Description

Technical Field

[0001] The present invention relates to the field of fall arresters, in particular to an fall arrester guide rail diverter. Background Art

[0002] When workers climb ladders or equipment structures, they attach a fall arrester to a guide rail and connect it to a safety rope. If a dangerous fall occurs, the worker's own weight quickly locks the fall arrester into the guide rail, preventing the worker from falling. Existing guide rails for fall arresters come in multiple sizes. For example, existing power towers have multiple bends connecting longitudinal, transverse, and even diagonal rails. Due to the different load-bearing capacities in longitudinal and transverse directions, the guide rails used must be of varying strengths. For example, the web thicknesses of commercially available longitudinal and transverse rails are typically 6 mm and 8 mm, respectively. However, existing steering gears cannot accommodate steering between substandard guide rails. Therefore, both longitudinal and transverse guide rails typically use a single standard. Furthermore, existing steering gears experience significant wear between the guide rails and the gear, resulting in a short service life. Some steering gears utilize bearings, which can be too flexible and lack braking performance, leading to sluggish and unsmooth steering. Summary of the Invention

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below. The present invention will be further described below with reference to the accompanying drawings.

[0033] Example 1:

[0034] A fall-proof guide rail diverter comprises a base 1, a diverter member 2 and a docking strip, with four evenly arranged radial docking strips 5 integrally connected to the outer periphery of the base; a diverting groove 11 is provided in the base, and the diverting member is rotatably arranged in the diverting groove; the diverting member comprises a diverting rail 21, a turntable 22 and a rotating shaft 23, the turntable is vertically connected to the web of the diverting rail, the rotating shaft is provided on the side of the turntable facing away from the diverting rail and is coaxially arranged with the turntable, and after the diverting member rotates, the diverting rail 21 can correspond to the two docking strips arranged opposite to each other; a rotating hole 12 is provided in the center of the diverting groove, which passes through the rotating hole, and the protruding end is limited by a fixing member 4 detachably connected to the rotating shaft; the diverting groove is a circular groove, and the two ends of the diverting rail flange plate 211 of the diverting rail are arc-shaped end faces and match the inner wall of the circular groove, and an entrance and exit 111 are provided on the upper part of the groove wall of the diverting groove corresponding to the positions of the four docking strips.

[0035] The bottom of the steering groove is provided with a washer groove 112, in which a circular copper washer 6 is detachably provided. The upper end of the copper washer extends beyond the notch of the washer groove and abuts against the bottom of the turntable. A copper sleeve 7 is provided between the rotating shaft and the rotating hole.

[0036] The shaft is provided with an external thread, and the fixing member comprises a nut 41 threadedly connected to the shaft and a split pin 42 inserted at the end of the shaft. The above-mentioned shaft connection method is convenient and stable and is not easy to be disengaged.

[0037] The base of the steering gear of the present application is directly connected to the docking strip as a whole, and then connected to the guide rail by the docking strip, thereby avoiding the situation where the bending point is easily damaged by the connection through the connecting piece, and the connection strength between the steering gear and the guide rail can be improved. In addition, the present application can be rotated and positioned at the same time by directly coordinating the damping of the rotating shaft, the rotating hole, and the fixing part, thereby avoiding the problem of the bearing connection being too flexible. The turntable of the present application is a circular turntable with a large area and stable rotation, and the washer groove and the copper washer are matched to greatly reduce the friction between the turntable and the base pressed on the copper washer. Similarly, the setting of the copper sleeve can also reduce the corresponding friction and increase the service life of the device.

[0038] Example 2:

[0039] The difference from the above embodiment is that a steering limit arc groove 221 is formed on the edge of the turntable centered on the center of the turntable, and a limit stop 113 is provided on the inner edge of the steering groove. The cooperation between the arc-shaped steering limit arc groove and the limit stop not only effectively limits the rotation range of the steering rail, but also, due to the provision of the arc-shaped steering limit arc groove coaxial with the turntable, it also effectively guides the rotation of the turntable, making the steering more stable.

