Description

Technical Field

[0001] The utility model belongs to the technical field of cargo unloading equipment, in particular to an unloading rack for transportation. Background Art

[0002] An unloading rack is a device specifically used for unloading goods. It is usually used in the loading and unloading links of logistics transportation and warehousing. Its main function is to help workers unload goods quickly and safely, thereby improving work efficiency, reducing labor intensity, and reducing the risk of accidents. In most usage scenarios, workers need to place the unloading rack at the rear end of the carriage and fix it so that it is stably connected to the carriage. Then the workers place the goods in the carriage on the unloading rack one by one. The unloading rack actively or passively moves the goods to a lower position, and a dedicated person transfers the goods.

[0003] However, in the prior art, when unloading goods, the goods may not be able to slide down. At the same time, when unloading goods, some fragile items may be unloaded, and the speed of the goods falling cannot be slowed down during unloading, resulting in damage to the goods.

[0004] The Chinese patent with the authorization announcement number CN219078358U discloses an unloading rack for logistics cargo transportation, including a bottom plate, two symmetrical cylinders 1 are fixedly connected to one side of the top of the bottom plate, and two symmetrical cylinders 2 are fixedly connected to the other side of the top of the bottom plate. The output ends of cylinders 1 and 2 are fixedly connected with hinged joints, and the hinged joints are hinged with hinged seats through rotating shafts 1, and the top of the hinged seats are fixedly connected with support plates. The utility model provides a groove 2, and a baffle is rotatably connected in the groove 2. The baffle is connected to the groove 2 through a spring, so as to block the falling cargo and achieve the effect of decelerating the cargo, thereby protecting the cargo to a certain extent; by removing the baffle rod from the top of the vertical plate, putting the through hole on the vertical plate, and then rotating the baffle rod to compress the baffle into the groove 2, and then fixing the baffle rod to one side of the vertical plate through an insertion rod, the rapid falling of some cargo can be achieved.

[0005] However, the above has the following shortcomings:

[0006] The above patent uses a free-rolling roller to change the sliding friction between the goods and the unloading rack into rolling friction, thereby reducing the friction between the goods and the unloading rack and allowing the goods to slide more smoothly. However, in actual use, the goods - especially bagged granular goods - are easily stuck in the gaps between the rollers, making it still difficult for the goods to slide down, affecting the efficiency of the unloading work.

[0007] The above patent manually removes the baffle rod and switches the state of the unloading rack, so that the baffle extends out of fragile or dangerous goods to slow down and cushion the goods, avoiding damage to the goods or causing safety risks. However, the above switching process is not flexible enough, the switching method is cumbersome and wastes labor and time, which is particularly troublesome when unloading mixed goods. Utility Model Content

[0008] The utility model solves the technical problem of adopting a method of actively rotating the rollers to push the goods to slide down, thereby effectively preventing the goods from staying on the unloading rack, and utilizing the ratchet sleeve to apply a unidirectional friction force to the goods when the goods stop, so that when the goods stop, the ratchet sleeve increases the friction with the goods, and cooperates with the rollers to push the goods to slide down, and when the goods slide on their own, the friction between the ratchet sleeve and the goods is reduced, so that the goods can slide down quickly and efficiently, and when the goods are stuck in the gap between the rollers, the abutment plate can be controlled to flip and push the goods out of the gap and slide again, effectively solving the problem of the goods being stuck on the unloading rack and affecting the work efficiency, and when dangerous and fragile goods need to be unloaded, the ratchet plate is used to contact with the bottom side of the goods to provide friction, thereby slowing down the goods in the process of sliding down, thereby achieving the effect of protecting the goods, and the utility model is simple, easy to control, and flexible to operate.

[0009] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transport unloading rack, comprising a support frame, a plurality of rollers are evenly distributed and rotatably connected between the two sides of the support frame, a plurality of collars are evenly distributed and fixedly connected to each of the rollers, a ratchet sleeve is fixedly connected to each roller between two adjacent collars, abutments are rotatably connected to both ends of each roller, a ratchet plate is fixedly connected to each abutment plate, the ratchet sleeve and the ratchet plate are made of soft and elastic material, the ratchet tips on the surface of the ratchet sleeve are oriented in the same direction as the tangent direction of the roller rotation direction, the ratchet tips on the surface of the ratchet plate are oriented in the opposite direction to the direction in which the goods slide, and a first side shell and a second side shell are fixedly connected to the two sides of the support frame respectively.

