Description

Precast concrete piece takes off die carrier

Technical Field

The utility model relates to a demoulding frame, in particular to a precast concrete block demoulding frame.

Background

A large amount of precast concrete is used in the highway construction process, the precast concrete is processed and formed in a precast yard, the stirred and mixed concrete is poured into a plastic mold during processing, and after the concrete is cured, hardened and solidified, the precast concrete blocks are required to be demolded, and although a plurality of formed or designed devices can realize automatic demolding of the precast concrete at present, the devices have complex general structures and are complete sets of devices, and the price is high; in addition, the size is huge, and a great deal of manpower, material resources and financial resources are required to be spent on carrying, installing and dismantling in order to match the construction of different highways; moreover, the devices cannot realize complete intelligent work, workers are required to perform positioning, control and the like, and the demolding speed of the devices is not faster than that of the workers. The existing demoulding of the precast concrete blocks is mainly achieved by the fact that after a worker integrally overturns a mould together with the precast concrete blocks by 180 degrees by means of self strength, the precast concrete blocks automatically fall off from the mould under the action of gravity, but the worker can consume more labor when the worker overturns and demoulds, and manual demoulding cannot be achieved when the precast concrete blocks are demoulded in a large scale.

Description of the embodiments

The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.

Embodiments of the utility model: the precast concrete piece takes off the die carrier, as shown in fig. 1-10, take off the die carrier 1 including square frame structure, take off die carrier 1 front end both sides vertical fixation has backup pad 2, the vertical mounting panel 3 that is fixed with in rear end both sides, 2 the lateral wall of mounting panel 3 all is provided with the back fulcrum bar 4 that outwards stretches out, it is all fixed to be provided with loop bar 5 on the left and right lateral wall of drawing of patterns frame 1, the sleeve 6 has been cup jointed in the rotation on the loop bar 5, fixedly connected with pinch bar 7 on the sleeve 6, pinch bar 7 backward extends and is located the below of back fulcrum bar 4, 2 the other end of pinch bar 7 is through horizontal pole 8 fixed connection, take off die carrier 1 bottom surface front side is provided with baffle 9, the left and right both sides of drawing of patterns frame 1 bottom surface are provided with L type cardboard 10, the L type cardboard 10 opening in both sides sets up in opposite directions.

When the utility model is used, firstly, as shown in fig. 5, a precast concrete block to be demolded is positioned in a mold 14, the mold 14 is of a plastic frame structure, the top of the mold 14 is provided with a flange plate 15 extending outwards, the utility model is placed right in front of the mold 14, the rear end of the utility model is opposite to the front end of the mold 14, the cross rod 8 is pulled to enable the whole demolding frame to move towards the direction of the mold 14, finally, the mold 14 enters the bottom of the demolding frame 1, the flange plate 15 of the mold 14 is clamped between an L-shaped clamping plate 10 and the bottom of the demolding frame 1, and when the front end of the mold 14 is contacted with a baffle plate 9 at the front end of the demolding frame 1, the mold 14 is completely clamped into the demolding frame 1, and the clamping state is shown in fig. 6 and 7. Then the cross bar 8 is lifted upwards in an inclined way, the cross bar 8 is contacted with the rear supporting point rod 4, and the demoulding frame 1 is lifted upwards and rotated by 90 degrees by taking the rear supporting point rod 4 as a supporting point, so that the state shown in fig. 8 is obtained. Then, the worker moves to the front of the demoulding frame 1 and pulls the cross rod 8 downwards in an inclined way, so that the demoulding frame 1 is continuously turned over by 90 degrees, the whole mould 14 is integrally turned over by 180 degrees, and the precast concrete blocks in the mould 14 automatically fall out of the mould 14 under the action of self gravity, so that demoulding is completed.

The outer side walls of the lower ends of the 2 support plates 2 are respectively provided with a front supporting point rod 11 extending outwards, the precast concrete blocks in the mould 14 can automatically fall out of the mould 14 under the action of self gravity to finish demoulding, then as shown in fig. 9, the pry bar 7 is rotated to enable the pry bar 7 to be in contact with the front supporting point rods 11, one front supporting point rod 11 serves as a supporting point, then the cross rod 8 is obliquely pressed downwards, the mould 14 and the demoulding frame 1 are reversely rotated by 90 degrees under the action of pressure to form a state shown in fig. 10, and at the moment, the mould 14 can be conveniently pulled out of the demoulding frame 1, so that the whole process is completely finished.

The rear side wall of the demoulding frame 1 is provided with a movable baffle plate inserting hole 12, and a movable baffle plate 13 can be inserted into the movable baffle plate inserting hole 12. In the process of switching from fig. 8 to fig. 9, in order to avoid the die 14 from sliding out of the knock out frame 1 under the forward inertia in the process of rotating the die 14 and the knock out frame 1 obliquely downward, when the die 14 and the knock out frame 1 are rotated to the state shown in fig. 8, the flapper 13 is inserted into the flapper insertion hole 12, and then the die 14 and the knock out frame 1 are obliquely turned over obliquely downward, and the die 14 cannot slide out of the knock out frame 1 due to the blocking of the flapper 13.

When the prying bar 7 is in contact with the rear supporting point bar 4, the rear supporting point bar 4 is used as a demarcation point, the rear end length is longer than the front end length, and because the rear end length is longer than the front end length, according to the lever principle, a worker can lift or overturn the die 14 and the demoulding frame 1 filled with the precast concrete blocks only by applying small force.
