Description

Technical Field

[0001] The present invention relates to the technical field of material handling, and in particular, to a lean material transfer trolley based on food industrial processing. Background Art

[0002] With the development of society and the improvement of people's living standards, the order volume of the livestock and poultry meat product industry has increased year by year with the social demand. At the current stage of the production process, most of the transportation of poultry meat products after slaughter and segmentation is manual transportation and handling, which wastes manpower, has limited transportation efficiency, and the safety during the handling process cannot be guaranteed. In order to implement lean production, improve production efficiency, optimize resource allocation, reduce the workload of employees, ensure product quality, and promote the sustainable development of enterprises, the demand for efficient and convenient transportation tools is increasing day by day. Lean portable material transfer trolleys play an important role in the short-distance transportation, in-store placement or temporary storage of poultry meat products due to their flexibility and portability. The trolley is designed simply and practically, which is convenient for workers to pull and transport poultry meat products. Its design focuses on operation convenience, reduces physical handling, and improves work efficiency. At the same time, this design also takes into account economic benefits and production strength, and is an ideal choice for the short-distance transportation of poultry meat products. Although the trolley can reduce physical handling and improve work efficiency when in use, there are still the following defects:

[0003] 1. In a logistics warehouse, in order to transport materials over a long distance, a transport vehicle is needed. When moving the materials on the trolley to the transport vehicle, in order to enable the trolley to smoothly enter the transport vehicle, the trolley may pass through a sloped passage. When the trolley is going uphill, since the trolley is full of materials, the gravity of the trolley is large. Under the action of the component force of gravity, the trolley has a tendency to move downward. When the slope is uneven or steep, the trolley cannot be well controlled, resulting in the trolley sliding downhill at a relatively fast speed. If there are people or vehicles on the ramp or at the bottom of the ramp, it is very likely to cause a collision, resulting in personal injury and vehicle damage, bringing potential safety hazards.

[0004] 2. When the existing trolley with universal wheels at the bottom is moving materials uphill, the trolley can move forward, backward and left and right under the action of the universal wheels. However, when the slope is uneven or it encounters small stones, the universal wheels on the trolley are prone to side rotation. The side rotation of the universal wheels makes the stability of the trolley worse, and during the uphill process, the trolley may roll over at any time. The rollover will not only cause a large loss of food, but may also injure the surrounding staff, triggering a serious safety accident. Moreover, when the universal wheels deviate to one side, some wheels will bear greater pressure and friction, accelerating the wear of these wheels and reducing the service life of the trolley. Summary of the Invention

[0005] In view of the problem that the existing carts in the prior art are prone to move downward when going uphill, causing the cart to shake or collide, resulting in damage to the food packaging, and the universal wheels at the bottom of the cart are prone to turn to one side when moving, causing the cart to tilt or even lie horizontally on the ramp, posing a safety hazard, a lean material transfer cart based on industrialized food processing is proposed.

[0021] Advantages of the present invention:

[0022] 1. Through the air intake assembly, gas enters the pushing assembly. Under the action of the pushing assembly, the anti-slope assembly is triggered, and the ratchet slides on the connecting shaft, causing the ratchet to engage with the end of the slide bar with an inclined surface. Under the action of the ratchet, the slide bar is blocked, and the front roller is limited, which can prevent the front roller from rotating clockwise. In this way, when the trolley is going uphill, under the action of the anti-slope assembly, the front roller cannot rotate backward, and further the trolley cannot move backward, avoiding the adverse effects brought by the trolley slipping backward and reducing potential safety hazards.

[0023] 2. When gas enters the cavity, under the action of the air holes, the gas enters the sleeve. As the gas in the sleeve gradually increases, the gas will push the first piston disk to slide on the connecting shaft. Through the connecting rod, the ratchet is driven to move towards the slide bar and engage with it, so that when the trolley is going uphill, the front roller is prevented from rotating backward, avoiding the trolley from slipping, enabling the trolley to smoothly cross the slope, preventing the trolley from being damaged, and avoiding injury caused by slipping.

