Abstract
The utility model relates to a replacer for a sleeve roller chain. The replacer is composed of a screw rod I, a screw rod II, a wrench bit, a nut I on the screw rod I, a pulling claw I, a nut II on the screw rod II and a pulling claw II, wherein the wrench bit is arranged between the screw rod I and the screw rod II; the pulling claw I is connected with the nut I; the pulling claw II is connected with the nut II; and a screw thread turning direction of the screw rod I is opposite to that of the screw rod II. With the adoption of the replacer, the roller chain can be exchanged conveniently; the labor intensity is reduced; one person can exchange a coarse pitch chain usually, therefore, the work efficiency is improved, and a repairing space is not required.
Description
Technical field
The utility model relates to a kind of dismantling device, specifically belongs to the replacer that is used for dismounting sleeve-barrel roollr chain.
Background technology
The sleeve-barrel roollr chain is a kind of mechanical transmission part of standard; Be used with roller chain wheel, it is comparatively compact to have physical dimension, characteristics such as transmission efficiency height; Be widely used in that centre-to-centre spacing is big, transmission narrow space, average ratios transmission accurately, occasions such as environment is abominable, low-speed heave-load.Slippage phenomenon takes place apart from elongated in the meeting envoy after the wearing and tearing of sleeve-barrel roollr chain, must upgrade roller chain when serious.Only need pull down when changing chain wherein that a joint movable joint can take off the whole piece chain from sprocket wheel, same, during installation movable joint is loaded onto, fix.Because roller chain dangles and two roller chain wheels between, fixedly between chain link and the flexible connection relative pulling force is arranged, inconvenience very during the dismounting hunting link; When particularly changing the coarse pitch chain, because of its from great, movable joint and fixedly between the chain link internal force big; Owing to still do not have by instrument at present, can only rely on manual work to accomplish during dismounting, generally need at least 2 people dismounting; And labour intensity is big, uses duration.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, convenient to operation, and labour intensity is little, need be few with personnel, and the replacer of the sleeve-barrel roollr chain that work efficiency is high.
Realize the technical measures of above-mentioned purpose:
A kind of replacer of sleeve-barrel roollr chain; It is: it is made up of the spanner position between screw rod one, screw rod two, screw rod one and the screw rod two, the nut one on the screw rod one, the pulling claw one that is connected with nut one, the nut two on the screw rod two, the pulling claw two that is connected with nut two, and screw rod one is opposite with the thread rotary orientation of screw rod two.
It is characterized in that: the spanner position is at least three limits and is solid.
It is characterized in that: being shaped as arc or falling trapezoidal shape of pulling claw one, pulling claw two.
The characteristics of the utility model are to be convenient for changing the operation of roller chain, reduce labour intensity, and when particularly changing the coarse pitch chain, a common people can operate, and has improved work efficiency, and to the space for maintenance no requirement (NR).

The structural representation that Fig. 3 is pulling claw one or a pulling claw two when trapezoidal
Among the figure: 1-screw rod one, 2-screw rod two, 3-spanner position, 4-nut one, 5-pulling claw one, 6-nut two, 7-pulling claw two.
The specific embodiment
Do below in conjunction with accompanying drawing and to further describe:
A kind of replacer of sleeve-barrel roollr chain: spanner position 3 integral body between screw rod 1, screw rod 22 and screw rod 1 and the screw rod 22 are processed as one; Spanner position 3 is solid four limits or five limits or hexagon; Screw rod 1 is opposite with the hand of spiral of screw rod 22, promptly one left-handed, a dextrorotation; To be screwed on the screw rod 1 through the nut engaged 1 that is threaded with screw rod 1, and be welded to connect arc or the pulling claw of falling the trapezoidal shape 1 in the employing of the lower end of nut 1; To be screwed on the screw rod 22 through the nut engaged 26 that is threaded with screw rod 22, and be welded to connect arc or the pulling claw of falling the trapezoidal shape 27 in the employing of the lower end of nut 26.
Use principle
Earlier chain is installed on the sprocket wheel during use; When using chain to draw horse; Arc or the pulling claw of falling the trapezoidal shape 1 are threaded to the outer end of screw rod 1 through pairing nut 1, also arc or the pulling claw of falling the trapezoidal shape 27 are threaded to the outer end of screw rod 22 through pairing nut 26; Then with arc or the pulling claw of falling the trapezoidal shape 1 and pulling claw 27 two terminations of the insertion roller chain that need connect with movable joint respectively; Spanner is aligned in 3 places, spanner position; And rotating screw bolt 1 and screw rod 22 ends; Chain is tensioned to the position that suitable movable joint is loaded onto, loads onto movable joint and fixing, can accomplish chain and more change jobs.During dismounting, program is identical, and just drawing the effect of horse this moment is to eliminate hunting link and the fixing internal stress between the chain link, makes movable joint be easy to take off.
Claims (3)
1. the replacer of a sleeve-barrel roollr chain; It is characterized in that: it is made up of the spanner position between screw rod one, screw rod two, screw rod one and the screw rod two, the nut one on the screw rod one, the pulling claw one that is connected with nut one, the nut two on the screw rod two, the pulling claw two that is connected with nut two, and screw rod one is opposite with the thread rotary orientation of screw rod two.
