[0034] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0038] See Figures 1 to Figure 3 , is a top pull rope wheel installation protection structure shown in an embodiment of the present application, specifically involving the structural design of the top pull rope wheel 10a installation and safety protection. Exemplarily, the installation structure involved includes a rope wheel base 10, a shock absorbing assembly 20 and a top support structure 30.

[0039] like Figure 6 and Figure 7 As shown, an upper pulley 10a is installed on the pulley base 10, and a rope groove is provided on the circumferential surface of the upper pulley 10a, and the rope groove is used for winding the wire rope. After the upper pulley 10a and the pulley base 10 are installed, they act as a fixed pulley, which only serves to rotate and guide the wire rope to slide, and cannot translate or rotate as a whole.

[0040] Optionally, the rope pulley base 10 is composed of two L-shaped metal blocks, and the cavity formed in the middle is used to install the pulley 10a and its rotating shaft, so that the assembly and disassembly of the pulley 10a is more convenient and labor-saving.

[0041] The shock absorbing assembly 20 comprises a first rigid component, a shock absorbing member and a second rigid component. The shock absorbing member is connected between the first rigid component and the second rigid component. The first rigid component is connected to the rope pulley base 10; and the top supporting structure 30 is connected to the second rigid component.

[0042] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: in the installation and protection structure of the top pulley of this solution, the pulley base 10 is connected to the first rigid component, and the second rigid component is connected to the top supporting structure 30, that is, the top pulley 10a (composed of the pulley 10a and the pulley base 10) is installed on the top supporting structure 30 preset on the building through the shock absorbing assembly 20. At this time, even if the car generates vibration during operation, the vibration is transmitted to the shock absorbing component through the pulley base 10 and the first rigid component, and the shock absorbing component can weaken the vibration or even eliminate the vibration, thereby preventing the vibration from being further transmitted to the building through the second rigid component and the top supporting structure 30, avoiding vibration or noise to the building, which is not only beneficial to protecting the structural safety of the building, but also can create a quieter and more comfortable activity environment in the building, avoiding adverse effects on people in the building.

[0043] Please continue to refer to Figures 1 to Figure 3 In some optional embodiments, the installation protection structure of the top pulley further includes at least one first bolt assembly 40 and at least one second bolt assembly 50, the first rigid component is set as the first steel plate 21, the shock absorbing component is set as the shock absorbing rubber 22, and the second rigid component is set as the second steel plate 23. The first steel plate 21, the shock absorbing rubber 22 and the second steel plate 23 are used as specific accessories, which are easy to obtain, have good structural strength, strong elastic shock absorbing ability, and good use effect.

[0044] The sheave base 10 is fixedly locked with the first steel plate 21 by at least one first bolt assembly 40, and the second steel plate 23 is fixedly locked with the top support structure 30 by at least one second bolt assembly 50. The bolt-locked installation structure is simple in installation and easy to assemble and disassemble, and can ensure that the sheave base 10 and the first steel plate 21, as well as the second steel plate 23 and the top support structure 30, obtain excellent connection reliability.

[0045] Of course, in other optional embodiments, the rope pulley base 10 and the first steel plate 21 as well as the second steel plate 23 and the top supporting structure 30 may be assembled and fixed by welding, riveting, bonding, snap-fit ​​connection, etc., which can be flexibly selected according to actual needs.

[0046] In order to reduce the number of parts, reduce the difficulty of installation and improve the installation efficiency, and at the same time enable the shock-absorbing assembly 20 to obtain better overall structural performance, in some embodiments, the first steel plate 21 is glued and fixed to one side of the thickness direction of the shock-absorbing rubber 22 by a first adhesive, and the second steel plate 23 is glued and fixed to the other side of the thickness direction of the shock-absorbing rubber 22 by a second adhesive.

[0047] For example, the first adhesive member and the second adhesive member may be, but are not limited to, any one of glue, double-sided tape, etc., or a combination of at least two or more thereof.

[0048] Alternatively, hot melt bonding can be used, by heating the two side surfaces of the shock-absorbing rubber 22 in the thickness direction to melt the surface rubber and then bond the first steel plate 21 and the second steel plate 23 respectively, and after cooling and solidifying, the three can be bonded into an integrated structure.

[0049] Considering that in actual use, due to the influence of factors such as aging of the shock-absorbing rubber 22, there is a risk of the first steel plate 21, the shock-absorbing rubber 22 and the second steel plate 23 being disengaged, the present application further adopts the design of a redundant installation structure. That is, in one embodiment, the installation protection structure of the top pull rope wheel also includes at least one third bolt assembly 60, and the installation protection structure of the top pull rope wheel is also provided with at least one through hole penetrating the rope wheel base 10, the first steel plate 21, the shock-absorbing rubber 22, the second steel plate 23 and the top supporting structure 30, and the third bolt assembly 60 is installed in the corresponding through hole.

