DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. The present invention is further described below in conjunction with the embodiments.

[0036] See also Figure 1-Figure 5 In one embodiment of the present application, a connection device for bridge assembly includes a connection seat 1, an intermediate seat 7, two groups of sliding seats 6, and a connection arm 11. The number of the connection seats 1 is two and they are symmetrically arranged on both sides of the intermediate seat 7. Each connection seat 1 is provided with a group of sliding seats 6, and each group of sliding seats 6 is symmetrically arranged on the connection seat 1. The intermediate seat 7 is movably connected to the connection seat 1 through the connection arm 11. The connection seat 1 is U-shaped. The connection device also includes:

[0037] The splint 2 is symmetrically formed with a groove 3 on the connecting seat 1, and the splint 2 is movably arranged in the groove 3 and the two are elastically connected;

[0038] An adjusting module is provided between the sliding seat 6 and the clamping plate 2. When the sliding seat 6 moves, the position of the clamping plate 2 in the groove 3 can be adjusted by the adjusting module;

[0039] A first limiting structure is provided between the sliding seat 6 and the connecting seat 1 and is used to fix the position of the sliding seat 6 on the connecting seat 1; and

[0040] The second limiting structure is arranged between the intermediate seat 7 and the connecting seat 1 and is used to fix the position of the intermediate seat 7 on the connecting seat 1.

[0041] In a specific case of this embodiment, an inclined portion 24 is symmetrically formed on the connecting seat 1 .

[0042] In another specific case of this embodiment, the adjustment module includes:

[0043] The hollow tubes 20 are arranged in a group and symmetrically on the connecting base 1. The connecting base 1 is provided with an air groove 23 connected to the hollow tubes 20. The air groove 23 is connected to the groove 3 through the air hole 22.

[0044] A piston 21 is movably disposed in the hollow tube 20 and elastically connected thereto; and

[0045] The push rod 10 is connected between the sliding seat 6 and the piston 21.

[0046] It should be noted that the position of the clamping plate 2 in the groove 3 is not limited to being adjusted by the above-mentioned adjustment module, and can also be replaced by a linear motor or an electric cylinder, which are not listed here one by one.

[0047] In actual application, the two bridge plates are respectively inserted into the connecting seats 1 on both sides of the middle seat 7. By controlling the two bridge plates to move toward each other, or controlling one bridge plate to move toward the other bridge plate, the sliding seat 6 is moved along the connecting seat 1 toward the direction of the hollow tube 20. At this time, under the action of the push rod 10, the air in the hollow tube 20 can be squeezed into the air groove 23 and enter the groove 3 along the air hole 22, driving the splint 2 to move along the groove 3 until the surface of the splint 2 and the bridge plate are tightly fitted, thereby achieving the clamping and fixing of the bridge plate. At the same time, since the splicing between the two connecting seats 1 is completed, The connection work can be carried out by effectively fixing the position of the sliding seat 6 on the connecting seat 1 and the position of the fixed seat on the connecting seat 1 through the first connecting structure and the second connecting structure, thereby completing the connection and fixation work between the two bridge plates. The whole process is highly automated. It is only necessary to control the movement between the bridge plates to control the stable clamping of the bridge plates by the connecting seat 1 and the fixation work between the connecting seats 1. There is no need for staff to use external tools to tighten the bolts to perform the fixation work between the bridge plates, which reduces the manpower input, speeds up the connection speed between the bridges, and shortens the connection cycle between the bridges.

[0048] See also Figure 1-Figure 3 As another preferred embodiment of the present application, the first limiting structure includes a limiting head 9 and a limiting hole 4. The limiting head 9 is movably arranged on the sliding seat 6 and the two are elastically connected. The limiting hole 4 is arranged on the connecting seat 1 and is located on the moving path of the limiting head 9.

[0049] In this embodiment, the second limiting structure includes a locking head 17, a plurality of locking strips 18 and a through hole 5;

[0050] A locking head 17 is symmetrically arranged on the fixing seat, the through hole 5 is formed on the connecting seat 1 and is located on the moving path of the locking head 17, and several locking strips 18 are symmetrically arranged on the locking head 17. One end of the locking strip 18 is hinged to the locking head 17 and a torsion spring is provided at the hinge. A limiting portion 19 is provided on one side of each locking strip 18 on the locking head 17.

