Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to a photoelectric turntable. Background Art

[0002] The photoelectric turntable integrates the functions of short cruise cycle, all-weather monitoring, high image recognition, accurate positioning, and real-time data transmission, effectively improving the outdoor monitoring capability. The photoelectric turntable can rotate horizontally and pitch, and it mostly swings back and forth within a fixed angle range when pitching. The larger the pitch swing angle, the greater the impact on the height and weight of the whole machine. However, in actual use, a larger monitoring range is often required.

[0003] In the related art, a lead screw is used to drive the entire photoelectric turntable to rise and fall in the vertical direction, and the corresponding monitoring range is changed by adjusting the position of the entire photoelectric turntable in the height direction. Such a setting does not need to affect the structure of the photoelectric turntable itself, and only needs to install the entire machine on a lifting platform with a lead screw drive. However, such a setting not only requires the addition of an external drive structure at the location where the photoelectric turntable is installed, which increases the installation process, but is also still not conducive to adjusting the pitch swing range of the ball chamber. Summary of the invention

[0004] Based on this, it is necessary to provide a photoelectric turntable that can adjust the pitch angle of the ball warehouse and improve the monitoring range by adjusting the height of the rotation center of the ball warehouse; moreover, the photoelectric turntable does not rely on external lifting drive, reduces the installation process relative to the target position, and does not need to significantly increase the height of the whole machine, which is convenient for transportation and assembly.

In the following description, many specific details are set forth to facilitate a full understanding of the present application.

[0032] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0033] In the related art, in order to adjust the monitoring range of the photoelectric turntable, the photoelectric turntable is usually installed on a lifting platform. Specifically, the lifting platform includes a support table and a screw transmission mechanism for driving the support table to rise and fall in the vertical direction. The photoelectric turntable is installed on the support table, and the photoelectric turntable is driven to rise and fall synchronously through the support table under the action of the screw transmission mechanism. Such a setting is equivalent to adjusting the height of the photoelectric turntable along the vertical direction, thereby adjusting the monitoring field of view of the photoelectric turntable. When the overall height of the photoelectric turntable is increased, the corresponding monitoring range is larger under the same pitch range.

[0034] That is to say, in the related art, the photoelectric turntable is driven from the outside to adjust the monitoring range by changing the height of the whole machine. This leads to the need to add an external drive structure at the location where the photoelectric turntable is installed, and the assembly of the external drive structure also requires a certain amount of space. If the photoelectric turntable needs to be installed at a higher position, the installation process will be increased. Moreover, although such a setting can meet the changes in the pitch range, for the photoelectric turntable itself, the achievable pitch range still cannot be adjusted. If a situation is not conducive to the installation of an external drive, the range adjustment will inevitably not be met.

[0035] In addition, if the ball bin of the photoelectric turntable can be swung in the pitch range of -90° to +90° during the pitch rotation, the corresponding detection blind spot will be smaller. However, due to the shape of the ball bin, there is a risk of interference between the rotation radius of the ball bin and the support base, which prevents it from rotating to -90° when it rotates downward. If such a pitch rotation range is required, the rotation space for the ball bin needs to be increased, that is, the height of the support base used to support the swing of the ball bin needs to be extended, which increases the height and weight of the entire photoelectric turntable, which is not conducive to transportation and assembly.

[0036] In this regard, Figure 1 As shown, the photoelectric turntable provided in one embodiment of the present application can adjust the pitch angle of the detection chamber by adjusting the rotation center height of the ball chamber 21, thereby adjusting the monitoring range; and the photoelectric turntable does not rely on an external lifting drive, reduces the installation process relative to the target position, and does not need to significantly increase the height of the whole machine, which is convenient for transportation and assembly. The specific structure of the photoelectric turntable is described in detail below.

