Description

Technical Field

[0001] This invention belongs to the field of lifting equipment technology, and more specifically, it relates to a lifting and construction device and method for precast panels of steel-concrete composite beams. Background Technology

[0002] Precast panels for steel-concrete composite beams are typically large and heavy, making manual handling difficult and posing safety hazards. Lifting equipment can efficiently and safely complete lifting and transportation, and can be used in conjunction with cranes to achieve long-distance lifting. Therefore, lifting equipment is an important tool to ensure the construction quality, safety, and progress of precast panels for steel-concrete composite beams.

[0003] Currently, the following problems still exist during the hoisting of precast panels for steel-concrete composite beams:

[0004] 1. Generally, the pre-embedded hooks on the precast panels of steel-concrete composite beams are connected to the wire ropes on the lifting equipment by shackles. This makes it impossible to quickly connect the lifting equipment to the pre-embedded hooks on the precast panels of steel-concrete composite beams, thus reducing the lifting efficiency of the precast panels of steel-concrete composite beams.

[0005] 2. It is inconvenient for staff to adjust the angle of the precast panels of the steel-concrete composite beams appropriately, resulting in a large deviation in the position of the precast panels after they are dropped, which increases the subsequent adjustment time of the precast panels of the steel-concrete composite beams. Summary of the Invention

[0006] This disclosure relates to a hoisting and construction device and method for precast panels of steel-concrete composite beams, comprising a hoisting mechanism, a quick-release mechanism, a support and anti-detachment mechanism, and a control mechanism. When two drive screws move two connecting plates inward, four L-shaped connecting hooks move inward simultaneously under the action of four steel wire ropes. When two drive screws move two connecting plates outward, four L-shaped connecting hooks move outward simultaneously under the action of four return springs, improving the hoisting efficiency of precast panels of steel-concrete composite beams. It allows two workers to adjust the angle of the precast panels of steel-concrete composite beams appropriately using two control handles, making the position of the precast panels after descent more accurate and reducing subsequent adjustment time.

[0016] In another aspect, this disclosure provides a method for hoisting and installing precast panels of steel-concrete composite beams, including the following steps:

[0017] 1) Adjust the position of the hook connecting frame appropriately so that the lifting construction frame is in a balanced state after the hook connecting frame is connected to the hook on the crane. Then tighten the four screws on the lifting construction frame to ensure that the adjusted hook connecting frame does not move.

[0018] 2) Use a crane to move the hoisting construction frame above the precast panel of the steel-concrete composite beam to be hoisted, and then slightly adjust the position of the hoisting construction frame so that the hoisting construction frame and the precast panel of the steel-concrete composite beam are on the same center plane;

[0019] 3) Two staff members simultaneously press down on the control handle and wait for the dual-head motor to complete its operation;

[0020] 4) The precast panels of the steel-concrete composite beam are moved to the designated position by a crane. Before they are lowered, the staff adjusts the angle of the precast panels of the steel-concrete composite beam appropriately using two control handles.

[0021] 5) The staff will press down on the two control handles again and wait for the dual-head motor to finish working.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This invention allows workers to easily adjust the position of the hook connecting frame, ensuring that the hoisting frame is basically balanced after the hook connecting frame contacts the hook; it also facilitates adjustment of the hook connecting frame using four limit screws; when adjusting the hook connecting frame, workers can first connect the hook connecting frame to the hook, and then move the hook connecting frame upwards using the hook, which helps workers observe the tilt of the hoisting frame and accurately adjust the position of the hook connecting frame based on the tilt.

[0024] Furthermore, when the two drive screws move the two connecting plates inward, the four L-shaped connecting hooks move inward simultaneously under the action of the four steel wire ropes, realizing the rapid separation of the four L-shaped connecting hooks from the four pre-embedded hooks on the precast panel of the steel-concrete composite beam; when the two drive screws move the two connecting plates outward, the four L-shaped connecting hooks move outward simultaneously under the action of the four return springs, realizing the rapid connection of the four L-shaped connecting hooks from the four pre-embedded hooks on the precast panel of the steel-concrete composite beam, thus improving the hoisting efficiency of the precast panel of the steel-concrete composite beam.

