Detailed implementation manners

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: As Figures 1 - 3 shown, a front-caliper jack pressure detection device with a protection structure includes a bottom plate 100, a fixing mechanism 200, a detection mechanism 300, and a protection mechanism 400.

[0036] 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 flinging and hurting people after being separated from the jack 500.

[0037] The jack 500 mentioned in this article is a front-caliper jack 500.

[0038] Specifically, first place the jack 500 to be detected on the bottom plate 100, clamp and fix the jack 500 through the fixing mechanism 200, then fix the steel wire rope 305 through the jack 500, and then pull the steel wire rope 305 to move through the jack 500, so as to perform pressure detection.

[0039] During the detection, when the taut steel wire rope 305 suddenly breaks, the protection mechanism 400 can prevent the steel wire rope 305 from flinging and hurting people.

[0040] As Figure 3 and Figure 4 shown, the detection mechanism 300 further includes a fixing plate 301, a moving plate 302, a plurality of first springs 303, a pressing plate 304, and a pressure detector 306.

[0041] 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 both the movable plate 302 and the fixed plate 301; both ends of the first spring 303 are fixedly connected to the fixed plate 301 and the movable plate 302 respectively; the pressing plate 304 is located on the side of the movable plate 302 away from the fixed plate 301, the pressing plate 304 is fixedly connected to one end of the steel wire rope 305, and the steel wire rope 305 passes through the fixed plate 301 and the movable plate 302; in order to improve the stability of the pressing plate 304, a support plate (not shown) is provided on the side of the movable plate 302 close to the pressing plate 304, and the support plate is used to support the pressing plate 304. When the steel wire rope 305 is in a non-tight state, the pressing plate 304 can still be placed vertically and in surface contact with the movable plate 214. The pressure detector 306 is installed on the movable plate 302, the pressure detector 306 is in contact with the pressing plate 304, and the pressure detector 306 can be a pressure sensor.

[0042] Specifically, when the jack 500 pulls the steel wire rope 305 to move, it will drive the pressing plate 304 to move, and then make the pressing plate 304 push the movable plate 302 to move in the direction close to the fixed plate 301. When the pressing plate 304 pushes the movable plate 302 to move, the pressure detector 306 will detect the pressure exerted by the pressing 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 detection 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 detection result of the jack 500 is unqualified.

[0043] As Figure 4 shown, the front type jack pressure detection device with a protection structure further includes two first slots 101 and two first chutes 102. Both of the two first slots 101 are provided on the top surface of the bottom plate 100; both of the two first chutes 102 are provided on the top surface of the bottom plate 100. Two sliders 307 are installed on the bottom surface of the movable plate 302, and the two sliders 307 are respectively slidably connected to the two first chutes 102.

[0044] As Figure 3 、 Figure 5 and Figure 6 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 installed on the top surface of the bottom plate 100, and the bracket 201 is used to support the jack 500; the clamping plate 202 is installed 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 bottom plate 100; the adjusting assembly 210 is used to adjust the distance between the limiting plate 203 and the clamping plate 202.

[0045] Specifically, place the jack 500 to be detected on the bracket 201, place the head of the jack 500 in the clamping plate 202, and then adjust the position of the limiting plate 203 through the adjusting assembly 210 so that the limiting plate 203 contacts the tail of the jack 500, and the clamping plate 202 and the limiting plate 203 cooperate to clamp and fix the jack 500, avoiding affecting the accuracy of the detection result due to the displacement of the jack 500 during the detection.

[0046] As Figure 6 shown, the adjusting assembly 210 includes two fixed toothed plates 211, two second chutes 212, two mounting brackets 213, two movable plates 214, two movable toothed plates 215 and a connecting plate 216.

[0047] Both of the two fixed toothed plates 211 are installed on the side of the bracket 201 away from the detection mechanism 300, and both of the two fixed toothed plates 211 penetrate through the through slots opened on the limiting plate 203. The two second chutes 212 are respectively opened on the two fixed toothed plates 211; the two mounting brackets 213 are respectively slidably connected to the two second chutes 212, and both of the two mounting brackets 213 are connected to the limiting plate 203; the two movable plates 214 respectively penetrate through the two mounting brackets 213 and are slidably connected to the mounting brackets 213; the two movable toothed plates 215 are respectively installed on the bottom surfaces of the two movable plates 214, and the movable toothed plates 215 are engaged with the fixed toothed plates 211; the connecting plate 216 is fixedly connected to the top surfaces of the two movable plates 214.

[0048] Specifically, when the position of the limiting plate 203 needs to be adjusted, by pulling up the connecting plate 216, the two movable plates 214 are driven to move upward, and then the two movable toothed plates 215 are driven to move upward, so that the movable toothed plates 215 are separated from the fixed toothed plates 211, enabling the mounting brackets 213 to move along the second chutes 212 and enabling the limiting plate 203 to move along the two fixed toothed plates 211. When the position adjustment of the limiting plate 203 is completed, by releasing the connecting plate 216, affected by gravity, the two movable toothed plates 215 will move downward, and then the movable toothed plates will engage with the fixed toothed plates 211, making the two mounting brackets 213 unable to slide; thus enabling the fixing mechanism 200 to adapt to jacks 500 of different sizes.

[0049] As Figures 7 - 10 shown, the protection mechanism 400 includes two vertical rods 401, a connecting rod 402, two nuts 403 and four groups of protection components 410. The two vertical rods 401 are respectively inserted into the two first slots 101, a first clamping groove 4011 is opened on one of the vertical rods 401, and a first clamping block 4012 is installed on the other vertical rod 401; the connecting rod 402 penetrates through the two vertical rods 401; the two nuts 403 are respectively fixedly connected to the two ends of the connecting rod 402; four groups of protection components 410.

