Technical Field

[0001] The utility model belongs to the field of tower transportation, in particular to a piece-type wind power tower loading and transportation tooling. Background Art

[0002] In the field of wind power, the tower is the main load-bearing component of the wind turbine. As the power of the generator increases, the size and weight of the tower are also getting larger and larger. Therefore, in order to meet the requirements of tower transportation and height limit, large-diameter towers are usually divided into pieces and stacked with tooling during transportation. This can reduce the use of vehicles and realize complete set transportation.

[0003] The existing tools that can realize the stacking and transportation of segmented wind turbine towers include: the Chinese patent with application date of 2023-07-24 and application number of CN202321950072.3 discloses a tool for transporting segmented towers, which is suitable for most segmented tower transportation, easy to lift, and stable and reliable. However, this work has the following defects:

[0004] 1. The upper end of the tooling body is fixedly mounted with a first clamping plate and a second clamping plate, and the first clamping plate and the second clamping plate are clamped and mounted on the inner end of the connecting groove, and the connecting groove is provided at the bottom of the tooling body. In this structure, the first clamping plate and the second clamping plate play a role of limiting and anti-slipping, so they need to have a certain thickness requirement, which will cause the tooling body to be made very thick to meet the anti-slipping requirement, thus making the tooling very bulky;

[0005] 2. After the first clamping plate and the second clamping plate are inserted into the connection groove, they are fixed by bolts, which is troublesome to operate;

[0006] 3. It is necessary to set up an additional suspension device on the main body of the tooling, which makes the tooling production more complicated and the production cost higher;

[0007] 4. It is made of bottom support parts, and the connection stability between it and the transport vehicle is not high.

[0008] Based on this, the present application provides a segmented wind turbine tower loading and transport tooling with a more reasonable structural design, low manufacturing cost, and the ability to be stably connected to a transport vehicle. Utility Model Content

[0009] The utility model aims to solve the problems of the existing transport tooling, such as complex structure, heavy tooling, high manufacturing cost, and low connection stability with the transport vehicle. To this end, the utility model provides a segmented wind turbine tower loading and transport tooling with a more reasonable structural design, low manufacturing cost, and stable connection with the transport vehicle.

[0010] The technical solution adopted by the utility model to solve its technical problems is:

[0011] A segmented wind turbine tower loading and transport tool is provided, comprising a base installed on a transport vehicle and a support assembly installed on the base for fixing the tower; the support assembly comprises a support plate and at least one positioning member arranged on the front side of the support plate, wherein: both ends of the support plate are provided with support arms extending out of their top planes, and the support arms are provided with a plurality of fixing holes connected to the tower flange by bolts; the positioning member comprises a locking seat welded to the front side of the support plate, a locking pin arranged on the side of the locking seat and a positioning pin arranged at the bottom of the locking seat, the locking seat is provided with a socket adapted to the positioning pin, and the positioning pin is provided with a limiting groove plugged with the locking pin; the two support assemblies are stacked and connected by plugging the positioning pin into the locking seat.

[0012] Preferably, the locking pin is a knob plunger.

[0013] Preferably, the bottom of the positioning pin is arranged as a conical surface, and the pin rod end of the locking pin is arranged as an extrusion slope.

[0014] Preferably, a guide hole is provided at the opening of the jack.

[0015] Preferably, a locking seat with a locking pin which is plugged into the positioning pin is provided on the base.

[0016] Preferably, an electromagnet is embedded in the bottom of the base.

[0017] Preferably, a rib plate is further provided on the front side of the support plate.

[0018] Preferably, the height of the locking seat is equal to the width of the supporting plate.

[0019] Preferably, the ends of the support arms at both ends of the support plate are also provided with hanging holes.

[0020] In a preferred embodiment, the transport tooling further comprises a securing device, which comprises a pull cable and a basket nut, wherein the pull cable passes through the lifting hole of the support plate and / or passes around the pull ring of the tower and the transport vehicle to be connected to the basket nut.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The utility model sets a positioning piece on the front of the support plate, and realizes the stacking connection of the upper and lower support components by plugging and connecting the positioning pieces. Compared with the existing transport tooling, this design has lower requirements on the thickness of the support plate, can effectively reduce the weight of the tooling, reduce the production cost, and is also easy to install;

[0023] Second, the height of the locking seat of the positioning member is equal to the width of the support plate. This design allows the weight of the upper support assembly and the tower to be borne by the locking seat, while the support plate only bears the weight of the tower on this layer. Compared with relying entirely on the support plate to bear the weight of the upper layer, this tooling can significantly reduce the load requirements for the support plate, thereby reducing the manufacturing cost;

[0024] 3. The upper and lower support components are locked by locking pins, and the locking pins use knob plungers, which are easy to operate. Compared with the method of fixed connection with bolts, the operation is simpler;

[0025] Fourth, the hanging holes are made by digging holes on the support plate. Compared with the traditional method of welding the hanging device on the front of the support plate, it is simpler to make and has lower cost;

[0026] 5. An electromagnet is arranged on the base, which can be fixed on the transport vehicle by magnetic attraction; and a pulling device is further arranged to ensure the stability of the transport tooling on the transport vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, two positioning members are preferably provided. The two ends of the support plate 2.1 are provided with support arms 2.1.1 extending out of the top plane thereof. The support arms 2.1.1 are provided with a plurality of fixing holes connected to the tower flange by bolts, and the flanges at both ends of the tower are connected to the support arms by bolts. The positioning member includes a locking seat 2.2 welded to the front of the support plate 2.1, a locking pin 2.3 arranged on the side of the locking seat 2.2, and a positioning pin 2.4 arranged at the bottom of the locking seat 2.2; the locking seat 2.2 is provided with a socket 2.2.1 adapted to the positioning pin 2.4, and the positioning pin 2.4 is provided with a limiting groove 2.4.1 plugged with the locking pin 2.3. The two support assemblies arranged above and below are inserted into the socket of the locking seat by the positioning pin and locked by the locking pin, thereby realizing stacking connection.

[0041] Preferably, the locking pin 2.3 of this embodiment adopts a knob plunger, which is simpler to operate than the method of fixed connection using bolts.

[0042] Preferably, the bottom of the positioning pin 2.4 is set as a conical surface, and the pin end of the locking pin 2.3 is provided with an extrusion slope. In this design, when the upper support assembly is inserted into the lower support assembly, there is no need to operate the locking pin, and the locking pin can be directly inserted by using the conical surface of the positioning pin to squeeze the extrusion slope of the locking pin. When unlocking is required, it is only necessary to pull out the knob plunger and rotate it by an angle, and the pin will then be out of the limit groove.

[0043] Preferably, the opening of the plug hole 2.2.1 is provided with a guide hole 2.2.2, so that the upper and lower support components can automatically find their positions through the guide hole when plugged in.
