Description

Technical Field

[0001] The present invention relates to the technical field of concrete road surface finishing in coal mines, and specifically relates to a concrete road surface construction finishing machine. Background Art

[0002] A finishing machine is a mechanical device used for preliminary surface treatment of concrete road surfaces. The working principle of the finishing machine is that the grinding disc rotates driven by an engine. The grinding disc rotates at a relatively low speed, pushing and leveling the materials on the surface of the concrete, eliminating the pits and protrusions on the surface of the concrete road surface after pouring, and performing preliminary leveling and finishing operations on the concrete surface; in coal mining areas, in order to facilitate the driving of coal transport vehicles, it is necessary to build concrete road surfaces, and the use of a finishing machine can be used for the preliminary forming of concrete road surfaces.

[0003] Existing finishing machines for concrete road surface treatment are usually hand-held or ride-on types, both of which are used for horizontal road surface treatment. For the inclined slope sections on both sides of the road, when the ride-on finishing machine operates with people on an inclined surface, it is easy to roll over, and the energy consumption for driving up and down the inclined road surface is excessive. Therefore, only a hand-held finishing machine can be relied on for treatment. However, due to the inclined road surface, multiple people are required to simultaneously pull and push the finishing machine up and down. Compared with horizontal road surface treatment, there are problems of consuming manpower and being troublesome to operate, and there is a lack of a general-purpose finishing machine that can be conveniently used on both horizontal and inclined road surfaces.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. For this coal mine concrete road surface construction troweling machine, by setting a traction mechanism, the troweling mechanism is tractioned by the traction ropes on two rope winding rollers to connect the hollow protective frame. Two rodless cylinders drive two roller frames to move away from each other. The roller frames drive the two rope winding rollers to move away from each other, so that the two traction ropes and the hollow protective frame form a triangular area. During the process of the wheels rotating to drive the frame to travel, the troweling mechanism is pulled by the traction ropes to move and automatically trowel the inclined road surface. The length of the traction ropes is adjusted by winding or unwinding the rope winding rollers, and then the position of the troweling mechanism on the inclined road surface is adjusted to perform a comprehensive troweling treatment on the inclined road surface.

[0019] 2. For this coal mine concrete road surface construction troweling machine, by setting a rotating ring and a bearing, after the troweling treatment of the inclined road surface is completed, the troweling mechanism is picked up and installed on the connecting frame by borrowing the fixed shaft. The rotating motor drives the gear to rotate. The gear drives the rotating ring to rotate through the rack. The rotating ring rotates relative to the central column through the bearing, and drives the troweling mechanism to move from one side of the frame to the rear side of the frame through the connecting mechanism, so that the troweling mechanism is used for troweling the horizontal road surface at the rear side of the frame. The position of the troweling mechanism can be adjusted by the rotation of the rotating ring, and the working state of the troweling mechanism is switched for the horizontal road surface and the inclined road surface, achieving the effect of being applicable to both the horizontal road surface and the inclined road surface.

[0020] 3. For this coal mine concrete road surface construction troweling machine, by setting a connecting mechanism and a suspension mechanism, when concrete adheres to the bottom of the grinding disc or the grinding disc needs to be maintained, the telescopic cylinder contracts to apply a pulling force to the connecting frame through the fixed ring, so that the connecting frame rotates upward around the first pin shaft. The connecting frame drives the troweling mechanism to move upward through the fixed shaft, and hooks the hook on the rear side wall of the hollow protective frame. The hollow protective frame is pulled by the suspension rope to rotate upward relative to the connecting frame with the fixed shaft as the axis. The hollow protective frame drives the grinding disc to rotate, so that the grinding disc rotates from the horizontal state to the vertical state, which is convenient for cleaning the concrete on the surface of the grinding disc from the rear side and maintaining the grinding disc.

