[0026] 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.

[0028] 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.
[0029] See also Figures 1 to 5 The embodiment of the utility model provides an anti-separation structure of an elevator guide rail vibration-damping bracket, which is used to connect a guide rail connecting frame 100 and an elevator shaft wall mounting frame 200, and includes a first connecting portion 1, a second connecting portion 2 and a vibration-damping portion 3; the first connecting portion 1 is used to be fixedly connected to the elevator shaft wall mounting frame 200, and the second connecting portion 2 is used to be fixedly connected to the guide rail connecting frame 100, the first connecting portion 1 and the second connecting portion 2 are connected through the vibration-damping portion 3, and an anti-contact gap 4 is provided between the first connecting portion 1 and the second connecting portion 2; the first connecting portion 1 has a supporting surface, and the projection of the second connecting portion 2 on the plane where the supporting surface is located partially coincides with the supporting surface (see Figure 2 , the two projections form an overlapping area 300) to limit the moving distance of the second connecting part 2 relative to the first connecting part 1 in the direction of gravity.
[0030] It is worth noting that when the anti-separation structure is in normal working state (i.e., it can play a vibration reduction effect), there is an anti-contact gap 4 between the first connection part 1 and the second connection part 2. At this time, the first connection part 1 and the second connection part 2 are connected only by the vibration reduction part 3 to ensure the vibration reduction effect of the anti-separation structure. When the elevator fails (such as aging of the vibration reduction part 3, elevator overload, etc.), at this time, along the direction of gravity, the abutment surface of the first connection part 1 can support the second connection part 2 to reduce the risk of the elevator falling.
[0031] There are various structures and matching modes of the first connection part 1 and the second connection part 2, which can make the anti-separation structure have a vibration reduction effect when the elevator is working normally, and can prevent the elevator from falling when the elevator fails.
[0032] In this embodiment, the second connecting part 2 includes a second pressure plate 21 and two second connecting plates 22 fixedly connected to the second pressure plate 21. The second pressure plate 21 is connected to the vibration damping part 3. The second connecting plate 22 is used to be fixedly connected to the guide rail connecting frame 100. Along the running direction of the elevator (i.e., in the direction parallel to gravity), one of the two second connecting plates 22 is located on the upper side of the first connecting part 1, and the other is located on the lower side of the first connecting part 1. Correspondingly, both the upper and lower sides of the first connecting part 1 have support surfaces, so that the support surfaces can limit the second connecting part 2 from separating from the first connecting part 1 along the running direction of the elevator. On the one hand, when the second connecting plate 22 located on the upper side abuts against the supporting surface on the upper side of the first connecting part 1, the elevator can be prevented from falling. On the other hand, during the installation of the anti-separation structure of the elevator guide rail vibration damping bracket, in one installation state, the supporting surface on the upper side of the first connecting part 1 can support the second connecting plate 22 on the upper side, and in another installation state, the supporting surface on the lower side of the first connecting part 1 can support the second connecting plate 22 on the upper side, so that the first connecting part 1 can support the second connecting part 2 in both the direction of gravity and the opposite direction of gravity, thereby reducing the difficulty of installation; specifically, when the second connecting part 2 is installed with the guide rail connecting frame 100, the first connecting part 1 can be prevented from being separated from the second connecting part 2, and when the first connecting part 1 is installed with the elevator shaft wall mounting frame 200, the second connecting part 2 can be prevented from being separated from the first connecting part 1.
[0033] In another embodiment, the second connecting part 2 includes a second pressure plate 21, and a second connecting plate 22 fixedly connected to the second pressure plate 21; the second pressure plate 21 is connected to the vibration damping part 3, and the second connecting plate 22 is used to be fixedly connected to the guide rail connecting frame 100; along the direction of gravity, the second connecting plate 22 is located on the upper side of the first connecting part 1, and the supporting surface is located on the upper side of the first connecting part 1, and the supporting surface can be used to support the second connecting plate 22, thereby preventing the elevator from falling.
