Description

Technical Field

[0001] The invention relates to the technical field of interface docking auxiliary devices, and in particular to an auxiliary device for a bellows interface docking. Background Art

[0002] The bellows docking process refers to the steps of connecting two or more bellows. Bellows is a pipe used to transport liquids or gases. It has good elasticity and pressure resistance. During the production process, bellows are widely used in petrochemical, medical equipment, aerospace, automobile manufacturing and other fields.

[0003] The existing bellows docking device has the following defects:

[0004] ①First, when the existing bellows are in use, it is often necessary to connect the two bellows to achieve the connection of the pipeline, and this process is mostly carried out manually. When the bellows are connected by artificial external force, there are many uncontrollable factors such as sudden slipping during the connection process, which will not only cause errors in the connection of the bellows, but also the force cannot be well controlled during the connection, resulting in gaps in the connection parts of the pipelines during the connection process, thereby reducing the sealing performance of the bellows after connection, which will affect the subsequent normal use of the bellows in the long run.

[0005] ② In addition, the docking of the bellows may fail due to the height difference, and the bellows cannot be kept at the same horizontal plane through human intervention, so the precise docking effect cannot be achieved at one time. It usually takes multiple attempts, which is not conducive to the efficient docking of batch bellows.

In this way, during the manual docking process of the bellows, the gap between the two tubes can be reduced when docking, thereby reducing the sealing performance. At the same time, it has a tightening characteristic to ensure the stability of the bellows docking.

[0020] (2) The present invention provides a sliding mechanism. When the pulley moves on the second slide rail, it will drive the pulley to reach the open trapezoidal structure installed inside it. At this time, the right fastener of the pulley will be squeezed by the open trapezoidal block and embedded in the open trapezoidal block under the action of the spring, so that the lifting platform can achieve the limit function. At the same time, it also makes it more convenient and labor-saving for manpower to dock the corrugated pipe, ensuring the reasonable limit function of the device and the safety of the device;

[0021] (3) The present invention ensures that the lifting platform clearly presents height information during movement through the cooperation between the lever and the caliper, so that the staff can accurately grasp the flush docking of the interfaces at both ends of the bellows, thereby laying the foundation for a smooth experience in subsequent use;

[0022] (4) The core of this invention lies in the ingenious integration of the telescopic moving plate and the rotating wheel, which enables the bellows to be stably supported on the device and the range of movement to be flexibly adjusted, thus laying a solid foundation for achieving stable operation.

The staff prepares two bellows before use, first placing one bellows aside, and then placing the other bellows on the lifting platform 1. By moving the lifting platform 1, the bellows are in a horizontal direction. Because the pulley 32 is installed at the bottom of the lifting platform 1 and the slide rail 2 31 is installed at the lower end of the pulley 32, the device can be adjusted, the range of activity is increased and the stability of the device is guaranteed;

[0042] At the same time, the staff rotates the handle 12 on the left side of the lifting platform 1 to rotate the two-way screw 14. Under the rotation of the two-way screw 14, the movable plate 13 connected to the outside of the two-way screw 14 drives the folding plates 11 on both sides of the lifting platform 1 to rise and fall, and the lever 41 set on the outer walls of both sides of the folding plate 11 and the caliper 51 set on the outer walls of both sides of the lifting platform 1 allow the staff to clearly see the lifting height while the lifting platform 1 is moving, thereby ensuring that the interfaces at both ends of the corrugated pipe are butted flush, which is convenient for subsequent use. The pipe body push docking mechanism 2 also includes: a small gear 24, a screw rod 26, a fixed block 27, a fixed plate 28, and a large gear 29. The outer walls of both sides of the upper end of the lifting platform 1 are fixedly installed with fixed plates 28, a large gear 29 is set on the left side of the fixed plate 28, and a small gear 24 is set on the right side of the large gear 29. The center of the small gear 24 is fixed A screw rod 26 is fixedly installed, and a fixed block 27 is rotatably installed on the left side of the small gear 24. The small gear 24 meshes with the large gear 29, and the large gear 29 meshes with the tooth groove 210. A rotating rod fixedly installed with the bottom end of the fixed plate 28 is arranged at the center of the large gear 29. One end of the screw rod 26 is fixedly installed on the outer wall of the bottom end of the arc-shaped baffle 213, and the other end of the screw rod 26 penetrates the fixed plate 28 and is fixedly installed on the outer wall of the fixed plate 28.

