Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to a laser hoisting positioning frame and an assembled wall installation method. Background Art

[0002] Prefabricated buildings are buildings assembled on site from prefabricated parts. According to the form of prefabricated parts and the construction method, they are divided into five types: block buildings, plate buildings, box buildings, skeleton plate buildings, and lifting plate and layer buildings. During the construction of prefabricated buildings, it involves using a lifting device to lift the wall above the pre-buried steel bars, and then constantly adjusting the angle of the wall so that the reserved holes on the wall are aligned with the steel bars one by one, and then lowering the wall so that the steel bars are inserted into the reserved holes of the wall.

[0003] When the wall of the prefabricated building is matched, because the embedded steel bars and the wall are higher, when the wall is hoisted above the embedded steel bars and the reserved holes on the wall are aligned with the steel bars, it is difficult for the staff below or the hoisting operator to observe the alignment of the steel bars and the reserved holes. Therefore, the alignment operation is very troublesome, which greatly reduces the efficiency of positioning and alignment. In the process of hoisting the wall to pass through the steel bars, because the steel bars are thin and tall, and the lower end is the fixed end and the upper end is the free end, the upper end of the steel bars is prone to deflection and bending, that is, the central axis of the steel bars cannot remain vertical, which will affect The steel bars and the reserved holes need to be aligned and positioned or the wall needs to be sunk, and then the assembled wall needs to be adjusted in the up and down directions so that the two side surfaces of the assembled wall are flush. Therefore, when the above-mentioned prefabricated walls are actually assembled, the actual operation efficiency is low and the assembly accuracy is poor. Moreover, since the steel bars and the reserved holes contain multiple groups, the steel bars and the reserved holes need to be aligned and plugged at the same time, which requires close cooperation between the operating personnel and the hoisting personnel, resulting in low assembly efficiency. In addition, the assembled wall at the upper position is prone to deflection, which in turn causes the steel bars at the lower position to break. Summary of the invention

[0043] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described in conjunction with the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors;

[0044] The following is combined with Figures 1 to 13 , the laser hoisting positioning frame of the present invention is described in detail:

[0045] When the assembled wall is actually hoisted and installed, when it is hoisted and installed on a building with lower floors, the assembled wall can be hoisted by a vehicle-mounted hoisting arm. When it is hoisted and installed on a high-rise building with higher floors, it is necessary to build a fixed hoisting equipment to realize the installation between the assembled walls. During the actual installation, in order to ensure that the assembled wall at the upper position can accurately fall on the upper position of the assembled wall at the lower position, and to ensure that the steel bars of the assembled wall at the lower position can be accurately inserted into the reserved holes of the assembled wall at the upper position, it is generally necessary for the operating personnel to assist the hoisting personnel to make fine adjustments to the position, so that the steel bars of the assembled wall at the lower position can be aligned with the reserved holes of the assembled wall at the upper position. The above-mentioned fine-tuning process is relatively slow, and the accuracy of the hoisting equipment is poor. Repeated correction is required to ensure that the above-mentioned steel bars are aligned with the reserved holes, which leads to very low construction efficiency.

[0046] To this end, the present invention proposes a laser hoisting positioning frame, comprising:

[0047] The plug-in frame 100 is arranged below the lifting equipment;

[0048] A plurality of plug-in pipes 110 are arranged at intervals along the length direction of the plug-in frame 100, and the plug-in pipes 110 are used to connect the steel bars at the upper end of the wall; an adjustment frame 200 is arranged above the plug-in frame 100, and is used to adjust the horizontality of the plug-in frame 100;

[0049] A driving unit, used for driving the insertion and fixing or separation of the plug-in tube 110 and the steel bars at the upper end of the wall;

[0050] The laser detection head 300 is installed on the plug-in frame 100 and is used to measure the coordinate information of the wall. The laser detection head 300 transmits the detected coordinate signal to the central control unit, and the central control unit is used to control the adjustment frame 200 to adjust the horizontality of the plug-in frame 100.

[0051] In one embodiment, multiple groups of laser detection heads 300 can be installed on the plug-in frame 100. Through the multiple groups of laser detection heads 300, the position signal of the upper end of the wall can be obtained more accurately, and the coordinate signal of the steel bars at the upper end of the wall can be obtained. By adjusting the position of the plug-in tube 110, it can be ensured that the position of the plug-in tube 110 corresponds to the position of the steel bars at the upper end of the wall, so as to ensure that the steel bars at the upper end of the wall are accurately inserted into the plug-in tube 110, thereby ensuring that the plug-in frame 100 can effectively implement the grasping of the wall and ensure that the wall is accurately hoisted to the top of the installed wall.

