Detailed Implementation

[0040] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0041] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Throughout the text, the terms “top,” “bottom,” “above,” “below,” and “on top” refer to the relative positions of components of the device, such as the relative positions of the top and bottom substrates within the device. It is understood that the device is multifunctional and independent of its spatial orientation.

[0043] The working surface of this utility model can typically be a plane or a curved surface, and can be inclined or horizontal. For ease of explanation, the embodiment of this utility model is placed on a horizontal surface and used on a horizontal surface, thereby defining "height" and "vertical".

[0044] A specific embodiment of this utility model discloses a wire rope tensioning device, such as... Figures 1-3 As shown, it includes:

[0045] The support 1 is provided with an adjustment space 101, which includes at least a first enclosure 121 and a second enclosure 122 that are arranged opposite to each other.

[0046] The displacement rod 2 has one end passing through the first enclosure 121 and connected to the steel wire rope 5, and the other end passing through the second enclosure 122. The displacement rod 2 is configured to move relative to the support 1 in a set direction AA. The set direction is the length direction of the support 1, which is also the extension direction of the steel wire rope, i.e. the tensioning direction of the steel wire rope.

[0047] Fastener 3 is provided on the displacement rod 2. The fastener 3 is configured to be fixed in an adjustable position on the displacement rod 2, that is, the position of the fastener 3 on the displacement rod 2 is adjustable.

[0048] The elastic element 4 is sleeved on the displacement rod 2. One end of the elastic element 4 abuts against the first enclosure wall 121, and the other end of the elastic element 4 abuts against the fastener 3. That is, the elastic element 4 is located between the first enclosure wall 121 and the fastener 3.

[0049] The wire rope tensioning device is configured to adjust the rebound force of the elastic element 4 by adjusting the position of the fastener 3 on the displacement rod 2, so as to tension the wire rope.

[0050] It should be noted that the direction of the adjustment of the fastener 3 is opposite to the direction of movement of the displacement rod 2. That is, if the fastener 3 is adjusted towards the first enclosure wall 121, the rebound force of the elastic element increases, and the displacement rod 2 moves away from the first enclosure wall under the action of the rebound force, so that the wire rope is tightened. In other words, the increased length of the wire rope can be compensated by shortening the distance between the fastener and the wire rope.

[0051] When the wire rope 5 becomes longer during use, the displacement rod 2 moves away from the wire rope under the action of the elastic element 4, which increases the distance between the fastener 3 and the first enclosure 121 and reduces the rebound force of the elastic element 4. At this time, the fastener 3 is moved towards the first enclosure 121, thereby reducing the distance between the first enclosure and the fastener and increasing the rebound force of the elastic element 4, so that the wire rope is tightened.

[0052] The wire rope tensioning device of this utility model has a simple and reasonable structure and practical function. It is a safe and reliable device for tensioning wire ropes.

[0053] According to one embodiment of the present invention, the support 1 includes a connected base plate 11 and a surrounding frame 12, which together define the adjustment space 101. The length of the base plate 11 is greater than the length of the surrounding frame 12. Preferably, the surrounding frame 12 is located between the upper and lower ends of the base plate 11, that is, the two ends of the base plate 11 extend beyond the two ends of the surrounding frame 12. Specifically, the upper end of the base plate 11 is located above the upper end of the surrounding frame 12, and the lower end of the base plate 11 is located below the lower end of the surrounding frame, in order to improve the stability of the support 1.

[0054] To facilitate adjustment of the position of the fastener 3 on the displacement rod 2, the adjustment space 101 has at least two adjacent open sides. Preferably, the frame 12 is U-shaped, and includes a first wall 121 and a second wall 122 located at both ends, and a side plate 123 located between the first wall 121 and the second wall 122. The first wall 121 is located at the upper end, the second wall 122 is located at the lower end, and the side plate 123 is located on the right side. The rear ends of the first wall 121, the second wall 122, and the side plate 123 are respectively connected to the base plate 1, and the front and left sides of the frame are open.

