Description

Technical Field

[0001] The present invention relates to the technical field of track engineering, and in particular to a rapid track starting and shifting device and method for replacing ballastless track slabs of a high-speed railway. Background Art

[0002] Currently, track slab cracks, chipping, and even map-like cracks have been found on operating high-speed railway lines with ballastless tracks. If not promptly addressed, these problems may affect the structural bearing capacity and line geometry, posing a safety hazard. The current track slab replacement technology in China primarily relies on the sawing method:

[0003] 1) There are deficiencies such as increased welds, complicated processes, and low efficiency;

[0004] 2) The traditional rail replacement method involves cutting long, seamless rails and then re-welding them. This process of rail cutting and welding not only directly damages the rails at the replacement site, but also involves multiple construction steps, a long construction period, and a large number of workers. Speed ​​limits are also required until the alignment is fully fine-tuned, significantly impacting the normal operation of the high-speed railway.

[0005] 3) The key control factors for track plate replacement without sawing are the rationality of the process, the feasibility of site conditions, and the development of specialized construction equipment. The key to assessing the success of the operation is the efficiency of the plate replacement operation and the accuracy of the reset of the various parts of the track structure after the plate replacement. However, there is currently no mature track lifting and shifting device for track plate replacement without sawing in China or even abroad.

[0006] 4) During high temperatures in summer and low temperatures in winter, the temperature stress of the rails in the seamless line will cause the rails and other components to not be accurately reset after loosening the fasteners and replacing the rails. At present, the domestic track lifting and track shifting operation is carried out manually using jacks, small track lifters and pads, which is difficult to reset and will occupy several high-speed railway skylight points, which is time-consuming and labor-intensive.

[0007] 5) The track shifting capacity of the track lifting and shifting tools and other special tools currently on the market is less than 200mm, and their operating conditions do not meet the requirements for replacing damaged track plates. There is an urgent need to invent a track lifting and shifting device suitable for replacing damaged track plates.

[0008] 6) According to research, a domestic unit used a small track lifter, jack, hydraulic cylinder, and track shifting sliding platform to lift and shift the track in steps when replacing damaged track slabs on high-speed railways. However, since the rails with the fasteners removed within a 100-meter range are in a free state, the system is not satisfactory under conditions of superelevation, curves, and slopes, and is also very likely to damage the seamless rails of high-speed railways. In addition, the process is complex, the operation time is long, and the device integration is not high.

[0009] Therefore, it is urgent to create a new type of fast track equipment.

[0010] Therefore, it is necessary to provide a fast track-moving device for replacing ballastless track slabs of high-speed railways to solve the above technical problems. Summary of the Invention

[0020] Preferably, the track lifting cylinder is fixedly mounted on the inner wall of the guide cover, and the output end of the track lifting cylinder is fixedly connected to the top of the track lifting telescopic arm, and the outer surface of the track lifting telescopic arm is slidably connected to the inner surface of the guide cover.

[0073] A rapid track-lifting and shifting device for replacing ballastless track slabs on a high-speed railway comprises: a track slab mechanism 1 and a reinforced concrete base 14 on which the rapid track-lifting and shifting device for replacing ballastless track slabs on a high-speed railway is installed, the bottom of the track slab mechanism 1 being mounted on the top of the reinforced concrete base 14; a fastener mechanism 2, the bottom of the fastener mechanism 2 being mounted on the top of the track slab mechanism 1 via a first pressure plate bolt 15; a rail mechanism 3, the rail mechanism 3 being mounted on the top of the fastener mechanism 2; a track-lifting and shifting device 4, the bottom of the track-lifting and shifting device 4 being mounted above the rail mechanism 3, the track-lifting and shifting device 4 comprising a traveling mechanism 5, a rail hooking mechanism 6, a rail shifting mechanism 7, a lifting screw 8, an electrical control mechanism 9, a hydraulic pump station 10, a frame 11, a track-lifting mechanism 12 and a connecting plate mechanism 13.

