Description
Technical Field
[0001] The present application relates to the technical field of elevator equipment, and in particular to a double-car landing adjustment device. Background Art
[0002] With the development of economy and urbanization, the shortage of urban land resources has led to a rapid increase in the number of high-rise and super high-rise buildings in cities. This has also put forward higher requirements for elevator technology. Traditional elevator technology can no longer adapt to urbanization development, so double-car elevators have emerged as the times require.
[0003] Existing landing adjustment devices for carriages have a simple structure, a small installation space, and the adjustment and transmission are separated, requiring a relatively large transmission space. Depending on the load and environment, the weights of the upper and lower carriages are asymmetrical and prone to sliding. There are also fixed forms without an adjustment structure, with a relatively low cost and unable to adapt to floors with different landing heights. Summary of the Utility Model
[0004] In order to improve the problems of separated transmission and adjustment, inconvenient adjustment and maintenance, and inapplicability to floors with different landing heights, the present application provides a double-car landing adjustment device.
[0005] The double-car landing adjustment device provided by the present application adopts the following technical solutions:

[0014] Optionally, the fasteners include a connecting shaft and an end cap. The end cap is installed on the external connection seat, and the connecting shaft passes through the long swing arm / short swing arm, the external connection seat and the end cap and is locked and matched.
[0015] By adopting the above technical solution, the external connection seat is fastened on the fixed beam, the long swing arm and the short swing arm pass through the connecting shaft, and the connecting shaft and the external connection seat are fastened by using the end cap, so that the long swing arm and the short swing arm can rotate around the axis of the connecting shaft.

[0017] By adopting the above technical solution, spacers are arranged on both sides of the long swing arm and the short swing arm to reduce the mutual influence during rotation, and a shaft sleeve is sleeved between the long swing arm and the short swing arm for easy self-lubrication. An O-ring is also installed on the shaft sleeve to play a good dust-proof role and reduce the occurrence of the situation that dust enters and affects the rotation at the intersection of the long swing arm and the short swing arm.
[0018] Optionally, a limit switch is further installed at the bottom of the fixed beam for monitoring the extreme positions of the linear bearing block sliding on the shaft core.
[0019] By adopting the above technical solution, with the limit switch set, during the lifting and lowering of the upper and lower double carriages, the linear bearing block slides along the shaft core to the extreme positions on both sides, and can be promptly stopped in case of a malfunction or accident, ensuring safety.

