Description

Technical Field

[0001] The present application relates to the technical field of power transformation equipment, and in particular to an indirect disassembly and assembly insulating bucket pulley and a hanging method thereof. Background Art

[0002] When working with live wires or working near live wires, it is often necessary to transfer materials, tools and other objects up and down. In order to save effort and work smoothly and safely, it is often necessary to hang pulleys near live line towers and other equipment as load-bearing tools.

[0003] According to the potential of the operator, the live working method can be divided into ground potential working method, intermediate potential method and equipotential working method. Among them, the biggest feature of the equipotential working method is that the operator directly contacts the live equipment by wearing a full set of shielding clothing to work, so it can effectively complete emergency and major maintenance work. The bucket pulley is a commonly used live working tool in the equipotential working process. When dealing with broken strands of wires, wire adhesion, foreign matter in wires, and installing or replacing spacers and shock-proof hammers, it is necessary to enter the strong electric field through an insulating soft ladder and a bucket pulley to implement equipotential work. However, during the operation process, when using the bucket pulley to hang up the overhead wire, it is easy to fall off the hook of the insulating operating rod, resulting in high-altitude falling objects, especially for high-voltage transmission lines with an operating distance of more than 3m and 220kv or even 500kv. The high-altitude falling objects and tool damage caused by the bucket pulley hanging not only delay the progress of the maintenance work, increase the difficulty of the work, but also increase the safety hazards of ground workers. Summary of the invention

[0004] In view of this, the present application provides an indirect disassembly and assembly of an insulated heel pulley and a hanging method thereof, which are used to solve the technical problems in the prior art that the heel pulley has poor on-site adaptability, is prone to falling off, and has safety hazards.

[0010] Preferably, the distance between the connecting plate and the first movable rod assembly is smaller than the distance between the connecting plate and the second movable rod assembly. The distance between the second movable rod and the connecting plate is larger to form a larger opening, which is more convenient for cross arms or flat irons to enter and exit from the opening.

[0011] Preferably, the bottom end of the connecting plate is connected to the bottom plate by chamfering.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0038] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0039] Reference Figures 1 to 4 The indirect disassembly and assembly of the insulated heel pulley provided in the embodiment of the present application includes an insulated pulley body 10, a pulley assembly 20 arranged at the bottom of the pulley body 10, and also includes a linkage device, the linkage device includes a lifting ring assembly 30 located at the top of the pulley body 10, a movable rod assembly 40 arranged at the bottom of the lifting ring assembly 30 and passing through the pulley body 10 and movable up and down relative to the pulley body 10, and an elastic member 50 arranged between the movable rod assembly 40 and the pulley body 10, and the movable rod assembly 40 forms an opening 60 or closes the opening 60 when it slides up and down relative to the pulley body 10.

[0040] In this embodiment, when the heel pulley is hoisted, the eye assembly 30 is forced to pull the movable rod assembly 40 upward, so that an opening 60 is formed between the movable rod assembly 40 and the pulley body 10, so as to facilitate the insertion of the overhead wire or the cross arm 70 from the opening 60. After the overhead wire or the cross arm 70 is inserted, the eye assembly 30 is separated from the hoisting structure, and under the action of gravity and the elastic member 50, the movable rod assembly 40 and the eye assembly 30 slide downward, thereby closing the opening 60 to prevent the overhead wire or the cross arm 70 in the opening 60 from falling out of the opening 60.

[0041] The use of this pulley structure can effectively prevent wires from falling off and objects from falling from high altitudes, breaking through the limitations of the traditional "power outage" method of operation, greatly improving operating efficiency, and can be applied to AC lines and DC lines of other voltage levels, and has great promotion significance.

[0042] Specifically, in this embodiment, the pulley body 10 is made of insulating material, specifically glass fiber, so that the insulation effect is guaranteed, the structural strength is improved, and the pulley body is prevented from being too heavy. Of course, it can also be made of other materials with good strength, insulation effect and light weight. Of course, in this embodiment, the linkage device can also be made of glass fiber.

[0043] The trolley body 10 includes a top plate 11, a bottom plate 12, and a connecting plate 13 connected between the top plate 11 and the bottom plate 12. Preferably, the top plate 11, the bottom plate 12, and the connecting plate 13 are integrally formed of a plate having a certain thickness. Of course, the top plate 11, the bottom plate 12, and the connecting plate 13 can also be spliced ​​together.

