Description

Technical Field

[0001] This application relates to the field of power transmission equipment, and in particular to an installation structure for a crossarm of a transmission tower. Background Technology

[0002] In the power transmission industry, towers and poles serve as the main supports for power lines and are ubiquitous in daily life. Towers are the most common type, their function being to prevent high-voltage lines from undergoing a short-range electrical shock and impacting people on the ground. (Reference) Figure 1 The tower includes a tower body 2, and crossarm bases 1 are provided on both sides of the tower body 2. High voltage lines are generally fixed evenly on the crossarm bases 1 on both sides of the tower body 2 at specified intervals. Therefore, as the main load-bearing component, the crossarm base 1 is required to have strong fixing strength and a relatively simple fixing connection with the tower body 2, so as to meet the strength requirements and facilitate installation.

[0003] Currently, when installing the crossarm base 1 onto the tower body 2, the usual practice is to first use an external tower crane to lift the crossarm base 1 to the set height, and then the external tower crane connects the crossarm base 1 to the tower body 2 to ensure that the crossarm base 1 is located in the set position on both sides of the tower body 2. However, it is difficult to accurately adjust the height of the crossarm base 1 using an external tower crane. Therefore, after hoisting the crossarm base 1 to a certain height, workers need to use traction ropes to pull the crossarm base 1 to adjust its specific installation position. Because the crossarm base 1 has a relatively heavy structure, it is difficult to install it successfully in one go. Therefore, workers need to use traction ropes to repeatedly pull the crossarm base 1 to adjust its precise position, which is labor-intensive and requires a lot of physical strength from the power workers. Utility Model Content

[0004] In order to reduce the labor intensity of workers and facilitate the installation and fixing of the tower body and the crossarm base, this application provides an installation structure for the crossarm of a steel tower.

[0005] The technical solution of the installation structure of the crossarm of the iron tower provided in this application is as follows: The installation structure of the iron tower crossarm includes an installation structure body, the installation structure body includes an adjustment component disposed on the side of the crossarm base facing the tower body, a guide installation shoe disposed on the side of the tower body, and a fixing member for fixing the position of the adjustment component on the guide installation shoe. The adjustment component is slidably engaged with the guide installation shoe, and a force-applying part is provided on the adjustment component for driving the adjustment component to slide on the guide installation shoe.

[0006] By adopting the above technical solution, the installation structure body serves to connect the crossarm base and the tower body. The adjustment component set on the side of the crossarm base facing the tower body plays the main connecting role. The guide mounting shoe set on the side of the tower body serves as the main installation component of the tower body. The guide mounting shoe is connected to the adjustment component through a sliding fit. It is a fixing component used to fix the position of the adjustment component on the guide mounting shoe, thus serving as the main component of the crossarm base and the tower body, providing lateral support and connection. The force-applying part is used to drive the position of the adjustment component on the guide mounting shoe, thereby achieving basic alignment of the crossarm base and the tower body, which facilitates installation.

[0007] Optionally, the adjustment assembly includes a first mounting base fixed to the crossarm base, the guide mounting shoe includes a base plate fixed to the tower body, a guide rail fixed to the side of the base plate opposite to the tower body, and a groove is provided on the side of the first mounting base opposite to the crossarm base for the guide rail to be inserted and slid.

[0008] By adopting the above technical solution, the first mounting base is fixedly connected to the crossarm base, and the base plate is fixedly connected to the tower body. A guide rail is fixedly connected to the side of the base plate away from the tower body and the first mounting base is provided with a sliding engagement for the guide rail on the side away from the crossarm base, thereby basically achieving the vertical alignment of the crossarm base and the tower body.

[0009] Optionally, the guide mounting shoe further includes an arc-shaped positioning protrusion fixed to the side of the guide rail away from the substrate. The width of the arc-shaped positioning protrusion is greater than the width of the guide rail, and the bottom of the slide groove is provided with a guide groove for the arc-shaped positioning protrusion to be inserted and slid.

[0010] By adopting the above technical solution, the width of the arc-shaped positioning protrusion is greater than the width of the guide rail, so that it will not slip out in the guide groove, ensuring the installation process of the crossarm base and the tower body.

[0011] Optionally, the force-applying part includes a gear rotatably connected to one end of the first mounting base, a rack fixed to one end of the base plate, and a force-applying rod fixed to one side of the gear for driving the gear to rotate, wherein the gear meshes with the rack.

[0012] By adopting the above technical solution, the gear rotatably connected to one end of the first mounting base provides a driving component for meshing transmission to finely adjust the distance, the rack fixed to one end of the base plate provides support for the gear to mesh and transmit, and the force rod fixed to one side of the gear drives the gear to rotate.

[0013] Optionally, the end of the force-applying rod away from the gear has a force-applying groove.

[0014] By adopting the above technical solution, a force-applying groove is provided at the end of the force-applying rod away from the gear. The force-applying groove can be connected to an external drive device to achieve rotational drive of the gear.

