[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

If there are descriptions of the first, second and other similar terms, they are only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] like Figure 1-Figure 3 As shown in FIG. 1 , the high-frequency breaker hammer that is easy to disassemble and assemble described in the embodiment of the present application includes a cutter row 3, an excitation box 2 and a connecting assembly 4. Figure 1 The spatial rectangular coordinate system shown in is used to explain the relevant structure of the embodiment of the present application, wherein the direction indicated by the X-axis is the right, the direction indicated by the Y-axis is the rear, and the direction indicated by the Z-axis is the top.

[0025] The rear end of the knife row 3 has at least one plug-in portion, and the front end of the excitation box 2 has a plug-in matching portion that matches the plug-in portion. It should be noted that the number of the plug-in portions and the plug-in matching portions are the same, and the positions of the plug-in portions correspond to each other, so that the knife row 3 and the excitation box 2 are precisely assembled. The knife row 3 and the excitation box 2 are detachably connected through a connecting component 4.

[0026] The embodiment of the present application realizes the rapid alignment between the cutter row 3 and the excitation box 2 through the plug-in part and the plug-in matching part, and the alignment method is fast and accurate, and then the detachable connection between the cutter row 3 and the excitation box 2 is realized through the connecting component 4, thereby greatly reducing the difficulty of disassembly and assembly between the cutter row 3 and the excitation box 2. At the same time, the plug-in alignment method no longer requires a large-sized bolt mounting plate, which is conducive to reducing the weight of the high-frequency breaker and saving costs.

[0027] As an optional embodiment, one of the plug-in parts is provided on opposite sides of the rear end of the knife row 3. For example, the rear end of the knife row 3 may include two tail plates, one on the left and one on the right, which are relatively parallel to each other. A plug-in part may be provided on the left tail plate and the right tail plate of the rear end of the knife row 3, respectively. Correspondingly, a plug-in fitting part may be provided on the left and right sides of the front end of the vibration box 2, respectively. In this way, the front end of the vibration box 2 can be inserted between the two tail plates at the rear end of the knife row 3. Through the cooperation of the plug-in parts and the plug-in fitting parts on the left and right sides between the knife row 3 and the vibration box 2, the alignment between the knife row 3 and the vibration box 2 can be made more accurate, and the force between the two can be made more stable, thereby enhancing the connection strength between the two.

[0028] like Figure 3 As shown, the plug-in portion may include a card plate 31 protruding backwards. Figure 1 As shown, the plug-in fitting portion may include two stop plates 21 spaced apart from each other, and the spacing distance between the two stop plates 21 is consistent with the vertical width of the clamping plate 31. During alignment and assembly, as long as the clamping plate 31 is inserted between the two stop plates 21, it means that the knife row 3 and the excitation box 2 have been assembled to the correct position. At the same time, this matching mode between the clamping plate 31 and the stop plate 21 is not only very convenient for the alignment and assembly between the knife row 3 and the excitation box 2, and can quickly achieve the alignment and assembly between the two, but also can intuitively reflect whether the two are aligned and assembled in place. In addition, this matching mode between the clamping plate 31 and the stop plate 21 can also prevent the relative rotation between the knife row 3 and the excitation box 2, which is beneficial to ensure the connection strength between the knife row 3 and the excitation box 2, and improve the torsional strength between the two.

[0029] In order to further reduce the difficulty of alignment and assembly between the cutter row 3 and the excitation box 2, as shown in FIG. Figure 3 As shown, at least one upper limit plate 32 may be provided on the rear end of the cutter row 3. The upper limit plate 32 may be a strip limit plate horizontally arranged on the upper end of the tail plate of the cutter row 3. The upper limit plate 32 is mainly used to abut against the upper part of the front end of the excitation box 2. When the cutter row 3 is aligned and assembled with the excitation box 2, after the clamping plate 31 is clamped into the two stop plates 21, the upper part of the front end of the excitation box 2 just abuts against the upper limit plate 32. Therefore, the upper limit plate 32 can also be used to judge whether the cutter row 3 and the excitation box 2 are aligned in place. In addition, when the high-frequency breaker performs a striking operation, the upper limit plate 32 can also play a certain limiting role on the upper part of the front end of the excitation box 2 to prevent relative rotation between the cutter row 3 and the excitation box 2. It can also be said that the upper limit plate 32 is conducive to ensuring the connection strength between the cutter row 3 and the excitation box 2 and improving the torsional strength between the two.