[0044] In this embodiment, the movable rod assembly 40 is divided into two groups, including a first movable rod assembly 41 and a second movable rod assembly 42. The first movable rod assembly 41 and the second movable rod assembly 42 are respectively located on both sides of the connecting plate 13. The tops of the first movable rod assembly 41 and the second movable rod assembly 42 are fixed to the bottom of the lifting ring assembly 30, and move in conjunction with the lifting ring assembly 30, while the bottoms of the first movable rod assembly 41 and the second movable rod assembly 42 pass through the top plate 11 downward to contact the bottom plate 12, and the elastic member 50 is arranged between the first movable rod assembly 41 and the top plate 11. By providing two groups of movable rod assemblies 40, the relative movement between the linkage device and the pulley body 10 is smoother, and the stability of the entire pulley is also increased.

[0045] Specifically, the first movable rod assembly 41 includes two first movable rods 411 arranged in parallel, and the two first movable rods 411 are both sleeved with an elastic member 50. The elastic member 50 is a spring. There are two springs, and each first movable rod 411 assembly 41 is sleeved with a spring. The bottom of the two first movable rods 411 is provided with a first linkage block 412, and the first linkage block 412 contacts the bottom plate 12. The bottoms of the two first movable rods 411 are connected as a whole through the first linkage block 412, so that the linkage consistency of the two first movable rods 411 is better. There is a step (not numbered in the figure) in the middle of the first movable rod 411, and the bottom of the spring abuts against the step, which supports and fixes the spring, and the top of the spring abuts against the bottom of the top plate 11. The spring is forced to shrink under the clamping of the step and the top plate.

[0046] Of course, as an alternative, the first movable rod assembly 41 may also only have one first movable rod 411. When one first movable rod 411 is provided, the diameter of the first movable rod 411 needs to be increased accordingly, that is, it needs to be thicker, and the spring also needs to be thicker accordingly to meet the requirements of elasticity and strength.

[0047] As an alternative, in an application scenario with a higher load-bearing requirement, the first movable rod assembly 41 may also be provided with four first movable rods 411, and the four first movable rods 411 are arranged in two rows and two columns. Accordingly, there are also four elastic members 50. The width of the lifting ring 32, the top plate 11, the bottom plate 12, etc. is also increased accordingly to accommodate the installation of the four first movable rods 411.

[0048] In this embodiment, the lifting ring assembly 30 includes a connecting block 31 and a lifting ring 32 disposed on the connecting block 31. The connecting block 31 and the lifting ring 32 are integrally formed or assembled. Figure 1 In this embodiment, there is one lifting ring 32, which is located at one end of the connecting block 31. Specifically, the lifting ring 32 is located directly above the elastic member 50, so that when the elastic member 50 is subjected to force, it can be better deformed by force. In this embodiment, the length and width of the connecting block 31 match the length and width of the top plate 11 of the pulley body 10, so that the connecting block 31 can be better placed on the top plate 11. The tops of the two first movable rods 411 of the two first movable rod assemblies 41 pass through the connecting block 31 and are fixedly connected to the lifting ring 32. That is, the tops of the two first movable rods 411 are connected as a whole with the lifting ring 32 through the connecting block 31, and the bottoms are connected as a whole through the first linkage block 412, so that the movement consistency of the two first movable rods 411 is better. Of course, the spacing between the two first movable rods 411 can be adjusted according to the width of the connecting block 31.

[0049] In this embodiment, there is one lifting ring 32 which is connected to the top of the first movable rod assembly 41 , and the top of the second movable rod assembly 42 passes through the connecting block 31 and is fixed to the connecting block 31 .

[0050] Furthermore, in this embodiment, the connecting plate 13 is not centrally located between the top plate 11 and the bottom plate 12, and one end of the top plate 11 away from the connecting plate 13 is bent downward to form a vertical reinforcing plate 14. The reinforcing plate 14 is integrally formed with the top plate 11, so that the connection consistency is better. The top plate 11, the connecting plate 13, the bottom plate 12 and the reinforcing plate 14 are enclosed to form a C-shaped structure.

[0051] Furthermore, the second movable rod assembly 42 includes two second movable rods 421 arranged in parallel, and the bottom of the two second movable rods 421 is provided with a second linkage block 422, the second linkage block 422 contacts the bottom plate 12, and the tops of the two second movable rods 421 pass through the reinforcing plate 14, extend into the top of the connecting block 31, and are fixed to the connecting block 31. In this way, the tops and bottoms of the two second movable blocks 421 are respectively connected to the second linkage block 422 through the connecting block 31 as a whole, so that during hoisting, the linkage force can be better received.

[0052] Similarly, as an alternative, the second movable rod assembly 42 may also be provided with only one second movable rod 421. When one second movable rod 421 is provided, the diameter of the second movable rod 421 needs to be increased accordingly to meet the strength requirement.

