Abstract
Description
Technical Field
[0001] The utility model relates to a transformation structure, in particular to an integral frame and a truss transformation structure for an old escalator, belonging to the technical field of truss transformation. Background Art
[0002] An escalator is a fixed electric drive device consisting of a chain or rack drive mechanism, a step system, a handrail system, a guide rail system, an electrical control system and other parts. It transports people through circulating steps and is widely used in crowded places such as stations, shopping malls, and airports. When an escalator is renovated and upgraded, the ladder system, control system, drive system, handrail system, lubrication system, etc. are generally replaced and upgraded without destroying the original truss main structure. The original escalator truss is calibrated, cleaned and surface protected to minimize resource loss.
[0003] In the existing transformation process, in addition to renovating the appearance, the most core part is to detect the performance of the drive mechanism. The drive mechanism is generally composed of an electric motor and some transmission shafts or gears and other components. The transmission shafts or gears can be reused by derusting and re-lubricating without replacement. However, the motor is the core component of the escalator drive system. It is responsible for providing power to drive the entire escalator system. The quality of the motor directly affects the overall use. After a long period of use, the motor is generally removed and replaced. When removing the motor, due to the complex connection relationship between the motor and the outside, it often affects many transmission components during removal and needs to be removed together, which is more cumbersome. For this reason, we provide an integral frame and a truss modification structure for the old escalator to solve the above problems. Utility Model Content
[0004] In order to solve the above problems, the utility model provides an integral frame and a truss reconstruction structure for an old escalator to solve the above problems. The specific technical solutions are as follows:
[0005] An integral frame and a truss reconstruction structure for an old escalator include a frame body, a fixed shell installed at one end of the frame body, a bottom plate installed on the lower surface of the fixed shell, a disassembly plate detachably connected to the upper surface of the fixed shell, a movable plate provided on the upper surface of the bottom plate, an electric motor installed on the movable plate, an output end of the electric motor connected to a connecting sleeve, an inner wall of the connecting sleeve slidably connected to a transmission rod, a locking mechanism provided inside the transmission rod, an outer surface of the transmission rod connected to a transmission assembly, an inner wall of the fixed shell slidably connected to a lifting plate, and a lifting mechanism provided outside the lifting plate.
[0006] Preferably, an inclined plate is provided on one side of the lifting plate, the lower surface of the inclined plate is fixedly connected to the bottom plate, and the bottom movable box of the movable plate is inlaid with a plurality of balls, the outer surfaces of the balls are in contact with the bottom plate.
[0007] Preferably, the lower surface of the disassembly plate is fixedly connected to a limit plate, and the upper surface of the base plate is fixedly connected to a fixing plate.
[0008] Preferably, the end of the transmission rod is fixedly connected to a limit block, and the outer surface of the limit block is rotatably connected to the fixed shell.
[0009] Preferably, the locking mechanism includes a sliding block, the outer surface of the sliding block is slidably connected to the inner wall of the transmission rod, the outer surface of the sliding block is connected to a clamping block, the outer surface of the clamping block is slidably connected to the connecting sleeve, there are two sliding blocks and two clamping blocks, and a spring is installed between the two sliding blocks.
[0010] Preferably, the lifting mechanism includes a connecting plate, one side of the connecting plate is fixedly connected to the lifting plate, the side of the lifting plate away from the connecting plate is fixedly connected to a limiting rod, and the connecting plate and the limiting rod are both slidably connected to the fixed shell.
[0011] Preferably, a threaded rod is threadedly connected to the inner wall of the connecting plate, and the lower end of the threaded rod is rotatably connected to the bottom plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The integral frame and the truss reconstruction structure of the old escalator are provided with components such as a connecting sleeve and a movable plate. The disassembly plate is first opened, so that the movable plate is no longer limited. The connecting sleeve is separated from the transmission rod by a locking mechanism, thereby separating the motor from the transmission rod, pushing the movable plate to slide onto the lifting plate, and the lifting plate is driven upward by the lifting mechanism, so that the motor moves to the top of the fixed shell. The motor can then be inspected, repaired or disassembled without disassembling other transmission components, thereby achieving the effect of facilitating the disassembly of the motor. This solves the existing problem that when disassembling the motor, due to the complex connection relationship between the motor and the outside, many transmission components are often affected during disassembly, and they need to be disassembled together, which is more cumbersome.
