Description

Technical Field

[0001] The invention relates to the field of elevators, and in particular to an elevator buffer base. Background Art

[0002] An elevator is a lifting device that serves between floors of a high-rise building. During the operation of an elevator, if the elevator system fails, the elevator may stop running at the least, or the elevator car may fall, threatening the lives of passengers. Therefore, people usually install buffers in the elevator pit to cushion the elevator car when it falls, thereby reducing the impact force on the passengers in the elevator car caused by the elevator falling, thereby reducing the degree of injury to the passengers.

[0003] At present, the buffer is usually installed within the vertical projection range of the elevator car by means of an elevator buffer base arranged at the bottom of the elevator shaft pit. However, this arrangement has high requirements for the pit depth design and the layout of the elevator components in the pit. On the one hand, in the deeper pit design, the height of the buffer base is required to be increased, resulting in increased weight and inconvenience in installation and adjustment, thereby increasing the cost. In addition, since the connection between the buffer base and the ground usually adopts low-strength expansion bolts, the buffer base is easily deformed and separated from the ground when the elevator car hits the buffer, resulting in poor buffering effect of the buffer. On the other hand, in the shallower pit design, the buffer base and the buffer occupy too much pit space, making it difficult to layout the components of the elevator pit.

The specific design features disclosed in the present invention (including, for example, specific dimensions, directions, locations, and shapes) will be determined in part by the specific intended application and use environment.

[0047] The following will be referred to in detail various embodiments of the present invention, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modifications, equivalent forms and other embodiments that can be included in the spirit of the present invention and within the scope defined by the appended claims.

[0048] Combine the following Figures 1 to 5 The structure of the elevator buffer base according to the embodiment of the present invention will be described.

[0049] Figure 1 A schematic diagram of an elevator buffer base being installed to an elevator according to an exemplary embodiment of the present invention; Figure 2 A schematic structural diagram of a buffer mounting bracket according to an exemplary embodiment of the present invention; Figure 3 is another structural schematic diagram of a buffer mounting bracket according to an exemplary embodiment of the present invention; Figure 4 A schematic diagram of a first buffer mounting bracket being mounted to a first guide rail according to an exemplary embodiment of the present invention; Figure 5 It is a partially exploded schematic diagram of a first buffer mounting bracket being mounted to a first guide rail according to an exemplary embodiment of the present invention.

[0050] First, it should be noted that the elevator of the present invention includes guide rails 200 arranged on both sides of the elevator shaft and an elevator car 100 (such as Figure 1 Meanwhile, for the convenience of description, the position between the guide rails 200 on both sides of the elevator shaft is defined as the inner side of the guide rails 200 , and the position outside the guide rails 200 on both sides of the elevator shaft is defined as the outer side of the guide rails 200 .

[0051] According to an exemplary embodiment of the present invention, Figure 1 As shown, the elevator buffer base of the embodiment of the present invention includes at least one buffer mounting frame 300. The buffer mounting frame 300 is mounted to the guide rails 200 on both sides of the elevator hoistway and / or the pit walls on both sides of the elevator hoistway, and the buffer mounting frame 300 is located outside the range of the projection of the elevator car 100 in the vertical direction.

[0052] The buffer mounting frame 300 is used to mount the buffer 400, and the buffer 400 is used to buffer the fall of the elevator car 100. The buffer mounting frame 300 can be mounted to the guide rails 200 on both sides of the elevator shaft, and can also be mounted to the bottom pit walls on both sides of the elevator shaft. Preferably, the buffer mounting frame 300 can be mounted to the guide rails 200 on both sides of the elevator shaft and the bottom pit walls on both sides of the elevator shaft at the same time.

[0053] Furthermore, if Figure 1 As shown, the guide rail 200 includes a first guide rail 201 located on the left side of the elevator shaft and a second guide rail 202 located on the right side of the elevator shaft. The buffer mounting frame may include a first buffer mounting frame 301 and a second buffer mounting frame 302. The first buffer mounting frame 301 can be simultaneously mounted to the first guide rail 201 and the bottom pit wall on the same side as the first guide rail 201. The second buffer mounting frame 302 is symmetrically mounted to the second guide rail 202 and the bottom pit wall on the same side as the second guide rail 202 with the center of the connecting line of the first guide rail 201 and the second guide rail 202 as the axis of symmetry with the center of the first buffer mounting frame 301. In this way, the buffer mounting frame 300 can be made more stable, so that when the elevator car 100 hits the buffer 400, the buffer mounting frame 300 is not easily deformed and is not easily separated from the guide rail 200 and the bottom pit wall, so that the buffer 400 has a better buffering effect. At the same time, the first buffer mounting frame 301 and the second buffer mounting frame 302 are arranged symmetrically on both sides of the elevator car 100, so that the elevator car 100 can be subjected to force more evenly, thereby obtaining better buffering.

