[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0029] like Figures 1 to 5As shown, an anchor plate positioning tool comprises a jacking device 10 and a lifting frame fixed on the jacking end of the jacking device 10; the lifting frame comprises a base frame, an anchor plate bracket hinged on the front end of the base frame and a diagonal brace assembly obliquely arranged at the rear end of the lifting frame, the anchor plate bracket is inclined, the length of the diagonal brace assembly is adjustable, the top end of the diagonal brace assembly is pressed against the middle and upper part of the rear side surface of the anchor plate bracket, that is, the rear side of the anchor plate bracket abuts against the top end of the diagonal brace assembly, thereby forming a triangular structure between the anchor plate bracket, the diagonal brace assembly and the base frame, which can provide stable support for the rear anchor plate during construction; the length of the diagonal brace assembly is adjustable, and the angle of the anchor plate bracket is adjustable, so as to adapt to the installation of the rear anchor plate on the installation surface with different angles. The anchor plate bracket includes a support plate 4 hinged on both sides of the front end of the base frame and a bottom bracket 6 arranged at the bottom of the front side of the support plate 4; the bottom bracket 6 is made of angle steel and is used to support the rear anchor pad from the bottom; the two support plates 4 are connected to the same bottom bracket 6; the cross-section of the support plate 4 is L-shaped, rectangular or I-shaped, that is, the support plate 4 can be angle steel, square steel or I-beam.

[0030] like Figures 1 to 3 As shown, the lifting frame includes a main beam 1, a front beam 2 arranged at the front end of the main beam 1 and a rear beam 12 arranged at the rear end of the main beam 1; the front beam 2 is parallel to the rear beam 12, and a plurality of fixing holes 11 are opened on the main beam 1; the jacking equipment 10 adopts the horizontal jack in the prior art, and its pallet is modified, such as fixing studs on its pallet, and then the main beam 1 is installed on the pallet of the horizontal jack, the studs are aligned with the fixing holes 11, and then the main beam 1 is fixed with nuts; mounting plates 3 are vertically arranged on both sides of the front beam 2, and the lower end of the inner side of the support plate 4 is hinged on the mounting plate 3; preferably, the main beam 2 is made of U-shaped steel.

[0031] The rear anchor pad is round, optional, such as Figures 1 to 3 As shown, an upper support 5 is fixed to the inner side of the top end of each support plate 4, and the two upper supports 5 extend relative to each other so as to support the rear side of the top arc portion of the rear anchor plate.

[0032] Preferably, Figure 1 As shown, the inner side surface of the support plate 4 is relatively provided with a plurality of groups of rebar insertion holes 15; for example, 2-4 groups of rebar insertion holes 15 can be provided, and rebars can be inserted into the rebar insertion holes 15 so that the rebars are horizontally arranged between the two support plates 4, thereby effectively supporting the rear anchor plate with a smaller diameter.

[0033] Further, such as Figures 1 to 5As shown, the diagonal brace assembly includes a cylinder seat 7 fixed on both sides of the lifting frame, a screw rod 9 placed in the cylinder seat 7, and a buckle 8 arranged in the middle of the screw rod 9, the circumscribed circle diameter of the buckle 8 is larger than the outer diameter of the cylinder seat 7, and the buckle 8 covers the top opening of the cylinder seat 7; the length of the part of the screw rod 9 and the cylinder seat 7 exposed from the cylinder seat 7 is the effective length of the support anchor plate bracket, and the buckle 8 is adjusted as needed by screwing the buckle 8 on the screw rod 9 to adjust the length of the diagonal brace assembly; the inner diameter of the cylinder seat 7 is more than 1.5 times the outer diameter of the screw rod 9, so that the screw rod 9 can adjust its position in the cylinder seat 7; after the inclination angle of the anchor plate bracket is adjusted, the position of the screw rod 9 in the cylinder seat 7 can be adjusted automatically to avoid motion interference.

[0034] The top end of the screw rod 9 is directly connected to the support plate 4 by contact, hinge or welding. A plug is arranged on the top end of the screw rod 9 , and the plug is connected to the support plate 4 by contact, hinge or welding.

[0035] In one embodiment, the top is a U-shaped bracket 13, which is fixedly connected to the rear side of the support plate 4; the U-shaped bracket 13 is vertically arranged, and both ends of the U-shaped bracket 13 are welded and fixed to the support plate 4 or only the lower end / lower edge is welded and fixed to the anchor plate. Figure 4 As shown, when only the lower end / lower edge of the U-shaped bracket 13 is fixedly connected to the support plate 4, the middle part of the U-shaped bracket 13 can be bent when adjusting the inclination angle of the anchor plate bracket, thereby increasing the adjustment range of the inclination angle of the anchor plate bracket; at the same time, since it is not directly connected to the support plate 4, there is no need to worry about the anchor plate bracket tipping forward. In addition to self-processing, the screw rod 9, the buckle 8 and the U-shaped bracket 13 can also directly use commercially available building top support screws.

[0036] Optional, such as Figure 5 As shown, the top end of the screw rod 9 is threadedly connected with a cap nut 14; when the cap nut 14 is used, the top end of the screw rod 9 and the support plate 4 pass through the top end of the cap nut 14. Although this arrangement does not need to consider the problem of motion interference when adjusting the angle, it is necessary to prevent the anchor plate bracket from tipping forward during use.

[0037] When the utility model is used in an anchor chamber, a temporary construction platform is first built at the construction location, and then the device is placed on the construction platform, the angle of the anchor plate bracket is roughly adjusted, the rear anchor plate is placed on the anchor plate bracket, and lifted to the installation position by a jacking device; thereafter, the angle of the anchor plate bracket is fine-tuned by screwing the disc buckle 8 according to the inclination angle of the installation surface in the anchor chamber until the rear anchor plate fits with the installation surface, and the rear anchor plate is fixed.

[0038] The utility model has an anchor plate bracket with adjustable inclination, which can lift the rear anchor plate and fit it to installation surfaces with different angles, and has a wide application angle. When installing the rear anchor plate on installation surfaces with different angles, it does not need to be replaced, which is convenient for workers to construct.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
