[0048] like Figures 1 to 15 As shown, in this embodiment, the device for transporting and transferring heavy stone bricks includes: a vehicle body 200, a crane assembly 210, and a brick clamping hanger 230. The vehicle body 200 has a silo 201; the crane assembly 210 includes a column 70 disposed on the vehicle body 200, a suspension arm 80 pivotably disposed on the column 70, and a hook 91 disposed on the suspension arm 80 that can be raised and lowered. The hook 91 has a first transfer position located directly above the center of the silo 201 and a second transfer position located outside the silo 201 in a horizontal plane. The brick clamping hanger 230 includes a clamping claw 20 and a lifting member 30, and the hook 91 is hooked and matched with the lifting member 30.

[0049] To apply the technical solution of this embodiment, first, the heavy-weight stone brick handling and transfer device is opened to the front of the brick pile, and the clamp 20 is moved to the top of the brick pile (the second transfer position). The hook 91 of the crane assembly 210 is lowered, so that the clamp 20 moves down to the top layer of bricks to clamp the bricks. The hook 91 of the crane assembly 210 is lifted, and the bricks are lifted by the clamp 20. Next, the hook 91 is moved to the first transfer position, and the hook 91 of the crane assembly 210 is lowered. When the bricks are placed in the silo 201, the clamp 20 is released. Repeat the above operation until the silo 201 is full of bricks. Then, the heavy-weight stone brick handling and transfer device is opened to the front of the paving robot, and the hook 91 is moved to the first transfer position. The hook 91 of the crane assembly 210 is lowered, so that the clamp 20 moves down to the top layer of bricks in the silo 201 to clamp the bricks. Lift up the hook 91 of the crane assembly 210, and the bricks are lifted by the clamp 20. Next, move the hook 91 to above the discharge position of the paving robot (the second transfer position), and lower the hook 91 of the crane assembly 210. When the bricks are placed at the discharge position of the paving robot, release the clamp 20. Repeat the above operation until all the bricks in the silo 201 are transferred to the paving robot. In summary, by applying the technical solution of this embodiment, the bricks can be directly loaded, unloaded and transported through the device for handling and transferring heavy stone bricks, without having to rely on manual handling and the transportation method of ordinary trolleys. Therefore, the transportation efficiency is improved and the labor intensity of the staff is reduced.

[0050] It should be noted that the above-mentioned “center of the silo 201 ” refers to a range and is not limited to a central point.

[0051] like Figures 1 to 4 As shown, in this embodiment, the vehicle body 200 includes a vehicle chassis 202 and a plurality of limit rods 203 disposed on the vehicle chassis 202 and extending upward, and the space surrounded by the plurality of limit rods 203 forms a silo 201. The above structure makes the bricks stacked on the vehicle chassis 202 more orderly, and prevents the bricks from falling during transportation. In addition, the weight of the silo 201 of the above structure is small, which is conducive to weight reduction of the handling and transportation device.

[0052] like Figures 1 to 4As shown, in this embodiment, the plurality of limiting rods 203 include a plurality of first limiting rods 203a arranged at intervals along the front-to-back direction x of the chassis 202 and a plurality of second limiting rods 203b arranged at intervals along the left-to-right direction y of the chassis 202. The first limiting rods 203a are adjustable in position in the left-to-right direction y through the first adjustment structure 240, and the second limiting rods 203b are adjustable in position in the front-to-back direction x through the second adjustment structure 250. The above structure enables the handling and transfer device to limit bricks of various sizes, thereby increasing the versatility of the handling and transfer device. Specifically, the length and width of stone bricks are applicable within the range of 600mm-1000mm. Of course, in other embodiments, the size of the silo 201 can be adjusted to make the handling and transfer device applicable to stones of larger sizes.

[0053] Preferably, if Figure 1 As shown, in the present embodiment, the vehicle chassis 202 includes a front side, a rear side, a left side and a right side of the chassis, a first limiting rod 203a is arranged on one of the left side and the right side of the chassis, and a second limiting rod 203b is arranged on the front side and / or the rear side of the chassis, that is, one of the left side and the right side of the chassis does not have a limiting rod, thereby forming a side opening of the silo 201, and each time the bricks lifted by the boom 80 can be moved into the silo 201 through the side opening of the silo 201, thereby improving the efficiency of transferring the bricks and ultimately improving the transportation efficiency.

[0054] It should be noted that, in this embodiment, the silo 201 actually has an upper opening and a side opening, and the staff can choose which opening to load or unload from according to actual needs. Of course, limit rods can be set on the four sides of the chassis 202 for limiting ( Figure 3 and Figure 4 ), the limiting effect is better.

[0055] like Figures 1 to 4 As shown, in this embodiment, the first adjustment structure 240 includes a first crossbeam provided on the vehicle chassis 202 and a first adjustment frame provided on the first crossbeam, the first limit rod 203a is provided on the first adjustment frame, the first crossbeam has a plurality of installation positions for installing the first adjustment frame, the installation position of the first adjustment frame can be selected according to the size of the actual brick material, and the installation and fixation are performed by a quick-pull pin shaft. Similarly, the second adjustment structure 250 includes a second crossbeam provided on the vehicle chassis 202 and a second adjustment frame provided on the second crossbeam, the second limit rod 203b is provided on the second adjustment frame, the second crossbeam has a plurality of installation positions for installing the second adjustment frame, the installation position of the second adjustment frame can be selected according to the size of the actual brick material, and the installation and fixation are performed by a quick-pull pin shaft.

[0056] Preferably, a protective guide strip is provided on the inner surface of the limit rod, and the protective guide strip is fixed to the limit rod with screws to limit and prevent collision of the edge of the stone brick.

[0057] like Figure 1 and Figure 4 As shown, in this embodiment, the device for transporting and transferring heavy-weight stone bricks also includes: a control device 260 disposed on the vehicle body 200, and the vehicle body 200 and the crane assembly 210 are both electrically connected to the control device 260 to achieve control of the vehicle and the crane.

[0058] Preferably, in other embodiments, the device for transporting and transferring heavy stone bricks further comprises: a visual recognition device (not shown in the figure) arranged on the boom 80, the visual recognition device is electrically connected to the control device 260, the first adjustment structure 240 and the second adjustment structure 250 are both electrically controlled structures, and the control device 260 controls the first adjustment structure 240 and the second adjustment structure 250 to move according to the length and width of the brick material identified by the visual recognition device. Specifically, before the brick material is lifted for the first time, the brick material is photographed by the visual recognition device to obtain a brick material image, and the length and width values ​​of the brick material can be obtained according to the brick material image. The length adjustment is described below by taking the length adjustment as an example, the length of the idle area of ​​the trolley (the effective area where the brick material can be placed after removing the column 70) is subtracted from the length of the brick material, and then the difference is divided by 2 to obtain the distance between the second limit rod 203b and the edge of the trolley. The second adjustment structure 250 is adjusted according to the distance. Of course, the calculation method is not limited to this, as long as it can ensure that the brick material is limited to the middle part of the chassis 202.

[0059] Preferably, in other embodiments, the first adjustment structure 240 and the second adjustment structure 250 may be modules or other hydraulic structures.

[0060] Preferably, in other embodiments, the device for handling and transferring heavy-weight stone bricks further includes: a prompting device (not shown in the figure), which is arranged on the vehicle body 200 or the crane assembly 210, and the control device 260 obtains the center of the brick according to the visual recognition device. When the hook 91 coincides with the center of the brick in the horizontal plane, the control device 260 controls the prompting device to work. Specifically, in the process of taking out the bricks in the silo 201, when the hook 91 moves to the top of the center of the brick, the prompting device sends a prompting signal (sound signal and / or light signal) to remind the staff to move the clamp 20 to the preset position, and then control the hook 91 to be lowered. The above structure can effectively improve the efficiency of transferring bricks to the paving robot, thereby improving the transfer efficiency. It should be noted that the above-mentioned "center of the brick" refers to an area range, and does not only refer to the center point of the brick.

[0061] like Figures 5 to 9 As shown, in this embodiment, the boom 80 includes a boom 81 and a small arm 82, the first end of the boom 81 is pivotally connected to the column 70, the second end of the boom 81 is pivotally connected to the first end of the small arm 82, and the hook 91 is liftably disposed at the second end of the small arm 82. The crane assembly 210 also includes a driving device 92 for driving the hook 91 to rise and fall, and the hook 91 and the driving device 92 form a hook assembly 90.

