Description

[0002] The function of the heliostat in tower solar thermal power generation is to concentrate sunlight on the heat absorber. A large number of heliostats are required in each mirror field to reflect enough heat to the heat absorber. As the main component of the mechanical structure of the heliostat, the machining accuracy of the holes on the main beam directly affects the accuracy of the assembled heliostat. The existing main beam is equipped with a main beam support and a push rod support, and holes need to be machined on both the main beam support and the push rod support to cooperate with other components to achieve the angular deflection of the heliostat. To improve the assembly efficiency, the main beam support with holes and the push rod support with holes are generally installed on the main beam. Due to assembly errors during the installation process or deformation of the main beam during welding, the axes of the holes on the main beam support and the push rod support are not parallel, which affects the rotation accuracy of the heliostat and may even cause jamming, resulting in the inability of the heliostat to rotate.

[0045] Before explaining any embodiment of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements described in the following description or shown in the above accompanying drawings.

[0046] In this application, the terms "comprise", "include", "have" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0047] In this application, the term "and / or" describes the relationship between associated objects and indicates that three relationships can exist. For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this application, the character " / " generally indicates that the associated objects before and after are in an "and / or" relationship.

[0048] In this application, the terms "connect", "combine", "couple", "mount" can be direct connection, combination, coupling or mounting, or can be indirect connection, combination, coupling or mounting. Among them, by way of example, direct connection means that two parts or components are connected together without the need to provide an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0049] In this application, those of ordinary skill in the art will understand that relative terms used in connection with a quantity or condition (such as "about", "approximately", "substantially", etc.) are intended to include the stated value and have the meaning indicated by the context. For example, such relative terms at least include the degree of error associated with the measurement of a particular value, tolerances caused by manufacturing, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. Relative terms may refer to plus or minus a certain percentage (such as 1%, 5%, 10% or more) of the indicated value. A numerical value without the use of a relative term should also be disclosed as a particular value with a tolerance. In addition, when expressing a relative angular position relationship (such as substantially parallel, substantially perpendicular), "substantially" may refer to plus or minus a certain number of degrees (such as 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0050] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0051] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", and "back" are described based on the orientation and positional relationship shown in the drawings, and should not be construed as limiting the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component. It should also be understood that the orientation terms such as the upper side, the lower side, the left side, the right side, the front side, and the back side not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side can include directly below, lower left, lower right, lower front, and lower back, etc.

[0052] As Figures 1 to 4 shown, this embodiment provides a hole processing device, which is used to process post-processing holes on the mirror mounting structure 1000, and the mirror mounting structure 1000 is configured to mount the heliostat mirror; both the first base 1100 and the second base 1200 are installed on the mirror mounting structure 1000, and a pre-processed hole is provided in the first base 1100. The hole processing device includes a frame 100, a positioning structure 200, a positioning component 300, and a hole processing component 400. Among them, the positioning structure 200 includes a penetrating section and a positioning section. The penetrating section is used to penetrate into the pre-processed hole and is coaxially arranged with the pre-processed hole; the axis of the positioning section and the axis of the penetrating section are on the same straight line, or the axis of the positioning section is parallel to the axis of the penetrating section; the positioning component 300 is used to restrict the positioning structure 200 along the radial direction of the positioning section; the hole processing component 400 includes a hole processing part 410, and the hole processing part 410 can move along the axis direction of the penetrating section and is used to process post-processing holes on the second base 1200. The above settings make the axis of the penetrating section of the positioning structure 200 the same as the center line of the pre-processed hole. At the same time, the hole processing part 410 in the hole processing component 400 moves along the axis direction of the penetrating section of the positioning structure 200 and processes post-processing holes on the second base 1200, so as to ensure that the center line of the pre-processed hole and the center line of the post-processing hole are parallel. After being combined with the driving structure of the heliostat, it is beneficial to ensure the smooth flipping of the heliostat mirror and the flipping accuracy.

