Sealed waterproof jacking mechanism of movable bearing seat

Abstract

The invention discloses a sealed waterproof jacking mechanism of a movable bearing seat. The sealed waterproof jacking mechanism comprises a working roller seat, a sliding rail seat. a sliding block, a protection cover, a locking block and a power source. The movable bearing seat is arranged at one end of the working roller seat. The sliding rail seat is arranged below the working roller seat, and a sliding groove is formed below the sliding rail seat. The sliding block is arranged below the sliding rail seat and connected with the sliding groove in a sliding manner, and the movable bearing seat is installed on the sliding block. The protection cover is arranged around the sliding rail seat and comprises a front baffle, a rear baffle, a left baffle, a right baffle and a lower baffle, and a hollow cavity is defined among the front baffle, the rear baffle, the left baffle, the right baffle, the lower baffle and the sliding rail seat. The locking block is inserted between the sliding block and the sliding rail seat, and the sliding block and the sliding rail seat are locked by pushing the locking block through slope extrusion fit. The power source is provided with a push rod, and the push rod is located in the cavity of the protection cover. The push rod acts on the locking block and the sliding block so as to drive the locking block and the sliding block to move forwards along the sliding rail seat together and to be kept at the preset position. The protection cover not only plays a waterproof role on the push rod, but also plays a waterproof role on the slide rail seat.

Description

technical field

[0001] The invention relates to the field of derusting treatment of steel plates and wires, in particular to a sealed and waterproof jacking mechanism for a movable bearing seat. Background technique

[0002] At present, there are two ways to remove rust on the surface of the steel plate, pickling and physical grinding. The pickling method causes serious environmental pollution and does not meet the long-term requirements of environmental protection; physical grinding generally uses scale-breaking rollers to polish the steel plate. To improve work efficiency, when the scale breaking roller is worn out and cannot be used, it needs to be replaced. If the scale breaking roller needs to be replaced, the descaling device must be able to disassemble and install the scale breaking roller, that is, it must have a movable relative frame. The connection mechanism, and the connection mechanism will inevitably wear out when the scale-breaking roller rotates at a high spe...

Examples

specific Embodiment approach

[0049] Such as Figure 1-14 As shown, the present invention provides a sealed and waterproof jacking mechanism for a mobile bearing seat, which includes a work roll seat 1 , a slide rail seat 2 , a slider 3 , a locking block 4 and an elastic driving mechanism 5 .

[0050] The work roll base 1 is used to install the descaling roller 6 for rust removal, and the two ends of the work roll base 1 are respectively provided with a fixed bearing seat 7 and a movable bearing seat 8; When the roll 6 is worn to the extent that the derusting effect cannot meet the processing requirements, a new scale-breaking roll 6 needs to be replaced. The working roll base 1 separates or engages the scale-breaking roll 6 by moving the bearing seat 8 away from or approaching the fixed bearing seat 7 to achieve The purpose of changing rolls.

[0051] Specifically, the slide rail seat 2 is fixedly connected to the bottom of the work roll seat 1, and a chute is provided under the slide rail seat 2. The sl...
