Embodiment Construction
[0016] Below in conjunction with accompanying drawing of description, the present invention will be further described.
[0017] Such as figure 1 As shown, a support device for erecting an instrument includes a support platform 1 and three legs 2 arranged at equal intervals at the lower end of the edge of the support platform 1 and connected by hinges. A retractable inner tube 22, the outer tube 21 and the inner tube 22 are fixed by a grip lock 23; the center of the lower surface of the support platform 1 is provided with a branch pipe 3 extending downward, and the outer surface of the branch pipe 3 is There is a casing 4 that can move along the axial direction of the branch pipe 3, and the top end of the casing 4 is fixed with the branch pipe 3 by a fastener. Preferably, a threaded hole 41 is provided on the casing 4, and the casing 4 4 is fixed to the branch pipe 3 by fastening bolts; the end of the casing 4 is provided with a cone-shaped portion 5 for landing on the ground,...

The invention discloses a supporting device for instrument erection. The supporting device comprises a supporting platform and three supporting legs, wherein the three supporting legs are arranged at the lower end of the edge of the supporting platform at equal intervals. Each supporting leg comprises an outer pipe and a telescopic inner pipe, wherein the inner pipe is sleeved with the outer pipe, and the outer pipe and the inner pipe are fixed with a holding type locking part. The center of the lower surface of the supporting platform is provided with a supporting pipe extending downwards. The outer surface of the supporting pipe is sleeved with a casing pipe capable of moving in the axial direction of the supporting pipe. The top end of the casing pipe is fixed to the supporting pipe through a fastener, and the tail end of the casing pipe is provided with a conical body portion used for touchdown. The conical body portion is of a conical body structure, and the bottom face of the conical body is provided with an anti-skid layer. The supporting device for instrument erection is simple in structure, convenient to use, high in universality and capable of overcoming the skid phenomenon and ensuring stability, facilitates measurement, and is particularly suitable for being used in the smooth ground and other places such as construction sites, thereby achieving the dual-purpose purpose.
Description
technical field [0001] The invention relates to a support frame, in particular to a support device for erecting instruments. Background technique [0002] When the surveying and mapping instrument is used, it needs a bracket to support it. The surveying and mapping instrument is placed on the supporting platform on the bracket, and is supported by three legs on the lower part of the supporting platform. [0003] The existing support frame adopts a triangular structure composed of three legs, which is very stable, and is very suitable for places such as construction sites. When in use, the sharp ends of each leg can be directly inserted into the ground surface, so that the support frame is firmly fixed. However, if it is used on smooth ground or slippery and hard rocks, it is very limited, not only easy to slip, but also not stable enough, which will cause inconvenience in use. Contents of the invention [0004] The main purpose of the present invention is to overcome the ...
