Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a novel concrete vibrating device. Background Art

[0002] When paving and filling the concrete mixed by a concrete mixer, the bubbles must be removed and the concrete must be compacted to make it dense and combine, and eliminate the honeycomb and other phenomena of the concrete, so as to improve the strength of the concrete and ensure the quality of the concrete components. Therefore, the concrete needs to be vibrated by a concrete vibrator.

[0003] Concrete plate vibrators are widely used due to their wide applicability, high construction quality and efficiency, low maintenance cost, and environmental protection and energy saving. However, existing concrete plate vibrators cannot effectively store power cables. During transfer and transportation, the cables are generally wrapped directly on the frame. The cables are not only easy to get tangled, but the connection with the vibration motor may become loose when the cables are pulled, affecting subsequent use. Therefore, we propose a new concrete vibration device. Utility Model Content

[0004] One of the technical problems to be solved by this application is that the existing concrete plate vibrator cannot effectively store the power supply cables. During the transfer and transportation process, the cables are generally directly wrapped around the frame. The cables are not only easy to get tangled, but the connection with the vibration motor may become loose when the cables are pulled, affecting subsequent use.

[0005] To solve the above technical problems, the present invention provides a novel concrete vibrating device, comprising a frame with a vibration plate fixedly mounted at the bottom end, a vibration motor fixedly connected to the upper surface of the vibration plate, and further comprising:

[0006] a connecting frame, the connecting frame being fixed to the outer side wall of the frame, a rotary joint being installed at one end of the connecting frame, and a connecting cable being electrically connected between the rotary joint and the vibration motor;

[0007] Two rotating discs, the two rotating discs are rotatably connected to the inner walls at both ends of the connecting frame, and a limiting groove is provided on the adjacent side of the two rotating discs. Two hollow winding shafts are provided between the two rotating discs, and the two winding shafts are fixedly connected with a clamping block adapted to the size of the inner cavity of the limiting groove at one end away from each other. A sliding tube is slidably connected between the two winding shafts, and a spring is provided in the sliding tube. The two ends of the spring are respectively fixed to the inner walls of the two winding shafts, and a power transmission cable is wound around the outer surface of the winding shaft, and one end of the power transmission cable is electrically connected to the rotary joint;

[0008] A crank is provided at one end of the connecting frame away from the rotary joint, and the crank passes through the connecting frame and is fixed to the center of the corresponding turntable.

[0009] Preferably, the top end of the frame is bent outward to form a handle, and a rubber sleeve for buffering and shock absorbing is fixed on the outer surface of the handle.

[0010] Preferably, one end of the rotary joint away from the connecting cable passes through the block and extends into the reel, and one end of the power transmission cable close to the rotary joint passes through the side wall of the reel and is electrically connected to the rotary joint.

[0011] Preferably, the length of the connecting cable is greater than the distance between the vibration motor terminal and the rotary joint.

[0012] Preferably, the total length of the two winding shafts is less than the distance between the two turntables.

[0013] Preferably, a main gear is fixedly sleeved on one end of the crank connected to the connecting frame, and a sub-gear connected to the main gear is provided on the outside of the main gear. A reciprocating screw is rotatably connected between the two ends of the connecting frame, and one end of the reciprocating screw is fixed to the center of the sub-gear. A wire ring is sleeved on the middle section of the reciprocating screw, and the bottom end is screwed to the reciprocating screw, and the end of the transmission cable away from the rotary joint passes through the top of the wire ring and is slidably connected to the wire ring.

[0014] Preferably, sliding rods arranged parallel to the reciprocating screw rod are provided on both sides of the bottom end of the wire loop, and the wire loop can slide along the length direction of the sliding rod, and the end of the sliding rod is fixed to the inner side wall of the connecting frame.

[0015] The utility model has at least the following beneficial effects:

[0016] 1. The user can rotate the crank to drive the reel set between the two turntables to rotate, and wind the transmission cable around the reel to achieve the storage of the transmission cable. This avoids the problem that the existing concrete plate vibrator cannot effectively store the transmission cable, and the transmission cable is easy to get tangled during transportation and transfer, affecting subsequent use.