[0050] Specifically, four groups of protection components 410 and two vertical rods 401 form a "door" - shaped structure. During detection, when the tightly stretched steel wire rope 305 suddenly breaks and swings, the steel wire rope 305 will swing onto the "door" - shaped structure. The "door" - shaped structure can reduce the impact force when the steel wire rope 305 swings and also reduce the length of the outward swing of the steel wire rope 305, thus preventing the steel wire rope 305 from swinging and hurting people.

[0051] As Figure 10 shown, the protection component 410 includes a cross - plate 411, a second clamping block 412, a second clamping groove 413, a plurality of dampers 414, a protection plate 415, and a plurality of second springs 416. The second clamping block 412 is installed on the side of the cross - plate 411, and the second clamping block 412 is in plug - in fit with the first clamping groove 4011; the second clamping groove 413 is opened on the side of the cross - plate 411, and the second clamping groove 413 is in plug - in fit with the second clamping block 412 and the first clamping block 4012; a plurality of dampers 414 are all installed on the bottom surface of the cross - 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; both ends of the second spring 416 are fixedly connected to the cross - plate 411 and the protection plate 415 respectively.

[0052] Specifically, by arranging the second clamping block 412 and the second clamping groove 413 on the cross - plate 411, the four cross - plates 411 can be plugged into each other, and the cross - plate 411 can also be plugged into the vertical rod 401, so as to facilitate the four cross - plates 411 and the two vertical rods 401 to form a "door" - shaped structure.

[0053] By arranging the dampers 414 and the second springs 416, when the steel wire rope 305 swings upward and hits the protection plate 415, the second spring 416 will deform, thereby reducing the impact force of the steel wire rope 305 on the protection plate 415 and protecting the protection plate 415.

[0054] Working principle: During specific use, place the jack 500 to be detected on the bracket 201, place the head of the jack 500 in the clamping plate 202, then pull the connecting plate 216 upward to drive the two movable plates 214 to move upward, further drive the two movable tooth plates 215 to move upward, and then separate the movable tooth plate 215 from the fixed tooth plate 211, so that the mounting frame 213 can move along the second sliding groove 212, the limiting plate 203 can move along the two fixed tooth plates 211, make the limiting plate 203 contact with the tail of the jack 500, and make the clamping plate 202 and the limiting plate 203 cooperate to clamp and fix the jack 500, avoiding the displacement of the jack 500 during detection from affecting the accuracy of the detection result.

[0055] After the position of the limit plate 203 is adjusted, by loosening the connecting plate 216, under the influence of gravity, the two movable toothed plates 215 will move downward, and then the movable toothed plate will engage with the fixed toothed plate 211, making it impossible for the two mounting brackets 213 to slide.

[0056] Then, one end of the steel wire rope 305 is inserted into the jack 500. The steel wire rope 305 is fixed by the jack 500, and then the jack 500 is used to pull the steel wire rope 305 to move, which will drive the pressing plate 304 to move. Then, the pressing plate 304 will push the moving plate 302 to move in the direction close to the fixed plate 301. When the pressing plate 304 pushes the moving plate 302 to move, the pressure detector 306 will detect the pressure exerted by the pressing plate 304 on the moving 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 detection result of this 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 detection result of this jack 500 is unqualified.

[0057] Among them, by setting the protection mechanism 400, during the detection, when the tightly stretched steel wire rope 305 suddenly breaks and when the steel wire rope 305 swings, the steel wire rope 305 will swing onto the protection mechanism 400. The protection mechanism 400 can reduce the impact force of the steel wire rope 305 hitting and also reduce the length of the steel wire rope 305 swinging outwards, thus avoiding the steel wire rope 305 from hurting people when it swings.

[0058] Example 2: As Figure 2 、 Figure 11 and Figure 12 shown, in the case where other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0059] The protection component 410 further includes a roller 417 and a limiting groove 418. The roller 417 is installed on the bottom surface of the protection plate 415; the limiting groove 418 is opened on the top surface of the cross plate 411.

[0060] The front - clamping jack pressure detection device with a protection structure further 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 in plug - in fit with the limiting 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 in plug - in fit with the vertical rods 401.

[0061] Working principle: When the device needs to be moved, by rotating the nut 403, the nut 403 no longer abuts against the vertical rod 401, creating a gap between the two vertical rods 401 and the four protection components 410.

[0062] Then, by sequentially moving the four protective components 410 away from the fixed plate 301, the four protective components 410 are separated from each other.

[0063] Then, place the cross plate 411 in one of the protective components 410 under the bottom plate 100, so that the support block 103 on the bottom plate 100 is inserted into the limit slot 418 on the cross plate 411. Repeat the above operation to insert the limit slots 418 on the remaining three cross plates 411 into the other three support blocks 103, so that the bottom plate 100 is not in contact, and the four moving wheels are in contact with the ground.

[0064] Then, remove the two vertical rods 401 from the two slots, then flip the two vertical rods 401 so that the connecting rod 402 is on the top, and then insert the two vertical rods 401 into the two second slots 104, so that the two vertical rods 401 and the connecting rod 402 act as temporary push hands, thus facilitating the movement of the bottom plate 100.

[0065] When moving on a bumpy road section, the cooperation of the multiple dampers 414 and the multiple second springs 416 can 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.
