Description

Technical Field

[0001] The utility model belongs to the field of elevator parts and components, and in particular relates to a shock-absorbing elevator bracket. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. At the end of the 20th century, elevators used permanent magnet synchronous traction machines as their power, which greatly reduced the area occupied by the machine room. They also have the advantages of low energy consumption, energy saving and high efficiency, and high lifting speed, which greatly promoted the development of real estate towards super-high-rise buildings. The elevator bracket is a component that assists the elevator in stably moving up and down, and is an important component in the current elevator operation process.

[0003] The Chinese utility model patent is CN207192532U, which discloses a vibration-reducing and noise-reducing elevator guide rail bracket, comprising a guide rail connecting frame, an intermediate connecting frame and a hoistway connecting frame connected in sequence, wherein the intermediate connecting frame and the hoistway connecting frame are mutually embraced and a buffer pad is sandwiched between the embraced portions, and the embraced portions of the two are fixed by penetrating bolts, the intermediate connecting frame and the hoistway connecting frame are both provided with a U-shaped portion, each of the U-shaped portions has a bottom edge and two side edges, the U-shaped portions of the intermediate connecting frame and the hoistway connecting frame are mutually embraced, and the buffer pad is sandwiched between the bottom edges of the two U-shaped portions;

[0004] The above design aims to solve the problem of noise and vibration generated inside the existing elevator bracket when it is running. Buffer pads are installed between each group of connecting frames to reduce the noise generated during the operation of the elevator. Although this method is stable, there are still certain problems. Specifically, when the buffer pad is working, it basically relies on the expansion and rebound characteristics of its own material to reduce the collision between the connecting frames. Once the number of rebounds and collisions exceeds a certain limit, the shock absorbing and buffering functions of the buffer pad itself are greatly reduced, which will directly lead to the buffer pad being unable to work normally, hindering the overall operation of the equipment and affecting the working quality of the equipment itself.

[0005] In order to solve the above problems, a shock-absorbing elevator bracket is proposed in the present application. Utility Model Content

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0030] Depend on Figure 1 , Figure 2 and Figure 3As shown, a shock-absorbing elevator bracket includes a fixed slide rail 1, a movable side plate 2, a connecting block 3 and a lifting rod 4. The movable side plate 2 is fixedly installed on the side of the fixed slide rail 1, and the connecting block 3 is arranged on the side of the movable side plate 2. The connecting block 3 is symmetrically slidably installed on the lifting rod 4 inside, and a buffer mechanism 5 is symmetrically fixedly installed on the outside of the connecting block 3. The buffer mechanism 5 is installed on the top of the lifting rod 4. The buffer mechanism 5 includes a sealing cylinder 51, a matching groove 52, a pushing block 53, a conveying pipe 54 and a buffer airbag 55. The sealing cylinder 51 is symmetrically fixedly installed on the outside of the connecting block 3, and a matching groove 52 is opened inside the sealing cylinder 51. The top of the lifting rod 4 is fixedly installed with a pushing block 53, and the matching groove 52 and the pushing block 53 sliding connection, a buffer air bag 55 is fixedly installed on the inner wall of the connecting block 3, and a delivery pipe 54 is symmetrically fixedly installed on both sides of the buffer air bag 55. The delivery pipe 54 is fixedly connected to the sealing tube 51. The buffer mechanism 5 is used to utilize the thrust generated when the movable side plate 2 moves to provide a certain protection between the movable side plate 2 and the connecting block 3. The inner wall of the connecting block 3 is symmetrically fixedly installed with an extrusion mechanism 6. The extrusion mechanism 6 is used to move with the movable side plate 2 to provide power for the operation of the buffer mechanism 5. The outside of the movable side plate 2 is symmetrically fixedly installed with a limiting mechanism 7. The limiting mechanism 7 is slidably connected to the connecting block 3. The limiting mechanism 7 is used to calibrate the trajectory of the movable side plate 2 when it moves inside the connecting block 3.

[0031] In use, the fixed slide rail 1 is installed inside the elevator shaft, and then the fixed slide rail 1 is used to limit the movement of the entire elevator. When the elevator is moving, the movable side panel 2 will move into the connecting block 3 due to the collision between the elevator car and the fixed slide rail 1, and the existence of the limiting mechanism 7 can limit the movement trajectory of the movable side panel 2. When the movable side panel 2 moves, the squeezing mechanism 6 will automatically start to work, providing power for the operation of the buffer mechanism 5 and reducing a certain amount of collision force between the movable side panel 2 and the connecting block 3. Finally, the use of the buffer mechanism 5 can provide a certain amount of friction between the movable side panel 2 and the connecting block 3. A certain buffer is provided. When the lifting rod 4 moves, it drives the pushing block 53 to slide up and down stably on the inner wall of the matching groove 52, and the interior of the matching groove 52 is in a sealed state as a whole. When the pushing block 53 moves, due to the change in air pressure, a large amount of gas will enter the buffer airbag 55 through the conveying pipe 54, and collide with the volume of the buffer airbag 55. Then the buffer airbag 55 contacts the end of the movable side panel 2. The gas inside the buffer airbag 55 and the characteristics of the flexible material of the buffer airbag 55 itself are used to reduce the noise of the collision between the movable side panel 2 and the connecting block 3, reduce the force of the collision between the two, and make the elevator more stable when in use.

