Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of floor grinding equipment, and specifically relates to a multi -head floor grinding machine. BACKGROUND

[0002] The floor grinding machine is mainly used for grinding treatment of the ground, and it can effectively grind terrazzo, concrete surface layer, epoxy mortar layer and old epoxy ground. The floor grinding machine mainly comprises a moving mechanism and a grinding mechanism. The working surface of the grinding mechanism directly contacts the ground and grinds it, and the moving mechanism pushes the grinding mechanism to grind the ground of the whole site.

[0003] The existing floor grinding machine is mostly single -head type, and the processing efficiency is slow. The moving mechanism and the grinding disc mechanism share the same power source, so that the walking and grinding power cannot be separated, the manufacturing cost is high, the transportation and transfer are not convenient, and the comprehensive utilization rate is low. Therefore, in order to solve the above technical problems, the multi -head floor grinding machine is born, and the power of the moving mechanism and the grinding disc mechanism is independent of each other and does not interfere with each other. At this time, the multi -head floor grinding machine is widely used in various grinding scenes due to its excellent performance.

[0004] In patent application CN116423317A, a multi -head floor grinding machine is disclosed. The forklift is used as the walking power, and the grinding power of the grinding disc mechanism adopts a split type mounting structure, so that the forklift can be independently used, such as loading and unloading gear box and other grinding equipment or materials. At the same time, the working surface of the grinding disc mechanism can be reasonably exposed under the lifting function of the forklift, so as to facilitate the maintenance work of the staff. In the process of using the above-mentioned floor grinding machine, each grinding mechanism is installed on the same rack, and the working surface is located in the same plane, and the lifting of the rack is controlled by the forklift. Therefore, when one or more grinding mechanisms are not needed in the current grinding work, it is necessary to manually disassemble them. Similarly, when multiple grinding mechanisms are needed, it is necessary to manually load them on the rack. The whole disassembly and assembly process is relatively complicated, which greatly reduces the work efficiency. UTILITY MODEL CONTENTS

[0005] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a multi -head floor grinding machine. The grinding mechanism in the utility model can independently operate, and can be put into or withdrawn from the current grinding work according to the need without disassembly and assembly, which is convenient to operate and greatly improves the work efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A multi-head floor grinding machine comprises a carrier vehicle, a plurality of grinding units are installed on the carrier vehicle and can operate independently of each other, each grinding unit comprises a grinding mechanism and a lifting mechanism connecting the carrier vehicle and the grinding mechanism, and the lifting mechanism can make the working surface of the grinding mechanism away from or close to the surface to be ground.

[0008] As a further scheme of the utility model: along the advancing direction of the carrier vehicle, the grinding paths of the working surfaces of the two grinding mechanisms adjacent to each other partially overlap.

[0009] As a further scheme of the utility model: along the advancing direction of the carrier vehicle, the edges of the grinding paths of the two working surfaces adjacent to each other overlap each other.

[0010] As a further scheme of the utility model: the lifting mechanism comprises a pry bar hinged to the carrier vehicle, the base of the grinding mechanism is hinged to the prying end of the pry bar, a driving member is installed on the driving end of the pry bar, and the driving member can drive the prying end to swing up and down to complete the lifting action.

[0011] As a further scheme of the utility model: the working surface of the grinding mechanism hinged to the prying end is vertically downward under the action of gravity.

[0012] As a further scheme of the utility model: the driving member is a telescopic rod, and the two ends of the telescopic rod are hinged to the carrier vehicle and the driving end of the pry bar, respectively.

[0013] As a further scheme of the utility model: the pry bar comprises two L-shaped plates, the middle parts of the two L-shaped plates are fixed to each other through a connecting rod, the base of the grinding mechanism is hinged to the front ends of the two L-shaped plates, and the telescopic end of the telescopic rod is hinged to the tail ends of the two L-shaped plates.

[0016] As a further scheme of the utility model: there are three groups of grinding units, and they are distributed in a triangular shape on the front side of the carrier vehicle.

[0017] Compared with the prior art, the utility model has the advantages that:

[0018] 1. The utility model discloses a carrying vehicle carries multiple independent running grinding parts, which significantly improves the efficiency of grinding operation. Each grinding part can be independently lifted to flexibly cope with different ground and grinding requirements. Meanwhile, multiple grinding parts work in parallel, which greatly shortens the grinding period and significantly improves the efficiency of floor grinding operation. In addition, the independent lifting mechanism ensures the accurate adhesion of the grinding mechanism and the surface to be ground, improving the grinding quality.

[0019] 2. The partial overlap design of the grinding path of the adjacent grinding mechanism working surface effectively avoids the grinding blind area and ensures the uniform grinding of the floor surface. This feature is particularly important for projects that pursue high-quality grinding effect, which can significantly reduce the number of repeated grinding and improve the operation efficiency.

