Description

Technical Field

[0001] The utility model relates to the technical field of steel belt processing, in particular to an axis telescopic device for a steel belt shaft of a traction machine. Background Technique

[0002] The traction of a vertical lift elevator is usually realized by a traction machine and a steel belt rope. The traction wheel is generally installed outside the main shaft of the motor. The rotation of the traction wheel realizes the traction of the steel belt rope to control the up and down movement of the elevator car. The steel belt is generally used for packaging, commonly known as a bundling belt. It is a strip-shaped packaging material with high tensile strength and a certain elongation rate, and is widely used in the steel, non-ferrous metal, petrochemical, construction and glass industries, and the demand is extremely wide. During the production process of the steel belt, a steel belt shaft is required to wind up the steel belt.

[0003] However, some existing steel belt shafts do not have the function of conveniently adjusting the length of the axis. When producing steel belts of different widths, the steel belt shaft needs to be disassembled and replaced, which affects the production efficiency of the steel belt. The existing steel belt shaft does not have the function of conveniently adjusting the length of the axis. When producing steel belts of different widths, the steel belt shaft needs to be disassembled and replaced, which affects the production efficiency of the steel belt. At the same time, when the steel belt is wound up, it is not convenient to remove the steel belt shaft, which brings inconvenience to the user. Therefore, we propose an axis telescopic device for a steel belt shaft of a traction machine to solve the above problems. Content of the Utility Model

The same second shaft roller 4 is in movable contact with one side of the two first shaft rollers 3 close to each other. The outer side of the circular plate 2 is rotatably sleeved with a circular ring plate 6 through a bearing 5. A rectangular block 7 is fixedly connected to one side of each of the two circular ring plates 6 away from each other. An L-shaped block 9 is threadedly installed on the top of the rectangular block 7 through a first bolt 8. The top of the L-shaped block 9 is rotatably connected to a connecting rod 10. The tops of the two connecting rods 10 are rotatably connected to the same cross bar 11. The screw 12 is rotatably connected to the inner wall of the top of the U-shaped frame 1. The cross bar 11 is threadedly sleeved on the outer side of the screw 12. The first motor 13 drives the cross bar 11 to squeeze the connecting rod 10 through the screw 12. The connecting rod 10 drives the corresponding L-shaped block 9 to move. The L-shaped block 9 drives the circular ring plate 6 to move through the corresponding rectangular block 7. The circular ring plate 6 drives the corresponding first shaft roller 3 to move through the circular plate 2, thereby increasing the length of the axis. When the winding is completed, reverse the rotation of the first bolt 8 and the second bolt 19, and then it can be moved forward to remove the first shaft roller 3 and the second shaft roller 4 for replacement. It has the function of conveniently adjusting the length of the axis. When producing steel belts of different widths, it is not necessary to disassemble and replace the steel belt shaft. When the steel belt winding is completed, it is convenient to remove the steel belt shaft.

[0021] In this embodiment, specifically: a first motor 13 is fixedly connected to the top of the U-shaped frame 1, and the end of the output shaft of the first motor 13 is fixedly connected to the top end of the screw 12;

[0022] In this embodiment, specifically: cylindrical columns 14 are rotatably connected to the inner walls on both sides of the U-shaped frame 1. Circular blocks 15 are in movable contact with the mutually remote sides of the two circular plates 2. Square rods 16 are fixedly connected to the mutually remote sides of the two circular blocks 15. The cylindrical columns 14 are slidably sleeved on the outer sides of the corresponding square rods 16. A spring 17 which is movably sleeved on the outer side of the square rod 16 is fixedly connected between the end of the cylindrical column 14 and the outer side of the corresponding circular block 15;

[0023] In this embodiment, specifically: connection blocks 18 are fixedly connected to the front side and the rear side of the circular block 15. The connection blocks 18 are threadedly connected to the circular plate 2 through second bolts 19;

[0024] In this embodiment, specifically: two vertical rods 20 are fixedly connected to the inner wall at the top of the U-shaped frame 1. The cross bar 11 is slidably sleeved on the outer sides of the two vertical rods 20;

[0025] In this embodiment, specifically: a second motor 21 is fixedly connected to the right side of the U-shaped frame 1. The end of the output shaft of the second motor 21 is fixedly connected to the right end of one of the cylindrical columns 14 on the right side. Support seats 22 are fixedly connected to both sides of the U-shaped frame 1;

[0026] In this embodiment, specifically: T-shaped sliding rods 23 are fixedly connected to the mutually approaching sides of the two first shaft rollers 3. Two cavities are formed in the second shaft roller 4. The outer side of the T-shaped sliding rod 23 is slidably connected to the side wall of the corresponding cavity.

[0027] When the utility model works: during use, when it is necessary to adjust the length of the axis to match steel belts of different widths, start the first motor 13. The first motor 13 drives the screw rod 12 to rotate when it works. The screw rod 12 drives the cross bar 11 to move downward. The cross bar 11 slides outside the two vertical rods 20. During the movement of the cross bar 11, the two connecting rods 10 are extruded. Under the action of the extrusion force, the connecting rods 10 move and rotate. The connecting rods 10 drive the corresponding L-shaped blocks 9 to move. The L-shaped blocks 9 drive the circular plate 6 to move through the corresponding rectangular blocks 7. The circular plate 6 drives the circular plate 2 to move through the bearing 5. The circular plate 2 drives the square rod 16 to move through the circular block 15. During the movement of the circular plate 2, the spring 17 is compressed. The circular plate 2 drives the corresponding first shaft roller 3 to move. The first shaft roller 3 drives the corresponding T-shaped slide bar 23 to move. The T-shaped slide bar 23 slides in the corresponding cavity. The two first shaft rollers 3 move away from each other, thereby increasing the length of the axis, facilitating the matching of steel belts of different widths. Wind the steel belt outside the two first shaft rollers 3 and the second shaft roller 4. Start the second motor 21. The second motor 21 drives the corresponding square rod 16 to rotate through a cylinder 14 on the right side. The square rod 16 drives the circular block 15 to rotate. The circular block 15 drives the circular plate 2 to rotate. The circular plate 2 drives the corresponding first shaft roller 3 to rotate. The first shaft roller 3 drives the second shaft roller 4 to rotate through the T-shaped slide bar 23 and winds the steel belt. When the winding is completed, rotate the first bolt 8 and the second bolt 19 in the reverse direction. At this time, the first shaft roller 3 and the second shaft roller 4 can be moved forward to be removed and replaced. Thus, a device for telescoping the axis of a steel belt shaft for a traction machine is formed, which has the function of conveniently adjusting the length of the axis. When producing steel belts of different widths, it is not necessary to disassemble and replace the steel belt shaft. When the steel belt winding is completed, it is convenient to remove the steel belt shaft.
