Description

Technical Field

[0001] The present application relates to the technical field of subway station construction, and in particular to a spray dust reduction device for subway station construction. Background Art

[0002] Subway stations are places for passengers to board, disembark, transfer and wait for trains. When subway stations are being constructed and excavated, a large amount of dust will be generated, which will pollute the surrounding air. A spray dust suppression device is needed to suppress the dust. However, ordinary spray dust suppression devices can only suppress dust in one direction or pitch angle when in use, which makes the dust suppression range of the spray dust suppression device small. Therefore, we proposed a spray dust suppression device for subway station construction. Utility Model Content

[0003] The present application provides a subway station construction spray dust reduction device to solve the above-mentioned problems.

[0004] This application provides a subway station construction spray dust suppression device, comprising:

[0005] A spray body, wherein the lower left end of the spray body is fixedly connected to a cylindrical rod and the outer end of the cylindrical rod is fixedly sleeved with a roller;

[0006] A circular arc plate, wherein the circular arc plate is provided with a wave-shaped through groove;

[0007] The roller is movably inserted into the through slot;

[0008] The outer side of the spray body is fixedly sleeved with a connecting ring, and the lower end of the connecting ring is connected to the rotating base through a rotating mechanism, and a connecting shaft is fixedly connected to the middle of the lower end of the rotating base. The outer side of the connecting shaft is sleeved with a gear for engaging a connecting rack, and the rack drives the gear to rotate.

[0009] Preferably, a connecting plate is fixedly connected to the lower end of the arc plate, and the connecting plate is fixedly connected to the side wall of the base.

[0010] Preferably, the rotating mechanism includes a connecting block and a connecting ear plate, the connecting block is rotatably connected to the middle part of the connecting ear plate through a rotating shaft, the upper end of the connecting block is fixedly connected to the lower end of the connecting ring, and the lower end of the connecting ear plate is fixedly connected to the upper end of the rotating base.

[0011] Preferably, the rotating base is rotatably inserted into the upper circular groove of the base.

[0012] Preferably, the lower portion of the connecting shaft is inserted into the interior of the base via a bearing.

[0013] Preferably, the rack is fixedly connected to the side wall of the transmission rod, and the transmission rod is movably inserted into the insertion groove opened on the outside of the base.

[0014] Preferably, the outer end of the transmission rod is fixedly connected with a transmission connecting plate, the transmission connecting plate is fixedly connected to the transmission rod of the electric telescopic rod, and the electric telescopic rod is fixedly inserted into the side wall of the base.

[0015] Preferably, the center of the arc plate coincides with the rotation center of the rotating base.

[0016] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0017] In the structure provided by the embodiment of the present application, the electric telescopic rod drives the transmission rod to move left and right, thereby causing the rack to move left and right, and then driving the gear to rotate, thereby driving the connecting shaft to rotate, and causing the rotating base to rotate, thereby causing the spray body to rotate. When the spray body rotates, since the end roller of the cylindrical rod is inserted into the through groove, the roller is forced to move along the through groove, thereby causing the spray body to move in pitch, thereby enabling the spray body to spray and reduce dust in multiple directions, and the power source for spraying and reducing dust in multiple directions only needs to be driven by an electric telescopic rod, which greatly saves power.

[0027] Figure 2 This is a top-sectional view of the base provided in an embodiment of the present application.

[0028] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a subway station construction spray dust suppression device, comprising:

[0029] A spray body 8, wherein a cylindrical rod 11 is fixedly connected to the lower left end of the spray body 8 and a roller 12 is fixedly sleeved on the outer end of the cylindrical rod 11;

[0030] A circular arc plate 9, wherein a wave-shaped through groove 10 is formed on the circular arc plate 9;

[0031] The roller 12 is movably inserted into the through slot 10;

[0032] The outer side of the spray body 8 is fixedly sleeved with a connecting ring 7, and the lower end of the connecting ring 7 is connected to the rotating base 2 through a rotating mechanism, and a connecting shaft 15 is fixedly connected to the middle of the lower end of the rotating base 2. The outer side of the connecting shaft 15 is sleeved with a gear 16 for engaging with a connecting rack 14, and the rack 14 drives the gear 16 to rotate.

