Abstract
Description
Technical Field
[0001] This utility model relates to the field of milling cutter technology, specifically a multi-functional track maintenance milling cutter. Background Technology
[0002] A track maintenance milling cutter is a tool used in track maintenance work to mill and repair defects on the track surface. By milling the track during track maintenance, the safety of the track in subsequent use can be ensured. In order to improve the durability and convenience of track maintenance milling cutters, we propose a multi-functional track maintenance milling cutter.
[0003] The existing technology still has the following drawbacks in its use:
[0004] 1. The durability of existing multi-functional track maintenance milling cutters mainly depends on the strength of the materials used to manufacture the milling cutters. Therefore, they are highly dependent on the materials. After use, the milling marks on the milling cutters gradually wear down, which affects the effectiveness of subsequent track maintenance and reduces the durability of the milling cutters.
[0005] 2. Existing multi-functional track maintenance milling cutters cannot guarantee full contact with the track. Consequently, during the milling and repair process, incomplete contact with the track at certain locations can lead to a decrease in the repair effect in some areas, resulting in inconsistent track performance during subsequent use.
[0006] In view of this, we propose a multi-functional track maintenance milling cutter to solve the existing problems. Utility Model Content
[0007] The purpose of this invention is to provide a multifunctional track maintenance milling cutter to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional rail maintenance milling cutter, comprising a rail, a cutter holder, and a triangular plate. A base plate is installed at the bottom of the cutter holder, and two sets of cutting plates are provided at the bottom of the base plate. The two sets of cutting plates are staggered, and the thickness of one set of cutting plates is twice the thickness of the other set of cutting plates. A top plate is fixedly installed at the top of the cutter holder, and a fixing anchor is installed through the inside of the cutter holder. Both ends of the fixing anchor are engaged with limiting plates. The limiting plates are polygonal pieces and are embedded inside the top plate and the base plate.
[0009] The bottom of the tool holder is provided with a steel rail, and the steel rail is in contact with the cutting plate.
[0010] A triangular plate is installed on the top of the top plate. Three adjusting bolts are rotatably installed inside the triangular plate. A threaded cylinder is installed on the outer side of the bottom end of the adjusting bolts through a threaded structure. The bottom of the threaded cylinder is a ball-shaped structure, and a ball head seat is snapped onto the outer side of the bottom of the threaded cylinder. The top of the ball head seat is a hollow open structure, and the ball head seat is snapped onto the bottom of the threaded cylinder.
[0011] Preferably, a polygonal groove is provided at the center of both the top plate and the bottom plate, and the groove inside the top plate and the bottom plate matches the limiting piece.
[0012] Preferably, the tool holder is a parallelogram-shaped plate, and the interior of the tool holder has a longitudinal through hole for connection with the fixed anchor bolt.
[0013] Preferably, both the top plate and the bottom plate have concave cutting surfaces on their sides, and the width of both the top plate and the bottom plate is smaller than that of the tool holder.
[0014] Preferably, a connecting seat is bolted to the top of the triangular plate, and a mounting seat is welded to the top of the connecting seat.
[0015] Preferably, the mounting base has an extended plate-like structure at its top edge, and mounting holes are provided around the top of the mounting base.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model has two sets of cutting plates with different thicknesses at the bottom of the base plate. When the device comes into contact with the track and slides, it can not only ensure the cutting and repair effect on the track surface, but also allow the first set of cutting plates to cooperate with the second set of cutting plates to cut and repair the track surface again after the first set of cutting plates wears out. This allows the device to maintain a good cutting effect even after a period of use.
