Description

Technical Field

[0001] The invention relates to the field of construction engineering, in particular to a hanging basket for structural bottom surface construction and a construction method thereof. Background Art

[0002] A hanging basket is a construction tool used for aerial work in construction projects. During normal operation, it is suspended from the outside of a building and can be used for exterior wall construction, such as curtain wall installation and cleaning. Suspended baskets are not only suitable for building construction but also for bridge construction. They can be suspended from the outside of a bridge deck to provide a platform for workers to perform operations on the deck. Working on the undersides of structures in buildings and bridges has always been a construction challenge, including installing ceilings on the undersides of overhanging buildings and working on the undersides of bridge decks. For this purpose, after lowering the basket, it must be rotated 90 degrees to reach the underside of the structure to allow construction work to proceed. Existing hanging baskets struggle to synchronize their lifting and horizontal movement, often causing them to sway side to side and tilt up and down. This poses significant safety risks and psychological pressure for workers working inside the basket. Furthermore, improperly constructed baskets can damage existing structures. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a hanging basket and a construction method for structural bottom construction, so as to solve the problem that the existing hanging basket often shakes left and right and tilts up and down when constructing below the structural bottom, which brings safety hazards and psychological pressure to the construction workers.

[0004] The technical solution to achieve the above purpose is:

[0005] The present invention provides a hanging basket for structural bottom surface construction, comprising:

[0006] An upper crossbeam, a side close to the structure is provided with a guide wheel, and a lifting mechanism is also provided on the upper crossbeam;

[0007] A positioning mechanism rotatably provided on the upper crossbeam, wherein the positioning mechanism is provided with a movable and adjustable positioning frame;

[0008] a fixed hanging basket rotatably arranged on the upper crossbeam;

[0009] A telescopic hanging basket is movably and adjustable and is arranged in the fixed hanging basket. The telescopic hanging basket can be partially extended to the outside of the fixed hanging basket.

[0010] The hanging basket of the present invention can be hung on the outside of the structure (which can be the facade of a building or the outside of a bridge deck) through a lifting mechanism, and then the positioning mechanism is adjusted by rotation, and then the positioning frame is adjusted by movement. The upper crossbeam can be positioned using the positioning frame, and the guide wheel can roll on the side of the structure (the facade of the building or the outside of the bridge deck). This will not affect the position movement of the hanging basket, but can also improve the stability of the hanging basket, avoid the hanging basket from shaking left and right, tilting up and down, etc., and provide safety for construction workers. The fixed hanging basket and the telescopic hanging basket can not only meet the construction needs of the outer side of the structure, but also can extend below the bottom surface of the structure by rotation to perform construction on the bottom surface of the structure.

[0011] A further improvement of the hanging basket for structural bottom surface construction of the present invention is that the positioning mechanism includes a rotating frame rotatably provided on the upper crossbeam, a first driving mechanism provided on the upper crossbeam and drivingly connected to the rotating frame, and a second driving mechanism provided on the rotating frame and drivingly connected to the positioning frame;

[0012] The first driving mechanism can drive the rotating frame to perform rotation adjustment;

[0013] The positioning frame is movably and adjustablely mounted on the rotating frame;

[0014] The second driving mechanism can drive the positioning frame to move and adjust along the rotating frame.

[0015] A further improvement of the hanging basket for structural bottom construction of the present invention is that an auxiliary positioning track is provided at the edge of the cantilevered portion of the building;

[0016] The positioning frame is provided with a positioning rod that can be extended into the auxiliary positioning track. The upper surface, lower surface and outer side surface of the positioning rod are all provided with freely rolling positioning balls, and there are multiple positioning balls.

[0017] A further improvement of the hanging basket for structural bottom construction of the present invention is that the rotating frame is provided with a guide rail;

[0018] The positioning frame is slidably arranged on the guide rail.

