DETAILED DESCRIPTION

[0033] The present invention will be further described below by way of examples and in conjunction with the accompanying drawings:

[0034] like Figures 1-11 As shown, a track unloading and track laying method includes the following steps:

[0035] Step 1: Equipment Installation. After the long rail transport train has transported 400 rails to the designated location, a pair of track-laying anti-rollover devices are installed on the ground sleepers at the rear of the long rail transport train. Simultaneously, a pair of track-laying anti-rollover devices is installed at equal intervals along the forward and backward extension of the line. This application targets a 500m long rail, for which the distance between two adjacent pairs of track-laying anti-rollover devices is 25-35m.

[0036] like Figure 1-Figure 7 As shown, the track-laying anti-rollover device primarily consists of a base 600, a guide assembly 700, a flat roller assembly 800, and a vertical roller assembly 900. The base 600 is used to allow the entire track-laying anti-rollover device to be installed on two adjacent sleepers. The guide assembly 700 and the flat roller assembly 800 are positioned sequentially on the base 600, with the guide assembly 700 positioned lower in the front and higher in the back, allowing the rail 400 to move smoothly into the guide assembly 700. The flat roller assembly 800 is higher than the rear end of the guide assembly 700, allowing the rail 400 to move with the guide assembly onto the flat roller assembly 800. This drives the rollers in the flat roller assembly 800 to rotate and simultaneously elevate the rail 400, effectively increasing the distance between two adjacent track-laying anti-rollover devices. Two vertical roller assemblies 900 are positioned opposite each other between the guide assembly 700 and the flat roller assembly 800 to prevent the rail from rolling over.

[0037] The guide assembly 700 is used to ensure that the rail 400 moves to the flat roller assembly 800. The specific structure of the guide assembly 700 includes a ramp plate 710 tilted and arranged on the bottom surface with a low front and a high rear. A support plate 720 for supporting the rear end of the ramp plate 710 is arranged between the rear end of the ramp plate 710 and the base. Two side guide plates 730 are arranged on the left and right sides of the ramp plate on the base 600. The two side guide plates 730 are arranged in an "eight" shape with a large opening at the front end and a small opening at the rear end. A first reinforcing rib 740 is arranged between the side guide plate 730 and the base 600.

[0038] The flat roller assembly 800 supports the rails 400 and moves along the track. Specifically, the flat roller assembly 800 includes flat rollers 810 extending left and right. The left and right ends of the flat rollers 810 are supported by two flat roller seats 820 mounted on the base 600. To facilitate support of the flat rollers 810, grooves are provided within the flat roller seats 820 to support the left and right ends of the flat rollers 810. Each flat roller seat 820 is also equipped with a pressure plate 830 to prevent the flat rollers 810 from moving upward out of the grooves. The pressure plates 830 press the left and right ends of the flat rollers 810 within the grooves. The grooves are rectangular, corresponding to the rectangular shapes of the left and right ends of the flat rollers 810. A second reinforcing rib 840 is provided between the flat roller seats 820 and the base 600.

[0039] The specific structure of the vertical roller assembly 900 includes a vertical roller 910 extending vertically, and the vertical roller 910 is mounted on a vertical roller seat 920 via a pin, and the vertical roller seat 920 is mounted on the base 600. The vertical roller 910 and the flat roller 810 have similar structures, both including a central roller shaft and a roller sleeve mounted outside the roller shaft, and bearings are arranged between the roller sleeve and the roller shaft at both ends. Each bearing is equipped with a bearing retaining ring. The roller sleeve of the vertical roller 910 is arranged in a cylindrical shape, while the roller sleeve of the flat roller 810 is arranged in a straight middle tube with tapered surfaces at both ends. The tapered surfaces at both ends are inwardly contracted near the end, and a circular arc transition is used between the end of the tapered surface and the end face of the roller sleeve.

[0040] The base 600 specifically includes a bottom plate 610 that can be installed on two adjacent sleepers. A seat plate 630 for installing other components is provided on the bottom plate 610 through a crossbeam 620. A third reinforcing rib 640 is provided between the seat plate 630, the crossbeam 620 and the bottom plate 610. The bottom plate 610 is fixed to the sleepers through rail fasteners and bolts.

