[0019] The following further elaborates in detail on a heliostat main beam feeding and pairing device proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description and the claims, the advantages and features of the present invention will become clearer.

[0020] Embodiment 1 Refer to Figures 1 to 7 , this embodiment provides a device for heliostat main beam feeding and pairing, which is used for the feeding and pairing operation of the heliostat main beam 2 and at least one workpiece to be paired 3 (the workpiece to be paired 3 can specifically be a beam piece or other workpieces that need to be welded to the heliostat main beam 2). After the pairing is completed, subsequent welding operations or other processing and installation operations can be carried out. The workpiece to be paired 3 is provided with a mounting through hole, and the workpiece to be paired 3 can be sleeved on the heliostat main beam 2 through the mounting through hole. This heliostat main beam feeding and pairing device includes a base 14 and a positioning part 13; at least one positioning part 13 is arranged at intervals along the preset feeding path on the base 14. The positioning part 13 is configured to be able to fixedly arrange the workpiece to be paired 3 in a preset position (the preset position is the position on the heliostat main beam 2 where the workpiece to be paired 3 is to be installed) along the extending direction of the preset feeding path, so that the heliostat main beam 2 can sequentially pass through all the workpieces to be paired 3; the positioning part 13 includes a first state and a second state. In the first state of the positioning part 13, the workpiece to be paired 3 can be taken out or put into the positioning part 13. In the second state of the positioning part 13, the workpiece to be paired 3 is fixed in the positioning part 13; wherein, the preset feeding path is a preset straight line; in the second state of the positioning part 13, the center line of the mounting through hole of the workpiece to be paired 3 is located on the preset feeding path.

[0021] It should be particularly noted that feeding means pushing the heliostat main beam 2 into the heliostat main beam feeding and pairing device along the preset feeding path, so that the heliostat main beam 2 can sequentially pass through all the workpieces to be paired 3; and in an ideal state, the axis (the axis of the heliostat main beam 2) of the heliostat main beam 2 is a straight line, and the preset feeding path is the straight line where the axis of the heliostat main beam 2 is located after the pairing operation is completed; of course, in many cases, due to processing, transportation and other problems, the axis (the axis of the heliostat main beam 2) of the heliostat main beam 2 is not a straight line, such as a slightly curved arc of the axis of the heliostat main beam 2. How to deal with such situations will be described in detail in subsequent embodiments for the case where the axis of the heliostat main beam 2 is not a straight line.

[0022] Specifically, refer to the attached Figure 1 attachment Figure 2 and attachment Figure 4, generally, the main beam 2 of the heliostat presents a long strip shape as a whole. The component to be paired 3 is provided with a mounting through-hole, and the component to be paired 3 can be sleeved on the main beam 2 of the heliostat through the mounting through-hole; at least one positioning part 13 is arranged at intervals along the preset feeding path on the base 14. Generally, the number of the positioning parts 13 is the same as the number of the components to be paired 3. Such a design can ensure that the main beam 2 of the heliostat can pass through all the components to be paired 3 during the feeding operation, and ensure that all the components to be paired 3 that need to be assembled and installed are installed in place simultaneously (i.e., installed at the preset position); of course, in other embodiments of this technical solution, the number of the positioning parts 13 may be different from the number of the components to be paired 3, or one positioning part 13 may fix multiple components to be paired 3. Here, the specific number of the positioning parts 13 and the number of the components to be paired 3 that each positioning part 13 can fix are not limited, and specific design can be carried out according to the actual situation. The positioning part 13 includes two states, namely the first state and the second state. In the first state, the component to be paired 3 can be taken out or put into the positioning part 13, and when the positioning part 13 is in the second state, the component to be paired 3 is fixed in the positioning part 13, and the center line of the mounting through-hole is located on the preset feeding path, so that the main beam 2 of the heliostat can pass through all the components to be paired 3 during the feeding process, and then welding can be completed uniformly, effectively improving the welding efficiency and solving the problem of low welding processing efficiency of the existing main beam 2 of the heliostat.

