Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, and more specifically, to a tunnel top water spraying device for tunnel construction. Background Technology

[0002] Tunnels are structures built underground, underwater, or in mountains to lay railways or construct highways for motor vehicles. The construction process of road tunnels mainly involves tunnel planning, surveying, design, breakthrough control surveying, and construction. During tunnel construction, water spraying devices are used to moisten the cement on the tunnel walls to prevent rapid drying and cracking. Water spraying devices can also be used to regulate the temperature and humidity inside the tunnel and to extinguish any open flames.

[0003] A search revealed a Chinese patent application with patent number 202021723353.1, which discloses a tunnel top water sprinkler device for tunnel construction, belonging to the field of tunnel construction technology. The device includes a base plate, the upper surface of which is fixedly connected to the bottom end of a column. A water supply pipe is provided on the inner wall of the column, and the top end of the water supply pipe is movably connected to the bottom end of a sleeve. A bearing is fixedly connected to the outer surface of the sleeve, and the bearing is connected to a rotating wheel via a transmission belt. A wheel disc is provided on the upper surface of the rotating wheel.

[0004] The above-mentioned patent has the following shortcomings: 1. When spraying the tunnel top through the nozzle, the nozzle is not easy to move, resulting in a relatively limited spraying area, which makes it difficult to improve the comprehensiveness of the spraying of the tunnel top and thus affects the efficiency of the work; 2. During the spraying of the tunnel top, excessive water flow is often generated, which is not easy to effectively collect the excess water, which not only wastes water resources, but also hinders the management of the site environment and the sustainable use of resources.

[0005] Therefore, there is an urgent need for a tunnel top water spraying device for tunnel construction to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the current problems of limited spraying area and inefficiency when spraying the tunnel roof with nozzles, which is caused by the limited movement of the nozzles and thus hinders the comprehensive coverage of the tunnel roof. Furthermore, excessive water flow is often generated during tunnel roof spraying, making it difficult to effectively collect the excess water, resulting in water waste and hindering on-site environmental management and sustainable resource utilization.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A tunnel roof water spraying device for tunnel construction, to improve the above-mentioned problems.

[0009] The application is as follows:

[0010] A tunnel top watering device for tunnel construction includes a vehicle body and a sliding frame fixedly connected to the top wall of the vehicle body. An adjustable frame is slidably connected to the inner wall of the sliding frame, and a spray ring is rotatably connected to the top wall of the adjustable frame. Two sets of spray rings are symmetrically arranged about the central axis of the adjustable frame. A first gear is fixedly connected to the side wall of the spray ring. A swing assembly for driving the spray ring to reciprocate is slidably connected to the top wall of the adjustable frame. A water-saving component is connected to the top wall of the adjustable frame, and evenly distributed wheel hubs are rotatably connected to the bottom wall of the vehicle body.

[0011] As a preferred technical solution of this application, the swing assembly includes a reciprocating frame slidably connected to the top wall of the height adjustment frame. The reciprocating frame is symmetrically arranged in two sets about the central axis of the height adjustment frame. The side wall of the reciprocating frame is provided with a first tooth groove. The reciprocating frame is connected to a first gear through the first tooth groove. The end of the reciprocating frame away from the first tooth groove is also provided with a second tooth groove.

[0012] As a preferred technical solution of this application, a support plate is fixedly connected to the top wall of the height adjustment frame, a drive motor is fixedly connected to the top wall of the support plate, a crank plate is rotatably connected to the bottom wall of the support plate, the output end of the drive motor is fixedly connected to the crank plate, a slip ring is fixedly connected to the top wall of one set of the reciprocating frame, the output end of the crank plate is also slidably connected to the slip ring, a second gear is rotatably connected to the top wall of the height adjustment frame, and the reciprocating frame is meshed with the second gear through a second tooth groove.

[0013] As a preferred technical solution of this application, the water-saving component includes an inclined plate fixedly connected to the top wall of the height adjustment frame. Two sets of inclined plates are symmetrically arranged about the central axis of the height adjustment frame. A filter groove is opened on the inner wall of the inclined plate. A water collection tank is fixedly connected to the bottom wall of the height adjustment frame. The inclined plate is connected to the water collection tank through the filter groove. A hose is fixedly connected to the side wall of the water collection tank. The end of the hose away from the water collection tank is also connected to a spray ring. A water pump is fixedly connected to the outer wall of the hose. The water collection tank, hose and spray ring are connected.

[0014] As a preferred technical solution of this application, a cylinder is fixedly connected to the top wall of the vehicle body, and the output end of the cylinder is fixedly connected to the height adjustment frame.

[0015] In the scheme of this application:

[0016] 1. When moving via the reciprocating frame, the first gear is deflected by the action of the first tooth groove, which in turn drives the spraying ring to swing back and forth, increasing the spraying range and improving work efficiency. This solves the problem in the prior art that when spraying the tunnel top through the nozzle, the spraying area is limited due to the inconvenience of the nozzle's movement, which makes it difficult to improve the comprehensiveness of the spraying of the tunnel top and thus affects the work efficiency.

