Description

Technical Field

[0001] The present application relates to the technical field of concrete vibrating equipment, and in particular to a vibrating machine for the construction of building concrete main structures. Background Art

[0002] As the core equipment for the intelligent transformation of buildings, the market prospects of vibrating robots are showing explosive growth driven by policy promotion, technological iteration and cost optimization.

[0003] To improve vibration efficiency, a vibrating robot is typically equipped with multiple vibrators arranged side by side. During vibration, the vibrators are simultaneously inserted into the concrete and moved in a matrix pattern. However, concrete is often densely packed with rebar, making it difficult to ensure that each vibrator avoids the rebar during insertion, impacting the vibration effect and reducing the rods' service life.

[0004] Secondly, intelligent robots generally control the insertion position of the vibrating rod through remote control or visual perception to avoid steel bars. The adjustment process is relatively time-consuming, which reduces the vibration efficiency. Summary of the Invention

[0005] The present application proposes a vibrating machine for the construction of building concrete main structures, which uses a metal detector to detect the position of steel bars and independently adjusts the position of each vibrating rod to ensure that each vibrating rod can avoid the steel bars and ensure the quality of vibration.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a vibrator for the construction of building concrete main structure, including a connecting frame, an adjusting arm, a metal detector and an adjusting assembly. The connecting frame is assembled on the mechanical arm of the vibrating robot, the adjusting arm is hinged to the connecting frame, and the adjusting arm is connected to a vibrating rod. The vibrating rod can pass through the metal detector, and the metal detector can detect the metal directly below the vibrating rod. The metal detector rotates synchronously with the adjusting arm. When a metal detector detects the presence of metal directly below the vibrating rod, the adjusting assembly drives the corresponding adjusting arm to rotate until the vibrating rod can no longer detect the metal. When all metal detectors can no longer detect the metal, the vibrating rod continues to be inserted downward.

[0007] Furthermore, it also includes a synchronization rod, the side wall of the synchronization rod is provided with an axial limit block, the synchronization rod passes through the rotating shaft of the adjustment arm and is movably connected to the rotating shaft, the rotating shaft is fixedly connected to the adjustment arm and movably connected to the connecting frame, the rotation of the adjustment arm drives the synchronization rod to rotate and can slide up and down along the side wall of the synchronization rod, the metal detector is fixedly connected to the synchronization rod, and the upper end of the synchronization rod is provided with a protrusion.

[0008] Furthermore, the bottom of the synchronization rod is connected to a suspended seat. The suspended seat has an arc-shaped slot corresponding to the position of the vibrator. The center of the arc-shaped slot is perpendicular to the center of the adjustment arm's rotating shaft. The width of the arc-shaped slot is 1.5-2 times the diameter of the vibrator. The suspended seat is suspended in the position corresponding to the arc-shaped slot of the vibrator. This prevents concrete from solidifying on the inner wall of the arc-shaped slot. The bottom of the synchronization rod is connected to the suspended seat via a bearing, which supports the synchronization rod and prevents it from being inserted into the concrete.

[0009] Furthermore, the adjustment assembly includes a worm gear and a worm sleeve. The worm gear is fixedly connected to the adjustment arm, and the worm sleeve is connected to a driver. The worm sleeve drives the adjustment arm to rotate via the worm gear. The worm sleeve and worm gear have a self-locking function, which can prevent the adjustment arm from rotating due to vibration of the vibrating rod.

[0010] Furthermore, the adjustment assembly also includes a drive shaft, which passes through each worm sleeve, and the driver is connected to the drive shaft. A clutch assembly is provided between the drive shaft and the worm sleeve, and the clutch assembly can connect or disconnect the transmission between the drive shaft and the worm sleeve.

[0011] Furthermore, the clutch assembly includes an electromagnetic seat fixedly mounted on the connecting frame and a floating block floating radially along the drive shaft. The floating block can be attracted and moved by the electromagnetic seat. The floating block is connected to an elastic pull rope. The electromagnetic seat corresponds to the worm sleeve one-to-one. The elastic pull rope pulls the floating block back. At this time, the worm sleeve can rotate freely relative to the drive shaft. The worm sleeve is provided with a transmission groove corresponding to the floating block. When the floating block is sucked out, the drive shaft can drive the worm sleeve to rotate.

[0012] Furthermore, the adjustment assembly also includes a mounting sleeve, the elastic pull rope and the floating block are installed in the mounting sleeve, and the drive shaft and the mounting sleeve are threadedly connected.

[0013] Furthermore, a flared section is provided on the side of the transmission groove close to the drive shaft, and a slope is provided on the circumference of the flared section. A spring is provided between the floating block and the drive shaft. The elasticity of the spring causes the outer side of the floating block to extend into the flared section but not beyond the flared section. A torsion spring is provided on the rotating shaft of the adjusting arm, and the torsion spring keeps the adjusting arm in an initial position.

