Abstract
The utility model discloses an integrated pre-tightening air cylinder device. A sliding baffle (7) and a spring assembly (8) are externally sleeved on a hollow shaft (1) which is sleeved on a piston rod (14); the left end of the hollow shaft (1) is connected with a round nut (2); an end cover (4), a cylinder body (9) and an air cylinder cover (12) are connected with a nut (6) through a screw (5); a piston (11) is arranged on the piston rod (14); a buffer (13) is arranged on the piston (11); and a mounting screw (15) and a mounting nut (16) are arranged on the air cylinder cover (12). A limiting casing (10) is welded on the end cover (4) which is provided with an adjusting bolt (3). The integrated pre-tightening air cylinder device is compact and has large and adjustable pre-tightening force and can reliably realize the compactness of an aluminum guide rod and a bus and the stretching of a clamp in an anode bus lifting framework.
Description
Technical field
This practicality relates to the integrated form power set in the operating process of a kind of aluminum electrolysis industry positive bar lift frame.
Background technology
The effect of the positive bar lift frame that potroom uses is the anchor clamps on the cylinder ventilation promotion piston rod drive positive bar lift frame that makes on it, make aluminium guide bar compress bus, clamp the capsule anchor clamps of aluminium guide bar then with tool to open, at last to lift energising beginning to promote bus.In the process that bus promotes, because the reactive force of anchor clamps upper cylinder, aluminium guide bar and bus are in fit-state all the time.After the bus lifting puts in place, tighten the capsule anchor clamps with instrument, aluminium guide bar and bus are fit together closely.Afterwards, close source of the gas, make anchor clamps be in relaxed state, at last the positive bar lift frame is hung electrolyzer, finish bus and promote action by return spring.If positive bar lift frame supply gas pressure in operating process is not enough or die, then to fit bad between aluminium guide bar and the bus or break away from, this will cause ordinary production and have a strong impact on.
Summary of the invention
The technical problem that this practicality will solve is, a kind of integrated form pretension air cylinder device is provided, this device utilizes the preliminary tension of power set medi-spring self to make aluminium guide bar be adjacent to bus by the anchor clamps in the positive bar lift frame when the positive bar lift frame is operated, and make opening of anchor clamps in the piston rod pulling positive bar lift frame by the cylinder air feed, fit bad between aluminium guide bar that prior art exists and the bus or break away to overcome, have a strong impact on the deficiency of production.
This practicality is by the following technical solutions: slide damper and spring assembly are enclosed within on the tubular shaft outward, hollow shaft sleeve is on piston rod, the tubular shaft left end is connected with round nut, end cap, cylinder body and cylinder head link into an integrated entity by screw rod and nut, piston is arranged on piston rod, snubber is arranged on piston, the installation screw rod is arranged on cylinder head.
On end cap, be welded with spacing collar, with the stroke of limited piston bar, piston.
The adjustment bolt is arranged on end cap.Between slide damper and the end cap, can be by adjusting the effect of bolt, both are reclined mutually or do not recline, to adjust the preliminary tension of spring assembly.
This utility structure compactness, preliminary tension is big and adjustable, can reliably realize aluminium guide bar and bus compress and the positive bar lift frame in the opening of anchor clamps.
Description of drawings
Fig. 1 is this practical structural representation;
Fig. 2 is this practical piston rod construction synoptic diagram.
Embodiment
The embodiment that this is practical: as shown in Figure 1, the formation of this practicality mainly is made up of tubular shaft 1, round nut 2, adjustment bolt 3, end cap 4, screw rod 5, nut 6, slide damper 7, spring assembly 8, cylinder body 9, spacing collar 10, piston 11, cylinder head 12, snubber 13, piston rod 14, installation screw rod 15, installation nut 16 etc.Slide damper 7 and spring assembly 8 outer being enclosed within on the tubular shaft 1, tubular shaft 1 is enclosed within on the piston rod 14, tubular shaft 1 left end is connected with round nut 2, end cap 4, cylinder body 9 and cylinder head 12 are connected to become integral body by screw rod 5 and nut 6, piston 11 is arranged on piston rod 14, snubber 13 is arranged on piston 11, the screw rod of installation 15 is arranged on cylinder head 12 and nut 16 is installed.
Piston rod construction as schematically shown in Figure 2.Because piston rod 14 right-hand members link to each other with mounting plate, be not easy to air inlet, so piston rod 14 left ends have been attacked internal thread M1 and had air inlet port d2, d4, pressurized gas enters the right chamber of cylinder by M1, d2 and d4, promote piston rod 14 certain distance that moves to left, piston rod 14 drives tubular shaft 1 and moves to left, and rotational circle nut 2 cuts off source of the gas up to compressing slide damper 7, tighten then and adjust bolt 3, thereby realize adjustment this device preliminary tension.The piston rod right-hand member has outside screw M2, is used to connect piston.
Claims (3)
1. integrated form pretension air cylinder device, it is characterized in that: slide damper (7) and spring assembly (8) are outer to be enclosed within on the tubular shaft (1), tubular shaft (1) is enclosed within on the piston rod (14), tubular shaft (1) left end is connected with round nut (2), end cap (4), cylinder body (9) and cylinder head (12) link into an integrated entity by screw rod (5) and nut (6), piston (11) is arranged on piston rod (14), snubber (13) is arranged on piston (11), installation screw rod (15) is arranged on cylinder head (12).
