Description

Technical Field

[0001] The invention relates to the field of sleeper processing, in particular to a sleeper bolt feeder. Background Art

[0002] The sleeper, also known as the sleeper, is a type of railway accessory. The sleeper not only supports the rails, but also maintains the position of the rails, and also transfers the huge pressure transmitted by the rails to the roadbed. It must have a certain degree of flexibility and elasticity, and it cannot be too hard or too soft. When a train passes by, it can be deformed appropriately to buffer the pressure, but it must be restored to its original state as much as possible after the train passes.

[0003] In the assembly of cement sleepers, one of the steps is to insert the sleeper bolts from bottom to top. Due to the heavy sleepers, manual work is currently time-consuming and labor-intensive, and inefficient. Since sleeper bolts are always used in symmetrical pairs, if a feeder that can complete the insertion of two bolts at a time is developed, the efficiency can be greatly improved. Summary of the invention

[0004] The object of the present invention is to provide a sleeper bolt feeder.

[0005] The object of the present invention is achieved by the following means:

[0006] A sleeper bolt feeder comprises a vibrating plate for arranging bolts in a row and feeding them out one by one, a bolt cutting mechanism is arranged at the outlet of the vibrating plate, the bolt cutting mechanism comprises a cutting block, the cutting block is connected to a cutting cylinder, a clamping groove for clamping the bolt head is arranged at the cutting block facing the outlet of the vibrating plate; a clamping claw for clamping the lower part of the bolt is arranged below the clamping claw; a bolt turning mechanism is arranged on one side of the clamping claw, and the clamping claw is connected to a transverse cylinder for pushing the bolt to the bolt turning mechanism;

[0007] The bolt turning mechanism includes a turning shaft, on which two turning jaws are installed, and the turning shaft is connected to a rotary cylinder for rotating the turning shaft; a guide rail is provided at the bottom of the bolt turning mechanism, and a shift cylinder is provided on one side of the bolt turning mechanism. The shift cylinder pushes the bolt turning mechanism to move on the guide rail, so that the two turning jaws are aligned with the jaws of the bolt cutting mechanism in turn, and the two turning jaws are loaded;

[0008] A bolt transplanting and lifting mechanism is provided behind the bolt flipping mechanism. The bolt transplanting and lifting mechanism includes two bolt holes corresponding to the positions of the two flipping jaws on the flipping shaft. When the flipping shaft drives the flipping jaw to rotate 180°, the flipping jaw loosens the bolt, and the bolt falls into the bolt hole. Each of the two bolt holes is connected with a set of transplanting mechanism to send the bolt to the designated position.

[0009] Furthermore, the transplanting mechanism includes a lifting cylinder located below the bolt hole, the lifting cylinder is installed on the longitudinal linear module, and the longitudinal linear module is installed on the transverse linear module.

[0010] Furthermore, a clamping claw for clamping the bolt head is provided in the bolt hole.

DETAILED DESCRIPTION

[0018] The present invention is described in more detail below with reference to embodiments.

[0019] like Figure 1-1A sleeper bolt feeder comprises a vibration plate 2 for arranging bolts in a row and feeding them out one by one, a bolt cutting mechanism 4 is arranged at the outlet of the vibration plate, the bolt cutting mechanism comprises a cutting block 4-7, the cutting block is connected with a cutting cylinder 4-8, a clamping groove 4-6 for clamping the bolt head is arranged at the outlet of the vibration plate facing the cutting block; a clamping claw 4-1 for clamping the lower part of the bolt is arranged below the clamping claw; a bolt turning mechanism 5 is arranged on one side of the clamping claw, and the clamping claw is connected with a transverse cylinder 4-3 for pushing the bolt to the bolt turning mechanism;

[0020] The bolt turning mechanism comprises a turning shaft 5-7, on which two turning jaws 5-6 are mounted, and the turning shaft is connected to a rotary cylinder 5-3 for rotating the turning shaft; a guide rail 5-2 is provided at the bottom of the bolt turning mechanism, and a shift cylinder 5-9 is provided on one side of the bolt turning mechanism, and the shift cylinder pushes the bolt turning mechanism to move on the guide rail so that the two turning jaws are aligned with the jaws of the bolt cutting mechanism in turn, thereby completing the loading of the two turning jaws;

[0021] A bolt transfer and lifting mechanism 6 is provided behind the bolt flip mechanism. The bolt transfer and lifting mechanism includes two bolt holes 6-1 corresponding to the positions of the two flip clamps on the flip shaft. When the flip shaft drives the flip clamp to rotate 180°, the flip clamp loosens the bolt, and the bolt falls into the bolt hole. Each of the two bolt holes is connected to a set of transfer mechanisms to send the bolt to the designated position. The transfer mechanism includes a lifting cylinder 6-5 located below the bolt hole, and the lifting cylinder is installed on the longitudinal linear module 6-7, and the longitudinal linear module is installed on the transverse linear module 6-8.

[0022] The specific working process is that the sleeper bolts are arranged in order into the bolt cutting block through the vibration plate, the clamp drives the clamp block to clamp the bolts, and the cutting cylinder retracts. Then the traverse cylinder moves to the first flip clamp to clamp, the clamp is released, the traverse cylinder retracts, and the first bolt loading is completed. Then the shift cylinder extends, and the second bolt loading is completed according to the above process.

[0023] Then the flip axis rotates 180 degrees, the flip jaws loosen, and the bolt falls into the bolt hole. The jaws of the bolt hole clamp the bolt, and the two linear modules move to the specified position according to the program, and then the lifting cylinder lifts up, the jaws of the bolt hole loosen the bolt, and the loading is completed.
