Description

Technical Field

[0001] This utility model relates to the field of crane installation platform technology, and in particular to a crane installation platform for use in confined spaces. Background Technology

[0002] In situations such as marine operations and mining operations, cranes are required. However, due to limitations in the size of the landing point in marine operations and the limitations in the space of the mine, it is difficult to assemble cranes on the work site. Furthermore, using pre-assembled cranes for movement is costly. Therefore, it is necessary to design a crane installation platform for use in confined spaces.

[0003] In Chinese patent literature, patent number CN2024111857036, published on October 22, 2024, entitled "An installation platform and construction method for a tower crane in a confined space," includes a base, displacement rails, and displacement support plates. Displacement rails are respectively provided on both sides of the base, and a gantry frame is slidably connected in the middle of the displacement rails. A hand-cranked hoist is provided in the middle of the top of the gantry frame. Displacement support plates are slidably connected on the displacement rails on both sides of the gantry frame. A bracket is provided at the left end of the displacement support plate, and a U-shaped support plate is rotatably connected between the two brackets. A limit frame is provided on the left side of the U-shaped support plate.

[0004] The shortcomings of the existing technology are that the crane needs to be assembled in the height direction, but the above solution lacks limiting and positioning in the height direction, and occupies a lot of space in the lateral direction, which is not conducive to the assembly of the crane in a narrow space. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a crane installation platform for confined spaces, which can assist in the assembly of cranes and has high efficiency in utilizing vertical space.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] A crane installation platform for confined spaces is provided for installing the base and bottom section of a crane. The crane installation platform includes a gantry frame, a first slide rail assembly, and a second slide rail assembly. The first slide rail assembly is slidably fitted with a first sliding carriage that carries the crane base, and the second slide rail assembly is fitted with a second sliding carriage that carries the bottom section of the crane. The gantry frame is provided with a lifting assembly that can lift the second sliding carriage. At least one section of the second slide rail assembly is raised above the first slide rail assembly to complete the installation of the base and bottom section.

[0008] The lifting assembly lifts and pulls the second sliding trolley. The base is installed on the first sliding trolley, and the bottom section is installed on the second sliding trolley. The first sliding trolley slides along the first slide rail group, and the second sliding trolley slides along the second slide rail group under the traction of the lifting assembly. This allows the base and bottom section to be longitudinally aligned for installation. The length of the first and second slide rail groups does not occupy a large amount of lateral space, and the installation platform has a high utilization rate of vertical space, making it suitable for crane installation in confined spaces. The positions of the base and bottom section are fixed, facilitating assembly.

[0009] Preferably, the second sliding carriage includes pulleys and a chassis. The chassis includes a left half and a right half, which together form limiting holes on the sides of the corresponding bottom section. The chassis adopts a split structure, and when the left and right halves are disassembled, the bottom section can be disengaged from the limiting holes, making it easy to separate the bottom section from the second sliding carriage and complete the reliable assembly of the bottom section.

[0010] Preferably, the first slide rail assembly includes two sets of parallel first unit slide rails, with several parallel first connecting rods connected to the bottom of the two first unit slide rails. The two sets of first unit slide rails cooperate to realize the erection of the first trolley, and the first connecting rods strengthen the first slide rail assembly and improve the structural reliability of the first slide rail assembly.

[0011] Preferably, the first unit slide rail has a "C" shaped structure, with the openings of the two first unit slide rails facing each other. At least one end of the first unit slide rail is unobstructed so that the first trolley can slide out of the first slide rail assembly. The first trolley can slide out of the first slide rail assembly, which facilitates the loading of the base and the overall unloading of the completed base and bottom section.

[0012] Preferably, the second slide rail assembly includes two parallel second unit slide rails, each with a "C"-shaped structure. One end of the second slide rail assembly is positioned parallel to and above the first slide rail assembly, allowing the second trolley to slide out from this end. The second slide rail assembly guides the second trolley to a suitable height, after which a lifting mechanism can be used to lift the second trolley to complete the installation of the base and bottom section. Both loading and unloading of the second trolley can be accomplished through the lifting mechanism, resulting in high installation efficiency for the bottom section and base.

[0013] Preferably, the second unit slide rail includes a connecting section connected to the first unit slide rail, a transition section inclined to connect the connecting section, and a mounting section inclined to connect the transition section, with the connecting section, transition section, and mounting section smoothly transitioning. The inclined setting of the transition section enables the second trolley to be raised from the connecting section to the mounting section.

[0014] Preferably, several parallel second connecting rods are provided between the two second unit slide rails. This improves the overall structural strength of the second slide rail assembly.

[0015] Preferably, a connecting corner plate is provided between the transition section and the connecting section to improve the structural strength between them.

[0016] Preferably, the lifting assembly includes a mounting rod fixed to the gantry and several hand-cranked hoists mounted on the mounting rod. The hand-cranked hoists are used to traction and lift the second trolley. Attached Figure Description

[0025] One embodiment of this utility model discloses a crane installation platform for confined spaces, used for installing a crane base 1 and bottom section 2. The crane installation platform includes a gantry frame 3, a first slide rail group 6, and a second slide rail group 13. The first slide rail group 6 is slidably fitted with a first sliding carriage 10 that carries the crane base 1, and the second slide rail group 13 is fitted with a second sliding carriage 25 that carries the crane bottom section 2. The gantry frame 3 is provided with a lifting component that can lift the second sliding carriage 25. At least one section of the second slide rail group 13 rises above the first slide rail group 6 to complete the installation of the base 1 and bottom section 2.

