[0042] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will make further detailed description to the utility model embodiments combined with the drawings. However, example embodiments can be implemented in various forms, and should not be understood as being limited to the embodiments set forth herein. The same reference signs in the drawings represent the same or similar structures, so repeated description thereof will be omitted. The words expressing position and direction described in the utility model embodiments are explained taking the drawings as an example, but changes can also be made as needed, and the changes made are included in the protection scope of the utility model. The drawings of the utility model embodiments are only used to show the relative position relationship and do not represent the real proportion.

[0043] It should be noted that specific details are set forth in the following description in order to provide an understanding of the utility model. However, the utility model embodiments can be implemented in various ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the utility model embodiments. Therefore, the utility model is not limited by the specific embodiments disclosed below.

[0044] In the construction process of a building, the need to punch holes in the ceiling or wall of the building often arises to install hangers, lamps or pipelines, etc. through the holes. For example, in a data center room, the installation of fire and weak cable laying pipes, wire rack hangers, heating and ventilation pipe hangers, etc. requires screw holes to be fixed. At present, punching with a punching telescopic support and manual punching are two common punching methods. The punching telescopic support can meet the punching needs of ceilings of different heights by being raised or lowered, but the punching telescopic support has problems such as difficulty in aligning the hole position and deviation in punching after being raised, so the punching precision is relatively low; manual punching requires the operator to use a ladder or scaffold to work at height, which is low in efficiency and relatively high in cost, and also has certain safety hazards.

[0045] Therefore, the utility model embodiments provide a punching device which can not only meet the punching needs of different heights, but also adjust the punching position in multiple directions, thereby realizing high-precision and high-efficiency punching. The utility model embodiments will be described in detail below combined with the drawings.

[0046] Figure 1A structure schematic diagram of the perforating device 1000 is provided for the embodiments of the present application. Reference Figure 1 As shown in the embodiments of the present application, the perforating device 1000 comprises a telescopic arm 100 and a main body 200. The telescopic arm 100 comprises an extending end 100a, and the telescopic arm 100 changes its height by controlling the extending end 100a to extend or retract. The main body 200 is a core component for realizing perforation, and the main body 200 is arranged at the extending end 100a of the telescopic arm 100, so that the height of the main body 200 can be adjusted by the telescopic arm 100, and the main body 200 can meet the perforation requirements of different heights.

[0047] In an embodiment, the telescopic arm 100 comprises multiple sections of arms, and the multiple sections of arms comprise one section of fixed arms and at least one section of adjusting arms, the at least one section of adjusting arms are sequentially sleeved on the inner side of the fixed arms, and each section of adjusting arms can be lifted relative to the fixed arms. For example, the telescopic arm 100 comprises four sections of arms, which are respectively a first arm 110, a second arm 120, a third arm 130 and a fourth arm 140. The first arm 110 is a fixed arm, and the second arm 120, the third arm 130 and the fourth arm 140 are adjusting arms. The second arm 120 is sleeved on the inner side of the first arm 110, and the second arm 120 is in sliding connection with the first arm 110, so that the second arm 120 can extend or retract relative to the first arm 110. The third arm 130 is sleeved on the inner side of the second arm 120, and the third arm 130 is in sliding connection with the second arm 120, so that the third arm 130 can extend or retract relative to the second arm 120. The fourth arm 140 is sleeved on the inner side of the third arm 130, and the fourth arm 140 is in sliding connection with the third arm 130, so that the fourth arm 140 can extend or retract relative to the third arm 130. The extending end 100a of the fourth arm 140 is the extending end 100a of the entire telescopic arm 100.

[0048] In the embodiment, the perforating device 1000 further comprises a first motor, which is in transmission connection with the telescopic arm 100 to drive the telescopic arms of the telescopic arm 100 to extend or retract. Exemplarily, the first motor is arranged in one-to-one correspondence with the adjusting arms, and each first motor is used to drive the corresponding adjusting arm to extend or retract. In this way, each adjusting arm can be independently telescoped, and each adjusting arm can be kept in a fully retracted state, or kept in a fully extended state, or kept in a partially extended state, so that the height adjustment of the telescopic arm 100 is more flexible, and the perforation feasibility of the perforating device 1000 for different heights is improved.

[0049] It is easy to understand that the telescopic arm 100 has its minimum height when the second arm 120, the third arm 130, and the fourth arm 140 are all fully retracted, and the telescopic arm 100 has its maximum height when the second arm 120, the third arm 130, and the fourth arm 140 are all fully extended. For example, by adjusting the height of the telescopic arm 100, the drilling device 1000 can achieve drilling heights from 2.6 meters to 6.2 meters, which can meet the drilling needs of most building interiors.

