Description
Technical Field
[0001] This utility model relates to the field of concrete transport vehicle technology, and in particular to a concrete transport vehicle with protective components. Background Technology
[0002] In the construction industry, concrete transport trucks play a crucial role in transporting mixed concrete from the batching plant to the construction site. Their efficient and stable transportation is essential for ensuring concrete quality and construction progress. Currently, concrete transport trucks equipped with protective components typically require the following technologies in practical applications:
[0003] 1. Reliable tank protection technology: It can effectively resist collisions and scratches that may occur during transportation, and prevent tank damage from affecting concrete transportation;
[0004] 2. Precise liquid level monitoring technology: Real-time and accurate monitoring of the concrete level inside the tank to avoid overflowing due to overfilling or underfilling due to insufficient liquid level, which would affect construction efficiency;
[0005] 3. Highly efficient cleaning and protection technology: After transportation, the tank and related components can be cleaned quickly and thoroughly to prevent concrete residue from corroding the equipment and to avoid residual concrete affecting the quality of the next transportation.
[0006] Currently, various equipment and methods are used to achieve the protective function of concrete transport vehicles. Some transport vehicles have baffles installed above the headlights in an attempt to block splashing concrete. The baffles need to be rotatable to ensure that the angle can be adjusted, and in order to prevent the baffles from rotating uncontrollably due to the accumulation of concrete, the installation of the baffles needs to be stable.
[0007] However, the above method has a prominent problem: during the concrete loading and unloading process, the direction and range of concrete spillage may vary depending on factors such as the operation method and the position of the tank. By adjusting the angle of the baffle, it can be better aligned with the direction in which concrete may spill. However, the existing devices usually lack a locking and limiting function when adjusting the baffle angle. The operator needs to support the baffle while installing and fixing it, which increases the complexity and difficulty of the operation and results in relatively low adjustment efficiency. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a concrete transport vehicle with protective components. It solves the problem that during the concrete loading and unloading process, the direction and range of concrete spillage may vary due to factors such as the operating method and the position of the tank. By adjusting the angle of the baffle, it can be better aligned with the direction where concrete may spill. However, existing devices usually lack a locking and limiting function when adjusting the baffle angle. Workers need to support the baffle while installing and fixing it, which increases the complexity and difficulty of the operation and results in relatively low adjustment efficiency.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A concrete transport vehicle with protective components includes a transport vehicle body. Inside the transport vehicle body is a shielding mechanism for protecting the vehicle lights. The shielding mechanism includes a round rod shaft and a vehicle light shield. The round rod shaft is rotatably connected inside the transport vehicle body, and the vehicle light shield is fixedly connected to the outer surface of the round rod shaft. Inside the transport vehicle body is an elastic mechanism for limiting the rotation of the round rod shaft. The elastic mechanism includes two rectangular spring plates and two limiting balls. The two rectangular spring plates are both disposed inside the transport vehicle body, and the two limiting balls are respectively fixedly connected inside the two rectangular spring plates. A set of spherical grooves is formed inside the round rod shaft, and the two limiting balls are adapted to the set of spherical grooves.
[0011] Preferably, an inclined guide plate is fixedly connected to the upper end of the headlight baffle, and a mounting bracket is fixedly connected to the outer surface of the transport vehicle body.
[0012] Preferably, the round rod shaft is rotatably connected inside the mounting frame, and the mounting frame is provided with bolt rods inside.
[0013] Preferably, the inner end of the round rod shaft away from the set of spherical slots is provided with a set of internal thread mounting slots, and the bolt rod is threadedly connected inside the set of internal thread mounting slots.
[0014] Preferably, the mounting bracket has two clamps inside, and the two clamps are hinged together.
[0015] Preferably, the outer surface of the mounting frame is provided with a flat shovel, which is disposed inside the two clamps.
[0016] Preferably, a round rod handle is fixedly connected inside the flat shovel, and a vehicle headlight support frame is fixedly connected to the outer surface of the transport vehicle body.
[0017] Preferably, the headlight body is fixedly connected to the outer surface of the headlight support frame, and the headlight body is located at the lower end of the headlight baffle.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. When loading and unloading concrete, to prevent the rear lights from being contaminated by concrete, the headlight baffle can be held and turned. The headlight baffle rotates around a round rod shaft inside the vehicle, causing the round rod shaft to rotate. During rotation, the limiting ball engages with the spherical groove inside the round rod shaft to limit the angle. As the headlight baffle rotates the shaft, the limiting ball is lifted along the surface of the spherical groove, pulling the rectangular spring plate to deform. When the next spherical groove is perpendicular to the limiting ball, the spring plate drives the ball to reset and engage in the groove, fixing the shaft angle and making the headlight baffle stable. This eliminates the need for workers to support and fix it at the same time, making the operation more convenient and efficient.