[0034] Further, the second connecting plate 22 includes a first plate 221 and a second plate 222; one end of the first plate 221 is fixedly connected to the second pressure plate 21, and the other end is fixedly connected to the second plate 222, and the second plate 222 is fixedly connected to the guide rail connecting frame 100 by a first bolt 5; the first plate 221 is spaced apart from the vibration damping part 3, and the second plate 222 is parallel to the second pressure plate 21, so that the direction of the force between the second connecting part 2 and the vibration damping part 3 is parallel to the central axis direction of the first bolt 5, so that the vibration during the operation of the elevator will not affect the first bolt 5, thereby ensuring the stability of the connection between the second connecting part 2 and the guide rail connecting frame 100 by the first bolt 5.
[0035] In order to ensure the overall connection strength of the second connecting part 2 without excessively increasing the counterweight of the second connecting part 2, in the present embodiment, the second pressing plate 21 and the second connecting plate 22 are integrally formed; the second pressing plate 21 and the second connecting plate 22 are configured to be plate-shaped, and the second pressing plate 21 and the second connecting plate 22 have equal thickness.
[0036] In this embodiment, the first connecting part 1 includes a first pressing plate 11, and at least two first connecting plates 12 fixedly connected to the first pressing plate 11; the first pressing plate 11 is arranged opposite to the second pressing plate 21 and connected to the vibration reduction part 3; the first connecting plate 12 is used to be fixedly connected to the elevator shaft wall mounting frame 200; the first pressing plate 11, the first connecting plate 12, the second pressing plate 21, and the second connecting plate 22 form a mounting groove for mounting the vibration reduction part 3. This arrangement can fix the relative positions of the first connecting part 1, the second connecting part 2 and the vibration reduction part 3, and the vibration reduction part 3 is stored in the mounting groove, which can reduce the aging efficiency of the vibration reduction part 3 on the one hand, and reduce the installation difficulty of the elevator guide rail vibration reduction bracket anti-separation structure and the guide rail vibration reduction bracket equipped with the anti-separation mechanism on the other hand.
[0037] Further, in this embodiment, the first pressing plate 11 is located on the side of the vibration reduction unit 3 close to the installation wall of the elevator shaft, and the second pressing plate 21 is located on the side of the vibration reduction unit 3 away from the installation wall of the elevator shaft. Specifically, the first pressing plate 11 and the vibration reduction unit 3 can be connected in an adhesive manner, and the second pressing plate 21 and the vibration reduction unit 3 can be connected in an abutting manner, which ensures the vibration reduction effect of the vibration reduction unit 3 and increases the service life of the vibration reduction unit 3.
[0038] Further, the first connecting plate 12 includes a third plate 121 and a fourth plate 122; one end of the third plate 121 is fixedly connected to the first pressure plate 11, and the other end is fixedly connected to the fourth plate 122, and the fourth plate 122 is fixedly connected to the elevator shaft wall mounting frame 200 by a second bolt 6; the third plate 121 is spaced apart from the vibration damping part 3, and the fourth plate 122 is parallel to the first pressure plate 11, so that the direction of the force between the first pressure plate 11 and the vibration damping part 3 is parallel to the central axis direction of the second bolt 6, so that the direction of the force between the first connecting part 1 and the vibration damping part 3 is parallel to the central axis direction of the second bolt 6. At this time, the vibration during the operation of the elevator will not affect the second bolt 6, thereby ensuring the stability of the connection between the second bolt 6 and the guide rail connecting frame 100.
[0039] In order to ensure the overall connection strength of the first connection part 1 without excessively increasing the weight of the first connection part 1, in this embodiment, the first pressing plate 11 and the first connecting plate 12 are integrally formed; the first pressing plate 11 and the first connecting plate 12 are equal in thickness.
[0040] See also Figures 4 to 5 The embodiment of the utility model provides an elevator guide rail vibration damping bracket, including a guide rail connecting frame 100 and an elevator shaft wall mounting frame 200, wherein the guide rail connecting frame 100 and the elevator shaft wall mounting frame 200 are connected via the above-mentioned elevator guide rail vibration damping bracket anti-separation structure.
[0041] 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.
