Description

Technical Field

[0001] This application relates to the field of lighting technology, and particularly to a street lamp pole installation structure and an installation method. Background Art

[0002] Street lamps usually consist of lamp poles, lamps and electrical equipment, and different types and powers of street lamps can be selected according to different environments and requirements. In modern cities, street lamps have become an important part of urban infrastructure, and are of great significance for improving night driving safety, beautifying the urban night scene and enhancing the urban image.

[0003] Currently, the bottom ends of most street lamp poles are in a flange shape. The street lamp pole is hoisted by a crane until its bottom end accurately docks with the expansion bolts on the ground, and then nuts are tightened on the expansion bolts.

[0004] The tightening of the above nuts can only be carried out after the street lamp pole is hoisted in place. When unexpected situations occur during the hoisting process, the entire street lamp installation project will come to a complete standstill, and the installation efficiency is low, with obvious deficiencies. Summary of the Invention

[0005] In order to improve the problem of low installation efficiency of street lamp poles, this application provides a street lamp pole installation structure and an installation method.

[0006] In a first aspect, this application provides a street lamp pole installation structure, adopting the following technical solution:

[0007] A street lamp pole installation structure includes a mounting base bolted to the ground. A plurality of radially opened telescopic slots are circumferentially arranged on the mounting base. Telescopic plug plates are slidably arranged in the telescopic slots. Plug slots for plugging and cooperating with the telescopic plug plates are opened on the inner side wall at the bottom of the lamp pole. A receiving hole communicating with each telescopic slot is vertically opened at the top of the mounting base. A telescopic compression spring is braced between the end of the telescopic slot communicating with the receiving hole and the corresponding telescopic plug plate. A wire wheel is rotatably mounted in the receiving hole. A plurality of telescopic pull wires are wound around the wire wheel. One telescopic pull wire corresponds to one telescopic plug plate and is connected to it. A ratchet wheel is coaxially arranged on the wire wheel. A pawl engaging with the ratchet wheel is hinged at a position of the mounting base relative to the receiving hole. An inspection opening is reserved at a position near the bottom of the lamp pole.

[0008] By adopting the above technical solution, the worker rotates the wire reel to synchronously wind up each telescopic stay wire. Each telescopic plug board is received in the corresponding telescopic slot. The telescopic plug board cooperates with the end of the telescopic slot to squeeze the telescopic compression spring. Then, the pawl is rotated to engage with the ratchet wheel. Next, the mounting base is bolted to the planned mounting position on the ground. Subsequently, the crane hoists the lamp post to accurately dock with the mounting base. Then, the worker reverses the pawl through the inspection port to disengage it from the ratchet wheel. The telescopic compression spring pushes the telescopic plug board to extend and engage with the insertion slot, thereby realizing the installation of the street lamp post. Even if an unexpected situation occurs during the hoisting process, the worker can first bolt the mounting base to the ground in advance, thus saving a lot of time and improving the installation efficiency.

[0009] Optionally, a plurality of rotation-limiting slots for plugging and cooperating with the end of the telescopic plug board are circumferentially formed at the position of the lamp post relative to the insertion slot. Two circumferentially adjacent rotation-limiting slots are in close contact. The cross-sections of the end of the telescopic plug board and the rotation-limiting slot are both V-shaped.

[0010] By adopting the above technical solution, the telescopic plug board is plugged and cooperated with the rotation-limiting slot, thereby reducing the possibility of accidental rotation of the street lamp post under the action of external force during use after the installation of the street lamp post is completed.

[0011] Optionally, an installation cylinder is arranged on the top of the mounting base. A ring knife is vertically slidably sleeved on the installation cylinder. A pressure rod for pushing the ring knife to move downward is also arranged on the inner wall of the lamp post. The top of the telescopic slot extends to the top surface of the mounting base. A pre-pressure stay wire is tied to the telescopic plug board. The pre-pressure stay wire passes through the telescopic slot and is tied to a position relative to the lower part of the ring knife on the top of the mounting base.

