Abstract
The utility model discloses a hanging gripper for steel rails. The shape of contact part of a gripper opening and a rail is the same with the shape of a steel rail head. The upper part of the gripper opening is tightly connected with a mechanism to control the action of the wedge and the gripper opening which is composed of a U-shaped drive plate, a gripper opening spring, a tongue pin shaft, a tongue pin spring, and a tongue pin which are connected mechanically. When the steel rail is clipped, the wedge automatically fastens the steel rail in the gripper opening; when rail is unloaded, the handle is lifted upwards, and the wedge can open a lock; when the hanging gripper is lifted upwards, the rail is unloaded, and the hanging gripper for steel rails prepares to clip the gripper for the next time. Once the steel rail leaves the gripper opening, the gripper opening opens under the action of the gripper opening spring, the U-shaped driving plate pokes the tongue pin spring to a pin opening position, and wedge slides to a gripper arc under the action of a wedge spring. The utility model has the advantages of convenient work of lifting and loading, safety, and reliability.
Description
The utility model relates to a kind of tongs of using when lifting rail, and it belongs to the particularly long rail group of railway rail and hangs indispensable holding device in the operation.
At present, its pincers rail of known Lift gripper for rail, unload rail principle similar scissors, dependence waits that the deadweight that lifts rail finishes lifting operation to the gravity that the tongs jaw applies.
Existing rail is the shortest to be 12.5 meters, need operate two tongs with 2 workmans at least during lifting, and the rail that rail welding plant welds can reach 500 surplus rice, therefore, general long rail gets 20-30 position workman and operates 20-30 simultaneously tongs is carried out lifting operation.Though a commander is arranged, coordinate the lifting action, can rely on manual electric switch, 20-30 people operates 20-30 tongs is difficult to realize rail ascending velocity each point unanimity,＜cause and many tongs ccasual is in different mode of operations: the rail of pincers that has, what have unloads rail, makes that rail breaks away from jaw easily in the hoisting process, causes danger.
Particularly tens electric switches as long as there is one to break down, can both be caused danger.
The purpose of this utility model is the shortcoming that overcomes existing Lift gripper for rail, provides a kind of and in the rail hoisting process, can make the rail lifting operation not only convenient automatically with the tongs of rail fastening down in jaw of being held by pincers, and safety, reliable.
The purpose of this utility model reaches like this: a kind of Lift gripper for rail, by shell 12, suspension ring 10 constitute, its special character is to be equipped with in the shell 12 a pair of symmetrical jaw 2, is furnished with jaw axle 1 on the jaw, a pair of symmetrical tongue pin 7 is by a pair of symmetrical tongue pin spring 6, a pair of symmetrical tongue bearing pin 5, a pair of symmetrical jaw spring 4 and a pair of symmetry and the U-shaped that is close on the 2-5 of jaw top are dialled plate 3 and jaw 2 mechanical attachment, there is a voussoir 8 jaw 2 diad top, have a pair of on it and symmetrical grooves 8-1 7 mating reactions of tongue pin, handle 11 is fixed on the voussoir 8, voussoir spring 9 be pressed on voussoir 8 directly over.
Jaw 2 has jaw lower jaw 2-1, jaw maxilla 2-2, jaw wedge crack 2-3, pincers arc 2-4 and pincers top 2-5.
After tongs vised rail, it is big that the gap that jaw wedge crack 2-3 constitutes becomes, and voussoir 8 glides under the effect of voussoir spring 9, enters in the gap that jaw wedge crack 2-3 constitutes, and a pair of tongue pin 7 is dialled in pair of U-shaped under the effect of plate 3 and tongue pin spring 6 and entered latched position.At this moment have only the rail of being held by pincers to be put into ground and when mentioning handle 11 jaw 2 just can open, when slinging tongs again, rail just is removed automatically, Lift gripper for rail performs simultaneously and clamps the rail preparation next time: when rail leaves jaw 2, jaw 2 opens under the effect of jaw spring 4, U-shaped is dialled plate 3 and is stirred tongue pin spring 6 and make tongue pin 7 be in the expense position, and voussoir 8 is and waits to clamp the rail state sliding under the effect of voussoir spring 9 on the jaw pincers arc 2-4.
