DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: an anti-tipping positioning base for a long row of slab negative reinforcement support trestles, including a support base 1 and a cover plate 5. An adjustment component 2 is fixedly installed on the top of the support base 1, and a support platform 3 is fixedly installed on the top of the adjustment component 2. A slot 4 is movably installed on the top of the support platform 3, and a slot 4 is provided between the support platform 3 and the cover plate 5. The adjustment component 2 includes a lower support rod 21 and an upper support rod 22 arranged symmetrically on the left and right. A connecting rod 23 is movably hinged to the outer end of the lower support rod 21 and the upper support rod 22. A two-way screw 24 is movably installed inside the connecting rod 23. A fixed seat 1 is movably hinged to the inner end of the lower support rod 21, and a fixed seat 27 is movably hinged to the inner end of the upper support rod 22. 26 is fixedly installed on the top of support base 1, and fixed base 27 is fixedly installed on the bottom of support platform 3. By rotating the hexagonal head 25, the double-acting screw 24 inside the connecting rod 23 on both sides can be rotated. The connecting rod 23 and the double-acting screw 24 are connected by threads. The rotation of the double-acting screw 24 will cause the connecting rod 23 to slide relative to its outer side. When the connecting rod 23 slides inward, it will push the lower support rod 21 and the upper support rod 22 located between fixed base 1 26 and fixed base 27 to move. Then, through the synergistic action of the lower support rod 21 and the upper support rod 22, the support platform 3 is moved upward to achieve height adjustment. The weight is laterally distributed on the external thread of the horizontally set double-acting screw 24 by the connecting rod 23, thereby preventing its rotation and ensuring stability and precise control.

[0024] Fixed base 1 26 and fixed base 27 are located on the top of support base 1 and the bottom of support platform 3 respectively, and are arranged symmetrically from left to right. The symmetrical arrangement of fixed base 1 26 and fixed base 27 optimizes the mechanical balance, so that when adjusting the height of support platform 3, the force can be distributed more evenly, ensuring the stability of the structure.

[0025] One end of the double-acting lead screw 24 is fixedly connected to a hexagonal head 25, and the other end of the double-acting lead screw 24 is fixedly connected to a limiting piece. The limiting piece is designed to prevent the connecting rod 23 from accidentally falling off during the movement, thereby enhancing the stability of the structure. The hexagonal head 25 is designed to facilitate the user to rotate it with tools, thereby enabling convenient adjustment of the height of the support platform 3.

[0026] Please see Figure 2 , Figure 3 and Figure 5 Guide rods 31 are fixedly connected to the four corners of the bottom of the support platform 3. The guide rods 31 penetrate the interior of the support base 1 and slide with the support base 1 to ensure the stability of the support platform 3 during the lifting process.

[0027] The cover plate 5 is equipped with a fixing bolt that penetrates the support platform 3. The fixing bolt can stably fix the cover plate 5 to the support platform 3, ensuring the fixing and support effect of the steel bars and further enhancing the stability of the structure.

[0028] Please refer to Figure 4 and Figure 5 The support seat 1 comprises a base body 11, the front and rear sides of the base body 11 are fixedly installed with side support frames one 12, the outer side of the base body 11 is fixedly connected with an ear plate 13, the inner side of the ear plate 13 is movably hinged with a side support frame two 14, the bottom of the base body 11, the side support frame one 12 and the side support frame two 14 are fixedly installed with a stabilizing pad 15, the side support frame two 14 is rotated outward from the inner side of the ear plate 13, and the side support frame two 14 is perpendicular to the side of the base body 11, the side support frame two 14 cooperates with the front and rear side support frames one 12 of the base body 11 to provide support from the front, the rear and the side, thereby expanding the support area of the base body 11, in combination with the stabilizing pad 15, further enhancing the overall support stability, and improving the anti-toppling capability.

[0029] The side support frame one 12 and the side support frame two 14 are located outside the base body 11 and are arranged in left-right symmetry, ensuring stability when under stress, and the left-right symmetric side support frame one 12 and the side support frame two 14 can evenly share the load from different directions, effectively preventing tilting or deformation caused by uneven stress.

[0030] Working principle: in the initial state, when in use, the base body 11 is set at the target position, the side support frame two 14 is rotated outward from the inner side of the ear plate 13, the side support frame two 14 is perpendicular to the side of the base body 11, the side support frame two 14 cooperates with the front and rear side support frames one 12 of the base body 11 to provide support from the front, the rear and the side, thereby expanding the support area of the base body 11, in combination with the stabilizing pad 15 at the bottom of the base body 11, the side support frame one 12 and the side support frame two 14, further improving the support stability and the anti-toppling performance.

[0031] By rotating the hexagonal head 25, the hexagonal head 25 drives the bidirectional screw rod 24 inside the two side connecting rods 23 to rotate, since the two side connecting rods 23 are threadedly connected with the bidirectional screw rod 24, the rotation of the bidirectional screw rod 24 drives the two side connecting rods 23 to slide oppositely outside the bidirectional screw rod 24, when the connecting rod 23 slides inward, it pushes the lower support rod 21 and the upper support rod 22 between the fixed seat one 26 and the fixed seat two 27 to move, thereby pushing the support table 3 upward through the lower support rod 21 in cooperation with the upper support rod 22, so as to adjust the height, the upper steel bar is arranged in the clamping groove 4, and the cover plate 5 is installed above the support table 3 by using bolts to fix the upper steel bar, the above is the working process of the whole device, and the contents not described in detail in the specification all belong to the existing technology known to the person skilled in the art.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
