Description
Technical Field
The utility model relates to the tipper field is an automatic opening device of railway carriage or compartment back door lever type of tipper.
Background
The tipper is through hydraulic system's the certain angle of upwards slope with the carriage through the lift power that makes progress to rely on the special car that the dead weight in carriage resets, but the tipper of present general structure when the uninstallation goods, need staff's manual operation open the locking couple of carriage back door earlier, then just can lift the carriage and uninstall the goods, and wait after the goods uninstallation that the carriage return is closed by the locking couple of staff with the back door again, whole operation process is more loaded down with trivial details and leads to work efficiency not high. The dumper with the general structure at present opens the rear door of the carriage by extruding and impacting the rear door of the carriage by goods when unloading goods, the rear door of the carriage is easy to deform and wear under the condition, the rear door of the carriage is asynchronous with the carriage in the process of returning the carriage, repeated impact force is easy to be generated on the carriage, and the rear door of the carriage and the carriage body can fall off and deform under severe conditions.
Disclosure of Invention
The utility model aims at providing a railway carriage or compartment back door lever type automatic opening device of tipper.
The utility model is realized in such a way, the lever type automatic opening device for the rear door of the carriage of the dump truck is characterized in that a steel wire rope fixing seat is arranged on a crossbeam of a chassis of the dump truck; the bottom of the steel wire rope is arranged on the steel wire rope fixing seat, and the upper end of the steel wire rope is connected with the horizontal transverse lever; the middle part of the horizontal transverse lever is connected with a carriage through a hinge shaft, and the tail end of the horizontal transverse lever is connected with a rear door of a carriage body through a rear door connecting fixing seat; the positioning support is welded and fixed at the upper end of the carriage rear upright post; the latch hook fixing seat is welded and fixed on the lower part of the rear upright post of the carriage, so that the rear door is locked with the side plate of the carriage.
The device is arranged on each side of the carriage.
The front end of the horizontal transverse lever is connected with the steel wire rope fixing seat through a steel wire rope, the tail end of the horizontal transverse lever is connected with the carriage rear door through the rear door connecting fixing seat, and the straightness of the horizontal transverse lever is guaranteed through the positioning support.
The carriage back door is locked with the carriage side plate through the lock hook fixing seat.
Due to the adoption of the technical scheme, the rear door of the carriage is synchronously and automatically opened when the carriage is lifted upwards, so that the impact of goods on the rear door of the carriage and the blockage of the rear door of the carriage on the goods are effectively avoided, the service life of the rear door of the carriage is prolonged, and the unloading work efficiency is greatly improved; when the carriage returns, the carriage rear door keeps synchronous with the carriage return under the action of the tensile force of the steel wire rope, so that the collision of the carriage rear door on the carriage is effectively avoided, the collision deformation generated by the carriage body and the rear door is avoided, and the falling of the carriage rear door is also avoided; and in the whole discharging and carriage returning process, the opening and closing of the carriage body rear door are not required to be manually operated by workers, so that the working efficiency is greatly improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a steel wire rope fixing seat; 2. A wire rope; 3. A horizontal transverse lever; 4. a hinge shaft fixing seat; 5. Positioning a support; 6. the rear door is connected with the fixed seat; 7. a rear door of the carriage; 8. latch hook fixing seat.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
In fig. 1, one end of the inner side of a steel wire rope fixing seat 1 is fixed on a girder connecting web plate of a chassis of the dump truck through welding, and the other end of the outer side of the steel wire rope fixing seat is connected with a steel wire rope 2 through an eyelet bolt; the upper end of the steel wire rope 2 is connected with the front end of the horizontal transverse lever 3 through an eyelet bolt; the middle part of the horizontal transverse lever 3 is connected with a hinge shaft fixing seat 4 welded on the carriage body through a hinge shaft, then a rear door connecting and fixing seat 6 welded at the tail part of the horizontal transverse lever 3 is connected with a rear door 7 of the carriage body, and a positioning support 5 is welded on a rear upright post of the carriage body to ensure the straightness of the horizontal transverse lever 3; the lower end of the rear column of the compartment body is welded with the lock hook fixing seat 8 to lock the rear door 7 of the compartment body, so that material leakage during loading of goods is prevented, and the rear door can be effectively protected from being impacted by the goods at the initial stage of unloading. The lever type automatic opening mechanism for the rear door of the self-discharging carriage is respectively arranged on two sides of the carriage.
The utility model discloses a wire rope fixing base 1, wire rope 2, horizontal transverse lever 3, hinge fixing base 4, back door coupling fixing base 6, carriage back door 7 forms link mechanism with carriage afterbody self turning point, wire rope 2 overturns around wire rope fixing base 1 when the carriage lifts upwards, and produce downward pulling force to horizontal transverse lever 3, make horizontal transverse lever 3 and carriage back door 7 overturn anticlockwise around hinge fixing base 4, thereby realize the ascending automation of carriage back door and open, the striking of goods to the carriage back door and the retardation of carriage back door to the goods when having avoided unloading like this, thereby can not cause the deformation of carriage back door, the life of carriage back door and the efficiency of unloading are improved; when the carriage is reset, the closing of the carriage back door is the reverse process of the opening, and under the action of the downward pulling force of the steel wire rope, the carriage back door and the carriage are kept synchronous when the carriage is reset, so that the collision deformation of the carriage back door to the carriage is effectively avoided, and the falling off of the carriage back door is also avoided; and in the whole discharging and carriage resetting process, the opening and closing of the carriage body rear door are not required to be manually operated by workers, so that the working efficiency is greatly improved.
