Description

Technical Field

[0001] This invention relates to the field of gantry girder construction technology, specifically to a structure and method for installing gantry girder. Background Technology

[0002] Currently, most industrial plants are designed with gantry beams installed on the roof to meet production process requirements, and the lower floor slabs are reserved with hoisting openings for equipment. However, the existence of these openings leads to two problems when using conventional roof-mounted chain hoists for vertical hoisting of gantry beams: (1) Due to the existence of the openings, the gantry beams to be installed cannot be positioned directly below the installation location; (2) Due to the existence of the openings, there is no safe and reliable operating platform above the openings.

[0003] Therefore, there is an urgent need for a structure and method for installing gantry beams to solve the problem that the conventional method of vertically hoisting gantry beams using chain hoists on the roof is inconvenient for installing gantry beams at openings. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a structure and method for installing gantry beams, thereby solving the problem that the conventional method of vertically hoisting gantry beams using chain hoists on the roof is inconvenient for installing gantry beams at openings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structure for installing a gantry beam is characterized by comprising several openings supporting channel steel rails, a forklift mechanism, a horizontal towing mechanism, and a vertical hoisting mechanism. The forklift mechanism includes a forklift and a flatbed truck. The upper ends of the two forks of the forklift are each provided with channel steel rails arranged along the fork direction. The lower end of the flatbed truck is slidably disposed in the channel steel rails, and the upper end of the flatbed truck is used to place the gantry beam to be installed. The several openings supporting channel steel rails are installed parallel to each other above the reserved openings. The spacing between at least two of the openings supporting channel steel rails is consistent with the spacing between the channel steel rails on the two forks. The forklift mechanism is placed on one side of the openings supporting channel steel rails to connect the channel steel rails with the corresponding openings supporting channel steel rails. The other side of the openings supporting channel steel rails is provided with a horizontal towing mechanism for towing the flatbed truck along the channel steel rails and the openings supporting channel steel rails. The vertical hoisting mechanism is installed on the roof for hoisting the gantry beam to be installed below.

[0007] To optimize the above technical solution, the specific measures also include:

[0008] Furthermore, the flatbed vehicle is equipped with two fixing baffles located on both sides of the gantry beam to be installed, which are used to limit the gantry beam to be installed.

[0009] Furthermore, a stiffening rib is provided between the fixed baffle and the flatbed vehicle.

[0010] Furthermore, the forklift is a manually operated forklift with adjustable height.

[0011] Furthermore, the several of the aforementioned opening support channel steel rails are connected and fixed together by connecting steel pipes.

[0012] Furthermore, the horizontal dragging mechanism includes two electric horizontal chain hoists, which are disposed on the side of the channel steel rail supporting the opening, and are respectively used to hook onto both ends of the gantry beam to be installed and drag the gantry beam to be installed and the flatbed vehicle along the channel steel rail and the channel steel rail supporting the opening.

[0013] Furthermore, the vertical hoisting mechanism includes two sets of electric vertical chain hoists and a gantry frame. The electric vertical chain hoists of each set are installed on the roof via the gantry frame. The chain of each set of electric vertical chain hoists passes through the roof and hangs down below, used to hook the two ends of the gantry beam to be installed.

[0014] Furthermore, it also includes a lifting vehicle and at least two lifting vehicle channel steel rails. Several of the opening support channel steel rails are arranged longitudinally and parallel to each other on the reserved opening. At least two of the lifting vehicle channel steel rails are transversely connected to the several opening support channel steel rails in parallel with each other. The rail grooves between the lifting vehicle channel steel rails and the opening support channel steel rails are interconnected. The lifting vehicle is slidably mounted on the lifting vehicle channel steel rails.

[0015] Furthermore, a method of using the gantry beam installation structure as described above includes the following steps:

[0016] Several opening support channel steel rails are fixed above the reserved openings. The opening support channel steel rails are used to protect the reserved openings directly below the gantry beam installation location, while also allowing the flatbed truck to carry the gantry beam to be installed to the designated installation location.

[0017] Drive the forklift to carry the flatbed cart that slides on it and the gantry beam to be installed on the flatbed cart to the side of the support channel steel rail at the opening, and connect the channel steel rails on the two forks of the forklift to the corresponding support channel steel rails of the same width at the opening.

