Description

Technical Field

[0001] This utility model relates to the technical field of track repair devices, specifically a track contour shaping tool assembly. Background Technology

[0002] With the rapid development of modern industry, high-speed railways and urban rail transit have gradually become indispensable modes of transportation in people's lives. Rail transit has the advantages of high efficiency and safety and stability. Therefore, in order to develop rail transit, a large number of tracks need to be laid. However, tracks are prone to deformation and damage in daily use, and need to be repaired regularly to ensure the safety and reliability of the tracks during use. Therefore, we propose a track contour shaping tool assembly.

[0003] The existing technology still has the following drawbacks in its use:

[0004] In the existing track contour shaping tool assembly, the tool and track need to slide relative to each other continuously during the trimming process to achieve track trimming. However, long-term sliding friction not only easily generates high temperatures that affect the tool's performance, but also leads to greater tool wear, thereby reducing the tool's durability.

[0005] In view of this, we propose a trajectory profile shaping tool assembly to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to provide a track contour shaping tool assembly to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a track contour shaping tool assembly for trimming tracks, comprising a trimming assembly and a driving assembly, wherein the driving assembly comprises a connecting block, base plates are fixedly installed on the front and rear sides of the connecting block, and the side of the base plate away from the connecting block is set as an inclined surface, and two sets of electric telescopic rods are fixedly installed on the inclined surface of the base plate.

[0008] The end of the electric telescopic rod away from the base plate is equipped with a trimming assembly. The trimming assembly includes two contour covers. The contour covers are arch-shaped structures, and a repair blade is fixedly installed on the inner side of the contour covers. Two limiting rods are installed through the inside of the contour covers, and the limiting rods pass through the two contour covers. A connecting plate is fixedly installed on the top of the contour covers, and a fixing plate is fixedly installed on one side of the connecting plate.

[0009] The bottom of the contour cover is fitted with a track.

[0010] Preferably, a controller is fixedly installed on the left or right side of the connecting block, and the controller is electrically connected to the electric telescopic pole via a wire.

[0011] Preferably, an I-beam is fixedly installed on the top of the connecting block, and four fixing bolts are installed on the top of the I-beam through a threaded structure.

[0012] Preferably, two contour covers extend from both ends of the limiting rod, and limiting wheels are fixedly installed at both ends of the limiting rod.

[0013] Preferably, the side of the fixing plate away from the connecting plate is set as an inclined surface, and the inclined surface of the fixing plate is fixedly connected to one end of the electric telescopic rod.

[0014] Preferably, the inclined surface on one side of the fixing plate has the same inclination angle as the inclined surface on one side of the base plate, and the two inclined surfaces are installed opposite each other.

[0015] Preferably, a buffer ring is fixedly installed on one side of each of the two contour covers facing each other, and the cross-sectional radius of the buffer ring is greater than the length of the repair blade extending out of the contour cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model installs a drive assembly between two contour covers, which elastically connects the two contour covers simultaneously. After the drive assembly is connected to the vehicle body, the vehicle body moves at a constant speed along the track, driving the drive assembly and the trimming assembly to move. During the movement, the sliding friction between the contour cover and the track and the elastic force applied to the contour cover by the electric telescopic rod enable the two contour covers to move back and forth along the track at a high frequency, thereby trimming the track. This not only improves the trimming effect of the device on the track, but also avoids the serious wear of the tool caused by continuous sliding.

[0018] 2. This utility model, by installing a limiting rod inside the contour cover, can keep the two contour covers working on the same horizontal plane. Furthermore, by using the mutual restraint between the two separate contour covers, it can ensure that the two contour covers maintain the same movement path during the trimming process. This ensures that the two contour covers have a consistent trimming effect on the track, avoids the occurrence of potholes during track trimming, and improves the working efficiency of the device.

