Description

Technical Field

[0001] The utility model application relates to the technical field of barrier column auxiliary installation, in particular to an auxiliary installation device for railway roadbed sound barrier columns. Background Art

[0002] The railway project will pass through villages, residential areas, kindergartens, schools and other buildings that are sensitive to noise.

[0003] Usually, sound barriers are set up in areas passing through noise-sensitive buildings to reduce the spread of high-speed rail and train noise, reduce the impact of traffic noise on nearby residents, and achieve traffic sound insulation. The sound barrier is mainly composed of two parts: steel structure columns and sound-absorbing and sound-insulating screen panels. The columns are the main load-bearing components of the sound barrier, and the sound-absorbing and sound-insulating panels are the main sound-insulating and sound-absorbing components.

[0004] In the construction of sound barrier columns in existing roadbed projects, they are usually processed in the factory and transported to the construction site. The sound barrier columns are lifted by a truck crane to the pre-buried position of the sound barrier foundation, and then manually positioned and fastened (the non-metallic sound barrier columns are fixed by pouring fine stone concrete). This process is not continuous, and 5 to 6 people are required to participate in the installation. The labor cost is high, the rental fee of the truck crane is high, and it is difficult to adjust the sound barrier columns when the truck crane is installed. At the same time, the working space required for the truck crane construction is large, which affects the smooth passage of the beam transportation channel, and thus affects the construction period of the project. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide an auxiliary installation device for railway roadbed sound barrier columns to solve the technical problems mentioned in the above background technology, such as high labor costs, high rental fees of mobile cranes, and difficulty in adjusting the sound barrier columns when lifting them by mobile cranes. At the same time, the working space required for the construction of mobile cranes is large, which affects the smooth flow of beam transportation channels and thus affects the construction period of the project.

[0006] The above-mentioned purpose of this application is achieved through the following technical solutions:

[0007] An auxiliary installation device for railway roadbed sound barrier columns, comprising a mounting frame movable on the roadbed shoulder, a horizontal suspension rod being arranged at the upper end of the mounting frame, both ends of the horizontal suspension rod being movably mounted on the mounting frame, a lifting piece being mounted on the horizontal suspension rod, a traction rope being mounted on the lifting piece, one end of the traction rope being connected to a lifting hook for lifting the sound barrier column, a lifting rope being movably connected to the lifting hook, and the lifting rope being movably connected to the sound barrier column through a lifting hole provided on the sound barrier column.

[0008] By adopting the above technical scheme, the sound barrier columns are placed in the pit reserved for the main foundation, and the installation workers move the auxiliary installation device for the sound barrier columns to the top of the sound barrier columns, so that the sound barrier columns are placed inside the auxiliary installation device for the sound barrier columns, adjust the horizontal hanger to make it perpendicular to the top of the sound barrier columns, and then hang the lifting rope into the hook, operate the traction rope to lift the sound barrier columns, and the bottom of the lifted sound barrier columns is manually adjusted by the workers to make it consistent with the installation position in the reserved pit and then fixed. This auxiliary installation device for sound barrier columns is suitable for non-metallic sound barrier columns and transparent sound barrier columns for roadbeds, and has the advantages of easy installation, reliable use and easy operation. The number of installation workers required is reduced by only 2-3, which effectively reduces labor costs, and at the same time reduces the use time of the truck crane, greatly improves labor efficiency and saves construction costs, and the construction of this device occupies a small space, and the working surface range is located on the roadbed shoulder, which can ensure the smooth passage of the beam transportation and addition and has no impact on other working surfaces under construction at the same time, improves working efficiency, and has certain application value.

[0009] A further optimization scheme is that adjustment brackets are installed at the four corners of the bottom surface of the mounting frame, the external threads arranged on the adjustment brackets cooperate with the internal threads arranged at the four corners of the mounting frame, and locking nuts are installed on the adjustment brackets.

[0010] By adopting the above technical solution, when the sound barrier column auxiliary installation device lifts the sound barrier column, in order to keep the sound barrier column parallel to the main reserved pit for better installation, adjustment brackets are installed at the four corners of the bottom surface of the mounting frame. The external threads on the adjustment brackets cooperate with the internal threads at the four corners of the mounting frame. In this way, when the bottom surface of the sound barrier column is not parallel to the main reserved pit, the level of the sound barrier column can be adjusted by adjusting the brackets, so that it is convenient to install it in the main reserved pit.

[0011] According to a further optimization scheme, one end of the adjustment bracket away from the mounting frame is fixedly connected to a universal wheel with a locking device for driving the mounting frame to move.

