Embodiment 1

[0028] During the deviation process of the wheels of the trolley towed by the quay crane, each wheel train will generate additional axial force due to the difference in deflection angle. This axial force will increase with the increase of the deviation displacement, and force the trolley Buckling deformation occurs in the steel structure of the trolley frame, and when the axial force reaches or exceeds the friction force between the wheel and the track, the wheel of the trolley axially slides back to the initial position. Repeatedly, the steel structure of the trolley frame is subjected to long-term alternating loads, and fatigue cracking is prone to occur.

[0029] During the process of the trolley wheel gnawing on the rail, there is a strong extrusion effect between the wheel rim and the side of the track, and because of the high friction coefficient between the wheel and the track, it produces a great running resistance to the operation of the equipment. According to the me...

Embodiment 2

[0040] Such as figure 2 As shown, the present invention provides a minimum oil quantity lubrication device, including: an oil film thickness detection unit 3 , a control unit 4 , a trolley encoder 5 and a minimum oil quantity lubrication coating unit 6 . For convenience of description, the figure also includes a track 1 and a trolley wheel 2 .

[0041] The oil film thickness detection unit 3 is electrically connected with the control unit 4, and is used to receive the work order of the control unit 4, detect the oil film thickness of the trolley wheel tread and send the signal of the oil film thickness to the control unit 4;

[0042] The dolly encoder 5 is electrically connected to the control unit 4, and is used to collect pulse signals in the running of the dolly and send the pulse signals to the control unit 4;

[0043] The micro-oil lubrication coating unit 6 is electrically connected to the control unit 4, receives the pulse signal from the control unit 4 and outputs lu...

Embodiment 3

[0055] Such as Figure 6 As shown, the micro oil volume pump includes: electromagnetic coil 17, ejector rod 18, valve seat 19, plunger 20, oil inlet chamber 21, return spring 22, oil hole 23, plunger sleeve 24, working chamber 25, check valve 26, oil outlet cavity 27 and compression spring 28.

[0056] The electromagnetic coil 17 is installed on the end surface of the valve seat 19, and the ejector rod 18 is installed between the inner iron core of the electromagnetic coil 17 and the plunger 20, arranged coaxially. The plunger 20 is assembled in the sliding sleeve of the plunger sleeve 24, and there is a good fit gap between the two to seal the oil. The return spring 22 is assembled between the plunger sleeves 24 of the plunger 20 . The one-way valve 26 at the rear end of the plunger sleeve 24 closes the oil outlet under the action of the compression spring 28 , and now the oil in the working chamber 25 communicates with the oil inlet chamber 21 through the oil hole 23 . Th...

Abstract

The invention provides a tiny-oil-amount lubrication method and device. The method comprises the following steps of 1, periodically detecting the oil film thickness of a wheel tread of a trolley, andconducting calculation, so that the mean value of the oil film thickness is obtained; 2, comparing the mean value of the oil film thickness with a preset threshold value range of the oil film thickness, and determining a set value of the operation distance of the trolley; and 3, obtaining the operation distance of the trolley, comparing the operation distance with the set value of the operation distance of the trolley, and determining whether to start tiny-oil-amount lubrication or not according to a comparison result. By means of the method, optimum oil film coverage can be achieved; and compared with manual lubrication, the tiny-oil-amount lubrication method has great advantages with respect to the lubricating effect, oil control, environmental pollution, manual maintenance cost control,personnel security and the like.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a method and device for lubricating with a small amount of oil. Background technique [0002] The running power of the quay crane traction trolley is wire rope traction. Due to the deviation of the left and right traction wire rope adjustment, the horizontal inclination angle of the trolley wheel, the straightness of the trolley track and the difference in the height difference between the two sides of the track, the traction trolley produces lateral movement during the front and rear running on the track. When offset, the wheel rim and the end surface of the track produce a large axial extrusion force, and this friction phenomenon is commonly referred to as the "rail gnawing" phenomenon. The current technical measure is to use the horizontal wheel to limit the running track of the traction wheel, and change the extrusion sliding friction into rolling friction, but it ...