[0010] The roller actively rotates to push the goods down, and the ratchet sleeve rotates with the roller to apply a unidirectional friction force to the goods, so that the goods can slide down quickly and efficiently, effectively preventing the goods from staying on the unloading rack.

[0011] The goods stuck in the gap between the rollers can be pushed out by controlling the abutment plate, so that the goods can escape from the gap and slide again, effectively solving the problem of goods stuck on the unloading rack affecting work efficiency.

[0012] When dangerous and fragile goods need to be unloaded, the ratchet plate is used to contact the bottom side of the goods to provide friction, thereby slowing down the goods as they slide down, thereby protecting the goods.

[0013] Furthermore, each of the abutment plates is fixedly connected to an end of the first side shell near the first side shell, a sliding groove is provided in each of the swing arms, a sliding pin is slidably connected in each of the swing arms, a plurality of the sliding pins are fixedly connected to a push plate, the push plate is slidably connected to the first side shell, a push groove is provided on the first side shell at a position corresponding to the push plate, a push block fixedly connected to the push plate is slidably connected in the push groove, a first electric push rod is fixedly connected to the outer side of the first side shell, and an extended end of the first electric push rod is fixedly connected to the push block.

[0014] By setting the push plate and the swing arm, the control of the impact plate is simple and easy to control, and the operation is flexible, which greatly saves working time and labor and improves the unloading efficiency.

[0015] Furthermore, each of the rollers is fixedly connected to a driven wheel at one end close to the second side shell, and two adjacent driven wheels are connected via a transmission belt. A motor is fixedly connected to the outer side of the second side shell, and the output end of the motor extends into the second side shell and is connected to a driving wheel.

[0017] By providing a second electric push rod, the height of the support frame can be adjusted according to actual conditions, so as to adapt to the height of various vehicles and improve the application range of the equipment.

[0018] In summary, compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0032] Embodiment 1:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, a transport unloading rack includes a support frame 10, and a plurality of rollers 27 are evenly distributed and rotatably connected between the two sides of the cargo support frame 10, and a plurality of collars 11 are evenly distributed and fixedly connected to each cargo roller 27, and a ratchet sleeve 12 is fixedly connected to each cargo roller 27 between two adjacent collars 11, and abutment plates 28 are rotatably connected to both ends of each cargo roller 27, and a ratchet plate 13 is fixedly connected to each cargo abutment plate 28, and the cargo ratchet sleeve 12 and the ratchet plate 13 are made of soft elastic material, and the ratchet tip on the surface of the cargo ratchet sleeve 12 faces the same direction as the tangent direction of the rotation direction of the roller 27, and the ratchet tip on the surface of the cargo ratchet plate 13 faces the opposite direction to the direction of the cargo sliding, and a first side shell 17 and a second side shell 18 are fixedly connected to the two sides of the cargo support frame 10, respectively.

[0034] like Figure 5 and Figure 6 As shown, each cargo stop plate 28 is fixedly connected to one end of the cargo stop plate 28 close to the first side shell 17 with a swing arm 30, a slide groove 31 is provided in each cargo swing arm 30, a slide pin 29 is slidably connected in each cargo swing arm 30, a plurality of cargo slide pins 29 are fixedly connected to a push plate 25, the cargo push plate 25 is slidably connected to the first side shell 17, a push groove 19 is provided on the first cargo side shell 17 at a position corresponding to the push plate 25, a push block 20 fixedly connected to the push plate 25 is slidably connected in the cargo push groove 19, a first electric push rod 21 is fixedly connected to the outer side of the first cargo side shell 17, and the extended end of the first electric push rod 21 for cargo is fixedly connected to the push block 20.

[0035] By providing the push plate 25 and the swing arm 30, the control of the abutment plate 28 is simple and easy to control, and the operation is flexible, which greatly saves working time and labor and improves the working efficiency of unloading.

