Description

Technical Field

[0001] The utility model relates to the field of grouting equipment, in particular to a spreading device used for semi-flexible road surface grouting construction. Background Art

[0002] In the construction of semi-flexible pavement, the asphalt mixture is first laid on the roadbed and rolled repeatedly for a long time using a roller to reduce the pores in the asphalt mixture. Then, a high-fluidity cement-based grouting material is manufactured using grouting equipment and output to flow on the surface and inside of the asphalt mixture, thereby filling the pores formed by the asphalt mixture and forming a composite pavement material that is both rigid and flexible.

[0003] The grouting equipment currently used is relatively large in size. For example, a Chinese patent with patent publication number CN217758194U discloses a semi-flexible pavement grouting equipment, which includes a box body, in which a feeding device, a water tank and a mixing drum are arranged. A mixing shaft is arranged in the mixing drum, and a mixing motor is arranged on the upper surface of the mixing drum. A scraping opening is opened in the thickness direction of the upper end wall of the mixing drum, and the scraping opening is opened in the circumferential direction of the upper end wall of the mixing drum. A plurality of connecting rods are arranged on the upper surface of the mixing drum, and an annular scraper plate is arranged in the scraping opening.

[0004] Because the grouting equipment is large in size and requires a large amount of raw materials, the grouting equipment is usually placed on the rear end of the flatbed of a semi-trailer. After the cement-based grouting material is made by mixing multiple materials in the mixing drum of the grouting equipment, the cement-based grouting material is transported from the lower end of the mixing drum along the grouting pipe to a certain location, and it takes a long time to completely output the cement-based grouting material. During the process of outputting the cement-based grouting material, the mixing of the materials is stopped. After the cement-based grouting material is completely output, it takes time to mix the multiple materials using the mixing drum, and the grouting process is stopped during the mixing of the materials. Therefore, when the grouting equipment is used for grouting, the material mixing and grouting are completely separated, which seriously affects the grouting efficiency and the construction of the semi-flexible pavement.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a spreading device for semi-flexible pavement grouting construction includes a grouting equipment body 1, a temporary storage barrel 2 and a spreading device 3. The grouting equipment body 1 includes a shell, a mixing drum located inside the shell, a water tank and a screw feeder. The mixing drum is located at the end of the shell, and a feeding port is provided at the lower end. A valve is provided on the feeding buckle, and a grouting pipe 11 is externally connected. The screw feeder and the water tank are both connected to the mixing drum. In addition, auxiliary materials are stacked inside the grouting equipment body 1. When the cement-based grouting material is manufactured by the mixing drum, the auxiliary materials and the main materials are put into the mixing drum. The end of the slurry delivery pipe 11 is arranged at the upper end of the temporary storage barrel 2, and a plurality of universal wheels 22 are arranged at the lower end of the temporary storage barrel 2, and a handle 21 is arranged on the outer side. Therefore, when the materials in the mixing drum are mixed evenly, the cement-based grouting material is transported to the temporary storage barrel 2 by adjusting the unobstructedness of the valve. Because the grouting equipment body 1 is placed on the flatbed of the semi-trailer, and the temporary storage barrel 2 is placed on the road surface, there is a height difference between the two, so the cement-based grouting material can flow into the temporary storage barrel 2. The setting of the temporary storage barrel 2 can temporarily store the cement-based grouting material, and provide support for the mixing drum operation and the overlapping of slurry spraying. Specifically , the flow rate of the cement-based grouting material output from the mixing drum can be controlled by a valve, so that a small amount of cement-based grouting material is stored in the temporary storage barrel 2, and the cement-based grouting material is spread. When the volume of the remaining cement-based grouting material in the mixing drum is less than or equal to the volume of the temporary storage barrel 2, the flow rate of the cement-based grouting material output from the mixing drum can be increased, and the cement-based grouting material can be completely input into the temporary storage barrel 2 in a short time. Then, when the cement-based grouting material is output and spread in the temporary storage barrel 2, the material is added to the mixing drum to manufacture the next batch of cement-based grouting materials, thereby improving the efficiency of preparing and spreading cement-based grouting materials.The spreading device 3 is arranged at the bottom of the temporary storage tube 2, and a plurality of screws are fixedly arranged on the bottom plate of the temporary storage tube 2. The spreading device 3 includes a spraying pipe 43, a rotating ring plate 41, a gear 42 and a supporting ring plate 44. A plurality of ear plates 45 are arranged on the outer side of the supporting ring plate 44. The ear plates 45 are sleeved on the screws, and nuts are threadedly sleeved on the lower ends of the screws. Therefore, the supporting ring plate 44 is detachably arranged below the temporary storage tube 2. The rotating ring plate 41 penetrates the supporting ring plate 44, and a gear ring 46 is arranged on the outer side thereof. Therefore, the rotating ring plate 41 can penetrate the supporting ring plate 44 through a bearing connection, or the gear ring 46 can be directly supported on the supporting ring plate 44. The spraying pipe 43 is arranged below the rotating ring plate 41, and can be rotated periodically with the rotating ring plate 41. Rotation, a motor is also provided on the side of the support ring plate 44, and the motor is connected to the temporary storage tube 2, and the connection method is the same as that of the support ring plate 44. The gear 42 is sleeved on the output shaft of the motor, and the ring gear 46 is meshed with the gear 42. Under the operation of the motor, the gear 42 can be controlled to rotate periodically in both positive and negative directions, thereby driving the rotating ring plate 41 to rotate periodically in both positive and negative directions, and changing the direction of the spraying pipe 43, so that the cement-based grouting material can be sprayed over a larger range without changing the position of the temporary storage tube 2, avoiding the need to continuously move the temporary storage tube 2 to increase the labor intensity of the workers. After the cement-based grouting material is poured in the area, the staff holds the handle 21 and pushes the temporary storage tube 2 to move, and the position of the temporary storage tube 2 can be adjusted to provide support for completing the pouring of the entire road surface. In order to control the smoothness of the spraying pipe 43, a valve is provided on the spraying pipe 43, and the spraying pipe 43 is connected to the temporary storage tube 2 through a hose.

