Technical Field

[0001] This utility model relates to the field of building material transportation technology, and in particular to a small transportation device for construction projects. Background Technology

[0002] Building material transport equipment is responsible for transporting various building materials from the supply location to the construction site in construction projects, ensuring the continuity and efficiency of the construction process.

[0003] Building materials are generally heavy, and unloading them is difficult after loading. When small transport equipment, such as dump trucks, is used to transport building materials, there are safety hazards when construction workers tip over the truck bed, and the equipment is easily damaged.

[0004] In the existing technology, larger hydraulic dump trucks use an electric hydraulic rod to push the truck bed to tilt it to a position close to the ground, thus achieving automatic dumping. However, this method is costly and the truck is large, which limits its use on construction sites. Manual dump trucks are inconvenient for unloading. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a small transportation device for construction engineering.

The cargo box is mounted on the upper side of the trailer plate. A load-bearing wheel is provided on one side of the cargo box, and a support rod is provided on the other side of the cargo box. An inclined opening is provided on the side of the cargo box near the load-bearing wheel. A discharge port is provided at the bottom of the inclined opening. A sealing plate is provided on the discharge port. A limiting device is provided on the side of the sealing plate in the cargo box.

[0008] Preferably, the trailer platform is provided with a lifting wheel assembly at the bottom, the lifting wheel assembly including a lifting wheel, a lifting frame and a linkage control rod; one end of the lifting frame is rotatably connected to the lifting wheel, the other end of the lifting frame is hinged to the linkage control rod, and the trailer platform is provided with a mounting frame hinged to the lifting frame at the bottom.

[0009] Preferably, the handle is connected to the steering wheel, and the trailer plate is provided with a lifting bar on the side near the handle.

[0010] Preferably, the outer side of the truck bed is provided with a support block corresponding to the lifting rod, and the lower side of the support block is provided with a positioning groove adapted to the top of the lifting rod.

[0011] Preferably, a rotary positioner corresponding to the support rod is provided on one side of the truck bed. The rotary positioner includes a turntable and a pin. The support rod is fixedly connected to the turntable, and the turntable is rotatably connected to the truck bed. Pin holes are provided on the turntable and the truck bed.

[0021] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Reference Figure 1-3 A small transport equipment for construction engineering includes a trailer and a detachable cargo box 1 mounted on the trailer. The cargo box 1 is used to load building materials, sand, gravel or cement. The trailer and cargo box 1 can be separated. When loading and unloading, only the cargo box 1 can be in the work position while the trailer performs other work, making the operation more versatile and the use more convenient. The trailer includes a trailer plate 5, steering wheels 6 and handles 8.

[0023] The trailer platform 5 is equipped with a lifting wheel assembly at its bottom, which includes a lifting wheel 61, a lifting frame 62, and a linkage control rod 63. One end of the lifting frame 62 is rotatably connected to the lifting wheel 61, and the other end of the lifting frame 62 is hinged to the linkage control rod 63. The trailer platform 5 is equipped with a mounting frame at its bottom, and the end of the mounting frame is hinged to the middle of the lifting frame 62. The linkage control rod 63 is horizontally set at the bottom of the trailer platform 5 and can slide axially. The linkage control rod 63 is controlled to slide axially and be fixed by electric or manual means at one end. At least one set of lifting frames 62 is hinged to the linkage control rod 63 to realize linkage control adjustment. By sliding the linkage control rod 63, the lifting frame 62 is controlled to swing around the end of the mounting frame, thereby adjusting the height of the lifting wheel 61. The lifting wheel 61 contacts the ground, thus changing the height of the trailer platform 5.

[0024] The handle 8 is connected to the steering wheel 6. Dragging the handle 8 can change the direction of the steering wheel 6. As needed, an electric power assist device can be installed on the steering wheel 6, equipped with a battery to reduce the labor intensity of transportation. The trailer plate 5 is equipped with a lifting bar 7 on the side near the handle 8. The lifting bar 7 is a mechanical or hydraulic jack used to lift one side of the truck bed 1, which facilitates the separation of the trailer from the truck bed 1, or assists in the tilting and dumping of the truck bed 1.

