[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1-5 As shown, this embodiment includes a base 10, on which a seat frame 20 is provided. In this embodiment, at least two seat frames 20 are provided on the base 10. The seat frame 20 is provided with a clamping assembly for clamping the rail. The base 10 is also provided with a driving assembly 40 connected to the clamping assembly and driving the clamping assembly to loosen or clamp the rail. Thus, when the rail is placed on the clamping assembly, the operation of the driving assembly 40 enables the clamping assembly to clamp the rail, and the driving assembly 40 can control the clamping force of the clamping assembly to clamp the rail.

[0027] The frame 20 is provided with rollers 21 for supporting the rails; in this embodiment, both ends of the rollers 21 are mounted on the frame 20 through bearing seats 24; thus, when the rails are placed on the rollers 21, the operation of the drive assembly 40 enables the clamping assembly to clamp the rails, and the drive assembly 40 can control the clamping force of the clamping assembly to clamp the rails.

[0028] The frame 20 includes a roller support 22 and a clamping support 23. Both ends of the roller 21 are mounted on the roller support 22 via bearing seats 24, and the clamping assembly is mounted on the clamping support 23. In this embodiment, the height of the roller support 22 is lower than the height of the clamping support 23. The total height of the roller 21 and the roller support 22 is higher than the height of the clamping support 23, so that the roller 21 can support the rail and prevent the rail from crushing the clamping assembly on the clamping support 23.

[0029] The clamping support 23 is a concave support, and the clamping assembly is disposed in the internal space of the concave support. The clamping assembly includes a hinge base 30, a left hinge block 31, and a right hinge block 32. Both the left hinge block 31 and the right hinge block 32 are hinged to the hinge base 30. A left hinge rod 33 is hinged to the end of the left hinge block 31 away from the hinge base 30, and a right hinge rod 34 is hinged to the end of the right hinge block 32 away from the hinge base 30. The left hinge rod 33... One end of the clamping support 23 passes through the left end extension and is connected to an upward-facing left clamping claw 35. One end of the right hinge rod 34 passes through the right end extension of the clamping support 23 and is connected to an upward-facing right clamping claw 36. The upper outer side of the left end extension of the clamping support 23 is provided with a left hinge seat 37 that is hinged to the left clamping claw 35. The upper outer side of the right end extension of the clamping support 23 is provided with a right hinge seat 38 that is hinged to the right clamping claw 36.

[0030] In this embodiment, the hinge seat 30 is located in the middle of the clamping support seat 23. The hinge seat 30 is a U-shaped hinge seat. One end of the left hinge block 31 and the right hinge block 32 are both located inside the U-shaped hinge seat. The hinge is achieved by passing through the left side of the U-shaped hinge seat, the left hinge block 31, the right hinge block 32 and the right side of the U-shaped hinge seat from left to right via a rotating shaft.

[0031] The left clamping jaw 35 and the right clamping jaw 36 are mirror images of each other. Both the left clamping jaw 35 and the right clamping jaw 36 include a vertical portion 35-1, an inclined portion 35-2 connected to the vertical portion, and a horizontal portion 35-3 connected to the inclined portion. In this embodiment, the inclined portion 35-2 faces the clamping support seat 23. The connection between the vertical portion 35-1 and the inclined portion 35-2 in the left clamping jaw 35 is hinged to the left hinge seat 37. The connection between the vertical portion 35-1 and the inclined portion 35-2 in the right clamping jaw 36 is hinged to the right hinge seat 38. Thus, by extending and retracting the left hinge rod 33 and the right hinge rod 34, the left clamping jaw 35 and the right clamping jaw 36 can be controlled to clamp or release the rail on the left hinge seat 37 and the right hinge seat 38.

[0032] The left hinge rod 33 is fixedly connected to the left end extension of the clamping support 23 via the first linear bearing 15, and the right hinge rod 34 is fixedly connected to the right end extension of the clamping support 23 via the second linear bearing 16. Thus, the left hinge rod 33 and the right hinge rod 34 pass through the first linear bearing 15 and the second linear bearing 16 respectively and are connected to the left clamping claw 35 and the right clamping claw 36, thereby ensuring that the left hinge rod 33 and the right hinge rod 34 can smoothly extend and retract within the first linear bearing 15 and the second linear bearing 16.

[0033] The output shaft of the drive assembly 40 passes through the clamping support 23 and is fixedly connected to the bottom of the hinge seat 30. Thus, the extension and retraction of the drive assembly 40 drives the hinge seat 30 to rise and fall. The rise and fall of the hinge seat 30 allows the left hinge block 31 and the right hinge block 32 to move closer to or further away from each other. The movement of the left hinge block 31 and the right hinge block 32 allows the left hinge rod 33 and the right hinge rod 34 to extend and retract at the left end extension of the clamping support 23. The extension and retraction of the left hinge rod 33 and the right hinge rod 34 controls the left clamping claw 35 and the right clamping claw 36 to clamp or release the rail on the left hinge seat 37 and the right hinge seat 38.

[0034] A transverse support plate 11 is provided in the middle of the base 10, so that the bottom of the drive assembly 40 is located on the transverse support plate 11; thus supporting the drive assembly 40.

[0035] The drive assembly 40 is provided with a fixed cylinder 45, which is connected to the clamping support 23 by bolts. In this embodiment, the fixed cylinder 45 is a T-shaped fixed cylinder 45. The T-shaped fixed cylinder 45 is connected to the drive assembly 40 and to the clamping support 23 by bolts, so that the output shaft of the drive assembly 40 can pass through the clamping support 23 and also provide support.

[0036] In addition, the drive assembly 40 includes a telescopic cylinder and a telescopic hydraulic cylinder.

[0037] The working principle of this utility model is as follows:

[0038] When the roller 21 is not placed with a rail, the drive assembly 40 drives the hinge seat 30 to rise, causing the left hinge block 31 and the right hinge block 32 to move closer to each other, and the left hinge rod 33 and the right hinge rod 34 to move closer to each other as well; causing the left clamping claw 35 and the right clamping claw 36 to move away from each other and open on the left hinge seat 37 and the right hinge seat 38.

[0039] When roller 21 places the rail, drive assembly 40 drives hinge seat 30 to descend, causing left hinge block 31 and right hinge block 32 to move away from each other, and left hinge rod 33 and right hinge rod 34 to also move away from each other; causing left clamping claw 35 and right clamping claw 36 to move closer to each other on left hinge seat 37 and right hinge seat 38 to clamp and press the rail, thus clamping the rail and preventing it from falling off during rail hoisting.

[0041] The difference between this embodiment and embodiment 1 is that: the seat body 10 is provided with a seat frame 20, and in this embodiment, there is one seat frame 20; a baffle is provided on one side of the seat body 10, so as to clamp the rail through the clamping assembly, and a baffle is provided at one end of the seat body 10, so as to restrict and support the rail by blocking it.

[0042] In one embodiment, the clamping assembly on the bracket 20 is capable of clamping shorter rails.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