[0053] It should be specifically noted that in this solution, the post-machining holes located on the second base 1200 are positioned and machined through the pre-machined holes on the first base 1100, so as to make the center line of the post-machining holes parallel to the center line of the pre-machined holes. Among them, the number of pre-machined holes in the first base 1100 and the number of post-machining holes in the second base 1200 are not specifically limited here and can be specifically designed according to the actual situation. In the embodiments of this solution, generally, there are at least two pre-machined holes in the first base 1100, and there are also at least two post-machining holes in the second base 1200. The number of penetrating segments on the positioning structure 200 should correspond to the number of pre-machined holes. Then, the corresponding penetrating segments of the positioning structure 200 are at least two segments and are coaxially arranged with the pre-machined holes. It should also be noted that usually, the center lines of several pre-machined holes on the first base 1100 are on the same straight line. Furthermore, the axes of several penetrating segments on the positioning structure 200 are also on the same straight line. Of course, in other embodiments of this solution, because the center lines of several pre-machined holes are on the same straight line, there is a situation where one penetrating segment of the positioning structure 200 penetrates several pre-machined holes, such as the positioning structure 200 being a Z-shaped structure. The specific structure of the positioning structure 200 is not limited here and can be designed according to the actual situation.

[0054] Exemplarily, when the positioning segment and the penetrating segment are on the same straight line, the entire positioning structure 200 is in a straight shape; when the positioning segment and the penetrating segment are parallel and not on the same straight line, the entire positioning structure 200 is in a several-shaped structure. The above shapes can effectively limit the position of the second base 1200 after radially limiting the positioning segment, so as to realize the limitation of the position of the post-machining holes by the position of the pre-machined holes and ensure that the center line of the post-machining holes is parallel to the center line of the pre-machined holes.

[0055] In some embodiments, the positioning component 300 includes a first positioning member 310 and a second positioning member 320. The cooperation of the first positioning member 310 and the second positioning member 320 can move closer to each other along the direction perpendicular to the axis of the positioning section to constrain the positioning section in the direction perpendicular to the axis of the positioning section. In the implementation of this solution, generally, when the first positioning member 310 and the second positioning member 320 are separated, there is a gap between them, and the positioning section can be placed in the gap between them. Then, when the first positioning member 310 and the second positioning member 320 move closer to each other, they push against the positioning section and limit its position, so that the position of the positioning section is fixed, which is beneficial to ensuring the center line direction of the post-processed hole by the center line direction of the pre-processed hole. Of course, in other embodiments of this solution, the first positioning member 310 is provided with a groove with an upward opening (hereinafter referred to as the first groove for convenience of description). The first groove can accommodate the positioning section of the positioning structure 200 and limit the movement of the positioning section of the positioning structure 200 in the horizontal direction (such as the first groove is a V-shaped groove with an upward opening), and the second positioning member 320 is arranged to be able to limit the position of the mirror mounting structure 1000 (such as the main beam, see the relationship between the main beam and the first base 1100 in the appendix) in the vertically downward direction. Then, when the first base 1100 moves upward, it is limited downward by the mirror mounting structure 1000. At this time, the position of the second base 1200 is also fixed, and further the position of the post-processed hole is also determined. How to specifically set the first positioning member 310 and the second positioning member 320 can be designed according to the actual situation. Figure 1 The relationship between the main beam and the first base 1100 shown in the appendix), then when the first base 1100 moves upward, it is limited downward by the mirror mounting structure 1000. At this time, the position of the second base 1200 is also fixed, and further the position of the post-processed hole is also determined.

[0056] Specifically, as shown in the appendix Figure 2 and the appendix Figure 3 shown, both the first positioning member 310 and the second positioning member 320 extend along the axis of the positioning section. The first positioning member 310 is penetrated with a positioning groove 311 extending along the axis direction of the positioning section of the positioning structure 200. The second positioning member 320 can approach the first positioning member 310 to form a positioning channel with the positioning groove 311, and the positioning section of the positioning structure 200 can pass through the positioning channel. Among them, the positioning groove 311 is a V-shaped groove, and the second positioning member 320 has an abutting surface. The abutting surface and the V-shaped groove form a positioning channel, and at least three side walls of the positioning channel are in contact with the positioning section of the positioning structure 200. The setting of the above structure enables the positioning section to pass through the positioning channel and be effectively limited in the radial direction, ensuring the reliability of the positioning of the positioning section, which is beneficial to ensuring the stability and machining accuracy of the post-processed hole. In addition, the setting of the V-shaped groove can also adapt to positioning sections with different outer diameters, so as to adapt to the mirror mounting structure 1000 with post-processed holes of different diameters.

