Abstract

The utility model discloses a device for adjusting limit of a cart rail of a crane and an installing method, belonging to the field of large machine parts. The utility model aims to eliminate a rail pressing plate and adopts a steel rail limiting adjusting device. According to the device, a large bolt penetrates through rail beams and a sleeper, the bottom end of the large bolt is clamped by using a nut, the upper end of the large bolt is clamped on a pad by a large nut, an adjusting bolt penetrates through multiple pads, the front end of the adjusting bolt is pressed on the rail pressing plate, the rail pressing plate is arranged on the upper surface of the lower edge of the rail, rail limiting plates are arranged at two sides of the lower edge of the rail, and are fixed on a bottom plate through small bolts, and the bottom plate is arranged on the rail beams at two sides of the sleeper. The device overcomes the defects of the prior art, is simple in structure and accurate and reliable in rail location, and brings convenience for adjusting the rail. Before the device for adjusting the limit of the cart of the rail of the crane is used, more than four rails of the cart are broken every year; and after the device for adjusting the limit of the cart of the rail of the crane is used, no rail of the cart is broken.

Description

A kind of device of adjusting crane railway limit

Technical field

The utility model belongs to big machinery accessory field.

Background technology

Hoisting crane is the main handling appliance of originating firm, no matter from the person or device security, consider, once have an accident, what impact was produced carries out smoothly, crane track beam is concrete, the damping of large Car Track is wooden, during hoisting crane long-play, very easily produces the phenomenon that rail pressing plate de-orbits, cause cart rotation browsing rail, big wheel wheel wear, causes hoisting crane vibrations, steel structure damage, track fracture, the service life of reducing hoisting crane.

Summary of the invention

The purpose of this utility model is to cancel rail pressing plate, changes a kind of device of adjusting crane railway limit of the spacing setting device of rail into.

King bolt of the present utility model is through track girder and sleeper, and block by nut bottom, and it is upper that upper end is stuck in pad by big nut, adjusts bolt and wears many pads, and front end is pressed on rail pressing plate, and rail pressing plate is placed in the lower to upper surface of track; At the lower railway limit plate that is provided with along both sides of track, railway limit plate is fixed on base plate by stove bolt, and base plate is arranged on the track girder of sleeper both sides.

The utility model has overcome prior art shortcoming, simple in structure; Tracks positioned accurately and reliably.Orbit adjusting is convenient.Before using the device of this kind of adjustment crane railway limit, large Car Track all ruptures more than 4 every year, large Car Track fracture does not occur after using this kind of setting device.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is that the utility model Figure 1A-A is to view;

Fig. 3 is that the utility model Figure 1B-B is to view.

The specific embodiment

King bolt 10 of the present utility model is through track girder 1 and sleeper 2, and block by nut bottom, and upper end is stuck on pad 3 by big nut, adjusts bolt 4 and wears many pads 3, and front end is pressed on rail pressing plate 8, and rail pressing plate 8 is placed in the lower to upper surface of track 6; At the lower railway limit plate 7 that is provided with along both sides of track 6, railway limit plate 7 is fixed on base plate 9 by stove bolt 5, and base plate 9 is arranged on the track girder 1 of sleeper 2 both sides.

Installation method of the present utility model is:

A, cut two base plates, a hole is bored respectively in both sides, is placed on the both sides of sleeper under track and paves with track bottom surface to be adjacent to;

B, cut four blocks of railway limit plates, bore respectively a hole and be placed on and on the base plate of track both sides, be close to track side surfaces and connect with primary screw;

C, cut two rail pressing plates, be pressed in respectively under the track of track both sides along upper surface, respectively with two blocks of railway limit plates link together, and with electric welding and track, form one;

D, by four, adjust bolts, two two 1 groups are clipped in respectively on the follower bolt of track girder both sides and are welded on the rail pressing plate of track both sides, according to the distance of two bolts, making two pads is enclosed within respectively on bolt, with nut, adjust the gauge of track, after having adjusted by base plate and railway limit plate weld together.

The example that an applicant once specifically applied is below described: the original intention of invention is how to limit the in use change of straightness accuracy of crane track, and orbit adjusting is quick and easy.

The spacing setting device of rail is made

1), cut the base plate of 2 110 * 350 * 16, the hole of 1 14 is bored respectively in both sides, 210 millimeters of pitch-rows, the screw thread of attacking M16, is placed on the both sides of sleeper under track and paves with track bottom surface and be adjacent to.

2), cut the railway limit plate of 4 90 * 100 * 16, bore respectively the hole of 1 20 and be placed on the screw that is close to M16 for track side surfaces * 40 on the base plate of track both sides and connect.

3), cut the rail pressing plate of 2 40 * 330 * 12, be pressed in respectively the track bottom surface of track both sides, the railway limit plate of respectively with 2 90 * 100 * 16 links together, and with electric welding and track, forms one.

4), by 4 M16 * 180 bolts, two two 1 groups are clipped in respectively on the follower bolt of track girder both sides and are welded on the rail pressing plate of track both sides, according to the distance of two bolts, making 2 pads is enclosed within respectively on bolt, with nut, adjust the gauge of track, after having adjusted by base plate and railway limit plate weld together.

Improved railway limit setting device for the first time

With one, the bolt of M18, make 25 annulus, be enclosed within on rail pressing plate bolt, the hole of a first track stud brill 20 is passed, and cancels pressing plate, with nut, adjusts restriction track.
