Description
Technical Field
The invention relates to the technical field of push rod furnace mechanical equipment, in particular to a bidirectional push-pull trolley for a push rod furnace.
Background
The push rod furnace is used for pushing the material trays placed on the track into the furnace or out of the furnace periodically by means of the bidirectional push-pull vehicle so as to realize the heat treatment process of the workpieces placed on the material trays. The push rod furnace has strong adaptability to different heat treatment processes, so that the push rod furnace is convenient for forming a production line and is widely applied to heat treatment processes of quenching, normalizing, annealing, tempering, carburizing, nitriding, carbonitriding and the like.
Referring to fig. 1, a bidirectional push-pull cart for a push rod furnace in the prior art is shown, which comprises a frame 10, a left unidirectional handle 20a, a right unidirectional handle 20b, a left push sprocket 30a, a right push sprocket 30b, a push-pull chain 40, a left push-pull hook 50a and a right push-pull hook 50 b. A walking bridge 11 is arranged on the upper portion of the frame 10 along the horizontal direction, a push-pull chain track 12 is arranged below the walking bridge 11 of the frame 10, and two ends of the push-pull chain track 12 correspond to two ends of the walking bridge 11 to form a push-pull chain circulating walking loop. The left one-way handle 20a and the right one-way handle 20b are hinged to the left end and the right end of the walking bridge 11 on the frame 10 respectively, and when the left one-way handle 20a or the right one-way handle 20b naturally falls down due to the gravity of the left one-way handle 20a or the right one-way handle 20b to be in a horizontal position, the left one-way handle 20a or the right one-way handle 20b is connected with the left end or the right end of the walking bridge 11 to cut off a push-pull chain circulation walking. The left propelling sprocket 30a and the right propelling sprocket 30b are respectively and axially arranged on the frame 10 and are respectively positioned below the left end and the right end of the walking bridge 11. The push-pull chain 40 is engaged with the left push-pull chain wheel 30a and the right push-pull chain wheel 30b and is driven by the left push-pull chain wheel 30a and the right push-pull chain wheel 30b to travel along a push-pull chain circulation travel loop. The left push-pull hook 50a and the right push-pull hook 50b are respectively arranged at the left end and the right end of the push-pull chain 40 and move along with the push-pull chain.
When pushing materials to the right side, the left pushing chain wheel 30a and the right pushing chain wheel 30b are driven by the speed reducer to rotate clockwise to drive the pushing zipper 40 to walk rightwards, at the moment, the left one-way handle 20a is jacked up by the pushing and pulling chain 40, the right one-way handle 20b naturally falls down by gravity to be in a horizontal position and is connected with the right end of the walking bridge 11, a circulating walking loop of the pushing and pulling chain is cut off, and the pushing zipper 40 drives the left pushing and pulling hook 50a to push the material tray 60 on the rack 10 to move rightwards while walking rightwards along the walking bridge 11; when the tray 60 is in place, the left pushing chain wheel 30a and the right pushing chain wheel 30b are driven by the speed reducer to rotate anticlockwise, and the pushing chain 40 is driven to walk leftwards along the walking bridge 11 to return to the original position.
When the material tray is pushed to the left side, the left pushing chain wheel 30a and the right pushing chain wheel 30b are driven by the speed reducer to rotate anticlockwise to drive the pushing zipper 40 to walk leftwards, the left pushing and pulling hook head 50a moves leftwards along the pushing zipper 40, when the left pushing and pulling hook head moves downwards along the pushing and pulling chain track 12 through the left one-way handle 20a, the left one-way handle 20a naturally falls to be in a horizontal position under the action of gravity and is connected with the left end of the walking bridge 11, a pushing zipper circulating walking loop is cut off, meanwhile, the right pushing and pulling hook head 50b moves upwards from the right side along the pushing and pulling chain track 12 to jack the right one-way handle 20b, and therefore the right pushing and pulling hook head 50b pushes the material tray 60; when the tray 60 is in place, the left pushing chain wheel 30a and the right pushing chain wheel 30b are driven by the speed reducer to rotate clockwise, and the pushing chain 40 is driven to walk rightwards along the walking bridge 11 to return to the original position.
However, in practical applications, the bidirectional push-pull cart is completely exposed, dust and impurities can be accumulated on the left one-way handle 20a and the right one-way handle 20b, and oxide skin of a processing workpiece, which is dropped during the movement of the tray 60, can cause that the left one-way handle 20a and the right one-way handle 20b can not naturally fall down to form a bridge due to self weight, and can keep a tilted state, and when the left push-pull hook 50a and the right push-pull hook 50b pass through the left one-way handle 20a and the right one-way handle 20b, the left one-way handle 20a and the right one-way handle 20b can not be guided, and can be impacted, so that the bidirectional push-pull cart can not normally operate.