[0014] The beneficial effects of the present invention are as follows:

[0015] The present application provides a vibrator for the construction of a building concrete main structure, which uses a metal detector to detect the position of steel bars and independently adjusts the position of each vibrating rod to ensure that each vibrating rod can avoid the steel bars and ensure the quality of vibration.

[0016] When adjusting the position of the vibrating rod, the vibrating rod moves along an arc. Since the steel bars are straight, it will inevitably avoid the steel bars. Therefore, when the robot moves, the position of each movement can be kept consistent without the need for additional adjustment, thereby improving the efficiency of each movement of the rod during vibration and increasing the vibration efficiency.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 are within the scope of protection of the present invention.

[0025] For example 1, please refer to Figure 1-Figure 2, a vibrating machine for the construction of a concrete main structure of a building, including a connecting frame 2, the connecting frame 2 is assembled on the mechanical arm 1 of the vibrating robot, the connecting frame 2 is hinged with an adjusting arm 3, the adjusting arm 3 is connected to a vibrating rod 4, the top of the vibrating rod 4 is provided with a connecting head, the connecting head is soft and can be bent arbitrarily, which can isolate the vibration of the vibrating rod 4 and prevent the vibration from being transmitted to the adjusting arm 3. In this embodiment, the vibrating rod 4 is driven by hydraulics, and the top of the vibrating rod 4 is connected with an oil pipe 9. Each oil pipe 9 is connected to the same main pipe, and the main pipe is connected to the hydraulic system. The adjusting arm 3 is connected to a metal detector 6 through a synchronization rod 5. The projection of the adjusting arm 3 is on the metal detector 6, and the two rotate synchronously. The metal detector 6 is a single-sided coil design, which can detect the metal directly below the vibrating rod 4. The adjusting arm 3 is connected to an adjustment component 8. When a certain metal When the metal detector 6 detects that there is metal directly below the vibrating rod 4, the adjustment assembly 8 drives the corresponding adjustment arm 3 to rotate until the vibrating rod 4 can no longer detect the metal. The adjustment arm 3 is movably connected to the synchronization rod 5, and the adjustment arm 3 can move axially relative to the synchronization rod 5. The side wall of the synchronization rod 5 is provided with an axial limit block. The connecting frame 2 and the adjustment arm 3 can slide up and down along the side wall of the synchronization rod 5. The metal detector 6 is fixedly connected to the synchronization rod 5, and the rotation of the adjustment arm 3 drives the synchronization rod 5 to rotate, and the synchronization rod 5 drives the metal detector 6 to rotate. The upper end of the synchronization rod 5 is provided with a protrusion to prevent the end of the synchronization rod 5 from passing through the connecting frame 2. The connecting frame 2 is movably connected to the synchronization rod 5 through a rotating ring. When each metal detector 6 can no longer detect metal, the robotic arm 1 drives the connecting frame 2 to move downward as a whole, so that the vibrating rod 4 is inserted into the concrete.

[0026] The bottom of the synchronization rod 5 is connected to a suspended seat 7, and the suspended seat 7 is provided with an arc groove corresponding to the position of the vibrating rod 4. The center of the arc groove is vertically connected to the center line of the rotating shaft of the adjustment arm 3. The width of the arc groove is 1.5-2 times the diameter of the vibrating rod 4, which does not interfere with the downward movement of the vibrating rod 4. The suspended seat 7 is suspended at the position corresponding to the arc groove of the vibrating rod 4 to prevent concrete from condensing on the inner wall of the arc groove. The bottom of the synchronization rod 5 is connected to the suspended seat 7 through a bearing. The suspended seat 7 supports the synchronization rod 5 to prevent the synchronization rod 5 from being inserted into the concrete.

[0027] See also Figure 3-Figure 4 The adjustment assembly 8 includes a worm gear 81 and a worm sleeve 83. A mounting column is provided on the adjustment arm 3. The worm gear 81 is sleeved on the mounting column. A flat key is provided between the two. The rotation of the worm gear 81 drives the adjustment arm 3 to rotate. A through hole is provided on the rotating shaft between the connecting frame 2 and the adjustment arm 3, which is adapted to the cross-section of the synchronization rod 5. The synchronization rod 5 passes through the rotating shaft, and the rotating shaft is fixedly connected to the mounting column to form a whole. The worm sleeve 83 is connected to a driver, which can be an electric motor or a hydraulic motor. The worm sleeve 83 drives the adjustment arm 3 to rotate through the worm gear 81. The cooperation between the worm sleeve 83 and the worm gear 81 has a self-locking ability, which can prevent the adjustment arm 3 from rotating due to the vibration of the vibrating rod 4.

[0028] The adjustment assembly 8 also includes a drive shaft 82, which passes through each worm sleeve 83. The driver is connected to the drive shaft 82. A clutch assembly 84 is provided between the drive shaft 82 and the worm sleeve 83. The clutch assembly 84 can connect or disconnect the transmission between the drive shaft 82 and the worm sleeve 83. When a metal detector 6 detects metal, the corresponding clutch assembly 84 connects the drive shaft 82 and the worm sleeve 83. When the metal detector 6 cannot detect metal, the corresponding clutch assembly 84 disconnects the transmission between the drive shaft 82 and the worm sleeve 83.

