Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-tipping vehicle technology, specifically a self-tipping vehicle that facilitates unloading. Background Technology
[0002] In logistics, mining, and construction, self-tipping trucks, as a type of transport equipment that automatically unloads materials by tilting the vehicle, are widely used in the transfer of bulk materials (such as coal, sand, and ore) due to their high unloading capacity. Currently, self-tipping trucks on the market typically rely on flaps on both sides of the vehicle body in conjunction with pneumatic tilting cylinders to achieve unloading. Specifically, the pneumatic tilting cylinders extend and push the flaps to rotate around the hinge point, tilting the vehicle body and dumping the internal materials into a designated area. This process significantly reduces manual unloading time and improves operational efficiency.
[0003] However, when existing self-tipping trucks unload from one side, as the tilting angle of the tipper increases, the vehicle's center of gravity shifts drastically towards the unloading side, causing an imbalance in the overall force distribution of the vehicle. If the transported material has a high density, a large load, or the work site has poor surface flatness, it can easily lead to excessive tilting or even rollover accidents, causing not only equipment damage and material loss but also potentially posing a serious threat to the personal safety of on-site operators. Therefore, a self-tipping truck that facilitates unloading is proposed to address the aforementioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a self-tipping vehicle that facilitates unloading, thereby solving the problems mentioned in the background section.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a self-tipping vehicle for easy unloading, comprising a vehicle body, a stabilizing mechanism provided at the bottom of the vehicle body, the stabilizing mechanism comprising a fixing frame and a support plate, the fixing frame being installed at the bottom of the vehicle body, and two support plates being symmetrically arranged at the bottom of the fixing frame.
[0006] Preferably, a guide rail is installed at the bottom of the vehicle body, a linear motor is installed on the guide rail, a connecting block is connected to the bottom of the linear motor, and the bottom of the connecting block passes through the top of the fixing frame and is hinged to the support plate.
[0007] Preferably, a guide rod is provided on the inner side of the fixing frame, and sliding grooves are provided on both sides of the support plate, with the guide rod slidably connected to the inner wall of the sliding groove.
[0008] Preferably, the top of the fixing frame is provided with a positioning hole, the two sides of the connecting block are connected with positioning plates, the side of the linear motor is connected with a mounting plate, the bottom of the mounting plate is provided with an electromagnet, the positioning hole is provided with a positioning rod, and the positioning rod is magnetically connected to the electromagnet.
[0009] Preferably, the top of the fixing plate is provided with a slide rail, and the bottom of the positioning plate is provided with a ball bearing, which is slidably connected to the inner wall of the slide rail.
[0010] Preferably, the support plate is provided with a support mechanism, the support mechanism including a frame, the frame being installed at the bottom of the support plate, an electric push rod being installed on the inner wall of the frame, the output end of the electric push rod being fixedly connected to a push plate, and a pointed cone being provided on the push plate.
[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0012] 1. This self-tipping truck, which facilitates unloading, uses symmetrically arranged double support plates. The support state of one side support plate can be flexibly adjusted according to the unloading direction. Before unloading, the corresponding side support plate is lowered to the ground, while the other side support plate is kept in the retracted state to guide the center of gravity of the vehicle to shift towards the non-unloading side. This allows the two support plates to play a supporting and counterweighting role, effectively reducing the risk of tipping over due to heavy material loads and uneven ground, thereby ensuring the safety of equipment, materials, and operators.
[0013] 2. This self-tipping vehicle, which facilitates unloading, features an integrated support mechanism at the bottom of the support plate that further optimizes stability. When the support plate contacts the ground, an electric push rod can push the push plate with a pointed cone into the ground, making it particularly suitable for muddy and soft environments such as mines and construction sites, preventing the support plate from slipping or sinking. Furthermore, the support mechanism adopts a frame-like storage design, allowing the pointed cone and electric push rod to retract into the frame when not in use. With the help of a sealing ring, this design not only prevents external impurities from damaging the components but also does not affect the normal operation of the self-tipping vehicle.

[0023] 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.
[0024] Please see Figure 1-8 One embodiment of this utility model is: a self-tipping vehicle for easy unloading, including a vehicle body 1, a bogie 4 at the bottom of the vehicle body 1, a movable wheel on the bogie 4, flip plates on both sides of the vehicle body 1, a pneumatic tilting cylinder installed on the vehicle body 1, the pneumatic tilting cylinder being connected to the flip plate, the pneumatic tilting cylinder being used to drive the flip plate to tilt, thereby unloading the material inside the vehicle body 1, and a stabilizing mechanism 2 being provided at the bottom of the vehicle body 1.
