They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model is a municipal inspection wellhead suspension template device. Its structure mainly includes a support frame 1, an adjustable suspension mechanism 2, and an adjustable wellhead template 3. The adjustable wellhead template 3 is suspended below the support frame 1 through the adjustable suspension mechanism 2.

[0021] like Figure 4 As shown, the adjustable wellhead template 3 is made of a flexible sheet material. After bending and closing, the adjustable wellhead template 3 forms a circle. To allow for size adjustment, adjustment holes 3-1 are provided at both ends of the adjustable wellhead template 3, with the holes 3-1 corresponding to each other. Fastening bolts 3-2 are inserted into the adjustment holes 3-1. The size of the adjustable wellhead template 3 is adjusted by moving the relative positions of its two ends. After adjusting the size, the fastening bolts 3-2 are tightened to fix the two ends of the adjustable wellhead template 3 together.

[0022] To prevent deformation of the adjustable wellhead template 3 during use, two adjustable inner support rods 4 are installed inside the template 3. These two inner support rods 4 are arranged in a cross shape, and are staggered vertically. The two ends of the adjustable inner support rods 4 support the inner wall of the adjustable wellhead template 3, thereby preventing deformation of the circular adjustable wellhead template 3 during use and ensuring the shape accuracy of the concrete wellhead.

[0023] Since the adjustable wellhead template 3 can be adjusted in size, the end of the adjustable inner support rod 4 is movably connected to the inner wall of the adjustable wellhead template 3 to accommodate adjustments. Specifically, a plug-in sleeve 5 can be installed on the inner wall of the adjustable wellhead template 3. The plug-in sleeve 5 is welded to the inner wall of the adjustable wellhead template 3, and its axis is perpendicular to the inner wall of the adjustable wellhead template 3. The end of the adjustable inner support rod 4 is inserted into the plug-in sleeve 5, and the inner diameter of the plug-in sleeve 5 is larger than the diameter of the end of the adjustable inner support rod 4, so that there is a certain amount of movement between the end of the adjustable inner support rod 4 and the inner wall of the plug-in sleeve 5 to accommodate changes in the angle between the adjustable inner support rod 4 and the inner wall of the adjustable wellhead template 3 when the size of the adjustable wellhead template 3 changes. Alternatively, the end of the adjustable inner support rod 4 can be connected to the inner wall of the adjustable wellhead template 3 by a hinge.

[0024] There are four plug-in sleeves 5, and the four plug-in sleeves 5 are roughly evenly distributed along the inner wall of the adjustable wellhead template 3.

[0025] The adjustment hole 3-1 is specifically a long strip hole, and each end of the adjustable wellhead template 3 is provided with two or more long strip holes.

[0026] The adjustable inner support rod 4 can adjust its length to provide stable support for adjustable wellhead templates 3 of different sizes. Specifically, the adjustable inner support rod 4 includes a threaded rod 4-1 and threaded sleeves 4-2 threadedly connected to both ends of the threaded rod 4-1. By rotating the threaded rod 4-1 and the threaded sleeves 4-2 relative to each other, the threaded sleeves 4-2 at both ends can be extended or retracted, thereby adjusting the length of the adjustable inner support rod 4.

[0027] The adjustable suspension mechanism 2 specifically includes a connecting rope 2-1, a turnbuckle 2-2, and a sling 2-3. The upper end of the turnbuckle 2-2 is connected to the support frame 1 via the connecting rope 2-1, and the lower end of the turnbuckle 2-2 is connected to the adjustable wellhead template 3 via the sling 2-3. The sling 2-3 is connected to the inner wall or top of the adjustable wellhead template 3, or it can be connected to the aforementioned plug-in sleeve 5. For example, a lifting ring is provided on the plug-in sleeve 5, and the lower end of the sling 2-3 is connected to the lifting ring.

[0028] The adjustable suspension mechanism 2 can also be an electric hoist or a hand-operated hoist, or other device that can adjust the suspension height.

[0029] The support frame 1 specifically includes legs 1-1 and a top frame 1-2. The top frame 1-2 has a rectangular structure. There are four legs 1-1, which are respectively located at the lower corners of the top frame 1-2. The support of the legs 1-1 provides the top frame 1-2 with a certain height so as to install the adjustable suspension mechanism 2 and suspend the adjustable wellhead template 3. Both the legs 1-1 and the top frame 1-2 are assembled from channel steel and other structural steel.

[0030] There are four adjustable suspension mechanisms 2, which are distributed in pairs on the two crossbeams of the top frame 1-2. The positions of the four adjustable suspension mechanisms 2 roughly correspond to the positions of the four connection points on the adjustable wellhead template 3.

[0031] The method of using this utility model is as follows: When constructing a municipal road manhole, firstly, adjust the size of the adjustable manhole template 3 according to the size of the manhole opening, and install two adjustable inner support rods 4 on the inner wall of the adjustable manhole template 3 for support to prevent deformation; then, erect the support frame 1 above the manhole, adjust the position of the support frame 1, and suspend the adjustable manhole template 3 to the manhole opening position through the adjustable suspension mechanism 2, with the lower end of the template inserted into the inner wall of the manhole; adjust the elevation and level of the adjustable manhole template 3 by adjusting each adjustable suspension mechanism 2, and after adjustment, pour concrete for the manhole opening on the outside of the template; repair the inner wall of the manhole; move to the next manhole position for manhole opening construction.
