Fig. 2 shows a schematic structural view of a rapid solidification device according to an embodiment of the present utility model. As shown, the present utility model provides a quick-fix apparatus 200. The quick-setting device 200 includes a threaded rod 101, a first drive nut 103, a second drive nut 104, and a support sleeve 102. Wherein the threaded rod 101 is threaded on the support sleeve 102. The first speed nut 103 is in threaded engagement with the threaded rod 101. The end face of the first speed nut 103 abuts one side of the support sleeve 102. The rapid solidification device 200 further includes a reinforcement structure, which includes:

a first chuck 201 and a second chuck 202. One side surfaces of the first chuck 201 and the second chuck 202 have concave inner surfaces. Threaded rod 101 is threaded onto first chuck 201 and second opening plate. The concave surfaces of the first chuck 201 and the second chuck 202 are spaced apart opposite. The other side surface of the first chuck 201 is fitted to the other side of the support sleeve 102.

The reinforcing sleeve 203 is hollow. The reinforcing sleeve 203 is formed with projections 204 at both ends. The surface shape of the protrusion 204 is matched with the concave surface. Threaded rod 101 is threaded onto reinforcing sleeve 203. The inner wall of the reinforcing sleeve 203 is fixed in cooperation with the threaded rod 101. The protruding portions 204 at both ends of the reinforcing sleeve 203 are respectively attached to the concave surfaces of the first chuck 201 and the second chuck 202. The second moving nut 104 is screw-engaged with the threaded rod 101, and an end surface of the second moving nut 104 abuts against the other side surface of the second chuck 202.

The first and

second speed nuts

103, 104 axially clamp the support sleeve 102, the first chuck 201, the reinforcement sleeve 203, and the second chuck 202 along the threaded rod 101. The first chuck 201 and the second chuck 202 can be engaged with the reinforcing sleeve 203 by the interaction force between the threaded engagement grooves on the first and

second speed nuts

103, 104 and the threaded rod 101, and the interaction force between the end surfaces of the first and

second speed nuts

103, 104 and the other side surfaces of the support sleeve 102 and the second chuck 202. Since the surface of the protruding portion 204 of the reinforcing sleeve 203 is engaged with the concave surfaces of the first and

second chucks

201 and 202, an interaction force is generated. During the traction process of the test, friction force is generated between the inner wall of the reinforcing sleeve 203 and the threads of the threaded rod 101 so as to achieve the fastening effect, thereby effectively relieving the abrasion of the threads between the first and

second speed nuts

103 and 104 and the threaded rod 101 caused by traction force of the threaded rod 101.

Preferably, the reinforcement sleeve 203 includes an upper sleeve 205 and a lower sleeve 206. It will be readily appreciated that by cutting the reinforcing sleeve 203 along its axis, it is possible to obtain an upper sleeve 205 and a lower sleeve 206, both of which are structurally identical. As shown in fig. 2, the upper sleeve 205 and the lower sleeve 206 can be fitted up and down along the axis of the threaded rod 101. The reinforcing sleeve 203 is designed to facilitate the assembly and disassembly of the reinforcing sleeve 203.

Preferably, the protruding portions 204 at both ends of the reinforcing sleeve 203 have a truncated cone shape, and the cone angle thereof is 35 to 55 °. More preferably, the taper angle is 45 °, which facilitates the mating contact of the reinforcing sleeve 203 and the protrusion 204 to form an interaction force.

Fig. 3 shows a cross-sectional view of the first chuck, the second chuck, and the upper sleeve in one embodiment of the utility model. Fig. 4A is a schematic view of the force applied by the threaded rod of fig. 3 at rest. Fig. 4B is a schematic diagram of the threaded rod of fig. 3 under tension during traction. Referring to fig. 3, the tapered surface angle of the protruding portion 204 of the upper sleeve 205 is 45 °, and the inner concave surfaces of the first chuck 201 and the second chuck 202 are engaged with the surface of the upper sleeve 205. The concave surface of the first chuck 201 generates an interaction force with the tapered surface of one end of the reinforcing sleeve 203. The concave surface of the first chuck 201 applies a force F1 to the tapered surface of one end of the reinforcing sleeve 203. The concave surface of the second chuck 202 generates an interaction force with the tapered surface of the other end of the reinforcing sleeve 203. The concave surface of the second chuck 202 applies a force F2 to the tapered surface of the other end of the reinforcing sleeve 203. The radial component of the forces F1 and F2 towards the threaded rod 101 causes the inner wall of the reinforcement sleeve 203 to engage the threads of the surface of the threaded rod 101. During the traction process, friction force is generated between the two components, so that the two components are more stable in structure, thereby effectively reducing wear between the threaded rod 101 and the first and

second speed nuts

103, 104 due to prolonged traction of the vehicle.

