Description

Technical Field

[0001] The invention relates to the field of assembled sound barrier construction, and in particular to a roof sound insulation board hoisting system and a hoisting method for an assembled sound barrier. Background Art

[0002] Fully enclosed sound barriers are an environmental protection facility used to reduce railway noise, especially in high-speed railways and elevated roads. Fully enclosed sound barriers significantly reduce noise transmission through their structural design. Compared with traditional upright sound barriers, fully enclosed sound barriers can more effectively reduce the impact of noise on the surrounding environment, especially for sensitive areas along the line such as schools and hospitals.

[0003] As an advanced noise reduction measure, fully enclosed sound barriers not only effectively reduce the impact of railway noise on the surrounding environment, but also show significant advantages in ecological protection and wind load bearing. With the continuous advancement of technology and the promotion of its application, fully enclosed sound barriers will play an important role in more fields in the future and contribute to the construction of a more harmonious environment.

[0004] However, the existing fully enclosed sound barriers have the following problems when constructing roof sound insulation panels:

[0005] (1) When there is space under the roof sound insulation board for heavy cranes to move and hoist into place, heavy crane lifting is undoubtedly the most convenient and direct method. However, when hoisting sound insulation boards on the roof of the existing railway line, the space under the roof sound insulation board cannot be occupied, and the hoisting can only be carried out outside the sound barrier. At this time, the hoisting radius is particularly large, and the required crane tonnage is very large, which is not only expensive, but also has strict requirements on the construction space, and it is difficult to meet the construction conditions;

[0006] (2) Traditional jacking is generally just a simple high-altitude jacking of components, which requires a larger installation platform. The jacking direction must be hoisted in place before jacking can be achieved. When the lifting radius is too large, a light crane cannot be used. When the crane tonnage and lifting radius are too large, the lifting cost is too high, which is not economical and the construction conditions are difficult to meet.

[0007] Therefore, how to propose solutions to the above problems has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a system and method for hoisting a roof sound insulation board of an assembled sound barrier. The column top frame beam and the connecting steel beam mechanism of the present invention form a high and low staggered basic track that is compatible with the sliding of the portal hanger mechanism, and then the portal hanger mechanism is adjusted by multiple groups of alternately retracted supporting legs to achieve staggered movement, so that the portal hanger mechanism can move across the beam, thereby improving the hoisting efficiency of the roof sound insulation board. During the construction of the patent, the site does not need to occupy the space of the railway line, and the construction needs can be met according to the key points of the normal existing line, and there is no need to rigidly close the railway line, which has great promotion value.

[0009] The present invention is achieved through the following technical solutions:

[0010] A roof sound insulation board hoisting system of an assembled sound barrier, the assembled sound barrier comprises columns, sound insulation wall panels, column top frame beams, roof truss beams and roof sound insulation boards, the columns are symmetrically arranged on the left and right sides of a double-track railway, and the lower ends of the columns are fixedly connected to the foundation, the sound insulation wall panels are arranged on the outer side of the columns, the column top frame beams are fixedly connected to the upper ends of the columns, the lower side of the roof truss beams are connected to the column top frame beams, the roof sound insulation boards are fixedly laid on the upper surface of the roof truss beams, and the roof sound insulation board hoisting system is used for hoisting and constructing the roof sound insulation boards, and comprises a door-type hanger mechanism, a connecting steel beam mechanism and a jacking mechanism, wherein;

[0011] The gantry hanger mechanism includes two groups of symmetrically arranged gantry units, multiple groups of transverse support beams arranged in the vertical direction of the track, and multiple groups of sliding lifting assemblies. The gantry unit includes a longitudinal support beam arranged along the track and multiple groups of alternately telescopic support legs. The transverse support beam is vertically fixedly connected to the longitudinal support beam, the upper end of the support leg is vertically fixedly connected to the end of the longitudinal support beam, the lower end of the support leg is against the column top frame beam or the connecting steel beam mechanism, and the lower end of the support leg moves along the upper surface of the column top frame beam or the connecting steel beam mechanism, the sliding lifting assembly is slidably connected to the transverse support beam, and the sliding lifting assembly is used for hoisting and constructing the roof sound insulation board;

[0012] The connecting steel beam mechanism includes a plurality of connecting steel beam assemblies, which are fixedly arranged between two groups of roof beams, and the upper surface of the connecting steel beam assembly is provided with a guide rail unit adapted to the lower end of the supporting leg;

[0013] The jacking mechanism includes two sets of jacking assemblies symmetrically arranged on the column top frame beams, multiple sets of roof truss beams hoisted in place, roof sound insulation panels laid on the roof truss beams and multiple sets of connecting steel beam assemblies as a whole to form a jacking structure. The two sets of jacking assemblies cooperate to drive the jacking structure to the installation position.

[0014] It can be seen that in the above technical scheme, the column top frame beam and the connecting steel beam mechanism of the present invention form a high and low staggered basic track that is compatible with the sliding of the portal hanger mechanism, and then the multiple groups of alternately retractable supporting legs of the portal hanger mechanism are used to achieve staggered movement and adjustment, so that the portal hanger mechanism can move across the beam, thereby improving the hoisting efficiency of the roof sound insulation board; this patent includes multiple groups of transverse support beams arranged in the vertical direction of the track, so that multi-point bidirectional simultaneous lifting can be achieved, thereby improving the hoisting efficiency and meeting the requirements of short hoisting time for existing lines; during the construction of this patent, the site does not need to occupy the space of the railway line, and it is unnecessary to carry out large-area formwork structure support. The amount of turnover materials and the number of operating workers are small. The construction needs can be met by constructing according to the key points of the normal existing line, and there is no need to rigidly close the railway line.