[0025] The stabilizing mechanism 2 includes a fixed frame 21 and support plates 25. The fixed frame 21 is installed at the bottom of the vehicle body 1. There are two support plates 25, which are symmetrically arranged at the bottom of the fixed frame 21. A guide rail 22 is installed at the bottom of the vehicle body 1. Two linear motors 23 are installed on the guide rail 22. The bottom of the linear motors 23 is connected to a connecting block 24. The bottom of the connecting block 24 passes through the top of the fixed frame 21 and is hinged to the support plate 22. By setting two linear motors 23 on one guide rail 22, the two support plates 25 can be moved individually. A guide rod 26 is provided on the inner side of the fixed frame 21. Slide grooves are opened on both sides of the support plate 25. The guide rod 26 is slidably connected to the inner wall of the slide groove. By setting the guide rod 26 and the slide groove, when the linear motor 23 moves one side of the support plate 25 horizontally, the other side of the support plate 25 moves downward, thereby stabilizing the support plate 25. Ground contact improves the stability of the vehicle body 1 during unloading. The top of the fixed frame 21 is provided with a positioning hole 27. Positioning plates 28 are connected to both sides of the connecting block 24. The side of the linear motor 23 is connected with a mounting plate 29. An electromagnet 210 is provided at the bottom of the mounting plate 29. A positioning rod 211 is provided inside the positioning hole 27, and the positioning rod 211 passes through the positioning plate 28 and is magnetically connected to the electromagnet 210. By setting the positioning hole 27, positioning plate 28, and positioning rod 211, the support plate 25 can be fixed, preventing the support plate 25 from falling due to gravity during the movement of the vehicle body 1. The top of the fixed plate 21 is provided with a slide rail, and the bottom of the positioning plate 28 is provided with a ball bearing. The ball bearing is slidably connected to the inner wall of the slide rail. By setting the slide rail and the ball bearing, the friction force when the connecting block 24 moves can be reduced, thereby improving the stability when the linear motor 23 drives one end of the support plate 25 to move.
[0026] Working principle: When the vehicle body 1 needs to unload, the pneumatic tilting cylinder drives the flip plate on one side to flip and unload. Before this, the electromagnet 210 on the linear motor 23 on the side to be unloaded is de-energized, so that the positioning rod 211 falls completely into the positioning hole 27 under the action of gravity, releasing the restriction on the connecting block 24. By starting the corresponding linear motor 23, the connecting block 24 is moved, so that the corresponding support plate 25 contacts the ground under the action of the guide rod 26 and the slide, thereby supporting the unloading side and improving the stability during unloading. At the same time, the support plate on the other side does not move, so that the center of gravity of the vehicle body 1 moves in the direction of the unloading side, thereby further improving the stability during unloading. After the operation is completed, the pneumatic tilting cylinder is started again to open the side plate for unloading.
[0027] After unloading, the pneumatic tilting cylinder drives the flap to rotate and retract the flap. After retraction, the linear motor 23 on the support plate 25 is started to retract the support plate 25. After retraction, the electromagnet 210 is energized, and the electromagnet 210 will attract the positioning rod 211, so that the positioning rod 211 passes through the positioning plate 28 and connects to the bottom of the electromagnet 210, thereby locking the support plate 25 for easy use next time.
[0028] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, a support mechanism 3 is provided on the support plate 25. The support mechanism 3 includes a frame 31, which is installed at the bottom of the support plate 25. An electric push rod 32 is installed on the inner wall of the frame 31. A push plate 33 is fixedly connected to the output end of the electric push rod 32. A pointed cone 34 is provided on the push plate 33. A sealing ring is fitted on the upper part of the electric push rod 33, and the electric push rod 33 is slidably connected to the inner wall of the frame 31 through the sealing ring. The sealing ring is provided to protect the electric push rod 32 when it is not in use.
[0029] Working principle: When the support plate 25 on one side contacts the ground, the electric push rod 32 is activated, which pushes the push plate 33 to move, causing the pointed cone at the bottom of the push plate 33 to penetrate the ground, thereby further improving the stability of the support plate 25 when it is providing support.
[0030] When the support plate 25 is retracted, the electric push rod 32 drives the push plate 33 to retract, thereby retracting the cone 33 into the frame 31. The sealing ring between the push plate 33 and the frame 31 protects the electric push rod 32 inside the frame 31, preventing damage to the electric push rod 32 caused by external factors.
[0031] This utility model provides a self-tipping vehicle for easy unloading. There are many methods and approaches to implement this technical solution; the above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
