Description

Technical Field

[0001] The invention relates to the technical field of continuous beam construction, in particular to an integral mold dropping device. Background Art

[0002] During the construction of the continuous beam of the bridge, a forming mold for concrete molding needs to be set up. The existing continuous beam forming mold includes a side mold and a bottom mold. After the continuous beam construction is completed, the forming mold located at high altitude needs to be dismantled.

[0003] In the prior art, when dismantling the bottom formwork, the bottom end of the steel strand is usually connected to the bottom formwork using an anchor, and then the top of the steel strand is connected to the through-type jack located on the bridge deck using two anchors. Subsequently, the opening and closing of the two anchors are repeatedly adjusted and the through-type jack is reciprocatedly raised and lowered to complete the lowering of the bottom formwork.

[0004] However, after actual application by technical personnel in this field, it was found that the above-mentioned removal method still has some shortcomings. The most obvious one is that during the reciprocating lifting of the through-type jack, the operator needs to manually open and close the two anchors located above and below the through-type jack to complete the locking and unlocking of the steel strand. The overall operation process is relatively cumbersome and labor-intensive, and it also has a great impact on the lowering efficiency of the bottom mold.

[0005] Therefore, it is necessary to invent an integral die dropping device to solve the above problems. Summary of the invention

Drive, first make the limit mechanism release the limit on the lower locking mechanism, then make the lower locking mechanism lock the lower section of the steel strand, so that the subsequent through-type jack can drive the upper locking mechanism to move up and reset, and then complete the mold drop operation after repeating the above operation for many times, so as to solve the problem proposed in the above background technology that during the reciprocating lifting process of the through-type jack, the operator needs to manually open and close the two anchors located above and below the through-type jack to complete the locking and unlocking of the steel strand.

The guide block is fixedly set on the top of the adjacent triangular limit groove.

[0019] The present invention also discloses a method for using the integral die dropping device, which specifically comprises the following steps:

[0020] S1. In the initial state, the upper locking mechanism and the lower locking mechanism are both in an unlocked state. The steel strand is passed through the upper locking mechanism, the through-type jack, the lower locking mechanism, the continuous beam reserved hole and the bottom mold reserved hole from top to bottom, and then the bottom end of the steel strand is locked with an anchor.

[0021] S2, start the drive motor, after the drive motor is started, it drives the reciprocating screw to rotate, and when the reciprocating screw rotates, it drives the outer sleeve guided by the outer sleeve plate to continuously move rightward, and during the outer sleeve movement to the right, the first return spring and the inner sleeve drive the push plate to move rightward synchronously, and the outer sleeve drives the push block and the push column to move rightward synchronously;

[0022] S3, when the rightward movement distance of the outer sleeve reaches the first threshold, the push plate fits with the moving roller in the upper locking mechanism, and as the push plate continues to move rightward, the mounting seat in the upper locking mechanism compresses the adjacent second return spring, and at the same time drives the locking block to move rightward inside the locking seat through the adjacent sliding column;

[0023] S4, when the rightward movement distance of the outer sleeve reaches the second threshold, the locking block in the upper locking mechanism cooperates with the adjacent locking seat to complete the locking of the upper section of the steel strand, at this time, the connection between the bottom mold and the side mold is released and the through-type jack is started, and the through-type jack drives its output shaft to descend and retract, and during the descending process of the through-type jack output shaft, the bottom mold is driven to descend synchronously through the steel strand;

[0024] S5. Due to the obstruction of the moving roller in the upper locking mechanism, the push plate cannot continue to move rightward. As the outer sleeve continues to move rightward, the first return spring is compressed by the inner sleeve which also cannot move rightward. At the same time, the outer sleeve continues to drive the push block and the push column to move rightward.

[0025] S6, when the rightward movement distance of the outer sleeve reaches the third threshold, the inclined surface of the end of the push column fits with the inclined surface on the inner side of the entrance of the trigger groove. As the push column continues to move rightward, the push column pushes the trigger block through the inclined surface, so that the trigger block stretches the third reset spring and drives the limit column to move upward, so that the limit column moves out from the inner side of the adjacent triangular limit groove;

[0026] S7, when the rightward movement distance of the outer sleeve reaches the fourth threshold, the right end of the push block is in contact with the moving roller in the lower locking mechanism, and as the push block continues to move rightward, the mounting seat in the lower locking mechanism compresses the adjacent second return spring, and at the same time drives the locking block to move rightward inside the locking seat through the adjacent sliding column;

