Abstract

The utility model discloses a correction auxiliary device for motion bias rail of a crane car, which comprises a steel rail, end beams horizontally arranged above the steel rail, wheels respectively arranged on the lower side of two ends of the end beams and supported on the steel rail and bolt roller bearings symmetrically arranged at the lower ends of connection frames on two sides of the end faces. Each connection frame comprises a vertical plate, a transverse plate fixedly and vertically connected with the lower side of the vertical plate and a plurality of hook plates meshed with bearings on the upper side of the steel rail in shape, and the connection frames are arranged outside the wheels and respectively fixed on two sides of the end beams. The bolt roller bearings are arranged on two sides of the bearings on the upper portion of the steel rail, and the hook plates are respectively fixed on the lower side of the connection frames. The correction auxiliary device for motion bias rail of the crane car avoids bias rail, rail gnawing and rail climbing of wheels. Simultaneously, the hook plates on the lower side of the connection plates, safety hazards are removed, and safety performance of the crane is improved.

Description

Crane moves inclined to one side rail and proofreaies and correct auxiliary device

Technical field

The utility model relates to a kind of hoisting crane, and especially a kind of crane moves inclined to one side rail and proofreaies and correct auxiliary device, belongs to the weight-lifting equipment technical field.

Background technology

Existing mono beam crane in bridge type cart operation wheel all adopts two-wheel edge structure, and wheel is installed in end carriage two ends downside, and is supported on the rail; Because in the making of wheel, installation process; There are error in the planeness and the squareness of each wheel tread, add that also there is installation error in the crane orbit, are easy to generate side force when causing hoisting crane work; Make hoisting crane produce inclined to one side rail, gnaw rail and climb phenomenons such as rail, exist bigger potential safety hazard.

Summary of the invention

The purpose of the utility model provide a kind of simple in structure, can prevent effectively that crane that hoisting crane produces phenomenon such as inclined to one side rail from moving inclined to one side rail and proofreading and correct auxiliary device.

The utility model is achieved through following technical scheme:

A kind of crane moves inclined to one side rail and proofreaies and correct auxiliary device; Comprise rail, be set in parallel in the end carriage of rail top; Be separately positioned on end carriage two ends downside and be supported on the wheel on the rail, be symmetricly set on the link span of end carriage both sides, be arranged on the bolt roller bearing of link span lower end; Link span comprise riser, with riser downside vertical fixing bonded assembly transverse slat, several piece shape and the identical hook plate of rail upside support strip, link span is positioned at lateral wheel, is separately fixed on the end carriage both sides; Said bolt roller bearing is positioned at the support strip both sides on rail top; Said hook plate is separately fixed at the link span downside.

The purpose of the utility model can also further realize through following technical measures.

Aforesaid crane moves inclined to one side rail and proofreaies and correct auxiliary device, and distance A is less than said wheel tread width B between the bolt roller bearing outer peripheral face of wherein said rail both sides.

Aforesaid crane moves inclined to one side rail and proofreaies and correct auxiliary device, and wherein said riser is fixed on the end carriage two ends through several fasteners, and the riser outside is respectively equipped with several trimming screws, and trimming screw one end passes riser and is resisted against on the end carriage lateral surface.

The utility model is set up link span in the end carriage both sides of lateral wheel; The link span lower end is provided with bolt roller bearing, and when hoisting crane work produced side force, the bolt roller bearing outer peripheral face of the side that squints was resisted against on the rail side; Avoid the inclined to one side rail of wheel rim, gnawed rail and climbed the generation of phenomenons such as rail; The hook plate of link span downside can prevent wheel derailment simultaneously, has eliminated potential safety hazard, has improved the safety performance of hoisting crane.The utility model is simple in structure, and cost is low, and is convenient for installation and maintenance.

Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.

Description of drawings

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

Fig. 2 is the left view of Fig. 1.

The specific embodiment

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

Like Fig. 1, shown in Figure 2, the utility model comprises rail 1, be set in parallel in the end carriage 2 of rail 1 top, be separately positioned on end carriage 2 two ends downsides wheel 3, be symmetricly set on end carriage 2 both sides link span 4, be arranged on the bolt roller bearing 5 of link span 4 lower ends.Wheel 3 is supported on the rail 1; Link span 4 is positioned at wheel 3 outsides; Comprise riser 41, with transverse slat 42, the two block-shaped hook plates 43 that coincide with rail 1 upside support strip 11 that riser 41 downside vertical weldings connect, riser 41 is fixed on end carriage 2 both sides through 6 bolts 6 respectively, riser 41 outsides are respectively equipped with 4 trimming screws 7; Trimming screw 7 one ends pass riser 41 and are resisted against on end carriage 2 lateral surfaces, are used for spacing between adjustable bolt roller bearing 5 and the rail 1 upper support bar 11; Bolt roller bearing 5 is positioned at support strip 11 both sides on rail 1 top, and its bolt is captiveed joint with transverse slat 42, and the distance A between bolt roller bearing 5 outer peripheral faces of rail 1 both sides can avoid wheel 3 wheel rims to gnaw rail 1 less than wheel 3 tread width B.Hook plate 43 is weldingly fixed on both sides, transverse slat 42 below respectively, in case when serious skew takes place for end carriage 2, can avoid wheel 3 derailings.

Except that the foregoing description, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
