Description

Technical Field

[0001] The present application relates to the field of building construction equipment, and in particular to a reverse-supported roof beam-riding hanging basket and a construction method thereof. Background Art

[0002] In roof construction and aerial work, hanging baskets are widely used as a common equipment in work scenarios such as cleaning, maintenance and decoration of building exterior walls. At present, the most common hanging baskets on the market realize basic support functions through simple rigid cantilever brackets combined with counterweights.

[0003] However, the above conventional measures cannot adapt well to different types of roof environments. The cantilever mechanism cannot adapt to different building environments such as parapets and building cantilever beams at the same time. Especially when faced with complex geometric shapes or limited space, it is impossible to apply counterweights. Traditional solutions often lack sufficient flexibility, resulting in operational difficulties and even increased safety hazards. Different cantilever mechanisms need to be replaced when encountering different building environments, which not only affects construction efficiency, but also brings greater pressure to site management and risk prevention and control. In this case, how to effectively overcome the operational inconvenience caused by terrain differences becomes an urgent problem to be solved. Summary of the invention

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a reverse-supported roof beam hanging basket and a construction method thereof.

[0005] Two groups of cantilever mechanisms are arranged in parallel, each group of the cantilever mechanisms comprises a cantilever bracket, a cantilever beam vertically fixed to the cantilever bracket and a steel cable, the cantilever beam and the cantilever bracket form a "cross" structure, the steel cable is set on the top of the cantilever bracket, the steel cable, the cantilever bracket and the cantilever beam form a triangular structure, one end of each cantilever beam is equipped with a hoisting rope, and the two groups of hoisting ropes are used to hoist the hanging basket together; Two groups of adjustment devices are arranged in parallel, each group of the adjustment devices includes a pre-embedded counterweight plate, an adjustable counterweight plate and a support, the pre-embedded counterweight plate and the adjustable counterweight plate are both connected by rotatable splicing of multiple plates, the lower surface of the pre-embedded counterweight plate is fixed to a first preset position of the building structure, the upper surface of the adjustable counterweight plate is fixed to the bottom of the cantilever bracket, the lower surface of the adjustable counterweight plate is fixed to a second preset position of the building structure, one end of the support beam is rotatably connected to the cantilever beam, and the other end is fixed to the upper surface of the pre-embedded counterweight plate, and the length of the support beam can be adjusted.

[0006] By adopting the above scheme, when the cantilever mechanism is carried on a complex building surface, it is difficult to find the counterweight point, and the counterweight plate cannot fully contact the building surface. There are too few connection points between the counterweight plate and the building surface, which leads to excessive force on the local part of the building surface, which is easy to damage the wall and cause the counterweight plate to fall off, causing safety hazards. The embedded counterweight plate and the adjustable counterweight plate are designed to be a structure composed of multiple plates that are rotated and spliced. The embedded counterweight plate and the adjustable counterweight plate can adapt to the inclined building surface bent at a certain angle, so as to fully contact the building surface. Since the support beam is rotatably connected to the cantilever beam and the length is adjustable, when the embedded counterweight plate is carried on a complex building surface, the support beam can still find a suitable support angle.

[0007] In one embodiment, the building structure is a floor beam, and the adjustment device also includes an adjustment beam, the adjustment beam includes a mounting channel steel and an adjustment slide rail, the mounting channel steel is located at both ends of the adjustment slide rail, the adjustment slide rail includes two detachable sections, and the side surface of the mounting channel steel is linearly arrayed along its length direction to cooperate with the adjustment slide rail. The lower surface of the embedded counterweight plate is fixed to the upper surface and side surface of the first floor beam, and the lower surface of the adjustment counterweight plate is fixed to the side surface and bottom surface of the second floor beam. The first floor beam and the second floor beam are cantilever beams included in two adjacent floors, and the first floor beam is located directly below the second floor beam.

