Description

Technical Field

[0001] The utility model relates to the technical field of dummy bar storage trolleys, and relates to a reliable positioning device for dummy bar storage trolleys. Background Art

[0002] The dummy bar storage trolley is mainly used for storing and managing the dummy bar, and is an indispensable device in the continuous casting machine. When the site space is limited, a down-feed type dummy bar chain storage device is usually used for efficient storage and management of the dummy bar;

[0003] At present, for the down-feed type dummy bar chain storage device, it is basically controlled by electrical cam limit. During the centering process of the dummy bar, the storage and recovery of the dummy bar are all manual. The operator who adjusts the position of the dummy bar chain moves frequently on the track of the dummy bar storage trolley. Operator's misoperation, motor brake failure, chain breakage due to external force impact, etc. will cause the dummy bar trolley to suddenly slide down, causing harm to the operators on the lower track, and there are safety hazards. This design is not comprehensive;

[0004] To solve the above problems, a reliable positioning device for the dummy bar storage trolley is proposed in this application. Content of the Utility Model

A chain is fixedly connected to the top of the positioning frame. One end of the chain is provided with a positioning structure. The positioning structure includes a first through hole opened on the positioning frame. The positioning frame is movably connected with a positioning pin through the first through hole. A second through hole is opened on the dummy bar trolley. The bottom of the positioning pin passes through the second through hole opened on the dummy bar trolley. A fixed tube is hinged to the outer wall of the bottom of the positioning pin. A first spring is fixedly connected to the inside of the fixed tube. One end of the first spring is fixedly connected with a movable rod. One end of the movable rod is hinged with an arc-shaped plate. A connecting rod is fixedly connected to the outer wall of the bottom of the positioning pin. One end of the connecting rod is hinged with the arc-shaped plate.

[0007] A pushing structure is arranged at the bottom of the dummy bar trolley. The pushing structure includes a connecting plate fixedly connected to the bottom of the dummy bar trolley. A threaded rod is threadedly connected to the connecting plate. One end of the threaded rod close to the arc-shaped plate is rotatably connected with a pushing block. The top of the pushing block is attached to the bottom of the dummy bar trolley. By setting the pushing structure, the extrusion of the arc-shaped plate is realized.

[0008] One end of the dummy bar carriage is fixedly connected with an inclined block. A chute is formed at the top of the dummy bar carriage at one end of the inclined block. The chute formed in the dummy bar carriage is fixedly communicated with a second through hole formed in the dummy bar carriage. By providing the inclined block and the chute, the pushing of the positioning pin is realized.

[0009] The bottom of the positioning frame is fixedly connected with a second spring. One end of the second spring is fixedly connected with an extension rod. A connecting ring is fixedly connected to the outer wall of the positioning pin. The connecting ring is fixedly connected with the extension rod. By providing the second spring, the extension rod and the connecting ring, the rapid pushing of the positioning pin is realized, thereby avoiding affecting the positioning effect on the dummy bar storage carriage.

[0010] A limiting strip is fixedly connected to the outer wall of the positioning pin. The limiting strip is slidably connected with the positioning frame. By providing the limiting strip, the limiting of the positioning pin is realized, thereby avoiding the detachment and movement of the dummy bar storage carriage.

[0011] The bottom of the dummy bar carriage is fixedly connected with a baffle. One side of the baffle is attached to one side of the push block. By providing the baffle, the limiting of the push block is realized, thereby avoiding affecting the clamping and limiting effect of the push block on the arc-shaped plate.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By providing a positioning structure, the positioning effect on the dummy bar storage carriage is realized. By inserting the positioning pin into the first through hole and the second through hole, the unsafe state of the dummy bar storage carriage at the storage position is avoided, and the reliability and safety of storage are enhanced, thereby avoiding a series of accidents caused by misoperations, etc.

[0014] By providing a pushing structure, the extrusion of the arc-shaped plate is realized. When the staff needs to move the positioning pin out of the range of the second through hole, the arc-shaped plate can be clamped and limited by the push block, so that it is convenient for the staff to pull the positioning pin out of the range of the second through hole through the chain, thereby avoiding affecting the working efficiency of the dummy bar storage carriage.

[0027] Refer to Figures 1-3, The dummy bar storage trolley reliable positioning device includes a positioning frame 1 and a dummy bar trolley 2 movably connected to the positioning frame 1. The dummy bar trolley 2 is used to transport the dummy bar. A chain 3 is fixedly connected to the top of the positioning frame 1. A positioning structure 4 is provided at one end of the chain 3. The positioning structure 4 includes a first through hole 407 opened on the positioning frame 1. The positioning frame 1 is movably connected with a positioning pin 401 through the first through hole 407. One end of the positioning pin 401 is fixed to the chain 3 to prevent the positioning pin 401 from being lost. A second through hole 408 is opened on the dummy bar trolley 2. By inserting the positioning pin 401 into the first through hole 407 and the second through hole 408, the dummy bar trolley 2 is connected to the positioning frame 1, increasing the stability of the dummy bar trolley 2. The bottom of the positioning pin 401 passes through the second through hole 408 opened on the dummy bar trolley 2. A fixed tube 402 is hinged to the outer wall of the bottom of the positioning pin 401. A first spring 403 is fixedly connected inside the fixed tube 402. The fixed tube 402 is used to limit the first spring 403. One end of the first spring 403 is fixedly connected to a movable rod 404. The first spring 403 is used to realize the telescopic movement of the movable rod 404. One end of the movable rod 404 is hinged to an arc-shaped plate 405. The movable rod 404 is used to realize the movement and flipping of the position of the arc-shaped plate 405. A connecting rod 406 is fixedly connected to the outer wall of the bottom of the positioning pin 401. The connecting rod 406 is used to limit the arc-shaped plate 405. One end of the connecting rod 406 is hinged to the arc-shaped plate 405.

