Description

Technical Field

[0001] The invention relates to the technical field of building wall moulds, in particular to a mould for accurately controlling the thickness of masonry mortar. Background Art

[0002] Mortar walls are the most common construction method in the construction industry. Mortar mold wall construction can speed up construction. Compared with traditional wall construction, the use of mortar molds can reduce construction time and improve project progress. Mortar molds can be reused, which reduces production costs. In addition, due to the strength and durability of mortar walls, subsequent maintenance and repair costs are reduced, which is cost-effective. When using molds, the mortar thickness can be controlled, so that the mortar is evenly filled between bricks, which makes each brick more tightly connected, making the wall more complete and solid.

[0003] However, in the existing wall-building process, mortar is generally added by manual mortar laying.

[0023] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0024] 1. An automatic grouting component is provided. By controlling the servo motor to rotate in the reverse direction, the connecting rod is driven to rotate toward the side of the main clamping mold, and the grouting pipe fixing ring drives the grouting pipe to swing toward the side of the main clamping mold. After a period of time, the servo motor is started again to rotate forward to swing the grouting pipe toward the auxiliary clamping mold again. The servo motor is repeatedly controlled to rotate forward and reverse, so that the grouting pipe can be controlled to swing back and forth regularly. Under the action of the limit springs on both sides, the rotation of the rotating rod will be subject to a certain resistance, thereby preventing the swing amplitude from being large due to the inertia of the grouting pipe, thereby controlling the outflow and laying range of the mortar to the middle position of the top of the brick. If the wall is thick, the servo motor can be repeatedly controlled to rotate forward and reverse, so that the grouting pipe can be controlled to swing back and forth regularly. At this time, the mortar can be laid evenly and at a uniform speed to the top of the brick. At the middle position, after placing the new bricks on the top of the mortar, it can be ensured that the spread mortar will not overflow to the outside of the bricks, and after the mortar laying of a part of the wall is completed, the two driving rollers are controlled to rotate at the same time to drive the main clamping mold and the auxiliary clamping mold to move on the top of the wall bricks toward the front sliding rod. At this time, the main clamping mold and the auxiliary clamping mold will move at a uniform speed on the top of the wall bricks, and during the movement, the grouting pipe will be controlled by the connecting rod to evenly lay the mortar on the top of the entire wall, thereby ensuring that the mortar laying thickness of the entire wall is uniform, further saving materials while ensuring the strength of the wall without manual grouting pipe control, and can accurately control the grouting angle and grouting amount while reducing manual errors and fatigue. The automated masonry grouting process improves work efficiency while ensuring project quality.

[0025] 2. It is equipped with a driving gear, a directional seat, a directional cylinder, a rear end slide rod, a driven tooth, a length electromagnet, a positioning iron sheet, a front end slide rod, a limit seat and a connecting electromagnet. When it encounters the longitudinal reinforcement inside the wall, it can control the continuous movement and fixation of the rear end slide rod and the front end slide rod, and cooperate with the connecting rod to fix the relative positions of the main clamping mold and the auxiliary clamping mold, thereby ensuring that the main clamping mold and the auxiliary clamping mold can evenly lay mortar on the masonry while passing through the longitudinal reinforcement, thereby automatically laying the mortar evenly on the top of the entire wall, further improving the applicability of the grouting template, and thus improving work efficiency.

[0026] 3. A scraper assembly is provided. Due to the presence of multiple scroll return springs, each time the main clamping mold and the auxiliary clamping mold move forward a certain distance, the scraper will rebound and scrape once, so that the mortar can be continuously scraped to the inside of the recovery box. The mortar will slide from the guide inclined plate to the inside of the guide trough, and then fall to the inside of the clamping trough plate at the bottom. After a period of work, the clamping screw inside the clamping threaded hole can be loosened to release the restriction of the clamping screw on the guide trough. The clamping trough plate can then be replaced in time, and the collected mortar can then be added back to the inside of the pump to prevent the recycled mortar from solidifying and wasting, saving resources and reducing waste in construction projects.

[0027] To sum up, when encountering the longitudinal steel bars inside the wall, the rear end sliding rod and the front end sliding rod can be controlled to move and fix continuously, and the connecting rod can be used to fix the relative positions of the main clamping mold and the auxiliary clamping mold, so as to ensure that the main clamping mold and the auxiliary clamping mold can evenly grout the masonry while passing through the longitudinal steel bars. The scraper will be blocked by the steel bars when passing through the longitudinal steel bars. After the main clamping mold and the auxiliary clamping mold have completely passed through the steel bars, the scraper will be reset under the action of the scroll return spring, thereby continuing to scrape off excess mortar, further improving the applicability of the grouting template, and thus improving work efficiency.

The outer diameter of the fixed support ring 304 is equal to the inner diameter of the rotating sleeve 305, which is convenient for replacing the clamping groove plate 312.