[0054] In addition, the buffer mounting bracket 300 may be disposed outside the projection range of the elevator car 100 in the vertical direction and at a first predetermined height from the pit floor, so as to mount the buffer outside the projection range of the elevator car 100 in the vertical direction and at a second predetermined height from the pit floor. Specifically, in an exemplary embodiment of the present invention, as Figure 1 As shown, the first buffer mounting frame 301 is located on the outside of the first guide rail 201, and the second buffer mounting frame 302 is located on the outside of the second guide rail 202. Accordingly, a buffer portion 110 corresponding to the buffer 400 may be provided on the side of the bottom of the elevator car 100. When the elevator car 100 falls accidentally, the buffer 400 may contact the buffer portion 110 before the elevator car 100 hits the pit floor to buffer the elevator car 100. In this way, for different pit depth designs, the first predetermined height and the second predetermined height may be adjusted so that the buffer 400 can achieve a predetermined buffering effect, thereby making the buffer mounting frame 300 of the present invention more cost-effective, easy to install and adjust, and more adaptable in different pit depth designs. At the same time, the buffer mounting frame of the present invention can save pit space, which is beneficial to the layout of the components of the elevator pit.

[0055] According to an exemplary embodiment of the present invention, Figures 1 to 3 As shown, the buffer mounting frame 300 includes a buffer supporting component 310 and a pit wall fixing plate 320 .

[0056] A buffer 400 for buffering the fall of the elevator car 100 is disposed on the upper side of the buffer support member 310. One side of the pit wall fixing plate 320 is connected to the buffer support member 310, and the other side of the pit wall fixing plate 320 extends in a first direction and is bent when extending to a predetermined length to form a first joint surface 321 connected to the pit wall.

[0057] Specifically, in the exemplary embodiment of the present invention, the pit wall fixing plate 320 of the first buffer mounting frame 301 extends toward the outside of the first guide rail 201 and bends when extending to a predetermined length, and the pit wall fixing plate 320 of the second buffer mounting frame 302 extends toward the outside of the second guide rail 202 and bends when extending to a predetermined length, so as to form first joint surfaces 321 connected to the pit walls on both sides of the elevator shaft, respectively.

[0058] According to an exemplary embodiment of the present invention, Figure 3 As shown, the other side of the bend of the pit wall fixing plate 320 is provided with a plurality of mounting grooves 322 extending in the horizontal direction. Among them, at least one bolt 323 can pass through the mounting groove 322 in a repositionable manner to connect the pit wall fixing plate 320 to the pit wall of the elevator shaft. Specifically, in an exemplary embodiment of the present invention, four mounting grooves 322 are provided on each buffer mounting frame. That is to say, the pit wall fixing plate 320 of the first buffer mounting frame 301 is provided with four mounting grooves 322, and the pit wall fixing plate 320 of the second buffer mounting frame 302 is provided with four mounting grooves 322. Four bolts 323 are provided on each buffer mounting frame, and they pass through the corresponding four mounting grooves 322 respectively, so as to connect the pit wall fixing plate 320 of the first buffer mounting frame 301 and the pit wall fixing plate 320 of the second buffer mounting frame 302 to the pit walls on both sides of the elevator shaft (matching Figure 1 The bolt 323 may be an expansion bolt, and the position of the bolt 323 in the mounting groove 322 may be adjusted to facilitate adjusting the position where the bolt 323 is connected to the bottom pit wall.

[0059] In addition, as an option, the pit wall fixing plate 320 can also be connected to the pit wall through a pre-buried groove in the pit wall and a connecting bolt corresponding to the pre-buried groove, or can be connected to the pit wall by welding to the pre-buried steel plate in the pit wall. However, it should be clear that the connection method in the present invention is not limited to this, and it can be any form in the prior art as long as it can achieve the above functions.

[0060] According to an exemplary embodiment of the present invention, Figures 1 to 3 As shown, the buffer mounting frame 300 further includes a guide rail fixing plate 330. One side of the guide rail fixing plate 330 is connected to the buffer supporting component 310, and the other side of the guide rail fixing plate 330 extends in the second direction to form a second coupling surface 331 connected to the outer side surface of the guide rail 200. The first direction and the second direction are two different directions.

[0061] Specifically, in the exemplary embodiment of the present invention, the second direction is a direction perpendicular to the first direction. Further, in the exemplary embodiment of the present invention, the other side of the guide rail fixing plate 330 of the first buffer mounting frame 301 extends toward the first guide rail 201 to form a second coupling surface 331 connected to the outer side surface of the first guide rail 201. The other side of the guide rail fixing plate 330 of the second buffer mounting frame 302 extends toward the second guide rail 202 to form a second coupling surface 331 connected to the outer side surface of the second guide rail 202.

