Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel, and in particular relates to a dragging device for stainless steel production. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils. When stainless steel pipes are stored, they are stacked together in parallel, which also means that when they are needed, they need to be taken out, and a stainless steel dragging device is required;

[0003] The prior art, such as application number: CN202121283977.0, discloses a novel device for using a dragging device for stainless steel production, which drags the stainless steel pipe by clamping the position on the stainless steel pipe body;

[0004] As for the stacked stainless steel pipes, the ends of these stainless steel pipes are relatively flat and the size of the exposed pipe body is smaller, so it is not very convenient to drag them. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a dragging device for stainless steel production, which solves the technical problems raised in the technical background by clamping and dragging the end of a stainless steel pipe.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dragging device for stainless steel production, comprising a dragging device shell, one end of the dragging device shell is vertically fixed with a handle one, the dragging device shell is provided with a stainless steel pipe socket, the stainless steel pipe socket extends from the end of the dragging device shell toward one end of the handle one, the driving installation groove is symmetrically fixed with a rotating shaft at positions on both sides of the stainless steel pipe socket, the rotating shaft is rotatably driven and connected with a rotating shaft rod, and an eccentric circular arc tooth is fixedly provided at one end of the two rotating shaft rods, and the distance from the circular arc tooth surface of the eccentric circular arc tooth close to the handle one side to the rotating shaft is greater than the distance from the circular arc tooth surface of the eccentric circular arc tooth away from the handle one side to the rotating shaft;

[0007] Holding handle one, holding the device in one hand, insert the stainless steel pipe socket of the device into the side of the end of the stainless steel pipe, and the side of the end of the stainless steel pipe passes through the position between the two eccentric circular arc teeth. The two eccentric circular arc teeth are rotated to make the tooth surfaces of the two eccentric circular arc teeth get closer and closer until the tooth surfaces of the two eccentric circular arc teeth are squeezed on the side of the end of the stainless steel pipe, thereby fixing the steel pipe. As handle one is pulled to drag, the two eccentric circular arc teeth squeeze the side of the steel pipe more firmly, and the end of the stainless steel pipe can be dragged by pulling handle one, thereby realizing the dragging of the stainless steel pipe workpiece from the end of the stainless steel pipe, solving the technical problems raised in the technical background.

[0008] Optionally, a tension spring is installed on a side of the pull rod away from the handle, one end of the tension spring is fixedly connected to the pull rod, and the other end of the tension spring is fixedly connected to the housing of the towing device;

[0009] The tension spring is used to pull the pull rod to slide on the towing device housing, so that the pull rod pushes the connecting rod to move, and the connecting rod pushes the rotating shaft to rotate relative to the rotating shaft, and the arc tooth surfaces between the two eccentric arc teeth are separated, thereby facilitating the loosening of the stainless steel pipe and removing the device from the steel pipe.

[0010] Optionally, a rubber sleeve 1 is provided on the handle 1;

[0011] By sleeve-arranging a rubber sleeve on the handle, the hand-held device is made more comfortable.

[0012] Optionally, the handle 1 is replaced with a battery shell, an electric telescopic rod is connected between the battery shell and the pull rod, a cylinder of the electric telescopic rod is fixedly connected to the battery shell, a piston rod of the electric telescopic rod is fixedly connected to the pull rod, and a battery for providing electrical energy to the electric telescopic rod is detachably installed in the battery shell;

[0013] The electric telescopic rod is set to telescope and push and pull the pull rod, so that the pull rod pushes and pulls the rotating shaft rod through the connecting rod to rotate relative to the rotating shaft, thereby clamping or loosening the stainless steel pipe. By replacing manual operation with electric operation, the convenience of use is increased and the use is more labor-saving.

[0014] Optionally, a handle 2 is fixedly provided at the bottom end of the battery shell, and the device is held by holding the handle 2.

[0015] Optionally, a rubber sleeve 2 is provided on the handle 2, and the provision of the rubber sleeve 2 makes it more comfortable to hold the rubber sleeve 2, and the pressure on the palm is less when dragging the stainless steel pipe.

[0016] In summary, compared with the prior art, the beneficial effects of this solution are:

[0017] 1. By inserting the stainless steel pipe socket of the device into the side of the end of the stainless steel pipe, the side of the end of the stainless steel pipe passes through the position between the two eccentric arc teeth, and the two eccentric arc teeth are rotated to clamp and fix the steel pipe, and the end of the stainless steel pipe can be dragged by pulling the handle, so that the stainless steel pipe workpiece can be dragged out from the end of the stainless steel pipe, solving the technical problems raised in the technical background.

A shaft 13, a rotating shaft rod 20 is rotatably connected on the rotating shaft 13, and an eccentric circular arc tooth 21 is fixedly connected to the end of the two rotating shaft rods 20 that are close to each other, and the distance between the circular arc tooth surface of the eccentric circular arc tooth 21 close to the handle 15 and the rotating shaft 13 is greater than the distance between the circular arc tooth surface of the eccentric circular arc tooth 21 away from the handle and the rotating shaft 13, and the two 20 are pulled to rotate by the two 22 respectively, so that the tooth surfaces of the two eccentric circular arc teeth 21 are closer and closer, and the tooth surfaces of the two eccentric circular arc teeth 21 are gradually and tightly squeezed on the side of the end of the stainless steel pipe;

[0025] Holding the handle 15 and the device in one hand, the stainless steel pipe socket 12 of the device is inserted into the side of the end of the stainless steel pipe. The side of the end of the stainless steel pipe passes through the position between the two eccentric circular arc teeth 21. The two eccentric circular arc teeth 21 are rotated to make the tooth surfaces of the two eccentric circular arc teeth 21 closer and closer until the tooth surfaces of the two eccentric circular arc teeth 21 are squeezed on the side of the end of the stainless steel pipe, thereby fixing the steel pipe. As the handle 15 is pulled and dragged, the two eccentric circular arc teeth 21 squeeze the side of the steel pipe more firmly, and the end of the stainless steel pipe can be dragged by pulling the handle 15, so that the stainless steel pipe workpiece can be dragged out from the end of the stainless steel pipe, solving the technical problems raised in the technical background.

[0026] A connecting rod 22 is connected to the ends of the two rotating shaft rods 20 that are far away from each other. A pull rod 23 is vertically provided in the driving installation groove 11 near the handle 15.

[0033] The electric telescopic rod 32 is set to telescope and push and pull the pull rod 23, so that the pull rod 23 pushes and pulls the rotating shaft rod 20 to rotate relative to the rotating shaft 13 through the connecting rod 22, thereby clamping or loosening the stainless steel pipe. By replacing manual operation with electric operation, the convenience of use is increased and the use is more labor-saving.

[0034] In this embodiment, a second handle 41 is fixedly provided at the bottom end of the battery shell 30 . In this embodiment, the device is held by holding the second handle 41 .
