Description

Helper handle and slag removal device Technical Field

[0001] This utility model relates to the field of slag removal device technology, and in particular to an assistive handle and a slag removal device. Background Technology

[0002] During the operation of a circulating fluidized bed boiler, slag accumulation can occur due to improper operating condition adjustments, boiler coking, deterioration of coal quality, and excessively large coal or bottom ash particles. Currently, steel bars are commonly used as slag-clearing devices. Operators manually move the steel bars up and down through the slag discharge pipe of the circulating fluidized bed boiler's slag cooler to clear the blockage. However, this method of directly using steel bars for slag clearing is inconvenient, as it presents difficulties in applying force, increases the risk of operator fatigue and injury, and is therefore quite cumbersome. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an assist handle and a slag-clearing device, which aims to improve the ease of operation of the slag-clearing device.

[0004] To achieve the above objectives, this utility model provides an auxiliary handle for a slag-clearing device, comprising:

[0005] An installation component having a connecting channel formed within it for a reinforcing bar to pass through, the connecting channel extending through the installation component, and the installation component being detachably connected to the reinforcing bar; and

[0009] A fastener, at least a portion of which is movably disposed through the through hole and at least a portion of which is capable of extending into the connecting channel, such that the fastener can switch between a locked state and a released state. When the fastener is in the locked state, one end of the fastener abuts against the reinforcing bar, thereby locking the reinforcing bar within the connecting channel. When the fastener is in the released state, one end of the fastener disengages from the reinforcing bar, thereby allowing the reinforcing bar to exit the connecting channel.

[0010] In one embodiment, a fixing member is provided on the outer periphery of the sleeve, and the fixing member is provided with a threaded hole opposite to the through hole. The fastener is sequentially inserted into the threaded hole and the through hole and is threadedly engaged with the fixing member.

[0011] In one embodiment, the end of the fastener away from the reinforcing bar is provided with an adjustment structure, which is used to drive the fastener to rotate relative to the fixing member under the action of an external force.

[0012] In one embodiment, the fastener is tapered at the end facing the reinforcing bar.

[0013] In one embodiment, the gripping component includes:

[0014] The main body is spaced apart on the periphery of the mounting component; and

[0015] Two connecting parts are respectively located at both ends of the main body and connected between the main body and the mounting component.

[0016] In one embodiment, at least one of the connecting portions is provided with a buffer structure, at least a portion of which is located within the gripping space.

[0017] In one embodiment, the outer peripheral surface of the main body is provided with an anti-slip structure.

[0018] This utility model also proposes a slag-clearing device, including a steel bar and an assist handle as described in any of the preceding claims, wherein the assist handle is mounted on the steel bar and is detachably connected to the steel bar.

Detailed Implementation

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] It should be understood that the terms "before" and "after" are used in this utility model to describe various types of information, but these terms should not be limited to them. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this utility model.

[0028] As shown in Figures 1 to 3, the auxiliary handle 10 of a slag-clearing device 100 according to an embodiment of the present invention includes an installation component 11 and a gripping component 12. The installation component 11 has a connecting channel 111a for a reinforcing bar 20 to pass through. The connecting channel 111a passes through the installation component 11 and is detachably connected to the reinforcing bar 20. The gripping component 12 is located around the installation component 11 and forms a gripping space with the installation component 11.

[0029] The reinforcing bar 20 can be a solid reinforcing bar rod, used to extend into the slag lower pipe of the circulating fluidized bed boiler and move up and down to clear the slag lower pipe. The mounting component 11 serves as the mounting base for the assist handle 10, and has a connecting channel 111a formed therein. At least one end of the connecting channel 111a is open to allow the reinforcing bar 20 to extend into the connecting channel 111a and connect with the mounting component 11. The gripping component 12 can be welded to the mounting component 11 to ensure the stability of the connection between the gripping component 12 and the mounting component 11. In some embodiments, the connecting channel 111a may be through-through at one end, so that the end of the reinforcing bar 20 passes through the through end of the connecting channel 111a and enters the connecting channel 111a. In this case, the mounting component 11 can be connected and fixed to the end of the reinforcing bar 20. In other embodiments, the connecting channel 111a may also be through-through at both ends, so that the reinforcing bar 20 can pass through either end of the connecting channel 111a. In this case, the mounting component 11 can be connected and fixed to the end or middle of the reinforcing bar 20 according to the usage requirements, and there is no limitation here.

[0030] It is understood that the technical solution of this utility model, by forming a connecting channel 111a for the steel bar 20 to pass through in the mounting component 11 and detachably connecting it with the steel bar 20, allows the auxiliary handle 10 to be mounted on the steel bar 20 used for slag removal through the mounting component 11; by setting the gripping component 12 on the periphery of the mounting component 11 and forming a gripping space with the mounting component 11, the auxiliary handle 10 can be easily gripped and forceped by the user, thereby improving the ease of operation of the slag removal device 100.

