The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example 1:
referring to fig. 1, the safe sun-shading device for the engineering exploration drilling machine comprises a sun-shading net 1, a top fixing rope 4, a pressure limiting pier 6 and an automatic disconnection and connection device, wherein the upper end of the sun-shading net 1 is connected with a drilling machine tower frame 9 through the top fixing rope 4, the pressure limiting pier 6 is arranged on the ground, and the lower end of the sun-shading net 1 is connected with the pressure limiting pier 6 through the automatic disconnection and connection device; the automatic disconnecting device comprises a first magnetic adsorption part 7 and a second magnetic adsorption part 8, and the first magnetic adsorption part 7 and the second magnetic adsorption part 8 are magnetically adsorbed; when the wind resistance of the sunshade net 1 is larger than the magnetic force between the first magnetic adsorption piece and the second magnetic adsorption piece, the first magnetic adsorption piece and the second magnetic adsorption piece are automatically separated.
Preferably, the first magnetic adsorption part 7 and the second magnetic adsorption part 8 are both magnets, or one is a magnet and the other is a steel plate; in this embodiment, the first magnetic attraction member 7 is a magnet, and the second magnetic attraction member 8 is a steel plate.
Preferably, the sunshade net 1 can ventilate, and in the embodiment, the sunshade net is preferably a dark light ventilated polyethylene sunshade net; the wind can be ventilated to reduce the wind resistance generated by the sunshade net, reduce the load borne by the drilling tower and prevent the drilling tower from overturning, and the sunshade net can shield the sunlight for workers and reduce the discomfort of hot weather.
The automatic disconnection device further comprises a lower fixing rope 5; the magnetic adsorption piece I7 and the pressure limiting pier 6 as well as the magnetic adsorption piece II 8 and the lower end of the sunshade net 1 are connected through a lower fixing rope 5; as can be understood by those skilled in the art, the lower fixing ropes 5 and the top fixing ropes 4 are flexible parts, and can adapt to the change of the sunshade net under different wind forces.
Referring to fig. 1, two corners of the upper end of the sunshade net 1 are connected with a rig tower frame 9 through top fixing ropes 4, two corners of the lower end of the sunshade net 1 are connected with pressure limiting piers 6 through automatic disconnection and connection devices respectively, and as shown in fig. 1, the automatic disconnection and connection devices correspond to the pressure limiting piers one by one.
Specifically, the upper end and the lower end of the sunshade net 1 are respectively provided with an ejector rod 2 and a bottom rod 3, and the top fixing rope 4 and the automatic disconnection device are respectively connected to the ejector rod 2 and the bottom rod 3. Further, the top rod 2 and the bottom rod 3 both comprise a plurality of rod section single bodies, and adjacent rod section single bodies are connected through threads. Through threaded connection between the adjacent pole section monomer, can conveniently adjust the length of ejector pin or bottom rod (through the mode that increases, subtracts pole section monomer quantity), can adjust the size of sunshade net according to actual demand.
Further preferably, the ejector rod 2 and the bottom rod 3 are both made of aluminum alloy, the weight of the bottom rod and the ejector rod can be reduced by adopting the aluminum alloy, the load on the drilling machine tower frame is reduced, and the drilling machine tower frame is prevented from overturning.
Preferably, said pressure limiting piers 6 comprise various weight specifications. The weight of the pressure limiting pier is selected according to historical wind power data of the construction site, the maximum tensile force borne by the pressure limiting pier can be calculated by combining the maximum wind power data and wind resistance generated by the sunshade net, and therefore the weight of the pressure limiting pier is selected, and the purpose is to prevent the pressure limiting pier from being blown up due to overlarge wind power.
Meanwhile, the relation between the magnetic force between the first magnetic adsorption piece and the second magnetic adsorption piece and the maximum tensile force which can be borne by the drilling machine tower frame should be considered, the magnetic force should be smaller than the maximum tensile force which can be borne by the drilling machine tower frame, and the situation that the drilling machine tower frame topples and the first magnetic adsorption piece and the second magnetic adsorption piece are not separated is prevented.
Furthermore, the maximum friction force between the pressure limiting pier 6 and the ground is smaller than the magnetic force between the first magnetic adsorption piece 7 and the second magnetic adsorption piece 8, and the magnetic force between the first magnetic adsorption piece 7 and the second magnetic adsorption piece 8 is smaller than the gravity of the pressure limiting pier 6. In the embodiment, the pressure limiting pier 6 is freely placed on the ground, and when the maximum friction force between the pressure limiting pier 6 and the ground is smaller than the component force of the external force (which means the pulling force of the automatic disconnection device acting on the pressure limiting pier and comes from the wind resistance generated by the sunshade net) borne by the pressure limiting pier 6 in the direction of the friction force, the pressure limiting pier 6 generates sliding displacement, so that the load on the tower of the drilling machine is reduced; when the wind resistance of the sunshade net acting on the automatic disconnection device is further increased and exceeds the magnetic force between the first magnetic adsorption piece and the second magnetic adsorption piece, the first magnetic adsorption piece and the second magnetic adsorption piece are disconnected, so that the wind resistance generated by the sunshade net (namely the load generated by the sunshade net) is greatly reduced, and the tower of the drilling machine is prevented from overturning.
Example 2:
the embodiment is different from embodiment 1 in that: the magnetic force between the first magnetic adsorption piece 7 and the second magnetic adsorption piece 8 is smaller than the maximum friction force between the pressure limiting pier 6 and the ground. So set up, the pressure limiting mound can not produce the slip displacement, and when the pulling force that receives on automatic disconnection connecting device was greater than the magnetic force between magnetic adsorption piece one 7 and the magnetic adsorption piece two 8, magnetic adsorption piece one 7 and magnetic adsorption piece two 8 then automatic disconnection to the wind resistance that the sunshade net produced is reduced fast, prevents that the phenomenon from toppling to appear in the rig pylon.
In the embodiment, the pressure limiting pier can select an object with larger weight, and simultaneously can select an object with immovable construction site, such as a pile foundation and the like; if some immovable pile foundations are directly selected, the step of calculating the weight of the pressure limiting pier can be omitted.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
