Abstract

The utility model relates to the technical field of thin coal seam mining and transportation, in particular to a chute structure of a coal plough or a conveyor. Equipment is difficult to maintain because of space limitation of thin coal seams, and the underground equipment is required to have good stability to adapt to changing work surface conditions, shorten halt maintaining time and lower maintaining cost. According to the chute structure, a sliding frame, a chute body and a baffle are welded into a whole, a sliding frame cover is a constituent part of the sliding frame and in an arc shape, and a board is welded on the sliding frame cover. The board is fixed on the sliding frame through a bolt. The surface B of a semi-circle groove below the sliding frame cover is arranged in cooperation with the surface A of the stretched-out semi-circle end of a guide assembly. A cylinder base is welded on the side where the baffle of the chute structure is located, the upper half portion of the cylinder base is provided with a spherical counter groove, and the lower half portion of the cylinder base is in a traditional pushing lug board shape. A cylinder cover is connected with the cylinder base through a bolt to form a semi-closed ball. The chute structure prolongs the service life of a chute, improves structural stability of the chute, and lowers installing and maintaining workload.

Description

The chute structure of coal plough or conveyer

Technical field

The utility model relates to the technical field of Mining Transport under the girdle coal mine, specifically the chute structure of a kind of coal plough or conveyer.

Background technology

At present, China's thin seam mining is in rising trend, and coal plough is the preferred unit of thin seam mining, but it is very harsh to the work plane conditional request, makes it be difficult to be widely used.Colliery mining face under mine condition differs, even good work plane condition, along with the carrying out of exploitation pushing and sliding, top, base plate condition are also in continuous variation.Tradition combine adopt or the general down-hole corollary equipment of adopting in, hydraulic support is with after conveying equipment is connected, the function of utilizing the flexible realization pushing and sliding of hydraulic cylinder to try to stop people from fighting each other can satisfy the exploitation requirement of general coal-cutting machinery.The girdle narrow space, the excavation in tunnel is compact, the work plane condition is particularly remarkable on the impact of equipment, because coal-cutting machinery is up and down fluctuation along with the fluctuating of base plate, this just will cause the disequilibrium of planing, and work plane top, base plate and hydraulic support be damaged, and be distributed in can not digging lithosphere and can causing damage to coal-cutting machinery of above and below, coal seam, the overload parking be can cause when serious, the damage of equipment and the waste in part coal seam caused.Since be subject to the restriction in girdle space, the overhaul of the equipments difficulty, and this just requires underground equipment will have good compliance and reliability, comes the work plane condition of Adaptive change, reduces fault power time, reduces maintenance cost.

Summary of the invention

The purpose of this utility model is to want to provide the chute structure of a kind of coal plough or conveyer, solves because of coal-cutting machinery and loses damage and the part coal residue problem that the planing level causes coal-cutting machinery and equipment with the fluctuating of work plane.

The technical solution of the utility model is: the chute structure of coal plough or conveyer comprises chute cell body, baffle plate, also comprises balladeur train, and balladeur train, chute cell body, baffle plate adopt to be welded to connect and be integrated the composition chute; The balladeur train lid is the ingredient of balladeur train, and the balladeur train lid is arcuate shape, and the above is welded with plate; Plate is bolted on the balladeur train; The B face of balladeur train lid below semicircle nest cooperates installation with the half nose circle A face that the guidance set on the balladeur train stretches out, and is bolted;

The chute baffle side is welded with the cylinder seat, and the cylinder seat first half is provided with spherical heavy nest, and Lower Half is that tradition is passed the otic placode shape; Cylinder cap and cylinder seat are bolted, and form semiclosed spheroid.

The utility model has the advantages that: adopt this chute structure, can be along with the angle of the upper and lower adjustment chute of the variation of work plane, for coal-cutting machinery provides reliable orbit, the coal-cutting machinery that solution causes because floor undulation rises and falls and damage and the residual problem of part coal of equipment.The balladeur train lid more makes things convenient for the inspection and maintenance of equipment, saves time for turning structure, can in time find the abrasion condition of part in maintenance.The balladeur train of chute, baffle plate and chute cell body adopt welded structure, this structure makes between each parts of chute no longer needs Bolt Connection, thereby has improved the application life of chute self and the stability of structure, have reduced the workload of installation, maintenance.

The specific embodiment

Among the figure: 1, balladeur train, 2, the chute cell body, 3, baffle plate, 4, level advances regulation device, 5, the balladeur train lid, 6, the cylinder seat, 7, guidance set, 8, bolt, 9, plate, 10, cylinder cap.

As shown in Figure 1, the chute structure of coal plough or conveyer comprises chute cell body 2, baffle plate 3, also comprises balladeur train 1, and balladeur train 1, chute cell body 2, baffle plate 3 adopt to be welded to connect and be integrated the composition chute; Balladeur train lid 5 is the ingredient of balladeur train 1, and balladeur train lid 5 is arcuate shape, and the above is welded with plate 9; Plate 9 is bolted on the balladeur train 1; Balladeur train covers the B face of 5 below semicircle nests and cooperates installation with the half nose circle A face that guidance set 7 on the balladeur train stretches out, be bolted, can carry out relative rotary motion in certain limit, with bolt 8 plate 9 is fixed on the balladeur train 1 during complete machine work, realize the fixing of balladeur train lid, upset balladeur train lid 5 during maintenance, convenient inspection and maintenance to chain and guidance set.

Chute baffle 3 sides are welded with cylinder seat 6, and cylinder seat 6 first halves are provided with spherical heavy nest, and Lower Half is that tradition is passed the otic placode shape; Cylinder cap 10 is bolted with cylinder seat 6, forms semiclosed spheroid; Advance regulation device 4 to stretch out hydraulic cylinder to level and play fixing and supporting role, utilize level to advance regulation device 4 to its active force, upper and lower adjusting chute, the planing level of assurance coal-cutting machinery.

Wherein: balladeur train is cast-weld construction; The cylinder seat is casting; Guidance set is casting.
