Description

Technical Field

[0001] The invention belongs to the technical field of plate compactors, and in particular relates to a plate compactor capable of rapid reversal. Background Art

[0002] A plate compactor is a mechanical device used to compact land, asphalt, concrete and other materials. It is mainly composed of a power unit, a transmission mechanism, a vibrator, a tamping plate, a support plate and a spring. The power unit drives the eccentric shaft of the vibrator to rotate through the transmission mechanism to generate an exciting force, and the exciting force is decomposed into a motion component and a compaction component. The motion component can make the equipment move horizontally, and the compaction component is transmitted to the compacted material through the tamping plate, which destroys the original structure of the compacted material and reduces the friction between the particles of the compacted material, causing the particles to wedge against each other to achieve density. Plate compactors have the advantages of high vibration frequency, good compaction effect, controllable compaction depth, strong adaptability, and simple and convenient operation. They are widely used in the compaction of engineering foundations, curbs, and asphalt pavements such as roads, streets, buildings, canals, and bridges.

[0003] Existing plate compactors lack a multi-directional mechanism, resulting in relatively poor switching performance. This is especially true when compacting in confined spaces, as workers cannot flexibly control the plate compactor, which in turn affects the proper operation of the compactor and subsequent compaction operations. While some plate compactors have bidirectional movement, they cannot meet the multi-directional requirements and present certain limitations.

[0004] Therefore, in order to solve the above technical problems, it is necessary to provide a plate compactor that can be quickly switched.

[0005] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0006] The object of the present invention is to provide a plate compactor capable of rapid reversal, which can solve the problem that existing plate compactors cannot move in multiple directions.

[0007] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0008] A fast-reversing plate compactor comprises a plate compactor body and a pair of multi-directional moving mechanisms;

[0009] A ramming plate is installed at the bottom of the plate ramming body;

[0010] A pair of multi-directional moving mechanisms are symmetrically installed on the ramming plate, and the multi-directional moving mechanism includes an L-shaped plate, a telescopic part is installed on the L-shaped plate, the free end of the telescopic part is connected to a connecting part, the lower bottom wall of the connecting part is fixedly connected to a mounting frame, and a moving wheel is rotatably connected to the mounting frame, and a spray dust reduction mechanism is installed in the moving wheel.

[0011] In one or more embodiments of the present invention, the L-shaped plate is connected to the ramming plate by a plurality of bolts, which enables the multi-directional moving mechanism to be disassembled and assembled, so as to separate the multi-directional moving mechanism from the ramming plate, thereby facilitating maintenance of the ramming plate and the multi-directional moving mechanism;

[0012] The length of the L-shaped plate is smaller than that of the ramming plate.

[0013] In one or more embodiments of the present invention, a bearing is connected between the telescopic member and the L-shaped plate to facilitate the rotation of the telescopic member so as to adjust the angle of the connecting member, the mounting frame and the moving wheel;

[0014] A driven gear is installed on the side wall of the telescopic member.

[0015] In one or more embodiments of the present invention, a first motor is mounted on the L-shaped plate, and a driving gear is connected to the output end of the first motor, and the driving gear is engaged with the driven gear. When the first motor is running, the first motor drives the driving gear to rotate. Since the driving gear is engaged with the driven gear, the driven gear and the telescopic member can be driven to rotate, so as to adjust the angles of the connecting member, the mounting frame and the moving wheel, so that the plate compactor body can move using a pair of moving wheels, and the staff does not need to carry the plate compactor body, thereby reducing the burden on the staff.

[0016] In one or more embodiments of the present invention, both ends of the movable wheel are connected to a rotating shaft, and the movable wheel is rotatably connected to the mounting frame through a pair of rotating shafts. A second motor is installed on the mounting frame, and the second motor is connected to one of the rotating shafts. When the second motor is running, the second motor can drive the movable wheel to rotate through the rotating shaft. When the pair of movable wheels are in contact with the ground, the rotating movable wheels can drive the plate compactor body to move, thereby reducing the burden of the staff manually pushing the plate compactor body to move.

