Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a translation device for tower crane precast composite slabs. Background Technique

[0002] A precast composite slab is an assembled monolithic floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. It has good integrity, high stiffness, and can save formwork. Reinforcing bar peaks are embedded at intervals on the top surface of the precast composite slab as the steel bar protection layer for the cast-in-place layer.

[0003] In the existing method of using a tower crane to translate precast composite slabs, generally a "day"-shaped frame is adopted. Lifting points are arranged at the bottom of the frame, and the lifting points are connected to the precast composite slab through suspension ropes for translation. With the above lifting and translation structure, due to the fixed size of the frame and inability to adjust, the adaptability is poor, and it cannot be used for the translation and lifting of precast composite slabs of different specifications. Only by adjusting the length of the suspension ropes can it adapt to composite slabs of different sizes. However, too long suspension ropes are likely to cause a decrease in stability, and it is also time-consuming and laborious to replace the suspension ropes. Content of the Utility Model

[0004] The utility model aims to provide a translation device for tower crane precast composite slabs that can solve the above problems to overcome the above situations.

[0005] A translation device for tower crane precast composite slabs includes a suspension frame, an upper connection structure, and a lower connection structure. The suspension frame includes two horizontally arranged frames that are parallel to each other and connecting rods that are cross-arranged between the two horizontally arranged frames. One end of the connecting rod is hinged to one of the horizontally arranged frames, and the other end is slidably and fixedly connected to and hinged to the other horizontally arranged frame. The middle parts of the two horizontally arranged frames are hinged. The upper connection structure includes upper lifting lugs fixed at both ends of the top surface of the horizontally arranged frame, a lifting ring arranged above the suspension frame, and an upper suspension rope connecting the upper lifting lugs and the lifting ring. The lower connection structure includes lower lifting lugs fixed to the bottom surface of the horizontally arranged frame and a lower suspension rope connecting the lower lifting lugs and the precast composite slab.

[0006] Furthermore, connecting ear plates are fixed on one side of the two horizontally arranged frames that are close to each other, and one end of the connecting rod is hinged to the connecting ear plate through a first hinge shaft.

[0007] Furthermore, adjusting plates are fixed on one side of the two horizontally arranged frames that are close to each other. A plurality of adjusting holes are arranged along the length direction of the horizontally arranged frame on the adjusting plates. One end of the connecting rod away from the first hinge shaft is rotatably connected with an adjusting bolt, and the adjusting bolt passes through the adjusting hole and is connected to the adjusting plate.

[0008] Furthermore, the vertical cross-section of the adjusting plate is a U-shaped structure with an opening facing the horizontally arranged frame. The connecting rod is inserted into the adjusting plate, and the adjusting holes are correspondingly arranged on the upper and lower wing plates of the adjusting plate.

[0009] Furthermore, a hydraulic cylinder is fixed on one side of the two cross frames close to each other along the length direction of the cross frames, and an end of the connecting rod away from the first hinge shaft is hinged with a connecting plate through a second hinge shaft, and the connecting plate is fixedly connected to the hydraulic cylinder.

[0010] Furthermore, a slide groove is provided on one side of the two cross frames close to each other, and a slider is fixed on one side of the connecting plate close to the cross frame, and the slider is adapted to the slide groove and slides in the slide groove.

[0011] Furthermore, the connecting plate is in a U-shaped structure with an opening away from the hydraulic cylinder, the hydraulic cylinder is fixedly connected to the web of the connecting plate, and the connecting rod is inserted between two wing plates of the connecting plate.

[0012] Furthermore, the plurality of lower hanging ears are arranged at equal intervals along the length direction of the cross frame.

[0013] Furthermore, a D-shaped shackle is provided at the upper end of the lower lifting rope and is connected to the lower lifting ear.

[0014] Furthermore, a self-locking hook is provided at the lower end of the lower sling and is connected to the prefabricated composite plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The tower crane prefabricated composite plate translation device in the utility model is composed of two cross frames and connecting rods cross-arranged between the two cross frames. One end of the connecting rod is hinged to one of the cross frames, and the other end is slidably fixedly connected and hinged to the other cross frame. Therefore, by changing the crossing angle of the two connecting rods, the position of one end of the connecting rod slidably connected to the cross frame can be changed, thereby adjusting the distance between the two cross frames, that is, adjusting the width of the hanger, so that the hanger can adapt to prefabricated composite plates of different sizes, and there is no need to replace lower slings of different lengths, and the adaptability is wide.