[0053] The working principle and use process of the present invention are as follows: First, the operator places the main clamping mold 1 and the auxiliary clamping mold 201 at the top ends of the bricks to be laid. At this time, the driving roller 205 and the driven roller 208 on the top of the main clamping mold 1 and the auxiliary clamping mold 201 are supported at the top position of the bricks, and the operator pushes the main clamping mold 1 and the auxiliary clamping mold 201 at the same time according to the thickness of the wall bricks, thereby squeezing the main clamping mold 1 and the auxiliary clamping mold 201 in the same direction, and then the main clamping mold 1 and the auxiliary clamping mold 201 are installed side by side. The lateral support wheels 210 inside the groove 209 will also fit on both sides of the wall brick, thereby clamping the main clamping mold 1 and the auxiliary clamping mold 201 to the top of the wall brick. Then the operator controls all the length electromagnets 218 to turn on at the same time. At this time, the length electromagnets 218 will be attracted to the positioning iron pieces 219 outside the rear end slide bar 216 and the front end slide bar 220. At this time, both ends of the main clamping mold 1 and the auxiliary clamping mold 201 are fixed by the rear end slide bar 216 and the front end slide bar 220, so the main clamping mold 1 and the auxiliary clamping mold 201 will be fixed;

[0054] Next, the operator inserts the external grouting pipe into the inner position of the grouting pipe fixing ring 231, and then loosens the threaded barrel 229 through the handle 232. At this time, the grip of the handle 232 and the anti-slip plate 228 on the connecting rod 225 is released. Then, the servo motor 222 is controlled to rotate, and the connecting rod 225 is rotated to be close to the top of the auxiliary clamping mold 201.

[0055] Then, the limiting sleeve 227 is slid inside the length adjustment groove 226 to slide it to the end close to the auxiliary clamping mold 201. Then, the operator rotates the handle 232 again. At this time, the connecting rod 225 can be clamped again by the handle 232 and the anti-slip sheet 228. At this time, the position of the limiting sleeve 227 can be fixed;

[0056] Then the operator opens the control valve of the external grouting pipe. At this time, a large amount of mortar will enter the middle of the main clamping mold 1 and the auxiliary clamping mold 201 through the grouting pipe, and then be laid on the top of the wall brick. Then the operator controls the servo motor 222 to rotate in the opposite direction, thereby driving the connecting rod 225 to rotate toward the side of the main clamping mold 1, and then drives the grouting pipe to swing toward the side of the main clamping mold 1 through the grouting pipe fixing ring 231. After a period of time, the servo motor 222 is started again to rotate forward, and the grouting pipe is swung toward the auxiliary clamping mold 201 again. When the connecting rod 225 rotates, it will drive the rotating rod 223 to rotate on the inner side of the limit seat 221. Under the action of the limit springs 224 on both sides, the rotation of the rotating rod 223 will be subject to a certain resistance, thereby preventing the swing amplitude from being large due to the inertia of the grouting pipe, thereby controlling the outflow and laying range of the mortar to the middle position of the top of the brick, and if the wall is thicker, the servo motor 222 can be repeatedly controlled to rotate forward and reverse, so that The grouting pipe is controlled to swing back and forth regularly. At this time, the mortar can be evenly and uniformly laid to the middle position of the top of the brick. After the new brick is placed on the top of the mortar, it can be ensured that the spread mortar will not overflow to the outside of the brick. After the grouting of a part of the wall is completed, the power motor 207 inside the drive motor seat 206 is controlled to start. At this time, the drive rod 204 can be driven by the power motor 207 to rotate on the inner side of the drag reduction bearing 203, and then the drive rod 204 can drive the drive roller 205 to rotate. When the two drive rollers 205 rotate at the same time, the main clamping mold 1 and the auxiliary clamping mold 201 will move at the top of the wall brick toward the front end slide rod 220. At this time, the main clamping mold 1 and the auxiliary clamping mold 201 will move at a uniform speed on the top of the wall brick, and during the movement, the grouting pipe will be controlled by the connecting rod 225 to evenly lay the mortar on the top of the entire wall, thereby ensuring that the mortar laying thickness of the entire wall is uniform, further saving materials while ensuring the wall strength.

