Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and in particular to an electrical panel cabinet transporting device in an electrical room of a crane. Background Art

[0002] Cranes working in harsh environments such as extreme ambient temperature, dust, salt spray, and heavy rain generally have an electrical room set up to ensure the normal operation of electrical equipment and extend its service life. The room is set up inside the box of the main beam or along the web of one side of the main beam. It is a long rectangular shape, with one or two rows of electrical equipment arranged indoors, and a maintenance passage is reserved. The panel cabinets in the electrical room include speed control devices, transformers, PLCs, distribution cabinets, etc. Each panel cabinet weighs between 100 and 400 kg. Due to the limited space in the electrical room, it is impossible to arrange lifting equipment. When installing and disassembling electrical panel cabinets, multiple people used to use auxiliary tools such as trolleys to put the panel cabinets in place, which was time-consuming, labor-intensive and unsafe. When adjusting the panel cabinets in place, the manpower is often less than the gravity moment of the panel cabinet flipping, causing the panel cabinet to tip over and be damaged or injure people. Summary of the invention

[0003] In view of the above technical problems that it is impossible to arrange lifting equipment when installing electrical equipment in the electrical room, and the installation of equipment is time-consuming, labor-intensive and unsafe, a crane electrical panel cabinet transfer device in the electrical room is provided. The present invention is designed to provide an electrical panel cabinet transfer device arranged in the electrical room, which can transfer heavier electrical equipment that cannot be lifted by multiple people in the electrical room to the installation position, or remove it from its working position and transfer it to the outside of the electrical room for maintenance or replacement. It is suitable for the narrow maintenance passage of the electrical room, and improves the convenience and safety of the installation and maintenance of the electrical panel cabinet.

[0004] The technical means adopted by the present invention are as follows:

[0005] An electrical panel cabinet transfer device in an electrical room of a crane comprises: a steel rail, a pulley, a vertical suspension lifting rope, a top rod, a tray, a horizontal guide rod, and a support rod;

[0006] The steel rail is installed on the top of the electrical room along the length direction of the electrical room and connected to the electrical room load-bearing frame; the pulley and the support rod form a pulley device and can be transported on the rail;

[0007] The vertical suspension lifting rope is used to adjust the height of the pallet and the inclination angle of the horizontal guide rod, and is composed of a lock turn buckle and a connecting rod or a sling; the top rod is used to ensure the balance of the device when loading into the cabinet; the pallet is used to load the electrical cabinet, and two or more horizontal guide rods are fixed on the upper surface of the pallet chassis;

[0008] The horizontal guide rod is composed of a metal rod with a smooth surface. The angle between the horizontal plane and the horizontal plane is adjusted by vertically suspending lifting cables, and the gravity force of the electrical cabinet is used to assist the cabinet to slide. The nylon rope is used to bind the cabinet.

[0009] Furthermore, the pallet is a component made of metal material with fences on three sides.

[0010] Furthermore, the surface of the horizontal guide rod is smooth, and its inclination angle is adjusted by vertically suspending the lifting rope, so that the electrical panel cabinet can slide between the tray and the installation position with the help of human assistance by the gravity component.

[0011] Furthermore, four sets of double-wheel pulley devices are arranged at the four corners of the rectangular frame of the pulley, and the whole device can be transported on the track by manpower through the pulleys.

[0012] Furthermore, the nylon rope is used to tie the screen cabinet within the straight suspension lifting rope and the pallet.

[0013] Due to the adoption of the above technical solution, compared with the prior art, the present invention has the following advantages:

[0014] 1. The present invention provides an electrical panel cabinet transfer device in the electrical room of a crane. Compared with the traditional installation and disassembly of electrical panel cabinets which rely on manpower with the help of auxiliary tools such as trolleys, which has the risk of panel cabinet tipping over and being damaged or injuring people, the present transfer device achieves mechanized assisted disassembly and assembly, and translation of panel cabinets through the coordination of various components, such as vertically suspended lifting cables to adjust the height of the tray and the inclination angle of the horizontal guide rod, top rods to ensure balance, and nylon ropes to bind the panel cabinets, thereby avoiding the safety hazards caused by manual lifting and improving operational safety.

[0015] 2. The present invention provides an electrical panel cabinet transfer device in the electrical room of a crane. Compared with the traditional trolley that needs multiple people to push and climb over obstacles in the electrical room, and when there are irregular obstacles in the passage, the transportation efficiency is seriously affected and even the panel cabinet is overturned. The pulley device composed of the pulley and the support rod of the transfer device can be easily transferred on the track, and the horizontal guide rod can use the gravity component of the panel cabinet to assist in sliding, which adapts to the narrow space of the electrical room and effectively improves the transportation efficiency of the electrical panel cabinet.

[0016] Based on the above reasons, the present invention can be promoted in the field of crane technology. BRIEF DESCRIPTION OF THE DRAWINGS
