Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a splash-proof mechanism for a concrete pump truck. Background Art

[0002] In construction, concrete pump trucks are commonly used equipment for transporting concrete to designated locations. Concrete has a certain fluidity and viscosity. During the pumping process, it is ejected at high speed from the discharge port at the end of the pump truck's boom. Due to this concrete output method, during the pouring process, the concrete at the discharge port is prone to splashing around. When concrete splashes, it will pollute the surrounding construction equipment, affecting its normal operation and service life. At the same time, the splashed concrete will also contaminate building materials, requiring additional cleaning work, which increases the burden on staff. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides an anti-splash mechanism for a concrete pump truck, which solves the problem that during the pouring process, concrete from the discharge port is easily splashed around. When concrete splashes, it will pollute the surrounding construction equipment, affecting its normal operation and service life. At the same time, the splashed concrete will also contaminate building materials, requiring additional cleaning work and increasing the burden on staff.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete pump truck anti-splash mechanism, comprising a protective shell, the inner walls on both sides of the protective shell are respectively fixedly connected to a plurality of lower connecting blocks, one end of the lower connecting block is rotatably connected to a buffer rod 1, the inner wall of the buffer rod 1 is slidably connected to a buffer rod 2, and the end of the buffer rod 2 is rotatably connected to an upper connecting block, the buffer rod 1 and the buffer rod 2 are hollow and have an inclined design, and the opposite sides of the inner walls of the buffer rod 1 and the buffer rod 2 are respectively fixedly connected to two limit rods, and the two limit rods are outer-mounted with a buffer spring, the inner walls on both sides of the protective shell are located above the lower connecting block and are respectively fixedly connected to a plurality of fixed shafts, and a buffer plate is rotatably connected between the corresponding two fixed shafts, the number of the buffer plates is two, the directions of the two buffer plates are opposite and both are of an inclined design, and one side of the plurality of upper connecting blocks is respectively connected to one side of the buffer plate.

[0005] As a further solution of the present invention: two fixing plates are fixed symmetrically about the center of the protective shell above, and a fixing screw is provided on one side of the fixing plate. The fixing screw passes through the fixing plate and is threadedly connected to the fixing plate.

[0006] As a further solution of the present invention: one end of the fixing screw is fixedly connected to a handle, and the end of the fixing screw away from the handle is rotatably connected to a fixing block, and there are two fixing blocks, which are in opposite directions.

[0007] As a further solution of the present invention: two sliding blocks are fixedly connected to the lower side of the fixed block, and the sliding blocks are designed in a T shape.

[0008] As a further solution of the present invention: two groups of sliding grooves are opened above the protective shell, and the slider slides in the sliding grooves.

[0009] As a further solution of the present invention: a discharge pipe is provided above the protective shell between the two fixed blocks, and the position of the discharge pipe corresponds to the position of the two buffer plates.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The anti-splash mechanism of the concrete pump truck is provided with a buffer plate, an upper connecting block, a buffer rod 1, a buffer rod 2, a buffer spring and a lower connecting block. During the unloading process, the concrete enters the protective shell through the discharge pipe of the pump truck and impacts the two buffer plates. After the two buffer plates are impacted, they rotate in the protective shell through the corresponding fixed shafts, and at the same time drive the upper connecting block to rotate at the end of the buffer rod 2. The buffer rod 2 and the buffer rod 1 adjust the angle of the buffer plate through the upper connecting block. At the same time, the buffer rod 2 slides on the inner wall of the buffer rod 1 to squeeze the buffer spring, and the impact force is transmitted to the buffer spring by squeezing the buffer spring. The buffer spring absorbs the impact force of the concrete unloading. In this way, the impact force of the concrete during unloading is slowed down. At the same time, the protective shell prevents the concrete from splashing during unloading, thereby avoiding pollution to surrounding equipment and materials.

[0012] 2. The anti-splash mechanism of the concrete pump truck is equipped with a fixed plate, a fixed screw, a fixed block, a chute and a slider. When unloading, the discharge pipe of the pump truck is placed between the two fixed blocks, and the two fixed screws are driven to rotate by two handles. The fixed screws rotate in the center of the fixed plate. Since the fixed screws and the fixed plate are connected by screws, the rotation of the fixed screw drives the fixed block to slide in the chute through the slider. The two fixed blocks approach each other to clamp the discharge pipe of the pump truck, thereby fixing the protective shell to the outer wall of the discharge pipe. This is not only convenient to operate, but also ensures the firmness of the connection and reduces the risk of the protective shell falling off the outer wall of the discharge pipe.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, the utility model provides a technical solution: a concrete pump truck anti-splash mechanism, comprising a protective shell 1, which is provided with the protective shell 1, and is sleeved on the outside of the discharge pipe 16 of the pump truck, so as to adapt to splashing conditions in different directions, provide all-round protection, and avoid concrete splashing. The inner walls on both sides of the protective shell 1 are respectively fixedly connected with a plurality of lower connecting blocks 2, one end of the lower connecting block 2 is rotatably connected with a buffer rod 1 3, the inner wall of the buffer rod 1 3 is slidably connected with a buffer rod 2 4, and the end of the buffer rod 2 4 is rotatably connected with an upper connecting block 5, the buffer rod 1 3 and the buffer rod 2 4 are hollow and of an inclined design, and two limiting rods 6 are respectively fixedly connected on the opposite sides of the inner walls of the buffer rod 1 3 and the buffer rod 2 4. Because the limiting rod 6 is provided, when the buffer spring 7 is compressed, the limiting rod 6 avoids the buffer spring 7 from flipping and deflecting.

[0020] The two limit rods 6 are outer-connected with buffer springs 7. Due to the provision of buffer springs 7, when concrete impacts the buffer plate 9, the buffer springs 7 are compressed and absorb part of the energy, thereby reducing the energy of the splash and preventing the concrete from splashing around at a greater speed and force. The inner walls on both sides of the protective shell 1 are located above the lower connecting block 2 and are fixedly connected with a plurality of fixed shafts 8. A buffer plate 9 is rotatably connected between the two corresponding fixed shafts 8. There are two buffer plates 9, and the directions of the two buffer plates 9 are relative and both are inclined. Due to the provision of buffer plates 9, during the unloading process, the two buffer plates 9 are impacted by the concrete and rotate between the inner wall of the protective shell 1 and the two corresponding fixed shafts 8. During the rotation, the upper connecting block 5 is driven to rotate at the end of the buffer rod 3, squeezing the buffer rod 3 and transmitting the impact force through the buffer rod 3 to the buffer spring 7, thereby alleviating the impact force generated when the concrete is unloaded. One side of the plurality of upper connecting blocks 5 is respectively connected to one side of the buffer plate 9;

[0021] Two fixing plates 10 are fixed symmetrically about the center of the protective shell 1 above the fixing plate 1. A fixing screw 11 is provided on one side of the fixing plate 10. The fixing screw 11 passes through the fixing plate 10 and is threadedly connected to the fixing plate 10. One end of the fixing screw 11 is fixedly connected to a handle 12. The end of the fixing screw 11 away from the handle 12 is rotatably connected to a fixing block 13. There are two fixing blocks 13. The directions of the two fixing blocks 13 are opposite. Two sliders 14 are fixedly connected to the bottom of the fixing block 13. The slider 14 is T-shaped. Two sets of slide grooves 15 are opened on the top of the protective shell 1. The slider 14 slides in the slide groove 15. Through the slider 14 and the slide groove 15, the two fixed blocks 13 drive the two opposite sliders 14 to slide in the slide groove 15 when approaching each other, thereby improving the stability of the fixed blocks 13 during the sliding and clamping processes. A discharge pipe 16 is provided above the protective shell 1 between the two fixed blocks 13. Through the cooperation between the fixed screws 11 and the fixed blocks 13, the two fixed screws 11 rotate and drive the two fixed blocks 13 to approach each other to clamp the discharge pipe 16 of the pump truck, thereby ensuring the stability of the connection between the discharge pipe 16 and the protective shell 1 and reducing the risk of the protective shell 1 falling off accidentally. The position of the discharge pipe 16 corresponds to the position of the two buffer plates 9.

[0022] The working principle of the present utility model is as follows: when the mechanism is in use, the handle 12 drives the fixed screw 11 to rotate, and the rotation of the fixed screw 11 cooperates with the fixed plate 10 to drive the fixed block 13 to slide in the slide groove 15 above the protective shell 1 through the slider 14, and the two fixed blocks 13 slide close to each other to clamp the discharge pipe 16 of the pump truck, and fix the protective shell 1 to the outer wall of the discharge pipe 16 of the pump truck. When the pump truck is unloading, concrete is ejected at high speed through the discharge pipe 16 to impact the two buffer plates 9. After the buffer plate 9 is impacted, it rotates between the corresponding two fixed shafts 8. During the rotation, the upper connecting block 5 drives the buffer rod 2 4 to slide on the inner wall of the buffer rod 1 3 to squeeze the buffer spring 7. The buffer spring 7 absorbs the impact force generated by the falling concrete through compression, so that the two buffer plates 9 buffer the speed of the concrete to prevent concrete from splashing, and the mechanism is used.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