[0014] 2. The integral frame and the truss reconstruction structure of the old escalator are provided with a locking mechanism and other components. When the connecting sleeve is sleeved on the outside of the transmission rod, the block is squeezed into the inside of the transmission rod. When the connecting sleeve starts to rotate, the card slot moves to the block, thereby achieving an automatic locking effect, so that the transmission rod rotates synchronously with the connecting sleeve, achieving the effect of facilitating connection. When installed and used, the movable plate and the motor are clamped in the middle by the limit plate and the fixed plate to increase their stability and make the operation more stable. When disassembling, the limit plate can be removed along with the disassembly plate to leave space for the movable plate to move. BRIEF DESCRIPTION OF THE DRAWINGS

The outer surface of the transmission rod 8 is connected to a transmission assembly 10, and the inner wall of the fixed shell 2 is slidably connected to a lifting plate 11, and a lifting mechanism 12 is provided on the outside of the lifting plate 11. Other transmission parts are also installed inside the frame body 1 Parts, a railing is also installed on the outside, which has been omitted in the figure. This is a prior art and will not be described in detail here. The disassembly plate 4 is fixed to the fixed shell 2 by bolts or the like. When necessary, it can be removed from the fixed shell 2. The movable plate 5 serves as a component supporting the motor 6. The motor 6 can drive the transmission rod 8 to rotate through the connecting sleeve 7. The transmission rod 8 drives the power shaft of the elevator to rotate through the transmission assembly 10 to drive the elevator to run. The transmission assembly 10 is composed of components such as a transmission belt. Different installation methods can be adjusted according to actual conditions. The output end of the motor 6 is equipped with auxiliary components such as a brake to ensure smooth operation of the escalator.
[0024] An inclined plate 13 is provided on one side of the lifting plate 11, and the lower surface of the inclined plate 13 is fixedly connected to the bottom plate 3. The bottom movable box of the movable plate 5 is inlaid with multiple balls 17, and the outer surface of the balls 17 is in contact with the bottom plate 3. The balls 17 are used to reduce the friction between the movable plate 5 and the bottom plate 3 so that the movable plate 5 can slide on the bottom plate 3. The inclined plate 13 is provided so that the movable plate 5 can slide onto the lifting plate 11 to prevent it from getting stuck.
[0025] The lower surface of the disassembly plate 4 is fixedly connected to a limit plate 14, and the upper surface of the base plate 3 is fixedly connected to a fixed plate 15. When installed and used, the movable plate 5 and the motor 6 are clamped in the middle by the limit plate 14 and the fixed plate 15 to increase their stability and make the operation more stable. When disassembling, the limit plate 14 can be removed along with the disassembly plate 4 to leave space for the movable plate 5 to move.
[0026] The end of the transmission rod 8 is fixedly connected to a limit block 16, and the outer surface of the limit block 16 is rotatably connected to the fixed shell 2.

[0029] The inner wall of the connecting plate 1201 is threadedly connected to a threaded rod 1202, and the lower end of the threaded rod 1202 is rotatably connected to the base plate 3. When disassembling, the threaded rod 1202 can be twisted to drive the connecting plate 1201 to move upward, causing the lifting plate 11 to move upward without the need for lifting, thereby achieving a labor-saving effect.
[0030] The electric motor 6 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure, and it can also be replaced by other power sources.
[0031] When the motor 6 is disassembled according to the present invention, the disassembly plate 4 is first opened, and the disassembly plate 4 drives the limiting plate 14 to be removed from the inside of the fixed shell 2, so that the movable plate 5 is no longer limited, and then the block 902 is pressed to separate the connecting sleeve 7 from the transmission rod 8, thereby separating the motor 6 from the transmission rod 8, so that the motor 6 can be taken out, and the movable plate 5 is pushed to slide onto the lifting plate 11, and the lifting plate 11 is driven to move upward by the lifting mechanism 12, so that the motor 6 moves to the top of the fixed shell 2, and then the motor 6 is inspected, repaired or disassembled without disassembling other transmission components, thereby achieving the effect of facilitating the disassembly of the motor 6.
