It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0026] Combination Figure 1 and Figure 2As shown, according to a specific embodiment of the present application, a U-shaped card extraction tool is provided.

[0027] Specifically, the U-shaped card extraction tool includes an extraction plate body 1, along the length direction of the extraction plate body 1, the edge profile line of one end of the extraction plate body 1 is an arc line, along the width direction of the extraction plate body 1, one side of the extraction plate body 1 is provided with an extraction card slot group 2, and the extraction card slot group 2 includes at least two extraction card slots 20 arranged at intervals along the length direction of the extraction plate body 1.

[0028] The technical solution of the present embodiment is applied, and the edge of the tool is designed with an arc, so that the tool can slide more easily at the high-pressure hose joint. At the same time, it can also convert more manpower into useful work, that is, the force for extracting the U-shaped clip is as close to the movement direction of the U-shaped clip as possible. The extraction plate 1 is provided with an extraction slot 20. First, it ensures that the U-shaped clip can slide to a suitable position in the bayonet during operation, which is more susceptible to prying force; second, at the moment of extraction, it ensures that the U-shaped clip does not jump around, and controls it in the tool bayonet to prevent injury and loss of the U-shaped clip. The U-shaped clip extraction tool of the present solution is applied to the disassembly operation of the high-pressure hose joint in the maintenance hydraulic system, and the U-shaped clip of the hose joint can be quickly disassembled, making the high-pressure hose joint more convenient and quick, thereby solving the problem of difficulty in disassembling the high-pressure hose joint when repairing the hydraulic system in the prior art.

[0029] In this embodiment, the edge profile of the extraction plate body 1 is an arc line convex outward.

[0030] Furthermore, the extraction plate body 1 includes a first component section 11 and a second component section 12, wherein the first end of the second component section 12 is connected to one end of the first component section 11, and the edge profile of the second end of the second component section 12 is an arc; and one of the extraction slots 20 is provided on the first component section 11. Setting the edge profile of the second end of the second component section 12 as an arc can prevent the second component section 12 of the extraction plate body 1 from squeezing and damaging the high-pressure hose when it contacts the high-pressure hose, and at the same time facilitates the U-shaped clip to slide to the extraction slot 20 for disassembly after contacting the arc-shaped second component section 12.

[0031] In one embodiment of the present application, Figure 1 As shown, along the length direction of the extraction plate body 1, an extraction card slot 20 is provided on the first component section 11 near one end of the second component section 12, and the end of the first component section 11 away from the second component section 12 is used as a hand-held end, which can save effort and be more convenient when performing U-shaped card extraction according to the lever principle. Along the width direction of the extraction plate body 1, a side away from the extraction card slot group 2 can be marked with a scale to measure the precise size in daily maintenance work.

[0032] It should be noted that the first assembly section 11 and the second assembly section 12 are integrally formed at the connection point, so as to improve the structural strength and durability of the extraction plate body 1 and to increase the service life of the extraction plate body 1 .

[0033] Optionally, another extraction slot 20 is provided in the first assembly section 11. In this way, two extraction slots 20 are provided on the first assembly section 11, and the processing of the two extraction slots 20 can be completed simultaneously during the processing of the first assembly section 11, making the processing process more convenient.

[0034] Optionally, another extraction slot 20 is provided on the second assembly section 12. The two extraction slots 20 are respectively provided on the first assembly section 11 and the second assembly section 12, so that the extraction slot 20 can be closer to the end of the second assembly section 12, thereby making it easier for the U-shaped card to slide into the extraction slot 20 during processing.

[0035] In this embodiment, the two extraction card slots 20 are arranged at a certain distance along the length direction of the extraction plate body 1, which can facilitate the continuous card extraction operation of the U-shaped clip on the high-pressure hose. A more suitable extraction plate body 1 can be selected for card extraction operation according to the different location environments of the U-shaped card, so as to make the card extraction operation faster.

[0036] Preferably, if Figure 1 As shown, part of the other extraction slot 20 is opened on the first component section 11, and another part of the other extraction slot 20 is opened on the second component section 12. In this way, when the extraction slot 20 is used for work, the squeezing force on the first component section 11 and the second component section 12 can be reduced to a minimum, the force used for operation is reduced to a minimum, the use is more convenient, and the service life of the extraction plate body 1 is increased.

