A semi-automatic propulsion device for a rotary kiln lined with a lock-seam steel plate

Abstract

The invention relates to a rotary kiln lining whipstitch steel plate semi-automatic propulsion device which comprises a mobile support limit gear and a propel lever body, wherein the propel lever body comprises a fixing plate, a single-piston hydraulic device, an air pick, a drill rod and a propel head; a cross-type slot is arranged formed on in the propel head; the upper end of the drill rod is connected with the propel head, and the lower end of the drill rod is placed in a drill rod locking spring; the drill rod is connected with the air pick through the drill rod locking spring; the upper side of the single-piston hydraulic device is connected with the air pick, and the lower side of the single-piston hydraulic device is connected onto the fixing plate; the propel lever body can achieve 180-degree rotation through a gear connecting shaft; a limit valve can fix the propel lever body on the limit gear; the single-piston hydraulic device is powered by an electric drive hydraulic station, so that the hydraulic rod of the single-piston hydraulic device can extend; a control valve is mounted at the air pick and is connected with external compressed air which supplies power to the air pick.

Description

technical field [0001] The invention relates to the construction field, in particular to a semi-automatic propulsion device for a rotary kiln lining lock seam steel plate. Background technique [0002] Locking bricks is the final masonry of a ring of bricks using main bricks, inserting bricks, steel plates and fire clay. It is a process of tightly closing the ring bricks. When locking bricks, under normal circumstances, each ring brick needs to insert the locking seam steel plate into the gap between the ring bricks after the masonry is completed in the final stage of brick locking, so as to eliminate the shaking between bricks in the ring brick due to the gap and play a tight role. The function of the brick body in the solid ring brick. [0003] In the prior art, the construction conditions of the lock seam steel plate are very poor. Workers need to use a mallet to drive the steel plate into the brick joint. The construction is time-consuming and laborious. Since the thick...

Problems solved by technology

[0003] In the prior art, the construction conditions of the lock seam steel plate are very poor. Workers need to use a mallet to drive the steel plate into the brick joint. The construction is time-consuming and laborious. Since the thickness of the lock seam steel plate is ≤ 2mm, the stress area of ​​the steel plate is small, and the construction has the following problems: Problem: First of all, due to the uneven strength of the knocking, the steel plate will be deformed; in addition, the direction of the steel plate is not easy to control, and it is easy to hit the nearby brick body, damage the corners of the brick body, and affect the service life of the ring brick. It also affects the construction quality, and, due to the poor working conditions during the construction process, it is easy to cause accidental injuries

However, the above products still have the following deficiencies: manpower is required to support the air hammer, and the physical exertion of workers is too large