[0020] 2. When concrete adheres to the surface of the inclined guide plate, the worker can hold the round rod handle inside the flat shovel and use the sharp corner at the bottom of the flat shovel to scrape and clean the concrete from the surface of the inclined guide plate. One of the two sets of clamps on the mounting frame is located on the rectangular surface at the bottom of the round rod of the flat shovel. The round rod handle is placed on the upper end of the clamp to limit the vertical sliding space of the flat shovel and prevent the flat shovel from slipping when not in operation.

[0027] This application provides a concrete transport vehicle with protective components, effectively solving the problem that the direction and range of concrete spillage during the concrete loading and unloading process may vary due to factors such as operating methods and tank position. By adjusting the baffle angle, it can be better aligned with the direction of possible concrete spillage. However, existing devices typically lack a locking and limiting function when adjusting the baffle angle. Workers need to support the baffle while installing and fixing it, increasing the complexity and difficulty of the operation and resulting in relatively low adjustment efficiency. When loading and unloading materials on the transport vehicle, to prevent the rear lights from being contaminated by concrete, the headlight baffle can be held and turned by hand. The headlight baffle rotates around a round rod shaft inside the vehicle, causing the round rod shaft to rotate. During rotation, the limiting ball engages with the spherical groove inside the round rod shaft to limit the angle: the headlight baffle drives the shaft to rotate, and the limiting ball is lifted along the surface of the spherical groove, pulling the rectangular spring sheet to deform. When it rotates to the next spherical groove and is perpendicular to the limiting ball, the spring sheet drives the ball to reset and lock into the groove, fixing the shaft angle and making the headlight baffle stable without the need for staff to support and fix it at the same time.
[0028] Example
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that the direction and range of concrete spillage during concrete loading and unloading may vary due to factors such as operating method and tank position. By adjusting the baffle angle, it can be better aligned with the direction where concrete may spill. However, existing devices usually lack a locking and limiting function when adjusting the baffle angle. Workers need to support the baffle while installing and fixing it, which increases the complexity and difficulty of the operation and results in relatively low adjustment efficiency. The overall idea is as follows: a concrete transport vehicle with protective components. The system includes a transport vehicle body 11. Inside the transport vehicle body 11 is a shielding mechanism for protecting the vehicle lights. The shielding mechanism includes a round rod shaft 12 and a vehicle light shield 16. The round rod shaft 12 is rotatably connected inside the transport vehicle body 11, and the vehicle light shield 16 is fixedly connected to the outer surface of the round rod shaft 12. Inside the transport vehicle body 11 is an elastic mechanism for limiting the rotation of the round rod shaft 12. The elastic mechanism includes two rectangular spring plates 13 and two limiting balls 14. The two rectangular spring plates 13 are both located inside the transport vehicle body 11, and the two limiting balls 14 are respectively fixedly connected to the two rectangular spring plates 13. The cylindrical shaft 12 has a set of spherical grooves 15 inside, and two limiting balls 14 are adapted to the set of spherical grooves 15. The rotatable cylindrical shaft 12 shields and protects the rear lights of the transport vehicle, preventing concrete from adhering to the surface of the rear lights and causing contamination during loading and unloading operations. The headlight baffle 16 rotates within the transport vehicle body 11 around the cylindrical shaft 12. When adjusting the angle of the headlight baffle 16, the surface of the headlight baffle 16 is held and screwed. As the headlight baffle 16 rotates through the cylindrical shaft 12, it moves along the spherical surface of the spherical grooves 15. The lifting limit ball 14, when rising, pulls the rectangular spring plate 13 to deform. Due to the elasticity of the rectangular spring plate 13, when the rotation adjustment is made so that the next spherical slot 15 is perpendicular to the limit ball 14, the rectangular spring plate 13 drives the limit ball 14 to reset and engage in the spherical slot 15, thereby limiting the angle of the round rod shaft 12. Through this engaging and limiting operation, the stability of the headlight baffle 16 can be ensured when adjusting and installing the headlight baffle 16, avoiding the need for the staff to support the headlight baffle 16 while performing the fixing operation.
