Description

Technical Field

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

[0002] At present, prefabricated subway stations are an innovative application of prefabricated buildings in the field of subway construction. It transforms the construction method of traditional cast-in-place structure subway stations into factory prefabrication and on-site assembly, thus realizing the rapid, efficient and green construction of subway stations. Prefabricated subway stations prefabricate the main structure of subway stations (such as floor, side walls, vaults, etc.) in the factory and then transport them to the construction site for assembly. They have many advantages: ① Improve construction efficiency. The construction speed of prefabricated stations is much faster than that of traditional cast-in-place stations. The comprehensive construction period can be shortened by 4 to 6 months, which is conducive to speeding up the progress of urban rail transit construction. ② Save materials. Prefabricated components are produced in the factory, which can accurately control the amount of materials and reduce waste. At the same time, there is no need to adopt large-scale warming measures during the construction of prefabricated stations, which further saves material costs. ③ Reduce environmental impact: There is no on-site template erection, steel bar binding and welding, concrete pouring and vibration during the construction process of prefabricated stations, which effectively reduces the pollution of construction noise and dust to the surrounding environment.

[0003] Furthermore, prefabricated subway stations also have the following characteristics: prefabricated components are heavy and require high assembly precision. During the assembly process, the gap between components is relatively high. Station assembly is dry joints (i.e., two prefabricated parts are butt-jointed), and there are fewer wet joints (i.e., joints cast after assembly), so it is easy to produce installation errors during the assembly process.

[0004] In the related art, the assembly equipment of the traditional prefabricated station is an integral type, and the integral type assembly equipment requires auxiliary assembly such as Figure 1 The bottom plate 101, bottom longitudinal beam 102, column 103, middle longitudinal beam 104, side wall 105, middle plate 106, top longitudinal beam 107 and top plate 108 of the prefabricated station shown in the figure have an integral assembly equipment which is extremely large, heavy and cumbersome, has a slow moving speed, is not flexible enough in movement or coordination between different structures to be assembled, and cannot effectively eliminate the installation errors between various dry joints.

[0066] Specifically, the column assembly machine 1, the side wall assembly mechanism 21, and the top longitudinal beam adjustment mechanism 32 are all working with the door crane when assembling their respective structures to be assembled. The load bearing is borne by the door crane, and the position adjustment is performed by each assembly machine.

[0093] Specifically, when the two third transverse cylinders 214 perform differential operation, they can drive the side wall to rotate at a small angle.

[0094] The assembly equipment of the present application can drive the side wall 105 to move horizontally, vertically and rotate through two third transverse movement cylinders 214 and one third longitudinal movement cylinder 216, thereby providing a basis for high-precision assembly and effectively eliminating installation errors of the side wall 105.

[0095] like Figure 7 As shown, in one embodiment, the top longitudinal beam assembling machine 3 includes a top longitudinal beam adjusting mechanism 32 , and the top longitudinal beam adjusting mechanism 32 includes a horizontally arranged fixing seat 321 .

[0096] The fixed seat 321 is provided with a transverse sliding sleeve 322 and a fourth transverse oil cylinder 326 providing power for the transverse sliding sleeve 322. Specifically, one end of the fourth transverse oil cylinder 326 is fixed to the fixed seat 321, and the other end is fixed to the transverse sliding sleeve 322. The fourth transverse oil cylinder 326 pushes the transverse sliding sleeve 322 to move transversely.

[0097] A longitudinal sliding sleeve 327 and a fourth longitudinal oil cylinder 323 providing power for the longitudinal sliding sleeve 327 are arranged in the transverse sliding sleeve 322; specifically, one end of the fourth longitudinal oil cylinder 323 is fixed to the transverse sliding sleeve 322, and the other end is fixed to the longitudinal sliding sleeve 327. The fourth longitudinal oil cylinder 323 pushes the longitudinal sliding sleeve 327 to slide longitudinally.

[0098] A vertical moving bracket is vertically arranged on the longitudinal moving sleeve 327, and a vertical sliding sleeve 328 and a lifting cylinder 329 providing power to the vertical sliding sleeve 328 are arranged on the vertical moving bracket. Specifically, one end of the lifting cylinder 329 is fixed to the longitudinal moving sleeve 327, and the other end is fixed to the vertical sliding sleeve 328. The lifting cylinder 329 pushes the vertical sliding sleeve 328 to slide up and down.

[0099] The vertical moving bracket is provided with a clamping mechanism 324 for clamping the top longitudinal beam 107 , and a clamping cylinder 325 for providing power to the clamping mechanism 324 .

[0100] During actual assembly, two top and longitudinal beam assembling machines 3 are usually used simultaneously, and two top and longitudinal beam adjustment mechanisms 32 clamp the top and longitudinal beams front and back in the longitudinal direction, and drive the top and longitudinal beams to move horizontally, longitudinally, vertically and rotate.

[0101] In the assembly equipment of the present application, the top and longitudinal beam adjustment mechanism 32 can drive the top and longitudinal beams to move horizontally, longitudinally, vertically and rotate, further maintaining the high-precision assembly of each top and longitudinal beam and eliminating installation errors.

[0102] On the second aspect, the present application also discloses a construction method of assembly equipment based on prefabricated stations. Specifically, the assembly process of the prefabricated station is: bottom plate → bottom longitudinal beam → column → middle longitudinal beam → side wall → middle plate → top longitudinal beam → top plate.

