Abstract
Description
Technical Field
[0001] The utility model relates to the field of bar clamping and fixing, and particularly to a fixing device for a radar level gauge. Background Art
[0002] For large brine pools, salt dissolving pools, sewage collection pools, etc., the liquid stored inside needs to be monitored in real time for the change of its liquid level height (volume change). Therefore, a radar level gauge is generally used as the liquid level height detection device. Specifically, the radar level gauge is extended directly above the pool and faces the liquid level of the pool.
[0003] When the radar level gauge needs to be maintained, it needs to be moved from directly above the pool to outside the pool or repaired directly above the pool. However, due to the relatively deep depth of large brine pools, salt dissolving pools, sewage collection pools, etc., generally, the method of moving it to outside the pool is adopted. Currently, for the movement of the fixed radar level gauge, the method of laying it down is generally used. This method can realize laying down the radar level gauge to the outside of the pool, which is convenient for personnel to repair. However, there is a problem that since the pole for fixing the radar level gauge has a certain height, it is difficult to control the pole during the process of laying it down and resetting it to the vertical position. When there are fewer personnel or devices for preventing it from falling and making it vertical, the pole is prone to tipping over, and when there are more personnel or devices, the workload is greatly increased. Summary of the Utility Model
[0004] In view of the above-mentioned defects of the prior art, the purpose of the present utility model is to provide a fixing device for a radar level gauge, which can quickly move the radar level gauge to the outside of the pool for convenient maintenance.

[0007] A fixing base;
[0008] A bottom pipe, arranged on the fixing base, with a limiting perforation and a fixed-angle perforation on its side surface;

[0045] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments
[0046] Embodiment 1:
[0047] As Figures 1 to 12 shown
[0048] The radar level gauge fixing device includes:
[0049] Fixed seat
[0050] Bottom pipe 1, which is arranged on the fixed seat, and its side is provided with a limit perforation 11 and a fixed-angle perforation 12
[0051] Limit pin 2, which is inserted into the limit perforation 11
[0052] Fixed-angle pin 3, which is inserted into the fixed-angle perforation 12
[0053] Inner column 4, which is sleeved inside the bottom pipe 1, and its lower end surface abuts against the limit pin 2; several angle holes 41 arranged in a uniform circumferential array around the axis of the inner column 4 are provided at the horizontal height of the inner column 4 facing the fixed-angle perforation 12; the fixed-angle pin 3 passes through a certain angle hole 41 to limit the rotation of the inner column 4 in the bottom pipe 1
[0054] Cross bar 5, whose tail end is connected to the top end of the inner column 4, and the axis of the cross bar 5 is perpendicular to the axis of the inner column 4
[0055] Mounting plate 6, which is arranged at the head end of the cross bar 5 and is used for installing and fixing the radar level gauge
[0056] The radar level gauge adopts a fixing method where the inner column 4 and the cross bar 5 are fixed together. The inner column 4 is limited in the vertical downward direction with the bottom tube 1, so that the height of the radar level gauge remains constant. At the same time, after removing the fixed-angle pin 3, the inner column 4 can rotate freely within the bottom tube 1. In this way, the cross bar 5 can be rotated to the outside of the pool, and thus maintenance personnel can use a ladder to achieve rapid maintenance. After the maintenance is completed, rotate the inner column 4 back to its original position and then fix it with the fixed-angle pin 3. The entire process can be completed by a single person, and it is safe.
[0057] In this embodiment, a plurality of groups of limit perforations 11 and fixed-angle perforations 12 are provided on the bottom tube 1; each group of limit perforations 11 and fixed-angle perforations 12 are independently and spaced apart from each other.

[0062] Setting multiple slewing bearings 14 can improve the limiting effect on the inner column 4, and at the same time greatly reduce the rotation resistance during rotation, enabling a single worker to rotate the inner column 4.
[0063] In this embodiment, a thrust bearing 42 is provided at the lower end of the bottom tube 1; a shock-absorbing rubber pad 43 is provided at the lower end of the thrust bearing 42.
[0064] The thrust bearing 42 can reduce the resistance during rotation. At the same time, when the inner column 4 is inserted into the bottom tube 1, the shock-absorbing rubber pad 43 can reduce the impact of the inner column 4 on the limit pin 2 and prevent the limit pin 2 from bending and deforming.
[0065] In this embodiment, the fixed seat includes:
[0066] A back plate 81, which is arranged on the side of the bottom tube 1;
[0067] The clamping plate 82 is connected to the back plate 81 by bolts 72 ; a gap is left between the back plate 81 and the clamping plate 82 for the clamped object to pass through, and the back plate 81 , the clamping plate 82 and the clamped object are fixed together by a hoop bolt 84 .

[0070] There are at least two hoops 84 , which are respectively located above and below the upper crossbar 5 of the railing 83 .
[0071] Using the railing 83 as the clamped object can avoid damage to existing structures or equipment, and the above design requirements can ensure the stability of the connection with the railing 83.
[0072] In this embodiment, the surfaces of the back plate 81 and the clamping plate 82 facing the clamped object are provided with a groove 85 having the same shape as the clamped object; the outer contour of the groove 85 is larger than the outer contour size of the clamped object; and the groove 85 is filled with a shock-absorbing layer 86.
[0073] The groove 85 is provided and the shock-absorbing layer 86 is filled in the groove 85 to increase the clamping effect on the railing 83 and avoid loosening and shaking.
[0074] The radar level gauge fixing device of this embodiment is used as follows: the back plate 81 and the clamping plate 82 are aligned with the structure of the railing 83, and then the back plate 81, the clamping plate 82 and the railing 83 are fixed together using the hoop bolt 84.
[0075] Install the radar level meter on the mounting plate 6, and then insert the limit pin 2 into the limit through-hole 11 at the appropriate position on the bottom tube 1 according to the height of the inner column 4, and then insert the inner column 4 into the bottom tube 1 until the shock-absorbing rubber pad 43 is completely against the limit pin 2, and then rotate the inner column 4 so that the angle hole 41 on the inner column 4 is aligned with the fixed angle through-hole 12 on the bottom tube 1, and then insert the fixed angle pin 3, and the installation of the entire device is completed.
[0076] When maintenance is needed, pull out the fixed angle pin, rotate the inner column 4, so that the radar level meter is located on the ground outside the pool, then plug in the fixed angle pin 3 to lock the rotation angle of the inner column 4. Finally, use a ladder or other climbing tools to repair the radar level meter. After the maintenance is completed, pull out the fixed angle pin 3, rotate the inner column 4 to reset it, and then plug in the fixed angle pin 3.
