Detailed implementation mode

[0019] The embodiment is provided by Figures 1-4 This utility model includes a flat trolley body 1. The flat trolley body 1 includes a bottom plate 11. A rear seat 12, a front seat 13 and a front baffle 14 are fixedly installed on the top of the bottom plate 11 respectively. A storage table 15 is fixedly installed on the side of the front baffle 14. Support bases 16 are fixedly installed at the four corners of the bottom of the flat trolley body 1. Handles 17 are movably installed on the front and rear sides of the bottom plate 11.

[0020] Liftable universal wheels 2 are fixedly installed on the front side of the front baffle 14 and the rear of the bottom plate 11. A pull rod 5 is movably installed on the front side of the bottom plate 11.

[0021] In this embodiment, the liftable universal wheels 2 are selected with 10-inch wide tires. The load-bearing capacity of a single liftable universal wheel 2 can reach 900 kg. The combined use of four liftable universal wheels 2 can fully bear the weight of the flat trolley body 1 as a whole and four adults. The tires of the liftable universal wheels 2 are liftable. When it is necessary to move the flat trolley body 1, control the height of the tires of the liftable universal wheels 2 to be lower than the height of the support bases 16, so that the whole flat trolley body 1 is supported by the four liftable universal wheels 2. Then, the whole flat trolley body 1 can be driven to move through the provided pull rod 5, greatly increasing the convenience of the flat trolley body 1 during the moving process.

[0022] Among them, the handle 17 used in the prior art is retained and can be occasionally used in situations such as going up and down stairs and installing bottom rolling wheels.

[0023] The lifting universal wheels 2 behind the bottom plate 11 are fixedly installed on the top of the bottom plate 11 through mounting hardware 4. The lifting universal wheels 2 include a roller mounting seat 21. A silent universal wheel 22 is rotatably installed at the bottom of the roller mounting seat 21. An inner cylinder 23 is rotatably installed at the top of the roller mounting seat 21. An outer cylinder 24 is movably sleeved on the surface of the inner cylinder 23. A crank 25 is rotatably installed on the side of the outer cylinder 24. A first bevel gear 26 is fixedly sleeved at one end of the crank 25. A fixing plate 28 is fixedly installed on the inner wall of the outer cylinder 24. A second bevel gear 27 is rotatably installed on the top of the fixing plate 28. The second bevel gear 27 meshes and drives with the first bevel gear 26. A screw rod 29 is fixedly sleeved at the bottom of the second bevel gear 27. A movable sleeve 210 is fixedly installed at the top of the inner wall of the inner cylinder 23. The screw rod 29 is threadedly connected to the middle of the movable sleeve 210. A mounting base 211 is fixedly installed on the side of the outer cylinder 24. A stud is fixedly installed on the side of the mounting base 211. The mounting base 211 is fixedly connected to the mounting hardware 4 and the front baffle 14 respectively through cooperation with nuts.

[0024] In this embodiment, the mounting hardware 4 is steel right-angled and can be customized according to the height of the mounting base 211, so that the lowest point of the silent universal wheel 22 after the inner cylinder 23 fully extends is more than five centimeters lower than the support base 16, and when the inner cylinder 23 is fully retracted, it is more than one centimeter higher than the support base 16, ensuring the passability of the silent universal wheel 22 and the stability of the support base 16.

[0025] Among them, by shaking the crank 25, the first bevel gear 26 can be driven to rotate, and then the second bevel gear 27 can be driven to rotate, so that the screw rod 29 rotates. The movable sleeve 210 will lift under the rotation of the screw rod 29, thereby driving the inner cylinder 23 to extend or retract, realizing the adjustment of the height of the silent universal wheel 22.

[0026] A card seat 51 for clamping the pull rod 5 is fixedly installed on the side of the front baffle 14. A silent layer is bonded to the inner wall of the card seat 51.

[0027] In this embodiment, when the pull rod 5 is not in use, it is clamped in the card seat 51. The added silent layer can prevent noise generated by the collision between the pull rod 5 and the card seat 51. The material of the silent layer can be made of rubber, plastic foam, etc.

[0028] Second mounting grooves 19 for installing rolling wheels are opened at the four corners of the bottom plate 11. A first mounting groove 18 for mounting a driving device is opened on the surface of the bottom plate 11.

[0029] In this embodiment, before the flatbed trolley body 1 performs non-destructive testing on the rail, the front and rear rolling wheels need to be installed in the second installation groove 19 through a quick-release structure, the driving device is mounted on one side of the bottom plate 11 through the first installation groove 18, and necessary devices such as a military notebook, a wheel probe, a power supply, a 50L plastic water bucket, and some protective equipment are installed on the flatbed trolley body 1.

[0030] Working principle: By setting the liftable universal wheel 2, when it is necessary to move the flatbed trolley body 1, the silent universal wheel 22 can be shaken out, greatly increasing the convenience of the flatbed trolley body 1 during the movement process, and the existing handle 17 is retained and can be occasionally used in situations such as going up and down stairs. When the flatbed trolley body 1 is stored in the warehouse, the silent universal wheel 22 needs to be retracted, and the existing support base 16 is used for support to ensure stability.
