[0026] Example 1

[0027] like Figure 1-Figure 3 As shown, the utility model provides a military vehicle shock absorber detection tool, including a base 1 and a rotating bracket 2, one end of the base 1 is fixedly provided with a hydraulic push rod 3, the other end of the base 1 is fixedly provided with a limit device 4, and a clamping space for clamping the shock absorber is formed between the hydraulic push rod 3 and the limit device 4; the rotating bracket 2 is rotatably connected to the base 1, and a hydraulic cylinder 5 is fixedly provided on the rotating bracket 2, and the hydraulic cylinder 5 is connected to the hydraulic push rod 3 through a hydraulic pipeline 6; a distance measuring device 7 is provided on the base 1.

[0028] Specifically, the hydraulic push rod 3 and the hydraulic oil cylinder 5 are the contents of the prior art, and their structures are not described in detail. Figure 1The hydraulic cylinder 5 exemplarily shown in the figure selects a double-acting hydraulic cylinder, which is connected to the hydraulic jack 3 through two hydraulic pipelines 6. The extension and retraction of the hydraulic jack 3 are driven by hydraulic pressure. A manual reversing valve is arranged on the hydraulic cylinder 5 to change the flow direction of the hydraulic oil. A lever socket (sleeve structure) is arranged on the hydraulic cylinder 5. During work, a crowbar is used to be inserted into the socket to press and perform hydraulic action.

[0029] In this embodiment, when not in use, the rotating bracket 2 is rotated to be closed with the base 1, so that the volume of the entire device is very small, which is convenient for carrying and transporting.

[0030] When in use, the rotating bracket 2 is rotated to open at a right angle or a wide angle with the base 1, and then the shock absorber is placed between the hydraulic push rod 3 and the limit device 4. The crowbar is inserted into the lever socket of the hydraulic cylinder 5 and pressed to extend the hydraulic push rod 3 to gradually clamp and compress the shock absorber. The extension distance of the hydraulic push rod 3 is read according to the measurement value of the distance measuring device 7 to determine the damage of the shock absorber.

[0031] The degree of damage to the shock absorber can be judged by comparing the impact value / impact resistance during the compression stroke with the standard value (for example, the standard impact value of the HOWO ZZ2197 cab shock absorber is 13200Pa), and by comparing the recovery value / recovery resistance during the recovery stroke with the standard value (for example, the standard recovery resistance of HOWO ZZ2197 is 1000N). The impact value and the recovery value can be obtained by directly reading the values ​​on the distance measuring device 7, and the impact resistance and the recovery resistance can be obtained by multiplying the reading on the distance measuring device 7 by the pressure represented by the unit hydraulic stroke.

[0032] Example 2

[0033] A running wheel 8 is provided at the bottom of one end of the base 1 .

[0034] Specifically, when in use, the base 1 forms a trolley structure through the running wheels 8, and the other end of the base 1 can be lifted to place the device on the ground and move forward through the running wheels 8. Carrying and transporting are more convenient.

[0035] Example 3

[0036] A vertical support 9 is provided on the end of the base 1 away from the walking wheel 8. The end of the rotating support 2 is rotatably connected to the vertical support 9. The hydraulic cylinder 5 is arranged on the end of the rotating support 2 away from the vertical support 9. The fixed end of the hydraulic jack 3 is detachably connected to the vertical support 9.

[0037] Specifically, the vertical bracket 9 is a short bracket, which is vertically welded to the end of the base 1 to form an L-shaped structure with the base 1. A hole is provided in the middle of the vertical bracket 9, so that the tail fixed end of the hydraulic jack 3 is bolted to the vertical bracket 9 through the hole. An annular clamping ring is provided on the base 1, and the body of the hydraulic jack 3 is inserted into the clamping ring, so that the hydraulic jack 3 is detachably fixed as a whole.

[0038] There are also multiple holes on the upper part of the vertical bracket 9. One of the holes is selected to be bolted to the bottom end of the rotating bracket 2 (a bare bolt with threads at both ends and a bare rod in the middle, which does not affect the rotation of the rotating bracket 2). Then the rotating bracket 2 can be rotated to open or close. The hydraulic cylinder 5 is fixedly installed on the top of the rotating bracket 2 by bolts. The bottom of the hydraulic cylinder 5 is connected to the hydraulic push rod 3 through two hydraulic pipelines 6 to control the telescopic action.

[0039] Example 4

[0040] The telescopic end of the hydraulic push rod 3 is connected to a clamp head 301, and the end surface of the clamp head 301 is provided with a V-shaped structure clamping groove. The limit device 4 includes a clamp seat 401, and the clamp seat 401 is provided with a clamping groove for embedding the fixed end of the shock absorber. The groove walls on both sides of the clamping groove are provided with locking holes 402, and rods are inserted through the locking holes 402 and the fixed end of the shock absorber.

[0041] Specifically, the clamp head 301 is made of steel and has good hardness. The V-shaped structure slot can clamp the ball connection end (not shown) of the shock absorber, thereby preventing the shock absorber from falling out when pressurized. The clamp seat 401 is a U-shaped structure with a slot in the middle. The ball connection end of the shock absorber is also clamped into the slot of the clamp seat 401, and a pin rod (not shown) is inserted into the bolt connection hole on the shock absorber and the through lock hole 402 on the slot, so that the end of the shock absorber is fixed by the pin rod and the shock absorber is prevented from falling out.

[0042] Example 5

[0043] The distance measuring device 7 comprises a scale.

[0044] Specifically, the distance measuring device 7, such as a steel ruler, is fixed to the surface of the base 1 by rivets or the like and is located on one side of the hydraulic jack 3, so as to facilitate observation of the moving distance of the hydraulic jack 3 when the hydraulic jack 3 is extended or retracted.

[0045] The use of this device:

[0046] When not in use, the rotating bracket 2 is rotated to close with the base 1, so that the volume of the entire device is very small. The device can be lifted at one end and the walking wheel 8 at the other end is grounded, which can be easily moved and semicircular, and is easy to carry and transport.

[0047] When in use, the rotating bracket 2 is rotated to open at a right angle or a wide angle with the base 1, and then the shock absorber is placed between the hydraulic push rod 3 and the limit device 4. The crowbar is inserted into the lever socket of the hydraulic cylinder 5 and pressed to extend the hydraulic push rod 3 to gradually clamp and compress the shock absorber. The extension change stroke of the hydraulic push rod 3 is read according to the measurement value of the distance measuring device 7 to determine the damage of the shock absorber.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