[0036] like Figure 7 As shown, each cargo roller 27 is fixedly connected to a driven wheel 32 at one end close to the second side shell 18, and two adjacent driven wheels 32 are connected by a transmission belt 33. A motor 26 is fixedly connected to the outer side of the second cargo side shell 18, and the output end of the cargo motor 26 extends into the second side shell 18 and is connected to a driving wheel 34. The cargo driving wheel 34 is connected to an adjacent driven wheel 32 by a transmission belt 33.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, one end of the bottom of the cargo support frame 10 is rotatably connected to the base 14, two first hinges 22 are symmetrically distributed and fixedly connected to the upper side of the cargo base 14, and two second hinges 23 are symmetrically distributed and fixedly connected to the lower side of the cargo support frame 10. A second electric push rod 24 is connected between the first hinge 22 and the second hinge 23 relative to each other, a battery compartment 15 is fixedly connected to the upper side of the cargo base 14, and one side of the cargo battery compartment 15 is electrically connected to the controller 16.

[0038] By providing the second electric push rod 24, the height of the support frame 10 can be adjusted according to actual conditions, so as to adapt to the height of various vehicles and improve the application range of the equipment.

[0039] In this embodiment, initially, the first side shell 17 is electrically connected to the second electric push rod 24, the motor 26 and the push block 20, and the push block 20 is in an extended state, so that each abutment plate 28 is located under the corresponding roller 27. When unloading is required, the worker moves the unloading rack to the rear end of the carriage and fixes the unloading rack. Then the worker controls the second electric push rod 24 through the first side shell 17 and then adjusts the height of the upper end of the support frame 10, so that the support frame 10 adapts to the height of the carriage and makes it stably connected to the carriage. Then the worker starts the motor 26 and drives all the rollers 27 to rotate through the driving wheel 34. Then the goods in the carriage are placed on the unloading rack one by one. The unloading rack moves the goods to the lower end, and the goods after moving to the lower end are collected and transferred by a dedicated person.

[0040] In the process of moving goods by the unloading rack, the goods may stop and not slide down. When the goods stop, since the diameter of the tooth edge of the ratchet sleeve 12 is slightly larger than the diameter of the ring 11, the soft and elastic ratchet on the ratchet sleeve 12 is squeezed and deformed by the goods under the rotation of the roller 27, thereby increasing the friction between the ratchet sleeve 12 and the goods, so that the roller 27 can push the goods down; when the goods slide by themselves, the goods press down the soft and elastic ratchet on the ratchet sleeve 12. At this time, the friction between the ratchet sleeve 12 and the goods is small, so that the goods can slide off the ring 11 quickly and efficiently, and the sliding is not affected by the rotation speed of the roller 27.

[0041] When all or part of the goods are stuck in the gap between the two rollers 27, the operator controls the first electric push rod 21 to retract through the first side shell 17, so that the push plate 25 slides to make the sliding pin 29 slide in the sliding groove 31, and then drives the swing arm 30 to swing and drive the support plate 28 to rotate, so that the support plate 28 pushes out the goods stuck in the gap, pushes the goods out of the gap and slides again, effectively solving the problem of goods getting stuck on the unloading rack and affecting work efficiency, and the support plate 28 is reset after pushing the goods.

[0042] When dangerous and fragile goods need to be unloaded, the abutment plate 28 is controlled to rotate and the ratchet plate 13 is kept flat with the inclined surface of the support frame 10. The soft and elastic ratchets on the ratchet plate 13 are in contact with the bottom side of the goods to provide friction, thereby slowing down the goods as they slide down, thereby protecting the goods. The method is simple and easy to control, flexible to operate, greatly saving working time and labor, and improving the efficiency of unloading.

[0043] Embodiment 2:

[0044] As a further embodiment, by replacing the second electric push rod 24 and the first electric push rod 21 in the first embodiment with a manual one-way hydraulic cylinder, when the second electric push rod 24 and the first electric push rod 21 need to be controlled, the function is realized through manual control by workers. This can greatly reduce the processing and use costs of the equipment while ensuring that the main functions and effects of the equipment remain unchanged, facilitate equipment maintenance, and improve the practicality of the equipment.
