Description

Technical Field

[0001] The utility model relates to the technical field of track processing equipment, in particular to a railway track insulating splint bolt ejection device. Background Art

[0002] When the railway rails are joined together, in order to ensure the track joining requirements, plywood is used to connect the waists on both sides of the joints. In order to meet the insulation performance requirements, glued insulating plywood is used. According to the "Technical Conditions for Glued Insulated Joints of Railway Rails" TB / T2975-2010, adhesive is used to bond the glued insulating plywood to the rails at the construction site and fasten them with high-strength bolts. Because the adhesive is very strong, it is very difficult to remove.

[0003] During train operation, the insulating splints bear the various loads borne by the rails, so the splints are prone to insulation failure or cracks at the rail joints. Splint damage is more likely to occur at turnouts and curved sections due to the large lateral forces borne by the rails. When the insulating splint is damaged, it must be replaced immediately.

[0004] When disassembling the splint, the high-strength fastening bolts are firmly glued, so the traditional replacement method is to use oxygen, acetylene flame heating or special heating equipment to heat the bolts, and then use a steel chisel or a sledgehammer to smash them. The replacement time is long, the labor intensity is high, and the risk of fire on site is high, and the heating temperature is difficult to effectively control. Utility Model Content

[0031] The support plate 3 is provided with a hook 34 for hooking and fitting onto the right-angle edge of one side of the insulating clamping plate 2 to facilitate operation.

[0032] A plurality of adjusting bolts 33 are provided in the middle of the top of the support plate 3. The support plate 3 is fixed to the rail 1 by adjusting the bolts 33, so that the support can be quickly placed and leveled to keep the ejection device level so that the push rod and the bolt are on the same axis.

[0033] The pushing rod 36 and the bolt ejecting rod 37 are connected by a thread, which is convenient for disassembling and replacing the bolt ejecting rod 37. After the bolt 22 is ejected, a larger ejecting head can be replaced to completely eject the remaining insulating sleeve 23 remaining in the hole. The ejecting head has its own thread and can be easily disassembled and assembled.

[0034] A guide cylinder 32 is provided between the bolt ejector rod 37 and the bolt 22 for quickly aligning the axes of the bolt 22 and the bolt ejector rod 37 under non-visual conditions, so that the two can be quickly positioned and connected and prevent slippage and deviation.

[0035] The support plate 3 is an inverted U-shaped structure, which can just cover the rail 1 and the insulating clamping plate 2.

[0036] An arc-shaped notch 35 is formed on one side of the support plate 3 to reserve space for the bolt 22 and the insulating sleeve 23 during the ejection process.

The positioning assembly 38 comprises two L-shaped plates connected at their tops by a horizontal connecting plate. The edges of the two L-shaped plates of the positioning assembly 38 provide horizontal positioning. During the ejection process, they hook onto the bottom edges of the two rails to prevent force imbalance and pitch displacement during the ejection process.

[0045] Example 4

[0046] See Figure 9 As shown, the positioning assembly 38 hooks the upper end of the rail 1, and the hook 34 hooks the lower end of the rail 1; the rest of the structure is the same as that of embodiment 1;

[0047] The working principle of the present invention is as follows: the support plate 3 is placed on the rail 1 and the insulating splint 2, the hook 34 is hooked and fitted on the right-angle edge of one side of the insulating splint 2, and is locked by adjusting the bolt 33, and then the hydraulic cylinder 31 is started to drive the push rod 36 and the bolt ejector rod 37 to move to eject the bolt 22. After the bolt 22 is ejected, a larger ejector head can be replaced to eject all the remaining insulating sleeve 23 remaining in the hole. The ejector head has its own thread and can be easily disassembled and assembled.
