Description
Technical field
The utility model belongs to traveling mechanism of coal mining machine field, particularly relates to a kind of mobile roof support.
Background technology
Coal-winning machine is the key equipment during machine worked mine is produced, and mobile roof support is the critical piece of traveling mechanism of coal mining machine.Mobile roof support refers to that coal-winning machine inner on rack rails or tooth bar on a conveyor has walking gear to lead the support of walking along rack rails near goaf side with installing, because heavy duty, work plane condition limit, between mobile roof support and rack rails, fretting wear is serious, sometimes even can and rack rails between " very stiff and demanding ", wearing and tearing can be even more serious in this case; Particularly wide-angle work plane, wide-angle face upward adopt or bow adopt time, cause mobile roof support in use not wear-resisting, long service life then 1 to 2 months, short then 7 to 15 days, change that mobile roof support is consuming time needs 4-8 hour in addition, have a strong impact on the operating efficiency of coal-winning machine, significantly increase cost of production.
Summary of the invention
The utility model provides a kind of mobile roof support for solving mobile roof support life-span low technical problem.
Technical solution adopted in the utility model is: a kind of mobile roof support, comprises mobile roof support body, and described mobile roof support body comprises spigot surface and installing plate; Described installing plate is provided with installing hole; Described spigot surface is provided with some through slots; Wearing layer is provided with in described through slot; Described wearing layer just fills up described through slot.Wearing layer has good wearability can, be embedded in spigot surface by through slot, wearing layer and mobile roof support body producing balanced forces, can alleviate the wearing and tearing between ore deposit machine walking mechanism leading truck and rack rails, active force can not be made again entirely to act on wearing layer and cause wearing layer to come off.
As preferably, described wearing layer and the connected mode of spigot surface are that laser cladding welds.Laser cladding technology is a kind of new technology along with Development of Laser Technology gets up, and as coating preparation and the forming technique of advanced person, has been widely used in the surface peening of metallic element with reparation; Compare with traditional welding method, laser cladding welding has that heat affected zone is little, surface quality good, bond strength advantages of higher.Wearing layer laser cladding is soldered to mobile roof support body by the utility model, can effectively improve mobile roof support abrasion resistance, increase the service life.
As preferably, described wearing layer cross section is trapezoidal.Laser cladding welding operation is convenient in trapezoid cross section, and bond strength is high.
As preferably, trapezoidal base angle, described wearing layer cross section is 45 degree.More general trapezoid cross section, the trapezoid cross section that base angle is 45 degree is more easy to operate, and bond strength is higher.
As preferably, described wearing layer thickness is 10mm.
As preferably, described through slot is at least 3.Wherein 2 are arranged on spigot surface end face, and 1 is arranged on spigot surface bottom surface because end face and bottom surface even more serious compared with flank wear, side can not be arranged, the position of through slot is exactly the position of wearing layer, is arranged on 3 positions of wearing and tearing the most serious with rack rails by wearing layer, alleviates wearing and tearing.
As preferably, described mobile roof support body is integrated casting, and spigot surface adjacent surface angle is equipped with the curving of castings, curving of castings radius 15mm.The little meeting of the curving of castings causes stress to concentrate, thus reduces mobile roof support bulk strength, reduction of service life; The curving of castings is crossed conference and is destroyed spigot surface cross sectional shape, even causes the curving of castings and the direct contact of rack rails.
As preferably, the end face of described installing plate is dihedral angle; The rib of described dihedral angle is described installing hole vertical direction center line, the described dihedral angle number of degrees are 170 degree ~ 175 degree, can twist about direction of travel after mobile roof support is installed, to ensure when bearing large resistance, walker can carry out small adjustment on traffic direction.
As preferably, described installing hole is strip hole, and two ends are semicircle arcuation, makes installation shaft can horizontal direction twisting in hole.Sprocket wheel and gear are arranged between two installing holes, not straight or when having other obstructions at rack rails, straight line portion out wider than axle makes installation shaft slightly can twist between installing hole, thus realize guide function, and be unlikely to and rack rails " very stiff and demanding ", and then alleviate wearing and tearing, increase the service life.
The advantage that the utility model has and good effect are: because the utility model adopts as above technical scheme, enhance the abrasion resistance properties of ore deposit machine walking mechanism leading truck, and reduce frictional force, significantly improve physical life, reduce and change number of times, enhance productivity, reduce cost of production.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the present embodiment is a kind of mobile roof support, comprises mobile roof support body 1, and described mobile roof support body 1 comprises spigot surface 2 and installing plate 5; Described installing plate 5 is provided with installing hole 3; Described mobile roof support body 1 is integrated casting, and spigot surface adjacent surface angle is equipped with the curving of castings, curving of castings radius 15mm; Described installing hole 3 is strip hole, and two ends are semicircle arcuation, and installation shaft horizontal direction can be twisted in hole; The end face of described installing plate 5 is dihedral angle; As shown in Figure 3, the rib of dihedral angle is described installing hole 3 vertical direction center line, the described dihedral angle number of degrees are 174 degree, angle opening is inner to installing plate 5, can twist about direction of travel after mobile roof support is installed, to ensure when bearing large resistance, walker can carry out small adjustment on traffic direction; Described spigot surface 2 is provided with 3 through slots, and wherein 2 at end face, 1 in bottom surface because comparatively flank wear is more serious end face and bottom surface; Described through slot inner laser deposit welding is connected to wearing layer 4; Described wearing layer 4 just fills up described through slot; The cross section of described through slot and wearing layer 4 cross section are the trapezoidal of the 45 degree of high 10mm in base angle, and namely wearing layer 4 thickness is 10mm.
Considering cost and properties of product, the present embodiment does not arrange wearing layer in spigot surface side; But in actual production, whether can arrange wearing layer by selective guide side as required, therefore wearing layer position can not as to restriction of the present utility model, and no matter whether spigot surface side arranges wearing layer, all belongs within the utility model protection domain.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
