[0026] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.
[0028] When using the Ray's clamp method to detect cement stability, the existing operating procedures usually require the operator to manually support the Ray's clamp to ensure that its position is stable during the cement slurry filling process. This practice is intended to prevent the specimen from leaking due to the movement of the Ray's clamp, thereby affecting the quality of the specimen and making it unable to meet the test requirements. However, relying on manual support of the Ray's clamp may lead to unstable support force. If the support force is insufficient, it may cause the Ray's clamp to move slightly, resulting in poor sealing of the specimen edge, thereby causing leakage. If the operator uses too much force during the support process, additional external force may be applied to the Ray's clamp, causing the Ray's clamp structure to undergo slight deformation, thereby affecting the accuracy of the stability results. Therefore, in order to solve the problems existing in the prior art, an embodiment of the present application provides a Ray's clamp fixing auxiliary tool to effectively fix the position of the Ray's clamp without subjecting the Ray's clamp to external forces, thereby ensuring the smooth progress of the cement slurry filling process, avoiding leakage of the specimen, and protecting the Ray's clamp from deformation, thereby ensuring the reliability of the test results.
[0029] Example 1
[0030] The embodiment of the present application provides a Lei's clamp fixing auxiliary tool, such as Figures 1 to 5 As shown, it includes: a bracket 1, the bracket 1 includes a pair of opposite side walls 101; a pair of clamping members 2, the pair of clamping members 2 are relatively arranged on the pair of side walls 101, and are respectively rotatably connected to the pair of side walls 101; the clamping members 2 include a first end 201 and a second end 202 relatively, and in a natural state, the distance between the first ends 201 of the pair of clamping members 2 is adapted to the outer diameter of the Lei clamp 9; a pair of connecting members 3, the pair of connecting members 3 are relatively arranged, and the two ends of each connecting member 3 are respectively connected to a clamping member 2 and a side wall 101, and the connecting member 3 is elastic.
[0031] The bracket 1 is composed of two opposite side walls 101. The side walls 101 are made of high-strength and high-stability materials such as metal and hard plastic to ensure that the bracket 1 has sufficient rigidity to resist small vibrations or external force interference during operation and provide a stable support foundation for the overall structure.
[0032] A pair of clamping members 2 are arranged on the side wall 101 opposite to each other, and are flexibly opened and closed by rotating connection. Each clamping member 2 has a first end 201 and a second end 202 opposite to each other. The first ends 201 of the two clamping members 2 are arranged facing each other. In a natural state, that is, when no external force is applied, the distance between the first ends 201 of the pair of clamping members 2 is adapted to the outer diameter of the Lei's clamp 9. When the Lei's clamp 9 is not clamped, the clamping member 2 is in an open state, and the distance between the first ends 201 thereof is just enough to accommodate the Lei's clamp 9, so that the Lei's clamp 9 is tightly surrounded by the pair of clamping members 2 but without obvious squeezing, thereby ensuring the stability of the Lei's clamp 9 during the process of filling cement slurry and avoiding deformation caused by clamping too tightly.
[0033] The two ends of the connecting member 3 are respectively connected to a clamping member 2 and a side wall 101. The connecting member 3 is elastic, so that in a static state, the first end 201 of the clamping member 2 contacts the outer surface of the Lei clamp 9 without obvious force. When the Lei clamp 9 moves slightly, causing the first ends 201 of a pair of clamping members 2 to open back to back, the connecting member 3 rebounds quickly with its elasticity, driving the clamping member 2 to return to the initial position, thereby applying a suitable clamping force to the Lei clamp 9.
[0034] The elasticity of the connecting member 3 may be derived from its own material properties, such as being made of elastic materials such as spring steel and rubber, or being achieved through components such as built-in springs and elastic films.
[0035] The Lei's clamp fixing auxiliary tool provided in the embodiment of the present application provides a stable foundation for the clamping member 2 through the bracket 1 and its side wall 101. A pair of clamping members 2 are installed on the side wall 101 by a rotating connection method, and can be opened and closed freely within a certain range. The first ends 201 of the pair of clamping members 2 are arranged facing each other, and the distance between them is precisely matched with the outer diameter of the Lei's clamp 9, so as to effectively fix the Lei's clamp 9 and avoid the uncertainty of manual support. The elasticity of the connecting member 3 enables the clamping member 2 to provide appropriate pressure when clamping the Lei's clamp 9, which not only ensures the stable fixation of the Lei's clamp 9, but also avoids the risk of deformation caused by excessive clamping.
