Description

Technical Field

[0001] This invention relates to the field of rope and locking technology, and more specifically, to a fall arrest rope assembly for large tools used in high-altitude operations. Background Technology

[0002] When performing work at heights (such as transformer maintenance, meter replacement, and pipeline replacement), many large tools are required. Due to the small area and high height of the work platform, large tools should not be left on the platform after use, otherwise they may fall from the height and cause safety hazards.

[0003] In existing technologies, to prevent the risk of falling, large workpiece transfer tools are used to transfer the workpiece. However, the transfer of large tools affects work efficiency and reduces overall work efficiency. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing technologies that require the constant transfer of large tools during high-altitude operations, which reduces the efficiency of high-altitude work. It provides a fall protection and fixing rope assembly for large tools used in high-altitude operations. One end of the assembly can be easily fixed to the high-altitude work platform, and the other end can be easily connected to large tools. This allows large tools to be easily and stably suspended on the high-altitude platform, eliminating the trouble of frequently transferring large tools and improving the efficiency of high-altitude operations.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fall protection and fixing rope assembly for large tools used in high-altitude operations, comprising:

[0006] The locking block has an opening slot, and a sealing component is provided at the opening of the opening slot to close the opening slot.

[0007] The connecting rope is fixedly connected to the locking block.

[0008] In this invention, the connecting rope is placed into the open slot, so that both ends of the connecting rope form annular loops. One end of the loop is fitted onto a high platform, and the other end is fitted onto a large tool, allowing the large tool to be suspended on the high platform. Because the loop is a movable loop that can change size, the loop can automatically shrink and tighten around the large tool due to the weight of the large tool itself. Through the above design, one end can be easily connected to the large tool, and the other end can be easily and stably connected to the high platform, eliminating the trouble of frequently transferring large tools and improving the efficiency of high-altitude operations.

[0009] Preferably, the two sides of the opening slot are a first fixing plate and a second fixing plate, respectively. The first fixing plate is provided with a through slot, and the second fixing plate is provided with an abutment slot that mates with the through slot. A limiting hole is provided through the side wall of the abutment slot. The sealing assembly includes a sealing plate and a limiting pin. The sealing plate passes through the through slot and abuts with the abutment slot. The sealing plate is provided with a limiting slot that mates with the limiting hole. The limiting pin is provided in the limiting hole. A pushing member is provided in the limiting hole to push the limiting pin to move toward the limiting slot. The pushing member pushes the end of the limiting pin to abut with the limiting slot.

[0010] The above-described design allows for easy opening of the slot to facilitate inserting the connecting rope into it; it also allows for easy removal of the connecting rope from the slot when needed.

[0011] Preferably, there are two limiting grooves in the width direction of the sealing plate, and two limiting holes are provided on the side wall of the abutment groove. Two limiting pins are inserted into the limiting holes, and the two limiting pins are connected by a connecting plate at the end away from the sealing plate.

[0012] The system uses two limit pins and limit holes to work together to better limit the sealing plate. At the same time, by using a connecting plate, pulling the connecting plate can simultaneously move the two limit pins, making it easy to lock or open the sealing plate.

[0013] Preferably, the width of the through groove gradually increases outwards from the end furthest from the opening groove. This gradually increasing width of the through groove facilitates the insertion of the sealing plate.

[0014] Preferably, the end of the sealing plate away from the abutment groove is a pinch plate.

[0015] The gripper design makes it easy to remove the sealing plate from the through slot.

[0016] Preferably, a mounting groove is provided in the circumferential direction of the inner sidewall of the limiting hole, an abutment ring is fixedly provided in the circumferential direction of the limiting pin, and the pushing component is a pushing spring, which abuts against the end of the mounting groove and the abutment ring.

[0017] By setting a push spring, which pushes the limit pin, the sealing plate can be automatically locked.

[0018] Preferably, a first roller and a second roller are respectively embedded in the two side walls of the opening groove. The first roller and the second roller are symmetrically arranged and rotate synchronously in opposite directions. Both the first roller and the second roller are rollers with varying radii. An adjusting nut is fixedly connected to the end of the first roller. A locking nut is provided at the end of the second roller to control its rotation.

