DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1 Reference Figure 1 and Figure 7 , which is the first embodiment of the present invention, provides a transfer mechanism for small steel pipe production, the device comprising: The conveying mechanism 100 includes a conveying platform 101, an automatic unloading portion 102 disposed on the conveying platform 101, a conveying portion 103 disposed on the conveying platform 101, a buffer portion 104 disposed on the conveying portion 103, a concentric portion 105 disposed on the conveying platform 101, and a temporary storage portion 106 disposed on the concentric portion 105; The transfer vehicle 200 includes a base 201 , a storage portion 202 disposed on the base 201 , a front stop portion 203 disposed on the base 201 , a latch portion 204 disposed on the front stop portion 203 , and a pedaling portion 205 disposed in the base 201 .

[0033] During use, the cut steel pipe falls onto the automatic unloading part 102, the automatic unloading part 102 is tilted, and the steel pipe rolls onto the conveying part 103, and the conveying part 103 conveys the steel pipe to the transfer vehicle 200. When the transfer vehicle 200 is fully loaded, the base 201 is pulled to make the storage part 202 away from the temporary storage part 106, and at the same time, the front stopper 203 drags the steel pipe on the temporary storage part 106 to the storage part 202, so as to transfer the steel pipe; When the fully loaded transfer vehicle 200 is pulled away, the steel pipes transported by the conveying part 103 fall onto the temporary storage part 106, and the empty transfer vehicle 200 is used for the transfer operation. The pedaling part 205 is stepped on to shrink the latch part 204, thereby releasing the limit on the front stop part 203. The front stop part 203 rotates, pushing the empty transfer vehicle 200 to squeeze the concentric part 105. The front stop part 203 gradually stands upright and resets, and at the same time, the steel pipes on the temporary storage part 106 are brought into the transfer vehicle 200 for the next transfer cycle.

[0034] Example 2 Reference Figure 1~Figure 5, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the automatic unloading part 102 includes an unloading shaft 102a rotatably set on the conveying platform 101, an unloading torsion spring 102b fixedly set on the unloading shaft 102a, and an unloading plate 102c fixedly set on the unloading shaft 102a. The unloading plate 102c is set in a U shape to increase the stability of the steel pipe falling into the unloading plate 102c and prevent the steel pipe from falling to the ground. The unloading chute 102d is set on the conveying platform 101. The setting of the unloading chute 102d provides space for the unloading plate 102c to rotate. The setting of the unloading torsion spring 102b not only buffers the steel pipe falling into the unloading plate 102c, but also provides power for the unloading plate 102c to reset.

[0035] The conveying part 103 includes a conveying mounting plate 103a fixedly mounted on the conveying platform 101, a conveying support plate 103b fixedly mounted on the conveying mounting plate 103a, the conveying support plate 103b is tilted to increase the stability of the steel pipe during conveying, a conveying shaft 103c rotatably mounted on the conveying support plate 103b, two conveying shafts 103c are provided for mounting a conveying belt 103d, the conveying belt 103d mounted on the conveying shaft 103c, a conveying arc plate 103e fixedly mounted on the conveying belt 103d, the conveying arc plate 103e is an arc plate, and one end of the conveying arc plate 103e is in close contact with the surface of the conveying belt 103d, so that the steel pipe can enter the conveying arc plate 103e conveniently, and a conveying motor 103f fixedly mounted on the conveying mounting plate 103a and connected to the conveying shaft 103c, the conveying motor 103f provides power for the rotation of the conveying shaft 103c.

[0036] The buffer portion 104 includes a buffer plate 104a rotatably set on the conveying shaft 103c. The buffer plate 104a is fan-shaped to ensure the normal transportation of the steel pipe, and the buffer plate 104a is made of rubber to increase the buffer effect. A counterweight block 104b is fixedly set on the buffer plate 104a. The setting of the counterweight block 104b allows the buffer plate 104a to be reset by gravity. A groove 104c is set on the buffer plate 104a. The setting of the groove 104c ensures that when the buffer plate 104a is deflected, it will not block the transportation of the steel pipe. Otherwise, when the buffer plate 104a is deflected, the height of one end of the buffer plate 104a exceeds the conveyor belt 103d, which will affect the transportation of the steel pipe.