[0024] 3. When gas enters the air cylinder, the piston rod moves downward, squeezing the pressing disk, driving the reciprocating assembly to rotate, aligning the universal wheel frame, and limiting the universal wheel frame. When the trolley is going uphill, the universal wheel frame is limited, preventing it from rotating to one side, avoiding the center of gravity of the trolley from shifting, and preventing the trolley from tilting, which may cause the food on the trolley to spill or topple, reducing the risk of injury to the staff.

[0040] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present invention in conjunction with the drawings in the specification.

[0041] Example 1, referring to Figures 1-12, which is the first embodiment of the present invention, provides a lean material transfer trolley based on food industrial processing, including a transfer vehicle frame 1, two rear universal wheels 11 symmetrically distributed and fixedly connected to one side of the bottom of the transfer vehicle frame 1, a sliding track 12 obliquely fixedly connected to the transfer vehicle frame 1, two hollow blocks 13 symmetrically distributed and fixedly connected to the other side of the bottom of the transfer vehicle frame 1, a universal wheel frame 14 rotatably connected to the bottom of the hollow blocks 13, and a front roller 15 rotatably connected to the universal wheel frame 14, and also includes an anti-slip unit installed on the transfer vehicle frame 1; the anti-slip unit includes an anti-slip component installed on the universal wheel frame 14, and a pushing component installed on the transfer vehicle frame 1, the anti-slip component includes an anti-slip component 2 installed on the universal wheel frame 14, a pushing component 3 installed on the universal wheel frame 14, and a telescopic component installed on the front roller 15. Part 4, and an air intake component 5 installed on the universal wheel frame 14; when the transfer vehicle frame 1 is going uphill, the gas in the air intake component 5 enters the pushing component 3, and the anti-slip component 2 is pushed by the pushing component 3 to brake the front roller 15 to prevent the front roller 15 from sliding backward and causing the car to slip. At the same time, the universal wheel frame 14 is corrected and limited by the pushing component to prevent the universal wheel frame 14 from turning sideways; the anti-slip component 2 includes two sleeves 21 symmetrically distributed and fixedly connected to the front roller 15, the two sleeves 21 are both rotatably connected to the universal wheel frame 14, a connecting shaft 22 fixedly connected to the universal wheel frame 14, the two sleeves 21 are both rotatably connected to the connecting shaft 22, a ratchet 23 slidably connected to the connecting shaft 22, a sliding rod 24 slidably connected to the front roller 15, an inclined surface is provided at the end of the sliding rod 24 away from the front roller 15, and is meshed with the ratchet 23.

[0042] Specifically, when the trolley is going uphill, the anti-slip component can prevent the trolley from sliding backward, and the pushing component can lock the universal wheels of the trolley to prevent the universal wheels from deflecting randomly, avoiding damage to food during transportation, improving the transfer progress, saving labor, enabling the trolley to move upward smoothly, cross the slope, and reducing the probability of potential safety hazards. By loading food into the supporting material box and placing the supporting material box on the sliding track 12, under the action of the sliding track 12, since the sliding track 12 is inclined, the supporting material box slides downward along the sliding track 12, pushing the transfer vehicle frame 1. Under the action of the rear universal wheel 11, the universal wheel frame 14, and the front roller 15, the transfer vehicle frame 1 moves on the ground. Through the air intake component 5, gas enters the pushing component 3. Under the action of the pushing component 3, the anti-slip component 2 is triggered, and the ratchet 23 slides on the connecting shaft 22, so that the ratchet 23 meshes with one end of the sliding rod 24 provided with an inclined surface. Push the trolley upward, causing the front roller 15 to rotate counterclockwise, driving the sliding rod 24 to rotate counterclockwise. Under the action of the telescopic component 4, the sliding rod 24 can be telescoped on the front roller 15. When the sliding rod 24 rotates counterclockwise, the sliding rod 24 slides on the ratchet 23. When the trolley is about to slip backward, the front roller 15 will rotate clockwise, driving the sliding rod 24 to rotate clockwise. At this time, under the action of the ratchet 23, the sliding rod 24 is blocked, and the front roller 15 is limited, preventing the front roller 15 from rotating clockwise. In this way, when the trolley is going uphill, under the action of the anti-slip component 2, the front roller 15 cannot rotate backward, and further the trolley cannot move backward, avoiding the adverse effects brought by the trolley sliding backward and preventing the trolley from sliding backward quickly and causing injury to personnel.