[0017] In one or more embodiments of the present invention, a sealing cover is installed on the mounting frame, and the sealing cover is arranged on the other rotating shaft to guide the spray liquid into the conveying pipe.

[0018] In one or more embodiments of the present invention, a first cavity and a second cavity are provided in the moving wheel, a plurality of inclined holes are provided on the side wall of the moving wheel, and the plurality of inclined holes are all provided on the same straight line. The second cavity is connected to the outside through the plurality of inclined holes. The spray liquid in the moving wheel can be discharged in sequence through the first cavity, the second cavity, and the inclined holes, so that the mist liquid is sprayed on both sides of the plate compactor body. The mist liquid is used to suppress dust, thereby significantly reducing the dust generated during the operation of the plate compactor body.

[0019] A connecting pipe is installed in the moving wheel, and the first cavity is connected with the second cavity through the connecting pipe. The spray liquid in the first cavity can enter the second cavity through the connecting pipe.

[0020] In one or more embodiments of the present invention, an airbag is installed on the inner wall of the second cavity, and a plurality of elastic protrusions are connected to the airbag, and the plurality of elastic protrusions respectively correspond to the plurality of inclined holes. When the spray liquid enters the airbag, the airbag can be expanded, and the expanded airbag can make the elastic protrusions approach the inclined holes and block the inclined holes. When the plate compactor body is moved by the moving wheel, external particles are prevented from entering the second cavity through the inclined holes. At the same time, the flatness of the outer wall of the moving wheel can be ensured, which facilitates the movement of the moving wheel. When the plate compactor body is reversed by the moving wheel, the moving wheel can also be used for rolling to assist the plate compactor body in compacting.

[0021] In one or more embodiments of the present invention, the spray dust reduction mechanism includes a delivery pipe, which is embedded in the moving wheel and is used to deliver the spray liquid;

[0022] One end of the delivery pipe passes through the rotating shaft and is arranged in the sealing cover, and the spray liquid in the sealing cover can enter the moving wheel through the delivery pipe;

[0023] The delivery pipe is connected to a first branch pipe and a second branch pipe, the first branch pipe is communicated with the first cavity, and the second branch pipe is communicated with the inside of the airbag, and a control valve is installed on the first branch pipe and the second branch pipe. When the control valve on the second branch pipe is opened, the spray liquid in the delivery pipe will enter the airbag and expand the airbag until the elastic protrusion can block the inclined hole, so that the plate compactor body can be moved by the moving wheel to achieve the reversal of the plate compactor body; when the control valve on the first branch pipe is opened, the spray liquid in the delivery pipe will enter the first cavity, then enter the second cavity through the connecting pipe, and finally be discharged through a plurality of inclined holes, so as to form a mist liquid on both sides of the plate compactor body, and use the mist liquid to reduce dust, so as to reduce the dust generated when the plate compactor body is in use.

[0024] In one or more embodiments of the present invention, a water tank is mounted on the L-shaped plate, and the water tank is used to store the spray liquid and the water pump;

[0025] The water tank is provided with spray liquid and a water pump, the water pump is placed in the spray liquid, the water pump is connected to a venturi tube, the venturi tube is connected to a second telescopic hose, one end of the second telescopic hose is connected to the sealing cover, when the water pump is running, the water pump can extract the spray liquid and transport the spray liquid through the venturi tube and the second telescopic hose into the sealing cover, and finally transport it to the moving wheel.

[0026] Compared with the existing technology, the fast-reversing plate compactor of the present invention can realize multi-directional movement of the plate compactor, thereby greatly improving the movement flexibility of the plate compactor. It is particularly suitable for use in relatively narrow environments where it is inconvenient to turn the plate compactor, so as to meet the usage needs of staff. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments 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 should fall within the scope of protection of the present invention.

[0042] like Figures 1 to 11 As shown, a fast-reversing plate compactor according to one embodiment of the present invention includes a plate compactor body 1 and a pair of multi-directional moving mechanisms 2 .

[0043] Among them, a ramming plate 101 is installed at the bottom of the plate ramming body 1. When the plate ramming body 1 is running, the ramming plate 101 can be used to perform ramming to meet the use needs of the staff.

