Description

A substation cabinet installation trolley

technical field

The utility model relates to the field of transport tools, in particular to a hand pushing frame for installing cabinets in substations.

Background technique

Due to the large weight of the cabinets such as power distribution cabinets and protection cabinets in substations and switching stations, usually up to 800-2000Kg, the display cabinets in substations are generally placed in a horizontal and close arrangement, and form a row of screen cabinets. The operation aisle is reserved between them, so the method of loading and unloading the screen cabinet needs to be extracted. When moving and installing the cabinet in the substation, it takes 8 to 10 people to work together to move the cabinet. When the cabinet is placed on the cable interlayer or above the cable trench It is because the installation is labor-intensive and inconvenient due to the narrow location. Every time the cabinet is installed or replaced, the construction is time-consuming, laborious and inconvenient due to moving in and out of the cabinet and transportation, and even the equipment in the cabinet is damaged due to bumping, resulting in a large number of Economic losses.

The Chinese patent with the authorized announcement number CN 204452498 U discloses a mobile trolley for a substation screen cabinet. The mobile trolley includes a main vehicle and an auxiliary vehicle. The auxiliary vehicle is a pallet with rollers at the bottom. The main vehicle is provided with two side rails. Supporting beams, one ends of the two side supporting beams are fixed to both ends of the base beam through laterally rotating rotating shafts, universal wheels are fixed on the other end of the side supporting beams and the bottom surfaces of the two ends of the base beam, and the base Handrails are fixed on the crossbeam through columns, and a support plate is fixed on the base crossbeam, and the support plate is controlled by a lifting mechanism to move up and down in the vertical direction. The substation screen cabinet mobile trolley saves a lot of manpower, material resources, and financial resources, improves work efficiency, ensures the rapidity and safety of replacing the screen cabinet, and has a significant social effect. However, the mobile trolley of the substation screen cabinet of the utility model will tilt the cabinet body to be transported during use, which is easy to cause damage to the equipment inside the cabinet body, and is not suitable for operation across cable trenches or cable interlayers.

The Chinese patent with the application publication number of CN 104444877 A discloses a simple heavy object handling vehicle, which includes a base, universal casters arranged on the four feet of the base, a bracket fixed as one with the base, and a bracket that is located on the top of the bracket and can The sliding bracket that slides back and forth on the bracket, the manual winch fixed at the rear of the sliding bracket, the pulley block and the lifting hook installed at the front of the sliding bracket, the pulley block includes a fixed pulley and a movable pulley, and a steel wire rope is drawn from the manual winch. After bypassing the fixed pulley and movable pulley in turn, it is fixed on the sliding bracket or the fixed pulley bracket, and the lifting hook is connected with the movable pulley; a fixed pallet is installed at the rear of the base, and a movable pallet is installed at the front, and the movable pallet Hinged with fixed pallet. The invention uses a simple structure to realize the dual functions of lifting and transferring heavy objects, and reduces the labor intensity of workers; meanwhile, the invention has simple structure, convenient operation, and low cost, and meets the needs of small and medium-sized enterprises. However, when loading and unloading the simple and easy heavy object carrier of this invention, because the center of gravity is not in the middle, especially when the center of gravity of the object is high, it is very unstable, and it is very likely to topple over, causing serious economic losses. In addition, the invention Not suitable for operation across cable trenches or cable sandwiches.
