And it is ensured that the deviation between the actual dumping direction and the target dumping direction of the steel vertical barrel equipment is very small, and the problem that according to an existing directional window dumping dismantling method, the perpendicularity is changed in the cutting process before dumping, and consequently the final actual dumping direction and the target dumping direction have large deviation is solved.

Description

Technical Field

[0001] The invention relates to a directional dumping and dismantling method, in particular to a directional dumping and dismantling method for steel vertical cylinder equipment. Background Art

[0002] At present, the dismantling of steel vertical equipment in the demolition market is rapidly developing from the conventional segmented cutting and hoisting dismantling method to the directional dumping method. Whether the vertical equipment can be accurately dumped as expected is the key to the directional dumping technology. In the existing technology, the conventional segmented cutting and hoisting dismantling method is used for dismantling steel vertical equipment, which has the problems of high safety risks, slow speed and high cost. If only the directional window dumping technology is used for dismantling, there are problems of large deviation in the dumping direction and high safety risks. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for directional dumping and dismantling of steel vertical cylinder equipment, so as to solve the problems of large dumping direction deviation and high safety risk in the prior art.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0005] A method for directional dumping and dismantling of steel vertical cylinder equipment, characterized in that: it is applicable to the dismantling construction of steel vertical cylinder equipment such as towers, vertical containers (such as blast furnaces, large storage tanks), etc.;

[0006] include:

[0007] Step S1, select the target dumping direction of the steel vertical cylinder equipment, and mark the positions of the directional window, the first support line, the second support line and the third support line on the cylinder wall of the steel vertical cylinder equipment, and meet the following conditions:

[0008] Condition 1: The target dumping direction is that the central axis of the steel vertical cylinder equipment points to the direction of the center line of the orientation window, and the coplanarity of the central axis and the center line is recorded as vertical coplanarity;

[0009] Condition 2: The bottom edge of the directional window, the first support line, the first foot line, the third support line, the second foot line and the second support line are located in the same horizontal plane and are connected end to end on the wall of the steel vertical cylinder equipment to form a closed line;

[0010] Condition 3: The length of the bottom side of the directional window is greater than half of the length of the closed line; that is, the first support line, the second support line and the third support line are located on the same half of the cross section of the steel vertical cylinder equipment;

[0011] Condition 4: The lengths of the first support line and the second support line are equal and symmetrical about the vertical coplane;

[0012] Condition 5: The midpoint of the third support line is located within the vertical coplanar plane;

[0013] Step S2, cutting the directional window on the cylinder wall of the steel vertical cylinder equipment;

[0014] Step S3, cutting out the first foot line and the second foot line at the same time;

[0015] During the above process: the cutting equipment and personnel are positioned to the side and rear of the target dumping direction of the steel vertical cylinder equipment to ensure safety.

[0016] Step S4, using an instrument to measure the real-time verticality of the steel vertical cylinder equipment, and after determining that the real-time verticality has no dynamic change, executing step S5;

[0017] In the above process: the first support line, the second support line and the third support line are strictly reserved and cannot be cut; and the lengths of the first support line, the second support line and the third support line and the orientations of the first support line and the second support line are determined comprehensively according to the specifications, wall thickness, weight and on-site wind load of the steel vertical cylinder equipment, so as to ensure that the steel vertical cylinder equipment is stable and does not tip over after completing step S3.

[0018] Step S5, cutting the third support line so that the steel vertical cylinder equipment can be safely dumped in the target dumping direction under the action of its own gravity. The cutting speed of step S5 should be slow to avoid the third support line from breaking suddenly and causing safety risks.

[0019] Among them, the dumping speed of the steel vertical cylinder equipment is affected by the size of the directional window. The size of the directional window cannot be too large, otherwise the dumping speed will be too fast and affect the safety of on-site workers. The size of the directional window cannot be too small, otherwise the steel vertical cylinder equipment may not be completely dumped. Therefore, the size and shape of the directional window should be determined comprehensively based on the specifications, wall thickness, center of gravity position, and dumping speed of the steel vertical cylinder equipment.

[0020] In addition, the invention can select automatic cutting equipment or manual cutting method for cutting. When manual cutting is adopted, it is advisable to use an extended rod cutting gun for high cutting lines.

