Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to an anti-shake manhole cover drilling device. Background Technique

[0002] There are many underground pipelines in urban construction, such as sewer pipelines, underground gas pipelines, tap water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. There should be an outlet leading to the ground at regular intervals for these pipelines. The section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground. Therefore, a lid is needed to cover the manhole, which is called a manhole cover. Manhole covers are usually made of materials such as reinforced cement, metal, and reinforced plastic, and are mainly circular and square in shape. On the manhole cover, information such as the use of the underground pipeline, the maintenance unit, and the telephone number should generally be indicated. During the processing of the manhole cover, a drilling device is required to drill holes in it.

[0003] For example, a drilling device for processing ductile iron manhole covers proposed in Chinese Patent (CN219598147U) includes a support frame. A transparent box body is fixedly installed at the top of the support frame, and an adjustment mechanism is arranged inside the transparent box body; a first motor drives a drill bit to rotate for drilling the manhole cover, and the gas outside the fan is sent into the interior of the square pipe through a gas distribution pipe and a hose by starting the fan, and the gas is ejected through a first nozzle to blow up the debris generated by drilling and fall into the chip outlet. At the same time, since the first nozzle is in a V shape, it can also blow out the debris splashed inside the transparent box body during drilling. The first nozzle can be adjusted to different heights through the adjustment mechanism, which is more conducive to cleaning the debris generated during the drilling of the drill bit, so as to achieve the purpose of cleaning the debris generated by drilling, effectively preventing the debris generated by drilling from falling into the interior of the drill hole and affecting the drilling accuracy.

[0004] The above solution still has the following technical deficiencies. The above solution is not convenient for preventing the manhole cover from shaking during processing. Since the above solution only uses arc-shaped clamping plates to abut and clamp the periphery of the manhole cover, it is difficult to limit the manhole cover in the up and down directions, so it is difficult to avoid the up and down shaking of the manhole cover during processing. Based on this, an anti-shake manhole cover drilling device is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an anti-shake manhole cover drilling device, which has the advantages of being able to prevent the manhole cover from moving horizontally or shaking up and down during processing, and solves the problem that the manhole cover is prone to shaking in the up and down direction during drilling.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An anti-vibration manhole cover drilling device, including a base, a processing table is fixed on the top side of the base, an anti-vibration mechanism is provided on the processing table, four vertical rods are fixed on the top side of the base, a top plate is fixed on the top sides of the four vertical rods, a linear module is fixed on the bottom side of the top plate, a cross plate is fixed on the bottom side of the linear module, and a positioning mechanism and a drilling assembly are provided on the bottom side of the cross plate;

[0007] The anti-vibration mechanism includes two left and right mounting plates fixed on the top side of the processing table. Motors are fixed on the opposite sides of the plurality of mounting plates. A lead screw is fixed on the output shaft of the motor. A sleeve is threadedly connected to the outer surface of the lead screw. A clamping plate is fixed at the end of the sleeve away from the motor. An expansion rod is fixed on the side of the clamping plate close to the motor. A first screw is threadedly connected to the inner wall of the top side of the mounting plate. A pressing plate is rotatably connected to the bottom side of the first screw. A first handle is fixed on the top side of the first screw.

[0008] Further, the positioning mechanism includes two vertical plates fixed on the bottom side of the cross plate. A second screw is threadedly connected to the inside of the front vertical plate. A baffle is fixed on the front side of the second screw. A second handle is fixed on the rear side of the second screw. A connecting block is fixed on the outer surface of the second screw. An infrared emitter body is fixed on the bottom side of the connecting block.

[0009] Further, the drilling assembly includes a hydraulic cylinder fixed on the bottom side of the cross plate. A drill is fixed on the telescopic end of the hydraulic cylinder. A drill bit is fixed on the output shaft of the drill.

[0010] Further, the side of the expansion rod away from the clamping plate is fixed to the inside of the mounting plate. The clamping plate is an arc-shaped plate.

[0011] Further, a bearing seat is fixed on the top side of the pressing plate. The first screw can rotate in the bearing seat.

[0012] Further, a through hole is opened in the mounting plate. The lead screw can rotate in the through hole.

At the same time, it can compact the manhole cover by using a pressing plate to avoid the up-and-down shaking of the manhole cover during drilling. By arranging a positioning mechanism on the bottom side of the cross plate, it can display the part to be drilled by using the infrared rays emitted by the infrared emitter body, so as to facilitate the user to adjust the drilling part.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 5, A jitter-proof manhole cover drilling device in this embodiment includes a base 1. A processing table 2 is fixed on the top side of the base 1. A jitter-proof mechanism 300 is provided on the processing table 2. Four vertical rods 4 are fixed on the top side of the base 1. A top plate 5 is fixed on the top sides of the four vertical rods 4. A linear module 6 is fixed on the bottom side of the top plate 5. A cross plate 7 is fixed on the bottom side of the linear module 6. A positioning mechanism 800 and a drilling assembly 900 are provided on the bottom side of the cross plate 7. The drilling assembly 900 includes a hydraulic cylinder 901 fixed on the bottom side of the cross plate 7. A drill 902 is fixed on the telescopic end of the hydraulic cylinder 901. A drill bit 903 is fixed on the output shaft of the drill 902.