[0019] A further improvement of the hanging basket for structural bottom construction of the present invention is that a counterweight is slidably provided on the bottom of the fixed hanging basket;

[0020] The front end of the counterweight is connected to a first pull rope, which passes over a pulley provided at the front end of the fixed hanging basket and is connected to the rear end of the telescopic hanging basket;

[0021] The rear end of the counterweight is connected to a second pull rope, which passes over a pulley provided at the rear end of the fixed hanging basket and is connected to the rear end of the telescopic hanging basket;

[0022] When the front end of the telescopic hanging basket extends forward from the fixed hanging basket, the second pull rope cooperates with the first pull rope to pull the counterweight block toward the rear end of the fixed hanging basket to balance the fixed hanging basket.

[0023] A further improvement of the hanging basket for structural bottom construction of the present invention is that a plurality of running wheels are provided at the bottom of the telescopic hanging basket, and the telescopic hanging basket can be moved and adjusted along the fixed hanging basket through the provided running wheels.

[0024] A further improvement of the hanging basket for structural bottom surface construction of the present invention is that it also includes a walking mechanism that can be arranged on the structure;

[0025] A lifting rope is wound around the lifting mechanism, and the other end of the lifting rope is connected to the walking mechanism. The lifting mechanism can lift or lower the upper beam by retracting and extending the lifting rope.

[0026] A further improvement of the hanging basket for structural bottom construction of the present invention is that the lifting mechanism is arranged on both sides of the upper crossbeam.

[0027] The present invention also provides a method for constructing a hanging basket for structural bottom surface construction, comprising the following steps:

[0028] Providing auxiliary positioning rails, and fixing the auxiliary positioning rails to the edges of the structure;

[0029] Providing the hanging basket for the construction of the bottom surface of the structure, and hoisting the provided hanging basket for the construction of the bottom surface of the structure to be constructed;

[0030] Rotate and adjust the positioning mechanism toward the bottom surface of the structure so that the positioning mechanism rotates to be perpendicular to the upper beam;

[0031] Lifting the hanging basket for construction on the bottom surface of the structure upwards so that the positioning frame corresponds to the auxiliary positioning rail;

[0032] Move and adjust the positioning frame so that the positioning frame is in contact with the auxiliary positioning rail and the guide wheel provided on the upper beam is in contact with the outer side surface of the structure;

[0033] Rotate and adjust the fixed hanging basket toward the bottom surface of the structure, and rotate the fixed hanging basket to be perpendicular to the upper beam;

[0034] The telescopic hanging basket is extended outwards, and construction is carried out below the cantilevered part of the building through the telescopic hanging basket.

[0035] A further improvement of the construction method of the hanging basket for structural bottom construction of the present invention is that it further comprises:

[0036] providing a running mechanism and placing the running mechanism on the structure;

[0037] Fix the other end of the sling connected to the lifting mechanism to the walking mechanism;

[0038] The hanging basket for bottom surface construction of the structure can be lifted from the ground to the structure to be constructed by retracting the hanging rope through the lifting mechanism;

[0039] When the telescopic hanging basket is used for construction, the walking mechanism is used to walk along the structure and move the hanging basket used for construction on the bottom surface of the structure to the next construction position until the construction at the structure is completed.

[0040] The beneficial effects of the hanging basket for structural bottom surface construction and the construction method thereof of the present invention are:

[0041] The fixed hanging basket of the present invention can be rotated and adjusted relative to the upper crossbeam to meet the construction work requirements of different cantilevered parts. The cantilevered part can be a large cantilevered platform of a building or a bridge deck in a bridge project.

[0042] A positioning mechanism is set up, which can be positioned at the structure through an auxiliary positioning track to ensure that the hanging basket is stable and will not be affected by wind.

[0043] Four hanging points are set, and the fixed hanging basket and the telescopic hanging basket are fixed by connecting pins and the upper crossbeam. The stability of the fixed hanging basket and the telescopic hanging basket is guaranteed during the up and down movement.

[0044] A safety lock and travel switch are set on the upper beam to ensure that the tilt angle of the hanging basket will not exceed the safety angle during movement, the speed will not exceed the set value, and it will not collide with buildings or bridge structures, thus ensuring the safety of the staff.

[0045] The guide wheels provided on the side of the upper crossbeam can roll when in contact with the side of the structure, thereby preventing the hanging basket from directly colliding with the building or bridge structure and causing wear to the building or bridge structure.

