Description

Technical Field

[0001] The invention relates to the technical field of outdoor construction, and in particular to a slidable aerial work operation platform. Background Art

[0002] The hanging basket is a construction tool for high-altitude operations in construction projects, used for curtain wall installation and exterior wall cleaning. The hanging basket is a new type of high-altitude operation equipment that can replace traditional scaffolding, reduce labor intensity, improve work efficiency, and can be reused. However, the traditional hanging basket can only be used for vertical facades without special shapes. However, with the development of the construction industry, the aesthetics of architectural forms are also developing rapidly. Designers usually integrate their own design concepts into the building, thus forming a variety of architectural shapes. The traditional hanging basket can no longer meet the construction needs.

[0003] In some special-shaped structures, for example, the 1st to 11th floors of a building are divided into two single buildings, and the 12th to roof floors are formed into a whole by a steel structure. The maximum span of the connected part is 26 meters. The steel structure connected part is constructed by an integral hydraulic lifting technology. After the connected part is installed in place, its bottom is more than 50 meters from the ground. The conventional curtain wall construction hanging basket cannot meet the installation requirements of the aluminum plate ceiling of the curtain wall at the bottom of the connected part. The height difference between the ground and the bottom of the connected part is large. There are many disadvantages in setting up a full-hall operating frame on the ground, namely, the cost of setting up is high, and the ground load exceeds the design bearing capacity of the floor slab. Due to the high height, it is impossible to use spider cars and other climbing equipment for construction. The site is narrow and the wind load is large. The construction safety cannot be guaranteed and the full coverage of the construction surface cannot be achieved. Taking various factors into consideration, an innovative "sliding aerial work operation platform" is used for construction to realize the sliding of the hanging basket at the bottom of the connected part. However, if a hard rail, such as a steel rail, is used, the rail needs to be installed on the upper part of the aluminum plate, and it is difficult to remove the rail and close the aluminum plate curtain wall in the later stage. Therefore, choosing a soft rail hanging basket can effectively solve this problem. That is, the sliding aerial ropeway hanging basket can be used as the operating platform for the construction of the connected bottom aluminum plate curtain wall. Summary of the invention

[0030] Example 1

[0031] like Figure 1 to Figure 6 As shown, the present invention provides a technical solution:

[0032] A slidable aerial work operating platform, which at least includes but is not limited to a main frame 1, a lifting rope 2, a pulling rope 3 and a hanging basket 4; the lifting rope 2 is retractably fixed to the lower position of the main frame 1 through a bracket, the hanging basket 4 is connected to the lifting rope 2, the pulling rope 3 is set at a position matching the hanging basket 4, the pulling rope 3 is connected to the main frame 1, and a lifting mechanism is set on the hanging basket 4, so that the hanging basket 4 can move up and down along the hanging point.

[0033] Based on the above structure, in a special-shaped structure, when construction is required on the top building, the main frame 1 is fixed in the specified area, and then the construction workers pull the pulling rope 3 to adjust the horizontal position of the hanging basket 4, and then adjust the vertical height of the hanging basket 4 through the lifting mechanism, finally realizing the height adjustment of the position of the hanging basket 4 in the special-shaped structure.

[0034] As an example, the main frame 1 may include a top connecting frame 11, a support column 12 and a bottom connecting frame 13, the support column 12 is vertically arranged between the top connecting frame 11 and the bottom connecting frame 13, and a plurality of support columns 12 are provided, and the bottom connecting frame 13 is provided with a hanging rope 14 for auxiliary support of the lifting rope 2, and a plurality of hanging ropes 14 are evenly arranged along the length direction of the bottom support frame.

[0035] Based on the above structure, during installation, the top connecting frame 11 is connected to the top surface of the building to fix the entire platform, and the top connecting frame 11 and the bottom connecting frame 13 are connected into a stable whole through multiple support columns 12 to provide support for the movement and lifting of the hanging basket 4 and ensure the safety of the operators.

[0036] As an example, the two ends of the bottom support frame are symmetrically provided with steering support frames 15, and the steering support frames 15 are connected to the I-beams at the ends of the bottom support frame;

[0037] The steering support frame 15 may include a transverse support rod 151, a vertical support rod 152 and an oblique support rod 153; the transverse support rod 151 is vertically arranged with the vertical support rod 152, a plurality of transverse support rods 151 are arranged in parallel, the oblique support rod 153 is arranged between the I-beam and the vertical support rod 152, a first fixed pulley 154 is arranged at the end of the uppermost transverse support rod 151; a second fixed pulley 155 is arranged at the bottom of the vertical support rod 152;

[0038] Based on the above structure, the steering support frame 15 is used to guide and support the lifting rope 2. One end of the lifting rope 2 is fixed on the support column 12, and passes through the first fixed pulley 154 and the second fixed pulley 155 and then connects to the steering support frame 15 at the other end. Through two second fixed pulleys 155 at the same horizontal height, the entire lifting rope 2 is kept tensioned. The first fixed pulley 154 and the second fixed pulley 155 are provided to facilitate the adjustment of the lifting rope 2.

