Description

Technical Field

[0001] The utility model relates to a bracket, in particular to a tripod. Background Art

[0002] The main pump is located in the heart of the nuclear island. It is used to pump hot water into the evaporator to convert heat energy. It is the key to controlling the water circulation of nuclear power operation. The shape of the main pump casing is complex and the size is large. After the pump casing blank is free-forged, it is necessary to use a 3D scanner to scan the entire surface to compare it with the theoretical digital model to determine whether the blank margin is appropriate. When scanning the pump casing blank, due to the large size of the pump casing, it is necessary to change the station by moving the position and orientation of the tracker multiple times to complete the scanning of the entire pump casing surface. Although the traditional tripod can adjust the height of the instrument on the tripod by adjusting the length of its legs, it generally requires manual adjustment, and the traditional tripod does not have a rotation function, which is not convenient for adjusting the direction of the entire instrument. It is extremely inconvenient to use it for 3D scanning and cannot meet the requirements of 3D scanning. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2As shown, a tripod of the utility model comprises a tripod body 1, a rotation drive device 3, an equipment mounting platform 4 and a lifting and adjusting device 2 for adjusting the height of the equipment mounting platform 4, wherein the equipment mounting platform 4 is arranged above the tripod body 1, the lifting and adjusting device 2 is installed on the tripod body 1, and one end of the lifting and adjusting device 2 is connected to the equipment mounting platform 4, a rotatable turntable 5 is provided between the equipment mounting platform 4 and the lifting and adjusting device 2, the equipment mounting platform 4 is connected to the lifting and adjusting device 2 via the turntable 5, and the rotation drive device 3 is connected to the turntable 5 to drive the turntable 5 to rotate.

[0020] The lifting and lowering adjustment device can be provided with a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod, etc. The rotary drive device generally adopts a servo motor. The turntable 5 can directly adopt an existing electric drive turntable.

[0021] The tripod of the utility model can mount a three-dimensional scanning device on an equipment mounting platform 4. During scanning, the height of the equipment mounting platform 4 on the tripod body 1 can be adjusted by the lifting adjustment device 2 as needed, thereby adjusting the height position of the scanning device. The turntable 5 can be driven to rotate by the rotating drive device 3, thereby adjusting the direction of the scanning device. The utility model is easy to use and meets the requirements for three-dimensional scanning.

[0022] In some embodiments, the tripod body 1 includes a center block 12 and legs 11 arranged around the center block 12, and the legs can be fixedly connected or hingedly connected to the center block 12. In the embodiment of the utility model, the tripod body 1 includes a center block 12 and three legs 11 hingedly arranged around the center block 12, and also includes an angle adjustment mechanism for adjusting the support angle of the legs 11. The above structure can be based on actual conditions, such as: when the scanning device is heavy, the angle of the legs 11 can be adjusted by the angle adjustment mechanism so that the legs are at a larger support angle position to better support the device. Among them, the legs are preferably retractable legs with adjustable length, so that when the bottom surface is uneven, the length of each leg can be adjusted according to the position of each leg to make the equipment installation platform level. The legs are preferably retractable legs with adjustable length. The existing structure includes a plurality of rods, which are sequentially plugged and slidably matched to form legs, and adjacent rods are provided with locking members for locking the relative positions of the two, such as latches, locking screws or locking nuts.

[0023] In order to make the legs 11 contact with the bottom surface better, Figure 4 As shown, a universal foot 13 is provided at the lower end of the support leg 11 .

[0024] like Figure 3As shown, the angle adjustment mechanism in the utility model includes a screw sleeve 8 and a threaded rod 6 that cooperates with the thread of the screw sleeve 8. The threaded rod 6 is vertically mounted on the central block 12 and can be rotated around its axis. The screw sleeve 8 is sleeved on the threaded rod 6 through its thread. The screw sleeve 8 is provided with a connecting rod 9 for driving the supporting legs 11 to rotate around their hinge points. The connecting rod 9 is arranged in a one-to-one correspondence with the supporting legs 11. One end of the connecting rod 9 is hinged to the screw sleeve 8, and the other end is hinged to the corresponding supporting leg 11. In this way, rotating the threaded rod 6 can make the screw sleeve 8 on the threaded rod 6 move upward or downward along the threaded rod 6, and during the movement of the screw sleeve 8, the corresponding supporting legs 11 can be driven to rotate synchronously around their hinge points through the connecting rod 9 to adjust the angle of each support so that it is in a suitable support angle position to ensure the support stability of the tripod.

[0025] In some embodiments, the angle adjustment mechanism is a motor that is transmission-connected to the leg 11 to drive it to rotate around a hinge point.

[0026] In the embodiment of the utility model, the lifting and adjusting device 2 is an electric telescopic rod. When it is an electric telescopic rod, it can be fixed on the central block 12. In the utility model, Figure 1 and Figure 2 As shown, the electric telescopic rod is installed in a vertical hole 61 provided in the threaded rod 6 through its outer tube, and is slidably matched with the vertical hole 61. The threaded rod 6 is provided with a locking member 63 for locking the position of the outer tube of the electric telescopic rod. In this way, the height of the electric telescopic rod can be adjusted up and down relative to the threaded rod 6 as needed, so that the height of the equipment mounting platform 4 and the equipment can be adjusted in a wider range. When the electric telescopic rod is adjusted, it can be locked in the vertical hole 61 by the locking member 63.

[0027] The locking member 63 may be a screw or a latch etc. arranged on the threaded rod 6. Figure 3 As shown, in the utility model, the side wall of the open end of the vertical hole 61 is provided with a vertical groove 62, and the locking member 63 is a locking nut sleeved on the setting end of the vertical groove 62 of the threaded rod 6, and the locking nut is threadedly matched with the threaded rod 6 through a tapered thread. In this way, the locking nut can be rotated to squeeze or release the vertical groove 62 through its tapered thread, making it smaller or open, thereby adjusting the size of the open end of the vertical hole 61, and then the outer tube of the electric telescopic rod can be clamped or loosened. The above structure can better lock and fix the electric telescopic rod, and it is not easy to cause the electric telescopic rod to deform.

[0028] In order to facilitate driving the rotation drive device 3 and the electric telescopic rod, the utility model is also provided with a battery 14 and a controller on the tripod body 1. Among them, the controller can be a remote controller that can be wirelessly connected to a remote controller.
