Description

Technical Field

[0001] The present application relates to the technical field of pipe segment processing, and in particular to a pipe segment mold finishing positioning mechanism. Background Art

[0002] Shield segments play a crucial role in modern tunnel construction, and their surface smoothness directly impacts the integrity and aesthetics of tunnel structures. To ensure a smooth and even surface, the segments undergo a finishing process after forming. Traditional manual finishing is labor-intensive and difficult to ensure consistent finishing quality.

[0003] Currently commonly used automated finishing methods mainly include automated finishing robots and fixed finishing devices. Among them, automated finishing robots operate through pre-set paths and angles, while fixed finishing devices achieve automatic smoothing of the mold surface through mechanical structure design.

[0004] However, when the placement of shield segments is inaccurate or deviates, the use of existing automated finishing devices will significantly affect the finishing accuracy, resulting in uneven segment surfaces and reduced construction quality. Summary of the Invention

[0005] In order to improve the above-mentioned problems, the present application provides a segment mold finishing positioning mechanism.

[0006] The present application provides a segment mold surface positioning mechanism that adopts the following technical solutions:

[0007] A segment mold surface positioning mechanism comprises a base, wherein the base is provided with a guide rail; the mold is placed on the guide rail;

[0008] A pushing member is installed on the base, and the pushing direction is consistent with the extending direction of the guide rail, and is used to drive the mold to move along the guide rail;

[0009] A first limiting member is installed at one end of the base away from the pushing member and is located on the same straight line as the pushing member; when the pushing member pushes the mold toward the direction of the first limiting member and moves to the first limiting member, the first limiting member and the pushing member clamp and fix the mold.

[0010] By adopting the above technical solution, the shield segments are placed on the mold. In order to ensure that the shield segments can be accurately positioned when smoothing, the pusher is used to push the mold toward the direction of the first limit member. The mold is guided by the guide rail so that the moving trajectory is fixed and will not deviate. Until the mold moves to the first limit member, the first limit member and the pushing end of the pusher clamp the mold, so that the position of the mold is accurately fixed after it moves along the fixed path.

[0011] Optionally, two groups of guide rails are provided on the base, and the pushing member and the first limiting member are located between the two groups of guide rails.

[0012] By adopting the above technical solution, the two sets of guide rails can support both ends of the mold, so that both ends of the mold can be stably guided, further ensuring the accuracy of the guide path, and the push member and the first limit member are located between the two guide rails to provide protection for the push member and the first limit member.

[0013] Optionally, the pushing member and the first limiting member on the same straight line form a group, and at least two groups are provided on the base.

[0014] By adopting the above technical solution, at least two sets of pushing members and the first limiting member are provided, so that the force on the mold can be more evenly dispersed, so that the mold is subjected to force at multiple points, ensuring that the position of the mold is more stable when clamped and fixed.

[0015] Optionally, the base is further provided with a guide groove, and the pushing end of the pushing member and the first limiting member are both located in the guide groove.

[0016] By adopting the above technical solution, the guide groove is used to provide guidance and fixation for the pushing path of the pushing end of the pushing member, so that the pushing path of the pushing member remains stable.

[0017] Optionally, a second limiting member is provided at the pushing end of the pushing member.

[0018] By adopting the above technical solution, the pushing member can push the second limiting member to move toward the first limiting member, and at the same time cooperate with the first limiting member to clamp and fix. The second limiting member can be used to avoid the pushing end of the pushing member from rigidly contacting the mold, causing damage to the mold. The second limiting member is used for auxiliary limiting, making the limiting more stable.

[0019] Optionally, the first limiting member includes a fixed portion, a rotating portion and an abutting portion; the fixed portion is installed on the base, and the fixed portion is connected along the vertical direction; the rotating portion is connected to the inner wall of the fixed portion; the abutting portion is pivotally connected to the rotating portion, and the abutting portion has a semi-arc structure. When the abutting portion rotates, the outer arc surface of the abutting portion abuts against the mold, and the other end abuts against the base.