[0074] The track lifting and shifting device 4 is an essential tool for replacing high-speed railway track plates. It is used to lift and shift the two tracks on the high-speed railway track plate with the fasteners removed at a certain distance. It can not only lift the track longitudinally, but also shift the two tracks outwards at a certain distance laterally. It is mainly used to replace the track plate mechanism 1 cast and embedded on the reinforced concrete base 14, ensuring that the rail mechanism 3 at the damaged track plate with the fasteners removed is shifted out of the damaged track plate mechanism 1, and reserving enough space to use a lifting rail car to lift out the damaged plate and lift in the new plate, thereby achieving the purpose of replacing the track plate.

[0075] It is used to lift and shift the two tracks on the ballastless track with the fasteners removed. It can lift the track 150mm longitudinally and simultaneously shift the two tracks outwards in opposite directions by a certain distance, 770mm on one side. After the operation is completed, the track can be re-tracked.

[0076] The track plate mechanism 1 is a CRTS type track plate, comprising a first track plate 110 and a second track plate 120;

[0077] The first track plate 110 is a CRTS-I type track plate;

[0078] The second track plate 120 is a CRTS-II track plate or a CRTS-III track plate.

[0079] The rapid track slab replacement device for high-speed railway provided by the present invention mainly includes the following functions:

[0080] Track walking function: When the track lifting and shifting device 4 is placed on the track, it can be manually pushed to move the device on the track;

[0081] Longitudinal track lifting function: After the two rail mechanisms 3 are clamped, they can be lifted longitudinally by the track lifting cylinder 1203, with a lifting amount of ≥150mm. During the lifting process, the device is connected to the track plate mechanism 1 and fully utilizes the bolts and mounting holes on the fastener mechanism 2 for installation, ensuring reliable installation;

[0082] Lateral track shifting function: After the rail mechanism 3 is lifted into place, the two rail mechanisms 3 can be shifted laterally towards each other simultaneously by the rail shifting hydraulic cylinder 704. The maximum outward shifting distance on one side can reach 770mm. The left and right rail shifting mechanisms 7 are mechanically locked after being retracted.

[0083] Self-locking function: After the rail is moved into place, the hydraulic cylinder can self-lock, and the self-locking is reliable.

[0084] Reset function: When the rail mechanism 3 needs to be reset, the device can realize action reset and restore the rail mechanism 3 to its original position;

[0085] Track clamping function: It can simultaneously clamp two tracks under the standard track gauge of 1435mm. It adopts manual control to ensure firm and reliable clamping, and quick and easy installation and removal.

[0086] Control system: AC power is used to control the AC motor, which in turn controls the hydraulic system to achieve action. The device is equipped with an electric control box and wiring ports, which can be controlled by both the control box and the wireless remote control. At the same time, the manual control function is retained. In the event of electronic control failure, emergency operation can be performed through the manual hand pump;

[0087] Hydraulic pump station: The device is integrated with a hydraulic pump station, including a hydraulic oil tank, operating handle, solenoid valve, hydraulic hose and pipeline accessories, etc., which provides power source for track lifting, track shifting and resetting.

[0088] like Figure 1 The track lifting and shifting device 4 is mainly composed of a frame 11, two sets of walking mechanism 5, rail hook mechanism 6, rail shifting mechanism 7, track lifting mechanism 12, an electrical control mechanism 9, a hydraulic pump station 10, a connecting plate mechanism 13 and a lifting screw 8. The track lifting and shifting device 4 uses AC380V as the power supply to realize remote control and manual control, while retaining the emergency function of the hand pump. The track lifting and shifting device 4 can be reliably connected with the three track plate mechanisms 1 through two different connecting plate mechanisms 13, and is fastened with the bolts in the fastener mechanism 2.

