[0031] Refer to Figures 1 to 4 As shown, an embodiment of the present utility model provides a pulley clamp 10 for a transmission line, which includes a connecting frame 100, a clamping part 200 and at least one set of fasteners 300; the connecting frame 100 is provided with a fixing hole 1211 for connecting with a pulley suspension cable. For example, the pulley can be connected to the pulley clamp 10 by passing a suspension cable such as a steel cable through the fixing hole 1211; the clamping part 200 includes a clamping portion 210 and a reinforcing part 220. At least part of the clamping portion 210 is bent, and the reinforcing part 220 is respectively connected to at least two sides of the clamping portion 210.

When the number of the fasteners 300 is multiple groups, the connection strength between the clamping part 200 and the connecting frame 100 can be improved.

[0032] When using the pulley clamp 10 of this embodiment, first place the connecting frame 100 on one side of the angle steel of the cross-arm steel, and then place the clamping part 200 on the other side of the angle steel. At this time, the connecting frame 100 and the clamping part 200 can respectively be in close contact with the opposite sides of the angle steel. Then fix the fasteners 300 to the clamping part 200 and the connecting frame 100 respectively, and the pulley clamp 10 can be fixedly connected to the cross-arm steel. At this time, it can be connected to the pulley through the fixing hole 1211.

[0033] The pulley fixture 10 of this embodiment can be quickly connected to and disassembled from the cross-arm steel by setting the clamping member 200 and the connecting frame 100 in cooperation. The overall structure is simple, and the contact area with the angle steel is large, which can avoid damaging the galvanized layer on the surface of the angle steel, and has good use effect.

[0034] Specifically, the connecting frame 100 is provided with adjustment holes, the clamping portion 210 is provided with connection holes, and the fasteners 300 are respectively passed through the connection holes and the adjustment holes, and the orthographic projection of the fasteners 300 on the connecting frame 100 is located within the adjustment holes.

[0035] With this setting, when the clamping member 200 is connected to the connecting frame 100, the position of the fasteners 300 in the adjustment holes can be adjusted according to the specific size of the angle steel in the cross-arm steel, so that the pulley fixture 10 can be applicable to different specifications of angle steel connection operations; of course, when the connection holes are of a fixed structure, different specifications of clamping members 200 can be replaced to make the connection holes correspond to different positions of the adjustment holes, and the connection holes can also be set as a combined structure of multiple holes to adapt to the adjustment holes, which is not uniquely limited here.

[0036] Specifically, referring to Figure 2 As shown, the connecting frame 100 includes a frame body 110 and at least one connecting portion 120. A fixing hole 1211 is provided in the connecting portion 120, and the connecting portion 120 is connected to the side of the frame body 110 away from the clamping member 200; when the number of connecting portions 120 is multiple, the multiple connecting portions 120 are respectively provided on multiple side surfaces of the frame body 110.

[0037] In this embodiment, the connecting portion 120 protrudes from the side of the frame body 110 away from the clamping member 200. In some embodiments, the connecting portion 120 is usually provided at the bottom of the frame body 110, which is convenient for the sling of the pulley to be connected to the connecting portion 120; referring to Figure 3 As shown, in another embodiment, the number of connecting portions 120 is two, and the two connecting portions 120 are respectively provided at the bottom and side of the frame body 110. With this setting, the pulley fixture 10 can install the pulley sling according to different operation requirements, and has good use effect.

[0038] Furthermore, the connecting portion 120 includes a connecting ring 121 and at least one reinforcing ear 122. The fixing hole 1211 is provided on the connecting ring 121, the connecting ring 121 is connected to the frame body 110, and the reinforcing ears 122 are respectively connected to the side wall of the connecting ring 121 and the frame body 110.

[0039] In this embodiment, by providing a reinforcing ear 122 on one side of the connecting ring 121 to connect with the frame body 110, at this time, the connecting ring 121, the reinforcing ear 122 and the frame body 110 are connected to each other, thereby improving the overall strength of the connecting frame 100. Of course, the connecting frame 100 can be integrally formed by pouring or other means to make the connecting frame 100 have higher strength. When the number of the reinforcing ears 122 is two, the two reinforcing ears 122 can be symmetrically arranged on the opposite sides of the connecting ring 121 respectively.

[0040] In one embodiment, the adjustment hole is a strip hole.

[0041] With this setting, the installation position of the fastener 300 can be adjusted along the length direction of the adjustment hole.

[0042] Specifically, referring to Figure 2 and Figure 3 As shown, the frame body 110 includes a first connecting plate 111 and a second connecting plate 112. The first connecting plate 111 is connected to the second connecting plate 112, and the first connecting plate 111 and the second connecting plate 112 are perpendicularly arranged; the adjustment holes include a first adjustment hole 1111 and a second adjustment hole 1121. The first adjustment hole 1111 is provided on the first connecting plate 111, and the second adjustment hole 1121 is provided on the second connecting plate 112; the number of the connecting holes is at least two groups, and two of the groups of connecting holes correspond to the first adjustment hole 1111 and the second adjustment hole 1121 respectively. One group of fasteners 300 is connected to the first adjustment hole 1111 and one group of connecting holes, and the other group of fasteners 300 is connected to the second adjustment hole 1121 and the other group of connecting holes.

