Description

Leveling suspender

Technical field

The present invention relates to a kind of rail welding equipment, the suspender of especially relevant hanging-welder.

Background technique

The suspender of hanging-welder is mainly comprised of with two rod assemblies that are connected on hanger hanger at present.When the strength of the suspender of this structure on the rod assembly of the left and right sides is different, just there will be welding machine out-of-level, but can not regulate level, this can the operation of butt welding machine in welding process bring very big inconvenience.China Patent No. is the suspender that 201020184223.5 document discloses a kind of adjustable mass center, it forms hanger controlling mechanism by parts such as connecting rod, nut, regulating handles, although can carry out hanger position regulation, have the shortcoming that complex structure, adjustment operation are loaded down with trivial details, be prone to stuck phenomenon.In addition, existing suspender does not have insulation function, can not be used on hanging-welder.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, adjustment operation is easy, have insulation function, be applicable to the leveling suspender that hanging-welder is used.

In order to achieve the above object, technological scheme of the present invention is: a kind of leveling suspender, comprise hanger and two rod assemblies, also there is screw rod, crossbeam and U bolt, the bottom of described hanger has connecting sleeve, connecting sleeve is enclosed within on screw rod, two adjusting nuts have been threaded on described screw rod, two adjusting nuts are pressed on respectively connecting sleeve two ends, the two ends of described screw rod are hinged with respectively a rod assembly, described rod assembly includes jaw bolt, the first nut, sleeve, screw plug, cross-over block, insulating bush and pull bar, described jaw bolt bottom has outside thread, described sleeve inner has internal thread, the internal thread of sleeve is threaded and uses the first nut check with the outside thread of jaw bolt bottom, described lower cartridge has step hole, the step head of pull bar assembles by insulating bush and step hole, in the internal thread of described sleeve, be screwed with screw plug, screw plug is pressed on cross-over block, cross-over block is pressed on the step crown face of pull bar, described pull bar bottom is fixedly connected with crossbeam, described U bolt end is also installed on crossbeam with the second nut through the jack on crossbeam.

Between described sleeve and the first nut, also clamped check washer.

On described pull bar, also cover has sheath and gland, sheath upper end and sleeve lower end offset, and sheath lower end and gland upper end offset, and gland lower end and crossbeam offset, described pull bar bottom has outside thread, and pull bar bottom through the attachment hole on crossbeam after its outside thread bottom be connected with the 3rd nut thread.

The top of described sheath is also nested with stretching out in the part outside sleeve at insulating bush.

On the jaw of described jaw bolt with the first pin-and-hole, the two ends of described screw rod are the engaging lugs with the second pin-and-hole, and engaging lug is inserted in the fork pockets of corresponding jaw bolt and by connecting pin, passes the first pin-and-hole on the jaw of jaw bolt and the second pin-and-hole of engaging lug is realized hinged.

Adopt after said structure, because the bottom of described hanger has connecting sleeve, connecting sleeve is enclosed within on screw rod, two adjusting nuts that have been threaded on described screw rod, and two adjusting nuts are pressed on respectively connecting sleeve two ends, therefore, employing part is few, simple in structure, can regulate the balance of suspender, make welding machine left and right sides frame keep level, greatly facilitate tracking and the clamp operation of welding machine in welding process; By rotating two adjusting nuts, can directly regulate the position of hanger above screw rod, to reach the length that changes the left and right sides arm of force, and then adjusting level, adjustment operation is easy, there will not be stuck phenomenon, safe and reliable; Because each rod assembly includes jaw bolt, the first nut, sleeve, screw plug, cross-over block, insulating bush and pull bar, therefore, rod assembly has insulation function again, is applicable to hanging-welder and uses.