[0089] The walking mechanism 5 includes four connecting frames 501 and four supporting rollers 502. The surface of the connecting frame 501 is installed on the hook rail mechanism 6 through a pin, and the shaft end of the supporting roller 502 is rotatably installed on the inner surface of the connecting frame 501. The surface of the supporting roller 502 is rollingly connected to the surface of the rail mechanism 3.

[0090] like Figure 2 and Figure 3 The movement of the track-lifting and shifting device 4 is supported by the four supporting rollers 502 on the traveling mechanism 5 to realize walking on the rails, and can be pushed to the track-lifting and shifting working point by the operating personnel;

[0091] The connecting frame 501 on the walking mechanism 5 is fixed to the upper hole of the hook rail mechanism 6 by a pin, and the height adjustment can be achieved through the three holes provided in the longitudinal direction of the connecting frame 501. The three-position adjustment of the connecting frame 501 is manually adjusted by the pins.

[0092] When the track lifting and shifting device 4 is hoisted onto the rail mechanism 3, the connecting frame 501 is installed in advance and the pin is inserted into the highest hole of the connecting frame 501, so that the walking mechanism 5 is connected to the pin hole of the hooking rail mechanism 6, and the second pins 603 of the hooking rail mechanisms 6 on the left and right sides of the track lifting and shifting device 4 are pulled out, so that the movable hook 604 is rotated around the first pin 602 at a certain angle, and then the second pin 603 is reinserted into the original position. At this time, the movable hook 604 is restricted in the walking position, so that it will not affect the movement of the device on the rail mechanism 3;

[0093] At the same time, adjust the extension amount of the track shifting mechanism 7 in advance so that the outer curvature of the four supporting rollers 502 on the walking mechanism 5 coincides with the outer curvature of the two rails of the rail mechanism 3, and ensure that the track lifting mechanism 12 is in a retracted state. At this point, the track lifting and shifting device 4 can be realized to run on the rail mechanism 3, which is convenient for manual pushing to the appropriate point for installation.

[0094] One side of the hook-rail mechanism 6 is fixedly mounted on the surface of the rail-pulling mechanism 7, and the hook-rail mechanism 6 includes a fixed hook 601, two pin holes are provided on the fixed hook 601, and a movable hook 604 is rotatably mounted on the fixed hook 601, and a first latch 602 and a second latch 603 are respectively mounted on the fixed hook 601.

[0095] The surface of the first latch 602 is engaged with the inner surface of one of the pin holes, and the surface of the second latch 603 is engaged with the inner surface of the other pin hole.

[0096] like Figure 4 , the hook-rail mechanism 6 is composed of a fixed hook 601, a first latch 602, a second latch 603 and a movable hook 604. A fixed hook 601 has two sets of pin holes for fixing the movable hook 604 at different angles;

[0097] When walking, the staff uses the first latch 602 to fix the movable hook 604 in the walking position;

[0098] When starting the track, the staff will fix the hook rail position parallel to the fixed hook 601.

[0099] The rail derailing mechanism 7 includes a right rail derailing telescopic arm 701 and a left rail derailing telescopic arm 702. The right rail derailing telescopic arm 701 and the left rail derailing telescopic arm 702 are respectively equipped with corresponding telescopic arm locking mechanisms 703, and the right rail derailing telescopic arm 701 and the left rail derailing telescopic arm 702 are respectively equipped with corresponding rail derailing hydraulic cylinders 704. The right rail derailing telescopic arm 701 and the left rail derailing telescopic arm 702 are fixedly mounted on the inside of the frame 11 by two sets of pins 705.