[0062] By applying the technical solution of this embodiment, the boom 80 is subdivided into a rotatable boom 81 and a small arm 82. This segmented design enables the crane to achieve more flexible and precise lifting operations through the relative rotation of the boom 81 and the small arm 82 while maintaining a compact overall structure. The boom 81 can rotate around its connection point with the column 70 within a certain range, while the small arm 82 can continue to rotate at the end of the boom 81. This dual rotation mechanism further increases the spatial range of the crane to lift objects, allowing the crane assembly to lift bricks closer to the column 70. In summary, the technical solution of this embodiment has the following four advantages: First, through the synergistic effect of the column 70, the boom 81 and the small arm 82, the design enables the crane to cover a wider operating area and meet the needs of a complex and changing working environment. Second, the segmented swivel boom design enables the crane to be more accurately positioned above the target object, and it can operate flexibly even in narrow or crowded spaces. Third, due to the expansion of the operating range and the improvement of operational flexibility, the crane can complete the lifting task faster, reducing the operation time and labor costs. Fourth, the design scheme is suitable for a variety of operating scenarios, such as construction sites and warehouses, and has strong versatility and adaptability.

[0063] like Figure 5 , Figure 6 and Fig. 9 As shown, in this embodiment, the crane assembly also includes a limiting structure 100, which includes a first limiting protrusion 101 provided on the boom 81 and a second limiting protrusion 102 provided on the column 70. The boom 81 has a limiting position and a free rotation position. When the boom 81 is in the limiting position, the second limiting protrusion 102 stops the first limiting protrusion 101. When the boom 81 is in the free rotation position, the second limiting protrusion 102 does not interfere with the first limiting protrusion 101. The above structure makes the rotation angle of the boom 81 relative to the column 70 less than 360 degrees, avoiding excessive twisting of the cable of the drive device 92 and avoiding the occurrence of twisted wires. Preferably, in this embodiment, the rotation angle of the boom 81 relative to the column 70 is less than 350 degrees.

[0064] like Figure 5 , Figure 6 and Fig. 9As shown, in this embodiment, the column 70 includes a column body 71 and a mounting column 72 located at the upper end of the column body 71, the first end of the arm 81 is sleeved on the mounting column 72, the second limiting protrusion 102 is arranged on the upper end of the side surface of the column body 71, the first limiting protrusion 101 is arranged on the lower surface of the arm 81, and the lower surface of the first limiting protrusion 101 is lower than the upper surface of the second limiting protrusion 102. The above structure adopts a hard limiting method, which is simple in structure and easy to implement. Of course, in other embodiments not shown in the figure, the limiting method is not limited to hard limiting, and the purpose of limiting can also be achieved by electrical limiting, hydraulic limiting or pneumatic limiting.

[0065] like Figure 5 and Fig. 9 As shown, in this embodiment, a vertically arranged sleeve 811 is arranged at the second end of the upper arm 81, a C-shaped mounting seat 821 and a rotating shaft 822 passing through the opening of the C-shaped mounting seat 821 are arranged at the first end of the lower arm 82, and the sleeve 811 is sleeved on the rotating shaft 822. The above structure is simple, easy to install, and highly reliable.

[0066] like Figures 3 to 5 , Figure 8 and Fig. 9 As shown, in this embodiment, the driving device 92 includes an electric winch, and the steel wire rope 921 of the electric winch is connected to the hook part 91, and the crane assembly also includes: a limit plate 110 and a limit sensor 120. Among them, the limit plate 110 is arranged at one end of the steel wire rope 921 close to the hook part 91. The limit sensor 120 is arranged at the second end of the arm 82 and is located above the limit plate 110, and the electric winch operates according to the electrical signal of the limit sensor 120. Specifically, when the hoisted brick material reaches a certain height, the limit plate 110 contacts the limit sensor 120, and the limit sensor 120 sends an in-position signal to the outside, and controls the electric winch to stop winding according to the in-position signal to prevent the hook assembly 90 from being damaged.

[0067] Preferably, if Fig. 9 As shown, in this embodiment, the limiting plate 110 further includes a central column 119, and the central column 119 and the steel wire rope 921 are fastened together by a clamp. The above structure is simple and easy to install.

[0068] More preferably, if Figure 8 and Fig. 9 As shown, the limiting plate 110 includes a limiting piece, and a mounting slot extending from the edge of the limiting piece to the center is arranged on the limiting piece, and the steel wire rope 921 is passed through the mounting slot. The above structure is simple and easy to install.

