Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, which are provided only for explaining the present invention and are not intended to limit the scope of the present invention.
With reference to fig. 1 and 2, a movable tripod platform comprises a frame plate 1, wherein the bottom of the frame plate 1 is hinged with three telescopic frame legs 2, universal wheels 3 are arranged at the tail ends of the frame legs 2, and positioning devices are arranged on the frame legs 2; the positioning device comprises a positioning rod 4 capable of moving along the axial direction of the frame leg 2, and the universal wheel 3 is higher than the lower limit position of the tail end of the positioning rod 4.
The frame legs 2 are hollow rods, the positioning rods 4 penetrate through the frame legs 2, the occupied space of the tripod platform is reduced, and the structure is more reasonable. The side wall of the frame leg 2 is provided with a through hole 21, and a positioning bolt 22 is arranged in the through hole 21; the positions of the positioning rod 4 near the two ends are respectively provided with an upper positioning hole 23 and a lower positioning hole 24 which are matched with the positioning bolt 22.
In this embodiment, the cross-section of the support legs and the positioning rod is rectangular, so as to ensure that the positioning rod cannot rotate around the central axis of the positioning rod when sliding in the support legs, and ensure that the positioning bolt can be accurately inserted into the upper positioning hole or the lower positioning hole.
The end part of the positioning rod 4 extending out of the tripod leg is formed into a pointed end, so that the contact area between the end part of the positioning rod and the ground (generally, a non-smooth plane such as concrete or soil quality) during working is reduced, and the working stability of the tripod is improved.
The working process of the utility model is as follows:
when the total station works normally, the positioning bolt is inserted into the upper positioning hole of the positioning rod, the tip of the positioning rod is used as the bottom end of the frame leg to be in contact with the ground, and the length of the frame leg can be adjusted to ensure that the frame plate is horizontal and the total station works conveniently;
when the total station needs to be moved in a short distance, the total station does not need to be dismounted from the tripod, the positioning bolts on the three support legs can be sequentially transferred from the upper positioning holes to the lower positioning holes of the positioning rods, the positioning rods are accommodated in the support legs at the moment, the bottom ends of the support legs are in contact with the ground through the universal wheels, and the position of a tripod platform can be adjusted at the moment according to working requirements;
after reaching the designated position, the positioning bolts on the three support legs are sequentially transferred to the upper positioning holes from the lower positioning holes of the positioning rods, and the pointed ends of the positioning rods are used as the bottom ends of the support legs to be in contact with the ground and return to the initial working posture.
In other embodiments of the present application, as shown in fig. 3, the side wall of the frame leg 2 is provided with a through slot 25 arranged axially, and the length of the through slot 25 is smaller than that of the frame leg 2; the two ends of the through groove 25 are both provided with clamping positions 26, and the positioning rod 4 is fixedly connected with an operating handle 27 extending out of the through groove 25.
An extension spring is arranged at the top of the positioning rod 4 in the frame leg 2, and a pedal (not shown in the drawing) is arranged at the tail end of the operating handle 27. The purpose of arranging the pedal is to accord with the operation habit, and related workers can adjust the operating handle without bending down; extension spring's effect lies in, and the locating lever can be withdrawed to the frame leg automatically under extension spring's effect when the operating handle is located logical groove in, and the universal wheel contacts with ground this moment, conveniently shifts the tripod, and the during operation need move the action bars to just can realize terminal and the ground contact of locating lever in the screens that leads to the groove lower extreme.
In this example, the cross-section of the support legs and the positioning rod is circular, because the positioning rod needs to rotate around the central axis of the positioning rod during working, and the operation handle is ensured to be switched in the through groove and the clamping position.
In summary, the preferred embodiments of the present invention are only examples, and the scope of the present invention is not limited thereto, and all equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope covered by the present invention.
