Description

Technical Field

[0001] This utility model belongs to the technical field of steel pipe production line, specifically relating to a batch synchronous stepping mechanism for steel pipes on an inclined platform. Background Technology

[0002] With the development of the manufacturing industry, the production and processing of products in the field of machining requires multiple processes. During the process of moving from one process to the next, transportation is required. How to quickly and accurately transport the workpiece to the workstation is the key to improving work efficiency, processing quality and safe production.

[0003] For a long time, the transfer of steel pipes between processes on the production line has been carried out by freely rolling them from high to low on an inclined platform until they hit the steel pipe and stop moving. This method of transferring steel pipes generates a lot of noise. Moreover, the longer the rolling distance and the faster the steel pipe travels, the greater the noise generated. There are many processes that generate this kind of noise in a factory. The superposition of these noises seriously affects the occupational health of the working environment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mechanism for the batch synchronous stepping of steel pipes on an inclined platform.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a batch synchronous stepping mechanism for steel pipes on an inclined platform, comprising two sets of transfer mechanisms, a synchronous drive mechanism, and four columns. Each set of transfer mechanisms is supported by two columns arranged along the X-axis. The synchronous drive mechanism drives the two sets of transfer mechanisms to move synchronously. Each set of transfer mechanisms includes a first toothed plate and a second toothed plate. The teeth of the first toothed plate and the second toothed plate are staggered, and the tip of the first toothed plate corresponds to the root of the second toothed plate. The synchronous drive mechanism includes a cylinder, an active lever, a transmission shaft, a secondary active lever, a driven lever, and a connecting rod. The middle parts of the active lever, the secondary active lever, and the driven lever are all connected to the columns through the transmission shaft. The telescopic end of the cylinder is hinged to one end of the active lever, and the other end of the cylinder is hinged to the column located on the same side of the active lever. The active lever, the secondary active lever, and the driven lever are all hinged to the first toothed plate and the second toothed plate through the connecting rod.

[0006] Preferably, there are two driven levers, and the two driven levers are coaxial with the driving lever and the secondary driving lever, respectively.

[0007] Preferably, a tie rod is hinged between the active lever and the secondary active lever.

[0008] Preferably, a steel pipe is mounted on the top of the first toothed plate and the second toothed plate, and the steel pipe moves in a direction close to the cylinder.

[0009] Preferably, it also includes an inclined platform located between the two sets of transfer mechanisms, the inclined platform being inclined in the same direction as the movement direction of the steel pipe.

[0010] Preferably, the top of the column is symmetrically provided with outer guide plates, and an inner guide plate is provided at the middle position of the top of the column near the two outer guide plates. The inner guide plate is located between the first toothed plate and the second toothed plate, and the two outer guide plates are respectively located outside the first toothed plate and the second toothed plate.

[0011] Preferably, ball bearings are provided at the outer guide plate and the inner guide plate, and the ball bearings are fixedly connected to the drive shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model adds two sets of parallel toothed plates on the basis of keeping the original inclined platform unchanged, which reduces the amount of work to be changed, and the two sets of toothed plates are controlled by the same power source, so there is no synchronization problem. In addition, only one solenoid valve is needed to control the cylinder, which has low power and simple control. At the same time, the movement of a steel pipe can be completed by a single stroke of the two sets of toothed plates rising or falling through the extension and retraction of the cylinder, avoiding the noise generated by the impact of the steel pipe and solving the problem of noise superposition affecting the working environment and occupational health.

[0014] (2) In this utility model, the synchronous movement of the steel pipe does not leave the inclined platform, and there is no need to lift the steel pipe as in the n-pipe translation. At the same time, there are many steel pipes that can be controlled, and the length can be flexibly made according to the needs of the site. In addition, the toothed groove of the toothed plate has a positioning function, which can directly provide positioning steel pipes for the next process. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-9 As shown, this utility model provides a technical solution: a batch synchronous stepping mechanism for steel pipes on an inclined platform, comprising two sets of transfer mechanisms, a synchronous drive mechanism, and four columns 9. Each set of transfer mechanisms is supported by two columns 9 arranged along the X-axis. The synchronous drive mechanism drives the two sets of transfer mechanisms to move synchronously. Each set of transfer mechanisms includes a first toothed plate 3 and a second toothed plate 4. The teeth of the first toothed plate 3 and the second toothed plate 4 are staggered, and the tips of the teeth of the first toothed plate 3 correspond to the teeth of the second toothed plate 4. The synchronous drive mechanism includes a cylinder 1, an active lever 2, a transmission shaft 6, a secondary active lever 7, a driven lever 8, and a connecting rod 10. The middle parts of the active lever 2, the secondary active lever 7, and the driven lever 8 are all connected to the column 9 via the transmission shaft 6. The telescopic end of the cylinder 1 is hinged to one end of the active lever 2, and the other end of the cylinder 1 is hinged to the column 9 located on the same side as the active lever 2. The active lever 2, the secondary active lever 7, and the driven lever 8 are all hinged to the first toothed plate 3 and the second toothed plate 4 via the connecting rod 10.

