TECHNICAL FIELD

[0001] The application belongs to the field of logistics conveying equipment, and particularly relates to a roller conveying equipment. BACKGROUND

[0002] With the increasing demand for logistics, more and more goods need to be transported through the roller conveying line, for example, the box type logistics roller conveying line. In the transportation process, the goods need to be transported in the vertical direction, so the in-carriage roller conveying line equipment is derived. However, due to the heavy and high-frequency transportation of goods, the roller conveying line may be blocked and stopped, which leads to the decrease of transportation efficiency and greatly limits the stability and efficiency of the roller conveying line transmission system. Therefore, manual maintenance is needed. However, the hoist used in the roller conveying line equipment does not belong to the category of special equipment, so the maintenance personnel cannot enter the carriage to check and maintain the in-carriage roller conveying line. In order to ensure the safety of the maintenance personnel and improve the efficiency of the maintenance of the in-carriage roller conveying line equipment, the industry needs a roller conveying line that can be maintained without entering the carriage.

For example Figure 2 , the upper roller conveyor 02 is pulled out for maintenance mode.

[0009] As shown in Figure 3 , the car load-bearing frame is composed of left and right frames, and the maintenance leg retraction device is arranged on the left and right frames, which specifically includes a left load-bearing frame 101, a right load-bearing frame 102, and a maintenance leg retraction device 103.

[0010] As shown in Figure 4 , the upper roller conveyor is composed of a first electric roller 201, a first non-powered roller 202, a first roller frame 203, a first roller frame spacing fixing frame 204, a first side guide wheel 205, a first bottom sliding roller 206, a first guardrail 207, and a maintenance leg 208. Among them, the first roller frame 203 preferably can adopt the roller frame with adjustable center distance in the prior art, which is convenient for adjusting the spacing between adjacent rollers, and the first roller frame 203 and the first roller frame spacing fixing frame 204 form a first plane frame, which serves as the main frame of the upper roller conveyor.

[0011] The first electric roller and the first unpowered roller are arranged on the first plane frame, power is provided by the first electric roller, and power is synchronized to the first unpowered roller by a multiple-belt drive. The first electric roller and the first unpowered roller can be arranged alternately or in multiple, which is comprehensively considered according to the power demand. The first side guide wheel is arranged on the outer side of the first roller frame 203, and the first side guide wheel is in contact with the inner side of the load-bearing frame in the car, so that the distance between the roller conveying line and the load-bearing frame in the car is kept uniform. The first side guide wheel can be a position-adjustable guide wheel to adjust the optimal stress position as needed. The first bottom sliding roller is arranged at the bottom of the first roller frame and can be in contact with and roll on the upper side of the load-bearing frame in the car. The sliding friction is changed to rolling friction to reduce the friction and facilitate the extraction of the upper roller conveying line. The first guardrail is arranged on the first plane frame and maintains a stable distance, so that the goods can be prevented from deviating from the predetermined transmission path. The first guardrail can be a structure with adjustable distance to facilitate the transportation of goods of different sizes. The maintenance leg is arranged on the first plane frame and connected to the first plane frame through the connecting plate 501. The connecting plate 501 is fixedly connected to the first plane frame, and the connecting plate 501 is hingedly connected to the maintenance leg 208. When the equipment needs to be maintained, the system maintenance mode is opened. At this time, the upper roller conveying line can be extracted. When extracted, the maintenance leg is lowered under the action of gravity to support. When the maintenance is completed, the upper conveying line is pushed horizontally into the car, the maintenance leg 208 is in contact with the maintenance leg retraction device 103 in the Figure 3 , and the maintenance leg 208 can move along the surface of the maintenance leg retraction device 103 to reach the horizontal state, so as to be retracted.

[0012] Meanwhile, the first safety limiting device 209 and the first positioning magnetic attraction switch 2010 can also be arranged on the upper roller conveying line. The safety limiting device and the positioning magnetic attraction switch can be used in the prior art. The safety limiting device and the magnetic attraction switch are connected to the electrical system of the equipment and matched with the load-bearing frame in the car. When the entire conveying line equipment is in normal use, the magnetic attraction switch is extended to cooperate with the positioning hole of the load-bearing frame in the car to ensure that the positioning of the upper roller conveying line is not moved randomly. When the entire conveying line equipment needs to be maintained, the equipment is stopped, the magnetic attraction switch is retracted, the upper roller conveying line can be removed for maintenance, and after the maintenance is completed, the upper roller conveying line is pushed in. The safety limiting device acts on the load-bearing frame in the car. After the safety limiting device is in place and the magnetic attraction switch lock tongue reenters the positioning hole, the entire equipment can be restored to normal use.

[0013] As shown in Figure 5As shown, the lower roller conveying line 03 comprises a second motorized roller 301, a second non-motorized roller 302, a second roller frame 303, a second roller frame spacing fixing frame 304, a second side guide wheel 305, a second bottom sliding roller 306, and a second guardrail 307. The second roller frame 303 and the second roller frame spacing fixing frame 304 form a second plane frame, and the second motorized roller 301, the second non-motorized roller 302, the second side guide wheel 305, the second bottom sliding roller 306, and the second guardrail 307 are sequentially arranged on the second plane frame. The second side guide wheel 305 is arranged on the outer side of the second roller frame 303 and can abut the inner side of the inner load-bearing frame 01 in the car. The second bottom sliding roller 306 is arranged at the bottom of the second roller frame 303 and can abut the inner load-bearing frame 01 in the car.

[0014] The second motorized roller and the second non-motorized roller can be arranged one by one or one by multiple, which is comprehensively considered according to the power demand. The second side guide wheel can be a position-adjustable guide wheel to adjust the optimal stress position as needed. The second bottom sliding roller is arranged at the bottom of the second roller frame and can abut and roll on the inner load-bearing frame in the car. The friction is reduced by changing the sliding friction to rolling friction, which facilitates the extraction of the lower roller conveying line. The second guardrail is arranged on the second plane frame to maintain a stable spacing, thereby preventing the goods from deviating from the predetermined transmission path. The second guardrail can be a spacing-adjustable structure to facilitate the transportation of goods of different sizes.

[0015] Meanwhile, preferably, the lower roller conveying line can further comprise a second safety limiting device 308 and a second positioning magnetic attraction switch 309, which are arranged on the second roller frame 303. The safety limiting device and the positioning magnetic attraction switch can be of existing technology. The safety limiting device and the magnetic attraction switch are connected to the electrical system of the equipment and matched with the inner load-bearing frame in the car. When the conveying line equipment is in normal use, the magnetic attraction switch extends to cooperate with the positioning hole of the inner load-bearing frame in the car to ensure that the positioning of the lower roller conveying line is not moved at will. When the conveying line equipment needs to be repaired, the equipment stops, the magnetic attraction switch is retracted, and the lower roller conveying line can be removed for repair. After the repair is completed, the lower roller conveying line is pushed in, the safety limiting device acts on the inner load-bearing frame in the car, and after the safety limiting device is in place and the magnetic attraction switch lock tongue reenters the positioning hole, the entire equipment can be restored to normal use.