[0008] By adopting the above scheme, when the hoisting rope lifts the hanging basket, the cantilever mechanism tends to tilt in the direction of the hanging basket, and the support rod provides tension to the end of the cantilever beam away from the counterweight rope to balance the tension provided by the hanging basket. At this time, the support rod applies tension to the embedded counterweight plate, and the embedded counterweight plate and the adjustable counterweight plate are fixedly connected to the two surfaces of the floor beam. The bottom surface of the first floor beam will provide shear force to the embedded counterweight plate, and the side surface of the second floor beam will provide shear force to the adjustable counterweight plate, thereby making the connection between the counterweight plate and the floor beam more secure.

[0009] In one embodiment, the adjusting beam includes a mounting channel steel and an adjusting slide rail, the building structure is a parapet, the embedded counterweight plate is fixed to the wall surface of the parapet, the adjusting counterweight plate is bent and fixed to the top surface and the wall surface of the parapet, the two ends of the adjusting beam are respectively fixed to the side surfaces of the adjusting counterweight plate and the embedded counterweight plate, and the bottom surface of the adjusting beam is attached to the wall of the parapet.

[0010] By adopting the above solution, when the cantilever mechanism is supported on the top surface of the parapet, since the embedded counterweight plate and the adjustable counterweight plate are both fixed to the wall, they lose the reinforcement of the shear force and are easy to fall off the wall. The contact area between the adjusting mechanism and the wall is increased by setting the adjusting beam, and more fixing points are provided, thereby strengthening the connection between the counterweight plate and the wall.

[0011] In one embodiment, the building structure is a horizontal roof surface, and the support beam includes a mounting sleeve and a support inner rod. The length of the support inner rod is adjustable and can be folded from the middle. The folded support inner rod can be accommodated in the mounting sleeve. The side surface of the mounting sleeve has a first mounting hole that is arranged in a linear array along its length direction and cooperates with the support inner rod. The embedded counterweight plate, the adjustable counterweight plate and the adjustable beam are all fixed to the horizontal roof surface, and the support beam is perpendicular to the embedded counterweight plate.

[0012] By adopting the above scheme, the inner support rod moves in the mounting channel steel and can be fixed to the mounting channel steel through the first mounting hole, so that the overall length of the support beam can be changed to adapt to different support effects. When the cantilever mechanism is supported on the horizontal roof surface, the embedded counterweight plate can carry the counterweight block, and the force direction of the support shaft is the same as the gravity direction, which is convenient for the staff to balance the weight.

[0013] In one of the embodiments, the upper surface of the adjusting counterweight plate carries a first driving gear, sliding grooves cooperating with the adjusting slide rail are provided on both sides of the adjusting counterweight plate, a first driving rack cooperating with the first driving gear is provided inside the adjusting slide rail, a sliding mechanism is provided at the bottom of the adjusting counterweight plate, the sliding mechanism can slide in any direction, a plurality of mounting ears are provided on the side of the mounting channel steel and a second driving rack is provided inside, both ends of the adjusting slide rail can carry the second driving gear, when the cantilever mechanism is carried on a horizontal roof surface, the mounting channel steel is perpendicular to the adjusting slide rail, the second driving gear can cooperate with the second driving rack, and a bidirectional pulley is provided at the bottom of the adjusting slide rail.

[0014] By adopting the above scheme, when the cantilever mechanism is carried on the horizontal roof surface, the cantilever mechanism needs to be moved frequently during the installation process of the cantilever mechanism in order to move the cantilever mechanism to the best working position. Before fixing the cantilever mechanism, the mounting channel steel is first fixed to the ground through the mounting ears. The two mounting channel steels are parallel to the edge of the roof. The mounting channel steels are fixed to the two ends of the adjusting slide rail. The second driving gear cooperates with the second driving rack. When the second gear is driven, the cantilever mechanism can be moved autonomously in the direction in which the mounting channel steel extends. By arranging a rack inside the adjusting slide rail, the first driving gear is started before the position of the cantilever mechanism is fixed. The cantilever mechanism can slide along the direction in which the adjusting track extends under the drive of the adjusting counterweight plate, so that it can be accurately adjusted to the best working position.

