[0023] Example

[0024] Combination Figure 1-6 A cable bridge that is easy to maintain is shown, including a bridge body and a supporting assembly 4 arranged in the bridge body, the bridge body includes a bridge cover 1 with a long rectangular structure, and bridge side panels 2 extending along the length direction are symmetrically arranged on both sides of the bottom of the bridge cover 1, one of the bridge side panels 2 is provided with a fixed plate 7 at the bottom of the outer side, and a bridge bottom plate 3 parallel to the bridge cover 1 is provided between the bottoms of the two bridge side panels 2.

[0025] Combination Figure 4-5 As shown, an inspection groove 301 is provided on one side of the bridge bottom plate 3, and an inspection plate 8 is slidably connected in the inspection groove 301. Guide plates 801 with a T-shaped structure are symmetrically provided on both sides of the inspection plate 8. A sealing plate 804 is provided on one side of the inspection plate 8 and is integrally formed therewith. A mounting plate 802 extending along its length direction is provided on the other side of the inspection plate 8. A plurality of evenly distributed first mounting holes 803 for plugging in fastening bolts 5 are provided on the top end face of the mounting plate 802. By matching the inspection groove 301 on the bridge bottom plate 3 with the inspection plate 8, there is no need for staff to climb to a height higher than the bridge body for inspection, thereby improving the convenience for staff to inspect and maintain the cables inside the bridge body.

[0026] The inspection groove 301 has guide grooves 302 symmetrically provided on both sides thereof for the guide plates 801 to be plugged in. The guide grooves 302 are matched with the guide plates 801 to improve the connection strength between the inspection plate 8 and the bridge frame bottom plate 3.

[0027] The bridge bottom plate 3 is provided with a sealing groove 303 for the sealing plate 804 to be inserted into. The sealing plate 804 and the sealing groove 303 are arranged to improve the sealing between the inspection plate 8 and the bridge bottom plate 3 .

[0028] like Figure 3 The support assembly 4 shown in the figure comprises a load-bearing plate 401 with an arc-shaped structure, and connecting plates 402 fixedly connected to the inner walls of the bridge side plates 2 are symmetrically arranged on both sides of the load-bearing plate 401, and the connecting plates 402 and the load-bearing plate 401 are an integrally formed structure, and a plurality of hanging racks 403 for hanging cables are arranged at the bottom of the load-bearing plate 401. By setting the hanging racks 403 at the bottom of the load-bearing plate 401, the cables can be placed separately, and it is convenient for the staff to open the inspection panel 8 to inspect the cables.

[0029] A reinforcing column 6 is provided at the connection between the connecting plate 402 and the bridge frame side plate 2 . The cross section of the reinforcing column 6 is a triangular structure. By providing the reinforcing column 6 , the connection strength between the support assembly 4 and the bridge frame body is improved.

[0030] like Figure 6 The fixing plate 7 shown in the figure has a mounting groove 701 on the outer bottom side of the fixing plate 7 to which the top of the mounting plate 802 can be clamped, and a second mounting hole 702 which is connected one-to-one with the first mounting hole 803 is formed through the top end face of the fixing plate 7, and the second mounting hole 702 and the first mounting hole 803 are internal threaded holes with the same structural dimensions, and the first mounting hole 803 on the mounting plate 802 and the second mounting hole 702 on the fixing plate 7 are matched with each other, thereby improving the connection strength between the inspection plate 8 and the bridge frame body.

[0031] The working principle of the utility model of a cable bridge which is easy to maintain:

[0032] When performing maintenance, the staff first loosens the fastening bolts 5 and pulls the inspection plate 8 out from the bridge bottom plate 4, so that the inspection plate 8 is disconnected from the bridge bottom plate 4. The inspection groove 301 on the bridge bottom plate 4 is matched with the inspection plate 8, so that the staff does not need to climb to a height higher than the bridge body for maintenance, which improves the convenience of the staff to inspect and maintain the cables inside the bridge body. When the inspection plate 8 is pulled out, the cables hoisted on the hanging parts 403 at the bottom of the load-bearing plate 401 are exposed, and the staff inspects the cables inside the bridge body through the inspection groove 301.

[0033] After the inspection is completed, the guide plate 801 on the inspection plate 8 is plugged into the guide grooves 302 on both sides of the inspection groove 301. When the guide plate 801 is plugged into the bottom of the guide groove 302, the sealing plate 804 on the inspection plate 8 is plugged into the sealing groove 303 on the bridge frame bottom plate 3, and the mounting plate 802 on the inspection plate 8 is plugged into the mounting groove 701 on the fixed plate 7. At this time, the first mounting hole 803 is connected to the second mounting hole 702, and the fastening bolts 5 are inserted into the first mounting hole 803 and the second mounting hole 702 for fixed connection, so that the inspection plate 8 is installed at the bottom of the bridge frame body.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
