Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting water guns, and in particular to a testing device for rotating parts of fire-fighting water guns. Background Art

[0002] A fire hose is a water-shooting tool used for firefighting. After being connected to a water hose, it can spray dense and substantial water flows. According to the different jet forms and characteristics, it can be divided into direct current water guns, spray water guns and multi-purpose water guns. Water guns are usually composed of an interface, a gun body, a switch and a nozzle. For water guns with rotating parts such as switch switching, direct current spray switching, flow gear switching, dual flow channel switching, and flushing function switching, the rotating parts should be subjected to 300 reciprocating operation tests, and no jamming or damage should occur.

[0003] At present, the testing of the rotating parts of fire hoses is all done manually. Due to the high labor intensity and the frequent occurrence of insufficient rotation angles and times, the test quality and efficiency are low, resulting in inaccurate test results. Therefore, in order to reduce the workload of the staff, the fire hose is clamped and fixed to make the fire hose rotate automatically, which can reduce manual operation and human interference factors, thereby improving the test quality and efficiency.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0021] like Figure 1 - Figure 7 As shown, a test device for a rotating part of a fire hose gun comprises a mounting shell 1, two first clamping assemblies 5 and two second clamping assemblies 6, a receiving plate 2 is provided at the left rear end of the mounting shell 1, a rotating device 3 is provided at the upper front end of the receiving plate 2, the rotating device 3 penetrates the mounting shell 1, the rotating device 3 is fixedly connected to the first clamping assembly 5 at the rear, the mounting shell 1 is fixedly connected to the first clamping assembly 5 at the front, the two second clamping assemblies 6 are fixedly connected to the first clamping assembly 5 at the rear, and a feeding device 4 is provided at the bottom of the mounting shell 1; The feeding device 4 can be used to feed a large number of fire-fighting water guns without manual feeding, thereby reducing the labor burden of the staff and increasing the working efficiency of the device. After the feeding is completed, the two first clamping components 5 are used to fix the fire-fighting water gun. Since the device detects the rotating parts of the water gun, the front first clamping component 5 can fix the rear of the water gun. At the same time, the front first clamping component 5 is fixed to the mounting shell 1, so the front first clamping component 5 is fixed, and the rear first clamping component 5 is fixed to the fire-fighting water gun. The front part of the water gun is fixed, and the two second clamping assemblies 6 can clamp the middle part of the fire water gun, so that the fire water gun is more stable during rotation. Since the rotating device 3 is fixedly connected to the first clamping assembly 5 at the rear, the rotating device 3 will drive the first clamping assembly 5 at the rear to rotate, so that the front part of the fire water gun is rotated, so as to test the fire water gun. The rotating device 3 can not only rotate the front part of the fire water gun clockwise, but also rotate the fire water gun counterclockwise, so as to test the rotating parts more fully.

[0022] like Figure 2 As shown, the feeding device 4 includes a feeding shell 40 and a lifting assembly 43. The feeding shell 40 is fixedly connected to the mounting shell 1. A material storage cavity 44 is provided in the middle of the feeding shell 40. A material storage plate 41 is provided on the upper part of the material storage cavity 44. A feeding assembly 42 is provided on the left end of the material storage plate 41. The upper part of the lifting assembly 43 is slidably connected to the feeding shell 40. A plurality of fire hoses can be placed on the upper part of the material storage plate 41 so that a large number of fire hoses can be tested, thereby making the device more applicable. Since the upper surface of the material storage plate 41 is an inclined surface, the fire hose can be moved to the left more easily. The fire hose can be loaded using the loading assembly 42 without manual loading. When the fire hose moves to the upper end of the lifting assembly 43, the lifting assembly 43 can be used to move the fire hose upwards to between the two first clamping assemblies 5. Then, the two first clamping assemblies 5 can be used to fix the fire hose without manual loading, thereby reducing the labor burden of the staff.

[0023] like Figure 3 As shown, the feeding assembly 42 includes a reciprocating assembly 420 and a slide 423, the reciprocating assembly 420 is slidably connected to the slide 423, an ejection device 421 is provided at the upper end of the slide 423, and a fixing plate 422 is provided at the front and rear ends of the ejection device 421, and the two fixing plates 422 are fixedly connected to the feeding shell 40; The reciprocating assembly 420 can be used to make the ejection device 421 reciprocate up and down. During the reciprocating motion, the ejection device 421 will also work, so that the fire hose cannon moves to the upper end of the lifting assembly 43, so as to load the materials.

[0024] like Figure 4 As shown, the reciprocating assembly 420 includes a first motor 4200, a reciprocating shaft 4201 is provided at the output end of the first motor 4200, a reciprocating plate 4202 is provided at the left end of the reciprocating shaft 4201, a sliding column 4203 is provided on the left end of the reciprocating plate 4202 away from the reciprocating shaft 4201, and the sliding column 4203 is slidably connected to the slideway 423; When the first motor 4200 is started, the reciprocating shaft 4201 will rotate, thereby causing the reciprocating plate 4202 to rotate. Since the reciprocating shaft 4201 is fixed to the edge of the reciprocating plate 4202, when the reciprocating plate 4202 rotates, the sliding column 4203 will slide on the inner surface of the slide 423, so that the slide 423 reciprocates up and down, thereby driving the ejection device 421 to work.

