Abstract

The present invention discloses an auxiliary rubber and plastic device for ALC board installation construction used in building construction, comprising a mobile chassis, a fixed limit frame assembly fixed on one side of the upper end surface of the mobile chassis, and a rotating limit frame assembly rotatably matched on the other side. The lever lifting assembly provided by the present invention limits the two end surfaces of the ALC board through the fixed limit frame assembly and the rotating limit frame assembly. The lifting legs are clamped into the bottom of the ALC board by adjusting the position of the lever lifting assembly, and the ALC board is synchronously lifted by the lever assemblies on both sides by using a plurality of pulleys and a power mechanism, so that the ALC board is supported by the rolling wheel group and the supporting balls to move. In this way, when the operator adjusts the position of the ALC board, the ALC board moves as a whole, and the ALC board is moved smoothly as a whole by adjusting the mobile chassis, so that the adhesive is prevented from being repeatedly loosened due to the use of a crowbar to move the ALC board.

Description

Technical Field

[0001] The invention belongs to the technical field of ALC board installation devices, and particularly relates to a rubber and plastic auxiliary device for ALC board installation construction in building construction. Background Technique

[0002] The ALC board is a multi-porous concrete formed board mainly made of fly ash (or silica sand), cement, lime, etc., and is formed through high-pressure steam curing. It is a new type of building material with excellent performance. The ALC board has good sound insulation, fire resistance, low cost, and convenient installation, and is widely used in the construction of indoor wall panels.

[0003] The ALC board is a precast board. During construction, operators fix and assemble the prepared ALC boards one by one to form a complete internal partition wall. Currently, when installing the ALC board, it is mostly the cooperation of multiple operators to move the ALC board to the designated position, erect it for installation, and use tools such as crowbars to gradually adjust the position. However, there are relatively large safety hazards in this process. Although the ALC board is a lightweight board, its large volume still has a relatively large weight. Therefore, during the movement process, it is necessary to always pay attention to preventing it from tipping over and injuring operators. In addition, when assembling the ALC board, a special adhesive needs to be applied for fixation. When using a crowbar to adjust the position of the ALC board little by little, the already bonded adhesive is likely to loosen again, resulting in a decrease in the bonding effect of the adhesive compared to the first bonding fixation, and further leading to a reduction in the fastening of the ALC board assembly. Therefore, it is necessary to invent a rubber and plastic auxiliary device for ALC board installation construction in building construction. Summary of the Invention

[0004] The purpose of the invention is to provide a rubber and plastic auxiliary device for ALC board installation construction in building construction to solve the technical problems that when installing the ALC board, the position cannot be adjusted smoothly, resulting in multiple cracks in the adhesive bonding and a reduction in the fastening after the ALC board is adhesively fixed, and there are relatively large safety hazards when multiple operators are required to cooperate in hoisting and lifting during the installation of the ALC board.

In this way, when the operator adjusts the position of the ALC board, the ALC board moves as a whole, and the ALC board is moved smoothly as a whole by adjusting the moving chassis, thereby avoiding the situation where the adhesive is repeatedly loosened due to the use of a crowbar to move the ALC board.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] As shown in Figures 1-7 Fig. [8], a rubber and plastic auxiliary device for the installation and construction of ALC boards for building construction includes a mobile chassis 6. One side of the upper end surface of the mobile chassis 6 is fixedly provided with a fixed limit frame assembly 1, and the other side is rotatably fitted with a rotating limit frame assembly 2. Lever lifting assemblies 3 are fitted on both the fixed limit frame assembly 1 and the rotating limit frame assembly 2. A hoisting assembly 4 is installed on the fixed limit frame assembly 1. A power mechanism 5 is provided on the mobile chassis 6, and the power mechanism 5 and the hoisting assembly 4 are a matching mechanism;

[0031] As an embodiment of the present invention, as shown in Figures 2-3 Fig.