[0015] In one embodiment, the hanging basket includes a bottom plate, a guardrail fixed on the bottom plate, and an auxiliary device located outside the guardrail. A lifting device connected to the lifting rope is provided inside the guardrail. The auxiliary device includes an auxiliary frame and an auxiliary pedal located inside the auxiliary frame. The auxiliary pedal protrudes from the inner wall surface of the guardrail. Stop racks are provided on the inner walls on both sides of the auxiliary frame. Stop blocks are provided on both sides of the auxiliary pedal, and the stop blocks can cooperate with the stop rack.

[0016] By adopting the above scheme, the hanging basket realizes the change of up and down position through the lifting device, but the lifting device cannot accurately control the lifting height, and frequent opening and closing of the lifting device is likely to cause failure of the lifting device, thereby causing safety hazards. By arranging an auxiliary device on the hanging basket, the staff can adjust the height of the auxiliary pedal, and then fix the auxiliary pedal. The staff can stand on the auxiliary pedal to work, so that they can fine-tune their height, achieving the effect of flexible operation.

[0017] In one of the embodiments, a stop assembly is provided in the stop block, and the stop assembly includes a wedge-shaped pressing block, a wedge-shaped sliding block, a locking block and a second elastic member, the wedge-shaped pressing block passes through the top of the stop block, the wedge-shaped sliding block is located in the stop block and cooperates with the wedge-shaped surface of the wedge-shaped pressing block, the locking block is fixed to the side of the wedge-shaped sliding block away from the wedge-shaped pressing block, the locking block passes through the side of the stop block and cooperates with the stop rack, and one end of the second elastic member is fixed to the inner wall surface of the stop block, and the other end is fixed to the side of the wedge-shaped sliding block away from the locking block.

[0018] By adopting the above scheme, after the staff slides the stop block to an appropriate height, they press the wedge-shaped pressing block, and the wedge-shaped sliding block will drive the locking block to shift, and the locking block cooperates with the stop rack to achieve locking. When the staff needs to readjust the height, they can pull the wedge-shaped pressing block upward, and the second elastic member can pull the wedge-shaped sliding block to reset, and the locking block will disengage from the stop rack, thereby avoiding the staff from repeatedly disassembling and adjusting the height.

[0019] In one of the embodiments, a rotating shaft is passed through the middle of the auxiliary pedal, and the auxiliary pedal can rotate around the rotating shaft. A stop surface is provided on the rotating shaft, and a stop gear is provided between the auxiliary pedal and the stop block. A stop recess that cooperates with the stop gear is provided on the side of the auxiliary pedal, and the stop block and the stop gear both cooperate with the stop surface. A storage groove is provided on the bottom plate, and sliding grooves are provided on both sides of the storage groove. A rotating shaft is passed through the bottom of the auxiliary frame, and the auxiliary frame can slide into the hanging basket along the storage groove after being flipped around the rotating shaft.

[0020] By adopting the above solution, when the workers need other work tools during work, they need to lower the hanging basket to the ground to get them. If the workers on the working floor hand them over during the construction process, it is an illegal operation and there is a safety hazard. Through the setting of the auxiliary frame, the auxiliary frame can be folded, and the workers on the working floor can place the tools in the tool carrying slot of the auxiliary frame, and then slide the tool carrying slot into the storage slot, which is convenient for the workers to take the tools from the working floor and reduces safety hazards.

[0021] In one embodiment, a detachable support rod is provided between the guardrail and the auxiliary frame, and the two ends of the support rod are rotatably connected to the side walls of the guardrail and the auxiliary frame respectively. The support rod can be rotated to any angle and fixed, and a suction cup is provided on the side of the auxiliary pedal away from the guardrail.

[0022] By adopting the above scheme, the hanging basket will swing when encountering strong winds. There is a risk of the hanging basket colliding with the installed glass curtain wall during the swinging process. By arranging the suction cup on the auxiliary pedal, when the hanging basket collides, the suction cup and the wall will play a buffering role to avoid a strong collision between the hanging basket and the curtain wall, which may cause the hanging basket to smash the curtain wall. At the same time, in strong winds, the suction cup can absorb the curtain wall to prevent the hanging basket from swinging and causing safety hazards. The support rod can make the auxiliary device offset to the surface where the curtain wall is located, which not only prevents the entire hanging basket from colliding with the curtain wall, but also increases the controllable distance of the suction cup to ensure that the suction cup can absorb the wall.

