Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical cranes, and particularly relates to a walking stability device for a metallurgical crane trolley. Background Art

[0002] Metallurgical cranes are special cranes applicable to metal smelting, rolling, hot processing, etc. They include open-hearth charging bridge cranes, ground charging cranes, skip cranes, stripping cranes, mold aligning cranes, cover lifting cranes, tong cranes, slab tilting cranes, forging cranes, heating furnace charging and discharging cranes, skip-electromagnetic cranes, and skip-grab cranes.

[0003] However, for any of the above-mentioned cranes, as the use time of the hoisting trolley prolongs, various factors cause the trolley track to gradually become an "S" shape or an "eight" shape, and phenomena such as extrusion (i.e., rail gnawing) and derailment of the wheels and the track will occur, doubling the operation risk of the overhead crane. Content of the Utility Model

[0004] The purpose of the utility model is to disclose a walking stability device for a metallurgical crane trolley to solve the problems existing in the above background art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A walking stability device for a metallurgical crane trolley includes a base, a connecting plate and guiding and limiting wheels. The base is in an "L" shape. The connecting plate is vertically and fixedly arranged in the middle of the base and extends outwards. The outer extension side of the connecting plate is assembled and connected with the wheels of the hoisting trolley arranged on the track. The guiding and limiting wheels are symmetrically arranged on the left and right sides of the base, and the two guiding and limiting wheels are slidably placed on both sides of the track.

[0007] Furthermore, the guiding and limiting wheels are detachably assembled on the base through a fixed shaft.

[0008] Furthermore, the track is in an inverted "T" shape.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The device of the utility model effectively guarantees the stability of the hoisting trolley when running on the track through the cooperation between the guiding and limiting wheels and the original wheels of the hoisting trolley, avoids the occurrence of rail gnawing and derailment phenomena, and improves the service life and safety redundancy of the metallurgical crane. Description of the Drawings

[0012] Figure 2 This is the side structural view of the present utility model.

[0013] Figure 3 This is the top structural view of the present utility model.

[0014] In the figure, 1 - base, 2 - connecting plate, 3 - guiding and limiting wheel, 4 - track, 5 - wheel. Specific embodiments

[0015] The following further explains and illustrates the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0016] It should be noted that the metallurgical crane described in the present utility model is a double - girder bridge crane. A reverse "T" - shaped track 4 is fixedly installed on the top of the double girders. A hoisting trolley runs on the track 4. The wheels 5 of the hoisting trolley are roller pairs with a "V" - shaped engaging mouth that matches the track 4. However, it is found in long - term use that the track of the hoisting trolley will gradually become "S" - shaped or "eight" - shaped due to various factors (such as heavy load, frictional heat, etc.), causing phenomena such as extrusion (i.e., rail gnawing) and derailment of the wheels from the track between the wheels and the track, resulting in a sharp increase in the operating risk of the crane. And this risk cannot be avoided. When the crane is normally overhauled, maintenance personnel cannot accurately judge where the upper track is distorted, so it cannot be processed, greatly interfering with the normal service life of the crane and shortening the service life of the crane.

[0017] Therefore, based on on - site maintenance experience, the present utility model creatively designs a simple walking stability device for the hoisting trolley of the metallurgical crane to solve the above - mentioned technical problems.

[0018] As Figures 1-3 shown, a walking stability device for the hoisting trolley of a metallurgical crane includes a base 1, a connecting plate 2 and two guiding and limiting wheels 3. The base 1 is in an "L" - shaped structure. The connecting plate 2 is vertically and fixedly arranged in the middle of the base 1 and extends outward, and the outer extension side of the connecting plate 2 is assembled and connected with the wheels 5 of the hoisting trolley arranged on the track 4. The two guiding and limiting wheels 3 are symmetrically assembled on the left and right sides of the base 1, and a receiving space for the track 4 is formed between the two guiding and limiting wheels 3. During use, the wheel surfaces of the two guiding and limiting wheels 3 are in contact with the side surface of the track 4.

[0019] Working principle: The base 1 is connected to the wheels 5 of the original hoisting trolley through the connecting plate 2. When the wheels 5 roll forward along the top of the track 4, the two guiding and limiting wheels 3 installed on the base 1 also roll in contact with the side surface of the track 4, restricting the abnormal rail gnawing of the wheels 5, thereby improving the running stability of the hoisting trolley.
