[0024] Refer to the following Figures 1 to 6 A pressure testing machine 10 for mining filling tests according to some embodiments of the present invention is described.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a pressure testing machine 10 for mining filling test according to some embodiments of the present invention includes: an outer cylinder 100, a first opening 110 is provided on the outer peripheral wall of the outer cylinder 100; a plug 200, the plug 200 is located at the first opening 110, and the plug 200 can move relative to the first opening 110; a hammer head 300, located in the outer cylinder 100; a matching structure 400, located in the outer cylinder 100, the matching structure 400 includes a baffle 410; a first driving member 500, which is provided in the outer cylinder 100, and the first driving member 500 is used to drive the matching structure 400 to move relative to the outer cylinder 100 to Switching between a first position and a second position; a distance sensor, which is arranged in the outer cylinder 100; when the matching structure 400 is in the first position, the baffle 410 is located between the plug 200 and the hammer head 300, and the hammer head 300 is used to hammer the baffle 410, so that a part of the plug 200 is extended out of the outer cylinder 100 through the first opening 110 through the baffle 410; when the matching structure 400 is in the second position, the baffle 410 is staggered with the plug 200; wherein the distance sensor is used to detect the retraction displacement of the plug 200 when the matching structure 400 is in the second position, so as to determine the compactness of the soil.

[0026] In this embodiment, the pressure testing machine 10 for mining filling test includes an outer cylinder 100 , a plug 200 , a hammer head 300 , a matching structure 400 , a distance sensor and a first driving member 500 .

[0027] The outer peripheral wall of the outer cylinder 100 is provided with a first opening 110. The plug 200 is located at the first opening 110. The hammer head 300, the matching structure 400 and the first driving member 500 are all located in the outer cylinder 100. The outer cylinder 100 has the function of protecting the hammer head 300, the matching structure 400 and the first driving member 500 located therein, so as to prevent external force from directly acting on the hammer head 300, the matching structure 400 and the first driving member 500.

[0028] The first driving member 500 is used to drive the matching structure 400 to move relative to the outer cylinder 100. Specifically, the first driving member 500 is used to drive the matching structure 400 to switch between the first position and the second position. The matching structure 400 includes a baffle 410. When the matching structure 400 is in the first position, the baffle 410 is located between the plug 200 and the hammer 300. When the matching structure 400 is in the second position, the baffle 410 is staggered with the plug 200, and the hammer 300 is opposite to the plug 200 and arranged at intervals.

[0029] When the pressure tester 10 for mining filling test is used for testing, the pressure tester 10 for mining filling test is placed in the hole to be tested, and the first driving member 500 drives the matching structure 400 to move to the first position, so that the baffle 410 is located between the plug 200 and the hammer 300, and then the baffle 410 is hammered by the hammer 300 to hammer the plug 200 through the baffle 410, so that the plug 200 extends out of the outer cylinder 100 through the first opening 110 and is hammered into the soil layer of the hole. After the length of the plug 200 extending out of the outer cylinder 100 reaches a set value, the first driving member 500 drives the matching structure 400 to move to the second position, so that the baffle 410 is pulled out of the plug 200 and the hammer 300, and the baffle 410 is staggered with the plug 200. At this time, there is a gap between the plug 200 and the hammer 300 due to the withdrawal of the baffle 410. After the baffle 410 is evacuated, the distance sensor detects the retreat displacement of the jack 200, and the compactness of the soil is determined by the detection data of the distance sensor, so as to finally determine the current situation of the soil layer.

[0030] Specifically, the higher the compactness of the soil, the smaller the retraction displacement of the plug 200. The worse the compactness of the soil, the greater the retraction displacement of the plug 200. In other words, the detection data of the distance sensor can accurately reflect the current situation of the soil layer, and can ensure the measurement accuracy of the pressure testing machine 10 for mining filling test.

[0031] The baffle plate 410 is processed by fine machining so that when the baffle plate 410 is withdrawn to be staggered with the plug 200 , the friction between the baffle plate 410 , the plug 200 and the hammer head 300 is reduced, and the resistance of the plug 200 and the hammer head 300 to the baffle plate 410 is reduced.

[0032] Specifically, the distance sensor is a laser distance sensor.

[0033] In some embodiments, there are multiple first openings 110 , plugs 200 , hammers 300 , distance sensors and baffles 410 . A plug 200 is provided at each first opening 110 , and each plug 200 cooperates with a hammer 300 , a distance sensor and a baffle 410 .