[0031] As shown in Figures 2 and 3, the installation component 11 of this embodiment includes a sleeve 111 and a fastener 112. A connecting channel 111a is formed inside the sleeve 111, and a through hole 111b communicating with the connecting channel 111a is provided on the outer periphery of the sleeve 111. The fastener 112 is movably inserted through the through hole 111b and can at least partially extend into the connecting channel 111a, so that the fastener 112 can switch between a locked state and a released state. When the fastener 112 is in the locked state, one end of the fastener 112 abuts against the reinforcing bar 20, so that the reinforcing bar 20 can be locked in the connecting channel 111a. When the fastener 112 is in the released state, one end of the fastener 112 disengages from the reinforcing bar 20, so that the reinforcing bar 20 can be released from the connecting channel 111a.

[0032] With this configuration, the reinforcing bar 20 can be locked to the assist handle 10 or moved relative to the assist handle 10 by switching the locked and released states of the fastener 112. When it is necessary to adjust the position of the assist handle 10 on the reinforcing bar 20, the fastener 112 can be switched to the released state to unlock the reinforcing bar 20 and the assist handle 10. Then, according to the actual required length of slag removal for the reinforcing bar 20, the assist handle 10 can be slidably adjusted relative to the reinforcing bar 20 to a suitable position. Finally, the fastener 112 can be switched to the locked state to fix the reinforcing bar 20 and the assist handle 10 to each other. This allows for flexible adjustment of the position of the assist handle 10 and improves the usability of the assist handle 10.

[0033] As shown in Figure 3, the outer periphery of the sleeve 111 in this embodiment of the present invention is provided with a fixing member 113. The fixing member 113 is provided with a screw hole that is opposite to the through hole 111b. The fastener 112 is sequentially inserted into the screw hole and the through hole 111b and is threadedly engaged with the fixing member 113.

[0034] Specifically, in this embodiment, the fixing member 113 can be configured as a nut, which is fixedly connected to the outer periphery of the sleeve 111. The portion of the fastener 112 passing through the screw hole and the through hole 111b can be configured as a screw rod, and the screw rod portion of the fastener 112 can be threadedly engaged with the screw hole of the fixing member 113. With this configuration, when the fastener 112 rotates forward relative to the fixing member 113 about its axial direction, the end of the fastener 112 facing the reinforcing bar 20 can gradually move closer to the reinforcing bar 20 as the fastener 112 rotates; when the fastener 112 rotates in the opposite direction relative to the fixing member 113 along its axial direction, the end of the fastener 112 away from the reinforcing bar 20 can gradually move away from the reinforcing bar 20 as the fastener 112 rotates. Thus, by controlling the fastener 112 to rotate forward or in the opposite direction, the fastener 112 can be switched between a locked state and a released state.

[0035] As shown in Figure 3, the fastener 112 of this embodiment of the present invention has an adjustment structure 112a at the end away from the reinforcing bar 20. The adjustment structure 112a is used to drive the fastener 112 to rotate relative to the fixing member 113 under the action of external force. Specifically, the adjustment structure 112a can be set as a screw head, which can be used to connect an external screwdriver or other adjustment tool. The user can drive the adjustment structure 112a to rotate by adjusting the tool, so that the screw part on the fastener 112 rotates relative to the screw hole of the fixing member 113, thereby causing the fastener 112 to gradually move closer to or away from the reinforcing bar 20 in the connecting channel 111a as it rotates. Of course, the technical solution of this invention is not limited to this. In other embodiments, the user can also directly hold the adjustment structure 112a by hand to drive the mechanism 112 to rotate relative to the fixing member 113, which is not limited here.

[0036] The outer diameter of the adjusting structure 112a can be larger than the inner diameter of the screw hole. With this setting, the fastener 112 can also be restricted from excessive displacement into the connecting channel 111a by adjusting the structure 112a.

[0037] As shown in Figure 3, the fastener 112 of this embodiment is tapered at one end facing the reinforcing bar 20. This tapered end serves as a guide, facilitating the alignment of the fastener 112 with the screw hole of the fixing member 113 and the through hole 111b on the mounting component 11.

[0038] As shown in Figure 3, the inner diameter of the connecting channel 111a in this embodiment of the present invention is larger than the outer diameter of the reinforcing bar 20. Specifically, in this embodiment, the reinforcing bar 20 can be a solid reinforcing bar rod with an outer diameter ranging from 10mm to 12mm, specifically 10mm, 11mm, 12mm, or any value between 10mm and 12mm. By making the inner diameter of the connecting channel 111a slightly larger than the outer diameter of the reinforcing bar 20, it is easier to insert the reinforcing bar 20 into the connecting channel 111a and connect it with the mounting component 11.

[0039] As shown in Figures 2 and 3, the gripping component 12 of this utility model embodiment includes a main body 121 and two connecting parts 122. The main body 121 is spaced apart on the periphery of the mounting component 11. The two connecting parts 122 are respectively disposed at both ends of the main body 121 and connected between the main body 121 and the mounting component 11, thereby cooperating with the main body 121 and the mounting component 11 to form a gripping space.

