Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and particularly relates to a traction-driven automatic door mechanism applied to intelligent elevators. Background Technique

[0002] An elevator is a lifting mechanical device that transports people or goods up and down in a vertical passageway on a platform or semi-enclosed platform. It usually consists of a platform, control equipment, a motor, cables, and other auxiliary equipment. 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 for work. They are not intelligent and do not adapt to the development of society, so intelligent elevators have emerged.

[0004] An intelligent elevator is a lifting device integrated with 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 various functions such as automatic operation, automatic leveling, passenger counting, and wireless transmission. They not only improve construction efficiency but also effectively reduce construction costs. At the same time, their 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 the setting of the telescopic cylinder increases the overall longitudinal height of the cage, expanding the problem of interference in use, and the rotating chain has a relatively fast wear rate. The problem of excessive chain wear leads to the problem of slipping of the buckle, and there is a risk that the cage door will drop by one gear buckle due to its own weight. In the event of this problem, at the very least, the cage door will be skewed, and in severe cases, there is a problem that the sliding cage door may injure passing personnel.

[0008] Based on the above, further optimization and improvement are required. Content of the Utility Model

[0009] Aiming at the problems raised in the above background technique, the purpose of the present utility model is to provide a traction-driven automatic door mechanism applied to intelligent elevators.

[0010] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0011] A traction-driven automatic door mechanism applied to an intelligent elevator comprises a cage, wherein two door guide wheels are symmetrically mounted on the cage, a cage door is slidably mounted between the two door guide wheels, connection blocks are mounted on both sides of the bottom of the cage door, and rope buckles are mounted on the connection blocks;

[0012] Two traction machines are mirror-imaged on the top of the cage, a traction wheel is installed at the output end of the traction machine, slide rails are installed on both sides of the cage at the lower side of the traction wheel, a counterweight is slidably installed on the slide rail, a lifting ring is installed on the top of the counterweight, a traction rope is connected between the lifting ring and the rope buckle, and the traction rope is hung on the traction wheel;

[0013] A laser radar and a locking mechanism are installed inside the cage, and the sensing end of the laser radar covers the inner bottom plane of the cage where the cage door is installed. The locking mechanism includes a mounting frame installed on the top of the cage and a block installed on the inner side of the cage door. An electric push rod is installed in the mounting frame, and a lock tongue is installed at the output end of the electric push rod. The lock tongue passes through the mounting frame, and the position of the lock tongue corresponds to the block.

[0014] It is further defined that a buffer block is installed at the bottom of the cage door. Such a design reduces the impact force on the bottom of the cage when the cage door descends.

[0015] It is further defined that one side of the slide rail is L-shaped, and the counterweight block is provided with a U-shaped slot clamped on the slide rail. Such a design strengthens the sliding fit between the slide rail and the counterweight block, and ensures the stability of the lifting and sliding.

[0016] It is further defined that the connecting block is L-shaped, and the rope buckle is hingedly installed on the connecting block. With such a design, the L-shaped connecting block can prevent the cage door from tilting to a certain extent, and the hinged installation method of the rope buckle can better cooperate with the traction rope.

[0017] It is further defined that a fixing frame is installed inside the mounting frame, and the electric push rod is fixedly installed on the fixing frame. Such a design strengthens the position fixing effect of the electric push rod, thereby also strengthening the force effect of the output end of the electric push rod, and then strengthening the locking effect after the collision.

[0018] The beneficial effects of adopting the utility model are:

[0019] The structural design of the utility model uses a traction rope instead of a chain to pull the cage door. The traction rope has the same technical effect as the chain, but is not prone to the problem of tooth slip between the chain and the gear, which ensures the service life and has stronger safety performance.

[0020] With the structural design of the present utility model, under the perception of the lidar, it has the effect of preventing the cage door from injuring people. Under the effect of the locking mechanism, it can effectively prevent the equipment from starting when the cage door is not fully closed, and also ensures the stable closing of the cage door during operation, ensuring the safety effect.

