Through manual control, the sides of the pipe fittings are all polished smooth. As the working time increases, the hands of the construction workers will be sore and fatigued, which reduces the grinding efficiency and quality. At the same time, there are certain safety risks when grinding hand-held pipe fittings on the grinding head, which is very unsafe for construction workers and increases the labor intensity of construction workers, which is not conducive to batch grinding of small-sized pipe fittings.

[0017] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] like Figure 1As shown, the utility model is a small pipe clamping device for an offshore oil platform, and its operating platform 101, clamping device 102, and clamping assembly 105 can clamp small pipes, which is convenient for construction workers to grind, and makes up for the problem that small pipes cannot be fixed during grinding. Specifically, it includes an operating platform 101, a clamping device 102, and a clamping assembly 105. The operating platform 101 is horizontally arranged and is an I-beam structure, a trapezoidal platform structure, or a rectangular platform structure. When in use, the base of the operating platform 101 is horizontally placed on the platform deck. The clamping device 102 includes a fixing unit 103 and a clamping mechanism 104. The base of the fixing unit 103 is connected to the operating platform 101. Specifically, one end of the fixing unit 103 is connected to the operating platform 101, and the other end is threadedly connected to the adjusting stud 09 provided on the clamping mechanism 104. The lower end of the clamping mechanism 104 is provided with a clamping assembly 105. At the same time, the clamping assembly 105 is horizontally arranged, and the clamping mechanism 104 is vertically arranged above the clamping assembly 105. The clamping assembly 105 includes a connecting piece 05 and a clamping panel 06. The upper end of the connecting piece 05 is detachably connected to the adjusting stud 09, and the lower end is connected to the upper clamping piece of the clamping panel 06. The lower clamping piece of the clamping panel 06 is installed on the operating platform 101. The detachable connection mode of the connecting piece 05 makes the whole device easy to disassemble and store. In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] The fixing unit 103 includes a fixing stud 01, a fixing nut 08, a cross bar and a clamping nut 04. The lower end of the fixing stud 01 is fixedly mounted on the operating platform 101, preferably by welding. The upper end of the fixing stud 01 is threadedly connected with a fixing nut 08, and a cross bar is horizontally connected to the side wall of the fixing nut 08. The end of the cross bar away from the fixing nut 08 is connected with a clamping nut 04, which is convenient for locking the adjustment stud 09 of the clamping mechanism 104. The cross bar is a steel pipe structure. Preferably, a lock nut 03 is connected to the fixing stud 01, and the lock nut 03 is arranged below the fixing nut 08, and the lock nut 03 is arranged closely to the fixing nut 08. When the operator polishes the small pipe fittings, the small pipe fitting clamping device for offshore oil platforms described in the utility model will generate certain vibrations or impacts. The presence of the lock nut 03 can effectively prevent the fixing nut 08 from loosening, thereby improving the stability and reliability of the device.

[0021] A reinforcement piece 02 is disposed on the outside of one end of the fixing stud 01 that is connected to the operating platform 101. The presence of the reinforcement piece 02 can strengthen the bottom connection of the fixing stud 01 to a certain extent, thereby ensuring that the connection of the fixing stud 01 is more stable and reliable. The reinforcement piece 02 can be a nut structure, which is directly threaded on the fixing stud 01, and the lower end of the nut structure is welded to the operating platform 101; the reinforcement piece 02 can also be a reinforcement rib, and a plurality of reinforcement ribs are evenly distributed around the bottom of the fixing stud 01, and then the reinforcement ribs are respectively welded to the operating platform 101 and the fixing stud 01. The number of reinforcement pieces 02 is multiple. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0022] The clamping mechanism 104 includes a torsion bar 07 and an adjusting stud 09. The upper end of the adjusting stud 09 is connected to the torsion bar 07, and the lower end passes through the clamping nut 04 and is threadedly connected to the clamping nut 04. By rotating the torsion bar 07, the adjusting stud 09 can make a vertical linear motion above the clamping assembly 105.

[0023] The upper end of the upper clamp is provided with a connector 05, which is detachably connected to the adjusting stud 09. Preferably, the connector 05 is a nut, and the thread of the threaded hole of the nut is ground off, that is, the threaded hole is ground into a light hole. The lower end of the nut is welded to the upper clamp, and the upper end is directly sleeved on the adjusting bolt. Since the center hole of the connector 05 is a light hole structure, it is convenient to take the upper clamp.

[0024] The upper clamp and the lower clamp are respectively provided with arc surface structures, and the arc surface structure of the upper clamp is arranged face to face with the arc surface structure of the lower clamp. The existence of the arc surface structure makes the small pipe fittings more stable and reliable when they are compressed, and the fit is better. In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, and it can be the internal connection of the two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] In the actual working process, the construction personnel can adjust the upper and lower heights of the fixing stud 01 by rotating the torsion bar 07, so as to adjust the distance between the upper clamp and the lower clamp of the clamping assembly 105. When the distance between the upper clamp and the lower clamp is sufficient to place small pipe fittings, the small pipe fittings to be polished are placed on the arc surface structure of the lower clamp, and the end of the small pipe fittings to be polished needs to extend out of the clamping assembly 105. Then, the torsion bar 07 is rotated to lower the upper clamp until the pre-polished small pipe fittings are clamped, and then the torsion bar 07 is continued to be rotated until the small pipe fittings are clamped, and then the construction personnel can perform the polishing operation on the small pipe fittings using the existing polishing tools. By using the device described in the utility model, the polishing efficiency of small pipe fittings can be improved, and at the same time, the work quality of polishing small pipe fittings can be improved, and it has good applicability.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