[0021] 4. The concrete pavement troweling machine for this coal mine, by setting a fixed shaft, a curved groove and a pressing block, the fixed shaft is detachably connected to the connecting frame by inserting into the curved groove, which is convenient for the troweling mechanism to be connected and used with the connecting frame when treating a horizontal pavement, and to be detached and towed when treating an inclined pavement. After the fixed shaft is inserted into the curved groove, the screw rod is driven to rotate by a knob, the screw rod rotates and moves downward through the screw hole, and pushes the pressing block to move downward to squeeze the fixed shaft, and the pressing block restricts the fixed shaft from falling off the curved groove, enhancing the stability of the connection between the fixed shaft and the connecting frame.

[0034] As Figures 1 to 8 shown, the concrete pavement troweling machine for coal mines in this embodiment includes a central column 1. A machine case 2 is installed at the top of the central column 1. A bottom plate 3 is connected to the bottom of the central column 1. A frame 4 is connected to the bottom of the bottom plate 3. A bearing 5 is installed on the outer side wall of the central column 1 above the bottom plate 3. A rotating ring 6 is installed outside the bearing 5. The rotating ring 6 is in a circular ring shape. One side of the rotating ring 6 is connected to a connecting mechanism 7. A traction mechanism 8 is installed on the upper surface of the connecting mechanism 7, which is used for remotely traction of the troweling mechanism 9 when troweling an inclined road surface. One side of the connecting mechanism 7 away from the rotating ring 6 is connected to a troweling mechanism 9. The rear side wall of the machine case 2 is connected to a suspension mechanism 10, which is used for traction of the troweling mechanism 9 to keep it in an upright state, making it more convenient for maintenance and cleaning of the grinding disc 97;

[0035] A rack 61 is arranged on the outer surface of the rotating ring 6. There is no rack 61 on the outer side wall of the rotating ring 6 near the connecting seat 71, and it is directly connected to the connecting seat 71. A gear 62 is meshed and connected to one side of the rotating ring 6. The upper surface of the gear 62 is connected to a rotating motor 63. The rotating motor 63 is installed at the bottom of the machine case 2 on one side of the central column 1. The shaft end of the rotating motor 63 is connected to the gear 62. The rotating motor 63 is essentially a motor with a forward and reverse circuit, which is used to drive the rotating ring 6 to rotate bidirectionally. The rotating ring 6 is rotationally connected to the central column 1 through the bearing 5. By driving the gear 62 to rotate through the rotating motor 63, the gear 62 drives the rotating ring 6 to rotate through the rack 61. The rotating ring 6 rotates relative to the central column 1 through the bearing 5. By rotating the rotating ring 6, the position of the troweling mechanism 9 can be adjusted, and the working state of the troweling mechanism 9 can be switched for horizontal and inclined road surfaces, achieving the effect of being universal for horizontal and inclined road surfaces;

[0036] The connecting mechanism 7 includes a connecting seat 71 installed on the side wall of the rotating ring 6. An installation groove 72 is opened on the upper surface of the connecting seat 71. Installation plates 73 are connected to both sides of the connecting seat 71. The bottom surface of the installation groove 72 is flush with the upper surface of the installation plate 73, which is used for installing a rodless cylinder 85. The rear side wall of the connecting seat 71 is connected to a first hinge seat 74. A connecting frame 75 is connected to the inside of the first hinge seat 74. The fixed shaft 92 of the troweling mechanism 9 is directly detachably connected to the connecting frame 75. A first pin shaft 76 penetrates through the first hinge seat 74 and the connecting frame 75. A vertical plate 77 is vertically connected to the upper surface of the connecting seat 71, which is used for installing a telescopic cylinder 79.

[0037] Specifically, a curved groove 751 is formed inside one side of the connecting frame 75 away from the first hinge seat 74. The curved groove 751 extends to both side walls of the connecting frame 75. A groove 752 is formed inside the connecting frame 75 above the curved groove 751. When the pressing block 753 does not press the fixed shaft 92, it contracts inside the groove 752. The pressing block 753 is movably inserted into the groove 752. A screw hole 754 is formed inside the connecting frame 75 above the groove 752. A screw rod 755 is disposed through the screw hole 754. The outer diameter of the screw rod 755 is adapted to the inner diameter of the screw hole 754. The screw rod 755 passes through the screw hole 754 and is connected to the pressing block 753. The top of the screw rod 755 is connected to a knob 756.