[0069] like Figure 5 , Figure 7 and Fig. 9As shown, in this embodiment, the column 70 includes a lower column section 711 and an upper column section 712 which are hinged to each other, and the upper column section 712 is detachably connected to the lower column section 711 by a fastener 713. When the crane assembly is not working, the fastener 713 can be operated to fold the upper column section 712 and the lower column section 711, thereby reducing the height of the crane assembly and facilitating transportation and storage.

[0070] like Figure 7 and Fig. 9 As shown, in this embodiment, the upper column section 712 is connected to the lower column section 711 through a hinge 714, and the fastener 713 includes a clamp 7131, and the clamp 7131 and the hinge 714 are arranged on opposite sides of the column 70. The above structure enables the upper column section 712 and the lower column section 711 to be connected and fastened.

[0071] like Figure 7 As shown, in this embodiment, the fastener 713 further includes a detachable pin 7132, and the detachable pin 7132 is located between the hinge 714 and the clamp 7131 in the circumferential direction of the column 70. The above structure allows the upper column section 712 and the lower column section 711 to be provided with connecting pieces around them, so that the upper column section 712 and the lower column section 711 are more tightly connected.

[0072] Preferably, if Figure 5 and Figure 7 As shown, in this embodiment, the lower column section 711 has a wire passage, the upper end of the side wall of the lower column section 711 has a wire outlet 715 connected to the wire passage, and the side wall of the upper column section 712 has a wire clamping structure 716. The above structure allows the cables of the drive device 92 to be more hidden in the column 70, ensuring the service life of the cables. At the same time, the exposed cables can be constrained in a predetermined position to prevent the cables from swinging randomly.

[0073] like Figure 3 and Figure 4 As shown, in this embodiment, the crane assembly 210 is arranged at the rear of the vehicle body 200, and the transfer vehicle further comprises: a counterweight block 220, which is arranged at the front of the vehicle body 200. The above structure ensures that when the transfer vehicle is lifting bricks, the center of gravity is still located on the chassis of the vehicle body 200, thereby preventing the transfer vehicle from overturning.

[0074] The following is a brief introduction to the vehicle body 200:

[0075] The vehicle body 200 is assembled from the front and rear axles, the vehicle chassis 202, the steering handle, the electric box, the pedal frame, etc. The front and rear axles are fixed to the chassis frame by U-shaped screws, and the front axle is connected by a shock-absorbing spring; the steering handle is fixed to the vehicle chassis 202, and the steering gear is connected to the front axle steering linkage mechanism; the electric box is placed at the bottom of the vehicle chassis 202, and the electric box is composed of an electrical box and a battery. This vehicle adopts the battery charging and discharging method to provide direct current power to the transfer vehicle, avoiding the limitation of towing lines and on-site power supply. The pedal frame is suspended at the rear of the vehicle chassis 202 for the operator to stand and use with the vehicle.

[0076] like Figures 10 to 23 As shown, in this embodiment, the brick clamping hanger 230 includes a support assembly 10, the support assembly 10 includes a mounting seat 11, a support member 12 arranged on the mounting seat 11 and extending downward, the bottom surface of the support member 12 is a positioning support surface 121 that abuts against the upper surface of the brick material; the clamping jaw 20 includes two clamping arms 21 arranged crosswise on a vertical plane and a clamping block 22 arranged on the inner surface of the lower end of the clamping arm 21, the inner surface of the clamping block 22 forms a clamping surface 221 that abuts against the side wall of the brick material, the clamping arm 21 is pivotally arranged on the mounting seat 11, and the pulling member 30 is connected to the mounting seat 11. Specifically, the brick clamping hanger 230 is lowered, and when the positioning support surface 121 of the brick clamping hanger 230 contacts the upper surface of the brick material 1, the two clamping blocks 22 of the clamping jaw 20 are located on the outer side of the side wall of the brick material 1. Then the clamping jaw 20 clamps the side wall of the brick material 1, and then the brick material 1 is transferred to a preset position. In the above structure, the presence of the positioning support surface 121 can ensure that the two clamping blocks 22 are located outside the side wall of the brick material 1, thereby facilitating subsequent clamping.

