Description

Technical Field

[0001] The invention relates to the technical field of elevator accident protection, in particular to an elevator accident protection device. Background Art

[0002] When an elevator falls unexpectedly, passengers should remain calm and take a series of standardized protective actions to protect their safety to the greatest extent. Keep your back close to the inner wall of the elevator, use the inner wall of the elevator as a protection for the spine, and reduce the impact of the elevator car falling on the spine. Keep your knees bent to withstand the heavy impact pressure, touch the ground with your toes, and try to keep on tiptoeing. This posture helps to alleviate the impact during the fall and reduce the damage to the legs and feet.

[0003] Earthquakes can damage the electrical system of an elevator, including control lines and drive motors. Damage to the electrical system may cause the elevator to lose control and suddenly stop or fall. People living in earthquake-prone areas need to regularly organize elevator accident prevention drills to improve their own safety protection skills. Although the elevator car in the drill can manually control the elevator's descent speed to simulate the scene of the elevator falling when encountering an earthquake or other emergency, most elevator cars lack relevant drill protection devices. For some users with weak protection skills, the elevator car lacks a structure to guide users to standardize protective actions, which is not conducive to users conducting elevator accident safety protection drills. Summary of the invention

[0004] The object of the present invention is to provide an elevator accident protection device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An elevator accident protection device, comprising:

[0007] Car;

[0008] A bottom guard plate is fixed to the inner bottom surface of the car, and two pedals 1 and 2 are hingedly connected to the top surface of the bottom guard plate, and the pedals 1 and 2 are used to drive the exercise user to move toward the side wall of the car;

[0009] Two side guard plates 1 are fixed on both sides of the interior of the car, respectively, and the side guard plates 1 include two movable plates 1 hinged to each other, and a backrest plate 1 which is hinged on the top of one of the movable plates 1 and is slidably engaged with the side guard plates 1;

[0010] A second side guard plate is fixed to the rear side of the car, the second side guard plate comprises two movable plates hinged to each other, and a backrest plate second is hinged at the top of one movable plate second and is slidably engaged with the second side guard plate;

[0011] The first movable board and the second movable board are used to drive the user's knees to maintain a bent posture, and the first backrest board and the second backrest board are used to support the user's back and assist the user's back to move downward to complete the knee bending action;

[0012] A plurality of gas cylinders are used to provide gas source power to drive the bottom guard plate, the side guard plate 1 and the side guard plate 2 to complete the protective action;

[0013] The section partition frame is used to partially protect the users in the car.

[0014] Furthermore, pillars are fixed at two corner positions inside the car, and the side guard plate 1 and the side guard plate 2 are fixedly connected to the pillars.

[0015] Furthermore, a clamping assembly is provided between the backrest plate 1 and the side guard plate 1, and between the backrest plate 2 and the side guard plate 2.

[0016] Furthermore, the bottom end of the movable plate 1 is hinged to the side guard plate 1, and the bottom of the side guard plate 1 is embedded and fixed with an extrusion airbag 1 and a support airbag 1 which are interconnected, and an overflow valve 1 is installed on the outer side of the extrusion airbag 1 and the support airbag 1.

[0017] Furthermore, the bottom end of the movable plate 2 is hinged to the side guard plate 2, and the bottom of the side guard plate 2 is embedded and fixed with an extrusion airbag 2 and a support airbag 2 which are interconnected, and an overflow valve 2 is installed on the outer side of the extrusion airbag 2 and the support airbag 2.

[0018] Furthermore, two lifting airbags 1 and 2 are embedded and fixed on the top surface of the bottom guard plate, wherein the lifting airbag 1 is arranged below the pedal 1, and the lifting airbag 2 is arranged below the pedal 2.

[0019] Furthermore, the gas cylinder is connected to and fixed with a gas pipe with a built-in electromagnetic valve, the lifting airbag 1 and the lifting airbag 2 are both connected to and fixed with the gas pipe, and a pedal 3 is fixed on the top surface of the bottom guard plate.