[0023] It should be noted that in the embodiment of this technical solution, the main beam 2 of the heliostat presents a long strip circular tube shape as a whole, and its cross-section is circular (that is, generally referring to the outer contour of the cross-section of the main beam 2 of the heliostat). However, in other implementations of this technical solution, the cross-section of the main beam 2 of the heliostat may not be circular, and the cross-section of the main beam 2 of the heliostat may be one of a rectangle, an ellipse, a polygon or an irregular shape. This technical solution does not specifically limit the main beam 2 of the heliostat, and specific design can be carried out according to the actual use situation. It should also be noted that the distance between the positioning parts 13 is not limited, and specific design can be carried out according to the actual situation.

[0024] In the embodiment of this technical solution, the positioning part 13 includes a placement base and a clamping mechanism. A through-hole is provided through the placement base along the extension direction of the preset feeding path, and the placement base is configured to be able to accommodate the component to be paired 3; the clamping mechanism is arranged on the placement base, or the clamping mechanism is arranged on the base 14; the clamping mechanism is configured to be able to press the component to be paired 3 onto the placement base through the action of the clamping mechanism; wherein, when the positioning part 13 is in the second state, there are at least three pressing points between the clamping mechanism and the component to be paired 3.

[0025] Specifically, see the appendix Figure 4As shown, generally, the part to be paired 3 is a beam seat. The positioning part 13 includes a placement base and a clamping mechanism. A through hole (such as the U-shaped through hole shown in the attachment) is provided through the placement base along the extension direction of the preset feeding path. During the feeding operation, the main beam 2 of the heliostat will pass through the placement base from the through hole. Preferably, the through hole is a U-shaped through hole, and such a design facilitates the upward removal of the main beam 2 of the heliostat. Of course, in other embodiments of the present technical solution, the through hole can be designed into through holes of any shape as long as it does not hinder the feeding operation of the main beam 2 of the heliostat. A placement groove with an opening facing the clamping mechanism is also provided on the placement base. The function of the placement groove is to accommodate the beam seat, and then the beam seat is pressed tightly on the placement base by the clamping mechanism to fix the position of the beam seat, facilitating the main beam 2 of the heliostat to pass through all the beam seats in sequence. Preferably, the placement groove has an upward opening and an opening facing the clamping mechanism, and the upward opening facilitates the placement and removal of the beam seat. Figure 4 As shown in, during the feeding operation, the main beam 2 of the heliostat will pass through the placement base from the through hole. Preferably, the through hole is a U-shaped through hole, and such a design facilitates the upward removal of the main beam 2 of the heliostat. Of course, in other embodiments of the present technical solution, the through hole can be designed into through holes of any shape as long as it does not hinder the feeding operation of the main beam 2 of the heliostat. A placement groove with an opening facing the clamping mechanism is also provided on the placement base. The function of the placement groove is to accommodate the beam seat, and then the beam seat is pressed tightly on the placement base by the clamping mechanism to fix the position of the beam seat, facilitating the main beam 2 of the heliostat to pass through all the beam seats in sequence. Preferably, the placement groove has an upward opening and an opening facing the clamping mechanism, and the upward opening facilitates the placement and removal of the beam seat.

[0026] For example, the placement groove can be specifically formed by the cooperation of a base plate provided on the placement base and a fixing plate 132. The base plate is fixed on the placement base, and the fixing plate 132 is vertically or at a certain angle fixed on the base plate. The surface of the fixing plate 132 facing the feeding side is the bearing surface for bearing the part to be paired 3 (beam seat). The precise positioning of the part to be paired 3 can be specifically achieved by providing corresponding alignment blocks or alignment grooves on the bearing surface.