Specifically, because the threaded rod 101 is stressed differently at rest and during traction, the reinforcement sleeve 203 undergoes a corresponding stress change. Referring to fig. 4A and 3, when the threaded rod 101 is stationary, i.e., no traction is generated, the reinforcing sleeve 203 receives its own weight G, and the threaded rod 101 gives it an upward supporting force N. The reinforcement sleeve 203 is subjected to 45 ° downward inclined forces F1 and F2 by the tightening of the first and

second chucks

201, 202. At this time, the acting force f1=f2, the axial component forces of the two cancel each other, and there is no friction between the reinforcing sleeve 203 and the threaded rod 101.

Referring to fig. 4B, when the threaded rod 101 is towing a vehicle, the reinforcing sleeve 203 receives its own weight G, and the threaded rod 101 gives it an upward supporting force N. Reinforcing sleeve 203 is subjected to 45 ° downward-sloping forces F1 and F2, where F1< F2. If the traction is large enough, F1 will drop to 0. Since the axial component of the force F1 is greater than the axial component of the force F2, a friction force F is generated between the reinforcing sleeve 203 and the threaded rod 101. The force balance in the axial direction of the threaded rod 101 satisfies:

F2*COS45°＝F1*COS45°+f

the stress in the gravity direction makes the upper sleeve 205 and the lower sleeve 206 firmly fixed on the threaded rod 101, and the stress balance thereof satisfies:

N＝F1*COS45°+F2*COS45°+G

further, after the reinforcing sleeve 203 is tightly contacted with the first and

second chucks

201 and 202 and is mounted on the threaded rod 101, the reinforcing sleeve 203 is fastened by the clamping force of both sides of the first and

second speed nuts

103 and 104. When traction occurs, friction is generated between the reinforcing sleeve 203 and the threaded rod 101 to slow down the interaction force between the first and

second speed nuts

103, 104 and the threaded rod 101, avoiding thread wear.

Fig. 5 shows a cross-sectional view of the first chuck, the second chuck, and the reinforcing sleeve in one embodiment of the present utility model. Fig. 6 shows a schematic structural view of a first chuck in one embodiment of the present utility model. Fig. 7 shows a schematic structural view of a reinforcing sleeve in one embodiment of the present utility model. As shown, the inner wall of the reinforcement sleeve 203 preferably has internal threads that threadably mate with the threaded rod 101. The position of the reinforcing sleeve 203 on the threaded rod 101 can be conveniently adjusted by rotating the reinforcing sleeve 203.

Preferably, referring to fig. 6, a central hole 207 is provided in the first chuck 201, and an internal thread is provided at the position of the central hole 207 of the first chuck 201. The first chuck 201 is threadedly engaged with the threaded rod 101. Likewise, the center hole 207 of the second chuck 202 is provided with corresponding internal threads. The second chuck 202 is threadedly engaged with the threaded rod 101. Preferably, the first chuck 201 and the second chuck 202 are identical in structure and size, facilitating the production and processing of the first and

second chucks

201, 202. By way of example and not limitation, the first chuck 201 and the second chuck 202 may also be configured differently. For example, the concave surfaces may be different from each other, only requiring a form fit with the two projections 204 of the reinforcement sleeve 203. The differently shaped concave surfaces facilitate providing forces at different angles.

Preferably, referring to FIG. 2, the quick-setting device 200 further includes a retaining pile 208 and height adjustment wheels 209. The support sleeve 102 is disposed within the spud 208. Height adjustment wheels 209 are provided on the anchor piles 208. The height adjustment wheels 209 are used to adjust the relative position of the anchor piles 208 and the support sleeve 102. More preferably, height adjustment wheels 209 are disposed radially of support sleeve 102, and adjustment wheels 209 are used to adjust the radial position of the anchor piles 208 relative to support sleeve 102.
