Description

Technical Field

[0001] This utility model belongs to the field of autoclaved aerated concrete block technology, specifically relating to a device for correcting the verticality of autoclaved aerated concrete block stacking. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a type of lightweight, porous wall material made primarily from cement, lime, and sand, with the addition of a suitable amount of foaming agent. The mixture is stirred with water to form a slurry, poured to expand and form a blank, and then cut and trimmed to specific dimensions before being placed in an autoclave for curing under high temperature and high pressure.

[0003] The alignment process is crucial during the stacking of blocks. This is because blocks are susceptible to positional deviations due to various factors during transportation, handling, and initial stacking. If left unchecked, this will not only affect the neatness of the stack but may also lead to a risk of collapse as the stack height increases due to uneven stress between blocks. This could threaten the safety of workers, damage the blocks, and reduce the convenience and quality of subsequent construction. Therefore, alignment is essential to ensure that each layer of blocks is in the accurate position, laying the foundation for stable stacking.

[0004] Currently, the industry mainly relies on manual correction for block stacking, supplemented by simple mechanical tools. However, this type of correction method depends too much on human experience, which is not only slow and difficult to adapt to the needs of large-scale, high-efficiency block stacking, but also makes it difficult to control the force and precision of manual operation, which can easily lead to inadequate or over-correction, and cannot guarantee the consistency of correction. Utility Model Content

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3This utility model provides a device for correcting the verticality of autoclaved aerated concrete (AAC) block stacks. It includes a mobile vehicle body 1, with a correction component 2 at the front end of the mobile vehicle body 1. The correction component 2 includes a movable slide groove 201 at the front end of the mobile vehicle body 1. A bidirectional lead screw 202 is rotatably connected to the inside of the movable slide groove 201 via bearings. The side surfaces at both ends of the bidirectional lead screw 202 are provided with threads in opposite directions. Limiting slide grooves 203 are provided at the front end of the mobile vehicle body 1, located on the upper and lower sides of the movable slide groove 201. The limiting slide grooves 203 limit the movement of movable sliders 204, improving the stability and safety of the movable sliders 204. Movable sliders 204 are slidably connected to the inside of the movable slide groove 201 in a left-right symmetrical arrangement. Each movable slider 204 has a threaded hole 205 inside, with the threaded holes 205 reciprocating in opposite directions to the two ends of the bidirectional lead screw 202. With threaded connections, each of the two movable sliders 204 has a correction rod 206 fixedly connected to one end away from the movable slide groove 201. Limiting sliders 207 are fixedly connected to the side surfaces of the correction rods 206 and to the upper and lower ends of the movable sliders 204. Rubber pads 208 are fixedly connected to the sides of the correction rods 206 that are close to each other. The rubber pads 208 increase friction with the block and also protect the correction rods 206 and the block. A stepper motor 209 is fixedly installed on the right side of the movable vehicle body 1. Both movable sliders 204 are threadedly connected to the bidirectional lead screw 202 through threaded holes 205. The limiting sliders 207 are slidably connected inside the limiting slide groove 203, and both the limiting sliders 207 and the limiting slide groove 203 are T-shaped. The drive end of the stepper motor 209 is connected to the bidirectional lead screw 202 via a coupling.

[0022] The setting of the correction component 2 is achieved by starting the stepper motor 209, which drives the bidirectional lead screw 202 to rotate around the bearing through the coupling. At the same time, since the two movable sliders 204 are threadedly connected to the bidirectional lead screw 202 through the internal threaded holes 205, and the limiting slider 207 is slidably connected in the limiting groove 203, the rotation of the bidirectional lead screw 202 is converted into the linear movement of the movable sliders 204 along the movable groove 201. The two movable sliders 204 will move in opposite directions or in the opposite direction due to the thread characteristics of the bidirectional lead screw 202. Therefore, when the movable sliders 204 move, they will drive the fixed correction rod 206 to move synchronously. When the correction rod 206 contacts the stack of autoclaved aerated concrete blocks, the rubber pad 208 fixed on its side surface will first contact the blocks, and then the verticality of the block stack will be corrected by the continuous movement of the correction rod 206. This invention uses a stepper motor 209 to drive a bidirectional lead screw 202, which can precisely control the moving distance and speed of the two moving sliders 204 and the correction rod 206, ensuring the accuracy of the correction process and avoiding errors caused by manual correction. This not only improves the speed of block stacking correction for workers, but also effectively improves the safety and stability of block stacking.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the adjustment component 3 is provided inside the correction rod 206. The adjustment component 3 includes a hydraulic cylinder 301 that is symmetrically distributed and fixedly installed inside the correction rod 206. The telescopic end of the hydraulic cylinder 301 is fixedly connected to a telescopic block 302. A rotating groove 303 is provided on one side of the telescopic block 302. A roller 304 is rotatably connected inside the rotating groove 303 through a bearing. A rubber ring is provided on the side surface of the roller 304. An oil supply pipe 305 is fixedly connected to the outside of the movable slider 204. The oil supply pipe 305 is made of rubber hose and passes through the inside of the movable slider 204 and is connected to the hydraulic cylinder 301.

