[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0025] Reference Figure 1-3 A support foot for a fixed frame of a measuring instrument for geotechnical engineering investigation, comprising a support 1 and a lifting mechanism and an adjusting mechanism 9 installed on the support 1, the lifting mechanism comprising a support plate 2, a motor 3, a gear 4, a gear column 6 and a support platform 7, the support plate 2 is installed on the support 1 through a sleeve at the bottom, the motor 3 is installed on the support plate 2, the gear 4 is installed at the output end of the motor 3, the gear column 6 penetrates the support plate 2 and is meshed and connected with the gear 4, and the support platform 7 is fixedly installed at the top end of the gear column 6;
[0026] The adjustment mechanism 9 is set in three groups, which are respectively installed at the bottom of the three legs of the bracket 1, including a ring tube 901, a hinge seat 902, a connecting plate 903, a connecting shaft 904, a latch 905 and a stud 906. The ring tube 901 is sleeved at the bottom of the leg of the bracket 1, the hinge seat 902 is installed on the ring tube 901, the connecting plate 903 is rotatably installed on the connecting plate 903 through the connecting shaft 904, the latch 905 penetrates the ear plate of the outer wall of the ring tube 901 and extends through the through hole on the connecting shaft 904, and the stud 906 is rotatably installed on the connecting plate 903 and locked by a nut. The lifting mechanism and the adjustment mechanism 9 can be set separately to facilitate the subsequent disassembly and installation of the staff.
[0027] A battery 5 for providing electrical energy to the motor 3 is also provided on the support plate 2; a shell 8 for protecting the motor 3, the gear 4 and the battery 5 is also provided on the support plate 2; the shell 8 is detachably mounted on the support plate 2, and an opening is also provided on the side wall of the shell 8 to facilitate replenishing power to the battery 5.
[0028] Ear plates are provided on both sides of the ring tube 901, and the latch 905 is two ear plates that penetrate the two sides of the ring tube 901 one by one; multiple through holes are opened around both ends of the connecting shaft 904, and the diameter of the through hole is matched with the diameter of the latch 905; multiple through holes are opened around both ends of the connecting shaft 904, and the connecting shaft 904 can be adjusted to multiple angles according to the terrain, so as to achieve horizontal adjustment and stability of the bracket 1. After adjusting the angle of the connecting plate 903, the latch 905 is inserted through the ear plates on the side of the ring tube 901 and the holes at the ends of the connecting shaft 904 to limit the angle of the connecting plate 903, thereby limiting the movement of the connecting plate 903 again;
[0029] According to the terrain, in order to make the support plate 2 of the device in a horizontal state when placed, the adjustment mechanism 9 under the bracket 1 can be adjusted first. If one of the three legs of the bracket 1 is in a low position, since the connecting plate 903 is vertically arranged with the bracket 1 in the initial state, the stud 906 can be directly rotated to move downward until the bottom of the stud 906 touches the ground, and then the stud 906 is locked by the nut, so that the upper end of the bracket 1 can be adjusted to a horizontal state;
[0030] To ensure that the bracket 1 is stable during use, the studs 906 at the other two legs can be rotated to move downward and contact the ground, and the multi-point support increases the stability of the bracket 1;
[0031] Affected by the terrain, when the terrain is inclined at a high angle, in order to ensure the horizontal placement of the bracket 1, the angle of the connecting plate 903 can be adjusted first, and then the pin 905 can be inserted through the ear plate on the side of the ring tube 901 and the hole at the end of the connecting shaft 904 to limit the angle of the connecting plate 903. (It should be noted that the angle between the connecting plate 903 at a low position and the bracket 1 can be appropriately adjusted to increase. At this time, only a small number of rotating studs 906 are needed to contact the ground to achieve support. The angle between the connecting plate 903 at a high position and the bracket 1 can be appropriately adjusted to reduce to avoid direct contact between the connecting plate 903 and the ground, which affects the normal placement of the bracket 1. Then, the studs 906 can be adjusted to contact the ground. The triangular relationship multi-point support makes the upper end of the device stable after being adjusted to a horizontal state);
[0032] After the adjustment of the bracket 1 is completed, the lifting mechanism can be placed on the bracket 1. At this time, the sleeve at the bottom of the support plate 2 is sleeved on the upper end of the bracket 1 to achieve the installation of the lifting mechanism;
[0033] After the equipment is subsequently placed on the support platform 7, the motor 3 can be driven to drive the gear column 6 to move up and down through the gear 4, and the gear column 6 pushes the support platform 7 to move up and down, so as to adjust the equipment to a height suitable for use by the staff.
[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
