Description

A kind of roll change buggy

(1) technical field

The utility model relates to color coating accessory equipment field, particularly a kind of roll change buggy.

(2) background technology

Color coated steel sheet is clad steel sheet (zinc-plated, aluminum-zinc alloy, cold drawing etc.) to be carried out to the chemical conversion treatment such as degreasing, phosphatization, chromic salts acid passivation, is then coated with organic coating, then the product of making through baking.The mechanical strength of its existing steel plate and easy-formation performance, have again good ornamental and corrosion stability, is widely used in building, household electrical appliances, furniture, the every field such as common facilities and communications and transportation.At present, existing colour-coating technology adopts method of roll coating conventionally, and this technique colored steel coating adhesion is strong, can keep for a long time color and luster vivid.But because of factors such as paint roller operating cycles, application colour changing and product specification variations, need to regularly replace paint roller, and change paint roller, conventionally adopt the push-and-pull that cooperatively interacts of traditional artificial and hoisting crane to realize, because paint roller is heavier, volume is larger, said method is consuming time longer, labour intensity is bigger than normal, and there is potential safety hazard, in paint roller transportation, easily cause paint roller to damage, particularly workshop high across with platform under, in roll change process, workshop crane can not be used due to equipment obstacle, and roll change work difficulty further strengthens.

(3) summary of the invention

The utility model is in order to make up the deficiencies in the prior art, a kind of rational in infrastructure, convenient and practical, roll change buggy of being convenient to control, greatly reduce roll change difficulty is provided, this roll change buggy can be realized roll coater roll change fast, safely and steadly, has solved problems of the prior art.

The utility model is achieved by the following technical solution:

A roll change buggy, comprises a base, is provided with four cardan wheels in the bottom of base, at the top of base, is symmetrically arranged with two root posts, and the middle part by rotating shaft and a crossbeam between two root post tops is hinged, and at the two ends of crossbeam, is respectively provided with a holding device; On crossbeam, offer a pin-and-hole, offer the mounting hole with the corresponding cooperation of pin-and-hole on column, an alignment pin is inserted in pin-and-hole and mounting hole; On the base with the opposing side of mounting hole, be provided with an inverse-U-shape rack relative with crossbeam position, in one end of crossbeam, be provided with leader.

Described holding device comprises train wheel bridge and the lower plate being bolted to connection, lower plate and crossbeam are connected, and after the train wheel bridge semicircle breach relative with all offering a position on lower plate and train wheel bridge and lower plate docking, two semicircular v notch v forms a circular clamp port.

The beneficial effects of the utility model are: this roll change buggy, and rational in infrastructure, convenient and practical, can reduce roll changing time, reduce roll change labour intensity, improve the safety of roll change; The cardan wheel arranging in base bottom, can make this roll change buggy turn to more flexible, is easy to control; The mode that adopts column and crossbeam to be hinged, holding handle can erect paint roller easily, in roll change process, occupies little space, and is particularly suitable for high across using with the little place of platform space in workshop, without a dead lift, when reducing labour intensity, reduced roll change risk; Holding device makes paint roller unsettled in transportation, avoids contacting with crossbeam, effectively prevents paint roller surface damage, has also eliminated the potential safety hazard that paint roller is rolled and dropped simultaneously, in transportation paint roller process, also can not cause paint roller to damage; Between crossbeam and column, adopt pin-and-hole to be connected with alignment pin inserting mode, in the time of so just can effectively preventing paint roller lifting, crossbeam rocks, and causes paint roller and crossbeam collision impaired; Inverse-U-shape rack can be played a supporting role to crossbeam, more laborsaving, safer, more stable in transportation paint roller process, is suitable for wide popularization and application.

(4) accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the part right elevation of Fig. 1;

Fig. 3 is the structural representation of holding device in Fig. 1.

In figure, 1 base, 2 cardan wheels, 3 columns, 4 rotating shafts, 5 crossbeams, 6 alignment pin, 7 inverse-U-shape racks, 8 handles, 9 bolts, 10 train wheel bridges, 11 lower plates, 12 circular clamp ports.

(5) specific embodiment

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in Fig. 1-Fig. 3, this embodiment comprises a base 1, is provided with four cardan wheels 2 in the bottom of base 1, is symmetrically arranged with two root posts 3 at the top of base 1, middle part by rotating shaft 4 and a crossbeam 5 between two root post 3 tops is hinged, and at the two ends of crossbeam 5, is respectively provided with a holding device; On crossbeam 5, offer a pin-and-hole, offer the mounting hole with the corresponding cooperation of pin-and-hole on column 3, an alignment pin 6 is inserted in pin-and-hole and mounting hole; On the base 1 with the opposing side of mounting hole, be provided with an inverse-U-shape rack 7 relative with crossbeam 5 positions, in one end of crossbeam 5, be provided with leader 8; Described holding device comprises train wheel bridge 10 and the lower plate 11 being fixedly connected with by bolt 9, lower plate 11 is connected with crossbeam 5, and after the train wheel bridge 10 semicircle breach relative with all offering a position on lower plate 11 and train wheel bridge 10 and lower plate 11 docking, two semicircular v notch v forms a circular clamp port 12.
