Description

Accurate positioning and clamping device for steel bar prefabricated part

Technical Field

The utility model relates to a reinforcing bar prefab steps up the device, specifically is reinforcing bar prefab accurate positioning steps up the device, belongs to road bridge construction field.

Background

Along with the rapid development of national infrastructure, more strict requirements are provided for engineering quality and production safety, the automation degree of construction equipment is higher and higher, particularly, the requirement on precision clamping control in a steel bar prefabricated part is stricter, and high-grade numerical control automation equipment must be provided with a high-precision mechanical clamp so as to effectively improve the engineering quality of construction. The clamping device used in the existing steel bar prefabricated part processing industry is basically a through hole type clamp, and the through hole type clamp is characterized in that an inner hole is larger than the diameter of a steel bar, the steel bar must penetrate through the hole in construction, and then a staring wire is used for staring and fastening the steel bar for fixing. At present, the steel bar joints are connected by the sleeve for the mantle fiber, if the manufacture of the hooping in the pile foundation cage mostly adopts the traditional manufacture mode, the construction quality mainly depends on the operation skill and experience, and because the number of the steel bars on the circumference of the steel bar cage is large, the left and right deviation is large, the butt joint of two or more sections of steel bar cages is difficult, the work flow of subsequent hoisting equipment is directly influenced, the construction time is also prolonged, the construction cost is increased, and the manpower resource is wasted. At present, a reinforcing steel bar accurate positioning and clamping device which is simple in operation and reasonable in structure is not found in the construction of reinforcing steel bar prefabricated members.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming present reinforcing bar prefab and step up the coarse problem in location in the course of working to a reinforcing bar prefab accurate positioning step up device is disclosed. The technical scheme of the utility model as follows:

the fixed disc and the adjusting disc are respectively composed of two semicircles with inner holes, the fixed disc is sleeved in the adjusting disc through screw threads, a plurality of hinge plates are equally arranged on the outer edge of the fixed disc and are respectively hinged with a plurality of tightening claws through hinge shafts, the hinge plates on the outer edge of the fixed disc are 30-60 degrees at the joint of the circumferential surface and the two semicircles, the adjusting disc is a step-shaped disc, the outer edge of a large diameter simultaneously tightly pushes the tightening claws, one side of the outer edge of a small diameter is hinged through connecting pins, the other side of the outer edge of the small diameter is fixed through tightening bolts, and one side of the fixed disc is.

The utility model discloses rational in infrastructure, accord with mechanical principle, mechanical properties is stable, and is easy and simple to handle, and the security performance is high, and stability is reliable, and the location is accurate, steps up fastly, can look for the center automatically when stepping up the reinforcing bar, as long as rotate the adjusting disk top tightly step up the claw and will make reinforcing bar automatic positioning step up, reach a reinforcing bar prefab accurate positioning step up device that accords with quality safety requirement.

The reference numerals are explained below:

the device comprises a fixed disc 1, an adjusting disc 2, a hinge plate 3, a hinge shaft 4, a clamping claw 5, a connecting pin 6, a tightening bolt 7, a fixed plate 8 and a steel bar 9.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings, but the present invention is not limited to the embodiments:

the fixed disk 1 and the adjusting disk 2 are respectively composed of two semicircles with inner holes, the fixed disk 1 is sleeved in the adjusting disk 2 through screw threads, four hinge plates 3 are arranged on the outer edge of the fixed disk 1 in equal parts and are respectively hinged with four clamping claws 5 through hinge shafts 4, the hinge plates 3 on the outer edge of the fixed disk 1 are 45 degrees at the joint of the circumferential surface and the two semicircles, the adjusting disk 2 is a step-shaped disk, the large-diameter outer edge simultaneously tightly pushes the clamping claws 5, one side of the small-diameter outer edge is hinged through connecting pins 6, the other side of the small-diameter outer edge is fixed through tightening bolts 7, and one side of the fixed disk 1 is connected with. During the use, at first will through the fixed plate the utility model discloses it is fixed with the workstation, then loosen the tightening bolt, two semicircles that make fixed disk and adjustment disk open around the hinge, the tightening claw also opens simultaneously, place the hole of fixed disk with the reinforcing bar, then fold two semicircles of fixed disk and adjustment disk around the hinge, tighten the tightening bolt, it is rotatory left or right to rotate the adjustment disk, the tightening claw is withstood simultaneously in adjustment disk major diameter outer fringe, the tightening claw uses the connecting pin to prize as the center and makes all tightening claw other ends press to the reinforcing bar in the centre of a circle, make reinforcing bar center accurate positioning and tighten, when treating that the prefab preparation accomplishes the back and dismantle the reinforcing bar, rotatory adjustment disk opposite order.
