BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grease tester, and more particularly to a grease tester for a crane rail that applies grease to a rail mounted on a large-sized crane for industrial, heavy industry, port logistics, and the like.

Generally, organic, solid organic, and spray oil are also applied to the rails of large cranes (30TON or more). However, due to the wear of running rails and wheels in use, I do not. As crane running rails and wheels wear progresses rapidly, maintenance and replacement costs increase, so manual application of grease to the side of the rails from the rails is often repeated.

In connection with this, reference may be made to the following Korean Utility Model Registration No. 0270097 (Prior Art 1) and Korean Patent Publication 2004-0013649 (Prior Art 2).

Thus, the effect of preventing a safety accident occurring during manual operation as well as a slipping phenomenon of a traveling wheel is expected.

Prior Art 2 discloses an air compressor for supplying compressed air; A mixing part for supplying a coating agent and a coating agent mixed with compressed air by mixing and supplying compressed air; A nozzle unit connected to the mixing unit and spraying the coating agent mixed with the compressed air onto the rail or the wheel; And the like. Therefore, it is expected that the cost reduction due to the reduction of labor costs and the reduction of friction and wear of wheels and rails will reduce the cost of power.

However, according to the above-mentioned prior art, since the work is uniformly performed without considering the abrasion condition of the rails, there is room for improvement in terms of improving the overall efficiency of the coating.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes an apparatus for applying grease to a rail for the running of a crane. Since the large crane adjacent to the ceiling of the ordinary process line and installed via the girder 10 is always operated for the loading / unloading of the heavy load product, the forward and backward movements are repeated on the rail 15. Since the rail 15 for the crane is damaged by high load, the grease is finely applied to fill the damaged and damaged surface, thereby remarkably reducing the wear rate of the rail side and the wheel, thereby sufficiently extending the replacement period of the traveling wheel, State can be maintained.

The main body 20 according to the present invention is a structure having a grease bar 24 and a pump 26 on a base 21. The main body 20 is fixed so as to move to the girder 10 at the same time since it is preferable to apply the non-powered running method. The grease bar 24 may be mounted on the base 21 or mounted on the girder 10 as shown in Fig. In any case, a stable supporting state is maintained through the tank holder 23. [ A coil spring, a piston, a packing, and the like are mounted inside the grease cylinder 24, and a charging nipple, a ball valve, and the like are mounted on the lower surface. A cam pump is preferred as the pump 26 fixed to one side of the base 21, but is not limited thereto. The grease barrel 24 and the pump 26 are connected using a knitting yarn hose 28 of a standard product.

According to the present invention, the coating means 30 for applying the grease of the grease reservoir 24 to the rails has a pair of opposed main wheels 35 on the base 21. Two main wheels 35 are disposed in a state of being opposed to each other on the rear side of the base 21 with respect to the running direction. The main wheel 35 is formed in a divided structure using an aluminum alloy, and has a plurality of spray holes 36 through which grease is sprayed on the circumferential surface. The main wheel 35 is formed in a trapezoidal shape when viewed from the side, and has an inclined outer peripheral surface. Since the inclined surface of the main wheel 35 is in direct contact with the rail 15, wear resistance and heat resistance can be coated.

As a detailed configuration of the present invention, the coating means 30 rotatably supports the main wheel 35 via each of the wheel arms 31, and the wheel arm 31 rotates in the posture of the main wheel 35 And a posture adjuster (33) for changing the posture of the user. Referring to FIGS. 1 and 2, a pair of main wheels 35 are symmetrically coupled via respective wheel arms 31. As shown in FIG. The width of the left and right swinging of the main wheel 35 is elastically (automatically) adjusted via a tension spring (not shown) between the wheel arm 31 and the main wheel 35. The posture adjuster 33 may include a portion for adjusting the angle of contact between the main wheel 35 and the rail, as well as a portion for adjusting the left and right swinging of the main wheel 35.

The main wheel 35 of the coating means 30 is characterized in that the injection hole 36 and the applicator 37 are arranged alternately in the same straight line on an inclined circumferential surface. Referring to FIGS. 2 and 4, the spray hole 36 and the applicator 37 are repeatedly arranged on the inclined surface of the main wheel 35. FIG. The applicator 37 uses a material excellent in abrasion resistance, oil resistance, heat resistance and flexibility, and guides the grease discharged from the injection hole 36 to spread widely on the side surface of the rail. The spray hole 36 is about 6 mm in diameter when the girder 10 takes into consideration the moving speed.

