[0003] Limited by the volume of container, the higher the loading density, the greater the carrying capacity, and the more stable the goods transportation process, which makes the stacking gap between goods stacks very small after loading, for example, the loading of barrel goods, the gap between two stacks in the same row is only 3mm, therefore, in the case that the same side of the carriage in the same row has been filled with goods, the handling trolley body needs to be adjusted to the coaxial direction of the fork frame and the container, so as to ensure that the fork frame can accurately load the goods into the empty space for stacking, especially when stacking the last few rows of goods, the space left for the fork frame to enter the container is very narrow.
[0004] However, the existing handling trolley generally only has obstacle avoidance walking function, and the steering of the trolley body is mainly realized by differential rotation between the front wheels on both sides, so it cannot adjust the trolley body in time to ensure that the handling trolley is always coaxial with the carriage during loading, and as the loading proceeds, the lifting platform and the carriage are prone to relative displacement in the transverse direction, which causes the trolley body to deviate when entering the carriage, and further causes the fork frame to be unable to extend into the empty space in the carriage for stacking when loading, which requires constant adjustment to the trolley body to ensure that the trolley body is coaxial with the carriage, resulting in low loading efficiency.

[0019] The beneficial effects of the present application are as follows:
[0020] 1. By adding clamping pieces, after the platform is coaxial with the corresponding carriage and the front end is connected with the rear end of the carriage, the two clamping pieces can be driven by the clamping drive assembly to move towards each other to clamp and fix the carriage, so that the platform and the carriage always remain coaxial during loading. On this basis, through the cooperation between the guide piece and the guide wheel group, the carrier body of the carrier body always remains coaxial with the carriage during the process of walking on the platform into the carriage, and the feeding mechanism can accurately place the goods on the loading mechanism, and through the cooperation between the front and rear rotating walking wheel group and the left and right swinging swing wheel group and the distance sensing device, when the carrier body of the carrier body is skewed by the influence of the concave-convex of the carriage floor, the left and right swinging of the swing wheel group can quickly adjust back to normal, thereby ensuring that the carrier body is always coaxial with the carriage during loading, so that in the case that the same side of the carriage has been filled with goods, the next batch of goods can be loaded into the empty space after the carrier body is moved horizontally, and when the last row of goods closest to the carriage door is loaded, the carrier body of the carrier body can be limited by the guide piece and the guide group to ensure that it is opposite to the carriage, and only the loading mechanism is horizontally moved to load the goods, greatly improving the stability and accuracy of the goods loading, improving the efficiency and density of the loading, and avoiding the situation that the carrier body is skewed and the loading mechanism is damaged. The goods in the box or the side wall of the container are impacted.
[0021] 2. By placing the rear guide wheel group and the front guide wheel group behind the swing wheel group and the walking wheel group respectively, during the process of the carrier body retreating from the carriage to the platform, the swing wheel group is accurately moved to the two sides of the guide piece through the limiting cooperation of the rear guide wheel group and the guide piece, and the two walking wheel groups are accurately moved to the two sides of the guide piece through the limiting cooperation of the front guide wheel group and the guide piece, thereby improving the guiding stability and accuracy of the guide wheel group.
[0022] 3. The guide piece is divided into a plurality of guide blocks and a positioning block, so that the guide piece can be installed and used on the existing lifting platform, greatly reducing the additional cost of the guide piece, and through the positioning and guiding effect of the positioning block, the rear guide wheel can smoothly roll to the left and right sides of the guide blocks after contacting, avoiding the situation of guide jamming, and improving the practicality of the guide piece.
[0023] 4. By adding a guide structure, the two front guide wheels and the two rear guide wheels can be elastically rolled and clamped on the left and right sides of the guide blocks, and through the linkage and limiting of the guide rod, guide block and two connecting rods, the relative displacement between the two front guide wheels and the two rear guide wheels is the same, so that the front guide wheel group and the rear guide wheel group are always coaxial with the carriage when they are rolled and clamped on both sides of the guide block. Under the premise of ensuring the guiding accuracy of the front guide wheel group and the rear guide wheel group, the rolling and clamping spacing between the front guide wheels and the rear guide wheels is adjusted, improving the adaptability of the guide wheel group.
