In the transmission line engineering, it plays a crucial role as a component connecting the foundation and the tower. The traditional anchor bolt installation method relies on manual measurement and adjustment, which has the problems of low efficiency, poor accuracy and high labor intensity. INVENTION CONTENTS

[0003] The utility model intends to provide a transmission line tower foundation anchor bolt adjustable auxiliary positioning device to solve the problems of low installation efficiency and poor accuracy of the anchor bolt in the prior art.

[0004] The transmission line tower foundation anchor bolt adjustable auxiliary positioning device in the scheme comprises a fixing frame, a positioning plate and a level detector, the positioning plate is provided with a positioning hole matched with the position and size of the anchor bolt; a plurality of supporting legs for lifting adjustment are arranged around the fixing frame, an installation opening is formed in the fixing frame, the positioning plate is detachably connected in the installation opening and coplanar with the fixing frame, and the level detector is installed on the positioning plate or the fixing frame.

[0005] The working principle of the scheme is that the core of the device is the cooperative work of the fixing frame, the positioning plate and the level detector. The fixing frame is lifted and adjusted through the plurality of supporting legs arranged around, so that the device can adapt to the installation requirements of different heights. The positioning plate is detachably connected in the installation opening of the fixing frame and coplanar with the fixing frame, so as to ensure the positioning accuracy of the anchor bolt. The level detector monitors the horizontal state of the positioning plate or the fixing frame in real time, so as to ensure that the whole device remains horizontal during the installation process. Through the lifting adjustment of the fixing frame and the feedback of the level detector, the positioning plate can accurately adjust the position, so as to ensure that the installation position of the anchor bolt is accurate.

[0006] The beneficial technical effects of the scheme are that through the cooperative work of the fixing frame, the positioning plate and the level detector, the device can realize the rapid and accurate installation of the anchor bolt, and solve the problems of low efficiency, poor accuracy and high labor intensity of the traditional manual measurement and adjustment method.

[0007] Further, a plurality of threaded holes are arranged on the fixing frame, a first screw rod is connected in the threaded hole, and a fixing groove corresponding to the first screw rod is arranged on the side wall of the positioning plate. After the first screw rod is screwed into the threaded hole, the end of the first screw rod is embedded in the fixing groove of the positioning plate, and the position of the positioning plate can be finely adjusted by rotating the first screw rod, so that the positioning plate is kept coplanar with the fixing frame. This design allows the positioning plate to be finely adjusted during installation, ensuring the positioning accuracy of the anchor bolt. Through the cooperation of the threaded hole, the fixing groove and the first screw rod, the position adjustment of the positioning plate is more precise and stable, further improving the accuracy and stability of the anchor bolt installation.

[0008] Further, a plurality of threaded holes are arranged on the fixing frame, a first screw rod is connected in the threaded hole, and a fixing groove corresponding to the first screw rod is arranged on the side wall of the positioning plate. After the first screw rod is screwed into the threaded hole, the end of the first screw rod is embedded in the fixing groove of the positioning plate, and the position of the positioning plate can be finely adjusted by rotating the first screw rod, so that the positioning plate is kept coplanar with the fixing frame. This design allows the positioning plate to be finely adjusted during installation, ensuring the positioning accuracy of the anchor bolt. Through the cooperation of the threaded hole, the fixing groove and the first screw rod, the position adjustment of the positioning plate is more precise and stable, further improving the accuracy and stability of the anchor bolt installation.

[0009] Further, the support leg comprises a coaxial support pipe and a second screw rod, a threaded segment is arranged on the inner wall of the support pipe, the second screw rod penetrates the bottom of the support pipe and is threadedly connected with the threaded segment, and the support pipe is connected with the fixing frame. By rotating the second screw rod, the height of the support leg can be adjusted, so that the levelness of the fixing frame is adjusted. The cooperation of the support pipe and the second screw rod makes the height adjustment more convenient and accurate.

[0010] Further, the threaded segment is located in the middle part of the support pipe. The threaded segment is located in the middle part of the support pipe, which means that the both ends of the support pipe inside are not threaded. When the second screw rod is screwed into the support pipe, the screw rod will first directly extend into the non-threaded segment of the support pipe without screwing operation, and the screwing connection will not start until the screw rod contacts the threaded segment. This design reduces the frequency of screwing operation, making the height adjustment more convenient and efficient, and reducing the labor intensity of workers.

[0011] Further, the top of the second screw rod penetrates the top of the support pipe, and a handle is arranged on the top of the second screw rod. Through the handle, the operator can conveniently rotate the second screw rod for height adjustment. The connection mode of the handle and the second screw rod makes the operation more convenient and fast.

[0012] Further, the handle is a stainless steel pipe bent into a ring-shaped handle, and the ring-shaped handle is fixedly connected with the top of the second screw rod, or the top of the second screw rod is spline-connected with the inner wall of a sleeve through the sleeve connected in the middle part of the ring-shaped handle. The design of the ring-shaped handle makes the operation more comfortable and convenient, and the spline connection enhances the connection stability of the handle and the second screw rod, preventing the handle from falling off due to improper operation.

[0013] Further, the handle is a straight handle, one end of the straight handle or the middle of the straight handle is fixedly connected with the top of the second screw rod, or the top of the second screw rod is connected with the inner wall of the sleeve through a sleeve connected at one end of the straight handle or the middle of the straight handle.

[0014] Further, the adjacent support pipes are connected with K-shaped reinforcing supports. By arranging the reinforcing supports at the corners between the support legs and the fixing frame, a rigid support structure is formed, which can effectively disperse the stress between the support legs and the fixing frame, prevent deformation or fracture caused by uneven stress or external impact, significantly enhance the stability and durability of the device, and help ensure the accuracy and efficiency of the anchor bolt installation.
