Description

The invention relates to heat treatment of metals and alloys and can be used in units for thermal and chemical-thermal treatment of products for mechanization of loading and unloading operations.

A device for loading and unloading pallets is known, including a gripping mechanism and a mechanism for pushing JQ pallets, the actuators of which are fixed on a drive plate chain moving in a guide fixed along the entire route of the pallets, including a g nofl quenching tank and in a chamber furnace (ed. St. R EDOBZ1).

However, the known device is complex in design. twenty

A device for loading pallets is known, comprising a frame with a guide mounted in it with a swing carriage with swinging grips and stops for changing the position of the gripper 25 relative to the pallet (autoswitch K1 9 43511).

Only one known device does not provide for the unloading of pallets from the oven and subsequent loading into the order (30 loko tank.

The purpose of the invention is the expansion of technological capabilities

This goal is achieved by the fact that in the device for loading pallets 35, containing a frame with rails, a drive carriage with a swinging grip installed therein and stops to change the position of the grip relative to the level of the pallet, the rails are fixed to the side of the pallet track , the drive carriage is provided with a laterally fixed rod on which the two-arm lever is pivotally mounted, the larger arm of which has a hook and a pushing surface, and the minor arm has a finger for engaging with the groove of the rigidly fixed and on the frame of the end stop, the contact surface for interacting with the adjusting screw fixed on the rod and the contact surface for interacting with the horizontal surface of the support flag pivotally mounted on the rod, while the end control is rigidly fixed on the frame for turning the support flag 5 and the intermediate is pivotally fixed emphasis unilateral action.

In FIG. 1 shows the proposed device, a General view; in FIG. 2 is a view along arrow A in FIG. 1; in FIG. 3 node I in FIG. 1; in FIG. k is a view along arrow B in FIG. 2; in FIG. 5 is a view along arrow B on the League. 1.

The device for loading pallets comprises a frame 1 with a roller track for the pallet and guides 2 attached to it from the side and a drive carriage 3 with a transverse rod mounted on them, on which the two-arm lever 5 is pivotally mounted and the Checkmark 6 is supported on the vertical axis and the plate 7 is rigidly fixed with adjusting screw 8 The larger shoulder 9 of the lever 5 has a pushing surface 10 and a hook 11. The smaller shoulder 12 of the lever 5 has a finger 13, a contact surface 1 for interacting with the horizontal surface 15 of the supporting flag 6 and a contact surface 16 for engagement with the adjusting screw 8. On the frame 1 prior to the pallet roller track rigidly fixed abutment with the open end inclined groove 17 for engagement with paltsem- 13 and the abutment 18 for the support return check boxes 6 to its original position. In addition, on the frame 1, a single-acting intermediate intermediate 19 is pivotally fixed to withdraw the supporting flag 6 from

working position. i

The device provides loading and unloading of the chamber furnace and quenching tank with a lifting table with pallets with products supplied to the thermal section by overhead transport.

The device operates as follows.

The pallet with the products of the upper transport is installed on the roller track and the carriage drive 3 is turned on. When the carriage 3 moves to the right to load, the finger 13 interacts with pause 17 and the two-arm lever 5 is turned clockwise until the surface C of the smaller arm 12 and the horizontal surface 15 of the supporting flag 6. The surface 10 abuts against the end of the pallet. The pan then moves into the oven. The emphasis 19 is rejected and skips the supporting flag 6, not rejecting it. Since when opo

If the lever 3 on the supporting current 6 hook 1 1 is above the level of the pan, then when the carriage 3 moves backward, the pallet remains in the furnace. However, when the stop 19 passes, the supporting flag 6 rotates and its surface 15 is brought out of contact with the surface And the lever. In this case, the lever 5 rotates clockwise until the surface 16 stops against the adjusting pint 8 and takes half position, at which the pallet can hook the hook 11. After this, the carriage 3 is stopped in the intermediate position.

At the end of the heat treatment, the carriage 3 is again moved to the furnace side. The inclined rear side of the hook 11 interacts with the edge of the pallet, the lever 5 rotates counterclockwise and the hook 11 under the influence of its own weight engages with the edge of the pallet.

During the reverse stroke of the carriage 3, the pallet is moved to the lifting table of the quenching tank and the carriage 3 drive is switched off. The pallet on the table is lowered into the tank. After hardening of products, it is raised to the previous level. In this case, the edge of the pallet again engages with the hook 11 remaining in its former position. Then, the carriage drive 3 is turned on again and the pallet is moved to the range of the upper transport. In this case, the finger 13 enters into the groove 17 and the lever 5 rotates counterclockwise, disengages from the pallet and leaves the coverage area of the upper transport. At the same time, the supporting flag Ј interacts with
