Description

Technical Field

[0001] The utility model belongs to the technical field of safety facilities, and in particular relates to a safety device for high-altitude operation of a crane. Background Art

[0002] Safety in production is vital to the development of an enterprise. Safety is always an eternal theme, and safety in high-altitude operations is even more critical. The safety device for high-altitude operations of cranes is used when assembling the steel structure of the crane. During the assembly process of the lower cover plate and the л-shaped beam, the operator needs to be on the lower cover plate and command the crane to lift the steel ingot and press the cover plate down to ensure that the gap between the web plate and the lower cover plate is minimized, and the distance between the web plate and the edge of the cover plate is measured to ensure that the cover plate is centered. At the same time, high-altitude operations such as dragging the welding machine to fix the cover plate are performed to ensure the personal safety of the operator.

[0003] The safety device in the prior art often uses a safety bracket installed on the lower cover plate and connects the mounting brackets at both ends through a steel wire rope. The operator is connected to the steel wire rope through a safety rope for safety protection. When installing the safety device, since the workpiece base material cannot be spot welded at will, one person must pull the steel wire rope from one end to the other end. This installation process itself contains unsafe factors. In addition, the time to install the safety bracket exceeds the working time, and the disassembly is also quite cumbersome. It is also laborious to recycle the safety rope after use, and it is not convenient to recycle. Therefore, when workers perform this process, due to the lack of convenient safety facilities, they often choose not to take safety measures and complete the process quickly. This will lead to a fluke mentality and bring great safety hazards. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0028] like Figures 1 to 3 As shown, the crane aerial work safety device of the utility model comprises a first safety beam 1, a second safety beam 2, two support assemblies 3, two clamping assemblies 4, an adjustment kit 5 and a hook 6. The second safety beam 2 is vertically welded to the top of the first safety beam 1, the two support assemblies 3 are respectively arranged at the lower end of the first safety beam 1 and the lower end of the adjustment kit 5, the two clamping assemblies 4 are correspondingly arranged on one side of the first safety beam 1 and the adjustment kit 5, the adjustment kit 5 is adjustably sleeved on the first safety beam 1, and the hooks 6 are respectively arranged at the top of both ends of the first safety beam 1 and the top of the second safety beam 2, wherein:

[0029] The support assembly 3 includes a connecting plate 31 and a supporting wheel 32. The supporting wheel 32 is mounted on the connecting plate 31 through a hinge shaft, thereby effectively ensuring the installation of the supporting wheel 32. The supporting wheel 32 has a caster brake function.

[0030] The clamping assembly 4 includes a mounting beam 41 and a clamping wheel 42. The clamping wheel 42 is mounted on the mounting beam 41 through a hinge shaft, thereby effectively ensuring the installation of the clamping wheel 42.

[0031] The adjustment kit includes a slider 51 and an adjustment bolt 52 , and the slider 51 is fixed by the adjustment bolt 52 .

[0032] Furthermore, in the crane aerial work safety device of the utility model, one of the support components 3 is welded on the first safety beam 1 through a connecting plate 31 to correspond to the second safety beam 2, thereby effectively increasing the stability of the second safety beam 2;

[0033] Another supporting component 3 is welded to the front end of the sliding block 51 via a connecting plate 31, so that the supporting component 3 has adjustability.

[0034] Further, in the crane aerial work safety device of the utility model, one of the clamping assemblies 4 is welded to one end of the first safety beam 1 close to the second safety beam 2 through the mounting beam 41;

[0035] Another clamping assembly 4 is welded to the rear end of the slider 51 through the mounting beam 41, so that the clamping assembly 4 has adjustability.

[0036] Furthermore, in the crane aerial work safety device of the present invention, the support wheel 32 and the clamping wheel 42 are perpendicular to each other, thereby effectively ensuring that after the support wheel 32 abuts against the upper surface of the lower cover plate, the clamping wheel 42 can clamp the web, and at the same time the side surface contacts the lower surface of the lower cover plate, effectively ensuring the overall stability after installation.

[0037] Furthermore, in the crane aerial work safety device of the present invention, threaded holes 11 are arranged at one end of the first safety beam 1 away from the second safety beam 2, the slider 51 is sleeved on the first safety beam 1, and the adjusting bolt 52 passes through the slider 51 and engages with the threaded hole 11, so that the distance between the support wheels 32 at both ends and the distance between the clamping wheels 42 can be adjusted by adjusting the slider 51 on the first safety beam 1 to adapt to main beams and secondary beams of different sizes, thereby increasing the versatility and applicability of the device.

[0038] Specifically, during installation, first remove the adjusting bolt 52 and adjust the slider 51 to the maximum size. At this time, press the support wheel 32 on one side of the second safety beam 2 downward to abut against the upper surface of the lower cover plate, so that the support wheel 32 can roll along the upper surface of the lower cover plate, and at the same time drag the first safety beam 1 to make the clamping wheel 42 abut against the web plate, and roll along the web plate, and make the side surface of the clamping wheel 42 abut against the lower surface of the lower cover plate, so as to ensure that the clamping wheel 42 is effectively clamped. At this time, push the slider 51 toward the web plate until the clamping wheel 42 installed on the slider 51 abuts against the web plate, and fix the slider 51 to the first safety beam 1 by adjusting the bolt 52;

[0039] When in use, the support wheel 32 and the clamping wheel 42 are used to push the lower cover plate to the position to be processed and the caster brake function of the support wheel 32 is used to brake and fix it. During the pushing process, the operator needs to clamp the safety belt device on the hook 6 at the top of the second safety beam 2. When the operator needs to process the web, he only needs to clamp the safety belt device on the hook 6 at the top of both ends of the first safety beam 1 to operate.

[0040] In summary, compared with the prior art, the crane aerial work safety device of the utility model has the following advantages and beneficial effects:

[0041] The overall structure is simple and is connected to the lower cover through the cooperation of the support assembly and the clamping assembly. There is no need for welding and bolting, which makes it easy to install and disassemble and simple to operate. It can be adjusted by adjusting the adjustment kit and is suitable for main and secondary beams of various cross-sections, effectively saving construction time and ensuring construction safety.
