[0004] During the production process of the sampling unit and the discharge unit, it is necessary to manually carry the bracket to the sampling and discharge workbench, and then manually carry it to the pressing station after assembly. After pressing, it is manually carried to the finished product temporary storage area. The sampling and discharge unit weighs about 30kg after assembly. Manual handling can easily cause fatigue to personnel, posing a safety hazard.

[0005] The above-mentioned supporting modules were originally transported by crane, but since each team needs to use the crane, the waiting time of the crane is not fixed, the moving speed is slow, and two people are required to work together, so normal production hours cannot be guaranteed, resulting in low production efficiency and affecting work progress.

[0006] In order to meet market demand, the original supporting module lifting method is no longer suitable for the new process flow, and it is also impossible to guarantee normal production hours. In order to meet actual production needs, it is necessary to shorten the lifting and transportation time. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that, in this document, relational terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0026] Example 1

[0027] The embodiment of the present application provides a ship ballast water supporting module transfer device, which aims to solve the problem of low operating efficiency of the supporting modules during the transfer process; it is characterized by flexible mobility, reliable structure and convenient lifting, and is suitable for the lifting of industrial small and medium-sized supporting modules. The transfer device can reduce the use of personnel and vehicles, which can improve the work efficiency of the enterprise while reducing the labor intensity of employees.

[0028] Reference Figure 1The transfer device is a steel structure as a whole. The bottom of the transfer device is a walking base 1. The walking base 1 includes a fork frame 6. The fork frame 6 is located on both sides of the walking base 1. The lower surface of the fork frame 6 is 1-2 cm away from the ground. The fork frame 6 is used to be inserted under the tray where the supporting modules are placed. The walking base 1 is moved by manual pushing. The lifting mechanism 10, the battery 11 and the electric control system 12 are arranged in the middle of the transfer device. The crane arm 3 is arranged on the top of the transfer device for lifting the supporting modules.

[0029] Reference Figure 1 The end of the fork frame 6 facing the supporting module to be transported has an inclined surface 61, which helps the fork frame 6 to be smoothly inserted under the pallet. There is a hole next to the inclined surface 61, and the front wheel 7 is installed in the hole. The front wheel 7 is a directional wheel. The front wheel 7 protrudes 1-2 cm from the upper surface of the fork frame 6. The front wheel 7 is not only a walking wheel, but also has the function of assisting the supporting module to slide onto the upper surface of the fork frame 6, so that the fork frame 6 has the function of carrying and transporting the supporting module. For example, the fork frame 6 can be inserted into the bottom of the flat-bottomed supporting module, so that the supporting module can slide along the front wheel 7 onto the fork frame 6 for transportation.

[0030] Reference Figure 1 The walking base 1 also includes a rear wheel 8 at the bottom thereof, and the rear wheel 8 is a universal wheel; the side of the walking base 1 facing the supporting module to be transported is the front side, and the opposite rear side is the side where the person stands when pushing the walking base 1; the rear wheel 8 is located further back than the fork frame 6. A main frame 2 is fixed on the top of the walking base 1, and the main frame 2 includes two side panels and a reinforcing structure connected between the two side panels. The two side panels stand on both sides of the walking base 1, and a lifting mechanism 10, a battery 11 and an electric control system 12 are arranged between the two side panels. The battery 11 and the electric control system 12 are packaged in the same box for centralized management.

[0031] Reference Figure 1 The lifting mechanism 10 is preferably an electric hydraulic rod, the bottom end of which is hinged to the walking base 1, and the piston rod of the electric hydraulic rod is hinged upward to the lifting arm 3. The electric control system 12 is used to control the piston rod stroke of the electric hydraulic rod, and the battery 11 is used to power the electric control system 12 and the electric hydraulic rod.

[0032] Reference Figure 1 and Figure 2 The upper surface of the boom 3 has a through hole 31, which penetrates the upper and lower surfaces of the boom 3. The first pivot seat 16 is welded and fixed on the upper surface of the boom 3. The first pivot seat 16 has a pivot shaft 17. The piston rod of the electric hydraulic rod passes through the through hole 31 and is vertically fixedly connected to the pivot shaft 17. Since the load-bearing steel plates on both sides of the boom 3 are symmetrical about the piston rod of the electric hydraulic rod, the boom 3 can be evenly stressed; and the piston rod of the electric hydraulic rod will not protrude from one side of the boom 3, the operator's field of vision at the rear side of the boom 3 will not be blocked, the field of vision is wider, and the operation is more convenient.

[0033] Reference Figure 1 , one end of the boom 3 is hinged to the top or near the top of the main frame 2, and the other end is hinged to a hanger 13. A sling 5 is arranged on the hanger 13, and different supporting modules can be hoisted by replacing different slings 5. Commonly used slings 5 ​​are hooks and magnetic suction cups. The hanger 13 includes a sling mounting portion 131, a boom connecting portion 132 and a reinforcement portion 133, wherein the sling mounting portion 131 and the boom connecting portion 132 are welded and fixed perpendicularly to each other, and both ends of the reinforcement portion 133 are welded to the farthest end between the sling mounting portion 131 and the boom connecting portion 132, the sling mounting portion 131 is used to install the sling 5, the boom connecting portion 132 is located between the sling mounting portion 131 and the boom 3, the boom connecting portion 132 is hinged to one end of the boom 3 away from the main frame 2, and a telescopic rod 4 is hinged at the bottom of the boom connecting portion 132.

