Abstract

The invention relates to a lifting and transport equipment, in particular, to gripping devices for transporting long loads. The aim of the invention is to improve the reliability and expansion of the range of lifted goods. The gripping and holding of the load 12 in the catch legs 5 takes place with the help of two double-arm levers 10 installed in the lower part of the traverse 1. The vertical movement of the gripping legs 5 relative to the traverse 1 to grip and release the cargo is carried out under the action of the weight of the load 12 by means of rollers 4 mounted on arms 8, located in the upper part of the crosspiece 1. Rollers 4 interact alternately with conical 3 and cylindrical 7 working surfaces of the guides 2 connected to the upper part of the lifting legs 5. 3 Il.

The invention relates to lifting and handling equipment, in particular to gripping devices for the transport of long loads.

The purpose of the invention is to increase the reliability of bjocTH and the expansion of the range of lifted goods.

FIG. 1 shows a gripping device; in fig. 2 shows section A-A in FIG. 1 (device at the seizure of cargo); t | a of fig. 3 - the same device when lifting cargo.

The gripping device contains g traver- cjy 1, guides 2 fixed on it by a working surface in the form of a truncated

For transportation of cargo 12, an earring 18 is hung on the hook of the load-lifting mechanism, the pick-up legs 5 are brought under the basis of the load 12, lying, it is on supports 17. When

with the lifting of the weight under the action of its weight, the lifting paws 5 are lowered with respect to the traverse 1, the guides 2 are conical working surface 3 unclenches the springs 6, the single-arm levers 8 move apart relative to the axes 19 of their rotation, and the rollers 4

0 transitions to the cylindrical 7 working surface of the guides 2. The two shoulders hold down the levers 10 by means of t g 13, which by one ends 14 are pivotally connected to the second arms 15 of the clamping levers 3, installed with the possibility of 15 O- with the second ends 16 pivotally

connected to the crosspiece 1, the load clamp 12 is rotated and carried out.

The vertical movement relative to the crosspiece 1 by means of rollers 4, interacting with the working surface of the guides 2 gripping bodies 5 and horizontally positioned springs 6. The horizontal 2 are made with a vertical 1 | 1 or 7 working surface, placed over the conical 3 and with her on the part of a greater foundation, and. The gripping organs 5 are made in the form of an под-shaped pick-up paws, the upper parts 25 which are connected to the guides 2 from the lower side of the smaller truncated body 3. The device is fitted with 1–1 and 1 in the upper part of the traverse 1 with the possibility of turning in its longitudinal plane

connected to the crosspiece 1, the load clamp 12 is rotated and carried out.

The release of the load 12 when installed on the supports 17 occurs in the following sequence: the yoke 1 continues to descend with respect to the load 12, the pushing bars 14 press the shoulders 15 of the clamping levers 10, move the lifting feet 5 relative to the yoke 1, the levers 10 rotate and release the load.

Invention Formula A gripping device containing a traverse that guides, with a working surface in the form of a truncated cone, an mouth (shoulder-arms with levers 8 to accommodate a vertical with the possibility of 4 on the ends of the arms 9 of the arms, the cones 1 | 1y of the springs 6 are fixed on the arms 9 of the levers IOB 8 under the rollers 4. The device is also Equipped with at least one L-2 rotatable two shoulders installed at the bottom of the tpaBepcbi 1 shaped gripping body and horizontally positioned springs, characterized in that, in order to increase reliability and The levers 10 for engaging 35 extending the nomenclature of the lifted loads ((with the shoulders 11 from the lifted loads, the guide is made with a cylindrical 12, rigid rods 13, the first ends of the 14 vertical section, which are pivotally connected to the second Kamv (15 clamping levers 10, and the second large base, the gripping body is upper). The ends 16 are hingedly connected to the front part of the body and rigidly connected to direction 1. 1. The transported load 12 is loaded from the side its smaller base, which It is new on supports 17, and traverse 1 is connected to the joint part, and the device is fitted with an earring 18 for hanging on the hooks in the upper part of the traverse with a lifting mechanism. The possibility of rotation in its longitudinal device operates as follows. pru- In the initial position, when the gripper45 with single-arm levers, on which the device is free of load 12, is directed, rollers are placed under the springs, the mounting 2 are supported by a conical 3 working parts, and the traverse is turned in the lower part NOSTA on rollers 4 rychagovrotnymi one-armed double-arm lever 8 for pressing associated springs 6 and uderzhivayutgruza and rigid connecting rods; the ends of which the grasping paws 5 from moving downwards are hinged one with the second shoulders — relative to the crossbeam 1. Two shoulders with two double shoulders, and the others with the heavy levers 10 as open as possible. For transportation of cargo 12, an earring 18 is hung on the hook of the load-lifting mechanism, the pick-up legs 5 are brought under the basis of the load 12, lying, it is on supports 17. When lifting the weight under the action of its weight, the gripping paws 5 are lowered with respect to traverse 1, the guides 2 by the conical working surface 3 expand the springs 6, the single-arm levers 8 move apart relative to the axes 19 of their rotation, and the rollers 4 transition t to the cylindrical 7 working surface of the guides 2. Two shoulders clamping levers 10 with the help of t g 13, which by one ends 14 are hingedly connected with second shoulders 15 clamping levers O- with second ends 16 of hinges   О- with second ends 16 pivotally connected to the crosspiece 1, the load clamp 12 is rotated and carried out. The release of the load 12 when installed on the supports 17 occurs in the following sequence: the yoke 1 continues to descend with respect to the load 12, the pushing bars 14 press the shoulders 15 of the clamping levers 10, move the lifting feet 5 relative to the yoke 1, the levers 10 rotate and release the load. Invention Formula A gripping device comprising a traverse, a guide with a frustoconical working surface, installed with the possibility of vertical movement relative to the crossbeam by means of rollers, at least one L-shaped gripping body and horizontally positioned springs, characterized in that, in order to increase reliability and /// U ////////////////////////////////////.
