Description

Technical Field

[0001] This invention belongs to the technical field of high-altitude work protection equipment, specifically relating to a variable-direction load sliding guide device. Background Technology

[0002] In scenarios such as working at heights, working on slopes, equipment maintenance, and personnel assisted traction, guiding devices are usually required to enable personnel, tools, or loads to move along a predetermined path. Existing guiding devices mostly use rigid guide rails, sliding cables, wire ropes, or other linear load-bearing components as the guiding foundation, and then configure sliding trolleys, hooks, or moving connectors on them to achieve load sliding, traction, or safety protection.

[0003] Existing structures using steel wire ropes as guide foundations typically require end supports or intermediate supports to fix and support the steel wire ropes. When the guide path is long, has a bend or turns, or needs to bypass obstacles, multiple supports are often needed along the path to maintain the position and tension of the steel wire rope. However, existing intermediate supports are mostly fixed structures, with a relatively fixed connection direction between the support and the steel wire rope. When the trolley is affected by personnel pulling, load swaying, or changes in external forces, the direction of force on the trolley can easily be inconsistent with the guide direction of the support. This can cause the trolley to deviate, be squeezed, or get stuck when approaching or passing the intermediate support, affecting the stability of continuous sliding.

[0004] Meanwhile, the existing connection structure between the sliding trolley and the wire rope typically uses single-sided rollers, hook-type pulleys, or open-type wheel assemblies. While this type of structure can achieve basic sliding, its ability to contain and limit the wire rope is insufficient. When the load direction changes, the wire rope partially turns, or the sliding trolley swings, there is a risk that the rollers may deviate from the wire rope, the sliding may be uneven, or the rope may even come off. If a closed limiting structure is added to improve the anti-derailment capability, it may prevent the sliding trolley from passing the intermediate support, or it may require the load to be released, the wire rope to be disconnected, or manual transfer to be performed before passing the support, reducing the continuous usability of the guiding device.

[0005] For end-guided sliding devices, the sliding trolley typically requires a steel cable to be inserted from the end of the guide line. If the existing end structure is completely open, the sliding trolley may detach from the steel cable end during use due to misoperation, impact, or reverse slippage. If the end uses a fixed, enclosed structure, it increases the difficulty of installing, disassembling, and maintaining the sliding trolley. Therefore, there remains a certain contradiction between the ease of end assembly and the safety of preventing detachment in existing guiding devices. Summary of the Invention

[0006] The purpose of this invention is to provide a variable load sliding guide device to improve the problem that the sliding trolley cannot move and pass through the support when the load is skewed or the force direction changes, while taking into account the convenience of loading the end of the sliding trolley and the safety of preventing it from falling off during use.

[0007] This invention provides a variable-direction load sliding guide device, comprising a guide line component, a sliding trolley, and a reversing support; the reversing support includes a fixed bracket and a tilting bracket. The tilting bracket includes a rotating connecting part, a connecting plate, and a transition guide sleeve connected in sequence. The rotating connecting part is rotatably connected to the fixed bracket; the transition guide sleeve is connected to the guide line component.

[0008] The sliding trolley includes a sliding bracket, a traveling roller assembly mounted on the sliding bracket, and a load-bearing connection. The traveling roller assembly forms a guide channel through which the guide line passes and is provided with a clearance for the sliding trolley to avoid the connecting plate when passing the reversing support. The tilting bracket rotates in the direction of the tension provided by the sliding trolley, so that the connecting plate and the clearance remain in a positional matching state.

[0009] Preferably, the reversing support further includes a hinge shaft. The hinge shaft is disposed on the fixed bracket; the rotating connection part is a sleeve structure sleeved on the hinge shaft.

[0010] Preferably, at least one end of the transition guide sleeve is provided with an inlet section, the outer diameter of which gradually decreases in the direction away from the center of the transition guide sleeve.

[0011] Preferably, there are multiple directional support brackets, including two end directional support brackets and one or more intermediate directional support brackets arranged between the two end directional support brackets; the guide line passes through the multiple directional support brackets in sequence; the end directional support brackets are provided with openable end limiting members, which are used to allow the sliding trolley to be loaded into the guide line in the open state; and to prevent the sliding trolley from disengaging from the end of the guide line in the closed state.

[0012] Preferably, the end limiting member includes a stop plate and an elastic member, the stop plate being movably connected to the flipping bracket, and the elastic member applying an elastic clamping force to the stop plate toward the flipping bracket.