[0030] Obviously, one upper limit plate 32 may be provided on opposite left and right sides of the rear end of the cutter row 3, so that the force between the cutter row 3 and the excitation box 2 is more balanced.

[0031] Furthermore, if Figure 3 As shown, at least one front-end limit plate 33 may be provided on the rear end of the knife row 3. The front-end limit plate 33 may be a strip-shaped limit plate vertically provided on the tail plate of the knife row 3. The front-end limit plate 33 is mainly used to abut against the front end of the vibration box 2. Similarly, when the knife row 3 and the vibration box 2 are aligned and assembled, after the clamping plate 31 is clamped into the two stop plates 21, the front end of the vibration box 2 just abuts against the front-end limit plate 33. Therefore, the front-end limit plate 33 can also be used to judge whether the knife row 3 and the vibration box 2 are aligned in place. In addition, when the high-frequency breaker performs a striking operation, the front-end limit plate 33 can also play a certain limiting role on the front end of the vibration box 2 to prevent relative rotation between the knife row 3 and the vibration box 2. It can also be said that the front-end limit plate 33 is also conducive to ensuring the connection strength between the knife row 3 and the vibration box 2, and improving the torsional strength between the two.

[0032] Similarly, a front end limit plate 33 may be provided on opposite left and right sides of the rear end of the cutter row 3, respectively, so that the force between the cutter row 3 and the excitation box 2 is more balanced.

[0033] As mentioned above, the connecting assembly 4 is mainly used to realize the detachable connection between the cutter row 3 and the excitation box 2. It should also be noted here that the cutter row 3 and the excitation box 2 are quickly aligned by the plug-in parts and the plug-in matching parts that cooperate with each other. At the same time, the plug-in parts and the plug-in matching parts, the upper limit plate 32 and the front limit plate 33 can also enhance the connection strength and torsional strength between the cutter row 3 and the excitation box 2. The connection between the cutter row 3 and the excitation box 2 is realized by the connecting assembly 4. Therefore, the number of connecting assemblies 4 required can be greatly reduced, because the connecting assembly 4 does not need to bear a lot of connection force and torque, which is conducive to further reducing the weight of the entire high-frequency breaker.

[0034] As an optional embodiment, the connecting assembly 4 may include a plurality of bolts 41 and nuts 42 for use in combination. A plurality of through holes are provided at corresponding positions of the rear end of the cutter row 3 and the front end of the excitation box 2. For example, the rear end of the cutter row 3 is provided with three through holes in the vertical direction, and the front end of the excitation box 2 is also provided with three through holes in the vertical direction. The positions of these through holes are aligned one by one and are arranged in the left and right directions perpendicular to the excitation direction of the excitation box 2. A bolt 41 is inserted into each pair of aligned through holes of the cutter row 3 and the excitation box 2, and a nut 42 is screwed on the end of the bolt 41. A gasket and a nut fixing buckle can also be provided at the end of the bolt 41 to improve the connection stability of the nut 42. As described in the background technology, the end faces of the cutter row and the excitation box in the prior art are fitted and connected by bolts, and the length direction of these bolts is arranged parallel to the excitation direction of the excitation box, so that during the high-frequency breaker hammer striking operation, the nut connected to the end of the bolt will be subjected to a large extrusion force, and thus it is easy to loosen. In the embodiment of the present application, the bolt 41 is arranged perpendicular to the excitation direction of the excitation box 2 and mainly bears the shear force. The nut 42 at the end of the bolt 41 will not be subjected to the squeezing force and is therefore not easy to loosen.

[0035] In addition, the high-frequency breaker may further include a tooth seat 5, a bucket tooth 6 and a shock-absorbing box 1. The bucket tooth 6 is connected to the front end of the cutter row 3 through the tooth seat 5 to form a vibration output part. The excitation box 2 is hinged in the shock-absorbing box 1.

[0036] In addition, the utility model also provides a construction trolley, which includes the high-frequency breaker hammer as described above. The construction trolley equipped with the high-frequency breaker hammer is more convenient during construction and the cost can be reduced to a certain extent.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above preferred embodiments shall not be regarded as limiting the present invention, and the protection scope of the present invention shall be subject to the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications shall also be regarded as the protection scope of the present invention.
