Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to a machine room-less host arrangement structure. Background Art

[0002] Generally speaking, elevators are divided into machine-room elevators and machine-roomless elevators. Machine-roomless elevators offer a more cost-effective hoistway construction. Currently, most machine-roomless elevators have the main engine mounted on top of the auxiliary rails. This means the auxiliary rails must bear the main engine's weight and the suspension force. Therefore, the greater the elevator load, the higher the strength requirements for the auxiliary rails and their supports, which limits the available auxiliary rail specifications. Utility Model Content

[0003] Based on this, it is necessary to provide a machine room-less main engine layout structure to address the above problems, so as to reduce the load-bearing of the auxiliary rail during the use of the elevator, thereby reducing the strength requirements and cost of the auxiliary rail and expanding the range of optional specifications of the auxiliary rail and its support.

[0004] The technical solution is as follows:

[0005] This application provides a machine room-less host layout structure, including:

[0006] a first convex beam and a second convex beam, wherein the first convex beam and the second convex beam are both used to be fixed on the top of the well, and the first convex beam and the second convex beam are spaced apart in the relative direction of the front wall and the rear wall of the well;

[0007] a main beam connected between the first convex beam and the second convex beam;

[0008] A host is arranged on the host beam.

[0009] In the aforementioned machine room-less mainframe arrangement, since the first and second convex beams are both fixed to the top of the hoistway, and the mainframe beam is connected between the first and second convex beams, the first and second convex beams can reliably support the mainframe beam, so that when the mainframe is mounted on the mainframe beam, the mainframe beam can transfer its weight and hanging force to the first and second convex beams, and the first and second convex beams can transfer the load carried by the mainframe beam to the hoistway wall. Therefore, compared with the solution where the mainframe beam is mounted on the top of the auxiliary rail, this machine room-less mainframe arrangement structure can not only effectively ensure the stability of the mainframe beam, but also effectively reduce the load-bearing capacity of the auxiliary rail during use of the elevator, thereby reducing the strength requirements and cost of the auxiliary rail and expanding the range of optional specifications for the auxiliary rail and the auxiliary rail support.

[0035] See Figures 1 to 4 An embodiment of the present application provides a machine room-less host arrangement structure, comprising a host beam 2, a host 4, a first convex beam 1 and a second convex beam 5.

[0036] The first and second convex beams 1 and 5 are both fixed to the top of the hoistway 200 and are spaced apart from each other along the opposite directions of the front wall 201 and the rear wall 202 of the hoistway 200. The main frame beam 2 is connected between the first and second convex beams 1 and 5, and the main frame 4 is disposed on the main frame beam 2.

[0037] In the above-mentioned machine room-less mainframe arrangement structure, since the first convex beam 1 and the second convex beam 5 are both fixed to the top of the hoistway 200, and the mainframe beam 2 is connected between the first convex beam 1 and the second convex beam 5, the first convex beam 1 and the second convex beam 5 can reliably support the mainframe beam 2, so that when the mainframe 4 is mounted on the mainframe beam 2, the mainframe beam 2 can transfer the weight of the mainframe 4 and the hanging force it carries to the first convex beam 1 and the second convex beam 5, and the load carried by the mainframe beam 2 can be transferred to the wall of the hoistway 200 through the first convex beam 1 and the second convex beam 5. Therefore, compared with the solution in which the mainframe beam 2 is mounted on the top of the auxiliary rail 6, the machine room-less mainframe arrangement structure can not only effectively ensure the stability of the mainframe beam 2, but also effectively reduce the load-bearing capacity of the auxiliary rail 6 during the use of the elevator, thereby helping to reduce the strength requirements and cost of the auxiliary rail 6, and helping to expand the range of optional specifications of the auxiliary rail 6 and the auxiliary rail 6 support.

[0038] Combine Figures 1 to 4As shown, the main beam 2 extends in the opposite direction between the front wall 201 and the rear wall 202 of the hoistway 200. The side walls of the hoistway 200 may include the front wall 201, the rear wall 202, a first connecting wall 203 connected between the front wall 201 and the rear wall 202, and a second connecting wall 204. The first connecting wall 203 is disposed opposite the second connecting wall 204. The first connecting wall 203 is the side wall of the hoistway 200 that is closer to the main beam 2, and the rear wall 202 is the side wall of the hoistway 200 that is opposite the elevator door, that is, the elevator door is located in the front wall 201. Schematically, one end of the first convex beam 1 and one end of the second convex beam 5 can be connected to the first connecting wall 203. In this way, the first convex beam 1 and the second convex beam 5 can be set at an angle to the main beam 2. Since the main beam 2 is close to the first connecting wall 203, the first convex beam 1 and the second convex beam 5 can be set shorter to support the main beam 2; alternatively, one end of the first convex beam 1 can be connected to the first connecting wall 203, and one end of the second convex beam 5 can be connected to the rear wall 202. In this way, the first convex beam 1 is set at an angle to the main beam 2, and the fixed end of the second convex beam 5 is located at the rear end of the main beam 2. Therefore, this setting method can be used when the main beam 2 is close to the first connecting wall 203 and the rear wall 202.

