Detailed Description
As shown in fig. 1-2, the hoisting hoist comprises a hoisting drum, a base 2 and a pair of fixing plates 3, wherein the pair of fixing plates 3 are fixedly connected to the base 2, and the hoisting drum is hinged between the two fixing plates 3;
the steel cable protection system comprises a dust cover 4 and two lubricating oil assemblies 20, wherein the dust cover is wrapped outside the hoisting cylinder and is fixedly connected between the two fixing plates; the lower part of the dust cover is provided with a pair of strip-shaped through holes for penetrating steel cables; like this, can simply, effectually avoid the cable wire surface to adsorb the dust through the dust cover, effectively solve because of the dust caking influences the problem of headstock gear normal operating. The invention has the characteristics of exquisite structure, good dustproof effect and good use stability on the whole.
The lubricating oil assembly 20 is positioned below the elongated through hole 40 and comprises a cylinder 201, an oil tank 202, a suspender 203, a piston 204 and a pair of supporting springs 205, the cylinder 201 is hollow and is slidably connected to the base 2, and through holes 2010 for penetrating steel cables are formed in the top surface and the bottom surface of the cylinder 201; the steel cable passes through the cylinder before entering the hoisting cylinder and after being sent out of the hoisting cylinder, and the cylinder can freely slide on the base along with the transverse displacement of the steel cable during the winding and unwinding;
the oil tank 202 is slidably connected to the inner wall of the cylinder 201, and the pair of supporting springs 205 respectively abut against the top surface and the bottom surface of the oil tank, so that the oil tank 202 is suspended in the middle of the cylinder 201; the top surface of the barrel 201 is further provided with an oil filling hole, the suspension rod 203 penetrates through the oil tank 202 and is fixedly connected below the oil filling hole, an oil filling channel 2030 communicated with the inside of the oil tank 202 is formed in the suspension rod 203, the piston 204 is fixedly connected to the bottom end of the suspension rod 203, the side surface of the piston 204 is attached to the inner wall of the oil tank 202, one side, facing the axis of the through hole 2010, of the oil tank 202 is provided with an oil outlet 2020, and the oil outlet 2020 and the piston 204 are located on the same horizontal plane. When in use, the following conditions can be divided: 1. the steel cable is static: at the moment, the oil outlet hole is consistent with the height of the piston, so that the oil outlet hole is blocked by the piston, and the oil cannot flow out of the oil tank; 2. accelerating the movement of the steel cable: after the steel cable obtains the linear velocity, the oil tank is driven to move upwards or downwards through friction force, so that the oil outlet holes and the pistons are staggered, and the oil tank sprays oil to the surface of the steel cable to lubricate the steel cable; 3. the steel cable moves at a constant speed: similarly, because the steel cable still has the linear velocity, the oil tank still sprays oil to the surface of the steel cable; 4. the steel cable moves to a standstill in a decelerating manner: along with the gradual reduction of the linear speed of the steel cable, the oil tank moves upwards or downwards under the action of the restoring force of the supporting spring, so that the piston gradually moves to a position with the same height as the oil outlet hole, and oil outlet is stopped.
In summary, in each process of winding and unwinding the steel cable, the oil tank sprays oil to the surface of the steel cable to lubricate and maintain the steel cable, and the oil spraying can be automatically stopped when the steel cable is static, so that the use cost is reduced. The steel cable lubrication and maintenance device has the advantages of good steel cable lubrication and maintenance effects, stable work and high reliability on the whole.
The piston 204 is provided with at least one oil passing hole 2040. The space above and below the piston is communicated, so that the oil outlet smoothness is effectively improved.
And a control valve is arranged in the oil filling hole.
A plurality of anti-slip strips are arranged on the surface of one side of the oil tank 202, which faces the axis of the through hole, and a plurality of ball heads 2011 arranged towards the anti-slip strips are connected to the inner wall of the barrel 201. Thereby ensure through the bulb that the cable wire is laminated on the surface of oil tank all the time to effectively strengthen the frictional force between cable wire and the oil tank through the antislip strip, thereby make the work of lubricant subassembly more stable, reliable.
