AI Technical Summary
When the existing screw-type opening and closing machine is synchronized by the power transmission of bevel gears in multiple positions, the opening and closing rods are not stable enough and lacks self-locking function, which causes the opening and closing rods to fall automatically.
The design of multiple side wheels meshing with bevel gears is adopted. The side wheel rotation is driven by the reducer motor, and the transmission sleeve and bent rod are used to transmit power to ensure stable rotation of bevel gears, and the opening and closing rods are prevented from automatically falling through the self-locking function.
Multi-position synchronous opening and closing rod lifting is realized, which enhances the stability and self-locking function of the opening and closing machine, prevents the opening and closing rod from rotating eccentrically, and ensures stability and reliability for long-term use.

[0020] refer to Figure 1 、 2 , 3 and 5, describe in detail the working example of the gate hoist:
[0021] A screw-type gate hoist comprises a mounting frame 11, wherein a plurality of mounting holes are provided on the edge of the mounting frame 11. The mounting frame 11 is used to install the mounting frame 11 through a plurality of mounting holes for passing bolts to achieve the fixation of the mounting frame 11. The middle part of the mounting frame 11 is rotatably connected to a spiral frame 12, and the spiral frame 12 can rotate around its own axis. The opening and closing rod 21 is spirally connected in the spiral frame 12. The spiral frame 12 and the opening and closing rod 21 are driven by a spiral transmission. When the spiral frame 12 rotates around its own axis, the spiral frame 12 drives the opening and closing rod 21 to be raised and lowered when the rotation direction is limited, thereby realizing the operation of the opening and closing machine. A connecting frame 13 is fixedly connected to the outer edge of the spiral frame 12, and a bevel gear 14 is fixedly connected to the outer edge of the connecting frame 13. A plurality of side wheels 31 that mesh with the driving bevel gear 14 to rotate are rotatably connected to the mounting frame 11. When one or more of the plurality of side wheels 31 rotate, the driving bevel gear 14 rotates, and the bevel gear 14 rotates, driving the connecting frame 13 to rotate, and the connecting frame 13 drives the spiral frame 12 to rotate, thereby realizing the driving of the opening and closing rod 21, and then realizing the lifting and lowering of the opening and closing rod 21.
[0022] refer to Figure 1 and 5 , an embodiment of driving the bevel gear 14 to rotate stably is described in detail:
[0023] There are at least two side wheels 31, so that the bevel gear 14 can be supported to rotate stably through multiple side wheels 31, ensuring the stable operation of the bevel gear 14 and preventing the bevel gear 14 from eccentric operation and wear, which affects the long-term use of the gate hoist.
[0024] refer to Figure 1 and 2 , an embodiment in which multiple side wheels 31 obtain power to rotate is described in detail:
[0025] The mounting frame 11 is fixedly connected to a plurality of reduction motors I which drive the corresponding side wheels 31 to rotate through the output shafts. When the plurality of reduction motors I are started, the output shafts of the plurality of reduction motors I drive the plurality of side wheels 31 to rotate, and the plurality of side wheels 31 obtain power, thereby realizing stable operation of the gate hoist.
[0026] With reference to 1, 5, 6 and 7, embodiments in which multiple side wheels 31 obtain power are described in detail:
[0027] The end of each side wheel 31 is fixedly connected to a transmission sleeve 32, and each transmission sleeve 32 is detachably connected to a drive sleeve 33. A plurality of bent rods 34 are threadedly connected to the outer wall of each drive sleeve 33, so that the drive sleeve 33 can be manually driven to rotate by holding the plurality of bent rods 34. The rotation of one or more drive sleeves 33 drives the plurality of transmission sleeves 32 to rotate, so that the plurality of side wheels 31 can be rotated after obtaining power, thereby realizing the input of power for raising and lowering the opening and closing rod 21.
[0028] refer to Figure 6 and 7 , an embodiment of the power transmission between the side wheel 31 and the drive sleeve 33 is described in detail:
[0029] Multiple transmission keys are formed on the outer wall of each transmission sleeve 32. Each drive sleeve 33 is formed with a transmission slot that couples with its corresponding transmission sleeve 32. This coupling between the transmission keys and the transmission slots allows for power transmission, ensuring that rotation of the multiple drive sleeves 33 drives the multiple side wheels 31, thereby providing power input for raising and lowering the opening and closing lever 21.
[0030] refer to Figure 7 , detailed description of the embodiment of the stable rotation bent rod 34:
[0031] The multiple curved rods 34 provided on each of the driving sleeves 33 are evenly distributed, thereby ensuring that the multiple curved rods 34 can be manually grasped and rotated, thereby achieving stable rotation of the multiple driving sleeves 33.
[0032] refer to Figure 4 and5 , an embodiment of preventing the limiting connection frame 13 from sliding in the axial direction is described in detail:
[0033] The upper end surface of the connecting frame 13 fits with the lower end surface of the upper part of the mounting frame 11, thereby limiting the upper end of the connecting frame 13. The multiple side wheels 31 can limit the bevel gear 14 in the downward direction to ensure the axial stability of the connecting frame 13.
[0034] refer to Figure 5 , an embodiment in which the side wheel 31 drives the bevel gear 14 is described in detail:
[0035] The multiple side wheels 31 are located at the lower part of the bevel gear 14, so that the multiple side wheels 31 can limit the lower part of the bevel gear 14. At the same time, the bevel gear 14 can prevent the opening and closing rod 21 from descending under the action of the gravity of the opening and closing rod 21 and the gate installed thereon. The engagement of the multiple side wheels 31 with the bevel gear 14 has a self-locking effect, ensuring that the multiple side wheels 31 can rotate under force, thereby realizing the driving of the bevel gear 14.
