Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an anti-falling villa elevator. Background Art

[0002] A villa elevator is an elevator installed in a private residence and is only used by a single family member. It can also be installed in a building that is not used by a single family as a tool for a single family to enter their residence. Villa elevators are different from public elevators. They are used by a single family. Therefore, home elevators have higher requirements for safety protection, especially for the elderly or children in the family. If a sudden power outage or failure occurs while the elevator is in use, maximum safety protection is required for the family.

[0003] However, the existing villa elevators use a traction machine to lift the elevator car, and a brake structure is provided on the drive shaft of the traction machine. When braking, most of these villa elevators rely on various sensors to detect the speed of the villa elevator, and then drive the brake disc to move through a cylinder or a hydraulic cylinder to brake the villa elevator under the action of friction. After long-term use, electrical components are prone to various faults that lead to brake failure, which in turn causes the villa elevator car to fall rapidly and cause a safety accident. For this reason, we propose an anti-fall villa elevator. Utility Model Content

[0008] Preferably, it also includes a motor, which is arranged on the left end surface of the left vertical plate, the output shaft of the motor is fixedly connected to the left end of the mounting shaft, and the input end of the motor is electrically connected to the output end of the external controller, so that the anti-fall steel wire inside the wire drum can be retracted and released synchronously with the movement of the car.

[0009] Preferably, the braking mechanism includes a friction disc, a limit block, a guide rod, a limit groove and an adjusting disc. The guide rod is symmetrically arranged on the right end face of the vertical plate on the right side. Guide holes slidably connected to the guide rod are symmetrically provided at the front and rear ends of the adjusting disc. The limit blocks are slidably connected in the limit grooves evenly arranged on the left side of the adjusting disc. The left sides of the limit blocks are fixedly connected to the friction disc.

[0010] Preferably, a T-rod is slidably connected to the step hole arranged in the middle part of the limit block, and the right end of the T-rod is fixedly connected to the corresponding inner wall of the limit groove. The right end of the T-rod is movably sleeved with a spring, and the spring is located between the limit block and the corresponding inner wall of the limit groove, which can play a buffering role in the falling of the villa elevator car.

[0013] The utility model has the following advantages:

[0014] 1. This anti-fall villa elevator drives the turntable to rotate at high speed through the installation shaft. Under the action of centrifugal force, the driving block slides outward along the slide groove, and then the driving block cooperates with the notch on the inner wall of the driving ring and drives the driving ring to rotate. When the driving block slides out, the spring piece is stuck in the ratchet groove corresponding to the outer side of the driving block, which can prevent the driving block from sliding into the interior of the slide groove again, so that the driving ring rotates synchronously with the installation shaft. The driving ring drives the internal threaded sleeve to rotate through the connecting rod, and drives the adjusting disk to move to the left through the external threaded cylinder threadedly connected to the internal threaded sleeve until the friction disk contacts the brake disk. Under the limiting action of the limit block and the limit groove, the installation shaft is decelerated by friction until the installation shaft stops completely, thereby preventing the villa elevator car from continuing to fall. The villa elevator car can be locked without electrical drive, and the structure is safer and more reliable.

[0015] 2. This anti-fall villa elevator locks the villa elevator car through the contact between the friction disc and the brake disc. When locking, as the adjusting disc continues to move to the left, the spring between the limit block and the limit groove is gradually compressed, so that the friction force between the friction disc and the brake disc continues to increase, which can play a buffering role in the locking of the villa elevator car and reduce the impact force when the car falls and is locked.

The front and rear ends of the adjusting disc 25 are symmetrically provided with guide holes slidably connected to the guide rod 23, which can guide the adjusting disc 25. The limit blocks 22 are slidably connected in the limit grooves 24 evenly arranged on the left side of the adjusting disc 25. The left side of the limit block 22 is fixedly connected to the friction disc 21. The friction disc 21 corresponds to the position of the brake disc 11. The interior of the adjusting disc 25 is provided with an externally threaded tube 12. The step hole arranged in the middle of the limit block 22 is slidably connected with a T-shaped rod 221.

The driving mechanism 3 includes a turntable 31, an internal threaded sleeve 32, a driving ring 33 and a mounting seat 34. The turntable 31 is fixedly sleeved on the right end of its mounting shaft 8, and the lower end of the mounting seat 34 is fixedly connected to the corresponding leg 6 by bolts respectively. The interior of the mounting seat 34 is rotatably connected with the driving ring 33 through a bearing. The outer arc surface of the turntable 31 is symmetrically provided with sliding grooves 13, and the interior of the sliding grooves 13 is slidably connected with the driving blocks 14. The inner wall of the driving ring 33 is symmetrically provided with notches matching the driving blocks 14. The left side of the driving ring 33 is evenly provided with connecting rods, and the left ends of the connecting rods are fixedly connected to the internal threaded sleeves 32.

When the car 5 of the villa elevator falls rapidly, the rotation speed of the mounting shaft 8 increases instantly. Under the action of centrifugal force, the driving block 14 slides outward along the slide groove 13, and then the driving block 14 cooperates with the notch on the inner wall of the driving ring 33 and drives the driving ring 33 to rotate. When the driving block 14 slides out, the spring piece 15 is stuck in the ratchet groove corresponding to the outer side surface of the driving block 14, which can prevent the driving block 14 from sliding into the interior of the slide groove 13 again, so that the driving ring 33 rotates synchronously with the mounting shaft 8, and the driving ring 33 drives the internal threaded sleeve 32 to rotate through the connecting rod, and then drives the adjusting disk 25 to move leftward through the external threaded tube 12 threadedly connected to the internal threaded sleeve 32, and the car 5 of the villa elevator can be locked without electrical drive, and the structure is safer and more reliable.

[0033] The working principle of the anti-fall villa elevator is as follows: the elevator frame 1 is fixed to the shaft of the villa elevator, and the external traction machine drives the frame 4 and the car 5 to move up and down. At the same time, the external controller controls the motor 10 to rotate the installation shaft 8, so that the anti-fall wire 9 inside the wire drum 81 is retracted and released synchronously with the movement of the car 5. At this time, the installation shaft 8 rotates at a constant speed. Under the elastic force of the spring piece 15, the driving block 14 is always located in the slide groove 13 on the outer arc surface of the turntable 31. When the car 5 of the villa elevator falls rapidly, the rotation speed of the installation shaft 8 increases instantly. Under the action of centrifugal force, the driving block 14 slides outward along the slide groove 13, and then the driving block 14 cooperates with the notch on the inner wall of the driving ring 33 and drives the driving ring 33 to rotate. When the driving block 14 slides out, the spring piece 15 is stuck in the ratchet groove corresponding to the outer side surface of the driving block 14, which can prevent the driving block 14 from sliding into the inside of the slide groove 13 again. , so that the driving ring 33 rotates synchronously with the mounting shaft 8, and the driving ring 33 drives the internal threaded sleeve 32 to rotate through the connecting rod.
