Description
Technical Field
[0001] The utility model relates to the technical field of trailers, and particularly to a marine waterproof trailer. Background Art
[0002] During the manufacturing, water testing and maintenance of ships, it is often necessary to move the ship from land to water or from water to land. Since the volume and length of the ship are relatively large, it is difficult to move. Therefore, currently, the movement of the hull is often achieved through a lifting device or a mobile trailer.
[0003] Due to the complex structure, high cost and difficult maintenance of the lifting device, it is more cost-effective to use a mobile trailer for the land-water transfer of inland ships. The main method of using a mobile trailer for the land-water transfer of inland ships is as follows: fix the mobile trailer in the shipyard. When the shipyard and the mobile trailer are both underwater, the inland ship sails into the shipyard; after stopping stably, the shipyard drains water and rises, lifting the inland ship out of the water, and then pulling the mobile trailer to realize the movement of the inland ship. Therefore, during the land-water transfer of the inland ship, the mobile trailer needs to be immersed in water for a long time, and water has certain corrosiveness, which will corrode the wheel bearings of the mobile trailer, resulting in poor rotational flexibility of the wheels or even failure.
[0004] Therefore, it is very necessary for this field to carry out waterproof design on the bearings of marine mobile trailers. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the defects of the prior art and provide a marine waterproof trailer.
[0006] To achieve the above purpose and other purposes, the utility model is realized by including the following technical solutions: The utility model provides a marine waterproof trailer, which includes a vehicle frame and at least four wheels. The wheels are arranged inside the vehicle frame, and the bottom of the wheels exposes the bottom of the vehicle frame. The wheels include a roller shaft fixedly arranged on the vehicle frame; a roller sleeved on the roller shaft through a bearing; a sealing pressing plate sleeved on the roller shaft and located on both sides of the bearing; and a retaining ring sleeved on the roller shaft, located outside the sealing pressing plate and pressing the sealing pressing plate, so as to form a sealing cavity between the sealing pressing plate, the roller shaft, the bearing and the inner ring of the roller, and sealing oil is contained in the sealing cavity.
[0007] In one embodiment, the material of the bearing is tin bronze.

[0031] In order to avoid confusion with the present utility model, some well-known technical features in the art are not described.
[0032] As Figures 1-4 shown, the present utility model provides a marine waterproof trailer 100, which includes a frame 110 and at least four wheels 120. The wheels 120 are arranged within the frame 110, and the bottom thereof protrudes from the bottom of the frame 110. The wheels 120 include rollers 121, roller shafts 122, bearings 123, sealing pressing plates 124, and retaining rings 125. The roller shafts 122 are fixedly arranged on the frame 110; the rollers 121 are sleeved on the roller shafts 122 through the bearings 123; the sealing pressing plates 124 are sleeved on the roller shafts 122 and are located on both sides of the bearings 123; the retaining rings 125 are sleeved on the roller shafts 122 and are located outside the sealing pressing plates 124 and press the sealing pressing plates 124, so as to form a sealing cavity 1241 between the sealing pressing plates 124 and the roller shafts 122, bearings 123, and the inner rings of the rollers 121. The sealing cavity 1241 can accommodate sealing oil, so that the bearings 123 are in a sealed state, thereby ensuring that when the marine waterproof trailer 100 is flooded, the bearings 123 do not come into contact with water and are not corroded by water, and thus the service life is extended.
[0033] Furthermore, the material of the bearings 123 can be tin bronze, which has good elasticity and wear resistance, and can ensure that the rollers 121 can still roll stably under relatively large pressure.
[0034] Furthermore, the sealing pressing plates 124 can be marine rubber plates, and the width of the sealing cavity 1241 formed thereby can reach 1 cm, and they are inexpensive and suitable for shafts of any size.
[0035] Furthermore, the rollers 121 can be rubber wheels or track wheels. Figure 4 The roller 121 shown in
[0036] is a track wheel with grooves provided on the axial plane. Figure 1 and 2 Furthermore, in order to prevent the paint surface of the ship from being scratched by the metal frame 110, cushion blocks 130 can be provided on the upper end surface of the frame 110. The cushion blocks 130 have a certain rigidity and elasticity and can be wooden blocks or rubber blocks. The number of the cushion blocks 130 can be two as shown in
[0037] As Figure 1And 2 As shown in 2 , traction rings 140 are further provided on the front and rear sides of the vehicle frame 110 for threading ropes to apply a traction force to the vehicle frame 110 to pull the marine waterproof trailer 100 for movement.
[0038] As Figure 5 As shown in Figure 5 , when the ship 200 is a sharp-bottomed ship, in order to ensure that the marine waterproof trailer 100 can stably support the ship 200, at least two brackets 150 can be provided on the upper end surface of the vehicle frame 110. The brackets 150 are symmetrically arranged on the left and right sides of the upper end surface of the vehicle frame 110. The bracket 150 includes a first telescopic arm 151, a second telescopic arm 152, a third telescopic arm 153, and a support plate 155. The fixed ends of the first telescopic arm 151, the second telescopic arm 152, and the third telescopic arm 153 are sequentially installed on the upper end surface of the vehicle frame 110 from the inside out; the movable ends of the first telescopic arm 151 and the second telescopic arm 152 are commonly connected to one end of the support plate 155, and the movable end of the third telescopic arm 153 is separately connected to the other end of the support plate 155. The design of the bracket 150 can achieve adaptive adjustment of height and angle according to the bottom shape of the ship 200.
[0039] Furthermore, the first telescopic arm 151, the second telescopic arm 152, and the third telescopic arm 153 can be hydraulic telescopic rods, which have the characteristics of large output force and high load, can ensure stable support of ships with relatively large mass, and are more reliable and safe than pneumatic telescopic rods.
[0040] Furthermore, in order to prevent the paint surface of the ship 200 from being scratched by the metal support plate 155, a cushion block 156 can be fixedly provided on the support plate 155. The cushion block 156 has a certain stiffness and elasticity and can be a wooden block or a rubber block.
[0041] Therefore, the utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the utility model and are not used to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the utility model should still be covered by the claims of the utility model.
