Description
Technical Field
The utility model relates to a steel strand wires counterpoint and wear a device belongs to bridge prestressing force construction technical field.
Background
In the process of bridge manufacturing and construction, a plurality of strands of steel strands need to be pulled through to exert prestress, namely prestress pulling. The prestress can improve the tensile capacity of concrete when bearing load, prevent or delay the appearance of crack, and increase the rigidity of structure, save steel and cement.
At present, the common stringing modes include a single stringing mode and an integral stringing mode. Wherein, the steel strands are threaded through the corrugated pipe one by a single threading machine. The mode not only consumes time, but also can not completely prevent the steel strand from being wound by penetrating the steel strand later and penetrating the steel strand first, and the problem that the stress of the steel strand is uneven during tensioning can also exist. Therefore, the mode of integral beam-through is generally adopted at present. The whole bundle penetrating adopts a pier head mode, outer ring steel wires of the steel strands are cut off, only one central steel wire is left, the central steel wires of the steel strands penetrate into the upset head, then the traction head and the traction sleeve are connected, and bundle penetrating is completed through the winch.
The whole bundle of stranded steel wires is generally braided before the whole bundle is penetrated. If the whole bundle is not woven, the steel strands can be wound in the corrugated pipe in the process of penetrating the multiple steel strands, so that the steel strands are stressed seriously unevenly during tensioning, and dangerous conditions such as steel strand slipping, steel strand breaking and even beam collapse can occur.
The chinese patent with application number 201811514245.0 discloses a method for threading a whole bundle of steel strands, which needs to use multiple coils of steel strands simultaneously to complete the threading of the whole bundle, and is inconvenient to use.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model provides a steel strand wires counterpoint and wear to restraint device, it only needs 1 rolls up steel strand wires and can accomplish whole bundle and compile and restraint, and service condition is more nimble.
In order to achieve the above object, the present invention provides the following technical solutions:
a steel strand alignment and strand pulling device comprises a workbench; the workbench is provided with a two-dimensional moving mechanism which moves in a vertical plane, and the two-dimensional moving mechanism is provided with a guide sleeve; the wire cutting machine is arranged on one side of the wire outlet end of the guide sleeve.
Further, the two-dimensional moving mechanism comprises an x-axis moving mechanism and a z-axis moving mechanism which are arranged in a nested mode.
Furthermore, the x-axis moving mechanism and the z-axis moving mechanism are both slide block mechanisms pushed by push rods.
Furthermore, the outlet end of the guide sleeve is a contracted taper.
Furthermore, the lifting mechanism is a rocker arm which is driven by a push rod to press and lift.
Furthermore, the device also comprises a combing and knitting device positioned outside the cutting machine, a plurality of through holes are formed in the combing and knitting device, and the combing and knitting device is fixed on the workbench through a support.
From the above description, the utility model discloses technical scheme's beneficial effect lies in:
1. the utility model discloses simple structure, low cost easily realizes.
2. The utility model discloses can alternate steel strand wires in different hole site departments respectively to cut steel strand wires through the dividing line machine, thereby only need 1 book steel strand wires can accomplish whole bundle and compile and restraint, service conditions is more nimble.

Detailed Description
In order to facilitate the understanding of the technical solutions of the present patent by those skilled in the art, the technical solutions of the present patent are further described in the following specific cases.
As shown in fig. 1, a steel strand alignment and strand pulling device includes a worktable 31; a two-dimensional moving mechanism 32 which moves in a vertical plane is arranged on the workbench 31, and a guide sleeve 33 is arranged on the two-dimensional moving mechanism 32; the wire cutting machine is characterized by further comprising a lifting mechanism 34, wherein a wire cutting machine 35 located on one side of the wire outlet end of the guide sleeve 33 is arranged on the lifting mechanism 34.
Further, as shown in fig. 2, the two-dimensional moving mechanism includes an x-axis moving mechanism 322 and a z-axis moving mechanism 321 which are nested, and both the x-axis moving mechanism and the z-axis moving mechanism can adopt a slider mechanism pushed by a push rod.
Furthermore, the wire outlet end of the guide sleeve is a contracted conical opening, so that the steel strand is aligned to the hole position.
Furthermore, the lifting mechanism is a rocker arm which is driven by a push rod to press and lift.
Furthermore, the device also comprises a combing and knitting device positioned outside the cutting machine, as shown in fig. 3, the combing and knitting device is provided with a plurality of through holes, and the combing and knitting device can be fixed on the workbench through a bracket.
When the steel strand combing machine is used, a steel strand 1 can penetrate into the guide sleeve 33 through the strand combing machine, the two-dimensional moving mechanism 32 sequentially aligns to each hole site of the combing and weaving device according to a set moving distance, the strand combing machine drives the steel strand to move when each pair of hole sites are aligned, the driving is stopped until the steel strand moves for a set length, the lifting mechanism drives the strand cutting machine to cut off the steel strand at the moment, then the two-dimensional moving mechanism aligns the guide sleeve to the next through hole, and the strand combing process is repeated. In order to ensure the whole bundle weaving effect, a guide pipe can be arranged at the outer side of the comb weaving device, and all the steel stranded wires which are penetrated and bundled are all sent into the guide pipe, so that the steel stranded wires are arranged neatly.
In a word, the utility model discloses can alternate steel strand wires in different hole site departments respectively to cut steel strand wires through the dividing line machine, thereby only need 1 coil of steel strand wires can accomplish whole bundle and compile and restraint, service conditions is more nimble.
It should be noted that the above embodiments are only specific examples of the implementation schemes of this patent, and do not cover all the implementation schemes of this patent, and therefore, the scope of protection of this patent cannot be considered as limited; all the implementations which belong to the same concept as the above cases or the combination of the above schemes are within the protection scope of the patent.
