[0022] The present application also provides a method for using the position indicating device as described above, wherein the indicating plate is provided with scale lines, comprising:

[0023] Place the tank body into the through slot with the axial direction of the tank body extending along the extending direction of the first through slot until the tank body is supported on the reference surface of the mounting seat;

[0024] Connect indicating tools corresponding to the indicating signs at both ends of the tank body respectively;

[0025] The position of the tank body is adjusted until the difference between the scales of at least two indicating parts corresponding to the indicator plate meets the threshold range.

[0026] Advantageous effects provided by one or more embodiments of the present application:

[0027] When the cylindrical tank needs to adjust its position during installation and transportation, for example, when the tank needs to be leveled, the tank can be placed in the first through slot of the base and supported on the reference surface of the mounting base fixed to the base and located in the first through slot.

When at least two indicating signs are respectively fixed to the two ends of the side wall of the first through groove along the extension direction of the first through groove, the two ends of the tank body can be respectively installed with indicating tools corresponding to the indicating signs. According to whether the indicating part of the indicating tool points to the corresponding indicating sign and the specific position of the indicating part pointing to the corresponding indicating sign, the position of the two ends of the tank body can be judged, and whether the tank body is horizontal. The base, the mounting seat and the indicating sign are consistent with the overall reference. When the tank body is adjusted to the position where the indicating part corresponds to the indicating sign and the indicating part of the indicating tool at both ends of the tank body points to the indicating sign almost in the same position, it can be judged that the tank body has reached an almost leveled position. The measurement efficiency of the position of the tank body is fast, which is conducive to improving the installation and transportation efficiency of the tank body. When the reference is consistent, the position accuracy of the installation or transportation of the tank body will also be high, which solves the technical problems of the installation and transportation efficiency of the tank body and the installation and transportation position of the tank body to a certain extent.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] In the related art, if the tank body needs to be leveled, it is necessary to use tools to measure the distance between the horizontal marks at both ends of the tank body and the ground respectively, and to judge whether the tank body meets the leveling standard by comparing the distance between the horizontal marks at different positions of the tank body and the ground. Measuring the distance between the horizontal marks at different positions of the tank body and the ground, and then comparing the different distance parameters, takes a certain amount of time, affects the efficiency of adjusting the tank body into place, and ultimately affects the installation and transportation efficiency of the tank body. The flatness of the ground will also affect the accuracy of the measured distance between the horizontal mark of the tank body and the ground, thereby affecting the installation and transportation position accuracy of the tank body, and there are technical problems that the installation and transportation efficiency and installation and transportation position accuracy of the tank body are not ideal. The embodiment of the present application provides a position indication device and a method of use thereof, which can at least solve the above technical problems to a certain extent.

[0041] The present application will be described below with reference to the accompanying drawings:

[0042] Figure 1 FIG. 1 shows a schematic diagram of a position indicating device in use in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 1 The embodiment of the present application provides a position indicating device for indicating the position of a cylindrical tank body 10, comprising:

[0043] The base 1 is provided with a supporting surface 11 and a bottom surface 121 , and a first through slot 12 parallel to the supporting surface 11 . The first through slot 12 has two side walls 122 respectively connected to two sides of the bottom surface 121 .

[0044] The mounting seat 2 is fixed to the base 1 and is located in the first through slot 12 . A reference surface 21 parallel to the bottom surface 121 is provided on one side of the mounting seat 2 close to the opening of the first through slot 12 .

[0045] At least two indicator signs 3 are respectively fixed to two ends of the side wall 122 along the extending direction of the first through slot 12 .

[0046] The indicating tool 4 corresponding to the indicating sign 3 is used for connecting to the tank body 10 and is provided with an indicating portion 41 for pointing to the corresponding indicating sign 3 .

