Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a steel strip wound main shaft structure and elevator. Background Technology

[0002] In elevator systems, steel belts are typically wound around the car, and the car is raised or lowered by the traction of the wound steel belts.

[0003] In the current use of some elevators, the lack of a mechanism to limit the steel belt makes it easy for the steel belt to deviate during operation and winding. When the elevator is running at high speed, the deviated steel belt can easily cause elevator safety accidents.

[0004] In addition, the existing steel strip winding mechanism has poor fixation of the steel strip end. During the repeated winding and unwinding of the steel strip, it is easy to loosen, which may even affect the normal winding action of the steel strip and pose a safety hazard. Utility Model Content

[0005] To address the aforementioned issues, this application provides a structurally sound steel strip winding main shaft structure and elevator, thereby effectively ensuring the reliability, stability, and smoothness of steel strip winding and ensuring the normal and smooth lifting and lowering of the elevator.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A steel strip winding spindle structure includes a main spindle, wherein the main spindle has grooves spaced circumferentially in the middle, and baffles are detachably fitted on the main spindle on both sides of the groove edge, and the grooves and the baffles on both sides form a limiting space for winding steel strip.

[0008] As a further improvement to the above technical solution:

[0009] The baffle is an integral ring structure along the circumference, or the baffle is a ring structure assembled from two semi-ring structures or three or more arc-shaped structures; the limiting space formed by the groove and the baffles on both sides is provided at intervals of two or more along the axial direction of the main shaft.

[0010] The baffle is an annular plate structure, and the outer circumferential diameter of the baffle is 1.5-3 times the diameter of the main shaft at the mounting location.

[0011] The inner edge of the baffle extends laterally in the circumferential direction to form a flange, and the fastening bolt passes through the flange and is locked to the main shaft; the flanges on the baffles located on both sides of the same groove are arranged opposite to each other.

[0012] The main shaft located in the groove has a receiving groove for the steel strip end to be bent and inserted. The size of the receiving groove in the axial direction of the main shaft is larger than the width of the steel strip. Fasteners locked on the outside of both sides of the steel strip width press the steel strip end into the receiving groove.

[0013] The outer wall of the main shaft located in the groove is recessed to form a planar structure, and a pressure block is installed at the planar structure to form a receiving groove between the pressure block and the planar structure; the fastener passes through the pressure block and is locked into the locking hole on the planar structure.

[0014] The surface of the pressure block facing the planar structure is set as a plane, and the surface of the pressure block away from the planar structure is set as a curved surface. The curved surface and the circumferential wall of the main shaft are located on the same circumferential surface.

[0015] Two planar structures are provided around the same groove, and pressure blocks are installed at the two planar structures to form receiving grooves. The ends of the steel strip are sequentially inserted into the two receiving grooves.

[0016] The end of the fastener is lower than the surface of the pressure block, and the two ends of the pressure block with the fastener are pressed against the inner side of the corresponding baffle.

[0017] An elevator includes a steel strip wound main shaft structure as described above, wherein the main shaft is driven to rotate by a power mechanism, and the steel strip is wound and coiled within each limiting space of the main shaft.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention can guide and limit the steel strip during the winding process by using baffles, effectively ensuring the reliability, stability and smoothness of the steel strip winding; at the same time, combined with the receiving groove on the main shaft to receive and fasten the end of the steel strip, it can effectively ensure the normal and smooth lifting and lowering of the elevator.

[0020] This utility model also has the following advantages:

[0021] After the end of the steel strip is inserted into the receiving groove, the receiving groove is tightened by fasteners located on both sides of the steel strip, so that the end of the steel strip is secured. The overall structure is simple, and the end of the steel strip is easy to disassemble and assemble, allowing for quick replacement of the steel strip when needed, as well as reuse of the steel strip.

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, a steel strip winding spindle structure of this embodiment includes a main spindle 1. The main spindle 1 has grooves 11 spaced out in the middle along the circumferential direction. Baffles 4 are detachably mounted on the main spindle 1 located on both sides of the edge of the grooves 11. The grooves 11 and the baffles 4 on both sides form a limiting space for winding the steel strip 10.

[0031] In this embodiment, the baffle 4 can serve as a guide and limiter for the steel strip 10 during the winding process, effectively ensuring the reliability, stability and smoothness of the steel strip 10 winding.

[0032] In this embodiment, the groove 11 has a limited depth. In actual operation, the groove 11 positions the initial winding of the steel strip 10 on the main shaft 1. After the baffle 4 is installed, the baffle 4 limits the winding of the steel strip 10.

[0033] The baffle 4 is an integral ring structure along the circumference, or the baffle 4 is a ring structure assembled from two semi-ring structures or three or more arc-shaped structures; it can be arranged to facilitate the installation and use of the baffle 4, depending on the actual situation.

[0034] Two or more limiting spaces, consisting of groove 11 and baffles 4 on both sides, are provided at intervals along the axial direction of the main shaft 1, which are suitable for a corresponding number of steel strips 10.

[0035] The baffle 4 is an annular plate structure, and the outer circumferential diameter of the baffle 4 is 1.5-3 times the diameter of the main shaft 1 at the mounting location.

[0036] In this embodiment, the baffle 4 with a relatively large outer diameter serves two purposes: firstly, it forms a space for accommodating the coiled steel strip, limiting the coiled steel strip 10 on both sides; secondly, it provides a reliable coiling guide for the steel strip 10 before coiling, ensuring smooth and effective coiling.

