Description

Technical Field

[0001] This utility model belongs to the field of monorail crane beam installation technology, and in particular relates to a monorail crane beam installation and positioning device. Background Technology

[0002] After the main construction of industrial plant facilities such as equipment rooms and pump rooms is completed, monorail crane beams are installed inside the plant to facilitate subsequent equipment installation and routine maintenance. Since the monorail crane beams are installed on the main structural concrete beams, current techniques typically involve installing lifting equipment such as chain hoists on the concrete beams after the main structure is completed, or creating pre-reserved openings in the roof and suspending chain hoists for installation. Installing chain hoists on concrete can easily damage the concrete beams, while pre-reserved openings in the roof can affect the later waterproofing effect. Furthermore, both methods require positioning the monorail crane beams in the air, which is not only difficult to operate and has poor positioning accuracy, but also adversely affects construction efficiency and safety. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a monorail crane beam installation and positioning device, which can quickly, efficiently and accurately position the monorail crane beam in the horizontal and vertical directions, ensuring installation accuracy.

[0004] The technical solution adopted by this utility model is: a monorail crane beam installation and positioning device, comprising:

[0005] The support base is located below the concrete beam of the factory building where the monorail crane beam is to be installed.

[0006] A sliding track is slidably mounted on the top of the support base;

[0007] A horizontal moving mechanism is disposed on both sides of the sliding track to drive the sliding track to move horizontally;

[0008] A vertical moving mechanism is located at the top of the sliding track to support and drive the monorail crane beam to move vertically.

[0009] Furthermore, the sliding track is arranged in the same direction as the monorail crane beam; the vertical moving mechanism is aligned with the center line of the monorail crane beam in the design.

[0010] Furthermore, the vertical moving mechanism is evenly arranged along the direction of the sliding track.

[0011] Furthermore, it also includes a retaining seat, which is fixed to the support base and connected to the end of the horizontal moving mechanism away from the sliding track.

[0012] Furthermore, the two ends of the horizontal moving mechanism are respectively hinged to the abutment seat and the sliding track.

[0013] Furthermore, the horizontal moving mechanism includes a first driving member and a first telescopic member, the first telescopic member extending or shortening under the action of the first driving member.

[0014] Furthermore, the vertical moving mechanism includes a second driving member and a second telescopic member, the second telescopic member extending or shortening under the action of the second driving member.

[0015] Furthermore, the support base includes a support frame and a sliding beam, the sliding beam being disposed on the top of the support frame, and the sliding track being slidably connected to the groove of the sliding beam.

[0016] Furthermore, it also includes a hanger, which is installed on the concrete beam of the factory building and is used to connect the positioned monorail crane beam.

[0017] A method for installing and positioning a monorail crane beam, using the aforementioned monorail crane beam installation and positioning device, includes the following steps:

[0018] Fabricate the support frame and sliding beam to form the support base;

[0028] (1) This application can quickly, efficiently and accurately position the monorail crane beam 6 in the horizontal and vertical directions. Compared with using hoisting equipment or chain hoisting devices to lift the monorail crane beam 6 in the air for positioning, it reduces the difficulty of positioning operation, improves positioning efficiency and positioning accuracy, and avoids long-term high-altitude operation, thus improving operation safety.

[0029] (2) This application uses hoisting equipment to place the monorail crane beam on the monorail crane beam installation and positioning device before the factory roof is closed, which avoids the situation that hoisting equipment cannot be used for hoisting operations after the factory roof is closed.

Detailed Implementation

[0034] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0035] like Figures 1-2 As shown in the figure, this utility model embodiment proposes a monorail crane beam installation and positioning device, including a support base 1, a sliding rail 2, a horizontal moving mechanism 3 and a vertical moving mechanism 4. Each part is described in detail below.

