Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe processing, and more specifically, to anti-deviating conveying equipment suitable for special steel pipe processing. Background Art

[0002] Special steel pipes are steel pipes with special properties and characteristics that are made by adding alloy elements or using special processes on the basis of general steel pipes. These special properties include high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance and good thermal stability. In steel pipe processing plants, most of them use steel pipe conveyor racks to convey annealed steel pipes, and then sort and pack them after conveying them to the designated location, so the conveying equipment plays a vital role;

[0003] In the round steel pipe conveyor disclosed in the patent document with publication number CN204508059U, the steel pipe is conveyed from one end of the steel pipe conveying frame to the other end, and then collected after a material unloading action; however, there is no unloading device involved, and the steel pipes need to be filled in the loading frame before they can be packaged. In this transportation mode, the transportation of steel pipes is discontinuous;

[0004] According to the patent document with the publication number CN206345320U, steel pipes are collected in two adjacent supports, and steel pipes are placed alternately in multiple placement areas. The steel pipes are collected by placing and lifting at the same time, so as to achieve the effect of continuous collection of steel pipes. However, since no limiting structure is set during the transportation of steel pipes, the steel pipes are inevitably offset during transportation, and it is impossible to prevent the steel pipes from offsetting during transportation. Moreover, when the steel pipes are unloaded, the steel pipes are prone to collision due to gravity or impact, and it is impossible to perform double buffering and interception on the steel pipes to reduce the probability of damage caused by collision.

[0005] In view of the above technical defects, a solution is now provided. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-deviation conveying device suitable for processing special steel pipes.

[0013] Furthermore, the tops of the two lifting plates are rotatably connected to a top plate, a cross roller is rotatably provided above the top, both sides of the cross roller are fixedly connected to an L plate, and the bottom of the L plate is slidably matched with the connecting bracket.

[0014] Furthermore, the transmission assembly includes a lower gear fixedly connected to the bottom wall of the driving shaft, the outer side of the lower gear is meshingly connected with a tooth plate, and two adjacent tooth plates are fixedly connected via a connecting plate.

[0015] Furthermore, a second cylinder is fixedly connected to the bottom side wall of the connecting bracket, and an output end of the second cylinder is fixedly connected to a tooth plate close thereto, and the tooth plate is slidably matched with the connecting bracket.

[0016] Furthermore, a middle portion of the tooth plate away from the second cylinder is slidably connected to a limiting shaft, and the limiting shaft is fixedly connected to the frame.

When the inclined plate and buffer plate 1 and buffer plate 2 descend synchronously, the special steel pipe is first intercepted by buffer plate 2 and then conveyed to the bottom of the conveying steel plate for processing in the next step. By intercepting the special steel pipe twice during the unloading process, the impact of its descent is reduced, and the damage caused by its collision is reduced.

[0022] 3. The present invention controls the rotation of the driving shaft to drive the moving plate above the two racks to move closer to each other, and the lifting plate pushes the top plate upward to increase the height of the cross roller, so as to realize the transportation of special steel pipes of different diameters and prevent them from being offset during the transportation process; and then the connecting plate is pushed upward by the cylinder 1, so that the vertical plate and the buffer plate 1 and the buffer plate 2 move upward synchronously, and the special steel pipe is intercepted twice, thereby reducing the impact of the special steel pipe falling and reducing the damage caused by the collision. From the perspective of transportation and unloading, the stable operation of the special steel pipe production line is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: Figure 1-8 As shown, the anti-deviating conveying equipment suitable for special steel pipe processing proposed in this embodiment includes a frame 4 and a conveying steel plate 1 obliquely installed on the top thereof, a conveying mechanism 3 for conveying the steel pipe is arranged on one side of the frame 4, and a buffering unloading mechanism 2 for unloading the steel pipe is arranged below the conveying steel plate 1;

[0034] It should be explained that: a groove is provided above the conveying steel plate 1 for movement of the buffer plate 1 26 and the buffer plate 2 27;

[0035] like Figure 1-8 As shown, the conveying mechanism 3 includes a connecting bracket 33 fixedly connected to the frame 4, an adjusting component 34 for adjusting the conveying size of the steel pipe is arranged above the connecting bracket 33, and a transmission component 35 is arranged below the connecting bracket 33;

[0036] like Figure 3-4 As shown in Figures 6 and 7, the adjustment assembly 34 includes a driving shaft 342 rotatably connected to the connecting bracket 33. The driving shaft 342 is fixedly connected to an upper gear 341 on the outer wall above the connecting bracket 33. Both sides of the upper gear 341 are meshedly connected to a rack 1 343. A limit bar 344 is slidably provided at the bottom of the rack 1 343. The limit bar 344 is fixedly connected to the connecting bracket 33.

