Description
Technical field
The utility model relates to a kind of steel bar girder internode apart from adjusting device, specifically be used for to regulate the steel bar girder step distance.
Background technology
Along with expanding economy, steel bar girder is more and more universal in the application of industries such as oil, shipbuilding, building, digging, public way, the energy and decoration.
The steel bar girder a complete set of equipment is used for forming the steel bar girder floor support plate at base plate, is applied to industry and civilian construction and structure.When concrete floor slab construction, steel bar girder is layed on the beam, to bear concrete deadweight and working load; Simultaneously, steel bar girder is used as the permanent cage of reinforcement of floor again.
The steel bar girder internode is for the device of adjusting the truss step distance apart from adjusting device.Traditional steel bar girder internode can be followed the movement of stepping mechanism and move apart from being adjusted because adjusting motor and reduction box, adds that mobile speed is very fast, causes the wearing and tearing of rotating shaft and key easily, the formation gap; More seriously, because violent vibrations can damage motor and reduction box.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of steel bar girder internode apart from adjusting device, is used for the step distance of stable regulation steel bar girder, has avoided the mobile wearing and tearing that cause in the stepping process.
The technical scheme that provides according to the utility model, the steel bar girder internode comprises stepping oil cylinder, swing arm down, mounting bracket, reduction box, top link, stepping push rod, adjusts motor and eccentric shaft apart from adjusting device, the stepping oil cylinder fixes on the frame by hinges fixing, and mounting bracket connects frame by bolt.Reduction box and adjustment motor are fixed on the mounting bracket.Top link upper end is by the bearing pin stepping push rod that is rotationally connected, and following swing arm rear end connects the stepping oil cylinder by bearing pin, it is characterized in that: by bearing setting-up eccentricity axle, eccentric shaft one end connects the reduction box output on the frame.The input of reduction box is connected with the adjustment motor.Top link is contained on the eccentric shaft by bearing holder (housing, cover), and the top link lower end is provided with first journal stirrup and second journal stirrup, and following swing arm upper end is provided with the 3rd journal stirrup and the 4th journal stirrup.First journal stirrup connects the 3rd journal stirrup by bearing pin, and second journal stirrup connects the 4th journal stirrup by bearing pin.
Described mounting bracket is provided with the waist hole.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, rationally; The mobile wearing and tearing that cause in the stepping process have been avoided; Safe and reliable, easy to maintenance.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: swing arm under 1-stepping oil cylinder, the 2-, 3-mounting bracket, 4-reduction box, 5-top link, 6-stepping push rod, 7-adjust motor, 8-eccentric shaft, 9-first journal stirrup, 10-second journal stirrup, 11-the 3rd journal stirrup, 12-the 4th journal stirrup.
The specific embodiment
Embodiment during following the utility model is incited somebody to action by reference to the accompanying drawings is further described:
As shown in Figure 1, the utility model mainly comprises stepping oil cylinder 1, swing arm 2 down, mounting bracket 3, reduction box 4, top link 5, stepping push rod 6, adjusts motor 7 and eccentric shaft 8.
By bearing setting-up eccentricity axle 8, eccentric shaft 8 one ends connect reduction box 4 outputs on the frame 9.The input of reduction box 4 is connected with adjustment motor 7.Described reduction box 4 and adjustment motor 7 are fixed on the mounting bracket 3.Described mounting bracket 3 is provided with the waist hole, and the waist hole makes mounting bracket 3 can adjust the position in frame fixedly the time.
Top link 5 is contained on the eccentric shaft 8 by bearing holder (housing, cover), and top link 5 upper ends are by the bearing pin stepping push rod 6 that is rotationally connected.Top link 5 lower ends are provided with first journal stirrup 9 and second journal stirrup 10, and following swing arm 2 upper ends are provided with the 3rd journal stirrup 11 and the 4th journal stirrup 12.First journal stirrup 9 connects the 3rd journal stirrup 11, the second journal stirrups 10 by bearing pin and connects the 4th journal stirrup 12 by bearing pin.Following swing arm 2 rear ends connect stepping oil cylinder 1 by bearing pin.
Described stepping oil cylinder 1 fixes on the frame by hinges fixing.Described mounting bracket 3 connects frame by bolt.
Operating principle of the present utility model is: during work, the piston rod of stepping oil cylinder 1 stretches out, and promotes swing arm 2 down and rotates, and following swing arm 2 drives top link 5 again and rotates around eccentric shaft 8, and following swing arm 5 drives stepping push rod 6 again and travels forward, thereby promotes the truss stepping.When needs adjustment step pith, rotate and adjust motor 7, drive eccentric shafts 8 by reduction box 4 and rotate, after adjustment finished, eccentric shaft 8 kept these positions motionless.Are balance pivots of down swing arm 2 and top link 5 because of eccentric shaft 8, after turning over a position, the total travel of stretching out stepping oil cylinder 1 equally, the hunting range of top link 2 and following swing arm 5 changes, thereby cause stepping push rod 6 proal variable in distance, played the effect of adjusting the truss pitch.