[0100] like Figure 6 and Figure 7 The main top view of the rail deflection mechanism 7, which is mainly composed of a right rail deflection telescopic arm 701 and a left rail deflection telescopic arm 702, each of which is mainly composed of a rail deflection hydraulic cylinder 704, a pin 705 and a telescopic arm locking mechanism 703;

[0101] Since the maximum track shifting amount is to reach 770mm, the right track shifting telescopic arm 701 and the left track shifting telescopic arm 702 and the two track shifting hydraulic cylinders 704 therein are arranged in a staggered manner on the frame 11;

[0102] The ends of the right rail telescopic arm 701 and the left rail telescopic arm 702 are welded with a mounting plate and a mounting box;

[0103] The mounting plate is used to mount the hook rail mechanism 6 thereon using bolts;

[0104] A pin hole is reserved on the installation box for installation and adjustment of the walking mechanism 5;

[0105] A locking groove is provided between the telescopic arm and the frame 11. When the telescopic arm of the track shifting mechanism 7 is retracted, the telescopic arm locking mechanism 703 is manually flipped and locked into the locking groove between the telescopic arm and the frame 11 to achieve mechanical locking of the telescopic arm of the track shifting mechanism 7, thereby preventing the telescopic arm from freely extending beyond the vehicle limit of the transport rail vehicle when the hydraulic lock fails. At the same time, a visual ruler is engraved on the telescopic arm of the track shifting device 4, which is convenient for real-time observation of the track shifting amount when the telescopic arm is extended.

[0106] The hydraulic pump station 10 and the electrical control mechanism 9 are integrated and installed in an installation cabinet, and the bottom of the installation cabinet is fixedly installed on the top of the frame 11.

[0107] The outer surface of the frame 11 is fixedly mounted on the surface of the track lifting mechanism 12 , the lifting screws 8 are mounted on the top of the track lifting mechanism 12 , and the connecting plate mechanism 13 is mounted on the bottom of the track lifting mechanism 12 .

[0108] The track lifting mechanism 12 includes a guide cover 1201 , inside of which a track lifting telescopic arm 1202 and a track lifting cylinder 1203 are installed. The bottom of the track lifting telescopic arm 1202 is connected to a mounting base 1205 via a reinforcing rib 1204 .

[0109] The track lifting cylinder 1203 is fixedly installed on the inner wall of the guide cover 1201, and the output end of the track lifting cylinder 1203 is fixedly connected to the top of the track lifting telescopic arm 1202, and the outer surface of the track lifting telescopic arm 1202 is slidably connected to the inner surface of the guide cover 1201.

[0110] like Figure 5 The track lifting mechanism 12 is mainly composed of a guide cover 1201, a track lifting telescopic arm 1202, a track lifting cylinder 1203, a reinforcing rib 1204 and a mounting base 1205;

[0111] The guide cover 1201 and the frame 11 are reinforced and welded by reinforcing ribs;

[0112] The telescopic arm 1202 is reinforced and welded to the mounting base 1205 by the reinforcing rib 1204;

[0113] The guide cover 1201 and the track lifting telescopic arm 1202 are each hingedly fixed to one end of the track lifting cylinder 1203, which is a hydraulic cylinder. The telescopic movement of the track lifting telescopic arm is achieved through the action of the hydraulic cylinder, thereby achieving the lifting of the entire device and the lifting of the track after the hooking mechanism 6 hooks the rail;

[0114] An M16 lifting screw 8 is installed on the top of the guide cover 1201 to facilitate lifting and transportation.

[0115] The top of the connecting plate mechanism 13 is mounted on the bottom of the mounting base 1205 , and the surface of the connecting plate mechanism 13 is adapted to the surface of the track plate mechanism 1 .

[0116] like Figure 8 、 Figure 9 and Figure 10 The track lifting and shifting device 4 can be installed and used on three standard track plates: CRTS-Ⅰ, CRTS-Ⅱ and CRTS-Ⅲ by replacing the connecting plate;

[0117] The track plate mechanism 1 includes a first track plate 110 and a second track plate 120 , and the connecting plate mechanism 13 includes a first connecting plate 1301 and a second connecting plate 1302 .

[0118] The first connecting plate 1301 can realize the installation of the track lifting and shifting device 4 and the first track plate 110;

[0119] The second connecting plate 1302 can realize the installation of the track lifting and shifting device 4 and the second track plate 120 .

