Wherein, the spacing support member 100 is arranged on the pillar 500, one end of the support adjusting member 200 is hinged on the ground 600, the other end is hinged on the spacing support member 100 to support the pillar 500, and the distance between the two ends of the support adjusting member 200 can be changed to adjust the included angle between the pillar 500 and the horizontal plane.

In this embodiment, the limiting support member 100 is used to cooperate with the support adjusting member 200 to limit and support the pillar 500, so as to avoid the pillar 500 from falling down due to an excessive slope to further cause a safety accident. When the adjustable supporting device is used, the included angle between the supporting column 500 and the horizontal plane can be adjusted and changed by adjusting and changing the distance between the two ends of the supporting and adjusting component 200, so that the slope of the supporting column 500 is reduced, and the aim of correcting the supporting column is fulfilled.

The pillar straightening device is uncomplicated in composition, simple in structure and convenient to assemble, the straightening of the pillar 500 can be realized by the mutual matching of the supporting and adjusting part 200 and the limiting and supporting part 100, the operation and the use are simple, the number of actual operators can be reduced by 50%, and the labor cost is reduced; can realize just fast through simple operation, promote work efficiency, can just be roughly 30 pillars through the actual measurement every day, total efficiency of construction has improved 100%, also can reduce the amount of labour.

Because the whole weight of the pillar correcting device can be reduced to a great extent, and all the parts forming the pillar correcting device can be designed into a detachable form according to needs, the device is convenient to carry about manually and transport between adjacent pillars rapidly, and the transportation cost is saved.

In some embodiments, the support adjustment members 200 are distributed circumferentially around the stanchion 500 for supporting the stanchion 500 from multiple directions and adjusting the angle between the stanchion 500 and the horizontal plane. The supporting and adjusting components 200 distributed and arranged around the circumference of the supporting column 500 can overcome the problem that the angle of the supporting column 500 cannot be adjusted easily from a single side, and the supporting and adjusting components can be matched and adjusted from multiple directions to adapt to the condition that the supporting column 500 inclines to various directions. It will be appreciated that in other embodiments, the support adjustment member 200 may be provided on one side of the support pole to support the support pole 500 from only one direction and adjust the angle between the support pole 500 and the horizontal, which may accommodate the tilt of the support pole 500 to a single orientation.

Referring to fig. 1, in some embodiments, the support adjustment member 200 includes a telescoping rod 210. The distance between the two ends of the telescopic rod 210 can be changed by adjusting the length of the whole telescopic rod, so that the included angle between the supporting column 500 and the horizontal plane can be freely adjusted, and the operation is easy and convenient.

Preferably, the plurality of telescopic rods 210 are distributed around the circumference of the supporting column 500, and the central axis of the telescopic rod 210 intersects with the central axis of the supporting column 500. The telescopic rods 210 can be matched with and adjust the included angles between the support 500 and the horizontal plane from multiple directions, and the intersection of the central axes of the telescopic rods 210 and the central line of the support 500 can ensure that the thrust applied to the support 500 when the telescopic rods 210 extend out can pass through the center of the support 500, so that the support 500 is prevented from being deviated sideways under the action of lateral force; meanwhile, the intersection of the central axis of the telescopic rod 210 and the central axis of the supporting column 500 can ensure that the maximum pushing force is applied to the supporting column 500 when the telescopic rod 210 extends out, so that the adjusting speed is ensured.

Under some working conditions, the slope of the adjusted strut 500 is required to be about a thousandth, the jacking speed and the retracting speed in the straightening process are required not to be too high, and the jacking speed is preferably 4-8 mm. Therefore, referring to fig. 1, in some embodiments, the telescopic rod 210 includes an electric push rod, the electric push rod can achieve stepless adjustment of the length of the telescopic rod 210, the adjustment speed is stable, accurate control over the adjustment precision can be achieved, repeated adjustment of the same strut 500 due to uncontrollable adjustment speed is avoided, and the adjustment efficiency is improved. The electric push rod is a common electric driving device which converts the rotary motion of the motor into the linear reciprocating motion of the push rod, when in specific use, the motor of the electric push rod can be electrically connected with an external controller 220, and the whole extension and the shortening of the electric push rod can be controlled by operating a switch on the controller 220; the power source of the electric push rod can be a storage battery 230, the storage battery 230 is electrically connected with the controller 220, the controller 220 and the electric push rod can be powered simultaneously, and the storage battery 230 is adopted as the power source, so that the electric push rod is convenient to carry, safe and reliable.