[0021] Thus, the present invention first cuts out the directional window, the first foot line and the second foot line, and after determining that the real-time verticality of the steel vertical cylinder equipment has no dynamic change, the third support line is cut to make the steel vertical cylinder equipment safely tip over in the target tipping direction under the action of its own gravity; because the directional window, the first support line, the second support line and the third support line meet conditions one to five, before cutting the third support line, the steel vertical cylinder equipment can remain stable without verticality change or only have a very small verticality change under the support of the first support line, the second support line and the third support line, ensuring that the deviation between the actual tipping direction of the steel vertical cylinder equipment and the target tipping direction is very small, avoiding the problem of the existing directional window tipping and removal method causing the change of verticality due to the cutting process before tipping, resulting in a large deviation between the final actual tipping direction and the target tipping direction; therefore, the present invention has the advantages of small tipping deviation and low safety risk.

[0022] As a preferred embodiment of the present invention: the orientation window is an isosceles trapezoidal window with a short top side and a long bottom side; wherein the top side of the orientation window is a line between point c and point d, and point a is the midpoint of the top side; the bottom side of the orientation window is a line between point e and point f, and point b is the midpoint of the bottom side;

[0023] The specific process of step S2 includes:

[0024] Step S2-1, cutting out the center line of the directional window along the direction from point a to point b;

[0025] Step S2-2, performing synchronous cutting along the direction from point a to point c and the direction from point a to point d to cut out the top edge of the directional window;

[0026] Step S2-3, performing synchronous cutting along the direction from point c to point e and the direction from point d to point f to cut out two waist edges of the directional window;

[0027] Step S2-4: Perform synchronous cutting along the direction from point b to point e and the direction from point b to point f to cut out the bottom edge of the directional window.

[0028] Among them, steps S2-2 to S2-4 and step S3 are all performed simultaneously by two people or two devices, and steps S2-1 and S5 can be performed by one person or one device.

[0029] Therefore, in steps S2-2 to S2-4 of the present invention, the directional window is cut in a symmetrical and synchronous manner, so that the force of the steel vertical cylinder equipment is balanced during cutting, and the verticality will not change or only change very little due to the cutting process, further ensuring that the actual tipping direction of the steel vertical cylinder equipment deviates little from the target tipping direction.

[0030] In addition, the orientation window may also be arcuate.

[0031] Preferably: the first support line is the line between point e and point g, the first foot line is the line between point g and point h, the third support line is the line between point h and point j, the second foot line is the line between point j and point i, and the third support line is the line between point i and point f;

[0032] In the step S3, synchronous cutting is performed along the direction from point g to point h and the direction from point i to point j, or synchronous cutting is performed along the direction from point h to point g and the direction from point j to point i, so as to simultaneously cut out the first foot line and the second foot line.

[0033] Therefore, in step S3 of the present invention, the first leg line and the second leg line are cut in a symmetrical and synchronous manner, so that the force of the steel vertical cylinder equipment is balanced during cutting, and the verticality will not change or only change very slightly due to the cutting process, further ensuring that the actual tipping direction of the steel vertical cylinder equipment deviates little from the target tipping direction.

[0034] Preferably: before executing the step S2, the initial verticality of the steel vertical cylinder equipment is measured by an instrument; and after executing step S2, the current verticality of the steel vertical cylinder equipment is measured by an instrument, and the current verticality is compared with the initial verticality. If the comparison result indicates that the steel vertical cylinder equipment has a tendency to tilt toward the target tipping direction, step S3 is executed; otherwise, it indicates that there is a large deviation between the tipping trend of the steel vertical cylinder equipment and the target tipping direction, and there is a large safety risk. The operation should be stopped and the demolition plan should be adjusted according to the situation.

[0035] Therefore, the present invention compares the changes in the current verticality with the initial verticality, and executes step S3 only when it is determined based on the comparison result that the steel vertical cylinder equipment has a tendency to tilt toward the target tipping direction. This can effectively avoid the safety risks caused by a large deviation between the tipping trend of the steel vertical cylinder equipment and the target tipping direction, thereby improving the safety of the present invention.

[0036] Preferably: when the third support line is cut in step S5, the real-time verticality of the steel vertical cylinder equipment is continuously and dynamically monitored, and when a dynamic change in the real-time verticality is detected, it is determined that the steel vertical cylinder equipment begins to tip over, and the cutting personnel and equipment are notified to quickly evacuate in the opposite direction of the tipping of the steel vertical cylinder equipment.

