Description
Technical Field
The utility model relates to a ballastless track plate manufacturing die, in particular to a ballastless track plate die middle hole forming die.
Background
The middle hole forming die of the ballastless track slab is an important component of a concrete ballastless track slab die. The prior ballastless track plate middle hole forming die divides a hole type surrounding frame into a plurality of sections, the multi-section hole type surrounding frame is fixed on a bottom plate of a track plate die one by one through bolts to form the middle hole forming die, and the middle hole forming die has the problems of troublesome combination and demolding of the forming die and poor die combination precision and positioning precision.
Disclosure of Invention
The utility model aims to solve the technical problems and provides a ballastless track plate die middle hole forming die.
In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a ballastless track board mould mesopore moulded die, includes two framework units, and two framework units are U type structure, and the both ends are articulated through the locating shaft and are combined into the combination framework, the framework unit on be equipped with a plurality of bolt holes that compress tightly, form the rectangle cavity in the middle of two framework units combination back, the rectangle cavity in be equipped with a plurality of tool to lock turnbuckles, the both ends of tool to lock turnbuckle articulated shaft and framework unit hinge connection respectively.
Furthermore, the corners of the frame body units are all arc-shaped structures.
Furthermore, the lock turnbuckle is provided with two lock turnbuckles.
Compared with the prior art, the utility model has the advantages that: the method has the characteristics of simple and convenient molding combination and demolding operation, and high combination precision and positioning precision of the molding die, and can effectively improve the production efficiency and the product quality of the track plate.
Drawings
FIG. 1 is a schematic structural view of a middle hole forming die of a ballastless track slab die.
As shown in the figure: 1. a frame unit; 2. positioning a shaft; 3. compressing the bolt hole; 4. a lock turnbuckle; 5. and a hinge shaft.
Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In the description of the present utility model, it should be noted that, unless explicitly stated and limited otherwise, the term "connected" should be interpreted broadly, and for example, it may be a fixed connection, a removable connection, or an integral connection; the specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The working principle of the utility model is as follows: as shown in figure 1, the forming die for the middle hole of the ballastless track plate is provided with four frame units 1 which are in round angle L shapes, the four frame units 1 which are in round angle L shapes are symmetrically arranged in pairs and are respectively hinged and combined into two U-shaped combined frames through two positioning shafts 2 which are arranged on symmetrical axes, the two U-shaped frame units are butt-jointed and combined into a round angle rectangular frame which is matched with the middle hole of the track plate through inclined end faces which are symmetrically arranged at the front end, compression bolt holes 3 are distributed on the round angle rectangular frame, lock turnbuckles 4 are respectively arranged at the U-shaped opening ends of each U-shaped combined frame, and two ends of each lock turnbuckle 4 are respectively hinged with the U-shaped combined frame through hinging shafts 5.
When the concrete pouring device is used, the two positioning shafts are matched with the two positioning holes arranged on the bottom plate of the track plate die to position, the compression bolt is used for fixing the forming die on the bottom plate of the track plate die through the compression bolt hole on the forming die, and then concrete forming pouring of the middle hole of the track plate can be carried out; during demolding, the compression bolt is firstly disassembled, and then the two lock turnbuckles are sequentially rotated, so that demolding can be completed.
The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
