[0049] In order to make the person skilled in the art better understand the technical scheme of the utility model, the specific embodiments thereof are described in detail below in conjunction with the drawings.

[0050] As shown in Figures 1-6 , a buffer distance adjusting block extractor includes a support 1, a first connecting rod 2, a second connecting rod 3, a vertical connecting rod 4, a draw hook assembly 5, a slide rod 6 and a slide hammer 7.

[0051] In the embodiment, as Figure 1 , 2As shown in Figure 3, the support frame 1 includes a support rod and a base. The support rod is vertically fixed to the base, and reinforcing ribs are provided on both the support rod and the base to enhance the structural stability and bending resistance of the support rod, ensuring the structural strength of the support frame 1. The base has a "U"-shaped, cross-shaped, or "H"-shaped structure, which ensures the support width of the base while reducing its footprint, allowing the base to avoid bolts on the turnout rail pad. From top to bottom, the top of the support rod is hinged to a first connecting rod 2 and a second connecting rod 3, which have the same structural dimensions.

[0052] In an embodiment, such as Figure 1 , 2 As shown in Figure 3, the top of the vertical connecting rod 4 is provided with two hinge holes, which are respectively hinged to the first end of the first connecting rod 2 and the first end of the second connecting rod 3; the bottom of the slide rod 6 is provided with two hinge holes, which are respectively hinged to the second end of the first connecting rod 2 and the second end of the second connecting rod 3. The first connecting rod 2, the second connecting rod 3, the top of the vertical connecting rod 4 and the bottom of the slide rod 6 form a parallelogram mechanism, which is used to ensure that the vertical connecting rod 4 and the slide rod 6 move up and down in parallel, and reduce the resistance when the slide weight 7 falls freely.

[0053] In an embodiment, such as Figure 2 , 4 As shown, the hook assembly 5 includes an adjusting nut 51, an adjusting screw 52, ​​a spring 53, an expansion head 54, and two hooks 55. The top of the adjusting nut 51 is hinged or fixedly connected to the bottom end of the vertical connecting rod 4. The spring 53 is sleeved on the adjusting screw 52, ​​and the top of the spring 53 is threadedly connected to the bottom end of the adjusting nut 51. The expansion head 54 is slidably sleeved on the adjusting screw 52, ​​and the bottom end of the spring 53 is connected to the top end of the expansion head 54. The tops of the two hooks 55 are movable and limited within the expansion head 54. A chamfer is provided between the hexagonal head at the bottom of the adjusting screw 52 and the rod body, so that the bottom of the adjusting screw 52 forms a conical surface, which facilitates the opening of the two hooks 55 along the conical surface at the bottom of the adjusting screw 52 and prevents the two hooks 55 from being obstructed during the opening process.

[0054] When the operator pulls the expansion head 54 upward, the spring 53 is compressed, and the two hooks 55 are disengaged from the limit of the head of the adjusting screw 52, ​​so that the two hooks 55 can close and stick to the body of the adjusting screw 52, ​​and then the two hooks 55 can be inserted into the hole of the buffer adjustment block 8.

[0055] In an embodiment, such as Figure 2 As shown, the threaded tube 71 at the top of the slide hammer 7 is used to install the counterweight ring 72, and the internal thread of the counterweight ring 72 mates with the external thread of the threaded tube 71. The counterweight ring 72 is used to increase the weight of the slide hammer 7, thereby increasing the impact force of the slide hammer 7 on the striking block 61 and improving the extraction efficiency of the buffer adjustment block 8.

[0056] like Figure 2As shown, the limiting screw 62 at the top of the slide rod 6 is used to install the limiting nut 63, which is used to prevent the slide hammer 7 from falling off the top of the slide rod 6 when the worker operates the slide hammer 7. The diameter of the limiting screw 62 is smaller than the diameter of the slide rod 6, which facilitates the installation and removal of the slide hammer 7 and the counterweight ring 72 on the slide rod 6.

[0057] In the embodiment, as shown in the drawings, Figure 2 As shown, the knocking block 61 is a spherical structure, and the bottom end of the slide hammer 7 is provided with a concave surface matched with the spherical surface of the knocking block 61. The surface of the slide rod 6 is relatively smooth, which is used to reduce the resistance when the slide hammer 7 slides on the slide rod 6.

[0058] In the embodiment, the hinge shafts of the first connecting rod 2, the second connecting rod 3, the bracket 1, the vertical connecting rod 4 and the slide rod 6 are pins or bolts, and the surfaces of the bracket 1, the first connecting rod 2, the second connecting rod 3, the vertical connecting rod 4 and the slide rod 6 are coated with anticorrosive paint or plated with rust-proof plating layer.

[0059] The working mode of the utility model is as follows:

[0060] Step 1: The worker places the base 11 of the bracket 1 of the device on the rail pad beside the buffer distance adjusting block 8 to be taken out, and rotates the drag hook assembly 5 to the position directly above the buffer distance adjusting block 8.

[0061] Step 2: The worker pulls the expansion head 54 upward to compress the spring 53, so that the two clamping hooks 55 are separated from the limiting position of the head of the adjusting screw 52, and the two clamping hooks 55 can be folded to be close to the shaft of the adjusting screw 52.

[0062] Step 3: The worker holds the two clamping hooks 55 to be close to the shaft of the adjusting screw 52, and then inserts them into the hole of the buffer distance adjusting block 8, and then releases the two clamping hooks 55 to hook the two sides of the bottom of the buffer distance adjusting block 8.

[0063] Step 4: The worker holds the slide hammer 7 and slides it upward to the top of the slide rod 6, and then releases the slide hammer 7. The slide hammer 7 freely falls along the slide rod 6 and knocks the knocking block 61 at the bottom of the slide rod 6. The slide hammer 7 and the slide rod 6 impact the second ends of the first connecting rod 2 and the second connecting rod 3, so that the second ends of the first connecting rod 2 and the second connecting rod 3 are pressed downward, the first ends of the first connecting rod 2 and the second connecting rod 3 are raised upward at the same time, and the buffer distance adjusting block 8 is pulled upward through the vertical connecting rod 4 and the drag hook assembly 5.

[0064] Step 5: Repeat the operation of Step 4 above until the buffer distance adjusting block 8 is pulled out. If the buffer distance adjusting block 8 is installed too tightly, the worker holds the slide hammer 7 and slides it downward to knock the knocking block 61 at the bottom of the slide rod 6 after sliding the slide hammer 7 upward to the top of the slide rod 6, so as to increase the impact force of the slide hammer 7.

[0065] When folding the device, the slide rod 6 is connected with the first connecting rod 2 and the second connecting rod 3 by removing the pin or bolt, then the direction of the slide rod 6 is turned, the two hinged holes at the bottom of the slide rod 6 are turned to the top of the slide rod 6, then the two hinged holes at the top of the slide rod 6 are connected with the hinged holes at the second end of the first connecting rod 2 and the second connecting rod 3.
