Description

Technical Field

[0001] This utility model relates to the technical field of channel steel processing equipment, specifically a channel steel drilling device for rail transit. Background Technology

[0002] In rail transit, a large amount of channel steel is used for track laying. The holes in the channel steel reduce its weight without compromising its original structural strength. Furthermore, these holes increase structural stability by reducing localized weight distribution, resulting in a more balanced overall structure. They also facilitate welding, drilling, and cutting processes, greatly improving construction efficiency. However, during the drilling process, a large amount of debris remains on the surface of the channel steel. If this debris is not cleaned promptly, it accumulates at the drilling sites, affecting the assembly efficiency of the channel steel. Since the channel steel is long and narrow, drilling is typically done manually along its length, followed by cleaning the surrounding debris, which is labor-intensive. Therefore, this solution provides a channel steel drilling device for rail transit. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling device for channel steel in rail transit, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for channel steel in rail transit, comprising a machine base, a first frame, and a second frame.

A first sliding groove is formed on the surface of the first frame, and an electric lifting machine is slidably installed on the first sliding groove via a slider. A drilling machine is connected to the bottom of the electric lifting machine via a lifting rod, and a drill bit is located at the bottom of the drilling machine.

[0005] Hollow rectangular bases are provided on both the left and right edges of the machine base. The bottom left and right sides of the second frame are inserted into the rectangular bases.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a drilling device for channel steel for rail transit, including a machine base 1, a first frame 2 and a second frame 3. The first frame 2 is located at the top center of the machine base 1, and the second frame 3 is located on one side of the first frame 2. A telescopic cylinder 4 is located at the end of the machine base 1, and a push plate 5 is connected to one end of the telescopic cylinder 4. First electric telescopic rods 6 are installed on the left and right outer sides of the first frame 2 through support seats. The end of the first electric telescopic rod 6 passes through the first frame 2 and is connected to a limit plate 7. A second electric telescopic rod 8 is installed on the top side of the first frame 2. A first sliding groove 9 is opened on the surface of the first frame 2. An electric lifting machine 10 is slidably installed on the first sliding groove 9 through a slider. A drilling machine 12 is connected to the bottom of the electric lifting machine 10 through a lifting rod 11. A drill bit 13 is located at the bottom of the drilling machine 12.

[0018] Hollow rectangular bases 14 are provided on both the left and right edges of the machine base 1. The bottom of the left and right sides of the second frame 3 are inserted into the rectangular bases 14. A second sliding groove 15 is opened on the surface of the second frame 3. A lead screw drive motor 16 is fixedly installed on one side of the top of the second frame 3. A lead screw 17 along the transverse axis of the second frame 3 is installed at one end of the lead screw drive motor 16. A lead screw nut slider 18 is slidably connected to the lead screw 17. A spring rod 19 is connected to the bottom of the lead screw nut slider 18. A brush plate 20 is installed at the bottom end of the spring rod 19.

[0019] An industrial control computer 21 is installed on one side of the edge of the machine base 1. The industrial control computer 21 is electrically connected to the telescopic cylinder 4, the first electric telescopic rod 6, the second electric telescopic rod 8, the electric lift 10, and the lead screw drive motor 16 through wires built into the machine base 1. The industrial control computer 21 controls the operation of each drive component in this structure.

[0020] The telescopic shaft end of the second electric telescopic rod 8 is fixed to the side of the electric lift 10. The electric lift 10 is driven by the second electric telescopic rod 8 to move laterally along the first slide groove 9 on the surface of the first frame 2. The electric lift 10 slides laterally in the left and right directions on the first slide groove 9 through the slider. The bottom end of the electric lift 10 passes through the slider and connects to the lifting rod 11. The electric lift 10 can move laterally in the left and right directions at the first slide groove 9 through the telescopic shaft driven by the second electric telescopic rod 8. This is used to adjust the left and right position of the drill bit 13 on the upper surface of the channel steel, so as to facilitate drilling operations at different positions on the surface of the channel steel.

[0021] The first electric telescopic rod 6 drives the limiting plate 7 to move toward the center of the machine platform 1. The inner side of the limiting plate 7 facing the machine platform 1 is corrugated, and the limiting plate 7 is a rubber plate; this facilitates clamping, limiting and fixing of the channel steel on the left and right sides of the channel steel.

[0022] The specific drilling process is as follows:

[0023] During the drilling process of the channel steel, the channel steel is first manually moved and placed in the center of the machine platform 1 until the end of the channel steel contacts the push plate 5. Then, the two first electric telescopic rods 6 on both sides of the first frame 2 are controlled by the industrial control computer 21 to push the limiting plate 7 to clamp the channel steel in the center of the machine platform 1. The limiting plate 7 is a rubber plate with a corrugated inner side to increase the friction between the limiting plate 7 and the side of the channel steel, which is used to clamp and fix the channel steel.

[0024] Next, the second electric telescopic rod 8 on the first frame 2 is controlled by the industrial control computer 21 to drive the electric lifting machine 10 to move laterally along the first slide 9. This is used to adjust the position of the drill bit 13 on the channel steel, so that after the channel steel is fixed, the drill bit 13 can be aligned with the center of the channel steel for drilling.

[0025] The electric lifting platform 10 operates, driving the drilling machine 12 to move downward. The drilling machine 12 has a drive motor that drives the drill bit 13 to rotate, allowing the drill bit 13 to drill holes in the surface of the channel steel during the downward rotation process. After the drilling is completed, the first electric telescopic rods 6 on both sides of the first frame 2 drive the limit plate 7 to reset and pull back, releasing the clamping and fixing on both sides of the channel steel.

[0026] Next, the telescopic cylinder 4 at the end of the machine base 1 is controlled by the industrial control computer 21 to operate, and the push plate 5 pushes the channel steel to the front end of the machine base 1. Before the pushing process, the lead screw drive motor 16 on the second frame 3 is controlled by the industrial control computer 21 to operate, driving the lead screw 17 to rotate. The lead screw drive motor 16 is a forward and reverse motor, used to drive the lead screw 17 to rotate in different directions. Several balls in the internal circulation channel of the lead screw nut slider 18 are engaged with the threads on the outer surface of the lead screw 17, allowing the lead screw nut slider 18 to move laterally along the lead screw 17, so that... Both the bottom spring rod 19 and the brush plate 20 move laterally. The brush plate 20 is subjected to the elastic force of the spring rod 19, so that the brush plate 20 is normally and tightly attached to the upper surface of the channel steel. The brush plate 20 can sweep and clean the debris near the drilled holes on the surface of the channel steel by moving back and forth. This allows the debris at different drilled holes to be cleaned quickly during the pushing process of the drilled channel steel, saving the manual labor of drilling along the length of the channel steel and cleaning the debris around the drilled holes. This provides convenience for the chip removal of the drilling process of the channel steel.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
