Description

Technical Field

[0001] The present invention belongs to the field of transmission line construction in power transmission and transformation projects, and particularly relates to a pole hoisting frame and a method for erecting a pole group thereof. Background Art

[0002] Most of the iron towers in UHV transmission line projects are erected using a pole with a size of 900mm×900mm and a length of 45 meters. Since this pole is relatively heavy, weighing up to 5 tons, its own erection is a difficult problem. Currently, there are two common methods. One is to use an A-frame pole and a pulley block for tipping; the other is to use a truck crane for erection. However, the vast majority of the iron towers in UHV transmission line projects are located in mountainous areas. Some terrains are inaccessible to truck cranes, and the A-frame pole cannot be tipped as a whole. Using the forward erection method poses a safety hazard. Due to the large span between the legs of UHV iron towers, the construction difficulty is great and the efficiency is low. Only the reverse erection method or a combination of partial tipping and reverse erection can be adopted.

[0003] Currently, there is no special equipment for hoisting the pole. It mainly relies on a crane or other lifting tools for erection. Due to the complex terrain in mountainous areas, it is not convenient to park other large equipment. Only manual erection of the pole can be carried out, which is not only time-consuming and laborious but also unsafe. Summary of the Invention

[0004] Aiming at the above problems existing in the current pole erection, the purpose of the present invention is to provide a pole hoisting frame and a method for erecting a pole group thereof.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] The pole hoisting frame of the present invention is divided into multiple sections and is carried by a base located at the bottom. Each section has main materials as a frame. An opening side is provided on the main materials of each section. A flip door is provided on the opening side of the first section located at the bottom, and a sealing door is installed on the opening sides of other sections; one side of the lower end of the first section is hinged to the base, and the other side of the lower end is connected to the base after tipping. One end of the flip door is connected to the first section, and the inner side is connected to the first section when the pole is hoisted after the first section is tipped. The pole to be placed is installed on the flip door and is placed into the erected hoisting frame through the flipping of the flip door; the upper and lower ends of each section starting from the second section are respectively connected to adjacent sections. A lifting lug with a pulley is installed inside the main materials of each section. A lifting rope is wound around the pulley. One end of the lifting rope is connected to a hook, and the other end is pulled by a winch. The winch lifts the installed pole upward through the lifting rope and the hook; a flipping turning pulley for flipping the flip door is installed on the main materials of any section above the first section.

[0007] Wherein: the base includes a U-shaped plate, a support ear for the turning shaft of the uprighting, a turning pulley of the base, a first fixed lifting ear, and a seal for the U-shaped plate. The seal for the U-shaped plate is installed at the open end of the U-shaped plate. The support ear for the turning shaft of the uprighting, the turning pulley of the base, and the first fixed lifting ear are respectively installed on the U-shaped plate. One side of the lower end of the first section is hinged to the support ear for the turning shaft of the uprighting, and the support ear for the turning shaft of the uprighting serves as the support point for rotation during the uprighting process of the first section. The other side of the lower end of the first section is fixedly connected to the first fixed lifting ear after uprighting; the other end of the lifting rope bypasses the turning pulley of the base and is connected to a winch.

[0008] Lifting lugs are respectively provided at the four corners of the U-shaped plate, and each lifting lug fixes the base through a base guy wire.

[0009] The flip door includes a flip door rotating shaft, a boom bracket, a bearing, an uprighting lifting lug, a turning lifting lug, and a machine body frame. One end of the machine body frame is provided with a flip door rotating shaft rotatably connected to the first section, and the other end is respectively provided with an uprighting lifting lug and a turning lifting lug; the boom bracket is installed on one side of the machine body frame facing the lifting frame, and a plurality of bearings are provided along the length direction of the boom bracket.

[0010] There are two mutually parallel boom brackets, and the distance between them is greater than the width of the boom to be placed. Both boom brackets are made of angle steel with their right-angle sides facing each other. A plurality of holes are opened on the vertical right-angle sides of each boom bracket, and a reinforcing plate is welded at the position corresponding to each hole on the outer surface of the vertical right-angle side. The cantilever shaft of the bearing passes through the hole and the reinforcing plate.

