DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Figure 1-Figure 3As shown, a front-cage jack pressure detection device with a protective structure includes a base plate 100, a fixing mechanism 200, a detection mechanism 300 and a protective mechanism 400.

[0022] The fixing mechanism 200 is installed on the top surface of the bottom plate 100, and the fixing mechanism 200 is used to clamp and fix the jack 500. The detection mechanism 300 is installed on the top surface of the bottom plate 100, and the detection mechanism 300 is used to detect the jack 500. The detection mechanism 300 includes a steel wire rope 305, and the steel wire rope 305 is used to connect with the jack 500; the protection mechanism 400 is installed on the top surface of the bottom plate 100, and the protection mechanism 400 is used to prevent the steel wire rope 305 from being separated from the jack 500 and swinging to injure people.

[0023] The jack 500 mentioned in this article is a front cassette jack 500 .

[0024] Specifically, the jack 500 to be tested is first placed on the base plate 100, the jack 500 is clamped and fixed by the fixing mechanism 200, and then the steel wire rope 305 is fixed by the jack 500, and then the steel wire rope 305 is pulled by the jack 500 to move, and then the pressure test is performed.

[0025] During detection, when the taut steel wire rope 305 suddenly breaks, the protection mechanism 400 can prevent the steel wire rope 305 from swinging and injuring people.

[0026] like Figure 3 and Figure 4 As shown, the detection mechanism 300 further includes a fixed plate 301 , a movable plate 302 , a plurality of first springs 303 , a pressing plate 304 and a pressure detector 306 .

[0027] The fixed plate 301 is fixedly connected to the top surface of the bottom plate 100; the movable plate 302 is slidably connected to the bottom plate 100, and circular grooves are provided on the movable plate 302 and the fixed plate 301; the two ends of the first spring 303 are fixedly connected to the fixed plate 301 and the movable plate 302 respectively; the extrusion plate 304 is located on the side of the movable plate 302 away from the fixed plate 301, and the extrusion plate 304 is fixedly connected to one end of the steel wire 305, and the steel wire 305 runs through the fixed plate 301 and the movable plate 302; in order to improve the stability of the extrusion plate 304, a support plate (not shown) is provided on the side of the movable plate 302 close to the extrusion plate 304, and the support plate is used to support the extrusion plate 304, and when the steel wire 305 is in a non-tight state, the extrusion plate 304 can still be placed vertically and contact the surface of the movable plate 214. The pressure detector 306 is installed on the movable plate 302, and the pressure detector 306 contacts the extrusion plate 304, and the pressure detector 306 can be a pressure sensor.

[0028] Specifically, when the jack 500 pulls the wire rope 305 to move, it will drive the extrusion plate 304 to move, and then the extrusion plate 304 pushes the movable plate 302 to move in the direction close to the fixed plate 301. When the extrusion plate 304 pushes the movable plate 302 to move, the pressure detector 306 will detect the pressure caused by the extrusion plate 304 on the movable plate 302. When the pressure reaches the preset value, the jack 500 is controlled to maintain this state for a period of time. After a period of time, if the pressure detected by the pressure detector 306 still exceeds or is equal to the preset value, it means that the test result of the jack 500 is qualified. On the contrary, if the pressure detected by the pressure detector 306 is less than the preset value, it means that the test result of the jack 500 is unqualified.

[0029] like Figure 4 As shown, the front card jack pressure detection device with a protective structure also includes two first slots 101 and two first slide grooves 102. The two first slots 101 are both opened on the top surface of the bottom plate 100; the two first slide grooves 102 are both opened on the top surface of the bottom plate 100. Two sliders 307 are installed on the bottom surface of the moving plate 302, and the two sliders 307 are slidably connected with the two first slide grooves 102 respectively.

[0030] like Figure 3 , Figure 5 and Figure 6 As shown, the fixing mechanism 200 includes a bracket 201, a clamping plate 202, a limiting plate 203 and an adjusting assembly 210. The bracket 201 is mounted on the top surface of the base plate 100, and the bracket 201 is used to support the jack 500; the clamping plate 202 is mounted on the top surface of the bracket 201; the limiting plate 203 is used to cooperate with the clamping plate 202 to clamp and fix the jack 500, and the limiting plate 203 is slidably connected to the top surface of the base plate 100; the adjusting assembly 210 is used to adjust the distance between the limiting plate 203 and the clamping plate 202.

