Description

Technical Field

[0001] The invention relates to the technical field of pipe processing equipment, and in particular to a pipe unloading rack. Background Art

[0002] Metal pipes are a commonly used metal profile and are widely used in various fields of production and life. The metal pipes produced by metal pipe manufacturers are relatively long (2 to 5 meters, or even longer), which is mainly for the convenience of production and transportation. In the application link, they need to be cut into the required length according to the use requirements. After the metal pipe is cut, it needs to be taken away from the cutting equipment to complete the cutting work. For shorter metal pipes, a collection frame is generally set up to allow the metal pipe to fall directly into the collection frame after being cut. However, for longer metal pipes, they are usually taken down from the cutting equipment manually, which is inefficient and seriously affects the production capacity of metal pipes. There are also hidden dangers of affecting personnel safety. Summary of the invention

[0003] The object of the present invention is to provide a pipe unloading rack to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] The present invention provides a pipe material unloading rack, which comprises:

[0006] A pipe receiving mechanism, comprising a receiving plate, a first driving device for driving the receiving plate to swing up and down, and a second driving device for driving the receiving plate and the first driving device to move forward and backward;

[0007] A pipe placing rack is arranged below the pipe receiving mechanism; the pipe placing rack is recessed downward to form a recess for placing pipes, and the recess is located at the front side of the receiving plate;

[0008] A spring drum connected to the pipe placing rack, and the spring drum can rotate around a left and right horizontal axis;

[0009] A receiving belt is arranged in the recess, and the two ends of the receiving belt are arranged front and back; one end of the receiving belt is connected to the pipe placing rack, and the other end of the receiving belt is connected to the spring reel.

[0010] After the metal pipe is cut, the second driving device drives the receiving plate to move toward the metal pipe to receive the falling metal pipe. Then, the second driving device drives the receiving plate to move toward the recess, thereby completing the safe transfer of the metal pipe from the cutting device to the recess. The first driving device drives the receiving plate to stably receive the metal pipe, and then drives the receiving plate to swing to an inclination, so that the metal pipe falls from the receiving plate to the recess. The first driving device can adjust the inclination angle of the receiving plate to complete the safe connection and unloading of the receiving plate. In addition, a receiving belt is arranged in the recess. When the metal pipe falls from the receiving plate to the receiving belt, the receiving belt is slowly unwound under the action of the spring drum, exerting a better buffering effect and preventing the metal pipe from being damaged by a strong hard collision. The spring drum can not only drive the receiving belt to unwind slowly and stably, but also drive the receiving belt to rewind in an unloaded state to return to its original position.

[0011] As a further improvement of the above technical solution, the receiving plate includes a support plate and a baffle; the baffle is connected to the top surface of the support plate, and the baffle is located at the rear side of the support plate, and the baffle forms an angle with the support plate. The setting of the support plate can play a good supporting role for the metal pipe, and the baffle is set on the support plate. When the support plate is tilted, the baffle can prevent the metal pipe from rolling off the support plate with the help of the blocking effect of the baffle, thereby ensuring the safety of the metal pipe on the receiving plate.

[0012] As a further improvement of the above technical solution, the top surface of the support plate is provided with convex strips; the convex strips are arranged along the length direction of the support plate. The convex strips are arranged on the support plate to reduce the contact area between the receiving plate and the metal pipe, thereby reducing the friction between the metal pipe and the receiving plate, so that the metal pipe can move smoothly and quickly, and complete the work of unloading the pipe efficiently.

[0013] As a further improvement of the above technical solution, the first driving device includes a first telescopic cylinder and a support seat; the support seat is arranged below the receiving plate, and the support seat is hinged to the receiving plate; the first telescopic cylinder is arranged below the receiving plate, and the telescopic end of the first telescopic cylinder is hinged to the receiving plate, and the fixed end of the first telescopic cylinder is hinged to the support seat. When the first telescopic cylinder is working, the receiving plate swings around the hinge between it and the support seat to adjust the inclination angle of the receiving plate, the support seat plays a better supporting role on the receiving plate, and the first telescopic cylinder can make the receiving plate swing faster and more steadily, thereby improving the material discharge efficiency.

