Technical Field
[0001] This utility model patent belongs to the field of logistics conveying equipment, specifically relating to a roller conveying equipment. Background Technology
[0002] With the increasing demand for logistics, taking box-type logistics roller conveyor lines as an example, more and more goods need to be transported through roller conveyor lines. In the transportation process, vertical transportation situations are encountered, thus giving rise to roller conveyor equipment inside the car. However, due to the heavy and frequent transportation of goods, roller conveyor lines may experience jamming and stoppage, resulting in a decrease in transportation efficiency, which greatly limits the stability and efficiency of the roller conveyor transmission system. Therefore, manual maintenance is required. However, since the hoist used by the roller conveyor equipment is not classified as special equipment, maintenance personnel cannot enter the car to inspect and repair the roller conveyor inside the car. To ensure the safety of maintenance personnel and improve the efficiency of maintenance of roller conveyor equipment inside the car, the industry needs a roller conveyor that can be maintained without entering the car. Utility Model Content
[0003] In view of the above-mentioned situation and existing problems, this utility model proposes a movable maintenance roller conveyor line inside the car.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a movable maintenance roller conveyor line inside a car, comprising a load-bearing frame inside the car, an upper roller conveyor line, and a lower roller conveyor line. Both the upper and lower roller conveyor lines are movably mounted on the load-bearing frame inside the car, and the load-bearing frame can be installed inside the car of a lifting device.
[0005] The beneficial effects of this utility model are as follows: This movable maintenance roller conveyor line inside the car provides a simpler and safer maintenance method while maintaining the original transportation function. The movable maintenance roller conveyor line inside the car can be pulled out for maintenance, avoiding the dangerous situation of maintenance personnel having to enter the car to perform maintenance when the equipment malfunctions. It eliminates the inconvenience of maintenance previously associated with roller conveyor lines inside the car, realizing the function of removing the roller conveyor line for maintenance, ensuring the safety of maintenance personnel and equipment, expanding the maintenance space, and improving the efficiency of equipment maintenance.
[0006] Both the upper and lower roller conveyor lines can be individually and movablely pulled out from the load-bearing frame inside the car, allowing for maintenance outside the lifting equipment car, which is safer.
[0007] In some embodiments, the upper roller conveyor line and the lower roller conveyor line may include a certain number of parallel rollers; the upper roller conveyor line is provided with bottom sliding rollers, side guide rollers, and maintenance support legs. The bottom sliding rollers and side guide rollers allow the roller conveyor line to be smoothly pulled out or put back on the load-bearing frame inside the car. When the equipment is under maintenance, the maintenance support legs will be lowered when the upper roller conveyor line is pulled out; the lower roller conveyor line is provided with bottom sliding rollers and side guide rollers, which allow the lower roller conveyor line to be smoothly pulled out or put back on the load-bearing frame inside the car.

Figure 1 , Figure 2 As shown, it includes an upper roller conveyor line 02, a lower roller conveyor line 03, and a load-bearing frame 01 inside the car; all three can be located inside the car of the lifting equipment, such as... Figure 1 As shown, under normal use, it serves to support goods; such as Figure 2 As shown, when maintenance is required on the roller conveyor line, the roller conveyor line can be pulled out horizontally, thereby moving the equipment outside the car for maintenance. For example... Figure 2 The image shows the upper roller conveyor line 02 being put into maintenance mode.
[0009] like Figure 3 As shown, the load-bearing frame inside the car consists of two frames, left and right. The maintenance outrigger retraction device is installed on the two frames, specifically including the left load-bearing frame 101, the right load-bearing frame 102, and the maintenance outrigger retraction device 103.
[0010] like Figure 4 As shown, the upper roller conveyor line consists 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 maintenance support legs 208. Preferably, the first roller frame 203 can be an adjustable center-distance roller frame from the prior art, facilitating adjustment of the spacing between adjacent rollers. The first roller frame 203 and the first roller frame spacing fixing frame 204 form a first planar frame, which serves as the main frame of the upper roller conveyor line.
[0011] A first electrically powered roller and a first unpowered roller are mounted on the first planar frame. The first electrically powered roller provides power, which is synchronized to the first unpowered roller using a multi-wedge belt. The first electrically powered roller and the first unpowered roller can be installed alternately or alternately, depending on the power demand. A first side guide wheel is mounted on the outer surface of the first roller frame 203, and the first side guide wheel contacts the inner side of the load-bearing frame inside the car, ensuring a uniform distance between the roller conveyor line and the load-bearing frame inside the car. The first side guide wheel can be configured as an adjustable guide wheel to adjust to the optimal force position as needed. The first bottom sliding roller is located at the bottom of the first roller frame and can contact and roll against the upper side of the load-bearing frame inside the car. By changing sliding friction to rolling friction, the friction is reduced, facilitating the extraction of the upper roller conveyor line. The first guardrail is set on the first plane frame, maintaining a stable spacing to prevent goods from deviating from the predetermined transmission path. The first guardrail can be configured with an adjustable spacing to accommodate goods of different sizes. The maintenance support leg is set on the first plane frame and connected to it via a connecting plate 501. The connecting plate 501 is fixed to the first plane frame and hinged to the maintenance support leg 208. When the equipment needs maintenance, the system maintenance mode is activated, and the upper roller conveyor line can be extracted. During extraction, the maintenance support leg is lowered by gravity, thus providing support. When maintenance is complete, the upper conveyor line is pushed horizontally into the car, and the maintenance support leg 208 and... Figure 3 The maintenance outrigger 208 is in contact with the maintenance outrigger retraction device 103, and can move along the surface of the maintenance outrigger retraction device 103 to reach a horizontal state, thereby retracting.
