Description

Technical Field

[0001] The utility model relates to the technical field of hoisting and transportation, in particular to a multi-functional combined gantry crane system. Background Art

[0002] Hoisting equipment refers to the electromechanical equipment used to carry or move heavy objects. Most hoisting equipment starts the vertical or vertical and horizontal working strokes after taking materials, unloads at the destination, then returns to the material-taking location in an empty stroke to complete a working cycle, and then conducts the second hoisting or handling. Generally speaking, when the hoisting equipment is working, taking materials, transporting, and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent.

[0003] Hoisting equipment is widely used in various industries. According to different structures, it can be divided into several categories such as light and small hoisting equipment, elevators, cranes, and overhead monorail systems. Among them, the cranes used for hoisting large equipment mainly include crawler cranes and bridge cranes (including gantry cranes). However, these two types of hoisting equipment require a large working site and are restricted in application in some occasions.

[0004] At present, the single-piece hoisting weight of large rolling mill housings has exceeded 500 tons, and the height has exceeded 16 meters. For the cranes in the workshops where the rolling mills are located, they are too high and heavy, and other hoisting equipment can only be used for hoisting and then sliding into place for installation. The hoisting equipment often adopts the combination of a gantry and a hydraulic lifting device.

[0005] The Chinese invention patent with the authorization announcement number of CN 106517009 B discloses a "hoisting tool for large rolling mill housings and its construction method". The hoisting tool includes a frame-type support frame, a load-bearing crossbeam, and a lifting module. A horizontal load-bearing crossbeam is provided at the top of the frame-type support frame; the lifting module includes a lifting oil cylinder, a sling, and a steel wire rope. A steel cable is used to connect between the lifting oil cylinder and the sling. The sling includes an upper suspension frame, a connecting plate, a rotating frame, and an upper rotating shaft. The lifting hydraulic cylinder of the lifting module is vertically fixed on the load-bearing crossbeam, and a rotating support frame is provided between the rotating frame and the connecting crossbeam. It adopts the process of combining a steel wire rope hydraulic synchronous lifting device and rotation balance, integrating pushing, lifting and lowering, and rotation.

[0006] The Chinese patent application with the publication number CN115924707A discloses "A Hoisting Method for a Large Rolling Mill Housing", which includes: 1) setting up a ground horizontal sliding device and a hydraulic lifting and sliding device; 2) hoisting the drive-side housing onto the ground horizontal sliding device, installing a hoisting fixture and a center-of-gravity adjustment hoisting tool; 3) using the hydraulic lifting and sliding device as the main hoisting means and the workshop overhead crane to cooperate with the tailing, hoisting the drive-side housing above the installation position and rotating it to a vertical state; 4) completing the installation of the drive-side housing; 5) installing the operating-side housing onto the rolling mill base in the same manner as in steps 2) to 4); 6) installing the rolling mill crossbeam. It is applicable to the working conditions where the workshop overhead crane cannot meet the requirements of hoisting capacity and hoisting height. By adopting the method of "ground horizontal sliding + vertical lifting and then aerial sliding + aerial flipping", the horizontal transportation and vertical hoisting and positioning of the rolling mill housing are realized. The hydraulic lifting and sliding device adopted by it consists of an operating-side column, a drive-side column, a main sliding track beam, a main sliding beam, a main sliding hydraulic jacking device, a transverse support beam, a longitudinal support beam and a hydraulic lifting device; two main sliding track beams are arranged in parallel, and both ends of each main sliding track beam are supported by the drive-side column and the operating-side column respectively. The drive-side column is correspondingly arranged on the drive side of the rolling mill, and the operating-side column is correspondingly arranged on the operating side of the rolling mill; main sliding beams are respectively arranged on the tops of the main sliding track beams, and the main sliding beam can move along the main sliding track beam driven by the main sliding hydraulic jacking device; two transverse support beams and two longitudinal support beams are arranged in a cross shape and staggered on the top of the main sliding beam. One set of hydraulic lifting devices is respectively arranged in the middle parts of the two longitudinal support beams, and rigging is arranged at the bottom ends of the steel wire ropes in the hydraulic lifting devices.

[0007] Although the hoisting equipment combining a gantry and a hydraulic lifting device can meet the needs of hoisting the large rolling mill housing, there are problems such as large equipment outer dimensions and difficult transportation. Most of them are fabricated and installed on the construction site. It is very difficult to reuse the hoisting equipment after the rolling mill installation is completed, resulting in low equipment turnover rate and high construction cost. And the size of the hoisting equipment is relatively fixed, and its versatility for different types of rolling mills is poor. Summary of the Invention

[0051] The installation and use method of the multifunctional combined gantry crane system described in the present utility model is as follows:

[0052] 1) Equip the system components according to the hoisting requirements; if the equipment to be hoisted only needs to be vertically lifted, the combined lifting tower is installed on the ground; if the equipment to be hoisted needs to be vertically lifted and horizontally slid, first install the horizontal sliding mechanism, and then install the combined lifting tower on the sliding beam 10 of the horizontal sliding mechanism;

[0053] 2) Assemble the combined lifting tower; determine the height of the column 1 according to the height of the equipment to be hoisted, and determine the number of column modules 101 required for each column 1; connect the column modules 101 with bolts to form 4 columns 1; from bottom to top, install the corresponding longitudinal sectional support structure and transverse sectional support structure for each assembled support section, and ensure the relative position and verticality of the column 1 by adjusting the telescopic amount of each support; after the last support section is assembled, connect the tops of the 4 columns 1 through the longitudinal top connection beam and the transverse top connection beam to form a stable tower structure;

