Description

Technical Field

[0001] This utility model relates to the field of port machinery and equipment technology, and in particular to a heightening device for container equipment in a site. Background Technology

[0002] The shipping industry is developing rapidly, and equipment replacement cycles are becoming shorter and shorter. With a large number of containers and limited space, yards need to be fully utilized, but the height of older container equipment (mainly rail-mounted gantry cranes and rubber-tired gantry cranes) is insufficient. Besides purchasing new equipment, modifying older equipment is unavoidable. Increasing the height of existing equipment is the most common and effective modification method.

[0003] The most common way to raise equipment is to lengthen the section below the lower crossbeam of the crane. This method requires large raising devices, has a long construction period, and is expensive. For example, the raising technology disclosed in Chinese patent "CN202510375721.9, Container Crane Raising Device and Raising Method" involves adding raising blocks above the traveling trolley. The lifting mechanism is complex, increases the height of the lower crossbeam, and reduces safety. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide a site container equipment raising device that has a lower cost and is easy to operate.

[0005] The technical solution adopted by this utility model is:

[0006] A lifting device for a yard container equipment is characterized by comprising a ground base and a lifting base. The lifting base is positioned above the ground base via two lower support columns. Two upper guide columns are provided on the lifting base, with guide holes for the lifting brackets passing through them. A jack is mounted on the lifting base and connected to a hydraulic station. The piston of the jack is located below the lifting bracket. The lifting bracket includes guide holes at both ends. Pin holes of different heights are provided on the upper guide columns. Locking pins inserted into the pin holes fix the position of the lifting bracket's sleeve at a certain height. The lifting bracket extends forward to form a support, and the bracket is used to support the box-shaped door legs of the yard container equipment.

[0007] Furthermore, the front end of the lifting bracket is a polygonal steel plate, with multiple horizontal and vertical stiffeners set on the top front and sides, and the vertical edges of several vertical stiffeners located at the edge of the polygonal plate.

[0008] Furthermore, several lifting blocks are provided on the jack's rod. After the lifting bracket is lifted, it is fixed by a locking pin. After the jack is retracted, lifting blocks are added to the jack's rod.

[0009] Furthermore, the lifting blocks are connected to each other and to the lifting rods via multiple bolts at the connection points.

[0010] Furthermore, the tops of the two upper guide posts are fixedly connected by a link.

[0011] Furthermore, the lower support column is formed by two connected sections. The lower section of the lower support column is fixedly connected to the ground base, and the upper section of the lower support column is connected to the lifting base flange. The upper guide column is formed by two connected sections, and the lower section of the upper support column is fixedly connected to the lifting base flange.

[0034] The specific implementation method of the site container equipment raising device of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Site container equipment includes various types of equipment such as rail-mounted gantry cranes and rubber-tired gantry cranes, which have similar structures. The following description uses a rail-mounted gantry crane as an example to illustrate this utility model.

[0036] See appendix Figure 1 , 2 Below the track-mounted crane 1 are two lower crossbeams 2, with door legs 3 mounted on the lower crossbeams 2, and a traveling trolley 4 located below the lower crossbeams 2. The breakthrough point of this patent for heightening is the connection between the door legs 3 and the lower crossbeams 2, where the height is increased by separation. In addition, the structure of the door legs 3 has a certain taper, so the door legs 3 can be supported by a slot.

[0037] See appendix Figure 3 , 4 The lifting device 21 of the rail-mounted crane 1 includes a ground base 5 and a lifting base 6. The lifting base 6 is mounted above the ground base 5 via two lower support columns 7. The lower support columns 7 are formed by two interlocking sections. The lower section of the lower support column 7 is fixedly connected to the ground base 5, and the upper section of the lower support column 7 is fixedly connected to the lifting base 6. The split structure can not only adapt to the lower crossbeam 2 of the rail-mounted crane 1 at different heights, but also reduce weight and facilitate transportation. Since the ground base 5 is placed on the ground foundation below the traveling trolley 4, and the lifting base 6 is installed above the lower crossbeam 2, the segmented structure is easier to install.

[0038] Two upper guide columns 8 are installed on the lifting base 6. Similarly, each upper guide column 8 is formed by two interlocking sections, with the lower section of the upper guide column 8 fixedly connected to the lifting base 6. The top of the upper guide column 8 is connected by a connecting strip 10 to maintain its stability. Both the ground base 5 and the lifting base 6 use steel structure assemblies, and the upper guide columns 8 and lower support columns 7 are made of steel to withstand the enormous pressure during operation.

[0039] Lifting brackets 9 are fitted onto the two upper guide columns 8. The lifting brackets 9 include sleeve holes 11 at both ends and a connecting plate 12 in the middle. The front side of the connecting plate 12 extends to form a lifting groove 13. The polygonal steel plate 13 has a square notch for fitting and fixing to the box shape of the door leg 3. On the connecting plate 12 on both sides and the rear side of the square notch, multiple horizontal and vertical stiffening plates 14 are provided. The vertical edges of several vertical stiffening plates 14 are located at the edge of the square notch, forming a reinforcing plate at the square notch position. When the square notch is matched with the door leg 3, it increases the strength of the polygonal steel plate 13 and improves the supporting force to lift the door leg 3.

