Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pole erection, in particular to a whole pole erection device and a use method thereof. BACKGROUND

[0002] In the construction process of the tower with the suspended pole, the pole erection is usually assisted by the inverted V-shaped pole. The inverted V-shaped pole erection has many processes, and many ropes are used. The inverted V-shaped pole is complex to fall. After the pole erection is erected to the position, high-altitude personnel need to climb the pole to remove the binding points. The construction operation surface requires a wide range.

[0003] The existing pole erection by the inverted V-shaped pole has the following disadvantages:

[0004] (1) Complex process

[0005] The pole erection has the following processes from the beginning to the end: arranging the tower pole and the upward pulling line, arranging the inverted V-shaped pole, arranging the tower pole binding rope, arranging the inverted V-shaped pole falling pulling line, arranging the traction system, erecting the tower pole to a certain position, falling the inverted V-shaped pole, erecting the tower pole to the position, and removing the erection system rope. After the above processes are completed, the tower pole erection is completed.

[0006] (2) Many construction tools

[0007] The traditional method needs many tools, such as the inverted V-shaped pole, the inverted V-shaped pole leg connecting rope, the inverted V-shaped pole temporary pulling line, and the traction rope. Many ropes are arranged on the site.

[0008] (3) Complex inverted V-shaped pole falling

[0009] After the tower pole is erected to a certain position, the inverted V-shaped pole needs to be fallen. When the traction system rope is perpendicular to the inverted V-shaped pole support plane, the inverted V-shaped pole is no longer stressed. At this time, the tower pole erection is stopped, the inverted V-shaped pole hawk mouth is automatically dropped, and the inverted V-shaped pole pulling line is slowly released to make it fall to the ground under the action of gravity. The time point, speed, and position of the inverted V-shaped pole falling need to be controlled. The command personnel and the operator need to have rich work experience to master the skill.

[0010] (4) Large amount of high-altitude operation

[0011] After the tower pole is erected to the position, high-altitude personnel need to climb the pole to remove the binding points. There are two binding points on the tower pole. When the tower pole is erected to the vertical position, the binding points bear the traction rope, the inverted V-shaped pole falling pulling line, and the gravity of the tower pole. Two high-altitude personnel need to climb to the binding points to remove the binding rope and then slowly release it to the ground. Moreover, with the increase of the length of the tower pole, the binding points are higher, the high-altitude personnel need to climb higher, and the amount of work is larger.

[0012] (5) The construction work area requires a wide range.

[0013] In addition to the four guy wires of the gantry being grounded around the tower location, the location of the A-frame gantry's fall, the location of the guy wires, and the location of the traction system also need to be considered. Due to the limited area of ​​the tower erection site, the placement of a large number of tower materials and tools needs to be arranged reasonably. If the area occupied by the tower erection gantry is too large, it will affect the stacking of tower materials. The tower materials can only be transported to the site gradually after the tower erection gantry is completed, which will affect the work efficiency. Summary of the Invention

[0067] The method for using the embrace pole overall erecting device of the embodiment comprises the following steps:

[0068] (1) Site leveling

[0069] According to the topography of the tower site, the erecting direction of the embrace pole 4 and the placing position of the overall erecting device are selected, so that the embrace pole 4 is erected and the embrace pole 4 is just placed in the center of the foundation after the embrace pole 4 is erected, the position is selected, the base surface is leveled, the base surface should be firm, the size should meet the operation space of the overall erecting device, and the ground on which the embrace pole 4 is placed and the overall erecting device should be on the same slope or the same horizontal surface in the same direction, so as to prepare for the next step.

[0070] (2) Arranging the embrace pole overall erecting device

[0071] The embrace pole overall erecting device is directly placed on the leveled base surface; whether each component is intact, whether the component assembly is correct, and whether the operation is reliable are checked, and the next step operation can be performed if there is no problem.

[0072] Four shackles 5 are used at the four corners to connect to the through holes 15 on the base plate 11.

[0073] (3) Arrange the tower support poles and guy wires

[0074] Assemble the pole 4 along the length of the overall erecting device. Place the bottom end of the pole 4 on the rotating seat 2 of the overall erecting device, ensuring that the pole 4 rests precisely on the ground at the center pile position of the tower after erection. Insert the long bolt 8 through the two pairs of identical slotted holes 26 on the double-hinged seat 24 of the rotating seat 2 from bottom to top. The long bolt 8 then passes through the slotted holes at both ends of the fixing strip 9. Tighten the nuts to make the fixing strip 9 firmly press the pole 4, thereby fixing the pole 4 to the rotating seat 2.

[0077] (4) Erecting the tower support pole

[0078] After the above work arrangements are completed and all stress-bearing parts are confirmed to be normal, start the jacking device 3 to push the rotating seat 2 of the device to rotate and slowly raise the gantry 4 into place. During the raising process, the four upper tension lines are simultaneously raised and lowered through the rope retractor, always keeping the upper tension lines under slight stress to maintain the stability of the gantry. After the gantry 4 is raised into place, check whether the bottom of the gantry 4 is on solid ground. If it is on solid ground, tighten the upper tension lines to make the gantry 4 in a stable state under stress. Then, arrange for workers to remove the parts fixed to the gantry 4 on the rotating seat 2 and disconnect the tower erection gantry from the raising device. If the bottom of the gantry 4 is not on solid ground or there is a gap between it and the ground, fill it with pads and ensure that the gantry is stable under stress before disconnecting the connection.

[0080] (5) Dismantle the overall lifting device

[0081] The whole device is operated to slowly retract the rotating seat 2, remove the connecting steel wire between the base 1 and the tower leg, and then transport the device to the next tower position or to the warehouse for storage.
