Description

Technical Field

[0001] This utility model relates to the technical field of template cleaning devices, specifically to a quick grinding and cleaning device for templates after demolding of subway prefabricated components. Background Technology

[0002] With the acceleration of urbanization in China, the scale of subway construction is unprecedented. To improve efficiency, ensure quality, and reduce costs, prefabricated construction has become the mainstream construction method for subway stations, tunnel segments, entrances, and other structures. Precast components (such as tunnel segments, wall panels, beams, and columns) are mass-produced in factories, and the turnover efficiency of the molds directly determines production capacity and cost. However, after the molds are demolded, residues remain on the mold surface. If these residues are not thoroughly cleaned, problems such as honeycomb, pitting, and dimensional deviations in the surface of the next batch of precast components will occur. Therefore, achieving rapid, thorough, and non-destructive cleaning of the molds is a key link in ensuring high-quality and high-efficiency production of precast components.

[0003] Chinese utility model patent CN219562555U discloses a handheld grinding device, which includes "a handle, a motor, a grinding disc, and a power cord. The motor is installed in a mounting groove at the top of the handle, and the output shaft of the motor passes through a through hole in the handle and is fixedly connected to the top center of the grinding disc. The power cord is installed at the bottom of the handle and is electrically connected to the motor and an external power source. A mounting bracket is installed between the top of the grinding disc and the bottom of the handle." However, in actual use, workers need to maintain a bent or squatting posture for a long time, which can easily lead to lumbar spine diseases. In addition, when the device is used for grinding and cleaning, the dust is scattered everywhere, which not only harms respiratory health but also requires additional cleaning procedures, making it impractical. Utility Model Content

[0004] The purpose of this utility model is to provide a device for quick grinding and cleaning of templates after demolding of prefabricated subway components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick grinding and cleaning device for templates after demolding of prefabricated subway components, comprising a grinding head, the top surface of the grinding head being installed and connected to the bottom surface of a connecting pipe, the inner wall of the connecting pipe being threadedly connected to the outer wall of an extension rod, the inner wall of the extension rod being threadedly connected to the outer wall of a handle, the side of the handle being installed and connected to one end of a suction pipe, and the other end of the suction pipe being installed and connected to the top surface of a dust collection box;

[0006] The grinding head includes a dust inlet pipe, the top of which is fixedly connected to a mounting flange.

Furthermore, the grinding head is equipped with a dust suction hood, which generates strong suction through a fan inside the dust collection box. The axial air intake is achieved through spiral blades inside the dust suction hood, with the airflow direction aligned with the direction of the grinding debris. This effectively collects over 80% of the grinding material, thus preventing the grinding debris from scattering and enhancing its practicality.

[0013] By adopting the above technical solution, a fan is installed. When the fan is started, the air inside the dust collection box is drawn out, creating a negative pressure zone inside the dust collection box. This generates suction to draw the grinding debris and dust into the dust collection box. The debris and dust in the dust collection box are filtered and collected inside the dust collection box by the filter element. The dust filter on the right side of the fan can effectively prevent external dust from entering the dust collection box.

[0020] To achieve the dust collection effect of this device:

[0021] The connection is further configured such that the internal parts of the connecting tube, the extension rod, and the handle are all interconnected.

[0022] By adopting the above technical solution, dust and debris are sucked in from the dust hood, and then collected in the dust collection box through the connecting tube, extension rod and handle, thus achieving the effect of dust collection.

The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0051] Therefore, the "fan" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application.

[0052] The working process of this rapid sanding and cleaning device for the prefabricated subway components after demolding is as follows:

[0053] Firstly, the user can easily hold the device for grinding by gripping the handle 44 and the handle 42. A counterweight box 45 is set at the top of the handle 44. The counterweight box 45 is connected to multiple counterweight blocks 453 by a buckle 451. The number of counterweight blocks 453 can be flexibly adjusted to achieve the effect of counterweight adjustment (200-500g), which is used to balance the torque of the machine head and reduce the load on the wrist.

[0054] At this time, by starting the drive motor 15, the drive motor 15 drives the grinding disc 17 to rotate at high speed inside the dust collection hood 12 through the shaft 16, thereby achieving the grinding effect. The debris generated during grinding is collected by the dust collection hood 12. The axial air intake is achieved by the spiral blade 13 set inside the dust collection hood 12, and the airflow direction is the same as the direction of the flying debris, which can collect more than 80% of the grinding material.

[0055] The sucked-in dust passes through the dust inlet pipe 11, extension rod 3 and handle 4, and is then collected in the dust collection box 6 through the dust inlet 61 via the dust suction pipe 5 and the connection port 43 on the side of the handle 4. The air inside the dust collection box 6 is drawn out by the fan 63, creating a negative pressure zone inside the dust collection box 6, thereby generating suction to achieve the dust collection effect. The debris and dust sucked into the box are filtered and collected in the dust collection box 6 by the filter element 64. The dust filter 62 on the right side of the fan 63 can effectively prevent external dust from entering the dust collection box 6.

[0056] By setting two detachable extension rods 3, three-level (800 / 1200 / 1500mm) adjustment can be achieved to accommodate users of different heights (1.5-1.9m) for standing use. The connecting tube 2, extension rod 3 and handle 4 can be connected to each other by threaded installation through threaded holes 22 and 32 and threaded caps 31 and 41.

[0057] The dust inlet pipe 11 and the connecting pipe 2 are fixedly connected by bolts through mounting flange 111 and mounting flange 21. During this process, multiple protrusions 112 are inserted into the anti-rotation groove 211 in a one-to-one correspondence, so that the dust inlet pipe 11 and the connecting pipe 2 are connected and installed firmly.

[0058] Among them, the fan 63 can adopt the existing known model SS4-1, which is a well-known existing technology. It can adopt the above model, but is not limited to this.

[0059] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0061] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only for the purpose of helping to understand the method and core ideas of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that due to the limitations of textual expression, there are objectively infinite specific structures.
