[0019] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] like Figures 1 to 6As shown, a bolt machine rail holding mechanism includes a frame 1, a screw rod 2, a lifting plate 3 and a lifting motor 4. A bottom plate 5 is horizontally installed on the frame 1, a pair of columns 6 are parallelly installed on the bottom plate 5, a top plate 7 parallel to the bottom plate 5 is fixed on the top of the column 6, the top of the screw rod 2 is rotatably connected to the top plate 7, and the bottom is rotatably connected to the bottom plate 5. The lifting motor 4 is installed on the top plate 7, and the output end of the lifting motor 4 is connected to the screw rod 2 through a transmission mechanism. The lifting plate 3 is arranged between a pair of columns 6, and grooves matching the columns 6 are opened on both sides of the lifting plate 3. A nut 8 is installed on the lifting plate 3, and the nut 8 is threadedly matched with the screw rod 2. Two downward pressure rods 9 are installed on the lifting plate 3, and the two downward pressure rods 9 are symmetrical with respect to the screw rod 2. This design is conducive to the force balance of the connecting rod 11 during operation. Two guide rods 10 are provided on the bottom plate 5 corresponding to the lower pressure rod 9, and the bottom end of the guide rod 10 is connected to a connecting rod 11, and the end of the connecting rod 11 is rotatably connected to one end of a support rod 12, and the other end of the support rod 12 is rotatably connected to the top of a wheel shaft 13, and the bottom end of the wheel shaft 13 is rotatably installed with a rotating wheel 14, and the middle part of the wheel shaft 13 is rotatably connected to a rotating shaft 15, and the rotating shaft 15 is fixed on the frame 1. Both ends of the connecting rod 11 are symmetrically rotatably connected to two support rods 12, and the other end of each support rod 12 is rotatably connected to a wheel shaft 13.

[0021] The transmission mechanism includes a driving wheel 16 , a driven wheel 17 and a belt 18 . The driving wheel 16 is installed at the output end of the lifting motor 4 , and the driven wheel 17 is installed at the top of the screw rod 2 . The driving wheel 16 and the driven wheel 17 are connected by the belt 18 .

[0022] In this embodiment, a mounting hole is opened on the lifting plate 3, a limit head 19 is set at the top of the lower pressure rod 9, and the bottom end passes through the mounting hole. A protective spring 20 is sleeved on the lower pressure rod 9, and a spring sleeve 21 is threadedly connected to the lower pressure rod 9. The top of the spring sleeve 21 is open, and the protective spring 20 is placed in the spring sleeve 21.

[0023] In this embodiment, the guide rod 10 is movably mounted on the base plate 5 , the top end of the guide rod 10 is threadedly connected to the guide head 23 , a return spring 24 is sleeved on the guide rod 10 , and the return spring 24 is located between the base plate 5 and the guide head 23 .

[0024] In this embodiment, the bottom end of the lower pressing rod 9 is threadedly connected to the pressing head 22 , the bottom end of the pressing head 22 has a conical surface, and the top end of the guide head 23 is provided with a hole matching the bottom end of the pressing head 22 .

[0025] In this embodiment, a limit bolt 25 is threadedly connected to the connecting rod 11, and the limit bolt 25 is vertically arranged to pass through the connecting rod 11 from bottom to top. By rotating the limit bolt 25, the gap between the bottom end of the limit bolt 25 and the bottom surface of the base plate 5 can be adjusted, thereby adjusting the maximum opening degree of the wheel 14, ensuring that there is a certain amount of activity between the wheel 14 and the rail, and ensuring that the bolt machine can move on the rail.

[0026] In this embodiment, a guide column 26 is provided between the top plate 7 and the bottom plate 5 , and a guide sleeve 27 is slidably fitted on the guide column 26 , and the guide sleeve 27 is detachably connected to the lifting plate 3 .

[0027] In the initial state, the return spring 24 is in a natural state. The return spring 24 supports the guide rod 10 through the guide head 23, so that the connecting rod 11 moves up, and the connecting rod 11 drives the support rod 12 at the end to move up, thereby driving the top end of the axle 13 to move inward, and the rotating wheel 14 at the bottom end of the axle 13 moves outward, so that the rotating wheel 14 is just in contact with the rail. When the bolt machine moves on the rail, the rotating wheel 14 plays a guiding role.

[0028] During operation, the lifting motor 4 works, driving the screw rod 2 to rotate, and then driving the lifting plate 3 to move downward, and the pressure head 22 at the bottom of the lower pressure rod 9 contacts the guide head 23 at the top of the guide rod 10. At this time, the protection spring 20 and the reset spring 24 are both in a natural state. As the pressure head 22 continues to move downward, the reset spring 24 is compressed, and the guide rod 10 drives the connecting rod 11 to move downward, thereby driving the inner end of the support rod 12 to move downward, and the outer end of the support rod 12 drives the top of the wheel shaft 13 to move outward, so that the rotating wheel 14 at the bottom of the wheel shaft 13 moves inward, so that the rotating wheel 14 gradually holds the rail tightly, and the rotating wheel 14 plays a role of limiting. As the degree of the rotating wheel 14 holding the rail tightly increases, the protection spring 20 is compressed. This structural design is conducive to the protection mechanism.

[0029] After the work is completed, the lifting motor 4 drives the screw 2 to rotate, and then drives the lifting plate 3 to reset, the protection spring 20 drives the lower pressure rod 9 to reset, the reset spring 24 drives the guide rod 10 to reset, and the rotating wheel 14 releases the rail. At this time, the rotating wheel plays a guiding role again.

[0030] The utility model organically integrates the rail holding mechanism and the guiding mechanism, realizes the functions of holding the rail during work and guiding during travel, and is beneficial to reducing the number of mechanisms.
