AI Technical Summary
When the support frame is about to move to the top or bottom of the support frame, the existing wall-mounted elevator cannot stop in time due to inertia, causing the support frame to hit the end point of the support frame, causing damage.
A wall-mounted lift is designed, using a limiting mechanism and a sensor to cooperate with the motor. When the sensor senses the top or bottom end of the support frame, the motor stops working. When the support frame moves inertia within the buffer zone, the fixing rod and spring provide buffering to avoid impact.
It effectively avoids the support frame impacting the end point of the support frame when it moves in an inertia, reduces damage to the support frame and improves the service life of the equipment.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The following is combined with Figure 1-6 This application is described in further detail.
[0025] A wall-mounted lift includes a support frame 10, a lifting mechanism and a support frame 2. The support frame 10 is fixedly arranged on a wall, the lifting mechanism is arranged on the support frame 10, a motor 12 is fixedly arranged on the support frame 10, the motor 12 is connected to the lifting mechanism, the lifting mechanism is connected to a fixed frame 18, and the support frame 2 is fixedly connected to the fixed frame 18. When in use, a staff member stands on the support frame 2 and starts the motor 12. The lifting mechanism moves with the support frame 2, and the staff member is moved to a high place by the support frame 2.
[0026] The lifting mechanism includes a chain 9, a sprocket 14 and a sliding frame 1. The support frame 10 is rotatably provided with a rotating rod 13, the motor 12 is connected to the rotating rod 13, the sprocket 14 is fixedly provided on the rotating rod 13, two sprockets 14 are provided on the rotating rod 13, and the two sprockets 14 are respectively provided on both sides of the rotating rod 13. The chain 9 is meshedly provided on the sprocket 14, and the bottom end of the support frame 10 is rotatably provided with a follower wheel 8, and the chain 9 is meshedly provided on the follower wheel 8.
[0027] The sliding frame 1 is provided with a moving wheel 19 for rotation, and a plurality of moving wheels 19 are provided on the sliding frame 1. The moving wheel 19 abuts against the support frame 10, and the fixed frame 18 is fixedly connected to the sliding frame 1, and the sliding frame 1 is connected to the chain 9. When the motor 12 is started, the rotating rod 13 rotates, the sprocket 14 rotates with the rotating rod 13, and the chain 9 rotates under the action of the sprocket 14. When the chain 9 rotates, the sliding frame 1 moves on the support frame 10, and the moving wheel 19 keeps the sliding frame 1 stable during the movement of the sliding frame 1.
[0028] A limiting mechanism is provided on the support frame 10. Two limiting mechanisms are provided on the support frame 10. The two limiting mechanisms are respectively provided at two ends of the support frame 10. The limiting mechanisms are at a certain distance from the end points of the support frame 10. The limiting mechanism includes a connecting plate 4, a sensor 3 and a fixing rod 16. The sensor 3 is fixedly provided on the supporting frame 10. The sensor 3 is fixedly provided on the connecting plate 4. The fixing plate is fixedly provided on the fixing frame 18. The sensing head of the sensor 3 faces the fixing rod 16. The sensor 3 is electrically connected to the motor 12.
[0029] When the support frame 2 is about to move to the lowest end or the highest end of the support frame 10, the fixed rod 16 on the fixed frame 18 first moves in front of the sensor 3. When the sensing head of the sensor 3 senses the existence of the fixed rod 16, the motor 12 stops working, the rotating rod 13 and the sprocket 14 stop rotating, the chain 9 stops rotating along with the sprocket 14, and the support frame 2 stops moving. At this time, the support frame 2 is still some distance away from the highest end or the bottom end of the support frame 10. This distance can buffer the inertial movement of the support frame 2, and can reduce the risk of the support frame 2 colliding with the support frame 10 due to inertial movement.
[0030] A mounting plate 7 is fixedly provided on the support frame 10. Two mounting plates 7 are provided on the support frame 10. The limiting mechanism is between the two mounting plates 7. A fixed tube 6 is fixedly provided on the side of the mounting plate 7 close to the support frame 2. A spring 15 is fixedly provided in the fixed tube 6. One end of the spring 15 is fixedly connected to a moving tube 5. The moving tube 5 is sleeved on the fixed tube 6. When the support frame 2 moves by inertia due to stopping the support frame 2, the fixed rod 16 presses against the moving tube 5, and the spring 15 plays a buffering role.
[0031] The motor 12 is provided with an encoder 11, which can accurately set the parking height distance of the support frame 2, so that the support frame 2 can be accurately stopped at a suitable height. The fixed rod 16 is fixedly connected with a fixed block 17. When the support frame 2 continues to move due to inertia, the fixed block 17 is pressed against the moving tube 5. The area of the fixed block 17 is larger than the area of the fixed rod 16. The fixed block 17 increases the contact area with the moving tube 5, and increases the stability of the fixed block 17 against the moving tube 5.
[0032] The implementation principle of this embodiment is: when the support frame 2 is about to move to the top or bottom of the support frame 10, the fixed block 17 on the fixed frame 18 first moves to the front of the sensing head of the sensor 3. When the sensor 3 senses the existence of the fixed block 17, the motor 12 stops working and the lifting mechanism stops moving. At this time, the support frame 2 is still a certain distance away from the top or bottom of the support frame 10, and this distance can buffer the inertial movement of the support frame 2. When the support frame 2 is buffering, the fixed rod 16 contacts the moving tube 5, and the spring 15 assists in buffering the support frame 2. Under buffering, it is not easy for the support frame 2 to hit the end point of the support frame 10, so that the support frame 2 is not easy to be damaged, thereby achieving the effect of making the support frame 2 not easy to be damaged.
