Lock for the hoods of a coil transport trolley

The invention relates to a lock for the hoods of a Coiltransportwagens5 whose loading space through the fixed " th end walls and several, preferably three telescopic telescopic hoods is limited, the hoods near their lower ends support rollers and with these rollers on running rails on the side of the underframe of the coil transport trolley sit up »

Coil transport car hoods, which can be telescoped into one another, are usually attached by latches or pawls locked to the end walls of the coil transport trolley »Due to the telescopic design of the hoods, there are on the end walls outer hoods also locked the inner hoods by 'bracing Their stal side sealing profiles are secured against longitudinal displacement »To avoid the Transferring inertial forces of the hoods to the end walls via their locking means that the hoods are locked on both sides Longitudinal sides of the car required With the known locks, the lock must be used to open or close the hoods can be operated from both sides of the car · .. This arrangement is complex to operate and involves dangers for the operating personnel in itself

The hoods are pushed into one another to load and unload the car. It is conceivable that the coil transport trolley for loading or unloading with a 3-part hood roof, for example is opened to a third from an end wall insufficient fixing of the hoods in this open position.

The object of the invention is now to provide a lock

for the hoods of a coil transport car of the type mentioned to find the operation of the locking of both Long sides of the wagon iron on a long side of the wagon allows the hoods in the open position to prevent unintentional closing secures and the other the disadvantages of those described at the beginning Execution avoids "

This object is achieved according to the invention in that at the bottom of the front ends of the outer hoods locking cams and vertically above each Sperrnoekens one by one horizontal, two-armed pivoting axis running in the transverse direction of the car, towering over the sperm docks on both sides Release lever is arranged, which rotatably with an outside before the hood arranged operating lever is connected, and that on the underframe of the coil transport carriage near its longitudinal end or -near-the -long sendea and near-the-ends of the-middle Hoods are arranged vertically pivotable, spring-loaded and the sliding path of the Spermocken locking pawls. The locking pawls, which are arranged symmetrically to the longitudinal axis of the car, are guided by one in the underframe of the car Shaft connected to one another in a rotationally fixed manner. The pawls on the car ends expediently have run-up bevels for the Spermocken in the closing direction of the hoods, while the middle pawls run-up bevels for the Spermocken 'in Have the opening direction of the hoods. Furthermore, the pawls have starting bevels for the pivoted in the end position Release lever in both directions. With the invention, the hoods are automatically locked in the end position. By If the actuating lever is pivoted in the direction of displacement, the pawls are disengaged and the hoods are moved. When the hoods are moved in the opening direction, the locking cams snap behind the hood when the hood is open central pawls. The hoods are thus secured against unintentional displacement in the closing direction. By the connection of the pawls with one another can lock the two longitudinal sides of the car from one longitudinal side of the car to be triggered. Due to the construction according to the

the invention is thus a substantial simplification of the Actuation and a reduction in the sources of danger "causes."

Details of the invention are based on an exemplary embodiment explained.

FIG. 3 shows a section along line III-III in FIG. 2

The loading space of the coil transport wagon is created by the underframe 1, the end walls 2 and the hoods 3? 4 and 5 limited. Each hood 3 ₅ 4- and. 5 carries rollers "6" at the bottom near their longitudinal ends. "" These rollers 6 sit on running rails '7,' which are arranged on the side of the underframe 1 of the coil transport vehicle. The outer hoods 3 and 5 have an actuating lever 8 at their front end at the bottom of each longitudinal side of the carriage. In the exemplary embodiment, the shaft 9 simultaneously serves as an axis for the roller 6. To the right or left of the roller 6, a non-rotatable two-armed release lever 10 is also arranged on the shaft. A locking cam 12 is arranged vertically below the shaft 9 on a bracket 11 of the hood 3 or 5 '' which also serves to support the shaft. On the underframe of the coil transport wagon, near its longitudinal ends and near the ends of the individual hoods 3, 4 and 5 locking pawls 13 are arranged, which are vertically pivotable about a horizontal shaft 14 arranged in the wagon transverse axis in the underframe. These pawls protrude between the rails 7 of the hoods 3? 4 and 5 and are arranged in the sliding plane of the locking cams 12. A lever 15 is attached to the shaft 14 and carries a spring 16 at its free end

the other end on the underframe of the coil transport trolley "is attached and the pawl urges upwards. In the closed position of the hoods 3? 4 · and 5 are the Locking cams 12 of the outer hoods 3 and 5 on the front side in front of the pawls 13 and thereby lock the hoods 3 »4 and 5 ·

If the hoods 3 »4 and 5 are to be opened from an end wall 2, the actuating lever 8 of an outer hood 3 or 5 is pivoted in the sliding direction. By pivoting the actuating lever 8, the release lever 10, which is non-rotatably connected to the actuating lever 8, is pivoted at the same time. The release lever 10 presses with its axis directed towards the carriage transverse free end of the pawl 13 vertically downwards, so that ^r of the sliding away of the hood 3 or 5 is released. Through the connection of the pawls 13 on both longitudinal sides by the carriage shaft 14 are both the Haube- 3 or 5 locking pawl 13 gelöst..Die hood 3 or 5 can o'etzt i ⁿ the opening direction to be moved. If the hood 3 or 5 is shifted in the opening direction so far that a section of the cargo space is exposed, the locking cam 12 of the outer hood 3 or 5 runs against the pawl I3 attached to the underframe 1 near the middle hood 4 and against its run-up bevel 17 and the pawl 13 pivots vertically downwards, so that the further displacement path of the hood 3 or 5 is released. If the locking cam 12 has moved over the locking pawl 13, the locking pawl I3 is pivoted upwards again by the force of the spring 16, as a result of which the sliding path of the hood 3 or 5 in the closing direction is blocked. When the hood 3 or 5 is moved further in the opening direction, the middle hood 4- is displaced against one another in the opening direction by the sealing profiles at the ends of the hoods resting against each other. Are the hoods 3 or. 5 rait the hood 4- shifted so far that two sections of the cargo space are exposed, the locking cam 12 of the hood 3 or 5 runs again against the run-up bevel 17 of a pawl mounted on the underframe and swings it vertically downwards. If this pawl I3 is run over,
