DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figure 1-5 The utility model provides a technical solution: a hole-opening device for construction of composite plates which can prevent deviation, comprising a base 1, a universal wheel 2, a fixed column 3, a support frame 4, a first spring 5, a fixed plate 6, a fixed block 7, a convex block 8, a movable plate 9, a connecting plate 10, a movable rod 11, an auxiliary block 12, a second spring 13, a fixed groove 14, a fixing mechanism 15, a support plate 16, a connecting bolt 17, a convex plate 18 and a pressure plate 19.

[0033] When using the hole-opening device for anti-deviating composite slab construction, if Figure 1 , Figure 2 and Figure 3 As shown, first, the universal wheel 2 installed at the lower end of the base 1 drives the device to move to the opening position of the composite plate, and then the universal wheel 2 is locked to fix the device. Then, according to the actual size of the composite plate, the fixing plate 6 is pulled upward, and the fixing plate 6 slides with the fixing block 7. The fixing plate 6 squeezes the first spring 5, so that the first spring 5 is elastically deformed, and the fixing plate 6 is separated from the protrusion 8, thereby releasing the limit between the support frame 4 and the fixing column 3. The protrusions 8 are arranged at equal intervals in the middle of the upper end of the base 1. By pulling The movable support frame 4 slides between the support frame 4 and the fixed column 3, and the support frame 4 drives the fixing mechanism 15 to move, so as to facilitate the adjustment of the spacing between the fixing mechanisms 15 and the fixing mechanisms 15 on the left and right sides of the upper end of the base 1, so as to facilitate the processing of composite plates of different lengths. After the adjustment is completed, the fixing plate 6 is directly released, and the first spring 5 restores the elastic deformation at this time, driving the fixing plate 6 to move downward, so that the fixing plate 6 slides with the fixing block 7, and the fixing plate 6 is engaged with the convex block 8 at the corresponding position of the upper end of the base 1;

[0034] This facilitates the positioning of the support frame 4 and the fixed column 3. Figure 3 , Figure 4 and Figure 5 As shown, according to the width of the composite plate, by pulling the movable rod 11, the movable rod 11 slides with the connecting plate 10, and the movable rod 11 drives the auxiliary block 12 to slide with the movable plate 9, and the auxiliary block 12 squeezes the second spring 13, so that the second spring 13 is elastically deformed, and the movable rod 11 drives the auxiliary block 12 to disengage from the fixing groove 14, thereby releasing the limit between the support frame 4 and the movable plate 9, and then by pulling the movable plate 9 back and forth, the movable plate 9 slides on the upper end of the support frame 4, so as to facilitate the adjustment of the spacing between the fixing mechanisms 15 and the fixing mechanisms 15 on the front and rear sides of the upper end of the support frame 4, so as to facilitate the fixing of composite plates of different widths;

[0035] After the adjustment is completed, the movable rod 11 is directly released. At this time, the second spring 13 restores its elastic deformation, so that the movable rod 11 drives the auxiliary block 12 to engage in the fixing groove 14 at the corresponding position, thereby facilitating the limiting of the movable plate 9 and the support frame 4. After the limiting is completed, through the setting of the fixing mechanism 15, the fixing mechanism 15 includes a supporting plate 16 fixedly connected to the inner side of the movable plate 9, a connecting bolt 17 for adjustment, a convex plate 18 for connection, and a pressing plate 19 fixedly connected to the lower end of the convex plate 18, the superimposed plate is placed on the support frame 4. The bottom of the support plate 16 is supported, and the support plate 16 is dispersed at equal angles at the edge of the lower end of the composite plate, and then the pressure plate 19 drives the convex plate 18 to be connected to the lower end of the connecting bolt 17 through the slot, and the connecting bolt 17 threadedly connected to the upper end of the support plate 16 is rotated, and the lower end of the connecting bolt 17 and the convex plate 18 are rotated, thereby driving the pressure plate 19 to retract and retract, so that the pressure plate 19 moves downward to stably press and fix the composite plate on the support plate 16. After positioning, the composite plate is expanded, and the overall stability is relatively high.

[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.
