Description

Technical Field

[0001] The utility model relates to the technical field of port crane rails, in particular to a port crane rail connecting fastener. Background Art

[0002] The crane rail fastener is a fastener used to securely fix the crane rail to the ground (or load-bearing beam). It is arranged along the entire length of the track, with one group set every 500mm, and one group consists of two pairs, symmetrically arranged on both sides of the track. Its main function is to prevent the rail from moving longitudinally and transversely relative to the sleeper and keep it in a stable position.

[0003] Most of the connecting fasteners currently used cannot prevent the thermal expansion and contraction of metals due to long-term use, and are not convenient for fixing the pressure plate.

[0004] After searching, the existing patent [CN 201634961U] discloses a flexible rail pressure plate without water accumulation, which belongs to the field of flexible rail technology. This flexible rail pressure plate without water accumulation relies on the pressure plate base welded on the steel pad to be tightly pressed on the rail with fixing bolts. The pressure plate base is provided with a drainage trough, which is located above the joint between the pressure plate base and the steel pad. This allows the originally closed lower space to have a through hole. On rainy days, rainwater flows from the bolt holes into the bolt slot holes of the pressure plate base, and can be discharged through the drainage trough holes. There is no more water accumulation inside the pressure plate base, thereby preventing the pressure plate base and bolts from rusting and corroding, and extending the service life of the entire track fixing device. This track pressure plate solves the problem that rust may be caused by water accumulation;

[0005] Although the above utility model patent solves the problem that rust may be caused by accumulated water, most of the connecting fasteners currently in use cannot prevent the expansion and contraction of metal due to long-term use. During use, the rail may expand due to long-term exposure to wind and sun, which may cause the pressure plate to not press the rail firmly, reducing the service life of the connecting fastener and making it inconvenient to fix the pressure plate. During use, if the process of fixing the pressure plate is more complicated, it may require professionals to fix and install the pressure plate, which will take a long time to fix the pressure plate, reduce the work efficiency, and be inconvenient to use.

[0006] The utility model aims to provide a port crane rail connecting fastener to solve the problems raised in the prior art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A port crane rail connection fastener comprises a base, characterized in that a clamping mechanism is arranged on the top of the base, and the clamping mechanism comprises a support frame;

[0008] The top of the base is welded with a support frame, and a threaded hole is provided on the top of the support frame. Through the connection between the support frame and the base, the support frame can have a certain support performance.

[0009] As a preferred technical solution, the inner wall of the threaded hole is movably connected with a first threaded rod, and the shape and size of the first threaded rod match the shape and size of the threaded hole.

Through the connection between the second threaded rod and the base, the second threaded rod can have a certain support.

[0013] As a preferred technical solution, a backing plate is movably connected to the outer wall of the second threaded rod, a nut is movably connected to the outer wall of the second threaded rod, and a slot is provided on the top of the pressure plate.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Figure 1 As shown, the utility model provides the following technical solution, including a base 1, a clamping mechanism 2 is arranged on the top of the base 1, a pressure plate 4 is movably connected to the top of the base 1, the number of the pressure plates 4 is two, a track 5 is movably connected to the top of the base 1, and a fixing mechanism 3 is arranged on the top of the base 1.

[0024] Among them: when the connecting fastener is needed, the pressure plate 4 needs to be fixed first, and the pressure plate 4 is fixed by the set fixing mechanism 3, and then the phenomenon of thermal expansion and contraction needs to be prevented by the set clamping mechanism 2 to complete the work.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a clamping mechanism 2 is provided at the top of the base 1, and the clamping mechanism 2 includes a support frame 201. The top of the base 1 is welded to the support frame 201, and a threaded hole 202 is opened on the top of the support frame 201. The inner wall of the threaded hole 202 is movably connected with a first threaded rod 203. There are two first threaded rods 203, and the shape and size of the first threaded rod 203 match the shape and size of the threaded hole 202. A handle 204 is welded to the top end of the first threaded rod 203, and a fixing plate 205 is welded to the bottom end of the first threaded rod 203.

[0026] Among them: when it is necessary to prevent thermal expansion and contraction, the track 5 needs to be further tightened. At this time, hold the handle 204, and then rotate the handle 204. The handle 204 drives the first threaded rod 203 to start rotating. The first threaded rod 203 rotates in the threaded hole 202 on the support frame 201, so that the first threaded rod 203 descends. The first threaded rod 203 drives the fixed plate 205 to start descending, so that the fixed plate 205 further presses the track 5 to prevent thermal expansion and contraction, thereby completing the tightening work.

[0027] like Figure 1 and Figure 4 As shown, a fixing mechanism 3 is provided at the top of the base 1, and the fixing mechanism 3 includes a second threaded rod 301. A second threaded rod 301 is welded at the top of the base 1, and the number of the second threaded rods 301 is two. A pad 302 is movably connected to the outer wall of the second threaded rod 301, and a nut 303 is movably connected to the outer wall of the second threaded rod 301. A slot 304 is opened on the top of the pressure plate 4.

[0028] Among them: when the connecting fastener is needed, the pressure plate 4 needs to be fixed first. At this time, the pressure plate 4 is placed at a suitable position on the base 1, and then the slot 304 on the pressure plate 4 passes through the second threaded rod 301, and then the pressure plate 4 presses the track 5, and then the pad 302 passes through the second threaded rod 301, and then the nut 303 is moved on the outer wall of the second threaded rod 301 by rotation, so that the nut 303 fixes the pad 302 and the pressure plate 4, thereby completing the fixing work.

[0029] The working principle of the utility model is: when the connecting fastener is needed, the pressure plate 4 needs to be fixed first, at this time, the pressure plate 4 is placed in a suitable position of the base 1, and then the slot hole 304 on the pressure plate 4 passes through the second threaded rod 301, and then the pressure plate 4 presses the track 5, and then the pad 302 passes through the second threaded rod 301, and then the nut 303 is moved on the outer wall of the second threaded rod 301 by rotation, so that the nut 303 fixes the pad 302 and the pressure plate 4, thereby completing the fixing work, and then to prevent thermal expansion and contraction, at this time, the track 5 needs to be further tightened, at this time, hold the handle 204, and then rotate the handle 204, the handle 204 drives the first threaded rod 203 to start rotating, the first threaded rod 203 rotates in the threaded hole 202 on the support frame 201, so that the first threaded rod 203 descends, and the first threaded rod 203 drives the fixing plate 205 to start descending, so that the fixing plate 205 further presses the track 5 to prevent thermal expansion and contraction, thereby completing the clamping work.
