Description

Technical Field

[0001] The invention relates to the technical field of concrete vibrating equipment, and in particular to a concrete vibrating device. Background Art

[0002] After mixing, transporting, and pouring, concrete often contains bubbles formed by entrained air. The purpose of the vibration process is to expel the bubbles in the concrete, reduce porosity, make the concrete dense, and ensure the quality of the structure. For most water conservancy and hydropower construction projects, due to the tight schedule and heavy workload, traditional small handheld vibrating equipment can no longer meet construction needs. Self-propelled vibrators have high efficiency and good construction quality, which can greatly reduce the labor intensity of vibration construction. They have gradually replaced handheld vibrators and become the mainstream vibrating equipment in the pouring of hydropower dams. However, during the pouring of hydropower dams, there are no conditions for building running tracks on both sides of the unsolidified concrete. Therefore, a concrete vibrating device is used to vibrate the concrete of water conservancy and hydropower construction projects to meet the construction needs of hydropower dams. Summary of the Invention

[0003] The invention provides a concrete vibrating device, which can automatically drive a vibrating rod to efficiently vibrate the concrete on an unsolidified concrete dam body, thereby meeting the construction requirements of dam pouring in hydropower projects.

[0004] The present invention is achieved through the following technical solutions:

[0005] The present invention provides a concrete vibrating device, comprising a vibrating mechanism, a chassis and a mechanical arm, wherein the vibrating mechanism is mounted on the chassis through the mechanical arm; the vibrating mechanism comprises a vibrating rod body, a vibrating disk and a vibrating cylinder, the vibrating rod body is a hollow structure, a vibrating plate is mounted in the vibrating rod body, the upper end of the vibrating plate is fixedly connected to the vibrating rod body, and the lower end is suspended from the lower end of the vibrating rod body; vibrating heads are respectively provided on both sides of the length direction of the vibrating plate, the vibrating cylinder is adapted to be equipped with a vibrating piston, the side of the vibrating piston facing the vibrating plate is a normal pressure side, and is fixedly connected to a vibrating hammer, and the end of the vibrating cylinder away from the vibrating plate is connected to an alternating pressurized hydraulic source; the middle part of the mechanical arm is connected to the chassis, and the hydraulic source and the vibrating rod body are respectively arranged at both ends of the mechanical arm; wherein, driven by the hydraulic source, the vibrating hammer can hammer the side wall of the vibrating plate.

[0006] The concrete vibrating device provided by the present invention comprises a vibrating mechanism, a chassis and a mechanical arm. The vibrating mechanism is installed on the chassis through the mechanical arm, and the vibrating mechanism comprises a vibrating rod body, a vibrating plate and a vibrating cylinder. The vibrating mechanism is provided with a vibrating plate and a vibrating cylinder in a hollow vibrating rod body. The upper end of the vibrating plate is fixedly connected to the vibrating rod body, the lower end is suspended from the lower end of the vibrating rod body, and vibrating heads are respectively provided on both sides in the length direction. The vibrating cylinder is adapted to be equipped with a vibrating piston. The side of the vibrating piston facing the vibrating plate is a normal pressure side and is fixedly connected with a vibrating hammer. By inputting alternating pressure to the vibrating cylinder, The hydraulic source drives the vibrating hammer to hammer the side wall of the vibration plate. At the same time, since the side of the vibrating piston facing the vibration plate is in a normal pressure state, the negative pressure in the vibrating cylinder when the hydraulic oil flows back can drive the vibrating piston to reset, so that the vibrating hammer periodically hammers the vibration plate, thereby driving the vibrating head to impact the corresponding side wall of the vibrating rod body, thereby driving the vibrating rod body to vibrate, and then the chassis drives the vibrating mechanism to move on the concrete, so that it can automatically drive the vibrating rod body to efficiently vibrate the concrete on the unsolidified concrete dam body, meeting the construction needs of hydropower project dam pouring.

