Description

Technical Field

[0001] This utility model relates to the field of spray device technology, and more specifically, to a water-saving spray device for a body-in-white dismantling site. Background Technology

[0002] Body-in-white refers to the welded but unpainted and uninstalled body structure, mainly consisting of the body frame and body panels. Disassembling the body-in-white is primarily for the recycling of end-of-life vehicles. Disassembly allows for the classification and recycling of components made of different materials (such as steel and aluminum alloys), improving material reuse rates. It is also used in automotive repair; when a part of the body is damaged, the relevant parts are disassembled for replacement or repair. Furthermore, during the automotive research and development phase, body-in-white disassembly is performed to study body structure and component performance. Disassembly of the body-in-white generates dust, requiring dust suppression through a spray system while preventing overheating.

[0003] Currently, the water-saving spraying devices at existing body-in-white dismantling sites generally have fixed nozzles. In workstations where a lot of dust is generated during body-in-white dismantling, the only way to improve the spraying effect is to add more nozzles, which consumes a lot of water and is difficult to meet the current concept of water conservation. Therefore, we propose a water-saving spraying device for body-in-white dismantling sites. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a water-saving spraying device for the dismantling site of a white body, so as to solve the technical problem that the existing water-saving spraying devices at the white body dismantling site rely on adding nozzles to improve the spraying effect and consume a large amount of water.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water-saving spraying device for a body-in-white dismantling site, comprising a plurality of water-gathering pipes arranged at equal intervals, a water inlet hose on one side of the plurality of water-gathering pipes, a plurality of water mist nozzles arranged at equal intervals at the bottom of the water pipes, and a pitch-changing mechanism on the top of the plurality of water-gathering pipes.

[0006] The output end of the water inlet hose is fixedly connected to one end of each of the several water collection pipes;

[0007] The variable pitch mechanism includes a top frame. Mounting plates are provided at the bottom of the top frame relative to the water collection pipe. The mounting plates are movably connected to the water collection pipe. Short rods are rotatably connected to the top of the mounting plates on both sides, and long rods are rotatably connected to the top of the remaining mounting plates. One end of each of the two short rods is rotatably connected to one end of the adjacent long rod. The ends of several long rods are sequentially rotatably connected. A motor A is fixedly mounted on the inner wall of one end of the top frame. A lead screw is fixedly connected to the output end of motor A. One end of the lead screw is rotatably connected to the top frame via a mounting bearing. A C-shaped support frame is fixedly mounted on the top of the mounting plate away from motor A. A threaded sleeve is provided on the top of the C-shaped support frame, and the threaded sleeve is fitted onto the surface of the lead screw. The two ends of the top of the mounting plate closest to motor A are fixedly connected to the inner wall of the top of the top frame via connecting plates.

[0008] Preferably, one end of the mounting plate is rotatably connected to one end of the water collection pipe via a mounting ring, and the other end of the mounting plate is provided with a reciprocating component.

[0009] Preferably, the reciprocating assembly includes a C-shaped mounting frame, one outer wall of which is fixedly connected to the other end of the mounting plate. A rotating shaft is rotatably connected inside the C-shaped mounting frame. One end of the rotating shaft passes through one side of the C-shaped mounting frame and is fixedly connected to the other end of the water collection pipe. Two bevel gears are symmetrically sleeved on the surface of the rotating shaft. A motor B is fixedly mounted on the top of the C-shaped mounting frame. The output end of the motor B passes through the top of the C-shaped mounting frame and is fixedly connected to a half-tooth bevel gear. The half-tooth bevel gear meshes with the two bevel gears in sequence.

[0010] Preferably, both ends of the mounting plate have through holes penetrating the plate body.

[0011] Preferably, two sliding rods are fixedly installed at both ends of the bottom of the top frame relative to the through holes, and the two sliding rods are respectively inserted through the through holes at both ends of the mounting plates.