[0046] A sliding counterweight is set under the fixed hanging basket. The sliding of the counterweight is controlled by the extension size of the telescopic hanging basket, thereby balancing the fixed hanging basket and the telescopic hanging basket.

[0047] The movement of the walking mechanism can drive the hanging basket to move synchronously, which can facilitate construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0063] See Figure 1The present invention provides a hanging basket for structural bottom surface construction and a construction method thereof, which are used to solve the problems that the existing hanging basket needs to be rotated 90° when constructing cantilevered parts, making it difficult to maintain synchronization between the lifting and horizontal displacement of the hanging basket, and the hanging basket often shakes left and right, tilts up and down, etc., which brings safety hazards and psychological pressure to the construction workers. The hanging basket of the present invention is provided with a positioning mechanism, and the positioning mechanism and guide wheels are used to position the hanging basket, ensuring that the hanging basket is stable and will not shake due to the influence of wind, thereby improving the safety of the operation. The hanging basket of the present invention is suitable for building construction and bridge engineering construction. The hanging basket for structural bottom surface construction of the present invention and the construction method thereof are described below with reference to the accompanying drawings.

[0064] See Figure 1 , showing a side view of the use state of the hanging basket for bottom surface construction of the structure of the present invention. Figure 2 , showing a three-dimensional structural diagram of the present invention in use for the bottom surface construction of the structure of the hanging basket. Figure 3 , shows a schematic diagram of the three-dimensional structure of the connection between the upper crossbeam of the hanging basket used for bottom surface construction of the present invention and the fixed hanging basket and the telescopic hanging basket. Figures 1 to 3 , the hanging basket used for the bottom surface construction of the structure of the present invention is described.

[0065] like Figures 1 to 3 As shown, the hanging basket for structural bottom construction of the present invention comprises an upper crossbeam 21, a positioning mechanism 22, a fixed hanging basket 23 and a telescopic hanging basket 24. A guide wheel 211 is provided on the side of the upper crossbeam 21 close to the structure, and a lifting mechanism 212 is also provided on the upper crossbeam 21; the positioning mechanism 22 is rotatably provided on the upper crossbeam 21, and is combined with the upper crossbeam 21 to form a fixed hanging basket. Figure 7 As shown, the positioning mechanism 22 is provided with a movable and adjustable positioning frame 221; the fixed hanging basket 23 is rotatably provided on the upper beam 21, and the telescopic hanging basket 24 is movably and adjustably provided in the fixed hanging basket 23, and the telescopic hanging basket 24 can be partially extended to the outside of the fixed hanging basket 23.

[0066] The working principle of the hanging basket for structural bottom construction of the present invention is as follows:

[0067] When in use, the upper crossbeam 21 and the positioning mechanism 22 connected to the upper crossbeam 21, the fixed hanging basket 23 and the telescopic hanging basket 24 can be hung on the outside of the structure through the lifting mechanism 212. The structure can be a building or a bridge. The upper crossbeam 21 is arranged horizontally. The upper crossbeam 21 is lifted to correspond to the bottom surface of the structure to be constructed by the lifting mechanism 212. The ground of the structure to be constructed can be the bottom surface of the cantilevered part or the bottom surface of the bridge deck. The positioning mechanism 22 is then rotated 90 degrees toward the structure 11 so that the positioning mechanism 22 is perpendicular to the upper crossbeam 21. The upper crossbeam 21 is then lifted upward so that the positioning frame 221 on the positioning mechanism 22 corresponds to the structure 11. The positioning mechanism 22 is then lifted upward so that the positioning frame 221 on the positioning mechanism 22 corresponds to the structure 11. The positioning frame 221 positions the upper beam 21. For example, the positioning frame 221 can be placed close to the bottom surface of the structure 11, and the upper beam 221 can be positioned through the friction resistance of the positioning frame 221. When the positioning frame 221 is moved and adjusted, the guide wheel 211 provided on the upper beam 21 can be in contact with the outer side surface of the structure. When constructing the cantilevered part of the building, the guide wheel 211 is in contact with the outer side surface of the cantilevered part of the building; when constructing the bridge deck of the bridge, the guide wheel 211 is in contact with the side of the bridge deck, which can further limit the upper beam 21, improve the structural stability of the upper beam 21, and thereby improve the stability of the fixed hanging basket 23 and the telescopic hanging basket 24. Then, the fixed hanging basket 23 is rotated toward the structure 11, and the fixed hanging basket 23 is rotated to be perpendicular to the upper beam 21, and then the telescopic hanging basket 24 is extended outward. The telescopic hanging basket 24 is located below the structure 11 and can provide a construction work platform for the construction at the structure 11. The materials for construction can be placed in the telescopic hanging basket 24 in advance, and the construction personnel can also enter the telescopic hanging basket 24 in advance, and then use the telescopic hanging basket 24 to carry out construction on the structure 11.

