Abstract
The utility model discloses a hydraulic controlled top cover mechanism of a dump semi-trailer, which comprises a top cover. The top cover comprises a left set of a left upper cover and a left side cover and a right set of a right upper cover and a right side cover, each upper cover is connected with each side cover integrally through hinges, the left side cover and the right side cover are connected with a side plate of a carriage through hinges, the left upper cover and the right upper cover are both provided with swing arms connected with the side plate of the carriage, one end of each swing arm is hinged with the side plate of the carriage while the other end of the swing arm is hinged with each upper cover, and the swing arms are also connected with a power device. Goods scattering can be avoided by the aid of the top cover, thereby not only avoiding waste but reducing environmental pollution. Further, the top cover can be opened and closed through a hydraulic mechanism, and a driver can operate the top cover conveniently, so that labor intensity of workers is reduced and operation safety is increased. Furthermore, the top cover has a function of limiting overload of goods and reducing emission of vehicle tail gas. In addition, the hydraulic controlled top cover mechanism is simple and practical in structure, fine in sealing effect and long in service life.
Description
Technical field
The utility model belongs to the dumping car technical field, is specifically related to a kind of self-discharging semitrailer hydraulic control top cover mechanism.
Background technology
Self-discharging semitrailer is through being commonly used to transport bulk goods, and (as: coal, coke, house refuse, building waste, sand, soil, stone and other powder goods), because most of cars do not dispose top cover, bulk goods very easily causes and flies on the way to spread, and has both caused waste, again contaminated environment.Some driver is under the driving of economic interests, and goods overload phenomenon is very serious, the emission of automobile wastes amount is exceeded standard greatly, and also cause traffic accident easily.Though some car is added a cover tarpaulin, waste time and energy poor sealing performance.For this reason, the continuous feedback opinion of user, hope can be disposed top cover for self-discharging semitrailer, to overcome above-mentioned defective.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved in the utility model is that a kind of self-discharging semitrailer hydraulic control top cover mechanism that realizes the automatic folding purpose of self-discharging semitrailer top cover is provided.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of self-discharging semitrailer hydraulic control top cover mechanism, comprise top cover, described top cover comprises upper top cover and the side cover that left and right two covers are connected in one by hinge, described and arranged on left and right sides lid is connected with the compartment side plate by hinge, and left and right two upper top covers are provided with the swing arm that links to each other with the compartment side plate, and described swing arm one end and compartment side plate are hinged, the other end and upper top cover are hinged, and described swing arm is connected with engine installation.
Above-mentioned self-discharging semitrailer hydraulic control top cover mechanism, described engine installation comprises two-way hydraulic cylinder, connect tooth bar respectively on the both sides push rod of hydraulic actuating cylinder, tooth bar is connected with gear matched on being arranged on swing arm, described gear is fixed in the gear case, rotates the swing arm swing and the gear wheel shaft of connection gear is fixed with gear.
The advantage of a kind of self-discharging semitrailer hydraulic control of the utility model top cover mechanism is:
1, because the configuration top cover can prevent that bulk goods from scattering, both avoided waste, reduced pollution again environment.
2, top cover can rely on the automatic folding of hydraulic gear, and chaufeur can be operated easily, has alleviated working strength of workers greatly, has increased the safety of operation.
3, top cover is set, can reaches the effect of restriction goods overload, and the motor vehicle exhaust emission amount is reduced.
4, simple and practical, good seal, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model self-discharging semitrailer hydraulic control top cover mechanism;
Fig. 2 is an A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details;
As shown in Figure 1, structural representation for self-discharging semitrailer hydraulic control top cover mechanism, it comprises top cover 1, described top cover 1 comprises a left side, upper top cover 11 and side cover 12 that right two covers are connected in one by hinge 2, upper top cover 11 comprises left top cover 111, right top cover 112, upper top cover is 11 structures of opening to both sides from the centre, side cover 12 comprises left cap 121, right cap 122, described left cap 121, right cap 122 is connected with compartment side plate 3 by hinge 2, left side top cover 111 is provided with the swing arm 4 that links to each other with compartment side plate 3 with right top cover 112, described swing arm 4 one ends and compartment side plate 3 are hinged, the other end and left top cover 111 are hinged, simultaneously, another swing arm 4 and right top cover 112 are hinged, and described swing arm 4 is connected with engine installation.Described engine installation comprises two-way hydraulic cylinder 5, connect tooth bar 7 respectively on the both sides push rod 6 of hydraulic actuating cylinder 5, tooth bar 7 is connected with the gear 8 that is arranged in the swing arm 4, and described gear 8 is fixed in the gear case 9, rotates the swing arm 4 of swinging with gear 8 and fixes with the gear wheel shaft 10 of connection gear 8.
When uncapping, hydraulic actuating cylinder 5 promotes push rod and moves from left to right, and tooth bar 7 driven gears 8 that are connected as a single entity with push rod rotate, and make swing arm 4 swings, and left top cover 111, right top cover 112 are opened.Close when covering, the B mouth oil-feed of hydraulic actuating cylinder 7, the oil return of A mouth, the motion of push rod right-to-left, tooth bar 6 driven gears 5 rotate, and make swing arm 4 swings, and left top cover 111, right top cover 112 are closed.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
