Description

Technical Field

[0001] The invention belongs to the field of floating dock approach bridge equipment, and in particular relates to a universal approach bridge for a ship and an installation method thereof. Background Art

[0002] The so-called pontoon is a rectangular flat-bottomed boat without a power device, usually fixed to the shore and used as a floating dock (the principle of the floating dock is as follows Figure 7 As shown in the figure, it is used for loading and unloading goods or for pedestrians to get on and off. In the existing floating dock, the approach bridge (generally a steel approach bridge) connecting the pontoon to the shore is connected by hard friction on the plane through a semicircular tube, and a certain gap is reserved around the semicircular tube. As the pontoon floats up and down and forward and backward, the steel approach bridge uses the gap to adjust the horizontal and vertical angles. This solution can solve the connection problem between the pontoon and the shore in some waters, but due to the limited adjustable angle, it is not suitable for waters with large water level differences (requiring a larger vertical swing angle for the steel approach bridge) and large horizontal displacement of the ship (requiring a larger vertical swing angle for the steel approach bridge). And because of the hard friction method, it causes greater damage to the hull, which is not conducive to safety. Summary of the invention

DETAILED DESCRIPTION

[0024] The preferred solution is Figures 1 to 6 As shown, a universal approach bridge for a ship comprises an approach bridge body 1, one end of which is provided with a steering device, the steering device comprises a base 2, a turntable 3 is provided above the base 2, and the turntable 3 is connected to the base 2 through a rotating shaft 11; a transverse beam column 4 is provided on the turntable 3, and the transverse beam column 4 is connected to a U-shaped groove plate 5, and the U-shaped groove plate 5 is connected to the approach bridge body 1. The steering device is used to realize the horizontal rotation and up and down angle adjustment of the approach bridge body 1. When the pontoon is located in a water area with a large water level drop and a large horizontal displacement of the ship, the approach bridge body 1 will not cause friction between the approach bridge body 1 and the pontoon due to the movement of the pontoon, thereby protecting the connection point between the pontoon and the approach bridge body 1 and preventing the pontoon from being worn.

[0025] Furthermore, if Figures 2 to 4 As shown, the U-shaped groove plate 5 is detachably connected to the safety plate 7, and the safety plate 7 is provided with an arc groove. After the safety plate 7 is connected to the U-shaped groove plate 5, the arc groove and the U-shaped groove plate 5 clamp the transverse beam column 4. When the arc groove and the U-shaped groove plate 5 clamp the transverse beam column 4, the approach bridge body 1 will not be separated from the transverse beam column 4 when the pontoon floats up and down. The U-shaped groove plate 5 is detachably connected to the safety plate 7 to facilitate the connection or separation of the approach bridge body 1 and the steering device.

[0026] Furthermore, if Figure 3 As shown, the insurance plate 7 is provided with a plurality of screw holes, and the insurance plate 7 is connected to the U-shaped groove plate 5 by fixing screws. Figure 3 and Figure 4 In the figure, the insurance plate 7 and the transverse beam 4 seem to be connected together, but the insurance plate 7 and the transverse beam 4 are not fixedly connected, but only in contact; this is a position effect diagram displayed to facilitate the viewing of the insurance plate 7.

[0027] Furthermore, if Figure 4As shown, annular grooves 401 are provided at both ends of the transverse beam column 4; the U-shaped groove plate 5 includes a U-shaped groove, which is placed on the annular groove 401 of the transverse beam column 4 from top to bottom, and the arc groove of the safety plate 7 is sleeved on the annular groove 401 from bottom to top. The annular groove 401 is a circle of grooves opened on the surface of the transverse beam column 4, and the U-shaped groove plate 5 and the safety plate 7 clamp the annular groove 401, so that the U-shaped groove plate 5 is not easy to slide, thereby improving the stability of the approach bridge body 1.

[0028] Furthermore, a support wheel 6 is provided on the lower surface of the turntable 3, and the support wheel 6 contacts the upper surface of the base 2. The support wheel 6 mainly supports the weight of the approach bridge body 1. The approach bridge body 1 has a relatively large mass. While supporting the approach bridge body 1, the support wheel 6 makes the approach bridge body 1 rotate more smoothly, avoiding large friction between the turntable 3 and the rotating shaft 11.

[0029] Preferably, there are two supporting wheels 6, and the centers of the two supporting wheels 6 and the rotating disk 3 are located on the same straight line.

[0030] Furthermore, a sleeve 8 is provided at the center of the lower surface of the rotating disk 3, a copper sleeve 9 is provided inside the sleeve 8, a tetrafluoroethylene anti-wear bushing 10 is provided inside the copper sleeve 9, and the tetrafluoroethylene anti-wear bushing 10 is sleeved on the rotating shaft 11. The copper sleeve 9 and the tetrafluoroethylene anti-wear bushing 10 are used to avoid hard friction between the sleeve 8 and the rotating shaft 11, thereby preventing the sleeve 8 and the rotating shaft 11 from being worn.

[0031] Furthermore, the rotating shaft 11 is fixedly connected to the base 2; the stop bolt 12 is vertically arranged to penetrate the axis of the rotating disk 3, the screw portion of the stop bolt 12 is threadedly connected to the rotating shaft 11, and a gap is provided between the nut of the stop bolt 12 and the upper surface of the rotating disk 3. The stop bolt 12 prevents the rotating disk 3 from being separated from the base 2. At the same time, the stop bolt 12 cannot connect the rotating disk 3 to the base 2 too tightly to prevent the rotating disk 3 from being unable to rotate.

[0032] In a preferred solution, the installation method of the ship universal approach bridge comprises the following steps:

[0033] S1: Fixing the base 2 of the steering device on the deck of the pontoon;

[0034] S2: Put the copper sleeve 9 on the rotating shaft 11, and then put the polytetrafluoroethylene anti-wear bushing 10 on the copper sleeve 9;

[0035] S3: Sleeve the sleeve 8 on the lower surface of the turntable 3 onto the tetrafluoroethylene anti-wear bushing 10;

[0036] S4: Insert the U-shaped groove plate 5 at one end of the bridge approach body 1 into the annular groove 401 from top to bottom, insert the safety plate 7 into the annular groove 401 from bottom to top, and connect the U-shaped groove plate 5 and the safety plate 7 with bolts. The other end of the bridge approach body 1 (with rollers installed) is placed on the base bank 14.

[0037] The working principle of the whole device is as follows:

[0038] The steering device can realize the lateral and vertical rotation of the approach bridge body 1. The specific steering principle is: the turntable 3 rotates around the rotating shaft 11. After the U-shaped groove plate 5 is connected to the transverse beam column 4, the approach bridge body 1 can rotate around the rotating shaft 11, which can meet the needs of horizontal movement of the pontoon 13; when the arc groove of the safety plate 7 and the U-shaped groove plate 5 clamp the transverse beam column 4, the approach bridge body 1 can realize the up and down angle adjustment, which can meet the up and down floating needs of the pontoon 13.
