Description

Technical Field

[0001] This utility model relates to the field of railway engineering and rail transit, and in particular to a fully automatic railway appearance shaping machine. Background Technology

[0002] With the development of railway transportation and the increase in train speed, the smoothness and geometry of the tracks place higher demands on the safety and comfort of train operation. Over long-term use, railway tracks are subject to wear, cracks, bending, or geometric misalignment due to the repeated impacts and vibrations from passing trains, as well as the influence of the natural environment (such as foundation settlement and temperature changes). These defects not only affect the smoothness of train operation but may also lead to safety hazards. Therefore, regular track maintenance and reshaping are particularly important.

[0003] However, existing track maintenance equipment suffers from shortcomings in practical applications, including low detection accuracy, limited functionality, unstable operation, and low automation levels. Due to the lack of a high-precision track geometry detection system, inspectors cannot monitor track offset, bending, and surface defects in real time. Furthermore, its functionality is limited to single repair operations, such as grinding or simple adjustments, failing to achieve comprehensive maintenance and resulting in low work efficiency. Track straightening machines are susceptible to track unevenness or their own swaying during operation, leading to significant straightening errors. Simultaneously, traditional equipment relies on manual or semi-automated operation, resulting in high labor intensity and complex operation, hindering efficient large-scale operations.

[0004] To address the above issues, a fully automated railway appearance shaping machine is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fully automatic railway appearance shaping machine, which aims to solve the problems of low detection accuracy, single function, unstable operation and low level of automation in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic railway appearance shaping machine, comprising a front frame and a rear plate, the front frame and the rear plate being fixedly connected, three crossbeams being installed side by side inside the front frame, a drive assembly being provided at the bottom of the crossbeams for driving the equipment to run, two T-slots being symmetrically opened inside the rear plate on the side away from the front frame, a grinding assembly being provided inside the T-slots, a cavity being opened inside the rear plate, a fixing assembly being provided inside the cavity for fixing the equipment, and an adjustment assembly being provided at the bottom of the rear plate for applying a restoring force to the curved parts of the track;

[0007] The drive assembly includes a motor, a drive shaft, and four rollers. The drive shaft is rotatably connected between the interiors of the two crossbeams. The motor is located at the bottom of the middle crossbeam, and the output shaft of the motor is connected to the drive shaft via a drive belt. Two rollers are fixed at both ends of the drive shaft, and the other two rollers rotate inside the drive shaft via driven shafts. The driven shafts are connected to the drive shaft via a drive belt.

[0008] As a further description of the above technical solution:

[0009] A control box and a laser rangefinder are respectively installed at the top and bottom of the crossbeam in the middle section, and a motor is installed at the top of the rear plate.

[0010] As a further description of the above technical solution:

[0011] The fixing assembly includes two L-shaped clamping plates. Racks and limiting strips are fixedly connected to the top sides of the two L-shaped clamping plates. The racks have grooves inside. The output end of the second motor is connected to a gear. The gear is located in the middle of the two racks. Both racks mesh with the gear, and their directions of movement are opposite.

[0012] As a further description of the above technical solution:

[0013] The rack at the top of one of the L-shaped clamping plates is slidably connected to the limiting strip at the top of the other L-shaped clamping plate, and a slider is provided between the groove inside the rack and the inside of the limiting strip.

[0014] As a further description of the above technical solution:

[0015] The two L-shaped clamping plates are slidably connected to the bottom of the rear plate, and their movement directions are opposite.

[0016] As a further description of the above technical solution:

[0017] The adjustment assembly includes two fixing plates, which are fixedly connected to the bottom of the rear plate. Hydraulic push rods are fixedly connected to opposite sides of the two plates, and force-bearing blocks are installed at the output ends of the hydraulic push rods.

[0019] The grinding assembly includes an electric grinding wheel grinder, and a limiting block is fitted on the outer side of the electric grinding wheel grinder. The limiting block is slidably connected inside the T-slot.

[0020] As a further description of the above technical solution:

[0021] A spring is provided between the limiting block and the inner wall of the T-slot.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, a laser rangefinder is installed on the equipment. When the equipment moves on the track, it can detect the track's geometry, curvature, and offset in real time, and transmit the data to the control box for processing. This high-precision detection and feedback mechanism ensures the accuracy of track straightening work, avoids errors that may be caused by human operation, and makes track repair more precise and reliable.

[0024] 2. In this invention, the four rollers of the drive assembly enable smooth equipment movement, which, combined with the grinding assembly, efficiently repairs cracks, irregular wear, and protrusions on the track surface.

[0033] 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.

