Abstract
Description
Technical Field
[0001] The utility model relates to the field of dock launching, and particularly to a launching structure for a dock gate. Background Art
[0002] In the prior art, the launching of large dock gates usually relies on hoisting methods. Although this method is widely used in small and medium-sized dock gates, for the launching of large dock gates, airbags are mostly used. However, in traditional airbag launching, each airbag is relatively independently arranged. This independent arrangement may lead to different relative positions and inflation states between airbags, thus causing the problem of airbag offset. The offset of the airbag will affect the overall stability of the dock gate, making it possible to tilt or settle unevenly during the launching process. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the problem in the prior art that when the airbags are separately arranged, it is easy for one of the airbags to offset, resulting in the offset of the sliding direction of the entire dock gate, and to provide a launching structure for a dock gate.
[0004] In a first aspect, the utility model provides a launching structure for a dock gate. This structure is used for the dock gate to be launched on a slope and includes a traction device. The traction device is fixed to the ground and the other end is connected to the dock gate. A transportation device is provided at the lower end of the dock gate, and the transportation device is an integrally splicable component.
[0005] The traction device is used to limit and control the sliding of the dock gate.
[0006] The transportation device realizes the launching of the dock gate.
[0007] The utility model is a launching structure for a dock gate. By setting a traction device at one end of the dock gate to limit and control the sliding of the dock gate, and setting a transportation device at the lower end of the dock gate. While transporting the dock gate through the transportation device, and then limiting the dock gate through the traction device, the launching process of the entire dock gate becomes smoother. Then, the entire transportation device is set as an integrally splicable component, which can not only adapt to dock gates of different sizes, but also ensure that the transportation device will not offset during the transportation process, avoiding the offset of the entire dock gate during the sliding process due to the change of force, and improving the accuracy of the dock gate sliding.
[0008] Preferably, the transportation device includes a plurality of rollers arranged at intervals. Connecting and adapting devices are provided at both ends of the rollers, and adjacent rollers are detachably connected through the connecting and adapting devices.
[0009] Through such a setting method, the operator can adjust the size of the transportation device according to the size of the dock gate, and connect multiple rollers to form a transportation device that can provide uniform support and bearing capacity for the dock gate, ensuring stability during transportation.
[0010] Preferably, the main body of the connection and adaptation device is a connecting rod. A connection groove is provided at one end of the connection and adaptation device, and an adapter is provided at the other end of the connection and adaptation device. The connection groove of one roller is connected to the adapter of another roller.
[0011] Ensure that it can be quickly installed and removed during on-site construction, improving construction efficiency.
[0012] Preferably, the roller includes a barrel body. An inflatable airbag is provided outside the barrel body. An air inlet is provided on the inflatable airbag. The transportation device is connected with an inflation device, and the inflation device is communicated with each inflatable airbag.
[0013] By arranging an inflatable airbag outside the roller, when the dock gate is subsequently lowered, it can play a role in jacking up the dock gate, so that the dock gate does not contact the abutment pier, realizing the lowering of the dock gate.
[0014] Preferably, abutment piers are provided at both ends of the roller. Each abutment pier abuts against the bottom of the dock gate. The height of the abutment pier is H, and the height of the roller when the inflatable airbag is not inflated is h1. When the dock gate has not been lowered, H > h1.
[0015] In this way, when the inflatable airbag is not inflated, the dock gate can ensure that it does not contact the ground through the abutment piers at the bottom. At the same time, through the setting of the abutment piers, the operator can have enough space to install the transportation device and adjust the position of the transportation device.
[0016] Preferably, abutment piers are provided at both ends of the roller. Each abutment pier abuts against the bottom of the dock gate. The height of the abutment pier is H, and the height of the roller when the inflatable airbag is inflated is h2. When the dock gate is lowered, H < h2.
[0017] After the inflatable airbag is inflated, the height of the roller is higher than the height of the abutment pier, so that the dock gate can be jacked up by the inflatable airbag, so that the bottom of the dock gate does not contact the abutment pier, facilitating the operator to evacuate the abutment pier in time and preparing for the subsequent lowering of the dock gate into the water. At the same time, due to the self-weight of the dock gate, when the inflatable airbag contacts the dock gate and jacks it up, the contact surface between the dock gate and the inflatable airbag increases, ensuring a large stress area between the dock gate and the inflatable airbag and more uniform stress.
