[0031] The following is the specific embodiment of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configuration and assembly are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.
[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.
[0033] Self-propelled rail elevators use driving wheels to drive the car frame to move up and down on the guide rails. They can be used in buildings such as villas. Their application scenarios are often very limited in space. Therefore, it is necessary to consider reducing the hoistway space occupied by the elevator during design. This application optimizes the structure of the self-propelled rail elevator in order to reduce the hoistway space occupied.
[0034] The self-propelled rail elevator provided in the present application includes a plurality of first guide rails, a car frame, and a driving device. The car frame is provided with a car space for accommodating people or objects. The driving device is used to drive the car frame to rise and fall along the first guide rails to realize vertical transportation of people or objects.
[0035] refer to Figure 1 The self-driven rail elevator comprises a first guide rail 10, a car frame 20, and a driving device 30. The driving device 30 is used to drive the car frame 20 to move along the first guide rail 10. The driving device 30 comprises a driving wheel 31 and a driving source. The driving source is used to drive the driving wheel 31 to rotate to achieve movement. Moreover, under the drive of the driving source, the driving wheel 31 can move on the first guide rail 10 or other guide rails. The driving device 30 is connected to the car frame 20, and the driving device 30 can drive the car frame 20 to move up and down together.
[0036] Continue to refer Figure 2 and Figure 3 The first guide rail 10 has a guide rail groove 11 with one side open, and the guide rail groove 11 is surrounded by a plurality of guide rail walls 12. A guide limit device 40 is provided on the car frame 20, and at the same time, Figure 5 The guide limiting device 40 includes a support 41 and a plurality of limiting rollers 42, the plurality of limiting rollers 42 are arranged on the support 41, and the limiting rollers 42 are at least partially accommodated in the guide rail groove 11. The plurality of limiting rollers 42 are arranged in a plurality of directions, and the limiting rollers 42 in different directions respectively press the guide rail wall 12 in the corresponding direction to limit the car frame 20 on the first guide rail 10.
[0037] The plurality of limiting rollers 42 include limiting rollers 42 in multiple directions to achieve limiting in various directions. For any limiting roller 42, part or all of it is accommodated in the guide rail groove 11, thereby making full use of the internal space of the guide rail, thereby reducing the space occupied by the elevator equipment around the car frame.
[0038] It should be understood that the guide limit device includes a support and a plurality of limit rollers, and the plurality of limit rollers press the first guide rail from multiple directions to jointly limit the car frame on the first guide rail. The guide limit device is arranged around the car frame, and the inner groove of the first guide rail is used to accommodate the guide limit device, thereby obtaining a more compact structure. Figure 2 and Figure 3In the figure, the inner space of the guide rail groove 11 is shown by a dotted line frame.
[0039] refer to Figure 3 and Figure 4 The first guide rail 10 has a first guide rail wall 121, a second guide rail wall 122, and a third guide rail wall 123. The first guide rail wall 121 and the second guide rail wall 122 are arranged in a relative position transversely, and the third guide rail wall 123 is arranged longitudinally between the first guide rail wall 121 and the second guide rail wall 122. The guide rail groove 11 is surrounded by the first guide rail wall 121, the second guide rail wall 122, and the third guide rail wall 123. Specifically, the cross-sectional shape of the first guide rail 10 is H-shaped or h-shaped.
[0040] exist Figure 3 and Figure 4 In the guide rail structure shown, the first guide rail wall 121 and the second guide rail wall 122 are arranged in a relative position transversely and are substantially parallel to each other, and the third guide rail wall 123 is arranged longitudinally to connect the first guide rail wall 121 and the second guide rail wall 122, so as to form an H-shaped structure. In a specific structural scheme, the third guide rail wall 123 is perpendicular to the first guide rail wall 121 and the second guide rail wall 122. Further, the first guide rail can be made of H-shaped steel or I-shaped steel.
[0041] In one embodiment of the present application, part or all of the first guide rails 10 are used to guide the movement of the driving device 30. In one embodiment of the present application, two first guide rails 10 are arranged at intervals on one side of the car to guide the movement of the driving device 30 and the car frame 20. Figure 1 and Figure 2 As shown, in one embodiment, the self-propelled rail elevator is provided with two first guide rails 10 at intervals, and the two first guide rails 10 are used to guide the movement of the car frame 20 and the driving device 30. The driving device 30 is located above the car frame 20 to pull the car frame 20 to rise and fall.
[0042] In one embodiment of the present application, the self-propelled rail elevator further comprises a second guide rail, which is different from the first guide rail 10 and extends in the same direction as the first guide rail 10, and is used to guide the movement of the driving device 30. In this solution, the driving device and the car frame are guided by different guide rails.
[0043] In the embodiment of the present application, the support is detachably mounted on the car frame. The plurality of limiting rollers of the guide limiting device are all accommodated in the guide rail groove, and the plurality of limiting rollers on the support can be maintained and replaced by removing the support.
