Description

Technical Field

[0001] The utility model relates to the technical field of anti-fall protection devices on power and communication pole towers, in particular to a reinforced rigid anti-fall guide rail. Background Art

[0002] At present, the height of power and communication towers is basically above 20 meters. In order to ensure the safety of workers, they must use anti-fall devices when installing, inspecting and maintaining the lines. The anti-fall devices include anti-fall rails and fall arresters equipped with anti-fall rails. The fall arresters are connected to the safety belts worn by the workers themselves.

[0003] For rigid anti-fall rails, the rails are generally split structures, assembled from multiple sections. When a fall occurs, the fall arrester forces the cam to squeeze the rail under the action of gravity, and the rail bears sudden large lateral and longitudinal pressure. Therefore, the reliability of the connection of the rigid anti-fall rail is the prerequisite for ensuring the effective use of the anti-fall device.

[0004] The joints of conventional rigid anti-fall rails are fixed by bolts, nuts and connecting plates, which have poor reliability. When the rails are used for a long time, the joints are deformed, and when the bolts are loose, the joints of the anti-fall rails are misaligned, which destroys the function of the rails. In this case, the fall arrester fails, posing a fatal threat to the lives of construction workers. Utility Model Content

[0008] It also includes two pads, which are respectively located on both sides of the mounting portion;

[0009] A set of plates is arranged outside the two pads, the set of plates includes a connecting portion and two side plates parallel to each other, the adjacent sides of the two side plates are fixedly connected by the connecting portion, and a side avoidance opening cooperating with the mounting portion is formed between the other adjacent sides of the two side plates, and the side avoidance opening is opposite to the connecting portion;

[0010] The two side plates are respectively located outside the two pads, and are used to limit the relative displacement of the two pads, thereby limiting the relative displacement of adjacent mounting parts in a direction perpendicular to the plane of the mounting parts. Each pad is also matched with the end of the adjacent mounting part, and is used to limit the relative displacement of the adjacent mounting parts in the plane direction of the mounting part.

[0011] The sleeve plate is provided with a plurality of fastening components along the length direction of the guide rail, and the plurality of fastening components fix the sleeve plate, the mounting portion and the two pads together, so as to limit the relative displacement of adjacent mounting portions along the guide rail direction.

[0012] As a further improvement of the above technical solution:

[0013] The planes on both sides of the end of the mounting portion are provided with grooves, and the grooves penetrate the end of the mounting portion;

[0014] After the adjacent mounting parts are butted, two grooves located on different mounting parts are butted to form an assembly groove, and the assembly groove cooperates with the pad to limit the relative displacement of the adjacent mounting parts in the plane direction of the mounting parts.

[0015] The depth of the groove is 20%-25% of the thickness of the mounting portion.

[0016] The thickness of the backing plate is greater than the depth of the groove.

[0017] The sleeve plate is provided with a first channel and a second channel at two ends along the length direction of the guide rail, respectively, and the first channel and the second channel are both communicated with the side avoidance opening.

[0018] The side plate is provided with a limiting groove, the limiting groove cooperates with the pad, and the limiting groove is connected with the first channel.

[0019] The pad includes a rectangular plate-shaped body, and the right angles of the plate-shaped body are all provided with arc chamfers.

[0020] A guide groove matched with the side edge of the mounting portion is arranged on the inner side of the side plate, and the width of the guide groove is the same as the width of the second channel, and both are matched with the thickness of the mounting portion.

[0021] The structure of the fastening assembly includes a bolt and a nut matched with the tail of the bolt;

[0022] A first through hole is provided at both ends of the mounting portion, a second through hole corresponding to the first through hole is provided on the side plate, a third through hole corresponding to the first through hole is provided on the pad plate, and the bolt passes through the first through hole, the second through hole and the third through hole at the same time.

[0023] The number of the first through holes at one end of the mounting portion is two, and the angle between the straight line where the centers of the two first through holes are located and the length direction of the guide rail is greater than zero.

[0024] The beneficial effects of the utility model are as follows:

[0025] The utility model discloses the structure is compact and reasonable, and is easy to operate. By adopting the connection structure of the combination of the sleeve plate, the pad plate and the fastening assembly, the connection is limited from two vertical directions of the guide rail cross section, thereby improving the strength of the connection. When the bolts of the fastening assembly are loosened, the limit in the length direction of the guide rail and the limit in the cross-section direction of the guide rail will not fail, thereby preventing the guide rail function from failing when the bolts are loosened, and improving the safety reliability of the rigid guide rail and the safety factor of the anti-fall device.