[0013] Preferably, the elastic element is a C-shaped coil spring, which is sleeved on the outside of the sleeve of the flip bracket and cooperates with the stop plate so that the stop plate presses against the flip bracket under normal conditions.

[0014] Preferably, the traveling roller assembly includes an integral roller structure and a split roller structure, wherein the integral roller structure and the split roller structure together form the guide channel, and the clearance is formed in the split roller structure.

[0015] Preferably, the integral roller structure includes a first axle and a first roller. The first axle is mounted on the sliding bracket, and the first roller is mounted on the first axle. The outer circumferential surface of the first roller has a first groove. The split roller structure includes two relatively spaced single-sided roller structures, each including a second axle and a second roller. The second axle is mounted on the sliding bracket; the second roller is mounted on the second axle. A clearance gap is formed between the two opposing second rollers. The outer circumferential edge of the second roller has a second groove that mates with the first groove to form a guide channel.

[0016] Preferably, the distance between the groove edge of the first roller and the groove edge of the second roller is less than the diameter of the guide wire, and the distance between the two second rollers is greater than the thickness of the connecting plate and less than the diameter of the guide wire.

[0017] Preferably, the guide wire is a steel wire rope, and the end of the steel wire rope is provided with a pressing rope clamp.

[0018] Preferably, the sliding support includes two side plates that are spaced apart from each other; the walking roller assembly is disposed between the two side plates.

[0019] The present invention has the following beneficial effects.

[0020] 1. This invention achieves the effect of the directional support rotating synchronously with the direction of force on the sliding trolley by setting a rotatable flipping bracket and connecting the transition guide sleeve to the wire rope. This allows the sliding trolley to maintain stable guidance when the load is skewed or the direction of force changes, reducing the risk of jamming when passing through the intermediate support.

[0021] 2. This invention, by incorporating both an integral roller structure and a separate roller structure on the sliding trolley, creates a guide channel for the wire rope, achieving a containment-type rolling limit effect on the wire rope. This prevents the sliding trolley from detaching from the rope under load and allows it to slide smoothly along the wire rope. Simultaneously, by creating a clearance gap between the two second rollers of the separate roller structure, and ensuring this clearance gap avoids the connecting plate of the intermediate deflector support, this invention allows the sliding trolley to pass over the intermediate deflector support without disconnecting the wire rope or removing the load, thus improving continuous sliding guidance capability.

[0022] 3. By setting introduction sections with gradually changing outer diameters at both ends of the transition guide sleeve, the present invention achieves the effect of smooth introduction and transition of the traveling roller assembly, thereby reducing the impact, jumping and jamming when the sliding trolley approaches or passes the turning support, and improving the stability of the load sliding process.

[0023] 4. This invention achieves a continuous guide line structure by sequentially passing the wire rope through multiple directional supports and fixing its ends with compression rope clamps. This allows the wire rope to perform both guiding and load-bearing functions, reducing the need for additional rigid rails and improving the device's adaptability to installation on straight, broken, or spatial curved paths.

[0024] 5. This invention achieves the effect of opening the end entrance of the guide line structure and automatically resetting and closing by setting a stop plate on the end reversing support and using a C-shaped spring to apply elastic clamping force to the stop plate. This facilitates the loading of the steel wire rope into the sliding trolley and prevents the sliding trolley from accidentally sliding out of the end of the steel wire rope after loading, thereby improving the safety and ease of assembly.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] Example

[0035] like Figure 1 As shown, this embodiment provides a variable-direction load sliding guide device, including a reversing support 100, a wire rope 200, a sliding trolley 300, and a pressing rope clamp 400. Multiple reversing supports 100 are arranged sequentially at intervals. Each reversing support 100 includes two end reversing supports 110 located at both ends, and one or more intermediate reversing supports 120 located in the middle. In this embodiment, the number of reversing supports 100 is three: one intermediate reversing support 120 and two end reversing supports 110.

[0036] The wire rope 200 passes sequentially through each deflector support 100, forming a complete guide line structure. Two end deflector supports 110 are respectively located at the ends of the guide line structure; the intermediate deflector support 120 is located in the middle of the guide line structure. Two compression rope clamps 400 are respectively fixedly installed at both ends of the wire rope 200 to compress and fix the ends of the wire rope 200, ensuring the structural stability of the wire rope 200. The sliding trolley 300 is threaded onto the wire rope 200 and can slide along the wire rope 200.