[0025] The truck bed 1 is located on the upper side of the trailer plate 5. The outer side of the truck bed 1 is provided with a support block 17 corresponding to the lifting rod 7. The top of the lifting rod 7 abuts against the support block 17 and can be separated. The lower side of the support block 17 is provided with a positioning groove that matches the top of the lifting rod 7. As needed, a quick-release connector, such as a bolt or pin, is provided between the support block 17 and the top of the lifting rod 7. The bolt or pin passes vertically through the support block 17. The top of the lifting rod 7 is provided with a corresponding threaded hole or pin hole. The support block 17 is provided with a strip hole corresponding to the bolt or pin to avoid movement interference when the lifting rod 7 is lifted. This is used to strengthen the connection strength between the support block 17 and the top of the lifting rod 7, improve the connection reliability, and prevent loosening during movement.

[0026] One side of the truck bed 1 is equipped with a load-bearing wheel 2 to support the load pressure of the truck bed 1. The other side of the truck bed 1 away from the load-bearing wheel 2 is equipped with a support rod 3. Two sets of support rods 3 can be set as needed, located on both sides of the truck bed 1 respectively. One side of the truck bed 1 is equipped with a rotary positioner 4 corresponding to the support rod 3. The rotary positioner 4 includes a turntable and a pin. The support rod 3 is fixedly connected to the turntable. The support rods 3 on both sides of the turntable are of different lengths. The turntable is rotatably connected to the truck bed 1. The turntable and the truck bed 1 are provided with pin holes. The pins fix the turntable. When the support rod 3 needs to be adjusted, the pins are pulled out, the support rod 3 is rotated, and then it is fixed by the pins. The pins can be equipped with anti-loosening pins or retaining rings, or bolts can be used instead of pins, and threaded holes can be used instead of pin holes. The bolts are connected to the turntable or the truck bed 1 to prevent the pins from falling off and being lost during movement.

[0027] like Figure 3 As shown, when the cargo bed 1 is not heavily loaded, or when the cargo bed 1 needs to be cleaned, the turntable is rotated to set one end of the long support rod 3 away from the load wheel 2, thereby lengthening the lever arm. This allows construction workers to use one end of the long support rod 3 as a handle to flip the cargo bed 1, dump the cargo, or clean the inside of the cargo bed 1.

[0028] The truck bed 1 has an sloping opening on the side near the load wheel 2. The truck bed 1 has a discharge port at the bottom of the sloping opening. A sealing plate 11 is provided on the discharge port. The truck bed 1 has a limiting device 12 on the side of the sealing plate 11. Both the sloping opening and the discharge port can be used for unloading. The unloading method can be freely selected according to the loaded material and weight.

[0029] Example 1: As Figure 4As shown, the trailer plate 5 has a wide unloading port. The upper surface of the trailer plate 5 abuts against the lower surface of the truck bed 1 and the sealing plate 11. The trailer plate 5 provides strong support for the sealing plate 11, preventing the building materials from bending the sealing plate 11. The truck bed 1 and the trailer plate 5 slide in contact. When unloading is required, the lifting rod 7 rises, slightly lifting one side of the truck bed 1. The support rod 3 is rotated, and the shorter end of the support rod 3 is used to press against the ground to temporarily support the truck bed 1. The quick-release connector on the lifting rod 7 is removed, and the linkage control rod 63 is activated to control the lifting frame 62 to swing. The lifting wheel 61 retracts, making it easy to separate the trailer from the truck bed 1. The trailer is switched to another truck bed 1 to continue towing and transporting. For the truck bed 1 loaded with materials, the sealing plate 11 is opened for unloading.

[0030] Example 2: Figure 5 As shown, the narrow unloading port has a notch on the trailer plate 5 that matches the unloading port, allowing for quick unloading without disassembling the trailer. The narrow sealing plate 11 is subjected to less force and is not easily deformed. After opening, unloading is completed through the narrow unloading port.
