Abstract
Description
Technical Field
[0001] This invention relates to the field of hooklift truck component technology, specifically to a self-loading hooklift truck hooklift assembly. Background Technology
[0002] Hook-lift trucks are indispensable transport vehicles in my country's current sanitation and cleaning work, and are widely used in sanitation waste collection and transportation operations. The hook-lift assembly is an important device for realizing its operational functions, including the underframe, tipping arm, and telescopic arm. When the tipping arm and telescopic arm are locked together, the garbage container can be unloaded; when the tipping arm and telescopic arm are unlocked, the container-pulling and unloading operations of the detachable garbage truck are realized.
[0003] In the operation of a hooklift truck, the hooklift hook is the most important and also the most easily damaged structure. It plays a guiding role in loading and unloading garbage. Traditional hooklift assemblies tilt the garbage container above the assembly by using the tilting arm and the sleeve arm during garbage unloading. This tilts the garbage container and allows the bottom door to open for unloading. Because the garbage container is heavy when loaded, the hooklift hook bears a huge force when tilted, which directly affects its service life. Therefore, existing hooklift assemblies still lack sufficient safety measures for the hooklift hook in actual use, and there is room for improvement in reducing the working load of the hooklift hook and preventing damage to extend its service life. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] I. This invention utilizes the combination of a rack and pinion, a crank-slider assembly, and a threaded block to continuously strike the trash can on the mounting shell by simultaneously displacing it axially and reciprocating vertically relative to the shell. This causes the trash can to vibrate, thereby assisting in the rapid emptying of the internal trash, quickly reducing the load on the hook, and thus maintaining long-term safe use and preventing damage.
[0016] This method, which involves tapping the trash can to assist in emptying the trash, also has the characteristic of moving along the surface of the trash can, thus making the assisted emptying effect better, that is, reducing the load on the assembly hook more quickly.
[0017] Second, the present invention, through the cooperation of structures such as protective plate, transmission rod and displacement groove, can add a rear limit in the rear area of the trash can by extending the protective plate, thereby providing auxiliary support for the trash can, reducing the pressure on the hook and further preventing damage.
[0018] Third, through the cooperation of rod 2, rod 1 and connecting shaft, the present invention can actively compress the stabilizing spring so that after the protective plate moves up and is limited, rod 1 and rod 2 actively apply external force to one side of the protective plate, thereby making the other side of the protective plate stronger in bearing the weight of the garbage can, with stronger safety and stronger structural stability.
[0019] At the same time, after the device returns to its original position, rod one and rod two are retracted to the state shown in the figure, that is, retracted into the installation shell, without affecting the space occupation or the operation of pulling and unloading the trash can.
[0020] Fourth, considering that the garbage furthest from the dumping spout is the first to accumulate in the garbage bin, and therefore remains there for a longer period, making it more difficult to empty due to fermentation and adhesion, this invention reduces the time the garbage bin is tilted, thus reducing the time the hook is under stress. The invention utilizes a combination of toothed blocks, gears, and a discharge spring to allow the striking rod to continuously strike, thereby processing the stubborn garbage at the bottom and quickly emptying it. This further reduces the time the hook is under stress, providing additional protection for the safety of the pull hook. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 13 The present invention provides a self-loading and unloading hook arm assembly, including a main body 1, the main body 1 including a base frame, a tilting arm, a sleeve arm, a cylinder assembly and a locking mechanism, and also including a mounting shell 2 fixedly connected to the tilting arm on the main body 1 and a transmission rod 3 disposed in the mounting shell 2. The top of the mounting shell 2 has four connecting slots and two openings, and a support plate 4 is fixedly connected to the inner wall of the mounting shell 2.
[0038] Vibration rods 5 are provided at both openings. Four striking rods 6 corresponding to the four connecting slots are provided inside the mounting shell 2. A protective plate 7 is slidably connected to the inner wall of the mounting shell 2. A stabilizing plate 8 is provided below the protective plate 7.
[0039] It also includes two sets of discharge components, which drive the two striking rods 6 to move while moving vertically back and forth. It also includes two sets of load protection components, which are connected to the two sets of discharge components to drive the protective plate 7 to move vertically when the striking rods 6 move horizontally. It also includes two sets of cutting components, two sets of auxiliary components and a resistance enhancement component. The auxiliary components are set so that the vibrating rod 5 continues to move vertically back and forth after the striking rods 6 start to move and after they stop moving.
[0040] The discharge components include:
[0041] The threaded rod 9 and two cylinders 10 are rotatably connected to the surface of the support plate 4. The rod wall of the threaded rod 9 is threadedly connected to the sleeve 11.