[0042] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0043] like Figure 1-Figure 4 As shown, the reinforced rigid anti-falling guide rail of this embodiment includes a plurality of guide rail bodies connected end to end, the guide rail body includes a guide portion 1 and a mounting portion 2, the guide portion 1 and the mounting portion 2 are plate-like structures and are perpendicular to each other, and the guide portion 1 is equipped with the anti-falling device;

[0044] It also includes two pads 5, which are respectively located on both sides of the mounting portion 2;

[0045] A set plate 3 is arranged outside the two pads 5, and the set plate 3 includes a connecting portion 33 and two side plates 31 parallel to each other. The adjacent sides of the two side plates 31 are fixedly connected by the connecting portion 33, and a side avoidance opening 35 cooperating with the mounting portion 2 is formed between the other adjacent sides of the two side plates 31, and the side avoidance opening 35 is opposite to the connecting portion 33;

[0046] The two side plates 31 are respectively located outside the two pads 5, and are used to limit the relative displacement of the two pads 5, thereby limiting the relative displacement of the adjacent mounting parts 2 in the direction perpendicular to the plane of the mounting parts 2. Each pad 5 is also matched with the end of the adjacent mounting part 2, and is used to limit the relative displacement of the adjacent mounting parts 2 in the plane direction of the mounting parts 2.

[0047] The sleeve plate 3 is provided with a plurality of fastening components 4 along the length direction of the guide rail, and the plurality of fastening components 4 fix the sleeve plate 3, the mounting portion 2 and the two pads 5 together to limit the relative displacement of adjacent mounting portions 2 along the guide rail direction.

[0048] When the sleeve plate 3 is put on the outside of the pad 5 and the mounting part 2, the adjacent guide rail bodies are limited in two vertical directions of the guide rail cross section, which improves the accuracy of the guide rail assembly process, avoids the fall arrester from getting stuck at the connection of the rigid guide rail, and improves the smoothness of the fall arrester passing through the connection. After the fastening assembly 4 is installed, the mounting part 2, the pad 5 and the side plate 31 are stacked and fitted together, and the adjacent guide rail bodies are surface constrained from both sides of the mounting part 2, which improves the strength of the guide rail connection.

[0049] The plurality of fastening components 4 may be arranged in a straight line along the length direction of the guide rail and be parallel to the length direction of the guide rail.

[0050] During operation, the joints of the guide rails are usually subjected to greater stress and torque. The pad 5 and the side plate 31 can provide a certain resistance to the surface constraints of the adjacent guide rail bodies, thereby increasing the load resistance of the rigid guide rail and improving the force bearing capacity of the guide rail in both the horizontal and vertical directions and its reliability during operation.

[0051] When the guide rail is used for a long time or is subjected to excessive longitudinal and lateral pressure, even if the bolts 41 of the fastening assembly 4 become loose, the limiting effect of the fastening assembly 4 on the adjacent mounting parts 2 along the guide rail direction still exists. Combined with the limiting effect of the above-mentioned sleeve plate 3 and pad 5 on the adjacent mounting parts 2 in the guide rail cross-sectional direction, the connection of the anti-fall guide rail will not be misaligned, ensuring that the guide rail function will not fail, and further protecting the personal safety of construction workers without affecting the original function of the guide rail.

[0052] By adopting a connection structure composed of a sleeve plate 3, a pad 5 and a fastening assembly 4, the connection is limited in two vertical directions of the guide rail cross section, thereby improving the strength of the connection. When the bolt 41 of the fastening assembly 4 is loosened, the limit in the guide rail length direction and the limit in the guide rail cross section direction are not invalid, thereby preventing the guide rail function from failing when the bolt 41 is loosened, thereby improving the safety reliability of the rigid guide rail and the safety factor of the anti-fall device.

[0053] Further, if Figure 2-Figure 5 As shown, grooves 21 are provided on both side planes of the end of the mounting portion 2, and the grooves 21 penetrate the end of the mounting portion 2;

[0054] After the adjacent mounting parts 2 are butted together, two grooves 21 located on different mounting parts 2 are butted together to form an assembly groove, which cooperates with the pad 5 to limit the relative displacement of the adjacent mounting parts 2 in the plane direction of the mounting parts 2 .