[0037] The concentric portion 105 includes an extension plate 105a fixedly arranged on the conveying platform 101, a positioning plate 105b fixedly arranged on the extension plate 105a, the top of the positioning plate 105b is semicircular, which is convenient for squeezing the front stopper 203 to deflect, a concentric rotating shaft 105c rotatably arranged on the extension plate 105a, a concentric torsion spring 105d fixedly arranged on the concentric rotating shaft 105c, an offset mounting frame 105e fixedly arranged on the concentric rotating shaft 105c, and a blocking rod 105f fixedly arranged on the extension plate 105a; the arrangement of the concentric rotating shaft 105c and the offset mounting frame 105e makes the rotation center of the temporary storage portion 106 the same as the rotation center of the storage portion 202, so that the temporary storage portion 106 can always be in close contact with the storage portion 202, avoiding point contact between the temporary storage portion 106 and the storage portion 202, thereby balancing the forces between the temporary storage portion 106 and the storage portion 202 and increasing the service life of the device.

[0038] The temporary storage portion 106 includes a temporary mounting plate 106a fixedly mounted on a concentric torsion spring 105d, a temporary rotating shaft 106b rotatably mounted on the temporary mounting plate 106a, two temporary rotating shafts 106b are provided, and a temporary conveyor belt 106c is provided on the temporary rotating shaft 106b. The temporary mounting plate 106a is tilted so as to stably receive the fallen steel pipes and prevent the steel pipes from falling.

[0039] The remaining structures are the same as those of Example 1.

[0040] During use, the cut steel pipe falls onto the blanking plate 102c. Due to the gravity of the steel pipe, the blanking plate 102c is deflected, and the steel pipe rolls along the blanking plate 102c to the conveyor belt 103d. The conveying arc plate 103e limits the steel pipe on the conveyor belt 103d, and the conveying motor 103f is started to drive the conveying shaft 103c to rotate the conveyor belt 103d. The conveyor belt 103d drives the conveying arc plate 103e to move, thereby conveying the steel pipe. When the steel pipe detaches from the conveying arc plate 103e and falls, the buffer plate 104a buffers the steel pipe for the first time, and the buffer plate 104a is deflected. Due to the setting of the counterweight block 104b, gravity causes the buffer plate 104a to automatically reset. After being buffered by the buffer plate 104a, the steel pipe falls into the transfer vehicle 200, thereby completing the transportation of the steel pipe.

[0041] Example 3 Reference Figures 6 to 10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the storage unit 202 includes a storage mounting plate 202a rotatably set on the base 201, a rotating roller 202b rotatably set on the storage mounting plate 202a, the rotating roller 202b is provided with a plurality of rear baffles 202c fixedly set on the base 201, and a buffer spring 202d is set between the rear baffle 202c and the storage mounting plate 202a, one end of the buffer spring 202d is rotatably connected to the rear baffle 202c, and the other end is rotatably connected Connected to the storage mounting plate 202a, the buffer spring 202d is set to buffer the fallen steel pipes and reduce the damage when the steel pipes fall. In addition, as the number of steel pipes increases, the storage mounting plate 202a gradually becomes horizontal, which is convenient for intuitively observing the weight of the steel pipes to prevent overloading. Compared with the existing flatbed trucks that directly stack steel pipes, it is difficult for staff to know the weight of the steel pipes, resulting in frequent overloading. The setting of the buffer spring 202d not only buffers the fallen steel pipes, but also when the storage mounting plate 202a is horizontal, it can be known that the device is fully loaded.

