DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, in Example 1, a railway rail bonding bolt ejection device includes a hook plate 1, a connecting plate 2 and an ejection bolt 3, wherein the top end of the connecting plate 2 is connected to the end of the hook plate 1 away from its hook head, the ejection bolt 3 is threadedly installed on the bottom end of the connecting plate 2, and the hook plate 1 is used to hang on the top of the rail.

[0025] When removing the rail bonding bolts, the hook plate 1 is put on the rail top from top to bottom. At this time, the connecting plate 2 and the hook heads of the hook plate 1 are distributed on the inner and outer sides of the rail. Then, the ejector bolt 3 is screwed in, and the inner end of the ejector bolt 3 abuts against the end of the rail bonding bolt, thereby directly ejecting the rail bonding bolt.

[0026] A sleeve 4 is provided on the side of the bottom end of the connecting plate 2 facing the rail, and the inner diameter of the sleeve 4 is matched with the outer diameter of the ejector bolt 3 .

[0027] Specifically, the sleeve 4 is slidably installed on the connecting plate 2. After the hook plate 1 is put on the rail top and before the ejector bolt 3 is screwed in, the sleeve 4 is first pushed inward so that the sleeve 4 is put on the end of the rail bonding bolt. Then, when the ejector bolt 3 is screwed in, the ejector bolt 3 passes through the sleeve 4 and abuts against the end of the rail bonding bolt. In this process, the sleeve 4 aligns the ejector bolt 3 with the rail bonding bolt and guides the ejection direction of the ejector bolt 3 to ensure that the ejector thread can stably eject the rail bonding bolt.

[0028] A hook 5 for clamping at the bottom of the rail top is provided on the side of the connecting plate 2 facing the rail, a spring 6 is provided between the hook 5 and the connecting plate 2, and the hook 5 can be extended and retracted on the connecting plate 2. When the hook plate 1 is put on the rail top, the hook 5 is clamped at the bottom of the rail top away from the hook head of the hook plate 1, and then, the hook plate 1 cooperates with the hook 5 to ensure that the ejection device is fixed on the rail as a whole and stably, further improving the ejection effect and stability of the rail bonding bolt.

[0029] Specifically, the hook 5 is slidably installed on the connecting plate 2 in a direction perpendicular to the connecting plate 2, and the outer end of the hook 5 is connected to the pull rod 7. When the hook plate 1 is put on the rail top, the hook 5 receives the pressure of the rail edge to compress the spring 6 and shrink into the connecting plate 2. When the hook plate 1 is put on the rail top, the hook 5 moves to the bottom of the rail top, and automatically extends and clamps at the bottom of the rail top under the action of the spring 6. After the rail bonding bolts are ejected, when the ejection device is removed from the rail as a whole, the pull rod 7 is pulled outward to make the hook 5 detach from the bottom of the rail top.

[0030] like Figures 2 to 5 As shown, in embodiment 2, the connecting plate 2 includes an upper plate body 2.1 and a lower plate body 2.2, and the ejector bolt 3 is threadedly installed on the lower plate body 2.2. There are multiple lower plate bodies 2.2 and ejector bolts 3, and the lower plate bodies 2.2 and the ejector bolts 3 are arranged one by one, and the lower plate body 2.2 is slidably installed at the bottom of the upper plate body 2.1 in a direction parallel to the rail. Each lower plate body 2.2 is provided with an ejector bolt 3, and multiple rail bonding bolts can be removed in sequence.

[0031] The bottom of both inner and outer sides of the upper plate 2.1 are provided with a slide groove 8, the top of the lower plate 2.2 is slidably mounted on the bottom of the upper plate 2.1, and a tightening screw 9 is threadedly penetrated on the outer side of the lower plate 2.2. The position of the ejector bolt 3 can be adjusted by sliding the lower plate 2.2 on the upper plate 2.1, and the position of the ejector bolt 3 can be fixed by screwing in the tightening screw 9 so that the tightening screw 9 is pressed against the lower plate 2.2.

[0032] The top of the connecting plate 2 is provided with an upper pin 10 and a lower pin 11 which are distributed up and down, and the outer end of the hook plate 1 is provided with an upper through groove 12 and a lower through groove 13 which are distributed in parallel up and down, and the upper pin 10 and the lower pin 11 are slidably penetrated in the upper through groove 12 and the lower through groove 13 respectively, and the outer end of the hook plate 1 is provided with a control bolt 14 for controlling the inward and outward displacement of the connecting plate 2.

[0033] The upper pin 10 cooperates with the lower pin 11 to slide the connecting plate 2 onto the hook plate 1. By rotating the control bolt 14 to drive the connecting plate 2 to move on the hook plate 1, all the ejection bolts 3 can be controlled to eject the rail bonding bolts at the same time, so as to improve the ejection operation efficiency of the railway bonding bolts.

[0034] The outer end of the lower through groove 13 is connected to an arc-shaped through groove 15 with the outer end of the upper through groove 12 as the center. The top end of the connecting plate 2 is sleeved on the hook plate 1, and the control bolt 14 is rotatably installed on the top end of the outer side surface of the connecting plate 2. A plug block 16 is threadedly sleeved on the control bolt 14, and a slot 17 for inserting the plug block 16 is opened at the top of the hook plate 1.

[0035] In the initial state, the upper pin 10 is located on the outer end of the upper through slot 12. After the hook plate 1 is put on the top of the rail, the connecting plate 2 is rotated downward, and the lower pin 11 moves from the top of the arc-shaped through slot 15 to the lower through slot 13. At this time, the plug block 16 is inserted into the slot 17, and the slot 17 limits the plug block 16 in the circumferential direction of the control bolt 14. Then, the control bolt 14 is rotated to control the displacement of the connecting plate 2 on the hook plate 1, and control all the ejection bolts 3 to eject the rail bonding bolts.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
