Description

Technical Field

[0001] The utility model belongs to the technical field of completion tool production, and particularly relates to a multi-stage buffer material receiving mechanism for producing sliding sleeve body pipes. Background Art

[0002] At present, in order to realize the production and testing of different oil layers, a production sliding sleeve is required to provide a liquid flow channel between the tubing and the annulus. The production sliding sleeve is opened by the method of repeatedly gravity hammering the shifting tool. The shifting tool is flipped 180°, and an upward traction force is applied to the shifting station through a winch to realize the upward shifting and closing of the production sliding sleeve. When the production sliding sleeve body pipe is received after being cut by the manipulator gripper, when the receiving position of the production sliding sleeve body pipe is relatively low, it is more convenient for the operator to manually carry the production sliding sleeve body pipe. When the production sliding sleeve body pipe is transferred to a lower position for receiving by the manipulator gripper, the requirement for the stroke distance of the manipulator gripper is relatively high, which not only increases the use cost of the manipulator gripper, but also increases the requirement for the height of the production workshop. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a multi-stage buffer material receiving mechanism for producing sliding sleeve body pipes with low requirement for the height stroke distance of the manipulator gripper and convenient for the operator to manually receive materials.

[0004] To solve the above technical problem, the present invention is realized through the following technical solutions: A multi-stage buffer material receiving mechanism for producing sliding sleeve body pipes, comprising a workbench main body, a first-stage material receiving inclined plate, a second-stage material receiving inclined plate, two buffer sleeves and a buffer. The first-stage material receiving inclined plate and the second-stage material receiving inclined plate are both fixedly installed on the workbench main body in an inclined manner. The second-stage material receiving inclined plate is located below the first-stage material receiving inclined plate. One buffer sleeve is fixedly installed at the top of the first-stage material receiving inclined plate, and the other buffer sleeve is fixedly installed at the bottom of the first-stage material receiving inclined plate. The buffer sleeve has a buffer channel that penetrates up and down. The buffers are linearly distributed on both the left and right sides of the buffer sleeve.

[0005] The buffer is composed of a round head pin, a baffle, a spring and a limit bolt. The round head pin is slidably installed on both sides of the left side of the buffer sleeve. The round head end of the round head pin is located in the buffer channel. The baffle is fixedly installed at the outer end of the round head pin. The tension spring is sleeved on the round head pin. The two ends of the tension spring are respectively fixedly connected to the baffle and the outer wall of the buffer sleeve. The limit bolt is screwed and fixedly installed on the baffle. The inner end of the limit bolt can abut against the outer wall of the buffer sleeve.

[0006] Furthermore, both sides of the top opening of the buffer channel are provided with bevel structures.

[0007] Further, the front and rear ends of the buffer sleeve extend 2-3 cm beyond the front and rear ends of the first-stage material receiving inclined plate, and the length dimensions of the front and rear ends of the buffer channel are the same as those of the inner walls of the front and rear sides of the first-stage material receiving inclined plate and are arranged corresponding to them.

[0008] Further, the buffer sleeve located at the bottom of the first-stage material receiving inclined plate is also fixedly connected to the workbench main body through a reinforcing support rod.

[0009] Further, a rubber buffer pad is fixedly arranged inside the second-stage material receiving inclined plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the buffer, this mechanism can buffer the production sliding sleeve body pipes in the buffer sleeve multiple times, thereby reducing the impact force when the production sliding sleeve body pipes fall on the first-stage material receiving inclined plate and the second-stage material receiving inclined plate, avoiding impact scratches on the surface of the production sliding sleeve body pipes, reducing the noise in the production workshop at the same time. In addition, without increasing the longitudinal stroke distance of the manipulator gripper, through multiple buffer drops, the production sliding sleeve body pipes can fall on the second-stage material receiving inclined plate with a lower position, facilitating the operator to manually carry and collect the production sliding sleeve body pipes in the second-stage material receiving inclined plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present utility model will be further described below with reference to the drawings.

[0012] Figure 1 is a schematic diagram of the internal structure of the present utility model.