[0043] Refer to Figure 6 and Figure 7 , the pushing component 3 includes a first piston disk 31 that is limited and slidably connected to the connecting shaft 22. The first piston disk 31 is hermetically and slidably connected to one of the sleeves 21. A connecting rod 32 is fixedly connected between the first piston disk 31 and the ratchet 23. A cavity 33 is provided at one end of the connecting shaft 22, and the cavity 33 is communicated with the sleeve 21 through an air hole 34.

[0044] Specifically, when gas enters the cavity 33, under the action of the air holes 34, the gas enters the sleeve 21. As the gas in the sleeve 21 gradually increases, the gas will push the first piston disk 31 to slide on the connecting shaft 22. Through the connecting rod 32, the ratchet wheel 23 is driven to move towards the slide rod 24 and engage with the slide rod 24. When the trolley goes uphill, it can prevent the front roller 15 from rotating backward, avoid the trolley from slipping, and enable the trolley to smoothly cross the slope. When the gas flows out of the cavity 33, the gas in the sleeve 21 will decrease. Under the action of air pressure, the first piston disk 31 slides in the reverse direction to reset, driving the ratchet wheel 23 to move and separate from the slide rod 24, so that the trolley can move forward and backward on flat ground.

[0045] Referring to Figures 5-7 , the telescopic assembly 4 includes a movable cavity 41 opened on the front roller 15. One end of the slide rod 24 close to the front roller 15 is slidably connected to the movable cavity 41, and a telescopic spring 42 fixedly connected between the movable cavity 41 and the slide rod 24.

[0046] Specifically, under the action of the telescopic spring 42, the slide rod 24 can extend out of the movable cavity 41 and engage with the ratchet wheel 23. When the slide rod 24 rotates along the teeth of the ratchet wheel 23, the slide rod 24 will squeeze the telescopic spring 42. Under the action of the telescopic spring 42, the slide rod 24 continuously extends and retracts at one end of the movable cavity 41. At this time, the front roller 15 can rotate smoothly. When the slide rod 24 rotates against the teeth of the ratchet wheel 23, under the action of the ratchet wheel 23, the slide rod 24 cannot rotate, limiting the front roller 15 and preventing the trolley from slipping, avoiding injury to the staff and damage to the trolley.

[0047] Referring to Figure 8 , the air intake assembly 5 includes a ring 51 fixedly connected to the bottom of the hollow square 13. The ring 51 is rotatably connected to the universal wheel frame 14, a rotating plate 52 rotatably connected to the bottom of the ring 51, an air intake pipe 53 fixedly connected to the rotating plate 52. One end of the air intake pipe 53 away from the rotating plate 52 is fixedly connected to the connecting shaft 22 and communicates with the cavity 33.

[0048] Specifically, the ring 51 is a hollow structure. The gas in the ring 51 enters the air intake pipe 53 and then enters the cavity 33. Under the action of the rotating plate 52, the universal wheel frame 14 can rotate at the bottom of the ring 51.

[0049] Embodiment 2, referring to Figures 9-12, which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the pushing component includes a pushing assembly 6 installed on the frame 1 of the transport vehicle, an air vent assembly 7 installed in the pushing assembly 6, a delay assembly 8 installed in the pushing assembly 6, and a reciprocating assembly 9 installed on the frame 1 of the transport vehicle; the pushing assembly 6 includes an L-shaped plate 61 fixedly connected to the frame 1 of the transport vehicle, a cylinder 62 fixedly connected to the L-shaped plate 61, a piston rod 63 slidably connected to the cylinder 62, the piston rod 63 passing through the L-shaped plate 61, and a pushing disk 64 fixedly connected to the piston rod 63.

[0050] Specifically, the L-shaped plate 61 fixedly installs the cylinder 62. Gas enters the cylinder 62, causing the piston rod 63 to move downward, squeezing the pushing disk 64, driving the reciprocating assembly 9 to rotate, straightening the universal wheel frame 14, and limiting the universal wheel frame 14. When the trolley is going uphill, the universal wheel frame 14 is limited, so that the universal wheel frame 14 will not rotate to one side, avoiding the center of gravity of the trolley from shifting, causing the trolley to tilt, resulting in the food on the trolley spilling or toppling, improving the safety of using the trolley.