[13] , the lever lifting assembly 3 includes a lifting plate frame 31 that is respectively slidably fitted on the fixed limit frame assembly 1 and the rotating limit frame assembly 2. The lever lifting assembly 3 is symmetrically arranged on both sides, so as to lift the ALC board 7 from both ends simultaneously. On both sides of one end surface of the lifting plate frame 31, a plurality of limit rod sleeves 32 are fixedly provided. The other end of the limit rod sleeve 32 is fixedly provided with an H-shaped plate 34. A waist-shaped hole is opened in the limit rod sleeve 32, and a lever component 33 is slidably fitted in the waist-shaped hole. Rectangular grooves are opened on both sides of the top end of the H-shaped plate 34, and a fixed rod sleeve 35 is slidably fitted in the rectangular grooves. One end of the fixed rod sleeve 35 is fixedly connected to the lever component 33, and the other end is equipped with a moving pulley 36. A plurality of fixed pulleys 37 are provided on the H-shaped plate 34. A winding pulley 38 is provided at the lower end of the lifting plate frame 31, and the moving pulley 36, the fixed pulley 37, and the winding pulley 38 are a matching mechanism. The moving pulley 36, the fixed pulley 37, and the winding pulley 38 are connected by a steel cable. One end of the steel cable is bolted to the lower position of the moving pulley 36 and fixed to the H-shaped plate 34. The steel cables symmetrically arranged at both ends of the H-shaped plate 34 are connected through a connecting ring and are jointly connected to the winding pulley 38.

[0032] During specific operation, the steel cable is synchronously wound by the winding pulley 38 provided on the fixed limit frame assembly 1 and the rotating limit frame assembly 2, so that a plurality of moving pulleys 36 are synchronously pulled and move downward, thereby driving the lever component 33 to simultaneously lift the ALC board 7, making the ALC board 7 leave the ground and facilitating the adjustment of the position.

[0033] As an embodiment of the present invention, as shown inFigures 3-4 As shown, the lever component 33 includes a sliding rod 331 slidably fitted in the waist-shaped hole. A lifting support foot 332 is hinged to the bottom of the sliding rod 331, and a retaining ring is provided at the top. A support spring is provided between the retaining ring and the upper end surface of the top limit rod sleeve 32. The support spring presses the retaining ring to keep the sliding rod 331 at the highest point under normal conditions. An articulated rod 334 is provided at the middle part of the lifting support foot 332, and the lifting support foot 332 is hinged to the bottom leg of the fixed limit frame assembly 1 through the articulated rod 334. A support ball 335 is provided at the bottom fulcrum of the lifting support foot 332, and a rolling wheel set 333 is fixed to one side of the support ball 335. When the lifting support foot 332 is lifted by the sliding rod 331, it tilts forward. The support ball 335 serves as the lever force application point of the lifting support foot 332, and the rolling wheel set 333 is the support structure for the movement of the ALC board 7;

[0034] During specific operation, adjust the position of the lever lifting assembly 3 so that the front end of the tilted lifting support foot 332 is inserted into the bottom of the ALC board 7. After both sides are adjusted in place, synchronously pull down the sliding rod 331 by using the winding pulley 38, so that the sliding rod 331 pries the ALC board 7 around the support ball 335 to lift the ALC board 7. At the same time, the rolling wheel set 333 provided at the lower end of the lifting support foot 332 touches the ground, thereby supporting the movement of the ALC board 7. In this way, when the operator installs the ALC board 7, it is possible to relatively easily adjust the position of the ALC board 7. Continuous clamping can facilitate the operator to observe and position at different distances, so as to perform rapid installation accurately without error. In addition, uniform force application can protect the ALC board 7 from being easily damaged and having defects during installation, making the installation operation of the ALC board 7 more standardized and the installation quality easier to control.

[0035] As an implementation manner of the present invention, as Figure 3 、 Figure 6 shown, a spline groove is provided at the central position of the winding pulley 38. Through the provided spline groove, the lever lifting assembly 3 and the hoisting assembly 4 share a transmission system by matching with the spline, which is convenient for the operator to operate uniformly.

[0036] As an implementation manner of the present invention, as Figure 2 、 Figure 5As shown in the figure, the fixed limit frame assembly 1 includes a fixed limit frame 11 fixed on the moving chassis 6. The bottom of the fixed limit frame assembly 1 is flush with the bottom of the moving chassis 6, and free balls for movement are provided at the bottom of both the fixed limit frame assembly 1 and the moving chassis 6. Above the fixed limit frame 11, a hoist support frame 12 is fixed. At the middle position of the fixed limit frame 11, a fixed mounting plate 13 is fixed. On the fixed mounting plate 13, there are multiple limit slide bars 14 for the sliding of the limit lifting plate frame 31. A sliding sleeve is fixed on the fixed limit frame 11, and the limit slide bars 14 are slidably fitted in the sliding sleeve. One end of the limit slide bars 14 is fixedly connected to the lifting plate frame 31, playing a role of limit support. On the fixed mounting plate 13, there is also an adjusting screw 15 for adjusting the position of the lifting plate frame 31. One end of the adjusting screw 15 is fixedly connected to the lifting plate frame 31. By rotating the adjusting screw 15, the position of the lifting plate frame 31 is adjusted, so that the lifting support feet 332 are inserted into the bottom of the ALC board 7. At the bottom of the end where the fixed limit frame 11 is fixed to the moving chassis 6, there is a first gear 16, and the first gear 16 and the power mechanism 5 are a matching mechanism.

