Description

Technical Field

[0001] This utility model relates to the field of compaction technology, specifically to a compaction device with adjustable weight. Background Technology

[0002] Compaction is a fundamental and crucial task, commonly used in construction, road building, and other engineering fields. Its purpose is to compact foundation materials such as soil and gravel, thereby improving the load-bearing capacity and stability of the foundation. In the industrial sector, compaction is also employed to compact industrial raw materials. Traditional compaction equipment often has limitations, such as fixed weight, making it impossible to flexibly adjust to different compaction needs. When faced with different materials to be compacted, required compaction depth, and working environments, fixed-weight compaction equipment may not achieve optimal compaction results.

[0003] Existing adjustable-weight compaction devices often have complex adjustment methods and are inconvenient to operate. For example, Chinese Patent Application No. 201910504258.8 discloses an adjustable-weight compaction device. This patent effectively solves the problems of limited applicability and cumbersome operation of non-adjustable compaction weight compaction devices. The technical solution includes: spaced-apart mounting plates on a trolley, with three sets of counterweight rods that cooperate with each other and are in a fixed state between the mounting plates. A compaction device is vertically slidably connected to the mounting plates. When the motor drives the compaction device to lift to different heights, it can unlock and fix the counterweight rods at different heights, and compact the ground together with the compaction device, thereby achieving the effect of changing the compaction weight. The entire operation process is highly automated, greatly improving construction efficiency and reducing the burden on workers.

[0004] Although the aforementioned patent effectively solves the problems of the compaction device's non-adjustable compaction weight, narrow applicability, and cumbersome and complex operation, in actual use, the patent's internal structure is too complex. This requires maintenance of a large number of components during later maintenance, necessitating targeted maintenance by professionals. This not only delays the work process to some extent but also increases production costs. Furthermore, it makes it difficult to identify potential safety hazards during use, thus reducing the practicality of the patent to some extent.

[0005] Therefore, a weight-adjustable compaction device is needed to solve the aforementioned problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a compaction device with adjustable weight.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a weight-adjustable compaction device, comprising a base, with movable wheels fixedly connected to the four corners of the base bottom, a protective shell fixedly connected to the top of the base, a drop opening at the center of the base, and fixed plates symmetrically fixedly connected to the top of the base about the drop opening, the fixed plates being fixedly connected to the protective shell, a lifting opening on the inner side of the fixed plates, a lifting frame slidably connected inside the lifting opening, and a placement opening on the front of the protective shell, the placement opening being located between the two fixed plates. The bottom of the lifting frame is fixedly connected to a tamping block, and the top of the lifting port is fixedly connected to a support frame. A winding roller is rotatably connected inside the support frame. A reduction motor is fixedly connected to one side of the winding roller through the support frame, and the reduction motor is fixedly connected to a fixed plate. A steel wire rope is wound on the surface of the winding roller, and the steel wire rope is fixedly connected to the lifting frame through a lifting lug. The surface of the protective shell has symmetrical storage slots about the placement port. Several counterweight plates are slidably connected inside one side of the storage slot, and the counterweight plates are vertically and evenly arranged and used in conjunction with the lifting frame.

[0008] As a preferred embodiment of this utility model, the protective shell has symmetrical grooves on both sides of its front side, weight-increasing blocks are provided inside the grooves, and reinforcing blocks are symmetrically provided on the surface of the weight-increasing blocks, and the reinforcing blocks are fixedly connected to the base by bolts.

[0009] As a preferred embodiment of this utility model, the inner side of the fixing plate is symmetrically provided with limit grooves about the lifting port, and the surface of the lifting frame is symmetrically fixedly connected with limit blocks, and the limit blocks are slidably connected with the limit grooves.

[0010] As a preferred embodiment of this utility model, the inner wall of the lifting frame is symmetrically provided with clamping grooves, and a lead screw is rotatably connected inside the clamping groove. The top of the lead screw passes through the lifting frame and is fixedly connected to a torsion block. The surface of the lead screw is threadedly connected to a clamping frame, and the clamping frame is used in conjunction with a counterweight plate.