[0077] like Figures 10 to 23As shown, in this embodiment, the support assembly 10 also includes a guide member 13 disposed on the mounting seat 11 and extending upward, the lifting member 30 includes a lifting structure 31 and a transmission structure 33 disposed on the lifting structure 31, and a matching structure 32 that matches the guide member 13 is disposed on the lifting structure 31. Under the guidance of the guide member 13, the lifting structure 31 is arranged to be raised and lowered relative to the support assembly 10, and the transmission structure 33 drives the upper end of the clamping arm 21 to rise and fall, the upper end of the clamping arm 21 rises, the clamping surfaces 221 of the two clamping blocks 22 of the clamping jaw 20 are close to each other, the upper end of the clamping arm 21 descends, and the two clamping blocks 22 of the clamping jaw 20 are moved. The clamping surface 221 is away from the clamping surface 221; the device for handling and transferring heavy-weight stone bricks also includes: a locking device 40, including a first buckle 41 arranged on the mounting seat 11 and a second buckle 42 arranged on the pulling member 30, the locking device 40 includes a locking state in which the first buckle 41 and the second buckle 42 are locked and a separation state in which the first buckle 41 and the second buckle 42 are separated. When the locking device 40 is in the locked state, the pulling member 30 is fixed to the supporting assembly 10 through the locking device 40, and when the locking device 40 is in the separation state, the pulling member 30 can be raised and lowered relative to the supporting assembly 10.

[0078] By applying the technical solution of this embodiment, when the brick clamping hanger is not lifting the brick material 1, the locking device 40 is in a locked state, the relative position between the support assembly 10 and the lifting member 30 remains unchanged, and the clamping claw 20 is opened. When it is necessary to clamp the brick material 1 on the upper layer of the brick stack, the brick clamping hanger is aligned with the brick material 1, and then the brick clamping hanger is lowered. When the positioning support surface 121 of the brick clamping hanger contacts the upper surface of the brick material 1, the two clamping blocks 22 of the clamping claw 20 are located on the outer side of the side wall of the brick material 1. At this time, the locking device 40 is switched to a separated state, and the brick material 1 begins to support the brick clamping hanger. Then, the brick clamping hanger is lifted up by the lifting member 30. Since the first buckle 41 is separated from the second buckle 42, although the lifting member 30 moves upward, the support assembly 10 is still located on the brick material 1. Since the lifting member 30 rises relative to the support assembly 10, the transmission structure 33 drives the upper end of the clamping arm 21 to rise. The upper end of the clamping arm 21 rises, and the clamping surfaces 221 of the two clamping blocks 22 of the clamping jaws 20 are brought closer to each other, thereby clamping the side wall of the brick 1. As the clamping force (positive pressure on the brick 1) of the two clamping arms 21 increases, the friction on the brick 1 increases. When the friction is large enough to be equal to the gravity of the brick 1, the brick 1 can be lifted up by the brick clamping and lifting device. When unloading bricks, the brick clamping and lifting device is lowered, and when the brick 1 reaches the brick placement position, the brick 1 contacts the brick placement platform. As the brick clamping and lifting device is further lowered, the brick 1 and the support assembly 10 do not move because they are supported by the brick placement platform, and the pulling and lifting member 30 continues to move downward. As the pulling and lifting member 30 moves downward, the transmission structure 33 drives the lower end of the clamping arm 21 to descend. The upper end of the clamping arm 21 descends, and the clamping surfaces 221 of the two clamping blocks 22 of the clamping jaws 20 move away from each other, thereby releasing the brick 1. When the brick placing platform fully supports the brick clamping hanger, the first buckle 41 and the second buckle 42 are locked. At this time, the lifting member 30 is lifted, and the support assembly 10 rises together with the lifting member 30, and the clamping claw 20 is always in an open state. By applying the technical solution of this embodiment, it is no longer necessary to use a hydraulic device, thereby reducing costs. In addition, the operation of clamping and releasing the brick material 1 is simple, and the staff can use it quickly and skillfully, thereby improving the applicability of the brick clamping hanger.

[0079] like Fig. 20 As shown, in this embodiment, the guide member 13 is a guide column, and the matching structure 32 is a matching hole.

[0080] like Fig.10 , Figures 13 to 16 and Fig.23As shown, in this embodiment, the clamping arm 21 includes two arm pieces 211 arranged opposite to each other, a connecting shaft 212 provided at the upper ends of the two arm pieces 211, and a mounting plate 213 provided at the lower ends of the two arm pieces 211, the clamping block 22 is provided on the inner surface of the mounting plate 213, the arm piece 211 is pivotally provided on the mounting seat 11, and the transmission structure 33 is driven and matched with the connecting shaft 212. The above structure enables the clamping block 22 to be provided longer, thereby making the clamping of the brick material 1 more stable.

