Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated subway station engineering, and in particular to intelligent assembly equipment and a construction method for prefabricated components. Background Art

[0002] In recent years, in accordance with national policy requirements, the development of the construction industrialization has been promoted, and the labor-intensive construction model has been transformed into an intensive and mechanized one. It is required to vigorously develop prefabricated buildings and promote green building methods. More and more cities are using prefabricated subway stations in new subways.

[0003] At present, most prefabricated subway stations are assembled by gantry cranes and intelligent trolleys, which have the disadvantages of cumbersome operation, large amount of steel used in equipment, high requirements on foundation flatness, and long single-ring assembly time. With the promotion of prefabricated subway stations, some stations have adopted the assembly method of gantry cranes and simple trolleys, which mainly uses crane-assisted assembly and has a fast construction speed.

[0004] For example, the following prior patent application, application number CN 113200459 A, is entitled "A kind of adjustable force state hoist for installing the roof of a prefabricated subway station and its application". Its hook uses a hydraulic hook that can be controlled independently of each other, and controls the length and opening of the hoist at each lifting point to control the opening amount of the component to realize the assembly of the roof and the side wall, but it is unable to achieve precise control of each lifting point. Application number CN 117699670 A, is entitled "Component gantry crane and its fine-tuning balance control method". Its lifting system uses two fixed wheels. When the jack is lifted, the angle of the lower side of the wire rope will change, and there is friction between the wire rope and the lower fixed wheel. The force detected by the jack sensor is inconsistent with the actual force, which poses certain safety hazards.

[0005] In summary, the existing gantry crane construction and installation has a low level of intelligence, the actual force monitoring of the lifting points is inaccurate, and the force of each lifting point cannot be controlled, posing a major safety hazard. Summary of the invention

[0006] In order to solve the above problems, the present invention provides an intelligent assembly device for prefabricated subway stations, which is equipped with a jack sensor and can measure the stress conditions of each lifting point in real time. Combined with the intelligent construction method, the present invention provides a more efficient, safe and intelligent solution for the assembly of components of prefabricated subway stations. The lifting points of this equipment adopt a combination of fixed wheels and cross braces.

The device is provided with independent hoisting points, which can be adjusted individually to meet the hoisting requirements of different components, thereby effectively solving the complexity and imbalance of the traditional equipment when the hoisting points are subjected to force at multiple points. Specifically, the device is equipped with a jack sensor, which can measure the force of each hoisting point in real time. Combined with the intelligent construction method, the present invention provides a more efficient, safe and intelligent solution for the assembly of components of assembled subway stations. The hoisting point of the device adopts a combination of fixed wheels and cross braces. Through this design, the friction of the device itself and the influence of the angle change of the wire rope on the force value measured by the jack sensor can be reduced, thereby ensuring the accuracy of the force value measured by the jack sensor. In addition, this combination method also enhances the stability and adaptability of the equipment, and can work efficiently in a variety of working environments.

[0042] Example 1

[0043] The present invention provides an assembled subway station intelligent assembly device, such as Figure 1-Figure 5 As shown, the device is provided with a plurality of lifting systems 3 (corresponding to the number of lifting points of the lifting member 5) on the shoulder pole beam 2, the shoulder pole beam 2 is connected to the gantry crane through the main lifting rope 1, and the lifting system 3 is connected to the lifting member 5 through the wire rope 4. The mechanism principle of the lifting system 3 is as follows: Figure 3 It is an aa section, and the hoisting system 3 is welded on the shoulder pole beam 2. The hoisting system 3 is arranged in pairs before and after the shoulder pole beam 2. The fixed steel plate 10 in the hoisting system 3 is fixed on the top of the shoulder pole beam 2. The strength of the fixed steel plate 10 should be selected according to the weight of the hoisting component 5. Four reinforcing ribs 11 are evenly arranged within the intersection range between the fixed steel plate 10 and the shoulder pole beam 2. The thickness of the reinforcing ribs 11 is the same as that of the fixed steel plate 10. The fixed wheels 14 are placed in the open grooves of the fixed steel plates 10 on both sides of the shoulder pole beam 2. A limiter 12 is arranged above the open groove to prevent the fixed wheels 14 from slipping out of the open grooves of the steel plates 10. When the fixed wheels 14 move to the position of the limiter 12, the jack 16 stops working to ensure the safety of the hoisting system 3. A pallet 13 is arranged below the fixed wheel 14, and the pallet 13 is connected to the shaft of the fixed wheel 14. A jack 16 is connected below the pallet 13. To ensure that the mechanism movement formed by the pallet 13 and the fixed wheel 14 is vertical, a pallet roller 6 is welded on the pallet 13, and a pallet chute 8 is welded on the corresponding fixed steel plate 10, and the pallet roller 6 is placed in the pallet chute 8. A pressure sensor 15 is arranged between the pallet 13 and the jack 16 to monitor the load value of the hoisting system 3.

