Description

  The present invention relates to a tire cleaning device for removing deposits such as steel slag and soil attached to tires such as trucks and dump trucks, and a slag unit used in the device.

  A deformation imparting member that deforms the tire of the vehicle is provided in the water of a pool such as a dump truck, and the tire of the vehicle passing through the pool is locally deformed so that it fits on the surface of the tire or the groove. 2. Description of the Related Art A tire cleaning device that removes dirt, mud, and the like attached thereto is known as a prior art (see, for example, Patent Documents 1 and 2).

  The deformation imparting member of the tire cleaning device of Patent Document 1 is a large number of girders made of H-section steel or the like having a rising portion from the bottom of the pool and a flat portion on the upper surface, and these are the direction in which the vehicle passes with respect to the pool.

  Since the tire cleaning devices described in Patent Documents 1 and 2 are provided with a large number of deformation imparting members that locally deform the tire so as to expand the groove of the tire, the vehicle is orthogonal to the direction of travel of the vehicle. When the vehicle passes through the pool, the contact length of the tire with the deformation imparting member is limited by the tire width, and there are relatively few opportunities to deform the tire. For this reason, the cleaning efficiency of the tire is not good. In order to remove tire deposits sufficiently, it is necessary to increase the number of deformation imparting members and form a long pool, but in that case, the installation cost is high and the installation place needs to be wide. There is.

  Further, since the tire cleaning devices of Patent Documents 1 and 2 allow the vehicle to pass through the pool while the tire is locally deformed by the arranged deformation imparting members, the vertical movement of the vehicle is absorbed by the local deformation of the tire. Thus, a vehicle passing through the pool at a low speed passes through the pool with almost no vibration. Since the tire deposits are removed only by locally deforming the tire in this way, the tire cleaning efficiency is not good. In this respect as well, in order to increase the cleaning efficiency of the tire, it is necessary to increase the number of deformation imparting members used to form a long pool, but in that case, the installation cost may be high and the installation location may be widely required. .

Therefore, each lower member 22 preferably extends in a direction orthogonal to each main beam 11. These lower members 22 are arranged at intervals in the longitudinal direction of the pool 2 and the main girders 11, and are preferably arranged at regular intervals. These lower members 22 are made of section steel, for example, H-section steel. As shown in FIG. 4, flanges 22b and 22c are continuously provided at both ends of the web 22a. In the H-shaped steel, the web 22a is vertical and the flanges 22b and 22c are horizontal, and the lower flange 22c is supported on the main girder 11. The upper flange 22b is used as a flat upper end portion.

It is fixed by welding or the like and forms a left saw portion 21a together with each lower member 22. These left upper members 23 are fixed to each lower member 22 at an angle and spaced from each other, and preferably parallel to each other. The left slat part 21a forms a road surface in contact with the left tire of the vehicle passing thereabove. The arrangement pitch of the left upper member 23 is preferably 150 mm, for example.

  Similarly, as shown in FIG. 5, the plurality of right upper members 24 are positioned between the center in the longitudinal direction of the lower member 22 and the right end with respect to the vehicle passing direction with respect to the pool 2. It is fixed on the part by welding or the like and forms a right side saw part 21b together with each lower member 22.

It is tilted in reverse. The arrows in FIG. 5 indicate the direction in which the left upper member 23 and the right upper member 24 are separated. The angle of the left upper member 23 and the right upper member 24 with respect to the longitudinal direction of the pool 2 is 40 ° to 50 °, and when the angle is less than 40 ° or exceeds 50 °, the groove M of the tire T becomes the right upper member 23 and the right side. When the angle is 45 °, the groove M of the tire T is most easily and properly fitted into the left upper member 23 and the right upper member 24 when the angle is 45 °.

  The plurality of left upper members 23 and the same number of right upper members 24 are, for example, line symmetric with respect to the center line of the upstream saw unit 21, but this need not be the case. In the first embodiment, the lower members 22 are used in common for the left saw portion 21a and the right saw portion 21b. Thus, since the left sword part 21a and the right sword part 21b are unitized, the handling and the installation work to the pool 2 are easy compared with the case where both the saw parts are independent.

  Next, the downstream side saw unit 31 will be described. The downstream side saw unit 31 is disposed downstream of the upstream side saw unit 21 downstream of the upstream side saw unit 21 in the direction of travel of the vehicle. As shown in FIG. 6, the downstream saw unit 31 has the same configuration as the upstream saw unit 21, and includes a plurality of lower members 32, a plurality of left upper members 33, and a plurality of right upper members 34. is doing.

  Each lower member 32 intersects with the direction of travel of the vehicle passing through the pool 2 and is preferably orthogonal to each other. Therefore, the lower member 32 preferably extends in the direction orthogonal to each main beam 11 and the pool 2. The main girders 11 are arranged at intervals in the longitudinal direction, preferably at regular intervals. These lower members 32 are made of a shaped steel, for example, H-shaped steel, like the lower member 22, and their arrangement in the pool 2 is the same as that of the lower member 32. That is, the H-shaped steel forming the lower member 32 is formed by continuously providing flanges at both ends of the web, and a plurality of reinforcing plates are welded at predetermined intervals between the flanges. In the lower member 32, the lower side flange is supported on the main girder 11 in a state in which the web is set up vertically and the flange is arranged horizontally. The upper flange is used as a flat upper end.

  Each of the plurality of left upper members 33 and right upper members 34 is made of a steel round bar, and the thickness thereof is a thickness that can enter a groove M formed in a tire T of a vehicle passing through the pool 2. For example, the diameter is 19 mm.

  The plurality of left upper members 33 are positioned between the center in the longitudinal direction of the lower member 32 and the left end with respect to the direction of travel of the vehicle with respect to the pool 2, and are fixed on the upper end portion of each lower member 32 by welding or the like. A left saw portion 31 a is formed together with each lower member 32. These left upper members 33 are fixed obliquely across the respective lower members 32, spaced from each other, and preferably parallel to each other. The left slat part 31a forms a road surface that is in contact with the left tire of the vehicle that passes therethrough. The arrangement pitch of the left upper member 33 is preferably narrower than the arrangement pitch of the left upper member 23 in the upstream saw unit 21, for example, 75 mm.

  Similarly, the plurality of right upper members 34 are positioned between the center in the longitudinal direction of the lower member 32 and the right end on the basis of the vehicle passing direction with respect to the pool 2, and are welded or the like on the upper end portion of each lower member 32. The right side saw portion 31b is formed together with each lower member 32. These left upper members 34 are fixed obliquely across the respective lower members 32, spaced from each other, and preferably parallel to each other. The right slat part 31b forms a road surface in contact with the right tire of the vehicle passing thereabove. The arrangement pitch of the right upper member 34 is also preferably narrower than that of the right upper member 34 in the upstream saw unit 21, for example, 75 mm.

  Each of the plurality of left upper members 33 and the plurality of right upper members 34 is inclined to be opposite to each other so that the distance between them is increased toward the downstream side in the vehicle traveling direction. The arrow in FIG. 6 indicates the direction in which the left upper member 33 and the right upper member 34 are separated. The angle of the left upper member 33 and the right upper member 34 with respect to the longitudinal direction of the pool 2 is 40 ° to 50 °, and when the angle is less than 40 ° or exceeds 50 °, the groove M of the tire T becomes the right upper member 33 and the right side. When the angle is 45 °, the groove M of the tire T is most easily and properly fitted into the left upper member 33 and the right upper member 34 when the angle is 45 °.

  The plurality of left upper members 33 and the same number of right upper members 34 are, for example, line symmetric with respect to the center line of the downstream saw unit 31, but this need not be the case. The lower members 32 are commonly used for the left and right slats 31a and 31b. Thus, since the left sword part 31a and the right sword part 31b are unitized, the handling and the installation work to the pool 2 are easy compared with the case where both the saw parts are independent.

  Since each upstream saw unit 21 and each downstream saw unit 31 are arranged so as to be spread on the main beam 11, they may or may not be fixed to the main beam 11. . The main beam 11, each upstream side saw unit 21, and each downstream side saw unit 31 form a saw device. The snowboard device is installed in the pool 2 so as to be inclined with respect to the pool 2 so as to be higher toward the outlet 2b side. The height of the inclined upper end portion of the downstream side saw unit 31 is substantially the same as that of the outlet portion 2b.

  The outlet 2b has a grating groove 37 (see FIG. 3). The grating groove 37 has a groove portion extending over the entire width of the pool 2 and a groove portion that connects the center of the groove portion and the inside of the pool 2 and has a T-shape in plan view. The upper end opening of the grating groove 37 is covered with a metal grating 38 having a large number of slots.

  The tire cleaning device 1 is used by storing water in the pool 2. The water level H of the accumulated water is indicated by a two-dot chain line in FIG. The water level H is set so as to be substantially the same as the height of the portion where the upstream saw unit 21 and the downstream saw unit 31 are continuous. As a result, the upstream side saw unit 21 is soaked in water, the downstream side saw unit 31 is disposed at a position higher than the water surface of the pool 2, and the tire T of the vehicle passing through the pool 2 at the deepest part. About 1/3 of the tire diameter can be immersed from the lower end.

  In order to clean the tire T of the vehicle that is about to go out of the steel slag yard to the public road with the tire cleaning device 1 having the above-described configuration, the vehicle is moved at the slowest speed to the pool 2 of the tire cleaning device 1 from its entrance 2a. It is made to pass toward the exit part 2b. During the passage, the tire T is washed by passing the tire T through the snowboard device.

  That is, as the vehicle passes through the pool 2, the left and right tire tires T of the vehicle roll on the left and right side saw portions 21 a and 21 b of the upstream side saw unit 21 disposed underwater. Similarly, the left and right tires T of the vehicle roll on the left and right side saw portions 31a and 31b of the downstream side saw unit 31 on the water.

  Therefore, in water, the slanted left upper member 23 provided by the left saw part 21a and the slanted right upper member 24 provided by the right saw part 21b and the saw part 21b are not relative to the tire T in the width direction. In particular, it is in contact with the direction that obliquely intersects the width direction of the tire T. Thereby, the left upper member 23 can secure a long length for locally deforming the left tire T passing thereabove, and similarly, the right upper member 24 locally disposes the right tire T passing therethrough. Can be secured long.

  In addition, the left and right tires T run on the left upper member 23 and the right upper member 24 with the local deformation described above, and the groove M of the tire T is formed on the left upper member 23 and the right upper member 24 at different timings. Since the tire T passes through the upstream saw unit 21 while repeating the behavior of the tire T being lowered by fitting, vibration is imparted to the vehicle body together with the tire T in the vertical direction.

  Therefore, the opportunity of contact with the tire T of the left and right upper members 23 and 24 as described above is increased, and thereby the local deformation of the tire T and the vertical vibration applied to the tire T, the vehicle tire Deposits such as steel slag and soil / mud adhering to T can be efficiently removed in water.

  In such cleaning, the angle of the left upper member 23 and the right upper member 24 with respect to the vehicle traveling direction is approximately 45 °, and this angle is substantially the same as the angle of the groove M of the tire T of a vehicle such as a dump truck or a truck. As a result, the groove M of the tire T is easily fitted to the left and right upper members 23 and 24, and the tire T can be reliably vibrated.

  In addition, since the left and right upper members 23 and 24 are fixed to the upper surface of the flange 22b that is continuous with the upper end of the web 22a of each lower member 22 made of H-shaped steel, the groove M of the tire T has the upper members 23 and 24. When the fitting is finished, the tire T is supported by the flange 22b of H-shaped steel. For this reason, it can suppress that the weight of a vehicle adds to each upper member 23 and 24 excessively, and deform | transforms these upper members 23 and 24. FIG.

  Subsequent to the above cleaning, the vehicle tire T passes through the water-side downstream saw unit 31 disposed on the downstream side in the vehicle passage direction with respect to the water-side upstream saw unit 21. In this case, the downstream side saw unit 31 is continuous with the upstream side saw unit 21 without a gap, and is disposed obliquely at the same angle as the unit 21, and between the upstream side saw unit 21 and the downstream side saw unit 31, There are no boundaries such as steps that hinder traffic. Therefore, it is possible to smoothly transfer the vehicle to the downstream side saw unit 31 and pass the vehicle to the pool 2.