[0062] According to an exemplary embodiment of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the guide rail 200 includes an upper guide rail 210, a lower guide rail 220, a guide rail connecting plate 230 and a connector 240. The end surface of the upper guide rail 210 and the end surface of the lower guide rail 220 can be joined by the guide rail connecting plate 230 and the connector 240, so that the guide rail 200 is easy to transport and install while ensuring a predetermined length.

[0063] The upper guide rail 210 and the lower guide rail 220 are respectively provided with a plurality of first connection holes 211, and the guide rail connecting plate 230 is provided with second connection holes 231 corresponding to the first connection holes 211. The guide rail fixing plate 330 can be provided between the guide rail connecting plate 230 and the guide rail 200, and is provided with a plurality of through holes 332 corresponding to the plurality of second connection holes 231. The connecting member 240 is sequentially inserted into the first connection hole 211, the through hole 332 and the second connection hole 231 to join the upper guide rail 210 and the lower guide rail 220, and the guide rail fixing plate 330 is pressed against the outer side surface of the upper guide rail 210 and the lower guide rail 220. In this way, the upper guide rail 210 and the lower guide rail 220 are joined by the guide rail connecting plate 230, and the guide rail fixing plate 330 is connected to the guide rail 200, which ensures the tightness of the connection, saves materials and reduces costs.

[0064] Specifically, Figure 1 and Figure 4 As shown, the upper guide rail 210 and the lower guide rail 220 of the first guide rail 201 are respectively provided with four first connection holes 211. The guide rail connecting plate 230 of the first guide rail 201 is provided with eight second connection holes 231, which correspond to the four first connection holes 211 of the upper guide rail 210 and the four first connection holes 211 of the lower guide rail 220 respectively. The guide rail fixing plate 330 of the first buffer mounting frame 301 is provided between the guide rail connecting plate 230 of the first guide rail 201 and the first guide rail 201, and is provided with eight through holes 332 corresponding to the eight second connection holes 231. The eight connecting members 240 are sequentially inserted into the second connection holes 231, the through holes 332 and the first connection holes 211 to engage the upper guide rail 210 and the lower guide rail 220 of the first guide rail 201, and the guide rail fixing plate 330 of the first guide rail 201 is pressed against the outer side surfaces of the upper guide rail 210 and the lower guide rail 220. In an exemplary embodiment of the present invention, the second guide rail 202 is centrally symmetrical with the first guide rail 201 and the second buffer mounting bracket 302 is centrally symmetrical with the first buffer mounting bracket 301. Therefore, the structure and connection method of the second guide rail 202 and the second buffer mounting bracket 302 are basically the same as the above-mentioned structure and connection method, and will not be elaborated here.

[0065] According to an exemplary embodiment of the present invention, Figure 2 and Figure 5 As shown, the guide rail fixing plate 330 further includes a gasket 334. The gasket 334 is arranged between the guide rail fixing plate 330 and the guide rail 200 corresponding to the guide rail connecting plate 230. The material of the gasket 334 can be metal, preferably steel. By adjusting the number of gaskets 334, the tightness between the guide rail connecting plate 230, the guide rail fixing plate 330 and the guide rail 200 can be adjusted, and the connecting member 240 is not easy to fall off from the guide rail connecting plate 230, the guide rail fixing plate 330 and the guide rail 200, thereby improving the stability of the buffer mounting frame 300. At the same time, by adjusting the position and number of gaskets 334, the side of the upper guide rail 210 and the side of the lower guide rail 220 can also be made smoother, thereby ensuring the verticality requirement of the elevator guide rail.

[0066] According to an exemplary embodiment of the present invention, Figures 1 to 4 As shown, the guide rail fixing plate 330 further includes two rows of guide rail pressing plates 333. The two rows of guide rail pressing plates 333 are evenly arranged on the guide rail fixing plate 330 and are respectively located above and below the guide rail connecting plate 230. Here, evenly arranged means that the number is equal and the positions are arranged correspondingly. The two rows of guide rail pressing plates 333 are respectively pressed against the inner side of the edge of the guide rail 200 to press the guide rail fixing plate 330 to the outer side of the guide rail 200 (such as Figure 4Specifically, the number of guide rail pressing plates 333 in each column is 4, and two of them are located above the guide rail connecting plate 230, and the other two are located below the guide rail connecting plate 230.

[0067] According to an exemplary embodiment of the present invention, Figures 1 to 4 As shown, the buffer mounting frame 300 further includes a transition portion 340. The transition portion 340 is disposed between the buffer support component 310 and the guide rail fixing plate 330, so that the guide rail fixing plate 330 is connected to the buffer support component 310 through the transition portion 340. The transition portion 340 is used to adjust the extension direction of the guide rail fixing plate 330, so that the second bonding surface 331 formed by the guide rail fixing plate 330 can be better fitted to the outer side surface of the guide rail 200, thereby ensuring the tightness of the second bonding surface 331 connected to the outer side surface of the guide rail 200. The transition portion 340 can be connected to the guide rail fixing plate 330 and the buffer support component 310 in an integral manner, and can also be connected to the guide rail fixing plate 330 and the buffer support component 310 by welding.

