Description

Technical Field

[0001] The utility model relates to the technical field of bundling devices, in particular to a bundling device for threaded steel pipes. Background Art

[0002] Threaded steel pipes are needed in production and infrastructure construction. During transportation, multiple steel pipes need to be bundled together using a bundling device. Before bundling, most of the existing bundling devices stack the steel pipes manually. However, manual stacking easily causes the steel pipes to become loose, resulting in poor bundling in the later stage. Therefore, we made improvements and proposed a bundling device for aluminum steel pipes.

[0003] The patent publication number is CN214397422U. The technical solution disclosed in this patent document is as follows: A bundling device for threaded steel pipes, which relates to the field of bundling devices. The following solution is proposed. It includes a workbench and side workbenches. Two side workbenches are fixedly installed on both sides of the workbench. A chute is opened between the side workbench and the workbench. A slider is slidably installed in the chute. The slider is provided with a spring located in the chute. A first stabilizing plate is fixedly installed on the left slider, and a second stabilizing plate is fixedly installed on the right slider. A tightening hole is formed between the first stabilizing plate and the second stabilizing plate. An installation block is fixedly installed on the workbench. A threaded rod is threadedly installed on the installation block. The threaded rod is fixedly installed with a pushing plate. A bundling table is fixedly installed on the workbench. The bundling table is located between the two side workbenches on both sides. Through this setting, the traditional manual bundling method is changed, making the bundling firm and stable.

[0004] The above patent has the following deficiencies: When the device is in use, due to spring clamping, when the worker exerts force to bundle, the threaded steel pipe drives the spring to swing back and forth, resulting in a gap in the middle of the threaded steel pipe during bundling. In view of this, we propose a bundling device for threaded steel pipes. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a bundling device for threaded steel pipes.

[0006] To achieve the above object, the utility model provides the following technical solution: A bundling device for threaded steel pipes, including a base.

The bottom of the inner wall of the groove is fixedly connected with a rotating rod. The outer wall of the rotating rod is rotatably connected with a circular gear through a bearing.

[0007] Preferably, a clamping block is fixedly connected to the top of the slider. A semi-circular clamping groove is formed on the right side of the clamping block. The circular gear and the rack are meshed with each other.

[0008] Preferably, a support plate is fixedly connected to the front of the base. A hydraulic cylinder is fixedly connected to the top of the support plate. The back of the output end of the hydraulic cylinder is fixedly connected to a connecting plate. The back of the connecting plate is fixedly connected to a connecting rod. The connecting rod movably penetrates through the base and extends towards the back. The extending end is fixedly connected to the back of the slider. The connecting rod is cast in an integrated manner, which improves the integrity. There is no interface inside, and there is no weakness problem at the interface. No assembly is required, and it can be directly installed, which is convenient for production, manufacturing and maintenance.

[0009] Preferably, the fixing device includes a fixing plate. The fixing plate is fixedly connected to the top of the base. A threaded rod penetrates through the right side of the fixing plate. A knob is fixedly connected to the left side of the threaded rod.

[0010] Preferably, a sliding groove is formed on the top of the base. A limiting block is slidably connected to the inner wall of the sliding groove. A clamping plate is fixedly connected to the top of the limiting block.

[0011] Preferably, the right side of the threaded rod is rotatably connected to the left side of the clamping plate through a bearing. The sliding groove and the limiting block are in a T shape. The limiting block is cast in an integrated manner, which improves the integrity. There is no interface inside, and there is no weakness problem at the interface. No assembly is required, and it can be directly installed, which is convenient for production, manufacturing and maintenance.

[0012] Compared with the prior art, the utility model provides a device for bundling threaded steel pipes, which has the following beneficial effects:

[0013] First, for the device for bundling threaded steel pipes, by starting the hydraulic cylinder on the top of the support plate, the output end of the hydraulic cylinder drives the connecting plate to move towards the back. The connecting plate drives the connecting rod to move towards the back. The connecting rod drives the slider to move towards the back. The slider drives the clamping block to move towards the back. When the slider moves towards the back, it drives the rack to move towards the back. The rack drives the circular gear to rotate. The circular gear drives the rack on the left side to move towards the front. The rack drives the slider and the clamping block at the back to fix the threaded steel pipe, so as to reduce the occurrence of the situation that the steel pipe becomes loose and the subsequent bundling is not firm.

[0014] Second, for the device for bundling threaded steel pipes, by rotating the knob to drive the threaded rod to rotate, the threaded rod drives the clamping plate to move towards the right side. When the clamping plate moves, it drives the limiting block at the bottom to slide on the inner wall of the sliding groove, thereby restricting the moving track of the clamping plate and realizing the fixation of both ends of the threaded steel pipe.
