the straightening device is positioned aiming at the bending part of the transverse amplitude rod 11; two clamping components 21 in the clamping mechanism 2 are respectively clamped and fixed on the body of the transverse amplitude rod 11 at two ends of the bent part of the transverse amplitude rod 11, and then are connected with the two clamping components 21 through a supporting rod 4 to form a closed frame formed by enclosing the two clamping components 21, the supporting rod 4 and the bent part of the transverse amplitude rod 11, wherein the two clamping components 21 are two opposite sides in the frame, the supporting rod 4 and the bent part of the transverse amplitude rod 11 are two opposite sides in the frame, a jacking mechanism 3 is erected in the frame, one end of the jacking mechanism 3 abuts against the supporting rod 4, and the other end abuts against the convex surface of the bent part of the transverse amplitude rod 11; and starting the jacking mechanism 3 to enable the jacking mechanism 3 to push the convex part of the bending part of the transverse amplitude rod 11 to deform by taking the supporting rod 4 as a fulcrum, so that the bending part of the transverse amplitude rod 11 is restored to the original shape, and the straightening effect of the transverse amplitude rod 11 is realized. The device can be used after being installed on the transverse amplitude rod 11, so that the step of disassembling/installing the transverse amplitude rod 11 is omitted, and a large amount of working hours are saved; meanwhile, the problem that the quality of a connecting point is difficult to guarantee due to the fact that the transverse amplitude rod 11 is installed again is avoided, and the safety of tower crane construction is improved.
Based on the scheme, the transverse amplitude rod 11 on the bearing arm 1 is not convenient to disassemble, and the optimal straightening mode is to install the straightening device near the bending part of the transverse amplitude rod 11, so that the bending part of the transverse amplitude rod 11 is straightened on the premise of not disassembling the transverse amplitude rod 11; in order to enable the clamping component 21 in the straightening device to realize the effect of clamping on the rod body of the banner rod 11, in an embodiment, the two clamping components 21 have the same structure; any one of the clamping assemblies 21 comprises a mounting frame 211, a first clamping plate 212, a second clamping plate 213, a plurality of fastening bolts 214 and a plurality of nuts 215; the top end of the mounting bracket 211 is connected with the support rod 4, and the bottom end of the mounting bracket 211 is fixedly connected with the first clamping plate 212; the first clamping plate 212 and the second clamping plate 213 are symmetrically arranged on two sides of the banner pole 11 and connected through a fastening bolt 214, and the fastening bolt 214 and a nut 215 are matched to reduce the distance between the first clamping plate 212 and the second clamping plate 213, so that the banner pole 11 is clamped and fixed.
The first clamping plate 212 and the second clamping plate 213 are used for clamping the bar body of the transverse amplitude bar 11 from two sides of the transverse amplitude bar 11; the fastening bolt 214 sequentially passes through the first clamping plate 212 and the second clamping plate 213, nuts 215 are sleeved at two ends of the fastening bolt 214 for positioning and locking, and the first clamping plate 212 and the second clamping plate 213 are close to each other by screwing the nuts 215, so that the banner rod 11 between the two clamping plates is clamped firmly. The mounting frame 211 is used for connecting the supporting rod 4, the length of the mounting frame 211 is the distance between the supporting rod 4 and the transverse amplitude rod 11, and the mounting frame 211 with a proper length is selected to match the size of the pressing mechanism, so that the jacking mechanism 3 can be placed between the supporting rod 4 and the bending part of the transverse amplitude rod 11 after the clamping mechanism 2 is fixed.
Based on the above scheme, since the pressing mechanism 3 only needs to apply a pressure perpendicular to the length direction of the support rod 4 to the bending portion of the banner rod 11 when the banner rod 11 is straightened, and the support rod 4 does not need to be constrained along the length direction of the support rod 4, in order to simplify the dismounting/mounting steps of the support rod 4, in an embodiment, the top end of the mounting bracket 211 is provided with a sleeve 216; the sleeve 216 is slidably sleeved on the support rod 4.
The mounting frame 211 can be connected with the support rod 4 in a sleeved mode, so that the disassembling/assembling steps of the support rod 4 and the mounting frame 211 are simplified, and the working efficiency of the straightening device is improved.
Based on the above scheme, when the jacking mechanism 3 jacks and straightens the bending portion of the transverse rod 11 with the support rod 4 as a fulcrum, if the surface of the support rod 4 is a curved surface, the jacking mechanism 3 is prone to slip off from the contact surface of the support rod, or the jacking mechanism 3 slips off due to the rotation of the cylindrical support rod 4 in the circular sleeve 216; therefore, in one embodiment, the support rod 4 is a prism; the cavity of the sleeve 216 is a prism-shaped cavity matching the shape of the support rod 4.
