Description

Technical Field

[0001] The invention relates to the field of winch traction, and in particular to a special hoisting machine and a hoisting method for agricultural machinery. Background Art

[0002] With the advancement of science and technology and changes in market demand, the level of agricultural mechanization has made significant progress in recent years, and the application of various large-scale agricultural machinery and equipment has become more and more extensive. In the agricultural production process, the handling and installation of agricultural machinery and equipment is an important but time-consuming and labor-intensive link. Although the existing general lifting machinery can meet some of the needs, their design often fails to fully consider the special structure and weight distribution of agricultural machinery and equipment, resulting in inconvenient operation and prone to safety problems.

[0003] With the advancement of science and technology, technicians in related fields have also optimized the lifting technology used for agricultural machinery and equipment. In order to make a more accurate comparison, a Chinese patent with announcement number CN213771040U discloses an agricultural machinery lifting machine, including a base, a hydraulic rod, an equipment box, a pillar, a telescopic rod, a fixer, a steel rope and a hook mechanism, etc. When in use, the pin column in the hook mechanism is inserted into the column groove to prevent the objects from falling off due to shaking during the lifting process. After the pin column is inserted, such problems are effectively avoided. The rope of the hoisted object is engaged by the buffer groove, and the rubber sleeve is put on to prevent the lifting rope from rubbing back and forth and causing the life of the rope to be accelerated.

[0004] However, when the above-mentioned prior art is used to hoist agricultural machinery, the following problems still exist:

[0005] The above-mentioned prior art fixes the items to be hoisted with a hoisting rope, puts them into the hook and hangs them, then presses the controller down through the movable slot to drive the internal spring to stretch, and after pulling it to a certain position, bends it to the left to disengage the controller from the movable slot and engage it with the wall on the side of the movable slot, and then determines whether the latch column is inserted into the column slot and wraps it to achieve the effect of limiting the hoisting rope and engaging it on the hook. During use, the hoisting equipment is limitedly connected by only a steel rope and a hook. During the process of lifting the equipment, it is necessary to ensure that the connection point of the hoisting rope is at least on the axis of the center of gravity of the equipment to be hoisted. Otherwise, it is easy for the equipment to deflect and shake significantly after being lifted, which may lead to safety problems.

[0006] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing technical means for lifting agricultural machinery. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a special lifting machine for agricultural machinery equipment, including a base and a support arm, and a winch assembly for lifting the equipment is connected to the support arm.

[0008] The described hoisting assembly includes:

[0009] A winding drum, which is limitedly connected to one side of the support arm close to the base, and a hoisting rope is wound thereon for hoisting.

[0010] A pulley, which is limited to the side of the support arm away from the winding drum, and the hoisting rope is driven by the winding drum to slide and adjust along the pulley.

[0011] An adjusting end, which is limited to the side of the hoisting rope away from the winding drum, and is used for adjusting and limiting the hoisting rope released from the winding drum, so that the hoisting rope is limited to multiple segments for hoisting agricultural machinery equipment.

[0012] Preferably, the adjusting end includes a plurality of limiting sleeves sleeved on the hoisting rope, and a support chassis for limiting and supporting the limiting sleeves is commonly connected between the plurality of limiting sleeves.

[0013] Preferably, the hoisting rope is in a double-strand shape and is limitedly inserted into the limiting sleeve and slides out of the limiting sleeve.

[0014] Preferably, the hoisting rope released from the winding drum is sequentially inserted into a plurality of limiting sleeves, and then passes through the last limiting sleeve and is connected to the support arm.

[0015] Preferably, the adjusting end further includes an adjusting rotating rod inserted through the middle of the support chassis. A limiting support plate for limiting and guiding the sliding path of all the limiting sleeves is connected to the adjusting rotating rod. A driving gear is sleeved on the adjusting rotating rod, and a plurality of driven tooth plates corresponding to the limiting sleeves are meshed outside the driving gear. The driven tooth plates and the limiting sleeves are connected through connecting guide blocks.

