Description

Technical Field

[0001] This invention belongs to the field of prefabricated buildings, and in particular relates to a modular splicing device for energy-saving walls in green buildings. Background Technology

[0002] With the widespread adoption of green building concepts and the rapid development of the prefabricated building industry, modular energy-saving wall panels, with their advantages of thermal insulation, low carbon emissions, environmental friendliness, convenient construction, and high degree of industrialization, have become a core component of modern green building envelopes and are widely used in various construction projects, including residential, public, and industrial buildings. Compared to traditional cast-in-place walls, prefabricated modular energy-saving wall panels can be prefabricated in factories and assembled on-site, significantly reducing wet work on construction sites, lowering material waste and construction pollution. This aligns with the industry trend of energy conservation, emission reduction, and green construction, and is a key technological carrier for promoting the industrialization and greening of the building industry.

[0003] Currently, the on-site splicing construction process for energy-saving prefabricated walls in green buildings still has many technical shortcomings. The core defect lies in the fact that the splicing operation relies on the cooperation of multiple people, and a single person cannot complete the construction independently. This results in low overall assembly efficiency, which seriously restricts the construction progress and promotion and application of prefabricated walls. The existing prefabricated wall splicing construction process mainly includes the following steps: First, workers measure and mark the points to be assembled to determine the position and size of the wall panels. Then, shims are laid to ensure that the top and bottom edges of the wall are aligned. Next, the prefabricated wall panels are hoisted into place. In this process, multiple people are required to be responsible for the hoisting and alignment of the wall and the installation of diagonal braces. This process requires at least 3-5 construction workers to cooperate, resulting in a large labor input and high labor costs. At the same time, the existing splicing operation is highly dependent on the experience of manual operators. If there are inexperienced personnel, problems such as poor operation coordination, positioning accuracy deviation, and calibration delays are likely to occur, further reducing construction efficiency. Summary of the Invention

[0004] This invention addresses the technical problems existing in existing prefabricated wall assembly by proposing a green building energy-saving modular splicing device that is rationally designed, simple in structure, easy to operate, and can effectively enable rapid assembly with a small number of workers.

[0005] To achieve the above objectives, the technical solution adopted by this invention is as follows: This invention provides a modular splicing device for energy-saving green building walls, including a mobile trolley and an assembly base disposed at the front end of the mobile trolley. An assembly frame is disposed on the assembly base, and the assembly frame is slidably disposed on both sides of the assembly base. A plate straightening mechanism and a diagonal brace placement mechanism are disposed on the side of the assembly frame away from the assembly base. The plate straightening mechanism includes a rotary motor reducer that can be lifted and lowered on the assembly frame and a mounting base disposed on the power end of the rotary motor reducer. A push-pull cylinder is disposed on the mounting base, and a pull rod is fitted onto the piston end of the push-pull cylinder. The pull rod faces the assembly base. A limit cylinder is also disposed on the assembly frame, and a baffle is disposed on the limit cylinder. The diagonal brace placement mechanism includes a fixed plate installed at the bottom of the mounting base and... A through hole is provided in the fixed plate. An open rotary gear ring is provided on one side of the fixed plate and is coaxially arranged with the through hole. The fixed plate is also provided with guide rollers for supporting the open rotary gear ring. The guide rollers are spaced apart along the inner wall of the open rotary gear ring. The fixed plate is also provided with a first drive gear and a second drive gear for driving the open rotary gear ring to rotate. The first drive gear and the second drive gear are spaced apart. The fixed plate is provided with a drive motor for driving the first drive gear and the second drive gear to rotate respectively. An electric gripper is fixed on the open rotary gear ring. The electric gripper makes the axis of the support rod coincide with the axis of the open rotary gear ring. The fixed plate is also provided with a notch for the support rod to enter into the through hole. The notch is connected to the through hole.

[0006] Preferably, the plate straightening mechanism is arranged at intervals on the side of the assembly frame.

[0007] Preferably, a central column is provided in the middle of the assembly base, and a two-way hydraulic cylinder is installed on the central column. The piston end of the two-way hydraulic cylinder is connected to the assembly frame.

[0008] Preferably, the assembly base has a U-shaped cross-section, and the assembly frame is disposed in the groove of the assembly base.