Detailed implementation mode
[0033] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 drawings.
[0034] The embodiment of the present application discloses a double-carriage landing adjustment device.
[0035] Referring to Figure 1 , it includes a transmission mechanism 18, a lifting mechanism 19, a suspension sliding mechanism 20, a fixed beam 24 and an external connection seat 10; the transmission mechanism 18 is installed on the fixed beam 24 and is used to drive the suspension sliding mechanism 20 to slide on the fixed beam 24; the suspension sliding mechanism 20 is installed between the fixed beams 24 and is used to drive the lifting mechanism 19 to move along the length direction of the fixed beam 24; the lifting mechanism 19 is installed on the suspension sliding mechanism 20 and is used to adjust the distance between the upper and lower carriages; the external connection seat 10 is installed on the fixed beam 24 and serves as a fulcrum for the deflection of the lifting mechanism 19.
[0036] As shown in Figure 5 , an extreme position limit switch 21 is also installed at the bottom of the fixed beam 24 and is used to monitor the extreme position of the linear bearing seat 3 sliding on the shaft core 7. There are three extreme position limit switches 21 in total, which are respectively arranged on both sides and the middle position of the overall structure.
[0037] As shown in Figure 4 , the transmission mechanism 18 includes a reduction motor 1, a rack 5 and a gear 6. The rack 5 is fixed on the fixed beam 24, the gear 6 meshes with the rack 5, the extending end of the reduction motor 1 is fixed on the gear 6, the reduction motor 1 is arranged on the fixed beam 24 in a staggered manner, the reduction motor 1 is a worm and gear reduction motor 1 with a self-locking function, the extending end of the worm and gear reduction motor 1 is rotationally matched with the suspension sliding mechanism 20. After being driven by the worm and gear reduction motor 1, the gear 6 is driven to rotate. Since the rack 5 is welded and fixed on the fixed beam 24 and the gear 6 rolls on the rack 5, the suspension sliding mechanism 20 moves along the length direction of the fixed beam 24.
[0038] As shown in Figure 2As shown in the figure, the hanging sliding mechanism 20 is composed of a fixed seat 2, a linear bearing seat 3, a buffer pad 4 and a shaft core 7. The fixed seats 2 are equidistantly fixed between adjacent fixed beams 24. There are three fixed seats 2. The fixed seats 2 at both ends are used to limit the linear bearing seat 3. The shaft core 7 is rotatably arranged on the fixed seat 2, and the linear bearing seat 3 is slidably arranged on the shaft core 7. The side surface of the linear bearing seat 3 is in contact with the end surface of the fixed beam 24, which improves the stability of the linear bearing seat 3 during sliding. The worm and gear reduction motor 1 is fastened to the linear bearing seat 3. As the gear 6 rolls on the rack 5, the linear bearing seat 3 and the worm and gear motor move together along the axis direction of the shaft core 7. There are 4 buffer pads 4. The buffer pads 4 are fixedly installed on the shaft cores 7 opposite to each other on both sides of the fixed seat 2, and the buffer pads 4 are fixed on both sides of the fixed seat 2 in the middle of the shaft core 7. When the linear shaft side seat moves along the axis of the shaft core 7 to the fixed seat 2 in the middle, it plays a role of buffer protection.
[0039] Participate Figure 2 As shown in the figure, the lifting mechanism 19 includes a long swing arm 8 and a short swing arm 9; one end of the long swing arm 8 is rotatably arranged on the linear bearing seat 3, the other end of the long swing arm 8 is rotatably arranged on the short swing arm 9, and the end of the short swing arm 9 away from the long swing arm 8 is rotatably matched with the external connection seat 10. The intersecting end of the short swing arm 9 and the external connection seat 10 are fastened by a fastener 22. The fastener 22 includes a connecting shaft 16 and a shaft end cover 17. The shaft end cover 17 is installed on the external connection seat 10. The connecting shaft 16 passes through the long swing arm 8 / short swing arm 9, the external connection seat 10 and the shaft end cover 17 and is locked and matched. The long swing arm 8 moves closer to or away from each other with the linear bearing seat 3, so as to realize the adjustment of the distance between the upper and lower carriages and adapt to various floors with different floor levels.
[0040] Refer to Figure 3 As shown in the figure, the long swing arm 8 and the linear bearing seat 3 are connected by a short pin shaft 15, and the short swing arm 9 and the long swing arm 8 are connected by a long pin shaft 11. There are two long swing arms 8 and two short swing arms 9. The long swing arm 8 and the short swing arm 9 are connected by a rotating part 23. The rotating part 23 includes a shaft sleeve 12, a spacer 13 and an O-ring 14. The shaft sleeve 12 is slidably sleeved between the long swing arm 8 and the short swing arm 9, and the shaft sleeve itself has a lubricating effect, which is convenient for the long swing arm 8 and the short swing arm 9 to rotate along with the long pin shaft 11. The O-ring 14 is sleeved on the shaft sleeve 12 to reduce dust from entering the rotating part. The spacer 13 is integrally formed on the long swing arm 8 and the short swing arm 9. The spacers 13 on both sides of the long swing arm 8 and the short swing arm 9 reduce the mutual influence on the transmission efficiency during transmission. The shaft sleeve 12 is sleeved in the through holes opened on the long swing arm 8 and the short swing arm 9.
[0041] The implementation principle of a double-carriage landing adjustment device in an embodiment of this application is as follows: After the worm and worm gear reduction motor 1 is driven, the protruding shaft of the worm and worm gear reduction motor 1 drives the gear 6 to roll on the rack 5, and the adjacent linear bearing seats 3 approach or move away from each other, causing the adjacent long swing arms 8 to deflect. As a result, the upper and lower carriages on the fixed beam 24 expand or contract the adjacent spacing. In cooperation with the deflection of the short swing arm 9, it is applicable to floors with different landing heights. The limit switch 21 can stop the displacement distance position of the linear bearing seat 3, and the worm and worm gear reduction motor 1 has a self-locking function, improving the locking performance and ensuring the overall safety. The transmission mechanism 18 has a simple and reliable structure and high transmission efficiency. The transmission mechanism 18, the suspension sliding mechanism 20, and the lifting mechanism 19 leave a large installation space, facilitating adjustment and maintenance.
