Description

Technical Field

[0001] The utility model belongs to the technical field of roller structures, and in particular relates to a rolling device used in a heavy-load transport system. Background Art

[0002] The common existing heavy-load handling systems mainly include various types of steel structure handling vehicles, and their safe handling weight generally ranges from several hundred kilograms. Therefore, correspondingly, for the above-mentioned handling vehicles, the most critical performance is support stability and braking stability. On the contrary, power performance, quietness, etc. are secondary.

[0003] As for the above-mentioned rolling device, one of the structural requirements for achieving support and braking stability is: first, the device itself should ensure the integrity of the structure as much as possible, and try to avoid grooving and drilling in the vertical direction; second, the braking effect should include not only the friction method, but also the engagement method, to ensure that the above-mentioned transport vehicle is not easy to move after it is in place.

[0004] For example, a Chinese utility model patent with authorization announcement number CN220865128U and authorization announcement date 2024.04.30 discloses a high-load transport cart caster, including a mounting plate, a slide groove is provided at the bottom of the mounting plate, the inner wall of the slide groove is a symmetrical structure and two sliders are slidably connected, the inner wall of the slide groove is rotatably connected with a bidirectional threaded rod, both ends of the bidirectional threaded rod respectively penetrate the mounting plate and extend to the outside thereof, the bidirectional threaded rod respectively penetrates the two sliders and is threadedly connected to them, and a fixing plate is fixed at the bottom of the two sliders.

[0005] The general structural principle and advantages of the transport cart caster in this utility model patent are as follows: the two-way threaded rod is driven to rotate by turning the knob, so that the two sliders move synchronously in opposite directions along the inner wall of the slide groove, and the two sliders respectively drive the fixed plates to move when they move, and the two fixed plates respectively drive the rubber pads to move when they move, and the tire can be effectively fixed by squeezing the anti-skid groove at the bottom of the rubber pad with the outer wall of the tire. At the same time, according to the wear of the rubber pad, the two-way threaded rod can be rotated so that the rubber pad can always squeeze the tire.

[0006] However, in actual use, the transport cart caster still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0007] First, the tire fixing method is only friction fixing, which is far from enough, and the friction method itself is an unstable fixing method, which cannot securely fix the heavy and inertial transport cart;

[0008] Second, the above-mentioned friction fixing method requires relatively long time and precise operation of the knob structure to open, which is not convenient and practical.

[0009] Therefore, in summary, there is an urgent need for a new type of rolling device with relatively simple triggering operation and stable braking method itself, which can be used in various large-load handling vehicles to make it difficult to move when braking. Content of the Utility Model

[0010] The utility model provides a rolling device for a large-load handling system. By setting installation bolts, rollers, grooved inclined panel units, perforated vertical plate units, and combined column units on the mounting plate, the following can be achieved: 1. The grooved inclined panel unit can engage with the rollers to ensure a more stable braking state; 2. After the grooved inclined panel unit is removed, the rollers can be initially engaged, or the rollers can roll onto the grooved inclined panel unit by themselves to trigger further engagement and fixation. The whole operation does not require long-term fine adjustment, which is very simple and convenient.

[0011] The technical solution adopted by the utility model to solve the above problems is: a rolling device for a large-load handling system, the structure includes a mounting plate, installation bolts, and rollers, and also includes a grooved inclined panel unit arranged on the side of the mounting plate and used to fix the rollers by engaging with the rollers after being removed, a perforated vertical plate unit arranged on the mounting plate and used to install the rollers, and a combined column unit arranged on the rollers and inserted into the perforated vertical plate unit.

[0012] A further preferred technical solution lies in: the grooved inclined panel unit includes an inclined panel with a right trapezoidal vertical cross-sectional shape and a tip for inserting between the roller and the ground, and an arc groove arranged on the upper surface of the inclined panel and used to engage with the roller that has been lifted off the ground.

[0013] A further preferred technical solution lies in: the perforated vertical plate unit includes a vertical plate arranged on the mounting plate, and an installation hole arranged on the vertical plate and used to insert the combined column unit.

[0014] A further preferred technical solution lies in: the combined column unit includes a central shaft arranged on the vertical side of the roller and inserted into the installation hole, a threaded column arranged on the end face of the central shaft, and at least two limit nuts arranged on the threaded column and used to block and engage with the vertical plate.

[0015] A further preferred technical solution lies in: the grooved inclined panel unit also includes a fixing hole arranged on the inclined panel, and a fixing rod arranged on the side of the mounting plate and used to insert into the fixing hole.

[0016] A further preferred technical solution is that: the grooved inclined panel unit further includes an installation groove provided on the side surface of the installation plate and used for inserting the fixing rod.

[0017] A further preferred technical solution is that: the perforated vertical plate unit further includes a plurality of limiting rods provided on the vertical plate; the combined column unit further includes a protruding column provided on the end surface of the threaded column, and a limiting groove provided on the protruding column and used for inserting the fixing rod that has been pulled out.

[0018] A further preferred technical solution is that: the perforated vertical plate unit further includes fixing grooves provided on the upper end surface and the side surface of the vertical plate and used for clamping the installation plate, and the grooved inclined panel unit is arranged on the upper end surface of the vertical plate.

[0019] A further preferred technical solution is that: the number of the grooved inclined panel units is 2.

[0020] A further preferred technical solution is that: the number of the limiting rods is at least 2. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is only the preferred embodiment of the present invention, and does not limit the scope of the present invention.

[0035] As shown in the attached Figures 1-9 As shown in the figure, a rolling device for a large-load handling system includes a mounting plate 11, a mounting bolt 12, and a roller 13. It also includes a grooved inclined panel unit 1 provided on the side of the mounting plate 11 and used to fix the roller 13 by engaging the roller 13 after being removed, a perforated vertical plate unit 2 provided on the mounting plate 11 and used to mount the roller 13, and a combined column unit 3 provided on the roller 13 and inserted into the perforated vertical plate unit 2.

[0036] In this embodiment, the mounting plate 11 supports the handling vehicle frame and can be screwed to the latter through the mounting bolt 12, so that the rolling device can be stably installed in the above-mentioned large-load handling system, that is, stably connected to the above-mentioned handling vehicle frame.

[0037] Among them, the number of the mounting bolts 12 is 4, and the numbers of the grooved inclined panel unit 1, the perforated vertical plate unit 2, and the combined column unit 3 are all 2. The two perforated vertical plate units 2 and the two combined column units 3 are respectively located on both sides of the roller 13, so as to stably install the roller 13 sufficiently.

[0038] In addition, the word "inclined surface" of the grooved inclined panel unit 1 means that its structural shape is essentially similar to a wedge, and the two can be stuck between the roller 13 and the ground together or alternatively, so as to achieve a sufficiently stable braking effect. The strength of this braking method is higher than the existing common "brake pad" method. For details, please refer to the attached Figure 8 .

[0039] The term "grooved" in the grooved inclined panel unit 1 means that the roller 13 can roll along the above-mentioned inclined plane to the groove thereon, so as to brake and fix the hand truck more fully. Then, the roller 13 rolls back in the reverse direction to release the braking state. The braking stability of this method is higher than the method of wedging in the above-mentioned wedge. For details, please refer to the appendix Figure 9 So far, the rolling device already has the above-mentioned second and third braking methods, and these two methods can be used alternatively.

[0040] The grooved inclined panel unit 1 includes an inclined panel 101 with a vertical cross-sectional shape of a right trapezoid and a tip for inserting between the roller 13 and the ground, and an arc groove 102 provided on the upper surface of the inclined panel 101 and used for clamping the roller 13 that has been lifted off the ground.

[0041] In this embodiment, the "oblique waist" of the above-mentioned right trapezoid corresponds to the inclined plane of the inclined panel 101, and the arc groove 102 is provided at the position of the "upper base" of the above-mentioned right trapezoid. So far, the above-mentioned inclined plane and the arc groove 102 can be used alternatively.

[0042] When clamping and inserting to fix the roller 13 through the above-mentioned inclined plane, one or two of the inclined panels 101 can correspond to a single roller 13; when clamping the roller 13 through the arc groove 102, one inclined panel 101 can correspond to a single roller 13, and the other inclined panel 101 can be idle on the side of the mounting plate 11.

[0043] Among them, the removal operation, insertion operation, and reinstallation operation of the inclined panel 101 can all be completed manually.

[0044] The perforated vertical plate unit 2 includes a vertical plate 201 provided on the mounting plate 11, and a mounting hole 202 provided on the vertical plate 201 and used for inserting the combined column unit 3.

[0045] In this embodiment, the vertical plate 201 is either screwed or welded to the mounting plate 11. The roller 13 is clamped between the two vertical plates 201, so that it can have basic installation stability and can only rotate and roll without shifting significantly left and right.

[0046] Among them, the shape of the mounting hole 202 is circular, and existing common bearings and / or lubricating oil are provided thereon as required.

[0047] The combined column unit 3 includes a central shaft 301 provided on the vertical side surface of the roller 13 and inserted into the mounting hole 202, a threaded column 302 provided on the end surface of the central shaft 301, and at least two limit nuts 303 provided on the threaded column 302 and used for blocking and clamping the vertical plate 201.

[0048] In this embodiment, the roller 13, the central shaft 301 and the threaded post 302 are integrally formed. The vertical plate 201 first sleeved on the central shaft 301 and then connected to the mounting plate 11. The two limit nuts 303 are clamped with each other, so that it can become a head blocking structure with sufficient upper limit on the central shaft 301 and still be detachable, avoiding large left and right swings of the roller 13 during the rolling process.

[0049] Although the roller 13 itself already has a preliminary left and right limit effect between the two vertical plates 201, the setting of the limit nuts 303 can not only strengthen the above left and right limit effect, but also make the roller 13 not need to and will not touch and wear the vertical plate 201, providing a structural basis for adding an elastic coating material to the roller 13.

