Description

Technical Field

[0001] The invention relates to the field of elevator engineering production, in particular to a guide rail bracket for an elevator. Background Art

[0002] In the elevator system, the guide rail bracket is a key component for supporting and fixing the guide rail. Its performance is directly related to the safety and stability of the elevator operation. When the elevator car or counterweight moves up and down in the hoistway, various factors such as the friction between the guide shoe and the guide rail, the shaking of the car, and the vibration of the drive main unit will cause the vibration of the guide rail. These vibrations are transmitted to the hoistway wall through the guide rail bracket. The long-term accumulated vibration impact will not only have an adverse effect on the structural life of the building wall, but also may cause low-frequency noise pollution, seriously affecting the acoustic environment in the building.

[0003] Expansion bolts are generally used to anchor the guide rail bracket to the hoistway wall to ensure the stability of the bracket. During the normal operation of the elevator, especially in conditions such as the passage of the car or counterweight and emergency braking, the guide rail bracket plays a vital restraining role. To ensure the safety of the elevator under extreme working conditions, the guide rail bracket is designed to have high strength and high rigidity to effectively limit the displacement and deformation of the guide rail and ensure that it is within a safe and reasonable range.

[0004] However, in the pursuit of elevator running smoothness and reducing vibration transmission, the design of the guide rail bracket faces a critical trade-off. In order to reduce the vibration transmitted from the guide rail to the shaft wall, a common practice is to design the guide rail bracket to have a certain degree of elasticity. This elastic design can significantly improve the vibration isolation effect of the bracket and effectively reduce the impact of vibration on the shaft wall and indoor sound environment, but at the same time, the elastic design of the bracket inevitably reduces its restraint ability on the guide rail. In extreme cases such as the passage of the car or counterweight, emergency stop of the elevator, and earthquakes, the guide rail is more likely to deform and shift. This potential guide rail instability phenomenon may pose a serious threat to the normal operation of the elevator equipment and the safety of passengers. Summary of the invention

[0005] In order to overcome some of the problems mentioned in the above background, the present invention provides a guide rail bracket for an elevator.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0019] Elevator guide rails are key components to ensure the smooth operation of elevators, so they must be installed on both sides of the elevator's running path. In order to facilitate production, transportation and installation, guide rails are usually processed into a standard length of 2.5 meters, and these segmented guide rails are spliced ​​into a complete guide rail system. As the key structure connecting the guide rails to the hoistway wall, the guide rail bracket plays a vital role in supporting and fixing the guide rails.

[0020] like Figure 1-Figure 6 As shown, in some embodiments, a guide rail bracket for an elevator includes a connection module and a shock absorbing module. Through the cooperation between the two modules, the normal operation of the elevator guide rail can be ensured while reducing the impact of vibration on the wall during the operation of the elevator.

[0021] In particular, the damping module is installed in the connection module, and the vibration during the operation of the elevator is effectively absorbed by the damping module, and the noise of the elevator operation is reduced. The main responsibility of the connection module is to ensure that the guide rail 5 and the elevator shaft side wall 1 can be firmly and effectively connected.

[0022] First, the connecting wall plate 2, the supporting mechanism 3 and the upper connecting plate 4 are specially designed in the connecting module. Specifically, the supporting mechanism 3 is installed between the connecting wall plate 2 and the upper connecting plate 4. Through such a layout, the stability of the entire structure is ensured. In particular, a shock absorbing chamber is designed between the supporting mechanism 3 and the upper connecting plate 4, and the shock absorbing module is installed in the shock absorbing chamber to protect the shock absorbing module.

[0023] Secondly, the shock absorbing module includes a shock absorbing member 8, which is precisely installed in the shock absorbing chamber. The main function of the shock absorbing member 8 is to reduce the direct rigid contact between the upper connecting plate 4 and the supporting mechanism 3, which can effectively reduce the vibration and noise that may be generated during the operation of the elevator, thereby reducing the impact of the vibration during the operation of the elevator on the side wall of the elevator shaft, thereby improving the safety of the elevator operation.

