Description
Technical Field
The invention relates to the technical field of mines, in particular to a derrick support column. The invention also relates to a derrick comprising the derrick support column and a derrick deviation correcting method.
Background
The derrick is an important lifting structure in mine production, uneven settlement of a derrick foundation can lead to integral inclination of the derrick, huge secondary stress of structural rods and deformation of a cage guide, and has great safety threat to production, and when the derrick is seriously inclined, the derrick can lead to production stoppage of a mine, so that huge economic loss is caused.
For a box-shaped single-side inclined support type derrick (also called as a scull type derrick), as shown in fig. 1, the box-shaped single-side inclined support type derrick mainly comprises an inclined support 02 and a vertical frame 01, wherein the inclined support 02 and the vertical frame 01 form a loaded structure in a hinging manner, a foundation of the vertical frame 01 is located on a shaft 04 of a concrete structure in a rigid connection mode, the shaft 04 is directly connected with bedrock, and the settlement amount is negligible; the diagonal bracing 02 is generally seated on the surface soil foundation by adopting an enlarged diagonal bracing foundation 03. Due to the discreteness of the vertical frame foundation and the inclined support foundation 03, the consolidation and compression of foundation soil, the water level of groundwater is reduced, the lifting load of a derrick is increased, shaft equipment and the derrick are partially transformed, the overall strength of the derrick is reduced, and the like, the inclined support foundation 03 is unevenly settled, and the inclined support foundation 03 is obliquely inclined.
The existing connection mode of the diagonal brace 02 and the diagonal brace foundation 03 mainly adopts pre-buried anchor bolts 05 for fastening connection, as shown in fig. 2, the anchor bolts 05 are pre-buried in the diagonal brace foundation 03, and the base of the diagonal brace 02 is fastened with the anchor bolts 05 in the diagonal brace foundation 03 through nuts. When the derrick is inclined, the derrick needs to be corrected, and the existing correction mode is as follows: the method uses engineering machinery to straighten the main well derrick or uses a jack to forcedly jack up and lift the diagonal bracing, and members such as gaskets are arranged between the base of the diagonal bracing 02 and the diagonal bracing foundation 03 to lengthen and lift the diagonal bracing, thereby achieving the purpose of correcting the derrick. However, the method needs to break the secondary irrigation layer of the diagonal bracing foundation 03, cut the foundation bolts 05, temporarily manufacture the jack base when using the jack to lift the derrick, and also needs to weld the jack base with the jack force on the diagonal bracing 02, and ensure that the top plane of the jack piston contacts with the bottom plane of the unilateral diagonal bracing, the precision is difficult to maintain in the lifting process, and the column feet need to be anchored again after correction. It can be seen that the correction method is complex in process and construction.
In summary, how to solve the problems of complicated correction process and complex construction of the derrick becomes a problem to be solved urgently by those skilled in the art.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 3-15, a derrick support column includes a support column foundation 1, a support column foot 4, and an anchor bolt assembly; the side surface of the top of the support column foundation 1 is reserved with a mounting groove 11 for placing a jacking mechanism; the bottom surface of the support column foot 4 is attached to the top surface of the support column foundation 1, the lower part of the support column foot 4 is covered above the mounting groove 11 and is used for contacting with the top end of the jacking mechanism, and the support column foot 4 is provided with a column foot fixing hole 431; the anchor bolt assembly is provided in the support column foundation 1, and the top end of the anchor bolt assembly passes through the column foot fixing hole 431 and is detachably connected by the nut 32.
When the derrick support column rectifies, as the installation groove position 11 is reserved in the support column foundation 1, the jacking mechanism can be directly placed in the installation groove position 11, before jacking, the nut 32 of the anchor bolt assembly is unscrewed, when jacking, the jacking mechanism directly jacks the lower part of the support column foot 4 in the installation groove position 11, after jacking is completed, the space between the support column foundation 1 and the support column foot 4 is filled up, finally the nut 32 is screwed down for fixing, and the jacking mechanism is taken out from the installation groove position 11, so that the rectification operation is completed.
Compared with the prior art, the foundation bolt 05 does not need to be cut, the jack base does not need to be temporarily manufactured on the diagonal bracing foundation 03, the jack base with the jack force does not need to be welded on the diagonal bracing 02, the column foot does not need to be anchored again by using a new foundation bolt 05 after correction, the correction operation is simplified, the construction is more convenient, and correction can be performed quickly and conveniently. And because the bottom surface of support column foot 4 in this application is laminated with the top surface of support column basis 1, climbing mechanism directly jack-up support column foot 4 cover in the lower part of mounting groove 11, and the precision is kept easily in the jacking process.
Further, in the present embodiment, the plurality of mounting slots 11 are symmetrically arranged on the top side of the support column base 1, and each mounting slot 11 is used for accommodating one lifting mechanism. As shown in fig. 3 to 6, the mounting slots 11 are preferably two and symmetrically arranged at both sides of the top of the support column foundation 1. Of course, the number of the installation slots 11 may be four, six, or more, and the number is not limited to the number listed in the present embodiment.
As shown in fig. 3 to 6, in the present embodiment, the number of anchor bolt assemblies is plural, specifically, two, three, four, five or more, and the anchor bolt assemblies are uniformly disposed in the support column base 1, improving the stability of anchoring.
