[0002] When statically demolishing concrete walls or columns, a crushing jaw is generally installed at the movable end of the excavator's mechanical arm. Existing crushing jaws generally rotate two hawkbill jaws through hydraulic drive, and use the two hawkbill jaws to crush the concrete.

[0003] When the crushing pliers are crushing concrete, the concrete fragments will splash around through the crushing pliers, which may accidentally injure construction workers. At present, most crushing pliers cannot effectively block the fragments, resulting in the fragments splashing around, and the safety of the crushing process cannot be guaranteed. Utility Model Content

[0004] The utility model provides a concrete static crushing and demolition structure, aiming to solve the problem that the crushing pliers proposed in the above background technology cannot block the flying fragments, thus resulting in low safety in use.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The utility model provides a concrete static crushing and demolition structure, such as Figure 1-6 As shown, the concrete static crushing and demolition structure includes: a bracket 1 arranged at the movable end of the excavator mechanical arm and a connecting rod 2 assembled in the bracket 1; a group of clamps 3 rotatably mounted on the connecting rod 2; a group of hydraulic cylinders 4 respectively hinged on the connecting rod 2 and a group of clamps 3; a mounting frame 5 fixedly mounted on one side of the bracket 1, and a connecting plate 6 is slidably mounted on the mounting frame 5; a baffle brush 7 fixedly mounted on the bottom of the connecting plate 6; a baffle 8 arranged on one side of the bracket 1; a limiting mechanism arranged on the mounting frame 5 for limiting the connecting plate 6; and a mounting mechanism arranged on any of the clamps 3 for mounting the baffle 8.

[0028] In this embodiment, when in use, the working pressure and stroke of the hydraulic cylinder 4 are first adjusted to control the clamping force and crushing force of the clamping plate 3 to adapt to concrete blocks of different hardness and thickness. Then, the clamping plate 3 is moved to both sides of the concrete block, so that a group of clamping plates 3 can crush the concrete block. At the same time, the baffle plate 8 and the baffle brush 7 contact the concrete block through the clamping plate 3, and then wrap the concrete block inside. The fragments splashed during crushing are blocked by the baffle brush 7 and the baffle plate 8, so as to ensure that the fragments will not splash around. Since the baffle plate 8 is only provided on one side of the clamping plate 3, the clamping plate 3 close to the excavator side is not provided with the baffle plate 8, so that it is convenient for construction personnel to observe the working conditions of the clamping plate 3, which is conducive to the precise crushing of concrete blocks.

[0029] By using the baffle brush 7 and the baffle plate 8 in combination, the flying fragments can be effectively blocked and captured, thereby improving the safety of the crushing process and facilitating use.

[0030] In a further preferred embodiment of the utility model, the limiting mechanism includes an installation box 9, a slider 10, a return spring 11 and a card plate 12, the installation box 9 is fixedly installed on the top of the installation frame 5, a slide rod is fixedly installed in the installation box 9, the slider 10 and the return spring 11 are both mounted on the slide rod, the card plate 12 is fixedly installed on one side of the slider 10, and the card plate 12 is in sliding contact with the connecting plate 6.

[0031] In this embodiment, when the brush 7 needs to be replaced, first slide the card plate 12 so that the card plate 12 drives the slider 10 to slide along the slide rod, so that the slider 10 presses the reset spring 11, and the reset spring 11 contracts. At the same time, the card plate 12 slides along one side of the connecting plate 6, so that the card plate 12 slides away from the connecting plate 6. Then the brush 7 can be removed for replacement. The operation is relatively quick. The connecting plate 6 is limited by the card plate 12 to be fixed in the mounting frame 5. The fixation is relatively quick and also facilitates the subsequent loading and unloading operations of the connecting plate 6.

[0033] In this embodiment, before assembling the connecting plate 6, first pull the card plate 12 to make the limiting groove 15 on one side of the card plate 12 slide to the side of the limiting rod 14, then slide the limiting rod 14 to make the limiting rod 14 slide along the fixing block 13 to make the limiting rod 14 slide into the limiting groove 15, then release the card plate 12 to make the card plate 12 slide down due to the elastic force of the return spring 11, and at the same time, the top of the limiting rod 14 is close to the limiting groove 15 to limit the card plate 12 and fix the card plate 12, and then the connecting plate 6 can be assembled.

[0034] In a further preferred embodiment of the present invention, the tops of the limiting rod 14 and the limiting groove 15 are both arranged in an inclined shape, and the materials of the brush stop 7 and the baffle plate 8 are both rubber materials.

[0035] In this embodiment, the tops of the limiting rod 14 and the limiting groove 15 are both arranged in an inclined shape, thereby ensuring that the limiting rod 14 will not separate from the limiting groove 15 when limiting the clamping plate 12, which is beneficial to improving the limiting effect.

[0036] In a further preferred embodiment of the utility model, the mounting mechanism includes an L-shaped plate 16, a U-shaped frame 17 and a positioning rod 18, the L-shaped plate 16 is fixedly mounted on one side of the clamping plate 3, the U-shaped frame 17 is fixedly mounted on the top of the baffle 8, the U-shaped frame 17 is slidably connected to the L-shaped plate 16, the positioning rod 18 is slidably mounted on one side of the U-shaped frame 17, and the positioning rod 18 is slidably connected to the L-shaped plate 16.

[0037] In this embodiment, when the baffle 8 needs to be replaced, the positioning rod 18 is first removed from the L-shaped plate 16, and then the U-shaped frame 17 is slid so that the U-shaped frame 17 slides along the L-shaped plate 16 and slides the U-shaped frame 17 away from the L-shaped plate 16 to complete the disassembly of the baffle 8. The disassembly is relatively quick, and the U-shaped frame 17 is quickly installed through the positioning rod 18.

[0039] In this embodiment, when the positioning rod 18 needs to be removed, the positioning block 19 is first pressed to make the positioning block 19 slide along the inner wall of the installation groove, so that the positioning block 19 presses the connecting spring to shrink the connecting spring, and the positioning block 19 slides into the installation groove. After that, the positioning rod 18 can be taken out, and the positioning block 19 is used to limit the positioning rod 18 to ensure that it will not separate from the U-shaped frame 17, and the limiting effect is better.

[0040] In a further preferred embodiment of the present invention, one side of the positioning block 19 is arranged in an inclined shape, and one side of the clamping plate 3 is provided with a plurality of teeth.

[0041] In this embodiment, the setting of the teeth can more effectively embed into the concrete block during the crushing process, thereby increasing the clamping stability and the crushing force.

In addition, the teeth can also reduce the friction between the splint 3 and the concrete block, making the crushing process smoother and reducing energy consumption and wear.

[0042] In summary, compared with the related art, the device can effectively block and capture flying fragments, thereby improving the safety of the crushing process and facilitating its use.
