Figure 1-5As shown, it includes a bridge frame body, which includes two oppositely arranged bridge frame side panels 1, and the bottom of the inner end surface of the bridge frame side panel 1 is provided with an extension plate 101 integrally formed therewith, wherein a plurality of evenly distributed fixing columns 102 are provided at the bottom of one bridge frame side panel 1, and a sliding groove 107 is provided at one end of the fixing column 102 away from the bridge frame side panel 1, and a sliding rod 103 with one end fixedly connected to the other bridge frame side panel 1 is slidably connected in the sliding groove 107, and a plurality of equidistantly distributed fixing frames 2 are detachably provided between the two bridge frame side panels 1.

[0025] Among them, a guide block 104 adapted to the guide groove 203 is provided on the inner end surface of the bridge side plate 1. The setting of the guide block 104 and the guide groove 203 improves the connection strength between the fixing frame 2 and the two bridge side plates 1.

[0026] Among them, the sliding rod 103 is symmetrically provided with limit columns 112 on both sides of one end close to the fixed column 102, and the fixed column 102 is symmetrically provided with limit grooves 106 on both sides for the displacement of the limit columns 112. The limit grooves 106 are connected with the sliding groove 107. Through the setting of the limit grooves 106 and the limit columns 112, the displacement of the sliding rod 103 in the sliding groove 107 can be limited.

[0027] Furthermore, the slide bar 103 is penetrated by a first connecting hole 111 for inserting a connecting bolt, and the fixing column 102 is provided with a second connecting hole 109 for receiving the slide bar 103 in the slide slot 107 and communicating with the first connecting hole 111. The second connecting hole 109 cooperates with the first connecting hole 111 to provide the connecting bolt, so that the slide bar 103 can be received in the slide slot 107 to fix the two bridge frame side plates 1 between them, avoiding displacement between the two bridge frame side plates 1 during transportation.

[0028] Furthermore, a reinforcement block 105 that can be inserted into the reinforcement groove 204 is provided on the top end face of the extension plate 1101. Through the setting of the reinforcement block 105 and the reinforcement groove 204, the stability of the connection between the fixing frame 2 and the two bridge frame side plates 1 is further improved. A second fixing hole 110 connected to the first fixing hole 206 is opened through the extension plate 101 on one side of the reinforcement block 105. The second fixing hole 110 and the first fixing hole 206 are matched with the setting of the fixing bolt 3, thereby improving the tightness of the fixing frame 2 installed between the two bridge frame side plates 1.

[0029] refer to Figure 5 The fixing frame 2 shown in the figure includes a supporting plate 201 with a long rectangular structure, and reinforcement grooves 204 with a cross-shaped structure are symmetrically opened on both sides of the bottom end surface of the supporting plate 201. Mounting plates 205 are symmetrically welded at both ends of one side of the supporting plate 201. A first fixing hole 206 for inserting the fixing bolt 3 is opened through the mounting plate 205. Connecting columns 202 are symmetrically provided on both sides of the top of the supporting plate 201, and a guide groove 203 with a trapezoidal structure is opened on the outer end surface of the connecting column 202.

[0030] The working principle and operation steps of the utility model are as follows:

[0031] When the bridge needs to be transported, the fixing bolts 3 inserted into the first fixing hole 206 and the second fixing hole 110 are first removed, so that the staff can remove the fixing frame 2 from between the two bridge frame side plates 1. Then, the connecting bolts inserted into the first connecting hole 111 and the third connecting hole 108 are removed, and the slide bar 103 is slid and stored in the slide groove 107, so that the two bridge frame side plates 1 are close to each other. When the slide bar 103 is completely slid and stored in the slide groove 107, the first connecting hole 111 on the slide bar 103 is connected with the second connecting hole 109 on the fixing column 102. The connecting bolts are inserted into the connected first connecting hole 111 and second connecting hole 109 to fix them, thereby avoiding displacement between the two bridge frame side plates 1 during transportation. The utility model reduces the transportation space occupied during transportation by splitting the bridge frame body into multiple components, thereby improving the loading and unloading efficiency of the staff.

[0032] When the bridge needs to be assembled, first remove the connecting bolts inserted in the first connecting hole 111 and the second connecting hole 109, pull the slide bar 103 to slide it out of the slide slot 107, so that the first connecting hole 111 on the slide bar 103 is connected to the third connecting hole 108 on the fixing column 102, insert the connecting bolts into the connected first connecting hole 111 and the third connecting hole 108 to fix them, so that the two bridge side plates 1 after adjustment are fixed and limited, and multiple fixing frames 2 are inserted from between the tops of the two bridge side plates 1. Press-fit, align the guide groove 203 on the fixing frame 2 with the guide block 104 on the bridge side plate 1 and insert them, and at the same time, the reinforcement block 1105 on the extension plate 101 is inserted into the reinforcement groove 204 on the fixing frame 2, so that the first fixing hole 206 on the mounting plate 205 is connected with the second fixing hole 110 on the extension plate 101, and the fixing bolt 3 is inserted into the connected first fixing hole 206 and second fixing hole 110 to fix them, thereby installing the fixing frame 2 between the two bridge side plates 1, and completing the assembly of the bridge.
