Description

Technical Field

[0001] This utility model belongs to the field of component production technology, specifically relating to a truss-type plastering workstation. Background Technology

[0002] In tunnel engineering, tunnel segments are key support components, and their production quality and efficiency have a significant impact on project construction. In the traditional production process of concrete tunnel segments, the finishing process after the segment mold is poured is a critical step, and it still mainly relies on manual operation.

[0003] The existing manual slurrying process involves two workers using a pull plate to smooth the surface of the tunnel segment mold after the segment mold is poured. However, this method has obvious drawbacks.

[0004] On the one hand, workers continuously perform high-intensity pushing and pulling movements, which consumes a lot of physical strength and easily leads to fatigue, thus affecting the quality and efficiency of the plastering process. On the other hand, the segment production workshop generates a lot of noise and dust due to processes such as mixing and vibration. Workers working in this environment for a long time will face serious threats to their health. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0096] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0097] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0098] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0099] Example 1:

[0100] like Figure 1As shown, this embodiment discloses a truss-type finishing workstation, which can simulate manual finishing actions to finish the concrete surface of the mold after the segment mold is poured, thereby effectively reducing the intensity of manual labor, saving labor costs, and improving the working environment of workers. Its specific structure includes: a supporting truss 1, a connecting beam 2, a supporting vertical plate 3, a supporting vertical beam 4, a finishing machine head assembly 5, a front and rear rotating mechanism 6, a Y-axis translation mechanism 7, a Z-axis vertical translation mechanism 8, and an X-axis translation mechanism 9.

[0101] The support truss 1 is used to provide a stable support platform for the entire workstation, including two support beams 11, which are arranged in parallel and at intervals and are in the same horizontal plane.

[0102] The connecting beam 2 is disposed between the supporting beams 11 and its length direction is perpendicular to the supporting beams 11, and is used to provide installation positions for other components.

[0103] The support vertical plate 3 is set on one side of the support horizontal beam 11 and serves as the mounting carrier for other components.

[0104] The support beam 4 is located on the outside of the support vertical plate 3 and its length direction is perpendicular to the connecting crossbeam 2, and is used to provide an installation position for the grouting machine head assembly 5.

[0105] The smearing machine head assembly 5 is located at the bottom of the supporting vertical beam 4, and is the core component for performing the smearing operation.

[0106] For example, such as Figure 2 As shown, the grouting machine head assembly 5 includes:

[0107] Upper suspended beam;

[0108] The box is rectangular with an opening on the top and is positioned below the upper cantilever beam.

[0109] Multiple vertical rods are spaced apart inside the strip box, and their tops pass through the upper suspension beam and are connected to anti-detachment blocks;

[0110] Multiple vibrating motors are spaced apart inside the strip box to improve the quality of the troweling surface through vibration;

[0111] Multiple damping springs, constrained between the upper suspension beam and the strip box, are used to apply a certain preload force to the mold surface.

[0112] The front and rear rotation mechanism 6 is installed between the support vertical beam 4 and the finishing head assembly 5, which enables the finishing head assembly 5 to rotate back and forth, thereby adjusting the finishing angle to meet the finishing requirements of the arc-shaped surface.

[0113] The Y-axis translation mechanism 7 is installed between the connecting beam 2 and the supporting beam 11. It is used to drive the connecting beam 2 to perform translational movement in the Y-axis direction (the length direction of the supporting beam 11), thereby driving the smearing machine head assembly 5 to move in one dimension in the horizontal direction, thereby expanding the smearing operation range.

[0114] The Z-axis vertical movement mechanism 8 is installed between the support vertical plate 3 and the support vertical beam 4. It drives the support vertical beam 4 to move vertically in the Z-axis direction, thereby driving the finishing machine head assembly 5 to move together. This allows for precise control of the distance between the finishing machine head assembly 5 and the surface of the concrete component.

