Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a dust suppression device for water-stabilized construction. Background Technology

[0002] Water-stabilized layer is short for cement-stabilized crushed stone layer. It is made by using cement-consolidated graded crushed stone, which is compacted and cured. Water-stabilized layer has high strength, rigidity and stability. For asphalt pavement, water-stabilized layer is the main load-bearing layer of the entire road structure. It is an important structure to ensure the stability of the entire road structure. It can effectively transfer the vertical load of the road to the subgrade. The mix proportion of water-stabilized layer should be tested in the laboratory in advance to determine the cement content and the ratio of coarse and fine aggregates, and at the same time determine the maximum dry density. For large quantities, water-stabilized layer can be mixed at a water-stabilized layer mixing plant. Dust suppression devices are required to suppress dust during the construction of water-stabilized layer.

[0003] After the existing water-stabilized layer is laid, it needs to be compacted by a road roller. Usually, workers follow behind the road roller and use water pipes to suppress the dust raised by the road roller. However, this dust suppression method makes the workers' labor intensity high and poses certain safety hazards during the work. Utility Model Content

[0006] A further improvement of this utility model is that the water spraying device includes: a first spray pipe disposed between a pair of support plates and connected to the water outlet pipe, wherein the first spray pipe is offset from the position of the road roller.

[0007] A further improvement of this utility model is that the first spray pipe is rotatably connected between a pair of support plates via a shaft, and one of the support plates is equipped with a drive mechanism for driving the shaft to rotate the first spray pipe, and the water outlet pipe is made of a flexible material.

[0008] A further improvement of this utility model is that the driving mechanism is a swing motor, the swing motor is fixed to the outside of one of the support plates, and the shaft includes a first shaft that movably passes through the corresponding support plate and is fixedly connected to the driving end of the swing motor and one end of the first spray pipe, and a second shaft that is fixedly connected to the other end of the first spray pipe and rotatably connected to the support plate on the other side.

[0009] A further improvement of this utility model is that the end of the second shaft is formed into a T-shaped end, and a T-shaped groove for embedding the T-shaped end is provided on the support plate on the other side.

[0010] A further improvement of this utility model is that the water spraying device includes a second spray pipe that is fixed along the width direction of the road roller body to the rear end of the road roller body and is connected to the water outlet pipe.

[0011] A further improvement of this utility model is that the top of the water tank is provided with a water inlet for replenishing water into the water tank.

[0018] like Figures 1-3As shown, this utility model discloses a dust suppression device for water-stabilized construction, comprising: a road roller body 1; a pair of support plates 101 symmetrically fixed on the left and right sides in front of the road roller body 1; a road roller 102 rotatably disposed between the pair of support plates 101; a water spraying device fixed between the pair of support plates 101 / on the road roller body 1 for dust suppression; a water tank 2 fixed on the road roller body 1; and a water pump 201, the pumping end of which is connected to the inside of the water tank 2, the outlet end of which is connected to an outlet pipe 202, and the other end of the outlet pipe 202 is connected to the water spraying device.

[0019] like Figure 1 , Figure 3 As shown, the water spraying device includes: a first spray pipe 205 disposed between a pair of support plates 101 and connected to a water outlet pipe 202, wherein the first spray pipe 205 is offset from the position of the road roller 102.

[0020] like Figures 2-4 As shown, the first spray pipe 205 is rotatably connected between a pair of support plates 101 via a shaft. One of the support plates 101 is equipped with a drive mechanism for driving the shaft to rotate the first spray pipe 205. The water outlet pipe 202 is made of a soft material.

[0021] like Figure 3 , Figure 4 As shown, the driving mechanism is a swing motor 3, which is fixed to the outside of one of the pair of support plates 101. The shaft includes a first shaft that moves through the corresponding support plate 101 and is fixedly connected to the driving end of the swing motor 3 and one end of the first spray pipe 205, and a second shaft 302 that is fixedly connected to the other end of the first spray pipe 205 and rotatably connected to the support plate 101 on the other side.

[0022] like Figure 4 As shown, the end of the second shaft 302 is formed into a T-shaped end, and a T-shaped groove 301 for the T-shaped end to be inserted is provided on the other side support plate 101. By setting the T-shaped end and the matching T-shaped groove 301, the first spray pipe 205 is prevented from falling out.

[0023] like Figure 2 , Figure 3 As shown, the water spraying device includes a second spray pipe 203 that is fixed along the width direction of the roller body 1 to the rear end of the roller body 1 and is connected to the water outlet pipe 202.

[0024] like Figures 1-3 As shown, the top of the water tank 2 is provided with a water inlet 206 for replenishing water into the water tank 2.

[0025] Better, such as Figures 1-3As shown, in this embodiment, a third spray pipe 204 connected to the water outlet pipe 202 is also included. The third spray pipe 204 is located between the support plates 101 and in front of the roller 102. The first spray pipe 205 is located behind the roller 102. By setting multiple spray pipes, the dust reduction effect is improved.

[0026] Better, such as Figure 2 , Figure 3 As shown in this embodiment, the outlet end of the water outlet pipe 202 is connected to a diversion pipe, which is divided into three branches, and the three branches are respectively connected to the second spray pipe 203, the third spray pipe 204, and the first spray pipe 205.

[0027] In this embodiment, as Figure 2 , Figure 3 As shown, the water outlet pipe 202 passes through the interior of the roller body 1 and extends to connect to the third spray pipe 205. The roller body 1 has a swing space so that when the third spray pipe 205 swings and drives the water outlet pipe 202 to swing, the water outlet pipe 202 can swing.

[0028] When using this invention, during the compaction of the water-stabilized layer, the worker can first turn on the water pump 201. After the water pump 201 is turned on, it can draw water from the water tank 2 and send it into the water outlet pipe 202. The water outlet pipe 202 will evenly send the water into the three spray pipes, so that the water can be sprayed out from the three spray pipes to suppress dust. At the same time, the swing motor 3 can also be turned on to drive the first spray pipe 205 to swing, so as to better suppress dust on the ground compacted by the roller 102. Compared with the existing water-stabilized layer construction dust suppression device, dust suppression can be carried out at the same time as compaction of the water-stabilized layer, without the need for workers to hold water pipes, which greatly reduces the labor intensity of workers and effectively protects the personal safety of workers.
