Description

TECHNICAL FIELD

[0001] The utility model relates to track maintenance equipment technical field especially relates to a steel rail drilling machine fixed clamping seat and mounting structure. BACKGROUND

[0002] The point rail is an important component in the turnout switch, and the point rail can be pulled by the dispatching control system to guide the train to the main line or the side line.

[0003] When the point rail needs to be repaired or replaced in the installation of the point rail at the turnout of the newly built railway line and the maintenance operation, the steel rail drilling machine is often used to drill holes on the point rail to connect and fix it with the standard rail.

[0004] The related technology is disclosed in the Chinese patent with the patent number CN201922075721.X, which discloses a steel rail drilling machine. The drilling machine is clamped on the two side end faces of the steel rail through the clamping mechanism. Then, the circumferential rotation of the motor transmission speed reduction mechanism drives the feed transmission mechanism to rotate circumferentially. The movement of the feed transmission mechanism drives the drill bit to rotate circumferentially. The rotation of the rotating handle mechanism around its center line drives the feed transmission mechanism carrying the drill bit to move towards or away from the side end face of the steel rail. Thus, the drilling operation on the steel rail is realized. The clamping mechanism includes the first lever plate arranged in the opposite mode, the screw rod arranged between the first lever plates, the rotating handle arranged at the end of the screw rod, and the second lever plate hinged to the corresponding side of the first lever plate. The bottom end of the first lever plate is provided with the first clamping part with the opening facing the vertical plate. The bottom end of the vertical plate is provided with the second clamping part facing the first lever plate. The first clamping part and the second clamping part are respectively located on the two sides of the steel rail and abut the corresponding side end face of the steel rail.

[0005] According to the above prior art, the distance between the second clamping part abutting the end face of the steel rail and the drill bit is the drilling depth. However, the second clamping part for clamping the rail has a fixed installation position. Since the thickness, slope of the rail head, rail waist and rail bottom, and the cross-sectional form and geometric dimensions of the standard rail section are different, the drill bit of the drilling equipment needs to be disassembled and replaced with a drill bit of different length for continuous operation when drilling at different positions of the point rail. This requires maintenance personnel to carry multiple drill bits, which is time-consuming and laborious to disassemble and assemble, and is not convenient to operate. UTILITY MODEL CONTENTS

[0006] To solve the problem that the drill bit of the drilling equipment needs to be disassembled and replaced with a drill bit of different length for continuous operation when drilling at different positions of the point rail in the prior art, which is time-consuming and laborious to disassemble and assemble, and is not convenient to operate, the utility model provides a drilling machine fixed clamping seat, which can conveniently adjust the drilling depth of the drill bit and complete the drilling operation on the point rail with different thicknesses.

[0007] To achieve the above object, the following technical solutions are provided:

[0009] Further, the bottom of the first and second fork-shaped top plates is provided with an angle of attack inclined surface.

[0010] Further, the length of the first fork-shaped top plate is 30-40 mm, and the width of the fork of the first fork-shaped top plate is 40-55 mm.

[0011] Further, the length of the second fork-shaped top plate is 40-45 mm, and the width of the fork of the second fork-shaped top plate is 30-35 mm.

[0014] Further, one or more transverse strip-shaped holes are arranged on the clamping seat body, mounting holes corresponding to the transverse strip-shaped holes on the clamping seat body are arranged on both sides of the drilling machine body, a limiting seat is fixed on the rear side of the body of the mounting hole, a screw hole is arranged on the limiting seat, a bolt is arranged in the screw hole, and one end of the bolt abuts against the rear side of the fixed clamping seat.

[0015] The use principle of the utility model is that, since the thickness and slope of the rail head, rail waist and rail bottom of the switch rail are different from the standard rail section form and geometric size, when drilling the switch rail, the mounting position of the fixed clamping seat on the drilling machine body can be adjusted, the distance between the fixed clamping seat abutting against one end of the rail waist of the switch rail and the drill bit is adjusted, and thus the drilling needs of the switch rail with different thicknesses of the rail waist can be adapted.

[0023] The following description, in conjunction with embodiments, further illustrates the present invention's fixed bracket and installation structure for a rail drilling machine.

[0024] like Figure 1 , Figure 2 As shown, a rail 21 drilling machine fixing bracket includes a plate-shaped bracket body 1, with a first fork-shaped top plate 2 and a second fork-shaped top plate 3 respectively on both sides of the bracket body 1, and a transverse strip hole 4 or an adjustment hole 5 composed of multiple transversely distributed holes on the bracket body 1.

