[0022] Reference Figure 1-Figure 3 A tower crane attached adjustable cylindrical clamp device includes a side bracket 1 and an adjusting pad 104. The inner wall of the side bracket 1 is provided with a clamping groove 101, and a plurality of clamping grooves 102 are provided inside the clamping groove 101. A regulating valve 105 is provided in the middle of the clamping groove 102. The regulating valve 105 passes through the clamping groove 101 and is threadedly connected to the side bracket 1. The regulating valve 105 is located in the clamping groove 102 in the middle of the clamping groove 101. One end of the regulating valve 105 is fixedly connected to the adjusting pad 104, and the adjusting pad 104 is movably connected to the inside of the side bracket 1 through the regulating valve 105.

[0023] When in use, the staff opens the clamping device, the side clamping frame 1 and the side clamping frame 3 are engaged on the column, and the regulating valve 105 is rotated according to the diameter of the column. The regulating valve 105 drives the adjusting pad 104 to move in the side clamping frame 1. If the diameter of the column is smaller than the inner diameter of the clamping device, the regulating valve 105 drives the adjusting pad 104 to move out of the engaging groove 101 and rest against the outside of the column. If the inner diameter of the column matches that of the clamping device, the adjusting pad 104 moves to the inside of the engaging groove 101, which facilitates the installation of the clamping device on the column.

[0024] In this embodiment, a spring 103 is provided on one side of the outer portion of the rod of the regulating valve 105 . One end of the spring 103 is fixedly connected to the inside of the clamping groove 102 , and the other end of the spring 103 is installed on the regulating pad 104 .

[0025] When in use, the adjusting pad 104 is limited by the spring 103 to facilitate the adjustment pad 104 to move its position, and at the same time, the spring 103 assists the regulating valve 105 to support the adjusting pad 104 .

[0026] In this embodiment, the spring 103 and the regulating valve 105 are both located on the same curved surface of the regulating pad 104 . A side clamp frame 3 is provided on the side of the regulating pad 104 away from the regulating valve 105 . The side clamp frame 3 has the same structure as the side bracket 1 .

[0027] When in use, the adjustment pad 104 is arc-shaped, so that the inner wall of the adjustment pad 104 matches the outer surface of the column, and at the same time it is convenient for the adjustment pad 104 to shrink into the inner wall snap-fitting groove 101 of the side bracket 1.

[0028] In this embodiment, one end of the side hoop frame 3 is snap-fitted to the side holding frame 1 , and a retaining bolt 2 is installed at one end of the side holding frame 1 close to the side hoop frame 3 , and both ends of the retaining bolt 2 are connected to the side hoop frame 3 .

[0029] When in use, the clamp device is divided into a side clamp frame 1 and a side clamp frame 3. When the clamp device is opened, the side clamp frame 1 and the side clamp frame 3 are movable and opened with the retaining bolt 2 as the center, so that the staff can install the clamp device conveniently and take it conveniently to avoid the structure dispersion affecting the installation.

[0030] In this embodiment, the side hoop frame 3 is movably connected to the side holding frame 1 via the retaining bolt 2 , and a plurality of extension edges 4 are installed at the top and bottom of the side hoop frame 3 and the side holding frame 1 .

[0031] When in use, other structures of the tower crane can be fixedly connected through the plug-in hole 5 on the extension 4. The extension 4 not only does not affect the connection between the clamp device and the tower crane, but also protects the regulating valve 105 to prevent falling objects from high altitude from hitting the regulating valve 105, causing the regulating valve 105 to deform and affect the use of the regulating pad 104.

[0032] In this embodiment, a plurality of plug holes 5 are provided on the top of the extension 4 , a regulating valve 105 is provided between the extensions 4 , and an ear seat 6 is installed on the side of the side bracket 1 and the side clamp frame 3 away from the retaining bolt 2 .

[0033] When in use, the side holding frame 1 is fixedly connected to the side hoop frame 3 by bolts penetrating the ear seat 6 to close the opening of the hoop device.

[0034] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: the clamp device is divided into a side clamp frame 1 and a side clamp frame 3. When the clamp device is opened, the side clamp frame 1 and the side clamp frame 3 are movable and opened with the retaining bolt 2 as the center, which is convenient for the staff to install the clamp device and convenient for the staff to take it to avoid the structure dispersion affecting the installation. The staff opens the clamp device, and the side clamp frame 1 and the side clamp frame 3 are clamped on the column. The regulating valve 105 is rotated according to the diameter of the column. The regulating valve 105 drives the adjusting pad 104 to move in the side clamp frame 1. If the diameter of the column is smaller than the inner diameter of the clamp device, the regulating valve 105 drives the adjusting pad 104 to move out of the clamping groove 101 and against the outside of the column. If the column and the inner diameter of the clamp device match, the adjusting pad 104 moves to the inside of the clamping groove 101, which is convenient for the clamp device to be installed on the column.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