[0007] In addition, existing concrete vibrators are driven by a flexible shaft, resulting in a low transmission modulation rate and high energy loss. They are only suitable for fixed-frequency vibration and are difficult to adjust according to the on-site concrete distribution and concrete compaction degree. To ensure the quality of the concrete structure, repeated vibration cycles are required, resulting in low vibration efficiency and a shortened construction period. Therefore, compared to vibrators in which a flexible shaft drives an eccentric wheel, the present invention has, on the one hand, high transmission efficiency, is not affected by the bending of the connecting pipes, has low energy loss, and a high transmission modulation rate. By changing the alternating frequency of the hydraulic source, the vibration frequency of the vibrating rod can be changed to adjust according to the on-site concrete distribution and concrete compaction degree, thereby ensuring the quality of the concrete structure, increasing vibration efficiency, and shortening the construction period. On the other hand, under the condition of a constant alternating frequency of the hydraulic source, the vibrating punch vibrates the vibrating plate at a certain frequency, causing the frequency of the vibrating plate to periodically vary from high to low within a set frequency range. This causes the vibration frequency of the vibrating rod to also periodically vary from high to low, thereby achieving variable-frequency vibration within a certain range, thereby preventing water bleeding and sand and gravel stratification in the concrete.

[0008] In an optional embodiment, the vibration mechanism includes: a rotating drive block, which is a hollow structure, and the vibration cylinder is connected to the inner cavity of the rotating drive block; a support shaft, one end of which is sealed and inserted inside the rotating drive block, and the rotating drive block can rotate around the support shaft; a hydraulic pipe, one end of which is connected to the inner cavity of the rotating drive block through the support shaft, and is used to connect to an alternating pressurized hydraulic source; wherein the upper end of the vibrating rod body is coaxially and fixedly connected to the rotating drive block.

[0009] It can be seen that the upper end of the vibrating rod body is coaxially fixedly connected to the rotating drive block, and one end of the support shaft is sealed and inserted inside the drive. The driving component can drive the vibrating plate body to rotate around the support shaft, thereby vibrating the concrete around the vibrating rod body, improving the vibration efficiency, and making the rotating drive block rotate around the support shaft.

[0011] In an optional embodiment, the vibrating mechanism further includes a driving wheel, which abuts against the outside of the flexible sleeve, and the rotation of the driving wheel can drive the rotating drive block to rotate, thereby driving the vibrating rod body to rotate.

[0014] Since multiple pressure roller rods are located at the lower part of the vehicle body and are arranged at equal intervals, the flexible belt body is stretched on the corresponding support wheels and drive wheels, the outer side of the flexible belt body is flat, and the lower sides of the pressure roller rods located at the lower side of the vehicle body are all in contact with the corresponding side walls of the vehicle body, and the diameter of the pressure roller rods is small, when the chassis vehicle travels on the concrete mortar, the concrete mortar squeezes the flexible belt body upward, making the flexible belt body located at the lower side of the pressure roller rod relatively convex, so that the contact surface between the flexible belt body and the concrete is a concave and convex surface, thereby playing an anti-slip role, and the outer side of the flexible belt body is flat, and will not leave deep grooves on the concrete surface, thereby reducing the difficulty of leveling and reducing the workload of leveling.

[0015] In an optional embodiment, the middle part of the inner side of the flexible belt body is adapted to be equipped with a force transmission convex strip, and the width of the force transmission convex strip is smaller than the width of the flexible belt body; the driving wheel is provided with a tooth groove adapted to the force transmission convex strip, and the middle part of the side wall of the support wheel is provided with a ring groove for the force transmission convex strip to pass through; two rows of pressure roller rods are provided on both sides of the vehicle body, and the two rows of pressure roller rods are respectively arranged on both sides of the length direction of the corresponding force transmission convex strip, so as to drive the flexible belt body to circulate around the driving wheel and the support wheel through the cooperation between the driving wheel and the force transmission convex strip, thereby preventing the flexible belt body from slipping relative to the driving wheel.

