[0002] In the installation of crane tracks and the construction of steel structure main workshops, channel steels with high support strength and long service life are often used as construction materials. Due to factors such as the long track length and the large workshop area, in order to minimize the impact of the channel steel connection points on the overall construction structure, extra-long channel steels are often used for construction to reduce the number of channel steel connection points, which also helps to ensure the construction quality and construction efficiency. Due to the influence of the material of the channel steel itself, expansion joints need to be processed at the connection points of the channel steel. At this time, part of the two wing plates at the end of the channel steel needs to be removed. Currently, when performing the above operations, especially at the beginning and end of cutting, due to the huge changes in the force on the channel steel, slippage is very likely to occur, which will also cause damage to the cutting edge, uneven cutting surface, insufficient cutting accuracy, etc., thereby affecting its effect during later use.

DETAILED DESCRIPTION

[0020] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the fixing device for cutting off the wing plate at the end of the extra-long channel steel is installed on the cutting table and can be used with at least one support frame for supporting and raising the extra-long channel steel 1, so as to keep the extra-long channel steel 1 in a horizontal state with the help of the support frame, thereby facilitating the smooth progress of the wing plate cutting operation. Specifically, it includes a support base plate 2, and other structures are installed on the support base plate 2. When in use, the support base plate 2 is placed on the cutting table, and when not in use, it is removed to free up the space on the cutting table for performing other cutting tasks, thereby ensuring the utilization rate of the cutting equipment. In order to facilitate the placement or removal of the support base plate 2, handles 3 can be installed at both ends of the support base plate 2 relative to each other, and the support base plate 2 can be carried by the cooperation of two people with the help of the handles 3.

[0022] Two cooperating clamping and fixing devices are mounted on the support base plate 2. A clamping gap is formed between the two clamping and fixing devices to accommodate the extra-long channel steel 1. By adjusting the size of the clamping gap, the extra-long channel steel 1 can be adapted to be cut and used with flanges of different widths, making it more flexible and versatile. Specifically, the clamping and fixing device includes at least two linearly arranged clamping support vertical plates 4. A clamping and fixing horizontal plate 5 is movably provided on the inner side of the clamping support vertical plates 4. Cooperating clamping and locking bolts 6 are threadedly installed through the corresponding clamping support vertical plates 4, and one end of each clamping and locking bolt 6 is respectively arranged corresponding to the side wall of the clamping and fixing horizontal plate 5. The size of the clamping gap is adjusted by moving the clamping and fixing horizontal plates 5 inward or outward. With the cooperation of the clamping and locking bolts 6, the two clamping and fixing horizontal plates 5 are fixed to the outer surface of the flange of the extra-long channel steel 1, thereby achieving a clamping and fixing effect on the extra-long channel steel 1.

[0023] In this embodiment, three clamping support vertical plates 4 are provided, and a horizontal plate push-pull rod 7 is movably inserted through the middle clamping support vertical plate 4. The end of the horizontal plate push-pull rod 7 is fixedly connected to the clamping fixed horizontal plate 5. When in use, the clamping fixed horizontal plate 5 can be pushed and pulled significantly by the horizontal plate push-pull rod 7. After the clamping fixed horizontal plate 5 contacts the wing plate of the extra-long channel steel 1, the clamping locking bolts 6 are rotated to tighten the clamping fixed horizontal plate 5 against the surface of the wing plate of the extra-long channel steel 1, making the clamping and fixing operation faster.

[0024] The side walls of the clamping and fixing horizontal plate 5 are provided with corresponding limiting screw sleeves 8 for use with each of the clamping and fixing bolts 6. The clamping and fixing bolts 6 are plugged into and matched with the corresponding limiting screw sleeves 8. The limiting screw sleeves 8 limit the clamping and fixing bolts 6, preventing the ends of the clamping and fixing bolts 6 from slipping, making the clamping and fixing operation smoother and the clamping and fixing effect better. In this embodiment, the ends of each of the clamping and fixing bolts 6 and the ends of the horizontal plate push-pull rods 7 are respectively provided with hand wheels 9 for easy operation to facilitate operation and improve operating efficiency.

[0025] This embodiment also includes a compression and fixing device used in conjunction with the two clamping and fixing devices to form a downward pressure and tightening effect on the extra-long channel steel 1, so as to cooperate with the clamping and fixing device to fix the extra-long channel steel 1 in three directions: left, right, and top. Specifically, the compression and fixing device includes a compression adjustment horizontal plate 10 that is arranged across the clamping gap, a compression vertical shaft 11 is fixedly installed at the bottom end of the compression adjustment horizontal plate 10, a compression plate 12 is fixedly connected to the bottom end of the compression vertical shaft 11, and two compression screws 13 are relatively provided through the compression adjustment horizontal plate 10, and each of the compression screws 13 is threadedly assembled with a compression nut 14 on both sides of the compression adjustment horizontal plate 10. By adjusting the two compression nuts 14, the height of the compression adjustment horizontal plate 10 can be adjusted to drive the compression vertical shaft 11 and the compression plate 12 to move downward synchronously until the compression plate 12 contacts the extra-long channel steel 1 and presses it.

[0026] The clamping screw 13 is fixedly connected to the supporting base plate 2. When cutting, only the extra-long channel steel 1 with a width smaller than the distance between the two clamping screws 13 can be cut. Of course, the clamping nut 14 can also be fixedly installed on the clamping fixed horizontal plate 5 on the corresponding side, and an adaptive long hole 15 is provided through the clamping adjustment horizontal plate 10 and each of the clamping nuts 14 for use. The corresponding clamping screw 13 can be driven to move synchronously by the clamping fixed horizontal plate 5, thereby adjusting the distance between the two clamping screws 13, so that the width restriction of the extra-long channel steel 1 when cutting the wing plate is reduced, further improving the flexibility of the use of this embodiment. The setting of the adaptive long hole 15 is designed to adapt to the adjustment of the position of the clamping screw 13.

[0027] The description of the present invention is provided for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
