The meaning of "several" is one or more than one, unless otherwise specifically limited.

[0030] In the description of the utility model, it is also necessary to explain that, unless otherwise specifically specified and limited, the terms "set", "mount", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0031] Referring to Figures 1-3 The utility model embodiment provides a kind of friction power hoist, including frame 1, rotatable setting on the frame 1 lifting wheel 2 and setting on the frame 1 lifting plate 3, the lifting plate 3, frame 1 and lifting wheel 2 form the curved channel 4 capable of ascending between, the curved channel 4 includes ball inlet 41 and ball outlet 42, the height of ball outlet 42 is greater than the height of ball inlet 41.

[0032] Referring to Figures 1-3 The frame 1 includes vertical plate 11 arranged on the left and right sides of the axial direction of lifting wheel 2, the inner side of vertical plate 11 is provided with guard plate 12, the guard plate 12 is distributed along the lifting track of ball, and the guard plate 12 is nylon piece. Bowling ball will not be in direct contact with 8 frame during movement, and bowling ball is protected from injury.

[0033] Referring to Figures 1-3 The lifting plate 3 is perpendicular to the vertical plate 11, and the channel width between the lifting plate 3 and the lifting wheel 2 is less than the diameter of the spherical object.

[0034] Referring toFigures 1-3 The lifting wheel 2 includes transmission wheel A 21 and transmission wheel B 22, which are opposite to each other; transmission wheel A 21 and transmission wheel B 22 correspond to a lifting plate 3 respectively and form an S-shaped channel.

[0035] Referring to Figures 1-3 It also includes a motor 5, which drives transmission wheel A 21 and transmission wheel B 22 to rotate through a transmission mechanism 6.

[0036] Referring to Figures 1-3 The transmission mechanism 6 includes a driving wheel 61 arranged on the motor 5, a reversing wheel 62 arranged on the frame 1 and a tension wheel 63, and further includes a transmission belt 64; transmission wheel A 21, driving wheel 61 and reversing wheel 62 are arranged inside the transmission belt 64, and transmission wheel B 22 and tension wheel 63 are arranged outside the transmission belt 64.

[0037] Referring to Figures 1-3 Transmission wheel A 21 is provided with a lower polyurethane friction wheel 211 inside the frame 1, and transmission wheel B 22 is provided with an upper polyurethane friction wheel 221 inside the frame 1; the lower polyurethane friction wheel 211 and the upper polyurethane friction wheel 221 are both V-shaped elastic wheels; transmission wheel A 21 and transmission wheel B 22 are made of cast iron outside the frame 1. Transmission wheel A drives the lower polyurethane friction wheel to rotate through a transmission shaft; transmission wheel B drives the upper polyurethane friction wheel to rotate through a transmission shaft; transmission wheel A and transmission wheel B are both made of cast iron, which is stable in performance and not easy to deform. The surface of transmission wheel A is grooved according to the shape of the transmission belt, and transmission wheel B has chamfers on both sides of the wheel to prevent the belt from deviating. When the V-shaped elastic wheel contacts the bowling ball, the two sides of the V shape will elastically deform (the distance between the friction wheel and the lifting fixture is less than the diameter of the bowling ball), which will generate a counteracting force on the bowling ball, pressing the bowling ball tightly on the lifting fixture without slipping. When the friction wheel rotates, the bowling ball also rotates with it.

[0038] Referring to Figures 1-3 The lifting plate 3 includes a polyurethane plate 31 arranged near the spherical object and a steel plate 32 connected to the polyurethane plate 31. The steel plate provides support to ensure the movement trajectory of the bowling ball, and the polyurethane is softer than the bowling ball, which can provide a larger friction force when the surface contacts the bowling ball. The upper and lower layers are fixed together by bolts, and the fixing bolts are on both sides of the polyurethane to avoid the contact position between the polyurethane and the bowling ball.

[0039] Referring to Figures 1-3 The bottom of the frame 1 is provided with an adjusting plate 7, which adjusts the height by an internal hexagonal nut. The traditional foot cup adjustment method is generally below, while the adjusting plate 7 can be adjusted in height by a hexagonal wrench above.

Through the shock-absorbing effect of the two shock-absorbing rubber pads, the vibration of the motor itself is isolated from the frame, and the conduction of the vibration is greatly reduced.

[0041] Specific working process:

[0042] The driving wheel is installed on the output shaft of the motor. The motor rotates to drive the driving wheel to rotate, and the driving wheel drives the transmission wheels A and B to rotate through the transmission belt. Because the contact surface of the transmission wheel A and the transmission belt is the same as that of the driving wheel and the transmission belt, the transmission wheel A and the driving wheel rotate in the same direction. Because the contact surface of the transmission wheel B and the transmission belt is opposite to that of the driving wheel and the transmission belt, the transmission wheel B and the driving wheel rotate in opposite directions. That is, the driving wheel drives the transmission wheels A and B to rotate in different directions through the different contact surfaces of the transmission belt. The rotation is transmitted to the friction wheels by the transmission shaft respectively.

[0043] When the bowling ball enters the ball inlet of the elevator from the lower opening, the lower polyurethane friction wheel drives the bowling ball to the position between the lower polyurethane friction wheel and the upper polyurethane friction wheel, and the upper polyurethane friction wheel rotates in the opposite direction to drive the bowling ball to the upper side supporting piece, and finally the bowling ball rolls out from the ball outlet.

[0044] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
