Description

Technical Field

[0001] The invention belongs to the technical field of engineering machinery and relates to a bottom-introducing, self-lifting assembly and disassembly system and an operation method. Background Art

[0002] Existing systems for installing additional sections at the bottom of standard sections offer two methods for lifting: hoisting and jacking. The hoisting mechanism is driven by a winch wire rope, while the jacking mechanism is driven by a hydraulic cylinder. The hoisting mechanism is connected to the standard section via a pin, requiring multiple pin insertions and removals during the section addition process. The jacking mechanism is connected to the standard section via steps, requiring multiple step changes during the section addition process.

[0003] The invention patent with patent number CN114014177A discloses a device for adding sections to increase the height, a method for adding sections to increase the height, and a crane, but the invention has the following disadvantages: first, the device for adding sections involves a lifting frame and a second telescopic section of a telescopic truss structure, and the structure is complex; second, the process is cumbersome, and adding sections requires completing the connection between standard sections, and also completing the connection process between the second and first telescopic sections, which increases the amount of high-altitude work, increases the risk factor, and the efficiency of adding sections is not high; third, in order to meet the needs of road transportation, the bottom section sleeve of the invention is installed on the chassis frame, and the cross-sectional size of the standard section of the equipment it is applicable to is limited; fourth, since it can only meet the needs of vertical engineering machinery such as tower cranes, there are limitations on the application field.

[0004] The invention patent with patent number CN104724643A discloses a double-cylinder lower jacking system and its jacking construction method, but the patent has the following disadvantages: First, for double-cylinder jacking, one section is added at a time, and the cylinder stroke must meet the requirement of being greater than or equal to the height of a standard section. For larger standard sections, the design and manufacturing costs of the cylinder are high, and the cylinder mass is large, making installation difficult; second, in order to meet the synchronization of the double cylinders, the designed supporting jacking structure (jacking frame) increases the structural complexity; third, there is a pin matching process between the step-changing pin shaft and the step hole.

[0005] Both of the above methods have disadvantages such as complicated operation, poor security and low efficiency. Summary of the Invention

[0006] To address the shortcomings of the existing technology, the present invention proposes a section-adding system that allows standard sections to be added within a limited space through lower introduction, thereby increasing the working height of the equipment.

[0010] Furthermore, when constructing the boom, a reasonable construction angle is preset, and the wire rope luffing mechanism of the frame is used to tilt it to the angle before construction is carried out; to meet the angle, the legs on both sides of the trolley 4-1 are introduced with different lengths and are suitable for the bottom section of the boom.

[0011] Furthermore, the upper sleeve 2 includes a bilaterally symmetrical upper half-sleeve 2-1 and a guide pulley 2-2; the two symmetrical upper half-sleeves 2-1 are connected by bolts to form an upper sleeve frame; the guide pulley 2-2 and the guide member 9 are installed on the upper sleeve frame.

[0012] Furthermore, the lower frame 3 includes a lower half frame 3 - 1 that is symmetrical on both sides, and the guide member 9 is installed on the lower half frame 3 - 1.

[0013] Furthermore, the upper frame 2 and the lower frame 3 can be split into two parts; the center lines of the guide members 9 vertically arranged in the upper frame 2 and the lower frame 3 are on the same axis, and the guide members 9 are guide rollers or guide sliders.

[0014] Furthermore, the pinning device is a hydraulic pinning cylinder or a manual pinning device.

[0016] Step 1: Assemble the upper frame 2, lower frame 3, and introduction system 4 on the ground;

[0017] Step 2: Install the upper frame 2 and the lower frame 3 on the base 6 and convert them into a vertical or angled working state;

[0052] The present invention is described in detail below in conjunction with the technical solutions and accompanying drawings.

[0053] The present invention is achieved through the following technical solutions: a standard section assembly and disassembly system, including a preset standard section 1, an upper sleeve frame 2, a lower sleeve frame 3, an introduction system 4, an introduction platform cable 5, a base 6, a lifting mechanism fixed pulley group 7, a lifting hook 8, a pinning device, and a guide member 9.

[0054] In the initial upright state of the system, a preset standard section 1 is introduced into the upper sleeve 2. When assembling the equipment, the introduced standard section A is first placed on the introduction trolley 4-1 that has been previously pulled to the external introduction platform 4-2 of the introduction system 4, and the introduced standard section A is connected to the introduction trolley 4-1 with a pin. The introduction system 4 is started, and the introduced standard section A is introduced into the designated position inside the lower sleeve 3 through the opening of the lower sleeve 3, and the introduction trolley 4-1 is connected to the base 6 with a pin, so that the introduction trolley 4-1 serves as the base section. Then, the fixed connection of the standard section in the upper sleeve 2 is released, and the lifting mechanism is slowly lowered, driving the lifting hook 8 and the preset standard section 1 to fall, so that the preset standard section 1 is docked with the introduced standard section A, and the two standard sections are connected with a pin using a pin device, and the assembly of the introduced standard section A is completed. The pin device is not limited to a hydraulic pin cylinder, a manual pin device, or other forms of pin devices.