[0020] Further, the interval partition frame includes:

[0021] A support frame, the support frame comprising a cross bar slidably connected to the side guard plate, and longitudinal bars are fixed at both ends of the cross bar;

[0022] A plurality of support rods fixed to the bottom of the longitudinal rods;

[0023] Two screw rods are rotatably connected to the inside of the side guard plate 1 and are used to drive the cross bar to move up and down.

[0024] Furthermore, the support rod comprises a plurality of connecting blocks which are rotatably connected to each other, and the connecting block at the top end of the support rod is fixedly connected to the longitudinal rod.

[0025] Furthermore, two motors for driving the screw to rotate are fixed to the bottom of the side guard plate 1, and two storage boxes for storing the connection blocks are fixed to the bottom of the bottom guard plate.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Pedal 1 and Pedal 2 are hinged on the inner bottom surface of the car. When the elevator car simulates an accidental fall, the gas cylinder supplies gas to the lifting airbag 1 and the lifting airbag 2 through the gas pipe. The expanded lifting airbag 1 and the lifting airbag 2 push the pedal 1 and the pedal 2 upward, so that the pedal 1 and the pedal 2 drive the user's body to move in the direction of the side guard plate 1 and the side guard plate 2, which is convenient for reminding the user to lean his back against the side guard plate for protection drills. While the pedals 1 and 2 rotate, the user's body on the pedals 1 and 2 has a tendency to tilt away from the pedal 3, which helps to separate users in different pedal positions and prevent people from colliding with each other during elevator accident drills to a certain extent.

[0028] 2. The lifting airbag (including lifting airbag 1 and lifting airbag 2) is connected with the supporting airbag (including supporting airbag 1 and supporting airbag 2) and the squeezing airbag (including squeezing airbag 1 and squeezing airbag 2) through a pipeline, so that the lifting airbag in the expanded state can transfer part of the gas to the supporting airbag and the squeezing airbag. The volume expansion of the squeezing airbag will push the two mutually hinged movable plates (including movable plate 1 and movable plate 2) to rotate and extend the side guard plates (including side guard plates 1 and side guard plates 2), guiding the user to keep the knees bent to achieve the effect of protecting the elevator from falling accidents;

[0029] The expanded volume of the support airbag will support the user's heel. At this time, both pedal one and pedal two are in an inclined state. The low end of the pedal (including pedal one and pedal two) can easily accommodate the support airbag, so that the support airbag can flexibly support the user's heel. The high end of the pedal is in contact with the forefoot, prompting the user to complete the foot pad protection action. When the user's foot steps on the inclined pedal, the pedal will drive the user's body to tilt and fit tightly against the side guard plate, making it convenient to use the side guard plate to support the user's back and spine.

[0030] 3. The motor drives the screw to rotate and drive the interval partition frame from the bottom of the car to the vicinity of the user's chest, separating the users standing in different areas from the users' upper body positions, and further preventing users in different pedal areas from squeezing and contacting each other. During the upward movement of the longitudinal rod of the interval partition frame, the multiple connecting blocks at the bottom of the longitudinal rod rotate and unfold in the vertical direction under the action of their own gravity, making it convenient for the user to lean on the support rod composed of multiple connecting blocks. At the same time, the heel of the user on pedal three can step on the upturned end of pedal one. Because the bottom support of pedal one is supported by lifting airbag one, the upturned pedal one can move up and down within a range, which helps to support and buffer the impact force on the heel position of the user standing on pedal three, thereby achieving that the heels and backs of users at different positions inside the car have support structures, guiding users to standardize protective actions while protecting the safety of users' drills.

DETAILED DESCRIPTION

[0041] 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.

