Abstract
The utility model discloses a chain tensioner comprising a tensioner body, elephant-feet, bolts, lock nuts, nuts, a hook and a screw. A guide groove is arranged at the upper side surface of the tensioner body. A connecting groove is arranged at one end face of the body and the elephant-feet are arranged in the groove. The tensioner body and the elephant-feet are inserted into the holes of the groove and the holes for mounting the elephant-feet respectively and are mounted to form flexible connection by bolts locked by the lock nuts. Screw is arranged between two ends of the tensioner body. The threaded-in end of the screw is threaded into the groove and mounted on the tensioner body with nuts and gaskets. A cylindrical boss on the other end of the screw contacts with end face of the tensioner body. A guide boss for the bolthole at the end of the hook matched with the screw is arranged in the guide groove of the tensioner body and is mounted with the guide groove with clearance fit. The utility model comprises the tensioner body, the elephant-feet, bolts, lock nuts, a hook and a screw, which has simple structure and is easy to install and use.
Description
Technical field
The utility model relates to a kind of mechanical tensioning device, especially a kind of tightening device that is used for freight container lifting chain.
Background technology
At present, in the freight container lifting process, image angle attaching parts around generally directly tangling above the container top with the colligation chain by suspension hook lifts by crane, because colligation chain on each image angle and the length between the loop wheel machine hook and angle can not be just the same, during the lifting beginning, colligation chain on loop wheel machine hook and each image angle is in relaxed state, when loop wheel machine hook upward movement, when earlier the colligation chain on each image angle being strained, at this moment the tensioning degree of every colligation chain is all different, continues lifting, tends to cause the overbalance of freight container, even the suspension hook above the freight container comes off the serious consequence that causes freight container to land.Therefore, need a kind of colligation chain tension means, to solve the tensioning problem of colligation chain in the freight container lifting.
Summary of the invention
The technical problems to be solved in the utility model provides the tensioner of colligation chain in the lifting of a kind of freight container, and this tensioner has simple in structure, and characteristics are installed, easy to use etc.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of chain tensioning device, comprise tensioner body, resemble pin, bolt, jam nut, nut, gib head, screw rod has a guide groove along its length on the tensioner body upper side, have the connection groove on the end face, groove is built-in with and resembles pin, and tensioner body flexibly connects with resembling in the pin connecting bore with bolt insertion recess hole with resembling pin, and with jam nut bolt is pinned, between tensioner body two ends screw rod is installed, the precession end of screw rod puts in behind the groove to contact with tensioner body with the nut shimming and is connected, and the dome pylon on the screw rod other end contacts with the tensioner body end face, revolves the gib head of joining mutually with screw rod, its gib head screw guide ledges places in the guide groove of tensioner body, and with the guide groove free-running fit.
Rolled reticulate pattern on the screw rod one end epirelief cylinder table outside cylinder.Be provided with the outer-hexagonal stud head above the screw rod dome pylon.The round platform that resembles pin 1 is with to resemble the pin attaching parts suitable.
The utility model resembles pin by tensioner body, bolt, and jam nut, gib head, screw rod is formed, and is simple in structure, installation, easy to use.Just the colligation chain on the gib head being tightened up or loosen toward double action as long as drive gib head by the screw rod rotation, can satisfy the freight container lifting fully to the slack-free requirement of colligation chain, is a kind of very practical tool.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As Fig. 1, shown in 2, a kind of chain tensioning device, comprise tensioner body 7, resemble pin 1, bolt 2, jam nut 3, nut 4, gib head 6, screw rod 8, have along its length on tensioner body 7 upper sides and have connection groove 13 on 9, one end faces of a guide groove, groove 13 is built-in with and resembles pin 1, tensioner body 7 with resemble pin 1 usefulness bolt 2 and insert recess holes and resemble flexible connection in the pin connecting bore, and with jam nut 3 bolt 2 is pinned, between tensioner body 7 two ends screw rod 8 being installed, the precession end of screw rod 8 puts in groove 13 backs and contacts with tensioner body with nut 4 shimmings 5 and be connected, dome pylon 10 on screw rod 8 other ends contacts with tensioner body 7 end faces, has rolled reticulate pattern on screw rod 8 one end epirelief cylinder tables 10 outside cylinder and has been used for manual rotary screw.Being provided with outer-hexagonal or square stud head 11 above the screw rod dome pylon 10 is used for being matchedly connected with manual wrench or air nutsetter or power-operated wrench.Revolve the gib head 6 of joining mutually with screw rod 8, its gib head screw guide ledges 12 places in the guide groove 9 of tensioner body, and with guide groove 9 free-running fits.The round platform that resembles pin 1 is with to resemble pin attaching parts 16 suitable.
When the utility model uses (shown in Figure 3), earlier tensioner 100 is stretched out to certain-length,, then the pin 1 that resembles of tensioner 100 is put into and resembled pin attaching parts 16 so that tighten up chain.
Tension tensioner 100 and chain 15 will a joint nearest apart from the hook of tensioner 100 be placed on the hook of tensioner 100 (shown in Figure 4).