[0055] Specifically, the matching structure between the assembly groove and the pad 5 is similar to the matching mode of the keyway. The two side plates 31 of the sleeve plate 3 limit the distance between the two pads 5, and then limit the relative displacement of the two pads 5, so as to achieve the limitation of the connection in the direction of the guide rail cross section.

[0056] like Figure 2-Figure 4 As shown, the depth of the groove 21 is 20%-25% of the thickness of the mounting portion 2 .

[0057] The thickness of the backing plate 5 is greater than the depth of the groove 21 .

[0058] For the guide rail body, the guide portion 1 and the mounting portion 2 are perpendicular to each other and are in a T-shape as a whole. The guide rail body can be integrally cast. The thickness of the mounting portion 2 is in the range of 5-10 mm.

[0059] Further, if Figure 2-Figure 9 As shown, the sleeve plate 3 is provided with a first channel 34 and a second channel 36 at both ends along the length direction of the guide rail, and the first channel 34 and the second channel 36 are both connected to the side avoidance opening 35 .

[0060] A limiting groove 38 is provided on the side plate 31 . The limiting groove 38 cooperates with the backing plate 5 , and the limiting groove 38 is connected to the first passage 34 .

[0061] The pad 5 comprises a rectangular plate-shaped body 53 , and arc chamfers 51 are arranged at right angles of the plate-shaped body 53 .

[0062] A guide groove 37 matching the side edge of the mounting portion 2 is disposed on the inner side of the side plate 31 . The width of the guide groove 37 is the same as the width of the second channel 36 , and both match the thickness of the mounting portion 2 .

[0063] The assembly process of the reinforced rigid anti-fall guide rail of this embodiment is as follows:

[0064] After the two guide rail bodies are butted together, the two pads 5 are installed in the assembly grooves;

[0065] Then, the mounting part 2 is passed through the side avoidance opening 35 so that the sleeve plate 3 is sleeved on the mounting part 2 above the pad 5, and the sleeve plate 3 is slid downward along the guide groove 37 along the side of the mounting part 2;

[0066] When the lower end of the sleeve plate 3 and the upper end of the pad plate 5 are at the same height, the sleeve plate 3 continues to slide downward. Under the guidance of the arc chamfer 51, the first channel 34 is sleeved on the outside of the pad plate 5. At the same time, the limiting groove 38 cooperates with the pad plate 5, and the sleeve plate 3 is limited in the direction of the guide rail cross section. The sleeve plate 3 also limits the relative displacement of the two pad plates 5, realizing the limitation of the connection from two vertical directions of the guide rail cross section.

[0067] Since the second channel 36 is smaller than the distance between the outer sides of the two pads 5 and matches the thickness of the mounting portion 2, when the upper end of the limiting groove 38 contacts the upper end of the pad 5, the sleeve plate 3 cannot continue to slide downward, and the sleeve plate 3, the mounting portion 2 and the two pads 5 are fixed together by the fastening assembly 4, thereby completing the connection of the two guide rail bodies.

[0068] Further, if Figure 2-Figure 9 As shown, the structure of the fastening assembly 4 includes a bolt 41 and a nut 42 matched with the tail of the bolt 41;

[0069] A first through hole 22 is provided at both ends of the mounting portion 2, a second through hole 32 corresponding to the first through hole 22 is provided on the side plate 31, a third through hole 52 corresponding to the first through hole 22 is provided on the pad 5, and the bolt 41 passes through the first through hole 22, the second through hole 32 and the third through hole 52 at the same time.

[0070] Specifically, the first through hole 22 is located at the bottom of the groove 21, and the nut 42 adopts an anti-loosening design.

[0071] There are two first through holes 22 at one end of the mounting portion 2, and the angle between the straight line where the centers of the two first through holes 22 are located and the length direction of the guide rail is greater than zero.

[0072] Specifically, the angle is 15 degrees to 25 degrees.

[0073] The connection structure of the reinforced rigid anti-fall guide rail in this embodiment adds a keyway connection design, and at the same time, the sleeve plate 3 is used to limit the pad 5 at the guide rail connection, thereby improving the installation accuracy and safety reliability of the rigid guide rail. The through holes are staggered so that after the multiple fastening components 4 are installed, the points of force applied to the two side plates 31 of the sleeve plate 3 are dispersed in a planar distribution, so that the stacking fit between the mounting portion 2, the pad 5 and the side plates 31 is better.

[0074] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
