Description

Technical Field

[0001] This utility model relates to the field of bridge-type ship unloading, and in particular to a bridge-type ship unloading device for cement handling. Background Technology

[0002] A bridge-type unloading device is a piece of equipment used for unloading cargo in a port. It typically consists of a boom, a conveyor belt, and a support structure. It can be moved above the location of a cargo ship, using the boom to grab the cargo and then transporting it from the ship to the dock via the conveyor belt.

[0003] While existing technologies can achieve certain effects in lifting and transporting cement, they have drawbacks: the existing bridge-type unloading devices lack multi-functional lifting capabilities and the ability to adaptively adjust the overall lifting effect when lifting cement objects. This leads to an imbalance in the device's center of gravity during lifting and transportation, making it prone to tipping over or stress concentration on one side of the weighed objects, resulting in damage and accidents. In view of this, we propose a bridge-type unloading device for cement handling that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a bridge-type unloading device for cement handling.

[0005] The technical solution of this utility model is as follows: A bridge-type unloading device for cement handling includes a mounting frame, a guide rail one, a guide rail three, a guide rail two, and a damper. The guide rail one is fixedly installed on one side of the mounting frame, and a moving block one is installed inside the guide rail one. The guide rail three is fixed on one side of the upper end of the mounting frame, and a moving block two is provided inside the guide rail three. The guide rail two is fixed on one side of the moving block two, and a winch two is provided inside the guide rail two. A lead screw one is provided at the lower end of the mounting frame, and a housing is rotatably connected to the outer wall of the lead screw one. A damper is suspended at the lower end of the housing.

[0006] This device offers two lifting methods. The first method involves slow, direct transport of heavier objects using a winch that drives a movable block within a fixed-stroke guide rail. The second method utilizes a second guide rail (which moves within a third guide rail) on one side of the first guide rail to extend the transport depth using a winch. However, this method cannot handle excessively heavy objects. The two lifting methods can be switched depending on the specific circumstances. When using one method, the damper at the bottom of the mounting frame moves to the other side, stabilizing the overall center of gravity and preventing it from shifting to the other side during lifting, which could lead to collapse.

[0007] Preferably, a fixing frame is fixed at the lower end of the mounting bracket, the lead screw is rotatably mounted between the fixing frames, and a limit rod is fixed between the fixing frames.

[0008] Preferably, a servo motor is fixed to one side of the outer wall of the fixed frame, and the output shaft of the servo motor is fixedly connected to the rotation center of one side of the lead screw.

[0009] Preferably, a bracket is fixed to the lower end of the mounting frame, and a base is fixed to the lower end of the bracket.

[0010] Preferably, a winch is fixed to one side of the inside of the guide rail, and a guide wheel is rotatably installed on the other side of the inside of the guide rail. A torsion spring is provided on one side of the guide wheel. The rope inside the winch is fixed to the moving block, and the rope wound inside the guide wheel is fixed to the other side of the moving block. A winch is provided at the lower end of the moving block, and a clamping arm is provided at the lower end of the winch.

[0011] Preferably, a lead screw is rotatably mounted inside the guide rail, and the winch is rotatably connected to the lead screw.

[0012] Preferably, the second movable block is equipped with a second servo motor, the output shaft of the second servo motor is rotatably connected to the second lead screw, the second movable block is equipped with a rotary motor, the outer wall of the second movable block is rotatably mounted with a roller, and the roller is rolled inside the guide rail three. The output shaft of the rotary motor is fixedly connected to the rotation center of one side of the roller, and a control console is fixed at the upper end of the mounting frame.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This utility model can use a fixed-length guide rail one to achieve the hoisting and conveying effect of large objects, and use an adjustable conveying depth guide rail two to achieve the hoisting effect of lighter objects. The two can be used alternately to provide users with more options.

