Description

Technical Field

[0001] This invention relates to the field of unbalanced suspended platform installation technology, specifically to a fixing device and method for unbalanced suspended platforms used in high-altitude operations. Background Technology

[0002] In the modern civil engineering construction field, not only is applicability emphasized, but also time-saving, labor-saving and green construction is given more attention. The suspended platform for high-altitude operations mainly includes a support frame, a boom, a hoisting rope and a suspended platform. The support frame includes a front support frame and a rear support frame. During the erection process, the support frame is fixed to the building, and the boom is installed on the support frame.

[0003] Currently, in the process of erecting suspended platforms for high-altitude operations, the traditional approach is to choose a standard suspended platform and erect it on the roof. A large number of counterweights need to be installed on the rear support of the suspended platform to maintain its stable operation. Furthermore, since it is erected on the roof, it cannot provide an operating platform for the construction of the exterior facade of the structural beams and flower racks. Therefore, it is often necessary to erect additional external scaffolding to provide a working surface.

[0004] Later, a counterweight-free suspended platform emerged, which typically has only one support frame. One end of the boom is equipped with a fixing rope, and the other end with a hoisting rope. The support frame is located between the boom and the hoisting rope. The support frame is fixed to the roof by screwing screws on site, and the rope is then fixed to the ground by screwing screws. This eliminates the need for a large number of counterweights. However, the screws driven in can severely damage the roof, causing internal cracks and affecting subsequent construction. Summary of the Invention

[0005] The purpose of this invention is to provide a weightless suspended platform fixing device and method for high-altitude operations, so as to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a weightless suspended platform fixing device for high-altitude operations, comprising: The structural beam body is located on the building. Two structural beam bodies side by side form a group, and a group includes a front structural beam body and a rear structural beam body. A suspension mechanism, located on the structural beam of a building, is used to suspend ropes and a suspended basket. The suspension mechanism includes a support frame, which includes a front support frame and a rear support frame. A clamp-type fixing mechanism is used to secure the suspension mechanism and the structural beam body together at corresponding points; the front support is fixed to the front structural beam body by the fixing mechanism, and the rear support is fixed to the rear structural beam body by the fixing mechanism.

[0007] Furthermore, a positioning steel bar column is fixed on the structural beam body, and the bracket is provided with a through hole. The bracket passes through the through hole from the upper end of the positioning steel bar column and is then placed statically on the structural beam body. The position of the bracket can be pre-positioned.

[0008] Furthermore, the clamp-type fixing mechanism includes a double-ended screw, a nut, and an upper clamping plate and a lower clamping plate placed side by side. The upper clamping plate is located on the bracket, and the lower clamping plate is located on the structural beam body. The double-ended screw includes a first double-ended screw and a second double-ended screw. The double-ended screw passes through the upper clamping plate and the lower clamping plate sequentially from the outside of the structural beam body, and is then fixed to the end of the double-ended screw with a nut. This allows the upper clamping plate, the first double-ended screw, the lower clamping plate, and the second double-ended screw to form a receiving space, which secures the bracket and the structural beam body together.

[0009] Furthermore, the clamp-type fixing mechanism includes an upper pressing member and a U-shaped member. The U-shaped member includes a lower pressing member and two connecting members. The connecting members are symmetrically arranged on the lower pressing member. The lower pressing member adjusts the spacing between the two connecting members according to the width of the structural beam body, so that the connecting members fit the structural beam body. The upper pressing member is used to fix the two connecting members, so that the upper pressing member, one connecting member, lower pressing member and the other connecting member are assembled to form an accommodating space. This accommodating space surrounds and clamps the bracket and the structural beam body together.

[0010] Furthermore, the pressing component includes a pressing plate and a linear power component. The pressing plate is symmetrically provided with adjustment through holes, and a slidingly connected base plate is embedded at the bottom of the adjustment through holes. The linear power component includes a motor, which is located on the pressing plate. The output shaft of the motor is connected to a bidirectional lead screw, and sliders are symmetrically provided on the bidirectional lead screw. A nut adapted to the bidirectional lead screw is provided inside the slider, and the slider is fixedly connected to the base plate; this is used to control the synchronous movement of the slider and the base plate.

[0011] Furthermore, the connector includes a connecting rod and a lifting block. The bottom end of the connecting rod extends into the adjustment through hole and is fixed on the base plate. The lifting block is rotatably mounted on the top of the connecting rod and is used to control the connector to pass through the upper pressure member and the supporting U-shaped member.

