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 supporting 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. 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 weakens the friction between the particles of the compacted material, causing the particles to wedge against each other to achieve density. The plate compactor has the advantages of high vibration frequency, good compaction effect, controllable compaction depth, strong adaptability, simple and convenient operation, etc. It is widely used in the compaction of engineering foundations, curbs, and asphalt pavements such as roads, streets, buildings, canals, bridges, etc. The existing plate compactors lack a multi-directional movement mechanism when in use, resulting in relatively poor switching performance. Especially when compacting in a relatively small space, the worker cannot control the plate compactor to flexibly turn, which will affect the normal use of the plate compactor and also affect the subsequent compaction work. Although some plate compactors also have a two-way movement function, they cannot meet the use requirements of multi-directional movement and have certain limitations.

[0003] Therefore, in view of the above technical problems, it is necessary to provide a plate compactor that can be quickly switched.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment 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

[0005] The object of the present invention is to provide a plate compactor capable of rapid reversal, which can solve the problem that the existing plate compactor cannot move in multiple directions.

[0006] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows: A fast-reversing plate compactor comprises: a plate compactor body and a pair of multi-directional moving mechanisms; A tamping plate is installed at the bottom of the plate tamping body; 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, the mounting frame is rotatably connected to a moving wheel, and a spray dust reduction mechanism is installed in the moving wheel.

[0007] In one or more embodiments of the present invention, the L-shaped plate is connected to the ramming plate by a plurality of bolts, so that the multi-directional moving mechanism can be disassembled and assembled, so as to separate the multi-directional moving mechanism from the ramming plate, and facilitate maintenance of the ramming plate and the multi-directional moving mechanism; The length of the L-shaped plate is smaller than that of the ramming plate.

[0008] 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 angles of the connecting member, the mounting frame and the moving wheel; A driven gear is installed on the side wall of the telescopic member.

[0009] In one or more embodiments of the present invention, a first motor is installed on the L-shaped plate, and a driving gear is connected to the output end of the first motor, and the driving gear is meshed with the driven gear. When the first motor is running, the first motor drives the driving gear to rotate. Since the driving gear is meshed 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 rammer body can move using a pair of moving wheels, and the staff does not need to carry the plate rammer body, thereby reducing the burden on the staff.

[0010] In one or more embodiments of the present invention, both ends of the moving wheel are connected to a rotating shaft, and the moving 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 moving wheel to rotate through the rotating shaft. When the pair of moving wheels are in contact with the ground, the rotating moving wheels can be used to drive the plate rammer body to move, thereby reducing the burden of the staff manually pushing the plate rammer body to move.

[0011] 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.

[0013] 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 rammer body is moved by the moving wheels, 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 wheels can be ensured, which facilitates the movement of the moving wheels. When the plate rammer body is changed by the moving wheels, the moving wheels can also be used for rolling to assist the plate rammer body in compacting.

[0014] In one or more embodiments of the present invention, the spray dust reduction mechanism includes a delivery pipe, the delivery pipe is embedded in the moving wheel, and the delivery pipe is used to deliver the spray liquid; 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; 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, the second branch pipe is communicated with the inside of the airbag, and control valves are 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 rammer body can be moved by the moving wheel to achieve the reversal of the plate rammer 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 mist liquid on both sides of the plate rammer body, and use the mist liquid to suppress dust, so as to reduce the dust generated when the plate rammer body is in use.

[0016] Compared with the prior art, the fast-reversing plate rammer of the present invention can realize multi-directional movement of the plate rammer, thereby greatly improving the mobility of the plate rammer. It is particularly suitable for use in relatively narrow environments where it is inconvenient to turn the plate rammer, so as to meet the needs of staff. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in 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 creative work should fall within the scope of protection of the present invention.

[0021] like Figures 1 to 11 As shown, a fast-reversing plate compactor in one embodiment of the present invention includes a plate compactor body 1 and a pair of multi-directional moving mechanisms 2.

[0022] A tamping plate 101 is installed at the bottom of the flat tamping body 1. When the flat tamping body 1 is in operation, the tamping plate 101 can be used for compaction to meet the needs of the staff.

[0023] Preferably, the flat plate rammer body 1 and the rammer plate 101 are both existing technologies, and the connection between the flat plate rammer body 1 and the rammer plate 101 is also existing technologies, so their connection and working principles are not described in detail here.

[0024] In addition, a handle is installed on the plate rammer body 1, and a control unit is installed on the handle to facilitate the staff to control the operation of the plate rammer body 1 and the multi-directional movement of the plate rammer body 1.

[0025] like Figures 1 to 11As shown, a pair of multi-directional moving mechanisms 2 are symmetrically installed on the tamping plate 101. The pair of multi-directional moving mechanisms 2 can enable the plate tamping body 1 to move in multiple directions, so as to improve the movement flexibility of the plate tamping body 1. It is particularly suitable for use in a relatively narrow environment where it is inconvenient for the plate tamping body 1 to turn, so as to meet the use needs of the staff.

