Description

Technical Field

[0001] The utility model relates to a transport trolley, in particular to a transport trolley for navel orange picking. Background Art

[0002] In navel orange picking orchards, to facilitate the transfer and transportation of picked navel oranges, mountain track transport vehicles are usually equipped in the orchard to adapt to the complex terrain of the orchard and efficiently transport goods at the same time.

[0003] An orchard track transport vehicle consists of a track, a power source (electric drive or engine drive) for towing the transport vehicle, a sinking prevention plate, a connecting hook, a carrying platform, etc. When in use, the transport trolley is installed on a track suspended above the ground, and the transport trolley is moved to the picking area. People place multiple bins filled with navel oranges on the carrying platform, and the towing device of the transport vehicle drives the carrying platform to move on the track to the unloading area, replacing manual labor for transporting navel oranges after picking. However, in actual use, for a conventional track transport vehicle, the loading and unloading of navel orange bins on the carrying platform need to be completed manually. Loading and unloading multiple bins filled with navel oranges on a carrying platform at a certain height will undoubtedly cause a large workload on the loading and unloading workers and result in low loading and unloading efficiency. At the same time, frequent movement back and forth between the ground and the carrying platform, between the ground and a carrying platform at a certain height, may pose a risk of people or objects falling from the carrying platform. Summary of the Utility Model

[0004] In order to overcome the shortcomings that for a conventional track transport vehicle, the loading and unloading of navel orange bins on the carrying platform need to be completed manually, loading and unloading multiple bins filled with navel oranges on a carrying platform at a certain height will undoubtedly cause a large workload on the loading and unloading workers and result in low loading and unloading efficiency. At the same time, frequent movement back and forth between the ground and the carrying platform, between the ground and a carrying platform at a certain height, may pose a risk of people or objects falling from the carrying platform, the purpose of the utility model is to provide a transport trolley for navel orange picking with a carrying platform that can move outwards and lift, facilitating the loading and unloading of materials.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Although the present utility model may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present utility model. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present utility model as defined by the appended claims. Any numerical labels such as: first or second are merely illustrative and are not intended to limit the scope of the present utility model in any way.

[0020] Embodiment 1: A transport trolley for navel orange picking, as Figures 1-4As shown in the figure, it includes a track 1, a monorail trolley 2, rollers 21, a traction motor 3, a carrying platform 4, a pallet 41, a fixed seat 42, an electric slide rail 43, a lifting group 44, a wire group 45, a guardrail 46 and a fence 47. The track 1 is arranged in the navel orange transportation park as required, and two monorail trolleys 2 are equipped on it. The frame of the monorail trolley 2 is integrally in an inverted C shape, and a connecting block for connecting the carrying platform 4 is provided at its top. The cross-section of the track 1 is in the shape of an I-beam. Two rollers 21 are rotatably provided on both the front and rear sides inside the monorail trolley 2, and the rollers 21 on the front and rear sides are respectively embedded in the grooves on both the front and rear sides of the track 1. The monorail trolley 2 moves on the track 1 through the rollers 21. A traction motor 3 is installed at the front of the left monorail trolley 2, and the traction motor 3 is connected to a roller 21 on the front side inside the monorail trolley 2 and the track 1. The traction motor 3 can rotate forward and backward. Driven by the traction motor 3, the monorail trolley 2 moves on the track. A carrying platform 4 is provided between the two monorail trolleys 2. The carrying platform 4 is not fixedly connected to the monorail trolleys 2 on both sides. A connecting part hinged to the top of the monorail trolley 2 is provided at the lower part of the carrying platform 4. Through the movable connection between the carrying platform 4 and the two monorail trolleys 2, the transport trolley can move more smoothly and smoothly on the curved track 1;

[0021] Among them, as Figures 1-2 shown, fixed seats 42 for stably installing lifting components are provided on both the left and right sides of the carrying platform 4. An electric slide rail 43 is fixedly connected to the top of the fixed seat 42. A lifting group 44 for lifting and lowering the pallet 41 is fixedly connected to the slide plate of the electric slide rail 43. The lifting group 44 consists of a motor and a wire drum. A steel cable is arranged on the wire drum. When the motor of the lifting group 44 works, it will drive the wire drum to rotate, so as to realize the winding and unwinding of the steel cable on the wire drum. One end of the lower part of the steel cable is connected to a wire group 45. The wire group 45 consists of two steel cables. A pallet 41 is suspended between the lower parts of the wire group 45, and the other ends of the two steel cables of the wire group 45 are respectively connected to the front and rear sides of the same side edge of the pallet 41. The pallet 41 will be placed stably on the carrying platform 4. When the motor of the lifting group 44 works, it drives the pallet 41 to move up and down. When the electric slide rail 43 works, it drives the lifting group 44 and the pallet 41 to move back and forth. A guardrail 46 for limiting the placement of the material box is arranged around the top of the pallet 41. A fence 47 that can be rotated and opened during loading and unloading is provided on the guardrail 46 on the front left side of the pallet 41;

