The personnel need to use tools for reference measurement many times, and the work efficiency is low. Utility Model Content

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: Figures 1-4As shown, the utility model provides a port trimming device for a directly buried insulated pipe, comprising: a frame 1, a mounting frame 2 is fixedly connected to the rear surface of the frame 1, a first motor 3 is fixedly connected to the rear surface of the mounting frame 2, an output end of the first motor 3 rotates and passes through the outer surface of the mounting frame 2, and an output end of the first motor 3 is fixedly connected to a threaded rod 4, which is rotatably connected to the frame 1; a friction assembly 5, the friction assembly 5 is arranged on the rear surface of the frame 1, the friction assembly 5 includes a mounting plate 501, a plurality of first connecting blocks 502 are equidistantly fixedly connected to the rear surface of the mounting plate 501, an inner surface of one of the first connecting blocks 502 is threadedly rotatably connected to the outer surface of the threaded rod 4; a fixing assembly 7, the fixing assembly 7 is fixedly connected to the inner bottom of the frame 1, the fixing assembly 7 includes a base 701, and the top of the base 701 is fixedly connected to The first arc block 702 is fixedly connected to the second motor 503 at the center of the rear surface of the mounting plate 501, and the output end of the second motor 503 rotates and passes through the rear surface of the mounting plate 501. The output end of the second motor 503 is fixedly connected to the turntable 504, and the front surface of the turntable 504 is provided with a friction block 505. The top of the first arc block 702 is provided with a second arc block 703, and the outer surface of the second arc block 703 is symmetrically fixedly connected with the second connecting block 704. The base 701 is fixedly connected to the inner bottom of the frame 1, and the top of the base 701 is symmetrically fixedly connected with a fixing rod 705, which is movably penetrated by the second connecting block 704. The tops of the two second connecting blocks 704 are both provided with internal thread blocks 706, and the inner surfaces of the two internal thread blocks 706 are respectively threaded and rotatably connected with the outer surfaces of the two fixing rods 705.

[0023] The effect achieved by the entire embodiment 1 is that, when the port of the directly buried thermal insulation pipe is trimmed, a base 701 is provided at the inner bottom of the frame 1, and a first arc block 702 is fixedly connected to the top thereof, so that personnel can place the directly buried thermal insulation pipe in its arc surface so that it is between the first arc block 702 and the second arc block 703. The port to be friction-trimmed and the friction surface of the friction block 505 are perpendicular to each other. Personnel can support or rotate the two internal thread blocks 706 in sequence so that when the outer surface threads of the corresponding fixed rod 705 move downward, the two internal thread blocks 706 will tightly contact the two second connecting blocks 704, driving the second arc block 703 to closely fit the surface of the directly buried thermal insulation pipe to be processed. It is clamped and fixed between two arc-shaped blocks, and the first motor 3 set on the rear surface of the mounting frame 2 is started. When the output end of the first motor 3 drives the threaded rod 4 to rotate forward in the inner wall of the frame 1, one of the first connecting blocks 502 threadedly connected thereto will drive the mounting plate 501 to move forward, and the second motor 503 is started synchronously. The output end of the second motor 503 drives the turntable 504 to rotate at high speed, so that the synchronously rotating friction block 505 will maintain a vertical direction to rub and trim the port surface of the directly buried thermal insulation pipe when it gradually contacts the port of the directly buried thermal insulation pipe, so that the burrs or protrusions on the port surface are removed until the surface is smooth and vertical, and the grinding and trimming speed is fast, thereby improving the trimming efficiency of the directly buried thermal insulation pipe.

[0024] Example 2: Figures 1-4 As shown, the rear surface of the rack 1 near the bottom is symmetrically fixedly connected with the sliding rods 6, and the inner surfaces of the other two first connecting blocks 502 are slidably connected to the outer surfaces of the two sliding rods 6 respectively.

[0025] The effect achieved by the entire embodiment 2 is that, when in use, by symmetrically fixing the connecting slide bars 6 on the rear surface of the frame 1, when the first motor 3 drives the mounting plate 501 to move forward, the other two first connecting blocks 502 fixedly connected to its surface slide synchronously on the outer surfaces of the two slide bars 6, playing a limiting role, preventing the position from being offset during displacement, and having high practicality.

[0026] Working principle: When trimming the port of the directly buried insulated pipe, a base 701 is set at the inner bottom of the frame 1, and a first arc block 702 is fixedly connected to the top thereof, so that personnel can place the directly buried insulated pipe in its arc surface so that it is between the first arc block 702 and the second arc block 703. The port to be friction-trimmed and the friction surface of the friction block 505 are perpendicular to each other. Personnel can support or rotate the two internal thread blocks 706 in sequence so that when the outer surface threads of the corresponding fixed rod 705 move downward, the two internal thread blocks 706 will tightly contact the two second connecting blocks 704, driving the second arc block 703 to fit closely to the surface of the directly buried insulated pipe to be processed, so that it is clamped and fixed between the two arc blocks, and start the first motor 3 set on the rear surface of the mounting frame 2. The output end of the first motor 3 drives the threaded rod When the inner wall of the frame 1 rotates forward, one of the first connecting blocks 502 threadedly connected thereto drives the mounting plate 501 to move forward, and the second motor 503 is started synchronously. The output end of the second motor 503 drives the turntable 504 to rotate at a high speed, so that the synchronously rotating friction block 505 gradually contacts the port of the directly buried thermal insulation pipe, and maintains a vertical friction trimming direction on the port surface to remove burrs or protrusions on the port surface until the surface is smooth and vertical, and the grinding and trimming speed is fast. By symmetrically fixing the slide bars 6 on the rear surface of the frame 1, when the first motor 3 drives the mounting plate 501 to move forward, the other two first connecting blocks 502 fixedly connected to its surface slide synchronously on the outer surfaces of the two slide bars 6, which plays a role of limiting and preventing its position from shifting during displacement, and has high practicality.