[0024] Furthermore, in some embodiments, the connecting wall panels 2 include two types: a single connecting wall panel 22 and a double connecting wall panel 21. The single connecting wall panel 2 is specially designed to be installed at the upper and lower ends of the elevator shaft side wall 1, fixing the upper and lower ends of the guide rail 5, and providing necessary support and fixing for the guide rail 5. The design of the single connecting wall panel 2 can ensure the stability and reliability of the elevator guide rail bracket during installation.

[0025] The double-jointed wall plate 2 is designed to be installed between two sections of upper and lower assembled guide rails 5 to ensure the stability of the connection between the guide rails 5 and the smooth transition of the overall structure. The design of the double-jointed wall plate 2 can not only improve the stability and firmness of the elevator guide rail bracket, but also ensure the safety and reliability of the elevator guide rail bracket during use.

[0026] Since the flatness of the elevator shaft wall 1 may vary to a certain extent, if the guide rail 5 is directly installed, it may cause deviation of the guide rail 5 during the installation process, affecting the normal operation of the elevator. The design of the connecting wall plate 2 and the supporting mechanism 3 can effectively compensate for this flatness difference, so that the guide rail 5 can remain horizontal during installation, ensuring the stability and safety of the elevator operation. In addition, the double connecting wall plate 21 can also play a role in strengthening the overall structure of the elevator guide rail bracket, improving the load-bearing capacity and seismic performance of the elevator guide rail bracket.

[0027] Furthermore, in some embodiments, the support mechanism 3 and the upper connecting plate 4 are connected and fixed by multiple first connecting bolts 7. These first connecting bolts 7 are carefully arranged at the four corners of the support mechanism 3 to ensure the stability and bearing capacity of the entire structure of the support mechanism 3 and the upper connecting plate 4.

[0028] Specifically, the support mechanism 3 includes a support frame 31, a bottom plate 32 and a connection ear 33. The support frame 31 is designed to be installed on the outside of the shock-absorbing chamber, and such a design can effectively protect the shock-absorbing chamber and prevent larger foreign objects from entering the shock-absorbing chamber and affecting the shock-absorbing module in the shock-absorbing chamber. The support frame 31 and the bottom plate 32 are tightly combined together by a firm connection method, and such a firm connection method ensures the integrity and durability of the support mechanism 3.

[0029] Connecting ears 33 are respectively provided on two opposite sides of the base plate 32, and these connecting ears 33 are connected and fixed to the wall plate 2 by expansion fixing bolts 6. In particular, the connecting holes on the connecting ears 33 are arranged as elongated holes. The purpose of such arrangement is to fine-tune the position of the supporting mechanism 3 so that the installation position of the guide rail 5 meets the installation specifications.

[0030] In addition, a first through hole 34 is designed in the central area of ​​the bottom plate 32, through which the shock absorbing member 8 can pass through and extend to one side of the upper connecting plate 4, thereby forming an elastic support between the two. This elastic support design can effectively absorb the impact force generated when the elevator is running, protect the elevator guide rail 5 and the supporting mechanism 3 from damage, and also improve the stability and comfort of the elevator operation.

[0031] Furthermore, in some embodiments, a plurality of second through holes are configured on the upper connecting plate 4. These second through holes are carefully designed in the outer area of ​​the shock absorber 8 to play a role of avoidance. Through these second through holes, the guide rail 5 and the upper connecting plate 4 are firmly connected by the second connecting bolts 9, so that a stable whole is formed between the upper connecting plate 4 and the guide rail 5, and the force bearing area of ​​the fixing part of the guide rail 5 is increased. This design ensures a stable connection between the guide rail 5 and the bracket, and improves the reliability and safety of the entire guide rail system.

[0032] The shock absorbing module further includes a plurality of compression springs 71 . The compression springs 71 are arranged on the outside of the first connecting bolt 7 and in the shock absorbing chamber. The compression springs 71 are used to assist the shock absorbing member 8 in working.

[0033] like Figure 5 As shown, in some embodiments, the shock absorbing module also includes a plurality of compression springs 71, which are installed on the outside of the first connecting bolt 7 and are arranged in the shock absorbing chamber. Their function is to assist the shock absorbing member 8 in working, thereby ensuring that the elevator can be more stable and safe during operation.