[0024] The jitter-proof mechanism 300 in this embodiment is used to prevent the manhole cover from moving horizontally or jittering up and down during the processing. The linear module 6 is used to adjust the drilling position. The positioning mechanism 800 is used to position and display the adjusted drilling position. The drilling assembly 900 is used to perform drilling.

[0025] It should be noted that the hydraulic cylinder 901 is used to drive the drill 902 and the drill bit 903 to move up and down. The drill 902 is used to drive the drill bit 903 to drill.

[0026] Please refer to Figures 1 to 2 , In order to prevent the manhole cover from jittering during the processing, the jitter-proof mechanism 300 in this embodiment includes two left and right mounting plates 301 fixed on the top side of the processing table 2. Motors 302 are fixed on the opposite sides of the plurality of mounting plates 301. Lead screws 303 are fixed on the output shafts of the motors 302. Through holes are opened inside the mounting plates 301. The lead screws 303 can rotate in the through holes. A sleeve 304 is threadedly connected to the outer surface of the lead screw 303. A clamping plate 305 is fixed on the end of the sleeve 304 away from the motor 302. The clamping plate 305 is an arc-shaped plate. A telescopic rod 306 is fixed on the side of the clamping plate 305 close to the motor 302. The side of the telescopic rod 306 away from the clamping plate 305 is fixed to the inner side of the mounting plate 301. A first screw 307 is threadedly connected to the top side wall of the mounting plate 301. A pressing plate 308 is rotatably connected to the bottom side of the first screw 307. A bearing seat is fixed on the top side of the pressing plate 308. The first screw 307 can rotate in the bearing seat. A first handle 309 is fixed on the top side of the first screw 307.

[0027] In the jitter-proof mechanism 300 of this embodiment, the motor 302 can drive the lead screw 303 to rotate, thereby driving the sleeve 304 and the clamping plate 305 to move. The clamping plate 305 is used to clamp the manhole cover. The pressing plate 308 is used to limit the manhole cover in the up and down directions, thereby preventing the manhole cover from jittering.

[0028] It should be noted that rubber pads are fixed on both the clamping plate 305 and the pressing plate 308. The rubber pads are used to prevent the clamping plate 305 and the pressing plate 308 from causing indentations on the manhole cover. The telescopic end of the telescopic rod 306 limits the clamping plate 305 by moving along with the clamping plate 305.

[0029] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , in order to facilitate the positioning and display of the drilling site, the positioning mechanism 800 in this embodiment includes two vertical plates 801 fixed to the bottom side of the horizontal plate 7. A second screw rod 802 is threadedly connected inside the front vertical plate 801. A rotation hole is formed inside the rear vertical plate 801. The second screw rod 802 can rotate in the rotation hole. A baffle 803 is fixed to the front side of the second screw rod 802. A second handle 804 is fixed to the rear side of the second screw rod 802. A connecting block 805 is fixed to the outer surface of the second screw rod 802. An infrared emitter body 806 is fixed to the bottom side of the connecting block 805.

[0030] In the positioning mechanism 800 of this embodiment, the infrared emitter body 806 can display the part of the manhole cover to be drilled, thereby avoiding deviation of the drilling site. The second handle 804 is used to drive the second screw rod 802 to rotate, so as to facilitate the adjustment of the angle of the infrared emitter body 806 during installation.

[0031] It should be noted that manhole covers of different thicknesses will affect the irradiation position of the infrared ray. Therefore, the angle of the infrared emitter body 806 needs to be adjusted. However, since the angle of the infrared emitter body 806 usually only needs to be slightly adjusted, the distance that the second screw rod 802 drives the infrared emitter body 806 to move back and forth is very limited and will not affect the drilling positioning. If the moving distance is too large, the linear module 6 can also be used for position adjustment.

[0032] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0033] The working principle of the above embodiment is as follows:

[0034] When it is necessary to drill the manhole cover, place the manhole cover on the processing table 2, start the motor 302, the output shaft of the motor 302 rotates to drive the lead screw 303 to rotate, the lead screw 303 drives the sleeve 304 to move, and the sleeve 304 drives the clamping plate 305 to clamp the manhole cover. Then turn off the motor 302, rotate the first handle 309, the first handle 309 drives the first screw 307 to rotate, the first screw 307 drives the pressing plate 308 to move downward, and the pressing plate 308 compresses the manhole cover. Then turn on the infrared emitter body 806, and the infrared rays generated by the infrared emitter body 806 irradiate on the manhole cover, so as to pre-display the drilling part. Then start the linear module 6, the linear module 6 drives the cross plate 7 to move, the cross plate 7 drives the positioning mechanism 800 and the drilling assembly 900 to move. When the infrared rays irradiate at the specified position, turn off the linear module 6, start the drill 902, the output shaft of the drill 902 drives the drill bit 903 to rotate, start the hydraulic cylinder 901, the hydraulic cylinder 901 drives the drill bit 903 to move downward, and the drill bit 903 drills the manhole cover. When it is necessary to adjust the irradiation angle of the infrared emitter body 806, turn the second handle 804, the second handle 804 drives the second screw 802 to rotate, and the second screw 802 drives the infrared emitter body 806 to adjust the angle.
