Description
Technical Field
The utility model belongs to the technical field of the uneven settlement monitoring technique of earth's surface and specifically relates to a novel earth's surface point protection device.
Background
The ground surface point is a monitoring point buried in the ground surface and used for observing the ground surface settlement. At present, the method is widely applied to construction monitoring of tunnels, foundation pit excavation and uneven settlement of the ground surface around large buildings. In order to prevent the buried ground surface from being damaged by external force or being immersed in rainwater and mud after rainy days, which affects the monitoring work of monitoring personnel, a protection device needs to be additionally arranged on the buried ground surface, but the existing ground surface protection device still has defects in the using process, such as: during measurement, a protective cover plate of the protective device is not easy to directly open by hands, and the protective cover plate needs to be pried by using some tools every time the protective cover plate is opened, so that certain difficulty is caused in measurement; in the service cycle, the existing plane protective cover plate is often crushed by vehicles or other heavy objects, the protective cover plate is often cracked downwards from the middle, and even the surface point settlement device below the protective cover plate is damaged; because the earth's surface settlement monitoring generally has longer cycle, also can take place to sink at this in-process landmark point protection device often along with the time, at this moment the unipolar mode of opening of protection apron will receive the restriction, is blocked by the settlement pore wall of one side, makes the unable normal opening of protection apron, consequently needs a novel earth's surface point protection device.
SUMMERY OF THE UTILITY MODEL
In order to overcome the difficult problem of opening of current earth's surface point protection device protection apron, apron easy fracture, the utility model provides a novel earth's surface point protection device makes the protection apron open more conveniently to the protection apron is firmer behind the atress, is difficult for the fracture.
The utility model adopts the following technical proposal that:
the utility model provides a novel earth's surface point protection device, by the main part, protection apron and novel dead axle connecting piece are constituteed, the main part is provided with the sleeve that thick plastics were made by the high strong of round apron area by the bottom, be provided with bellied serial number digit and square groove on the protection apron, be provided with the stainless steel pull ring in the square groove, the protection apron is made by thick plastics of same high strong, the main part links together through novel dead axle connecting piece with the protection apron, novel dead axle connecting piece comprises three dead axle and two stainless steel sheets, three dead axle is the rotation axis of novel dead axle connecting piece.
Preferably, the stainless steel tab is rotatable 90 ° upwardly.
Preferably, the protective cover plate is made into an arc shape slightly convex upwards.
Preferably, the two stainless steel sheets of the novel dead axle connecting piece can be folded along the middle dead axle in a rotating way.
The utility model has the advantages that: (1) the protective cover plate is provided with a stainless steel pull ring which can rotate upwards by 90 degrees, so that the protective cover plate can be opened quickly when in use. (2) The protective cover plate is made into an arc cover plate slightly protruding upwards so as to prevent the protective cover plate from being damaged by middle depression caused by external force. (3) Two stainless steel sheets of novel dead axle connecting piece can follow the rotatory folding of middle dead axle to this protection device subsides along with the earth's surface hole and leads to the protection apron to be supported by the pore wall in earth's surface hole in the use, make the unable normal opening of protection apron.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the protective cover of the present invention after closing;
FIG. 3 is a side view of the present invention;
fig. 4 is a schematic diagram of the novel dead axle connector.
In the figure, the number of 1 is the number, 2 square grooves, 3 novel dead axle connectors, 4 stainless steel pull rings, 5 protective cover plates, 6 main parts, 7 skirt belts, 8 stainless steel sheets and 9 dead axles.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
the utility model provides a novel earth's surface point protection device, by main part 6, protection apron 5 and novel dead axle connecting piece 3 are constituteed, main part 6 is the sleeve of forcing thick plastics and making by the height that the bottom was provided with round apron 7, be provided with bellied serial number digit 1 and square groove 2 on the protection apron 5, protection apron 5 is forced thick plastics by same height and is made, main part 6 links together through novel dead axle connecting piece 3 with protection apron 5, three dead axle 9 is the rotation axis of novel dead axle connecting piece 3, two stainless steel pieces 8 of novel dead axle connecting piece 3 are in the state of opening in the schematic diagram when protection apron 5 is opened, when protection apron 5 is closed, two stainless steel pieces 8 are folded together along the jackshaft of three dead axle 9.
Be provided with stainless steel pull ring 4 in the square groove 2, stainless steel pull ring 4 can upwards rotate 90 moreover, can directly hold stainless steel pull ring 4 and open protection cover plate 5 when measuring.
The protective cover plate 5 is made into an arc shape which is slightly convex upwards, so that the external force is dispersed to the periphery when the protective cover plate 5 is extruded by the external force, and the protective cover plate 5 is prevented from being directly crushed and cracked.
Two stainless steel sheets 8 of the novel dead axle connecting piece 3 can be folded along the rotation of the middle dead axle 9, and the phenomenon that the protective cover plate 5 cannot be opened after the protection device caused by the traditional connection mode sinks is avoided.
During the use, at first arrange protection device in the earth's surface hole top of burying underground, protection apron 5 is slightly lower than ground, arranges that the back periphery is filled with cement mortar, holds stainless steel pull ring 4 with the hand and opens protection apron 5 when using, and two stainless steel sheets 8 of novel dead axle connecting piece 3 are in the open mode this moment, closes protection apron 5 after the measurement finishes, and two stainless steel sheets 8 of novel dead axle connecting piece 3 are folded together through middle dead axle 9 this moment.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