Considering the convenience of installation, disassembly and use and the convenience of transferring among different struts 500, the whole length of the electric push rod is shortened to the shortest length, and the length is not more than 900 mm; meanwhile, considering the height of the supporting column 500 and the angle of the force, the length of the electric push rod is not smaller than 1300mm when the electric push rod extends to the limit.

The manual adjustment mode is troublesome and labor-consuming in operation, the adjustment efficiency is not high, and the adjustment precision cannot reach higher standards easily.

In addition to using the telescopic rod 210, in other embodiments, it can be understood that the support adjusting member 200 may further include a connecting rod assembly, the connecting rod assembly is formed by connecting multiple segments of rod members in sequence, and the purpose of adjusting the length of the whole connecting rod assembly can be achieved by changing the included angle between any two connected segments of rod members, so as to adjust the included angle between the pillar 500 and the horizontal plane.

Referring to fig. 3, in some embodiments, the spacing support 100 is a support ring circumferentially surrounding the stanchion 500, the support ring comprising two half-rings 110, the corresponding ends of the two half-rings 110 being secured together by bolts 120.

Preferably, support rings of different shapes can be designed corresponding to the pillars 500 of different cross-sections to cooperate with the limited support of the corresponding pillars 500, for example, when the pillars 500 are circular in cross-section, the support rings are circular, and when the pillars 500 are square in cross-section, the support rings are square, which improves the adaptability to various types of pillars 500.

It is understood that in other embodiments, the spacing supporter 100 may be a hinge point fixed on the surface of the supporting column 500, and the supporting-adjusting part 200 is hinged to the hinge point to support the supporting column 500, and the angle between the supporting column and the horizontal plane can be adjusted by changing the distance between the two ends of the supporting-adjusting part 200.

Referring to fig. 4 and 5, in some embodiments, a positioning device is further included, and the support adjusting member 200 is hinged to the ground 600 by the positioning device; the positioning device comprises a positioning plate 300 and a fixing pin 320, the positioning plate 300 is arranged on the ground 600, the connecting ring 310 is arranged on the surface of the positioning plate, and the fixing pin 320 penetrates through the connecting ring 310 and the hinge ring 201 arranged at the end of the support adjusting component 200 so as to hinge the end of the support adjusting component 200 to the positioning plate 300. The end of the supporting and adjusting member 200 is hinged to the positioning plate 300, so that the connection stability between the supporting and adjusting member 200 and the ground 600 can be enhanced, and the safety accident that the supporting of the supporting column 500 is failed or the supporting column 500 is toppled over due to the sliding along the ground 600 can be avoided.

Preferably, the positioning device further comprises a fixing member, and the positioning plate 300 is fixed on the ground 600 through the fixing member; the fixing member includes a plurality of positioning pins 330 circumferentially distributed on the positioning plate 300, and the positioning pins 330 pass through the positioning plate 300 and are screwed into the ground 600. Can firmly fix locating plate 300 on ground 600 through locating pin 330, make things convenient for the quick installation and the dismantlement of locating plate 300 simultaneously.

Referring to fig. 1, in some embodiments, a slope measuring device 400 is further included, disposed on the pillar 500, for measuring the slope of the pillar 500. The smaller the slope, the larger the included angle between the pillar 500 and the horizontal plane is, the more 90 degrees the included angle between the pillar 500 and the horizontal plane reaches when the slope is 0, and the slope measuring device 400 can measure the slope of the pillar 500 in real time, so that the adjusting operation is more convenient and faster, the operation efficiency is further improved, and the labor capacity is reduced.

On a high-speed railway, the requirement of the slope precision of the support column 500 is basically in the order of thousandths (0.001), so that a higher requirement is put on the correction of the support column 500. For this purpose, the slope measuring device 400 preferably comprises two electronic levels 410, the two electronic levels 410 are disposed at two different positions on the circumferential surface of the pillar 500, and both electronic levels 410 are attached to the surface of the pillar 500.

By adopting the setting mode of the embodiment, the final slope value can meet higher requirements, and the final correction precision of the support column 500 can be effectively improved.

Of course, in other embodiments, the slope measuring device 400 may be a traditional line pendant or a bubble ruler, which does not affect the normal implementation of the functions of the present invention, and only the adjustment precision cannot meet the higher requirement of the use environment, and is not limited herein.
