[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and the following embodiments.

[0026] This embodiment provides a pulley device applied to a conveyor track, such as Figure 1As shown, the pulley device includes a U-shaped bracket 1, a pulley 2 is provided at the top end of the U-shaped bracket 1, and the pulley 2 is rollingly connected to the track 3.

[0027] The material of the U-shaped bracket is not specifically limited, the track includes a horizontal track, an inclined track, or a combination of a horizontal track and an inclined track, the pulley is rotatably connected to the U-shaped bracket, and the pulley can roll on the track.

[0028] In certain embodiments, such as Figure 2 As shown, a transmission part 4 moving along the track 3 is provided on the track 3, and a transmission connecting part 5 connected to the transmission part 4 is provided on the U-shaped bracket 1. Preferably, the transmission part 4 is a chain, and the transmission connecting part 5 is a step tooth plate, which is inserted into two adjacent links of the chain.

[0029] The chain can be driven by a sprocket and a motor, and the number of pulley devices is preferably an even number, such as Figure 1 The two pulleys shown are stuck on both sides of the track and can rotate and slide on the track. The step tooth piece is arranged at the bottom of the U-shaped bracket. The connection method is not specifically limited. The pulleys are stuck on both sides of the track and can rotate and slide on the track. The step tooth piece is arranged at the bottom of the U-shaped bracket. The transmission part can also include other components that can realize the transmission of the U-shaped bracket, and the transmission connection part can also include other components connected to the transmission part. When in use, when the track has only one section, only one pulley device is used to achieve it. The driving mechanism drives the active wheel to rotate, driving the driving chain to rotate. Since the pulley is rollingly connected to the inclined track, the step tooth piece is inserted into two adjacent links of the driving chain and coupled with the driving chain, so the rotation of the driving chain can drive the U-shaped bracket to move forward, so as to achieve the purpose of transporting the hanger. When the track includes at least two sections, two pulley devices are required. When one pulley slides on one track, the other pulley is able to cross the gap between the two sections of the track.

[0030] In some embodiments, the step tooth plate includes at least 3 tooth plates.

[0031] This embodiment ensures that the pulley device can be smoothly transmitted on the segmented track (two adjacent tracks) by limiting the step tooth plates to include at least three tooth plates.

[0032] In certain embodiments, such as Figure 3 As shown, the U-shaped bracket 1 includes a first bracket 6 and a second bracket 7 that are symmetrically arranged, and a pulley 2 is arranged at the top of each of the first bracket 6 and the second bracket 7. Preferably, at least two fixed shafts 8 are arranged at the bottom opposite to the side walls of the first bracket 6 and the second bracket 7. Figure 4 As shown, a through hole 9 is provided on the step tooth plate for the fixed shaft 8 to pass through.

[0033] This embodiment fixes the step tooth piece on the U-shaped bracket by setting a fixed shaft, which can achieve the purpose of detachability and easy installation. When a certain accessory is damaged, it can be replaced to avoid overall replacement and reduce the cost. It can also maintain the gravity balance of the hanger beam under the U-shaped bracket and the left and right gravity balance of the pulley device in the walking direction, and can swing appropriately in the left and right directions and also be balanced in the center.

[0034] In certain embodiments, such as Figure 5 As shown, the pulley 2 is connected to the U-shaped bracket 1 via a rotating shaft 10. Preferably, the axis of the rotating shaft 10 forms an angle of 100°-170° with the first bracket 6 or the second bracket 7.

[0035] In certain embodiments, such as Figure 1 As shown, the included angle α between the rotating shaft 8 and the U-shaped bracket 1 satisfies 90°<α<180°.

[0036] In certain embodiments, such as Figure 6 As shown, a hanger beam 11 is provided at the bottom end of the U-shaped bracket 1, and a first connecting member 12 is provided at the top end of the hanger beam 11. The first connecting member 12 is connected to a second connecting member 13 at the bottom end of the U-shaped bracket 1. The first connecting member 12 can swing back and forth with the second connecting member 13 as the center, and the first connecting member 12 can rotate horizontally relative to the hanger beam 11.

[0037] The second connecting member defined in this embodiment can be a component with a through hole, and the first connecting member can be set to a sheep eye screw, so that when the hanger beam runs on the track, it can swing at a certain angle relative to the U-shaped bracket, and when the track is an inclined track, it can better achieve climbing.
