Description

Technical Field

[0001] The utility model relates to the technical field of elevator door machines, and more specifically, to a novel elevator door opener. Background Art

[0002] The elevator door opener, also called the elevator door machine, is a mechanism responsible for opening and closing the elevator hall car door. When it receives the elevator door opening and closing signals, the elevator door machine controls the door opening motor through its own control system, converting the torque generated by the motor into a force in a specific direction to close or open the door.

[0003] The utility model patent with publication number CN211687880U discloses an elevator door opening mechanism. The door machines of traditional car-type elevators are all single-door single-opening or double-door double-opening. Since the side-opening method has the advantages of reducing the occupied shaft area and increasing the width of the car door body, the traditional side-opening door structure adopts a double-track mechanism with a complex structure. Due to the use of a double guide rail structure, the rear end of the door panel is increased by using a guide rail with a conventional grid width; and the reduction of the guide rail width reduces the bearing capacity of the guide rail, thereby reducing the safety factor of the elevator operation. Through the cooperation of multiple structures, the two sets of door openings are not easily damaged by the vibration caused by the daily operation of the elevator. The structure effectively reduces the width of the car door, reduces the load on the guide rail, and improves the overall safety and stability of the equipment. At the same time, the structure operates stably and has good shock absorption performance.

[0004] During use, the elevator door machine structure moves by sliding the slider on the slide rod at the rear side of the car door hanging plate. The slider has a large sliding contact area on the slide rod and the friction is also large. Long-term use can easily cause wear between the slider and the slide rod. At the same time, the friction of the slider sliding on the slide rod causes a lot of noise when the door is opened and closed. Utility Model Content

[0013] It can be seen that in the above technical solution, multiple connecting springs are used to ensure that the penetration cotton plate always presses against the guide rail, ensuring that the lubricating oil can seep out.

[0014] Preferably, the top of the mobile lubricating oil box is connected to a telescopic hose, the top of the telescopic hose passes through the mobile lubricating oil box and the mobile plate in sequence, the top of the telescopic hose is connected to a lubricating oil inlet pipe, the top of the lubricating oil inlet pipe passes through the fixed box and extends to the top of the fixed box.

[0015] It can be seen that in the above technical solution, the lubricating oil can be replenished through the lubricating oil inlet pipe, so that the lubricating oil enters the interior of the mobile lubricating oil box through the telescopic hose.

[0016] Preferably, the fixed shaft is rotationally connected to the rotating roller, and the rotating roller and the fixing wheel set are both slidingly connected to the guide rail.

[0017] It can be seen that in the above technical solution, it is convenient for the rotating roller and the fixing wheel set to roll on the guide rail.

[0018] Preferably, a sound insulation layer is adhered to one side of the elevator door guide rail frame, and ventilation and heat dissipation openings are provided on the sound insulation layer and the top surface of the elevator door guide rail frame.

[0019] It can be seen that in the above technical solution, sound insulation is further performed through the sound insulation layer, and the heat dissipation effect is improved through the breathable heat dissipation vents.

[0020] Technical effects and advantages of the utility model:

[0021] 1.

At the same time, during the movement of the right car door hanging plate and the left car door hanging plate, the permeable cotton plate is pressed against the surface of the guide rail by connecting the spring rebound force, so that the permeable cotton plate is squeezed, so that the lubricating oil in the permeable cotton plate is squeezed onto the guide rail during the movement, which greatly improves the lubrication effect and further reduces the wear of internal parts when opening the door. At the same time, the continuous supply of lubricating oil can produce the effect of reducing friction and noise, and the use effect is better. At the same time, wear is reduced and the service life of the door machine is increased;

[0022] 2. By bonding a sound insulation layer to the outside of the elevator door guide frame, the sound insulation effect of the elevator door opener is further improved through the sound insulation layer, reducing the noise generated by the elevator door opener during use and improving the user experience. At the same time, the elevator door opener will inevitably generate heat due to friction during use, which is convenient for heat dissipation through the ventilation and heat dissipation ports.

