Description

Technical Field

[0001] The utility model relates to the technical field of shield construction, in particular to a flushing nozzle device with adjustable angle. Background Art

It is an indispensable part of the slurry shield circulation system. Its flushing efficiency is directly related to the slag discharge performance of the shield machine and affects the working capacity of the shield machine.

[0003] At present, the flushing nozzle widely used in the industry is a general pipeline nozzle, which has a simple structure and a single flushing angle. The accumulation of slag in the bin is a dynamic process. If the flushing angle and flushing position are not designed reasonably, it will not only fail to disperse the accumulated slag and promote slag discharge, but also lead to the deterioration of the flow field in the bin, more serious accumulation of slag, and the consequence of blockage and stagnation.

[0004] At present, there are flushing nozzle structures with adjustable angles on the market, such as a new type of flushing nozzle device with adjustable angles disclosed in Chinese patent publication number CN208380571U. Although the device can play a certain angle adjustment function, it can only be adjusted in one dimension, and it is not very effective for complex working conditions. Therefore, it is necessary to design a flushing nozzle device with a relatively simple and reasonable structure and capable of multi-dimensional angle adjustment. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 , 2 As shown, in embodiment 1, an adjustable angle flushing nozzle device comprises a flange seat 8, and the adjustable angle nozzle device is connected to the flushing pipe through the flange seat 8; a spherical nozzle 7 is arranged in the flange seat 8, and the spherical nozzle 7 is limited in the flange seat 8 in the form of a ball hinge through the end cover 6, that is, a spherical groove is arranged in the flange seat 8, and the spherical nozzle is located in the spherical groove to form a ball hinge. The nozzle part of the spherical nozzle 7 extends out of the end cover 6 to avoid interference with the end cover during the angle adjustment process. At least one regulator 1 for adjusting the angle of the spherical nozzle 7 is arranged on the flange seat 8; the regulator 1 is in contact with the spherical nozzle 7, and under the action of the regulator 1, the spherical nozzle 7 can freely adjust the flushing angle of the nozzle within a certain range to improve the flushing efficiency. A distance measuring device 4 is arranged on the end cover 6; the distance measuring device 4 can use a laser rangefinder to capture the information such as the accumulation position and height of the slag in the current bin, and then transmit the information to the controller, and the controller controls the action of the regulator, thereby achieving the purpose of accurately adjusting the spherical nozzle 7. As a preference, two distance measuring devices 4 can be provided (distance measuring device 4 and distance measuring device 5), and the two distance measuring devices are also arranged at 90 degrees to improve the accuracy of distance measurement. Figure 6 As shown, a posture sensor 71 is embedded on the spherical surface of the spherical nozzle 7. Accurate and directional adjustment is achieved through feedback data from the posture sensor.

[0030] As a further preferred embodiment, Figure 3As shown, the flange seat 8 includes a flange portion 8-1, a connecting tube portion 8-2 and a ball seat portion 8-3. The flange portion 8-1 is used to connect to the flushing pipe, and the connecting tube portion 8-2 connects the ball seat portion 8-3 and the flange portion 8-1. The end cover 6 is connected to the front end surface of the ball seat portion 8-3 through a connecting bolt 2; the ball seat portion 8-3 is provided with a buckle 8-4 for fixing the end cover 6, which is convenient for positioning and fixing the end cover, and the regulator 1 is arranged on the ball seat portion 8-3; so that the spherical nozzle 7 can be stably and accurately adjusted.

[0031] As a further preferred embodiment, the regulator 1 includes a box seat 101, and the side of the box seat facing the flange seat 8 is an arc-shaped surface so as to be more closely fitted with the flange seat. A retractable push rod 102 is provided in the box seat 101, and the push rod 102 can be retracted relative to the box seat, and the extension length of the push rod can be adjusted to adjust the spherical nozzle 7 in the direction of the ball diameter. A friction roller 103 is provided at one end of the push rod 102 extending from the box seat 101, and the friction roller 103 is in contact with the spherical nozzle 7. In this embodiment, the push rod 102 can adopt a telescopic rod with a telescopic function; the roller surface of the friction roller 103 and the surface of the spherical nozzle are both provided with anti-slip and wear-resistant structures, and the accurate adjustment of the flushing direction of the spherical nozzle is achieved through the friction between the actively rotating friction roller and the surface of the spherical nozzle.