[0020] 3. The complete overlap of the adjacent edges of the grinding path of the adjacent two working surfaces further enhances the continuity and uniformity of grinding. This design not only eliminates the grinding gap, but also makes the grinding process more smooth, which helps to achieve seamless grinding effect and improve the overall appearance of the floor.

[0021] 4. The lifting mechanism adopts a pry bar hinged on the carrying vehicle, which not only has a simple structure and is easy to maintain, but also can stably realize the lifting action of the grinding mechanism. The pry bar design makes the lifting process more stable, reduces the vibration of the grinding mechanism, and improves the grinding precision and operation safety.

[0022] 5. The design of the grinding mechanism working surface vertically downward under the action of gravity ensures the natural adhesion of the grinding mechanism and the surface to be ground during grinding. This natural adhesion state helps to reduce the grinding resistance, improve the grinding efficiency, and also helps to maintain the stability and service life of the grinding mechanism.

[0023] 6. The use of a telescopic rod as a driving part not only simplifies the structure of the lifting mechanism, but also realizes precise control of the lifting action. The telescopic rod has a large telescopic range and fast response speed, which can meet the lifting height adjustment under different grinding requirements, improving the flexibility and adaptability of the grinding operation.

[0024] 7. The pry bar adopts a design of two L-shaped plates fixed by connecting rods, which enhances the rigidity and stability of the pry bar. At the same time, the way of hinging the grinding mechanism base and the front ends of the two L-shaped plates makes the lifting action more stable, reduces the shaking and deviation of the grinding mechanism, and improves the grinding precision.

[0025] 8. The symmetrical installation of two groups of lifting lugs and U-shaped clamping cavities on the grinding mechanism base provides a stable connection point for the hinge of the grinding mechanism and the pry bar. This connection method is easy to install and disassemble, and can withstand large force and torque, ensuring the stability and safety of the grinding mechanism during lifting.

[0026] 9. The fixed shaft connecting the tail ends of the two L-shaped plates provides a stable hinge point for the telescopic rod's extension and retraction. This design not only simplifies the structure of the lifting mechanism but also improves the stability and reliability of the telescopic rod during lifting, ensuring the precision and smoothness of the grinding mechanism's lifting action.

[0027] 10. The grinding sections are arranged in a triangular pattern at the front of the transport vehicle, optimizing the spatial layout of the grinder and allowing it to cover a larger floor area simultaneously. This layout not only improves grinding efficiency but also makes the grinding process more uniform and continuous, contributing to high-quality floor grinding results. At the same time, the triangular layout enhances the stability and safety of the grinder, ensuring smooth operation during work. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figs. 1-2 In this embodiment of the invention, a multi-head floor grinder is provided to improve the efficiency and coverage of floor grinding. The grinder mainly includes a transport vehicle 1 and multiple independently operable grinding heads 2 mounted on the transport vehicle 1.

[0034] The transport vehicle 1 serves as the support and mobile platform for the entire grinding machine, responsible for moving the grinding machine to the area to be ground. It can be driven directly by an operator or remotely controlled. Multiple grinding units 2 are installed on the transport vehicle 1, each of which operates independently and can perform lifting and grinding operations separately.

[0035] Each grinding unit 2 comprises a grinding mechanism 21 and a lifting mechanism 22. The grinding mechanism 21 is a component for directly grinding the floor, and different types of grinding plates or grinding discs can be selected according to requirements. The lifting mechanism 22 is used to adjust the distance between the working surface of the grinding mechanism 21 and the surface to be ground, so that the grinding mechanism 21 can closely contact or separate from the floor surface.

[0036] The lifting mechanism 22 comprises a pry bar 221 hinged to the carrier vehicle 1, and the base 212 of the grinding mechanism 21 is hinged to the pry end of the pry bar 221. A driving member is installed on the driving end of the pry bar 221, which can drive the pry end to swing up and down, thereby driving the grinding mechanism 21 to perform lifting action. The driving member is preferably a telescopic rod 222, which is preferably an electric cylinder. The two ends of the telescopic rod 222 are respectively hinged to the carrier vehicle 1 and the driving end of the pry bar 221, and the swinging of the pry bar 221 is realized by the extension and retraction of the telescopic rod 222.

[0037] The structure of the pry bar 221 comprises two L-shaped plates 2211, and the middle parts of the two L-shaped plates 2211 are fixed to each other by a connecting rod 2212, forming a stable structure. The base 212 of the grinding mechanism 21 is hinged to the front ends of the two L-shaped plates 2211 at the same time, so that when the pry bar 221 swings, the grinding mechanism 21 can move up and down accordingly. The extension end of the telescopic rod 222 is hinged to the fixed shaft 2213 connected between the tail ends of the two L-shaped plates 2211, and the swinging of the pry bar 221 is driven by the extension and retraction of the telescopic rod 222.