[0040] Vertical plates 23 are installed on both sides below the lifting base 6. The space between the vertical plates 23 is used to cooperate with the lower crossbeam 2, so that the lifting device 21 is more stable after installation.

[0041] The upper guide column 8 is provided with pin holes 15 at different heights, which are used to insert locking pins 16. When the lifting bracket 9 lifts the door leg 3, the locking pins 16 are inserted into the pin holes 15 to fix the position of the sleeve hole 11 of the lifting bracket 9 at the lifting height.

[0042] A jack 17 is installed on the lifting base 6. The jack 17 is connected to the hydraulic station 18. The jack rod of the jack 17 is located below the lifting bracket 9. The jack rod of the jack 17 is used to place and fix the lifting block 19 so that the lifting bracket 9 can be lifted to the predetermined height step by step.

[0043] The lifting block 19 is square, with screw holes on its upper and lower ends for connection with the jack rod of the jack 17 and for connection between adjacent lifting blocks 19, enabling the jack 17 to lift the lifting bracket 9 to a predetermined height. After the jack 17 gradually lifts the lifting bracket 9 to a certain height, the lifting bracket 9 is fixed by the locking pin 16. Then, lifting blocks 19 are added above the jack rod of the jack 17 to gradually increase the height of the lifting bracket 9.

[0044] In the application of the embodiment, each set of lifting device 21 is equipped with a hydraulic station 18 for the jack 17. The lifting capacity of the jack 17 exceeds 100 tons, the stroke of the jack 17 is 250mm, and the pad is 180mm high, which basically meets the lifting operation of the commonly used rail crane 1.

[0045] See appendix Figure 5-7 The process of raising the rail crane 1 using the raising device 21 is as follows:

[0046] First, preparatory work is carried out, including clearing the area around the rail-mounted crane 1 and addressing any auxiliary facilities that may be affected during the lifting process. This includes cutting off the inclined ladder 20 and relocating or cutting off any electrical, piping, or other equipment. This is to mitigate any additional risks that may arise during the lifting process.

[0047] Prepare lifting blocks 19, heightening blocks 22, welding equipment, cutting equipment, hardware tools and other equipment to ensure the smooth completion of the heightening process.

[0048] Then, four lifting devices 21 are installed at the position of the gate leg 3, the ground base 5 is installed on the ground below the traveling trolley 4 of the rail crane 1, and the lifting base 6 is located above the lower crossbeam 2 of the rail crane 1, so that the lifting groove 13 of the lifting bracket 9 cooperates with the gate leg 3. During the installation process, since both the lower support column 7 and the upper support column 8 can be disassembled and assembled, the operation is relatively convenient. The installation process ensures the quality of the tight connection and guarantees its safety.

[0049] After installation, start the hydraulic station 18 to enable the four lifting devices 21 to support the door leg 3 with the lifting slot 13 and maintain this state. The connection between the door leg 3 and the lower crossbeam 2 is removed by cutting. The way the door leg 3 is connected to the lower crossbeam 2 determines the method of removal. In addition to cutting, for door legs 3 connected by fasteners, the bolts are released to separate the door leg 3 from the lower crossbeam 2.

[0050] The jacks 17 of the four lifting devices 21 are driven to lift the brackets 9 and raise the gate legs 3. The four lifting devices 21 must be synchronized so that the four gate legs 3 rise simultaneously. When the gate legs 3 have risen one stroke height, that is, when the jacks 17 can be retracted to the height of a lifting block 19, the jacks 17 are held at this height. A locking pin 16 is inserted into the pin hole 15 at the position of the upper support column 8 of the lifting bracket 9 to fix the lifting bracket 9 at this height.

[0051] The jacks 17 that drive the four lifting devices 21 retract by one stroke height, leaving enough space to insert a lifting block 19. The lifting block 19 is then inserted into the retracted space and secured to the jack rod below or the previously inserted lifting block 19 with fasteners.

[0052] Then, repeatedly drive jack 17 to raise the lifting bracket 9, causing the door leg 3 to rise another stroke. Fix the lifting bracket 9 and insert the lifting block 19. Repeat this process multiple times until the door leg 3 is lifted to the height of the lifting block 22. At this point, insert the lifting block 22 between the door leg 3 and the lower crossbeam 2, and form a support between the door leg 3 and the lower crossbeam 2 by fastening or welding, thus raising the base of the door leg 3.

[0053] After completion, the jack 17 of the lifting device 21 is retracted, and the lifting block 19 is removed, and the entire lifting device 21 is removed in sequence.

[0054] Finally, the relevant auxiliary facilities were repaired and restored, such as reconnecting the missing parts of the inclined ladder 20 and reconnecting the wires, cables and gas pipes.

[0055] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
