Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to a material handling device for building material storage. Background Technology

[0002] Construction steel is one of the main materials used in building structures, including ordinary steel, low-alloy high-strength steel, high-strength steel, and weathering steel. Commonly used steel materials include steel plates, reinforcing bars, and steel pipes. After steel pipes are purchased and brought back to the factory, they need to be transported to the warehouse by handling equipment and neatly arranged. When steel pipes are needed for use or sale, they are then transported, loaded onto trucks, and shipped.

[0003] When transferring and handling steel raw materials or intermediate products in the shape of round bars or tubes, the steel raw materials or intermediate products are usually stacked. Round bars or tubes are prone to rolling within the handling device. In the existing technology, ropes are often used for binding. However, after the ropes are bound, the knots are prone to loosening, which affects the effect of fixing the steel. After the steel rolls, it is easy to be bumped and damaged, affecting the quality of the steel. Therefore, it is necessary to improve the design of the building material storage and handling device in the relevant technology to reduce the probability of steel rolling. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a handling device for building material storage.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a handling device for building material storage, including a handling trolley, a base plate fixed to the top of the handling trolley, a pad fixed to the top of the base plate, an mounting plate provided on the top of the base plate, and a clamping mechanism provided on the mounting plate for clamping and limiting the two sides of steel stacked on the pad. The clamping mechanism includes an installation assembly, which includes a fixing plate fixed to the top of the mounting plate. Two fixing plates are provided and symmetrically arranged. The installation assembly also includes a guide rod fixed between the two fixing plates and a bidirectional threaded rod rotatably installed between the two fixing plates. The clamping mechanism includes a rod and a motor fixed to one of the fixed plates for driving the bidirectional threaded rod to rotate. The bidirectional threaded rod has two threads with equal pitch and opposite directions. The clamping mechanism also includes a bottom clamping assembly that is jointly arranged on the bidirectional threaded rod and the guide rod for limiting the bottom sides of the stacked steel. The bottom clamping assembly includes two symmetrically arranged movable clamping blocks. The bidirectional threaded rod passes through the movable clamping blocks and is threadedly connected. The guide rod passes through the movable clamping blocks and is slidably engaged. The clamping mechanism also includes a lateral clamping assembly that is arranged on the bottom clamping assembly for limiting the upper sides of the stacked steel.

[0006] By adopting the above technical solution, after a layer of tubular or rod-shaped steel is placed on the pad, the motor needs to be started. After the motor works, it drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to the movable clamping block, and the guide rod is slidably engaged with the movable clamping block, the movable clamping blocks on both sides move closer to each other until the movable clamping blocks on both sides engage and clamp the two sides of the steel, thus completing the limitation of the bottom steel. After other steel is stacked on the lower layer, the upper two sides of the stacked steel can be limited by the lateral clamping component. This changes the traditional design method of using ropes for binding, avoiding the situation where the steel rolls or even gets damaged due to loose knots.

[0007] Furthermore, each of the two movable clamping blocks has an arc surface on one side that is close to the other, and the arc surfaces on both sides abut against the bottom sides of the stacked steel.

[0008] By adopting the above technical solution, the arc surface increases the contact area between the movable clamping block and both sides of the tubular or rod-shaped steel, thereby enhancing the limiting effect on the stacked steel.

[0009] Furthermore, the lateral clamping assembly has two sets symmetrically arranged on the two movable clamping blocks. The lateral clamping assembly includes an L-shaped rod fixed to the top of the movable clamping block. There are two L-shaped rods that are parallel to each other. The lateral clamping assembly also includes a lateral pressure plate hinged between the two L-shaped rods, a connecting rod hinged to the side wall of the lateral pressure plate near its upper end, and a bottom rod hinged to the side wall of the connecting rod near its lower end. The top of the mounting plate is provided with a fixing assembly for fixing the bottom rod.

[0010] By adopting the above technical solution, the bottom rod is pushed and its position on the mounting plate is adjusted. The tilt angle of the side pressure plate can be adjusted by the connecting rod. After the fixing component fixes the bottom rod, the positions of the connecting rod and the side pressure plate are fixed. The side pressure plates on both sides cooperate and limit the stacked steel on both sides respectively, ensuring the stability of the steel during the handling process.