[0068] In a specific embodiment of the present invention, Figure 3 and Figure 7 As shown, the positioning mechanism 22 includes a rotating frame 222 rotatably arranged on the upper beam 21, a first driving mechanism 223 arranged on the upper beam 21 and drivingly connected to the rotating frame 222, and a second driving mechanism 224 arranged on the rotating frame 222 and drivingly connected to the positioning frame 221; the first driving mechanism 223 can drive the rotating frame 222 to rotate and adjust; the positioning frame 221 is movably and adjustable on the rotating frame 222; the second driving mechanism 224 can drive the positioning frame 221 to move and adjust along the rotating frame 222.

[0069] When positioning is performed using the positioning mechanism 22, the upper beam 21 is lifted to the corresponding position of the structure by the lifting mechanism 212, and then the first driving mechanism 223 is used to drive the rotating frame 222 to rotate 90° toward the structure 11, and then the second driving mechanism 224 drives the positioning frame 221 to move and adjust along the moving frame 222. Initially, the positioning frame 221 can be located at the end of the rotating frame 222, so at this time it can be moved and adjusted in the direction close to the upper beam 21 to facilitate positioning of the positioning frame 221.

[0070] In a preferred embodiment, as Figure 3 、 Figures 7 to 9 As shown, the first drive mechanism 223 includes a first motor 2231 mounted on the upper crossbeam 21 and a drive gear 2232 connected to the motor shaft of the first motor 2231. A power gear 2221 is fixedly connected to the rotating frame 222. The drive gear 2232 meshes with the power gear 2221, and the first motor 2231 drives the drive gear 2232 to rotate. The drive gear 2232 then rotates the power gear 2221, thereby driving the rotating frame 222 to rotate. Furthermore, a bearing is fixedly connected to the interior of the power gear 2221, and the inner ring of the bearing is fixedly connected to the bottom of the upper crossbeam 21. In this way, the power gear 2221 and the rotating frame 222 can rotate relative to the upper crossbeam 21.

[0071] In another preferred embodiment, the first drive mechanism 223 is a motor fixedly connected to the upper crossbeam 21, and the motor shaft of the motor is connected to the rotating frame 222. The motor can then directly drive the rotating frame 222 to rotate via the motor shaft. The motor preferably has a locking function, that is, it can lock the position of the rotating frame 222 after the rotation is adjusted.

[0072] Furthermore, if Figure 1 and Figure 2 As shown, the edge of the structure 11 is provided with an auxiliary positioning track 25; when constructing the cantilevered part of the building, the auxiliary positioning track 25 can be fixedly connected to the edge of the cantilevered part; when constructing the bridge deck of the bridge, the auxiliary positioning track 25 can be fixedly connected to the edge of the bridge deck; Figures 7 to 9 As shown, the positioning frame 221 is provided with a positioning rod 2211 that can extend into the auxiliary positioning track 25. The upper surface, lower surface and outer side surface of the positioning rod 2211 are all provided with freely rotatable positioning balls 2212, and there are multiple positioning balls 2212.