[0039] In one embodiment, Figure 2 As shown, the first convex beam 1 is arranged on the side of the second convex beam 5 facing away from the rear wall 202. One end of the first convex beam 1 is connected to the first connecting wall 203 connecting the front wall 201 and the rear wall 202 of the hoistway 200, and the other end of the first convex beam 1 is connected to one end of the main beam 2. One end of the second convex beam 5 is connected to the other end of the main beam 2, and the other end of the second convex beam 5 is connected to the rear wall 202. In this way, the first convex beam 1 and the second convex beam 5 can reliably support the main beam 2, so that the load borne by the main beam 2 can be effectively transferred to the side wall of the hoistway 200, effectively ensuring the firmness and stability of the main beam 2. In principle, this arrangement can be considered when the rear end of the main beam 2 is close to the rear wall 202 and there are no other interfering devices.

[0040] Furthermore, the main beam 2 extends in the relative direction of the front wall 201 and the rear wall 202 of the hoistway 200, and the first convex beam 1 is arranged perpendicular to the main beam 2. This helps to reduce the length of the first convex beam 1, thereby saving construction costs.

[0041] Optional, such as Figure 2 As shown, the extension direction of the second convex beam 5 can be consistent with the extension direction of the main beam 2.

[0042] In another embodiment, combined Figure 1 、 Figure 3 and Figure 4As shown, the first convex beam 1 is arranged on the side of the second convex beam 5 facing away from the rear wall 202. One end of the first convex beam 1 is connected to the first connecting wall 203 connecting the front wall 201 and the rear wall 202 of the hoistway 200, and the other end of the first convex beam 1 is connected to one end of the main beam 2. The second convex beam 5 is connected to the first connecting wall 203, and the second convex beam 5 is connected to the main beam 2. In this way, the first convex beam 1 and the second convex beam 5 can reliably support the main beam 2, so that the load borne by the main beam 2 can be effectively transferred to the side wall of the hoistway 200, effectively ensuring the strength and stability of the main beam 2.

[0043] In one embodiment, combined Figures 1 to 4 As shown, the main beam 2 extends in the opposite directions of the front wall 201 and the rear wall 202 of the hoistway 200, and the first convex beam 1 is arranged perpendicular to the main beam 2. In this way, the first convex beam 1 can effectively support the main beam 2 and is conducive to reducing the length of the first convex beam 1, thereby reducing the construction cost of the elevator.

[0044] In one embodiment, combined Figure 1 、 Figure 3 and Figure 4 As shown, the main beam extends in the opposite direction of the front wall and the rear wall, and the second convex beam 5 is arranged perpendicular to the main beam 2. In this way, the second convex beam 5 can effectively support the main beam 2 and is conducive to reducing the length of the second convex beam 5, thereby reducing the construction cost of the elevator.

[0045] Furthermore, in one embodiment, in combination Figure 3 and Figure 4 As shown, the second convex beam 5 is used to connect to the rear wall 202 of the hoistway 200. Specifically, one end of the second convex beam 5 is connected to the first connecting wall 203, and the portion of the second convex beam 5 near the rear wall 202 is connected to the rear wall 202. This effectively strengthens the connection between the second convex beam 5 and the side wall of the hoistway 200, facilitating the second convex beam 5 to transfer the load of the main beam 2. This method is generally applicable when the main beam 2 is relatively close to both the first connecting wall 203 and the rear wall 202.

[0046] Further, in one embodiment, Figure 4 As shown, the other end of the second convex beam 5 is connected to the second connecting wall 204 of the well 200. In this way, it is beneficial to enhance the reliability of the connection between the second convex beam 5 and the side wall of the well 200.

[0047] Preferably, Figure 1 and Figure 3As shown, one end of the second convex beam 5 and one end of the first convex beam 1 are both connected to the first connecting wall 203, and are both arranged perpendicular to the main beam 2. In this way, the first convex beam 1 and the second convex beam 5 can jointly and reliably support the main beam 2, ensuring that the first convex beam 1 and the second convex beam 5 can reliably transfer the load borne by the main beam 2 to the wall of the hoistway 200.

[0048] Furthermore, in one embodiment, Figure 1 and Figure 2 As shown, an extension beam 2a is protruded from one end of the main beam 2 connected to the second protruding beam 5. The end of the extension beam 2a facing away from the main beam 2 is fixedly connected to the rear wall 202. This further ensures that the load borne by the main beam 2 can be effectively transferred to the wall of the hoistway 200, thereby effectively ensuring the firmness and stability of the main beam 2.

[0049] Optionally, the extension direction of the extension beam 2a is consistent with the extension direction of the main beam 2. This is conducive to ensuring the installation and construction of the main beam 2.

[0050] Indicative, such as Figure 1 and Figure 2 As shown, one end of the extension beam 2a that faces away from the main beam 2 extends into the rear wall 202 and is fixedly connected to the rear wall 202 via a filler. Optionally, the filler can be concrete.

