Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for the construction and installation of power transmission towers, and more specifically to a device for the construction and installation of power transmission towers. Background Technology
[0002] Transmission line towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are spatial truss structures, with the main members composed of single equilateral angle steel or combined angle steel. The materials generally used are Q235 (A3F) and Q345 (16Mn). The connections between the members are made of coarse bolts, which are connected by shear force. The entire tower is composed of angle steel, connecting steel plates, and bolts. Some components, such as the tower feet, are made by welding several steel plates into a single assembly. Therefore, hot-dip galvanizing for corrosion protection, transportation, and construction and erection are extremely convenient. For power towers with a height of less than 60m, foot spikes are installed on one of the main members of the tower to facilitate construction workers climbing the tower. Chinese Patent (CN222244575U) discloses "A Power Tower Construction and Installation Device". This application uses a drive mechanism combined with a tightening mechanism, an adjustment mechanism, and a positioning mechanism to form a new structure. The components in the adjustment end are activated and adjusted, and the components in the positioning end are connected by a snap-fit mechanism. This makes the locking end easy to disassemble and assemble, and the components in the locking end can be replaced according to the bolt type, thus improving the applicability. In addition, the components in the drive end are activated and driven to manually tighten the bolts, which improves efficiency.
[0003] In this prior art, the use of the device still has defects. For example, the locking rod head used to tighten the bolt is connected to the brake shaft through a positioning mechanism. However, the positioning mechanism needs to be operated when installing or removing the locking rod head. In the high-altitude working environment of tower construction, this operation process makes it inconvenient to replace the locking rod head. In addition, the positioning mechanism also needs to bear torque when in use, which makes it very easy to be damaged. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a power tower construction and installation device to solve the problem of inconvenient replacement of locking pole heads in the above-mentioned background art.
[0005] This utility model provides the following technical solution: a power transmission tower construction and installation device, including a locking rod head, including a jacking handle assembly, a rotary drive assembly fixedly connected to the top of the jacking handle assembly, a brake shaft fixedly connected to the output end of the rotary drive assembly, a pin groove opened at the bottom of the locking rod head, and the shape and size of the pin groove being adapted to the brake shaft, a sliding groove provided on both sides of the pin groove, and an elastic locking block assembly provided in each of the sliding grooves, the outer sides of the two elastic locking block assemblies being set as slope surface a, and a locking groove provided on both sides of the pin groove, the output end of the jacking handle assembly passing through the rotary drive assembly to the inside of the brake shaft and connecting with the two elastic locking block assemblies, the output of the jacking handle assembly being used to control the two elastic locking block assemblies to retract into the sliding groove of the brake shaft.
[0006] Furthermore, the brake shaft is configured as a polygon.
[0007] Furthermore, the elastic locking block assembly includes a locking block body, with rail grooves at the top and bottom of the locking block body. A fixing block is slidably sleeved in the rail groove, and the fixing block is fixedly connected to the inner wall of the brake shaft groove. One side of the fixing block is connected to one end of the rail groove via a spring.
[0008] Furthermore, both of the elastic block assemblies have grooves on their front and back sides, with one side of the groove being a slope b; the bottom of the brake shaft has an accessory groove; the push handle assembly includes a main handle, the top of the main handle has a column groove, a push rod is slidably sleeved in the column groove, the push rod extends through to the top of the rotary drive assembly and is connected to a push contact; the side wall of the push handle assembly has a wall groove communicating with the column groove, a paddle is slidably sleeved in the wall groove, and the paddle is fixedly connected to the side wall of the push rod; the push contact is located inside the accessory groove, its top end extends through the brake shaft groove and is embedded in the groove abutting against the slope b.
[0009] Furthermore, the push contact includes a base plate and four columns, which are fixedly connected to the top of the base plate. The four columns are arranged in two groups, with two columns in each group. The two groups of columns are respectively connected to two elastic block assemblies. The two columns in one group are distributed and embedded in the grooves on the front and back of the elastic block assembly.
[0010] Furthermore, a wheel groove is formed at the top of the column, and a roller is rotatably fitted inside the wheel groove.
[0011] Furthermore, the rotary drive assembly includes a cylindrical shell with a through-hole at the top, into which a knob is rotatably fitted.

The knob has a shaft hole at the top that extends to the bottom, through which the output end of the push handle assembly passes.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This invention completes the installation of the locking rod head by inserting a brake shaft into the bottom groove of the locking rod head. During this process, the elastic locking block assembly automatically embeds itself into the groove to form an automatic locking effect. Compared with the existing locking rod head replacement process, this saves operation steps, making the replacement of the locking rod head more convenient and faster, and more suitable for high-altitude working environments in power tower construction. By setting a push handle assembly to connect with the elastic locking block assembly, the elastic locking block assembly can be controlled to achieve a retraction and unlocking effect. The structure of the push handle assembly and its cooperation with the elastic locking block assembly make the unlocking process simple and quick, further improving the convenience of the locking rod head. Furthermore, the shape of the brake shaft prevents torque from being transmitted to the elastic locking block assembly, preventing damage to the elastic locking block assembly due to pressure.