[0016] In an optional embodiment, a mounting cavity for accommodating a battery is provided in the battery compartment; an air duct is vertically provided on the top of the battery compartment, the lower end of the air duct is connected to the mounting cavity, and an air inlet is provided on the bottom of the battery compartment; a heat-conducting metal plate is adapted to be provided in the mounting cavity, and the heat-conducting metal plate is located at the upper part of the mounting cavity; the middle part of the heat-conducting metal plate is covered with a heat-conducting silicone layer, and the heat-conducting silicone layer can transfer the heat of the battery to the heat-conducting metal plate, and air vents are provided on both sides of the heat-conducting metal plate, so that the hot air generated in the mounting cavity is discharged from the air duct, thereby drawing in ambient air through the air inlet, so as to utilize the chimney effect to cool the battery. Compared with the use of a cooling fan, the structure is simple, no additional power is consumed, and the endurance of the chassis vehicle is improved.

[0017] In an optional embodiment, the mechanical arm includes a supporting cross arm, a connecting rubber block and a vertical drive; the supporting cross arm includes a fixed arm, a connecting cross bar and an electric push rod, one end of the fixed cross arm is used to install the driving motor of the vibrator, and the other end is connected to the chassis through a vertical rod, one end of the connecting cross bar is fixedly connected to the end of the fixed arm connected to the chassis, and the other end is hinged to the lower side of the end of the connecting rubber block facing the fixed arm, one end of the electric push rod is fixedly connected to the end of the fixed arm connected to the chassis, and the other end is hinged to the upper side of the end of the connecting rubber block facing the fixed arm; a first connecting rod is embedded in the connecting rubber block A connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are spaced apart along the length direction of the supporting cross arm, a connecting bolt is provided on the outer side of the first connecting plate, the connecting bolt is connected to the vertical driver, a first connecting lug and a second connecting lug are vertically spaced apart on the outer side of the second connecting plate, the first connecting lug is connected to the electric push rod, and the second connecting lug is connected to the connecting cross bar; one side of the vertical driver is fixedly connected to the connecting rubber block, which is used to install the vibrating rod body and drive the vibrating rod body to move up and down; wherein, when the electric push rod contracts, it can drive the vertical driver to tilt in the direction away from the fixed arm.

[0018] As a result, the middle position of the entire robotic arm is connected to the chassis, so that the chassis is subjected to balanced force, avoiding a larger force on one side of the chassis and causing a larger sinking on the concrete surface. The vertical driver on which the vibrating rod is installed is connected to the support cross arm via a rubber block, which can absorb the vibration generated by the vibrating rod, thereby preventing the vibration of the vibrating rod from being transmitted to the drive motor and the chassis, ensuring the normal operation of the drive motor and the chassis. At the same time, the vertical driver can drive the vibrating rod to move up and down, thereby adjusting the insertion depth of the vibrating rod according to the thickness of the concrete to ensure the vibration effect. In addition, the inclination angle of the vibrating rod installed on the vertical driver can be adjusted, which can reduce the resistance of the vibrating rod when moving relative to the concrete, making it easier for the chassis to drive the vibrating rod forward, and also can adjust the range of the vibrating rod's vibration.

