Specific implementation

[0026] The embodiment of the application will be described in detail below with the help of drawings and examples, so that the realization process of how to apply technical means to solve technical problems and achieve technical effects of the application can be fully understood and implemented.

[0027] As Figures 1-6 Indicated, the building engineering material transport vehicle provided by the embodiment includes a car frame 1 and a car hopper 2 fixedly installed on the car frame 1, a guide column 3 is fixedly installed on one side of the car frame 1 corresponding to the car hopper 2, an unloading door 4 is rotationally connected to one end of the car hopper 2 away from the guide column 3, a U-shaped push rod 5 is slidingly arranged on the guide column 3, one end of the U-shaped push rod 5 away from the guide column 3 extends to both sides of the car hopper 2, guide sleeves 18 are fixedly arranged on both sides of the car hopper 2, both ends of the U-shaped push rod 5 extend to the inner side of the sliding blocks 7 through the inside of the guide sleeves 18, and the guide column 3 and the guide sleeves 18 are used for guiding the sliding of the U-shaped push rod 5.

[0028] Sliding blocks 7 are slidingly arranged on both sides of the car hopper 2, a bolt 8 is fixedly installed on the sliding block 7, one side of the bolt 8 abuts against the side surface of the unloading door 4, the bolt 8 is used for limiting the unloading door 4, so that the unloading door 4 is attached to the slope of the car hopper 2, and material leakage is prevented, rollers 9 are rotationally arranged on the inner side of the sliding blocks 7, inclined planes 10 are arranged on both ends of the U-shaped push rod 5 close to the unloading door 4, the rollers 9 correspond to the inclined planes 10, the sliding of the rollers 9 on the inclined planes 10 increases the distance between the sliding blocks 7 and the side surface of the car hopper 2, the contact friction is changed into rolling friction, and the abrasion can be reduced.

[0029] Wherein, the U-shaped push rod 5 can slide on the guide column 3 and the guide sleeve 18, the slope 10 at the top end of the U-shaped push rod 5 is in contact with the roller 9 during the sliding process of the U-shaped push rod 5, the distance between the side surface of the roller 9 and the side surface of the hopper 2 increases when the roller 9 rolls, thereby making the sliders 7 on both sides away from the two sides of the hopper 2, the bolt 8 is away from the side surface of the discharge door 4, the discharge door 4 is released from the bolt after rotating and opening under the action of its own gravity and the pressure of the material, the material slides down immediately, which reduces the residue of the material without deliberately lifting the hopper 2, and the unloading is more time-saving and labor-saving.

[0030] Further, as shown in Figure 1 、 Figure 2 and Figure 4 , the push-pull handle 11 is fixedly installed on the frame 1, the hopper 2 is fixedly arranged on the side away from the push-pull handle 11, the wheel 12 is rotatably arranged on the frame 1 corresponding to the middle part of the hopper 2, and the support leg 13 is fixedly installed on the frame 1 corresponding to the guide column 3. The bottom ends of the wheel 12 and the support leg 13 are on the same horizontal plane, the push-pull handle 11 and the wheel 12 facilitate the staff to use the material carrier to move flexibly and quickly in the construction site, the wheel 12 can well share the weight of the hopper 2 and the material at the middle bottom side of the hopper 2, thereby improving the stability, and the support leg 13 can form a fixed support with the bottom side of the wheel 12, thereby facilitating the staff to load the material, and one person can operate.

[0031] Further, as shown in Figure 3 、 Figure 4 and Figure 5 , the reset spring 14 is sleeved on the guide column 3, one end of the reset spring 14 away from the frame 1 is fixedly connected to the U-shaped push rod 5, two positioning sleeves 15 distributed upward and downward are fixedly installed on the two sides of the hopper 2, the guide rod 16 is fixedly installed in the positioning sleeve 15, the guide rod 16 penetrates through the slider 7 and extends to the outside of the slider 7, the slider 7 is slidably arranged on the guide rod 16, the tension spring 17 is sleeved on the guide rod 16, one end of the tension spring 17 away from the hopper 2 is fixedly connected to the slider 7, and one end of the tension spring 17 close to the hopper 2 is fixedly connected to the guide rod 16; wherein, the guide column 3 and the reset spring 14 are used for making the U-shaped push rod 5 slide stably and reset quickly, which can ensure that the U-shaped push rod 5 can automatically return to the initial state after pushing the slider 7 to slide, and the slider 7 is reset through the guidance of the guide rod 16 under the action of the tension spring 17 after the U-shaped push rod 5 is reset. Further, the bolt 8 is reset, which is conducive to the recycling of the discharge door 4, and the reset spring 14 can also have a buffering effect, when the U-shaped push rod 5 is subjected to a relatively sudden impact force, the reset spring 14 can absorb part of the energy, which can protect other components connected with the U-shaped push rod 5 and the whole mechanical device, reduce the possibility of damage of the components due to strong impact, and prolong the service life of the material carrier.

[0032] Further, as shown in Figures 1-6As shown, the end of the pin 8 furthest from the slider 7 is slidably connected to a wedge-shaped stop 6 via an elastic telescopic rod. During the closing process of the unloading gate 4, the unloading gate 4 corresponds to the wedge-shaped stop 6. The wedge-shaped stop 6 makes it easier for the unloading gate 4 to insert into the pin 8 when closing. The presence of the wedge-shaped stop 6 allows the unloading gate 4 to automatically retract into the pin 8 by contacting the wedge-shaped stop 6 during the closing process, utilizing the inclined surface of the wedge-shaped stop 6 to generate a component force. The wedge-shaped stop 6 then extends out to limit the movement after the unloading gate 4 is fully closed. The elasticity and hardness of the elastic telescopic rod, as well as the contact area between the wedge-shaped stop 6 and the unloading gate 4, are selected according to the size of the engineering material transport vehicle and the material transport volume to ensure... Figure 3 When in the indicated orientation, the unloading gate 4 can be easily pushed in from right to left, but it will not automatically push out from left to right.

[0033] like Figures 1-6 As shown, the principle of the construction material transport vehicle provided in this embodiment is as follows:

[0034] During unloading, the U-shaped push rod 5 is pushed forward to slide on the guide post 3 and the guide sleeve 18. During the sliding process, the inclined surface 10 at the top of the U-shaped push rod 5 contacts the roller 9. When the roller 9 rolls, the distance between its side and the side of the truck bed 2 increases, thereby causing the sliders 7 on both sides to move away from the sides of the truck bed 2. The pin 8 then moves away from the side of the unloading gate 4. The guide post 3 and the return spring 14 are used to make the U-shaped push rod 5 slide smoothly and return quickly, ensuring that the U-shaped push rod 5 can automatically return to the initial state after pushing the slider 7 to slide. After the U-shaped push rod 5 returns to the reset, the slider 7 returns to the reset under the action of the tension spring 17 and the guide rod 16, thereby causing the pin 8 to return to the reset. After the unloading gate 4 is freed from the pin restraint, it rotates and opens under its own weight and the pressure of the material. During loading, the unloading gate 4 is pushed to fit against the wedge-shaped stop 6 on the pin 8. After the unloading gate 4 is fully closed, the wedge-shaped slider 6 extends to limit the movement.
