[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 6 As shown, the utility model provides a device for realizing forward and reverse direction movement through a synchronous wheel, comprising an arc door machine mounting plate 1, a circular door machine upper sill plate 2 is fixedly installed at the bottom of the circular door machine mounting plate 1, a door machine assembly 3 is fixedly installed in the middle of the top of the circular door machine mounting plate 1, door machine triangular tensioning mechanisms 4 are symmetrically installed at both ends of the top of the circular door machine mounting plate 1, a door machine tensioning wheel 5 is installed at the top of the circular door machine mounting plate 1 between the door machine assembly 3 and the door machine triangular tensioning mechanism 4, a belt 6 is wound on the surface of the door machine triangular tensioning mechanism 4, which contacts the surface of the door machine assembly 3 and the door machine tensioning wheel 5 and forms tension, a door machine door knife mechanism 7 is installed on the surface of the belt 6, and a hanger upper sill plate 8 is slidably connected to the outer side of the door machine door knife mechanism 7 through a pulley and a slide rail.

[0023] The above scheme is adopted: the belt 6 is driven to move by starting the door machine assembly 3, and through the unique design of the door machine assembly 3, the belts 6 arranged at both ends of the door machine assembly 3 can move synchronously in the same direction or in the opposite direction, and the movement of the belt 6 drives the door knife mechanism 7 of the door machine to move, so that the door knife mechanism 7 drives the bottom arc car door 13 to open or close, so as to realize the opening and closing of the arc-shaped elevator door, and the device adopts the movement of the belt 6 to cooperate with the upper sill plate 8 of the pendant and the arc car door sill 15 to guide the arc car door 13 to realize the opening and closing of the elevator door, and there is no gear for transmission, which effectively reduces the wear and lubrication consumption in the transmission process, so that the service life of the equipment is longer and the use is more stable.

[0024] like Figure 2 , 3As shown, a transmission wheel is arranged on the surface of the door machine assembly 3. When the door machine assembly 3 is working, two adjacent transmission wheels on its surface rotate synchronously in opposite directions, and the movement directions of the door machine triangular tensioning mechanisms 4 located on both sides of the door machine assembly 3 are also opposite. The two groups of door machine door knife mechanisms 7 move in opposite directions when working. The bottom of the door machine door knife mechanism 7 is connected to an arc car door 13, and the transmission wheels on the door machine assembly 3 are connected through a transmission belt.

[0025] The above scheme is adopted: the door machine assembly 3 is provided with a motor inside, and a driving wheel is installed on the output shaft of the motor. The driving wheel is located alone on one side, and the rest are transmission wheels. The transmission belt is wound between the driving wheel and the transmission wheel. The winding method is as follows: Figure 3 As shown in , this connection mode causes the two driving wheels connected to the belt 6 to rotate in opposite directions, thereby causing the two belts 6 to move in opposite directions, and then causing the door machine door knife mechanism 7 fixed on the belt 6 to move in opposite directions, thereby achieving the purpose of synchronous opening and closing of the two arc car doors 13.

[0026] like Figure 2 , 4 As shown, the connecting lines between the door machine assembly 3, the door machine triangular tensioning mechanism 4 and the door machine tensioning wheel 5 form an obtuse triangle, the door machine tensioning wheel 5 is located at the outward end of the top of the arc door machine mounting plate 1, the belt 6 is sleeved on the door machine tensioning wheel 5 and the door machine tensioning wheel 5 squeezes the belt 6 into an outwardly expanded arc shape.

[0027] The above scheme is adopted: through the cooperation of the door machine triangular tensioning mechanism 4 and the door machine tensioning wheel 5, the belt 6 can be always kept in a taut state, and the movement of the door machine triangular tensioning mechanism 4 can ensure that the belt 6 is always in a stable state when subjected to force, thereby ensuring that when the driving wheel on the door machine assembly 3 rotates, there is sufficient friction to drive the door machine door knife mechanism 7 to move, and it will not cause excessive tension to affect the elasticity of the belt 6. At the same time, the door machine tensioning wheel 5 also makes the end of the belt 6 close to the arc door frame 11 close to an arc shape, ensuring that the door machine door knife mechanism 7 drives the movement of the arc car door 13 more stably.

[0028] like Figure 1 , 4 As shown, the door machine assembly 3 is provided with a hanging recovery joint 9 at one end facing the outer edge of the arc door machine mounting plate 1, and a hanging slide assembly 16 is provided at the bottom of the hanging slide assembly 16, and a hall door triangular lock 10 is fixedly installed at the bottom of the hanging slide assembly 16, and an arc hall door 12 is fixedly connected to one end of the bottom of the hanging slide assembly 16 away from the hall door triangular lock 10; it also includes an arc door cover 11 for limiting and supporting the arc hall door 12 and the arc car door 13, an arc hall door sill 14 for guiding the sliding of the arc hall door 12, and an arc car door sill 15 for guiding the sliding of the arc car door 13.

[0029] The above solution is adopted: the sliding of the arc hall door 12 is guided by the set hanging slide assembly 16, and the arc hall door 12 can be locked by the hall door triangular lock 10 after it moves, so as to prevent the elevator door from opening accidentally during the up and down process of the elevator.

[0030] The working principle and use process of this utility model:

[0031] When in use, start the door machine assembly 3 to drive the belt 6 to move. At this time, the belts 6 arranged at both ends of the door machine assembly 3 can move synchronously in the same direction or in the opposite direction. The movement of the belt 6 drives the door machine door knife mechanism 7 to move, so that the door machine door knife mechanism 7 drives the bottom arc car door 13 to open or close, thereby realizing the opening and closing of the arc-shaped elevator door. In addition, the device uses the movement of the belt 6 to cooperate with the upper sill plate 8 of the pendant and the arc car door sill 15 to guide the arc car door 13 to realize the opening and closing of the elevator door. There is no gear for transmission, which effectively reduces the wear and lubrication consumption in the transmission process, making the service life of the equipment longer and the use more stable.