[0034] Reference Figure 1 The length of the telescopic rod 4 is adjustable. When the length of the telescopic rod 4 changes, the angle between the boom connection part 132 and the boom 3 changes accordingly, so that the inclination of the sling installation part 131 relative to the ground changes. Therefore, by changing the length of the telescopic rod 4, it can be suitable for hoisting different supporting modules. The telescopic rod 4 is formed by a screw rod 42 and an internal threaded sleeve 41 connected by threads. The internal threaded sleeve 41 is hinged to the main frame 2 below the boom 3. The hinge of the screw rod 42 and the hanger 13 is designed to be detachable. Before hoisting a supporting module, the hinge of the screw rod 42 and the hanger 13 is removed in advance, and the total length of the telescopic rod 4 is adjusted according to the supporting module. The adjustment method is to rotate the screw rod 42 relative to the internal threaded sleeve 41. After the adjustment is completed, the hinge of the screw rod 42 and the hanger 13 is reconnected, so that the sling installation part 131 can be tilted at a specific angle, so as to facilitate the hoisting of the supporting module.

[0035] Reference Figure 1 A pair of handles 9 are also fixed on the main frame 2. The handles 9 are located at the rear side of the main frame 2. A handle 9 is fixed on each side plate of the main frame 2, and the two handles 9 are symmetrical about the main frame 2. The height of the handles 9 is 50cm-100cm, preferably 60cm; when a person stands at the rear side and pushes the main frame 2, both hands can be naturally placed on the handles 9. For a 60cm high handle 9, when an adult of average height holds the handle 9, the angle between the upper arm (the part from the shoulder joint to the elbow joint) and the forearm (the part from the elbow joint to the wrist joint) is an obtuse angle or a straight angle, and the arm muscles are relaxed at this time, which has the advantage of saving effort.

[0036] Reference Figure 1The electric control system 12 includes a lifting switch, which can be directly set on the handle 9 or on the main frame 2. When the lifting switch is set on the main frame 2, the lifting switch must be within the reach of the fingers of the person holding the handle 9. The positive projection of the handle 9 on the ground is closer to the person holding the handle 9 than the rear wheel 8; when the forearm and upper arm of the person form an obtuse angle or a straight angle, the person can press the upper body force on the handle 9, and apply downward pressure to the main frame 2 at the handle 9. When the supporting module to be hoisted is heavy, the forward tilting tendency of the transfer device with the front wheel 7 as the fulcrum can be suppressed, thereby reducing the local force on the fork frame 6, avoiding the front end of the fork frame 6 from bending and deforming upward, and making the transfer device safer and more reliable when transporting heavy objects.

[0037] The ship ballast water supporting module transfer device proposed in this application has the following technical effects:

[0038] The operator holds the handle 9 to push the transfer device to the supporting module to be transported, uses the sling 5 at the front end of the crane arm 3 to connect the supporting module, and then uses the lifting mechanism 10 to push the crane arm 3 up to make the supporting module leave the ground, and then manually pushes the transfer device to the designated position, uses the lifting mechanism 10 to lower the crane arm 3, and assembles the supporting module to the corresponding position; the whole process of lifting the supporting module is operated by one person, saving labor costs; the moving speed of the transfer device is faster than that of the vehicle, thus saving lifting time; by replacing different slings 5 ​​to lift different supporting modules, the number of times personnel handling and vehicle use is reduced, which greatly reduces safety hazards.

[0039] Example 2

[0040] The present application provides a ship ballast water matching module transfer device, referring to Figure 3 , the following structure is added on the basis of Example 1: a bracket 20 is welded on the internal threaded sleeve 41, and is hinged to the main frame 2 through the bracket 20, a motor 14 is fixed on the bracket 20, and a connecting plate 15 is fixed on the rotating shaft of the motor 14; a bearing 19 is fixed on the second pivot seat 18 hinged to the screw 42 on the hanger 13, and the end of the screw 42 is connected to the second pivot seat 18 through the bearing 19, and the bearing 19 enables the screw 42 to rotate relative to the second pivot seat 18; a slot 421 is provided on the end surface of the screw 42 away from the hanger 13, and the connecting plate 15 is plugged and matched with the slot 421 along the axial direction parallel to the screw 42 to realize the connection between the rotating shaft of the motor 14 and the screw 42; after the rotating shaft of the motor 14 is connected to the screw 42, the two are coaxial.

[0041] The function of the above-mentioned added structure is to control the length of the telescopic rod 4 without disassembling the hinge between the screw 42 and the hanger 13. The control method and principle are as follows: under the action of the bearing 19, the screw 42 can rotate relative to the second pivot seat 18 and the internal threaded sleeve 41, and the motor 14 drives the screw 42 to rotate, so that the screw 42 can move axially along the internal threaded sleeve 41, and under the cooperation of the connecting plate 15 and the slot 421, when the screw 42 and the internal threaded sleeve 41 move relative to each other, the screw 42 and the rotating axis of the motor 14 will not be separated, so that the motor 14 can continuously drive the screw 42 to move along the axis of the internal threaded sleeve 41, that is, the purpose of controlling the length of the telescopic rod 4 is achieved.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