[0027] S8, when the rightward movement distance of the outer sleeve reaches the fifth threshold, the end of the push post contacts the inclined surface on the left side of the guide block, and as the guide block continues to move rightward, the inclined surface on the left side of the guide block guides the push post, so that the push post gradually rotates inside the U-shaped frame, and the push post gradually moves out from the inside of the trigger groove;

[0028] S9, when the rightward movement distance of the outer sleeve reaches the sixth threshold, the locking block in the lower locking mechanism cooperates with the adjacent locking seat to complete the locking of the lower segment of the steel strand, and at the same time, the push column moves out from the inner side of the trigger groove. At this time, the stretched third reset spring drives the trigger block to move downward and reset, and then the bottom end of the limit column is inserted into the inner side of the adjacent triangular limit groove to lock the sliding column in the lower locking mechanism to maintain the locking state of the lower segment of the steel strand. At this time, the outer sleeve is located at the rightmost end of the reciprocating thread outside the reciprocating screw. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves left and resets.

[0029] S10, when the outer sleeve moves to the left by a distance reaching the seventh threshold, the compressed first return spring is reset, and the push plate no longer presses the moving roller in the upper locking mechanism, and the locking state of the upper section of the steel strand is released, so that the through-type jack drives its output shaft to rise;

[0030] S11. When the left movement distance of the outer sleeve reaches the eighth threshold, the outer sleeve arrives at the initial position. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves right again to complete the above operation again. When the push column drives the trigger block to move upward again, the trigger block drives the limit column to release the lock of the sliding column in the lower locking mechanism. At this time, the compressed second reset spring in the lower locking mechanism drives the sliding column and the locking block in the lower locking mechanism to reset through the adjacent mounting seat.

[0031] Technical effects and advantages of the present invention:

[0032] The present invention is provided with a first driving mechanism, a second driving mechanism, a through-type jack, an upper locking mechanism, a lower locking mechanism and a limiting mechanism, so that the first driving mechanism can be used to drive the second driving mechanism to move right synchronously. During the rightward movement of the first driving mechanism, the upper locking mechanism is driven, and then the upper locking mechanism locks the upper part of the steel strand, so that the through-type jack can drive the steel strand to descend through the upper locking mechanism, and then the bottom mold is lowered, and then the first driving mechanism continues to drive the second driving mechanism to move right, so that the second driving mechanism drives the limiting mechanism and the lower locking mechanism in turn, firstly releasing the limiting mechanism on the lower locking mechanism, and then the lower locking mechanism locks the lower part of the steel strand, so that the subsequent through-type jack can drive the upper locking mechanism to move up and reset, and then the bottom mold drop operation is completed after repeating the above operation for many times. Compared with the same type of devices and methods in the prior art, the present invention has a higher degree of automation, does not require frequent repeated opening and closing operations by humans, saves manpower, and can effectively increase the lowering frequency, thereby improving the landing efficiency of the bottom mold.

[0044] By setting the above structure, the drive motor 22 can drive the reciprocating screw 21 to rotate after it is started. When the reciprocating screw 21 rotates, it drives the outer sleeve 23 guided by the outer sleeve plate 31 to continuously move right.

[0046] By setting the above structure, the outer sleeve 23 can be driven by the outer sleeve plate 31 to synchronously move the push block 32 and the push column 34 to the right during the rightward movement.

[0047] like Figure 4 As shown, the upper locking mechanism 5 and the lower locking mechanism 6 both include a locking seat 61, a locking block 62, a sliding column 63, a mounting seat 64, a second return spring 65 and a moving roller 66, wherein the locking seat 61 in the upper locking mechanism 5 is fixedly arranged at the top end of the output shaft of the through-type jack 4, and the locking seat 61 in the lower locking mechanism 6 is fixedly arranged at the bottom of the inner cavity of the shell 1, the locking block 62 is slidably arranged on the inner side of the locking seat 61 along the horizontal direction, the sliding column 63 is slidably penetrated and arranged on the left side of the locking seat 61 and is fixedly connected to the locking block 62, the mounting seat 64 is fixedly arranged at the left end of the sliding column 63, the second return spring 65 is sleeved on the outer side of the sliding column 63 and is fixedly connected between the locking seat 61 and the mounting seat 64, and two moving rollers 66 are provided, and the two moving rollers 66 are rotatably nested in the inner side of the mounting seat 64 through bearings along the vertical direction.

[0048] By setting the above structure, after the push plate 26 is fitted with the moving roller 66 in the upper locking mechanism 5, as the push plate 26 continues to move rightward, the mounting seat 64 in the upper locking mechanism 5 compresses the adjacent second return spring 65, and at the same time drives the locking block 62 to move rightward inside the locking seat 61 through the adjacent sliding column 63, until the locking block 62 in the upper locking mechanism 5 cooperates with the adjacent locking seat 61 to complete the locking of the upper section of the steel strand;

[0049] When the right end of the push block 32 is in contact with the movable roller 66 in the lower locking mechanism 6, as the push block 32 continues to move right, the mounting seat 64 in the lower locking mechanism 6 compresses the adjacent second return spring 65, and at the same time drives the locking block 62 to move right inside the locking seat 61 through the adjacent sliding column 63, until the locking block 62 in the lower locking mechanism 6 cooperates with the adjacent locking seat 61 to complete the locking of the lower segment of the steel strand.

[0050] like Figure 5 As shown, the limiting mechanism 7 includes a triangular limiting groove 71, a limiting column 72, a trigger block 73, a trigger groove 74, a third return spring 75 and a guide block 76, wherein the triangular limiting groove 71 is provided in plurality, and the plurality of triangular limiting grooves 71 are evenly arranged at the top of adjacent sliding columns 63, the limiting column 72 is slidably penetrated and arranged at the top of the adjacent locking seat 61, the trigger block 73 is fixedly arranged at the top of the limiting column 72, the trigger groove 74 is arranged at the front of the trigger block 73, and an inclined surface is arranged on the inner side of the left end of the trigger groove 74, the third return spring 75 is sleeved and arranged on the outer side of the limiting column 72 and fixedly connected between the triangular limiting groove 71 and the trigger block 73, and the guide block 76 is fixedly arranged at the top of the adjacent triangular limiting groove 71.

[0051] By setting the above structure, after the inclined surface at the end of the push column 34 fits with the inclined surface on the inner side of the entrance of the trigger groove 74, as the push column 34 continues to move right, the push column 34 pushes the trigger block 73 through the inclined surface, so that the trigger block 73 stretches the third return spring 75, and at the same time drives the limit column 72 to move upward, so that the limit column 72 moves out from the inner side of the adjacent triangular limit groove 71, thereby releasing the limit on the sliding column 63 in the lower locking mechanism 6, so that if the lower locking mechanism 6 locks the lower section of the steel strand at this time, the lower locking mechanism 6 releases the locking operation;

[0053] Example 2

[0054] The present invention also discloses a method for using the integral die dropping device, which specifically comprises the following steps:

[0055] S1. In the initial state, the upper locking mechanism 5 and the lower locking mechanism 6 are both in an unlocked state. The steel strand is passed through the upper locking mechanism 5, the through-type jack 4, the lower locking mechanism 6, the continuous beam reserved hole and the bottom mold reserved hole from top to bottom, and then the bottom end of the steel strand is locked with an anchor;

[0056] S2, start the drive motor 22, and after the drive motor 22 is started, it drives the reciprocating screw 21 to rotate. When the reciprocating screw 21 rotates, it drives the outer sleeve 23 guided by the outer sleeve 31 to continuously move rightward. During the rightward movement of the outer sleeve 23, the first return spring 24 and the inner sleeve 25 drive the push plate 26 to move rightward synchronously, and the outer sleeve 31 drives the push block 32 and the push column 34 to move rightward synchronously;

[0057] S3, when the rightward movement distance of the outer sleeve 23 reaches the first threshold, the push plate 26 is in contact with the moving roller 66 in the upper locking mechanism 5, and as the push plate 26 continues to move rightward, the mounting seat 64 in the upper locking mechanism 5 compresses the adjacent second return spring 65, and at the same time drives the locking block 62 to move rightward inside the locking seat 61 through the adjacent sliding column 63;

[0058] S4, when the rightward movement distance of the outer sleeve 23 reaches the second threshold, the locking block 62 in the upper locking mechanism 5 cooperates with the adjacent locking seat 61 to complete the locking of the upper section of the steel strand. At this time, the connection between the bottom mold and the side mold is released and the through-type jack 4 is started. The through-type jack 4 drives its output shaft to descend and retract. During the descending process of the output shaft of the through-type jack 4, the bottom mold is driven to descend synchronously through the steel strand.

[0059] S5. Due to the obstruction of the moving roller 66 in the upper locking mechanism 5, the push plate 26 cannot continue to move rightward. Subsequently, as the outer sleeve 23 continues to move rightward, the first return spring 24 is compressed by the inner sleeve 25 which also cannot move rightward. At the same time, the outer sleeve 31 continues to drive the push block 32 and the push column 34 to move rightward.