[0019] An adjusting nut is fixedly connected to the end of the first roller. Rotating the adjusting nut allows adjustment of the angle between the first and second rollers, thus adjusting the gap between them. A locking nut is provided at the end of the second roller to control its rotation. Rotating the locking nut locks the first and second rollers. This allows the annular sleeve formed by the connecting rope to be configured as a fixed or movable sleeve as needed.

[0020] Preferably, a first rotating shaft and a second rotating shaft are rotatably arranged on both sides of the opening groove, a first roller is fixedly arranged on the first rotating shaft, and a second roller is arranged on the second rotating shaft; a first gear is fixedly arranged on the first rotating shaft, and a second gear is arranged on the second rotating shaft; a first transmission gear and a second transmission gear are arranged between the first gear and the second gear to mesh and drive each other, the first gear meshes with the first transmission gear, and the second gear meshes with the second transmission gear.

[0021] When the first shaft rotates, it drives the first gear to rotate. The first gear, through the transmission of the first transmission gear and the second transmission gear, causes the second gear to rotate, which in turn causes the second shaft to rotate. The first shaft and the second shaft rotate in opposite directions.

[0022] Preferably, the side wall of the locking block is provided with a first through hole corresponding to the position of the first rotating shaft, and the first rotating shaft passes through the first through hole and is fixedly connected to the adjusting nut.

[0023] By rotating the adjusting nut, the first and second rotating shafts can be rotated, thereby facilitating the adjustment of the initial position between the first and second rollers to accommodate different connecting rope thicknesses.

[0024] Preferably, the side wall of the locking block is provided with a second through hole corresponding to the position of the second rotating shaft. The end of the second rotating shaft is provided with a connecting hole. The end of the second through hole near the connecting hole is provided with a mating hole. The inside of the second through hole is provided with a thread. The mating hole and the connecting hole are both polygonal holes of the same size. A sliding locking pin is slidably provided in the mating hole. The sliding locking pin is a polygonal prism that mates with the mating hole and the connecting hole. A spring is provided between the sliding locking pin and the connecting hole. The locking nut is threadedly engaged with the second through hole.

[0025] By rotating the locking nut, the rolling of the first and second rollers can be controlled, thereby controlling whether the annular sleeve formed by the connecting rope and the locking block is a movable sleeve or a fixed sleeve, making it convenient to adjust the state of the annular sleeve.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] (1) Set a lock so that loops can be easily formed at both ends of the connecting rope. One end of the loop is attached to the high platform and the other end is attached to the large tool, so that the large tool can be suspended on the high platform, saving the trouble of frequently passing large tools when working at height and improving the efficiency of high-altitude operations.

[0028] (2) Set a first roller and a second roller so that the ring sleeve formed by the connecting rope can form a fixed sleeve or a movable sleeve as needed, which is convenient for connection with large tools or high platforms. Attached Figure Description

[0042] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0043] Example 1: Refer to Figures 1 to 6 As shown, a fall arrest rope assembly for large tools used at heights includes a locking block 1 and a connecting rope 3, with both ends of the connecting rope 3 fixedly connected to the locking block 1.

[0044] The locking block 1 has an opening slot 11, and a sealing component 2 is provided at the opening of the opening slot 11 to close the opening slot 11. The two sides of the opening slot 11 are a first fixing plate 12 and a second fixing plate 13, respectively, which are connected by a connecting block. The first fixing plate 12 has a through slot 121, and the second fixing plate 13 has an abutment groove 131 on the side near the opening slot 11 that mates with the through slot 121. A limiting hole 132 is provided through the side wall of 131; the sealing assembly 2 includes a sealing plate 21 and a limiting pin 22. The lower end of the sealing plate 21 passes through the through groove 121 and abuts against the abutting groove 131. A limiting groove 211 is provided on the sealing plate 21 to cooperate with the limiting hole 132. The limiting groove 211 is a round-headed groove. The limiting pin 22 is slidably disposed in the limiting hole 132. A pushing member 23 is provided in the limiting hole 132 to push the limiting pin 22 to move towards the abutting groove 211.