[0044] It should be understood that the limit roller of the guide limit device is a consumable part and needs regular maintenance and replacement. Since the limit roller of the guide limit device is installed in the guide rail groove and the hoistway space is limited, it becomes very difficult to disassemble and assemble the limit roller. In some structures, the entire car frame needs to be disassembled to disassemble and assemble the limit roller, which is a very large workload.
[0045] refer to Figure 6 In one embodiment of the present application, the guide limit device 40 is arranged near the top of the car frame 20 and near the bottom of the car frame 20. Figure 6 In the structure shown, two guide limit devices 40 are arranged near the top of the car frame 20 to cooperate with the two first guide rails 10 respectively, and two guide limit devices 40 are arranged near the bottom of the car frame 20 to cooperate with the two first guide rails 10 respectively. In the structure shown in this scheme, the guide limit devices 40 are arranged near the top and bottom of the car frame 20, which is convenient for relevant personnel to disassemble and assemble the guide limit devices from the top or bottom of the car frame.
[0046] Continue to refer Figure 7 In one embodiment of the present application, for the guide limit device 40 near the top of the car frame 20, the car frame 20 is provided with a limit groove 21 into which the support 41 can slide from top to bottom, and a bolt 22 is arranged on the upper half of the support 41 to fix the support 41 to the car frame 20. When the support is installed, the support 41 slides from top to bottom into the limit groove 21, and when it enters the predetermined position, the bolt 22 is installed to completely fix the support 41 to the car frame 20. Here, the bolt 22 and the limit groove 21 are used to fix the support 41 together. When the support is disassembled, the bolt 22 fixing the support is first removed, and then the support 41 is moved upward out of the limit groove 21. In the structure shown in this scheme, the bolt 22 is arranged in the upper half of the support 41, so it is closer to the top edge of the car frame 20, so that it is more convenient for relevant personnel to disassemble and assemble the bolt from the top of the car frame, thereby improving the convenience of disassembly and assembly.
[0047] In one embodiment of the present application, for the guide limiting device 40 located near the top of the car frame 20 , the limiting groove 21 is arranged at the bottom of the support 41 to limit the bottom edge of the support 41 .
[0048] Continue to refer Figure 8In one embodiment of the present application, for the guide limit device 40 near the bottom of the car frame 20, the car frame 20 is provided with a limit groove 21 into which the support 41 can slide from bottom to top, and a bolt 22 is arranged at the lower half of the support 41 to fix the support 41 to the car frame 20. When the support is installed, the support 41 is slid into the limit groove 21 from bottom to top, and when it enters the predetermined position, the bolt 22 is installed to completely fix the support 41 to the car frame 20. Here, the bolt 22 and the limit groove 21 are used to fix the support 41 together. When the support is disassembled, the bolt 22 fixing the support is first removed, and then the support 41 is moved downward out of the limit groove 21. In the structure shown in this scheme, the bolt 22 is arranged at the lower half of the support 41, so it is closer to the bottom edge of the car frame 20, so that it is more convenient for relevant personnel to disassemble and assemble the bolt from the bottom of the car frame, thereby improving the convenience of disassembly and assembly.
[0049] In one embodiment of the present application, for the guide limiting device 40 located near the bottom of the car frame 20 , the limiting groove 21 is arranged at the top of the support 41 to limit the top edge of the support 41 .
[0050] refer to Figure 7-Figure 9 In one embodiment of the present application, the support 41 is a plate-like structure, which is fitted on the mounting surface 23 of the car frame 20. A positioning plate 24 is fitted and fixed on the mounting surface 23, and the positioning plate 24 is provided with an oblique cut 241 facing the mounting surface 23 on the edge of the side close to the support 41, so as to form a limiting groove 21 for the edge of the support 41 to be embedded.
[0051] like Fig. 9 As shown, the support 41 and the positioning plate 24 are in a separated state. When installing, the support 41 is pushed upward into the limiting groove 21 at the top, and then the corresponding bolts are installed near the bottom. The lower edge of the positioning plate 24 is provided with an oblique cut 241 facing the mounting surface 23, and the limiting groove 21 is formed between the oblique cut 241 and the mounting surface 23 of the car frame 20.
[0052] In the present application, the limiting rollers of the guide limiting device are placed in the guide rail grooves. In the guide rail grooves, the limiting rollers in different directions respectively press the guide rail walls in the corresponding directions to limit the car frame to the first guide rail. By arranging the limiting rollers in the guide rail grooves, the space occupied by the elevator equipment around the car frame is reduced. On the other hand, the present application also optimizes the installation position and installation method of the guide limiting device, reduces the difficulty of disassembly and assembly, and makes the maintenance and replacement of the limiting rollers more convenient.