[0037] See also Figure 1 and Figure 3 , exemplarily, the photoelectric turntable includes a support assembly 10, a detection chamber assembly 20 and a lifting assembly 30. The detection chamber assembly 20 includes a ball chamber 21, a support arm 23 and a connecting plate 22. The support arm 23 is movably connected to the connecting plate 22, and is enclosed together with the connecting plate 22 to form an assembly space 201 for assembling the ball chamber 21. The ball chamber 21 is rotatably connected to the support arm 23 and can pitch and swing in the assembly space 201. The connecting plate 22 is rotatably connected to the support assembly 10, and then drives the ball chamber 21 to rotate horizontally through the support arm 23. The support assembly 10 has a rotation axis along the vertical direction (for example, the Z axis), and the ball chamber 21 has a pitch and swing axis along the horizontal direction (for example, the X axis). Then, the support assembly 10 drives the connecting plate 22 to rotate around the rotation axis to realize the rotation of the ball chamber 21 around the rotation axis, so as to realize the adjustment of the horizontal monitoring range; and the ball chamber 21 can pitch and swing relative to the support arm 23 around the pitch and swing axis to realize the adjustment of the vertical monitoring range.

[0038] The lifting assembly 30 is disposed on the connecting disk 22 and connected to the support arm 23. The lifting assembly 30 is used to drive the support arm 23 to lift and lower relative to the connecting disk 22 in the vertical direction, thereby driving the ball bin 21 to lift and lower synchronously to change the distance a between the ball bin 21 and the connecting disk 22 in the vertical direction.

[0039] Among them, a horizontal rotation axis is provided between the support arm 23 and the ball bin 21, and the axis of the horizontal rotation axis is the aforementioned pitch swing axis. The ball bin 21 is provided with support arms 23 on both sides of the horizontal rotation axis to ensure support stability. The two support arms 23 are movably connected relative to the connecting plate 22, and together form a U-shaped assembly space 201, the two support arms 23 are equivalent to the two vertical sides of the U-shape, and the connecting plate 22 is equivalent to the horizontal side of the U-shape.

[0040] That is to say, the support arm 23 and the connecting plate 22 together constitute the aforementioned support base for rotating and supporting the ball warehouse 21. Due to the separate arrangement of the support arm 23 and the connecting plate 22, it is convenient for the support arm 23 to move relative to the connecting plate 22 in the vertical direction, thereby driving the horizontal rotation axis to move in the vertical direction to change the distance between the pitch swing axis of the ball warehouse 21 and the bottom of the assembly space 201. Among them, the pitch swing axis serves as the rotation center of the pitch rotation of the ball warehouse 21. Therefore, when the support arm 23 moves upward in the vertical direction (i.e., the Z-axis direction) under the action of the lifting assembly 30, the distance between the pitch swing axis and the bottom of the assembly space 201 can be increased; conversely, when the support arm 23 moves downward in the Z-axis direction under the action of the lifting assembly 30, the distance between the above two is reduced. When the distance between the above two increases, for example, the ball warehouse 21 rotates downward, especially rotates downward to -90°, the risk of interference between the ball warehouse 21 and the connecting plate 22 is reduced. In this way, the ball chamber 21 can be required to pitch and swing between -90° and +90°, which greatly ensures the monitoring range in the vertical direction.

