Description

Large-tonnage mining scraper

Technical Field

The utility model relates to an engineering vehicle technical field, in particular to large-tonnage mining scraper.

Background

Along with the national energy strategy transformation adjustment, the coal industry of China is about to enter a platform period after capacity adjustment, the country closes a medium-sized coal mine and a small-sized coal mine, large-sized coal mine development is encouraged, newly-increased mines are inevitably transported by trackless rubber-tyred vehicles, certain increment is brought, meanwhile, certain increment is brought under the driving of internal factors for improving the work efficiency of the industry, and the requirements of the coal mine on various machines, particularly large auxiliary equipment are continuously increased. The scraper is widely applied to the aspects of shoveling, carrying, unloading materials and the like, can greatly reduce the labor intensity of underground workers, improves the production efficiency, reduces the labor cost, and has a wider market.

At present, the underground coal mine scraper is divided into two types, one type is the scraper with the weight of below 15 tons which is generally used, and the other type is a scraper with the weight of above 40 tons which basically takes an import as a main part. When transporting about 20 tons of equipment with 15 tons or more underground, only 40 tons of imported scrapers or 25 tons of domestic scraper type bracket carriers can be used.

The shovel plate type support carrier is used, and the shovel plate can only swing, so that the shovel loading function is not provided, and a large-tonnage hydraulic hoist needs to be used for dragging. The device is easily influenced by various aspects such as ground conditions, dragging positions, personnel operation and the like in the dragging process, and has the defects of low efficiency, poor safety and reliability and the like.

Therefore, the vehicle model is required to be improved to adapt to special working condition environment.

SUMMERY OF THE UTILITY MODEL

A main object of the present invention is to provide a large-tonnage mining scraper, which can be used to carry out scraping operations more conveniently.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a large-tonnage mining scraper, includes front truck frame and the front fork that is located front truck frame the place ahead, even there is the upset hydro-cylinder between the rear portion top of front fork and the rear portion top of front truck frame, even there is the lifting movable arm between the middle of the rear portion of front fork and the middle of the rear portion of front truck frame, even there is the lifting oil jar between the middle part of lifting movable arm and the lower part of front truck frame, the both ends of upset hydro-cylinder, lifting movable arm and lifting oil jar are articulated.

Specifically, the lifting movable arm has a structure with an arched middle part, and the hinged position of the lifting movable arm and the lifting oil cylinder is located at an arched position.

Specifically, the front fork is provided with a detachable shovel plate.

Adopt above-mentioned technical scheme, the utility model discloses technical scheme's beneficial effect is:

the utility model discloses make the front fork can satisfy and insert and lift the requirement, also can accomplish the upset action, possess functions such as shovel dress, transport, uninstallation material, the transportation requirement of equipment about 20 tons can be accomplished more easily to the cooperation large-tonnage hydraulic block.

FIG. 2 is a top view of the large tonnage mining scraper of an embodiment in an initial state;

FIG. 3 is a front view of the embodiment of a large tonnage mining scraper as the front fork is raised;

FIG. 4 is a front view of the large tonnage mining scraper with the front fork turned down according to an embodiment;

FIG. 5 is a front view of the large tonnage mining scraper front fork of the embodiment turning up.

The figures in the drawings represent:

the method comprises the following steps of 1-a front frame, 2-a front fork, 3-a turnover oil cylinder, 4-a lifting movable arm, 5-a lifting oil cylinder, 6-a shovel plate and 7-a large-tonnage hydraulic hoist.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 5, the utility model discloses a large-tonnage mining scraper, including preceding frame 1 and the front fork 2 that is located preceding frame 1 the place ahead, even have upset hydro-cylinder 3 between the rear portion top of front fork 2 and the rear portion top of preceding frame 1, even have between the middle of the rear portion of front fork 2 and the rear portion of preceding frame 1 and lift movable arm 4, even have between the middle part of lifting movable arm 4 and the lower part of preceding frame and lift hydro-cylinder 5, upset hydro-cylinder 3, lift movable arm 4 and lift hydro-cylinder 5's both ends are articulated. Two rotatable points are arranged at the rear part of the front fork 2, when the front fork 2 finishes lifting action, the lifting oil cylinder 5 drives the lifting movable arm 4 to swing upwards, so that the front fork 2 can also rotate by taking a connecting shaft of the lifting movable arm 4 on the front frame 1 as a circle center, and the front fork 2 also approximately performs lifting action because the axis of the lifting oil cylinder 5 is basically in a vertical direction; when the turnover oil cylinder 3 moves, the front fork 2 rotates by taking the connecting shaft of the lifting movable arm 4 on the front fork 2 as a circle center, and the downward shoveling and shoveling actions are expressed at the front end of the front fork 2. Therefore, the front fork 2 can meet the insertion and lifting requirements, can also complete the overturning action, and has the functions of shoveling, carrying, unloading materials and the like. The overturning oil cylinder 3 and the lifting oil cylinder 5 both operate under the power provided by the large-tonnage hydraulic hoist 7, the load is related to the performance of the large-tonnage hydraulic hoist 7, and the scraper can easily meet the transportation requirement of about 20 tons of equipment through the structure.

As shown in fig. 1, 3 to 5, the lifting boom 4 has a structure in which the middle portion is arched upward, and the hinge position of the lifting boom 4 and the lifting cylinder 5 is in the arched position. The lifting movable arm 4 which is arched structurally improves the strength and the bearing capacity of the lifting movable arm 4, and can avoid a front wheel mechanism and leave a position for arranging the lifting oil cylinder 5.

As shown in fig. 1 and 2, the front fork 2 is provided with a detachable blade 6. When the transportation object is the article that has the bracket, front fork 2 can directly put into operation, when the transportation object does not have special bracket, can increase the support area with shovel plate 6, reduces the goods risk of dropping.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
