Description
Technical field: the present invention relates to a kind of motor vehicle repair equipment, relate in particular to a kind of device that is used to lift engine when overhauling automobile engine.
Background technology: well-known, when automobile engine is carried out large repairs, all engine to be disassembled from vehicle frame usually; Yet because the engine volume is big, Heavy Weight, installation site complexity, installing space are narrow and small in addition, therefore need many people to cooperate in dismounting or installation process, and not only labour intensity is big but also operation is very inconvenient, even the danger that injures the maintenance personal by a crashing object is arranged.For this reason, the utility model patent that Granted publication number is respectively " CN2441611Y ", " CN201224395Y ", " CN2106106U " discloses three kinds of supports that are used to dismantle engine or main reducing gear respectively, though these devices can reduce the maintenance personal labour intensity, reduce to injure by a crashing object maintenance personal's risk, but because adjustable free degree is few, therefore operate underaction, to be suitable for vehicle less.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of flexible to operation, dismountable lifting arm with multiple degrees of freedom for automobile engine that can adapt to multiple vehicle.
To achieve these goals, the present invention by the following technical solutions: it comprises the base that is provided with road wheel, be located at support arm on this base, be located at anchor clamps on this support arm, promote the leading screw of described support arm motion; Be fixed with column on the base, described support arm by be located at support on this column, be hinged on Y-shaped master connecting-rod and two slave connecting rods on this support, the anchor clamps mounting blocks that is hinged on the master connecting-rod and the slave connecting rod other end constitutes, the divergent ends of leading screw and master connecting-rod is hinged; Be provided with gear drive in the support, this gear drive is by being hinged on gear-box in the support, being located at driven gear and pinion in this gear-box, being located in the gear-box with the driving gear of driven gear engagement, with the gear ring of pinion, being located on the leading screw and the feed screw nut of fixedlying connected with gear ring constitutes by handle; Described anchor clamps by be installed in sleeve on the anchor clamps mounting blocks by axle, last cross-bar and following cross-bar, the contiguous block that is set in cross-bar and two ends, the following cross-bar left and right sides at two ends constitute up and down to be inserted into this sleeve respectively.
Be provided with fastening screw between support and the column; Be provided with extension spring between last cross-bar and the following cross-bar; Nut is installed on the anchor clamps mounting blocks by rotating shaft, and the ball screw that is located in the nut keeps in touch with the Universal-head that is enclosed within down the cross-bar bottom.
Compared with the prior art, therefore the present invention not only can reduce maintenance personal's labour intensity, but also can reduce maintenance personal's quantity owing to adopted technique scheme; Because it is equal multi-directionally rotation of support arm, anchor clamps and base or swing, therefore flexible to operation, operating efficiency is high.In addition, owing to can come to realize being connected with the engine of different automobile types by the contiguous block that replacing is provided with different installing holes, so the present invention can adapt to the automobile engine repairing of multiple vehicle.
