DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figures 1 to 4As shown, a safety protection device for facilitating the assembly of an elevator car described in an embodiment of the utility model comprises a base 1; a servo motor 12 is fixedly connected to the top of the base 1; an electric telescopic rod 13 is fixedly connected to the output end of the servo motor 12; a collar 14 is fixedly connected to the output end of the electric telescopic rod 13; four multi-segment pull rods 15 are fixedly connected to the middle of the collar 14; the ends of the four multi-segment pull rods 15 are fixedly connected to suction cups 16. When working, the base 1 is placed inside the elevator car, and the side wall inside the elevator car can be installed. With the installation of the elevator side wall, the servo motor 12 can be started. With the start of the servo motor 12, the servo motor 12 will drive the electric telescopic rod 13 on the top of the servo motor 12 to perform servo rotation. When installing on a specified surface, the servo motor 12 can be started to allow the electric telescopic rod 13 to drive the collar 14 to rotate until the collar 14 drives the multi-segment pull rods 15 to rotate. The segment pull rod 15 is facing the wall to be installed. At this time, the multi-segment pull rod 15 is pulled. As the multi-segment pull rod 15 is pulled, the multi-segment pull rod 15 will drive the suction cup 16 to extend and retract back and forth. At this time, when the suction cup 16 extends to the side wall of the wall, the multi-segment pull rod 15 continues to be pulled until the suction cup 16 is adsorbed on the side wall of the elevator wall. When two or more walls need to be fixed, the servo motor 12 can be started again. As the servo motor 12 is started again, the ring 14 can be driven to rotate, so that the multi-segment pull rod 15 corresponds to the position of the wall, and then the wall is adsorbed and fixed by the suction cup 16. Through the above structure, the servo motor 12 can be started and the multi-segment pull rod 15 is pulled to achieve the fixation of the elevator wall, thereby reducing the situation where the elevator wall is unstable during the installation process, resulting in the elevator wall falling off and causing safety hazards.

[0025] Reference Figures 1 to 3 As shown, a first sliding ring 22 is slidably connected to the middle of one end of the multi-segment pull rod 15 near the end; a plurality of top rods 2 are fixedly connected to the middle of the first sliding ring 22; the plurality of top rods 2 are equidistantly distributed along the contour of the first sliding ring 22 and are bent; the ends of the plurality of top rods 2 are fixedly connected to gaskets 21; the gaskets 21 are made of flexible material. During operation, as the multi-segment pull rod 15 is pulled, the end of the multi-segment pull rod 15 will be extended and retracted. At this time, when the suction cup 16 is adsorbed on the wall of the elevator, the first sliding ring 22 is pulled. As the first sliding ring 22 slides in the middle of the multi-segment pull rod 15, the top rod 2 will gradually approach the wall of the elevator until the gasket 21 fits the wall of the elevator. At this time, the wall of the elevator can be further fixed and limited. Through the above structure, the plurality of gaskets 21 cooperate with the suction cup 16 to fix and limit the specified wall from multiple points, thereby further reducing the situation where the wall falls off during installation.

[0026] Reference Figure 1 and Figure 3As shown, the middle part of one end of the plurality of multi-section pull rods 15 close to the ring 14 is fixedly connected to two support plates 3; the two support plates 3 are symmetrically arranged; the middle parts of the two support plates 3 are rotatably connected to a roller 31; the top of the ring 14 is fixedly connected to a vertical rod 34; the middle part of the vertical rod 34 is slidably connected to a second sliding ring 33; a side wall of the first sliding ring 22 facing the support plate 3 is connected to a pull rope 32; the pull rope 32 extends to the bottom of the pull rope 32, and the end is fixedly connected to the bottom of the second sliding ring 33. When working, when it is necessary to fix the wall at multiple points, the first sliding ring 22 can be slid to allow multiple suction cups 16 and gaskets 21 to contact the wall, thereby The wall is fixed and limited. After the wall is installed, the second sliding ring 33 can be slid. As the second sliding ring 33 slides upward, the pull rope 32 at the bottom of the second sliding ring 33 can be straightened. At this time, the straightened pull rope 32 will slide in the middle of the roller 31 as the second sliding ring 33 slides in the middle of the vertical rod 34. At this time, multiple pull ropes 32 will synchronously drive multiple first sliding rings 22 to slide in the middle of the multi-section pull rod 15. At this time, multiple groups of gaskets 21 can be moved away from the elevator wall. Through the above structure, multiple gaskets 21 can be slid synchronously, thereby reducing the cumbersome steps that need to be operated one by one, and further increasing work efficiency.