[0027] The clamping mechanism includes a rotating shaft 133, a rotating shaft connecting piece 134, and two clamping components 131. The rotating shaft 133 is rotatably connected to the placement base, and the axis of the rotating shaft 133 is perpendicular to the preset feeding path; the first end of the rotating shaft connecting piece 134 is arranged on the rotating shaft 133; both clamping components 131 are arranged on the rotating shaft 133, and the two clamping components 131 are located on both sides of the preset feeding path. Each clamping component 131 includes at least one contact surface facing the placement base; wherein, when the positioning part 13 is in the second state, the contact surface abuts against the beam piece; each clamping component 131 includes at least one clamping arm 137. Specifically, the rotation of the rotating shaft 133 is driven by the swing of the rotating shaft connecting piece 134, and then the two clamping components 131 located on the rotating shaft 133 swing towards the beam seat, and the pressing operation is performed through the contact surface; the clamping components 131 are arranged on both sides of the preset feeding path so that each clamping component 131 can cooperate to perform multi-point clamping on the beam seat to ensure stable clamping.

[0028] Specifically, refer to Figure 5 and 7, each clamping assembly 131 includes a clamping arm 137, and the first end of the rotating shaft connecting member 134 is disposed between the two clamping arms 137; a connecting member is disposed on at least one clamping arm 137, and the connecting member includes a connecting arm 1311, a pin shaft 1312, and two pressing blocks 1313. A pin hole 1314 is formed through the first clamping arm, and the center line of the pin hole 1314 is parallel to the axis of the rotating shaft 133; the pin shaft 1312 is inserted into the pin hole 1314, and the pin shaft 1312 is configured to dispose the connecting arm 1311 on the first clamping arm; the two pressing blocks 1313 are disposed on both sides of the axis of the pin shaft 1312, and the end surface of the pressing block 1313 facing the placement base is the contact surface; wherein, the first clamping arm is the clamping arm 137 on which the connecting member is disposed. Among them, the connecting arm 1311 can be connected to the swing arm through the pin shaft 1312, the pressing blocks 1313 can be respectively installed on the surface of the connecting arm 1311 facing the fixed structure, and the pressing blocks 1313 are respectively located on both sides of the pin shaft 1312 (if there are two pressing blocks 1313, the pressing blocks 1313 can be respectively arranged at both ends of the connecting arm 1311, and the midpoint position of the connecting arm 1311 is connected to the pin shaft 1312).

[0029] Further, the pressing block 1313 can be specifically designed to be threadedly connected to the connecting arm 1311 through a threaded connecting member, and the position adjustment relative to the connecting arm 1311 can be realized through the threaded connecting member, so as to realize the adjustment of the positional relationship between the contact surface and the clamping arm 137. The pin shaft 1312 can specifically adopt a semi-circular and semi-square structure (the semi-circular and semi-square shape can be understood as cutting a cylindrical shaft body in a manner parallel to the axis, and then obtaining a semi-circular and semi-square shape with an outer contour of an arc and a straight line in the cross section) to cooperate with the corresponding semi-circular and semi-square pin hole 1314 of the connecting arm 1311, ensuring that the connecting arm 1311 can move slightly (i.e., rotate slightly) along the pin shaft 1312.

[0030] It should be particularly noted that the fit between the pin shaft 1312 and the pin shaft hole 1314 is generally an interference fit. However, in other embodiments of this technical solution, the fit between the pin shaft 1312 and the pin shaft hole 1314 may be that there is a threaded member at one end of the pin shaft 1312, and the threaded member extends out of the pin shaft hole 1314 and forms a fit with a nut, so as to fix the connecting arm 1311 to the clamping arm 137; here, the fit between the pin shaft 1312 and the pin shaft hole 1314 is not specifically limited and can be designed according to actual use conditions, as long as it satisfies that the pin shaft 1312 can fix the connecting arm 1311 to the clamping arm 137 and can ensure that the connecting arm 1311 can move slightly along the pin shaft 1312.