[0044] Example 2

[0045] Based on Example 1, this embodiment imposes constraints on the design of the wire rope, so that the wire rope does not twist and can only move vertically.

[0046] Specifically, to ensure that the steel wire rope 4 is stressed, the allowable bearing capacity design value of the steel wire rope 4 should satisfy the following formula:

[0047] F1 ≥ βF2 / cos(θ / 2)

[0048] Among them, F1 is the design value of the allowable bearing capacity of the wire rope 4, and F2 is the design value of the load at the component hanging point. β is the safety factor of the wire rope, which is recommended to be no less than 6. θ is the angle of the wire rope.

[0049] Example 3

[0050] Based on Example 1, this embodiment limits the rated range of the jack to ensure the safety of lifting.

[0051] The rated range of the jack 16 should satisfy the following formula:

[0052] F3≥αF2+G

[0053] Among them, F3 is the rated range of a single jack, α is the safety factor of the jack, which is recommended to be no less than 4, and G is the total weight of the fixed wheel 14, the wire rope 4 and the lifting component 5.

[0054] Example 4

[0055] Based on Example 3, this embodiment fixes the jack on the jack fixing steel plate and specifically defines relevant parameters, so as to achieve the transfer of the load of the jack to the shoulder beam.

[0056] Specifically, the jack 16 is fixed on the jack fixing steel plate 17, which is welded on the shoulder pole beam 2. The jack fixing steel plate 17 is composed of two vertical steel plates and one horizontal steel plate. The vertical steel plates are arranged on the front and rear sides of the shoulder pole beam 2, and the horizontal steel plate is arranged below the shoulder pole beam 2. To ensure that the steel wire rope 4 does not conflict with the jack fixing steel plate 17, the distance between the steel plates on both sides of the jack fixing steel plate 17 should be smaller than the diameter of the fixed wheel 14, and a cross brace 18 of the steel wire rope 4 is arranged below the jack fixing steel plate 17. To ensure the stability of the cross brace 18, a cross brace roller 7 is welded on the cross brace, and a cross brace chute 9 is welded on the corresponding shoulder pole beam 2. The steel wire rope 4 is wound around the fixed wheel 14, and the lower end is connected to the hoisting member 5. The length of the steel wire rope 4 is fixed.

[0057] F4 ≥ F3

[0058] Among them, F4 is the reaction force provided by the horizontal steel plate of the jack fixing steel plate 17, and the reaction force is provided by the weld.

[0059] The jack fixing steel plate 17 is composed of two vertical steel plates and one horizontal steel plate. It is connected to the shoulder beam 2 by double-sided fillet welds. The connection between the vertical steel plate and the horizontal steel plate of the jack fixing steel plate 17 is a single-sided fillet weld. The calculation of the weld between the lateral steel plate and the horizontal steel plate is as follows:

[0060]

[0061] Among them, f tw is the fillet weld strength, l w1 is the length of the weld between the horizontal steel plate of the jack fixing steel plate 17 and the shoulder beam, which is a double-sided fillet weld, l w2 is the length of the weld between the vertical steel plate and the horizontal steel plate of the jack fixing steel plate 17, which is a single-sided fillet weld, l w3 is the weld length between the jack fixing steel plate (17) vertical steel plate and the shoulder beam, which is a double-sided fillet weld, and he is the calculated thickness of the fillet weld.

[0062] Example 5

[0063] Based on Example 4, this example makes corresponding settings to ensure that the loads at each hanging point can be adjusted:

[0064]

[0065] Wherein l3 is the stroke of the jack 16. L1 is the length of the slot on the fixed steel plate 10. l2 is the support plate slide 8 and the cross brace slide 9.

[0066] Example 6

[0067] Based on Example 4, this embodiment is designed accordingly to ensure that the steel wire rope is vertical and does not conflict with the steel plate fixed by the jack.

[0068] Specifically, in order to ensure that the steel wire rope 4 is vertical and does not conflict with the jack fixing steel plate 17, the length of the cross brace 18 should satisfy the following formula:

[0069]

[0070] Wherein L2 is the length (mm) of the cross brace 18. D is the inner diameter (mm) of the fixed wheel 14. B4 is the width (mm) of the jack fixing steel plate 17. a is the reserved space, which is usually a constant and is recommended to be no less than 40 mm.