[0017] 2. When the user rotates the crank to reel in the transmission cable, the main gear rotates with the crank to drive the sub-gear to rotate, thereby driving the reciprocating screw rod connected to one end of the sub-gear to rotate, and the bottom end of the wire loop is screwed to the reciprocating screw rod, and the wire loop is limited by the sliding rod and cannot rotate synchronously with the reciprocating screw rod. When the reciprocating screw rod rotates, the thread can be used to push the wire loop back and forth, making it convenient to evenly wind the transmission cable on the reel, which is convenient for the user to use later.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A novel concrete vibrating device includes a frame 1 with a vibration plate 2 fixedly mounted at the bottom end, a vibration motor 3 fixedly connected to the upper surface of the vibration plate 2, and the vibration plate 2 is driven to vibrate at high speed when the vibration motor 3 is energized to compact the laid concrete. The device also includes:

[0029] A connecting frame 5 fixed to the outer wall of the frame 1, with a rotary joint 6 installed at one end of the connecting frame 5, and a connecting cable 7 electrically connecting the rotary joint 6 and the vibration motor 3;

[0030] The two turntables 8 connected to the inner walls of the two ends of the connecting frame 5 are respectively rotatable, and the adjacent sides of the two turntables 8 are provided with limit slots 9. Two hollow winding shafts 10 are provided between the two turntables 8, and the two winding shafts 10 are fixedly connected with a card block 11 adapted to the size of the inner cavity of the limit slot 9 at one end away from each other. A slide tube 12 is slidably connected between the two winding shafts 10, and a spring 13 is provided in the slide tube 12. The two ends of the spring 13 are respectively fixed to the inner walls of the two winding shafts 10, so that the user can slide the two winding shafts 10 toward each other and squeeze the spring 13 to contract, thereby pulling the card block 11 out of the limit slot 9, making it convenient for the user to disassemble the winding shaft 10. A power transmission cable 15 is wound around the outer surface of the winding shaft 10, and one end of the power transmission cable 15 is electrically connected to the rotary joint 6;

[0031] A crank 14 is provided at one end of the connecting frame 5 away from the rotary joint 6. The crank 14 passes through the connecting frame 5 and is fixed to the center of the corresponding turntable 8. When the user rotates the crank 14, the reel 10 between the turntables 8 can be driven to rotate, making it convenient to wind the transmission cable 15 onto the reel 10.

[0032] The top of the frame 1 is bent outward to form a handle 4, and a rubber sleeve for buffering and shock absorbing is fixed on the outer surface of the handle 4;

[0033] The end of the rotary joint 6 away from the connecting cable 7 passes through the block 11 and extends into the reel 10. The end of the power transmission cable 15 close to the rotary joint 6 passes through the side wall of the reel 10 and is electrically connected to the rotary joint 6. The following also includes:

[0034] The length of the connecting cable 7 is greater than the distance between the terminal of the vibration motor 3 and the rotary joint 6. This is to prevent the vibration generated by the vibration motor 3 from pulling the connecting cable 7 when it is working, which may easily cause the ends of the connecting cable 7 to be detached from the rotary joint 6 and the terminal of the vibration motor 3.

[0035] The total length of the two reel shafts 10 is less than the distance between the two turntables 8, which makes it convenient for the user to slide the two reel shafts 10 toward each other along the sliding tube 12, and pull out the block 11 installed at the end of the reel shaft 10 from the limit groove 9 to achieve quick disassembly of the reel shaft 10. When the transmission cable 15 wound on the reel shaft 10 is damaged, it is convenient to quickly replace the transmission cable 15.

[0036] During use, the end of the power transmission cable 15 away from the rotary joint 6 is connected to the power supply, and then the vibration motor 3 is turned on. The vibration motor 3 drives the vibration plate 2 to vibrate at high speed to compact the laid concrete. After use, the user can rotate the crank 14 to drive the winding shaft 10 set between the two turntables 8 to rotate, and the power transmission cable 15 is wound around the winding shaft 10, so as to avoid the problem that the existing concrete plate vibrator cannot effectively store the power transmission cable 15, and the power transmission cable 15 is easily tangled during transportation and transfer, which affects subsequent use.

