Abstract

The utility model relates to construction equipment for a chimney. The platform of the construction equipment for a chimney is fixedly connected at a tower crane on the center. A hydraulic cylinder is arranged on the platform, and the climbing and folding expanding action of the hydraulic cylinder can be controlled. When the platform climbs along a tower body, a door frame is driven, and the door frame and a template are connected by a bolt and a nut. The template follows the platform to upwards slide along a cylinder wall. The weight of the platform of the construction equipment for a chimney is supported by the tower crane, which ensures that the platform can not float, incline, and twist, and thus, the quality of a chimney is markedly enhanced.

Description

Construction equipment for chimneys

The utility model relates to a kind of chimney construction equipment, belongs to the technical field of chimney construction machinery.

Present domestic steam power plant single-machine capacity constantly increases; Environment Protection Policy also proposes corresponding requirement to this; because of the structure of chimney also changes; the manual building method of the construction of chimney, silo one class building; spacious day more for a long time; all can not meet the demands with the construction speed aspect in quality, adopt plant equipment and technology to construct and also have many shortcomings, demand urgently improving.

Chimney construction equipment both domestic and external, mainly be to adopt sliding formwork and Ti Mo dual mode, carrying mould is divided into again and manually turns over mould and electric mould-lifting, be that uniform many hydraulic jack (quantity is decided on the chimney diameter) jack synchronously upwards promotes along the bar that climbs around chimney, drive template sliding lifting, penetrating beam by the width of cloth also rises platform, no matter be to put forward mould and slide plate mode, its common drawback is that platform easily drifts about, and reverses, tilt, make the physical dimension of chimney, the all difficult control of profile, during construction, personnel transport up and down with hopper, safety is relatively poor in the operation, platform adjust and the feeding time long, thereby speed of application is still slow, concrete to the platform afterwards by manually being pushed to working face, the operation number is more, and mechanization degree is poor.

The purpose of this utility model is the chimney construction device that a kind of novelty will be provided, and it can overcome above-mentioned shortcoming.

The purpose of this utility model is to realize like this, employing center tower crane, platform is by the body of the tower support, platform drives template system and can upwards climb along body of the tower, template can be thrown off with the concrete chimney barrel, the contracture oil cylinder is housed on the platform top, and the oil cylinder that vertically climbs is equipped with in the platform bottom, and the platform upper and lower all have last climbing frame and following climbing frame to be fixed on above the body of the tower, the leading screw screw also is housed, so that platform is moved up and down along the tower crane body of the tower, and its hydraulic system is to be received above the oil cylinder by oil pipe by the variable pump one way valve, and unnecessary oil returns fuel tank by safety valve and oil filter, body of the tower adopts and adheres to bar, with adhere to rod bearing, the servicing unit that adjusting nut is formed is supported between barrel and the body of the tower, make body of the tower keep correct center, the quality of chimney is guaranteed, and platform can not take place floating, tilts or reverses.Full peace is reliable in the operation.

Last climbing frame (10) down climbing frame (11) all is separately fixed at above the body of the tower, and platform upper and lower (10), (11) are along body of the tower (9) and move up and down, and is hung in up and down on the climbing frame by leading screw, and its step of climbing is as follows:

1, climb in platform top

Climb in platform top, the oil cylinder that vertically climbs is that fixed point promotes platform top (16) rising with platform bottom (21) just, radially contracture oil cylinder (17) also moves simultaneously, carry out the contracture action on request, the 4 rhizoid thick sticks of platform top (16) rise equal height by the via hole of last climbing frame with the nut on it.

2, platform top is fixed

To go up 4 nut screwing clampings on the climbing frame (10), platform top is hung on the climbing frame (10).

3, the platform bottom promotes

The oppositely logical oil of the oil cylinder (18) that vertically climbs is that fixed point is mentioned platform bottom (21) with platform top (16), and the bottom leading screw passes down the via hole of the frame that climbs simultaneously, makes nut rising same distance.

4, the platform bottom is fixed

To descend 4 nut screwing clampings on the climbing frame (11), platform bottom (21) is connected on down on the climbing frame (11), at this moment finish the action of once climbing, after the action of repeatedly climbing, leading screw on the climbing frame can unscrew last climbing frame top nut to the position of using up, and will go up climbing frame and rise to next fixed point and go up jack panel again after fixing and make down climbing frame continue as stated above to climb again with leading chain, fixing, so just can carry out the next one action of climbing.