[0045] A mounting groove 133 is provided circumferentially on the inner sidewall of the limiting hole 132. An abutment ring 221 is fixedly provided circumferentially on the limiting pin 22. The pushing member 23 is a pushing spring, which abuts against the end of the mounting groove 133 and the abutment ring 221. The pushing spring pushes the end of the limiting pin 22 to abut against the limiting groove 211. The end of the limiting pin 22 is provided with a round head that mates with the limiting groove 211.

[0046] To achieve better limiting effect, two limiting grooves 211 are provided in the width direction of the sealing plate 21, and two limiting holes 132 are provided on the side wall of the abutment groove 131. Two limiting pins 22 are respectively inserted into the two limiting holes 132. The two limiting pins 22 are connected by a connecting plate 24 at the end away from the sealing plate 21. The connection of the connecting plate 24 is convenient. By pulling the connecting plate 24, the connecting plate 24 can simultaneously drive the two limiting pins 22 to move.

[0047] The width of the two sides of the through groove 121, which is away from the opening groove 11, gradually increases outward to facilitate the insertion of the sealing plate 21 into the through groove 121. The end of the sealing plate 21 away from the abutment groove 131 is a pinch plate 212, which facilitates the removal of the sealing plate 21 from the through groove 121.

[0048] The working principle of this embodiment is as follows: Figure 5 As shown, during use, the connecting rope 3 is inserted into the opening slot 11, as follows. Figure 5 As shown, the ends of both ends of the connecting rope 3 are formed into a ring-shaped sleeve 7; one end of the ring-shaped sleeve 7 is fitted onto the high platform, and the other end is fitted onto the large tool, so that the large tool can be suspended on the high platform. Since the ring-shaped sleeve 7 is a movable sleeve with an adjustable size, the ring-shaped sleeve 7 can automatically shrink and become smaller by the weight of the large tool itself, and be tightly tied to the large tool, which can effectively prevent the large tool from falling.

[0049] The specific steps for inserting the connecting rope 3 into the opening groove 11 are as follows: First, pull the connecting plate 24, causing the connecting plate 24 to move the two connecting pins 22 away from the sealing plate 21, so that the ends of the connecting pins 22 disengage from the limiting groove 211. Then, pull the sealing plate 21 by the pinch plate 212, so that the sealing plate 21 disengages from the abutting groove 131, thus opening the opening groove 11. Then, insert the connecting rope 3 into the opening groove 11, and then push the sealing plate 21 so that the sealing plate 21 abuts against the abutting groove 131. When the sealing plate 21 abuts against the abutting groove 131, the limiting pin 22 is abutted against the limiting groove 211 by the force of the pushing spring, which limits the sealing plate 21 and prevents the sealing plate 21 from disengaging from the opening groove 11, thereby preventing the connecting rope 3 from disengaging from the opening groove 11.

[0050] Example 2: Refer to Figures 1 to 6 As shown, this embodiment is similar in structure to Embodiment 1, except that a first roller 4 and a second roller 5 are respectively inlaid on the two side walls of the opening groove 11. The first roller 4 and the second roller 5 are symmetrically arranged and rotate in opposite directions. Both the first roller 4 and the second roller 5 are rollers with varying radii, and the distance between the side of the cross section of the first roller 4 and the second roller 5 and the center of rotation changes. An adjusting nut 42 is fixedly connected to the end of the first roller 4. Rotating the adjusting nut 42 allows the angle of the first roller 4 and the second roller 5 to be adjusted, thereby adjusting the size of the gap between the first roller 4 and the second roller 5. A locking nut 52 is provided at the end of the second roller 5 to control its rotation. Rotating the locking nut 52 allows the first roller 4 and the second roller 5 to be locked.

[0051] A first rotating shaft 41 and a second rotating shaft 51 are rotatably mounted on both sides of the opening slot 11. A first roller 4 is fixedly mounted on the first rotating shaft 41, and a second roller 5 is mounted on the second rotating shaft 51. A first gear 411 is fixedly mounted on the first rotating shaft 41, and a second gear 511 is mounted on the second rotating shaft 51. A first transmission gear 61 and a second transmission gear 62 mesh with each other between the first gear 411 and the second gear 511. Both the first transmission gear 61 and the second transmission gear 62 are mounted on the rotating shaft, allowing both to rotate freely. The first gear 411 meshes with the first transmission gear 61, and the second gear 511 meshes with the second transmission gear 62. When the first rotating shaft 41 rotates, it drives the first gear 411 to rotate. The first gear 411, through the transmission of the first transmission gear 61 and the second transmission gear 62, causes the second gear 511 to rotate, thus causing the second rotating shaft 51 to rotate. The rotation directions of the first rotating shaft 41 and the second rotating shaft 51 are opposite.