[0044] Preferably, the plate rammer body 1 and the rammer plate 101 are both existing technologies, and the connection between the plate rammer body 1 and the rammer plate 101 is also existing technologies. Therefore, their connection and working principles are not described in detail here.

[0045] In addition, a handle is installed on the plate compactor body 1, and a control unit is installed on the handle to facilitate the staff to control the operation of the plate compactor body 1 and the multi-directional movement of the plate compactor body 1.

[0046] like Figures 1 to 11 As shown, a pair of multi-directional moving mechanisms 2 are symmetrically installed on the ramming plate 101. The pair of multi-directional moving mechanisms 2 can be used to make the plate ramming body 1 move in multiple directions, so as to improve the movement flexibility of the plate ramming body 1. It is particularly suitable for use in a relatively narrow environment where it is inconvenient for the plate ramming body 1 to turn, so as to meet the use needs of the staff.

[0047] The multi-directional movement mechanism 2 includes an L-shaped plate 201, which is shorter than the ramming plate 101. The L-shaped plate 201 is connected to the ramming plate 101 by a plurality of bolts, which allows the multi-directional movement mechanism 2 to be disassembled and assembled, so that the multi-directional movement mechanism 2 can be separated from the ramming plate 101, facilitating maintenance of the ramming plate 101 and the multi-directional movement mechanism 2.

[0048] like Figures 1 to 11 As shown, a first motor 2011 is mounted on the L-shaped plate 201 , and an output end of the first motor 2011 is connected to a driving gear 2012 , which is meshed with a driven gear 2022 .

[0049] When the first motor 2011 is running, the first motor 2011 drives the driving gear 2012 to rotate. Since the driving gear 2012 is engaged with the driven gear 2022, the driven gear 2022 and the telescopic member 202 can be driven to rotate, so as to adjust the angles of the connecting member 203, the mounting frame 204 and the moving wheel 205. Figure 9 and Figure 11 The angle shown allows the plate rammer body 1 to move using a pair of moving wheels 205, including lateral movement and movement in the front and rear directions during operation, thereby improving the mobility of the plate rammer body 1. It is particularly suitable for use in relatively narrow environments where it is inconvenient for the plate rammer body 1 to turn, so as to meet the usage needs of the staff.

[0050] Preferably, the first motor 2011 is a servo motor, which can achieve precise control of the rotation angle of the driving gear 2012. At the same time, when the first motor 2011 is not running, the telescopic member 202 can be self-locked, that is, the connecting member 203 connected to the telescopic member 202 can remain fixed and will not rotate, so as to ensure that the plate compactor body 1 can be stably moved using a pair of moving wheels 205.

[0051] Among them, the telescopic member 202 is installed on the L-shaped plate 201, and a bearing 2021 is connected between the telescopic member 202 and the L-shaped plate 201 to facilitate the rotation of the telescopic member 202 so as to adjust the angle of the connecting member 203, the mounting frame 204 and the moving wheel 205. Figure 9 and Figure 11 Angle shown.

[0052] Preferably, the output end of the telescopic member 202 is a polygonal column, so that when the telescopic member 202 rotates, the polygonal column can drive the connecting member 203, the mounting frame 204 and the moving wheel 205 to rotate.

[0053] In addition, a driven gear 2022 is installed on the side wall of the telescopic member 202, and the driven gear 2022 is engaged with the driving gear 2012, so that the rotation of the driving gear 2012 drives the rotation of the driven gear 2022, and then drives the telescopic member 202 to rotate, so as to adjust the angle of the moving wheel 205 and improve the multi-directional movement and flexibility of the plate compactor body 1.

[0054] Specifically, the free end of the telescopic member 202 is connected to a connecting member 203, the lower bottom wall of the connecting member 203 is fixedly connected to a mounting bracket 204, and the mounting bracket 204 is rotatably connected to a moving wheel 205. When a pair of moving wheels 205 are in contact with the ground, the rotation of the moving wheels 205 can drive the plate compactor body 1 to move, so as to realize multi-angle steering of the plate compactor body 1.

