Description

Technical Field

[0001] This utility model relates to a heavy-duty rail lifting and moving device. Background Technology

[0002] In traditional railway maintenance, replacing heavy rails and turnouts mainly relies on manual lifting and carrying. This method is not only labor-intensive and inefficient, but also involves extremely high labor intensity and safety risks. When using mechanized operations, due to terrain conditions, the ground height on the left and right sides of the crossbeam may not be consistent. If conventional suspension equipment is used, the crossbeam cannot be placed horizontally, making suspension lifting and carrying impossible. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heavy rail lifting and moving device that is applicable to different terrains.

[0004] The technical solution adopted in this utility model is: A heavy rail lifting and handling device includes a crossbeam, a fixed support leg fixedly mounted at one end of the crossbeam, an adjustable support leg mounted at the other end of the crossbeam, and a trolley for transporting goods mounted below the crossbeam. A hoisting and traveling device is provided on the crossbeam. The adjustable support leg includes a heightening bracket, an adjusting leg mounted on the heightening bracket, and an adjusting support fixedly mounted on the crossbeam. The adjusting support cooperates with the adjusting leg.

[0005] Furthermore, the height-increasing bracket includes symmetrically arranged height-increasing connecting pipes and a support pipe disposed between the two height-increasing connecting pipes. The bottom of the adjusting leg rests on the top surface of the support pipe, and the height-increasing bracket and the adjusting leg are detachably connected by bolts.

[0006] Furthermore, the adjustable legs are symmetrically arranged in two, forming an isosceles triangle structure. An adjusting sleeve is fixedly provided at the top of the two adjustable legs, and a positioning hole is opened on the adjusting sleeve. The adjusting support is provided with several pin holes for cooperating with the positioning holes. The positioning holes and pin holes are engaged by positioning pins.

[0007] Furthermore, a transverse brace tube is provided between the bottom of the two adjustable legs.

[0008] Furthermore, a connecting plate is provided on the height-increasing bracket, and the height-increasing bracket is connected to the adjusting leg through the connecting plate.

[0009] Furthermore, the bottom surface of the adjusting leg and the bottom surface of the fixed support leg are on the same plane.

[0010] Furthermore, the hoisting traveling device is equipped with traveling wheels, which can move laterally along the top surface of the crossbeam, and an electric hoist is installed inside the hoisting traveling device.

[0011] The positive effects of this utility model are: The crossbeam of this utility model has a fixed support leg on one side and an adjustable support leg on the other side. When the terrain on both sides of the crossbeam is not horizontal, the crossbeam can be kept horizontal by adjusting the length of the adjustable support leg, thereby realizing hoisting and lifting. It is suitable for various terrain conditions such as slopes and depressions. Attached Figure Description

[0013] As attached Figure 1-3 As shown, this utility model discloses a heavy-duty rail lifting device, including a crossbeam 1 at the top, fixed support legs 2 at one end of the crossbeam 1, and adjustable support legs at the other end of the crossbeam. A lifting and traveling device 3 for lifting heavy-duty rails or turnouts is also provided on the crossbeam 1. A trolley 4 for transporting goods is located below the crossbeam 1. The trolley 4 is unpowered and is manually pushed after the goods are placed on it. The lifting and traveling device 3 has wheels and can move laterally along the top surface of the crossbeam 1, and an electric hoist is installed inside it for lifting.

[0014] The adjustable support leg includes a heightening bracket 5 located at the bottom, an adjusting leg 6 set on the heightening bracket 5, and an adjusting support 9 installed in cooperation with the adjusting leg 6. The upper end of the adjusting support 9 is fixedly connected to the crossbeam 1.

[0015] As attached Figure 3 As shown, the height-increasing bracket 5 includes two symmetrically arranged height-increasing connecting pipes and a support rod 11 disposed between the two height-increasing connecting pipes. The bottom of the adjusting leg 6 is connected to the top surface of the support rod 11. The support rod 11 serves to support the two height-increasing connecting pipes and also to support the adjusting leg 6. The height-increasing bracket 5 and the adjusting leg 6 are detachably connected by bolts. Depending on the actual terrain, it is possible to choose whether to remove the height-increasing bracket 5 so that the crossbeam 1 remains horizontal.

[0016] Two adjustable legs 6 are symmetrically arranged and tilted. An adjusting sleeve 7 is located at the top of each adjustable leg 6. The adjustable legs 6 are symmetrically arranged on the left and right sides of the adjusting sleeve 7, and an adjusting support 9 is fitted inside the adjusting sleeve 7. A positioning hole 8 is provided on the adjusting sleeve 7, and several pin holes are evenly distributed on the adjusting support 9. The height of the adjusting support 9 can be adjusted by passing the positioning pin through the positioning hole 8 and the pin holes, thereby adjusting the height of the entire adjustable leg. Preferably, a transverse support tube 13 is provided between the bottoms of the two adjustable legs 6.

[0017] A connecting plate 10 is fixedly installed on the height-increasing bracket 5, above the support rod 11, and the height-increasing bracket 5 is connected to the adjusting leg 6 through the connecting plate 10.

[0018] In this embodiment, the height-increasing bracket 5 is bent, with its lower section being vertical and its upper section having the same angle as the adjusting leg 6, so as to facilitate the connection with the adjusting leg 6. The support rod 11 is located in the upper section.

[0019] Preferably, the bottom surface of the adjustable leg 6 is on the same plane as the bottom surface of the fixed leg 2, so that it can be used not only on slopes and in depressions, but also on flat ground through adjustment.

[0020] The heightening bracket 5, adjusting leg 6, adjusting sleeve 7, adjusting support 9, support rod 11, and cross brace tube 13 are all made of square tubing, which can improve the overall stability of the device.

[0021] The adjustable support leg of this utility model achieves a three-section, two-stage adjustment form through the height-increasing bracket 5, the adjusting leg 6, and the adjusting support 9. The height adjustment of a large span can be achieved by directly removing the height-increasing bracket 5, while the cooperation between the adjusting support 9 and the adjusting sleeve 7 can achieve a smaller span but a variety of different heights, which can meet the use of different terrain conditions and keep the crossbeam 1 in a horizontal state at all times.

[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