[0015] Second, based on the first beneficial effect, when this device is hoisted on one side, the center of gravity on one side is easily offset. In case of some accidents, the device may overturn. Therefore, during hoisting, the damper will move to the other side to neutralize the center of gravity and ensure that it is in the center, thus ensuring the safe use of the device.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-5As shown, this embodiment is a bridge-type unloading device for cement handling, including a mounting frame 1, a guide rail 1 23, a guide rail 3 5, a guide rail 2 8 and a damper 12. The guide rail 1 23 is fixedly installed on one side of the mounting frame 1. A moving block 1 6 is installed inside the guide rail 1 23. The guide rail 3 5 is fixedly installed on one side of the upper end of the mounting frame 1. A moving block 2 4 is provided inside the guide rail 3 5. The guide rail 2 8 is fixedly installed on one side of the moving block 2 4. A winch 2 9 is provided inside the guide rail 2 8. The lower end of the mounting frame 1 is provided with a lead screw 16. A housing 15 is rotatably connected to the outer wall of the lead screw 16. The damper 12 is suspended at the lower end of the housing 15.

[0030] This device has two hoisting methods. The first method is to slowly transport heavy objects directly using a winch to drive the moving block 6 inside the fixed-stroke guide rail 23 to achieve the hoisting effect. The second method is to use a guide rail 8 on one side of the guide rail 23, which can move inside the guide rail 3 5, to achieve the conveying effect of the winch 9, which can extend the conveying depth. However, this method cannot hoist objects with excessive weight. The two hoisting methods can be switched according to the actual situation. When hoisting in one of the methods, the damper 12 located at the lower end of the mounting frame 1 will move to the other side, so that the center of gravity of the overall device is stabilized and will not be offset to the other side due to hoisting, which could easily cause collapse.

[0031] Example 2

[0032] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: a fixed frame 18 fixed at the lower end of the mounting frame 1, a lead screw 16 rotatably mounted between the fixed frames 18, a limit rod 17 fixed between the fixed frames 18, and a housing 15 inserted into the limit rod 17. The limit rod 17 can ensure the stable movement of the housing 15.

[0033] A servo motor 19 is fixed to one side of the outer wall of the mounting bracket 18. The output shaft of the servo motor 19 is fixedly connected to the rotation center of the lead screw 16. Under the action of the control console 2, the servo motor 19 can drive the lead screw 16 to rotate, thereby adjusting the damping 12 at the lower end of the mounting bracket 1 and ensuring the stability of the center of gravity.

[0034] The mounting bracket 1 has a support 13 fixed at the lower end, and a base 11 is fixed at the lower end of the support 13. The support 13 and the base 11 can increase the stability of the device. The support 13 has high rigidity, can support heavy objects, and has high toughness, making it less prone to breakage.

[0035] A winch 3 is fixed to one side of the guide rail 23, and a guide wheel 21 is rotatably mounted on the other side of the guide rail 23. A torsion spring 22 is provided on one side of the guide wheel 21. The rope inside the winch 3 is fixed to the moving block 6. The rope wound inside the guide wheel 21 is fixed to the other side of the moving block 6. A winch 3 is provided at the lower end of the moving block 6, and a clamping arm 10 is provided at the lower end of the winch 3. The torsion spring 22 can wind up the rope when the winch 3 is released. This effect can be used in conjunction with the winch 3 to drive the moving block 6 to move inside the guide rail 23. The clamping arm 10 at the lower end of the moving block 6 is a common mechanical gripper for holding objects, which will not be described in detail. The moving block 6 also has a hoisting winding device inside, which will not be described in detail.

[0036] Inside the guide rail 28, a lead screw 27 is rotatably installed. The winch 29 is rotatably connected to the lead screw 27. The servo motor 20 can drive the lead screw 27 to rotate, thereby adjusting the movement of the winch 29 inside the guide rail 28. The lower end of the winch 29 is also equipped with a hoisting rope and a clamping hand, which are not shown in the diagram here.

[0037] The movable block 24 is equipped with a servo motor 20 inside. The output shaft of the servo motor 20 is rotatably connected to the lead screw 27. The movable block 24 is also equipped with a rotary motor 14 inside. Rollers are rotatably mounted on the outer wall of the movable block 24 and are rolled inside the guide rail 35. The output shaft of the rotary motor 14 is fixedly connected to the rotation center on one side of the roller. The upper end of the mounting frame 1 is fixed with a control console 2. The rotary motor 14 can drive the rollers to rotate, thereby adjusting the movement of the movable block 24 inside the guide rail 35 and adjusting the lateral length of the guide rail 28, which is convenient for hoisting objects at more distant positions.
