Description

Technical Field

[0001] The utility model relates to the technical field of transport forklifts, and specifically relates to an anti-rollover transport forklift. Background Art

[0002] A manual forklift, as a two-purpose vehicle for high-lift loading and unloading and short-distance transportation, plays an important role in the fields of logistics transportation, warehousing management, and manufacturing due to its unique advantages and wide application scenarios. The working principle of a manual forklift mainly relies on human power and a hydraulic system. The hydraulic oil is pumped into the lifting cylinder through a hydraulic pump, thereby pushing the fork on the fork arm upward. When it is necessary to lower the fork, the hydraulic oil is released back into the fuel tank through a control lever, and the fork will slowly descend. The direction controller is used to control the steering of the wheels to change the driving direction.

[0003] Since the dimensions of a manual forklift are usually smaller on the left and right sides than on the front and back sides, and the objects stacked on it during transportation may be relatively tall, and the weight of the forklift itself is limited, when the upper cargo slips sideways, or when the forklift turns, due to the relatively long lever arm, the forklift will be subjected to a large bending moment, resulting in rollover or even overturning, which brings inconvenience to the transportation work and is more likely to cause the transported objects to be damaged. Therefore, in view of the above problems, an anti-rollover transport forklift is proposed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an anti-rollover transport forklift. When transporting objects stacked relatively high, the transport forklift can push the end of the diagonal brace to move through a screw angle adjustment mechanism, and then push the anti-tipping brace to expand through the diagonal brace. When the forklift rolls over, the anti-tipping brace can cooperate with the end auxiliary support mechanism at its end to play a supporting role, preventing the forklift from tilting further, facilitating the operator to adjust the position of the object and right the forklift, being able to avoid damage to the object caused by the overturning of the forklift, and when the height of the transported object is not high, the anti-tipping brace can be in a retracted state through the screw angle adjustment mechanism, avoiding the influence of the outward extension of the anti-tipping brace on the use of the forklift, and solving the technical problem that in the prior art, the forklift is prone to rollover or even overturning when transporting relatively high objects or when the forklift makes a large turn, which brings inconvenience to the transportation work.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is as follows:

[0006] An anti-rollover transport forklift includes a manual hydraulic forklift body, with outer extension connecting plates fixedly arranged on both sides thereof, an anti-tipping brace, which is rotatably connected to the outer extension connecting plate and plays a lateral supporting role, and a diagonal brace is rotatably connected to the middle thereof, a screw angle adjustment mechanism, which is used to drive the end of the diagonal brace away from the anti-tipping brace to move back and forth, thereby driving the anti-tipping brace to rotate, and an end auxiliary support mechanism, which is rotatably arranged at the outer end of the anti-tipping brace.

[0007] With the above-mentioned structural form, when transporting objects stacked high, the screw rod angle adjustment mechanism can be used to push the end of the diagonal brace to move, and then the diagonal brace can be used to push the anti-roll brace to unfold it. When the forklift tilts, the anti-roll brace can be combined with the end auxiliary support mechanism at its end to play a supporting role, preventing the forklift from further tilting, making it convenient for the operator to adjust the position of the object and straighten the forklift, which can avoid damage to the object caused by the overturning of the forklift. When the height of the transported object is not high, the screw rod angle adjustment mechanism can be used to make the anti-roll brace in a retracted state, avoiding the anti-roll brace from extending outward and affecting the use of the forklift.

[0008] In a possible implementation, the screw angle adjustment mechanism includes a guide rail housing, in which a slide is slidably arranged, and the slide is rotatably connected to the end of the diagonal support through a third rotating connection member.

[0009] Through the above-mentioned structural form, the sliding of the slide table can drive the end of the diagonal brace to move, and then the diagonal brace can drive the anti-roll support rod to expand or retract.

[0010] In a possible implementation, a transmission screw that is threadably connected to the slide is rotatably disposed in the guide rail housing, and a handwheel is fixedly connected to the outer end of the transmission screw.

[0011] Through the above-mentioned structural form, the operator can drive the transmission screw with a handwheel, and then drive the slide to slide back and forth through the threaded engagement, and this type of drive form has a self-locking effect, that is, when the transmission screw does not rotate, the slide cannot be displaced, so that it has the effect of fixing the position of the anti-roll support rod.

[0012] In a possible implementation, a hinged plate is fixedly provided at the middle portion of the anti-roll support rod, and is rotatably connected to the end portion of the diagonal support rod via a second rotatable connection member.

[0013] The above-mentioned structural form provides the necessary structural basis for the rotational connection between the diagonal brace and the anti-roll brace rod.

