Description

Technical Field

[0001] The utility model relates to the field of pipe processing equipment, in particular to a pipe hoist. Background Art

[0002] In the field of pipe processing, pipes are often required to be processed in various forms, some pipes need to be cut, some pipes need to be bent, and some pipes need to be welded; however, no matter what form the pipes are processed in, automatic loading of pipes must be achieved on the automated production line, which is the basic condition for achieving automated production. In the existing pipe production process, it is common that the cutting and unloading of pipes and the subsequent processing procedures cannot be directly connected. Therefore, most pipe processing procedures start with the elevator, and the pipes are manually replenished into the elevator's silo interval.

[0003] The invention patent with Chinese patent application number CN202022636978.0 discloses an automatic feeding device for pipe fittings, including a storage box, a feeding mechanism and a transmission mechanism. The feeding mechanism is located between the storage box and the transmission mechanism, and is used to regularly convey pipe fittings to the transmission mechanism. The storage box is open on one side facing the feeding mechanism, and the bottom is a slope inclined in the direction of the feeding mechanism; the transmission mechanism includes a fixed base, a pulley, a conveyor belt, a baffle and a transition plate, the pulley is located between two baffles and is rotatably connected to the baffles, and a rotating wheel with a diameter greater than the diameter of the rotating shaft is symmetrically distributed in the middle of the pulley. The conveyor belt is sleeved on the rotating wheels of the two pulleys, and a notch is provided at the part of the baffle opposite to the feeding mechanism, and an L-shaped transition plate is horizontally connected to the notch, and the transition plate abuts against the feeding mechanism; the fixed base includes a base and a support rod, and the support rod is plugged into the base and fixed by an adjusting bolt; the utility model can be applied to the automatic feeding of pipe fittings of different diameters and keep the axis always in a straight line.

[0004] However, the equipment only uses one material storage box. When the elevator is manually refilled with materials, the elevator needs to be paused, which affects production efficiency. Utility Model Content

[0005] In view of the above problems, the utility model provides a pipe lifting machine, which provides two groups of storage bin assemblies and drives two groups of discharge bin assemblies to alternately connect with the lifting mechanism through a power assembly. The lifting mechanism pushes out the pipes in the storage bin assemblies one by one, thereby solving the technical problem in the prior art that it is impossible to replenish materials without stopping the machine, resulting in low production efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pipe lifting machine includes a material storage mechanism and a lifting mechanism. The material storage mechanism includes a pair of ground rails arranged horizontally on one side of the lifting mechanism, two groups of storage bin assemblies slidably arranged side by side on the ground rails and capable of alternately docking with the lifting mechanism, and a power assembly driving the two groups of storage bin assemblies to move. When docking, the lifting mechanism pushes out the pipes in the storage bin assemblies one by one.

[0008] As an improvement, the storage bin assembly includes a bracket, a bin fixedly mounted on the bracket, a guide wheel arranged at the bottom of the bracket and rollingly engaged on the ground rail, and a partition unit arranged in the bin.

[0009] As an improvement, a plurality of groups of material top-loading areas are spaced apart on one side where the silo interfaces with the lifting mechanism, and a material guide plate a tilted downward is provided on the outer sides of the tops of the plurality of material top-loading areas, and the bottom of the silo is tilted upward in a direction away from the material top-loading area.

[0010] As an improvement, the partition unit includes two groups of supporting optical axes arranged side by side in the internal space of the silo, sliding seats correspondingly slidably sleeved on the supporting optical axes, and partitions fixedly mounted on the two groups of sliding seats.

[0011] As an improvement, the power assembly includes limit seats arranged at both ends of the ground rail, hydraulic buffers arranged correspondingly on the limit seats, limit screws arranged at the same height on one side of the hydraulic buffer, a mounting plate installed on the two groups of storage bin assemblies, and a cylinder a installed on the mounting plate and with the power output end fixedly connected to any group of the limit seats.