[0036] In some embodiments, Figure 1 and Figure 3 As shown, the clamping member 2 is a rod structure, and the middle part of the clamping member 2 is rotatably connected to the side wall 101; the connecting member 3 is arranged along the length direction of the clamping member 2, one end of the connecting member 3 is connected to the side wall 101, and the other end is connected to the position of the clamping member 2 close to the second end 202.
[0037] The clamping member 2 is designed as a rod-shaped structure, and its main body is in the shape of a long strip. The cross-section can be selected in various forms such as round, square, polygonal, etc. to meet the clamping needs in different application scenarios. The middle part of the clamping member 2 and the side wall 101 are connected by rotation to achieve active cooperation, so that the first end 201 and the second end 202 of the clamping member 2 are distributed on both sides of the connection with the side wall 101. The clamping member 2 can rotate with the middle part as the axis to achieve the opening and closing action of the first end 201 and the second end 202. When a pair of first ends 201 move away from each other, the corresponding second ends 202 will move closer to each other, and vice versa, forming a reverse linkage relationship.
[0038] The connecting member 3 is arranged along the length direction of the clamping member 2 and maintains a parallel relationship with the clamping member 2. One end of the connecting member 3 can be directly and firmly connected to the side wall 101 by means of threaded connection, welding, bonding, plug-in, etc. to form a stable support structure. The other end of the connecting member 3 is connected to the position of the clamping member 2 near the second end 202, and the above-mentioned various fixing means are also used to ensure that there is no looseness between the connecting member 3 and the clamping member 2, forming an effective force transmission path.
[0039] In practical applications, when the Ray's clamp 9 is impacted when filling cement paste, or is affected by external forces such as vibration during the test, the first ends 201 of the pair of clamping members 2 will be opened due to the external force. At this time, due to the elastic characteristics of the connecting member 3, the second ends 202 of the pair of clamping members 2 will move away from each other under the elastic action, automatically adjusting the clamping force of the first end 201, ensuring that the Ray's clamp 9 is always in a suitable clamping state, effectively resisting external disturbances, and improving the accuracy of the test results.
[0040] In some embodiments, the Ray's clamp fixing auxiliary tool further includes: a pair of rotating shafts 4 , the pair of rotating shafts 4 are relatively arranged on a pair of side walls 101 , and each clamping member 2 is rotatably connected to the side wall 101 via a rotating shaft 4 .
[0041] Specifically, a first through hole is provided on the surface of the side wall 101, and the rotating shaft 4 is installed perpendicular to the side wall 101, one end of which is embedded in the first through hole and fixedly connected to the side wall 101 to form a stable rotation fulcrum. The clamping member 2 is a rod-shaped structure, and a second through hole is opened in the middle. The other end of the rotating shaft 4 passes through the second through hole, and there is a clearance fit relationship between the two, allowing the clamping member 2 to rotate freely around the rotating shaft 4 as the center, realizing the opening and closing action of the first end 201 of the clamping member 2. In order to prevent the clamping member 2 from accidentally disengaging from the rotating shaft 4 during the rotation process, a protrusion is designed at one end of the rotating shaft 4 that cooperates with the clamping member 2, and its size is larger than the size of the second through hole, thereby forming an interference fit to ensure that the clamping member 2 and the rotating shaft 4 always maintain an effective connection.
[0042] In some embodiments, the bracket 1 is U-shaped, and the distance between the inner walls on both sides of the open end of the bracket 1 is greater than the distance between the inner walls on both sides of the connecting end of the bracket 1; the clamping member 2 is arranged on the inner wall surface of the bracket 1.
[0043] The bracket 1 is U-shaped as a whole, and is composed of an open end that is not connected to the top of a pair of side walls 101 and a connecting end that is connected to the bottom. The distance between the inner walls on both sides of the open end is greater than the distance between the inner walls on both sides of the connecting end, forming a gradual change from wide to narrow in the inner cavity. From the open end to the connecting end, the inner cavity of the bracket 1 gradually narrows, indicating that the side wall 101 is inclined and forms a certain angle with the horizontal plane. A pair of clamps 2 are parallel to the connecting ends of the bracket 1 and are respectively installed on the surfaces of a pair of side walls 101 facing each other. The inclined side walls 101 can provide support for the clamps 2 perpendicular to the surface of the side walls 101.