[0030] An inclined guide plate 17 is fixedly connected to the upper end of the headlight baffle 16. A mounting bracket 18 is fixedly connected to the outer surface of the transport vehicle body 11. A round rod shaft 12 is rotatably connected inside the mounting bracket 18. A bolt rod 19 is provided inside the mounting bracket 18. A set of internal threaded mounting grooves 21 is opened at the end of the round rod shaft 12 away from a set of spherical slots 15. The bolt rod 19 is threaded into the set of internal threaded mounting grooves 21. Two clamps 22 are provided inside the mounting bracket 18. The two clamps 22 are hinged together. A flat shovel 23 is provided on the outer surface of the mounting bracket 18. The flat shovel 23 is located inside the two clamps 22. A round rod handle 24 is fixedly connected inside the flat shovel 23. An inclined guide plate 17 is installed at the upper end of the headlight baffle 16. The inclined guide plate 17 can provide inclined guidance when concrete accumulates, causing it to fall to one end and avoid accumulation. The internal threaded mounting grooves 21 opened inside the round rod shaft 12 are used for Tighten and fix the bolt rod 19. The mounting bracket 18 has a through groove through which the bolt rod 19 can pass. Tighten the bolt rod 19 through the mounting bracket 18 into the internal thread mounting groove 21. At this time, the bolt rod 19 is attached to the surface of the mounting bracket 18. The position of the round rod shaft 12 is fixed in sequence. The flat shovel 23 is fixed on the surface of the mounting bracket 18 by two clamps 22. The lower end of the flat shovel 23 is pointed. The concrete adhering to the surface of the inclined guide plate 17 can be scraped off by the lower end of the flat shovel 23. The round rod handle 24 installed in the flat shovel 23 can provide a larger gripping area for the workers. The surface of the mounting bracket 18 is provided with two sets of clamps 22 (the two clamps 22 are fixed by tightening the screw). One set of clamps 22 is located on the rectangular surface of the bottom of the round rod when the flat shovel 23 is placed. The round rod handle 24 can be placed on the upper end of the clamp 22 to limit the vertical sliding space of the flat shovel 23 and prevent the flat shovel 23 from slipping.
[0031] A headlight support frame 25 is fixedly connected to the outer surface of the transport vehicle body 11, and a headlight body 26 is fixedly connected to the outer surface of the headlight support frame 25. The headlight body 26 is located at the lower end of the headlight baffle 16. The headlight body 26 installed at the rear end of the transport vehicle body 11 is used to emit light when braking or turning to remind following vehicles. The headlight support frame 25 provides installation space for the headlight body 26.
[0032] To address the problems existing in the prior art, this utility model provides a concrete transport truck with protective components. When loading and unloading concrete, to prevent the rear lights from being contaminated by concrete, the headlight baffle 16 can be held and turned. The headlight baffle 16 rotates within the vehicle body around the round rod shaft 12, causing the round rod shaft 12 to rotate. During rotation, the limiting ball 14 engages with the spherical groove 15 inside the round rod shaft 12 to limit the angle. As the headlight baffle 16 drives the shaft to rotate, the limiting ball 14 is lifted along the surface of the spherical groove 15, causing the rectangular spring sheet 13 to deform. When the next spherical groove 15 is perpendicular to the limiting ball 14, the spring sheet causes the ball to reset and engage with the groove, fixing the shaft angle and ensuring that the headlight baffle 16 is stably placed without the need for workers to support and fix it.

[0035] Rectangular spring sheet 13: When spring steel is subjected to stress and deformation, the dislocations inside the crystal will move. When an external force is applied to the rectangular spring sheet 13, the dislocations begin to slip, and the crystal structure gradually changes to adapt to the external force. However, due to the presence of alloying elements, they will hinder the movement of dislocations, so that the dislocations cannot move indefinitely. When the external force is removed, the dislocations will return to their original relatively stable positions under the hindrance of the alloying elements, so that the spring sheet returns to its initial shape and exhibits elasticity.
[0036] Limiting ball 14: Fixed inside the rectangular spring sheet 13, it is adapted to the spherical groove 15 of the round rod shaft 12. When rotating, it is lifted along the surface of the groove, causing the spring sheet to deform. When at the appropriate angle, it is reset and locked into the groove under the action of the spring sheet, limiting the rotation angle of the round rod shaft 12 and ensuring the stability of the position of the headlight baffle 16. It works in conjunction with the rectangular spring sheet 13 and the spherical groove 15 to precisely limit the position, providing angular positioning guarantee for headlight protection.
[0037] Spherical groove 15: Inside the round rod shaft 12, its shape matches the limiting ball 14. During rotation, it provides a movement track for the limiting ball 14, guiding its movement. It works with the limiting ball 14 to position the rotation angle of the round rod shaft 12, thus determining the protection angle of the headlight baffle 16. Together with the limiting ball 14 and the rectangular spring plate 13, it forms an angle limiting system to ensure accurate and stable positioning of the headlight baffle 16.
[0038] Headlight baffle 16: Fixed to the outer surface of the round rod shaft 12, it rotates within the vehicle body with the round rod shaft as its axis, shielding and protecting the rear headlights and preventing contamination during concrete loading and unloading; workers can screw its surface to rotate the round rod shaft 12 to adjust the angle to adapt to concrete spillage, and the inclined guide plate 17 at the upper end assists in preventing accumulation; it works with the round rod shaft 12 and the inclined guide plate 17 to provide protection and prevent accumulation, and together with the rectangular spring plate 13, it ensures stable protection after the angle is adjusted;

[0042] Internal thread mounting groove 21: Inside the round rod shaft 12, it matches the external thread of the bolt rod 19, providing an installation position. The round rod shaft 12 is fixed in the mounting bracket 18 by threaded connection, ensuring its stable position during operation and ensuring the normal operation of the vehicle light baffle 16. It works together with the bolt rod 19 and the mounting bracket 18 to fix the round rod shaft 12, and is an important connection part for stabilizing the protective structure.
[0043] Clamps 22: Two clamps are hinged together in the mounting frame 18. One set fixes the flat shovel 23 to prevent it from falling off, and the other set is located at the rectangular surface of the bottom of the round rod of the flat shovel 23 and cooperates with the round rod handle 24 to limit the vertical sliding space of the flat shovel 23.

[0046] The headlight support bracket 25 is fixed to the outer surface of the transport vehicle body 11, providing a stable installation space for the headlight body 26, making it securely located at the rear of the vehicle, ensuring that it does not shift during driving, and ensuring that the lighting warning function is normal; it works in conjunction with the transport vehicle body 11 and the headlight body 26 to achieve reliable installation, ensure the operation of the vehicle lighting warning system, and improve driving safety;
[0047] The headlight body 26 is fixed to the outer surface of the headlight support frame 25 and located at the lower end of the headlight baffle 16. It illuminates when the vehicle brakes or turns to remind the following vehicle and ensure driving safety. Its normal operation depends on the protection of the headlight baffle 16. It is securely installed in conjunction with the headlight support frame 25 and, in conjunction with the headlight baffle 16, performs its lighting warning function normally under protection to ensure driving safety.
[0048] Working principle:
[0049] The first step involves the transport vehicle body 11 serving as a concrete transport carrier, connecting the mixing plant production with the construction site to ensure the complete and timely delivery of concrete and guarantee the construction progress. A mixing tank is installed at its upper end, and the mixing tank is rotated through the chassis power transmission. The blades inside the tank mix the concrete to prevent segregation during transportation and ensure quality. The headlight support frame 25 is fixedly connected to the outer surface of the transport vehicle body 11, providing installation space for the headlight body 26, so that the headlight body 26 is stably installed at the rear end of the transport vehicle body 11. The headlight body 26 installed at the rear end of the transport vehicle body 11 emits light when the vehicle brakes, turns, or performs other operations, thereby alerting vehicles behind and ensuring driving safety.
[0050] In the second step, when the concrete truck is loading and unloading, the inclined guide plate 17 and the headlight baffle 16 can shield and protect the headlight body 26. To prevent concrete from adhering and contaminating the headlight, the headlight baffle 16 is twisted by holding its surface. The headlight baffle 16 rotates inside the truck body 11 around the round rod shaft 12, which is rotatably connected inside the truck body 11 (specifically through the mounting bracket 18). The headlight baffle 16 is fixedly connected to the outer surface of the round rod shaft 12, thereby driving the round rod shaft. During the rotation of the round rod shaft 12, the limiting ball 14 and a set of spherical grooves 15 inside the round rod shaft 12 cooperate to limit the angle. When the headlight baffle 16 drives the round rod shaft 12 to rotate, the limiting ball 14 will be lifted along the spherical surface of the spherical grooves 15. At this time, the limiting ball 14 pulls the rectangular spring plate 13 connected to it to deform. Since the rectangular spring plate 13 has its own elasticity, when the rotation is adjusted to the next spherical groove 15 being perpendicular to the limiting ball 14, the rectangular spring plate 13... The limiting ball 14 is reset and engaged in the spherical groove 15, thereby fixing the angle of the round rod shaft 12 and ensuring the stable placement of the headlight baffle 16 without the need for staff to support and fix it. The inclined guide plate 17 fixedly connected to the upper end of the headlight baffle 16 plays a role in preventing concrete from accidentally accumulating on the headlight baffle 16. Due to its inclined design, the concrete will slide off the surface of the inclined guide plate 17 to one end, preventing accumulation on the headlight baffle 16. The mounting bracket 18 is fixed with a flat shovel 23 by two clamps 22. The lower end of the flat shovel 23 is pointed. When concrete adheres to the surface of the inclined guide plate 17, the worker can hold the round rod handle 24 inside the flat shovel 23 and use the pointed end of the flat shovel 23 to scrape and clean the concrete on the surface of the inclined guide plate 17. There are two sets of clamps 22 on the mounting frame 18 (fixed by screwing screws). One set is located on the rectangular surface at the bottom of the round rod of the flat shovel 23. The round rod handle 24 is placed on the upper end of the clamp 22 to limit the vertical sliding space of the flat shovel 23 and prevent the flat shovel 23 from slipping when not in operation.
[0051] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