[0026] The multi-directional moving mechanism 2 includes an L-shaped plate 201, and the length of the L-shaped plate 201 is less than the length of the ramming plate 101. The L-shaped plate 201 is connected to the ramming plate 101 by a plurality of bolts, so that the multi-directional moving mechanism 2 can be disassembled and assembled, so that the multi-directional moving mechanism 2 can be separated from the ramming plate 101, and the ramming plate 101 and the multi-directional moving mechanism 2 can be maintained conveniently.

[0027] like Figures 1 to 11 As shown, a first motor 2011 is installed on the L-shaped plate 201 , and a driving gear 2012 is connected to the output end of the first motor 2011 , and the driving gear 2012 is meshed with the driven gear 2022 .

[0028] When the first motor 2011 is running, the first motor 2011 drives the driving gear 2012 to rotate. Since the driving gear 2012 is meshed 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. Fig. 9 and Fig.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.

[0029] 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 flat tamping body 1 can be stably moved using a pair of moving wheels 205.

[0030] A telescopic member 202 is mounted 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 angles of the connecting member 203, the mounting frame 204 and the moving wheel 205. Fig. 9 and Fig.11 Angle shown.

[0031] 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.

[0032] In addition, a driven gear 2022 is installed on the side wall of the telescopic member 202, and the driven gear 2022 is meshed with the driving gear 2012, so that the rotation of the driving gear 2012 can drive the rotation of the driven gear 2022, and then drive 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 tamping body 1.

[0033] 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 frame 204, and the mounting frame 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 flat plate rammer body 1 to move, so as to achieve multi-angle steering of the flat plate rammer body 1.

[0034] like Figures 1 to 11 As shown, the connector 203 is provided with a dust suppressant 2031, which is a biological dust suppressant, such as a biological dust suppressant made of guar gum hydroxypropyltrimethylol, ammonium chloride, vegetable oil acid, glycerol, emulsifier, polyvinyl alcohol, isooctyl oleate, potassium hydroxide and water. This suppressant is a colorless liquid, and has the advantages of being non-corrosive and non-polluting, and having the functions of condensation, moisture absorption and dust prevention. A suction pipe is connected between the connecting piece 203 and the minimum diameter of the venturi tube 303, and a check valve is installed on the suction pipe.

[0035] The water pump 302 is operated to extract the spray liquid 301 in the water tank 3 and transport it through the first telescopic hose, the venturi tube 303 and the second telescopic hose 304. When the spray liquid 301 flows at a high speed in the venturi tube 303, a negative pressure is formed in the suction pipe, i.e., the Venturi effect. At this time, the dust reduction liquid 2031 in the connector 203 enters the venturi tube 303 through the suction pipe and is mixed and transported with the spray liquid 301. The dust reduction effect can be further improved by mixing the spray liquid 301 with the dust reduction liquid 2031.

[0036] In addition, both ends of the moving wheel 205 are connected to a rotating shaft, and the moving wheel 205 is rotatably connected to the mounting frame 204 through a pair of rotating shafts. A second motor 206 is installed on the mounting frame 204, and the second motor 206 is connected to one of the rotating shafts. When the second motor 206 is running, the second motor 206 can drive the moving wheel 205 to rotate through the rotating shaft. When the pair of moving wheels 205 are in contact with the ground, the rotating moving wheels 205 can drive the plate tamping body 1 to move, thereby reducing the burden of the staff manually pushing the plate tamping body 1 to move.

[0037] 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.

[0038] Preferably, an angle sensor is installed on the outer side 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.

[0039] like Figures 1 to 11 As shown, the moving wheel 205 is provided with a first cavity 2051 and a second cavity 2052, and the side wall of the moving wheel 205 is provided with a plurality of inclined holes 2053, which are all arranged on the same straight line, and the second cavity 2052 is connected to the outside through the plurality of inclined holes 2053. The spray liquid 301 in the moving wheel 205 can be discharged through the first cavity 2051, the second cavity 2052 and the inclined holes 2053 in sequence. When the spray liquid 301 is discharged, mist liquid can be sprayed on both sides of the plate rammer body 1, and the mist liquid is used to reduce dust, thereby greatly reducing the dust generated when the plate rammer body 1 is in operation.

[0040] A connecting pipe 208 is installed in the moving wheel 205 , and the first cavity 2051 is connected with 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 .

