Abstract
The utility model relates to a hole-forming mode switching device for a sleeper mold, which is connected to a III a-type sleeper mold and comprises a cylinder and a base tray arranged at the bottom of the cylinder, wherein a vertical sleeve positioning bolt hole is formed in the center of the cylinder; the cylinder passes through a III a-type sleeper bottom mold and is inserted in a rail groove plate hole of a III a-type sleeper groove plate; at least three bolt holes of the base tray are distributed uniformly on the base tray; and the base tray is detachably connected with the III a-type sleeper bottom mold through bolts inserted in the bolt holes of the base tray. The switching device can realize the compatibility of the III a-type sleeper mold and a III c-type sleeper mold, that is, III c-type sleepers can be produced by the III a-type sleeper mold, so that the production cost of the sleeper is reduced, and the utilization ratio of the mold is improved; and meanwhile, the raw materials of manufacturing a III c-type sleeper mold can be greatly saved, and the low-carbon environmental protection requirement can be met.
Description
Technical field
The utility model relates to the prestressed reinforced concrete tie production field, particularly a kind of conversion equipment that is installed on the prestressed reinforced concrete tie mould.
Background technology
Traditional III a type sleeper adopts pre-buried rubber bar pore-forming, traditional III c type sleeper adopts the service sleeve pore-forming, the appearance and size of the sleeper of two kinds of models is identical, but because the pore-forming mode difference of two kinds of sleepers, so need use special III a type sleeper mould during production III a type sleeper, production III c type sleeper need use special III c type sleeper mould, and this will increase very big production cost, waste a lot of means of production, do not meet the requirement of low-carbon environment-friendly.
The utility model content
The purpose of this utility model provides a kind of sleeper mould pore-forming mode conversion equipment, the technical problem that solve III c type sleeper production cost height, can waste a lot of means of production.
For achieving the above object, the utility model adopts following technical scheme: a kind of sleeper mould pore-forming mode conversion equipment, it is characterized in that: be connected on the III a type sleeper mould, comprise cylinder and the collet that is positioned at the cylinder bottom, described cylindrical center has vertical sleeve pipe positioning bolt hole, cylinder passes III a type sleeper end template, is inserted in the rail frid hole of III a type sleeper rail frid, be evenly equipped with at least three collet bolts hole on the described collet, collet removably connects by bolt and the III a type sleeper end template that is through in the collet bolt hole.
Described cylindrical external diameter is less than the diameter in the rail frid hole on the III a type sleeper rail frid, the diameter of described sleeve pipe positioning bolt hole is less than the internal diameter of III c type sleeper specialized barrel, the upper surface of described collet has the gradient, and the gradient of the upper surface of collet is corresponding with the gradient of the bottom surface of III a type sleeper end template.
The diameter of described sleeve pipe positioning bolt hole is than the little 0.1mm of internal diameter of III c type sleeper specialized barrel.
The gradient of the upper surface of described collet is 1:40.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model is a kind of conversion equipment, can realize the general of III a type sleeper mould and III c type pillow mould, promptly utilize III a type sleeper mould production III c type sleeper, that is to say after the utility model, just need not to make specially again III c type sleeper mould, this has just reduced the production cost of sleeper naturally, improved the utilization rate of mould, save simultaneously the raw material of making III c type sleeper mould greatly, met the requirement of low-carbon environment-friendly.
The utility model has overcome the restriction of casing pipe hole forming mode to sleeper mould, as long as the appearance and size of sleeper is identical, III a type sleeper mould can both adopt pre-buried rubber bar pore-forming to produce III a type sleeper, also can adopt the service sleeve pore-forming to produce III c type sleeper by the utility model is installed.The utility model structure is very simple, and manufacturing cost is very low, and the raw material that consumed are are seldom installed and used all very conveniently, meet the development trend of low-carbon environment-friendly, can be widely used in the prestressed reinforced concrete tie production field.

The specific embodiment
Embodiment is referring to shown in Fig. 1-6, this sleeper mould pore-forming mode conversion equipment, be connected on the III a type sleeper mould, comprise cylinder 1 and the collet 3 that is positioned at the cylinder bottom, the center of described cylinder 1 has vertical sleeve pipe positioning bolt hole 2, cylinder 1 passes III a type sleeper end template 7, is inserted in the rail frid hole 5 of III a type sleeper rail frid 6, be evenly equipped with at least three collet bolts hole 4 on the described collet 3, collet 3 removably connects by bolt and the III a type sleeper end template 7 that is through in the collet bolt hole 4; The external diameter of described cylinder 1 is slightly less than the diameter in the rail frid hole 5 on the III a type sleeper rail frid 6, the diameter of described sleeve pipe positioning bolt hole 2 is less than the internal diameter of III c type sleeper specialized barrel, the upper surface of described collet 3 has the gradient, and the gradient of the upper surface of collet 3 is corresponding with the gradient of the bottom surface of III a type sleeper end template 7.
In the present embodiment, the diameter of described sleeve pipe positioning bolt hole 2 is than the little 0.1mm of internal diameter of III c type sleeper specialized barrel, and the gradient of the upper surface of described collet 3 is 1:40.In addition, because rail cant is 1:40, for accurately guaranteeing rail cant, the highly a little higher than III a type of manufacturing of the present utility model sleeper rail frid 6 is polished the utility model concordant with III a type sleeper rail frid 6 after installing.
During use, cylinder 1 can be worn from the bottom to top to rail frid hole 5, the bottom surface of the upper surface of collet 3 and III a type sleeper end template 7 is closely connected, then by collet bolt hole 4, with the utility model thread connection on III a type sleeper rail frid 6 and III a type sleeper end template 7.
In the present embodiment, the internal diameter of III c type sleeper specialized barrel is 25mm, and III a type sleeper mould is 45mm at the opening diameter at rail frid rubber bar place.When production III c type sleeper, on III a type sleeper mould, the utility model is installed; When production III a type sleeper, remove the utility model, on III a type sleeper mould, rubber bar is installed.
