Detailed implementation manners

[0029] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0030] As Figures 1-11 shown, the present invention provides a surveying and mapping device for river engineering, including a telescopic rod. A support device is provided at the lower end of the telescopic rod. The support device includes a square sleeve 3 that can move up and down. The support device further includes a plurality of expansion support bases 5. When the square sleeve 3 moves up and down, a structure in which the plurality of expansion support bases 5 can turn upward and close or turn downward and unfold is formed; a support plate 9 is provided at the upper end of the telescopic rod. A tray 10 is provided at the upper end of the support plate 9. A fixing device that cooperates with the tray 10 is further provided at the upper end of the support plate 9. When the fixing device is opened, the tray 10 can be fixed. When the fixing device is closed, the tray 10 can move at multiple angles. The fixing device includes a cross plate 29 that can move up and down. When the cross plate 29 moves downward, a structure in which the fixing device is closed and the tray 10 can be adjusted at multiple angles is formed.

[0031] As Figures 1-7As shown in the figure, surveying instruments such as total stations or levels are installed at the upper end of the tray 10. The telescopic rod can be telescoped up and down to adjust the height of the tray 10 and the total station. The telescopic rod can also support and fix the entire device. The total station is a prior art and will not be elaborated here. The support device can strengthen and support the telescopic rod. By placing the device at a designated position and driving the square sleeve 3 to move downward, the expansion support base 5 can be turned downward and unfolded, thereby increasing the contact with the ground and making the device more stable. When storage is required, driving the square sleeve 3 to move upward can make the expansion support base 5 turn upward and close, so that the support device is folded up and does not occupy space during storage. The support plate 9 supports and fixes the tray 10, the fixing device, etc. Through the cooperation of the set tray 10 and the fixing device, when the cross plate 29 moves downward, the fixing device can be closed. At this time, the tray 10 can be turned forward, backward, left or right for multi-angle adjustment. When the cross plate 29 moves upward, the fixing device can be opened. At this time, the tray 10 is in a fixed state after being adjusted to an appropriate angle, with a multi-degree-of-freedom adjustment function, adapting to different occasions and improving the surveying accuracy and efficiency.

[0032] The telescopic rod includes an outer cylinder 1 and an inner rod 2. The inner rod 2 is slidably connected to the inner wall of the outer cylinder 1. The square sleeve 3 is slidably connected to the outer surface of the outer cylinder 1. The left and right inner walls of the square sleeve 3 are respectively slidably connected with a first latch 6. The lower sides of the left and right surfaces of the outer cylinder 1 are respectively provided with lower card slots 38 that cooperate with the first latch 6, and the upper sides of the left and right surfaces of the outer cylinder 1 are respectively provided with upper card slots 39 that cooperate with the first latch 6.

[0033] As Figures 1-3 、 Figure 11 As shown in the figure, the inner rod 2 can be slidably connected to the inner wall of the outer cylinder 1 up and down, that is, the telescopic rod can be telescoped up and down to change its length. The square sleeve 3 can be slidably connected to the outer surface of the outer cylinder 1 up and down. The first latch 6 can be slidably connected to the inner wall of the square sleeve 3 left and right. When the first latch 6 meshes with the lower card slot 38 or the upper card slot 39, the position of the square sleeve 3 can be fixed, thereby fixing the position of the expansion support base 5. When the first latch 6 meshes with the inner wall of the lower card slot 38, the square sleeve 3 is at the lowest position at this time, and the corresponding expansion support base 5 is in the unfolded state. When the first latch 6 meshes with the inner wall of the upper card slot 39, the square sleeve 3 is at the highest position at this time, and the corresponding expansion support base 5 is in the closed state.

[0034] First handles 7 are respectively fixedly connected to the outer side ends of the two first latches 6, and tension springs 8 that cooperate with the first handles 7 are respectively sleeved on the outer surfaces of the first latches 6.

