Description

Technical Field

[0001] The present invention relates to the field of hoisting construction of a roof truss structure of an assembled sound barrier, and in particular to a bidirectional sliding hoisting system and a hoisting method of a roof truss structure of 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 truss structures:

[0005] (1) When there is space under the sound barrier roof structure for heavy cranes to travel and hoist into place, heavy crane lifting is undoubtedly the most convenient and direct method. However, when hoisting the sound barrier roof structure on an existing railway line, the space under the roof structure 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, making it 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 shortcomings existing in the prior art and to provide a bidirectional sliding lifting system and lifting method for the roof truss structure of an assembled sound barrier. The main structural components of this patent are all prefabricated in the factory, and do not need to occupy the railway line space on site, and are free from large-area formwork structure support. The amount of turnover materials and the number of operating workers are small. This patent optimizes the outer guide frame mechanism, the inner guide frame mechanism and the shifting mechanism, so that the lifting system of this patent has the function of bidirectional sliding roof truss beams.

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

[0010] The bidirectional sliding hoisting system of the roof truss structure of the assembled sound barrier includes an outer guide frame mechanism, an inner guide frame mechanism and a shifting mechanism, wherein;

[0011] The outer guide frame mechanism is fixedly arranged outside the railway line, and is used to temporarily place the roof truss structure. The outer guide frame mechanism includes at least two sets of parallel first support beams and fixed brackets, and the fixed brackets are fixed to the ground outside the railway line. The axis direction of the first support beam is perpendicular to the railway track. The first support beam is fixedly connected to the fixed bracket, and the roof truss structure is placed on the fixed bracket between the two sets of first support beams.

[0012] The inner guide frame mechanism includes at least two sets of parallel second support beams and multiple sets of beam trolley assemblies. The second support beams are arranged directly above the railway. The two ends of the lower side of the second support beams are slidably connected to the column top frame beams. The axial direction of the second support beams is perpendicular to the railway track. The second support beams are connected to the first support beams. The beam trolley assembly is arranged on the upper side of the second support beams. The beam trolley assembly is slidably connected to the second support beams and the first support beams along the vertical track direction. The multiple sets of beam trolley assemblies cooperate to drive the roof frame structure to transfer from the outer guide frame mechanism to the inner guide frame mechanism along the vertical track direction. The two sets of second support beams drive the beam trolley assembly and the roof frame structure to slide along the track direction to the set installation position.

[0013] The shifting mechanism includes at least two groups of symmetrically arranged shifting components, which are slidably connected to the column top frame beam. The shifting components include a third support beam, a fourth support beam, multiple groups of shifting vehicles and multiple groups of telescopic columns. The lower side of the third support beam is slidably connected to the column top frame beam, and the fourth support beam is located on the upper side of the third support beam. One end of the shifting vehicle is adjustably plug-connected to the fourth support beam. The telescopic columns correspond to the shifting vehicle one by one, and the telescopic columns are fixedly connected to the other end of the shifting vehicle. The telescopic columns are vertically arranged, and the lower ends of the telescopic columns are against the upper end surface of the column top frame beam. The sum of the heights of the third support beam and the fourth support beam is greater than the sum of the heights of the second support beam and the roof truss structure. The shifting vehicle hoists the second support beam on the outside of the roof truss structure that has been moved into place to the inside of the roof truss structure.

[0014] It can be seen that in the above technical scheme, the main frame structure of this patent adopts an assembled design, and the main structural components are all prefabricated in the factory. There is no need to occupy the railway line space on site, and it is unnecessary to carry out large-area formwork structure support. The turnover material consumption and the operating workers consumption are small. The vertical transportation of the structural components of this patent adopts a mobile automobile crane or a crawler crane for installation. It has a high level of marketization and can be flexibly applied according to the site conditions. It does not require the installation of a special tower crane, and the lifting efficiency is relatively high. In the lifting process adopted by this patent, the most difficult roof frame component is first lifted by a automobile crane or a crawler crane to the outer guide frame mechanism, and then slid along the track to the designed position through the inner guide frame mechanism. It takes less time and has good safety. The construction needs can be met by following the normal existing line key points, and there is no need for rigid closure of the railway line. This patent optimizes the outer guide frame mechanism, the inner guide frame mechanism and the shifting mechanism, so that the lifting system of this patent has the function of bidirectional sliding roof truss beams.