[0018] The flatbed truck and the gantry beam to be installed are moved along the gantry beam and the gantry beam to be installed to the designated installation position using the horizontal towing mechanism located on the other side of the support channel steel rail at the opening. Then, the gantry beam to be installed below is hoisted to the designated height using the vertical hoisting mechanism installed on the roof, and then the subsequent assembly can be carried out.

[0019] Furthermore, a method of using the gantry beam installation structure as described above includes the following steps:

[0020] When the gantry beam to be installed is hoisted to the designated height, the drive lift is moved along the lift's channel steel track to the designated position, and the installation personnel install and secure the gantry beam on the lift.

[0021] The beneficial effects of this invention are:

[0022] This invention utilizes several parallel channel steel rails installed above pre-reserved openings. These rails serve both as installation protection for the openings and, with at least two of them spaced equidistant from the channel steel rails on the forks, as a sliding structure for a flatbed truck to move the gantry beam to be installed along the channel steel rails and the opening support rails to the designated installation location. The coordinated arrangement of the forklift, channel steel rails, and flatbed truck facilitates the movement of the gantry beam to be installed. Simultaneously, the opening support rails facilitate the movement of the gantry beam along the channel steel rails and the opening support rails to the designated installation location. A horizontal towing mechanism drives the movement of the gantry beam along the channel steel rails and the opening support rails, while a vertical hoisting mechanism lifts the gantry beam, thus completing the convenient movement and installation. This effectively solves the problem that conventional methods of vertically hoisting gantry beams using chain hoists on the roof are inconvenient for installing gantry beams at opening locations.

[0023] This invention, on the one hand, uses a combination of forklifts, channel steel rails, and flatbed trucks to form a mobile pulley platform, facilitating the movement of the flatbed truck carrying the gantry beam to be installed; on the other hand, it uses an opening made of I-beams to support the channel steel rails and seat the opening platform, facilitating protection and guiding the gantry beam to be installed below the installation position. Simultaneously, it coordinates with a lifting vehicle channel steel rail connected to the opening support channel steel rails, using the lifting vehicle running within the lifting vehicle channel steel rails to form a mobile operating platform, facilitating subsequent assembly operations by installation personnel.

Detailed Implementation

[0032] The invention will now be described in further detail with reference to the accompanying drawings.

[0033] As attached Figure 1 and attached Figure 7 As shown, an embodiment of the present invention provides a structure for installing a gantry beam, including several openings supporting channel steel rails 7, a forklift mechanism, a horizontal towing mechanism, and a vertical lifting mechanism. The forklift mechanism includes a forklift 10 and a flatbed trolley 9. The upper ends of the two forks of the forklift 10 are each provided with channel steel rails 8 arranged along the fork direction. The lower end of the flatbed trolley 9 is slidably disposed within the channel steel rails 8, and the upper end of the flatbed trolley 9 is used to place the gantry beam 11 to be installed. The several openings supporting channel steel rails 7 are installed parallel to each other above the reserved openings 13. At least two of the opening support channel steel rails 7 have a spacing that is consistent with the spacing of the two forklift channel steel rails 8. The forklift mechanism is placed on one side of the opening support channel steel rail 7 to connect the channel steel rail 8 with the corresponding opening support channel steel rail 7. The other side of the opening support channel steel rail 7 is provided with a horizontal towing mechanism for dragging the flatbed trolley 9 along the channel steel rail 8 and the opening support channel steel rail 7. The vertical hoisting mechanism is installed on the roof to hoist the gantry beam 11 to be installed below.