[0039] Example

[0040] Combine Figure 1 This embodiment provides a concrete vibrating device, including a vibrating mechanism 100, a chassis 200 and a mechanical arm 300. The vibrating mechanism 100 is mounted on the chassis 200 via the mechanical arm 300. The vibrating mechanism 100 includes a vibrating rod body 110, a vibrating disk and a vibrating cylinder 130. The vibrating rod body 110 is a hollow structure. A vibrating plate 120 is installed in the vibrating rod body 110. The upper end of the vibrating plate 120 is fixedly connected to the vibrating rod body 110, and the lower end is suspended from the lower end of the vibrating rod body 110. The length direction of the vibrating plate 120 is 1 / 4 of the vibrating plate 120. There are vibrating heads 121 on both sides of the vibrating cylinder 130, and the vibrating cylinder 130 is adapted to be equipped with a vibrating piston 131. The side of the vibrating piston 131 facing the vibrating plate 120 is the normal pressure side and is fixedly connected to a vibrating hammer 132, and the end of the vibrating cylinder 130 away from the vibrating plate 120 is connected to the alternating pressurized hydraulic source; the middle part of the mechanical arm 300 is connected to the chassis 200, and the hydraulic source and the vibrating rod body 110 are respectively arranged at both ends of the mechanical arm 300; wherein, under the drive of the hydraulic source, the vibrating hammer 132 can hammer the side wall of the vibrating plate 120.

[0041] Combine Figure 2 Specifically, the vibrating rod 110 is provided with a vent hole 111 at the upper end to ensure that the interior of the vibrating rod 110 is at normal pressure. The vibrating plate 120 is a stainless steel spring to ensure that the vibrating plate 120 has a sufficient service life. The vibrating cylinder 130 is usually connected to the hydraulic source through a pipe.

[0042] In this embodiment, the vibrating mechanism 100 further includes: a hydraulic cylinder 180, wherein a drive piston 181 is adapted to be housed within the hydraulic cylinder 180, a hydraulic pipe 160 being connected to the output end of the hydraulic cylinder 180; and a drive plate 190 connected to the drive piston 181 via a drive connecting rod 191. The drive connecting rod 191 is hingedly connected to the drive piston 181 at one end and hingedly connected to the body of the drive plate 190 at the other end, such that the drive plate 190, the drive piston 181, and the drive connecting rod 191 form a slider-crank mechanism. Rotation of the drive plate 190 drives the drive piston 181 to slide back and forth along the axis of the hydraulic cylinder 180, thereby alternately inputting and outputting hydraulic oil into and out of the vibrating cylinder 130. It should be understood that the drive plate 190 is driven to rotate by a vibrating motor 192. The drive plate 190 and the hydraulic cylinder 180 are typically mounted within a closed housing to form a hydraulic source.

[0043] It should be noted that the existing concrete vibrator is driven by a flexible shaft, has a low transmission rate and a large energy loss, is only suitable for fixed-frequency vibration, and is difficult to adjust according to the on-site concrete distribution and concrete compaction degree. In order to ensure the quality of the concrete structure, repeated vibration cycles are required, resulting in low vibration efficiency and affecting the construction period.

[0044] The concrete vibrating device provided in this embodiment has a vibrating plate 120 and a vibrating cylinder 130 installed in a hollow vibrating rod body 110. The upper end of the vibrating plate 120 is fixedly connected to the vibrating rod body 110, and the lower end is suspended from the lower end of the vibrating rod body 110. Vibrating heads 121 are provided on both sides of the length direction. The vibrating cylinder 130 is adapted to be equipped with a vibrating piston 131. The side of the vibrating piston 131 facing the vibrating plate 120 is the normal pressure side and is fixedly connected to a vibrating hammer 132. The cylinder 130 inputs an alternating pressurized hydraulic source to drive the vibrating hammer 132 to hammer the side wall of the vibration plate 120. At the same time, since the side of the vibrating piston 131 facing the vibration plate 120 is in a normal pressure state, when the hydraulic oil flows back, the negative pressure in the vibrating cylinder 130 can drive the vibrating piston 131 to reset, so that the vibrating hammer 132 periodically hammers the vibration plate 120, thereby driving the vibrating head 121 to impact the corresponding side wall of the vibrating rod body 110, and then driving the vibrating rod body 110 to vibrate.