[0041] Step 2: Rail Unloading. The long rail transport train unloads the rails. First, the rail 400 is delivered from the rear of the train via the rail unloading guide device installed at the rear of the train. A rail clamp is then installed. The rail clamp is connected to the rail pulling trolley via a wire rope 500. The trolley is activated to pull the rail forward. During the pulling process, the rail 400 passes through the track-laying anti-rollover device on the ground sleeper until the trolley pulls the rail 400 to the designated unloading position, stops, and removes the rail clamp.

[0042] like Figures 8-11 As shown, the rail clamp mainly consists of a clamp body 100, an installation assembly 200 and a clamp shaft assembly 300, wherein the installation assembly 200 is arranged at the upper end of the clamp body 100, and is used to connect the wire rope 500 with the clamp device, and a rail groove 101 for the rail head 401 to extend into is provided at the lower end of the clamp body 100, and the rail groove 101 is extended forward and backward.

[0043] To facilitate the insertion of the rail head 401 and prevent it from slipping out of the rail groove 101 after insertion, a clamping shaft assembly 300 is provided on both the left and right side walls of the rail groove 101. The clamping shaft assembly 300 includes a clamping shaft 310 extending left and right. Clamping shaft holes are provided on the left and right side walls of the rail groove 101 to allow the clamping shaft 310 to move left and right. When the rail 400 is not needed for movement, the clamping shaft 310 can be retracted into the left and right side walls of the rail groove 101. When the rail 400 needs to be pulled for movement, the left and right clamping shafts 310 can be extended into the rail groove 101 and positioned below the rail head 401, thereby preventing the rail head 401 from slipping out of the rail groove 101.

[0044] To achieve the function of the clamping shaft 310, the clamping shaft assembly 300 also includes a rotating handle 320 and a stop sleeve 330. The left and right outer sides of the clamping shaft 310 are provided with handle mounting threaded holes that can be threadedly connected to the rotating handle 320, allowing a threaded connection between the clamping shaft 310 and the rotating handle 320. Stop sleeves 330 are provided on the outer sides of the left and right side walls of the rail groove 101, coaxial with the clamping shaft holes. This allows the clamping shaft 310 to pass through the stop sleeves 330 and the clamping shaft holes from the outer sides of the left and right sides, and then extend into the rail groove 101.

[0045] In order to realize that the handle 320 drives the clamping shaft 310 to move left and right and prevents the clamping shaft 310 from withdrawing, an axial groove 331 is axially provided on the stop sleeve 330 for the handle 320 to drive the clamping shaft 310 to move left and right. At the same time, a circumferential groove 332 is circumferentially provided on the stop sleeve 330 for the handle 320 to drive the clamping shaft 310 to rotate. The axial groove 331 and the circumferential groove 332 are both connected to the inner hole of the stop sleeve 330, and one end of the circumferential groove 332 is connected to the left and right side walls of the axial groove 331 close to the rail groove 101.

[0046] When the rotating handle 320 is located in the axial groove 331, the rotating handle 320 can drive the clamping shaft 310 to move left and right, so that the rail groove 101 can be accommodated on the rail head 401, and the rail head 401 can be clamped by the clamping shaft 310 that extends into the rail groove 101. When the rotating handle 320 is located in the circumferential groove 332, the rail head 401 is clamped by the clamping shaft 310. At this time, the clamping shaft 310 cannot move left and right, so the rail 400 can be pulled to move by pulling the upper end of the clamp body 100. In order to prevent the rotating handle 320 from being passively rotated into the axial groove 331 due to the rotation of the clamping shaft 310 when it is located in the circumferential groove 332, it is necessary to ensure that the circumferential groove 332 is facing one side of the wire rope 500 during installation, that is, when the rail 400 is pulled, the end of the rotating handle 320 away from the clamping shaft 310 is facing downward, such as Figure 11 shown.

