Description

Technical Field

[0001] The utility model relates to the technical field of angle steel tower welding equipment, in particular to an assembled butt joint structure and angle steel tower welding equipment for large-scale safe power transmission. Background Art

[0002] Large angle steel towers for safe power transmission, also known as transmission towers, are important structures used to support and erect high-voltage transmission lines in power systems. Large angle steel towers for safe power transmission are composed of tower heads, tower bodies, tower legs, guy wire parts, cross arms, foundations, etc. Among them, the tower body, tower head and cross arms are the main parts that occupy the largest volume of the transmission tower. The tower body and tower head are distributed perpendicular to the ground, while the cross arms are distributed parallel to the ground. The tower head is installed at the top of the tower body, and the cross arms are installed on both sides of the tower head.

[0003] In the prior art, the installation between the crossarm and the tower head is usually to assemble and connect the crossarm and the tower head together and then weld the two together. The assembly and connection work of the crossarm and the tower head is carried out after the tower head and the tower body are installed. The crossarm is hoisted to the same height as the tower head by a helicopter, and then the workers who climb onto the tower head manually pull the crossarm to align the screw holes on the surface of the crossarm with the screw holes reserved on the tower head. Finally, the two are pre-fixed with bolts to complete the assembly and connection of the crossarm and the tower head. This method of assembling and connecting first and then welding and reinforcing can reduce the helicopter's hovering time, save fuel, and also reduce the difficulty of welding.

[0004] However, in the prior art, when assembling and docking the crossarm with the tower head, workers are required to manually pull the crossarm to the corresponding position, which is very laborious. When the height and angle of the crossarm screw hole deviate from the height and angle of the tower head reserved hole, it is very difficult to adjust the deviation by lifting the helicopter. In addition, this adjustment work also causes the helicopter to remain in the air for a long time. Utility Model Content

A screw sleeve 11 is rotatably connected to the bottom end of the base 1. The screw sleeve 11 is a circular cylindrical structure. The screw sleeve 11 is sleeved on the surface of the screw 12. The inner ring of the screw sleeve 11 is provided with a thread, and the thread of the screw sleeve 11 matches the thread of the screw 12. A passive gear 10 is fixed to the outer ring surface of the screw sleeve 11, and the passive gear 10 is meshed with the driving gear 9. A plurality of groups of guide holes 14 are provided on the surface of the base 1, and the plurality of groups of guide holes 14 are distributed circumferentially about the screw hole 13.

The base 1 is installed on the tower head through the fixing plate 3. When the tower head and the cross arm are assembled and connected, the helicopter lifts the cross arm to the same height as the tower head, and then places the cross arm on the top of the supporting plate 5. Then the push rod of the second hydraulic push rod mechanism 6 is slightly extended, and the steel cable arranged parallel to the push plate 7 on the cross arm is pressed under the cross plate of the push plate 7. Then the cross arm and the supporting plate 5 can be pre-fixed, and the connection between the helicopter and the cross arm can be released to evacuate the helicopter. Afterwards, the height of the supporting plate 5 can be adjusted by adjusting the height of the screw 12 in the screw hole 13, and then the height of the cross arm can be fine-tuned. The elongation and shortening of the push rod mechanism 4 can adjust the angle between the base 1 and the fixed plate 3, and then fine-tune the angle of the cross arm.

The subsequent adjustment work is carried out by the push rod of the first hydraulic push rod mechanism 4 to adjust the angle of the cross arm, and the screw 12 is adjusted by the up and down movement of the screw hole 13. The height adjustment of the cross arm is carried out, and the extension of the second hydraulic tappet mechanism 6 brings the cross arm closer to the tower head, which greatly shortens the hovering time of the helicopter and saves the manpower required for adjusting the height and angle of the cross arm. Large angle steel towers for safe power transmission of different specifications often have different sizes of tower heads, and the distances between the longitudinal beams constituting the tower heads are also different. In order to enable the assembled docking structure to be installed on tower heads of various sizes, a guide rail 2 is provided at one end of the base 1, and the fixing plate 3 is rotatably connected to the first slider in the guide rail groove of the guide rail 2. A second slider is provided at the top of the connecting seat 16, and the second slider is slidably connected to the slide groove 17. The two sets of fixed The distance between the plates 3 enables the fixed plate 3 to be installed on tower heads of various sizes; when the transmission shaft of the motor 8 drives the active gear 9 to rotate, the active gear 9 drives the passive gear 10 to rotate, and the passive gear 10 drives the screw sleeve 11 to rotate, and at the same time, the screw 12 is fixed to the bottom end of the supporting plate 5, and the bottom end of the supporting plate 5 is also fixed with a plurality of groups of guide rods 15, and the plurality of groups of guide rods 15 are inserted in the guide holes 14, so that the supporting plate 5 cannot rotate, and the screw 12 cannot rotate. Therefore, when the screw sleeve 11 rotates and the screw 12 does not rotate, the screw sleeve 11 and the screw 12 can be connected by the threaded connection to make the screw 12 move up and down in the screw hole 13, so that the height of the screw 12 in the screw hole 13 can be adjusted;The diameter of the bottom end of the guide rod 15 is larger than the diameter of the guide hole 14, so after the support plate 5 moves upward to a certain extent, the guide rod 15 will abut against the bottom end of the base 1, thereby preventing the support plate 5 from moving upward excessively and detaching from the surface of the base 1. ;
