Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, and in particular to an operating basket for truss docking or welding. Background Technology

[0002] Truss: A structure consisting of members connected to each other at both ends by hinges. A truss is a planar or spatial structure composed of straight members, generally with triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material, reduce self-weight, and increase stiffness compared to solid beams.

[0003] In large and above steel structure buildings, the trusses used are basically constructed from circular pipes of various diameters. In scenarios with large spans, truss connections are required. Therefore, a working platform needs to be provided for construction workers at the connection points. This working platform is generally a hanging basket, which is fixed to the truss by hoisting. Because it is constructed from circular pipes, and the hanging basket is generally constructed from common construction materials such as angle steel, I-beams, and channel steel, the contact area between the circular pipes and the hanging basket is relatively small during installation. If the reinforcement force is insufficient, the hanging basket is prone to swaying; if the reinforcement force is excessive, it can easily damage the circular pipes. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses an operating basket for truss docking or welding, comprising a basket body, a crossbeam fixedly connected to the upper end of the basket body, and side plates fixedly connected to both sides of the crossbeam. Each side plate has several slots, each slot accommodating a first clamping roller and a second clamping roller. The first and second clamping rollers have identical structures and are tapered from both sides towards the center. A first support block is fixedly connected to the side plate, supporting the end of the first clamping roller upwards. A second support block is slidably disposed on the side plate, supporting the second clamping roller upwards. A fixing block is fixedly connected to the lower part of the side plate, and an adjusting bolt is vertically threaded onto the fixing block, with the upper end of the adjusting bolt abutting against the lower end of the second support block. When using the hanging basket, it is hoisted onto the truss. First, the first clamping roller contacts the truss. Then, personnel enter the hanging basket and install the second clamping roller on the side plate. By tightening the adjusting bolts, the first and second clamping rollers are tightly clamped to the column truss, minimizing the hanging basket's swaying around the truss axis. Note that during the installation of the second clamping roller, it is necessary to determine and adjust the hanging basket's posture to ensure it is vertical.

[0005] Preferably, a safety rope binding rod is fixedly connected to the upper side wall of the side plate. During operation, the operator's safety rope is fixed to the safety rope binding rod, improving the safety of the operation.

[0006] Preferably, lifting lugs are fixedly connected to both sides of the upper end of the crossbeam. The lifting lugs facilitate the connection of the transport equipment, allowing the hanging basket to be moved to the required area.

[0007] Preferably, the basket comprises two mirror-shaped half-baskets, both of which are fixedly connected to a crossbeam, and an intermediate connecting plate is provided between the two half-baskets. During transport, the intermediate connecting plate is not installed. When transporting and placing the basket, the truss passes between the two half-baskets and contacts the first clamping roller. The intermediate connecting plate is installed after the second clamping roller is installed, or alternatively, the intermediate connecting plate can be installed first and then the second clamping roller. The intermediate connecting plate improves the safety of the hanging basket operation and facilitates its hoisting.

[0008] Preferably, the semi-basket includes a frame, with protective netting fixedly connected to three sides of the frame and a base plate fixedly connected to the bottom of the frame. That is, the top and sides of the frame are not sealed.

[0009] Preferably, the frame is constructed from several angle steels, and the basket's length, width, and height are 2.5m, 1m, and 1.5m respectively. This arrangement is to meet the needs of the operation.

[0010] The beneficial effects of this utility model are as follows: It is provided with a first clamping roller and a second clamping roller, which are fixedly connected to the circular tube by clamping. The structure of the first clamping roller and the second clamping roller has a large contact area with the circular tube, which not only can it clamp stably, but also minimizes damage to the circular tube.

Detailed Implementation

[0013] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0014] like Figures 1 to 4 As shown, an operating basket for truss docking or welding includes a basket body. A crossbeam 3, which is a U-shaped member, is fixedly connected to the upper end of the basket body in an inverted manner. Side plates 6 are fixedly connected to both sides of the crossbeam 3. Each side plate 6 has several slots, each accommodating a first clamping roller 4 and a second clamping roller 7. When in use, the basket is mounted on the truss. In large steel structure buildings, trusses are generally constructed using round tubular components; therefore, the first clamping roller 4 and the second clamping roller 7 achieve stable installation of the basket through clamping.

