Description

Technical Field

[0001] The utility model relates to the technical field of tipping frame design, in particular to a new type of tipping frame for a transport forklift that is convenient to turn over. Background Art

[0002] The forklift tipping frame is an important accessory of the forklift, mainly used to improve the loading and unloading efficiency of goods, and has a wide range of applications in industries such as logistics, construction, and manufacturing. Especially in scenarios where bulk materials, metallurgical slag, cement, etc. are loaded and unloaded, the application of the forklift tipping frame is particularly extensive. In addition, with the rapid development of fields such as agriculture and environmental protection, the application of the forklift tipping frame in these fields is also gradually increasing.

[0003] When the existing forklift tipping frame is in use, in order to prevent the transported garbage or goods from falling, most of them are equipped with hinged lids. However, when these lids are in use, they often need to be manually opened and closed, which is very inconvenient. Therefore, some improved tipping frames are equipped with a mechanism for opening the flip cover. For example, a forklift handling tipping bucket disclosed in Application No. 202121041029.6 drives the first gear to rotate through a motor, the first gear drives the chain to transmit, so that the fixed block on the chain moves, drives the vertical rod to move, and the vertical rod drives the protective cover to open and close, which is convenient to use.

[0004] The above solution solves the inconvenience of manually closing the flip cover to a certain extent. However, after actual investigation, it is found that there are still certain deficiencies. First of all, the driving mechanism is arranged on both sides of the tipping bucket, which makes the space limited during loading, and it can only be filled from the front of the tipping bucket, which is very inconvenient. At the same time, the angle of rotation of the flip cover driven by the lifting of the vertical rod is limited, and the opening angle of the flip cover is not large, which also easily causes certain inconveniences during loading. For example, it is easy to get the loaded goods on the lid or spill, etc., and it is also easy to block during dumping.

[0005] Therefore, the applicant proposes a new type of tipping frame for a transport forklift that is convenient to turn over to solve the problem. Summary of the Utility Model

[0006] The utility model provides a new type of tipping frame for a transport forklift that is convenient to turn over, and solves the problems raised in the above background.

[0007] To solve the above technical problems, a novel tipping bucket frame for a transport forklift that is easy to tip over provided by the utility model includes a tipping bucket frame. A first shaft rod is rotatably connected between two first support blocks fixed on one side of the tipping bucket frame. An L-shaped shaft block is fixedly connected to the first shaft rod. A cover plate is fixed on one side of the L-shaped shaft block. A pull rope is tied to a round rod fixed on the top of the cover plate. The other end of the pull rope is wound around a reel. The reel is installed on the top of a first support plate. A motor for driving the reel to wind and unwind is installed on the top of the first support plate, and the first support plate is fixed on the side wall of the tipping bucket frame. A second support plate is installed on the side wall of the tipping bucket frame above the first support plate. Two abutting blocks are symmetrically installed at the top end of the second support plate. The top surface of the abutting block is designed as an inclined surface and can fit with the side wall of the L-shaped shaft block. A tipping plate is installed on the first shaft rod. The tipping plate can be docked with a reset mechanism installed on the top of the second support plate.

[0008] Preferably, a layer of soft pad is adhered to the top surface of the abutting block, and the soft pad is made of corrosion-resistant rubber.

[0009] Preferably, when one side of the L-shaped shaft block fits with the inclined surface at the top of the abutting block, the rotation angle of the L-shaped shaft block is 75 degrees.

[0010] Preferably, a guide pulley A is fixed on the side wall of the second support plate, and a guide pulley B is installed on the top surface of the end of the cover plate close to the L-shaped shaft block. The pull rope moves on the surfaces of the guide pulley A and the guide pulley B.

[0011] Preferably, the pull rope is made of nylon material, and a layer of corrosion-resistant paint is coated on the surface of the pull rope.

[0012] Preferably, the reset mechanism includes two second support blocks fixed on the top of the second support plate. A second shaft rod is rotatably installed between the two second support blocks and the two abutting blocks respectively. A reset block is fixed on the second shaft rod. A spring is connected between the bottom surface of one end of the reset block and the top of the second support plate. The other end of the reset block rotates downward by contacting the rotating tipping plate when the cover plate is opened, and at this time the spring is stretched upward.