[0024] 5、Through several sets of rod, the opposite movement or opposite movement of the two clamping pieces is stably guided, through the other end of the clamping oil cylinder movably penetrating the mounting seat, and through the cooperation between the fixedly arranged sliding sleeve and the sleeve rod slidingly penetrating the sliding sleeve, and the radial abutment between the several limiting rods and the mounting seat, the stress of the two clamping pieces after being clamped towards each other can be dispersed after being conducted to the mounting seat through the radial abutment between the sleeve rod and the sliding sleeve, so as to assist in dispersing the stress of the telescopic end of the clamping oil cylinder, improve the stability of the clamping of the clamping piece and the service life of the clamping oil cylinder; at the same time, the additional connection part is used for connecting with the several sleeve rods and a clamping oil cylinder arranged side by side in front and back, the connection point of the clamping piece is increased, when the two connection parts have a movement trend towards each other and backward under the opposite pressure of the two clamping blocks clamping the carriage towards each other, the several sleeve rods can assist the clamping oil cylinder to support the connection part from front to back through the radial abutment with the sliding sleeve and the radial abutment between the several limiting rods and the mounting seat, so as to further improve the clamping stability of the clamping piece.
[0025] 6、In the case that the handling trolley body enters the platform from front to back and the front part of the handling trolley body is inclined, the rolling abutment limiting between the front guide wheel set and the guide piece makes the walking wheel set walk through several rolling balls and then swing to one side, and then the front end of the handling trolley body is swung and adjusted, and the several rolling balls are compressed and reset by the elastic member after the walking wheel set passes. Thus, the rolling guidance of the front part of the handling trolley body is realized through the setting of the several universal adjusting devices, so that the walking wheel set does not generate friction with the platform, but generates rolling friction with the several rolling balls, avoiding the forced adjustment of the front part of the handling trolley body through the rolling abutment cooperation between the guide wheel set and the guide piece, which may cause damage to the guide wheel set or the walking wheel set, and may cause the handling trolley body to be unable to be coaxially arranged with the carriage on the platform, improving the stability of the handling trolley body when reversing from front to back to the platform and cooperating with the guide piece, ensuring that the cooperation between the guide wheel set and the guide piece can be stably and smoothly realized, ensuring that the handling trolley body can be coaxially arranged with the carriage on the platform during the next loading, and improving the adaptability of the platform to the coaxial guidance of the handling trolley body.
[0026] 7、By adding the lifting guide rail and several steering wheels, in the case of the trolley body entering the platform from front to back and the front part of the trolley body being slightly skewed, the two steering wheels are positioned to the left and right sides of the several guide blocks and roll on the two lifting rails to lift the rear end of the trolley body. The several guide wheels are rolled against the left and right sides of the guide, the several steering wheels are limited in steering by the left and right guide wheels and guided by the guide surface to roll up to the top of the several guide blocks, so as to lift the front end of the trolley body and make the walking wheel group suspended. The front end of the trolley body is controlled by the rolling abutment between the front guide wheel group and the positioning block, and the steering wheel walks on the positioning block, which is not hindered by the suspended walking wheel group, thereby avoiding the damage of the guide wheel group or the damage of the walking wheel group and the platform top caused by forcibly aligning the front part of the trolley body through the rolling abutment of the guide wheel group and the guide, and the trolley body cannot be coaxially arranged with the carriage on the platform due to the deviation of the guide wheel group or the walking deviation of the walking wheel group, thereby improving the stability of the trolley body when reversing from front to back on the platform and cooperating with the guide, ensuring the stable and smooth cooperation between the guide wheel group and the guide, and ensuring that the trolley body can be coaxially arranged with the carriage on the platform during the next loading, thereby improving the adaptability of the platform to the trolley body.
[0027] 8、By adding the support pad, when the trolley body is lifted as a whole, the walking wheel group is suspended when entering the adjustment area and rolls against the support pad when entering the normal position area. Therefore, when the front end of the trolley body is aligned and enters the normal position area, the walking wheel group can be supported by the support pad, so that the trolley body is supported by the alignment wheel group, the walking wheel group and the steering wheel as a whole, thereby improving the support stability of the trolley body and ensuring the support stability of the trolley body during loading under the premise of aligning the front end of the trolley body.

[0043] Example 1
[0044] Reference Figures 1-6 As shown, a high-density vehicle loading system includes:
[0045] Platform 1 is coaxially located at the rear end of the corresponding carriage 2. The top center of platform 1 is provided with a guide member 11 extending along the axial direction. The left and right sides of the front end of platform 1 are respectively provided with clamping members 12 that are driven by clamping drive assembly 13 to move in opposite directions or in opposite directions. The two clamping members 12 are used to clamp and fix the carriage 2 in opposite directions or to move away from the carriage 2 in opposite directions.