[0023] A construction method for a reverse-supported roof beam hanging basket comprises the following steps: S1: The building structure is a horizontal roof surface. First, the mounting channel steel is fixed on the horizontal roof surface through the mounting ears. The two sections of the mounting channel steel are arranged in parallel and the distance between the two sections of the mounting channel steel is the length of the adjustment rail. Then, the adjustment rails at both ends are placed between the two sections of the mounting channel steel and are perpendicular to the mounting channel steel, so that the second driving gears at both ends of the adjustment rails are matched with the second driving racks; S2: Match the sliding grooves on both sides of the adjustable counterweight plate with the edges of the adjustable slide rail respectively, match the first driving gear on the adjustable counterweight plate with the first driving rack in the adjustable slide rail, connect the cantilever beam to the counterweight plate, and install the lifting rope on the cantilever beam; S3: Finally, start the first drive gear and the second drive gear, determine the best position of the cantilever installation according to the position of the lifting rope, move the adjusting counterweight plate to the best position, remove the cantilever beam, install the cantilever mechanism on the positioned adjusting counterweight plate, and connect the cantilever mechanism to the hanging basket.

[0024] By adopting the above solution, the best working position of the cantilever can be determined more easily, avoiding the need for repeated adjustments due to improper installation position of the cantilever mechanism.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The cantilever mechanism can adapt to different types of roofs and walls. When the cantilever mechanism is carried on the horizontal roof surface, the adjusting counterweight plate, the adjusting beam and the embedded counterweight plate are all in the same plane and fixed to the roof. The supporting beam is perpendicular to the embedded counterweight plate. Both sides of the embedded counterweight plate can be used to carry the counterweight block. The adjusting beam and the adjusting counterweight plate increase the fixing point and fixing area between the cantilever mechanism and the roof, which can make the cantilever mechanism more firmly fixed to the ground and effectively prevent the cantilever mechanism from being deflected by the influence of wind. When the cantilever mechanism is carried on the floor beam, the adjusting counterweight plate is bent. It is fixedly connected to the side and top surfaces of the floor beams of the upper layer, and the embedded counterweight plate is also bent and fixed to the bottom and sides of the floor beams of the lower layer. At this time, a stable triangular structure is formed between the support beam, the embedded counterweight plate and the adjustable counterweight plate, and the adjusting beam is fixed to the middle part of the support beam, thereby improving the bearing capacity of the support beam. When the cantilever mechanism is carried on the parapet, the adjustable counterweight plate is bent and fixed to the top and side surfaces of the parapet, and the embedded counterweight plate and the adjustable beam are fixed to the side surfaces of the parapet, and a stable triangular structure is still formed between the support beam, the embedded counterweight plate and the adjustable counterweight plate.

[0026] 2. When the cantilever mechanism is carried on a horizontal roof surface, it is necessary to frequently move the cantilever mechanism during its installation to move it to the best working position. Before fixing the cantilever mechanism, the mounting channel steel is first fixed to the ground through the mounting ears. The two mounting channel steels are parallel to the edge of the roof. The mounting channel steels are fixed to both ends of the adjusting slide rail. The second driving gear cooperates with the second driving rack. When the second gear is driven, the cantilever mechanism can be moved autonomously in the direction in which the mounting channel steel extends. By arranging a rack inside the adjusting slide rail, the first driving gear is started before the position of the cantilever mechanism is fixed. The cantilever mechanism can slide in the direction in which the adjusting track extends driven by the adjusting counterweight plate, so that it can be accurately adjusted to the best working position.

