To this end, the present embodiment provides one possible implementation of the mobile support 200 as follows:
as shown in fig. 1, the moving support 200 of the embodiment of the present application includes: a first moving support 210 and a second moving support 220;
the first mobile support 210 is located within the tower or tower section 1; the second mobile support 220 is located outside the tower or tower section 1; the second moving support 220 is mated with and may be coaxially connected to the first moving support 210.
In this embodiment, the movable support 200 is divided into two sections, namely a first movable support 210 and a second movable support 220, which can be coaxially spliced, so that the length of the single-section movable support 200 is reduced while the movable support 200 is extended, and the production difficulty or the transportation difficulty is reduced.

The support body with a rolling surface located inside the tower or tower segment 1 may be a part of the inner wall of the tower or tower segment 1.
The inventor of the present application considers that the support bracket 110 of the jig main body 100 provides mounting support for the accessory restrainer 120, the support mechanism 130, and the moving member, and provides sufficient load strength for the entire jig main body 100. For this reason, the present embodiment provides the following possible implementation manner for the supporting frame 110:
as shown in fig. 4 and 5, the support bracket 110 of the embodiment of the present application includes: a first support bracket 110a and a second support bracket 110 b;
the first support frame 110a includes: a first base 111a, a first stand 112a, and a first inclined bracket 113 a; one end of the first upright frame 112a is connected with the first base 111a, one end of the first inclined bracket 113a is connected with the other end of the first upright frame 112a, and the other end of the first inclined bracket 113a is connected with one end of the first base 111a far away from the first upright frame 112 a;
the second supporter 110b includes: a second base 111b, a second upright 112b, and a second inclined bracket 113 b; one end of the second upright frame 112b is connected with the second base 111b, one end of the second inclined bracket 113b is connected with the other end of the second upright frame 112b, and the other end of the second inclined bracket 113b is connected with one end of the second base 111b far away from the second upright frame 112 b;
the first stand 112a and the second stand 112b are oppositely connected through a detachable connecting piece 140;
the accessory limitation piece 120 is fixedly connected with one side of the first stand 112a facing the second stand 112 b;
the first base 111a and the second base 111b are connected with the moving part;
the support mechanism 130 is connected to a side of the second base 111b facing the accessory restriction member 120.
In this embodiment, the first base 111a, the first upright frame 112a and the first inclined bracket 113a of the first support frame 110a form a triangular rear quasi-triangular connection structure therebetween, so that the first support frame 110a is stable enough to support the tower attachment 2 and the tower equipment 3. The second supporting frame 110b has the same structure as the first supporting frame 110a, and thus, the description thereof is omitted.
The first stand 112a of the first support frame 110a is detachably connected with the second stand 112b of the second support frame 110 b. When the tower attachment 2 is installed, the first vertical frame 112a and the second vertical frame 112b are connected, and the first support frame 110a and the second support frame 110b form a whole, so that the jig main body 100 carrying the tower attachment 2 and the tower equipment 3 can be conveniently and smoothly moved into the tower or the tower section 1. In addition, the first support frame 110a and the second support frame 110b are arranged oppositely, and the first inclined support 113a and the second inclined support 113b can balance the overturning force of the first vertical frame 112a generated by bearing the tower attachment 2 and the tower device 3, so as to avoid the risk of the rollover of the whole jig main body 100.

Because the tower drum or the tower drum section 1 is lifted immediately after the support of the support mechanism 130 to the tower drum equipment 3 is removed, the tower drum or the tower drum section 1 is turned from a prone position to a standing position, the turning process time is short, the fixing strength between the tower drum equipment 3 and the tower drum accessory 2 and the fixing strength between the tower drum accessory 2 and the tower drum or the tower drum section 1 are enough to bear respective loads, namely after the support of the support mechanism 130 to the tower drum equipment 3 is removed, the tower drum accessory 2 cannot overturn, and the tower drum equipment 3 cannot fall off.
Alternatively, the detachable connector 140 is a split bolt, and a tie between the first stand 112a and the second stand 112b may be implemented. The split bolt can be a round steel bolt with two end mantle wires, or a flat steel bolt with two ends provided with long holes and wedged tightly by inserting wedge-shaped iron.
It should be understood that, in the present embodiment, the accessory limiting member 120 is connected to the first vertical frame 112a, and the supporting mechanism 130 is connected to the second base 111b, but it is also possible to adopt a manner that the accessory limiting member 120 is connected to the second vertical frame 112b, and the supporting mechanism 130 is connected to the first base 111a, that is: the accessory limiting member 120 is fixedly connected to a side of the second stand 112b facing the first stand 112a, and the support mechanism 130 is connected to a side of the first base 111a facing the accessory limiting member 120.
On the basis of the above-described embodiments, the inventors of the present application provide a further balancing structure for the overturning forces generated by the carrying of the tower attachment 2 and the tower apparatus 3. For this reason, the present embodiment provides one possible implementation manner for the first support frame 110a as follows:
the first support frame 110a of the embodiment of the present application further includes: a counterweight (not shown);
the counterweight block is connected with one end of the first base 111a far away from the first stand 112 a;
or, the counterweight is connected to a side of the first stand 112a facing away from the second stand 112 b.
In this embodiment, the weight block may further balance the overturning force of the jig main body 100 generated by bearing the tower drum accessory 2 and the tower drum device 3, so that the whole jig main body 100 bearing the tower drum accessory 2 and the tower drum device 3 is safer.
It is understood that if the accessory limiting member 120 is connected to the second standing frame 112b and the supporting mechanism 130 is connected to the first base 111a, the counterweight can be disposed on the second supporting frame 110b, that is: the second support bracket 110b further includes: a balancing weight; the counterweight block is connected with one end of the second base 111b far away from the second vertical frame 112 b; or, the counterweight is connected to a side of the second stand 112b facing away from the first stand 112 a.
The present embodiment further provides another possible implementation manner for the supporting frame 110 as follows:
as shown in fig. 6, the support bracket 110 of the embodiment of the present application includes: a base 111, a stand 112 and a diagonal bracket 113;
one end of the vertical frame 112 is connected with the base 111, one end of the inclined bracket 113 is connected with the other end of the vertical frame 112, and the other end of the inclined bracket 113 is connected with one end of the base 111 far away from the vertical frame 112;
the accessory limiting piece 120 is fixedly connected with one side of the stand 112 facing the base 111;
the base 111 is connected with the moving part;
the support mechanism 130 is connected to a side of the base 111 facing the accessory restraint 120.
The structure of the single support frame 110 adopted in the embodiment simplifies the structure of the jig main body 100, and can also save the manufacturing cost. The accessory limiting part 120 and the supporting mechanism 130 are located on the same side of the vertical frame 112, so that the gravity center of the jig main body 100 and the gravity center of the tower drum accessory 2 provided with the tower drum equipment 3 are kept in the space between the vertical frame 112 and the base 111, the overall balance of the jig main body 100 bearing the tower drum accessory 2 and the tower drum equipment 3 can be kept, and the overall safety of the jig main body 100 bearing the tower drum accessory 2 and the tower drum equipment 3 is also realized.
The present inventors have recognized that the accessory restraint 120 needs to provide stable securement and load bearing for the tower accessory 2. To this end, the present embodiment provides one possible implementation of the accessory restraint 120 as follows:
