[0001] The invention belongs to the technical field of railway derailment rescue slings, in particular to a carbon fiber multifunctional sling with adjustable lower rope length. Background Art

[0002] my country's railway development tends to be high-speed and heavy-loaded. Once a railway accident occurs, the relevant railway departments usually adopt the hoisting method to carry out rescue operations. The existing lifting beam equipment used in the hoisting rescue needs to be equipped with corresponding ropes for different types of vehicles, resulting in too many types and specifications of rescue ropes, and they are often placed in a chaotic and stacked manner.

[0003] In addition, the currently commonly used single-supported lifting beam needs to be equipped with additional "whole lifting accessories" when performing whole lifting operations to separate the ropes, causing excessive local stress and affecting operational safety. Summary of the invention

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0020] like Figure 1As shown, the carbon fiber multifunctional sling with adjustable lower rope length of the present invention includes a suspension beam, and six mounting through holes are arranged on the side of the suspension beam, the six mounting through holes include three first mounting through holes arranged on the left side of the center of the suspension beam and three second mounting through holes arranged on the right side of the center of the suspension beam, the three first mounting through holes and the corresponding three second mounting through holes are symmetrically arranged about the center of the suspension beam, and the three mounting through holes located on the same side of the center of the suspension beam are evenly arranged along the length direction of the suspension beam, a hollow pin shaft 1 is penetrated through the mounting through hole, and a circular baffle 2 is arranged at the front and rear ends of the hollow pin shaft 1, the circular baffle 2 arranged on the front side of the suspension beam and the circular baffle 2 arranged on the rear side of the suspension beam are symmetrical about the center of the suspension beam, a gap is arranged between the circular baffle 2 and the side of the suspension beam for setting a suspension rope 4, and when in use, a suspension rope 4 is arranged on part or all of the hollow pin shaft 1, and the suspension rope 4 is symmetrically arranged along the center of the suspension beam, such as Figure 3 shown.

[0021] The left and right bottoms of the hanging beam are welded with bases 3, such as Figure 2 As shown, the base 3 includes a box structure with an opening 32 facing downward and four supporting legs 31 arranged below the box structure. The two supporting legs 31 located on the same side of the hanging beam are used to limit the left and right directions of the hanging rope 4. The box structure is provided with an opening 32 for the hanging rope 4 to pass through. The height of the opening 32 is 100 mm, which is convenient for the hanging beam to extract the hanging rope 4 when it is in the ground state. The box structure includes a bottom plate, a left side plate 34, a right side plate 35, a front side plate and a rear side plate 36. A 1 / 4 arc structure 33 with a radius of 100 mm is provided between the bottom plate of the box and its front side plate and rear side plate 36, which provides a circular transition for the contact of the hanging rope 4 and improves the stress condition. During the whole lifting operation, the hanging rope 4 exerts a large lateral pulling force on the hollow pin shaft 1 located on the far left or far right, which can distribute the stress on the beam body with higher strength. At the same time, the base 3 is supported by the left side plate 34 and the right side plate 35, which can effectively alleviate the situation where the lateral pulling force causes excessive local stress on the hanging beam.

[0022] The surface of the suspension beam steel plate is provided with a carbon fiber coating. The carbon fiber coated suspension beam steel plate is formed into a composite plate process as a whole, which increases the overall tensile and bending resistance and improves the tensile strength. At the same time, the carbon fiber composite process also protects the suspension beam, avoids rust problems caused by factors such as use and storage environment, and increases the overall aesthetics.

[0023] A real-time online tension detection device is provided on the hanging beam. The online tension detection device includes a strain gauge, a data acquisition and wireless transmission device and a mobile phone terminal. The strain gauge is provided on the left and right sides of the hanging beam. The strain gauge is connected to the data acquisition and wireless transmission device through a wire. The data acquisition and wireless transmission device is electrically connected to the mobile phone terminal. The mobile phone terminal is a mobile phone terminal with a display screen. The wire is inside the carbon fiber coating. The wiring is completed before the carbon fiber coating and the hanging beam steel plate are composited. By providing a real-time online tension detection device, an online monitoring function can be realized, specifically: (1) real-time display of the tension value of the sling during the rescue operation; (2) reading the stress response of the corresponding measuring point on the beam; (3) providing a danger alarm function. By setting a threshold value, an alarm can be issued when the tension of the sling 4 is too large due to overloading or jamming, thereby ensuring the safety of the operation; (4) the mobile phone terminal is provided with an animation demonstration function to help on-site users quickly understand the rope winding methods of different vehicle models, which is convenient for on-site operation; and improves the modernization and intelligence level of rescue equipment.

[0024] The sling of the present invention solves the problem of pairing ropes with vehicle types during on-site use, and realizes the function of one rope for multiple uses. At the same time, the design of the base 3 replaces the original whole lifting accessories, improves the overall strength, ensures operation safety, has good economic and social benefits, and does not require additional accessories. It is universally applicable to both whole lifting and single-end lifting operations.

[0025] It should be noted that the mobile phone terminal of the present application can also be replaced by other mobile terminals.

[0026] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. It cannot be determined that the specific embodiments of the present invention are limited to this. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the present invention, which should be regarded as belonging to the present invention and the scope of patent protection determined by the submitted claims.