[0015] According to the above technical solution, preferably, it also includes a push monitoring subsystem, which includes multiple groups of pressure sensors, signal transmitters, signal receivers, processing terminals and alarms, wherein;

[0016] The pressure sensor is arranged on the connecting steel beam assembly, and is used to sense the deformation of the connecting steel beam assembly to generate a deformation numerical variable, and send it to the signal receiver through the signal transmitter;

[0017] The signal receiver is electrically connected to the processing terminal, and a safety monitoring model is built into the processing terminal. When the fluctuation range of the deformation value variable exceeds a set threshold, an alarm signal is generated;

[0018] The alarm is electrically connected to the processing terminal, and the alarm sounds an alarm according to the alarm signal.

[0019] It can be seen that in the above technical solution, during normal jacking construction, the jacking assembly gradually applies pressure to the connecting steel beam assembly until the jacking structure begins to slide gradually. At this time, the connecting steel beam assembly gradually tends to a stable range. When there are structural changes in the jacking structure, the connecting steel beam assembly at this time will fluctuate accordingly. By setting up a safety monitoring model, the accuracy and timeliness of existing human eye observation can be effectively improved, which facilitates early adjustments and improves construction safety.

[0020] According to the above technical solution, preferably, the transverse support beam extends along the vertical track to the outside of the column, and the sliding lifting assembly can slide to the outside of the assembled sound barrier to hoist the roof sound insulation board.

[0021] It can be seen that in the above technical solution, the sliding lifting assembly can slide to the outside of the assembled sound barrier to hoist the roof sound insulation board, thereby greatly improving the hoisting efficiency.

[0022] According to the above technical solution, preferably, the sliding lifting assembly is an electric hoist or a hand hoist.

[0023] According to the above technical solution, preferably, the supporting legs are hydraulic telescopic columns or electric telescopic columns.

[0024] According to the above technical solution, preferably, the two ends of the connecting steel beam assembly are detachably fixedly connected to the side surfaces of the roof truss beam.

[0025] According to the above technical solution, preferably, the lower end of each group of supporting legs is provided with a roller and a driving motor that resists the guide rail unit, the roller is rotatably connected to the lower end of the supporting leg, the driving motor is externally fixed on the outside of the supporting leg, and the driving motor drives the roller to rotate.

[0026] The present invention also discloses a method for hoisting a roof sound insulation board of an assembled sound barrier, which adopts the above-mentioned roof sound insulation board hoisting system of the assembled sound barrier, and comprises the following steps:

[0027] Step 1, hoisting roof beams: in the hoisting construction area, hoist multiple groups of roof beams onto the column top frame beams, and the design spacing of adjacent roof beams is set to the space spacing of a single group of roof beams, and the ends of the roof beams are slidably connected to the column top frame beams;

[0029] Step 3, the portal hanger mechanism is adjusted to be directly above the roof beam on which the roof sound insulation board is to be hoisted: multiple groups of support legs of the portal unit move along the upper surface of the column top frame beam or the connecting steel beam mechanism, and the support legs are alternately telescopically adjusted, so that the portal hanger mechanism is adjusted to be directly above the roof beam on which the roof sound insulation board is to be hoisted;

[0030] Step 4, hoisting the roof sound insulation board onto the roof beam: the sliding lifting assembly hoists the roof sound insulation board, and the sliding lifting assembly drives the roof sound insulation board to slide along the transverse support beam until the hoisting of multiple groups of roof sound insulation boards is completed. At this time, the roof sound insulation board is not hoisted in the connecting steel beam assembly area. The multiple groups of roof beams hoisted in place, the roof sound insulation boards laid on the roof beams, and the multiple groups of connecting steel beam assemblies form a top-pushing structure as a whole;

[0031] Step 5, the gantry hanger mechanism is adjusted to leave the jacking structure: the support legs of the gantry unit are adjusted to be telescopic alternately, and the gantry hanger mechanism is translated along the column top frame beam, so that the gantry hanger mechanism is adjusted to leave the top of the jacking structure in step 4;

[0032] Step 6, jacking construction of jacking mechanism: two jacking components of the jacking mechanism are installed on the column top frame beam. At this time, the two jacking components cooperate to drive the jacking structure of step 4 to the installation position. At this time, a space spacing of a single set of roof truss beams is left between the two sets of jacking structures in place;

[0033] Step 7, the portal hanger mechanism is adjusted and moved to the top of the single set of roof beams reserved in step 6: the supporting legs of the portal unit are adjusted and extended alternately, and the portal hanger mechanism is translated along the column top frame beam, so that the portal hanger mechanism is adjusted and moved to the top of the single set of roof beams reserved in step 6;

[0035] The beneficial effects of the present invention are:

[0036] (1) The column top frame beam and the connecting steel beam mechanism of the present invention form a high and low staggered basic track that is compatible with the sliding of the portal hanger mechanism, and then the portal hanger mechanism can be staggered and adjusted through multiple groups of alternately retracted support legs, so that the portal hanger mechanism can move across the beam, thereby improving the hoisting efficiency of the roof sound insulation board;

The amount of turnover materials and the number of operating workers are small. The construction needs can be met by following the key points of the normal existing line, and there is no need to rigidly close the railway line. BRIEF DESCRIPTION OF THE DRAWINGS
