DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] It should be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it can be directly on the other element or indirectly on the other element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0028] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower, top, bottom", are generally defined as "upper, lower, top, bottom" of the boiler lower slag pipe dredging and protection device in normal use. "Inside and outside" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be an internal connection between two elements or an interaction relationship between two elements; for ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0030] See also Figure 1-Figure 2 The present disclosure provides a boiler lower slag pipe dredging and protection device 100, comprising a support seat 1, a moving wheel 2 and a baffle 3, wherein the moving wheel 2 is located at the bottom of the support seat 1 and is used for rolling contact with the ground, the baffle 3 is movably installed on the support seat 1 along the up and down directions, and the bottom of the baffle 3 can be in contact with the ground or separated from the ground, and the baffle 3 is constructed to be able to prevent the ash falling from the boiler lower slag pipe to the slag falling area from moving toward the legs of the boiler lower slag pipe dredging personnel.

[0031] Through the above technical solution, the moving wheel 2 is located at the bottom of the support seat 1 and is used for rolling contact with the ground. When the slag pipe is unblocked, the boiler slag pipe unblocking personnel can move the boiler slag pipe unblocking protection device 100 to one side of the slag falling area through the moving wheel 2. After the unblocking operation is completed, the boiler slag pipe unblocking protection device 100 can be removed by the moving wheel 2 to avoid the boiler slag pipe unblocking protection device 100 from occupying the working area. Since the baffle 3 is movably mounted on the support seat 1 in the up and down directions, and the bottom of the baffle 3 can be attached to or separated from the ground, when the baffle 3 is attached to the ground, the baffle 3 separates the ash and the legs of the boiler slag pipe unblocking personnel, and blocks the falling ash from moving toward the legs of the unblocking personnel, thereby avoiding the ash from burning and scalding the legs of the unblocking personnel, and effectively ensuring the safety of the work of the boiler slag pipe unblocking personnel.

[0032] Optionally, the movable wheel 2 can be set as a universal wheel, which is conducive to the boiler lower slag pipe dredging protection device 100 to move in any direction, thereby improving the convenience of the boiler lower slag pipe dredging protection device 100.

[0033] Optionally, in order to prevent the high temperature of the ash from affecting or melting the moving wheel 2, the moving wheel 2 can be configured as a high temperature resistant wheel to ensure that the moving wheel 2 can work normally without being affected by the high temperature of the ash.

[0034] In one embodiment provided by the present disclosure, the baffle 3 can be an arc-shaped plate, and the arc mouth of the arc-shaped plate is used to face the slag falling area. On the one hand, the arc-shaped plate can form a semi-enclosed blockage for the slag falling area to prevent the ash from entering the standing area of ​​the dredging personnel from the edge of the baffle 3, effectively protecting the working radius of the dredging personnel. On the other hand, when the dredging personnel use the dredging tool to dredge the boiler slag pipe, the lower end of the dredging tool is easy to contact with the protective device. By setting the arc mouth of the arc-shaped plate to face the slag falling area, the lower end of the dredging tool can be effectively avoided, making the dredging work smoother and improving the work efficiency of the dredging personnel. The curvature of the arc-shaped plate is determined by the specific working environment, and the present disclosure does not limit this.

[0035] In other embodiments, the baffle 3 may also be a straight plate, a V-shaped plate, etc. The present disclosure does not limit the specific shape of the baffle 3.

[0036] Optionally, in order to improve the safety of the dredging personnel, the upper end of the baffle 3 can be arc-shaped. In this way, when the dredging personnel are dredging the boiler slag pipe, if the upper part of the body comes into contact with the upper end of the baffle 3, the sharp upper end of the baffle 3 can be effectively avoided to pose a safety hazard to the dredging personnel.

[0037] It is conceivable that in order to avoid the upper end of the baffle 3 being sharp and causing potential safety hazards, the baffle 3 may be thickened, or an isolation layer, such as cut-resistant fabric, may be arranged on the upper end of the baffle 3 .

