[0005] The supporting frame is slidably connected with the transport frame inside, and a synchronous structure for stabilizing the transport frame is arranged on the top of the transport frame, the synchronous structure is provided with a transmission rod, and both ends of the transmission rod are fixedly connected with transmission bevel gears, the outer side of the transmission bevel gears is meshed with a balance rod, and the outer side of the balance rod is fixedly connected with a bevel gear ring, and the balance rod is meshed with the transmission bevel gear through the bevel gear ring, and the balance rod is provided with two balance rods, and the two balance rods are symmetrically distributed at both ends of the transmission rod, and both ends of the balance rod are fixedly connected with passive bevel gears;

[0006] A fixing structure for fixing the plate is arranged inside the transport frame.

[0007] Preferably, the transmission rod is rotatably connected to one side of the top of the transport frame, and the two balance rods are rotatably connected to the top of the transport frame. Two symmetrically distributed positioning sliders are fixedly connected to both ends of the transport frame, and the positioning sliders are slidably connected to the inside of the positioning slide groove.

[0008] Preferably, the passive bevel teeth arranged at both ends of the balance bar are meshed with the inner side of the rack, and the two balance bars are meshed with both ends of the transmission rod at the same time, so that the two balance bars rotate in opposite directions.

[0009] Preferably, the outer sides of the four independently distributed support columns provided on the support frame are all rotatably connected with positioning pulleys, and the positioning pulleys are rotatably connected to the two ends of the transport frame.

[0010] Preferably, two symmetrically distributed speed reducers are rotatably connected to both sides of the interior of the transport frame, and an elastic rotating shaft is provided at the connection between the speed reducer and the transport frame.

[0011] Preferably, the outer side of the bottom of the transport frame is rotatably connected to two symmetrically distributed support wheels, and the support wheels are composed of two independently distributed pulleys. The bottom of the transport frame is rotatably connected to four support rollers, and the two support rollers are arranged as a group and symmetrically distributed at the bottom of the transport frame.

[0012] Preferably, a first hydraulic rod is rotatably connected to one side of the transport frame, and a rotating rod is rotatably connected to the end of the first hydraulic rod, a positioning rod is fixedly connected to the end of the rotating rod, and the end of the rotating rod away from the positioning rod is rotatably connected to the inner side of the bottom of the transport frame, and two symmetrically distributed second hydraulic rods are fixedly connected to the bottom of the transport frame, and the inner ends of the two second hydraulic rods are fixedly connected to fixing plates.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The lifting and conveying frame of the automatic sawing table for stacking boards without foundation pit is provided with a synchronous structure. Through the connection of the transmission rod, two balancing rods can rotate synchronously. Since the balancing rods are engaged with the inner side of the rack, when the overall force of the transport frame is uneven, the transport frame may tilt. Since the balancing rods rotate synchronously, the rotation speeds of the two balancing rods on the inner side of the rack are kept consistent. At this time, the height of the vertical movement speed of the balancing rods on the inner side of the rack is kept consistent. When the transport frame is driven by a single power source to move vertically up and down, the four sides of the transport frame are ensured to move synchronously, and the transport frame is ensured to move smoothly and be stacked neatly.

[0015] Furthermore, both the transport frame and the support frame are integrated frames to prevent the support frame and the transport frame from being deformed due to the reaction force when stacking the whole board. When the transport frame moves vertically up and down inside the support frame, the positioning slider provided on the transport frame will slide inside the positioning slide groove, and the positioning pulleys provided at both ends of the transport frame will slide outside the four independently distributed support columns provided on the support frame, so that the transport frame and the support frame form a whole, further increasing the structural strength of the transport frame and the support frame as a whole.

[0016] Furthermore, when a wooden board enters the transport frame, the board will first contact the support wheel, so that the board slides on the top of the support wheel into the transport frame. Since the board itself has a certain impact force when entering the transport frame, the two speed reducers will be driven to rotate inside the transport frame during the process of the board entering the transport frame, thereby decelerating the board through the two speed reducers to prevent the board from being damaged due to excessive impact force. At the same time, the second hydraulic rod drives the fixed plate to move toward the inside of the transport frame, so that the second hydraulic rod fixes the board at the bottom of the board stack to prevent the bottom board from being displaced, which causes the entire board stack to be displaced.

[0017] Furthermore, when the plates are stored inside the transport frame, the first hydraulic rod is started to drive the rotating rod to rotate, so that the rotating rod rotates along with the end of the positioning rod until the positioning rod and the plates are fitted together. The fitting of the positioning rod and the plates applies pressure to the side of the plates, thereby limiting the position of the plates inside the transport frame to a certain extent. When the transport frame drives the plates to the next workstation, the transport frame and the plates will rise as a whole inside the support frame to prevent the slight shaking of the equipment from affecting the neat stacking and misalignment of the plates, thereby affecting the subsequent plate processing work.

