Description

Technical Field

[0001] This utility model relates to the technical field of copper alloy plate and strip production equipment, specifically to a wire rope tension adjustment device for a threading trolley. Background Technology

[0002] In the production of precision copper strip, the strip needs to pass through various production fixtures on the equipment. There are different methods for threading the strip. Traditionally, a stitching machine and a shearing machine work together to connect the strip ends and pull the strip to achieve continuous production. However, due to the long travel time of the production line fixtures, the threading process generates excess waste. Therefore, using a threading trolley can save more production time and avoid waste generation.

[0003] The threading trolley is pulled by four steel wire ropes. Due to the extensibility of the steel wire ropes and the need to replace them, the traction steel wire ropes will have different deformations and tensions. Adjusting the tension of the steel wire ropes on the drum is ineffective and time-consuming. Because the steel wire ropes are not evenly stressed, the threading trolley may derail or the steel wire ropes may break. This situation threatens personal safety and equipment safety and affects the production line's production progress. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a wire rope tension adjustment device for threading trolleys, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model discloses a wire rope tension adjustment device for a trolley, the technical solution of which includes a support base, a guide wheel and a tension wheel, the guide wheel being rotatably connected to the support base, and two sets of guide wheels being provided;

[0006] The tension wheel is connected to the support base via an adjustment component. The tension wheel is located between two sets of guide wheels. Under the action of the adjustment component, the tension wheel is moved closer to or further away from the guide wheels to adjust the tension of the wire rope. The overall structure is based on the support base. The adjustment component and the guide wheels are rigidly connected, which can withstand large tension loads and is suitable for high-intensity working conditions during the traction process of the wire rope threading trolley.

[0007] The guide wheel is also equipped with an anti-derailment component to prevent the wire rope from detaching from the wheel. The improved tension uniformity avoids risks such as derailment of the threading trolley and wire rope breakage, ensuring personal and equipment safety.

[0008] In a preferred embodiment of this utility model, the adjusting assembly includes an adjusting screw and a hinge seat. The adjusting screw is slidably connected to the support base via a support block. The adjusting screw is locked and limited between itself and the support block by a locking nut. The adjusting screw is rotatably connected to the tension wheel via the hinge seat.

[0009] As a preferred technical solution of this utility model, the adjusting screw is engaged with the locking nut. There are two sets of locking nuts, which are symmetrically arranged on both sides of the support block. By adopting the manual adjustment method of adjusting screw and locking nut, no additional power source is required. The tension can be adjusted by simply rotating the adjusting screw. The operation is simple and can quickly respond to the on-site adjustment needs, solving the problem of time-consuming and laborious adjustment of traditional drum.

[0010] As a preferred technical solution of this utility model, the anti-detachment component is a U-shaped shell, and a protrusion and a limiting screw are provided on the side of the anti-detachment component facing the guide wheel. An annular groove corresponding to the position of the protrusion and the limiting screw is opened on the guide wheel.

[0011] As a preferred technical solution of this utility model, the protrusion is hemispherical, and the opposite ends of the limiting screw and the guide wheel are provided with rounded corners. The anti-detachment component on the guide wheel forms a double anti-detachment mechanism through the cooperation of the protrusion, the limiting screw and the annular groove, which can effectively prevent the wire rope from detaching from the wheel.

[0012] As a preferred technical solution of this utility model, a connecting block is provided on the other side of the anti-detachment component. The connecting block is connected to the support base by a connecting bolt. The support base also has multiple sets of bolt holes that mesh with the connecting bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model adopts a manual adjustment method with the cooperation of the adjusting screw and the locking nut, which does not require an additional power source. The tension can be adjusted by simply rotating the adjusting screw. It is simple to operate, can quickly respond to on-site adjustment needs, and solves the problem of time-consuming and laborious adjustment of traditional drums.

