Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a three-dimensional spraying and dust reduction device for building demolition construction. Background Technique

[0002] When demolishing a building, a large amount of dust will inevitably be generated. Therefore, it is necessary to carry out dust reduction treatment on the demolished building. Usually, the building is dust-reduced by spraying. When the dust reduction area is large, it is necessary to drag the spray pipe device to the dust reduction area, or carry the water supply system and the spray structure to the designated spray area respectively;

[0003] For example, Chinese Patent No. CN107413144A discloses a three-dimensional spraying and dust reduction system for building demolition construction, including a spray structure, a vertical support structure, a horizontal support structure, a connection structure, a water supply system, a movable foundation and a support. Among them, the vertical support structure includes several vertical rods, and the several vertical rods are connected and fixed by connecting pieces and bolt a. The lower end of the vertical support structure is installed in the column foot through bolt b. The column foot is inserted into the slot of the movable foundation and fixed by a positioning screw. The horizontal support structure is composed of several horizontal support rods. One end of the horizontal support structure is connected to the vertical support structure through a connection structure and a support member. The support member is fixed to the lower end of the horizontal support structure and the vertical support structure by screws;

[0004] In the prior art, although the spray structure can spray the building demolition construction from multiple angles, it is necessary to move the water supply system and the spray structure separately, which is not convenient for handling. At the same time, during the handling process, it is easy to cause pulling on the connection between the water supply system and the spray structure, shortening the service life of the system.

Detailed Embodiment

[0026] In order to enable those skilled in the art to better understand this utility model, the technical solutions of this utility model will be further described below with reference to the drawings and embodiments.

[0027] As Figures 1-4As shown in the figure, a three-dimensional spraying and dust suppression device for building demolition construction includes an installation platform 1 and a motor 101. An electric push rod 11 arranged vertically is installed on one side of the installation platform 1, and a telescopic rod assembly 12 parallel to the electric push rod 11 is installed on the other side of the installation platform 1. A lead screw 13 is assembled and connected to the upper sides of the telescopic rod assembly 12 and the electric push rod 11. The output shaft of the motor 101 is in transmission connection with the lead screw 13. A limiting plate 14 is arranged below the lead screw 13. A translation member 15 is threadedly connected to the lead screw 13. The translation member 15 is slidably connected to the limiting plate 14. A spray head swing assembly 16 is arranged on the upper side of the translation member 15. The spray head swing assembly 16 is assembled and connected to a spray head 17. The spray head 17 is connected to a water supply system 2.

[0028] Adopting the technical solution of this embodiment, the installation platform 1 installs the dust suppression device. The electric push rod 11 can extend up and down. The telescopic rod assembly 12 plays an auxiliary supporting role for the lead screw 13. The telescopic rod assembly 12 can be adjusted according to the height of the electric push rod 11 and can be fixed when adjusted to the same position as the electric push rod 11. The motor 101 drives the lead screw 13 to rotate. When the lead screw 13 rotates, the translation member 15 moves. Since the limiting plate 14 restricts the sliding of the translation member 15, the translation member 15 cannot rotate. By controlling the rotation of the lead screw 13, the movement of the translation member 15 is controlled. The translation member 15 drives the spray head swing assembly 16 to move, and the spray head 17 suppresses the dust generated during building demolition construction. The water supply system 2 supplies water to the spray head 17.

[0029] Refer to Figure 1 : The water supply system 2 includes a hose 201, a water tank 202 and a water pump. One end of the hose 201 is communicated with the spray head 17 and the other end is communicated with the water pump. The water pump is located in the water tank 202, and the water tank 202 is located in the middle of the upper side of the installation platform 1.

[0030] In this embodiment, the water tank 202 supplies water to the hose 201, the water pump transports the water in the water tank 202 into the hose 201, and the water in the hose 201 is transferred to the spray head 17.