[0025] For details, please refer to Figure 5The ejection device 421 includes a connecting rod 4211 and a support plate 4212, both of which are fixedly connected to the slideway 423. A reciprocating housing 4210 is provided at the upper end of the connecting rod 4211, a load-bearing block 4213 is provided at the upper end of the support plate 4212, and ejection assemblies 4215 are provided at the front and rear sides of the load-bearing block 4213. The two ejection assemblies 4215 are used in conjunction with the fixed plate 422 on the same side, and two buffer springs 4214 are provided at the middle of the upper end of the load-bearing block 4213. A driven assembly 4216 is provided at the upper ends of the two buffer springs 4214, and the driven assembly 4216 is slidably connected to the reciprocating housing 4210; Since many fire hoses are stored on the upper part of the storage plate 41, when the slide 423 moves to the lowest point, the fire hose on the leftmost side of the storage plate 41 will move to the upper part of the reciprocating shell 4210. When the slide 423 moves upward, the support plate 4212 and the connecting rod 4211 will move upward. The upward movement of the connecting rod 4211 will cause the reciprocating shell 4210 to move upward, thereby causing the fire hose on the upper part of the reciprocating shell 4210 to move upward. When the support plate 4212 gradually moves upward, the two ejection components 4215 will touch the fixed plates 422 on both sides, thereby causing the driven component 4216 to be ejected upward, thereby causing the fire hose on the upper end of the reciprocating shell 4210 to move to the upper end of the lifting component 43.

[0026] like Figure 6 As shown, the ejection assembly 4215 includes an ejection block 1500, which is movably connected to the load-bearing block 4213, and pulleys 1501 are provided on both the front and rear sides of the ejection block 1500; The driven assembly 4216 includes a driven plate 1600, a driven column 1601 is provided at the middle of the upper end of the driven plate 1600, an ejection plate 1602 is provided at the upper end of the driven column 1601, and the lower end of the driven plate 1600 is fixedly connected to two buffer springs 4214; When the support plate 4212 drives the load-bearing block 4213 to move upward, the two ejection components 4215 and the driven component 4216 will also move upward. Since the ejection block 1500 is movably connected with the load-bearing block 4213, and the shape of the ejection block 1500 is similar to the shape of a check mark, when the two pulleys 1501 touch the fixed plates 422 on both sides, the ejection block 1500 will rotate, thereby causing the driven plate 1600 to be ejected upward, thereby causing the driven column 1601 and the ejection plate 1602 to be ejected upward, thereby causing the fire hose on the upper surface of the reciprocating shell 4210 to be ejected upward, thereby causing the fire hose to move to the upper end of the lifting component 43 and then be clamped.

[0027] like Figure 7As shown, the lifting assembly 43 includes a fixed block 430, which is fixedly connected to the feeding shell 40, driving the upper end of the fixed block 430 to be provided with a first telescopic rod 431, and the upper end of the first telescopic rod 431 is provided with a lifting plate 432, and the shape of the lifting plate 432 is arc-shaped; When the fire hose moves to the upper end of the lifting plate 432, the lifting plate 432 is arc-shaped, which can better accommodate the fire hose, so that the fire hose is more secure during the upward movement. The first telescopic rod 431 can be used to drive the lifting plate 432 to move up and down, and finally the fire hose is moved between the two first clamping assemblies 5.

[0028] The specific implementation method is as follows: a large number of fire-fighting water guns are placed on the upper part of the storage plate 41. After the first motor 4200 is started, the reciprocating shaft 4201 will rotate, thereby rotating the reciprocating plate 4202, and sliding the sliding column 4203 on the inner surface of the slide 423, so that the slide 423 reciprocates up and down. Many fire-fighting water guns are stored on the upper part of the storage plate 41. Therefore, when the slide 423 moves to the lowest point, the fire-fighting water gun on the leftmost side of the storage plate 41 will move to the upper part of the reciprocating shell 4210. When the slide 423 moves upward, the support plate 4212 and the connecting rod 4211 will move upward. The upward movement of the connecting rod 4211 will cause the reciprocating shell 4210 to move upward, thereby The fire hose on the upper part of the reciprocating shell 4210 moves upward, and when the support plate 4212 gradually moves upward, the load-bearing block 4213 moves upward, and when the two pulleys 1501 touch the fixed plates 422 on both sides, the ejection block 1500 rotates, thereby causing the driven plate 1600 to be ejected upward, thereby causing the driven column 1601 and the ejection plate 1602 to be ejected upward, thereby causing the fire hose on the upper surface of the reciprocating shell 4210 to be ejected upward, thereby causing the fire hose to move to the upper end of the lifting plate 432, and starting the first telescopic rod 431 will cause the lifting plate 432 to move upward, thereby causing the fire hose to move to the position between the two first clamping assemblies 5, thereby clamping and fixing the fire hose. Embodiment 2

[0029] This embodiment further improves the first clamping assembly 5 and the rotating device 3 on the basis of the first embodiment. Figure 8 - Fig.11 As shown, after the fire hose is loaded, the two first clamping assemblies 5 can be used to clamp and fix the fire hose, and then the rotating device 3 can be used to rotate the front of the fire hose clockwise and counterclockwise, so as to fully detect the fire hose, thereby making the detection effect of the device more accurate.