[0055] When it is necessary to continue to add sections and raise the equipment, first lower the lifting hook 8 to the hook hanging position of the bottom introduced standard section A. After the hook is hung with the bottom introduced standard section A, the connection between the bottom introduced standard section A and the base section is released, and the lifting mechanism is started. The introduced standard section A is lifted with the lifting hook 8 to separate it from the base section and drive the upper part to lift upward as a whole. This lifting process is continuous and uninterrupted until the introduced standard section A is lifted to the inside of the upper sleeve 2 at a predetermined height. Then, the connection between the basic section introduction trolley 4-1 and the base 6 is released, and the introduction system 4 is started to pull the introduction trolley 4-1 to the external introduction platform 4-2 of the introduction system 4, and the introduction standard section B is placed on the introduction trolley 4-1 and connected with a pin shaft. The introduction trolley 4-1 is started again to introduce the introduction trolley 4-1 to the predetermined position of the lower sleeve frame 3 through the opening of the lower sleeve frame 3, and the introduction trolley 4-1 is connected with the base 6 with a pin shaft; then the lifting hook 8 is slowly lowered to dock the upper structure with the introduction standard section B, and the two standard sections are connected with a pin shaft using a pin-penetrating device, and the assembly of the introduction standard section B is completed.

[0056] The disassembly process is opposite to the installation process. First, disassemble the bottom introduction standard section B and the pin of the introduction standard section A connected to the bottom introduction standard section B. The hook of the lifting mechanism 8 slowly lifts the introduction standard section A connected to the bottom introduction standard section B to disengage it from the bottom introduction standard section B and lift it to the predetermined position of the upper sleeve 2. Then, release the pin connection between the base section introduction trolley 4-1 and the base 6, start the introduction system 4, pull the introduction trolley 4-1 to the external introduction platform 4-2 of the introduction system 4, and then release the pin connection between the introduction trolley 4-1 and the introduction standard section B. Continue to start the introduction system 4 to pull the introduction trolley 4-1 to the predetermined position of the lower casing 3, and connect the introduction trolley 4-1 and the base 6 with a pin to serve as the base section; slowly release the lifting hook 8 to make the introduction standard section A inside the upper casing 2 drop to the base section introduction trolley 4-1 inside the lower casing 3, and connect the base section introduction trolley 4-1 and the introduction standard section A with a pin; at this time, the disassembly process of one standard section of the tower body is completed, and the process is repeated for each standard section until the equipment height is lowered and the remaining structural components of the equipment are removed.

[0057] The transfer process is to release the pin connection at the rear of the lower frame 3 after the disassembly process is completed, slowly release the wire rope of the frame luffing mechanism, and tilt the upper frame 2 and the lower frame 3 forward as a whole until the central axis of the frame is horizontal.

[0058] This system can realize the rapid addition and lifting of standard sections of equipment. It uses hooks for connection, has a simple structure and high lifting efficiency, and has a large lifting stroke. It can realize the process of adding sections in one lifting, avoiding the safety hazards caused by multiple step changes. The hooks are eccentrically arranged to offset the unbalanced torque. In addition, the system's sleeve has a large guide distance, which can effectively reduce the pressure of the guide member 9 on the main chord caused by the unbalanced torque. The guide distance refers to the spacing of the guide member 9, and the guide member 9 is not limited to a guide roller or a guide slider. The introduction trolley 4-1 of the system can be used for the introduction of standard sections and can also be used as a foundation section. The system's sleeve is divided into two parts, upper and lower. In order to meet the introduction of standard sections of large-section tower bodies and meet road transportation conditions, the optional two-part sleeve can be split into two parts.

[0059] The sleeve system of the present invention is primarily composed of an upper sleeve 2 and a lower sleeve 3, which are connected by a pin. The upper sleeve 2 includes a bilaterally symmetrical upper half sleeve 2-1 and a guide pulley 2-2; the lower sleeve 3 includes a bilaterally symmetrical lower half sleeve 3-1. The upper sleeve 2 is composed of two symmetrical upper half sleeves 2-1 connected by bolts to form an upper half sleeve frame, after which the guide pulley 2-2, guide member 9, and pinning device are installed. Optionally, these can be pre-installed within the upper half sleeve 2-1 or installed within the upper sleeve frame after installation. The lower half sleeve 3-1 of the lower sleeve 3 is connected to the base 6 via relevant connecting members and pinned. The guide member 9 of the lower sleeve 3 can be pre-installed within the lower half sleeve 3-1 or installed within the lower sleeve frame after installation. After the upper and lower sleeves 2 and 3 are installed, ensure that the center lines of the guide members 9 in each vertical direction are aligned on the same axis to ensure smooth sliding of the standard section within the sleeve system.

