Abstract
Description
Technical Field
[0001] The utility model belongs to the field of prefabricated component production equipment, and particularly relates to a hoisting type precast component production line. Background Art
[0002] An assembled building refers to a building in which a large amount of on-site operation work in the traditional construction method is transferred to a factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the building construction site, and are assembled and installed on-site through reliable connection methods.
[0003] In traditional precast component production lines, multiple production equipment are involved, such as concrete distributors, vibrating tables, curing kilns, and palletizing machines. Since large equipment such as three-dimensional curing kilns and palletizing machines are involved, the construction cost of the production line is relatively high, the floor area is large, and the energy consumption of the curing kiln is also large. In order to reduce the construction cost and energy consumption of the production line, some customers require that a certain production demand can still be achieved without using three-dimensional curing kilns and palletizing machines. Since large equipment such as three-dimensional curing warehouses and palletizing machines are not involved, the construction cost of the production line will be greatly reduced. At the same time, the form of stacking formworks is used for centralized curing, which can also minimize energy consumption. At the same time, since the palletizing machine is cancelled, a new tool needs to be redesigned to replace the palletizing machine to realize the transfer work of the formwork in and out of the stacking curing station. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a hoisting type precast component production line with low construction cost, low energy consumption, and simple formwork stacking process.

[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined invention purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.
[0020] As shown in the Figures 1-4 attached drawings, the present utility model discloses a hoisting-type precast component production line, which includes a passage 11 in the middle for processing stations arranged around the passage 11. The processing stations include a cleaning / oiling station 100, a mold installation / steel bar installation / embedded part installation station 200, a batching / vibrating station 300, a roughening station 400, a stacking and curing station 500, a mold table placement station 600, and a demolding station 700 arranged in sequence along the processing procedure. The stacking and curing station 500 is located at the end of the passage 11. The cleaning / oiling station 100, the mold installation / steel bar installation / embedded part installation station 200, the batching / vibrating station 300, and the roughening station 400 are located on one side of the passage 11. The mold table placement station 600 and the demolding station 700 are located on the other side of the passage 11. The transportation directions of the mold tables on both sides of the passage 11 are opposite. A hoisting device for transferring the mold tables is provided between the roughening station 400, the mold table placement station 600 and the stacking and curing station 500, which is used to transport the mold tables to the stacking and curing station 500 for curing and transport the mold tables to the mold table placement station 600 after curing. The transfer of the mold tables between other stations is carried out by a transfer ferry car. The production line of the present utility model cancels the three-dimensional curing kiln and the palletizer, greatly reducing the construction cost of the production line. Moreover, since the running directions of the materials on the left and right sides of the passage are opposite, the occupied length of the production line can be effectively reduced. Considering that the stacking and curing station 500 can carry out the curing work of multiple mold tables at one time, three pre-stage stations can be arranged in parallel to improve the production efficiency.
[0021] Preferably, a hoisting station 800 is further provided after the process of the demolding station 700, and a finished product stacking station 900 is provided at the other end of the passage 11.
[0022] In the present utility model, the cleaning / oiling station 100, the mold installation / steel bar installation / embedded part installation station 200, the batching / vibrating station 300, the roughening station 400, the stacking and curing station 500, the mold table placement station 600, the demolding station 700 and the transfer ferry car all adopt existing technologies and will not be elaborated here.
[0023] The hoisting device includes a crane 10 and a lifting appliance installed below the crane 10. The crane 10 is at a high position of the entire production line, spanning the roughening station 400 and the mold table placement station 600, and can realize the transfer of the mold tables between the roughening station 400 and the stacking and curing station 500, and between the stacking and curing station 500 and the mold table placement station 600.
[0024] The lifting device includes a frame 1 and a gripper arm device. A lifting ring 7 is provided on the frame 1 for connecting with an overhead crane, enabling hoisting and movement.
[0025] The gripper arm device includes clamping arms 2, clamping jaws 4 and an oil cylinder 6. The clamping arms 2 are located outside the frame 1, with their upper ends above the frame 1 and their lower ends below the frame 1. An oil cylinder seat 9 is fixedly installed on the top surface of the frame 1. The cylinder body of the oil cylinder 6 is connected to the oil cylinder seat 9 through a rotating shaft, and the piston rod is connected to the upper end of the clamping arm 2 through a rotating shaft. Clamping jaws 4 are provided at the lower ends of the clamping arms 2. The clamping jaws 4 are bent portions provided at the lower ends of the clamping arms 2 and bent inward. A connecting seat 8 is provided on the frame 1. The middle part of the clamping arm 2 is connected to the connecting seat 8 through resistance welding. Driven by the oil cylinder 6, the clamping arm 2 can deflect around the connecting shaft between the connecting seat 8 and the clamping arm 2. The mold table is located inside the four groups of gripper arm devices. When the clamping jaws 4 of the four groups of gripper arm devices deflect inward, the mold table can be gripped tightly, and the overhead crane can hoist and transfer the mold table. When it is transferred to the designated position, the oil cylinder 6 drives the clamping jaws 4 to deflect outward, thus releasing the mold table.
[0026] The gripper arm device of the present utility model grabs the mold table from the side of the mold table, can be connected to an overhead crane at the top of the frame 1, realizes hoisting and transportation, and can stack the mold tables. On some production lines without using a three-dimensional curing kiln and a palletizer, centralized curing can be achieved in the form of stacking the mold tables, minimizing energy consumption to the greatest extent.
[0027] As a further improvement of the present utility model, each clamping arm 2 of the gripper arm device is two arranged in parallel. Cross braces 3 are provided between the upper and lower ends of the two clamping arms 2, and an X-shaped reinforcing bar 5 is provided between the two cross braces 3. The ends of the reinforcing bar 5 are fixedly connected to the two clamping arms 2 respectively. The piston rod of the oil cylinder 6 is connected to the cross brace 3 located above.
[0028] Since the clamping arms 2 are located outside the frame 1, considering the spatial layout, in order to facilitate the connection between the piston rod of the oil cylinder 6 and the cross brace 3, the upper ends of the clamping arms 2 are inclined inward, which can reduce the stroke of the piston rod; and the lower ends of the clamping arms 2 are also inclined inward, which is also convenient for the cooperation between the clamping jaws 4 and the mold table and reduces the stroke of the piston rod.
[0029] As a further improvement of the present utility model, the frame 1 is assembled by splicing left and right. It includes a symmetrical left frame 101 and a right frame 102. After assembling components such as the gripper arm device on the corresponding left and right frames, the left and right frames are fixedly connected together by bolts, which can improve the assembly efficiency.
[0030] The gripper arm device of the present utility model is located on the side of the mold table and grabs the mold table by deflecting the clamping arms. It is convenient to stack the mold tables at the stacking and curing station 500, which can simplify the mold table stacking process and improve the production line efficiency.
