[0023] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model discloses a liftable and movable prefabricated T-beam steel bar binding membrane frame, comprising a mobile trolley 1, a positioning plate 2 for positioning horseshoe steel bars is arranged on the top of the mobile trolley 1, a plurality of horizontal positioning mechanisms 3 for positioning horizontal steel bars and a plurality of resistance increasing mechanisms 4 for increasing the friction between the mobile trolley 1 and the ground when working are arranged on the mobile trolley 1, and a height adjustment mechanism 5 for driving the horizontal positioning mechanism 3 and the resistance increasing mechanism 4 to move up and down is arranged on the mobile trolley 1.

[0025] The utility model arranges a horizontal positioning mechanism 3 and a positioning plate 2 on a mobile trolley 1, so that the composed steel bar binding membrane frame can directly carry out steel bar binding operations in a shed, and then be moved to the outside of the shed for hoisting after the binding is completed, thereby solving the problems of the existing steel bar binding positioning frame occupying the space of the prefabricated T-beam pedestal, the long secondary transportation distance of the semi-finished steel bars, and the long hoisting distance of the steel bar skeleton. By arranging a height adjustment mechanism 5 for adjusting the horizontal positioning mechanism 3, the height of the horizontal positioning mechanism 3 can be lowered after the steel bar binding is completed, so that the positioning rod in the horizontal positioning mechanism 3 no longer contacts the steel bars, thereby improving the subsequent separation efficiency of the positioning rods. By arranging a resistance increasing mechanism 4 that can be driven up and down by the height adjustment mechanism 5, the mobile trolley 1 can increase the friction resistance with the ground during the steel bar binding process, thereby improving the construction stability.

[0026] In one embodiment, the mobile trolley 1 includes a bottom plate 11 and a plurality of cross beams 12 disposed at the bottom of the bottom plate 11, the width of the cross beam 12 is greater than the width of the bottom plate 11, the positioning plate 2 is installed on the top of the bottom plate 11, and at least two universal wheels 13 are disposed at the bottom of the cross beam 12;

[0027] A trailer frame 6 which can be connected to a trailer and drive the mobile trolley 1 to move along is provided at one end of the mobile trolley 1 in the length direction.

[0028] With this design, the mobile trolley 1 and the prefabricated beam reinforcement located on the top of the mobile trolley 1 can be quickly transported by connecting the trolley frame 6 to the trailer.

[0029] In one embodiment, the horizontal positioning mechanism 3 includes at least one column 31 located at the top of the crossbeam 12, and a plurality of hollow sleeves 32 are arranged on the column 31. A positioning rod 33 capable of reciprocating along the width direction of the mobile trolley 1 is arranged on the hollow sleeve 32. A linkage plate 34 is arranged at one end of the positioning rod 33 away from the positioning plate 2, and the plurality of positioning rods 33 are fixedly connected to the linkage plate 34.

[0030] An anti-drop rope 35 is provided between the linkage plate 34 and the adjacent crossbeam 12 to prevent the positioning rod 33 from completely escaping from the hollow sleeve 32 .

[0031] With this design, after the height adjustment mechanism 5 drives the horizontal positioning mechanism 3 to move up to the set height, the linkage plate 34 is pushed to move toward the side of the positioning plate 2, so that the positioning rods 33 on the same horizontal positioning mechanism 3 can all move toward the positioning plate 2 synchronously, and the positioning rods 33 can be quickly moved to the point of supporting the horizontal steel bars. After the prefabricated beam steel bars are tied and the height adjustment mechanism 5 drives the horizontal positioning mechanism 3 to move downward, the linkage plate 34 can be pulled toward the side away from the positioning plate 2 to quickly move the positioning rods 33 out of the prefabricated beam steel bars, thereby improving the separation efficiency of the steel bar tying membrane frame and the prefabricated beam steel bars.

[0032] In one embodiment, the resistance increasing mechanism 4 includes a lower pressing plate 41 located at the bottom of the cross beam 12, at least one leg 42 penetrating the cross beam 12 and extending to the top of the cross beam 12 is arranged on the top of the lower pressing plate 41, and a tension spring 43 is arranged between the lower pressing plate 41 and the adjacent cross beam 12;

[0033] When the tension spring 43 is in a natural state, the lower surface of the lower pressing plate 41 does not contact the ground.

[0034] With this design, the height adjustment mechanism 5 drives the lower pressure plate 41 in the resistance increasing mechanism 4 to be pressed down against the ground, thereby increasing the contact area and friction between the mobile trolley 1 and the ground, and improving the stability of workers when tying steel bars. After the height adjustment mechanism 5 removes the downward pressure, the lower pressure plate 41 can be moved up and reset under the action of the tension spring 43, without affecting the transfer of the mobile trolley 1 to the trailer.

[0035] In a specific implementation, in order to increase the contact area with the rough ground, a rubber pad may be provided at the bottom of the lower pressing plate 41 .

[0036] In one embodiment, the height adjustment mechanism 5 includes a cover body 51 disposed on the top of the crossbeam 12, the cover body 51 is formed by splicing two half shells 511, a push block 52 capable of reciprocating along the length direction of the mobile trolley 1 is disposed in the cover body 51, a screw rod 53 capable of simultaneously adjusting the moving distance of multiple push blocks 52 is disposed on the cover body 51, the push block 52 is threadedly connected to the screw rod 53, one end of the screw rod 53 is provided with a hand wheel 54 for driving the screw rod 53 to rotate, and the other end of the screw rod 53 is fixed to the cover body 51 through a bearing;

[0037] The column 31 and the leg 42 are both inserted into the cover 51, and the push block 52 is located between the column 31 and the leg 42. The ends of the column 31 and the leg 42 close to the push block 52 are both provided with inclined surfaces inclined along the length direction of the mobile trolley 1, and the push block 52 is provided with a groove 55 adapted to the inclined surface;

[0038] When the tension spring 43 is in the natural state, the supporting leg 42 is in contact with the push block 52 .

[0039] With this design, the operator can change the position of the push block 52 in the cover 51 by turning the hand wheel 54 forward or reversely to change the height of the column 31 and the leg 42. Since the movement directions of the column 31 and the leg 42 are opposite when the push block 52 changes its position, when the steel bars are tied, the horizontal positioning mechanism 3 and the resistance increasing mechanism 4 can simultaneously enter the working preparation state before the steel bars are tied. After the steel bars are tied, the horizontal positioning mechanism 3 and the resistance increasing mechanism 4 can simultaneously enter the steel frame transfer and separation state, thereby improving the convenience and flexibility of construction.

[0040] In one embodiment, a guide rail 7 for limiting the installation height of the push block 52 is provided in the cover body 51, and the push block 52 can move back and forth along the guide rail 7. Such a design ensures that the gravity borne by the positioning rod 33 during the steel bar binding can not only be shared by the push block 52 to the support leg 42, but also can be shared to the cover body 51, thereby reducing structural fatigue and stress concentration.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