[0014] The overall structure is based on the support base, and the adjustment components and guide wheels are rigidly connected, which can withstand large tensile loads and is suitable for high-intensity working conditions during the traction process of the threading trolley;

[0015] The anti-derailment components on the guide wheel form a dual anti-derailment mechanism through the cooperation of protrusions, limit screws, and annular grooves, which can effectively prevent the wire rope from derailing. At the same time, the improved tension uniformity avoids risks such as derailment of the threading trolley and wire rope breakage, ensuring the safety of personnel and equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, this utility model discloses a wire rope tension adjustment device for a cable-driven trolley. The technical solution includes a support base 1, guide wheels 5, and tension wheels 7. The guide wheels 5 are rotatably connected to the support base 1, and there are two sets of guide wheels 5. The tension wheels 7 are connected to the support base 1 through an adjustment component and are located between the two sets of guide wheels 5. The support base 1 serves as a basic load-bearing component and is installed on the foundation frame to provide stable support for other components. The two sets of guide wheels 5 are symmetrically installed on the support base 1 by bolts and nuts, arranged in a straight line, and the center height of the groove of the guide wheel 5 is consistent with the height of the wire rope drum, ensuring that the wire rope 8 can be stably transmitted along a preset path.

[0023] like Figure 1 and Figure 3 As shown, under the action of the adjustment component, the tension wheel 7 is moved closer to or further away from the guide wheel 5, thereby adjusting the tension of the wire rope 8;

[0024] The adjustment assembly includes an adjustment screw 3 and a hinge seat 6. The support base 1 is slidably connected to the adjustment screw 3 via a support block 2. The adjustment screw 3 is locked and limited between itself and the support block 2 by a locking nut 4. The adjustment screw 3 is rotatably connected to the tension wheel 7 via the hinge seat 6.

[0025] The adjusting screw 3 is engaged with the locking nut 4, and there are two sets of locking nuts 4, which are symmetrically arranged on both sides of the support block 2.

[0026] like Figure 4 As shown, the guide wheel 5 is also provided with an anti-detachment component 9 to prevent the wire rope 8 from detaching from the wheel.

[0027] The anti-detachment component 9 is a U-shaped shell. The anti-detachment component 9 has a protrusion 12 and a limiting screw 13 on the side facing the guide wheel 5. The guide wheel 5 has an annular groove 14 corresponding to the position of the protrusion 12 and the limiting screw 13.

[0028] The protrusion 12 is hemispherical, and the opposing ends of the limiting screw 13 and the guide wheel 5 are rounded. The hemispherical protrusion 12 and the limiting screw 13 with rounded corners reduce the friction between them and the guide wheel 5.

[0029] On the other side of the anti-detachment component 9, there is a connecting block 15. The connecting block 15 is connected to the support base 1 by a connecting bolt 10. The support base 1 also has multiple sets of bolt holes 11 that mesh with the connecting bolt 10.

[0030] The working principle of this utility model:

[0031] The steel wire rope 8 is passed sequentially through the grooves on the same side of the two sets of guide wheels 5, and then through the inner groove of the tension wheel 7, forming a zigzag structure of "two guide wheels 5 winding outwards and tension wheel 7 winding inwards".

[0032] During tension adjustment, by changing the position of the adjusting screw 3 on the support block 2, the tension wheel 7 is moved closer to or further away from the guide wheel 5.

[0033] When the tension wheel 7 moves away from the guide wheel 5, the winding length of the wire rope 8 increases, the tension increases, and the tension increases.

[0034] When the tension wheel 7 approaches the guide wheel 5, the winding length of the wire rope 8 decreases, the tension decreases, and the tension decreases.

[0035] After adjustment, tighten the locking nuts 4 on both sides of the support block 2 to fix the adjusting screw 3, so as to prevent the tension wheel 7 from shifting due to the reaction force of the wire rope 8 and ensure tension stability.

[0036] The U-shaped housing of the anti-detachment component 9 encloses part of the guide wheel 5, and the hemispherical protrusion 12 on its inner side is embedded in the annular groove 14 of the guide wheel 5, forming the first limiting effect; the limiting screw 13 with rounded corners contacts the annular groove 14, forming the second limiting effect. The double limiting structure can effectively prevent the wire rope 8 from detaching from the groove of the guide wheel 5 during transmission or tension adjustment, ensuring safe operation.

[0037] The circuits and mechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. They are common knowledge.

[0038] Components not described in detail in this article are existing technologies.