[0030] like Figure 8As shown, the first clamping assembly 5 includes a limit plate 50 and a second rack 57. A second telescopic rod 51 is provided at the left end of the limit plate 50. A first rack 52 is provided at the output end of the second telescopic rod 51. A first gear 54 is provided on the lower surface of the first rack 52. The first gear 54 is meshed with the second rack 57. A synchronization rod 55 is provided at one end of the first rack 52 and the second rack 57 away from the mounting housing 1. A clamping block 56 is provided at one end of the two synchronization rods 55 close to each other. A sliding block 53 is provided on the outer surface of the second telescopic rod 51 and the second rack 57. Starting the second telescopic rod 51 will move the first rack 52, which will cause the first gear 54 to rotate, thereby driving the second rack 57 to move, so that the first rack 52 and the second rack 57 move in opposite directions, thereby clamping the fire hose. The front first clamping assembly 5 can clamp and fix the rear of the fire hose, and the position of the rear is fixed. Since the rear first clamping assembly 5 is fixedly connected to the rotating device 3, the rotating device 3 will drive the front of the fire hose to rotate, thereby fully testing the fire hose.

[0031] like Fig. 9 As shown, the second clamping assembly 6 includes an L-shaped rod 60, the L-shaped rod 60 is fixedly connected to the clamping block 56, and a protective plate 61 is provided at the front end of the L-shaped rod 60; The rear clamping block 56 is fixedly connected to the second clamping assembly 6, so the L-shaped rod 60 and the protective plate 61 will move with the movement of the clamping block 56, thereby clamping the middle part of the fire hose, making the fire hose more stable during the rotation process, thereby making the detection result more accurate.

[0032] like Fig.10 As shown, the rotating device 3 includes a second motor 30, a second test assembly 33 and a repetitive assembly 32. The output end of the second motor 30 is provided with a first test assembly 31. The first test assembly 31 is wound and connected with the second test assembly 33. The first test assembly 31 and the second test assembly 33 are used in conjunction with the repetitive assembly 32. The structure of the first test assembly 31 is the same as that of the second test assembly 33. A connecting plate 34 is provided at the front end of the repetitive assembly 32. The second motor 30 will cause the first test component 31 to rotate. Since the first test component 31 is entangled and connected with the second test component 33, when the first test component 31 is working, it will drive the second test component 33 to work as well, and will also cause the repetitive component 32 to work, so that the connecting plate 34 will rotate clockwise and counterclockwise, so that the front part of the fire hose can be rotated, thereby fully testing the fire hose.

[0033] like Fig.11As shown, the first test assembly 31 includes a main shaft 310, a second gear 311 is disposed on the outer front of the main shaft 310, and a plurality of driving columns 312 are disposed on the front end of the second gear 311; The reciprocating assembly 32 includes a driving shaft 320, and a driving plate 321 is provided on the front of the outer surface of the driving shaft 320, and the driving plate 321 is slidably connected with a plurality of driving columns 312; Starting the second motor 30 will cause the main shaft 310 to rotate, thereby causing the second gear 311 to rotate. Since the outer surface of the driving plate 321 is provided with multiple grooves, when the second gear 311 rotates, the multiple driving columns 312 will also rotate. At the same time, when the driving columns 312 touch the grooves of the driving shaft 320, the driving plate 321 will be moved to rotate clockwise, thereby causing the fire hose to rotate clockwise. When the second gear 311 rotates, the second test assembly 33 will also work. When the second test assembly 33 rotates, the driving plate 321 will be moved counterclockwise, thereby causing the fire hose to rotate both clockwise and counterclockwise, thereby fully testing the fire hose. Since the test requires the front part of the fire hose to reciprocate 300 times, the number of rotations can be set by using the second motor 30.

[0034] The specific implementation method is as follows: when the fire hose moves to the position between the two first clamping assemblies 5, starting the second telescopic rod 51 will cause the first rack 52 to move, thereby causing the first gear 54 to rotate, thereby driving the second rack 57 to move, thereby causing the first rack 52 and the second rack 57 to move in opposite directions, thereby clamping the front and rear parts of the fire hose, and the rear clamping block 56 is fixedly connected to the second clamping assembly 6, so the L-shaped rod 60 and the protective plate 61 will move with the movement of the clamping block 56, thereby clamping the middle part of the fire hose, thereby making the fire hose more stable during the rotation process, and starting the second motor 30 will cause the main shaft 310 to rotate, thereby causing the second gear 311 to rotate, and when the set driving column 312 touches the groove of the driving shaft 320, it will move the driving plate. 321 rotates clockwise, so that the fire hose rotates clockwise, and when the second gear 311 rotates, the second test assembly 33 also works, and the second test assembly 33 rotates to move the driving plate. 321 rotates counterclockwise, so that the fire hose rotates both clockwise and counterclockwise, so as to fully test the fire hose.
