[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0025] See also Figures 1 to 5 In the utility model, a scrap rail dragging device includes a supporting assembly 1, a lifting assembly 2 and a clamping assembly 3. The supporting assembly 1 includes a gantry 11 that can span the scrap rail, and a plurality of running wheels 12 installed at the bottom of the gantry 11. Through grooves 13 are provided on both sides of the gantry 11. The clamping assembly 3 is slidably arranged between the two through grooves 13 and is used to clamp the scrap rail. The lifting assembly 2 is installed between the inner top wall of the gantry 11 and the clamping assembly 3 and is used to adjust the height of the clamping assembly 3 and lift the scrap rail.

[0026] In this embodiment, preferably, the lifting assembly 2 includes two upper support arms 21, two lower support arms 22, a lower fixed plate 23 and a screw rod 24. The top ends of the two upper support arms 21 are hinged to the inner top wall of the gantry 11, and the other ends of the two upper support arms 21 are respectively hinged to one end of the two lower support arms 22, and the other ends of the two lower support arms 22 are hinged to the lower fixed plate 23. Nuts and bearings are respectively provided at the two hinges between the two upper support arms 21 and the lower support arms 22, and the screw rod 24 passes through the bearing, the nut and is threadedly connected to the nut.

[0027] In this embodiment, preferably, the two upper support arms 21 and the two lower support arms 22 have the same length and material, and the two upper support arms 21 and the two lower support arms 22 form an equilateral quadrilateral;

[0028] Specifically, the upper support arm 21 and the lower support arm 22 together form an equilateral quadrilateral, and the tension and pressure are evenly transmitted through the equilateral quadrilateral structure to ensure the vertical working state, so that the working stability is guaranteed and the service life is prevented from being reduced due to uneven force.

[0029] In this embodiment, preferably, the clamping assembly 3 includes an adjustment frame 31 slidably arranged between the two slide grooves, the adjustment frame 31 is fixedly arranged at the bottom of the lower fixed plate 23, two bidirectional screws 32 are rotatably arranged on the inner side of the adjustment frame 31, and a screw sleeve 33 is threadedly connected to the outer wall at both ends of each bidirectional screw 32, and a reinforcing connecting plate 34 is fixedly connected to the bottom of each screw sleeve 33, and a supporting block 35 is fixedly connected to one side of the reinforcing connecting plate 34;

[0030] Specifically, the threaded sleeve 33 drives the reinforcing connecting plate 34 to move through the threaded transmission of the bidirectional screw 32, thereby driving the supporting block 35 to move to the rail waist, thereby clamping the rail.

[0031] In this embodiment, preferably, one end of the two bidirectional screws 32 passes through the adjustment frame 31 and is fixedly sleeved with a sprocket 36, a chain 37 is provided between the two sprockets 36 for transmission, and the other end of one of the bidirectional screws 32 passes through the adjustment frame 31 and is fixedly sleeved with a turning handle 38;

[0032] Specifically, turning the handle 38 causes one of the bidirectional screws 32 to rotate, and at the same time, the other bidirectional screw 32 is synchronously rotated through the transmission of the sprocket 36 and the chain 37. The two sprockets 36 have the same size and diameter, and the transmission ratio is 1:1, so that the two bidirectional screws 32 can rotate synchronously and at the same speed.

[0033] In this embodiment, preferably, a plurality of through holes 14 penetrating the gantry 11 are formed on the inner bottom wall of each through slot 13, and vertical rods 39 penetrating the through holes 14 are fixedly provided on both sides of the bottom of the adjustment frame 31;

[0034] Specifically, the vertical rod 39 moves along the through hole 14 to ensure that the adjustment frame 31 moves smoothly, and after the vertical rod 39 contacts the ground, it can ensure that the gantry 11 is limited, so that the gantry 11 is stably on the ground.

[0035] In this embodiment, preferably, a screw ring 25 is fixedly provided at the end of the screw rod 24 located on one side of the bearing;

[0036] Specifically, the screw rod 24 can be conveniently controlled to rotate by twisting the ring 25 .

[0037] In this embodiment, preferably, a plurality of reinforcing rods 310 are fixedly arranged between the reinforcing connecting plates 34 on the same side;

[0038] Specifically, the reinforcing rod 310 not only increases the strength between the two reinforcing connecting plates 34, but also plays a limiting role. The bidirectional screw 32 drives the screw sleeve 33 to drive the reinforcing connecting plate 34 to move only in a straight line.

[0039] The working principle and use process of this utility model:

[0040] First, the gantry 11 is moved to the waste rail by the walking wheels 12 and straddles the waste rail. The screw rod 24 is rotated by manipulating the screw ring 25. The relative positions of the screw rod 24 and the nut change the relative positions of the upper support arm 21 and the lower support arm 22. Driven by the upper support arm 21 and the lower support arm 22, the lower fixing plate 23 moves downward in the vertical direction to push the adjustment frame 31 to move downward. The movement of the adjustment frame 31 can drive the vertical rod 39. After the vertical rod 39 moves to contact the ground, the gantry 11 can be stably placed on the ground.

[0041] Subsequently, one of the two-way screws 32 is rotated by turning the turning handle 38. At the same time, the other two-way screw 32 is synchronously rotated under the transmission of the sprocket 36 and the chain 37. The threaded transmission of the two-way screw 32 causes the screw sleeve 33 to drive the reinforcing connecting plate 34 to move, thereby driving the supporting block 35 to move to the rail waist, thereby clamping the rail.

[0042] Finally, the screw ring 25 is manipulated to rotate the screw rod 24 in the opposite direction, and the relative positions of the upper support arm 21 and the lower support arm 22 are changed again, so that the clamped scrap rail is lifted and the vertical rod 39 no longer contacts the ground, and the towing rope can be connected for towing.

[0043] In summary, the lifting assembly 2 plays a role similar to that of a jack, and the clamping assembly 3 is used to fix the scrap rails. During the entire process of dragging the scrap rails, there is no need to carry the scrap rails, which effectively solves the problem of too much manpower consumption in transportation and makes up for the defects in the prior art.

[0044] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

[0045] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