A telescopic rod 25 is fixedly installed on one end of the telescopic motion plate 21. The movement of the rotating wheel 23 on the slide rail 22 makes it more labor-saving and convenient to dock the corrugated pipe by manpower.

[0043] A pull-out plate 215 is fixedly installed on the outer wall of one end of the lifting platform 1, and a T-shaped groove 216 is symmetrically opened on the inner wall of one side of the pull-out plate 215. Through manual pushing and pulling, another corrugated pipe can be placed stably as a whole. Since tooth grooves 210 are fixedly installed on both sides of the telescopic motion plate 21, the two sides of the tooth grooves 210 are meshed with large gears 29, and the right side of the large gear 29 is meshed with a small gear 24, when the manually operated corrugated pipe is docked on the telescopic motion plate 21, the large gear 29 is rotated while driving the small gear 24 to rotate, and a screw rod is fixedly installed inside the small gear 24. 26, the outer rotation of the screw rod 26 is connected to the fixed block 27, so that when the pinion 24 rotates, the screw rod 26 is driven to rotate, and the rotation of the screw rod 26 drives the fixed block 27 to rotate, and one end of the screw rod 26 is fixedly connected to the inner wall of the bottom end of the arc-shaped baffle 213. Since the bottom end of the arc-shaped baffle 213 is fixedly installed with an arc-shaped ladder block 211 and the arc-shaped ladder block 211 is slidably connected to the inside of the slide groove 212, the fixed block 27 pushes the arc-shaped baffle 213 to move to the left, thereby reducing the gap between the two pipes during the manual docking of the corrugated pipes, and playing a clamping role;

[0044] The present invention provides a tube body pushing docking mechanism 2. When the bellows moves on the telescopic moving plate 21, the tooth grooves 210 on both sides of the moving plate mesh with the large gear 29 to rotate, and the large gear 29 meshes with the small gear 24, so that the small gear 24 rotates along with the large gear 29, and then the screw rod 26 fixedly installed at the center of the small gear 24 rotates, so that the fixed block 27 outside the screw rod 26 rotates and pushes the arc-shaped baffle 213 to slide on the slide groove 212, thereby reducing the gap between the two tubes during the manual docking of the bellows, playing a clamping role, ensuring the stability of the bellows docking, and improving the practicality of the device;

[0045] The sliding mechanism 3 includes: a second slide rail 31, a pulley 32, a fastener 33, a spring 34, an open trapezoidal block 35, a rotating shaft 36, a buckle 37, and a baffle 38. The bottom end of the lifting platform 1 is fixedly provided with a second slide rail 31, the pulley 32 is slidably installed inside the second slide rail 31, the buckles 37 are clamped on the central outer walls of both sides of the pulley 32, the rotating shaft 36 is fixedly installed on the left side of the buckle 37, and a baffle 38 is arranged above the rotating shaft 36. The fastener 33 is arranged through the center of the baffle 38, and the outer wall of the fastener 33 is fixedly provided with a spring 38. 4, an open trapezoidal block 35 is fixedly connected to one end of the pulley 32, a baffle 38 is fixedly installed on one end of the inner wall of the spring 34, the diameter of the fastener 33 is the same as the opening size of the open trapezoidal block 35, a lever 41 is symmetrically fixed to the outer wall of the folding plate 11, a caliper 51 is fixed to the left side of the lever 41, and the caliper 51 is fixedly installed on both sides of the outer wall of the lifting platform 1, and an open trapezoidal block 35 is fixedly installed on one side of the inner side of the slide rail 2 31, so that when the pulley 32 moves the open trapezoidal block 35 on the slide rail 2 31, the fastener 33 on the right side of the pulley 32 The fastener 33 is squeezed by the open trapezoidal block 35 and inserted into the open trapezoidal block 35 under the action of the spring 34, thereby limiting the lifting platform 1, and buckles 37 are provided on the outer walls of both sides of the pulley 32, and a baffle 38 is fixedly installed on the outside of the fastener 33, and a rotating shaft 36 is clamped on the inner side of the buckle 37, so that by manually stepping on the baffle 38, the buckle 37 is turned over to lock the pulley 32, thereby ensuring the limited movement of the device and the safety of the device, thereby improving the practicality of the device. The invention provides a sliding mechanism. When the pulley 32 slides on the slide rail 31 and moves to the open trapezoidal block 35 installed inside the slide rail, the fastener 33 on the right side of the pulley 32 is squeezed by the open trapezoidal block 35 and inserted into the open trapezoidal block 35 under the action of the spring 34, thereby achieving a limiting effect on the lifting platform 1 and making it more labor-saving and convenient to connect the bellows by manpower, ensuring the limited movement of the device and the safety of the device, thereby improving the practicability of the device.

