Abstract
The utility model relates to a special tool for tensioning chains, which is capable of conveniently and effectively replacing the chains and comprises two clamping claws for inserting and clamping rollers of the chains, wherein the two clamping claws are connected through that a nut is matched with a screw thread screw rod; the nut and the screw thread screw rod are between the two clamping claws; the nut is matched with the screw thread screw rod in the mode that one clamping claw is provided with the nut, and the other clamping claw is provided with a bracket; a bearing is contained in the bracket; the screw thread screw rod is movably installed on the bracket through the bearing; one end of the screw thread screw rod is matched with the nut, and the other end of the screw thread screw rod is provided with a screw thread head. The utility model has the advantages of reduced labor intensity, short maintenance time and enhanced maintenance efficiency. The special tool for tensioning chains is capable of rapidly clamping the rollers of the chains, is matched with a standard ratchet wrench to use, rapidly tensions the chains and is convenient for maintenance personnel to assemble and disassemble buckles of the chains.
Description
Technical field
The utility model relates to a kind of tension chain specific purpose tool that can change chain easily and effectively, this tension chain specific purpose tool can block chain roller fast, be used with the standard ratchet spanner, strain chain rapidly, be convenient to the button that connects that the maintenance personal installed, dismantled chain.
Background technology
In industrial production line, chain drive is the kind of drive of using always, often needs to install not only long but also heavy chain; Or the chain after long-time the use, because factor such as wearing and tearing, pitch are elongated must be changed.When installing or change not only long but also heavy chain, two statures that two of chain need be separated are moved to together as possible, and the two stature installing holes distance that keeps chain to separate is the pitch of chain just, so that the button that connects of chain is installed, makes chain become the circle of a sealing.But because the influence of other jig of installing on the deadweight of chain and the chain when changing chain, all is near the strength of a plurality of staff installation, dismounting to be finished in the tension of chain picking-up or dependence iron wire in the past.Very the effort, consuming time.Particularly in the assembly room that kiln factory is arranged, as: colored bulb enterprise, iron and steel enterprise etc., the overhaul of the equipments time seizes every minute and second.Tension chain specific purpose tool can be very effective minimizings maintenance time, improve equipment operation rate, the raising comprehensive production efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of and can reduce labour intensity, shortens maintenance time, improves the tension chain specific purpose tool of maintenance efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: comprise two claws that insert and block chain roller, two claws by between the two nut and the cooperation of threaded screw rod be connected.The cooperation of described nut and threaded screw rod is meant that a claw is provided with nut, another claw is provided with the support that contains bearing, and threaded screw rod is movably arranged on the support by bearing, and an end of threaded screw rod matches with nut, and the other end is a thread head.Also be provided with sliding guide between two claws.Claw is the semicircle pawl that adapts with the chain roller radius.
The utlity model has following good effect:
1, can strain chain fast, the semicircle pawl that adapts with the chain roller radius is arranged, the semicircle pawl can firmly block chain roller, and claw comes off in the time of can not straining chain.
2, designed nut, threaded screw rod, contain bearing, outer six sides tensioning mechanism for combination, be used with the ratchet spanner and the sleeve of standard, finish the task of quick tension chain.
3, designed sliding guide mechanism, made also to have reduced the frictional resistance in the tension process by the special-purpose formation of tension chain rock-steady structure.
4, on the adjustment threaded screw rod, increased bearing, reduced friction, made and adjust very light and fast.For this device is not in use twisted, designed the slide-and-guide bar adjusting under the threaded screw rod, increased linear bearing, make the semicircle pawl on this device do rectilinear motion and do not twist along guide post.
5, the ingenious semicircle pawl that adapts with the chain roller radius that designed can firmly block chain roller, and claw comes off in the time of can not straining chain.
6 with compared with modes such as staff or iron wires in the past, use tension chain specific purpose tool installing, when changing chain, more can saving the maintenance personal, can reduce maintenance cost.
7, be suitable for and install, change heavy reel chain and the urgent flow production line of requirement maintenance time, can help to improve maintenance efficiency.
8, use tension chain specific purpose tool, install, when changing chain, more save the maintenance personal, can reduce maintenance cost than alternate manner.
Description of drawings
Fig. 1 is the use schematic diagram of the utility model when chain is installed.
Fig. 2 is the use schematic diagram of the utility model when the dismounting chain connects button.
The specific embodiment
As shown in Figure 1, 2, the utility model comprise two 6, two claws 6 of claw that insert and block chain roller by between the two nut 1 and the cooperation of threaded screw rod 2 be connected.The cooperation of described nut 1 and threaded screw rod 2 is meant that a claw 6 is provided with nut 1, another claw 6 is provided with the support 3 that contains bearing, and threaded screw rod 2 is movably arranged on the support 3 by bearing, and an end of threaded screw rod 2 matches with nut 1, and the other end is a thread head 4.Also be provided with sliding guide 5 between two claws 6.Claw 6 is the semicircle pawl that adapts with the chain roller radius.
1, chain is installed, as shown in Figure 1,2 claws of tension chain specific purpose tool are inserted respectively near two statures that are mounted chain, and make chain roller be in the claw semicircle pawl, the fast clockwise threaded together leading screw of use standard ratchet spanner and sleeve, chain will be strained rapidly, till distance is suitable, with chain loose joint button chain is connect.
2, remove chain, as shown in Figure 2, adjust the width of tension chain specific purpose tool claw, 2 claws are inserted respectively near the two ends of chain loose joint button, and make chain roller be in the claw semicircle pawl, and using the fast clockwise threaded together leading screw of standard ratchet spanner and sleeve, chain will be strained rapidly, at this moment loose joint buckle is easy to a chain loose joint button and removes in relaxed state.
Fig. 1. in: 1 is nut, and 2 is threaded screw rod, and 3 for containing the support of bearing, and 4 is outer six sides, and 5 is sliding guide, and 6 is the semicircle pawl of chain jamming bar roller, and 7,8 are respectively two statures of chain.