[0037] It should be noted that only one end of the movable plate 1 345 is fixedly connected to the rack 1 343, and the other end thereof is located above and in contact with the other rack 1 343, so that when the two racks 1 343 move, the two movable plates 1 345 move closer to or farther from each other, thereby transporting special steel pipes of different diameters.

[0038] like Figure 3-4 As shown in , 6, a moving plate 345 is fixedly connected to the top of the rack 343, and the two moving plates 345 are arranged parallel to each other. Two groups of vertical rollers are rotatably arranged above the moving plate 345, and the two groups of vertical rollers are symmetrically arranged relative to the midline of the moving plate 345. A lifting plate 346 is rotatably arranged in the middle of the moving plate 345, and a top plate 348 is rotatably connected to the tops of the two lifting plates 346. A transverse roller 347 is rotatably arranged above the top, and L plates 349 are fixedly connected to both sides of the transverse roller 347, and the bottom of the L plate 349 is slidably matched with the connecting bracket 33;

[0039] It is necessary to add that the main purpose of the sliding cooperation between the L plate 349 and the connecting bracket 33 is to improve the stability of the top plate 348 when it is raised or lowered;

[0040] The upper gear 341 rotates, driving the moving plate 345 above the two racks 343 to move closer to each other. At the same time, the lifting plate 346 pushes the top plate 348 upward to increase the height of the horizontal roller 347 and reduce the distance between the two vertical rollers. The above steps can realize the transportation of special steel pipes of different diameters, and the special steel pipes are limited by the vertical rollers during the transportation process to prevent them from being offset and falling during the transportation process.

[0041] like Figure 5-6 As shown, the transmission assembly 35 includes a lower gear 354 fixedly connected to the bottom wall of the driving shaft 342, and the outer side of the lower gear 354 is meshedly connected with a tooth plate 352, and two adjacent tooth plates 352 are fixedly connected through a connecting plate 353, and a cylinder 2 351 is fixedly connected to the bottom side wall of the connecting bracket 33, and the output end of the cylinder 2 351 is fixedly connected to a tooth plate 352 close to it, and the tooth plate 352 is slidably matched with the connecting bracket 33; the connecting plate 353 serves to connect multiple tooth plates 352, and multiple groups of tooth plates 352 move synchronously;

[0042] Then the control cylinder 2 351 is extended, driving the plurality of tooth plates 352 to mesh with the lower gear 354, thereby realizing the rotation of the drive shaft 342;

[0043] It should be supplemented here that: a tooth plate 352 away from the second cylinder 351 is slidably connected to a limit shaft in the middle, and the limit shaft is fixedly connected to the frame 4 to improve the stability of the tooth plate 352 during movement;

[0044] In this embodiment, by controlling the extension of the second cylinder 351, the lifting plate 346 pushes the top plate 348 upward, thereby increasing the height of the horizontal roller 347 and reducing the distance between the two vertical rollers, the special steel pipes of different diameters can be transported, and the special steel pipes are limited by the vertical rollers during the transportation process to prevent them from being offset during the transportation process;

[0045] Embodiment 2: Figure 1 , 6 -8, the anti-deviating conveying equipment suitable for special steel pipe processing proposed in this embodiment is improved on the basis of embodiment 1, and in this embodiment, it is used to solve the problem that when the steel pipe is unloaded, the steel pipe may collide due to gravity or impact force, causing damage to the steel pipe, and it is impossible to perform double buffering and interception on the steel pipe to reduce the probability of damage caused by collision;

[0046] The buffer unloading mechanism 2 includes a plurality of cylinders 21 installed at the bottom of the frame 4, a connecting plate 22 is fixedly installed on the top of the cylinder 21, a long rod 23 is commonly installed on one side of the plurality of connecting plates 22, a plurality of vertical plates 24 are arranged on the top of the long rod 23, and the top of the vertical plates 24 is movably penetrated to the top of the connecting bracket 33 and a slanted plate 25 is fixedly installed;

[0047] Then the cylinder 1 21 pushes the connecting plate 22 upward, so that the plurality of vertical plates 24 and the inclined plate 25 move upward synchronously, and pushes the special steel pipe on the transverse roller 347 upward, so that the special steel pipe rolls along the inclined surface of the inclined plate 25 toward the conveying steel plate 1;

[0048] It should be noted that the extended end of the second cylinder 351 is extended when conveying small special steel pipes, and the extended end of the second cylinder 351 is contracted when conveying large steel materials. During the extension and contraction of the extended end of the second cylinder 351, the height of the horizontal roller 347 and the distance between the two vertical rollers are adjusted accordingly, thereby increasing the adaptability of the device and ensuring the efficiency of conveying special steel pipes.