[0037] like Figure 2 and Figure 3As shown, both the end reversing support 110 and the intermediate reversing support 120 include a fixed bracket 130, a hinge shaft 140, and a flipping bracket 150. The fixed bracket 130 is locked and fixed to the external frame structure by bolts, washers, and nuts, ensuring the stable position of the fixed bracket 130. The fixed bracket 130 adopts a bent plate structure. The hinge shaft 140 passes through and is fixed to the fixed bracket 130. The flipping bracket 150 includes a rotating connecting part 151, a connecting plate 152, and a transition guide sleeve 153. The two side edges of the connecting plate 152 are fixed to the rotating connecting part 151 and the transition guide sleeve 153, respectively. The rotating connecting part 151 adopts a sleeve structure and is sleeved on the corresponding hinge shaft 140 to form a rotating connection. The transition guide sleeve 153 is sleeved on the wire rope 200 and fixed to the wire rope 200.

[0038] Both ends of the transition guide sleeve 153 are provided with inlet sections 154. The outer diameter of the inlet section 154 gradually decreases in the direction away from the middle of the transition guide sleeve 153. In some embodiments, the outer surface of the inlet section 154 is an inclined surface, an arc surface, a curved surface, or a surface with a gradually changing outer diameter, so that the sliding trolley 300 can smoothly enter the middle receiving section of the transition guide sleeve 153 when it approaches the transition guide sleeve 153, reducing the risk of jamming.

[0039] In some embodiments, such as Figure 2 and Figure 7 As shown, the end reversing support 110 further includes a stop plate 160 and a C-coil spring 170. The stop plate 160 is movably connected to the flipping bracket 150; the C-coil spring 170 cooperates with the stop plate 160 and applies an elastic clamping force towards the flipping bracket 150 to the stop plate 160, so that the stop plate 160 is pressed against the side of the flipping bracket 150 under normal conditions. In some embodiments, the C-coil spring 170 is sleeved on the outside of the rotating connection portion 151. The stop plate 160 is fixed to one side of the C-coil spring 170.

[0040] In some further embodiments, one side of the stop plate 160 is provided with a C-shaped outer sleeve structure that is fitted over the outside of the rotating connection portion 151. The other side of the stop plate 160 is provided with a gripping structure. The gripping structure is a bent and flanged structure. The C-shaped coil spring 170 is fitted over the outside of the C-shaped outer sleeve structure of the stop plate 160, with one edge of the notch abutting against the side of the stop plate 160 away from the connecting plate 152, and the other edge of the notch abutting against the side of the connecting plate 152 away from the stop plate 160.

[0041] When it is necessary to load the sliding trolley 300 into the wire rope 200, manually open the stop plate 160 or the C-coil spring 170 to separate the stop plate 160 from the tilting bracket 150, preventing the stop plate 160 from blocking the sliding trolley 300 from entering the guide line structure. After the sliding trolley 300 enters the guide line structure, release the stop plate 160 and the C-coil spring 170. Under the elastic action of the C-coil spring 170, the stop plate 160 presses against the side of the tilting bracket 150 again, thereby closing the end inlet and preventing the sliding trolley 300 from sliding out of the end of the wire rope 200.

[0042] In other embodiments, other detachable limiting structures can be used instead of the stop plate 160 and the C-coil spring 170. For example, a limiting screw is threaded onto the connecting plate 152 of the flip bracket 150. The position of the limiting screw is aligned with the sliding bracket 310 of the sliding trolley 300 along the axis of the wire rope 200. When the limiting screw is removed, the sliding trolley 300 can pass over the connecting plate 152 on the end reversing support 110. When the limiting screw is installed, the sliding trolley 300 is blocked by the limiting screw and cannot pass over the connecting plate 152 on the end reversing support 110.

[0043] like Figure 4 and Figure 5 As shown, the sliding trolley 300 includes a sliding support 310, a traveling roller assembly 320, and a load connection part 330. The sliding support 310 includes two side plates arranged at relatively intervals. An installation space is formed between the two side plates for the steel wire rope 200 to pass through. The load connection part 330 is fixed to the end of the sliding support 310. The load connection part 330 is used to connect a safety rope. The safety rope is connected to the worker, providing protection and auxiliary pulling force for the worker.

