Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to an ash dish clamping device. Background Art

[0002] Fire assaying is an important method for analyzing gold and silver content in ores and metallurgical products due to its representative sampling, wide applicability, and accurate and reliable results. The most commonly used fire assay is the lead assay. The lead assay completes the analysis of gold and silver content through four stages: batching, melting, ash blowing, and gold separation. Ash blowing is a key method for separating lead from gold and silver in the lead assay. It also removes impurities that enter the lead buckle during the melting stage, facilitating the determination of gold and silver.

[0003] Fire assaying requires the use of an ash tray during the ash blowing stage, but the ash tray becomes brittle and easily broken after being preheated at high temperature. When measuring the amount of silver, the ash tray needs to be taken out after the ash blowing is completed to reduce the loss of silver during the ash blowing. During the ash blowing, poor control of the ash blowing temperature and the size of the ash blowing furnace door opening will cause the ash to freeze, and the ash tray needs to be taken out and lead foil added for a second ash blowing. The above operation requires the ash tray clamp to be clamped and removed from the ash blowing furnace. When clamping the ash tray with the existing ash tray clamp, the ash tray needs to be held by hand, and the clamping force needs to be manually controlled. If too much force is used during clamping, the ash tray is prone to breakage. When moving the ash tray out of the ash blowing furnace, the clamping force of the ash tray is weak and the ash tray is easy to fall, making it inconvenient to move the ash tray.

[0004] In summary, it is necessary to design an improved ash dish clamping device to solve the above problems. Utility Model Content

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] An ash dish clamping device, comprising:

[0007] The ash dish clamp comprises two clamps and a connecting rod provided on the surface of each clamp, wherein the clamp is an arc-shaped sheet structure as a whole;

[0008] The force control component includes an elastic driving part provided on the surface of the connecting rod, a gripping handle provided on the surface of the elastic driving part, and a speed limiting part connecting the gripping handle and the connecting rod. The elastic driving part can provide the connecting rod with a force to drive the two clamps to approach each other. When the speed limiting part is moved toward the direction of the clamps, the clamps on the connecting rod are restricted from approaching each other. When the speed limiting part is moved toward the direction away from the clamps, the clamps on the connecting part are restricted from moving away from each other.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the elastic driving part includes a movable shell provided on the surface of the connecting rod and an elastic part provided inside the movable shell. The surface of the movable shell is provided with a sliding groove adapted to the connecting rod, and the connecting rod can pass through the entire movable shell from the inside of the sliding groove.

[0011] Furthermore, the gripping handle is connected to the surface of the movable housing, and the end of the connecting rod close to the gripping handle is tilted as a whole.

[0012] Furthermore, the speed limiting part includes a movable sleeve provided on the gripping handle and the connecting rod, and a connecting piece connecting all the movable sleeves together.

[0013] Furthermore, a limiting plate is provided on the surface of the connecting rod, and the limiting plate is in contact with the outer surface of the movable shell.

[0014] Furthermore, a connecting plate is provided on the surface of the connecting rod located inside the movable shell, and the connecting plate is connected to the elastic member.

[0015] Furthermore, a sliding connection ball is provided between the connecting plate and the movable shell, a sliding groove adapted to the sliding connection ball is provided inside the movable shell, and a groove capable of accommodating the sliding connection ball is provided on the surface of the connecting plate.

[0016] Furthermore, a control handle is provided on the surface of the movable sleeve located on the gripping handle, and a sliding limiting structure is provided between the gripping handle and the control handle.

[0017] Furthermore, the sliding limiting structure includes a limiting block provided on the surface of the gripping handle, and a slot provided on the surface of the control handle and adapted to the limiting block.

[0018] Furthermore, a telescopic rod is provided at one end of the gripping handle away from the clamping head, and an extension rod is provided at one end of the control handle close to the telescopic rod.