[0071] Example 7

[0072] The present invention also provides a construction method of an assembled subway station intelligent assembly device, comprising the following steps:

[0073] Step 1: Input the design value into the operation platform according to the design value of the component hanging point provided in the design drawing;

[0074] Step 2: The gantry crane moves to the top of the lifting component 5, installs the lifting component 5, and the jacks 16 of each lifting point move upward 20mm to 100mm synchronously to make the lifting component 5 leave the ground. The working steps of a single lifting point in this process are as follows:

[0075] (1) The hoisting member 5 acts on the fixed wheel 14 through the steel wire rope 4. The load adjustment of the lifting point is adjusted by tightening the steel wire rope 4 with the jack 16. The steel wire rope 4 is usually of a fixed length. The upper end of the steel wire rope 4 is annular and wound around the fixed wheel 14, and the lower end is straight and connected to the hoisting member 5.

[0076] (2) The jack 16 pushes the pallet 13, and the pallet 13 pushes the fixed wheel 14 to move upward. When the fixed wheel 14 moves upward, the steel wire 4 is tightened. The fixed wheel 14 is placed on the fixed steel plate 10, and the fixed steel plate 10 is fixed on the shoulder beam 2. If the jack 16 fails during the jacking process, the fixed steel plate 10 will bear the entire load of the fixed wheel 14, so the fixed steel plate 10 needs to add ribs 11 to enhance its stability. There is only one point of action between the jack 16 and the pallet 13. In order to reduce friction during the jacking process and ensure the stability of the pallet 13, 4 groups of pallet chutes 8 and pallet rollers 6 are set. The pallet rollers 6 are symmetrically arranged on both sides of the pallet 13, and the pallet rollers 6 are placed in the pallet chutes 8, respectively. The pallet chutes 8 are arranged on the fixed steel plate 10.

[0077] (3) A pressure sensor 15 is installed between the jack 16 and the support plate 13 to collect the thrust of the jack 16.

[0078] (4) The jack 16 is placed on the jack fixing steel plate 17. The reaction force of the jack 16 is all provided by the jack fixing steel plate 17, and the jack fixing steel plate 17 is welded to the shoulder beam 2.

[0079] (5) In order to ensure that the steel wire rope 4 does not conflict with the jack fixing steel plate 17, a cross brace 18 is provided on the steel wire rope 4 to expand the ring at the upper end of the steel wire rope 4 to form a space for placing the jack fixing steel plate 17. Since the steel wire rope 4 is relatively flexible, a cross brace slide 9 and a cross brace roller 7 are provided on the cross brace 18 to constrain the freedom of the steel wire rope 4 and ensure that the steel wire rope 4 can move vertically in the plane.

[0080] (6) To ensure the reliability of the lifting system 3, a limiter 12 is provided above the fixed steel plate 10. When the displacement of the fixed wheel 14 exceeds a certain value, the jack 16 stops working.

[0081] Step 3: Compare the measured value of the load at each lifting point monitored by the pressure sensor 15 with the design value. If the deviation is greater than the allowable deviation threshold, which is 5% here, the jack 16 oil cylinder is controlled by the operating platform to fine-tune the stroke of the jack 16, thereby adjusting the force of the lifting point. Generally, multiple lifting points are used for lifting. After adjusting the force of one lifting point, the remaining lifting points will also be affected. The load value of each lifting point needs to be continuously adjusted until the deviation between the measured value of the load at each lifting point and the design value is less than 5%.

[0082] Step 4: Lock the stroke of the jack 16, that is, the load size of each lifting point is no longer adjusted, start the main lifting rope 1 of the gantry crane, lift the lifting component 5 to the required height, and then transport the lifting component 5 to the designated position. During this period, if it is found that the measured value of the lifting point exceeds the design value by 5%, it is considered that the movement of the gantry crane makes the load of each lifting point uneven, and the load of the lifting point is not adjusted in this process;

[0083] Step 5: By adjusting the rotation of the shoulder beam 2 and the position of the gantry crane trolley, the hoisting component 5 is accurately placed at the installation position;

[0084] Step 6: Install the lifting component 5;

[0085] Step 7: Remove the hoisting component 5 and install the next hoisting component 5.

[0086] When the lifting system 3 is not working, the load of the lifting component 5 acts on the fixed wheel 14 through the wire rope 4, the fixed wheel 14 is transferred to the fixed steel plate 10, the fixed steel plate 10 is transferred to the shoulder beam 2, and the shoulder beam 2 is transferred to the gantry crane structure through the main lifting rope 1.

[0087] When the hoisting system 3 is working, the load of the hoisting component 5 is transferred to the jack 16 through the wire rope 4 and the fixed wheel 14, and the jack 16 transfers the load to the shoulder pole beam 2 through the jack fixing steel plate 17, and the shoulder pole beam 2 transfers the load to the gantry crane structure through the main hoisting rope 1.

[0088] When the hoisting system 3 is working, the pressure sensor 15 is working at the same time. To ensure the accuracy of the data collected by the pressure sensor 15, the stabilizing auxiliary measures of each hoisting component 5 are connected in the form of rollers and slideways.
