Abstract
The utility model discloses a kind of Modular belts roller type top iron device, including top iron main body, roller group and the different apical ring of several external diameters, apical ring is detachably arranged in the iron main body of top, roller group is arranged on the bottom of top iron main body, and roller group can drive top iron assembly to be slided on slide rail during propulsion and return；Can the different apical rings of the diameter assembling of tubing according to used in construction.The utility model can select the apical ring of various outer diameter according to the difference of construction pipe diameter used, and be installed in the iron main body of top, improve and push up the main acrosome versatility of iron, so as to reduce equipment cost.Meanwhile, roller group can drive top iron assembly to be slided on slide rail during propulsion and return, it is to avoid existing frequently-used roller-less formula top iron bottom surface and the propulsion mode of slide rail straight surfaces brought into contact, reduce contact area and frictional force, improve efficiency of construction.
Description
Technical field
The utility model is related to a kind of Modular belts roller type top iron device, belongs to engineering underground pipe-driving pipeline construction equipment
Technical field.
Background technology
In existing push pipe pipeline construction, different top iron main body and apical ring, versatility is respectively configured in different tubing
Relatively low, equipment is not fully utilized so that cost is raised.Moreover, existing pipe jacking equipment top iron is without roller, top iron bottom surface is direct
Slided on balladeur train, frictional force is very big and promotes inconvenience under special circumstances, reduces fltting speed, reduces the effect of construction
Rate.
The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of Modular belts roller type top iron device,
Top iron main body versatility can be improved, equipment cost is reduced, while reducing top iron promotes frictional force, efficiency of construction is improved.
To achieve these goals, a kind of Modular belts roller type top iron device that the utility model is used, including top iron
Main body, roller group and the different apical ring of several external diameters, the apical ring are detachably arranged in the iron main body of top, the roller
Group is arranged on the bottom of top iron main body, and roller group can drive top iron assembly to be slided on slide rail during propulsion and return；
Can the different apical rings of the diameter assembling of tubing according to used in construction.
Preferably, the top iron main body is provided with the screwed hole along different-diameter circle distribution, and apical ring is installed by screw a
In the iron main body of top.
Preferably, the roller group is symmetrically mounted on the both sides of top iron lower body part, and roller group includes four rolling.
Preferably, the roller in the roller group is arranged on top iron lower body part by axle sleeve, bearing pin, baffle plate and screw b.
Preferably, it is interference fits between the outer ring of the axle sleeve and roller centre bore, between the inner ring and bearing pin of axle sleeve are
Gap coordinates.
Compared with prior art, the utility model can according to construction used in pipe diameter difference, in identical top iron master
The apical ring of various outer diameter is installed on body, improves the top main acrosome versatility of iron to reduce equipment cost.Meanwhile, roller group is being pushed away
Top iron assembly can be driven to be slided on slide rail during entering and returning, so as to avoid existing frequently-used roller-less formula top iron bottom
Face and the propulsion mode of the straight surfaces brought into contact of slide rail, reduce contact area and frictional force, improve efficiency of construction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 front view.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of Modular belts roller type top iron device, if including top iron main body 1, roller group 4 and
The dry different apical ring 6 of external diameter, the apical ring 6 is detachably arranged in top iron main body 1, and the roller group 4 is arranged on top iron
The bottom of main body 1, roller group 4 can drive top iron assembly to be slided on slide rail during propulsion and return；Can be according to construction
The diameter of tubing used assembles different apical rings 6 in the iron main body 1 of top.
Preferably, the screwed hole along different-diameter circle distribution can be provided with the top iron main body 1, apical ring 6 passes through screw
A5 is arranged in top iron main body 1.Wherein, the apical ring different from external diameter of the screwed hole in iron main body 1 is pushed up to use cooperatively.
Preferably, the roller group 4 is symmetrically mounted on the both sides of the bottom of top iron main body 1, and roller group 4 includes four rolling.
It is of course also possible to be two, or it is multiple.
Preferably, the roller in the roller group 4 is arranged on top iron main body by axle sleeve 3, bearing pin 2, baffle plate 8 and screw b7
1 bottom.Axle sleeve 3 is anti-wear sleeve, further improves its service life.
Preferably, it is interference fits between the outer ring of the axle sleeve 3 and roller centre bore, inner ring and the bearing pin 2 of axle sleeve 3 are
Gap coordinates.
From said structure, the utility model can according to used in construction pipe diameter difference, in identical top iron master
The apical ring of various outer diameter is installed on body, improves the top main acrosome versatility of iron to reduce equipment cost.Meanwhile, roller group is being pushed away
Top iron assembly can be driven to be slided on slide rail during entering and returning, so as to avoid existing frequently-used roller-less formula top iron bottom
Face and the propulsion mode of the straight surfaces brought into contact of slide rail, reduce contact area and frictional force, improve efficiency of construction.