[0046] The transport vehicle body 3 has a cargo-carrying mechanism on one side for carrying goods and driven to move laterally by a lateral drive device 35. The bottom of the transport vehicle body 3 is provided with a set of front and rear walking wheels 4 and a set of swaying wheels 5, as well as several sets of guide wheels 6 distributed front and rear. The walking wheels 4 are driven to rotate back and forth by the walking drive device 41, and the swaying wheels 5 are driven to swing left and right by the rotation drive device 51. The guide wheels 6 are spaced apart and roll against the left and right sides of the guide member 11. The transport vehicle body 3 is provided with distance sensing devices on the left and right sides respectively. Specifically, the walking drive device 41 includes a motor, a belt connecting the motor rotation drive end and the walking wheels, and the distance sensing device is a photoelectric sensor.
[0047] Specifically, the loading system also includes a gantry crane 31 for transporting goods onto the platform 1 and placing them on the fork carriage 32 of the transport vehicle body 3.
[0048] The above structure, through the addition of clamping members 12, ensures that after the platform 1 and the corresponding carriage 2 are coaxially aligned and the front end is connected to the rear end of the carriage 2, the clamping drive assembly 13 can drive the two clamping members 12 to move towards each other and clamp and fix the carriage 2. This ensures that the platform 1 and the carriage 2 remain coaxially aligned during loading. Furthermore, through the cooperation between the guide member 11 and several sets of guide wheel sets 6, the transport vehicle 3 remains coaxially aligned with the carriage 2 as it moves on the platform 1 and enters the carriage 2. The feeding mechanism can accurately place the goods centered on the loading mechanism. Moreover, through the cooperation between the front-to-back rotating walking wheel set 4 and the left-to-right swinging directional wheel set 5 and the distance sensing device, the transport vehicle 3 is prevented from tilting as it enters the carriage 2 due to the unevenness of the carriage 2's floor. When loading, the sway wheel set 5 can be quickly adjusted to return to center by swinging left and right, thus ensuring that the transport vehicle 3 is always coaxially aligned with the carriage 2 during the loading process. This ensures that when goods are already filled on one side of the same row of the carriage 2, the transport vehicle 3 can transport the next batch of goods to the correct position and the loading mechanism can be moved laterally to load the next batch of goods into the empty space. Furthermore, when loading the last row of goods closest to the door of the carriage 2, the transport vehicle 3 can be aligned with the carriage 2 by the guide 11 and several sets of guides on the platform 1. Only the loading mechanism moves laterally to load the goods, which greatly improves the stability and accuracy of the goods loading, increases the loading efficiency and density, and avoids the situation where the transport vehicle 3 is tilted, causing the loading mechanism to collide and damage the goods inside the box or the side wall of the container during loading.
[0049] In order to improve the adjustment efficiency of the swing wheel group 5 to the trolley body 3, the number of the walking wheel group 4 is two groups and is arranged on the left and right sides of the front part of the trolley body 3, the number of the swing wheel group 5 is one group and is arranged on the rear side of the middle part of the trolley body 3, the distance between the swing wheel groups 5 is arranged and distributed on the left and right sides of the guide 11, so that the effect of quickly adjusting the trolley body 3 to the trolley body 3 by one swing wheel group 5 arranged in the middle part can be realized; in order to improve the guiding effect of the guide wheel group 6, the number of the guide wheel group 6 is two groups, which are respectively the front guide wheel group 61 and the rear guide wheel group 62 distributed in the middle part of the trolley body 3, the front guide wheel group 61 is arranged on the rear side of the two walking wheel groups 4, and the rear guide wheel group 62 is arranged on the rear side of the swing wheel group 5, so that by arranging the rear guide wheel group 62 and the front guide wheel group 61 respectively on the rear side of the swing wheel group 5 and the rear side of the walking wheel group 4, the process of the trolley body 3 retreating from the carriage 2 to the platform 1, the swing wheel group 5 is accurately moved to the left and right sides of the guide 11 through the limiting cooperation of the rear guide wheel group 62 and the guide 11, and the two walking wheel groups 4 are accurately moved to the left and right sides of the guide 11 through the limiting cooperation of the front guide wheel group 61 and the guide 11, the guiding stability and accuracy of the guide wheel group 6 are improved.