[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 track contour shaping tool assembly for trimming track 1. It includes a trimming component 2 and a drive component 3. The drive component 3 includes a connecting block 302. Base plates 303 are fixedly installed on the front and rear sides of the connecting block 302. The side of the base plate 303 away from the connecting block 302 is set as an inclined surface. Two sets of electric telescopic rods 301 are fixedly installed on the inclined surface of the base plate 303. The drive component 3 can connect to the vehicle body and thus drive the entire device to move. The connecting block 302 can connect and install the surrounding components, so that multiple components can work together. The base plate 303 can provide an installation position for one end of the electric telescopic rod 301 and install the electric telescopic rod 301 at an angle downward. This allows the electric telescopic rod 301 to apply an inclined downward elastic force to the contour cover 201. This allows the electric telescopic rod 301 to not only elastically connect the two contour covers 201, but also apply downward pressure to the contour cover 201, so that the contour cover 201 can drive the repair blade 206 to fit against the surface of the track 1 for trimming.

[0026] A trimming assembly 2 is installed at the end of the electric telescopic rod 301 away from the base plate 303. The trimming assembly 2 includes two contour covers 201, each with an arch-shaped structure. A repair blade 206 is fixedly installed on the inner side of each contour cover 201. Two limiting rods 204 are installed through the inside of each contour cover 201, passing through both contour covers 201. A connecting plate 202 is fixedly installed on the top of each contour cover 201, and a fixing plate 203 is fixedly installed on one side of the connecting plate 202. The trimming assembly 2 can move synchronously with the drive assembly 3 and engage with the track 1 to trim the track 1. The contour cover 201 can trim the surrounding components. The mounting position is provided and it engages with the track 1, so that the repair blade 206 repairs the surface of the track 1 as the contour cover 201 moves. The limiting rod 204 can pass through the two contour covers 201 to limit the contour covers 201 and ensure that the two contour covers 201 can work on the same horizontal plane, ensuring the repair effect of the two contour covers 201 and their surrounding components on the track 1. The connecting plate 202 can provide a mounting position for the fixing plate 203. The fixing plate 203 can be connected to one end of the electric telescopic rod 301, so that the connecting block 302 can be elastically connected to the contour cover 201 through the electric telescopic rod 301.

[0027] The bottom of the contour cover 201 is fitted with a track 1.

[0028] Furthermore, a controller is fixedly installed on the left or right side of the connecting block 302, and the controller is electrically connected to the electric telescopic rod 301 through a wire. The controller can control the extension length of the electric telescopic rod 301, thereby controlling the magnitude of the elastic force on the contour cover 201.

[0029] Furthermore, an I-beam 305 is fixedly installed on the top of the connecting block 302, and four fixing bolts 304 are installed on the top of the I-beam 305 through a threaded structure. The I-beam 305 and the fixing bolts 304 can connect the drive assembly 3 to the external vehicle body, thereby enabling the entire device to move synchronously with the vehicle body.

[0030] Furthermore, two contour covers 201 extend from both ends of the limiting rod 204, and limiting wheels are fixedly installed at both ends of the limiting rod 204. The limiting wheels can limit the movement range of the contour covers 201, thereby enabling the contour covers 201 to move along the limiting rod 204.

[0031] Furthermore, the side of the fixing plate 203 away from the connecting plate 202 is set as an inclined surface, and the inclined surface of the fixing plate 203 is fixedly connected to one end of the electric telescopic rod 301.

[0032] Furthermore, the inclined surface on one side of the fixing plate 203 has the same inclination angle as the inclined surface on one side of the base plate 303, and the two inclined surfaces are installed opposite each other.

[0033] Furthermore, buffer rings 205 are fixedly installed on one side of the two contour covers 201 in opposite directions, and the cross-sectional radius of the buffer rings 205 is greater than the length of the repair blade 206 extending out of the contour cover 201.

[0034] Working principle: After the device is assembled and checked to ensure it is correct, the length of the electric telescopic rod 301 is adjusted by the controller to engage the contour cover 201 with the track 1. The device is connected to the vehicle body through the drive component 3. When the vehicle body moves the device, the electric telescopic rod 301 applies elastic force to the contour cover 201, causing the two contour covers 201 and their surrounding components to move along the guide rail. During the movement, the two contour covers 201 are subjected to the downward elastic force applied by the electric telescopic rod 301 and the sliding friction between the repair blade 206 and the track 1, causing the two contour covers 201 to move back and forth along the limit rod 204. This causes the repair blade 206 to vibrate at high frequency to repair the surface of the track 1, improving the device's repair effect on the track 1.

[0035] 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.
