Description

Rubber tube balancer

Technical Field

The invention relates to the field of oiling machines, in particular to a rubber tube balancer.

Background

The rubber tube balancer is mainly used for retracting and releasing a rubber tube of the oiling machine, and the potential energy of a spring accumulated in the spring inside the balancer and the gravity of the suspended rubber tube are balanced to enable the rubber tube to be in a suspended state, so that friction between the rubber tube and the ground is avoided, and the appearance of the whole oiling machine is more attractive. When the oil gun is used for oiling, the rubber tube pulls the steel wire rope, the steel wire rope drives the balancer rotating wheel to rotate to release the steel wire rope, and oiling is carried out after the steel wire rope reaches a proper length; after the oil is added, the spring potential energy accumulated by a spring in the rubber tube balancer drives the balancer rotating wheel to rotate, and the steel wire rope is recovered and wound on the balancer rotating wheel after the balancer rotating wheel rotates, so that the aim of recovering the rubber tube of the oil gun is fulfilled.

In the prior art, chinese utility model patent document No. CN207142825U discloses a rubber tube balancer with a damping structure, which automatically decelerates when an oil gun finishes adding oil and the rubber tube is recovered, thereby avoiding danger caused by too fast recovery speed of the rubber tube. A rubber tube balancer with a damping structure comprises a balancer rotating wheel, a mounting shaft, a clockwork spring and a traction rope, wherein the balancer rotating wheel is movably sleeved in the middle of the mounting shaft and is in running fit with the mounting shaft, the traction rope is wound on the balancer rotating wheel, one end of the clockwork spring is fixed on the mounting shaft, the other end of the clockwork spring is fixed on the balancer rotating wheel, a rotary damper is installed on the balancer rotating wheel, an inner ring of the rotary damper is fixedly sleeved on the mounting shaft, and an outer ring of the rotary damper is fixedly connected with the balancer rotating. It makes the rubber tube retrieve speed reduction through the rotatory damping that sets up, but this kind of rubber tube equalizer is difficult to control the tensile length of rubber tube when using, is difficult to stop the work of equalizer promptly after the rubber tube pulls out certain length, is difficult to make the rubber tube stable under the prerequisite that does not receive the effort of equalizer stop on certain pull-out length, and this just makes the staff need always to the rubber tube application of force, prevents that the rubber tube from retracting under the effect of equalizer, and it is inconvenient to use.