[0036] like Figures 1-2 As shown in the embodiments of this application, this application provides a monorail crane beam installation and positioning device, including:

[0037] Support 1 is located below the concrete beam 7 of the factory building where the monorail crane beam 6 is to be installed;

[0038] Sliding track 2 is slidably mounted on top of support base 1;

[0039] The horizontal moving mechanism 3 is arranged on both sides of the sliding track 2 to drive the sliding track 2 to move horizontally;

[0040] The vertical moving mechanism 4 is located on top of the sliding track 2 and is used to support and drive the monorail crane beam 6 to move vertically.

[0041] The support base 1 is set on the factory floor at a predetermined height to provide an installation platform for the sliding rail 2 and the horizontal moving mechanism 3, while also providing support for the monorail crane beam 6. Because the monorail crane beam 6 is quite heavy, taking a medium-sized monorail crane beam 6 as an example, its self-weight can reach 6 to 10 tons. Therefore, the support base 1 in this application has undergone stress calculation during design to ensure that it has sufficient load-bearing capacity and can provide sufficient support for the monorail crane beam 6, the sliding rail 2, the horizontal moving mechanism 3, and the vertical moving mechanism 4, so as to ensure that the overall structure has good stability.

[0042] The aforementioned sliding rail 2 is slidably connected to the support base 1. The top of the support base 1 is provided with a horizontal sliding surface, on which a lubricating medium is added. The sliding rail 2 is placed on this sliding surface. When subjected to the force of the horizontal moving mechanism 3 on either side, the sliding rail 2 can move horizontally on the sliding surface according to the direction of the force, thereby adjusting the horizontal position of the monorail crane beam 6. After the monorail crane beam 6 is horizontally positioned, the sliding rail 2 is subjected to opposite forces from the horizontal moving mechanisms on both sides, which fixes the sliding rail 2 on the sliding surface, making it difficult for it to move. Then, the height of the monorail crane beam 6 can be adjusted by the vertical moving mechanism 4, ultimately achieving the positioning of the monorail crane beam 6 in the height direction.

[0043] The above technical solution enables rapid, efficient, and accurate positioning of the monorail crane beam 6 in both horizontal and vertical directions. Compared to using hoisting equipment or chain hoists to lift the monorail crane beam 6 into the air for positioning, this reduces the operational difficulty of positioning, improves positioning efficiency and accuracy, and avoids prolonged high-altitude operations, thus enhancing operational safety.

[0044] Furthermore, in this embodiment, the sliding track 2 is arranged in the same direction as the monorail crane beam 6, and there are two or more vertical moving mechanisms 4, which are aligned with the center line of the monorail crane beam 6 in the design. When the monorail crane beam 6 is installed on the vertical moving mechanism 4, the vertical moving mechanism 4 is aligned with the center line of the monorail crane beam 6, so that the actual center line of the monorail crane beam 6 is aligned with the center line in the design. The horizontal position of the monorail crane beam 6 can be positioned by adjusting the axial position of the center line through the horizontal moving mechanism 3.

[0045] In the above embodiment, the center line of the monorail crane beam 6 in the design can be measured on the sliding track 2 using a measuring instrument, and a vertical moving mechanism 4 can be set on the center line. Then, the center line of the monorail crane beam 6 is measured and marked at the bottom. When the monorail crane beam 6 is placed on the vertical moving mechanism 4, it is only necessary to align the two vertical moving mechanisms 4 located on both sides with the mark to accurately place the monorail crane beam 6 on the vertical moving mechanism 4, and the actual center line position of the monorail crane beam 6 is aligned with the center line of the monorail crane beam 6 in the design.

[0046] Furthermore, in the above embodiment, the vertical moving mechanism 4 is evenly arranged along the center line of the sliding track 2. This arrangement ensures that the center line of the monorail crane beam 6 placed on the vertical moving mechanism 4 is aligned with the center line of the sliding track 2, and that all parts of the monorail crane beam 6 are evenly supported, thus ensuring that the monorail crane beam 6 and the sliding track 2 are subjected to balanced forces, thereby ensuring the stability of the sliding track 2 during movement.

