Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of elevators, and particularly relates to a flip door mechanism with a counterweight applied to an intelligent elevator. Background Art
[0002] An elevator is a lifting mechanical device for carrying people or goods up and down in a vertical passageway, usually consisting of a platform, a control device, a motor, cables, and other auxiliary devices. Elevators can be divided into various types, such as fixed, mobile, rail-guided, articulated boom, scissor lift, etc., and are widely used in construction, logistics, aerial work, and other fields. With the development of technology, elevators are constantly evolving towards intelligence and high efficiency, improving work efficiency and safety;
[0003] Currently, common elevators are equipped with a dedicated driver operating inside the elevator to operate the elevator, which is not intelligent and does not adapt to the development of society. Therefore, intelligent elevators have emerged;
[0004] An intelligent elevator is a lifting device integrating advanced technologies, with advantages such as intelligent control, high-efficiency operation, and low maintenance costs, and is widely used in various industrial and civil construction projects.
[0005] Through digital and intelligent upgrades, intelligent elevators have achieved multiple functions such as automatic operation, automatic leveling, number monitoring, and wireless transmission, not only improving construction efficiency but also effectively reducing construction costs. At the same time, its intelligent control also reduces the dependence on professional drivers, making the operation more convenient.
[0006] Due to the trend towards intelligence and automation, the opening of the cage door has also been improved automatically. Commonly, a telescopic cylinder is directly used to connect with the cage door, or a gear motor is used in combination with a chain rotation to achieve the purpose of opening and closing the cage door;
[0007] However, after on-site inspection, the applicant found that because there is a distance between the exit position of the cage and the floor, the length of the pedal used to connect the two cannot be fixed. Therefore, it is difficult to control the length of the pedal when it extends during automatic latching, and there is also a problem of hitting the edge of the floor when the pedal extends horizontally. Therefore, manual latching is often required, but manual latching reduces its intelligence, so optimization and improvement are needed. Summary of the Utility Model
[0008] Aiming at the problems raised in the above background art, the purpose of the present utility model is to provide a flip door mechanism with a counterweight applied to an intelligent elevator.
[0009] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:
[0010] A flip - door mechanism with a counterweight applied to an intelligent lift, comprising a cage equipped with a traction mechanism. A door frame is provided at the outlet end of the cage. Door guide wheels are installed on both sides of the upper and lower ends of the door frame. A cage door is installed in the door frame through the door guide wheels. A traction buckle connected to the output end of the traction mechanism is installed beside the cage door. When the traction mechanism operates, it pulls the cage door to move up and down in the door frame;
[0011] Bearing seats are installed on both sides of the bottom inside the cage. A rotating shaft is rotatably installed in the two bearing seats together. A pedal is fixedly installed at the position of the rotating shaft between the two bearing seats. The front end of the pedal is lapped on the inner side of the cage door. Counterweight columns are installed at both ends of the rotating shaft.
[0012] Further defined, the traction mechanism includes a traction motor. The output end of the traction motor is connected to a traction wheel. A traction rope is connected between the traction wheel and the traction buckle. With such a design, controlling the forward and reverse rotation of the traction motor can achieve the lifting of the cage door, and the installation and use are simple, convenient and fast.
[0013] Further defined, the counterweight column is fixedly installed at the end of the rotating shaft through a locking screw. With such a design, it is beneficial for disassembly and replacement, so as to better form a cooperation with the weight of the pedal.
[0014] Further defined, the front end of the pedal is a slope. With such a design, while the overall appearance is better, when the pedal flips and adheres to the inner bottom of the cage, the slope can also be used to more conveniently lift and flip the pedal back to its original position.
[0015] Further defined, when the front end of the pedal is lapped on the inner side of the cage door, the counterweight column is vertically downward as a whole. With such a design, under the effect of gravity, it is ensured that the pedal will not flip beyond the limit.