In order to further improve the jacking precision of the jacking mechanism and facilitate jacking control, in this embodiment, the top surface of the support column foundation 1 is perpendicular to the axis of the support column foot 4, the jacking direction of the jacking mechanism is parallel to the axis of the support column foot 4, and correspondingly, the axis of the mounting groove 11 is perpendicular to the top surface of the support column foundation 1. Therefore, when correcting the deviation, the jacking mechanism jacks up along the axis of the support column foot 4, so that the jacking height of the jacking mechanism is the length of the support column foot 4 moving along the axis, and the correction data of the derrick can be calculated more easily. Of course, the top surface of the support column foundation 1 may not be perpendicular to the axis of the support column foot 4, but the jacking data of the jacking mechanism is not as easy to calculate as in the vertically arranged form.
As shown in fig. 12-15, the present embodiment provides a specific anchor bolt assembly that includes a sleeve unit 2 and an anchor bolt unit 3; wherein, the sleeve unit 2 is pre-buried and poured in the support column foundation 1, and the bottom of the sleeve unit 2 is provided with a limit anchoring hole 221; the anchor bolt unit 3 comprises an anchor bolt 31, a limiting end 34 and a nut 32, wherein the limiting end 34 is arranged at the bottom end of the anchor bolt 31, the anchor bolt 31 is used for being inserted into the sleeve unit 2, the limiting end 34 is used for penetrating through a limiting anchoring hole 221, the limiting end 34 is axially positioned and anchored with the limiting anchoring hole 221 after rotating through the anchor bolt 31, and the top end of the anchor bolt 31 penetrates through a column base fixing hole 431; the nut 32 is screwed to the top of the anchor bolt 31.
The working principle of the anchor bolt assembly is as follows: the anchor bolt unit 3 and the sleeve unit 2 are arranged in a split mode, the sleeve unit 2 is embedded and poured into the support column foundation 1, the anchor bolt unit 3 and the support column foundation 1 are not fixed in a pouring mode, and the anchor bolt unit can be installed in the support column foundation 1 subsequently and can be detached from the support column foundation 1 for replacement. When the support column foot 4 is connected with the support column foundation 1, firstly, the bottom surface of the support column foot 4 is attached to the top surface of the support column foundation 1, the column foot fixing hole 431 of the support column foot 4 is aligned with the top opening of the sleeve unit 2, the limit end 34 of the anchor bolt 31 downwards passes through the column foot fixing hole 431 from top to bottom, the anchor bolt 31 is inserted into the sleeve unit 2, the position of the anchor bolt 31 is adjusted, the limit end 34 can pass through the limit anchoring hole 221, then, the anchor bolt 31 is rotated for a certain angle, the limit end 34 is staggered with the limit anchoring hole 221, so that the axial positioning anchoring of the limit end 34 and the limit anchoring hole 221 is realized, and finally, the support column foot 4 and the support column foundation 1 are anchored by screwing the top end of the anchor bolt 31 through the column foot fixing hole 431 through the nut 32.
When deviation correction is performed, if the jacking height exceeds the length of the anchor bolt 31, the anchor bolt 31 can be rotated, after the limiting end 34 is aligned with the limiting anchoring hole 221, the anchor bolt unit 3 is taken out upwards, and the anchor bolt unit 3 with a longer length can be replaced. Compared with the prior art in which the anchor bolts 05 are directly embedded, the anchor bolt assembly can be used for replacing the anchor bolt unit 3 so as to overcome the defect that the length of the anchor bolts 05 is insufficient after the derrick is lifted, and can well solve the aging problem of the anchor bolts 05 caused by the effects of perennial abrasion, dampness and corrosion.
Further, as shown in fig. 12, in order to enhance the fastening firmness of the nut 32 and the anchor bolt 31, in the present embodiment, the anchor bolt unit 3 further includes a pad 33 that is sleeved on the top end of the anchor bolt 31 and is located between the nut 32 and the column base fixing hole 431, and the size of the pad 33 is larger than that of the column base fixing hole 431.
Further, in the present embodiment, the sleeve unit 2 includes, from top to bottom, an upper sleeve 21, an upper baffle 22, a lower sleeve 23, and a lower baffle 24, wherein the upper sleeve 21 is used for passing through the anchor bolt unit 3, the upper baffle 22 is fixed at the bottom end of the upper sleeve 21, and a limit anchoring hole 221 is formed in the upper baffle 22; the upper baffle 22 covers the top end of the lower sleeve 23, the lower baffle 24 is fixed to the bottom end of the lower sleeve 23, and the lower sleeve 23 is used for accommodating the limiting end 34. The anchor bolt 31 passes through the upper sleeve 21, the limiting end 34 passes through the limiting anchoring hole 221 of the upper baffle plate 22 and then enters the lower sleeve 23, the limiting end 34 rotates in the lower sleeve 23, after rotating by a specific angle, the limiting end 34 is staggered with the limiting anchoring hole 221, and the limiting end 34 is axially limited by the upper baffle plate 21.
The sleeve unit 2 is welded by adopting a steel structure, is convenient to process and manufacture, has low cost, and can be of an integrally formed structure.
As shown in fig. 13 to 14, in this embodiment, the stopper end 34 is a rectangular plate perpendicular to the axis of the anchor bolt 31, and the stopper anchor hole 221 is a rectangular hole conforming to the outer shape of the rectangular plate. The limit ends 34 form a T-shaped structure with the anchor bolts 31, and each side of the rectangular plate is preferably 2-4 cm smaller than the rectangular hole so that the rectangular plate passes through the rectangular hole. After the rectangular plate passes through the rectangular hole, the rectangular plate rotates for a certain angle, the rectangular plate is staggered with the rectangular hole, so that axial limiting anchoring can be realized, and the anchoring firmness is better when the rotation angle of the anchor bolt 31 is 90 degrees generally, and of course, any angle between 10 degrees and 90 degrees can be realized.
Further, in the present embodiment, the upper sleeve 21 is a rectangular sleeve, and the lower sleeve 23 is a circular sleeve.