[0057] In other embodiments, the positioning groove 311 is an arc-shaped groove, the second positioning member 320 has an arc-shaped groove, the positioning section is a round rod, and the round rod is clamped in the two arc-shaped grooves. The setting of the arc-shaped groove is adapted to the round rod structure of the positioning section, so as to more stably and accurately constrain the positioning section. In this embodiment, the second positioning member 320 may also not be provided with an arc-shaped groove, and only a planar structure is provided to cooperate with the arc-shaped groove to complete the constraint of the positioning section.

[0058] In other embodiments, the positioning groove 311 is a shape adapted to the positioning section of the positioning structure 200. The second positioning member 320 has an abutting surface, and the abutting surface and the positioning groove 311 enclose a positioning channel, and at least three side walls of the positioning channel abut against the positioning section of the positioning structure 200. Exemplarily, if the cross-section of the positioning section of the positioning structure 200 is rectangular, then the cross-section of the positioning groove 311 is a rectangle of the same specification as the cross-section of the positioning section of the positioning structure 200. The second positioning member 320 has an abutting surface, and the second positioning member 320 moves to enclose a positioning channel with the positioning groove 311, so that at least three side walls of the positioning channel abut against the positioning section of the positioning structure 200, thereby completing the constraint of the positioning section.

[0059] To facilitate the placement of the positioning section, in some embodiments, Figure 3 As shown, the top of the first positioning member 310 has a horizontal bearing surface 312. The lower side wall of the positioning groove 311 is flush with the bearing surface 312, and the upper side wall 313 of the positioning groove 311 is an inclined surface, which slopes downward in a direction away from the second positioning member 320. During use, first place the positioning section of the positioning structure 200 passing through the pre-processed hole on the bearing surface 312, and then the second positioning member 320 acts to push the positioning section into the positioning groove 311. Among them, the force exerted by the upper side wall 313 of the positioning groove 311 on the positioning section has a downward component force and a component force towards the second positioning member 320, thereby realizing the radial positioning and constraint of the positioning section.

[0060] To improve the positioning efficiency, in some embodiments, the positioning assembly 300 further includes a positioning driving member 330. The positioning driving member 330 is arranged on the frame 100, and its output end is in transmission connection with the second positioning member 320 to drive the second positioning member 320 to approach or move away from the positioning groove 311. The above setting realizes the automatic operation of the second positioning member 320 and improves the positioning efficiency of the positioning section.

[0061] Specifically, in combination with Figure 2As shown, the positioning structure 200 is a positioning pin. The positioning pin includes a columnar pin body 210 and a limiting end portion 220 provided at one end of the pin body 210. The outer diameter of the limiting end portion 220 is larger than that of the pin body 210 and larger than the diameter of the pre-processed hole. The pin body 210 is passed through the pre-processed hole, and the passing section and the positioning section are coaxially arranged to form the pin body 210. The above setting enables, during installation, the passing section to be passed through the pre-processed hole, and the limiting end portion 220 abuts against the first base 1100. On the one hand, it can provide a guiding indication for the cooperation between the two; on the other hand, it can prevent the positioning pin from detaching from the first base 1100 during the passing process, improving the reliability of their cooperation.

[0062] In some embodiments, the mirror mounting structure 1000 is a main beam and is a cylindrical structure. The first base 1100 includes two main beam supports arranged at intervals along the axis of the main beam. Each main beam support is provided with a pre-processed hole, and the two pre-processed holes are coaxially arranged; there are two passing sections, and the two passing sections are respectively passed through the two pre-processed holes. This setting enables the positioning of the two passing sections while positioning the positioning section, thereby effectively limiting the positions of the two main beam supports and ensuring that the center line of the post-processed hole is parallel to the center lines of the two pre-processed holes on the two main beam supports. Of course, in other embodiments of this solution, the main beam may not be a cylindrical structure, that is, the cross-section of the main beam may be an ellipse, a rectangle, a polygon or an irregular shape, etc. The specific structure of the main beam is not limited and can be specifically designed according to the actual situation.

