DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-10 , a specific implementation of the utility model is:

[0032] like Figure 1-4 As shown, a snap-on locking foot anchor rod orientation device is composed of a fixed bracket 1 and a guide frame 2. The fixed bracket 1 is a snap-on structure and can be fixed on tunnel invert I-beams of different sizes. The fixed bracket 1 and the guide frame 2 are connected by a spherical device, so that the guide frame 2 can rotate around the connection node, thereby freely adjusting the deflection angle and fixing it, providing accurate orientation for the locking foot anchor rod and reducing the construction error of the locking foot anchor rod.

[0033] like Figure 5-7 As shown, the basis of the fixed bracket 1 is the first oriented plate 101, and the first oriented plate 101 is a rectangular plate, one side of which is provided with a fixed snap plate 102 perpendicular to the first oriented plate 101, and the other side is provided with two telescopic rods 104, the outer end of the telescopic rod 104 is connected with an active snap plate 103 perpendicular to the first oriented plate 101, and a high-strength spring is provided inside the telescopic rod 104. When the spring is naturally contracted, the telescopic rod 104 is retracted to the inside of the first oriented plate 101, and the active snap plate 103 is pulled open by external force to extend the telescopic rod 104, and the fixed bracket 1 is placed on the I-beam so that the first oriented plate 101 is close to the I-beam flange plate, and the active snap plate 103 is loosened to allow the telescopic rod 104 to be retracted under the action of the spring, and the fixed bracket 1 can be automatically snapped onto the I-beam. A fixing bolt 105 is provided at the end of the first directional plate 101, and its bolt hole is parallel to the telescopic rod 104 and passes through the movable snap plate 103. After the fixed bracket 1 is snapped on the I-beam, the fixing bolt 105 is installed to fix the movable snap plate 103 and the first directional plate 101 to prevent the telescopic rod 104 from extending and causing the fixed bracket 1 to fall off. A first support rod 106 is vertically provided on the first directional plate 101, and a ball seat 107 is provided on the first support rod 106. Four directional rods 108 perpendicular to the first directional plate 101 are provided at the four corners of the first directional plate 101.

[0034] like Figure 8 As shown, a directional slot 109 is provided on the directional rod 108, and a locking rod 110 is provided in the directional slot 109. The locking rod 110 is connected to the directional rod 108 through a clamping plate 111, and a clamping plate bolt 112 is provided on the clamping plate 111. When the clamping plate bolt 112 is loosened, the locking rod 110 can slide along the directional slot 109. Tightening the clamping plate bolt 112 will cause the clamping plate 111 to clamp the directional rod 108, thereby fixing the locking rod 110.

[0035] like Figure 9-10As shown, the base of the guide frame 2 is a rectangular second directional plate 201, and a second support rod 205 is provided on one side of the second directional plate 201. A ball head 206 is provided on the second support rod 205. The ball head 206 can be connected to the ball seat 107 and rotated within a certain angle, so that the second directional plate 201 is deflected relative to the first directional plate 101. Two directional support plates 202 are arranged in parallel on both sides of the second directional plate 201. The directional support plates 202 are provided with circular directional holes 204, and the two directional holes 204 are located at the same height. Four movable grooves 203 are provided in the four corner directions of the second directional plate 201. The center position of the movable groove 203 matches the directional rod 108. The size of the movable groove 203 is larger than the cross-sectional size of the directional rod 108, so that the directional rod 108 can be tilted at a certain angle in the movable groove 203. The locking rod 110 is always above the second directional plate 201. When the second directional plate 201 adjusts its angle, the clamping plate 111 is in a relaxed state. The locking rod 110 slides freely following the deflection of the second directional plate 201. When the second directional plate 201 deflects to the correct position, the clamping plate bolts 112 are tightened to fix the four locking rods 110. The second directional plate 201 cannot deflect further, and the orientation of the directional hole 204 is fixed. The locking foot anchor rod is passed through the two directional holes 204 in sequence and then fixed to ensure that the direction of the anchor rod remains unchanged during the construction process.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
