Description

Technical Field

[0001] The invention belongs to the field of building construction equipment, and in particular relates to ground leveling equipment. Background Art

[0002] A floor grinder is a commonly used piece of construction equipment. It primarily uses a motor to drive the grinding disc, utilizing the friction between the grinding blocks or discs on the disc and the ground to grind, polish, and clean the ground. The machine's gravity also helps enhance the grinding effect, leaving the ground smooth and shiny. Floor grinders are categorized by their drive method: electric grinders, fuel-powered grinders, and pneumatic grinders. Electric grinders are the most common type, offering ease of operation, low noise, and minimal pollution. Fuel-powered grinders are powerful and suitable for locations without power supply, but they can be noisy and polluting. Pneumatic grinders are explosion-proof and offer excellent safety features, making them suitable for use in special environments.

[0003] At present, common electric grinders complete their operations by hand-holding, and the relative positions of the hand-holding mechanism and the grinding mechanism are basically fixed, such as the floor grinding robot disclosed in CN210060644U, a mobile floor grinder disclosed in CN221248051U, and a floor grinder grinding head height adjustment mechanism disclosed in CN212371796U. Although such electric grinders can achieve the purpose of processing the surface quality of the floor, there are some problems in actual operation. For example, due to the volume of the equipment in the front and rear directions, the installation of the walking mechanism and the armrest mechanism will inevitably occupy a considerable amount of space, so a large margin is left at the corner position, which will lead to dead angles, and it is also difficult to process the corner positions of some triangular structures, thereby affecting construction efficiency and construction quality.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Examples, such as Figures 1-11As shown, the present invention provides a ground leveling equipment, including a motor mechanism 1, wherein the motor mechanism 1 includes a motor and a motor seat, the motor mechanism 1 is arranged on a grinding machine case 2 with a rectangular cross-section, the motor seat is connected to the grinding machine case 2 by screws / bolts, and the interior of the grinding machine case 2 is provided with a plurality of grinding cutter discs 3 that are transmission-connected to the motor mechanism, and the bottom surface of the grinding cutter disc 3 is provided with a grinding blade 4, and the grinding working surface formed under all the grinding cutter discs 3 is approximately a rectangular working surface, which is conducive to improving the grinding efficiency; a walking mechanism 5 is provided on one side of the grinding machine case 2, the walking mechanism 5 includes a wheel axle, a pair of walking wheels are provided on the wheel axle, and an armrest mechanism 6 is provided above the walking mechanism 5. In order to improve the efficiency of indoor operation of this equipment, a cross bridge 51 is provided in the middle of the walking mechanism 5 provided by the present invention. The internal horizontal direction of the cross bridge 51 is used to install the wheel axle. A rotating mechanism 7 is provided on the top of the cross bridge 51. The rotating mechanism 7 is rotatably set on the chassis mechanism 8. The relative height of the chassis mechanism 8 and the motor mechanism 1 remains unchanged but the relative angle is adjustable. The chassis mechanism 8 includes a rear transmission port 82 that cooperates with the rotating mechanism 7 and a front transmission port 81 that cooperates with the motor mechanism 1. The chassis mechanism 8 adjusts the relative position of the chassis mechanism 8 and the grinding machine box 2 by rotating around the front transmission port 81, and the rotating mechanism 7 adjusts the walking direction of the walking mechanism 5 by rotating around the rear transmission port 82.

[0033] In this equipment, the chassis mechanism 8 can be adjusted to the side of the grinding machine box 2 through the adjustment function of the chassis mechanism 8 and the grinding machine box 2, and the walking direction of the walking mechanism 5 is adjusted by the rotating mechanism 7 so that the walking direction of the walking mechanism 5 is parallel to the wall surface, so that the grinding machine box 2 can walk along the wall. The walking mechanism 5 and the chassis mechanism 8 can be switched in time near the corner, which effectively reduces the turning diameter change and is conducive to narrowing the operation blind spot; for triangular corners, only the angle between the chassis mechanism 8 and the grinding machine box 2 can be adjusted, and the direction of the walking mechanism 5 remains unchanged. The ground in the triangular area can be processed by pulling and reciprocating this equipment. It has a reasonable design, strong operating capacity and high comprehensive utilization rate.

