Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck leveling technology, specifically a refrigerated truck with a slope self-leveling unloading function. Background Technology

[0002] Refrigerated trucks are enclosed van-type transport vehicles used to maintain the temperature of frozen or fresh goods. They are specialized refrigerated transport vehicles equipped with refrigeration units and polyurethane insulated compartments. Refrigerated trucks can be classified according to manufacturer, chassis load capacity, and compartment type. Chinese Patent No. CN202421869724.5 discloses an energy-saving refrigerated truck compartment, belonging to the field of refrigerated truck compartment technology. This energy-saving refrigerated truck compartment includes a refrigerated compartment and energy-saving barrier components. A door is installed on the rear side of the compartment; the floor plate is installed on the bottom wall of the compartment near the door, and a door frame is installed on the floor plate. The door frame is connected to the side wall and inner top wall of the compartment. A folding door is installed inside the door frame. The folding door, the compartment, and the door form a waiting area. The waiting area formed by the folding door allows the main compartment to be divided into a refrigerated compartment and a waiting area. Staff first enter the waiting area through the door to prevent the refrigerated compartment from being directly exposed to the outside environment, which would cause a rapid change in the internal temperature. This ensures that the temperature inside the refrigerated compartment will not change rapidly when staff enter or exit the compartment. The isolated waiting area also reduces the rate at which cold air inside the compartment escapes through the door.

[0003] Based on the above, the inventors have discovered the following problems: the above device can reduce the rate at which cold air inside the compartment escapes through the compartment door, but it ignores the problem that when unloading refrigerated trucks on slopes, the refrigerated truck body is tilted, making it inconvenient to unload the transported goods inside the refrigerated truck, especially for meat transport.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7 This utility model provides a technical solution.

[0024] Example

[0025] In this embodiment, a refrigerated truck with a ramp self-leveling unloading function includes a vehicle body, a refrigerated compartment 1 at the upper end of the vehicle body, a water tank 2 on the vehicle body and located on one side of the refrigerated compartment 1, the water tank 2 having an adjustment component, an installation plate 3 at the top inside the refrigerated compartment 1, a support frame 7 at the center of the lower end of the installation plate 3, a connecting plate 4 at the lower end of the support frame 7, a ring conveyor belt 5 at the lower end of the connecting plate 4, several hooks 6 at the lower end of the ring conveyor belt 5, an electric reel 9 at the center of the upper end of the installation plate 3, a steel rope 10 wound on the electric reel 9, the center of the steel rope 10 being fixedly connected to the electric reel 9, guide wheels 8 movably provided on both sides of the installation plate 3, and pulley components 11 movably provided on both sides of the upper end of the connecting plate 4, with pulleys movably provided inside the pulley components 11, the two ends of the steel rope 10 passing through the guide wheels 8 and the pulleys inside the pulley components 11 respectively and connected to the lower end of the installation plate 3;

[0026] The electric reel 9 rotates clockwise, causing one side of the steel rope 10 at the upper end of the slope to be released on the electric reel 9, and the other side of the steel rope 10 at the lower end of the slope to be wound on the electric reel 9. This causes one side of the connecting plate 4 at the upper end of the slope to descend, while the other side of the connecting plate 4 at the lower end of the slope rises. The magnitude of the rise and fall is equal to the magnitude of the movement of the rack 15, so that the connecting plate 4 is always in a horizontal state, making the unloading operation of the workers smoother.

[0027] The regulating component includes a liquid. The water tank 2 contains the liquid. A movable groove 12 is provided on one side of the inner wall of the water tank 2. A movable rod 13 is provided in the movable groove 12. A floating plate 14 is provided on the movable rod 13 facing the inside of the water tank 2. A rack 15 is provided at the upper end of the movable rod 13. The rack 15 meshes with a gear 16. A connecting shaft 17 is provided on the gear 16. One end of the connecting shaft 17 is connected to a rotating disk 20. A connecting frame 19 is provided on one side of the water tank 2. A sensing receiving disk 22 is provided on the side of the connecting frame 19 facing the rotating disk 20. A comprehensive processor 18 is provided on the connecting frame 19. A marker 21 is provided on the side of the rotating disk 20 facing the sensing receiving disk 22.

[0028] With the liquid design inside the water tank 2, when the refrigerated truck is on a slope, the position of the upper surface of the liquid inside the water tank 2 changes. When the liquid surface on one side of the movable tank 12 rises or falls, the floating plate 14, which is made of a low-density material such as foam, can move in the same direction. The rising of the floating plate 14 is due to the buoyancy of the liquid, and the falling of the floating plate 14 is due to the weight of the moving rod 13 connected to it. The sum of the frictional forces between the rack 15, the moving rod 13, the floating plate 14, and the moving rod 13 and the movable tank 12 is much less than the buoyancy of the liquid in the water tank 2. This can drive the gear 16 to rotate in the same direction, that is, drive the connecting shaft 17 and the rotating disk 20 to rotate in the same direction. The marker 21 also rotates. The sensing receiver 22 is used to capture the movement trajectory of the marker 21 and then transmit the data to the integrated processor 18 for data processing.