[0050] In order to improve the stability of the swing of the swing wheel group 5, the swing wheel group 5 includes two rudders 53 connected by a steering seat 52 and distributed on the left and right sides of the guide 11, the steering seat 52 is rotatably connected to a fixed seat 54 installed on the bottom of the trolley body 3, an outer gear ring 521 is sleeved on the outer side of the steering seat 52, the rotating driving device 51 is arranged on the side of the fixed seat 54 and the driving end is engaged with the outer gear of the outer gear ring 521 through a driving gear 511, and the fixed seat 54 is internally provided with a walking motor 541 for driving the two rudders 53 to rotate and walk, specifically, the walking motor 541 is a servo motor. Thus, the rudders 53 are driven to swing through the engagement between the gear 511 and the outer gear ring 521 and are driven to rotate and walk by the walking motor 541, the swing stability and walking stability of the rudders 53 are improved, and the stability of the swing of the swing wheel group 5 is improved.
[0051] Specifically, the cargo carrying mechanism includes a portal frame 31 and a fork frame 32, the portal frame 31 is rotatably arranged on the front side of the trolley body 3 and is driven to rotate by a pitch cylinder 33, the portal frame 31 includes a longitudinal driving device 34 and a transverse driving device 35, and the fork frame 32 is arranged on the front end of the portal frame 31 and is driven to rise and fall by the longitudinal driving device 34 and is driven to move left and right by the transverse driving device 35.
[0052] In order to improve the stability of the transverse movement of the fork frame 32, the longitudinal driving device 34 is connected with a lifting frame 341, the transverse driving device 35 comprises a ball screw arranged on the lifting frame 341 and a screw rod motor for driving the ball screw to rotate, and the fork frame 32 is screwed with the ball screw.
[0053] Since the lifting platform 1 used by the existing loading system is relatively mature, it is costly to directly replace the whole lifting platform 1, therefore, in order to reduce the additional cost of the guide 11, the guide 11 comprises a plurality of guide blocks 111 and a positioning block 112 which are sequentially abutted along the axial center line of the platform 1 from back to front, the guide blocks 111 and the positioning block 112 are screwed on the top of the platform 1, and the left and right widths of the positioning block 112 gradually decrease towards the direction close to the carriage 2. Thus, the guide 11 is divided into a plurality of guide blocks 111 and a positioning block 112, so that the guide 11 can also be installed and used on the existing lifting platform 1, greatly reducing the additional cost of the guide 11, and through the positioning and guiding effect of the positioning block 112, the rear guide wheel can smoothly roll to the left and right sides of the plurality of guide blocks 111 after contacting the rear guide wheel, avoiding the existence of guide jamming, and improving the practicability of the guide 11.
[0054] In order to improve the stability of the clamping of the clamping member 12, the clamping driving assembly 13 is provided with two groups and is symmetrically arranged on the front end of the platform 1, one clamping driving assembly 13 comprises a mounting seat 131 fixedly arranged on the side of the platform 1, a clamping oil cylinder 132 having one end hingedly connected to the inner side of the mounting seat 131 and the other end movably penetrating the mounting seat 131 and hingedly connected to the clamping member 12, a plurality of sliding sleeves 133 fixedly penetrating the side wall of the mounting seat 131, a plurality of sleeve rods 134 having one end respectively connected to the clamping member 12 and the other end respectively slidingly penetrating the sliding sleeves 133, and a plurality of limiting rods 135 having one end respectively connected to the clamping member 12 and the other end respectively slidingly penetrating the mounting seat 131 and being limitedly arranged, specifically, the mounting seat 131 is arranged in an L shape with the opening facing inward, and the inner diameter of the through hole of the side wall of the mounting seat 131 is greater than the outer diameter of the clamping oil cylinder 132. The sleeve rods 134 stably guide the opposite movement or opposite movement of the two clamping members 12, the other end of the clamping oil cylinder 132 movably penetrates the mounting seat 131, and the force of the two clamping members 12 after being clamped towards each other is dispersed to the mounting seat 131 through the cooperation between the sliding sleeves 133 and the sleeve rods 134 and the radial abutment between the limiting rods 135 and the mounting seat 131, so as to assist in dispersing the force of the extension end of the clamping oil cylinder 132, thereby improving the stability of the clamping of the clamping member 12 and the service life of the clamping oil cylinder 132.
