[0018] Example

[0019] Combination Figure 1-3 An improved ladder-type bridge that is easy to use is shown, including a bridge body, the bridge body includes two symmetrically arranged side panels 1, a plurality of equally spaced support panels 2 are arranged between the two side panels 1, a plurality of downwardly recessed first receiving grooves 201 are provided on the top end surface of the support panel 2, a rotatable roller 202 is provided at the bottom of the first receiving groove 201, and the cables on the bridge body can be placed separately by the first receiving groove 201 and the roller 202 in the first receiving groove 201, while avoiding the influence on other cables in the bridge body when one of the cables is repaired and replaced at a later stage, a docking groove 203 is provided on the top end surface of the support panel 2 between the two adjacent first receiving grooves 201, and the docking groove 203 is in a cross-shaped structure, and first grooves 203 for plugging in the fastening bolts 4 are symmetrically provided on both sides of the support panel 2. A connecting hole 204, a fixing plate 3 is detachably provided on the top of the support plate 2, and a second accommodating groove 301 corresponding to the first accommodating groove 201 is provided on the bottom end surface of the fixing plate 3. The cable placed on the support plate 2 can be fixed by setting the fixing plate 3 and the second accommodating groove 301 on the fixing plate 3, thereby ensuring the stability of the cable on the bridge frame body. A docking column 302 that matches the docking groove 203 is provided on the bottom end surface of the fixing plate 3 between two adjacent second accommodating grooves 301. The docking groove 203 is matched with the docking column 302, thereby improving the connection strength between the support plate 2 and the fixing plate 3. The docking column 302 and the fixing plate 3 are connected by welding, thereby improving the connection strength between the docking column 302 and the fixing plate 3. Guide grooves 303 with a T-shaped structure are symmetrically provided on both sides of the fixing plate 3.

[0020] A guide block 101 matching the guide groove 303 is disposed on the inner wall of the side plate 1 . The guide block 101 matches the guide groove 303 , so that the guide block 101 can play a guiding role when the fixing plate 3 and the supporting plate 2 are installed.

[0021] The fixing plate 3 is provided with a second connection hole 304 which is in communication with the first connection hole 204 , and the second connection hole 304 and the first connection hole 204 are internal threaded holes with the same structure and size.

[0022] The roller 202 is provided with a rubber pad on its exterior, and the rubber pad on the roller 202 is provided to avoid damage to the cable protective layer when the cable is pulled.

[0023] The implementation principle of the utility model is:

[0024] When laying cables, the cables are placed one by one on the roller 202 in the first accommodating groove 201, and then the fixing plate 3 is press-fitted from the top of the support plate 2. During press-fitting, the guide groove 303 on the fixing plate 3 is aligned with the guide block 101 on the inner wall of the side plate 1 for guided insertion. While inserting, the docking column 302 at the bottom of the fixing plate 3 is inserted into the docking groove 203 on the support plate 2. At this time, the first connecting hole 204 on the support plate 2 is connected with the second connecting hole 304 on the fixing plate 3. The fastening bolt 4 is inserted into the first connecting hole 204 and the second connecting hole 304 to complete the connection between the support plate 2 and the fixing plate 3. When the cable is pulled out for maintenance and replacement, the pulled cable will drive the roller 202 to rotate, so that the staff can pull the cable more smoothly and reduce the pulling resistance. At the same time, during the pulling process, the rubber pad on the roller 202 will reduce the friction between the cable and the roller 202, thereby protecting the protective layer of the cable.

[0025] 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.

[0026] 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.
