Abstract
The utility model discloses a kind of adjustment for door machine luffing rack lower compression roller to change specific purpose tool, is made up of fixed part and supporting part, and the supporting part is a metal tube, and the upper port closing of the metal tube, lower port is opening；The support is local to be included：Arc sheetmetal and 2 metal cylinders, the length of the arc sheetmetal is more than the length of lower compression roller, and the recess of the arc sheetmetal is upward, 2 metal cylinders are packed in the both sides of arc sheetmetal upper surface respectively, and the middle part of the lower surface of the arc sheetmetal and the upper end of the supporting part are fixedly mounted with；Wherein, the diameter of the arc sheetmetal is more than the external diameter of door machine luffing rack lower compression roller, and specific purpose tool small volume is changed in adjustment of the present utility model, it is not take up service clearance, it is high with the use of stability with jack, reduces operating personnel's labor intensity, improves maintenance efficiency.
Description
Technical field
The utility model belongs to a machine technical field, relates in particular to a kind of tune for door machine luffing rack lower compression roller
Whole replacing specific purpose tool.
Background technology
Whether 40 tons of door machine luffing rackwork operations are steady, are largely determined by rack pressure roller and regulate whether
Position, need to change in time once pressure roller breaks down, otherwise will have a strong impact on the running stability of jib lubbing mechanism, even result in
The failure of other mechanisms.Rack pressure roller is made up of a upper pressure roller and former and later two lower compression rollers, and the wherein adjustment of lower compression roller is changed,
It is larger particularly to change work difficulty.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of for door machine luffing rack lower compression roller
Specific purpose tool is changed in adjustment, and specific purpose tool is changed in the adjustment can facilitate maintenance activity, improves maintenance efficiency.
The technical solution of the utility model is carried out by following technical proposals.
Specific purpose tool is changed in a kind of adjustment for door machine luffing rack lower compression roller, is made up of fixed part and supporting part, institute
It is a metal tube to state supporting part, and the upper port closing of the metal tube, lower port is opening；The support is local to be included：Curved metal
Plate and 2 metal cylinders, the length of the arc sheetmetal are more than the length of lower compression roller, and the recess court of the arc sheetmetal
On, 2 metal cylinders are packed in the both sides of arc sheetmetal upper surface, the middle part of the lower surface of the arc sheetmetal respectively
It is fixedly mounted with the upper end of the supporting part；Wherein, the diameter of the arc sheetmetal is more than the external diameter of door machine luffing rack lower compression roller.
In the above-mentioned technical solutions, the height of the supporting part is 120mm, external diameter 140mm.
In the above-mentioned technical solutions, the height that specific purpose tool is changed in the adjustment is 190~210mm.
Compared to prior art, it is of the present utility model adjustment change specific purpose tool small volume, be not take up service clearance, its with
Jack is high with the use of stability, reduces operating personnel's labor intensity, improves maintenance efficiency.
Brief description of the drawings
Fig. 1 is the structural representation that specific purpose tool is changed in adjustment of the present utility model.
Wherein, 1 is fixed part, and 1-1 is metal cylinder, and 1-2 is arc sheetmetal, and 2 be supporting part.
Embodiment
Specific purpose tool is changed to adjustment of the present utility model below in conjunction with the accompanying drawings to be described in detail.
As shown in Figure 1, it is made up of fixed part 1 and supporting part 2, supporting part 2 is a metal tube, the upper port of the metal tube
Closing, lower port are opening；Support is local to be included：Arc sheetmetal 1-2 and 2 metal cylinder 1-1, arc sheetmetal 1-2's
Length is more than the length of lower compression roller, and arc sheetmetal 1-2 recess is upward, and 2 metal cylinder 1-1 are packed in arc respectively
The both sides of shape metallic plate 1-2 upper surfaces, the middle part and the upper end of supporting part 2 of arc sheetmetal 1-2 lower surface are fixedly mounted with；Wherein,
Arc sheetmetal 1-2 diameter is more than the external diameter of door machine luffing rack lower compression roller.
Wherein, the height of supporting part 2 is 120mm, and specific purpose tool is changed in external diameter 140mm, adjustment of the present utility model
Highly it is 190~210mm.
Specific purpose tool small volume is changed in adjustment of the present utility model, easy to carry, especially in the relatively narrow and small luffing in space
The use of herringbone body panel is extremely convenient, and its application method is as follows：The specific purpose tool is installed when carrying out demolition, installation operation to lower compression roller
(the installation on mandril of lifting jack：Push rod is stretched into the metal tube and withstood under the metal tube top surface from the lower port of metal tube
Portion), jack is jacked up during dismounting makes fixed part (upper surface) be contacted with each other with lower compression roller, i.e., fixed part can be lifted and pushed
Roller, jack is withdrawn after pressure roller shaft to be removed, lower compression roller is pulled down immediately；Lower compression roller is placed on to the arc gold of fixed part during installation
Belong on plate, jack is moved to lower compression roller installation position, slowly jack up the push rod of jack, lower compression roller is risen into installation site
Afterwards, you can installation pressure roller shaft.Because the arc sheetmetal for lifting position uses designed arc-shaped appearance, lower compression roller is set to be kept thereon
Stable, whole disassembly process lower compression roller is not in the situation of rolling or relative movement, and jack only needs one man operation, effect
Rate also significantly improves.
Exemplary description is done to the utility model above, it should explanation, do not departing from core of the present utility model
In the case of the heart, any simple deformation, modification or other skilled in the art can not spend creative work etc.
The scope of protection of the utility model is each fallen within replacing.
