Abstract
Description
Technical Field
[0001] This utility model relates to the field of segment mold transfer vehicles, and specifically refers to a segment mold transfer vehicle used in multi-layer curing kilns. Background Technology
[0002] Tunnel boring machine (TBM) segments are the main assembly components in TBM construction. They form the innermost barrier of the tunnel, resisting soil pressure, groundwater pressure, and other special loads. TBM segments are the permanent lining structure of a shield tunnel, and their quality directly affects the overall quality and safety of the tunnel, influencing its waterproofing and durability.
[0003] Currently, steam curing is the most common method used in precast tunnel segment manufacturing. To meet project production needs, a large workshop is typically required to house a single-story steam curing kiln. For older workshops with significant limitations in width and length, the conventional layout of molds is insufficient to meet project production requirements, resulting in low production efficiency.
[0004] Existing technology 201721471540.3 discloses a subway tunnel segment production line using a multi-layer steam curing kiln. Although it can solve the above problems, both the inlet and outlet trolleys are lifted by a lifting mechanism. If the lifting mechanism malfunctions, there is a safety hazard that the mold trolley will fall. Utility Model Content

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] Appendix Figure 1-3The segment mold transfer vehicle for multi-layer curing kilns described in this utility model comprises a transfer vehicle body 1, multiple track pulleys 2 rotatably arranged at intervals on both sides of the length of the transfer vehicle body 1, a drive assembly 3 located in the middle of the transfer vehicle body 1 for driving two of the track pulleys 2 to rotate, a transfer track working line 4 set on the factory ground for sliding of the track pulleys 2, a groove 5 located in the middle of the transfer track working line 4 for moving the transfer vehicle body 1, and a lifting assembly 6 set on the transfer vehicle body 1 for lifting and lowering the segment mold; the lifting assembly 6 includes lifting components mounted on the top surface of the transfer vehicle body. The support platform 61, the slide rail 62 set on the top surface of the support platform 61, the support rod 631 assembly 63 with one end slidably set at both ends of the bottom surface of the support platform 61 and the other end penetrating the main body of the transfer vehicle and fitting against the bottom of the groove 5, and the adjustment assembly 64 set on the main body of the transfer vehicle 1 for adjusting the spacing of the support assembly; the support assembly is located on the main body of the transfer vehicle 1 and is slidably set on the main body of the transfer vehicle 1; the bottom sides of the groove 5 are respectively provided with ramps 7 for lifting the support rod 631 assembly 63 and gradually raising it; the support rod 631 assembly 63 includes the support rod 631 assembly 63 set at both ends of the bottom surface of the support platform 61 and located on the bottom of the transfer vehicle 5. The system comprises four support rods 631 on both sides of the length of the body 1, four sliders 632 respectively fitted onto the four support rods 631 on a section of the transfer vehicle body 1, multiple sliding grooves 633 correspondingly arranged on the transfer vehicle body 1 for sliding of the four sliders 632, and two dovetail grooves 634 arranged at both ends of the bottom surface of the support platform 61 for sliding of one end of the four support rods 631; the adjustment assembly 64 includes two hydraulic cylinders 641 respectively arranged at the middle of both ends of the transfer vehicle body 1 with their drive ends facing the two sliders 632 at the same end, and two mounting plates 642 respectively arranged on the drive ends of the two hydraulic cylinders 641. Four connecting plates 643 are respectively hinged at one end to four sliders 632 and at the other end to both ends of two mounting plates 642; the length of one of the two mounting plates 642 is greater than the length of the other; the drive assembly 3 includes a drive shaft 31 rotatably disposed in the middle of the transfer vehicle body 1 and passing through both ends of the transfer vehicle body 1 and connected to two track pulleys 2 respectively, a drive motor 32 disposed in the middle of the transfer vehicle body 1 and located directly above the drive shaft 31, a drive gear 33 disposed on the drive end of the drive motor 32, and a driven gear 34 disposed on the drive shaft 31 and meshing with the drive gear 33.
[0020] Furthermore, each of the four support rods 631 is equipped with a support pulley 8 at its bottom for easy movement.
[0021] In use: The segment mold moves to the support platform 61 of the transfer vehicle body 1 via the transfer track working line 4. Then, two hydraulic cylinders 641 are activated, and the driving ends of the two hydraulic cylinders 641 drive the two mounting plates 642 to move between the two sliders 632 respectively. Since the mounting plates 642 and the two sliders 632 are hinged together by a connecting plate 643, when the mounting plates 642 move, they drive one end of the connecting plate 643 to move. Thus, the other end of the connecting plate 643 moves the two sliders 632 towards both sides of the transfer vehicle body 1. The four sliders 632 then drive the four support rods 631 to move towards both sides of the transfer vehicle body 1 respectively. Since the lengths of the two mounting plates 642 are not the same, the distances that two of the four support rods 631 move are also not the same as the distances that the other two support rods 631 move. The slopes 7 on both sides of the groove 5 also correspond to the adjusted positions of the four support rods 631. After adjustment, the drive motor 32 is activated to drive the drive gear 33 to rotate. Then, the drive gear 33 drives the driven gear 3 4. Rotate, and then the driven gear 34 drives the drive shaft 31 to rotate. Then the drive shaft 31 drives the two track pulleys 2 to rotate. Then the two track pulleys drive the transfer car body 1 to move. Then the remaining track pulleys 2 also rotate. Then the transfer car body 1 drives the support platform 61 and support rods 631 to move. When the bottom of the four support rods 631 respectively contacts the corresponding slope 7, as the slope 7 gradually increases, the four support rods 631 also gradually move upward to lift the support platform 61. Then the support platform 61 lifts the segment mold. After the segment mold moves to the second layer position of the curing cellar, the slope 7 of the groove 5 becomes horizontal. Thus, no matter how the segment mold is moved afterward, it will always be in the second layer position of the curing cellar. And the four support rods 631 will not malfunction and cause the segment to fall like the lifting equipment. When it is not necessary to lift the segment mold to the second layer position of the curing cellar, it is only necessary to start the drive motor 32 to drive the transfer car body 1 to move. At this time, the support rods 631 are located between the two slopes 7 and will not contact the slope 7.
[0022] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