[0029] The pulley 11 is vertically aligned with the guide wheel 8, and the guide wheel 8 is provided with a stop shaft. The vertical alignment of the pulley 11 with the guide wheel 8 makes the movement of the steel rope 10 smoother and the movement of both ends of the connecting plate 4 more stable. The stop shaft on the guide wheel 8 can limit the steel rope 10 to the guide wheel 8, so that the steel rope 10 will not detach from the guide wheel 8 during operation and refrigerated truck travel, thus affecting the movement of the connecting plate 4.

[0030] The rotating disk 20 is horizontally aligned with the sensing receiving disk 22;

[0031] By aligning the rotating disk 20 and the sensing receiving disk 22 horizontally, the sensing receiving disk 22 can fully capture the movement trajectory of the marker 21 on the rotating disk 20 and transmit the movement trajectory information of the marker 21 to the integrated processor 18 for data processing.

[0032] The water tank 2 is provided with a pair of connecting rods at its upper end, and both of the connecting rods are movably connected to the connecting shaft 17.

[0033] The design of a pair of connecting rods can support and limit the connecting shaft 17 without hindering its rotation. The connection between the connecting shaft 17 and the connecting rods can be made smoother by setting a bearing at the connection point.

[0034] The integrated processor 18 includes a signal processor, and the motor on the electric reel 9 is equipped with an actuator. The signal processor and the actuator are communicatively connected.

[0035] The aforementioned signal processor can transmit the signal processed in the integrated processor 18 to the actuator, which then drives the motor on the electric reel 9.

[0036] The integrated processor 18 is electrically connected to the induction receiving disk 22, and the electric reel 9 is electrically connected to the actuator.

[0037] The aforementioned integrated processor 18 can analyze and process the signals received by the induction receiving disk 22, and the aforementioned actuator can drive the motor on the electric reel 9 to rotate.

[0038] Working principle: When the refrigerated truck is on a slope, the position of the upper surface of the liquid in the water tank 2 changes. When the liquid surface on one side of the movable channel 12 rises or falls, the floating plate 14, designed as a low-density material similar to foam, moves in the same direction. The rising of the floating plate 14 is due to the buoyancy of the liquid, and the falling of the floating plate 14 is due to the weight of the moving rod 13 connected to it. Furthermore, the sum of the frictional forces between the rack 15, the moving rod 13, the floating plate 14, and the movable channel 12 is much less than the buoyancy of the liquid in the water tank 2. It can drive gear 16 to rotate in the same direction, that is, drive connecting shaft 17 and rotating disk 20 to rotate in the same direction, and the marker 21 also rotates. The sensing receiver disk 22 is used to capture the motion trajectory of marker 21 and then transmit the data to the integrated processor 18 for data processing. The integrated processor 18 sends a signal to the actuator on the electric reel 9. The actuator drives the electric reel 9 to rotate in the same degree and direction, causing the steel rope 10 on both sides to wind and release on the electric reel 9, thereby causing the pulleys 11 connected to both ends of the steel rope 10 to rise and fall respectively. Figure 3 As shown, the support frame 7 is movably connected to the connecting plate 4, so that both ends of the connecting plate 4 can work in the same direction. Then, the connecting plate 4 can be adjusted according to the slope of the slope to keep the connecting plate 4 in a horizontal state. Combined with the design of the ring conveyor belt 5 and the hook 6, the unloading operation of the workers can be smoother. The hook 6 is used to place the transported object.

[0039] Specifically, the liquid rises at the floating plate 14, causing the rack 15 to rise, which in turn causes the gear 16 to rotate clockwise, and the marker 21 to rotate clockwise. Through the design of the marker 21, the sensor receiver 22, the integrated processor 18, and the actuator, the electric reel 9 rotates clockwise in the same direction, causing one side of the steel rope 10 at the upper end of the slope to be released on the electric reel 9, and the other side of the steel rope 10 at the lower end of the slope to be wound up on the electric reel 9. This causes one side of the connecting plate 4 at the upper end of the slope to descend, while the other side of the connecting plate 4 at the lower end of the slope rises. The magnitude of the rise and fall is equal to the magnitude of the movement of the rack 15, so that the connecting plate 4 is always in a horizontal state, making the unloading operation of the workers smoother.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
