Description

Technical Field

[0001] The invention relates to the technical field of hangers, in particular to a pre-assembled power pole tower assembly structure and an assembly method. Background Art

[0002] Power poles and towers play a vital role in modern society. They are not only a key component of the power transmission system, but also play an important role in promoting regional economic development and environmental protection and energy conservation.

[0003] The main types of power poles and towers are angle steel towers and steel pipe poles. Both can achieve high-level power transmission, but both require temporary assembly during installation. For angle steel towers, their structure is mostly angle steel, and lifting and assembly are less difficult. For steel pipe poles, each section is a tubular structure, and special hoists are required for lifting. These hoists are connected to the pole body through connecting devices such as steel cables and traction belts. Since the diameter of the steel pipe pole gradually decreases from bottom to top, there is a difference in diameter at both ends of each section of the pole body. This requires adjusting the length of each connecting device during connection, which requires a large amount of operation. In addition, if the force applied by each connecting device is uneven in the lifting state, the pole body is also at risk of slipping off the hoist. Summary of the invention

[0021] As a further solution of the present invention: the holding assembly includes a lifting arm arranged horizontally and parallel to the side guide plate, the lifting arm is connected with a sliding connection part, and the sliding connection part is slidably connected with a guide groove arranged on the side guide plate;

[0022] The retaining assembly also includes a vertical support rod rotatably connected to the first abutment roller, a through hole is formed on the vertical support rod, and the lifting arm is slidably connected to the vertical support rod through the through hole.

[0023] As a further solution of the present invention: the engaging groove includes a horizontal groove body and a vertical groove body arranged on the side guide plate, the horizontal groove body and the vertical groove body are connected, and the engaging wheel can roll in the horizontal groove body and the vertical groove body.

[0024] As a further solution of the present invention: the follower slide is connected to the vertical support rod through a connecting kit, and the connecting kit includes:

[0025] A first rotating pin formed on the follower slide;

[0026] A second rotating pin formed at an end of the vertical support rod away from the first abutment roller;

[0027] The first rotating pin and the second rotating pin are connected via a hinged rod, and the hinged rod is arranged in an inclined manner;

[0030] When the engaging wheel moves to the upper end of the vertical trough body, the hinge rod abuts against the abutting wheel.

[0031] The method for assembling a power pole tower using the pre-assembled power pole tower assembly structure comprises the following steps:

[0032] Step 1: Connect the supporting beam to the traction equipment through the lifting holes;

[0033] Step 2: Connect one end of the traction belt to the supporting beam, then pass the traction belt around the power pole tower to be hoisted and assembled, and connect the other end of the traction belt to the other side of the supporting beam;

[0034] Step 3: Start the traction equipment to raise the supporting beam until the traction belt is tightened and the power pole tower to be assembled is lifted;

[0035] Step 4: Before the power pole tower to be assembled leaves the ground, the power pole tower's own gravity can pull the reset assembly downward through the traction belt, so that the holding assembly is actuated and the engaging wheel moves along the guiding direction of the engaging groove, so that the two No. 1 abutting rollers move closer to each other and the traction belt is tightened;

[0036] Step 5: As the engaging wheel continues to move, the No. 1 abutment roller can move away from the supporting beam, and at the same time, the two groups of No. 2 abutment rollers move away from each other, thereby further tightening the traction belt.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] By setting up multiple sets of tightening mechanisms, each tightening mechanism can adjust the state of the traction belt according to the magnitude of the force and the diameter of the power pole tower in the section, so that the traction belt can have a good fit between the sections of the power pole tower, thereby making the forces on the sections of the power pole tower balanced, improving the stability, and avoiding the deformation of the structure caused by the forces on both ends of the power pole tower;

[0039] By means of the arranged holding assembly, the engaging wheel and the side guide plate, when the follow-up slide plate is driven to move downward relative to the supporting cross beam by the gravity of the power pole tower itself, the engaging wheel can be driven by the hinged rod to move along the horizontal groove body, so that the two No. 1 abutting rollers move relatively close to each other, thereby bending and tightening the middle part of the traction belt, which can increase the contact area between the traction belt and the power pole tower, increase the friction between the two, and ensure the tightness of the fit, and on the other hand, the No. 1 abutting roller can increase the tension of the traction belt, so that the traction belt itself is constrained, thereby preventing the power pole tower from rolling in the traction belt during the process of hoisting the power pole tower, and improving the stability during assembly;