[0014] As a further improvement of the above technical solution, the second driving device includes a second telescopic cylinder, a guide rail and a slide; the slide is connected to the support seat; the slide is connected to the guide rail, and the slide can move forward and backward along the guide rail; the guide rail is connected to the pipe placement rack; the telescopic end of the second telescopic cylinder is connected to the support seat, and the fixed end of the second telescopic cylinder is connected to the pipe placement rack. The combination of the guide rail and the slide can not only effectively support the support seat, the receiving plate and the metal pipe on the receiving plate, but also ensure that the support seat can move back and forth quickly and smoothly along the guide rail. The second telescopic cylinder has the advantages of large load and rapid action, and can realize stable and high-speed movement of the support seat.

[0015] As a further improvement of the above technical solution, the pipe unloading rack further includes a gravity block; the gravity block is connected to the receiving belt; the gravity block is located below the receiving belt, and the gravity block is located in the recess. The gravity block is arranged on the receiving belt, and the gravity of the gravity block is utilized to effectively prevent the receiving belt from shaking left and right when receiving the metal pipe, thereby preventing the metal pipe from falling off the receiving belt and being damaged.

[0016] As a further improvement of the above technical solution, the pipe placing rack is provided with a rotating shaft, the two ends of the rotating shaft are arranged horizontally left and right, the spring reel includes a reel and a spring box; the number of the reels is multiple, the multiple reels are arranged at intervals and installed on the rotating shaft; the spring box is equipped with a coil spring inside, and the spring box is installed on the rotating shaft. Arranging multiple reels on the same rotating shaft can drive the multiple reels to rotate synchronously, so that multiple receiving belts can be unwound synchronously, thereby ensuring that the metal pipe falls safely and smoothly under the action of the receiving plate.

[0017] As a further improvement of the above technical solution, the inner wall surface of the recess is inclined outwards, which expands the pipe storage space of the recess.

[0018] As a further improvement of the above technical solution, the second telescopic cylinder is arranged on the left side or right side of the support seat, and the support seat is provided with a connecting portion connected to the telescopic end of the second telescopic cylinder. The second telescopic cylinder is arranged on the left side or right side of the support seat, which can save the manufacturing materials and space occupied by the pipe unloading rack.

[0019] As a further improvement of the above technical solution, a Fuma wheel is provided at the bottom of the pipe placing rack. By providing the Fuma wheel, the fixing, movement and height adjustment of the pipe unloading rack can be achieved.

[0020] Beneficial effects of the invention: The invention provides a pipe unloading rack, which is ingeniously designed, practical and reliable, and can transfer metal pipes from cutting equipment to recessed parts, thereby efficiently and safely completing pipe unloading work.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Reference Figures 1 to 4 , several embodiments of the pipe blanking rack of the present invention are given below.

[0033] like Figures 1 to 4 As shown, an embodiment of the present invention provides a pipe unloading rack, which includes a pipe receiving mechanism 200, a pipe placing rack 100, a spring reel and a receiving belt 300.

[0034] The pipe receiving mechanism 200 includes a receiving plate, a first driving device for driving the receiving plate to swing up and down, and a second driving device for driving the receiving plate and the first driving device to move forward and backward.

[0035] The receiving plate is used to receive and transport the cut metal pipe. The receiving plate includes a support plate 260 and a baffle plate 270. The baffle plate 270 and the top surface of the support plate 260 can be connected by bolt installation, welding or integrated molding process.

[0036] The baffle plate 270 is located at the rear side of the support plate 260, and the baffle plate 270 forms an angle with the support plate 260, which can be an acute angle, a right angle or an obtuse angle. In this embodiment, the angle is greater than 90°, so that the metal pipe can fall onto the support plate 260 along the inclined surface of the baffle plate 270. During the transfer process of the metal pipe, in order to prevent the metal pipe from rolling off the support plate 260 to the ground, the support plate 260 is inclined, and with the blocking effect of the baffle plate 270, the metal pipe can be stably placed on the receiving plate, ensuring the safety of the metal pipe during transfer.

[0037] The support plate 260 and the baffle plate 270 may be made of metal material, which has high strength and rigidity.