[0045] Therefore, compared with the rotation of the eccentric wheel driven by the soft shaft, on the one hand, the transmission efficiency is high, it is not affected by the bending of the connecting pipe, the energy loss is small, and the transmission modulation rate is large. By changing the alternating frequency of the hydraulic source, the vibration frequency of the vibrating rod body 110 can be changed to adjust according to the on-site concrete distribution and the concrete compaction degree, thereby ensuring the quality of the concrete structure and high vibration efficiency, thereby shortening the construction period; on the other hand, when the alternating frequency of the hydraulic source is constant, the vibrating punch 121 vibrates the vibration plate 120 at a certain frequency, so that the frequency of the vibration plate 120 changes periodically from high to low within the set frequency range, thereby making the vibration frequency of the vibrating rod body 110 also change periodically from high to low, and then variable frequency vibration within a certain range can avoid the phenomenon of concrete exudation and sand and gravel stratification.

[0046] Continue to combine Figure 2 The vibration mechanism 100 also includes: a rotating drive block 140, which is a hollow structure, and the vibrating cylinder 130 is connected to the inner cavity of the rotating drive block 140; a support shaft 150, one end of which is sealed and inserted inside the rotating drive block 140, and the rotating drive block 140 can rotate around the support shaft 150; a hydraulic pipe 160, one end of which is connected to the inner cavity of the rotating drive block 140 through the support shaft 150, and is used to connect to the alternating pressurized hydraulic source; wherein, the upper end of the vibrating rod body 110 is coaxially and fixedly connected to the rotating drive block 140.

[0047] It can be understood that the upper end of the vibrating rod body 110 is coaxially fixedly connected to the rotating drive block 140, and one end of the support shaft 150 is sealed and inserted inside the drive. The driving component can drive the vibrating plate to rotate around the support shaft 150, thereby vibrating the concrete around the vibrating rod body 110, improving the vibration efficiency, and making the rotating drive block 140 rotate around the support shaft 150. The lower part of the support shaft 150 is always inside the rotating drive block 140, and the vibrating cylinder 130 is always in a state of communication with the inside of the rotating drive block 140, so that the vibrating cylinder 130 always remains in a state of communication with the hydraulic pipe 160, ensuring that the vibrating cylinder 130 can obtain hydraulic pressure.

[0048] Furthermore, the rotating drive block 140 is adapted to be equipped with a flexible sleeve 141 on the outside. The flexible sleeve 141 is fixedly connected to the rotating drive block 140, so that the driving connection between the rotating drive block 140 and the driving component is a connection with a certain flexibility, thereby reducing the phenomenon of the rotating drive block 140 slipping relative to the driving component.

[0049] Optionally, the rotary driving block 140 is made of polytetrafluoroethylene to utilize the self-lubricating property of polytetrafluoroethylene to reduce the friction of the rotation of the vibrating rod body 110 .

[0050] It should be understood that the vibration mechanism 100 also includes a driving wheel 170, which abuts against the outside of the flexible sleeve 141, and the rotation of the driving wheel 170 can drive the rotating drive block 140 to rotate, so as to actively drive the rotating drive block 140 through the friction between the driving wheel 170 and the flexible sleeve 141, thereby driving the vibrating rod body 110 to rotate. During the rotation of the rotating drive block 140, the side walls of the flexible sleeve 141 are alternately deformed, thereby preventing the concrete mortar from becoming compacted on the outside of the flexible sleeve 141.

[0051] The support shaft 150 is provided with a connection hole 151 in the middle thereof, and a pagoda joint 152 is adapted to fit within the connection hole 151. One end of the hydraulic tube 160 is sleeved onto the outside of the pagoda joint 152 to facilitate connection between the support shaft 150 and the hydraulic tube 160. Optionally, the hydraulic tube 160 is a flexible hose, which not only facilitates the laying of the hydraulic tube 160 but also prevents the vibration of the vibrating rod 110 from affecting the hydraulic tube 160.

