Description

Technical Field

[0001] The present invention relates to a working method, in particular to a working method of a power pole without jacking, which belongs to the field of power poles. Background Art

[0002] The existing power pole installs standard sections in sequence through a jacking mechanism. The jacking mechanism is installed on the bottommost standard section, and one standard section is jacked and installed in sequence. This installation method has a very high cost for the jacking mechanism. When the height of the power pole is relatively high, the weight of the standard section plus the slewing platform and the boom is very large, and the jacking oil cylinder needs to have sufficient torque output. When the weight is relatively heavy, the jacking installation also causes relatively large damage to the standard section structure of the power pole itself.

[0003] Therefore, it is particularly necessary to provide a power pole without jacking with reasonable structural design, safety and reliability, and low installation cost. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the prior art, and provide a working method of a power pole without jacking with reasonable structural design, safety and reliability, convenient operation, and low installation cost.

[0005] The technical solution adopted by the present invention to solve the above problems is: the working method of the power pole without jacking includes a standard section dragging structure, an electromagnetic switch control structure, and a ground guide rail. The standard section dragging structure includes a hoisting mechanism, a steel wire rope, a pulley support rod, a support rod lower pulley, a support rod upper pulley, and multiple standard sections. The pulley support rod is fixed on the first standard section, and the support rod lower pulley and the support rod upper pulley are installed on the pulley support rod. The hoisting mechanism is connected to the support rod lower pulley and the support rod upper pulley respectively through the steel wire rope. Each standard section is provided with a slide rail, multiple suspension rings, and multiple rollers. Its characteristics are as follows: including the following steps:

[0006] (S1) After the ground foundation of the power pole is poured, install the first standard section and the ground guide rail. The ground guide rail is aligned with the concave slide rail of the standard section and is fixed to the first standard section and the ground respectively. The other standard sections after the first standard section are lined up and aligned in sequence;

[0007] (S2) There are two hoisting mechanisms. Fix the two motors of the two hoisting mechanisms on the ground. The two motors are respectively connected to the two hoisting mechanisms. The pulley support rod is fixed on the first standard section, and the height of the support rod lower pulley is higher than the height of a single standard section;

[0008] (S3) The hoisting mechanism has double ropes. The steel wire rope of one hoisting mechanism passes through the support rod upper pulley and is connected to the first suspension ring and the second suspension ring of the second standard section. The steel wire rope of the other hoisting mechanism passes through the support rod lower pulley and is connected to the third suspension ring and the fourth suspension ring of the second standard section;

[0009] (S4) The two motors of the two hoisting mechanisms rotate to control the angle of the standard section and pull the standard section. The rollers of the second standard section move on the slide rail of the first standard section until the second standard section is perpendicular to the first standard section. The installer fixes the connecting pin according to the existing method of the electric pole.

[0010] (S5) There are four electromagnetic switch control structures. The four electromagnetic switch control structures are connected in parallel to the socket on the standard section and connected to the control plug of the ground power supply. After connecting to the socket, the switch of the electromagnetic switch control structure is powered on and the rollers retract. When the plug is pulled out, the switch of the electromagnetic switch control structure loses power and the rollers pop out.

[0011] (S6) Install the subsequent continuous standard sections in sequence according to steps (S4) and (S5) until the installation of the last standard section is completed. Lift the rotary platform on the ground above the last standard section and fix it.

[0012] Preferably, the standard section dragging structure of the present invention further includes standard section baffles, and standard section baffles are arranged on the left and right sides of each standard section; to prevent the second standard section from falling off.

[0013] Preferably, there are four rollers in the present invention, and the retraction and extension of the four rollers are all controlled by four electromagnetic switch control structures.

[0014] Compared with the prior art, the present invention has the following advantages and effects: The overall structure is reasonably designed, safe and reliable, easy to operate, low installation cost, there are slide rails, multiple lifting rings and multiple rollers on the standard section, and the rollers have a retractable function through the electromagnetic switch control structure.

Specific implementation manner

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, and the present invention is not limited to the following embodiments.