[0012] By adopting the above technical solution, in order to conveniently and quickly move the sound barrier column auxiliary installation device to the top of the main reserved pit, universal wheels with locking devices are installed at the four corners of the bottom surface of the mounting frame, so that the sound barrier column auxiliary installation device can be conveniently and quickly moved to the top of the main reserved pit where the sound barrier column is required to be installed for installation, and the locking device on the universal wheel can effectively fix the sound barrier column auxiliary device, thereby preventing the sound barrier column auxiliary device from moving during the installation of the sound barrier column.

[0013] According to a further optimization scheme, fixing rods are installed on both sides of the mounting frame, and both ends of the fixing rods are connected to the mounting frame.

[0014] By adopting the above technical solution, in order to maintain the stability of the mounting frame, fixing rods are installed on both sides of the mounting frame, and both ends of the fixing rods are connected to the mounting frame, thereby achieving the stability of the mounting frame.

[0015] According to a further optimization scheme, support rods are provided on opposite sides of the mounting frame, one end of the support rods is detachably connected to the mounting frame, and the other end is supported on the ground.

[0016] By adopting the above technical solution, in order to prevent the mounting frame from tipping over, support rods are provided on opposite sides of the mounting frame, one end of the support rods is detachably connected to the mounting frame, and the other end is supported on the ground, thereby ensuring the stability of the mounting frame during operation and preventing the mounting frame from tipping over due to the shaking of the sound barrier pillars during operation.

[0017] According to a further optimization scheme, a plurality of fixing rods are provided, and the plurality of fixing rods cross each other.

[0018] By adopting the above technical solution, multiple fixing rods are arranged on both sides of the mounting frame, and the fixing rods are crossed, and multiple triangular structures are formed between the multiple fixing rods and the mounting frame. As is known to all, the triangle is a stable structure, so that the mounting frame remains stable during operation.

[0019] A further optimization solution is that the height of the horizontal hanger from the ground is higher than the height of the upper end of the sound barrier column from the ground.

[0020] By adopting the above technical solution, in order to conveniently move the mounting frame to the sound barrier column, the height of the horizontal hanger from the ground is higher than the height of the upper end of the sound barrier column from the ground. In this way, when the mounting frame is moved on the roadbed and shoulder, the sound barrier column placed in the main reserved pit can easily penetrate into the interior of the mounting frame.

[0021] According to a further optimized solution, the lifting member is a bidirectional self-locking pulley.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the installation frame, horizontal lifting rod, lifting parts, traction rope, lifting hook and lifting rope, the sound barrier columns placed in the reserved pits can be easily lifted and installed manually. The sound barrier column auxiliary installation device is suitable for non-metallic sound barrier columns and transparent sound barrier columns on the roadbed. It has the advantages of easy installation, reliable use and easy operation. The required installation workers are reduced to 2-3 people, which effectively reduces labor costs and reduces the use time of automobile cranes, greatly improves labor efficiency and saves construction costs. In addition, the construction of this device occupies a small space, and the working surface is located on the roadbed shoulder, which can ensure the smooth passage of beam transportation and has no impact on other working surfaces of the same period, improves working efficiency, and has certain application value.

[0024] 2. The mounting frame can be adjusted horizontally through the adjustable bracket, so that the sound barrier column remains parallel to the reserved pit after lifting, making it convenient for the staff to install it.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] Example, see Figure 1The invention discloses an auxiliary installation device for railway roadbed sound barrier columns, comprising a mounting frame 1 movable on the roadbed shoulder, the mounting frame 1 being composed of four vertical bars 10 and a plurality of horizontal bars 11 movably connected by a connecting piece 15, and the plurality of horizontal bars 11 on both sides are parallel to each other, a horizontal suspension rod 2 is installed between the opposite horizontal bars 11 at the upper end of the mounting frame 1, and the two ends of the horizontal suspension rod 2 are movably installed on the horizontal bars 11, that is, the horizontal suspension rod 2 is installed between the two horizontal bars 11 and can move back and forth on the two horizontal bars 11, and a horizontal suspension rod 2 is installed on the horizontal suspension rod 2. A lifting component 3 is installed. In the present embodiment, the lifting component 3 is a bidirectional self-locking pulley, but it is not limited thereto. Any lifting component 3 that can perform the lifting function and is convenient for workers to operate can be used. The bidirectional self-locking pulley is sleeved on the horizontal suspension rod 2 and droops naturally. A traction rope 4 is sleeved on the bidirectional self-locking pulley. One end of the traction rope 4 is connected to a lifting hook 5 for lifting the sound barrier column 16. A lifting rope 6 is movably connected to the lifting hook 5. The lifting rope 6 is movably connected to the sound barrier column 16 through a lifting hole opened on the sound barrier column 16.

