Description

Technical Field

[0001] The utility model belongs to the field of concrete block production equipment, and more specifically relates to a staggered alignment device for high-level concrete block stacks. Background Art

[0002] In the autoclaved aerated concrete block production industry, after the blocks are produced, they need to be packaged and shipped. In order to improve the packaging efficiency, the produced blocks are usually stacked into a stack layer with a certain height to achieve a one-time packaging of a large number of blocks.

[0003] However, when stacking and packing, the lower part of the stacking layer is often not level due to the environment or equipment operation errors during rotation and positioning in the previous process, resulting in misalignment, which affects the subsequent packing of blocks. On this basis, although the blank translation machine in the previous process can be used to align the misalignment, it will greatly affect the overall speed of the packing line and reduce the packing efficiency. Therefore, in view of this situation, a stacking misalignment alignment device that does not affect the production work of the packing line is needed to solve this problem.

[0004] The Chinese patent application number is CN201320139695.2, and the patent document with the publication date of October 30, 2013, discloses an aerated concrete block conveying device, which is provided with a blank and a tray alignment device, and the blank and tray alignment device includes a baffle, a hinged four-bar mechanism, and a cylinder; the hinged four-bar mechanism is a parallelogram mechanism, the frame of the hinged four-bar mechanism is arranged on a fixed seat, and the cylinder body of the cylinder is hingedly connected to the fixed seat; the baffle constitutes the connecting rod of the hinged four-bar mechanism; the piston rod end of the cylinder is hingedly connected to the baffle; the baffle is parallel to the side of the finished block blank. The above technical solution can realize the alignment of the blank and the end face of the tray in the production of the aerated concrete block packaging line, ensure the smooth operation of the packaging line, and facilitate the full automation of the aerated concrete block packaging line.

[0005] The Chinese patent application number is CN201510140711.3, and the publication date is July 15, 2015. The patent document discloses an aerated concrete block assembling machine, which includes a stacking area, a breaking plate area, and a assembling and clamping area. In the stacking area, the breaking plate area, and the transition zone between the three areas, a plurality of driven motor rollers and active motor rollers are alternately arranged; in the assembling and clamping area, a assembling ferry car is arranged, and two conveying rollers are arranged on the assembling ferry car. A positioning buffer assembly is fixed at the rear end of the assembling ferry car, and a push cylinder is arranged at the bottom of the assembling ferry car. This solution can well solve the problem of assembling flatness in the post-autoclave packaging process and improve the efficiency of assembling.

[0006] Both of the above-mentioned schemes are provided with corresponding alignment devices for aligning the building blocks. However, both of them adopt the method of arranging the alignment devices on both sides of the bottom of the platform for carrying the building blocks. Although this arrangement can make the building blocks on the carrying platform become level, when the building blocks are stacked high in order to improve the efficiency of building block packaging, and the staggered joints appear at a higher position of the stacking layer, the alignment device arranged at the bottom of the carrying platform often fails to play a role, that is, this scheme is not suitable for the staggered alignment of the high-layer building block stacking layer. Summary of the invention

Therefore, the scope of the present invention is limited only by the appended claims.

[0034] Example 1

[0035] A staggered alignment device for a high-layer concrete block stack is used to align the high-layer block stack in advance when the blocks are stacked and packaged, so as to eliminate the staggered joints between different layers of blocks in the height direction when the blocks are stacked, and ensure the subsequent packaging effect of the high-layer block stack. The specific structure and working principle of the device are described in detail below.

[0036] like Figure 1 As shown, the device mainly includes a frame, a lifting component and an alignment component 9.

[0037] Among them, the frame is the installation body of the entire device, including four columns 1 and a beam 5 installed above the four columns 1. A pull rod 4 is fixedly connected between two adjacent columns 1. The various components are connected by welding or bolts to form a frame fixed to the ground. The setting of the pull rod 4 is mainly used to improve the strength of the frame and ensure the installation stability of the device.

[0038] The lifting assembly includes a lifting mechanism 2, a lifting rod 3, a sprocket 7 and a chain 8. A slide rail is provided on the column 1 in the height direction, the lifting rod 3 is horizontally arranged and slidably installed on the column 1 through a slider matching the slide rail, and the lifting mechanism 2 drives the lifting rod 3 to rise and fall. In this embodiment, the lifting mechanism 2 is an oil cylinder, one end of which is fixed to the ground, and the other end is connected to the middle of the lifting rod 3. The sprocket 7 is installed on the upper part of the frame, one end of the chain 8 is connected to the lifting rod 3, and the other end passes through the sprocket 7 and is connected to the alignment assembly 9, which is used to align the high level of the block stack.