[0055] In order to further improve the stability of the clamping of the clamping member 12, both the clamping member 12 includes a connecting portion 121 connected to one end of the sliding sleeve 133 and the other end of the clamping oil cylinder 132, respectively, both the connecting portions 121 extend to the front side to protrude from the rear opposite side of the platform 1 and are fixedly provided with a clamping block 122, respectively, the sleeve rod 134, the limiting rod 135, and the clamping oil cylinder 132 are arranged side by side in front and back and are connected to the rear of the connecting portion 121; after the two clamping blocks 122 of the two clamping members 12 are clamped and fixed to the left and right sides of the rear end of the carriage 2. Thus, the connecting portion 121 is added to connect the sleeve rod 134 and the clamping oil cylinder 132 arranged side by side in front and back, which increases the connection points of the clamping member 12. When the two connecting portions 121 have a tendency to move towards each other and backward under the opposite pressure of the two clamping blocks 122 clamping the carriage 2, the sleeve rod 134 and the limiting rod 135 can assist the clamping oil cylinder 132 to support the connecting portion 121 from front to back, thereby further improving the clamping stability of the clamping member 12.
[0056] In order to accurately butt joint the carriage 2, the top front end of the platform 1 is provided with a cover plate 19 corresponding to the top of the two mounting seats 131; after the front end of the platform 1 is butt jointed with the rear end of the carriage 2, the cover plate 19 is turned to cover and abut on the inner bottom rear end of the carriage 2. The cover plate 19 arranged by turning can also improve the convenience of maintenance and replacement of the clamping driving assembly 13.

Therefore, after the plurality of guide blocks 111 are installed in the middle of the platform 1, the width of the left and right sides will not be uniform, therefore, in order to ensure that the guide wheel set 6 can accurately roll and fit on the side of the plurality of guide blocks 111 for guiding, the bottom of the carrier body 3 is fixedly provided with two guide structures 7 which are symmetrically distributed front and back. Each of the guide structures 7 comprises a guide seat 71, a guide rod 72 extending front and back is arranged in the guide seat 71, a guide block 73 is slidably sleeved on the guide rod 72, a spring 74 is fixed at one end and connected to the guide block 73 at the other end, a slide rod 75 extending left and right, two sliding blocks are slidably sleeved on the slide rod 75, two connecting rods 76 are hingedly connected to the two sliding blocks at one end and hingedly connected to the guide block 73 at the other end. Specifically, the guide rod 72 and the slide rod 75 are perpendicular to each other, one end of the spring 74 is fixed to the inner wall of the guide seat 71, and the other end is fixedly connected to the side of the guide block 73 away from the slide rod 75. The bottom of the guide seat 71 is provided with a slide hole extending left and right, the front guide wheel set 61 comprises two rotating shafts slidably penetrating the slide hole of the guide seat 71 on the front side and connected to the sliding block, and two front guide wheels rotatably sleeved on the lower end of the rotating shaft, the rear guide wheel set 62 comprises two rotating shafts slidably penetrating the slide hole of the guide seat 71 on the rear side and connected to the sliding block, and two rear guide wheels rotatably sleeved on the lower end of the rotating shaft. Thus, through the addition of the guide structure 7, the two front guide wheels and the two rear guide wheels can be elastically rolled and clamped on the left and right sides of the plurality of guide blocks 111, and through the linkage and positioning of the guide rod 72, the guide block 73 and the two connecting rods 76, the relative displacement between the two front guide wheels and the two rear guide wheels is the same, so that the front guide wheel set 61 and the rear guide wheel set 62 are always coaxial with the carriage 2 when they are rolled and clamped on both sides of the guide block 111. Under the premise of ensuring the guiding accuracy of the front guide wheel set 61 and the rear guide wheel set 62, the rolling and clamping spacing between the front guide wheels and the rear guide wheels is adjusted, and the adaptability of the guide wheel set 6 is improved.
[0060] It should be pointed out that the implementation principle and the technical effects of the embodiment are the same as those of the first embodiment, and for the sake of brevity, the embodiment is not mentioned in the embodiment. The corresponding content in the first embodiment can be referred to.