[0042] For example, see Figure 1-9In an embodiment of the present invention, an elevator accident protection device includes a car 100, a bottom guard plate 200 is fixed to the inner bottom surface of the car 100, and two pedals 1 210 and 220 are hinged on the top surface of the bottom guard plate 200. The pedals 1 210 and 220 are used to drive the drill user to move toward the side wall of the car 100. Side guard plates 1 300 are fixed on both sides of the interior of the car 100. The side guard plates 1 300 include two movable plates 1 310 hinged to each other. The top of one movable plate 1 310 is hinged with a backrest plate 1 320 slidably connected to the side guard plates 1 300. The rear side of the interior of the car 100 is fixed with a side guard plate 2 400. The side guard plate 2 400 includes two The movable panels 410 are hinged to each other, and the top of the movable panel 410 is hinged with a backrest panel 420 which is slidably connected to the side guard panel 400. The movable panels 1 310 and 410 are used to drive the user's knees to maintain a bent position. The backrest panel 1 320 and 420 are used to support the user's back and assist the user's back to move down to complete the knee bending action. A plurality of gas cylinders 500 are fixed to the bottom of the bottom guard panel 200 to provide gas source power to drive the bottom guard panel 200, the side guard panel 1 300 and the side guard panel 2 400 to complete the protective action. The top surface of the bottom guard panel 200 is embedded with an interval partition frame 600 to partially protect the user in the car 100.

[0043] Specifically, by installing a bottom guard plate 200 and a side guard plate inside the car 100, 12 different standing areas are divided on the bottom guard plate 200, so that the user is warned to stand in the predetermined position for protection drills during the drill. During the accidental falling of the car 100, the gas cylinder 500 delivers gas to the lifting airbag, the supporting airbag and the squeezing airbag through the pipeline. The expansion of the lifting airbag will drive pedal 1 210 and pedal 2 220 to flip toward the side wall of the car 100, so that the user's body can be driven to lean against the side guard plate so that the side guard plate can support the user's back and spine. The expansion of the supporting airbag supports the user's heel position so that the user's heel has a flexible protection structure during the process of stepping on the foot. The expansion of the squeezing airbag causes the two adjacent movable plates to rotate and extend out of the side guard plate, driving the user's knees to keep a bent posture to achieve the effect of protecting against elevator falling accidents, guiding users to standardize protective actions while protecting the safety of users' drills.

[0044] like Figure 3 and Figure 4 As shown, in this embodiment, pillars 110 are fixed at two corner positions inside the car 100 , and the side guard plate 1 300 and the side guard plate 2 400 are fixedly connected to the pillars 110 .

[0045] In this embodiment, the column 110 enables the side guard plate 1 300 and the side guard plate 2 400 to be fixed at the inner rear position of the car 100 through the column 110, thereby improving the stability of the side guard plates including the side guard plate 1 300 and the side guard plate 2 400 fixed inside the car 100.

[0046] like Figure 6 and Figure 7 As shown, in this embodiment, two lifting airbags 1 230 and 240 are embedded and fixed on the top surface of the bottom guard plate 200. The lifting airbag 1 230 is arranged below the pedal 1 210, and the lifting airbag 2 240 is arranged below the pedal 2 220. The gas cylinder 500 is connected to and fixed with an air pipe 510 with a built-in solenoid valve. The lifting airbags 1 230 and 240 are both connected and fixed to the air pipe 510, and a pedal 3 250 is fixed on the top surface of the bottom guard plate 200.

[0047] In this embodiment, when the car 100 accidentally falls, the solenoid valve inside the gas pipe 510 opens, and the gas cylinder 500 supplies compressed gas to the inside of the lifting airbag 1 230 and the lifting airbag 2 240 through the gas pipe 510, thereby causing the volume of the lifting airbag 1 230 to expand and push the pedal 1 210 upward, and the volume of the lifting airbag 2 240 to expand and push the pedal 2 220 upward. The inclination of the pedal 1 210 and the pedal 2 220 prompts the user's body to lean against the side guard plate, and at the same time enables the user's soles to step on the pedals including the pedal 1 210 and the pedal 2 220, and the user's heels are suspended on the pedals, guiding the user to standardize the foot protection movements and the movement of leaning the back against the inside of the car 100.