[0038] See also Figure 1 and Figure 3 In one embodiment of the present disclosure, the support base 1 includes a base 11 and two mounting rods 12 arranged opposite to each other. The two mounting rods 12 extend in the up-down direction and are connected to the base 11. The moving wheel 2 is arranged at the bottom of the base 11. Figure 1 and Figure 2 The boiler lower slag pipe dredging and protection device 100 also includes two movable sleeves 4 connected to the opposite ends of the baffle 3, the two movable sleeves 4 extend in the up-down direction, and the two movable sleeves 4 are movably sleeved on the mounting rod 12 in the up-down direction respectively, and the baffle 3 is located on the side of the base 11 close to the slag falling area.

[0039] The two movable sleeves 4 are respectively sleeved on the two mounting rods 12, so that the baffle 3 can move in the up and down directions, and the baffle 3 is located on the side of the base 11 close to the slag falling area, which can ensure that the baffle 3 can move downward to a position in contact with the ground, thereby isolating the ash and slag. When the baffle 3 moves upward to the bottom of the baffle 3 and separates from the ground, the baffle 3 does not affect the normal movement of the boiler lower slag pipe dredging protection device 100.

[0040] In another embodiment of the present disclosure, the support seat 1 includes a base 11 and two mounting rods 12 arranged opposite to each other, the two mounting rods 12 extend in the up-down direction and are connected to the base 11, the moving wheel 2 is arranged at the bottom of the base 11, and a slide groove is opened from top to bottom on the side where the two mounting rods 12 are close to each other, the slide groove extends to the bottom of the mounting rod 12, and the baffle 3 enters the slide groove from the slide groove opening. In this way, the baffle 3 is moved in the up-down direction. In the working state, the baffle 3 is inserted into the slide groove until the bottom of the baffle 3 is in contact with the ground to complete the blocking of the ash. In the non-working state, the baffle 3 is pulled out of the slide groove, so as not to affect the movement of the boiler lower slag pipe dredging protection device 100.

[0041] See also Figure 1 and Figure 2 In order to ensure that the baffle 3 can be completely in contact with the ground, optionally, an avoidance notch 41 is formed on both movable sleeves 4, and the avoidance notch 41 is used to avoid the connection between the mounting rod 12 and the base 11, so that the bottom of the baffle 3 can move downward to be in contact with the ground.

[0042] An avoidance notch 41 is provided on the ends of the two movable sleeves 4, and the notch of the avoidance notch 41 is larger than the connection between the mounting rod 12 and the base 11, so as to ensure that the bottom of the movable sleeve 4 will not mechanically interfere with the connection between the mounting rod 12 and the base 11, so that the bottom of the baffle 3 can be completely in contact with the ground, isolating the slag falling area from the working area of ​​the dredging personnel, thereby improving the protection performance of the boiler lower slag pipe dredging protection device 100.

[0043] See also Figure 1-Figure 3 In one embodiment provided in the present disclosure, the boiler lower slag pipe dredging protection device 100 also includes a stop pin 5, a first pin hole 42 is formed on the movable sleeve 4, and a second pin hole 121 is formed on the mounting rod 12. The stop pin 5 can be inserted into the first pin hole 42 and the second pin hole 121 to keep the baffle 3 in a position separated from the ground.

[0044] In this way, when the stop pin 5 is disengaged from the first pin hole 42 and the second pin hole 121, the movable sleeve 4 can move downward along the mounting rod 12, and the bottom of the baffle 3 can fit the ground, thereby realizing isolation and protection of ash slag. When the stop pin 5 is inserted into the first pin hole 42 and the second pin hole 121 on the movable sleeve 4, the stop pin 5 can limit the movement of the movable sleeve 4 in the up and down directions, so that the baffle 3 remains in a position separated from the ground. At this time, when the boiler lower slag pipe dredging and protection device 100 is moved, the baffle 3 will not rub against the ground, thereby affecting the movement of the boiler lower slag pipe dredging and protection device 100.

