One reference plate is arranged in the four detection plates, and the reference plate is detachably connected with the corresponding main beam support 613 or push rod support 614.
This embodiment is rational in infrastructure, has simple structure, and is small, light in weight, low in manufacturing cost, convenient to use detects the precision height, collects a plurality of advantages of detecting an item function in an organic whole etc..
The structure of the present embodiment will now be explained. Meanwhile, for convenience of explanation, the first and second main beam support detection plates 15 and 16 are collectively referred to as a main beam support detection plate, and the first and second push rod support detection plates 17 and 18 are collectively referred to as a push rod support detection plate. In addition, in this embodiment, the first main beam support detection plate 15 is selected as a reference plate, and in the detection process, the reference plate, i.e., the first main beam support detection plate 15, corresponds to the right main beam support detection surface 6131. Of course, in other embodiments, other sensing plates may be selected as the reference plate.
As shown in fig. 2, the heliostat generally includes a power box 2, a column 3, an electric push rod 4, a reflector 5, a mirror holder 6, a connecting base 7, and a rotary speed reducer 8. As shown in fig. 3, the main portion of the frame 6 is a main beam weld 61, which generally includes a main beam tube 611, a support beam 612, a main beam support 613, and a push rod support 614.
The handle 11 is the basis of the present invention, the two ends of the handle 11 are respectively provided with a third through hole, the main beam shaft 13 and the push rod shaft 14 respectively penetrate through the two third through holes at the two ends of the handle 11, so that both the main beam shaft 13 and the push rod shaft 14 can rotate (i.e. rotate along the own axis), and at least one of the main beam shaft 13 and the push rod shaft 14 can move left and right (i.e. move along the own axis within a preset range) relative to the handle 11 within a preset range. As shown in fig. 5, in particular, in the present embodiment, the handle 11 includes two arcuate panels 111, two handle sleeves 112, and at least one reinforcing bar 113. The two ends of the two arc-shaped plates 111 are respectively connected through a handle sleeve 112, the arc-shaped plates 111 are sleeved and connected with the handle sleeve 112, and the handle sleeve 112 is arranged to enhance the rigidity of the handle 11; a reinforcing bar 113 is connected between the two curved plates 111 for reinforcing the strength of the handle 11. The connection between each part of the handle 11 can adopt welded connection. To ensure accuracy, the handle sleeve 112 is reworked after the welding of the arcuate panels 111. The handle sleeve 112 is rotatably connected with the main beam shaft 13 and the push rod shaft 14, and can rotate through clearance fit or through a rotating mechanism such as a bearing. Particularly, the handle 11 is designed by comprehensively considering the requirements of assembly precision, weight, convenience in holding and the like, and the space size is designed reasonably.
The relative positions of the main beam welding piece 61 and the push rod welding piece in the left-right direction also allow certain deviation in the manufacturing process, so that the detection condition can be adapted only by means of the fact that at least one of the main beam shaft 13 and the push rod shaft 14 can move left and right, the situation that the distance between the main beam support 613 and the push rod support 614 is qualified is prevented, and the situation that two main beam support detection plates and/or two push rod support detection plates cannot be smoothly placed or cannot be close to corresponding detection surfaces due to the existence of the deviation. Thus, at least one of the main beam shaft 13 and the pusher shaft 14 is slidable left and right in the corresponding handle sleeve 112. In this embodiment, the main beam shaft 13 can slide left and right in the corresponding handle sleeve 112, while the pusher shaft 14 does not. Of course, in other embodiments, the push rod can slide left and right in the corresponding handle sleeve 112, but the main beam shaft 13 cannot, or both the main beam shaft 13 and the push rod shaft 14 can slide left and right in the corresponding handle sleeve 112.
However, the relative positions of the main beam support 613 and the push rod support 614 in the left-right direction are required, so that the main beam shaft 13 and/or the push rod shaft 14 cannot move left and right without limitation in the detection process, and therefore, a limit is also set on the shaft capable of moving left and right to enable the shaft to move left and right within a preset range. The specific mode can be as follows: two handle limiting holes 133 are formed in the shaft capable of moving left and right, the handle 11 is located between the two handle limiting holes 133 of the same shaft, a handle limiting part penetrates through the handle limiting holes 133, and the handle limiting part extends out of the corresponding handle limiting holes 133, so that the handle sleeve 112 is limited and can only move between the two handle limiting holes 133 on the main beam shaft 13 or the push rod shaft 14. In this embodiment, the main beam shaft 13 can slide left and right in the corresponding handle sleeve 112, and the push rod shaft 14 cannot, so that the handle limiting hole 133 is formed on the main beam shaft 13. More specifically, in the present embodiment, the handle limiting hole 133 may be a threaded hole, and the handle limiting member may be a bolt. In other embodiments, the main beam shaft 13 and/or the putter shaft 14 may be limited to a predetermined range of movement relative to the handle 11 in other ways, which are not limited herein.
The four detection plates are all fixedly connected with detection plate sleeves 12, and in the embodiment, the specific connection mode may be welding, but in other embodiments, other connection modes may also be available. The two ends of the main beam shaft 13 and the two ends of the push rod shaft 14 are respectively inserted into the corresponding detection plate sleeves 12, and the detection plate sleeves 12 are rotatably connected with the main beam shaft 13 and the push rod shaft 14, so that the rotation can be realized through clearance fit, and the rotation can also be realized through rotating mechanisms such as bearings.
