Abstract

The utility model relates to an engineering vehicle coupled directly to a tractor. An integral cable winder device is composed of a supporting bracket, a cable winder and a bearing seat. The cable winder device is fixed on edge beams on both sides of the front end of a tractor by the edge beams on both sides of the supporting bracket. A double-face coupling flange on a generator is respectively in rabbet positioning connection with the housing of the generator and a rabbet positioning bearing seat inside a towing device on the back end of the gearbox of the tractor. A spline or a single key on the shaft head of the generator is directly connected with the splined hole of the power output shaft of a back housing. The utility model has the advantages of simple structure, easy assemblage, convenient moving, low cost and high work efficiency. The utility model conforms to the requirement of regular design for electromechanical products.

Description

Electricity generating vehicle coupled directly to tractor

The utility model relates to a kind of portable electrical source of power or welding source that is used for open work, particularly a kind of trac. associated mode generation engineering car.

At present, the generator set that uses in the open-air open work operation, basically utilize electrical generator and coupler, speed-change gear box, combustion engine to be connected in series on the same frame, carry out the direct connection transmission, or with the power spindle nose laid parallel of electrical generator and combustion engine, be installed in parallel on same frame, carry out belt-driving.This generator set divides fixed type or towed two kinds, needs special-use vehicle to transport dress or traction.

Nearest engineering generator car of producing by the trial-production of minority factory of forming by trac. and electrical generator, its structure is to utilize the existing rearmounted power take-off shaft of trac., by being connected in series, and be fixedly connected simultaneously on the Support bracket that below the gear box of tractor body, is connected as a single entity with raising speed gear case, coupler, electrical generator.Owing to be connected in series, cause the axial mounting structure size in trac. rear end obviously to extend, form the car body deformity, do not meet regular electronic product designing requirement.

The purpose of this utility model provides a kind of trac. associated mode generation engineering car, and it is simple in structure, and assembling meets the regular designing requirement of electronic product easily, has conveniently moving, and cost is low, the advantage that operating efficiency is high.

The purpose of this utility model is achieved in that this device comprises trac. that has the rearmounted power take-off shaft of spline cellular type and cable drum device, the electrical generator of assembling its front and back ends, the cable drum device of wherein being made of one Support bracket, cable drum, bearing seat utilizes Support bracket both sides side bar to be fixed on the side bar of trac. front end both sides; Two-sided mounting flange on the electrical generator respectively with generator housing, gear box of tractor body rear end draw gear in seam fix shaft bearing carry out seam location and connect; Generator shaft headdress flower key or singly-bound directly connect with the splined hole of rearmounted power take-off shaft.

Because it is trac. with novel traction device and the improved electrical generator that is provided with two-sided mounting flange of CN90219422.4 that the utility model adopts the patent No., the cable drum device that utilizes Support bracket both sides side bar to be fixed on the trac. front end assembles, so overcome the shortcoming that prior art exists, have simple in structurely, the cost cost is low, and total arrangement is reasonable, the driving efficiency height, assembling meets the advantage of the regular designing requirement of electronic product easily, is easy to apply.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the interior local structure cutaway view of frame of broken lines among Fig. 1.

12 is that the employing patent No. is the trac. of the novel transmission traction device of having of CN90219422.4 in the accompanying drawing, the cable drum device that its front end is fixedly connected and is made up of Support bracket 9, cable drum 10, bearing seat 11 3 parts.The both sides side bar is fixedly connected on the lengthening side bar of trac. 12 front end vehicle frame both sides on the Support bracket 9, and bearing seat 11 is fixedly connected on Support bracket 9 both sides side bars, and the both sides spindle nose of cable drum 10 utilizes bearing seat 11 to carry out support fixation.Gearbox body 1, seam fix shaft bearing 2, have link plate 3 behind the mounting flange, the rearmounted power take-off shaft 8 of spline cellular type is trac. 12 original design parts.Two-sided mounting flange front end cover 4 on the electrical generator 13 after the improvement, its right-hand member carries out the seam location with generator housing 6 and connects, position by stop portion A between left end and the seam fix shaft bearing 2, utilize bolt 7 to connect screw and carry out fastening connection by respective flange on the flange connection holes on the front end cover 4 and the back link plate 3.Generator shaft 5 left ends utilize bearing to be positioned on the front end cover 4, its left end spindle nose, be processed into spline and insert (or adopting singly-bound to connect) in output shaft 8 splined holes, because of reaching between seam fix shaft bearing 2 and the front end cover 4 between output shaft 8 and the seam fix shaft bearing 2 the right alignment technical requirements is arranged, thereby guaranteed generator shaft 5 and output shaft 8 castellated shafts and hole centering right alignment requirement in the fitting process.

Direct connecting generator of trac. 12 front and back ends of the present utility model and cable drum device, utilize the power driven of trac., as electrical source of power or welding source, do not need to join in addition special-use vehicle at the scene during operation and transport dress or traction, it provides generation engineering car easy to use for various open work operations.This device can be widely used in operation places such as municipal works, highway construction, capital construction, development of the field, bridge construction.
