Description

Technical Field

[0001] This utility model relates to the field of precast component casting construction technology, and in particular to a liftable operating platform for concrete casting. Background Technology

[0002] Precast box culvert components are generally produced on an assembly line. After the concrete is placed, construction workers need to check the concrete condition, manually vibrate it, and add more concrete. However, the box culverts used in tunnels are large in size, making it inconvenient for personnel to operate. Therefore, a pouring platform is needed. In the existing technology, the platform is inconvenient to lift, and if the distance between the platform and the mold is not suitable, it will affect the operation of construction workers. In addition, it cannot be used for molds of various specifications, which limits production and use. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Reference Figure 1-3 A lifting operation platform for concrete pouring includes columns 1, flatbed trolley 7 and rails. The columns 1 are provided in at least four sets, usually in even numbers, depending on the scale of concrete precast component pouring. Multiple sets of columns 1 are symmetrically arranged on both sides of the rails. A crossbeam 3 is fixedly connected to the top of the columns 1 to improve the overall connection strength between the columns 1. The flatbed trolley 7 is set on the upper side of the rails. A mold 6 is provided on the upper side of the flatbed trolley 7. The flatbed trolley 7 slides along the rails to move and transport the mold 6.

[0020] The upper side of the mold 6 is equipped with a lifting platform 8, which is convenient for construction personnel to stand and carry out pouring operations. The upper side of the lifting platform 8 is equipped with a guardrail 5 to ensure personnel safety. The lifting platform 8 has a pouring port that is compatible with the mold 6, which is convenient for construction personnel to vibrate and add concrete. The side of the lifting platform 8 is equipped with a protective frame 9 that is compatible with the column 1 to prevent the lifting platform 8 from colliding with the column 1. The column 1 and the lifting platform 8 are close to each other, and the lifting platform 8 slides in contact with the column 1 through the protective frame 9. Guided by the column 1, the lifting platform 8 slides up and down.

[0021] A lifting device 2 is provided on the underside of the crossbeam 3. The lifting device 2 is a hand-operated hoist or an electric hoist. There are at least four sets of lifting devices 2, which are respectively set at the four corners of the lifting platform 8. A steel cable 4 is connected between the lifting device 2 and the protective frame 9 to ensure stable pulling and lifting of the lifting platform 8.

[0022] The protective frame 9 is equipped with an inflatable roller 91 that abuts against the column 1. The inflatable roller 91 is rotatably connected to the protective frame 9. An inflatable tire and a rubber outer tire are provided on the outside of the inflatable roller 91. The rubber outer tire contacts the column 1, and the inflatable tire is located inside the rubber outer tire. The inflatable tire is equipped with an air nozzle. After the inflatable tire is filled with air, it expands and its diameter increases, ensuring that it abuts against the column 1. During the sliding process of the lifting platform 8, the inflatable roller 91 rolls and buffers to avoid collision with the column 1, while increasing the friction and reducing the shaking of the lifting platform 8.

[0023] The protective frame 9 is equipped with an electromagnetic adsorption device, which is embedded inside the protective frame 9. The adsorption surface of the electromagnetic adsorption device is set to correspond to the column 1. After the lifting platform 8 is adjusted in height, it is positioned and fixed by the electromagnetic adsorption device. When the electromagnetic adsorption device is energized, it generates magnetic force to adsorb the column 1, thereby improving the stability of the lifting platform 8.

[0024] In this embodiment, the construction personnel operate the flatbed cart 7 to slide on the track. After reaching the lower side of the lifting platform 8, the flatbed cart 7 stops and the lifting device 2 pulls the steel cable 4 to raise or lower the lifting platform 8. The inflatable roller 91 effectively reduces the impact and restricts the movement of the lifting platform 8. After the lifting platform 8 reaches the appropriate height, the electromagnetic adsorption device is powered on to adsorb the column 1 and fix the lifting platform 8. The construction personnel operate the concrete through the pouring port on the lifting platform 8.

[0025] After the construction is completed, the electromagnetic adsorption device is de-energized, and the lifting device 2 raises the lifting platform 8 to avoid the mold 6, so that the flatbed truck 7 can be moved out.

[0026] Afterwards, the lifting platform 8 is readjusted according to the height of the next mold 6 to facilitate operation by construction personnel.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