[0042] The front stopper 203 includes a front stopper shaft 203a rotatably arranged on the base 201, and a front stopper frame 203b fixedly arranged on the front stopper shaft 203a. When the front stopper frame 203b is vertical, it can prevent the steel pipe from falling. When the front stopper frame 203b is rotated from tilted to vertical, the steel pipe can be brought into the transfer vehicle 200, and the staff does not need to separately carry the steel pipe dropped during transportation, which saves a certain amount of labor. The front stopper torsion spring 203c fixedly arranged on the front stopper shaft 203a is used for buffering when the front stopper frame 203b rotates. The front stopper compensation block 203d arranged on the fixed front stopper frame 203b is used for thickness compensation, so that the positioning plate 105b can squeeze the front stopper frame 203b to be vertical. The front stopper limit block 203e fixedly arranged on the base 201 is used to limit the front stopper frame 203b to prevent the front stopper frame 203b from excessive rotation, thereby ensuring the normal use of the device.

[0043] The latch portion 204 includes a latch mounting groove 204a arranged on the front gear shaft 203a, a latch spring 204b fixedly arranged in the latch mounting groove 204a, and a latch rod 204c fixedly arranged on the latch spring 204b. One end of the latch rod 204c is hemispherically arranged to facilitate the latch rod 204c to disengage from the second gear groove 205g. When the latch rod 204c is inserted into the second gear groove 205g, the stability of the front gear frame 203b when it is vertical can be ensured, thereby ensuring the normal use of the device.

[0044] The pedaling part 205 includes a first rotating shaft 205a rotatably set on the base 201, a first gear 205b fixedly set on the first rotating shaft 205a, a second rotating shaft 205c rotatably set on the base 201, a second gear 205d fixedly set on the second rotating shaft 205c, a cam 205e fixedly set on the second rotating shaft 205c and adapted to the latch rod 204c, a first gear groove 205f set in the base 201 and adapted to the first gear 205b, a second gear groove 205g set in the base 201 and adapted to the cam 205e, and a pedal 205h fixedly set on the first rotating shaft 205a.

[0045] The remaining structure is the same as that of Example 2.

[0046] During use, the steel pipes dropped into the transfer vehicle 200 hit the temporary conveyor belt 106c, and the deflection of the temporary conveyor belt 106c drives the storage mounting plate 202a to deflect, and the elastic force of the buffer spring 202d buffers the impact of the steel pipes. When there are many steel pipes, the gravity of the steel pipes makes the temporary conveyor belt 106c and the rotating roller 202b in a horizontal state. At this time, the transfer vehicle 200 is fully loaded, and the steel pipes on the transfer vehicle 200 need to be transferred. The base 201 is pulled to move the base 201, and the base 201 The front baffle 203b is driven to move, and the front baffle 203b makes the steel pipe move with the base 201. When the steel pipe moves to the right with the base 201, due to the friction force, the steel pipe drives the top of the temporary conveyor belt 106c to move to the right, and the bottom of the temporary conveyor belt 106c moves to the left, so that when the temporary conveyor belt 106c is pulled out, there is rolling friction between the temporary conveyor belt 106c, the steel pipe and the rotating roller 202b, which facilitates the extraction of the temporary conveyor belt 106c, and the fully loaded transfer vehicle 200 can be transferred to the storage place; When the fully loaded transfer vehicle 200 is transported out and the empty transfer vehicle 200 has not yet been transported in, the steel pipes continuously transported by the conveying unit 103 fall onto the temporary conveyor belt 106c for temporary storage; The unloaded transfer vehicle 200 is docked with the conveying mechanism 100 to carry out the transfer operation, and the unloaded base 201 is pushed to the conveying platform 101. The pedal 205h is stepped on to drive the first rotating shaft 205a to rotate the first gear 205b, and the first gear 205b drives the second gear 205d to rotate the second rotating shaft 205c, and the second rotating shaft 205c drives the cam 205e to rotate in the opposite direction, and the cam 205e squeezes the latch rod 204c to disengage from the second gear groove 205g, thereby releasing the limit on the front block rotating shaft 203a, and the front block frame 203b is deflected due to gravity, and the front block torsion spring 203c buffers the deflection, pushing the base 201 to make the front block frame 203b squeeze the positioning plate 105b, and the front block frame 203b is reset to a vertical state. At the same time, some of the steel pipes temporarily stored in the temporary conveyor belt 106c are brought into the transfer vehicle 200, thereby completing the docking.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
