Description
Technical Field
The invention relates to a manned platform suitable for installation of a fan foundation anchor bolt assembly, and belongs to the technical field of fan foundation installation.
Background
For the anchor bolt assembly constituting one of the foundations of a wind turbine (abbreviated as a wind turbine), it is necessary to install a plurality of anchor bolts on the upper anchor plate and the lower anchor plate which are vertically spaced apart, as shown in fig. 1. During installation, the lower anchor plate is provided with the positioning anchor bolts, the upper anchor plate is hoisted to a certain height by the crane and slowly moved to the position right above the lower anchor plate, and the temporary steel nuts are screwed in the anchor bolt holes which are symmetrically penetrated into the upper anchor plate by the installer standing on the upper anchor plate and uniformly distributed at the upper ends of the positioning anchor bolts. And after the installation and adjustment of the positioning anchor bolts are finished, all the common anchor bolts are penetrated. When the installation, the installer who stands at last anchor plate is in high altitude construction, has the problem of potential safety hazard, and the concrete expression is in:
1. during hoisting, constructors sit on the anchor plate, and the regulation that 'no person is on the hoisted object' of the safety regulation is violated;
2. in the whole construction operation process, constructors can only sit on the upper anchor plate, the inner part of the upper anchor plate is completely hollow, the inner part of the upper anchor plate is hollow, the distance between a safety belt hanging point and a lifting hook plumb line is more than 2m, and secondary damage caused by falling and swinging collision is easy to occur;
3. a constructor sits on the upper anchor plate to position a plurality of one hundred anchor bolts one by one, and the levelness of the upper anchor plate is adjusted, the concentricity of the upper anchor plate and the lower anchor plate is adjusted, the exposure length value of the anchor bolts is adjusted, the upper anchor plate and the lower anchor plate are exposed to the high altitude for a long time, and the safety risk is extremely high;
4. the installation area of the anchor bolt assembly is concentrated with intensive personnel and needs to work simultaneously, and the cross operation of the two ends of the anchor bolt in the vertical space of the upper anchor plate and the lower anchor plate easily causes the safety accidents of people injury by falling objects, high falling, mechanical striking and the like.
At chinese patent publication CN 209277509U's portable scaffold frame for installation of fan prestressed anchor bolt, the staff can install the crab-bolt on the scaffold frame that lies in anchor bolt board one side, the above-mentioned problem that has the potential safety hazard is solved, however, in the crab-bolt installation, in order to prevent the toppling that whole focus skew caused, must install simultaneously at a word or cross diagonal position, there is the problem that needs frequent removal scaffold frame, and in later stage survey crew measures and adjusts the concentricity of anchor slab and lower anchor slab, the levelness of upper anchor slab, when anchor slab length value is exposed to the crab-bolt upper end, also there is the problem that needs frequent removal scaffold frame.

Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
See the structure shown in fig. 1-5.
The invention relates to a manned platform suitable for installing a fan foundation anchor bolt assembly, which comprises:
a platform means 1 located centrally within the internal diameter of the upper anchor plate 42 in use;
the bracket mechanisms 2 are detachably fixed with the anchor bolt holes of the upper anchor plate 42 through screws or bolts during installation, and the plurality of bracket mechanisms 2 are uniformly distributed and fixed on the platform mechanism 1 at intervals;
through the rigidity safety barrier mechanism 3 of screw or bolt demountable installation on platform mechanism 1, rigidity safety barrier mechanism 3 protects the operating personnel who lies in on platform mechanism 1.
After the anchor bolts 41 for positioning are installed on the lower anchor plate 43, the manned platform is installed with the upper anchor plate 42 through the bracket mechanism 2, the manned platform and the upper anchor plate 42 are lifted by the crane to be right above the lower anchor plate 43, the upper anchor plate 42 and the anchor bolts 41 for positioning are installed, when the rest of the anchor bolts 41 are installed, an operator installs the anchor bolts 43 on the platform mechanism 1 at the same time in a straight line or a cross diagonal position from any surface of the upper anchor plate 42 under the protection of the rigid safety guardrail mechanism 3, the problem that the scaffold needs to be frequently moved when the scaffold is used is solved, and the scaffold does not need to be frequently moved when a later-stage measuring person can measure and adjust the concentricity of the upper anchor plate and the lower anchor plate, the levelness of the upper anchor plate and the length value of the upper anchor plate exposed at the upper end of the anchor bolts on the platform mechanism 1.
The lifting lug 5 is screwed with the anchor bolt hole of the upper anchor plate 42 during use, the lifting lugs 5 are screwed in the anchor bolt holes of the upper anchor plate 42 at uniform intervals, and the manned platform and the upper anchor plate 42 are conveniently lifted to be right above the lower anchor plate 43 through the lifting lugs 5 by a crane through a binding band.
The platform mechanism 1 comprises a table top 11 which is formed by welding steel plates and/or steel beams into a whole or forming a detachable whole through bolts;
the table top 11 is provided with a manual through hole, and an operator can conveniently and temporarily mount and build a stair to go up and down through the manual through hole;
a cover plate 12 is rotatably arranged on the table top 11 positioned at the side of the artificial through hole through hinge, and the artificial through hole can be covered by the cover plate 12 for safety;
the periphery of the table top 11 is fixedly connected with a platform foot baffle plate 13 through screws or welding, and because during installation, the periphery of the table top 11 is separated from the bottom of the upper anchor plate, the installation platform foot baffle plate 13 can protect the feet of workers.
The platform mechanism 1 is installed in the inner diameter space of the upper anchor plate 42, so that a person operating the anchor bolt 41 can obtain a standing foundation, and although the problem of potential safety hazard is solved, the operation requirements of measuring and adjusting the concentricity of the upper anchor plate and the lower anchor plate, the levelness of the upper anchor plate and the length value of the upper anchor plate exposed at the upper end of the anchor bolt at the later stage are considered in the installation of the platform mechanism 1.
In order to support the platform mechanism 1 in the space of the inner diameter of the upper anchor plate 42 and to support the platform mechanism 1 directly from the ground at the bottom of the inner diameter of the upper anchor plate 42, for example, in an anchor type pile foundation of chinese patent publication No. CN207130726U, an anchor member is rammed into the ground from the middle of the inner diameter of the upper anchor plate, although the anchor member can support the platform mechanism 1 in the space of the inner diameter of the upper anchor plate 42, when the platform mechanism 1 is lifted up for measurement, the anchor member located in the space below the inner diameter of the upper anchor plate 42 is shaken in a large arc, the bottom of the anchor member easily collides with the lower anchor plate 43 or the lower part of the anchor bolt 41, and there is a problem that the lower anchor plate 43 or the anchor bolt 41 is damaged by the anchor member located in the space below the inner diameter of the upper anchor plate 42.