[0037] Furthermore, along the width direction of the extraction plate body 1, the length of the first group segment 11 is smaller than the length of the second group segment 12. Figure 1 As shown, along the width direction of the extraction plate body 1, away from the side where the extraction card slot 20 is provided, a stepped boss structure is formed at the connection between the first component segment 11 and the second component segment 12. In the length direction of the boss structure toward the extraction plate body 1, the boss structure can be used to abut when measuring the object to be measured, that is, as one end of the object to be measured to start measurement and counting. At the same time, the protruding step shape makes the extraction plate body 1 more convenient to carry and is not easy to fall off from the tool bag or pocket.

[0038] In one embodiment of the present application, Figure 1As shown, a stepped boss structure is formed at the connection between the first component segment 11 and the second component segment 12. In the width direction of the boss structure toward the extraction plate body 1, the boss structure forms a small hammer structure, which can be used to knock on the U-shaped clip or other small metal parts, so that it is convenient to extract the U-shaped clip after it is loosened. It should be noted that the thickness of the stepped boss structure formed at the connection between the first component segment 11 and the second component segment 12 can be set to be greater than or equal to the thickness of other parts of the extraction plate body 1 according to the size of the U-shaped clip, so as to facilitate the function of the small hammer.

[0039] Furthermore, along the width direction of the extraction plate body 1, the first side of the first component section 11 is arranged flush with the first side of the second component section 12, and an extraction card slot group 2 is provided on the plane where the first side of the first component section 11 is located. This arrangement facilitates the use of the extraction card slot 20 on the extraction card slot group 2, and at the same time facilitates the carrying and storage of the extraction plate body 1, and is not easy to be damaged, fall-resistant, and not easy to deform.

[0040] Furthermore, projected along the thickness direction of the extraction plate body 1, the extraction slot 20 includes a first slot section 21 and a second slot section 22 connected in sequence, the first slot section 21 and the second slot section 22 are arranged in communication with the opening of the extraction slot 20, and the second slot section 22 is arranged to protrude toward the side where the first slot section 21 is located, so that a step surface 220 is formed between the first slot section 21 and the second slot section 22. When the extraction slot 20 extracts the U-shaped clip, the step surface 220 at the opening where the second slot section 22 is connected to the extraction slot 20 extends into the U-shaped or annular surface of the U-shaped clip, and the opening where the first slot section 21 is connected to the extraction slot 20 abuts against the pipeline surface as a supporting point of the lever, and the step surface 220 bears the pressure of the U-shaped clip, and the first component section 11 moves upward to drive the step surface 220 to move upward, thereby removing the U-shaped clip.

[0041] Specifically, the first slot section 21 includes an arcuate slot section 211 and a straight slot section 212. The first end of the arcuate slot section 211 is connected to the opening of the extraction slot 20, the first end of the straight slot section 212 is connected to the second end of the arcuate slot section 211, the second end of the straight slot section 212 is connected to the second slot section 22, and a step surface 220 is formed between the straight slot section 212 and the second slot section 22. In one embodiment of the present application, the straight slot section 212 of the first slot section 21 is connected to the second slot section 22 to form a step surface 220. When the U-shaped clip is extracted, the support force provided by the step surface 220 to the U-shaped clip is provided by the straight slot section 212 and the second slot section 22. Setting the straight slot section 212 to a straight line can increase the stress area of ​​the step surface 220 providing the support force to the U-shaped clip, reduce the pressure on the step surface 220, improve the reliability and tolerance of the step surface 220, and make it not easy to be damaged.

[0042] In another embodiment of the present application, Figure 2 As shown, the arcuate groove section 211 is connected with the opening of the extraction slot 20, and the arcuate groove section 211 opens the slot space of the extraction slot 20 into a circular ring, a semicircular ring or a fan-shaped space, that is, the opening of the extraction slot 20 adopts an inner circular opening type, and the connection between the first end of the arcuate groove section 211 and the opening end of the extraction slot 20 is hook-shaped, which is convenient for the U-shaped clip to slide to a suitable position in the opening when disassembling, and is more susceptible to prying force. When the U-shaped clip is disassembled by the extraction plate 1, the U-shaped clip slides along the hook-shaped opening end into the circular ring, semicircular ring or fan-shaped space in the extraction slot 20, makes a circular motion and then stops, which can prevent the U-shaped clip from bouncing in an irregular direction at the moment of disassembly and extraction, resulting in the loss of the U-shaped clip or injury.

