Description

Technical Field

[0001] This utility model belongs to the technical field of railway construction auxiliary equipment, specifically relating to a positioning auxiliary device for pre-embedded parts of railway contact wire pole foundation. Background Technology

[0002] The overhead contact line pole is an important component of electrified railway transmission lines. It is erected above the electrified railway and its main purpose is to supply power to the electric locomotives through the contact wire on it to ensure the normal operation of the electric locomotives.

[0003] Railway catenary pole foundations are generally small and numerous, typically consisting of a concrete main body and embedded catenary pole foundation components positioned at the upper middle part of the concrete main body. The construction method involves erecting a catenary pole foundation formwork on the outside of the concrete main body, then placing and fixing the square embedded catenary pole foundation components inside the formwork. Concrete is then poured inside the formwork, and after it hardens, the concrete main body is formed. Finally, the formwork is removed. Because there is no dedicated positioning device for the embedded catenary pole foundation components, the installation process is cumbersome and prone to inaccurate positioning, making the overall construction time-consuming and labor-intensive.

[0014] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Taking a railway project as an example: The contact wire pole foundations for this project are constructed using cast-in-place concrete. There are a total of 80 contact wire pole foundations, and the construction section includes a curved section. Of these, 60 foundations are located on straight sections, and 20 are located on curved sections. To improve the installation efficiency of the embedded parts for the contact wire pole foundations, this project uses the railway contact wire pole foundation embedded part positioning auxiliary device provided by this utility model for the installation of the embedded parts. This device is simple to manufacture, easy to assemble and disassemble, and its installation method is simple and beneficial for on-site construction.

[0016] like Figures 1 to 3 As shown, the positioning auxiliary device for the railway contact wire pole foundation embedded part provided in this embodiment includes: a top support 1, a spiral rod 2, and a telescopic unit; the top support 1 is closely attached to the top edge and side of the contact wire pole foundation embedded part 7; the bottom support 3 abuts against the inner surface of one side of the contact wire pole foundation template 6; the telescopic unit is connected between the top support 1 and the spiral rod 2.

[0017] The top support 1 is an inverted L-shaped plate structure composed of a horizontal plate and a vertical plate, wherein the horizontal plate is hung on the top edge of one side of the embedded part 7 of the contact wire pole foundation, and the vertical plate is attached to the side of the embedded part 7 of the contact wire pole foundation.

[0018] The base 3 has a disc-shaped structure.

[0019] The telescopic unit includes a spiral rod 2, a spiral sleeve 4, and a knob 5; one end of the spiral rod 2 is fixed to the lower outer side of the vertical plate on the top support 1; one end of the spiral sleeve 4 is fixed to the bottom support 3, and the other end is sleeved on the other end of the spiral rod 2; the knob 5 is set on the spiral sleeve 4, and by rotating the spiral sleeve 4 through the knob 5, the spiral sleeve 4 can move freely on the spiral rod 2.

[0020] The railway contact wire pole foundation embedded part positioning auxiliary device also includes a rubber pad installed on the inner side of the top support 1 to increase the friction between the top support 1 and the contact wire pole foundation embedded part 7, and to protect the contact wire pole foundation embedded part 7.

[0021] The working principle of the railway catenary pole foundation embedded part positioning auxiliary device provided by this utility model is described below:

[0022] When constructing railway contact network pole foundations, firstly, a contact network pole foundation template 6 is erected on the outside of the concrete main body of the railway contact network pole. Then, construction workers rotate the knob 5 in the positioning auxiliary device for the embedded parts of the railway contact network pole foundation, which in turn rotates the spiral sleeve 4, thereby adjusting the telescopic unit to its minimum length. Then, the embedded part 7 of the railway contact network pole foundation is placed at the target position inside the contact network pole foundation template 6. The length of the telescopic unit is then appropriately extended by rotating the spiral sleeve 4 using the knob 5, until the horizontal plate on the top support 1 hangs on one side of the top edge of the embedded part 7, and the vertical plate is attached to the side of the embedded part 7. Simultaneously... The base support 3 is placed against the inner surface of one side of the contact wire pole foundation template 6 until the device is completely fixed between the railway contact wire pole foundation embedded part 7 and the railway contact wire pole foundation template 6. One of these devices is installed on each side of the railway contact wire pole foundation embedded part 7. Then, the position of the railway contact wire pole foundation embedded part 7 is checked. If the installation position is found to be inaccurate, the telescopic unit can be finely adjusted until the railway contact wire pole foundation embedded part 7 is accurately positioned. After that, concrete is poured into the contact wire pole foundation template 6. Before the concrete is smoothed, the railway contact wire pole foundation embedded part positioning device is removed, and then the next railway contact wire pole foundation construction is carried out. Finally, the above steps are repeated until all construction is completed. The removed railway contact wire pole foundation embedded part positioning device is cleaned and placed in a warehouse for storage and reuse.

[0023] The above are merely preferred embodiments of the present utility model and do not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