[0051] When the connecting seats 1 move closer to each other, the sliding seat 6 is driven to move along the connecting seat 1, and the middle seat 7 moves toward the connecting seat 1. When the limit head 9 on the sliding seat 6 meets the limit hole 4 on the connecting seat 1, the elastic restoring force between the limit head 9 and the sliding seat 6 causes the limit head 9 to be inserted into the limit hole 4, completing the fixing of the position of the sliding seat 6 on the connecting seat 1. At the same time, the locking head 17 is inserted into the through hole 5, and the middle seat 7 can be fixed to the connecting seat 1 through the locking strip 18, thereby completing the fixing work between the two connecting seats 1, so that the splicing and fixing work between the two bridges is completed.

[0052] See also Figure 1 、 Figure 2 as well as Figure 4 As another preferred embodiment of the present application, the connecting device further includes a monitoring module, which is arranged between the connecting base 1 and the fixing base, and is used to monitor the installation progress of the fixing base and the connecting base 1.

[0053] In this embodiment, the monitoring module includes:

[0054] The slider 14 is movably disposed in the guide groove 12 formed on the connecting arm 11, and the slider 14 is movably connected to the connecting base 1 through the driving arm 16;

[0055] A first conductive sheet 13 is provided on the inner wall of the guide slot 12;

[0056] The second conductive sheet 15 is disposed on the slider 14 , and the first conductive sheet 13 is located on the moving path of the second conductive sheet 15 ; and

[0057] The plug 8 is disposed on the intermediate base 7 , and the plug 8 , the first conductive sheet 13 , and the second conductive sheet 15 are electrically connected.

[0058] It should be noted that this embodiment is not limited to the above-mentioned conductive sheet 13 and conductive sheet 15 for monitoring the position of the slider 14 in the guide groove 12. Infrared ranging sensors or laser ranging sensors can also be used instead, which are not listed here one by one.

[0059] Before connecting the two bridges, connect the plug 8 to the external detection instrument. When the fixed seat moves toward the connecting seat 1 so that the sliding seat 6 moves synchronously, the angle between the connecting arm 11 and the sliding seat 6 changes. As a result, under the action of the slider 14 and the driving arm 16, the slider 14 moves along the guide groove 12 until the No. 1 conductive piece 13 and the No. 2 conductive piece 15 are in contact, indicating that the fixed connection between the two connecting seats 1 is completed. At this time, the plug 8 is used to feedback to the external detection instrument, and the staff can remotely know the installation and splicing progress of the bridge.

[0060] How this application works:

[0061] The two bridge plates are respectively inserted into the connecting seats 1 on both sides of the middle seat 7. By controlling the two bridge plates to move toward each other, or controlling one bridge plate to move toward the other bridge plate, the sliding seat 6 is moved along the connecting seat 1 toward the direction of the hollow tube 20. At this time, under the action of the push rod 10, the air in the hollow tube 20 can be squeezed into the air groove 23 and enter the groove 3 along the air hole 22, driving the splint 2 to move along the groove 3 until the surface of the splint 2 and the bridge plate are tightly fitted to achieve the clamping and fixing of the bridge plate. At the same time, when the limit head 9 on the sliding seat 6 meets the limit hole 4 on the connecting seat 1, the elastic restoring force between the limit head 9 and the sliding seat 6 causes the limit head 9 to be inserted into the limit hole 4, completing the fixing of the position of the sliding seat 6 on the connecting seat 1. At the same time, the locking head 17 is inserted into the through hole 5, and the middle seat 7 can be fixed to the connecting seat 1 through the locking strip 18, thereby completing the fixing work between the two connecting seats 1, so that the splicing and fixing work between the two bridges is completed. The entire process is highly automated. It is only necessary to control the movement between the bridge plates to control the stable clamping of the bridge plates by the connecting seat 1 and the fixing work between the connecting seats 1. There is no need for staff to use external tools to tighten the bolts to fix the bridge plates, which reduces the input of manpower, speeds up the connection speed between bridges, and shortens the connection cycle between bridges. Before connecting the two bridges, the plug 8 is connected to the external detection instrument. When the fixed seat moves toward the connecting seat 1 so that the sliding seat 6 moves synchronously, the angle between the connecting arm 11 and the sliding seat 6 changes. As a result, under the action of the slider 14 and the driving arm 16, the slider 14 moves along the guide groove 12 until the No. 1 conductive sheet 13 and the No. 2 conductive sheet 15 are in contact, indicating that the fixed connection between the two connecting seats 1 is completed. At this time, the plug 8 is used to feedback to the external detection instrument, and the staff can remotely know the progress of the installation and splicing of the bridge.
