DETAILED DESCRIPTION

[0037] In order to make the technical personnel in the field better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with the drawings.

[0038] The present application provides a monorail drive wheel as shown in Figures 1-8 The wheel hub 1 is bonded with polyurethane encapsulation 2 on the outer ring, and the drive slot 3 is provided in the center position of the inner ring of the wheel hub 1, and the drive shaft 4 is movably installed in the drive slot 3, and the cavity 7 is provided in the inside of the wheel hub 1, further comprising:

[0039] The stabilizing mechanism 8 is fixed with the fixed base 85 in the cavity 7, and the telescopic rod one 84 is fixed above the fixed base 85, and the telescopic rod one 84 is connected with the limiting block 82 fixed below one of the clamping blocks 81;

[0040] The synchronous mechanism 9 is provided with the channel one 92 and the channel two 94 in the clamping block 81, and the long rod one 91 and the long rod two 93 are movably installed in the channel one 92 and the channel two 94 respectively, and the support rod 95 is fixed at the bottom of the long rod one 91 and the long rod two 93, and the support rod 95 is movably arranged in the channel three 96 at the bottom;

[0041] The secondary limiting mechanism 11 is provided with the cylindrical slot 111 in the clamping block 81, and the telescopic rod two 112 is fixed in the cylindrical slot 111, and the top block 113 is fixed at the top of the telescopic rod two 112, and the top block 113 is matched with the limiting slot 114.

[0042] The outer ring of the drive shaft body 4 is fixedly connected with a positioning block 5, the length of the positioning block 5 is equal to the thickness of the hub 1, and the positioning block 5 is matched with a preset positioning notch 6 in the hub 1, and the positioning notch 6 is communicated with the driving groove 3;

[0043] The outer ring of the drive shaft body 4 is in close contact with the inner wall of the driving groove 3 and is slidably connected, which facilitates the subsequent simple installation of the drive shaft body 4 and the driving groove 3.

[0044] The cavity 7 is a ring-shaped cavity with a certain thickness.

[0045] The four clamping blocks 81 are arranged in a ring array at intervals of 90 degrees, and the four clamping blocks 81 form a cross shape.

[0046] The lower end of the inverted "T"-shaped limiting block 82 is in close contact with and slidably connected with the inner wall of the limiting groove 83 in the cavity 7, which ensures the stability of the movement of the clamping block 81.

[0047] The end of the four clamping blocks 81 away from the limiting block 82 penetrates the hub 1 and extends into the driving groove 3, and the four clamping blocks 81 are matched with four groups of clamping grooves 10 in the drive shaft body 4, and the matching of the four groups of clamping blocks 81 and the clamping grooves 10 ensures the tightness of the installation of the drive shaft body 4 and the driving groove 3.

[0048] One of the limiting blocks 82 is externally fixed with a telescopic rod one 84, which drives one of the clamping blocks 81 to move, and then synchronously drives multiple groups of clamping blocks 81 to move synchronously through the long rod one 91 and the long rod two 93.

[0049] The two long rods one 91 are located above the two long rods two 93, and the inclined directions of the two long rods one 91 and the two long rods two 93 are opposite.

[0050] The two long rods one 91 are respectively in close contact with and slidably connected with the inner walls of four groups of inclined grooves one 92 in the four clamping blocks 81 in the north-west and south-east directions, and the two long rods two 93 are respectively in close contact with and slidably connected with the inner walls of four groups of inclined grooves two 94 in the four clamping blocks 81 in the south-west and north-east directions. Figure 3 For example);

[0051] The bottom of the long rod one 91 and the bottom of the long rod two 93 are fixed with a support rod 95, and the bottom of the support rod 95 is in close contact with and slidably connected with the inner wall of the inclined groove three 96 in the cavity 7.

[0052] The two ends of the channel one 92 and the channel two 94 are through, which facilitates the movement of the one clamping block 81 to drive the movement of the long rod one 91 and the long rod two 93, and then synchronously drive the movement of the other clamping blocks 81 connected with the long rod one 91 and the long rod two 93, so as to promote the synchronous movement of the four groups of clamping blocks 81.

[0053] The clamping block 81 in the west direction is internally provided with a cylindrical groove 111, and the movable end of the telescopic rod two 112 fixedly connected in the cylindrical groove 111 is fixedly connected with the top block 113 matched with the pre-set limiting groove 114 in the clamping block 81 in the east direction.

