Ground four rail friction-type travel lines
Technical field
The utility model belongs to the conveying technology field, relates in particular to a kind of long-pending ground of putting and turning four rail friction-type travel lines when being used for the high center of gravity workpiece and carrying.
Background technology
Ground friction formula conveyer is used for the motor plant delivery system more.Common ground friction formula conveyer is a double-rail track, track had both been born the walking of car group, also serve as chassis and set upright rail, when carrying general automobile body-in-white or paint vehicle body (in the high about 1500mm of workpiece), because the vehicle body center of gravity is lower, unbalance loading is not obvious, carry more steady, but when carrying the higher workpiece of center of gravity (as utility van or commercial vehicle etc.), because center of gravity is higher, unbalance loading is obvious, can cause vehicle body to lopsidedness during conveying, thereby causing car group and track one lateral deviation to be carried causing severe wear to influence equipment starts rate and service life, brings bigger loss to main engine plants.
The utility model content
The purpose of this utility model is to provide a kind of ground four rail friction-type travel lines, and it can realize the conveying of high center of gravity workpiece steadily, and there is unbalance loading in ground friction formula travel line conveying high center of gravity workpiece, carries jiggly problem in the prior art to solve.
For reaching this purpose, the utility model by the following technical solutions:
A kind of ground four rail friction-type travel lines, it comprises that carrying chassis, friction drive unit, car group walking track, friction connecting rod, track are drawn together frame, chassis is set upright track and chassis righting wheel, described friction drive unit and car group walking track all are loaded on track and draw together on the frame, described chassis is set upright the track that track is installed on car group walking track top and is drawn together on the frame, described chassis righting wheel is installed on the carrying chassis and cooperates chassis to set upright the track setting, described friction connecting rod is connected with the carrying chassis, and on the described friction connecting rod dolly is installed.
Especially, described friction connecting rod is divided into three sections, is respectively front rod, intermediate connecting rod and rear linking rod, and dolly before installing on the described front rod is installed the back dolly on the described rear linking rod, dolly in the middle of installing on the described intermediate connecting rod.
Especially, described chassis righting wheel is set to four.
The beneficial effects of the utility model are, compared with prior art described ground four rail friction-type travel lines change four rail tracks into by original double-rail track, increase both sides and set upright track and be used for righting wheel walking on the chassis.Secondly, increase by four righting wheels on the chassis, be used to set upright on the rail and walk, guarantee the balance of high center of gravity workpiece, for the conveying of high center of gravity auto bodys such as auto trade such as little car, commercial vehicle and full-scale SUV provides a kind of later-model mode of movement.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
See also Fig. 1 to shown in Figure 3, in the present embodiment, a kind of ground four rail friction-type travel lines comprise that track draws together frame 1, described track is drawn together friction drive unit 2 and car group walking track 3 is installed on the frame 1, and described track is drawn together on the frame 1 and in the top of car group walking track 3 chassis to be installed and to set upright track 4, cooperate described chassis to set upright track 4 and be provided with four chassis righting wheels 5, described chassis righting wheel 5 is installed on the carrying chassis 6, on the described carrying chassis 6 the friction connecting rod is installed, described friction connecting rod is divided into three sections, be respectively front rod 7, intermediate connecting rod 8 and rear linking rod 9, dolly 10 before installing on the described front rod 7, back dolly 11 is installed on the described rear linking rod 9, dolly 12 in the middle of installing on the described intermediate connecting rod 8, chassis righting wheel 5 utilizes the tractive force of friction connecting rod to walk in chassis and sets upright on the track 4, and the single face of friction drive unit 2 direct drives friction connecting rod is to provide power.
Above-mentioned ground four rail friction-type travel lines provide a kind of later-model mode of movement for the conveying of high center of gravity auto bodys such as auto trade such as little car, commercial vehicle and full-scale SUV, and chassis is set upright track 4 and is used for righting wheel 5 walkings on the chassis.Secondly, increase righting wheel 5 on the chassis on the chassis, be used to set upright on the rail and walk, guarantee the balance of high center of gravity workpiece.
Above embodiment has just set forth groundwork of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
