[0013] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0014] like Figure 1 As shown, a steel-concrete composite beam formwork hoisting device includes a traveling guide rail 1, traveling wheels 2, supporting longitudinal plates 3, supporting crossbeams 4, a winch placement box 5, a winch 6, and a counterweight box 7.

[0015] The traveling guide rail 1 is a longitudinal steel pipe supporting the uprights on the formwork 8. It is used to support the weight of the formwork 8 itself, as well as the weight of the reinforcing steel and concrete on the formwork 8. It can also be used as the traveling guide rail 1 of the hoisting formwork device. There are two traveling guide rails 1, which are set at intervals on the left and right.

[0016] The traveling wheels 2 are rollers that conform to the shape of the steel pipe and are set at the bottom of the supporting longitudinal plate 3. There are two supporting longitudinal plates 3, which are set on the traveling guide rail 1 at intervals on the left and right, and can move back and forth on the traveling guide rail 1 by means of the traveling wheels 2.

[0017] The support beam 4 is vertically fixed to the two support longitudinal plates 3. There are three winch placement boxes 5. The three winch placement boxes 5 are fixed to the support beam 4 at intervals along the length of the support beam 4, and are respectively fixed to the left and right sides of the two support longitudinal plates 3 and between the two support longitudinal plates 3, with the positions corresponding to the left wing template, the middle template and the right wing template.

[0018] The winch 6 can be installed in an adjustable position on any winch placement box 5. The winch placement box 5 is provided with holes through which the hoisting rope 61 of the winch 6 passes to the ground for connection with the formwork 8, so as to realize the hoisting of the formwork 8.

[0019] The counterweight box 7 is fixed to the bottom of the support longitudinal plate 3 and is used to place counterweight blocks to balance the left and right sides of the support beam 4.

[0020] The use process of the formwork device is as follows: the formwork 8 is assembled on the ground; the winch 6 is installed on the corresponding winch placing box 5 according to whether the formwork 8 is a left wing formwork or a right wing formwork or a middle formwork; the formwork hoisting rope 61 of the winch 6 is extended from the hole to the ground and connected with the formwork 8; the counterweight block is placed on the counterweight box 7 according to the position of the winch 6, for example, the formwork 8 is a left wing formwork, the winch 6 is installed on the left winch placing box 5, then the counterweight block is placed on the right counterweight box 7 to balance the left and right sides of the support beam 4. The formwork 8 is hoisted by the winch 6, after the hoisting is completed, the formwork device is moved to the installation position of the next formwork 8 by the walking wheel 2, the above operation is repeated to complete the installation of the formwork 8 before the concrete pouring of the steel concrete composite beam bridge deck.