[0073] In this way, when the positioning frame 221 is used to position the upper beam 21, the rotating frame 222 is first rotated 90 degrees toward the structure 11, and then the upper beam 21 is lifted by the lifting mechanism 212, so that the positioning rod 2211 corresponds to the auxiliary positioning track 25, and then the second driving mechanism 224 is used to drive the positioning frame 221 toward the direction close to the upper beam 21, so that the positioning rod 2211 extends into the auxiliary positioning track 25. When the positioning ball 2212 on the outer side of the positioning rod 2211 contacts the auxiliary positioning track 25, the second driving mechanism 224 is used to drive the positioning frame 221 to move toward the direction close to the upper beam 21. The driving mechanism 224 continues to drive the positioning frame 221 to move, and at this time, the upper beam 21 can be pulled to move toward the structure until the guide wheel 211 is in contact with the outer side of the structure. At this time, the second driving mechanism 224 stops running, and the guide wheel 211 and the positioning rod 2211 clamp the upper beam 21 and position it at the structure 11, which can ensure the stability of the upper beam 21, and thus ensure the structural stability of the fixed hanging basket 23 and the telescopic hanging basket 24 connected to the upper beam 21, so that they will not be affected by the wind and shake, thereby ensuring the construction safety of the workers.

[0074] Furthermore, if Figure 7 and Figure 9 As shown, a pair of photoelectric docking switches 225 are provided on the rotating frame 222, and the pair of photoelectric docking switches 225 are used to detect whether the positioning rod 2211 corresponds to the auxiliary positioning rail 25. One of the pair of photoelectric docking switches 225 is set close to the positioning frame 221, and the other is set away from the positioning frame 221. Initially, one photoelectric docking switch 225 can detect the infrared rays emitted by the other photoelectric docking switch. When the crossbeam 21 is lifted on the lifting mechanism 212, the positioning rod 2211 corresponds to the auxiliary positioning rail 25, and the auxiliary positioning rail 25 blocks the photoelectric docking switch 225, so that the photoelectric docking switch 225 cannot detect the infrared rays emitted by the other photoelectric docking switch, indicating that the lifting action is in place at this time, and the lifting mechanism 212 is controlled to stop running.

[0075] Furthermore, the auxiliary positioning rail 25 is preferably U-shaped, with the opening of the U-shaped auxiliary positioning rail 25 facing the inner side of the structure, and the U-shaped auxiliary positioning rail is fixed to the edge of the structure 11 by bolts. The auxiliary positioning rail 25 is preferably a channel steel. In another preferred embodiment, the auxiliary positioning rail 25 is L-shaped, including a vertical plate and a horizontal plate connected to the vertical plate. The vertical plate can be partially attached to the outer side of the structure 11 and then fixedly connected to the structure 11 by bolts. The horizontal plate is located below the structure 11. In another preferred embodiment, the auxiliary positioning rail 25 is an I-beam.

[0076] Furthermore, if Figures 7 to 9As shown, the rotating frame 222 is provided with guide rails 2222; the positioning frame 221 is slidably mounted on the guide rails 2222. Preferably, two guide rails 2222 are provided, located on either side of the bottom surface of the rotating frame 222. The positioning frame 221 also includes a base plate 2213. The base plate 2213 has guide rail seats corresponding to the guide rails 2222, which are clamped onto the corresponding guide rails 2222. The guide rails 2222 serve as a limiting guide for the movement and adjustment of the positioning frame 221.

[0077] In a preferred embodiment, as Figures 7 to 9 As shown, the second driving mechanism 224 includes a second motor 2241 provided on the rotating frame 222 and a rotating gear 2242 connected to the motor shaft of the second motor 2241; a rack 2214 is connected to the bottom of the positioning frame 221, and the rotating gear 2242 is engaged with the rack 2214. The second motor 2241 can drive the rotating gear 2242 to rotate, and the rotation of the rotating gear 2242 drives the rack 2214 to move, and then the rack 2214 moves with the positioning frame 221, thereby driving the positioning frame 221 to move and adjust.

[0078] In another preferred embodiment, the second driving mechanism 224 is a driving cylinder or an electric cylinder provided on the rotating frame 222, and the driving cylinder or the electric cylinder is connected to the positioning frame 221, and then moves and adjusts the positioning frame 221 through telescoping.