[0012] Furthermore, the upper pressing component includes an upper pressing plate, on which two adjusting through holes are symmetrically arranged. A pair of gear rollers are arranged side by side in the horizontal direction within the adjusting through holes. The axis of the gear rollers is parallel to the length direction of the upper pressing plate. Several motors are arranged at corresponding positions on the upper pressing plate. The output shaft of the motors is connected to the gear rollers. The connecting rod is provided with annular teeth along its height direction. When the connecting component passes through the adjusting through holes, the annular teeth mesh with the gear rollers, and the gear rollers drive the connecting component to rise. Within one of the adjustment through holes, there are two positioning components, namely positioning component one and positioning component two, which move along the length direction of adjustment through hole two. The connecting rod is located between positioning component one and positioning component two. Positioning component one and positioning component two each include a rotating shaft, a torsion spring, and a positioning block. The positioning block is rotatably connected to the rotating shaft through the torsion spring. Positioning component two also includes a connecting block. The connecting rod is symmetrically provided with several rows of positioning holes. When the positioning block is inserted into the corresponding positioning hole, an upward force is applied to the connecting piece, preventing the connecting piece from descending. The rotating shaft is perpendicular to the axis of the gear roller.

[0013] Furthermore, it also includes a second linear power component, located inside the upper pressure plate. Two positioning components on one of the upper pressure components use the same set of second linear power components, so that the positions of the two positioning components on one of the upper pressure components are symmetrical. Two positioning components on one of the upper pressure components use the same set of second linear power components, so that the positions of the two positioning components on one of the upper pressure components are symmetrical.

[0014] Furthermore, the suspension mechanism includes a cantilever and a lifting head. The cantilever is used to connect the front support and the rear support, and the lifting head is located at one end of the cantilever and is used to connect the slings.

[0015] A method for using a weightless suspended platform fixing device for high-altitude operations, the method comprising: Step 1: Take the bracket and place it on the structural beam body, aligning the through hole of the bracket with the inserted positioning steel column; Step 2: Place the upper pressure piece on the bracket, pick up the upper pressure piece and fit its opening under the outside of the structural beam body from below. The linear power component drives the two connecting pieces to fit against both sides of the structural beam body. Step 3: Push the upper pressure piece upwards so that both connecting pieces pass through the upper pressure piece. Rotate the lifting block to the outside of the structural beam body. After the person releases their hand, the lifting block sits on the upper pressure plate and pulls the U-shaped piece upwards. Step 4: The linear power component 2 is activated, the upper pressure component is adjusted, and positioning component 1 and positioning component 2 are brought into the working range for fitting and fixing the connecting component; Step 5: The gear roller drives the connecting piece and the lower pressure plate to rise synchronously until the distance between the upper pressure plate and the lower pressure plate is the smallest. The gear roller stops rotating, the positioning block rotates into the positioning groove, and the height of the connecting piece is fixed. This device has completed the fixing of the bracket and the main body of the structural beam. Step 6: Repeat steps 1 to 5 above, installing at least two clamp-type fixing mechanisms on a bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention includes a suspension mechanism located on the structural beam of a building, and a clamp-type fixing mechanism for securing the suspension mechanism and the structural beam together at corresponding points. It changes the traditional method of erecting a counterweight-free suspended platform, eliminating the need for bolts to fix the suspension mechanism to the structural beam, thus reducing damage to the structural beam during construction. It also preserves two supports for the counterweight-free suspended platform, improving its stability. Installing the supports on the existing structural beam allows for the erection of the counterweight-free suspended platform before the roof is fully poured, improving construction efficiency. During the fixing of the supports and the structural beam, the upper clamp and U-shaped fittings are used directly for installation, eliminating the need for repeated manual bolt rotation, reducing the time workers spend at heights, and improving convenience, safety, and efficiency.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-9 .

[0020] This invention provides a weightless suspended basket fixing device for high-altitude operations, including a structural beam body 1 located on a building. Two structural beam bodies 1 arranged side by side form a group, and the group includes a front structural beam body 1 and a rear structural beam body 1. A suspension mechanism, located on the structural beam 1 of the building, is used to suspend the suspension rope and the basket. The suspension mechanism includes a support 2, which includes a front support 21 and a rear support 22. A clamp-type fixing mechanism is used to secure the suspension mechanism and the structural beam body 1 together at corresponding points; the front support 21 is fixed to the front structural beam body 1 by the fixing mechanism, and the rear support 22 is fixed to the rear structural beam body 1 by the fixing mechanism. This changes the traditional method of erecting a suspended platform without counterweight, eliminating the need to use bolts to fix the suspension mechanism to the structural beam body 1, thus reducing damage to the structural beam body 1 during construction.

