[0032] The pushing mechanism 300 includes a pushing component 301, which is arranged on the top of the support plate 101, and a clamping component 302 is arranged on both the front and rear sides of the support plate 101; the pushing component 301 includes a pushing groove 301a, which is opened on the top of the support plate 101, and a first pushing rod 301b is arranged on the surface of the pushing groove 301a, and a pushing plate 301c is arranged on the left side of the first pushing rod 301b; the clamping component 302 includes a clamping groove 302a, which is opened on the top of the support plate 104, and a support block 302b is fixedly installed on the bottom of the support plate 104, and the support block 302b is Fixed columns 302c are fixedly installed on both the left and right sides, and the surfaces of the fixed columns 302c are rotatably connected to the rotating rods 302d, and the opposite sides of the rotating rods 302d and the fixed columns 302c are provided with torsion springs 302e, and two clamping blocks 302f are fixedly installed on the front and rear sides of the support plate 104, and the opposite sides of the two clamping blocks 302f are rotatably connected to the connecting rods 302g, and the surface of the connecting rods 302g is fixedly installed with clamping plates 302h, and the bottom of the clamping plates 302h contacts the top of the rotating rod 302d, and the opposite sides of the rotating rod 302d are provided with connecting pieces 302i, and the rear side of the connecting pieces 302i is provided with pulleys 302j.

[0034] Furthermore, the staff first places the goods on the top of the pallet 104, and the goods will squeeze the pulley 302j. After being squeezed, the pulley 302j will move downward and drive the rotating rod 302d to flip. During the flipping of the rotating rod 302d, an squeezing force can be applied to the clamping plate 302h, so that the clamping plate 302h can be flipped using the connecting rod 302g to limit the clamping of the goods. Then, the staff uses the controller to start the lifting component 200. When the lifting component 200 is running, it can drive the pallet 104 to move upward on the surface of the screw 205. When the pallet 104 moves to a certain height, the staff uses the controller to start the first push rod 301b, so that the goods can be pushed into the collection box 105.

[0035] Reference Figure 4 and 5 , which is a second embodiment of the present invention, provides a positioning mechanism 400 to achieve greater stability of the cargo during the lifting process.

[0036] The positioning mechanism 400 includes a first positioning component 401 and a second positioning component 402. The first positioning component 401 and the second positioning component 402 are respectively arranged on the outer side of the support plate 101 and the outer side of the universal wheel 102. The first positioning component 401 includes a positioning plate 401a. The upper and lower sides of the positioning plate 401a are penetrated by a lifting plate 401b. The bottom of the lifting plate 401b is fixedly installed with a connecting plate 401c. The outer side of the lifting plate 401b is fixedly installed with an annular rod 401d. The top of the annular rod 401d is fixedly installed with a vertical rod 401e. The top of the vertical rod 401e penetrates the top of the positioning plate 401a. The surface of the vertical rod 401e is sleeved with a first spring 401f. The upper and lower sides of the first spring 401f are connected to the vertical rod 401e. The bottom and the top of the positioning plate 401a are fixedly installed; the second positioning component 402 includes an arc rod 402a, the arc rod 402a is arranged on the front side of the support plate 104, the bottom of the arc rod 402a is in contact with an inclined plate 402b, and the left and right sides of the inclined plate 402b are penetrated by a cross bar 402c, the rear side of the cross bar 402c is fixedly installed with the front side of the universal wheel 102, and a positioning rod 402d is fixedly installed on the left side of the inclined plate 402b, and the surface of the positioning rod 402d is sleeved with a second spring 402f, and the front and rear sides of the second spring 402f are respectively fixedly installed on the front side of the universal wheel 102 and the rear side of the inclined plate 402b, and the surface of the universal wheel 102 is provided with a plurality of positioning grooves 402e, and the positioning rod 402d is used in conjunction with the positioning groove 402e.

[0037] Specifically, when the goods are placed on the top of the bottom placement plate 501a, the first positioning component 401 can be triggered to support the device. When the goods need to be lifted, the second positioning component 402 can be triggered to support the device, so that the goods are more stable during the lifting process.