[0013] Preferably, a limiting rod is fixed between the abutting blocks. The limiting rod is located on one side of the spring, and the limiting rod fits with the bottom surface of the reset block when the reset block is in the initial state.

[0014] Compared with the related art, a novel tipping bucket frame for a transport forklift that is easy to tip over provided by the utility model has the following beneficial effects:

[0015] The utility model designs a first shaft rod, an L-shaped shaft block, a round rod, a pull rope, a winding drum, a motor and a blocking block. When working, the motor at the top of the first support plate is started to wind the pull rope, so as to pull the round rod and drive the cover plate to rotate, and the cover plate is opened. At the same time, one side of the L-shaped shaft block fits with the inclined surface at the top of the blocking block, completing the automatic opening operation of the cover plate. The first support block, the first support plate and the second support plate are all arranged on the back of the tipping bucket frame, thus not affecting the staff's loading at both sides of the tipping bucket frame. And through the pulling of the pull rope, the rotation angle of the cover plate and the L-shaped shaft block can reach 75 degrees, making the opening angle of the cover plate very large, which is more convenient during filling or tipping and pouring.

[0016] The utility model designs a reset mechanism. When it is necessary to close the cover plate, the winding drum unwinds at a uniform and slow speed. One end of the reset block loses pressure, and the spring pulls the tilted end of the reset block, so that the other end of the reset block applies an upward push to the turning plate. The turning plate can drive the L-shaped shaft block on the first shaft rod to rotate, driving the cover plate to reset as the winding drum unwinds. This effectively improves the stability of the cover plate closing and avoids the situation where the cover plate cannot be closed. Description of the Drawings

Detailed implementation mode

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] As shown by Figures 1-6 The present invention provides a novel tipping frame for a transport forklift that is easy to tip, including a tipping frame 1. A first shaft 4 is rotatably connected between two first support blocks 3 fixed to one side of the tipping frame 1. An L-shaped shaft block 5 is fixedly connected to the first shaft 4. A cover plate 2 is fixed to one side of the L-shaped shaft block 5. A pull rope 7 is tied to a round rod 6 fixed to the top of the cover plate 2. The other end of the pull rope 7 is wound around a reel 9. The reel 9 is installed on the top of a first support plate 8. A motor 10 for driving the winding and unwinding of the reel 9 is installed on the top of the first support plate 8. And the first support plate 8 is fixed to the side wall of the tipping frame 1. A second support plate 11 is installed above the first support plate 8 on the side wall of the tipping frame 1. Two abutting blocks 12 are symmetrically installed at the top of the second support plate 11. The top surface of the abutting block 12 is designed as an inclined surface and can be attached to the side wall of the L-shaped shaft block 5. A turning plate 16 is installed on the first shaft. The turning plate 16 can be docked with a reset mechanism 17 installed on the top of the second support plate 11. When one side of the L-shaped shaft block 5 is attached to the inclined surface at the top of the abutting block 12, the rotation angle of the L-shaped shaft block 5 is 75 degrees.

[0026] By designing the first shaft rod 4, L-shaped shaft block 5, round rod 6, pull rope 7, reel 9, motor 10 and abutting block 12, during operation, the tipping frame 1 is installed at a suitable position on the forklift through the connecting plate at its bottom. At this time, the cover plate 2 is in contact with the tipping frame 1 and in a closed state. When it is necessary to load and open the cover plate 2, start the motor 10 at the top of the first support plate 8. The reel 9 is rotatably connected between two support plates at the top of the first support plate 8, and the motor shaft of the motor 10 is docked with the rotating shaft of the reel 9, so that the motor 10 drives the reel 9 to rotate, winds the pull rope 7, and the pull rope 7 can pull the round rod 6 and drive the cover plate 2, L-shaped shaft block 5 and the first shaft rod 4 to rotate between the first support blocks 3, opening the cover plate 2. Finally, one side of the L-shaped shaft block 5 is in contact with the inclined surface at the top of the abutting block 12, completing the automatic opening operation of the cover plate, and at this time, the L-shaped shaft block 5 is in a stable state, so that the cover plate 2 will not become loose when the tipping frame 1 is tilted. In this way, the first support block 3, the first support plate 8 and the second support plate 11 are all arranged on the back of the tipping frame 1, and thus will not affect the staff to load at both sides of the tipping frame 1. And through the pulling of the pull rope 7, the cover plate 2 and the L-shaped shaft block 5 can rotate up to 75 degrees, making the opening angle of the cover plate 2 very large, which is more convenient during filling or tipping, and is very practical. It should be noted that in this case, the tipping drive point of the tipping frame 1 is at the bottom, so the various drive components installed on its back do not affect its operation.