[0043] Specifically, the straight groove section 212 is extended along the width direction of the extraction plate body 1, and the second groove section 22 is protruded along the length direction of the extraction plate body 1. Such a setting can facilitate the conversion of manpower into useful work. At the same time, the edges of the first and second component sections 11 and 12 along the length direction or width direction of the extraction plate body 1 and the connection between the first and second component sections 11 and 12 are all designed with involute lines, so that the extraction plate body 1 can slide more easily at the high-pressure hose joint, so that the force of the extraction U-shaped clip and the movement direction of the U-shaped clip are adjusted to the same direction, that is, it is easy to make the U-shaped clip slide to the extraction card slot 20. Even if the extraction card slot 20 is not aligned with the U-shaped clip during operation, the extraction card slot 20 can be aligned with the U-shaped clip by sliding along the length direction of the extraction plate body 1, which is simple to operate, convenient to use and labor-saving.

[0044] In one embodiment of the present application, Figure 1 As shown, the arc of the end of the extraction plate body 1 is connected to the opening of one of the extraction slots 20. That is, a part of one of the extraction slots 20 is opened on the first side of the first component section 11, and the other part is opened on the first side of the second component section 12, which is convenient and efficient to use.

[0045] Furthermore, the thickness of the extraction plate body 1 is H, wherein 3.5mm≤H≤4.5mm. This arrangement enables the step-shaped boss structure formed at the connection between the first component segment 11 and the second component segment 12 to have a certain thickness, so that the boss structure forms a small hammer structure, which can be used to knock on the U-shaped clip or other small metal parts; the hook-shaped structure presented at the connection between the first end of the arc-shaped slot segment 211 and the open end of the extraction slot 20 has a certain thickness, and the reliability of the hook-shaped structure as a support point of the extraction plate body 1 is higher; the step surface 220 formed between the first slot segment 21 and the second slot segment 22 has a certain thickness, which can increase the stress area of ​​the step surface 220 providing support force to the U-shaped clip, reduce the pressure on the step surface 220, and improve the reliability of the step surface 220. At the same time, making the extraction plate body 1 have a certain thickness can also make the extraction plate body 1 less likely to deform during long-term use.

[0046] Preferably, the thickness of the extraction plate body 1 is H=4 mm. The extraction plate body 1 is made of steel plate. The material is easy to obtain and the structure is simple. It can be manufactured in a workshop in a short time, thereby improving work efficiency.

[0047] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0048] 1) The U-clip extraction tool not only has the function of quickly removing the U-clip of the high-pressure hose joint, but also has the functions of a ruler and a small hammer.

[0049] 2) The U-shaped card extraction tool is simple to operate, labor-saving, easy to carry, compact, drop-resistant, and not easy to deform, making it suitable for use by underground hydraulic support workers.

[0050] 3) The lever principle is adopted to save effort, and the involute design is adopted at the edge of the tool, so that the U-shaped card extraction tool can slide more easily at the high-pressure hose joint, and at the same time, more manpower can be converted into useful work, that is, the force for extracting the U-shaped clip is as close as possible to the direction of movement of the U-shaped clip; the tool mouth adopts an inner circular mouth type, firstly, to ensure that the U-shaped clip can slide to a suitable position in the extraction card slot 20 during operation, which is more susceptible to prying force, and secondly, at the moment of extracting the U-shaped clip, to ensure that the U-shaped clip will not jump around, and to control it in the extraction card slot 20 to prevent injury and loss of the U-shaped clip.

[0051] 4) The U-shaped card extraction tool is easy to carry and simple to make. The use of the U-shaped card extraction tool by hydraulic support workers during on-site operations can improve the safety factor and work efficiency of the operation.