[0038] Further, the number of the telescopic cylinders 79 is two, which are respectively used to control the up and down rotation of the connecting frame 75 around the first pin shaft 76. A second hinge seat 78 is connected to the rear side wall of the vertical plate 77. A telescopic cylinder 79 is connected to the inner side of the second hinge seat 78. A second pin shaft 710 is disposed through between the second hinge seat 78 and the telescopic cylinder 79. A fixed ring 711 is connected to the middle of the upper surface of the connecting frame 75. The connecting mechanism 7 is used to connect the rotating ring 6 and the troweling mechanism 9. The number of the connecting frames 75 is two, and the two connecting frames 75 are symmetric about the left and right with respect to the connecting seat 71. The two connecting frames 75 are respectively rotatably connected to the two first hinge seats 74 through the first pin shaft 76. When the connecting frame 75 inclines downward, the grinding disc 97 of the troweling mechanism 9 connected to the connecting frame 75 can contact the road surface for troweling treatment. When the connecting frame 75 inclines upward, the troweling mechanism 9 is lifted, which is convenient for the cleaning and maintenance of the grinding disc 97 and also convenient for the driving of the machine frame 4. The front side of the telescopic cylinder 79 is rotatably connected to the second hinge seat 78 through the second pin shaft 710. The rear side of the telescopic cylinder 79 is connected to the connecting frame 75 through the fixed ring 711. By the telescopic movement of the telescopic cylinder 79, a force is applied to the connecting frame 75 through the fixed ring 711, so that the connecting frame 75 rotates upward or downward around the first pin shaft 76.

[0039] Furthermore, the traction mechanism 8 includes a roller frame 81. Inside the roller frame 81, a rope winding roller 82 is installed. The rope winding roller 82 is rotatably connected to the roller frame 81. A traction rope 83 is wound around the surface of the rope winding roller 82. On one side of the roller frame 81, a traction motor 84 is installed. The shaft end of the traction motor 84 is connected to the rope winding roller 82 and is used to drive the rope winding roller 82 to rotate for paying out or winding up the traction rope 83. At the bottom of the roller frame 81, a rodless cylinder 85 is connected. The number of the rope winding rollers 82 and the rodless cylinders 85 is two. The bottom of the roller frame 81 is connected to the moving part of the rodless cylinder 85. The two rodless cylinders 85 drive the two roller frames 81 to move away from each other. The roller frames 81 drive the two rope winding rollers 82 to move away from each other, so that the two traction ropes 83 and the hollow protective frame 98 form a triangular area, which is convenient for the frame 4 to effectively drive the plastering mechanism 9 to move back and forth when traveling. One end of the traction rope 83 is wound around the rope winding roller 82, and the other end of the traction rope 83 is connected to the front side of the hollow protective frame 98. During the process of the wheels 41 rotating to drive the frame 4 to travel, the plastering mechanism 9 is pulled by the traction rope 83 to move and automatically plaster the inclined road surface. By cooperating with the rope winding roller 82 to wind up or pay out the traction rope 83, the length of the traction rope 83 is adjusted, and further the height position of the plastering mechanism 9 on the inclined road surface is adjusted to perform a comprehensive plastering treatment on the inclined road surface.

[0040] Furthermore, the plastering mechanism 9 includes a fixed seat 91. Fixed shafts 92 are connected to both side walls of the fixed seat 91. An annular groove 93 is formed on the outer surface of the fixed shaft 92. The middle part of the outer surface of the fixed shaft 92 is sunken due to the annular groove 93, which is convenient for inserting into the curved groove 751 through the annular groove 93 and simultaneously limiting the left and right positions of the fixed shaft 92 in the curved groove 751. Inside the fixed seat 91, a plastering motor 94 is installed. The plastering motor 94 is electrically connected to the controller 22 and the fuel generator 21 through a cable 24. The shaft end of the plastering motor 94 is connected to a speed reducer 95. The bottom of the speed reducer 95 is connected to a rotating shaft 96. The bottom of the rotating shaft 96 is connected to a grinding disc 97. A hollow protective frame 98 is connected to the outer edge of the fixed seat 91.