[0018] Preferably, the traction device includes a ground anchor. One end of the ground anchor is fixedly connected to the ground, and the other end is connected with a roller group.
[0019] Fixed to the ground by ground anchors, it ensures the stability of the system and prevents slipping or displacement during operation. The roller group connected to the other end of the ground anchor can smoothly transmit the traction force, reducing friction and resistance, making the movement of the dock gate smoother and more precise.
[0020] Preferably, a connecting cable is provided at one end of the roller group away from the ground anchor, and the connecting cables are respectively connected to both sides of the dock gate.
[0021] The connection between the roller group and the dock gate is achieved through the connecting cables, and these connecting cables are respectively connected to both sides of the dock gate, which helps to ensure the balance of the dock gate during movement and prevent it from tilting or being unstable.
[0022] Preferably, the roller group is a movable pulley group.
[0023] The movable pulley group can reduce the traction force by changing the direction of the force, thereby reducing the actual traction force required. This makes the operation more labor-saving and improves the overall efficiency.
[0024] Preferably, the traction device includes a winch, a steel wire rope is provided on the winch, the winch is connected to the roller group through the steel wire rope, and the winch realizes the tightening or loosening of the steel wire rope to control the movement of the roller group.
[0025] The winch can achieve precise movement control of the roller group by precisely controlling the tightening and loosening of the steel wire rope.
[0026] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0027] 1. The present utility model is a dock gate launching structure. This structure sets a traction device at one end of the dock gate to limit and control the sliding of the dock gate, and sets a transportation device at the lower end of the dock gate. While transporting the dock gate through the transportation device, the traction device limits the dock gate, making the entire launching process of the dock gate smoother. Then, the entire transportation device is set as a splicable integral part, which can not only adapt to dock gates of different sizes but also ensure that the transportation device will not shift during transportation, avoiding the deviation of the entire dock gate during the sliding process due to the change of the force, and improving the accuracy of the dock gate sliding.

[0040] Embodiment 1
[0041] As Figures 1 to 3 shown, a dock gate launching structure is used for launching the dock gate 5 when it is on a slope. The structure includes a traction device 1, which is connected to one end of the dock gate 5, and the other end of the traction device 1 is fixed to the ground to ensure that the dock gate 5 can receive a certain pulling force and will not rush into the water only by its own gravity, ensuring the safety of the construction site. A transport device 2 is provided at the lower end of the dock gate 5. The transport device 2 is composed of a plurality of rollers 21 spliced together, and the adjacent rollers 21 are detachably connected, which enables the operator to adjust the size of the transport device 2 according to the size of the dock gate 5 on site, increasing the adaptability of the transport device 2;
[0042] Furthermore, by connecting multiple rollers 21 into an integral transportation device 2, the rolling directions of each roller 21 can be ensured to be consistent, and the situation where the movement direction of a single roller 21 deviates will not occur, thus avoiding the deviation of the position of the dock gate 5 when it slides down.
[0043] In one or several embodiments, connection and adaptation devices 22 are provided at both ends of each roller 21. The body of the connection and adaptation device 22 is a connecting rod. The middle section of the connection and adaptation part 222 is connected to the axles at both ends of the roller 21, and the connection is a rotational connection. When the middle section of the connection and adaptation part 222 rotates around the axial direction of both ends of the roller 21, when the dock gate 5 is placed on several rollers 21, the rollers 21 can achieve self-rotation through the rotational connection between themselves and the connection and adaptation part 222.
[0044] Furthermore, a cross bar 212 is inserted in the axial direction of the roller 21. Connection and adaptation devices 22 are connected to both ends of the cross bar 212. The middle part of the connection and adaptation device 22 is connected to the end of the cross bar 212. One end of the connection and adaptation device 22 is an adaptation part 222, and the other end is a connection slot 221, and the connection slot 221 can be connected to the adaptation part 222.
