Description

Carrying chassis

Technical field

The utility model is related to the carrying chassis used in the carrying or keeping of goods, more particularly at the bottom of vehicle body Face has the carrying chassis of universal type wheel (castor).

Background technology

As shown in Fig. 2 in general, the carrying chassis 91 used in the carrying or keeping of goods possesses：With with ground The chassis 92 that the mode of face level is set；The multiple wheels 93,94 set in the lower end of the vehicle bodies such as the bottom surface on chassis 92；And root Supporting frame 96 and mounting platen 97 for being set according to size and purposes etc..

Moreover, the wheel on carrying chassis, it is known that being installed in the leading section of the lower end of vehicle body and rearward end Two pairs totally four wheel, and it is well known that there are several intermediate wheels in their centre according to purposes.

Wheel 93,94 includes the fixed wheel 94 that can only move in the longitudinal direction and can turned around vertical axle In the universal type wheel 93 for moving and being moved to any direction, the carrying chassis of the steering capability when seeking to move, typically extremely Few pair of wheels uses universal type wheel.

In addition, in order to ensure stability, the wheel of carrying chassis is in appearance and size can obtain stability most Big width and axletree distance is set.

In the carrying chassis having a structure in which, in keeping or multiple carryings are linked with chassis and carry big During the goods of type etc., such as shown in Fig. 2 (c), in the case where carrying is arranged with chassis in gapless mode, exist What is produced interference between the universal type wheel of adjacent carrying chassis during the rotation of universal type wheel and unfavorable condition occur can Can property.

Utility model content

The utility model problem to be solved

Therefore, in view of the foregoing, stability when ensuring vehicle-mounted its object is to provide and when preventing from being adjacent to The carrying chassis of interference between universal type wheel.

Scheme for solving problem

In order to solve above-mentioned problem, possess in carrying chassis of the present utility model：With horizontal attitude configure it is big Cause the chassis of rectangle and the wheel of set in the bottom surface on the chassis at least two pairs totally four wheels, at least two in the wheel In to totally four wheels being the end wheel that two side ends near leading section and near rearward end are set, the end wheel Totally two wheels around vertical axle rotation to the universal type wheel of arbitrary direction movement from that can constitute at least one pair of, and this is universal Two paired wheels of formula wheel are configured in the way of offseting in the longitudinal direction each other.

In addition, being provided with sliding equipment between the universal type wheel and the chassis, the sliding equipment makes described ten thousand To formula wheel two paired wheels symmetrical position two wheels paired with this are offset each other and left and right is asymmetrical Slided in the longitudinal direction relative to the chassis between position.

Utility model effect

So, universal type wheel is configured to offset in the longitudinal direction, so even by carrying chassis in side In the case of being adjacent to and link upwards, it can also prevent what adjacent universal type wheel from interfering when rotating each other Situation.

Now, the offset dimensions of universal type wheel are the chis calculated to design according to the size of universal type wheel It is very little, but because the axle base of same two pairs of end wheels is compared to smaller, therefore problem will not be produced in terms of stability.

Embodiment

Hereinafter, carrying of the figure shown in (a), (b) and (c) of reference picture 1 to an embodiment of the present utility model Illustrated with chassis 1.

Carrying includes the substantially rectangular chassis 2 configured with horizontal attitude with the basic framework of the bottom of chassis 1 and two pairs common Four wheel wheel 3,3 ', 4,4, each wheel 3,3 ', 4,4 with chassis 2 with according to horizontal attitude be positioned in its each wheel plate 5, 5th, the mode on 5,5 is fixed.

In addition, what the corner that carrying is included in the upper surface of chassis 2 with the basic framework on the top of chassis 1 was fixed with perpendicular attitude Four pillars 6 and multiple mounting platens 7 that are fixed or being detachably arranged between four pillars 6.

What two pairs of two side ends that totally four wheels 3,3 ', 4,4 taken turns are included near the leading section of the bottom surface on chassis 2 were installed The universal type wheel 3,3 ' and two side ends near the rearward end of the bottom surface of chassis 2 of a pair of totally two wheels install a pair totally two The fixed wheel 4,4 of individual wheel.

Now, the universal type wheel 3,3 ' of a pair of totally two wheels is with the universal type wheel 3,3 ' and fixed wheel 4,4 Axle base is respectively that axle base A, B (A ＞ B) mode offset offset dimensions C (C=A-B) and left and right in the longitudinal direction Asymmetricly configure, so as to prevent universal type wheel 3,3 ' adjacent during the link shown in (c) in Fig. 1 from being sent out each other when rotating Raw interference.

Here, the offset dimensions C of universal type wheel 3,3 ' is not interfered in the rotation of universal type wheel 3,3 ' In the range of, the size calculated to design according to the size of each key element of carrying chassis.

Now, the distance between axles of the offset dimensions C of universal type wheel 3,3 ' and universal type wheel 3,3 ' and fixed wheel 4,4 From A, B compared to smaller, thus even in do not link carrying chassis 1 and in the case of separate unit use, in terms of stability also not Problem can be produced.

Alternatively, it is also possible to be folded with sliding equipment between the wheel plate 5 of universal type wheel 3 ' and chassis 2 so that universal The phase between the asymmetrical position offset with the symmetrical position of universal type wheel 3 and with universal type wheel 3 of formula wheel 3 ' Slided in the longitudinal direction for chassis 2, and be provided with the locking mechanism locked in position.

It should be noted that when multiple carrying chassis 1 are linked, passing through (not shown) known or usual link machine Structure links.

In addition, in the present embodiment, being set to the wheel of carrying chassis 1 includes the universal type wheel of a pair of totally two wheels 3rd, 3 ' and a pair of totally two wheels fixed wheel 4,4, but the number on wheel and combination, including at least one pair of totally two Totally four wheels of the universal type wheel 3,3 ' of wheel and generally at least two pairs, can according to the size of carrying chassis 1 and Purposes and suitably set.

Also, carry includes four pillars 6 and multiple mounting platens in the present embodiment with the basic framework on the top of chassis 1 7, but this is not limited to, it can be properly configured certainly according to the size and purposes of carrying chassis 1.