[0079] Furthermore, the positioning frame 221 further includes a support rod 2215 supported on the bottom plate 2213. The end of the support rod 2215 is connected to the positioning rod 2211. The support rod 2215 is preferably in an inverted L shape. The number of support rods 2215 can be one or more. The positioning rod 2211 is preferably a square rod.

[0080] In a specific embodiment of the present invention, Figure 10 and Figure 12 As shown, a counterweight block 261 is slidably provided at the bottom of the fixed hanging basket 23; the front end of the counterweight block 261 is connected to a first pull rope 262, which passes over the pulley 243 set at the front end of the fixed hanging basket 23 and is connected to the rear end of the telescopic hanging basket 24; the rear end of the counterweight block 261 is connected to a second pull rope 263, which passes over the pulley 232 set at the rear end of the fixed hanging basket 23 and is connected to the rear end of the telescopic hanging basket 24; when the front end of the telescopic hanging basket 24 extends forward from the fixed hanging basket 23, the second pull rope 263 and the first pull rope 262 cooperate to pull the counterweight block 261 toward the rear end of the fixed hanging basket 23 to balance the fixed hanging basket 23.

[0081] When the telescopic hanging basket 24 moves toward the fixed hanging basket 23 , the first pull rope 262 pulls the counterweight 261 toward the front end of the fixed hanging basket 23 , thereby resetting the counterweight 261 .

[0082] Preferably, a chute is provided at the bottom of the fixed hanging basket 23, and rollers are provided on both sides of the counterweight block 261, and the counterweight block 261 is slidably arranged in the chute via the rollers.

[0083] Furthermore, the bottom of the telescopic basket 24 is provided with a plurality of running wheels 241, which enable the telescopic basket 24 to be moved and adjusted along the fixed basket 23. The telescopic basket 24 is preferably provided with a drive motor connected to at least one of the running wheels 241. A worker can activate the drive motor to rotate the running wheels 241, thereby extending the telescopic basket 24 outward. Preferably, the drive motor is located at the rear side of the telescopic basket 24.

[0084] Furthermore, a plurality of running wheels 241 are also provided on the top of the telescopic hanging basket 24 .

[0085] Furthermore, both the fixed hanging basket 23 and the telescopic hanging basket 24 are structures with a top opening, including a platform plate and fences erected on three sides of the platform plate. The outer contours of the fixed hanging basket 23 and the telescopic hanging basket 24 are rectangular, and the size of the telescopic hanging basket 24 is smaller than that of the fixed hanging basket 23. The front side of the fixed hanging basket 23 is provided with an opening to facilitate the extension of the telescopic hanging basket 24, and the rear side of the telescopic hanging basket 24 is provided with an opening.

[0086] A connecting frame 231 is provided on the top of the fixed hanging basket 23 , and the connecting frame 231 is used to connect to the upper crossbeam 21 .

[0087] In a specific embodiment of the present invention, Figure 5 and Figure 6 As shown, a rotating member 215 is provided at the bottom of the upper crossbeam 21, and the rotating member 215 is connected to the connecting frame 231 of the fixed hanging basket 23. The rotating member 215 can be rotated and adjusted, and can then be rotated and adjusted together with the fixed hanging basket 23. The rotating member 215 can be a rotating cylinder, or a rotatable mechanism composed of a motor and gears.

[0088] Furthermore, limit frames 216 are provided on both end sides of the upper beam 21 corresponding to the telescopic hanging basket 24 and the fixed hanging basket 23. The limit frames 216 are connected to the telescopic hanging basket 24 and the fixed hanging basket 23 by connecting pins 217. Before the fixed hanging basket 23 is rotated and adjusted, the connecting pins 217 are passed through the connecting limit frames 216 and the corresponding fences on the telescopic hanging basket 24 and the fixed hanging basket 23, thereby realizing the limited fixation of the telescopic hanging basket 24 and the fixed hanging basket 23 to the upper beam 21. When the fixed hanging basket 23 is rotated and adjusted, the connecting pins 217 need to be pulled out to release the limit on the telescopic hanging basket 24.

