Description

Technical Field

[0001] The utility model relates to the technical field of concrete pavement construction machinery, in particular to a protective ring structure for a trowel machine. Background Art

[0002] During the construction of concrete pavements, floors, floors, and plate-shaped prefabricated parts, the construction surfaces need to be smoothed to improve the density and wear resistance of the concrete surface. The traditional concrete surface smoothing operation is done manually using a trowel to smooth it back and forth, which is labor-intensive and inefficient. With the development of science and technology, a trowel machine is designed to replace manual smoothing operations, which greatly improves the efficiency of concrete pavement smoothing and reduces the labor intensity of workers. Since the trowel machine smoothes the concrete surface through the rapidly rotating trowel disc at the bottom, if the rapidly rotating trowel disc is directly exposed to the working environment, its use safety is low. Therefore, the designer installed a protective ring on the outside of the trowel disc to avoid accidental injury and to prevent the trowel disc from colliding with external objects and being damaged.

[0003] The existing patent application number: 201810258026.4 discloses a protective ring structure for a trowel machine, which has a compact structure, is easy to operate, has good construction protection effect, high strength, and long service life. In the above-mentioned prior art, the device and the trowel machine are still fixedly connected by bolts and nuts. Since the trowel machine generates high-frequency vibrations when working, it is easy to cause the bolts and nuts to loosen or fall off, affecting its protection effect. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figures 1 to 3 As shown, a protective ring structure for a trowel machine includes a top plate 1 and a limiting sleeve 2 fixed on the top plate 1, and the protective ring structure for the trowel machine also includes:

[0031] A connecting seat 4 is plugged into the through slot 3 provided at the top of the limiting sleeve 2. The connecting seat 4 is in an inverted convex shape as a whole. The top of the connecting seat 4 is fixed on the trowel machine. The output end of the trowel machine passes through the connecting seat 4 and extends to the bottom of the top plate (1).

[0032] A plurality of locking members 5 are used to limit and fix the connecting seat 4 in the through groove 3.

[0033] The locking member 5 comprises:

[0034] The transverse insertion rod 52 is plugged into the transverse grooves 51 on both sides of the limiting sleeve 2, and a transverse slot 58 is provided on the connecting seat 4. When the transverse insertion rod 52 is plugged in transversely, one end thereof passes through one of the transverse grooves 51, the transverse slot 58 and the remaining transverse groove 51 in sequence.

[0035] The two ends of the U-shaped sleeve 54 are inserted into two through holes 53 arranged on the top of the top plate 1 , and the cross beam on the top of the U-shaped sleeve 54 is sleeved with the buckle groove 55 arranged on the top of the cross-insertion rod 52 .

[0036] A stopper 56 is fixed to the bottom end of the U-shaped sleeve 54 .

[0037] The spring 57 is slidably mounted on the outside of the two ends of the U-shaped sleeve 54 , and the spring 57 is located between the top of the stopper 56 and the top plate 1 .

[0038] During assembly, first insert the bottom of the connecting seat 4 into the through slot 3 on the limiting sleeve 2, and align the transverse slot 58 on the connecting seat 4 with the transverse slot 51, then pass one end of the transverse insertion rod 52 through the U-shaped sleeve 54 on one side of the outer side of the limiting sleeve 2, and then pass through the transverse slot 51 on one side of the limiting sleeve 2, the transverse slot 58 on the connecting seat 4 and the transverse slot 51 on the other side of the limiting sleeve 2 in sequence, and then pass into the U-shaped sleeve 54 on the other side of the outer side of the limiting sleeve 2, and finally put the crossbeam on the top of the U-shaped sleeve 54 into the buckle In the groove 55, the horizontal freedom of the cross-insertion rod 52 is constrained, and the vertical freedom of the cross-insertion rod 52 is constrained by the cross-slot 51 and the cross-slot 58, so that the interlocking effect between the limit sleeve 2, the connecting seat 4, the cross-insertion rod 52 and the U-shaped sleeve 54 is achieved, so that the fixed connection between the limit sleeve 2 and the connecting seat 4 is free of threaded connectors, thereby avoiding the high-frequency vibration generated during the operation of the trowel machine to affect the firmness and stability of the connection between the limit sleeve 2 and the connecting seat 4, and the installation operation is also relatively simple and efficient.