[0052] The side wall of the locking block 1 is provided with a first through hole 14 corresponding to the position of the first rotating shaft 41. The first rotating shaft 41 passes through the first through hole 14 and is fixedly connected to the adjusting nut 42, so that rotating the adjusting nut 42 can drive the first rotating shaft 41 to rotate.

[0053] The side wall of the locking block 1 is provided with a second through hole 15 corresponding to the position of the second rotating shaft 51. The end of the second rotating shaft 51 is provided with a connecting hole 512. The end of the second through hole 15 near the connecting hole 512 is provided with a mating hole 151. The second through hole 151 is provided with a thread. The mating hole 151 and the connecting hole 512 are both polygonal holes of the same size. A sliding locking pin 53 is slidably provided in the mating hole 151. The sliding locking pin 53 is a polygonal prism that mates with the mating hole 151 and the connecting hole 512. The end of the sliding locking pin 53 near the connecting hole 512 is provided with a round head. The round head facilitates mating with the connecting hole 512. A spring 54 is provided between the sliding locking pin 53 and the connecting hole 512. A threaded rod 521 is provided on the locking nut 52. The threaded rod 521 is threadedly engaged with the second through hole 15.

[0054] The working principle of this embodiment is as follows: To adapt to different usage scenarios, when using the locking block 1 and connecting rope 3 to tie to a large tool, the weight of the large tool itself may cause the movable ring sleeve 7 to bind the large tool very tightly, making it very inconvenient to remove the ring sleeve 7 from the large tool later. Therefore, this embodiment is designed to control the size of the ring sleeve 7 and prevent the movable ring sleeve 7 from binding the large tool tightly. The specific principle is as follows:

[0055] like Figure 4As shown, in this embodiment, a first roller 4 and a second roller 5 are provided. During use, a connecting rope 3 is placed between the first roller 4 and the second roller 5. If it is desired to form a fixed sleeve of constant size for the annular sleeve 7, the locking nut 52 is rotated, causing the locking nut 52 to move away from the second rotating shaft 51, so that the sliding locking pin 53 is located outside the connecting hole 512, allowing the first roller 4 and the second roller 5 to rotate freely. When the annular sleeve 7 contracts due to the weight of the large tool, the connecting rope 3 moves between the first roller 4 or the second roller 5. The connecting rope 3 drives the first roller 4 and the second roller 5 to rotate through friction. Since the first roller 4 and the second roller 5 are symmetrically arranged and rotate in opposite directions, the gap between the first roller 4 and the second roller 5 becomes smaller and smaller until the first roller 4 and the second roller 5 are clamped on the connecting rope 3, so that the annular sleeve 7 forms a fixed sleeve of constant size.

[0056] When it is necessary to make the annular sleeve 7 a movable sleeve with expandable size, the locking nut 52 is rotated, causing the locking nut 52 to move towards the second rotating shaft 51. This causes the locking nut 52 to push the sliding locking pin 53 to move, so that one part of the sliding locking pin 53 is located in the connecting hole 512 and the other part is located in the mating hole 151. This locks the second rotating shaft 51 by the action of the sliding locking pin 53, thereby stopping the first rotating shaft 41 and the second rotating shaft 51 from rotating. This prevents the first roller 4 and the second roller 5 from rotating due to the friction of the connecting rope 3, thus making the annular sleeve 7 a movable sleeve with expandable size.

[0057] Furthermore, by rotating the adjusting nut 42, the first rotating shaft 41 and the second rotating shaft 51 can be rotated, thereby facilitating the adjustment of the initial position between the first roller 4 and the second roller 5 to accommodate different connecting rope thicknesses. In this embodiment, using a ribbon rope for the connecting rope 3 provides even better results.

[0058] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
