detailed description

In the following, the present invention will be further described with reference to the drawings and specific implementations. It should be noted that, provided that there is no conflict, the following embodiments or technical features can be combined to form new embodiments. .

A two-way climbing machine can be driven by a two-way transmission mechanism 3 and the transmission chain 4 on the climbing machine can rotate in two directions, so that the goods on the climbing machine can be transported in two directions.

In this embodiment, the two-way climbing machine includes a frame 1, a driven mechanism 2, a two-way transmission mechanism 3, and a transmission chain 4.

As shown in Figures 1 and 2, the two ends of the frame 1 extend in the horizontal direction to form two horizontal sections, the middle of which has an inclination angle to form an inclined section, so that the frame 1 is first horizontal and then inclined from bottom to top. In a further horizontal state, the frame 1 can be docked with other transportation platforms or conveyor belts through the horizontal section, and the middle of the frame 1 is inclined so that the goods can be climbed or dropped along the climber, and the goods can be transported to different heights. A number of idler assemblies 101 parallel to each other and with a certain height difference are arranged on the frame 1. The distribution of the several idler assemblies 101 on the frame 1 coincides with the inclination angle of the frame 1, and the transmission chain 4 is set in After a number of roller assemblies 101, the transmission chain 4 also has a horizontal section and an inclined section. In this embodiment, the transmission chain 4 is configured as a modular transmission chain 4, which is spliced into a complete transmission chain 4 through multiple modules. , So that the transmission chain 4 does not leave a gap at the junction of the horizontal section and the inclined section. Driven by the transmission chain 4, the goods can climb more smoothly when the goods are transported from the horizontal section to the inclined section, so as to avoid the accumulation of goods.

A driven mechanism 2 is provided at both ends of the frame 1. The driven mechanism 2 can assist the transmission chain 4 to rotate; in this embodiment, the driven mechanism 2 includes a rotating shaft and a number of gears sleeved outside the rotating shaft. The two ends of the shaft are fixed on the side wall of the frame 1 through bearings. The transmission chain 4 surrounds the driven mechanism 2, and a number of card slots are opened on the lower surface of the transmission chain 4, and the number of card slots are distributed in a matrix. The distance between adjacent grooves in the row of grooves is consistent with the distance between adjacent gears on the rotating shaft, and the distance between adjacent grooves in each row of grooves corresponds to the tooth pitch of the gear on the rotating shaft , So that when the transmission chain 4 rotates, the gear can be driven to rotate with the rotating shaft as the axis, which reduces the friction between the transmission chain 4 and the driven mechanism 2 and improves the smoothness of the transmission chain 4 transportation.

After the transmission chain 4 surrounds the driven mechanism 2 at both ends of the frame 1 and several roller assemblies 101, it passes through the two-way transmission mechanism 3 under the bend of the transmission chain 4 to form a complete transmission chain 4 that is connected end to end. The arrangement of the mechanism 3 at the bend of the transmission chain 4 can keep the transmission chain 4 at the bend in a tight state, and prevent the transmission chain 4 from being loose at the bend or in the middle, which affects the transportation performance of the transmission chain 4.

The two-way transmission mechanism 3 includes a driving wheel 301 and two supporting wheels 302. One supporting wheel 302 is arranged below the bend of the transmission chain 4 and located close to the driven mechanism 2, and the other supporting wheel 302 is arranged on the supporting wheel. At the bottom left of 302, there is a certain height difference between the two supporting wheels 302, and there is a certain gap between the two supporting wheels 302, and a driving wheel 301 is arranged in the gap, and a number of gears are sleeved on the driving wheel 301. The gear on the driving wheel 301 engages with the slot at the bottom of the transmission chain 4, and the end of the driving wheel 301 is connected to the bidirectional driving device 303. The bidirectional driving device 303 can rotate clockwise or counterclockwise, so that the transmission chain 4 can be rotated. Realize two-way transportation.

The diameter of the two supporting wheels 302 is larger than the diameter of the driving wheel 301, and the diameter of the supporting wheel 302 is 2 to 4 times the diameter of the gear on the driving wheel 301. In this embodiment, the diameter of the supporting wheel 302 is the diameter of the driving wheel 301. 2.5 times the diameter of the gear increases the contact area between the transmission chain 4 and the supporting wheel 302, increases the contact friction between the supporting wheel 302 and the transmission chain 4, so that the supporting wheel 302 has a more obvious effect of pulling the transmission chain 4. The transmission chain 4 passes through the outer surface of a supporting wheel 302 and then surrounds the driving wheel 301, and then passes through the outer surface of another supporting wheel 302 to extend toward the driven mechanism 2, so that the transmission chain 4 under the frame 1 is still tight. The tensioned state makes the structure of the transmission chain 4 on the climber more compact; and when the bidirectional drive device 303 drives the driving wheel 301 to rotate, the driving wheel 301 is located near the middle of the transmission chain 4, so that the power of the driving wheel 301 can act more timely On the transmission chain 4, the transmission chain 4 can be more timely when changing the transportation direction, and at the same time, the driving energy consumption of the driving device can be reduced, and the commutation efficiency can be improved.

In order to make the transmission between the driving wheel 301 and the transmission chain 4 closer, the axis of the driving wheel 301 is set below the line where the axis of the two supporting wheels 302 is located, so that the transmission chain 4 and the driving wheel 301 are in contact with each other. The area is increased, and more teeth on the driving wheel 301 are added to engage with the transmission chain 4, thereby improving the transmission capacity of the driving wheel 301. In this embodiment, the horizontal tangent to the upper apex of the supporting roller 302 at a height is always higher than the horizontal tangent to the lower apex of the driven mechanism 2 at the height of the frame 1, thereby increasing the transmission chain 4 and the supporting rollers. The increase of the contact area of 302 can increase the contact friction force between the supporting wheel 302 and the transmission chain 4, so that the supporting wheel 302 can better guide the extension direction and angle of the transmission chain 4.

The inclination angle of the axis of the two supporting wheels 302 is the same as the inclination angle of the frame 1, so that after the transmission chain 4 passes through the supporting wheels 302 and surrounds the driving wheel 301, the transmission chain 4 can still be close to the frame 1, and The racks 1 are kept parallel to each other to better maintain the tightness of the transmission chain 4.

The inclination angle of the frame 1 is 10°～45°, that is, the goods can climb or fall along the angle of 10～45°. In order to avoid the phenomenon of goods slipping during the climbing or descent, the transmission chain 4 The upper surface is provided with a plastic film 5, which is vertically fixed on the transmission chain 4; the goods can be placed on the plastic film 5, and the plastic film 5 is squeezed and laid flat between the goods and the upper surface of the transmission chain 4. Increase the static friction between the goods and the transmission chain 4, so that the goods will not easily slip off; the goods can also be placed in the gap between adjacent plastic films 5, the bottom of the plastic film 5 is in contact with the goods, and the friction is greater. The plastic film 5 can prevent the cargo from sliding down. When the plastic film 5 passes through the supporting roller 302, it is squeezed and spreads flat on the surface of the transmission chain 4, which will not affect the normal operation of the transmission chain 4, and will return to the state of being perpendicular to the transmission chain 4 without being squeezed by external force. Continue to limit the transportation of goods to prevent the goods from sliding down during the climb or descent process, which will affect the accumulation of goods and affect the normal transportation order.

The foregoing embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the present invention. The scope of protection required.