[0012] Preferably, the top frame has several mounting holes on both sides of its top.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The variable pitch mechanism designed in this utility model involves motor A driving a lead screw to rotate. The lead screw, through a threaded sleeve and a C-shaped support frame, drives a through hole on a mounting plate away from motor A to slide along a sliding rod. The mounting plate away from motor A pulls an adjacent long rod via a short rod, and the long rod pulls another adjacent long rod, thereby changing the inclination angle of the short and long rods, and thus changing the distance between two adjacent mounting plates, thereby changing the distance between the water collection pipes. Wide spraying or concentrated spraying can be selected according to the needs of the disassembly station. At the same time, stations that generate more dust can be set at the bottom of motor A in the variable pitch mechanism. When concentrated spraying is used, no additional nozzles are needed, thereby reducing water consumption.

[0015] 2. The reciprocating component designed in this utility model has a motor B that drives a half-tooth bevel gear to rotate. When the half-tooth bevel gear meshes with one of the bevel gears, it drives the rotating shaft to rotate clockwise. When the half-tooth bevel gear meshes with the other bevel gear, it drives the rotating shaft to rotate counterclockwise, which in turn drives the water collection pipe to reciprocate, thereby driving the water mist nozzle to reciprocate, thus improving the uniformity of spraying and further reducing water consumption.

[0022] like Figures 1 to 4As shown, this utility model relates to a water-saving spraying device for a body-in-white dismantling site, comprising several equally spaced water-collecting pipes 1, a water inlet hose 2 on one side of each water-collecting pipe 1, several water mist nozzles 3 evenly spaced at the bottom of each water pipe 1, and a pitch-changing mechanism 4 on the top of each water-collecting pipe 1; the output end of the water inlet hose 2 is fixedly connected to one end of each water-collecting pipe 1; in use, one end of the water inlet hose 2 is first connected to an external water control mechanism, and water is transported from the water inlet hose 2 to the water-collecting pipe 1 and sprayed out as water mist through the water mist nozzles 3.

[0023] Specifically, such as Figures 1 to 3 As shown, the variable pitch mechanism 4 includes a top frame 401. Mounting plates 402 are provided at the bottom of the top frame 401 relative to the water collection pipe 1. The mounting plates 402 are movably connected to the water collection pipe 1. Short rods 403 are rotatably connected to the top of the mounting plates 402 on both sides. Long rods 404 are rotatably connected to the top of the remaining mounting plates 402. One end of each of the two short rods 403 is rotatably connected to one end of the adjacent long rod 404. Several long rods 404 are rotatably connected at both ends in sequence. A motor A405 is fixedly installed on the inner wall of one end of the top frame 401. A lead screw 406 is fixedly connected to the output end of motor A405. One end of the lead screw 406 is rotatably connected to the top frame 401 via a mounting bearing. A C-shaped support frame 407 is fixedly installed on the top of the mounting plate 402 away from motor A405. The top of the C-shaped support frame 407 is provided with a threaded sleeve 408, which is fitted onto the surface of the lead screw 406. The two ends of the top of the mounting plate 402 near motor A405 are fixedly connected to the inner wall of the top of the top frame 401 via connecting plates. Both ends of the mounting plate 402 have through-hole openings. The through hole 4021 is fixedly installed at both ends of the bottom of the top frame 401 relative to the position of the through hole 4021. The two slide rods 410 are respectively inserted through the through holes 4021 at both ends of several mounting plates 402. The external control mechanism drives the motor A405 to drive the lead screw 406 to rotate. The lead screw 406 drives the through hole 4021 on the mounting plate 402 away from the motor A405 to slide along the slide rod 410 through the threaded sleeve 408 and the C-shaped support frame 407. The mounting plate 402 away from the motor A405... 2. The short rod 403 pulls the adjacent long rod 404, and the long rod 404 pulls the adjacent long rod 404, thereby changing the tilt angle of the short rod 403 and the long rod 404, thus changing the distance between the two adjacent mounting plates 402, thereby changing the distance between the water collection pipes 1. Wide spraying or concentrated spraying can be selected according to the needs of the disassembly station. At the same time, the station that generates more dust can be set at the bottom of the motor A405 in the pitch mechanism 4. When concentrated spraying, no additional nozzles are needed, thereby reducing water consumption.