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] Reference Figure 1 and Figure 2This utility model provides a power transmission tower construction and installation device, including a locking rod head 4, a jacking handle assembly 1, a rotary drive assembly 2 fixedly connected to the top of the jacking handle assembly 1, a brake shaft 3 fixedly connected to the output end of the rotary drive assembly 2, a pin groove 5 at the bottom of the locking rod head 4, the shape and size of the pin groove 5 being adapted to the brake shaft 3, sliding grooves on both sides of the pin groove 5, and elastic locking block assemblies 7 being provided in each sliding groove, the outer surfaces of the two elastic locking block assemblies 7 being sloped a, and locking grooves 6 on both sides of the pin groove 5, the output end of the jacking handle assembly 1 penetrating through the rotary drive assembly 2 to the inside of the brake shaft 3 and connecting with the two elastic locking block assemblies 7, the jacking handle assembly... 1. The output controls the retraction of two elastic locking block assemblies 7 into the slide groove of the brake shaft 3. When installing the locking rod head 4, the pin groove 5 at its bottom end is inserted into the side wall of the brake shaft 3. During this process, the bottom edge of the pin groove 5 contacts the slope a of the elastic locking block assembly 7. By applying pressure to the locking rod head 4, the two elastic locking block assemblies 7 retract under the pressure. At this time, the brake shaft 3 can be fully inserted into the inner wall of the pin groove 5. When the two elastic locking block assemblies 7 are aligned with the two slots 6 on the inner wall of the pin groove 5, the elastic locking block assemblies 7 reset and embed into the slots 6 under the elastic action. This allows the locking rod head 4 to achieve both unlocking and locking, making the replacement process of the locking rod head 4 more convenient.
[0022] Reference Figure 2 The brake shaft 3 is set as a polygon. This setting prevents the brake shaft 3 from rotating inside the pin groove 5, thereby achieving a rotational positioning effect and preventing the elastic locking block assembly 7 from being damaged due to excessive force.
[0023] Reference Figure 3 The elastic locking block assembly 7 includes a locking block body 71. The top and bottom of the locking block body 71 are provided with rail grooves. A fixing block 72 is slidably sleeved in the rail groove. The fixing block 72 is fixedly connected to the inner wall of the slide groove of the brake shaft 3. One side of the fixing block 72 is connected to one end of the rail groove through a spring 73. When the elastic locking block assembly 7 retracts, the locking block body 71 moves into the slide groove of the brake shaft 3. Due to the inconvenient position of the fixing block 72, the spring 73 is compressed. When the elastic locking block assembly 7 is not under force, the elastic action of the spring 73 can cause the elastic locking block assembly 7 to spring back to its original position.
[0024] Reference Figure 2 , 4Both elastic locking block assemblies 7 have grooves 74 on their front and back sides, with one side of the grooves 74 being a slope b; the brake shaft 3 has a fitting groove 31 at its bottom; the push handle assembly 1 includes a main handle 11, with a column groove at the top of the main handle 11, in which a push rod 12 is slidably fitted; the push rod 12 extends through to the top of the rotary drive assembly 2 and is connected to a push contact 13; the side wall of the push handle assembly 1 has a wall groove communicating with the column groove, in which a paddle 121 is slidably fitted; the paddle 121 is fixedly connected to the side wall of the push rod 12; the push contact 13 is located inside the fitting groove 31, with its top end extending through... The locking rod head 4 is inserted into the groove of the brake shaft 3 and abuts against the slope b in the groove 74. When it is necessary to disassemble the locking rod head 4, only the paddle 121 needs to be pushed to complete the disassembly process of the locking rod head 4, which further improves the convenience of replacing the locking rod head 4. The principle is that the paddle 121 moves upward to drive the push rod 12 to move upward, and the push rod 12 pushes the push contact 13 to move upward. Thus, the push contact 13 applies an upward squeezing force to the slope b of the groove 74. Under the action of the slope b, the elastic block assembly 7 can have a lateral force to retract into the groove of the brake shaft 3, thereby allowing the elastic block assembly 7 to disengage in the slot 6.
[0025] Reference Figure 4 The push contact 13 includes a base plate 131 and four columns 132, which are fixedly connected to the top of the base plate 131. The four columns 132 are arranged in two groups, with two columns in each group. The two groups of columns 132 are respectively connected to two elastic locking block assemblies 7. The two columns 132 in one group are embedded in the grooves 74 on the front and back of the elastic locking block assembly 7. The push contact 13 contacts the slope b of the groove 74 with the top of the column 132. This arrangement ensures that the two elastic locking block assemblies 7 retract synchronously.
[0026] Reference Figure 4 The top of the column 132 has a wheel groove, and a roller 133 is rotatably fitted in the wheel groove. Since the column 132 contacts the slope wall b of the groove 74 and slides along the slope b, the frictional resistance can be reduced by setting the roller 133.
[0027] Reference Figure 2 The rotary drive assembly 2 includes a cylindrical shell 21. The top of the cylindrical shell 21 has a through-hole that extends into the interior. A knob 22 is rotatably fitted inside the through-hole. A drive motor 23 is installed on the side wall of the cylindrical shell 21. The output end of the drive motor 23 extends into the interior of the cylindrical shell 21 and is connected to the side wall of the knob 22 via a bevel gear meshing group 24. The top of the knob 22 has a through-hole that extends into the bottom. The shaft hole is used to push the output end of the handle assembly 1 through. In use, the drive motor 23 outputs rotational power, which causes the knob 22 to rotate under the transmission effect of the bevel gear meshing group 24, thereby controlling the rotation of the brake shaft 3.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