[0025] 2. The four supporting springs of this invention provide support for the hoisting construction frame, ensuring that after the four L-shaped connecting hooks are connected to the four pre-embedded hooks on the precast panel of the steel-concrete composite beam, the four L-shaped connecting hooks can always be in contact with the four pre-embedded hooks on the precast panel of the steel-concrete composite beam, thus preventing the four L-shaped connecting hooks from separating from the four pre-embedded hooks on the precast panel of the steel-concrete composite beam during hoisting.

[0026] 3. This invention allows two workers to adjust the angle of the precast steel-concrete composite beam panel appropriately using two control handles, making the position of the precast steel-concrete composite beam panel more accurate after it is lowered, which helps to reduce the subsequent adjustment time of the precast steel-concrete composite beam panel; the setting of two reset baffles and reset springs provides an elastic positioning effect for the two control handles, preventing the two control handles from swinging during the hoisting of the precast steel-concrete composite beam panel.

[0027] In addition, when the four L-shaped connecting hooks need to be connected or disconnected from the four pre-embedded hooks on the precast panel of the steel-concrete composite beam, the workers need to press down on the two control handles. When the two control handles are pressed down, the two control handles do not change angle or change only slightly under the action of the return spring, so that the hoisting construction frame will drive the four L-shaped connecting hooks to move down simultaneously. When the elastic force of the four support springs after compression is greater than the tension of the return spring, the hoisting construction frame stops moving outward, causing the two control handles to change angle.

[0028] In addition, when the two angle limit rods move to the other end of the four arc-shaped limit holes, the two angle limit rods can press the two control buttons in the two U-shaped connecting seats; when the two control buttons are in the pressed state, the controller controls the double-head motor to rotate forward for a period of time; when the two control buttons are pressed again, the controller controls the double-head motor to rotate in reverse for a period of time, so that when the hoisting construction frame drives the four L-shaped connecting hooks to move downward to the designated position, the double-head motor can work automatically.

[0053] Its specific functions are as follows: Because the hook connecting frame 202 is slidably installed on the hoisting construction frame 201, it is convenient for the staff to adjust the position of the hook connecting frame 202 appropriately, ensuring that the hoisting construction frame 201 is basically in a balanced state after the hook connecting frame 202 contacts the hook; and because the bottom of the hook connecting frame 202 contacts the top of the four screws, it is convenient to adjust the hook connecting frame 202 by limiting the position of the four screws; when adjusting the hook connecting frame 202, the staff can first connect the hook connecting frame 202 to the hook, and then move the hook connecting frame 202 upward through the hook, which is conducive to the staff to observe the tilt of the hoisting construction frame 201 and to accurately adjust the position of the hook connecting frame 202 according to the tilt.

[0054] Furthermore, because the four steel wire ropes 304 are slidably installed inside the hoisting construction frame 201, and the outer ends of the four steel wire ropes 304 are fixedly connected to the four L-shaped connecting hooks 203, and the inner ends of the four steel wire ropes 304 are fixedly connected to the two connecting plates 302, when the two drive screws 303 drive the two connecting plates 302 to move inward, the four L-shaped connecting hooks 203 can move inward simultaneously under the action of the four steel wire ropes 304, realizing the rapid separation of the four L-shaped connecting hooks 203 from the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam; and because the four circular reset... Rod 205 is slidably mounted on four limiting baffles 204, and four return springs 206 are sleeved on the outside of the four circular return rods 205, and the four return springs 206 are located inside the four limiting baffles 204. When the two drive screws 303 drive the two connecting plates 302 to move outward, the four L-shaped connecting hooks 203 move outward simultaneously under the action of the four return springs 206, realizing the rapid connection between the four L-shaped connecting hooks 203 and the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam, thereby improving the hoisting efficiency of the precast panel 100 of the steel-concrete composite beam.