[0047] When the tank body 10 needs to adjust its position during installation and transportation, for example, when the tank body 10 needs to be leveled, the cylindrical tank body 10 can be placed in the first through slot 12 of the base 1 and supported on the reference surface 21 of the mounting seat 2 fixed to the base 1 and located in the first through slot 12. The reference surface 21 is arranged on the side of the mounting seat 2 close to the opening of the first through slot 12, which can support the tank body 10 and provide a reference for the tank body 10. The bottom surface 121 of the first through slot 12 is parallel to the support surface 11 provided on the base 1, and the reference surface 21 is parallel to the support surface 11. The support surface 11 and the reference surface 21 can be used as the position reference for the installation or transportation of the tank body 10, and can ensure that the reference of the tank body 10 during installation or transportation is relatively consistent. The axial direction of the tank body 10 can be extended along the extension direction of the first through groove 12. When the mounting seat 2 is located in the first through groove 12, both ends of part of the tank body 10 can extend out of the reference surface 21 of the mounting seat 2 and be respectively close to the two ends of the first through groove 12, providing installation space for the indicating tool 4. When at least two indicating signs 3 are respectively fixed to the two ends of the side wall 122 of the first through groove 12 along the extension direction of the first through groove 12, indicating tools 4 corresponding to the indicating signs 3 can be respectively installed at the two ends of the tank body 10. According to whether the indicating part 41 of the indicating tool 4 points to the corresponding indicating sign 3 and the specific position where the indicating part 41 points to the corresponding indicating sign 3, the position of the two ends of the tank body 10 can be judged, and whether the tank body 10 is horizontal can be judged. The base 1, the mounting base 2 and the indicator sign 3 have the same overall reference. The tank body 10 is adjusted to the point where the indicating part 41 corresponds to the indicator sign 3 and the indicating parts 41 of the indicating tools 4 at both ends of the tank body 10 point to the positions of the indicator sign 3 in an almost consistent manner. This allows the tank body 10 to be judged to have reached an almost leveled position. The measurement efficiency of the position of the tank body 10 is fast, which is beneficial to improving the installation and transportation efficiency of the tank body 10. Moreover, when the reference is consistent, the position accuracy of the installation or transportation of the tank body 10 will also be higher, which to a certain extent solves the technical problems of the installation and transportation efficiency of the tank body 10 and the installation and transportation position of the tank body 10 being not ideal.

[0048] Moreover, the base 1, the mounting seat 2 and the indicator sign 3 are an integral whole, and the relative positions of the base 1, the mounting seat 2 and the indicator sign 3 are accurately determined during the preparation process, so that the base 1, the mounting seat 2 and the indicator sign 3 as a whole have the same reference (for example, the support surface 11 of the base 1 is used as the reference). Therefore, for example, when a cylindrical tank body 10 is supported on the reference surface 21 of the mounting seat 2 and the axial direction of the tank body 10 extends along the direction of the first through groove 12 of the base 1, the two ends of the tank body 10 are connected to the indicating tool 4 corresponding to the indicator sign 3. According to the relative position relationship between the indicating part 41 of the indicating tool 4 and the corresponding indicator sign 3, it can be judged whether the tank body 10 is tilted and whether the position of the tank body 10 needs to be adjusted.

[0049] It should be noted that when the tank body 10 needs to be adjusted to a horizontal state, the base 1 is placed in a supported state with the reference plane 21 parallel to the horizontal plane, the tank body 10 is placed in the first through groove 12, and the tank body 10 is adjusted to an appropriate position with the aid of the indicating tool 4. After the tank body 10 is installed or transported, the tank body 10 can be separated from the mounting base 2. If it is necessary to adjust the tilt setting of the tank body 10, the position of the base 1 can be controlled to tilt the reference plane 21, and then the tank body 10 is placed in the first through groove 12, and the position of the tank body 10 can be adjusted with the aid of the indicating tool 4 and the sign 3. The position indicating device provided in the present application can indicate the position of the cylindrical tank body 10, and can also indicate the installation and transportation position of structures such as pipe fittings. For ease of understanding, a rotary structure similar to a cylinder is used for explanation below.

[0050] In some or certain embodiments, the first through slot 12 may be a rectangular through slot, and the mounting seat 2 may be a rectangular parallelepiped block whose length extends along the extending direction of the first through slot 12. This facilitates preparation.

[0051] In some or certain embodiments, the cross section of the first through slot 12 may also be an inverted trapezoid, and the mounting seat 2 may be a trapezoidal block whose length extends along the extension direction of the first through slot 12. The tank body 10 may also be supported, and leveling may also be achieved with the indicator plate 3 and the indicator tool 4.

[0052] In some or certain embodiments, the base 1 may include a bottom 13 and side portions 14 on both sides of the bottom 13, both of which are in the shape of a plate, the bottom 13 and the two side portions 14 enclose a first through groove 12, and a side of the bottom 13 away from the first through groove 12 may be a support surface 11. It is convenient to prepare, and it is also convenient to achieve leveling of the tank body 10 in conjunction with the indicator plate 3 and the indicator tool 4.