[0015] Optionally, the fastener includes a transverse fixing plate fixed to the tower body, a transverse fixing base fixed to the crossarm base, and a first pin passing through the transverse fixing plate and the transverse fixing base.

[0016] By adopting the above technical solution, the horizontal fixing plate and the horizontal fixing base are connected by the first pin, thereby ensuring the relative position of the horizontal fixing plate and the horizontal fixing base.

[0017] Optionally, the adjustment assembly further includes a second mounting base fixed to one side of the crossarm base. The first mounting base and the second mounting base are located on the upper and lower sides of the crossarm base, respectively. The guide mounting shoe further includes two parallel directional lugs fixed to the tower body. The adjustment assembly further includes a snap-fit ​​side plate fixed to the side of the second mounting base away from the crossarm base. A sliding space is formed between the two directional lugs for the snap-fit ​​side plate to be inserted and slid.

[0018] By adopting the above technical solution, a snap-fit ​​side plate is fixed to one side of the crossarm base. The first mounting base and the second mounting base are located on the upper and lower sides of the crossarm base, respectively, thereby providing a stable connection to the four corners of the crossarm base. The sliding space formed between the two parallel directional lugs is used for the embedded installation of the snap-fit ​​side plate.

[0019] Optionally, the two directional ear plates are fixedly connected with a snap-fit ​​assembly for preventing the second mounting base from sliding to a set position on the directional ear plate.

[0020] By adopting the above technical solution, the installed snap-fit ​​side plate is embedded between the two parallel directional ear plates and reaches the bottom of the snap-fit ​​assembly. The snap-fit ​​assembly is then used to fix the position of the snap-fit ​​side plate by the two parallel directional ear plates.

[0021] Optionally, the latching assembly includes a latching body fixed between the two directional lugs and a spring pin installed on the side of the latching body facing the crossarm base, wherein the second mounting base has a positioning groove on the side facing the directional lugs for the spring pin to be inserted.

[0022] By adopting the above technical solution, the snap-fit ​​body fixed to the top of the two directional lugs contains a spring pin facing the crossarm base. The spring pin can further limit the position of the two directional lugs and the snap-fit ​​side plate. The positioning groove is used to accommodate the spring pin, thereby achieving the above-mentioned effect.

[0023] Optionally, the fastener includes a second pin passing through the snap-fit ​​side plate and the directional ear plate.

[0024] By adopting the above technical solution, the second pin is used to fix the snap-fit ​​side plate and the directional ear plate for position alignment.

The guide mounting shoe 4 includes a base plate 41, which is fixedly connected to the tower body 2. A guide rail 42 is fixedly connected to the base plate 41 on the side of the base plate 41 away from the tower body 2. A groove 32 is provided on the first mounting base 31 on the side of the first mounting base 31 away from the crossarm base 1. The groove 32 allows the guide rail 42 to be inserted and slid.

[0041] Reference Figure 3 and Figure 5Specifically, the guide mounting shoe 4 also includes an arc-shaped positioning protrusion 43, which is fixed to the side of the guide rail 42 away from the base plate 41. The bottom of the slide groove 32 is provided with a guide groove 33, which allows the arc-shaped positioning protrusion 43 to be inserted and slide. The width of the arc-shaped positioning protrusion 43 is greater than the width of the guide rail 42, so that the arc-shaped positioning protrusion 43 will not fall out of the guide groove 33.

[0042] Reference Figure 3 The force-applying part 6 includes a gear 62, a rack 61, and a force-applying rod 622. The gear 62 is rotatably connected to one end of the first mounting base 31, the rack 61 is fixed to one end of the base plate 41, and the force-applying rod 622 is fixed to one side of the gear 62. When the guide rail 42 slides into the groove 32, the gear 62 meshes with the rack 61. The force-applying rod 622 can drive the gear 62 to rotate, thereby controlling the meshing position of the gear 62 and the rack 61.

[0050] refer to Figure 2 A lifting ring 11 is fixed at the center of mass of the crossarm base 1, so that when the external lifting equipment lifts the crossarm base 1 through the lifting ring 11, the basic position of the crossarm base 1 will not tilt after lifting.

[0051] The implementation principle of the installation structure of a crossarm of a steel tower in this application embodiment is as follows: the external lifting equipment lifts the crossarm base 1 to a designated position on one side of the tower body 2 by means of the lifting ring 11 while maintaining the designated installation state. The adjusting component 3 and the guide installation shoe 4 pre-position the crossarm base 1 and the tower body 2. After the pre-position is completed, the power operator uses tools to adjust the height of the crossarm base 1 relative to the two sides of the tower body 2 by means of the force application part 6. The horizontal fixing plate 51 and the horizontal fixing base 52 located at the bottom of the crossarm base 1 are connected. Similarly, the snap-fit ​​side plate 34 located at the top of the crossarm base 1 and the directional ear plate 44 are slidably connected. After the connection, the snap-fit ​​component 8 fixes the height position of the installation structure of the crossarm base 1. After the installation is completed, the relative position of the crossarm base 1 and the tower body 2 is fixed by means of the first pin 53 and the second pin 55.