[0016] Preferably, a plurality of pulleys corresponding to the plurality of limiting sleeves are provided, and the plurality of pulleys and the limiting sleeves are circumferentially and evenly distributed around the axis of the support chassis.

[0017] Preferably, an installation frame is connected to the limiting support plate, and limiting rollers are symmetrically limited on the installation frame for supporting and limiting the hoisting rope between adjacent two limiting sleeves.

[0018] Preferably, the limiting sleeve is arranged in a bent shape, and a guiding sliding block inserted through the support chassis is connected to the limiting sleeve.

[0019] Preferably, a plurality of guiding through grooves corresponding to the plurality of limiting sleeves are formed on the limiting support plate, so as to limit and guide the sliding path of the limiting sleeves.

[0020] In addition, the present invention also provides a special hoisting method for agricultural machinery equipment, including the following steps:

[0021] S1: Adjust the length and height of the support arm by sliding to meet the lifting requirements at different heights. Then, adjust the relative position between the hoisting assembly and the equipment to be hoisted, and limit and connect the agricultural machinery equipment to be hoisted to the loop of the hoisting rope in the hoisting assembly to ensure a firm connection.

[0022] S2: After driving the hoisting rope to form multiple groups of loops in several limiting sleeves, control the relative position between all the limiting sleeves through the adjusting end to adjust the position of the hoisting rope passing through the limiting sleeves, so that the relative positions of the loops are evenly distributed, realizing multi-point hoisting of the agricultural machinery equipment and ensuring the stable operation of the hoisting process.

[0023] S3: Start the hoisting assembly and control the lifting of the equipment by winding or releasing the hoisting rope to drive the agricultural machinery equipment limited on several loops to adjust its height.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] First, by driving the hoisting rope to sequentially pass through and slide at several circumferentially distributed limiting sleeves, the hoisting rope forms loops at the limiting sleeves. Through the uniform distribution of multiple segments of loops, multi-point limiting hoisting of the agricultural machinery equipment is realized, effectively increasing the hoisting stability and avoiding the shaking and deflection of the equipment.

[0026] Second, by adjusting the cooperation between the rotating rod, the driving gear and several corresponding driven toothed plates and limiting sleeves, synchronous adjustment of multiple segments of hoisting rope loops sliding through the limiting sleeves is realized, so that the loops formed by the hoisting rope at the limiting sleeves adapt to the specifications of the agricultural machinery equipment to be hoisted, thus ensuring that the equipment always remains in the middle position during the hoisting process and avoiding the problem of large shaking.

[0027] Third, through the corresponding cooperation between several adjusting sleeves, limiting sleeves and adjusting springs, the position of the loop can be adaptively adjusted according to the state of the equipment after hoisting during the hoisting process, automatically adjusting the position of the loop to ensure that the equipment is always in a balanced state and further improving the hoisting stability.

Specific embodiments

[0038] The following combines the attached Figure 1 To the attached Figure 8 The embodiments of the present invention will be described in detail.

[0039] The embodiments of the present application disclose a special hoisting machine and method for agricultural machinery equipment. It should be noted that the present application is mainly applied in the process of hoisting agricultural machinery equipment, and achieves the effect of hoisting agricultural machinery equipment in terms of technical effects; especially in the hoisting process, through the cooperation between the lifting rope and several limit sleeves, the effect of synchronously hoisting the equipment to be hoisted at multiple points is achieved; and, the present application also adaptively adjusts the position of the rope loop according to the state of the equipment after hoisting through the corresponding cooperation between several adjusting sleeves, limit sleeves and adjusting springs during the hoisting process, ensuring that the equipment is always in a balanced state and further improving the hoisting stability.