[0021] A positioning steel bar column 3 is fixed on the structural beam body 1. The bracket 2 is provided with a through hole. The bracket 2 passes through the through hole from the upper end of the positioning steel bar column 3 and is then placed statically on the structural beam body 1. The position of the bracket 2 can be pre-positioned.

[0022] In one embodiment, the clamp-type fixing mechanism includes a double-ended screw 401, a nut 404, and two side-by-side upper clamping plates 402 and lower clamping plates 403. The upper clamping plate 402 is located on the support 2, and the lower clamping plate 403 is located on the structural beam body 1. The double-ended screw 401 includes a first double-ended screw and a second double-ended screw. The double-ended screw 401 passes through the upper clamping plate 402 and the lower clamping plate 403 sequentially from the outside of the structural beam body 1, and is then fixed to the end of the double-ended screw 401 with a nut 404. The upper clamping plate 402, the first double-ended screw, the lower clamping plate 403, and the second double-ended screw, when assembled, form a receiving space that secures the support 2 and the structural beam body 1 together. Two supports 2 are retained for the unbalanced suspended platform to improve the stability of the unbalanced suspended platform erection. By installing the bracket 2 on the original structural beam 1 of the building, the unweighted suspended platform can be erected before the roof is poured, thus improving construction efficiency.

[0023] At this time, the nut 404 at the top of the double-ended screw 401 is attached to the surface of the upper pressure plate 51, and the nut at the bottom of the double-ended screw 401 is attached to the surface of the lower pressure plate 610. The first double-ended screw and the second double-ended screw are respectively attached to both sides of the structural beam body 1, so that the accommodating space is in the most secure state.

[0024] In one embodiment, the clamp-type fixing mechanism includes an upper pressing member 5 and a U-shaped member 6. The U-shaped member 6 includes a lower pressing member 61 and two connecting members 62. The connecting members 62 are symmetrically arranged on the lower pressing member 61. The lower pressing member 61 adjusts the spacing between the two connecting members 62 according to the width of the structural beam body 1, so that the connecting members 62 fit the structural beam body 1. The upper pressing member 5 is used to fix the two connecting members 62, so that the upper pressing member 5, one connecting member 62, the lower pressing member 61, and the other connecting member 62 are assembled to form a receiving space. This receiving space clamps the bracket 2 and the structural beam body 1 together. In the process of fixing the bracket 2 and the structural beam body 1, the upper pressing member 5 and the U-shaped member 6 are directly used to form the receiving space in an outer sleeve manner. After the receiving space is formed, the next U-shaped member 6 can be installed manually. Under the self-control of the upper pressing member 5 and the U-shaped member 6, the receiving space is adjusted to the most suitable state, eliminating the need for manual rotation of bolts for fixing, reducing the time workers spend working at heights, and improving the convenience, safety, and efficiency of use.

[0025] The pressing component 61 includes a pressing plate 610 and a linear power component 611. The pressing plate 610 has symmetrically arranged adjustment through holes 612, and a slidingly connected base plate 613 is embedded at the bottom of each adjustment through hole 612. The linear power component 611 includes a motor 614, which is located on the pressing plate 610. The output shaft of the motor 614 is connected to a bidirectional lead screw 615. A slider 616 is symmetrically arranged on the bidirectional lead screw 615, and a nut 616 adapted to the bidirectional lead screw 615 is provided inside the slider 616. The slider 616 is fixedly connected to the base plate 613, used to control the synchronous movement of the slider 616 and the base plate 613. Specifically, the output shaft of the motor 614 drives the bidirectional lead screw 615 to rotate, and the bidirectional lead screw 615 meshes with the nut 615, causing the slider 616 to translate. The slider 616 then drives the base plate 613 to translate synchronously, allowing the two base plates 613 to move closer or further apart simultaneously according to the width of the structural beam body 1.

[0026] The connector 62 includes a connecting rod 620 and a lifting block 621. The bottom end of the connecting rod 620 extends into the adjustment through hole 612 and is fixed on the base plate 613. The lifting block 621 is rotatably mounted on the top end of the connecting rod 620 and is used to control the connector 62 to pass through the upper pressure member 5 and the supporting U-shaped member 6.

