Abstract
The invention discloses a preloaded cylinder device. A hollow shaft (1) is sleeved on a piston rod (13). A sliding stop (2) and a spring assembly (7) are respectively sleeved on the hollow shaft (1). The sliding stop (2) is respectively connected with a circular nut (3) and an end cap (4) through screw thread. The end cap (4), a cylinder body (8) and a cylinder cap (11) are connected with a nut (6) through a screw rod (5) so as to form an integral body. A piston (10) is connected with the piston rod (13). A buffer (12) is arranged on the transverse plane of the piston (10). A spacing sleeve (9) is mounted on the transverse plane inside the end cap (4). A bolt (14) and an installation nut (15) are disposed on the transverse plane outside the cylinder cap (11). The device provided by the invention is fixed with an installing plate. The invention has advantages of compact structure and large and adjustable preloaded force. In addition, compaction of an aluminum guide rod and a bus or stretching of a clamp of the aluminum guide rod can be reliably realized.
Description
Technical field
The present invention relates to a kind of aluminum electrolysis industry makes aluminium guide bar be adjacent to bus in the operating process of positive bar lift frame or makes the open PWR PLT of anchor clamps on the positive bar lift frame.
Background technology
The effect of the positive bar lift frame that potroom uses is to make the cylinder ventilation on it promote the anchor clamps on the piston rod drive positive bar lift frame; Make aluminium guide bar compress bus; Clamp the capsule anchor clamps of aluminium guide bar then with TO, 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, accomplish bus and promote action through return spring.Perhaps die if positive bar lift frame supply gas pressure in operating process is not enough, the bad or disengaging of then fitting between aluminium guide bar and the bus, this will cause ordinary production and have a strong impact on.
Summary of the invention
The technical problem that the present invention will solve is; A kind of pretension air cylinder device is provided; This device utilizes the preliminary tension of PWR PLT medi-spring self to make aluminium guide bar be adjacent to bus through the anchor clamps in the positive bar lift frame when the positive bar lift frame is operated, and spurs through cylinder air feed back piston bar and realizes opening of anchor clamps on the positive bar lift frame; Fit bad between aluminium guide bar that prior art exists and the bus or break away to overcome, ordinary production is caused to have a strong impact on wait deficiency.
The present invention adopts following technical scheme: hollow shaft sleeve is on piston rod; Slide damper, spring assembly are enclosed within on the tubular shaft respectively; Slide damper is connected with acorn nut, end cap respectively through screw thread, and end cap, cylinder body and cylinder head connect into integral body through screw rod and nut, and piston is connected with piston rod.
Be provided with snubber in piston end face.
Inboard end face at end cap is provided with spacing collar.
End face is provided with bolt in the outside of cylinder head.
Compact construction of the present invention, preliminary tension is big and adjustable, can reliably realize compressing of aluminium guide bar and bus or opening of aluminium guide bar anchor clamps.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiments of the invention: as shown in Figure 1; Formation of the present invention mainly is made up of tubular shaft 1, slide damper 2, acorn nut 3, end cap 4, screw rod 5, nut 6, spring assembly 7, cylinder body 8, spacing collar 9, piston 10, cylinder head 11, snubber 12, piston rod 13, installation screw rod 14, installation nut 15 etc.
Tubular shaft 1 is enclosed within on the piston rod 13; Slide damper 2, spring assembly 7 are enclosed within respectively on the tubular shaft 1; Slide damper 2 is connected with acorn nut 3, end cap 4 respectively through screw thread, and end cap 4, cylinder body 8 and cylinder head 11 connect into integral body through screw rod 5 and nut 6, and piston 10 is connected with piston rod 13.
End face at piston 10 is provided with snubber 12.
Inboard end face at end cap 4 is provided with spacing collar 9.
End face is provided with bolt 14 in the outside of cylinder head 11.
Constructional feature of the present invention is following: tubular shaft 1 and piston rod 13 assemblings; Slide damper 2 open core type external thread structures not only can slide on tubular shaft 1, play the effect of compression spring and guiding; And can with the screw-internal thread fit of end cap 4; The height of fixing spring group 7, spring assembly 7 and tubular shaft 1 assembling, acorn nut 3 cooperates with the outside screw of slide damper 2; Play the effect of locking slide damper 2, end cap 4, cylinder body 8 and cylinder head 11 are an integral body through screw rod 5 and nut 6 with sealings such as spring assembly 7, pistons 10.Spacing collar 9 plays the effect of travel limit, and snubber 12 is avoided piston 10 and cylinder head 11 rigid shocks.Screw rod 14 is installed to be fixed this device and mounting plate with installation nut 15.Because piston rod 13 right-hand members link to each other with mounting plate, are not easy to air inlet, so piston rod 13 left ends have been attacked IT and had air inlet port, pressurized gas gets into the right chamber of cylinder through piston rod 13 left ends.Slide damper 2 right-hand members are the hex hd structure, rotational slide baffle plate 2, and the height of adjustment spring assembly 7, thus reach adjustment preliminary tension size.