[0037] As an embodiment of the present invention, as Figure 2 , Figure 5 and Figure 6 shown in the figure, the rotating limit frame assembly 2 includes a rotating seat 22 rotatably fitted on the moving chassis 6. A rotating limit frame 21 is fitted on the rotating seat 22. At one end of the bottom of the rotating limit frame 21, there is a fixed pin 23 for fixing the position of the rotating limit frame 21. On one side of the fixed pin 23, a second gear 24 is rotatably fitted, and a polygonal rod pin 25 is provided between the first gear 16 and the second gear 24. At the middle position of the rotating limit frame 21, a lifting plate frame 31 is also fixed. And on the lifting plate frame 31 fixed by the rotating limit frame 21, there is a sprocket. The sprocket is key-connected to the winding pulley 38 on this side, and the sprocket is chain-connected to the second gear 24. At the middle positions of the fixed limit frame 11 and the rotating limit frame 21, the same support mechanism, that is, the lifting plate frame 31, is fixed. The sprocket provided outside the lifting plate frame 31 at the end of the rotating limit frame 21 is fixedly key-connected to the winding pulley 38. The polygonal rod pin 25 is detachable, and the two-end lever lifting assembly 3 realizes synchronous movement through the polygonal rod pin 25.

[0038] During specific operation, remove the polygonal rod pin 25 and the fixing pin 23, rotate the rotation limiting frame assembly 2, and rotate it outward. Thus, when taking the ALC board 7, the whole device forms an L shape, approaches the stacked ALC boards 7 for handling, uses the fixing limiting frame assembly 1 and the moving chassis 6 as supports, and uses the hoisting assembly 4 to hoist the ALC board 7 to the installation position. Then, stand the ALC board 7 upright, adjust the position of the device, and then rotate the rotation limiting frame assembly 2 to make it parallel to the fixing limiting frame assembly 1. Install the fixing pin 23 and the polygonal rod pin 25 to fix the rotation limiting frame assembly 2, and the two-end lever lifting assembly 3 moves synchronously. By adjusting the adjusting screw 15 at both ends, the lifting feet 332 provided at the bottom of the two-end lever lifting assembly 3 are squeezed into the bottom of the ALC board 7. At the same time, the lifting plate frames 31 at both ends are close to the ALC board 7. Then, the power mechanism 5 drives the winding pulleys 38 at both ends to wind simultaneously, so that the multiple lifting feet 332 lift the ALC board 7 synchronously for installation operation.

[0039] As an embodiment of the present invention, as Figure 6 shown, a hollow frustum for accommodating the movement of the winding pulley 38 is provided on the fixed mounting plate 13, and the hollow frustum is fixedly welded to the fixed mounting plate 13. When adjusting the lifting plate frame 31, the extended winding pulley 38 is retracted into the hollow frustum.

[0040] As an embodiment of the present invention, as Figures 5-6 shown, the hoisting assembly 4 includes a fixed end cover 43 fixed at one end of the hollow frustum. One end of the fixed end cover 43 is rotatably fitted with a transmission gear 44 through a bearing. A hollow conical platform is integrally formed on the side wall of the transmission gear 44, and a spline hole is provided at the center position of the conical platform. A hoisting module 45 is provided outside the transmission gear 44, and the hoisting module 45 is fixed to the fixed limiting frame 11 through a support platform. The other end of the hoisting module 45 is rotatably fitted with the transmission gear 44. A drum is provided in the hoisting module 45. A limiting sleeve 46 is fixed at the end of the drum away from the transmission gear 44. A transmission key 42 connecting the winding pulley 38, the transmission gear 44, and the drum is slidably fitted at the center position of the hoisting module 45. The main body of the transmission gear 44 is rotatably fitted on a convex shaft provided at one end of the fixed end cover 43. The conical platform serves as its transmission structure and is engaged with the transmission key 42 for transmission. And the first gear 16 and the second gear 24 have the same structure. The center position of the drum in the hoisting module 45 and the transmission key 42 are in clearance spline fit, and the transmission key 42 can slide at the centers of the winding pulley 38, the transmission gear 44, and the drum; a limiting groove is provided on the limiting sleeve 46, a limiting rod 421 is fixed at the fitting end of the transmission key 42 and the limiting sleeve 46, and the limiting rod 421 is fitted in the limiting groove. The limiting groove is a C-shaped groove, and both ends are transverse grooves.