[0012] By adopting the above technical solution, the worker pre-releases the telescopic stay wire to an appropriate length in advance. When hoisting the lamp post, the pressure rod in the lamp post will contact the ring knife and push it to move downward. In this way, the ring knife cooperates with the mounting base to cut off the pre-pressure stay wire. Then, under the action of the telescopic compression spring, the telescopic plug board automatically extends and engages with the insertion slot, thus facilitating the installation of the street lamp post.

[0013] Optionally, the core cutter is circumferentially divided into multiple unit cutters. One unit cutter corresponds to one pressure rod and one pre-pressure wire. A lifting groove is vertically formed on the installation cylinder. The unit cutter is slidably matched with the lifting groove. A downward pressure groove is formed downward at the bottom of the lifting groove. An insertion tip with a V-shaped bottom is arranged on the unit cutter and slides in the downward pressure groove. A ring groove communicating with all the downward pressure grooves is circumferentially formed on the outer side wall of the installation cylinder. A plurality of groups of correction parts are circumferentially arranged in the ring groove. The correction part includes two arc strips slidably arranged in the ring groove, and correction inclined surfaces are arranged on the opposite sides of the two arc strips. A correction compression spring is propped between the arc strips of two circumferentially adjacent correction parts. The propping surfaces of the two arc strips in the same group are located directly below the insertion tip in the corresponding downward pressure groove. The correction inclined surface is inclined downward along the direction close to the propping position of the two arc strips. A plurality of limit slots are formed on the correction inclined surface along its inclined direction.

[0014] By adopting the above technical solution, when there is a certain inclination in the hoisted lamp post, each pressure rod in the lamp post will successively contact the corresponding unit cutter. Each unit cutter descends successively. The first descending unit cutter drives the corresponding insertion tip to first insert between the corresponding two arc strips, resulting in the circumferential offset of the arc strips and correction compression springs of the remaining correction parts. This causes the later descending insertion tip to insert into the limit slot and not pass through between the corresponding two arc strips. The plug-in fit between the insertion tip and the limit slot also hinders the further descent of the lamp post. It is necessary to lift the lamp post upward again and adjust it to be perpendicular to the ground before the assembly between the mounting seat and the lamp post can be successfully achieved.

[0015] Optionally, a retaining ring for covering the ring groove is slidably sleeved outside the installation cylinder, and the retaining ring is arranged on any one of the unit cutters.

[0016] By adopting the above technical solution, the retaining ring covers the ring groove, reducing the possibility of structures such as arc strips and correction compression springs accidentally disengaging from the ring groove.

[0017] Optionally, an arc groove is circumferentially formed on the outer side wall of the installation cylinder. A reset end plate extending into the arc groove and slidably matched with it is arranged on any one of the arc strips. A reset compression spring is propped between the side of the reset end plate corresponding to the arc strip propping the correction compression spring and the end of the arc groove.

[0018] By adopting the above technical solution, when the assembly of the lamp post fails, the reset end plate can drive the corresponding arc strip to always reset to the same position under the action of the reset compression spring. This arc strip can also drive other arc strips and correction compression springs to reset to the set position for the subsequent re-attempt of installing the lamp post.

[0019] Optionally, the unit cutter includes a cutter base and an elastic blade. A wire-breaking inclined surface is arranged at a position directly below the elastic blade on the mounting seat.

[0020] By adopting the above technical solution, during the downward movement of the unit cutting knife, the elastic blade will press the pre-pressed wire tightly against the wire-breaking inclined plane, and it will undergo a small amount of deformation, and this small amount of deformation can ensure that the elastic blade cuts the pre-pressed wire.

[0021] In a second aspect, the present application provides an installation method for a street lamp pole installation structure, adopting the following technical solution:

[0022] An installation method for a street lamp pole installation structure includes the following steps:

[0023] S1. The worker rotates the wire reel to wind up the telescopic wire, thereby accommodating the telescopic plug plate in the telescopic groove. The telescopic compression spring is compressed, and then the ratchet pawl is rotated to engage with the ratchet wheel, and then the mounting seat is bolted to the ground.