[0016] Advantages of adopting the utility model:
[0017] With the structural design of the utility model, by using the self - weight of the pedal, when the cage door is completely lowered, the pedal can directly lap on the floor under the effect of its own weight. When the cage door rises, it can also resist the rise of the cage door. Until the cage door is closed, it laps on the inner wall of the cage door under gravity, which is beneficial for the next floor lapping. Without manual effort, the use effect is good, achieving the purpose of intelligence;
[0018] With the structural design of the utility model, under the effect of the counterweight column, when the pedal is subjected to the impact force of the rising cage door, it will not be forced to flip beyond the vertical line of 90°, which is not conducive to the next automatic lapping. The counterweight column plays a role in ensuring normal operation. Description of the drawings

[0023] The main element symbols are explained as follows:
[0024] Traction mechanism 1; cage 2; door frame 3; door guide wheel 4; cage door 5; traction buckle 6; bearing seat 7; rotating shaft 8; pedal 9; counterweight column 10;
[0025] Traction motor 101; traction wheel 102. Specific embodiments
[0026] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the attached drawings and embodiments.
[0027] As shown in Figure 1 , Figure 2 , Figure 3 An embodiment of a turning door mechanism with a counterweight applied to an intelligent lift of the present utility model includes a cage 2 equipped with a traction mechanism 1. A door frame 3 is provided at the outlet end of the cage 2. Door guide wheels 4 are installed on both sides of the upper and lower ends of the door frame 3. A cage door 5 is installed in the door frame 3 through the door guide wheels 4. A traction buckle 6 connected to the output end of the traction mechanism 1 is installed beside the cage door 5. When the traction mechanism 1 operates, it pulls the cage door 5 to move up and down in the door frame 3;
[0028] Bearing seats 7 are installed on both sides of the inner bottom of the cage 2. A rotating shaft 8 is rotatably installed together in the two bearing seats 7. A pedal 9 is fixedly installed at the position of the rotating shaft 8 between the two bearing seats 7. The front end of the pedal 9 is lapped on the inner side surface of the cage door 5. Counterweight columns 10 are installed at both ends of the rotating shaft 8.
[0029] In this embodiment, when a flip door mechanism with a counterweight applied to an intelligent elevator is used, after the elevator moves into position, the traction mechanism 1 operates, so that the cage door 5 moves down under its own weight, thereby opening the exit end of the cage 2 close to the floor. When the cage door 5 continues to descend to the position of the pedal 9, the pedal 9 begins to move down with the cage door 5 under its own weight because it touches the descent of the cage door 5. When the cage door 5 is completely descended, the pedal 9 is also overlapped on the floor under the effect of gravity. Because it is overlapped, it can be used as long as the distance between the cage 2 and the floor is not greater than the length of the pedal 9, and the adaptability is good.
[0030] When the pedal 9 is used up, the traction mechanism 1 drives the cage door 5 to rise. Under this power, the cage door 5 touches the lower side of the pedal 9, and then continues to drive the pedal 9 to rise. The pedal 9 therefore moves in an upward oblique direction with the rotating shaft 8 as the axis. When the front end of the pedal 9 moves and contacts the inner side of the cage door 5, the counterweight column 10 allows the pedal 9 to continue to maintain contact until the cage door 5 is completely closed. The pedal 9 is in a state of overlapping the inner side of the cage door 5, which is convenient for overlapping on the floor when the cage door 5 is opened next time.
[0031] Preferably, the traction mechanism 1 includes a traction motor 101, the output end of the traction motor 101 is connected to a traction wheel 102, and a traction rope is connected between the traction wheel 102 and the traction buckle 6. With this design, the lifting and lowering of the cage door 5 can be achieved by controlling the forward and reverse rotation of the traction motor 101. The installation and use are simple, convenient and fast. In fact, the structure of the traction mechanism 1 can also be considered according to specific circumstances.
[0032] Preferably, the counterweight column 10 is fixedly installed on the end of the rotating shaft 8 by a locking screw. Such a design is convenient for disassembly and replacement, so as to better cooperate with the weight of the pedal 9. In fact, the installation method of the counterweight column 10 can also be considered according to specific circumstances.
[0033] Preferably, the front end of the pedal 9 is an inclined surface. Such a design not only improves the overall appearance, but also allows the pedal 9 to be more conveniently lifted and flipped back to its original position when it is flipped over and attached to the inner bottom of the cage 2. In fact, the structural shape of the pedal 9 can also be considered according to specific circumstances.
[0034] Preferably, when the front end of the pedal 9 overlaps the inner side of the cage door 5, the counterweight column 10 is vertically downward as a whole. Such a design ensures that the pedal 9 will not flip over and over under the effect of gravity. In fact, the gravity coordination state between the pedal 9 and the counterweight column 10 can also be considered according to specific circumstances.
[0035] The above embodiments are only used to exemplarily illustrate the principles and effects of the present utility model, rather than to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