[0044] The load connection 330 can be a connection hole, a hanging hole, a connecting shaft, or a hanger. After the operator connects to the load connection 330 of the sliding trolley 300 via a safety rope, the load force is concentrated on the lower part of the sliding trolley 300. Combined with the tilting brackets 150 on each directional support 100 that can swing in the direction of force, the sliding trolley 300 maintains its sliding guiding ability even under load. Simultaneously, the tilting brackets 150, which swing with the trolley, will always remain aligned with the clearance 370 on the sliding trolley 300. Therefore, under different force directions, the clearance 370 on the sliding trolley 300 can always pass over the intermediate directional support 120.

[0045] Multiple traveling roller assemblies 320 are disposed between two side plates and arranged in a straight line. The traveling roller assemblies 320 are used to form a movable connection with the wire rope 200, so that the sliding trolley 300 can move along the wire rope 200 under load and can pass over the intermediate turning support 120.

[0046] In this embodiment, the side plate has a V-shaped structure. The load connection part 330 is located at the tip of the V-shape. There are two traveling roller assemblies 320. The two traveling roller assemblies 320 are symmetrically arranged on both sides of the center line of the V-shaped side plate.

[0047] The traveling roller assembly 320 includes an integral roller structure 340 and a split roller structure 350. The groove structures on the integral roller structure 340 and the split roller structure 350 together form a guide channel 360 for the wire rope 200. The wire rope 200 passes through the guide channel 360 and is movablely limited by the traveling roller assembly 320. The split roller structure 350 is provided with a gap structure, allowing the split roller structure 350 to pass over the connecting plate 152 on the tilting bracket 150.

[0048] The integral roller structure 340 includes a first axle 341 and a first roller 342. The first axle 341 is laterally connected between two side plates. Both ends of the first axle 341 are fixed to the two side plates by nuts. The first roller 342 is rotatably connected to the first axle 341 via two first bearings 343. The inner rings of the two first bearings 343 are axially positioned between each other, and between the inner rings of the first bearings 343 and the inner surfaces of the side plates, by first bushings. A concave first groove 344 is provided on the outer circumferential surface of the first roller 342.

[0049] The split roller structure 350 includes two symmetrically spaced single-sided wheel structures 351. Each single-sided wheel structure 351 includes a second wheel axle 352 and a second roller 353. The two second wheel axles 352 are respectively mounted on two side plates and extend towards the mounting space between the two side plates; the two second wheel axles 352 are aligned and spaced apart. A first annular protrusion 355 is provided on the outer peripheral surface of the opposite ends of the two second wheel axles 352. The first annular protrusion 355 forms a limiting shoulder at the end of the second wheel axle 352.

[0050] Two second rollers 353 are rotatably connected to the opposite ends of two second wheel shafts 352 via second bearings 354. The inner ring of the second bearing 354 is limited by a limiting shoulder at the end of the second wheel shaft 352. A second bushing for axial limiting is provided between the inner ring of the second bearing 354 and the inner side of the side plate.

[0051] Each of the two second rollers 353 has a second annular protrusion 356 at its opposite end of the center hole. The second annular protrusion 356 forms a limiting stepped surface on the center hole of the second roller 353 that mates with the outer ring of the second bearing 354. The limiting stepped surfaces of the two second rollers 353 are located between the outer rings of the two second bearings 354, preventing the distance between the second rollers 353 from increasing.

[0052] Two second rollers 353 are arranged at a distance from each other, forming a clearance 370 between the two second rollers 353. The clearance 370 is used to avoid the connecting plate 152 on the intermediate deflector support 120 when the sliding trolley 300 passes the intermediate deflector support 120.

[0053] Each of the two second rollers 353 has a recessed second groove 357 on its outer peripheral edge at the opposite ends. The second groove 357 faces the center of the guide channel 360 formed by the integral roller structure 340 and the split roller structure 350. The second grooves 357 on the two second rollers 353 are aligned with the left and right sides of the first groove 344 on the first roller 342, respectively.