[0040] Embodiment 1: Refer to Figure 1As shown, a special lifting machine for agricultural machinery equipment includes a base 1 and a support arm 10, and a winch assembly 2 for lifting equipment is connected to the support arm 10. It should be noted that the support arm 10 is a telescopic support arm that allows extension and retraction, and a hydraulic rod is also obliquely connected between the base 1 and the support arm 10 for supporting the limit. When in use, adjust the support arm 10 to perform telescopic sliding, and at the same time adjust the relative position between the winch assembly 2 and the equipment to be lifted, and then connect the equipment to be lifted to the winch assembly 2, and start the winch assembly 2 to drive the limited equipment to be raised and lowered, so as to achieve the effect of lifting it.

[0041] Reference Figure 2 and Figure 3 As shown, the hoisting assembly 2 is used for hoisting equipment; specifically, the hoisting assembly 2 includes:

[0042] The winding drum 20 is limit-connected to a side of the supporting arm 10 close to the base 1, and a hoisting rope 21 is wound around the winding drum for hoisting.

[0043] The pulley 22 is limited at a side of the support arm 10 away from the winding drum 20 , and the hoisting rope 21 is driven by the winding drum 20 to slide and adjust along the pulley 22 .

[0044] The adjusting end 23 is limited on the side of the lifting rope 21 away from the winding drum 20, and is used to adjust and limit the lifting rope 21 after being released from the winding drum 20, so that the lifting rope 21 is limited to multiple sections for lifting agricultural machinery.

[0045] Reference Figures 3 to 5 As shown, the adjustment end 23 includes a plurality of limiting sleeves 230 which are limitedly sleeved on the hoisting rope 21, and a support chassis 231 for limiting and supporting the limiting sleeves 230 is commonly connected between the plurality of limiting sleeves 230. When in use, the hoisting rope 21 is driven to pass through the plurality of limiting sleeves 230, and the length of the hoisting rope 21 after release is limitedly adjusted by the plurality of limiting sleeves 230, so as to be applicable to equipment to be hoisted of different specifications.

[0046] Reference Figures 3 to 6 As shown, the lifting rope 21 is in a double-stranded shape and is limitedly inserted into the limiting sleeve 230 and slides out of the limiting sleeve 230. After the double-strand lifting rope 21 passes through the limiting sleeve 230, a rope loop 210 is formed on one side of the limiting sleeve 230, thereby facilitating the subsequent limited lifting of the agricultural machinery that needs to be lifted.

[0047] Further, refer to Figures 3 to 6As shown, the hoisting rope 21 released on the winding drum 20 is successively passed through a number of limiting sleeves 230, and then passes through the last limiting sleeve 230 and is connected to the support arm 10. That is, one end of the hoisting rope 21 on the winding drum 20 passes through a number of limiting sleeves 230 in sequence and is connected to the support arm 10. During use, when the winding drum 20 is driven to rotate to wind or release the hoisting rope 21, during the process of increasing or decreasing the length of the hoisting rope 21, a number of limiting sleeves 230 through which the hoisting rope 21 passes are driven to slide and adjust, so as to realize the adjustment of the relative position between the limiting sleeve 230 and the hoisting rope 21, that is, the effect of lifting and lowering the position height of the limiting sleeve 230 and the support chassis 231.

[0048] Referring Figures 3 to 6 As shown, the adjusting end 23 further includes an adjusting rotating rod 232 passing through the middle of the support chassis 231. A limiting support plate 233 for limiting and guiding the sliding path of all the limiting sleeves 230 is connected to the adjusting rotating rod 232. A driving gear 234 is sleeved on the adjusting rotating rod 232. A number of driven toothed plates 235 corresponding to the limiting sleeves 230 are meshed on the outside of the driving gear 234. The driven toothed plates 235 and the limiting sleeves 230 are connected through connecting guide blocks 236.