[0011] The end faces of the main materials of each section of the boom lifting frame are all "U"-shaped, and the opening of the "U"-shape is the opening side, and auxiliary materials are provided on the three sides of the "U"-shape.

[0012] The main materials and the auxiliary materials are all welded by angle steel. The auxiliary materials are inclined, and the inclination directions of the auxiliary materials in the odd-numbered sections are opposite to those in the even-numbered sections.

[0013] Bolt connecting plates for fixing the flip door or the sealing door are provided on both sides of the "U"-shaped opening of the main materials of each section except the first section; lifting frame guy wire lugs are provided on the outer sides of the four corners of the "U"-shape at the top of each section of the main materials.

[0014] V-shaped wheels for fixing each section of the boom and serving as a lifting track are installed inside the main materials of each section of the boom lifting frame.

[0015] An ear hole for connecting one end of the lifting rope is opened at the upper end of the hook, and a plurality of grab hooks are evenly distributed along the width direction on the inner surface of the lower end.

[0016] The upper end of the first section is provided with a top connecting plate of the first section for connecting with the second section. On one side of the lower end, there is a standing welding plate for hinging with the base. On the other side of the lower end, the main material is a perforated angle steel for fixedly connecting with the base after standing. On the outside of the perforated angle steel, there is a flap door rotating shaft support ear for hinging with the flap door.

[0017] The method for assembling the pole of the pole hoisting frame of the present invention is as follows:

[0018] First, fix the base, lay down the section to be erected, hinge one side of the lower end with the base, and hinge the other side of the lower end with the flap door. After turning the flap door to a set inclination angle, fix it. Place the pole inside the section, and pull the flap door through the standing wire rope to erect the section and the pole inside. Install the pole to be placed on the flap door, and use the winch to pull the hook through the lifting rope and the pulley hung on the lifting lug, so as to lift the erected pole. Pull the flap door towards the hoisting frame direction to make the pole to be placed fall below the lifted pole, lower the lifted pole and connect it, and then install the next section and the closing door of the next section on the connected pole. The erection of the section and the pole is carried out alternately. After the erection of the required poles is completed, disassemble the hoisting frame step by step. The specific steps are as follows:

[0019] Step A: First, place the base at the central position of the pole to be erected and fix it with the base guy wires at the four corners. Then connect and install the first section, the second section and the closing door of the second section and lie them flat on the base, and place two poles inside the installed first section and the second section. Hinge one side of the lower end of the first section with the base, then install one end of the flap door on the other side of the lower end of the first section, open the flap door at an angle of 50 degrees relative to the first section, and connect the other end of the flap door with the middle part of the second section with the standing wire rope. Use the winch to pull the flap door through the standing wire rope to erect the first section, the second section, the closing door of the second section and the flap door together with the two poles. Finally, connect the other side of the lower end of the first section and the base with bolts to complete the erection of the first section and the second section.

[0020] Step B: Fix the flap door on the first section, fix one end of the lifting rope on the hook, and the grab hook on the hook grabs the cross brace of the lower pole among the two poles placed in advance. The other end of the lifting rope passes through the pulley hung on the lifting lug and is pulled by the winch to lift and erect the two erected poles. Stop lifting when reaching the set position.

[0021] Step C: Install the pole to be placed on the tipping door, fix one end of the tipping rope to the other end of the tipping door, let the other end of the tipping rope pass through the tipping turning pulley for turning, and use a winch to tow and make the tipping door with the pole to be placed turn upright; after the pole to be placed sits at the center position of the base 1, unload the pole from the tipping door, then let the previously placed two sections of the pole fall onto the pole that enters later, and connect them with bolts;

[0022] Step D: Fix the tipping door on the first section, use the installed pole as a support, use a towing rope and a winch to lift the third section and the third-section closing door, and apply a drag rope to the third section and the third-section closing door to avoid collision; after lifting in place, install the third section on the second section, and finally install the third-section closing door;