[0055] To facilitate the movement of the displacement rod 2 along a predetermined direction, the first enclosure 121 has a first through hole through which the displacement rod 2 passes, and the second enclosure 122 has a second through hole through which the displacement rod 2 passes. The first and second through holes are positioned opposite each other, allowing the displacement rod 2 to move up and down relative to the support 1 via the first and second through holes. To ensure smooth movement of the displacement rod 2, the diameters of both the first and second through holes are not less than the diameter of the displacement rod 2. However, to ensure the stability of the displacement rod 2's movement, the diameters of both the first and second through holes are not greater than 1.1 times the diameter of the displacement rod 2.

[0056] Preferably, the base plate 11 and the frame 12 are integrally formed or connected by welding to ensure the structural strength and stability of the support.

[0057] The base plate 11 has multiple mounting holes 111 for detachably fixing the wire rope tensioning device. When the wire rope tensioning device no longer tensions the wire rope at a certain position, it can be disassembled and moved to another position to restore its tensioning function. In this embodiment, the base plate 11 has four mounting holes along its extension direction, and at least two mounting holes are located on the outer sides of both ends of the frame, that is, at least one mounting hole is located on the top of the frame and at least one mounting hole is located on the bottom of the frame.

[0058] To protect the structure within the adjustment space and prevent foreign objects from accidentally entering and affecting the operation of the wire rope tensioning device, the wire rope tensioning device also includes a protective shell 6, which covers the assembly space 101 and is detachably connected to the bracket 1, allowing for easy removal of the protective shell to adjust the position of the fastener 3. The rear end of the protective shell 6 abuts against the front sidewall of the base plate 11. The protective shell 6 can at least completely cover the frame 12, blocking all open surfaces of the frame 12 and preventing any part of the adjustment space from being exposed. Preferably, the shape of the protective shell 6 is adapted to the shape of the frame 12 to improve the structural compactness and stability of the wire rope tensioning device. To prevent the protective shell 6 from affecting the movement of the displacement rod 2, the protective shell 6 is provided with a U-shaped hole (not shown in the figure) at the position opposite to the first enclosure wall and the second enclosure wall for the displacement rod 2 to pass through. That is, the top wall and bottom wall of the protective shell 6 are provided with U-shaped holes with the opening facing backward. The U-shaped hole is adapted to the displacement rod, that is, the width of the U-shaped hole is not less than the diameter of the displacement rod 2, so that the displacement rod 2 can enter the U-shaped hole along the opening of the U-shaped hole.

[0059] For example, the top and bottom walls of the protective shell 6 are respectively connected to the first enclosure wall 121 and the second enclosure wall 122 by threaded connections. That is, at least one threaded hole is provided on the top wall at the position corresponding to the first enclosure wall, and at least one threaded hole is provided on the bottom wall at the position corresponding to the second enclosure wall. Screws or bolts pass through the corresponding threaded holes for fixing, so that the protective shell 6 can be detachably installed on the bracket 1. In practical applications, the protective shell and the bracket can also be detachably connected by snap-fit, magnetic attraction, or other detachable connection methods.

[0060] To intuitively understand the state of the wire rope (e.g., whether its length has been stretched, its tension, etc.), the wire rope tensioning device also includes an indicator component, which includes:

[0061] An indicator window 601 is provided on the protective shell 6, preferably located on the front end face of the protective shell 6, for observation purposes;

[0062] The pointer 7 is located between the elastic element 4 and the fastener 3, and the other end is exposed through the indicator window 601 so that the position of the pointer 7 can be observed from the outside, thereby knowing the position of the fastener 3, and thus knowing the length of the elastic element 4 at this time, and knowing the length of the steel wire rope that has been stretched.

[0063] The indicator window 601 extends along a set direction AA, and the width of the indicator window 601 is adapted to the width of the pointer 7, so that the pointer 7 can move stably along the extension direction of the indicator window.

[0064] The pointer 7 includes a collar and a needle. One end of the needle is connected to the collar, and the other end of the needle protrudes through the indicator window 601. The collar is sleeved on the displacement rod and is located between the elastic member 4 and the fastener 3. That is, the collar moves with the fastener, thereby driving the needle to move within the indicator window 601. The position of the fastener 3 can then be deduced by observing the position of the needle in the indicator window from the outside.