[0032] By the attached Figure 4As shown, in this embodiment, the pushing block 53 is interference fit with the matching groove 52, and the pushing block 53 is made of soft rubber material to ensure the sealing of the pushing block 53 when it moves inside the matching groove 52. During use, under the premise of ensuring the sealing inside the matching groove 52, every time the pushing block 53 moves a certain distance, the moving gas will be injected into the buffer airbag 55, providing power for the collision of the buffer airbag 55 and adjusting the size of the air pressure inside the matching groove 52 and the buffer airbag 55.

[0033] By the attached Figure 4 As shown, in the present embodiment, a protective layer is fixedly installed on the side of the movable side panel 2, and the protective layer is installed at a position opposite to the buffer airbag 55, so as to protect the buffer airbag 55 from being damaged due to squeezing. During use, the installation of the protective layer can ensure the overall safety of the buffer airbag 55 when the movable side panel 2 contacts the buffer airbag 55, and the outer surface of the movable side panel 2 will not cause scratches to the outer wall of the buffer airbag 55, and the protective layer itself also has a certain buffering effect.

[0034] By the attached Figure 5 As shown, in this embodiment, the extrusion mechanism 6 includes a fixed base 61, a connecting rod 62, a movable base 63, a mounting groove 64 and a spring 65. The fixed base 61 is symmetrically fixedly installed on the side of the movable side plate 2, the movable base 63 is symmetrically slidably installed on the inner wall of the connecting block 3, the connecting rod 62 is rotatably installed on the outside of the movable base 63, the connecting rod 62 is rotatably connected to the fixed base 61, the inner wall of the connecting block 3 is provided with a mounting groove 64, the spring 65 is fixedly installed inside the mounting groove 64, and the end of the spring 65 is fixedly connected to the movable base 63.

[0035] When the movable side plate 2 moves toward the connecting block 3 during use, the connecting rod 62 will automatically change and adjust the inclination angle of the connecting rod 62 itself under the premise that the distance between the movable side plate 2 and the connecting block 3 is reduced, because the overall length cannot be changed. In conjunction with the fixed base 61 and the movable base 63 installed on both sides of the connecting rod 62, the movable base 63 automatically moves along the opened sliding groove, driving the lifting rod 4 to move upward, providing power for the subsequent movement of the buffer mechanism 5. In addition, due to the presence of the spring 65, under the premise that the movable side plate 2 does not squeeze the connecting block 3, the movable base 63 will automatically return to its original position, driving the lifting rod 4 to move to the bottom, completing the rapid reset of each component.

[0036] By the attached Figure 5As shown, in this embodiment, sliding grooves are symmetrically opened inside the connecting block 3, and sliding blocks are symmetrically fixedly installed on both sides of the movable base 63. The sliding blocks are slidably connected to the sliding grooves to limit the position and trajectory of the movable base 63 when it moves on the inner wall of the connecting block 3. During use, the sliding grooves and the sliding blocks on both sides of the movable base 63 cooperate to provide a limit for the movement of the movable base 63, ensuring that the movable base 63 will only move up and down vertically when moving, and will not deviate from the originally designed track, so that the lifting and lowering of the lifting rod 4 is more stable.

[0037] By the attached Figure 6 As shown, in this embodiment, the limiting mechanism 7 includes a limiting block 71, a limiting screw 72, a limiting baffle 73 and a limiting nut 74. The limiting block 71 is symmetrically fixedly mounted on the inner wall of the movable side plate 2, and the limiting baffle 73 is symmetrically fixedly mounted on the outer surface of the connecting block 3. The limiting screw 72 is commonly threadedly mounted inside the limiting block 71 and the limiting baffle 73, and the limiting nut 74 is threadedly mounted on the end of the limiting screw 72.

[0038] During use, the limit screw 72 is rotated into the threaded groove opened inside the movable side plate 2 and the connecting block 3, and then the limit nut 74 is installed to the end of the limit screw 72 to relatively fix the position of the movable side plate 2 and the connecting block 3. The opening of the movable slide groove inside the limit baffle 73 can provide sufficient space for the limit screw 72 to move with the movable side plate 2 while ensuring that the position of the movable side plate 2 and the connecting block 3 is relatively fixed, and the movement of the movable side plate 2 itself is more stable.

[0039] By the attached Figure 6 As shown, in this embodiment, a movable slide groove is opened inside the limit baffle 73, and the movable slide groove is slidably connected to the limit nut 74. During use, while ensuring that the positions of the movable side plate 2 and the connecting block 3 are relatively fixed, sufficient space can be provided for the limit screw 72 to move along with the movable side plate 2.

[0040] By the attached Figure 1 and Figure 2 As shown, in this embodiment, the movable side panel 2 is convex in shape as a whole, and the connecting block 3 is concave in shape as a whole, so as to facilitate the splicing of the two and the sliding of the movable side panel 2 inside the connecting block 3. During use, the movable side panel 2 can better enter the connecting block 3, and the protruding part of the movable side panel 2 is used to contact the buffer mechanism 5 to achieve the purpose of shock absorption.

[0041] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
