Description
Technical Field
The utility model belongs to the technical field of freight transportation equipment, a semi-mounted dump truck railway carriage or compartment door anti-expansion device is related to.
Background
The semi-trailer dump truck carriage door is generally of a hanging door structure, when the semi-trailer dump truck carriage door is unloaded, the carriage body is overturned, the carriage door can be automatically opened to facilitate unloading of materials in the semi-trailer dump truck carriage door, however, when the materials in the semi-trailer dump truck carriage are too much, the material pressure is high, the carriage door is extruded, a latch on the carriage door cannot well fix the lower end of the carriage door, and when the semi-trailer dump truck is transported, the lower end of the carriage door can be expanded to cause leakage of the materials.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a semi-mounted dump truck carriage door anti-expansion device to the problem that prior art exists.
The utility model discloses a concrete technical scheme as follows:
the semi-trailer tipping wagon door anti-expansion device comprises two fixing plates arranged in parallel and a baffle arranged between the two fixing plates, wherein a strip-shaped groove is formed in the middle of each fixing plate, an open groove is formed in the upper end of each fixing plate, a movable rotating shaft is arranged in the middle of each baffle, two ends of each movable rotating shaft are located in the strip-shaped grooves, and a fixed pin shaft matched with the open groove is arranged on the upper portion of each baffle.
The utility model discloses following beneficial effect has:
the utility model discloses block semi-mounted dump truck railway carriage or compartment door lower extreme, can prevent that the railway carriage or compartment door from receiving the material extrusion to expand and cause the material to reveal, simultaneously, the utility model discloses open swiftly convenient, do not influence the operation of unloading of semi-mounted dump truck.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a usage state diagram of the present invention.
Detailed Description
The semi-trailer dump truck compartment door anti-expansion device comprises two fixing plates 1 which are arranged in parallel and a baffle 2 arranged between the two fixing plates 1, wherein a strip-shaped groove 3 is formed in the middle of each fixing plate 1, an open groove 4 is formed in the upper end of each fixing plate 1, a movable rotating shaft 5 is arranged in the middle of each baffle 2, two ends of each movable rotating shaft 5 are located in the corresponding strip-shaped groove 3, each movable rotating shaft 5 can move along the corresponding strip-shaped groove 3, each movable rotating shaft 5 can rotate, and a fixed pin shaft 6 matched with the corresponding open groove 4 is arranged on the upper portion of each baffle 2.
As shown in fig. 2, the fixing plate 1 of the present invention is installed on the lower wall 7 of the cargo box, the upper end of the car door 8 is hinged to the upper wall 9 of the cargo box, when the car door 8 is in a closed state, the fixing pin 6 is inserted into the open slot 4, the baffle 2 is fixed on the fixing plate 1, the upper end of the baffle 2 is higher than the lower wall 7 of the cargo box and blocks the lower end of the car door 8, so as to prevent the material in the cargo box from excessively extruding the car door 8 to expand; when the compartment door 8 needs to be opened for unloading, the baffle 2 moves upwards relative to the fixing plate 1, the fixing pin shaft 6 is separated from the open slot 4, then the baffle 2 is overturned relative to the fixing plate 1, the blocking of the baffle 2 to the lower end of the compartment door 8 is removed, and the compartment door 8 can be overturned upwards to open the cargo compartment of the semitrailer.