  The downstream side saw unit 31 having the same configuration as the upstream side saw unit 21 has a left side saw portion 31a and a right side saw portion 31b, and is further locally deformed with respect to the tire T about to pass therethrough. Give vibration. For this reason, the deposits that could not be removed by the upstream side saw unit 21 in water can be removed while draining, and the removal reliability is high.

In this case, the arrangement pitch of the plurality of upper members 33, 34 that the downstream side saw portions 31 a, 31 b have is narrower than the arrangement pitch of the plurality of upper members 23, 24 that the downstream side saw portions 21 a, 21 b have. For this reason, since the downstream saw unit 31 gives more fine local deformation and vibration to the tire T than the upstream saw unit 21 in water, the removal reliability of the deposits that could not be completely removed by the submerged portion in the water. Since the deposits can be efficiently removed from the tire T as described above, the length of the pool 2 can be shortened and a compact tire cleaning device 1 can be constructed. The installation cost can be reduced and the installation location can be reduced.

Further, the draining can suppress the road surface continuing to the outlet 2b of the pool 2 from being soiled with steel slag, mud, etc., and even if the road surface is soiled, the range can be shortened. It is preferable for environmental pollution measures. When the vehicle passes through the pool 2, the water in the pool 2 is pushed in the traveling direction of the vehicle, but the water flows into the grating groove 37 and returns to the lower side of the saw device, so that the outlet 2b Over the pool 2 is prevented.
Further, when the loaded weight of the vehicle to be cleaned is light as described above, the vehicle may try to slip on the device in which the lower members 22 and 32 extend. However, the left and right upper members 23, 24 of the upstream side saw unit 21 are obliquely arranged opposite to each other, and the left and right upper members 33, 34 of the downstream side saw unit 31 are also obliquely directed opposite to each other. Therefore, the slip can be suppressed. For this reason, a vehicle can be smoothly passed through the pool 2.

  Deposits such as steel slag removed from the tire T by the tire cleaning described above are deposited on the bottom of the pool 2 through the gaps of the sawing device. As the water in the pool 2 is sucked into the sedimentation pit 4, the sediment is moved into the sedimentation pit 4 deeper than the pool 2, sucked out by the sand pump P, and appropriately processed by a processing device.

  In the first embodiment, the upstream side saw unit 21 and the downstream side saw unit 31 may have the same configuration. In this case, a portion of the saw device immersed in water forms an upstream side saw unit, and a portion of the saw device disposed on the water forms a downstream side saw unit. Even with such a configuration, the problems of the present invention can be solved.

  Next, a second embodiment of the present invention will be described with reference to FIG. About the structure similar to the structure of 1st Embodiment, the code | symbol same as 1st Embodiment is attached | subjected, the description is abbreviate | omitted, and only the structure different from 1st Embodiment is demonstrated hereafter.

  In the second embodiment, the snowboard device described in the first embodiment is divided into left and right. Therefore, the left side saw unit 41 and the right side saw unit 42 are used instead of the upstream side saw unit and the downstream side saw unit described in the first embodiment.

  The left sword unit 41 includes a left side portion of the main girder 11 described in the first embodiment, an upstream left sword portion 21a installed in water, and a downstream left side disposed continuously on the water. It is formed with the slat part 31a. Similarly, the right slat unit 42 is disposed to be continuous with the right part of the main girder 11 described in the first embodiment, the upstream right slat part 21b installed in water. It is formed with the right side saw 31b on the downstream side.

  As a result, the upstream left side saw portion 21a and the right side saw portion 21b disposed in the water are independently provided, and the downstream left side saw portion 31a and the right side saw portion disposed on the water. 31b are provided independently of each other.

  Configurations other than those described above are the same as those in the first embodiment, including configurations not shown in FIG. Therefore, also in the tire cleaning apparatus of the second embodiment, for the reason already described in the first embodiment, the problem of the present invention is solved, and the steel slag and the like attached to the tire T of the vehicle passing through the pool 2 Can be removed efficiently.

  In addition, this invention is not restrict | limited to the said both embodiment. For example, it is also possible to implement as a configuration in which a plurality of pools 2 in which a snowboard device is disposed are continuously provided in a straight line.
