Description

Technical Field

[0001] This utility model relates to the field of power foundation construction technology, specifically a modular construction device for power transmission lines. Background Technology

[0002] The construction of power transmission lines traverses areas with complex terrain, mostly mountainous forests, hills, swamps, and farmland. The construction period is tight and the effective construction period is short. The foundation construction of power transmission lines is a very important link in the three stages of line construction: foundation construction, tower erection, and conductor and ground wire stringing. The construction and maintenance cycle of line foundations is long, requiring 28 days for concrete pouring and curing. The characteristics of foundation construction are that there are many line foundations, which are distributed linearly and spread across a wide area.

[0003] However, most of the current line foundation construction is done manually, with a lack of specification limits, and the splicing of the formwork used for pouring is unstable, which makes the formwork easy to tilt and pouring failure. Therefore, this utility model provides a modular construction device for power transmission lines to meet people's needs. Utility Model Content

[0004] This utility model provides a modular construction device for power transmission lines, which can effectively solve the problems mentioned in the background art, where the construction of line foundations is mostly carried out manually, lacks specification limitations, and the interlocking of the formwork used for pouring is unstable, leading to the formwork being prone to tilting and pouring failure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular construction device for transmission lines, comprising a cast-in-place foundation pile, wherein a modular splicing mechanism is provided on the outer side of the cast-in-place foundation pile;

[0006] The modular splicing mechanism includes a splicing template, a positioning rod, a positioning groove, an outer splicing strip, an inner splicing strip, and auxiliary protrusions;

[0007] The outer perimeter of the foundation pile is fitted with a splicing template. The bottom of each splicing template is symmetrically connected with a positioning rod, and the top of each splicing template is symmetrically provided with a positioning groove. One end of each splicing template is connected with an outer splicing strip, and the other end of each splicing template is connected with an inner splicing strip. Auxiliary protrusions are symmetrically installed on the surface of the splicing template.

[0008] Preferably, the positions of the positioning rod and the positioning groove correspond to each other, and the length and width of the positioning rod are the same as the length and width of the positioning groove.

[0009] Preferably, one end of the outer splicing strip and one end of the inner splicing strip are located on the same vertical plane, and the outer splicing strips and inner splicing strips of two adjacent splicing template ends are in contact with each other.

[0010] Preferably, a positioning support mechanism is provided on one side of the bottom of the splicing template;

[0011] The positioning support mechanism includes a support block, a mounting pin, a limiting notch, a connecting block, a mounting sleeve, an adjusting screw, a pressing block, a rotating operating block, and a through hole;

[0012] A support block is installed on one side of the bottom of the splicing template. The bottom end of the support block is symmetrically connected with mounting pins. A limit notch is opened at one end of the support block. A connecting block is connected to the top end of the support block. An mounting sleeve is installed in the middle of the connecting block. An adjusting screw is installed through the middle of the mounting sleeve. A pressing block is connected to the bottom end of the adjusting screw. A rotating operating block is connected to the top end of the adjusting screw. A through hole is opened in the middle of the rotating operating block.

[0013] Preferably, the support block is located on the surface of the connection position of two adjacent splicing templates, and the outer splicing strip and the inner splicing strip are fitted together and embedded inside the limiting notch.

[0014] Preferably, the adjusting screw and the mounting sleeve are connected by a thread, the adjusting screw moves through the connecting block, and the pressing block is located below the connecting block.

[0015] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0016] 1. Equipped with a modular splicing mechanism, the splicing templates are interlocked to create a certain pouring space, making pouring more convenient and faster. The positioning rods and positioning grooves work together to strengthen the connection between adjacent splicing templates, accommodating pouring at different heights. The splicing and installation method is simple. At the same time, the outer and inner splicing strips are interlocked to ensure that the edges of adjacent splicing templates are pressed together. After the splicing templates are spliced ​​around each other, they limit and support each other, making the splicing templates more stable and preventing the splicing templates from tilting inward, which could lead to pouring failure.

[0017] 2. A positioning support mechanism is provided, which uses installation pins to position and install the support block, ensuring that the support block is tightly attached to the surfaces of the outer and inner splicing strips. This provides limiting support for adjacent splicing templates, preventing them from tilting or shifting outwards. Simultaneously, the cooperation between the adjusting screw and the pressing block greatly facilitates the subsequent lifting and removal of the support block from the ground. Furthermore, the rotating operating block and the through hole provide two rotation operation methods: the adjusting screw can be rotated directly using the rotating operating block, or a cylindrical object can be inserted into the through hole for rotation, making it more convenient to use.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-4 As shown, this utility model provides a technical solution, a modular construction device for power transmission lines, including a cast-in-place foundation pile 1, and a modular splicing mechanism 2 is provided on the outside of the cast-in-place foundation pile 1.