[0034] In order to facilitate the adjustment of the on-site steering performance of the walking mechanism 5, the rotating mechanism 7 provided by the present invention includes a center seat 71, a ring slider 72 is provided on the side of the center seat 71, a center shaft 73 is provided on the top of the ring slider 72, a T-shaped sleeve 74 is provided on the center shaft 73, and the T-shaped sleeve 74 and the center shaft 73 can be connected by a key to facilitate the establishment of synchronous rotation conditions; a plurality of key-shaped openings 75 are provided on the edge of the T-shaped sleeve 74, and a plurality of positioning grooves 83 corresponding to the key-shaped openings 75 are provided on the rear transmission opening 82, and a handle 76 hinged to the T-shaped sleeve 74 is provided, and a positioning block 77 sleeved thereon is provided on the handle 76, and the positioning block 77 can rotate on the handle 76, and the positioning block 77 is used to connect the key-shaped opening 75 and the positioning groove 83. Among them, the flip handle 76 is flipped to one side of the center seat 71 when not in use, and the positioning block 77 locks the positioning groove 83 corresponding to the key-shaped mouth 75, so that the center seat 71 and the rear transmission mouth 82 do not rotate relative to each other, thereby allowing the walking mechanism 5 to have a certain walking direction; on the contrary, the flip handle 76 is lifted from the side of the center seat 71, and the locking relationship between the key-shaped mouth 75 and the positioning groove 83 of the positioning block 77 is released. By rotating the flip handle 76, the center seat 71 can be rotated relative to the rear transmission mouth 82, thereby changing the walking direction of the walking mechanism 5. After adjusting the direction, the flip handle 76 and the positioning block 77 are reset to ensure that the walking mechanism 5 has a better walking ability.

[0035] In order to improve the space utilization of the present invention, the chassis mechanism 8 provided by the present invention includes a chassis frame 84, the surface area of ​​the chassis frame 84 is smaller than the surface area of ​​the grinding machine box 2, the front transmission port 81 is arranged on the chassis frame 84, and the upper surface of the front transmission port 81 is limited by the edge of the motor seat to control the height. The chassis frame 84 is provided with a side plate frame 85 at the end deviating from the motor mechanism 1, and a guide rail frame 86 is provided at the end of the side plate frame 85. The guide rail frame 86, the side plate frame 85 and the chassis frame 84 are connected in a Z shape, and the inner side of the guide rail frame 86 is provided with a guide groove 87 that can slide back and forth with the rotating mechanism 7. The spatial structure formed by the guide rail frame 86, the side panel frame 85, and the chassis frame 84 allows sufficient height for the running wheels. In addition, the wheelbase of the running mechanism 5 is larger than the assembly spacing between the running mechanism 5 and the grinding machine housing 2. The guide groove 87 reserves a certain amount of horizontal adjustment margin for the rotating mechanism 7 and the running mechanism 5, allowing the running mechanism 5 to move horizontally for a certain distance before adjusting its direction. The turning radius of the running mechanism 5 allows the running mechanism 5 to safely pass through the overhead space below the chassis mechanism 8, so the running mechanism 5 can be rotated and adjusted on the spot within a limited range. After the running mechanism 5 is rotated and adjusted on the spot, the assembly spacing between the running mechanism 5 and the grinding machine housing 2 is restored. Since its wheel radius is smaller than the width below the chassis mechanism 8, the running wheels of the running mechanism 5 close to the grinding machine housing 2 can be relatively concealed below the chassis mechanism 8 and have safe walking conditions. Therefore, on the basis of realizing the switching between the walking direction and the grinding direction, this equipment has a good space coordination effect, a high space utilization rate, and is conducive to ensuring the performance of the equipment indoors.

[0036] In order to improve construction efficiency, the angle between the chassis mechanism 8 and the grinding machine box 2 provided by the present invention can be adjusted in a motorized manner. Specifically, the front end of the chassis frame 84 provided by the present invention is provided with a transmission box 88 connected to the front transmission port 81, and the top of the transmission box 88 is provided with a stepper motor 89. The interior of the transmission box 88 is provided with a driving gear 810 that is transmission-connected to the stepper motor 89. The transmission side of the driving gear 810 is provided with a driven gear 811, and the driven gear 811 is transmission-connected to the bottom outer side of the motor mechanism 1. Among them, the stepper motor 89 inputs power to the driving gear 810, so that the driven gear 811 is driven and drives the chassis frame 84 and the grinding machine box 2 to rotate relative to each other. At the same time, the meshing action of the driving gear 810 and the driven gear 811 plays a role in preventing reverse rotation, which is conducive to improving the safety and reliability of the chassis frame 84 and the grinding machine box 2 during operation. The overall area of ​​the transmission case 88 and the chassis frame 84 is smaller than the surface of the grinding machine case 2. Therefore, if the chassis frame 84 and the grinding machine case 2 move relative to each other, the edge of the chassis frame 84 will not be mounted on the indoor wall. In addition, the grinding machine case 2 and the wall can have a smaller working distance, thereby further reducing the working blind spot area.

