Description

Technical Field

[0001] This utility model relates to the field of unloading equipment technology, specifically to a highly stable unloading equipment for construction projects. Background Technology

[0002] Construction engineering refers to the general term for all kinds of buildings and engineering facilities that provide the material and technical foundation for human life and production. It can be divided into three categories: building engineering, civil engineering, and electromechanical engineering. Building engineering mainly includes the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Civil engineering covers the construction of infrastructure such as roads, bridges, tunnels, and water conservancy and hydropower projects. Electromechanical engineering involves the installation and commissioning of various mechanical equipment, electrical equipment, and automated instruments. During the construction process, various raw materials and goods are required. After the raw materials and goods are transported to the designated location, unloading equipment with high stability is required to unload them in order to ensure unloading efficiency and safety.

[0003] A high-stability unloading device for construction projects, disclosed in patent application CN 215515900U, includes a bottom housing. A control panel is fixedly embedded in the front of the bottom housing. A through groove is formed on the upper surface of the bottom housing. An electromechanical box is connected to the left side of the bottom housing. A motor is connected to the inner wall of the electromechanical box. Two first bearings are fixedly embedded in the inner wall of the bottom housing. A threaded rod is connected to the inner wall of the two first bearings. The output end of the motor is connected to the left end of the threaded rod. This high-stability unloading device for construction projects uses a motor to rotate, driving the threaded rod to rotate. Two internally threaded sliders on the threaded rod move closer and further apart, thereby raising and lowering the carrier plate to transport materials from a truck. However, during the raising and lowering of the carrier plate, the conveyor belt lacks an adjustment component, making it impossible to adjust the tension of the conveyor belt. This may cause the conveyor belt to loosen, affecting the safety, stability, and efficiency of unloading. Utility Model Content

[0004] This invention provides a highly stable unloading device for construction projects, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a highly stable unloading device for construction projects, comprising:

[0007] Fixed base plate, wheels, and unloading conveyor belt;

[0008] The lifting assembly is symmetrically connected to both sides of the fixed base plate and is used to control the operating height of the unloading equipment;

[0009] A drive assembly, connected to the top surface of the fixed base plate, is used to provide driving force to the unloading equipment;

[0010] A guide assembly, connected to the side of the lifting assembly near the drive assembly, is used to keep the unloading conveyor belt taut to ensure efficient and stable unloading.

[0011] Through the above technical solution, during use, the height of the lifting component is controlled to match the height of the cargo box of the transport vehicle. Based on the height of the lifting component, the position of the guide component is controlled to keep the unloading conveyor belt taut. Then, the drive component is used to drive the unloading conveyor belt to start unloading.

[0012] Furthermore, the lifting assembly includes fixed vertical plates, which are symmetrically arranged on both sides of a fixed base plate. Lifting grooves are provided inside the two fixed vertical plates, and sliders are slidably connected inside the lifting grooves. Lifting frames are symmetrically connected to the top surfaces of the sliders, and support rollers are rotatably connected between the two lifting frames. A first telescopic cylinder is bolted to the center of the top surface of the fixed base plate, and the top of the first telescopic cylinder is connected to the bottom surface of the slider by bolts.

[0013] The above technical solution facilitates the control of the height of the support rollers in the lifting assembly, adapts to the height of the transport truck, and facilitates unloading.

[0014] Furthermore, a second rotating plate is rotatably sleeved at both ends of the driven unloading roller. The second rotating plate has symmetrical insertion holes inside. A support roller is rotatably mounted between the two second rotating plates. Baffles are provided on both sides of the two second rotating plates.

[0015] The above technical solution enables the second rotating plate to change with the height of the driven unloading roller, improving the structural stability of the device, providing a certain guiding effect for the goods, and ensuring safe unloading.

[0016] Furthermore, the drive assembly includes a fixed frame, which is symmetrically arranged on the top surface of the fixed base plate away from the first telescopic cylinder. An active unloading roller is rotatably connected between the two fixed frames. A drive motor is installed on the back of one of the fixed frames, and the output end of the drive motor is connected to the active unloading roller.

[0017] The above technical solution provides power for the operation of the unloading conveyor belt, enabling the unloading conveyor belt to operate.

[0018] Furthermore, both ends of the active unloading roller are rotatably fitted with first rotating plates, and the ends of the two first rotating plates away from the fixed frame are symmetrically provided with insertion rods, which are matched with insertion holes.

[0019] The above technical solution, combined with the second rotating plate, enhances the stability of the architecture.

[0020] Furthermore, the conductor assembly includes two guide frames, which are disposed on one side of the fixed vertical plate. Both guide frames have straight slots and tension rollers are rotatably connected inside the two straight slots. A second telescopic cylinder is installed on the side of the two guide frames that is far apart from each other, and the telescopic end of the second telescopic cylinder is rotatably connected to both ends of the tension roller.