[0024] S2. After the lamp pole is hoisted by a crane to be accurately docked with the mounting seat, the worker reverses the ratchet pawl through the inspection opening to disengage it from the ratchet wheel. The telescopic compression spring pushes the telescopic plug plate to extend and be inserted into the insertion groove in a plugging fit, and finally the inspection opening is closed.

[0025] By adopting the above technical solution, the worker rotates the wire reel to wind up each telescopic wire synchronously. Each telescopic plug plate is accommodated in the corresponding telescopic groove. The end of the telescopic plug plate cooperating with the telescopic groove squeezes the telescopic compression spring, and then the ratchet pawl is rotated to engage with the ratchet wheel. Then, the mounting seat is bolted to the planned installation position on the ground. Subsequently, the lamp pole is hoisted by a crane to be accurately docked with the mounting seat, and the worker then reverses the ratchet pawl through the inspection opening to disengage it from the ratchet wheel. The telescopic compression spring pushes the telescopic plug plate to extend and be inserted into the insertion groove in a plugging fit, thereby realizing the installation of the street lamp pole. Even if an unexpected situation occurs during the hoisting process, the worker can first bolt the mounting seat to the ground in advance, thus saving a lot of time and improving the installation efficiency.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The worker rotates the wire reel to wind up each telescopic wire synchronously. Each telescopic plug plate is accommodated in the corresponding telescopic groove. The end of the telescopic plug plate cooperating with the telescopic groove squeezes the telescopic compression spring, and then the ratchet pawl is rotated to engage with the ratchet wheel. Then, the mounting seat is bolted to the planned installation position on the ground. Subsequently, the lamp pole is hoisted by a crane to be accurately docked with the mounting seat, and the worker then reverses the ratchet pawl through the inspection opening to disengage it from the ratchet wheel. The telescopic compression spring pushes the telescopic plug plate to extend and be inserted into the insertion groove in a plugging fit, thereby realizing the installation of the street lamp pole. Even if an unexpected situation occurs during the hoisting process, the worker can first bolt the mounting seat to the ground in advance, thus saving a lot of time and improving the installation efficiency;

[0028] 2. Workers unwind the telescopic guy wire in advance to a proper length. When hoisting the lamp post, the pressure rod inside the lamp post will contact the ring knife and push it downward. In this way, the ring knife cooperates with the mounting base to cut the pre-pressed guy wire. After that, under the action of the telescopic compression spring, the telescopic plug board automatically extends and is inserted into the insertion slot in a plugging fit, thus facilitating the installation of the street lamp post.

[0029] 3. When the hoisted lamp post is inclined to a certain extent, each pressure rod inside the lamp post will successively contact the corresponding unit cutter. Each unit cutter descends successively. The unit cutter that descends first drives the corresponding insertion tip to first insert between the corresponding two arc strips, resulting in the circumferential offset of the arc strips and the correction compression springs of the remaining correction parts. This causes the insertion tip that descends later to be inserted into the limit slot and will not pass through between the corresponding two arc strips. The plugging fit between the insertion tip and the limit slot will also prevent the further descent of the lamp post. It is necessary to lift the lamp post upward again and adjust it to be perpendicular to the ground before the assembly between the mounting base and the lamp post can be successfully achieved.

Detailed Embodiment

[0036] The following is combined with the attached Figures 1-5Further detailed description of the present application is provided below.

[0037] Embodiment 1

[0038] An installation structure of a street lamp pole 1 is disclosed in an embodiment of the present application.

[0039] Referring to Figure 1 , the street lamp pole installation structure includes a mounting base 2 bolted to a planned position on the ground. A plurality of telescopic slots 201 are circumferentially and evenly formed on the mounting base 2. Each telescopic slot 201 is formed along the radial direction of the mounting base 2, and the top surface of the telescopic slot 201 extends to the top surface of the mounting base 2.

