[0027] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes the single hydraulic prop pressure test equipment of an embodiment of the present application with reference to the accompanying drawings.

[0029] like Figures 1-8 As shown, the single hydraulic support pressure test equipment of the embodiment of the present application may include: a base 1, a lower support assembly 2, a drive assembly 3 and an upper support assembly 4.

[0030] The lower support assembly 2 includes a base 21, two limiting rods 22, a support block 23 and a pressure sensor 24, wherein:

[0031] The base 21 is set on the base 1, and a groove body 211 is opened on the base 21. The inner bottom wall of the groove body 211 is opened with a first groove 212. Two limiting rods 22 are symmetrically arranged on the side walls of the groove body 211. The shape of the support block 23 is adapted to the shape of the first groove 212.

[0032] A second groove 231 is provided on the support block 23, and a plurality of rubber rings 233 are provided on the inner wall of the second groove 231. Guide grooves 232 are respectively provided on both sides of the support block 23. One end of the two limit rods 22 is respectively slidably provided inside the guide grooves 232, and the pressure sensor 24 is installed at the bottom of the first groove 212.

[0033] One end of the driving assembly 3 is arranged inside the base 1 , and the other end of the driving assembly 3 passes through the base 21 and is rotatably connected to the base 21 . The other end of the driving assembly 3 is threadedly connected to the upper support assembly 4 .

[0034] In the embodiment of the present application, the external mains electricity supplies power to the driving component 3 in the device, thereby ensuring the normal operation of the device.

[0035] It should be noted that a control device (not shown in the figure) is provided on the base 1 described in this embodiment, and the pressure sensor 24 and the drive assembly 3 are respectively connected to the control device. Relevant technicians can achieve the purpose of operating this device by inputting preset data (for example: the pressure threshold measured by the pressure sensor 24) into the control device.

[0036] Specifically, during the pressure test of a batch of single hydraulic props, at this time, refer to Figure 2 , the support block 23 is in an inclined state, and the relevant technicians place one end of the single hydraulic support to be tested inside the second groove 231, and then push the other end of the single hydraulic support to be tested, and the support block 23 and the single hydraulic support rotate together.

[0037] The limiting rod 22 slides along the guide groove 232, and the support block 23 enters the inside of the first groove 212. The single hydraulic support to be tested remains upright, and the drive assembly 3 is started by the control device. The drive assembly 3 drives the upper support assembly 4 to move downward, and the upper support assembly 4 applies a force to the single hydraulic support. The pressure sensor 24 monitors the force at the bottom of the single hydraulic support. When the force reaches the preset value, the drive assembly 3 stops running and then enters the pressure holding stage.

[0038] If the pressure sensor 24 detects a change in the pressure value during the pressure holding stage, it indicates that the pressure resistance of the single hydraulic support is good and can be used normally. Otherwise, it indicates that the pressure resistance of the single hydraulic support is poor and requires subsequent maintenance.

[0039] After the pressure holding is completed, the driving component 3 drives the upper support component 4 to reset. The relevant technician pulls one end of the single hydraulic support. Under the action of the friction between the rubber ring 233 and the single hydraulic support, the support block 23 is disengaged from the first groove 212. The relevant technician continues to pull the single hydraulic support until it is disengaged from the second groove 231. Repeat the above steps. The relevant technician can continuously perform pressure resistance tests on multiple single hydraulic supports. The above connection process is easy to operate, thereby improving the detection efficiency of the single hydraulic support.

[0040] In one embodiment of the present application, Figure 2 As shown, the driving assembly 3 includes a driving device 31 , a linkage gear 32 and two screws 33 .

[0042] In one embodiment of the present application, Figure 5 As shown, the upper support assembly 4 includes a plate body 41 , two clamping plates 42 and two first adjustment handles 43 .

[0043] The plate body 41 is threadedly connected to the screw rod 33 , the two clamping plates 42 are movably connected to the plate body 41 , and the two first adjustment handles 43 are respectively mounted on the two clamping plates 42 .

[0044] It should be noted that the two card plates 42 described in this embodiment are movably connected to the plate body 41 by means of a slide groove and a slider. The slide groove is opened on the plate body 41, and a slider is provided on the card plate 42. The slider slides inside the slide groove.

[0045] Specifically, before testing the single hydraulic support, the two first adjustment handles 43 are rotated according to the size data of the end of the single hydraulic support, so that the two clamping plates 42 move relative to each other, and the distance between the two clamping plates 42 is slightly larger than the size of the end of the single hydraulic support.

[0046] It is understandable that, during the pressure test, the two clamping plates 42 can serve to limit the ends of the single hydraulic support.

[0047] During the operation of the drive assembly 3, the drive device 31 drives the two screws 33 to rotate through the linkage gear 32. The two screws 33 are threadedly connected to the plate body 41, so that the plate body 41 applies force to the end of the single hydraulic support, thereby achieving the purpose of pressure resistance test.

[0048] In one embodiment of the present application, Figure 6 As shown, two auxiliary components 5 are further included. The two auxiliary components 5 are symmetrically arranged on the base 1 .

[0051] Among them, one end of the inserting plate 521 passes through the supporting plate 51, and the inserting plate 521 is slidingly connected to the supporting plate 51; the second adjusting handle 522 is threadedly connected to the inserting plate 521, one end of the second adjusting handle 522 is rotatably connected to the supporting plate 51, and the arc plate 523 is connected to one end of the inserting plate 521.

[0052] In one embodiment of the present application, Figure 6-Figure 8 As shown, the protection assembly 53 includes a C-shaped plate 531 , an auxiliary rod 532 and a spring 533 .

[0053] Among them, the C-shaped plate 531 is sleeved on the outside of the inserting plate 521, and the C-shaped plate 531 is slidably connected to the inserting plate 521. One end of the auxiliary rod 532 is connected to the C-shaped plate 531, and the other end of the auxiliary rod 532 passes through the supporting plate 51. The auxiliary rod 532 is slidably connected to the supporting plate 51, and the spring 533 is sleeved on the outside of the auxiliary rod 532.

[0054] Specifically, during the pressure test of the single hydraulic support, relevant technicians can rotate the two second adjustment handles 522, the second adjustment handles 522 are threadedly connected to the insert plate 521, the insert plate 521 is slidingly connected to the support plate 51, and the insert plate 521 pushes the two C-shaped plates 531 closer to each other, and the arc plate 523 first contacts the outer wall of the single hydraulic support, and then the spring 533 is compressed and deformed, and relative sliding occurs between the auxiliary rod 532 and the support plate 51 until the two C-shaped plates 531 contact each other, thereby protecting the outside of the single hydraulic support, preventing the single hydraulic support from detaching from the equipment during the pressure test, and improving the safety during the test.

[0055] In one embodiment of the present application, Figure 1 As shown, it also includes a plurality of guide rods 6 , one end of the guide rod 6 is connected to the base 21 , the other end of the guide rod 6 passes through the plate body 41 , and the guide rod 6 is slidably connected to the plate body 41 .

[0056] It is understandable that the guide rod 6 is provided to limit the plate body 41 during its movement, thereby ensuring the reliability of the device during operation.

[0057] In summary, in the single hydraulic support pressure test equipment of the embodiment of the present application, the support block can be tilted and placed above the first groove, one end of the single hydraulic support is inserted into the second groove opened on the support block, and the support block can be inserted into the first groove after moving along the limit rod, and the top of the single hydraulic support is clamped with the upper support assembly. The above connection process is easy to operate, thereby improving the detection efficiency of the single hydraulic support.