[0053] In some or certain embodiments, the mounting seat 2 may be located between the indicator plate 3 and the bottom surface 121 of the first through slot 12 , so as to facilitate observation of the corresponding relationship between the indicator plate 3 and the indicating portion 41 .

[0054] In some or certain embodiments, the mounting base 2 and the machine base may be connected by bolts or screws, etc., to facilitate assembly.

[0055] In some or certain embodiments, the sign 3 and the base 1 may be connected by fasteners such as bolts or screws.

[0056] In some or certain embodiments, both ends of each side wall 122 are provided with indicator signs 3 , and the indicator signs 3 corresponding to the two side walls 122 are relatively distributed.

[0057] In the extension direction of the first through slot 12, both ends of each side wall 122 are provided with indicator signs 3, and the indicator signs 3 corresponding to the two side walls 122 are relatively distributed, and each end of the tank body 10 can be connected to at least two indicator tools 4, and the indicating parts 41 of at least two indicator tools 4 at each end of the tank body 10 can respectively point to the opposite indicator signs 3 on the two side walls 122 of the first through slot 12. By comparing the positions indicated by the indicators of the indicator signs 3 at both ends on each side of the tank body 10 and pointing to the same side wall 122, it can be effectively judged whether the position of the tank body 10 is set within the allowable error range, thereby improving the accuracy of the installation or transportation position of the tank body 10.

[0058] In some or certain embodiments, the two indicator signs 3 respectively arranged at the two ends of the same side wall 122 have the same spacing from the reference surface 21. It is convenient to prepare, and the indicator signs 3 are arranged in this section. If the two indicator tools 4 located at the two ends of the tank body 10 and arranged on the same side of the tank body 10 indicate that the positions of the indicator signs 3 at the two ends of the same side wall 122 are the same, then the position of the tank body 10 is more reasonable, which is convenient for quickly judging whether the position of the tank body 10 is more accurate.

[0059] In some or certain embodiments, the base 1 may be a symmetrical structure, and the two side walls 122 of the first through groove 12 are respectively located on both sides of the symmetry plane of the base 1, and the mounting base 2 may also be symmetrical about the symmetry plane of the base 1, and an even number of indicator signs 3 are symmetrically distributed on both sides of the symmetry plane of the base 1. The symmetrical structure is easy to prepare, and it is also easy to judge the position of the tank body 10 by the status of the indicator tool 4 and the indicator sign 3.

[0060] Figure 2 A schematic diagram of the structure of a sign in some embodiments or certain embodiments of the present application is shown, with reference to Figure 2 In some or certain embodiments, the sign 3 is polygonal in shape, and a marking line 32 is provided on a indicating surface 31 of the sign 3 .

[0061] The sign 3 is polygonal in shape, and a scale line 32 is provided on the indicating surface 31 of the sign 3 to facilitate determining the position of the indicating portion 41 pointing to the sign 3 . The position of the tank body 10 can be adjusted according to the position of the indicating portion 41 .

[0062] It should be noted that the indication surface 31 of the indication sign 3 may be the surface with the largest area of ​​the indication sign 3 .

[0063] In some or certain embodiments, the sign 3 may be rectangular, and each side of the indicating surface 31 of the sign 3 may be engraved with a scale line 32, and the scale lines 32 of the four sides surround the center of the indicating surface 31, and the intersecting sides of the sign 3 may be transitioned by rounded corners. The scale lines 32 of the four sides can effectively reflect the position of the indicating portion 41, and know how to adjust the position of the tank body 10. The rectangular sign 3 with rounded corners on the side is also easy to install and reduces interference.

[0064] In some or certain embodiments, the indication surface 31 of the indication sign 3 may also be provided with an indication groove 33 or a marking point corresponding to the indication portion 41, and the indication groove 33 or the marking point may be surrounded by the scale lines 32 on the four sides of the indication sign 3. This can improve the corresponding effect between the indication sign 3 and the indication portion 41.

[0065] In some or certain embodiments, the indicator sign 3 may also be configured as a pentagon, and the indicating surface 31 of the indicator sign 3 may be provided with scale lines 32, which may also have an indicating effect.

[0066] It should be noted that, in the present application, the sign 3 is in a polygonal, rectangular or pentagonal shape, and the indicating surface 31 is in a polygonal, rectangular or pentagonal shape.

