Abstract
Description
Technical Field
[0001] This utility model relates to the field of film covering auxiliary equipment technology, and in particular to an adjustable rapid film covering tool for building construction sites. Background Technology
[0002] In the fields of civil engineering building structure maintenance and landscaping plant maintenance, the structures and plants requiring maintenance are generally in the early stages of construction or planting, before the concrete or mortar has set and the plants have just been planted. Temperature, humidity, and other conditions need to be controlled. Therefore, a thin film, typically a homogeneous plastic film, is needed to cover their surfaces.
[0003] In existing film covering processes, two workers are often required to work simultaneously. The specific process involves two workers each dragging one end of a film roller and moving along the ground where the film needs to be covered, rotating the film roller as they move to unfold the film and cover the ground.
[0004] However, the entire lamination process involves manual movement, with the film rollers being dragged along, which significantly increases the workload for workers. Furthermore, ensuring the film rollers are at the same height at both ends is crucial for a smooth finish, which is difficult to achieve manually. If mechanical support is used, the unevenness of the film rollers on different sides of the surface during lamination can also occur on some sites.
[0005] Therefore, there is an urgent need in this field for an adjustable, rapid film covering tool for construction sites to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide an adjustable quick film covering tool for construction sites to solve the problems existing in the prior art, reduce the labor intensity of workers covering films, and keep the two ends of the film roller at the same height.

A height adjustment block is connected inside the height adjustment groove, and the lower end of the height adjustment block can be inserted into the height adjustment groove. The height adjustment block can move up and down in the height adjustment groove. A positioning device is connected to the height adjustment groove to fix the height adjustment block. The height adjustment block is provided with a roller shaft connection hole, and both ends of a film roller can be rotatably connected to the roller shaft connection holes on the two height adjustment blocks respectively.
[0009] Preferably, the positioning device is a positioning bolt, and the side wall of the height adjustment groove is provided with a positioning threaded hole.

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The purpose of this invention is to provide an adjustable quick film covering tool for construction sites to solve the problems existing in the prior art, reduce the labor intensity of workers covering films, and keep the two ends of the film roller at the same height.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] like Figures 1-2As shown, this embodiment provides an adjustable rapid film covering tool for construction sites, including two film covering supports 1, which are located on opposite sides of the film covering surface during film covering operations. A walking device 2 is provided at the lower end of each film covering support 1, allowing the support 1 to move. A height adjustment groove is provided in the upper rectangular block of each film covering support 1, and a height adjustment block 3 is connected within this groove. The lower end of the height adjustment block 3 can be inserted into the groove, and it can move up and down within the groove. A positioning device 4 is connected to the groove, fixing the height adjustment block 3 in place, preventing it from moving up and down within the groove. Each height adjustment block 3 has a roller connection hole, and both ends of a film roller (i.e., the roller portions at both ends) can be rotatably connected to these holes on the two height adjustment blocks 3, allowing the film to be unfolded or retracted when the film roller rotates.
[0029] When lamination is required, first install both ends of the film roller containing the film into the roller connection holes on the two height adjustment blocks 3. The two lamination supports 1 can then be moved from one end of the lamination surface to the other. It is important to note that during the lamination process, the starting end of the film should ideally be pressed down by a worker or supported by a weight to prevent movement of the film's starting end during the movement of the lamination supports 1, which could cause the subsequent film to shift. As the lamination supports 1 move, the starting end of the film is pressed down, causing the film roller to rotate under the tension of the film's starting end, thus gradually unfolding the film on the film roller and achieving lamination.
[0030] When the film needs to be recycled, simply drive the film support 1 to move in one direction. During the movement, drive the film roller to rotate in the opposite direction, thereby winding up the film.
[0031] In this embodiment, the positioning device 4 has two structures, as detailed below:
[0032] Firstly, the positioning device 4 is a positioning bolt. The side wall of the height adjustment groove is provided with a positioning threaded hole, and the positioning bolt is threaded into the positioning threaded hole. Furthermore, the end of the positioning bolt that is tightened into the positioning threaded hole abuts against the height adjustment block 3, thereby fixing the height adjustment block 3 and preventing it from moving up and down.
[0033] Secondly, the positioning device 4 is a positioning pin. A first positioning pin hole is provided on the side wall of the height adjustment groove, and multiple second positioning pin holes are provided on the height adjustment block 3, with these second positioning pin holes spaced apart from top to bottom. In actual use, the positioning pin can pass through one first positioning pin hole and one second positioning pin hole in sequence, thereby restricting the vertical movement of the height adjustment block 3. Furthermore, when the positioning pin passes through different second positioning pin holes, the height adjustment block 3 corresponds to different heights.
