Description

Technical Field

[0001] The utility model relates to the technical field of balancers, in particular to a tracheal balancer. Background Art

[0002] Balancers are widely used in various production lines. They mainly use the energy stored in their internal coil springs to offset the tension of the wire rope and the gravity of the objects hung on the balancer, so that the objects are in a weightless state and can move freely up and down. Therefore, on some production lines, pneumatic tools are connected to the free end of the wire rope of the balancer, so that the balancer can ensure that workers can use pneumatic tools more conveniently, improving work efficiency and work quality. However, in actual application, since pneumatic tools need to be connected to the air source through an air pipe, the air pipe is easy to get entangled with the wire rope during the lifting process, affecting normal use. Therefore, a trachea balancer is developed. Utility Model Content

[0003] The utility model aims to provide a trachea balancer, which solves the technical problem that the steel wire rope of the balancer at the current stage is easy to be entangled with the steel wire rope of the balancer.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses an air pipe balancer, comprising an outer cover body, one end of the outer cover body is an open structure and is provided with a rear end cover matched therewith, an air inlet interface is provided in the middle of the rear end cover, and the air inlet interface is communicated with a first air pipe; a central axis is rotatably provided inside the outer cover body and a spring cover is provided on the outer side of the central axis, a coil spring matched with the central axis is provided in the spring cover; a step pulley is sleeved on the middle part of the central axis, a spiral groove is provided on the outer peripheral wall of the step pulley, a second air pipe matched therewith is wound around the spiral groove, one end of the second air pipe is communicated with the air inlet interface, and the other end of the second air pipe extends to the outside of the outer cover body and is provided with a pneumatic tool.

[0006] Furthermore, a hook is fixedly provided on the upper portion of the outer cover.

[0007] Furthermore, a transmission box is arranged outside the end of the outer cover away from the rear end cover, one end of the central axis extends into the transmission box and is provided with a worm gear, a worm matched with the worm gear is rotatably arranged inside the transmission box, and a motor for driving the worm gear to rotate is arranged outside the transmission box.

[0008] Furthermore, one end of the air inlet interface located inside the outer cover is connected to one end of a retractable bellows, and one end of the bellows is connected to one end of the second air pipe.

[0009] Furthermore, two mounting plates are symmetrically fixedly arranged on the outside of the outer cover, and a roller is rotatably arranged between the two mounting plates.

[0010] Compared with the prior art, the beneficial technical effects of the utility model are:

[0011] When the utility model is working, the second air pipe can be pulled out along the tower wheel by pulling the air tool downward. In this process, the tower wheel is generated and the coil spring matched with the middle shaft is compressed. After the operation is completed, the force on the air tool is released, and the middle shaft and the tower wheel are reversely rotated under the restoring force of the coil spring, so that the second air pipe is retracted, and the air tool is automatically raised and returned to its original position. The air pipe wound on the balancer tower wheel is directly connected to the air tool, and no wire rope connection is required, so the wire rope will not be entangled with the air pipe, ensuring the normal use of the air tool and the balancer.

[0012] In addition, the outer cover of the present application is provided with a roller for rotation, and the extended second air pipe contacts the roller when it moves, which can avoid the second air pipe from being damaged by friction due to direct and long-term contact with the outer cover during movement, thereby increasing the service life of the air pipe.

[0017] like Figure 1-Figure 2 As shown, a trachea balancer comprises an outer cover 1, one end of which is an open structure and a rear end cover 2 adapted thereto is mounted via detachable bolts. An air inlet interface 3 is provided in the middle of the rear end cover 2, the air inlet interface 3 is connected to one end of a first trachea 4, and the other end of the first trachea 4 is connected to an air supply source.

[0018] A central axis is rotatably mounted inside the outer cover body 1 and a spring cover is arranged on the outside of the central axis. A coil spring matching the central axis is installed in the spring cover. The above structural arrangement of the utility model is the same as that of the balancer in the prior art, so it will not be described in detail.

[0019] A step pulley 5 is sleeved on the middle part of the central axis, a spiral groove 6 is opened on the outer peripheral wall of the step pulley 5, a second air pipe 7 adapted thereto is wound around the spiral groove, one end of the second air pipe 7 is connected to the air inlet interface 3, and the other end of the second air pipe 7 extends to the outside of the outer cover 1 and is installed with a pneumatic tool 8.

[0020] A hook 9 is fixedly provided on the upper portion of the outer cover 1 .

[0021] When the utility model is used, the balancer is fixed to the hanging hole of the workshop load-bearing beam or the hanging hole of the rail car through the hook 9, and the worker can pull the second air pipe outward along the tower wheel by pulling the pneumatic tool downward. During this process, the tower wheel is generated and the coil spring matched with the middle shaft is compressed. After the operation is completed, the force on the pneumatic tool is released, and the middle shaft and the tower wheel rotate in the opposite direction under the restoring force of the coil spring, so that the second air pipe is retracted, and the pneumatic tool is automatically raised and returned to its original position.

[0022] In this embodiment, a transmission box 10 is arranged outside the end of the outer cover 1 away from the rear end cover 2, one end of the central shaft extends into the transmission box 10 and a worm wheel is installed at the end, a worm matched with the worm wheel is rotatably installed inside the transmission box 10, and a motor 11 for driving the worm to rotate is installed outside the transmission box 10. Through the above arrangement, the balancer worm has a certain self-locking function during the transmission process of the balancer, which can prevent the load from rotating in reverse and reversing, and the balancer worm can reduce the impact force and vibration during the transmission process, effectively offset the unbalanced load during the transmission process, and protect the normal operation of the mechanical equipment.

[0023] The air inlet interface 3 in this example is located at one end of the outer cover 1 and is connected to one end of a retractable bellows 12, and one end of the bellows 12 is connected to one end of the second air pipe 7. The air inlet interface 3 and the second air pipe 7 are connected by the bellows, and the retractable bellows can meet the range of motion of the end of the second air pipe when it rotates with the tower wheel.

[0024] In addition, two mounting plates 13 are symmetrically fixedly arranged on the outside of the outer cover 1, and a roller 14 is rotatably arranged between the two mounting plates 13. The arrangement of the roller can avoid direct contact between the second air pipe 7 and the outer cover during the activity, and avoid the second air pipe 7 being damaged due to friction for a long time and affecting the service life.