[0028] Refer to Figure 1 and Figure 4 , A pushing structure 5 is provided at the bottom of the dummy bar trolley 2. The pushing structure 5 includes a connecting plate 501 fixedly connected to the bottom of the dummy bar trolley 2. A threaded rod 502 is threadedly connected to the connecting plate 501. The connecting plate 501 is used to connect the threaded rod 502 to the bottom of the dummy bar trolley 2 and at the same time realize the rotational extension of the threaded rod 502. One end of the threaded rod 502 close to the arc-shaped plate 405 is rotatably connected with a push block 503. The threaded rod 502 is used to realize the extension of the push block 503. By the extension of the push block 503, the arc-shaped plate 405 is squeezed, so as to facilitate the staff to pull the positioning pin 401. The top of the push block 503 is in contact with the bottom of the dummy bar trolley 2.

[0029] Refer to Figure 2 and Figure 3, one end of the dummy bar carriage 2 is fixedly connected with an inclined block 6. The inclined block 6 is used to lift the positioning pin 401. A chute 7 is opened at the top of one end of the dummy bar carriage 2 where the inclined block 6 is located. The chute 7 is used to limit the positioning pin 401. The chute 7 opened on the dummy bar carriage 2 is fixedly communicated with the second through hole 408 opened on the dummy bar carriage 2. The combined use of the inclined block 6 and the chute 7 can realize the pushing of the positioning pin 401. When the dummy bar carriage 2 is connected to the positioning frame 1, the inclined block 6 and the chute 7 are used to lift the positioning pin 401 during the movement of the dummy bar carriage 2, so that the positioning pin 401 naturally falls into the interior of the second through hole 408, thereby reducing the operation of the staff.

[0030] Refer to Figure 2 and Figure 3 , a second spring 8 is fixedly connected to the bottom of the positioning frame 1. One end of the second spring 8 is fixedly connected with an extension rod 9. The second spring 8 is used to connect the extension rod 9 to the positioning frame 1 and simultaneously realize the compression and extension of the extension rod 9. A connecting ring 10 is fixedly connected to the outer wall of the positioning pin 401. The connecting ring 10 is fixedly connected with the extension rod 9. The connection between the connecting ring 10 and the extension rod 9 is used to realize the control of the second spring 8 over the connecting ring 10 and the positioning pin 401. The combined use of the second spring 8, the extension rod 9 and the connecting ring 10 can realize the rapid pushing of the positioning pin 401, avoiding the arc-shaped plate 405 being clamped into the interior of the second through hole 408 under the action of the first spring 403 when the positioning pin 401 falls naturally, thereby avoiding affecting the positioning effect of the dummy bar storage carriage.

[0031] Refer to Figure 2 and Figure 3 , a limiting strip 11 is fixedly connected to the outer wall of the positioning pin 401. The limiting strip 11 is slidably connected with the positioning frame 1. There are two limiting strips 11 for the dummy bar carriage 2, respectively located on both sides of the positioning pin 401. The limiting strip 11 is used to limit the positioning pin 401, avoiding the positioning pin 401 rotating inside the first through hole 407, thereby avoiding affecting the insertion of the positioning pin 401 into the second through hole 408 and thus avoiding the detachment and movement of the dummy bar storage carriage.

[0032] Refer to Figure 3 and Figure 4 , a baffle 12 is fixedly connected to the bottom of the dummy bar carriage 2. One side of the baffle 12 is in contact with one side of the push block 503. There are two baffles 12, respectively located on both sides of the threaded rod 502. The baffle 12 is used to limit the push block 503, avoiding the staff rotating the threaded rod 502 to turn the push block 503 to a range relatively far from the arc-shaped plate 405, thereby avoiding affecting the clamping and limiting effect of the push block 503 on the arc-shaped plate 405.

[0033] Working principle:

[0034] The reliable positioning device for the dummy bar storage trolley. When the dummy bar trolley 2 loaded with the dummy bar moves to the positioning frame 1, during the movement, the inclined block 6 pushes the positioning pin 401, causing the positioning pin 401 to rise. During the continuous movement of the dummy bar trolley 2, the positioning pin 401 is inserted into the interior of the second through hole 408 under the action of the second spring 8. At the same time, the arc plate 405 expands and flips under the action of the first spring 403, thereby realizing the fixation of the position of the dummy bar trolley 2. After the dummy bar trolley 2 finishes working, the staff rotates the threaded rod 502 to move the push block 503, and the push block 503 squeezes the arc plate 405, so as to avoid affecting the range where the staff pulls out the positioning pin 401 from the second through hole 408, thus avoiding affecting the work efficiency.
