Description

Technical Field

[0001] The invention relates to the field of cable hoisting construction, in particular to a device which can replace a main anchor reinforced concrete transfer beam of a cable hoisting system. Background Art

[0002] Cable hoisting systems are often used for the hoisting of large structures such as steel arch ribs. During the hoisting process of large structures, main anchors and corresponding reinforced concrete transfer beams must be set up. Since the main anchors and reinforced concrete transfer beams of a single project have large structural dimensions and more concrete, the engineering procedures are relatively complicated. At the same time, it is also a one-time project, which causes a lot of cost and construction period waste to the project construction. In order to solve the high cost and long construction period of the main anchors and reinforced concrete, it is necessary to design this reusable, convenient, fast and low-cost device.

[0003] However, most of the existing technical solutions have the following defects: First, the main anchor and transfer beam of the cable hoisting system are reinforced concrete, and their structural forms are all special; Second, the main anchor and transfer beam of the cable hoisting system have large structural dimensions and deep excavation depth; Third, the steel bar and formwork construction period of the main anchor and transfer beam of the cable hoisting system is long, the concrete volume is large, and the cost is uncontrollable; Fourth, the conventional main anchor and transfer beam are disposable, and after completion, they need to be removed. Therefore, the device of the present invention provides a steel device that can replace the reinforced concrete of the cable hoisting system, and can be reused to solve the above-mentioned problems. Summary of the invention

[0004] The purpose of the present invention is to provide a device which can be reused and can replace the main anchor steel transfer beam of the cable hoisting system, so as to solve the problems of high cost and long construction period mentioned in the above background technology.

The number of N6 processed is 27 pieces, with equal spacing and an arc length of 7.2cm. In order to prevent the arc slide from deforming during processing, a 2cm groove is opened on the edge. At the same time, the arc slide is welded to the N6 steel plate supporting it below to ensure that the welding is firm.

[0010] According to the reusable cable hoisting system main anchor steel conversion device of the present invention, it is characterized by using rock anchor cables to fix it on the steel beam replacement I-beam, and then using stiffening steel plates and steel pads to strengthen and fix it.

[0011] According to the reusable cable hoisting system main anchor steel conversion device described in the present invention, it is characterized in that the force applied to the two I56 I-beams depends on the weight of the hoisting structure. The weight is about 1000 Nm, and the I-beam used is about 2000 Nm.

[0012] According to the present invention, a reusable cable hoisting system main anchor steel conversion device is characterized in that the steel conversion beam is transmitted to the slide chute through a force-bearing system, and the slide chute needs to be reinforced to meet the force-bearing structure. The reinforcement method uses steel plates to strengthen it to meet the force-bearing structure requirements.

It has the largest number, 27 pieces, and the equidistant arc length is 7.2cm. It is spot welded with the slide steel pipe N7 at the top, and welded with N4 and N5 at the bottom.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: a reusable cable hoisting system main anchor steel conversion device of the present application mainly solves the problem of reusable conversion devices subjected to large forces, the main rope, main lifting rope, main traction rope and other steel ropes of the cable system are fixed through the slide groove of the steel conversion device, and the rock anchor cable is fixed by opening holes on both sides of the I-beam and then using anchors. When subjected to large forces, it is necessary to add stiffening steel plates to fix the rock anchor cable, and it is also necessary to add stiffening steel plates under the steel rope slide groove to ensure its stress state; it greatly shortens the construction cycle time of the cable hoisting system, greatly saves the construction cost of the main anchor and conversion beam, and the steel conversion beam can be reused.

[0023] The reusable cable hoisting system main anchor steel conversion device described in the present application includes: Two I56 I-beams (2.5 meters long, N1) are doubled together, holes are opened at the rock anchor position, and 2 cm steel plates (N2) are used for reinforcement on both sides. 2 cm steel plates (N2) are also used for reinforcement on both sides of the I-beam conversion position.

[0024] Anchor plate (N3), because the flange of the I-beam is thin, after the hole is opened, the single-cable rock anchor is subjected to greater force. In order to ensure its safety and firmness, it is necessary to add an anchor plate at the lock position. The anchor plate is made of 3cm steel plate.

[0025] The chute (N7), the entire cable hoisting system, the main rope, the main lifting, the main traction are mainly for the steel rope, so in the process of processing the chute, A76*6 steel pipe is used, the processing plant is round, and only half of it is taken, such as Figure 4 As shown in: The bottom of the slide is grooved with 2cm steel plate (N6). The number of N6 processed is 27 pieces, the spacing is equidistant, and the arc length is 7.2cm, as shown below Figure 5 As shown in: The rest are the reinforcing steel plates between the slideway and the I-beam. The size and dimensions of these reinforcing steel plates are processed according to actual requirements and design drawings.

[0026] This application solves the problem of high one-time investment in a conversion device for the conventional concrete main anchor and reinforced concrete transfer beam of the cable hoisting system. The steel transfer beam is combined with the rock anchor structure. Two cable rock anchors are connected to a steel transfer beam, and then the main rope, main traction and main lifting of the cable hoisting system are constructed on the corresponding steel transfer beam. The steel transfer beam of this process can be reused many times, which is better than the current conventional main anchor reinforced concrete transfer beam.

I-beam: 2.5 meters in length, 2 I-beams are mainly assembled. This I-beam plays a connecting role in the construction process of the transfer beam. The I-beam is connected to the two cable rock anchors, and the main traction / main lifting / main rope is connected to the I-beam. Because this force system is verified, the I-beam also needs to be treated with stiffening plates to strengthen the force of the entire steel transfer beam.

The main rope, main lifting rope, main traction rope and other steel ropes of the cable system are fixed through the chute of the steel conversion device. The rock anchor is fixed by opening holes on both sides of the I-beam and then using anchors. In the case of large forces, it is necessary to add a stiffening steel plate to the rock anchor fixation.