[0115] The X-axis translation mechanism 9 is installed between the connecting beam 2 and the supporting vertical plate 3. It is used to drive the supporting vertical plate 3 to perform translational movement in the X-axis direction (the length direction of the connecting beam 2), thereby driving the supporting vertical beam 4, the front and rear rotation mechanism 6 and the grouting machine head assembly 5 to move together.

[0116] The working principle of the above technical solution is as follows:

[0117] The Y-axis translation mechanism 7 drives the connecting beam 2 to move in the Y-axis direction, and then the supporting vertical plate 3, supporting vertical beam 4 and front and rear rotation mechanism 6 can sequentially drive the smearing machine head assembly 5 to move in the Y-axis direction together.

[0118] The X-axis translation mechanism 9 drives the support vertical plate 3 to move in the X-axis direction, and then the support vertical beam 4 and the front and rear rotation mechanism 6 can sequentially drive the grouting machine head assembly 5 to move in the X-axis direction together.

[0119] The Z-axis vertical movement mechanism 8 drives the support beam 4 to move in the Z-axis direction, and the front and rear rotation mechanism 6 can drive the grouting machine head assembly 5 to move in the Z-axis direction together.

[0120] The front and rear angles of the trowel head assembly 5 are adjusted by the front and rear rotation mechanism 6 to adapt to the troweling requirements of different shaped surfaces, and then the trowel head assembly 5 completes the troweling operation.

[0121] This invention, through the coordinated operation of the Y-axis translation mechanism 7, the Z-axis vertical translation mechanism 8, and the X-axis translation mechanism 9, as well as the angle adjustment of the front and rear rotation mechanism 6, can precisely move the finishing head assembly 5 to various positions on the surface of the tunnel segment mold. It can also flexibly adjust the finishing angle to adapt to the finishing needs of different shaped surfaces, thereby significantly reducing the intensity of manual labor, improving production efficiency, ensuring the stability and consistency of finishing quality, and reducing errors and safety hazards caused by manual operation. This provides strong support for the large-scale and standardized production of tunnel segments.

[0122] In this embodiment, as Figure 2As shown, to provide stable and accurate Y-axis movement capability, the Y-axis translation mechanism 7 is further designed, including: two transverse translation modules 71 and a rotation drive module 72.

[0123] Two transverse modules 71 are respectively located at both ends of the connecting beam 2. This ensures the smoothness and consistency of movement in the Y-axis direction through synchronous drive on both sides, avoiding structural deformation or motion error caused by asynchronous movement on both sides.

[0124] Specifically, such as Figure 2 As shown, the transverse module 71 includes:

[0125] The movable support plate 711 is installed at the end of the connecting beam 2 and serves as the mounting base for other components, providing a stable support platform.

[0126] The first rack 712 is mounted laterally on the support beam 11 to convert rotational motion into linear motion and provide a power transmission path for movement in the Y-axis direction.

[0127] The first gear 713 is rotatably mounted on the movable support plate 711 and meshes with the first rack 712, and is used to drive the movable support plate 711 to move linearly along the direction of the first rack 712.

[0128] Several first linear guides 714 are installed between the movable support plate 711 and the support beam 11 to provide guidance and support for movement, ensuring straightness and stability during movement and improving the accuracy and reliability of the motion.

[0129] The rotary drive module 72 is installed on the side of the support beam 11 away from the support vertical plate 3, thereby avoiding motion interference with other components and improving structural compactness.

[0130] Specifically, such as Figure 2 As shown, the rotary drive module 72 includes:

[0131] Transfer case 721 is used to distribute and transmit input power;

[0132] The first motor 722 is connected to the input end of the transfer case 721 and is used as a power source to provide rotational power to the rotary drive module 72.

[0133] Two drive shafts 723 are respectively arranged on both sides of the transfer case 721, and the output ends on both sides of the transfer case 721 are each connected to the adjacent first gear 713 through a drive shaft 723.

