Description

Technical Field

[0001] The invention relates to concrete column maintenance, in particular to a winding device for covering a concrete column maintenance film. Background Art

[0002] Concrete column maintenance is the sub-project that takes the longest time and has the greatest impact on concrete quality in the entire concrete construction. The main maintenance method currently used on construction sites is natural curing. This maintenance method requires measures such as watering and spraying to ensure that the concrete is moist. However, for vertical components such as structural columns, watering maintenance is difficult and it is easy to have inadequate maintenance. For this reason, it is necessary to wrap the column components with a film to maintain the temperature and humidity of the components. Traditional methods are mostly manual winding, which is labor-intensive. If the height of the concrete column is too high, winding and covering also involves high-altitude operations, which is not conducive to construction safety.

Specific embodiments

[0025] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0026] See Figures 1 - 3 , this embodiment is a winding device for covering and curing concrete columns, mainly composed of a base 1, a column 2, a lifting mechanism, and a winding mechanism. The base 1 is rectangular, and four wheels 1-1 are installed at its bottom. A T-shaped pull rod 1-2 is hinged and installed at the right end of the base 1.

[0027] A vertical column 2 is installed at the left end of the upper part of the base 1. Its material is channel steel, and its opening faces the left end of the base 1. A lifting mechanism is installed on the column 2. The lifting mechanism is mainly composed of a lead screw 2-2, a lead screw nut, a motor 3, a reducer 3-1, a guide rail 4, and a slider (not shown in the figure). The lead screw 2-2 is vertically placed in the notch of the column 2. The two ends of the lead screw 2-2 are respectively connected to the web of the column 2 through bearing seats 2-3. The top of the column 2 is installed with a top plate 2-1. A notch is opened at the lower end of the web of the column 2, which is used to accommodate the reducer 3-1. The output shaft of the reducer 3-1 is vertically arranged and located in the notch of the column 2. The output shaft of the reducer 3-1 is connected to the lower end of the lead screw 2-2 through a coupling. The reducer 3-1 is bolted to the base 1 and is driven by the motor 3 installed on it. The motor 3 is located on the right side of the column 2. Guide rails 4 are respectively installed at the outer ends of the two flange plates of the column 2. A slider is slidably connected to each guide rail 4. A connecting plate 5 is installed between the two sliders. The inner plate surface of the connecting plate 5 is fixedly connected to the lead screw nut on the lead screw 2-2. An equipment control box 11 is installed on the base 1 inside the column 2. The motor 3 and the reducer 3-1 can also be installed on the top plate 2-1. The output shaft of the reducer 3-1 passes through the top plate 2-1 and is connected to the upper end of the lead screw 2-2 through a coupling.

[0028] The outer plate surface of the connecting plate 5 is equipped with a winding mechanism, which mainly consists of a rotating bracket 6, a rotating ring 7, a driving component 8, and a film covering and fixing component 9. The rotating bracket 6 mainly consists of a fixed seat 6-1 and two track brackets 6-2. The fixed seat 6-1 is a rectangular block, which is connected or welded to the connecting plate 5 by bolts. The two track brackets 6-2 are symmetrically arranged on both sides of the fixed seat 6-1. The track brackets 6-2 are obtuse-angled. Their inner ends are connected to the two side surfaces of the fixed seat 6-1 by bolts. The fixed seat 6-1 and the two track brackets 6-2 are in a C shape. The inner side surface of the track bracket 6-2 is provided with a track groove 6-3, and the cross-section of the track groove 6-3 is in an E shape.

[0029] The rotating ring 7 is placed inside the rotating bracket 6. The rotating ring 7 is circular. The cross-section of its outer circumferential surface is concave, and its concave side is placed. The rotating ring 7 is slidably connected to the track grooves 6-3 of the two track brackets 6-2. The rotating ring 7 rotates in the track grooves 6-3. The arc length of the rotating ring 7 inside the rotating bracket 6 is greater than the arc length of the rotating ring 7 outside the rotating bracket 6, ensuring that the rotating ring 7 does not disengage from the rotating bracket 6. A gear ring 7-1 is installed inside the concave of the rotating ring 7. The gear ring 7-1 is a split structure and is connected to the rotating ring 7 by bolts.

[0030] The rotating ring 7 is driven by the driving component 8. The driving component 8 mainly consists of a driving motor 8-1 and a driving gear 8-2. The axis of the driving motor 8-1 is vertically arranged, and its output shaft is downward. It is installed on the outer plate surface of the connecting plate 5. The output shaft of the driving motor 8-1 is installed with the driving gear 8-2. The driving gear 8-2 is disc-shaped and meshes with the gear ring 7-1 of the rotating ring 7 for transmission.

[0031] A film covering and fixing component 9 is installed inside the rotating ring 7. The film covering and fixing component 9 mainly consists of a film covering frame 9-1, a fixing plate 9-2, and a fixing shaft 9-3. The film covering frame 9-1 is U-shaped, and its opening side is placed. The vertical part of the film covering frame 9-1 is connected to the inner circumferential surface of the rotating ring 7 through the fixing plate 9-2. The thickness of the fixing plate 9-2 ensures that the film covering frame 9-1 does not interfere with the track bracket 6-2 when rotating with the rotating ring 7. Long grooves are symmetrically opened at the outer ends of the two horizontal parts of the film covering frame 9-1. The film roll 12 is placed between the two horizontal parts. The two ends of the fixing shaft 9-3 pass through the hollow reel of the film roll 12 and the long grooves, and the two ends of the fixing shaft 9-3 are connected to the long grooves by wing nuts.

[0032] A guiding roller assembly 10 is installed between the two horizontal parts of the film covering frame 9-1. The guiding roller assembly 10 is located outside the film roll 12. The guiding roller assembly 10 mainly consists of a first guiding roller 10-1 and a second guiding roller 10-2. The first guiding roller 10-1 and the second guiding roller 10-2 are arranged adjacent to each other. The roller shafts of the two guiding rollers are respectively connected to the two horizontal parts of the film covering frame 9-1. The film is led out from the gap between the first guiding roller 10-1 and the second guiding roller 10-2.

[0033] The working process of this embodiment is as follows: Install the film covering roll 12 into the film covering frame 9-1. Draw out a section of the film covering from the gap between the first guiding roller 10-1 and the second guiding roller 10-2. Start the reduction motor 3. The lifting mechanism drives the winding mechanism to rise. After the winding mechanism is higher than the top of the concrete column, move the entire device so that the rotating ring 7 is sleeved on the concrete column. At this time, workers are required to cooperate on the ground and fix the head of the film covering with a long rod. Start the driving motor 8-1, and the driving gear 8-2 drives the gear ring 7-1 and the rotating ring 7 to rotate in a circular motion. When the film covering frame 9-1 drives the film covering roll 12 to rotate around the concrete column and the film covering is wound around the concrete column, after winding several circles and fixing the head of the film covering, the worker removes the long rod. During the rotation process, the lifting mechanism descends, and the winding of the film covering from the top to the bottom of the column is completed.

[0034] The above are only the preferred and feasible embodiments of the present invention, and do not limit the scope of rights of the present invention accordingly. Any equivalent structural changes made by using the content of the specification and drawings of the present invention are included in the scope of rights of the present invention.
