Technical Field

[0001] This utility model relates to the field of thermal insulation pipe processing technology, and in particular to a clamping device for processing composite thermal insulation pipes. Background Technology

[0002] Thermal insulation pipe is short for heat-insulated pipeline. It is used for transporting liquids, gases, and other media, and is used in thermal insulation projects for pipelines in industries such as petroleum, chemical, aerospace, hot springs, district heating, central air conditioning, and municipal engineering. Thermal insulation pipe is suitable for transporting various media within a temperature range of -50°C to 150°C. It is widely used in district heating, cooling, and hot oil transportation, as well as in insulation and cold storage projects in industries such as greenhouses, cold storage facilities, coal mines, petroleum, and chemical plants.

Multiple positioning arc rings are spaced apart to form a ring. The positioning arc rings are connected to the mounting arc seat on the side near the limiting mechanism. The upper end of the mounting arc seat has several mounting bolt holes, and positioning bolts are installed in the mounting bolt holes. The positioning bolts pass through the mounting bolt holes to fix the mounting arc seat to the device base. A movable groove is opened in the middle of the end face of the mounting arc seat. Fixed shafts are fixedly installed in the middle of the left and right end faces of the clamping component. The fixed shafts are correspondingly set with the movable grooves, and the clamping component can rotate around the fixed shafts.

[0007] In a preferred embodiment: the device base includes an annular base, a circular inner groove and a fixing groove. The annular base is fixedly installed at the center of the bottom of the device base plate. The circular inner groove is opened at the center of the upper end of the annular base. The circular inner groove is used for the placement of the reset spring and the reception of the pressure ring. The fixing groove is opened at the center of the bottom of the annular base. The fixing groove is used for the insertion of the fixing seat.

[0008] In a preferred embodiment: the limiting mechanism includes a fixed seat, a fixed bolt, an internally threaded sleeve, a screw, a nut sleeve, a pressure ring, an annular groove, a return spring, a long gear, a limiting component, meshing teeth, and a drive rod. The internally threaded sleeve is fixedly installed in the middle of the fixed seat. A meshing screw is provided inside the internally threaded sleeve. A pressure ring is sleeved on the outside of the internally threaded sleeve. An annular groove is formed on the side end face of the pressure ring. A return spring is fixedly installed between the bottom of the pressure ring and the bottom surface of the circular inner groove. A nut sleeve is sleeved on the top of the screw. The nut sleeve is used to prevent the pressure ring from slipping out of the limiting position on the internally threaded sleeve.

Meshing teeth are provided below the long gear, and a drive rod is fixedly installed in the middle of the meshing teeth.

[0011] In a preferred embodiment: a T-shaped component is fixedly installed at one end of the clamping member near the limiting mechanism, and the T-shaped component is movably disposed within the annular groove.

[0012] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0013] 1. When this utility model is in use, the external control motor drives the drive rod to rotate, and the meshing teeth will mesh with the long gear. The long gear will simultaneously drive the screw to rotate, and the screw will mesh with the internal thread sleeve. Since the internal thread sleeve is fixed to the annular base by the fixed seat and the fixing bolt, the screw will drive the nut sleeve to move towards the long gear. The return spring will contract, and the nut sleeve will push the pressure ring to slide synchronously. At this time, the pressure ring will push the T-shaped part in the annular groove, and the clamping part will rotate around the fixed shaft. It can provide good clamping force for processing composite insulation pipes of different diameters and increase the practical effect of the clamping equipment. Attached Figure Description

[0026] The device base 2 includes an annular base 21, a circular inner groove 22, and a fixing groove 23. The annular base 21 is fixedly installed in the center of the bottom of the device base plate 1. The circular inner groove 22 is opened in the middle of the upper end of the annular base 21. The circular inner groove 22 is used for the placement of the reset spring 38 and the accommodation of the pressure ring 36. The fixing groove 23 is opened in the center of the bottom of the annular base 21. The fixing groove 23 is used for the insertion of the fixing seat 31.

[0027] The limiting mechanism 3 includes a fixed base 31, a fixing bolt 32, an internally threaded sleeve 33, a screw 34, a nut sleeve 35, a pressure ring 36, an annular groove 37, a return spring 38, a long gear 39, a limiting component 310, a meshing gear 311, and a drive rod 312. The internally threaded sleeve 33 is fixedly installed in the middle of the fixed base 31, and the meshing screw 34 is provided inside the internally threaded sleeve 33. A hole is opened along the bottom edge of the fixed base 31, and a fixing bolt 32 is provided inside the hole. The fixed base 31 is mounted on the annular base 21 via the fixing bolt 32. The long gear 39 is fixedly installed at the lower end of the screw 34. Both ends of the wheel 39 are equipped with limiters 310 to prevent the long gear 39 from slipping and disengaging when it is engaged with the meshing teeth 311. A pressure ring 36 is fitted on the outside of the internal threaded sleeve 33. A ring groove 37 is opened on the side end face of the pressure ring 36. A return spring 38 is fixedly installed between the bottom of the pressure ring 36 and the bottom surface of the circular inner groove 22. A nut sleeve 35 is fitted on the top of the screw 34. The nut sleeve 35 is used to prevent the pressure ring 36 from slipping out of the limit on the internal threaded sleeve 33. A meshing tooth 311 is provided below the long gear 39. A drive rod 312 is fixedly installed in the middle of the meshing tooth 311.

Multiple positioning arc rings 41 are spaced apart and arranged in a ring. The positioning arc rings 41 are connected to the mounting arc seat 42 on the side near the limiting mechanism 3. Several mounting bolt holes 43 are provided at the upper end of the mounting arc seat 42. Positioning bolts 44 are installed in the mounting bolt holes 43, passing through the mounting bolt holes 43 to fix the mounting arc seat 42 onto the device base 2.

A T-shaped member 47 is fixedly installed at the end of the clamping member 46 near the limiting mechanism 3. The T-shaped member 47 is movably set in the annular groove 37. Thus, the axial sliding of the annular groove 37 on the internal threaded sleeve 33 drives the clamping member 46 to rotate, providing a good clamping force for the processing of composite insulation pipes.

[0029] The working principle of this utility model is as follows:

[0030] When this utility model is used, the composite insulation pipe is placed in the positioning arc ring 41. The external control motor drives the drive rod 312 to rotate, and the meshing teeth 311 will mesh with the long gear 39. The long gear 39 simultaneously drives the screw 34 to rotate, and the screw 34 meshes with the internal thread sleeve 33. Since the internal thread sleeve 33 is fixed on the annular base 21 by the fixing seat 31 and the fixing bolt 32, the screw 34 will drive the nut sleeve 35 to move towards the long gear 39. The return spring 38 retracts, and the nut sleeve 35 pushes the pressure ring 36 to slide synchronously. At this time, the pressure ring 36 will push the T-shaped piece 47 in the annular groove 37, and the clamping piece 46 will rotate around the fixed shaft 48. This can provide good clamping force for the processing of composite insulation pipes of different diameters and increase the practical effect of the clamping equipment.

[0031] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
