Description

Technical Field

[0001] The utility model relates to the technical field of vibrating rod cables, in particular to a connecting structure of a vibrating rod cable for a concrete vibrating trolley. Background Technique

[0002] During the concrete pouring construction of large hydropower stations, special equipment is needed to vibrate the concrete layer, so as to make the concrete evenly mixed and tamped, and fill the internal space of the formwork. In China, the common equipment nowadays is a vibrating rod. Its working principle is to supply 380V voltage to the frequency conversion unit through an external power supply. The frequency conversion unit is the power supply equipment of the electric vibrating rod, which is composed of a motor and a low-voltage asynchronous generator installed on the same shaft. The frequency conversion power supply drives the motor to rotate on the one hand, and on the other hand, accesses the rotor excitation of the generator through the fuse power line carbon brush and slip ring to make the generator output a high-frequency low-voltage power supply for the vibrating rod to use. The centrifugal force generated by the eccentric shaft of the eccentric vibrating rod is transmitted to the housing through the bearing, and finally the vibrating rod body vibrates at a high frequency. In the concrete vibrating rod, the cable as the power line extends into the controller to be connected to the circuit board, etc. The controller housing is provided with an opening for the cable to pass through. The connection between the cable and the controller housing is easy to bend, and the bending amplitude is large. The cable is easy to fatigue and reduce its service life. At the same time, the outer wall of the cable will contact the wall of the opening of the controller housing, and the surface of the cable is easy to be damaged and cracked, which is easy to cause safety accidents.

[0003] In order to solve the above technical problems, the Chinese patent with the publication number CN212182654U in the prior art discloses a connecting structure between a concrete vibrating rod controller and a cable, including a controller housing. The controller housing is provided with a fixed head extending outwards. The fixed head has a through hole. One end of the cable passes through the through hole to extend into the inner cavity, and the other end of the cable is located outside the controller housing. A protective sleeve is sleeved on the part of the cable located outside the controller housing. A concave positioning groove is provided on the outer wall of the fixed head at a position deviating from the end. A convex positioning protrusion is provided on the inner wall of the protective sleeve. The positioning protrusion is fitted in the positioning groove.

[0004] Although the above prior art solution can protect the connection between the cable and the controller housing to improve the service life of the cable, and can improve the waterproof sealing performance and safety, when connecting, it is positioned by a hoop. The hoop is composed of a hoop plate, a wing plate, a tie bar plate, a bolt and a lining pad. When disassembling and assembling, the staff needs to twist the bolts at the installation holes one by one in a circle, which is more cumbersome and time-consuming, affects the installation efficiency, and is not conducive to the staff to quickly separate for maintenance or replacement.

[0022] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment:

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0025] A vibrating rod cable connection structure for a concrete vibrating trolley, including a controller body 1. One end of the controller body 1 is installed with a docking sleeve 2. The inner side of the docking sleeve 2 is slidably connected with a cable body 3. One side of the cable body 3 is lapped with a docking seat 4, and the other side of the cable body 3 is lapped with a fixed seat 16. Rubber pads 17 are embedded on the opposite surfaces of the docking seat 4 and the fixed seat 16. The cable body 3 is snap-connected with the docking sleeve 2 through a protective socket mechanism. The protective socket mechanism includes an elastic pressing component and a torsion component. The elastic pressing component is used to lock the positions of the cable body 3 and the controller body 1, and the torsion component is used to unlock the locking of the position of the cable body 3. When the device is in use, the positions of the cable body 3 and the controller body 1 can be locked through the elastic pressing component, and the locking of the position of the cable body 3 can be unlocked through the torsion component. The structure is simple and the operation is convenient. The staff can quickly separate the cable body 3 for replacement or maintenance. Only by twisting and pressing can it be disassembled and assembled, further improving the work efficiency.

[0026] In this embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the elastic pressing component includes through holes opened at one end inside two groups of rubber pads 17. A clamping block 5 is installed on the outer wall of the docking seat 4 corresponding to the through holes. The outer wall of the clamping block 5 is attached to the inner wall of one of the through holes. A card slot is opened at one side inside the fixed seat 16 corresponding to the through holes. The clamping block 5 is slidably connected with the card slot. First, insert the cable body 3 into the inside of the controller body 1 from the port of the docking sleeve 2 for docking, and then bring the docking seat 4 and the fixed seat 16 closer and fit them, so that the clamping block 5 is pushed into the docking hole and then enters the inside of the card slot.