The end of the transmission rod 3 is fixedly connected to the traveling gear 13. The inner wall of the mounting shell 2 is fixedly connected to the rack 14. The teeth of the traveling gear 13 mesh with the teeth of the rack 14. The two cylinders 10 are slidably connected to the groove walls of the corresponding connecting grooves. The two striking rods 6 are slidably connected to the inner walls of the two cylinders 10. The two striking rods 6 are both connected to the rod wall of the transmission rod 3 through the crank-slider assembly 15.
[0042] Two motors 34 are fixedly connected to the inner wall of the mounting housing 2, and the output ends of the two motors 34 are fixedly connected to the ends of the two threaded rods 9 respectively.
[0043] The cutting component includes a locking block 25. The sleeve 11 has a slot on its side that is compatible with the locking block 25. The locking block 25 is slidably connected to the inner wall of the threaded block 12. A disconnecting spring 26 is fixedly connected to the end of the locking block 25. The end of the disconnecting spring 26 is fixedly connected to the inner wall of the threaded block 12. A disconnecting shaft 27 is fixedly connected to the surface of the locking block 25. A disconnecting plate 28 is slidably connected to the inner wall of the threaded block 12. A disconnecting groove 29 is provided on the surface of the disconnecting plate 28. The groove wall of the disconnecting groove 29 is slidably connected to the shaft wall of the disconnecting shaft 27.
[0044] More specifically, in this embodiment: during use, the device is mounted on a hooklift truck via a base frame. The tilting arm is driven by a control cylinder assembly, which causes the hooks on the tilting arm to pull and unload the garbage bin. When it is necessary to dump the garbage, the tilting arm and the sleeve arm are locked together by a control locking mechanism. At this time, the garbage bin is dumped by driving the cylinder assembly. This process is existing technology, and the relevant structures are mature. Therefore, the specific working principle will not be described in detail.
[0045] During the garbage dumping process, the hook on the tipping arm will bear a large load. In this state, the tipping arm, garbage can, and mounting shell 2 are all tilted. At this time, two motors 34 can be started. Taking one motor 34 as an example, the drive of motor 34 causes the threaded rod 9 to rotate. The rotation of the threaded rod 9 drives the sleeve 11 to rotate. Since the two are threadedly connected, and since in this state, the locking block 25 is inserted into the insertion port on the sleeve 11 under the action of the disengaging spring 26, that is, in this state, the limiting state of the sleeve 11 and the threaded block 12 is consistent. Since the transmission rod 3 passes through the threaded block 12, that is, the threaded block 12... Since the threaded rod 9 cannot rotate around its axis, the motor 34 drives the threaded rod 9 to rotate, which in turn drives the sleeve 11, threaded block 12, transmission rod 3, and internal structures to move axially. This causes the transmission rod 3 to move, which in turn causes the traveling gear 13 to move. Through its interaction with the rack and pinion 14, the transmission rod 3 rotates during this displacement. This rotation of the transmission rod 3, through the transmission of the four crank-slider assemblies 15, causes the four striking rods 6 to move along the inner walls of the four cylinders 10 while moving vertically back and forth. During this process, the four cylinders 10 move synchronously.
[0046] By using four striking rods 6 to continuously strike the trash can on the mounting shell 2 through axial displacement and vertical reciprocating movement, the trash can vibrates, thereby assisting in the rapid emptying of the internal trash, quickly reducing the load on the hook, thus maintaining long-term safe use and preventing damage.
[0047] At the same time, by using this method, the tapping of the trash can assists in the dumping of the trash, and the vibration source also has the characteristic of moving along the surface of the trash can, which makes the auxiliary dumping effect better, that is, reduces the load at the assembly hook more quickly;
[0048] As the sleeve 11 moves, when it is about to approach the support plate 4, the disconnecting plate 28 will first contact the support plate 4. Then, the movement of the sleeve 11 will push the disconnecting plate 28, causing it to slide along the inner wall of the threaded block 12. Through the staggered displacement of the disconnecting plate 28 and the threaded block 12 in this process, the disconnecting shaft 27 slides along the groove wall of the disconnecting groove 29 on the disconnecting plate 28. This causes the locking block 25 to move through the disconnecting shaft 27, compressing the disconnecting spring 26 and causing the locking block 25 to disengage from the insertion port on the side of the sleeve 11. Through the disengagement of the two, the sleeve 11 and the threaded block 12 lose their consistent constraint. At this time, the threaded block 12 contacts the support plate 4 and will no longer move axially. Then, during the rotation of the threaded rod 9, only the sleeve 11 will rotate.