[0055] like Figures 1 to 11 As shown, the connector 203 is provided with a dust suppression liquid 2031. The dust suppression liquid 2031 is a biological dust suppressant, such as a biological dust suppressant made from guar gum hydroxypropyltrimonium chloride, ammonium chloride, vegetable oil acid, glycerol, emulsifier, polyvinyl alcohol, isooctyl oleate, potassium hydroxide, and water. This inhibitor is a colorless liquid with the advantages of being non-corrosive and non-polluting, and having condensation, moisture absorption, and dust-proofing properties.

[0056] A suction pipe is connected between the connecting piece 203 and the minimum diameter portion of the venturi tube 303 , and a check valve is installed on the suction pipe.

[0057] The water pump 302 operates, drawing spray liquid 301 from the water tank 3 and transporting it through the first telescopic hose, the Venturi tube 303, and the second telescopic hose 304. The high-speed flow of the spray liquid 301 within the Venturi tube 303 creates a negative pressure within the suction pipe, a phenomenon known as the Venturi effect. At this point, the dust suppression liquid 2031 within the connector 203 enters the Venturi tube 303 through the suction pipe, mixing with the spray liquid 301 and transporting it. This mixing of the spray liquid 301 and the dust suppression liquid 2031 further enhances the dust reduction effect.

[0058] Furthermore, each end of the moving wheel 205 is connected to a rotating shaft. The moving wheel 205 is rotatably connected to the mounting frame 204 via a pair of rotating shafts. A second motor 206 is mounted on the mounting frame 204 and is connected to one of the rotating shafts. When the second motor 206 is running, the second motor 206 drives the moving wheel 205 to rotate via the rotating shaft. When the pair of moving wheels 205 come into contact with the ground, the rotating moving wheels 205 can drive the plate compactor body 1 to move, thereby reducing the burden on the operator to manually push the plate compactor body 1.

[0059] Furthermore, a sealing cover 207 is installed on the mounting frame 204, and the sealing cover 207 is arranged on another rotating shaft, that is, Figure 5 In the state shown, the spray liquid 301 can be introduced from the water tank 3 into the delivery pipe 2056 to avoid leakage of the spray liquid 301.

[0060] Preferably, an angle sensor is installed on the outer wall of the moving wheel 205 to control the rotation angle of the moving wheel 205, that is, when spraying dust is required, it can ensure that the inclined hole 2053 can be on the lower side, that is, Figure 4 Position shown.

[0061] like Figures 1 to 11 As shown, the moving wheel 205 is provided with a first cavity 2051 and a second cavity 2052. The sidewall of the moving wheel 205 is provided with a plurality of inclined holes 2053, all arranged in a straight line. The second cavity 2052 is connected to the outside world through the inclined holes 2053. The spray liquid 301 within the moving wheel 205 can be discharged sequentially through the first cavity 2051, the second cavity 2052, and the inclined holes 2053. When the spray liquid 301 is discharged, it can spray a mist of liquid on both sides of the plate compactor body 1, using the mist to suppress dust, thereby significantly reducing the dust generated during the operation of the plate compactor body 1.

[0062] A connecting pipe 208 is installed in the moving wheel 205 , and the first cavity 2051 is connected to the second cavity 2052 through the connecting pipe 208 . The spray liquid 301 in the first cavity 2051 can enter the second cavity 2052 through the connecting pipe 208 .

[0063] In addition, an airbag 2054 is mounted on the inner wall of the second cavity 2052. Several elastic protrusions 2055 are connected to the airbag 2054, and the several elastic protrusions 2055 correspond to the several inclined holes 2053. When the spray liquid 301 enters the airbag 2054, the airbag 2054 expands. The expanded airbag 2054 causes the elastic protrusions 2055 to approach the inclined holes 2053 and block the inclined holes 2053. When the plate compactor body 1 is moved by the pair of moving wheels 205, blocking the inclined holes 2053 prevents foreign particles from entering the second cavity 2052 through the inclined holes 2053. This also ensures the smoothness of the outer wall of the moving wheels 205, facilitating movement of the moving wheels 205. Furthermore, when the moving wheels 205 are used to reverse the direction of the plate compactor body 1, the moving wheels 205 can also be used to roll the plate compactor body 1, assisting in compaction.