[0034] This invention utilizes several parallel channel steel rails 7 installed above the reserved opening 13. These rails serve both as installation protection for the reserved opening 13 and as a sliding structure for the flatbed trolley 9 to move the gantry beam 11 to be installed along the channel steel rails 8 and the opening support rails 7, with at least two of them spaced equidistant from the channel steel rails 8 on the two forks. The coordinated arrangement of the forklift 10, channel steel rails 8, and flatbed trolley 9 facilitates the movement of the gantry beam 11 to be installed. Simultaneously, it is equipped with… The installation of the channel steel rail 7 at the opening facilitates the movement of the truss beam 11 to be installed along the channel steel rail 8 and the opening support channel steel rail 7 on the flatbed trolley 9 to the designated installation location. The movement of the truss beam 11 along the channel steel rail 8 and the opening support channel steel rail 7 is driven by a horizontal towing mechanism, and the truss beam 11 is hoisted by a vertical lifting mechanism, thus completing the convenient movement and installation. In this way, the problem of the conventional method of vertically hoisting the truss beam by setting a chain hoist on the roof, which is not convenient for installing the truss beam at the opening location, is effectively solved.

[0035] In this scheme, the forklift mechanism can be equipped with several as needed. Among the several opening support channel steel rails 7, there are corresponding groups of opening support channel steel rails 7 with the same spacing as the channel steel rails 8. The two opening support channel steel rails 7 in each group are used to correspond to the two channel steel rails 8 on one forklift mechanism. Among them, the channel steel rails 8 can be set to allow the flatbed truck 9 to pass through the opening support channel steel rail 7 side only.

[0036] In this scheme, the channel steel rail 7 supporting the opening can be made of I-beams.

[0037] As attached Figure 2 As shown, in one specific embodiment based on the above, the flatbed trolley 9 is provided with two fixing baffles 5 located on both sides of the gantry beam 11 to be installed, which are used to limit the gantry beam 11 to be installed. In this way, the fixing baffles 5 are used to lock and limit the two sides of the gantry beam 11 to be installed on the flatbed trolley 9, thereby avoiding the risk of slippage of the gantry beam 11 to be installed.

[0038] In a further specific embodiment based on the above, a stiffening rib is provided between the fixed baffle 5 and the flatbed trolley 9. This ensures the stability and reliability of the fixed baffle 5 in supporting and limiting its position.

[0039] In another specific embodiment based on the above, the forklift 10 is a height-adjustable manual forklift. Therefore, the height of the forklift 10 can be adjusted according to the height of the channel steel rail 7 supporting the opening, thereby ensuring the connection between the channel steel rail 8 and the corresponding channel steel rail 7 supporting the opening.

[0040] In another specific embodiment based on the above, the several openings supporting the channel steel rails 7 are connected and fixed together by connecting steel pipes 6. This increases the stability and reliability of the connection structure between the several openings supporting the channel steel rails 7.

[0041] In another specific embodiment based on the above, the horizontal dragging mechanism includes two electric horizontal chain hoists 3, which are arranged on the side of the opening support channel steel rail 7, respectively, and are used to hook onto both ends of the gantry beam 11 to be installed and drag the gantry beam 11 to be installed and the flatbed trolley 9 along the channel steel rail 8 and the opening support channel steel rail 7.

[0042] As attached Figure 3 and attached Figure 5 As shown, in another specific embodiment based on the above, the vertical hoisting mechanism includes two sets of electric vertical chain hoists 2 and a gantry frame 1. Each set of electric vertical chain hoists 2 is installed on the roof through the gantry frame 1. The chain of each set of electric vertical chain hoists 2 passes through the roof and hangs down to hook the two ends of the gantry beam 11 to be installed.

[0043] In another specific embodiment based on the above, it also includes a lifting vehicle 4 and at least two lifting vehicle channel steel rails 12. Several opening support channel steel rails 7 are longitudinally parallel to each other on the reserved opening 13. At least two lifting vehicle channel steel rails 12 are transversely connected to the several opening support channel steel rails 7 in parallel. The rail grooves between the lifting vehicle channel steel rails 12 and the opening support channel steel rails 7 are interconnected. The lifting vehicle 4 is slidably mounted on the lifting vehicle channel steel rails 12. Thus, in use, installation personnel can use the lifting vehicle 4 to perform subsequent assembly work on the gantry beam 11 to be installed, which has been hoisted to a designated height. The lifting vehicle 4 can slide along the lifting vehicle channel steel rails 12 and perform vertical lifting and lowering movements. The interconnected rail grooves between the lifting vehicle channel steel rails 12 and the opening support channel steel rails 7 ensure the smooth movement of the flatbed 9 along the opening support channel steel rails 7 or the lifting vehicle 4 along the lifting vehicle channel steel rails 12.

