[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] like Figures 1 to 4 The rail transport device shown in the figure includes a first longitudinal transport roller 1, a second longitudinal transport roller 2, a first guide rail 3, a second guide rail 4, and a transverse transport roller 5 connected between the first longitudinal transport roller 1 and the second longitudinal transport roller 2. The first guide rail 3 and the second guide rail 4 are parallel to the transverse transport roller 5. A pull rail assembly 6 is slidably connected to the first guide rail 3, and a push rail assembly 7 is slidably connected to the second rail. The pull rail assembly 6 and the push rail assembly 7 are respectively arranged on one side of the first longitudinal transport roller 1 and the second longitudinal transport roller 2. There are several transverse transport rollers 5, which are arranged linearly, and the arrangement spacing is set according to the length of the track. The setting direction of the transverse transport roller 5 is perpendicular to the first longitudinal transport roller 1 and the second longitudinal transport roller 2. The conveyor roller 5 is at the same height as the first longitudinal transport roller 1 and the second longitudinal transport roller 2 when transporting the track; the track is placed on the second longitudinal transport roller 2 along the length direction for transportation. When the track moves as a whole to the transverse transport roller 5, the push-rail assembly 7 slides along the second guide rail 4 to push the track from the second longitudinal transport roller 2 to the transverse transport roller 5. When the track is transported from the transverse transport roller 5 to near the first longitudinal roller, the pull-rail assembly 6 moves in the opposite direction of movement of the transverse transport roller 5, passes through the track and fixes the track. The pull-rail assembly 6 pulls the track out of the transverse transport roller 5, so that the track is transported on the first longitudinal transport roller 1; transportation by longitudinal and transverse rollers replaces overhead crane lifting, thereby avoiding track surface quality problems caused by overhead crane loading and unloading of the track, and improving track production quality.
[0021] Specifically, such as Figures 1 to 3As shown, the rail assembly 6 includes an upper frame support column 61 slidably connected to the first rail, an upper frame 62 installed on the upper frame support column 61, and the other end of the upper frame 62 is provided with a groove structure 63 along the length direction of the upper frame 62. A rail clamp 64 is rotatably connected in the groove structure 63. The bottom of the rail clamp 64 away from one end of the upper frame support column 61 is inclined, and the rail clamp 64 is close to the top of one end of the upper frame support column 61 to form a limiting structure with the inner wall of the groove structure 63; the bottom of the rail clamp 64 is low At the height of the track, when the rail pulling assembly 6 performs the rail pulling operation, the upper frame support column 61 moves toward the track, and the bottom of the rail pulling card 64 rotates inward under the force of the track. When the rail pulling card 64 moves out of the width of the track, the upper frame support column 61 moves toward the first longitudinal transport roller 1, and the top of the rail pulling card 64 abuts against the inner wall of the groove structure 63, so that the bottom of the rail pulling card 64 cannot rotate outward, so that the bottom of the rail pulling card 64 contacts the track and forms a thrust on the track toward the first longitudinal transport roller 1, thereby achieving pulling of the track.
[0022] Specifically, such as Figure 2 、 Figure 3 As shown, the rail pull card 64 is provided with several pin holes 65 of different heights, and the rail pull card 64 is connected to the groove structure 63 by a detachable pin 66; for rails of different specifications, there are different rail heights, and pin holes 65 of different heights are provided to adapt to the pulling of rails of different heights.
[0023] Specifically, such as Figure 1 As shown, the rail pushing assembly 7 includes a rail pushing block slidably connected to the second guide rail 4, and the rail pushing block acts on the lower part of the rail. Since the center of gravity of the rail is low, the force of the rail pushing block acts on the lower part of the rail to prevent the rail from tipping over when pushing the rail.
[0024] Specifically, such as Figure 4 As shown, the transverse transport roller 5 includes a first roller groove 51, and a plurality of first rollers 52 are provided in a linear array on the first roller groove 51; the transverse transport roller 5 also includes a second roller groove 53 arranged side by side with the first roller groove 51, and a plurality of second rollers 54 are provided in a linear array on the second roller groove 53, and the second rollers 54 are staggered with the first rollers 52; the diameter of the first roller 52 is larger than that of the second roller 54, and the first rollers 52 and the second rollers 54 are tangent to the bottom of the rail, the first roller 52 is used to provide the main power source for rail transportation, and the second roller 54 is used to prevent the rail from falling into the gap of the first roller 52, thereby preventing the rail transportation from overturning.
[0025] Specifically, such as Figure 1As shown, the first longitudinal transport roller 1 and the second longitudinal transport roller 2 both include a lifting roller frame 11 and a plurality of third rollers 12 rotatably connected to the lifting roller frame 11; preferably, when the second longitudinal transport roller 2 transports the rail, the height of the second longitudinal transport roller 2 is higher than the transverse transport roller 5. When the rail needs to be transferred, the lifting roller frame 11 is lowered to the same height as the transverse transport roller 5, and the rail pushing assembly 7 is operated; during the rail pulling operation, the height of the second longitudinal transport roller 2 is lower than the transverse transport roller 5. When the rail pushing operation is completed, the lifting roller frame 11 rises to a position higher than the transverse transport roller 5 to support the rail and transport it.
[0026] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
