  • Part 11 is formed, and the foremost part is divided into a plurality of parts and claws 7a, 7a ', 7b are attached to the tip, and the rear ends of the arms 2a, 2b are driven by a hydraulic cylinder.
  • the reinforced concrete flat plate is crushed by the wide arms 2a and 2b using the building crusher 1 that opens and closes the arm tip and crushes the target object over the entire width of the arms 2a and 2b. Therefore, unlike conventional building crushers, concrete debris 90 which was destroyed but did not become small as shown in Fig. 14 was generated. There. Therefore, it is possible to prevent a large vibration and noise from being generated due to an impact when the concrete debris 90 falls to the ground.
  • atomized water is sprayed from the center of the crushing arm so as to widely wrap up near-micro dust generated from the reinforced concrete part of the crushing object.
  • it is useful in the field of demolition and crushing of reinforced concrete structures, and is particularly suitable for demolition of reinforced concrete structures in densely populated residential areas where scattering of dust in the vicinity may cause environmental problems.
  • the structure crusher of the present invention is configured to supply water to the water spray nozzle at the lower end of the side plate via a pipe provided inside the cylinder outer cylinder and a water supply pipe which is provided by crawling around the inside of the side plate. Therefore, even if the building crusher is roughly handled, the pipeline for supplying water to the sprinkler nozzle will not be damaged.
  • the watering nozzle is embedded and fixed in the hole provided between the lower ends of the side plates, the watering nozzle does not directly interfere with the object to be crushed, and the nozzle is prevented from being deformed or crushed. You.
  • the protector that protects the sprinkling nozzle is extremely strong because it is integrally formed by the side plate, and does not catch on the object to be crushed unlike the conventionally used external nozzle cover and nozzle holder. However, the protector itself is not damaged.
  • the watering nozzle is provided on the distal end side of the rotating portion of the link mechanism, the sprayed water does not splash on the rotating portion and the grease of the rotating portion is not washed away. Further, the watering nozzle is protected by a replaceable cover member. Therefore, it has a durable spray watering structure that is less likely to damage or break down the watering nozzle and water supply pipe. Therefore, it is useful in the field of demolition and crushing of structures made of hard reinforced concrete, and is preferable because it can withstand the collision of heavy reinforced concrete debris.
  • the water supply system of the present invention damage to the water supply hose can be prevented, and the water can be supplied from the water supply tank to the building crusher safely and efficiently through the water supply hose at low cost. Therefore, it is useful for dismantling sites where there is a risk of damage to the water supply hose due to the scattering of reinforcing bars and concrete lumps on the ground, and it is meaningful because it also provides economic efficiency.

Abstract

Une paire de bras (2A et 2B) dont les parties intermédiaires sont portées par des supports de bras (6a et 6b) est prévue. Une paire de lames à cisailler (48a et 48b) permettant de cisailler un objet, est fixée au parties d'extrémité des bras (2a et 2b), à proximité des parties portées. Plusieurs orifices traversants (8) sont formés dans les parties intermédiaires des parties d'extrémité. Les parties avant des parties d'extrémité sont divisées en plusieurs portions auxquelles des mâchoires (7a, 7a, 7b) sont fixées. Les parties d'extrémité arrière des bras (2a et 2b) sont commandées par un vérin hydraulique qui permet l'ouverture ou la fermeture des parties d'extrémité des bras de sorte que l'objet soit broyé sur la largeur totale des bras (2a et 2b). Afin d'empêcher la poussière provenant des parties broyées de se disperser, de l'eau en brouillard est pulvérisée par des buses de pulvérisation (46a et 46b) en direction des parties d'extrémité des bras (2a et 2b) de sorte que lesdites parties broyées soit recouvertes d'eau.