[0034] In this embodiment, a matching structure 400 of the outer cylinder 100 , the plug 200 , the hammer head 300 , the distance sensor and the baffle 410 is further defined.

[0035] There are multiple first openings 110, multiple plugs 200, multiple hammers 300, multiple baffles 410, and multiple distance sensors. A plug 200 is provided at each first opening 110. Each plug 200 cooperates with a hammer 300, a distance sensor, and a baffle 410.

[0036] In this way, when the pressure testing machine 10 for mining filling tests is working, multiple hammer heads 300 drive multiple plugs 200 to work simultaneously through multiple baffles 410, so that multiple plugs 200 can extend out of the outer cylinder 100 through multiple first openings 110 at the same time, and be simultaneously hammered into the soil layer of the hole, so as to measure the soil layer conditions of the hole from multiple directions and multiple positions at the same time, and can accurately reflect the current actual situation of the soil layer.

[0037] This setting can ensure the consistency of the measurement time of multiple jacks 200, can measure the data of the soil layer of the hole from multiple directions at the same time, and can truly reflect the current situation of the soil layer.

[0038] Of course, according to specific actual use requirements, some of the multiple plugs 200 can be operated. In other words, according to the conditions of the holes to be detected, the multiple plugs 200 are controlled to work in a targeted manner, while ensuring the measurement accuracy, the energy consumption of the product is reduced, and the diverse use requirements of users are met.

[0039] In some embodiments, Figure 1 As shown, the outer cylinder 100 includes a cylindrical section 120 , and the cylindrical section 120 is provided with a plurality of first openings 110 , and the plurality of first openings 110 are arranged at equal intervals around the axis of the cylindrical section 120 .

[0040] In this embodiment, the structure of the outer cylinder 100 is further defined.

[0041] The outer cylinder 100 includes a cylindrical section 120, and the cylindrical section 120 is provided with a plurality of first openings 110, that is, the cylindrical section 120 serves as a carrier for setting the plurality of first openings 110. The plurality of first openings 110 are arranged at equal intervals around the axis of the cylindrical section 120 to ensure the balance of measurement at different positions of the soil layer, which is conducive to improving the measurement accuracy and truly reflecting the current actual situation of the soil layer.

[0042] In some other embodiments, a portion of the plurality of first openings 110 are arranged at equal intervals around the axis of the cylindrical section 120 .

[0043] In some other embodiments, some of the plurality of first openings 110 are arranged at intervals along the axial direction of the cylindrical section 120 .

[0044] In some embodiments, Figure 3 and Figure 4As shown, the matching structure 400 includes: an annular shell 420, a baffle 410 movably connected to the annular shell 420, a part of the baffle 410 is located on the outside of the annular shell 420, the baffle 410 can move in the radial direction of the annular shell 420, and the first driving member 500 is used to drive the annular shell 420 to rotate, and the rotation of the annular shell 420 can drive the baffle 410 to rotate; the distance sensor is arranged on the annular shell 420, and when the matching structure 400 is in the second position, the sensing part of the distance sensor is opposite to the top head 200 and is arranged at intervals.

[0045] In this embodiment, the composition of the mating structure 400 is further defined.

[0046] The mating structure 400 includes an annular shell 420 , and a baffle 410 is movably connected to the annular shell 420 . A portion of the baffle 410 is located outside the annular shell 420 . The baffle 410 can move relative to the annular shell 420 . Specifically, the baffle 410 can move radially along the annular shell 420 .

[0047] The hammer head 300 hammers the baffle plate 410 , and the baffle plate 410 can move outward in the radial direction of the annular shell 420 to hammer the plug 200 through the baffle plate 410 , so that the plug 200 extends out of the outer cylinder 100 through the first opening 110 and is hammered into the soil layer of the hole.

[0048] After the testing of the pressure testing machine 10 for mining filling test is completed, the baffle 410 can move radially inwardly along the annular shell 420 to move to the initial position.

[0049] The pressure testing machine 10 for mining filling test includes a reset structure, and the reset structure is used to drive the baffle 410 to move radially inwardly along the annular shell 420 to an initial position.

[0050] The user manually drives the baffle 410 to move radially inwardly of the annular shell 420 to an initial position.