[0067] Figure 3 A schematic diagram of assembling an indicating tool and a tank body in some embodiments or certain embodiments of the present application is shown. Figure 4 A schematic diagram of a structure of an indicating tool in some embodiments or certain embodiments of the present application is shown, with reference to Figure 3 , 4 In some or some embodiments, the indicating means 4 comprises:

[0068] The arc-shaped positioning plate 42 has a positioning stop 421 on one side for cooperating with one end of the tank body 10, and at least two positioning through grooves 422 spaced from each other and connected to the positioning stop 421 are provided at one axial end of the arc-shaped positioning plate 42, and the indicator 41 is provided on the other side of the positioning piece.

[0069] The arc-shaped positioning plate 42 can be positioned with one end of the tank body 10 through the positioning stop 421. One end of the arc-shaped positioning plate 42 is provided with at least two positioning slots 422 spaced from each other, and the positioning slots 422 are connected to the positioning stop 421. Figure 3 As shown in the figure, for the tank body 10 with at least two ears 101 on the peripheral wall, the arc-shaped positioning plate 42 can be matched with one end of the tank body 10 through the positioning stop 421, and the positioning slot 422 can be sleeved on the corresponding ear 101. For example, when the tank body 10 needs to be adjusted to a horizontal level, the tank body 10 is placed horizontally, and the arc-shaped positioning plate 42 is matched with the tank body 10 through the positioning stop 421 and the positioning slot 422. The positioning slot 422 can be stuck on the ear 101 of the tank body 10 to complete the positioning of the arc-shaped positioning plate 42. The operation is simple. After the indicating tool 4 completes the positioning with the tank body 10, it can be judged whether the position of the tank body 10 is in place by the position relationship between the indicating part 41 and the indicating tool 4.

[0070] It should be noted that the number of the positioning slots 422 on the arc-shaped positioning plate 42 can be set according to the ears 101 actually provided on the tank body 10 . Figure 3Only the indicating tool 4 disposed at one end of the tank body 10 is illustrated, and the indicating tool 4 disposed at the other end of the tank body 10 is omitted.

[0071] In some or certain embodiments, the positioning stop 421 may include a plane that fits with one end of the tank body 10, and an arc-shaped curved surface connected to the plane and used to fit with the peripheral wall of the tank body 10. The positioning effect is good.

[0072] Figure 5 A partial structural diagram of an indicating tool in some embodiments or certain embodiments of the present application is shown, with reference to Figure 3 to Figure 5 In some or some embodiments, the indicating tool 4 further comprises:

[0073] The jacking rods 43 correspond to the positioning slots 422 one by one, and the jacking rods 43 are threadedly connected to the positioning member, and the jacking rods 43 can rotate relative to the positioning member to extend into the corresponding positioning slots 422.

[0074] The pressing rod 43, which is threadedly connected to the positioning member and inserted into the corresponding positioning slot 422, can rotate relative to the positioning member to move along its own axial direction, and can press the ear 101 to tighten the positioning member and the tank body 10. The stability of the indicating tool 4 can be improved, so as to improve the stability of the indicating part 41 pointing to the indicating sign 3, which is conducive to improving the accuracy of judging the position of the tank body 10.

[0075] In some or certain embodiments, the arc-shaped positioning plate 42 may be provided with two positioning slots 422, the two positioning slots 422 are spaced apart along the circumference of the arc-shaped positioning plate 42, two jacking rods 43 may be respectively threadedly connected to the two ends of the arc-shaped positioning plate 42 in the circumference, the indicating portion 41 may be located between the two positioning slots 422, and the jacking rod 43 may be a screw or a bolt, etc. It is convenient for operation, and the indicating portion 41 is also relatively stable.

[0076] In some or certain embodiments, the jacking rod 43 may also include a threaded rod portion 431 and a handle 432 pinned to one end of the threaded rod portion 431. This facilitates operation and overall assembly and disassembly.

[0077] In some or certain embodiments, the arc-shaped positioning plate 42 may include an arc-shaped plate body 423 and a cylindrical portion 424, the positioning stop 421 and the indicating portion 41 are respectively arranged on both radial sides of the arc-shaped plate body 423, and the positioning slot 422 is arranged at one axial end of the arc-shaped plate body 423. The arc-shaped plate body 423 is provided with connecting holes at both ends of its circumferential direction, and the connecting holes are connected to the corresponding positioning slots 422. The cylindrical portion 424 is coaxially inserted into the cylindrical portion 424, and the cylindrical portion 424 is connected to the arc-shaped plate body 423 by bolts or screws. The jacking rod 43 can extend into the cylindrical portion 424 and threadedly cooperate with the cylindrical portion 424. In this structure, the jacking rod 43 can rotate relative to the cylindrical portion 424 and can also enter the positioning slot 422 to press the lug 101. The cylindrical portion 424 is detachably connected to the arc-shaped plate body 423, and the cylindrical portion 424 can be replaced when excessively worn, which is conducive to extending the service life of the arc-shaped positioning plate 42.

