Description

Technical Field

[0001] This utility model relates to the field of steel plate production and inspection technology, and in particular to a double-layer weighing vehicle for steel plate inspection and collection. Background Technology

[0002] In the collection process of hot-rolled medium and heavy plates, the steel plates typically require a magnetic crane to lift them from the roller conveyor to a stacking platform for final storage. This ensures the edges of the plates are neatly stacked. During stacking, quality control personnel periodically inspect the surface and dimensions of the plates. Once a certain quantity of plates is stacked, an overhead crane lifts them from the stacking platform to a weighing truck for weighing and storage. Because the weighing operation is performed by a separate truck, the plates cannot be removed from the production line in a timely manner, affecting the normal production of steel plates on the entire line. Therefore, to address the issues of quickly inspecting the surface and dimensions of steel plates and efficiently storing them during collection, thus reducing operational steps, a double-layer weighing truck for steel plate inspection and collection has been developed. Utility Model Content

[0003] The purpose of this invention is to provide a double-layer weighing vehicle for the inspection and collection of steel plates, thereby solving the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a double-layer weighing cart for inspecting and collecting steel plates, comprising an upper weighing cart, a lower weighing cart disposed below the upper weighing cart, and two inspection platforms symmetrically disposed on the outer sides of the upper weighing cart; the bottom height of the platform of the upper weighing cart is higher than the height of the lower weighing cart, and the distance between the two side panels of the upper weighing cart is greater than the width of the lower weighing cart; a width stop and a length stop are fixedly disposed on the upper part of the platform of both the upper and lower weighing carts, the width stop and the length stop are perpendicularly disposed, a length measuring scale is fixedly disposed on the outer side of the width stop, and a width measuring scale is fixedly disposed on the outer side of the length stop.

[0006] Furthermore, the bottom of both sides of the upper and lower weighbridges are symmetrically equipped with two sets of wheels, and each of the upper and lower weighbridges is equipped with a motor for driving the corresponding wheels to rotate.

[0007] Furthermore, each of the aforementioned testing platforms is equipped with a ladder at both ends of its outer side.

[0008] Furthermore, multiple support blocks are fixedly installed at even intervals on the platform panels of the upper and lower weighbridges, respectively.

[0009] Furthermore, the upper and lower weighbridges are each fixedly provided with multiple limiting stops that are flush with the width stops at even intervals on their respective platform panels.

[0010] Furthermore, each of the length measuring scales and each of the width measuring scales is slidably fitted with a scale slide, and each scale slide is provided with a reading plate with an L-shaped cross section. The horizontal part of the reading plate is connected to the scale slide, and the vertical part of each reading plate is used to abut against the edge of the steel plate to be measured.

[0011] Furthermore, each of the scale slides is symmetrically fixed with two vertical connecting rods on its upper part. A connecting plate is fixedly mounted on the upper end of the two connecting rods. A screw is rotatably mounted between the connecting plate and the upper part of the scale slide. The upper end of the screw extends above the connecting plate and is fixedly mounted with a knob for driving its rotation. One end of the scale reading plate is provided with a threaded hole that matches the screw, and two smooth through holes that slide and engage with the two connecting rods respectively.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] In this invention, when stacking steel plates on the upper and lower weighing carts, the length of the steel plates is ensured to be aligned by a length stop, and the width of the steel plates is ensured to be aligned by a width stop. After the steel plates are placed, quality inspection personnel can check whether the width of the steel plates meets the standard requirements using a width measuring ruler on the inspection platform, and check the actual length of the steel plates using a length measuring ruler. Therefore, this invention can ensure the neatness of the steel plates stacked on the weighing cart, facilitate the dimensional inspection of the steel plates, and help ensure the accuracy of dimensional measurements.

[0014] In addition, the upper and lower weighbridges can work alternately to avoid the situation where steel plates cannot be unloaded from the roller conveyor due to waiting for the weighbridge, which can improve the efficiency of steel plate collection and reduce the waiting time for collection.

[0022] Example 1

[0023] like Figures 1-3 As shown, a double-layer weighing vehicle for inspecting and collecting steel plates includes an upper weighing vehicle 1, a lower weighing vehicle 2 located below the upper weighing vehicle 1, and two inspection platforms 3 symmetrically arranged on the outside of the upper weighing vehicle 1.

[0024] The bottom height of the platform of the upper weighbridge 1 is higher than the height of the lower weighbridge 2, and the distance between the two side panels of the upper weighbridge 1 is greater than the width of the lower weighbridge 2, so that the lower weighbridge 2 can pass normally under the upper weighbridge 1, realizing the reciprocating alternating operation of the two.