[0051] Refer to Figure 10 , the air vent assembly 7 includes a second piston disk 71 slidably connected in the cylinder 62, the piston rod 63 is fixedly connected to the second piston disk 71, an L-shaped hole 72 opened on one side of the second piston disk 71, an L-shaped pipe 73 fixedly connected to one side of the cylinder 62, and the end of the L-shaped pipe 73 away from the cylinder 62 is fixedly connected to the ring 51 and communicates with the inside of the ring 51.

[0052] Specifically, gas enters the cylinder 62, pushes the second piston disk 71 downward, drives the piston rod 63 to move downward. At this time, under the action of the inner wall of the cylinder 62, one end of the L-shaped hole 72 is sealed, so that the gas in the cylinder 62 will not pass through the L-shaped hole 72. As the second piston disk 71 continuously moves downward in the cylinder 62, when the second piston disk 71 moves to the bottom of the cylinder 62, one end of the L-shaped hole 72 communicates with the L-shaped pipe 73. At this time, the second piston disk 71 will no longer move downward. The gas in the cylinder 62 will enter the L-shaped pipe 73 from the L-shaped hole 72, and then enter the ring 51. When the trolley is going uphill, it can not only straighten and limit the universal wheel frame 14, but also prevent the front roller 15 from moving backward, avoiding the potential safety hazards brought by landslides.

[0053] Refer to Figure 10 and Figure 11 , the delay assembly 8 includes a cavity 81 opened on the cylinder 62, a protrusion 82 slidably connected to one end of the cavity 81, a delay spring 83 fixedly connected between the inner wall of the cavity 81 and the protrusion 82, a groove 84 opened on the second piston disk 71, and the protrusion 82 is snap-fitted in the groove 84.

[0054] Specifically, the gas enters the gas cylinder 62, causing the second piston disc 71 to move downward. When the second piston disc 71 moves to the bottom of the gas cylinder 62, the second piston disc 71 squeezes the protrusion 82, squeezes the delay spring 83, and causes the protrusion 82 to move into the cavity 81. When the protrusion 82 is directly opposite to the groove 84, the delay spring 83 will be reset, causing the protrusion 82 to move out of the cavity 81 and engage with the groove 84, which limits the second piston disc 71. At this time, the L-shaped hole 72 is connected with the L-shaped tube 73. When the cart moves from the slope to the plane, the gas at the top of the gas cylinder 62 will gradually decrease. Under the limit of the engagement between the protrusion 82 and the groove 84, the second piston disc 71 will not move upward at this time. At this time, the L-shaped hole 72 is still connected with the L-shaped tube 73, and the gas in the L-shaped tube 73 will enter the gas cylinder 62 from the L-shaped hole 72. When the gas in the L-shaped tube 73 no longer enters the gas cylinder 62, the second piston disc 71 is pushed upward by the gas pressure, so that the protrusion 82 is separated from the inner side of the groove 84, and the second piston disc 71 is reset.

[0055] Reference Figure 12 The reciprocating assembly 9 includes a rotating cylinder 91 rotatably connected to the hollow block 13, the rotating cylinder 91 is fixedly connected to the universal wheel frame 14, a column 92 fixedly connected to the rotating cylinder 91, an L-shaped rod 93 slidably connected to the rotating cylinder 91, a ball 94 arranged at one end of the L-shaped rod 93, the other end of the L-shaped rod 93 passes through the hollow block 13 and abuts against the push plate 64, a reciprocating spiral groove 95 is opened on the column 92, and the ball 94 is rollingly connected to the reciprocating spiral groove 95.

