Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sleeper repair, and particularly relates to a sleeper rail slot repair mould. BACKGROUND

[0002] Concrete sleepers are widely used in the field of rail transportation. The rail slot of the concrete sleeper is the part that bears the rail and directly bears the impact of the train load. Under the action of long-term high load, the rail slot part is prone to wear or crushing, causing track irregularity, which seriously affects the safety of train operation. In addition to replacing the sleeper, repairing the rail slot part is also a common and more economical solution.

[0003] However, due to the various sizes of sleepers, there is currently no special mould for repairing the rail slot of the sleeper. When repairing the rail slot, the repair mortar is directly filled into the damaged part by hand, which has the following disadvantages: after repairing the rail slot, the flatness decreases, and during the repair process, the mortar will flow down from both sides of the damaged rail slot and cannot remain on the rail slot, thereby affecting the repair quality. Therefore, there is an urgent need to develop a repair mould suitable for repairing rail slots of sleepers of different sizes for high-quality repair of the rail slot of the sleeper. UTILITY MODEL CONTENTS

[0004] The utility model aims at overcoming a series of defects caused by the lack of a mould for repairing the rail slot of the sleeper in the prior art, and provides a rail slot repair mould for the sleeper, which can be used for repairing rail slots of sleepers of different sizes.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A rail slot repair mould for a sleeper comprises two symmetrical clamping plates with adjustable inclination angles, at least one distance rod connecting the two clamping plates and having adjustable length, two support ear plates respectively arranged on both sides of the clamping plates and rotationally connected with the clamping plates, and a locking mechanism for locking the support ear plates and the corresponding clamping plates.

[0007] As a further technical scheme, the clamping plate comprises a mould plate, mounting plates arranged on both sides of the mould plate, overflow grooves opened at both ends of the mould plate, and a flow guide plate arranged outside the mould plate.

[0008] As a further technical scheme, the two ends of the distance rod are respectively hinged to the corresponding mounting plates through a pin shaft.

[0009] As a further technical scheme, the distance rod comprises a threaded sleeve, two screw rods respectively inserted into both ends of the threaded sleeve, and a hinge ring arranged at the other end of the screw rod and rotationally connected with the screw rod.

[0010] As a further technical solution, the hinge ring is sleeved on the first pin and rotatably connected to the first pin.

[0011] As a further technical solution, the two corresponding mounting plates are connected by at least one telescopic rod, with both ends of the telescopic rod hinged to the mounting plate respectively.

[0012] As a further technical solution, the telescopic rod includes a housing, a spring disposed within the housing, and connecting rods inserted at both ends of the housing and sliding along the housing. The connecting rods are hinged to the corresponding mounting plates via pins.

[0013] As a further technical solution, the mounting plate is provided with a mounting ear plate, and the supporting ear plate and the mounting ear plate are rotatably connected by a pin.

[0014] As a further technical solution, the support ear plate is provided with an arc-shaped sliding groove centered on the third pin.

[0015] As a further technical solution, the locking mechanism includes a screw hole provided on the mounting ear plate, a locking bolt provided in the screw hole, and one end of the locking bolt passing through the arc-shaped groove and being threadedly connected to the screw hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention fixes two mold plates on both sides of the sleeper, using the molds to cover the repair mortar, thus avoiding the problem of no mortar remaining on the rail bearing surface due to disordered mortar flow. At the same time, this invention also sets an overflow groove on the mold plate to guide the mortar to overflow in a regular manner, thereby avoiding the problem of uneven rail bearing surface caused by disordered mortar overflow.

[0018] The supporting ear plate of this utility model can be mounted on the sleeper during use to prevent the mold from sliding down.

[0019] This invention, by setting an angle-adjustable clamping plate and a length-adjustable spacer, enables the mold to be applicable to the repair of rail bearing grooves for sleepers of different sizes.

[0020] This utility model rotatably connects the clamping plate and the supporting ear plate and fixes them with a locking structure, thereby realizing the adjustable angle of the clamping plate. This utility model adjusts the distance between the two clamping plates by setting a telescopic rod and a fixed distance rod. The above two measures make the mold of this utility model applicable to sleepers of different sizes. Attached Figure Description
