Description
Technical Field
[0001] This invention relates to the field of municipal construction equipment, and in particular to a square tile transfer clamp. Background Technology
[0002] Paved pavement refers to pavement that has been hardened or decorated with paving bricks. In daily life, it is most commonly seen on the sidewalks on both sides of highways. The paving bricks used in paved pavement are mainly square bricks. Paved pavement is also widely used in large outdoor squares such as squares, residential areas, and parking lots. There are many types of paving bricks. According to the variety, there are unglazed bricks, glazed bricks, unglazed polished bricks, vitrified bricks, inlaid bricks, and inlaid polished bricks. Different types of paving bricks have slightly different applications, but they all have common characteristics such as high weight, high strength, and a certain thickness. This makes it inconvenient for workers to handle them during the final construction process.
[0003] As is well known, road paving currently relies heavily on manual labor. Paving bricks are transported to the construction section in stacks, and then workers transport them to the paving stations for installation. Due to varying site conditions and brick placement, this process still requires manual labor combined with trolleys. Workers manually move the bricks one by one from the stacks to the trolleys, then dump them at the designated location. The dumped bricks are often piled haphazardly, resulting in overlapping and misalignment. This makes it difficult to remove bricks from the pile when needed, posing a risk of worker injury from collapsing stacks. Retrieving bricks from irregular piles is also inconvenient and hinders on-site operations. Therefore, workers sometimes try to neatly stack the transported bricks, but this increases the number of steps and creates potential coordination issues. Furthermore, existing technologies, such as those described in application number 2021105958, present further challenges. Patent 27.1, titled "A Square Brick Transfer Device," provides a bracket for a stack of square bricks that allows for the separation of entire stacks of bricks into individual vertical stacks, enabling individual operation of each stack. A matching picking device is used to remove and transfer each stack to the work station. However, in actual use, the worker is still presented with a small stack of bricks. When using such bricks, one side of the brick must be tilted up to allow for hand access before the entire stack can be moved to the paving location. There is room for improvement in the worker's operation during this process. Compared to the traditional method of extracting bricks from a jumbled pile, this neat arrangement is safer and faster, but the overly neat stacks make it difficult to find a suitable point of leverage when reaching for the bricks. This results in a complex action requiring the coordination of both hands, which needs to be repeated. Therefore, optimizing this action could fundamentally improve paving efficiency and reduce worker workload.
[0004] Therefore, this invention combines the advantages and disadvantages of the above two methods to provide a new terminal transportation device for square bricks, which fundamentally improves the efficiency of brick laying and reduces the labor intensity of workers. Summary of the Invention
[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a square floor tile transfer clamp, which effectively solves the problems mentioned in the background art.
[0006] The technical solution to the problem includes an arc-shaped support frame. Multiple arc-shaped plates are coaxially spaced and evenly distributed on the inner side of the support frame. A clamping electric cylinder is fixedly installed at each end of the left and right sides of each arc-shaped plate. An arc-shaped rod is fixed to the front side of the arc apex of each arc-shaped plate and slidably mounted on the support frame. An arc-shaped rack is coaxially fixed to the arc-shaped plate below each arc-shaped rod. An incomplete gear, rotatably mounted on the support frame, meshes with the outer side of each arc-shaped rack. The incomplete gear penetrates the support frame. A vertical rod is located on the front side of the multiple incomplete gears. A support rod is fixed radially on the outer edge of the toothless portion of each incomplete gear. The support rods on two adjacent incomplete gears are arranged symmetrically. A connecting rod is hinged to the free end of each support rod, and the free end of the connecting rod is hinged to the vertical rod. A first handle, parallel and spaced apart from the vertical rod, is located at the front end of the vertical rod. A second handle, radially mounted along the arc-shaped plate, is located above the support frame.
[0007] Preferably, the support frame is a U-shaped structure with arc-shaped slides at both ends for arc-shaped rods to pass through. The arc-shaped slides have a rectangular cross-section, and the arc-shaped rods have a rectangular cross-section. The support frame has multiple through slots evenly distributed at intervals on the top and bottom for incomplete gears to pass through and be installed.
[0008] Preferably, both the first handle and the second handle are fitted with anti-slip rubber sleeves, and the second handle is provided with an auxiliary support arm, one end of which is fixed to the second handle and the other end is fixed to the support frame.
[0009] Preferably, the cylinder body of the clamping electric cylinder is fixed on the arc plate, the protruding end of the clamping electric cylinder passes through and extends into the inner side of the arc plate, and a clamping plate is fixed to the protruding end of the clamping electric cylinder, with an anti-slip pad provided on the inner side of the clamping plate.