[0054] 3) Install the climbing hydraulic jacking device 2; assemble the lower telescopic locking mechanism 201 and the upper telescopic locking mechanism 203 in advance; during installation, first place the lower telescopic locking mechanism 201 at the bottom of the corresponding climbing channel, and then control the corresponding telescopic hydraulic cylinder to extend so that the claw 201 is stuck in the lowest tooth-shaped limit card slot 103; then install the hydraulic cylinder 202 and the upper telescopic locking mechanism 203 in sequence;

[0055] 4) Install the longitudinal horizontal beam 3, the transverse lifting beam 4 and the lifting tool 7; select the number of transverse lifting beams 4 and the types and quantities of lifting tools 7 according to the needs;

[0056] 5) Before the hoisting starts, the climbing hydraulic jacking device 2 first climbs to the starting hoisting position; if Figures 7a - 7dAs shown in the figure, during climbing, the climbing hydraulic jacking device 2 first extends the claw 2-1 of the lower telescopic locking mechanism 201 to the tooth-shaped limit card slot 103 at the corresponding position to achieve bottom support. Then, the cylinder rod of the hydraulic cylinder 202 extends upward to move the upper telescopic locking mechanism 203 upward to the corresponding column module 101. Then, the upper telescopic locking mechanism 203 extends the claw 2-1 (the arrow in the figure points outward) to the tooth-shaped limit card slot 103 at the corresponding height to achieve top support. After the claw 2-1 of the lower telescopic locking mechanism 201 retracts (the arrow in the figure points inward), the cylinder rod of the hydraulic cylinder 202 retracts to drive the lower telescopic locking mechanism 201 to move upward. After moving in place, the claw 2-1 of the lower telescopic locking mechanism 201 extends to the tooth-shaped limit card slot 103 at the corresponding height to achieve bottom support again. By repeating such actions, the climbing of the climbing hydraulic jacking device 2 is realized. Through the synchronous control of the hydraulic cylinder 202, the longitudinal horizontal beam 3 and the transverse lifting beam 4 are smoothly lifted. The climbing hydraulic jacking device 2 first climbs to the starting hoisting position and then starts hoisting. First, the equipment to be hoisted is connected by the lifting tool 7. Then, the climbing hydraulic jacking device 2 performs the climbing action again until it reaches the hoisting end position.

[0057] 6) When the equipment to be hoisted needs to be horizontally slid, the sliding hydraulic jacking device 12 is used to drive the sliding beam 10 to move along the sliding track 9, and the combined lifting tower installed on the sliding beam 10 drives the vertically hoisted equipment to perform horizontal sliding.

[0058] The multifunctional combined gantry crane system described in the present utility model has a basic structure including a combined lifting tower and a climbing hydraulic jacking device 2. The combined lifting tower is mainly composed of columns 1, longitudinal lifting beams 3, transverse lifting beams 4 and a surrounding enclosure support system. The climbing hydraulic jacking device 2 is mainly composed of a hydraulic cylinder 202, an upper telescopic locking mechanism 203 and a lower telescopic locking mechanism 201. As a functional extension component structure, a horizontal sliding mechanism can also be configured. Its composition is flexible and can adapt to the hoisting of equipment with different height specifications.

[0059] Among the 4 columns 1 of the combined lifting tower, a set of climbing hydraulic jacking devices 2 are installed in each column 1. The column 1 is composed of multiple column modules 101. The structure and size of each column module 101 are the same, and it has good interchangeability. Each column module 101 is provided with a vertical through groove and a tooth-shaped limit card slot 103. Between the upper and lower two-layer column modules 101 in each column 1, they are fixedly connected by high-strength bolts. The climbing hydraulic jacking device 2 is arranged in the column 1, which can effectively save the space occupied by the hoisting components and achieve the purpose of hoisting in the smallest space. The climbing hydraulic jacking device 2 is built in the column 1 of the combined lifting tower, with better guiding performance, not easily affected by external interference, better running reliability, and improving the force structure of the tower.

[0060] The two longitudinal lifting beams 3 can not only connect the columns on both sides of the tower body, but also are the main load-bearing components during hoisting. The two ends of the longitudinal lifting beam 3 are respectively fixedly connected to the top plate in the upper telescopic locking mechanism 203 by bolts.

[0061] The longitudinal support structure and the transverse support structure connect the columns 1 together, which not only helps to improve the stability of the tower body, but also can effectively adjust the spacing and verticality of the columns 1. Except for the longitudinal top connection beam and the transverse top connection beam provided at the top of the column 1, the longitudinal support structure and the transverse support structure are both arranged in sections, and form a three-dimensional enclosure support system through the upper support, the lower support and the inclined support. The lengths of various supports are configured according to the dimensions of each section, and various supports that make up the longitudinal sectional support structure and the transverse sectional support structure are all designed with standardized modules and are connected by flanges and bolts.

[0062] One or more transverse lifting beams 4 can be provided as needed. The transverse lifting beam 4 spans across the longitudinal lifting beam 3, and a lifting tool 7 is equipped on the transverse lifting beam 4 for lifting the load. The length and cross-sectional dimensions of the transverse lifting beam 4 are configured according to actual needs. To achieve modular assembly, various longitudinal lifting beams 3 and transverse lifting beams 4 with different specifications can be prefabricated for selection. The transverse lifting beam 4 can be arranged in a way that its two ends pass through the longitudinal lifting beam 3, or can be arranged in a way that it is cross-supported on the top of the longitudinal lifting beam 3; a lifting tool 7 is provided on the transverse lifting beam 4, and the position of the lifting tool 7 can be adjusted.

[0063] The horizontal sliding mechanism is arranged at the bottom of the multi-functional combined gantry crane system and is used to drive the combined lifting tower and the hoisted equipment to move horizontally as a whole.