[0041] Furthermore, the outer diameter of the fixed shaft 92 is adapted to the inner diameter of the curved groove 751. The fixed shaft 92 is movably inserted into the curved groove 751 through the annular groove 93. The fixed shaft 92 is inserted into the curved groove 751 to form a rotational connection with the connecting frame 75. The fixed shaft 92 is detachably connected to the connecting frame 75 by inserting into the curved groove 751, which is convenient for the plastering mechanism 9 to be connected and used with the connecting frame 75 when treating a horizontal road surface and to be detached for traction when treating an inclined road surface.

[0042] Further, the bottom of the screw rod 755 is connected to the pressing block 753. The screw rod 755 passes through the screw hole 754 and is threadedly connected to the connecting frame 75. When the pressing block 753 moves downward to contact the upper surface of the fixed shaft 92, after the fixed shaft 92 is inserted into the curved groove 751, the screw rod 755 is driven to rotate by the knob 756. The screw rod 755 rotates and moves downward through the screw hole 754, and pushes the pressing block 753 to move downward to squeeze the fixed shaft 92. The pressing block 753 restricts the fixed shaft 92 from falling off the curved groove 751, enhancing the stability of the connection between the fixed shaft 92 and the connecting frame 75.

[0043] Further, the suspension mechanism 10 includes a suspension rope 101. One end of the suspension rope 101 is connected to the rear side wall of the chassis 2 by a connecting ring 102. The suspension rope 101 and the connecting ring 102 can be untied. The other end of the suspension rope 101 is connected to a hook 103. The suspension rope 101 is hooked to the rear side of the hollow protective frame 98 through the hook 103. By pushing the hollow protective frame 98 to turn upward relative to the connecting frame 75 with the fixed shaft 92 as the axis, the hook 103 is hooked on the rear side wall of the hollow protective frame 98. The suspension rope 101 is used to pull and make the grinding disc 97 stably in an upright state, which is convenient for cleaning the concrete on the surface of the grinding disc 97 from the rear side and maintaining the grinding disc 97. In addition, in the case where the subsequent plastering mechanism 9 is prone to displacement due to factors such as friction, or when the plastering mechanism 9 cannot be directly supported manually, one end of the suspension rope 101 can be untied from the connecting ring 102, and the hook 103 at the other end of the suspension rope 101 is hooked on the hollow protective frame 98. When a person stands at the downhill position of the inclined road surface to be constructed and pulls the suspension rope 101, together with the two traction ropes 83, the plastering mechanism 9 can be positioned and pulled in three directions by the three ropes, overcoming the friction and ensuring the precise movement of the plastering mechanism 9 without the need for staff to operate on the inclined road surface.

[0044] Further, a fuel generator 21 is installed inside the chassis 2. A controller 22 is installed inside the chassis 2 on one side of the fuel generator 21. A control panel 23 is installed on the outer side wall of the chassis 2 on one side of the controller 22, which is used to input instructions to control the start of plastering operations in different modes. A cable 24 is connected between the controller 22 and the plastering motor 94. A corrugated pipe can be sleeved outside the cable 24 to support the cable 24, preventing the cable 24 from contacting the road surface when connecting the plastering mechanism 9 and affecting the plastering.

[0045] Furthermore, wheels 41 are installed at the bottom of the frame 4. A wheel axle 42 runs through the middle of the wheels 41. A driving motor 44 is installed on the upper surface of the frame 4 above the wheel axle 42. A transmission group 43 is connected between the driving motor 44 and the wheel axle 42. The transmission group 43 consists of two transmission wheels and a transmission belt for driving connection between the two transmission wheels. The driving motor 44 drives the wheel axle 42 to rotate through the transmission group 43. The wheel axle 42 drives the wheels 41 to rotate, and the rotation of the wheels 41 drives the frame 4 to move forward. In addition, a steering assembly can be installed on one side of the wheels 41 for automatic steering of the frame 4 during driving, or a handle can be installed on the front side of the frame 4 for manual steering of the frame 4 during hand-pushing.

