Description

Technical Field

[0001] The present application relates to the technical field of shield machine construction, and in particular to a conveying and collecting device for a split starting pipeline of a deep well shield machine. Background Art

[0002] The start of shield machine is a construction process in which the shield machine enters the normal excavation working state from the assembly state. Normally, it is started as a whole in the working shaft. However, in some cases, due to the limitation of site space and the overall length of the shield machine and its subsequent supporting trolley, it cannot be started after the whole machine is assembled in the starting shaft at one time. It is necessary to adopt a split starting mode in which the main machine and other parts of the shield machine are assembled in the shaft, and the rest are temporarily assembled on the ground and work together together, and an extension pipeline is used to connect the underground shield main machine part with the subsequent trolley on the shaft.

[0003] However, during this period, pipelines were laid at the wellhead and on the ground. Since there were many and messy pipelines on the ground, there was a great safety risk. Utility Model Content

[0008] A conveying guide rod rotatably connected between the first limiting plate and the second limiting plate, and correspondingly, four conveying guide rods are provided;

[0009] Among them, the heights of the four first limit plates decrease successively, the heights of the four second limit plates decrease successively, and correspondingly, the installation heights of the four conveying guide rods also decrease successively, thereby forming a downwardly inclined conveying guide groove.

[0031] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0032] Embodiment 1:

[0033] See also Figure 1 A conveying and collecting device for a deep well shield split starting pipeline, the conveying and collecting device for a deep well shield split starting pipeline comprises:

[0034] A first bracket 1 and a second bracket 2 are arranged in parallel, four first limit plates 3 are arranged at the upper end of the first bracket 1, and four second limit plates 4 are arranged at the upper end of the second bracket 2, and the four first limit plates 3 correspond to the four second limit plates 4 one by one;

[0035] A conveying guide rod 5 rotatably connected between the first limiting plate 3 and the second limiting plate 4, and correspondingly, four conveying guide rods 5 are provided;

[0036] The heights of the four first limit plates 3 decrease in sequence, the heights of the four second limit plates 4 decrease in sequence, and correspondingly, the installation heights of the four conveying guide rods 5 also decrease in sequence, thereby forming a downwardly inclined conveying guide groove.

[0037] Specifically, the spacing between the first bracket 1 and the second bracket 2 is 800 mm to adapt to the density of the deep well shield split starting pipeline. The upper end surface of the first bracket 1 is fixedly connected to the lower end surface of the first limit plate 3, and the first limit plate 3 is provided with a mounting hole for allowing the conveying guide rod 5 to pass through. The upper end surface of the second bracket 2 is fixedly connected to the lower end surface of the second limit plate 4, and the second limit plate 4 is provided with a mounting hole for allowing the conveying guide rod 5 to pass through.

[0038] The mounting holes on the first limiting plate 3 correspond to the mounting holes on the second limiting plate 4 one by one, and the conveying guide rod 5 is passed through the two mounting holes and is rotatably connected to the first limiting plate 3 and the second limiting plate 4;

[0039] Since the heights of the four first limit plates 3 decrease successively, the heights of the four second limit plates 4 decrease successively, and thus the mounting holes on the four first limit plates 3 also decrease successively, and the mounting holes on the four second limit plates 4 also decrease successively, so that the installation heights of the four conveying guide rods 5 decrease successively, thereby forming a downward inclined conveying guide groove.

[0040] When in use, the device is placed at the mouth of the shield well, and the shield machine pipeline is placed on the four conveying guide rods 5. As the shield machine body advances, the pipeline gradually extends in the conveying guide groove formed by the four conveying guide rods 5, thereby realizing the transportation of the pipeline. At the same time, due to the restrictions of the first limit plate 3 and the second limit plate 4, the pipeline can only move in the conveying guide groove and cannot be scattered on the ground, so it becomes regular and orderly, thereby avoiding the safety risks caused by the layout of many and messy pipelines on the ground.

[0041] In addition, in the traditional process of pipeline going down the well, the ground pipeline directly contacts the well edge, and the contact part forms 90 degrees. The pipeline is vertically suspended at the well edge. The vertically suspended pipeline will bend after contacting the well edge, resulting in blockage of the oil and water supply pipelines leading to the shield machine body, thereby causing the shield machine to be unable to advance and operate. The pipeline is placed on the four conveying guide rods 5 of the device. Since the conveying guide rods 5 are round guide rods with a certain curvature, the pipeline will not bend when in contact with the conveying guide rods 5, and the pipeline will not contact the well edge during transportation, so it will not bend, thereby preventing the problem of the shield machine being unable to advance and operate due to blockage of the oil and water supply pipelines.

[0042] Embodiment 2:

[0043] See also Figure 2 , based on the first embodiment, further and optionally, the front lower end of the first bracket 1 is provided with two first supports 6, and the front lower end of the second bracket 2 is provided with two second supports 7;

[0044] The two first supports 6 and the two second supports 7 correspond to each other one by one.