[0012] As an improvement, the lifting mechanism includes a mounting frame, a front baffle unit arranged above the front side of the mounting frame, a material guide plate b arranged at the top of the front baffle unit and capable of transitionally docking with the material guide plate a, and a material lifting assembly installed on the mounting frame and located on the rear side of the front baffle unit. The material lifting assembly moves upward in the material lifting area to deliver the pipe fittings at the bottom of the silo to the material guide plate a.

[0013] As an improvement, the lifting assembly includes a connecting seat installed on the mounting frame, a cylinder b arranged on the connecting seat, linear bearings symmetrically arranged on both sides of the cylinder b, a guide light shaft sliding through the linear bearings, a lifting plate installed on the top ends of the two groups of guide light shafts and connected to the power output end of the cylinder b, and lifting blocks installed at intervals on the lifting plate and capable of extending into the lifting area accordingly.

[0014] As an improvement, the top end of the top material block is inclined.

[0015] The beneficial effects of the utility model are:

[0016] (1) In the utility model, the power assembly drives two groups of storage bin assemblies to alternately connect with the lifting mechanism. When one storage bin assembly connects with the lifting mechanism, the lifting mechanism works, and the other group of storage bin assemblies is manually replenished, thereby realizing a two-to-one feeding mode, which greatly improves the lifting efficiency of the elevator;

[0017] (2) The hydraulic buffer and the limit screw installed on the limit seat in the utility model cooperate with the cylinder a to achieve the movement accuracy of the storage bin assembly, thereby improving the docking accuracy of the storage bin assembly and the lifting mechanism;

[0018] (3) In the utility model, the partitions provided in the silo can be adjusted by the length of the pipe. The distance between the partitions and the side walls of the silo is slightly greater than the length of the pipe. When the silo is manually refilled, the pipe is laid on the bottom of the silo. During the operation of the lifting mechanism, the pipe will automatically roll downward. The partitions prevent the pipe from rolling off the side, thereby ensuring the stability of the loading.

[0019] In summary, the utility model has the advantages of simple structure, convenient maintenance and high material pushing efficiency, and is particularly suitable for the field of pipe processing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example:

[0028] like Figure 1 As shown, a pipe lifting machine includes a storage mechanism 1 and a lifting mechanism 2, wherein the storage mechanism 1 includes a pair of ground rails 10 arranged horizontally on one side of the lifting mechanism 2, two groups of storage bin assemblies 11 slidably arranged side by side on the ground rails 10 and alternately docked with the lifting mechanism 2, and a power assembly 12 for driving the two groups of storage bin assemblies 11 to move. When docking, the lifting mechanism 2 pushes out the pipes in the storage bin assemblies 11 one by one.

[0029] Furthermore, the storage bin assembly 11 includes a bracket 111, a bin 112 fixedly mounted on the bracket 111, a guide wheel 113 disposed at the bottom of the bracket 111 and rollingly engaged on the ground rail 10, and a partition unit 114 disposed in the bin 112.

[0030] It should be noted that the two groups of brackets 111 are fixedly connected via a connecting rod.

[0031] Further, such as Figure 1 and Figure 2 As shown, a plurality of groups of material top-loading areas 1121 are spaced apart from each other on one side where the silo 112 is docked with the lifting mechanism 2, and a material guide plate a1122 inclined downward is provided on the outer sides of the tops of the plurality of groups of material top-loading areas 1121, and the bottom of the silo 112 is inclined upward in a direction away from the material top-loading area 1121.

[0032] It should be noted that the bottom of the silo 112 and the guide plate a1122 are arranged at an angle to facilitate the rolling of the pipe.

[0033] Furthermore, the partition unit 114 includes two groups of supporting optical axes 1141 arranged side by side in the internal space of the silo 112 , sliding seats 1142 correspondingly slidably sleeved on the supporting optical axes 1141 , and partitions 1143 fixedly mounted on the two groups of sliding seats 1142 .