[0011] Furthermore, the fixing assembly includes a C-shaped rod fixed to the top of the mounting plate and a bolt that passes through the bottom rod and is clearance-fitted with the bottom rod. The C-shaped rod has two parts and is symmetrically arranged about the bottom rod. The top of the mounting plate has multiple threaded holes that are threaded to the bolts. Both sides of the bottom rod are integrally formed with protrusions. The top of the protrusions fits into the top of the C-shaped rod, and the bottom of the protrusions fits into the top of the mounting plate.

[0012] By adopting the above technical solution, after the bolts are loosened, the workers push the bottom rod, causing the protrusion on the bottom rod to slide between the top of the C-shaped rod body and the top of the mounting plate. The tilt angle of the side pressure plate can be adjusted by the connecting rod. After the angle of the side pressure plate is adjusted, tightening the bolts can fix the bottom rod, thereby fixing the side pressure plate.

[0013] Furthermore, reinforcing ribs are fixed at the corners of the L-shaped rod.

[0014] By adopting the above technical solution and setting the reinforcing ribs, the structural strength of the L-shaped rod is enhanced, which helps to improve the stability of the connecting rod and the side pressure plate during use.

[0015] Furthermore, the mounting plate is provided with a positioning component for fixing the mounting plate to the base plate. The positioning component includes a pin that passes through the mounting plate and cooperates with the mounting plate, a lifting plate fixed to the upper end of the pin, and a spring sleeved on the pin and fixed between the lifting plate and the mounting plate. The top of the base plate is provided with a plurality of positioning holes that cooperate with the pin. The arrangement direction of the plurality of positioning holes is parallel to the length direction of the base plate.

[0016] By adopting the above technical solution, after pulling the lifting plate and causing the pin to disengage from the positioning hole, the position of the mounting plate on the base plate can be adjusted, thereby adjusting the distance between the mounting plates at both ends of the base plate, and thus adjusting the distance between the two sets of clamping mechanisms, so as to clamp and fix steel of different lengths.

[0017] Furthermore, the intersection between the side wall of the pin and the lower end of the pin is provided with a rounded corner.

[0018] By adopting the above technical solution, the difficulty of aligning the pin and the positioning hole is reduced.

[0019] Furthermore, a dovetail strip is fixed to the bottom of the mounting plate, and a dovetail groove is provided on the top of the base plate to slide with the dovetail strip.

[0020] By adopting the above technical solution, the stability of the mounting plate during the position adjustment process is ensured.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, after a layer of tubular or rod-shaped steel is placed on the pad, the motor needs to be started. After the motor works, it drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to the movable clamping block, and the guide rod is slidably engaged with the movable clamping block, the movable clamping blocks on both sides move closer to each other until the movable clamping blocks on both sides engage and clamp the two sides of the steel, thus completing the limitation of the bottom steel. After other steel is stacked on the lower layer of steel, the upper two sides of the stacked steel can be limited by the lateral clamping component. This changes the traditional design method of using ropes for binding, and avoids the situation where the steel rolls or even damages the steel due to loosening of the knots.

[0023] 2. In this application, by pushing the bottom rod and adjusting its position on the mounting plate, the tilt angle of the side pressure plate can be adjusted by the connecting rod. After the fixing component fixes the bottom rod, the positions of the connecting rod and the side pressure plate are fixed. The side pressure plates on both sides cooperate and limit the two sides of the stacked steel, ensuring the stability of the steel during the handling process.

[0024] 3. In this application, after pulling the lifting plate and causing the pin to disengage from the positioning hole, the position of the mounting plate on the base plate can be adjusted, thereby adjusting the distance between the mounting plates at both ends of the base plate, and thus adjusting the distance between the two sets of clamping mechanisms, so as to clamp and fix steel of different lengths.

The fixing plate 511 is vertically mounted, with its bottom fixed to the top of the mounting plate 4. Two fixing plates 511 are provided and symmetrically arranged. The guide rod 512 is horizontally mounted and fixed between the two fixing plates 511. The two ends of the bidirectional threaded rod 513 are rotatably connected to the two fixing plates 511, and the bidirectional threaded rod 513 has two sections of threads with equal pitch and opposite directions. The motor 514 is fixed on one of the fixing plates 511. The output end of the motor 514 passes through the fixing plate 511 and is rotatably connected. The output end of the motor 514 is fixed to the bidirectional threaded rod 513 and is used to drive the bidirectional threaded rod 513 to rotate.

[0035] The bottom clamping assembly 52 is jointly disposed on the bidirectional threaded rod 513 and the guide rod 512. The bottom clamping assembly 52 includes two movable clamping blocks 7. In this embodiment, each of the two movable clamping blocks 7 has an arc surface 71 on one side that is close to each other. The arc surfaces 71 on both sides abut against the bottom sides of the stacked steel to limit the bottom sides of the stacked steel. The bidirectional threaded rod 513 passes through the movable clamping block 7 and is threadedly connected, while the guide rod 512 passes through the movable clamping block 7 and is slidably engaged.

[0036] The lateral clamping assembly 53 is mounted on the bottom clamping assembly 52. ​​Two sets of the lateral clamping assembly 53 are symmetrically arranged on the two movable clamping blocks 7 to limit the upper sides of the stacked steel. The lateral clamping assembly 53 includes an L-shaped rod 531, a lateral pressure plate 532, a connecting rod 533, and a bottom rod 534. The vertical section of the L-shaped rod 531 is fixed to the top of the movable clamping block 7. Two L-shaped rods 531 are provided and parallel to each other, and a reinforcing rib 8 is fixed at the inner corner of each L-shaped rod 531. The lateral pressure plate 532 is hinged between the two L-shaped rods 531. The upper end of the connecting rod 533 is hinged to the side wall of the lateral pressure plate 532 near its upper end. One end of the bottom rod 534 is hinged to the side wall of the connecting rod 533 near its lower end.

[0037] In this embodiment: Both sides of the base rod 534 near its bottom are integrally formed with protruding strips 5341. The top of the mounting plate 4 is provided with a fixing assembly 9 for fixing the base rod 534. The fixing assembly 9 includes a C-shaped rod 91 and bolts 92. Both ends of the C-shaped rod 91 are fixed to the top of the mounting plate 4. Two C-shaped rods 91 are provided and symmetrically distributed on both sides of the base rod 534. The top of the protruding strip 5341 fits against the inner top of the C-shaped rod 91, and the bottom of the protruding strip 5341 fits against the top of the mounting plate 4. Bolts 92 are inserted through the base rod 534 and have a clearance fit with it. The top of the mounting plate 4 is provided with multiple threaded holes 42 that are threadedly connected to the bolts 92. The arrangement direction of the multiple threaded holes 42 is parallel to the width direction of the base plate 2 (perpendicular to the length direction of the stacked steel).

[0038] The operating principle of the material handling device for building material storage in this embodiment is as follows: After a layer of tubular or rod-shaped steel is placed on the pad 3, the motor 514 needs to be started. After the motor 514 starts working, it drives the bidirectional threaded rod 513 to rotate. Since the bidirectional threaded rod 513 is threadedly connected to the movable clamping block 7, and the guide rod 512 is slidably engaged with the movable clamping block 7, the movable clamping blocks 7 on both sides move closer to each other until the arc surfaces 71 on the movable clamping blocks 7 on both sides abut against the bottom sides of the stacked steel, and then the motor 514 is turned off. At this time, the bolt 92 is pulled out, and the bottom rod 534 can be pushed. In this way, the tilt angle of the side pressure plate 532 can be adjusted by the connecting rod 533 until the side pressure plates 532 on both sides abut against the sides of the stacked steel. Then the bolt 92 is used to fix the bottom rod 534 again. The movable clamping blocks 7 on both sides cooperate with the side pressure plates 532 on both sides and limit the stacked steel, ensuring the stability of the steel during the handling process.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected.