[0034] In the actual manufacturing process, the positioning device 4 can be any one of the two methods mentioned above, and of course it is not limited to the two methods mentioned above. Any device that can fix the height adjustment block 3 at the required positioning height is acceptable.
[0035] In this embodiment, the film-coated support 1 is a triangular frame, which has the characteristics of simple structure, low manufacturing cost and high stability.
[0036] In this embodiment, the film-coating support 1 is connected to a push-pull rod 6, which is a T-shaped rod. Workers can use the push-pull rod 6 to move the film-coating support 1. The advantage of providing the push-pull rod 6 is that it facilitates the application of pushing and pulling force by workers.
[0037] In this embodiment, the film roller has connecting through holes at both ends, and the connecting through holes are connected to drive shafts. Specifically, the cross-section of the connecting through hole is rectangular, and the cross-section of the end of the drive shaft connected to the connecting through hole is also rectangular, with the same cross-sectional dimensions as the connecting through hole, allowing them to rotate synchronously. A rotating device is connected to the end of the drive shaft away from the connecting through hole. Furthermore, the cross-sectional shape of the drive shaft away from the connecting through hole is circular, which is designed to facilitate connection with the rotating device. It should be noted that, generally, the rotating device is only activated when recycling the film. The rotating device and the drive shaft drive the film roller to rotate, thereby performing the film winding operation. During the lamination process, with the movement of the lamination support 1 and the fixing of the film's starting end, no other external force needs to be applied to the film roller; the film roller can rotate due to the force of the film itself.
[0038] In this embodiment, the rotating device also comes in two forms, as follows:
[0039] Firstly, the rotating device is a rotating handle. When the rotating device is a rotating handle, the rotating handle can be manufactured as an integral part of the drive shaft. This structure is simple, so the manufacturing cost is low.
[0040] Secondly, the rotating device is a rotary motor, which can be an existing non-self-locking motor (the rotary motor will not interfere during the lamination process). The output shaft of the rotary motor is connected to the transmission shaft via a coupling or other means, and the rotary motor is mounted on the lamination support 1. When the rotary motor is started, it can drive the film roller to rotate via the transmission shaft, thereby winding up the film.
[0041] In addition, when the rotating device is a rotating motor, a control device must be installed. The rotating motor is electrically connected to the control device to control the switching of the rotating motor. The control device can be an existing PLC controller or a single-chip microcomputer controller, and it can be installed on the push-pull rod 6 for easy operation by the staff.
[0042] In this embodiment, after the film has been covering the film for a period of time, some impurities will inevitably adhere to it. During recycling, these impurities may contaminate or even tear the film. Therefore, this embodiment includes a scraper 5 connected between the two height adjustment blocks 3. During the film winding process, the film will come into contact with the scraper 5, which is used to scrape off the impurities on the film. Regarding the fixing method of the scraper 5, it can be integrally manufactured with the height adjustment block 3, or the scraper 5 can be fixed to the height adjustment block 3 by bolts.
[0043] In this embodiment, the scraper 5 is a scraper, and the end of the scraper is provided with a scraper strip. The scraper strip can be made of polypropylene or rubber to avoid scratching the plastic film.
[0044] In this embodiment, the walking device 2 is a non-powered omnidirectional wheel, specifically equipped with four omnidirectional wheels, which are respectively located at the four lower corners of the laminating bracket 1. This method has low manufacturing costs. Alternatively, the walking device 2 can also use existing electric wheels, with one electric wheel located at each of the four lower corners of the laminating bracket 1. The axle of at least one electric wheel is connected to the output shaft of a drive motor to drive the electric wheel to rotate. Using electric wheels for walking can reduce the labor intensity of workers. Furthermore, the drive motor of the electric wheel is also electrically connected to a control device, making it convenient for workers to control its on / off state.
[0045] In this embodiment, a bearing is provided in the roller shaft connection hole, wherein the outer ring of the bearing is connected to the inner wall of the roller shaft connection hole, and the end of the film roller is connected to the inner ring of the bearing. The purpose of providing the bearing is to effectively reduce the friction between the film roller and the roller shaft connection hole, thereby extending the service life of the height adjustment block 3 and the film roller.