[0041] Moreover, such a setting in the present embodiment is equivalent to integrating the lifting assembly 30 into the photoelectric turntable body, specifically integrated into the connection plate 22 of the detection chamber assembly 20, so when manufacturing the photoelectric turntable body, the assembly of the lifting assembly 30 and the photoelectric turntable body can be satisfied. Therefore, when the photoelectric turntable is installed to the target position, there is no need to add an external drive structure independent of the photoelectric turntable, simplifying the installation process; and the photoelectric turntable does not rely on the external drive structure, and only relies on the height adjustment of the rotation center of its own ball chamber 21 (specifically the rotation center of the pitch rotation) to increase the pitch swing range, thereby increasing the detection range. In addition, such a setting can use the lifting assembly 30 to drive the support arm 23 to move downward in the vertical direction when the photoelectric turntable needs to be transported, so as to reduce the height of the rotation center of the ball chamber 21, thereby reducing the angle of the ball chamber 21 swinging arbitrarily during transportation, improving transportation stability, reducing interference and collision risks, and being more conducive to the transportation and assembly of the entire photoelectric turntable.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 Optionally, the support arm 23 includes a support portion 231 and a sliding portion 232 connected to the support portion 231, and the support portion 231 is rotatably connected to the ball bin 21. The connecting plate 22 is provided with an assembly cavity 2201 and an assembly hole 2202 communicating with the assembly cavity 2201. The lifting assembly 30 is provided in the assembly cavity 2201 and connected to the connecting plate 22, and the sliding portion 232 of the support arm 23 passes through the assembly hole 2202 and extends into the assembly cavity 2201 to be connected to the lifting assembly 30, and then the support portion 231 and the ball bin 21 are driven to rise and fall in the vertical direction under the action of the lifting assembly 30.

[0043] Since the lifting assembly 30 is arranged in the assembly cavity 2201 of the connection plate 22, it protects the lifting assembly 30 itself and the connection between the lifting assembly 30 and the support arm 23, reducing the risk of damage to the photoelectric turntable when used in an external environment, and ensuring the sustainability of its rotation center lifting. At the same time, it is precisely because of the accommodation of the assembly cavity 2201 for the lifting assembly 30 that the lifting assembly 30 can be prevented from occupying the assembly space 201 of the ball warehouse 21, greatly ensuring the pitch range and rotation center height of the ball warehouse 21.

[0044] The setting of the assembly hole 2202 is not only conducive to the sliding part 232 extending into the assembly cavity 2201 and cooperating with the lifting assembly 30, but also conducive to the sliding part 232 cooperating with the hole wall of the assembly hole 2202 to realize the movement and guidance relative to the connecting plate 22. The axial direction of the assembly hole 2202 is along the vertical direction. When the sliding part 232 is lifted and lowered under the action of the lifting assembly 30, the sliding part 232 is lifted and lowered in the vertical direction relative to the assembly hole 2202 to reduce the offset of the sliding part 232, thereby ensuring the stability of the ball warehouse 21. Among them, the cross-sectional shape of the sliding part 232 is adapted to the cross-sectional shape of the assembly hole 2202, and the sliding part 232 is slidably matched with the hole wall of the assembly hole 2202. In actual use, an anti-wear pad can be added to the hole wall of the assembly hole 2202 to reduce the wear between the hole wall and the sliding part 232.

[0045] See also Figures 1 to 3Furthermore, the photoelectric turntable also includes a locking assembly 50, which is used to lock the support arm 23 to the connecting disk 22. Specifically, the connecting disk 22 is provided with extensions 221 on both sides of the axial direction of the horizontal axis of the ball bin 21, so that the connecting disk 22 itself is arranged in a U shape. Each extension 221 extends upward in the vertical direction, and each extension 221 is correspondingly provided with an assembly hole 2202 connected to the assembly cavity 2201, and each assembly hole 2202 is correspondingly provided with a support arm 23. The provision of the extension 221 is equivalent to lifting the assembly of the support arm 23 and the connecting disk 22 to ensure that there is sufficient spacing between the rotation center of the ball bin 21 and the horizontal side of the connecting disk 22 to meet the minimum pitch angle adjustment of the ball bin 21. Each extension 221 is provided with a mounting hole on the side of the horizontal axis away from the sliding portion 232, and the sliding portion 232 corresponding to each extension 221 is provided with a locking hole. The locking assembly 50 includes at least two locking pieces, each of which passes through a corresponding mounting hole to be threadedly connected to the hole wall of the corresponding locking hole to achieve locking of the support arm 23 and the connecting plate 22 .

[0046] That is to say, after the support arm 23 is moved into position, the locking assembly 50 can be used to connect the support arm 23 relative to the connecting disk 22, so that the support arm 23 is simultaneously supported by the connecting disk 22 and the lifting assembly 30, which not only improves the connection reliability between the support arm 23 and the connecting disk 22, but also relieves the load of the lifting assembly 30.