[0054] The distance between the groove edge of the first roller 342 and the groove edge of the second roller 353 is less than the diameter of the wire rope 200; the distance between the two second rollers 353 is greater than the thickness of the connecting plate 152 and less than the diameter of the wire rope 200, so that the wire rope 200 is stably constrained in the guide channel 360, and the connecting plate 152 can pass through the clearance gap 370 between the two second rollers 353. The diameter of the guide channel 360 is equal to or slightly larger than the outer diameter of the transition guide sleeve 153, so that the traveling roller assembly 320 can smoothly pass over the transition guide sleeve 153 sleeved and fixed on the wire rope 200.

[0055] The axial cross-sections of the first wheel groove 344 and the second wheel groove 357 are both arc-shaped, which allows the roller to form an arc-edge contact with the wire rope 200. This enables the wire rope 200 to be guided in an enclosed manner even when the force direction of the sliding trolley 300 changes. As a result, the wire rope 200 is less likely to fall out of the guide channel 360.

[0056] In this embodiment, to ensure that the gliding trolley 300 can glide stably under uncertain force directions and is not blocked by the intermediate directional support 120 when passing through it, both the end directional support 110 and the intermediate directional support 120 in this embodiment are designed to be rotatable. When the gliding trolley 300 is subjected to forces in different directions, the flipping bracket 150 on the directional support 100 can rotate synchronously with the gliding trolley 300, thereby ensuring that the gliding trolley 300 passes through the intermediate directional support 120.

[0057] In some embodiments, the wire rope 200 is kept taut between each deflection support 100, so that the guide line structure has a continuous guiding reference. When the trolley 300 moves along the wire rope 200, the wire rope 200 simultaneously undertakes the guiding and load-bearing functions, which can reduce the setting of additional track structures, making the device structure simpler and more adaptable to installation.

[0058] In some embodiments, multiple directional supports 100 are arranged along a straight line, a broken line, or a spatial curve, so that the wire rope 200 forms a corresponding guide path. Since each directional support 100 can rotate with the direction of force, the sliding trolley 300 can maintain its engagement with the wire rope 200 under different spatial postures, thereby adapting to usage scenarios with large changes in load direction.

[0059] In some embodiments, a bushing, a bushing, or a wear-resistant washer is provided between the rotating connection 151 and the hinge shaft 140 to reduce wear when the flip bracket 150 rotates around the hinge shaft 140 and to improve the stability of the flip bracket 150 rotation.

[0060] In some other embodiments, the hinge 140 is a pin, bolt, stepped shaft, or pivot with a limiting head. The hinge 140 can be limited on the fixed bracket 130 by a nut, cotter pin, snap ring, or end cap.

[0061] like Figure 6 and Figure 7 As shown, the working process of the variable load sliding guide device provided in this embodiment is as follows:

[0062] First, the wire rope 200 is connected to the end reversing support 110 and the intermediate reversing support 120 to form a guide line structure, and the end of the wire rope 200 is fixed by the pressing rope clamp 400. Then, the sliding trolley 300 is threaded onto the wire rope 200, allowing the sliding trolley 300 to slide along the wire rope 200. After the worker connects to the sliding trolley 300, the sliding operation begins.

[0063] During the gliding process, if the direction of force on the worker or load changes, the gliding trolley 300 will swing accordingly. Since both the end reversing support 110 and the intermediate reversing support 120 are rotatable, the flipping bracket 150 on the reversing support 100 can rotate synchronously with the direction of force. When the gliding trolley 300 passes the intermediate reversing support 120, the flipping bracket 150 and the clearance 370 on the gliding trolley 300 remain aligned, allowing the gliding trolley 300 to easily glide past the intermediate reversing support 120 under load.

[0064] As the trolley 300 passes the intermediate deflector support 120, the introduction section 154 of the transition guide sleeve 153 first guides the traveling roller assembly 320, and the clearance 370 of the split roller structure 350 then avoids the connecting plate 152 on the tilting bracket 150. During this process, the integral roller structure 340 continuously forms a rolling engagement with the wire rope 200 or the transition guide sleeve 153, thus ensuring that the trolley 300 maintains load-bearing and guiding capabilities while passing the intermediate deflector support 120.

[0065] By utilizing the combination of the flip-up bracket 150, the transition guide sleeve 153, the split roller structure 350, and the load connection part 330, this embodiment solves the problem that the sliding trolley 300 has difficulty passing through the intermediate support when the load is skewed. Even if the load direction changes, the flip-up bracket 150 can rotate synchronously with the sliding trolley 300, ensuring that the clearance 370 corresponds to the connecting plate 152, thereby reducing the risk of jamming.
