Detailed implementation manners

[0021] As Figure 1-6 shown, a mobile drainage ditch formwork includes a hanger frame 1. The two ends of the hanger frame 1 can be respectively lapped on both sides of the drainage ditch, and a lifting and moving mechanism is provided. At the bottom of the hanger frame 1, there are two symmetrically arranged external side formworks 2 and an inner formwork assembly located between the two external side formworks 2. The inner formwork assembly includes two symmetrically arranged internal side formworks 3 and an internal bottom formwork 5 movably arranged between the two internal side formworks 3. The external side formwork 2 and the internal side formwork 3 are both hinged to the bottom of the hanger frame 1. The two external side formworks 2 can be demolded by turning outwards, and the two internal side formworks 3 can be demolded by turning relatively. On the bottom of the opposite sides of the two internal side formworks 3, there are slope fittings 301, and on both sides of the internal bottom formwork 5, there are abutting slopes adapted to the slope fittings 301. When the bottom surface of the internal bottom formwork 5 is flush with the ground surface of the internal side formwork 3, the angle of the internal side formwork 3 meets the design requirements. The width of the internal bottom formwork 5 is smaller than the width between the two internal side formworks 3. When the internal bottom formwork 5 rises, the two internal side formworks 3 can turn towards the opposite sides to achieve demolding. At the inner edge of the top of the external side formwork 2, there is an external formwork limit plate 201, which achieves the limiting effect by abutting against the hinge seat. At the outer edge of the top of the internal side formwork 3, there is an internal formwork limit plate 303, which achieves the limiting effect by abutting against the hinge seat. On both sides of the internal bottom formwork 5, there are also lifting ropes 7 respectively connected to the two internal side formworks 3. Between the outer side of the external side formwork 2 and the bottom of the hanger frame 1, there is an opening and closing telescopic cylinder 4, and on the hanger frame 1, there is also a lifting mechanism 6 for controlling the lifting of the internal bottom formwork 5.

[0022] When in use, the hanger frame 1 is erected on both sides of the drainage ditch, and the inner bottom template 5 is lowered between the two inner side templates 3 through the lifting mechanism 6, and the contact and sliding guidance is carried out through the contact slope and the matching slope 301. At the same time, the inner membrane limiting plate 303 is used to limit the bottom surface of the inner bottom template 5 and the bottom surface of the inner side template 3. At this time, the contact slope of the inner bottom template and the matching slope 301 are in contact, which can play the role of template support. Then, the outer side template 2 is flipped to the supporting position by the top push of the opening and closing telescopic cylinder 4. In the process, the outer template limiting plate 201 plays a limiting role again, and finally the lifting and moving The dynamic mechanism is lowered to make the template fall on the drainage ditch cushion layer. After the end templates are installed at the front and rear ends and reinforced as a whole, the drainage ditch can be poured. After completing the pouring of this stage, the end templates and reinforcement are removed, and then the internal bottom template 5 is lifted by the lifting mechanism 6. When the internal bottom template 5 is lifted to the first height, the lifting rope 7 is straightened, and the two internal side templates 3 are rotated inwardly, so that the two internal side templates 3 are demoulded, and then the telescopic cylinder 4 is opened and closed to contract, and the two external side templates 2 are driven to rotate outwards to complete the demoulding, and then the lifting and moving mechanism is used to lift the entire device and move it to the next casting section, and the above process is repeated.

[0023] In the preferred embodiment, the hanger frame 1 includes a plurality of support beams 101 with a length greater than the width of the drainage ditch. A connecting longitudinal beam 102 is arranged between the middle parts of the support beams 101. The casting of the formwork can be completed through the spacing between the support beams 101. Both ends of the support beams 101 are provided with a lifting and moving mechanism. The lifting and moving mechanism includes a lifting cylinder 105 which is arranged through the end of the support beam 101. The output end of the lifting cylinder 105 passes through the support beam 101 and is connected to a moving wheel 104.

[0024] In a preferred embodiment, movable tracks matching the movable wheels 104 are provided on both sides of the drainage ditch, and the movable wheels 104 are slidably arranged on the movable tracks.

[0025] In the preferred embodiment, a through hole 103 for installing the lifting mechanism 6 is provided on the connecting longitudinal beam 102. The lifting mechanism 6 is a lifting telescopic cylinder, and its telescopic end passes through the through hole 103 and is connected to the top of the internal bottom template 5, thereby achieving the lifting effect of the controller.

[0026] In the preferred embodiment, the cross-section of the inner bottom template 5 is hexagonal, and the slope of the top side surface facilitates increasing the distance between the two ends of the suspension rope 7, which helps to pull the inner side template 3 to rotate inward during lifting.

[0027] In a preferred embodiment, a connecting plate 302 extending towards the separated side is further provided at the top of the two inner side templates 3. The cross-section of the connecting plate 302, the inner side template 3 and the fitting slope 301 is Z-shaped. The hinge point between the inner side template 3 and the hanger frame 1 and the inner membrane limiting plate 303 are both located at the edge of the connecting plate 302 away from the inner side template 3, thus effectively increasing the distance between the hinge point and the pulling point, and further helping to pull the inner side template 3 to rotate inwards.

[0028] In a preferred embodiment, it further includes an end mold detachably arranged at the end of the outer side template 2 and the inner components. In this embodiment, the end mold can be fixed to the ends of the outer side template 2 and the inner components by bolts.

[0029] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