[0023] Then install the next section of the pole according to Step B and Step C, and install the fourth section and the third-section closing door according to Step D, that is, the pole erection and the section erection are carried out alternately until the installation of the entire lifting frame is completed, and then tie the guy wires for each section respectively to stabilize the lifting frame;

[0024] After the installation of the entire lifting frame is completed, install the poles successively according to Step B and Step C until the pole erection is completed; each time the pole is lifted, the grab hook on the lifting hook grabs the transverse brace at the end face of the pole;

[0025] After the pole erection is completed, according to the installation steps of the lifting frame, disassemble the erected lifting frame from the erected pole in reverse order.

[0026] The advantages and positive effects of the present invention are:

[0027] 1. During the erection process of the present invention, only a towing winch is needed to cooperate with towing or lifting, without any other auxiliary equipment, the operation is simple, the efficiency is high, the labor force is saved, and many problems in the pole erection in mountainous areas with complex terrain are effectively solved.

[0054] The present invention will be further described in detail below with reference to the accompanying drawings.

[0055] The gin pole lifting frame of the present invention is divided into multiple sections and is carried by the base 1 located at the bottom. Each section has the main material 205 as the frame. An opening side is provided on the main material 205 of each section. Among them, a turning door 3 is provided on the opening side of the first section 2 located at the bottom. Sealing doors are installed on the opening sides of other sections. One side of the lower end of the first section 2 is hinged to the base 1, and the other side of the lower end is connected to the base 1 after erection. One end of the turning door 3 is connected to the first section, and the inner side is connected to the first section 2 when the gin pole is lifted after the first section is erected. The gin pole to be placed is installed on the turning door 3 and is placed into the erected lifting frame through the turning of the turning door 3. The upper and lower ends of each section starting from the second section are respectively connected to the adjacent sections. Lifting lugs 503 with pulleys are installed inside the main material 205 of each section. A lifting rope 13 is wound around the pulley. One end of the lifting rope 13 is connected to a hook 9, and the other end is pulled by a winch. The winch lifts the installed gin pole upward through the lifting rope 13 and the hook 9. A turning pulley 501 for turning the turning door 3 is installed on the main material 205 of any section above the first section.

[0056] The end faces of the main materials 205 of each section of the gin pole lifting frame of the present invention are all "U"-shaped. The opening of the "U"-shape is the opening side, and auxiliary materials 206 are provided on all three sides of the "U"-shape. The main material 205 and the auxiliary material 206 are both welded by angle steels. The auxiliary material 206 is inclined. The inclination directions of the auxiliary materials 206 of the sections with odd numbers are opposite to the inclination directions of the auxiliary materials 206 of the sections with even numbers. Bolt connecting plates 204 for fixing the turning door 3 or the sealing door are provided on both sides of the "U"-shape opening of the main material 205 of each section except the first section 2. Lifting frame guy lugs 505 are provided on the outer sides of the four corners of the "U"-shape at the top of each section of the main material 205.

[0057] Inside each main material 205 of each section of the gin pole lifting frame of the present invention, a V-shaped wheel 208 for fixing each section of the gin pole and serving as a lifting track is installed.

[0058] As Figure 1A 、 Figure 1B shown, the gin pole lifting frame of this embodiment has six sections, namely the first section 2, the second section 5, two third sections 7 and two fourth sections 10. That is, the fifth section is exactly the same as the third section 7, and the sixth section is exactly the same as the fourth section 10. In addition, the gin pole lifting frame of this embodiment further includes a base 1, a flip door 3, a second-section closing door 6 installed on the second section 5, a total of four third-section closing doors 8 respectively installed on the third to sixth sections, and two hooks 9. The gin pole lifting frame of this embodiment is applicable to the erection of gin poles with a standard section of a gin pole with a cross-section of 900 mm × 900 mm and a length of 3 m. The total height is 18 m. The erection of the lifting frame and the erection of the gin pole 4 are carried out alternately. During the erection process, only a traction winch is needed to cooperate with traction or lifting, and no other auxiliary equipment is required. The operation is simple, the efficiency is high, the labor force is saved, and many problems in the erection of gin poles in mountainous areas with complex terrain are effectively solved.