[0134] When translation along the Y-axis is required, the process is as follows:

[0135] The control system starts the first motor 722, which inputs power to the transfer case 721. The transfer case 721 distributes the power to the drive shafts 723 on both sides, and the drive shafts 723 drive the first gears 713 on both sides to rotate synchronously.

[0136] Since the first gear 713 meshes with the first rack 712, the rotational motion of the first gear 713 is converted into the linear motion of the movable support plate 711 along the direction of the first rack 712, which in turn drives the connecting beam 2 to translate in the Y-axis direction. At the same time, the first linear guide rail 714 provides precise guidance for the movement of the movable support plate 711, ensuring the straightness and stability of the movement.

[0137] Through the above settings, synchronous drive on both sides is achieved, ensuring the smoothness and consistency of movement in the Y-axis direction and avoiding structural deformation or motion error caused by asynchronous movement on both sides. Furthermore, the combination of rack and pinion transmission and the first linear guide 714 provides precise motion control, ensuring the positioning accuracy of the finishing head assembly 5 in the Y-axis direction and improving the finishing operation effect.

[0138] In this embodiment, as Figure 5 As shown, to achieve stable and precise lateral movement, the Z-axis vertical movement mechanism 8 is further designed, which includes:

[0139] The second rack 81 is vertically mounted on the support beam 4 and is used to convert rotational motion into linear motion, providing a power transmission path for movement in the Z-axis direction.

[0140] The second gear 82 is rotatably mounted on the support vertical plate 3 and meshes with the second rack 81 to drive the support vertical beam 4 to make vertical linear motion;

[0141] The second motor 83 is mounted on the support vertical plate 3 and is connected to the second gear 82 for transmission. It is used as a power source to drive the second gear 82 to rotate.

[0142] Several second linear guide rails 84 are installed between the support vertical plate 3 and the support vertical beam 4 to provide guidance for the vertical movement of the support vertical beam 4 and ensure straightness and stability during the movement.

[0143] When vertical movement along the Z-axis is required, the process is as follows:

[0144] The control system activates the second motor 83, which drives the second gear 82 to rotate. Since the second gear 82 meshes with the second rack 81, the rotational motion of the second gear 82 is converted into vertical linear motion of the support beam 4 along the direction of the second rack 81. Simultaneously, the second linear guide rail 84 provides precise guidance for the movement of the support beam 4, ensuring the straightness and stability of the movement.

[0145] The design of the Z-axis vertical movement mechanism 8 utilizes the coordinated operation of rack and pinion transmission and linear guide rail guidance to provide precise motion control, ensuring high positioning accuracy in the Z-axis direction and meeting high precision requirements. Furthermore, the second linear guide rail 84 effectively reduces friction and vibration, making the support beam 4 move smoothly and improving surface finish. The components are rationally laid out, with a compact structure and small footprint, facilitating integration and installation. Moreover, the components possess excellent strength and wear resistance, enabling them to withstand large loads and external forces, ensuring stable and reliable long-term use.

[0146] In this embodiment, as Figure 4 As shown, to achieve stable and precise X-axis movement, the X-axis translation mechanism 9 is further designed, which includes:

[0147] The third rack 91 is mounted laterally on the connecting beam 2 and is used to convert rotational motion into linear motion, providing a power transmission path for movement in the X-axis direction.

[0148] The third gear 92 is rotatably mounted on the support vertical plate 3 and meshes with the third rack 91, which is used to drive the support vertical plate 3 to move laterally.

[0149] The fourth motor 93 is mounted on the support vertical plate 3 and is connected to the third gear 92 for transmission. It is used as a power source to drive the third gear 92 to rotate.

[0150] Several third linear guides 94 are installed between the connecting beam 2 and the supporting vertical plate 3 to provide precise guidance for the lateral movement of the supporting vertical plate 3, ensuring straightness and stability during the movement.

