As introduced by the background art, the conventional cable support is easy to cause cable slipping to injure personnel, the cable is stopped by the stop block, the defect that the cable is blocked is overcome, the conventional cable support comprises a large number of cross arms, the fixed cross arms are labor-and time-consuming, and the cable erection requires multiple persons to participate in so as to waste a large amount of labor.

Example 1

An exemplary embodiment of the present application, as shown in fig. 1-6, provides a quick mount bracket for a subway cable.

Referring to fig. 1-6, the present embodiment provides a rapid subway cable mounting bracket, which includes a slide rail 1, a bearing member 2 and a stop member 3; the sliding rail is a square cylinder with a through groove at one side;

the bearing piece comprises a sliding block 21 and a cross arm 22, and one end of the cross arm is fixed on the side wall of the sliding block; the sliding block is clamped inside the sliding rail, the cross arm penetrates through the through groove and protrudes out of the sliding rail, and the sliding block can slide relative to the sliding rail; the sliding block is a square cylinder with hole plugging plates 23 arranged at two ends, and a through groove is formed in one side of the sliding block;

the stop piece comprises a stop block 31 and a stop rod 32, wherein the stop block is a rectangular block with two ends provided with a guy cable 33, and one end of the stop rod is fixed on the side wall of the stop block; the stop block is clamped inside the sliding block, the stop rod penetrates through the through groove and protrudes out of the sliding block, and the stop block can slide relative to the sliding block; the inhaul cable passes through the opening of the sliding block plugging plate.

By arranging the plugging plates with holes at two ends of the sliding block, the guy cable of the stop block can extend out of the plugging plates, and the stop block is abutted with the plugging plates after the guy cable is tensioned so as to transfer the tensile force to the sliding block, so that the bearing member can be moved along with the pulling of the guy cable; further, the support and the stop members are all provided with a plurality of, the support and the stop members are arranged in one-to-one correspondence, and the stop members are connected with each other through the inhaul cable, so that the inhaul cable can drive the support members to act together.

It can be understood that, the backstop piece sets up the both ends of cable, indicates the both ends that the backstop piece is in the inside time of sliding block and is not contacted with the sliding block inner wall, through set up the cable at the both ends of backstop piece, makes two adjacent backstop pieces can be connected through the cable, and then makes the lifting motion of cable can apply to a plurality of support pieces in step.

Since this embodiment aims to avoid a large number of workers lifting the cable, the cable should be set up on the cross arm at a position close to the ground as much as possible; specifically, the length of the sliding rail set in the embodiment is equal to the distance from the target setting height of the cable to the road surface of the tunnel, so that a constructor can finish cable erection only by slightly lifting the cable, and the labor burden of the constructor is reduced;

considering that the subway cable is thicker, when the inhaul cable is not tensioned, the supporting pieces are stacked together, the distance between the cross arms is possibly insufficient, and the cable is not convenient to set up; in this embodiment, the upper end of the sliding block is higher than the cross arm by increasing the sliding block, so that a sufficient cross arm interval can be reserved when the sliding blocks are mutually abutted, and the power cable enters.

Furthermore, the sliding rail can be matched with the wall surface of the tunnel to form an arc shape; because the tunnel is high inside, local curvature is less, even the slide rail agrees with wall surface radian also can not interfere the normal slip of bearing piece.

In order to prevent the bearing piece from being separated from the sliding rail, the upper end of the sliding rail is provided with a locking plate 11, and the upper end of the sliding rail is one end of the sliding rail which is far away from a tunnel pavement after being installed in place; in this embodiment, in order to facilitate the mounting of the support member into the slide rail, the lower end of the slide rail is not provided with a stopper, and the support member may be mounted inside the slide rail from the lower end of the slide rail.

Considering that the setting of the stop block can affect the erection of the cable, the cross arm provided by the embodiment comprises two straight plates which are arranged in parallel and have the same setting height; the cross arms also comprise bottom plates 24, wherein the bottom plates are rectangular plates, two sides of the bottom plates are connected with the bottoms of the two cross arms in a one-to-one correspondence manner, and the bottom plates and the cross arms jointly enclose a space for accommodating the stop rod;

in the embodiment, the side surface of the long side of the bottom plate is connected with the bottom of the cross arm;

further, referring to fig. 5, the cross arm is provided with a plurality of groups of arc grooves 25 at intervals, and each group of arc grooves comprises two arc grooves which are oppositely arranged on two straight plates; the stop rod comprises a plurality of stop blocks 34 which are arranged at intervals, and the arrangement intervals of the stop blocks are equal to the arrangement span of the arc-shaped groove; when the inhaul cable is not tensioned, the stop block of the stop rod is completely contained in the space clamped by the two straight plates, so that the stop block cannot prevent the cable from being erected, and the cable erected with the cross arm naturally slides into the arc-shaped groove to be initially fixed; when the inhaul cable is tensioned, the stop block slides in the sliding block, so that the stop block is lifted, and a stop effect on the cable sliding into the arc-shaped groove is formed.

It is understood that, in order to ensure that the stopper can be completely accommodated in the space surrounded by the bottom plate and the cross arm, the distance from the top of the stopper to the bottom of the stopper rod is smaller than the distance from the top of the bottom plate to the top of the cross arm.

Example 2

As shown in fig. 7, the present embodiment provides a rapid subway cable installation system, which includes a plurality of rapid subway cable installation brackets, a connecting rod 4 and a winch 5; the winch is fixed on the inner wall of the tunnel; one side of the connecting rod is connected with the guy ropes of the plurality of subway cable quick installation brackets, and one side of the connecting rod, which is away from the guy ropes, is connected with the guy ropes of the winch; the quick subway cable installation system provided by the embodiment realizes the lifting of the inhaul cables of the quick subway cable installation brackets through one connecting rod, and the cables are lifted in place after being lifted by the winch;

further, for fixing the connecting rod, a plurality of fixing pieces 41 are arranged at intervals on the connecting rod, and the position of the connecting rod is fixed by the fixing pieces, so that the locking of the position of the cable can be completed; specifically, the fixing member may be a stainless steel tube clip.
