Description
Technical Field
The application relates to the technical field of hot processing of hook tail frames, in particular to a charging and discharging method for a hook tail frame.
Background
The coupler yoke is an important component of a coupler buffer device on a railway vehicle, and when the vehicles drag, are connected and buffer, the transmission of longitudinal force between the vehicles is directly completed, in particular, the railway vehicles are connected through the coupler, and the coupler is connected with the coupler yoke through a coupler yoke pin, so that the connection between the train vehicles is ensured, the train transportation is formed, the traction force is transmitted, and the key effect is played for the normal operation of the railway vehicles.
With the vigorous development of railway construction, the output of trains is increased, the quantity of trains put into operation is increased, correspondingly, the demand of the coupler yoke is increased, the coupler yoke is used as a main stress piece of a coupler buffer device, in the actual operation process, a locomotive is connected with a vehicle through the coupler buffer device and is pulled along a track, great force can be applied to the coupler yoke, so that stretching and bending stress is generated on each part of the coupler yoke, and as time goes by, the stretching and bending stress can lead to failure of the coupler yoke, new coupler yoke is needed for replacement, and the demand of the coupler yoke is increased gradually.
However, the existing coupler yoke has low production efficiency, and the required quantity is difficult to saturate. One of the reasons is as follows: in the existing hook tail frame production process, the high-temperature transferring efficiency of the hook tail frame is low, so that the overall heat treatment production efficiency is low. In the production link of heat treatment, a trolley furnace is often used for heating the hook tail frame, specifically, firstly, a trolley furnace door is required to be opened, the trolley body of the trolley furnace is pulled out of the trolley furnace, then the hook tail frame is orderly piled on the plane of the trolley body, after the piling is completed, the trolley body is pushed into the trolley furnace, the furnace door is closed, a corresponding control cabinet is started to control the trolley furnace to start heating, after the heating is completed, the trolley body is pulled out, and then the hook tail frame on the trolley body is gradually transferred to a quenching point or a tempering point by adopting a tool and the like. When the tool is used for transferring, steel pipes are often used as transferring tools, the steel pipes are arranged in coaxial tail pin holes of a plurality of tail frames of the same layer and the same row (column) in a penetrating mode, and then two ends of the steel pipes are lifted through travelling crane to lift the plurality of tail frames of the steel pipes. The mode is simpler to operate, but is limited by the strength of the steel pipe, a round pipe with the length of 2m can only hoist and transport 4 to 5 pieces of hook tail frames at a time, and as the steel pipe needs to be penetrated with a plurality of hook tail pin holes, the hook tail frames are required to be in a basically coaxial state when being charged, the number of the hook tail frames in a single row cannot be too large, otherwise, the subsequent transportation is inconvenient, the charging amount of the hook tail frames is greatly limited, the transportation efficiency is not high, and the overall heat treatment production efficiency is lower.
And in the specific transportation process, when the crane is transporting the hook tail frame, not only need control personnel to control the crane and remove in the crane control room, still need have operating personnel to cooperate with the crane at the platform truck stove side, the charging point side etc. to install transportation frock or command crane and transfer towing hook etc. wherein the human cost that needs to consume is higher, and overall operation efficiency is lower.

The auxiliary masonry 3 includes a plurality of rectangular refractory masonry, seven in this embodiment. And the auxiliary brickworks 3 are distributed on the table surface of the trolley furnace 2 in an equidistant strip array. The interval between two adjacent auxiliary masonry 3 is smaller than the length of the hook tail frame 1 to be transferred, and the hook tail frame 1 to be transferred is arranged on the auxiliary masonry 3. Specifically, the head and the tail of the hook tail frame 1 to be transported are respectively arranged on two adjacent auxiliary brickwork 3, namely, the hook tail frame is transversely arranged on the adjacent auxiliary brickwork 3, so that the auxiliary brickwork 3 can stably support the hook tail frame, and the hook tail frame is ensured to be stably arranged.
Step 2: and controlling the crane to hoist the tail frame fixture 4 to the position above the tail frame 1 to be transported. Specifically, the crane is controlled to hoist the tail frame fixture 4 to the piled tail frame 1 to be transported, and the tail frame fixture is positioned at the position about 20-30cm above the uppermost layer of the tail frame 1 to be transported.
The coupler yoke tooling 4 comprises a fixing frame body 41; an array of fixed rod pieces 42 are arranged on the fixed frame body 41; each set of fixing bars 42 comprises a left fixing bar and a right fixing bar symmetrically arranged on the left side and the right side of the fixing frame body 41; the top end of the fixed rod piece 42 is detachably connected with the fixed frame body 41, and the bottom end of the fixed rod piece 42 is provided with an integrally-made inward-bent hook-shaped part 43; the hook-shaped part 43 is used for placing the cross bar 44, the cross bar 44 is used for assisting in fixing the hook tail frame, and the auxiliary supporting part is the cross bar 44.