[0027] Reference Figures 1 to 3 As shown, a support frame 4 is fixedly connected to the middle of the multi-section pull rod 15; the support frame 4 is located in the middle of the suction cup 16 and the first sliding ring 22, and is bent; a liquid storage capsule 41 is fixedly connected to the end of the support frame 4; the liquid storage capsule 41 is located above the suction cup 16; a needle 42 is fixedly connected to the middle of one of the push rods 2; the needle 42 is facing the liquid storage capsule 41, and when working, the liquid is filled in the liquid storage capsule 41, and then when the first sliding ring 22 slides, it can drive the push rod 2 to slide, and at this time when the push rod When sliding to the designated position, the needle 42 will contact the liquid storage capsule 41. When the needle 42 contacts the liquid storage capsule 41, the needle 42 will puncture the liquid storage capsule 41. At this time, the liquid inside the liquid storage capsule 41 will be sprayed onto the surface of the suction cup 16. At this time, as the suction cup 16 and the liquid come into contact, the adsorption capacity of the suction cup 16 on the elevator wall can be increased. Through the above structure, the adsorption capacity of the suction cup 16 on the wall can be further enhanced, thereby reducing the loosening caused by the weak adsorption between the suction cup 16 and the wall.

[0028] Reference Figure 1 and Figure 4As shown, a protective shell 5 is fixedly connected to the middle of the electric telescopic rod 13; the protective shell 5 is located near the bottom of the electric telescopic rod 13 and does not contact the base 1; the servo motor 12 is located inside the protective shell 5. During operation, as the installation work on the elevator wall proceeds and the acupuncture 42 punctures the liquid storage capsule 41, there will be more impurities and waste liquid around the working area of ​​the device. At this time, when the waste liquid and impurities are in contact with the servo motor 12 for a long time, the servo motor 12 will be damaged. At this time, by installing a protective shell 5 in the middle of the electric telescopic rod 13, and then allowing the protective shell 5 to surround the servo motor 12 in the middle, the servo motor 12 can be protected. At the same time, the heat emitted by the servo motor 12 during long-term operation will flow out from the bottom of the protective shell 5. Through the above structure, the servo motor 12 can be continuously protected, thereby reducing the damage caused by external impurities during the operation of the servo motor 12.

[0029] Reference Figure 4 As shown, a dustproof net 6 is fixedly connected to the bottom of the protective shell 5; the bottom of the dustproof net 6 is fixedly connected to the top of the base 1. When working, the heat generated by the servo motor 12 working for a long time can be dissipated by not contacting the bottom of the protective shell 5 with the top of the base 1. At this time, by installing the dustproof net 6 at the bottom of the protective shell 5 and contacting with the top of the base 1, external impurities can be tightly blocked. Through the above structure, the entry of external dust and impurities into the interior of the protective shell 5 can be reduced, which causes excessive accumulation of impurities in the protective shell 5, thereby affecting the operation of the servo motor 12.

[0030] Reference Figure 1 and Figure 3 As shown, a limiting plate 7 is fixed to the top of the vertical rod 34; the radius of the limiting plate 7 is larger than the radius of the vertical rod 34. During operation, by sliding the second sliding ring 33, a plurality of gaskets 21 can be uniformly recovered. At this time, by installing the limiting plate 7 on the top of the vertical rod 34, the second sliding ring 33 can be limited. Through the above structure, the second sliding ring 33 can be reduced from sliding out from the end of the vertical rod 34 due to sliding too high.

[0031] Reference Figure 1 and Figure 4 As shown, a non-slip pad 8 is fixed to the top of the base 1; the radius of the non-slip pad 8 is the same as the radius of the base 1. When working, the base 1 is placed inside the elevator, and then the modification is started to fix the wall. At this time, by installing the non-slip pad 8 at the bottom of the base 1, the friction between the bottom of the base 1 and the elevator floor can be increased, thereby reducing the shaking of the device during operation.