[0037] In order to improve the grinding operation efficiency of the equipment in the walking state, the chassis mechanism 8 provided by the present invention includes a telescopic frame, the telescopic frame includes a pair of columns 812 and a movable top plate 813 connected to the columns 812, the movable top plate 813 includes a pair of horizontal rods integrated with the columns 812, the other end of the horizontal rod is a circular plate, the middle of the circular plate is the rear transmission port 82, the column 812 is movably arranged on the inner side of the chassis frame 84, and the inner side of the chassis frame 84 is provided with a telescopic spring 814 connected to the column 812 in the front-to-back direction, and the rear transmission port 82 is arranged on the movable top plate 813. The chassis mechanism 8 provided by the present invention adopts a combined frame structure as a whole, and a rotatable system is composed of a guide rail frame 86, a side plate frame 85 and a chassis frame 84, and a translational system is composed of a column 812 and a movable top plate 813. In the translational system, the telescopic spring 814 plays a balancing role, and the guide groove 87 and the guide rail frame 86 play a guiding role; the connecting part between the side plate frame 85 and the chassis frame 84 is a concave design, and at the same time, the inner wall of the chassis frame 84 near the front transmission port 81 is a circular arc surface, and the concave and arc surface provide front and rear limit conditions for the column 812; the concave provides an installation base for the telescopic spring 814; the telescopic spring 814 can produce obvious deformation when the staff pulls hard. In this way, the purpose of adjusting the real-time distance between the walking mechanism 5 and the grinding machine box 2 can be achieved by translating the telescopic frame, which is beneficial for the walking mechanism 5 to realize safe on-site rotation in a relatively limited area. The telescopic spring 814 provides a reset tension, so that the walking mechanism 5 can return to the original assembly spacing conditions, which is beneficial for controlling the overall space utilization of the equipment; at the same time, the telescopic spring 814 can play a certain shock-absorbing role, providing dynamic balance adjustment capability for the walking mechanism 5 and the grinding machine box 2, and the dynamic balance range is not more than 6 cm, so that the equipment has better construction performance.

[0038] In order to facilitate the assembly of the rotating mechanism 7, one end of the guide rail frame 86 provided by the present invention is open, so that the center seat 71 of the rotating mechanism 7 can be inserted into the guide rail frame 86 along the guide groove 87. In order to improve the space utilization of the present device, the actual length of the guide rail frame 86 is less than the maximum movement distance of the telescopic frame. In order to ensure that the end of the chassis mechanism 8 is closed, it serves as a safety protection mechanism. Specifically, the present invention provides two symmetrically distributed guide rods 815 at the end of the guide rail frame 86, and the end of the guide rod 815 is provided with an end plate 816. In this way, when the telescopic frame and the rotating mechanism 7 are translated to the farthest distance, the guide rod 815 is pulled out a certain length along the insertion and extraction surface between it and the guide rail frame 86, and the circumferential surface of the center seat 71 can be pressed against the end plate 816 without hitting the handrail mechanism 6 and the staff. After the telescopic frame and the rotating mechanism 7 are reset, the end plate 816 can be pressed against the end of the guide rail frame 86 again.

[0039] Considering that the device has multiple usage states, in order to facilitate a better handrail effect in different states, the present invention provides a pair of hinged support plates 817 for mounting the armrest mechanism 6 on the side of the chassis mechanism 8. The armrest mechanism 6 and the hinged support plates 817 can be flipped and adjusted. In this way, Figure 1 and Figure 4 As shown, the walking mechanism 5 is located on the rear side of the grinding machine box 2, and the armrest mechanism 6 can be designed to be inclined. Workers can hold both sides of the armrest mechanism 6 to control the forward and backward translation of the entire equipment; Figure 5 and Figure 7 As shown, if the walking mechanism 5 is located at the side of the grinding machine box 2, the armrest mechanism 6 can be straightened. The rod structure of the armrest mechanism 6 in the length direction can provide a hand-held node. The hand-held span is large but not greater than the horizontal length of the entire vehicle. The force is evenly distributed, which is convenient for workers to manually operate the equipment to perform ground leveling operations; Figure 8 As shown, when the device is not in use, the armrest mechanism 6 can be folded to the front side of the grinding machine box 2 without interfering with the motor mechanism 1, thereby effectively reducing the occupied volume of the equipment.