[0014] In a possible implementation, the end auxiliary support mechanism includes an auxiliary support rod, which is rotatably connected to the anti-roll support rod through a threaded rotating rod, and the end of the auxiliary support rod is processed with a rounded corner. A locking nut is threadedly connected to the threaded rotating rod.

[0015] Through the above-mentioned structural form, the contact area between the end of the anti-roll strut and the ground can be increased by the auxiliary strut, thereby achieving a better anti-roll effect. At the same time, the auxiliary strut is rotatably connected to the anti-roll strut, which can be convenient for folding and storing, and the locking nut can fix the auxiliary strut so that it cannot rotate when subjected to force, thereby ensuring the role of force transmission.

[0016] In a possible implementation, a square clamping block is fixedly arranged at the bottom of the threaded rotating rod, and a square cylinder with a size matching that of the square clamping block is fixedly arranged at the end of the anti-tilting support rod. When the square clamping block just leaves the square cylinder, the auxiliary support rod does not contact the ground.

[0017] With the above structural form, when the locking nut is tightened, the square clamping block cannot be disengaged from the square cylinder. At this time, the auxiliary support rod cannot rotate, ensuring the force transmission function. When the locking nut is loosened, the square clamping block can be disengaged from the square cylinder, and at this time, the auxiliary support rod can rotate and fold up.

[0018] In a possible implementation, the extended connecting plate is rotatably connected to the end of the anti-tilting support rod through a first rotating connecting piece. Two symmetrically arranged reinforcing ribs are fixedly arranged on the upper end surface of the extended connecting plate, and the ends of the reinforcing ribs are welded to the manual hydraulic forklift body.

[0019] With the above structural form, it provides a necessary structural basis for the rotational connection between the anti-tilting support rod and the extended connecting plate. At the same time, the arrangement of the reinforcing ribs can significantly enhance the bending resistance of the extended connecting plate, making it not prone to bending deformation.

[0020] In a possible implementation, mounting end plates are fixedly arranged at both the front and rear ends of the guide rail housing, and the front and rear ends of the transmission lead screw are respectively rotatably connected to the corresponding mounting end plates.

[0021] With the above structural form, it provides a necessary structural basis for the rotational connection between the transmission lead screw and the guide rail housing.

[0022] In summary, the present utility model includes the following beneficial technical effects:

[0023] When transporting objects stacked relatively high, the end of the inclined support can be pushed by the lead screw angle adjustment mechanism, and then the anti-tilting support rod can be pushed by the inclined support to make it unfold. When the forklift tilts, the anti-tilting support rod can cooperate with the end auxiliary support mechanism at its end to play a supporting role, preventing the forklift from further tilting, facilitating the operator to adjust the position of the object and right the forklift, and being able to avoid damage to the object caused by the forklift overturning; and when the height of the transported object is not high, the anti-tilting support rod can be in a folded state through the lead screw angle adjustment mechanism, avoiding the extension of the anti-tilting support rod from affecting the use of the forklift.

Detailed implementation manners

[0030] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows:

[0031] As Figure 1 shown, an anti-roll transport forklift provided in this embodiment includes a manual hydraulic forklift body 1, with extended connecting plates 2 fixedly arranged on both sides thereof, an anti-roll strut 3, which is rotatably connected to the extended connecting plate 2 and plays a lateral support role, and a diagonal brace 5 is rotatably connected to the middle thereof, a screw rod angle adjustment mechanism 4, which is used to drive the end of the diagonal brace 5 away from the anti-roll strut 3 to move back and forth, thereby driving the anti-roll strut 3 to rotate, and an end auxiliary support mechanism 6, which is rotatably arranged at the outer end of the anti-roll strut 3. Through the above structural form, when transporting objects stacked relatively high, the screw rod angle adjustment mechanism 4 can be used to push the end of the diagonal brace 5 to move, and then the anti-roll strut 3 can be pushed by the diagonal brace 5 to expand. When the forklift rolls over, the anti-roll strut 3 can cooperate with the end auxiliary support mechanism 6 at its end to play a supporting role, preventing the forklift from tilting further, facilitating the operator to adjust the position of the object and right the forklift, and being able to avoid damage to the object caused by the forklift tipping over. Moreover, when the height of the transported object is not high, the anti-roll strut 3 can be in a retracted state through the screw rod angle adjustment mechanism 4, avoiding the extension of the anti-roll strut 3 from affecting the use of the forklift.

[0032] As Figure 2 shown, the screw rod angle adjustment mechanism 4 includes a guide rail housing 41, a sliding table 42 is slidably arranged in the guide rail housing 41, and the sliding table 42 is rotatably connected to the end of the diagonal brace 5 through a third rotating connecting piece 46. Through the above structural form, the movement of the end of the diagonal brace 5 can be driven by the sliding of the sliding table 42, and then the anti-roll strut 3 can be driven by the diagonal brace 5 to expand or retract.

