Description

Technical Field

[0001] The invention belongs to the technical field of piers, and in particular relates to a device for film covering of concrete piers. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Concrete piers are a kind of component commonly used in various road and bridge constructions. They use a large amount of concrete to cast into the shape of a column. Due to the physical properties of concrete, it requires a long construction period and certain subsequent maintenance to take shape. At present, the most commonly used maintenance method is drip irrigation film maintenance. After demolding, a layer of film is coated on the surface of the pier. The film coating operation is generally performed manually. Generally, the operator stands in the bucket to operate, and the bucket will swing back and forth in the air, resulting in unqualified quality of the covering film, or an operating platform is set along the height direction of the pier. During the construction process, the personnel carry out construction in a fixed construction direction (generally from top to bottom). The inventor believes that the manual film coating operation is obviously unsafe, and the efficiency cannot be guaranteed to be too low.

[0004] However, the devices for coating disclosed in the prior art require different types of equipment to coat concrete piers of different heights, which is not convenient to use. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a device for covering concrete piers with film, which solves the problem that the existing devices for covering concrete piers with film are inconvenient for people to use. Concrete piers of different heights can be covered with film without the need to use different types of equipment, thereby reducing the cost of use. When covering the concrete piers, the film can be tightly wrapped without affecting the quality of the covering.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] The technical solution of the present invention provides a device for covering concrete piers with film, comprising a box, an annular shell and an annular ring, the annular shell is used to accommodate the concrete pier, the annular shell is also coaxially connected with the annular ring, and the box is connected to the annular ring; a transmission mechanism is provided between the box and the annular ring, and a power source connected to the transmission mechanism is provided in the box to drive the box to rotate along the annular ring around the concrete pier; the side of the box close to the concrete pier is also connected to a film pulling shaft for pulling the film.

[0008] When the present invention is used for coating, the device is first assembled with the lifting device, and then the annular shell is lifted and sleeved on the surface of the concrete pier main body, the annular shell is lowered to the bottom of the concrete pier main body, and then the film roll is sleeved on the film-pulling shaft, and then the shielding plate is fixed on the film-pulling shaft, and the film roll is connected to the concrete pier main body, and then the speed of the stepper motor is set by the external controller and the motor speed regulator, and the stepper motor is driven by the external controller. The stepper motor drives the rotating shaft to start rotating through the bearing seat, and the rotating shaft drives the gear to start rotating. The gear rotates in the annular ring through the teeth, so that it drives the box to rotate, and at the same time, the box drives the slider to slide in the annular slide groove through the groove, and then drives the film roll to wrap the surface of the concrete pier main body through the support plate, the fixed plate, the cross roller bearing and the film-pulling shaft. While the film is being wrapped, the annular shell is lifted upward by the external lifting device, so that it can coat the entire concrete pier main body.

[0009] The beneficial effects of the technical solution of the present invention are as follows:

[0010] 1) The present invention solves the problem that the existing film covering device for concrete piers is inconvenient for people to use. Automatic film covering can be achieved by driving with a power source, and concrete piers of different heights can be covered without using different types of equipment, thereby reducing the use cost. When covering the concrete pier, the film can be tightly wound without affecting the quality of the film covering.

[0011] 2) In the present invention, by setting a bearing seat, the rotation of the rotating shaft is stabilized when in use, which solves the problem of shaking of the rotating shaft when in use; by setting a mounting plate, the stepper motor is fixed and stabilized when in use, which solves the problem of falling off of the stepper motor when in use; by setting an annular groove and a slider, the sliding of the groove and the box body is stabilized when in use, which solves the problem of unstable sliding of the groove and the box body when in use.