[0040] By setting the hinged rod and the transverse movement assembly, when the diameter of the power pole tower is small, the No. 1 abutment roller can move toward the power pole tower along the traction belt, and at the same time, the two groups of No. 2 abutment rollers move away from each other, and the traction belt is further pushed, so that the power pole tower can move toward the No. 1 abutment roller, that is, the No. 1 abutment roller can move relative to the power pole tower, so that the No. 1 abutment roller acts on the traction belt attached to the power pole tower, thereby ensuring the contact area between the traction belt and the power pole tower and the stability during lifting.

[0041] By setting up the rotary locking kit, on the one hand, the end of the traction belt can be connected conveniently and quickly, reducing the amount of operation and difficulty of the workers during operation; on the other hand, under the pulling of the traction belt, the protrusion can be kept misaligned with the insertion entrance, which can effectively prevent the insertion part and the convex ring from detaching during lifting, thereby improving the connection stability between the convex ring and the insertion part and the safety during the assembly of the power pole tower.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0054] It is preferred that the structure is used in tubular power poles, such as steel pipe poles.

[0055] See also Figure 1 to Figure 9 In the embodiment of the present invention, the pre-assembled power pole tower assembly structure includes: a supporting beam 1 and a tightening mechanism.

[0056] The supporting crossbeam 1 is provided with a plurality of hanging holes 2 at equal intervals;

[0057] The tightening mechanism is provided with multiple groups and distributed along the length direction of the supporting crossbeam 1. Since the supporting crossbeam 1 is provided with multiple groups of tightening mechanisms, each tightening mechanism can adjust the state of the traction belt 15 according to the magnitude of the force and the diameter of the power pole tower in the section, so that the traction belt 15 can have a good fit with each section of the power pole tower, thereby making the force of each section of the power pole tower balanced, improving the stability, and avoiding the deformation of the power pole tower itself due to the force on both ends;

[0058] The tightening mechanism includes: a No. 1 abutting roller 6 and a No. 2 abutting roller 14, a traction belt 15, a reset assembly, a holding assembly, a side guide plate 10 and a transverse movement assembly, so that when the follow-up slide plate 3 is driven by the gravity of the power pole tower to move downward relative to the supporting crossbeam 1, the engaging wheel 7 can be driven by the hinge rod 4 to move along the horizontal groove 1002, so that the two No. 1 abutting rollers 6 move relatively close to each other, thereby bending and tightening the middle part of the traction belt 15, which can increase the contact area between the traction belt 15 and the power pole tower, increase the friction between the two, and ensure the tightness of the fit. On the other hand, the No. 1 abutting roller 6 can increase the tension of the traction belt 15, so that the traction belt 15 itself is constrained, thereby preventing the power pole tower from rolling in the traction belt 15 during the process of lifting the power pole tower, and improving the stability during assembly, as follows:

[0059] Two sets of the first abutment roller 6 and the second abutment roller 14 are respectively provided and located on both sides of the supporting beam 1;

[0060] The traction belt 15 is connected to the supporting beam 1, and the first abutment roller 6 and the second abutment roller 14 can pull the traction belt 15 in the opposite direction;

[0061] The reset assembly is connected to the end of the traction belt 15, and the reset assembly includes a hysteresis groove 101 and a connecting plate 102 arranged on the supporting crossbeam 1, a follower slide 3 is slidably installed in the hysteresis groove 101, and the follower slide 3 is slidably connected to a vertical shaft 18 arranged on the connecting plate 102, and a column spring 19 is sleeved on the vertical shaft 18, one end of the column spring 19 is connected to the connecting plate 102, and the other end is connected to the follower slide 3;

[0062] The follower slide plate 3 is connected to the traction belt 15 via a rotational condensation kit;

[0063] The rotary condensation kit includes a connecting frame 16 detachably connected to the follower slide 3, a convex ring 17 is provided inside the connecting frame 16, and an insertion port 1701 inclined upward is formed on the convex ring 17;

[0064] The rotational condensation kit also includes an insert connected to the end of the traction belt 15, and a protrusion 1501 is provided at the end of the insert, wherein the width of the protrusion 1501 is the same as the width of the insertion port 1701, and the end of the protrusion 1501 is an arc structure, and the radius of the arc structure is the same as the inner diameter of the convex ring 17.

