Description
TECHNICAL FIELD
[0001] The utility model relates to port cargo handling technical field especially relates to a crane lubricant's periodic feeding device. BACKGROUND
[0002] The port portal crane is the core equipment in the port cargo handling process, and undertakes the core task of efficient transfer and handling of goods. As the hub link of port operation, its operation efficiency directly affects the overall throughput capacity and operation rhythm of the port. Safe operation is the basis of port operation, which can effectively prevent equipment failure, personnel casualties and other risks, and ensure the continuity and stability of port operation. Through centralized oil supply, block monitoring and other advanced technologies, accurate maintenance and real-time monitoring of the equipment are realized, maintenance cost is reduced, and equipment service life is improved.
[0003] In the use of the existing port portal crane, because the lubricating oil will fail due to sun exposure or continuous friction during the pulling process of the steel wire rope, the friction at the hoisting structure of the steel wire rope will increase. This increased friction will accelerate the wear of the surface of the steel wire rope, causing the steel wire rope to become thin, the surface to be ground flat, and the carrying area to be reduced, ultimately reducing the carrying capacity of the steel wire rope. Moreover, the aggravation of wear will also cause stress concentration of the steel wire inside the steel wire rope, increasing the risk of wire breakage.
[0004] To solve the problem of increased friction at the hoisting structure of the steel wire rope due to lubricating oil failure, an oiling structure is installed at the pulley, which can supplement the lubricating oil in time after the lubricating oil of the steel wire rope fails. The oiling structure can continuously supplement the lubricating oil during the operation of the steel wire rope, avoiding dry friction caused by lubrication failure. Continuous lubrication can maintain a low friction coefficient between the steel wire rope and the pulley, reduce energy loss, and improve the efficiency of the crane hoisting.
[0005] However, in the use of the existing port portal crane, the pulley is usually located at a high place, so the transportation of lubricating oil needs to be done manually. Manual transportation of lubricating oil requires frequent climbing up and down, which consumes a lot of time and physical effort. Especially when the demand for lubricating oil is large or the lubrication points are scattered, the efficiency is significantly reduced. UTILITY MODEL CONTENTS
[0006] The utility model aims at solving the shortcomings in the prior art and provides a crane lubricant periodic feeding device, which solves the problem of increased friction at the hoisting structure of the steel wire rope caused by lubricating oil failure.
[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0008] A kind of periodic feeding device of crane lubricant, including portal crane body and steel wire rope body, the top of the portal crane body is provided with guardrail, the inside of the guardrail is provided with pulley, the outer surface of the pulley is uniformly provided with four friction grooves, the inside of the symmetric two of four friction grooves is symmetrically and reversely provided with oil outlet, the friction groove and oil outlet are used to smearing lubricating oil to steel wire rope body.The smearing of friction groove and oil outlet to steel wire rope body, so as to achieve the effect of preventing the failure of lubricating oil on the surface of steel wire rope body.
[0009] As a further improvement of the utility model, the bottom end of the guardrail is fixedly connected with a bottom plate, the bottom end of the bottom plate is fixedly connected with a series hard pipe, the bottom end of the series hard pipe is fixedly connected with an oil storage tank, the oil storage tank is fixedly connected to the top end of the portal crane body, a box plug is movably connected to a corner of the top end of the oil storage tank, and a transmission oil pump is fixedly connected inside the oil storage tank. Through the transmission oil pump, the lubricating oil located inside the oil storage tank can be transmitted to the pulley.
[0010] As a further improvement of the utility model, a through hole one is formed at the top end of the transmission oil pump on the top surface of the oil storage tank, the series hard pipe is inserted into the through hole one, a series groove is formed in the inside of the bottom plate, the series hard pipe is fixedly connected to the bottom end center hole of the series groove, and two transmission pipes are fixedly connected to the ends of the series groove on the top end of the bottom plate. Through the series hard pipe, series groove and transmission pipe, the lubricating oil can be introduced into the oil storage block.
[0011] As a further improvement of the utility model, the side close to each other of the two transmission pipes is fixedly connected with an oil storage block, the side close to the transmission pipe of the oil storage block is provided with a through hole two, an oil storage groove is formed in the inside of the oil storage block, a through hole is formed in the side close to the pulley in the inside of the oil storage block, and a rotating groove is formed in the side close to the pulley of the oil storage block. Through the rotating groove, the pulley and the oil storage block can be rotatably connected.
[0012] As a further improvement of the utility model, the side close to the oil storage block of the pulley is fixedly connected with a rotating block, the two rotating blocks are rotatably connected to the inside of the two rotating grooves, and the positions of the two oil outlets are just corresponding to the positions of the two through holes. Through the position correspondence of the through hole and the oil outlet, the lubricating oil can be introduced into the inside of the oil outlet.
[0013] Compared with the prior art, the utility model has the advantages that:
[0014] 1、Through the oil storage block, pulley, friction groove and oil outlet, when the surface of the steel wire rope body has no lubricating oil, the friction force generated by the steel wire rope body in the contact between the steel wire rope body and the surface of the pulley will drive the pulley to rotate through the friction groove, at this time the rotation of the pulley will make the through hole align with the oil outlet, at this time the lubricating oil in the oil storage groove will flow to the surface of the steel wire rope body through the through hole and the oil outlet. So as to achieve the effect that the lubricating oil on the surface of the steel wire rope body is automatically smeared after failure. After the failure of the lubricating oil, the friction force between the steel wire rope body and the pulley will increase sharply, which will cause the abrasion to increase and even the wire to break. The automatic smearing can immediately supplement the oil when it fails, avoiding the accidents such as equipment jamming and breaking caused by dry friction, and ensuring the safe operation of the portal crane body. Moreover, continuous lubrication can reduce the fatigue damage and internal stress concentration of the steel wire rope body, and reduce the risk of wire breakage. Manual oil supplementing needs to stop operation, while automatic smearing can supplement oil in real time during equipment operation without interrupting work. Automatic replacement of manual high-altitude operation reduces the delay of oil supplementing caused by operation negligence or fatigue, and reduces the safety risk of personnel.
[0015] 2、Through the series hard pipe, oil storage tank, transmission oil pump, series groove and transmission pipe, the lubricating oil in the oil storage tank is transmitted to the series hard pipe through the transmission oil pump, and the hollow series connection of the series hard pipe, series groove and transmission pipe, so as to achieve the effect that the lubricating oil is automatically transmitted from the low place to the oil storage block. The traditional manual oil supplementing needs to climb to a high place, which has the risk of falling and slipping. The pumping device composed of the transmission oil pump, series hard pipe and series groove transports the lubricating oil from the low place to the pulley, which eliminates the danger of high-altitude operation without personnel climbing, and completely eliminates the danger of high-altitude operation. Moreover, manual transportation of lubricating oil may cause oil drums and tools to fall due to improper operation, which may injure the personnel or equipment below. The automatic transmission system operates in a closed manner without the risk of falling, which ensures the safety of the work below. By recording the data such as oil supplementing time and oil quantity, a more scientific maintenance plan can be made to reduce unnecessary maintenance operations. BRIEF DESCRIPTION OF DRAWINGS
