Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide rail device technology, and more specifically, to a T-shaped guide rail assembly. Background Technology
[0002] Currently, during the installation of rigid fall arrestor rails, adjacent rails need to be fixed together using connectors. The interface between adjacent rails is typically a straight line. Since the fall arrestor's pulleys must pass through this interface simultaneously, this can cause the fall arrestor to undulate and jam on-site. Furthermore, due to manufacturing and installation errors, the straight line interface often leads to stress interference or tension at the joint between adjacent rail sections. As a result, the rail is already under stress before bearing the impact load of a fall, thus reducing its impact resistance. Utility Model Content
[0003] The present invention aims to overcome at least one of the defects of the prior art and provide a T-shaped guide rail assembly to solve the problem of uneven sliding of the fall arrestor.
[0004] The technical solution adopted by this utility model is to provide a T-shaped guide rail assembly, including a plurality of T-shaped rail components arranged sequentially along the length direction, and adjacent T-shaped rail components are connected and fixed by a connecting device;
[0005] The T-shaped track component has a first end face and a second end face at both ends along its length. The T-shaped track component includes a horizontal plate and a vertical plate that are perpendicularly connected in a "T" shape. The first end of the horizontal plate and the first end of the vertical plate together form the first end face, and the second end of the horizontal plate and the second end of the vertical plate together form the second end face. The first end face and the second end face are adapted to mate with each other. The first end of the horizontal plate has a first mating part with a mating surface of a first curved surface, and the second end of the horizontal plate has a second mating part with a mating surface of a second curved surface. The shapes of the first curved surface and the second curved surface are complementary.
[0006] The connecting devices are fixedly connected to the longitudinal plates of adjacent T-shaped track components, and the connecting devices and the transverse plates of the T-shaped track components are spaced apart.
[0007] In this design, by setting the mating surfaces of the first and second mating parts as complementary curved surfaces, the interface formed by the mating of the first and second end faces between adjacent T-shaped track components is curved. Since the pulleys of fall arresters are usually arranged in multiple rows, the curved interface of this design can prevent pulleys in the same row from rolling through the interface simultaneously, effectively improving the smoothness of the fall arrester's sliding. The spacing between the connecting device and the cross plate facilitates the smooth passage of the pulleys. Furthermore, the curved interface reduces the risk of misalignment of connected T-shaped track components, improves the strength of the guide rail connection, and the smooth contact surface of the curved interface helps to evenly transmit stress, enhancing the structural strength of the T-shaped track components.
[0008] In some embodiments, the interface formed by the first mating part and the second mating part is wavy.
[0009] The interface of this solution presents a curve with alternating peaks and troughs, exhibiting a large curvature variation. This better prevents pulleys on the same horizontal row of the fall arrestor from passing through the interface simultaneously, thus improving the smoothness of the fall arrestor's up-and-down sliding.
[0010] In some implementations, the first and second end faces of adjacent T-shaped track members that are close to each other are spaced apart.
[0011] This design avoids interference fits between adjacent T-shaped rail components, thereby reducing the temperature stress generated by the T-shaped rail components during thermal expansion and contraction.
[0012] In some embodiments, the connecting device includes a connecting plate and several fasteners. The connecting plate has several first connecting holes, and the longitudinal plate has several through holes. The positions of the first connecting holes correspond one-to-one with the through holes. The fasteners pass through the first connecting holes and the through holes and are fixedly engaged with the corresponding longitudinal plates.
[0013] In some embodiments, the two ends of the connecting plate are respectively provided with a first fall arrestor guide and a second fall arrestor guide.
[0014] In this design, the connecting plate protrudes from the surface of the horizontal plate of the T-shaped track component, and the gap between the connecting plate and the horizontal plate forms a sliding channel for the fall arrester. The two ends of the connecting plate and the horizontal plate respectively form a sliding entrance and a sliding exit for the fall arrester to enter and exit the sliding channel. By setting the first fall arrester guide and the second fall arrester guide, the smoothness of the fall arrester's up and down sliding process is improved, and it is avoided from being obstructed by the connecting plate.
[0015] In some embodiments, the first fall arrestor guide includes a first wedge-shaped member connected to a first end of the connecting plate.
[0016] In some embodiments, the second fall arrestor guide includes a second wedge-shaped member connected to the second end of the connecting plate.
[0017] The design features a funnel shape between the horizontal plate and the wedge-shaped component, which facilitates the sliding of the fall arrestor into or out of the gap between the connecting device and the horizontal plate, thus improving the smoothness of the fall arrestor's sliding.
[0018] In some embodiments, the connecting plate is further provided with a second connecting hole, the first end of the longitudinal plate is provided with a first notch, the second end of the longitudinal plate is provided with a second notch, the first notch and the second notch are adapted to cooperate to form a positioning slot, and the position of the second connecting hole corresponds to the positioning slot.
[0019] The connecting device also includes a positioning element that passes through the second connecting hole and the positioning slot.