[0041] During specific operation, when lifting the ALC board 7, pull the transmission key 42 backward along the limit rod 421 and snap it into the transverse groove. At this time, the transmission key 42 is separated from the winding pulley 38. When the power mechanism 5 is started, large-stroke winding can be performed. Tie the rope that bypasses the lifting hoist 41 to the standby ALC board 7. Drive the winding module 45 to wind by using the power mechanism 5 to lift and transport the ALC board 7. After the lever lifting assembly 3 is adjusted to the working position, push the transmission key 42 back to the front end and snap it into the transverse groove. At this time, the transmission key 42 is keyed to the winding pulley 38, and small-stroke lifting is performed by using the power mechanism 5. During this process, the winding module 45 has been separated from the ALC board 7 and is not affected.

[0042] As an implementation manner of the present invention, a chain drive is provided between the transmission gear 44 and the power mechanism 5. All long-distance transmissions used in the present invention are chain drives to ensure a one-to-one transmission.

[0043] The working principle and usage process of the present invention: Lifting process: Before installation, the ALC boards 7 are mostly stacked horizontally in a concentrated manner. Remove the polygonal rod pin 25 and the fixed pin 23 in the present device, and rotate the rotation limit frame assembly 2 to rotate it outward. Thus, when taking the ALC board 7, the whole device is in an L shape, close to one side of the stacked ALC board 7 pile. At the same time, pull the transmission key 42 backward along the limit rod 421 and snap it into the transverse groove. At this time, the transmission key 42 is separated from the winding pulley 38. When the power mechanism 5 is started, large-stroke winding can be performed. With the fixed limit frame assembly 1 and the moving chassis 6 as supports, wind the rope in the winding module 45 around the lifting hoist 41 and tie it to the ALC board 7. Then start the power mechanism 5, and slowly lift the ALC board 7 with the assistance of personnel, and push the device to move it to the installation position. After reaching the designated position, stand the ALC board 7 upright on the ground;

[0044] Lifting process: When the ALC board 7 is transported to the designated position and stands upright, adjust the position of the entire device, and then rotate the limit frame assembly 2 to make it parallel to the fixed limit frame assembly 1. Install the fixing pin 23 and the polygonal rod pin 25 to fix the rotating limit frame assembly 2. Adjust the adjusting screws 15 at both ends so that the lifting feet 332 provided at the bottom of the lever lifting assemblies 3 at both ends are inserted into the bottom of the ALC board 7. At the same time, the lifting plate frames 31 at both ends are closely attached to the ALC board 7. Then start the power mechanism 5. The power mechanism 5 drives the transmission gear 44 and the first gear 16 to rotate simultaneously. Through the transmission of the polygonal rod pin 25 and the second gear 24, the winding pulleys 38 at both ends of the ALC board 7 rotate synchronously, so that the front ends of the lifting feet 332 in the inclined state pry the ALC board 7 to lift the ALC board 7. At the same time, the rolling wheel sets 333 provided at the lower ends of the lifting feet 332 touch the ground, so as to support the movement of the ALC board 7. When the operator installs the ALC board 7, the position of the ALC board 7 can be adjusted more easily. Continuous clamping can facilitate the operator to observe and position at a long or short distance, so as to perform rapid installation accurately and without error;

[0045] Removal device: When the ALC board 7 is installed in place, the power mechanism 5 rotates in reverse to lower the ALC board 7 by the lever lifting assemblies 3 on both sides. Then the operator fixes and installs the placed ALC board 7 manually. After the installation is completed, move the lifting plate frames 31 on both sides backward to separate from the ALC board 7. After complete separation, remove the polygonal rod pin 25 and the fixing pin 23 again, and return the transmission key 42 to its original position for the next installation. The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