[0010] Preferably, a limiting block is provided on the hinge shaft of the connecting rod and the support rod. The hinge shaft is fixedly connected to the connecting rod and rotatably connected to the support rod. The support rod is provided with an arc-shaped groove for the limiting block to slide in, and the limiting block can only rotate within the arc-shaped groove.
[0011] Preferably, the bracket for the brick stack is a split type, which can separate adjacent brick stacks front and back to form a gap.
[0012] This device transforms a neatly stacked pile of bricks during transport by rotating adjacent bricks at an angle, creating space between them for easy one-handed operation. Only the gripping and holding positions need to be changed during transport; the handle does not interfere with normal transport. Switching hands during transport also allows operators to rest their hands. When the pile is vertical, gravity prevents it from rotating. After the pile rotates 90 degrees, there is no pressure between adjacent bricks, effectively reducing friction. The weight of the entire pile allows for easy rotation of the bricks, ultimately enabling rotation between them. This device adds a new function to transport equipment, and this function is not simply an addition but an improvement on the transport process. This makes the device compact, functionally complete, easy and reliable to operate, and has low production costs, facilitating large-scale market application. Attached Figure Description

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0019] Depend on Figures 1 to 5As can be seen, the present invention includes an arc-shaped support frame 1. Multiple arc-shaped plates 2 are coaxially and evenly distributed on the inner side of the support frame 1. Each arc-shaped plate 2 has a clamping electric cylinder 3 fixedly installed at both ends of its left and right sides. An arc-shaped rod 4 is fixedly installed on the front side of the arc top of each arc-shaped plate 2. The arc-shaped rod 4 is slidably installed on the support frame 1. An arc-shaped rack 5 is coaxially fixed on the arc-shaped plate 2 below each arc-shaped rod 4. An incomplete gear 6 is rotatably installed on the support frame 1 on the outer side of each arc-shaped rack 5. The incomplete gear 6 passes through the support frame 1. A vertical rod 7 is provided on the front side of the multiple incomplete gears 6. A support rod 8 is fixed on the outer edge of the toothless part of each incomplete gear 6 along its radial direction. The support rods 8 on two adjacent incomplete gears 6 are arranged symmetrically left and right. A connecting rod 9 is hinged to the free end of each support rod 8. The free end of the connecting rod 9 is hinged to the vertical rod 7. A first handle 10 is provided at the front end of the vertical rod 7, parallel to and spaced from it. A second handle 11 is provided on the top of the support frame 1 along the radial direction of the arc-shaped plate 2.
[0020] In order to achieve sliding support for the arc rod 4 and facilitate the installation of the incomplete gear 6, the support frame 1 is a U-shaped structure. Both ends of the support frame 1 are provided with arc-shaped slide rails 12 through which the arc rod 4 can pass. The cross section of the arc-shaped slide rail 12 is rectangular. The arc rod 4 is a rod with a rectangular cross section. The support frame 1 has multiple through slots evenly distributed at intervals on the upper and lower sides, which allow the incomplete gear 6 to pass through and be installed.
[0021] To facilitate the handling of this device, both the first handle 10 and the second handle 11 are fitted with anti-slip rubber sleeves. The second handle 11 is provided with an auxiliary support arm, one end of which is fixed to the second handle 11 and the other end is fixed to the support frame 1.
[0022] In order to achieve a better clamping effect of the clamping electric cylinder 3, the cylinder body of the clamping electric cylinder 3 is fixed on the arc plate 2, the protruding end of the clamping electric cylinder 3 passes through and extends into the inner side of the arc plate 2, and a clamping plate 13 is fixed to the protruding end of the clamping electric cylinder 3. The inner side of the clamping plate 13 is provided with an anti-slip pad.
[0023] To facilitate limiting the rotational position of the connecting rod 9 and the support rod 8, a limiting block is provided on the hinge shaft of the connecting rod 9 and the support rod 8. The hinge shaft is fixedly connected to the connecting rod 9 and rotatably connected to the support rod 8. The support rod 8 is provided with an arc-shaped groove for the limiting block to slide in, and the limiting block can only rotate within the arc-shaped groove.
[0024] To facilitate the clamping of the brick stacks, the brick stack bracket is a split type, which can separate adjacent brick stacks front and back to form a gap.
[0025] The specific working process of this invention: The bracket used for the brick stack corresponding to this device should be as follows: Figure 5The bracket shown consists of three long strips. A slide rail is located at the bottom of the bracket, which is fixed to the bottom of the middle long strip. The long strips on the front and back sides are slidably installed on the bracket. When the three long strips are close together, they form a square plate. Alternatively, the bracket can be a double-layer bracket, with the lower bracket being a complete square bracket and the upper bracket consisting of three long strips. After transportation to the destination, the upper and lower brackets are separated by a forklift. This type of bracket is a well-known technology and will not be described in detail. In principle, the stack of bricks to be picked up should have three sides free of obstructions.