[0020] In some embodiments, both the second connecting hole and the positioning slot are elongated holes.
[0021] In some implementations, the first notch and the second notch have the same shape and are mirror images of each other.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the first mating part and the second mating part as curved surfaces that can complement each other, the interface formed by the mating of the first end face and the second end face between adjacent T-shaped track components is curved, which can prevent the pulleys of the fall arrestor from rolling through the interface at the same time, effectively improving the smoothness of the fall arrestor's sliding. Moreover, the curved interface can prevent the connected T-shaped track components from misaligning, thus improving the strength of the guide rail connection. By setting a wedge-shaped component on the connecting device, a flared shape is formed between the horizontal plate and the wedge-shaped component, which facilitates the fall arrestor entering the gap between the connecting device and the horizontal plate. By using a gap setting at the interface, interference fit can be avoided. Combined with the design of the elongated oval positioning slot, the alignment stability of the T-shaped track components can be improved, and stress transmission can be facilitated, thereby increasing the strength.

[0032] Example 1
[0033] like Figure 1-3 As shown, this embodiment provides a T-shaped guide rail assembly, including a plurality of T-shaped rail components 100 arranged sequentially along the length direction, and adjacent T-shaped rail components 100 are connected and fixed by a connecting device;
[0034] refer to Figure 2-4The T-shaped track component 100 has a first end face 110 and a second end face 120 at both ends along its length. The T-shaped track component 100 includes a horizontal plate 130 and a vertical plate 140 that are perpendicularly connected in a "T" shape. The first end of the horizontal plate 130 and the first end of the vertical plate 140 together form the first end face 110, and the second end of the horizontal plate 130 and the second end of the vertical plate 140 together form the second end face 120. The first end face 110 and the second end face 120 are adapted to be fitted together. The first end of the horizontal plate 130 has a first mating part 131 with a mating surface of a first curved surface, and the second end of the horizontal plate 130 has a second mating part 132 with a mating surface of a second curved surface. The shapes of the first curved surface and the second curved surface are complementary.
[0035] The connecting devices are fixedly connected to the longitudinal plates 140 of adjacent T-shaped track components 100, and the connecting devices and the corresponding transverse plates 130 of the T-shaped track components 100 are spaced apart. The gap between the connecting devices and the transverse plates 130 is suitable for the fall arrester to slide up and down. In actual use, the transverse plates 130 serve as guide plates when the fall arrester slides up and down.
[0036] Continue to refer to Figure 3 For ease of understanding, this embodiment specifically uses the example of two T-shaped track components 100 being fixed by a connecting device. The connecting device includes a connecting plate 200 and several fixing components 300. The connecting plate 200 has several first connecting holes 210, and each longitudinal plate 140 of the T-shaped track component 100 has several through holes 141. The positions of the first connecting holes 210 correspond one-to-one with the through holes 141. The fixing components 300 pass through the first connecting holes 210 and the through holes 141 to fix and engage with the corresponding longitudinal plate 140. In specific implementation, the fixing components 300 can be in the form of bolt and nut assemblies.
[0037] refer to Figure 1-4When adjacent T-shaped track components 100 are spliced together by a connecting device, the longitudinal plates 140 of the two T-shaped track components 100 are fixedly connected by a connecting plate 200 and a fixing member 300. The first mating part 131 of one T-shaped track component 100 is positioned opposite to the second mating part 132 of the adjacent T-shaped track component 100. Since the first and second curved surfaces are complementary, the first mating parts 131 and 132 of the adjacent transverse plates 130 of the T-shaped track components 100 form a curved interface. It is easy to understand that in practical implementation, whether the first mating part 131 and the second mating part 132 use an abutment fit or a clearance fit, this curved interface can be achieved. In practical applications, since the pulleys of the fall arrestor are usually arranged in multiple rows, when the pulleys of the fall arrestor pass through the interface, the curved interface can avoid being on the same horizontal line as all the pulleys in the same row, thus improving the smoothness of the fall arrestor's up-and-down sliding. Furthermore, the curved interface can reduce the risk of misalignment of the connected T-shaped track components 100 and improve the strength of the guide rail connection. At the same time, the curved interface has a smooth contact surface, which helps to uniformly transmit stress and improve the structural strength of the T-shaped track components 100.
[0038] Further, continue to refer to Figure 1 To ensure a secure connection between adjacent T-shaped track components 100, two connecting plates 200 are provided. The two connecting plates 200 are symmetrically arranged on both sides of the longitudinal plate 140. Furthermore, the two connecting plates 200 clamp and fix the longitudinal plate 140 of the adjacent T-shaped track components 100 through the fixing member 300.
[0039] like Figure 2 As shown, the interface formed by the first mating part 131 and the second mating part 132 is wavy. The wavy interface presents a curved shape with alternating peaks and troughs, and has a large curvature change, which is more conducive to the staggered contact between the pulleys on the same horizontal row on the fall arrestor and the interface.