The process of whole lifting rail is convenient, safety, reliable.
The utility model is described in further detail below in conjunction with drawings and Examples.
Scheme drawing when Fig. 1 is the utility model pincers rail state.
Fig. 2 is the front elevation of jaw.
Fig. 3 is a Lift gripper for rail work scheme drawing.
This Lift gripper for rail has a shell 12, handle 11, suspension ring 10, the a pair of jaw 2 of being furnished with jaw axle 1 on it, a pair of symmetrical tongue pin 7 is dialled plate 3 and jaw 2 mechanical connections by tongue pin spring 6, tongue bearing pin 5, jaw spring 4 and a pair of symmetry of a pair of symmetry and the U-shaped that is close on the 2-5 of pincers top, there is a voussoir 8 jaw 2 diad top, have a pair of on it and groove 8-1 7 mating reactions of tongue pin, handle 11 is fixed on the voussoir 8, voussoir spring 9 be pressed on voussoir 8 directly over.
Jaw 2 has jaw lower jaw 2-1, jaw maxilla 2-2, jaw wedge crack 2-3, pincers arc 2-4 and pincers top 2-5, and jaw 2 is identical with the rail head shape with the rail head of rail contact portion.Lift gripper for rail is not during hanger rail, be in and wait to clamp the rail state: a pair of jaw 2 opens downwards, a pair of pincers arc 2-4 is that the center rotation is drawn close mutually with jaw axle 1, at this moment the gap minimum that constitutes of jaw wedge crack 2-3, pair of U-shaped is dialled plate 3 and stir a pair of tongue pin spring 6 under the effect of a pair of jaw spring 4, make a pair of tongue pin 7 be in the expense state, tongue pin 7 separates with voussoir 8, voussoir 8 is stepping down on the pincers arc 2-4 to lower slider under the effect of voussoir spring 9, but can not enter in the gap of a pair of jaw wedge crack 2-3 formation.
When needing hanger rail, to be in and wait that the Lift gripper for rail that clamps the rail state places on the rail head, rail head is with a pair of jaw maxilla 2-2 jack-up, a pair of jaw lower jaw 2-1 fastens rail head, it is big that jaw wedge crack 2-3 becomes, voussoir 8 is under the effect of voussoir spring 9, slip into down in the gap of a pair of jaw wedge crack 2-3 formation, jaw 2 can not open again, and rail is locked in the groove of jaw 2, and simultaneously U-shaped is dialled plate 3 and stirred tongue pin spring 6 and make a pair of tongue pin 7 close mutually, enter the position of locking voussoir 8, at this moment if upwards do not carry fixed handle 11, jaw 2 can not open automatically, and rail also just can not break away from tongs automatically.Therefore in lifting operation, rail can be not automatically-unhooked, causes danger.
In the time of need unloading rail, rail is put on the ground, in case the rail kiss the earth, the power that jaw wedge crack 2-3 clamps voussoir 8 disappears, and at this moment handle 11 can upwards be mentioned.In case handle 11 is upwards mentioned and can be driven voussoir 8 and rise to the position of being pinned by tongue pin 7, voussoir 8 is fixed on a high position, after rail is thrown off jaw 2, returns to open configuration when waiting to clamp rail at the effect lower jaw 2 of jaw spring 4.So as long as Lift gripper for rail is put into rail on the ground, mention handle, just can unload rail easily, after unloading rail, Lift gripper for rail performs again and clamps rail next time and prepare: when rail left jaw 2, jaw 2 opened under the effect of jaw spring 4, and U-shaped is dialled plate 3 and stirred tongue pin spring 6 and make tongue pin 7 be in the expense position, voussoir 8 is and waits to clamp the rail state sliding under the effect of voussoir spring 9 on the jaw pincers arc 2-4.
The process of whole lifting rail is convenient, safety, reliable.
The utlity model has obvious following advantage: in the operation of lifting rail, the Lift gripper for rail energy Clamp easily rail, behind the pincers rail, can automatically realize mechanical self-latching; To be self-locking in the jaw securely by the rail that pincers are held, and as long as rail is put on the ground, upwards mention handle, just can unload easily rail, the operation of whole lifting rail is convenient, safety, reliable.
