Description

Technical Field

[0001] This utility model relates to the field of solar thermal power generation technology, and more specifically, to a heliostat main beam processing and fixing fixture and a heliostat main beam processing device. Background Technology

[0002] In the field of solar thermal power generation, especially in tower-type solar thermal power generation technology, the heliostat main beam is one of its core structural components, responsible for supporting and guiding the reflector. The machining accuracy of the heliostat main beam directly affects the heliostat's ability and efficiency in concentrating sunlight; therefore, the drilling of the heliostat main beam requires high precision. However, in existing technologies, the drilling of the heliostat main beam typically employs a clamping and fixing method, such as clamping or pressing the heliostat main beam and fixing it to the machining platform using mechanical fixtures. This fixing method causes the heliostat main beam to vibrate during subsequent machining operations, and this vibration can severely affect the positional accuracy and diameter accuracy of the holes.

[0003] Furthermore, as a long component, the heliostat main beam will have certain errors in straightness, roundness, etc. during the manufacturing process. It is difficult to effectively fix the heliostat main beam in subsequent drilling and other processes using existing fixing equipment. The existing fixing method is prone to causing part of the heliostat main beam to be suspended, and the suspended part of the heliostat main beam is more likely to vibrate during the drilling process.

[0004] Therefore, it is urgent to study a heliostat main beam machining fixture and a heliostat main beam machining device to solve the above problems. Utility Model Content

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0053] Example 1

[0054] like Figure 1 As shown, this embodiment of the invention provides a heliostat main beam machining and fixing fixture, which includes a support part 10, a mounting base 20, and an adjustment mechanism 30. The support part 10 is disposed on the mounting base 20 and is configured to support and fix the heliostat main beam 01. The support part 10 includes a placement component and a fixing component, with the fixing component mounted on the placement component. The adjustment mechanism 30 is disposed between the mounting base 20 and the support part 10, and is used to adjust the relative position of the support part 10 and the mounting base 20.

[0055] By applying the technical solution of this utility model, this application solves the vibration problem that occurs during the processing of the heliostat main beam by coordinating the placement components and fixing components. It also addresses the issue of partial suspension when the straightness of the heliostat main beam 01 is low, providing stable support and fixation for the suspended portion of the heliostat main beam 01, reducing vibration during processing, and consequently reducing displacement caused by vibration. Through the adjustment function of the adjustment mechanism 30, the relative position of the support part 10 and the mounting base 20 can be quickly adjusted, thereby adjusting the support height of the support part 10 to adapt to heliostat main beams of different diameters. This improves the flexibility of the support part 10 and allows it to support heliostat main beams of different sizes, further reducing vibration during processing and improving processing stability.

[0056] The specific structure and processing method of the heliostat main beam 01 are not limited in this embodiment. In this embodiment, the heliostat main beam 01 is the load-bearing main beam of the heliostat, and the heliostat main beam 01 is specifically a circular tube structure. The above embodiment does not limit the fixing method of the fixing components; it can be clamping or pressing, etc. Of course, in other embodiments of this solution, the cross-section of the heliostat main beam 01 can also be rectangular, elliptical, polygonal, or irregular, etc., and can be specifically designed according to the actual use. This application does not impose excessive restrictions on the heliostat main beam 01.

[0057] In this embodiment, the fixing component is a magnetic structure used to magnetically attach and fix the heliostat main beam 01. A placement groove 101 is provided on the placement component, and at least a portion of the heliostat main beam 01 is located within the placement groove 101. This placement groove 101 can limit the heliostat main beam 01 to a certain extent, reducing the possibility of the heliostat main beam 01 slipping out of the placement groove 101. The magnetic structure is installed on the side wall of the placement groove 101, and / or, on the bottom wall of the placement groove 101. Compared to existing technologies where objects are easily deformed by pressing or clamping forces, this application uses magnetic attachment to fix the heliostat main beam 01 in its natural state, avoiding direct mechanical pressure from the fixing component on the heliostat main beam 01 and reducing the risk of deformation of the heliostat main beam 01 during processing.

[0058] It should also be noted that the placement component can be of any shape. The placement groove 101 provided on it is a space for accommodating part of the heliostat main beam 01. Of course, in other embodiments, the space for accommodating part of the heliostat main beam 01 is insufficient to form a groove-shaped structure. For example, the placement component is two independent components that hold the heliostat main beam 01 in place. In this case, the space between the two independent components that hold the heliostat main beam 01 cannot form a complete groove, but its function is still to accommodate the heliostat main beam 01. Therefore, the placement groove 101 in this application does not only refer to a groove-shaped structure, but rather to the space for accommodating the heliostat main beam 01.

