Among them, the use of adjective or adverbial modifiers "horizontal" and "vertical", "upper" and "lower" is only to facilitate the relative reference between multiple groups of terms, and does not describe any specific directional restrictions on the modified terms. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0041] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the present invention provides a looping hoisting device, which includes a track 1, a hoist 2, a lifting mechanism 3 and a transverse movement mechanism 4, wherein:

[0042] The track 1 comprises two parallel and spaced rails 11. Figure 3 and Figure 6 As shown, the rail 11 includes a fixed section 111 and a lifting section 112. The two fixed sections 111 are arranged opposite to each other, and the two lifting sections 112 are arranged opposite to each other. The lifting section 112 can move up and down relative to the fixed section 111. The lifting section 112 has a first working position connected to the fixed section 111 and a second working position lower than the fixed section 111. Figure 6 The lifting section 112 shown is located at the first working position. At this time, the upper end surface of the lifting section 112 is flush with the upper end surface of the fixed section 111. Figure 3 The lifting section 112 is shown to be located at the second working position. At this time, the upper end surface of the lifting section 112 is lower than the upper end surface of the fixed section 111. When in use, the lifting section 112 is set in the working area, and the fixed section 111 is set at a position adjacent to the maintenance position and fixed on the civil engineering foundation (ground) through a bracket;

[0043] The lower part of the winch 2 is connected with wheels 23 at positions corresponding to the two rails 11. The wheels 23 are arranged on the rails 11 and can reciprocate along the rails 11. The winch 2 can reciprocate along the track 1 through the wheels 23. Preferably, the length of the lifting section 112 is substantially equal to the length of the winch 2 to improve the stability of the winch 2 during operation. When the lifting section 112 is located at the first working position, the winch 2 can move to the fixed section 111 via the lifting section 112, and can move to the maintenance position (such as the maintenance position) via the fixed section 111. When the lifting section 112 is located at the second working position, due to the height difference between the fixed section 111 and the lifting section 112, the winch cannot move from the lifting section 112 to the fixed section 111.

[0044] The lifting mechanism 3 is arranged below the track 1 corresponding to the position of the lifting section 112. The bottom surface of the lifting mechanism 3 is fixed on the civil engineering foundation (ground). The lifting mechanism 3 is connected to the lifting section 112. The lifting mechanism 3 can drive the lifting section 112 to move between the first working position and the second working position. That is, the lifting section 112 can be switched between the first working position and the second working position under the drive of the lifting mechanism 3.

[0045] The transverse movement mechanism 4 is connected to the winch 2 through the connecting rod 5. The transverse movement mechanism 4 can drive the winch 2 to reciprocate along the rail 11, that is, the winch 2 can move along the rail 11 under the drive of the transverse movement mechanism 4, so as to move from the working position to the maintenance position.

[0046] When using, Figure 1 As shown, in the initial state, the lifting section 112 is located at the second working position. At this time, the winch 2 can be used normally. When maintenance is required, the lifting section 112 is first driven upward by the lifting mechanism 3 to connect the lifting section 112 with the fixed section 111, that is, the lifting section 112 is located at the first working position, and then the winch 2 is driven by the transverse mechanism 4 to move along the lifting section 112 to the fixed section 111, and then moves to the maintenance position (such as Figure 4 As shown), the winch 2 can be disassembled and maintained. After the maintenance operation of the winch 2 is completed, the transverse movement mechanism 4 drives the winch 2 to move from the fixed section 111 to the lifting section 112, and then the lifting section 112 is driven downward by the lifting mechanism 3 to make the lifting section 112 return to the second working position. At this time, the winch 2 can be used normally.

[0047] The loop hoisting device of the present invention drives the lifting section 112 to rise and fall through the lifting mechanism 3, thereby realizing the lifting and lowering of the winch 2, and drives the winch 2 to move along the track 1 through the transverse movement mechanism 4, thereby realizing the automatic movement of the winch 2 from the working position to the maintenance position and from the maintenance position to the original working position in the underground or closed space, thereby realizing the rapid disassembly and assembly of the winch 2, greatly improving the safety of the disassembly and assembly maintenance operations, and at the same time improving the operation rate of the unit. In addition, the loop hoisting device of the present invention has a simple structure and safe, reliable and stable operation.