[0038] On the base 212 of the grinding mechanism 21, two sets of lifting lugs 2121 are symmetrically installed, and each set of lifting lugs 2121 forms a U-shaped clamping cavity. The front ends of the two L-shaped plates 2211 are respectively inserted into the corresponding clamping cavities and are hinged to the lifting lugs 2121. This hinging mode enables the grinding mechanism 21 to be stably connected to the pry bar 221 and to maintain a stable posture during lifting.

[0039] In addition, in order to improve the grinding efficiency and coverage area, the grinding units 2 are arranged in three groups, and the three groups of grinding units 2 are distributed in a triangular shape on the front side of the carrier vehicle 1. This layout enables the grinding machine to cover a larger floor area during movement, thereby further improving the grinding efficiency.

[0040] During grinding, the grinding paths between the working surfaces of the two adjacent grinding mechanisms 21 partially overlap to ensure that the entire floor area is evenly ground. Preferably, the edges of the grinding paths of the two adjacent working surfaces overlap with each other to avoid missing grinding.

[0041] When the grinding operation is needed, the operator can start the electric hydraulic cylinder to make the pry bar 221 swing and drive the grinding mechanism 21 to descend, so that the working surface of the grinding mechanism 21 closely abuts the floor surface to be ground. Then, the carrier vehicle 1 can move while the plurality of grinding parts 2 synchronously perform the grinding operation. When the grinding of a region is completed, the operator can again start the telescopic rod 222 to make the grinding mechanism 21 rise and be separated from the floor surface, and then the carrier vehicle 1 moves to the next region to be ground.

[0042] In summary, the multi-head floor grinder has the advantages of simple structure, convenient operation, high grinding efficiency, large coverage area and the like, and is suitable for grinding operations of various large floors.

[0043] As shown in Fig. 3 The carrier vehicle 1 has a corresponding triangular shape, which can provide better stability, especially when the load is heavy or when driving on uneven roads, so that the carrier vehicle 1 can be kept stable. At the same time, the triangular structure is compact, which can make more effective use of the chassis space, so that the carrier vehicle 1 is more compact as a whole.

[0044] Three wheels are installed on the chassis, in a front one rear two installation mode. The rear two are drive wheels 12, and the front one is a universal wheel 11, and each drive wheel 12 is provided with a drive motor. The universal wheel 11 as the front wheel is responsible for steering, and the drive wheel 12 as the rear wheel is responsible for providing support and propulsion force, so that the carrier vehicle 1 is more flexible to control. At the same time, the three wheels disperse the weight of the carrier vehicle 1, so that the pressure borne by each wheel is more uniform, prolonging the service life of the wheels.

[0045] The triangular chassis and the three wheels cooperate with each other, which can effectively reduce unnecessary lever length, so that the overall length of the carrier vehicle 1 is effectively reduced. More importantly, this design strategy also significantly reduces the turning radius of the carrier vehicle 1. In a narrow or complex operating environment, a smaller turning radius means that the vehicle can turn and move more flexibly, greatly improving the convenience and efficiency of operation. Whether it is to shuttle in a narrow warehouse passage or to grind in a complex construction site, the carrier vehicle 1 can easily cope with various challenges thanks to its excellent turning performance.

[0046] In use, the two drive motors are started synchronously to drive the carrier vehicle 1 to move along a straight line. When there is a speed difference or the two drive motors are reversely rotated, the carrier vehicle 1 can move along a curve or rotate in place under the cooperation of the universal wheel 11, thereby completing the grinding work of grinding regions of different shapes and improving the application range of the utility model.

[0047] The specific use process of the utility model is as follows:

[0048] The operator controls the carrier 1 to move to the area to be ground, and then starts to put down each grinding unit 2 as needed. First, the cylinder serving as the telescopic rod 222 is elongated, and each base 212 is gradually put down, at which time the base 212 slightly swings on the plumb line under the cooperation of the lug 2121 and the L-shaped plate 2212, and then the working surface is downward under the action of gravity and adheres to the surface to be ground. At the same time, the cylinder is released from the brake and can freely extend and retract, so that the working surface independently adheres to the surface to be ground under the gravity of the whole grinding mechanism 21, and the downward grinding pressure is provided by the gravity of the whole grinding mechanism 21. The motor 211 is started to drive the grinding disc on the base 212 to start rotating and grinding, and then the carrier 1 starts the grinding work according to the corresponding route. When the grinding is completed or it is needed to close a grinding mechanism 21, the cylinder is restarted, the prying end of the L-shaped plate 2211 is tilted upward, and the corresponding grinding mechanism 21 is lifted away from the ground. Then it is transferred to the next area to be ground to perform the grinding work.

[0049] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