[0009] Preferably, the bottom of the assembly base is provided with embedded casters, which are spaced apart at the front and rear ends of the assembly base.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are as follows: The present invention provides a modular splicing device for energy-saving walls in green buildings. Through the plate straightening mechanism set on the assembly frame, the plate can be inserted into the steel bar without any restraint. At the same time, the setting of the diagonal brace placement mechanism realizes the automatic placement and tightening of the diagonal brace, so that the entire assembly process can be completed by only 2 people.

[0013] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Example 1, as Figures 1-6 As shown, this embodiment aims to provide a modular splicing device for green building energy-saving walls that assists workers in assembling wall panels, thereby reducing the number of workers required and improving work efficiency. To achieve this objective, this embodiment provides a mobile trolley 1 and an assembly base 2 positioned at the front end of the mobile trolley 1. In this embodiment, the mobile trolley 1 has two main functions: one is to move the assembly base 2 and maintain its balance; the other is to install a hydraulic station to provide power to the hydraulic cylinders. In this embodiment, to prevent the entire weight of the assembly base 2 from pressing on the mobile trolley 1, embedded casters 24 are provided at the bottom of the assembly base 2, spaced at both the front and rear ends. This avoids the mobile trolley 1 bearing the entire weight, and also lowers the center of gravity, ensuring structural stability.

[0016] Considering that the straightening of the wall panel needs to be done from both sides of the wall panel, while the installation of the diagonal brace needs to be done from the front of the wall panel, in this embodiment, an assembly frame 3 is provided on the assembly base 2. The assembly frame 3 is slidably arranged on both sides of the assembly base 2. The assembly frame 3 is arranged in the shape of a cuboid frame. In this embodiment, for aesthetic purposes, it is covered with a skin.

[0017] Since existing prefabricated wall panels are between 2.8m and 3m high and about 2m wide, in this embodiment, the height of the assembly frame 3 is about 2m and the width of the assembly base 2 is about 1.8m. This allows the assembly frame 3 to extend to meet the lateral limiting requirements of the prefabricated wall panel, while its repositioning allows for the installation of the diagonal braces. In this embodiment, for stable sliding, a central column 21 is provided in the middle of the assembly base 2, and two bidirectional hydraulic cylinders 22 are installed on the central column 21. The two bidirectional hydraulic cylinders 22 are spaced vertically, and their piston ends are connected to the assembly frame 3. A guide rail 23 is also provided on the assembly base 2, and a slider 33 that cooperates with the guide rail 23 is provided at the bottom of the assembly frame 3. Furthermore, considering the height of the assembly frame 3, the cross-section of the assembly base 2 is U-shaped, and the assembly frame 3 is positioned within the groove of the assembly base 2.

[0018] To achieve the straightening of the prefabricated wall panels and the installation of diagonal braces, in this embodiment, a panel straightening mechanism 4 and a diagonal brace placement mechanism 5 are provided on the side of the assembly frame 3 away from the assembly base 2. The panel straightening mechanism 4 includes a rotary motor reducer 45 that is vertically mounted on the assembly frame 3 and a mounting base 46 located at the power end of the rotary motor reducer 45. In this embodiment, a lifting motor reducer 41 is installed on the top of the assembly frame 3, and a lifting screw 43 is connected to the output end of the lifting motor reducer 41. The lead screw 43 is fitted with a lead screw nut seat 44, which is mounted on the motor base 42. Meanwhile, the rotary motor reducer 45 is mounted on the motor base 42. Guide sliders are provided on both sides of the motor base 42, and guide rails that cooperate with the guide sliders are provided on the assembly frame 3. In this way, the lifting function of the rotary motor reducer 45 is realized under the action of the lifting motor reducer 41. The main purpose of the lifting function is to cooperate with the inclined brace placement mechanism 5, and it has no effect on the straightening of the plate.

