DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A construction elevator with a protective function comprises a guide rail frame 1 and a car 2 slidably arranged on the guide rail frame 1, two mutually parallel protective plates 13 are arranged inside the car 2, the two protective plates 13 are perpendicular to the bottom of the car 2, and a distance is left between the two protective plates 13 to form a passenger space, at least one lifting damper is fixedly connected to the protective plate 13, an airbag 14 is fixedly arranged on the protective plate 13, and the airbags 14 on the two protective plates 13 are arranged oppositely, and the protective plate 13 is also fixedly connected to a plurality of binding components, the binding components include two straps 15, and the straps 15 are bypassed around the airbags 14.

[0021] When the elevator of the present invention is in use, the protection plate 13 can be used to protect the construction workers. Specifically, when the construction workers are unstable or about to fall due to the shaking of the car 2, they can hit the airbag 14, which can prevent the construction workers from falling and causing injuries on the one hand, and on the other hand, the airbag 14 can effectively reduce the impact force and protect the construction workers. On the other hand, when the car 2 is at risk of falling or hitting the top, the construction workers can use the straps 15 to tie themselves to the protection plate 13. During the rapid acceleration or deceleration process, the construction workers will drive the protection plate 13 to move synchronously through the straps 15. Because the protection plate 13 is connected to a lifting damper, the lifting damper can hinder the movement of the protection plate 13, thereby constraining the position of the protection plate 13 and the construction workers, and preventing the construction workers from directly impacting the top or bottom of the car 2, effectively realizing the protection of the construction workers. Multiple binding components can protect multiple construction workers at the same time.

[0022] The present invention can effectively protect the construction workers when they are about to fall, or when the car 2 is about to hit the top or fall, thereby fully ensuring the safety of the construction workers.

[0023] In order to fully and stably tie up the construction workers, the two straps 15 of the binding assembly cross each other in an X shape, and both ends of the straps 15 are fixedly connected to the protection plate 13, and the position where the straps 15 are fixedly connected to the protection plate 13 is staggered from the airbag 14. The two straps 15 are in a cross shape, and when the construction workers enter between the straps 15 and the protection plate 13, the two straps 15 can limit the construction workers from all directions, thereby fully preventing the construction workers from impacting the top or bottom of the car 2 when an accident occurs in the car 2, and realizing effective protection for the construction workers.

[0024] The specific structure of the lifting damper is as follows: the lifting damper includes a moving rod 11 and two fixed rods 8 fixed on the inner wall of the car 2, and the fixed rod 8 is perpendicular to the bottom of the car 2, and a slide 9 extending along the length direction is opened on the fixed rod 8, and the two slides 9 are arranged opposite to each other, and the two ends of the moving rod 11 are respectively extended into the two slides 9, and one end of the moving rod 11 inside the slide 9 is connected to the end of the slide 9 through a spring 10, and the protective plate 13 is fixedly connected to the moving rod 11. When the car 2 is about to hit the top or fall, the construction workers will move to the top or bottom of the car 2 under the action of inertia, and in the process, the protection plate 13 will be driven to move synchronously, and then the protection plate 13 will drive the moving rod 11 to move synchronously, so that the moving rod 11 moves into the slide 9 on one of the fixed rods 8. During the process, the moving rod 11 will squeeze the spring 10 to compress the spring 10, and when the spring 10 is compressed, it can hinder the movement of the moving rod 11, thereby achieving the effect of hindering the movement of the protection plate 13, and then the construction workers' movement speed is slowed down with the help of the straps 15 to prevent the construction workers from hitting the top or bottom of the car 2.

[0025] In order to facilitate the connection between the moving rod 11 and the protective plate 13, a gap is left between the two fixed rods 8 of the lifting damper, and the moving rod 11 is fixedly connected with a connecting rod 12, which passes through the gap and is fixedly connected to the protective plate 13. Each protective plate 13 is connected to two lifting dampers, and the connecting rods 12 in the two lifting dampers are respectively connected to two opposite edge positions of the protective plate 13.

[0026] In order to facilitate the transportation of some higher construction objects, the top of the car 2 can be opened. On this basis, in order to further protect the construction workers and the construction objects being transported and prevent them from falling from the top of the car 2 due to special reasons, a plurality of mutually parallel soft belts 3 are arranged on the top of the car 2. The soft belts 3 can effectively block the construction objects and construction workers and prevent them from accidentally jumping out from the open position on the top of the car 2. On the other hand, the soft belts 3 also have a certain deformation ability, which is convenient for transporting higher construction objects.

[0027] If the soft belt 3 is deformed to the maximum extent and still cannot block the construction personnel or construction objects, early warning measures or preventive measures should be taken quickly. In order to accurately sense the deformation extent of the soft belt 3, a tension sensor 7 is connected to each end of the soft belt 3. All tension sensors 7 are electrically connected to a feedback controller, and the feedback controller is connected to the main control device of the elevator. The tension sensor 7 can monitor the tension generated during the deformation of the soft belt 3, and then determine whether the soft belt 3 has deformed to the maximum extent. The feedback controller transmits the sensing data of the tension sensor 7 to the main control device of the elevator, and the car 2 can be quickly stopped and locked when the soft belt 3 is deformed to the maximum extent, so as to quickly eliminate the risk.