[0053] As an alternative, in an application scenario with a higher load-bearing requirement, the second movable rod assembly 42 may also be provided with four second movable rods 421, and the four second movable rods 421 are arranged in two rows and two columns. Accordingly, there are also four elastic members 50. The width of the top plate 11, the reinforcing plate 14, the bottom plate 12, etc. is also increased accordingly to accommodate the installation of the four second movable rods 421.

[0054] Preferably, the portion of the first movable rod assembly 41 passing through the top plate 11 and the portion of the second movable rod assembly 42 passing through the top plate 11 may also be sleeved with a shock absorbing member (not shown in the figure), that is, a shock absorbing member is provided between the top plate 11 and the connecting block 31 of the lifting ring assembly 20 to prevent the connecting block 31 from hitting the top plate 11 when the lifting ring assembly 20 moves downward driven by the first movable rod assembly 41 and the second movable rod assembly 42. Specifically, the shock absorbing member may be sleeved on the first movable rod 411 and the second movable rod 412, or may be attached to the bottom of the connecting block 31 or the top of the top plate 11 and avoid the first movable rod 411 and the second movable rod 412.

[0055] In this embodiment, one end of the top plate 11 is bent downward to form a vertical reinforcing plate 14. A perforation (not shown in the figure) is provided in the reinforcing plate 14. The two second movable rods 421 move in the perforation in the reinforcing plate 14. The reinforcing plate 14 not only guides the two second movable rods 421, but also supports and stabilizes the two second movable rods 421, thereby enhancing the strength of the entire device. When the second movable rods 421 are lifted upward, the opening 60 formed is also the interval opening between the reinforcing plate 14 and the bottom plate 12. Therefore, the height of the reinforcing plate 14 also determines the size of the opening 60. In practical applications, the height of the reinforcing plate 14 is preferably half the height of the connecting plate 13. In this way, the size requirement of the opening 60 is met under normal circumstances, and the reinforcing plate 14 has a certain height, taking into account the requirements of support and strength.

[0056] In this embodiment, the connecting plate 13 is not centrally located between the first movable rod assembly 41 and the second movable rod assembly 42, but is arranged closer to the first movable rod assembly 41, that is, the distance between the connecting plate 13 and the first movable rod assembly 41 is smaller than the distance between the connecting plate 13 and the second movable rod assembly 42. Since a spring is arranged between the first movable rod assembly 41 and the top plate 11, the first movable rod assembly 41 drives the spring to extend and compress during the up and down movement, and the second movable rod assembly 42 forms an openable / closable opening 60 with the connecting plate 13, the bottom plate 12 and the top plate 11 during the up and down movement, therefore, the spacing between the second movable rod 421 and the connecting plate 13 is larger to form a larger opening 60, which is more convenient for cross arms or flat irons to enter and exit from the opening.

[0057] Preferably, in this embodiment, the connecting plate 13 is disposed at one third of the length of the top plate 11, that is, the distance between the connecting plate and one end of the top plate 11 is approximately one third of the length of the top plate 11, and the distance between the connecting plate and the other end of the top plate is approximately two thirds of the length of the top plate 11. The connecting plate 13 is disposed at this position to take into account both the strength of the force and the size and space of the opening 60.

[0058] Moreover, in this structure of the present embodiment, the existing conical guide wheel is omitted between the second movable rod assembly 42 and the connecting plate 13, so that the opening 60 between the second movable rod assembly 42 and the connecting plate 13 has a larger space and is more flexible, which can be combined with the actual situation of the operation site and can be placed more stably on the cross arm 70 or flat iron for on-site operation. Of course, when necessary in specific occasions, a conical guide wheel can also be installed. In short, since the second movable rod assembly 42 forms an openable / closable opening 60 during the up and down movement process, the operation of the opening 60 is more convenient, and the operator can also add components or structures at the opening 60 according to the actual needs of the site to facilitate on-site operations.

[0059] In this embodiment, the bottom end of the connecting plate 13 is transitionally connected to the bottom plate 12 via a chamfer 15. The setting of the chamfer 15 reduces stress concentration, strengthens the connection strength between the connecting plate 13 and the bottom plate 12, and also makes the connection smoother and more beautiful. Of course, a mounting structure adapted to the cross arm 70 or the flat iron can also be set on the inner side of the connecting plate 13 to facilitate the placement of the cross arm or the flat iron so that it is fixed more firmly.

[0060] Reference Figure 2 In this embodiment, the length of the first linkage block 412 and the second linkage block 422 matches the width of the bottom plate 12, and the width of the first linkage block 412 and the second linkage block 422 is slightly wider than the width of the first movable rod 411 and the second movable rod 421. In this way, the first linkage block 412 and the second linkage block 422 can not only play a good connection role, but also do not increase the weight of the entire pulley. Moreover, when the opening 60 is closed, the second linkage block 422 contacts the bottom plate 12, which can better close the opening 60.