[0015] According to the above technical solution, preferably, the fourth support beam is slidably connected to the upper sides of the third support beam and the second support beam along the track.

[0016] It can be seen that in the above technical solution, since the fourth support beam can be slidably connected to the upper sides of the third support beam and the second support beam along the track, when the roof frame components are hoisted into place, the third support beam drives the fourth support beam to slide along the track to the side of the third support beam. At this time, subsequent operations can be carried out. The shifting vehicle will hoist the second support beam on the outside of the roof truss structure that has been moved into place to the inside of the roof truss structure, thereby effectively shortening the length of the shifting vehicle and improving operating efficiency and construction safety.

[0017] According to the above technical solution, preferably, the crane beam vehicle assembly includes two groups of first slide units, a first support arm and multiple groups of lifting units. The lower side of the first slide unit is slidably connected to the first support beam and the second support beam along the vertical track direction. The first support arm is detachably fixedly connected to the first slide unit. Multiple groups of lifting units are arranged on the first support arm, and the multiple groups of lifting units cooperate to lift the roof truss structure.

[0018] It can be seen that in the above technical solution, the two ends of the first support arm are fixedly connected to the two groups of first slide units respectively. At this time, the lifting unit arranged on the first support arm cooperates with the lifting roof truss structure, and multiple groups of crane beam car assemblies move synchronously, thereby realizing the translation of the roof truss structure along the vertical track direction.

[0019] According to the above technical solution, preferably, the shifting vehicle includes a second support arm and multiple groups of lifting units, one end of the second support arm is detachably fixedly connected to the fourth support beam, the lifting unit is arranged on the second support arm, and the multiple groups of lifting units cooperate to lift the second support beam.

[0020] It can be seen that in the above technical solution, the lifting unit is arranged on the second support arm, and the lifting unit can be slidably connected to the second support arm. When the second support beam needs to be lifted, one end of the second support arm is detachably fixedly connected to the fourth support beam, and the telescopic column is fixedly connected to the other end of the second support arm, and the lower end of the telescopic column is against the upper end surface of the column top frame beam, so that multiple sets of lifting units cooperate to lift the second support beam and transfer it to the other side across the roof truss structure.

[0021] According to the above technical solution, preferably, the telescopic column is a hydraulic telescopic column or an electric telescopic column.

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

[0023] The present invention also discloses a bidirectional sliding hoisting method for a roof truss structure of an assembled sound barrier, which adopts the bidirectional sliding hoisting system for the roof truss structure of the assembled sound barrier, and comprises the following steps:

[0024] Step 1, assembling the outer guide frame mechanism: erecting two sets of first support beams and fixed brackets of the outer guide frame mechanism outside the railway line, the two sets of first support beams are fixedly connected to the fixed brackets, and the axis direction of the first support beam is perpendicular to the railway track;

[0025] Step 2, assembling the inner guide frame mechanism: pre-assemble the second support beam and multiple sets of beam crane assemblies on the ground, and use a crane to lift the second support beam and multiple sets of beam crane assemblies onto the column top frame beam, at this time, the two ends of the lower side of the second support beam are slidably connected with the column top frame beam, and the axis direction of the second support beam is perpendicular to the railway track;

[0026] Step 3, assembling the shifting mechanism: pre-assemble the third support beam, the fourth support beam, multiple shifting vehicles and multiple telescopic columns of the shifting assembly on the ground, and use a crane to hoist them to the column top frame beam, at which time the lower side of the third support beam is slidably connected to the column top frame beam;

