Example

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A manual brake testing device for a truck comprises a chassis 1, wherein both left and right ends of the top of the chassis 1 are rotatably connected with fixed frames 2, the tops of the two groups of fixed frames 2 are provided with adjusting screws 3, the bottom ends of the front faces of the two groups of fixed frames 2 are rotatably connected with connecting arms 4, the inner sides of the two groups of fixed frames 2 are rotatably connected with fixed seats 5, the inner sides of the two groups of fixed seats 5 are fixedly connected with clamping plates 6, the brake bodies are clamped between the two groups of clamping plates 6, pressure sensors 7 are installed inside the two groups of fixed seats 5, the right end of the back side of the chassis 1 is fixedly connected with a support frame 8, the top of the support frame 8 is fixedly provided with a test motor 9, and the driving end of the test motor 9 is fixedly provided with a fixing member 10.

[0024] First, fixing holes 101 are opened at the four corners of the base frame 1, and the fixing frame 2 and the connecting arm 4 are rotatably connected to the base frame 1 through the connecting plate 102. The bottom of the base frame 1 is fixed through the fixing holes 101, and the fixing frame 2 and the connecting arm 4 are installed on the base frame 1 through the connecting plate 102.

[0025] Furthermore, the top ends of the two groups of fixed frames 2 are rotatably connected with a connecting block 201, the right end of the adjusting screw 3 is rotatably connected to the connecting block 201, the left end of the adjusting screw 3 is threadedly connected to the connecting block 201 through a connecting sleeve 202, the right end of the adjusting screw 3 is fixedly connected with an operating handle 203, and the left end of the adjusting screw 3 is fixedly connected to a limiting block 204. When the brake body is inspected, the adjusting screw 3 is rotated by the operating handle 203, and the two groups of fixed frames 2 are first opened under the connection of the connecting sleeve 202, so that the brake body can be conveniently placed between the two groups of fixed frames 2. After the brake body is placed, the adjusting screw 3 is rotated by the operating handle 203 to gather the two groups of fixed frames 2, so that the brake body is clamped and fixed by the clamping plate 6, thereby saving the time for disassembling and assembling the brake body and greatly improving the efficiency of inspection.

[0026] Then, the ends of the two groups of connecting arms 4 that are close to each other are rotatably connected by the rotating shaft 401, and the ends of the two groups of connecting arms 4 that are far away from each other are threadedly connected with the first fixing stud 402, and the bottom ends of the two groups of fixing frames 2 and the outsides of the first fixing stud 402 are fixedly connected with fixing blocks 403. Before the fixation inspection of the brake body, the first fixing stud 402 is unscrewed to release the fixation between the connecting arm 4 and the fixing frame 2, so as to facilitate the opening of the fixing frame 2 into the brake body. After the brake body is clamped and fixed, the first fixing stud 402 is screwed on to fix the two groups of fixing frames 2 using the two groups of connecting arms 4.

[0027] Furthermore, the clamping plate 6 is a hard rubber plate, and the upper and lower ends of the clamping plate 6 are fixedly connected to the fixing seat 5 by mounting bolts 601. A through groove 602 adapted for use with the pressure sensor 7 is provided on the inner side of the clamping plate 6. The clamping plate 6 made of hard rubber plate can ensure the fixing effect of the brake body while avoiding pinching the outer side of the brake body. The clamping plate 6 is fixed by mounting bolts 601 for easy disassembly and replacement. The pressure sensor 7 is located in the inner side of the through groove 602. When the brake body is tested, the pressure sensor 7 contacts the outer side of the brake body. The brake body is opened to make it against the pressure sensor 7, and the braking force is detected by observing whether the reading of the pressure sensor 7 is normal.

[0028] Secondly, the fixing part 10 includes a connecting box 1001 fixedly connected to the output shaft of the test motor 9, the left end of the connecting box 1001 is rotatably connected to the fixing box 1002, and the right side of the fixing box 1002 is fixedly connected by a second fixing stud 1003. When the brake body is tested, the brake shaft is placed into the inner side of the connecting box 1001 while being clamped and fixed, and then the fixing box 1002 is covered and fixed by the second fixing stud 1003. When the brake body is tested, the brake shaft is driven to rotate by the test motor 9, thereby controlling the outer side of the brake body to open, and it presses against the pressure sensor 7 to detect the braking force.

[0029] Finally, the inner sides of the connecting box 1001 and the fixing box 1002 are fixedly connected with a fixing sleeve 1004, which is a hard rubber sleeve. The fixing sleeve 1004 made of the hard rubber sleeve can fix the brake shaft of the brake body while avoiding damage to the outer side of the brake shaft.

[0030] In this embodiment, the implementation scenario is specifically as follows: when the brake body is tested, the bottom of the base frame 1 is fixed through the fixing hole 101, the first fixing stud 402 is screwed out to release the fixation between the connecting arm 4 and the fixing frame 2, the adjusting screw 3 is rotated by the operating handle 203, and the two sets of fixing frames 2 are first opened under the connection of the connecting sleeve 202, so that the brake body can be placed between the two sets of fixing frames 2. After the brake body is placed, the adjusting screw 3 is rotated by the operating handle 203 to gather the two sets of fixing frames 2, so that the brake body is clamped and fixed by the clamping plate 6. After the brake body is clamped and fixed, the first fixing stud 402 is screwed on to use Two groups of connecting arms 4 are fixed between two groups of fixed frames 2. While clamping and fixing them, their brake shafts are placed inside the connecting box 1001, and then the fixed box 1002 is covered and fixed by the second fixing stud 1003. When the brake body is tested, the brake shaft is driven to rotate by the test motor 9, thereby controlling the outer side of the brake body to open, which is against the pressure sensor 7. By observing whether the reading of the pressure sensor 7 is normal, the braking force is tested. The whole operation process is simple and convenient. Compared with the existing detection method of the truck brake, the utility model can improve the detection efficiency of the truck brake through design.
