Abstract
The utility model relates to an elastic collision prevention beam and buffering and pot supporting device which comprises a buffering part, a connecting part, a guiding part and a pot supporting part. The device is installed on the well frame of a well bore, when over hauling happens, a mine well lifting vessel collides a collision prevention beam on the well, the supporting claw of the device is pushed towards the upper-rear direction to rotate through the lifting vessel, when the lifting vessel is over the supporting claw, the supporting claw is reset under the eccentric dead weight and the effect of a tension spring, when the lifting vessel drops, the supporting claw can support the lifting vessel and buffer the lifting vessel for a certain distance, therefore, the stress condition of the well frame is improved, and the collision to the vessel and the distortion of the vessel are reduced. The device has simple structure, reliable performance, and the buffering and pot supporting effect.
Description
Technical field
The utility model relates to a kind of safety device of lifting container, especially controls a kind of elasticity collision prevention girders and buffer and supporting cage device that lifting container is crossed folding and unfolding
Background technology
The Tank-supporting device that is used at present under the collision prevention girders mostly is accepting of rigidity, the design of its holder jar power should be to promote more than five times of end load, general derrick can't satisfy its requirement of strength, though also utilize spring as buffering, but because its complex structure, can only make catching device as the shaft bottom, can't be used for the buffer and supporting cage device under the collision prevention girders.
Summary of the invention
The utility model is in order to overcome above-mentioned the deficiencies in the prior art part, a kind of elasticity collision prevention girders and the buffer and supporting cage device of preventing folding and unfolding are provided, the elasticity that this device utilizes its spring buffer and hangs steel rope absorbs the potential energy of whereabouts container, to reach the purpose of Tank support damper; Its braking force is reliable, accurate, simple in structure.
The concrete scheme that its technical matters that solves the utility model adopts is: a kind of elasticity collision prevention girders and buffer and supporting cage device, and it mainly comprises collision prevention girders 1, bearing 2, spring 5, steel rope 6, support 7, claw 9 and derrick girder steel 11 7 parts; Its bearing 2 is drum shapes, and spring 5 is housed in it, and pressing plate 3 is housed on it, and pressing plate 3 center fixation are connected with Long Circle pull bar 4, and the other end of pull bar 4 passes spring and bearing 2, and the bottom surface order is connected with steel rope 6 and support 7; Bearing 2 is fixed on the collision prevention girders; Claw 9 is fixed in support 7 and the chute 8 by bearing pin 10, and support 7 and claw 9 can slide up and down and rotate in chute 8; Chute 8 is fixed on the derrick girder steel 11 in couples; One end of extension spring 15 and the preceding bottom of claw 9 fix, and the right lower quadrant of the other end and chute 8 fixes.
Its beneficial effect is: this device is installed on the derrick, because the elastic elongation of the steel rope that has adopted spring buffer and hung absorbs the potential energy of whereabouts container, power is delivered on the collision prevention girders, improved the stress condition ， Minus of derrick little impact and the distortion of claw to lifting container, its braking force is stable, dependable performance, structure tube list is made easily, and is with low cost.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
Among the figure, 1 collision prevention girders, 2 bearings, 3 pressing plates, 4 pull bars, 5 springs, 6 steel ropes, 7 supports, 8 chutes, 9 claws, 10 bearing pins, 11 derrick girder steels, 12 back-up rings, 13 rope sheaves, 14 extension springs, 15 cages.
The specific embodiment
In the drawings, bearing 2 is a drum shape, and lower central is porose, is convenient to pull bar 4 and freely passes through, and its top is fixed with flange, and a plurality of circular holes are arranged on the limit so that with bolt be fixed in collision prevention girders 1 below; Pressing plate 3 is the disc flat board, and there is tapped bore at its center; Pull bar 4 is elongated round bars, and there is outside thread its upper end, is threaded with pressing plate 3 or welds fixingly, captives joint with an end of steel rope 6 in its lower end; Spring 5 is a plurality of disk springs, also can be cylindrical compression spring, and it is contained in bearing 2 endoporus, and pressing plate 3 removable mountings are at the upper top of spring 5, and pull bar 4 lower ends pass spring 5 and 2 times holes of bearing are connected with steel rope 6; Support 7 is by two channel bars and the assembly set that big channel-section steel is welded, its channel bar is provided with each other dorsad, two back to backs are a bit larger tham the width of claw 9, the both wings end of two channel bars is fixing with big channel-section steel both wings welding respectively, all there are upper and lower two circular holes that cooperate with bearing pin 10 bottom surface of big channel-section steel both wings and two channel bars, there is an elongated slot bottom surface of big channel-section steel, is convenient to claw 9 and rotates therein.Chute 8 is rectangular module that are welded as by channel-section steel both wings and steel plate, have on channel-section steel two aerofoils just and bearing pin 10, support 7 and claw 9 slotted hole that slides of easy on and off therein, have on the bottom surface of channel-section steel and the steel plate and be convenient to the elongated slot that claw 9 rotates, be convenient to claw 9 and rotate therein; Be convenient to bearing pin 10 together with support 7 and claw 9 easy on and off slip therein, have on the bottom surface of channel-section steel and the steel plate and be convenient to the elongated slot that claw rotates, groove width is a bit larger tham claw 9 wide and thickness; Claw 9 is subtriangular obform bodies, two base angle is circular arc and circular hole is arranged and the circular arc slotted hole, there is concave arc on base (rear portion), make forward off-centre of claw center of gravity, bearing pin 10 is arranged in the hole, and it is fixing with back-up ring 12, it is fixed on the support 7, claw one bottom bearing pin is a fulcrum, long arc-shaped holes with its top is a path of motion, and camber line rotates before and after doing around upper pin, when long watt of claw top arc goes to leftmost position, the plane is horizontal on the claw 9, and the contact surface with lifting container above claw 9 left ends (front end) is the plane.Chute 8 is fixed on the girder steel 11 of derrick, use in pairs, claw 9 is fixing with support 7 and chute 8 by bearing pin 10 and back-up ring 12, support 7 and claw 9 can slide up and down in chute, the lower end of steel rope 6 is connected with rope sheave on being fixed on support 7, rope sheave 13 is positioned at place in the middle of support 7 tops, welds mutually with channel bar two bottom surfaces in the support 7.One end of extension spring 14 and the preceding bottom of claw 9 fix, and the right lower quadrant of the other end and chute 8 fixes.