[0120] The first connecting plate 1301 and the second connecting plate 1302 are provided with bolt holes for connecting with the two mounting bases 1205 on one side of the track lifting and shifting device 4. Both are fastened with the device mounting bases 1205 using M12 bolts.

[0121] The first connecting plate 1301 and the second connecting plate 1302 have holes at their ends to connect the connecting plates to two longitudinally adjacent sleepers on the track plate. The track shifting device 4 is fixed in the gap between the two longitudinal sleepers on the track plate.

[0122] The connection between the first track plate 110 and the first connecting plate 1301 is achieved by using M30 backing bolts on the fastener mechanism 2 on the inner side of the rail on the track plate. The backing bolts are not fastener bolts.

[0123] The second track plate 120 and the second connecting plate 1302 are connected by M24 fastener bolts on the fastener mechanism 2 on the inner side of the rail on the track plate;

[0124] Since the longitudinal distance between the fasteners of CRTS-Ⅱ and CRTS-Ⅲ track plates differs by 20 mm, the end opening of the second connecting plate 1302 is a long strip hole, which can meet the installation requirements of the two types of track plates. When the first connecting plate 1301 and the second connecting plate 1302 are used, all the fastener mechanisms 2 of the sleepers on the track plates must be removed. The fasteners must be removed for track lifting, but all fastener mechanism accessories must be removed quickly on the sleepers where the track lifting and shifting device 4 is installed. Only the fasteners at other locations need to be removed to achieve seamless connection between the first connecting plate 1301 and the second connecting plate 1302 and the applicable track plates, thereby realizing seamless connection between the track lifting and shifting device 4 and the three types of track plates.

[0125] like Figure 11 , the track lifting and shifting device 4 is pushed to the appropriate point by the traveling mechanism 5, and after the device and the track plate are installed through the connecting plate mechanism 13, the traveling mechanism 5 can be removed or fixed to the lowest hole position by the latch to ensure that the supporting roller 502 of the traveling mechanism 5 does not interfere with the rail mechanism 3;

[0126] The track lifting mechanism 12 and the rail shifting mechanism 7 are operated by the electrical control mechanism and the hydraulic pump station 10 of the device, so that the rail shifting mechanism 7 is extended to both sides for a distance so that the inner side of the fixed hook 601 of the hooking mechanism 6 contacts the inner side of the rail mechanism 3;

[0127] Then manually operate to fix the movable hooks 604 of the hook rail mechanisms 6 on both sides at the hook rail positions, thereby achieving hook rail and clamp rail;

[0128] The track lifting and shifting device 4 uses a remote control or manual control to lift the rail 12 to release the fasteners to a certain distance and then operate the rail shifting mechanism 7 to push the rail to a predetermined width. Otherwise, the rail is reset.

[0129] The hydraulic pump station 10 of the track lifting and shifting device 4 is also equipped with an electric oil pump and a manual pump. The control valve can be electrically controlled or manually operated. A hydraulic lock is provided when the track lifting and shifting device 4 stops at any time to ensure the reliability of the operation.

[0130] The track lifting and shifting device 4 can achieve a maximum track lifting amount of 150mm within 4 minutes; the maximum track shifting amount on one side is 770mm within 6 minutes after reaching the track lifting height; the maximum track lifting force on one side is ≥20kN, and the maximum track shifting force on one side is ≥20kN;

[0131] Rapid track lifting and shifting can ensure that the damaged track plate is completely exposed from the rails, thereby enabling the track plate to be replaced.

[0132] The electrical control mechanism 9 uses external AC power as a power source and an AC motor as a power source, and can be controlled by a remote controller or manually.

[0133] The hydraulic pump station 10 includes a hydraulic oil tank, an operating handle, a solenoid valve, a hydraulic hose and pipeline accessories, etc., which provide a power source for raising, shifting and resetting the track. It can be controlled by manual operation or remote control.