[0011] As a preferred embodiment of this utility model, the lifting frame has a single door hinged to its front, and the lifting frame has symmetrically provided locking grooves on its front. The bottom of the single door is symmetrically fixedly connected with locking blocks, and the locking grooves and locking blocks are used in conjunction.

[0012] As a preferred embodiment of this utility model, the groove wall of the snap-fit ​​groove is symmetrically provided with locking grooves, the surface of the snap-fit ​​block is provided with locking holes, the interior of the locking holes is symmetrically slidably connected with locking pins, and the locking pins are snapped into the locking grooves, and a fastening spring is fixedly connected between the two locking pins.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the cooperation of a base, protective shell, fixing plate, lifting port, lifting frame, placement port, compaction block, support frame, winding roller, reduction motor and wire rope, can move the lifting frame upward. Then, through the principle of free fall, when the lifting frame and compaction block fall, their gravitational potential energy will be converted into kinetic energy, thereby compacting the material. If it is necessary to increase the weight of the compaction block, simply place the counterweight plate in the storage slot into the lifting frame to increase the weight of the compaction block. The operation is convenient and easy to maintain later.

[0015] 2. By adding weight blocks and reinforcing blocks, this utility model can increase the weight of the device during use, thereby improving its stability. When the compaction block applies an impact force to the compacted material, the compacted material will generate a reaction force of equal magnitude and opposite direction. If the compaction device itself is too light, it is easy to cause unstable phenomena such as jumping and displacement under the action of the reaction force, affecting the accuracy and continuity of compaction. At the same time, sufficient weight helps to disperse the impact of the reaction force on the structure of the compaction device itself and reduce the stress on the various components of the compaction device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a weight-adjustable compaction device, including a base 1. Four casters are fixedly connected to the four corners of the base 1. A protective shell 2 is fixedly connected to the top of the base 1. A drop opening is provided at the center of the base 1. Push handles are symmetrically fixedly connected to the surface of the protective shell 2. Fixed plates 3 are symmetrically fixedly connected to the top of the base 1 about the drop opening, and the fixed plates 3 are fixedly connected to the protective shell 2. A lifting opening 4 is provided on the inner side of the fixed plates 3. A lifting frame 5 is slidably connected inside the lifting opening 4. A placement opening 6 is provided on the front of the protective shell 2, and the placement opening 6 is located between the two fixed plates 3. A compaction block 7 is fixedly connected to the bottom of the lifting frame 5. The top of the lifting opening 4... A support frame 8 is fixedly connected, and a winding roller 9 is rotatably connected inside the support frame 8. One side of the winding roller 9 passes through the support frame 8 and is fixedly connected to a reduction motor 10, which is also fixedly connected to a fixed plate 3. A steel wire rope 11 is wound on the surface of the winding roller 9, and the steel wire rope 11 is fixedly connected to the lifting frame 5 through a lifting lug. The surface of the protective shell 2 is symmetrically provided with storage slots 12 about the placement opening 6. A storage door is hinged inside the storage slot 12. Several counterweight plates 13 are slidably connected inside one side of the storage slot 12, and the counterweight plates 13 are arranged vertically and evenly and used in conjunction with the lifting frame 5. A control unit is fixedly connected inside the other side of the storage slot 12.

[0023] refer to Figure 1 and Figure 2 The protective shell 2 has symmetrical grooves on both sides of the front. The grooves are equipped with weight-increasing blocks 14. The surface of the weight-increasing blocks 14 is symmetrically equipped with reinforcing blocks 15, and the reinforcing blocks 15 are fixedly connected to the base 1 by bolts.

[0024] As a technical optimization of this utility model, by setting up the weight-adding block 14 and the reinforcing block 15, the weight of the device during use can be increased, thereby improving its stability. When the compaction block 7 applies an impact force to the compacted material, the compacted material will generate a reaction force of equal magnitude and opposite direction. If the compaction device itself is too light, it is easy to produce unstable phenomena such as jumping and displacement under the action of the reaction force, affecting the accuracy and continuity of compaction. At the same time, sufficient weight helps to disperse the impact of the reaction force on the structure of the compaction device itself and reduce the stress borne by each component of the compaction device.