[0021] Embodiment

[0022] See Figures 1 to 4 , the non-lifting power pole of this embodiment includes a standard section dragging structure, an electromagnetic switch control structure 15 and a ground guide rail 13. The standard section dragging structure includes a hoisting mechanism 1, a wire rope 2, a pulley support rod 3, a lower pulley 4 of the support rod, an upper pulley 5 of the support rod and a plurality of standard sections 7. The pulley support rod 3 is fixed to the first standard section, and the lower pulley 4 of the support rod and the upper pulley 5 of the support rod are installed on the pulley support rod 3.

[0023] In this embodiment, the hoisting mechanism 1 is connected to the lower pulley 4 of the support rod and the upper pulley 5 of the support rod respectively through the wire rope 2. A standard section main body 16, a socket 17, an electromagnetic switch 18, a slide rail 14, a plurality of lifting rings 9 and a plurality of rollers 10 are arranged on each standard section 7.

[0024] The specific steps of the non-lifting power pole of this embodiment are as follows:

[0025] (S1) After the ground foundation of the power pole is poured, install the first standard section and the ground guide rail 13. The ground guide rail 13 is aligned with the concave guide rail 14 of the standard section and is fixed to the first standard section and the ground respectively. The second, third, fourth... standard sections are lined up and aligned in sequence;

[0026] (S2) Fix two motors on the ground and connect them to the hoisting mechanism 1 respectively. First, fix the pulley support rod 3 to the first standard section. There are a lower pulley 4 of the support rod and an upper pulley 5 of the support rod on the pulley support rod 3. The height of the lower pulley 4 of the support rod is higher than the height of a single standard section;

[0027] (S3) The two hoisting mechanisms 1 have double rope exits. The steel wire rope 2 of one hoisting mechanism 1 passes through the upper support pulley 5 on the pulley support rod 3 and is connected to the first sling and the second sling corresponding to the second standard section. The steel wire rope 2 of the other hoisting mechanism 1 passes through the lower support pulley 4 on the pulley support rod 3 and is connected to the third sling and the fourth sling corresponding to the second standard section.

[0028] (S4) The two motors of the two hoisting mechanisms 1 rotate to control the angle of the standard section and pull the standard section. The rollers 10 of the second standard section move on the slide rail 14 of the first section until the second standard section is perpendicular to the first standard section. The installer fixes the connecting pin according to the existing method of the electric derrick. There is a standard section baffle 6 on each side of the left and right of each standard section to prevent the second standard section from falling off.

[0029] (S5) There are four rollers 10 on each standard section. The retraction and extension of the rollers 10 are controlled by the four electromagnetic switch control structures 15. The four electromagnetic switch control structures 15 are connected in parallel to the socket 17 on the standard section. After the control plug connecting to the ground power supply is connected to the socket, the electromagnetic switch is powered on and the rollers 10 retract. When the plug is pulled out, the electromagnetic switch control structure 15 loses power and the rollers 10 pop out.

[0030] (S6) Install the 3rd, 4th, 5th... standard sections in sequence according to steps S4 and S5 until the installation of the last standard section is completed. Lift the rotary platform on the ground above the last standard section and fix it.

[0031] See Figure 4 As shown, the electromagnetic switch control structure 15 in this embodiment includes a moving magnetic pole connecting rod 151, a moving magnetic pole 152, a static magnetic pole 153, an electric baffle bar 154, an upper stop block 155, a lower stop block 156 and a wire 157. The principle of the electromagnetic switch control structure 15: After the wire 157 is powered on, the electric baffle bar 154 slides to the right. At the same time, the moving magnetic pole 152 and the static magnetic pole 153 attract each other, driving the roller 10 and the moving magnetic pole connecting rod 151 to retract the roller 10. After two seconds of delay (there is a time relay in the electric baffle bar 154), the electric baffle bar 154 moves to the left and is blocked by the lower stop block 156. At this time, the roller 10 is also in the retracted state when powered off. When the wire 157 is powered off and then powered on again, the electric baffle bar 154 slides to the right. At the same time, the moving magnetic pole 152 and the static magnetic pole 153 repel each other, driving the roller 10 and the moving magnetic pole connecting rod 151 to retract and pop out the roller 10. After two seconds of delay (there is a time relay in the electric baffle bar 154), the electric baffle bar 154 moves to the left and is blocked by the upper stop block 155. At this time, the roller 10 is also in the popped state when powered off.

[0032] The system of this embodiment is an installation method in which the ground hoisting mechanism pulls the standard section in sequence.
