Abstract
The present invention relates to the technical field of electrical equipment, and especially relates to a driving device used for a busbar bending device. The driving device comprises a base plate, a tooth bar sliding block, a gear, a rotating shaft and a ratchet wheel; an upper end surface of the base plate is provided with a bearing support and a positioning groove; the tooth bar sliding block is installed in the positioning groove; the gear is positioned right above the tooth bar sliding block; gear teeth on the gear are cooperated with gear teeth on the tooth bar sliding block; the gear and the rotating shaft are connected via a key; the ratchet wheel and the gear are coaxially arranged; the ratchet wheel and the rotating shaft are connected via a key; and two ends of the rotating shaft are connected with the bearing support via bearings. Rotation is converted into rectilinear motion of the tooth bar sliding block by the ratchet wheel mechanism and the rack-and-pinion mechanism, compared with an original device, service lifetime is prolonged, and working efficiency is improved, thereby facilitating operation.
Description
Technical field
The present invention relates to technical field of electric equipment, is a kind of drive unit for bus bending device specifically.
Background technology
Bus refers to and to be used as in voltage switchgear between connecting cabinet and in cabinet, each electrical equipment carries out collecting, distribute and transmitting the conductor of electric energy.Will bear heating and electrodynamic action that short circuit current causes when being short-circuited fault, be as primary element important in the high and low pressure complete sets of electric switchgears and control devices.Switch cubicle bus is divided into by its cross section: rectangle, circle (or two D shape) and busbar channel 3 kinds.
When the cross-sectional area of bus is identical, the girth of rectangular bus bar is larger than circular busbar, its good heat dissipation effect, and cooling condition is good.And under certain permission heating-up temperature, the electric current that rectangular bus bar passes through is larger than circular busbar, the kelvin effect of circular busbar is comparatively strong, and rectangular bus bar is more even.Therefore generally all rectangular bus bar is adopted in voltage switchgear.
The material of bus is divided into copper, aluminium and steel, and the conductance of steel wherein copper is the highest, and when same cross-sectional is amassed, its current-carrying capacity is maximum; And steel is minimum, be usually used in PT loop or arrester loop.When many buses are arranged in juxtaposition use, its radiating condition is more very different than single.Open-type switch cubicle is larger than the busbar carrying capacity used in enclosed switchgear, and air-conditioned electric substation is air-conditioned better than not having.
The conductor that the duplexure that respectively dams in electric device is connected together by bus (busbar).It is the carrier collecting and distribute electric power, also known as bus rod.Traditionally the conductor of current-carrying duplexure in each power supply unit is all loosely referred to as bus.The effect of bus collects, distributes and transmit electric energy.Because bus is in operation, there is huge electric energy to pass through, during short circuit, subject very large heating and dynamo-electric effect, therefore, must reasonably select bus material, cross sectional shape and sectional area to meet the requirement of safety and economic operation.
In bus process, adopt the bender of specialty to carry out bending to bus, device structure is complicated, and cost is higher, for the processing enterprise that some are small-sized, provides production cost virtually, reduces the competitiveness of product in market.
Application number is: a Chinese patent of 201420505277.5 discloses a kind of easy bus bending device, comprise workbench, the side of described workbench is fixed with cover half, this workbench is also provided with chute, be provided with along slide and the dynamic model coordinated with cover half, workbench side is provided with the driving mechanism driving described dynamic model; The side of described workbench is provided with installing plate; described driving mechanism comprises fixing fixed block on a mounting board; fixed block is provided with tapped through hole; and be provided with through tapped through hole for driving the drive screw of dynamic model, the side of described cover half or dynamic model is provided with the detent mechanism determining bus bending position.This utility model structure is simple, and convenient operation, is placed on bus between fixed half and moving half, utilizes drive screw to advance dynamic model, realizes the bending operation of bus, Simple And Practical.The drive unit of this utility model realizes rectilinear motion by the mode of threaded engagement, because the force rate needed in the process of bending bus is larger, screw thread pair premature breakdown can be caused with screw-driven, reduce the service life of this device, and the pitch of screw-driven is less, need the longer time could realize a bending of bus, operating efficiency is lower.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of drive unit for bus bending device, service life and the operating efficiency of single unit system can be improved.
The technical solution adopted for the present invention to solve the technical problems is: a kind of drive unit for bus bending device, comprise base plate, rack slide, gear, rotating shaft and ratchet, described base plate upper surface is provided with two rolling bearing units and locating slot, in described locating slot, rack slide is installed, described gear is positioned at directly over rack slide, the gear teeth on gear match with the gear teeth on rack slide, be connected by key between gear with rotating shaft, described ratchet and gear coaxially arranged, be connected by key between ratchet with rotating shaft, rotating shaft two ends are connected with rolling bearing units respectively, ratchet is rotated by rotating shaft driven gear, the rectilinear motion of rack slide is realized by pinion and rack.
Described locating slot is dovetail groove.
Described ratchet is bidirectional ratchet, only need change the Impact direction of ratchet, can realize the reciprocating motion of rack slide.
Described ratchet is provided with demountable reinforcement bar.
The invention has the beneficial effects as follows: a kind of drive unit for bus bending device of the present invention, specific motion is realized by ratchet mechanism and pinion and rack, relative to traditional drive motion mode, improve service life, and gearratio of the present invention is larger, convenient operation, improves operating efficiency greatly.