[0032] During operation, the base 1 is placed inside the elevator car, and the side wall inside the elevator car can be installed. As the side wall of the elevator is installed, the servo motor 12 can be started. As the servo motor 12 is started, the servo motor 12 will drive the electric telescopic rod 13 on the top of the servo motor 12 to perform servo rotation. When installing on a specified surface, the servo motor 12 can be started to allow the electric telescopic rod 13 to drive the ring 14 to rotate until the ring 14 drives the multi-segment pull rod 15 to face the wall to be installed. At this time, the multi-segment pull rod 15 is pulled. As the multi-segment pull rod 15 is pulled, the multi-segment pull rod 15 will drive the suction cup 16 to retract back and forth. At this time, when the suction cup 16 extends to the side wall of the wall, the multi-segment pull rod 15 is continued to be pulled until the suction cup 16 is adsorbed. On the side wall of the elevator wall, when it is necessary to fix two or more walls, the servo motor 12 can be started again. As the servo motor 12 is started again, the ring 14 can be driven to rotate, so that the multi-segment pull rod 15 corresponds to the position of the wall, and then the wall is adsorbed and fixed by the suction cup 16. As the multi-segment pull rod 15 is pulled, the end of the multi-segment pull rod 15 will retract. At this time, when the suction cup 16 is adsorbed on the wall of the elevator, the first sliding ring 22 is pulled. As the first sliding ring 22 slides in the middle of the multi-segment pull rod 15, the top rod 2 will gradually approach the wall of the elevator until the gasket 21 fits with the wall of the elevator. At this time, the wall of the elevator can be further fixed and limited. As the multi-segment pull rod 15 is pulled, the multi-segment pull rod 15 The end of the rod 15 will be extended and retracted. At this time, when the suction cup 16 is adsorbed on the wall of the elevator, the first sliding ring 22 is pulled. As the first sliding ring 22 slides in the middle of the multi-section pull rod 15, the top rod 2 will gradually approach the wall of the elevator until the gasket 21 fits with the wall of the elevator. At this time, the wall of the elevator can be further fixed and limited. When the wall needs to be fixed at multiple points, the first sliding ring 22 can be slid to allow multiple suction cups 16 and gaskets 21 to contact the wall, thereby fixing and limiting the wall. When the wall is installed, the second sliding ring 33 can be slid. As the second sliding ring 33 slides upward, the pull rope 32 at the bottom of the second sliding ring 33 can be straightened. At this time, the straightened pull rope 32 will move along with the second sliding ring 33 Slide in the middle of the vertical pole 34 and slide in the middle of the roller 31. At this time, multiple pull ropes 32 will synchronously drive multiple first sliding rings 22 to slide in the middle of the multi-section pull rod 15. At this time, multiple groups of gaskets 21 can be moved away from the elevator wall, and liquid is filled in the liquid storage capsule 41. Then, when the first sliding ring 22 slides, it can drive the top rod 2 to slide. At this time, when the top rod 2 slides to the specified position, the acupuncture 42 will contact the liquid storage capsule 41. When the acupuncture 42 contacts the liquid storage capsule 41, the acupuncture 42 will puncture the liquid storage capsule 41. At this time, the liquid inside the liquid storage capsule 41 will be sprayed onto the surface of the suction cup 16. At this time, as the suction cup 16 and the liquid come into contact, the adsorption capacity of the suction cup 16 on the elevator wall can be increased. As the installation work on the elevator wall proceeds,When the liquid storage capsule 41 is punctured by the needle 42, there will be more impurities and waste liquid around the working area of ​​the device. At this time, when the waste liquid and impurities are in contact with the servo motor 12 for a long time, the servo motor 12 will be damaged. At this time, by installing a protective shell 5 in the middle of the electric telescopic rod 13, and then letting the protective shell 5 surround the servo motor 12 in the middle, the servo motor 12 can be protected. At the same time, the heat emitted by the servo motor 12 for a long time will flow out from the bottom of the protective shell 5. The bottom of the protective shell 5 does not contact the top of the base 1, so the heat emitted by the servo motor 12 for a long time can be dissipated. At this time, by installing a dustproof net 6 at the bottom of the protective shell 5 and contacting the top of the base 1, the external impurities can be tightly blocked. By sliding the second sliding ring 33, multiple gaskets 21 can be uniformly recycled. At this time, by installing a limit plate 7 on the top of the vertical rod 34, the second sliding ring 33 can be limited. The base 1 is placed inside the elevator, and then the modification is started to fix the wall. At this time, an anti-slip pad 8 is installed at the bottom of the base 1. ,

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
