Description

Technical Field

[0001] The utility model relates to the technical field of concrete precast component plastering devices, and particularly relates to an elastic cantilever plastering device. Background Art

[0002] In the field of concrete precast component production, the surface of concrete after pouring is generally rough and needs to be plastered and polished. Since small precast components generally have complex shapes and various types, at present, the method of plastering small concrete precast components mostly adopts manual plastering and polishing, such as using a manual plastering trowel for plastering and polishing, or using a baffle-type plastering machine for plastering and polishing. Using a manual plastering trowel to plaster and polish the surface of small precast components has a very high labor intensity, low construction efficiency, and a large number of operators are required for the operation surface. The existing baffle-type plastering machine has a small plastering range and cannot play a good role in plastering and polishing the rough and uneven concrete surface, which affects the construction quality and progress. For example, the Chinese patent document with the publication number: CN220428715U discloses a concrete plastering device for precast component preparation, including an outer frame. The bottom of the outer frame is rotatably sleeved with a bottom wheel set. The inside of the outer frame is slidably sleeved with a limiting frame. The bottom of the limiting frame is fixedly connected with an adjusting frame. An electric motor I is installed outside the adjusting frame. The outside of the output shaft of the electric motor I is fixedly sleeved with a threaded rod. The outside of the threaded rod is threadedly sleeved with a scraping table. The inside of the scraping table is slidably sleeved with a limiting screw tube. An electric motor II is installed outside the outer frame. The outside of the output shaft of the electric motor II is fixedly sleeved with a screw rod. The screw rod is threadedly sleeved at the bottom of one side of the limiting frame. The plastering range of this plastering device is limited by the outer frame, and the scraping table can only reciprocate in one direction, and cannot complete the plastering and polishing work on the rough concrete surface. For the uneven concrete surface, the leveling effect is not good. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an elastic cantilever plastering device with high plastering work efficiency and good plastering and polishing effects when facing uneven or rough concrete surfaces.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0027] Embodiment 1

[0028] Figures 1 to 5 An embodiment of the elastic cantilever troweling device of the present utility model is shown. The elastic cantilever troweling device of this embodiment includes an elastic trowel blade 1 and a driving mechanism 3 for changing the troweling position of the elastic trowel blade 1. The elastic trowel blade 1 includes a troweling part 11 and a connecting part 12. The connecting part 12 is connected to the driving mechanism 3, and the troweling part 11 is a cantilever structure.

[0029] The elastic trowel blade 1 of this embodiment includes a troweling part 11 and a connecting part 12. The vibrator 4 is in direct contact with the troweling part 11 of the elastic trowel blade 1. Since the troweling part 11 is a cantilever structure, when the troweling part 11 contacts the uneven concrete surface, it can produce a certain deformation to closely adhere to the concrete surface and generate a reverse elastic force. When troweling, the elastic force generated by the troweling part 11 is applied to the concrete surface, making the rough or uneven concrete surface tend to be flat and smooth. The elastic cantilever troweling device of this embodiment has good troweling and finishing effects on rough or uneven concrete surfaces, and has a high degree of automation and high working efficiency, which is beneficial to reducing labor costs.

[0030] Furthermore, in this embodiment, the elastic cantilever troweling device further includes a vibrator 4. The vibrator 4 is connected to the troweling part 11, and an elastic damping component 5 is provided between the connecting part 12 and the driving mechanism 3. Since the troweling part 11 is a cantilever structure and has strong vibration conduction ability, the vibrator 4 is arranged on the troweling part 11. When troweling, the impact force generated by the vibrator 4 and the elastic force generated by the troweling part 11 are both applied to the concrete surface, further improving the troweling and finishing effects on rough or uneven concrete surfaces. The elastic damping component 5 can reduce the vibration transmitted from the vibrator 4 to the driving mechanism 3, avoid the vibration from affecting the service life of the motion driving mechanism 3, and at the same time make the vibration be transmitted to the elastic trowel blade 1 as much as possible to ensure the troweling effect.

[0031] Furthermore, in this embodiment, the elastic damping component 5 includes a first mounting plate 51, a second mounting plate 52, and an elastic member 53 connecting the first mounting plate 51 and the second mounting plate 52. The first mounting plate 51 is connected to the driving mechanism 3, and the second mounting plate 52 is connected to the connecting part 12 (seeFigure 5 ) When the impact generated by the vibrator 4 is transmitted to the elastic damping component 5, the elastic member 53 deforms to absorb the impact, reducing the vibration transmitted to the driving mechanism 3. Specifically, the elastic member can be a component with energy absorption and vibration damping characteristics such as a spring or rubber.