[0039] As an example, a first fixing portion 111 and a second fixing portion 112 are provided on the top connection frame, a safety rope 113 may be provided on the first fixing portion 111, and an end of the safety rope 113 is connected to the hoisting rope 2, and a tensioner 114 may be provided on the second fixing portion 112; ends of the tensioner 114 are respectively connected to ends of the safety rope 113 and ends of the hoisting rope 2;

[0040] The tensioner 114 may specifically be a hand chain hoist or an electric hoist;

[0041] Based on the above structure, the safety of the hoisting rope 2 can be ensured by the safety rope 113, and the tension of the entire hoisting rope 2 can be adjusted by setting the tensioner 114.

[0042] As an example, a first limiting plate 131 and a second limiting plate 132 are provided at the bottom position of the bottom connecting frame. The first limiting plate 131 and the second limiting plate 132 are symmetrically arranged. Limiting through holes for the lifting rope 2 to pass through are provided on the first limiting plate 131 and the second limiting plate 132. The lifting rope 2 is arranged to pass through the limiting through holes.

[0043] Based on the above structure, since the hoisting rope 2 will shake to a certain extent when coming out from the second fixed pulley 155, passing the hoisting rope 2 through the limiting through hole can further limit the position of the hoisting rope 2 and ensure that the hoisting rope 2 always moves at the specified position.

[0044] As an example, the hanging basket 4 may include a basket structure 41, a connecting rope 42, a shackle pulley 43 and a lifting structure; the basket structure 41 is connected to the shackle pulley 43 through the connecting rope 42, and the shackle pulley 43 is placed on the lifting rope 2; the lifting mechanism is arranged on the basket structure 41, and a travel limit block 44 is arranged on the end of the connecting rope 42 close to the shackle pulley 43; a plurality of rope clamps are arranged on the travel limit block 44, and a distance sensor 45 may also be arranged on the basket structure 41;

[0045] Based on the above structure, when the hanging basket 4 runs vertically, when the limit block presses down the travel switch contact, the electric bell alarms and the rising circuit is cut off. In addition, a distance measuring sensor 45 is installed at the limit block and the truss position of the hanging basket 4. When the distance is less than 0.5 meters, the distance will be announced by voice. The lifting mechanism is a conventional structure of the hanging basket 4, and this application has not made any improvements to it, so it will not be repeated.

[0046] As an example, two hanging ropes 14 can be provided at the same position. The two hanging ropes 14 can ensure that the support of the hanging ropes 14 is more stable on the one hand, and can improve the safety of the hanging basket 4 crossing the hanging ropes 14 on the other hand.

[0047] Based on the above structure, when the hanging basket 4 moves horizontally, it will need to cross multiple hanging ropes 14. The specific process is that when it is necessary to cross the position of the hanging rope 14, firstly connect the two ends of the auxiliary tool hand winch or wrench winch to the bottom connection frame and the predetermined position for support after crossing the hanging rope 14, so that the hanging basket 4 is located between the two hanging points. At this time, the hook at the location of the hanging rope 14 can be released. At this time, the force will be supported by the auxiliary tool, and then the hanging basket 4 is manually pulled horizontally to cross the hanging point, and after hanging the hanging rope 14, the auxiliary tool is released to complete the crossing of the hanging point.

[0048] The aerial work operation platforms of this scheme are usually used in combination. In the area to be installed, the predetermined aerial work operation platforms are arranged in parallel in the same direction. When assembled and used, a specified safety distance is reserved between adjacent aerial work operation platforms.

[0049] As an example, the steering support frame is welded with 80*80*5 galvanized steel pipes, the horizontal triangular support is welded with 50*50*5 angle steel, and each bracket end is welded with 2 sets of finished national standard pulleys. The qualified conversion bracket is welded to the steel beams on both sides of the steel structure joint, and the weld is a third-level weld;

[0050] The hoisting rope 2 is made of galvanized steel wire rope with a diameter of 16mm, specification 6*37+FC, breaking tension of steel wire rope 12.6T, safe load bearing 2.2T. The two ends of the hoisting rope 2 are respectively passed through the pulleys of the cableway conversion brackets on both sides and turned into the steel structure joint upper structure. One end of the cableway is fixed to the steel column by a buckle lock, and the main rope at one end is connected to the 5T manual hoist, and the auxiliary rope is connected to the 16# channel steel welded on the upper I-beam by a buckle lock.

[0051] As an example, the thickness of the first limit plate 131 and the second limit plate 132 is 3mm, the size is 200mm*200mm, and they are fixed at a distance of 300mm from the two end force steering support frames. The cableway basket 4 structure also includes: a cableway anti-snag device, including a wire rope and a shackle; wherein the φ8 wire rope is fixed on the bottom steel beam of the steel structure joint body around the beam, one end of the shackle is locked with the φ8 wire rope through a buckle, and the other end is connected to the cableway wire rope through the shackle, and an anti-disturbance device is set every no more than 10m.

[0052] As an example, the basket structure 41 uses three 2.0m standard sections to assemble a 6m standard ZLP-630 hanging basket 4. The working surface of the hanging basket 4 is located at the top of the hanging basket 4, and the operating platform of the hanging basket 4 is located at the middle truss position of the guardrail. The operating platform is composed of L50x5 angle irons and templates. The angle irons are welded to the trusses on both sides of the hanging basket 4, and the templates are connected to the angle irons by bolts, and the operating platform of each hanging basket 4 independently tensions a safety steel wire rope with a diameter of 8mm along the span direction.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
