Description

Technical Field

[0001] This utility model relates to the field of villa elevator technology, and in particular to a steel belt counterweight frame for a compact villa elevator and the villa elevator itself. Background Technology

[0002] The counterweight is a crucial component of an elevator, primarily used to support the elevator car and balance its weight, ensuring safe elevator operation. Counterweights are generally divided into steel belt counterweights and wire rope counterweights. Steel belt counterweights use steel belts to traction the elevator, while wire rope counterweights use steel ropes to traction the elevator.

[0003] A search revealed a compact right-angle door steel belt villa elevator with authorization announcement number CN217201524U, comprising a car system, a traction system, a counterweight system, and a guide rail system. The traction system includes a traction machine, traction ropes, and traction sheaves. The car system includes a car frame with four sides, a car housed within the car frame, and two car return rope sheaves mounted on the top of the car. The car system also includes a center-opening door device on one side of the car frame and a side-opening door device on the other side perpendicular to the center-opening door device. The counterweight system is located in the hoistway relative to the center-opening door device, and the center of the center-opening door device, the center of the counterweight system, and the center of the car frame are on the same straight line.

[0004] However, the steel belt counterweight frame in the aforementioned steel belt villa elevator has a relatively fixed structure, making it inconvenient to quickly assemble, use, disassemble, maintain, and replace. This causes trouble and inconvenience for later maintenance of the steel belt counterweight frame, and it is also inconvenient to adjust the number of counterweights used as needed, as well as the distance between the two steel belt pulleys as needed, resulting in poor flexibility and limiting the scope of application of the device. Therefore, we propose a steel belt counterweight frame and villa elevator for compact villa elevators to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A steel belt counterweight frame for a compact villa elevator includes two vertical beams 1, a lower beam 2, and an upper beam 3. The lower beam 2 and the upper beam 3 are fixedly connected to the bottom and top of the two vertical beams 1, respectively. Two steel belt wheels 7 are provided on the top of the upper beam 3.

[0025] Furthermore, refer to Figure 1 and Figure 2As shown, the adjustment and disassembly mechanism 8 includes two detachable mounting plates 801 fixedly connected to the top of the upper beam 3. Vertical plates 803 are fixedly connected to the inner sides of both mounting plates 801, and bearings 805 are fixedly fixed to the inner sides of both vertical plates 803. The same rotating shaft 804 is fixedly sleeved within the inner rings of the two bearings 805. Two steel pulleys 7 are detachably fixedly connected to the outer sides of the rotating shaft 804. Screws 802 are threadedly connected to the top of the mounting plates 801, and the mounting plates 801 are fixedly connected to the top of the upper beam 3 by screws 802. The outer sides of the rotating shaft 804 are slidably sleeved on two mounting rings 810, and the outer sides of the mounting rings 810 are fixedly sleeved on... A fixed ring 808 is provided, and a steel pulley 7 is movably sleeved on the outside of the mounting ring 810 and abuts against the fixed ring 808. The top and bottom of the rotating shaft 804 are provided with several threaded grooves 806. The top and bottom of the mounting ring 810 are each threaded with two screws 807. The four screws 807 are threaded into the corresponding threaded grooves 806. A movable ring 809 is slidably sleeved on the outside of the mounting ring 810.

The four long screws 811 are threaded into the corresponding threaded grooves 812.

[0026] Using the above method: The steel pulley 7 is fitted onto the outside of the mounting ring 810 and abuts against the fixed ring 808. The movable ring 809 is then fitted on, and the long screw 811 is screwed into the threaded groove 812 of the fixed ring 808, thus fixing the steel pulley 7 onto the mounting ring 810. Then, the two mounting rings 810 and the steel pulley 7 are fitted onto the outside of the rotating shaft 804. The distance between the two steel pulleys 7 is adjusted according to actual needs. After adjustment, the four screws 807 are tightened, so that the four screws 807 are threaded into the corresponding threaded grooves 806, thus fixing the steel pulley 7 onto the rotating shaft 804. Finally, the rotating shaft 804 is connected between the two bearings 805. The mounting plate 801 and the vertical plate 803 are fixed using screws 802, thus allowing the two steel pulleys 7 to be rotatably mounted on the top of the upper beam 3. Simultaneously, by reversing the above steps, the steel pulley 7 can be disassembled for maintenance and replacement.