[0033] Among them, a transmission screw 43 threadedly connected to the slide 42 is rotatably arranged in the guide rail housing 41, and a handwheel 44 is fixedly connected to the outer end of the transmission screw 43. Through the above-mentioned structural form, the operator can drive the transmission screw 43 with the handwheel 44, and then drive the slide 42 to slide back and forth through the thread engagement action, and this driving form has a self-locking effect, that is, when the transmission screw 43 does not rotate, the slide 42 cannot be displaced, so that it has the effect of fixing the position of the anti-roll support rod 3.

[0034] In addition, mounting end plates 45 are fixedly provided at both the front and rear ends of the guide rail housing 41, and the front and rear ends of the transmission screw 43 are rotatably connected to the corresponding mounting end plates 45 respectively. Through the above-mentioned structural form, the necessary structural basis is provided for the rotational connection between the transmission screw 43 and the guide rail housing 41.

[0035] like Figure 2 As shown, a hinged plate 32 is fixedly provided in the middle of the anti-roll support rod 3, which is rotatably connected to the end of the diagonal support 5 through a second rotatable connecting member 33. The above-mentioned structural form provides the necessary structural basis for the rotatable connection between the diagonal support 5 and the anti-roll support rod 3.

[0036] like Figure 3 As shown, the end auxiliary support mechanism 6 includes an auxiliary support rod 61, which is rotatably connected to the anti-roll support rod 3 through a threaded rotating rod 62, and its end is processed with a rounded corner. A locking nut 63 is threadedly connected to the threaded rotating rod 62. Through the above-mentioned structural form, the auxiliary support rod 61 can increase the contact area between the end of the anti-roll support rod 3 and the ground, thereby achieving a better anti-roll effect. At the same time, the auxiliary support rod 61 is rotatably connected to the anti-roll support rod 3, which can be easily folded and stored, and the locking nut 63 can fix the auxiliary support rod 61, so that it cannot rotate when subjected to force, thereby ensuring the role of force transmission.

[0037] Among them, a square block 65 is fixedly set at the bottom of the threaded rotating rod 62, and a square tube 64 that matches the size of the square block 65 is fixedly set at the end of the anti-roll support rod 3. When the square block 65 just leaves the square tube 64, the auxiliary support rod 61 is not in contact with the ground. Through the above-mentioned structural form, when the locking nut 63 is tightened, the square block 65 cannot escape from the square tube 64, and the auxiliary support rod 61 cannot rotate at this time, ensuring the role of force transmission. When the locking nut 63 is loosened, the square block 65 can escape from the square tube 64, and the auxiliary support rod 61 can be rotated to be retracted.

[0038] like Figure 2As shown in the figure, the extended connecting plate 2 is rotatably connected to the end of the anti-tilting strut 3 through the first rotating connecting piece 31. Two symmetrically arranged reinforcing ribs 21 are fixedly arranged on the upper end surface of the extended connecting plate 2, and the ends of the reinforcing ribs 21 are welded to the manual hydraulic forklift body 1. Through the above structural form, a necessary structural basis is provided for the rotational connection between the anti-tilting strut 3 and the extended connecting plate 2. At the same time, the setting of the reinforcing ribs 21 can significantly enhance the bending resistance of the extended connecting plate 2, making it not prone to bending deformation.

[0039] The working principle and process of the present utility model are as follows:

[0040] When transporting objects stacked relatively high, the end of the inclined strut 5 can be pushed to move through the screw rod angle adjustment mechanism 4, and then the anti-tilting strut 3 can be pushed to unfold through the inclined strut 5. When the forklift tilts, the anti-tilting strut 3 can cooperate with the end auxiliary support mechanism 6 at its end to play a supporting role, preventing the forklift from further tilting, facilitating the operator to adjust the position of the object and right the forklift, and avoiding damage to the object caused by the overturning of the forklift.

[0041] The specific operation of the above process is that the operator can drive the transmission screw rod 43 to drive through the handwheel 44, and then drive the slide table 42 to slide back and forth through the thread meshing effect. The sliding of the slide table 42 drives the end of the inclined strut 5 to move, and then drives the anti-tilting strut 3 to unfold or retract through the inclined strut 5. And this driving form has a self-locking function, that is, when the transmission screw rod 43 does not rotate, the slide table 42 cannot displace, so as to fix the position of the anti-tilting strut 3.

[0042] When the height of the transported object is not high, the anti-tilting strut 3 can be in a retracted state through the screw rod angle adjustment mechanism 4 to avoid the influence of the extension of the anti-tilting strut 3 on the use of the forklift.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present utility model, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