[0063] It should be particularly noted that the number of supports in the first base 1100 is at least one, and the supports in the first base 1100 can be one or a combination of multiple types of supports such as main beam supports, secondary beam supports or push rod supports, etc. This solution does not limit the number of supports in the first base 1100, and of course, it does not limit the specific type of supports in the first base 1100 either, and can be specifically designed according to the actual situation; preferably, the number of supports in the first base 1100 is two and they are main beam supports.

[0064] The second base 1200 includes two push rod supports arranged at intervals along the axis of the main beam, and the hole processing equipment has two hole processing assemblies 400, each hole processing assembly 400 includes a hole processing part 410, the axes of the two hole processing parts 410 in the two hole processing assemblies 400 are collinear, and the two hole processing parts 410 correspond to the two push rod supports one by one. This arrangement enables the two processing assemblies to process the post-processing holes on the two push rod supports respectively, and the axes of the two hole processing parts 410 are collinear, so that the center lines of the two post-processing holes are on the same straight line and are parallel to the center lines of the pre-processed holes at the same time. Of course, in other embodiments of the present scheme, the hole processing part 410 may not correspond to the push rod support one by one, and one hole processing part 410 may process several push rod supports, and the specific arrangement of the hole processing assembly 400 can be adjusted according to the situation. Preferably, the number of hole processing assemblies 400 is the same as the number of push rod supports, and the axes of the hole processing parts 410 in all hole processing assemblies 400 are collinear, and correspond to the push rod supports one by one in position.

[0065] It should be noted that the number of supports in the second base 1200 is at least one, and the supports in the second base 1200 can be one or more combinations of main beam supports, auxiliary beam supports, or push rod supports. This solution does not limit the number of supports in the second base 1200, and of course does not limit the specific type of supports in the second base 1200, which can be designed according to actual conditions. Preferably, the number of supports in the second base 1200 is two, and they are push rod supports.

[0066] Regarding the structure and movement mode of the hole processing member 410, in some embodiments, the hole processing member 410 is a drill bit, and the hole processing assembly 400 includes a first driving member 421 and a second driving member 422; the first driving member 421 is arranged on the frame 100, and its output end reciprocates in the horizontal direction, the first driving member 421 can drive the second driving member 422 to move, and the output end of the second driving member 422 is connected to the hole processing member 410 in a transmission manner to drive the hole processing member 410 to rotate synchronously. The first driving member 421 drives the second driving member 422 to move in the horizontal direction, so as to drive the drill bit to move in the horizontal direction to approach or move away from the push rod support, and complete the drilling work on the push rod support. Among them, the first driving member 421 drives the second driving member 422 to move in the axial direction of the main beam. In some embodiments, considering that the distance between the two push rod supports is small, the two push rod supports are arranged between the two hole processing assemblies 400, so as to facilitate the reasonable arrangement of the hole processing assembly 400 and reduce the difficulty of assembly.

[0067] In some embodiments, the hole processing equipment further includes a pushing component, which is configured to push the mirror mounting structure 1000 along a radial direction of the mirror mounting structure 1000 , and the pushing component includes a loading pusher 650 and a unloading pusher 660 .

[0068] Specifically, refer to the attached Figure 1 and the attached Figure 4 As shown, the pushing assembly includes a loading pushing member 650 and an unloading pushing member 660 disposed on both sides of the axis of the main beam. The loading pushing member 650 is used to push the main beam towards the hole processing assembly 400, and the unloading pushing member 660 is used to push the main beam away from the hole processing assembly 400. Among them, the loading pushing member 650 includes a loading pushing frame and a loading driving mechanism. The loading pushing frame is installed on the frame 100, and the loading driving mechanism is installed on the upper part of the loading pushing frame and is flush with the main beam. The loading driving mechanism can push the main beam towards the hole processing assembly 400 to assist the positioning assembly 300 to complete positioning.

[0069] The unloading pushing member 660 includes an unloading pushing frame and an unloading driving mechanism. The unloading pushing frame is installed on the frame 100, and the unloading driving mechanism is installed on the upper part of the unloading pushing frame and is flush with the main beam. After the post-processing hole is processed, the main beam needs to be disassembled. The unloading driving mechanism can push the main beam away from the hole processing assembly 400, so as to facilitate taking out the main beam upwards. Among them, it should be noted that after the post-processing hole is processed, the second positioning member 320 is first driven away from the first positioning member 310 so that the positioning pin is no longer restricted.