[0030] The sliding mechanism includes a guide rail 4, which is welded to the front surface of the elevator door guide frame 1. A fixed shaft 5 is fixedly connected to one side of the right car door hanging plate 2 and the left car door hanging plate 3. A rotating roller 6 is installed on the outside of the fixed shaft 5. A fixing wheel group 7 is installed on one side of the right car door hanging plate 2 and the left car door hanging plate 3 near the bottom of the rotating roller 6. The number of the rotating rollers 6 is set to two, and a lubrication mechanism is provided between the two rotating rollers 6.

[0031] As attached Figure 2 , 4 As shown, the lubrication mechanism includes two fixed boxes 8, which are respectively fixed on the front sides of the right car door hanging plate 2 and the left car door hanging plate 3. A through slide groove 15 is opened on the bottom surface of the fixed box 8, and a mobile lubricating oil box 9 is slidably connected inside the through slide groove 15, so that the mobile lubricating oil box 9 can move in the vertical direction. A permeable cotton plate 10 is fixed inside the mobile lubricating oil box 9. The bottom of the permeable cotton plate 10 penetrates the mobile lubricating oil box 9 and extends to the bottom of the mobile lubricating oil box 9. A mobile plate 11 is fixed on the top of the mobile lubricating oil box 9, and the mobile plate 11 is slidably connected to the inner wall of the fixed box 8. A plurality of connecting springs 12 are fixed on the top of the mobile plate 11, and the tops of the plurality of connecting springs 12 are fixedly connected to the top of the inner wall of the fixed box 8, so that the rebound force of the connecting spring 12 makes the mobile lubricating oil box 9 move downward inside the through slide groove 15, so that the permeable cotton plate 10 presses against the guide rail 4, and the surface lubricating oil seeps out.

[0032] As attached Figure 2 , 4 As shown, a telescopic hose 13 is connected to the top of the mobile lubricating oil box 9, and the top of the telescopic hose 13 passes through the mobile lubricating oil box 9 and the mobile plate 11 in sequence. A lubricating oil inlet pipe 14 is connected to the top of the telescopic hose 13, and the top of the lubricating oil inlet pipe 14 passes through the fixed box 8 and extends to the top of the fixed box 8, so as to facilitate the addition and replenishment of the lubricating oil, so that the lubricating oil can enter the mobile lubricating oil box 9 and then enter the permeable cotton plate 10.

[0033] As attached Figure 2-4 As shown, the fixed shaft 5 is rotatably connected to the rotating roller 6, and the rotating roller 6 and the fixing wheel group 7 are both slidably connected to the guide rail 4, which facilitates the rolling of the rotating roller 6 and the fixing wheel group 7, thereby facilitating the movement of the right car door hanging plate 2 and the left car door hanging plate 3.

[0034] As attached Figure 1 , 3 As shown, a sound insulation layer 16 is adhered to one side of the elevator door guide frame 1 to improve the sound insulation effect, and ventilation and heat dissipation holes 17 are provided on the top surface of the sound insulation layer 16 and the elevator door guide frame 1 to ensure heat dissipation.

[0035] Working principle of the utility model: During use, the utility model installs rotating rollers 6 and fixing wheel groups 7 on one side of the right car door hanging plate 2 and the left car door hanging plate 3, and replaces the sliding mode of the slider on the slide rod by rolling the rotating rollers 6 and the fixing wheel groups 7 on the guide rail 4, thereby reducing the friction force. The friction between the rolling mode of the rotating rollers 6 and the fixing wheel groups 7 and the guide rail 4 is smaller, thereby reducing the wear degree of the guide rail 4 during operation. At the same time, the movable plate 11 and the movable lubricating oil box 9 are squeezed downward by the rebound force of the connecting spring 12, so that the infiltration cotton plate 10 is squeezed onto the surface of the guide rail 4, and the lubricating oil inside the movable lubricating oil box 9 penetrates into the infiltration cotton plate 10, and is squeezed between the infiltration cotton plate 10 and the guide rail 4, so that when the right car door hanging plate 2 and the left car door hanging plate 3 move, the lubricating oil is continuously squeezed and infiltrated into the outside of the guide rail 4 through the infiltration cotton plate 10, thereby improving the lubrication effect between the rotating roller 6 and the guide rail 4.

[0036] Finally: The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