[0029] See also Figure 4 and Figure 5 The clutch assembly 84 includes an electromagnetic seat 841 fixedly mounted on the connecting frame 2 and a floating block 844 floating radially along the drive shaft 82. The floating block 844 can be attracted and moved by the electromagnetic seat 841. The floating block 844 is connected to an elastic pull rope 845. The electromagnetic seat 841 corresponds to the worm sleeve 83 one by one. The elastic pull rope 845 pulls the floating block 844 back. At this time, the worm sleeve 83 can rotate freely relative to the drive shaft 82. The worm sleeve 83 is provided with a transmission groove 842 corresponding to the floating block 844. The transmission groove 842 runs through the worm sleeve 83 to ensure that the magnetic force can drive the floating block 844 to move. The transmission slot 842 is movable, and a dustproof belt is wrapped around the corresponding position to prevent dust from entering. When the corresponding metal detector 6 detects metal, the electromagnetic base 841 is energized to generate a magnetic field to suck out the floating block 844. The drive shaft 82 can drive the worm sleeve 83 to rotate. In this embodiment, there are multiple groups of floating blocks 844 and transmission slots 842. The magnetic force of the electromagnetic base 841 can attract two groups of floating blocks 844 at the same time. For example, the angle between the two groups of floating blocks 844 is 120 degrees, and the magnetic range of the electromagnetic base 841 is greater than 120 degrees. In other embodiments, the electromagnetic base 841 can also be a complete circle.

[0030] The adjustment assembly 8 also includes a mounting sleeve 843 , in which the elastic pull rope 845 and the floating block 844 are installed. A threaded mounting hole corresponding to the mounting sleeve 843 is provided on the drive shaft 82 , and the mounting sleeve 843 is screwed into the worm sleeve 83 as a whole.

[0031] The transmission groove 842 is provided with a flared section on the side close to the drive shaft 82, and the flared section is provided with an inclined surface on the circumference. A spring 846 is provided between the floating block 844 and the drive shaft 82. The elasticity of the spring 846 makes the outer side of the floating block 844 extend into the flared section, but will not exceed the flared section. After the vibration is completed, the drive shaft 82 is reversed to reset the worm sleeve 83. When the worm sleeve 83 is reset to its position, the pressure between the floating block 844 and the flared section causes the floating block 844 to overcome the elastic force of the spring 846 and retract, thereby unloading the force, ensuring that each worm sleeve 83 and the adjustment arm 3 can be reset. A torsion spring is provided on the rotating shaft of the adjustment arm 3, which keeps the adjustment arm 3 in its initial position. When the drive shaft 82 drives the worm sleeve 83 to rotate, it needs to overcome the elastic force of the torsion spring, but the elastic force of the spring 846 and the friction between the drive shaft 82 and the worm sleeve 83 are insufficient to overcome the elastic force of the torsion spring, and the angle of the adjustment arm 3 is rotated too much.

[0032] The robot places the connecting frame 2 and the suspended seat 7 in the vibrating position through the mechanical arm 1. If a metal detector 6 detects the presence of metal below, the adjustment component 8 drives the corresponding adjustment arm 3 to rotate, and adjusts the position of the adjustment arm 3 and the metal detector 6. Since the steel bar is a straight line and the vibrating rod 4 moves along a circular path, the vibrating rod 4 will inevitably avoid the steel bar when it rotates a certain angle. After the vibrating rod 4 avoids the steel bar and the metal detector 6 can no longer detect the metal, the mechanical arm 1 controls the connecting frame 2 to descend, driving the vibrating rod 4 to be inserted into the concrete.

[0033] When the adjustment assembly 8 drives the adjustment arm 3 to rotate, the driver drives the drive shaft 82 to rotate. When a metal detector 6 detects metal, the corresponding electromagnetic seat 841 is energized, sucking out the floating block 844 within its range of action. The floating block 844 engages the transmission slot 842, driving the worm sleeve 83 to rotate. The worm sleeve 83 drives the adjustment arm 3 to rotate through the worm gear 81. When the metal detector 6 no longer detects metal, the electromagnetic seat 841 is de-energized, and the floating block 844 retracts under the elastic force of the elastic pull rope 845. At this time, the elastic force of the spring 846 is insufficient to overcome the torsion spring force on the adjustment arm 3. The rotation of the drive shaft 82 no longer drives the worm sleeve 83 to rotate. At the same time, due to the self-locking function of the worm sleeve 83 and the worm gear 81, the torsion spring force on the adjustment arm 3 also does not drive the adjustment arm 3 to rotate. After the vibration is completed, the drive shaft 82 is reversed, and the drive shaft 82 drives the worm sleeve 83 to rotate. When the adjustment arm 3 rotates to the initial position, the floating block 844 retracts under the pressure of the flaring section without affecting the reset of the other adjustment arms 3.