[0059] As Figure 1A 、 Figure 1B 、 Figure 2 、 Figure 3 and Figure 4 shown, the base 1 is used to carry the entire 900 gin pole lifting frame, and includes a U-shaped plate 101, a guy wire hanger 102, a tipping shaft support ear 103, a base directional pulley 104, a first-section fixed hanger 105 and a U-shaped plate seal 106. The U-shaped plate 101 serves as the body of the base 1, and other components are all welded or connected to it. The U-shaped opening is for facilitating the removal of the base 1 from the gin pole after the gin pole erection is completed. There are four guy wire hangers 102, which are respectively welded at the four corners of the U-shaped plate 101 and are used to tie the base guy wire 11 to fix the base 1. There are two pairs of tipping shaft support ears 103, which are respectively welded on both sides of the U-shaped plate 101 and are used to connect the tipping welding plate 201 of the first section 2 and serve as the rotation support points when the first section 2 is tipped. The base directional pulley 104 is a commercially available product, and the base directional pulley 104 is respectively welded on both sides of the U-shaped plate 101 and plays a steering role when lifting the gin pole 4. There is a pair of first-section fixed hangers 105, which are respectively welded on both sides of the U-shaped plate 101 and are used to restrain the first section 2. After the first section 2 is tipped, the first-section fixed hanger 105 and the perforated angle steel 202 of the first section 2 are threaded together with bolts to play a role in fixing the first section 2. The U-shaped plate seal 106 is a strip-shaped plate, and the U-shaped plate seal 106 is connected to the open end of the U-shaped plate 101 with bolts to improve the strength and overall stability of the U-shaped plate 101, so that the U-shaped plate 101 will not be deformed under the action of the guy wires at the four corners and under heavy pressure.

[0060] The first section 2 is welded with ∠100×10 angle steel as the main material 205 and ∠56×8 angle steel as the auxiliary material 206, and the end face is U-shaped, which is convenient for placing the lifting pole 4 and its own disassembly. A bolt connecting plate 204 with through holes is welded on the inner edge of the angle steel on the opening side for connecting the flap door 3. The directions of the auxiliary materials 206 on the three sides of the first section 2 are all higher on the right and lower on the left. On the two main material 205 angle steels at the bottom of the first section 2, a lifting welding plate 201 is welded respectively for connecting the lifting rotation shaft support ear 103, which serves as the rotation support point when the first section 2 is lifted. There are two through holes on the two main material angle steels at the U-shaped opening of the first section 2. These two main materials are perforated angle steels 202. After the first section 2 is lifted, the first section fixed lifting ear 105 and the perforated angle steel 202 of the first section 2 are threaded together with bolts to fix the first section 2. On the outer edges of the bottoms of the two perforated angle steels 202, flap door rotation shaft support ears 203 are welded respectively, and they are connected with the flap door rotation shaft 301 of the flap door 3 with bolts, so that the flap door 3 can be turned up with the bolt as the rotation shaft. A V-shaped wheel 208 is installed inside the U-shape at the top of the first section 2 to restrain the lifting pole 4 when the lifting pole 4 is lifted. The top connecting plate 207 of the first section is used to connect with the bottom connecting plate 502 of the second section.

