Description

Technical Field

[0001] The present invention relates to the field of sound barrier installation, and specifically to a limit track for sound barrier connection. Background Art

[0002] Sound barriers are mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources. They are divided into reflective sound barriers for pure sound insulation and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method, referring to a wall-like structure set beside railways and highways to reduce the impact of traffic noise on nearby residents.

[0003] Currently, when temporarily building a sound barrier at a construction site, due to the limitations of the construction site, the ground is sometimes uneven, making it difficult to fix the installation base plate. At the same time, when using sound barriers of different sizes, the spacing of the bases is not convenient to adjust, reducing the versatility. Summary of the Invention

[0004] The purpose of the present invention is to provide a limit track for sound barrier connection to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A limit track for sound barrier connection includes a track plate. An installation frame is slidably installed in the track plate. A first installation groove is opened in the upper part of the installation frame. Threaded holes are provided on the side wall of the first installation groove, and fastening bolts are threadedly installed. Positioning grooves are symmetrically opened on the end face of the track plate. Transverse plates are symmetrically installed at the ends of the installation frame. N-shaped frames are symmetrically installed at the ends of the transverse plates through screws. A positioning rod is inserted and installed in the N-shaped frame. A first limit block is installed on the positioning rod. A top spring is provided on the upper surface of the first limit block, and the top spring is sleeved on the positioning rod.

[0008] Preferably, foot nails are provided at the bottom of the bottom plate. The foot nails are conical, with a large upper end and a small lower end. Multiple groups of foot nails are provided, arranged in a linear, evenly spaced and equidistant array.

[0009] Preferably, the lifting control structure includes a support cylinder, a threaded cylinder, and a threaded rod. The support cylinder is installed on the upper end surface of the extension frame. The threaded cylinder is rotatably installed at the upper end of the support cylinder. The threaded rod is installed in the threaded cylinder by internal threads. The upper end of the threaded rod is installed on the top wall of the support frame, and the lower part of the threaded rod is inserted into the support cylinder.

[0010] Preferably, a guide shaft is installed in the track plate. The guide shaft is a cylindrical rod structure, and the mounting frame is slidably installed on the guide shaft.

[0011] Preferably, a second installation groove is formed in the lower side wall of the mounting frame. The second installation groove is a "C"-shaped groove structure, and rollers are symmetrically and rotatably installed in the second installation groove.

[0012] Preferably, the rolling surface of the roller conforms to the inner wall structure of the roller groove. The roller grooves are symmetrically formed in the inner wall of the track plate, and the length of the roller groove is the same as that of the guide shaft.

[0013] Preferably, the positioning rod is a cylindrical rod structure, and a second limiting block is installed on the side wall of the positioning rod. The second limiting block is a rectangular block structure, and the limiting block is slidably installed in the strip-shaped groove. The strip-shaped groove is formed in the N-shaped frame, and a top groove is provided at the end of the strip-shaped groove. The top groove is formed on the upper surface of the N-shaped frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In the present invention, a track plate is provided, and a mounting frame is slidably arranged in the track plate. The mounting frame is fixed by a positioning rod. In this way, it is convenient to adjust the position of the mounting frame according to the actual length dimension of the sound barrier and fix it with the positioning rod. After the width between the mounting frames is appropriate, the sound barrier is installed. At the same time, a support frame and an extension frame are arranged under the track plate, so that in the actual operation process, by rotating the threaded cylinder, the support cylinder and the extension frame can be adjusted to change the total length of the support frame and the extension frame to meet different installation requirements and installation terrains.