[0070] To ensure the stability of the movement of the main beam, in some embodiments, the hole processing equipment has at least two pushing assemblies arranged at intervals along the axis direction of the mirror mounting structure 1000. Preferably, the two pushing assemblies are arranged on both sides of the positioning assembly 300.

[0071] Since the mirror mounting structure 1000 is the main beam, when machining the post-machining holes, the axial position of the main beam directly affects the movement range and positioning accuracy of the hole machining part 410. In some embodiments, a third base 1300 is installed on the main beam. The hole machining equipment further includes an axial reference member 510, an axial limiting member 520, and an axial driving member 530. Among them, the axial reference member 510 is arranged on the frame 100, the axial driving member 530 is arranged on the frame 100, and its output end is connected to the axial limiting member 520 and drives the axial limiting member 520 to approach or move away from the axial reference member 510. When the axial limiting member 520 approaches the axial reference member 510, it can clamp one of the third base 1300, the first base 1100, and the second base 1200 to limit the axial movement of the main beam. The above setting enables the position of the main beam in its own axial direction to be determined, so that the hole machining part 410 can abut against the push rod support within a preset range and complete drilling. At the same time, during the drilling process, the main beam is axially constrained through the third base 1300, so that it can overcome the thrust exerted by the hole machining part 410 on the push rod support, avoid the axial movement of the main beam along its own axis, and ensure the drilling accuracy and depth. It should be noted that the number of supports in the third base 1300 is at least one, and the supports in the third base 1300 can be one or more combinations of main beam supports, secondary beam supports, or push rod supports. This solution does not limit the number of supports in the third base 1300, nor does it limit the specific type of supports in the third base 1300, which can be designed according to the actual situation. Preferably, the number of supports in the third base 1300 is two, and they are secondary beam supports.

[0072] Considering that during the process of machining the post-machining holes, the drill bit will exert a rotational force on the push rod support. To avoid the situation that the main beam rotates around the axis of the drill bit during the machining process, in some embodiments, as shown in Figure 4 the hole machining equipment further includes a radial fixing assembly 600. The radial fixing assembly 600 includes a support member 610, a pressing member 620, and a pressing driving member 630. The support member 610 is arranged on the frame 100, the pressing member 620 is movably arranged on the frame 100 and can move between a ballast position and an avoidance position. The pressing member 620 and the support member 610 at the ballast position constrain the main beam at least in the vertical direction. The pressing driving member 630 is arranged on the frame 100, and its output end is in transmission connection with the pressing member 620. Among them, the pressing member 620 and the main beam are in line contact. The above setting presses and connects the main beam at least in the vertical direction, so that the torque exerted by the drill bit on the push rod support can be offset during the process of machining the post-machining holes, ensuring the position stability of the main beam, and thus ensuring the machining accuracy of the post-machining holes. Of course, when the weight of the main beam is large enough, that is, when the weight of the main beam can overcome the torque exerted by the drill bit on the push rod support, the main beam can also remain stationary by relying on its own weight to ensure the accuracy of the post-machining holes.

[0073] To ensure that the position of the main beam remains stationary, in some embodiments, the crimping member 620 has a crimping groove 621, and a friction member is provided in the crimping groove 621. The friction bracket abuts against the main beam. Among them, the friction member is made of a buffer material. Specifically, the friction member is a rubber pad. The above settings constrain the main beam and enable a small range of displacement in the radial direction, so as to facilitate the fixing of the position of the positioning structure 200, thereby ensuring the machining accuracy of the post-machined hole.

[0074] During installation, to ensure the position accuracy of the post-machined hole, it is necessary to first limit the axial position of the main beam, and then limit the circumferential rotation angle of the main beam by limiting the pre-machined hole, so as to ensure that the post-machined hole can be accurately machined on the push rod support. For this purpose, in some embodiments, the radial fixing assembly 600 further includes a support column 640. The support column 640 is provided on the frame 100, and the crimping member 620 is provided on the top of the support column 640.

[0075] In some embodiments, the hole machining device has at least two radial fixing assemblies 600, and the at least two radial fixing assemblies 600 are arranged at intervals along the axis direction of the main beam.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