[0134] like Figure 11 and Figure 12 When replacing one or two damaged track plate mechanisms 1, the track lifting and shifting device 4 is installed on the normal track plate mechanisms adjacent to the damaged track plate in front and behind. According to the construction process, the track lifting and shifting device 4 is installed at the pre-calibrated position on the track plate with the 100m fastener loosened. The control system controls the track lifting and shifting devices 4 at all points to achieve the track lifting and shifting amount at each position. Generally, three points are set on the left and right sides of the damaged track plate, so that the rail mechanism 3 can achieve a uniform curvature in the longitudinal height direction and the transverse horizontal direction. The curvature of the rails on the left and right sides of the damaged track plate is the largest, which can completely expose the damaged track plate. The curvature of the damaged track plate tends to decrease. At the same time, gauge rods are installed at both ends of the curvature to protect the rail mechanism 3. After the process is completed, the track lifting and shifting is carried out, and the track is re-tracked after the damaged track plate is replaced.

[0135] It enables fast track lifting and track replacement before replacing damaged high-speed railway track slabs without sawing, ensuring sufficient space for lifting and lowering the track slab crane, making the construction simple and time-saving.

[0136] Solve the problem of the free track of nearly 100 meters sliding off the track when the outer rail is super-elevated or when operating on a slope. The operation is not affected under such conditions.

[0137] The track lifting, track shifting, and track grabbing actions and devices are fixedly integrated, with high integration.

[0138] The horizontal direction uses rails for positioning, which can achieve seamless connection between movement and track shifting.

[0139] Remote control operation makes it easier to observe and operate abnormalities when a single person is working on track setting, saving manpower.

[0140] It can be operated completely manually, which is more suitable for field operations;

[0141] The lightweight design and a variety of lightweight materials are used to control the weight of the whole machine to about 250KG while meeting the track-setting indicators. At the same time, the modular design allows it to be quickly decomposed into components with a maximum weight of 40KG per module as needed, making it easy to carry in the field.

[0142] Equipped with a connecting plate as the base tooling, it can meet the needs of CRTS-Ⅰ, CRTS-Ⅱ and CRTS-Ⅲ track plates respectively. The connecting plate structure can be seamlessly connected with the sleepers and sunken rail grooves of the three types of track plates, making full use of the fastener mechanism's own bolts and mounting holes to ensure that it is firmly fixed and stable on the three types of track plates.

[0143] It can also be used in rail and sleeper replacement and other working conditions of railway engineering departments, and has a very broad market prospect.

[0144] The working method of the rapid track-lifting and shifting device for replacing ballastless track slabs of high-speed railways provided by the present invention is as follows:

[0145] The track lifting and shifting device 4 is manually pushed to a suitable position through the traveling mechanism 5 and installed between the device and the track plate through the connecting plate mechanism 13. First, the traveling mechanism 5 is removed or fixed to the lowest hole position with a pin to ensure that the support roller 502 of the traveling mechanism 5 does not interfere with the rail mechanism 3;

[0146] The track lifting mechanism 12 and the rail shifting mechanism 7 are operated by the electrical control mechanism and the hydraulic pump station 10, so that the rail shifting mechanism 7 is extended to both sides for a distance so that the inner side of the fixed hook 601 of the hooking mechanism 6 contacts the inner side of the rail mechanism 3;

[0147] Manually operate the movable hooks 604 of the hook rail mechanism 6 on both sides to be fixed in the hook rail position, thereby realizing hook rail and clamp rail;

[0148] Control the track lifting mechanism 12 to lift the rail with the fasteners loosened to a certain distance to a sufficient height, and then operate the rail pushing mechanism 7 to push the rail to a predetermined width. Otherwise, the rail will be reset.