[0052] Combine Figure 3 Specifically, in this embodiment, the chassis vehicle 200 includes a vehicle body 210, and a flexible belt body 220, a support wheel 211 and a drive wheel 170 are provided on both sides of the length direction of the vehicle body 210; a plurality of pressure roller rods 213 are equidistantly arranged on both sides of the lower part of the vehicle body 210 along its length direction, and each of the pressure roller rods 213 extends along the width direction of the flexible belt body 220; the outer side surface of the flexible belt body 220 is flat, and the flexible belt body 220 is stretched on the corresponding support wheel 211 and the drive wheel 170, and the lower sides of the pressure roller rods 213 located on the lower side of the vehicle body 210 all abut against the corresponding inner side wall of the flexible belt body 220.

[0053] Furthermore, the middle part of the inner side of the flexible belt body 220 is adapted to be equipped with a force transmission convex strip 221, and the width of the force transmission convex strip 221 is smaller than the width of the flexible belt body 220; the driving wheel 170 is provided with a tooth groove adapted to the force transmission convex strip 221, and the middle part of the side wall of the support wheel 211 is provided with an annular groove for the force transmission convex strip 221 to pass through, so that the flexible belt body 220 is driven to circulate around the driving wheel 170 and the support wheel 211 through the cooperation between the driving wheel 170 and the force transmission convex strip 221, thereby preventing the flexible belt body 220 from slipping relative to the driving wheel 170.

[0054] It can be understood that two rows of pressure roller rods 213 are provided on both sides of the vehicle body 210, and the two rows of pressure roller rods 213 are arranged on both sides of the length direction of the corresponding force transmission convex strips 221 to ensure that the part of the flexible bag body pressed into the concrete mortar has sufficient width.

[0055] Among them, the support wheel 211 and the driving wheel 170 arranged on the same side are respectively arranged at both ends of the length direction of the vehicle body 210, and the lower side of each pressure roller rod 213 is located below the lower side of the support wheel 211 and the driving wheel 170 arranged on the same side, so as to ensure that the flexible belt body 220 below the pressure roller rod 213 can bulge relatively outward.

[0056] Generally speaking, the distance between the support wheel 211 and the drive wheel 170 is adjustable to facilitate the deployment of the flexible belt 220 and adjust the tension of the flexible bag, thereby adjusting the depth to which the pressure roller 213 pushes the flexible belt 220 into the concrete mortar. The drive wheel 170 is a brushless motor wheel, and the drive wheel 170 provides driving power, thereby simplifying the structure of the chassis 200 and reducing the weight of the chassis 200.

[0057] Continue to combine Figure 3 The chassis vehicle 200 further includes a battery compartment 230 , which is located in the middle of the upper side of the vehicle body 210 to provide protection for the battery.

[0058] Combine Figure 4 Specifically, the battery compartment 230 is provided with an installation cavity 231 for accommodating a battery 232; an air duct 233 is vertically provided on the top of the battery compartment 230, and the lower end of the air duct 233 is connected to the installation cavity 231, and an air inlet 234 is provided at the bottom of the battery compartment 230, so that the hot air generated in the installation cavity 231 is discharged from the air duct 233, and the ambient air is drawn in through the air inlet 234 to utilize the chimney effect to cool the battery 232. Compared with the use of a cooling fan, the structure is simple and no additional power is consumed, thereby improving the endurance of the chassis vehicle 200.

[0059] Furthermore, a heat-conducting metal plate 235 is adapted in the installation cavity 231, and the heat-conducting metal plate 235 is located at the upper part of the installation cavity 231; the middle part of the heat-conducting metal plate 235 is covered with a heat-conducting silicone layer, and the heat-conducting silicone layer can transfer the heat of the battery 232 to the heat-conducting metal plate 235, and vents 111 are provided on both sides of the heat-conducting metal plate 235 to concentrate the heat generated by the battery 232 during operation through the heat-conducting silicone layer and the heat-conducting metal plate 235, thereby increasing the temperature of the gas at the upper end of the working cavity, enhancing the chimney effect, and quickly cooling the battery 232.

