Abstract
The invention provides an automatic transition board folding and unfolding device for an automobile. The automatic transition board folding and unfolding device comprises a motor arranged on an automobile body, an output shaft of the motor is connected with a worm gear case through a coupler, a worm gear output shaft of the worm gear case is provided with a bevel gear which is matched with a gear arranged on a rotating shaft to drive transition boards on the rotating shaft to rotate. The automatic transition board folding and unfolding device for the automobile has the advantages of being simple in structure, convenient to use and large in weight capacity, causing small damage to a road surface when in use and guaranteeing that the two transition boards rotate and unfold synchronously.
Description
Technical field
The present invention relates to a kind of automobile cab apron automatic retraction device.
Background technology
Along with the fast development of China Logistics industry, transport service is especially convenient, flexibly flat car means of transportation quickly grow, the recoverable amount of flat car also increases quickly.In the current marketplace, in addition to the flat car being specifically designed to Container Transport, it is simply that for transporting the flat car of various engineering machinery.For meeting the needs of various engineering machinery getting on-off automobile flat board, it is designed with two cab aprons at automobile flat plate afterbody.
Owing to engineering machinery self is heavier, and it mostly is the crawler type method of operation, carrying gravity, hardness and the toughness of cab apron is desirable that higher.And existing flat car cab apron cannot be applicable to some heavy or superduty engineering machinery.
And existing cab apron inertia during packing up and putting down is relatively big, when cab apron link can be built and uses, road pavement damage in various degree all will not can be caused.Simultaneously the most once two cab apron motions are inconsistent may bring potential safety hazard to the engineering machinery of upper and lower dollie.
The content of invention:
The present invention is contemplated to make up deficiency of the prior art, it is provided that a kind of simple in construction, easy to use, bearing capacity big, when using road pavement damage little, and can ensure that the automobile cab apron automatic retraction device that two cab apron synchronous axial system stretch.
To achieve these goals, the present invention provides techniques below scheme:
Automobile cab apron automatic retraction device, it includes: be respectively provided on two sides with connection seat at car body, it is respectively equipped with short rotating shaft in connecting seat, short rotating shaft is connected with cab apron respectively, it is characterized in that: two described short rotating shafts are merged into a rotating shaft and run through in the connection seat being connected to car body both sides, are provided with the first bevel gear at the middle part of rotating shaft；Being provided with motor on car body, the output shaft of motor is connected with the worm screw in worm gear case by shaft coupling, is provided with the second bevel gear matched with described first bevel gear on the worm-gear output shaft of worm gear case.
On the basis of technique scheme, it is also possible to have a technical scheme further below:
In the rotating shaft of the both sides of each cab apron, it is arranged with a connection seat being connected with car body respectively.
Be hinged with two grades of cab aprons in one end of described cab apron, the other end at two grades of cab aprons is provided with guide wheel.
The width of two grades of described cab aprons is less than cab apron, is arranged with supporting leg on cab apron.
It is an advantage of the current invention that:
The present invention have simple in construction, easy to use, load capacity is big, when using road pavement damage little, and can ensure that the advantages such as two cab apron synchronous axial system stretching, extensions.
Accompanying drawing illustrates:
Fig. 1 is the front view of the present invention；
Fig. 2 is cab apron schematic diagram when packing up；
Fig. 3 is the A direction view in Fig. 2.
Detailed description of the invention:
As shown in Figure 1, car cab apron automatic retraction device, it includes: arrange a rotating shaft 5, the first bevel gear 5a it is arranged with at the middle part of rotating shaft 5, on the position at rotating shaft 5 two ends, it is respectively provided with a cab apron 6, and two cab aprons are for being symmetrical arranged, the rotating shaft 5 of each cab apron 6 both sides is arranged with a connection seat 7 being connected with car body respectively.
Car body is provided with motor 2, the output shaft 2a of motor 2 is connected with the worm screw 3a in worm gear case 3 by shaft coupling 1, and form power transmission cooperation, and the worm gear 3b in worm gear case 3 is arranged with worm-gear output shaft 4, worm-gear output shaft 4 is provided with a second bevel gear 4a matched with the first bevel gear 5a.
As shown in Figure 2, motor 2 and worm gear case 3 are arranged on the inside of car body 8 by pedestal 8a, the output shaft 2a of motor 2 forms power transmission by shaft coupling 1 and coordinates with worm gear case 3, and the second bevel gear 4a on the worm-gear output shaft 4 of worm gear case 3 and the first bevel gear 5a in rotating shaft 5 is meshed and forms power conduction.Rotating shaft 5 is driven to rotate, owing to rotating shaft 5 is a bearing by first and second bevel gear, it is possible to guarantee two cab apron 6 synchronous axial system all the time being symmetricly set in rotating shaft 5.Rotating shaft 5 is connected on the end face of car body 8 afterbody by connecting seat 7.
The most hinged two grades of cab apron 6a in one end of two described cab aprons 6, the other end at two grades of cab apron 6a connects the diameter guide wheel 6b more than two grades of cab apron thickness by support 9, guide wheel 6b thus can be made first to contact with ground, by guide wheel rolling on the ground excessive, it is to avoid the rigid contact on two grades of cab aprons and ground.
As it is shown on figure 3, the width of two grades of cab apron 6a is less than cab apron 6, and on the cab apron 6 of pin joint, it is arranged with a pair supporting leg 6c two grades of cab apron 6a both sides, as in figure 2 it is shown, the thickness that the height of supporting leg 6c is more than two grades of cab apron 6a.So would not encounter supporting leg when two grades of cab aprons are packed up, height while ensureing oneself intensity, can effectively play again the effect supporting I and II cab apron more than the supporting leg of two grades of cab apron thickness.