[0044] As attached Figure 4 As shown, a method of using a gantry beam installation structure as described above includes the following steps:

[0045] Several opening support channel steel rails 7 are fixed above the reserved opening 13, and are welded together with connecting steel pipes 6. The opening support channel steel rails 7 are used to protect the reserved opening 13 directly below the gantry beam installation position, and are also used for the flatbed truck 9 to carry the gantry beam 11 to be installed to the designated installation position.

[0046] Drive the forklift 10 to carry the flatbed 9 that is slidably mounted on it and the gantry beam 11 to be installed on the flatbed 9 to the side of the opening support channel steel rail 7, and connect the channel steel rail 8 on the two forks of the forklift 10 with the corresponding opening support channel steel rail 7 of the same width.

[0047] Using a horizontal towing mechanism located on the other side of the support channel steel rail 7 at the opening, the flatbed trolley 9 and the truss beam 11 to be installed are moved along the channel steel rail 8 and the support channel steel rail 7 at the opening to the designated installation position. That is, two electric horizontal chain hoists 3 are used to pull the truss beam 11 to be installed directly below the roof installation position. Then, the vertical hoisting mechanism installed on the roof is used to lift the truss beam 11 to be installed below to the designated height. That is, the electric vertical chain hoist 2 is used to lift the truss beam 11 to be installed directly below to the installation position below the roof, and then the subsequent assembly can be carried out.

[0048] A method of using the gantry beam installation structure with lifting vehicle 4 as described above further includes the following steps:

[0049] When the gantry beam 11 to be installed is hoisted to the designated height, the drive lift 4 is moved along the lift 4 channel steel rail 12 to the designated position, and the installation personnel install and fasten the gantry beam 11 to be installed on the lift 4.

[0050] One specific embodiment of the present invention is as follows:

[0051] When protecting the reserved opening 13 directly below the installation location of the gantry beam, the following should be noted: Figure 6 The crisscrossing and interconnected opening support channel steel rails 7 and lifting vehicle channel steel rails 12 are fixed above the reserved opening 13. The opening support channel steel rails 7 can be reinforced by welding with connecting steel pipes 6. The opening support channel steel rails 7 are used for the movement of the flatbed trolley 9, and the lifting vehicle channel steel rails 12 are used for the movement of the lifting vehicle 4.

[0052] Drive the forklift 10 to carry the flatbed 9 that is slidably mounted on it and the gantry beam 11 to be installed on the flatbed 9 to the side of the opening support channel steel rail 7, and align the channel steel rail 8 on the two forks of the forklift 10 with the corresponding opening support channel steel rail 7 of the same width, and then adjust and raise the forklift 10 so that the channel steel rail 8 on it is connected to the opening support channel steel rail 7.

[0053] Using the chains of two electric horizontal chain hoists 3 located on the other side of the support channel steel rail 7 at the opening, hook the chains of the two ends of the gantry beam 11 to be installed, and pull the traction flatbed 9 and the gantry beam 11 to be installed on it to the direct below the roof installation position; then using the chains of two electric vertical chain hoists 2 installed on the roof, hook the chains of the gantry beam 11 to be installed to the two ends, and lift the gantry beam 11 directly below to the installation position under the roof; then, drive the lifting vehicle 4 to move along the lifting vehicle channel steel rail 12 to the designated position, and the installers reach the required position on the lifting vehicle 4 to further install and secure the gantry beam 11.

[0054] On the one hand, the present invention forms a mobile pulley platform by combining a forklift 10, a channel steel rail 8, and a flatbed truck 9, which facilitates the movement of the flatbed truck 9 carrying the gantry beam 11 to be installed. On the other hand, the channel steel rail 7, made of I-beams, is used to support the opening platform, which facilitates protection and guides the gantry beam 11 to be installed below the installation position. At the same time, a lifting vehicle channel steel rail 12 connected to the opening support channel steel rail 7 is set up, and the lifting vehicle 4 runs in the lifting vehicle channel steel rail 12 to form a mobile operating platform, which facilitates the subsequent assembly work by the installation personnel.
