Description

Technical Field

[0001] The present invention relates to an emergency rescue jib for buried people in a grain pile, and more particularly to an emergency rescue jib for buried people in a grain pile that is easy to disassemble and assemble. Background Art

[0002] When discharging grain from a granary, due to the long storage time of the grain, wall hanging and capping phenomena will occur. At this time, operators need to go to the vicinity of the grain with wall hanging and capping, and use tools to open the capping. When the wall hanging and capping phenomena are eliminated, the rapid surging of the grain pile will cause a phenomenon similar to quicksand, and then accidents of people being buried by the grain pile will occur.

[0003] To avoid the occurrence of accidents of people being buried by the grain pile, the traditional method is to tie a safety rope to the operator and pass the safety rope through the expansion bolt hanging ring installed on the wall in advance, and another person pulls the safety rope to lift the operator when the grain pile surges rapidly. Since this operation must be carried out by two people at the same time, it is time-consuming and laborious. Using a remote-controlled rope climber can save manpower and has greater strength, and can play a better role in emergency rescue when an accident of people being buried by the grain pile occurs. However, the remote-controlled rope climber can only be installed on the ground or the roof when in use, and the operation is inconvenient when the roof is too high. Therefore, a jib needs to be installed on the wall in advance when using the remote-controlled rope climber. However, large granaries have a large area and multiple jibs need to be installed, resulting in high costs. There is an urgent need for an emergency rescue jib for buried people in a grain pile that is easy to disassemble and assemble in order to achieve the emergency rescue effect and save construction costs. Summary of the Invention

[0004] An emergency rescue jib for buried people in a grain pile that is easy to disassemble and assemble, which does not need to install multiple jibs on the wall and can be reused.

[0005] The present invention provides an emergency rescue jib for buried people in a grain pile that is easy to disassemble and assemble, including a ratchet winch, a steel wire rope, a main jib, and nylon foot cups. The main jib is a square tube structure, and a fixing surface center hole is provided at the center of the fixing surface of the ratchet winch and coincides with the pipe orifice of the main jib; the steel wire rope is a double-loop steel wire rope at both ends, and the steel wire rope passes through the inside of the main jib and is movably connected to the roller of the ratchet winch; a rope climber hanging ring is provided at the end of the main jib close to the ratchet winch; the first section of the column and the second section of the column are in a straight line and there is a gap at the joint, and the column connecting rod is welded on both sides of the joint of the first section of the column and the second section of the column. The end of the main jib away from the ratchet winch forms a T shape with the welded first section of the column and the second section of the column, and the main jib is completely penetrated at the top of the T shape; the upper bracket of the main jib forms a triangular structure with the main jib and the second section of the column, and the lower bracket of the main jib forms a triangular structure with the main jib and the first section of the column; a lower bracket is provided at the end of the first section of the column, and the lower bracket forms a T shape with the first section of the column in a plane perpendicular to the main jib; nylon foot cups are installed at both ends of the lower bracket and the top of the second section of the column.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] As shown in the figure, the present invention discloses an easily disassembled and assembled emergency rescue boom for buried people in grain piles, including a ratchet tightener 1, a steel wire rope 12, a main boom 3, and a nylon foot cup 6. It is characterized in that the main boom 3 is a square tube structure, and this square tube structure allows the steel wire rope to pass through the inside.

[0017] The center of the fixing surface of the ratchet tightener 1 is provided with a fixing surface center hole 16 which coincides with the nozzle of the main boom 3. The ratchet tightener bracket 15 is of a U-shaped structure. The bottom of the U-shaped structure is the fixing surface, and a fixing surface center hole 16 with a size equivalent to that of the nozzle of the main boom 3 is machined at the center of the fixing surface. The two arms of the U-shaped structure are perforated and penetrated by the ratchet tightener roller 19. A ratchet 17 is arranged on one side of the ratchet tightener roller 19, and the reverse rotation of the ratchet 17 is restricted by a movable ratchet pawl 18.

[0018] The steel wire rope 12 is a double-loop steel wire rope at both ends. The double-loop steel wire rope at both ends is a steel wire rope with pressed loops at both ends, that is, after being bent on both sides of the steel wire rope, it is tightly pressed with an aluminum sleeve. The steel wire rope 12 passes through the inside of the main boom 3 and is movably connected to the ratchet tightener roller 19. A roller column 20 is arranged on the ratchet tightener roller 19. This roller column 20 rotates following the ratchet tightener roller 19, and the steel wire rope 12 passing through the inside of the main boom 3 is hung on this roller column 20, and the steel wire rope 12 is tightened as the ratchet tightener roller 19 rotates.