[0040] Referring to Figure 1 , Figure 2 and Figure 3 , a telescopic plug board 3 is slidably arranged in each telescopic slot 201. A plugging slot 101 that is plugged and matched with the telescopic plug board 3 is formed on the inner side wall at the bottom of the lamp pole 1. A maintenance opening (not shown in the figure) is reserved at a position near the bottom of the lamp pole 1.

[0041] A receiving hole 202 is vertically formed at the center position of the top of the mounting base 2. The receiving hole 202 communicates with each contraction slot. A telescopic compression spring 4 is propped between the end of the telescopic slot 201 communicating with the receiving hole 202 and the corresponding telescopic plug board 3.

[0042] A wire wheel 5 is rotatably mounted at a position of the mounting base 2 opposite to the bottom of the receiving hole 202. A plurality of telescopic stay wires 6 are wound around the wire wheel 5. One telescopic stay wire 6 corresponds to one telescopic plug board 3 and is tied to it.

[0043] Referring to Figure 1 , Figure 2 and Figure 3 , a ratchet wheel 7 is coaxially arranged at the bottom of the wire wheel 5. A pawl 8 is hinged on the side wall of the mounting base 2 opposite to the receiving hole 202. A limited rotation compression spring 21 is propped between the pawl 8 and the side wall of the receiving hole 202. The pawl 8 is used to engage with the ratchet wheel 7.

[0044] Referring to Figure 1 , Figure 2 and Figure 3 , an installation cylinder 9 is coaxially bolted to the top of the mounting base 2. A ring cutter is vertically slidably sleeved on the outer side wall of the installation cylinder 9. A pressing rod (not shown in the figure) for pushing the ring cutter to move downward is also welded on the inner wall of the lamp pole 1.

[0045] Pre-tensioning stay wires 11 are arranged upstream and downstream of the telescopic plug board 3. The pre-tensioning stay wires 11 pass through the telescopic slot 201 and are tied to a position on the top of the mounting base 2 relative to the lower side of the ring cutter.

[0046] Referring to Figure 1 , Figure 2 and Figure 3, before installation, workers need to pre-plan the installation positions of each street lamp pole 1 on the road and mark the installation angles of the corresponding mounting bases for each pole 1.

[0047] Refer to Figure 1 , Figure 2 and Figure 3 , the worker ties the pre-tensioned guy wire 11 to the top of the mounting base 2, so that the pre-tensioned guy wire 11 houses the telescopic plug plate 3 in the telescopic groove 201, and the telescopic plug plate 3 cooperates with the telescopic groove 201 to squeeze the telescopic compression spring 4.

[0048] After that, rotate the wire reel 5 to pre-release a certain length of the telescopic guy wire 6, then the limit rotation compression spring 21 pushes the pawl 8 to rotate until it engages with the ratchet 7, and then bolt the mounting base 2 to the pre-planned position on the ground.

[0049] Refer to Figure 1 , Figure 2 and Figure 3 , the worker operates the crane to hoist the lamp pole 1, and the bottom end of the lamp pole 1 is hoisted and sleeved on the mounting base 2. During the hoisting process, the pressure rod in the lamp pole 1 will contact the ring cutter and push it downward. When the lamp pole 1 is in close contact with the ground, the ring cutter stops moving and just cuts off the pre-tensioned guy wire 11.

[0050] At this time, the pulling effect of the pre-tensioned guy wire 11 on the telescopic plug plate 3 disappears, and the pre-released telescopic guy wire 6 allows the telescopic compression spring 4 to recover its deformation, thereby pushing the telescopic plug plate 3 into the insertion slot 101.