[0151] When translation along the X-axis is required, the process is as follows:

[0152] The control system activates the fourth motor 93, which drives the third gear 92 to rotate. Since the third gear 92 meshes with the third rack 91, the rotational motion of the third gear 92 is converted into a lateral linear motion of the supporting vertical plate 3 along the direction of the third rack 91. Simultaneously, the third linear guide rail 94 provides precise guidance for the movement of the supporting vertical plate 3, ensuring the straightness and stability of the movement.

[0153] The design of the X-axis translation mechanism 9 mentioned above utilizes the coordinated operation of rack and pinion transmission and linear guide rail guidance to provide precise control for the movement of the supporting vertical plate 3 and connected components in the X-axis direction; it also effectively reduces friction and vibration through the third linear guide rail 94, making the movement of the supporting vertical plate 3 smooth; the layout of each component is reasonable, the structure is compact, it occupies little space, and it is easy to integrate and install; moreover, the components have good strength and wear resistance, can withstand large loads and external forces, and are stable and reliable in long-term use.

[0154] In this embodiment, as Figure 3As shown, to achieve stable and precise forward and backward rotation, the forward and backward rotation mechanism 6 is further designed, including:

[0155] The mounting base 61 serves as the mounting base for other components, providing a stable mounting position;

[0156] A rotating shaft 62 is arranged below the fixed base 61 and is used to drive the connecting base 64 and the components connected thereto to achieve forward and backward rotation.

[0157] Two side plates 63 are installed on both sides of the bottom of the fixed base 61 and are rotatably mounted on the rotating shaft 62 to provide support for the rotating shaft 62 and ensure its stable rotation.

[0158] Multiple connecting seats 64 are spaced apart and fixedly mounted on the rotating shaft 62 for connecting components that need to achieve forward and backward rotation, such as the smearing machine head assembly 5;

[0159] Driven gear 65 is fixedly mounted on rotating shaft 62 and is used to transmit the rotational power from the source to rotating shaft 62, thereby driving rotating shaft 62 to rotate.

[0160] The driving gear 66 meshes with the driven gear 65 and is used to transmit the rotational power of the third motor 67 to the driven gear 65.

[0161] The third motor 67 is mounted on a side plate 63 and is connected to the drive gear 66 for transmission, serving as a power source to provide power for rotational motion.

[0162] When forward and backward rotation is required, the working process is as follows:

[0163] The control system starts the third motor 67, which drives the drive gear 66 to rotate. Since the drive gear 66 meshes with the driven gear 65, it will drive the driven gear 65 to rotate. The driven gear 65 will drive the rotating shaft 62 to rotate together. The rotating shaft 62 drives the smearing machine head assembly 5 to rotate back and forth through the connecting seat 64.

[0164] The design of the aforementioned front and rear rotating mechanism 6 achieves efficient power transmission through a gear transmission structure, which can stably and accurately transmit power to the rotating shaft 62, ensuring the smoothness and accuracy of the rotational motion, and realizing precise control of the rotation angle and speed. Furthermore, the reasonable layout of each component makes the mechanism compact, occupies little space, and is easy to integrate and install, while also improving the rigidity and stability of the mechanism.

[0165] In this embodiment, the first linear guide rail 714, the second linear guide rail 84 and the third linear guide rail 94 are all composed of V-shaped rollers and V-shaped guide rails. The rolling friction of the rollers on the guide rail surface can replace the sliding friction to achieve low-resistance linear motion; however, it is not limited to this and is not specifically limited.

[0166] Example 2:

[0167] This embodiment discloses a truss-type plastering workstation, which differs from Embodiment 1 in that, Figure 6 As shown, it also includes: a left and right deflection mechanism 10, which is installed between the support beam 4 and the front and rear rotation mechanism 6, and is used to enable the smearing machine head assembly 5 to swing left and right through the front and rear rotation mechanism 6.