In the present invention, the main beam shaft 13 and the push rod shaft 14, and only one end of the detection plate sleeve 12 at both ends of each shaft can slide within a preset range along the axial direction of the shaft. In this embodiment, the detector plate sleeve 12 on the first main beam support detector plate 15 is fixedly connected to the main beam shaft 13, the detector plate sleeve 12 on the second main beam support detector plate 16 is slidably connected to the main beam shaft 13, the detector plate sleeve 12 on the first push rod support detector plate 17 is fixedly connected to the push rod shaft 14, and the detector plate sleeve 12 of the second push rod support detector plate 18 is slidably connected to the push rod shaft 14.
Specifically, detection plate sleeve 12 and girder axle 13 on first girder support detection plate 15, detection plate sleeve 12 and push rod axle 14 on first push rod support detection plate 17 are fixed connection, and fixed connection's mode all can be: the detection plate sleeve 12, the main beam shaft 13 and the push rod shaft 14 are all provided with first through holes, and the connecting piece penetrates through the first through holes in the detection plate sleeve 12 and the first through holes 131 and 141 in the corresponding main beam shaft 13 or push rod shaft 14 so as to fixedly connect the detection plate sleeve 12 with the main beam shaft 13 or push rod shaft 14. More specifically, the connecting member may be a cylindrical pin, the cylindrical pin is in interference fit with the first through hole on the detection plate sleeve 12, and the cylindrical pin is in clearance fit with the first through holes 131 and 141 on the main beam shaft 13 and the push rod shaft 14.
The detector plate sleeve 12 on the second main beam support detector plate 16 is slidably connected with the main beam shaft 13 through a main beam sliding mechanism, and the detector plate sleeve 12 on the second push rod support detector plate 18 is slidably connected with the push rod shaft 14 through a push rod sliding mechanism. The same slide mechanism may be used for the main beam slide mechanism and the push rod slide mechanism, and the slide mechanism includes a detector plate sleeve 12 on the second main beam support detector plate 16 or the second push rod support detector plate 18, detector plate limit holes 132, 142 on the main beam shaft 13 or the push rod shaft 14, and a detector plate limit member. The detection plate sleeve 12 is provided with a second through hole, and the detection plate limiting member penetrates through the second through hole and the detection plate limiting holes 132 and 142, is fixedly connected with the second through hole, and is connected with the detection plate limiting holes 132 and 142 in a sliding manner. More specifically, the detection plate limiting members may be cylindrical pins, and the cylindrical pins are slidably connected with the detection plate limiting holes 132 and 142 and are in interference fit with the second through holes. The detection plate limiting holes 132 and 142 may be rectangular holes, kidney-shaped holes, etc., as long as the corresponding detection plates can slide along the axial direction of the main beam shaft 13 or the push rod shaft 14; the two handle limiting holes 133 on the main beam shaft 13 are located between the first through hole 131 and the detection plate limiting hole 132 on the main beam shaft 13.
Therefore, in the present invention, at least one end of the detection plate sleeves 12 at both ends of the main beam shaft 13 and the push rod shaft 14 can slide in a preset range along the axial direction of the shaft because: the distance between the two main beam support detection plates and the two push rod support detection plates is the distance between the main beam support 613 and the push rod support 614, and the distance allows certain error to exist, and the error is embodied in the distance that the detection plate connecting piece can slide left and right in the detection plate limiting holes 132 and 142. This is also because, in other implementations, the connection between the main beam shaft 13 and the push rod shaft 14 and the detection plate sleeves 12 at the two ends may be all sliding connections achieved through a sliding mechanism, that is, the fixed connection between the detection plate sleeve 12 on the first main beam support detection plate 15 and the main beam shaft 13 in this embodiment is changed to sliding connection achieved through the main beam sliding mechanism, and the fixed connection between the detection plate sleeve 12 on the first push rod support detection plate 17 and the push rod shaft 14 is changed to sliding connection achieved through the push rod sliding mechanism. When the two ends of the main beam shaft 13 and the push rod shaft 14 are in sliding connection, the allowable error is the sum of the distance that the detection plate connecting pieces at the two ends of the shafts can slide left and right in the limit holes of the detection plate.
Further, the first and second main beam support detection plates 15, 16 each have a profile identical to the profile of the upper portion of the main beam support 613, and the first and second push rod support detection plates 17, 18 each have a profile identical to the profile of the upper portion of the push rod support 614.
Further, a locking mechanism may be provided between the detector plate sleeve 12 and the main beam shaft 13 and the push rod shaft 14 for fixedly connecting the detector plate sleeve 12 to the main beam shaft 13 or the push rod shaft 14 in a locked state. Specifically, the locking mechanism comprises a plurality of threaded fasteners and a plurality of threaded holes formed in the detection plate sleeve 12, the threaded fasteners are screwed into the corresponding threaded holes and then screwed into the corresponding threaded holes to abut against the corresponding main beam shaft 13 or push rod shaft 14, and the threaded fasteners are screwed tightly to lock the relative positions of the detection plate sleeve 12 and the main beam shaft 13 or the push rod shaft 14. Generally, the corresponding threaded fastener at the reference plate (in this embodiment, the first main beam support detection plate 15) is normally locked, and the rest is normally unlocked. The corresponding threaded fastener at the first main beam support detection plate 15 is set to be normally locked, so that the positions of the other three detection plates can be adjusted by taking the threaded fastener as a reference, and the other three detection plates can be matched with the corresponding push rod support detection surface and the main beam support detection surface. Therefore, in other embodiments, the threaded fasteners corresponding to the reference plate may be configured to be normally locked, and the threaded fasteners corresponding to the other three detection plates may be configured to be normally unlocked according to the specific reference plate.
The main beam support 613 and the push rod support 614 are bolted when being connected to other structures, and thus bolt mounting holes for bolting are provided on both the main beam support 613 and the push rod support 614.
