Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories, in particular to a shock-absorbing bracket. Background Art

[0002] With the acceleration of urbanization and the continuous emergence of high-rise buildings, elevators are an indispensable vertical transportation tool in modern urban life. Their performance and operation quality are directly related to the quality of life and safety of residents. In the elevator system, the guide rail bracket is a key component that supports the elevator guide rail and ensures its stable operation. Its design and installation process are particularly important.

[0003] The traditional fixing method of the guide rail bracket generally adopts bolt fastening or welding technology to directly connect the guide rail bracket to the building structure (such as the wall) rigidly. Although this connection method can provide sufficient support and stability to ensure the precise positioning and operation of the elevator guide rail in the vertical direction, it also has defects that cannot be ignored. During the up and down movement of the elevator car, due to the friction of mechanical parts, the imbalance of motor operation, and the influence of external factors such as wind and temperature, subtle but continuous vibrations will be generated. These vibrations are directly transmitted to the building structure through the guide rail bracket, especially the wall connected to it, which may cause resonance and aggravate the propagation and amplification of vibrations; for residents living in high-rise buildings, the noise and vibration generated by the operation of the elevator not only affects their daily life and peace, but also may have a negative impact on sleep quality, work efficiency and even physical and mental health. This problem is particularly prominent in places that are sensitive to noise or require a high-quality rest environment, such as hospital wards, libraries, and high-end residential areas. Therefore, we make improvements to this and propose a shock-absorbing bracket. Summary of the invention

[0004] The purpose of the utility model is to address the problem of rigid connection between the existing guide rail bracket and the wall, in which the slight vibration generated when the car moves up and down will be transmitted to the wall, which may cause noise intrusion to the surrounding residents.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As described in the background technology, the traditional guide rail bracket fixing method generally adopts bolt fastening or welding technology to directly rigidly connect the guide rail bracket to the building structure (such as a wall). Although this connection method can provide sufficient support and stability to ensure the precise positioning and operation of the elevator guide rail in the vertical direction, it also has defects that cannot be ignored. When the elevator car moves up and down, it will produce subtle but continuous vibrations due to the friction of mechanical parts, the imbalance of motor operation, and the influence of external factors such as wind and temperature.

[0029] In order to solve this technical problem, the utility model provides a shock-absorbing bracket, which is applied to the installation of elevator guide rails.

[0030] Specifically, please refer to Figures 1-5 , the shock-absorbing bracket specifically includes:

[0031] An outer frame 102 and a core plate 106 arranged in the outer frame 102. Front and rear shock pads 105 are arranged on both the front and rear sides of the core plate 106, and left and right shock pads 104 are arranged on both the left and right sides of the core plate 106. The left and right shock pads 104 cooperate with the front and rear shock pads 105 to achieve shock absorption between the core plate 106 and the outer frame 102.

[0032] For the shock-absorbing bracket provided by the present utility model, in this application, shock pads are arranged on all four sides of the core plate 106, realizing the all-round and multi-angle absorption and dispersion of the vibration generated during the operation of the elevator, effectively reducing the transmission of vibration energy to the wall, and significantly improving the quietness of the living environment; reducing the noise and vibration generated by the operation of the elevator, providing a quieter and more harmonious living environment for the surrounding residents, and significantly improving the living comfort and satisfaction.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0035] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0036] Example 1, please refer to Figures 1-5 , a shock-absorbing bracket, including an outer frame 102 and a core plate 106 arranged in the outer frame 102. Front and rear shock pads 105 are arranged on both the front and rear sides of the core plate 106, and left and right shock pads 104 are arranged on both the left and right sides of the core plate 106. The left and right shock pads 104 cooperate with the front and rear shock pads 105 to achieve shock absorption between the core plate 106 and the outer frame 102. In this application, shock pads are arranged on all four sides of the core plate 106, realizing the all-round and multi-angle absorption and dispersion of the vibration generated during the operation of the elevator, effectively reducing the transmission of vibration energy to the wall, and significantly improving the quietness of the living environment; reducing the noise and vibration generated by the operation of the elevator, providing a quieter and more harmonious living environment for the surrounding residents, and significantly improving the living comfort and satisfaction;

[0037] Both the front and rear shock pads 105 and the left and right shock pads 104 are made of rubber. The shock pads made of rubber have excellent elasticity and flexibility, can effectively absorb and buffer vibration energy. Their good durability makes the shock pads not easy to age and damage during long-term use, reducing the maintenance and replacement costs. The rubber material can also effectively isolate noise, further reducing the noise transmission generated during the operation of the elevator, providing a quieter living space for the residents. In addition, the wear resistance of the rubber also helps to extend the service life of the shock pads, ensuring the long-term stability of the shock absorption effect.