[0061] Of course, in order to achieve a better sealing effect, a card slot can be provided on the bottom plate 12 corresponding to the first linkage block 412 and the second linkage block 422, and the size of the card slot matches the size of the first linkage block 412 and the second linkage block 422, that is, the first linkage block 412 and the second linkage block 422 can be better accommodated when the opening 60 is closed, and the first linkage block 412 and the second linkage block 422 can be moved out of the card slot when the movable rod assembly 40 is lifted. Of course, as an alternative, other structures that contact the bottom plate 12 can also be used at the bottom of the first movable rod assembly 41 and the second movable rod assembly 42.

[0062] Further, refer to Figure 3 In this embodiment, a mounting hole (not numbered in the figure) is provided on the bottom plate 12, and the mounting hole is located between the connecting plate 13 and the second movable rod assembly 42. The pulley assembly 20 is rotatably connected to the bottom of the bottom plate 12 through the rotating shaft 21 extending into the mounting hole. In this way, the pulley assembly 20 is centrally located below the connecting plate 13 and the second movable rod assembly 42, making the entire pulley more stable; moreover, the pulley assembly 20 can be driven by the rotating shaft 21 to rotate 360 ​​degrees, which is convenient for on-site operation needs.

[0063] Preferably, refer to Figure 5 In this embodiment, the pulley assembly 20 is an open / closed cover structure. Since the general working hoisting rope is a closed loop structure or is long, it is difficult to put the hoisting rope on the pulley using the existing locking pulley assembly 20. In this embodiment, the pulley assembly 20 can be opened to facilitate the installation of the rope, which greatly saves the time of wire installation.

[0064] Specifically, the pulley assembly 20 includes a mounting frame 22 located below the bottom plate 12 and rotatably connected to the rotating shaft 21, two side plates 23 pivotally connected to the two ends of the mounting frame 22 and capable of being relatively opened and closed, and a pulley 24 sandwiched between the two side plates 23. When installing the rope, open the side plate 23 on one side, put the rope directly on the pulley 24, and then close the opened side plate 23 again to lock it. This structure is simple to operate and highly efficient.

[0065] Specifically, refer to Figure 2 In this embodiment, the middle of the mounting frame 22 is raised and connected to the rotating shaft 21, and the surrounding parts are drooped into an arch shape. Such a structure ensures that the mounting frame 22 can be better installed with the rotating shaft 21, and also prevents the mounting frame 22 from interfering with the bottom plate 12 when rotating with the rotating shaft 21. Of course, the mounting frame 22 can also adopt other structures as long as it can ensure that the pulley 24 and the bottom plate 12 can be rotatably connected.

[0066] Furthermore, the two side plates 23 are pivotally connected to the mounting frame 22 via two pivot shafts. The two side plates 23 each include a side plate body 231 and a receiving space (not numbered in the figure) formed inside the side plate body 231. The size of the receiving space is slightly larger than the size of the two ends of the pulley 24. The pulleys 24 are respectively placed in the receiving grooves of the side plates 23. In this way, the installation of the pulley 24 is more stable and will not interfere with the rotation of the pulley 24.

[0067] Further, refer to Figure 4 In this embodiment, a connecting column 232 is provided on the inner side of the bottom of each side plate 23. The two connecting columns 232 are arranged opposite to each other and are located below the pulley 24. The two connecting columns 232 are locked by bolts (not shown in the figure), so that the pulley 24 is limited between the two side plates and will not fall off. When the bolts are unscrewed, the two connecting columns 232 connected to each other are unlocked, and one side plate 23 can be opened, the rope is put on, and then the side plate 23 is closed, and the bolts are tightened to lock the side plate 23. Such a structure makes the installation of the rope simple, saves time, and improves the working efficiency of the operator.

[0068] Of course, as an alternative, the opening and closing locking structure between the two side plates 23 is not limited to the locking structure using bolts in the present embodiment, and a detachable connection method such as a snap-on connection may also be used.

[0069] The above-mentioned insulating bucket pulley provided in the present embodiment has a simple structure. An elastic member 50 is arranged on the pulley, which mainly utilizes gravity and elastic force to form an opening for installing a cross arm or a flat iron, so that the installation of the cross arm or the flat iron is more reliable, avoiding the risk of falling objects from a high altitude, and ensuring the safety of ground workers; moreover, the pulley assembly 20 is openable, which is convenient for wiring, saves wiring time, and improves working efficiency.

[0070] This embodiment adopts the above-mentioned indirect disassembly and assembly of the insulating bucket pulley, and its hanging method includes the following steps:
