Description

Technical Field

[0001] The utility model relates to the technical field of material handling equipment, in particular to steel pipe material handling equipment. Background Art

[0002] In a steel processing factory, steel pipes are one of the common raw materials and usually need to be stacked and transported. After the transport vehicle arrives at the factory, a hoisting device is used to hoist and load the steel pipes. Through the clamping and conveying method, the hoisting device can stably transport the steel pipes to the required storage position and can also be used for the loading and unloading of steel pipes. Using the hoisting device for clamping and conveying can quickly and stably move a large number of steel pipes, saving labor costs and reducing the handling time.

[0003] However, the stacked steel pipes are often not very neat, and the scattered steel pipes are very easy to slide off from both sides, resulting in damage to the pipe materials. There is also a risk that the staff may be injured. The loaded steel pipes also have the problem of being scattered and need secondary material handling, increasing the labor. Therefore, we propose a steel pipe material handling device to solve the existing problems. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a steel pipe material handling device for the problems existing in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A steel pipe material handling device, including a mounting seat, a clamping structure and a correction structure. The clamping structure includes a first rotating shaft and a second rotating shaft rotatably installed inside the mounting seat, a first motor located at the upper end of the mounting seat, a driving gear one fixed to the output end of the first motor, a driven gear one sleeved on the outer wall of the first rotating shaft, a driven gear two sleeved on the outer wall of the second rotating shaft, a first clamping plate and a second clamping plate fixed to both ends of the first rotating shaft and the second rotating shaft.

[0006] The correction structure includes hydraulic rods symmetrically distributed inside the mounting seat, a stroke frame located at the upper end of the telescopic end of the hydraulic rod, a bearing embedded inside the stroke frame, a screw rod rotatably inserted inside the bearing, correction plates located on both sides of the mounting seat, a connecting plate located at the upper end of the correction plate, a threaded hole opened inside the connecting plate and rotatably sleeved on the outer wall of the screw rod, a second motor fixed inside the stroke frame, an output gear fixed to the output end of the second motor, and a transmission gear sleeved on the outer wall of the screw rod and meshing with the output gear.

[0007] When using the steel pipe management equipment in this solution, the lifting ring at the upper end of the lifting frame is connected to the lifting device. During use, the first clamping plate and the second clamping plate are in an open state. When descending to the outside of the steel pipe, the first motor operates to drive the driving gear to rotate. Since the driving gear rotates with the first driven gear, it pushes the first driven gear to rotate. Since the first driven gear rotates with the second driven gear, it pushes the second driven gear to rotate. The first rotating shaft and the second rotating shaft achieve relative rotation, driving the first clamping plate and the second clamping plate to rotate relatively, clamping the stacked steel pipes, and then transporting them through the lifting device. Moreover, both the first clamping plate and the second clamping plate are in two groups, providing a large bearing surface for the bottom of the steel pipes.

[0008] Before transportation, the hydraulic rod drives the stroke frame to descend, driving the correction plate to descend. The second motor drives the output gear to rotate, and the output gear pushes the transmission gear to rotate, driving the screw rod to rotate. Since the connecting plate slides on the outer wall of the guide rod through the sliding sleeve, the screw hole inside the connecting plate is pushed when the screw rod rotates, and the correction plate moves relatively, squeezing the two ends of the steel pipe, and the steel pipe moves towards the center of the clamping structure, making the stacked steel pipes held neatly, and at the same time limiting the two ends of the steel pipe stack.

[0009] Preferably, a lifting frame is provided at the upper end of the mounting seat, and a lifting ring is provided at the upper end of the lifting frame. The lifting frame is connected to the lifting device through the lifting ring to be driven by the lifting device.

[0010] Preferably, the lifting frame includes a top plate and support feet, and the support feet are located at the four corners of the lower end of the top plate and are connected to the four corners of the upper end of the mounting seat at the bottom. The lifting frame is sleeved on the side of the mounting seat through the support feet, enabling the effective use of the correction structures such as the screw rod and the second motor, and providing a longitudinal stroke space for them.

