DETAILED DESCRIPTION

[0018] 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. At the same time, it should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] like Figure 1 As shown, the utility model provides a hydraulic demoulding device for an end mold of a small box girder, comprising a mold plate 1 with a box girder placement cavity 15 arranged inside, one end of the mold plate 1 is connected to a first side truss 21, and the other end of the mold plate 1 is connected to a second side truss 22, an end mold 3 located on the side of the box girder placement cavity 15 is placed on the mold plate 1, an operating platform plate 4 is laid on the first side truss 21 and / or the second side truss 22, a main truss 23 located on the side of the mold plate 1 is detachably connected between the first side truss 21 and the second side truss 22, and a hydraulic demoulding component 5 for demoulding the end mold 3 is connected to the main truss 23.

[0020] During actual work, the operator can stand on the operating platform plate 4, and the hydraulic demoulding component 5 can enable the end mold 3 to realize the demoulding function when it shrinks. In this way, the present application solves the problem of demoulding by manpower, and its labor intensity is low and the work efficiency is high.

[0021] In the above technical solution, the hydraulic demoulding assembly 5 includes a plurality of hydraulic cylinders 51 arranged at intervals and installed on the main truss 23 , an ear seat 31 is connected to the end mold 3 , and the output end of the hydraulic cylinder 51 is detachably connected to the ear seat 31 via a connecting seat 53 .

[0022] During actual work, the output end of the hydraulic cylinder 51 is connected to a hydraulic connecting shaft 52 and a connecting seat 53 at one time. The hydraulic cylinder 51 is detachably connected to the ear seat 31 through the connecting seat 53. The operator can first use a lifting device to lift the small box girder end mold hydraulic demoulding device described in this application to a preset designated position, and then use a tie rod to fix the small box girder end mold hydraulic demoulding device described in this application to the side mold flange plate, and then connect the hydraulic cylinder 51 to the pump station, and extend the hydraulic cylinder 51 to the corresponding position, connect the top of the cylinder to the end mold 3 connecting ear seat 31 (using a pin shaft connection), and after the four cylinders are connected, the four cylinders are contracted synchronously. When contracting, the contraction amount is 2 cm each time. After the end mold 3 is separated from the concrete as a whole, the contraction amount can be accelerated, and then the hydraulic cylinder 51, the end mold 3 and the side mold are removed. In this way, the present application also realizes the demoulding process.

[0023] The shape of the end mold 3 matches the shape of the box beam, and at least two hydraulic cylinders 51 are arranged on the left side and / or the right side of the end mold 3, and the plurality of hydraulic cylinders 51 are in an inverted isosceles trapezoidal structure as a whole. In this way, the present application can more conveniently push the end mold 3 through four hydraulic cylinders 51, thereby realizing the demoulding process.

[0024] The main truss 23 is connected to a plurality of inclined support rods 24 at a side away from the first side truss 21. In this way, the main truss 23 not only has higher structural stability, but also has lower manufacturing cost.

[0025] The template 1 includes a first side template 11 connected to the first side truss 21, and a second side template 12 connected to the second side truss 22. The first side template 11 and the second side template 12 are arranged at intervals, and the shapes of the first side template 11 and the second side template 12 match the shapes of the side of the box beam. In this way, the present application also realizes the layout of the template 1 structure, making the present application more convenient to use.

[0026] A baffle 16 is connected to the top of the first side template 11 and / or the second side template 12 to isolate the template and the operating platform board 4, thereby making the application more convenient to use.

[0027] The first side formwork 11 and the second side formwork 12 both include a front formwork 13 located at the front end of the box beam placement cavity 15 and a rear formwork 14 located at the rear end of the box beam placement cavity 15 , the front formwork 13 is located between the box beam placement cavity 15 and the main truss 23 , and the end formwork 3 is placed on the front formwork 13 .

[0028] In actual work, when not in use, the present application can be placed on the ground, and when in use, the present application can perform the demoulding process of a single end mold 3 according to the above description, and after completing the demoulding process of a single end mold 3, the present application can perform the above demoulding process again at a designated position.

[0029] In summary, the advantages of the present application are as follows: 1. The present application no longer requires manual mold installation and demolding, saving a lot of labor costs; 2. The present application can be demolded as a whole, which is more convenient and quicker than the existing end mold 3 block disassembly; 3. The present application avoids the rough bending and hard warping of the existing end mold 3 during disassembly, effectively avoids the collapse of concrete corners, and ensures that the apparent quality of the small box girder meets the requirements.