[0045] Specifically, the upper end of the first support 6 is fixedly connected to the front lower end of the first bracket 1, and the upper end of the second support 7 is fixedly connected to the front lower end of the second bracket 2;

[0046] When in use, the device is placed at the wellhead, the first support 6 and the second support 7 are fixed at the wellhead and stuck in front of the outer wall of the well to prevent the device from moving during pipeline transportation, thereby enhancing the stability of pipeline transportation.

[0047] Further and optionally, three connecting rods 8 are provided between the first bracket 1 and the second bracket 2 .

[0048] Specifically, one end of the connecting rod 8 is fixedly connected to the side of the first bracket 1, and the other end is fixedly connected to the side of the second bracket 2. This arrangement, on the one hand, enhances the structural strength of the device, and on the other hand, the connecting rod 8 away from the first support 6 and the second support can assist in supporting the pipeline.

[0049] Further and optionally, the first bracket 1, the second bracket 2, the first limiting plate 3, the second limiting plate 4, the first support 6 and the second support 7 are all made of No. 10 channel steel.

[0050] Specifically, No. 10 channel steel has the advantages of being light, high in strength, low in price, and easy to process. Moreover, since the channel steel is light, it is more convenient to move the device.

[0051] Further and optionally, the lengths of the first bracket 1 and the second bracket 2 are both 1200 mm.

[0052] Specifically, since the lengths of the first bracket 1 and the second bracket 2 are selected according to actual conditions, in this embodiment, the lengths of the first bracket 1 and the second bracket 2 are set to 1200 mm, which can not only meet the transportation requirements of the pipeline, but also ensure that the device has a certain degree of portability.

[0053] Further and optionally, the height of the first support 6 and the second support 7 are both 200 mm.

[0054] Specifically, the height of the first support 6 and the second support 7 is selected according to the actual situation of the shield wellhead. In this embodiment, the height of the first support 6 and the second support 7 is set to 200 mm to meet the requirements, while also ensuring that the device has a certain degree of portability.

[0055] Further and optionally, the conveying guide rod 5 is a steel pipe with an outer diameter of 20 mm, a wall thickness of 3 mm, and a length of 1000 mm.

[0056] Specifically, the length of the conveying guide rod 5 is 1000 mm, which is greater than the distance between the first bracket 1 and the second bracket 2, to ensure that the conveying guide rod 5 can be installed on the first limit plate 3 and the second limit plate 4, and the conveying guide rod 5 adopts a hollow steel pipe with an outer diameter of 20 mm and a wall thickness of 3 mm, which can ensure strength while avoiding excessive weight of the device.

[0057] Further and optionally, the connecting rod 8 is a steel pipe with an outer diameter of 32 mm, a wall thickness of 3 mm, and a length of 800 mm.

[0058] Specifically, the length of the connecting rod 8 is 800 mm to match the distance between the first bracket 1 and the second bracket 2, so as to ensure that the connecting rod 8 is just fixed between the first bracket 1 and the second bracket 2, and the connecting rod 8 adopts a hollow steel pipe with an outer diameter of 32 mm and a wall thickness of 3 mm, which can ensure strength while avoiding excessive weight of the device.

[0059] In summary, the present application places the pipeline of the shield machine on the four conveying guide rods 5. As the shield machine body is excavated, the pipeline gradually extends in the conveying guide groove formed by the four conveying guide rods 5, thereby realizing the conveying of the pipeline. At the same time, due to the restrictions of the first limiting plate 3 and the second limiting plate 4, the pipeline can only move in the conveying guide groove and cannot be scattered on the ground, so it becomes regular and orderly, thereby avoiding the safety risk caused by the multiple and messy pipelines laid on the ground.

[0060] In addition, in the process of traditional pipelines going down the well, the ground pipeline directly contacts the well edge, and the contact part forms a 90-degree angle. The pipeline is suspended vertically at the well edge. The vertically suspended pipeline will bend after contacting the well edge, resulting in blockage of the oil and water supply pipelines leading to the shield machine body, thereby causing the shield machine to be unable to advance. The pipeline is placed on the four conveying guide rods 5 of the device. Since the conveying guide rods 5 are round guide rods with a certain curvature, the pipeline will not bend when contacting the conveying guide rods 5, and the pipeline will not contact the well edge during transportation, so it will not bend, thereby preventing the problem of the shield machine being unable to advance due to blockage of the oil and water supply pipelines.

[0061] The present application fixes the first support 6 and the second support 7 at the wellhead and clamps them in front of the outer wall of the shield well to prevent the device from moving during the pipeline transportation process, thereby enhancing the stability of pipeline transportation;

[0062] The first bracket 1, the second bracket 2, the first limit plate 3, the second limit plate 4, the first support 6 and the second support 7 of the present application are all made of No. 10 channel steel. No. 10 channel steel has the advantages of being light, strong, low-priced and easy to process. In addition, since the channel steel is light, it is more convenient to move the device.

[0063] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
