Description
Technical field
The utility model belongs to maintenance tool field, particularly a kind of 80 tons of crane hydraulic oil pipe special tool for services.
Background technology
80 tons of wheel-mounted cranes are hoister in large tonnage of PORT OF TIANJIN, because the service life of machinery is long, a lot of gin pole hydraulic oil pipe is aging, the seepage once oil pipe breaks, must change, but oil pipe design is at gin pole box inside, workman does not have enough service clearances, general instrument cannot get at oil connection position, for addressing this problem, needs the dismounting requirement meeting oil pipe according to a kind of special instrument of the design feature development and design of machinery.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of 80 tons of crane hydraulic oil pipe special tool for services.
The utility model realizes by the following technical solutions:
80 tons of crane hydraulic oil pipe special tool for services are made up of torque arm and spanner, and described torque arm and spanner are structure as a whole, and described torque arm becomes 90 degree of angles with spanner; Described torque arm is hexagonal bar construction; Described spanner is open-end wrench.
In technique scheme, the length of described torque arm is 1300-1800mm, is preferably 1500mm.
In technique scheme, wide (a) of described torque arm is 20mm.
In technique scheme, the opening of described open-end wrench is wide is 20mm.
Using method: first, the gin pole of 80 tons of cranes is regained completely, level is put into gin pole and props up on thick stick, then the gin pole rear end cap of 80 tons of cranes is opened, expose the oil pipe that gin pole drives oil cylinder, by specific purpose tool along the direction embedding oil connection slowly damaging oil pipe, twist hexagonal steel from casing outside adjustable wrench, until oil pipe departs from oil cylinder, complete the dismantlement work of oil pipe; When oil pipe is installed, first oil pipe is aimed at cylinder connector and make it smooth and easy connection, to carry out reinforcing with specific purpose tool to oil pipe fastening, then assemble gin pole end cap, complete current pipeline assembling operation.
The utility model has the advantage of: 1. adopt hexagonal reinforcing bar as torque arm, be convenient to reverse from gin pole casing external application spanner.2. hexagonal reinforcing bar is as torque arm, and intensity is comparatively large, avoids torque arm distortion and moment loss.3. adopt open-end wrench welding, be convenient to the embedding of instrument to screw.
The utility model is easy and simple to handle, safe and practical, structure simple, small volume, lighter in weight, effectively alleviates the labour intensity of operating personnel, convenient working, can meet the dismounting process requirement of the gin pole oil pipe of 80 tons of cranes well.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the top view of Fig. 1,
Fig. 3 is the left view of Fig. 1,
Fig. 4 is the cross sectional representation of the torque arm in the utility model.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with specific embodiment.
As illustrated in the accompanying drawings from 1 to 3,80 tons of crane hydraulic oil pipe special tool for services involved by the utility model are made up of torque arm 1 and spanner 2, and described torque arm 1 and spanner 2 are structure as a whole, described torque arm 1 and spanner 2 one-tenth 90 degree of angles;
Described torque arm 1 is hexagonal bar construction, and it is long is 1300-1800mm, is preferably 1500mm.
As illustrated in the accompanying drawings from 1 to 3, the wide a of described torque arm 1 is 20mm.
Described spanner 2 is open-end wrench, and its opening is wide is 20mm.
Preparation method of the present utility model: first preparing a long 1500mm model is that the hexagonal reinforcing bar and of 20 is the open-end wrench of 20mm, then open-end wrench is bent into the right angle of 90 degree from root part of handle along transverse plane, finally the handle of open-end wrench and hexagonal reinforcing bar is welded together in parallel.
Using method: first, the gin pole of 80 tons of cranes is regained completely, level is put into gin pole and props up on thick stick, then the gin pole rear end cap of 80 tons of cranes is opened, expose the oil pipe that gin pole drives oil cylinder, by specific purpose tool along the direction embedding oil connection slowly damaging oil pipe, twist hexagonal steel from casing outside adjustable wrench, until oil pipe departs from oil cylinder, complete the dismantlement work of oil pipe; When oil pipe is installed, first oil pipe is aimed at cylinder connector and make it smooth and easy connection, to carry out reinforcing with specific purpose tool to oil pipe fastening, then assemble gin pole end cap, complete current pipeline assembling operation.
The utility model has the advantage of: 1. adopt hexagonal reinforcing bar as torque arm, be convenient to reverse from gin pole casing external application spanner.2. hexagonal reinforcing bar is as torque arm, and intensity is comparatively large, avoids torque arm distortion and moment loss.3. adopt open-end wrench welding, be convenient to the embedding of instrument to screw.
The utility model is easy and simple to handle, safe and practical, structure simple, small volume, lighter in weight, effectively alleviates the labour intensity of operating personnel, convenient working, can meet the dismounting process requirement of the gin pole oil pipe of 80 tons of cranes well.
Above exemplary description is done to the utility model; should be noted that; when not departing from core of the present utility model, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection domain of the present utility model.