[0035] As Figure 11As shown, one end of the tension spring 8 is fixedly connected to the square sleeve 3 respectively, and the other end of the tension spring 8 is fixedly connected to the first handle 7 respectively. The tension spring 8 always has an inward pulling force on the first handle 7 and the first latch 6, so that the first latch 6 can be stably engaged with the upper card slot 39 or the lower card slot 38 under normal conditions and will not disengage; when driving the two first handles 7 to move outward, the first latch 6 can be driven to move outward, so that the first latch 6 disengages from the lower card slot 38. At this time, the square sleeve 3 can move up and down, that is, control the expansion or closing of the expansion support base 5.

[0036] The expansion support bases 5 are respectively hinged to the lower sides of the front, rear, left and right end faces of the outer cylinder 1. Four evenly distributed first connecting rods 4 are also hinged to the outer side end face of the square sleeve 3, and the lower ends of the first connecting rods 4 are respectively hinged to the corresponding expansion support bases 5.

[0037] As Figure 11 shown, when the square sleeve 3 moves upward, it can drive the upper end of the first connecting rod 4 to move upward, and the lower end of the first connecting rod 4 will drive the expansion support base 5 to turn upward, so that the expansion support base 5 is closed. When the square sleeve 3 moves downward, it can drive the upper end of the first connecting rod 4 to move downward, and the lower end of the first connecting rod 4 will drive the expansion support base 5 to turn downward, so that the expansion support base 5 is expanded for use.

[0038] The cross plate 29 is slidably connected to the inner wall of the upper end of the inner rod 2. Two second latches 36 are provided at the lower end of the inner rod 2. A plurality of second card slots 37 are respectively opened on the front and rear end surfaces of the outer cylinder 1 and are matched with the second latches 36. When the cross plate 29 moves downward, a structure can be formed in which the two second latches 36 move inward and disengage from the second card slots 37.

[0039] As Figures 8-9 shown, the cross plate 29 can be slidably connected to the inner wall of the upper end of the inner rod 2 up and down. Through the engagement of the second latch 36 and the second card slot 37, the overall height of the telescopic rod can be restricted. Through the plurality of second card slots 37 provided, the height of the telescopic rod can be adjusted in multiple gears. When the cross plate 29 moves downward, the second latch 36 can also move inward. When the second latch 36 moves inward, it can disengage from the second card slot 37. At this time, the telescopic rod can adjust its height, and the fixing device can be closed to perform multi-angle adjustment on the tray 10, and the height and multi-angle of the tray 10 can be adjusted simultaneously, further improving the adjustment efficiency and accelerating the working process.

[0040] A long rod 31 is fixedly connected to the lower end surface of the cross plate 29, a guide seat 32 is fixedly connected to the lower end surface of the long rod 31, the second latches 36 are respectively slidably connected to the inner walls of the front and rear ends of the inner rod 2, and first sliding pins 34 are respectively fixedly connected to the inner side end faces of the two inner rods 2. First inclined slots 33 are respectively opened on the guide seat 32 and are matched with the first sliding pins 34.

[0041] As Figures 8-9As shown, the second latch 36 can slide back and forth on the inner wall of the inner rod 2, that is, the two second latches 36 can move inward or outward; through the connection of the long rod 31 with the guide seat 32 and the cross plate 29, when the cross plate 29 moves up and down, it can drive the guide seat 32 to move up and down. Support seats 35 are fixedly connected to the inner end faces of the two second latches 36 respectively, and the first sliding pin 34 is fixedly connected to the inner wall of the support seat 35, which is equivalent to the first sliding pin 34 being fixedly connected to the second latch 36; through the engagement of the first inclined groove 33 and the first sliding pin 34, when the cross plate 29 and the guide seat 32 move downward, it can drive the two first sliding pins 34 to move inward, and when the first sliding pin 34 moves inward, it can drive the support seat 35 and the second latch 36 to move inward. Similarly, when the cross plate 29 and the guide seat 32 move upward, it can drive the two first sliding pins 34 to move outward and the second latch 36 to move outward, thereby controlling the engagement or disengagement of the second latch 36 with the second card slot 37.