[0064] like Figures 1 to 11 As shown, a spray dust reduction mechanism is installed in the moving wheel 205. When the moving wheel 205 is not needed to reverse the plate compactor body 1, the moving wheel 205 will be out of contact with the ground, that is, Figure 1 In the state shown, at this time, the dust reduction mechanism in the movable wheel 205 can be used to reduce the dust generated when the plate compactor body 1 is in operation.

[0065] The spray dust reduction mechanism includes a delivery pipe 2056 , which is embedded in the moving wheel 205 . The delivery pipe 2056 is used to deliver the spray liquid 301 to the moving wheel 205 .

[0066] In addition, one end of the delivery pipe 2056 passes through the rotating shaft and is disposed in the sealing cover 207 , and the spraying liquid 301 in the sealing cover 207 can enter the moving wheel 205 through the delivery pipe 2056 .

[0067] Specifically, the delivery pipe 2056 is connected to a first branch pipe 2057 and a second branch pipe 2058. The first branch pipe 2057 is connected to the first cavity 2051, and the second branch pipe 2058 is connected to the inside of the airbag 2054. Control valves are installed on the first branch pipe 2057 and the second branch pipe 2058.

[0068] When the control valve on the second branch pipe 2058 is opened, the spray liquid 301 in the delivery pipe 2056 will enter the airbag 2054 and expand the airbag 2054 until the elastic protrusion 2055 on the airbag 2054 can block the inclined hole 2053, and then the telescopic part 202 is controlled to extend so that the moving wheel 205 can contact the ground. The pair of moving wheels 205 can be used to move the plate compactor body 1 to achieve reversal of the plate compactor body 1.

[0069] When the control valve on the first branch pipe 2057 is opened, the spray liquid 301 in the delivery pipe 2056 will enter the first cavity 2051, then enter the second cavity 2052 through the connecting pipe 208, and finally be discharged through the plurality of inclined holes 2053, so as to form a mist liquid on both sides of the plate compactor body 1, and utilize the mist liquid to suppress dust, so as to reduce the dust generated when the plate compactor body 1 is in use.

[0070] In addition, a plurality of reinforcing columns 2059 are installed in the first cavity 2051 . The reinforcing columns 2059 are used to increase the overall strength of the moving wheel 205 . At the same time, when the spraying liquid 301 and the dust reduction liquid 2031 flow in the first cavity 2051 , the reinforcing columns 2059 can also play a mixing role.

[0071] like Figures 1 to 11 As shown, a water tank 3 is installed on the L-shaped plate 201 , and the water tank 3 is used to store the spray liquid 301 and the water pump 302 .

[0072] The water tank 3 contains a spray liquid 301 and a water pump 302. The spray liquid 301 is water, and the water pump 302 is placed within the spray liquid 301. The output end of the water pump 302 is connected to a first telescopic hose, which does not affect the angular rotation of the moving wheel 205. The first telescopic hose is connected to a venturi tube 303, which is connected to a second telescopic hose 304. One end of the second telescopic hose 304 is connected to the sealing cover 207. When the water pump 302 is in operation, it draws the spray liquid 301 and delivers it through the venturi tube 303 and the second telescopic hose 304 into the sealing cover 207, and finally to the moving wheel 205.

[0073] In addition, both the connecting piece 203 and the water tank 3 are provided with an observation plate and a replenishing pipe, which facilitates replenishing the dust suppression liquid 2031 into the connecting piece 203 and replenishing the spraying liquid 301 into the water tank 3.

[0074] During specific use, the plate rammer body 1 is operated, and the plate rammer body 1 can perform compaction work through the rammer plate 101 .

