Description

Technical Field

[0001] The utility model relates to the field of civil engineering construction, in particular to a device for scraping concrete from the surface of a template of civil engineering construction. Background Art

[0002] The formwork in civil construction is a temporary supporting structure used to form the required shape and size when pouring concrete until the concrete hardens and can stand on its own. After the concrete reaches sufficient strength, the formwork is carefully removed in a predetermined demolding order. During the removal process, some concrete may remain on the surface of the formwork, and the formwork needs to be scraped off. Existing concrete scraping on the formwork surface is usually done manually or using a scraping device. Since the formwork surface may be uneven, these methods still cannot completely scrape off the remaining concrete, and the scraping effect is poor.

[0003] In view of the above problems, a device for scraping concrete from the surface of a formwork for civil engineering construction is now developed. Utility Model Content

[0004] In order to overcome the disadvantages that the existing concrete scraping on the template surface usually adopts the method of manual removal or using a scraping device, since the template surface may have uneven conditions, these methods still cannot completely scrape away the residual concrete and the scraping effect is poor, the utility model provides a concrete scraping device for the template surface of civil construction.

[0007] Furthermore, the eccentric grinding mechanism includes a hydraulic cylinder, two of the hydraulic cylinders are installed on the mounting frame, the telescopic ends of the hydraulic cylinders are connected to drive motors, and the output shafts of the drive motors are connected to grinders.

[0008] Furthermore, a filtering mechanism is also included, and the filtering mechanism includes a filtering frame, the filtering frame is slidably connected to the mounting frame, a handle is arranged on the front side of the filtering frame, and the lower sides of the left and right parts of the filtering frame are both rotatably connected to a plurality of pulleys.

[0010] Furthermore, six scrapers are arranged at the bottom of the scraping assembly.

DETAILED DESCRIPTION

[0019] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0020] Example 1

[0021] A device for scraping concrete from the template surface of civil engineering construction, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, the rear part of the mounting frame 1 is a curved surface structure, a feeding component 2 is arranged at the front part of the mounting frame 1, a driving component 3 is arranged on the mounting frame 1, and the driving component 3 includes a protective frame, a motor, a transmission roller and a transmission belt, a clamping component 4 is arranged inside the mounting frame 1, and there are 4 clamping components 4, a scraping component 5 is arranged on the mounting frame 1, and the scraping component 5 is located between the clamping components 4, and 6 scrapers are arranged at the bottom of the scraping component 5, a water spray component 6 is also arranged at the front part of the mounting frame 1, a discharging component 7 is arranged at the rear part of the mounting frame 1, and two eccentric grinding mechanisms 8 are arranged on the mounting frame 1, and the eccentric grinding mechanisms 8 are both located between the clamping components 4 and at the rear of the scraping components 5.

[0022] like Figure 1-Figure 3 As shown, the eccentric grinding mechanism 8 includes a hydraulic cylinder 81. Two hydraulic cylinders 81 are installed on the mounting frame 1. The telescopic ends of the hydraulic cylinders 81 are connected to drive motors 82, and the output shafts of the drive motors 82 are connected to grinders 83.

[0023] The formwork in civil construction is a temporary supporting structure, which is used to form the required shape and size when pouring concrete, until the concrete hardens and can stand on its own. After the concrete reaches sufficient strength, the formwork is carefully removed according to the predetermined demoulding sequence. During the removal process, some concrete may remain on the surface of the formwork, and the formwork needs to be scraped off. The operator turns on the device, first the motor output shaft on the driving component 3 drives the transmission belt to move, and then the formwork is transported to the transmission belt through the feeding mechanism, and then the water spray component 6 wets the surface of the formwork to prevent concrete debris from being raised during the scraping and grinding process, and then the pressing component 4 presses the formwork, and as the transmission belt continuously moves the formwork inward, when the formwork is transported to the scraping When the plate is removed, the scraper will initially scrape off the concrete residue on the surface of the template. The six scrapers can remove the residual concrete on the surface of the template more effectively. Since there may be concave blocks or convexities on the surface of the template, there is still concrete residue after being scraped by the scraper. When the template moves to the lower part of the grinder 83, the telescopic end of the hydraulic cylinder 81 drives the drive motor 82 and the grinder 83 to move downward until they contact the template surface. At the same time, the output shaft of the drive motor 82 drives the grinder 83 to move eccentrically, thereby eccentrically grinding and removing the residual concrete on the surface of the template. The grinder 83 can also grind the surface of the uneven template. The clamping components 4 on the front and rear sides can flatten the template to a certain extent, thereby facilitating the secondary use of the template.

[0024] Example 2

[0025] On the basis of Example 1, Figure 1 , Figure 4 and Figure 5 As shown, it also includes a filter mechanism 9, which includes a filter frame 91. The filter frame 91 is slidably connected to the mounting frame 1, a handle 92 is provided on the front side of the filter frame 91, and multiple pulleys 93 are rotatably connected to the lower sides of the left and right parts of the filter frame 91.

[0026] After scraping and grinding, the concrete on the surface of the template falls into the filter frame 91 through the gap between the transmission belt and the mounting frame 1. The rear part of the mounting frame 1 is a curved surface structure, which facilitates the concrete to slide along the curved surface into the filter frame 91. The water flow can flow into the bottom of the mounting frame 1 through the gap on the filter frame 91, and then be discharged through the drainage hole at the bottom of the mounting frame 1. When the scraping is completed, grab the handle 92 and pull the filter frame 91 outward. The pulley 93 makes it easier to pull the filter frame 91, thereby removing the concrete debris after hanging out.

[0027] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