[0065] The closer the pointer is to the first wall, the better the tension of the wire rope; conversely, the closer the pointer is to the second wall, the longer the wire rope has been stretched and the worse the tension.

[0066] Preferably, an indicator area 602 is provided on the outer side of the indicator window 601. The indicator area 602 has different color zones along the length direction (i.e., the extension direction) of the indicator window to more intuitively and significantly indicate the state of the wire rope. For example, the indicator area has a green area, a yellow area, and a red area sequentially along the length direction of the indicator window, with the green area closer to the direction where the first enclosure wall is located. When the pointer is in the green area, it indicates that the wire rope is in a good tension state; when the pointer is in the yellow area, it indicates that the wire rope has been stretched and the tension state has deteriorated; when the pointer is in the red area, it indicates that the wire rope has been stretched even longer and the tension state is even worse, requiring timely adjustment of the fasteners.

[0067] To protect the connection stability of the bracket 1, elastic element 4, pointer 7 and fastener 4, a first gasket is provided between the first enclosure 121 and the elastic element 4, a second gasket is provided between the elastic element 4 and the pointer 7, and a third gasket is provided between the pointer 7 and the fastener 3. These gaskets are not shown in the attached drawings.

[0068] To prevent the end of the displacement rod 2 (the end furthest from the wire rope) from dislodging from the through hole in the second enclosure 122, a limiting member 8 is provided at the end of the displacement rod 2. The diameter of the limiting member 8 is larger than the diameter of the through hole in the second enclosure 122. Preferably, the limiting member 8 is detachably provided at the end of the displacement rod 2 to facilitate the assembly and maintenance of the wire rope tensioning device.

[0069] According to a preferred embodiment of this utility model, the displacement rod 2 is a lifting eye bolt, which includes a ring portion 21 and a threaded portion 22. One end of the threaded portion 22 is provided with the ring portion 21, and the other end of the threaded portion 22 passes through the first enclosure wall 121 and the second enclosure wall 122 in sequence. The fastener 3 includes two hexagonal nuts, which are continuously installed on the threaded portion 22 to prevent loosening. The elastic element 4 is a compression spring, which is sleeved on the threaded portion 22 and located within the adjustment space (i.e., between the first enclosure wall and the fastener). The limiting element 8 is a locking nut, which is fixed to the end of the threaded portion (the end away from the ring portion).

[0070] The method of using this utility model is as follows: First, fix the bracket 1 in a position that can tighten the wire rope, and connect the wire rope to the displacement rod 2 (i.e., the ring 21); then, the end of the displacement rod 2 (the end away from the wire rope) passes through the first enclosure 121 from top to bottom and enters the adjustment space 101; then, the end of the screw part 22 passes through the first washer, the elastic member 4, the second washer, the pointer 7, the third washer and the fastener 3 in sequence, and then passes through the second enclosure 122, and is fixed by the limiting member 8. Preferably, the length of the end of the screw part protruding from the limiting member (i.e., the distance between the lower end face of the screw part and the limiting member) is 6-10mm; finally, tighten the wire rope by adjusting the position of the fastener 3, place the protective cover 6 on the enclosure 2 and make the pointer pass through the indicator window 601 at the same time, at which time the pointer is located in the green area. When the wire rope is in use, and the pointer is in the yellow or red area, the protective cover needs to be removed and the position of fastener 3 adjusted so that the wire rope is tightened again. Then, the protective cover is fastened back, and the pointer returns to the green area.

[0071] When the wire rope can no longer be tightened by adjusting the fastener 3, the bracket 1 needs to be removed from its original position and moved to a position where the wire rope can continue to be tightened. It should be noted that after the bracket is moved, the position of the fastener 3 needs to be readjusted.

[0072] The wire rope tensioning device of this invention can be used in any location where wire rope tensioning is required, especially at one end of the wire rope on a climbing ladder, to ensure that workers can keep the wire rope in the optimal tension state at all times through the wire rope tensioning device.

[0073] This utility model discloses a wire rope tensioning device that can maintain the wire rope in a taut state during use, ensuring its functionality and safety. The device has a reasonable structure, is easy to install, practical in function, and safe and reliable. Compared with existing designs on the market, it represents a significant improvement and is worthy of widespread promotion and application.

[0074] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