[0034] Specifically, these compression springs 71 are in a compressed state during installation, so that a certain distance is left between the side of the upper connecting plate 4 and the supporting mechanism 4. This distance must be smaller than the length of the elevator guide rail 5 inserted into the guide shoe. This allows the guide rail 5 to produce slight shaking during the operation of the elevator, which can be absorbed by the compression spring 71, reducing the vibration and impact force generated during the operation of the elevator, reducing the noise during the operation of the elevator, and improving the riding comfort.

[0035] like Figure 1 - Figure 3 As shown, in some embodiments, a plurality of sleeves 51 and a plurality of connection holes are respectively provided at both ends of the guide rail 5. These connection holes penetrate the guide rail 5 and the sleeve 51, and are provided one-to-one with the plurality of second through holes. These connection holes and the second through holes can be tightly connected by the second connection bolts 9. This design makes the connection between the guide rail 5 and the upper connection plate 4 more stable, and improves the safety and reliability of the elevator operation.

[0036] At the same time, the sleeve 51 is arranged between the guide rail 5 and the upper connecting plate 4. When the upper connecting plate 4 or the guide rail 5 is deformed when the elevator is running under extreme conditions, the connection between the two is less affected by the deformation under the action of the sleeve 51, so that the two are always in a connected state, thereby ensuring that the connection between the two is more stable and effectively ensuring the safe operation of the elevator.

[0037] Furthermore, in some embodiments, the shock absorber 8 is made of a soft and elastic material, and the selection of such material ensures that the shock absorber can produce corresponding deformation and return to its original state when subjected to external force. In particular, the upper end portion of the shock absorber 8 is carefully designed into an arc structure, and such a design enables the top of the arc to be firmly against one side of the upper connecting plate 4. This contact mode enables the shock absorber 8 to prevent the upper connecting plate 4 from moving further when it moves toward the side wall 1 of the elevator shaft, thereby avoiding direct rigid contact between the upper connecting plate 4 and the supporting mechanism 3, and ensuring a stable connection between the shock absorber 8 and the upper connecting plate 4.

[0038] In addition, the lower end of the shock absorber 8 is designed to be cylindrical, which facilitates its passing through the first through hole 34 on the bottom plate 32, so that its bottom passes through the shock absorber bin and contacts the wall connecting plate 2. Through this design, the shock absorber 8 can effectively transmit and buffer the force between the upper connecting plate 4 and the wall connecting plate 2, thereby achieving a shock absorbing effect.

[0039] The typical working process of the above embodiment is as follows: First, according to the specific construction plan, the installation position of the guide rail 5 is determined, and the installation positions of the upper and lower single-joined wall panels 22 and the position of the double-joined wall panel 21 in the middle are determined, and then the single-joined wall panels 22 and the double-joined wall panels 21 are respectively fixed to the elevator shaft side wall 1 using expansion fixing bolts 6. The support mechanism 3 is connected to the expansion fixing bolts 6 through the connecting ears 33, so that the three of the wall panel 2, the support mechanism 3 and the expansion fixing bolts 6 are fixed into an integral structure.

[0040] Before fixing the supporting mechanism 3, the screw rod portion of the first connecting bolt 7 is passed through the bottom plate 32, and the cylindrical end of the shock absorbing member 8 is inserted into the first through hole 34 so that the arc surface thereof is located in the shock absorbing chamber.

[0041] Secondly, after the supporting mechanism 3 is fixed, the compression spring 71 is sleeved onto the outside of the screw rod of the first connecting bolt 7 .

[0042] The upper connecting plate 4 and the end of the guide rail 5 are fixedly connected by a second connecting bolt 9. After connection, the two are connected to form an integral structure 2, and the integral structure 1 and the integral structure 2 are connected to leave a specified gap between the upper connecting plate 4 and the upper surface of the support frame 31.

[0043] Finally, according to the specific situation of the guide rail 5 after connection, the position of the support mechanism 3 is fine-tuned to make the guide rail 5 meet the installation specifications.

[0044] The above is the whole process of installing the guide rail 5 and the guide rail bracket. Repeating this process can complete the overall installation of the guide rail.
