[0044] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0045] The most critical concept of the present invention is that the guide groove on the guide protrusion can guide the locking piece on the U-shaped groove, so that the locking piece can be quickly and accurately clamped in the positioning hole, avoiding inaccurate positioning during the process of splicing the support frames and affecting the assembly efficiency, and even avoiding decomposition during the crushing of concrete columns due to inadequate assembly, thereby increasing the risk of operation.

[0046] Please refer to Figures 1 to 5 The concrete crushing device provided by the utility model comprises a plurality of support frames 1 connected end to end;

[0047] The two ends of the support frame 1 in the length direction are respectively provided with a guide protrusion 11 and a U-shaped groove 12;

[0048] Both ends of the guide protrusion 11 in the thickness direction are provided with guide grooves 111, and the bottom of the guide groove 111 is provided with a positioning hole 112;

[0049] The two side walls of the U-shaped groove 12 are provided with locking members 2 adapted to the positioning holes 112;

[0050] During assembly, the guide protrusions 11 and U-shaped grooves 12 of adjacent support frames 1 are riveted to each other.

[0051] From the above description, it can be seen that the beneficial effects of the utility model are: providing a concrete crushing device, during assembly, the guide groove 111 on the guide protrusion 11 can guide the locking piece 2 on the U-shaped groove 12, so that the locking piece 2 can be quickly and accurately clamped in the positioning hole 112; compared with the existing concrete crushing device, in the process of splicing the support frames 1 with each other, not only can the situation of inaccurate positioning affecting the assembly efficiency be avoided, but even the problem of decomposition during the crushing of the concrete column due to inadequate assembly can be avoided, thereby increasing the operation risk.

[0052] Furthermore, the locking member 2 includes a rotating shaft 21, a supporting plate 22 and a clamping member 23;

[0053] Both side wings of the U-shaped groove 12 are hinged with a rotating shaft 21;

[0054] A knob 211 is provided at one end of the rotating shaft 21, and a gear 212 is sleeved at the other end;

[0055] The knob 211 is arranged on the outside of the U-shaped groove 12;

[0056] The gear member 212 is disposed on the inner side of the U-shaped groove 12;

[0057] The support plate 22 is sleeved on the outer side of the rotating shaft 21, and the support plate 22 is arranged between the knob 211 and the gear member 212;

[0058] The clamping member 23 is connected to the rotation through the support plate 22, and the axis of the rotation shaft 21 is taken as the rotation shaft 21, and the clamping member 23 is circumferentially distributed on the outside of the rotation shaft 21;

[0059] The clamping member 23 and the gear member 212 are meshed with each other.

[0060] Specifically, a stop gasket is provided on the knob 211. When the knob 211 is rotated to a suitable position, the stop gasket is bent so that the limiting structure of the stop gasket is clamped on the outside of the U-shaped groove 12, thereby limiting the rotation of the knob 211 and preventing the knob 211 from becoming loose during use, thereby causing the adjacent support frame 1 to disassemble.

[0061] Preferably, the end of the rotating shaft 21 where the gear member 212 is provided is also provided with a hemispherical protrusion 213 to reduce the friction force when the guide protrusion 11 and the U-shaped groove 12 are riveted.

[0062] Furthermore, teeth 113 are provided on the inner wall of the positioning hole 112;

[0063] When the guide protrusion 11 and the U-shaped groove 12 are locked, the clamping piece 23 and the teeth 113 are clamped.

[0064] From the above description, it can be seen that by rotating the knob 211, the rotating shaft 21 drives the gear part 212 to rotate, so that the gear part 212 drives the clamping part 23 to approach or move away from the tooth 113, so as to achieve the locking and unlocking effect of the locking part 2 and the positioning hole 112; and compared with the traditional bolt fastening, the locking part 2 can not only ensure the locking effect, but also achieve the purpose of quick tightening and loosening, thereby indirectly improving the overall assembly efficiency.

[0065] Furthermore, the above concrete crushing device further includes an elastic member 3;

[0066] A blind hole 121 is also provided on the side wall of the U-shaped groove 12;

[0067] The elastic member 3 is sleeved on the outer side of the rotating shaft 21;

[0068] Two ends of the elastic member 3 are connected to the bottom of the blind hole 121 and the support plate 22 respectively.

[0069] It can be seen from the above description that, through the expansion and contraction of the elastic member 3, the gear member 212 is indirectly driven to be embedded in the blind hole 121 along the axial direction of the rotating shaft 21, or exposed outside the blind hole 121; so that after the locking member 2 moves to the positioning hole 112, the gear member 212 and the clamping member 23 can be quickly pushed into the positioning hole 112, thereby avoiding the separation of the guide protrusion 11 and the U-shaped groove 12.

[0070] Furthermore, the above concrete crushing device further comprises a crushing head 4 and a driving device 5;

[0071] The crushing head 4 is connected to the movable end of the driving device 5;

[0072] The support frame 1 is sleeved on the outer side of the fixed end of the driving device 5;

[0073] During assembly, the moving directions of the crushing heads 4 intersect at the same point.

[0074] Specifically, the driving device 5 is any commercially available device that can move an object in a straight line, such as a hydraulic cylinder or a pneumatic cylinder, etc., and the driving device 5 is connected to the peripheral oil pump and air source device through the pipeline 7.

[0075] From the above description, it can be seen that the design has made specific improvements to the component structure of the concrete crushing device. The support frame 1 provides structural support for the positioning of the crushing head 4 and the driving device 5; the driving device 5 provides power support for the movement of the crushing head 4; and it is ensured that the moving directions of each crushing head 4 intersect at the same point, so that each crushing head 4 can form a combined force when crushing the concrete column, thereby improving the overall crushing effect.

[0076] Furthermore, a lifting ring 6 is provided on the supporting frame 1 .

[0077] From the above description, it can be seen that the lifting ring 6 provides structural support for the lifting of the concrete crushing device, which can not only improve the flexibility of each crushing device during assembly, and facilitate the staff to better adjust the docking angle of each support frame 1 to improve the overall assembly efficiency, but also after the assembly work is completed, the concrete crushing device can be lifted on any peripheral lifting equipment, so that the concrete crushing device can be suitable for the crushing of concrete columns of various heights.
