Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a monorail crane track beam fixing device and a monorail crane track beam lifting system. Background Art

[0002] A monorail crane is a type of lifting equipment that uses a special I-beam as a track that is suspended from the bottom of a structural platform beam and runs along the track. It is very common in industrial buildings. The greatest difficulty in the installation and construction of a monorail crane is the installation of the monorail crane track beam, especially the installation of the monorail crane track beam inside a concrete frame structure. Conventional lifting and hoisting methods cannot be used, and the installation position is located at the bottom of the frame beam, which is relatively high. Only unconventional lifting and hoisting measures can be used to lift the track beam to the installation position.

[0003] Common installation methods for monorail hanging track beams generally involve drilling a hole in the platform plate above the track beam, setting up a tripod or other bracket, and attaching a fall chain as a measure to lift the track beam. This solution requires drilling a hole in the structure and has the following disadvantages:

[0004] First, it affects the structural strength.

[0005] Secondly, sealing the holes after opening will affect the subsequent waterproofing requirements of parts such as the roof, leaving quality risks.

[0006] Third, there are many problems such as the inability to use this solution for structural layers that cannot be perforated.

[0007] In the case that the concrete platform does not have holes, are there other measures that can be used as a lifting measure for the monorail crane beam? For this reason, a lifting measure for the monorail crane beam without holes in the concrete platform plate is urgently needed. Summary of the Invention

[0008] Due to the above-mentioned defects in the prior art, the utility model provides a monorail crane track beam fixing device and a monorail crane track beam lifting system to solve the problem that the existing monorail crane track beam is installed on the structure with openings affecting the structural strength and waterproofing.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] A monorail hanging track beam fixing device includes a monorail hanging device; the hanging device includes a hanging base and a reinforcing rib plate arranged on the hanging base; a hanging plate is fixedly arranged obliquely on the reinforcing rib plate, and the outer hanging end extends out of the edge of the hanging base; a through hole is provided at the outer hanging end of the hanging plate for installing a fall chain hanging point.

[0011] The hanging base is an L-shaped main body, and the reinforcing rib plate is an oblique brace arranged at the inner corner of the hanging base.

[0012] A vertical support is fixedly arranged between the edge of the hanging plate base and the hanging plate.

[0013] The hanging plate and vertical support are both 10# channel steel.

[0014] The hanging base and the reinforcing rib plate, the reinforcing rib plate and the hanging plate, and the vertical support and the hanging plate and the hanging base are all connected by welding.

[0015] The included angle between the hanging plate and the hanging base is 60°-70°.

[0016] A track beam mounting through hole is provided at the lower end of the hanging base.

[0017] A monorail crane track beam lifting system includes several monorail crane track beam fixing devices, which are installed at the same horizontal height on the beams and columns of a building, and the lower part of the monorail crane track beam fixing device is suspended and installed with a transport equipment track.

[0018] The upper end of the hanging plate is close to the top plate of the building.

[0019] Lifting lugs are welded to the upper flange of the on-track lifting beam.

[0020] Compared with the prior art, the above invention has the following advantages or beneficial effects:

[0021] 1. It avoids the impact on structural strength caused by opening holes in the roof (floor) during the installation of the monorail hanging track beam.

DETAILED DESCRIPTION

[0028] The structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0032] The hanging base 5 is an L-shaped main body, and the reinforcing rib 6 is an oblique brace set at the inner corner of the hanging base.

[0033] A vertical support 8 is fixedly provided between the edge of the hanging plate base 5 and the hanging plate.

[0034] The hanging plate 7 and the vertical support 8 are both 10# channel steel.

[0035] The hanging base 5 and the reinforcing rib plate 6, the reinforcing rib plate 6 and the hanging plate 7, and the vertical support 8 and the hanging plate 7 and the hanging base 5 are all connected by welding.

[0036] The included angle between the hanging plate 7 and the hanging base 5 is 60°-70°.

[0037] A track beam mounting through hole is provided at the lower end of the hanging base 5 .

[0038] A monorail crane track beam lifting system includes several monorail crane track beam fixing devices, which are installed at the same horizontal height on the beams and columns of a building, and the lower part of the monorail crane track beam fixing device is suspended and installed with a transport equipment track.

[0039] Specific embodiment 2, as Figure 2 As shown,

[0040] A monorail crane track beam lifting system includes several monorail crane track beam fixing devices. This embodiment includes a first monorail crane track beam fixing device 1 and a third monorail crane track beam fixing device 3 arranged on the two end beams, and two second monorail crane track beam fixing devices 2 arranged on both sides of the middle beam. The first monorail crane track beam fixing device 1, the second monorail crane track beam fixing device 2, and the third monorail crane track beam fixing device 3 are installed at the same horizontal height on the beams and columns of the building, and the lower part of the monorail crane track beam fixing device is suspended and installed with a transportation equipment track 4.

[0041] The upper end of the hanging plate is close to the top plate of the building.

[0042] Lifting lugs are welded to the upper flange of the on-track lifting beam.

[0043] The following describes the solution using the installation of a monorail hanging beam at a secondary booster pump station in an ironmaking project as an example.

[0044] The monorail crane track of the secondary booster pump station in this project is located at the bottom of the roof beam. The roof waterproofing has been completed during installation. Opening a hole in the roof for lifting measures requires destroying the roof waterproofing. Subsequent repairs are difficult and the potential risk of roof leakage is too great. Therefore, it is necessary to consider a lifting method that does not require opening a hole in the roof to facilitate the installation of the monorail crane beam. According to the structural design drawings of the secondary booster pump station and the materials such as the track of the suspension transportation equipment, the following information can be obtained:

[0045] 1. The bottom elevation of the monorail track is 6 meters and the track height is 500mm;

[0046] 2. The roof elevation is 7.5 meters and the floor thickness is 120mm;

[0047] 3. The length from the track beam hanging plate bolt to the plate bottom is 450mm;

[0048] According to the above information, it can be concluded that the height of the gap between the top of the track beam and the bottom of the roof is 880mm. In this gap, we weld a 10# channel steel with a hole at the end along the track beam hanging plate reinforcement plate. The angle between the channel steel and the horizontal is controlled at 60°-70°. The top of the channel steel is as close to the roof as possible, and a vertical channel steel is welded at the edge of the hanging plate base as a support for the inclined channel steel. After welding, a fall chain is tied to the hole at the end of the inclined channel steel; in order to avoid gaps between the track and the track beam hanging plate bottom plate during installation, and the loose fit, a lifting measure is made at each node position according to the above method, which can not only ensure easy installation, but also reduce the load borne by a single lifting measure, and improve the structural safety factor of the lifting measure.

[0049] The operating steps for construction using this device are as follows:

[0050] Step 1: Set up the monorail hanging plate installation platform according to the normal process and install the hanging plate.

[0051] Step 2: Measure the gap between the bottom plate of the hanging board and the roof, and cut the oblique channel steel.

[0052] Step 3: Install the inclined channel steel, and control the installation angle between 60-70 degrees.

[0053] Step 4: Measure the size of the plumb line of the diagonal brace and the edge of the hanging plate bottom plate, and cut the material.

[0054] Step 5: Install the vertical support of the inclined channel steel.

[0055] Step 6. After the inclined channel steel and vertical support are firmly installed and welded, hang the fall chain. The specifications of the fall chain should be reasonably selected according to the dead weight of the monorail crane track beam and the number of lifting measures.

[0056] Step 7: Install the improvement measures at each node according to the above method.

[0057] Step 8: Weld the lifting lugs on the flange of the track beam and prepare for lifting.