[0019] Beneficial effects

[0020] Compared with the prior art, the present invention can, through the force control component, limit the movement of the connecting rod by the speed limiting part when the ash pan needs to be clamped, so as to ensure that the clamps will not close. When the operator moves the clamps near the ash pan, the speed limiting part controls the clamps to slowly close, thereby clamping the ash pan. The clamping force is controlled by pushing, so that the ash pan will not be suddenly broken by a large force. At the same time, during the operation, the operator's hand does not directly contact the connecting rod and will not directly exert force on the ash pan, reducing the damage of the ash pan caused by human factors such as improper force control.

[0029] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] See also Figure 1-5 The ash dish clamping device of the present invention includes an ash dish clamp 1 and a force control component 2 capable of controlling the clamping force of the ash dish clamp 1.

[0032] Among them, the ashtray clamp 1 includes two clamps 11 and a connecting rod 12 provided on the surface of each clamp 11. The clamp 11 is an arc-shaped sheet structure as a whole. The clamp 11 as a whole can be an arc shape covering 1 / 4 of the ashtray. The length is slightly longer than the ashtray, which can better wrap the ashtray, increase the force-bearing area, and further reduce the probability of the ashtray being broken due to force. The connecting rod 12 is a rod-shaped structure as a whole.

[0033] In some embodiments, the force control component 2 includes an elastic driving portion 21 provided on the surface of the connecting rod 12, a gripping handle 22 provided on the surface of the elastic driving portion 21, and a speed limiting portion 23 connecting the gripping handle 22 and the connecting rod 12. The elastic driving portion 21 can provide the connecting rod 12 with a force to drive the two chucks 11 to approach each other. When the speed limiting portion 23 is moved toward the direction of the chuck 11, the chucks 11 on the limiting connecting rod 12 can approach each other. When the speed limiting portion 23 is moved toward the direction away from the chuck 11, the chucks 11 on the limiting connecting member 232 can move away from each other.

[0034] It should be noted that in order to realize the driving of the connecting rod 12 by the elastic driving part 21, the elastic driving part 21 includes a movable shell 211 arranged on the surface of the connecting rod 12, and an elastic part 212 arranged inside the movable shell 211. The surface of the movable shell 211 is provided with a sliding groove adapted to the connecting rod 12. The connecting rod 12 can pass through the entire movable shell 211 from the inside of the sliding groove, and the gripping handle 22 is connected to the surface of the movable shell 211.

[0035] In some embodiments, the end of the connecting rod 12 close to the gripping handle 22 is tilted as a whole, and the speed limiting portion 23 includes a movable sleeve 231 provided on the gripping handle 22 and the connecting rod 12, and a connecting member 232 connecting all the movable sleeves 231 together. By pushing the movable sleeve 231, a portion of the tilted connecting rod 12 can be caused to translate inside the elastic driving portion 21.

[0036] Furthermore, in order to achieve smooth movement of the connecting rod 12 inside the movable shell 211, a limiting plate 213 is provided on the surface of the connecting rod 12, and the limiting plate 213 is in contact with the outer surface of the movable shell 211. The surface of the connecting rod 12 located inside the movable shell 211 is provided with a connecting plate 214, and the connecting plate 214 is connected to the elastic member 212. A sliding connecting ball 215 is provided between the connecting plate 214 and the movable shell 211, and a sliding groove adapted to the sliding connecting ball 215 is provided inside the movable shell 211. A groove capable of accommodating the sliding connecting ball 215 is provided on the surface of the connecting plate 214, and a control handle 24 is provided on the surface of the movable sleeve 231 located on the grasping handle 22, and a sliding limiting structure 25 is provided between the grasping handle 22 and the control handle 24.

[0037] In some embodiments, the sliding limit structure 25 includes a limit block provided on the surface of the gripping handle 22 and a slot provided on the surface of the control handle 24 that matches the limit block. The gripping handle 22 is provided with a telescopic rod 3 at the end away from the clamping head 11, and the control handle 24 is provided with an extension rod at the end close to the telescopic rod 3. The telescopic design can meet the needs of operating ash blowing furnaces of different depths. The clamping piece is relatively thin and designed to be perpendicular to the ash pan, so any ash pan can be clamped without moving other ash pans and will not affect other ash pans.

[0038] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly.