[0024] Furthermore, such as Figures 1 to 4As shown, one end of the mounting plate 402 is rotatably connected to one end of the water collection pipe 1 via a mounting ring. The other end of the mounting plate 402 is provided with a reciprocating assembly 409, which includes a C-shaped mounting frame 4091. One outer wall of the C-shaped mounting frame 4091 is fixedly connected to the other end of the mounting plate 402. A rotating shaft 4092 is rotatably connected inside the C-shaped mounting frame 4091. One end of the rotating shaft 4092 passes through one side of the C-shaped mounting frame 4091 and is fixedly connected to the other end of the water collection pipe 1. Two bevel gears 4093 are symmetrically sleeved on the surface of the rotating shaft 4092. A motor B4094 is fixedly mounted on the top of the C-shaped mounting frame 4091. The output end of 094 is inserted through the top of the C-shaped mounting frame 4091 and fixedly connected to a half-tooth bevel gear 4095. The half-tooth bevel gear 4095 meshes with two bevel gears 4093 in sequence. The motor B4094 driven by the external control mechanism drives the half-tooth bevel gear 4095 to rotate. When the half-tooth bevel gear 4095 meshes with one of the bevel gears 4093, it drives the rotating shaft 4092 to rotate clockwise. When the half-tooth bevel gear 4095 meshes with the other bevel gear 4093, it drives the rotating shaft 4092 to rotate counterclockwise, which drives the water collection pipe 1 to swing back and forth, and then drives the water mist nozzle 3 to swing back and forth, thereby improving the uniformity of spraying.

[0025] Furthermore, such as Figure 1 , Figure 2 As shown, several mounting holes 4011 are provided on both sides of the top of the top frame 401 to facilitate the installation of the top frame 401 with the top of the workshop.

[0026] Working Principle: This embodiment provides a water-saving spraying device for a body-in-white dismantling site. During use, the work area generating more dust is positioned at the bottom of motor A405 in the pitch-changing mechanism 4. One end of the water inlet hose 2 is connected to an external water control mechanism. Water is transported from the water inlet hose 2 to the water collection pipe 1 and sprayed out as a water mist through the water mist nozzles 3. When the spraying area needs to be increased, the external control mechanism drives motor A405 to rotate the lead screw 406. The lead screw 406, through the threaded sleeve 408 and the C-shaped support frame 407, drives the through hole 4021 on the mounting plate 402 away from motor A405 to slide forward along the slide rod 410. The mounting plate 402 away from motor A402 pulls the adjacent long rod 404 via the short rod 403, and the long rod 404 pulls the adjacent long rod 404, thereby causing the short rod 403 and the long rod 404 to tilt. The reduced angle of inclination increases the distance between two adjacent mounting plates 402, thereby changing the distance between the water collection pipes 1 and increasing the spray area. The external control mechanism drives the motor B4094 to rotate the semi-bevel gear 4095. When the semi-bevel gear 4095 meshes with one of the bevel gears 4093, it drives the rotating shaft 4092 to rotate clockwise. When the semi-bevel gear 4095 meshes with the other bevel gear 4093, it drives the rotating shaft 4092 to rotate counterclockwise, causing the water collection pipe 1 to oscillate back and forth, which in turn drives the water mist nozzle 3 to oscillate back and forth, thereby improving the uniformity of spraying. When concentrated spraying is required, the external control mechanism drives the motor A405 to reverse the screw 406, increasing the inclination angle of the short rod 403 and the long rod 404, thereby reducing the distance between two adjacent mounting plates 402 and achieving concentrated spraying.