[0045] Optionally, the mounting rod 12 is inclined in a direction away from the slag falling area, and the angle between the mounting rod 12 and the horizontal plane is 75° to 85°. The mounting rod 12 is set to be inclined in a direction away from the slag falling area. On the one hand, the movable sleeve 4 is sleeved on the mounting rod 12, and the mounting rod 12 is inclined in a direction away from the slag falling area, so that the baffle 3 can also be inclined in a direction away from the slag falling area, so that the center of gravity of the boiler lower slag pipe dredging protection device 100 is closer to the side away from the slag falling area, effectively improving the stability of the boiler lower slag pipe dredging protection device 100, and preventing the boiler lower slag pipe dredging protection device 100 from tipping over toward the slag falling area when the dredging personnel dredge the boiler lower slag pipe. On the other hand, the angle between the mounting rod 12 and the horizontal plane is set to 75° to 85°, which can prevent the baffle 3 with a too small inclination angle from affecting the normal work of the dredging personnel.

[0046] See also Figure 3 Optionally, the base 11 includes a connecting rod 111 and two supporting rods 112, the two supporting rods 112 are located on the side of the connecting rod 111 away from the baffle 3, the two supporting rods 112 are respectively connected to the two ends of the connecting rod 111 and extend from the connecting rod 111 in a direction away from the baffle 3, the connecting rod 111 and the two supporting rods 112 are located in the same horizontal plane, and the mounting rod 12 is connected to the connecting rod 111.

[0047] The base 11 includes a connecting rod 111 and two supporting rods 112. The moving wheel 2 is installed at the bottom of the supporting rod 112. The connecting rod 111 and the two supporting rods 112 are all located in the same horizontal plane, ensuring that the moving wheel 2 is also in the same horizontal plane. The boiler lower slag pipe dredging protection device 100 can move normally. In addition, the base 11 is formed only by connecting the two supporting rods 112 and the connecting rod 111, which can improve the stability of the base 11 and effectively reduce the manufacturing cost of the boiler lower slag pipe dredging protection device 100. At the same time, the structure of the base 11 is simple and reliable, and it is easy to maintain.

[0048] Optionally, a bottom plate may be provided between two support rods 112 located in the same horizontal plane, and the dredging personnel may dredge the slag pipe by standing on the bottom plate.

[0049] Optionally, the baffle plate 3 is an arc-shaped plate, the arc opening of the arc-shaped plate is used to face the slag falling area, and the connecting rod 111 is formed as a curved rod with the same curvature as the arc-shaped plate. The connecting rod 111 is formed as a curved rod with the same curvature as the arc-shaped plate, which can avoid a large gap between the connecting rod 111 and the baffle plate 3, making the overall structure of the boiler lower slag pipe dredging protection device 100 more compact.

[0050] In order to prevent the baffle 3 from conducting heat and affecting or scalding the dredging personnel, in one embodiment provided in the present disclosure, a heat insulating pad (not shown) is attached to the surface of the baffle 3 away from the slag falling area. With such a configuration, when the dredging personnel dredge the slag pipe, if the body of the dredging personnel comes into contact with the baffle 3, it can be prevented that the temperature of the baffle 3 rises due to the high temperature of the ash and slag, thereby affecting or scalding the dredging personnel.

[0051] In another embodiment provided in the present disclosure, the baffle 3 can be set as a heat insulation board. By setting the baffle 3 as a heat insulation board, the temperature of the baffle 3 can be prevented from rising and affecting or scalding the dredging personnel.

[0052] In order to ensure the protective effect of the baffle 3, optionally, the height of the baffle 3 can be 700mm-900mm. The baffle 3 with a height of 700mm-900mm can effectively protect the lower part of the body of the dredging personnel without affecting the normal work of the dredging personnel.

[0053] See also Figure 1-Figure 3 In one embodiment of the present disclosure, the boiler lower slag pipe dredging protection device 100 also includes a connecting plate 6, which is arranged between the mounting rod 12 and the support rod 112. By arranging the connecting plate 6 between the mounting rod 12 and the support rod 112, the structural strength between the mounting rod 12 and the support rod 112 can be effectively improved.
