Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, specifically to a load-bearing steel wire rope end slippage indicator device. Background Technology

[0002] With socio-economic development, the requirements for construction safety are becoming increasingly stringent. During construction, various cantilevered construction tools (such as cantilevered unloading platforms and cantilevered scaffolding) frequently utilize wire ropes for stress relief. The wire ropes are typically bent 180 degrees at the ends and secured with rope clips. To prevent slippage under stress, a U-shaped bend is formed at the end. When the wire rope slips under stress, the height of the U-shaped bend decreases, alerting inspectors to take remedial measures. However, this method has drawbacks. When there are many wire ropes, recording the size of the U-shaped bend for each rope and determining whether it has changed is very difficult. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a load-bearing steel wire rope end slippage indicator device. This device can provide a clear signal as to whether the steel wire rope has slipped, providing a reliable basis for safety inspections and enabling inspectors to promptly identify potential safety hazards in the steel wire rope and take corresponding measures for inspection and handling.

[0004] A load-bearing steel wire rope end slip indication device includes a support structure, a vertical slider structure, and a horizontal sliding structure; the vertical slider structure is slidably connected to the support structure in the vertical direction, and the horizontal sliding structure is slidably connected to the support structure in the horizontal direction. The vertical slider structure includes a wedge-shaped block that is wider at the top and narrower at the bottom. The wedge-shaped block is in contact with the horizontal sliding structure for transmission. An indicator ball is temporarily fixed together with the horizontal sliding structure at the end of the support structure away from the vertical slider structure.

[0005] Preferably, the support structure includes an upper guide frame and a lower wire rope clamp. The side of the guide frame is provided with a vertical slot that cooperates with the vertical slider structure and a horizontal slot that cooperates with the horizontal sliding structure.

[0006] Preferably, the side of the wedge block is provided with a retaining strip that mates with the vertical slot.

[0007] Preferably, the wedge block is connected to a height-adjustable upper support.

[0008] Preferably, a connecting plate is provided above the wedge block, the connecting plate is provided with a vertical long groove, and the upper support is connected to the vertical long groove by screws and nuts.

[0009] Preferably, the horizontal sliding structure is driven by the contact between the roller and the wedge block.

[0010] Preferably, a reset mechanism is provided between the support structure and the horizontal sliding structure.

[0011] Preferably, the reset mechanism is a tension spring.

[0012] Preferably, the load-bearing steel wire rope end slip indicator device further includes a pad, which is disposed at the end of the horizontal sliding structure away from the roller, and a limit strip is provided at the upper end of the pad.

[0013] Preferably, the indicator ball is connected to the support structure via a connecting rope.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention places the top of the vertical slider structure in contact with the concave surface of the U-shaped bend of the wire rope. When the wire rope is overloaded and slips, the height of the U-shaped bend of the wire rope decreases, causing the vertical slider structure to move downward. Under the transmission action of the wedge block, the horizontal sliding structure moves horizontally, thus separating the end of the horizontal sliding structure from the support structure. When the separation distance reaches a certain limit, the indicator ball falls as a warning signal of wire rope slippage. Attached Figure Description

[0026] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0027] Example 1

[0028] like Figure 1-8 As shown, this utility model discloses a load-bearing steel wire rope end sliding indicator device, which includes four main parts: a support structure 9, a vertical slider structure 7, a horizontal sliding structure 6, and a pad 4.

[0029] The support structure 9 includes a split-type wire rope clip 9.7 fixed with screws, two connecting plates 9.1 installed above both ends of the wire rope clip 9.7, a guide frame 9.2 installed between the two connecting plates 9.1, a guide tube 9.3 installed at the other end of the guide frame 9.2, a first hook 9.4 installed on the side of the guide frame, a rope loop 9.5, and a spring hook 9.6. The connecting plate 9.1 is a horizontally placed U-shaped structure with a through groove running vertically through the interior. Vertical slots 9.2.1 are provided on the inner side of the two legs of the U-shaped structure near the closed end, allowing the vertical slider structure 7 to slide oriented within it. Horizontal slots 9.2.2 are provided along the extension direction of the two legs of the U-shaped structure, allowing the horizontal sliding structure 6 to slide oriented within it.