[0057] When the main clamping mold 1 and the auxiliary clamping mold 201 are continuously moving and move to one side of the longitudinal steel bars inside the wall, the operator controls the two power motors 207 to stop working and closes the control valve of the external grouting pipe. After the residual mortar inside the grouting pipe stops flowing, the main clamping mold 1 and the auxiliary clamping mold 201 continue to be driven to move toward the longitudinal steel bars. At this time, the servo motor 222 is controlled to rotate and the connecting rod 225 is rotated again to fit the top position of the auxiliary clamping mold 201. At the same time, the connecting electromagnet 233 is turned on so that the connecting rod 225 can be magnetically fixed to the top of the auxiliary clamping mold 201. At this time, the relative positions of the main clamping mold 1 and the auxiliary clamping mold 201 can be fixed from the middle through the limit seat 221 and the connecting rod 225. Immediately after fixing, the three-phase motor 212 near the front sliding rod 220 is turned on and the two length electromagnets 218 at one end of the front sliding rod 220 are closed. The driving gear 213 is driven to rotate by the three-phase motor 212, and because the driving gear 213 passes through The movable teeth 217 are engaged with the front end slide bar 220, so the front end slide bar 220 can be driven by the driving gear 213 to slide inside the directional cylinder 215 and the directional seat 214, thereby controlling the front end slide bar 220 to slide in the direction of the main clamping mold 1. At this time, one end of the front end slide bar 220 will slide out of the directional cylinder 215 at the top of the auxiliary clamping mold 201. When the front end slide bar 220 completely slides to one end of the main clamping mold 1, the main clamping mold 1 and the auxiliary clamping mold 201 are controlled to continue to move in the direction of the longitudinal steel bars. Move, at this time the longitudinal steel bar will enter the middle position of the main clamping mold 1 and the auxiliary clamping mold 201. When the longitudinal steel bar has completely passed the front end slide bar 220, the front end slide bar 220 can be controlled to slide again into the inner side of the directional cylinder 215 at the top of the auxiliary clamping mold 201. At this time, the two length electromagnets 218 at one end of the front end slide bar 220 are turned on again, so that the relative positions of the main clamping mold 1 and the auxiliary clamping mold 201 can be fixed again by the front end slide bar 220 and the length electromagnet 218;

[0058] Then, the servo motor 222 is turned on so that the connecting rod 225 can be lifted up again. At this time, the connecting rod 225 can be rotated to a position perpendicular to the main clamping mold 1, and the grouting pipe can also be moved to the top of the main clamping mold 1. Then, the main clamping mold 1 and the auxiliary clamping mold 201 are continued to be moved, and the longitudinal steel bar will move to the space between the connecting rod 225 and the rear end slide bar 216. Then, the connecting rod 225 is controlled to be re-tightened and fixed to the top of the connecting electromagnet 233, and then the three-phase motor 212 on one side of the rear end slide bar 216 is turned on, so that the rear end slide bar 216 can be completely moved to one side of the main clamping mold 1. The main clamping mold 1 and the auxiliary clamping mold 201 are moved forward, and the longitudinal steel bars are moved out from the rear ends of the main clamping mold 1 and the auxiliary clamping mold 201. The rear end slide bar 216 is then slid again into the directional cylinder 215 on the top of the auxiliary clamping mold 201. All the length electromagnets 218 are then turned on to fix the relative positions of the main clamping mold 1 and the auxiliary clamping mold 201 again. The main clamping mold 1 and the auxiliary clamping mold 201 are then moved in the direction in which grouting is required. The grouting pipe is then swung by the rotation of the servo motor 222 to evenly spread the mortar on the top of the brick.

[0059] Finally, in the process of laying mortar, it is difficult for the external grouting pump to unify the flow rate when encountering mortars of different densities. At this time, some mortars will flow too fast, resulting in a thicker mortar thickness. At this time, after the main clamping mold 1 and the auxiliary clamping mold 201 pass through the rear support rod 307, they will also pass through the wall bricks. At this time, the mortar can be scraped off by the scraper 308 at the bottom of the support rod 307, and due to the existence of friction during scraping, the unfixed end of the support rod 307 will slide backwards, and the scraped mortar will flow backwards along the scraper 308, thereby flowing The scraper 308 is moved to the inner side of the recovery box 309 for recovery, and due to the presence of multiple scroll return springs 306, each time the main clamping mold 1 and the auxiliary clamping mold 201 move forward a certain distance, the scraper 308 will rebound and scrape once, so that the excess mortar can be continuously scraped to the inner side of the recovery box 309, and when passing through the longitudinal steel bars, the scraper 308 will be blocked by the steel bars. After the main clamping mold 1 and the auxiliary clamping mold 201 have completely passed through the steel bars, the scraper 308 will be reset under the action of the scroll return spring 306, thereby continuing to scrape off the excess mortar;

[0060] Finally, after the excess mortar is scraped off, it will fall to the inside of the recovery box 309, and then the mortar will slide from the guide inclined plate 310 to the inside of the guide trough 311, and then fall to the inside of the bottom clamping groove plate 312. After a period of work, the clamping screw 315 inside the clamping threaded hole 314 can be loosened, thereby releasing the restriction of the clamping screw 315 on the guide trough 311, and then the clamping groove plate 312 can be replaced in time, and then the collected mortar can be added back to the inside of the pump to prevent the recycled mortar from solidifying and wasting, saving resources and reducing waste in construction projects.
