Abstract
A dump truck exhaust pressure reduction device comprises a pressure reducing box arranged on a longitudinal crossbeam at the bottom of a truck. A first end sealing plate and a second end sealing plate are arranged on the two axial end faces of the pressure reducing box respectively, one end of a connecting pipe is communicated with the pressure reducing box through a middle circular hole of the first end sealing plate, and a flange is arranged at the other end of the connecting pipe. One end of a gas outlet pipe is communicated with the pressure reducing box through a circular hole formed in the position, close to the second end sealing plate end, of the radial side of the pressure reducing box. The dump truck exhaust pressure reduction device can reduce dump truck exhaust emission pressure and change the exhaust emission direction, and therefore pollution influence on the environment is reduced, and the device is beneficial to the body health of constructors and on-site civilized construction.
Description
Technical field
The utility model relates to automobile equipment field, is especially a kind ofly applicable to the heavy dump truck tail gas dropping equipment that construction site that dust is many is used.
Background technology
In building engineering construction, the heavy dump truck engine power using is strong, the tail gas pressure that freeing pipe is discharged is large, and the Way out of freeing pipe mostly is oblique following formula (being oblique ground direction), the tail gas of therefore discharging directly blows to ground, causes while moving in the many workyards of dust, the very large dust of can kicking up, serious environment pollution, had both been unfavorable for the healthy of site operation personnel, was also unfavorable for civilized construction.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of dumping truck tail gas dropping equipment, can reduce dumping truck exhaust emissions pressure, change the direction that tail gas is discharged, thereby alleviate the pollution effect to environment, be conducive to workmen's healthy and on-the-spot civilized construction.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of dumping truck tail gas dropping equipment, comprise the step-down case on the longitudinal girder that is arranged on bottom of car, two axial ends of step-down case are respectively arranged with the first head plate and the second head plate, connection pipe one end is communicated with step-down case by the middle part circular hole of the first head plate, and the other end of connection pipe is provided with flange;
Freeing pipe one end is communicated with step-down case near the circular hole of the second head plate end by being opened in step-down case radial side.
The radial side of step-down case is provided with multiple tracks anchor ear, is connected with stay cord on anchor ear, and step-down case is arranged on the longitudinal girder of bottom of car by anchor ear and stay cord.
The internal diameter of freeing pipe is greater than the internal diameter of connection pipe.
The dumping truck tail gas dropping equipment that the utility model provides, by connection pipe, be connected with the freeing pipe of automobile, dumping truck tail gas is discharged from freeing pipe after step-down case, can reduce dumping truck exhaust emissions pressure, change the direction that tail gas is discharged, avoid tail gas directly discharged to the impact on ground, thereby alleviated the pollution effect to environment, be conducive to workmen's healthy and on-the-spot civilized construction; Step-down case is connected to by anchor ear and stay cord on the longitudinal girder of bottom of car, solid and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is birds-eye view of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the right elevation of the utility model Fig. 2;
Fig. 4 is the upward view of the utility model while being installed on tip car.
The specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises the step-down case 1 on the longitudinal girder that is arranged on bottom of car, two axial ends of step-down case 1 are respectively arranged with the first head plate 1-1 and the second head plate 1-2, connection pipe 2 one end are communicated with step-down case 1 by the middle part circular hole of the first head plate 1-1, and the other end of connection pipe 2 is provided with flange 5;
Freeing pipe 3 one end are communicated with step-down case 1 near the circular hole of the second head plate 1-2 end by being opened in step-down case 1 radial side.
The radial side of step-down case 1 is provided with multiple tracks anchor ear 4, is connected with stay cord 6 on anchor ear 4, and step-down case 1 is arranged on the longitudinal girder of bottom of car by anchor ear 4 and stay cord 6.
The internal diameter of freeing pipe 3 is greater than the internal diameter of connection pipe 2.
It is of the present utility model that to install and use process as follows:
As shown in Figure 4, first disassemble the latter end of the freeing pipe 8 of former dumping truck 7, then the utility model is installed.During installation, the flange 5 of connection pipe 2 one end (being the entrance point of connection pipe 2) is connected with the flange of the freeing pipe 8 of dumping truck 7, the stay cord on anchor ear 46 is fastened on the longitudinal girder of bottom of car.
During installation, note adjusting the position of tracheae 3, make it keep horizontality.