[0049] Example 2, based on the above examples:
[0050] Please see Figures 2 to 10 The load protection component includes: a displacement plate 16, a displacement groove 17 on the surface of the displacement plate 16, the displacement groove 17 including a straight groove and an inclined groove, the rod wall of the transmission rod 3 is slidably connected to the groove wall of the displacement groove 17, the displacement plate 16 is slidably connected to the inner wall of the mounting shell 2, and the surface of the displacement plate 16 is fixedly connected to the bottom surface of the protective plate 7.
[0051] More specifically, in this embodiment: during the axial movement of the transmission rod 3, it will slide along the inclined groove on the displacement groove 17. Through the transmission of the inclined groove, the transmission rod 3 can push the displacement plate 16 to move vertically upward relative to the non-inclined state of the mounting shell 2 after it starts to move. The vertical movement of the displacement plate 16 can drive the protective plate 7 to move vertically, so that the protective plate 7 slides out of the mounting shell 2. During the process of the transmission rod 3 sliding out of the inclined groove on the displacement groove 17 and sliding along the straight groove, the position of the protective plate 7 remains unchanged.
[0052] By extending the protective plate 7, a rear limiter can be added to the rear area of the trash can to provide auxiliary support for the trash can, thereby reducing the pressure on the hook and further preventing damage.
[0053] It is worth noting that during vehicle transport, the connecting hook on the trash can is not tightly fitted with the hook on the assembly, but is located in the middle area of the hook connection. Therefore, the motor 34 can be started when the trash can begins to tilt. That is, when the hook is not under maximum force, the protective plate 7 has already extended a little from the surface of the mounting shell 2, so that when the trash can is tilted, the protective plate 7 can be fully extended. At the same time, the striking rod 6 will not move to the middle area of the trash can, but will just start to move, which does not affect the practical function of assisting in dumping.
[0054] Example 3, based on the above examples:
[0055] Please see Figures 1 to 13The enhanced resistance components include: a connecting shaft 18, with two hinged rods 19 rotatably connected to the shaft wall of the connecting shaft 18. The ends of the two hinged rods 19 are hinged to the side wall of the stabilizing plate 8. Three rods 20 are fixedly connected to the surface of the stabilizing plate 8. Stabilizing springs 21 are fixedly connected to the inner walls of the three rods 20. Rods 22 are fixedly connected to the ends of the three stabilizing springs 21. The three rods 22 are slidably connected to the inner walls of the three rods 20. The ends of the three rods 22 are rotatably connected to the surface of the protective plate 7. The side of the stabilizing plate 8 is connected to the side of the protective plate 7 by three connecting ropes 23. Stabilizing grooves 24 are opened on the surface of the two displacement plates 16. The two sides of the connecting shaft 18 are slidably connected to the groove walls of the two stabilizing grooves 24 respectively. A push plate 35 is fixedly connected to the top surface of the threaded block 12.
[0056] All three connecting ropes 23 are made of non-stretchable material, and the initial angle between the two hinge rods 19 and the three rods 20 is greater than 45°.
[0057] More specifically, in this embodiment: during the upward movement of the protective plate 7, the three rods 22, the three rods 20, the stabilizing plate 8, and the connecting shaft 18 will move upward synchronously. During this process, the relative positions of the rods 22, 20, stabilizing plate 8, and connecting shaft 18 remain unchanged. Meanwhile, during the movement of the threaded block 12, the push plate 35 moves synchronously. At the end of the threaded block 12's movement path, since the protective plate 7 has finished moving upward, the connecting shaft 18 will extend from the support plate 4, exceeding its height. Thus, through the movement of the push plate 35, the connecting shaft 18 is pushed forward. During the movement, the two ends of the connecting shaft 18 slide along the groove walls of the two stabilizing grooves 24 respectively. The movement of the connecting shaft 18 will drive the two hinge rods 19 to move. If there is no connecting rope 23, under the action of the stabilizing spring 21, the first rod 20 and the second rod 22 will not produce relative displacement. That is, the displacement of the two hinge rods 19 will only push the stabilizing plate 8 to deflect, so that the first rod 20 and the second rod 22 deflect towards one side of the protective plate 7, forming a triangular state. However, due to the presence of the connecting rope 23, the stabilizing plate 8 will drive the first rod 20 to actively compress the stabilizing spring 21 during the movement.
[0058] By actively compressing the stabilizing spring 21, after the protective plate 7 moves upward and is stopped, the first rod 20 and the second rod 22 actively apply external force to one side of the protective plate 7, so that the other side of the protective plate 7 has a stronger load-bearing capacity, stronger safety and stronger structural stability when bearing the weight of the garbage can.