[0034] It should be noted that the sliding seat 1142 is a LHRC16 linear bearing with a clamping handle, and the sliding seat 1142 can be moved to a suitable position for fixation.

[0035] It is also necessary to explain that the position of the partition 1143 is adjusted so that the distance between it and the side wall of the silo 112 is slightly larger than the length of the pipe, so that the pipe will not roll off the side during the rolling process, thereby improving the stability of the top material.

[0036] Further, such as Figure 1 As shown, the power assembly 12 includes limit seats 121 arranged at both ends of the ground rail 10, oil pressure buffers 122 correspondingly arranged on the limit seats 121, limit screws 123 arranged at the same height on one side of the oil pressure buffer 122, a mounting plate 124 installed on the two groups of storage bin assemblies 11, and a cylinder a125 installed on the mounting plate 124 and with the power output end fixedly connected to any group of the limit seats 121.

[0037] It should be noted that the cylinder a125 drives the two groups of the storage bin assemblies 11 to move, and the bracket 111 contacts the oil pressure buffer 122 first, and finally conflicts with the limit screw 123, thereby achieving positioning.

[0038] It should be further explained that, in order to further improve the positioning accuracy of the bracket 111, when the limit screw 123 conflicts with the bracket 111, the stroke of the cylinder a125 is not completed.

[0039] It should be further explained that the mounting plate 124 is mounted on two groups of the brackets 111 .

[0040] It should be further explained that the cylinder a123 is DN50×650, and the oil pressure buffer 122 is SAC-2050C.

[0041] Further, such as Figure 3As shown, the lifting mechanism 2 includes a mounting frame 21, a front baffle unit 22 arranged above the front side of the mounting frame 21, a material guide plate b23 arranged at the top of the front baffle unit 22 and capable of transitionally docking with the material guide plate a1122, and a material lifting assembly 24 installed on the mounting frame 21 and located at the rear side of the front baffle unit 22. The material lifting assembly 24 moves upward in the material lifting area 1121 to deliver the pipe fittings at the bottom of the silo 112 to the material guide plate a1122.

[0042] Further, such as Figure 3 and Figure 4 As shown, the lifting assembly 24 includes a connecting seat 241 installed on the mounting frame 21, a cylinder b242 arranged on the connecting seat 241, linear bearings 243 symmetrically arranged on both sides of the cylinder b242, a guide light shaft 244 slidingly inserted in the linear bearing 243, a lifting plate 245 installed on the top of the two groups of guide light shafts 244 and connected to the power output end of the cylinder b242, and a lifting block 246 installed at intervals on the lifting plate 245 and capable of correspondingly extending into the lifting area 1121.

[0043] Furthermore, the top of the lifting block 246 is inclined.

[0044] It should be noted that the cylinder b242 drives the lifting plate 245 to move upward, and then the lifting block 246 drives the pipes in the lifting area 1121 to be sent to the guide plate a1122, and finally roll out from the guide plate b23.

[0045] It is also necessary to explain that the top of the lifting block 246 is inclined to ensure that the pipe fittings will not fall during the lifting process.

[0046] It should be further explained that the cylinder b242 is DN40×300, and the linear bearing 243 is LMF20LUU.

[0047] It is important to note that only when the cylinder b242 is located at the original position at the bottom, can the power assembly 12 drive the storage bin assembly 11 to move.

[0048] Working process:

[0049] like Figure 4As shown, pipes are manually laid at the bottom of the silo 112, and then the cylinder a125 drives the two groups of the storage silo assemblies 11 to move, and the bracket 111 contacts the hydraulic buffer 122 first, and finally conflicts with the limit screw 123. At this time, the silo 112 with pipes inside is docked with the front baffle unit 22, and the cylinder b242 drives the lifting plate 245 to move upward, and then the lifting block 246 drives the pipes in the lifting area 1121 to be sent to the guide plate a1122, and finally roll out from the guide plate b23.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
