DETAILED DESCRIPTION
[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0021] like Figures 1 to 5As shown, an embodiment of the utility model proposes a handling device for hollow floor slabs at a construction site, which includes a lifting rod 1, the two ends of which are flat, a load-bearing shaft 102 is fixedly provided in the middle, and a C-shaped seat 3 is rotatably provided on the load-bearing shaft 102; two groups of clamping arms 2 are mirror-hinge-connected to the C-shaped seat 3, each clamping arm 2 includes a suspension arm 202 and a clamping block 203 fixedly connected to one end of the suspension arm 202, and the two clamping blocks 203 are used to clamp the hollow floor slab body 100; a safety arm 4 includes a rotating arm 5 with one end hinged to any one of the clamping arms 2 and an extension arm 6 adjustably arranged at one end of the rotating arm 5, one end of the extension arm 6 is detachably connected to the other clamping arm 2, and the safety arm 4 is used to limit the opening and closing of the two clamping arms 2.
[0022] The detailed working process of this embodiment is as follows: the two ends of the lifting rod 1 are flat, which can increase the force-bearing area and reduce the burden. The function of the clamping block 203 is to be clamped in the hollow part of the hollow floor slab body 100.
[0023] The hollow floor slab is clamped by two sets of clamping arms 2, and then two workers carry it through the lifting rod 1, which can solve the damage caused by manual carrying. At the same time, after clamping, it is limited and fixed by the safety arm 4 to prevent the two clamping arms 2 from opening and slipping of the floor slab during transportation. The C-shaped seat 3 is rotatably set on the control rod 201, so that the two clamping arms 2 can be rotated and adjusted in direction during the clamping process, thereby improving flexibility.
[0024] like Figure 3 As shown, a control panel 501 is provided at the hinged end of the rotating arm 5, an extension arm 6 is provided at the end of the rotating arm 5 away from the hinge point through an adjusting rod 7, a bending portion 601 is provided at the end of the extension arm 6 away from the rotating arm 5, and a limiting axis 206 is provided on the clamping arm 2 that is not hinged to the rotating arm 5, and the bending portion 601 is overlapped on the limiting axis 206.
[0025] The detailed working process of this embodiment is as follows: the rotating arm 5 is hinged on any one of the clamping arms 2, and the rotating arm 5 can be rotated around the hinge point by controlling it through the control panel 501. An extension arm 6 is provided through the adjusting rod 7, so that the extension arm 6 can be adjusted to change the length of the safety arm 4 to adapt to the opening degree of the two clamping arms 2. The bent portion 601 at one end of the extension arm 6 is hooked on the limit shaft 206. At this time, the two clamping arms 2 are restricted, which can ensure safety during the process of clamping and transporting the floor slabs.
[0026] like Figure 3 and Figure 4 As shown, the adjusting rod 7 includes a cylindrical portion 701 and a threaded portion 702. A threaded hole 502 is provided on the rotating arm 5. The threaded portion 702 is located in the threaded hole 502 and is threadedly connected. A through hole 602 is provided in the extension arm 6. The cylindrical portion 701 is located in the through hole 602 and is rotatable.
[0027] like Figure 3 and Figure 5 As shown, a limiting hole 603 is provided in the through hole 602 , a limiting ring 703 is provided on the cylindrical portion 701 , and the limiting ring 703 is located in the limiting hole 603 .
[0028] The detailed working process of this embodiment is as follows: the threaded portion 702 is threadedly connected to the rotating arm 5, and the cylindrical portion 701 is connected to the extension arm 6. At the same time, the setting of the limiting ring 703 and the limiting hole 603 allows the cylindrical portion 701 to rotate in the extension arm 6 while preventing it from moving. The relative position of the extension arm 6 and the rotating arm 5 is adjusted by rotating the adjusting rod 7 to change their length.
[0029] like Figure 2 As shown, each boom 202 is provided with a receiving slot 205 , and a control rod 201 is rotatably provided in each receiving slot 205 , wherein the safety arm 4 and the limiting shaft 206 are respectively located in the corresponding receiving slot 205 .
[0030] The detailed working process of this embodiment is as follows: the function of the control lever 201 is to control during transportation to avoid shaking during movement, wherein the safety arm 4 and the limit shaft 206 are respectively located in the corresponding storage groove 205, and the safety arm 4 and the limit shaft 206 can be stored in the safety arm 4 when not in use.
[0031] like Figure 2 As shown, pads 101 are provided at both ends of the lifting rod 1.
[0032] The detailed working process of this embodiment is as follows: the pad 101 is placed on the shoulder to reduce direct contact between the heavy object and the skin, thereby reducing friction and protecting the skin from damage. This is especially important for workers who carry heavy objects for long periods of time or frequently, as it can avoid abrasion and pain on the shoulder skin.
[0033] like Figure 2 As shown, each clamping block 203 is provided with a rubber pad 204 .
[0034] The detailed working process of this embodiment is as follows: the function of the rubber pad 204 is to increase the friction force, while preventing the clamping block 203 from directly and rigidly contacting the hollow floor slab, thereby preventing the wear of the hollow floor slab.
[0035] like Figure 3 As shown, a hexagonal prism 704 is provided at one end of the cylindrical portion 701 away from the threaded portion 702 , and the hexagonal prism 704 is located outside the through hole 602 .
[0036] The detailed working process of this embodiment is as follows: the function of the hexagonal prism 704 is to enable the use of different tools to twist the adjustment rod 7 to rotate.
[0037] The implementation principle of the embodiment of the present application is: first, open the two clamping arms 2 and align the corresponding clamping blocks 203 with the two ends of the hollow floor slab body 100 and clamp them in the quasi-hollow floor slab body 100, then adjust the safety arm 4 according to the opening degree of the two clamping arms 2. During adjustment, rotate the adjusting rod 7 so that the bending part 601 overlaps the limit shaft 206, and the hollow floor slab can be lifted and transported. After transporting to the designated position, drive the control board 501 to rotate so that the bending part 601 is separated from the limit shaft 206 and can be opened to complete the transportation.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