[0022] When loading and unloading navel oranges, the lifting group 44 and the pallet 41 are moved out of the space above the transport platform 4 through the electric slide rail 43. Subsequently, the pallet 41 is lowered by the lifting group 44 so that it lands in an area with a lower height and convenient for loading and unloading. At this time, material loading and unloading are carried out. When loading and unloading materials, the working load of workers is effectively reduced, the loading and unloading efficiency is improved, and there is no need to frequently move back and forth between the ground and the transport platform 4 with a certain height, reducing the risk of people and objects falling from the transport platform 4 during loading and unloading.

[0023] Embodiment 2 is based on Embodiment 1. As Figures 1-3 shown, it further includes a braking member 5 and a sensor 51. Braking members 5 for braking the trolley during movement are provided on the rear sides of the monorail trolleys 2. The braking member 5 is fixedly connected to a roller 21 on the rear side of the monorail trolley 2. When the braking member 5 works, the roller 21 connected to it will rotate in the direction opposite to the transmission direction of the transport trolley. At the same time, before that, the traction motor 3 should stop operating. Sensors 51 that emit light rays are provided on both the front and rear sides of the monorail trolley 2, and the sensors 51 are arranged horizontally. The sensors are signal-connected to the traction motor and the braking member.

[0024] Initially, people set up an obstacle on a section of the track 1 where the trolley needs to stop, which can receive the light rays of the sensor 51. When the trolley approaches, when the light rays of the sensor 51 shine on the obstacle, it responds quickly and transmits signals to the braking member 5 and the traction motor 3. The traction motor 3 stops operating, and the braking member 5 works, and the transport trolley stops smoothly. Through the arranged sensor 51, automatic braking is realized, which is more reliable compared with conventional manual braking, reducing the transportation risks caused by workers' misoperations and lagged operations.

[0025] In a specific embodiment: As Figures 1-4 shown, it further includes a buffer push rod 6. Buffer push rods 6 for buffering the braking force are provided on the monorail trolleys 2 near the sensors 51. At the same time, a stop block matching the buffer push rod 6 should be provided on the track 1. The buffer push rod 6 is arranged in the same direction as the sensor 51. By providing the buffer push rod 6 on the transport platform 4, when the transport trolley makes an emergency stop, it can avoid excessive impact loads being transmitted to the transport platform 4, and the huge impact force causes the navel oranges on the pallet 41 to be damaged.

[0026] In a specific embodiment: As Figure 4As shown in the figure, it further includes a backing plate 7 and an elastic member 8. The carrying platform 4 is connected to the backing plate 7 of the two lifting pallets 41 through the elastic member 8. The top of the backing plate 7 contacts the inner side of the lower part of the pallet 41, and the friction between the backing plate 7 and the pallet 41 should be relatively large. When the pallet 41 is filled with materials, the pallet 41 is lifted by the backing plate 8. When transporting materials, the situation of the pallet 41 sliding and shifting on the backing plate 8 is reduced, and the possibility of the stacked navel oranges hitting each other is reduced. At the same time, through the elastic member 8, the vibration and inertia during the movement of the trolley and when being impacted by external forces are diluted, absorbed and dispersed to a certain extent, improving the stability during transportation, reducing the damage of navel oranges caused by the mutual contact and collision between the navel orange boxes, and ensuring the safe transportation of navel oranges.

[0027] In a preferred embodiment: A detachable positioning block is provided on the track 1. By setting the positioning block on a specific section of the track 1, such as at the location for loading and unloading navel oranges, the positioning block is firmly installed on the track 1. When the transport trolley moves, through the cooperation of the positioning block and the sensor 51, the transport trolley is braked in a timely manner. At the same time, through the impact contact between the positioning block and the buffer push rod 6, the trolley can accurately stop in the material loading and unloading area, ensuring that the transport trolley can stop in a timely manner after arriving at the position for loading and unloading navel oranges.

[0028] In a preferred embodiment: Anti-slip patterns for increasing friction and reducing material slippage are provided on the pallet 41. When the box filled with navel oranges is placed on the pallet 41, the provided anti-slip patterns can increase the friction between the box and the pallet 41, thereby reducing the amplitude of the box moving under force on the pallet 41 during transportation and increasing the stability during the transportation of navel oranges.

[0029] Those skilled in the art of this industry should understand that the above embodiments do not limit the present utility model in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