[0045] When the operator assembles the rollers 21, the adjacent two rollers 21 are connected through the connection slot 221 and the adaptation part 222 (that is, the connection slot 221 of one roller 21 is connected to the adaptation part 222 of the adjacent roller 21). In this way, the operator can quickly complete the installation of the transportation device 2 on site. And compared with the traditional arrangement of multiple single air bags side by side, the transportation device 2 will not have the problem that the movement directions of each moving part (roller 21) are not fixed, resulting in the deviation of the route of the dock gate 5 being transported into the water and the failure of the launch, as Figures 2 to 3 shown.
[0046] In one or several embodiments, each roller 21 includes a barrel body 213. Inflatable air bags 211 are sleeved on the rolling surfaces of the barrel body 213, and each inflatable air bag 211 is provided with an inflation port.
[0047] Supports 4 are provided at both ends of each roller 21, and each support 4 is located in the lower area of the dock gate 5. The top of each support 4 abuts against the bottom surface of the dock gate 5, and the height of the support 4 is such that when the external inflatable air bag 211 of the roller 21 is not inflated, the height of the entire roller 21 is. If the dock gate 5 has not yet been launched at this time (that is, the bottom of the dock gate 5 still abuts against the top of the support 4), then this ensures that the entire dock gate 5 can be supported by several supports 4 to avoid the sudden sliding of the dock gate 5, and at the same time can ensure that the staff can adjust the transportation device 2.
[0048] When the dock gate 5 starts to slide down, the operator inflates each inflatable airbag 211 through the inflation device 3. At this time, the inflatable airbags 211 on each roller 21 bulge, and after contacting the bottom of the dock gate 5, the dock gate 5 is lifted. The height of the roller 21 after the inflatable airbag 211 is inflated is such that when the dock gate 5 starts to slide down, (that is, after the inflatable airbag 211 is inflated, the dock gate 5 is lifted, so that the bottom surface of the dock gate 5 does not contact the top of the abutment 4);
[0049] Further, after the dock gate 5 is lifted by the inflatable airbag 211, the operator removes each abutment 4 to avoid interference from the abutment 4 to the movement of the transport device 2. When the dock gate 5 slides down through the transport device 2, since the transport device 2 is an integral part composed of multiple rollers 21, during the sliding process, the rolling directions of the rollers 21 will not deviate, ensuring the sliding accuracy of the dock gate 5;
[0050] The dock gate 5 is always in contact with the inflatable airbag 211 during the sliding process, and the inflatable airbag 211 itself has a certain elasticity. During the sliding of the dock gate 5, its own gravity squeezes each inflatable airbag 211. At this time, the contact surface between the inflatable airbag 211 and the dock gate 5 deforms, increasing the contact area between the inflatable airbag 211 and the dock gate 5 and making the force more stable, as Figures 2 to 5 shown.
[0051] In a preferred embodiment, the traction device 1 includes an anchor 11 fixed to the ground. One end of the anchor 11 is firmly connected to the ground to ensure the stability of the system during operation and avoid sliding or displacement during the traction process. The other end of the anchor 11 is connected to a roller group 12. The roller group 12 can smoothly transmit the traction force in the way fixed by the anchor 11, significantly reducing the friction and resistance during the operation of the system, thus making the movement process of the dock gate 5 smoother and more accurate;
[0052] Further, one end of the roller group 12 away from the anchor 11 is connected to both sides of the dock gate 5 through a connecting cable 121. This design enables the connecting cable 121 to evenly distribute the torque during traction, ensuring that the dock gate 5 remains horizontal during the movement process and preventing tilting or instability.
[0053] In a preferred design, the roller group 12 is in the form of a movable pulley group. The movable pulley group changes the direction of the traction force, reducing the actual traction force required. This design reduces the physical effort consumed during operation, improves the efficiency of the overall traction operation, and makes the movement of the large dock gate 5 more labor-saving and fast, as Figure 1 shown.
[0054] In a preferred embodiment, the traction device 1 is equipped with a winch 13. The winch 13 is connected to the roller set 12 through a steel wire rope 131. By tightening or loosening the steel wire rope 131, the winch 13 can accurately control the moving position of the roller set 12. This design provides the control accuracy for the launching of the dock gate 5 and can accurately adjust the position of the dock gate 5, such as Figure 1 shown
[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
