Description

Technical Field

[0001] The utility model relates to the technical field of logistics sorting, in particular to a flip-plate trolley with a buffering function. Background Art

[0002] In recent years, with the development of domestic e-commerce, the sorting volume of express parcels, shoes, clothing, books and other items has increased exponentially. Sorting equipment has emerged as equipment for transporting and sorting items. The flip structure on the sorting trolley plays an important role in the entire sorting process. The flip is used to guide the flow of items, prevent items from falling during transportation, or serve as a mark to distinguish different sorting paths. The trolley signal flip mechanism straightens when receiving a signal. If the trolley probe detects an obstacle, it will brake and stop immediately. If the brake is slow and hits the flip, the flip has a buffering function and will not damage the trolley and the flip mechanism.

[0003] Chinese invention patent publication number: CN 110102484 B, discloses: a flip-plate trolley and sorting equipment, which achieve synchronous movement under the action of a first connecting rod assembly and a second connecting rod assembly. When the first sorting tray and the second sorting tray are combined and contacted, baffles can be provided at the edges not used to contact the edges of the other sorting tray to prevent items from sliding when not in transport. However, the flip-plate trolley and sorting equipment are not designed with a brake structure during use. When braking, if the brake is slow, the signal trolley can easily hit the flip plate, causing damage to the trolley and the flip plate mechanism, thus affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flip-plate trolley with a buffering function, which can effectively solve the problem in the prior art that no braking structure is designed during use. When braking, when the brake is slow, it is easy for the signal trolley to hit the flip plate, thereby causing damage to the trolley and the flip plate mechanism, thereby affecting normal use.

[0005] The utility model discloses a technical scheme adopted by the utility model is: a turnplate trolley with buffering function, including the trolley track and the trolley body of trolley track outer surface sliding connection, the trolley track inner surface fixed mounting has the lid box and the base box, the base box inner surface rotatory mounting has the pivot, the pivot outer surface fixed mounting has the half gear, the half gear outer surface fixed mounting has the limit bushing, the limit bushing inboard fixed mounting has the clamping spring, the one end fixed mounting of lid box and base box has the limit component, the trolley body inner surface rotatory mounting has the pulley, the trolley body outer surface fixed mounting has the trolley probe, the one end fixed mounting of trolley body near trolley probe has the limit frame and the blocking frame, the limit frame inner surface sliding connection has the buffer plate, the one end fixed mounting of buffer plate near trolley body has the buffer component, the trolley track outer surface is provided with the rail changing mechanism.

[0006] Preferably, the limit component includes a limit plate, a limit groove adapted to the rack is formed in the outer surface of the limit plate, a fixed plate is fixedly installed at one end of the limit plate close to the rack, a support plate is fixedly installed on the outer surface of the fixed plate, and the other end of the support plate is fixedly installed with the limit plate.

[0007] Through the above technical scheme, when the clamping spring deforms, the force of the connecting end can act on the outer surface of the fixed plate, which can avoid the deformation of the clamping spring when driving the turnplate, and improve the anti-deformation ability.

[0008] Preferably, the other end of the clamping spring away from the limit bushing is fixedly installed with a connecting end, and the other end of the connecting end is in contact with the limit component.

[0009] Through the above technical scheme, during the operation of the trolley, the clamping spring keeps in contact with the limit component through the connecting end. When the trolley probe detects an obstacle, the brake stops immediately. If the brake is dull, the turnplate is hit. Through the cooperation of the clamping spring and the connecting end, the trolley and the turnplate mechanism are not damaged, the trolley is stable in the mechanical control of separating and merging, and the defects of the machinery are compensated.

[0010] Preferably, the buffer component includes a fixed seat and a limit seat, a sliding rod is fixedly installed at the other end of the fixed seat, a sliding sleeve is slidingly connected to the outer surface of the sliding rod, a spring is fixedly installed at the other end of the fixed seat close to the sliding rod, the other end of the spring is fixedly installed with the limit seat, and a fixed sleeve is fixedly installed on the outer surface of the limit seat.

