[0002] In a loose-laying operation environment where mechanical track laying is not possible, a 25m long rail needs to be transported to the work surface for on-site construction, and a transport vehicle is required to transport the rails. The existing transport frame includes a bent rod, a connecting frame, a running wheel, and a clamp for clamping the rails. The clamp includes a connecting bolt connected to the connecting rod and a pair of grabbing hooks connected to the connecting bolt by fasteners. The grabbing hooks form a clamping space for accommodating the rails. The two grabbing hooks are connected to both sides of the connecting bolt by bolts. The upper part of the connecting bolt is connected to the connecting rod by a rotating shaft. When clamping the rails, the bent rod needs to be lifted and lowered, which can easily cause the transport frame to tip over. The groove of the grabbing hook is set horizontally, and there is a gap between the grabbing hook and the side wall of the rail when clamping the rail. The rails are easily displaced during the movement of the transport vehicle, causing the risk of the rails falling off. Therefore, it is necessary to design a transport frame that can fasten the rails and is not easy to tip over. Utility Model Content

When the vehicle is to be transported to another place, the lifting mechanism 3 is lifted up and the vehicle is to be transported to another place by the lifting mechanism 3. When the vehicle is to be transported to another place, the lifting mechanism 3 is lifted up and the vehicle is to be transported to another place by the lifting mechanism 3.

[0028] The shipping trolley of the present application is used in conjunction with a forklift, one end of the rail 8 is fixed on the forklift, and the other end is fixed to the bottom of the shipping trolley. The forklift provides power to drive the shipping trolley to transport the rail 8 to the construction site, thereby increasing the speed of the shipping trolley in shipping the rail. The universal wheel set 1 on the shipping trolley enables the shipping trolley to cooperate with the forklift to realize turning movements. At the same time, the clamping mechanism 4 of the shipping trolley is arranged on the lower side of the supporting mechanism 2, so as to achieve the purpose of placing the rail on the bottom of the shipping trolley for shipping, reduce the use of lifting procedures, and improve the safety of construction. Moreover, the clamping mechanism 4 includes a rail clamp 5 and a fastener 6. Through the cooperation of the rail clamp 5 and the fastener 6, the tightness of the clamping mechanism 4 on the rail 8 is improved.

[0029] In this embodiment, the universal wheel group 1 is installed on the lower side of the supporting mechanism 2 to facilitate driving the supporting mechanism 2 to move forward, backward, turn left or right, and the lifting mechanism 3 drives the clamping mechanism 4 to move upward or downward. When the clamping mechanism 4 clamps the rail 8, the trolley moves along the length direction of the rail 8 to a position 3m away from the end of the rail 8, and the lifting mechanism 3 is started. The lifting mechanism 3 drives the clamping mechanism 4 to move downward so that the top of the clamping space 7 contacts the top of the rail 8, and the lifting mechanism 3 stops working. Then, fasteners 6 are inserted into both sides of the rail 8 to clamp the fasteners 6 and the rail clamp 5. The fasteners 6 are a rail waist imitation structure. After the fasteners 6 are clamped into the rail clamp 5, the top of the fasteners 6 is in close contact with the lower side of the rail head of the rail 8, and the fasteners 6 are away from the rail clamp. When the rail 8 is at the bottom, the lifting mechanism 3 is started, and the lifting mechanism 3 drives the clamping mechanism 4 and the rail 8 to move upward, so that there is a distance between the rail 8 and the ground. After the lifting mechanism 3 drives the clamping mechanism 4 to rise to the target height, the lifting mechanism 3 stops working. After the rail 8 arrives at the construction site, the clamping mechanism 4 releases the rail 8. The lifting mechanism 3 is started first, and the lifting mechanism 3 drives the clamping mechanism 4 and the rail 8 to move downward. When the bottom of the rail 8 contacts the ground, the lifting mechanism 3 stops working. Then the fastener 6 is taken out and the lifting mechanism 3 is started again. The lifting mechanism 3 drives the rail clamp 5 to move upward to the target height. The rail clamp 5 is separated from the rail 8, and one rail transportation is completed.