[0047] Furthermore, in the above embodiments, the monorail crane beam installation and positioning device proposed in this application also includes a retaining seat 5, which is fixed to the support seat 1 and connected to the end of the horizontal moving mechanism 3 away from the sliding track 2. By setting the retaining seat 5, support can be provided for the horizontal moving mechanism 3, preventing it from moving under the reverse force during the movement of the sliding track 2, thus affecting the safety of operation and the accuracy of positioning.

[0048] Furthermore, in the above embodiment, the two ends of the horizontal moving mechanism 3 are hinged to the abutment seat 5 and the sliding track 2, respectively. To ensure that the sliding track 2 is subjected to balanced force and moves stably, the connection position between the horizontal moving mechanism 3 and the sliding track 2 should preferably be at the center line of the sliding track 2, and be able to provide force along the direction of the center line. By means of hinged connection, a certain angular deviation between the horizontal moving mechanism 3 and the sliding track 2 is allowed, and strict alignment is not required. The hinge point can be adaptively adjusted to ensure effective transmission of force, avoiding installation difficulties or structural deformation caused by forced alignment. At the same time, under large load, the hinge point can adaptively adjust the direction of the force to ensure that the horizontal moving mechanism 3 always outputs power along the optimal path, so that the sliding track 2 can move stably.

[0049] In the above embodiment, hinge supports 33 are provided on the side walls opposite to the clamping seat 5 and the sliding track 2. The two ends of the horizontal moving mechanism 3 are respectively connected to the hinge supports 33, which further reduces the process difficulty of connecting the horizontal moving mechanism 3 with the clamping seat 5 and the sliding track 2 and improves the installation efficiency. At the same time, this connection method is convenient to dismantle after the operation is completed, so that the sliding track 2 and the horizontal moving mechanism 3 can be transferred to other working positions for continued use, saving construction costs.

[0050] Further, in the above embodiment, the horizontal moving mechanism 3 includes a first driving member 31 and a first telescopic member 32, the first telescopic member 32 extending or shortening under the action of the first driving member 31. Preferably, the horizontal moving mechanism 3 in this embodiment is a hydraulic jack. It can be understood that during the horizontal positioning of the monorail crane beam 6, the horizontal moving mechanisms 3 located on both sides of the sliding track 2 can cooperate with each other. When the first telescopic member 32 on one side extends, the first telescopic member 32 on the other side shortens synchronously, so that the sliding track 2 is always constrained by the horizontal moving mechanisms 3 on both sides during the movement, and is fixed in the positioning position after positioning is completed.

[0051] Furthermore, in the above embodiment, the vertical moving mechanism 4 includes a second driving member 41 and a second telescopic member 42, which extends or retracts under the action of the second driving member 41. Preferably, the horizontal moving mechanism 3 in this embodiment uses a hydraulic jack, and several vertical moving mechanisms 4 can extend or retract synchronously, so that each part of the monorail crane beam 6 can be lifted synchronously in a horizontal posture to ensure the stability and safety of the operation.

[0052] Furthermore, in the above embodiment, the support base 1 includes a support frame 11 and a sliding beam 12. The sliding beam 12 is disposed on the top of the support frame 11, and the sliding track 2 is slidably connected to the groove of the sliding beam 12. Specifically, the top of the sliding beam 12 is provided with a groove, and the sliding track 2 is disposed in the groove and moves within the groove; the support frame 11 is formed by connecting several columns and beams to form a frame structure. By designing the sliding beam 12 with a groove, it is easier to apply the lubricating medium into the sliding groove, while also restricting the sliding path of the sliding track 2 to prevent it from deviating during sliding, further improving the safety of the operation.

[0053] Furthermore, in the above embodiments, the monorail crane beam installation and positioning device proposed in this application also includes a hanger 8, which is disposed on the concrete beam 7 of the factory building and is used to connect the positioned monorail crane beam 6.

[0054] This application also proposes a method for installing and positioning a monorail crane beam, using the aforementioned monorail crane beam installation and positioning device, including the following steps:

[0055] S1. Fabricate the support frame 11 and the sliding beam 12, and weld them together to form the support base 1;

[0056] In this embodiment, the support frame 11 includes columns and beams, with the beams arranged longitudinally and laterally. Both the columns and beams are made of steel pipes. The sliding beam 12 is made of steel profiles and has sliding grooves. The support base 1 has been tested for stress and can provide sufficient support for the monorail crane beam 6.