[0047] Alternatively, the locking assembly 50 may also include a cam and a slot, one of which is provided on the hole wall of the assembly hole 2202, and the other is provided on the sliding portion 232. The cam and the slot are engaged to realize the locking and positioning of the support arm 23 and the connecting plate 22, thereby improving the connection reliability. Among them, the slots may be provided in multiple numbers along the vertical direction and arranged at intervals, and the multiple slots may be engaged with the cam. The cam and the slot may be spherically engaged, which is conducive to the cam being moved out of or into the slot and reduces wear.

[0048] like Figure 2 As shown, in some embodiments, the end surface of the extension end of the extension portion 221 located at the edge of the assembly hole 2202 serves as the bearing surface 2211. The sliding portion 232 is provided with a limiting step 233, including a limiting end surface in the horizontal direction. The limiting end surface can overlap the bearing surface 2211 after the sliding portion 232 drops to a certain height, serving as a descending limit of the support arm 23, and preventing the support arm 23 from moving too much downward to cause the ball bin 21 and the connecting plate 22 to get stuck. Among them, the bearing surface 2211 and the limiting step 233 can be plane matching, of course, can also be curved matching, or even line contact, as long as they can meet the movement limit.

[0049] Before the photoelectric turntable leaves the factory, the limit end surface on the support arm 23 fits with the bearing surface 2211 on the connecting plate 22, so that the rotation center of the ball bin 21 is at the lowest position. In the subsequent use, the lifting assembly 30 can be activated according to actual needs to adjust the support arm 23 to move up in the vertical direction to increase the pitch range of the ball bin 21.

[0050] In some specific embodiments, the support portion 231 is provided with a limiting step 233 at the sliding portion 232 to form an inverted L-shaped groove, and the corresponding horizontal side serves as the limiting end face of the sliding portion 232, which is used to abut against the bearing surface 2211 for limiting. The limiting step 233 can be provided on the side of the support portion 231 facing the ball bin 21 along the axial direction of the horizontal rotation axis, or on the side away from the ball bin 21, or both sides are provided with the limiting step 233.

[0051] See also Figure 1 , Figures 3 to 7 In some of the embodiments, the bracket assembly 10 includes a rotating disk 11 and a support seat 12, and the rotating disk 11 is rotatably connected to the support seat 12. The aforementioned connecting disk 22 is connected to the rotating disk 11. Specifically, the rotating disk 11 is connected to the support seat 12 through a rotating shaft, and the axial direction of the rotating shaft is arranged along the vertical direction, and the axis of the rotating shaft serves as the rotating axis of the bracket assembly 10. The rotating disk 11 rotates around the axis of the rotating shaft relative to the support seat 12, thereby driving the connecting disk 22 to rotate synchronously, and the connecting disk 22 drives the ball bin 21 to rotate synchronously through the support arm 23, thereby adjusting the horizontal angle of the ball bin 21.

[0052] Among them, the connecting disk 22 can be locked with the rotating disk 11 by screws, etc. In some specific embodiments, the connecting disk 22 is provided with a connecting platform 222 radially protruding inwardly on one side of the rotating disk 11, and the connecting platform 222 is provided with a positioning column 2221 protruding downwardly on one side of the rotating disk 11 in the vertical direction, and the rotating disk 11 is correspondingly provided with a positioning hole 1101 for the positioning column 2221 to penetrate, and the positioning column 2221 is penetrated in the positioning hole 1101 to connect the connecting disk 22 to the rotating disk 11 into an integral structure, which is conducive to synchronous rotation. Corresponding connecting platforms 222 can be provided on both sides of the connecting disk 22 along the axial direction of the horizontal rotating shaft. At the same time, the connecting platform 222 can also be fixed to the rotating disk 11 by screws to improve the connection reliability.

