Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a rammer block continuous lifting transmission component. Background Art

[0002] In large-scale building construction, rammers have always been one of the indispensable operating equipment. Rammers can compact the foundation through regular hammering to ensure that the foundation will not collapse, thereby ensuring the safety of the building.

[0003] According to the control method, rammers can be divided into hydraulic control, pneumatic control and electric control. Hydraulic control can provide a large downward impact, but due to its own structure and connection method, while the rammer provides downward impact, the ground also has a large recoil force on the rammer, and the recoil force will cause damage to the inside of the hydraulic cylinder. Long-term impact may cause serious pressure relief inside the hydraulic cylinder, making the impact force of the rammer insufficient. Pneumatic control can continuously and efficiently increase the downward impact, but the relative impact force is not strong enough. For the foundations of some large buildings, it cannot meet the impact force requirements. Therefore, electric control is more widely used in practical applications.

[0004] In the prior art, the quickest way to ensure that the electrically controlled rammer works continuously is to continuously control the forward and reverse rotation of the motor. However, this method causes great loss to the motor and affects its service life. A common method is to use a transmission mechanism to achieve continuous operation of the rammer. For example, a Chinese invention patent with the announcement number CN116607369A discloses a road leveling frog-type rammer, which drives the pulley assembly to rotate through a motor. The pulley assembly is provided with an eccentric block, and the reciprocating motion of the rammer is achieved through the eccentric block. Although this structure can meet the needs of the rammer operation, its overall power transmission path is long, the power consumption of the required motor is large, and its overall structure is also large. Utility Model Content

[0005] In view of this, the utility model provides a rammer block continuous lifting transmission assembly, aiming to make the power transmission of the rammer simpler and the overall structure more compact.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A rammer block continuous lifting transmission assembly comprises a base and a rammer block which can move up and down relative to the base, and is characterized in that: the rammer block is provided with a rack arranged along its height direction, a rotating component is rotatably installed in the base, and the rotating component is provided with an arc-shaped tooth segment adapted to the rack; within a single-circle rotation stroke of the rotating component, when the arc-shaped tooth segment engages with the rack, the rotation of the rotating component can drive the rammer block to move upward, and when the arc-shaped tooth segment disengages from the rack, the rammer block can fall under its own weight.

[0008] By adopting the above structure, the continuous up and down movement of the rammer block can be achieved by continuously rotating the rotating component, and the overall power transmission path is short and the power transmission efficiency is high.

[0009] Preferably, the rotating part is a gear, and the gear is composed of a meshing section and a non-meshing section in the circumferential direction. With the above structure, the gear is driven to rotate, and the design of the meshing section and the non-meshing section can realize the continuous up and down movement of the rammer block.

[0010] Preferably, the base is a square hole drill bit, and the rammer block can be slidably assembled inside the square hole drill bit. With the above structure, square holes can be punched by rammering.

[0011] Preferably, the rammer block is a rectangular block having a central assembly hole, the rack is fixed on the inner wall of the central assembly hole, a mounting seat located in the central assembly hole is provided inside the square hole drill, and the rotating component is rotatably mounted on the mounting seat. The above structure makes the entire transmission assembly structure more compact.

[0012] Preferably, four sets of racks are arranged on the inner wall of the central assembly hole, and a rotating component is arranged on the mounting seat corresponding to each rack. With the above structure, the rammer block can be subjected to more uniform force during lifting, and has high stability.

[0013] Preferably, a guide rod is provided inside the base body, and the rammer block is inserted inside the guide rod. The above structure can ensure that the rammer block will not deviate when it falls.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The continuous lifting transmission assembly of the rammer block provided by the utility model can realize continuous lifting and lowering of the rammer block by continuously rotating the rotating part through the design of the arc-shaped tooth segment of the rotating part. Power transmission is only performed through the rotating part and the rack, and the rotating part and the rack are both arranged inside the rammer block, which not only shortens the power transmission path and increases the transmission efficiency, but also makes the overall structure more compact.

[0021] The utility model is further described below in conjunction with embodiments and drawings.

[0022] like Figures 1 to 3 As shown, a rammer block continuous lifting transmission assembly includes a base A and a rammer block B that can move up and down relative to the base A. In this embodiment, the base A is a square hole drill bit, and the interior of the square hole drill bit is a hollow structure, and the rammer block B is slidably installed inside the square hole drill bit. A rack 1 is integrally formed or fixed along the height of the rammer block B in a square shape, and a rotating component 2 is rotatably installed inside the base A. The rotating component 2 is provided with an arc-shaped tooth segment 2a adapted to the rack 1. Within a single-circle rotation stroke of the rotating component 2, when the arc-shaped tooth segment 2a is engaged with the rack 1, the rotation of the rotating component 2 can drive the rammer block B to move upward, and when the arc-shaped tooth segment 2a is disengaged from the rack 1, the rammer block B can fall under its own weight.