[0047] During installation, the clamping shaft 310 is first retracted, and the rail groove 101 is clamped on the rail head 401. The clamping shaft 310 is then extended by rotating the handle 320 so that the clamping shaft 310 is located below the rail head 401. The rotating handle 320 is then rotated to rotate the rotating handle 320 into the circumferential groove 332 to prevent the clamping shaft 310 from moving. The wire rope 500 of the hoist is then fixed to the upper end of the clamp body 100. When the wire rope 500 is tightened, the lever formed between the clamp body 100 and the clamping shaft 310 increases friction, thereby achieving the effect of pulling the rail 400. During removal, the rotating handle 320 is rotated to return the rotating handle 320 to the axial groove 331, and then the clamping shaft 310 is withdrawn from the rail groove 101 by rotating the handle 320. The entire fixture has a simple structure. Since the clamp shaft has a telescopic function, the entire fixture can be installed from any part of the rail, thereby meeting the traction fixation requirements of different lengths and positions. At the same time, when fixing the fixture to the rail, it is only necessary to keep the clamp shaft in the extended state, making installation quick, efficient and convenient.

[0048] In order to facilitate the rotation of the rotating handle 320 , a knurling 321 for increasing friction may be provided on the rotating handle 320 .

[0049] Of course, in addition to the above-mentioned clamping shaft assembly, threaded holes can be directly provided on the left and right side walls of the rail groove 101, and at the same time, an external thread connected to the threaded hole can be provided on the clamping shaft 310. The self-locking of the thread prevents the clamping shaft 310 from extending into the rail groove 101 and then withdrawing. At this time, in order to facilitate the movement of the clamping shaft 310, a handle end can be provided at one end of the clamping shaft 310; or a pin hole for a cotter pin to pass through can be provided on the clamping shaft 310. When the clamping shaft 310 is extended into the rail groove 101, the cotter pin can be passed through the pin hole to prevent the clamping shaft 310 from moving.

[0050] To secure the wire rope 500 to the fixture, the mounting assembly 200 includes a mounting pin 210 for mounting the wire rope 500. A mounting through-hole is provided at the upper end of the fixture body 100, through which the mounting pin 210 extends left and right. Furthermore, a recessed slot 102 is provided at the upper end of the fixture body 100 to facilitate installation of the wire rope 500. To prevent the mounting pin 210 from withdrawing, a washer 220 and a cotter pin 230 are provided on the mounting pin 210 to limit its position. This allows the mounting pin 210 to be replaced as needed after extended use. The mounting assembly 200 can also be a traction hole directly provided at the upper end of the fixture body 100, or a traction member with a traction hole is installed at the upper end of the fixture body 100.

[0051] The card body 100 includes two card side panels 110 positioned opposite each other. Mounting holes are provided at the upper ends of each of the card side panels 110. To increase strength, a card sleeve 120 is provided inside the card side panels 110, with the inner hole of the sleeve 120 coaxial with the mounting holes. A card baffle 130 is provided near the lower ends of the two card side panels 110, and a fourth reinforcing rib 140 is provided on the baffle 130. The rail groove 101 is formed by the baffle 130 and the lower ends of the two card side panels 110. The card side panels 110, card sleeve 120, fourth reinforcing rib 140, card baffle 130, and stop sleeve 330 are welded together.

[0052] To ensure contact between the clamping shaft 310 and the rail head 401, one end of each clamping shaft 310 located on the left and right inner sides is set to be a frustum with a smaller inner side and a larger outer side, and the taper of the frustum matches the taper of the lower end of the rail head 401, which is used to increase the friction between the clamping shaft 310 and the rail head 401 during traction.

[0053] Step 3: Installing the rails 400. Install rail lifters on both sides of each rail 400, located in front and behind the track-laying anti-rollover device. Then, lift the rail 400 with the rail lifter, remove the corresponding track-laying anti-rollover device, and lower the rail 400 onto the sleeper using the rail lifter. After all track-laying anti-rollover devices on the corresponding rail 400 are removed in sequence, install the rail 400 until the rail 400 is completely removed. The rail lifters are conventional technology.