[0061] The tilting door 3 includes a tilting door rotating shaft 301, a pole support bracket 302, a reinforcing plate 303, a bearing 304, a lifting lug 305, a tilting lug 306 and a body frame 307. The body frame 307 is welded by ∠100×10 angle steel. One end of the body frame 307 is provided with a tilting door rotating shaft 301 rotatably connected to the tilting door rotating shaft support ear 203 on the first section 2. The other end is respectively provided with a lifting lug 305 and a tilting lug 306. There are two tilting lugs 306, located on the left and right sides at the other end. There is one lifting lug 305, located in the middle of the two tilting lugs 306. The pole support bracket 302 is installed on one side of the body frame 307 facing the lifting frame. The pole support bracket 302 consists of two parallel members, and the distance between them is greater than the width of the pole to be placed (i.e., greater than 900 mm). Both of the two pole support brackets 302 are made of ∠100×10 angle steel, with the right-angle sides facing each other. Along the length direction of each pole support bracket 302, a plurality of bearings 304 are provided. A plurality of holes are opened on the right-angle sides of the pole support bracket 302 in the vertical direction for installing the bearings 304. The pole 4 can roll and be restricted on the pole support bracket 302. After the pole is placed on the pole support bracket 302 and tied up, the tilting rope 14 can be fixed on the tilting lug 306. The tilting rope 14 is pulled by a winch through the tilting turning pulley 501 of the second section 5 to tilt the tilting door 3 up. The height of the pole support bracket 302 is just such that the 900 pole can fall exactly to the center of the U-shaped opening of the base 1 after tilting. Untying the rope tying the 900 pole completes the tilting of one 900 pole. On the outer surface of the right-angle side of the pole support bracket 302 in the vertical direction, since the angle steel is only 10 mm thick and is not sufficient to support the cantilever shaft of the bearing 304, a reinforcing plate 303 is welded at the position corresponding to each hole. The cantilever shaft of the bearing 304 passes through the hole and the reinforcing plate 303. Strengthening the thickness with the reinforcing plate 303 allows the 900 pole to roll easily on the pole support bracket 302.

[0062] Such as Figure 5A , Figure 5B And Figure 6As shown in the figure, the second section 5 includes a turning pulley 501, a bottom connecting plate 502 of the second section, two lifting lugs 503, a top connecting plate 504 of the second section, a lifting frame guy lug 505, and a bolt connecting plate 204, a main material 205, an auxiliary material 206, and four V-shaped wheels 208. The welding direction of the auxiliary material 206 of the second section 5 is higher on the left and lower on the right, and the overall structure is similar to that of the first section 2. The bottom connecting plate 502 of the second section has the same structure as the top connecting plate 207 of the first section and is used to connect the first section 2 and the second section 5. The two lifting lugs 503 are welded on both sides of the U-shaped opening at the top of the second section 5 and are used to hang pulleys, so that the lifting rope 13 can pass through the base turning pulley 104 and then turn through the pulleys hung by the lifting lugs 503 and be fixed on the ear hole 901 of the hook 9. The grab hook 902 of the hook 9 grabs the top of the 900 gin pole, thereby realizing the lifting of the 900 gin pole. The top connecting plate 504 of the second section is used to connect the third section 7. The lifting frame guy lug 505 is welded on the four main materials 205 at the top of the second section 5 and is used to tie guy wires to stabilize the gin pole lifting frame.

[0063] The second section door 6 is formed by welding ∠56×8 angle steels and is used to block the second section 5. The second section door 6 includes a vertical angle steel 601 and multiple horizontal angle steels 602 welded in parallel on the vertical angle steel 601, and an inclined angle steel 603 is welded between adjacent two horizontal angle steels 602. Both ends of each horizontal angle steel 602 are fixedly connected to the bolt connecting plates 204 on both sides of the U-shaped opening of the second section 5.

[0064] As Figure 7 , Figure 8 shown, the structure of the third section 7 is basically the same as that of the second section 5, except that the bottom is the top connecting plate 504 of the second section, and the direction of the auxiliary material 206 is the same as that of the first section 2. The third section door 8 is formed by welding ∠56×8 angle steels and is used to block the third section 7.

[0065] As Figure 9 shown, the upper end of the hook 9 is provided with an ear hole 901 connected to one end of the lifting rope 13, and multiple grab hooks 902 are evenly distributed along the width direction on the inner surface of the lower end. The lifting rope 13 is fixed on the ear hole 901 of the hook 9, and the grab hooks 902 of the hook 9 grab the top of the 900 gin pole, and the lifting of the 900 gin pole is realized under the traction of the winch.

