Description

Technical Field

[0001] The invention belongs to the technical field of lifting platforms, and in particular relates to a lifting platform which is convenient for mobile use. Background Art

[0002] With the rapid development of my country's subway lines, its operating scale, speed, mileage, etc. have increased rapidly. At the same time, the train maintenance work has also increased. In order to meet the above requirements, the relevant technology uses subway lifting platforms as special equipment for train installation, maintenance, daily inspection and maintenance. In the actual operation process, the lifting platform not only needs to have the lifting function, but also often requires mobile operation. During its transfer, the stability of objects or personnel on the top of the lifting platform is crucial. High-altitude workers perform high-altitude operations in a limited space. The space for operation is narrow and they need to maintain high attention at all times. If they are not careful, if they fall from a high altitude accidentally, it will cause great harm to the human body.

[0003] Chinese patent CN217535381U announces a vehicle-mounted lifting platform that is easy to move. In order to solve the problem that the bottom of the existing vehicle-mounted lifting platform needs to be disassembled and installed when it is placed, fixed and moved, which makes it cumbersome to use and not conducive to user movement, a bottom moving layer is arranged at the bottom of the vehicle-mounted lifting platform body, an installation box is arranged above the bottom moving layer, an electric lifting mechanism is arranged inside the bottom moving layer, a lifting rod is arranged at the output end of the electric lifting mechanism, a moving mechanism is arranged at the lower end of the lifting rod, the electric lifting mechanism is connected to the moving mechanism through the lifting rod, a storage groove is arranged outside the moving mechanism, a moving wheel is arranged inside the moving mechanism, a damping shock-absorbing spring is arranged at the upper end of the moving wheel, and hydraulic support mechanisms are arranged on both sides of the installation box.

[0004] The above-mentioned prior art proposes a lifting platform that is easy to move and use. Although a protective frame is set to provide basic protection for personnel, in order to facilitate personnel to work on the top of the lifting platform or to facilitate the transportation of objects on the top of it, the height of the protective frame is often only to the waist of the personnel. Due to the inconvenience of working at heights, in some cases, high-altitude workers often need to pass most of their bodies over the outside of the protective frame. If an accident occurs during operation due to some operational errors, such as not wearing a safety belt, there is a tendency for the person to fall from the outside of the protective frame to the ground. If the person falls directly to the ground, it will cause great damage to the person, or even life-threatening. When the person falls onto the surface of the object that is supported by the person, the person will roll due to the impact force. If the person rolls to the edge of the supported object, it will cause greater risks.

[0005] The use scenarios of lifting platforms in train maintenance are relatively complex, and higher requirements are placed on the safety of personnel. Therefore, we have proposed a lifting platform that is easy to move and use in order to solve the above-mentioned problems. Summary of the invention

[0035] In order to solve the problem that if there is no object at the edge of the object that is carried by the personnel, it will also cause harm to the personnel, such as Figure 4 - Fig.12As shown: the first long frame 504 inner wall is sealed and slidably connected with the first piston plate 505, the inner wall of the first long frame 504 is fixedly connected with multiple first springs 507, one end of the first spring 507 is fixedly connected to the adjacent side wall of the first piston plate 505, the top of the first piston plate 505 is fixedly connected with the first guard plate 506, the bottom of the first transfer box 517 is fixedly connected to the side wall of the first long frame 504 through the first stamping tube 519, the side wall of the first long frame 504 is fixedly connected with the first balance tube 522, and then the inner wall of the first long frame 504 can be ventilated through the first stamping tube 519, and due to the sealing condition of the first piston plate 505, in order to maintain the air pressure balance inside the first long frame 504, the gas inside the first long frame 504 will push the first piston plate 505 to move, and then the first guard plate 506 will move, and the first guard plate 506 can block the falling objects and personnel to prevent the objects or personnel from rolling after falling and falling directly through the edge of the first air cushion 503.

[0036] The second long frame 604 is sealingly and slidingly connected to the inner wall of the second long frame 604, and the second guard plate 606 is fixedly connected to the top of the second piston plate 605. A plurality of third springs 607 are fixedly connected to the inner wall of the second long frame 604, and one end of the third spring 607 is fixedly connected to the adjacent side wall of the second piston plate 605. When the gas inside the second long frame 604 is deflated, the third spring 607 quickly drives the second guard plate 606 to contract through the second piston plate 605 to reduce the time required for the entire device to contract and improve work efficiency. The bottom of the second transfer box 614 is fixedly connected to the side wall of the second long frame 604 through the second stamping tube 616, and the side wall of the second long frame 604 is fixedly connected to the second balance tube 618.

[0037] The side walls of the first exhaust pipe 521, the first balance pipe 522, the second exhaust pipe 617 and the second balance pipe 618 are all fixedly installed with a third solenoid valve, and the side walls of the first pressure relief pipe 523 and the second pressure relief pipe 623 are all fixedly installed with a sixth solenoid valve, so that the deflation process of the internal gas of the first air cushion 503, the second air cushion 603, the first long frame 504 and the second long frame 604 can be controlled by the third solenoid valve, and the deflation process of the first pneumatic cylinder 510 and the second pneumatic cylinder 619 can be controlled by the sixth solenoid valve, and the first solenoid valve 514, the second solenoid valve 520, the third solenoid valve, the fourth solenoid valve 612, the fifth solenoid valve 613 and the sixth solenoid valve are all electrically connected to the external controller, so that these structures can be controlled by the regulator 8.

[0038] When the second solenoid valve 520 and the fifth solenoid valve 613 are started, the first long frame 504 and the second long frame 604 can be inflated through the first stamping tube 519 and the second stamping tube 616, and then the first long frame 504 and the second long frame 604 will push the first piston plate 505 and the second piston plate 605 to move in order to maintain the air pressure balance, thereby driving the first guard plate 506 and the second guard plate 606 to move, thereby protecting the side walls of the first air cushion 503 and the second air cushion 603 to prevent people or objects from falling directly from the edge of the first air cushion 503 and the second air cushion 603.

[0039] When the entire first protection component 5 and the second protection component 6 need to be retracted into the working component 3, first open the third solenoid valve to deflate the gas inside the first air cushion 503, the second air cushion 603, the first long frame 504 and the second long frame 604. When the first air cushion 503, the first guard plate 506, the second air cushion 603 and the second guard plate 606 shrink back to their initial positions, start the sixth solenoid valve to deflate the gas inside the first pneumatic cylinder 510 and the second pneumatic cylinder 619. During this process, the first spring 507, the second spring 515, the third spring 607 and the fourth spring 621 can quickly drive the first piston plate 505, the second piston plate 605, the first movable column 511 and the second movable column 620 to move, thereby facilitating the rapid resetting of the entire first protection component 5 and the second protection component 6 for subsequent continued use.