[0075] When the plate compactor body 1 is working, the telescopic member 202 is in a retracted state. At this time, the moving wheel 205 is out of contact with the ground. Figure 1The state shown is shown. When the water pump 302 is running and only the control valve on the first branch pipe 2057 is opened, the water pump 302 draws spray liquid 301 from the water tank 3 and delivers the spray liquid 301 to the sealing cover 207 through the first telescopic hose, the venturi tube 303, and the second telescopic hose 304. The spray liquid 301 in the sealing cover 207 then enters the first cavity 2051 through the delivery pipe 2056 and the first branch pipe 2057. The spray liquid 301 in the first cavity 2051 enters the second cavity 2052 through the connecting pipe 208 and is then discharged through the inclined hole 2053. This sprays a mist of liquid onto both sides of the plate compactor body 1, utilizing the mist to suppress dust, thereby significantly reducing the dust generated during the operation of the plate compactor body 1.

[0076] When the spray liquid 301 flows at high speed within the Venturi tube 303, a negative pressure is formed within the suction pipe. At this point, the dust suppression liquid 2031 within the connector 203 enters the Venturi tube 303 through the suction pipe and is mixed with the spray liquid 301. Within the first cavity 2051, several reinforcing columns 2059 can be used for further mixing before the liquid is discharged through the inclined hole 2053, further enhancing the dust suppression effect.

[0077] When the moving wheel 205 is needed for lateral reversal, only the control valve on the second branch pipe 2058 is opened. The spray liquid 301 drawn from the water tank 3 enters the airbag 2054 through the delivery pipe 2056 and the second branch pipe 2058, causing the airbag 2054 to expand. When the elastic protrusion 2055 on the airbag 2054 blocks the inclined hole 2053, the water tank 3 is stopped and the control valve on the second branch pipe 2058 is closed. This prevents foreign particles from entering the second cavity 2052 through the inclined hole 2053. This also ensures the smoothness of the outer wall of the moving wheel 205, facilitating its movement. Furthermore, when the moving wheel 205 is used to reverse the direction of the plate compactor body 1, the moving wheel 205 can also be used for rolling, assisting the plate compactor body 1 in compacting.

[0078] Then the telescopic member 202 is controlled to extend, and the telescopic member 202 drives the connecting member 203, the mounting frame 204 and the moving wheel 205 to move downward until the moving wheel 205 contacts the ground, and props up the plate compactor body 1, so that the ramming plate 101 is out of contact with the ground. Figure 4 The second motor 206 is operated, and the second motor 206 can drive the moving wheel 205 to rotate through the rotating shaft, and the rotating moving wheel 205 can drive the plate compactor body 1 to move laterally, so as to reduce the burden of the staff to manually push the plate compactor body 1 to move.

[0079] When the lateral movement of the plate tamping body 1 is completed, the telescopic member 202 is controlled to retract, so that the tamping plate 101 contacts the ground, the moving wheel 205 is out of contact with the ground, and the angle sensor on the side wall of the moving wheel 205 is used to make the inclined hole 2053 return to the lower side, that is, to return to the Figure 1 When the control valves on the first branch pipe 2057 and the second branch pipe 2058 are opened, the spray liquid 301 in the airbag 2054 enters the first cavity 2051 through the second branch pipe 2058, the delivery pipe 2056, and the first branch pipe 2057, thereby causing the airbag 2054 to contract and the elastic protrusion 2055 to break away from the oblique hole 2053. At the same time, the spray liquid 301 discharged from the airbag 2054 can also be used for spraying and dust reduction, thereby avoiding waste of the spray liquid 301.

[0080] When the plate compactor body 1 needs to move to other angles, such as Figure 11 The angle shown in FIG2 is not limited to blocking the inclined hole 2053 and controlling the extension of the telescopic member 202. When the plate compactor body 1 is supported by a pair of moving wheels 205, the first motor 2011 needs to be operated. The first motor 2011 drives the driving gear 2012 to rotate. Since the driving gear 2012 is engaged with the driven gear 2022, the driven gear 2022 and the telescopic member 202 can be driven to rotate. The telescopic member 202 can drive the connecting member 203, the mounting frame 204 and the moving wheels 205 to rotate. Figure 11 At this time, a pair of moving wheels 205 can be utilized to carry out multi-directional movement to meet the use needs of the staff.