[0050] In this embodiment of the invention, the punching device 1000 further includes a movable base 300. The movable base 300 can be used to support the telescopic arm 100 and the main body 200, enabling the punching device 1000 to be movable and improving its ease of use. For example, the movable base 300 can be a flatbed cart. The telescopic arm 100 includes a fixed end 100b, which is disposed opposite to the extended end 100a. For example, the fixed end 100b is the end of the fixed arm away from the extended end 100a, and the telescopic arm 100 can be fixed to the movable base 300 through the fixed end 100b.

[0051] The mobile base 300 includes a base body 310, telescopic legs 320, and wheels 330. There may be one or more telescopic legs 320, which are located on the side of the base body 310 facing away from the telescopic arm 100. The telescopic legs 320 have a retracted state and an extended state. In the retracted state, the telescopic legs 320 are hidden on the side of the base body 310 facing away from the telescopic arm 100. In the extended state, the telescopic legs 320 extend to the outside of the base body 310. There are multiple wheels 330; some wheels 330 are mounted on the side of the base body 310 facing away from the telescopic arm 100, and other wheels 330 are mounted on each of the telescopic legs 320.

[0052] In one embodiment, the movable base 300 further includes a push rod 340, which is fixed to the base body 310. The operator can move the drilling device 1000 by pushing the push rod 340, thereby improving the ease of use of the drilling device 1000.

[0053] When the drilling device 1000 is not in use or during movement, the telescopic support leg 320 is in a retracted state to reduce the area occupied by the drilling device 1000 when not in use, or to improve the ease of movement of the drilling device 1000. During use, the telescopic support leg 320 is in an extended state to provide stable support for the base body 310, improving the reliability and safety of the drilling device 1000. Furthermore, in this embodiment, the telescopic support leg 320 can be controlled by a motor to extend and retract, further enhancing convenience.

[0054] For example, the movable base 300 includes four telescopic legs 320 and eight wheels 330. The four telescopic legs 320 are paired, and the two pairs of telescopic legs 320 can extend outward from opposite sides of the base body 310 to balance the force on the drilling device 1000 and improve its stability. Four of the eight wheels 330 are mounted at the four corners of the base body 310, and the other four wheels are mounted on the four telescopic legs 320. In addition, two of the eight wheels 330 are directional wheels, and the remaining six wheels 330 are omnidirectional wheels. For example, the wheels 330 mounted at the two corners of the base body 310 away from the push rod 340 are directional wheels. This improves the directional controllability when moving the drilling device 1000 and also requires less effort.

[0055] Figure 2 This is a schematic diagram of a drilling device 1000 provided in an embodiment of the present utility model. (Reference) Figure 2 As shown, in this embodiment of the present invention, the main body 200 includes a first support arm 210, a second support arm 220, a third support arm 230, and an electric drill 240. The first support arm 210 is fixed to the extended end 100a of the telescopic arm 100 and is provided with a first guide rail 211. The second support arm 220 is slidably mounted on the first guide rail 211 and is provided with a second guide rail 221. The third support arm 230 is slidably mounted on the second guide rail 221 and is provided with a third guide rail 231. The electric drill 240 is slidably mounted on the third guide rail 231. The telescopic direction of the telescopic arm 100, the extension direction of the first guide rail 211, and the extension direction of the second guide rail 221 intersect each other. Exemplarily, the telescopic direction of the telescopic arm 100, the extension direction of the first guide rail 211, and the extension direction of the second guide rail 221 can be perpendicular to each other.

[0056] The specific structure of the first guide rail 211, the second guide rail 221, and the third guide rail 231 is not limited. For example, they can be in the form of a groove, a slide bar, or a slide plate. Correspondingly, the sliding connection structure between the second support arm 220, the third support arm 230, and the electric drill 240 and the corresponding guide rail is also not limited, as long as the second support arm 220, the third support arm 230, and the electric drill 240 can be reliably slidably installed on the corresponding guide rail.

