A small or medium-sized cylindrical silo needs to be equipped with 12 to 16 hanging baskets. When encountering a large silo cluster, a corresponding number of hanging baskets are required to meet the construction needs. The increase in the number of hanging baskets will greatly increase the workload of the hanging basket transfer, which will affect the construction progress, increase the labor force, and waste resources.

By using a pulley block instead of a suspension mechanism, the wear between the wire rope and the concrete surface can be avoided, and the service life of the wire rope can be increased. The pulley block can be used in various construction scenes with overhanging eaves, greatly enhancing the practicality. This device is easy to install and has reliable performance. The characteristics of the pulley block allow the motor to rise the suspension equipment without full load, which reduces the motor loss rate and increases the service life. For buildings with overhanging eaves, the pulley block can reduce the distance between the suspension equipment and the exterior wall, so that the operator can get an optimal working distance and improve work efficiency.

[0015] 2. The structural ring beam is fixed to the inner ring of the original truncated cone-shaped silo roof through a special steel ring.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, but the embodiments should not be construed as limiting the present invention.

[0019] In view of the technical problems involved in the background technology, the measures to solve the difficulties in exterior wall operations and the large amount of installation come from the adjustment of the construction method.

[0020] For traditional installation processes, we should consider changing the installation method and minimize unnecessary steps to improve construction efficiency.

[0021] Example 1 Embodiment 1 of the present invention includes the following parts: See also Figures 1 to 3 The shallow silo outer wall operation hanging basket mechanism of the present invention comprises a shallow silo composed of a cylindrical barn 1 and a frustoconical silo roof 2, wherein the cylindrical barn 1 is evenly distributed with a plurality of suspension devices 4 suspended by steel wire ropes 3 along the circumferential direction, and a plurality of pulley block fixing devices 5 are evenly fixed with the top of the gutter outer wall of the cylindrical barn 1 along the circumferential direction, and a vertically arranged first fixed pulley 6 is arranged at the top of each pulley block fixing device 5, and a second fixed pulley 7 is arranged radially along the gutter outer wall of the cylindrical barn 1 on the outer side surface of the pulley block fixing device 5, and each first fixed pulley 6 and the corresponding second fixed pulley 7 constitute a pulley block, and each steel wire rope 3 passes through a pulley block and is connected to the corresponding suspension device 4.

[0022] See also Figure 4Each pulley block fixing device 5 is composed of an inverted "U"-shaped clamp 51 with an opening downward and a stop plate 52 connected to the bottom of one end of the inverted "U"-shaped clamp 51. The stop plate 52 is located at one end of the inverted "U"-shaped clamp 51 close to the center of the truncated cone-shaped silo roof 2 and extends to the other end of the inverted "U"-shaped clamp 51. A notch is provided between the stop plate 52 and the other end. The top of the gutter outer wall of the cylindrical barn 1 is an inverted "L"-shaped structure. The inverted "U"-shaped clamp 51 is in contact with the top of the gutter outer wall on three sides. The stop plate 52 is against the bottom surface of the horizontal section of the top of the gutter outer wall of the cylindrical barn 1. In one or more embodiments, the stop plate 52 is provided with an expansion bolt 53 connected to the bottom surface of the horizontal section of the top of the gutter outer wall of the cylindrical barn 1.

[0023] The large distance between the hanging basket working platform and the outer wall makes it difficult for workers to work. The friction between the wire rope 3 and the contact surface of the cantilevered eaves structure causes great wear of the wire rope 3, which will affect the personal safety of the construction workers. The pulley block and the pulley block fixing device 5 are used as a fulcrum to shorten the distance between the hanging basket hanging equipment 4 and the outer wall of the gutter. The characteristics of the pulley block can make the motor no longer run at full load during the rising process. The setting of the pulley block can avoid direct wear between the wire rope 3 and the structure, greatly improving the construction efficiency while ensuring safety.

[0024] Example 2 Based on Example 1, the embodiment of the present invention also includes the following parts: See also Figures 5 to 9 The top inner ring of the truncated cone-shaped silo roof 2 is provided with an inner ring 8 arranged along the circumference of the inner ring. In one or more embodiments, see Figure 7 The inner ring 8 is a 10# channel steel ring with an opening facing outward; the inner ring 8 is connected to the top inner ring of the truncated cone-shaped silo top 2 by a plurality of long hexagonal bolts 9 evenly distributed along the circumferential direction. In a further embodiment, see Figure 8 The inner ring 8 is composed of two sections of 10# channel steel arcs, and the two sections of 10# channel steel arcs are connected at the joints by a connecting plate 12 and bolts; see Fig. 9 The outer side of the inner ring 8 is evenly distributed with a plurality of steel bars 7 arranged radially, and the outward ends of the plurality of steel bars 7 are provided with an outer ring 6 coaxially arranged with the inner ring 8. In one or more embodiments, the outer ring 6 is a φ20mm round steel with a circular cross-section.

[0025] See also Fig.10 One end of the steel wire rope 3 is provided with a rope buckle 31 for passing the outer ring 6. The steel wire rope 3 is provided with a raised observation port 32 at the short end of the rope buckle 31, and the observation port 32 is located between the rope buckle 31 and the end.

