[0004] The aforementioned methods, which rely on the coordination between components such as construction hoists and personnel / freight conveyors, fail to effectively isolate the lifting area of ​​freight elevators. This increases the risk of people accidentally entering or being injured, reducing the safety performance of freight elevators and warrants improvement. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides an automatic safety protection door for a freight elevator, which solves the technical problem in the related / existing technology that an automatic safety protection door for a freight elevator cannot effectively isolate the lifting area of ​​the freight elevator.

[0006] According to one aspect, at least one embodiment of the present invention provides an automatic safety gate for a freight elevator, including a support rod, a freight elevator plate slidably connected to the side of the support rod, an automatic safety gate assembly provided on the side of the support rod, the automatic safety gate assembly including a freight elevator guardrail, the bottom of the freight elevator guardrail being fixedly connected to the top of the freight elevator plate, a triangular rod being fixedly connected to the top of the freight elevator guardrail, a crossbar being fixedly connected to the side of the triangular rod, a crossbar being fixedly connected to the side of the support rod, and a lift being fixedly connected to the bottom of the crossbar. A connecting strap is provided at the bottom. The end of the connecting strap away from the elevator is fixedly connected to the top of the crossbar. A first guardrail is fixedly connected to the top of the triangular rod. A vertical rod is fixedly connected to the side of the support rod. A second guardrail is slidably connected to the inner wall of the vertical rod. A slot is provided at the top of the second guardrail. A mounting plate is fixedly connected to the side of the support rod. A pulley is provided on the inner wall of the mounting plate. A connecting rope is provided on the outer wall of the pulley. One end of the connecting rope is fixedly connected to the inner wall of the slot. The end of the connecting rope away from the slot is fixedly connected to the top of the freight elevator platform.

[0007] For example, in at least one embodiment of the present invention, an automatic safety guard door for a freight elevator is provided, which further includes: the guard rod is located on the side of the support rod, and two freight elevator guardrails are provided, which are symmetrical to each other along the vertical central axis of the freight elevator plate. The provision of two freight elevator guardrails is beneficial to protect the transported goods and prevent the goods from falling accidentally.

[0008] Two triangular rods are provided and are symmetrical to each other along the vertical central axis of the freight elevator platform. The elevator is located at the top of the freight elevator platform. The design of the elevator facilitates the automatic driving of the freight elevator platform to move up and down.

[0009] The support rods are arranged in pairs, symmetrically arranged along the vertical central axis of the elevator platform. The support rods are rectangular in shape and have multiple support rods, which helps to provide stable support for the elevator platform.

[0010] The second guardrail is located on the side of the freight elevator railing. There are two vertical bars, which are symmetrical to each other along the vertical center axis of the horizontal bar. The design of the second guardrail is to block the freight elevator platform after it rises, preventing people or goods from getting close.

[0011] The top of the freight elevator platform is equipped with a locking device. There are two locking devices, which are symmetrical about each other along the vertical central axis of the freight elevator platform. The design of the locking device is conducive to forcibly decelerating the freight elevator platform when its movement is out of control, thereby protecting the freight elevator platform.

[0012] According to another aspect, at least one embodiment of this utility model also provides an automatic safety protection door for a freight elevator, comprising: an intermittent automatic lubrication assembly provided at the top of the crossbar, the intermittent automatic lubrication assembly including a short rod, one end of the short rod being fixedly connected to the top of the crossbar, a motor being fixedly connected to the side of the short rod, a half gear being fixedly connected to the output shaft of the motor, a rack being slidably connected to the top of the crossbar, a pressing plate being fixedly connected to one end of the rack, an airbag being fixedly connected to the top of the crossbar, and an oil outlet pipe penetrating the side of the airbag, using the flowing lubricating oil to lubricate the connecting belt, preventing the connecting belt from jamming when driving the freight elevator platform to move up and down, which helps to ensure the stable up and down movement of the freight elevator platform.

[0013] For example, in at least one embodiment of the present invention, an automatic safety protection door for a freight elevator is provided, which further includes: the airbag is located on the displacement trajectory of the extrusion plate, the half gear and the rack mesh with each other, and the end of the oil outlet pipe away from the airbag is located on the side of the connecting belt. This design is beneficial to drive the rack to move when the half gear rotates.

[0014] The top of the airbag has a replenishment tube, and a limiting rod is fixedly connected to the side of the rack. The end of the limiting rod away from the rack is slidably connected to the side of the crossbar. The design of the limiting rod helps to restrict the position of the rack and prevent the rack's movement trajectory from deviating.