[0031] Specifically, the jack 500 to be tested is placed on the bracket 201, the head of the jack 500 is placed in the clamping plate 202, and the position of the limit plate 203 is adjusted by the adjustment component 210, so that the limit plate 203 contacts the tail of the jack 500, and the clamping plate 202 and the limit plate 203 cooperate to clamp and fix the jack 500, so as to avoid the accuracy of the test result being affected by the displacement of the jack 500 during the test.

[0032] like Figure 6 As shown, the adjustment assembly 210 includes two fixed tooth plates 211 , two second slide slots 212 , two mounting frames 213 , two movable plates 214 , two movable tooth plates 215 and a connecting plate 216 .

[0033] The two fixed tooth plates 211 are both installed on the side of the bracket 201 away from the detection mechanism 300, and the two fixed tooth plates 211 are both penetrated through the through slots provided on the limit plate 203. The two second slide slots 212 are respectively provided on the two fixed tooth plates 211; the two mounting frames 213 are respectively slidably connected with the two second slide slots 212, and the two mounting frames 213 are both connected with the limit plate 203; the two movable plates 214 respectively penetrate the two mounting frames 213 and are slidably connected with the mounting frames 213; the two movable tooth plates 215 are respectively installed on the bottom surfaces of the two movable plates 214, and the movable tooth plates 215 are engaged and connected with the fixed tooth plates 211; the connecting plate 216 is fixedly connected with the top surfaces of the two movable plates 214.

[0034] Specifically, when the position of the limit plate 203 needs to be adjusted, the connecting plate 216 is pulled upward to drive the two movable plates 214 to move upward, thereby driving the two movable tooth plates 215 to move upward, thereby separating the movable tooth plates 215 from the fixed tooth plates 211, so that the mounting frame 213 can move along the second slide groove 212, and the limit plate 203 can move along the two fixed tooth plates 211. When the position adjustment of the limit plate 203 is completed, by loosening the connecting plate 216, the two movable tooth plates 215 will move downward under the influence of gravity, thereby engaging the movable and fixed tooth plates 211, so that the two mounting frames 213 cannot slide; thereby, the fixing mechanism 200 can adapt to jacks 500 of different sizes.

[0035] like Figure 7-Figure 10 As shown, the protection mechanism 400 includes two vertical rods 401, a connecting rod 402, two nuts 403 and four sets of protection components 410. The two vertical rods 401 are respectively plugged into the two first slots 101, one of the vertical rods 401 is provided with a first card slot 4011, and the other vertical rod 401 is provided with a first card block 4012; the connecting rod 402 passes through the two vertical rods 401; the two nuts 403 are respectively fixedly connected to the two ends of the connecting rod 402; and the four sets of protection components 410.

[0036] Specifically, four groups of protection components 410 and two vertical rods 401 form a "door" shaped structure. During detection, when the taut wire rope 305 suddenly breaks, when the wire rope 305 swings, the wire rope 305 will swing onto the "door" shaped structure. The "door" shaped structure can reduce the impact force of the wire rope 305 being swung, and can also reduce the length of the wire rope 305 being swung outward, thereby preventing the wire rope 305 from swinging and injuring people.

[0037] like Fig.10As shown, the protection assembly 410 includes a transverse plate 411, a second clamping block 412, a second clamping slot 413, a plurality of dampers 414, a protection plate 415, and a plurality of second springs 416. The second clamping block 412 is mounted on the side of the transverse plate 411, and the second clamping block 412 is plugged and matched with the first clamping slot 4011; the second clamping slot 413 is provided on the side of the transverse plate 411, and the second clamping slot 413 is plugged and matched with the second clamping block 412 and the first clamping block 4012; the plurality of dampers 414 are all mounted on the bottom surface of the transverse plate 411; the protection plate 415 is arranged in an "L" shape, and the protection plate 415 is fixedly connected to the lower ends of the plurality of dampers 414; the two ends of the second spring 416 are fixedly connected to the transverse plate 411 and the protection plate 415, respectively.

[0038] Specifically, by providing a second card block 412 and a second card slot 413 on the horizontal plate 411, the four horizontal plates 411 can be plugged into each other, and the horizontal plates 411 can also be plugged into the vertical rods 401, so that the four horizontal plates 411 and the two vertical rods 401 form a "door" shaped structure.

