TECHNICAL FIELD

[0001] The present application relates to the technical field of building materials, and in particular to a full-automatic pile head polishing machine. BACKGROUND

[0002] In the current pipe pile industry, the pile head formed by oxidation of rust layer or bonded concrete needs to be polished, which is traditionally mainly dependent on manual operation. Manual polishing of the pile head usually involves the use of handheld power tools or fixed abrasive cut-off machines and the like, and the worker needs to polish the pipe pile ends and pile sleeve according to specific operation requirements to remove the surface unevenness, burrs, rust and excess concrete material, so as to ensure the flatness and brightness of the pile head. This manual operation method is largely dependent on the experience and skill of the worker, so there may be a large difference in polishing effect between different workers.

[0003] Moreover, there are many safety hazards in the manual polishing process. For example, long-term exposure to high-decibel noise environment may cause hearing damage; contact with dust may cause respiratory diseases; and improper operation may easily cause cuts, burns and other work accidents. In addition, due to the poor working environment and high labor intensity, workers who have been engaged in such work for a long time may also face the risk of occupational diseases.

[0029] The following will clearly and completely describe the concept, specific structure, and resulting technical effects of this application in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this application. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this application can be combined interactively without contradicting each other.

[0030] like Figures 1-5 The fully automatic pile head grinding machine shown includes a moving component 1 and a grinding component 2; the grinding component 2 includes a rotating disk 21 and a plurality of brush heads 22 disposed on the rotating disk 21 and facing the pipe pile, the brush heads 22 are provided with brush strips 23, and the rotating disk 21 is provided with a plurality of through holes 24.

[0031] The moving component 1 can drive the grinding component 2 to move on the ground track 3 on which the pipe piles are placed.

[0032] Therefore, in the above technical solution, the rotation and friction of the brush strip can remove impurities and unevenness from the surface and end face of the pile head sleeve of the pipe pile; the perforation setting reduces the weight of the rotating disk and lowers the center of gravity of the fully automatic pile head grinding machine, while also helping to dissipate heat and reduce vibration.

[0033] In one or more embodiments, the ratio of the sum of the areas of the plurality of perforations 24 to the area of ​​the rotating disk 21 is greater than 1:5.

[0034] Specifically, when the rotating disk rotates under the drive of the motor, the perforations rotate accordingly, promoting air circulation and heat dissipation. There can be four perforations, evenly and symmetrically distributed on the rotating disk, formed through specific processes (such as drilling, stamping, etc.).

[0035] The ratio of the sum of the areas of the perforations to the area of the rotating disc is greater than 1:5. This arrangement increases the perforation area to improve the heat dissipation performance of the device and reduce the weight, thereby reducing energy consumption and improving the efficiency of the operation of the device.

[0036] In one or more embodiments, as shown, the brush head 22 is shaped in an L shape, and the brush head 22 is provided with brush strips 23. Figure 3

[0037] Specifically, the brush strips are fixed on the brush head, which can be welded, bolted, or buckled, and directly contact the surface and end face of the pile head of the pipe pile. The brush strips rotate with the brush head to polish the pipe pile.

[0038] Specifically, the design of the L-shaped brush head is based on geometric principles to maximize the contact area and adaptability, while also dispersing the wear on the brush strips and reducing the problem of concentrated wear points, ensuring stability and durability during high-speed rotation.

[0039] In one or more embodiments, the brush strips 23 are made of a workshop-replaced steel wire rope.

[0040] Specifically, the workshop-replaced steel wire rope is a stainless steel wire rope, which has the characteristics of strong rust resistance, corrosion resistance, wear resistance, and high strength, and can withstand long-term polishing operations, reducing the frequency of replacement and reducing maintenance costs.

[0041] Specifically, the brush strips can directly contact the surface and end face of the pile head sleeve, facilitating polishing.

[0042] In one or more embodiments, the brush head 22 is detachably arranged on the rotating disc 21.

[0043] Specifically, the detachable design uses quick-release mechanisms such as quick-change couplings, buckles, and bolts to achieve quick replacement of the brush head. For example, the brush head is fixed on the rotating disc by buckles, bolts, etc.

[0044] Therefore, through the detachable brush head design, the brush head can be quickly replaced when it is worn or damaged, reducing downtime and improving production efficiency. At the same time, different sizes and dimensions of brush heads can be replaced according to actual conditions to adapt to pipe piles of different hole diameters.

[0045] In one or more embodiments, the mobile assembly 1 includes a first motor 11 and a wheel set 12 cooperating with the ground rail 3.

[0046] ​Specifically, the first motor serves as a power source and drives the wheel set to rotate through a transmission device (such as a speed reducer, a shaft coupling, etc.). The wheel set cooperates with the ground track to form a stable moving mechanism. By controlling the rotating speed and direction of the first motor, the moving speed and direction of the polishing machine can be accurately controlled. Meanwhile, in combination with sensors and a PLC control system, the polishing machine can be automatically controlled and positioned.

[0047] In one or more embodiments, as shown in Figure 4 the rotating assembly 4 further includes a second motor 41 that drives the rotating disc 21 to rotate.

[0048] Specifically, the rotating disc is driven to rotate by the second motor, so that the brush head polishes the pipe pile, improving the polishing efficiency and quality.

[0049] In one or more embodiments, the moving assembly 1, the polishing assembly 2, and the rotating assembly 4 are arranged on the support 5.

[0050] Specifically, the support provides mechanical support for the entire device and ensures the stability of the device through reasonable structural design.

[0051] In one or more embodiments, the protective cover 6 is arranged on the support 5.

[0052] Specifically, the protective cover protects the operator from flying debris and reduces external interference to ensure the safety of the polishing process.

