Technical Field

[0001] The utility model relates to the technical field of transport vehicles, in particular to a muck truck with a carriage protection device. Background Technique

[0002] In recent years, with the continuous development of domestic urban construction, muck trucks in cities have become a "chronic problem" in urban construction due to reasons such as overloading, leakage, and loud noise. However, with the rapid development of cities and a large number of construction projects for building engineering and highway engineering, the use of muck trucks, which are essential in project construction, is also increasing.

[0003] During the process of muck transportation, a dust-proof tarpaulin needs to be covered on the top of the carriage of the muck truck to reduce the pollution generated during transportation. Most of them use tarpaulins to cover the top of the carriage. However, when the tarpaulin covers the muck, it cannot completely cover the muck. Since there are gaps between the dust-proof tarpaulin and the side baffles on both sides of the carriage, when loading the muck, it is usually fully loaded in a small mountain shape, resulting in the muck being very easy to fall on the ground through the side baffles of the carriage during transportation, causing serious pollution to the urban environment and also having a great impact on the driving safety of other vehicles.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0019] The present utility model provides a muck truck with a carriage protection device, including a muck truck 1, a carriage 2 is installed on the muck truck 1. Grooves 3 are formed on the upper end surfaces of both side walls of the carriage 2, and a protection plate 4 is provided in the groove 3. The upper end of the protection plate 4 extends out of the groove 3;

[0020] The carriage 2 can temporarily store the construction waste, which facilitates the transfer by the dump truck 1. The protective plate 4 is slidably installed in the groove 3. When the protective plate 4 slides outward of the groove 3, it can protect the two side walls of the carriage 2, preventing the construction waste from falling outside the carriage 2 from the two side walls of the carriage 2 during the transfer of the construction waste, which may cause harm to pedestrians or other vehicles on the road.

[0021] A pair of sliding grooves 5 are formed on the lower end surface of the protective plate 4. A slider 6 is slidably installed in the sliding groove 5. The lower end surface of the slider 6 is hinged with a connecting rod 7. One end of the connecting rod 7 away from the slider 6 is hinged with the lower end surface of the groove 3.

[0022] The slider 6 slides in the sliding groove 5, which can drive the connecting rod 7 to turn, so that it can drive the protective plate 4 to slide out of the groove 3 or retract into the groove 3.

[0023] One connecting rod 7 is hinged with a hydraulic cylinder 8 on its outer surface. The telescopic end of the hydraulic cylinder 8 is hinged with the outer surface of the other connecting rod 7.

[0024] When the telescopic end of the hydraulic cylinder 8 extends, it can drive a pair of connecting rods 7 to turn simultaneously, and at the same time make a pair of sliders 6 slide in a pair of sliding grooves 5 respectively.

[0025] Specifically, an n-shaped plate 9 is fixedly installed at the top end of the protective plate 4. The inner side wall surfaces of both sides of the n-shaped plate 9 are in contact with the outer surface and the inner surface of the side wall of the carriage 2 respectively.

[0026] The n-shaped plate 9 can block the construction waste in the carriage 2, preventing the construction waste from falling into the groove 3 through the gap between the protective plate 4 and the groove 3 and polluting the inside of the groove 3.

[0027] Specifically, a housing 10 is fixedly installed on both sides of the lower end surface of the groove 3. The housing 10 is filled with hydraulic oil.

[0028] A sliding plate 11 is slidably installed in the housing 10. A sliding rod 12 is fixedly installed on the upper end surface of the sliding plate 11. The top end of the sliding rod 12 penetrates the upper wall of the housing 10 and is fixedly installed with a bearing plate 13. The upper end surface of the bearing plate 13 is in contact with the lower end surface of the protective plate 4.

[0029] An elastic member 14 is provided between the housing 10 and the bearing plate 13. The elastic member 14 is wound around the outer surface of the sliding rod 12.

[0030] The elastic member 14 is a compression spring, and its two ends are respectively welded to the upper end surface of the housing 10 and the lower end surface of the bearing plate 13, which can apply an upward force to the bearing plate 13, causing the bearing plate 13 to drive the sliding rod 12, and enabling the sliding plate 11 to slide within the housing 10. When the protective plate 4 descends, the upper end surface of the bearing plate 13 contacts the lower end surface of the protective plate 4. At this time, the elastic member 14 is compressed, and at the same time, the sliding rod 12 drives the sliding plate 11 to slide within the housing 10. At this time, the hydraulic fluid within the housing 10 flows through the gap between the sliding plate 11 and the housing 10, which can play a role in slowing down the descent of the protective plate 4, preventing it from descending too quickly and causing damage to the connecting rod 7.

[0031] Specifically, a pair of bearing blocks 15 are provided on the lower end surface of the groove 3, and the upper end surface of the bearing block 15 contacts the lower end surface of the protective plate 4;

[0032] When the protective plate 4 descends, its lower end surface contacts the upper end surface of the bearing block 15, enabling the bearing block 15 to carry it, and making it more stably disposed within the groove 3.

[0033] Specifically, a number of through holes 16 are formed within the sliding plate 11;

[0034] The through holes 16 can facilitate the flow of the hydraulic fluid within the housing 10.

[0035] Working principle: When the carriage 2 is filled with construction waste, the driver activates a pair of hydraulic cylinders 8. The telescopic ends of the hydraulic cylinders 8 extend, which can simultaneously drive a pair of connecting rods 7 to flip, and at the same time enable a pair of sliders 6 to slide within a pair of chutes 5 respectively. At this time, the flipped connecting rods 7 can cause the protective plate 4 to rise. When the protective plate 4 slides, it can simultaneously drive the n-shaped plate 9 to rise at the same time. At this time, the protective plate 4 and the n-shaped plate 9 can protect the two side walls of the carriage 2, preventing the construction waste within the carriage 2 from falling outside the carriage 2 from the two sides of the carriage 2 when the muck truck 1 is driving, and preventing harm to pedestrians or other vehicles on the road. At the same time, when the carriage 2 has emptied the construction waste, the driver activates a pair of hydraulic cylinders 8, causing their telescopic ends to contract, simultaneously driving a pair of connecting rods 7 to flip, enabling a pair of sliders 6 to slide within a pair of chutes 5 respectively, and causing the protective plate 4 to retract into the groove 3. At this time, the lower end surface of the protective plate 4 contacts the upper end surface of the bearing plate 13. At this time, the elastic member 14 is compressed, and at the same time, the sliding rod 12 drives the sliding plate 11 to slide within the housing 10. At this time, the hydraulic fluid within the housing 10 flows through the gap between the sliding plate 11 and the housing 10 and the through holes 16, which can play a role in slowing down the descent of the protective plate 4, preventing it from descending too quickly and causing damage to the connecting rod 7. At the same time, when the protective plate 4 descends to a certain height, its lower end surface contacts the upper end surface of the bearing block 15, enabling the bearing block 15 to carry it, and making it more stably disposed within the groove 3, bringing convenience to people.