[0059] It is understandable that the magnetic attraction structure is installed on the placement slot 101 at the point where the placement component contacts the heliostat main beam 01. When the heliostat main beam 01 contacts the side wall of the placement slot 101, the magnetic attraction structure is installed on the side wall of the placement slot 101; when the heliostat main beam 01 contacts the bottom wall of the placement slot 101, the magnetic attraction structure is installed on the bottom wall of the placement slot 101; when the heliostat main beam 01 can contact both the side wall and the bottom wall of the placement slot 101, the magnetic attraction structure can be installed on both the side wall and the bottom wall of the placement slot 101, depending on the actual working conditions.

[0060] Specifically, such as Figure 1 As shown, the placement component includes a flat plate 11 and two support plates 12. The flat plate 11 extends along a first direction, and the two support plates 12 are respectively disposed on both sides of the flat plate 11 along a second direction. The flat plate 11 and the two support plates 12 cooperate to form a placement groove 101. The distance between the first ends of the two support plates 12 is less than the distance between the second ends of the two support plates 12. The end of the support plate 12 closest to the flat plate 11 is the first end of the support plate 12, and the end of the support plate 12 furthest from the flat plate 11 is the second end of the support plate 12. The flat plate 11 and the two support plates 12 are fixedly connected. The side of the flat plate 11 furthest from the mounting base 20 forms the bottom wall of the placement groove 101, and the side of the support plate 12 facing the flat plate 11 forms the side wall of the placement groove 101. The placement groove 101 formed above not only provides stable support for the heliostat main beam 01, but also provides reliable positioning and limits the position of the heliostat main beam 01, preventing excessive positional displacement or falling of the heliostat main beam 01 on the support part 10, thus ensuring the stability of processing. Furthermore, the change in distance between the two support plates 12 allows the placement component to accommodate and fit more heliostat main beams of different diameters.

[0061] In this embodiment, the diameter of the heliostat main beam 01 is larger than the dimension of the plate 11 along the second direction. Thus, the heliostat main beam 01 will only contact the two support plates 12, which fix and limit its movement, further preventing movement of the heliostat main beam 01 within the placement component. Two magnetic suction structures are provided, each mounted on one of the two support plates 12.

[0062] In this application, the first direction and the second direction are located in the same plane and are perpendicular to each other. A third direction is also provided, which is perpendicular to both the first and second directions. Specifically, in this embodiment, the X-axis is the first direction, the Y-axis is the second direction, and the Z-axis is the third direction. Both the first and second directions are horizontal. The first direction is the axial direction of the heliostat main beam 01, and the third direction is vertical. The support 10, the adjustment mechanism 30, and the mounting base 20 are sequentially distributed along the third direction.

[0063] Specifically, such as Figure 1 As shown, the magnetic attraction structure includes at least one electromagnet 13, which is disposed on the support plate 12. When the magnetic attraction structure includes multiple electromagnets 13, the multiple electromagnets 13 are spaced apart on the support plate 12 along the first direction. Thus, multiple electromagnets 13 are disposed on both sides of the support plate 12, and the multiple electromagnets 13 can form a uniformly distributed magnetic field, providing a more stable adsorption and fixation for the heliostat main beam 01. Compared to a single electromagnet, this distributed electromagnet layout ensures that the heliostat main beam 01 is subjected to uniform magnetic force on both sides along the second direction within the placement slot 101. When the heliostat main beam 01 has manufacturing errors or an irregular structure, the above design allows the electromagnets 13 to at least partially adsorb and fix the heliostat main beam 01, avoiding problems of unstable fixation or insufficient adsorption force, and improving the stability of the heliostat main beam 01 during processing.

[0064] In this application, the number of electromagnets 13 on a single support plate 12 is not limited.

[0065] In this embodiment, three electromagnets 13 are spaced apart along the first direction on a single support plate 12. By arranging multiple electromagnets 13 spaced apart along the axial direction of the main beam, i.e. the extension direction, the contact area along the axial direction of the heliostat main beam 01 can be increased, thereby improving the adsorption and fixation effect.

