Description
Technical field
The utility model relates to a kind of mechanical component of fluid pressure actuator, is specifically related to a kind of eliminator.
Background technology
For a long time, the hinging pin shaft of many mining machineries all adopts matched in clearance, under normal circumstances, utilize traditional extracting tool to remove smoothly, but the connection bearing pin of many equipment but is difficult to dismounting, except every day use with safeguard the aspect factor, also relevant with method for dismounting and instrument.Traditional special-purpose bearing pin extraction method is to pass extractor by bolt to be fixed on bearing pin extraction hole, when pretightning force reaches the motion stress of bearing pin, make bolt form pretension, turn standby cap and produce pretightning force, continue to turn standby cap, utilize the tensile strength of bolt to force bearing pin to propose.This way is applicable to the dismounting of new product connecting pin, and shortcoming is only to be applicable to smooth faying face, and extraction power is little, fastening standby cap effort, and the bearing pin that runs into distortion can't be dismantled substantially.At present winning equipment towards maximizing, the integrated multifunction development, the serviceable condition of equipment affects production efficiency, and improve, the Improving Equipment maintenance service, be conducive to improve equipment operating efficiency, reduce cost of equipment maintenance.The utility model come from mine combine extractive equipment work energy connecting portion bearing pin because the reasons such as corrosion, stress deformation cause not easily detachable phenomenon, particularly to the dismounting of one direction assembling bearing pin, essential especially.
The utility model content
The purpose of this utility model is but to be difficult to the dismounting problem for the connection bearing pin of many equipment, provide a kind of simple in structure, removal force is large, easy to operate provision for disengagement.
The purpose of this utility model realizes by following technological means: a kind of eliminator, include successively connect tear pin oil cylinder, cylinder lever connecting rod, contiguous block, packing ring, nut open, contiguous block is connected on the equipment parent by bearing pin, described centre of tearing the pin oil cylinder open also is provided with through hole, described cylinder lever connecting rod is passed through by the centre of through hole, cylinder lever connecting rod one end is connected with the bearing pin that needs dismounting by contiguous block, the other end is fixed on the rear portion of tearing the pin oil cylinder open by packing ring, nut, and the described pin oil cylinder of tearing open is connected to hydraulic power unit by high-pressure oil pipe.
Described hydraulic power unit is set to the hand-hydraulic pumping plant of supercharging, includes hydraulic hand-pump and fuel tank, and described hydraulic hand-pump is the high-pressure pump that maximum pressure is 60MPa.
The described pin oil cylinder of tearing open is Hollow hydraulic cylinder, more than its cylinder diameter extends to 300mm.
Compared with prior art the utlity model has following obvious advantage: the utility model can significantly be raised the efficiency, and uses manpower and material resources sparingly; Oil cylinder in effectively avoiding in the past designing should be placed on bearing pin bottom and problem that space is extremely restricted, extracts direction at bearing pin to use this device can reach promising result, and the range of application of eliminator is greatly enhanced; Also there is the advantages such as simple in structure, that removal force is large, easy to operate.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, the 1-nut, the 2-packing ring, 3-tears the pin oil cylinder open, 4-cylinder lever connecting rod, 5-contiguous block, 6-bearing pin, 7-equipment parent.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is described in further detail:
A kind of eliminator as shown in Figure 1, include successively connect tear pin oil cylinder 3, cylinder lever connecting rod 4, contiguous block 5, packing ring 2, nut 1 open, contiguous block 5 is connected on equipment parent 7 by bearing pin 6, described centre of tearing pin oil cylinder 3 open also is provided with through hole, described cylinder lever connecting rod 4 is passed through by the centre of through hole, cylinder lever connecting rod 4 one ends are connected with the bearing pin that needs dismounting by contiguous block 5, the other end is fixed on the rear portion of tearing pin oil cylinder 3 open by packing ring 2, nut 1, and the described pin oil cylinder 3 of tearing open is connected to hydraulic power unit by high-pressure oil pipe.This device, after all being connected firmly, being handled hydraulic hand-pump and is started to buy oil to tearing open in pin oil cylinder 3, oil by fuel tank through the hand-hydraulic pump pressure to the bottom of tearing pin oil cylinder 3 open, the piston of tearing pin oil cylinder 3 open stretches out, after propping up the outside of bearing pin, when pressure is greater than the extraction power of bearing pin, bearing pin is pulled out.
Described hydraulic power unit is set to the hand-hydraulic pumping plant of supercharging, includes hydraulic hand-pump and fuel tank, and described hydraulic hand-pump is the high-pressure pump that maximum pressure is 60MPa.Arrange like this, the utility model can improve removal force greatly.Eliminator hollow core oil cylinder adopts advanced design concept, changed form in the past commonly used, be applied on large cylinder diameter, very large raising dismounting pressure, while can hydraulic hand-pump reaching 23MPa, Hollow hydraulic cylinder can send 200 tons of pressure, and this ability was not having in various provisions for disengagement in the past.
The described pin oil cylinder 3 of tearing open is for Hollow hydraulic cylinder, more than its cylinder diameter extends to 300mm, the structure arranged like this is all this eliminator of adaptation and designs novel structure, be issued to satisfied stroke guarantee at minimum volume, can reach 150 tons with upward pressure when hydraulic power unit provides 10MPa with upward pressure by test, be this eliminator core component.
In a word, this eliminator goes for the dismounting that various plant equipment connect bearing pin, and the bearing pin that various ways all is difficult to dismounting particularly adapts to.All in addition in using the process of being dismantled by equipment, bearing pin is extracted direction and is forbidden to have personnel to exist, in order to avoid there is unsafe factor to exist.Supercharging is progressive, during operation, wants steadily, to observe at any time the bearing pin state.
This eliminator can combine the pluses and minuses of domestic and international various provision for disengagement and method according to the actual needs in China's machinery maintenance, through improvement, Development and design form repeatedly.Each modular construction compactness, the cooperation science is tight, durable in use, not fragile.
In a word, the utility model provide a kind of simple in structure, removal force is large, easy to operate provision for disengagement.The above; it is only a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