[0027] 3. Since the hanging basket realizes the change of up and down position through the lifting device, but the lifting device cannot accurately control the lifting height, and the frequent opening and closing of the lifting device is likely to cause the failure of the lifting device, thus causing safety hazards. By setting an auxiliary device on the hanging basket, the staff can adjust the height of the auxiliary pedal, and then fix the auxiliary pedal. The staff can stand on the auxiliary pedal to work, so that they can fine-tune their height, which has the effect of flexible operation. By setting the auxiliary frame, the auxiliary frame can be folded, and the staff on the working floor can place the tools in the tool bearing slot of the auxiliary frame, and then slide the tool bearing slot into the storage slot, which is convenient for the staff to take the tools from the working floor, reducing safety hazards. By setting a suction cup on the auxiliary pedal, when the hanging basket collides, the suction cup and the wall will play a buffering role, avoiding a strong collision between the hanging basket and the curtain wall, causing the hanging basket to smash the curtain wall. At the same time, in windy weather, the suction cup can absorb the curtain wall to prevent the hanging basket from swinging and causing safety hazards. The support rod can make the auxiliary device offset to the surface where the curtain wall is located, which not only prevents the entire hanging basket from hitting the curtain wall, but also increases the controllable distance of the suction cup to ensure that the suction cup can absorb the wall.

DETAILED DESCRIPTION

[0029] Therefore, it is necessary to provide a reverse-supported roof beam hanging basket 3 that can adapt to different building scenes.

[0030] A reverse-supported roof beam-riding hanging basket and a construction method thereof, comprising a plurality of cantilever mechanisms 1, a plurality of cantilever brackets 11 and a hanging basket 3.

[0031] Example 1 See also Figure 1-2 , Figure 1A schematic diagram of a reverse support type roof beam hanging basket structure provided in the first embodiment of the present application, the cantilever mechanism 1 is composed of a cantilever bracket 11, a cantilever beam 12, a counterweight rope 13, a hoisting rope 14 and a cantilever rope 15. The cantilever bracket 11 is vertically connected to the cantilever beam 12 to play a supporting role. The cantilever bracket 11 can be made of high-strength steel pipe or aluminum alloy profile, and the cantilever beam 12 can also be made of steel or light alloy material, and the counterweight rope 13 and the hoisting rope 14 are connected at both ends respectively. In addition, a cantilever rope 15 is additionally connected to both ends of the cantilever beam 12, and the cantilever rope 15 is kept in a tensioned state through the top of the cantilever bracket 11, thereby enhancing the stability of the system. The cantilever bracket 11 can be a telescopic rod structure, which can adjust the height and the tension of the cantilever rope 15. The cantilever beam 12 is also a telescopic structure, so as to better meet various usage requirements such as the horizontal roof surface 7 or the curved wall.

[0032] The adjusting device 2 includes a pre-embedded counterweight plate 21, an adjustable counterweight plate 22, an adjusting beam 23 and a supporting beam 24. The pre-embedded counterweight plate 21 and the adjustable counterweight plate 22 can be composed of two steel plates connected by a pivot. The two steel plates can be locked at any angle to better fit various usage scenarios such as a horizontal roof surface 7 or a curved wall. The support beam 24 includes a mounting sleeve 241 and a support inner rod 242. The mounting sleeve 241 can be made of alloy square steel. The side of the mounting sleeve 241 is linearly arranged with first mounting holes 2411 that can cooperate with the support inner rod 242 along the extension direction of the mounting sleeve 241. The mounting sleeve 241 is fixed to the two ends of the support inner rod 242 to form an adjustment beam 23 in an extended state. The support inner rod 242 is fixed to the mounting holes by bolts. The support inner rod 242 is connected to different mounting holes to enable the adjustment beam 23 to be unfolded to different lengths, thereby playing a role in fine-tuning the length. The support inner rod 242 can be a telescopic rod structure. After the support inner rod 242 can be extended to a certain length, the length can be fixed by means of bolts and limit holes, and the length can be adjusted. The middle part of the support inner rod 242 can be folded in half, and the folded support inner rod 242 can be stored in the mounting sleeve 241, so that the mounting sleeve 241 plays a storage role.

[0033] The structure of the adjusting beam 23 is similar to that of the supporting beam 24. The adjusting beam 23 includes a mounting channel steel 231 and an adjusting slide rail 232. The mounting channel steel 231 can be installed at both ends of the adjusting slide rail 232 to form the adjusting beam 23. The adjusting slide rail 232 includes two detachable sections. The joints of the two sections of the adjusting slide rail 232 can be connected together by inlaying and then fixed by bolts. The side of the mounting channel steel 231 is linearly arrayed along its length direction to form a second mounting hole 2311 that can cooperate with the supporting inner rod 242. The adjusting slide rail 232 can be fixed to the second mounting hole 2311 at different positions by bolts to fine-tune the length of the adjusting beam 23.