[0066] Furthermore, the adjustment mechanism 30 includes a telescopic component with a connecting end and an adjusting end. The connecting end is connected to the support portion 10, and the adjusting end is connected to the mounting base 20. The adjusting end can move relative to the connecting end to adjust the distance between the support portion 10 and the mounting base 20. The adjustment function of the telescopic component allows the heliostat main beam machining fixture to adapt to heliostat main beams 01 of different sizes and shapes. During machining, the length of the telescopic component can be automatically or manually adjusted according to the actual dimensions of the heliostat main beam to ensure that the placement slot 101 can provide optimal support, further improving the accuracy tolerance of the heliostat main beam 01.

[0067] The telescopic component can be a cylinder, spring, hydraulic cylinder, or electric push rod, etc., and can be designed according to the actual situation.

[0068] Specifically, such as Figure 1 As shown, the mounting base 20 includes a support platform 22 with a through hole. The telescopic component includes a support rod 32 and an elastic element 33. The first end of the support rod 32 is connected to the support portion 10, and the second end of the support rod 32 is movably inserted into the through hole, forming an adjustment end. The elastic element 33 is sleeved on the outer periphery of the support rod 32 and located between the plate 11 and the mounting base 20. The end of the elastic element 33 near the plate 11 forms a connecting end. The end of the support rod 32 facing the support portion 10 is the first end of the support rod 32, and the end of the support rod 32 away from the support portion 10 is the second end of the support rod 32. The elastic element 33 is compressed under the gravity of the heliostat main beam 01, and the amount of compression adapts to the different straightness and roundness of the heliostat main beam 01. The elastic element 33 allows the support portion 10 to automatically adjust the support force according to the weight and shape of the heliostat main beam 01, giving the support portion 10 an adaptive adjustment capability. When the heliostat main beam is placed on the support part 10, the elastic element 33 is compressed under the weight of the heliostat main beam 01, automatically adjusting the distance between the support part 10 and the mounting base 20 to ensure that the heliostat main beam 01 is in the best support state and avoid deformation of the heliostat main beam 01 caused by direct hard contact.

[0069] In this embodiment, both the support rod 32 and the elastic element 33 extend in a third direction. The elastic element 33 is a spring, one end of which is connected to the side of the plate 11 facing the support platform 22, and the other end of which is not connected to other components.

[0070] In other embodiments, the two ends of the elastic member 33 may be connected to the plate 11 and the support platform 22 respectively, or one end of the elastic member 33 may be connected to the side of the support platform 22 facing the plate 11, and the other end may not be connected to other components.

[0071] The adjustment mechanism 30 also includes a locking part, which is located between the mounting base 20 and the adjustment end. The locking part has a first clamping end and a second clamping end, located on opposite sides of the support rod 32. The first and second clamping ends can move closer or further apart to clamp the support rod 32. When the position of the support part 10 needs adjustment, the locking part is unlocked, allowing free adjustment of the distance between the support part 10 and the mounting base 20. Upon completion of the adjustment, the locking part clamps the support rod 32 again, ensuring the stability of the support part 10's position during processing and achieving high-precision positioning of the heliostat main beam 01. Furthermore, the clamping action of the locking part effectively prevents the support rod 32 from shifting due to vibration or external forces, ensuring the stability of the relative position between the support part 10 and the heliostat main beam 01.

[0072] Specifically, such as Figure 1 As shown, there are four support rods 32 and four elastic elements 33. The four support rods 32 are symmetrically slidably arranged on the support platform 22, and the four elastic elements 33 are respectively sleeved on the outer periphery of the four support rods 32. Two of the support rods 32 are spaced apart along the first direction below one of the support plates 12, and the other two support rods 32 are spaced apart along the first direction below the other support plate 12. This increases the stability of the support plate 12 supporting the heliostat main beam 01, and also improves the stability of the adjustment mechanism 30 when adjusting the support plate 12. The locking part includes four protrusions 34 and a double-sided telescopic mechanism 35. Each protrusion 34 is respectively arranged on the outer side of the support platform 22 away from the support part 10. Specifically, the four protrusions 34 are symmetrically arranged on the edge of the support platform 22, and each protrusion 34 extends along the edge of the through hole and is located on one side of the corresponding support rod 32. The four protrusions 34 are respectively arranged one-to-one with the four support rods 32, and the protrusions 34 form the first clamping end. Along the second direction, two support rods 32 on one side form the first support rod group, and two support rods 32 on the other side form the second support rod group. A double-sided telescopic mechanism 35 is located on the side of the support platform 22 away from the support part 10, between the first and second support rod groups. The double-sided telescopic mechanism 35 includes a fixed section and two telescopic sections 351. The fixed section is drivenly connected to the two telescopic sections 351, which face the first and second support rod groups respectively. Any one of the telescopic sections 351 cooperates with two protrusions 34 on the same side to clamp and fix the two support rods 32 on the same side. The telescopic section 351 forms the second clamping end. The clamping method of the protrusions 34 and the telescopic sections 351 allows the telescopic sections 351 to avoid the support rods 32 when they move, reducing direct friction and wear on the support rods 32. This ensures smooth adjustment of the support rods 32 and extends the service life of the locking part and the entire heliostat main beam machining and fixing fixture.

