Description

Technical Field

[0001] This invention belongs to the field of rail transit auxiliary tools technology, specifically relating to a handrail raising device for various railway flatcars. Background Technology

[0002] In railway transportation operations, flatcars are commonly used transport equipment, and their handrails are crucial for ensuring the safety of workers getting on and off the car and during operations. However, existing flatcar handrails generally suffer from the problem of being too low. When workers stand on the train's footrests, the handrail height is not compatible with the comfortable grip height, requiring them to bend over and stoop to hold it. This not only results in an unnatural grip posture but also causes abnormal stress on the arms and waist, easily leading to fatigue over long periods. Furthermore, excessively low handrails fail to provide stable support, increasing the risk of imbalance and falls during boarding, disembarking, or operations, and failing to meet the safety and comfort requirements of actual operations. Therefore, there is an urgent need for a device that can adapt to existing flatcars and has adjustable handrail height to solve the problems of difficult gripping and poor safety caused by the current handrails being too low. Summary of the Invention

[0003] The present invention addresses the above-mentioned problems by providing a handrail raising device for various railway flatcars.

The hook is vertically inserted into the foot pedal of a railway flatcar from top to bottom for fixation. The foot pedal panel is for users to step on, and uprights are symmetrically arranged on the left and right sides of the upper surface of the foot pedal panel. A support assembly is mounted on a slide rail assembly and has two working states: supporting and retracting. The first support plate of the support assembly is rotatable so as to fit tightly against the vertical surface of the railway flatcar and realize the force support function. A slide rail assembly, which is fixedly installed on a column one; An upper ladder assembly is mounted on a slider in a slide rail assembly and can slide relative to a slide rail in the slide rail assembly; A locking assembly is slidably mounted on the upper ladder frame assembly along the height direction. After the locking assembly is opened, it is inserted into the handle of the railway flatcar and then locked to fix it, thereby realizing the fixed connection between the locking assembly and the handle of the railway flatcar. A telescopic grip assembly is slidably mounted on the upper part of the upper ladder assembly to allow for multiple adjustments to suit the needs of users of different heights.

[0005] Furthermore, the slide rail assembly includes a slide rail, with supporting square tubes symmetrically fixed on the left and right sides of the lower surface of the slide rail. The supporting square tubes are fixedly connected to corresponding columns. Several sliders are slidably mounted on the slide rail, and the sliders are fixedly connected to the upper ladder frame assembly. Dustproof side plates are provided on the front and rear sides of the slide rail, and the dustproof side plates are welded and fixed to the supporting square tubes. Multiple positioning holes are provided on the dustproof side plates, and positioning pins are inserted into the positioning holes to achieve positioning between the dustproof side plates and the upper ladder frame assembly. Two sets of connecting modules are symmetrically arranged below the slide rail, and the two sets of connecting modules are located between two supporting square tubes. Each connecting module includes a second support plate and a lower extension plate, which are welded and fixed to the dustproof side plates. The second support plate is connected to the support assembly via a hinge, and the lower extension plate is used to support the support assembly in the working state.

[0006] Furthermore, the support assembly includes a connecting plate, which is connected to the second support plate via a hinge. The connecting plate is L-shaped. When the support assembly is in operation, the connecting plate is in contact with the lower extension plate, and the lower extension plate provides support for the connecting plate.

The other end of the second telescopic tube is fixedly connected to one end of a movable hinge, and the other end of the movable hinge is fixedly connected to the first support plate.

[0007] Furthermore, the upper ladder assembly includes a ladder square tube, which is fixedly connected to the slider. Columns two are fixedly installed on both the left and right sides of the upper surface of the ladder square tube, and spring clips are installed on the upper part of the columns two.

[0008] Furthermore, the locking assembly includes two sliding sleeves II, which are slidably mounted on the column II. A Torx screw is threaded onto each sliding sleeve II to facilitate relative fixation between the sliding sleeve II and the column II. A limiting crossbar is welded between the two sliding sleeves II. Two sliding sleeves I are slidably mounted on the limiting crossbar. A fixed sleeve is fixedly welded onto each sliding sleeve I. The fixed sleeve is slidably connected to the telescopic sleeve and is relatively fixed via a pin. A locking buckle is fixedly connected to the other end of the telescopic sleeve.

When facing different models of flatcars, the positioning hole of the slide rail component can be used to flexibly adjust the handrail support position, ensuring the stability and adaptability of the operator's standing operation. For operators of different heights, the telescopic handle component can slide along the column and be locked by spring buckle to form a handrail support height that meets different heights. In addition to the core function of increasing the height of the handrail, the device adds a safety belt hanging ring structure to fix the operator's safety belt, effectively reducing the grip load. It has multiple technical advantages such as multi-model adaptability, multi-height adaptability, and safety protection. Attached Figure Description