[0020] By adopting the above technical solution, when the semi-arc surface of the abutting part abuts against the mold, the abutting part rotates along the rotating part. Since the mold applies force to the abutting part of the semi-arc surface, the abutting part is tilted by the force until it rotates to the base, so that the semi-arc surface of the abutting part abuts against the mold surface and the other end abuts against the base, which can prevent the mold from continuing to move and realize the limiting effect. When the mold needs to be detached, it moves away from the abutting part, and the abutting part is reset according to the influence of gravity.

[0021] Optionally, the second limiting member further includes a limiting portion based on the structure of the first limiting member; the limiting portion is connected to the base, the fixed portion is located in the limiting portion, and the pushing end of the pushing member passes through the limiting portion and is connected to the fixed portion; a limiting frame is also provided on the top surface of the limiting portion, and the abutting portion abuts against the limiting frame; push grooves are also provided on both side walls of the limiting portion, and the rotating portion is slidably connected to the push grooves.

[0022] By adopting the above technical solution, when the pushing end of the pushing member drives the second limiting member to move toward the mold, the abutting part contacts the mold, and as the pushing end continues to push, the abutting part is flipped to the limiting frame, and the limiting frame is used to prevent the abutting part from continuing to rotate. The pushing end continues to apply a pushing force to make the fixed part, the abutting part and the mold move synchronously toward the first limiting member, and at the same time, the rotating part moves along the pushing groove. When it moves to the end of the pushing groove, the mold just abuts against the first limiting member, thereby completing precise positioning.

[0023] Optionally, the second limiting member further includes a positioning sensing portion, which is arranged on the outer wall of the limiting portion, and the sensing ends are located at both ends of the push groove.

[0024] By adopting the above technical solution, the positioning sensing part can be used to open and close the pusher through electrical signals, so that the positioning effect is more precise and the position of the mold being pushed and positioned is more accurate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The shield segment is placed on the mold. To ensure that the shield segment is accurately positioned during leveling, the mold is pushed toward the first limiter by a pusher. The mold is guided by the guide rail to keep the moving track fixed and prevent deviation. When the mold moves to the first limiter, the first limiter and the pushing end of the pusher clamp the mold, so that the mold is accurately fixed in position after moving along the fixed path.

[0027] 2. The two sets of guide rails can support both ends of the mold, providing stable guidance for both ends of the mold, further ensuring the accuracy of the guide path. The pusher and the first limiter are located between the two guide rails to provide protection for the pusher and the first limiter.

[0028] 3. Providing at least two sets of pushers and the first limiter can make the force on the mold more evenly distributed, so that the mold is subjected to force at multiple points, ensuring that the position of the mold is more stable when clamped;

[0029] 4. The guide groove is used to provide guidance and fixation for the pushing path of the pushing end of the pushing member, so that the pushing path of the pushing member remains stable. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0040] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0041] The embodiment of the present application discloses a segment mold finishing positioning mechanism.

[0042] A positioning mechanism for plastering a segment mold 3 is provided for positioning the shield segment mold 3. The shield segment is placed on the mold 3, and the position of the mold 3 is adjusted on the positioning mechanism, so that the positioning accuracy of the plastering robot is improved when plastering the shield segment.

[0043] refer to Figure 1 As shown, it includes a base 1, which is used to provide a placement space for the mold 3, and the plastering robot can perform plastering on the base 1. A guide rail 2 is provided on the base 1, and the mold 3 is placed on the guide rail 2. The shield segment is located on the mold 3. The mold 3 is provided with an inward concave structure, which can fit with the guide rail 2, so that the mold 3 can move along the guide rail 2 to ensure the consistency of the moving path and the accuracy of the moving position.

[0044] The pushing member 5 is used to apply a pushing force to the mold 3 so that the mold 3 can move along the guide rail 2. The pushing member 5 is specifically installed on the base 1, and the pushing direction is consistent with the extension direction of the guide rail 2, so that the mold 3 can be stably driven to move along the guide rail 2.

[0045] The pushing member 5 may be any driving structure such as an electric push rod, a pneumatic cylinder or an electric cylinder to provide a driving force to push the mold 3 so that the mold 3 can move along the length direction of the guide rail 2 .

[0046] The first limiting member 4 is installed on the end of the base 1 away from the pushing member 5 and is located on the same straight line as the pushing member 5, that is, the first limiting member 4 is located on the extension line of the pushing direction of the pushing member 5, so that the mold 3 can abut against the first limiting member 4 during the movement, and the position is accurate.