[0048] like Figure 4 and Figure 5 As shown, in this embodiment, the bottom end of a movable plate 310 is hinged to a side guard plate 300, and an extrusion airbag 330 and a support airbag 340 which are interconnected are embedded and fixed at the bottom of the side guard plate 300, and an overflow valve 342 is installed on the outer side of the extrusion airbag 330 and the support airbag 340.

[0049] In this embodiment, a receiving groove 350 for accommodating a movable plate 310 and a backrest plate 320 is provided on the inner side of the side guard plate 300, and the supporting airbag 340 is connected and fixed with the squeezing airbag 330 through a connecting tube 341. During the process of the squeezing airbag 330 expanding in volume, the two hinged movable plates 310 rotate and extend out of the side guard plate 300, and at the same time, the backrest plate 320 will move downward along the receiving groove 350 synchronously with the movable plate 310 hinged thereto, and the downwardly moved backrest plate 320 will move downward a short distance synchronously with the body to satisfy the user's knee bending.

[0050] like Figure 4 and Figure 6As shown, in this embodiment, the bottom end of a movable plate 410 is hinged to the side guard plate 400, and the bottom of the side guard plate 400 is embedded with an extrusion airbag 430 and a support airbag 440 that are interconnected. Overflow valves 442 are installed on the outer sides of the extrusion airbag 430 and the support airbag 440.

[0051] In this embodiment, a receiving groove 450 for accommodating a movable plate 410 and a backrest plate 420 is provided on the inner side of the side guard plate 400, and the supporting airbag 440 is connected and fixed to the extrusion airbag 430 through a connecting tube 441. During the expansion of the volume of the extrusion airbag 430, the two hinged movable plates 410 rotate and extend out of the side guard plate 400, and at the same time, the backrest plate 420 will move downward along the receiving groove 450 synchronously with the movable plate 410 hinged thereto, and the downward moving backrest plate 420 will move downward a short distance synchronously with the body to satisfy the user's knee bending requirement.

[0052] like Figure 4-6 As shown, in the embodiment, the overflow valve (including overflow valve 1 342 and overflow valve 2 442) can discharge part of the gas inside the squeeze airbag and the support airbag after the pressure is increased into the interior of the car 100, which is convenient for emergency use when the gas is oxygen. After the support airbag is hit by the user's heel, it will discharge unsealed gas and then cover and support the user's heel position, thereby improving the protection effect.

[0053] like Figure 5 and Figure 6 As shown, in the present embodiment, when the user steps on the supporting airbag 1 340 and the supporting airbag 2 440 with his heels due to the shaking of the elevator falling, the air pressure inside the supporting airbag 1 340 and the squeezing airbag 1 330 which are connected to each other will increase, thereby causing part of the gas to be released from the overflow valve 1 342 on the supporting airbag 1 340 and the squeezing airbag 1 330 to the interior of the car 100. Oxygen can be contained inside the gas cylinder 500, so that the oxygen released into the interior of the car 100 can be used by the user. Similarly, the oxygen inside the supporting airbag 2 440 and the squeezing airbag 2 430 can also be released from the overflow valve 2 442 to the car 100 for use, thereby realizing the release of the oxygen generated during the elevator accident protection process to the car 100 for use.

[0054] like Figure 5 and Figure 6 As shown, in this embodiment, a snap-in assembly 700 is provided between the backrest plate 1 320 and the side guard plate 1 300 , and between the backrest plate 2 420 and the side guard plate 2 400 .

[0055] In this embodiment, sliding grooves 710 are provided on both sides of the interior of the accommodating groove 1 350 and the accommodating groove 2 450, and clamping columns 720 are fixed on both sides of the top of the backrest board 1 320 and the backrest board 2 420. When the backrest board including the backrest board 1 320 and the backrest board 2 420 moves along the accommodating groove including the accommodating groove 1 350 and the accommodating groove 2 450, the clamping column 720 slides inside the sliding groove 710, so that the backrest board can slide on the side guard plate, and the backrest board cannot be separated from the side guard plate.