[0037] Before executing step S1, it is confirmed that the floor space where the steel vertical cylinder equipment is located meets the safety operation requirements, and then step S1 is executed.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] First, the present invention first cuts out the directional window 1-2, the first foot line D and the second foot line E, and after determining that the real-time verticality of the steel vertical cylinder equipment 1 has no dynamic change, the third support line C is cut to make the steel vertical cylinder equipment 1 safely tip over in the target tipping direction F under the action of its own gravity; because the directional window 1-2, the first support line A, the second support line B and the third support line C meet conditions one to five, before cutting the third support line C, the steel vertical cylinder equipment 1 can remain stable without verticality change or only have a small verticality change under the support of the first support line A, the second support line B and the third support line C, ensuring that the deviation between the actual tipping direction of the steel vertical cylinder equipment 1 and the target tipping direction F is very small, avoiding the problem that the existing directional window tipping and dismantling method causes the verticality to change due to the cutting process before tipping, resulting in a large deviation between the final actual tipping direction and the target tipping direction; therefore, the present invention has the advantages of small tipping deviation and low safety risk.

[0040] Second, in steps S2-2 to S2-4 of the present invention, the directional window 1-2 is cut in a symmetrical and synchronous manner, so that the force of the steel vertical cylinder equipment 1 is balanced during cutting, and the verticality will not change or only change very slightly due to the cutting process, further ensuring that the actual tipping direction of the steel vertical cylinder equipment 1 has a small deviation from the target tipping direction F.

[0041] Third, in step S3 of the present invention, the first leg line D and the second leg line E are cut in a symmetrical and synchronous manner, so that the force of the steel vertical cylinder equipment 1 is balanced during cutting, and the verticality will not change or only change very slightly due to the cutting process, further ensuring that the actual tipping direction of the steel vertical cylinder equipment 1 has a small deviation from the target tipping direction F.

[0042] Fourthly, the present invention compares the change of the current verticality with the initial verticality, and executes step S3 only when it is judged that the steel vertical cylinder equipment 1 has a tendency to tilt toward the target tipping direction F according to the comparison result. This can effectively avoid the safety risks caused by the large deviation between the tipping trend of the steel vertical cylinder equipment 1 and the target tipping direction F, thereby improving the safety of the present invention.

[0048] Embodiment 1

[0049] like Figures 1 to 3 As shown, the present invention discloses a method for directional dumping and dismantling of a steel vertical cylinder equipment, which is applicable to the dismantling construction of steel vertical cylinder equipment 1 such as towers and vertical containers (such as blast furnaces and large storage tanks);

[0050] include:

[0051] Step S1, select the target dumping direction F of the steel vertical cylinder equipment 1, and mark the positions of the directional window 1-2, the first support line A, the second support line B and the third support line C on the cylinder wall 1-1 of the steel vertical cylinder equipment 1, and meet the following conditions:

[0052] Condition 1: The target dumping direction F is the direction in which the central axis 1-3 of the steel vertical cylinder equipment 1 points to the center line 1-2a of the orientation window 1-2, and the coplanarity of the central axis 1-3 and the center line 1-2a is recorded as the vertical coplanarity 1-4;

[0053] Condition 2: the bottom edge 1-2b of the directional window 1-2, the first support line A, the first foot line D, the third support line C, the second foot line E and the second support line B are located in the same horizontal plane and are connected end to end on the cylinder wall 1-1 of the steel vertical cylinder equipment 1 to form a closed line;

[0054] Condition 3: The length of the bottom edge 1-2b of the directional window 1-2 is greater than half of the length of the closed line; that is, the first support line A, the second support line B and the third support line C are located on the same half of the cross section of the steel vertical cylinder equipment 1;

[0055] Condition 4: The lengths of the first support line A and the second support line B are equal and symmetrical about the vertical coplanar surface 1-4;

[0056] Condition 5: The midpoint C1 of the third support line C is located within the vertical coplanar surface 1-4;

[0057] Step S2, cutting the directional window 1-2 on the cylinder wall 1-1 of the steel vertical cylinder equipment 1;

[0058] Step S3, cutting out the first foot line D and the second foot line E at the same time;

[0059] During the above process, the cutting equipment and personnel are positioned to the rear of the target dumping direction F of the steel vertical cylinder equipment 1 to ensure safety.

[0060] Step S4, using an instrument to measure the real-time verticality of the steel vertical cylinder equipment 1, and after determining that the real-time verticality has no dynamic change, executing step S5;

[0061] In the above process: the first support line A, the second support line B and the third support line C are strictly reserved and cannot be cut; and the lengths of the first support line A, the second support line B and the third support line C and the orientations of the first support line A and the second support line B are determined comprehensively based on the specifications, wall thickness, weight and on-site wind load of the steel vertical cylinder equipment 1, so as to ensure that the steel vertical cylinder equipment 1 is stable and does not tip over after completing step S3.