[0034] In this embodiment, the cantilever mechanism 1 is carried on the floor beam. At this time, the adjustable counterweight plate 22 is bent to cooperate with the side and top surface of the second floor beam 5. The second floor beam 5 is fixed to the adjustable counterweight plate 22 by bolts. The embedded counterweight plate 21 is also bent to cooperate with the bottom and side of the first floor beam 4 of the lower layer, and is also fixed with bolts. Since the embedded counterweight plate 21 and the adjustable counterweight plate 22 are fixed to the two surfaces of the floor beam, the floor beam will be subjected to shear force, so the embedded counterweight plate 21 and the adjustable counterweight plate 22 are more tightly connected to the floor beam. The support beam 24 is adjusted to a suitable length, and the cantilever beam 1 One end of the counterweight rope 13 is connected to the third mounting holes 121 distributed in a linear array along the length direction of the cantilever beam 12. After the support beam 24 is adjusted to a suitable length, one end is fixedly connected to the third mounting hole 121 by bolts, and the other end is hinged to the embedded counterweight plate 21. After the adjustment beam 23 is adjusted to a suitable length, one end is fixed to the adjustment counterweight plate 22 by bolts, and the other end is fixed to the middle of the support beam 24 by bolts. A stable triangular structure is formed between the support beam 24, the embedded counterweight plate 21 and the adjustment counterweight plate 22. The adjustment beam 23 can be fixed to the bending part of the support beam 24 to increase the stability of the support beam 24 structure.

[0035] One end of the counterweight rope 13 is fixed to the third mounting hole 121, and the other end is hinged to the embedded counterweight plate 21. The hoisting rope 14 is connected to the lifting device 33 inside the hanging basket 3. The lifting device 33 can be a lifting motor or a winch, or an electric hoist can be connected to the cantilever beam 12. When the lifting device 33 is started, the counterweight rope 13 bears the gravity of the hanging basket 3, thereby generating a pulling force on one end of the cantilever beam 12, and the other end of the cantilever beam 12 bears the pulling force provided by the support beam 24 and the counterweight rope 13. The pulling force provided by the counterweight rope 13 and the hoisting rope 14 at both ends of the cantilever beam 12 is downward. In order to prevent the cantilever beam 12 from bending, the tensioned cantilever rope 15 provides an upward pulling force to both ends of the cantilever beam 12, thereby preventing the cantilever beam 12 from bending, and the entire cantilever mechanism 1 is in a state of force balance.

[0037] A stable triangular structure is formed between the support beam 24, the embedded counterweight plate 21, the adjustment beam 23 and the adjustment counterweight plate 22. The adjustment beam 23 increases the fixing area of ​​the cantilever mechanism 1 and the parapet 6. At the same time, the adjustment beam 23 provides more fixing points to further enhance the tightness and stability of the connection between the cantilever mechanism 1 and the parapet 6.

[0039] When the cantilever mechanism 1 is supported on the horizontal roof surface 7, the mounting channel steel 231 is first fixed to the horizontal roof surface 7 through the mounting ear 2312, the two sections of the mounting channel steel 231 are arranged in parallel and the spacing between the two sections of the mounting channel steel 231 is the length of the adjusting slide rail 232, and then the adjusting slide rails 232 at both ends are placed between the two sections of the mounting channel steel 231 and perpendicular to the mounting channel steel 231, so that the second driving gear 2322 at both ends of the adjusting slide rail 232 cooperates with the second driving rack 2313, the sliding grooves 222 on both sides of the adjusting counterweight plate 22 are respectively cooperated with the edges of the adjusting slide rail 232, the first driving gear 221 on the adjusting counterweight plate 22 is cooperated with the first driving rack 2321 in the adjusting slide rail 232, the cantilever beam 12 is connected to the counterweight plate, and the lifting rope 14 is installed on the cantilever beam 12.