[0011] Preferably, a sliding sleeve is embedded in the stroke frame, and a guide rod with one end fixedly connected to the stroke frame is slidably inserted into the sliding sleeve. The connecting plate slides on the outer wall of the fixedly installed guide rod through the sliding sleeve to obtain sliding guidance.

[0012] Preferably, the threads on the outer wall of the screw rod are distributed relatively, and limit rings are provided at both ends of the screw rod. The limit rings prevent the screw hole from completely disengaging from the screw rod.

[0013] Preferably, the driving gear meshes with the first driven gear, and the first driven gear meshes with the second driven gear. When the driving gear rotates, it pushes the first driven gear to rotate, and then pushes the second driven gear to rotate.

[0014] Preferably, a stroke groove is provided inside the first clamping plate, and one end of the second clamping plate is rotatably installed inside the stroke groove. When the second clamping plate rotates relative to the first clamping plate, the stroke groove provides stroke compensation for the second clamping plate to ensure that it can still be clamped tightly when clamping a small number of steel pipes.

[0015] Preferably, rubber pads are provided at opposite ends of the correction plate. When the correction plate pushes against both ends of the steel pipe, it makes flexible contact with both ends of the steel pipe to avoid scratching damage to it.

[0016] Preferably, a pressing structure is provided at the lower end of the mounting seat. The pressing structure includes electric push rods symmetrically distributed inside the mounting seat, a pressing frame located at the lower end of the electric push rods, springs at the four corners at the lower end of the pressing frame, and a pressing plate fixed to the lower ends of the springs. Both the pressing frame and the pressing plate are located between the first clamping plate and the second clamping plate, and a storage groove is provided inside the lower end of the mounting seat. The electric push rods drive the pressing frame and the pressing plate to descend, and press the clamped steel pipe from top to bottom, making the clamped steel pipe more stable.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. The clamping structure of the lifting device of the present utility model is provided with two groups. When the steel pipe is clamped, it is supported at the bottom in two positions, improving the stability during transportation. At the same time, correction plates that can move longitudinally and relatively are provided on both sides of the clamping structure to relatively squeeze and align both ends of the steel pipe during the clamping and transportation process, and both ends are limited and fixed. During the transfer process, the steel pipe is prevented from falling, reducing the problems of shaking and slipping of the steel pipe during transportation, thereby reducing the risk of workers being injured by being hit, and the conveying process is sorted and processed, making the conveying more stable and safe.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 - 6 shown, the steel pipe material handling equipment proposed by the present invention includes a mounting base 100, a clamping structure 200 and a straightening structure 300. The clamping structure 200 includes a first rotating shaft 203 and a second rotating shaft 204 rotatably installed inside the mounting base 100, a first motor 201 located at the upper end of the mounting base 100, a driving gear 202 fixedly disposed at the output end of the first motor 201, a first driven gear 205 sleeved on the outer wall of the first rotating shaft 203, a second driven gear 206 sleeved on the outer wall of the second rotating shaft 204, a first clamping plate 207 and a second clamping plate 208 fixedly disposed at both ends of the first rotating shaft 203 and the second rotating shaft 204;

[0032] A lifting frame 101 is provided at the upper end of the mounting base 100, and a lifting ring 102 is provided at the upper end of the lifting frame 101;

[0033] The lifting frame 101 includes a top plate and support feet, and the support feet are located at the four corners of the lower end of the top plate and are connected to the four corners of the upper end of the mounting base 100 at the bottom;

[0034] The driving gear 202 meshes with the first driven gear 205, and the first driven gear 205 meshes with the second driven gear 206;

[0035] A stroke groove 209 is formed inside the first clamping plate 207, and one end of the second clamping plate 208 is rotatably installed inside the stroke groove 209;

[0036] Implementation steps based on Embodiment 1: During the working process, the first clamping plate 207 and the second clamping plate 208 are in an open state and are sleeved outside the steel pipe. When the first clamping plate 207 and the second clamping plate 208 rotate relative to each other, the stacked steel pipes are clamped. Both the first clamping plate 207 and the second clamping plate 208 are provided in two groups, which can provide a larger bottom bearing area, thereby more effectively supporting and protecting the steel pipe, reducing deformation and loss.