[0033] In the embodiment of the present disclosure, since the mounting frame 1 is placed on the roadbed or the shoulder, if the roadbed or the shoulder is not horizontal, the suspended sound barrier column 16 may not be vertical, resulting in the sound barrier column 16 not being able to be conveniently installed in the reserved pit. Adjustment brackets 7 are installed at the four corners of the bottom surface of the mounting frame 1, that is, adjustment brackets 7 are installed at the bottom of the four vertical rods 10, and the external thread provided on the adjustment bracket 7 cooperates with the internal thread provided on the vertical rod 10. When adjustment is required, the adjustment bracket 7 is rotated to adjust the horizontal state of the mounting frame 1, and then locked by the locking nut 17.

[0034] In the embodiment of the present disclosure, a universal wheel 8 that can drive the mounting frame 1 to move is fixedly connected to the end of the adjustment bracket 7 away from the mounting frame 1, and the universal wheel 8 is provided with a locking device 9. In actual work, the four universal wheels 8 can drive the mounting frame 1 to move, and the mounting frame 1 can be easily moved to the reserved groove where the sound barrier column 16 is required to be installed. The universal wheel 8 can be locked by the locking device 9 on the universal wheel 8, thereby locking the position of the mounting frame 1 to prevent the mounting frame 1 from moving when the sound barrier column 16 is hoisted and installed.

[0035] In this public embodiment, due to the gravity of the sound barrier column 16, the mounting frame 1 may cause the structure of the fixing frame to be unstable when hoisting the sound barrier column 16. Fixed rods 13 are installed on both sides of the mounting frame 1. The two ends of the fixed rods 13 are welded to the mounting frame 1 or connected through a connecting piece 15 (not shown in the accompanying drawings), and multiple fixed rods 13 are installed and cross-linked with each other. The crossed fixed rods 13 can be locked at the intersection by the connecting piece 15. Multiple triangular structures are formed between the multiple fixed rods 13 and the mounting frame 1. The triangular structure is a stable structure, so that the mounting frame 1 remains stable during operation.

[0036] In the embodiment of the present disclosure, support rods 14 are provided on opposite sides of the mounting frame 1, one end of the support rod 14 is detachably connected to the mounting frame 1, and the other end is supported on the ground. By installing the support rods 14 at both ends of the mounting frame 1, the stability of the mounting frame 1 during operation can be ensured, and the mounting frame 1 can be prevented from tipping over due to the shaking of the sound barrier column 16 during operation.

[0037] In the embodiment of the present disclosure, in order to conveniently move the mounting frame 1 to the top of the sound barrier column 16, the height of the horizontal hanger 2 from the ground is higher than the height of the upper end of the sound barrier column 16 from the ground. In this way, when the mounting frame 1 is moved on the roadbed shoulder, the sound barrier column 16 placed in the main reserved pit can be easily inserted into the interior of the mounting frame 1, making it convenient to lift the sound barrier column 16.

[0038] Specific implementation process; installation steps of sound barrier columns:

[0039] 1. After the sound barrier column 16 is processed in the factory, it is transported to the construction site and a truck crane is used to lift the sound barrier column 16 into the reserved pit:

[0040] 2. Before starting to hoist the sound barrier column 16, dismantle the horizontal bar 11 on one side of the mounting frame 1, push the auxiliary mounting device of the sound barrier column 16 to the placement position of the sound barrier column 16, lock the universal wheel 8 through the locking device 9, reinstall the horizontal bar 11 on one side of the mounting frame 1 to the mounting frame 1, and adjust the bracket 7 to level the device according to the barrier degree of the roadbed or shoulder site;

[0041] 3. Lower the hook, pass the lifting rope 6 through the reserved lifting hole on the sound barrier column 16 and hang it on the hook;

[0042] 4. After the worker pulls the traction rope 4 to lift the sound barrier column 16 to a vertical state through the two-way self-locking pulley, the locking device 9 is released. The worker adjusts the verticality and elevation of the sound barrier column 16 by pushing the mounting frame 1 and the two-way self-locking pulley. After reaching the installation standard, the universal wheel 8 is locked by the locking device 9. After positioning the sound barrier column 16 with positioning steel bars, fine stone concrete is poured (for non-metallic sound barrier columns 16), or the base of the sound barrier column 16 and the reserved groove are locked with fixing nuts (for transparent sound barrier columns 16).

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
