Description

Technical Field

[0001] The utility model relates to the technical field of vehicle auxiliary tools, in particular to a bridge plate device. Background Art

[0002] When an in-vehicle equipment detection vehicle is operating outdoors, it is often necessary to move large-scale detection equipment from the vehicle to the ground. However, due to the heavy weight of the detection equipment and a certain lifting height at the rear of the vehicle, the difficulty of equipment movement is increased. Sometimes, due to site and condition limitations, it is not convenient to use a forklift, resulting in obstacles to equipment movement, thus bringing inconvenience to the detection work. Summary of the Utility Model

[0003] In view of the above situation, it is necessary to provide a bridge plate device to solve the problem of equipment movement restricted by site and conditions in the prior art.

[0004] A bridge plate device is used in cooperation with a vehicle. The bridge plate device includes a bridge plate and a fixed base from top to bottom. The fixed base is fixedly connected to the vehicle floor, and the bridge plate is movably connected to the fixed base.

[0005] Two parallel rollers are provided at the bottom of the bridge plate. The two rollers extend along the length direction of the bridge plate. A first bearing assembly is provided between the two rollers. The first bearing assembly includes a first bearing bracket, a first bearing, and a first coupling shaft. The first bearing bracket is provided at one end of the bottom of the bridge plate. The first bearings are provided on both sides of the first bearing bracket. The first bearings are connected to the first bearing bracket through the first coupling shaft.

[0006] The fixed base is a frame structure. The fixed base includes two C-shaped steel channels and several vertical shafts. The two ends of the vertical shafts are respectively connected to the two C-shaped steel channels. Several rollers are provided at the top of the vertical shafts. The rollers are adapted to the rollers. The two C-shaped steel channels are adjacent to the first bearing. The two C-shaped steel channels extend along the length direction of the fixed base. The first bearing is in rolling connection with the upper inner sides of the two C-shaped steel channels. A gap is formed between the first bearing and the lower inner sides of the two C-shaped steel channels. A limiting portion is provided at one end of the fixed base. The height of the top of the limiting portion is higher than the height of the top of the bridge plate. A stop block is provided at the other end of the fixed base. The stop block is adapted to the first coupling shaft.

[0007] When the utility model is in use, the device to be moved and detected is placed and fixed on the bridge plate, and the bridge plate is moved to drive the detection device to move. The roller slides along the length direction of the fixed base on the roller, and the bearing slides along the C-shaped steel channel. Due to the presence of the C-shaped steel channel, the bearing is restricted from detaching from the C-shaped steel channel, so that the bridge plate is separated from the fixed base. A gap is formed between the lower part of the bearing and the inner lower part of the C-shaped steel channel. This is the safety gap, which restricts the bridge plate from moving within a certain range in the vertical direction on the fixed base. When the bridge plate is about to move out of the fixed base, the stop block abuts against the first coupling shaft to restrict the bridge plate from separating from the fixed base. The bridge plate gradually approaches and fits with the ground. At this time, the device is completely on the slope formed by the bridge plate and the ground, and the device can be moved out by manpower or a trailer;

[0008] When retracting, lift the bridge plate so that both ends of the bridge plate are in a horizontal state, push the bridge plate to release the limit of the first coupling shaft by the stop block, and continue to push the bridge plate until the end of the bridge plate is flush with the end of the fixed base. The limiting part abuts against the bridge plate to continue moving, making it relatively fixed;

[0009] The utility model is simple to operate, can be used and taken at any time, is not restricted by the site and conditions, greatly improves the efficiency of moving the detection device, and brings convenience to the detection work.

[0010] Further, square tubes are symmetrically arranged at the bottom of the bridge plate. The two square tubes are respectively arranged on one side of the two C-shaped steel channels facing away from the first bearing, and the square tubes extend along the length direction of the bridge plate.

[0011] For the utility model, the main function of the square tube is to limit the left and right movement freedom of the bridge plate, prevent the bridge plate from separating from the fixed base, and at the same time increase the bearing strength of the bridge plate.

[0012] Further, a second bearing assembly is also arranged between the two rollers. The second bearing assembly includes a second bearing bracket and a second bearing. The second bearing bracket is arranged at one end of the fixed base facing away from the first bearing bracket, and the second bearings are arranged on both sides of the second bearing bracket.

[0013] For the utility model, by using the first bearing assembly and the second bearing assembly, when the bridge plate moves on the fixed base, the bridge plate does not separate from the fixed base from above.

[0014] Further, buckle locks are arranged on both sides of one end of the fixed base. The buckle locks are adjacent to the stop block. The buckle locks are used to lock the bridge plate and the fixed base after the end of the bridge plate overlaps with the end of the fixed base.

[0015] Further, an inclined surface part is arranged on the top of the bridge plate. The inclined surface part is arranged above the second bearing bracket and is used to fit with the ground.

[0016] Further, a plurality of handles are provided on both sides of the top of the bridge plate, the handles are adjacent to the inclined surface portion, and the handles are used to pull the bridge plate.

[0017] Further, the axes of the rollers are respectively at the same height as the axes of the first bearing and the second bearing.

