Abstract
The utility model discloses a scalable levelling rod handrail of moving of tearing open, including splint I, splint II, telescopic link and handle, telescopic link one end is connected with splint II, and the other end is connected with the handle, the bolt hole has been seted up in splint I and II four corners of splint to through bolted connection, and press from both sides tight levelling rod both sides. The utility model is convenient and fast to use, which not only ensures the safety, but also improves the working efficiency; the technical problems of unsafe and inconvenient tank bottom surveying and mapping of a surveyor are solved.
Description
Technical Field
The utility model relates to an engineering measuring equipment field, concretely relates to scalable levelling rod handrail of tearing open and moving.
Background
The depth of a sewage ditch for burying sewage pipes in a community is about two meters, the width of the sewage ditch is about more than one meter, and when a digger excavates the sewage ditch in the community, surveying and mapping personnel are generally required to find points at the bottom of a groove and right a leveling rod, and whether the bottom of the groove is excavated to a designed elevation is measured through a level gauge on the ground. In this kind of common construction of measurement while digging, there is huge potential safety hazard: the soil body just excavated is disturbed and easy to collapse; the bottom of the tank is uneven, and sometimes the bottom of the tank has water, so that the movement is unchanged; the construction is not standardized, so that soil bodies on two sides of the groove collapse into the groove under the action of lateral pressure. These can cause damage to the survey crew at the bottom of the tank. We receive a plurality of industrial accident cases, and impel us to study whether workers can complete surveying and mapping work without being placed at the bottom of the tank, so that safety is guaranteed and work is completed.
SUMMERY OF THE UTILITY MODEL
In view of the deficiencies in the prior art, the utility model provides a but scalable levelling rod handrail of tearing open move to it is unsafe, inconvenient technical problem to solve tank bottom survey and drawing.
In order to solve the technical problem and achieve the purpose of the invention, the utility model adopts the following technical scheme: the utility model provides a scalable levelling rod handrail of moving of tearing open, includes splint I, splint II, telescopic link and handle, telescopic link one end is connected with splint II, and the other end is connected with the handle, the bolt hole has been seted up in splint I and II four corners of splint to through bolted connection, and press from both sides tight levelling rod both sides.
Further, the inner sides of the clamping plate I and the clamping plate II are both provided with rubber pads.
Furthermore, the two telescopic rods are arranged on the middle line of the clamping plate II and distributed up and down, the small ends of the two telescopic rods are connected with the clamping plate II, and the large ends of the two telescopic rods are connected with the handle.
Compared with the prior art, the beneficial effects of the utility model are that:
the clamp plate I and the clamp plate II are connected through bolts, and can be conveniently detached and moved, any position of the clamping leveling rod (two side faces without characters of the clamping leveling rod) is removed, and the telescopic rod is stretched through the handle, so that a worker can stand on the ground beside the groove to find a point to be measured and straighten the leveling rod at the bottom of the groove. In a word, the utility model discloses convenient to use is swift, has guaranteed safety promptly, has improved work efficiency again.

In the figure: 1-splint I, 2-splint II, 3-telescopic rod, 4-handle and 5-leveling rod.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and embodiments of the present invention include, but are not limited to, the following examples.
As shown in fig. 1 to 4, the utility model provides a scalable levelling rod handrail of tearing open and move, including splint I1, splint II 2, telescopic link 3 and handle 4, 3 one ends of telescopic link are connected with splint II 2, and the other end is connected with handle 4, the bolt hole has been seted up in splint I1 and II 2 four corners of splint to through bolted connection, and press from both sides tight levelling rod both sides.
In order to increase the friction force between the contact surfaces of the clamping plates I1 and II 2 and the leveling rod and avoid hurting the side surface of the leveling rod, rubber pads are arranged on the inner sides of the clamping plates I1 and II 2.
Preferably, the number of the telescopic rods 3 is two, the two telescopic rods 3 are arranged on the middle line of the clamping plate II 2 and distributed up and down, the small ends of the telescopic rods are connected with the clamping plate II 2, and the large ends of the telescopic rods are connected with the handle 4. The telescopic rod 3 is connected with the clamping plate II 2 and the handle 4 and can adopt a plurality of existing fixed connection modes such as integral forming or welding and the like. The material can be selected from plastic or metal, etc. which have high strength and light weight.
When the measuring and drawing device is used, a surveying and drawing person stands on the ground beside a groove, clamps the handrail of the structure at the proper position of the leveling rod (clamps two side surfaces of the leveling rod without characters) according to the design depth of the sewage groove, finds a measuring point at the bottom of the groove, holds the upper end of the leveling rod, obliquely sends the bottom of the leveling rod to the measuring point at the bottom of the groove, stretches the handle 4, holds the handle 4 to right the leveling rod, and measures; after the point is measured, the leveling rod is pulled to the side through the handle 4, the leveling rod is held by hand, the next point is measured, and the measurement is repeatedly finished.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