[0012] Preferably, a first safety limit device 209 and a first positioning magnetic switch 2010 can also be installed on the upper roller conveyor line. Both the safety limit device and the positioning magnetic switch can be based on existing technology. The safety limit device and the magnetic positioning switch are connected to the equipment's electrical system and operate in conjunction with the load-bearing frame inside the car. When the entire conveyor line is in normal use, the magnetic switch extends and engages with the positioning hole of the load-bearing frame inside the car, ensuring that the positioning of the upper roller conveyor line does not move arbitrarily. When the entire conveyor line needs maintenance, the equipment stops, the magnetic switch retracts, and the upper roller conveyor line can be removed for maintenance. After maintenance is completed, the upper roller conveyor line is pushed back in, and the safety limit device engages with the load-bearing frame inside the car. Once the safety limit device is in place and the magnetic switch latch re-enters the positioning hole, the entire equipment can then resume normal operation.
[0013] like Figure 5As shown, the lower roller conveyor line 03 includes a second electric roller 301, a second non-powered 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 planar frame. The second electric roller 301, the second non-powered 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 planar frame. The second side guide wheel 305 is located on the outer side of the second roller frame 303 and can abut against the inner side of the load-bearing frame 01 inside the car. The second bottom sliding roller 306 is located at the bottom of the second roller frame 303 and can abut against the load-bearing frame 01 inside the car.
[0014] The second electric roller and the second non-powered roller can be installed alternately or alternately, depending on the power requirements. The second side guide wheel can be configured as an adjustable guide wheel to adjust to the optimal force position as needed. The second bottom sliding roller is located at the bottom of the second roller frame and can contact and roll with the load-bearing frame inside the car. By changing sliding friction to rolling friction, the friction is reduced, facilitating the extraction of the lower roller conveyor line. The second guardrail is installed on the second planar frame to maintain a stable spacing, thereby preventing goods from deviating from the predetermined transmission path. The second guardrail can be configured with an adjustable spacing structure to accommodate the transportation of goods of different sizes.
[0015] Preferably, a second safety limit device 308 and a second positioning magnetic switch 309 can also be installed on the lower roller conveyor line. The second safety limit device 308 and the second positioning magnetic switch 309 are mounted on the second roller frame 303. Both the safety limit device and the positioning magnetic switch can be based on existing technology. The safety limit device and the magnetic positioning switch are connected to the equipment's electrical system and operate in conjunction with the load-bearing frame inside the car. When the entire conveyor line is in normal use, the magnetic switch extends and engages with the positioning hole of the load-bearing frame inside the car, ensuring that the lower roller conveyor line is positioned and does not move arbitrarily. When the entire conveyor line needs maintenance, the equipment stops, the magnetic switch retracts, and the lower roller conveyor line can be removed for maintenance. After maintenance, the lower roller conveyor line is pushed back in, the safety limit device engages with the load-bearing frame inside the car, and after the safety limit device is in position and the magnetic switch latch re-enters the positioning hole, the entire equipment can then resume normal operation.
[0016] like Figure 6As shown, the outrigger retraction device 103 includes a left outrigger push rod roller 401, a right outrigger push rod roller 402, and an outrigger fixing rod 403. The left outrigger push rod roller 401 and the right outrigger push rod roller 402 are respectively fixed to the left load-bearing frame 101 and the right load-bearing frame 102. The two ends of the outrigger fixing rod 403 are respectively connected to the left outrigger push rod roller 401 and the right outrigger push rod roller 402. The left outrigger push rod roller and the right outrigger push rod roller interact with the outrigger, so that after the equipment is repaired, the outrigger moves tangentially along the roller surface, which reduces the force. After the equipment is in place, the outrigger fixing rod will restrain the outrigger from moving downward.
[0017] like Figure 7 As shown, the maintenance outrigger 208 includes a connecting plate 501, an outrigger 502, a connecting rod 503, a caster 504, and an outrigger connecting rod 505. The outrigger 502 is hinged to the connecting plate, which is hinged to two holes in the upper roller conveyor line. The outrigger rotates around the hinged holes. The outrigger 502 is connected to the upper roller conveyor line via a connecting rod. This connecting rod can be a conventional two-fold connecting rod. When the outrigger is lowered, one end of the two-fold connecting rod moves along the irregular hole on the upper roller conveyor line frame. When the two-fold connecting rod is fully extended, the upper conveyor line is lowered, and the two-fold connecting rod... Upon reaching the dead point, the support point will be automatically reached. When the outrigger is retracted, the two-fold connecting rod is manually released, and the outrigger moves along the maintenance outrigger retraction device, subsequently pushing the upper roller conveyor line into the load-bearing frame inside the car. At this time, the outrigger is constrained by the outrigger fixing rod, thereby preventing the outrigger from falling and affecting the normal use of the equipment. The casters in this patent can be directional casters, which are set on the outrigger and fixed to the outrigger, facilitating the movement of the upper roller conveyor line in maintenance mode. The outrigger connecting rod connects the two outriggers, ensuring that the two outriggers move in a consistent manner.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