[0017] 2. By tilting the plate, the dripping water can be concentrated in the middle, and the filtered water can be discharged into the collection tank through the filter tank, which can improve the utilization rate of water resources. This solves the problem that in the existing technology, excessive water flow is often generated during the spraying of the tunnel top, which is not easy to effectively collect excess water. This not only wastes water resources, but also hinders the management of the site environment and the sustainable use of resources. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] like Figures 1-3 As shown, this embodiment proposes a tunnel top watering device for tunnel construction, including a vehicle body 100 and a sliding frame 101 fixedly connected to the top wall of the vehicle body 100. An adjustable frame 102 is slidably connected to the inner wall of the sliding frame 101, and a spraying ring 103 is rotatably connected to the top wall of the adjustable frame 102. Two sets of spraying rings 103 are symmetrically arranged about the central axis of the adjustable frame 102. A first gear 104 is fixedly connected to the side wall of the spraying ring 103. A swinging component for driving the spraying ring 103 to reciprocate is slidably connected to the top wall of the adjustable frame 102. A water-saving component is connected to the top wall of the adjustable frame 102. Evenly distributed wheel hubs 105 are rotatably connected to the bottom wall of the vehicle body 100. The spraying ring 103 can reciprocate, thereby increasing the spraying range of the tunnel top.

[0027] like Figures 1-5 As shown, in a preferred embodiment, based on the above method, the swing assembly further includes a reciprocating frame 110 slidably connected to the top wall of the height adjustment frame 102. The reciprocating frame 110 has two sets symmetrically arranged about the central axis of the height adjustment frame 102. The side wall of the reciprocating frame 110 is provided with a first tooth groove 111. The reciprocating frame 110 is meshed with the first gear 104 through the first tooth groove 111. The end of the reciprocating frame 110 away from the first tooth groove 111 is also provided with a second tooth groove 112. The first gear 104 can be driven to rotate through the first tooth groove 111, thereby improving the linkage.

[0028] like Figures 1-6 As shown, in a preferred embodiment, based on the above method, a support plate 113 is fixedly connected to the top wall of the height adjustment frame 102, a drive motor 114 is fixedly connected to the top wall of the support plate 113, a crank plate 115 is rotatably connected to the bottom wall of the support plate 113, and the output end of the drive motor 114 is fixedly connected to the crank plate 115. A slip ring 116 is fixedly connected to the top wall of one set of reciprocating frames 110, and the output end of the crank plate 115 is also slidably connected to the slip ring 116. A second gear 117 is rotatably connected to the top wall of the height adjustment frame 102, and the reciprocating frame 110 is meshed with the second gear 117 through the second tooth groove 112. By sliding the crank plate 115 in the slip ring 116, the reciprocating frames 110 on both sides can be driven to reciprocate on the top of the height adjustment frame 102 simultaneously through the slip ring 116, which is more practical.

[0029] like Figures 1-6As shown, in a preferred embodiment, based on the above method, the water-saving component further includes an inclined plate 120 fixedly connected to the top wall of the height adjustment frame 102. Two sets of inclined plates 120 are symmetrically arranged about the central axis of the height adjustment frame 102. A filter groove 121 is opened on the inner wall of the inclined plate 120. A water collection tank 122 is fixedly connected to the bottom wall of the height adjustment frame 102. The inclined plate 120 is connected to the water collection tank 122 through the filter groove 121. A hose 123 is fixedly connected to the side wall of the water collection tank 122. The end of the hose 123 away from the water collection tank 122 is also connected to the spray ring 103. A water pump 124 is fixedly connected to the outer wall of the hose 123. The water collection tank 122, the hose 123 and the spray ring 103 are connected. Under the action of the inclined plate 120, excess water can be collected, thereby improving the utilization rate of water resources.

[0030] like Figures 1-2 As shown, in a preferred embodiment, based on the above method, a cylinder 130 is fixedly connected to the top wall of the vehicle body 100, and the output end of the cylinder 130 is fixedly connected to the height adjustment frame 102. The cylinder 130 is convenient to adapt to tunnels of different heights and is more convenient to use.

[0031] Specifically, when using this tunnel top water spraying equipment for tunnel construction: First, the vehicle body 100 is pushed to the required position by the action of the wheel hub 105. Then, the cylinder 130 is started to drive the height adjustment frame 102 to slide out from the sliding frame 101, adjusting the two sets of spray rings 103 to a position suitable for the tunnel top. By starting the water pumps 124 on both sides, water from the water collection tank 122 is transported to the spray rings 103 through the hoses 123, and sprayed out through the spray rings 103, thereby achieving spraying of the tunnel top. At the same time, the drive motor 114 is started to drive the crank plate 115 to slide within the slip ring 116, thereby driving the slip ring 116 to reciprocate. One set of reciprocating frames 110 was moved, and the second gear 117 was driven to rotate by the second tooth groove 112. The second gear 117 synchronously drove the other reciprocating frame 110 to move. When the reciprocating frame 110 moved, the first gear 104 was driven to deflect by the first tooth groove 111. When the first gear 104 deflected, the spraying ring 103 was reciprocated, thereby increasing the spraying range on the top of the tunnel and improving work efficiency. The water sprayed on the top of the tunnel dripped onto the inclined plate 120 and then entered the water collection tank 122 under the action of the filter tank 121, thereby improving the utilization rate of water resources and making it more practical.