[0081] like Fig.10 , Figures 13 to 17 and Fig.23 As shown, in this embodiment, the transmission structure 33 is a lifting rod, and when the locking device 40 is in a separated state, the upper surface of the lifting rod is a supporting surface for supporting the connecting shaft 212. Specifically, when the transmission structure 33 (lifting rod) rises, the connecting shaft 212 supported by the lifting rod also starts to rise. In the process of the two connecting shafts 212 rising, the two connecting shafts 212 slide on the lifting rod and approach each other. Since the two connecting shafts 212 are close to each other, the clamping surfaces 221 of the two clamping blocks 22 are close to each other to achieve the clamping of the side wall of the brick material 1. The above structure is simple, low in cost, and high in reliability. Of course, in other embodiments not shown in the figure, the transmission structure 33 may also include a driving rod and two sliders that can slide on the driving rod, and the two connecting shafts 212 are fixed on the driving rod through the sliders. Alternatively, the transmission structure 33 includes a driving rod, and two guide grooves are provided on the driving rod, and the connecting shaft 212 is penetrated in the two guide grooves.

[0082] Since the two connecting shafts 212 slide on the lifting rods during the rising process, the friction between the connecting shafts 212 and the lifting rods is easily damaged after long-term work. In order to solve the above problem, Fig.14 , Fig.17 and Fig.23 As shown, in this embodiment, the connecting shaft 212 includes a shaft body 214 and a friction ring 215 sleeved on the shaft body 214, the friction ring 215 is rotatable relative to the shaft body 214, and the lifting rod supports the friction ring 215. The above structure converts the sliding friction between the connecting shaft 212 and the lifting rod into rolling friction, thereby greatly reducing the friction force and ensuring the service life of the connecting shaft 212 and the lifting rod.

[0083] like Fig.14 , Fig.15 , Fig. 22 and Fig.23As shown, in this embodiment, the mounting base 11 includes a central base 111 and two mounting brackets 112 disposed on opposite sides of the central base 111. The mounting bracket 112 is disposed between two arm pieces 211 of the corresponding clamping arm 21, and the arm piece 211 is rotatably disposed on the mounting bracket 112 through a pivot 113. The above structure is simple and easy to install.

[0084] Since the sizes of bricks 1 to be laid in each project are different, in order to enable the brick clamping and lifting device to clamp bricks 1 of different sizes, such as Fig.14 , Fig.15 , Fig.21 and Fig. 22 As shown, in this embodiment, the central seat 111 includes a first guide cylinder 114 extending toward the two mounting brackets 112, and the mounting seat 11 also includes two connecting rods 115 inserted into the first guide cylinder 114, and the two connecting rods 115 are respectively fixedly connected to the two mounting brackets 112, and the two connecting rods 115 are connected to the first guide cylinder 114 through the first fixing member 118. Specifically, before lifting the brick material 1, it is necessary to adjust the overlapping length between the two connecting rods 115 according to the size of the brick material 1 (the shorter the size of the brick material 1, the longer the overlapping length between the two connecting rods 115). The above structure enables the brick clamping hanger to clamp brick materials 1 of different sizes, thereby improving the versatility of the brick clamping hanger. It should be noted that, since each arm piece 211 is rotatably arranged on the mounting bracket 112 through its own pivot 113, each arm piece 211 rotates independently, and even if the distance between the two pivots 113 changes, it does not affect the opening and closing of the entire clamping jaw 20.

[0085] like Fig.15 and Fig. 22 As shown, in this embodiment, a plurality of mounting holes 116 are arranged at intervals on the connecting rod 115, and the first fixing member 118 is a connecting pin that penetrates the mounting holes 116 on the two connecting rods 115. The above connection method is simple and easy to install and adjust.