[0031] Refer to Figure 1 : Universal wheels 3 are provided at the four corners of the lower side of the installation platform 1.

[0032] In this embodiment, the universal wheels 3 facilitate the labor-saving movement of the spraying and dust suppression device. At the same time, the universal wheels 3 are equipped with brakes, and the spraying and dust suppression device can be stationary when working.

[0033] Refer to Figure 1 : A handle 18 is fixedly connected to one side of the installation platform 1.

[0034] In this embodiment, the handle 18 is convenient for dragging the spraying and dust suppression device.

[0035] Refer to Figures 1-2:The nozzle swing assembly 16 includes a square frame 161, a swing pipe 162, a hinge 163 and two positioning seats 164. The square frame 161 is fixedly connected to the upper side of the translation member 15. The swing pipe 162 is rotatably connected to the middle of the square frame 161 through the hinge 163. The opening of the swing pipe 162 is in the same direction as the opening of the square frame 161. The two positioning seats 164 are symmetrically arranged on the lower side of the swing pipe 162. When the swing pipe 162 is tilted, the positioning seat 164 contacts the square frame 161. One of the positioning seats 164 has magnetism, and the positioning seat 164 with magnetism is connected to a control assembly 165.

[0036] In this embodiment, the translation member 15 drives the square frame 161 to move. A spray head 17 is placed in the swing pipe 162. When the bottom surface of the positioning seat 164 contacts the square frame 161, the swing pipe 162 is placed obliquely. The control assembly 165 adsorbs and controls the bottom of the positioning seat 164, thereby controlling the movement of the swing pipe 162.

[0037] Refer to Figure 1 :The control assembly 165 includes a micro motor 1651 and an iron sheet 1652. The micro motor 1651 is assembled and connected to the translation member 15. The output shaft of the micro motor 1651 is drivingly connected to the iron sheet 1652. When the iron sheet 1652 rotates, it is located below the positioning seat 164.

[0038] In this embodiment, the micro motor 1651 controls the rotation of the iron sheet 1652. When the iron sheet 1652 rotates to below the positioning seat 164, the positioning seat 164 adsorbs the iron sheet 1652, and the positioning seat 164 contacts the iron sheet 1652. When the iron sheet 1652 rotates to another direction, the positioning seat 164 disengages from the iron sheet. The swing pipe 162 swings in the other direction under the action of gravity, thereby driving the spray head 17 to swing. Thus, when the iron sheet 1652 rotates, the swing pipe 162 swings reciprocally.

[0039] Refer to Figure 3 :The telescopic rod assembly 12 includes an outer rod 121 and an inner rod 122. The inner rod 122 is located inside the outer rod 121 and is slidably connected to the outer rod 121. The upper end of the outer rod 121 is provided with a thread. The inner rod 122 is slidably connected to a tapered threaded sleeve 123 with an opening. The tapered threaded sleeve 123 is threadedly connected to an outer threaded sleeve 124, and the outer threaded sleeve 124 matches the thread at the upper end of the outer rod 121.

[0040] In this embodiment, the inner rod 122 slides within the outer rod 121. When the inner rod 122 is slid upward to the desired height, the external thread sleeve 124 is rotated downward and helically connected to the thread of the outer rod 121. Since the tapered thread sleeve 123 is provided with an opening, when the external thread sleeve 124 is rotated downward, the opening of the tapered thread sleeve 123 tightens, and the frictional force between the tapered thread sleeve 123 and the inner rod 122 increases, fixing the relative positions of the inner rod 122 and the outer rod 121 by the external thread sleeve 124.

[0041] Refer to Figure 3 : A number of ribs 1241 are annularly arrayed on the outer surface of the external thread sleeve 124.

[0042] In this embodiment, the ribs 1241 are used to facilitate the rotation of the external thread sleeve 124.

[0043] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in this field. Moreover, the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0044] The above embodiments only exemplarily illustrate the principle and its effects of the present utility model, rather than being used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