[0047] Specifically, the shield segment is placed on the mold 3. In order to ensure that the shield segment can be accurately positioned when smoothing, the pusher 5 is used to push the mold 3 toward the direction of the first limit member 4. The mold 3 is guided by the guide rail 2 so that the moving trajectory is fixed and will not deviate. Until the mold 3 moves to the first limit member 4, the first limit member 4 and the pushing end of the pusher 5 clamp the mold 3, so that the position of the mold 3 is accurately fixed after it moves along the fixed path.

[0048] For further reference, Figure 1 As shown, two sets of guide rails 2 are provided on the base 1, and the pusher 5 and the first limiter 4 are located between the two sets of guide rails 2. The two sets of guide rails 2 can support both ends of the mold 3, so that both ends of the mold 3 can obtain stable guiding effects, further ensuring the accuracy of the guide path, and the pusher 5 and the first limiter 4 are located between the two guide rails 2 to provide protection for the pusher 5 and the first limiter 4, reducing damage caused by collisions and the like.

[0049] Further, refer to Figure 1 As shown, the pushing member 5 and the first limiting member 4 on the same straight line form a group, and at least two groups are arranged on the base 1. The arrangement of at least two groups of pushing members 5 and the first limiting member 4 can make the force on the mold 3 more evenly dispersed, so that the mold 3 is subjected to force at multiple points, ensuring that the position of the mold 3 is more stable when clamped and fixed, and also ensuring that when the shield segment on the surface of the mold 3 is surfaced, the force on the shield segment will not affect the fixed clamping effect of the mold 3. This application takes two groups as an example.

[0050] Further, refer to Figure 1As shown, the base 1 is also provided with a guide groove 11, and the pushing end of the pushing member 5 and the first limiting member 4 are both located in the guide groove 11. The guide groove 11 is used to provide guidance and fixation for the pushing path of the pushing end of the pushing member 5, so that the pushing path of the pushing member 5 remains stable. At the same time, except for the pushing end and the limiting end, other parts of the pushing member 5 and the first limiting member 4 can be hidden in the guide groove 11, which provides protection while not interfering with the movement of the mold 3.

[0051] Furthermore, refer to Figure 2 As shown, the first limiting member 4 includes a fixing portion 41, a rotating portion 42 and an abutting portion 43; the fixing portion 41 is installed on the base 1, and the fixing portion 41 is connected along the vertical direction. The fixing portion 41 can adopt a fixing frame, and the installation direction of the fixing frame is open at the top and bottom.

[0052] The rotating part 42 is connected to the inner wall of the fixed part 41. The rotating part 42 can adopt a rotating shaft, and the connection method with the fixed part 41 can adopt a pivot connection or a fixed connection. When the pivot connection is adopted, two pivot openings are opened on the surface of the fixed part 41, and the two ends of the rotating shaft can be inserted into the two pivot openings and rotate along the pivot openings.

[0053] The abutting portion 43 is pivotally connected to the rotating portion 42. The abutting portion 43 has a semi-arc structure. The outer arc surface of the abutting portion 43 abuts against the mold 3. When the abutting portion 43 is pivotally connected to the rotating portion 42, the rotating portion 42 and the fixed portion 41 are fixedly connected, that is, the rotating portion 42 is fixedly installed on the fixed portion 41 and cannot rotate with it. A pivot opening is provided on the surface of the abutting portion 43, and the abutting portion 43 is pivotally connected to the rotating portion 42 through the pivot opening. Both methods are intended to enable the abutting portion 43 to rotate, and therefore both are applicable.

[0054] refer to Figure 3 As shown, the abutment portion 43 can adopt an abutment plate, and the abutment plate is in the shape of a semi-arc plate. Specifically, as shown in the figure, when the semi-arc surface of the abutment portion 43 abuts against the mold 3, the abutment portion 43 rotates along the rotating portion 42. Since the mold 3 applies force to the abutment portion 43 of the semi-arc surface, the abutment portion 43 is tilted by the force until it rotates to the base 1, so that the semi-arc surface of the abutment portion 43 abuts against the surface of the mold 3, and the other end abuts against the base 1, which can prevent the mold 3 from continuing to move and realize the limiting effect. When the mold 3 needs to be detached, it moves away from the abutment portion 43, and the abutment portion 43 is reset according to the influence of gravity.

