Technical Field

[0001] The present application relates to an automatic wall-building device, and more particularly to a clamp and a wall-building machine. Background Art

[0002] The most solid way to build a wall is to build it piece by piece. As it becomes difficult to recruit workers and the labor cost gradually increases, wall-building robots have gradually emerged. They can replace manpower to complete wall-building work and only need to be maintained on time, avoiding the problems of difficulty in recruiting and employing workers and the stability of work efficiency, while greatly reducing the possibility of work-related injuries.

[0020] The present application is not limited by the following embodiments, and the specific implementation method can be determined according to the technical solution of the present application and actual conditions.

[0021] Embodiment 1, as Figures 1 to 2 As shown, the clamp includes a displacement drive, a clamping drive, a rear plate 1, a first drive hinge shaft 2, a second drive hinge shaft 3, and a drive rack 4; a rear drive arm 5 is installed on the top of the rear plate 1 through the first drive hinge shaft 2, and a front drive arm 19 is installed on the top of the rear drive arm 5 through the second drive hinge shaft 3; the slidable drive rack 4 is perpendicular to the axial direction of the first drive hinge shaft 2 and is arranged horizontally, a drive round rod 22 is fixed to the lower side of the drive rack 4, and a rotating shaft sleeve 20 mounted on the drive round rod 22 is fixed to the middle part of the front drive arm 19; the axial directions of the first drive hinge shaft 2, the second drive hinge shaft 3, the drive round rod 22, and the rotating shaft sleeve 20 are all consistent; the drive rack 4 is connected to the clamping drive; the rear plate 1 is connected to a displacement drive that can drive the rear plate 1 to move along the length direction of the drive rack 4.

[0022] When taking the wall bricks, the displacement drive drives the rear plate 1 to move forward; when the rear plate 1 contacts the wall bricks to be taken, the clamping drive drives the driving rack 4 to move backward, the driving round rod 22 on the driving rack 4 moves synchronously, the rotating sleeve 20 rotates, and the rear driving arm 5 rotates counterclockwise around the second driving hinge shaft 3 until it is clamped on the other side of the wall bricks to be taken, at which time the wall bricks can be easily and firmly lifted. When the wall bricks are transported to the designated destination, the clamping drive drives the driving rack 4 to move forward, the driving round rod 22 on the driving rack 4 moves synchronously, the rotating sleeve 20 rotates, and the rear driving arm 5 rotates clockwise around the second driving hinge shaft 3 to release the clamped wall bricks, thereby automatically withdrawing the wall bricks. During the clamping and releasing process, the rear plate 1 remains stationary, and the rear driving arm 5 can be rotated. Due to the cooperation of the front driving arm 19 and the first driving hinge shaft 2, the vertical upward movement of the rear driving arm 5 occupies very little space, and the wall bricks on the top layer can be effectively placed.

[0023] The present application has a simple structure and is more reliable for fixing wall tiles. Moreover, since the clamping and unloading process requires little space, the wall tiles at the corners can also be effectively handled. There is no need for the existing clamping mechanism to require two plates to clamp and to lift the bricks vertically when unloading, which occupies a large amount of space. Even the wall tiles at the corners, wall tops, etc. can be effectively transported; it has a wide range of applicability.

[0024] like Figure 1 , 2 As shown, a rear driving arm 5 is installed at the two ends of the top of the rear flat plate 1 through the first driving hinge shaft 2, and each rear driving arm 5 corresponds to a second driving hinge shaft 3 and is installed with a front driving arm 19; a rotating sleeve 20 is provided at each end of the driving round rod 22, and each rotating sleeve 20 is fixedly connected to a corresponding front driving arm 19.

[0025] As shown in the figure, a soft clamping surface 13 is provided inside the front driving arm 19, so that the wall tiles can be clamped more stably.

[0026] Embodiment 2, as Figure 3 , 4 As shown, a wall-building machine includes an x-axis track 7, a base 8, a brick-setting platform 9, a column 10, a chassis assembly 11, an automatic stabilizer 12, and a clamp; the base 8 is connected to an x-axis drive and is slidably mounted on the x-axis track 7 through the x-axis drive; the brick-setting platform 9 is fixed to one side of the base 8, and the column 10 is fixed to the middle of the base 8; a first z-axis drive is provided in the chassis assembly 11 and is slidably mounted on the column 10 through the first z-axis drive; a y-axis drive is also provided in the chassis assembly 11 and is connected to a rear flat plate bracket 21 that can move along the y-axis through the y-axis drive, the clamp is installed on the rear flat plate bracket 21 and is correspondingly located above the brick-setting platform 9, and the clamping drive is installed in the chassis assembly 11; an automatic stabilizer 12 that can move along the z-axis is provided on the top of the column 10.