[0027] Before the connector 62 passes through the upper pressure member 5, the length direction of the lifting block 621 is parallel to the length direction of the lower pressure plate 610, and the width of the lifting block 621 is less than the distance between a pair of gear rollers 53, ensuring that the lifting block 621 can smoothly pass through the upper pressure member 5. After the connector 62 passes through the upper pressure member 5, the lifting block 621 is rotated so that the length direction of the lifting block 621 is perpendicular to the length direction of the lower pressure plate 610. In this way, after the hand leaves, the lifting block 621 sits on the upper pressure plate 51, and the lifting block 621 pulls the U-shaped member 6 upward, providing support. The linear power member 611 drives the base plate 613 and the connector 62 to move synchronously, so that the connector 62 fits against the outside of the structural beam body 1 of different specifications.

[0028] In use, take the bracket 2 and place it on the structural beam body 1, aligning the through hole of the bracket 2 with the inserted positioning steel bar column 3. Place the upper pressure piece 5 on the bracket 2, lift the U-shaped piece 6 with the opening facing upward, and move the U-shaped piece 6 upward so that the two connecting pieces 62 move upward from both sides of the structural beam body 1 respectively. Continue to move the U-shaped piece 6 upward so that the upper end of the connecting piece 62 passes through the second adjustment through hole 52. After the lifting block 621 protrudes from above the second adjustment through hole 52, rotate the lifting block 621 so that the length direction of the lifting block 621 is perpendicular to the length direction of the lower pressure plate 610. Remove your hand from the lifting block 621, and the lifting block 621 sits on the upper pressure plate 51. The motor 614 on the lower pressure block drives the slider 616 and the base plate 613 to move, and the two base plates 613 move closer until they are in contact with the outside of the connecting piece 62. Start the second linear power component to drive the upper pressure piece 51. Plate 51 is moved to the center position, and positioning parts 55 and 56 are respectively attached to both sides of connector 62. The output shaft of motor 2 drives gear roller 53 to rotate, and gear roller 53 meshes with ring tooth 54, driving ring tooth 54 and connecting rod 620 to move upward synchronously. During the upward movement, the positioning groove 622 and gap on connector 62 pass through the end of positioning block 562 in sequence. Connecting rod 620 drives base plate 613 and lower pressure plate 610 to move upward synchronously until lower pressure plate 610 is attached to the lower surface of structural beam body 1. At this time, the distance between upper pressure plate 51 and lower pressure plate 610 is the smallest, motor 2 stops rotating, positioning block 562 is inserted into the corresponding positioning groove 622, positioning block 562 points to connecting rod 620, exerting an upward force on connecting rod 620 to prevent connecting rod 620 from descending. Installation is complete.

[0029] The spacing between two adjacent positioning slots 622 is designed based on the common height of the structural beam body 1 and the specifications of the bracket 2. The design ensures that the distance between the upper pressure plate 51 and the lower pressure plate 610 is minimized when the positioning block 562 is finally inserted into the corresponding positioning slot 622. If there is still an error, causing the accommodating space to not fit the lower surface of the structural beam body 1, a shim can be inserted between the lower pressure plate 610 and the structural beam body 1. The shim can be a wooden block.

[0030] The upper pressing member 5 includes an upper pressing plate 51. The upper pressing plate 51 is symmetrically provided with two adjustment through holes 52. A pair of gear rollers 53 are arranged side by side in the horizontal direction inside the adjustment through holes 52. The axis of the gear rollers 53 is parallel to the length direction of the upper pressing plate 51. Several motors are provided at corresponding positions on the upper pressing plate 51. The output shaft of the motors is connected to the gear rollers 53. The connecting rod 620 is provided with annular teeth 54 along its height direction. When the connecting member 62 passes through the adjustment through holes 52, the annular teeth 54 mesh with the gear rollers 53, and the gear rollers 53 drive the connecting member 62 to rise. Within one of the adjustment through holes 52, there are positioning elements 55 and 56 that move along the length of the adjustment through hole 52. The connecting rod 620 is located between the positioning elements 55 and 56. Both the positioning elements 55 and 56 include a rotating shaft 561, a torsion spring, and a positioning block 562. The positioning block 562 is rotatably connected to the rotating shaft 561 through the torsion spring. The positioning element 56 also includes a connecting block 563. The connecting rod 620 is symmetrically provided with several rows of positioning holes. When the positioning block 562 is inserted into the corresponding positioning hole, an upward force is applied to the connecting member 62, preventing the connecting member 62 from descending. The rotating shaft 561 is perpendicular to the axis of the gear roller 53.