[0039] like Figure 2 As shown, the alignment assembly 9 includes a frame 10, and the frame 10 is welded into a square frame by materials such as square tubes. Two pairs of push plates 15 are symmetrically arranged on the frame 10 along the center of the frame 10, and a push plate driving mechanism 14 for driving the push plates 15 to move is provided on the frame 10, that is, a horizontal push plate 15 is arranged on the inner side of each side of the frame 10, and a push plate driving mechanism 14 for driving the push plate 15 to move is respectively arranged at a corresponding position on each side. The push plate driving mechanism 14 of this embodiment is an oil cylinder, one end of the oil cylinder is connected to the push plate 15, and the other end is connected to the frame 10.

[0040] In this embodiment, in order to ensure the accuracy of the moving direction of the push plate 15, a guide seat 12 is fixedly installed on the edge of the frame 10 corresponding to each push plate 15, and a guide rod 13 is installed on the guide seat 12, one end of the guide rod 13 passes through the guide seat 12 to connect the push plate 15.

[0041] Corresponding to the square structure of the frame 10, a sprocket 7 is respectively provided on the cross beam 5 above the four corners of the frame 10, that is, a group of sprockets 7 is respectively provided on the two parallel cross bars of the cross beam 5, and each sprocket 7 passes through a chain 8 separately, one end of the chain 8 is connected to the end of the lifting rod 3, and the other end is connected to a corner of the frame 10, and the two chains 8 corresponding to the same group of sprockets 7 are connected to the same end of the lifting rod 3.

[0042] In addition, in order to ensure the consistent movement of each chain 7 and avoid the frame 10 from tilting during the lifting process and affecting the alignment accuracy, this embodiment has a synchronous wheel 16 on the two parallel crossbars of the crossbeam 5, and the chains 8 of a group of sprockets 7 on the corresponding crossbars pass through the corresponding synchronous wheels 16 respectively. The two synchronous wheels 16 are connected by a synchronous shaft 6, and the axial direction of the synchronous shaft 6 is perpendicular to the moving direction of the chain 8. The two synchronous wheels 16 are kept in synchronous rotation by the synchronous shaft 6, so that the movement consistency of the four chains 8 passing through the synchronous wheels 16 can be ensured. At the same time, the edge of the frame 10 is equipped with a guide wheel 11 that fits the frame, which can ensure that the alignment component 9 does not shake too much during the lifting process, thereby improving the alignment accuracy of the blocks.

[0043] like Figure 3 As shown, when the device starts working, the alignment assembly 9 is at the highest position, and the conveying device conveys the block stacking layer to the position between the four push plates 15 just below the alignment assembly 9. At this time, the lifting mechanism 2 extends, raising the lifting rod 3, driving the alignment assembly 9 to descend. Figure 4 As shown in FIG. 1 , when the push plate 15 of the alignment assembly 9 is lowered to the staggered height of the upper layer of the block stack, the lifting mechanism 2 stops. At this time, the push plate driving mechanism 14 is activated to push the staggered blanks toward the inner side of the frame 10 and move toward the center, so that the upper layer of the block stack is finally maintained as shown in FIG. Figure 5 The four vertical planes shown in the figure complete the alignment work. After the alignment is completed, the lifting mechanism 2 is retracted, pulling the alignment assembly 8 back to the initial position.

[0044] In summary, the present embodiment is a device for aligning the staggered joints of a high-level concrete block stack. By lifting and aligning the assembly 9, the staggered joints of the high-level concrete block stack can be aligned, thereby ensuring the subsequent packaging effect of the high-level concrete block stack. In particular, the traditional method of directly setting a lifting mechanism above the frame, because the lifting mechanism such as an oil cylinder, an air cylinder, etc. itself needs to occupy a certain space, it is difficult for the lifting mechanism to have a sufficient lifting stroke within a certain installation space. The lifting assembly of the present embodiment uses the lifting and lowering of the lifting rod 3 to drive the chain 8 to move, and further drives the alignment assembly 9 to lift and lower through the sprocket 7 above the frame. Compared with the traditional method, the installation space of the lifting mechanism is transferred to the side flush with the frame, which effectively reduces the space occupied in the height direction of the device, that is, within a certain installation space, it has a larger lifting range, so that the alignment assembly can also perform normal alignment work for the bottom staggered joints of the high-level stack, and this installation structure enables the device to be directly installed above a block conveying device such as a chain machine, thereby ensuring the normal operation of the packaging line.