[0040] Specifically, in this embodiment, the main body 121 can be configured as a straight strip extending along the length of the reinforcing bar 20, and the two connecting parts 122 can be arranged in an arc shape and bent and connected between the two ends of the main body 121 and the mounting component 11, respectively. With this configuration, the gripping component 12 can be an arched structure as a whole, and together with the mounting component 11, it forms a gripping space, so that the user can grip and apply force to the power handle 10.

[0041] As shown in Figures 2 and 3, at least one connecting part 122 of this embodiment of the present invention is provided with a buffer structure 122a, and at least a portion of the buffer structure 122a is located within the gripping space.

[0042] Specifically, in this embodiment, the reinforcing bar 20 has a slag-pouring end for reciprocating up-and-down movement within the slag-feeding pipe of the circulating fluidized bed boiler's slag cooler. When the assist handle 10 is installed on the reinforcing bar 20, the two connecting portions 122 of the gripping component 12 are sequentially spaced along the length of the reinforcing bar 20. The buffer structure 122a can be provided on one connecting portion 122 near the slag-pouring end of the reinforcing bar 20 and cover the side of that connecting portion 122 facing the other connecting portion 122. Of course, the technical solution of this utility model is not limited to this. In other embodiments, the buffer structure 122a can wrap around the periphery of the connecting portion 122; both connecting portions 122 can be provided with the buffer structure 122a, which is not limited here.

[0043] The buffer structure 122a can be, but is not limited to, made of rubber or other elastic materials. By providing the buffer structure 122a on the connecting part 122 and ensuring that at least a portion of the buffer structure 122a is located within the grip space, the buffer structure 122a acts as a spacer between the connecting part 122 and the user's hand. With this configuration, when the user encounters significant resistance during slag removal, the reinforcing bar 20 will generate an impact force on the assist handle 10. The buffer structure 122a can effectively absorb and buffer this impact force, reducing vibration injury to the user's hand and ensuring both comfort and safety during slag removal.

[0044] As shown in Figure 3, the outer peripheral surface of the main body 121 of this utility model embodiment is provided with an anti-slip structure 121a.

[0045] Specifically, in this embodiment, the outer peripheral surface of the main body 121 may be provided with anti-slip patterns to increase the friction between the user and the main body 121 when the user holds the assist handle 10, thereby helping to prevent the user's hand from slipping during the slag removal operation. This allows the assist handle 10 to achieve a better anti-slip effect and ensures the safety of the slag removal operation.

[0046] Of course, the technical solution of this utility model is not limited to this. In other embodiments, an anti-slip layer may be covered on the outer peripheral surface of the main body 121. The material of the anti-slip layer may be, but is not limited to, rubber. Such a design can also increase the friction between the user's grip on the power handle 10 and the main body 121, achieving a better anti-slip effect.

[0047] This utility model also proposes a slag-clearing device 100, which includes a steel bar 20 and an auxiliary handle 10. The specific structure of the auxiliary handle 10 is as described in the above embodiments. Since this slag-clearing device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0048] The working process of this utility model is as follows: First, according to the diameter of the slag-clearing steel bar 20, adjust the relative position of the fastener 112 and the sleeve 111 in the installation component 11 so that the steel bar 20 can be smoothly inserted into the connecting channel 111a of the sleeve 111; then, when the insertion length of the steel bar 20 meets the requirements of the slag-clearing operation, switch the fastener 112 from the released state to the locked state so that the steel bar 20 is locked to the sleeve 111 through the fastener 112 and will not slide relative to the installation component 11 during the slag-clearing operation, thereby achieving stable installation of the power handle 10.

[0049] After the assist handle 10 is installed on the rebar 20, the user holds at least one hand on the assist handle 10. Specifically, one hand can hold the gripping part 12 of the assist handle 10, while the other hand holds the rebar 20. In other embodiments, both hands can hold the same assist handle 10 simultaneously, or two assist handles 10 can be provided on the rebar 20 for the user to hold with both hands respectively; this is not limited here. When performing the slag removal operation, the user applies force with both hands simultaneously. Compared to the traditional method of directly holding the rebar 20 with one hand, this utility model, by adding the assist handle 10 to the rebar 20, can utilize the greater additional force provided by the assist handle 10 to make it easier for the rebar 20 to be inserted into the slag accumulation area and to perform the slag removal operation, which is beneficial to improving the convenience and efficiency of the slag removal operation.

[0050] In addition, after the power handle 10 is installed on the rebar 20, if it is necessary to readjust the position of the power handle 10 on the rebar 20, the fastener 112 of the power handle 10 can be switched from the locked state to the released state first, and then the relative position between the rebar 20 and the power handle 10 can be adjusted. After the power handle 10 slides to a suitable position relative to the rebar 20, it can be switched back to the locked state.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