[0031] When the positioning block 562 aligns with the positioning groove 622, the torsion spring is in a balanced state as the positioning block 562 enters the positioning groove 622. A gap exists between the two positioning grooves 622 on the connector 62. When the positioning block 562 aligns with the gap, the torsion spring is pushed outward by the gap surface, causing the positioning block 562 to disengage from the positioning groove 622 and fit against the gap surface. After this gap passes the end of the positioning block 562, the positioning groove 622 will reach the positioning block 562 again.

[0032] It also includes a second linear power component, located inside the upper pressure plate 51. Two positioning components 55 on one of the upper pressure components 5 use the same set of second linear power components, so that the positions of the two positioning components 55 on one of the upper pressure components 5 are symmetrical. Two positioning components 56 on one of the upper pressure components 5 use the same set of second linear power components, so that the positions of the two positioning components 56 on one of the upper pressure components 5 are symmetrical.

[0033] The structure of linear power component 2 is the same as that of linear power component 1 611 (this is prior art and is not shown in the figure). The rotating shaft 561 of positioning component 1 55 is connected to the corresponding linear power component 2, and the connecting block 563 of positioning component 2 56 is connected to the corresponding linear power component 2. The purpose of this design is to allow both positioning components 1 55 and both positioning components 2 56 to use the same moving track. During the movement of positioning components 1 55 and positioning components 2 56, the upper pressure component 5 is driven to translate, so that the upper pressure component 5 is in a central position on the structural beam body 1, improving the stability of the force and enhancing the robustness of the device during use.

[0034] Specifically, when the corresponding linear motion component 2 drives positioning component 1 55 and positioning component 2 56 to approach the connecting component 62, if the upper pressure plate 51 is not in the centered position on the structural beam body 1, but in the same adjustment through hole 2 52, one of the positioning component 1 55 and positioning component 2 56 will contact the connecting component 62 first. The one that contacts first continues to move closer to the connecting component 62. Under the action of the reaction force, the upper pressure plate 51 translates until the center of the upper pressure plate 51 is aligned with the center of the connecting component 62. Then, the latter adheres to the outer wall of the connecting component 62, thereby adjusting the upper pressure plate 51 to the centered position on the structural beam body 1. This makes the connection between the upper pressure plate 51 and the structural beam body 1 more secure.

[0035] The suspension mechanism includes a cantilever 11 and a lifting head 12. The cantilever 11 is used to connect the front support 21 and the rear support 22. The lifting head 12 is located at the extended end of the cantilever 11 and is used to connect the sling.

[0036] To improve the stability of the support 2, a wooden pad can be placed on each side of the support 2.

[0037] A method for configuring and using items includes: Step 1: Take the bracket 2 and place it on the structural beam body 1, and align the through hole of the bracket 2 with the inserted positioning steel column 3; Step 2: Place the upper pressure piece 5 on the bracket 2, pick up the upper pressure piece 5 and put its opening under the outside of the structural beam body 1 from below. The linear power component 611 drives the two connecting pieces 62 to fit against both sides of the structural beam body 1. Step 3: Push the upper pressure piece 5 upward so that both connecting pieces 62 pass through the upper pressure piece 5. Rotate the lifting block 621 to the outside of the structural beam body 1. After the person releases their hand, the lifting block 621 sits on the upper pressure plate 51 and the lifting block 621 pulls the U-shaped piece 6 upward. Step 4: The linear power component 2 is in operation, the upper pressure component 5 is adjusted, and the positioning component 1 55 and the positioning component 2 56 are brought into the working range for fitting and fixing the connecting component 62. Step 5: The gear roller 53 drives the connecting piece 62 and the lower pressure plate 610 to rise synchronously until the distance between the upper pressure plate 51 and the lower pressure plate 610 is the smallest. The gear roller 53 stops rotating, the positioning block 562 rotates into the positioning groove 622, and the height of the connecting piece 62 is fixed. This device has completed the fixing of the bracket 2 and the structural beam body 1. Step 6: Repeat steps 1 to 5 above, and install at least two clamp-type fixing mechanisms on a bracket 2.