[0044] Since the clamping member 2 and the rotating shaft 4 are clearance-fitted, the clamping member 2 is allowed to rotate in a direction parallel to the surface of the side wall 101, and can also move in a direction perpendicular to the rotating shaft 4. When the clamping member 2 is subjected to external force during the process of filling cement slurry in the Lei clamp 9, its first end 201 can move in a direction perpendicular to the rotating shaft 4, that is, a pair of first ends 201 move away from each other. At this time, the inclined side wall 101 can provide effective support for the clamping member 2 perpendicular to the surface of the side wall 101, prevent the clamping member 2 from rotating too much, and ensure the stability of the clamping action. Therefore, when the Lei clamp 9 moves or expands, causing the clamping member 2 to rotate too much, the inclined side wall 101 can intervene in time to limit the clamping member 2 to prevent it from rotating excessively, thereby achieving precise control and stable clamping of the Lei clamp 9.
[0045] In some embodiments, Figure 1 and Figure 4 As shown, the Lei clamp fixing auxiliary tool also includes: a pair of limit members 5, which are respectively arranged on a pair of side walls 101, and each limit member 5 is arranged below the clamping member 2 along a direction parallel to the inner wall surface of the side wall 101, for supporting the clamping member 2.
[0046] A pair of limit members 5 are respectively fixed on a pair of side walls 101 to form a stable connection with the side walls 101. The limit member 5 can be in the form of a limit column, which is installed on the side wall 101 in a direction perpendicular to the inner wall surface of the side wall 101. The connection method between the limit member 5 and the side wall 101 can be threaded connection, welding, bonding, snap connection, etc., to ensure a firm connection between the limit member 5 and the side wall 101 and form a stable support point. The installation position of the limit member 5 should ensure that it is located below the clamp 2, in contact with the lower surface of the clamp 2 or maintain a certain gap. In order to achieve the normal opening and closing action of the clamp 2 without affecting it, and to provide effective support, so that a pair of clamps 2 remain in a horizontal state. Since the second through hole of the clamp 2 is in clearance with the rotating shaft 4, the limit member 5 can effectively restrict the range of motion of the clamp 2 to prevent the clamp 2 from rotating around the rotating shaft 4. The clamping member 2 can only move in a direction perpendicular to the axis of the rotating shaft 4, that is, the first ends 201 of a pair of clamping members 2 can open and close freely without rotating up and down.
[0047] In some embodiments, the clamp fixing auxiliary tool further includes: a pair of pads 6 , the pair of pads 6 are respectively disposed on a pair of side walls 101 , and each pad 6 is disposed between the clamping member 2 and the side wall 101 .
[0048] A pair of pads 6 are respectively mounted on a pair of side walls 101, and are located between the clamping member 2 and the side walls 101. This provides an additional isolation layer between the clamping member 2 and the side walls 101, avoiding direct contact between the two, and reducing the risk of wear of the clamping member 2 due to long-term friction.
[0049] Specifically, a third through hole is provided on the surface of the pad 6, so that the pad 6 can be tightly sleeved on the shaft 4. The inner diameter of the pad 6 is precisely matched with the outer diameter of the shaft 4, ensuring a stable connection between the pad 6 and the shaft 4, and preventing the pad 6 from loosening or falling off during use. The pad 6 can be made of standard parts such as flat washers.
[0050] In some embodiments, the connecting member 3 is an elastic steel wire, and the surface of the elastic steel wire abuts against the side of the pad 6 to support the elastic steel wire and the clamping member 2 in a parallel state.
[0051] The elastic steel wire has good elasticity and strength. The diameter and length of the elastic steel wire should be selected according to the actual needs of the equipment. It can deform when subjected to force and quickly return to its original shape after unloading. It is suitable for scenarios that require dynamic adjustment of the clamping force.
[0052] like Figure 1 and Figure 4 As shown, the pad 6 is circular, one end of the elastic steel wire is connected to the position of the clamp 2 near the second end 202, and the side wall 101 sets the connection point with the other end of the elastic steel wire below the pad 6. The other end of the elastic steel wire needs to bypass the pad 6 and then connect to the side wall 101. This arrangement allows a portion of the surface of the elastic steel wire to contact the circumferential side surface of the pad 6, so that the pad 6 can provide support for the elastic steel wire and keep it horizontally arranged with the clamp 2, that is, in the absence of external force, the elastic steel wire is in a straightened state.