[0027] A layer of soft pad 13 is bonded to the top surface of the abutting block 12, and the soft pad 13 is made of corrosion-resistant rubber.

[0028] In this way, when the abutting block 12 abuts against the L-shaped shaft block 5, in order to keep the positions of the L-shaped shaft block 5 and the cover plate 2 stable, it is necessary to tighten the cover plate 2 with the pull rope 7. Therefore, the acting force between the abutting block 12 and the L-shaped shaft block 5 is relatively large. At this time, the soft pad 13 can prevent the two from directly contacting, avoiding wear caused by excessive pressure and playing a good protective role.

[0029] A guide pulley A15 is fixed on the side wall of the second support plate 11, and a guide pulley B14 is installed on the top surface of the end of the cover plate 2 close to the L-shaped shaft block 5. The pull rope 7 moves on the surfaces of the guide pulley A15 and the guide pulley B14.

[0030] In this way, the guide pulley A15 and the guide pulley B14 can effectively support the pull rope 7. On the one hand, it makes the operation of the pull rope 7 more stable. On the other hand, it avoids the pull rope 7 directly contacting with components such as the reset mechanism 17 or the second support plate 11 and causing wear, playing a good guiding and protective role.

[0031] The pull rope 7 is made of nylon material, and a layer of corrosion-resistant paint is coated on the surface of the pull rope 7.

[0032] Since the tipping bucket frame 1 often works in an environment with dust or high humidity, the pulling rope 7 is made of nylon and painted on one side, so that its own quality and strength are very good and it can be used for a long time without replacement.

[0033] The reset mechanism 17 includes two second support blocks 1701 fixed to the top of the second support plate 11. Rotating shafts 1702 are installed between the two second support blocks 1701 and the two abutting blocks 12 respectively. A reset block 1703 is fixed on the rotating shaft 1702. One end of the bottom surface of the reset block 1703 is connected to the top of the second support plate 11 by a spring 1704. The other end of the reset block 1703 rotates downward by contacting the rotating turnover plate 16 when the cover plate 2 is opened, and at this time the spring 1704 is stretched upward.

[0034] Although the cover plate 2 does not rotate upward to 90 degrees, the pulling rope 7 still pauses or cannot be closed due to the arc of the cover plate 2 during the unwinding of the pulling rope 7, causing the pulling rope 7 to become disordered. Therefore, by designing the reset mechanism 17, during the opening process of the cover plate 2, the turnover plate 16 rotates together with the first shaft 4, and then contacts the top of one end of the reset block 1703 and pushes it downward. Through the pressure, the reset block 1703 rotates around the rotating shaft 1702 between the abutting block 12 and the second support block 1701, and the other end stretches the spring 1704. Then when the cover plate 2 needs to be closed, the winding drum 9 unwinds evenly and slowly. One end of the reset block 1703 loses the pressure, and the spring 1704 pulls the upturned end of the reset block 1703, so that the other end of the reset block 1703 applies an upward push to the turnover plate 16. The turnover plate 16 can drive the L-shaped shaft block 5 on the first shaft 4 to rotate, driving the cover plate 2 to reset as the winding drum 9 unwinds. This effectively improves the stability of the closing of the cover plate 2 and avoids the situation where the cover plate 2 cannot be closed.

[0035] Furthermore, a limiting rod 1705 is fixed between the abutting blocks 12. The limiting rod 1705 is located on one side of the spring 1704, and the limiting rod 1705 is in contact with the bottom surface of the reset block 1703 when the reset block 1703 is in the initial state.

[0036] In this way, when the reset block 1703 is in the initial state, the limiting rod 1705 prevents the end of the reset block 1703 close to the spring 1704 from rotating downward, keeping it in a relatively stable state.