[0029] The modular splicing mechanism 2 includes a splicing template 201, a positioning rod 202, a positioning groove 203, an outer splicing strip 204, an inner splicing strip 205, and an auxiliary protrusion 206;

[0030] A splicing template 201 is fitted around the outer perimeter of the foundation pile 1. Positioning rods 202 are symmetrically connected to the bottom of each splicing template 201, and positioning grooves 203 are symmetrically formed at the top of each template. The positions of the positioning rods 202 and the positioning grooves 203 correspond to each other. The length and width of the positioning rods 202 are the same as the length and width of the positioning grooves 203. One end of the splicing template 201 is connected to an outer splicing strip 204, and the other end is connected to an inner splicing strip 205. One end of the outer splicing strip 204 and one end of the inner splicing strip 205 are located on the same vertical plane. The outer splicing strips 204 and inner splicing strips 205 at the ends of two adjacent splicing templates 201 are fitted together. The surface of the splicing template 201 is symmetrically equipped with auxiliary protrusions 206. The splicing templates 201 are spliced ​​together to create a certain pouring space for construction, making the pouring more convenient and faster. The positioning rods 202 and positioning grooves 203 work together to strengthen the connection between adjacent splicing templates 201, so as to meet the pouring construction at different heights. The splicing installation method is simple. At the same time, the outer splicing strips 204 and the inner splicing strips 205 are spliced ​​together to make the edges of adjacent splicing templates 201 squeeze and fit together. After the splicing templates 201 are spliced ​​around each other, they limit and support each other, making the splicing templates 201 more stable after splicing and preventing the splicing templates 201 from tilting inward and causing the pouring construction to fail.

[0031] A positioning support mechanism 3 is provided on one side of the bottom of the splicing template 201;

[0032] The positioning support mechanism 3 includes a support block 301, a mounting pin 302, a limiting notch 303, a connecting block 304, a mounting sleeve 305, an adjusting screw 306, a pressing block 307, a rotating operating block 308, and a through hole 309.

[0033] A support block 301 is installed on one side of the bottom of the splicing template 201. A mounting pin 302 is symmetrically connected to the bottom end of the support block 301. A limiting notch 303 is formed at one end of the support block 301. The support block 301 is located on the surface of the connection position between two adjacent splicing templates 201. The outer splicing strip 204 and the inner splicing strip 205 are fitted together and embedded inside the limiting notch 303. A connecting block 304 is connected to the top end of the support block 301. An installation sleeve 305 is installed in the middle of the connecting block 304. An adjusting screw 306 is installed through the middle of the installation sleeve 305. A pressing block 307 is connected to the bottom end of the adjusting screw 306. The adjusting screw 306 and the installation sleeve 305 are connected by threads. The adjusting screw 306 moves through the connecting block 304. The pressing block 307 is located below the connecting block 304. The top of the adjusting screw 306 is connected to a rotating operating block 308. The rotating operating block 308 has a through hole 309 in the middle. The support block 301 is positioned and installed using the mounting pin 302, so that the support block 301 is in close contact with the surface of the outer splicing strip 204 and the inner splicing strip 205. This provides a limiting support for the adjacent splicing template 201 and prevents the splicing template 201 from tilting or shifting outward. At the same time, the cooperation between the adjusting screw 306 and the pressing block 307 greatly facilitates the subsequent lifting and pulling of the support block 301 from the ground. The rotating operating block 308 and the through hole 309 provide two rotation operation methods. The adjusting screw 306 can be rotated directly using the rotating operating block 308, or a cylindrical object can be inserted into the through hole 309 for rotation operation, making it more convenient to use.

[0034] The working principle and usage process of this utility model are as follows: First, the staff determines the location where modular pouring construction is required according to the construction plan, takes the splicing template 201, inserts the positioning rod 202 at its bottom end into the soil, and the four splicing templates 201 are arranged in a square with their edges in contact with each other. The outer splicing strip 204 of the edge of the splicing template 201 and the inner splicing strip 205 of the adjacent splicing template 201 are tightly fitted together. The outer splicing strip 204 and the inner splicing strip 205 limit each other so that the splicing template 201 will not tilt outward. At the same time, according to the height requirements of the pouring construction, the splicing templates 201 can be taken and stacked upward. The positioning rod 202 and the positioning groove 203 correspond to each other so that the upper and lower adjacent splicing templates 201 are connected to each other.

[0035] Then, the staff took the support block 301 and placed it on the outside of the contact position of the adjacent splicing template 201. Using the installation pin 302 inserted into the soil, the support block 301 was positioned and installed so that the outer splicing strip 204 and the inner splicing strip 205 were fitted together and embedded in the limiting notch 303. The support block 301 was fitted on the outside and played a supporting and limiting role for the splicing template 201, which improved the installation stability of the splicing template 201 and prevented the splicing template 201 from tilting or shifting outward.

[0036] Subsequently, concrete is poured into the space surrounding the splicing template 201. The concrete will gradually solidify in the space formed after the splicing template 201 is assembled, forming the foundation pile 1 required for the line construction. After solidification, the worker holds the rotating operating block 308 to rotate the adjusting screw 306, or the worker takes a cylindrical rod and inserts it into the through hole 309 to extend the rotating force rod, which acts as a lever to rotate the adjusting screw 306. This causes the extrusion block 307 to gradually descend and press against the ground. After the adjusting screw 306 is continuously rotated, the extrusion block 307 is blocked by the ground, which causes the installation sleeve 305 to move upward, eventually lifting the support block 301. The installation pin 302 is pulled out of the soil, the support block 301 is removed, and the splicing template 201 is separated from the solidified foundation pile 1 using the auxiliary protrusion 206 for subsequent reuse.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