[0015] A spring is fixedly connected to one end of the rack, and the end of the spring away from the rack is fixedly connected to the side of the crossbar. The design of the spring is conducive to the rack automatically returning to its original position when it is not being driven.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. In this utility model, through the cooperation between the elevator, connecting belt, guardrail one, and other components inside the automatic safety protection door assembly, the automatic safety protection door can effectively prevent personnel or objects from contacting the lifting components or dangerous areas during the operation of the freight elevator. When the freight elevator platform, guardrail, etc., move up and down, the linkage design of guardrail one and guardrail two ensures that the lifting area of ​​the freight elevator is effectively isolated, reducing the risk of personnel accidentally entering or being pinched. Guardrail one and guardrail two can automatically rise and fall and provide timely protection. This automated safety protection system does not require manual intervention and can intelligently adjust the protection measures according to the movement state of the freight elevator, thereby enhancing the safety performance of the freight elevator.

[0018] 2. In this utility model, through the cooperation between the motor, half gear, airbag and other components inside the intermittent automatic lubrication component, lubricating oil is provided to the connecting belt periodically and intermittently. This effectively reduces the friction between the components during the lifting of the freight elevator, prevents the wear of parts due to excessive friction, and thus extends the service life of the system. It also ensures that the supply of lubricating oil is neither too much nor too little in different working cycles, maintaining the stability and reliability of the system.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5As shown, an automatic safety gate for a freight elevator according to an embodiment of the present invention is provided, comprising: a support rod 1, a freight elevator plate 2 slidably connected to the side of the support rod 1, an automatic safety gate assembly 3 provided on the side of the support rod 1, the automatic safety gate assembly 3 including a freight elevator guardrail 31, the bottom of the freight elevator guardrail 31 being fixedly connected to the top of the freight elevator plate 2, a triangular rod 32 being fixedly connected to the top of the freight elevator guardrail 31, a crossbar 33 being fixedly connected to the side of the triangular rod 32, a crossbar 34 being fixedly connected to the side of the support rod 1, a lifting mechanism 35 being fixedly connected to the bottom of the crossbar 34, and a connecting strap 36 being provided at the bottom of the lifting mechanism 35. The end of the connecting strap 36 away from the elevator 35 is fixedly connected to the top of the crossbar 33. The top of the triangular rod 32 is fixedly connected to the first guard rod 37. The side of the support rod 1 is fixedly connected to the vertical rod 312. The inner wall of the vertical rod 312 is slidably connected to the second guard rod 313. The top of the second guard rod 313 is provided with a slot 314. The side of the support rod 1 is fixedly connected to the mounting plate 38. The inner wall of the mounting plate 38 is provided with a pulley 39. The outer wall of the pulley 39 is provided with a connecting rope 310. One end of the connecting rope 310 is fixedly connected to the inner wall of the slot 314. The end of the connecting rope 310 away from the slot 314 is fixedly connected to the top of the freight elevator plate 2.

[0033] In some examples, guardrail 37 is located on the side of support rod 1, and there are two freight elevator guardrails 31, which are symmetrical to each other along the vertical central axis of freight elevator plate 2. The presence of two freight elevator guardrails 31 is beneficial for protecting the transported goods and preventing them from falling accidentally.

[0034] Two triangular rods 32 are provided and are symmetrical to each other along the vertical central axis of the freight elevator plate 2. The elevator 35 is located at the top of the freight elevator plate 2. The design of the elevator 35 is conducive to automatically driving the freight elevator plate 2 to move up and down.

[0035] Several support rods 1 are provided, arranged in pairs and symmetrically along the vertical central axis of the freight elevator platform 2. The support rods 1 are rectangular in shape, and the presence of several support rods 1 is beneficial for providing stable support to the freight elevator platform 2.

[0036] The second guardrail 313 is located on the side of the freight elevator guardrail 31. There are two vertical bars 312, which are symmetrical to each other along the vertical central axis of the horizontal bar 33. The design of the second guardrail 313 is conducive to blocking the freight elevator plate 2 after it rises, preventing people or goods from getting close.

[0037] The top of the freight elevator platform 2 is equipped with a locking device 311. There are two locking devices 311, which are symmetrical about each other along the vertical central axis of the freight elevator platform 2. The design of the locking device 311 is conducive to forcibly decelerating the freight elevator platform 2 when its movement is out of control, thereby protecting the freight elevator platform 2.