[0066] The structure of the fourth section 10 is almost the same as that of the third section 7, and the difference is only that the direction of the auxiliary material 206 is the same as that of the second section 5.

[0067] The gin pole erection method of the gin pole lifting frame of the present invention is as follows:

[0068] First, fix the base 1. Lay down the section to be erected. One side of the lower end is hinged to the base 1, and the other side of the lower end is hinged to the flap door 3. After rotating the flap door 3 to a set inclination angle, fix it. Place the gin pole inside the section. Pull the flap door 3 through the erection guy wire 12 to erect the section and the gin pole inside. Install the gin pole to be placed on the flap door 3. Use a winch to pull the hook 9 through the lifting rope 13 and the pulley hung on the lifting lug 503, so as to lift the erected gin pole. Pull the flap door 3 towards the lifting frame direction to make the gin pole to be placed fall below the lifted gin pole. Lower the lifted gin pole and make connections. Then install the next section and the closing door of the next section on the connected gin pole. The erection of the section and the gin pole is carried out alternately. After the erection of the required gin poles is completed, disassemble the lifting frame step by step. The specific steps are as follows:

[0069] Step A, as Figure 10 shown, first, place the base 1 at the central position of the gin pole to be erected, and fix it by driving the base guy wires 11 at the four corners. Then connect and install the first section 2, the second section 5 and the closing door 6 of the second section, and lie them flat on the base 1. Place two sections of gin poles inside the installed first section 2 and second section 5. Connect the erection rotating shaft support ear 103 and the erection welding plate 201 with bolts. Then install the flap door rotating shaft 301 of the flap door 3 on the flap door rotating shaft support ear 203 of the first section 2. Open the flap door 3 at an angle of 50 degrees relative to the first section 2. Connect the flap door lifting ear 306 with the middle part of the second section 5 with the flap-up rope 14. By using a winch to pull the erection guy wire 12 to the position of the erection lifting ear 305, the first section 2, the second section 5, the closing door 6 of the second section and the flap door 3 with two sections of gin poles can be erected together. Finally, connect the perforated angle steel 202 of the first section 2 and the first section fixed lifting ear 105 of the base 1 with bolts, and the erection of the first section 2 and the second section 5 is completed.

[0070] Step B, as Figure 11 shown, fix the flap door 3 on the first section 2. Fix one end of the lifting rope 13 on the ear hole 901 of the hook 9. The grab hook 902 on the hook 9 grabs the second cross brace from the bottom of the two sections of gin poles placed in advance. The other end of the lifting rope 13 passes through the pulley hung on the lifting lug 503 and the deflection of the base turning pulley 104, and the two sections of erected gin poles are pulled and lifted by the winch, and stop lifting when reaching a position 1.5 m higher than the 900 gin pole.

[0071] Step C, as Figure 12As shown in the figure, place the next section 900 of the gin pole to be inserted on the gin pole bracket 302 and tie it up. Fix one end of each of the two turning ropes 14 to the two turning lugs 306 respectively. The other ends of the two turning ropes 14 are turned by the turning and steering pulleys 501 and pulled by the winch to turn up the door 3 with the next section 900 of the gin pole to be inserted. After the next section 900 of the gin pole to be inserted is seated in the central position of the base 1, untie the ropes binding the 900 gin pole, and then let the two previously inserted sections of the gin pole fall onto the later inserted 900 gin pole and connect them with bolts.

[0072] Step D, as Figure 13 shown in the figure, fix the door 3 on the first section 2. Using the inserted gin pole as a support, lift the third section 7 and the third section door 8 by means of the base turning pulley 104, the towing rope 16 and the winch; that is, there are two towing ropes 16, each of which is wound around the gin pole 4. One end bypasses the two base turning pulleys 104 of the base 1 and is connected to the winch, and the other ends are respectively connected to the third section 7 and the third section door 8. In order to avoid collision, apply a drag rope 15 to the third section 7 and the third section door 8; after lifting in place, install the third section 7 on the second section 5, and finally install the third section door 8.

