Description

Technical Field

[0001] The utility model relates to a drilling device, in particular to a rail drilling device applied to the field of rail drilling. Background Art

[0002] In modern railway construction, rail drilling is an indispensable project for roadbed, electrical communication and signal construction. In the maintenance and construction of railway engineering, electrical and other departments, rail drilling operations are often involved, and rail drilling devices are used during the operation.

[0003] The specification of Chinese patent CN212019470U discloses a rail drilling device. The utility model is provided with mold holes and positioning holes on the clamping plates arranged on the left and right sides of the support plate. The positioning holes are used in conjunction with the first drilled holes to ensure the accuracy between the later drilled holes and the first drilled holes.

[0004] However, the following problems may occur during use of the above-mentioned drilling device: in the above-mentioned practical application, the support plate and the clamping plate are combined in a U shape, which is sleeved on the surface of the rail, and then the dynamic pressure block is driven to move by rotating the screw, so that the dynamic pressure block squeezes and fixes the rail, but the distance between the two clamping plates is fixed. When fixing the rail, if the size of the upper end of the rail is small, there will still be a gap between the clamping plate and the rail after the drilling device is fixed to the rail. During the process of the drill bit drilling the rail, the drill bit and the rail are in hard contact, causing the drilling equipment to vibrate greatly, which may cause the drilling device to move, causing the position of the rail drilling hole to shift, thereby reducing the drilling accuracy. Utility Model Content

[0005] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that the existing drilling device cannot adapt to rails of different sizes during the process of drilling holes in rails, which may cause a gap between the fixing component and the rail, causing the drilling device to be displaced due to vibration during the drilling process, causing the drilling position to shift, thereby reducing the drilling accuracy.

[0006] In order to solve the above problems, the utility model provides a rail drilling device, including a base plate, the upper end of the base plate is fixedly connected to a positioning plate and a mounting plate from left to right in sequence, the left end of the mounting plate is fixedly connected to a fixing assembly, the left end of the mounting plate is fixedly connected to two electric telescopic rods, the left end of the electric telescopic rod is fixedly connected to an electromagnetic suction cup, a drilling groove is chiseled on the surface of the positioning plate, the left end of the mounting plate is fixedly connected to a cylinder, the left end of the cylinder is fixedly connected to a motor, the left end of the motor is fixedly installed with a drill bit, and the fixing assembly includes two fixing brackets The fixing frame on the right is fixedly connected to the positioning plate, and a receiving groove is carved at the right end of the fixing frame on the left, and a toothed plate and a gear are provided in the receiving groove. The toothed plate is located at the front end of the gear, and the toothed plate is meshed with the gear. The right end of the toothed plate is fixedly connected to the fixing frame on the right, and the upper end of the fixing frame on the left is fixedly connected to an adjusting box, and the upper end of the gear is fixedly connected to an adjusting rod, and the upper end of the adjusting rod rotates through the fixing frame and is fixedly connected to a turbine, and the right end of the adjusting box rotates through a knob, and a worm is fixed on the outer surface of the knob, and the turbine is meshed with the worm.

[0007] In the above-mentioned rail drilling device, the width between the two fixing frames is adjusted so that the fixing frame is sleeved on the upper end of the rail, and at the same time, it is assisted in fixing by the electromagnetic suction cup. The connection is simple, easy to disassemble and assemble, convenient for drilling holes in different positions of the rail, and can effectively improve the fastening between the rail and the drilling device, thereby effectively reducing the displacement of the device during the drilling process and effectively improving the drilling accuracy.

[0008] As a further improvement of the present application, a limiting groove is cut on the front inner wall of the left fixing frame, and the end of the tooth plate away from the gear is fixedly connected to the limiting block, and the limiting block is slidably connected to the limiting groove.

[0009] As a further improvement of the present application, two support blocks are fixedly connected to the lower end of the base plate, and a handle is fixedly connected to the right end of the mounting plate.

[0010] As a further improvement of the present application, the fixing frame is U-shaped as a whole, and anti-slip grooves are provided on the corresponding ends of the two fixing frames.

[0011] As another improvement of the present application, a positioning block is fixedly connected to the outer surface of the motor, the lower end of the positioning block is fixedly connected to two support rods, and two fixing grooves are drilled at the upper end of the base plate.

[0012] As another improved supplement of the present application, the lower end of the support rod extends into the fixing groove, and the lower end of the support rod is slidably connected to the inner wall of the fixing groove.

[0013] To sum up, in actual application, rotating the knob forward causes the worm to rotate, thereby driving the turbine and gear to rotate, and the toothed plate meshing with the gear also moves accordingly, thereby increasing the distance between the two fixing frames, and the rail can be clamped between the two fixing frames. Then, rotating the knob in the opposite direction causes the toothed plate to reset, reducing the distance between the two fixing frames until the rail contacts the longitudinal surfaces of the two fixing frames, and then the two electric telescopic rods are activated to extend so that the electromagnetic suction cup fits the surface of the rail, and the electromagnetic suction cup is activated to attract the rail, thereby firmly connecting the rail to the drilling device, which is convenient for disassembly and assembly, and convenient for drilling holes in different positions of the rail, and can effectively improve the tightness between the rail and the drilling device, thereby effectively reducing the displacement of the device during the drilling process and effectively improving the drilling accuracy.

Figure 1 Point A in the middle is the rail.

[0025] Figure 4 and Figure 5It is shown that the fixing assembly includes two fixing frames 10, which are U-shaped as a whole, and the corresponding ends of the two fixing frames 10 are provided with anti-slip grooves, which can effectively increase the friction between the rail and the fixing frame 10, thereby effectively improving the stability of the fixing frame 10 when in use. The fixing frame 10 on the right is fixedly connected to the positioning plate 2, and the right end of the fixing frame 10 on the left is provided with a receiving groove 11, and a tooth plate 12 and a gear 13 are provided in the receiving groove 11.