[0089] like Figure 10 and Figure 11As shown, a pin hole 242 is provided at the top of the fence on the front side of the telescopic hanging basket 24, and a pin hole 233 is provided at the fence on the rear side of the fixed hanging basket 23. The pin holes 242 and 233 are used to connect corresponding connecting pins 217.

[0090] In a specific embodiment of the present invention, Figure 1 、 Figure 2 and Figure 13 As shown, the hanging basket for structural bottom construction of the present invention also includes a walking mechanism 27 that can be arranged at the structure; Figure 3 and Figure 4 As shown, a lifting rope 28 is wound around the lifting mechanism 212 , and the other end of the lifting rope 28 is connected to the walking mechanism 27 . The lifting mechanism 212 can lift or lower the upper beam 21 by retracting and extending the lifting rope 28 .

[0091] When constructing a cantilevered portion of a building, the traveling mechanism 27 can be installed on the building's roof 12 and can travel on the roof. The traveling mechanism 27 can move the upper beam 21, the fixed hanging basket 23, and the telescopic hanging basket 24 laterally along the building's outer side surface via the suspension rope 28, thereby moving the fixed hanging basket 23 and the telescopic hanging basket 24 to the next construction location. When constructing a bridge deck, the traveling mechanism 27 can be placed on the deck and can travel on the deck.

[0092] In a preferred embodiment, the traveling mechanism 27 includes a base frame 271, rollers 273 mounted on the base frame 271, and a support frame 272 mounted upright on the base frame 271. Fixed pulleys are mounted on the support frame 272, and the suspension rope 28 passes over the corresponding fixed pulleys before being fixedly connected to the support frame 272. To improve the balance of the support frame 272, a counterweight 276 is provided on the side of the support frame 272 facing away from the exterior of the building. A support plate 274 is provided on the side of the support frame 272 facing the exterior of the structure. The end of the support plate 274 is connected to a rotatable guide wheel 275, which abuts against the wall at the edge of the building roof 12 or against the structure at the edge of the bridge deck. The traveling mechanism 27 can be manually propelled or driven by a motor connected to the rollers 273 on the base frame 271. The motor is then activated to drive the rollers 273, thereby achieving movement of the traveling mechanism 27.

[0093] In another preferred embodiment, the walking mechanism 27 includes an edge guide rail provided on the structure and a moving trolley slidably provided on the guide rail. The moving trolley can be moved and adjusted along the guide rail. The end of the lifting rope 28 connected to the lifting mechanism 212 is fixedly connected to the moving trolley, so that the movement adjustment of the moving trolley can be carried out with the lifting rope 28, the upper beam 21, the fixed hanging basket 23 and the telescopic hanging basket 24.

[0094] Furthermore, if Figure 5 and Figure 6 As shown, the lifting mechanisms 212 are provided on both sides of the upper crossbeam 21. Two lifting mechanisms 212 are provided on each side of the upper crossbeam 21 to improve the safety of the hanging basket.

[0095] A travel switch 214 and a safety lock 213 are respectively provided on both ends of the upper crossbeam 21. The travel switch is used to detect the upward stroke of the upper crossbeam 21, and the safety lock 214 is used for the suspension rope 28 to pass through, thereby playing a role of safety limit for the suspension rope 28.

[0096] The upper crossbeam 21 is preferably a truss structure, and can also be a steel beam. The lifting mechanism 212 is provided on the corresponding limiting frame 216.

[0097] The following describes the use of the hanging basket for structural bottom construction of the present invention.

[0098] First, fix the auxiliary positioning rail to the edge of the structure with bolts, so that the slots of the auxiliary positioning rail face the inside of the structure.

[0099] The walking mechanism is well arranged on the structure, and the lifting rope passes through the safety lock of the upper beam and is connected to the lifting mechanism. When the lifting mechanism is started, the lifting rope can be curled or released.

[0100] The staff enters the telescopic hanging basket, loads tools and materials into the telescopic hanging basket, fixes the telescopic hanging basket and the fixed hanging basket to the upper beam through connecting pins, starts the lifting mechanism, and lifts the fixed hanging basket and the telescopic hanging basket from the ground.