[0052] In one embodiment, when the plug-in tube 110 is fixed to the steel bars on the wall, the wall will be tilted to a certain extent and the horizontality of the upper end of the wall cannot be guaranteed. Therefore, the horizontality of the plug-in frame 100 can be effectively adjusted through the central control unit to ensure that the upper and lower walls are aligned, thereby ensuring the accuracy of the installation position.

[0053] In one embodiment, in order to ensure that the adjustment frame 200 is reliably positioned with the upper end of the wall, thereby ensuring that the steel bars at the upper end of the wall are accurately inserted into the insertion tube 110, a positioning frame 400 is provided below the adjustment frame 200, and the positioning frame 400 and the adjustment frame 200 form a vertical sliding fit, and the positioning frame 400 abuts against or separates from the upper end of the wall.

[0054] In one embodiment, the positioning frame 400 is in the shape of a rectangular frame as a whole. The positioning frame 400 is against the two sides of the upper end of the wall, and the plug-in tube 110 extends out of the frame surface of the positioning frame 400, so that the steel bars at the upper end of the wall extend into the plug-in tube 110 to ensure that the steel bars can be effectively fixed to the plug-in tube 110.

[0055] In one embodiment, in order to ensure that the plug-in tube 110 is integrated with the steel bars at the upper end of the wall, two groups of clamping arc blocks 120 are symmetrically arranged in the plug-in tube 110, and the gap between the two groups of clamping arc blocks 120 constitutes a channel for clamping the steel bars at the upper end of the wall. The upper ends of the two groups of clamping arc blocks 120 are movably installed on the plug-in frame 100, and the outer walls of the two groups of clamping arc blocks 120 are provided with driven inclined surfaces 121. The plug-in tube 110 is connected to a driving unit, and a driving inclined surface 111 is provided on the inner wall of the plug-in tube 110. The driving unit drives the plug-in tube 110 to move vertically and makes the driving inclined surface 111 abut against the driven inclined surface 121, so as to link the two groups of clamping arc blocks 120 to move closer.

[0056] In one embodiment, when the steel bars are clamped, the driving unit is started to move the plug-in tube 110 vertically, and the driving inclined surface 111 abuts against the driven inclined surface 121, thereby driving the two sets of clamping arc blocks 120 to approach, thereby clamping the steel bars to engage the wall.

[0057] In one embodiment, the plug-in tubes 110 are arranged in multiple groups at intervals along the length direction of the adjustment frame 200. In some embodiments, the plug-in tubes 110 are arranged in 6 groups or 8 groups at intervals along the length direction of the adjustment frame 200. When the adjustment frame 200 is combined with the wall, the clamping arc blocks 120 in the multiple groups of plug-in tubes 110 arranged at intervals can effectively clamp the steel bars, and then clamp and fix the entire wall, so that the wall can be hoisted onto the assembly base. This is an automated installation of multiple groups of walls in Xi'an, ensuring the installation accuracy between the walls.

[0058] In one embodiment, in order to ensure that the steel bars can be accurately inserted into the plug-in tube 110, the plug-in tube 110 is vertically slidably set on the support sleeve 130, and the support sleeve 130 is installed on the support slider 140. The support slider 140 is provided with a movable opening, and the support sleeve 130 extends into the movable opening and the pipe openings at both ends are provided with flanges 131, and the flanges 131 are abutted against the two side plates of the support slider 140. A support spring 132 is sleeved on the plug-in tube 110, and the two ends of the support spring 132 are respectively abutted against the support sleeve 130 and the outer wall of the plug-in tube 110.

[0059] In one embodiment, the movable opening on the support slider 140 is circular, and the diameter of the movable opening is larger than the diameter of the support sleeve 130, and the diameter of the movable opening is smaller than the diameter of the flange 131, so the support sleeve 130 can be moved in the movable opening of the support slider 140, so the plug-in tube 110 is in a floating state on the support slider 140, and when the upper end of the steel bar is inserted into the plug-in tube 110, the support sleeve 130 can slide on the support slider 140, thereby achieving a certain range of fine adjustment to adapt to the upper end of the wall steel bar. The error in the reinforcement arrangement position can ensure that the reinforcement can be reliably inserted into the plug-in tube 110, and then the driving unit is started to link the support slider 140 to move vertically, and when the support sleeve 130 moves vertically, the upper end of the linkage reinforcement is inserted into the plug-in tube 110, which can compress the support spring 132 in real time until the support sleeve 130 is used to implement elastic clamping of the two sets of clamping arc blocks 120 to ensure elastic clamping of the reinforcement to avoid clamping the reinforcement, and also ensure that the entire wall is bitten and lifted to implement the transportation of the wall.

