Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway track embedded parts production, specifically an adjustable fixing device for railway track embedded parts. Background Technology
[0002] In railway track construction, the precise installation of embedded parts (such as sleeper bolts and fastener bases) is crucial to the stability, smoothness, and train operation safety of the track structure. Traditional methods for fixing embedded parts typically involve directly pouring concrete or post-installing anchors.
[0003] Existing railway track embedded parts are usually composed of a base plate and multiple steel bars. During the fixing process, it is necessary to manually hold the steel bars and fix the connection between the steel bars and the base plate. In actual operation, the steel bars are prone to deviate at a large angle, which can easily cause large errors in the embedded parts.
[0004] Therefore, it is necessary to design a new type of adjustable fixing device for railway track pre-embedded parts to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide an adjustable fixing device for railway track embedded parts to solve the problems mentioned in the background art.

A clamping plate is provided at one end of the second support plate.
[0010] Preferably, a plurality of pin holes are provided on the shelf plate, and a pin rod matching the pin holes is provided on the adjusting block.
[0011] Preferably, a support frame is provided at the bottom of the fixed seat.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. In the present utility model, by setting the telescopic component, the screw rod and sleeve mechanism in the telescopic component realizes multi-directional synchronous adjustment under the linkage of the motor, the conical gear ring and the bevel gear. In addition, the chute on the shelf plate cooperates with the "C"-shaped adjusting block, and combined with the positioning of the pin hole-pin rod, the height of the fixture can be quickly adjusted to meet the vertical positioning requirements of different embedded parts, and it can reduce the steel bar offset or elevation error caused by traditional manual positioning.
[0014] 2. In the present utility model, by setting the fixture, the fixture adopts a rhombic link mechanism driven by an electric push rod (the first support plate and the second support plate are hinged). By stretching and contracting the electric push rod, the opening and closing of the clamping plate can be controlled, realizing the automatic clamping and releasing of the steel bar. The clamping force is stable and there is no damage. At the same time, the design of the support frame lifting the fixed seat is convenient for keeping the device horizontal during the concrete pouring stage and reducing vibration interference.