[0011] Through the above technical solution, when the buffer plate is impacted by external force, the external force is transmitted to the sliding rod through the fixed seat. The sliding rod slides in the sliding sleeve and compresses the spring at the same time. The spring absorbs and buffers the impact force, which can effectively convert the impact energy into the elastic potential energy of the spring, reducing the direct impact of the external force on the trolley body and other components. The sliding connection between the sliding rod and the sliding sleeve ensures the smoothness of the buffering process, while the fixed sleeve and the limit seat help to maintain the stability of the spring, making the buffering effect more reliable.

[0012] Preferably, the buffer assembly is provided with four identical ones, the fixing seat and the buffer plate are fixedly installed, and the other end of the limiting seat and the trolley body are fixedly installed.

[0013] Through the above technical solution, the four buffer components are evenly distributed between the buffer plate and the trolley body. When the buffer plate is impacted in different directions, each buffer component works simultaneously. The fixed connection between the fixed seat and the buffer plate, and the limit seat and the trolley body ensures that the buffer force can be effectively transmitted and dispersed, thereby improving the efficiency of the entire buffer system, reducing damage caused by excessive local force, and further improving its buffering effect.

[0014] Preferably, a protective frame, a limit block and a positioning bolt are fixedly installed on one end of the buffer plate away from the trolley body. The protective frame is located on the front side of the trolley probe, and the positioning bolt passes through the protective frame and extends to the inside of the buffer plate.

[0015] Through the above technical solution, the protective frame can effectively prevent external objects from directly colliding with the trolley probe, avoid damage to the probe, and ensure the normal detection function of the trolley. The limit block enhances the structural stability of the buffer plate so that it will not be excessively displaced and lose its buffering effect when impacted.

[0016] Preferably, the outer surface of the half gear is meshed with a rack, the other end of the rack away from the half gear is fixedly installed with an electric push rod, the inside of the base box is fixedly installed with a sensor, and the outer surface of the half gear is fixedly installed with a flap.

[0017] Through the above technical solution, the electric push rod starts to push the rack to move, the rack engages with the half gear to drive the half gear to rotate, and the rotation of the half gear drives the flap to flip. At the same time, the sensor monitors the position of the flap in real time. The transmission method of the electric push rod, rack and half gear can accurately control the flip angle and position of the flap to meet different signal display requirements.

[0018] Compared with the prior art, the present invention provides a flip car with a buffering function, which has the following beneficial effects:

[0019] 1. The flip-plate trolley with a buffering function keeps the retaining spring in contact with the limit assembly through the connecting end during the operation of the trolley. When the trolley probe detects an obstacle, it will brake and stop immediately. If the brake is slow and hits the flip plate, the cooperation between the retaining spring and the connecting end can make it have a buffering function without damaging the trolley and the flip plate mechanism. It is used to stabilize the mechanical control of the trolley lane separation and merging, and to compensate for mechanical defects.

[0020] 2. This flip-up trolley with a buffering function, when the buffer plate is impacted by external force, the external force is transmitted to the sliding rod through the fixed seat. The sliding rod slides in the sliding sleeve and compresses the spring at the same time. The spring absorbs and buffers the impact force, which can effectively convert the impact energy into the elastic potential energy of the spring, reducing the direct impact of the external force on the trolley body and other components. The sliding connection between the sliding rod and the sliding sleeve ensures the smoothness of the buffering process, while the fixed sleeve and the limit seat help to maintain the stability of the spring, making the buffering effect more reliable;

[0021] 3. The protective frame of the flip trolley with buffering function can effectively prevent external objects from directly colliding with the trolley probe, avoid damage to the probe, and ensure the normal detection function of the trolley. The limit block enhances the structural stability of the buffer plate, so that it will not be excessively displaced and lose the buffering effect when it is impacted.
