Device for enhancing hitting power of breaking hammer
According to the device for enhancing the hitting power of the breaking hammer, the oil inlet end of the breaking hammer is connected with a main pump, the main pump is connected with an oil tank through a pilot-operated overflow valve, and the pilot end of the pilot-operated overflow valve is connected with a pilot pump through an electromagnetic valve; a delay reversing device and a delay reversing groove are arranged in the breaking hammer, the delay reversing groove is parallel to the reversing signal groove, the delay reversing device is arranged between the delay reversing groove and the reversing signal groove, and the delay reversing device is connected with the pilot end of the pilot overflow valve. And the delay reversing device blocks the delay reversing groove and the reversing signal groove under the action of the pilot hydraulic oil. According to the device for enhancing the hitting power of the breaking hammer, the secondary overflow device and the delayed reversing device are arranged, the secondary overflow device can improve the arrangement pressure of a system and is used for improving the hitting power, the delayed reversing device can increase the nitrogen pressure and prolong the hitting stroke and is used for improving the hitting power, and the working efficiency of the breaking hammer is greatly improved; and meanwhile, the hitting power of the breaking hammer is further improved.
一种增强破碎锤打击力的装置，破碎锤的进油端连接有主泵，主泵通过先导式溢流阀连接油箱，先导式溢流阀的先导端通过电磁阀连接有先导泵；破碎锤内设有延迟换向装置和延迟换向槽，延迟换向槽与换向信号槽平行，延迟换向装置设置在延迟换向槽和换向信号槽之间，延迟换向装置与先导式溢流阀的先导端连接在一起，延迟换向装置在先导液压油的作用下阻断延迟换向槽和换向信号槽。本发明的增强破碎锤打击力的装置，设有二次溢流装置和延迟换向装置，二次溢流装置可提高系统的整理压力，用以提升打击力，延迟换向装置可增高氮气压力，还可可延长打击行程，用以提升打击力，大幅提高了破碎锤工作效率，同时进一步提升了破碎锤的打击力。