[0040] In order to improve the performance of the armrest mechanism 6, the armrest mechanism 6 provided by the present invention includes two rotating arms 61 that correspond to the hinge plates 817 one by one, and a triangular plate 62 is provided on the rotating arm 61. An armrest frame 63 is provided on the top of the triangular plate 62. The armrest frame 63 includes a pair of horizontal square tubes 631, and a plurality of vertical square tubes 632 are provided between the horizontal square tubes 631. A pair of adjustment holes 633 are provided on the vertical square tubes 632 at the ends. An inner square tube 634 that is nested with the vertical square tube 632 is provided below the adjustment hole 633. An adjustment bolt 635 that cooperates with the adjustment hole 633 is provided on the inner square tube 634. The adjustment bolt 635 is used to fix the insertion depth of the inner square tube in the vertical square tube. A handle rod 636 is provided at the end of the inner square tube 634. The end of the handle rod 636 is inserted into the two inner square tubes 634 located at both ends of the horizontal square tube 631. The handle rod 636 is a round rod for easy holding. The control side of the stepper motor 89 and the motor mechanism 1 are connected to the control board set on the armrest mechanism 6, wherein the rotating arm 61 provides a rotation adjustment node for the armrest mechanism 6 and the chassis mechanism 8; the top of the triangular plate 62 is flat and fixedly connected to the horizontal square tube 631, and the bottom corner of the triangular plate 62 is integrally formed with the rotating arm 61 to provide effective support for the armrest frame 63; the armrest frame 63 is a rectangular frame composed of multiple square tubes, which can provide multiple effective hand-held contours; for Figure 1 and Figure 4 In the state shown, the horizontal square tube 631 or the handle 636 of the handrail mechanism 6 can be directly held by the hand, so that the worker can push the device indoors. Figure 5 and Figure 7In the illustrated position, the armrest mechanism 6 can be straightened. For safety reasons, the inner square tube 634 can be pulled out to extend the reach of the armrest mechanism 6, thereby preventing potential hazards caused by close proximity to the equipment. The armrest mechanism 6 is shorter in the horizontal direction than the overall length of the equipment, which does not affect the equipment's ability to grind along a wall.

[0041] In order to effectively control the angle of the armrest mechanism 6, the inner contour of the triangular plate 62 provided by the present invention is nearly triangular. An outer cylinder 64 is provided on the inner side of the triangular plate 62, a push rod 65 is provided inside the outer cylinder 64, a return spring 66 connected to the push rod 65 is provided inside the outer cylinder 64, a positioning rod 67 is provided at the bottom of the push rod 65, a center hole 68 is provided inside the rotating arm 61 to engage with the positioning rod 67, a fixed shaft sleeve 818 is provided on the hinge plate 817 to engage with the rotating arm 61, and a plurality of pin holes 819 for engaging with the positioning rod 67 are provided on the side of the fixed shaft sleeve 818. Among them, the outer cylinder 64 provides a built-in space for the return spring 66, and the position of the positioning rod 67 in the center hole 68 can be adjusted by sliding the push rod 65 up and down, thereby changing the pin hole 819 that the positioning rod 67 actually engages with; Figure 5 and Figure 7 In the state shown, the positioning rod 67 is plugged into the pin hole 819 in the vertical direction. Figure 1 and Figure 4 In the state shown, the positioning rod 67 is plugged into the pin hole 819 in the tilting direction, thereby enabling the armrest mechanism 6 to obtain corresponding locking nodes at different angles, making it convenient to establish better handholding conditions according to different usage states, so as to better and safely complete the floor grinding operation.

[0042] Considering that the armrest mechanism 6 in this device is in most conditions Figure 1 and Figure 4 In the state shown, in order to improve the reliability and durability of the armrest mechanism 6, the chassis mechanism 8 provided by the present invention is provided with an anti-slip mechanism 9, which includes a fixed plate 91, a limiting shoulder 92 is provided on the top of the fixed plate 91, and a plug plate 93 is provided on one side of the limiting shoulder 92. The plug plate 93 cooperates with the socket 94 provided on the armrest mechanism 6, and a hinge 95 is provided on the edge of the limiting shoulder 92. The hinge 95 is provided with a flip buckle 96, and the flip buckle 96 can be flipped and buckled on the armrest mechanism 6. Among them, the fixed plate 91 is fixedly connected to the guide rail frame 86 by screws, and the limiting shoulder 92 provides a limiting support for one side of the triangle plate 62. By flipping the flip buckle 96 to the inner contour range of the triangle plate 62, the edge of the flip buckle 96 can be clamped on the triangle plate 62. In addition, the connection between the positioning rod 67 and the pin hole 819 can effectively improve the reliability of the armrest mechanism 6, thereby ensuring the performance of the device.
