Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a plug - type safety guarantee structure for elevators. Background Technique

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two columns of rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. There are also step - type ones, where the tread plates are installed on the tracks and run continuously, commonly known as escalators or moving walkways, which are fixed lifting devices serving specified floors. A vertical elevator has a car that runs between at least two columns of vertical or inclined rigid guide rails with an inclination angle less than 15°. When the elevator runs between floors, it often needs to stop for people to get on and off. Due to the increase or decrease in the weight of the elevator caused by people getting on and off, the steel cable expands and contracts, resulting in the elevator shaking.

[0003] Regarding the above - mentioned and existing related technologies, the inventor believes that there are often the following defects: The traditional elevator car does not have a positioning device during actual operation. When the weight increases or decreases due to people getting on and off, the elevator shakes, which cannot meet the actual use requirements. Therefore, a plug - type safety guarantee structure for elevators is proposed for the above - mentioned problems. Summary of the Utility Model

[0010] Preferably, limiting grooves are formed on both sides of the through cavity inside the limiting rod, and first limiting blocks are slidably connected inside the limiting grooves. One side of each first limiting block is fixedly connected to the U-shaped positioning rod.

[0011] The effects achieved by the above components are as follows: The cooperation between the limiting grooves and the first limiting blocks increases the stability of the U-shaped positioning rod relative to the limiting rod, and further increases the stability of the elevator car.

[0012] Preferably, a threaded groove is formed inside the U-shaped positioning rod, and the threaded rod penetrates into the inside of the threaded groove.

[0028] The positioning device 3 includes four limiting rods 307 fixedly installed at the bottom of the first mounting plate 2, a U-shaped positioning rod 306 arranged between the limiting rods 307, a controller 305 fixedly installed at the bottom of the first mounting plate 2, two second mounting plates 302 fixedly installed at the bottom of the first mounting plate 2, and a biaxial motor 303 fixedly installed between the second mounting plates 302. Threaded rods 304 are fixedly installed on both output shafts on both sides of the biaxial motor 303;

[0029] The limiting device 4 includes second limiting blocks 401 arranged before and after the U-shaped positioning rod 306 and a limiting cavity 402 opened inside the second limiting blocks 401. The limiting cavity 402 is sleeved outside the U-shaped positioning rod 306 through the limiting cavity 402.

[0030] Specifically, a through cavity 308 is opened inside the limiting rod 307, and the U-shaped positioning rod 306 passes through the through cavity 308 into the inside of the limiting rod 307.

[0031] The accommodation of the U-shaped positioning rod 306 is realized through the setting of the through cavity 308, and the positioning of the elevator car 1 is realized by the U-shaped positioning rod 306 passing through the inside of the second limiting block 401, increasing the stability of the elevator when parked.

[0032] Specifically, limiting grooves 310 are opened on both sides of the through cavity 308 inside the limiting rod 307. A first limiting block 309 is slidably connected inside the limiting grooves 310. One side of the first limiting block 309 is fixedly connected to the U-shaped positioning rod 306.

[0033] The cooperation between the limiting grooves 310 and the first limiting block 309 increases the stability of the U-shaped positioning rod 306 relative to the limiting rod 307, thereby increasing the stability of the elevator car 1.

[0034] Specifically, a threaded groove 301 is opened inside the U-shaped positioning rod 306, and the threaded rod 304 passes through into the inside of the threaded groove 301

[0035] The cooperation between the threaded groove 301, the biaxial motor 303, and the threaded rod 304 realizes the pushing of the U-shaped positioning rod 306, so that the U-shaped positioning rod 306 passes through into the inside of the second limiting block 401 to increase the stability of the elevator car 1.

[0036] Specifically, first connecting plates 403 are fixedly installed on both sides of the second limiting block 401, and first bolts 404 are inserted inside the first connecting plates 403.

[0037] The cooperation between the first connecting plates 403 and the first bolts 404 realizes the installation of the second limiting block 401 relative to the building, facilitating the subsequent accommodation of the U-shaped positioning rod 306 to position the elevator car 1.

[0038] Specifically, two second connecting plates 5 are fixedly installed on both sides of the first mounting plate 2. A second bolt 6 is inserted through the interior of the second connecting plate 5, and the top of the second bolt 6 is fixedly connected to the bottom of the elevator car 1.

[0039] The installation and fixation of the first mounting plate 2 relative to the elevator car 1 are achieved through the cooperation between the second connecting plate 5 and the second bolt 6.

[0040] During use, place the first mounting plate 2 at the bottom of the elevator car 1 and fix the first mounting plate 2 to the bottom of the elevator car 1 through the second connecting plate 5 and the second bolt 6. After fixation, pick up the second limiting block 401 and pre-drill an installation hole inside the elevator shaft of the building to install the second limiting block 401 into the interior of the installation hole. At the same time, fix the second limiting block 401 relative to the building through the first connecting plate 403 and the first bolt 404. During actual use, when the elevator car 1 stops stably at the required floor and before the elevator door opens, drive the opening of the double-shaft motor 303 through the controller 305. Drive the threaded rod 304 to rotate through the double-shaft motor 303. Under the action of the thread groove 301, push the U-shaped positioning rod 306 to move towards the side close to the second limiting block 401 and penetrate into the limiting cavity 402. After the operation is completed, the elevator door opens for passengers to get on and off. After the passengers get on and off and the elevator door closes, drive the threaded rod 304 to reverse through the double-shaft motor 303. Then, under the action of the thread groove 301, the U-shaped positioning rod 306 moves towards the relatively close side, so that the U-shaped positioning rod 306 is withdrawn from the interior of the limiting cavity 402, enabling the elevator to move up and down.