There are two balance bars 8, and the two balance bars 8 are symmetrically distributed at both ends of the transmission rod 6, and the two ends of the balance bars 8 are fixedly connected with passive bevel teeth 9; the inside of the transport frame 4 is provided with a fixing structure for fixing the plate, the transmission rod 6 is rotatably connected to one side of the top of the transport frame 4, and the two balance bars 8 are rotatably connected to the top of the transport frame 4, and the two ends of the transport frame 4 are fixedly connected with two symmetrically distributed positioning sliders 5, and the positioning sliders 5 are slidably connected to the inside of the positioning slide groove 3, the passive bevel teeth 9 arranged at both ends of the balance bar 8 are meshed with the inner side of the rack 2, and the two The two balancing rods 8 are simultaneously meshed with the two ends of the transmission rod 6, so that the two balancing rods 8 rotate in opposite directions. The four independently distributed support columns provided on the support frame 1 are rotatably connected to the outer sides with positioning pulleys 10, and the positioning pulleys 10 are rotatably connected to the two ends of the transport frame 4. The inside of the transport frame 4 is rotatably connected to two symmetrically distributed speed reducers 11 on both sides, and an elastic rotating shaft is provided at the connection between the speed reducer 11 and the transport frame 4. The outer side of the bottom of the transport frame 4 is rotatably connected to two symmetrically distributed support wheels 12, and the support wheel 12 is composed of two independently distributed pulleys. Four supporting rollers 13 are rotatably connected to the bottom of the transport frame 4, and two supporting rollers 13 are set as a group and symmetrically distributed at the bottom of the transport frame 4. A first hydraulic rod 14 is rotatably connected to one side of the transport frame 4, and a rotating rod 15 is rotatably connected to the end of the first hydraulic rod 14. A positioning rod 16 is fixedly connected to the end of the rotating rod 15, and one end of the rotating rod 15 away from the positioning rod 16 is rotatably connected to the inner side of the bottom of the transport frame 4. Two symmetrically distributed second hydraulic rods 17 are fixedly connected to the bottom of the transport frame 4, and the inner ends of the two second hydraulic rods 17 are fixedly connected to fixed plates 18;

[0027] The transport frame 4 is connected to the equipment that drives it to move up and down, such as a screw rod and a hydraulic rod. When the transport frame 4 moves up and down inside the support frame 1, the transport frame 4 will drive the balance bar 8 to move up and down, so that the balance bar 8 will rotate inside the rack 2 through the passive bevel gear 9 when moving up and down. At the same time, the balance bar 8 is meshed with the transmission rod 6 through the bevel gear ring on its outer side, so that the transmission rod 6 rotates following the rotation of the balance bar 8. Through the connection of the transmission rod 6, the two balance bars 8 can rotate synchronously. Since the balance bar 8 is meshed with the inner side of the rack 2, when the transport frame 4 is unevenly stressed as a whole, the transport frame 4 may tilt. Since the balance bar 8 rotates synchronously, the rotation speed of the two balance bars 8 inside the rack 2 is kept consistent.

[0028] The transport frame 4 and the support frame 1 are both integrated frames to prevent the support frame 1 and the transport frame 4 from being deformed due to the reaction force when stacking the whole board. When the transport frame 4 moves vertically up and down inside the support frame 1, the positioning slider 5 provided on the transport frame 4 will slide inside the positioning slide groove 3, and the positioning pulleys 10 provided at both ends of the transport frame 4 will slide outside the four independently distributed support columns provided on the support frame 1, so that the transport frame 4 and the support frame 1 form a whole, further increasing the structural strength of the transport frame 4 and the support frame 1 as a whole;

[0029] When a wooden board enters the transport frame 4, the board will first contact the support wheel 12, so that the board slides on the top of the support wheel 12 into the transport frame 4. Since the board itself has a certain impact force when entering the transport frame 4, the two deceleration plates 11 will be driven to rotate inside the transport frame 4 during the process of the board entering the transport frame 4, so that the board is decelerated by the two deceleration plates 11 to prevent the board from being damaged due to excessive impact force. At the same time, the second hydraulic rod 17 drives the fixed plate 18 to move toward the inside of the transport frame 4, so that the second hydraulic rod 17 fixes the board at the bottom of the board stack to prevent the bottom board from being displaced, which causes the overall board stack to be displaced.

[0030] When the plates are stored inside the transport frame 4, the first hydraulic rod 14 is started to drive the rotating rod 15 to rotate, so that the rotating rod 15 rotates following the end of the positioning rod 16 until the positioning rod 16 fits the plates. The positioning rod 16 fits the plates and applies pressure to the side of the plates, thereby limiting the plates inside the transport frame 4. When the transport frame 4 drives the plates to the next workstation, the transport frame 4 and the plates will rise as a whole inside the support frame 1 to prevent the slight shaking of the equipment from affecting the neat stacking and misalignment of the plates, thereby affecting the subsequent plate processing work.
