The invention discloses an anti-overturning method for lifting and dropping an auxiliary plate for
long-section, single-row and two-lining operation of a frozen deep shaft, which comprises the
following steps: steel wire ropes and protection ropes are installed on a hanging scaffold; the
steel wire rope is sleeved by a steel pipe, an auxiliary plate is installed at the lower end of the
steel wire rope, and a plurality of channel steels are uniformly welded at the bottom of the
auxiliary plate along the outer side. The unit is simple in structure and convenient to use, and can

[0001] 1. Technical Field
[0002] The present invention belongs to a building construction method, in particular to an anti overturning method for lifting and dropping an auxiliary plate for long-section, single-row and two-lining operation of a frozen deep shaft.
[0003] 2. Description of Related Art
[0004] When the outer wall of the frozen deep shaft is constructed to the bottom by short section excavation (section height is generally 3.0-6.0m), the whole frozen section (such as 950m) will be lined with 1.0-1.5m high combined steel formwork from bottom to top. Therefore, it is necessary to reform the two-layer or three-layer hanging plate (remove the big claw and bell mouth suspended by the lower plate, and cover them with openable wooden boards), and add an auxiliary plate to the lower part for formwork removal, cleaning and oil brushing. However, when the auxiliary plate is hung with steel wire rope, the auxiliary plate is easy to be collided to overturn during lifting and dropping, resulting in accidents of personnel and formwork on the plate falling into the shaft. At present, there is no unit for effectively preventing the auxiliary plate from overturning due to collision.
[0005] The purpose of the present invention is to provide an anti-overturning method for lifting and dropping an auxiliary plate for long-section, single-row and two-lining operation of a frozen deep shaft. The method can effectively prevent personnel on the plate and formwork from falling into the shaft due to overturning caused by collision of the auxiliary plate during the construction of the second lining of the frozen deep shaft.
[0006] The technical solution of the present invention is as follows: anti-overturning method for lifting and dropping an auxiliary plate for long-section, single-row and two-lining operation of a frozen deep shaft, wherein four first lifting points are arranged on the hanging plate, and steel wire ropes for suspending the auxiliary plate are respectively installed at the four lifting points; an auxiliary plate is installed at the lower end of the steel wire rope, and a plurality of channel steels are uniformly welded at the bottom of the auxiliary plate along the outer side.
[0007] On the basis of the above solution, the outer side of the steel wire rope is sleeved with a steel pipe.
[0008] On the basis of the above solution, the four first hanging points are uniformly arranged on the hanging plate, and the distances between the four hanging points and the center of the circle of the hanging plate are equal.
[0009] On the basis of the above solution, the number of channel steels welded at the bottom of the auxiliary plate is 12.
[0010] On the basis of the above solution, the hanging plate is also provided with two second hanging points, and the connecting line between the two second hanging points passes through the center of circle of the hanging plate; the second lifting point is provided with a protection rope.
[0011] The present invention has the following advantages and positive effects:
[0012] 1. In order to ensure the stability and safety of the auxiliary plate, the four steel wire ropes for suspending the auxiliary plate of the present invention are sleeved with 2-inch steel pipes to prevent the soft ropes from loosening so as to find collision to occur on the auxiliary plate as early as possible. The signalman immediately transmits a signal to stop the lifting of the hanging plate to the shaft, and the underground personnel quickly arrange to eliminate potential safety hazards.
[0013] 2. According to the invention, two steel wire ropes are also installed on the hanging plate as protection ropes, and safety belts, wire rope net, tools, etc. are installed to effectively prevent personnel and objects from falling.
[0014] 3. In the present invention, 12 pieces of 164 channel steels are uniformly welded along the outer side of the bottom of the auxiliary plate. When the auxiliary plate is collided to incline in any direction around, the bottom end of the channel steels is tilted against the formwork or the shaft lining to prevent the auxiliary plate from continuing to tilt, thereby avoiding accidents of personnel on the plate and the formwork falling into the shaft.
[0015] In order to explain the embodiments of the present invention or the technical solutions in the prior art more clearly, the accompanying drawings required in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention, and a person of ordinary skill in the art can still derive other drawings according to these accompanying drawings without creative efforts.
[0016] Fig. 1 is a structure diagram of the present invention;
[0017] Fig. 2 is a schematic diagram of the wire rope hanging point of the auxiliary plate;
[0018] Fig. 3 is a schematic diagram of 12 pieces of 16# channel steels welded to the auxiliary plate;
[0019] Fig. 4 is a principal diagram of the present invention.
[0020] In the figure: 1. shaft hanging plate; 2. steel wire rope; 3. protection rope; 4. steel pipe; 5. auxiliary plate; 6. channel steel; 7. first hanging point; 8. second hanging point; 9. formwork or shaft lining.
[0021] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.
[0022] As shown in the figure:
[0023] An anti-overturning method for lifting and dropping an auxiliary plate for long-section, single-row and two-lining operation of a frozen deep shaft, wherein four first lifting points 7 are arranged on the hanging plate 1, and steel wire ropes 2 for suspending the auxiliary plate 5 are respectively installed at the four lifting points 7; an auxiliary plate 5 is installed at the lower end of the steel wire rope, and a plurality of channel steels 6 are uniformly welded along the outer side at the bottom of the auxiliary plate 5, and the channel steels 6 are 164 channel steels with a length of 1.4m. When the auxiliary plate 5 is collided to incline in any direction around, the bottom ends of 12 pieces of 16# channel steels 6 are tilted against the formwork or the shaft lining 9 to prevent the auxiliary plate from continuing to tilt and avoid accidents of personnel on the plate and formwork falling into the shaft.
[0024] As a specific solution, a steel pipe 4 is sleeved on the outside of the steel wire rope 2. The steel pipe 4 is configured to facilitate to find looseness of the steel wire rope 2 in time.
[0025] As a specific solution, the four first lifting points are evenly arranged on the hanging plate, and the distances between the four lifting points and the center of the circle of the hanging plate are equal. The arrangement can keep the auxiliary plate 5 and the hanging plate 1 in effective balance.
[0026] As a specific solution, the number of channel steels 6 welded to the bottom of the auxiliary plate 5 is 12.
[0027] As a specific solution, the hanging plate 1 is also provided with two second hanging points 8, and the connecting line between the two second hanging points 8 passes through the center of the circle of the hanging plate 1; the second lifting point 8 is provided with a protection rope. The protection rope 3 can be hung with safety belts, wire rope net, tools, etc.
[0028] It should be understood that although the present description is described in terms of the implementation, not every implementation includes only one separate technical solution, and such a description mode of the description is merely for the sake of clarity. A person skilled in the art should take the description as a whole, and the technical solutions in all the embodiments may be appropriately combined to form other implementations that can be understood by a person skilled in the art.
