Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to a temporary support device for heavy objects. Background Technology

[0002] If a bridge crane experiences a major malfunction while lifting a load, rendering all mechanisms inoperable and unable to resolve the issue quickly, the load suspended in the air faces risks such as falling, crushing, collisions, and fatigue damage to the crane itself. In such cases, the load can be lowered manually. However, if the load is spherical or irregularly shaped, making good contact with the ground, or if the bottom of the load cannot support the weight, or if the load carrier is not easily moved to directly beneath the load, a suitable matching device is required to support it on the ground. Furthermore, since loads vary in shape and weight, the versatility of the supporting device requires specialized design; currently, there are no universally applicable products on the market. Utility Model Content

A limit hole is opened in the center of the bottom flange cover.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This application provides a temporary support device for heavy objects, which solves the problem that support devices cannot adapt to supporting heavy objects of spherical or irregular shape and different weight specifications.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] Example:

[0030] like Figures 1-4 As shown, this utility model provides a temporary support device for heavy objects, which includes: a support 10, a conical support bucket 20, and telescopic wheels 30;

[0031] The conical receiving bucket 20 is mounted on the bracket 10, and multiple telescopic wheels 30 are installed at the bottom of the bracket 10.

[0032] The telescopic wheel 30 includes: a cylindrical shell 31, a top flange cover 32, a bottom flange cover 33, a piston 34, a spring 35, and a caster wheel 36;

[0033] The cylindrical shell 31 is welded to the bottom of the bracket 10. The two ends of the cylindrical shell 31 are respectively connected to the top flange cover 32 and the bottom flange cover 33. The piston 34 slides freely along the inner wall of the cylindrical shell 31. The spring 35 is installed between the piston 34 and the top flange cover 32 to provide downward elastic force for the piston 34. The universal wheel 36 is installed below the piston 34. The bottom flange cover 33 has a limiting hole 37 in the center. The diameter of the limiting hole 37 is smaller than the outer diameter of the piston 34 to prevent the piston 34 from coming out of the bottom of the cylindrical shell 31. The universal wheel 36 can extend out of the cylindrical shell 31 through the limiting hole 37.

[0034] like Figure 3 , Figure 4 As shown, the piston 34 is provided with a guide shaft 38 at the top, and the top flange cover 32 has a guide hole at the center. The guide shaft 38 extends to the outside of the cylinder shell 31 through the guide hole.

[0035] like Figure 3 As shown, the outer wall of the guide shaft 38 is provided with external threads. After the guide shaft 38 passes through the guide hole, it is threadedly connected to the nut 39. Adjusting the position of the nut 39 on the guide shaft 38 can finely adjust the length of the universal wheel 36 extending out of the cylinder shell 31, thereby finely adjusting the height of the receiving device. Furthermore, during the process of connecting the top flange cover 32 to the flange of the cylinder shell 31, pre-tightening the nut 39 can overcome the elastic force of the spring 35 and pre-press the top flange cover 32 onto the top of the cylinder shell 31, which facilitates the installation of the top flange cover 32.

[0036] like Figure 1 , Figure 2 As shown, the bracket 10 is provided with a base 11 and a mounting plate 12 that are parallel to each other. The base 11 is located at the bottom of the bracket 10, and the mounting plate 12 is located above the base 11.

[0037] like Figure 5 As shown, the mounting plate 12 has a support hole 13 in the center, which supports the conical receiving barrel 20 and improves the installation stability of the conical receiving barrel 20.

[0038] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the mounting plate 12 has first through holes 14 corresponding to the cylindrical shell 31 around its perimeter, and the base 11 has second through holes 15 corresponding to the cylindrical shell 31. The top end of the cylindrical shell 31 is welded into the first through hole 14, and the bottom end of the cylindrical shell 31 is welded into the second through hole 15.

[0039] like Figure 2 As shown, the bottom surface of the bottom flange cover 33 installed at the bottom end of the cylinder shell 31 is higher than the bottom surface of the base 11, so that when the caster wheel 36 is retracted into the cylinder shell 31, it is the base 11 that is in contact with the ground, rather than the bottom flange cover 33, to prevent the cylinder shell 31 from being broken at its weld due to force.

[0040] The elastic force of the spring 35 satisfies the following conditions: when the receiving device is unloaded, the caster wheel 36 extends out of the cylinder shell 31; when the caster wheel 36 is completely retracted into the cylinder shell 31, the pressure on the caster wheel 36 is lower than its rated bearing pressure, thus preventing the caster wheel 36 from being crushed.

[0041] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0042] In this embodiment of the utility model, the receiving device can be conveniently moved under the heavy object by the universal wheel 36, and the conical receiving bucket 20 can effectively support heavy objects of various shapes. When the weight of the heavy object is too heavy, the universal wheel 30 retracts into the cylindrical shell 31, and the base 11 directly contacts the ground to prevent the universal wheel 30 from being crushed. It can effectively support heavy objects of various shapes and weights, and is highly versatile and convenient to use.