[0051] Refer to Figure 1 , Figure 2 and Figure 3 , when installing the street lamp pole 1 with the above structure, even if an unexpected situation occurs during the hoisting process and temporary suspension of work is required, the worker can pre-bolt the mounting base 2 to the ground. After the unexpected situation is resolved, only by hoisting the lamp pole 1 and sleeving it on the base can the installation of the lamp pole 1 be achieved, saving a lot of time and improving efficiency.

[0052] Refer to Figure 2 , the position of the lamp pole 1 relative to the insertion slot 101 is also circumferentially provided with a plurality of limit rotation grooves 102 that are inserted and matched with the end of the telescopic plug plate 3. Two circumferentially adjacent limit rotation grooves 102 are in close contact, and the cross-sections of the telescopic plug plate 3 and the limit rotation grooves 102 are both V-shaped.

[0053] The end of the telescopic plug plate 3 is inserted and matched with the limit rotation groove 102 to achieve circumferential limitation of the lamp pole 1, reducing the possibility of accidental rotation of the lamp pole 1 during its subsequent use after being installed in place.

[0054] Refer to Figure 1 , Figure 2 and Figure 3, when the crane hoists the lamp post 1, the lamp post 1 is not perpendicular to the ground and there is a small inclination. Therefore, after it is sleeved onto the mounting base 2 and the ring knife is triggered to cut off the pre-tensioned guy wire 11, part of the telescopic plug 3 may not be accurately inserted and matched with the insertion slot 101.

[0055] When the installation of the lamp post 1 fails, it cannot be reinstalled immediately. The mounting base 2 needs to be restored to its initial state, and the pre-tensioned guy wire 11 needs to be re-tied to the mounting base 2, which will inevitably consume a lot of time and affect the installation efficiency of the lamp post 1. Therefore, higher requirements are put forward for the verticality during the street lamp hoisting process.

[0056] Refer to Figure 2 , Figure 3 and Figure 4 , for this reason, the ring knife is circumferentially divided into multiple unit cutters 12, and one unit cutter 12 corresponds to one pressure rod and one pre-tensioned guy wire 11. The unit cutter 12 includes a tool holder 121 and an elastic blade 122 bolted to the tool holder 121. A wire-breaking inclined surface 20 is arranged at a position of the mounting base 2 directly below the elastic blade 122.

[0057] When the unit cutter 12 moves downward, its elastic blade 122 will press the pre-tensioned guy wire 11 against the wire-breaking inclined surface 20 and move a small distance along the wire-breaking inclined surface 20. The elastic blade 122 will undergo a small deformation, and the small distance of the elastic blade 122 pressing against the pre-tensioned guy wire 11 can ensure that the elastic blade 122 cuts off the pre-tensioned guy wire 11, enabling the telescopic plug 3 to be smoothly inserted into the insertion slot 101.

[0058] Refer to Figure 3 , Figure 4 and Figure 5 , a lifting groove 901 is vertically opened on the outer side wall of the installation cylinder 9, and the tool holder 121 is slidably matched with the lifting groove 901. A downward pressure groove 902 is opened at the bottom of the lifting groove 901, and a tip 13 with a V-shaped bottom is integrally formed at the bottom of the tool holder 121 and slides in the pressure groove 902.

[0059] A ring groove 903 communicating with all the pressure grooves 902 is also circumferentially opened on the outer side wall of the installation cylinder 9. A plurality of groups of calibration parts are circumferentially arranged in the ring groove 903. One tip 13 corresponds to one calibration part. The calibration part includes two slide bars sliding in the ring groove 903, and a calibration compression spring 16 is propped between the arc bars 14 of two circumferentially adjacent calibration parts. The propping position of the two arc bars 14 in the same group is located at the communication position between the corresponding pressure groove 902 and the ring groove 903.

[0060] Refer to Figure 3 , Figure 4 and Figure 5, on the opposite sides of the two arc strips 14 in the same group, correction inclined planes 15 are arranged. The correction inclined planes 15 are inclined downward along the direction close to the top support of the two arc strips 14, and a plurality of limiting slots 141 are formed in the correction inclined planes 15 along their inclined directions.

