Description

Technical Field

[0001] The invention relates to the field of water conservancy and hydropower engineering plant system construction, and in particular to a movable underground plant steel bar mechanized construction platform vehicle. Background Art

[0002] In the underground plant layout of a pumped storage power station project, since there are a few geological fault zones in the plant area that cannot be avoided, mechanical layered and block excavation is required, and a large number of steel bars, steel beams, and anchor cables are added for reinforced support. Therefore, mechanical block excavation is adopted to provide a working environment for the collaborative construction of various equipment. However, since all anchor cables and steel bars for reinforced support need to be installed simultaneously during layered excavation, relying on traditional manual installation, more than ten workers are required to work together, the construction cost is high and there are high safety hazards. At the same time, due to the complex process of steel bar construction, including drilling, installation, grouting, tensioning, and anchor head fixing, the overall construction period is long. If mechanized construction can be carried out from the installation process, the overall process time will be greatly shortened.

[0003] For the installation and construction of such steel bars at home and abroad, there are usually two methods:

[0004] 1. Pre-assembly: For relatively short steel bars, they can generally be pre-assembled in parts off-site. The general construction process is primary processing by the manufacturer, transportation to the site, secondary assembly and pre-tightening at the processing plant, secondary transportation, hoisting and installation. The steel bars are already finished products during hoisting, and the total length is generally within 25m. Generally, two cranes with a total of 4 lifting points are used for hoisting to ensure deflection, tilt and slowly lift, and manual fall chains and crowbars are used to assist in adjusting them into place for installation.

[0005] 2. Hoisting and assembly: For relatively long steel bars, they are generally pre-assembled in sections off-site and spliced ​​during hoisting. The general construction process is primary processing by the manufacturer, transportation to the site, secondary assembly and pre-tightening at the processing plant, secondary transportation, hoisting and installation, hoisting the next section of steel bars, and on-site splicing. The total length of the steel bars is expected to exceed 30m and cannot be hoisted at one time. During hoisting, a single steel bar is still a semi-finished product, and the total length is generally within 18m. Only one crane is used for lifting at two points. The hoisting process is the same as above, but a platform truck is required to splice the two steel bars at high altitude.

[0006] Based on the above reasons, a steel rod construction platform vehicle is needed, which can carry out mechanized installation of steel rods simultaneously during the layered mechanical excavation of the factory building. After the excavation and preliminary support of each layer are completed, mechanical drilling is carried out according to the angle classification, and the angle of the steel rod installation track is adjusted synchronously to carry out the steel rod installation work without affecting the continued excavation work of the machinery in other areas, so as to achieve the construction appearance of layered excavation and process-based assembly lines, and achieve the purpose of shortening the linear construction period. Summary of the invention

[0007] The technical problem solved by the present invention is to provide a movable mechanized construction platform vehicle for steel bars in underground factories. The prior art cannot complete the integrated operations of steel bar transportation, on-site processing and assembly, steel bar lifting, and angled positioning installation during the mechanical excavation of factories, and cannot ensure that the conditions for simultaneous mechanical construction of steel bars are available during the mechanical excavation, resulting in a long construction period.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: a movable underground workshop steel bar mechanized construction platform vehicle, comprising a mobile platform vehicle, an angle adjustment device and a crane are provided on the mobile platform vehicle along the length direction of the mobile platform vehicle, and a steel bar installation track is also provided on the angle adjustment device;

[0009] The angle adjustment device comprises a first supporting steel tube, a second supporting steel tube and a third supporting steel tube arranged along the length direction of the mobile platform vehicle, and the bottom ends of the first supporting steel tube, the second supporting steel tube and the third supporting steel tube are fixed to the mobile platform vehicle through a connecting bottom plate; the top ends of the first supporting steel tube and the second supporting steel tube are provided with bearing connecting plates, and track connecting plates are fixed to the bearing connecting plates, and the two track connecting plates are located on the same side of the wheel axle, and the track connecting plates are fixedly connected to the steel rod mounting track through a track connecting base; two vertical threaded rods are also provided on the bearing connecting plate at the top of the first supporting steel tube, and the threaded rods are respectively located on the left and right sides of the rotating shaft of the wheel axle after passing through the base plate of the wheel axle, and an adjusting nut that is tight against the base plate is sleeved on the threaded rod under the base plate of the wheel axle; a crane connecting plate is provided on the top of the third supporting steel tube, and the crane wheel axle and the crane are connected in sequence above the crane connecting plate;

[0010] The steel rod installation track includes a U-shaped bottom groove arranged on the track connection base, a plurality of rolling shafts are arranged in the U-shaped bottom groove along the length direction, and also includes a pull rope wound around the outside of the rolling shaft, and a steel rod bearing sleeve is fixedly installed on the pull rope; a motor mounting seat is also provided on the outer wall of one end of the U-shaped bottom groove, and a rotating motor is provided on the motor mounting seat, and the rotating motor drives the pull rope and the steel rod bearing sleeve to rotate around the rolling shaft.

