Description

Technical Field

[0001] The utility model relates to the field of assembled building construction, in particular to an assembled building construction auxiliary device. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods. During the construction process, a plurality of grouting holes and grouting holes are opened in the prefabricated wall panels. After the wall panels are installed, workers need to hold the grouting pipe to pour concrete into the wall panels. However, due to the high pressure in the grouting pipe during grouting, it becomes more difficult for workers to hold, which increases the difficulty of grouting and may also cause the grouting pipe to detach from the grouting hole. Therefore, an auxiliary device for grouting construction of prefabricated concrete buildings is needed.

[0003] After searching, the Chinese patent announcement number CN218758835U discloses an auxiliary device for grouting construction of assembled concrete buildings. When in use, this patent does not require manual holding of the grouting pipe. The grouting pipe can be placed in the support pipe and the limit mechanism can be manually adjusted to fix the grouting pipe. At the same time, the limit plate can be driven to move through the support assembly to fix the grouting pipe. It can also prevent the grouting pipe from separating from the grouting hole to ensure the effectiveness of the grouting.

[0004] However, the above patent clamps and fixes the grouting pipe by elastic parts. When the grouting pipe is suddenly sprayed, the grouting pipe may become loose and unstable due to the influence of recoil, which affects the effect of subsequent grouting. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1-Figure 6As shown, an assembled building construction auxiliary device includes a base plate 1, and the four bottom corners of the base plate 1 are provided with self-locking walking wheels. The top of the base plate 1 is connected to a lifting plate 2 through a lifting mechanism. The lifting mechanism includes a screw rod 301 rotatably connected to the top of the base plate 1, a guide rod 302 is fixedly connected to the top of the base plate 1, and a cross plate 303 is fixedly connected to the top of the guide rod 302. The screw rod 301 and the cross plate 303 are rotatably connected. The top of the cross plate 303 is bolted with a rotating motor 304, and the output end of the rotating motor 304 is connected to the screw rod 301 through a coupling. The lifting plate 2 is threadedly connected to the screw rod 301, and the lifting plate 2 is slidably connected to the guide rod 302. The rotating motor 304 is started, and the rotating motor 304 drives the screw rod 301 to rotate, and the screw rod 301 drives the lifting plate 2 to move along the guide rod 302, so as to facilitate the adjustment of the height of the grouting pipe.

[0027] The bottom bolts of the lifting plate 2 are connected with a stepper motor 7. A through hole is opened on the top of the bottom plate 1. The stepper motor 7 can extend into the through hole to prevent the stepper motor 7 from affecting the lifting height of the lifting plate 2. The output end of the stepper motor 7 is fixedly connected with the mounting plate 4. When the stepper motor 7 is started, the stepper motor 7 drives the mounting plate 4 to drive the grouting pipe to swing back and forth within a certain range, thereby improving the grouting effect. Whether the grouting pipe needs to swing is determined according to construction requirements.

[0028] A clamping mechanism is provided on the top of the mounting plate 4, and the clamping mechanism includes a mounting seat 501 bolted to the top of the mounting plate 4, a turntable 502 is rotatably connected in the mounting seat 501, a fixed plate 503 is fixedly connected to the front side of the mounting seat 501, a first limiting groove 504 is provided on the front side of the turntable 502, a second limiting groove 505 is provided on the front side of the fixed plate 503, the first limiting groove 504 is arc-shaped, and the second limiting groove 505 is linear, a connecting rod 506 is slidably connected in the first limiting groove 504, the front side of the connecting rod 506 passes through the second limiting groove 505 and is fixedly connected to a clamping plate 507, and a mounting groove is provided inside the clamping plate 507. A fixing rod 508 is fixedly connected in the groove, and a cam 509 is rotatably connected to the fixing rod 508. A torsion spring for resetting is connected between the cam 509 and the fixing rod 508. Under initial conditions, the distance between the edge of the leaking part of the cam 509 and the fixing rod 508 is the smallest. When the grouting pipe moves backward under the recoil force, the cam 509 rotates under the action of friction, so that the distance between the outer edge of the cam 509 and the fixing rod 508 gradually increases, and the cam 509 provides a resisting force on the grouting pipe. The greater the distance the grouting pipe moves, the greater the resisting force of the cam 509, thereby making the grouting pipe more stable when it is suddenly discharged and subjected to a large recoil force.

[0029] Two groups of clamping mechanisms are arranged on the top of the mounting plate 4, and the two groups of clamping mechanisms are arranged front and back.

[0030] A power mechanism is provided on one side of the clamping mechanism, and the power mechanism is used to drive the turntable 502 to rotate. The power mechanism includes a gear ring 601 welded to the outer wall of the turntable 502, and the top middle bolt of the mounting plate 4 is connected to the support seat 602, and the top bolt of the support seat 602 is connected to the dual-axis motor 603, and the output end of the dual-axis motor 603 is fixedly connected to a gear 604, and the gear 604 is meshed with the gear ring 601. The dual-axis motor 603 is a brake motor to ensure that the gear 604 will not rotate after the dual-axis motor 603 stops.

[0031] Working principle: The grouting pipe is passed between the rotating disk 502 and the fixed disk 503, and the double-axis motor 603 is started. The double-axis motor 603 drives the gear 604 to rotate, and the gear 604 meshes with the gear ring 601, thereby driving the gear ring 601 to drive the rotating disk 502 to rotate. When the rotating disk 502 rotates, it will drive multiple groups of connecting rods 506 to move synchronously in the direction of approaching each other under the limitation of the first limiting groove 504 and the second limiting groove 505, so as to clamp and fix the grouting pipe to prevent the grouting pipe from loosening and becoming unstable when subjected to a large recoil force, thereby affecting the effect of subsequent grouting. When the grouting pipe moves backward under the recoil force, the convex The wheel 509 rotates under the action of friction, so that the distance between the outer edge of the cam 509 and the fixed rod 508 gradually increases, and the cam 509 provides a resisting force on the grouting pipe. The greater the distance the grouting pipe moves, the greater the resisting force of the cam 509, so that the grouting pipe is more stable when it is suddenly discharged and subjected to a large recoil force. The rotating motor 304 is started, and the rotating motor 304 drives the screw rod 301 to rotate, and the screw rod 301 drives the lifting plate 2 to move along the guide rod 302, so as to facilitate the adjustment of the height of the grouting pipe. The stepper motor 7 is started, and the stepper motor 7 drives the mounting plate 4 to drive the grouting pipe to swing back and forth, thereby improving the grouting effect.