[0053] When the first end 201 of the clamping member 2 rotates due to an external force, the second end 202 rotates in the opposite direction. During this process, the elastic steel wire is deformed and tightened. Thanks to the elastic properties of the elastic steel wire, the second end 202 can quickly return to its initial state, so that the first end 201 can effectively clamp the Lei clamp 9.
[0054] In some embodiments, the first end 201 of the clamping member 2 is arc-shaped to match the Lei clamp 9, and the surfaces of the first ends 201 of a pair of clamping members 2 facing each other are respectively provided with anti-slip patterns.
[0055] The first end 201 of the clamping member 2 is in an arc-shaped structure that matches the outer contour of the Lei clamp 9, aiming to increase the contact area, ensure that the clamping member 2 can fit closely with the Lei clamp 9, and improve the clamping stability. Anti-skid patterns, such as grooves, convex points, and wavy patterns, are provided on the surfaces of the first ends 201 of a pair of clamping members 2 on one side facing each other, so as to increase the friction coefficient of the contact surface with the Lei clamp 9 and prevent the Lei clamp 9 from sliding or detaching during the clamping process. The presence of the anti-skid patterns increases the friction resistance between the clamping member 2 and the Lei clamp 9, and can effectively prevent the Lei clamp 9 from sliding even under force or vibration conditions, ensuring its stable position in the clamped state, thereby improving the accuracy of the test results.
[0056] In some embodiments, the Ray's clamp fixing auxiliary tool further includes: a rubber sleeve 7 , and the second end 202 of each clamping member 2 is sleeved with a rubber sleeve 7 .
[0057] The second end 202 of each clamping member 2 is equipped with a rubber sleeve 7. The shape of the rubber sleeve 7 is adapted to the second end 202 of the clamping member 2, ensuring that it can be tightly wrapped around the outside of the clamping member 2 without looseness, thereby providing a good protective effect. The rubber sleeve 7 is made of a rubber material with elasticity and wear resistance, such as natural rubber, nitrile rubber, silicone rubber, etc. The rubber sleeve 7 can prevent the user from directly contacting the metal surface of the clamping member 2, avoiding scratches on the user's hand skin due to the sharp edge or cold hard material of the clamping member 2 during operation, thereby improving the ergonomic performance and safety of the tool.
[0058] In some embodiments, the Ray clamp fixation auxiliary tool further includes: a support base 8 having a support surface, the bracket 1 is disposed on the support surface, and the horizontal projection of the first ends 201 of the pair of clamping members 2 is located on the support surface.
[0059] like Figure 2 and Figure 5 As shown, the support base 8 has a support surface arranged in the horizontal direction, which is used to carry the entire Lei's clamp fixing auxiliary tool. The support base 8 is made of hard and wear-resistant materials, such as cast iron, steel, engineering plastics, etc., and has a certain weight to ensure that the tool remains stable during use and will not be displaced due to force or vibration. The bracket 1 is fixedly installed on the support surface of the support base 8, and can be firmly connected with the base by bolts, welding, bonding, etc., to ensure the stability of the entire auxiliary tool structure. A pair of clamps 2 are arranged parallel to the support surface, and the projection of the first end 201 of the pair of clamps 2 (i.e., the part in contact with the Lei's clamp 9) in the horizontal direction is completely located on the support surface. This means that no matter how the clamp 2 is rotated or adjusted, its first end 201 never exceeds the boundary of the base. Thereby ensuring that the Lei's clamp 9 can be kept within the support surface range even if it moves slightly during the placement process, and will not slip or deviate, ensuring the safety and accuracy of the test process.
[0060] The Lei clamp fixing auxiliary tool provided in the embodiment of the present application is rotatably connected to a pair of side walls 101 of the bracket 1 through a pair of clamping members 2. The first ends 201 of the pair of clamping members 2 are arranged facing each other, and the distance between them is precisely matched with the outer diameter of the Lei clamp 9, so as to achieve effective fixation of the Lei clamp 9, avoid the uncertainty of manual support, and improve the accuracy and consistency of clamping. The elastic characteristics of the connecting member 3 enable the clamping member 2 to provide appropriate pressure when clamping the Lei clamp 9, which not only ensures the firm fixation of the Lei clamp 9, but also avoids the risk of deformation caused by excessive clamping. This non-rigid contact method fully protects the original state of the Lei clamp 9 and ensures the accuracy of the test results.
[0061] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