[0030] Furthermore, gaskets are provided along the side walls of the clamping space 7 to prevent the rail 8 from being worn when the rail clamp 5 contacts the rail 8 .

[0031] like Figure 1 and Figure 2 As shown, grooves 9 are provided on the inner side walls facing each other of the rail clamp 5. The two grooves 9 are of the same size and located at the same height. The fastener 6 is an L-shaped structure. The lateral end of the fastener 6 matches the size of the groove 9 to facilitate clamping the fastener 6 and the rail clamp 5.

[0032] In this embodiment, the groove 9 is arranged along the width direction of the rail clamp 5, and the groove 9 is a square structure. The length of the lateral end of the fastener 6 is consistent with the length of the groove 9, the width of the lateral end of the fastener 6 is consistent with the width of the groove 9, and the height of the lateral end of the fastener 6 is consistent with the height of the groove 9. The lateral end of the fastener 6 fills the groove 9. Under the joint action of the rail clamp 5 and the rail 8, the position of the fastener 6 is fixed, and the fasteners 6 on the left and right sides of the rail 8 clamp the rail 8.

[0033] Furthermore, a rubber pad is provided on the inner side of the groove 9 to increase the friction between the groove 9 and the lateral end of the fastener 6 , thereby preventing the fastener 6 from escaping from the groove 9 and causing the rail 8 to fall off.

[0034] In another possible embodiment, the fastener 6 is wedge-fitted with the groove 9 .

[0035] like Figure 1 and Figure 2 As shown, the fastener 6 is a fastening bevel iron, and threaded holes 10 are provided on the side walls on both sides of the rail clamp 5. The aperture of the threaded hole 10 matches the aperture of the fastening bolt 11. After the fastening bolt 11 passes through the threaded hole 10, it is tightened against the fastener 6.

[0036] In this embodiment, the threaded hole 10 is arranged horizontally, and the fastening bolt 11 passes through the threaded hole 10 and is tightened against the side wall of the fastener 6 to prevent the fastener 6 from escaping from the groove 9, while improving the tightening strength between the fastener 6 and the rail 8.

[0037] like Figure 3 As shown, the support mechanism 2 includes a support steel plate 12, a limit plate 13 and a support 14. The support steel plate 12 is a square steel plate. The support 14 is installed in the middle of the upper side of the support steel plate 12. The limit plate 13 is installed in the middle of the lower side of the support steel plate 12. There are two limit plates 13 and they are both L-shaped plates. The two limit plates 13 are arranged facing each other along the width direction of the support steel plate 12. The horizontal ends of the two limit plates 13 are both threadedly connected to the support steel plate 12. The vertical ends of the limit plates 13 are perpendicular to the support steel plate 12 and extend downward to facilitate limiting the rise of the rail 8.

[0038] In this embodiment, a rectangular hole is provided in the middle of the supporting steel plate 12, the long side of the rectangular hole is arranged along the width direction of the supporting steel plate 12, and the short side of the rectangular hole is arranged along the length direction of the supporting steel plate 12. The length of the rectangular hole is 153 mm and the width is 88 mm. The spiral rod of the lifting mechanism 3 passes downward through the rectangular hole and is connected to the top of the rail clamp 5. A limit plate 13 is welded at both ends along the length direction of the rectangular hole. The vertical end of the limit plate 13 is vertically downward, and the length direction of the vertical end of the limit plate 13 is perpendicular to the length direction of the rail 8, so that the rising height of the rail 8 can be limited by the limit plate 13.

[0039] Furthermore, a handle is provided on the supporting steel plate 12, and the transport vehicle is pushed to move by the handle.

[0040] like Figure 3 As shown, the support 14 includes a first support plate 15 and a second support plate 16. The first support plate 15 and the second support plate 16 have the same structure and are both Z-shaped plates. The first support plate 15 and the second support plate 16 are arranged opposite to each other along the width direction of the supporting steel plate 12. The bottoms of the first support plate 15 and the second support plate 16 are both threadedly connected to the supporting steel plate 12, and the tops of the first support plate 15 and the second support plate 16 are both threadedly connected to the base of the lifting mechanism 3.