[0033] Specifically: the spray body 8 adopts the existing cylindrical spray dust reduction device on the market;

[0034] The rack 14 drives the gear 16 to rotate within an angular range such that the roller 12 is at its farthest position at both ends of the through slot 10 .

[0035] like Figure 1 As shown: the lower end of the arc plate 9 is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the side wall of the base 1.

[0036] Specifically, the through slot 10 formed in the middle of the arc plate 9 serves as a displacement path for the roller 12 .

[0037] like Figure 1 As shown: the rotating mechanism includes a connecting block 6 and a connecting ear plate 5, the connecting block 6 is rotatably connected to the middle part of the connecting ear plate 5 through a rotating shaft, the upper end of the connecting block 6 is fixedly connected to the lower end of the connecting ring 7, and the lower end of the connecting ear plate 5 is fixedly connected to the upper end of the rotating base 2.

[0038] Specifically, the connection block 6 and the connection ear plate 5 are used in conjunction with each other to change the pitch angle of the spray body 8 .

[0039] like Figure 1 As shown: the rotating base 2 is rotatably inserted into the upper circular groove of the base 1.

[0040] Specifically, the rotating base 2 is inserted into the circular groove, which can make the rotation of the rotating base 2 more stable.

[0041] like Figure 2 As shown: the lower part of the connecting shaft 15 is inserted into the interior of the base 1 through a bearing.

[0042] Specifically, the connecting shaft 15 is rotatable.

[0043] like Figure 2 As shown, the rack 14 is fixedly connected to the side wall of the transmission rod 4, and the transmission rod 4 is movably inserted into the insertion groove 13 opened on the outside of the base 1.

[0044] Specifically, the displacement of the rack 14 can drive the gear 16 to rotate.

[0045] like Figure 1 As shown: the outer end of the transmission rod 4 is fixedly connected to a transmission connecting plate, the transmission connecting plate is fixedly connected to the transmission rod of the electric telescopic rod 3, and the electric telescopic rod 3 is fixedly inserted into the side wall of the base 1.

[0046] Specifically, the electric telescopic rod 3 adopts the existing telescopic rod on the market, and the electric telescopic rod 3 drives the transmission rod 4 to move left and right.

[0047] like Figure 1 As shown in FIG. 1 , the center of the arc plate 9 coincides with the center of rotation of the rotating base 2 .

[0048] Specifically, the coincidence of the centers of the circles enables the roller 12 to always move inside the through slot 10 , and to ensure that the roller 12 always moves inside the through slot 10 , the length of the roller 12 is greater than the thickness of the through slot 10 .

[0049] When the equipment is in use, when the spray body 8 is spraying and dust reduction, if dust reduction needs to be performed at multiple angles, the electric telescopic rod 3 is started. At this time, the electric telescopic rod 3 will drive the transmission rod 4 to move left and right, thereby causing the rack 14 to move left and right, and then drive the gear 16 to rotate, and drive the connecting shaft 15 to rotate, so that the rotating base 2 rotates, thereby causing the spray body 8 to rotate. When the spray body 8 rotates, since the end roller 12 of the cylindrical rod 11 is inserted into the through groove 10, the roller 12 will be forced to move along the through groove 10, thereby causing the spray body 8 to pitch and move, thereby enabling the spray body 8 to spray and reduce dust in multiple directions, and the power source for spraying and reducing dust in multiple directions only needs to be driven by one electric telescopic rod 3, which greatly saves power.

[0050] The foregoing is merely a list of specific embodiments of the present application, intended to enable those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but rather is intended to conform to the broadest scope consistent with the principles and novel features claimed herein.