[0028] The specific arrangement of the tension sensor 7 is as follows: a plurality of cavities 4 for accommodating the tension sensor 7 are provided on the side wall of the car 2, the cavity 4 is provided with an opening 5 passing through the inner wall of the car 2, a pull rope 6 is fixedly connected to the end of the soft belt 3, the pull rope 6 passes through the opening 5 into the cavity 4, and is fixedly connected to the sensing end of the tension sensor 7.

[0029] In order to further protect the construction personnel and construction items entering the car 2, a buffer support assembly is provided at the bottom of the car 2. The buffer support assembly includes a support plate 16 and an elastic plate 17 arranged up and down, and the elastic plate 17 is fixedly arranged at the bottom of the car 2. An insulating plate 18 is also fixedly arranged between the elastic plate 17 and the bottom of the car 2. By providing the buffer support assembly, when the construction personnel or construction items enter the car 2, the elastic plate 17 can be used to achieve the effect of shock absorption and energy absorption, thereby protecting the construction items and construction personnel, and the insulating plate 18 can prevent the construction personnel or construction items from being insulated.

[0030] In a specific embodiment of the present invention, a construction elevator with a protective function includes a guide rail frame 1 and a car 2 slidably arranged on the guide rail frame 1, two parallel protective plates 13 are arranged inside the car 2, the two protective plates 13 are perpendicular to the bottom of the car 2, and a distance is left between the two protective plates 13 to form a passenger space, the protective plates 13 are fixedly connected to at least one lifting damper, an airbag 14 is fixedly arranged on the protective plates 13, and the airbags 14 on the two protective plates 13 are arranged opposite to each other, the protective plates 13 are also fixedly connected to a plurality of binding components, the binding components include two straps 15, the straps 15 bypass the airbags 14, the two straps 15 of the binding components cross each other in an X shape, both ends of the straps 15 are fixedly connected to the protective plates 13, and the position where the straps 15 are fixedly connected to the protective plates 13 is staggered with the airbags 14. The two straps 15 are in a cross shape. When the construction workers enter between the straps 15 and the protection plate 13, the two straps 15 can limit the construction workers from all directions, so as to fully prevent the construction workers from impacting the top or bottom of the car 2 when an accident occurs in the car 2, and effectively protect the construction workers. The lifting damper includes a moving rod 11 and two fixed rods 8 fixedly arranged on the inner wall of the car 2, and the fixed rods 8 are perpendicular to the bottom of the car 2. The fixed rods 8 are provided with slideways 9 extending along the length direction, and the two slideways 9 are arranged oppositely. The two ends of the moving rod 11 extend into the two slideways 9 respectively, and the moving rod 11 is connected to the end of the slideway 9 through a spring 10 at one end inside the slideway 9, and the protection plate 13 is fixedly connected to the moving rod 11. When the car 2 is about to hit the top or fall, the construction workers will move to the top or bottom of the car 2 under the action of inertia, and the protection plate 13 will be driven to move synchronously in the process, and then the protection plate 13 will drive the moving rod 11 to move synchronously, so that the moving rod 11 moves into the slide 9 on one of the fixed rods 8. In the process, the moving rod 11 will squeeze the spring 10, causing the spring 10 to compress, and when the spring 10 is compressed, it can hinder the movement of the moving rod 11, thereby achieving the effect of hindering the movement of the protection plate 13, and then the construction workers' movement speed is slowed down with the help of the strap 15 to prevent the construction workers from hitting the top or bottom of the car 2. There is a gap between the two fixed rods 8 of the lifting damper, and the moving rod 11 is fixedly connected with a connecting rod 12, which passes through the gap and is fixedly connected to the protection plate 13. Each protection plate 13 is connected to two lifting dampers, and the connecting rods 12 in the two lifting dampers are respectively connected to two opposite edge positions of the protection plate 13. A plurality of parallel soft belts 3 are arranged on the top of the car 2. The soft belt 3 can effectively block construction objects and construction workers, preventing them from accidentally jumping out from the open position on the top of the car 2. On the other hand, the soft belt 3 also has a certain deformation ability, which is convenient for transporting higher construction objects.A tension sensor 7 is connected to each end of the soft belt 3, and all tension sensors 7 are electrically connected to a feedback controller, which is connected to the main control device of the elevator. The tension sensor 7 can monitor the tension generated during the deformation of the soft belt 3, and then determine whether the soft belt 3 has deformed to the maximum extent. The feedback controller transmits the sensing data of the tension sensor 7 to the main control device of the elevator, and the car 2 can be quickly stopped and locked when the soft belt 3 is deformed to the maximum extent, so as to quickly eliminate the risk. A plurality of cavities 4 for correspondingly accommodating the tension sensors 7 are opened on the side wall of the car 2, and the cavity 4 is provided with an opening 5 that passes through the inner wall of the car 2. The end of the soft belt 3 is fixedly connected with a pull rope 6, and the pull rope 6 passes through the opening 5 into the cavity 4 and is fixedly connected to the sensing end of the tension sensor 7.