[0025] In this embodiment, the fixing bracket is cut from a steel plate with a thickness of 10mm-15mm to ensure its structural strength. The first fork-shaped top plate 2 and the second fork-shaped top plate 3 are cut from the steel plate, and both fork-shaped top plates are used to support the web of the switch rail 22. The transverse strip holes 4 are preferably arranged in multiple parallel rows to improve the installation stability on the drilling machine body.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the bottom of the first fork-shaped top plate 2 and the second fork-shaped top plate 3 are both provided with an angle-of-attack slope 6. Since the upper part of the rail bottom is arc-shaped, the shape of the angle-of-attack slope 6 matches the rail bottom, which can stably hold the bottom of the rail during the clamping of the tip rail 22.

[0027] The length of the first forked top plate 2 is 30mm-40mm, and the width of the fork of the first forked top plate 2 is 40mm-55mm.

[0028] The length of the second fork-shaped top plate 3 is 40mm-45mm, and the width of the fork opening is 30mm-35mm. In this design, fork-shaped top plates of different sizes are provided on both sides of the mounting base 1. Depending on the actual situation, a suitable end can be selected for installation, resting against the rail web. In this embodiment, the length of the first fork-shaped top plate 2 is 35mm, and the width of the fork opening is 48mm; the length of the second fork-shaped top plate 3 is 40mm, and the width of the fork opening is 30mm. These dimensions are only specified to correspond to the actual working conditions of the switch rail 22.

[0029] An installation structure for a rail 21 drilling machine fixing bracket includes a drilling machine body 10 and the aforementioned fixing bracket. On both sides of the drilling machine body 10, there are mounting holes 7 corresponding to the positions of the transverse strip holes 4 or adjustment holes 5 on the bracket body 1. The number of mounting holes 7 is at least two. The fixing bracket is fixed to the mounting holes 7 by bolts 9.

[0030] like Figure 3 , Figure 4 , Figure 5As shown, the rail 21 drilling machine includes a drilling machine body 10 and a clamping mechanism; fixed brackets are installed on the drilling machine body 10 on both sides of the drill bit 12; a motor mechanism 11 is installed on the drilling machine body 10, which can be powered by a battery or wire, and the output end of the motor mechanism 11 is connected to the drill bit 12; the clamping mechanism includes a rotating handle 13, an adjusting rod 14, a clamping rod 15, a clamping bracket 16, a connecting seat 17, and a clamping element 20. The middle section of the clamping rod 15 is rotatably mounted on the clamping bracket 16, and the upper end of the clamping rod 15 is rotatably mounted on a connecting shaft 19. The middle part of the connecting shaft 19 is provided with an internal thread. The connecting seat 17 is rotatably mounted on the drilling machine body 10, and one end of the adjusting rod 14 is rotatably mounted on the connecting seat 17, that is, the adjusting rod 14 can rotate around its own axis. The middle section of the adjusting rod 14 has an external thread that mates with the internal thread of the connecting shaft 19; the rotating handle 13 is connected to the adjusting rod 14; by rotating the rotating handle 13, the adjusting rod 14 is rotated, and the adjusting rod 14 is threadedly connected to the connecting shaft 19 of the clamping rod 15, thereby causing one end of the clamping rod 15 to move along the external thread of the adjusting rod 14, and the clamping member 20 at the other end of the clamping rod 15 clamps onto the rail web on one side of the rail 21, and the fixed chuck abuts against the rail web of the switch rail on the other side of the rail 21, thereby achieving the effect of clamping the rail and the switch rail. Rotating the rotating handle in the opposite direction will achieve the effect of loosening. Since the thickness, slope and cross-sectional shape and geometric dimensions of the rail head, rail web and rail bottom of the switch rail 22 are different from those of the standard rail, when drilling the switch rail 22, the installation position of the fixed chuck on the drilling machine body 10 can be adjusted to adjust the distance between the fixed chuck abutting one end of the switch rail web and the drill bit 12, thereby adapting to the drilling needs of switch rails with different thicknesses of rail web. The drilling machine in this embodiment may be, but is not limited to, the drilling machine in CN201922075721.X.

[0031] In one embodiment, such as 1, Figure 5 As shown, when the clamping body 1 has one or more layers of transverse strip holes 4, the two sides of the drilling machine body 10 for the rail 21 are provided with mounting holes 7 corresponding to the transverse strip holes 4 on the clamping body 1. A limiting seat 8 is fixed on the rear side of the machine body with mounting holes 7. The limiting seat 8 has screw holes, and bolts 9 are installed in the screw holes. One end of the bolt 9 abuts against the rear side of the fixed clamping seat to prevent the transverse strip holes 4 from moving backward during the clamping of the rail 21. The limiting seat 8 can be a steel plate, welded to the drilling machine body. In this embodiment, the transverse strip holes 4 are provided in three layers and are stamped.