[0057] S2. Install the vertical moving mechanism 4 onto the sliding track 2;

[0058] In this embodiment, the number of vertical moving mechanisms 4 is set according to their bearing capacity and the length of the monorail crane beam 6, and they are evenly arranged along the center line of the sliding track 2 during installation.

[0059] S3. Place the sliding track 2 on the upper part of the sliding beam 12;

[0060] In this embodiment, the sliding track 2 is placed in the groove of the sliding beam 12, and the center line of the sliding track 2 is aligned with the center line of the monorail crane beam 6 in the design in the height direction.

[0061] S4. Install the clamping seat 5 at both ends of the sliding beam 12;

[0062] In this embodiment, the abutment seats 5 are symmetrically arranged at both ends of the sliding beam 12; the hinge supports 33 on the abutment seats 5 and the hinge supports 33 on the side wall of the sliding track 2 on the corresponding side are both arranged corresponding to the center line of the sliding track 2.

[0063] S5. Hinge the horizontal moving mechanism 3 to the abutment 5 and the sliding rail 2 respectively;

[0064] S6. Before the factory roof is closed, use hoisting equipment to place the monorail crane beam 6 on the upper part of the vertical moving mechanism 4;

[0065] In this embodiment, a centerline mark is provided at the bottom of the monorail crane beam 6. When placing the monorail crane beam 6 on the vertical moving mechanism 4, it is only necessary to align the two vertical moving mechanisms 4 located on both sides with the mark.

[0066] S7. The horizontal moving mechanism 3 adjusts the horizontal position of the monorail crane beam 6.

[0067] After the monorail crane beam 6 is initially positioned, the deviation between its actual centerline position and the intended installation centerline position is checked using measuring instruments to determine the direction and displacement distance for axial adjustment. Subsequently, two horizontal moving mechanisms 3 are operated synchronously, with one of the mechanisms generating a thrust on the sliding rail 2, slowly pushing the monorail crane beam 6 towards the other mechanism 3. At the same time, the telescopic component of the other mechanism 3 shortens until the monorail crane beam 6 moves to the measured displacement distance. The centerline position of the monorail crane beam 6 is checked again. If the requirements are met, the horizontal positioning of the monorail crane beam 6 is completed; if not, the adjustment is repeated.

[0068] S8. The vertical moving mechanism 4 is used to adjust the height of the monorail crane beam 6.

[0069] After completing the horizontal positioning of the monorail crane beam 6, the bottom height of the monorail crane beam 6 is measured using a measuring instrument, and the height difference between its bottom height and the bottom elevation in the design is calculated. Then, several vertical moving mechanisms 4 on the sliding track 2 are operated synchronously to push the monorail crane beam 6 upward to reach the height difference. The bottom height of the monorail crane beam is checked again. If the requirements are met, the height positioning of the monorail crane beam 6 is completed; if not, the step is repeated for adjustment.

[0070] S9. Install the hanger 8 onto the concrete beam 7 of the factory building and connect and fix it to the monorail crane beam 6.

[0071] Once it is determined that the height of the monorail crane beam 6 meets the requirements, the hanger 8 is installed on the concrete beam 7 of the factory building, and the monorail crane beam 6 is fixed by the hanger 8.

[0072] In other embodiments of this application, the installation of the hanger 8 on the concrete beam 7 of the factory building can be completed first, and then connected to the monorail crane beam 6 after the monorail crane beam 6 is positioned.

[0073] By placing the monorail crane beam on the monorail crane beam installation and positioning device using hoisting equipment before the factory roof is closed, the situation where hoisting equipment cannot be used for hoisting operations after the factory roof is closed is avoided. Compared with the existing technology of hoisting the monorail crane beam after the main structure is completed, this avoids damage to the main structure.