[0018] 2. This utility model has a triangular plate installed on the top of the tool holder. With the triangular plate, three adjusting bolts and a threaded cylinder working together, the height and angle of the triangular plate and the tool holder at the bottom can be adjusted while the top of the device is fixed. This allows the cutting plate to fit completely against the track surface, thus ensuring the repair effect of the device during cutting and repair. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] like Figure 1 - Figure 4 As shown, this utility model proposes a multi-functional track maintenance milling cutter, including a rail 1, a cutter holder 2, and a triangular plate 3. A base plate 202 is installed at the bottom of the cutter holder 2, and two sets of cutting plates 203 are arranged at the bottom of the base plate 202. The two sets of cutting plates 203 are staggered, and the thickness of one set of cutting plates 203 is twice the thickness of the other set. A top plate 201 is fixedly installed on the top of the cutter holder 2. A fixing bolt 204 is installed through the interior of the cutter holder 2, and both ends of the fixing bolt 204 are engaged with limiting pieces 205. The limiting pieces 205 are polygonal sheets and are embedded inside the top plate 201 and the base plate 202. The cutter holder 2 can maintain the surrounding track. The components provide installation positions. The cutting plates 203 are all cross-shaped plates that can cut the track surface when the device slides relative to the track, thereby repairing the track. The top plate 201 can be used with the fixing anchor bolts 204 to fix the bottom plate 202, so that the bottom plate 202 and the top plate 201 can be replaced separately, which facilitates the maintenance of the device in the later stage and reduces the maintenance cost of the device. The fixing anchor bolts 204 can penetrate the top plate 201, the tool holder 2 and the bottom plate 202, and then work with the limiting piece 205 to connect and fix the three together, so that the three maintain a stable structure after assembly, which facilitates the movement of the cutting plates 203 to complete the cutting and repair of the track.
[0026] The bottom of the tool holder 2 is provided with a steel rail 1, and the steel rail 1 is in contact with the cutting plate 203.
[0027] A triangular plate 3 is mounted on the top of the top plate 201. Three adjusting bolts 302 are rotatably mounted inside the triangular plate 3. A threaded cylinder 305 is threaded onto the outer side of the bottom end of each adjusting bolt 302. The bottom of the threaded cylinder 305 has a ball-head shape, and a ball head seat 301 is snapped onto the outer side of the bottom of the threaded cylinder 305. The top of the ball head seat 301 has a hollow, open structure, and the ball head seat 301 engages with the bottom of the threaded cylinder 305. The triangular plate 3 provides mounting positions for surrounding components and allows for adjustment. Bolt 302 rotates internally, and adjusting bolt 302 can extend into the interior of threaded cylinder 305. The distance and angle between triangular plate 3 and top plate 201 can be adjusted through the threaded structure between them, so that the installation position of the device can be adjusted during debugging, so that cutting plate 203 can fit against the surface of the track. Ball head seat 301 can be connected to the ball head structure at the bottom of threaded cylinder 305, so that the angle between threaded cylinder 305 and adjusting bolt 302 can be changed when adjusting bolt 302 is rotated.
[0028] Furthermore, a polygonal groove is provided at the center of both the top plate 201 and the bottom plate 202, and the groove inside the top plate 201 and the bottom plate 202 matches the limiting piece 205. When the polygonal groove inside the top plate 201 and the bottom plate 202 matches the limiting piece 205, the installation stability of the fixed anchor bolt 204 can be guaranteed, thereby preventing slippage between the top plate 201 and the bottom plate 202 and the tool holder 2.
[0029] Furthermore, the tool holder 2 is a parallelogram-shaped plate, and the interior of the tool holder 2 has a longitudinal through hole for connection with the fixed anchor bolt 204.
[0030] Furthermore, both the top plate 201 and the bottom plate 202 have concave cutting surfaces on their sides, and the widths of both the top plate 201 and the bottom plate 202 are smaller than the tool holder 2.
[0031] Furthermore, a connecting seat 303 is bolted to the top of the triangular plate 3, and a mounting seat 304 is welded to the top of the connecting seat 303. The connecting seat 303 and the mounting seat 304 can be fixedly connected to the external structure by bolts, so that the device can be moved as a whole by the external structure, thereby facilitating the cutting and repair of the track.
[0032] Furthermore, a plate-like structure is provided at the top edge of the mounting base 304, and mounting holes are provided around the top of the mounting base 304.
[0033] Working principle: After the mounting base 304 is fixedly connected to the external drive structure by bolts, the installation position and angle of the tool holder 2 and its surrounding components are adjusted by rotating the three adjusting bolts 302, so that the cutting plate 203 is in contact with the track. When the device moves as a whole through the external drive structure, the cutting plate 203 slides relative to the track, and then the cutting plate 203 cuts and repairs the track. After the first set of thicker cutting plates 203 wears down, the thicker set of cutting plates 203 and the thinner set of cutting plates 203 work together to fit against the track surface and cut the track surface, thereby increasing the cutting area of the device on the track, improving the cutting effect, and ensuring the overall cutting effect of the device on the track.
[0034] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