[0025] refer to Figure 2 The inner side of the fixed plate 3 is symmetrically provided with limit grooves 16 about the lifting port 4. The surface of the lifting frame 5 is symmetrically fixedly connected with limit blocks 17, and the limit blocks 17 are slidably connected with the limit grooves 16. The surface of the limit blocks 17 is rotatably connected with balls, and the balls are rotatably connected with the limit grooves 16.

[0026] As a technical optimization of this utility model, the position of the lifting frame 5 can be restricted by the setting of the limiting groove 16, the limiting block 17 and the ball, so that it can only perform linear up and down movement.

[0027] refer to Figure 3 The inner wall of the lifting frame 5 is symmetrically provided with clamping grooves. The inside of the clamping groove is rotatably connected to a lead screw 18. The top of the lead screw 18 passes through the lifting frame 5 and is fixedly connected to a torsion block 19. The surface of the lead screw 18 is threadedly connected to a clamping frame 20, and the clamping frame 20 is used in conjunction with the counterweight plate 13.

[0028] As a technical optimization of this utility model, the counterweight plate 13 can be clamped by setting up the clamping groove, the lead screw 18, the torsion block 19 and the clamping frame 20, thereby avoiding unstable phenomena such as jumping and displacement caused by the reaction force during the compaction process.

[0029] refer to Figure 2 and Figure 4 The lifting frame 5 has a single door 21 hinged to the front. The lifting frame 5 has symmetrically opened locking grooves on the front. The bottom of the single door 21 is symmetrically fixedly connected to a locking block 22, and the locking groove and the locking block 22 are used in conjunction.

[0030] As a technical optimization of this utility model, the setting of single door 21, locking groove and locking block 22 makes it easier for staff to load counterweight plate 13 into lifting frame 5, thus improving the convenience of use.

[0031] refer to Figure 4 The groove wall of the snap-fit ​​groove is symmetrically provided with locking grooves 23, and the surface of the snap-fit ​​block 22 is provided with locking holes. The locking holes are symmetrically slidably connected with locking pins 24, and the locking pins 24 are snapped into the locking grooves 23. A fastening spring 25 is fixedly connected between the two locking pins 24.

[0032] As a technical optimization of this utility model, the locking groove 23, locking hole, locking post 24 and fastening spring 25 can lock the position of the snap-fit ​​block 22 and prevent the snap-fit ​​block 22 from becoming loose during use.

[0033] The working principle and usage process of this utility model are as follows: When using this compaction device to compact materials, firstly, move the compaction device to the designated position using the pusher and moving wheels. Then, press the locking pin 24 to disengage it from the locking groove 23 and retract it into the locking hole, and tighten the spring 25 to compress it. Then, flip the single door 21 upwards. Next, open the storage door and take out the specified number of counterweight plates 13 according to actual usage needs. Place the specified number of counterweight plates 13 into the lifting frame 5. Then, rotate the torsion block 19 to drive the lead screw 18 to rotate, thereby enabling the clamping frame 20 to squeeze and fix the specified number of counterweight plates 13, thus achieving the effect of adjusting the weight of the compaction block 7. Then, flip the door to close it. The single door 21 is engaged with the locking block 22, which is then engaged with the locking groove by the reaction force of the fastening spring 25, thus locking the single door 21. Then, the control unit starts two reduction motors 10 to drive the winding roller 9 to wind up the wire rope 11, which allows the lifting frame 5 to rise to the highest point along the lifting port 4. Then, using the principle of free fall, the lifting frame 5 and the compaction block 7 fall, and their gravitational potential energy is converted into kinetic energy. That is, when the compaction device is working, it relies on the weight of the lifting frame 5 and the compaction block 7 to fall from a certain height. The greater the mass, the greater the kinetic energy converted, and the stronger the impact force on the compacted material, thus more effectively compacting the material.