[0027] like Figure 7 As shown, the fulcrum of each lever is the central drive shaft 6, and the two ends of each lever near the drive shaft 6 are hinged to the connecting rod 10 with equidistant pins, so that the torque at both ends of the drive shaft 6 is balanced, thus requiring no great force to make each lever rotate up and down.

[0028] Meanwhile, the connection between the active lever 2 and the cylinder 1 is lengthened, which increases the distance between the force application points of the cylinder 1. This helps to save the power of the cylinder 1, thereby achieving a larger torque with a larger stroke. At the same time, it ensures that the other toothed plate must descend by the same amount as one toothed plate rises.

[0029] like Figure 4 As shown, there are two driven levers 8, and the two driven levers 8 are coaxial with the driving lever 2 and the secondary driving lever 7 respectively. The two driven levers 8 are connected to the driving lever 2 and the secondary driving lever 7 through the transmission shaft 6, which facilitates the synchronous movement of the two driven levers 8 with the driving lever 2 and the secondary driving lever 7.

[0030] like Figure 1 As shown, a pull rod 5 is hinged between the active lever 2 and the secondary active lever 7, and the pull rod 5 connects the active lever 2 and the secondary active lever 7 to achieve synchronous movement of the active lever 2 and the secondary active lever 7.

[0031] like Figure 2 As shown, a steel pipe 11 is mounted on the top of the first toothed plate 3 and the second toothed plate 4. The steel pipe 11 moves in the direction close to the cylinder 1. The synchronous stepping of multiple steel pipes 11 is achieved through the coordinated movement of the first toothed plate 3 and the second toothed plate 4.

[0032] like Figure 3 As shown, it also includes an inclined platform 12 located between the two sets of transfer mechanisms. The inclined direction of the inclined platform 12 is consistent with the moving direction of the steel pipe 11, so that the steel pipe 11 can move synchronously without leaving the inclined platform 12.

[0033] like Figure 9 As shown, the top of the column 9 is symmetrically provided with outer guide plates 13, and an inner guide plate 14 is provided at the middle position of the top of the column 9 near the two outer guide plates 13. The inner guide plate 14 is located between the first toothed plate 3 and the second toothed plate 4. The two outer guide plates 13 are located on the outside of the first toothed plate 3 and the second toothed plate 4, respectively. The inner guide plate 14 and the outer guide plate 13 provide guiding function for the toothed plates.

[0034] Ball bearings are provided at the outer guide plate 13 and the inner guide plate 14. The ball bearings are fixedly connected to the drive shaft 6, which helps to avoid wear of the drive shaft 6 and the impact of wear-induced gaps on synchronization.

[0035] The working principle and usage process of this utility model are as follows: When in use, the steel pipe 11 is placed from the highest point of the inclined platform 12, and the steel pipe 11 is placed on the first toothed plate 3 and the second toothed plate 4. When the cylinder 1 extends, the extension end of the cylinder 1 drives the active lever 2 and the end of it that is hinged to it to rotate from the inclined downward state to the inclined upward state. At the same time, the active lever 2 drives the secondary active lever 7 to move synchronously through the pull rod 5, and drives the two driven levers 8 to move synchronously through the transmission shaft 6, thereby realizing the synchronous rotation of the active lever 2, the secondary active lever 7 and the two driven levers 8. The active lever 2, the secondary active lever 7 and the two driven levers 8 will synchronously drive the two sets of first toothed plates 3 and second toothed plates 4 to move up and down, thereby realizing the synchronous stepping movement of the steel pipe 11.

[0036] Specifically, the principle of synchronous stepping motion of steel pipe 11 is as follows:

[0037] like Figure 1-3 As shown, in the initial position of cylinder 1, a set of first toothed plates 3 are at the top and second toothed plates 4 are at the bottom. As cylinder 1 extends, under the action of the active lever 2, the secondary active lever 7, and the two driven levers 8, the first toothed plate 3 gradually descends, while the second toothed plate 4 rises synchronously. When the tips of the teeth of the second toothed plate 4 exceed the inclined platform 12, the steel pipe on the right side will enter the synchronous translation column. As the action continues, the space between the toothed plates gradually shifts to the left. When cylinder 1 is half-stroked, the first toothed plate 3 and the second toothed plate 4... When the two toothed plates 4 are at the same height, the cylinder 1 continues to extend, the first toothed plate 3 continues to descend, the second toothed plate 4 continues to rise, and the tube space continues to move to the left. When the tip of the tooth of the first toothed plate 3 on the left is lower than the inclined platform 12, one steel pipe 11 on the left is released, completing the storage of one steel pipe 11 on the right and the release of one steel pipe 11 on the left. Similarly, when the cylinder 1 descends, it completes the storage of one steel pipe 11 on the right and the release of one steel pipe 11 on the left. This cycle is repeated to achieve synchronous stepping movement of multiple steel pipes 11 along the inclined platform 12.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
