Abstract
The utility model discloses a levelling rod, including the levelling rod body, fixing device and rotary device, fixing device establishes the lock ring in levelling rod body periphery including the cover, lock ring and levelling rod body reciprocal anchorage, and the below of lock ring is equipped with a plurality of free bearing, and articulated on the free bearing have branch, and the both ends of branch lean on with levelling rod body and ground counterbalance respectively, and rotary device is including locating the fixed station of levelling rod body below, and the fixed station internal rotation is connected with the revolving stage, and the levelling rod body is placed on the revolving stage, fixes through the fixed block between revolving stage and the fixed station. The utility model discloses can rotate and can keep balance.
Description
Technical Field
The utility model belongs to the technical field of measuring tool technique and specifically relates to a levelling rod is related to.
Background
Leveling, also known as geometric leveling, is a method of measuring the difference in height between two points on the ground using a level gauge and a leveling rod. A level is arranged between two points on the ground, a leveling staff erected on the two points is observed, and the height difference between the two points is calculated according to the reading on the staff. The elevation of each point is typically determined from station to station along a selected leveling route, starting from the leveling origin or any known elevation point. The inconvenient regulation of angle of current levelling rod, and in case carry out the regulation of angle, just make level measurement chi lose the levelness easily to because the length of levelling rod is longer, hardly oneself keep balance, need the staff to hand the levelling rod normally and can normally carry out the operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art not enough, provide a levelling rod.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a leveling rod, including the leveling rod body, fixing device and rotary device, fixing device establishes the lock ring in leveling rod body periphery including the cover, lock ring and leveling rod body reciprocal anchorage, the below of lock ring is equipped with a plurality of free bearing, it has branch to articulate on the free bearing, the both ends of branch lean on with leveling rod body and ground counterbalance respectively, rotary device is including locating the fixed station of leveling rod body below, the fixed station internal rotation is connected with the revolving stage, the leveling rod body is placed on the revolving stage, fix through the fixed block between revolving stage and the fixed station.
The one end that levelling rod body was kept away from to branch articulates there is the cushion.
The lower part of the cushion block is provided with a rubber layer.
The fixed block is the bolt, is equipped with the locating hole on the fixed station, and in the bolt twists the locating hole, the upper portion of bolt is close to the part of revolving stage and is laminated with the revolving stage each other.
The utility model has the advantages that: according to the angle of survey and drawing, rotate the back to the levelling rod body and fix through the fixed block, can carry out the regulation of three hundred sixty degrees angles to two-sided levelling rod, make things convenient for the multi-angle measurement, and can not influence the levelness of two-sided levelling rod self when adjusting, fix the levelling rod body through branch, reduced artifical work intensity for measure the process, measurement accuracy is high.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the fixing device and the rotating device of the present invention;
in the figure: the leveling rod comprises a leveling rod body 1, a support ring 2, a hinged support 3, a support rod 4, a cushion block 5, a rubber layer 6, a fixed table 7, a rotating table 8 and a fixed block 9.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1-2, the leveling rod comprises a leveling rod body 1, a fixing device and a rotating device, wherein the fixing device comprises a support ring 2 sleeved on the periphery of the leveling rod body 1, the support ring 2 and the leveling rod body 1 are fixed to each other, a plurality of hinge seats 3 are arranged below the support ring 2, one end, away from the leveling rod body 1, of each support rod 4 is hinged with a cushion block 5, the four support rods 4 are uniformly distributed around the leveling rod body 1, the hinge seats 3 are hinged with support rods 4, two ends of each support rod 4 are respectively abutted against the leveling rod body 1 and the ground, the leveling rod body 1 is generally supported by people due to the long length of the leveling rod body 1, and the support rods 4 can replace the people to support the leveling rod body, so that the phenomenon of toppling is avoided, the manual assistance is reduced, and the fixing is reliable;
the rotary device is including locating fixed station 7 of 1 below of levelling rod body, 7 internal rotations of fixed station are connected with revolving stage 8, levelling rod body 1 is placed on revolving stage 8, fix through fixed block 9 between revolving stage 8 and the fixed station 7, fixed block 9 is the bolt, be equipped with the locating hole on the fixed station 7, the bolt twists in the locating hole, the part that the upper portion of bolt is close to revolving stage 8 laminates with revolving stage 8 each other, with rotatory levelling rod body 1 back with the hand, twist the bolt in the locating hole, the upper portion and the revolving stage 8 of bolt laminate each other for revolving stage 8 and fixed station 7 relatively fixed, this structure can carry out the regulation of three hundred sixty degrees angles to two-sided levelling rod, make things convenient for multi-angle measurement, and can not influence the levelness of two-sided levelling rod self during the regulation.
The one end that levelling rod body 1 was kept away from to branch 4 articulates there is cushion 5, the lower part of cushion 5 is equipped with rubber layer 6, can improve the reliability that branch 4 supported levelling rod body 1, avoids skidding.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