[0015] The first clamping roller 4 and the second clamping roller 7 have the same structure, and are tapered from both sides towards the center. This tapering increases the contact area between the first clamping roller 4, the second clamping roller 7, and the cylindrical component, thereby improving clamping stability. Furthermore, the first clamping roller 4, the second clamping roller 7, and the cylindrical component maintain flexible contact; that is, flexible materials, such as rubber sleeves, are applied to the surfaces of the first clamping roller 4 and the second clamping roller 7. A first support block 5 is fixedly connected to the side plate 6, supporting the end of the first clamping roller 4. Fixing bolts are inserted on both sides of the first support block 5 and are fixedly connected to the side plate 6. While the fixing bolts are not shown in the figure, the holes reserved for their installation are shown. A second support block 12 is slidably mounted on the side plate 6. Similarly, the second... The support block is located in the slot on the side plate 6. The second support block 12 supports the second clamping roller 7 upward. The upper end face of the first support block 5 and the second support block 12 are both semi-circular slots. The lower part of the side plate 6 is fixedly connected to the fixing block 10. The fixing block 10 is U-shaped, and fixing bolts are inserted on both sides of the fixing block 10. The fixing bolts are not shown here. The figure shows that there are slots for installing fixing bolts. The fixing block 10 is vertically threaded with the adjusting bolt 11. The upper end of the adjusting bolt 11 abuts against the lower end of the second support block 12. By tightening the adjusting bolt 11, the adjusting bolt 11 pushes against the second support block 12 and slides upward, that is, the second clamping roller 7 moves upward, and cooperates with the first clamping roller 4 to clamp the truss, thereby improving the stability of the hanging basket after installation and improving the safety of operation.

[0016] A safety rope binding rod 9 is fixedly connected to the upper side wall of side panel 6. When personnel are working in the hanging basket, they need to secure the fall protection safety rope to the safety rope binding rod 9 to ensure the safety of the operation.

[0017] Lifting lugs 8 are fixedly connected to both sides of the upper end of the crossbeam 3. The upper end of the lifting lug 8 is provided with a through hole for insertion, which facilitates the connection with the hoisting equipment and thus facilitates the assembly and disassembly of the hanging basket.

[0018] The basket consists of two mirror-shaped half-baskets 1, both of which are fixedly connected to a crossbeam 3. Specifically, the lower ends of both sides of the crossbeam 3 are welded to the half-baskets 1. An intermediate connecting plate 2 is provided between the two half-baskets 1. During installation, the truss's circular tubular components are positioned between the two half-baskets 1, and the basket is placed on these components from top to bottom. After placement, the intermediate connecting plate 2 is installed, fixing the lower parts of the two half-baskets 1 together, thus improving the structural strength and operational safety of the basket.

[0019] The half-basket 1 includes a frame 101, with protective netting 102 fixedly connected to three sides of the frame 101, and a base plate 103 fixedly connected to the bottom of the frame 101. That is, the upper surface and one side of the frame 101 are not shielded, and when two half-baskets 1 are joined together, the two sides are positioned opposite each other. The protective netting 102 and the base plate 103 are provided to improve operational safety. It should be noted that the protective netting 102, the base plate 103, and the intermediate connecting plate 2 are all fixedly connected to the frame 101 using screws or bolts.

[0020] Frame 101 is constructed from several angle steel bars, and the basket's length, width, and height are 2.5m, 1m, and 1.5m respectively. These dimensions are designed to meet operational needs while facilitating hoisting.

[0021] During installation, the hoisting setup is connected via the lifting lugs 8, and the hanging basket is moved onto the round pipe fitting, so that the first clamping roller 4 is mounted on the round pipe fitting. Then, the second clamping roller 7 is installed, that is, the second clamping roller 7 is placed in the slot, and the fixing block 10 and other components are installed at the lower part of the slot. Then, the adjusting bolt 11 is tightened to push the second clamping roller 7 to move upward, which works with the first clamping roller 4 to clamp and fix the round pipe fitting. Finally, the intermediate connecting plate 2 is fixedly connected between the two half-baskets 1 to complete the installation of the hanging basket.
