Utility model content

The purpose of this utility model is to provide a balance device for working boat transfer, which can solve one or more of the above-mentioned problems in the prior art.

According to one aspect of the utility model, a balance device for transferring a working boat is provided, including a boom and a balance bracket, the boom can lift the working boat, the balance bracket is movably arranged on the boom, and the balance bracket can fix the working boat. The boom is provided with a driving device, which can drive the balance bracket to expand or retract.

In some embodiments: the balance bracket includes a V-shaped connecting rod and two balance rods respectively arranged at the two free ends of the V-shaped connecting rod, and a space between the ends of the two balance rods not connected with the V-shaped connecting rod is formed for the entry of the working boat. The middle part of the V-shaped connecting rod is hinged to the boom. Thus, the balance bracket can be sleeved on one end of the working boat to fix the working boat and maintain its balance.

In some embodiments: rubber pads are provided on the inner surfaces of the V-shaped connecting rod and the balance bar. Thereby, it is possible to prevent the work boat from being worn by the balance bracket.

In some embodiments: the driving device is an oil cylinder or an air cylinder, the bottom of the driving device is hinged to the boom, and the free end of the driving device is hinged to the balance bracket. Thereby, the balance support can be driven to expand or retract.

In some embodiments: the boom is provided with a winch, a fixed pulley and a controller, the winch is wound with a wire rope, and the free end of the wire rope is connected to the working boat around the fixed pulley, the fixed pulley is provided with a pressure sensor, and the pressure sensor can measure the pressure of the wire rope. The pressure of the pulley is fixed, and the pressure signal is sent to the controller, which is electrically connected to the winch. Therefore, in the actual transfer process of the working boat, the bow and the stern of the working boat are respectively hoisted by two booms to transfer the working boat. At this time, the pressure of the steel wire rope on the fixed pulley can be detected by the pressure sensor, and then the When the tension of the wire rope is small, the controller controls the winch to tighten the wire rope so that the tension of the wire rope reaches a constant value, so that the tension of the two wire ropes at the bow and stern of the working boat is the same; on the contrary, when the tension of the wire rope is relatively large, The controller controls the winch to loosen the wire rope, so that the tension of the wire rope reaches a constant value, so that the tension of the two wire ropes at the bow and stern of the working boat is the same. It can not only reduce the impact of waves on the boat when the boat enters and leaves the water, but also keep the boat level, which improves the comfort of the boat and reduces the chance of damage to equipment due to impact.

The utility model is provided with a balance support on the boom, and the balance support can be sleeved on one end of the working boat to fix it, prevent it from shaking, and keep its balance.

Detailed ways

Below in conjunction with accompanying drawing description, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a balance device for transfer of working boats includes a boom 1 and a balance bracket 2, the boom 1 can lift the workboat, the balance bracket 2 is movably arranged on the boom 1, and the balance bracket 2 can fix the working boat, the boom 1 is provided with a driving device 3, and the driving device 3 can drive the balance bracket 2 to expand or retract. Thus, by setting the balance bracket on the boom, the balance bracket can be sleeved on one end of the working boat to fix it, prevent it from shaking, and keep it balanced.

Wherein, the balance bracket 2 includes a V-shaped connecting rod 21 and two balance rods 22 fixedly connected to the two free ends of the V-shaped connecting rod 21 respectively, and an opening between the ends of the two balance rods 22 that are not connected with the V-shaped connecting rod 21 is formed for The opening 23 where the working boat enters, and the middle part of the V-shaped connecting rod 21 is hinged to the boom 1. Thus, the balance bracket can be sleeved on one end of the working boat to fix the working boat and maintain its balance. In addition, in another embodiment, the V-shaped connecting rod 21 can be composed of two connecting rods, the ends of the two connecting rods can be connected by a torsion spring, and the balance bar 22 and the V-shaped connecting rod 21 are also connected by a torsion spring. Connected, thus, when the balance bracket 2 is clipped on the end of the work boat, the balance bracket 2 can be clamped to the work boat by the torsion spring, so as to further maintain the balance of the work boat.

In addition, rubber pads 24 are fixed on the inner surfaces of the V-shaped connecting rod 21 and the balance bar 22 . Thereby, it is possible to prevent the work boat from being worn by the balance bracket.

Wherein, the driving device 3 is an oil cylinder or an air cylinder, in this embodiment it is an oil cylinder, the bottom of the driving device 3 is hinged to the boom 1 , and the free end of the driving device 3 is hinged to the balance bracket 2 . Thereby, the balance support can be driven to expand or retract.

In addition, the boom 1 is also fixedly installed with a winch 11, a fixed pulley 12 and a controller 13. The winch 11 is wound with a wire rope 14, and the free end of the wire rope 14 is fixedly connected to the bow or stern of the working boat by going around the fixed pulley 12. The pulley 12 is provided with a pressure sensor 15, the pressure sensor 15 can measure the pressure of the steel wire rope 14 on the fixed pulley 12, specifically, the pressure sensor 15 is installed between the fixed pulley 12 and the boom 1, and the pressure signal is sent to the controller 13. The controller 13 is electrically connected to the winch 11. Therefore, in the actual transfer process of the working boat, the bow and the stern of the working boat are respectively hoisted by two booms to transfer the working boat. At this time, the pressure of the steel wire rope on the fixed pulley can be detected by the pressure sensor, and then the When the tension of the wire rope is small, the controller controls the winch to tighten the wire rope so that the tension of the wire rope reaches a constant value, so that the tension of the two wire ropes at the bow and stern of the working boat is the same; on the contrary, when the tension of the wire rope is relatively large, The controller controls the winch to loosen the wire rope, so that the tension of the wire rope reaches a constant value, so that the tension of the two wire ropes at the bow and stern of the working boat is the same. It can not only reduce the impact of waves on the boat when the boat enters and leaves the water, but also keep the boat level, which improves the comfort of the boat and reduces the chance of damage to equipment due to impact.

In addition, an angular displacement sensor 16 can also be installed in the rotating shaft of the winch 11. The angular displacement sensor can measure the number of turns of the winch, and send the signal to the controller 13, and then calculate the length of the wire rope 14 released by the winch 11. By controlling The device 13 controls the winch 11 so that the length of the wire rope 14 released by the two booms 1 is always, thus keeping the balance at both ends of the working boat.