[0061] Embodiment three
[0062] In order to improve the stability of the straight walking of the trolley body 3, the front walking wheel set 4 does not have a swing function, and due to the unevenness of the inner bottom of the carriage 2, the trolley body 3 is easily tilted when walking from front to back towards the platform 1, and even if the front part of the trolley body 3 is moved back by the swing wheel set 5, it cannot be corrected. At this time, if the front part of the trolley body 3 is forcibly corrected by the rolling abutting cooperation of the guide wheel set 6 and the guide 11, the guide wheel set 6 is easy to damage or the walking wheel set 4 is easy to rub with the top of the platform 1 and damage, and further cause the guide wheel set 6 to deviate or the walking wheel set 4 to walk to one side, so that the trolley body 3 cannot be coaxially arranged with the carriage 2 on the platform 1, therefore, with reference to Figures 9-12 The difference between the embodiment and the embodiment one, the embodiment two or the embodiment three is:
[0063] In order to correct the front end of the trolley body 3 without damaging the guide wheel set 6 and the walking wheel set 4, the top of the platform 1 comprises an adjusting area 14 on the left and right sides and the front side of the positioning block 112, and a correcting area 15 on the left and right sides of the guide block 111. The adjusting area 14 is recessed and provided with a plurality of mounting grooves for mounting universal adjusting devices 16. The universal adjusting device 16 comprises a limiting seat 161 fixedly arranged in the mounting groove, a lifting seat 162 slidingly arranged in the limiting seat 161, and a ball 163 rotatably arranged in the top of the lifting seat 162. The lifting seat 162 and the limiting seat 161 are connected by an elastic member 164, and the upper part of the ball 163 is exposed and protrudes from the upper side of the adjusting area 14. When the trolley body 3 enters the platform 1 from front to back and the front part of the trolley body 3 is slightly inclined, the rolling abutting limiting between the front guide wheel set 61 and the guide member 11 makes the walking wheel set 4 walk through a plurality of balls 163 and be guided to the side by a plurality of balls 163, thereby correcting the front end of the trolley body 3, and the plurality of balls 163 are compressed and reset by the elastic member 164 after the walking wheel set 4 passes. The rolling guidance of the front part of the trolley body 3 is realized by the plurality of universal adjusting devices 16, so that the walking wheel set 4 does not generate friction with the platform 1, but generates rolling friction between the plurality of balls 163, thereby avoiding the forced correction of the front part of the trolley body 3 by the rolling abutting cooperation of the guide wheel set 6 and the guide member 11, which may cause damage to the guide wheel set 6 or the walking wheel set 4, and the friction between the walking wheel set 4 and the top of the platform 1, which may cause the guide wheel set 6 to deviate or the walking wheel set 4 to walk to the side, so that the trolley body 3 cannot be coaxially arranged with the carriage 2 on the platform 1. The stability of the trolley body 3 when reversing from front to back onto the platform 1 and cooperating with the guide member 11 is improved, the cooperation between the guide wheel set 6 and the guide member 11 is stable and smooth, the trolley body 3 can be coaxially arranged with the carriage 2 on the platform 1 during the next loading, and the adaptability of the platform 1 to the coaxial guidance of the trolley body 3 is improved.
[0064] It should be pointed out that the implementation principle and technical effects of the embodiment are the same as those of the first embodiment. For brevity, the embodiment is not mentioned in the description, and the corresponding content in the first embodiment, the second embodiment or the third embodiment can be referred to.