[0042] A ball rod 11 is fixedly connected to the inner wall at the center of the support disk 9. The upper end of the ball rod 11 is fixedly connected to a ball pin 12. A concave seat 13 that cooperates with the ball pin 12 is fixedly connected to the center of the lower surface of the tray 10. A track plate 14 is also fixedly connected to the lower surface of the tray 10. A threaded rod 17 that can move up and down is installed on the support disk 9. The upper surface of the threaded rod 17 is fixedly connected to an extension seat 16, and a third sliding pin 15 is fixedly connected to the inner wall of the extension seat 16. A long key groove that cooperates with the third sliding pin 15 is formed on the track plate 14.

[0043] As Figures 4-6 shown, the ball rod 11 is used to support and fix the ball pin 12. The ball pin 12 is installed on the inner wall of the concave seat 13. Through the mutual cooperation of the ball pin 12 and the concave seat 13, it is equivalent to the tray 10 being ball-jointed to the upper end of the ball rod 11, that is, through the ball joint, the tray 10 can be flipped and swung back and forth or left and right; the installation and shape of the track plate 14, the third sliding pin 15, and the extension seat 16 are as Figure 5 shown. Through the engagement of the third sliding pin 15 and the long key groove, when the threaded rod 17 moves up and down, it can drive the extension seat 16 and the third sliding pin 15 to move up and down. When the third sliding pin 15 moves up and down, through the engagement with the long key groove, it can drive the track plate 14 and the tray 10 to flip up or down, thereby adjusting the front and back flip angle of the tray 10.

[0044] A connection seat 30 is slidably connected to the lower surface of the support disk 9. An L-shaped seat 18 is fixedly connected to the front surface of the connection seat 30. A limit rod 19 is fixedly connected to the inner wall of the L-shaped seat 18. The threaded rod 17 is slidably connected to the outer surface of the limit rod 19. An incomplete threaded seat 20 that can move back and forth and cooperate with the threaded rod 17 is slidably connected to the upper surface of the L-shaped seat 18.

[0045] As Figures 5-7As shown, the connecting seat 30 can slide circumferentially on the inner wall of the lower end of the support disk 9. The L-shaped seat 18 supports and fixes the limiting rod 19 and the incomplete threaded seat 20. The threaded rod 17 can slide up and down on the outer surface of the limiting rod 19. The limiting rod 19 can limit the threaded rod 17 to move only up and down. The incomplete threaded seat 20 can slide back and forth on the upper surface of the L-shaped seat 18. When the incomplete threaded seat 20 moves forward to the top position, it can engage with the threaded rod 17. After the incomplete threaded seat 20 engages with the threaded rod 17, it can limit the threaded rod 17 from moving up or down, so that the threaded rod 17 is fixed and the angle of the tray 10 is fixed. When the incomplete threaded seat 20 moves backward, it can disengage from the threaded rod 17. At this time, the threaded rod 17 can move up and down to adjust the angle of the tray 10. When the L-shaped seat 18 and the connecting seat 30 move circumferentially, they can drive the threaded rod 17, the incomplete threaded seat 20, etc. to move circumferentially. When the threaded rod 17, the third sliding pin 15, the track plate 14, etc. move circumferentially, they can drive the tray 10 to rotate. After the tray 10 rotates to a specified angle and then the threaded rod 17 is driven to move up and down, the deflection direction of the tray 10 can be changed, so as to control the front-back deflection or left-right deflection of the tray 10. And there is a certain friction under the sliding connection between the connecting seat 30 and the support disk 9. That is, when the L-shaped seat 18 and the connecting seat 30 are not driven to move circumferentially, the L-shaped seat 18 and the threaded rod 17 can be stable at the specified position, that is, the tray 10 is stable at the specified angle.

[0046] A ring seat 26 that can move up and down is slidably connected to the outer surface of the cue 11. A connecting ring 25 is rotatably connected to the outer surface of the ring seat 26. An extension plate 24 is provided at the front end of the connecting ring 25. A vertical seat 21 is fixedly connected to the upper surface of the incomplete threaded seat 20. A second sliding pin 22 is fixedly connected to the inner wall of the upper end of the vertical seat 21. A second inclined groove 23 that matches the second sliding pin 22 is formed on the extension plate 24.

