Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary adjustment devices, in particular to a sensor adjustment device and maintenance equipment. Background Art

[0002] A truck scale, also known as a floor scale, is a large scale installed on the ground. It is usually used to obtain the cargo tonnage of load-bearing transport equipment. It is the main weighing equipment used for bulk cargo measurement in factories and mines. Among them, the sensor is the main device for the truck scale to obtain the cargo tonnage.

[0003] At present, the sensors used in existing truck scales generally consist of an upper supporting bowl, a lower supporting bowl, a sensor body for installing the lower supporting bowl, and a steel ball placed between the upper supporting bowl and the lower supporting bowl. During the weighing process of the truck scale, the upper supporting bowl transmits pressure to the steel ball, so that the steel ball transmits pressure through the lower supporting bowl to deform the conversion element on the sensor body, thereby realizing the conversion of pressure signal to electrical signal, and finally achieving weighing.

[0004] During the use of the truck scale, the upper and lower support bowls are easily misaligned due to the overspeed of the load-carrying transport equipment or the influence of the scale body on the sensor, causing the steel ball to deviate from the center of the upper and lower support bowls, resulting in a large deviation in the weighing value obtained by the truck scale. Therefore, it is necessary to adjust the sensor, but the existing adjustment device usually requires multiple adjustments and verifications when adjusting the sensor, resulting in low adjustment efficiency and reduced weighing detection efficiency of the load-carrying transport equipment. Utility Model Content

Since the upper support bowl and the lower support bowl are spaced apart along the first direction, and the second direction is perpendicular to the first direction, when the first alignment member is placed on one side of the sensor along the second direction, the first alignment member can simultaneously abut against the side walls of the upper support bowl and the lower support bowl on the same side of the second direction, thereby keeping the side walls of the upper support bowl and the lower support bowl along the second direction parallel to the first direction. At this time, the centers of the bowl sockets of the upper support bowl and the lower support bowl correspond to each other up and down, and the bowl sockets are curved, so the steel ball can fall stably on the lower side under the action of gravity. The center of the bowl socket of the support bowl is formed by the first alignment member, so that the steel ball remains in the center of the bowl socket of the upper support bowl and the lower support bowl. When the upper support bowl and the lower support bowl are misaligned, the detection accuracy of the sensor can be adjusted through the first alignment member. On this basis, when the first alignment member is arranged on one side of the sensor along the second direction, the second alignment member can be arranged on the other side of the sensor along the second direction. At this time, the second alignment member can be offset against the first alignment member, thereby supporting the first alignment member along the second direction. The operation is simple and convenient, and the first alignment member can be quickly positioned and stably placed, thereby facilitating the rapid adjustment of the relative misalignment of the upper support bowl and the lower support bowl, which can effectively improve the adjustment efficiency of the detection accuracy of the sensor, and then improve the weighing detection efficiency of the load-carrying transportation equipment.

[0008] Optionally, the second alignment member is extended along the first direction and is opened relative to the first alignment member. When the second alignment member and the first alignment member are respectively arranged on both sides of the sensor along the second direction, the inner wall of the second alignment member is against the side wall of the upper support bowl along the second direction and the side wall of the lower support bowl along the second direction.

[0012] Optionally, in the first direction, the size of the outer wall panel is greater than or equal to the size of the inner wall panel.

[0013] Optionally, the sensor adjustment device further comprises an alignment structure, wherein the alignment structure is mounted on the first alignment member and / or the second alignment member, and the second alignment member is configured to be aligned with and offset from the first alignment member via the alignment structure.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] It should be noted that, in the coordinate system XYZ provided herein, the positive direction of the X axis represents the right, the reverse direction of the X axis represents the left, the positive direction of the Y axis represents the front, the reverse direction of the Y axis represents the back, the positive direction of the Z axis represents the top, and the reverse direction of the Z axis represents the bottom. At the same time, it should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0029] On the one hand, an embodiment of the utility model provides a sensor adjustment device for adjusting a sensor 1, wherein the sensor 1 includes an upper supporting bowl 11 and a lower supporting bowl 12 which are relatively open and spaced apart along a first direction, and the sensor adjustment device includes a first alignment member 2 and a second alignment member 3, wherein the first alignment member 2 is open toward the second direction and extends along the first direction, and the second direction is perpendicular to the first direction, and the first alignment member 2 is used to be arranged on one side of the sensor 1 along the second direction so that the side wall of the upper supporting bowl 11 along the second direction and the side wall of the lower supporting bowl 12 along the second direction are both against the first alignment member 2, and the second alignment member 3 is used to be arranged on the other side of the sensor 1 along the second direction and against the first alignment member 2.