[0038] For example, such as Figure 1-5 As shown in this application, the lifting platform 35 drives the connecting belt 36 to move up and down. The up-and-down movement of the connecting belt 36 causes the crossbar 33 to move up and down, which in turn causes the triangular rod 32, the freight elevator guardrail 31, and the freight elevator platform 2 to move up and down, enabling the freight elevator to automatically lift and lower goods. When the triangular rod 32, the freight elevator guardrail 31, and the freight elevator platform 2 move downwards, they cause the guardrail 37 to move upwards. The guardrail 37 protects the triangular rod 32, the freight elevator guardrail 31, and the freight elevator platform 2 at the upward lifting point, preventing people or other objects from moving there and blocking them from approaching. When the triangular rod 32, the freight elevator guardrail 31, and the freight elevator platform 2 move upwards, they drive the pulleys... Rotation of 39 causes the connecting rope 310 to rotate, moving the second guardrail 313 downwards along the vertical rod 312. The second guardrail 313 then horizontally blocks the side of the freight elevator railing 31, protecting the freight elevator platform 2. The automatic safety guardrail effectively prevents personnel or objects from contacting the lifting components or dangerous areas during the operation of the freight elevator. When the freight elevator platform 2 and railing move up and down, the linkage design of the first guardrail 37 and the second guardrail 313 ensures that the lifting area of ​​the freight elevator is effectively isolated, reducing the risk of personnel accidentally entering or being pinched. The first guardrail 37 and the second guardrail 313 can automatically rise and fall and provide timely protection. This automated safety protection system requires no manual intervention and can intelligently adjust the protection measures according to the movement status of the freight elevator, enhancing the safety performance of the freight elevator.

[0039] like Figures 1-5 As shown, this invention illustrates an automatic safety door for a freight elevator in another embodiment, comprising: an intermittent automatic lubrication assembly 4 at the top of a crossbar 34, the intermittent automatic lubrication assembly 4 including a short rod 41, one end of which is fixedly connected to the top of the crossbar 34, a motor 42 fixedly connected to the side of the short rod 41, a half gear 43 fixedly connected to the output shaft of the motor 42, a rack 44 slidably connected to the top of the crossbar 34, a pressing plate 45 fixedly connected to one end of the rack 44, and an airbag 46 fixedly connected to the top of the crossbar 34, with an oil outlet pipe 47 penetrating the side of the airbag 46 to lubricate the connecting belt 36 with the flowing lubricating oil, preventing the connecting belt 36 from jamming when driving the freight elevator platform 2 to move up and down, thus ensuring the stable up and down movement of the freight elevator platform 2.

[0040] In some examples, the airbag 46 is located on the displacement trajectory of the extrusion plate 45, the half gear 43 and the rack 44 mesh with each other, and the end of the oil outlet pipe 47 away from the airbag 46 is located on the side of the connecting belt 36. This design is beneficial to drive the rack 44 to move when the half gear 43 rotates.

[0041] The top of the airbag 46 has a supplement tube 48 through it. A limiting rod 410 is fixedly connected to the side of the rack 44. The end of the limiting rod 410 away from the rack 44 is slidably connected to the side of the crossbar 34. The design of the limiting rod 410 helps to limit the position of the rack 44 and prevent the movement trajectory of the rack 44 from deviating.

[0042] A spring 49 is fixedly connected to one end of the rack 44. The end of the spring 49 away from the rack 44 is fixedly connected to the side of the crossbar 34. The design of the spring 49 is conducive to the rack 44 automatically resetting when it is not driven.

[0043] For example, such as Figure 1-5 As shown, when motor 42 is started, its rotation drives half gear 43 to rotate, which in turn drives some of the teeth to rotate. These teeth mesh with rack 44. When some teeth rotate onto rack 44, they move rack 44 closer to airbag 46, causing rack 44 to slide on top of crossbar 34. As rack 44 slides, it pulls spring 49. Airbag 46 is located on the movement trajectory of squeezing plate 45. Airbag 46 contains lubricating oil. When airbag 46 is squeezed, the lubricating oil flows out through oil outlet pipe 47. One end of oil outlet pipe 47 is located on the side of connecting belt 36. The squeezed lubricating oil flows onto connecting belt 36, lubricating the connecting belt 36 that drives the freight elevator platform 2 to rise and fall. To prevent jamming, as the half gear 43 continues to rotate, when some teeth do not rotate to drive the rack 44, the rack 44 will not move. The rack 44 and the pressing plate 45 will automatically reset through the spring 49, allowing the pressing plate 45 to move intermittently and intermittently press the airbag 46. This causes the oil outlet pipe 47 to intermittently output oil to lubricate the connecting belt 36. By periodically and intermittently providing lubricating oil to the connecting belt 36, the friction between various components during the lifting of the freight elevator can be effectively reduced, preventing wear of parts due to excessive friction and thus extending the service life of the system. Through the design of the spring 49 and the rack 44, the system can achieve intermittent lubrication, ensuring that the supply of lubricating oil is neither too much nor too little in different working cycles, maintaining the stability and reliability of the system.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