[0023] With such a design, the rammer block B can be continuously lifted and lowered by continuously rotating the rotating component 2. In addition, the power transmission is only performed through the rotating component 2 and the rack 1, and the overall power transmission structure is simple and the power transmission efficiency is higher.

[0024] In this embodiment, the rotating component 2 is a gear. Figure 3 A meshing section and a non-meshing section 2b are provided in the axial direction of the gear, and the arc-shaped tooth section 2a of the rotating component 2 is the meshing section of the gear.

[0025] In order to ensure the compactness of the entire transmission assembly structure, in this embodiment, the rammer block B has a central assembly hole 4 inside, the rack 1 is integrally formed or fixed to the inner hole wall of the central assembly hole 4, the base A is provided with a mounting seat 5 located in the central assembly hole, and the rotating component 2 is rotatably mounted on the mounting seat 5. In this embodiment, the rammer block B is configured as a rectangular block corresponding to a square hole drill bit, and similarly, the style of the rammer block B can also be changed according to the cross-sectional shape of the drill bit.

[0026] like Figure 4 As shown, the rotating part 2 is fixedly connected to a synchronous wheel 7 through a synchronous rod 6, and the synchronous wheel 7 is used to connect a power source to ensure that the rotating part 2 rotates continuously. In this embodiment, the synchronous wheel 7 is rotatably arranged inside the mounting seat 5, and the power source is a motor 8, and a worm 9 is connected to the output end of the motor 8, and the worm 9 is meshed and assembled with the synchronous wheel 7. Based on this, driving the motor 8 can ensure that the rotating part 2 rotates continuously, thereby ensuring that the rammer block B moves up and down continuously.

[0027] Furthermore, in order to ensure that the rammer block B is subjected to a more uniform force during lifting and the lifting is more stable, in this embodiment, the worm 9 is meshed with two synchronous wheels 7, and two rotating components 2 are fixedly mounted on each synchronous wheel 7, that is, four groups of rotating components 2 and racks 1 are arranged inside the rammer block B. In order to ensure that the rammer block B falls straight when it falls and does not deviate, a guide rod 3 is arranged in the vertical direction inside the base A, and the rammer block B is inserted on the guide rod 3.

[0028] In the actual application of the above transmission structure, it is necessary to ensure that the rotation direction of the motor 8 can enable the rotating component 2 to drive the rammer block B to continuously lift. When the rotation direction of the motor 8 changes due to human error, the rotating component 2 will drive the rammer block B to move downward. When the rammer block B is in the lowest position, the rotating component 2 drives the rammer block B to move downward, which will cause damage to the arc-shaped tooth segment 2a of the rotating component 2 and the rack 1, ultimately affecting the service life of the transmission component. To prevent the above situation from occurring, the output end of the motor 8 is also provided with an anti-reversal mechanism 10 in the application of the transmission component introduced in this embodiment on the square hole drill bit. For details, please refer to Figure 5 .

[0029] The anti-reversal mechanism 10 includes a ratchet tooth 10a fixedly sleeved on the output end of the motor 8 and a locking plate 10b matched with the ratchet tooth 10a. When the motor 8 runs in the normal rotation direction, the output end of the motor 8 drives the ratchet tooth 10a to rotate. Figure 5 At this time, the ratchet teeth 10a rotate counterclockwise and are not affected by the locking plate 10b. The motor 8 can normally drive the rotating component 2 to rotate continuously, thereby driving the rammer block B to continuously lift. When the rotation direction of the motor 8 is opposite to the normal rotation direction due to human error, the rotation of the ratchet teeth 10a is affected by the locking plate 10b and locked. At this time, the motor 8 cannot drive the rotating component 2 to rotate, thereby ensuring the service life of the transmission component.

[0030] When the ratchet teeth 10a and the locking plate 10b are in a locked state, the motor 8 continues to output, but the output end of the motor 8 cannot rotate, which will cause the motor 8 to be overloaded due to heat, affecting the service life of the motor 8. In this embodiment, the locking plate 10b is fixedly mounted on the connecting block 11, the connecting block 11 is fixedly arranged on the base A, and the connecting block 11 is fixedly connected to each guide rod 3. With such a design, when the ratchet teeth 10a and the locking plate 10b are in a locked state, the motor 8 can drive the connecting block 11 to rotate, thereby driving the entire base A and the rammer block B to rotate, thereby avoiding overloading of the motor 8.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