[0073] Specifically, the double-sided telescopic mechanism 35 is a double-acting cylinder.

[0074] It should be noted that the double-sided telescopic mechanism 35 in this solution is not limited to a bidirectional telescopic mechanism; it can also be a double-sided telescopic mechanism 35 composed of two single-sided telescopic mechanisms, and the specific design can be tailored to the actual situation. Of course, the telescopic mechanism can be one or more combinations of components such as cylinders, hydraulic cylinders, and electric actuators.

[0075] Preferably, the structural contours of the ends of the protrusion 34 and the telescopic section 351 are adapted to the structural contours of the outer periphery of the support rod 32, which can increase the contact area between the locking part and the support rod 32, thereby improving the clamping and fixing effect of the locking part on the support rod 32.

[0076] Furthermore, the mounting base 20 also includes two mounting rods 21, which are spaced apart at the bottom of the support platform 22. The end of each mounting rod 21 away from the support platform 22 is used to connect to the processing device. The spacing between the two mounting rods 21 provides a stable support point for the processing device, ensuring a secure connection between the processing device and the mounting base 20.

[0077] In this embodiment, the mounting rod 21 is fixed to the processing device by fasteners, which facilitates disassembly, assembly, and repositioning.

[0078] Specifically, such as Figure 1 As shown, the heliostat main beam machining fixture also includes a housing 40. The housing 40 has an opening that corresponds to the placement slot 101. The housing 40 covers the support 10, mounting base 20, and adjustment mechanism 30, and is separately mounted from them. The end of the housing 40 furthest from the opening is connected to the machining device. The housing 40 provides physical protection for the support 10, mounting base 20, and adjustment mechanism 30, effectively isolating contaminants such as dust, cutting fluid, and metal shavings in the machining environment, protecting critical components from damage, and extending the service life of the components.

[0079] Specifically, the distance between the end of the opening closest to the mounting base 20 and the mounting base 20 is less than the distance between the placement groove 101 and the mounting base 20. When the spring is compressed to its limit, the outer shell 40 will not interfere with the heliostat main beam 01. This avoids interference between the opening and the placement groove 101 during position adjustment, thus preventing any impact on the support effect of the placement groove 101.

[0080] In other embodiments, the housing 40 may be fixedly connected to the support 10 and move together with the support 10. When the spring is compressed to its limit, the housing 40 will not interfere with the processing device.

[0081] Example 2

[0082] like Figure 2 and Figure 3 As shown, according to another embodiment of the present invention, a heliostat main beam processing device is provided. The heliostat main beam processing device includes a worktable 50, multiple support mechanisms 60, a positioning mechanism, and at least one heliostat main beam processing fixture 70. The worktable 50 extends along a first direction. The support mechanisms 60 are used to place the heliostat main beam 01 to be processed. The multiple support mechanisms 60 are spaced apart on the worktable 50 along the first axis direction, ensuring that the arrangement direction of the support mechanisms 60 is consistent with the axial direction of the heliostat main beam 01, thereby ensuring smooth and stable feeding and preventing the support mechanisms 60 from causing compression deformation to the heliostat main beam 01. The positioning mechanism is installed on the worktable 50 and is used to fix the relative position of the heliostat main beam 01 and the worktable 50. At least one heliostat main beam processing fixture 70 is arranged on the worktable 50 along the first axis direction. When there are multiple heliostat main beam processing fixtures 70, they are spaced apart on the worktable 50 along the first axis direction. At least a portion of the heliostat main beam 01 is located within the placement slot 101 of the heliostat main beam machining and fixing fixture 70, which is configured to fix the heliostat main beam 01. When a standard heliostat main beam 01 is fixed to the heliostat main beam machining device, the axis of the standard heliostat main beam 01 is the first axis. The heliostat main beam machining and fixing fixture 70 is the heliostat main beam machining and fixing fixture mentioned in the above embodiments. The heliostat main beam machining and fixing fixture 70 can provide stable support and fixation for the suspended portion of the heliostat main beam 01, reducing vibration of the heliostat main beam 01 during machining, thereby reducing positional displacement of the heliostat main beam 01 caused by vibration during machining, thus reducing deviations in the dimensional structure of the machined structure and improving machining accuracy.