[0041] In addition, an airbag 2054 is installed on the inner wall of the second cavity 2052, and a plurality of elastic protrusions 2055 are connected to the airbag 2054, and the plurality of elastic protrusions 2055 correspond to the plurality of inclined holes 2053 respectively. When the spray liquid 301 enters the airbag 2054, the airbag 2054 can be expanded, and the expanded airbag 2054 can make the elastic protrusions 2055 approach the inclined holes 2053 and block the inclined holes 2053. When the plate tamping body 1 is moved by a pair of moving wheels 205, by blocking the inclined holes 2053, foreign particles can be prevented from entering the second cavity 2052 through the inclined holes 2053, and the flatness of the outer wall of the moving wheel 205 can be ensured, which facilitates the movement of the moving wheel 205, and when the moving wheel 205 is used to reverse the plate tamping body 1, the moving wheel 205 can also be used for rolling to assist the plate tamping body 1 in compaction.

[0042] 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 change the direction of the plate tamping body 1, the moving wheel 205 will be out of contact with the ground. Figure 1 In the state shown, at this time, the dust generated when the plate rammer body 1 is in operation can be reduced by using the spray dust reduction mechanism in the moving wheel 205.

[0043] The spray dust reduction mechanism includes a delivery pipe 2056 , which is embedded in the moving wheel 205 , and is used to deliver the spray liquid 301 to the moving wheel 205 .

[0044] In addition, one end of the delivery pipe 2056 passes through the rotating shaft and is disposed in the sealing cover 207 , and the spray liquid 301 in the sealing cover 207 can enter the moving wheel 205 through the delivery pipe 2056 .

[0045] 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 .

[0046] 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 flat rammer body 1 to achieve reversal of the flat rammer body 1.

[0047] 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 a plurality of inclined holes 2053, so as to form mist liquid on both sides of the plate rammer body 1, and utilize the mist liquid to suppress dust, so as to reduce the dust generated when the plate rammer body 1 is in use.

[0048] 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 spray liquid 301 and the dust reduction liquid 2031 flow in the first cavity 2051 , the reinforcing columns 2059 can also play a mixing role.

[0049] 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 .

[0050] The water tank 3 is provided with a spray liquid 301 and a water pump 302. The spray liquid 301 is water. The water pump 302 is placed in the spray liquid 301. The output end of the water pump 302 is connected to a first telescopic hose, which will not affect the angular rotation of the moving wheel 205. The first telescopic hose is connected to a venturi tube 303, and the venturi tube 303 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 running, the water pump 302 can extract the spray liquid 301, and transport the spray liquid 301 to the sealing cover 207 through the venturi tube 303 and the second telescopic hose 304, and finally transport it to the moving wheel 205.

[0051] In addition, both the connecting piece 203 and the water tank 3 are provided with an observation plate and a replenishing pipe, so as to facilitate replenishing the dust reduction liquid 2031 into the connecting piece 203 and replenishing the spraying liquid 301 into the water tank 3 .

[0052] 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 .

[0053] When the plate compactor body 1 is working, the telescopic member 202 is in a retracted state, at which time the moving wheel 205 is out of contact with the ground. Figure 1The water pump 302 is operated, and only the control valve on the first branch pipe 2057 is opened. The water pump 302 extracts the spray liquid 301 in 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, and the spray liquid 301 in the first cavity 2051 enters the second cavity 2052 through the connecting pipe 208, and then is discharged through the inclined hole 2053, which is used to spray mist liquid on both sides of the plate rammer body 1, and use the mist liquid to reduce dust, thereby greatly reducing the dust generated when the plate rammer body 1 is in operation.

[0054] When the spray liquid 301 flows at a high speed in the venturi tube 303, negative pressure is formed in the suction pipe. At this time, the dust reduction liquid 2031 in the connecting piece 203 enters the venturi tube 303 through the suction pipe and is mixed and transported with the spray liquid 301. In the first cavity 2051, several reinforcing columns 2059 can be used for remixing, and finally discharged through the inclined hole 2053, which can further improve the dust reduction effect.

[0055] When the moving wheel 205 is needed to perform lateral reversal, only the control valve on the second branch pipe 2058 is opened, and the spray liquid 301 extracted from the water tank 3 enters the airbag 2054 through the delivery pipe 2056 and the second branch pipe 2058, so that the airbag 2054 expands. 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, which can prevent foreign particles from entering the second cavity 2052 through the inclined hole 2053. At the same time, the flatness of the outer wall of the moving wheel 205 can be ensured, which facilitates the movement of the moving wheel 205, and when the moving wheel 205 is used to perform reversal movement on the plate tamping body 1, the moving wheel 205 can also be used for rolling to assist the plate tamping body 1 in compaction.

[0056] 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 tamping body 1, so that the tamping 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 tamping body 1 to move laterally, so as to reduce the burden of the staff to manually push the plate tamping body 1 to move.

[0057] 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 position of Figure 1 The control valves on the first branch pipe 2057 and the second branch pipe 2058 are opened, and 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 shrink, 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, avoiding waste of the spray liquid 301.

[0058] When the plate tamping body 1 needs to move to other angles, such as Fig.11 In addition 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 meshed 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 wheel 205 to rotate. Fig.11 At this time, a pair of moving wheels 205 can be used to move in multiple directions to meet the use needs of the staff.