[0037] The inner edge of the baffle 4 extends laterally in the circumferential direction to form a flange 41. The fastening bolt passes through the flange 41 and is locked to the main shaft 1. The flanges 41 on both sides of the baffle 4 located in the same groove 11 are arranged opposite to each other.

[0038] In this embodiment, the flange 41 effectively ensures the installation reliability of the baffle 4 on the main shaft 1; the flange 41 can also press the two ends of the pressure block 2 into the inner side to ensure reliable positioning of the steel strip 10 end.

[0039] like Figure 3 and Figure 4 As shown, a receiving groove 5 is provided on the main shaft 1 located at the groove 11 for the end of the steel strip 10 to be bent and inserted. The size of the receiving groove 5 in the axial direction of the main shaft 1 is larger than the width of the steel strip 10. The end of the steel strip 10 is pressed into the receiving groove 5 by fasteners 3 locked on the outside of both sides of the width of the steel strip 10.

[0040] In this embodiment, after the end of the steel strip 10 is inserted into the receiving groove 5, the receiving groove 5 is tightened by the fasteners 3 located on both sides of the steel strip 10, so that the end of the steel strip 10 is fastened. The overall structure is simple, and the end of the steel strip 10 is easy to disassemble and assemble. The steel strip 10 can be quickly replaced when needed, and the steel strip 10 can be reused.

[0041] In this embodiment, the fasteners 3 on both sides are used to tighten the receiving groove 5 to fix and restrict the end of the steel strip 10, which is different from the installation method in the prior art where the fasteners are directly inserted and locked to the end of the steel strip 10.

[0042] like Figure 5 and Figure 6 As shown, a planar structure 12 is formed by recessing the outer wall of the main shaft 1 located at the groove 11. A pressure block 2 is installed at the planar structure 12, and a receiving groove 5 is formed between the pressure block 2 and the planar structure 12. The fastener 3 passes through the pressure block 2 and is locked into the locking hole 13 on the planar structure 12.

[0043] In this embodiment, the pressing block 2, which is independent of the main shaft 1, and the planar structure 12 are assembled to form the receiving groove 5 for pressing the steel strip 10, which facilitates the limiting installation operation of the end of the steel strip 10 in actual practice.

[0044] Of course, in practice, the receiving groove 5 can also be machined directly on the main shaft 1 to allow the steel strip 10 to be inserted and the fastener 3 to be tightened.

[0045] The surface of the pressure block 2 facing the planar structure 12 is set as a plane, and the surface of the pressure block 2 away from the planar structure 12 is set as a curved surface. The curved surface and the circumferential wall of the main shaft 1 are located on the same circumferential surface.

[0046] In this embodiment, the pressure block 2 and the main shaft 1 form a split shaft, and their outer circumferences are located on the same circumferential surface, which ensures the effect of the steel strip 10 after winding.

[0047] Two planar structures 12 are arranged around the same groove 11, and pressure blocks 2 are respectively installed at the two planar structures 12 to form receiving grooves 5. The ends of the steel strip 10 are sequentially inserted into the two receiving grooves 5.

[0048] In this embodiment, the two receiving grooves 5 are provided so that the end of the steel strip 10 is pressed and fixed twice in succession, which effectively ensures the reliability of the fixation of the end of the steel strip 10.

[0049] In this embodiment, the two planar structures 12 in the circumferential direction of the same groove 11 can be set to be parallel to each other. While ensuring reliable fixation of the end of the steel strip 10 by double clamping, the bending angle of the steel strip 10 is effectively reduced, which helps to ensure the smooth transition of the overall winding of the steel strip 10.

[0050] The end of the fastener 3 is lower than the surface of the pressure block 2 to avoid affecting the winding of the steel strip 10 by the fastener 3; the two ends of the pressure block 2, which is locked with the fastener 3, are pressed into the inner side of the corresponding baffle 4 to further ensure the reliability of the pressing of the end of the steel strip 10.

[0051] The fixing and winding method of the steel strip 10 in this utility model is as follows:

[0052] like Figure 4 As shown, the end of the steel strip 10 is attached to one of the planar structures 12, and a fixing block 2 is installed on the planar structure 12 by fastener 3; force is applied to the steel strip 10, so that it bends and attaches to the circumference of the main shaft 1 after passing through the planar structure 12, and wraps around to the other planar structure 12, and is attached to the planar structure 12, and the fixing block 2 is locked by fastener 3, thus completing the installation of the two fixing blocks 2 on the main shaft 1, and completing the end fixing of the steel strip 10;

[0053] Force is applied to the steel strip 10 to bend it and make it fit against the circumferential surface of the main shaft 1 and the outer wall of the pressure block 2, and then it is wound layer by layer. After the steel strip 10 is wound two turns, the baffles 4 on both sides of the steel strip 10 are installed. After the baffles 4 are installed, the steel strip 10 can be wound or released normally.

[0054] This embodiment also proposes an elevator, including the steel strip winding main shaft structure of any of the above, wherein the main shaft 1 is driven to rotate by a power mechanism, and the steel strip 10 is wound and rolled within each limiting space of the main shaft 1.

[0055] In this embodiment, the two ends of the main shaft 1 located on both sides of the steel strip 10 are supported by corresponding brackets, which effectively ensures the structural stability of the main shaft 1 when it is driven by the power mechanism to perform the winding action of the steel strip 10.

[0056] This invention effectively ensures the reliability, stability, and smoothness of steel strip winding, effectively guarantees the normal and smooth lifting and lowering of elevators, and ensures safe use.

[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0058] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