[0053] In one or more embodiments, as shown in Figure 5 the ground track 3 is provided with a pre-embedded plate 7 for placing the pipe pile.

[0054] Specifically, the pre-embedded plate is used to fix the pipe pile, ensuring the accuracy and stability of the position of the pipe pile during polishing.

[0055] More specifically, the full-automatic pile head polishing machine described in the present application connects the moving assembly and the polishing assembly through a support or a frame, arranges the polishing assembly in front of the moving assembly, so that the moving assembly can carry the polishing assembly to move along the ground track, detachably installs the brush head on the rotating disc for convenient replacement and maintenance; the rotating disc is connected with the second motor through a shaft, and the second motor provides rotating power; the first motor (moving assembly) is connected with the wheel set through a transmission device (such as a chain or a belt) to provide power for movement.

[0056] The moving assembly is located above the ground track and is responsible for the movement of the entire device on the ground track. The polishing assembly is installed above the moving assembly and moves with it, and starts the polishing action at the designated position. The rotating disc is at the core of the polishing assembly, and the brush head is arranged around it, facing the pipe pile to be polished. The embedded plate is fixed beside the ground track and serves as the positioning point of the pipe pile.

[0057] During operation, the moving assembly (wheel set) moves linearly along the ground track to bring the polishing assembly in front of the pipe pile to be polished. The rotating disc rotates under the drive of the second motor, driving the brush head to polish the surface of the pipe pile. The brush strip contacts the surface of the pipe pile as the rotating disc rotates, performing the actual polishing work. The taper of the tread of the wheels of the wheel set is designed to help maintain accurate alignment with the center position of the pile head when the polisher is moving forward.

[0058] More specifically, the fully automatic pile head polisher described in the present application can achieve automatic control and positioning of the polisher by combining sensors and a PLC control system. The sensor and PLC control system can use existing technology to achieve automatic control and positioning functions, or can be implemented according to the following content:

[0059] 1. PLC control system composition

[0060] The PLC control system mainly consists of a central processing unit (CPU), input / output modules (I / O modules), memory, power supply, and programmer. Among them, the CPU is responsible for executing program instructions, the I / O module is used to receive external signals and output control signals, the memory stores programs and data, the power supply provides the power required by the system, and the programmer is used to write and modify the control program.

[0061] 2. PLC control flow

[0062] ① Initialization and self-checking

[0063] Before starting the polisher, the PLC first performs initialization operations, including memory zeroing, initialization of variables, checking the status of each I / O module, etc.

[0064] Subsequently, the PLC performs self-checking to confirm that each hardware module is working properly and there is no fault alarm.

[0065] ② Input signal acquisition

[0066] The PLC acquires external input signals through the I / O module, including the arrival signal of the pipe pile (such as the pile head position detected by the photoelectric sensor), the polishing time setting signal (such as the polishing time input by the touch screen), and the emergency stop signal.

[0067] ③ Logic operation and judgment

[0068] According to the collected input signals, PLC performs logical operations and judgments to determine the next action of the grinder.

[0069] For example, when the pipe pile in place signal is detected, the PLC determines whether the grinder is ready. If it is ready, it enters the grinding program; if it is not ready (such as the grinding assembly is not reset, the protective cover is not closed, etc.), it sends an alarm signal and stops running.

[0070] ④ Output control signal

[0071] According to the results of logical operations, PLC outputs control signals through I / O modules to command the actions of each actuator.

[0072] For example, when the PLC decides to start grinding, it will output signals to start the first motor (to drive the moving assembly), the second motor (to drive the rotating assembly), etc.

[0073] ⑤ Grinding process control

[0074] During the grinding process, PLC continuously monitors parameters such as grinding time, position of the grinding assembly, and running state of the motor.

[0075] When the set grinding time is reached, PLC outputs signals to stop the running of the grinding assembly and starts the moving assembly to return the grinding assembly to its original position.

[0076] At the same time, PLC is also responsible for monitoring the running state of each actuator. If an abnormality occurs (such as motor overload, temperature sensor alarm, etc.), it will immediately stop running and send an alarm signal.

[0077] ⑥ Cycle and reset

[0078] After completing a grinding task, PLC controls the grinder to return to the initial position, preparing for the next cycle.

[0079] During continuous grinding, PLC will automatically start the next grinding task according to the set time interval or external signals (such as a new pipe pile in place signal).

[0080] When the grinder needs to be stopped, a stop signal can be sent through the touch screen or emergency stop button. PLC receives the signal and performs the corresponding stop operation (the process is: a main contactor is designed in the PLC control system to control the power supply of each mechanism of the device. When the emergency stop button sends a signal, the main contactor disconnects the power supply of each mechanism of the device, achieving emergency stop operation).

[0081] PLC control system is usually installed in the control box of the grinder. PLC is connected with I / O modules and sensors through cables; sensors are set on the support and on the ground track to collect external signals and transmit them to PLC.

[0082] Therefore, the whole operation process of the full-automatic pile head grinding machine is as follows:

[0083] The grinding machine is started and the PLC control system is initialized; the crane operator hoists the pipe pile to the pile storage platform and presses the start button. After the PLC control system acquires the pipe pile positioning signal, the grinding program is started; the moving assembly moves the grinding assembly along the ground track to the pipe head of the pipe pile and positions it; the rotating assembly is started and drives the grinding assembly to grind the pipe pile.

[0084] After the grinding is completed, the PLC control system stops the rotating assembly; the moving assembly moves the grinding machine away from the pipe pile, the crane operator operates the crane to hoist the ground pipe pile and place a new pipe pile for the next grinding.

[0085] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the described embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
