills into the buffer bag 74, making the volume of the buffer bag 74 expand, so as to avoid direct contact between the human body and the handle body 71 or the shoulder rest 6, reducing the vibration impact force on the human body when the stepping motor 2 drives the drill bit 3 to perform drilling work, effectively providing protection for the operator. And as the rotation speed of the stepping motor 2 is faster, the vibration intensity of the stepping motor 2 is greater, resulting in the situation that the centrifugal force received by the counterweight seat 97 increases and the moving distance increases. Thus, the expansion volumes of the airbag 11 and the buffer bag 74 change positively with the actual rotation speed of the stepping motor 2, further providing the best buffer protection for the operator.

[0066] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.

[0067] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