[0021] Through the above technical solution, when the height of the driven unloading roller changes, the tension roller is used to keep the unloading conveyor belt taut, ensuring unloading efficiency and stability.

[0022] The above-described solution of this utility model has at least the following beneficial effects:

[0023] By controlling the extension and retraction of the second telescopic cylinder, the tension roller is driven to slide along the straight groove, changing the position of the tension roller and pulling the unloading conveyor belt, so that it maintains a good transport state when the position of the driven unloading roller changes, which helps to ensure the stability, safety and efficiency of unloading.

[0024] By designing the first rotating plate, the insert rod, and the second rotating plate, the angles of the first rotating plate, the insert rod, and the second rotating plate change simultaneously when the height of the driven unloading roller changes. At the same time, the insert rod inserts into the second rotating plate, forming an automatically retractable reinforcement structure, which enhances the stability and strength of the device.

While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0032] like Figures 1 to 4 As shown, an embodiment of this utility model provides a highly stable unloading device for construction projects, comprising:

[0033] Fixed base plate 1, traveling wheels 2, unloading conveyor belt 10;

[0034] The lifting assembly is symmetrically connected to both sides of the fixed base plate 1 and is used to control the operating height of the unloading equipment;

[0035] The drive assembly, connected to the top surface of the fixed base plate 1, is used to provide driving force for the unloading equipment;

[0036] The guide assembly, connected to the lifting assembly on the side near the drive assembly, is used to keep the unloading conveyor belt 10 taut, ensuring efficient and stable unloading.

[0037] When in use, the device is equipped with an external controller to control the extension and retraction of the first telescopic cylinder 20, the second telescopic cylinder 16, and the drive motor 9, which drives the tension roller 18 to slide along the straight groove 17, changes the position of the tension roller 18, and pulls the unloading conveyor belt 10, so that it maintains a good transport state when the position of the driven unloading roller 19 changes.

[0038] The lifting assembly includes fixed vertical plates 3, which are symmetrically arranged on both sides of the fixed base plate 1. Lifting grooves 4 are opened inside the two fixed vertical plates 3. Sliding sliders 5 are slidably connected inside the lifting grooves 4. Lifting frames 6 are symmetrically connected to the top surface of the sliders 5. Support rollers 21 are rotatably connected between the two lifting frames 6. A first telescopic cylinder 20 is bolted to the middle of the top surface of the fixed base plate 1. The top of the first telescopic cylinder 20 is connected to the bottom surface of the slider 5 by bolts.

[0039] In this embodiment, the first telescopic cylinder 20 extends and retracts, causing the slider 5 to slide along the lifting groove 4, which in turn causes the height of the lifting frame 6 to change, thereby changing the position of the driven unloading roller 19.

[0040] The support roller 21 is rotatably fitted with a second rotating plate 13 at both ends. The second rotating plate 13 has symmetrical insertion holes inside. The support roller 21 is rotatably mounted between the two second rotating plates 13. Baffles 14 are provided on both sides of the two second rotating plates 13.

[0041] In this embodiment, when the unloading conveyor belt 10 is in operation, the unloading conveyor belt 10 moves along the support roller 21, and the support roller 21 supports the goods.

[0042] The drive assembly includes a fixed frame 7, which is symmetrically arranged on the top surface of the fixed base plate 1 away from the first telescopic cylinder 20. An active unloading roller 8 is rotatably connected between the two fixed frames 7. A drive motor 9 is installed on the back of one of the fixed frames 7, and the output end of the drive motor 9 is connected to the active unloading roller 8.

[0043] In this embodiment, when the drive motor 9 is running, the drive motor 9 drives the active unloading roller 8 to rotate, thereby driving the unloading conveyor belt 10 to operate.

[0044] Both ends of the active unloading roller 8 are fitted with first rotating plates 11. The ends of the two first rotating plates 11 away from the fixed frame 7 are symmetrically provided with insertion rods 12, and the insertion rods 12 are matched with the insertion holes.

[0045] In this embodiment, when the height of the driven unloading roller 19 changes, the angles of the first rotating plate 11, the insertion rod 12, and the second rotating plate 13 change simultaneously, and the insertion rod 12 is inserted into the second rotating plate 13 to form an automatically retractable reinforced structure.

[0046] The guiding assembly includes two guide frames 15, which are located on one side of the fixed vertical plate 3. Both guide frames 15 have straight slots 17, and tension rollers 18 are rotatably connected inside the two straight slots 17. A second telescopic cylinder 16 is installed on the side of the two guide frames 15 that is far apart from each other. The telescopic end of the second telescopic cylinder 16 is rotatably connected to both ends of the tension roller 18.

[0047] In this embodiment, when the second telescopic cylinder 16 extends or retracts, it drives the tension roller 18 to slide along the straight groove 17, changes the position of the tension roller 18, and pulls the unloading conveyor belt 10, so that when the position of the driven unloading roller 19 changes, the unloading conveyor belt 10 remains taut and maintains a stable transportation state.

[0048] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