[0048] In one embodiment of the present invention, Fig. 9 As shown, the loop winch device also includes a fixed seat 6, which is arranged below the track 1 corresponding to the position of the lifting section 112, and the bottom surface of the fixed seat 6 is fixed on the civil engineering foundation (ground). Figure 7 As shown, the winch 2 includes a bearing seat 21 and a drum 22 connected to the bearing seat 21. The specific connection method between the drum 22 and the bearing seat 21 is the existing technology and will not be repeated here. The wheel 23 is rotatably connected to the bearing seat 21 so that the wheel 23 can roll along the rail 11, thereby driving the winch 2 to move along the track 1. The bearing seat 21 is detachably connected to the fixed seat 6, and the fixed seat 6 can fix the winch 2 to ensure the stability of the winch 2 during operation. When maintenance is required, the bearing seat 21 will be separated from the fixed seat 6 and will not affect the movement of the winch 2.

[0049] Further, if Figure 8 As shown, a wheel axle 231 is connected to the wheel 23, and the wheel axle 231 can be rotatably connected to the bearing seat 21, that is, the wheel axle 231 can rotate relative to the bearing seat 21 to drive the wheel 23 to rotate synchronously, so that the wheel 23 can roll smoothly along the rail 11, wherein the wheel axle 231 and the bearing seat 21 are connected through a bearing.

[0050] Further, if Fig. 9 As shown, the bearing seat 21 is connected to the fixing seat 6 by means of bolts 61 , and the bolts 61 are easy to assemble and disassemble, thereby making the connection and separation between the fixing seat 6 and the bearing seat 21 easy and convenient.

[0051] Of course, the bearing seat 21 can also be connected to the fixing seat 6 through a pin 53 or a shear pin.

[0052] In one embodiment of the present invention, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the lifting mechanism 3 includes at least two lifting hydraulic cylinders 31, each lifting section 112 is connected to the lifting piston rod 312 of at least one lifting hydraulic cylinder 31, that is, each lifting section 112 moves up or down under the drive of at least one lifting hydraulic cylinder 31, and the lifting cylinder barrel 311 of the lifting hydraulic cylinder 31 is connected to the fixing seat 6 through a connecting bolt. The number of the lifting hydraulic cylinders 31 can be set according to actual use needs. For example, each lifting section 112 is connected to two, three or four lifting hydraulic cylinders 31. Figure 1 , Figure 2 , Figure 4 and Figure 5 In the illustrated embodiment, each lifting section 112 is respectively connected to two ends of a lifting hydraulic cylinder 31, that is, each lifting section 112 is connected to two lifting hydraulic cylinders 31 to ensure the stability of the lifting section 112 during movement, wherein when the lifting piston rod 312 is fully extended, the lifting section 112 is located in the first working position, and when the lifting piston rod 312 is fully retracted, the lifting section 112 is located in the second working position.

[0053] Of course, the lifting mechanism 3 can also be a lift or a cylinder.

[0054] Further, if Fig. 9 As shown, a bracket 32 ​​is connected to the lifting piston rod 312 of the lifting hydraulic cylinder 31, and the lifting section 112 is connected to the bracket 32. Specifically, the lifting section 112 is connected to the bracket 32 ​​through a rail clamp, and the bracket 32 ​​is connected to the lifting piston rod 312 through a fixing bolt. The setting of the bracket 32 ​​makes the connection between the lifting section 112 and the lifting piston rod 312 simple and convenient.

[0055] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the transverse movement mechanism 4 includes a transverse movement hydraulic cylinder 41, and the transverse movement piston rod 412 of the transverse movement hydraulic cylinder 41 is connected to the winch 2 through the connecting rod 5. The extension of the transverse movement piston rod 412 can drive the winch 2 to move from the lifting section 112 to the fixed section 111, and move to the maintenance position via the fixed section 111. The retraction of the transverse movement piston rod 412 can drive the winch 2 to move from the maintenance position back to the lifting section 112. The setting of the connecting rod 5 makes the connection between the transverse movement hydraulic cylinder 41 and the winch 2 simple and convenient.

