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

[0017] As Figure 1 shown, the present utility model provides a small box girder side form beam length automatic adjustment device, including a longitudinal sliding track 1 installed on the ground; a longitudinal oil cylinder 21 fixed on the longitudinal sliding track 1 and a transverse formwork base 3 slidably installed on the longitudinal sliding track 1 are installed on the longitudinal sliding track 1, and the output end of the longitudinal oil cylinder 21 is connected to the transverse formwork base 3 through a longitudinal connecting shaft 22; a transverse oil cylinder 4 is fixedly installed at one end of the transverse formwork base 3, and a transverse movement demolding base 5 is slidably arranged at the other end. A side form connection component 6 is installed on the transverse movement demolding base 5, and the output end of the transverse oil cylinder 4 is connected to a side form connecting shaft 41 located above the transverse movement demolding base 5.

[0018] During actual work, the transverse movement demolding base 5 can be connected to the side form through the side form connection component 6, and the transverse oil cylinder 4 can be connected to the side form through the side form connecting shaft 41. In this way, the present application can achieve the purpose of lateral movement of the side form through components such as the transverse oil cylinder 4 and the transverse movement demolding base 5; the longitudinal oil cylinder 21 can push the transverse formwork base 3 to move longitudinally through the longitudinal connecting shaft 22, and when the transverse formwork base 3 moves longitudinally, both the side form and the transverse movement demolding base 5 can move longitudinally. In this way, the present application can achieve the purpose of longitudinal movement of the side form; in this way, under the combined action of the transverse oil cylinder 4 and the longitudinal oil cylinder 21, the present application also solves the problem of manual demolding, with relatively low labor intensity and high work efficiency.

[0019] The side form connection component 6 includes side form fixing seats 61 installed on both sides of the transverse movement demolding base 5, and side form support seats 62 are rotatably connected to both ends of the side form fixing seats 61. During actual work, when the side form support seats 62 rotate, the connection angle between themselves and the side form can be adjusted, thereby further fixing the side form. In this way, under the combined action of multiple side form support seats 62, the present application can better achieve the lateral movement of the side form.

[0020] The side mold support base 62 includes a side mold rotating shaft 621 rotatably installed on the side mold fixed base 61. A side mold rotating seat 622 is installed on the side mold rotating shaft 621. A side mold support shaft 623 is installed on the side mold rotating seat 622. The central axis of the side mold support shaft 623 and the central axis of the side mold rotating shaft 621 are vertically intersecting. A side mold fixing member 624 for connecting the side mold is connected to the side mold support shaft 623. During actual operation, the side mold fixing member 624 can be well connected to the side mold as a whole. In this way, under the combined action of components such as the side mold fixing member 624, the side mold rotating shaft 621, and the side mold support shaft 623, the present application can better fix the side mold, enabling the side mold to more conveniently achieve lateral movement.

[0021] The side mold fixing member 624 includes an upper fixing nut 6241, a middle support member 6242, and a lower fixing nut 6243 that are sequentially sleeved on the side mold support shaft 623 from top to bottom. The upper fixing nut 6241 and the middle support member 6242 are arranged at intervals, and the lower fixing nut 6243 is connected to the middle support member 6242. During actual operation, the middle support member 6242 can be a spring to increase the structural stability of the present application.

[0022] The side mold fixed base 61 includes two side mold fixing plates 611 arranged at intervals. A plurality of side mold connecting plates 612 are connected between the two side mold fixing plates 611. The side mold support base 62 is located between the two side mold fixing plates 611.

A plurality of upright plates arranged at intervals are connected to the top of the transverse moving and demolding bottom plate 51. The side mold connecting shaft 41 is located above the upright plates. A plurality of transverse sliding holes 53 located below the upright plates are provided on the transverse moving and demolding bottom plate 51. In this way, the layout of the structure of the transverse moving and demolding base 5 is realized in the present application. Under the combined action of the transverse moving and demolding bottom plate 51, the plurality of upright plates, and the plurality of transverse sliding holes 53, the structural stability of the above-mentioned transverse moving and demolding base 5 is relatively high, and the manufacturing cost is relatively low.

[0025] During actual operation, the horizontal die base 3 can also be referred to as the demolding oil cylinder. The longitudinal sliding track 1 is fixed to the ground through embedded parts. The connection method between the embedded parts and the longitudinal sliding track 1 is welding connection. The side mold connection assembly 6 is connected to the side mold through the transverse demolding base 5. One end of the horizontal oil cylinder 4 is fixed on the horizontal die base 3, and the other end is used to fix the side mold (i.e., fixedly connected to the side mold). When the stroke of the horizontal die base 3 changes, the side mold (plate) and the side mold connection assembly 6 can slide together on the horizontal die base 3 to play the role of demolding and mold closing.

[0026] During actual operation, one end of the output end of the longitudinal oil cylinder 21 is fixed on the longitudinal sliding track 1, and the other end is fixed on the horizontal die base 3. According to the retraction and extension of the longitudinal oil cylinder 21, the structure except the longitudinal sliding track 1 can be driven to move in a specified direction, and the moving distance is determined according to the beam type precast on site.

[0027] In summary, the present application improves the automation level of template length adjustment, and has high working efficiency and safety.

[0028] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
