Description
Technical field
The present invention relates to the centering means that a kind of pipeline robot is used, especially a kind of six arm roller centering means.
Background technique
When pipeline robot is walked in the duct, for reducing friction, need to connect centering means at two ends, centering means is installed by the sleeve pipe traction robot as oil field.Existing centering means has spring sheet and eight arm rolling wheel centralizers, and wherein, spring sheet centering effect is poor, and easy-rupturing, maintenance cost is high, can not adapt to caliber on a large scale; Although eight arm rolling wheel centralizer centering effect are better, also can adapt to caliber on a large scale, complex structure, installation inconvenience, and there is comparatively large eccentricity moment, key position easy-rupturing during operation.
Summary of the invention
For overcoming the deficiency of existing centering means, the utility model provides a kind of six arm roller centering means, and during this six arms roller centering means operation, centering effect is good, can adapt to caliber on a large scale, structure is simple, and installation, maintenance is convenient, reduce eccentric moment, bearing capacity is stronger.
Technological scheme of the present invention is: this six arms roller centering means comprises axis, axis two ends have been threaded connection left connecting base and right connecting base, arm seat is arranged symmetrically with inside connecting base, the built-in Rectangular Spring of arm seat, Rectangular Spring two ends have end cap and ram seat respectively, ram seat side pressing edge cylindrical sleeve, sleeve passes arm seat, be enclosed within axis, left and right support arm is hinged on sleeve, roller is arranged on support arm by the first screw, roller is free to rotate, three push rods in ram seat are with three support arm contacts, arm seat and end cap are fixed on axis by the second screw.Support arm has waist shaped hole with sleeve connection end, has the fixing pin be fixed on sleeve in waist shaped hole, can limit the range of movement of support arm; Axis two ends are connected with left and right connecting base, and left and right connecting base has internal and external screw thread respectively, for other devices of connecting tube robot.
The invention has the beneficial effects as follows: this six arms roller centering means is owing to have employed such scheme, promote ram seat by Rectangular Spring, the push rod in ram seat promotes three pairs of support arms, realizes radial support, by roller and tube contacts, realize opening and closedown of support arm; Owing to only adopting three pairs of support arms, structure is more simple, and installation, maintenance is convenient, and in addition, the throw of eccentric of support arm is less, and during operation, eccentric moment is less, support arm and sleeve hinged place additional load less, bearing capacity is stronger; Push rod in ram seat promotes support arm and rotates around sleeve hinged place, form leverage, a small amount of displacement of ram seat is amplified through this leverage, regulate the stretching degree of support arm, because a small amount of displacement only occurs ram seat, Rectangular Spring restoring force is almost constant, and therefore this six arms roller centering means can adapt to caliber on a large scale.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the structural representation of embodiments of the invention 1.
Fig. 2 is the structural representation of embodiments of the invention 2.
The note marked in accompanying drawing: in figure, 1-axis, the left connecting base of 2-, the right connecting base of 3-, 4-arm seat, 5-Rectangular Spring, 6-end cap, 7-ram seat, 8-sleeve, 9-support arm, 10-roller, 11-first screw, 12-second screw, 13-fixing pin
Embodiment
Embodiment 1 as shown in Figure 1, this six arms roller centering means comprises axis 1, axis 1 two ends are connected with right connecting base 3 with left connecting base 2 by screw thread, in left connecting base 2 and right connecting base 3 have respectively, outside thread, for other devices of connecting tube robot, arm seat 4 is arranged symmetrically with inside connecting base, the built-in Rectangular Spring 5 of arm seat 4, Rectangular Spring 5 two ends are end cap 6 and ram seat 7, ram seat 7 side clamp sleeve 8, sleeve 8 is enclosed within axis 1, pass arm seat 4, support arm 9 is hinged on sleeve 7, support arm 9 coupling sleeve 8 end has waist shaped hole, the fixing pin 13 be fixed on sleeve 8 is had in waist shaped hole, the slewing area of restriction support arm 9, roller 10 is arranged on support arm 9 by the first screw 11, roller 10 is free to rotate, arm seat 4 and end cap 6 are fixed on axis by the second screw 12.Promote ram seat 7 by Rectangular Spring 5, the push rod in ram seat 7 promotes three pairs of support arms 9, realizes radial support, by roller 10 and tube contacts, realizes opening and closedown of support arm 9.Owing to only adopting three pairs of support arms 9, structure is more simple, and installation, maintenance is convenient, and in addition, the throw of eccentric of support arm 9 is less, and during operation, eccentric moment is less, support arm 9 and sleeve 8 hinged place additional load less, bearing capacity is stronger.
As shown in Figure 2, the push rod in ram seat 7 promotes support arm 9 to embodiment 2, and rotate around sleeve 8 hinged place, three forms leverage, and support arm 9 and sleeve 8 hinged place are balance pivot.The a small amount of displacement of ram seat 7, amplifies through leverage, causes the radial displacement that support arm 9 is larger, due in operation process, ram seat 7 displacement amount is little, and therefore the change of Rectangular Spring 5 restoring force is very little, centering means power placed in the middle is almost constant, and therefore this six arms roller centering means can adapt to caliber on a large scale.