[0149] When in use, at least 6 track lifting and shifting devices 4 are selected, with the damaged track plate as the center and 3 on each side symmetrically arranged. After the track is shifted, the damaged track plate can be completely exposed to the rail system for easy lifting;

[0150] Two of them are installed on the track plates adjacent to the damaged track plate, completely avoiding the damaged track plate;

[0151] The remaining four track lifting and shifting devices 4 are symmetrically arranged at predetermined positions on the left and right sides of the damaged track slab. The predetermined spacing is calculated based on the track stress calculated based on the fastener loosening length, construction working temperature and line curve radius in different regions.

[0152] After the six track lifting and shifting devices are installed, the track lifting mechanism controlled by the electrical system and hydraulic pump station is used to separate the rail system from the sleepers or rail grooves on the track plate, and then the two rails with the old parts loosened are shifted towards each other;

[0153] Each track lifting and shifting device 4 controls the hydraulic oil flow rate according to a preset value, so as to form an arc on the rail within the maximum stress range of the seamless rail;

[0154] The maximum rail shifting amount of the two middle track shifting devices 4 is 770mm, which gradually decreases towards the far ends, so that the damaged track plate is completely exposed, thereby achieving the purpose of replacing the damaged track plate by the horizontal track shifting method.

[0155] Compared with related technologies, the rapid track-lifting and shifting device for replacing high-speed railway ballastless track slabs provided by the present invention has the following beneficial effects:

[0156] The track lifting and shifting device 4 is an essential tool for replacing high-speed railway track plates. It is used to lift and shift the two tracks on the high-speed railway track plate with the fasteners removed at a certain distance. It can not only lift the track longitudinally, but also shift the two tracks outwards at a certain distance laterally. It is mainly used to replace the track plate mechanism 1 cast and embedded on the reinforced concrete base 14, ensuring that the rail mechanism 3 at the damaged track plate with the fasteners removed is shifted out of the damaged track plate mechanism 1, and reserving enough space to use a lifting rail car to lift out the damaged plate and lift in the new plate, thereby achieving the purpose of replacing the track plate.

[0157] Furthermore, a synchronous telescopic assembly 100 is installed on the outer surface of the frame 11, and a linkage slide 200 is installed on the output end of the synchronous telescopic assembly 100. The inner surface of the linkage slide 200 is slidingly connected to the outer surface of the frame 11, and the outer surface of the linkage slide 200 is fixedly connected to the outer surface of the guide cover 1201.

[0158] The synchronous telescopic assembly 100 includes a mounting cover 101, the outer surface of the mounting cover 101 is fixedly connected to the outer surface of the frame 11, and a driving motor 102 is installed on the surface of the mounting cover 101, and a driving gear 103 is fixedly installed on the output end of the driving motor 102, and a linkage gear plate 104 is engaged on the surface of the driving gear 103, and a telescopic slide rod 105 is fixedly installed on the surface of the linkage gear plate 104, one end of the telescopic slide rod 105 passes through the surface of the mounting cover 101 and extends to the outside of the mounting cover 101, and the surface of the telescopic slide rod 105 is slidably connected to the surface of the mounting cover 101.

[0159] There are two groups of linkage tooth plates 104, which are installed on the outer surface of the driving gear 103 from top to bottom. One group of linkage tooth plates 104 corresponds to one telescopic slide 105. The driving gear 103 is driven by the driving motor 102 to drive the linkage tooth plates 104 on both sides to retract or expand horizontally. When the linkage tooth plates 104 move, they can synchronously drive the telescopic slide 105 to move.

[0160] When the telescopic slide rod 105 moves, it is convenient to synchronously drive the linkage slide 200 to move. When the linkage slide 200 moves, it is convenient to drive the overall horizontal movement of the track lifting mechanism 12, thereby facilitating the adjustment of the position of the track lifting mechanism 12 installed on the frame 11, so as to meet the requirements of the connection plate mechanism 13 being installed at different points to meet the support of different positions on the surface of the track plate mechanism 1.

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
