Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude construction tools, in particular to an operation device at the bottom of a large-span belt corridor. Background Technique

[0002] Generally, the belt corridor is made of steel, with a span of about 40 meters and a height of 20 meters from the bottom to the ground. There is no foothold for personnel to carry out anti-corrosion and rust-removing operations at the bottom. High-altitude operations are restricted by various on-site environments. When the on-site environment is open and vehicles can approach, a truck crane is used to lift personnel to the operation height for operation. Personnel are greatly restricted and need to have clear and good communication and command with the truck crane driver, which has relatively large uncertain factors and safety hazards. At the same time, the construction investment cost is huge. In places where the on-site environment is narrow and traffic is blocked and vehicles cannot approach, the method of erecting a scaffolding is used to carry out operations. In this way, the entire operation area needs to be scaffolded, which requires more labor and tools, increases the construction procedures, leads to an extended construction period, and wastes manpower and material resources. Content of the Utility Model

[0025] Please refer to Figures 1 to 6 , the present utility model provides a bottom operation device for a large-span belt corridor, which is connected to the truss 1 at the bottom of the belt corridor. The device includes a suspended basket 2 for carrying operators and two first steel wire ropes 3 connected to the truss 1. The two first steel wire ropes 3 are detachably connected to the truss 1. The distance between the two first steel wire ropes 3 matches the length of the suspended basket 2. A pulley 4 is provided at the top of the suspended basket 2, and the suspended basket 2 is hung on the first steel wire rope 3 through the pulley 4. By horizontally erecting and suspending the suspended basket 2 with the first steel wire rope 3, the construction defect that the high-altitude operators at the bottom of the existing belt corridor have no foothold is solved. In this way, it is not restricted by the on-site environment, reduces the input of labor and equipment costs, shortens the construction period, and improves the comfort and safety of personnel operations. The length, width and height of the suspended basket 2 are: 2750mm * 720mm * 1280mm.

[0026] Specifically, a second steel wire rope 5 for hanging a safety belt is further arranged between two first steel wire ropes 3, and the second steel wire rope 5 is detachably connected to the truss 1. The diameters of the first steel wire rope 3 and the second steel wire rope 5 are both 14 mm.

[0027] Specifically, both the first steel wire rope 3 and the second steel wire rope 5 are fixed to the truss 1 through wire rope clips 6. The wire rope clips 6 can be directly purchased on the market and belong to the prior art.

[0028] Specifically, wire rope corner guards 7 for protecting the first steel wire rope 3 and the second steel wire rope 5 are arranged at the corners of the truss 1. The truss 1 is composed of I-beams or H-beams. Through the wire rope corner guards 7, it can be prevented that the first steel wire rope 3 and the second steel wire rope 5 directly contact the flange of the truss 1, effectively preventing the damage to the steel wire rope caused by the acute angle cutting of the flange. The wire rope corner guards 7 can be directly purchased on the market and belong to the prior art.

[0029] Specifically, the hanging basket 2 is composed of two first side plates 21 arranged along the length direction of the hanging basket 2, two second side plates 22 arranged along the width direction of the hanging basket 2, and a scaffolding bottom plate 23 arranged at the bottom of the first side plates 21 and the second side plates 22. The first side plates 21 and the second side plates 22 form a square structure. A connecting member 8 is fixedly arranged at the top of the first side plate 21. The connecting member 8 is connected with a U-shaped shackle 9. Each connecting member 8 has a through hole, and the lower end of the U-shaped shackle 9 is inserted into the through hole. The pulley 4 is connected to the upper end of the U-shaped shackle 9. The first side plates 21 and the second side plates 22 are of a detachable connection structure, and the scaffolding bottom plate 23 is also detachably connected to the first side plates 21 and the second side plates 22. In the present utility model, the hanging basket 2 adopts an assembled structure, which is convenient for transportation.

[0030] Specifically, the first side plate 21 is composed of a first bottom rod 211 arranged along the length direction of the hanging basket 2, three first vertical rods 212 arranged along the height direction of the hanging basket 2, and a first top rod 213 arranged along the length direction of the hanging basket 2. The two ends of each first vertical rod 212 are respectively connected to the first bottom rod 211 and the first top rod 213, and the three first vertical rods 212 are evenly distributed between the first bottom rod 211 and the first top rod 213. A first metal mesh assembly 214 is arranged between adjacent first vertical rods 212; the first bottom rod 211, the first vertical rods 212 and the first top rod 213 form a frame structure, and by installing the first metal mesh assembly 214, while protecting the operators, the weight of the hanging basket 2 can also be reduced.

[0031] The second side plate 22 includes two cross bars 221 and a second wire mesh assembly 222. The second wire mesh assembly 222 is disposed between the two cross bars 221. Connection pieces 223 are respectively fixedly connected to the end portions of each cross bar 221. Connection holes are formed in the connection pieces 223. One end of a first bolt passes through the connection holes and the first side plate 21 and is then connected to a nut. Similar to the first side plate 21, the second side plate 22 composed of two cross bars 221 and the second wire mesh assembly 222 can, while protecting the operators, also reduce the weight of the hanging basket 2.

[0032] The first bottom bar 211, the first vertical bar 212, the first top bar 213, and the cross bar 221 are all made of hollow square tubes with a model of 30*30. Square tubes of this model specification can be directly purchased on the market.

[0033] Specifically, the hanging basket 2 further includes three connecting rods 24. All three connecting rods 24 are connected to the first bottom bar 211. The three connecting rods 24 are evenly distributed at the bottom of the hanging basket 2. The scaffold floor 23 is detachably connected to the tops of the connecting rods 24. Three holes for avoiding the connecting rods 24 are formed in the first wire mesh assembly 214. When installing the connecting rods 24, the connecting rods 24 are installed on the first bottom bar 211 from top to bottom.

[0034] Specifically, two short bars 25 are respectively connected to the two end portions of each connecting rod 24. A clamping groove 26 is formed between the two short bars 25 on the same side of the connecting rod 24. The first bottom bar 211 is located in the clamping groove 26, and a second bolt 27 is connected to the lower end of the short bar 25. When installing the connecting rod 24, the connecting rod 24 moves from top to bottom, so that the first bottom bar 211 is accommodated in the clamping groove 26. Subsequently, by tightening the second bolt 27, the first bottom bar 211 is fixed in the clamping groove 26, realizing the fixation of the first bottom bar 211 and the connecting rod 24. When disassembling, by unscrewing the second bolt 27 and moving the connecting rod 24 upward, the connecting rod 24 can be separated from the first bottom bar 211.

[0035] Specifically, two pin cable tensioners 10 are further connected to each first steel wire rope 3. The pin cable tensioners 10 are disposed on the side of the pulley 4 close to the truss 1. The pin cable tensioners 10 prevent the hanging basket from moving freely on the first steel wire rope and play a role in fixing the position of the hanging basket on the first steel wire rope.