[0065] In the initial state, due to the support of the cylindrical spring 19, the follower slide 3 is located at the upper end of the retardation groove 101. At this time, since the width of the protrusion 1501 is the same as the width of the insertion port 1701, the protrusion 1501 on the insertion piece at one end of the traction belt 15 can be aligned with the insertion port 1701 and the protrusion 1501 can be inserted into the convex ring 17. Since the end of the protrusion 1501 is an arc structure, the radius of the arc structure is the same as the inner diameter of the convex ring 17, so that after the protrusion 1501 is inserted into the convex ring 17, the protrusion 1501 can be aligned with the insertion port 1701. 01 is misaligned, so that the protrusion 1501 can be restricted in the convex ring 17, and one end of the traction belt 15 is locked, and then the traction belt 15 is passed around the lower part of the power pole tower to be hoisted and assembled, and finally the protrusion 1501 at the other end of the traction belt 15 is restricted in the convex ring 17 in the same direction, so that the two ends of the traction belt 15 are fixed, so that when lifting, the power pole tower to be assembled can be lifted by supporting the cross beam 1 and the traction belt 15. Based on the above setting, the connection of the two ends of the traction belt 15 can be more convenient, thereby reducing the operation amount and difficulty of the staff during operation.

[0066] It should be noted that, since the insertion port 1701 is in an inclined upward state, and the connection between the traction belt 15 and the insertion part is in the middle of the arc structure on both sides, the traction belt 15 can be straightened under the traction of the power pole tower, and actively drive the insertion part to rotate, so that the protrusion 1501 remains misaligned with the insertion port 1701, so that the protrusion 1501 cannot slide out of the insertion port 1701 during the lifting of the power pole tower, thereby improving the connection stability between the convex ring 17 and the insertion part, and improving the safety of the power pole tower during assembly.

[0067] Furthermore, the side of the No. 1 abutment roller 6 and the No. 2 abutment roller 14 away from the hanging hole 2 is the outer side, and the side of the No. 1 abutment roller 6 and the No. 2 abutment roller 14 facing the hanging hole 2 is the inner side. During the installation of the traction belt 15, the traction belt 15 should be placed on the outer side of the No. 1 abutment roller 6 and the inner side of the No. 2 abutment roller 14.

[0068] Through the above arrangement, on the one hand, the end of the traction belt 15 can be portable and quickly connected, reducing the operation workload and difficulty of the staff during operation; on the other hand, under the pulling of the traction belt 15, the protrusion 1501 can be kept misaligned with the insertion port 1701, which can effectively prevent the insertion part and the convex ring 17 from detaching during lifting, thereby improving the connection stability between the convex ring 17 and the insertion part and the safety during the assembly of the power pole tower.

[0069] See also Figure 5~Figure 6 The holding assembly is connected to the reset assembly and the first abutting roller 6, and an engaging wheel 7 is rotatably mounted on the holding assembly;

[0070] The holding assembly includes a lifting arm 8 arranged horizontally and parallel to the side guide plate 10, the lifting arm 8 is connected with a sliding connection part 9, and the sliding connection part 9 is slidably connected with a guide groove 1001 arranged on the side guide plate 10;

[0071] The holding assembly further comprises a vertical support rod 5 rotatably connected to the first abutment roller 6, a through hole 502 is formed on the vertical support rod 5, and the lifting arm 8 is slidably connected to the vertical support rod 5 through the through hole 502. Since the guide groove 1001 and the lifting arm 8 are in a vertical state, when the vertical support rod 5 moves on the lifting arm 8, the lifting arm 8 can also slide in the length direction of the guide groove 1001, so that the vertical support rod 5 has the effect of being guided in two vertical directions on the plane, so that the vertical support rod 5 can always maintain a vertical direction;

[0072] The side guide plate 10 is arranged on the supporting cross beam 1, and an engaging groove is formed on the side guide plate 10. When the reset assembly is actuated, the engaging groove cooperates with the engaging wheel 7, so that the first abutting roller 6 can perform horizontal and vertical movements in sequence;

[0073] The engaging groove includes a horizontal groove body 1002 and a vertical groove body 1003 provided on the side guide plate 10 . The horizontal groove body 1002 and the vertical groove body 1003 are connected. The engaging wheel 7 can roll in the horizontal groove body 1002 and the vertical groove body 1003 .