[0086] like Fig.12 and Fig.15 , Fig.18 , Fig.19 and Fig. 22As shown, in this embodiment, the first buckle 41 is fixedly arranged on the mounting seat 11, the second buckle 42 is pivotally arranged on the hanging structure 31, and the second buckle 42 is divided into a gravity section 421 and a buckle section 422 by the pivot 113. Under the action of the gravity section 421, the buckle section 422 rotates in the first direction. The first buckle 41 is provided with a first guide inclined surface 411 and a first clamping surface 412, and the buckle section 422 is provided with a second guide inclined surface 423 and a second clamping surface 424. A limited position structure is provided on the hanging structure 31. 311, the buckle section 422 abuts against the limiting structure 311 so that the second guide slope 423 is located above the first guide slope 411 in the vertical direction. When the second buckle 42 is lowered, the first guide slope 411 abuts against the second guide slope 423 to rotate the buckle section 422 in the second direction opposite to the first direction. When the first clamping surface 412 and the second clamping surface 424 are opposite in the height direction, the second buckle 42 rotates in the first direction, and the first clamping surface 412 and the second clamping surface 424 are clamped and matched. Specifically, when unloading bricks, the brick clamping hanger is lowered, and when the brick material 1 reaches the brick placement position, the brick material 1 contacts the brick placement platform. As the brick clamping hanger continues to be lowered, the brick material 1 and the support assembly 10 do not move because they are supported by the brick placement platform, and the pull hanger 30 continues to move downward. As the lifting member 30 moves downward, the second guide slope 423 of the second buckle 42 begins to contact the first guide slope 411 of the first buckle 41, and the buckle section 422 rotates in the second direction. When the brick placing platform fully supports the brick clamping hanger, the second clamping surface 424 of the second buckle 42 drops to the same height as the first clamping surface 412, and the second buckle 42 begins to rotate in the first direction under the action of gravity, and the first clamping surface 412 and the second clamping surface 424 are clamped and matched to achieve automatic buckling. The above structure does not require the staff to manually buckle the first buckle 41 and the second buckle 42, reducing the workload of the staff.

[0087] like Figures 10 to 15 , Fig.17 , Fig.18 and Fig.21 As shown, in this embodiment, the connection direction of the two clamping blocks 22 is the first horizontal direction n, and the brick clamping hanger also includes: a limiter 50, the limiter 50 is arranged along the second horizontal direction m perpendicular to the first horizontal direction n, and the two ends of the limiter 50 in the second horizontal direction m have limiter rods extending downward, and the distances between the two limiter rods and the center of the mounting seat 11 are equal. The above structure enables the brick clamping hanger to be located in the middle of the brick material 1 in the second horizontal direction m, so that the brick material 1 can be lifted more stably.

[0088] like Fig.12 , Fig.15 , Fig.18 and Fig.21As shown, in this embodiment, the lower surface of the mounting seat 11 is provided with two second guide cylinders 117 extending in parallel along the second horizontal direction m, and the limiting member 50 includes two bending tubes 51 extending in opposite directions and penetrating into the corresponding second guide cylinders 117, and the bending tube 51 includes a horizontal rod 511 extending in the horizontal direction and a vertical rod 512 located at the end of the horizontal rod 511, and the vertical rod 512 forms a limiting rod, and the two horizontal rods 511 are connected to the corresponding second guide cylinders 117 through a second fixing member. The above structure makes the distance between the two vertical rods 512 in the second horizontal direction m adjustable, thereby meeting the limitation of bricks 1 of different widths.

[0089] like Fig.12 , Fig.14 , Fig.16 , Fig.18 , Fig. 20 and Fig. 22 As shown, in this embodiment, the support member 12 includes a plurality of support columns 122, which are adjustably arranged on the mounting seat 11 through an adjustment structure height, and the bottom surface of the support column 122 forms a positioning support surface 121. The above structure allows the distance between the positioning support surface 121 and the bottom surface of the clamping block 22 to be adjusted, thereby meeting the requirements for clamping bricks 1 of different thicknesses.

[0090] like Fig.10 and Fig.13 As shown, in this embodiment, the brick clamping hanger further includes a handle 60 disposed on the support assembly 10. The above structure facilitates the staff to move the brick clamping hanger, so that the brick clamping hanger can be moved to the top of the brick material 1, which is convenient for subsequent brick clamping.

[0091] The following is a detailed introduction to stone brick transportation:

[0092] The handling and transfer device is a device specially designed for the stone brick automatic back-smearing robot to transfer stones into the warehouse.

[0093] The stone brick paving scene is a public construction project. The site is generally large, and the stone brick materials are stacked as units, which are roughly evenly dispersed on the site. When the stone brick automatic back-smearing paving robot moves to the fixed-point construction, it is necessary to supply bricks to the robot's silo in time. The handling and transfer device is in an unloaded state, with the brick clamping hoist 230 placed on the vehicle chassis 202, and the column 70 of the crane assembly 210 is above the vehicle chassis 202. The whole is in a folded state to facilitate the movement of the entire vehicle. When bricks need to be transported, preparations should be made in advance:

[0094] The size of the plurality of limit rods 203 and the brick clamping hanger 230 is limited and adjusted to correspond to the size of the stone bricks to be transported.