[0032] like Figure 4 As shown, Example 2 is an adjustable angle flushing nozzle device. Based on Example 1, this example is further optimized: two push rods 102 are symmetrically arranged in the box seat 101, and the two ends of the axle of the friction roller 103 are rotatably connected to the two push rods 102. The two push rods support the friction roller 103 at both ends to ensure the stability of the friction roller. The friction roller 103 is connected to the rotation drive mechanism set on the push rod 102; the rotation drive mechanism is used to drive the friction roller to rotate. In the process of adjusting the angle of the spherical nozzle 7, the friction roller uses friction to drive the spherical nozzle to roll, so as to adjust the spherical nozzle 7 in multiple dimensions.

[0033] As an implementation mode, the rotation drive mechanism described in this embodiment includes a drive motor 104 disposed on the push rod 102, and the drive motor 104 drives the friction roller 103 to actively rotate. The drive motor can also be directly connected to the axle of the friction roller using a reducer, or a gear pair can be used to drive the friction roller to actively rotate. The friction roller can be rotated at a suitable speed. In this embodiment, the drive motor is directly connected to the axle of the friction roller as an example, and the drive motor can be connected to the push rod through a cover. Alternatively, the thickness of the push rod is increased, and the drive motor is embedded in the push rod, so as not to interfere.

Under the action of the first motor, the screw rod rotates, driving the threaded seat and the push rod to move along the slideway, realizing the extension and retraction of the push rod, which is used to adjust the spherical nozzle in the ball diameter direction.

[0035] In the present embodiment, two regulators 1 are arranged on the flange seat 8. The two regulators (regulator 1 and regulator 3) are arranged circumferentially along the flange seat 8 at 90°. The push rod 102 extends into the flange seat 8 to make the friction roller 103 contact the spherical nozzle 7. The spherical nozzle structure is adopted, and two rolling devices are arranged at 90° to each other, which can realize universal adjustment within 30° in the direction of nozzle flushing according to actual needs. When one of the regulators is working, the other regulator shrinks and the roller is separated from the surface of the spherical nozzle. The adjustable angle nozzle 7 is equipped with a posture sensor 71, which realizes precise directional adjustment through feedback data and fine-tuning of the angle by two regulators. When the angle adjustment is completed, the roller brackets of the two regulators are extended to the maximum stroke, and the spherical nozzle is supported in the direction of the ball diameter to achieve the fixation of the adjustable angle nozzle.

[0036] like Figure 7 As shown, embodiment 3 is an adjustable angle flushing nozzle device, and the difference between this embodiment and embodiment 2 is that: the flange seat 8 of this embodiment is provided with an adjuster 1 that can move circumferentially along the flange seat 8. The adjuster 1 can move circumferentially along the ball seat portion 8-3 of the flange seat, so as to be able to perform multi-dimensional universal adjustment on the adjustable angle nozzle.

[0037] As a preferred solution, Figure 8 As shown, the outer ring surface of the flange seat 8 is provided with a guide rail 81 and an arc groove 82, the arc of the arc groove 82 is not less than 90°, and the arc surface of the box seat 101 corresponding to the flange seat 8 is provided with a rail groove 109, and the rail groove 109 cooperates with the guide rail 81 and can slide along the guide rail to achieve stable movement of the box seat. The push rod 102 on the box seat 101 extends into the flange seat 8 through the arc groove 82 to make the friction roller 103 contact the spherical nozzle 7. In this solution, the box seat can be moved along the guide rail by manual or other driving parts, and the purpose of adjusting the angle of the flushing nozzle can be achieved with only one set of guide rails.

[0038] When the box seat uses other driving parts to realize the movement along the guide rail, the specific structure is as follows: Fig. 9 , 10As shown, the guide rail 81 is provided with a rack 83, which is an arc-shaped rack matched with the flange seat and the guide rail. A second motor 110 is provided in the box seat 101, and a driving gear 111 is provided on the output shaft of the second motor 110. The driving gear 111 is meshed with the rack 83. Under the action of the second motor 110, the driving gear 111 drives the box seat 101 to move along the rack 83. The gear changes the direction of the motor torque transmission and has a deceleration function, so that the driving gear rotates, and the driving gear contacts the rack on the flange body guide rail to realize the circumferential movement of the regulator on the flange body. The function of the regulator in this embodiment is the same as that in embodiment 2: that is, it has the function of controlling the rolling of the roller, controlling the push rod to expand and contract slightly in the direction of the ball diameter, and then also has the function of sliding along the guide rail in the circumferential direction of the flange body, thereby realizing the multi-dimensional adjustment of the spherical nozzle by the regulator.