[0043] In this embodiment, the first connecting plate 111 and the second connecting plate 112 are connected to form an L-shaped structure. When the connecting frame 100 is connected to the angle steel, it can be ensured that the first connecting plate 111 and the second connecting plate 112 are respectively attached to the adjacent side surfaces of the angle steel, thereby increasing the contact area and the stress area between the connecting frame 100 and the angle steel. Then, the clamping member 200 is brought into contact with the side of the angle steel away from the connecting frame 100, and by pressing the clamping member 200 and the connecting frame 100 with the fastener 300, the pulley fixture 10 can be fixed to the angle steel. During the installation process of the fastener 300, multiple groups of fasteners 300 can be respectively connected to the first adjustment hole 1111 and the second adjustment hole 1121 and the installation position can be adjusted according to the size of the angle steel, and the assembly is convenient.

[0044] It should be noted that the connection between the first connecting plate 111 and the second connecting plate 112 pointed out above is not limited to the two being in a split structure. When the first connecting plate 111 and the second connecting plate 112 are processed and formed by an integral molding method, it can also be considered as a connected state.

[0045] Specifically, referring toFigure 4 As shown, the clamping part 210 includes a first clamping plate 211 and a second clamping plate 212. The first clamping plate 211 is connected to the second clamping plate 212, and the first clamping plate 211 is perpendicularly arranged with respect to the second clamping plate 212. The connecting holes include a first connecting hole 2111 and a second connecting hole 2121. The first connecting hole 2111 is provided on the first clamping plate 211, and the second connecting hole 2121 is provided on the second clamping plate 212. When the clamping member 200 is connected to the connecting frame 100, the first clamping plate 211 is spaced and parallel to the first connecting plate 111, and one set of fasteners 300 respectively pass through the first connecting hole 2111 and the first adjusting hole 1111. The second clamping plate 212 is spaced and parallel to the second connecting plate 112, and the other set of fasteners 300 respectively pass through the second connecting hole 2121 and the second adjusting hole 1121.

[0046] In this embodiment, the first clamping plate 211 and the second clamping plate 212 are connected to form an L-shaped structure. With this arrangement, when the clamping member 200 is connected to the angle steel, the clamping member 200 can be attached to the side of the angle steel away from the connecting frame 100. Thus, the clamping member 200, the angle steel, and the connecting frame 100 are sequentially fitted, and are tightly connected by the fasteners 300. Thereby, the pulley clamp 10 can be fixed on the angle steel, and the angle steel is connected to the connecting frame 100 and the clamping member 200 in a surface contact manner respectively to reduce the contact pressure between the adjacent two, so as to improve the use safety of the pulley clamp 10.

[0047] Specifically, the reinforcing part 220 includes a side plate 221 and a cross plate 222. The side plate 221 is respectively connected to the first clamping plate 211 and the second clamping plate 212, and the cross plate 222 is respectively connected to the side plate 221 and the clamping part 210.

[0048] With this arrangement, the side plate 221 can connect the first clamping plate 211 and the second clamping plate 212 and improve the overall strength of the clamping part 210. Then, by arranging the cross plate 222 between the side plate 221 and the clamping part 210, the strength of the clamping member 200 can be further improved.

[0049] Furthermore, the number of the side plates 221 is two, and the two side plates 221 are symmetrically arranged on the opposite sides of the cross plate 222.

[0050] In this embodiment, the two side plates 221 and the cross plate 222 are connected to form an H-shaped structure, and the end of the cross plate 222 can be connected to the connection position of the first clamping plate 211 and the second clamping plate 212 to further improve the strength of the clamping member 200. At the same time, since the two side plates 221 are spaced apart, the first connecting hole 2111 and the second connecting hole 2121 can also be exposed, facilitating the operator to assemble the fasteners 300.

[0051] Specifically, the fastener 300 includes a bolt 310 and a nut 320. The bolt 310 passes through the clamping member 200 and the connecting frame 100 in sequence from one side of the clamping member 200, and the nut 320 is located on the side of the connecting frame 100 away from the clamping member 200 and is fixedly connected to the bolt 310.

[0052] When assembling the pulley clamp 10 of this embodiment, when the angle steel is placed in an "L" shape, the clamping member 200 can be first placed on the upper side of the angle steel. At this time, the clamping member 200 can be lapped on the upper side of the angle steel under the action of gravity, which is convenient for positioning. Then, the connecting frame 100 is placed on the lower side of the angle steel and corresponds to the clamping member 200. Subsequently, the bolt 310 is passed through the connecting hole and the adjusting hole in sequence, and a nut 320 is connected to the end of the bolt 310 to fix the clamping member 200 and the connecting frame 100 to the angle steel. The structure is simple and the assembly is convenient.