[0095] De-stacking and loading bricks into the silo 201 of the transfer vehicle: the worker drives the handling and transfer device to the side of the brick stack and stops it steadily (the handbrake is pulled in place to prevent the transfer vehicle from slipping and other unstable situations), holds the handle 60 of the brick clamping hoist 230, and uses the rotation freedom of the large and small arms of the crane assembly 210 to reach the top of the brick stack, manually controls the electric winch to slowly lower the wire rope, and quickly embeds the brick clamping hoist 230 into the brick edge. At this time, the limit of the brick clamping hoist 230 in the brick thickness height direction is positioned with the brick edge limit, and the brick clamping hoist 230 is quickly and accurately placed in place and clamped, and the wire rope of the manually controlled electric winch is slowly lifted, and the lifting structure 31 is lifted by the hook 91 of the winch wire rope. The lifting structure 31 moves upward in a straight line under the guidance of the guide member 13 on the central seat 111. The T-shaped square tubes (lifting rods) extending on both sides pull the two connecting shafts 212. The two connecting shafts 212 move closer to each other, and then the two clamping arms 21 rotate at a small angle under the constraint of the hinge structure, so as to achieve the effect of clamping the bricks inward by the clamping blocks 22 on both sides. The brick clamping hanger 230 and the stone bricks are converted into a friction force to clamp the bricks, and the bricks are lifted by a manual remote control electric winch, and then the handle 60 of the brick clamping hanger 230 is manually dragged to the top of the multiple limit rods 203 and slowly lowered, and then the stone bricks are placed in place and released. The brick clamping hanger 230 is hoisted out of the multiple limit rods 203 as a whole, completing a complete process of loading bricks into the transfer vehicle silo 201. According to the above operation process, the stone bricks are continuously transferred to the silo 201 of the transfer vehicle until the brick silo of the transfer vehicle is full (the maximum brick loading height of the transfer vehicle frame is 500mm).

[0096] The stone bricks in the transfer vehicle silo 201 are transferred into the robot silo: the worker drives the fully loaded handling and transfer device to the side of the stone brick automatic back-smearing paving robot and stops it steadily (with the handbrake pulled in place to prevent the transfer vehicle from sliding down the slope and other unstable situations), repeats the above-mentioned unpacking and warehousing operations, and transfers the stone bricks in the transfer vehicle silo 201 into the robot silo to complete a transfer process cycle.

[0097] According to the above operation, the empty handling and transfer device is driven to the brick stacking point, the stone bricks at the brick stacking point are unstackered and stacked into the transfer vehicle frame bin, and then the special transfer vehicle full of stone bricks is driven to the stone brick automatic back-smearing paving robot, the stone bricks in the transfer vehicle frame bin are unstackered and stacked into the robot's material bin. With the stone brick automatic back-smearing paving robot material bin as the target point and the brick stack on the site as the starting point, the above operation process is repeated over and over again to effectively transfer the stone bricks.

[0098] During the transportation process of the device for handling and transferring heavy stone bricks, the crane assembly 210 can be quickly disassembled and folded in the middle section of the column, so that the overall height of the vehicle can be reduced (from 2 meters to 1.4 meters). The upper part of the bent crane is bent and placed on the vehicle chassis 202, so that the whole vehicle can be transported in a small size, which is convenient and fast.

[0099] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0100] 1. The mechanical claw clamp can quickly and firmly grab 1-2 stone bricks on the brick pile, and the maximum weight of the bricks to be grabbed is 140kg;

[0101] 2. The universal adjustable design of the claw and the vehicle body enables the grabbing and storage of bricks with a length and width range of 600mm-1000mm;

[0102] 3. Self-developed crane design, which realizes the movement and amplitude change of the two joints of the truck crane and the large and small arms, manual dragging and fixed point, and the design of quick-disassembly folding column realizes the small size transportation of the whole machine;

[0103] Fourth, anti-rollover design, the layout design of batteries and counterweights, etc., when an empty truck lifts a stone brick, the center of gravity is located inside the four-wheel chassis, and it is not easy to overturn.