[0040] Example 3:

[0041] The difference from the above embodiment is that thickened triangular ribs 8 are provided on both sides of the connection position between the base and the docking strip, wherein the outer surfaces of the triangular ribs on both sides of a pair of opposing docking strips are arc-shaped surfaces 81, and the outer surfaces of the triangular ribs on both sides of the other pair of docking strips are flat surfaces 82. With two opposing docking strips as a group, the present application has at least two groups of docking strips, each group of which can be set with corresponding dimensions according to the different types of guide rails required, so that steering matching can be performed on guide rails of different models. For example, the steering gear can be connected to a T36*60*8 type guide rail horizontally and a T36*60*6 type guide rail vertically, which can achieve a material-saving setting while better meeting the strength requirements. Since the main difference between different types of guide rails is the thickness of the web, the steering gear installation error may occur because it is impossible to quickly distinguish the interface direction with the naked eye. The present application correspondingly designs the outer surfaces of the triangular rib blocks outside the steering gear into flat surfaces or curved surfaces for quick distinction. For example, the outer surfaces of the triangular rib blocks on both sides of one set of docking strips are flat surfaces, while the outer surfaces of the triangular rib blocks on both sides of another set of docking strips are curved surfaces, which makes it easier for operators to quickly distinguish and install them. It can also help aerial workers identify the guide rail model and choose whether to turn and change lanes at certain turning points.

[0042] Example 4:

[0043] The difference from the above embodiment is that the docking strip is a docking rail 51 or a docking groove strip 52, and both the docking rail and the docking groove strip are provided with a connection hole 53 that can be docked with the guide rail 90; and when the docking strip is a docking groove strip, the docking groove 521 on the docking groove strip is also provided with a secondary groove 522, and the lower end of the guide rail is embedded in the secondary groove. The docking strip of the present application can be a docking rail or a docking groove strip. When the docking strip is a docking rail, the hole in the docking strip can be directly connected to the guide rail through a connecting plate. When the docking strip is a docking groove, the rail guide rail can be directly inserted into the docking groove, and the secondary groove is used to cooperate with the web of the guide rail.

[0044] Embodiment 5:

[0045] The difference from the above embodiment is that an anti-drop device 9 is provided on the free end of the guide rail. The anti-drop device includes an anti-drop plate 91 hinged to the guide rail web, an extension 92 provided at the upper end of the anti-drop plate and facing the guide rail flange plate, a gravity block 93 provided on the extension, and a torsion spring 95 provided on the hinge shaft of the anti-drop plate. Through the above-mentioned gravity block device, the effective use of the anti-drop plate can still be guaranteed even if the torsion spring fails, thereby improving the safety of the anti-drop device. A brake hole 94 is provided on the side of the upper end of the anti-drop plate facing the extension. In order to facilitate the installation workers to descend the tower, a brake hole is designed on the right side of the anti-drop device. When the workers descend the tower, they can insert their fingers into the brake hole to rotate the anti-drop device, so that the anti-drop device can fall off smoothly.

[0046] Example 6:

[0047] The difference from the above embodiment is that the upper and lower butted guide rails are connected by a hole plate 96, and the ends of the guide rail flanges of the upper and lower butted guide rails are respectively provided with a flange concave stop 901 and a flange convex stop 902 that can be embedded, and the ends of the guide rail webs of the upper and lower butted guide rails are respectively provided with a web concave stop (903) and a web convex stop (904) that can be embedded. The web of the guide rail of the present application is provided with a connection hole, and then the upper and lower adjacent guide rails are connected by the hole plate and the connecting bolts provided on the hole plate and the guide rails. If the end faces are straight, the strength is limited and it is easy to bend or misalignment may occur during installation. However, the present application adopts the form of matching the flange concave stop 901 and the flange convex stop 902, and matching the web concave stop (903) and the web convex stop (904), thereby not only solving the problem of alignment but also greatly enhancing the connection strength and fit between the guide rails.

[0048] Embodiment seven:

[0049] The difference from the above embodiment is that at least two web convex stoppers (904) or two web concave stoppers (903) are provided on the web of the guide rail, and the web convex stoppers (904) provided on the same guide rail are of different lengths. The flange concave stoppers 901 and the flange convex stoppers 902 are respectively matched frustum-shaped concave stoppers and frustum-shaped convex stoppers, and the web convex stoppers are stepped convex stoppers with the outer end wider than the inner end. By setting the above-mentioned upper and lower concave stoppers of different depths and the convex stoppers of different lengths, the problem of weak strength caused by the end faces being easily bent in the same plane due to the same length can be reduced, thereby further improving the installation matching strength between the guide rails.

[0050] The steering gear of the present application is connected between the guide rails that need to be steered. For different types of guide rails, the docking strips and the guide rails can be installed and docked accordingly, and can be connected through orifice plates and bolts. An anti-drop device is set on the guide rail at the end. When in use, the anti-drop device is pulled outward around the hinge point, and then the anti-drop device 01 is inserted into the guide rail. When the anti-drop device moves to the steering gear, the steering gear can overcome the friction and rotate the steering rail to the required position, and then the anti-drop device slides onto the steering rail, and then the steering rail is rotated or not rotated as needed to move the anti-drop device to another guide rail.

[0051] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