[0038] Furthermore, when the goods are placed on the top of the bottom placement plate 501a, the lifting plate 401b can be squeezed. After the lifting plate 401b is subjected to the squeezing force, the connecting plate 401c can be squeezed downward to make the connecting plate 401c fall to the ground and lift up the device. Since the goods are in a state of constantly squeezing the lifting plate 401b, the lifting plate 401b can be released from squeezing when the goods are retracted after placement. When the height of the goods needs to be increased for placement, the height of the support plate 104 can be increased while driving the arc rod 402a to move upward. In the process of the arc rod 402a moving upward, the squeezing state of the inclined plate 402b can be released, and then the inclined plate 402b will be subjected to the pulling force of the second spring 401f to drive the positioning rod 402d to the inside of the positioning groove 402e, thereby locking its universal wheel 102.

[0039] It should be noted that the second spring 401f is in a pulled state.

There are several and evenly distributed on the top of the placement plate 501a, two limiting rods 502b are fixedly installed on the surface of the extrusion groove 502a, and the surfaces of the two limiting rods 502b are slidably connected with the extrusion rods 502c, and the surfaces of the two limiting rods 502b are sleeved with third springs 502f, and the left and right sides of the third springs 502f are fixedly installed on the side opposite to the extrusion groove 502a and the extrusion rod 502c, and the extrusion plate 502d is fixedly installed on the side opposite to the extrusion rod 502c, and the front side of the extrusion rod 502c is provided with an extrusion shaft 502e; the push-out component 503 includes a moving rod 503a, and an inclined rod 503b is fixedly installed on the top of the moving rod 503a. The bottom of 03b is in contact with the surface of the extrusion shaft 502e, the left and right sides of the moving rod 503a are penetrated to the left and right sides of the extrusion groove 502a, the top of the moving rod 503a is fixedly installed with a plurality of push-out blocks 503c, the surfaces of the plurality of push-out blocks 503c are in contact with the surface of the sliding column 501e, the interior of the placement plate 501a is provided with a plurality of push-out grooves 503d, the rear side of the moving rod 503a is fixedly installed with a plurality of push-out rods 503e, the surfaces of the plurality of push-out rods 503e are in contact with the surfaces of the plurality of push-out grooves 503d, the tops of the plurality of push-out rods 503e are fixedly installed with push-out columns 503f, and the tops of the push-out columns 503f are It penetrates to the top of the placement plate 501a; the sensing component 601 includes a pressure sensor 601a, which is arranged on the right side of the extrusion plate 502d, and the inner wall of the collection box 105 is fixedly installed with a plurality of second push rods 601b, and the pushing ends of the plurality of second push rods 601b are fixedly installed with a fixed plate 601c; the auxiliary extrusion component 602 includes a matching rod 602a, and the surface of the matching rod 602a is rotatably connected with a travel rod 602b, and the upper and lower sides of the travel rod 602b are provided with travel grooves 602c, and the bottom of the fixed plate 601c is fixedly installed with a travel column 602d, and the surface of the travel column 602d is in contact with the inner wall of the travel groove 602c.

[0042] Specifically, when the goods are pushed to the top of the placement plate 501a, the feeding assembly 501 can be used to facilitate the movement of the goods to the innermost part of the placement plate 501a.

[0043] Furthermore, when the goods are pushed to the top of the placement plate 501a, since the initial state of the roller 501b is right high and left low, the goods can slide to the leftmost side on the surface of the roller 501b. When the goods slide to the leftmost side, the squeezing plate 502d will be squeezed. After the squeezing plate 502d is squeezed, the squeezing rod 502c can be used to drive the squeezing shaft 502e to squeeze the surface of the inclined rod 503b. After the inclined rod 503b is squeezed, the moving rod 503a can be driven to move upward on the surface of the squeezing groove 502a, thereby driving the push-out column 503f to move to the top of the placement plate 501a to increase the friction force on the bottom of the goods. When the goods cause squeezing force on the squeezing plate 502d, the pressure sensor 601a is sensed and the controller is used to start the second pushing rod 601b. The operation of the second pushing rod 601b can clamp the goods. When the goods need to be taken out, first pull the goods outward a little to release the sensing end of the pressure sensor 601a, and the second push rod 601b releases the clamping of the goods and retracts at the same time. During the retraction of the second push rod 601b, the travel column 602d can be driven to move on the surface of the travel groove 602c and squeeze the travel groove 602c, so that the travel groove 602c is squeezed and the squeezing force is transmitted to the travel rod 602b, and the squeezing force received by the travel rod 602b is used to drive the matching rod 602a to move, so that the matching rod 602a drives the moving rod 503a to move on the surface of the squeezing groove 502a, and the movement of the moving rod 503a can drive the resisting block 503c to squeeze the sliding column 501e, so that the rollers 501b at the respective driving positions are raised to different heights, so as to achieve a state of left high and right low for easy removal.