[0037] When the transmission cable 15 is damaged during use, the user can slide the two reel shafts 10 toward each other, and the extrusion spring 13 will contract, thereby pulling the block 11 set at the end of the reel shaft 10 out of the limit slot 9 opened on the turntable 8. At this time, the user can remove the reel shaft 10 from the turntable 8, making it convenient for the user to repair and replace the transmission cable 15.

[0038] Example 2

[0039] See also Figure 6 , the utility model provides a technical solution:

[0040] Different from Example 1, this solution provides another implementation of the new concrete vibrating device:

[0041] A novel concrete vibrating device includes a frame 1 with a vibration plate 2 fixedly mounted at the bottom end, a vibration motor 3 fixedly connected to the upper surface of the vibration plate 2, and the vibration plate 2 is driven to vibrate at high speed when the vibration motor 3 is energized to compact the laid concrete. The device also includes:

[0042] A connecting frame 5 fixed to the outer wall of the frame 1, with a rotary joint 6 installed at one end of the connecting frame 5, and a connecting cable 7 electrically connecting the rotary joint 6 and the vibration motor 3;

[0043] The two turntables 8 connected to the inner walls of the two ends of the connecting frame 5 are respectively rotatable, and the adjacent sides of the two turntables 8 are provided with limit slots 9. Two hollow winding shafts 10 are provided between the two turntables 8, and the two winding shafts 10 are fixedly connected with a card block 11 adapted to the size of the inner cavity of the limit slot 9 at one end away from each other. A slide tube 12 is slidably connected between the two winding shafts 10, and a spring 13 is provided in the slide tube 12. The two ends of the spring 13 are respectively fixed to the inner walls of the two winding shafts 10, so that the user can slide the two winding shafts 10 toward each other and squeeze the spring 13 to contract, thereby pulling the card block 11 out of the limit slot 9, making it convenient for the user to disassemble the winding shaft 10. A power transmission cable 15 is wound around the outer surface of the winding shaft 10, and one end of the power transmission cable 15 is electrically connected to the rotary joint 6;

[0044] A crank 14 is provided at one end of the connecting frame 5 away from the rotary joint 6. The crank 14 passes through the connecting frame 5 and is fixed to the center of the corresponding turntable 8. When the user rotates the crank 14, the reel 10 between the turntables 8 can be driven to rotate, making it convenient to wind the transmission cable 15 onto the reel 10.

[0045] A main gear 16 is fixedly sleeved on one end of the crank 14 connected to the connecting frame 5, and a sub-gear 17 is provided on the outside of the main gear 16 and is transmission-connected to the main gear 16. A reciprocating screw rod 18 is rotatably connected between the two ends of the connecting frame 5, and one end of the reciprocating screw rod 18 is fixed to the center of the sub-gear 17. A wire ring 19 is sleeved on the middle section of the reciprocating screw rod 18 and is screwed to the bottom end of the reciprocating screw rod 18. The end of the transmission cable 15 away from the rotary joint 6 passes through the top of the wire ring 19 and is slidably connected to the wire ring 19.

[0046] Both sides of the bottom end of the wire ring 19 are penetrated by a slide bar 20 arranged parallel to the reciprocating screw rod 18. The wire ring 19 can slide along the length direction of the slide bar 20, and the end of the slide bar 20 is fixed to the inner wall of the connecting frame 5.

[0047] Since the middle section of the transmission cable 15 passes through the wire loop 19 and is slidably connected to the wire loop 19, when the user rotates the crank 14 to reel in the transmission cable 15, the main gear 16 rotates with the crank 14 to drive the sub-gear 17 to rotate, thereby driving the reciprocating screw rod 18 connected to one end of the sub-gear 17 to rotate, and the bottom end of the wire loop 19 is screwed to the reciprocating screw rod 18, and the wire loop 19 is limited by the sliding rod 20 and cannot rotate synchronously with the reciprocating screw rod 18. When the reciprocating screw rod 18 rotates, the thread can be used to push the wire loop 19 to move back and forth, so that the transmission cable 15 can be evenly wound on the reel 10, which is convenient for the user to use later.