[0031] Further, the number of the clamping assemblies 131 may specifically be two. One is a clamping assembly 131 with multi-point pressing, and only one pressing point may be provided on the other clamping assembly 131 (for example, only a combination including a clamping arm 137 fixedly connected to the rotating shaft 133 and a pressing block 1313). Two pressing blocks 1313 are provided on the clamping assembly 131 with multi-point pressing to form two clamping points. The two clamping assemblies 131 are respectively located on both sides of the preset feeding path, and a three-point contact pressing scheme capable of reliably fixing the parts to be paired 3 can be formed. During the clamping process, the pressing blocks 1313 of the clamping assembly 131 with multi-point pressing can be adaptively adjusted according to the flatness of the parts to be paired 3 (beam pieces), and form a reliable three-point contact with the fixing plate 132 to press the parts to be paired 3, so as to fully and reliably fix the parts to be paired 3.

[0032] In the embodiment of the present technical solution, the feeding and pairing device 1 may further include a driving mechanism. The driving mechanism includes a first driving member, a slide rail, and a connecting rod 135. The slide rail is arranged on the base 14, the connecting rod 135 is slidably connected in the slide rail, and the axis of the connecting rod 135 is parallel to the preset feeding path. The first driving member is configured to provide a driving force for the connecting rod 135 so that the connecting rod 135 can move in the slide rail along its own axis direction. Among them, the second ends of all the rotating shaft connectors 134 are respectively connected to the connecting rod 135. Further, the first driving member may specifically be a clamping cylinder 136. The clamping cylinder 136 is arranged on the base 14 and the output end of the clamping cylinder 136 is connected to the connecting rod 135. That is, the driving force is output to the rotating shaft connector 134 by driving the connecting rod 135 to slide on the base 14 through the clamping cylinder 136.

[0033] Embodiment Two See Figure 3 , on the basis of the above Embodiment One, at least one guiding mechanism 12 is further arranged on the feeding and pairing device 1 in this embodiment. All the guiding mechanisms 12 are arranged on the base 14 at intervals along the preset feeding path in sequence. The guiding mechanism 12 includes a first member and a second member. The cooperation of the first member and the second member can approach each other in the direction perpendicular to the preset feeding path to restrict the heliostat main beam 2 in the direction perpendicular to the preset feeding path, so as to control the geometric center of the corresponding section of the heliostat main beam 2 to be located on the preset feeding path.

[0034] Further, at least one guiding mechanism 12 is arranged on one side of each positioning portion 13 along the extending direction of the preset feeding path. That is, during the feeding process of the heliostat main beam 2 entering the positioning portion 13, it first passes through the guiding mechanism 12 and then penetrates into the corresponding positioning portion 13.

[0035] By setting up the guiding mechanism 12, the guiding mechanism 12 clamps the heliostat main beam 2 in the corresponding section and applies a clamping force, so that the heliostat main beam 2 in the corresponding section always remains on the axis matching the preset feeding path, to overcome the situation that the heliostat main beam 2 deviates from the preset feeding path due to the straightness and ovality deviations, and further ensure that the heliostat main beam 2 can smoothly penetrate into the next mating part 3 (beam seat). The setting of the guiding mechanism 12 enables the feeding and pairing device 1 to have the advantages of high tolerance rates for the straightness and roundness of the circular tube of the heliostat main beam 2, and can efficiently and high-quality complete the pairing before the welding of the heliostat main beam 2.

[0036] In the embodiment of this technical solution, in order to ensure the stability and accuracy of clamping, the guiding mechanism 12 includes at least three pressing points arranged around the heliostat main beam 2. The number of pressing points is specifically determined according to the cross-sectional shape of the heliostat main beam 2, and no specific limitation is made here. In the clamping configuration, each pressing point presses and is in sliding contact or rolling contact with the heliostat main beam 2 (for example, if the cross-section of the heliostat main beam 2 is circular, based on the fact that three points can determine a circle, the number of pressing points can be three or more; if the cross-section of the heliostat main beam 2 is rectangular, based on the number of side lines, the number of pressing points can be four or more). And each pressing point is set so that the connection lines between adjacent pressing points enclose a closed figure (that is, each pressing point is not on the same straight line).