[0032] Furthermore, in this embodiment, a plurality of elastic members 53 are provided and are evenly arranged in the circumferential direction, which is beneficial to reducing the vibration and impact at various locations from being transmitted to the driving mechanism 3.

[0033] Furthermore, in this embodiment, the driving mechanism 3 includes a frame 31, a longitudinal moving trolley 32 provided on the frame 31, a transverse moving trolley 33 provided on the longitudinal moving trolley 32, and a lifting member 34 (such as a cylinder, an oil cylinder, a lead screw nut mechanism, etc.) provided on the transverse moving trolley 33. The lifting member 34 is connected to the connecting portion 12. Preferably, a longitudinal moving track 35 cooperating with the longitudinal moving trolley 32 is provided on the frame 31, and a transverse moving track 36 cooperating with the transverse moving trolley 33 is provided on the longitudinal moving trolley 32. The longitudinal moving track 35 can guide the longitudinal moving trolley 32, and the transverse moving track 36 can guide the transverse moving trolley 33, which is beneficial to ensuring the stability and safety of the longitudinal moving trolley 32 and the transverse moving trolley 33 during the moving process and avoiding deviation. During use, the lifting member 34 can drive the elastic trowel blade 1, the vibrator 4, etc. to lift as a whole, so that the elastic trowel blade 1 can plaster the surfaces of components at different heights, and can also adjust the pressing degree on the surface of the component. The transverse moving trolley 33 moves on the transverse moving track 36 on the longitudinal moving trolley 32, which can drive the lifting member 34 to move horizontally. Correspondingly, the longitudinal moving trolley 32 moves on the longitudinal moving track 35 on the frame 31, thereby driving the transverse moving trolley 33 and the lifting member 34 to move longitudinally, so that the elastic trowel blade 1 can reach any position of the component for plastering, and the structure is simple and effective.

[0034] Furthermore, in this embodiment, the lifting member 34 and the connecting portion 12 are connected through a rotating mechanism 2. The rotating mechanism 2 can drive the elastic trowel blade 1 to rotate. The elastic trowel blade 1 can turn at any time during the plastering process without plastering according to a specific path, and the plastering is more flexible and convenient. Specifically, the rotating mechanism 2 drives the elastic damping component 5 and the elastic trowel blade 1 to rotate through a servo motor 21, a driving wheel 22, a driven wheel 23, and a synchronous belt 24 (see Figure 5 ), and of course, in other embodiments, the elastic damping component 5 and the elastic trowel blade 1 can also be driven to rotate through a meshing gear set, which will not be elaborated here.

[0035] The usage method of the elastic cantilever plastering device of the present utility model is as follows:

[0036] First, the transverse moving trolley 33 and the longitudinal moving trolley 32 drive the elastic trowel blade 1 to move directly above the precast member to be troweled. Subsequently, the lifting component 34 drives the elastic trowel blade 1 to contact the concrete surface of the precast member and applies appropriate pressure. Then, the vibrator 4 is started to drive the elastic trowel blade 1 to vibrate and level the surrounding concrete surface. The transverse moving trolley 33 and the longitudinal moving trolley 32 then drive the elastic trowel blade 1 to move longitudinally and transversely on the concrete surface of the precast member to level it. During the movement, the rotation mechanism 2 is started as needed to change the orientation of the elastic trowel blade 1. After the troweling operation of the precast member is completed, the vibrator 4 and the rotary servo motor 21 stop working, and the lifting component 34 raises the elastic trowel blade 1 to separate it from the concrete surface. After separation, the transverse moving trolley 33 and the longitudinal moving trolley 32 drive the elastic trowel blade 1 to move directly above the next precast member to be troweled. Repeat the above steps until the troweling operations of all precast members are completed.

The elastic cantilever troweling device of this embodiment is basically the same as the first embodiment, except that: in this embodiment, the motion driving mechanism 3 is a multi-axis robotic arm 6, that is, the multi-axis robotic arm 6 is used to drive the elastic trowel blade 1 to move and turn on the concrete precast member, so as to perform troweling and finishing operations. Compared with the first embodiment, the advantages of this embodiment are: there is no need to set up multiple components such as the frame 31, the longitudinal moving trolley 32, the transverse moving trolley 33, and the lifting component 34, the floor area is small, and the installation and use processes are more convenient.

That is, the motion driving mechanism 3 in this embodiment is a combination of the first embodiment and the second embodiment, and can also realize the movement of the elastic trowel blade 1 on the member for troweling work. Compared with the second embodiment, the advantages of this embodiment are: since the multi-axis robotic arm 6 can move longitudinally and transversely, the movement range of the elastic trowel blade 1 is wider, and it is more suitable for the troweling operation of large concrete precast members.
