DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Embodiment one:

[0025] As shown in Figure 1 and Figure 2 , the cast-in-place continuous box girder side formwork sliding device in the present embodiment comprises, from top to bottom, a side formwork, a support mechanism, a support platform 1, a lifting mechanism, a frame body 2 and a moving mechanism. The support mechanism is arranged between the support platform 1 and the side formwork, and is used for supporting the side formwork. The frame body 2 is arranged below the support platform 1, and the frame body 2 is located at the side of the bridge column, so as to lift the support platform 1. The lifting mechanism is arranged between the support platform 1 and the frame body 2, so as to adjust the height of the support platform 1, so that different heights of bridge columns can be adapted. The moving mechanism is installed at the bottom of the frame body 2, so as to drive the frame body 2 to move.

[0026] In the embodiment, the side formwork comprises a vertical formwork 3, a first inclined formwork 4 and a second inclined formwork 5, wherein the first inclined formwork 4 is fixed to the lower end of the vertical formwork 3, and the lower end of the first inclined formwork 4 is hinged to the upper end of the second inclined formwork 5. The supporting mechanism comprises a first hydraulic cylinder 6 and a second hydraulic cylinder 7, the first hydraulic cylinder 6 is vertically arranged and the upper and lower ends thereof are fixedly connected with the supporting platform 1 and the first inclined formwork 4 respectively, and the two ends of the second hydraulic cylinder 7 are hinged with the supporting platform 1 and the second inclined formwork 5 respectively.

[0027] By arranging the first hydraulic cylinder 6 and the second hydraulic cylinder 7, the height of the side formwork is finely adjusted by the first hydraulic cylinder 6 and the second hydraulic cylinder 7, which facilitates the demolding after the box girder is formed. The side formwork is composed of the vertical formwork 3, the first inclined formwork 4 and the second inclined formwork 5, and the second inclined formwork 5 is hinged to the first inclined formwork 4, so that the angle of the second inclined formwork 5 can be finely adjusted to adapt to different box girders to a certain extent.

[0028] In the embodiment, the bottom surfaces of the first inclined formwork 4 and the second inclined formwork 5 are both provided with vibration motors 10, which further facilitates the demolding of the side formwork after the box girder is formed.

[0029] In the embodiment, the lifting mechanism is a scissor lifting frame 9. The moving mechanism comprises a moving wheel system 8 and a parking system. Preferably, the moving wheel system 8 is an independent suspension wheel system, which is a prior art, and thus the specific structure of the independent suspension wheel system is not described in detail here. The independent suspension wheel system has strong buffering and damping capacity, and the wheels on both sides can move independently without affecting each other, thereby adapting to the uneven ground condition of the bridge construction. The parking system comprises a parking hydraulic cylinder 13 and a fixed plate 14, the parking hydraulic cylinder 13 is vertically arranged and the upper and lower ends thereof are fixedly connected with the frame body 2 and the fixed plate 14 respectively. When the frame body 2 moves to the construction position, the parking hydraulic cylinder 13 is elongated, so that the fixed plate 14 contacts the bottom surface and lifts the frame body 2, and the wheels in the independent suspension wheel system are lifted off the ground, thereby fixing the position of the frame body 2.

[0030] The cast-in-place continuous box girder side formwork sliding device in the embodiment lifts the supporting platform 1, the supporting mechanism and the side formwork by arranging the frame body 2, so that the side formwork is supported above the bridge column, thereby enabling the cast-in-place continuous box girder to be directly cast on the bridge column, thereby saving the existing process of hoisting after the box girder is formed. After the cast-in-place box girder is formed, the frame body 2 is moved to the next section by the moving mechanism for continuous use.

[0031] Embodiment two:

[0032] As Figure 3As shown, the cast-in-place continuous box girder side formwork sliding device in the embodiment further comprises a ladder 11 arranged on the side of the support platform 1 away from the side formwork, specifically, the ladder 11 is arranged obliquely, and a stiffening bar 15 is further arranged between the side of the frame body 2 away from the bridge column and the ladder 11, so as to ensure the stability of the ladder 11. A protective fence 12 is arranged on the top edge of the support platform 1, the protective fence 12 avoids the moving position of the second hydraulic cylinder 7, and a switchable protective door (not shown in the figure) is arranged at the corresponding position of the protective fence 12 and the ladder 11. By arranging the ladder 11, the staff can climb to the top of the support platform 1, and the arrangement of the protective fence 12 can protect the staff on the support platform 1.