[0060] S6, when the rightward movement distance of the outer sleeve 23 reaches the third threshold, the inclined surface of the end of the push column 34 fits with the inclined surface on the inner side of the entrance of the trigger groove 74. Subsequently, as the push column 34 continues to move rightward, the push column 34 pushes the trigger block 73 through the inclined surface, so that the trigger block 73 stretches the third return spring 75, and at the same time drives the limit column 72 to move upward, so that the limit column 72 moves out from the inner side of the adjacent triangular limit groove 71;

[0061] S7, when the rightward movement distance of the outer sleeve 23 reaches the fourth threshold, the right end of the push block 32 is in contact with the moving roller 66 in the lower locking mechanism 6, and as the push block 32 continues to move rightward, the mounting seat 64 in the lower locking mechanism 6 compresses the adjacent second return spring 65, and at the same time drives the locking block 62 to move rightward on the inner side of the locking seat 61 through the adjacent sliding column 63;

[0062] S8, when the rightward movement distance of the outer sleeve 23 reaches the fifth threshold, the end of the push post 34 contacts the inclined surface on the left side of the guide block 76, and as the guide block 76 continues to move rightward, the inclined surface on the left side of the guide block 76 guides the push post 34, so that the push post 34 gradually rotates inside the U-shaped frame 33, and then the push post 34 gradually moves out from the inside of the trigger slot 74;

[0063] S9, when the rightward movement distance of the outer sleeve 23 reaches the sixth threshold, the locking block 62 in the lower locking mechanism 6 cooperates with the adjacent locking seat 61 to complete the locking of the lower segment of the steel strand, and at the same time, the push column 34 moves out from the inner side of the trigger groove 74. At this time, the stretched third reset spring 75 drives the trigger block 73 to move down and reset, and then the bottom end of the limit column 72 is inserted into the inner side of the adjacent triangular limit groove 71 to lock the sliding column 63 in the lower locking mechanism 6 to maintain the locked state of the lower segment of the steel strand. At this time, the outer sleeve 23 is located at the rightmost end of the reciprocating thread on the outer side of the reciprocating screw 21. Subsequently, as the reciprocating screw 21 continues to rotate, the outer sleeve 23 moves left and resets.

[0064] S10, when the outer sleeve 23 moves to the left by a distance reaching the seventh threshold, the compressed first return spring 24 is reset, and the push plate 26 no longer presses the moving roller 66 in the upper locking mechanism 5, and the locking state of the upper section of the steel strand is released, so that the through-type jack 4 drives its output shaft to rise;

[0065] S11, when the left movement distance of the outer sleeve 23 reaches the eighth threshold, the outer sleeve 23 arrives at the initial position, and then as the reciprocating screw 21 continues to rotate, the outer sleeve 23 moves right again to complete the above operation again, and when the push column 34 drives the trigger block 73 to move upward again, the trigger block 73 drives the limit column 72 to release the lock of the sliding column 63 in the lower locking mechanism 6. At this time, the compressed second reset spring 65 in the lower locking mechanism 6 drives the sliding column 63 and the locking block 62 in the lower locking mechanism 6 to reset through the adjacent mounting seat 64.

[0066] It should also be noted that, during the subsequent operation, the operator can drive the output shaft of the through-type jack 4 to descend or ascend according to the actual working conditions.

[0067] Example 3

[0068] It should also be noted that the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold and the sixth threshold increase in sequence, and the seventh threshold and the eighth threshold increase in sequence. At the same time, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold and the eighth threshold are recorded for the convenience of accurately describing the actual working conditions of the scheme;

[0069] When the solution of the present application is actually produced, according to the actual specifications of the reciprocating screw 21, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold and the eighth threshold are all specific values.

