Background
Sleepers, also known as crossties, are one type of railway accessory. The sleepers are required to support the rails, maintain the position of the rails, and transmit the large pressure transmitted by the rails to the track bed. It must have a certain flexibility and elasticity, be hard and soft. When the train passes by, it can be properly deformed to buffer pressure, but the train must be recovered as far as possible after passing. The double-block sleeper comprises two cement blocks for installing rails, and the two cement blocks are connected through a truss. The truss is formed by welding three steel bars, and the top steel bar is connected with the two welded steel bars through the S-shaped web bars. However, the deformation of the truss occurs in the welding process, and the deformation is inconsistent, so that the horizontal verticality of the truss is inconsistent, and the problems of leakage or non-hanging in the subsequent hooks are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sleeper mould release agent jar pressure boost system.
The purpose of the utility model is realized through the following ways:
a double-block type sleeper truss straightening device comprises a truss conveyor, wherein a carrying mechanism is arranged at the tail end of the truss conveyor and fixed on a support, the carrying mechanism comprises a lifting plate, and a grabbing claw is arranged below the lifting plate; the lifting plate is connected with a translation beam through a vertical motor, the translation beam is arranged above the bracket through a slide rail, and a translation driving mechanism is arranged on the translation beam and drives the translation beam to move along the slide rail;
a straightening die is arranged below the slide rail and comprises two straightening extrusion blocks which are oppositely arranged, the top of the truss to be straightened is downwards placed between the two straightening extrusion blocks, positioning grooves for clamping steel bars at the top of the truss are formed in the lower parts of the two straightening extrusion blocks, and abdicating grooves are formed in the welding points of the steel bars at the top of the straightening extrusion blocks; and under the action of external force, the two straightening extrusion blocks are matched to extrude and straighten the steel bars at the top of the truss.
Further, the straightening die is driven by a hydraulic cylinder;
furthermore, 4 grabbing claws are arranged at the four corners below the lifting plate, so that 2 trusses can be grabbed at one time; two straightening dies are also arranged in parallel, wherein the two straightening extrusion blocks positioned on the inner side are fixed extrusion blocks and are fixed on the die supporting seat; two straightening extrusion blocks positioned on the outer side are power extrusion blocks, and a plurality of air cylinders are arranged on the outer side of each power extrusion block; the bottom of the power extrusion block is provided with a guide rail.
Furthermore, the grabbing claw is driven by a clamping claw cylinder.
Further, the translation driving mechanism is an air cylinder.
Compared with the prior art, the utility model has the advantages that:
the die is adopted to straighten the truss, the die has high precision, the precision of straightening the truss can be guaranteed, the truss can meet the requirement, and the processes such as hooking on the next step are facilitated.

Detailed Description
The present invention will be described in more detail with reference to the following examples.
As shown in fig. 1-3, the double-block sleeper truss straightening device comprises a truss conveyor 1 for transporting trusses 2, wherein a carrying mechanism is arranged at the tail end of the truss conveyor 1 and fixed on a support, the carrying mechanism comprises a lifting plate, four grabbing claws 3 are arranged below the lifting plate, 2 trusses can be grabbed at one time, and the grabbing claws 3 are driven by a clamping claw cylinder 13; the lifting plate is connected with a translation beam 4 through a vertical motor 6 and a guide rail 5, the translation beam 4 is installed above the support through a slide rail, a translation driving cylinder 7 is installed on the translation beam, and the translation driving cylinder 7 drives the translation beam to move back and forth along the slide rail.
A straightening die is arranged below the slide rail, two straightening dies are arranged in parallel, and the two straightening extrusion blocks positioned on the inner side are fixed extrusion blocks 11 and are fixed on a die supporting seat 8; two straightening extrusion blocks positioned at the outer side are power extrusion blocks 10, and a plurality of hydraulic cylinders 9 are arranged at the outer side of the power extrusion blocks 10. The bottom of the power extrusion block is also provided with a guide rail 12.
The steel bar at the top of the truss 2 to be straightened is downwards placed between the two straightening extrusion blocks, the lower parts of the two straightening extrusion blocks are provided with positioning grooves for clamping the steel bar at the top of the truss 2, and the straightening extrusion blocks are provided with abdicating grooves at the welding points of the steel bar at the top; and under the action of the hydraulic cylinder, the two straightening extrusion blocks are matched to extrude and straighten the steel bars at the top of the truss.
The specific working process is as follows:
the truss is conveyed to the position below the grabbing claw through the truss conveyer, the vertical motor is started, the motor is stopped after the lowering height reaches a preset position, the clamping claw cylinder is started to tighten the truss, the vertical motor is started to lift the height, when the truss reaches the preset height, the motor stops, the translation driving cylinder is started to drive the lifting mechanism to transversely move under the action of the slide rail and move to the position above the straightening die, the translation driving cylinder stops, the vertical motor is started, by reducing the height, the truss is sent into the die cavity, the vertical motor is stopped, the hydraulic cylinder outside the die is started, the hydraulic push head pushes the power extrusion block to move to the fixed extrusion block under the guidance of the guide rail, when the die assembly of the die is completed, the hydraulic cylinder returns after keeping the pressure for a certain time, the hydraulic cylinder moves reversely to drive the die to open the die cavity, the vertical motor is started to move the truss to the next step through the lifting height, and the truss waits for the next process.