[0103] The assembly methods of the structures to be assembled are shown in Table 1:

[0104] Table 1

[0105]

[0106]

[0107] The construction method of the assembling equipment of the present application is characterized by comprising the following steps:

[0108] S1: Laying the bottom plate 101, and laying the bottom longitudinal beam 102 on the bottom plate 101, and setting a reserved groove on the bottom longitudinal beam 102;

[0109] S2: Use the door crane and the column assembly machine 1 to install the column 103, insert the column 103 into the reserved groove of the bottom longitudinal beam 102 and adjust the position; the middle part of the column 103 has a lateral protrusion;

[0110] S3: Install a middle longitudinal beam 104 between the side protrusions of two adjacent columns 103;

[0111] S4: Use the door crane and the side wall middle plate assembly machine 2 to first install the side wall 105, and then set up the middle plate 106 on the protrusion of the side wall 105 and the middle longitudinal beam 104; clamp the two side wall middle plate assembly machines 2;

[0112] S5: Use the gantry crane and the top longitudinal beam adjustment mechanism 32 of the top longitudinal beam assembling machine 3 to cooperate in installing the top longitudinal beam, and use the traveling platform 33 of the top longitudinal beam assembling machine 3 to assist in installing the top plate 108.

[0113] In one embodiment, the clamping mechanism 14 includes two clamping devices spaced apart from each other. In step S2, the column 103 is inserted into the reserved groove of the bottom longitudinal beam 102 and aligned, including:

[0114] After the door crane lowers the column 103 to a certain distance from the reserved groove of the bottom longitudinal beam 102, the clamping device at the bottom is used to cooperate with the door crane to clamp the column 103 and move the column 103 horizontally, vertically and rotationally to the reserved groove of the bottom longitudinal beam 102;

[0115] After the alignment and assembly is completed, the clamping device at the bottom is used to clamp the column 103 and adjust the verticality of the column 103 when the alignment of the column 103 is completed and the clamping device at the bottom is released.

[0116] The construction method of the present application uses two clamping devices arranged at intervals above and below to first move the column 103 horizontally, vertically and rotationally to complete the alignment, and then clamp the column 103 and adjust the verticality of the column 103 to perform a refined division of labor, which can complete the assembly work with high precision and eliminate the error in the assembly step of the column 103.

[0117] In one embodiment, the top longitudinal beam assembly machine 3 includes a top longitudinal beam adjustment mechanism 32, which includes a horizontally arranged fixed seat 321, the fixed seat 321 is sleeved with a transverse sliding sleeve 322, and a fourth transverse oil cylinder 326 providing power for the transverse sliding sleeve 322; a longitudinal sliding sleeve 327 is arranged in the transverse sliding sleeve 322, and a fourth longitudinal oil cylinder 323 providing power for the longitudinal sliding sleeve 327;

[0118] A vertical moving bracket is vertically arranged on the longitudinal moving sleeve 327, a vertical sliding sleeve 328 and a lifting cylinder 329 for providing power to the vertical sliding sleeve 328 are arranged on the vertical moving bracket; a clamping mechanism 324 for clamping the top longitudinal beam 107 and a clamping cylinder 325 for providing power to the clamping mechanism 324 are arranged on the vertical moving bracket;

[0119] In step S5, the top longitudinal beam is installed by using the door crane and the top longitudinal beam adjustment mechanism 32 of the top longitudinal beam assembly machine 3, including:

[0120] After the gantry crane lowers the top longitudinal beam 107 to a certain distance from the assembly position, the clamping mechanisms 324 of the two top longitudinal beam assembling machines 3 clamp the two sides of the top longitudinal beam 107 through the clamping cylinders 325;

[0121] The lateral, longitudinal and vertical positions of the top longitudinal beam 107 are adjusted by the fourth transverse oil cylinder 326, the fourth longitudinal oil cylinder 323 and the lifting oil cylinder 329, so that the hole position of the top longitudinal beam 107 is aligned with the top of the column 103;

[0122] The door crane falls and the top longitudinal beam 107 is installed in place.

[0123] Specifically, during the actual installation, because the top longitudinal beam is relatively long, with a single beam of 16m, two assembly machines are needed to adjust the top longitudinal beam. The two upper top longitudinal beam assembly machines operate simultaneously. The assembly machine can assemble and fine-tune the top longitudinal beam and provide a platform for the tensioning of the top plate 108.

[0124] In the installation method of the present application, the top and longitudinal beam adjustment mechanism 32 can drive the top and longitudinal beams to move horizontally, longitudinally, vertically and rotate, further maintaining the high-precision assembly of each top and longitudinal beam and eliminating installation errors.

[0125] Further, the process of the middle plate assembly mechanism:

[0126] The middle plate assembly mechanism 23 rises and receives the middle plate 106;

[0127] The whole machine is moved longitudinally to the assembly position for fine adjustment of the middle plate, which includes horizontal movement, longitudinal movement and optional installation;

[0128] After adjustment, the lifting platform moves down the middle plate to complete the assembly;

[0129] Among them, the left and right assembly machines need to cooperate to assemble the middle plate. There are two types of middle plates, one is integral and the other is split. When assembling the integral middle plate, the two assembly machines need to cooperate with each other, and when assembling the split middle plate, the left and right assembly machines need to assemble separately.

[0130] Further, the process of the side wall assembly mechanism:

[0131] Place the side wall at the assembly position, and the connecting mechanism connects the side wall adjustment mechanism to the side wall;

[0132] After the connection is completed, the verticality of the side wall can be adjusted through the longitudinal movement mechanism and the oil cylinder of the connecting mechanism.