[0030] It should be noted that in the present utility model, Figure 1 and Figure 2 As shown, the first direction is the Z-axis direction, and the second direction is the X-axis direction.

[0031] In the prior art, the sensor 1 is generally a bridge sensor, which is composed of an upper supporting bowl 11 and a lower supporting bowl 12 which are relatively open and spaced apart along a first direction, that is, spaced apart along the upper and lower directions and are arranged in a columnar shape. The curved concave bowls of the upper supporting bowl 11 and the lower supporting bowl 12 are relatively arranged and can accommodate a steel ball between the upper supporting bowl 11 and the lower supporting bowl 12. When the scale body of the truck scale is not subjected to force, the steel ball is located on the lower supporting bowl 12 and spaced apart from the upper supporting bowl 11. When the sensor 1 is working, when the scale body of the truck scale is subjected to force, the upper supporting bowl 11 and the lower supporting bowl 12 cooperate to clamp the steel ball. At this time, the steel ball needs to be located at the center of the bowl sockets of the upper supporting bowl 11 and the lower supporting bowl 12 to maintain the accuracy of weighing. When the transportation equipment to be weighed, such as a car, enters and exits the scale body and when the objects it transports are unbalanced, it is easy to cause the upper supporting bowl 11 and the lower supporting bowl 12 to be relatively misaligned, causing the steel ball to leave the center of the bowl socket of the upper supporting bowl 11 or the lower supporting bowl 12.

[0032] Therefore, in this embodiment, if Figure 1 As shown, a first alignment member 2 and a second alignment member 3 are provided to form a sensor adjustment assembly, wherein the first alignment member 2 is provided with an opening toward the second direction and is extended along the first direction, that is, the length direction of the first alignment member 2 is the first direction. Figure 2 As shown, since the upper supporting bowl 11 and the lower supporting bowl 12 are arranged at intervals along the first direction, and the second direction is perpendicular to the first direction, when the first positioning member 2 is placed on one side of the sensor 1 along the second direction, for example, the first positioning member 2 is arranged on the sensor body 13 on the sensor 1 for supporting the lower supporting bowl 12, and the first positioning member 2 can simultaneously abut against the side walls of the upper supporting bowl 11 and the lower supporting bowl 12 on the same side of the second direction, thereby keeping the side walls of the upper supporting bowl 11 and the lower supporting bowl 12 along the second direction parallel to the first direction. At this time, the centers of the bowl sockets of the upper supporting bowl 11 and the lower supporting bowl 12 correspond to each other up and down, and the bowl sockets are curved. Under the action of gravity, the steel ball can stably fall on the center of the bowl socket of the lower supporting bowl 12, thereby keeping the steel ball in the center of the bowl socket of the upper supporting bowl 11 and the lower supporting bowl 12. That is, when the upper supporting bowl 11 and the lower supporting bowl 12 are misaligned, the detection accuracy of the sensor can be adjusted through the first alignment member 2. On this basis, when the first alignment member 2 is arranged on one side of the sensor 1 along the second direction, the second alignment member 3 can be arranged on the other side of the sensor 1 along the second direction. For example, the second alignment member 3 is also placed on the sensor body 13. At this time, the second alignment member 3 can be offset against the first alignment member 2, so as to support the first alignment member 2 along the second direction. The operation is simple and convenient, and the first alignment member 2 can be quickly positioned and stably placed, so as to facilitate the rapid adjustment of the relative misalignment of the upper supporting bowl 11 and the lower supporting bowl 12, thereby effectively improving the adjustment efficiency of the detection accuracy of the sensor 1, and then improving the weighing detection efficiency of the load-carrying transportation equipment.

[0033] It should be noted that, in this embodiment, Figure 1and Figure 2 As shown, the second alignment member 3 is opened relative to the first alignment member 2 , and is symmetrically arranged with respect to the first alignment member 2 in the second direction.

[0034] It should be noted that, in this embodiment, Figure 1 As shown, the cross-sectional shapes of the upper supporting bowl 11 and the lower supporting bowl 12 along the first direction are both circular, that is, the side walls of the upper supporting bowl 11 and the lower supporting bowl 12 along the second direction are both curved surfaces. Correspondingly, the inner wall shape of the first alignment member 2 opening along the second direction can be a curved surface matching the side wall shape of the upper supporting bowl 11 and the lower supporting bowl 12, or can be a curved surface plus a plane, or a plane. It is only necessary to ensure that the inner wall of the first alignment member 2 can abut against the side walls of the upper supporting bowl 11 and the lower supporting bowl 12 along the second direction. For example, Figure 1 As shown, the projection of the first alignment member 2 on the XY plane can be a "C" shape, a laid-down "U" shape, or a laid-down concave shape.

[0035] Optionally, the second alignment member 3 is extended along the first direction and is opened relative to the first alignment member 2. When the second alignment member 3 and the first alignment member 2 are respectively arranged on both sides of the sensor 1 along the second direction, the inner wall of the second alignment member 3 is against the side wall of the upper bowl 11 along the second direction and the side wall of the lower bowl 12 along the second direction.

[0036] In this embodiment, if Figure 1 and Figure 2 As shown, the second alignment member 3 and the first alignment member 2 are arranged with an opening opposite to each other, and are extended along the first direction at the same time. When the second alignment member 3 and the first alignment member 2 are respectively arranged on both sides of the sensor 1 along the second direction, that is, when the second alignment member 3 is abutted against the first alignment member 2, the inner wall of the second alignment member 3 can also be abutted against the side wall of the upper supporting bowl 11 along the second direction and the side wall of the lower supporting bowl 12 along the second direction, that is, the first alignment member 2 and the second alignment member 3 are abutted against each other to form a limiting structure arranged in a rotating body around the circumference of the lower supporting bowl 12 and the upper supporting bowl 11, so that the first alignment member 2 and the second alignment member 3 only need to complete the abutment to ensure that the centers of the bowl nests of the upper supporting bowl 11 and the lower supporting bowl 12 correspond to each other up and down along the first direction. The operation is simple and convenient, and the adjustment efficiency of the detection accuracy of the sensor 1 can be further improved.

[0037] It should be noted that, in the present embodiment, the second alignment member 3 and the first alignment member 2 are symmetrically arranged about the center line of the upper supporting bowl 11 and the lower supporting bowl 12. The inner wall shape of the second alignment member 3 opening along the second direction can be a curved surface matching the side wall shape of the upper supporting bowl 11 and the lower supporting bowl 12, or can be a curved surface plus a plane, or a plane. It is only necessary to ensure that the inner wall of the second alignment member 3 and the side walls of the upper supporting bowl 11 and the lower supporting bowl 12 along the second direction can be offset. For example, Figure 1As shown, the projection of the second alignment member 3 on the XY plane can be a "C" shape, a "U" shape that is laid down, or a concave shape that is laid down. Of course, the second alignment member 3 can also be asymmetrically arranged with the first alignment member 2 about the center line of the upper supporting bowl 11 and the lower supporting bowl 12, that is, the projections of the second alignment member 3 and the first alignment member 2 on the XY plane are not the same.

[0038] Optionally, the sensor 1 also includes a sensor body 13, the lower support bowl 12 is arranged on the support surface 131 of the sensor body 13, the first alignment member 2 and the second alignment member 3 are both used to be placed on the support surface 131, and the projection of the inner wall of the first alignment member 2 on the support surface 131 is a curve concave away from the second direction, and at least partially overlaps with the outer contour of the projection of the upper support bowl 11 and the lower support bowl 12 on the support surface 131.

[0039] In this embodiment, if Figure 2 As shown, the sensor 1 is also provided with a sensor body 13 capable of carrying a lower supporting bowl 12. The sensor 1 is arranged below the scale body of the truck scale, and the upper supporting bowl 11 is connected to the bottom wall of the scale body. When the scale body is weighed, the upper supporting bowl 11 is driven by the pressure of the scale body to move toward the lower supporting bowl 12 and clamp the steel ball to transmit pressure to the lower supporting bowl 12, so that the sensing element of the sensor body 13 is finally deformed by force to realize weighing detection. Specifically, a supporting surface 131 is provided on the sensor body 13 for placing the lower supporting bowl 12. When adjusting the sensor 1, the first aligning member 2 and the second aligning member 3 can be placed on the supporting surface 131. The first aligning member 2 and the second aligning member 3 are supported along the first direction by the supporting surface 131, so as to maintain the stability of the first aligning member 2 and the second aligning member 3 when adjusting the detection accuracy of the sensor 1. At the same time, the abutment cooperation of the second aligning member 3 on the first aligning member 2 effectively improves the use stability of the first aligning member 2 and ensures the alignment accuracy of the upper supporting bowl 11 and the lower supporting bowl 12 after adjustment. On this basis, the projection of the inner wall of the first alignment member 2 on the support surface 131 is a curve concave away from the second direction. When the first alignment member 2 abuts against the side walls of the upper support bowl 11 and the lower support bowl 12, the projection of the inner wall of the first alignment member 2 on the support surface 131 can at least partially overlap with the outer contours of the projections of the upper support bowl 11 and the lower support bowl 12 on the support surface 131, thereby effectively improving the contact area between the inner wall of the first alignment member 2 and the upper support bowl 11 and the lower support bowl 12 respectively, and effectively improving the alignment accuracy of the upper support bowl 11 and the lower support bowl 12 during the adjustment process through the inner wall of the first alignment member 2.

