DETAILED DESCRIPTION

[0031] like Figures 1 to 8 As shown, a rail transport mechanism comprises: a rail 1; a transport vehicle 7 arranged on the rail 1 and moving along the rail 1; a transmission mechanism fixed on the rail 1 and used to drive the transport vehicle 7 to move, and the transmission mechanism can be started and stopped at any time; it also comprises a parking mechanism for locking the transport vehicle 7 when the transport vehicle 7 stops, and the parking mechanism comprises a plurality of latch holes 4 distributed on the rail 1 along the extension direction of the rail 1, a locking rod 803 arranged on the transport vehicle 7 and used to selectively insert one of the latch holes 4 to achieve locking of the transport vehicle 7, and the locking rod 803 has a locking state of being inserted into the latch hole 4 and an unlocking state of being out of the latch hole 4.

[0032] like Figure 5 As shown, it also includes a control mechanism for switching the lock rod 803 between the locked state and the unlocked state, and the control mechanism 8 includes:

[0033] The box body 21 is fixed to the side of the transport vehicle 7, and the top wall and bottom wall of the box body 21 are respectively provided with a top opening and a bottom opening for the locking rod 803 to vertically move through;

[0034] The snap ring 807 is movably mounted on the outside of the locking rod 803; the outer side of the snap ring 907 is provided with a first slope;

[0035] The vertical spring 804 is sleeved outside the locking rod 803, and the top end is fixed to the locking rod 803, and the bottom end is fixed to the snap ring 807;

[0036] The block 812 is transversely arranged on one side of the locking rod 803, and a slope block 810 is formed at one end facing the locking rod 803. The slope block 810 includes a horizontal surface at the top and a second slope surface at the bottom. The vertical surface and the side surface of the block 812 together form a groove for blocking the clamping ring 807. The top of the block 812 is provided with a slope groove 811, and the first slope surface and the second slope surface are adapted to each other.

[0037] A transverse spring 813, one end of which is fixed to the side wall of the box body 21 and the other end of which is fixed to the clamping block 812;

[0038] The unlocking rod 808 has a top end fixed on the locking rod 803 at a position above the vertical spring 804, and a bottom end extending downward and facing the block 812. A second slope block 809 adapted to the slope groove 811 is formed at the bottom end of the unlocking rod 808; wherein,

[0039] When the vertical spring 804 and the transverse spring 813 are both in the reset state, the clamping groove is blocked at the bottom of the clamping ring 807, and the second slope block 809 is separated from the slope groove 811, and the locking rod 803 is in the unlocked state;

[0040] When the locking rod 803 is pressed downward to the locked state, the snap ring 807 moves downward lagging behind the locking rod 803 under the action of the vertical spring 804, and the unlocking rod 808 moves downward with the locking rod 803, driving the second slope block 809 and the slope groove 811 to contact each other to push the block 812 laterally, so that the block 812 moves laterally and disengages from the snap ring 807.

[0041] When the locking rod 803 is pulled out to the unlocked state, the first slope of the outer surface of the retaining ring 807 contacts the second slope of the blocking block 812 to push the blocking block 812 laterally, so that the blocking block 812 moves laterally and disengages from the retaining ring 807 .

[0042] like Figure 5 As shown, the vertical spring 804 is divided into at least two sections, and a buffer sleeve 805 is provided between each section of the vertical spring 804. The buffer sleeve 805 can be movably sleeved on the surface of the locking rod 803. In this embodiment, the vertical spring 804 is divided into two sections, and a fixed sleeve 803 is provided on the upper part of the buffer sleeve 805 on the locking rod 803. By dividing the vertical spring 804 into multiple sections and providing the buffer sleeve 805, the retaining ring is prevented from being pulled upward due to the restoring force of the vertical spring 804, thereby preventing the locking rod 802 from escaping from the pin hole 4.

[0043] like Figure 1 to Figure 3As shown, the track 1 comprises: a track frame; a track groove which is opened on the track frame along the extension direction of the track 1, and the transmission mechanism is fixed in the track groove.

[0044] Preferably, if Figure 1 , Figure 2 As shown, a supporting frame 2 is also fixed to the bottom of the track frame.

[0045] like Figure 1 to Figure 3 As shown, the transmission mechanism includes: a plurality of transmission rollers 13 installed in the track groove perpendicular to the extension direction of the track groove, a plurality of transmission rollers 13 are arranged in the track groove along the extension direction of the track groove to form the transmission mechanism, and the transmission rollers 13 are staggered with the pin holes 4.

[0046] like Figure 1 to Figure 4 As shown, the transport vehicle 7 includes: a moving plate 14, which is transmission-connected to the transmission mechanism; and a transport platform, which is fixed above the support member.

[0047] Preferably, if Figure 3 As shown, an anti-slip strip 16 is fixed on the top of the transport platform to prevent the transported objects from sliding out.

[0048] Preferably, if Figure 3 , Figure 4 As shown, it also includes a support member fixed on the top of the movable plate 14 for supporting the transport platform. In this embodiment, the support member is a hydraulic device 15. There are four hydraulic devices 15, which are respectively fixed on the four corners of the movable plate 14. By setting the support member, the transport platform is supported to enhance the stability during cargo transportation.

[0049] In this embodiment, Figure 4 As shown, a fixed connecting ring 18 is sleeved on the outer side of the end of the hydraulic device 15 , and the connecting ring 18 is connected to the moving plate 14 through a nut 19 .

[0050] like Figure 1 to Figure 4 As shown, at least two pairs of wheels 6 are installed at the bottom of the transport vehicle 7. The wheels 6 rotate on the track 1 and are staggered with the transmission mechanism. By arranging the wheels 6, the friction between the transport side 7 and the track can be reduced.

[0051] Preferably, if Figure 3 , Figure 4 As shown, two pairs of support frames 20 are fixed to the bottom of the transport platform, and each pair of support frames 20 is rotatably connected to an axle 17, and both ends of each axle 17 are connected to wheels 6.

[0052] like Figure 1 to Figure 3As shown, it also includes a guide limit groove 5 opened on the track 1 along the extension direction of the track 1 and used to guide the transport vehicle 7. The wheel 6 rotates in the guide limit groove 5. By setting the wire limit groove 5, it can be ensured that the transport vehicle 7 moves in the direction of the track 1 to prevent the transport vehicle 7 from deviating from the track 1.

[0055] like Figure 5 As shown, when the parking mechanism is in use, the locking rod 802 is first pressed downward, and the downward pressure of the locking rod 802 drives the second slope block 809 to be clamped into the slope groove 811. During the contact between the second slope block 809 and the slope surface of the broken groove 811, the clamping block 812 is driven to move sideways, thereby releasing the first slope block 810 from blocking the clamping ring 807 on the locking rod 802, and the locking rod 802 extends downward from the bottom opening of the box body 21 and is inserted into the latch hole 4, and enters the locking position. When the locking state needs to be released, the locking rod 802 is lifted upward, and the slope on the retaining ring 807 contacts the slope on the first slope block 810, so that the block 812 moves to the side again until the slope on the retaining ring 807 contacts the slope on the slope block 810. At this time, the transverse spring 813 is reset, and the block 812 is blocked to the bottom of the retaining ring 807 again, so that the locking rod 802 will not extend from the bottom opening due to gravity, and the unlocked state is maintained.