[0051] In addition, the distance sensor is arranged on the annular shell 420, and the first driving member 500 is used to drive the annular shell 420 to rotate. When the annular shell 420 rotates, the position relationship between the baffle 410 and the plug 200 can be adjusted, and the position relationship between the distance sensor and the plug 200 can also be adjusted, so that the baffle 410 can be located between the plug 200 and the hammer head 300. The baffle 410 can also be staggered with the plug 200, and when the matching structure 400 is in the second position, the sensing part of the distance sensor is opposite to the plug 200 and is arranged at intervals to ensure the ranging position of the distance sensor and the plug 200, and provide structural support for effectively detecting the retraction displacement of the plug 200.

[0052] In some embodiments, Figure 3 , Figure 4 , Figure 5and Figure 6 As shown, the matching structure 400 also includes: a gear ring 430, which is located in the annular shell 420, and the gear ring 430 can rotate relative to the annular shell 420. The inner peripheral wall of the gear ring 430 is provided with a first tooth portion 432, and the outer annular surface of the annular shell 420 is provided with a second opening 422; a gear 440, which is located in the annular shell 420; the baffle 410 includes a first plate body 412 and a second plate body 414, the first part of the first plate body 412 is located in the annular shell 420, and the first part of the first plate body 412 rests on the gear 440. At the top, along the circumference of the annular shell 420, the side wall of the first part of the first plate body 412 is provided with a second tooth portion 416, the gear 440 is meshed between the first tooth portion 432 and the second tooth portion 416, the second part of the first plate body 412 extends out of the annular shell 420 through the second opening 422, the second plate body 414 is located outside the annular shell 420, and the second plate body 414 is connected to the first plate body 412; when the matching structure 400 is in the first position, the second plate body 414 is located between the plug 200 and the hammer head 300.

[0053] In this embodiment, the composition of the mating structure 400 is further defined.

[0054] The mating structure 400 further includes a ring gear 430 and a gear 440 .

[0055] The ring gear 430 and the gear 440 are both located in the annular housing 420 , and the ring gear 430 is rotatable relative to the annular housing 420 .

[0056] The baffle 410 includes a first plate body 412 and a second plate body 414. The first plate body 412 and the second plate body 414 are connected. The first part of the first plate body 412 is located inside the annular shell 420, the second part of the first plate body 412 is located outside the annular shell 420, and the second plate body 414 is also located outside the annular shell 420. The first plate body 412 and the second plate body 414 are in an "L" shape.

[0057] The second plate 414 is used to cooperate with the plug 200 and the hammer 300. Specifically, when the cooperation structure 400 is in the first position, the second plate 414 is located between the plug 200 and the hammer 300. When the cooperation structure 400 is in the second position, the second plate 414 and the plug 200 are staggered.

[0058] The inner peripheral wall of the gear ring 430 is provided with a first tooth portion 432, the side wall of the first part of the first plate body 412 is provided with a second tooth portion 416, and the gear 440 is meshed between the first tooth portion 432 and the second tooth portion 416. That is to say, the annular shell 420, the gear ring 430, the gear 440 and the baffle 410 are configured as an iris structure. In this way, the use requirement of the baffle 410 moving relative to the annular shell 420 along the radial direction of the annular shell 420 can be met. Specifically, the first driving member 500 drives the annular shell 420 to rotate by a first angle, and the rotation of the annular shell 420 can drive the baffle 410 to move between the top head 200 and the hammer head 300. The hammer head 300 hammers the baffle 410, and the baffle 410 can move outward along the radial direction of the annular shell 420, and the baffle 410 moves to drive the gear ring 430 to rotate along the first direction through the gear 440.

[0059] Specifically, the first driving member 500 drives the annular shell 420 to rotate at a second angle. The rotation of the annular shell 420 can drive the baffle 410 to move in a direction away from the mandrel 200 , so that the baffle 410 and the mandrel 200 are staggered.

[0060] Specifically, the pressure testing machine 10 for mining filling test includes a reset structure, which can drive the baffle 410 to move radially inwardly of the annular shell 420, and the baffle 410 moves to drive the gear ring 430 to rotate in the second direction through the gear 440, and the first direction is opposite to the second direction. Alternatively, the user manually drives the baffle 410 to move radially inwardly of the annular shell 420 to the initial position.

