This embodiment provides a device is chiseled off in steel bridge deck pavement, can improve the work efficiency who chisels off the asphalt cement.

The steel deck pavement chiseling device comprises a hard shell 10 and a compaction assembly 20.

Referring to fig. 1 to 4, fig. 1 is a schematic view of a steel bridge deck pavement chiseling device and a bucket 40 in this embodiment 1, fig. 2 is a perspective view of the steel bridge deck pavement chiseling device in this embodiment 1, fig. 3 is a cross-sectional view of the steel bridge deck pavement chiseling device in this embodiment 1, and fig. 4 is a side view of the steel bridge deck pavement chiseling device in this embodiment 1.

One end of the hard shell 10 is wedge-shaped and forms a chiseled lower edge 11. The pressing assembly 20 is arranged at one end of the hard shell 10 far away from the chiseling lower edge 11, the pressing assembly 20 is provided with a pressing part 21, and the pressing part 21 can move relative to the hard shell 10 to adjust the distance between the pressing part and the hard shell 10 and is used for fixing or separating the hard shell 10 to or from a bucket tooth 41 of the excavator.

In the above-mentioned in-process of realizing, the device is chiseled in steel bridge deck pavement can be installed on excavator dipper tooth 41, and the excavator utilizes the device to chiseled in steel bridge deck pavement to chiseled asphalt cement.

An operator can adjust the pressing assembly 20, control the distance between the pressing part 21 and the hard shell 10, and easily fix or separate the hard shell 10 on or from the excavator bucket teeth 41; simultaneously, the one end of stereoplasm shell 10 is the wedge, and its thickness reduces gradually, forms chisel and removes lower limb 11, and the effect face of chiseling lower limb 11 is little, has sharp smooth characteristic, can carry out the work of chiseling asphalt mastic high-efficiently. Meanwhile, the steel bridge deck pavement chiseling device can effectively protect the bucket teeth 41 of the excavator, and abrasion of the bucket teeth 41 caused by chiseling asphalt mastic is avoided; meanwhile, the hard shell 10 is made of a material that has a certain hardness and can remove asphalt mastic, including, but not limited to, a metal material, an alloy material, or a high-strength composite material.

Referring to fig. 3, the hard shell 10 can be seen as being constructed in two parts, the part with the chiseled lower edge 11 being referred to as the lower part, the remainder being referred to as the upper part, the upper part being thicker than the lower part. The pressing assembly 20 is disposed on the upper portion, one of the edges of the upper portion that transitions to the lower portion is a bevel, and the other edge opposite the bevel may be a bevel or a straight edge, so as to form a wedge shape, and the bevel forms a sharp and flat chiseled lower edge 11 at the end of the lower portion.

Referring to fig. 3, 4 and 5, fig. 5 is a perspective exploded view of a partial structure of the hard case 10 and the pressing assembly 20 in this embodiment.

The hard shell 10 is of a hollow structure, and an opening 12 is formed in the end face of the hard shell 10, and the opening 12 is far away from the chiseled lower edge 11.

The pressing component 20 further comprises a screw 22, the screw 22 is screwed and penetrates through the surface of the hard shell 10, and one end of the screw 22 is connected with the pressing part 21. The pressing portion 21 is located inside the hard case 10.

It should be noted that the width of the opening 12 may be equal to the width of the bucket tooth 41, so as to ensure that the hard casing 10 is firmly sleeved on the bucket tooth 41, and now the hard casing 10 moves left and right relative to the bucket tooth 41, and the pressing assembly 20 limits the vertical movement of the hard casing 10 relative to the bucket tooth 41, so as to ensure the connection strength between the hard casing 10 and the bucket tooth 41.

In the process of realizing, the bucket teeth 41 of the excavator can extend into the hard shell 10 through the opening 12 of the hard shell 10, and an operator can adjust the distance between the pressing part 21 and the inner wall of the hard shell 10 by screwing the screw rod 22, so that the steel bridge deck pavement chiseling device can be conveniently disassembled and assembled on the bucket teeth 41.

In the present disclosure, a nut groove 13 is formed on the surface of the hard case 10, a first nut 23 is embedded in the nut groove 13, a screw 22 is screwed to the first nut 23, and an external screw shank 24 is formed at one end of the screw 22 located outside the hard case 10.

In the implementation process, the first nut 23 is embedded, so that the manufacture of the hard shell 10 can be simplified, the hard shell 10 only needs to be provided with a thread groove, and the manufacture difficulty of the hard shell 10 is reduced. In other embodiments, a threaded hole may be formed in the surface of the hard shell 10 to achieve the same technical effect. The operator can easily screw the screw 22 by screwing the external screw 24, and adjust the distance between the pressing portion 21 and the inner wall of the hard case 10.

Optionally, the compression portion 21 includes a first cushion 25.

In the implementation process, the first soft pad 25 includes, but is not limited to, a rubber pad and other structures with a large friction force, and the friction is increased by the first soft pad 25, so that the connection relationship between the steel bridge deck pavement chiseling device and the bucket teeth 41 can be improved; meanwhile, it should be noted that the larger the surface area of the first cushion 25 is designed, the higher the friction force between the first cushion and the bucket teeth 41 is; meanwhile, it should be noted that an internal screw handle 26 may be formed at one end of the screw rod 22 located inside the hard shell 10, and the cross section of the internal screw handle 26 is larger than that of the screw rod 22, and is connected with the first soft cushion 25 through the internal screw handle 26, so as to facilitate a good connection relationship between the first soft cushion 25 and the screw rod 22.

Similarly, in this embodiment, the inner wall of the hard shell 10 may be provided with a second cushion 27.

In the above implementation, the second cushion 27 includes, but is not limited to, a rubber pad or the like having a structure with a large friction force. When the operator tightens the screw 22, the first cushion 25 and the second cushion 27 can be tightly clamped to the bucket teeth 41, so as to ensure the connection between the steel bridge pavement chiseling device and the bucket teeth 41.

It should be noted that in one possible embodiment, one of the first cushion 25 and the second cushion 27 may be provided, and in the case of only one of the first cushion and the second cushion, the friction force may be increased to ensure the connection relationship between the steel deck pavement chiseling device and the bucket teeth 41, but of course, the effect is better if both the first cushion 25 and the second cushion 27 are provided.

In this embodiment, the hard case 10 is a steel case, and the thickness of the steel case is 3cm to 5 cm.