[0070] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

7. The integral die dropping device according to claim 6, characterized in that: Also included is a method for using the integral die dropping device, the method specifically comprising the following steps: S1. In the initial state, the upper locking mechanism (5) and the lower locking mechanism (6) are both in an unlocked state, and the steel strand is passed through the upper locking mechanism (5), the through-type jack (4), the lower locking mechanism (6), the continuous beam reserved hole and the bottom mold reserved hole from top to bottom, and then the bottom end of the steel strand is locked using an anchor; S2, start the driving motor (22), after which the driving motor (22) drives the reciprocating screw (21) to rotate, and when the reciprocating screw (21) rotates, the outer sleeve (23) guided by the outer sleeve (31) is driven to continuously move rightward, and during the rightward movement of the outer sleeve (23), the push plate (26) is driven to move rightward synchronously through the first return spring (24) and the inner sleeve (25), and the push block (32) and the push column (34) are driven to move rightward synchronously through the outer sleeve (31); S3, when the rightward movement distance of the outer sleeve (23) reaches a first threshold value, the push plate (26) is in contact with the moving roller (66) in the upper locking mechanism (5), and as the push plate (26) continues to move rightward, the mounting seat (64) in the upper locking mechanism (5) compresses the adjacent second return spring (65), and at the same time drives the locking block (62) to move rightward on the inner side of the locking seat (61) through the adjacent sliding column (63); S4, when the rightward movement distance of the outer sleeve (23) reaches the second threshold value, the locking block (62) in the upper locking mechanism (5) cooperates with the adjacent locking seat (61) to complete the locking of the upper section of the steel strand. At this time, the connection between the bottom mold and the side mold is released and the through-type jack (4) is started. The through-type jack (4) drives its output shaft to descend and retract. During the descending process of the output shaft of the through-type jack (4), the bottom mold is driven to descend synchronously through the steel strand. S5. Due to the obstruction of the moving roller (66) in the upper locking mechanism (5), the push plate (26) cannot continue to move rightward. Subsequently, as the outer sleeve (23) continues to move rightward, the first return spring (24) is compressed by the inner sleeve (25) which is also unable to move rightward. At the same time, the outer sleeve (31) continues to drive the push block (32) and the push column (34) to move rightward. S6, when the rightward movement distance of the outer sleeve (23) reaches the third threshold value, the inclined surface at the end of the push column (34) fits with the inclined surface on the inner side of the entrance of the trigger groove (74), and as the push column (34) continues to move rightward, the push column (34) pushes the trigger block (73) through the inclined surface, thereby causing the trigger block (73) to stretch the third return spring (75), and at the same time drives the limit column (72) to move upward, so that the limit column (72) moves out from the inner side of the adjacent triangular limit groove (71); S7, when the rightward movement distance of the outer sleeve (23) reaches the fourth threshold value, the right end of the push block (32) is in contact with the moving roller (66) in the lower locking mechanism (6), and as the push block (32) continues to move rightward, the mounting seat (64) in the lower locking mechanism (6) compresses the adjacent second return spring (65), and at the same time drives the locking block (62) to move rightward on the inner side of the locking seat (61) through the adjacent sliding column (63); S8, when the rightward movement distance of the outer sleeve (23) reaches the fifth threshold value, the end of the push column (34) contacts the inclined surface on the left side of the guide block (76), and as the guide block (76) continues to move rightward, the inclined surface on the left side of the guide block (76) guides the push column (34), so that the push column (34) gradually rotates inside the U-shaped frame (33), and the push column (34) gradually moves out from the inside of the trigger slot (74); S9, when the rightward movement distance of the outer sleeve (23) reaches the sixth threshold value, the locking block (62) in the lower locking mechanism (6) cooperates with the adjacent locking seat (61) to complete the locking of the lower section of the steel strand, and at the same time, the push column (34) moves out from the inner side of the trigger groove (74). At this time, the stretched third reset spring (75) drives the trigger block (73) to move downward and reset, thereby causing the bottom end of the limit column (72) to be inserted into the inner side of the adjacent triangular limit groove (71) to lock the sliding column (63) in the lower locking mechanism (6) to maintain the locked state of the lower section of the steel strand. At this time, the outer sleeve (23) is located at the rightmost end of the reciprocating thread on the outer side of the reciprocating screw (21). Subsequently, as the reciprocating screw (21) continues to rotate, the outer sleeve (23) moves leftward and resets. S10, when the distance of the outer sleeve (23) moving to the left reaches the seventh threshold, the compressed first return spring (24) is reset, and at the same time, the push plate (26) no longer presses the moving roller (66) in the upper locking mechanism (5), and the locking state of the upper section of the steel strand is released, so that the through-type jack (4) drives its output shaft to rise; S11, when the leftward movement distance of the outer sleeve (23) reaches the eighth threshold value, the outer sleeve (23) arrives at the initial position, and subsequently, as the reciprocating screw (21) continues to rotate, the outer sleeve (23) moves rightward again to complete the above operation again, and when the push column (34) drives the trigger block (73) to move upward again, the trigger block (73) drives the limit column (72) to release the lock of the sliding column (63) in the lower locking mechanism (6), and at this time, the compressed second reset spring (65) in the lower locking mechanism (6) drives the sliding column (63) and the locking block (62) in the lower locking mechanism (6) to reset through the adjacent mounting seat (64).
