Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and particularly relates to an electromagnetic linkage door mechanism applied to intelligent elevators. Background Art

[0002] An elevator is a lifting mechanical device that transports people or goods up and down in a vertical passageway, usually in the form of a platform or semi-enclosed platform. It generally consists of a platform, control equipment, a motor, cables, and other auxiliary equipment. Elevators can be classified 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 control its operation. This is not intelligent and does not adapt to the development of society, so intelligent elevators emerged.

[0004] An intelligent elevator is a lifting device integrated with advanced technologies, featuring intelligent control, high-efficiency operation, and low maintenance costs. It 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, passenger counting, and wireless transmission. This not only improves construction efficiency but also effectively reduces construction costs. At the same time, its intelligent control reduces the dependence on professional drivers and makes operation more convenient.

[0006] However, after on-site inspections by the applicant, it was found that the current landing doors used to protect the cage still need to be opened manually, which does not conform to the concept of full intelligence and thus requires optimization and improvement. Summary of the Utility Model

[0007] In view of the problems raised in the above background art, the purpose of the present utility model is to provide an electromagnetic linkage door mechanism applied to intelligent elevators.

[0008] To achieve the above technical objectives, the technical solution adopted by the present utility model is as follows:

[0009] An electromagnetic linkage door mechanism applied to intelligent elevators includes a mounting block installed on the top of the cage door. Wings are provided on both sides of the mounting block, and a first guide rod is installed between the two wings. A chute is provided on the mounting block, and two scraping blocks are placed in the chute. The tails of the two scraping blocks are slidably installed on the first guide rod, and a first spring is installed between each of the two wings and the corresponding scraping block.

[0010] The installation block is integrally connected with an angle block, an electromagnet is installed on the angle block, the output end of the electromagnet is V-shaped, a magnetic attraction block is matched and installed at the output end of the electromagnet, the upper end of the magnetic attraction block is in an inverted V shape, and the two scraping blocks are located on both sides of the sharp angle at the upper end of the magnetic attraction block. Second guide rods are installed at both ends of the magnetic attraction block, the lower ends of the second guide rods are connected with a landing door, a second spring is installed between the magnetic attraction block and the landing door, and the second spring is sleeved outside the second guide rods.

[0011] Further defined, the scraping block is integrally connected with an inner plate, a rectangular block is sleeved and installed on the scraping block, and a screw is installed between the rectangular block and the inner plate. With such a design, while realizing the stable installation of the scraping block, the distance between the inner plate and the rectangular block can be adjusted by adjusting the screw, and further the clamping force between the inner plate and the rectangular block on the installation block can be adjusted, so as to achieve the purpose of adjusting the sliding effect of the scraping block.

[0012] Further defined, a flannelette pad is installed on the contact surface between the scraping block and the magnetic attraction block. With such a design, when contacting, it can effectively clean the magnetic attraction surface of the magnetic attraction block and is not easy to scratch the magnetic attraction surface of the magnetic attraction block.

[0013] Further defined, a nut is threadedly connected to the lower end of the second guide rod. With such a design, by rotating the nut, the distance between the magnetic attraction block and the landing door at rest can be adjusted to ensure the adsorption effect.

[0014] Further defined, the angle block is provided with two waist-shaped holes, and the electromagnet is installed in the waist-shaped holes. With such a design, the installation adaptability of the electromagnet and the position matching effect with the magnetic attraction block are enhanced.

[0015] Beneficial effects of adopting the present utility model:

[0016] With the structural design of the present utility model, by controlling the operation of the electromagnet, it can be realized that while the cage door rises, the landing door is synchronously driven to rise, achieving the purpose of automatic opening. Anyway, the closing of the landing door can also be completed through this principle, which is relatively intelligent;

[0017] With the structural design of the present utility model, when the electromagnet approaches the magnetic attraction block, the scraping block will contact the magnetic attraction block first, cleaning the contact surface of the magnetic attraction block, preventing problems that stones and other impurities adhere to the contact surface of the magnetic attraction block in the construction site area, affecting the magnetic attraction connection effect, and the V-shaped contact surface of the magnetic attraction block is not easy to adhere to large stone particles, ensuring the practical effect.

Detailed implementation manners

[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 drawings and embodiments.