[0056] like Figure 1 and Figure 2 As shown, in this embodiment, a notch is reserved between the pedal 1 210, the pedal 2 220 and the pedal 3 250 for embedding and storing the horizontal bar 611 and the vertical bar 612. When the horizontal bar 611 and the vertical bar 612 are stored on the surface of the bottom guard plate 200, the two notches opened on the middle surface of the pedal 1 210 are used to divide the surface of the bottom guard plate 200 into 12 standing areas, and each area can accommodate one user standing.

[0057] In this embodiment, a trainee who is familiar with elevator accident prevention matters can stand on pedal three 250, and performers can stand on pedal one 210 and pedal two 220. In this way, during the drill, the trainee in the middle of the car 100 can look around to see whether the users on the side guard plates at different positions are performing standard accident prevention actions.

[0058] like Figure 5 and Figure 6 As shown, in this embodiment, a connecting tube 231 is fixedly connected between the lifting airbag 1 230 and the supporting airbag 1 340 to facilitate the gas inside the lifting airbag 1 230 to be transported into the supporting airbag 1 340, and a connecting tube 241 is fixedly connected between the lifting airbag 240 and the supporting airbag 2 440 to facilitate the gas inside the lifting airbag 240 to be transported into the supporting airbag 2 440.

[0059] Embodiment 2, on the basis of embodiment 1, in order to separate the training personnel at pedal three 250 in the middle of car 100 from the training users at pedal one 210 and pedal two 220, the training personnel in the middle of car 100 can fully check whether the training personnel are in compliance with safety protection.

[0060] like Figure 6 and Figure 8 As shown, in this embodiment, the interval dividing frame 600 includes a supporting frame 610, and the supporting frame 610 includes a cross bar 611 slidably connected to the side guard plate 300, and longitudinal bars 612 are fixed at both ends of the cross bar 611, and a plurality of support bars 620 are fixed at the bottom of the longitudinal bar 612. The internal rotation of the side guard plate 300 is connected with a screw 630 for driving the cross bar 611 to move up and down.

[0061] In this embodiment, when the car 100 accidentally falls, the screw 630 can be rotated to drive the support frame 610 and the support rod 620 to move from the surface of the bottom guard plate 200 to the outside of the user's body. The longitudinal rod 612 and the horizontal rod 611 can separate users at different pedal positions inside the car 100, providing support for the users while preventing the users from squeezing each other.

[0062] like Figure 8 and Fig. 9 As shown, in this embodiment, the support rod 620 includes a plurality of connecting blocks 621 rotatably connected to each other, and the connecting block 621 at the top end of the support rod 620 is fixedly connected to the longitudinal rod 612 .

[0063] In this embodiment, the multiple rotatably connected connecting blocks 621 will expand vertically when the longitudinal rod 612 moves upward to provide the user with horizontal support. After the drill is completed, when the longitudinal rod 612 moves downward, the multiple rotatably connected connecting blocks 621 can be shortened in length by longitudinal rotation and stored in the storage box 270. Two rectangular through holes 260 are formed on the top surface of the bottom guard plate 200, and the rectangular through holes 260 facilitate the connection blocks 621 to pass through and enter the storage box 270.

[0064] like Figure 4-5 and Figure 8-9 As shown, in this embodiment, two motors 360 for driving the screw 630 to rotate are fixed to the bottom of the side guard plate 300, and two storage boxes 270 for storing the connecting blocks 621 are fixed to the bottom of the bottom guard plate 200.

[0065] In this embodiment, when it is necessary to move the interval partition frame 600 upward as a whole, the motor 360 drives the screw 630 to rotate, and the cross bar 611 screwed together with the screw 630 will drive the entire interval partition frame 600 upward through the longitudinal bar 612. Conversely, when the motor 360 drives the screw 630 to rotate in the opposite direction, the entire interval partition frame 600 can be moved downward. The storage box 270 is connected and arranged below the rectangular through hole 260 to receive the multiple connection blocks 621 that have fallen.

[0066] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