[0013] Figure 2 is Figure 1 the enlarged structural schematic diagram at M of DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be described in detail below in conjunction with the specific embodiments:

[0015] As Figure 1 and Figure 2 shown, a multi-stage buffer material receiving mechanism for producing sliding sleeve body pipes includes a workbench main body 1, a first-stage material receiving inclined plate 2, a second-stage material receiving inclined plate 3, two buffer sleeves 4 and a buffer 5. The first-stage material receiving inclined plate 2 and the second-stage material receiving inclined plate 3 are both inclined and fixedly installed on the workbench main body 1. The second-stage material receiving inclined plate 3 is located below the first-stage material receiving inclined plate 2. One buffer sleeve 4 is fixedly installed at the top of the first-stage material receiving inclined plate 2, and the other buffer sleeve 4 is fixedly installed at the bottom of the first-stage material receiving inclined plate 2. The buffer sleeve 4 has a buffer channel 40 that penetrates up and down. The buffers 5 are linearly distributed on the left and right sides of the buffer sleeve 4;

[0016] The buffer 5 is composed of a round head pin 51, a baffle 52, a spring 53 and a limit bolt 54. The round head pin 51 is slidably installed on both sides of the left side of the buffer sleeve 4. The round head end of the round head pin 51 is located in the buffer channel 40. The baffle 52 is fixedly installed at the outer end of the round head pin 51. The tension spring 53 is sleeved on the round head pin 51. Both ends of the tension spring 53 are fixedly connected to the baffle 52 and the outer wall of the buffer sleeve 4 respectively. The limit bolt 54 is screwed and fixedly installed on the baffle 52. The inner end of the limit bolt 54 can abut against the outer wall of the buffer sleeve 4.

[0017] Both sides of the top opening of the buffer channel 40 are arranged in an inclined angle structure to facilitate the easy sliding of the production sliding sleeve body pipe into the buffer channel 40.

[0018] Both the front and rear ends of the buffer sleeve 4 extend 2 - 3 cm beyond the front and rear ends of the first - stage material receiving inclined plate 2 to facilitate the installation and fixation of the buffer sleeve 4 and the first - stage material receiving inclined plate 2. The length dimensions of the front and rear ends of the buffer channel 40 are the same as and are set corresponding to the length dimensions of the front and rear inner walls of the first - stage material receiving inclined plate 2 to meet the actual use requirements and avoid problems such as jamming and hindrance to the production of the sliding sleeve body pipe due to non - corresponding dimensions.

[0019] Since the buffer sleeve 4 at the bottom of the first - stage material receiving inclined plate 2 has a relatively long height dimension, the buffer sleeve 4 at the bottom of the first - stage material receiving inclined plate 2 is also fixedly connected to the workbench main body 1 through a reinforcing support rod to improve the installation structural strength of the buffer sleeve 4 at the bottom of the first - stage material receiving inclined plate 2.

[0020] A rubber buffer pad 31 is fixedly arranged inside the second - stage material receiving inclined plate 3. When the produced sliding sleeve body pipe falls on the second - stage material receiving inclined plate 3, the rubber buffer pad 31 can play a buffering role.

[0021] The produced sliding sleeve body pipe 10 clamped by the manipulator jaw is placed in the buffer channel 40 of the buffer sleeve 4 at the top of the first - stage material receiving inclined plate 2. The produced sliding sleeve body pipe 10 moves downward under the action of its own gravity and comes into contact with the two round head pins 51. At this time, a first - stage buffering occurs. The produced sliding sleeve body pipe 10 squeezes the two round head pins 51 under the action of its own gravity and moves outward against the tension of the tension spring 53 until the produced sliding sleeve body pipe 10 passes through the two round head pins 51 of this layer and falls onto the two round head pins 51 of the lower layer for another buffering until the produced sliding sleeve body pipe 10 falls onto the first - stage material receiving inclined plate 2. The produced sliding sleeve body pipe 10 slides downward on the first - stage material receiving inclined plate 2 and falls into the buffer sleeve 4 below it, and after being buffered by the buffer 5 multiple times, it falls onto the second - stage material receiving inclined plate 3, thereby facilitating the operator to manually carry and collect the produced sliding sleeve body pipe 10 in the second - stage material receiving inclined plate 3.