[0060] It should be understood that an electric turntable 236 is mounted on the top of the battery compartment 230 to facilitate mounting of the robotic arm 300 and to allow the vibrating arm to rotate as a whole, expanding its operating range. The electric turntable 236 typically consists of a servo motor drive shaft fitted with a drive gear, which in turn drives a ring gear, thereby rotating a flange fixedly connected to the ring gear. The frame supporting the vibrating rod is then fixedly connected to the flange.

[0061] That is to say, the chassis vehicle 200 provided in this embodiment is provided with a flexible belt body 220, a support wheel 211, a driving wheel 170 and a plurality of pressure roller rods 213 on both sides of the vehicle body 210 in the longitudinal direction. The plurality of pressure roller rods 213 are located at the lower part of the vehicle body 210 and are arranged at equal intervals. The flexible belt body 220 is stretched on the corresponding support wheel 211 and the driving wheel 170. The outer side surface of the flexible belt body 220 is flat, and the lower sides of the pressure roller rods 213 located at the lower side of the vehicle body 210 are all in contact with the vehicle body 210. 0 corresponding to the side wall, the diameter of the pressure roller rod 213 is small, so that when the chassis 200 travels on the concrete mortar, the concrete mortar presses the flexible belt body 220 upward, making the flexible belt body 220 located on the lower side of the pressure roller rod 213 relatively convex, so that the contact surface between the flexible belt body 220 and the concrete is a concave and convex surface, thereby playing a role in anti-slip, and the outer side of the flexible belt body 220 is flat, and will not leave deep grooves on the concrete surface, thereby reducing the difficulty of smoothing and reducing the workload of smoothing.

[0062] Combine Figure 5 In this embodiment, the robotic arm 300 includes: a supporting cross arm 310, the middle portion of which is connected to the chassis 200, and one end of which is used to mount the vibrating motor of the vibrator; a connecting rubber block 320, one side of which is fixedly connected to the other end of the supporting cross arm 310; and a vertical driver 330, one side of which is fixedly connected to the connecting rubber block 320, and is used to mount the vibrating rod body 110 and drive the vibrating rod body 110 to move up and down.

[0063] Specifically, the support cross arm 310 includes: a fixed arm 311, one end of which is used to install the driving motor of the vibrator (that is, the vibrating motor is installed at one end of the fixed arm 311), and the other end is used to connect to the chassis 200; a connecting cross bar 312, one end of which is fixedly connected to the end of the fixed arm 311 connected to the chassis 200, and the other end is hinged to the lower side of the end of the connecting rubber block 320 facing the fixed arm 311; an electric push rod 313, one end of which is fixedly connected to the end of the fixed arm 311 connected to the chassis 200. The other end is hinged to the upper side of one end of the connecting rubber block 320 facing the fixed arm 311; wherein, when the electric push rod 313 contracts, it can drive the vertical driver 330 to tilt in the direction away from the fixed arm 311, that is, the inclination angle of the vibrating rod body 110 installed on the vertical driver 330 can be adjusted to reduce the resistance of the vibrating rod body 110 when it moves relative to the concrete, making it easier for the chassis 200 to drive the vibrating rod body 110 forward, and at the same time, the vibration range of the vibrating rod body 110 can also be adjusted.

[0064] The connecting cross bar 312 is made of aluminum alloy, so as to reduce the weight of the connecting cross bar 312 while ensuring that the connecting cross bar 312 has sufficient mechanical strength.

[0065] Accordingly, the fixed arm 311 is a hollow aluminum alloy shell structure, which ensures that the fixed arm 311 has sufficient mechanical strength while reducing its own weight, and also facilitates the layout of the driving connecting parts related to the vibrating rod body 110.

[0066] On this basis, the robotic arm 300 provided in this embodiment also includes a vertical pole 340, the upper end of the vertical pole 340 is fixedly connected to the lower side of one end of the fixed arm 311, and the lower end of the vertical pole 340 is used to connect to the chassis 200, so that the supporting cross arm 310 can be installed on the chassis 200 through the vertical pole 340.