[0027] As Figures 1 to 5 shown, an electromagnetic linkage door mechanism applied to an intelligent elevator of the present utility model includes a mounting block 2 installed on the top of the cage door 1. Wing plates 3 are provided on both sides of the mounting block 2. A first guide rod 4 is installed between the two wing plates 3. A chute 5 is provided on the mounting block 2. Two scraping blocks 6 are placed in the chute 5. The tails of the two scraping blocks 6 are slidably installed on the first guide rod 4. A first spring 7 is installed between each of the two wing plates 3 and the scraping block 6;

[0028] The mounting block 2 is integrally connected with a corner block 8. An electromagnet 9 is installed on the corner block 8. The output end of the electromagnet 9 is V-shaped. A magnetic attraction block 10 is installed in a matching manner at the output end of the electromagnet 9. The upper end of the magnetic attraction block 10 is inverted V-shaped. The two scraping blocks 6 are located on both sides of the sharp corners of the upper end of the magnetic attraction block 10. Second guide rods 11 are installed at both ends of the magnetic attraction block 10. The lower ends of the second guide rods 11 are connected to a landing door 12. A second spring 13 is installed between the magnetic attraction block 10 and the landing door 12. The second spring 13 is sleeved outside the second guide rod 11.

[0029] In this embodiment, when using an electromagnetic linkage door mechanism applied to an intelligent elevator, when it is necessary to enter the cage, the electromagnet 9 is controlled to operate to generate suction force, which contacts the magnetic attraction block 10 that presses the second spring 13, and adsorbs the magnetic attraction block 10. Then, the cage door 10 rises, driving the landing door 12 to rise together, achieving the purpose of automatically opening the landing door 12;

[0030] When it is necessary to exit the cage from the landing door 12, the cage descends, causing the corner block 8 to descend. During the descent, the scraping block 6 first contacts the magnetic attraction block 10, and then under the action of force and the V-shaped structure of the contact surface with the magnetic attraction block 10, the scraping block 6 compresses the first spring 7 on the first guide rod 4 and moves towards both ends of the magnetic attraction block 10. In this action, the scraping block 6 cleans the contact surface of the magnetic attraction block 10, preventing impurities such as stone particles from existing on the magnetic attraction surface of the magnetic attraction block 10 and affecting the magnetic attraction cooperation effect with the electromagnet 9. The continuous descent of the corner block 8 causes the electromagnet 9 to press the magnetic attraction block 10, causing the magnetic attraction block 10 to compress the second spring 13 on the second guide rod 11. Under the reaction force of the second spring 13, the contact effect between the magnetic attraction block 10 and the electromagnet 9 is ensured. Then, the electromagnet 9 operates to generate suction force, and then the cage door 1 rises, driving the landing door 12 to rise, achieving the purpose of automatically opening the landing door 12.

[0031] Preferably, the scraping block 6 is integrally connected with an inner plate 14. The scraping block 6 is sleeved and installed with a rectangular block 15, and a screw 16 is installed between the rectangular block 15 and the inner plate 14. With this design, while achieving the stable installation of the scraping block 6, by adjusting the screw 16, the distance between the inner plate 14 and the rectangular block 15 can be adjusted, and further the clamping force between the inner plate 14 and the rectangular block 15 on the mounting block 2 can be adjusted, achieving the purpose of adjusting the sliding effect of the scraping block 6. In fact, the installation structure of the scraping block 6 in the sliding groove 5 can also be considered according to specific situations.

[0032] Preferably, a flannelette pad is installed on the contact surface between the scraping block 6 and the magnetic attraction block 10. With this design, when contacting, it can effectively clean the magnetic attraction surface of the magnetic attraction block 10 while not easily scratching the magnetic attraction surface of the magnetic attraction block 10. In fact, the structural style of the scraping block 6 can also be considered according to specific situations.

[0033] Preferably, the lower end of the second guide rod 11 is threadedly connected with a nut 17. With this design, by rotating the nut 17, the distance between the magnetic attraction block 10 and the landing door 12 at rest can be adjusted to ensure the adsorption effect. In fact, the connection structure between the second guide rod 11 and the landing door 12 can also be considered according to specific situations.

[0034] Preferably, the corner block 8 is provided with two waist-shaped holes 18, and the electromagnet 9 is installed in the waist-shaped holes 18. With this design, the installation adaptability of the electromagnet 9 and the position matching effect with the magnetic attraction block 10 are strengthened. In fact, the installation structure of the electromagnet 9 can also be considered according to specific situations.