[0055] In this embodiment of the disclosure, such as Figure 7 and Figure 9 As shown, the anti-detachment support mechanism 400 includes: circular guide shafts 401 and anti-detachment support discs 402; there are four circular guide shafts 401, and the four circular guide shafts 401 are slidably installed on the hoisting construction frame 201; there are four anti-detachment support discs 402, and the four anti-detachment support discs 402 are fixedly installed at the bottom of the four circular guide shafts 401, and the bottom of the four anti-detachment support discs 402 is in contact with the precast panel 100 of the steel-concrete composite beam; the anti-detachment support mechanism 400 also includes: limiting retaining rings 403 and support springs 404; there are four limiting retaining rings 403, and the four limiting retaining rings 403 are fixedly installed at the top of the four circular guide shafts 401; there are four support springs 404, and the four support springs 404 are sleeved on the outside of the four circular guide shafts 401, and the four support springs 404 are located between the hoisting construction frame 201 and the four anti-detachment support discs 402;

[0056] Its specific function is as follows: Since the four support anti-detachment discs 402 are fixedly installed at the bottom of the four circular guide shafts 401, and the bottom of the four support anti-detachment discs 402 is in contact with the precast panel 100 of the steel-concrete composite beam, and the four support springs 404 are located between the hoisting construction frame 201 and the four support anti-detachment discs 402, they play a supporting role for the hoisting construction frame 201. This ensures that after the four L-shaped connecting hooks 203 are connected to the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam, the four L-shaped connecting hooks 203 can always be in contact with the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam, thus preventing the four L-shaped connecting hooks 203 from separating from the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam during hoisting.

[0057] In this embodiment of the disclosure, such as Figures 8 to 10As shown, the control mechanism 500 includes: a U-shaped connecting seat 501, a rotating shaft 502, and a control handle 503; two U-shaped connecting seats 501 are provided, and the two U-shaped connecting seats 501 are fixedly installed on the front and rear sides of the hoisting construction frame 201, and two arc-shaped limiting holes 5011 are respectively opened on the two U-shaped connecting seats 501; two rotating shafts 502 are provided, and the two rotating shafts 502 are rotatably installed on the two U-shaped connecting seats 501; two control handles 503 are provided, and the two control handles 503 are fixedly installed on the outside of the two rotating shafts 502; the control mechanism 500 also includes: an angle limiting rod 504, a reset baffle 505, a reset tension spring 506, and a control button 507.

[0058] Its specific functions are as follows: Since the two U-shaped connecting seats 501 are fixedly installed on the front and rear sides of the hoisting construction frame 201, and the two rotating shafts 502 are rotatably installed on the two U-shaped connecting seats 501, and the two control handles 503 are fixedly installed on the outside of the two rotating shafts 502, it is convenient for two workers to adjust the angle of the precast steel-concrete composite beam panel 100 appropriately through the two control handles 503, so that the position of the precast steel-concrete composite beam panel 100 after falling is more accurate, which helps to reduce the subsequent adjustment time of the precast steel-concrete composite beam panel 100; and since the two reset baffles 505 are fixedly installed on the two U-shaped connecting seats 501, and the outer ends of the two reset baffles 505 are in contact with the two control handles 503, and the reset tension spring 506 is fixedly installed on the two control handles 503, it plays an elastic positioning role for the two control handles 503, preventing the two control handles 503 from swinging during the hoisting of the precast steel-concrete composite beam panel 100;

[0059] Furthermore, when the four L-shaped connecting hooks 203 need to be connected or disconnected from the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam, the operator needs to press down on the two control handles 503. When the two control handles 503 are pressed down, under the action of the return spring 506, the two control handles 503 do not change their angle or only change their angle slightly, causing the hoisting construction frame 201 to drive the four L-shaped connecting hooks 203 to move downward simultaneously; when the elastic force of the four support springs 404 after compression is greater than the tension of the return spring 506... When the force is applied, the hoisting construction frame 201 stops moving outward, causing the two control handles 503 to change angle; since the two control buttons 507 are fixedly installed inside the two U-shaped connecting seats 501, and the two control buttons 507 are electrically connected to the controller 700, and the dual-head motor 301 is also electrically connected to the controller 700, when the two angle limit rods 504 move to the other end of the four arc-shaped limit holes 5011, the two angle limit rods 504 can press the two control buttons 507 in the two U-shaped connecting seats 501;

[0060] In addition, when the two control buttons 507 are pressed, the controller 700 controls the dual-head motor 301 to rotate forward for a period of time; when the two control buttons 507 are pressed again, the controller 700 controls the dual-head motor 301 to rotate in reverse for a period of time, so that when the hoisting construction frame 201 drives the four L-shaped connecting hooks 203 to move downward to the designated position, the dual-head motor 301 can work automatically.