[0027] Step 4, hoisting the roof truss structure to the outer guide frame mechanism: using a crane to hoist the roof truss structure between the two sets of first support beams, the second support beam is connected to the first support beam, the beam hoisting vehicle assembly slides onto the first support beam, and hoists the roof truss structure;

[0028] Step 5, the roof truss structure is transferred to the inner guide frame mechanism: along the vertical direction of the rail, the beam crane assembly drives the roof truss structure to slide onto the two sets of second support beams of the inner guide frame mechanism. At this time, the roof truss structure is located directly above the railway;

[0029] Step 6: The second support beam drives the roof truss structure to move horizontally to the installation position along the track: along the track direction, the two sets of second support beams drive the beam crane assembly and the roof truss structure to slide along the upper end of the column top frame beam until the roof truss structure reaches the installation position, and installs the roof truss structure to the set position;

[0030] Step 7, the shifting assembly hoists the second support beam on the outside of the roof truss structure that has been moved to the inside of the roof truss structure: the shifting assembly moves horizontally along the track to the second support beam, the shifting vehicle drives the telescopic column to extend to the outside of the roof truss structure, and the telescopic column stretches and abuts against the upper end of the column top frame beam; the shifting vehicle hoists the second support beam on the outside of the roof truss structure that has been moved to the inside of the roof truss structure;

[0031] Step 8: Return the inner guide frame mechanism and the shifting mechanism to their original positions, and repeat steps 4 to 7 to complete the installation of the roof truss structure of the assembled sound barrier.

The bidirectional sliding hoisting method of the roof truss structure of the assembled sound barrier is characterized by: The bidirectional sliding hoisting system of the roof truss structure of the assembled sound barrier according to claim 1 comprises the following steps: Step 1, assembling the outer guide frame mechanism: erecting two groups of first support beams and fixed brackets of the outer guide frame mechanism outside the railway line, the two groups of first support beams are fixedly connected to the fixed brackets, and the axis direction of the first support beam is perpendicular to the railway track; Step 2, assembling the inner guide frame mechanism: pre-assemble the second support beam and multiple sets of beam crane assemblies on the ground, and use a crane to lift the second support beam and multiple sets of beam crane assemblies onto the column top frame beam, at this time, the two ends of the lower side of the second support beam are slidably connected with the column top frame beam, and the axis direction of the second support beam is perpendicular to the railway track; Step 3, assembling the shifting mechanism: pre-assemble the third support beam, the fourth support beam, multiple shifting vehicles and multiple telescopic columns of the shifting assembly on the ground, and use a crane to hoist them to the column top frame beam, at which time the lower side of the third support beam is slidably connected to the column top frame beam; Step 4, hoisting the roof truss structure to the outer guide frame mechanism: using a crane to hoist the roof truss structure between the two sets of first support beams, the second support beam is connected to the first support beam, the beam hoisting vehicle assembly slides onto the first support beam, and hoists the roof truss structure; Step 5, the roof truss structure is transferred to the inner guide frame mechanism: along the vertical direction of the rail, the beam crane assembly drives the roof truss structure to slide onto the two sets of second support beams of the inner guide frame mechanism. At this time, the roof truss structure is located directly above the railway; Step 6: The second support beam drives the roof truss structure to move horizontally to the installation position along the track: along the track direction, the two sets of second support beams drive the beam crane assembly and the roof truss structure to slide along the upper end of the column top frame beam until the roof truss structure reaches the installation position, and installs the roof truss structure to the set position; Step 7, the shifting assembly hoists the second support beam on the outside of the roof truss structure that has been moved to the inside of the roof truss structure: the shifting assembly moves horizontally along the track to the second support beam, the shifting vehicle drives the telescopic column to extend to the outside of the roof truss structure, and the telescopic column stretches and abuts against the upper end of the column top frame beam; the shifting vehicle hoists the second support beam on the outside of the roof truss structure that has been moved to the inside of the roof truss structure; Step 8: Return the inner guide frame mechanism and the shifting mechanism to their original positions, and repeat steps 4 to 7 to complete the installation of the roof truss structure of the assembled sound barrier.