[0049] During use, after the rope loop 210 formed by passing the hoisting rope 21 through the limiting sleeve 230 is limit-connected to the agricultural machinery equipment, the adjusting rotating rod 232 is driven to rotate through the prior art such as a driving motor. After the adjusting rotating rod 232 rotates, it drives the driving gear 234 to rotate. After the driving gear 234 rotates, it drives the driven toothed plates 235 meshed with it to slide. The sliding of the driven toothed plates 235 drives the connected connecting guide blocks 236 and the limiting sleeves 230 to slide and adjust. The sliding of the limiting sleeves 230 drives one section of the hoisting rope 21 passing through the limiting sleeves 230 to slide and adjust. By driving the synchronous sliding between all the limiting sleeves 230, the synchronous adjustment effect of the position of the rope loop 210 of the hoisting rope 21 at the limiting sleeves 230 is driven, so that after the agricultural machinery equipment is limit-hoisted through the rope loop 210 of the hoisting rope 21, the hoisted agricultural machinery equipment is always kept in the middle of all the rope loops 210 of the hoisting ropes 21, thus effectively avoiding the problem that the agricultural machinery equipment is prone to deflection and shaking after being hoisted.

[0050] It should be noted that in order to drive all the driven toothed plates 235 to perform synchronous sliding adjustment through the driving gear 234, two adjacent driven toothed plates 235 are distributed in an upper and lower stacked manner. At the same time, the position heights of two parallel and corresponding driven toothed plates 235 are the same. All the driven toothed plates 235 are circumferentially distributed with the axis of the driving gear 234 as the axis.

[0051] In order to facilitate the limitation and guidance of the sliding path of the driven tooth plate 235, a number of sliding seats 237 are correspondingly arranged on the support chassis 231 for a number of driven tooth plates 235.

[0052] Referring to Figures 4 to 7 As shown, a plurality of pulleys 22 are correspondingly arranged for a number of limiting sleeves 230. A number of pulleys 22 and limiting sleeves 230 are circumferentially and uniformly distributed around the axis of the support chassis 231. One end of the lifting rope 21 far from the connected receiving reel 20 sequentially slides through all the pulleys 22 and limiting sleeves 230 and is then limited and separated into a number of rope loops 210. A number of rope loops 210 are circumferentially distributed at the support chassis 231 corresponding to a number of limiting sleeves 230, thereby realizing the effect of hoisting the agricultural machinery equipment at multiple points and effectively increasing the stability during the hoisting of the equipment.

[0053] Referring to Figure 5 and Figure 6 As shown, an installation frame 24 is connected to the limiting support plate 233. Limiting rollers 240 are symmetrically limited on the installation frame 24 and are used to support and limit the lifting rope 21 between adjacent two limiting sleeves 230. During use, the limiting rollers 240 limit and guide the lifting rope 21 sliding through between a number of limiting sleeves 230, and significantly reduce the friction between the lifting rope 21 and the limiting sleeves 230 through the rotation of the limiting rollers 240, improving the sliding adjustment efficiency of the lifting rope 21 between a number of limiting sleeves 230.

[0054] Referring to Figure 5 and Figure 6 As shown, the limiting sleeve 230 is arranged in a bent shape, and a guiding slider 25 penetrating through the support chassis 231 is connected to the limiting sleeve 230.

[0055] Referring to Figure 5 and Figure 6 As shown, a number of guiding through grooves 250 are formed on the limiting support plate 233 corresponding to a number of limiting sleeves 230, so as to limit and guide the sliding path of the limiting sleeves 230.

[0056] Embodiment 2: Referring to Figures 5 to 8 As shown, on the basis of Embodiment 1, during the process of hoisting and lifting the agricultural machinery equipment, since the size specifications of different agricultural machinery equipment are different, when the agricultural machinery equipment to be hoisted is limited and connected to the rope loops 210 on a number of lifting ropes 21, it is very likely that the initial height positions of the connections on the agricultural machinery equipment are different. Therefore, during the hoisting process through a number of circumferentially distributed rope loops 210, the equipment to be hoisted is very likely to be in an overall skewed state, resulting in continuous deflection of the equipment during the hoisting and lifting process due to the overall skew, increasing the friction between the equipment and the lifting rope 21, leading to an increase in the loss of the lifting rope 21 and prone to safety problems.

