Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rotary furnace masonry, especially relates to a special pushing chuck for lock seam steel plate in rotary kiln lining installation. BACKGROUND

[0002] Rotary kiln equipment is widely used in cement industry, lime calcination, metallurgical industry, chemical industry and hazardous waste treatment industry in China. The lining of these equipment usually uses refractory material, most of which is refractory brick. After the rotary kiln masonry machine is used for masonry, 2-3mm thick lock seam steel plates need to be knocked into the relatively loose position to tighten the bricks in the ring brick.

[0003] The traditional installation method of lock seam steel plate is to use a hammer to knock it in manually. Since the part where the lock seam steel plate is knocked into is usually located at the top of the rotary kiln, the lock seam steel plate needs to be knocked in from the bottom up. The worker needs to hold the hammer and repeatedly knock the side of the lock seam steel plate from the bottom up several times to make the lock seam steel plate completely sink into the refractory brick joint. Since it is knocked in from the bottom up, the direction and force of the hammer head need to be adjusted constantly during the striking process. Each time the hammer head needs to be able to hit the steel plate. If it is off or not handled properly, the lock seam steel plate will be curled and wasted. Therefore, the operator needs to have high skills. Moreover, the knocking requires high physical strength of the operator, and repeated knocking can easily cause overexertion. Multiple people need to be arranged to knock in turns, which increases labor costs and is low in construction efficiency and high in risk. SUMMARY

[0022] The embodiment provides a special pusher chuck for lock seam steel plates, such as Figures 1 to 3 As shown, the propulsion chuck includes a clamping head 1 and a connecting handle 2 for matching and connecting with the propulsion device. The clamping head 1 is connected to the connecting handle 2 by a connecting rod 3. A limiting baffle 7 is provided at the connection part of the connecting handle 2 and the connecting rod 3 to prevent the connecting rod 3 from being inserted into the jackhammer's insertion hole. A groove 4 matching the lock seam steel plate is opened on the side of the clamping head 1 away from the connecting rod 3. A conical helical spring 5 is provided on the outer sleeve of the connecting rod 3. The small end of the conical helical spring 5 is fixed at the position of the connecting rod 3 near the clamping head 1, and the large end of the conical helical spring 5 extends to the outside of the limiting baffle 7. The propulsion device is a pneumatic pick 6. The size of the connecting handle 2 is the same as that of a standard pneumatic pick chisel and can be matched and connected to the pneumatic pick 6. The large end of the conical helical spring 5 matches the outer wall of the pneumatic pick chisel insertion end of the pneumatic pick 6. Generally, the pneumatic pick chisel connector has a locking thread on the outside, and the large end of the conical helical spring 5 can match this locking thread. When the connecting handle 2 is connected to the pneumatic pick 6, the large end of the conical helical spring 5 is locked and connected to the pneumatic pick 6, and the connection state is as follows. Figure 4 As shown.

[0023] In this embodiment, the clamping head 1 is made of a high-cobalt alloy steel plate with dimensions of 25*75*70mm. The width and depth of its groove 4 are both 4mm, which can clamp the seam steel plate tightly to prevent displacement during hammering. The clamping head 1, connecting rod 3, and connecting handle 2 are welded together as a single unit, and their strength is sufficient for hammering. The length of the connecting rod 3 is 180-200mm, and the length of the conical helical spring 5 is 100-120mm. The conical helical spring 5 is fixed to the end of the connecting rod 3 away from the clamping head 1. The spring design provides necessary elasticity to absorb some of the impact force and reduce the reaction force on the pneumatic hammer main unit.

[0024] When using this utility model, such as Figure 4 As shown, the connector 2 is inserted into the pick drill bit hole of the pick 6, and the large end of the conical helical spring 5 is clamped to the pick 6, so that the entire chuck can be accurately installed on the pick 6. When installing the lock seam steel plate, the worker can first insert the lock seam steel plate into the installation position to fix it initially, and then clamp the groove 4 of the head 1 to hold the lock seam steel plate. Then the pick 6 connected to this utility model can be used to knock it. The pick 6 uses compressed air as a power source. The compressed air drives the piston to reciprocate, so that the head continuously hits the lock seam steel plate, efficiently and without deviation, driving the lock seam steel plate into the joint of the refractory brick.

[0025] The pneumatic pick in this embodiment is a G10 / G15 type pneumatic pick. This invention is also compatible with other existing pneumatic pick equipment and has wide applicability.

[0026] The above is only one embodiment of the present application, which is described in more detail, but cannot be understood as a limitation on the scope of the present application.