[0026] When using this device, the clamping cylinder 3 is first retracted to allow the clamping plate 13 to not obstruct the curved plate 2 from wrapping and limiting the brick stack from one side. During use, the worker holds the first handle with one hand and the second handle with the other, driving the first handle towards the support frame 1. This process causes the first handle to drive the vertical rod 7 via the connecting rod 9, which in turn drives the support rod 8, rotating the incomplete gear 6. The incomplete gear 6 meshes with the curved rack 5, driving the curved plate 2 so that the ends of multiple curved plates 2 on the same side are in the same vertical plane. The limiting during this process is achieved through the limiting block and the curved groove on the hinge shaft between the connecting rod 9 and the support rod 8. Simultaneously, the curved groove and the limiting block ensure that the angle between the connecting rod 9 and the support rod 8 is always less than 180 degrees. Later, the angle is reset to meet the force application requirements. At this point, the clamping cylinder retracts, and the first handle... The handle ensures that the opening of the arc-shaped plate 2 faces backward, thus wrapping and supporting the brick stack from the front. After wrapping, the extension end of the clamping electric cylinder extends, clamping the left and right side walls of the brick on the two clamping electric cylinders 3 on one arc-shaped plate 2. Multiple arc-shaped plates 2 limit the movement of multiple bricks in the stack. After completion, holding the second handle lifts the clamped brick in the stack as a whole and removes it from the stack. After completion, while holding the first handle, release the second handle. This process changes the original vertical brick stack to a horizontal position. At this time, under the gravity of the brick stack, the first handle moves away from the support frame 1. During this movement, the connecting rod 9 and support rod 8 are pulled, thereby driving the incomplete gear 6 to mesh with the rack and pinion to rotate, thus realizing the movement of the arc-shaped plate 2 that clamps the brick. Figure 1 Towards Figure 2 After the transformation is completed, the worker holds the second handle again to make the brick stack return to vertical. During this process, the distance between the first handle and the support frame 1 is maintained. When the brick stack returns to vertical again, the first handle can be released and the brick stack can be transported to the paving position. At this time, the brick stack forms an alternating staggered state, which is convenient to pick up.
[0027] After reaching the designated position, the control clamping cylinder 3 releases the clamp, the clamping plate 13 moves closer to the arc plate 2 and removes the device from one side of the brick stack. After removal, the first handle is pushed so that the first handle drives the vertical rod 7 to drive the connecting rod 9 and the support rod 8 to drive the incomplete gear 6 to reset and rotate. During this process, the arc plate 2 is reset by the arc rack 5, and then the next group of bricks can be clamped and rotated.
[0028] The present invention has the following advantages:
[0029] 1. This device requires the use of a split-type bracket to ensure that three sides of the brick stack are unobstructed during transport. It allows the device to wrap and clamp the brick stack from one side. As the terminal transport equipment for brick stacks, this device can conveniently and quickly clamp and transport a stack of bricks. At the same time, by changing the gripping position during transport, it can easily achieve the transformation of the originally neat stack of bricks into a staggered stack after rotation. There is space between adjacent bricks on the stack that is convenient for manual force application. With the help of this space, workers can pick up bricks with one hand, which greatly reduces the labor intensity of workers and improves construction efficiency. The brick stack still maintains a neat state, has a stable structure, occupies a small area, and is safe to operate.
[0030] 2. This device transforms a neatly stacked pile of bricks during transport by rotating adjacent bricks at an angle, creating space between them for easy one-handed operation. Only the gripping position needs to be changed during transport, and the holding position is changed during the same process. The handle does not affect normal transport, and the ability to switch hands during transport allows the operator to rest their hands effectively. When the brick stack is vertical, gravity prevents it from rotating. After the bricks rotate 90 degrees, there is no pressure between adjacent bricks, effectively reducing friction. The weight of the entire stack allows for easy rotation of the bricks, ultimately achieving rotation between them. This device adds a new function to the transport equipment, and this function is not simply an addition but an improvement on the transport process. This makes the device compact, functionally complete, easy and reliable to operate, and has low production costs, facilitating large-scale market application.
[0031] 3. Since the two incomplete gears 6 rotate in opposite directions when driving the arc plate 2 to rotate, the rotation directions between two adjacent arc plates 2 are also opposite. This makes the relative motion angle between two adjacent bricks twice the rotation angle of the arc plate 2. Therefore, it is possible to achieve an effective brick-picking space by rotating between the upper and lower bricks with a small rotation angle, making the entire device structure more ingenious and more practical.