[0078] In some or certain embodiments, the indicating tool 4 further comprises an elastic compression cap 44 sleeved on one end of the pressing rod 43 close to the positioning slot 422. The elastic compression cap 44 can play a protective role and improve the accuracy of the measurement of the tank body 10.

[0079] It should be noted that when the tension rod 43 moves relative to the arc-shaped positioning member, one end can extend into the positioning slot 422 , and the other end of the tension rod 43 is the end close to the positioning slot 422 .

[0080] In some or certain embodiments, the indicator portion 41 is a rotary structure, the indicator portion 41 is retractable along its own axis and one end is connected to the positioning member. The other end of the indicator portion 41 can be used to point to the indicator sign 3, and the correspondence and indication between the indicator portion 41 and the indicator sign 3 are more intuitive, which is convenient for determining the position of the tank body 10. The indicator portion 41 is retractable along its own axis and can be retracted according to the distance between the tank body 10 and the side wall 122 of the first through groove 12, and is more flexible to use.

[0081] In some or certain embodiments, the arc-shaped positioning plate 42 may further include a sleeve-shaped portion 425, which is threadedly connected to one side of the arc-shaped plate body 423, and the indicating portion 41 may be a telescopic needle, which can be telescopic along its own axis, and one end of which is detachably connected to the sleeve-shaped portion 425. After the telescopic needle is connected to the sleeve-shaped portion 425, it is convenient to connect to the arc-shaped plate body 423, so as to facilitate the disassembly and replacement of the telescopic needle.

[0082] It should be noted that, for the retractable indicating portion 41 , such as a retractable needle or a retractable rod, the working strokes of the retractable needle and the retractable rod are both set within the allowable error range of the tank body 10 .

[0083] In some or certain embodiments, the indicating tool 4 may also include a circular positioning member (not shown in the figure) and at least two fasteners (not shown in the figure), the circular positioning member is provided with an annular stopper matched with one end of the tank body 10, and the indicating portion 41 is provided on a side of the positioning member away from the annular stopper. At least two fasteners pass through the annular positioning member at intervals to abut against the peripheral wall of the tank body 10.

[0084] For a tank body 10 that is not provided with a support ear 101 or has a higher inherent safety, a circular ring positioning piece with an annular stop can also be used to cooperate with one end of the tank body 10, and then a fastener can be used to pass through the annular positioning piece to abut against the peripheral wall of the tank body 10. The annular positioning piece can also be positioned on the tank body 10 to facilitate the indicating part 41 on the annular positioning piece to point to the indicator sign 3.

[0085] Based on the same inventive concept, the present application also provides Figure 6 , Figure 6 A flowchart of a method for using a position indicating device in some embodiments or certain embodiments of the present application is shown, referring to Figure 6 The present application also provides a method for using the position indicating device as described above, wherein the indicator is provided with scale lines, including:

[0086] S101: inserting the can body into the through slot with the axial direction of the can body extending along the extension direction of the first through slot until the can body is supported on the reference surface of the mounting seat.

[0087] S102: Connect indicating tools corresponding to the indicating signs to the two ends of the tank body respectively.

[0088] S103: Adjust the position of the tank body until the difference between the scales of at least two indicator parts corresponding to the indicator signs meets the threshold range.

[0089] The structure of the position indicating device and its corresponding technical effects can be referred to above and will not be described in detail here. When determining the position of the tank body, the position of the tank body is adjusted until the difference between the scales of at least two indicating parts corresponding to the indicator signs meets the threshold range, which can provide a reference and ensure that the position of the tank body is adjusted relatively well.

[0090] In step S103 of some or certain embodiments, the position of the tank is adjusted so that the difference between the scales of the indicator signs corresponding to at least two indicating parts meets the threshold range, which can be achieved by adjusting the position of the tank so that the difference between the scales of the indicator signs pointed to by any two indicating parts meets the threshold range. This can effectively improve the accuracy of the installation or transportation position of the tank.

[0091] In some or certain embodiments, the threshold value may range from -10 mm to 10 mm, so as to ensure the accuracy of the installation or transportation position of the tank.