[0019] A climbing rope machine lifting ring 11 is arranged at the end of the main boom 3 close to the ratchet tightener 1 for hanging the climbing rope machine.

[0020] The first section 8 of the column and the second section 9 of the column are in a straight line and there is a gap at the joint. The column connecting rod 10 is composed of two square tubes of the same length. The column connecting rod 10 is welded on both sides of the joint of the first section 8 and the second section 9 of the column. The end of the main boom 3 far from the ratchet tightener 1 forms a T-shaped structure with the welded first section 8 and the second section 9 of the column. The first section 8 and the second section 9 of the column are in a straight line and there is a gap at the butt joint, and this gap can pass through the main boom 3.

[0021] The main boom 3 is completely penetrated at the top of the T-shaped structure. The welded first section 8, the second section 9, and the column connecting rod 10 of the column can be understood as the horizontal part at the top of the T-shaped structure. The main boom 3 is of a tubular structure. The main boom passes through the gap reserved by the welded first section 8, the second section 9, and the column connecting rod 10, and ensures that the main boom 3 is completely penetrated, that is, both ends of the square tube of the main boom 3 are completely unobstructed, and the steel wire rope 12 is passed through the inside of the main boom 3.

[0022] The upper bracket 5 of the main boom forms a triangular structure with the main boom 3 and the second section 9 of the column; the lower bracket 4 of the main boom forms a triangular structure with the main boom 3 and the first section 8 of the column; the upper bracket 5 and the lower bracket 4 of the main boom are of a tubular structure.

[0023] A lower bracket 7 is arranged at the end of the first section 8 of the column. The end of the first section 8 of the column is far from the butt joint of the first section 8 and the second section 9. The lower bracket 7 forms a T-shaped structure with the first section 8 of the column in a plane perpendicular to the main boom 3.

[0024] Nylon foot cups 6 are installed at both ends of the lower bracket 7 and the top of the second section 9 of the column. The top of the second section 9 of the column is the part of the second section 9 of the column that is far from the butt joint of the first section 8 and the second section 9 of the column.

[0025] Before using this example, expansion screw hangers 14 need to be installed on the wall in advance. During installation, the first end of the steel wire rope 12 is movably connected to the expansion screw hanger 14 with a U-shaped hanger 13, and the second end of the steel wire rope 12 is movably connected to the roller column 20 of the ratchet tightener. A ratchet tightener force arm 2 perpendicular to the roller 19 of the ratchet tightener is provided at the end of the ratchet tightener 1 away from the ratchet 17. Rotating the ratchet tightener force arm 2 causes the roller 19 of the ratchet tightener to rotate and tighten the steel wire rope. During disassembly, separate the pawl 18 from the ratchet 17, rotate the roller 19 of the ratchet tightener in the reverse direction to release the steel wire rope, and disassemble the U-shaped hanger 13.

[0026] The nylon foot cup 6 is closely attached to the wall after the steel wire rope is tightened, playing an anti-slip role. The nylon foot cup 6 is fixed with its own screw. When the U-shaped hanger 13 is relatively large, the height of the nylon foot cup 6 is increased by adding a gasket, so as to adjust the distance between this example and the wall to prevent the U-shaped hanger 13 from getting stuck at the end of the main boom 3.

[0027] Furthermore, the side of the main boom 3 away from the ratchet tightener 1 is an open structure; the gap at the butt joint of the first section 8 and the second section 9 of the column is slightly larger than the height of the main boom 3. In this example, the square tube used for the main boom 3 is a square square tube, so the width and height of the main boom 3 are the same. The back of the open side of the main boom 3 is closely attached to the second section 9 of the column. The open side of the end of the main boom 3 away from the ratchet tightener 1 faces the first section 8 of the column, and the back of the open side of the main boom 3 is closely attached to and perpendicularly welded to the second section 9 of the column.

[0028] The main boom 3 is a square tube structure. The side of the main boom 3 away from the ratchet tightener 1 is an open structure. The first section 8 and the second section 9 of the column are in a straight line and there is a gap, and this gap is slightly larger than the height of the main boom 3; the side of the main boom 3 away from the ratchet tightener 1 is an open structure. When using a relatively large U-shaped hanger 13, the U-shaped hanger 13 can pass through the gap between the first section 8 and the second section 9 of the column, more effectively avoiding the U-shaped hanger from getting stuck at the end of the main boom 3.

[0029] During the installation of this example, the length of the steel wire rope 12 that needs to be tightened is relatively short, and the open structure at the end of the main boom away from the ratchet tightener 1 only needs to meet the tightening requirement of the steel wire rope 12.