[0038] In some embodiments, the top surface of the support plate 260 is provided with a convex strip; the convex strip is arranged along the length direction of the support plate 260. The convex strip can be a cylindrical guide rail. The convex strip is arranged on the support plate 260 to reduce the contact area between the receiving plate and the metal pipe, thereby reducing the friction between the metal pipe and the receiving plate, so that the metal pipe can move smoothly and quickly, and complete the work of unloading the pipe efficiently.

[0039] The first driving device includes a first telescopic cylinder 240 and a support seat 250 .

[0040] The support seat 250 may be in an inverted T shape. The support seat 250 is disposed below the receiving plate, and the top of the support seat 250 is hinged to the receiving plate, so that the receiving plate can rotate clockwise or counterclockwise around the hinge between the support seat 250 and the receiving plate.

[0041] The first telescopic cylinder 240 is disposed below the receiving plate, and the telescopic end (or piston rod) of the first telescopic cylinder 240 is hinged to the receiving plate, and the fixed end (or cylinder body) of the first telescopic cylinder 240 is hinged to the support seat 250. When the telescopic end of the first telescopic cylinder 240 is extended, the receiving plate rotates counterclockwise; when the telescopic end of the first telescopic cylinder 240 is retracted, the receiving plate rotates clockwise. Figure 2 The first telescopic cylinder 240 can adjust the inclination angle of the receiving plate and make the receiving plate swing faster and more stable, thereby improving the material unloading efficiency.

[0042] like Figure 2 As shown, when the pipe is connected, the first telescopic cylinder 240 is operated to rotate the receiving plate clockwise, so that the receiving plate is adjusted from a horizontal state to a slightly inclined state. When the pipe is unloaded, the first telescopic cylinder 240 is operated to rotate the receiving plate counterclockwise, so that the receiving plate is at a greater degree of inclination, so that the metal pipe can roll off the receiving plate.

[0043] The first telescopic cylinder 240 may be a single-axis cylinder.

[0044] Of course, a forward and reverse motor can also be used to replace the first telescopic cylinder 240, a driven gear is set on the hinge shaft between the support seat 250 and the receiving plate, and a driving gear is set on the output shaft of the motor. Through the meshing connection between the driving gear and the driven gear, the motor can drive the receiving plate to rotate clockwise or counterclockwise.

[0045] In addition, a rotary cylinder may be used to replace the combination of the forward and reverse motor, the driving gear and the transmission gear.

[0046] The second driving device includes a second telescopic cylinder 210 , a guide rail 230 and a slide seat 220 .

[0047] The slide 220 is connected to the support seat 250 by screws. In this embodiment, two slides 220 are arranged on the bottom surface of the support seat 250, which can provide strong support for the support seat 250. The slide 220 is slidably connected to the guide rail 230, and the slide 220 can move forward and backward along the guide rail 230.

[0048] The guide rail 230 is connected to the pipe placing rack 100 by screws. One or two guide rails 230 can be arranged on the pipe placing rack 100.

[0049] The telescopic end of the second telescopic cylinder 210 is connected to the support seat 250, and the fixed end of the second telescopic cylinder 210 is connected to the pipe placing rack 100 by bolts. When the telescopic end of the second telescopic cylinder 210 is extended, the support seat 250 can move backward along the guide rail 230 at high speed and stability.

[0050] Specifically, the second telescopic cylinder 210 is disposed on the left or right side of the support base 250, and the support base 250 is provided with a connection portion connected to the telescopic end of the second telescopic cylinder 210. Providing the second telescopic cylinder 210 on the left or right side of the support base 250 can save manufacturing materials and space for the pipe unloading rack.

[0051] Of course, the second telescopic cylinder 210 can also be arranged on the front side or the rear side of the support base 250. However, since the pipe placing rack 100 provides an installation position for the second telescopic cylinder 210, the manufacturing materials and the occupied space of the pipe placing rack 100 will undoubtedly increase.

[0052] The second telescopic cylinder 210 may be a single-axis cylinder.

[0053] Of course, a synchronous belt transmission mechanism and a linear module can be used to replace the combination of the second telescopic cylinder, the guide rail and the slide seat.

[0054] A plurality of pipe receiving mechanisms 200 are arranged on the pipe placing rack 100 to be suitable for the unloading of long pipes.