[0056] Specifically, when the cart is moving, the universal wheel frame 14 rotates with the movement of the cart, and drives the column 92 to rotate through the rotating cylinder 91. Under the action of the reciprocating spiral groove 95, the ball 94 rolls in the reciprocating spiral groove 95, driving the L-shaped rod 93 to move up and down. When the cart is about to go uphill, the push plate 64 moves downward, pushing the L-shaped rod 93 to move downward, driving the ball 94 to move downward in the reciprocating spiral groove 95, causing the column 92 to rotate, and driving the universal wheel frame 14 to rotate. When the ball 94 moves to the bottom of the reciprocating spiral groove 95, the universal wheel frame 14 is just straightened, and the push plate 64 is still pressed on the L-shaped rod 93, limiting the column 92, and then limiting the universal wheel frame 14, so that the universal wheel frame 14 cannot rotate. The rest of the structure is the same as that of Example 1.

[0057] Example 3, reference Figure 13, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that it further includes an air storage component 10. The air storage component 10 includes two rubber air storage sleeves 101 symmetrically distributed and fixedly connected to the transfer vehicle frame 1, a support spring 102 fixedly connected inside the rubber air storage sleeve 101, an elbow pipe 103 fixedly connected to the transfer vehicle frame 1, one end of the elbow pipe 103 is fixedly connected to the rubber air storage sleeve 101, a straight pipe 104 fixedly connected to the other end of the elbow pipe 103, and the end of the straight pipe 104 away from the elbow pipe 103 is fixedly connected to the air cylinder 62.

[0058] Specifically, when pushing the cart on flat ground, under the action of the support spring 102, the rubber air storage sleeve 101 will not be squeezed, the gas in the rubber air storage sleeve 101 will not enter the elbow pipe 103, the anti-slope unit will not be triggered, and the cart can walk normally. When encountering a slope, due to the component of gravity, the cart has a tendency to move downward. At this time, when the cart needs to move forward, the required pushing force will increase. At this time, the support spring 102 will be compressed, the rubber air storage sleeve 101 will be squeezed, and the gas in the rubber air storage sleeve 101 will enter the elbow pipe 103, triggering the anti-slope unit. This makes the cart not only unable to slide backward, but also the universal wheels of the cart will not rotate to one side, causing the cart to tilt, which not only easily injures the staff, but also easily causes the cart to be deformed and damaged.

[0059] Refer to Figure 2 , it further includes a material blocking component 16. The material blocking component 16 includes a plurality of material blocking plates 161 symmetrically distributed and rotatably connected to the transfer vehicle frame 1, a plurality of slots 162 symmetrically distributed on the transfer vehicle frame 1, a bolt 163 slidably connected to the material blocking plate 161, and the bolt 163 is inserted into one of the corresponding slots 162.

[0060] Specifically, before loading the cart, rotate the material blocking plate 161 so that the material blocking plate 161 is vertically upward, insert the bolt 163 into the material blocking plate 161, and make the bolt 163 inserted into the slot 162. Under the action of the material blocking plate 161, the supporting material box on the cart is blocked to prevent the supporting material box from sliding off the sliding track 12. When the cart reaches the unloading point, pull out the bolt 163 from the material blocking plate 161. The material blocking plate 161 will lose its limiting function and rotate downward on the transfer vehicle frame 1 to release the limit on the supporting material box. Under the action of the sliding track 12, the supporting material box slides from the transfer vehicle frame 1 to the placing rack to complete the material transfer. The remaining structures are the same as those in Embodiment 2.

[0061] Combining Embodiments 1-3, the working principle of the present invention is as follows: When the trolley encounters an uphill slope, the pushing force will increase. Under the action of the air storage assembly 10, the gas in the elbow pipe 103 enters the air cylinder 62. Under the action of the pushing assembly 6, the reciprocating assembly 9 is pushed, so that the L-shaped rod 93 and the ball 94 move to the bottom of the reciprocating spiral groove 95 to limit the upright column 92, so that the universal wheel frame 14 is straightened and limited. The gas in the air cylinder 62 enters the ring 51 through the L-shaped pipe 73, enters the cavity 33 through the air inlet pipe 53, enters the sleeve 21 through the air hole 34, pushes the first piston disk 31 to move, drives the ratchet wheel 23 to move towards the sliding rod 24, and meshes with the sliding rod 24. This not only makes it difficult for the universal wheels of the trolley to rotate to one side, but also when the trolley slides backward, under the action of the ratchet wheel 23 and the sliding rod 24, the front rollers 15 are limited to prevent the trolley from sliding, improving the safety of the trolley during use.