[0034] Reference Figure 1 This utility model provides an embodiment of a fully automatic railway track shaping machine, comprising a front frame 1 and a rear plate 2. The front frame 1 and the rear plate 2 are fixedly connected to form a stable overall frame structure, providing the foundation for equipment operation and the installation of various functional modules. Three crossbeams 3 are neatly arranged side-by-side inside the front frame 1. These three crossbeams 3 not only support the main structure of the equipment but also provide a stable installation platform for various functional components. A control box 5 is installed at the top of the middle crossbeam 3, which is responsible for the operation management and control system of the equipment. A laser rangefinder 6 is installed at the bottom of the middle crossbeam 3. This is a high-precision measuring tool used to detect the geometry, curvature, and offset of the track in real time, ensuring that the shaping work of the equipment can be carried out accurately.

[0035] The drive assembly 4 is designed at the bottom of the crossbeam 3 to propel the shaping machine smoothly along the track. The core of the drive assembly 4 includes a motor 41, a drive shaft 42, and four rollers 43. The drive shaft 42 is mounted between the two crossbeams 3 and rotatably connected to its internal structure. The motor 41 is fixed to the bottom of the middle crossbeam 3, and its output shaft is connected to the drive shaft 42 via a transmission belt 44, providing stable power to the equipment. Two rollers 43 are fixed at both ends of the drive shaft 42; these rollers 43 are responsible for contacting the track and propelling the equipment forward. In addition, two other rollers 43 are connected to the crossbeam 3 via driven shafts 45, which are also connected to the drive shaft 42 via transmission belts 44, ensuring synchronous operation between the rollers 43. This drive design not only ensures efficient power transmission but also guarantees smooth equipment operation and adapts to the complex environment of the track.

[0036] Reference Figure 2 and Figure 5 The rear plate 2 at the tail of the equipment is also an important part of the whole machine, integrating multiple functional modules to meet various needs for track shaping and repair. On the side of the rear plate 2 away from the front frame 1, there are two symmetrical T-slots 8 designed to install and guide the grinding assembly 11. The core of the grinding assembly 11 is an electric grinding wheel grinder 111, whose main function is to grind and repair the track surface, eliminating defects such as surface cracks, irregular wear, or protrusions. To ensure the stability of the grinder during operation, a limiting block 112 is fitted on its exterior, which can be slidably installed in the T-slots 8. In addition, a spring 113 is provided between the limiting block 112 and the inner wall of the T-slot 8. Through the elasticity provided by the spring 113, the grinding assembly 11 can adapt to small changes in the track surface during operation, further improving the uniformity and effect of grinding.

[0037] Reference Figure 2 - Figure 4 The rear plate 2 has an internal cavity 12, in which a fixing component 9 is installed. This component is primarily used to securely fix the equipment during track shaping. The fixing component 9 consists of two L-shaped clamping plates 91. Racks 93 and limiting strips 95 are respectively installed on the top sides of these clamping plates. The racks 93 have grooves 94, and the racks 93 and limiting strips 95 are slidably connected by sliders 96, ensuring smooth movement and accurate positioning of the clamping plates during operation. The fixing component 9 is powered by a motor 7 mounted on the top of the rear plate 2. The output end of the motor 7 is connected to a gear 92, which is located between and meshes with the two racks 93. Through the forward and reverse rotation of the motor 7, the gear 92 drives the two racks 93 to move in opposite directions, thereby driving the two L-shaped clamping plates 91 to clamp or release the sleepers in the track. Furthermore, the two L-shaped clamping plates 91 are slidably connected to the bottom of the rear plate 2, with their directions of movement opposite to each other. This design makes the clamping action more stable and reliable.

[0038] Reference Figure 2 An adjustment assembly 10 is installed at the bottom of the rear plate 2, specifically designed to apply restoring force to the curved sections of the track. The adjustment assembly 10 consists of two fixing plates 101 and a hydraulic push rod 102. The fixing plates 101 are fixedly installed at the bottom of the rear plate 2, providing a mounting point for the hydraulic push rod 102. The output end of the hydraulic push rod 102 is connected to a force-receiving block 103, which is in direct contact with the track. When the hydraulic push rod 102 is activated, the force-receiving block 103 applies precise pressure or tension to the curved sections of the track, thereby restoring the track to its standard shape.

[0039] Working Principle: After the equipment starts, motor 41 drives four rollers 43 through transmission shaft 42 and transmission belt 44, moving the equipment along the track. Laser rangefinder 6 monitors the track's geometry and offset in real time, transmitting the data to control box 5 for processing. When a track surface defect is detected, electric grinding wheel 111, installed in the T-slot 8 of the rear plate 2, repairs and grinds the track surface under the support of limit block 112 and spring 113. When the equipment needs to be fixed, motor 7 drives gear 92 to rotate, meshing with racks 93 on the top of two L-shaped clamping plates 91. This allows the clamping plates to slide relative to each other under the guidance of slider 96, securing the sleepers and preventing wobbling during track shaping. When track curvature is detected, adjustment assembly 10 is activated, and hydraulic push rod 102 pushes force block 103, applying a restoring force to the curved section of the track under the support of fixing plate 101, correcting track offset. Through the coordinated operation of these steps, the equipment achieves efficient track shaping and repair.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
