Description

Technical Field

[0001] This utility model belongs to the field of manned suspended platforms, and specifically relates to a rigidly connected manned suspended platform for cranes. Background Technology

[0002] In many fields such as building construction, bridge construction and maintenance, and large equipment installation, working at height is a common and indispensable part of the work. To ensure that workers can complete high-altitude tasks safely and efficiently, the crane-mounted personnel basket method is widely used. Traditional crane-mounted personnel baskets mostly use flexible connection methods, such as connecting the basket to the crane with ropes and chains. During operation, due to factors such as wind force and the crane's inertia, the basket is prone to swaying, which not only affects the stability of the workers' operation but also poses significant safety hazards.

[0003] Furthermore, some traditional manned suspended platforms have inadequate structural designs, with insufficient strength in the main frame, making them unable to withstand large loads. Under prolonged use or heavy loads, they are prone to structural deformation or even damage. Moreover, their protective measures for the manned platform are relatively weak, with poor anti-slip performance, insufficient height or inadequate stability of the surrounding guardrails, failing to provide comprehensive and reliable safety protection for workers and failing to meet the growing demands for safety and efficiency in high-altitude operations. Therefore, developing a crane-mounted manned suspended platform with stable connections, high structural strength, and good safety performance is of significant practical importance. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a rigid connection for a crane to carry a person-carrying basket, which uses the locking lugs of the crane's auxiliary boom and main boom as connection points to lock the person-carrying platform in that position, thus completing the basket fixation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A rigid connection manned cradle for a crane includes a V-shaped bracket. One end of the V-shaped bracket is provided with a pin for fixing the crane's auxiliary boom lug. The V-shaped bracket, together with the horizontal bracket and the vertical bracket, forms the main frame, on which the manned platform is installed.

[0007] Preferably, there are two V-shaped brackets, with the number of horizontal brackets corresponding to the number of V-shaped brackets; the vertical brackets are used to connect the V-shaped brackets and the horizontal brackets.

[0008] Preferably, a number of reinforcing ribs are welded between the two V-shaped bracket profiles.

[0009] Preferably, one end of the V-shaped bracket has a pin hole and a pin for fixing the crane's auxiliary boom lug at the pin hole.

[0010] Preferably, the manned platform is welded to the main frame.

[0011] Preferably, the manned platform is in an inclined state.

[0012] Preferably, the manned platform has an outer frame made of angle steel, a guardrail made of round steel on all sides, and a bottom enclosure made of patterned steel plate.

[0013] The present invention can achieve the following beneficial effects:

[0014] 1. The rigid connection of the personnel basket of this crane is composed of V-shaped brackets, horizontal brackets and vertical brackets to form the main frame. The V-shaped brackets are made of two channel steels bent and welded with reinforcing ribs. The horizontal brackets are manufactured on the same principle. This design greatly enhances the stability and strength of the overall structure, can withstand large loads, ensures the stability of the basket when working at height, and reduces the safety risks caused by structural instability.

[0015] 2. The suspended platform is equipped with a locking pin for fixing the crane's auxiliary boom lug at one end. Before use, simply extend the crane boom and adjust the elevation angle to the lowest point to quickly lock it with the lug hole at the front end of the crane boom. The operation is simple and easy to understand, which greatly shortens the installation time and improves the efficiency of work preparation. It is suitable for various emergency or routine high-altitude work scenarios.

[0016] 3. The manned platform is welded to the main frame and is tilted, which effectively prevents personnel and tools from accidentally slipping due to shaking. It uses angle steel as the outer frame, round steel as guardrails on all sides, and checkered steel plate to close the bottom. This not only ensures the platform's sturdiness, but also provides good anti-slip and protective functions, ensuring the personal safety of workers when working at heights in all aspects.

[0022] Preferred solutions include Figures 1 to 3As shown, a rigidly connected personnel-carrying basket for a crane includes a V-shaped bracket 1. One end of the V-shaped bracket 1 is equipped with a pin 2 for fixing the crane's auxiliary boom. The V-shaped bracket 1, together with a horizontal bracket 4 and a vertical bracket 5, forms the main frame. A personnel-carrying platform 3 is mounted on the main frame. Specifically, the personnel-carrying platform 3 is welded to the main frame. The personnel-carrying platform 3 is in an inclined state. The personnel-carrying platform 3 has an outer frame made of angle steel, a guardrail made of round steel on all sides, and a closed bottom made of checkered steel plate.

[0023] Before use, extend the crane boom and adjust the elevation angle to the lowest possible position. Then, lock the personnel basket to the lifting lug at the front of the crane boom by inserting the pin. Move the crane to the desired location and raise the boom to the designated position.

[0024] The V-shaped support 1 is made of two bent channel steels with reinforcing ribs 6 welded between them. The horizontal support 4 is made in the same way as the V-shaped support 1. The passenger platform 3 is framed with angle steel, and the surrounding guardrails have ribbed steel bars. The bottom passenger platform is enclosed with patterned steel plates.

[0025] The working principle of this device is as follows:

[0026] like Figure 1-3 As shown, after the personnel basket is connected and fixed to the crane, the personnel stand in the basket and fasten their safety belts. The crane positions itself at the location of use, extends its boom to send the basket to the designated position, and the personnel can then begin high-energy, high-altitude operations.
