[0002] Elevators are often installed in residential buildings for carrying people or goods. Existing elevator structures usually include a carrier box, guide rails, and guide rail mounting brackets. Among them, the carrier box is used for carrying people or goods. The carrier box is slidably mounted on the guide rails, and the guide rails are connected to the elevator shaft wall through the guide rail mounting brackets.

[0003] In order to achieve the purpose of vibration reduction, existing guide rail mounting brackets usually include a guide rail mounting part, a wall connection part, and a vibration reduction part connecting the two; after the elevator runs for a long time, if the vibration reduction part ages or the carrier box is overloaded, the vibration of the carrier box can easily cause the guide rail connecting frame to become loose, and even cause the guide rail connecting frame to fall along the elevator shaft, reducing the safety of the elevator.

[0004] Therefore, it is urgent for those skilled in the art to provide an elevator guide rail safety protection structure and a guide rail vibration reduction bracket that can reduce the risk of elevator falling and increase the safety of elevator operation. Summary of the Utility Model

[0007] A safety protection structure for a guide rail vibration reduction bracket, which is used on the guide rail vibration reduction bracket. The guide rail vibration reduction bracket includes a main housing, a guide rail connecting frame, and a vibration reduction part connecting the main housing and the guide rail connecting frame. The main housing is used for fixedly connecting with the elevator shaft wall, the guide rail connecting frame is used for fixedly connecting with the guide rail, and the vibration reduction part has a limit compression thickness D1 and a natural thickness D2; the safety protection structure of the guide rail vibration reduction bracket includes a limiting part, and the limiting part is located on the guide rail connecting frame and extends from the guide rail connecting frame towards the elevator shaft wall; there is a deformation distance H between the end face on the side of the limiting part close to the elevator shaft wall and the elevator shaft wall, and the deformation distance H satisfies: D2 - D1 < H, or, D2 - D1 < H ≤ 3mm.

[0008] Preferably, the limiting part is set as a fastener for connecting the guide rail connecting frame and the vibration reduction part.

[0009] Preferably, the central axis direction of the fastener is perpendicular to the elevator shaft wall.

[0010] Preferably, the fastener includes a bolt and a nut; from the elevator shaft wall toward the vibration damping part, the bolt penetrates the guide rail connecting frame and the vibration damping part, and is threadedly connected to the nut located on the end face of the vibration damping part away from the elevator shaft wall.

[0011] A guide rail vibration damping bracket comprises a main shell, a guide rail connecting frame, and a vibration damping part connecting the main shell and the guide rail connecting frame, wherein the main shell is used to be fixedly connected to the wall of an elevator shaft, and the guide rail connecting frame is used to be fixedly connected to the guide rail; and has a safety protection structure of the guide rail vibration damping bracket as described above.

[0012] Preferably, the guide rail connecting frame is located on the side of the vibration damping portion close to the elevator shaft wall.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] See also Figures 1 to 3, an embodiment of the present utility model provides a safety protection structure for a guide rail damping bracket, which is used on the guide rail damping bracket. Among them, the guide rail damping bracket includes a main housing 100, a guide rail connecting frame 200, and a damping part 300 connecting the main housing 100 and the guide rail connecting frame 200. The main housing 100 is fixedly connected to the wall surface of the elevator shaft, and the guide rail connecting frame 200 is fixedly connected to the guide rail.

[0027] In order to reduce the risk of elevator falling and increase the safety of elevator operation, the safety protection structure of the guide rail damping bracket includes a limiting part. The limiting part is located on the guide rail connecting frame 200 and extends from the guide rail connecting frame 200 towards the wall surface of the elevator shaft; the damping part 300 has an ultimate compression thickness D1 and a natural thickness D2; there is a deformation distance H between the end face on the side of the limiting part close to the wall surface of the elevator shaft and the wall surface of the elevator shaft, and the deformation distance H satisfies: D2 - D1 < H, or, D2 - D1 < H ≦ 3mm; through the reasonable setting of the deformation distance between one end face of the limiting part and the wall surface of the elevator shaft, on the one hand, the damping effect of the guide rail damping bracket can be avoided from being affected, and on the other hand, when the deformation of the guide rail connecting frame 200 is excessive, the end face of the limiting part can abut against the wall surface of the elevator shaft, increasing the friction force between the two, reducing the risk of the elevator falling. One end of the limiting part can even be embedded in the wall surface of the elevator shaft during the downward fall of the guide rail connecting frame 200, further increasing the resistance suffered by the downward fall of the guide rail connecting frame 200, reducing the risk of elevator falling, and increasing the safety of elevator operation.

