Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically relating to a partial reinforcement component for iron towers. Background Technology

[0002] Currently, after a steel tower is erected outdoors, in order to ensure its overall safety and reduce stress changes caused by external forces, it is often reinforced locally according to its actual condition. Reinforcing the support legs of the tower to counteract stress changes that cause deformation of the support legs is a common reinforcement method. However, most current reinforcement methods involve drilling holes in the tower, cutting iron plates of appropriate length, and connecting adjacent support legs. This method requires excessive manual intervention, drilling holes and cutting suitable connectors, making the manual operation complex and cumbersome, and difficult to adapt to the reinforcement of towers of different shapes. Moreover, this structurally destructive modification to the tower may directly cause changes in local or overall stress, potentially jeopardizing the overall safety of the tower. Utility Model Content

[0003] The purpose of this utility model is to provide a local reinforcement component for iron towers to solve the problems mentioned in the background art.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A partial reinforcement component for a steel tower includes reinforcing angle steels, wherein the number of reinforcing angle steels is the same as the number of support legs of the steel tower and they are connected and matched one-to-one, and a connecting mechanism is provided between two adjacent reinforcing angle steels.

[0006] The fixing rod is the intermediate connecting rod in the connecting mechanism. The fixing rod is cylindrical in shape and has a stepped cavity with a single-sided opening in the middle.

[0007] The telescopic rod assembly is an adjusting device in the connecting mechanism, and the telescopic rod assembly is located in the stepped cavity and extends outward;

[0008] Connecting lugs, which are connecting components in the connecting mechanism, are two in number and are respectively connected to the end of the telescopic rod assembly and the other end of the fixed rod. The connecting lugs are connected and matched to the reinforcing angle steel by bolts.

[0009] A switch is a device in the connecting mechanism used to lock the telescopic rod assembly. The switch is disposed on the telescopic rod assembly and located outside the stepped cavity.

[0010] The telescopic rod assembly consists of a sealing plug and a rod body. The sealing plug is slidably sealed within the stepped cavity. The rod body is concentrically connected to the sealing plug and slidably extends out of the stepped cavity. The other end of the rod body is connected to the connecting lug on the corresponding side.

[0011] The switch consists of a fixed valve head and an adjusting valve head. The fixed valve head is integrally formed with the rod body and has a disc-shaped structure concentric with the rod body. There are two liquid passages 180° apart between the telescopic rod and the fixed valve head. One of the liquid passages passes through the sealing plug and connects the space of the fixed valve head and the corresponding sealing plug away from the opening end of the stepped cavity. The other liquid passage passes through the side of the rod body and connects the remaining space of the stepped cavity with the fixed valve head.

[0012] The regulating valve head has an overall annular structure. The regulating valve head, rod body and fixed valve head are all rotatably and concentrically sealed. The regulating valve head and the fixed valve head are connected at one end with two symmetrical arc grooves that correspond to the two liquid paths respectively. The circumference of the arc grooves corresponds to an angle of less than 60°. The regulating valve head is also embedded with a connecting annular groove that connects the two arc groove liquid paths.

[0013] Both the portion of the regulating valve head offset from the arc groove and the lower side of the fixed valve head are provided with locking lugs.

[0014] The fixing rod consists of two cylinders with different diameters, and the outer wall thickness of the two cylinders is the same after the stepped cavity is opened in the fixing rod.

[0015] This application has at least the following advantages compared to the prior art:

[0016] By combining reinforced angle steel and connecting mechanisms, a frame support can be provided for the support foot area of ​​the iron tower, thereby protecting the overall stress changes of the iron tower. At the same time, the adjustment of the telescopic rod assembly can be conveniently and quickly adjusted by the switch, without much manual operation and tightening. After fixing, it has high stability and can prevent external personnel from interfering with the entire reinforcement component, ensuring the overall safety and stability of the equipment after installation.

[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-6 As shown, a partial reinforcement component for a steel tower includes reinforcing angle steel 1. The number of reinforcing angle steel 1 is the same as the number of support legs 2 of the steel tower and they are connected and matched one by one. A connecting mechanism is provided between two adjacent reinforcing angle steel 1.

[0027] Fixed rod 3 is the intermediate connecting rod 41 in the connecting mechanism. The fixed rod 3 has a cylindrical structure and a stepped cavity 31 with a single-sided opening in the middle.

[0028] The telescopic rod assembly is an adjusting device in the connecting mechanism. The telescopic rod assembly is located in the stepped cavity 31 and extends outward.

[0029] Connecting lug 32 is a connecting component in the connecting mechanism. There are two connecting lugs 32, which are respectively connected to the end of the telescopic rod assembly and the other end of the fixed rod 3. The connecting lugs 32 are connected and matched to the reinforcing angle steel 1 by bolts.

[0030] The switch is a device in the connecting mechanism used to lock the telescopic rod assembly. The switch is installed on the telescopic rod assembly and located outside the stepped cavity 31.

[0031] During reinforcement, one worker first adjusts the extension length of the telescopic boom assembly within the fixed rod 3 to initially match the positional spacing of the support legs 2 of the tower requiring reinforcement. Then, another worker places the reinforcing angle steel 1 onto the support leg 2 of the tower and connects the connecting lug 32 on the fixed rod 3 to the corresponding reinforcing angle steel 1 using bolts. Alternatively, the reinforcing angle steel 1 can be pre-connected to the connecting lug 32 on the fixed rod 3 before installation; the installation steps are not limited. The extension length of the telescopic boom assembly is then adjusted until the connecting lug 32 is sufficiently matched to the support leg 2 on the other side of the tower. The other side's reinforcing angle steel 1 is then attached to the support leg 2. Finally, the connecting lug 32 on the telescopic boom assembly is connected to the reinforcing angle steel 1 using bolts to complete the connection mechanism on one side. Similarly, the connections at other locations are made in the same manner and steps as described above. After completion, the telescopic rod assembly is fixed by a switch to prevent it from automatically extending or retracting. This allows the four connecting mechanisms, together with the four reinforcing angle steels 1, to form a frame connection with the support legs 2 of the tower. Since the rectangular dimensions of the connecting mechanisms are fixed after the telescopic rod assembly is fixed and they are connected to the support legs 2, when the support legs 2 of the tower experience outward stress deformation, the four connecting mechanisms, together with the reinforcing angle steels 1, can provide a fixing and stress-relief function, thereby improving the overall stability and safety of the tower. At the same time, this connection method avoids drilling and abutting operations on the support legs 2 of the tower, preventing changes in the overall stress of the tower caused by such operations. The operation is also more convenient and faster.

