Abstract

The utility model relates to a tackle for a tractor, which is used in the construction for erect a pole in the power transmission engineering. The utility model is mainly composed of a chain wheel which is driven by the tractor to drive a groove teeth in the form of speed changing, a ring buckle type chain and a rotary joint on the head end of the ring buckle type chain. The utility model solves the problems that the existing steel cable tackle has long total cable and large weight and is easy to twist because of the reinforcing force; the utility model has convenient transportation and raises the work efficiency.

Description

A kind of tractor strand mill

This reality is novel to have related to a kind of tractor strand mill, and the particularly a kind of tractor strand of using in the construction of power transformation vertical rod tower mill that send belongs to the power construction field of mechanical technique.

At present, China's power transmission engineering Lifting Method in Pole Tower Integral Hoisting group is stood facility work, adopt wire rope pulley group lifting technology always, promptly use the strand grinding rope that is wrapped on the tractor strand mill to connect two group 5 and take turns the scooter group, connect total traction steel rope of cable stand up pole and electric pole again, add total pull rope, this device is 1 ton of weight nearby.Carrying, loading and unloading are all inconvenient, and steel rope abrasion is big, poor durability, need regular frequent replacing, need before particularly using repeatedly the elongation of wire rope pulley group to be shortened by manpower, very require great effort, and wire rope is at tractive or put self torsion big (being commonly called as " energetically ") when restricting, and safety in utilization is relatively poor.

The purpose of this utility model is exactly for solving the above-mentioned defective of tractor strand mill in the construction of electric power transmission vertical rod tower, and design provides a kind of carrying of being convenient to, and it is short, easy to use to put the rope time, the chain type tractor strand mill that safety is good.

The purpose of this utility model is to realize like this, be with the gearbox of power transmission shaft through worm drive one as the tractor of power, have check mechanism on it, the sprocket wheel of a band chain groove is housed on the power transmission shaft of gearbox, twine the ring-buckling type chain on it as pulling rope, its tractive head end is provided with an anti-rotary connector of turning round and shaft tower is directly led connects.

The utility model has the advantages that to have solved the contradiction that original wire rope " energetically " reverses manpower and the time of having avoided assembly pulley tractive wire rope to fall to restrict and wasted repeatedly again.Improve operating efficiency, increased safety in utilization.

Accompanying drawing 1, the utility model master looks schematic diagram;

Accompanying drawing 2, the utility model are overlooked (office is cutd open) schematic diagram;

Accompanying drawing 3, sprocket wheel A-A cross-sectional schematic;

Accompanying drawing 4, rotary connector B-B are analysed and observe (amplification) schematic diagram.

Retouch concrete structure of the present utility model in detail below in conjunction with accompanying drawing.

Grind with novel tractor strand this pass, form by the gearbox 2 that is contained on the tractor 1, the power of gearbox 2 is input as a worm screw 3 that links to each other with driving power (drive power and generally use tractor), drive output chain rivet 6 through worm gear 4 and change-speed gearing group 5, output check mechanism 7 is housed on the gearbox 2, one end of this chain rivet 6 is equipped with chain wheel 8, twine traction ring-buckling type chain 9 on it, have the groove tooth 10 that matches with the latch closure of chain 9 on the chain wheel 8, for prevent that chain 9 from reversing when drawing or put rope, its traction end can digest the swivel joint 11 that reverses through one and connect traction gib heads 12.Use for ease of multiple construction occasion, the other end of this chain rivet 6 also can be equipped with identical chain wheel 8 and chain 9, and wire rope strand mill 13 perhaps is housed.

Claims

1, a kind of tractor strand mill, it is characterized in that: form by the gearbox (2) that is contained on the tractor (1), the power of gearbox (2) is input as a worm screw (3) that links to each other with driving power, drive output chain rivet (6) through worm gear (4) and change-speed gearing group (5), output check mechanism (7) is housed on the gearbox (2), one end of this chain rivet (6) is equipped with chain wheel (8), twine traction ring-buckling type chain (9) on it, have the groove tooth (10) that matches with the latch closure of chain (9) on the chain wheel (8), for prevent that chain (9) from reversing when drawing or put rope, its traction end can digest the swivel joint (11) that reverses through one and connect traction gib head (12).

2, a kind of tractor strand mill as claimed in claim 1 is characterized in that described chain rivet (6) other end also is equipped with chain wheel (8), reaches chain (9) and swivel joint (11), gib head (12).

3, a kind of tractor strand mill as claimed in claim 1 is characterized in that the other end of described chain rivet (6) is equipped with wire rope strand mill (13).