[0040] It should be noted that, in this embodiment, Figure 1As shown, the projections of the inner wall and outer wall of the first alignment member 2 along the second direction on the support surface 131 are parallel to each other. In other embodiments of the utility model, the projection of the outer wall of the first alignment member 2 along the second direction on the support surface 131 may also be a straight line or a curve that is not parallel to the projection of the inner wall on the support surface 131.

[0041] Optionally, the first alignment member 2 includes an outer wall panel 21 and an inner wall panel 22 stacked along the second direction, and the inner wall panel 22 is detachably connected to the outer wall panel 21 .

[0042] For the alignment adjustment of the upper supporting bowl 11 and the lower supporting bowl 12 of different types of sensors 1, since the sizes along the second direction are different, in this embodiment, Figure 5 As shown, an outer wall plate 21 and an inner wall plate 22 which can be stacked along the second direction are provided to form a first alignment member 2, and the outer wall plate 21 and the inner wall plate 22 are detachably connected. With this arrangement, when the size of the upper supporting bowl 11 and the lower supporting bowl 12 along the second direction is larger, the sensor 1 can be adjusted solely by using the outer wall plate 21 as the first alignment member 2. Correspondingly, when the size of the upper supporting bowl 11 and the lower supporting bowl 12 along the second direction is smaller, the thickness of the first alignment member 2 can be increased by stacking the inner wall plate 22 on the outer wall plate 21, so that when the first alignment member 2 is placed on the sensor 1, the inner wall of the inner wall plate 22 along the second direction can respectively abut against the side walls of the upper supporting bowl 11 and the lower supporting bowl 12 along the second direction, thereby realizing rapid adjustment of the sensor 1.

[0043] It should be noted that, in this embodiment, the second alignment member 3 has the same structure as the first alignment member 2, and is also composed of at least two wall panels that can be stacked and detachably connected along the second direction. Of course, in other embodiments of the utility model, the second alignment member 3 can also be an integral structure.

[0044] It should be noted that, in the present invention, the outer wall plate 21 and the inner wall plate 22 can be detachably connected by means of screw connection, snap connection or interlocking connection.

[0045] Optionally, a first clip structure 211 is provided on the wall surface of the outer wall panel 21 facing the inner wall panel 22, and a second clip structure 221 is provided on the wall surface of the inner wall panel 22 facing the outer wall panel 21. The first clip structure 211 is used to correspond to the second clip structure 221 so that the outer wall panel 21 and the inner wall panel 22 can be detachably connected.

[0046] In this embodiment, if Figure 5As shown, a first clip-on structure 211 is provided on the outer wall panel 21 facing the inner wall panel 22. Specifically, the first clip-on structure 211 is a clip-on block. Correspondingly, a second clip-on structure 221 is provided on the wall surface of the inner wall panel 22 facing the outer wall panel 21. Specifically, the second clip-on structure 221 is a clip-on groove. The inner wall panel 22 and the outer wall panel 21 are detachably connected. The first clip-on structure 211 can be correspondingly clipped with the second clip-on structure 221, that is, the clip-on block can be correspondingly placed in the clip-on groove to achieve a detachable connection.

[0047] It should be noted that in other embodiments of the present invention, the first clamping structure 211 can be a clamping groove, and the second clamping structure 221 can be a clamping block. Of course, the matching clamping of the first clamping structure 211 and the second clamping structure 221 can also be the matching of the clamping column and the clamping hole, or the matching of the folding plate and the mounting hole.

[0048] It should be noted that, in the present embodiment, the first clamping structure 211 and the second clamping structure 221 extend to the edges of the outer wall plate 21 and the inner wall plate 22 respectively along the first direction, and are both provided in a plurality and are spaced apart around the first direction. In other embodiments of the present utility model, the first clamping structure 211 and the second clamping structure 221 may also extend to the edges of the outer wall plate 21 and the inner wall plate 22 respectively around the first direction, and are both provided in a plurality and are spaced apart along the first direction.

