Description

Technical Field

[0001] This utility model relates to the field of track hoisting, and in particular to a track hoisting tool and track hoisting device. Background Technology

[0002] Currently, there are two types of rail lifting devices. One type uses a mechanical clamping mechanism, where the lifting device slides down under gravity, the clamping mechanism wraps around the rail, and when the lifting device is lifted, the clamping mechanism locks the rail head for hoisting. The other type is a simple lifting structure, which typically uses a pin-shaft connection structure to clamp the rail head for hoisting; or it uses a rail-mounted lifting device that matches the rail cross-section, installed from the end of the rail, and then moved to the lifting point for hoisting.

[0003] However, the rail-mounted lifting devices using current mechanical clamping mechanisms generally have a large lifting volume, making them unsuitable for applications with limited clearance on vehicle-mounted cantilever cranes; moreover, there is a risk of disengagement during lifting. For simple lifting structures, pin-connection structures are typically used, resulting in poor overall structural integrity, concentrated stress on the pins, and a safety hazard of metal breakage around the pins; furthermore, the rail-mounted lifting devices are cumbersome to assemble and disassemble, have poor adaptability to vertical rail lifting conditions, and are prone to scratching the rails.

[0004] Therefore, how to improve the reliability of rail-mounted lifting devices is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0033] The track lifting appliance is mainly used for lifting and moving the track 100 when the track 100 is placed transversely, especially for the track 100 with a large length, by arranging the lifting ring 1 and the envelope block 2, both ends of the lifting cavity 11 are in open structure, that is, the lifting cavity 11 only corresponds to the local position of the track 100, the bottom surface of the lifting cavity 11 is provided with the opening 12, the width of the opening 12 is greater than the rail head width of the track 100, in actual lifting, the lifting ring 1 is vertically moved, the lifting ring 1 moves from top to bottom, the lifting cavity 11 of the lifting ring 1 moves to the rail head position of the track 100, without moving the track 100; then the envelope block 2 is installed from any side of the lifting ring 1, the lifting ring 1 is lifted by the lifting part 16 at the top of the lifting ring 1, in the lifting process, the envelope block 2 is pressed between the lifting ring 1 and the track 100, the outer side surface of the envelope block 2 is clamped with the bottom of the lifting cavity 11, the inner side surface of the envelope block 2 extends from the rail head to the rail heel of the track 100 and is clamped with the rail heel, and the lifting ring 1 is continuously moved upward, so that the track 100 is lifted. The track lifting appliance has simple structure, convenient operation, can be installed at any position of the track 100, reliable lifting, and wide application range.

[0034] In some embodiments, the lifting ring 1 comprises a bottom edge 13, a side edge 14 and a limiting edge 15, the lifting cavity 11 is surrounded by the bottom edge 13, the side edge 14 and the limiting edge 15, the opening 12 is arranged on the limiting edge 15, and the envelope block 2 is placed on the side of the limiting edge 15 close to the lifting cavity 11. Specifically, the opening 12 is located at the center of the limiting edge 15, so as to ensure the symmetry of the lifting ring 1, and the limiting edge 15 can support and limit the envelope block 2, of course, the outer contour of the lifting ring 1, the internal lifting cavity 11 and the matched envelope block 2 can be other shapes.

[0035] In some embodiments, the inner side of the envelope block 2 has a profiling structure consistent with the shape of the rail head side of the rail 100, and the outer side of the envelope block 2 is adapted to the structure of the hoisting cavity 11 for mounting the envelope block 2 from both sides of the lifting ring 1; when the envelope block 2 is completely mounted and the lifting ring 1 has not been lifted, there is a certain gap between the envelope block 2 and the surface of the rail 100, and the envelope block 2 slightly swings during the movement of the lifting ring 1, thereby pressing the rail 100 and limiting the edge 15.

[0036] In some embodiments, the rail 100 is an H-shaped steel, and the envelope block 2 is a right-angled corner shape, and the envelope block 2 includes a first leg 21 and a second leg 22, and the inner side between the first leg 21 and the second leg 22 is adapted to the shape of the rail head of the rail 100; specifically, in the hoisting state, the lower part of the first leg 21 is clamped with the limiting edge 15 to prevent the envelope block 2 from being pulled out of the hoisting cavity 11, and the upper part of the first leg 21 is clamped with the rail head of the rail 100 to press the rail 100 and prevent the rail 100 from shaking during lifting, and the inner side of the second leg 22 is clamped with the rail head side of the rail 100 to prevent the rail 100 from being pulled out of the inner side of the envelope block 2.

[0038] In some embodiments, the height of the envelope block 2 is less than the height of the hoisting cavity 11, which is arranged in this way because the upper side of the envelope block 2 has a smaller clamping effect on the rail 100, so that by reducing the height of the envelope block 2, the material can be saved and the installation is facilitated; the height of the hoisting cavity 11 is less than the height of the rail 100, which is arranged in this way because the lifting ring 1 only needs to lift the rail head of the rail 100, and the height of the hoisting cavity 11 does not need to be too large, that is, the height of the lifting ring 1 does not need to be too high, thereby saving material, and when installing the lifting ring 1, the lifting ring 1 can be directly placed on the steel rail.

[0039] In some embodiments, the envelope block 2 comprises a first envelope block 2 and a second envelope block 2, the first envelope block 2 and the second envelope block 2 are identical in structure and symmetrically arranged in the hoisting cavity 11.

[0040] In some embodiments, the lifting ring 1 and the envelope block 2 are both steel structures, which have high strength and long service life. Of course, they can also be made of other materials with high strength.

[0041] In some embodiments, a chain preventing device 3 is further provided. One end of the chain preventing device 3 is connected to the envelope block 2, and the other end is connected to the lifting ring 1, which prevents the envelope block 2 from being lost, improves the disassembly and assembly efficiency, and saves costs. Specifically, the envelope block 2 and the lifting ring 1 each have a connecting hole 31, and the chain preventing device 3 is connected to the connecting holes 31 of the envelope block 2 and the lifting ring 1 respectively.

After the envelope block 2 is loaded into the hoisting cavity 11, the envelope block 2 is translated towards the first anti-falling groove 111 until the first anti-falling boss 23 is completely inserted into the first anti-falling groove 111, as shown in Figure 3 Then, the envelope block 2 is loosened, and the envelope block 2 is lowered under the action of gravity, so that the bent stop edge 23-1 is inserted into the bent clamping groove 111-1, as shown in Figure 4 In this way, the envelope block 2 can be prevented from falling out of the hoisting cavity 11.

[0043] Further, the second anti-falling groove 112 can be arranged at the bottom of the hoisting cavity 11, the bottom of the envelope block 2 is provided with a second anti-falling boss 24 matched with the second anti-falling groove 112, and the second anti-falling groove 112 and the second anti-falling boss 24 extend along the vertical direction; specifically, the second anti-falling groove 112 and the second anti-falling boss 24 extend along the vertical direction, when the bending stop edge 23-1 enters the bending clamping groove 111-1, the second anti-falling boss 24 enters the second anti-falling groove 112 at the same time, thereby further preventing the envelope block 2 from falling out of the hoisting cavity 11; of course, in the actual hoisting process, the first anti-falling boss 23 and the second anti-falling boss 24 are small in structure and do not affect the small amplitude position of the envelope block 2.
