Abstract

FIELD OF THE INVENTION The invention relates to a lifting and transport equipment, namely to lifting devices. The aim of the invention is to simplify the design of the device. The gripping device for rail links comprises a traverse 1 with tick-borne gripping bodies fixed at its ends, the central axis 10 of which is placed in a shaped groove 2 made in the traverse. An axle 4 and a spring are located on the axis, the other end is connected to the crossmember 1. When the anvil 4 interacts with the rail head, the central axis 10 is successively moved in the shaped slot 2, which ensures automatic gripping and releasing of the rail links along the established cycle with a simple structural design of the device.

FIELD OF THE INVENTION The invention relates to lifting and transport engineering, namely, to load handling devices.

The purpose of the invention is to simplify the design of the device.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - tick-borne grip at the moment of lowering the load; in fig. 4 - the same at the time of seizure of cargo.

The gripping device for rail links includes a yoke 1, at each end of which figured grooves 2 are made, located in its walls, a clamp-type gripping body 3, an emphasis 4 with an elongated base 10

The action of the springs 8, working in this case for stretching, and the weight of the tong clamp 3 moves in the shaped grooves 2 up to the stop in the notches 12 of the fixing plates 11. In this case, the tongue clamp 3 is open, and its central axis 10 is fixed. When the traverse is next lowered onto the rail link, the stop 4 interacts with the rail head and moves upward the central axis 10 in the shaped grooves 2 until the traverse 1 lies on the elongated base 5 of the stop 4. And simultaneously with the vertical movement, the central axis 10 moves and horizontal plane to the right due to the force of the rod 5 and the locking mechanism of the 15 8 position (in this case, they operate on

stretching). At the same time, the tick-borne gripping body 3 is maximally opened, and its central axis 10, coming out of the notches 12, plastic 11, is fixed.

When the load-lifting device is turned on, the lifting of the rail link of the yoke 1 rises up, thus releasing the elongated base 5 of the stop 4 and, as a consequence, the central axis 10, which under the action of the springs 8 and the weight of the clamping body 3 moves in the figure grooves 2 until the levers of the tick-borne gripping body 3 do not girth and the rail head (Fig. 4). After that, the gripped rail link is moved to the place of installation.

The invention provides automatic gripping and release of rail links with a simple structural design of the device.

gripping body. Tick-borne gripping body 3 is hingedly attached to traverse 1 by means of axis 6, tg 7 and springs 8, and a groove 9 is made in one of the levers of the tong-borne gripping body 3. Each spring 8 is pivotally attached to the body 1 at one end and the other axis to the central axis 10 fixed on the clamped grip organ 3. The central axis 10 is hingedly connected to the stop 4. The fixing mechanism of the clamp clamp 3 includes fixing elements made in the form of a pair of plates AND with recesses 12 for accommodating the central axis 10. Each-11 s notch rigidly fixed on traverse 1 and located at the level of grooves 2. The side surface of each plate And forms with groove 2 a trajectory for cyclic movement of the central axis along it and 10 with the help of springs 8 and an emphasis 4.

The device works as follows.

When installing the gripped rail link, the stop 4 with the elongated base 5 touches the rail head and moves upward the central axis 10 of the tong clamp 3 in the shaped grooves 2 and recesses 12 until then.

Claims (1)

Invention Formula The gripping device for rail links, containing a carrier traverse with grooves made at its ends, tick-borne grippers at its ends of traverse 1, does not lie on the elongated main organs with an etching 5 of the stop 4 placed in the grooves. Simultaneously with the vertical movement, the central axis 10 moves in the horizontal plane due to the force of the springs 8, which in the lower position of the central axis 10 operate on the versions are perpendicular to its plane by the central axes, each of which has an emphasis for interacting with the rail head, and a mechanism for fixing the position of the clamping gripping bodies, including compression, i.e., the central axis 45 is moved parallel to its traverse 10 left. As the central axis 10 is moved by the support 4 upward in the shaped grooves, the length of the springs increases and they begin to work on stretching (i.e., they move the central axis 10 to the right). In this plane, at the level of the grooves, a pair of plates and a spring, in order to simplify the construction, each plate is rigidly connected to the crosshead and is shaped as a notch in its upper part, and In the position of the tick-borne gripping organ 3 max-50, each groove of the traverse is figured with a protruding opening (Fig. 3). When powering up this, each central axis is mounted with the possibility of its contact with the external contour of the plates, and each spring is attached at one end to the central axis, and the other to the traverse below the plates. for lifting the rail link, the yoke 1 rises up, freeing the elongated base 5 of the stop 4 and as a consequence the central axis 10, which under the action The action of the springs 8, working in this case for stretching, and the weight of the tong clamp 3 moves in the shaped grooves 2 up to the stop in the notches 12 of the fixing plates 11. In this case, the tongue clamp 3 is open, and its central axis 10 is fixed. When the traverse is next lowered onto the rail link, the stop 4 interacts with the rail head and moves upward the central axis 10 in the shaped grooves 2 until the traverse 1 lies on the elongated base 5 of the stop 4. And simultaneously with the vertical movement, the central axis 10 moves and horizontal plane to the right due to the force of the spring 8 (in this case, they work on 35 Invention Formula The gripping device for rail links, containing a carrier traverse with grooves made at its ends, clamp-shaped gripping bodies located at its ends with traverse trenches perpendicular to its plane, the central axes, each of which has an emphasis for interacting with the rail head, and a locking mechanism the position of the tick-borne gripping bodies, including a plane at the level of the grooves, a pair of plates and a spring, characterized in that, in order to simplify the construction, each plate is rigidly connected to the crosspiece and is made figured with a notch in its upper part, and each groove of the traverse is shaped with a protrusion corresponding to the recess of the plates, with And yap n and. about ftsa.1 BUT at