[0055] The pipe placing rack 100 is arranged below the pipe receiving mechanism 200. The pipe placing rack 100 is recessed downward to form a concave portion for placing pipes, and the concave portion is located at the front side of the receiving plate.

[0056] In some embodiments, the inner wall surface of the recess is inclined outward, that is, in a trumpet shape. Such a design can expand the pipe storage space of the recess.

[0057] Specifically, the pipe placing rack 100 is composed of a plurality of metal connecting rods, and an inclined first connecting rod 110 and a second connecting rod 120 are arranged on the bottom rod located in front of the pipe receiving mechanism 200. The first connecting rod 110 and the second connecting rod 120 are arranged at intervals and form a recess for placing metal pipes. In this embodiment, the pipe placing rack 100 is respectively provided with three first connecting rods 110 and second connecting rods 120. Of course, a bottom plate can be arranged between two adjacent bottom rods.

[0058] The spring drum is connected to the pipe placing rack 100 and can rotate around the left and right horizontal axes. In this embodiment, the spring drum is arranged below the pipe receiving mechanism 200.

[0059] The receiving belt 300 is arranged in the recess, and the two ends of the receiving belt 300 are arranged front and back. One end of the receiving belt 300 is connected to the pipe placing rack 100 through a clamping block, so that one end of the receiving belt 300 is fixed relative to the pipe placing rack 100; the other end of the receiving belt 300 is connected to the spring drum through a clamping block, so that the other end of the receiving belt 300 is fixed relative to the spring drum, so that the receiving belt 300 can be wound and unwound by using the spring drum.

[0060] When the metal pipe falls from the receiving plate to the receiving belt 300, the receiving belt 300 unwinds slowly under the gravity of the metal pipe and the action of the spring drum, which has a better buffering effect on the metal pipe and prevents the metal pipe from being damaged by strong hard collision. The spring drum can not only drive the receiving belt 300 to unwind slowly and steadily, but also drive the receiving belt 300 to rewind in an empty state (that is, there is no metal pipe on the receiving belt) to return to its original position to wait for the next round of metal pipe unloading.

[0061] The receiving belt 300 can be a cloth belt or a belt made of other materials.

[0062] In this embodiment, three pipe receiving mechanisms 200 and four receiving belts 300 are provided to complete the automatic unloading of long pipes.

[0063] In some embodiments, the pipe unloading rack further includes a gravity block 400; the gravity block 400 is connected to the receiving belt 300 through a clamping block, that is, the clamping block is connected to the gravity block and they tightly clamp the receiving belt 300. The gravity block 400 is located below the receiving belt 300, and the gravity block 400 is located in the recess. The gravity block 400 is arranged on the receiving belt 300, and the gravity block 400 is used to effectively prevent the receiving belt 300 from shaking left and right when receiving the metal pipe, thereby preventing the metal pipe from falling from the receiving belt 300 and being damaged.

[0064] The gravity block 400 may be made of metal.

[0065] In some embodiments, the pipe placing rack 100 is provided with a rotating shaft 800, and the two ends of the rotating shaft 800 are arranged horizontally on the left and right sides. The spring reel includes a reel 500 and a spring box; the number of the reels 500 is multiple, and the multiple reels 500 are arranged at intervals and installed on the rotating shaft 800; the spring box is equipped with a coil spring inside, and the spring box is installed on the rotating shaft 800. The coil spring in the spring box drives the rotating shaft 800 to rotate when the receiving belt 300 is unloaded, and the reel 500 also rotates with the rotating shaft 800 to reel the receiving belt 300. A protective cover 700 is also provided to protect the spring box.

[0066] By arranging multiple reels 500 on the same rotating shaft 800, the multiple reels 500 can be driven to rotate synchronously, so that the multiple receiving belts 300 can be unwound and reeled synchronously, thereby ensuring that the metal pipe falls safely and steadily under the action of the receiving plate.

[0067] In some embodiments, the bottom of the pipe rack 100 is provided with a Forma wheel 620, and a support foot pad 610 can be provided at the bottom of the pipe rack 100. The Forma wheel 620 can facilitate the staff to move the pipe unloading rack, adjust its height, or fix it relative to the ground.

[0068] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