[0051] In an optional embodiment, the machine room-less mainframe arrangement structure includes a first bolt, which is used to connect the first protruding beam 1 and the mainframe beam 2. In this way, the first bolt can firmly fix the first protruding beam 1 and the mainframe beam 2, thereby improving the connection reliability between the first protruding beam 1 and the mainframe beam 2 and ensuring the firmness and stability of the mainframe beam 2 during elevator use.

[0052] Illustratively, the first bolt may be an expansion bolt.

[0053] In an optional embodiment, the machine room-less mainframe arrangement structure includes a second bolt, which is used to connect the second protruding beam 5 and the mainframe beam 2. In this way, the second bolt can firmly fix the second protruding beam 5 and the mainframe beam 2, thereby improving the reliability of the connection between the second protruding beam 5 and the mainframe beam 2 and ensuring the firmness and stability of the mainframe beam 2 during elevator use.

[0054] Illustratively, the second bolt may be an expansion bolt.

[0055] In one embodiment, Figure 1 and Figure 2As shown, the machine room-less mainframe arrangement includes a secondary rail 6, which is disposed on the side of the mainframe beam 2 facing away from the mainframe 4 and is configured to extend along the extension direction of the hoistway 200. The secondary rail 6 is spaced apart from the mainframe beam 2. As such, the mainframe beam 2 is suspended above the secondary rail 6 and does not directly contact the secondary rail 6. This prevents the load borne by the mainframe beam 2 from being directly transferred to the top of the secondary rail 6. This effectively reduces the load-bearing capacity of the secondary rail 6 during elevator operation, lowering the strength requirements and cost of the secondary rail 6, and expanding the range of available specifications for the secondary rail 6 and its support.

[0056] Furthermore, in one embodiment, Figure 1 and Figure 2 As shown, the machine room-less mainframe arrangement includes a main rail 3 that extends along the extension direction of the hoistway 200 and is connected to the mainframe beam 2. In this way, the main rail 3 can be reliably installed in the hoistway 200 to guide the car 7 to move up and down along the main rail 3, realizing the main function of the elevator.

[0057] In an optional embodiment, the machine room-less mainframe arrangement includes a third bolt, which is used to connect the main rail 3 and the main frame beam 2. This third bolt secures the main rail 3 and the main frame beam 2 together, thereby improving the reliability of the connection between the main rail 3 and the main frame beam 2 and ensuring the firmness and stability of the main rail 3 during elevator use.

[0058] Illustratively, the third bolt may be an expansion bolt.

[0059] Furthermore, in one embodiment, in combination Figure 3 and Figure 4 As shown, the machine room-less mainframe arrangement structure includes a car 7 and a door machine 8 provided on the car 7. The car 7 is slidably connected to the main rail 3. In the extension direction of the main rail 3, the projections of the door machine 8 and the car 7 are spaced apart from the projections of the main beam 2, the first convex beam 1, and the second convex beam 5. In this way, in the extension direction of the main rail 3, there is no double image between the end of the main beam 2 near the front wall 201 and the door machine 8, and there is no double image between the car 7 and the main beam 2, the first convex beam 1, and the second convex beam 5. This ensures that when the car 7 drives the door machine 8 to move up and down along the main rail 3, there will be no interference between the main beam 2 and the door machine 8, and no interference between the car 7 and the main beam 2, the first convex beam 1, and the second convex beam 5. As a result, the car 7 can smoothly rise to the top floor, thereby ensuring the reliability and stability of the elevator operation.

[0060] Preferably, Figure 3As shown, the first convex beam 1 and the second convex beam 5 are both arranged perpendicular to the main beam 2, and the first convex beam 1 and the second convex beam 5 are both arranged on the side of the main beam 2 away from the car 7 to ensure that when the car 7 moves up and down, the first convex beam 1 and the second convex beam 5 will not interfere with the operation of the car 7.

[0061] Furthermore, in one embodiment, the machine room-less mainframe arrangement further includes a counterweight and a traction rope. The counterweight is slidably connected to the auxiliary rail 6. One end of the traction rope is connected to the car 7, and the other end is connected to the counterweight. The traction rope is drive-connected to the mainframe 4. The traction rope, driven by the mainframe 4, can cause the counterweight and car 7 to move synchronously, and the movement direction of the counterweight is opposite to that of the car 7. In this way, the car 7 can be smoothly raised and lowered along the main rail 3 under the action of the counterweight, traction rope, and mainframe 4, thereby ensuring the stability and reliability of the elevator operation.

[0062] Schematically, one end of the traction rope is connected to the top of the car 7, and the other end is connected to the end of the counterweight block close to the main beam 2.

[0063] Indicative, such as Figure 1 and Figure 2 As shown, the number of auxiliary rails 6 can be two, and the two auxiliary rails 6 are spaced apart along the extension direction of the main beam 2, and the counterweight is slidably connected between the two auxiliary rails 6. This is conducive to ensuring the stability of the counterweight during the lifting process, thereby ensuring the smooth lifting of the car 7 and improving the user experience.

[0064] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