[0019] The uprighting of the plate is mainly achieved by the push-pull cylinder 47. In this embodiment, the mounting base 46 is L-shaped, and the push-pull cylinder 47 is installed on the mounting base 46. The piston end of the push-pull cylinder 47 is fitted with a pull rod 48, which faces the assembly base 2. The pull rod 48 can be a straight rod or an L-shaped rod. At the same time, a limit cylinder 31 is also installed on the assembly frame 3, and a baffle 32 is installed on the limit cylinder 31. In this way, the moving trolley 1 is first placed in the correct position, and the bidirectional hydraulic cylinder 22 and the push-pull cylinder 47 are opened to the maximum. When the crane carries the prefabricated wall panel to the designated position, the push-pull cylinder 47 pulls the tie rod 48 to move towards the assembly frame 3, while the limit cylinder 31 pushes the baffle 32 towards the wall panel. When the distance between the push plate and the tie rod 48 is slightly larger than the wall panel, the bidirectional hydraulic cylinder 22 moves. When it is ensured that the width on both sides is also slightly larger than the wall panel, the position is accurate, and the prefabricated wall panel can be lowered normally. If there is any bending of the reinforcing steel, the workers need to straighten the reinforcing steel in advance. In this way, the placement can be successful.

[0020] After successful placement, the diagonal bracing needs to be installed. Therefore, the diagonal bracing placement mechanism 5 includes a fixed plate 51 installed at the bottom of the mounting base 46 and a through hole 511 in the fixed plate 51. The fixed plate 51 is a vertical plate, positioned perpendicular to the mounting base 46. The through hole 511 is located at the center of the fixed plate 51. An open rotary gear ring 52 is provided on one side of the fixed plate 51. The open rotary gear ring 52 is not a closed gear ring; it has an opening. The diameter of the through hole 511 is slightly smaller than the inner diameter of the open rotary gear ring 52. Of course, the open rotary gear ring 52 and the through hole 511 are coaxially arranged. At the same time, the fixed plate 51 is also provided with guide rollers 53 for supporting the open rotary gear ring 52. The guide rollers 53 are spaced along the inner wall of the open rotary gear ring 52. In this embodiment, four guide rollers 53 are provided. The guide rollers 53 have two functions: one is to support the open rotary gear ring 52, and the other is to limit the open rotary gear ring 52 to prevent it from falling off the guide rollers 53. For this purpose, the guide rollers 53 are provided with annular grooves.

[0021] Meanwhile, a first drive gear 54 and a second drive gear 55 are also provided on the fixed plate 51 for driving the open rotary gear ring 52 to rotate. The first drive gear 54 and the second drive gear 55 are spaced apart, and the distance between the first drive gear 54 and the second drive gear 55 is greater than the length of the opening, to ensure that at any time one drive gear is engaged with the open rotary gear ring 52. Since a certain torque is required, a drive motor 56 is provided on the fixed plate 51 for driving the first drive gear 54 and the second drive gear 55 to rotate respectively.

[0022] Meanwhile, an electric gripper 57 is fixed on the open rotary gear ring 52. In order to avoid the guide roller 53, in this embodiment, a connecting seat 521 is fixed on the side plate of the open rotary gear ring 52. The connecting seat 521 is inverted L-shaped. In this way, the electric gripper 57 can avoid the guide roller 53. At the same time, the position of the electric gripper 57 should be such that the axis of the support rod coincides with the axis of the open rotary gear ring 52. In this way, when the open rotary gear ring 52 rotates, the support rod can rotate. Since the support rod can be regarded as two parts, one part is the main part and the other part is the bolts at both ends of the main part. The main part and the bolts are threadedly connected, and the end of the bolt away from the main part is provided with a connecting ring. In this embodiment, a connecting ring with an opening is used. At the same time, in order to facilitate the insertion of the support rod, a notch for the support rod to enter the through hole 511 is also provided on the fixing plate 51. The notch is connected to the through hole 511.

[0023] In this way, during implementation, the worker places the support rod onto the electric gripper 57. Since the wall panel is still in the hoisting state at this time (for safety reasons), after the worker places the support rod, one worker holds the wall panel. Of course, it is also possible to do so without holding it and rely solely on hoisting. Then, the rotary motor reducer 45 is activated, causing the support rod to tilt. Then, the double-acting hydraulic cylinder 22 is completely reset, and the lifting motor reducer 41 is activated to control the support rod to descend, so that the connecting ring of the support rod is inserted into the connecting ring of the panel. Then, the drive motor 56 is activated to control the main pipe of the support rod to rotate. Since the bolts at both ends are limited, the bolts at both ends extend to complete the clamping of the wall panel. At this time, the electric gripper 57 can release the support rod, control the moving trolley 1 to disengage, and then the wall panel can be grouted.

[0024] Since two diagonal braces need to be installed, and the vertical positioning of the plate is more stable, the plate straightening mechanism 4 is set at intervals on the side of the assembly frame 3.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
