A taking and placing hook is welded at one end of the expansion rod. An anti-detachment member is welded on the expansion rod. An anti-detachment plate is inserted into the anti-detachment member. The bottom end of the anti-detachment plate abuts against the outer wall of the taking and placing hook. The anti-detachment plate is connected to the taking and placing hook through a spring. A traction rope is fixed on the anti-detachment plate.
[0006] Further, the rear support rod and the telescopic tube are both tubular. There are two fixing bolts. Both of the two fixing bolts are screwed from the side of the rear support rod and penetrate through the rear support rod and then abut against the inner wall of the expansion rod. Fixing nuts are screwed on both of the two fixing bolts.
[0007] Further, one end of the taking and placing hook is welded on the outer wall of the end of the expansion rod away from the rear support rod, and the other end of the taking and placing hook is bent and horizontally faces the rear support rod.
[0008] Further, the inside of the anti-detachment member is hollow. Chute grooves are provided on both sides of the anti-detachment member. The chute grooves communicate with the inner cavity of the anti-detachment member.
[0009] Further, wing plates are provided on both sides of one end of the anti-detachment plate. A clamping groove is provided at the other end of the anti-detachment plate. The end of the anti-detachment plate with the clamping groove penetrates through the inside of the anti-detachment member and is clamped on the taking and placing hook through the clamping groove. The two wing plates of the anti-detachment plate are respectively inserted into the chute grooves.
[0010] Further, there are two springs. One ends of the two springs are respectively welded on the two wing plates, and the other ends of the two springs are both welded on the outer wall of the expansion rod.
[0011] Furthermore, one end of the towing rope is fixed to the end of the anti-detachment plate provided with the wing plate. After the other end of the towing rope passes through the telescopic rod, the towing rope passes out from the inner cavities of the telescopic rod and the rear support rod.
[0012] The utility model has the following beneficial effects:
[0013] 1. When taking and placing the railway brake shoes, the utility model does not need tools such as ladders, and only needs to stand on the high-altitude platform to complete the work of taking and placing the railway brake shoes. It has a simple structure, convenient operation, good safety and high work efficiency.
[0014] 2. The taking and placing hook can hook the hanging ring of the railway brake shoe, so as to facilitate the taking and placing of the railway brake shoe.
[0015] 3. The anti-detachment plate can close the gap between the telescopic rod and the taking and placing hook, so as to prevent the railway brake shoe from slipping off the taking and placing hook, and improve the safety of the utility model.
[0016] 4. The up and down sliding of the anti-detachment plate is realized through the pulling of the towing rope and the elastic force of the spring, so as to prevent the railway brake shoe from slipping off the taking and placing hook during the taking and placing process. After the taking and placing is completed, the railway brake shoe can be conveniently removed.
[0017] 5. The telescopic function is realized through the rear support rod and the telescopic rod, so as to adapt to the taking and placing of railway brake shoes at different distances. Description of the Drawings

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0022] As Figure 1-2As shown in the figure, a device for picking and placing an iron shoe of a high-altitude crane track includes a rear support rod 1, an expansion rod 2 is inserted into the rear support rod 1, a rubber grip 3 is sleeved at one end of the rear support rod 1, a front handle 4 is welded on the outer wall of the other end of the rear support rod 1, and a number of fixing bolts 5 are screwed thereon. One end of the expansion rod 2 is welded with a picking and placing hook 6, an anti-detachment member 7 is welded on the expansion rod 2, an anti-detachment plate 8 is inserted into the anti-detachment member 7, the bottom end of the anti-detachment plate 8 abuts against the outer wall of the picking and placing hook 6, the anti-detachment plate 8 is connected to the picking and placing hook 6 through a spring 9, and a traction rope 10 is fixed on the anti-detachment plate 8.
[0023] The rear support rod 1 and the telescopic tube are both tubular. There are two fixing bolts 5. Both of the two fixing bolts 5 are screwed from the side of the rear support rod 1 and penetrate through the rear support rod 1 and then abut against the inner wall of the expansion rod 2. Fixing nuts 11 are screwed on both of the two fixing bolts 5. The tubular rear support rod 1 and telescopic tube are convenient for threading the traction rope 10.
[0024] One end of the picking and placing hook 6 is welded on the outer wall of the end of the expansion rod 2 far from the rear support rod 1, and the other end of the picking and placing hook 6 is bent and horizontally faces the rear support rod 1.
[0025] The inside of the anti-detachment member 7 is hollow, and sliding grooves 12 are provided on both sides of the anti-detachment member 7. The sliding grooves 12 communicate with the inner cavity of the anti-detachment member 7. The sliding grooves 12 are used for threading the wing plates 13 of the anti-detachment plate 8.
[0026] Wing plates 13 are provided on both sides of one end of the anti-detachment plate 8, a clamping groove 14 is provided at the other end of the anti-detachment plate 8, the end of the anti-detachment plate 8 provided with the clamping groove 14 penetrates through the inside of the anti-detachment member 7 and is clamped on the picking and placing hook 6 through the clamping groove 14, and the two wing plates 13 of the anti-detachment plate 8 are respectively inserted into the sliding grooves 12. The anti-detachment plate 8 is used to close the gap between the expansion rod 2 and the picking and placing hook 6, so as to prevent the iron shoe from slipping off the picking and placing hook 6.
[0027] There are two springs 9. One ends of the two springs 9 are respectively welded on the two wing plates 13, and the other ends of the two springs 9 are both welded on the outer wall of the expansion rod 2. The spring 9 is used to reset the anti-detachment plate 8 after being pulled.

[0031] When removing the rail brake, loosen the fixing nut 11 and the fixing bolt 5 so that the telescopic rod 2 can slide freely in the rear support rod 1. Adjust the extended length of the telescopic rod 2, and then tighten the fixing nut 11 and the fixing bolt 5. Stand on the high-altitude platform, hold the front lifting handle 4, and pull the towing rope 10. The anti-drop plate 8 is lifted upward under the pulling force, and the spring 9 is compressed. In this way, a gap appears between the anti-drop plate 8 and the pick-up and placement hook 6. Through this gap, the pick-up and placement hook 6 passes through the hanging ring of the rail brake. After releasing the hand, the spring 9 pushes the anti-drop plate 8 back to its original position, and the card slot 14 catches the pick-up and placement hook 6 again. Hold the front lifting handle 4 and the rubber grip 3, pull the rail brake off the track, and pull the towing rope 10 again to remove the rail brake.