[0044] It should be noted that the shapes of the push-out blocks 503 c are all trapezoidal, and the angles thereof are 100, 120, 140 and 160 (from left to right).

[0045] Reference Figures 1 to 8 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a lifting device for cargo transportation.

[0046] When using the device, the staff first places the goods on the top of the pallet 104, and the goods will squeeze the pulley 302j. After being squeezed, the pulley 302j will move downward and drive the rotating rod 302d to flip. During the flipping process of the rotating rod 302d, it can cause squeezing force on the clamping plate 302h, so that the clamping plate 302h can be flipped by the connecting rod 302g to limit the clamping of the goods. Then, the staff uses the controller to start the lifting component 200. When the lifting component 200 is running, it can drive the pallet 104 to move upward on the surface of the screw 205. When the pallet 104 moves to a certain height, the staff uses the controller to start the first push rod 301b to push the goods. When it is necessary to place goods on the top of the primary placement plate 501a, the goods can be pushed by the first pushing rod 301b to squeeze the lifting plate 401b. After the lifting plate 401b is squeezed, it can squeeze the connecting plate 401c downward, so that the connecting plate 401c falls to the ground and lifts up the device. Since the goods are in a state of constantly squeezing the lifting plate 401b, the lifting plate 401b is released from squeezing when the goods are retracted after placement. When it is necessary to raise the height of the goods for placement, the height of the supporting plate 104 is raised, and the arc rod 402a can be driven to move upward at the same time. In the process of the arc rod 402a moving upward, the squeezing state of the inclined plate 402b can be released, and then the inclined plate 402b will be pulled by the third spring 502f to drive the positioning rod 402d to the inside of the positioning groove 402e, and its universal wheel 102 is locked. When it is necessary to place goods on the top of the higher-level placement plate 501a, the first pushing rod 301b is pushed. Since the initial state of the roller 501b is right high and left low, the goods can slide to the leftmost side on the surface of the roller 501b. When the goods slide to the leftmost side, the squeezing plate 502d is squeezed. After the squeezing plate 502d is squeezed, the squeezing rod 502c can be used to drive the squeezing shaft 502e to squeeze the surface of the inclined rod 503b. After the inclined rod 503b is squeezed, the moving rod 503a can be driven to move upward on the surface of the squeezing groove 502a, thereby driving the push-out column 503f to move to the top of the placement plate 501a to increase the friction force on the bottom of the goods. When the goods cause squeezing force on the squeezing plate 502d, the pressure sensor 601a is sensed and the second pushing rod 601b is started by the controller. Through the operation of the second pushing rod 601b, The goods are clamped; when the goods need to be taken out, the goods are first pulled outward a little to release the sensing end of the pressure sensor 601a, and the second push rod 601b releases the clamping of the goods and retracts at the same time. During the retraction of the second push rod 601b, the travel column 602d can be driven to move on the surface of the travel groove 602c and squeeze the travel groove 602c at the same time, so that the travel groove 602c is squeezed and the squeezing force is transmitted to the travel rod 602b, and the squeezing force received by the travel rod 602b is used to drive the matching rod 602a to move, so that the matching rod 602a drives the moving rod 503a to move on the surface of the squeezing groove 502a, and the movement of the moving rod 503a can drive the anti-block 503c to squeeze the sliding column 501e, so that the rollers 501b at the respective driving positions are raised to different heights, so as to achieve a state of left high and right low for easy removal.

[0047] In summary: the positioning mechanism 400 can be provided to increase the stability of the device when the goods are lifted, and the feeding mechanism 500 and the taking mechanism 600 can be provided to facilitate the placement and removal of the goods.