[0027] The working steps are as follows: the first step is to control the base 8 and the column 10 to move to the position where the wall is to be built through the x-axis drive;

[0028] In the second step, the bricks to be laid are placed on the brick placing platform 9, and the rear plate 1 is controlled to move forward by the y-axis drive (i.e., displacement drive). After the rear plate 1 contacts the bricks to be taken, the rack 4 is driven backward by the clamping drive control, and the rear driving arm 5 rotates to automatically clamp the bricks to be taken and stabilize them.

[0029] Step 3: The automatic stabilizer 12 is controlled to move upward by the second z-axis drive, and the top cone 18 abuts against the floor or other fixed parts;

[0030] Step 4: The chassis assembly frame 11 is controlled to rise as a whole through the first z-axis drive to transport the picked-up wall bricks to a set height;

[0031] Step 5: Control the rear flat panel support 21 and the fixture to move as a whole through the y-axis drive to deliver the picked-up wall tiles to the destination position (on the wall);

[0032] Step 6: The rack 4 is driven forward by the clamping drive control, and the rear drive arm 5 and the front drive arm 19 are extended to automatically release the wall tiles;

[0033] Step 7: Control the rear plate support 21 and the fixture to move as a whole and return to their original positions through the Y-axis drive;

[0034] Step 8: The chassis assembly frame 11 is driven and controlled to descend as a whole and return to its original position through the first z-axis;

[0035] Step 9: The automatic stabilizer 12 is controlled to descend by the second z-axis drive, and the top cone 18 is released from the floor or other fixings;

[0036] Step 10: Control the base 8 and the column 10 to move to the next wall to be built by driving the x-axis;

[0037] The present invention has strong stability and high precision, and the above steps can be repeated. The x-axis drive can be installed at the bottom of the base 8. The y-axis drive and the first z-axis drive can be installed in the chassis assembly frame 11.

[0038] like Figure 3 , 4 As shown, the y-axis is driven by a y-direction motor; a pair of rear flat panel brackets 21 are slidably installed in the chassis assembly frame 11 along the y-direction, and a y-direction rack 14 is provided on the rear flat panel bracket 21. The chassis assembly frame 11 is fixedly installed with a driving shaft 15 located above the pair of flat panel brackets; the y-direction motor is connected to the driving shaft 15 through a first chain 16, and a first gear 17 is provided on the driving shaft 15 and meshes with the y-direction rack 14 through the first gear 17.

[0039] The driving rack 4 can be mounted with a driving gear 6 and connected to the clamping driving output end through the driving gear 6. The x-axis drive, y-axis drive, first z-axis drive, second z-axis drive and respective connecting parts in this application are all existing known public technologies, and their purpose is track transmission, which can be electric drive or hydraulic drive. Here, only one way is provided for the y-axis motor, chain, and driving shaft 15 to cooperate and drive the rear flat plate bracket 21 to move. The connection structure of other components can refer to the connection method in this paragraph, and can also refer to other existing known public connection methods, which will not be repeated here.

[0040] Each motor can be controlled by an existing single-chip microcomputer to realize the working steps of the whole machine.

[0041] The top of the clamp is fixed to the end of the rear flat plate support 21.

[0042] like Figure 3 , 4 As shown, the automatic stabilizer 12 is installed with a second z-axis drive and is slidably installed on the top of the column 10 through the second z-axis drive; a top cone 18 is provided on the top of the automatic stabilizer 12.

[0043] Because the present application adopts the column 10 for lifting, it has a simple structure, low cost, and can meet the requirements of walling at any height. It eliminates the disadvantage of the truss-type walling height limitation in the prior art, but the stability of the column 10 is not as good as the truss type. The cooperation of the column 10 and the automatic stabilizer 12 can enhance the overall strength of the equipment and improve the stability when carrying wall bricks.

[0044] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0045] The above technical features constitute the embodiments of the present application, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the needs of different situations.