[0050] In this way, the rope pulley base 10, the first steel plate 21, the shock-absorbing rubber 22, the second steel plate 23 and the top supporting structure 30 are rigidly connected by bolts through the third bolt assembly 60 to form a redundant mounting structure. The setting of the redundant mounting structure can effectively prevent the top pulley 10a from falling after the shock-absorbing rubber 22 is torn due to its own gravity during the initial stage of elevator installation (before hanging the wire rope), when the wire rope is replaced in the later stage of the elevator, or when the elevator is in an emergency or severe working condition, thereby ensuring safety.

[0051] It is necessary to explain that the bolts in the redundant installation structure are only semi-tightened (because the connected parts include the soft component of the shock-absorbing rubber 22, the bolts cannot be fully tightened). Moreover, the bolts of the redundant installation structure can only be tightened after the wire rope is hung and loaded (that is, the shock-absorbing rubber 22 of the top pulley 10a is compressed), and can only be semi-tightened (one of the tightening methods is: tighten until the spring washer is flattened), and can be prevented from loosening by setting a double nut structure.

[0052] Please continue reading Figures 4 to 5 In addition, based on any of the above embodiments, the installation protection structure of the top pull rope pulley further includes a guard mechanism 70, which is installed on the pulley base 10 and surrounds the outer periphery of the pull rope pulley 10a on the pulley base 10. On the one hand, the provision of the guard mechanism 70 can prevent the steel wire rope from falling off the pull rope pulley 10a and being thrown out to cause damage to the car top operator, and on the other hand, the pull rope pulley 10a in a rotating state can also cause damage to the car top operator.

[0053] Specifically, in some optional embodiments, the shielding mechanism 70 includes a shielding side plate 71, which is disposed on the rope pulley base 10 and is located on one axial side of the pull-up rope pulley 10a. The shielding side plate 71 can form a lateral shield to separate the pull-up rope pulley 10a from the operator on the car top to prevent the rotating pull-up rope pulley 10a from injuring the operator. The shielding side plate 71 and the rope pulley base 10 can be installed in a manner including but not limited to at least one of screw connection, snap connection, welding, bonding, magnetic connection, etc.

[0054] Please continue reading Figure 7 Furthermore, the shielding mechanism 70 further includes a circumferential shielding plate 72, which is connected to the periphery of the shielding side plate 71 and is arranged around the outer periphery of the pull rope wheel 10a. At this time, the axial shielding plate cooperates with the shielding side plate 71 to form a closed-loop protection structure, which can achieve a more complete enclosure of the pull rope wheel 10a.

[0055] The side guard plate 71 and / or the circumferential guard plate 72 are provided with a protective portion 75 and / or a warning portion 74. For example, the protective portion 75 is chamfered or rounded to prevent the operator from being stabbed or scratched when accidentally touched. The warning portion 74 can be yellow and black stripes, which can effectively warn the operator to pay attention to the arrangement of the top pull rope wheel 10a installed at a relatively low position, so as to prevent the occurrence of squeezing accidents during the upward maintenance.

[0056] Figure 4 and Figure 5 In the embodiment shown, the difference is that when the guard portion 75 is chamfered, Figure 4 The chamfer in the middle extends to the anti-jump board 73 at the bottom, and Figure 5 The chamfer in the middle does not extend to the lower anti-jump plate 73. Figure 5 In terms of Figure 4 The design avoids the existence of exposed chamfered corners, eliminating the risk of potential harm to workers on the car roof.

[0057] Furthermore, the guarding mechanism 70 further includes an anti-jumping plate 73, one end of which is connected to the rope pulley base 10, and the other end of which is connected to the guarding side plate 71, and the main part of the anti-jumping plate 73 is enclosed at the periphery of the pull-up rope pulley 10a. Preferably, at least two anti-jumping plates 73 are provided, and at least two anti-jumping plates 73 are enclosed at the periphery of the pull-up rope pulley 10a. The strength of the anti-jumping structure can be strengthened, the anti-jumping performance can be increased, and in extreme cases, even if the wire rope jumps out of the rope groove, it can always be wound around the rope pulley shaft, thereby preventing serious installation accidents caused by the wire rope completely detaching from the rope pulley.

[0058] In addition to the above, the present application also provides an elevator, which includes the installation and protection structure of the top pulley as described in any of the above embodiments.

[0059] For example, the elevator may specifically be a machine room-less elevator.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