[0101] When the fixed hanging basket and the telescopic hanging basket are lifted to the position of the structure to be constructed, the positioning mechanism rotates and adjusts 90 degrees and is located at the lower part of the bottom surface of the structure. The lifting mechanism continues to lift the hanging basket until the photoelectric docking switch detects the auxiliary positioning rail. The lifting mechanism stops lifting, and the second driving mechanism drives the positioning rod close to the auxiliary positioning rail until the positioning ball contacts the auxiliary positioning rail and the guide wheel of the upper beam contacts the cantilevered part of the building. At this time, the upper beam is in a stable state and will not be affected by the wind.

[0102] The fixed hanging basket rotates 90 degrees via a rotating member and enters the lower part of the structure. The extension of the telescopic hanging basket is controlled according to the actual construction scope. The telescopic hanging basket provides a construction platform for workers to use to carry out construction on the bottom surface of the structure. This construction can be done for ceiling construction at the bottom of the building's cantilevered part, such as installing decorative panels on the underside of the cantilevered part, or for bolting and welding the bottom of the bridge deck.

[0103] After the construction at the current position is completed, the walking mechanism drives the hanging basket to move, and the positioning ball moves in the auxiliary positioning track until the next construction is completed.

[0104] After the construction of the current part is completed, the telescopic hanging basket is retracted, the positioning mechanism is retracted, and the lifting mechanism lifts the hanging basket to the next part for construction.

[0105] The present invention also provides a construction method of a hanging basket for structural bottom surface construction, and the construction method is described below.

[0106] like Figure 14 As shown, the construction method of the present invention comprises the following steps:

[0107] Execute step S101, provide an auxiliary positioning rail, and fix the auxiliary positioning rail to the edge of the structure; then execute step S102;

[0108] Execute step S102, provide a hanging basket for structural bottom surface construction, and hoist the provided hanging basket for structural bottom surface construction to the structure to be constructed; then execute step S103;

[0109] Execute step S103, rotate and adjust the positioning mechanism toward the bottom surface of the structure, so that the positioning mechanism rotates to be perpendicular to the upper beam; then execute step S104;

[0110] Execute step S104, lift the hanging basket for the bottom surface construction upwards so that the positioning frame corresponds to the auxiliary positioning track; then execute step S105;

[0111] Execute step S105, move and adjust the positioning frame so that the positioning frame is in contact with the auxiliary positioning rail and the guide wheel provided on the upper crossbeam is in contact with the outer side surface of the structure; then execute step S106;

[0112] Execute step S106, rotate and adjust the fixed hanging basket toward the bottom surface of the structure, and rotate the fixed hanging basket to be perpendicular to the upper beam; then execute step S107;

[0113] Execute step S107, extend the telescopic hanging basket outward, and construct the bottom surface of the structure through the telescopic hanging basket.

[0114] In a specific embodiment of the present invention, the construction method of the present invention further comprises:

[0115] Provide running gear and place the running gear on the structure;

[0116] Fix the other end of the sling connected to the lifting mechanism to the walking mechanism;

[0117] The hanging basket used for bottom surface construction of the structure can be lifted from the ground to the structure to be constructed by retracting the lifting rope through the lifting mechanism;

[0118] When using the telescopic hanging basket for construction, the walking mechanism is used to walk along the roof of the building and move the hanging basket used for construction on the bottom surface of the structure to the next construction position until the construction at the structure is completed.

[0119] In a specific embodiment of the present invention, the construction method of the present invention further comprises:

[0120] A photoelectric docking switch is set on the positioning mechanism. When the hanging basket used for construction on the bottom surface of the structure is lifted upward to make the positioning frame correspond to the auxiliary positioning track, the photoelectric docking switch is used to determine whether the positioning frame corresponds to the auxiliary positioning track. After the photoelectric docking switch detects the auxiliary positioning track, the lifting mechanism is controlled to stop lifting.

[0121] In a specific embodiment of the present invention, the construction method of the present invention further comprises:

[0122] The positioning frame is provided with a positioning rod which can be extended into the auxiliary positioning track. The upper surface, lower surface and outer side surface of the positioning rod are all provided with freely rolling positioning balls which can roll in the auxiliary positioning track.