[0083] It should be noted that the standard heliostat main beam 01 is a heliostat main beam that meets the preset requirements (i.e., a heliostat main beam whose straightness, roundness, and other data all meet the design values).

[0084] In this application, there is no limitation on the number and location of the heliostat main beam machining and fixing fixture 70. It can be set at the suspended position of the heliostat main beam 01 that is greatly affected by vibration or at the position where vibration reduction is required.

[0085] The positioning mechanism includes a first axial positioning structure 81, a second axial positioning structure 82, and a radial positioning structure 83. The first axial positioning structure 81 and the second axial positioning structure 82 are respectively spaced apart at both ends of the worktable 50 along a first direction. The first axial positioning structure 81 is a baffle mounted on one of the support mechanisms 60, and the second axial positioning structure 82 is a telescopic cylinder. When the heliostat main beam 01 is placed on multiple support mechanisms 60, one end of the heliostat main beam 01 abuts against the first axial positioning structure 81, and the second axial positioning structure 82 abuts against the other end of the heliostat main beam 01 to position the axial position of the heliostat main beam 01. The radial positioning structure 83 consists of two blocks spaced apart along a second direction, and the two blocks are spaced apart on the support mechanism 60. When the heliostat main beam 01 is placed on multiple support mechanisms 60, the two blocks can move closer or further apart to position the water level support 02 of the heliostat main beam 01 and adjust and fix the position of the heliostat main beam 01 along the second direction. The above structures are all existing technologies and will not be elaborated further here.

[0086] In this embodiment, the processing device is specifically a drilling machine, and also includes multiple drilling devices 90. The multiple drilling devices 90 are arranged on the worktable 50, and the drilling devices 90 are used to drill holes in the support seats 02 on the main beam 01 of the heliostat.

[0087] In other embodiments, the heliostat main beam 01 or the support beam 02 may also undergo other processing.

[0088] The operation flow of the processing device provided by this utility model is as follows: After the heliostat main beam 01 is loaded onto the support mechanism 60 and the heliostat main beam processing and fixing fixture 70, the second axial positioning structure 82 is first driven to abut against the end of the heliostat main beam 01, and cooperates with the first axial positioning structure 81 to achieve axial positioning of the heliostat main beam 01. Then, the second axial positioning structure 82 is released, and the radial positioning structure 83 abuts against the support beam seat 02 of the heliostat main beam 01. Then, the second axial positioning structure 82 is activated again to position the heliostat. After positioning the main beam 01 of the heliostat and ensuring that the placement slot 101 contacts the circular tube of the main beam 01, the double-sided telescopic mechanism 35 is activated to lock the position of the support rod 32. Then, the electromagnet 13 is activated to attract and fix the main beam 01. Multiple drilling devices 90 drill holes in the support beam seat 02. After processing, the electromagnet 13 is turned off, and the first axial positioning structure 81, the second axial positioning structure 82, and the two sets of radial positioning structures 83 are driven to simultaneously move away from the main beam 01. Finally, the main beam 01 is unloaded. The above settings assist in positioning the suspended part in the middle of the main beam 01 without affecting the normal positioning of other positioning structures of the drilling machine, thereby playing a vibration reduction role.

[0089] The technical solution provided in this application has the following beneficial effects:

[0090] 1. The straightness tolerance of the heliostat main beam 01 is high, which can ensure that the straightness of the heliostat main beam 01 meets the requirements and within a certain range. When loading, no matter which direction the heliostat main beam 01 bends, the heliostat main beam processing and fixing fixture 70 can adapt to the adjustment of the position to support and adsorb the heliostat main beam 01.

[0091] 2. No force is applied to the heliostat main beam 01 during the support and adsorption process, which would cause the heliostat main beam 01 to deform and remain in its natural position. This prevents the heliostat main beam 01 from deforming, loosening, or rebounding due to auxiliary support, thus effectively ensuring the drilling accuracy.

[0092] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0093] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0094] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0095] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0096] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0097] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