[0025] Two sets of wheels 4 are symmetrically mounted on the bottom of each side of the upper weighbridge 1 and the lower weighbridge 2. Each of the upper and lower weighbridge 1 is equipped with a motor 5 to drive the corresponding wheel 4 (the motor of the upper weighbridge 1 is not shown, but those skilled in the art can install it according to the description). By driving the corresponding wheels with the motors, the upper and lower weighbridges can move on the ground. Furthermore, the workshop floor is equipped with tracks that are adapted to the two sets of wheels of the upper weighbridge 1 and the two sets of wheels of the lower weighbridge 2, thereby ensuring the stability of their movement.

[0026] Both the upper weighbridge 1 and the lower weighbridge 2 are fixedly equipped with a width stop 6 and a length stop 7 on their upper platforms. The width stop 6 and the length stop 7 are arranged perpendicularly. A length measuring scale 8 is fixedly installed on the outer side of the width stop 6, and a width measuring scale 9 is fixedly installed on the outer side of the length stop 7.

[0027] In addition, multiple support blocks 10 are fixedly and evenly spaced on the platform panels of the upper weighbridge 1 and the lower weighbridge 2, respectively, to support the steel plates placed on the weighbridge platform panels. Multiple limiting stops 11, flush with the width 6 stops, are also fixedly and evenly spaced on the platform panels of the upper weighbridge 1 and the lower weighbridge 2. Because the steel plates are relatively long, the multiple limiting stops 11 further ensure the straightness of the steel plates.

[0028] Each of the inspection platforms 3 has a ladder 12 installed at both ends of its outer side. The ladder 12 facilitates the movement of staff up and down the inspection platform. The upper part of the inspection platform 3 is fixedly equipped with a guardrail 24 to ensure safety.

[0029] In this embodiment, during operation, the overhead crane 13 drives the magnetic hoist 14 to transfer the steel plates 16 on the roller conveyor 15 to the platform of the upper weighing cart 1 or the lower weighing cart 2. When workers are stacking the steel plates, the length head of the steel plate is blocked by the length stop 7 to ensure that the length direction is neat, and the side of the steel plate is blocked by the width stop 6 to ensure that the width direction is neat. After the steel plates are placed, the quality inspection personnel can reach the inspection platform 3 via the ladder 12 and approach the platform of the weighing cart through the platform extension. Afterwards, they can check whether the width of the steel plate meets the standard requirements by using the width measuring ruler and check the actual length of the steel plate by using the length measuring ruler. After the steel plates are stacked neatly, the upper weighing cart can reach the weighing area along its corresponding track, and similarly, the lower weighing cart can also reach the weighing area along its corresponding track. In addition, the upper and lower weighing carts can work alternately, avoiding the situation where the steel plates cannot be unloaded from the roller conveyor due to waiting for the weighing cart, which can improve the efficiency of steel plate collection and reduce the waiting time.

[0030] Example 2

[0031] This embodiment improves the structure of the length measuring scales 8 and width measuring scales 9 of the platform panels 17 of the upper and lower weighbridges without changing the other structures of Embodiment 1. For example... Figures 4-5 As shown, each of the length measuring scales 8 and width measuring scales 9 is slidably fitted with a scale slide 18. Each scale slide 18 is provided with an L-shaped reading plate 19. The horizontal part of the reading plate 19 is connected to the scale slide 18, and the vertical part of each reading plate 19 is used to abut against the edge of the steel plate to be measured. In this example, when measuring the size of the steel plate, the scale slides 18 on the length measuring scales 8 and width measuring scales 9 can be slid until the lower end of the vertical part of the reading plate 19 corresponding to the scale slide 18 abuts against the edge of the steel plate to be measured. Then, the operator can read the value through the contact position between the scale slide 18 and the measuring scale, thereby improving the convenience of measuring the size of the steel plate.

[0032] In addition, two vertical connecting rods 20 are symmetrically fixedly arranged on the upper part of each of the scale slides 18, and a connecting plate 21 is fixedly arranged on the upper end of the two connecting rods 20. A vertical screw 22 is rotatably installed between the connecting plate 21 and the upper part of the scale slide 18. The upper end of the screw 22 extends above the connecting plate 21 and is fixedly installed with a knob 23 for driving its rotation. The horizontal part of the reading plate 19 has a threaded hole adapted to the screw 22 near its end, and two smooth through holes that slide with the two connecting rods 20 respectively. In this embodiment, the screw 22 is rotated by rotating the knob 23. When the screw rotates, the reading plate maintains the threaded connection with the screw, thereby causing the reading plate to move in a vertical linear motion, realizing the adjustment of the height of the vertical part of the reading plate, so that it can abut against the edge of steel plates with different stacking heights. Furthermore, the height of the knob 23 on the lower weighbridge is lower than the bottom height of the platform of the upper weighbridge, thereby avoiding interference with the normal passage of the lower weighbridge on the upper weighbridge.

[0033] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