[0073] Then as Figure 12 shown in the figure, install the next section of the gin pole according to Step B and Step C, and then as Figure 13 shown in the figure, install the fourth section 10 and the third section door 8 according to Step D. Alternate in this way, after installing the fourth section 10, it is the third section 7 and the third section door 8, and then the fourth section 10 and the third section door 8 until the installation of the entire 900 gin pole lifting frame is completed. Then use the lifting frame guy wire lugs 505 on each section to tie the guy wires at the set positions to stabilize the 900 gin pole lifting frame. After the installation of the entire six-section 900 gin pole lifting frame is completed, as Figure 11 、 Figure 12 shown in the figure, successively install the 900 gin pole 4 according to Step B and Step C until the gin pole erection is completed. Each time the 900 gin pole is lifted, the grab hook 902 on the hook 9 should grasp the end cross brace of the 900 gin pole because the end cross brace of the 900 gin pole has a stronger anti-destruction ability than the auxiliary materials.

[0074] After the gin pole erection is completed, in reverse order according to the installation steps of the 900 gin pole lifting frame, disassemble the erected 900 gin pole lifting frame from the erected gin pole, and the lifting and erection of the gin pole are completed.

[0075] The working principle of the present invention is:

[0076] Determination of the stability solution for the 900 mast lifting frame: The four corners of the base 1 of the 900 mast lifting frame are equipped with guy lugs 102, and guy wires 11 can be installed to stabilize the base 1. Moreover, starting from the second section 5, there are four lifting frame guy lugs 505 at the upper end of each section. During application, the guy wire positions can be selected according to environmental conditions, making the 900 mast lifting frame more stable.

[0077] Determination of the self-erection solution for the 900 mast lifting frame: The first section 2 and the second section 5 form a triangle with the hinged door 3. With the hinged door 3 as the traction point and the erection pivot support ear 103 of the base 1 as the rotation point, the first section 2 and the second section 5 with two sections of the mast are erected. Then, using the lifting and installation of the mast as a support, the lifting and installation of the remaining sections of the 900 mast lifting frame are alternately completed. Moreover, each section of the 900 mast lifting frame is made into a U shape for easy installation and disassembly, and the corresponding doors of each section are connected to improve strength and stability.

[0078] Determination of the mast lifting solution: When the 900 mast lifting frame only has the first section 2 and the second section 5, due to the limited lifting height, the hook 9 should grasp the second cross brace from the bottom of the lower mast of the two pre-placed masts. The lifting rope 13 passes through the pulley hung on the lifting lug 503 and the turning of the base turning pulley 104, and the two erected masts are pulled and erected by a winch. Stop lifting when reaching a position about 1.5 m higher than the 900 mast. When the 900 mast lifting frame is installed to the third section 7, the pulley hung on the lifting lug 503 of the second section 5 should be changed to the third section 7. The grab hook 902 should grasp the top surface cross brace of the newly inserted 900 mast. The lifting rope 13 passes through the pulley hung on the lifting lug 503 of the third section 7 and the turning of the base turning pulley 104, and the mast is pulled and lifted by a winch. Stop lifting when the bottom surface of the mast reaches a position about 1.5 m higher than the 900 mast. As the masts are successively inserted, the lifting weight is constantly increasing, so the grab hook 902 should be changed to grasp the top surface cross brace of the newly inserted 900 mast.

[0079] Determination of the mast guiding solution: Each section of the 900 mast lifting frame has a cross section of 1300×1300 mm. When lifting the 900 mast, it is inevitable that the 900 mast will collide with the inner wall of the 900 mast lifting frame or get stuck. To prevent this from happening, two V-shaped wheels 208 are installed inside the U-shaped opening of the first section 2, and four V-shaped wheels 208 are installed inside the U-shaped openings of the second section 5, the third section 7, and the fourth section 10. The relative distance between these V-shaped wheels 208 is exactly larger than the cross section of the 900 mast, so that there will be no collision and jamming during the lifting process of the mast.