[0037] In the embodiment of this technical solution, the second component includes at least one limiting arm 121; the first component is the second driving member 122. The second driving member 122 is provided with at least one driving end, and the driving end is connected to the limiting arm 121. The second driving member 122 drives the limiting arm 121 to move through the driving end; wherein, the number of driving ends is the same as the number of limiting arms 121, and the driving ends and the limiting arms 121 are arranged in one-to-one correspondence. Specifically, there are two limiting arms 121, and the two limiting arms 121 are arranged on both sides of the preset feeding path and are symmetrically arranged.

[0038] The second driving member 122 drives the limiting arm 121 to move towards or away from the heliostat main beam 2 through the movement of the driving end. By controlling the stroke of the second driving member 122 driving the limiting arm 121 to move, the deviation correction of the heliostat main beam 2 relative to the preset feeding path can be controlled. For example, when the cross-section of the heliostat main beam 2 is circular, two limiting arms 121 can be set, which are respectively arranged on both sides in the radial direction of the heliostat main beam 2. Two pressing points are set on one limiting arm 121, and one or two pressing points are set on the other limiting arm 121. The second driving member 122 drives the two limiting arms 121 to move towards the heliostat respectively, and the clamping of the heliostat main beam 2 and the application of the clamping force can be realized.

[0039] Specifically, the two limit arms 121 are respectively provided with a V-shaped groove with an opening facing the preset feeding path, and at least one universal ball is respectively provided on each groove wall of the V-shaped groove, thereby avoiding the situation where one of the two clamping surfaces cannot contact the heliostat main beam 2, and the provision of the universal ball can ensure that the end of the heliostat main beam 2 can pass through by applying a small pressure. The second driving member 122 can be set as a clamping cylinder with two output rods (the two output rods are the above-mentioned driving ends), or two clamping cylinders are respectively provided. Of course, in other embodiments of the present technical solution, the second driving member 122 can also be a linear driving component such as an electric push rod and a hydraulic cylinder, which can be specifically designed according to actual conditions.

[0040] After the heliostat main beam 2 is inserted between the parts to be matched 3 (support beam seats) and the matching is completed, the clamping cylinder can be controlled to apply a higher cylinder pressure, thereby ensuring that the various sections of the heliostat main beam 2 are distributed on the preset feeding path, so that the gap between the heliostat main beam 2 and the parts to be matched 3 is uniform, thereby ensuring the welding quality of the weld.

[0041] In other embodiments, the guide mechanism 12 may also be configured in a form similar to a three-jaw chuck on a machine tool, that is, a through hole for the heliostat main beam 2 to pass through is disposed at the center of the three-jaw chuck, and the three jaws can achieve clamping by retracting toward the center.

[0042] The setting of the guide mechanism 12 of this embodiment has a high tolerance rate for the straightness and ovality of the round tube of the heliostat main beam 2, which can ensure that the clamping straightness meets the national standard requirements and the round tube of the heliostat main beam 2 that exceeds the tolerance within a certain range. When loading, no matter in which direction the round tube is bent, the guide mechanism 12 can correct and adjust the straightness of the heliostat main beam 2 to ensure that the round tube easily penetrates the support beam piece, increase the clamping force before welding, further fix the heliostat main beam 2 at the theoretical center position, ensure that the hole gap between the heliostat main beam 2 and the part to be matched 3 (support beam piece) is uniform, thereby ensuring the welding quality.

[0043] In an embodiment of the present technical solution, the loading assembly device 1 may further include a loading preparation frame 11, on which rollers are arranged, so that the heliostat main beam 2 can slide axially on the loading preparation frame 11, thereby facilitating the loading operation.

[0044] Furthermore, due to the long length of the heliostat main beam 2, the loading preparation frame 11 can be split into two or more sub-preparation frames arranged along the axial direction, thereby saving materials. The above-mentioned base 14 and the loading preparation frame 11 can both adopt a square tube welding structure, and the base 14 adopts an integrated welding structure to ensure stable positioning accuracy.

[0045] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, provided that these changes fall within the scope of the claims of the present invention and equivalent technologies, they still fall within the protection scope of the present invention.
