Anti-tipping device of crane trolley

Technical Field

The utility model belongs to the technical field of the heavy industry hoisting equipment and specifically relates to a monkey anti-tilt device.

Background

The crane refers to a multi-action crane for vertically lifting and horizontally carrying heavy objects within a certain range. Also known as crown blocks, navigation cranes and cranes.

The crane end beam is a key component for bearing hoisting operation, walking wheels of a crane trolley arranged on the end beam can generate abrasion in the long-term use process, at the moment, if the travelling speed of the crane trolley is too high, the walking wheels on the crane end beam can directly fall off from a track, and as a heavy object is hoisted on a crane, the crane trolley is very dangerous to tumble.

SUMMERY OF THE UTILITY MODEL

To exist among the prior art that current trolley takes place the in-process that tumbles to press from both sides rail equipment and can contact with I-steel track surface and cause wearing and tearing, long-time wearing and tearing tend to reduce I-steel track life's problem, the utility model provides a trolley anti-tilt device can avoid the emergence of above-mentioned problem.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a monkey anti-tilt device, includes the installation shell, be provided with mounting panel, rubber pad and bolt on the installation shell, the symmetry is provided with two fixed blocks on the mounting panel, fixed block female connection has the long screw, the one end of long screw passes fixed block threaded connection and has anti-tilt platform, be provided with the steel ball in the anti-tilt platform.

The device can effectively prevent the walking wheels from being separated from the rail due to abrasion in long-time use, improves the safety in the hoisting process, prevents the rail clamping equipment from causing abrasion to the I-shaped steel rail in the anti-tipping process, and prolongs the service life of the I-shaped steel rail.

Furthermore, a plurality of installation positions are arranged on the installation shell, installation screws are arranged on the installation positions, and anti-tipping platforms are connected to the installation screws in a threaded mode.

When the device is used for a period of time, the new anti-tipping platform and the new steel ball are replaced in time, and the anti-derailing effect is ensured.

Furthermore, a special buffer for a crane is further arranged on the mounting shell.

The special buffer for the crane prevents the device from colliding with other parts at the initial end and the tail end of the crane to cause damage.

Furthermore, two rubber pads and two rows of bolts are symmetrically arranged on the mounting shell.

And the rubber pads and the bolts are used for ensuring the firm connection between the mounting shell and the end beam of the crane.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the device can effectively prevent the travelling wheels from being separated from the track due to abrasion in long-time use, the steel balls are driven to contact with the track by rotating the long screw rod, the overturning is effectively prevented, the track is not damaged, the safety in the hoisting process is greatly ensured, the rail clamping equipment cannot abrade the I-shaped steel track in the overturning prevention process, and the service life of the I-shaped steel track is prolonged;

2. the special buffer of hoist has been add to this device and has been protected the device, is provided with the anti-tilt platform that a plurality of installation positions cooperation installation screw rod made things convenient for a period of time to renew at any time simultaneously on the installation shell, guarantees the derailment prevention effect of monkey.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 3, a tipping prevention device for a crane trolley comprises a mounting shell 3 and a crane trolley, wherein the crane trolley comprises an end beam and a travelling wheel 2, the crane trolley is not improved in the prior art, the end beam is not shown in the figures, the mounting shell is connected with the end beam, the mounting shell is mounted on two end faces of the end beam, specifically, two rubber pads 36 and two rows of bolts 37 are symmetrically arranged on the mounting shell, the purpose of designing the rubber pads can be achieved by performing a primary fixing function in the mounting process of the mounting shell and the end beam, the bolts sequentially penetrate through the mounting shell and the rubber pads to be in threaded connection with the end beam, the double fixing enables the connecting effect of the mounting shell and the end beam to be good, the subsequent tipping prevention effect of the crane trolley is ensured, a track 1 is arranged right below the travelling wheel, and the travelling wheel is matched with the track, the travelling wheel is driven by a driving device arranged on a crane trolley to move along a track to carry out a lifting, hoisting and transferring process, a following anti-tipping structure is designed in the running process to improve the lifting safety, the crane trolley cannot tip, the mounting shell is provided with a mounting plate 31, the mounting plate is symmetrically provided with two fixing blocks 32, the fixing blocks are in threaded connection with long screws 33, one ends of the long screws penetrate through the fixing blocks and are in threaded connection with an anti-tipping platform 34, steel balls 35 are arranged in the anti-tipping platform and are matched with the track, the two long screws are manually rotated before the lifting starts to enable the steel balls to be in contact with the track, the track cannot be damaged, the steel balls can be freely rotated in the anti-tipping platform to prevent the travelling wheel from tipping, when the anti-tipping platform needs to be replaced, the long screws are firstly rotated in the opposite direction to enable the steel balls to be far away from the track, the anti-tipping platform is detached and replaced, the anti-tipping effect of the device is good, and the rail cannot be damaged.