[0049] like Figure 1 , 6 -8, a top frame 28 is fixedly arranged on the other side of the multiple groups of connecting plates 22, and a plurality of parallel buffer plates 1 26 and a plurality of parallel buffer plates 27 are fixedly connected above the top frame 28, the tops of the buffer plates 1 26 and 27 are aligned with each other, and the tops of the buffer plates 1 26 and 27 are extended to the top of the conveying steel plate 1;

[0050] Then the cylinder 1 21 pushes the connecting plate 22 upward, so that the vertical plate 24 and the buffer plate 1 26 and the buffer plate 27 move upward synchronously. When the special steel pipe is pushed onto the conveying steel plate 1, the special steel pipe moves downward along the conveying steel plate 1 and is intercepted by the buffer plate 1 26. Subsequently, the extended end of the control cylinder 1 21 is reset. When the inclined plate 25 and the buffer plate 1 26 and the buffer plate 27 descend synchronously, the special steel pipe is first intercepted by the buffer plate 27.

[0051] In this embodiment, when the buffer plate 1 26 and the buffer plate 2 27 are synchronously lowered, the special steel pipe is first intercepted by the buffer plate 2 27 and then transported to the bottom of the conveying steel plate 1 for processing in the next process. By buffering and intercepting the special steel pipe twice during the unloading process, the impact of its descent is reduced, and the probability of damage caused by collision is reduced;

[0052] It can be known from the present invention in combination with the first and second embodiments that: by controlling the driving shaft 342 to rotate, the upper gear 341 rotates, driving the moving plate 345 above the two racks 343 to move closer to each other, and the lifting plate 346 pushes the top plate 348 upward to increase the height of the horizontal roller 347, so that special steel pipes of different diameters can be transported and prevented from being offset during the transportation process;

[0053] Then, the connecting plate 22 is pushed upward by the cylinder 1 21, so that the vertical plate 24 and the buffer plate 1 26 and the buffer plate 2 27 move upward synchronously, and the special steel pipe is intercepted twice, thereby reducing the impact of the special steel pipe falling and reducing the damage caused by the collision. The present invention performs position-limited transportation on the special steel pipe during transportation, and performs double interception and unloading during unloading, thereby ensuring the stable operation of the special steel pipe production line from the perspective of transportation and unloading;

[0054] Working principle:

[0055] Step 1: First, adjust the distance between the two vertical rollers according to the diameter of the special steel pipe, that is, control the extension of the cylinder 2 351 to drive the multiple tooth plates 352 to mesh with the lower gear 354, realize the rotation of the drive shaft 342, and the upper gear 341 rotates to drive the moving plate 1 345 above the two racks 1 343 to move closer to each other. At the same time, the lifting plate 346 pushes the top plate 348 upward to increase the height of the horizontal roller 347 and reduce the distance between the two vertical rollers. Through the above steps, special steel pipes of different diameters can be transported, and the special steel pipes are limited by the vertical rollers during the transportation process to prevent them from being offset during the transportation process.

[0056] Step 2: After the special steel pipe is transported to the designated position, the cylinder 1 21 pushes the connecting plate 22 upward, so that the vertical plate 24 and the buffer plate 1 26 and the buffer plate 2 27 move upward synchronously. When the special steel pipe is pushed onto the conveying steel plate 1, the special steel pipe moves downward along the conveying steel plate 1 and is intercepted by the buffer plate 1 26. Subsequently, the extended end of the cylinder 1 21 is controlled to reset. When the inclined plate 25 and the buffer plate 1 26 and the buffer 2 are synchronously lowered, the special steel pipe is firstly intercepted by the buffer plate 27 and then transported to the bottom of the conveying steel plate 1 for the next process. By intercepting the special steel pipe twice during the unloading process, the impact of its descent is reduced, and the damage caused by its collision is reduced.

[0057] Step three: Install steps one and two in sequence to complete the transportation of special steel pipes; when transporting large-sized steel pipes: the extended end of cylinder two 351 contracts, driving the lower gear 354 to rotate in the opposite direction, and through the drive shaft 342, the upper gear 341 rotates in the opposite direction synchronously, which not only allows the two movable plates one 345 to move away from each other, but also reduces the height of the cross roller 347, making it more suitable for the transportation of large steel pipes, increasing the adaptability of the device when used.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