[0059] Simultaneously, after the device returns to its original position, rod 20 and rod 22 are retracted to their original positions. Figure 3As shown, the trash can is recycled into the mounting shell 2 without affecting space occupation or the pulling and unloading of the trash can.
[0060] Example 4, based on the above examples:
[0061] Please see Figures 1 to 7 The auxiliary components include: a gear 30, which is fixedly connected to the wall of the threaded rod 9; a limiting rod 31 is fixedly connected to the inner wall of the mounting shell 2; a toothed block 32 is slidably connected to the wall of the limiting rod 31; the teeth of the toothed block 32 mesh with the teeth of the gear 30; a discharge spring 33 is sleeved on the wall of the limiting rod 31; the two ends of the discharge spring 33 are fixedly connected to the surface of the toothed block 32 and the inner wall of the mounting shell 2, respectively; and a vibration rod 5 is fixedly connected to the surface of the toothed block 32.
[0062] More specifically, in this embodiment: during the rotation of the threaded rod 9, the gear 30 will be driven to rotate, thereby pushing the tooth block 32, causing the tooth block 32 to move along the wall of the limiting rod 31 towards the garbage can. When the teeth of the tooth block 32 disengage from the teeth of the gear 30, the tooth block 32 will quickly reset under the elastic action of the discharge spring 33 and re-engage with the teeth of the gear 30. As the gear 30 continues to rotate, the tooth block 32 will quickly move back to its original position along the wall of the limiting rod 31, thereby causing the vibrating rod 5 to quickly move back to its original position, thus continuously striking and vibrating the bottom of the garbage can, the area furthest from the dumping opening. At the same time, as can be seen from the above process, after the striking rod 6 has finished moving, the threaded rod 9 can continue to rotate. Based on this, it can be seen that the vibrating rod 5 can continuously strike and vibrate.
[0063] In this way, considering that the garbage furthest from the dumping spout is the first garbage to accumulate and thus stays in the garbage can for a longer time, making it more difficult to dump out due to fermentation and adhesion, the continuous tapping of the tapping rod 6 during this process can treat the stubborn garbage in the bottom area and make it dumped out quickly. This further reduces the time the hook is under stress and provides auxiliary protection for the safety of the pull hook.
[0064] This method also allows for continuous vibration in the area while other protective structures remain unaffected, thus enhancing its practicality.
[0065] Working principle: When using this self-loading and unloading hooklift truck assembly, the assembly is installed on the hooklift truck via the underframe. The tilting arm is driven by the control cylinder assembly, so that the hook on the tilting arm can pull and unload the garbage bin. When it is necessary to dump the garbage, the tilting arm and the sleeve arm are locked together by the control locking mechanism. At this time, the garbage in the garbage bin is dumped by driving the cylinder assembly.
[0066] During the garbage dumping process, the hooks on the tilting arm will bear a large load. In this state, the tilting arm, garbage can, and mounting shell 2 are all tilted. At this time, by starting the two motors 34, the two threaded rods 9 will rotate, which will cause the four striking rods 6 to move axially and vertically back and forth relative to the mounting shell 2, thereby continuously striking the garbage can and causing it to vibrate. This will help to dump the garbage quickly, reduce the load on the hooks, maintain long-term safe use, and prevent damage. During the axial movement of the transmission rod 3, the protective plate 7 will also move vertically, causing the protective plate 7 to extend and add a rear limit in the rear area of the garbage can, providing auxiliary support for the garbage can and reducing the pressure on the hooks, further preventing damage.
[0067] As the sleeve 11 moves, the support plate 4 pushes the disconnect plate 28, compressing the disconnect spring 26 and causing the locking block 25 to disengage from the insertion port on the side of the sleeve 11. This causes the sleeve 11 and the threaded block 12 to lose their consistency constraint, allowing the threaded rod 9 to continue rotating. Simultaneously, at the end of the movement path of the sleeve 11, the connecting shaft 18 is pushed, and in conjunction with the connecting rope 23, the stabilizing plate 8, during its movement, will cause the rod 20 to actively compress the stabilizing spring 21. By actively compressing the stabilizing spring 21, the protective plate 7 can be stabilized. After the movement is completed and the limit is set, the first rod 20 and the second rod 22 actively apply external force to one side of the protective plate 7, so that the other side of the protective plate 7 has a stronger load-bearing capacity, stronger safety, and stronger structural stability when bearing the weight of the garbage bin. After that, the continued rotation of the threaded rod 9 will cause the toothed block 32 to move back and forth quickly along the rod wall direction of the limit rod 31, thereby processing the stubborn garbage in the bottom area and making it dumped quickly. This further reduces the force time of the hook and provides auxiliary protection for the safety of the hook arm.