[0061] The first tooth portion 432 is an annular tooth. When there are multiple baffles 410, there are also multiple gears 440, and each baffle 410 is matched with a gear 440. This arrangement can ensure the consistency of the extended length and retracted length of the multiple baffles 410.

[0062] Specifically, the rotation of the gear ring 430 can drive the rotation of the multiple gears 440, and the rotation of the multiple gears 440 can drive the movement of the multiple baffles 410. That is, as long as one hammer head 300 hits one baffle 410, the other baffles 410 will move accordingly. The gear ring 430 and the multiple gears 440 can integrate the multiple baffles 410 into a whole, and have a linkage relationship, so as to ensure the consistency of the extended length and retracted length of the multiple baffles 410.

[0063] In some embodiments, Figure 3 As shown, the first driving member 500 includes: a motor 510, which is connected to the inner surface of the outer cylinder 100 and has an output shaft; a bracket 520, the output shaft is connected to the bracket 520, and the bracket 520 is provided with a plurality of connecting plates 522, and the plurality of connecting plates 522 are arranged at intervals along the circumference of the annular shell 420, and each connecting plate 522 is connected to the inner annular surface of the annular shell 420.

[0064] In this embodiment, the structure of the first driving member 500 is further defined.

[0065] The first driving member 500 includes a motor 510 and a bracket 520. The motor 510 has an output shaft, and the output shaft of the motor 510 is connected to the bracket 520. The bracket 520 is connected to the annular shell 420. That is, the motor 510 drives the annular shell 420 to rotate through the bracket 520, so as to achieve the purpose of driving the matching structure 400 to switch between the first position and the second position.

[0066] Specifically, the bracket 520 includes a plurality of connecting plates 522, which are arranged at intervals along the circumference of the annular shell 420, and each connecting plate 522 is connected to the inner annular surface of the annular shell 420. This arrangement increases the contact area between the bracket 520 and the annular shell 420, and can ensure the balance of the force acting on the matching structure 400 when the motor 510 is working, so that the annular shell 420 can rotate effectively, and the annular shell 420 is prevented from tilting.

[0067] In addition, the plurality of connecting plates 522 are arranged at intervals along the circumference of the annular shell 420 , which is beneficial to reducing the material input of the bracket 520 , reducing the weight of the bracket 520 , and reducing the production cost of the bracket 520 .

[0068] In some embodiments, the plurality of connection plates 522 are arranged at equal intervals along the circumference of the annular shell 420 .

[0069] In this embodiment, the arrangement positions of the plurality of connection plates 522 are further defined.

[0070] The plurality of connecting plates 522 are arranged at equal intervals along the circumference of the annular shell 420. This arrangement enables the external force of the motor 510 to act evenly on different positions of the annular shell 420 when it is working, provides structural support for the effective rotation of the annular shell 420, and provides structural support for ensuring the cooperation of the plurality of baffles 410 and the plurality of mandrels 200 that are movably matched with the annular shell 420.

The annular shell 420, the gear ring 430, the gear 440 and the baffle 410 of the matching structure 400 are configured as an iris structure.

[0088] There are multiple baffles 410 and multiple plugs 200 , and each baffle 410 cooperates with one plug 200 .

[0089] The working process of the pressure tester 10 for mining filling test is as follows: First, the pressure tester 10 for mining filling test is placed in the hole to be tested. Then, the motor 510 drives the annular shell 420 to rotate by a first angle, and the rotation of the annular shell 420 can drive each baffle 410 to move between a plug 200 and a hammer 300. Then at least one hammer 300 works to directly hammer the corresponding baffle 410, and the hammered baffle 410 cooperates with the corresponding gear 440, and through the ring gear 430, multiple baffles 410 can simultaneously move outward along the radial direction of the annular shell 420, and the baffle 410 makes a part of the plug 200 push out of the outer cylinder 100 through the first opening 110 and be hammered into the soil layer of the hole. After the length of each plug 200 extending out of the outer cylinder 100 reaches the set value, the motor 510 is started to rotate the annular shell 420 to the second angle, and the annular shell 420 rotates to drive the multiple baffles 410 to be misaligned with the positions of the multiple plugs 200. The distance sensor detects the retraction displacement of the mandrel 200, and determines the compactness of the soil with the detection data of the distance sensor. After the operation is completed, the multiple baffles 410 can be driven to move radially inward along the annular shell 420 by the reset structure to reset the multiple baffles 410. The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