[0061] Refer to Figure 3 , Figure 4 and Figure 5 , when the hoisted lamp post 1 has a certain inclination, each pressure rod in the lamp post 1 will successively contact the corresponding unit cutter 12, and each unit cutter 12 will descend successively.

[0062] The unit cutter 12 that descends first drives the corresponding insertion tip 13 to first insert between the corresponding two arc strips 14, resulting in circumferential offsets of the arc strips 14 and the correction compression springs 16 of the remaining correction parts. This also makes the insertion tip 13 that descends later insert into the limiting slot 141 and will not pass through between the corresponding two arc strips 14.

[0063] Refer to Figure 3 , Figure 4 and Figure 5 , the insertion and cooperation between the insertion tip 13 and the limiting slot 141 will also prevent the further descent of the lamp post 1. Therefore, only when the lamp post 1 is hoisted vertically, all the pressure rods push all the unit cutters 12 to descend synchronously, and all the insertion tips 13 can pass through between the corresponding two arc strips 14, so as to ensure the smooth insertion and cooperation between all the telescopic insertion plates 3 and the insertion slots 101.

[0064] When the inclination of the lamp post 1 causes the hoisting to fail, the lamp post 1 must be lifted upward again and adjusted to be perpendicular to the ground before the one-time smooth assembly between the mounting base 2 and the lamp post 1 can be achieved.

[0065] Refer to Figure 3 , Figure 4 and Figure 5 , an arc groove 904 is circumferentially formed on the outer side wall of the mounting cylinder 9. A reset end plate 18 that extends into the arc groove 904 and is slidably engaged with it is integrally formed on any one of the arc strips 14. A reset compression spring 19 is braced between the side of the reset end plate 18 corresponding to the arc strip 14 that braces the correction compression spring 16 and the end of the arc groove 904.

[0066] Refer to Figure 3 , Figure 4 and Figure 5 , when the assembly of the lamp post 1 fails, the reset end plate 18 can drive the corresponding arc strip 14 to always reset to the same position under the action of the reset compression spring 19, and this arc strip 14 can also drive other arc strips 14 and the correction compression springs 16 to reset to the set positions for the subsequent re-attempt of installing the lamp post 1.

[0067] Refer to Figure 3 , Figure 4And Figure 5 A retaining ring 17 is sleeved outside the installation cylinder 9 in a sliding manner for covering the annular groove 903, and the retaining ring 17 is bolted to any unit cutter 12. The retaining ring 17 covers the annular groove 903, reducing the possibility of structures such as the arc strip 14 and the calibration compression spring 16 accidentally disengaging from the annular groove.

[0068] The implementation principle of Embodiment 1 is as follows: Before installation, workers need to pre-plan the installation positions of each street lamp pole 1 on the road and mark the installation angles of the installation bases corresponding to each pole 1.

[0069] The worker ties the pre-tensioned guy wire 11 to the top of the mounting base 2, so that the pre-tensioned guy wire 11 houses the telescopic plug 3 in the telescopic groove 201, and the telescopic plug 3 cooperates with the telescopic groove 201 to squeeze the telescopic compression spring 4.

[0070] After that, rotate the wire wheel 5 to pre-release a certain length of the telescopic guy wire 6, then the limited rotation compression spring 21 pushes the pawl 8 to rotate until it engages with the ratchet 7, and then bolt the mounting base 2 to the pre-planned position on the ground.

[0071] After that, the worker operates the crane to hoist the lamp pole 1, and the bottom end of the lamp pole 1 is hoisted and sleeved on the mounting base 2 in a sliding manner.

[0072] When the lamp pole 1 is perpendicular to the ground, all the pressure rods push all the unit cutters 12 to descend synchronously, and the unit cutters 12 drive the corresponding inserts 13 to insert between the corresponding two arc strips 14, and the arc strips 14 of adjacent two calibration parts cooperate to squeeze the calibration compression spring 16.