[0040] When the second gear is driven, the cantilever mechanism 1 can move autonomously in the direction in which the installation channel steel 231 extends. By setting a rack inside the adjustment slide rail 232, before the cantilever mechanism 1 is fixed, the first driving gear 221 is started, and the cantilever mechanism 1 can slide along the direction in which the adjustment track extends under the drive of the adjustment counterweight plate 22. After the adjustment counterweight plate 22 is moved to the best working position, the cantilever beam 12 is removed, and the cantilever mechanism 1 is installed on the positioned adjustment counterweight plate 22. Finally, the support beam 24 is adjusted to the most suitable length, and the support beam 24 and the cantilever beam 12 are vertically fixed at one end away from the lifting rope 14. The embedded counterweight plate 21 carries the support beam 24 and the counterweight block at the same time.

[0041] In this embodiment, by setting the first drive gear 221 and the first drive rack 2321 and the second drive gear 2322 and the second drive rack 2313, the cantilever mechanism 1 can be more flexibly adjusted in the installation position on the horizontal roof surface 7 to avoid frequent movement of the cantilever mechanism 1 due to improper installation position. After the cantilever mechanism 1 is installed, one end of the cantilever beam 12 is subject to the gravity of the hanging basket 3, and the counterweight block at the other end is carried on the embedded counterweight plate 21. The support beam 24 provides tension to the other end of the cantilever beam 12, so that the cantilever mechanism 1 is subjected to force balance.

[0042] Example 4 See also Figure 8-10 , Figure 8This is a schematic diagram of the structure of the hanging basket of the fourth embodiment of the present application. The structure of this embodiment is basically the same as the above embodiment, except that the hanging basket 3 also includes an auxiliary device 34 located outside the guardrail 32, including an auxiliary frame 341, and an auxiliary pedal 342 located in the auxiliary frame 341, the auxiliary pedal 342 protrudes from the inner wall surface of the guardrail 32, and stop racks 3411 are provided on the inner walls on both sides of the auxiliary frame 341, and stop blocks 3421 are provided on both sides of the auxiliary pedal 342, and the stop blocks 3421 can cooperate with the stop rack 3411. A stop assembly 343 is provided in the stop block 3421, and the stop assembly 343 includes a wedge-shaped pressing block 3431, a wedge-shaped sliding block 3432, a locking block 3433 and a second elastic member 3434. The wedge-shaped pressing block 3431 passes through the top of the stop block 3421, the wedge-shaped sliding block 3432 is located in the stop block 3421 and can cooperate with the wedge-shaped surface of the wedge-shaped pressing block 3431, the locking block 3433 is fixed to the side of the wedge-shaped sliding block 3432 away from the wedge-shaped pressing block 3431, the locking block 3433 can pass through the side of the stop block 3421 and cooperate with the stop rack 3411, and one end of the second elastic member 3434 is fixed to the inner wall surface of the stop block 3421, and the other end is fixed to the side of the wedge-shaped sliding block 3432 away from the locking block 3433.

[0043] Since the hanging basket 3 uses the lifting device 33 to achieve the change of the up and down position, but the lifting device 33 cannot accurately control the lifting height, and frequent opening and closing of the lifting device 33 is likely to cause the malfunction of the lifting device 33, thereby causing a safety hazard, by arranging an auxiliary device 34 on the hanging basket 3, the staff can adjust the height of the auxiliary pedal 342, and then fix the auxiliary pedal 342. The staff can stand on the auxiliary pedal 342 to work, so that they can fine-tune their own height, achieving the effect of flexible operation. Since both the wedge-shaped pressing block 3431 and the wedge-shaped sliding block 3432 are provided with wedge-shaped surfaces, and the wedge-shaped pressing block 3431 and the wedge-shaped sliding block 3432 cooperate with each other, after the staff slides the stop block 3421 to a suitable height, by pressing the wedge-shaped pressing block 3431, the wedge-shaped sliding block 3432 will drive the locking block 3433 to shift, and the locking block 3433 cooperates with the stop rack 3411 to achieve locking. When the staff needs to readjust the height, the wedge-shaped pressing block 3431 can be pulled up, and the second elastic member 3434 can pull the wedge-shaped sliding block 3432 to reset, and the locking block 3433 will be disengaged from the stop rack 3411, so as to avoid the staff from repeatedly disassembling and adjusting the height.