[0038] Further, as Figure 4 and Figure 5 shown, through holes 1051 are provided on the front and rear shock pads 105, and shock pad stop rods 301 inserted into the through holes 1051 are fixedly connected to the core plate 106. The insertion of the shock pad stop rods 301 and the through holes 1051 can limit the connection between the front and rear shock pads 105 and the core plate 106, effectively preventing the possible displacement and misalignment of the front and rear shock pads 105 during operation, ensuring that the front and rear shock pads 105 can always exert the best shock absorption effect at the predetermined position. At the same time, the stable connection also reduces the shock absorption performance fluctuations caused by the position change of the front and rear shock pads 105, making the shock absorption effect more stable and reliable.

[0039] Further, as Figures 1-5 shown, a rear cover plate 107 is provided on one side of one of the front and rear shock pads 105 away from the core plate 106, and a front end pressing plate 108 is provided between the other front and rear shock pad 105 away from the core plate 106 and the outer frame 102. The rear cover plate 107 can limit and protect the front and rear shock pads 105, and the rear cover plate 107 is also used to limit the left and right shock pads 104, reducing the reduction of shock absorption performance caused by the position deviation of the shock pads.

[0040] Further, as Figure 4 and Figure 5 shown, first pressing plates 103 are connected to both sides of the left and right shock pads 104, and the mutually remote sides of the two first pressing plates 103 are in contact with the outer frame 102 and the core plate 106 respectively. The first pressing plates 103 can prevent the direct contact between the side surfaces of the left and right shock pads 104 and the core plate 106, thereby reducing the damage to the left and right shock pads 104 caused by the side of the core plate 106.

[0041] Embodiment 2 further optimizes the shock absorption bracket provided in Embodiment 1. Specifically, a pre-compression member is provided on the outer frame 102.

[0042] Further, as Figure 3 and Figure 4As shown, the pre-tightening member includes a plurality of welding nuts 201 arranged on the outer frame 102, and the plurality of welding nuts 201 are all threadedly connected with pre-tightening bolts 202, and one end of the plurality of pre-tightening bolts 202 extends to the inner side of the outer frame 102 and contacts the first pressing plate 103 and the front pressing plate 108 respectively, and the first pressing plate 103 contacting the pre-tightening bolts 202 is the first pressing plate 103 away from the core plate 106;

[0043] The front pressure plate 108 and the first pressure plate 103 are supported by the pre-tightening bolts 202 to achieve pre-tightening of the front and rear shock-absorbing pads 105 and the left and right shock-absorbing pads 104. This design not only avoids the risk of damage to the shock-absorbing pads due to excessive deformation or stress, but also prolongs their service life and reduces the frequency of maintenance and replacement. In addition, pre-compression also eliminates the gap inside the shock-absorbing pad, making it fit more closely to the object that needs shock absorption, reducing the displacement caused by vibration or impact, thereby improving the stability of the entire system. Through pre-compression, the shock-absorbing pad can better adapt to the expected vibration or impact load. When vibration or impact occurs, the pre-compressed shock-absorbing pad can absorb and disperse energy more quickly and effectively, reducing the impact on the protected object. In addition, pre-compression also enhances the vibration and noise reduction effect of the shock-absorbing pad, reducing the noise level when the system is working.

[0044] Further, such as Figure 1 As shown, the outer frame 102 is provided with expansion bolts 401 , and the expansion bolts 401 are used for installing the outer frame 102 , that is, the outer frame 102 can be fixed to the wall through the expansion bolts 401 .

[0045] Further, such as Figure 1 and Figure 5 As shown, two sealing plates 101 are arranged between the rear cover plate 107 and the outer frame 102, the sealing plates 101 and the outer frame 102 are welded together, and shock-absorbing bracket openings 1011 are opened between the sealing plates 101 and the rear cover plate 107. The setting of the shock-absorbing bracket openings 1011 can avoid the collision between the core plate 106 and the rear cover plate 107 and the sealing plate 101 due to the deformation of the shock-absorbing rubber when vibration occurs, thereby further enhancing the stability and reliability of the system.

[0046] Embodiment 3 further optimizes the shock-absorbing bracket provided in Embodiment 1 or 2. Specifically, Figures 1-2 As shown, both ends of the core plate 106 extend out of the outer frame 102 and are bent, a support frame 2 is connected between the two core plates 106, and the support frame 2 and the core plate 106 are connected by bolts.

[0047] Further, such as Figure 1 As shown, two elongated holes 502 are provided on the support frame 2, and the two elongated holes 502 are both connected with a guide rail pressing plate 501 through bolts, and the guide rail pressing plate 501 is used to achieve the tightening of the guide rail.

[0048] The usage process of the shock-absorbing bracket provided by the present utility model is as follows:

[0049] The outer frame 102 is fixed on the wall through the expansion bolt 401, and then the guide rail can be pressed on the support frame 2 through bolts and the guide rail pressing plate 501 to complete the installation. During the usage process, the front and rear shock pads 105 and the core plate 106 can shock-absorb the four sides of the core plate 106, achieving the all-round and multi-angle absorption and dispersion of the vibration generated during the elevator operation, effectively reducing the transmission of vibration energy to the wall, and significantly improving the quietness of the living environment.