[0053] Furthermore, the side of the connecting disk 22 facing the rotating disk 11 is open, and the connecting disk 22 and the rotating disk 11 together enclose the aforementioned assembly cavity 2201. The lifting component 30 can be installed on the connecting disk 22, or on the rotating disk 11, or the lifting component 30 is connected to both the connecting disk 22 and the rotating disk 11 to improve the support reliability.

[0054] See also Figures 1 to 3 , Figures 5 to 7Exemplarily, the lifting assembly 30 includes a lifting arm 31 and a driving structure 32 connected to the lifting arm 31, and the lifting arm 31 can be lifted and lowered in the vertical direction under the action of the driving structure 32. The lifting arm 31 is detachably connected to the sliding portion 232 of the corresponding support arm 23 along both sides of the horizontal rotation axis, thereby realizing the lifting and lowering drive of the support arm 23. The lifting arm 31 and the driving structure 32 are both arranged in the assembly cavity 2201. The driving structure 32 can be installed on the rotating disk 11, can also be installed on the connecting disk 22, or can be connected to both the rotating disk 11 and the connecting disk 22.

[0055] The lifting arm 31 is fixed to the sliding portion 232 of the support arm 23 by screws, or can be snap-fitted. The detachable connection between the lifting arm 31 and the support arm 23 is convenient for assembly and disassembly.

[0056] like Figure 2 and Figure 7 As shown, further, both sides of the lifting arm 31 along the horizontal rotation axis are provided with a warp portion 311 extending upward in the vertical direction, and the warp portion 311 is fixed to the sliding portion 232 of the support arm 23. Such a setting moves the connection between the lifting arm 31 and the support arm 23 upward in the vertical direction, ensuring that there is enough descending space below the support arm 23 relative to the rotating disk 11, so as to further maintain the minimum pitch angle of the ball chamber 21. In addition, it is precisely because of the setting of the warp portion 311 that a recessed area can be formed on the side of the lifting arm 31 away from the support arm 23, which is conducive to accommodating the screws connecting the lifting arm 31 and the support arm 23 and reducing interference.

[0057] Specifically, the lifting arm 31 includes a connection portion connected to the driving structure 32 and the aforementioned warping portion 311, and the connection portion is connected to the warping portion 311 on both sides of the axial direction of the horizontal rotation axis. The warping portion 311 includes an inclined section 3111 and a straight section 3112, one side of the inclined section 3111 is connected to the straight section 3112, and the other side is connected to the connection portion, and the straight section 3112 is pressed on the end of the sliding portion 232 and fastened by screws. The spacing between the inclined sections 3111 corresponding to the two warping portions 311 gradually decreases from top to bottom along the vertical direction, so that the straight section 3112 and the outer side of the inclined section 3111 form the aforementioned concave area, which is not only conducive to the connection of the lifting arm 31 with the sliding portion 232 of the support arm 23 through the warping portion 311, but also can accommodate screws for fixing.

[0058] The connection platform 222 on the connection plate 22 can limit the downward displacement of the lifting arm 31. When the lifting arm 31 moves downward under the action of the driving structure 32, it can contact the connection platform 222 to limit the downward position of the support arm 23. A buffer pad can be provided on the side of the connection platform 222 facing the lifting arm 31, and the buffer pad is made of rubber, silicone and other materials to achieve a buffering effect.

[0059] See also Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As another example, the lifting assembly 30 further includes an assembly seat 33, which is disposed on the rotating disk 11 and is used to support the aforementioned driving structure 32. The rotating disk 11 is provided with a rotating hole 1103 for connecting the rotating shaft, and a sealing ring 40 is pressed between the assembly seat 33 and the rotating disk 11, and the sealing ring 40 is arranged around the outer circumference of the rotating hole 1103 to ensure the sealing of the rotating disk 11 at the rotating hole 1103. For example, the rotating disk 11 may be provided with an annular groove on the outer circumference of the rotating hole 1103, and the sealing ring 40 is arranged in the annular groove and pressed between the assembly seat 33 and the rotating disk 11.

