Description

Air duct frame device for producing all-steel radial tire

Technical Field

The utility model relates to a calendering stator production facility field especially involves the tuber pipe fixing device of calendering stator production usefulness, specifically indicates a tuber pipe frame device that production all-steel radial tire was used.

Background

The last spindle in-process when the calendering production, need make a round trip to pull the tuber pipe, make pneumatic line hang the walking, because the whole spiral that is of tuber pipe, when the installation, usually with the tuber pipe around on the steel wire to avoid the tuber pipe to appear excessively buckling and lead to ventilating and block. However, because the air pipe is in direct contact with the steel wire, after the air pipe is used for a long time, the air pipe is damaged by friction, air leakage is caused, once the air pipe leaks air, the pneumatic travelling crane can automatically fall down, and industrial accidents are easily caused.

Disclosure of Invention

The utility model discloses to prior art's not enough, provide an air duct frame device that production all-steel radial tire used, effectively avoided the problem of leaking out that tuber pipe and steel wire friction lead to.

The utility model discloses a through following technical scheme realizes, provide an air duct frame device that production all-steel radial tire used, establish a plurality of slip joint rings on the direction steel wire including the cover to and along radially wearing to establish the spliced pole on the slip joint ring rampart, the one end that the spliced pole stretches out the slip joint ring is equipped with tuber pipe clamping device.

This scheme passes through tuber pipe clamping device centre gripping tuber pipe, through the slip joint of slip joint ring and direction steel wire, when pulling the tuber pipe, the slip joint ring removes thereupon, has both formed the hanging support to the tuber pipe, has avoided producing the friction between tuber pipe and the direction steel wire simultaneously, through the setting of connector, has realized being fixed in the tuber pipe and has slipped the ring outside, further prevents that tuber pipe and steel wire from producing the friction wearing and tearing.

Preferably, the air pipe clamping device comprises two elastic pieces provided with arc sections, the arcs of the two elastic pieces are oppositely arranged, and the upper ends of the elastic pieces are inserted and fixed on the connecting columns. This tuber pipe clamping device who optimizes the scheme utilizes the shell fragment to carry out the centre gripping to the tuber pipe fixed, simple structure, and it is convenient to the installation and the dismantlement of tuber pipe, and the preparation degree of difficulty is little moreover, and is with low costs.

Preferably, the lower end of the connecting column is provided with a clamping notch extending along the axial direction, the upper end of each elastic sheet is fixed in the clamping notch through a bolt, and the width of the clamping notch is matched with the sum of the thicknesses of the two elastic sheets. This optimization scheme makes things convenient for the installation of shell fragment fixed through setting up the centre gripping opening, makes the operation more convenient.

Preferably, the connecting column through hole on the annular wall of the sliding connection ring is a long hole extending along the circumferential direction. This optimization scheme sets up to the slot hole through passing the spliced pole, makes things convenient for the spliced pole to remove along circumference, realizes the adjustment to tuber pipe spiral shape fixed position, also makes the spliced pole take place the displacement of certain range when receiving the thrust of tuber pipe, avoids the tuber pipe excessively to buckle.

Preferably, the inner wall of the sliding connection ring is fixedly connected with a supporting plate which is arranged opposite to the connecting column along the diameter direction, and the supporting plate and the arc top of the sliding connection ring form a sliding hole for the guide steel wire to pass through. This optimization scheme is through setting up the layer board, forms the slide opening that supplies the direction steel wire to pass at the top of slip ring inner wall, has reduced the range that produces relative displacement between slip ring and the direction steel wire to reduce the jump of slip ring under the tuber pipe effort, avoided the tuber pipe to be close to the steel wire simultaneously.

The utility model has the advantages that: through the setting of slip ring sum connecting post, both hung the support to the tuber pipe, avoided twining into the knot that dies, avoided tuber pipe and direction steel wire to produce the friction and the tuber pipe that leads to leaks out simultaneously again to the safe operation of pneumatic line hanging has been guaranteed.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in fig. 1, the air duct frame device for producing all-steel radial tires comprises a plurality of sliding rings 1 sleeved on guide steel wires and connecting columns 4 radially penetrating through the annular walls of the sliding rings, through holes for the connecting columns to pass through are formed in the annular walls of the sliding rings, a limiting table 3 is fixedly arranged at one end, located in the sliding rings, of the connecting columns, the diameter of the limiting table is larger than the width of the through holes, and therefore the connecting columns are prevented from falling off. This embodiment is for realizing the spliced pole and moving at certain range under the tuber pipe effect, establishes the spliced pole on the sliding connection rampart through the hole into the slot hole 6 that extends along circumference, and the extension length of slot hole is 1/3~1/2 of sliding connection rampart girth, has both guaranteed the spliced pole and has made spacing platform lose limiting displacement along circumference by avoiding leading to the pore wall to warp because the slot hole overlength.

The one end that the spliced pole stretches out the slip ring is equipped with tuber pipe clamping device, and is concrete, and the tuber pipe clamping device of this embodiment includes two shell fragments 5 that are equipped with the segmental arc, and the arc of two shell fragments sets up relatively, and the upper end of shell fragment is inserted and is established and fix on the spliced pole, and during the installation tuber pipe, break open the uniform distance with two shell fragments off with the fingers and thumb, put into the segmental arc department of shell fragment with square pipe, utilize the resilience of shell fragment to press from both sides the tuber.

For simplifying the structure, this embodiment is seted up at the lower extreme of spliced pole along the upwards centre gripping opening that extends of axial, and the upper end of shell fragment is fixed in the centre gripping opening through the bolt, and the width of centre gripping opening and the thickness sum adaptation of two shell fragments. Through setting up the centre gripping opening, can insert the shell fragment in the past, back, three direction down, it is more convenient to the installation of tuber pipe, and the accessible saw bit cutting of centre gripping opening forms, and the processing degree of difficulty is little.

The inner wall of the sliding connection ring is fixedly connected with a supporting plate 2 which is arranged opposite to the connecting column along the diameter direction, and the supporting plate and the arc top of the sliding connection ring form a sliding hole for the guide steel wire to pass through. By arranging the supporting plate, the sliding connection ring is prevented from jumping up and down.
