Abstract

The utility model relates to a mechanical device for continuously producing prestressed concrete hollow plate in uniform speed, comprising a windlass, a delivering hopper, a vibrator, a vibrating framework, a vibrating core tube, a vibrating flat plate, a rolling drum, an insulating plate, etc. The front part of the utility model is designed into an open type and can pass through a constructing bar which is bound on a prestressing bar, the vibrator drives the vibrating core tube and the vibrating flat plate through the vibrating framework to continuously vibrate and press tightly concrete, and then a hole-forming core tube follows a machine to disengage from a hollow plate in uniform speed, thus finishing the moulding work. The utility model has the advantages of high efficiency and small ground occupation, saves reinforcing steel bars and can greatly improve the quality and the output of the hollow plate.

Description

Integral type drawing and moulding machine

The utility model relates to the concrete core slab manufacturing machine, and particularly the monoblock type drawing die forming machine belongs to precast concrete manufacturing machine field.

At present, long collimation method is produced prestressed reinforced concrete hollow slab, uses the inner-vibration type drawing-die machine usually.As: drawing die forming machine shakes in NZLM type 180, the 120 type series.Though the quality of the cored slab that it is produced is better than outer shake drawing die forming machine and single lead screw ex truding briquetting machine product; but yet depositing following deficiency: because mechanical floor space own is big; complex structure; so transition difficulty; distance should not be controlled between the cored slab; can't colligation construct muscle, cause during drawing core pipe that fish line crack appears in the cored slab surface, is having a strong impact on cored slab output and quality.

The purpose of this utility model is to provide a kind of monoblock type drawing die forming machine, and it has overcome the shortcoming that existing drawing die forming machine exists, for the output and the quality of concrete core slab provides assurance.

Of the present utility model being contemplated that: utilize core tube vibration principle; the drawing die forming machine front portion is designed to out the length that worn-out formula shortens vibration core tube; adopt a vibration source to drive vibration core tube and oscillating flat plate work; set up concrete and force cylinder; concrete is further imported in core pipe and the side form; vibration core tube and oscillating flat plate are closely knit with vibratory concrete, partition panel is installed between every cored slab can be guaranteed the cored slab spacing, affect drawing die forming machine to carry out continuous pouring along the track uniform motion by hoist engine.

Fig. 1 is the utility model schematic diagram.

Fig. 2 is the utility model structure chart.

Fig. 3 is the utility model vibration core tube structure chart.

Below in conjunction with Fig. 1,2,3 further narrate the utility model: it is by hoist engine (1), cast hopper (2), force cylinder (3), vibrator (4), frame tank bracket (5) shakes, oscillating flat plate (6), track (9), side form (11), fixed core pipe (12), partition panel (13), vibration core tube (14), pore-forming core pipe formations such as (15), vibration frame (5) is fixed on above the side form (11), its top is equipped with vibrator (4), vibration core tube (14) is fixedly connected with the preceding lock piece (8) of vibration frame (5), fixed core pipe (12) is fixed on side form (11) inboard, be with vibration core tube (14) on it, the front end of fixed core pipe (12) connects pore-forming core pipe (15), is installed with oscillating flat plate (6) below the vibration frame (5), when vibrator (4) drives vibration frame (5) vibration, vibration core tube (14) and oscillating flat plate (6) vibrate thereupon, and at first vibration core tube (14) is the concrete jolt ramming that pours into, the concrete compacted by jolting and oscillating flat plate (6) further pressurizes, finish concrete last vibrating compacting work, improve vibration efficiency.In addition, below vibration frame (5), force cylinder (3), be bearing in the top of side form (11) by bearing, the one end is connected with hoist engine (1) chain by drive, upward even hinge joint has 6-8 swing tooth plate (10) in the garden week of forcing cylinder (3), can amount to counterclockwise, when forcing cylinder (3) to rotate, forcing under vibration core tube (14) and oscillating flat plate (6), to be input into the part concrete under the drive of tooth plate (10), by oscillating flat plate (6) vibrating compacting, cast hopper (2) is installed in the front of vibration frame (5), in side form (11), hoist engine (1) is in side form (11) front with the concrete cast, and the traction entire machine is at the uniform velocity advanced, the utility model has also designed the supporting with it use of partition panel (13), its structure is a cuboid, and some openings garden groove (7) is arranged above, and slightly larger in diameter is in the diameter of vibration core tube (14), it is freely passed through, some through holes (16) are arranged at the bottom, and the cored slab steel wire is passed, and material is selected the rubber and plastic elastomeric material for use.

The utility model in use; at first steel wire stretching is finished; track and pedestal are fixed; according to the specification of producing cored slab partition panel is placed on the steel wire; adjust fixed size in orbit; give colligation structure muscle on the steel wire of every cored slab; the monoblock type drawing die forming machine is placed start in place on the track; import concrete continuously to vibration core tube by cast hopper; in the side form; force cylinder to rotate and further force the lead-in portion concrete; hoist engine traction this moment complete machine at the uniform velocity advances; vibrator drives vibration core tube by vibration frame; oscillating flat plate is constantly with the vibratory concrete compacting, and vibrating core tube edge vibration limit breaks away from cored slab, finishes the cored slab shaping work.

The utility model adopts 5 vibration core tubes in implementation process, fixed core pipe, pore-forming core pipe.Size shortens to 0.6 meter by 5 meters of original length, and the machine length overall shortens to 3 meters by 9 meters, and it has the vibration efficiency height, and floor space is little, saves reinforcing bar, can increase substantially characteristics such as the quality of cored slab and output.
