Description

Technical Field

[0001] This application relates to the field of express delivery, and more specifically, to a loading and conveying device for express delivery trucks. Background Technology

[0002] In the express delivery process, trucks are the primary means of transportation. Express trucks need to efficiently and accurately load parcels from various sorting centers into their cargo boxes before transporting them to different destinations. Currently, some loading conveyor systems on the market have relatively simple designs and cannot adapt to trucks of different heights. Different models of express trucks have varying cargo box heights, while existing conveyor systems have fixed heights. When faced with trucks of different heights, they cannot smoothly transport parcels into the cargo boxes, requiring adjustments with other auxiliary equipment, increasing operational complexity and cost. Furthermore, the loading conveyor system lacks stable support at the front end in its structural design. During the transportation of parcels, especially when transporting heavy or large parcels, the conveyor system is prone to shaking or tilting, affecting the stability and accuracy of the transport, and may even cause parcels to fall and be damaged. Utility Model Content

[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0004] The purpose of this application is to address the shortcomings of existing technologies by providing a loading and conveying device for express delivery trucks. This addresses the problem that existing conveying devices have a fixed height, making it impossible to smoothly transport express parcels into the cargo box when dealing with trucks of different heights. This necessitates adjustments using other auxiliary equipment, increasing operational complexity and cost.

[0005] To achieve the above objectives, this application provides the following technical solution: A loading and conveying device for a delivery truck includes a cargo box and a conveyor frame, the conveyor frame being inserted into the rear of the cargo box, a conveyor belt being provided on the inner side of the conveyor frame, and raised strips being provided on the surface of the conveyor belt. A drive motor for rotating the conveyor belt is installed on the side wall of the conveyor frame. A support frame is installed at the lower part of the bottom of the conveyor frame, and a support assembly and a tilting frame are installed at the higher part. The support components are spaced apart, and the tilting frame is located near the end face of the conveyor frame. The support components include mounting rods and pressure rods. The mounting rods are symmetrically distributed in pairs at the bottom of the conveyor frame. A drive rod is slidably installed inside one set of mounting rods, and an inner slide rod is slidably installed inside the other set of mounting rods. The bottom of the inner slide rod and the drive rod are respectively connected to the two sides of the pressure rod.

[0006] Preferably, the pressure rod is horizontally positioned and rises and falls synchronously with the drive rod, the pressure rod contacts the bottom inner wall of the cargo box, and the upper surface of the drive rod has a threaded hole.

[0007] Preferably, an internal screw is rotatably installed in the mounting rod corresponding to the position of the drive rod, and the internal screw is threadedly connected to the drive rod.

[0008] Preferably, an adjusting shaft is installed on the side wall of the mounting rod. The adjusting shaft rotates and transmits the rotational force into the interior of the mounting rod. The adjusting shaft and the internal screw are vertically distributed and each is equipped with vertically distributed and meshing bevel teeth.

[0009] Preferably, the bottom of the conveyor frame has a protruding mounting block, the flipping frame is rotatably connected to the protrusion, and the end of the flipping frame away from the protrusion is movably fitted with a mounting block.

[0010] Preferably, the interior of the flipping frame has a sliding hole for the extension rod to slide into, the side wall of the flipping frame has a locking hole, and the outer wall of the extension rod is equipped with an elastic buckle, which is adapted to engage with the locking hole.

[0011] Preferably, the bottom of the extension rod and the support frame are respectively equipped with casters.

[0012] The beneficial effects of this application are as follows: By setting up a support component, the height of the front end of the conveyor frame can be flexibly adjusted to adapt to truck cargo boxes of various heights. This avoids the need for additional conveying equipment or auxiliary tools due to different truck heights. When conveying express parcels, especially heavier or larger parcels, stable support effectively prevents the conveyor device from shaking or tilting, ensuring a smooth conveying process. This not only improves the accuracy and efficiency of conveying but also greatly reduces the risk of express parcels falling and being damaged due to device instability, ensuring the safety of goods. When the conveyor frame is not in use, the tilting frame can be flipped into a vertical device, working together with the support frame to provide stable support for the whole, ensuring the stability of the device during non-use and preventing damage or deformation due to external forces. When the conveyor frame needs to be used, the tilting frame can be flipped and retracted, without obstructing the movement of the conveyor frame towards the cargo box, ensuring smooth loading operations.

[0020] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Reference Figure 1-2 As shown, this utility model provides a loading and conveying device for express delivery trucks, including a cargo box 1 and a conveyor frame 2. The conveyor frame 2 is inserted into the rear of the cargo box 1. A conveyor belt 4 is provided on the inner side of the conveyor frame 2. The surface of the conveyor belt 4 is provided with protruding strips 5. A drive motor 6 for driving the conveyor belt 4 to rotate is installed on the side wall of the conveyor frame 2.