[0055] In some embodiments, reference Figure 1As shown, the pushing end of the pushing member 5 is provided with a second limiting member 6, and the second limiting member 6 is located on the pushing end of the pushing member 5, so that the pushing member 5 can push the second limiting member 6 to move toward the first limiting member 4, and at the same time cooperate with the first limiting member 4 to clamp and fix. The second limiting member 6 can be used to avoid the pushing end of the pushing member 5 from rigidly contacting the mold 3, causing damage to the mold 3, and the second limiting member 6 is used for auxiliary limiting, so that the limiting is more stable.

[0056] Among them, reference Figure 4 As shown, the first limit member 4 and the second limit member 6 have basically the same structure, the difference is that, on the basis of the first limit member 4, the second limit member 6 also includes a limit portion 61; the limit portion 61 is connected to the base 1, the fixed portion 41 is located in the limit portion 61, and the pushing end of the pushing member 5 passes through the limit portion 61 and is connected to the fixed portion 41. The limit portion 61 can adopt a limit frame, and a limit frame 611 is also provided on the top surface of the limit frame. The fixed portion 41 is located in the limit frame and can slide along the limit frame under the pushing action of the pushing end. During the sliding process, the abutment portion 43 contacts and rotates with the mold 3. The front end of the abutment portion 43 abuts the mold 3, and the back side abuts the limit frame 611 as it rotates, so that the abutment portion 43 cannot continue to rotate, thereby pushing the mold 3 toward the first limit member 4.

[0057] The fixed part 41 is also provided with a push groove 612 on both side walls, and the rotating part 42 is slidably connected to the push groove 612. The width of the push groove 612 is the same as the diameter of the rotating part 42, and the groove walls at both ends of the push groove 612 are semi-spherical, so that the rotating part 42 can rotate along the groove walls at both ends of the push groove 612. At the same time, the rotating part 42 can also move along the push groove 612. The push groove 612 can limit the travel distance between the fixed part 41 and the abutting part 43. When it moves to the end of the push groove 612, the other side of the mold 3 just abuts the first limit member 4, thereby ensuring the accurate position of the mold 3.

[0058] Specifically, when the pushing end of the pushing member 5 drives the second limiting member 6 to move toward the mold 3, the abutment portion 43 contacts the mold 3. As the pushing end continues to push, the abutment portion 43 is flipped to the limiting frame 611. The limiting frame 611 is used to prevent the abutment portion 43 from continuing to rotate. The pushing end continues to apply a pushing force to make the fixed portion 41, the abutment portion 43 and the mold 3 move synchronously toward the first limiting member 4. At the same time, the rotating portion 42 moves along the pushing groove 612. When it moves to the end of the pushing groove 612, the mold 3 just abuts against the first limiting member 4, thereby completing precise positioning.

[0059] Among them, when the shield pipe segment on the surface of the mold 3 needs to be taken out, the pushing end drives the second limit member 6 to move away from the first limit member 4. The abutment portion 43 of the first limit member 4 and the second limit member 6 has a higher center of gravity of the semi-arc surface due to the pivot point of the rotating portion 42, so it is reset under the influence of gravity. The abutment portion 43 will reset and rotate back to the fixed portion 41, so that when the mold 3 is separated from the base 1, the abutment portion 43 will not stand up.

[0060] For further reference, Figure 4 As shown, the second limiting member 6 also includes a positioning sensing portion 62, which is arranged on the outer wall of the limiting portion 61, and the sensing end is located at both ends of the push groove 612. The positioning sensing portion 62 can adopt a pressure sensor. The sensing end of the pressure sensor is divided into two parts, which are respectively located at both ends of the push groove 612. After the rotating portion 42 extends out of the push groove 612, when it moves along the push groove 612, it can abut or contact the two ends of the pressure sensor, so that the pressure sensor senses the position of the rotating portion 42, thereby sending an electrical signal to the background controller, and the controller stops pushing the pusher 5.

[0061] The positioning sensing portion 62 can be used to open and close the pusher 5 through electrical signals, so that the positioning effect is more precise and the position of the mold 3 is more accurate.

[0062] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