[0057] Based on the above, in order to avoid the problem of easy shaking during the hoisting of the equipment, an adjusting sleeve 26 is slidably penetrated in the bent section of the limit sleeve 230, and the loop 210 of the hoisting rope 21 also slidably passes through the adjusting sleeve 26. A driven slider 260 is connected to the adjusting sleeve 26, and an adjusting spring 261 is commonly connected between the sliding seat 237 and the driven slider 260.

[0058] In the initial state, the adjusting spring 261 is in a normal extended state, so as to drive the connected driven slider 260 and adjusting sleeve 26 to slide, so that the adjusting sleeve 26 protrudes from the connected limit sleeve 230. After the agricultural machinery equipment is limited and connected to the loop 210 of the hoisting rope 21 protruding outside the limit sleeve 230 and the adjusting sleeve 26, at this time, after several loops 210 are connected to different parts of the agricultural machinery equipment, during the process of driving the agricultural machinery equipment to lift and lower, the hoisting rope 21 is wound up so that several loops 210 are tightened. At this time, the tightened loop 210 will exert a pressure on the connected adjusting sleeve 26 in a direction towards the middle driving gear 234, so that the adjusting spring 261 is compressed by the force. At this time, because the adjusting spring 261 is compressed by the force, the driven slider 260 and the adjusting sleeve 26 connected to the adjusting spring 261 have a tendency to always slide in a direction away from the middle driving gear 234. That is, the elastic restoring force of the adjusting spring 261 and the pressure exerted on the adjusting sleeve 26 by the hoisting rope 21 form an opposing effect.

[0059] During the hoisting of the agricultural machinery equipment, if the hoisted agricultural machinery equipment is skewed during the hoisting process, that is, when one side of the agricultural machinery equipment is higher and the other side is lower after being hoisted, at this time, it will cause the pressures exerted on the connected adjusting sleeve 26 by the two corresponding loops 210 on the support chassis 231 to change accordingly. Specifically, the pressure exerted on the adjusting sleeve 26 by the higher side after hoisting is weakened. At this time, driven by the connected adjusting spring 261, the adjusting sleeve 26 is driven to further slide in a direction away from the driving gear 234, while the pressure exerted on the adjusting sleeve 26 by the loop 210 on the lower side of the other side of the hoisting will further increase. At this time, the adjusting sleeve 26 will further slide in a direction towards the driving gear 234 and drive the connected adjusting spring 261 to be further compressed. Through the mutual cooperation between several loops 210 and the corresponding adjusting sleeve 26 and adjusting spring 261, the relative position between the adjusting sleeve 26 and the corresponding limit sleeve 230 is adjusted, that is, the corresponding adjustment effect of the force arm between the loop 210, the limit sleeve 230 and the agricultural machinery equipment is achieved, so that the agricultural machinery equipment always remains at the middle position of all the loops 210, and the hoisting position of the agricultural machinery during the hoisting process is adaptively adjusted to improve the stability during the hoisting process.

[0060] In addition, the present invention also provides a special hoisting method for agricultural machinery equipment, which includes the following steps:

[0061] S1: Adjust the length and height of the support arm 10 through sliding to meet the hoisting requirements at different heights. Then, adjust the relative position between the winch assembly 2 and the equipment to be hoisted, and limit and connect the agricultural machinery equipment to be hoisted to the loop 210 of the hoisting rope 21 in the winch assembly 2 to ensure a firm connection.

[0062] S2: After driving the hoisting rope 21 to form multiple groups of loops 210 within a number of limiting sleeves 230, adjust the relative position between all the limiting sleeves 230 through the adjusting end 23 to adjust the position of the hoisting rope 21 passing through the limiting sleeves 230, so that the relative positions of the loops 210 are evenly distributed, realizing multi-point hoisting of the agricultural machinery equipment and ensuring the stable operation of the hoisting process.

[0063] S3: Start the winch assembly 2 and control the lifting of the equipment by winding or releasing the hoisting rope 21 to drive the agricultural machinery equipment limited to a number of loops 210 to adjust the height.

[0064] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

[0065] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