[0074] It should be supplemented that the follower slide 3 is connected to the vertical support rod 5 via a connection kit, and the connection kit includes:

[0075] A first rotating pin 301 disposed on the follower slide 3 and a second rotating pin 501 disposed at an end of the vertical support rod 5 away from the first abutting roller 6;

[0076] The first rotating pin 301 is connected to the second rotating pin 501 via a hinge rod 4 . The hinge rod 4 is tilted. The second rotating pin 501 is coaxially arranged with the engaging wheel 7 .

[0077] In the initial state, the follow-up slide 3 is at the upper end of the retardation groove 101, and the upper end of the hinged rod 4 has a tendency to be pulled upward. Under this tendency, the engaging wheel 7 will be at one end of the horizontal groove 1002 away from the vertical groove 1003. When the connection of the traction belt 15 is completed and the supporting beam 1 is driven upward through the lifting hole 2, the traction belt 15 will gradually tighten, and in the process of the power tower leaving the ground, the follow-up slide 3 will move downward relative to the supporting beam 1. At this time, the supporting beam 1 will cause the upper end of the hinged rod 4 to move downward, and the hinged rod 4 is in the initial state. In the inclined state, when the upper end of the hinged rod 4 moves downward, its other end can drive the engaging wheel 7 to move along the horizontal groove 1002. At this time, the height of the lifting arm 8 relative to the supporting beam 1 will remain constant, and the two vertical support rods 5 will move relative to each other along the length direction of the lifting arm 8. At this time, the two No. 1 abutment rollers 6 will also move relative to each other and act on the traction belt 15, so that the middle part of the traction belt 15 is tightened, and the traction belt 15 can have a larger contact area with the power pole tower, thereby increasing the friction between the two, so as to achieve the effect of increasing the tightness of the connection between the two.

[0078] It is worth noting that when the middle part of the traction belt 15 is tightened, the traction belt 15 will bend. At this time, the traction belt 15 can not only obtain a larger contact area with the power pole tower to improve the restraint effect, but also the bending of the traction belt 15 can increase its own tension and have a tendency to make the power pole tower move toward the supporting beam 1. At this time, when the diameter of the power pole tower is large, the No. 1 abutment roller 6 can act on the traction belt 15 that is attached to the power pole tower, so that the power pole tower is more stable when it is lifted, preventing the power pole tower from rolling on the traction belt 15.

[0079] It is also worth noting that the power pole tower acts on the follow-up slide plate 3 through its own gravity, causing the No. 1 abutment roller 6 to act on the traction belt 15. At the same time, the power pole tower's own gravity also acts on the traction belt 15 to make it straight. At this time, the traction belt 15 has a force that reacts on the No. 1 abutment roller 6, and the force on the No. 1 abutment roller 6 is balanced, and has a tendency to tighten the traction belt 15.

[0080] Through the above arrangement, when the follow-up slide plate 3 is driven by the gravity of the power pole tower to move downward relative to the supporting beam 1, the engaging wheel 7 can be driven by the hinge rod 4 to move along the horizontal groove 1002, so that the two No. 1 abutment rollers 6 move relatively close to each other, thereby bending and tightening the middle part of the traction belt 15, which can increase the contact area between the traction belt 15 and the power pole tower on the one hand, increase the friction between the two, and ensure the tightness of the fit. On the other hand, the No. 1 abutment roller 6 can increase the tension of the traction belt 15, so that the traction belt 15 itself is constrained, thereby preventing the power pole tower from rolling in the traction belt 15 during the process of lifting the power pole tower, thereby improving the stability during assembly.