[0056] Further, if Figure 1 and Figure 4 As shown, the transverse movement mechanism 4 also includes a support 42, and the transverse movement cylinder barrel 411 of the transverse movement hydraulic cylinder 41 is connected to the support 42 by connecting bolts, and the support 42 is fixed to the civil foundation (ground) by fixing bolts. The setting of the support 42 makes the placement of the transverse movement hydraulic cylinder 41 more stable, so that the transverse movement hydraulic cylinder 41 can smoothly drive the winch 2 to move along the track 1.

[0057] Further, if Fig.10 As shown, the connecting rod 5 includes a horizontal section 51 and a vertical section 52. The first end of the horizontal section 51 is connected to the winch 2, and the second end of the horizontal section 51 is connected to the first end of the vertical section 52, that is, the horizontal section 51 and the vertical section 52 have an angle of approximately 90 degrees. The second end of the vertical section 52 is provided with an oblong hole 521. The length of the oblong hole 521 is approximately the same as the up and down movement distance of the lifting section 112. A pin shaft 53 is movably arranged in the oblong hole 521. The pin shaft 53 is connected to the transverse piston rod 412 of the transverse hydraulic cylinder 41. The pin shaft 53 can move along the oblong hole 521 to ensure that the connecting rod 5 will not affect the up and down movement of the lifting section 112.

[0058] Of course, the horizontal section 51 and the vertical section 52 may also be an integrated structure, or the connecting rod 5 may be an arc-shaped rod, and the oblong hole 521 is provided at one end of the arc-shaped rod.

[0059] Going further, Figure 1 and Figure 4 As shown, a reinforcing rib 54 is connected between the horizontal section 51 and the vertical section 52. Specifically, the first end of the reinforcing rib 54 is connected to the middle of the horizontal section 51, and the second end of the reinforcing rib 54 is connected to the middle of the vertical section 52. The reinforcing rib 54 can strengthen the connection strength between the horizontal section 51 and the vertical section 52 to ensure the service life of the connecting rod 5.

[0060] The following is a detailed description of the use of the loop hoisting device of the present invention in conjunction with the accompanying drawings:

[0061] like Figure 1 As shown, when in use, in the initial state, the lifting section 112 is located in the second working position. At this time, the winch 2 can be used normally. When the winch 2 needs to be moved from the working position to the disassembly and maintenance position (maintenance position), first, the staff manually removes the bolts 61 connecting the fixed seat 6 and the bearing seat 21, and then controls the lifting piston rod 312 of the lifting hydraulic cylinder 31 to extend. The extension of the lifting piston rod 312 drives the lifting section 112 to move upward. The upward movement of the lifting section 112 will drive the winch 2 to rise and break away from the fixed base. At the same time, the pin shaft 53 moves upward relative to the oblong hole 521. When the winch 2 rises to the position with the lifting section 112, the transverse piston rod 412 of the transverse hydraulic cylinder 41 is controlled to extend until the transverse piston rod 412 is fully extended. The transverse piston rod 412 will drive the winch 2 from the working position to the disassembly and maintenance position (such as Figure 4 shown);

[0062] When the winch 2 needs to be moved from the disassembly and maintenance position to the working position, first control the transverse piston rod 412 of the transverse hydraulic cylinder 41 to retract until the transverse piston rod 412 is fully retracted, and the transverse piston rod 412 will drive the winch 2 to move from the disassembly and maintenance position to the working position through the connecting rod 5; then control the lifting piston rod 312 of the lifting hydraulic cylinder 31 to retract, and the retraction of the lifting piston rod 312 will drive the lifting section 112 to move downward, and the downward movement of the lifting section 112 will drive the winch 2 to fall back onto the fixed base. At the same time, the pin shaft 53 will move downward relative to the oblong hole 521. Finally, the staff manually connects the bearing seat 21 with the fixed seat 6 through the bolt 61 to fix the winch 2 and the fixed base together. At this time, the winch 2 can operate normally.

[0063] In summary, the looper hoisting device of the present invention has a simple structure and operates safely, reliably and stably;

[0064] The loop winch device of the present invention drives the lifting section to lift and lower through the lifting mechanism, thereby realizing the lifting and lowering of the winch, and drives the winch to move along the track through the transverse movement mechanism, thereby realizing the automatic movement of the winch from the working position to the maintenance position and from the maintenance position to the original working position in the underground or closed space, thereby realizing the rapid disassembly and assembly of the winch, greatly improving the safety of the disassembly and assembly maintenance operations, and at the same time improving the operation rate of the unit.

Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention.
