Abstract
The utility model discloses a special hoisting clamp for a sector eccentric block, which comprises a clamp jaw and an adjusting device and is characterized in that an angle between an attaching surface and a wedge surface of the clamp jaw is an acute angle; and the clamp jaw is connected with the adjusting device for adjusting the relative distance of the clamp jaw. By adopting the special hoisting clamp for a sector eccentric block, an adaptive floating adjustment function can be realized for the whole shape of a sector workpiece or component, the stress is balanced as much as possible between a clamping surface of the clamped clamp jaw and a contact surface of the workpiece in a hoisting process, the hoisting operation and quality of the hoisted sector workpiece are guaranteed, the hoisting efficiency and the construction safety of people are effectively improved, and the hoisting or mounting construction of the sector workpiece can be performed preferentially.
Description
Technical field
The utility model is applicable to metallurgical equipment, specifically, relates to a kind of anchor clamps that are exclusively used in fan-shaped workpiece or parts lifting.
Background technology
To the lifting of the fan-shaped workpiece of big weight or parts, it is the constructing operation that regular meeting runs in industry or the engineering.Be example with the vibration excitor eccentric block, it is 90
0Sector structure, in construction, can not tie and to prize, thereby need to adopt special-purpose stone tongs to construct, at present the hanging method that adopts is to tie up with steel cable (also can with two side by side) at the arc surface of eccentric block that the back is vertical to lift, because both lateral sides is the axial attachment face of mounting hole, so can not have other anchor clamps or steel rope to contact with attachment face.At present there is very big hidden danger in this hanging method that adopts in safety, and having slightly has some setbacks just the possibility that comes off because tie up difficulty, need with radial alignment and the pretension steel rope of eccentric block.
Fan-shaped eccentric block is the eccentric oscillatory system of a non-regular shape, is characterized in order to reach eccentric purpose, and self out-of-shape, deal is heavy, is in vacant state during installation, so the difficulty relatively of the installation in the lifting process.
Summary of the invention
At above-mentioned situation, the utility model will provide a kind of lifting construction anchor clamps that improve structure, can reach the fan-shaped workpiece of clamping or the global shape of parts and have adaptive floating type adjustment function, the contact surface that reaches the clamping face that makes the clamping catching and workpiece stressed balanced as far as possible in hoisting process, be conducive to guarantee to be lifted lifting operation and the quality of fan-shaped workpiece, actv. improves lifting efficient and personnel's construction safety, can have precedence over lifting or the installation of fan-shaped workpiece.
For addressing the above problem, the technical scheme that the utility model adopts is:
Adopt the special-purpose sling and jig of a kind of fan-shaped eccentric block, comprise catching 6, it is characterized in that: described catching 6 is provided with the control apparatus of regulating catching relative distance, and the binding face of catching 6 and the angle between the wedge surface are less than 90 ° angle.The anchor clamps top is provided with a suspension hook 10.
Described control apparatus comprises screw rod 1, and jam nut 2 supports weighing lever a3, connecting rod a4, hinge 5, catching 6, connecting rod b7, nut 8 supports weighing lever b9, suspension hook 10, screw rod 1 connection is supported weighing lever a3 and is supported weighing lever b9, and screw rod 1 has jam nut 2 with support to weighing lever a3 junction, supports weighing lever a3 is connected with catching 6 with hinge 5 by connecting rod a4, support is connected with catching 6 by connecting rod b7 weighing lever b9, and screw rod 1 is threaded by nut 8 to weighing lever b9 with support.
Described control apparatus also can be and comprises catching 6, and suspension hook 10 is regulated screw mandrel 11, and described control apparatus is for passing through to regulate screw mandrel 11, the relative distance of regulating catching 6.
Beneficial effect:
Owing to adopted technique scheme, compared with prior art, the utility model can make the global shape of fan-shaped workpiece or parts that adaptive floating type adjustment function is arranged, reach the stressed as far as possible equilibrium of contact surface in hoisting process of clamping face and the workpiece of the catching that makes clamping, be conducive to guarantee to be lifted lifting operation and the quality of fan-shaped workpiece, actv. improves lifting efficient and personnel's construction safety, can be of value to lifting or the installation of fan-shaped workpiece.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
Among the figure: the 1-screw rod; The 2-jam nut; 3-supports weighing lever a; 4-connecting rod a; The 5-hinge; The 6-catching; 7-connecting rod b; The 8-nut; 9-supports weighing lever b; The 10-suspension hook; 11-regulates screw mandrel.
The specific embodiment
Embodiment 1:
As shown in Figure 1, the special-purpose sling and jig of a kind of fan-shaped eccentric block, comprise catching, control apparatus, anchor clamps two catchings 6 binding faces are held on circular arc two avris of fan-shaped eccentric block respectively, and along supporting the weighing lever rotation, two catchings become to shrink the pretension state by screw rod 1 anticlockwise direction, to become upper thread to contact stressed with the arc surface of fan-shaped eccentric block thereupon for catching 6 wedge surfaces, becomes clamped condition.After confirming that clamping is errorless, in order to prevent screw rod 1 and to support relative the getting loose between the weighing lever a, with jam nut 2 lockings, to play the effect of the insurance that gets loose.
As shown in Figure 1, screw rod 1 is the dextrorotation formula, and the screw rod clockwise direction is along supporting weighing lever 1 rotation, support is to weighing lever a and support the change of the relative distance between the weighing lever b big, under the effect of connecting rod mechanism, the relative distance between two catchings 6 also increases thereupon, and be the anchor clamps relaxation state this moment.Otherwise dwindle, be clamping direction.
Embodiment 2:
As shown in Figure 2, control distance between two catchings by the adjusting of regulating screw mandrel, to clamp sector.
The utility model is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection domain of the present utility model.