[0065] Embodiment Four
[0066] In order to improve the stability of the straight walking of the trolley body 3, the front walking wheel set 4 does not have a swing function, and due to the unevenness of the inner bottom of the carriage 2, the trolley body 3 is easily tilted when walking from front to back towards the platform 1, and even if the front part of the trolley body 3 is moved back by the swing wheel set 5, it cannot be corrected. At this time, if the front part of the trolley body 3 is forcibly corrected by the rolling abutting cooperation of the guide wheel set 6 and the guide 11, the guide wheel set 6 is easy to damage or the walking wheel set 4 is easy to rub with the top of the platform 1 and damage, and further cause the guide wheel set 6 to deviate or the walking wheel set 4 to walk to one side, so that the trolley body 3 cannot be coaxially arranged with the carriage 2 on the platform 1, therefore, with reference to Figures 13-15 The difference between the embodiment and the embodiment one, the embodiment two, the embodiment three or the embodiment four is:
[0067] In order to realize the alignment of the front end of the trolley body 3 without damaging the guide wheel set 6 and the walking wheel set 4, the top of the platform 1 is provided with two raised tracks 17 on the left and right sides of the guide 11 and the front end is inclined, the top of a positioning block 112 is inclined to form a guide surface 1121 that gradually increases in height from front to back, and the bottom of the trolley body 3 is transversely rotatable and provided with a plurality of steering wheels 8 corresponding to each group of guide wheel set 6, specifically, the front steering wheel 8 is located on the front side of the front guide wheel set 61, and the rear steering wheel 8 is located on the rear side of the rear guide wheel, to ensure that when the trolley body 3 reverses onto the platform 1, the front guide wheel set 61 first rolls against the positioning block 112 and then controls the steering of the front steering wheel 8, improving the stability of the front guide wheel set 61 in controlling the steering of the front steering wheel 8; thereby, through the addition of the raised guide and a plurality of steering wheels 8, in the case that the trolley body 3 enters the platform 1 from front to back and the front end of the trolley body 3 is slightly skewed, the two rudders 53 can be positioned by the positioning block 112 to the left and right sides of the plurality of guide blocks 111 and roll and walk on the two raised tracks 17 to raise the rear end of the trolley body 3, the plurality of guide wheel sets 6 roll against the left and right sides of the guide 11, the plurality of steering wheels 8 are limited in steering by the left and right guide wheel sets 6 and roll and rise to the top of the plurality of guide blocks 111 guided by the guide surface 1121, to raise the front end of the trolley body 3 and make the walking wheel set 4 hang in the air. The front end of the trolley body 3 is controlled by the rolling abutment between the front guide wheel set 61 and the positioning block 112, and the steering wheel 8 walks on the positioning block 112, and is not hindered by the walking wheel set 4 hanging in the air, thereby avoiding the forced alignment of the front end of the trolley body 3 by the rolling abutment of the guide wheel set 6 and the guide 11, which can cause damage to the guide wheel set 6 or damage to the walking wheel set 4 and the top of the platform 1, causing the guide wheel set 6 to deviate or the walking wheel set 4 to deviate, so that the trolley body 3 cannot be coaxially arranged with the carriage 2 on the platform 1, improving the stability of the trolley body 3 reversing from front to back onto the platform 1 and cooperating with the guide 11, ensuring that the cooperation between the guide wheel set 6 and the guide 11 can be stable and smooth, ensuring that the trolley body 3 can be coaxially arranged with the carriage 2 on the platform 1 during the next loading, improving the adaptability of the platform 1 to the coaxial guidance of the trolley body 3.
[0068] In order to improve the limiting strength of the guide wheel set 6, the distal sides of the two raised guides are upwardly folded to form limiting portions corresponding to the guide 11, and when the trolley body 3 walks on the platform 1, the guide wheel set 6 rolls against the guide 11 and the two limiting portions, and the two rudders 53 roll and walk on the raised tracks 17 and are limited between the guide 11 and the two limiting portions.
[0069] Since the walking wheel set 4 is suspended, the trolley body 3 is only supported by the swing wheel set 5 and the steering wheels 8, and the supporting force is insufficient when the trolley body 3 is loaded. Therefore, in order to ensure the stability of the trolley body 3 while realizing the swing of the front end of the trolley body 3, the top of the platform 1 includes an adjusting area 14 on the left and right sides of the positioning block 112 and a normal position area 15 on the left and right sides of the guide block 111. The normal position area 15 is provided with a support pad 18 corresponding to the walking wheel set 4 and having a slope at the front end. The support height of the lifting track 17 and the support pad 18 is the same, specifically, the support height of the lifting track 17 and the support pad 18 is 1-3mm, preferably 2mm. Therefore, through the slight lifting height, when the trolley body 3 is accidentally tilted up and down on the left and right sides before the walking wheel set 4 is suspended to swing the front end of the trolley body 3, the walking wheel set 4 will be supported by touching the ground, avoiding the situation that the trolley body 3 is tilted and separated from the guide piece 11. After the trolley body 3 is lifted as a whole, the walking wheel set 4 is suspended when entering the adjusting area 14 and rolls against the support pad 18 when entering the normal position area 15. Therefore, through the addition of the support pad 18, when the trolley body 3 is swung to the front end and enters the normal position area 15, the walking wheel set 4 can be supported by the support pad 18, so that the trolley body 3 is supported by the swing wheel set 5, the walking wheel set 4 and the steering wheel 8 together, improving the supporting stability of the trolley body 3, and ensuring the supporting stability of the trolley body 3 when loaded under the premise of realizing the swing of the front end of the trolley body 3.

For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