[0062] Step S5, cutting the third support line C, so that the steel vertical cylinder equipment 1 can be safely dumped in the target dumping direction F under the action of its own gravity. The cutting speed of step S5 should be slow to avoid the third support line C from breaking suddenly and causing safety risks.

[0063] Among them, the dumping speed of the steel vertical cylinder equipment 1 is affected by the size of the directional window 1-2. The size of the directional window 1-2 cannot be too large, otherwise the dumping speed is too fast and will affect the safety of on-site workers. The size of the directional window 1-2 cannot be too small, otherwise the steel vertical cylinder equipment 1 may not be completely dumped. Therefore, the size and shape of the directional window 1-2 should be comprehensively determined based on the specifications, wall thickness, center of gravity position, and dumping speed of the steel vertical cylinder equipment 1.

[0064] In addition, the invention can select automatic cutting equipment or manual cutting method for cutting. When manual cutting is adopted, it is advisable to use an extended rod cutting gun for high cutting lines.

[0065] Therefore, the present invention first cuts out the directional window 1-2, the first foot line D and the second foot line E, and after determining that the real-time verticality of the steel vertical cylinder equipment 1 has no dynamic change, the third support line C is cut to make the steel vertical cylinder equipment 1 safely tip over in the target tipping direction F under the action of its own gravity; because the directional window 1-2, the first support line A, the second support line B and the third support line C meet conditions one to five, before cutting the third support line C, the steel vertical cylinder equipment 1 can remain stable without verticality change or only have a very small verticality change under the support of the first support line A, the second support line B and the third support line C, ensuring that the deviation between the actual tipping direction of the steel vertical cylinder equipment 1 and the target tipping direction F is very small, avoiding the problem that the existing directional window tipping and dismantling method causes the verticality to change due to the cutting process before tipping, resulting in a large deviation between the final actual tipping direction and the target tipping direction; therefore, the present invention has the advantages of small tipping deviation and low safety risk.

[0066] The above is a basic implementation of the first embodiment of the present invention, and further optimization, improvement and limitation can be made on the basis of the basic implementation:

[0067] Preferably: before executing the step S2, the initial verticality of the steel vertical cylinder equipment 1 is measured by an instrument; and after executing step S2, the current verticality of the steel vertical cylinder equipment 1 is measured by an instrument, and the current verticality is compared with the initial verticality. If the comparison result indicates that the steel vertical cylinder equipment 1 has a tendency to tilt toward the target tipping direction F, step S3 is executed; otherwise, it indicates that there is a large deviation between the tipping trend of the steel vertical cylinder equipment 1 and the target tipping direction F, and there is a large safety risk. The operation should be stopped and the demolition plan should be adjusted according to the situation.

[0068] Therefore, the present invention compares the changes in the current verticality with the initial verticality, and executes step S3 only when it is determined according to the comparison result that the steel vertical cylinder equipment 1 has a tendency to tilt toward the target tipping direction F. This can effectively avoid the safety risks caused by the large deviation between the tipping trend of the steel vertical cylinder equipment 1 and the target tipping direction F, thereby improving the safety of the present invention.

[0069] Preferably: when the third support line C is cut in step S5, the real-time verticality of the steel vertical cylinder equipment 1 is continuously and dynamically monitored, and when a dynamic change in the real-time verticality is detected, it is determined that the steel vertical cylinder equipment 1 begins to tip over, and the cutting personnel and equipment are notified to quickly evacuate in the opposite direction of the tipping of the steel vertical cylinder equipment 1.

[0084] In the step S3, synchronous cutting is performed along the direction from point g to point h and the direction from point i to point j, or synchronous cutting is performed along the direction from point h to point g and the direction from point j to point i, so as to simultaneously cut out the first foot line D and the second foot line E.

[0085] Therefore, in step S3 of the present invention, the first leg line D and the second leg line E are cut in a symmetrical and synchronous manner, so that the force of the steel vertical cylinder equipment 1 is balanced during cutting, and the verticality will not change or only change very slightly due to the cutting process, further ensuring that the actual tipping direction of the steel vertical cylinder equipment 1 has a small deviation from the target tipping direction F.

[0086] The present invention is not limited to the above-mentioned specific implementation modes. According to the above-mentioned contents, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the present invention, the present invention can also make other various forms of equivalent modifications, replacements or changes, all of which fall within the protection scope of the present invention.
