Abstract
The utility model discloses a self -discharging railway carriage stone tongs, including the davit hang oneself from a beam, set up the davit in the middle of hanging oneself from a beam rings and set up at the hang oneself from a beam davit at both ends of davit, the davit rotate connect on the davit is hung oneself from a beam and/or with the davit sliding connection on the horizontal direction that hangs oneself from a beam, the davit inwards is equipped with and hangs the elbow angle, hang the elbow angle and outwards rotate the connection arm lock through the arm lock mount pad, be the clamping position of tipper railway carriage one side between the clamping jaw of arm lock and the clamping jaw of davit. The utility model discloses can be used for lifting by crane the tipper railway carriage, dull and stereotyped railway carriage, storehouse bars railway carriage, the operation is thus simple, it is convenient, steady safety during the crane case, can avoid vibration and maloperation to cause the open potential safety hazard of davit effectively, and guaranteed just to be in the auto -lock state before hoist and mount, avoided hoisting the back because rocking of lifting rope arouses that the claw hook opens, the not hard up messenger even of hoist and mount is hung the potential safety hazard that the piece drops, furthermore, hang oneself from a beam the slider of both sides and can satisfy the hoist and mount in different model carriages through removing the davit.
Description
Technical field
This utility model belongs to and relates to a kind of hanging device, is specifically related to a kind of dumper skip stone tongs.
In the assembling process of dumper, big parts have been generally designed hoisting ring or hole for hoist, but case body of self-discharging vehicle is excessive, workman is in hoisting process, and angle and control point are difficult to grasp, and often cannot link up with, or that hangs is insecure, often occurring that unhook landing even scratches the phenomenon of product, therefore cause lifting efficiency low, operation behaviour is lack of standardization and there is bigger potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, esy to use, safe and reliable, and is greatly improved the stone tongs of lifting efficiency.
Technical solutions of the utility model:
A kind of dumper skip stone tongs, including arm overarm, it is arranged on the suspension ring in the middle of arm overarm and is arranged on the arm at arm overarm two ends, arm is rotatably connected on arm overarm and above and/or is slidably connected in the horizontal direction with arm overarm, described arm is provided inwardly with arm bent angle, described arm bent angle is turned out connecting jig arm through jig arm mounting seat, is the clamping position of tipper carriage side between jaw and the jaw of arm of jig arm.
The bottom of described arm is L-shaped structure, the upper end of arm and arm hinged formation the first pin joint of overarm, the arm bent angle of arm and jig arm mounting seat hinged formation the second pin joint.
The both sides of described arm overarm are equipped with chute, and both sides chute is connected with slide block, the upper end of arm and slide block hinged formation the first pin joint.
Described jig arm is arranged with two clamping limbs relative to arm, and two clamping limbs are equipped with inside jaw, forms 3 clampings between jaw and the jaw of arm of two clamping limbs.
Being provided with lacing wire between the both sides of described suspension ring and arm overarm, lacing wire forms gusseted with the side of suspension ring and the upper surface of arm overarm.
This utility model can be used to hoisting dumper railway carriage, flat board railway carriage, storehouse grid railway carriage, simple to operate, convenient, steady safety during crane case, only jig arm or arm need to be opened during lifting, when lifting, the deadweight due to jig arm can be close from trend arm, two of jig arm form 3 clampings between jaw and the jaw of arm, the potential safety hazard that vibration causes arm to open with maloperation can be effectively prevented from by this self-locking structure, and ensure that before lifting, be at self-locking state, avoid after slinging owing to rocking of lifting rope causes claw hook to open, lifting loosens the potential safety hazard even making to be come off by hanging piece, in addition, the lifting in different model compartment can be met by the slide block of mobile arm overarm both sides.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment 1 structural representation.
In figure: arm overarm 1, suspension ring 2, lacing wire 3, the first pin joint 4, jig arm mounting seat 5, jig arm 6, arm 7, the second pin joint 8, slide block 9.
Detailed description of the invention
Embodiment 1: as shown in Figure 1.
A kind of dumper skip stone tongs, including arm overarm 1, it is arranged on the suspension ring 2 in the middle of arm overarm 1 and is arranged on arm and hangs oneself from a beam the arm 7 at 1 two ends, arm 7 is rotatably connected in arm overarm 1 and/or is slidably connected in the horizontal direction with arm overarm 1, described arm 7 is provided inwardly with arm bent angle, described arm bent angle is turned out connecting jig arm 6 through jig arm mounting seat 5, is the clamping position of tipper carriage side between jaw and the jaw of arm 7 of jig arm 6.
The bottom of described arm 7 is L-shaped structure, and the upper end of arm 7 and arm are hung oneself from a beam 1 hinged formation the first pin joint 4, the arm bent angle of arm 7 and jig arm mounting seat 5 hinged formation the second pin joint 8.
Described jig arm 6 is arranged with two clamping limbs relative to arm 7, and two clamping limbs are equipped with inside jaw, forms 3 clampings between jaw and the jaw of arm 7 of two clamping limbs.
Being provided with lacing wire 3 between the both sides of described suspension ring 2 and arm overarm 1, lacing wire 3 forms gusseted with the side of suspension ring 2 and the upper surface of arm overarm 1.
Embodiment 2；The both sides of described arm overarm 1 are equipped with chute, and both sides chute is connected with slide block 9, the upper end of arm 7 and slide block 9 hinged formation the first pin joint 4, can be met the lifting in different model compartment by mobile slide block 9.
This utility model can be used to hoisting dumper railway carriage, flat board railway carriage, storehouse grid railway carriage, simple to operate, convenient, steady safety during crane case, only jig arm 6 or arm 7 need to be opened during lifting, when lifting, the deadweight due to jig arm 6 can be close from trend arm 7, 3 clampings are formed between two jaws and the jaw of arm 7 of jig arm 6, the potential safety hazard that vibration causes arm to open with maloperation can be effectively prevented from by this self-locking structure, and ensure that before lifting, be at self-locking state, avoid after slinging owing to rocking of lifting rope causes claw hook to open, lifting loosens the potential safety hazard even making to be come off by hanging piece.