[0027] Furthermore, refer to Figure 1 and Figure 4 As shown, the clamping mechanism 5 includes a slider 56, a connecting groove 55 opened on one side of the vertical beam 1, and a pressure plate 51 placed between the two vertical beams 1. The two sliders 56 are respectively fixedly connected to the two sides of the counterweight 6. The sliders 56 are slidably sleeved in the corresponding connecting grooves 55. The top two sides of the pressure plate 51 are fixedly connected to ear plates 53. Two screws 52 are threadedly connected to one side of the ear plates 53. Several threaded grooves 54 are opened on one side of the vertical beam 1. The four screws 52 are respectively threadedly sleeved in the corresponding threaded grooves 54.

[0028] Using the above scheme: The lower beam 2 is connected to the bottom of the two vertical beams 1 by a fixing screw. The slider 56 and the counterweight 6 are slid into the space between the two vertical beams 1 and the lower beam 2 through the connecting groove 55. According to the actual needs, the corresponding number of counterweights 6 are placed between the two vertical beams 1. When the weight of the multiple counterweights 6 reaches the required level, the pressure plate 51 is placed on top of the uppermost counterweight 6, and the screw 3 52 is tightened so that the screw 3 52 is screwed into the threaded groove 3 54 of the corresponding height. This fixes the multiple counterweights 6 between the two vertical beams 1, the lower beam 2 and the pressure plate 51. Finally, the upper beam 3 is fixed to the top of the two vertical beams 1 by a fixing screw.

[0029] Furthermore, refer to Figure 1 and Figure 3 As shown, the connecting mechanism 4 includes an upper plate 44 and a lower plate 41 fixedly connected to one side of the vertical beam 1. An insert block 48 is fixedly connected to the top of the lower plate 41. A through groove 43 is opened on the top of the guide block 42. The insert block 48 is movably inserted into the through groove 43. A screw 45 is threadedly connected to the top of the upper plate 44. The upper plate 44 is fixedly connected to the top of the insert block 48 by the screw 45. The guide block 42 is fixedly arranged between the upper plate 44, the lower plate 41 and the insert block 48. A threaded groove 46 is threadedly connected to the top of the insert block 48. The screw 45 is threadedly connected into the threaded groove 46.

[0030] The above solution involves aligning the through groove 43 of the guide block 42 with the insert block 48, placing the guide block 42 on top of the lower plate 41 and fitting it onto the outside of the insert block 48, and finally tightening the screw 45 so that the screw 45 is screwed into the threaded groove 46. This fixes the guide block 42 between the upper and lower plates and the insert block 48, and also facilitates the later disassembly and replacement of the guide block 42 with greater wear.

[0031] This utility model embodiment also discloses a villa elevator, including the steel belt counterweight frame for villa elevators as described above, such as the villa elevator structure described in a compact right-angle door steel belt villa elevator in Chinese Patent No. CN217201524U.

[0032] In this utility model, during use, the lower beam 2 is connected to the bottom of the two vertical beams 1 via a fixing screw. The slider 56 and the counterweight 6 are slid into the space between the two vertical beams 1 and the lower beam 2 via the connecting groove 55. According to actual needs, a corresponding number of counterweights 6 are placed between the two vertical beams 1. When the weight of multiple counterweights 6 reaches the required level, the pressure plate 51 is placed on top of the uppermost counterweight 6, and the screw 3 52 is tightened so that the screw 3 52 is screwed into the threaded groove 3 54 of the corresponding height. This fixes multiple counterweights 6 between the two vertical beams 1, the lower beam 2 and the pressure plate 51. Finally, the upper beam 3 is fixed to the top of the two vertical beams 1 via the fixing screw.

[0033] Place the steel pulley 7 on the outside of the mounting ring 810 and abut it against the fixed ring 808. Then, put on the movable ring 809 and screw the long screw 811 into the threaded groove 812 of the fixed ring 808 to fix the steel pulley 7 on the mounting ring 810. Next, put the two mounting rings 810 and the steel pulley 7 on the outside of the rotating shaft 804. Adjust the distance between the two steel pulleys 7 as needed. After adjustment, tighten the four screws 807 so that the four screws 807 are threaded into the corresponding threaded grooves 806 to fix the steel pulley 7 on the rotating shaft 804. Finally, connect the rotating shaft 804 between the two bearings 805 and fix the mounting plate 801 and the vertical plate 803 with the screws 802. Then, the two steel pulleys 7 can be rotated and set on the top of the upper beam 3. At the same time, by reversing the above steps, the steel pulley 7 can be disassembled for maintenance and replacement.

[0034] Finally, align the through groove 43 of the guide block 42 with the insert block 48, then place the guide block 42 on top of the lower plate 41 and fit it on the outside of the insert block 48. Finally, tighten the screw 45 so that the screw 45 is screwed into the threaded groove 46, thereby fixing the guide block 42 between the upper and lower plates and the insert block 48. This also facilitates the disassembly and replacement of the guide block 42 with greater wear in the future.
