Concrete embodiment
Below in conjunction with accompanying drawing internal combustion engine locomotive connecting-rod bolts dedicated hydraulic spanner of the present utility model is described in detail, Fig. 1 is the structural representation of internal combustion engine locomotive connecting-rod bolts dedicated hydraulic wrench of the present utility model, Fig. 6 is whole structure figure, this dedicated hydraulic spanner comprises a column wrench body 1, a universal Oil-pressure joint that is installed with on wrench body 1 (has only been drawn a hickey in the accompanying drawing 1, do not have the picture joint), oil sector links together by universal Oil-pressure joint and wrench body 1, (accompanying drawing 6), end at wrench body 1 has a hydraulic jack 3, and hydraulic jack 3 communicates with universal Oil-pressure joint; One piston 4 that is connected with piston rod 14 is housed in the hydraulic jack, and this piston rod 14 stretches out from the other end of oil cylinder 3, and is linked together with drive plate 6 rotationally by a pin 41; Have a ratchet gripper shoe 5 to be fixed on the above-mentioned wrench body 1, this drive plate 6 is contained on the ratchet gripper shoe 5; A ratchet 8 is housed on drive plate, this ratchet 8 and ratchet 7 engagements that are contained on the ratchet gripper shoe, the sleeve 71 of six sides in one is housed in the ratchet 7, and this sleeve rotates and rotates along with ratchet, in wrench body 1 another stomidium, an end of aiming at piston rod 14 is equipped with a back-moving spring 9, when the oil sector release, back-moving spring 9 pushes up back original position with piston rod 14, finishes a reciprocating stroke, and so forth, ratchet is constantly swung.Ratchet with the engagement of ratchet in one-directional rotation, drive above-mentioned sleeve 71 and rotate and tighten or unclamp the connecting-rod bolts that are enclosed within the sleeve.
Also has an extension bar 10, one end of this bar 10 is installed in an end of wrench body 1 with thread connecting mode, therefore extension bar can center on radially 360 ° of rotations of wrench body, also can adjust along the wrench body axial length, the other end at extension bar 10 is equipped with a stop sleeve 11, and this sleeve is hinged on the boosting-rod 10 with a bearing pin 12, this sleeve 11 is enclosed within on another bolt that need not become flexible or tighten, and plays a strong point.
At an end and the ratchet gripper shoe 5 homonymy places of wrench body 1 near Oil-pressure joint, the gripper shoe 2 of one strong point of exerting oneself as spanner is being set, this gripper shoe 2 is under the situation of not using boosting-rod 10, tighten or when unclamping bolt, it is abutted on the plane of connecting rod one side, play a firmly strong point.Referring to Fig. 2, Fig. 4..
Fig. 2 is when tightening the A bolt of connecting rod, does not use lengthening stop sleeve 11 and when using self gripper shoe, self gripper shoe is leaned against on the plane of connecting rod, from the oil pipe pressurization A that tights a bolt.
When Fig. 3 is the A bolt of loosening connecting rod, adopt the lengthening stop sleeve, this jacket casing on the bolt of connecting rod B, is enclosed within ratchet carriage 71 on the bolt A, add oil pressure, unclamp bolt A from oil pipe.