[0027] In this embodiment, as Figure 3 , Figure 4 and Figure 5 shown, a locking groove is formed on one side of the inner part of the fixing seat 16 inside the card slot. A rotating rod 6 is rotatably connected to the inner side of the locking groove. A spring pressing block 7 is sleeved on the outer side of the rotating rod 6. A connecting groove is formed on one side of the spring pressing block 7. A fixing plate 8 is installed on one side of the inner wall of the locking groove. A connecting spring 9 is installed between the inner wall of the connecting groove and the fixing plate 8. First slopes 10 that fit each other are formed on the fitting surfaces of the clamping block 5 and the spring pressing block 7. Through holes are formed at the other ends of the two groups of rubber pads 17. Plug plates 21 are installed at the corresponding positions of the docking seat 4 and the fixing seat 16 for the through holes. Slots that are slidably connected to the plug plates 21 are formed on both sides of the outer wall of the docking sleeve 2. Then, the two groups of rubber pads 17 that are fitted are squeezed. As the rubber pads 17 retract, the clamping block 5 enters the inner side of the locking groove and contacts the spring pressing block 7, causing the first slopes 10 on the two to be squeezed against each other, forcing the spring pressing block 7 to drive the rotating rod 6 to rotate, and the connecting spring 9 is stretched accordingly. After the clamping block 5 contacts the abutting plate 11, the first slope 10 and the second slope 13 are fitted and squeezed against each other, forcing the abutting rod to drive the return torsion spring 12 to retract, so that the abutting plate 11 completely retracts into the inner side of the retraction groove. Until the abutting groove approaches the retraction groove, the abutting plate 11 is ejected by the return torsion spring 12 into the inner side of the abutting groove. At this time, the docking seat 4 and the fixing seat 16 are released. The two groups of rubber pads 17 rebound and drive the clamping block 5 to move back, and the abutting plate 11 abuts tightly against the inner wall of the abutting groove for fixation. At the same time, the plug plates 21 enter the inner sides of the slots to lock the position of the docking sleeve 2 as well, completing the fitting and docking of the cable main body 3.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a retraction groove is formed inside the spring pressing block 7 at its first slope 10. An abutting rod is rotatably connected to the inner side of the retraction groove. An abutting plate 11 is sleeved on the outer side of the abutting rod. A return torsion spring 12 is installed between the abutting rod and the inner wall of the retraction groove. An abutting groove is formed inside the clamping block 5 at its first slope 10. A second slope 13 that corresponds to and fits the first slope 10 is formed on one side of the abutting plate 11. The torsion assembly includes a limiting groove formed on one side of the inner wall of the locking groove. A limiting plate 14 that is slidably connected to the limiting groove is installed at one end of the spring pressing block 7 away from the first slope 10. An extension groove is formed on one side of the inner part of the fixing seat 16 inside the locking groove. A knob 15 is installed at one end of the rotating rod 6 extending into the inner side of the extension groove. Further, when it is necessary to unlock the connection and locking, twisting the knob 15 can drive the rotating rod 6 to rotate accordingly, actively driving the spring pressing block 7 to rotate. The abutting plate 11 is pulled away from the inner wall of the abutting groove. At this time, the rubber pads 17 are fully reset and rebound. The clamping block 5 continues to move. After the abutting groove and the retraction groove are misaligned, the abutting plate 11 will no longer be stuck into the inner side of the abutting groove. Pulling the fitted cable main body 3 apart can separate it, for maintenance or replacement.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a protective groove is provided on one side of the outer wall of the fixed seat 16 located in the extension groove. A protective plate 18 is slidably connected to the inner side of the protective groove. Synchronization grooves 19 are provided on both sides of the inner wall of the protective groove. Synchronization blocks slidably connected to the synchronization grooves 19 are installed at both ends of the protective plate 18. A magnetic block 20 is embedded and installed at one end of the protective plate 18. An iron block adsorbed by the magnetic block 20 is embedded and installed on the inner wall of the protective groove. Further, when the cable main body 3 is installed, the synchronization groove 19 and the synchronization block can be coordinated to drive the protective plate 18 to move smoothly, so that the magnetic block 20 adsorbs the iron block to cover the knob 15 to prevent accidental touch.

[0030] The implementation principle of the vibrating rod cable connection structure of a concrete vibrating trolley in an embodiment of the present application is as follows: The cable main body 3 is inserted into the inner side of the controller main body 1 from the port of the docking sleeve 2 for docking. Then, the docking seat 4 and the fixed seat 16 are brought close and fitted together, so that the clamping block 5 is pushed into the docking hole and then enters the inner side of the card slot, squeezing the two groups of rubber pads 17 that are fitted together. As the rubber pads 17 retract, the clamping block 5 enters the inner side of the locking groove and contacts the elastic pressing block 7, so that the first slopes 10 on the two are pressed against each other, forcing the elastic pressing block 7 to drive the rotating rod 6 to rotate, and the connecting spring 9 is stretched accordingly. When the clamping block 5 contacts the abutting plate 11, the first slope 10 and the second slope 13 are pressed against each other, forcing the abutting rod to drive the reset torsion spring 12 to retract, so that the abutting plate 11 completely retracts into the retraction groove. Until the abutting groove approaches the retraction groove, the abutting plate 11 is ejected by the reset torsion spring 12 into the inner side of the abutting groove. At this time, the docking seat 4 and the fixed seat 16 are released, and the two groups of rubber pads 17 rebound to drive the clamping block 5 to move back and abut the abutting plate 11 against the inner wall of the abutting groove for fixation. At the same time, the insertion plate 21 enters the inner side of the insertion slot to lock the position of the docking sleeve 2 as well, completing the fitting and docking of the cable main body 3. When it is necessary to unlock the connection, turning the knob 15 can drive the rotating rod 6 to rotate accordingly, actively driving the elastic pressing block 7 to rotate. The abutting plate 11 is pulled away from the inner wall of the abutting groove. At this time, the rubber pads 17 are completely reset and rebound, and the clamping block 5 continues to move. After the abutting groove and the retraction groove are misaligned, the abutting plate 11 will no longer be stuck into the inner side of the abutting groove. Pulling the fitted cable main body 3 apart can separate it for maintenance or replacement. When the cable main body 3 is installed, the synchronization groove 19 and the synchronization block can be coordinated to drive the protective plate 18 to move smoothly, so that the magnetic block 20 adsorbs the iron block to cover the knob 15 to prevent accidental touch.

[0031] The control mode of the present utility model is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be further explained.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