[0068] According to an exemplary embodiment of the present invention, Figure 2 and Figure 3 As shown, the buffer support component 310 includes a vertical support plate 311, a buffer connection plate 312 and at least one reinforcement plate 313. One side of the vertical support plate 311 is connected to the bottom pit wall fixing plate 320, and the other side of the vertical support plate 311 is connected to the guide rail fixing plate 330. The vertical support plate 311 is mainly used to support the buffer 400.

[0069] The buffer connecting plate 312 is arranged on the upper side of the vertical support plate 311, and the buffer connecting plate 312 is used to connect the buffer 400. Specifically, in an exemplary embodiment of the present invention, one side of the vertical support plate 311 can be connected to the pit wall fixing plate 320 by welding, and the other side of the vertical support plate 311 can be connected to the guide rail fixing plate 330 by welding. The bottom of the buffer 400 is set to a disc shape, and accordingly, the buffer connecting plate 312 is also set to a disc shape. Alternatively, the shape of the buffer connecting plate 312 can also be set to other shapes as long as it corresponds to the shape of the bottom of the buffer 400. By passing a set of bolts through the buffer connecting plate 312 and the bottom of the buffer 400, the buffer 400 can be fastened to the center position of the upper side of the buffer connecting plate 312.

[0070] At least one reinforcing plate 313 is disposed between the vertical support plate 311 and the buffer connecting plate 312, and extends along the length direction of the vertical support plate 311 to strengthen the supporting strength of the vertical support plate 311. Specifically, in the exemplary embodiment of the present invention, two reinforcing plates 313 are disposed on each buffer mounting frame and are respectively located at the center positions on both sides of the vertical support plate 311. That is, the vertical support plate 311 of the first buffer mounting frame 301 is provided with two reinforcing plates 313 and are respectively located at the center positions on both sides of the vertical support plate 311, and the vertical support plate 311 of the second buffer mounting frame 302 is provided with two reinforcing plates 313 and are respectively located at the center positions on both sides of the vertical support plate 311. One end of the reinforcing plate 313 is connected to the lower side of the buffer connecting plate 312, and the other end of the reinforcing plate 313 extends to the middle of the vertical support plate 311. It should be clear that the position where the reinforcing plate 313 is disposed can be adjusted according to actual needs, for example, it can be disposed on the adapter 340 to strengthen the strength of the adapter 340. The number of reinforcing plates 313 can also be adjusted according to actual needs.

[0071] The installation process of the elevator buffer base according to the implementation scheme of the present invention will be described below with reference to the accompanying drawings.

[0072] The guide rail fixing plate 330 of the first buffer mounting frame 301 is connected to a position between the upper guide rail 210 and the lower guide rail 220 of the first guide rail 201 on the left side of the elevator shaft through the guide rail connecting plate 230, and the guide rail fixing plate 330 of the second buffer mounting frame 302 is connected to a position between the upper guide rail 210 and the lower guide rail 220 of the second guide rail 202 on the right side of the elevator shaft through the guide rail connecting plate 230.

[0073] The two rows of guide rail pressing plates 333 of the first buffer mounting frame 301 are respectively pressed against the inner side of the edge of the first guide rail 201 on the left side of the elevator shaft, so that the guide rail fixing plate 330 of the first buffer mounting frame 301 is pressed against the outer side of the first guide rail 201. The two rows of guide rail pressing plates 333 of the second buffer mounting frame 302 are respectively pressed against the inner side of the edge of the second guide rail 202 on the right side of the elevator shaft, so that the guide rail fixing plate 330 of the second buffer mounting frame 302 is pressed against the outer side of the second guide rail 202.

[0075] The buffer 400 is connected to the upper side of the buffer supporting member 310 through the buffer connecting plate 312 .

[0076] The elevator buffer base of the present invention can stably support the buffer arranged thereon when the elevator car falls, so as to buffer the elevator car, thereby reducing the impact force on the passengers in the elevator car caused by the elevator falling, thereby reducing the degree of injury to the passengers. At the same time, the elevator buffer base of the present invention is arranged on the walls and guide rails on both sides of the elevator shaft, and can adjust its position on the walls and guide rails on both sides of the elevator shaft according to different pit depths, thereby saving costs, facilitating installation and adjustment, and being more adaptable in different pit depth designs. In addition, the elevator buffer base of the present invention can save pit space, which is more conducive to the layout of the components of the elevator pit.