[0039] By providing the damper 414 and the second spring 416 , when the steel wire rope 305 swings upward and hits the protective plate 415 , the second spring 416 will be deformed, thereby reducing the impact force of the steel wire rope 305 on the protective plate 415 , thereby protecting the protective plate 415 .

[0040] Working principle: During specific use, the jack 500 to be tested is placed on the bracket 201, the head of the jack 500 is placed in the clamping plate 202, and then the connecting plate 216 is pulled upward to drive the two movable plates 214 to move upward, thereby driving the two movable tooth plates 215 to move upward, thereby separating the movable tooth plates 215 from the fixed tooth plates 211, so that the mounting frame 213 can move along the second slide groove 212, and the limit plate 203 can move along the two fixed tooth plates 211, so that the limit plate 203 contacts the tail of the jack 500, and the clamping plate 202 and the limit plate 203 cooperate to clamp and fix the jack 500, so as to avoid the accuracy of the test result being affected by the displacement of the jack 500 during the test.

[0041] When the position adjustment of the limiting plate 203 is completed, by loosening the connecting plate 216, the two movable tooth plates 215 will move downward under the influence of gravity, thereby engaging the movable and fixed tooth plates 211, so that the two mounting frames 213 cannot slide.

[0042] Then insert one end of the wire rope 305 into the jack 500, fix the wire rope 305 by the jack 500, and then pull the wire rope 305 by the jack 500 to move, which will drive the extrusion plate 304 to move, and then the extrusion plate 304 pushes the movable plate 302 to move in the direction close to the fixed plate 301. When the extrusion plate 304 pushes the movable plate 302 to move, the pressure detector 306 detects the pressure caused by the extrusion plate 304 on the movable plate 302. When the pressure reaches the preset value, the jack 500 is controlled to maintain this state for a period of time. After a period of time, if the pressure detected by the pressure detector 306 still exceeds or is equal to the preset value, it means that the test result of the jack 500 is qualified. On the contrary, if the pressure detected by the pressure detector 306 is less than the preset value, it means that the test result of the jack 500 is unqualified.

[0043] Among them, by setting up the protection mechanism 400, during the detection, when the taut wire rope 305 suddenly breaks, when the wire rope 305 swings, the wire rope 305 will swing onto the protection mechanism 400. The protection mechanism 400 can reduce the impact force of the wire rope 305 being thrown, and can also reduce the length of the wire rope 305 being thrown outward, thereby avoiding the wire rope 305 from swinging and injuring people.

[0044] Example 2: Figure 2 , Fig.11 and Fig.12 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: The protection assembly 410 further includes a roller 417 and a limiting groove 418. The roller 417 is mounted on the bottom surface of the protection plate 415; and the limiting groove 418 is provided on the top surface of the horizontal plate 411.

[0045] The front card jack pressure detection device with a protective structure also includes four support blocks 103 and two second slots 104. The four support blocks 103 are all installed on the bottom surface of the bottom plate 100, and the support blocks 103 are plugged into the limit grooves 418; the two second slots 104 are both opened on the top surface of the bottom plate 100, and the second slots 104 are plugged into the vertical rod 401.

[0046] Working principle: When the device needs to be moved, the nut 403 is rotated so that the nut 403 no longer abuts against the vertical rod 401 , so that there is a gap between the two vertical rods 401 and the four protective components 410 .

[0047] Then, the four protection components 410 are sequentially moved away from the fixing plate 301 to separate the four protection components 410 from each other.

[0048] Then, place a horizontal plate 411 in a protective component 410 under the base plate 100, so that the support block 103 on the base plate 100 is plugged into the limiting groove 418 on the horizontal plate 411, and repeat the above operation to plug the limiting grooves 418 on the remaining three horizontal plates 411 into another three support blocks 103, so that the base plate 100 is not in contact with the ground and the four moving wheels are in contact with the ground.

[0049] Then, the two vertical rods 401 are removed from the two slots, and then the two vertical rods 401 are flipped so that the connecting rod 402 is at the top, and then the two vertical rods 401 are plugged into the two second slots 104 so that the two vertical rods 401 and the connecting rod 402 act as temporary pushers, thereby facilitating the movement of the bottom plate 100.

[0050] When the vehicle encounters a bumpy road, the plurality of dampers 414 and the plurality of second springs 416 cooperate to provide buffering for the bottom plate 100 , thereby protecting the bottom plate 100 and the components located on the top surface of the bottom plate 100 .

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
