[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] Example:

[0025] like Figure 1-Figure 4 As shown, a beam bottom plate punching device with adjustable punching depth comprises a support tube 1 and a connecting rod 2 which is telescopically arranged in the telescopic tube, and a puncher 3 is provided at the end of the connecting rod 2;

[0026] The connecting rod 2 is driven by the transmission assembly to move axially along the telescopic tube.

[0027] The support tube 1 is a square tube, and the cross section of the connecting rod 2 is a rectangle.

[0028] The transmission assembly includes a transmission chain 4 and a transmission sprocket 5, wherein the transmission chain 4 is axially arranged along the connecting rod 2 (the transmission chain 4 is in a stretched state), the transmission sprocket 5 is rotatably connected to the support tube 1, and the transmission sprocket 5 is connected to a wrench 6 that drives the transmission sprocket 5 to rotate;

[0029] The support tube 1 is provided with a strip hole 7 , and the transmission sprocket 5 passes through the strip hole 7 and engages with the transmission chain 4 .

[0030] The support tube 1 is provided with two connecting ribs 8, and the connecting ribs 8 are provided with through holes 9. The transmission sprocket 5 is arranged between the two connecting ribs 8. The transmission sprocket 5 is coaxially fixed with a bolt 10. The transmission sprocket 5 is connected to the two connecting ribs 8 via the bolt 10 and the through hole 9, and the wrench 6 is fixedly connected to the bolt 10 or the transmission sprocket 5.

[0031] The transmission chain 4 is fixed to the connecting rod 2 by welding.

[0032] Working principle: When it is necessary to drill a hole at a high place (ceiling / roof), first align the square support tube 1 with the position to be drilled, and make the bottom of the support tube 1 contact the ground, so that the support tube 1 is in a vertical state.

[0033] Then, the wrench 6 is manually pulled downward, and the wrench 6 drives the transmission sprocket 5 to rotate. In this process, the connecting rod 2 moves upward under the action of the transmission sprocket 5 and the transmission chain 4, thereby realizing the "lifting" of the punching machine 3. When the punching machine 3 is in place (the wrench 6 can be fixed by hand, or an anti-rotation device (such as a ratchet) can be set on the support tube 1 to prevent the connecting rod 2 from falling back to the support tube 1 during use), the punching machine 3 can be started to punch holes.

[0034] The utility model arranges the punching machine 3 on the retractable connecting rod 2, so that the workers can punch holes at a high place without climbing a ladder. Meanwhile, the raising process of the connecting rod 2 can be realized by simply turning the wrench 6, which is simple to operate and greatly improves the punching efficiency.

[0035] Furthermore, the connector plate is provided with a plurality of through holes 9 along its length direction. The plurality of through holes 9 are provided for replacing transmission sprockets 5 of different diameters, and transmission sprockets 5 of different diameters can control different maximum extension degrees of the connecting rod 2 (e.g., the larger the transmission sprocket 5, the longer the connecting rod 2 can be extended).

[0036] Furthermore, if Figure 3 and Figure 4 As shown, the puncher 3 is connected to the connecting rod 2 via a connecting plate 11, one end of the connecting plate 11 is hinged to the connecting rod 2 via an ear plate, a hydraulic support rod 12 is provided at the bottom of the connecting plate 11, and both ends of the hydraulic support rod 12 are hinged to the bottom of the connecting plate 11 and the connecting rod 2 respectively.

[0037] The punching machine 3 (its body and handle) is connected to the connecting rod 2 and the connecting plate 11 respectively through a steel bundle clamp 13.

[0038] The hydraulic support rod 12 is used to support the connecting plate 11 , and the hydraulic support rod 12 can buffer the vibration generated when the puncher 3 punches holes; and the steel bundle clamp 13 can facilitate the disassembly and assembly of the puncher 3 and the connecting rod 2 .

[0039] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