[0026] In view of the large number of hanging baskets installed, the large transfer volume and the high labor consumption, steel rings can be used to replace the configuration blocks and suspension mechanisms mentioned in the background technology. The flexibility of the steel rings can be used to connect the steel wire rope 3 used in the hanging basket operation with the outer ring 6 of the steel ring as a fixed point for the hanging basket equipment. Not only the suspension mechanism and counterweight block in the prior art are eliminated, but also when the hanging basket transfers the working surface, the round steel characteristics of the outer ring can be used to directly move the rope buckle 31 of the steel wire rope 3 on the outer ring 6, which can move synchronously with the hanging equipment 4, thereby improving the efficiency of the hanging basket transfer process.

[0027] Example 3 Based on Example 2, the embodiment of the present invention also includes the following parts: See also Fig.11 A plurality of short concrete columns 10 are evenly distributed along the circumferential direction on the upper slope of the truncated cone-shaped warehouse roof 2. All the short concrete columns 10 are connected by a safety rope 11. The safety rope 11 is tied with a steel wire rope 3 for ensuring the safety of construction workers.

[0028] See also Fig.12 A pulley block fixing device 5 is fixed on the top of the corresponding gutter outer wall between adjacent concrete short columns 10, and a vertically arranged first fixed pulley 6 is provided on the top of the pulley block fixing device 5. The outer side surface of the pulley block fixing device 5 is provided with a second fixed pulley 7 radially arranged along the gutter outer wall of the cylindrical barn 1. Each first fixed pulley 6 and the corresponding second fixed pulley 7 constitute a pulley block.

[0029] Example 4 On the basis of embodiments 1 to 3, the embodiments of the present invention further include the following parts: See also Fig.13 The method for installing a hanging basket for working on the outer wall of a shallow silo of the present invention comprises the following steps: S1. Installation of cantilever equipment 4 The hanging basket equipment is transported to the designated construction area, and the ground is cleaned to facilitate the placement of equipment parts. After the suspension equipment 4 is assembled, the motor, electric box, and safety lock are installed. After the assembly is completed, the suspension equipment 4 is evenly placed around the cylindrical barn 1.

[0030] S2. Installation of steel ring The 10# channel steel customized by the manufacturer (after sufficient demonstration, the steel plate has good rigidity and strong toughness) is used as the inner ring 8, and the φ20mm round steel is used to form the outer ring 6. The outer ring 6 and the inner ring 8 are welded with φ28 steel bars 7 to form a steel ring. The steel ring is divided into two sections as a whole. Bolt holes are processed at the joints of the two sections of the inner ring 8 and hoisted to the designated area. The two sections are spliced ​​together using hoisting equipment. After the ends are spliced, the two sections of 10# channel steel are connected through the bolt holes using connecting plates 12 and bolts. The connection of the inner ring 8 can be freely adjusted in size and fixed according to the top inner ring beam of the frustum-shaped silo roof 2. Tighten the 14 long hexagonal bolts 9 evenly distributed along the top inner ring of the frustum-shaped silo roof 2 to fix the steel ring, and weld the two sections of φ20mm round steel into the outer ring 6.

[0031] S3, installation of wire rope 3 Pass one end of the steel wire rope 3 at both ends of each suspension device 4 through the outer ring 6 to form a rope buckle 31 and fix it, so that the steel wire rope 3 is fixed on the outer ring 6. The rope clamps 13 should be clamped in sequence starting from the lifting point, and between the last rope clamp 13 and the previous rope 13 at the short end of the rope buckle 31, the steel wire rope 3 is slightly arched to form an observation port 32 as a safety device for observing whether the steel wire rope 3 is loose.

[0032] S4. Pulley installation The pulley block fixture 5 is set at the position where the top of the gutter outer wall of the cylindrical barn 1 contacts the wire rope 3. The inverted "U"-shaped clamp 51 of the pulley block fixture 5 is clamped on the top of the gutter outer wall. The inverted "U"-shaped clamp 51 and the stop plate 52 are welded to form the pulley block fixture 5. The double expansion bolts 53 of the stop plate 52 at the bottom of the pulley block fixture 5 are tightened to make the stop plate 52 press against the top of the gutter outer wall to prevent displacement. The wire rope 33 passes through the pulley block device to prevent the wire rope from contacting, wearing and displacing with the wall. The wire rope 3 is connected to the hoist of the suspension device 4. At this point, the hanging basket equipment is installed.

[0033] S5. Install safety rope 11 A 10 mm safety rope 11 made of steel wire is fixed around the concrete short column 10 on the slope of the truncated cone-shaped warehouse roof 2 to form a circle of safety rope 11. The steel wire rope 3 on the construction workers is put on this circle of safety rope 11. The construction workers can move laterally within a certain range, making the construction more flexible.

[0034] S6. Inspection and debugging After the above installation is completed, check whether the soft material part of the steel wire rope 3 in contact with the concrete has slipped out, focus on checking the fastening state of the buckle at each connection, connect the power supply and check whether the two motors work synchronously, and whether the safety lock can work normally in an emergency.

This is fixed on the inner ring ring beam at the top of the truncated cone-shaped warehouse roof 2 by a steel ring. The steel ring can be adjusted according to the bolts at the connection to adapt to the inner ring structure ring beam, and the wire rope 3 of the hanging basket operation is connected to the outer ring 6 of the steel ring, which can flexibly follow the suspension device 4 to move along the working surface. Moreover, the pulley block and the pulley block fixing device 5 can be used as the fulcrum of the hanging basket suspension platform.
