Description

Technical Field

[0001] The invention relates to the technical field of block transfer, in particular to a clamping device for transfer of prefabricated blocks. Background Art

[0002] A block is a block-shaped building product that is larger than a clay brick. Common block materials include concrete, cement mortar, aerated concrete, and fly ash silicate. Blocks are roughly divided into two parts according to different usage environments: dense blocks and hollow blocks. Blocks are widely used in the construction field and can be used as load-bearing walls and partition walls. Dense or hollow blocks can meet these needs. After the blocks are produced in the factory, they need to be transported to an open area for easy transportation.

[0003] Traditional gantry cranes use a driving structure and a clamping structure in combination, and lack an independent control unit. As a result, under complex working conditions, the movement of the clamping assembly is difficult to adjust precisely, and only synchronous clamping movements can be achieved. It is impossible to perform asynchronous clamping adjustments based on the shape, size or processing requirements of the workpiece, which limits the applicability of the clamping device in a variety of application scenarios. In particular, when precise control of the clamping force and position is required, it is difficult to meet production requirements.

[0038] By adopting the above technical scheme, the first electric push rod 91 and the second electric push rod 101 accurately adjust the positions of the telescopic adjustment rod 93 and the auxiliary adjustment rod 103, so that the first clamping seat 96 and the second clamping seat 106 are accurately clamped in the first clamping slot 68, the third clamping slot 85 and the second clamping slot 77. The adjustment structure enables the reversing component to be flexibly adjusted according to different working conditions and needs, and the rotation angle of the rotating rod 72 or the extension rod 631 can be changed, as well as the clamping position of the clamping frame 58 can be adjusted, thereby improving the adaptability and flexibility of the device; the first articulated seat 94, the fixed seat 95, the second articulated seat 102 and the auxiliary seat 104 and other components are hingedly connected, and the telescopic adjustment rod 93 and the auxiliary adjustment rod 103 are rotatably connected, which enhances the stability and reliability of the adjustment structure, and the reversing component is controlled to work through the adjustment structure, thereby achieving the purpose of individually controlling the operation of the transverse clamping structure, the longitudinal clamping structure and the rotating structure.

[0039] Working principle: The output end of the first motor 23 is connected to the reducer 24, and the output end of the reducer 24 is connected to the bevel gear 25, which cooperates with the linear toothed plate 12 to drive the upper frame 3 and the clamping assembly to move, wherein the climbing frame 35 is driven to rise or fall through the output end of the hydraulic push rod 34 to adjust the distance between the clamping assembly and the material; when the clamping assembly needs to be used, the second motor 6 drives the first bevel gear 62 and the second bevel gear 63 to rotate, and the extension rod 631 of the second bevel gear 63 drives the second bevel gear 63 and the fourth bevel gear 65 and the first lower chuck 66 to rotate, and in this process, the longitudinal surface The clamping structure is driven to work, and the first lower chuck 66 drives the driving rod 5 and the first worm 53 to work, wherein the first worm 53 is meshed and connected with the first turbine 52, driving the threaded rod 54 at the center of the first turbine 52 to rotate, and through the cooperation between the threaded rod 54 and the sliding plate 57, the sliding plate 57 drives the first auxiliary connecting rod 571 and the second auxiliary connecting rod 572 to move in an arc shape. Since the third auxiliary connecting rod 573 is connected to the fork frame 56, the two clamping frames 58 will expand to both sides. When approaching the building block, the two clamping frames 58 and the clamping plate 59 are reset by rotating the threaded rod 54 to achieve clamping of the building block; Supplement to the clamping process: Since there is self-locking between the first turbine 52 and the first worm 53, and between the threaded rod 54 and the sliding plate 57, when the transverse surface clamping structure is needed, the first electric push rod 91 drives the fixed seat 95 and the first hinged seat 94 to squeeze downward. Under the action of pressure, the telescopic adjustment rod 93 moves in an arc shape with the assistance of the arc adjustment seat 92, and the ends of the telescopic adjustment rod 93 are rotatably connected to the first clamping seat 96, so the two ends of the telescopic adjustment rod 93 will be in an up and down state. Due to the downward squeezing of the telescopic adjustment rod 93, one of the first clamping seats 96 will lift the first upper chuck 67 and the first lower chuck 66 to separate. At this time, the power of the second motor 6 will not be transmitted to the fourth bevel gear 65 below, and the fourth bevel gear 65 will not drive the third bevel gear 64 and the driving rod 5 to rotate, and the kinetic energy will be transmitted through the double synchronous wheel 69 and the second synchronous belt 87 and the second synchronous wheel 86 are transmitted to the auxiliary rod 8. At this time, another first clamping seat 96 is pressed down, so that the third upper chuck 84 and the third lower chuck 83 are re-engaged, so that the eighth bevel gear 82 and the seventh bevel gear 81 are meshed and transmitted, thereby driving the two-way worm 44 to rotate, and the two-way worm 44 drives the first sector tooth plate 441 to move in an arc, and drives the second sector tooth plate 45 and the first connecting rod 451 and the second connecting rod 452 to move in an arc through the central axis of the first sector tooth plate 441. Since the second sector tooth plate 45 and the third sector tooth plate 46 are meshed, when the second sector tooth plate 45 and the third sector tooth plate 46 rotate, the first connecting rod 451, the second connecting rod 452 and the third connecting rod 461 and the fourth connecting rod 462 will stretch the extrusion plate 47 to move to the side away from the side plate 43, so as to achieve the purpose of stretching and extruding the building block, and the building block is clamped in this way; For blocks of different sizes, rotation is required: during the clamping process, when the transverse clamping structure needs to clamp the longitudinal surface of the block, the clamping assembly needs to rotate to clamp the block. Similarly, the kinetic energy input is realized through the second motor 6. At this time, the kinetic energy of the clamping assembly needs to be completely disconnected. At this time, the first electric push rod 91 makes the telescopic adjustment rod 93 in a horizontal state through the first hinge seat 94 and the fixed seat 95, that is, the angle between the first electric push rod 91 and the telescopic adjustment rod 93 is 90°, and the first clamping seat 96 no longer applies any pressure to the first upper chuck 67 and the third upper chuck 84. Therefore, the first lower chuck 66, the first upper chuck 67 and the third upper chuck 84 and the third lower chuck 83 are no longer connected. Then the second electric push rod 101 The auxiliary seat 104 is driven to move downward, so that the auxiliary adjusting rod 103 moves in an arc shape under the action of the second hinged seat 102. The second clamping seat 106 will drive the second upper chuck 76 to move downward under the action of the auxiliary adjusting rod 103 and mesh with the second lower chuck 75. Therefore, the second motor 6 drives the first bevel gear 62 and the second bevel gear 63 to rotate, and drives the extension rod 631 and the double synchronous wheel 69, the first synchronous belt 691 and the first synchronous wheel 78 to rotate. At this time, the rotating rod 72 drives the sixth bevel gear 74 and the fifth bevel gear 73 to rotate, and the fifth bevel gear 73 drives the second worm 7 to rotate, and the second worm 7 drives the second turbine 71 to rotate. The rotation of the second turbine 71 will drive the top plate 4 and the clamping assembly below to rotate, thereby clamping blocks of different sizes.