[0018] Further, a plurality of buckles are provided on both sides of the top of the bridge plate, and the buckles are used to connect the rope binding device.

[0019] Further, the materials of the bridge plate and the fixed base are both stainless steel. Description of the Drawings

[0031] Specifically, as Figures 1 to 3As shown, one end of the top of the bridge plate 1 is provided with an inclined surface portion 14. The inclined surface portion 14 is located above the second bearing bracket 132. The inclined surface portion 14 is used to fit with the ground. A plurality of buckles 16 are provided on both sides of the top of the bridge plate. The buckles 16 are used to connect the rope binding device. A plurality of handles 17 are provided on both sides of the top of the bridge plate 1. The handles 17 are adjacent to the inclined surface portion 14. The handles 17 are used for the user to pull the bridge plate 1.

[0032] Specifically, as Figures 1 to 4 , the fixed base 2 is of a frame structure and includes two C-shaped steel channels 22 and a plurality of vertical shafts 21. Both ends of the vertical shaft 21 are respectively connected to the two C-shaped steel channels 22. A plurality of rollers 211 are provided on the vertical shaft. The roller shaft 11 is adapted to the rollers 211. On both sides of the top of the fixed base 2, C-shaped steel channels 22 are symmetrically provided. The two C-shaped steel channels 22 are adjacent to the first bearing 121. The two C-shaped steel channels 22 extend along the length direction of the fixed base 2. The upper parts of the first bearings 121 are respectively in rolling connection with the upper inner sides of the two steel channels 22. The lower parts of the first bearings 121 respectively form a gap with the lower inner sides of the two C-shaped steel channels 22. One end of the bottom of the fixed base 2 is provided with a limiting portion 23. The height of the top of the limiting portion 23 is higher than the height of the top of the bridge plate 1. The other end of the bottom of the fixed base 2 is provided with a stop block 24. The stop block 24 is adapted to the first coupling shaft 14.

[0033] Specifically, Figures 1 to 3 As shown, buckle locks 25 are provided on both sides of one end of the fixed base 2. The buckle locks 25 are adjacent to the stop block 24 and are provided on both sides of the stop block 24. The buckle locks 25 are used to lock the bridge plate 1 and the fixed base 2 after the end of the bridge plate 1 overlaps with the end of the fixed base 2.

[0034] Specifically, Figure 2 As shown, the axes of the rollers 211 are respectively at the same height as the axes of the first bearings 121 and the second bearings 131.

[0035] Specifically, the materials of the bridge plate 1 and the fixed base 2 are both stainless steel.

[0036] In the present utility model, the main function of the square tube 14 is to limit the left and right movement freedom of the bridge plate 1, prevent the bridge plate 1 from separating from the fixed base 2, and at the same time increase the bearing strength of the bridge plate 1.

[0037] In the present utility model, during use, as Figure 1 , Figure 4 and Figure 5As shown in the figure, first unlock the buckle lock 25, then place the detection device to be moved and fix it on the bridge plate 1 with a rope through the buckle 16. Move the bridge plate 1 by using the handle 17 to drive the detection device to move. The roller 11 slides along the length direction of the fixed base 2 on the roller 211. The first bearing 121 and the second bearing 131 slide along the C-shaped channel steel 22. Due to the existence of the C-shaped channel steel 22, it restricts the first bearing 121 and the second bearing 131 from detaching from the C-shaped channel steel 22, so that the bridge plate 1 is separated from the fixed base 2. A clearance is formed between the lower parts of the first bearing 121 and the second bearing 131 and the inner lower part of the C-shaped channel steel 22. This is the safety clearance, which restricts the bridge plate 1 from moving within a certain range in the vertical direction on the fixed base 2. When the bridge plate 1 is about to move out of the fixed base 2, the stop block 24 of the fixed base 2 abuts against the first coupling shaft 14 to restrict the bridge plate 1 from separating from the fixed base 2. Since the axes of the rollers 211 are respectively at the same height as the axis of the first bearing 121 and the axis of the second bearing 131, it ensures that the bridge plate slides smoothly relative to the fixed base. When the bridge plate and the fixed base are relatively separated, the bridge plate 1 rotates around the axis of the roller 211. The bridge plate 1 gradually approaches the ground. When the inclined surface part 14 makes the bridge plate 1 fit with the ground, the detection device is completed and is on the slope formed by the bridge plate 1 and the ground. The detection device can be moved out by manpower or a trailer.

[0038] When retracting, lift the bridge plate 1 so that both ends of the bridge plate 1 are in a horizontal state. Push the bridge plate 1 by using the handle 17 to release the limit of the stop block 24 on the first coupling shaft 14. Continue to push the bridge plate 1 by using the handle 17 until the bridge plate 1 is flush with the end of the fixed base 2. Then lock the bridge plate 1 and the fixed base 2 with the buckle lock 25.

[0039] The utility model has the advantages of simple operation, being available for use at any time, not being restricted by sites and conditions, greatly improving the moving efficiency of the detection device, and bringing convenience to the detection work.