[0061] This invention provides a method for hoisting and installing precast panels of steel-concrete composite beams, comprising the following steps:

[0062] 1) Adjust the position of the hook connecting frame 202 appropriately so that the lifting construction frame 201 is in a balanced state after the hook connecting frame 202 is connected to the hook on the crane. Then tighten the four screws on the lifting construction frame 201 to ensure that the adjusted hook connecting frame 202 does not move.

[0063] 2) Use a crane to move the hoisting construction frame 201 above the precast steel-concrete composite beam panel 100 to be hoisted, and then slightly adjust the position of the hoisting construction frame 201 so that the hoisting construction frame 201 and the precast steel-concrete composite beam panel 100 are on the same central plane.

[0064] 3) Two staff members simultaneously press down on control handle 503 and wait for the dual-head motor 301 to complete its operation;

[0065] 4) The precast steel-concrete composite beam panel 100 is moved to the designated position by a crane. Before it is lowered, the staff adjusts the angle of the precast steel-concrete composite beam panel 100 appropriately using two control handles 503.

[0066] 5) The staff will press down on the two control handles 503 again and wait for the dual-head motor 301 to finish working.

[0067] The specific usage and function of this embodiment are as follows:

[0068] When using this invention, firstly, adjust the position of the hook connecting frame 202 appropriately so that after the hook connecting frame 202 is connected to the hook on the crane, the hoisting construction frame 201 is in a balanced state. When adjusting the hook connecting frame 202, the operator can first connect the hook connecting frame 202 to the hook, and then move the hook connecting frame 202 upwards through the hook. This allows the operator to observe the tilt of the hoisting construction frame 201 and accurately adjust the position of the hook connecting frame 202 according to the tilt. Afterwards, tighten the four screws on the hoisting construction frame 201 to ensure that the adjusted hook connecting frame 202 is in a stable position. 02. No movement occurs; the hoisting construction frame 201 is moved by a crane to above the precast steel-concrete composite beam panel 100 to be hoisted, and then the position of the hoisting construction frame 201 is slightly adjusted so that the hoisting construction frame 201 and the precast steel-concrete composite beam panel 100 are on the same center plane; two workers simultaneously press down the control handle 503. When the two control buttons 507 are in the pressed state, the controller 700 controls the double-head motor 301 to rotate forward for a period of time. When the two drive screws 303 drive the two connecting plates 302 to move outward, the four L-shaped connecting hooks 203 are in the four Under the action of the return spring 206, they move outward simultaneously, realizing the rapid connection between the four L-shaped connecting hooks 203 and the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam, waiting for the double-head motor 301 to complete its work; the precast panel 100 of the steel-concrete composite beam is moved to the designated position by the crane. Before falling, the operator adjusts the angle of the precast panel 100 of the steel-concrete composite beam appropriately through the two control handles 503, so that the position of the precast panel 100 of the steel-concrete composite beam is more accurate after falling, which helps to reduce the subsequent adjustment time of the precast panel 100 of the steel-concrete composite beam; when hoisted to the designated position... The staff pressed down the two control handles 503 again. When the two control buttons 507 were pressed again, the controller 700 controlled the dual-head motor 301 to reverse for a period of time. When the two drive screws 303 drove the two connecting plates 302 to move inward, the four L-shaped connecting hooks 203 could move inward simultaneously under the action of the four steel wire ropes 304. This achieved the rapid separation of the four L-shaped connecting hooks 203 from the four pre-embedded hooks on the precast panel 100 of the steel-concrete composite beam, improving the hoisting efficiency of the precast panel 100 of the steel-concrete composite beam. The staff then waited for the dual-head motor 301 to finish its work.