[0168] When the heights on both sides of the mold are inconsistent, the left and right deflection mechanism 10 can deflect the finishing head assembly 5 in the left and right directions, thereby flexibly adjusting the finishing angle. This allows the finishing head assembly 5 to better fit the sides of the molds with different heights, ensuring uniform and flat finishing, reducing finishing defects caused by height deviations, and significantly improving finishing quality. Moreover, its layout is compact and reasonable, achieving the left and right deflection function without affecting the normal operation of other mechanisms, thus ensuring the stability and coordination of the structure.

[0169] In this implementation, such as Figure 6 As shown, the left and right deflection mechanism 10 includes:

[0170] The top plate 101 is installed at the bottom of the support vertical beam 4 and serves as a connecting component to receive and transmit the force and movement transmitted from the support vertical beam 4, and to provide an installation base for other components.

[0171] The lower base plate 102 is arranged below the upper top plate 101 and installed on the front and rear rotating mechanism 6, serving to connect the front and rear rotating mechanism 6.

[0172] The swing connector 103 is located between the upper top plate 101 and the lower bottom plate 102, and is used to allow the upper top plate 101 and the lower bottom plate 102 to swing relative to each other within a certain range, thereby realizing the left and right deflection adjustment of the machine head.

[0173] Multiple springs 104 are constrained between the upper top plate 101 and the lower bottom plate 102, and are respectively arranged on the left and right sides of the swing connector 103. They play the role of buffering and resetting, absorbing part of the impact force during left and right deflection, reducing the vibration and wear of the mechanism, and helping the mechanism to return to the initial position after the deflection action is completed, so as to ensure the stability and repeatability of the mechanism.

[0174] Multiple limit rods 105 are located on the left and right sides of the bottom surface of the upper top plate 101 to limit the relative deflection angle and prevent excessive deflection from damaging the mechanism or affecting the accuracy of the troweling operation.

[0175] Multiple limiting blocks 106, corresponding to the limiting rods 105, are provided on the left and right sides of the top surface of the lower base plate 102 to support the limiting rods 105.

[0176] The design of the left and right deflection mechanism 10 described above can buffer and dampen shocks during the deflection process, reduce impact and vibration, make the deflection more stable, improve the stability and quality of the finishing operation, and precisely limit the deflection amplitude to prevent excessive deflection from damaging the mechanism or affecting the finishing accuracy. It ensures that the mechanism operates within a safe and reasonable range, and has a compact structure, occupies little space, is easy to integrate and install, and at the same time ensures the overall strength and stability of the mechanism.

[0177] Example 3:

[0178] This embodiment discloses a truss-type plastering workstation, which differs from Embodiment 1 in that, Figures 7-12 As shown, the X-axis translation mechanism 9 is installed between the front and rear rotation mechanism 6 and the smearing head assembly 5, so that it can directly drive the smearing head assembly 5 to move in the X-axis direction.

[0179] In this embodiment, as Figure 12 As shown, to achieve stable and precise lateral movement, the X-axis translation mechanism 9 is further designed, which includes:

[0180] The strip frame 9a, which is mounted on the drive end of the front and rear rotating mechanism 6, serves as a basic installation platform, while other components provide stable support and installation position;

[0181] A strip-shaped horizontal plate 9b is arranged below the strip-shaped frame 9a and installed on the grouting machine head assembly 5, serving to connect the grouting machine head assembly 5.

[0182] Several fourth linear guides 9c are installed between the strip frame 9a and the strip plate 9b to provide guidance and support for the lateral movement of the strip plate 9b, ensuring straightness and stability during the movement.

[0183] The linear drive component 9d is mounted on the strip frame 9a and is connected to the strip plate 9b for transmission. It is used to drive the strip plate 9b to perform linear motion. It can take various forms such as electric push rod, screw and nut pair, etc., and can be selected according to different operation requirements and precision requirements. It can accurately control the moving speed and displacement of the strip plate 9b and realize precise adjustment of displacement.