[0050] Finally, each roller 13 corresponds to 2 central shafts 301, 2 threaded posts 302 and 4 limit nuts 303, so that it can be stably installed vertically and fully limited horizontally.

[0051] The grooved inclined panel unit 1 further includes a fixing hole 103 provided on the inclined panel 101, and a fixing rod 104 provided on the side of the mounting plate 11 and used for inserting into the fixing hole 103.

[0052] In this embodiment, the fixing rod 104 is inserted into the fixing hole 103 to hang and fix the inclined panel 101, which is one of the feasible ways for the grooved inclined panel unit 1 to be stably installed on the side of the mounting plate 11 and convenient for taking and placing.

[0053] The grooved inclined panel unit 1 further includes a mounting groove 105 provided on the side of the mounting plate 11 and used for inserting the fixing rod 104.

[0054] In this embodiment, the shape of the mounting groove 105 is circular, and there is an appropriate interference fit between it and the fixing rod 104, avoiding accidental dropping of the fixing rod 104 and the inclined panel 101, and also providing a structural basis for the replacement function and new function after the fixing rod 104 is pulled out.

[0055] The perforated vertical plate unit 2 further includes a plurality of limiting rods 203 provided on the vertical plate 201; the combined column unit 3 further includes a protruding column 304 provided on the end face of the threaded post 302, and a limiting groove 305 provided on the protruding column 304 and used for inserting the fixing rod 104 that has been pulled out.

[0056] In this embodiment, the first braking method of the rolling device needs to be achieved together through the limiting rod 203, the protruding column 304, the limiting groove 305, and the fixing rod 104. The specific method is as follows:

[0057] First, the fixing rod 104 is pulled out from the fixing hole 103. At this time, the corresponding inclined panel 101 can be removed and left idle;

[0058] Second, the fixing rod 104 is inserted into the limiting groove 305. At this time, the limiting rod 203 is within the rotation range of the fixing rod 104, so the latter can be blocked, which is equivalent to fixing and braking the roller 13. However, it should be noted that this braking state is a range type, and the trolley can still roll and shift within a small range at this time. For specific reference, please refer to the appendix Figure 7 .

[0059] Among them, the protruding column 304, the threaded column 302, and the central axis 301 are integrally formed, and the central axes of the three coincide. The protruding column 304 is not provided on the threaded column 302 located inside the trolley. Similarly, the limiting rod 203 is only provided on the outer side surface of the vertical plate 201 to ensure the unilateral and range-type braking effect that the fixing rod 104 on the outside of the roller 13 engages with the limiting rod 203.

[0060] Finally, the main materials of the grooved inclined panel unit 1, the perforated vertical plate unit 2, and the combined column unit 3 are all high-strength steel, and the support effect and braking effect need to be achieved through the structural strength of the material itself.

[0061] Generally, the first braking method is not used in combination with the second and third methods, and it is applicable to scenarios where the accuracy requirements for the braking position are relatively low.

[0062] The perforated vertical plate unit 2 further includes fixing grooves 204 provided on the upper end surface and the side surface of the vertical plate 201 and used for engaging the mounting plate 11. The grooved inclined panel unit 1 is provided on the upper end surface of the vertical plate 201.

[0063] In this embodiment, the fixing groove 204 includes a groove bottom surface and a groove side surface. The above groove bottom surface is used to support the frame of the trolley, and the above groove side surface is used to fit the side surface of the mounting plate 11. For the above welding method, it can be carried out at both the groove bottom surface and the groove side surface. For the above screwing method, it is generally provided on the corresponding vertical plate 201 at the groove side surface.

[0064] Among them, a part of the upper end surface of the vertical plate 201 is exposed at this time, exceeding the lower surface of the mounting plate 11. Therefore, it can support the relatively unstable inclined panel 101 that may rotate vertically at this time, so that the inclined panel 101 maintains a sufficiently stable horizontal state and fixed state when idle.

[0065] However, the interference fit insertion effect between the fixing hole 103 and the fixing rod 104 is still the main connection position where the inclined panel 101 is stably installed and does not fall off.

[0066] The number of the grooved inclined panel units 1 is two.

[0067] In this embodiment, when the inclined panel 101 is inserted and clamped with the roller 13, at most two are needed. Therefore, each roller 13 corresponds to two grooved inclined panel units 1. For the specific usage method, please refer to the appendix Figure 8 .

[0068] The number of the limiting rods 203 is at least two.

[0069] In this embodiment, several limiting rods 203 surround the mounting hole 202 and are arranged in a circle on the outer side surface of the vertical plate 201, and the number thereof is 2 - 4, so as to achieve a sufficient and appropriate range blocking and interval blocking effect on the fixing rod 104. For the specific details, please refer to the appendix Figure 7 .

[0070] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various modifications can be made without departing from the gist of the present invention. These are all non - creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present invention.