[0030] The vertical slider structure 7 includes a wedge block 7.2 and a connecting plate 7.1. The connecting plate has a C-shaped cross-section, and the upper support 13 is connected to the web of the C-shaped connecting plate by screws 11. The shape of the C-shaped connecting plate prevents the upper support from rotating. The C-shaped connecting plate has a vertical groove, which allows the upper support 13 to be adjusted within a certain range to accommodate different U-bend heights of the wire rope. The wedge block 7.2 has an inverted trapezoidal structure with an inclination angle of 45 degrees, which allows the vertical displacement of the vertical slider structure 7 to be converted into the horizontal displacement of the horizontal sliding structure 6 at a 1:1 ratio. Locking strips 7.3 are provided on both opposite sides of the C-shaped connecting plate. These locking strips are adapted to the vertical slots 9.2.1 of the support structure 9, allowing the vertical slider structure 7 to move in a directional manner.

[0031] The horizontal sliding structure 6 includes a roller 6.1, a U-shaped connecting plate 6.2 for mounting the roller 6.1, a screw 6.4 connected to the U-shaped connecting plate 6.2, and an extended screw 6.3 fixed to the side of the screw 6.4. The roller 6.1 reduces friction with the wedge block 7.2. The extended screw 6.3 engages with the horizontal slot 9.2.2 to allow the horizontal sliding structure 6 to move in a specific direction. A reset mechanism, preferably a tension spring 12, is provided between the spring hook 9.6 and the extended screw 6.3.

[0032] The pad 4 includes an end plate, a limiting strip 4.1 located on the side of the end plate, and a second hook 4.2 installed on the side of the limiting strip. The limiting strip 4.1 can restrict the pad 4 from rotating, and the second hook 4.2 corresponds to the first hook on the support structure 9, together squeezing the indicator ball 5.

[0033] When using, first fix the wire rope 1 with three rope clips 2 as specified. Then, when attaching the last rope clip 2, adjust the U-shaped bend of the wire rope to an appropriate height. Install the support structure 9 onto the main rope of the wire rope through the wire rope clips 9.7. When installing the vertical slider structure 7, adjust the position of the upper support 13 so that the tension spring 12 generates appropriate tension. Then, fix the two nuts 3 in sequence and clamp the pad 4. When tightening the outer nut, clamp the indicator ball 5 and the connecting rope 8 with the two hooks.

[0034] When the wire rope 1 slips due to overload, the height of the U-bend of the wire rope decreases, causing the vertical slider structure 7 to move downwards. The wedge block 7.2 then causes the horizontal sliding structure 6 and the pad 4 to move horizontally. This causes the second hook of the pad 4 to separate from the first hook 9.6 of the support structure 9. When the separation distance reaches a predetermined limit, the indicator ball 5 falls, issuing a warning signal. The diameter of the indicator ball 5 should be selected according to the allowable displacement limit. A lead ball with a relatively high specific gravity is preferred for the indicator ball 5.

[0035] When this device is used at an angle, a weight should be attached to the connecting rope of the shot put.

[0036] This device can provide a clear signal as to whether the wire rope has slipped, providing a reliable basis for safety inspections and enabling inspectors to promptly identify potential safety hazards in the wire rope and take appropriate measures to inspect and address them.

[0037] Example 2

[0038] In this embodiment, two hooks can be placed side by side, and an indicator ball 5 can be placed above the two hooks. The diameter of the indicator ball 5 is greater than the width of the hooks, but less than or equal to the width when the two hooks are joined together. When the two hooks are side by side, they can support the indicator ball 5. When the wire rope 1 is overloaded and slips, the height of the U-shaped bend of the wire rope decreases, causing the vertical slider structure 7 to move downward. The wedge block 7.2 causes the horizontal sliding structure 6 and the pad 4 to move horizontally, thus separating the second hook of the pad 4 from the first hook 9.6 of the support structure 9. The indicator ball falls between the two hooks, serving as a warning.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