[0073] The elastic blade 122 presses the pre-tensioned guy wire 11 against the end inclined plane and displaces a small distance, so that the elastic blade 122 cuts off the pre-tensioned guy wire 11. Pre-releasing a certain length of the telescopic guy wire 6 enables the telescopic compression spring 4 to restore its deformation, thereby pushing the telescopic plug 3 to insert into the insertion slot 101, and further realizing the installation of the lamp pole 1.

[0074] When the lamp pole 1 is inclined during the hoisting process, each pressure rod in the lamp pole 1 will successively contact the corresponding unit cutter 12, and each unit cutter 12 will descend successively.

[0075] The unit cutter 12 that descends first drives the corresponding insert 13 to first insert between the corresponding two arc strips 14, resulting in the arc strips 14 and the calibration compression spring 16 of the remaining calibration parts all undergoing corresponding circumferential displacements. This also causes the insert 13 that descends later to insert into the limit slot 141, rather than passing through between the corresponding two arc strips 14. The insertion fit between the insert 13 and the limit slot 141 also hinders the continued descent of the lamp pole 1, resulting in the installation failure. It is necessary to lift the lamp pole 1 upward again and adjust it to be perpendicular to the ground before the assembly between the mounting base 2 and the lamp pole 1 can be realized again.

[0076] Example 2

[0077] The installation method of the street lamp pole installation structure disclosed in Example 2 of the present application includes the following steps:

[0078] S1. Before installation, workers need to pre-plan the installation positions of each street lamp pole 1 on the road and mark the installation angles of the corresponding mounting bases for each pole 1.

[0079] S2. Workers tie the pre-tensioned guy wire 11 to the top of the mounting seat 2, so that the pre-tensioned guy wire 11 houses the telescopic plug plate 3 in the telescopic groove 201, and the telescopic plug plate 3 cooperates with the telescopic groove 201 to squeeze the telescopic compression spring 4. Then rotate the wire wheel 5 to pre-release a certain length of the telescopic guy wire 6, and then the limit compression spring 21 pushes the pawl 8 to rotate until it engages with the ratchet wheel 7. Next, bolt the mounting seat 2 to the pre-planned position on the ground.

[0080] S3. Thereafter, workers operate the crane to hoist the pole 1, and the bottom end of the pole 1 is hoisted and sleeved on the mounting seat 2 in a sliding manner.

[0081] When the pole 1 is perpendicular to the ground, all the pressure rods push all the unit cutters 12 to descend synchronously, and the unit cutters 12 drive the corresponding inserts 13 to insert between the corresponding two arc strips 14, and the arc strips 14 of adjacent two calibration parts cooperate to squeeze the calibration compression spring 16.

[0082] The elastic blade 122 presses the pre-tensioned guy wire 11 against the inclined surface at the end and displaces a small distance, so that the elastic blade 122 cuts off the pre-tensioned guy wire 11. Pre-releasing a certain length of the telescopic guy wire 6 enables the telescopic compression spring 4 to recover its deformation, thereby pushing the telescopic plug plate 3 into the insertion slot 101, and further realizing the installation of the pole 1.

[0083] When the pole 1 is inclined during the hoisting process, each pressure rod in the pole 1 will sequentially contact the corresponding unit cutter 12, and each unit cutter 12 will descend successively.

[0084] The unit cutter 12 that descends first drives the corresponding insert 13 to first insert between the corresponding two arc strips 14, resulting in the circumferential offset of the arc strips 14 and the calibration compression spring 16 of the remaining calibration parts. This also makes the insert 13 that descends later insert into the limit slot 141, rather than passing through between the corresponding two arc strips 14. The insertion fit between the insert 13 and the limit slot 141 will also prevent the pole 1 from continuing to descend, resulting in the installation failure. It is necessary to lift the pole 1 upward again and adjust it to be perpendicular to the ground before the assembly between the mounting seat 2 and the pole 1 can be realized again.

[0085] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