[0028] The limiting part can be set to various structures, and when the deformation of the guide rail connecting frame 200 is excessive, it can abut against the wall surface of the elevator shaft or be stuck into the interior of the elevator shaft wall to limit the further downward fall of the elevator.

[0029] In this embodiment, the limiting part is set as a fastener 1 connecting the guide rail connecting frame 200 and the damping part 300, which can not only achieve the limiting effect, but also reduce the structure of the guide rail damping bracket, reducing the manufacturing cost and assembly difficulty of the guide rail damping bracket. Of course, in other embodiments, the limiting part can also be set as a convex block fixed on the guide rail connecting frame 200 and protruding from the guide rail connecting frame 200.

[0030] Furthermore, the fastener 1 includes a bolt 11 and a nut 12; from the wall surface of the elevator shaft towards the direction of the damping part 300, the bolt 11 penetrates through the guide rail connecting frame 200 and the damping part 300 and is threadedly connected to the nut 12 located on the end face of the damping part 300 away from the wall surface of the elevator shaft. This setting makes the head end (i.e., the end with a larger size) of the bolt 11 face the wall surface of the elevator shaft. When the deformation of the guide rail connecting frame 200 is excessive, the head end of the bolt 11 abuts against the wall surface of the elevator shaft, increasing the contact area and at the same time reducing the risk of the bolt 11 breaking.

[0031] In order to prevent the vibration of the elevator from affecting the connection strength between the guide rail connecting frame 200 and the vibration reduction part 300 of the fastener 1, in this embodiment, the central axis direction of the fastener 1 is perpendicular to the wall of the elevator shaft.

[0032] The present embodiment also provides a guide rail vibration damping bracket with the above-mentioned safety protection structure, including a main shell 100, a guide rail connecting frame 200, and a vibration damping part 300 connecting the main shell 100 and the guide rail connecting frame 200, the main shell 100 is used to be fixedly connected to the wall of the elevator shaft, and the guide rail connecting frame 200 is used to be fixedly connected to the guide rail.

[0033] In order to avoid the extension length of the limiting part (and the fastener 1) being too large, which may cause the limiting part (i.e., the fastener 1) to be easily deformed or broken when subjected to force, in this embodiment, the guide rail connecting frame 200 is located on the side of the vibration damping part 300 close to the wall of the elevator shaft, thereby reducing the extension length of the limiting part to a certain extent.

[0034] In order to facilitate the control of the size of the deformation spacing H (to facilitate data measurement during actual product manufacturing and assembly), in this embodiment, the main shell 100 has an abutment surface 101 that abuts against the wall of the elevator shaft; the abutment surface 101 is parallel to the end surface of one side of the limiting part close to the wall of the elevator shaft.

[0035] In order to increase the shock-absorbing effect without affecting the connection strength, in the present embodiment, the vibration-absorbing part 300 includes a first connecting component 301, a second connecting component 302, and a vibration-absorbing member 303 connecting the first connecting component 301 and the second connecting component 302; the first connecting component 301 is fixedly connected to the main shell 100; the second connecting component 302 is fixedly connected to the guide rail connecting frame 200 via a fastener 1.

[0036] The present application also provides a guide rail vibration damping bracket having a guide rail vibration damping bracket safety protection structure as described above, thereby being able to reduce the risk of elevator falling and increase the safety of elevator operation without affecting the vibration damping effect.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