[0057] The extension directions of the first guide rail 211, the second guide rail 221 and the third guide rail 231 are respectively defined as x, y and z directions. The second support arm 220 slides on the first guide rail 211, and can drive the third support arm 230 and the electric drill 240 to move in the x direction. The third support arm 230 slides on the second guide rail 221, and can drive the electric drill 240 to move in the y direction. The electric drill 240 slides on the third guide rail 231, and can move in the z direction. In combination with the extension and contraction of the telescopic arm 100, the electric drill 240 can move in at least three directions, thereby effectively improving the flexibility of adjusting the drilling position of the electric drill 240, reducing the difficulty of hole alignment, and thus helping the drilling device 1000 to realize high-precision and high-efficiency drilling.

[0058] In some embodiments, the main body 200 further comprises a second motor 250, a third motor 260 and a fourth motor 270. The second motor 250 is arranged on the first support arm 210, for example, on one end of the first support arm 210. The second motor 250 is in transmission connection with the second support arm 220, and can be used to drive the second support arm 220 to slide reciprocally along the first guide rail 211. The third motor 260 is arranged on the second support arm 220, for example, on one end of the second support arm 220. The third motor 260 is in transmission connection with the third support arm 230, and can be used to drive the third support arm 230 to slide reciprocally along the second guide rail 221. The fourth motor 270 is arranged on the third support arm 230, and is in transmission connection with the electric drill 240. The fourth motor 270 can be used to drive the electric drill 240 to slide reciprocally along the third guide rail 231. The motor is used to drive the support arm and the electric drill 240 to slide, which not only facilitates the adjustment of the position of the electric drill 240, but also improves the adjustment accuracy of the position of the electric drill 240, thereby helping to improve the drilling position accuracy of the drilling device 1000.

[0059] In the embodiment, the drill bit 241 of the electric drill 240 can be replaced according to the size requirement of drilling. For example, the electric drill 240 can replace any drill bit 241 with a diameter of 6mm-25mm.

[0060] Figure 3 Another structural schematic view of the drilling device 1000 provided by the embodiment of the utility model is provided. Referring to Figure 2 and Figure 3As shown in the embodiment of the utility model, the main body 200 includes the first support 280, the first support 280 is slidably arranged on the second guide rail 221, and the third supporting arm 230 is rotatably arranged on the first support 280. In a specific implementation, the first support 280 includes the first sliding frame 281 and the support plate 282, the first sliding frame 281 is slidably arranged on the second guide rail 221, and the support plate 282 is fixed on the first sliding frame 281. The third supporting arm 230 is rotatably arranged on the support plate 282. When the third supporting arm 230 rotates relative to the support plate 282, the electric drill 240 also rotates synchronously, so that the drill bit 241 of the electric drill 240 also changes accordingly, so that the electric drill 240 can realize punching at different angles, thereby effectively expanding the application scenarios of the punching device 1000.

[0061] The rotation axis direction of the third supporting arm 230 can be designed according to requirements, for example, in one implementation, the rotation axis direction of the third supporting arm 230 is the same as the extension direction of the first supporting arm 210; in another implementation, the rotation axis direction of the third supporting arm 230 is the same as the extension direction of the second supporting arm 220. For example Figure 2 And Figure 3 An example in which the rotation axis direction of the third supporting arm 230 is the same as the extension direction of the first supporting arm 210 is shown in the figure.

[0062] In one embodiment, the support plate 282 can be a semicircular structure. One side surface of the support plate 282 is fixedly connected with the first sliding frame 281, and the other side surface of the support plate 282 is used for mounting the third supporting arm 230. Exemplarily, the third supporting arm 230 can be rotatably connected with the support plate 282 through a rotating shaft.

The side plate 2332 of the dust catcher 233 is provided with a second opening 23321, and the second opening 23321 and the first opening 23311 are mutually penetrated. Before punching, the dust catcher 233 slides away from the end of the fourth guide rail 2341 close to the electric drill 240, so as to avoid blocking the punching position. After determining the punching position, first, the height of the telescopic arm 100, the second support arm 220, the third support arm 230 and the sliding position of the electric drill 240 are adjusted, so that the drill bit 241 of the electric drill 240 is aligned with the position to be punched, and then the dust catcher 233 is adjusted to slide in the direction close to the electric drill 240. In the process of sliding the dust catcher 233, the drill bit 241 of the electric drill 240 gradually passes through the second opening 23321 and enters the first opening 23311, and after the dust catcher 233 slides to the position where the drill bit 241 completely enters the first opening 23311, the punching can be started. It can be seen that the dust catcher 233 slides to the punching position after the drill bit 241 of the electric drill 240 is aligned with the position to be punched, and this punching method can not only avoid the difficulty of hole alignment caused by the dust catcher 233, but also reliably collect dust.