[0081] See also Figure 7~Figure 8 The transverse movement assembly is installed on the supporting beam 1 and connected to the second abutment roller 14. The transverse movement assembly can drive the second abutment roller 14 to move horizontally when the first abutment roller 6 moves vertically;

[0082] The transverse movement assembly includes a bracket 11 mounted on the supporting beam 1, a slide groove 1101 is formed on the bracket 11, a sliding member 12 is slidably mounted in the slide groove 1101, one side of the sliding member 12 is rotatably connected to the second abutment roller 14, and the other side is rotatably mounted with an abutment wheel 13;

[0083] When the engaging wheel 7 moves to the upper end of the vertical slot 1003 , the hinge rod 4 abuts against the abutting wheel 13 .

[0084] From the structural perspective of the steel pipe pole, its diameter gradually decreases from the bottom to the top. At the same time, in order to ensure the structural strength and reduce the manufacturing cost, the diameter of each section is reduced successively, while the weight is not much different. That is, when lifting a power pole tower with a thinner diameter, only relying on the two No. 1 abutment rollers 6 to move closer to each other to tighten the traction belt 15 cannot restrain the power pole tower well. The main reason is that there is still a section of stretched traction belt 15 at the lower part of the No. 1 abutment roller 6, which enables the power pole tower to drive this part of the traction belt 15 to shake relative to the supporting beam 1, thereby increasing the instability.

[0085] In the present application, when lifting a power pole with a smaller diameter, the follower slide 3 can drive the engaging wheel 7 to move to the end of the horizontal trough 1002 through the articulated rod 4, and then make the engaging wheel 7 move downward along the vertical trough 1003. During this process, the engaging wheel 7 moves vertically downward along the vertical trough 1003, and the follower slide 3 also moves downward, so that the articulated rod 4 can move downward at a predetermined inclination angle. At this time, the side of the articulated rod 4 can form a matching relationship with the abutment wheel 13, so that the abutment wheel 13 can drive the sliding member 12 to move away from the supporting beam 1, and make the two No. 2 abutment rollers 14 move away from each other, that is, when the No. 1 abutment roller 6 moves downward, the two No. 2 abutment rollers 14 can move away from each other, so that the middle part of the traction belt 15 is further bent and tightened, and the power pole tower is further moved toward the supporting beam 1. At this time, the No. 1 abutment roller 6 can act on the traction belt 15 attached to the vicinity of the power pole tower again, so that the restraining force of the cable pole tower increases.

[0086] It should be emphasized that when the engaging wheel 7 moves along the vertical trough 1003, the No. 1 abutment roller 6 has the effect of synchronization with the power pole tower, that is, the movement states of the two are consistent, and by using the two No. 2 abutment rollers 14, the middle part of the traction belt 15 can be pushed, so that when the length of the traction belt 15 is constant, its lower end can move upward, so that the traction belt 15 can drive the power pole tower to move toward the supporting beam 1, and the No. 1 abutment roller 6 acts on the traction belt 15 that is close to the power pole tower.

[0087] Through the above arrangement, when the diameter of the power tower is small, the No. 1 abutment roller 6 can move toward the power tower along the traction belt 15, and at the same time, the two groups of No. 2 abutment rollers 14 move away from each other, and further push the traction belt 15, so that the power tower can move toward the No. 1 abutment roller 6, that is, the No. 1 abutment roller 6 can move relative to the power tower, so that the No. 1 abutment roller 6 acts on the traction belt 15 that is close to the power tower, thereby ensuring the contact area between the traction belt 15 and the power tower and the stability during lifting.

[0088] By extension, since multiple sets of tightening mechanisms are arranged on the supporting crossbeam 1, each tightening mechanism can adjust the state of the traction belt 15 according to the magnitude of the force and the diameter of the power pole tower section, so that the traction belt 15 can have a good fit between the sections of the power pole tower, thereby making the forces on the sections of the power pole tower balanced, improving the stability, and avoiding deformation of the structure of the power pole tower caused by the forces on both ends of the power pole tower.

[0089] As an embodiment of the present invention, a method for assembling a power pole tower using the pre-assembled power pole tower assembly structure is also proposed, comprising the following steps:

[0090] Step 1: Connect the support beam 1 to the traction equipment through the lifting hole 2;

[0091] Step 2: Connect one end of the traction belt 15 to the supporting beam 1, then pass the traction belt 15 around the power pole tower to be hoisted and assembled, and connect the other end of the traction belt 15 to the other side of the supporting beam 1;