[0047] As Figure 6As shown, the circular ring seat 26 can move up and down on the outer surface of the cue 11. It is rotationally connected to the circular ring seat 26 through the connecting ring 25. When the circular ring seat 26 moves up and down, it can drive the connecting ring 25 and the extension plate 24 to move up and down. And when the incomplete threaded seat 20, the vertical seat 21, the second sliding pin 22, and the extension plate 24 move circumferentially, it can drive the connecting ring 25 to move circumferentially. The two movements do not affect each other, and the connecting ring 25 and the extension plate 24 can always remain meshed with the second sliding pin 22. When the circular ring seat 26 moves up and down, it can drive the connecting ring 25 and the extension plate 24 to move up and down. When the extension plate 24 moves downward, through the engagement of the second inclined groove 23 and the second sliding pin 22, it will drive the second sliding pin 22, the vertical seat 21, and the incomplete threaded seat 20 to move backward. When the incomplete threaded seat 20 moves backward, it can disengage from the threaded rod 17. Similarly, when the extension plate 24 moves upward, it can drive the incomplete threaded seat 20 to move forward. When the incomplete threaded seat 20 moves forward, it can engage with the threaded rod 17 to fix the position of the threaded rod 17.

[0048] Four guide rods 28 which are evenly distributed and slidably connected to the support disk 9 are fixedly connected to the lower end surface of the circular ring seat 26. The lower ends of the guide rods 28 are respectively fixedly connected to the cross plate 29. A first spring 27 which is matched with the circular ring seat 26 is also sleeved on the outer surface of the cue 11.

[0049] As Figure 6 shown, the guide rods 28 penetrate through the support disk 9 and are slidably connected to the inner wall of the support disk 9 up and down. When the cross plate 29 moves up and down, it can drive the guide rods 28 and the circular ring seat 26 to move up and down. The first spring 27 always has an upward elastic force on the circular ring seat 26, so that the circular ring seat 26 is in the topmost position under normal conditions, and the incomplete threaded seat 20 is in the foremost position under normal conditions and can stably engage with the threaded rod 17 to fix the position of the threaded rod 17. When adjustment is required, by driving the cross plate 29 to move downward, it can drive the two second locking pins 36 to move inward and disengage from the second locking grooves 37, and can also drive the incomplete threaded seat 20 to move backward and disengage from the threaded rod 17. At this time, the height, forward and backward deflection, or left and right deflection angles of the tray 10 can be adjusted, and the multi-degree-of-freedom adjustment is carried out simultaneously, improving the adjustment efficiency and accelerating the working process. When the cross plate 29 is released, under the elastic force of the first spring 27, the circular ring seat 26 and the cross plate 29 can move upward to reset, that is, the two second locking pins 36 move outward again and engage with the second locking grooves 37 to fix the height of the tray 10, and the incomplete threaded seat 20 moves forward to fix the threaded rod 17. At this time, the position of the tray 10 is in a fixed state and can be used normally.

[0050] When the present invention is in use, by placing the device at a designated position and driving the square sleeve 3 to move downward, the expansion support seat 5 can be turned downward and unfolded, thereby increasing the contact with the ground and making the device more stable. When storage is required, by driving the square sleeve 3 to move upward, the expansion support seat 5 can be turned upward and closed, so that the support device is folded, and no space is occupied during storage; with the cooperation of the tray 10 and the fixing device provided, when the cross plate 29 moves downward, the fixing device can be closed. At this time, the tray 10 can be turned forward and backward or left and right for multi-angle adjustment. When the cross plate 29 moves upward, the fixing device can be opened. At this time, the tray 10 is in a fixed state after being adjusted to a suitable angle, having a multi-degree-of-freedom adjustment function, adapting to different occasions, and improving the mapping accuracy and efficiency.