[0032] The telescopic rod assembly consists of a sealing plug 4 and a rod body 41. The sealing plug 4 is slidably sealed inside the stepped cavity 31. The rod body 41 is concentrically connected to the sealing plug 4 and extends out of the stepped cavity 31 in a slidably sealed manner. The other end of the rod body 41 is connected to the connecting lug 32 on the corresponding side.

[0033] The two chambers of the sealing plug 4 inside the stepped cavity 31 are completely filled with hydraulic oil. The hydraulic oil is antifreeze hydraulic oil to meet the needs of outdoor use. When the sealing plug 4 moves, it will push the rod 41 to move accordingly. With the adjustment and blocking of the hydraulic oil in the stepped cavity 31 by the switch, the position of the rod 41 can be fixed. Compared with the ordinary adjustment method of direct bolt friction abutment or thread, it avoids the problem of difficult disassembly of the equipment caused by rust in the outdoor environment, and also avoids the problem of unstable fixation after adjustment due to improper locking operation.

[0034] A corresponding dustproof corrugated cover can be fitted between the outer side of the rod 41 and the connecting lug 32 on the fixed rod 3 and the corresponding side to further provide dustproof and other protection.

[0035] The switch consists of a fixed valve head 5 and an adjusting valve head 6. The fixed valve head 5 is integrally formed with the rod body 41 and has a disc-shaped structure concentric with the rod body 41. There are two liquid passages 51 that are 180° apart between the telescopic rod and the fixed valve head 5. One of the liquid passages 51 passes through the sealing plug 4 and connects the space of the fixed valve head 5 and the corresponding sealing plug 4 away from the opening of the stepped cavity 31. The other liquid passage 51 passes through the side of the rod body 41 and connects the remaining space of the stepped cavity 31 with the fixed valve head 5.

[0036] With the two hydraulic passages 51 in place, when the regulating valve head 6 is connected to the fixed valve head 5, the two hydraulic passages 51 connect the two spaces in the stepped cavity 31. At this time, by pulling the telescopic rod 41, the hydraulic oil in the two spaces in the regulator can flow to each other to meet the adjustment needs of the entire telescopic rod assembly. After the adjustment is completed, the connection between the regulating valve head 6 and the fixed valve head 51 can be closed. At this time, the two hydraulic passages 51 form independent hydraulic passage spaces. Due to the negative pressure and liquid pressure, the entire telescopic rod assembly will not slide, thereby achieving the effect of fixing the entire telescopic rod assembly, improving the stability of the equipment after adjustment and fixing, and the fixing method is convenient and quick.

[0037] The regulating valve head 6 has an overall ring-shaped structure. The regulating valve head 6, rod body 41 and fixed valve head 5 are all rotatably and concentrically sealed. At the end where the regulating valve head 6 is connected to the fixed valve head 5, there are two symmetrical arc grooves 61 that correspond to the two liquid passages 51 respectively. The circumference of the arc grooves 61 corresponds to an angle of less than 60°. The regulating valve head 6 also has a connecting ring groove 62 embedded in it, which connects the two arc grooves 61 to the liquid passages 51.

[0038] In the silent state, the two arc grooves 61 of the regulating valve head 6 correspond to the openings of the two liquid passages 51 on the fixed valve head 5 respectively. At this time, the two liquid passages 51 form an interconnected liquid passage 51 pipeline through the two arc grooves 61 and the connecting ring groove 62 connecting the two arc grooves 61, which can meet the flow requirements of the liquid passage 51 during regulation.

[0039] When fixation is required, simply rotate the regulating valve head 6 so that the arc groove 61 is misaligned with the opening of the liquid passage 51. At this time, the liquid passage 51 becomes an independent liquid passage 51 space again, which makes it convenient and quick to cut off and connect the liquid passage 51 without requiring too much manual fixing or unfixing operation.

[0040] Both the portion of the regulating valve head 6 offset from the arc groove 61 and the lower side of the fixed valve head 5 are provided with locking lugs 63.

[0041] After the overall adjustment of the four connecting mechanisms is completed, in order to prevent the equipment from failing due to malicious operation by external personnel, when the regulating valve head 6 cuts off the liquid path 51 of the arc groove 61, the locking lug 63 on the regulating valve head 6 will be fixed to the locking lug 63 on the lower side of the valve head 5. The locking lug 63 has a locking hole. In this way, any device that can restrict the rotation of the regulating valve head 6, such as a copper lock or a bolt lock, can be hung to protect the regulating valve head 6 and prevent it from turning and causing the liquid path 51 to be connected, thus preventing the reinforcement of the device from failing.

[0042] The fixing rod 3 is composed of two cylinders with different diameters. After the stepped cavity 31 is opened in the fixing rod 3, the outer wall thickness of the two cylindrical parts is the same.

[0043] This can balance the overall volume of the space on both sides inside the stepped cavity 31, and increase the overall strength of the rod 41 by expanding the opening of the stepped cavity 31.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