[0028] When the rotating ring plate 41 is directly supported on the supporting ring plate 44 through the gear ring 46, the top of the rotating ring plate 41 needs to contact the bottom plate of the temporary storage tube 2. In order to reduce the friction between the rotating ring plate 41 and the temporary storage tube 2, a thrust bearing can be sleeved on the upper end of the rotating ring plate 41. At the same time, the outer diameter of the gear ring 46 is larger than the inner diameter of the supporting ring plate 44.

[0029] like Figure 6 As shown, in order to stably install the spray pipe 43 below the rotating ring plate 41 and disassemble it according to needs, a first clamping plate 47, a second clamping plate 5 and a fixed plate 51 are arranged below the rotating ring plate 41. The first clamping plate 47 and the second clamping plate 5 are symmetrically arranged, and the sides close to each other are arranged in an arc structure. The second clamping plate 5 is arranged on the side away from the first clamping plate 47. The adjusting screw 52 is threaded through the fixed plate 51. The fixed plate 51 and the first clamping plate 47 are fixedly connected to the rotating ring plate 41. When the spray pipe 43 needs to be disassembled, the staff rotates the adjusting screw 52 to control the second clamping plate 5 to move relative to the first clamping plate 47, so as to release the restriction of the spray pipe 43. When it is necessary to install it on the spray pipe 43, the above steps can be reversed.

[0030] like Figure 2As shown, in order to prevent the cement-based grouting material inside the temporary storage tube 2 from settling, a stirring shaft 23 can be set inside the temporary storage tube 2. A rotating wheel 24 is set at the upper end of the stirring shaft 23. The staff can rotate the rotating wheel 24 to drive the stirring shaft 23 to rotate, and the stirring blades are driven by the stirring shaft 23 to stir the cement-based grouting material to rotate.

[0031] Example 2

[0032] like Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, a spreading device for semi-flexible pavement grouting construction includes a grouting equipment body 1, a temporary storage barrel 2 and a spreading device 3. The grouting equipment body 1 includes a shell, a mixing drum located inside the shell, a water tank and a screw feeder. The mixing drum is located at the end of the shell, and a feeding port is provided at the lower end. A valve is provided on the feeding buckle, and a grouting pipe 11 is externally connected. The screw feeder and the water tank are both connected to the mixing drum. In addition, auxiliary materials are stacked inside the grouting equipment body 1. When the cement-based grouting material is manufactured by the mixing drum, the auxiliary materials and the main materials are put into the mixing drum. The end of the slurry delivery pipe 11 is arranged at the upper end of the temporary storage barrel 2, and a plurality of universal wheels 22 are arranged at the lower end of the temporary storage barrel 2, and a handle 21 is arranged on the outer side. Therefore, when the materials in the mixing drum are mixed evenly, the cement-based grouting material is transported to the temporary storage barrel 2 by adjusting the unobstructedness of the valve. Because the grouting equipment body 1 is placed on the flatbed of the semi-trailer, and the temporary storage barrel 2 is placed on the road surface, there is a height difference between the two, so the cement-based grouting material can flow into the temporary storage barrel 2. The setting of the temporary storage barrel 2 can temporarily store the cement-based grouting material, and provide support for the mixing drum operation and the overlapping of slurry spraying. Specifically , the flow rate of the cement-based grouting material output from the mixing drum can be controlled by a valve, so that a small amount of cement-based grouting material is stored in the temporary storage barrel 2, and the cement-based grouting material is spread. When the volume of the remaining cement-based grouting material in the mixing drum is less than or equal to the volume of the temporary storage barrel 2, the flow rate of the cement-based grouting material output from the mixing drum can be increased, and the cement-based grouting material can be completely input into the temporary storage barrel 2 in a short time. Then, when the cement-based grouting material is output and spread in the temporary storage barrel 2, the material is added to the mixing drum to manufacture the next batch of cement-based grouting materials, thereby improving the efficiency of preparing and spreading cement-based grouting materials. The spreading device 3 is arranged at the bottom of the temporary storage tube 2, and a plurality of screws are fixedly arranged on the bottom plate of the temporary storage tube 2. The spreading device 3 includes a delivery pump 61, a delivery pipe 62, a gear ring 46, a gear 42 and a support ring plate 44. A plurality of ear plates 45 are arranged on the outer side of the support ring plate 44. The ear plates 45 are sleeved on the screws, and a nut is threadedly sleeved on the lower end of the screws, so that the support ring plate 44 is detachably arranged below the temporary storage tube 2. The delivery pump 61 is arranged through the support ring plate 44. The gear ring 46 is arranged on the delivery pump 61 and meshes with the gear 42. The gear 42 is sleeved on the output shaft of the motor. The two ends of the delivery pipe 62 are respectively connected to the temporary storage tube 2 and the delivery pump 61, and a valve is arranged. Under the action of the delivery pump 61, the cement-based grouting material can be controlled to be output at a high speed, which provides support for further expanding the spreading range of the cement-based grouting material without moving the temporary storage tube 2, and further reduces the labor intensity of the staff.

[0033] like Figure 2As shown, in order to prevent the cement-based grouting material inside the temporary storage tube 2 from settling, a stirring shaft 23 can be set inside the temporary storage tube 2. A rotating wheel 24 is set at the upper end of the stirring shaft 23. The staff can rotate the rotating wheel 24 to drive the stirring shaft 23 to rotate, and the stirring blades are driven by the stirring shaft 23 to stir the cement-based grouting material to rotate.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