[0011] In particular, a cushion layer is also provided on the bearing connecting plate at the top of the second supporting steel pipe.

[0012] Particularly, a plurality of limiting clips are provided at the top opening of the U-shaped bottom groove along the length direction.

[0013] Particularly, an aiming and placing rod for aligning the steel rod installation position is provided at one end of the U-shaped bottom groove away from the motor mounting seat.

[0014] Furthermore, the aiming and releasing rod includes an L-shaped aiming rod respectively arranged on the left and right side walls of the U-shaped bottom groove, the L-shaped aiming rod is arranged back to back, and a downwardly inclined guide plate is provided at the end of the U-shaped bottom groove.

[0015] Particularly, a steel bar storage platform is also provided on the mobile platform vehicle.

[0016] In particular, the mobile platform vehicle is also provided with anti-collision guardrails and handrails on the outside.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. Multiple processes on the plane and mechanized coordination. The finished steel bars are transported by mobile platform vehicles, and the finished product protection, pre-installation processing, and on-site steel bar rectification and repair work are conveniently carried out on the operating table. On the mechanized excavation workshop working surface, the uncivilized stacking of materials is reduced, the interference with other operating machinery is reduced, and the limited construction space is fully planned and utilized to the greatest extent.

[0019] 2. Save installation time. The one-time carrying capacity meets the construction volume, saving the time of multiple transportations; the convenient steel bar track installation saves manual adjustment time; most of the processes can be completed on the platform car, saving the time of process connection; the deflection deformation caused by hoisting is not included, the installation angle is more accurate, saving the time of defect rectification.

[0020] 3. It is conducive to safe and civilized construction. The steel bar platform car can carry and install the steel bar in the hole, and there is no uncivilized stacking of materials; mechanization replaces part of the manual operation, reduces the work of on-site personnel, and is conducive to reducing safety hazards.

[0021] 4. The cost-effectiveness of the investment and benefit output is high. Calculated based on the number of more than 300 steel bars, the investment cost is about 1 / 6 of the cost saved by shortening the construction period, which has a high economic benefit.

[0033] In the present invention, first, each accessory is cut off-site according to the processing size. The accessories are selected to assemble the steel rod installation track 4, and the rolling shaft 42 is welded between the left and right side walls of the U-shaped bottom groove 41 at a spacing of 30 cm. The pulley group of the pull rope 43 is fixedly installed at the front and rear ends of the U-shaped bottom groove 41, and a motor mounting seat 45 is set at one end of the U-shaped bottom groove 41. A rotating motor 46 is fixed on the motor mounting seat 45, and the pull rope 43 is driven to move around the outside of the rolling shaft 42 by the rotating motor 46. At the same time, a steel rod bearing sleeve 44 is fixedly installed on the pull rope 43. In the process of the rotating motor 46 driving the pull rope to rotate, the steel rod bearing sleeve 44 drives the steel rod to move on the rolling shaft 42, thereby realizing the transportation and movement of the steel rod. During the transportation and movement of the steel bar, since the installation of the steel bar usually has an inclination angle, the angle range is usually -5°~30°. When the front end of the steel bar installation track 4 sinks, a plurality of steel bar bearing sleeves 44 are usually set on the pull rope 43 according to the length of the steel bar, and the steel bar is placed between two steel bar bearing sleeves 44, so that the steel bar is pushed forward by the steel bar bearing sleeve 44 at the rear end, and the steel bar bearing sleeve 44 at the front end provides a supporting force to prevent the steel bar from sliding. When the front end of the steel bar installation track 4 rises, the steel bar can be driven and supported only by the steel bar bearing sleeve 44 at the rear end of the steel bar.

[0034] like Figure 5 As shown, continue to assemble the angle adjustment device 2 off-site, weld the bearing connecting plate 25 and the connecting bottom plate 24 to the two ends of the supporting steel pipe, dig a through hole on the base plate 261 of the wheel axle 26, insert the threaded rod 251, rotate the adjusting nut 252 to adjust the wheel axle 26 to a normal height, and then set the track connecting plate 27 on the end of the rotating shaft of the wheel axle 26, and weld the track connecting base 28 on the outer wall of the track connecting plate 27.

[0036] Finally, the mobile platform vehicle 1 is processed and connected to the above three systems. First, holes are drilled in the bottom steel plate and then the mobile wheels are welded. Then, the angle adjustment device 2, the hoisting system and the steel bar installation track 4 are connected in sequence with nuts. The short side wall of the welded track connection base 28 is used to limit the movement of the track. The connecting plate of the track on the other side does not need to be welded, which is used to provide the displacement after adjusting the angle. Then, an I-beam support is welded on one side of the mobile platform vehicle 1, and a steel bar storage platform 11 and a storage platform guardrail are set on the I-beam support.
