Description

A height-adjustable movable tire frame

technical field

The utility model relates to the field of steel structure processing, in particular to a height-adjustable movable tire frame.

Background technique

How to reduce or even prevent the deformation of thin-walled steel structure members during the production process has always been a difficult point. In particular, the factors such as relatively thin plate thickness, relatively large area and relatively small overall stiffness of the components have greatly increased the difficulty of production and transportation. In addition, some components require hot-dip galvanizing. The high temperature in the hot-dip galvanizing process releases the welding stress inside the thin-walled components, resulting in partial or even overall deformation. The current anti-deformation technology mainly starts from the way of hoisting: adding an appropriate number and size of lifting lugs to the main load-bearing positions of thin-walled components, and hoisting them in series with steel wire ropes. When adjusting and transporting, the balance beam is used to draw out multiple hooks, which are evenly distributed at the appropriate positions of the components for lifting and transporting. However, this method needs to set up balance beams with different specifications and re-plan the positions of the lifting points according to the different forms of components and the position of the center of gravity; in this way, the efficiency of hoisting and transportation of the steel structure is greatly delayed.

SUMMARY OF THE INVENTION

The purpose of the present utility model is to overcome the above-mentioned defects, and to provide a tire frame for steel structure work which is easy to implement and can greatly improve the hoisting and transportation efficiency of the steel structure and play a protective role.

In order to achieve the above-mentioned purpose, the utility model is realized in this way:

A height-adjustable movable tire frame includes an assembled support platform, height-adjustable outriggers arranged at the four corners of the bottom of the support platform, and universal rollers arranged at the bottom of the outriggers; wherein the assembled support The platform refers to an external frame enclosed by four sections of angle steel and a plurality of beams arranged in sequence and running through both sides of the external frame. Both ends of the beam are fastened with nuts, and the height-adjustable legs are welded to the supporting platform. The four corners of the bottom, the height-adjustable legs include a round tube, a nut welded at the bottom opening of the round tube, and a screw threaded with the nut, and the bottom of the screw is provided with a universal roller; The outriggers enable the movable tire frame to adapt to the transportation work in different spaces, and at the same time, after the screws are removed, the supporting platform can also carry steel structures and be used for hoisting operations.

The height-adjustable movable tire frame is provided with a sleeve at the bottom of the screw rod, and the top end of the universal roller and the bottom end of the screw rod are all set in the sleeve; a spring is also arranged in the sleeve, and the spring It is located between the top end of the universal roller and the bottom end of the screw, so as to play the role of shock absorption and buffering.

The device raises the height of the whole tray by adjusting the nut and screw of the column foot of the tray. The connection between the pulley sleeve and the screw at the bottom of the column foot is 360° rotatable, so that the pulley of the tray can be rotated at any time. The device greatly reduces the number of hoisting and transportation of thin-walled easily deformable components in the production process, and plays the role of preventing the components from being deformed during the hoisting and transportation process. In addition, the tire frame can be reused, and its good mobility also effectively reduces the workload of the workshop.

Further, the supporting distance of the supporting platform of the tire frame can be flexibly adjusted: the supporting platform is composed of angle steel, beams and nuts. The vertical and horizontal beams are fixed on the angle steel by the nuts on both sides of the inner and outer sides, and the span between the screws can be adjusted according to the size and type of the components, so as to ensure that the parts to be installed on the reverse side of the thin-walled components do not collide with the supporting screws during production (if the components If the parts that need to be riveted and welded collide with the support screw of the panel, the collision screw can be removed or the position of the screw support can be adjusted through the oblong hole to adjust the distance, so as to ensure the support and avoid collision). Guaranteed assembly and welding of parts without turning over.

The height of the tire frame can be adjusted: the adjustable height of this tire frame brings great convenience to the processing of thin-walled components; when the area of the component is large, the rigidity is small, and the plate thickness is thin, first adjust the tire frame to Assemble and weld the upper surface of the main component at a height suitable for workshop workers to operate. After the assembly and welding of one side is completed, the tire frame is raised to a certain height, and the components do not need to be turned over. The riveter positions the parts that need secondary assembly on the other side for riveting and positioning, and selects a welder who is skilled in overhead welding for overhead welding. Welding (because the plate of the thin-walled component is relatively thin, the welding is basically in the form of fillet weld, and the overhead welding basically does not reduce the welding quality). The height adjustment avoids deformation caused by turning over the components in the unformed state.

The tire frame can also be moved; the lower part of the tire frame is composed of several supporting feet, and the lower part of each supporting foot is provided with a movable pulley. The side of the pulley is accompanied by a latch that can lock the pulley at any time and fix the tire. Stand still. When the thin-walled components are fabricated and welded, the tire frame can be pushed directly and poured out of the workshop. It reduces the multiple lifting process and plays a good role in protecting the deformation of the components.