[0026] The crane consists of a multi-beam, multi-section boom, with the base 1 and bottom section 2 being the base portion of the crane. Once the base portion is assembled, the other parts can be assembled relatively smoothly.

[0027] The first slide rail group 6 includes two sets of parallel first unit slide rails 8, and several parallel first connecting rods 9 are connected to the bottom of the two first unit slide rails 8. The structure of the first unit slide rail 8 is a "C" shaped slide rail, and the openings of the two first unit slide rails 8 are arranged opposite each other. Both ends of the first unit slide rail 8 are unobstructed, and the first trolley 10 can slide out from both ends of the first slide rail group 6.

[0028] The second slide rail assembly 13 includes two parallel second unit slide rails 18. The second unit slide rails 18 have a "C"-shaped structure. One end of the second slide rail assembly 13 is parallel to and above the first slide rail assembly 6, and the second trolley 25 can slide out of the second slide rail assembly 13 from this end. Specifically, the second unit slide rail 18 includes a connecting section 19 connected to the first unit slide rail 8, a transition section 20 inclined to connect the connecting section 19, and a mounting section 21 inclined to connect the transition section 20. The connecting section 19, transition section 20, and mounting section 21 are smoothly connected. The mounting section 21 is parallel to and above the first slide rail assembly 6, and the second trolley 25 can slide out of the second slide rail assembly 13 from the mounting section 21. Several parallel second connecting rods 22 are provided between the two second unit slide rails 18. A connecting angle plate 23 is provided between the transition section 20 and the connecting section 19, thereby strengthening the structure of the second slide rail assembly 13.

[0029] In the above scheme, the crane mounting platform also includes a first truss 7 and a second truss 14. The first truss 7 is arranged in a straight line, and the first slide rail assembly 6 and the second truss 14 are fixedly installed on the first truss 7. The second truss 14 includes a first horizontal section 15 that is fitted and fixed to the first truss 7, an inclined section 16 that is inclined and fixed in the middle of the first horizontal section 15, and a second horizontal section 17 that is fixed at the outer end of the inclined section 16 and arranged parallel to the first horizontal section 15. In the second unit slide rail 18, the connecting section 19 is located in the first horizontal section 15, the transition section 20 is located in the inclined section 16, and the mounting section 21 is located in the second horizontal section 17. The connecting angle plate 23 is located between the first horizontal section 15 and the inclined section 16. A reinforcing angle plate 24 is fixedly connected between the connecting angle plate 23 and the second horizontal section 17.

[0030] The first sliding carriage 10 includes a carriage 11, with several wheels 12 on both sides of the carriage 11. The wheels 12 extend into the first unit slide rail 8 and roll. The carriage 11 is provided with a fixing structure or recessed positioning groove that cooperates with the base 1.

[0031] The second sliding trolley 25 includes pulleys 26 and a chassis 27. The chassis 27 includes a left half chassis 28 and a right half chassis 29, which together form limiting holes on the sides of the corresponding bottom section 2. There are four pulleys 26, arranged in two groups and rotating on two parallel axes. The left half chassis 28 has two pulleys 26, and the right half chassis 29 has two pulleys 26. The lifting assembly includes a mounting rod 4 fixed to the gantry frame 3 and several hand-cranked hoists 5 slidably mounted on the mounting rod 4. The mounting rod 4 is parallel to the first unit slide rail 8. The left half chassis 28 and the right half chassis 29 of the second sliding trolley 25 each have two protruding hanging ears 30, with hanging rings 31 on the hanging ears 30 to engage with the hand-cranked hoists 5. Once all four hanging rings 31 on the chassis 27 are engaged with the hand-cranked hoists 5, the trolley can be smoothly lifted.

[0032] In use, the first sliding carriage 10 is fitted with a base 1, and the second sliding carriage 25 is fitted with a bottom section 2. Then, the first sliding carriage 10 slides in conjunction with the first slide rail assembly 6, and the second sliding carriage 25 slides in conjunction with the second slide rail assembly 13. The second sliding carriage 25 sequentially passes through the connecting section 19, the transition section 20, and the installation section 21. When the second sliding carriage 25 is in conjunction with the second slide rail assembly 13, a hand-cranked hoist 5 is attached to the hanging rings 31 on the four hanging ears 30. To ensure the stability of the second sliding carriage 25 sliding in the transition section 20, a bottom section 2 can be installed. The bottom section 2 is lifted by a hand-cranked hoist 5 to prevent it from tilting. The hand-cranked hoist 5 pulls the second sliding carriage 25. When the second sliding carriage 25 moves to the installation section 21, the lower end of the bottom section 2 is higher than the upper end of the base 1, and the two cannot be assembled yet. Straighten the hand-cranked hoist 5 connected to the four lugs 30 to separate the second sliding carriage 25 from the second slide rail assembly 13. Smoothly push the second sliding carriage 25 out of the second slide rail assembly 13, and slowly lower the hand-cranked hoist 5 so that the bottom section 2 and the base 1 are aligned. At this point, the assembly of the bottom section 2 and the base 1 is completed. The second slide rail assembly 13 reliably guides and corrects the height and position of the bottom section 2, facilitating the assembly of the bottom section 2 and the base 1 in confined spaces.