[0046] The usage method of this embodiment is as follows: When the user actually uses the screeding machine to process the horizontal road surface, first control the telescopic air cylinder 79 to extend. The telescopic air cylinder 79 drives the connecting frame 75 to move downward relative to the connecting seat 71 around the first pin shaft 76 through the fixed ring 711. The connecting frame 75 drives the screeding mechanism 9 to move downward until the bottom of the grinding disc 97 contacts the road surface. Then start the fuel generator 21, input commands on the control panel 23, and turn on the horizontal road surface screeding mode. At this time, the controller 22 controls the screeding motor 94 to start. The screeding motor 94 drives the rotating shaft 96 to rotate through the speed reducer 95. The rotating shaft 96 drives the grinding disc 97 to rotate. The rotating grinding disc 97 pushes and levels the materials on the surface of the concrete, eliminating the potholes and protrusions on the surface of the concrete road surface after pouring. At the same time, the driving motor 44 drives the wheel axle 42 to rotate through the transmission group 43. The wheel axle 42 drives the wheels 41 to rotate. The rotation of the wheels 41 drives the frame 4 to travel back and forth. The frame 4 drives the connecting mechanism 7 to pull the screeding mechanism 9 to move, and screed the entire horizontal road surface. When screeding the inclined road surface, the rotating motor 63 drives the gear 62 to rotate. The gear 62 drives the rotating ring 6 through the rack 61. The rotating ring 6 rotates relative to the central column 1 through the bearing 5, and moves the connecting mechanism 7 and the screeding mechanism 9 from the rear side of the frame 4 to the side of the frame 4 close to the inclined road surface. Then turn the knob 756. The knob 756 drives the screw rod 755 to rotate, so that the screw rod 755 rotates and moves upward in the screw hole 754. The screw rod 755 drives the pressing block 753 to move upward and retract into the groove 752. Then lift the screeding mechanism 9 to take out the fixed shaft 92 from the curved groove 751, place the grinding mechanism on the inclined road surface, and then start the inclined road surface screeding mode from the control panel 23. The two rodless air cylinders 85 drive the two roller frames 81 to move away from each other. The roller frames 81 drive the two rope winding rollers 82 to move away from each other, so that the two traction ropes 83 and the hollow protective frame 98 form a triangular area. At the same time, the screeding motor 94 drives the grinding disc 97 to rotate. Then the rotation of the wheels 41 drives the frame to travel back and forth in a straight line, so that the grinding disc 97 screeds the inclined road surface. The traction motor 84 drives the rope winding roller 82 to rotate, so that the traction rope 83 is unwound, and the length of the traction rope 83 is adjusted, thereby adjusting the position of the screeding mechanism 9 on the inclined road surface and screeding the entire inclined road surface;After the finishing of the inclined road surface, the traction motor 84 drives the rope winding roller 82 to wind up, lifting the finishing mechanism 9 from the road surface and placing it on the connecting frame 75, so that the fixed shaft 92 is inserted into the curved groove 751 through the annular groove 93. Then, the knob 756 drives the screw rod 755 to rotate. The screw rod 755 rotates and moves downward through the screw hole 754, and pushes the pressing block 753 to move downward to squeeze the fixed shaft 92, and the pressing block 753 restricts the fixed shaft 92 from falling off the curved groove 751. When it is necessary to clean the concrete attached to the bottom of the grinding disc 97 or maintain the grinding disc 97, the telescopic cylinder 79 is controlled to contract to apply a pulling force to the connecting frame 75 through the fixed ring 711, so that the connecting frame 75 rotates upward around the first pin shaft 76. The connecting frame 75 drives the finishing mechanism 9 to move upward through the fixed shaft 92, and then pushes the hollow protective frame 98 to rotate upward relative to the connecting frame 75 with the fixed shaft 92 as the axis. The hook 103 is hooked on the rear side wall of the hollow protective frame 98, and the hanging rope 101 is used for traction to make the grinding disc 97 stably in an upright state, which is convenient for cleaning the concrete on the surface of the grinding disc 97 from the rear side and maintaining the grinding disc 97.;