The supporting rod 4 is designed by adopting a prism, so that a plane for the top pressing mechanism 3 to stably support is formed on the surface of the supporting rod 4; meanwhile, the cavity shape of the sleeve 216 is matched with the shape of the support rod 4, and the support rod 4 with the ridge structure is matched with the sleeve 216 to form a stable structure of spline connection, so that the support rod 4 is prevented from rotating.
Based on the above solution, since the first clamping plate 212 and the second clamping plate 213 are both flat plate structures, in order to avoid deflection or sliding during clamping the bar body of the banner bar 11, in an embodiment, the clamping surface of the first clamping plate 212 is provided with a first reinforcing member 217; a second reinforcing member 218 is arranged on the clamping surface of the second clamping plate 213; the first reinforcing member 217 and the second reinforcing member 218 are symmetrically clamped on both sides of the banner pole 11.
A first stiffener 217 and a second stiffener 218 are respectively disposed on the clamping surfaces of the first clamping plate 212 and the second clamping plate 213, and the stiffeners are used for matching the shape of the banner pole 11 so as to achieve the effect of maintaining the stability of the pole body of the banner pole 11.

The contact surfaces of the first reinforcing member 217 and the second reinforcing member 218 for clamping the transverse amplitude rod 11 are smooth curved surfaces, and the smooth curved surfaces are tangent to the surface of the transverse amplitude rod 11, so that the surface of the transverse amplitude rod 11 is subjected to radial clamping force towards the axis of the transverse amplitude rod 11 to keep stability, and the clamping and stabilizing effect of the transverse amplitude rod 11 can be improved.
Based on the above scheme, in order to avoid that the restraining effect of the clamping mechanism 2 on the banner bar 11 is reduced due to the looseness of the first reinforcing member 217 and/or the second reinforcing member 218, so as to affect the straightening effect, in an embodiment, the first reinforcing member 217 is integrally formed with the first clamping plate 212; the second reinforcement member 218 is integrally formed with the second clamping plate 213.
The first reinforcing member 217 is integrally formed with the first clamping plate 212, and the second reinforcing member 218 is integrally formed with the second clamping plate 213; the integral forming process can adopt conventional processing techniques such as casting, injection molding, stamping, carving and the like, and the details are not described herein.
Based on the above scheme, if the friction coefficient of the contact surface between the supporting rod 4 and the pressing mechanism 3 is not sufficient, the pressing mechanism 3 is prone to be loosened when the pressing mechanism 3 works, and therefore, in an embodiment, the first anti-slip block 31 is disposed at one end of the pressing mechanism 3, which is abutted against the supporting rod 4.
The first anti-slip block 31 is used for increasing the friction force of the contact surface of the jacking mechanism 3 and the support rod 4, and preventing the jacking mechanism 3 from loosening from the surface of the support rod 4. The first anti-slip block 31 can be a rubber anti-slip block, a silica gel anti-slip block or a leather anti-slip block.
Based on the above scheme, if the surface friction coefficient of the pressing mechanism 3 and the bending portion of the banner bar 11 is not sufficient, the pressing mechanism 3 is likely to shift and slide during operation, so that the stressed direction of the banner bar 11 shifts and aligns to cause secondary bending, and therefore, in an embodiment, a second anti-slip block 32 is disposed at one end of the pressing mechanism 3, which is in contact with the convex surface of the bending portion of the banner bar 11.
The second anti-slip block 32 is used for increasing the friction force between the jacking mechanism 3 and the surface of the transverse amplitude rod 11, so as to prevent the jacking mechanism 3 from sliding and deviating, and thus the bending part of the transverse amplitude rod 11 is subjected to pressure deviating from the straightening direction to generate secondary bending. The second anti-slip blocks 32 can be rubber anti-slip blocks, silica gel anti-slip blocks or leather anti-slip blocks.
Based on the above scheme, in order to reduce the manufacturing cost of the straightening device and simplify the operation steps, in an embodiment, the jacking mechanism 3 is a jack.
In order to reduce the cost of the straightening device; meanwhile, the operation flow is simplified, the effects of instant installation and use and rapid straightening are realized, and the jacking mechanism 3 adopts a jack. The jack is convenient to operate, the jacking amplitude is easy to control, the straightening work can be conveniently and quickly completed, and secondary bending of the transverse amplitude rod 11 caused by out-of-control jacking amplitude is avoided.
