DETAILED DESCRIPTION

[0020] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 , the utility model provides embodiments:

[0022] A prefabricated building formwork lifting equipment comprises a beam body 1 and a building formwork 2, main body brackets 3 are arranged in parallel on both sides of the beam body 1, the building formwork 2 is hoisted below the beam body 1 through a connecting mechanism 4, the building formwork 2 is arranged in parallel between the two main body brackets 3 through a positioning mechanism 5, the positioning mechanism 5 comprises a positioning plate 51, a slider 52, a connecting arm 53 and a pull rod 54, the positioning plate 51 is attached to the surface of the building formwork 2, the slider 52 is slidably arranged on the surface of the positioning plate 51 through a track, one end of the connecting arm 53 is hinged to the surface of the slider 52 through a torsion spring, the other end of the connecting arm 53 is hinged to the surface of the main bracket 3 through a torsion spring, the pull rod 54 is fixed to the surface of the positioning plate 51 and vertically penetrates the main bracket 3, and a supporting structure 6 is arranged at the bottom of the two main brackets 3.

[0023] See also Figure 1 , 2and 4. By pulling the pull rod 54, the positioning plate 51 can be driven to move horizontally toward the direction close to the main support 3. Since one end of the connecting arm 53 is hinged on the main support 3, its vertical height will not change. Therefore, when the positioning plate 51 moves horizontally, the track can drive the slider 52 to move slightly upward in the vertical direction, and the slider 52 and the connecting arm 53 will also rotate. At this time, multiple torsion springs are deformed and energy is stored, and then the main support 3 is moved horizontally to the building formwork 2 and the pull rod 54 is released. Under the elastic force of the torsion spring, the positioning plate 51 can be in contact with the building formwork 2. At this time, the building formwork 2 is located exactly in the middle of the two main supports 3, and the building formwork 2 and the main support 3 are both perpendicular to the ground. Moreover, no matter whether the specifications of the building formwork 2 are large or small, it can be positioned by the positioning plate 51.

[0024] The connecting mechanism 4 includes a traction block 41, a bottom hook 42 and a threaded rod 43. The threaded rod 43 is rotatably set on the beam body 1. The traction block 41 is slidably set on the beam body 1 and is connected with the threaded rod 43. The bottom hook 42 is installed at the bottom of the traction block 41.

[0025] See also Figure 1 and 5 Through the existing technology, the joint can be directly installed on the top surface of the building template 2, and then the two ends of the steel cable are respectively connected to the joint and the bottom hook 42. Since the specifications of the building template 2 are not certain, it is necessary to rotate the threaded rod 43 after the steel cable is installed, so that the threaded rod 43 drives the traction block 41 to move horizontally on the beam body 1, and then the traction block 41 drives the bottom hook 42 to move synchronously. At this time, the bottom hook 42 can tighten the steel cable, thereby facilitating the lifting of the building template 2 by the beam body 1. At this time, the whole is lifted from the hook on the top of the beam body 1 by the crane to realize the transportation of the building template 2.

[0026] It should be noted that if Figure 5 As shown, assuming that the joints of the building template 2 are located on both sides of its top surface, when the joints are connected to the bottom hooks 42 by steel cables, it is necessary to drive the bottom hooks 42 to move toward the direction close to the central area of ​​the beam body 1 to achieve tensioning of the steel cables. If the joints are located in the middle of the top surface of the building template 2, it is necessary to drive the bottom hooks 42 to move away from the central area of ​​the beam body 1. The position of the bottom hooks 42 needs to be adjusted according to the installation position of the joints of the building template 2.

[0027] The supporting structure 6 includes a connecting seat 61 movably arranged at the bottom of the main support 3 through the storage structure 7, and a bottom baffle 62 fixedly arranged between the two connecting seats 61 through a connecting member 8, and the top of the bottom baffle 62 contacts the bottom of the main support 3 and the building template 2.

[0028] See also Figure 1 and 2 After the positioning plate 51 realizes the positioning of the building template 2, the beam body 1 is lifted as a whole by a crane. At this time, the bottom baffle 62 needs to be installed on the bottom of the main bracket 3 in a lateral pushing manner to realize the support of the building template 2 by the bottom baffle 62. On the one hand, it can limit the building template 2. If the steel cable breaks, the bottom baffle 62 can prevent the building template 2 from falling from the bottom of the beam body 1. On the other hand, the bottom baffle 62 can share part of the gravity of the building template 2, thereby increasing the service life of the steel cable.

[0029] It should be noted that, in order to facilitate the installation of the bottom baffle 62, it is necessary to first lift the beam body 1 as a whole by a crane during installation. However, when the bottom baffle 62 is removed after transportation, the bottom baffle 62 can be directly placed on the ground or floor. After the beam body 1 is separated from the building formwork 2 (that is, the steel cable is removed), the connecting piece 8 is removed, and then the main body bracket 3 is moved horizontally to separate the main body bracket 3 from the surface of the building formwork 2 and the bottom baffle 62. Finally, the bottom baffle 62 can be reused after the building formwork 2 is installed on the building.

[0030] The storage structure 7 includes a spring 71, a guide rod 72, a cavity 73 and a receiving groove 74. The receiving groove 74 is arranged at the bottom of the main bracket 3, the cavity 73 is arranged at the top of the receiving groove 74, the guide rod 72 is fixed to the top of the connecting seat 61, the connecting seat 61 is slidably arranged in the receiving groove 74, the top end of the guide rod 72 is slidably arranged in the cavity 73, and the top end of the guide rod 72 is fixed to the top of the cavity 73 by the spring 71.

[0031] See also Figure 3 When the bottom baffle 62 and the connecting seat 61 are in a connected state, the connecting seat 61 moves down to the lowest point inside the accommodating groove 74. At this time, the connecting seat 61 drives the guide rod 72 to move down synchronously. When the guide rod 72 moves down, it can pull the spring 71 to store energy. When the bottom baffle 62 and the connecting seat 61 are in a separated state, the spring 71 can drive the guide rod 72 to reset inside the cavity 73 through its own elastic force, so that the connecting seat 61 is reset in the accommodating groove 74. At this time, the connecting seat 61 moves to the highest point, and its bottom is flush with the bottom of the main bracket 3.

[0032] The connecting member 8 is configured as a bolt, and the side walls of the connecting seat 61 and the side walls of the bottom baffle 62 are both provided with threaded holes, and the bolts are connected in cooperation with the threaded holes. A recessed portion 9 is provided on the side of the bottom baffle 62, and a protruding portion 10 is provided on the inner wall of the connecting seat 61. The protruding portion 10 is connected in cooperation with the recessed portion 9, and the threaded holes on the surface of the connecting seat 61 extend to the surface of the protruding portion 10.

[0033] See also Figure 3The bolts can realize the connection between the bottom baffle 62 and the connecting seat 61 through the two threaded holes, and in the process of installing the bottom baffle 62 on the connecting seat 61, the cooperation of the protrusion 10 and the recessed portion 9 can make the bottom baffle 62 translate in the horizontal direction, so as to facilitate the alignment of different threaded holes on the bottom baffle 62 and the connecting seat 61 to facilitate the installation of the bolts. At the same time, the cooperation of the protrusion 10 and the recessed portion 9 can increase the contact area between the bottom baffle 62 and the connecting seat 61, thereby improving the longitudinal supporting force between the two.