[0032] To enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] As Figures 1 to 7 shown, a traction drive automatic door mechanism applied to an intelligent elevator of the present utility model includes a cage 1, two door guide wheels 2 are symmetrically installed on the cage 1, a cage door 3 is slidably installed between the two door guide wheels 2, connection blocks 4 are installed on both sides of the bottom of the cage door 3, and a rope buckle 5 is installed on the connection block 4;

[0034] Two traction machines 6 are mirror-installed on the top of the cage 1, a traction wheel 7 is installed at the output end of the traction machine 6, slide rails 8 are installed on both sides of the cage 1 below the traction wheel 7, a counterweight 9 is slidably installed on the slide rail 8, a hanging ring 10 is installed on the top of the counterweight 9, and a traction rope 11 is connected between the hanging ring 10 and the rope buckle 5, and the traction rope 11 is hung on the traction wheel 7;

[0035] A lidar 12 and a locking mechanism 13 are installed inside the cage 1. The sensing end of the lidar 12 covers the inner bottom plane of the cage 1 where the cage door 3 is installed. The locking mechanism 13 includes a mounting frame 131 installed on the inner top of the cage 1 and a blocking block 132 installed on the inner side of the cage door 3. An electric push rod 133 is installed inside the mounting frame 131, a locking tongue 134 is installed at the output end of the electric push rod 133, the locking tongue 134 penetrates through the mounting frame 131, and the position of the locking tongue 134 corresponds to the blocking block 132.

[0036] In this embodiment, when using a traction drive automatic door mechanism applied to an intelligent elevator, the traction machine 6 is started to drive the traction wheel 7 to rotate towards the counterweight 9. Under the effect of the counterweight 9, the traction rope 11 is pulled down, and then the connection block 4 connected to the other end of the traction rope 11 moves upward, thereby pulling the cage door 3 to move upward under the limit of the door guide wheel 2 to achieve the purpose of opening the door. On the contrary, when the traction wheel 7 rotates towards the rope buckle 5, the purpose of closing the door is achieved;

[0037] During the closing process of the cage door 3, the lidar 12 monitors the situation below the cage door 3 at all times. When a foreign object is found, a signal is transmitted to the central control system in time to control the traction machine 6 to stop running, so that the cage door 3 cannot descend further to prevent accidents. When the cage door 3 is completely closed, the locking mechanism 13 operates, and the electric push rod 133 drives the locking tongue 134 to move to the upper side of the blocking block 132, so that the cage door 3 cannot move upward anymore, preventing the cage door 3 from automatically opening during the lifting process. At the same time, when the electric push rod 133 drives the locking tongue 134 to operate and the electric push rod 133 cannot operate in place, it indicates that the end face of the locking tongue 134 is resisted, which further indicates that the cage door 3 is not closed in place, and a signal is given to the elevator not to operate to achieve the purpose of safety protection.

[0038] Preferably, a buffer block 14 is installed at the bottom of the cage door 3. Such a design reduces the impact force on the bottom of the cage 1 when the cage door 3 descends. In fact, the position, quantity or buffering measures of the buffer block 14 can also be considered according to specific circumstances.

[0039] Preferably, one side of the slide rail 8 is L-shaped, and the counterweight block 9 is provided with a U-shaped slot 15 clamped on the slide rail 8. Such a design strengthens the sliding fit between the slide rail 8 and the counterweight block 9 and ensures the stability of the lifting and sliding. In fact, the structure of the slide rail 8 and the counterweight block 9 can also be considered according to specific circumstances.

[0040] Preferably, the connecting block 4 is L-shaped, and the rope lock 5 is hingedly installed on the connecting block 4. With this design, the L-shaped connecting block 4 can prevent the cage door 3 from tilting to a certain extent, and the hinged installation method of the rope lock 5 can better cooperate with the traction rope 11. In fact, the structure of the connecting block 4 and the installation method of the rope lock 5 can also be considered according to specific circumstances.

[0041] Preferably, a fixing frame 135 is installed inside the mounting frame 131, and the electric push rod 133 is fixedly installed on the fixing frame 135. Such a design strengthens the position fixing effect of the electric push rod 133, thereby also strengthening the force effect of the output end of the electric push rod 133, and then strengthening the locking effect after the collision. In fact, the fixing structure of the electric push rod 133 can also be considered according to specific circumstances.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