[0046] The complete usage steps and working principle of the above embodiment are as follows:

[0047] The staff prepares two bellows before use. First, one bellows is placed aside, and then the other bellows is placed on the lifting platform 1. The lifting platform 1 is moved so that the bellows is in a horizontal direction. Because a pulley 32 is installed at the bottom of the lifting platform 1 and a slide rail 31 is installed at the lower end of the pulley 32, the device can adjust the range of movement, increase and ensure the stability of the device. At the same time, the staff rotates the handle 12 on the left side of the lifting platform 1 to rotate the two-way screw 14. Under the rotation of the two-way screw 14, the movable plate 13 connected to the outside of the two-way screw 14 drives the folding plates 11 on both sides of the lifting platform 1 to rise and fall. Through the lever 41 set on the outer walls of both sides of the folding plate 11 and the caliper 51 set on the outer walls of both sides of the lifting platform 1, the staff can clearly see the height of the lifting platform while the lifting platform 1 is moving, thereby judging the height between the two bellows, ensuring that the interfaces at both ends of the bellows are connected and flush, which is convenient for subsequent use.

[0048] Since the bellows is too long, the staff needs to pull out the telescopic motion plate 21 horizontally when docking. The tail end of the bellows can also be placed on the telescopic motion plate 21, so that one bellows can be placed stably as a whole. A rotating wheel 23 is fixedly installed at the bottom end of the telescopic motion plate 21, and a slide rail 22 is provided at the upper end of the lifting platform 1. A telescopic rod 25 is fixedly installed at one end of the telescopic motion plate 21. Through the movement of the rotating wheel 23 on the slide rail 22, it is more labor-saving and convenient to dock the bellows by manpower. A pull-out plate 215 is fixedly installed on the outer wall of one end of the lifting platform 1, and a T-slot 216 is symmetrically provided on the inner wall of one side of the pull-out plate 215. Through manual pushing and pulling, another bellows can be placed stably as a whole. Since tooth grooves 210 are fixedly installed on both sides of the telescopic motion plate 21, the two sides of the tooth grooves 210 are meshed with large gears 29, and the right side of the large gear 29 is meshed with small gears. The gear 24 enables the large gear 29 to rotate while driving the small gear 24 to rotate when the bellows is manually operated to dock on the telescopic motion plate 21, and the screw rod 26 is fixedly installed inside the small gear 24, and the external thread of the screw rod 26 is connected to the fixing block 27, so that when the pinion 24 rotates, the screw rod 26 is driven to rotate, and the rotation of the screw rod 26 drives the fixing block 27 to rotate, and one end of the screw rod 26 is fixedly connected to the inner wall of the bottom end of the arc-shaped baffle 213. Since the bottom end of the arc-shaped baffle 213 is fixedly installed with an arc-shaped ladder block 211 and the arc-shaped ladder block 211 is slidably connected to the inside of the slide groove 212, the fixing block 27 pushes the arc-shaped baffle 213 to move leftward, so that the arc-shaped baffle 213 fits the outer wall of the bellows, thereby reducing the gap between the two pipes after docking during the manual docking of the bellows, playing a clamping role, ensuring the stability of the bellows docking, and improving the practicality of the device;

[0049] An open trapezoidal block 35 is fixedly installed on one side of the inner side of the second slide rail 31, so that when the pulley 32 moves on the second slide rail 31 to the open trapezoidal block 35, the fastener 33 on the right side of the pulley 32 hits the inclined surface of the trapezoidal block 35 and is squeezed to compress the spring 34. At the same time, the compression of the spring 34 will give the fastener 33 an upward force. When the pulley 32 moves to the top of the open trapezoidal block 35, the compressed spring 34 will reset and drive the fastener 33 to move downward, so that the fastener 33 is inserted into the open trapezoidal block 35. In the embodiment of the present invention, the bottom of the lifting platform 1 is locked and cannot move forward, thereby limiting the lifting platform 1, and buckles 37 are provided on the outer walls of both sides of the pulley 32, and a baffle 38 is fixedly installed on the outside of the fastener 33, and a rotating shaft 36 is clamped on the inner side of the buckle 37, so that by manually stepping on the baffle 38, the buckle 37 is flipped, and then the entire pulley 32 is lifted, and the pulley 32 cannot move forward, thereby ensuring the limitation of the movement of the device and the safety of the device, thereby improving the practicability of the device.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