[0039] In this embodiment, the transverse slot 58 corresponds to the transverse slot 51 , and the transverse slot 58 matches the transverse insertion rod 52 .

[0040] The locking members 5 are relatively distributed on two sides of the exterior of the limiting sleeve 2 , and the locking members 5 correspond to the transverse grooves 51 .

[0041] With such a design, when installed between the limit sleeve 2 and the connecting seat 4, the two transverse grooves 51 can be aligned with the two ends of the transverse slot 58 and maintain a coaxial relationship. At the same time, when the U-shaped sleeve 54 is pulled up, the transverse penetration direction inside it is aligned with the transverse groove 51, so that the transverse insertion rod 52 can be smoothly passed from the locking piece 5 on one side of the outside of the limit sleeve 2 to the locking piece 5 on the other side of the outside of the limit sleeve 2. In this process, it is ensured that the transverse insertion rod 52 passes through the inside of the transverse slot 58 on the connecting seat 4, so that the connecting seat 4 can be fixed in the through slot 3 on the limit sleeve 2 by the transverse insertion rod 52, and the locking and fixing effect of the locking piece 5 on the two ends of the transverse insertion rod 52 is cooperated, so as to realize the interlocking effect between the top plate 1, the limit sleeve 2, and the connecting seat 4, improve the installation accuracy and smoothness, and reduce the difficulty of the installation operation.

[0042] In this embodiment, the through groove 3 passes through the top plate 1 downward, and the through groove 3 matches the bottom of the connecting seat 4. This design allows the output end of the trowel machine to pass through the top plate 1 and extend to the bottom of the top plate 1, so that the trowel disc can be installed directly below the top plate 1, and the bottom of the connecting seat 4 is limited and fixed by the through groove 3, and the connecting seat 4 is fixed with the locking piece to completely limit and fix the connecting seat 4, so as to avoid the problem of shaking of the connecting seat 4 and the limiting sleeve 2 during the use of the trowel machine, which affects the troweling effect of the trowel machine on the concrete surface.

[0043] In the present embodiment, the protective ring structure for the trowel machine also includes a protective ring member 6 fixedly mounted on the outside of the top plate 1, and the protective ring member 6 is used to protect the trowel optical disc at the output end of the trowel machine. Since the trowel optical disc is located directly below the top plate 1, the protective ring member 6 is convenient for covering the top of the trowel optical disc from top to bottom, isolating the trowel optical disc from contact with external objects in the horizontal direction, avoiding collision and causing accidental danger or damage, which can not only protect the integrity of the trowel optical disc, but also improve the safety of the use of the trowel machine, killing two birds with one stone.

[0044] In this embodiment, the retaining ring member 6 includes:

[0045] A plurality of downwardly bent support bars 61 are fixed to the outside of the top plate 1 .

[0046] A plurality of guard rings 62 are fixedly sleeved horizontally on the outside of all the support bars 61 .

[0047] The guard rings 62 are evenly distributed on the support bars 61, and the diameters of all the guard rings 62 decrease from bottom to top. In this design, a plurality of downwardly bent support bars 61 are evenly arranged on the circumference of the outside of the top plate 1, and a plurality of guard rings 62 are fixedly sleeved on the outside of the support bars 61, and the guard rings 62 connect all the support bars 61 in series to form a whole, and cooperate with the design that the diameters of the plurality of guard rings 62 decrease from bottom to top, so that the guard ring member 6 forms an arc-shaped protective surface on the outside of the optical wiper, so that the protective surface can cover the outside of the optical wiper to separate it from external objects, thereby achieving the effect of protecting the optical wiper, and preventing people from accidentally touching the optical wiper and getting injured. It is also convenient to reserve enough space between the bottom of the top plate 1 and the optical wiper on the output end of the trowel, so that the bottom end of the U-shaped sleeve 54, the spring 57 and the stopper 56 can be located inside the guard ring member 6, so that the guard ring member 6 can not only protect the optical wiper, but also reduce the influence of external force on the sleeve stability between the U-shaped sleeve 54 and the buckle groove 55.