[0184] The above-mentioned design of the X-axis translation mechanism 9 utilizes the cooperation between the linear drive component 9d and the fourth linear guide rail 9c to precisely control the movement of the strip plate 9b in the X-axis direction, thereby achieving precise adjustment of the finishing machine head assembly 5. The fourth linear guide rail 9c provides reliable guiding support, ensuring smooth movement, reducing vibration, and improving finishing quality. Furthermore, the components are compact in structure, occupy little space, and are easy to integrate and install. It also ensures the overall strength and rigidity of the mechanism, enabling it to withstand large loads.

[0185] In this embodiment, the first linear guide 714, the second linear guide 84, the third linear guide 94 and the fourth linear guide 9c are all composed of guide rails and sliders, etc., but are not limited to these, and are not specifically limited.

[0186] In this embodiment, as Figure 10 and Figure 12 As shown, to improve the smoothness of power transmission and prevent external factors from interfering with and damaging the transmission components, the front and rear rotating mechanism 6 also includes:

[0187] A support shaft 68 is rotatably mounted between two side plates 63 and has a drive gear 66 fixedly mounted on it. One end of the drive shaft 68 is connected to a third motor 67 for transmission, which provides stable support for the drive gear 66.

[0188] Two baffles 69 are installed on the other two sides of the bottom of the fixed base 61, and together with the side plate 63, they enclose a space 6a, which serves to protect the internal transmission components.

[0189] Among them, the driving gear 66 and the driven gear 65 are paired together to form multiple gear sets, and the gear sets are distributed at intervals within the accommodating space 6a.

[0190] The above design, through the cooperation of multiple pairs of driving gears 66 and driven gears 65, ensures the smoothness and efficiency of power transmission. By forming the accommodating space 6a, it provides a safe working environment for the transmission components, greatly improving reliability and stability, and reducing maintenance and repair costs.

[0191] In this embodiment, as Figure 6 As shown, it also includes: a left and right deflection mechanism 10, which is installed between the X-axis translation mechanism 9 and the smearing machine head assembly 5, and is used to directly enable the smearing machine head assembly 5 to swing left and right.

[0192] Specifically, the left and right deflection mechanism 10 includes:

[0193] The swing connector 10a is located between the strip horizontal plate 9b and the smearing machine head assembly 5, and includes an upper support and a lower support hinged by a pin, which is used to make the smearing machine head assembly 5 swing left and right at a certain angle with the swing connector 10a as the center.

[0194] Multiple springs 10b are constrained between the strip plate 9b and the smearing machine head assembly 5, and are respectively arranged on the left and right sides of the swing connector 10a. They play a role in buffering and resetting, which can reduce the rigid collision between the two, and can automatically reset the smearing machine head assembly 5 through the rebound force.

[0195] Two guide blocks 10c are respectively installed on the left and right sides of the top of the smearing machine head assembly 5 to provide guidance for the swing of the smearing machine head assembly 5, ensuring that the smearing machine head assembly 5 moves along a predetermined trajectory during the swing and preventing deviation or shaking.

[0196] Two limit seats 10d are installed at the left and right ends of the strip plate 9b respectively, and form a vertical sliding fit with the adjacent guide block 10c, which can limit the swing amplitude and ensure the safe operation of the mechanism.

[0197] When left and right swaying is required, its working principle is as follows:

[0198] An external force causes the squeezing machine head assembly 5 to swing around the swing connector 10a. During the swing, one side of the spring 10b is compressed, while the other side is stretched, providing a buffering effect. Simultaneously, the guide block 10c slides vertically within the limit seat 10d, guiding the swing and ensuring the accuracy of the swing trajectory. Once the swing is complete and the external force is stopped, the elasticity of the spring 10b causes the squeezing machine head assembly 5 to automatically return to its initial position, while the limit seat 10d restricts the swing amplitude of the machine head, ensuring the safe operation of the mechanism.

[0199] The design of the left and right deflection mechanism 10 mentioned above enables the left and right swinging function of the smearing machine head assembly 5, which has the advantages of high flexibility, good stability, buffering and shock absorption, automatic reset and precise guidance.