[0022] Reference Figure 3 The support components 3 are spaced apart, and the tilting frame 15 is located near the end face of the conveyor frame 2. The support components 3 include mounting rods 12 and pressure rods 10. The mounting rods 12 are symmetrically distributed in pairs at the bottom of the conveyor frame 2. One set of mounting rods 12 has a drive rod 8 slidably mounted inside, and the other set of mounting rods 12 has an inner slide rod 11 slidably mounted inside. The inner slide rod 11 and the bottom of the drive rod 8 are respectively connected to the two sides of the pressure rod 10. The pressure rod 10 is horizontally set and rises and falls synchronously with the drive rod 8. The pressure rod 10 contacts the bottom inner wall of the cargo box 1. The upper surface of the drive rod 8 has a threaded hole. An inner screw is rotatably mounted in the mounting rod 12 corresponding to the position of the drive rod 8. The inner screw is threadedly connected to the drive rod 8. An adjusting shaft 7 is installed on the side wall of the mounting rod 12. The adjusting shaft 7 rotates and enters the mounting rod 12. The adjusting shaft 7 and the inner screw are vertically distributed and each is equipped with vertically distributed and meshing bevel teeth.

[0023] Reference Figure 4 A support frame 18 is installed at the lower part of the bottom of the conveyor frame 2, and a support assembly 3 and a tilting frame 15 are installed at the higher part. A mounting block 13 protrudes from the bottom of the conveyor frame 2, and the tilting frame 15 is rotatably connected to the protrusion. The end of the tilting frame 15 away from the protrusion is movably fitted. The interior of the tilting frame 15 has a sliding hole for the extension rod 14 to slide into. A locking hole is provided on the side wall of the tilting frame 15, and an elastic buckle 16 is installed on the outer wall of the extension rod 14, which is fitted and engaged with the locking hole. Casters 17 are respectively installed at the bottom of the extension rod 14 and the support frame 18.

[0024] Working Principle: This loading and conveying device for express delivery trucks operates by placing express packages on the conveyor belt 4 inside the conveyor frame 2 during loading. The conveyor belt 4 has protruding strips 5 on its surface, which increase the friction between the conveyor belt 4 and the express packages, preventing them from slipping or falling during transport. The drive motor 6, mounted on the side wall of the conveyor frame 2, is activated, causing the conveyor belt 4 to rotate (working on the principle of a conventional conveyor line). This transports the express packages placed on the conveyor belt 4 along the conveyor frame 2 into the cargo box 1, achieving automatic loading of express packages and effectively reducing the labor intensity of manual handling.

[0025] Because the height of the cargo box 1 varies among different models of express delivery trucks, a support assembly 3 is provided to enable the conveyor frame 2 to adapt to trucks of different heights. The support assembly 3 includes mounting rods 12 and pressure rods 10. The mounting rods 12 are symmetrically distributed in pairs at the bottom of the conveyor frame 2. A drive rod 8 is slidably installed inside one set of mounting rods 12, and an inner slide rod 11 is slidably installed inside the other set of mounting rods 12. The inner slide rod 11 and the bottom of the drive rod 8 are respectively connected to the two sides of the pressure rod 10. When it is necessary to adjust the height of the conveyor frame 2 to adapt to trucks of different heights, the adjusting shaft 7 installed on the side wall of the mounting rod 12 is rotated. The rotation of the adjusting shaft 7 is transmitted into the interior of the mounting rod 12 and is connected to the inner screw rod installed in the mounting rod 12 at the corresponding position of the drive rod 8 through vertically distributed and meshing bevel teeth. When the adjusting shaft 7 is rotated, the bevel gear drives the inner screw to rotate. Since the inner screw is threadedly connected to the drive rod 8, the drive rod 8 will rise or fall along the mounting rod 12 under the action of the inner screw. The pressure rod 10 rises and falls synchronously with the drive rod 8. The pressure rod 10 is set horizontally and contacts the bottom inner wall of the cargo box 1. Therefore, the rise and fall of the drive rod 8 will drive the pressure rod 10 to rise and fall synchronously, thereby adjusting the height of the front end of the conveyor frame 2 so that it can be well adapted to the cargo boxes 1 of trucks of different heights, ensuring the stability of the conveyor frame 2 when conveying express parcels.

[0026] The tilting frame 15 is located near the end face of the conveyor frame 2. Its main function is to support the entire conveyor frame 2 when it is not in use. When the conveyor frame 2 is used in conjunction with the cargo box 1, it can be tilted and folded up to avoid obstructing the movement of the conveyor frame 2 toward the cargo box 1. When the conveyor frame 2 is not in use, the tilting frame 15 is tilted downwards around the rotating connection point with the mounting block 13 protruding from the bottom of the conveyor frame 2, making it a vertical device. At this time, the tilting frame 15 and the support frame 18 together provide support for the conveyor frame 2, ensuring the stability of the conveyor frame 2 when it is not in use. The tilting frame 15 and the support frame 18 can be connected by bolts.

[0027] When the conveyor frame 2 needs to be used in conjunction with the cargo box 1 for express delivery loading, the tilting frame 15 is tilted and retracted. The tilting frame 15 has a sliding hole for the extension rod 14 to slide into. During the retraction of the tilting frame 15, the position of the extension rod 14 within the sliding hole is adjusted. An elastic buckle 16 is installed on the outer wall of the extension rod 14, and a locking hole is provided on the side wall of the tilting frame 15. When the extension rod 14 is adjusted to the appropriate position, the elastic buckle 16 engages with the locking hole, fixing the position of the extension rod 14. Thus, after the tilting frame 15 is retracted, the conveyor frame 2 can move smoothly towards the interior of the cargo box 1 without being obstructed by the presence of the tilting frame 15. Simultaneously, the bottom of the extension rod 14 and the support frame 18 are respectively equipped with casters 17, facilitating the movement and adjustment of the conveyor frame 2 between different positions.
