[0025] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0026] like Figures 1 to 6 As shown, this embodiment proposes a cross-arm type cable bridge with a clamp, including a bridge and a cross-arm 3 arranged on the top of the bridge, a clamping assembly is arranged between the bridge and the cross-arm 3, the clamping assembly includes a reinforcing rib 7, a hoop plate 4 and a bolt 5, the hoop plate 4 includes a connecting plate 401 with an inclined structure, a first mounting portion 402 horizontally arranged at one end of the connecting plate 401 and a second mounting portion 403 vertically arranged at the other end of the connecting plate 401, the first mounting portion 402 and the surface of the cross-arm 3 are provided with a first positioning hole, the second mounting portion 403 and the reinforcing rib 7 and the surface of the bridge are also provided with a second positioning hole, the first positioning hole and the second positioning hole have the same structure and both cooperate with the bolt 5;

[0027] The bridge frame includes a frame body 1 and a cover plate 2 slidably arranged on the top of the frame body 1;

[0028] The cover plate 2 is clamped on the top of the frame 1, and then the cross arm 3 is placed on the top of the cover plate 2. At this time, the reinforcing rib 7 is abutted against the side wall of the frame 1, and a group of bolts 5 are passed through the frame 1, the reinforcing rib 7 and the second positioning hole on the second mounting portion 403, and then another group of bolts 5 are passed through the cross arm 3 and the first positioning hole on the first mounting portion 402. After that, nuts are put on the screw-in ends of the two groups of bolts 5. The frame 1, the cover plate 2 and the two ends of the cross arm 3 can be fixed. There is no need to hoop up the entire bridge frame body, which not only saves costs, but also avoids increasing the overall weight of the bridge frame, thereby improving the bearing capacity of the bridge frame.

[0029] like Figure 2 and Figure 7As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a receiving groove 701 is provided inside the side of the reinforcing rib 7, a clamping block 8 is slidably connected inside the receiving groove 701, a spring 9 is provided between the clamping block 8 and the inner bottom wall of the receiving groove 701, and a clamping groove 202 matching with the clamping block 8 is provided inside the side of the cover plate 2;

[0030] The end of the clamping block 8 away from the spring 9 is provided with an extrusion surface which is gradually inclined downward;

[0031] When the cover 2 is placed on the top of the frame 1, the side of the cover 2 will contact the block 8 and can squeeze the block 8 into the storage groove 701 through the extrusion surface to compress the spring 9. When the bottom of the cover 2 is completely against the top of the frame 1, the slot 202 on the side of the cover 2 will move to a position flush with the block 8. At this time, the spring 9 will be released from the force and drive the block 8 to rebound and reset. The block 8 will be bounced into the slot 202 to fix the cover 2. Therefore, when the cover 2 is placed on the frame 1, the two can be automatically fixed, further improving the stability of the cover 2.

[0032] In addition, a slide groove connected to the storage groove 701 is provided at the bottom of the side of the reinforcing rib 7, and a shift block 801 is provided at the bottom of the card block 8, which passes through the slide groove and extends outward; when the cover plate 2 needs to be removed, it is only necessary to pull the card block 8 back into the storage groove 701 through the shift block 801 to make the card block 8 disengage from the card slot 202, and the cover plate 2 will be loosened at this time, so that the cover plate 2 can be removed from the frame 1.

[0033] like Figure 2 and Figure 7 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, both sides of the bottom of the cross arm 3 are provided with limit blocks 6, and the top of the cover plate 2 is provided with a limit groove 201 matched with the limit block 6;

[0034] The limiting block 6 and the limiting groove 201 are T-shaped structures that cooperate with each other, and the limiting block 6 is made of rubber material;

[0035] When the crossarm 3 is placed on the cover plate 2, the limit block 6 at the bottom of the crossarm 3 will be inserted into the limit groove 201. At this time, the crossarm 3 is continued to be pressed downward, and the limit block 6 made of rubber will first be deformed and continue to slide down in the limit groove 201. When the crossarm 3 is completely against the cover plate 2, the limit block 6 will also be forcibly squeezed to the innermost part of the limit groove 201. At this time, the limit block 6 will rebound and restore its shape and overlap with the limit groove 201, so that the crossarm 3 and the cover plate 2 can be locked, further improving the stability of the entire bridge structure. When the crossarm 3 and the cover plate 2 need to be disassembled, it is only necessary to pull the crossarm 3 and the cover plate 2 with force. At this time, the limit block 6 will be deformed again under the force, so that the limit block 6 can be pulled out of the limit groove 201 to disassemble the crossarm 3 and the cover plate 2.

[0036] The working principle of the utility model is as follows: the cover plate 2 and the cross arm 3 are placed on the top of the frame body 1 in sequence, at this time, the reinforcing rib 7 is abutted against the side wall of the frame body 1, a group of bolts 5 are passed through the frame body 1, the reinforcing rib 7 and the second positioning hole on the second mounting portion 403, and then another group of bolts 5 are passed through the cross arm 3 and the first positioning hole on the first mounting portion 402, and then nuts are put on the screwed-in ends of the two groups of bolts 5 to fix the frame body 1, the cover plate 2 and the two ends of the cross arm 3, and there is no need to hoop up the entire bridge frame body, which not only saves costs but also avoids increasing the overall weight of the bridge frame, thereby improving the bearing capacity of the bridge frame; and when the cover plate 2 is placed on the frame body 1, the cover plate 2 and the frame body 1 can be automatically fixed by the cooperation of the spring 9 and the clamping block 8, and when the cross arm 3 is placed on the cover plate 2, the cross arm 3 and the cover plate 2 can be automatically fixed by the cooperation of the limit block 6 and the limit groove 201, thereby further improving the stability of the overall structure of the bridge frame.
