Abstract
The clamping ring lifting claw is characterized in that at least two positioning pins extending forwards are fixedly connected to a fixing frame, and the positions of the positioning pins are matched with positioning holes in a clamping ring, so that the positioning pins can be inserted into the positioning holes in the clamping ring; the fixing frame is hinged to the middle of the special-shaped pressing plate, the upper end of the special-shaped pressing plate is a lifting end, the lower end of the special-shaped pressing plate is a special-shaped pressing surface matched with the outer diameter of the clamp ring, when the upper end of the special-shaped pressing plate is lifted, the special-shaped pressing surface at the lower end of the special-shaped pressing plate presses the outer diameter of the clamp ring, and the clamp ring is pressed and fixed by using pressing force between. The clamp ring has the advantages of low investment cost, visual and obvious effect, removal of potential safety hazards in operation, reduction of unnecessary external force damage of the clamp ring, prolongation of the service life of the clamp ring, saving of spare part purchase cost and improvement of working efficiency.
Description
Technical Field
The utility model relates to a steel industry roll assembly technical field, in particular to snap ring lifting claw of snap ring hoist and mount and dismantlement in steel industry roll assembly.
Background
Need carry out the handling installation with the snap ring and dismantle in roll assembly operation, the snap ring that need lie flat with the suspender during the snap ring installation hangs immediately, then utilize the borer to pass the snap ring locating hole, the balanced hook borer both ends of reuse suspender hang the snap ring and hang immediately the installation, still the design has the location keyway on the snap ring, need go into the snap ring keyway card on the roll key piece when the installation, nevertheless because the other terminal surface of snap ring and other installed part laminating, the snap ring tip is stretched out at hoist and mount borer both ends, the snap ring keyway can't directly buckle on the key piece, the installation process needs the manpower to take out the borer with the pinch bar is fixed with the snap ring, buckle light turn-in key piece through the pinch bar. When the clamping ring is disassembled, the clamping ring is directly screwed off from the roller through rotating the roller, and the clamping ring can be damaged under the action of gravity when being screwed off. Potential safety hazards exist in the operation process, and meanwhile, the installation efficiency is also influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a get rid of the potential safety hazard, improve work efficiency's snap ring lifting claw.
The utility model discloses a solution is such:
the clamping ring lifting claw is characterized in that at least two positioning pins extending forwards are fixedly connected to a fixing frame, and the positions of the positioning pins are matched with positioning holes in a clamping ring, so that the positioning pins can be inserted into the positioning holes in the clamping ring; the fixing frame is hinged to the middle of the special-shaped pressing plate, the upper end of the special-shaped pressing plate is a lifting end, the lower end of the special-shaped pressing plate is a special-shaped pressing surface matched with the outer diameter of the clamp ring, when the upper end of the special-shaped pressing plate is lifted, the special-shaped pressing surface at the lower end of the special-shaped pressing plate presses the outer diameter of the clamp ring, and the clamp ring is pressed and fixed by using pressing force between.
The more specific technical scheme also comprises the following steps: the special-shaped pressing surface at the lower end of the special-shaped pressing plate extends towards two sides, and the pressing surface of the special-shaped pressing plate and the clamping ring is enlarged.
Further: the length of the positioning pin is less than or equal to the hole length of the positioning hole in the clamping ring.
The utility model has the advantages that the input cost is low, and the effect is directly perceived obvious, gets rid of the operation potential safety hazard, reduces the unnecessary external damage of snap ring, extension snap ring life saves spare parts purchase cost, improves work efficiency.
Drawings
Fig. 1 is a schematic view of the usage state of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
Fig. 3 is a left side view of the structure shown in fig. 2.
The parts of the drawings are detailed as follows: the lifting device comprises a clamping ring 1, a lifting tool group 2, a fixing frame 3, a bolt 4, a nut 5, a special-shaped pressing plate 6, a lifting hole 7 and a positioning pin 8.
Detailed Description
As shown in fig. 2 and 3, the fixing frame 3 of the present invention is fixedly connected with three positioning pins 8 extending forward, and the positions of the positioning pins 8 are matched with the positioning holes on the snap ring 1, so that the positioning pins 8 can be inserted into the positioning holes on the snap ring 1; the fixing frame 3 is hinged to the middle of the special-shaped pressing plate 6 through bolts 4 and nuts 5, the bolts 4 are hinged shafts, the special-shaped pressing plate 6 is hinged into a swing rod structure, the upper end of the special-shaped pressing plate 6 is a lifting end, the lower end of the special-shaped pressing plate 6 is a special-shaped pressing surface matched with the outer diameter of the clamp ring 1, the special-shaped pressing surface at the lower end of the special-shaped pressing plate 6 extends towards two sides, the pressing surface of the special-shaped pressing plate 6 and the clamp ring 1 is enlarged, when the upper end of the special-shaped pressing plate 6 is lifted, the special-shaped pressing surface at the lower end of the special-shaped pressing.
The length of the positioning pin 8 is less than or equal to the hole length of the positioning hole in the snap ring 1.
As shown in fig. 1, when the lifting appliance is used, the positioning pin 8 is inserted into the positioning hole of the snap ring 1, the lifting appliance set 2 of the lifting appliance is connected with the snap ring 1, and at the moment, the operation of inserting the positioning pin 8 into the positioning hole of the snap ring cannot be influenced because the upper end of the special-shaped pressing plate 6 is in a free swinging state; then, the special-shaped pressing plate 6 is connected with a lifting device for lifting through a lifting hole 7 at the upper end of the special-shaped pressing plate 6, when the upper end of the special-shaped pressing plate 6 is stressed, the lower end of the special-shaped pressing plate can swing to a position where a special-shaped pressing surface presses the outer diameter of the clamp ring 1, and the clamp ring 1 is pressed and fixed by using the pressing force between the positioning pin 8 and the special-shaped pressing plate; after the lifting is in place, the lifting force born by the upper end of the special-shaped pressing plate 6 is released, so that the pressing force between the positioning pin 8 and the special-shaped pressing plate 6 can be released, and the lifting tool set 2 is taken down for next use.