[0060] In one embodiment, a support roller 141 is provided on the support slider 140, and the core of the support roller 141 is horizontally and rollingly arranged on the support rail 142. The support rail 142 is horizontally arranged, and an adjustment spring 143 is provided between adjacent support sliders 140. The adjustment spring 143 is arranged parallel to the support rail 142, and the support sliders 140 are all connected to one end of the adjustment push rod 144, and the adjustment push rod 144 is parallel to the support rail 142 and one end is connected to the adjustment frame 145, and an adjustment nut 1451 is provided on the adjustment frame 145, and an adjustment screw rod 1452 is provided in the adjustment nut 1451, and the adjustment screw rod 1452 is parallel to the support rail 142 and one end is rotatably installed on the support rail 142, and one end of the adjustment screw rod 1452 is connected to the adjustment motor 1453.

[0061] In one embodiment, in order to ensure the support of the entire wall and thus ensure that the wall is reliably lifted, the support roller 141 on the support slider 140 is rotatably set on the support track 142. The support track 142 can effectively support the support pipe sleeve 130 and the plug-in pipe 110 at the upper position, and the support sliders 140 are connected by adjusting springs 143, so that the spacing between the support sliders 140 can be adjusted by adjusting the motor 1453 to meet the requirements of clamping steel bars at different spacings at the upper end of the wall. The adjusting motor 1453 can be used to rotate the adjusting screw rod 1452, thereby linking the adjusting top rod 144 to slide along the length direction of the support track 142, so that adjacent support sliders 140 are moved closer or farther away, so as to implement synchronous compression or extension of the adjusting spring 143, so as to adjust the spacing between the plug-in pipes 110, so that the position of the plug-in pipe 110 corresponds to the position of the steel bars at the upper end of the wall, ensuring that the steel bars at the upper end of the wall can be accurately inserted into the plug-in pipe 110.

[0062] In one embodiment, in order to ensure that the upper end of the steel bar is inserted into the plug-in tube 110 and to ensure that the steel bar can be accurately introduced between the two groups of clamping arc blocks 120, a bell mouth 112 is provided at the lower end of the plug-in tube 110, and the two groups of clamping arc blocks 120 extend out of the upper end pipe mouth of the plug-in tube 110. The protruding ends of the two groups of clamping arc blocks 120 are provided with movable balls, and the movable balls rest on the cross brace 1421. The cross brace 1421 is installed above the support rail 142 and is parallel to each other. Specifically, it can be installed on the bottom surface of the plug-in frame 100.

[0063] In one embodiment, the protruding ends of the two groups of clamping arc blocks 120 are provided with movable balls, and the movable balls abut against the cross brace 1421. Therefore, when the steel bars are clamped, the two groups of clamping arc blocks 120 can be adjusted along with the adjustment of the position of the steel bars to ensure that the steel bars can be introduced into the position between the two groups of clamping arc blocks 120. By starting the driving unit, the plug-in tube 110 moves vertically, and the driving inclined surface 111 abuts against the driven inclined surface 121, thereby linking the two groups of clamping arc blocks 120 to approach, thereby clamping the steel bars to implement the bite of the wall.

[0064] In one embodiment, in order to implement the vertical drive of the plug-in tube 110, the driving unit includes a vertical rail 150, and the two ends of the support rail 142 are slidably set on the vertical rail 150. The upper end of the vertical rail 150 is installed on the plug-in frame 100. A driving nut is provided on the support rail 142, and the driving nut cooperates with the driving screw 1422. The driving screw 1422 is vertical and the upper end is connected to the driving motor 1423. The driving motor 1423 is installed on the plug-in frame 100.

[0065] In one embodiment, by starting the driving motor 1423, the support rail 142 moves vertically along the vertical rail 150, thereby driving the plug-in tube 110 to move downward to tighten the two sets of clamping arc blocks 120, and then clamp the steel bars to ensure clamping and fixing of the wall.

[0066] In one embodiment, in order to adjust the horizontality of the adjustment frame 200, the adjustment frame 200 includes a first adjustment frame 210 and a second adjustment frame 230. The plug-in frame body 100 is in the shape of a frame as a whole and is hinged to the first adjustment frame 210 at the middle section. The hinge axis of the plug-in frame body 100 is arranged horizontally. The first adjustment frame 210 is in the shape of a rectangular frame as a whole and a first adjustment inclined surface 211 is arranged on the lower frame surface. The first adjustment inclined surface 211 is symmetrically arranged on both sides of the first adjustment frame 210. A first adjustment roller 220 is arranged between the adjustment frame 200 and the first adjustment inclined surface 211. The first adjustment roller 220 abuts against the plug-in frame body 100 and the first adjustment inclined surface 211. The first adjustment rollers 220 arranged on both sides of the first adjustment frame 210 are connected to a first horizontal driving mechanism. The first horizontal driving mechanism drives the first adjustment roller 220 to move horizontally.

[0067] The middle section of the first adjustment frame 210 is hinged to the second adjustment frame 230, and the hinge axis of the first adjustment frame 210 is arranged perpendicular to the hinge axis of the second adjustment frame 230.