[0060] In actual use, the driving structure 32 of the lifting assembly 30 includes a rotating shaft 321, and the two ends of the rotating shaft 321 along its own axial direction are respectively rotatably connected to the rotating disk 11 and the connecting disk 22, and the lifting arm 31 is connected to the rotating shaft 321. The rotating shaft 321 can rotate around its own axis to drive the lifting arm 31 to move along the axial direction of the rotating shaft 321. Among them, the driving structure 32 also includes a power source 324, and the power source 324 is in transmission connection with the rotating shaft 321 to realize the rotation of the rotating shaft 321.

[0061] The lifting arm 31 is threadedly connected to the rotating shaft 321, and since the lifting arm 31 is connected to the aforementioned support arm 23, the support arm 23 is inserted into the assembly hole 2202. Therefore, when the rotating shaft 321 rotates around its own axis, the lifting arm 31 is limited to rotate in the circumferential direction by the support arm 23 and the hole wall of the assembly hole 2202, and can only reciprocate along the axial direction of the rotating shaft 321, thereby realizing the lifting and lowering of the lifting arm 31, thereby driving the support arm 23 and the ball bin 21 thereon to rise and fall synchronously, which is conducive to changing the pitch swing range of the ball bin 21.

[0062] Alternatively, the driving structure 32 further includes an adapter seat 322, which is threadedly connected to the rotating shaft 321. The lifting arm 31 is provided with a through hole, so that the lifting arm 31 is sleeved on the outer side of the adapter seat 322 by using the through hole and connected to the adapter seat 322. At this time, the support arm 23 cooperates with the hole wall of the assembly hole 2202 to limit the circumferential rotation of the lifting arm 31 and the adapter seat 322, thereby ensuring the reciprocating movement of the lifting arm 31 along the axial direction of the rotating shaft 321.

[0063] The assembly seat 33 is provided with an assembly boss protruding outwardly along the radial direction of the rotating shaft 321, and the through hole of the lifting arm 31 is arranged in a stepped hole to match the assembly seat 33. Then, screws are used to pass through the assembly boss and connect with the lifting arm 31 to achieve the fastening of the lifting arm 31 and the assembly seat 33.

[0064] In actual assembly, a first bearing 34 is provided between the rotating shaft 321 and the connecting plate 22, and a second bearing 35 is provided between the rotating shaft 321 and the assembly seat 33. For example, the first bearing 34 is a ball bearing, and the second bearing 35 is a cylindrical roller bearing. This is only an example.

[0065] like Figure 5 and Figure 6 As shown, further, the driving structure 32 also includes a transmission unit 323, and the transmission unit 323 is connected between the rotating shaft 321 and the power source 324. The rotating shaft 321 is arranged as a stepped shaft, including a large diameter section and a small diameter section connected to the large diameter section, the small diameter section is connected to the lifting arm 31 by transmission, and the large diameter section is connected to the transmission unit 323 by transmission. The transmission unit 323 can be a belt drive or a chain drive, and the driving source can be a motor. The motor drives the rotating shaft 321 to rotate through the belt drive or the chain drive, thereby realizing the lifting and lowering of the lifting arm 31.

[0066] In some specific embodiments, the transmission unit 323 may include a driving wheel 3231, a driven wheel 3232 and a transmission belt 3233, wherein the transmission belt 3233 is stretched between the driving wheel 3231 and the driven wheel 3232. The driving wheel 3231 is connected to the power source 324, for example, connected to the motor shaft of the motor by a key; and the driven wheel 3232 is sleeved on the outer side of the rotating shaft 321 and connected to the rotating shaft 321 by a key. In this way, when the motor drives the driving wheel 3231 to rotate, the driven wheel 3232 can be driven to rotate through the transmission belt 3233, thereby realizing the rotation drive of the rotating shaft 321, and meeting the lifting demand of the lifting arm 31.

