Abstract

The present invention relates to a lifter for vehicle maintenance, which is to provide a lifter for vehicle maintenance with light-weighted pillars and driving device to simplify the installation work and with lower cost. The solution of the present invention is to configure with a sliding frame 11 of the installation member 14 for supporting the support arm of the vehicle, which is sliding on the inner side of the pillar 10 with the guide slide 12. Because the guide slide 12 can be rotatable around the installation shaft 13, even though the inner side of the pillar 10 is bent, it can be continuously contacted. Thus, the guide slide 12 supported on the installation shaft 13 by the shaft can be rotatable along the bending and evenly contacted even though the sliding surface formed by the inner surface of the pillar 10 is also bent. Therefore, it will not generate the biased wearing on the guide slide 12 by the increasing of contact pressure caused by biased wearing in the conventional technique to make the replacement period earlier, or increasing the anti-sliding property to generate extra loading on the driving power of the lifter, or for the sliding surface of the inner side of the pillar, it is not necessary to increase the contact surface pressure and thus the pillar strength due to the smaller contact area.

Lift for repairing vehicle

Technical field

The present invention relates to a kind of one-mast support formula or have two improvement with many column support types lift for repairing vehicle of upper supporting column, more particularly, the present invention has a kind ofly carried out improved lift for repairing vehicle to the carrying balladeur train that moves, be provided with members such as support arm along above-mentioned pillar on its attachment face and the contact part of pillar.

Background technology

In the two pillar lift for repairing vehicle of the lift for repairing vehicle before a kind of, the support arm of supporting vehicle is installed on the carrying balladeur train, this carrying balladeur train can remain on vehicle on the suitable height thus along the pillar of upright setting towards upper and lower to moving.On the attachment face that is provided with member such as support arm of carrying balladeur train or with the perpendicular side of this attachment face on roller or guide block are installed, by making roller, the carrying balladeur train is moved up and down along pillar propping up cylinder commentaries on classics last time or guide block being slided on a cylinder.

Because roller is that line contacts with a cylinder, footprint pressure is bigger, thereby must will prop up cylinder and make heavy wall, must adopt crash-resistant member accordingly with frictional loss.And because guide block is bigger with the area of contact of a cylinder, compare, can make footprint pressure to reduce significantly with roller, thereby just need not guarantee the local strength of the pillar sliding surface that guide block slides, as long as be held in the bulk strength of pillar appropriate just passable, can make the weight saving of elevator single-piece, and can make and construction being set simplifying.

Fig. 6 is the exploded drawings that the carrying balladeur train 11 of guide block 12 is installed.Carrying balladeur train 11 is provided with the installation component 14 of support arm in the lower end of attachment face 11a, fastening respectively mount pad 13a, the 13a of cuboid on the side vertical with this attachment face 11a.On each mount pad 13a, respectively its mulched ground is installed with

guide block

12,12, these guide blocks are face openings making cuboid, inside is empty.

Fig. 7 is illustrated under the state that makes guide block and pillar that the carrying balladeur train is installed contiguously, near the cross-sectional view of guide block the pillar cut-out being obtained.Upright being located at is arranged on the ground base plate, becomes roughly the pillar 10 of " コ " word shape will carry balladeur train 11 to the direction of traffic opening to wrap in its inboard, can make carrying balladeur train 11 mobile up and down by drive

member.Guide block

12,12 intercalations that are provided with highlightedly on the two sides of carrying balladeur train 11 in the slip ditch 10b of pillar 10, three surfaces of guide block 12 with pillar 10 in contact towards upper and lower to mobile.

Summary of the invention

But, because the installation error when being installed to guide block on the outstanding mount pad that is arranged on the pillar, the shaping error of guide block body, the scale error of pillar, guide block can not contact with the sliding surface of pillar like that by the designing institute requirement, only contact with the part of sliding surface, make thus with respect to the area of contact of pillar and dwindle, footprint pressure is increased, thereby will essentially strengthen column strength, the elevator that can produce weight increases is wasted time and energy when construction is set, the price of elevator itself raises, on guide block, produce uneven abrasion and shorten the replacement time, sliding resistance increases and increases the situation of the driving power burden of elevator.

The present invention makes for the problem that solves above-mentioned prior art existence, and its objective is provides a kind of lift for repairing vehicle, and it has brought into play the advantage as the guide block of carrying balladeur train reciprocating mechanism largely; Compare with the former the sort of elevator that is provided with the carrying balladeur train of roller, can make weight saving, make be provided with easy construction easily and also price more cheap.

Technical scheme 1 described invention is that a kind of one or both sides at base erectly are being provided with pillar, have along this upright pillar that is provided with towards upper and lower to the carrying balladeur train that moves, on the side vertical of this carrying balladeur train, erectly be provided with assembled shaft at the lift for repairing vehicle that the vehicle maintaining body is being set on the attachment face of this carrying balladeur train with above-mentioned attachment face, on this assembled shaft, guide block can be installed freely to rotate, the bending of this guide block and pillar contact surface is rotated with matching, slides equably simultaneously.Thus, even there is bending on the pillar contact surface, the guide block that axle is bearing on the assembled shaft also can rotate, be in contact with it equably all the time simultaneously along this bending, can not increase because of uneven abrasion makes contact pressure as before; Owing to uneven abrasion takes place on the guide block accelerated the replacing time; Increase the weight of the burden of propulsive effort owing to resistance to sliding increases, and can not diminish and contact surface is pressed and increased, thereby needn't increase the intensity of pillar, can not make construction being set being difficult to carry out, price is increased owing to the contact surface relative with the sliding surface of pillar.

Wherein, base can be arranged on the ground of keeping in repair regularly or bury in ground, and the structure that perhaps make and install wheel, it can be moved to the operation place like this, can be omitted pillar is set directly on the ground.The side of so-called base be meant with keep in repair with the turnover direction of vehicle relative laterally, be not self to advance but make with other members under the occasion that maintenance moves with vehicle, the front and back position of vehicle also becomes the side.

About pillar that the vehicle maintaining body is being set towards the side, in two pillar lift for repairing vehicle, be the mutual subtend of peristome that makes each pillar, betwixt with vehicle configuration.Also have 2 pillars are configured in vehicle front-wheel adjacency respectively, with peristome be arranged on each rectangular pillar of transversal surface, with perpendicular 2 faces of the face of vehicle subtend in the rear wheel-side cylinder on or on the cylinder of vehicle approaching side.