[0037] As Figures 1 - 6 As shown, compared with Embodiment 1, the steel pipe sorting equipment proposed by the present utility model further includes: The correction structure 300 includes hydraulic rods 303 symmetrically distributed inside the mounting base 100, a stroke frame 304 at the upper end of the telescopic end of the hydraulic rod 303, a bearing 306 embedded inside the stroke frame 304, a screw rod 308 rotatably inserted inside the bearing 306, correction plates 310 on both sides of the mounting base 100, a connecting plate 311 at the upper end of the correction plate 310, a threaded hole 312 opened inside the connecting plate 311 and rotatably sleeved on the outer wall of the screw rod 308, a second motor 301 fixed inside the stroke frame 304, an output gear 302 fixed at the output end of the second motor 301, and a transmission gear 307 sleeved on the outer wall of the screw rod 308 and meshing with the output gear 302;

[0038] A sliding sleeve 309 is embedded and installed inside the stroke frame 304, and a guide rod 305 with one end fixedly connected to the stroke frame 304 is slidably inserted inside the sliding sleeve 309;

[0039] The threads on the outer wall of the screw rod 308 are distributed relatively, and limit rings 313 are provided at both ends of the screw rod 308;

[0040] Rubber pads are provided at the opposite ends of the correction plates 310;

[0041] In this embodiment, before transportation, the hydraulic rod 303 drives the stroke frame 304 to descend, driving the correction plate 310 to descend. At the same time, the second motor 301 drives the output gear 302 to rotate. Through the transmission of the output gear 302, the transmission gear 307 is pushed to rotate, driving the screw rod 308 to rotate. Through the sliding sleeve 309 on the guide rod 305, the connecting plate 311 is moved. Under the push of the screw rod 308, the relative movement of the correction plates 310 is realized, an extrusion effect is applied to both ends of the steel pipe, and the steel pipe is moved to the center of the clamping structure 200, making the clamped steel pipe stack neat and orderly, and limiting the steel pipe stack, avoiding directly clamping and transporting the steel pipe stack by a hoisting device. The steel pipe is very easy to slide off from both sides, resulting in damage to the pipe material, and there is also a risk that the staff will be injured. The steel pipes loaded on the vehicle also have the problem of being scattered and need to be sorted again, increasing the labor. Through automatic sorting, the need for secondary manual sorting is reduced, and the labor cost is reduced.

[0042] As Figures 1 - 6As shown in the figure, compared with the first embodiment, the steel pipe management equipment proposed by the present utility model further includes: a pressing structure 400 is provided at the lower end of the mounting seat 100. The pressing structure 400 includes electric push rods 401 symmetrically distributed inside the mounting seat 100, a pressing frame 403 at the lower end of the electric push rods 401, springs 404 at the four corners at the lower end of the pressing frame 403, and a pressing plate 405 fixed at the lower end of the springs 404. Both the pressing frame 403 and the pressing plate 405 are located between the first clamping plate 207 and the second clamping plate 208, and a storage groove 402 is formed inside the lower end of the mounting seat 100.

[0043] In this embodiment, when clamping the steel pipe, the pressing plate 405 and the pressing frame 403 are located below the base, and the horizontal height is below the first driven gear 205, to limit the clamped steel pipe and prevent the steel pipe from contacting the first driven gear 205 or the second driven gear 206. After the steel pipe is clamped, the electric push rod 401 operates to drive the pressing frame 403 downward, driving the pressing plate 405 to press the upper end of the steel pipe. During the pressing process, the spring 404 is stressed and contracts, while maintaining the pressing force of the pressing plate 405 on the upper end of the steel pipe, avoiding the situation that the steel pipe is damaged due to excessive pressing force, making the transportation of the steel pipe more stable. After use, the pressing plate 405 and the pressing frame 403 in the pressing structure 400 are stored in the storage groove 402 for convenient next use.

[0044] The above specific embodiments are merely several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0045] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
