[0002] In modern industrial production, the traction trolley is widely used in various material transportation scenes, and its operation relies on the traction of the steel wire rope. Because the traction trolley operating condition is complex, the tension of the steel wire rope is difficult to maintain stable and consistent when it moves back and forth. When the tension of the steel wire rope is too high, the contact part with the rack bears excessive pressure, which aggravates the friction between the two. When the tension is too low, the steel wire rope is prone to slack and swing, which will also cause abnormal friction with the rack. The unnecessary friction caused by inconsistent tension not only greatly shortens the service life of the steel wire rope of the traction trolley, but also increases the production cost and downtime maintenance time due to frequent replacement of the steel wire rope. At the same time, it also causes serious wear and tear to the rack, reduces the structural strength and stability of the rack, and affects the reliability and safety of the entire production system. The existing steel wire rope and rack are usually in direct contact without a wear -resisting structure, or only the friction under the conventional operating state is considered, and the effective improvement is not fully made for the universal problem of unstable tension, resulting in serious equipment wear and tear, and great influence on production efficiency and economic benefits.

[0023] In order to make the purpose, technical scheme and advantages of the present application clearer, the following will be further described in detail with specific examples and in reference to the drawings.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the specification herein is for describing specific embodiments only and is not intended to be limiting of the present application, for example, the terms "length", "width", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like specify relative positions according to the orientations shown in the drawings and are used for convenience and are not necessarily limiting.

[0026] In the specification and claims of the present application and the above description of the drawings, when an element is referred to as being "fixed to" or "mounted to" or "connected to" or "coupled to" another element, it can be directly or indirectly connected to the other element. For example, when an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

[0027] In addition, the reference herein to "embodiments" means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] As Figure 1The steel wire rope wear-resistant structure provided by the utility model is shown, and comprises: a frame 1, a plurality of wear-resistant structures 2 and a support 4, the bottom of the support 4 is vertically fixed to the bearing surface of a rack 5, the top of the support 4 is rigidly connected with the frame 1, the frame 1 is a closed guide channel, a plurality of rotatable wear-resistant structures 2 are symmetrically arranged on the inner periphery of the frame 1, and the steel wire rope 3 penetrates the inside of the frame 1 and is in rolling contact with the wear-resistant structures 2.

[0029] Further, the wear-resistant structure 2 comprises a rotating shaft 2.2 and a roller 2.1, the roller 2.1 is installed on the rotating shaft 2.2 through double-row angular contact bearings, the roller 2.1 can freely roll on the rotating shaft 2.2, and the roller is installed on the rotating shaft through the double-row angular contact bearings, so that axial and radial loads from different directions can be effectively borne. This enables the roller to still operate stably when rotating at a high speed and the steel wire rope exerts complex force, and greatly improves the stability and reliability of the wear-resistant structure.

[0030] Further, adjustable lock nuts are arranged at the two ends of the rotating shaft 2.2, the spacing between the adjustable lock nuts is adjusted to realize axial gap control, and the rotatable region can be adjusted based on the diameter of the steel wire rope. For example, when the tension of the steel wire rope changes, the gap can be adjusted to avoid axial movement of the roller and maintain stable rolling contact. On the other hand, when the bearing is worn to a certain extent, the gap can be compensated by adjusting the lock nuts, so that the bearing does not need to be replaced immediately, the maintenance cost is reduced, and the overall service life of the wear-resistant structure is prolonged.

[0031] Further, the rotating shaft 2.2 is detachably connected with the inner wall of the frame 1 through bolts, and the maintenance convenience is greatly improved. When the roller or the bearing in the wear-resistant structure needs to be replaced due to failure, the staff can quickly detach the bolts by using simple tools, take down the rotating shaft together with the components thereon from the frame, and then maintain or replace the rotating shaft.

[0032] Further, the support 4 is a telescopic structure, and the adaptability of the device is increased. In different production scenes, the height of the rack may be different, or the height of the steel wire rope needs to be adjusted according to actual process requirements. In some embodiments, the telescopic structure comprises two tubular components nested with each other, a plurality of positioning holes are arranged on the tubular components, a positioning pin matched with the positioning holes is inserted into different positioning holes to realize the telescopic height of the support. The telescopic structure is composed of two tubular components nested with each other, and the height is adjusted through the positioning holes and the positioning pin, which has the advantages of simple operation and accurate positioning. The staff only needs to insert the positioning pin into different positioning holes to quickly and accurately adjust the height of the support to the required position, and the cooperation of the positioning pin and the positioning hole can provide stable support to ensure that the height of the support does not change due to external force during use. Compared with some complex height adjustment mechanisms, this structure design has lower cost, higher reliability, and is also convenient for later maintenance and maintenance.

[0033] Further, the frame 1 adopts a segmented quick-release structure, and each segment is detachably connected through a conical positioning pin and a hydraulic locking joint. When the equipment is maintained, each segment of the frame can be quickly disassembled, so that the internal wear-resistant structure, steel wire rope and other components can be conveniently and comprehensively inspected and repaired.

[0034] Further, as shown in Figure 1 the frame 1 is in the shape of an inverted trapezoid, the wear-resistant structure arranged at the lower part of the inverted trapezoidal frame has a length shorter than that arranged at the upper part of the inverted trapezoidal frame, and the lengths of the wear-resistant structures arranged at the left and right sides of the inverted trapezoidal frame are equal. The space at the upper part of the inverted trapezoidal frame is relatively large, which can adapt to the swing of the steel wire rope during operation and reduce the wear caused by collision. The space at the lower part is relatively small, which can better constrain the steel wire rope and prevent it from excessive swinging. The wear-resistant structure arranged at the lower part of the inverted trapezoidal frame has a relatively short length, which can avoid interference with the components such as the rack below. The equal lengths of the wear-resistant structures arranged at the left and right sides of the inverted trapezoidal frame ensure uniform support and wear protection for the steel wire rope on the left and right sides, thereby improving the stability and wear resistance of the steel wire rope during operation.

[0035] Further, a transparent observation window is arranged on the frame 1, and the observation window is made of high-strength organic glass.

[0036] Further, a shock-absorbing rubber pad is arranged at the rigid connection part of the frame 1 and the support 4, and the thickness of the rubber pad is 5-8 mm. The rubber pad can effectively buffer the vibration caused by the movement of the steel wire rope, avoid damage to the support and the rack bearing surface, and prolong the service life of the entire structure.

[0037] The device can achieve the following technical improvements:

[0038] (1) Reduce friction loss: The wear-resistant structure composed of rollers is arranged around the frame, which successfully converts the sliding friction between the steel wire rope and the rack into rolling friction, greatly reducing the friction coefficient. This conversion effectively reduces the additional friction loss caused by the inconsistent tension of the steel wire rope, thereby improving the operation efficiency.

[0039] (2) Enhance the stability and safety of the rack: The wear degree of the rack caused by the friction of the steel wire rope is reduced, and the structural strength can be maintained stable for a long time, which enhances the reliability and safety of the entire production system and reduces the risk of safety accidents caused by rack damage.