[0067] Likewise, the vertical pole 340 is a hollow aluminum alloy pole structure, so as to reduce its own weight while ensuring that the vertical pole 340 has sufficient mechanical strength.

[0068] Generally speaking, the upper end of the vertical pole 340 is welded to the fixed arm 311, and the lower end of the vertical pole 340 is provided with a (welded) connecting flange 341, so that the entire robot arm 300 can be detachably connected to the chassis vehicle 200 to achieve a modular design.

[0069] Combine Figure 6In this embodiment, a first connecting plate 321 and a second connecting plate 322 are embedded in the connecting rubber block 320, and the first connecting plate 321 and the second connecting plate 322 are spaced apart along the length direction of the support cross arm 310; a connecting bolt is provided on the outside of the first connecting plate 321, and the connecting bolt is used to connect the vertical driver 330; a first connecting lug and a second connecting lug are vertically spaced apart on the outside of the second connecting plate 322, and the first connecting lug is connected to the electric push rod 313, and the second connecting lug is connected to the connecting cross bar 312, so as to facilitate the connection between the vertical driver 330 and the support cross arm 310.

[0070] The connecting rubber block 320 is made of EPDM rubber to ensure that the connecting rubber block 320 has sufficient weather resistance and corrosion resistance. The first connecting plate 321 and the second connecting plate 322 are made of aluminum alloy to reduce the weight of the connecting rubber block 320.

[0071] Optionally, the vertical driver 330 is a slide hydraulic cylinder to ensure that the vibrating rod body 110 can be reliably adjusted.

[0072] It should be noted that the robotic arm 300 provided in this embodiment has a supporting cross arm 310 whose middle part is connected to the chassis 200 through a vertical pole 340, a driving motor of the vibrator is installed at one end, and the other end is fixedly connected to the vertical driver 330 through a connecting rubber block 320. The vertical driver 330 is used to install the vibrating rod body 110 and drive the vibrating rod body 110 to move up and down; that is, the middle position of the entire robotic arm 300 is connected to the chassis 200, so that the chassis 200 is subjected to balanced force, avoiding a large sinking on the concrete surface due to a greater force on one side of the chassis 200.

[0073] Furthermore, the vertical actuator 330, on which the vibrating rod 110 is mounted, is connected to the support cross arm 310 via a connecting rubber block 320. This absorbs vibrations generated by the vibrating rod 110, thereby preventing the vibrations from the vibrating rod 110 from being transmitted to the drive motor and chassis 200, thereby ensuring the normal operation of the drive motor and chassis 200. Furthermore, the vertical actuator 330 can move the vibrating rod 110 up and down, thereby adjusting the insertion depth of the vibrating rod 110 according to the thickness of the concrete to ensure effective vibration.

[0074] In summary, the vibration mechanism 100 of this embodiment is installed on the chassis 200 through the mechanical arm 300, and the vibration mechanism 100 includes a vibration rod body 110, a vibration plate and a vibration cylinder 130, so as to drive the vibration hammer 132 to hammer the side wall of the vibration plate 120 by inputting an alternating pressurized hydraulic source into the vibration cylinder 130. At the same time, since the side of the vibration piston 131 facing the vibration plate 120 is in a normal pressure side state, when the hydraulic oil flows back, the negative pressure in the vibration cylinder 130 can drive the vibration piston 131 to reset, so that the vibration hammer 132 periodically hammers the vibration plate 120, thereby driving the vibration head 121 to impact the corresponding side wall of the vibration rod body 110, so as to drive the vibration rod body 110 to vibrate, and then the vibration mechanism 100 is driven to move on the concrete through the chassis 200, so that the vibration rod body can automatically drive the vibration rod body to efficiently vibrate the concrete on the unsolidified concrete dam body, thereby meeting the construction requirements of the hydropower project dam pouring.