On the other hand, although omitted in the drawing, the applicator 37 is not limited to the same straight line as the injection hole 36, but may be additionally attached on a straight line spaced downward. In this case, the added coating material 37 can be formed in a continuous form without being interrupted. An annular packing for blocking the rise of the grease can be added to the upper side of the applicator (37).

According to the present invention, the guide means (40) has a guide wheel (44) on the base (21) so as to align the posture of the main wheel (35) with respect to the rail. 3, the guide wheel 44 is mounted on the base 21 via the LM guide 42 on the front side with respect to the running direction. The guide wheel 44 using urethane is brought into contact with the upper surface of the rail to absorb the impact, thereby maintaining the posture alignment of the main wheel 35 to induce an even coating state.

As a detailed configuration of the present invention, the induction means (40) is characterized by connecting the guide wheel (44) and the pump (26) in a concentric manner to generate a pumping force in a non-power source. A camshaft 27 and a coupling are mounted inside the guide wheel 44 and connected by a pump 26. The pump 26 is pumped through a rotary shaft which is connected to the guide wheel 44 in a concentric manner and has a reducer for controlling the injection pressure and a control valve 38 for controlling the injection amount inside and outside. The grease having passed through the regulating valve 38 in the pump 26 is supplied to the main wheel 35 via the hose 28.

The induction means 40 includes an LM guide 32 for horizontally movably supporting the wheel arm 31 of the main wheel 35 opposed to the wheel arm 31, The double spiral shaft 47 and the double spiral shaft 47 which are connected to each other by the rotation of the spiral shaft 47. [ Referring to FIG. 4, as a modification of the induction means 40, a state in which the LM guide 32, the double spiral shaft 47, and the gap adjuster 48 are further mounted on the base 21 is illustrated. The LM guide 32 is fixed to the base 21 and slidably supports the wheel arm 31. The double spiral shaft 47, which is rotatably supported on the base 21, is engaged with the left and right spirals of the left and right wheel arms 31, respectively. The gap adjuster 48 connects the bevel gear and / or the worm gear to the motor to apply the driving force to the double spiral shaft 47. When the normal and rotational driving force is applied to the interval adjuster 48, the interval between the opposing main wheels 35 is adjusted in real time.

Referring to FIG. 3, a pair of sensing wheels 45 are installed in front of the guide wheel 44 via the respective piezoelectric sensors 55. FIG. The sensing wheel 45 generates a signal indicative of a shock caused by deformation or damage of the rail while moving the rail 15 in contact with both surfaces thereof, and sends it to the controller 52 to be described later.

According to the present invention, the control means (50) controls the coating operation of the coating means (30) with an established algorithm. The control means 50 is based on a microprocessor, a memory, and a controller 52 equipped with an input / output interface. The pump 26, the control valve 38, and the interval adjuster 48 described above in FIG. 5 are connected to the output interface via the driving unit 58. FIG.

The control means 50 includes a controller 52 for storing and executing the set algorithm, a level sensor 54 for detecting a change in liquid level of the grease bottle 24, A piezoelectric sensor 55 for detecting a variation, and a CCD camera 56 for photographing a rail and a grease application state. The level sensor 54, the piezoelectric sensor 55, and the CCD camera 56 are connected to the input interface of the controller 52. The level sensor 54 can detect the state in which the amount of grease reaches the lower limit at one side of the tank holder 23. [ The piezoelectric sensor 55 detects a pressure fluctuation caused by deformation or damage of the rail as described above. The CCD camera 56 photographs the front and rear states before and after the grease application, and also photographs the operating states of the above-described components.

As an example of the operation, the grease EP0 is filled in the grease barrel 24, is seated in the tank holder 23 and the valve is opened, so that the grease is delivered to the pump 26 by the piston operation in the grease bar 24, While the main body 20 is moving along the rail of the crane, the camshaft in the pump 26 is rotated by the rotation of the guide wheel 44 to transmit the grease, And when the damage is detected through the piezoelectric sensor 55, the amount of spraying through the main wheel 35 and the control valve 38 is calculated through timing calculation, Variable is performed in real time.

Thus, it is possible to effectively achieve the object of eliminating the waste of grease during the coating process and maintaining a uniform coating state. Even if the viscosity of the grease changes during the winter season and the summer season, constant application is possible at all times.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
