Abstract

The utility model relates to a storage and transport truck in the industry of rubber-plastic manufactured article. One end of a sweep is linked to an extension rod pipe, and one end of the sweep is hinged on a frame by spindle noses on the two ends of the extension rod pipe and a tight setting axle. A metal wresting spring is penetrated in the extension rod pipe, the wresting spring generates one torque which is reversed to the torque generated by the self weight of the sweep. When the torque generated by the self weight of the sweep is bigger than the reverse torque generated by the wresting spring, the sweep is set flatly, and the sweep is raised to a certain angle. When the torque generated by the self weight of the sweep is smaller than the reversal torque of the wresting spring, the sweep is automatically turned up. The frame can be hinged with multilayer sweeps. The utility model has the advantages of portable sweep overturning, large storing quantity of rubber sheets and flexible carriage operation.

Description

Small-sized louver vehicle

The utility model relates to a kind of storage, transfer car(buggy) of product of rubber and plastic industry.

The rubber manufacturing technique requirent, the film after refining glue laminated system must can drop into next procedure, and film can not stack mutually in cooling process through the cooling and the resting period of certain hour, in order to avoid bonding.The producer of present rubber and plastic shoe-making industry deposits, transports film in the production process, all is to adopt Wooden tray or plastic pallet, by manually piling up the method that heap tires out and carries.Since each pallet to deposit the film amount little, use pallet to occupy a large amount of places in the workshop in a large number, and working strength of workers is bigger.

The purpose of this utility model is storage, the transfer car(buggy) that a kind of product of rubber and plastic industry will be provided.

The utility model purpose is achieved in that an end of metal sweep 2 is associated with extension bar pipe 3, is provided with the tightening axle 4 and the spindle nose 5 of through hole by extension bar pipe 3 two ends, is hinged on the vehicle frame 1 by bolt 22 and 16 ends with sweep 2.Being provided with one at an end of extension bar pipe 3 has U type groove and is fixed in fixed cover 6 in the extension bar pipe, be installed with the one one end hook other end in the extension bar pipe 3 and curve the straight-bar metal torsion spring 7 of rectangular-shaped cross section for circle, one end of torsion spring 7 hooks inserts in the U type groove of fixed cover 6, torsion spring 7 is reversed pretension around its axis, pass clip 8 by the other end that curves the right angle, pass the end that clip and the tightening axle shaft shoulder will curve the right angle by bolt 22 and be fixed on the vehicle frame 1.On vehicle frame 1, be provided with the through hole 15 and 9 that cooperates with spindle nose 5 and tightening axle 4.The periphery of the through hole 9 that cooperates with the tightening axle on the vehicle frame edge is provided with three female through holes 10.Sweep 2 is surrounded by strut 19 perpendicular to the both sides of extension bar pipe 3, is with on the strut to subtract to dash cover 20.On the shaft shoulder of tightening axle 4 and spindle nose 5, have a U-shaped gap.Be hinged with two-layer above multilayer sweep on the vehicle frame.When starting sweep 2 at an angle the time, sweep is upwards dug automatically.

The utility model is owing to adopted multilayer sweep and sweep switching mechanism, so increased the amount of storage of film, and the sweep interlayer has certain space, can make film obtain good cooling, it integrates deposits, transports, and the sweep upset is light, and dolly goes slick, alleviate working strength of workers, saved the production site in workshop.The dolly long service life, maintaining is easy.

Be described in detail below in conjunction with most preferred embodiment of the present utility model and accompanying drawing.

As shown in Figure 1, 2, it is main wheel that wheel adopts two directional wheels 11, and two cardan wheels 12 are wheel flutter.Vehicle frame 1 and chassis 13 adopt the shaped steel welding to make.Sweep 2 usefulness zinc coated sheets fold and form.One end of sweep 2 is associated in by rivet 21 on the extension bar pipe made from common steel tube 3, is provided with the tightening axle 4 and the spindle nose 5 of through hole by extension bar pipe 3 two ends, is hinged on the vehicle frame 1 by through hole on the vehicle frame 19 and 15 ends with the metal sweep.Tightening axle and spindle nose and vehicle frame hole cooperate and with the extension bar pipe cooperate the employing running-fit.The material of tightening axle 4 and spindle nose 5 is A ₃Steel has the gap of U-shaped on the shaft shoulder of tightening axle and spindle nose, bolt passes gap tightening axle and spindle nose are fixed on the vehicle frame.End in the extension bar pipe is provided with a fixed cover 6 that U type groove arranged, and the fixed cover plug welding is in the extension bar pipe.In the extension bar pipe, be installed with the one one end hook other end and curve rectangular-shaped cross section for justifying straight-bar metal torsion spring 7.One end of hook is inserted in the U type groove of fixed cover 6, apply an external force at an end that curves the right angle, make the right angle end oppositely rotate an angle around the torsion spring axis along the moment of torsion that the sweep deadweight produces, and when the moment of torsion that external force applies torsion spring does not surpass the elastic limit of torsion spring, by being enclosed within the clip 8 on the right angle end, the shaft shoulder that is passed clip and tightening axle by bolt is fixed on the end that torsion spring curves the right angle on the vehicle frame 1.At this moment torsion spring just produces a moment of torsion to sweep.The big I of moment of torsion is regulated by material and three tapped bore 10 of torsion spring 7.When the moment of torsion that deadweight produced of sweep during greater than the reactive torque of torsion spring, sweep can be set level, and when starting sweep to certain angle, the moment of torsion that the sweep deadweight produces is during less than the reactive torque of torsion spring, and sweep just can be dug automatically.Sweep that can this structure of hinged multilayer on vehicle frame.For avoiding the excessive and moment of torsion of interlamellar spacing to concentrate, torsion spring 7 inserts from the both sides of vehicle frame 1 are staggered respectively.As shown in Figure 1, on the both sides perpendicular to the extension bar pipe of sweep, be surrounded by two struts 19, adopt spot welding between strut and the sweep, on strut, be with to subtract and dash cover 20.13 first line of a couplet jugs 14 on the chassis.On vehicle frame, be welded with positioning plate 17, limiting stopper 18 is housed on the positioning plate.