[0067] Alternatively, the transmission unit 323 includes a driving sprocket, a driven sprocket and a chain, and the three cooperate to realize the rotation of the rotating shaft 321.

[0068] It should be added that when the rotating shaft 321 is driven to rotate by the transmission unit 323, a gear reduction unit can be provided between the transmission unit 323 and the power source 324 to ensure that the rotation speed transmitted to the rotating shaft 321 is relatively low, thereby improving the movement stability of the lifting arm 31. When the power source 324 is used to directly drive the rotating shaft 321 to rotate, a gear reduction unit can also be provided between the power source 324 and the rotating shaft 321.

[0069] Furthermore, the rotating disk 11 is provided with a receiving hole 1102 penetrating in the vertical direction, and the assembly seat 33 is provided with an assembly platform 331 protruding from the receiving hole 1102, and the power source 324 is accommodated in the receiving hole 1102 and screwed to the assembly platform 331. The assembly platform 331 is provided with a penetrating avoidance hole 3311, which is conducive to the drive shaft of the power source 324 extending out to connect with the driving wheel 3231.

[0070] Among them, the support seat 12 of the aforementioned bracket assembly 10 is provided with a support platform 121 on one side facing the rotating disk 11 in the vertical direction, and the support platform 121 is provided with a ring-shaped avoidance groove 1211 corresponding to the power source 324. The lower part of the power source 324 can be accommodated in the avoidance groove 1211 and does not contact the groove wall of the avoidance groove 1211 to reduce interference.

[0071] In other embodiments, the sliding portion 232 is provided with a limiting step 233, and the limiting step 233 is at least located on the side of the sliding portion 232 away from the ball bin 21, and overlaps the side of the connecting disk 22 that is upward in the vertical direction. Specifically, the limiting step 233 cooperates with the bearing surface 2211 of the extension portion 221 on the connecting disk 22. The lifting assembly 30 includes a plurality of pads, and the plurality of pads can be stacked between the limiting step 233 and the bearing surface 2211 of the extension portion 221; and the photoelectric turntable also includes a locking assembly 50 for locking the support arm 23 and the connecting disk 22. In other words, the stacking arrangement of the pads is used to enable the support arm 23 to move relative to the connecting disk 22 in the vertical direction, so as to adjust the rotation center height of the ball bin 21.

[0072] Each support arm 23 corresponds to at least one cushion block. For example, it may correspond to one cushion block, or two, three, or even more cushion blocks. The thickness of each cushion block may be thinner, which is more conducive to adjusting different heights.

[0073] In this embodiment, the connection disk 22 may only be provided with an assembly hole 2202 for the sliding portion 232 of the support arm 23 to penetrate or insert, so as to slide with the support arm 23. Of course, the connection disk 22 may also be provided with an assembly cavity 2201 for accommodating other structures, and the assembly hole 2202 may be connected to the assembly cavity 2201 or may not be connected.

[0074] like Figure 1 and Figure 3 As shown, in some embodiments, a rotation limiter can be provided between the ball bin 21 and the support arm 23 to limit the pitch swing angle of the ball bin 21, so as to prevent the corresponding pitch swing angle from being oriented to 90° when the rotation center of the ball bin 21 is at the highest point. The rotation limiter can be a sensor, for example, the sensor is provided on the support arm 23, and the trigger sheet is provided on the ball bin 21. When the trigger sheet triggers the sensor, a rotation alarm can be generated to maintain the power mechanism driving the horizontal shaft to stop rotating or reversely rotate. Of course, the rotation limiter can also be a limit block. The limit block can be movably connected to the support arm 23. When the rotation center of the ball bin 21 is at the highest point, the limit block extends to limit the pitch swing angle of the ball bin 21. The limit block can be movably connected to the support arm 23 and driven by a driving source such as a cylinder, an electric push rod or an electromagnet. When it is necessary to adjust the rotation center of the ball bin 21 to a lower position, the limit block can be driven to retract the support arm 23.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