[0049] Optionally, in the first direction, the size of the outer wall panel 21 is greater than or equal to the size of the inner wall panel 22 .

[0050] For the alignment adjustment of the upper supporting bowl 11 and the lower supporting bowl 12 of different types of sensors 1, since the sizes of the upper supporting bowl 11 and the lower supporting bowl 12 used in combination with different types are different along the second direction, therefore, in this embodiment, Figure 6 As shown, the size of the inner wall plate 22 along the first direction is set to be less than or equal to the size of the outer wall plate 21 along the first direction. With this setting, the inner wall plate 22 can be detachably installed by stacking on the outer wall plate 21, so that the thickness of the first alignment member 2 at different positions along the first direction can be kept consistent or different. In this way, when the sizes of the upper support bowl 11 and the lower support bowl 12 along the second direction are different, the thickness of the first alignment member 2 can be adjusted by disassembling and assembling the inner wall plate 22, so that the inner wall of the first alignment member 2 can simultaneously abut against the side walls of the upper support bowl 11 and the lower support bowl 12 along the second direction.

[0051] It should be noted that, in this embodiment, Figure 6As shown, the size of the inner wall plate 22 along the first direction is one third of the size of the outer wall plate 21 along the second direction, and the inner wall plate 22 is stacked and installed on the upper part of the outer wall plate 21 along the first direction. After the inner wall plate 22 is installed, the thickness of the upper part of the first alignment member 2 along the first direction is equal to twice the thickness of the lower part. Of course, the inner wall plate 22 can also be installed at the lower part of the outer wall plate 21.

[0052] Optionally, the sensor adjustment device further includes an alignment structure 4 , which is mounted on the first alignment member 2 and / or the second alignment member 3 , and the second alignment member 3 is used to be aligned with the first alignment member 2 through the alignment structure 4 .

[0053] In this embodiment, in order to prevent the first alignment member 2 and the second alignment member 3 from being misaligned when they abut against each other, Figure 4 As shown, an alignment structure 4 is provided on the first alignment member 2 and / or the second alignment member 3, and when the first alignment member 2 abuts against the second alignment member 3, the alignment structure 4 can limit the first alignment member 2 and the second alignment member 3 along directions perpendicular to the first direction and the second direction respectively, thereby ensuring the accuracy of the first alignment member 2 and the second alignment member 3 when they abut against each other, and further ensuring the accuracy of the detection accuracy adjustment of the sensor 1.

[0054] It should be noted that, in this embodiment, Figure 4 As shown, both the first alignment member 2 and the second alignment member 3 are provided with an alignment structure 4, which can be a combination of an alignment hole and an alignment column, a combination of an alignment slot and an alignment block, or a combination of a limit groove and a limit block.

[0055] Optionally, the alignment structure 4 includes an alignment port 41 and an alignment block 42, the opening direction of the alignment port 41 is parallel to the second direction, the alignment port 41 and the alignment block 42 are respectively arranged on the first alignment member 2 and the second alignment member 3 or on the second alignment member 3 and the first alignment member 2, and the alignment block 42 is used to be placed in the alignment port 41; and / or, the alignment structure 4 includes a limit block 43, the limit block 43 is arranged on the outer wall of the first alignment member 2 along the third direction and / or on the outer wall of the second alignment member 3 along the third direction, the third direction is perpendicular to both the first direction and the second direction, when the first alignment member 2 and the second alignment member 3 abut against each other, the limit block 43 covers and fits the abutment between the first alignment member 2 and the second alignment member 3.

[0056] In this embodiment, if Figure 4As shown, an alignment port 41 and an alignment block 42 are provided to form an alignment structure 4, wherein the opening direction of the alignment port 41 is parallel to the second direction, and when the first alignment member 2 and the second alignment member 3 cooperate and abut against each other, the alignment block 42 can be correspondingly placed in the alignment port 41, thereby limiting the first alignment member 2 and the second alignment member 3 to ensure the alignment accuracy. Specifically, the alignment port 41 and the alignment block 42 can be respectively provided on the first alignment member 2 and the second alignment member 3. Of course, the alignment port 41 and the alignment block 42 can also be respectively provided on the second alignment member 3 and the first alignment member 2, or the first alignment member 2 and the second alignment member 3 are both provided with the alignment port 41 and the alignment block 42.

[0057] It should be noted that, in this embodiment, the alignment opening 41 and the alignment block 42 are both extended along the first direction.