[0060] The introduction system 4 of the present invention consists of an introduction trolley 4-1, an introduction platform 4-2, tracks 4-3, an introduction winch 4-4, and a fixed pulley 4-5. These are connected to a base 6 and to the lower casing 3 via an introduction platform cable 5. The tracks are welded to the introduction platform 4-2 and base 6, forming two parallel tracks at the same height after the introduction system 4 is installed. Both ends of the introduction trolley 4-1 are connected to the introduction winch 4-4 and fixed pulley 4-5 via steel wire ropes. When the introduction winch 4-4 is activated, the introduction trolley 4-1, pulled by the introduction winch 4-4, slides on the tracks to introduce the standard section.

[0061] The present invention also proposes a standard section assembly and disassembly operation method, based on the above standard section installation and disassembly system, comprising the following steps:

[0062] Step 1: Assemble the upper frame 2, lower frame 3, and introduction system 4 on the ground;

[0063] Step 2: Install the upper frame 2 and the lower frame 3 on the base 6 and convert them into a vertical or angled working state;

[0064] Step 3: Install the introduction system 4 on the base 6, and connect the upper frame 2, the lower frame 3, and the introduction system 4 through the introduction platform cable 5;

[0065] Step 4: Release the connection between the introduction trolley 4-1 and the chassis 6, start the introduction system 4, and tow the introduction trolley 4-1 to the predetermined position of the introduction platform 4-2;

[0066] Step 5: Hoist the introduction standard section A onto the introduction trolley 4-1, and connect the introduction standard section A and the introduction trolley 4-1 with a pin;

[0067] Step 6: Start the introduction system 4 to pull the introduction trolley 4-1 and the introduction standard section A placed on the introduction trolley 4-1 to the predetermined position in the lower frame 3, and connect the introduction trolley 4-1 and the chassis 6 with a pin shaft;

[0068] Step 7: Slowly release the lifting hook 8 until the pre-installed standard section 1 is completely docked with the introduced standard section A, and then connect the two standard sections using a pinning device to complete the construction of the foundation section and the bottom section;

[0069] Step 8: Continue to slowly release the lifting hook 8 to the hook hooking position at the bottom of the introduced standard section A and hook it;

[0070] Step 9: Release the pin connection between the introduction trolley 4-1 and the bottom introduction standard section A, and lift the lifting hook 8 to lift the bottom introduction standard section A to the predetermined position of the upper sleeve 2;

[0071] Step 10: Release the pin connection between the introduction trolley 4-1 and the base 6, start the introduction system 4, and pull the introduction trolley 4-1 to the predetermined position of the introduction platform 4-2;

[0072] Step 11: Hoist the introduction standard section B onto the introduction trolley 4-1, and connect the introduction standard section B and the introduction trolley 4-1 with a pin shaft;

[0073] Step 12: Start the introduction system 4 to pull the introduction trolley 4-1 and the introduction standard section B placed on the introduction trolley 4-1 to a predetermined position in the lower casing 3, and connect the introduction trolley 4-1 and the base 6 with a pin shaft;

[0074] Step 13: Slowly release the lifting hook 8 until the introduced standard section A is completely docked with the introduced standard section B, and then connect the two standard sections using a pinning device to complete the equipment sectioning process;

[0075] Step 14: Repeat steps 8 to 13 until the structure reaches the required working height and the construction is completed.

[0076] The preset standard section can be converted into a standard section for pre-installing the top section of the boom when constructing a jib crane; the working state at a certain angle is that when constructing the boom, a reasonable construction angle is preset, and the wire rope luffing mechanism of the frame is used to tilt it to the angle before construction is carried out; in order to meet the angle, the introduction trolley 4-1 can be transformed into an introduction trolley with different lengths of legs on both sides to meet the angle and be suitable for the introduction of the bottom section of the boom.

[0077] This system is suitable for both vertically structured engineering equipment and for increasing the boom length of jib cranes by adding sections to the boom. Jib cranes are defined as cranes whose booms can be adjusted by rotating the boom around a hinge point via a luffing system, including but not limited to crawler cranes and rail cranes.
