Technical Field

[0001] This utility model belongs to the field of track slabs, and in particular relates to a tooling for cleaning the edges of track slab anchor holes. Background Technology

[0002] During the production of track slabs, the forming quality of the anchor holes directly affects the subsequent laying and performance of the track slabs. Typically, after the track slabs are cast, burrs will form around the anchor holes. If these burrs are not cleaned in time, they will affect the quality of the anchor sealing and the durability of the track slabs.

[0008] Furthermore, the C-shaped structure of the burr removal device consists of three line segments. The starting point of the lower segment is a fixed end, and the lower segment extends outward in a direction perpendicular to the axis of the positioning pin. The starting point of the middle segment starts from the end point of the lower segment, and the middle segment is inclined towards the positioning pin. The end point of the middle segment connects to the starting point of the upper segment, and the upper segment extends towards the positioning pin in a direction perpendicular to the axis of the positioning pin. There is a gap between the end point of the upper segment and the positioning pin.

[0009] Furthermore, the burr removal device is a steel wire, the lower end of which is wound around the middle section of the positioning pin.

[0010] Furthermore, it also includes an adjustment device, which includes two washers and two adjusting nuts fitted onto the middle section of the positioning pin, and the middle section of the positioning pin is provided with external threads;

[0011] The two washers clamp the fixed end of the flash cleaning device, and the two adjusting nuts are located on the outside of one washer, clamping the two washers in the middle.

[0012] Furthermore, the angle between the lower and middle sections of the burr removal device is 30-90°.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. In the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0023] like Figure 1 As shown, this utility model includes a positioning pin 1, a flattening device 2, and a burr removal device 3; the flattening device 2 is fixed to the top of the positioning pin 1, and the burr removal device 3 is installed in the middle section of the positioning pin 1.

[0024] The positioning pin 1 is a long column made of alloy steel;

[0025] The flat-head device 2 is a circular alloy steel flat head. The shape and size of the circular alloy steel flat head are consistent with the shape and size of the anchor hole of the target track plate. It is centered on the positioning pin and can fit tightly with specific parts of the track plate to achieve precise positioning. The flat head has a flat surface that matches the shape of the anchor hole after sealing, which can flatten the sealing mortar filling material in the anchor hole.

[0026] The burr removal device 3 is an alloy steel wire with a C-shaped structure composed of three segments, the lower end of which is wound around the middle section of the positioning pin 1. The lower end of the C-shaped structure is a fixed end, which is installed in the middle section of the positioning pin 1, and the upper end of the C-shaped structure is a free end. The starting point of the lower segment is the fixed end, and the lower segment extends outward in a direction perpendicular to the axis of the positioning pin 1. The starting point of the middle segment starts from the end point of the lower segment, and the middle segment is inclined towards the positioning pin. The end point of the middle segment connects to the starting point of the upper segment, and the upper segment extends towards the positioning pin 1 in a direction perpendicular to the axis of the positioning pin 1. There is a gap between the end point of the upper segment and the positioning pin 1. The angle between the lower segment and the middle segment of the burr removal device 3 is 30-90°. The lower segment and the middle segment, and the middle segment and the upper segment of the burr removal device 3 are transitioned by rounded corners. Its shape is adapted to the contour of the anchor hole.

[0027] The burr cleaning device and the finishing head device operate synchronously to clean the mortar overflowing from the anchor hole and the surrounding burrs.

[0028] It also includes an adjustment device, which includes two washers 4 and two adjusting nuts 5 fitted onto the middle section of the positioning pin 1, and the middle section of the positioning pin 1 is provided with external threads.

[0029] The two washers 3 clamp the fixed end of the flash removal device 3, and the two adjusting nuts 5 are respectively located on the outside of one of the washers 3, clamping the two washers 3 in the middle. The adjusting nuts can slide up and down along the external thread on the positioning pin 1. By adjusting the fixed end and the position of the adjusting device on the positioning pin, the position of the flash removal device can be adjusted up and down to fit the flat surface around the anchor hole of the track slab. The two pads are used to fix the flash removal device; by adjusting the two adjusting nuts, the up and down position of the flash removal device can be controlled to achieve a fit with the surface around the anchor hole.

[0030] The bottom end of the positioning pin 1 can be installed in the fixing hole of the electric auger drill bit. The main body of the positioning pin is installed at the position of the electric auger drill bit to realize the rotation finishing and edge cleaning operation.

[0031] After the anchor holes in the track slab are filled with sealing mortar, use this tool and electric auger to finish and clean the edges; the edge cleaning work is completed after cleaning up the overflowing mortar and the burrs around the anchor holes.

[0032] This invention enables the cleaning of anchor holes in track slabs, while solving the inconsistency in quality of manual cleaning, reducing the workload of personnel, and improving work efficiency and the consistency of edge finishing quality.