[0054] The distance between the two side walls of the top block 113 is less than the diameter of the column body of the movable end of the telescopic rod two 112, and the telescopic rod two 112 crosses the pre-set through hole in the driving shaft body 4, and the telescopic rod two 112 drives the top block 113 to pass through the pre-set hole in the driving shaft body 4 and match with the limiting groove 114, so that the telescopic rod two 112 crosses the inside of the driving shaft body 4, so that the position of the driving shaft body 4 is limited twice, and the tightness of the installation of the driving shaft body 4 and the driving groove hole 3 is ensured.

[0055] Working principle: when using a single rail drive wheel, first, when the driving shaft body 4 needs to be installed, first start the telescopic rod two 112, ensure that the telescopic rod two 112 is in a fully retracted state, at this time the top block 113 fixedly connected at the movable end of the telescopic rod two 112 is fully retracted into the cylindrical groove 111 in the clamping block 81 in the west direction;

[0056] Start the telescopic rod one 84, and the telescopic rod one 84 is stretched to drive the movement of the limiting block 82 fixedly connected with the telescopic rod one 84 and the clamping block 81 fixedly connected with the limiting block 82, so as to Figure 8 For example, assuming that the clamping block 81 moves towards the inside of the cavity 7 along the direction indicated by the left arrow, since the long rod one 91 is movably connected in the channel one 92 in the inside of each clamping block 81, and the long rod two 93 is movably connected in the channel two 94 in the inside of each clamping block 81, when one of the clamping blocks 81 moves towards the inside of the cavity 7 along with the stretching of the telescopic rod one 84, the inclined long rod one 91 and the long rod two 93 in the inside of the clamping block 81 move along the Figure 8 The left upper and right lower arrows, respectively, the long rod one 91 and the long rod two 93 are fixedly connected with the support rod 95 at the bottom, the support rod 95 is movably connected in the inclined channel three 96, which ensures the stability of the movement of the long rod one 91 and the long rod two 93, and at the same time, the other two clamping blocks 81 movably connected with the long rod one 91 and the long rod two 93 are synchronously driven to move along Figure 8The two blocks move in the directions indicated by the upward and downward arrows. Because long rod 1 91 and long rod 2 93 are inclined relative to the locking block 81, the internal channels 1 92 and 2 94 of the locking block 81 are also inclined relative to the locking block 81. When long rod 1 91 and long rod 2 93 move, the inclined surfaces of long rod 1 91 and long rod 2 93 abut against the two locking blocks 81, thus pushing the two locking blocks 81 to move in the directions indicated by the upward and downward arrows (at the same time, the limiting block 82 fixed at the bottom of the locking block 81 limits the direction and position of the movement of the locking block 81, so that the locking block 81 moves in a straight line). At this time, during the movement, the two locking blocks 81 move along the other two long rods 1 91 and long rod 2 93 that are movably connected inside the two locking blocks 81. Figure 8 Move in the direction indicated by the upper right and lower right arrows, thereby moving the last locking block 81 along the right-pointing arrow. This causes the four locking blocks 81 to move synchronously in four directions. The four locking blocks 81 are completely retracted into the cavity 7. At this time, align the drive shaft 4 and the positioning block 5 fixed outside the drive shaft 4 with the drive slot 3 and the positioning slot 6. When the end of the positioning block 5 is flush with the surface of the hub 1, stop the movement of the drive shaft 4. Then start the telescopic rod 84. At this time, the telescopic rod 84 retracts inward, driving the four sets of locking blocks 81 to perform a reset movement, so that the four sets of locking blocks 81 are completely engaged in the locking groove 10 inside the drive shaft 4. This is how the drive shaft 4 and the drive slot 3 are installed.

[0057] Meanwhile, after the drive shaft 4 and drive slot 3 are installed, the telescopic rod 112 is activated to drive the top block 113 fixed at the front end of the telescopic rod 112 to engage inside the limiting slot 114. Since the telescopic rod 112 passes through the inside of the drive shaft 4, the position of the drive shaft 4 is limited a second time, ensuring the tightness of the installation between the drive shaft 4 and the drive slot 3.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