[0040] In specific implementation, refer to Figure 2-3 To eliminate the temperature stress caused by the thermal expansion and contraction of the T-shaped track components 100, a gap is provided between the first end face 110 and the second end face 120 of adjacent T-shaped track components 100. That is, a gap is left between adjacent horizontal plates 130 and adjacent vertical plates 140, and a gap is left between the mating first mating part 131 and the mating second mating part 132. This avoids interference fits between adjacent T-shaped track components 100 and helps reduce the temperature stress generated during thermal expansion and contraction. In specific implementations, the size of this gap can be set to 1-5mm. This size is sufficient to eliminate temperature stress and avoids excessively large gaps affecting the connection strength between the T-shaped track components.
[0041] refer to Figure 1 , 3 The connecting plate 200 protrudes from the surface of the horizontal plate 130 of the T-shaped track component 100. The gap between the connecting plate 200 and the horizontal plate 130 forms a sliding channel 600 for the fall arrester. At both ends of the connecting plate 200 and the horizontal plate 130, sliding entrances 610 and sliding exits 620 are respectively constructed for the fall arrester to enter and exit the sliding channel 600. Clearly, the connecting plate 200 narrows the planar area on the surface of the vertical plate 140 where the fall arrester can pass smoothly. To improve the efficiency of the fall arrester entering or exiting the sliding channel 600, a first fall arrester guide and a second fall arrester guide are respectively provided at both ends of the connecting plate 200. This improves the smoothness of the fall arrester's up-and-down sliding process and avoids obstruction by the connecting plate 200.
[0042] In specific implementation, refer to Figure 3 , 5 The first fall arrestor guide includes a first wedge 400 connected to the first end of the connecting plate 200. The distance between the first wedge 400 and the corresponding horizontal plate 130 gradually narrows from the outer end of the first wedge 400 toward the connection between the first wedge 400 and the connecting plate 200, so that the sliding entrance 610 presents a funnel shape. This structure is simple and enables the fall arrestor to be quickly and smoothly guided into the sliding channel 600.
[0043] Similarly, in a preferred embodiment, the second fall arrestor guide includes a second wedge 500 connected to the second end of the connecting plate 200. The distance between the second wedge 500 and the corresponding cross plate 130 gradually narrows from the outer end of the second wedge 500 toward the connection between the second wedge 500 and the connecting plate 200. By providing the wedge, the slide outlet 620 presents a trumpet shape. This structure is simple and enables the fall arrestor to exit the sliding channel 600 quickly and smoothly. In specific implementation, to simplify processing, the first wedge 400 and the second wedge 500 are integrally formed with the connecting plate 200. Specifically, wedges can be machined at both ends of the substrate used to make the connecting plate 200, so that the first wedge 400 and the second wedge 500 are integrally formed at both ends of the connecting plate 200, thus providing a high connection strength between the connecting member 200 and the first wedge 400 and the second wedge 500.
[0044] refer to Figure 3-5The connecting plate 200 is also provided with a second connecting hole 220. The first end of the longitudinal plate 140 is provided with a first notch 142, and the second end of the longitudinal plate 140 is provided with a second notch 143. The first notch 142 and the second notch 143 are adapted to cooperate to form a positioning slot 144. The position of the second connecting hole 220 corresponds to the positioning slot 144. The connecting device also includes a positioning element, which passes through the second connecting hole 220 and the positioning slot 144 to position the two adjacent longitudinal plates 140. When adjacent T-shaped track pieces 100 are connected by the connecting device, the first end face 110 and the second end face 120 are in clearance fit. The first notch 142 and the second notch 143 cooperate to form the positioning slot 144. The positioning element passes through the second connecting hole 220 and the positioning slot 144 of the connecting plate 200, which plays a positioning and stabilizing role in the connection of adjacent T-shaped track pieces 100, significantly reducing the horizontal offset and shaking of the T-shaped track pieces 100, and improving the connection tightness between adjacent T-shaped track pieces 100. In practice, the positioning element can be a pin whose outer shape is adapted to the positioning slot 144.
[0045] For specific implementation, refer to Figure 3 , 5 The second connecting hole 220 and the positioning slot hole 144 are both elongated holes. The elongated holes have smooth circumferences, which can avoid stress concentration. Furthermore, the elongated holes cooperate with the positioning parts with appropriate shapes, which has good positioning stability.
[0046] refer to Figure 4 The first notch 142 and the second notch 143 have the same shape and are mirror images of each other. Thus, by simply connecting T-shaped rail components 100 of the same specification through a connecting device, a T-shaped guide rail assembly with a stable structure and smooth up-and-down sliding of the fall arrester can be obtained. Furthermore, by connecting and assembling several T-shaped guide rail assemblies through a connecting device, a fall arrester guide rail suitable for installation on power facilities with a stable structure and smooth up-and-down sliding can be obtained.
[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