[0024] The adjustment component 3 is configured to supply or extract hydraulic oil to the hydraulic cylinder 301 via the oil supply pipe 305, thereby controlling the extension and retraction of the telescopic end of the hydraulic cylinder 301. The telescopic block 302 at the telescopic end of the hydraulic cylinder 301 moves synchronously with the telescopic end. When the telescopic block 302 moves to the appropriate position, the roller 304, which is rotatably connected to the bearing inside the rotating groove 303 on one side, will contact the side of the autoclaved aerated concrete block stack. During the process of the correction component 2 driving the correction rod 206 to move and correct the verticality, the roller 304 will rotate around the bearing in the rotating groove 303, reducing the friction between the correction rod 206 and the block stack, and can correct blocks that are high or in contact with the block. The adjustment component 3 of this utility model is hydraulically driven by the hydraulic cylinder 301 through the oil supply pipe 305. It can flexibly adjust the position of the telescopic block 302 and the roller 304. The contact position of the roller 304 can be adjusted according to the height of the block stacking, ensuring that the roller 304 can play an effective role in the correction process of block stacking at different heights, and improving the adaptability of the device to block stacking at different heights.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, a control panel 4 is fixedly installed on the top of the mobile vehicle 1, and casters 5 are fixedly installed in a rectangular array at the bottom of the mobile vehicle 1. A placement slot 6 is opened at the rear end of the mobile vehicle 1. A counterweight 7 is placed inside the placement slot 6, and a door 8 is hinged to the opening of the placement slot 6. The combination design of the placement slot 6, the counterweight 7, and the door 8 can increase or decrease the number of counterweights 7 according to actual correction needs, flexibly adjust the overall weight of the device, ensure that the device remains stable under different correction forces, avoid the risk of tipping over, and ensure the safety of operators. A pusher 9 is fixedly connected to the rear end of the mobile vehicle 1 and above the placement slot 6. The cooperation between the casters 5 and the pusher 9 gives the device good mobility, and operators can move the device to the required position without strenuous carrying. It is suitable for block stacking correction work in different workshops and areas, improving work convenience and efficiency.

[0026] Working principle and usage process of this utility model:

[0027] When using the autoclaved aerated concrete block stack verticality correction device, the staff first open the hinged door 8 at the opening of the placement slot 6 at the rear of the mobile vehicle 1 according to the weight of the stack of blocks to be corrected and the correction requirements, and place an appropriate number of counterweights 7 into the placement slot 6. Then close the door 8 and flexibly adjust the overall weight of the device by adding or removing counterweights 7 to ensure the stability of the device during the subsequent correction process and avoid the risk of tipping over.

[0028] Next, the staff member holds the push handle 9 at the rear of the mobile vehicle 1 and uses the universal wheels 5 at the bottom of the mobile vehicle 1 to push the device to the position to be calibrated where the autoclaved aerated concrete blocks are stacked. After reaching the position, the staff member inputs the calibration parameters through the control panel 4 and starts the calibration program. Then, the stepper motor 209 starts, causing its transmission end to drive the bidirectional lead screw 202 to rotate around the bearing. Since the two moving sliders 204 are threadedly connected to the bidirectional lead screw 202 through the threaded holes 205 that are adapted to the reverse threads of the bidirectional lead screw 202, and the limiting slider 207 is slidably connected inside the limiting groove 203, the rotation of the bidirectional lead screw 202 is converted into the linear movement of the moving sliders 204 along the moving groove 201, and the two moving sliders 204 move towards each other. When the moving sliders 204 move, they drive the fixedly connected calibration rod 206 to move synchronously, thereby realizing the calibration of the blocks.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