[0041] In this embodiment, the support 14 is used to support and fix the lifting mechanism 3. The length of the first support plate 15 is 88 mm and the height is 85 mm. The width of the top extension plate and the bottom extension plate of the first support plate 15 are both 10 mm. The bottom extension plate of the first support plate 15 is located outside the short side of the rectangular hole of the supporting steel plate 12 and is threadedly connected to the supporting steel plate 12 by bolts. The top extension plate of the first support plate 15 extends toward the inside of the rectangular hole. The second support plate 16 is the same size as the first support plate 15 and is positioned opposite to it. The top extension plate of the first support plate 15 and the top extension plate of the second support plate 16 are threadedly connected to the base of the lifting mechanism 3 by bolts; the rail clamp 5 rises along the height direction of the first support plate 15 and the second support plate 16 under the drive of the lifting mechanism 3. The extension plates on the top of the first support plate 15 and the second support plate 16 are used to limit the rising height of the rail clamp 5.

[0042] The universal wheel assembly includes a first universal wheel 17 and a second universal wheel 18 . The first universal wheel 17 and the second universal wheel 18 are respectively mounted on the left and right ends of the supporting steel plate 12 along the length direction.

[0043] In this embodiment, the first universal wheel 17 and the second universal wheel 18 enable the shipping vehicle to move forward, backward, turn left and turn right.

[0044] A rubber structure is provided on one side of the fastener 6 close to the rail 8 .

[0045] In this embodiment, a rubber pad is provided on the side of the fastener 6 close to the rail 8 to prevent the fastener 6 from causing wear on the rail 8 when inserted into the groove 9. At the same time, the rubber pad can also increase the friction between the fastener 6 and the rail 8, thereby improving the supporting strength of the fastener 6 on the rail 8.

[0046] The lifting mechanism 3 is a screw screw lift.

[0047] The screw rod lift uses the SWL2.5T model.

[0048] When in use, one end of the rail 8 is fastened to the forklift, and the transport vehicle is pushed along the length direction of the rail 8 to 3m away from the other end of the rail 8, and the lifting mechanism 3 is started. The lifting mechanism 3 drives the rail clamp 5 to move downward, so that the rail clamp 5 moves from the top of the rail 8 to the rail waist position. At this time, the rail 8 is located in the clamping space 7, and the lifting mechanism 3 stops working. The fasteners 6 are inserted into the grooves 9 facing the rail clamp 5 at the same time. The two fasteners 6 clamp the rail 8, and the fastening bolts 11 are screwed into the threaded holes 10 on the left and right sides of the rail clamp 5. The fastening bolts 11 pass through the threaded holes 10 and are tightened with the fasteners 6. At this time, the two sides of the fastener 6 are respectively tightened with the rail 8 and the fastening bolts 11, and the fastening of the rail 8 is achieved by the fastener 6, and the lifting mechanism 3 is started again. The lifting mechanism 3 is activated, and the lifting mechanism 3 drives the rail 8 to move upward. When the rail 8 contacts the vertical end of the limit plate 13, the lifting mechanism 3 stops working, and the consignor car cooperates with the forklift to transport the rail 8 to the construction site. The first universal wheel 17 and the second universal wheel 18 cooperate with the forklift to enable the consignor car to pass the curve smoothly. After the rail 8 arrives at the construction site, the lifting mechanism 3 is started, and the lifting mechanism 3 drives the rail 8 to the ground. After the lifting mechanism 3 stops working, the fastening bolt 11 is screwed out and the fastener 6 is taken out. The lifting mechanism 3 is started again, and the lifting mechanism 3 drives the rail clamp 5 to rise to the rectangular hole. The rail clamp 5 is separated from the rail 8 and the consignor car is pushed out of the rail 8. At this point, the consignor car completes the consignment task of the rail 8. This is repeated until the rail transportation is completed. The present application clamps the rail 8 by two fasteners 6, which improves the safety of the rail 8 transportation and avoids displacement of the rail 8 and the fastener 6. The fastener 6 is detachably connected to the rail clamp 5, which improves the applicability of the rail clamp 5.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural transformation made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