[0044] In this embodiment, a detachable support rod 346 is provided between the guardrail 32 and the auxiliary frame 341, and mounting columns are provided on both sides of the auxiliary frame 341, and the mounting columns are rotatable and the maximum rotation angle is 90°. The two ends of the support rod 346 can be rotatably connected to the side walls of the guardrail 32 and the auxiliary frame 341 respectively through the mounting columns, and the support rod 346 can be rotated to any angle for fixing, and a suction cup 3423 is provided on the side of the auxiliary pedal 342 away from the guardrail 32. The suction cup 3423 can be a rubber suction cup 3423, which has good elasticity and flexibility, and can be well fitted with curtain walls of various materials and surface shapes, and produce a strong adsorption force. Moreover, the rubber material itself has a certain buffering performance, and when the hanging basket 3 collides with the curtain wall, it can play a good buffering role and reduce the damage of the impact force to the curtain wall and the hanging basket 3.

[0045] The suction cup 3423 can also be a vacuum suction cup 3423. By extracting the air inside the suction cup 3423, a vacuum environment is formed, and a strong adsorption force is generated by atmospheric pressure. The vacuum suction cup 3423 can be controlled by a manual or electric vacuum pump to control adsorption and release. The vacuum pump can be set in the hanging basket 3, and the staff can manually adjust it. When the hanging basket 3 encounters strong winds, it will swing. During the swinging process, there is a risk of collision with the installed glass curtain wall. By setting the suction cup 3423 on the auxiliary pedal 342, when the hanging basket 3 collides, the suction cup 3423 and the wall surface will play a buffering role, avoiding a strong collision between the hanging basket 3 and the curtain wall, causing the hanging basket 3 to smash the curtain wall. At the same time, in strong winds, the suction cup 3423 can absorb the curtain wall to prevent the hanging basket 3 from swinging and causing safety hazards. The support rod 346 can make the auxiliary device 34 offset to the surface where the curtain wall is located, which not only prevents the entire hanging basket 3 from hitting the curtain wall, but also increases the controllable distance of the suction cup 3423 to ensure that the suction cup 3423 can absorb the wall surface.

[0046] Example 5 See also Figure 11-12 , Fig.1134 is a structural diagram of a hanging basket according to a fifth embodiment of the present application. The structure of this embodiment is basically the same as that of the above embodiments, except that, in this embodiment, the auxiliary device 34 is not equipped with a suction cup 3423 and a support rod 346, a rotating shaft 344 is passed through the middle of the auxiliary pedal 342, and the auxiliary pedal 342 can rotate around the rotating shaft 344, a stop surface 3441 is provided on the rotating shaft 344, a stop gear 345 is provided between the auxiliary pedal 342 and the stop block 3421, and a stop recess 3422 matching the stop gear 345 is provided on the side of the auxiliary pedal 342. The positioning block 3421 and the stop gear 345 can both cooperate with the stop surface 3441. The bottom plate 31 is provided with a storage groove 311, and sliding grooves 3111 are provided on both sides of the storage groove 311. The surface of the auxiliary frame 341 facing the guardrail 32 can be provided with a tool carrying groove for carrying tools, and a rotating shaft is passed through the bottom. A stop edge is provided on the edge of the bottom plate 31. When the rotation angle of the rotating shaft exceeds 90°, the stop edge can abut against the auxiliary frame 341. The auxiliary frame 341 can be flipped around the rotating axis to be perpendicular to the plane where the guardrail 32 is located, and then slide into the hanging basket 3 along the storage groove 311.

[0047] The working principle of this embodiment is as follows: when the staff needs other work tools during work, they need to lower the hanging basket 3 to the ground to pick them up. If the staff on the working floor hand them over during the construction process, it is an illegal operation and there is a safety hazard. Through the setting of the auxiliary frame 341, the auxiliary frame 341 can be folded, and the staff on the working floor can place the tools in the tool carrying slot of the auxiliary frame 341, and then slide the tool carrying slot into the storage slot 311, which is convenient for the staff to take the tools from the working floor and reduces safety hazards.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
