Description

Technical Field

[0001] The present invention relates to the technical field of safety protection, in particular to a telescopic anti-collision device for a movable die table. Background Art

[0002] In the production process of prefabricated parts, the use of mobile formwork is an indispensable part of the production process. The formwork serves as the base for the production of prefabricated components. All processes involved in the production of prefabricated components, such as steel bar binding, side formwork installation, embedded pipe installation, and concrete pouring, need to be completed on the formwork. In order to improve production efficiency, in actual production, the production of standard components such as prefabricated composite panels and prefabricated exterior wall panels is carried out in an assembly line construction manner.

[0003] During the construction process, the steel mobile formwork is placed on the walking wheels, where rails are provided on the ground for limiting the movement of the walking wheels. A formwork driving device is also provided on the ground for moving the formwork to various workstations.

[0004] In order to prevent collisions between mold tables during movement, which causes inelastic deformation of the side walls of the mold tables, and to prevent accidental squeezing of operators and mechanical injury accidents when the mold tables collide with each other, two anti-collision blocks are usually installed at both ends of the mold table during operation. The anti-collision blocks are made of rubber and are rigidly connected to the ends of the mold tables through detachable bolts.

[0005] In the prefabricated parts production process, the last step is to place the prefabricated components into an automatic curing kiln for curing, that is, using steam to achieve curing. Because the size of the automatic curing kiln usually matches that of the mobile formwork, but does not take into account the problem of the formwork becoming larger in size after the anti-collision block is installed, resulting in the formwork equipped with the anti-collision block entering the automatic curing kiln. The automatic closing door of the curing kiln cannot be closed normally, thus failing to achieve the purpose of closed protection and curing.

[0006] Therefore, in the actual production process, operators usually remove the anti-collision blocks before the mold table enters the curing kiln, or do not install anti-collision blocks on the mold table during the production process. The first method seriously affects the service life of the anti-collision blocks because the mold table anti-collision blocks are repeatedly disassembled and assembled, and the anti-collision blocks and the mold table are rigidly connected with bolts, and the safety risks in the operation process are greatly increased during the disassembly and assembly of the anti-collision blocks; the second method is that during use, collisions may occur between the mold tables, resulting in inelastic deformation, affecting the service life of the mold table, or there is a possibility of injury to the staff.

The automatic closing door of the curing kiln cannot be closed normally, thereby failing to achieve the purpose of closed protection and curing.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. First of all, this application adopts anti-collision glue that can move longitudinally. The anti-collision glue is used to avoid the non-elastic shape that may be produced when the mold tables collide with each other, and can avoid the squeezing of the operators caused by the collision of the mold tables, avoid the occurrence of mechanical injury accidents, and ensure safe production.

DETAILED DESCRIPTION

[0030] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figure 1-7 As shown, a retractable anti-collision device for a movable mold platform includes an anti-collision mechanism 1, a frame structure 2 and a locking mechanism 3. First, the anti-collision mechanism 1 is used in this application to realize the deformation that may occur when the mold platforms contact each other, wherein the anti-collision mechanism 1 is slidably set on the frame structure 2, and a locking mechanism 3 is provided at the bottom of the anti-collision mechanism 1, so that under the action of the locking mechanism 3, the anti-collision part of the anti-collision mechanism 1 can be retracted before the mold platform is put into the curing kiln to ensure the overall size of the mold platform, so that the automatic closing door of the curing kiln can be closed normally, and the curing kiln can be used to cure the prefabricated components.

[0032] Specifically, the present application utilizes the locking mechanism 3 and the frame structure 2 to retract the anti-collision mechanism 1, so that the protruding part of the anti-collision mechanism 1 can be retracted when the device enters the curing kiln, thereby ensuring that the curing kiln can achieve the curing function and ensure the service life of the prefabricated components.

[0033] First, in this application, the anti-collision mechanism 1 includes an anti-collision rubber 11 and a sliding rod 12, wherein the anti-collision rubber 11 is arranged at the end of the sliding rod 12, wherein the sliding rod 12 and the frame structure 2 are slidingly connected, and the sliding rod 12 is arranged at the end of the locking mechanism 3. During specific use, the anti-collision rubber 11 is used to realize the anti-collision function of the entire device, and the sliding connection between the sliding rod 12 and the frame structure 2 is used to realize the retraction of the anti-collision rubber 11, so that the end of the anti-collision rubber 11 is directly retracted when in the curing kiln, avoiding the mold platform affecting the closing of the automatic closing door of the curing kiln.

[0034] The frame structure 2 includes a first frame 21, a second frame 22, and a third frame 23. The first frame 21 and the third frame 23 are symmetrically arranged on both sides of the second frame 22. The second frame 22 is provided with two groups to form a "mouth"-shaped frame, which can facilitate the placement of the locking mechanism 3 inside the frame structure 2. The first frame 21 and the sliding rod 12 are slidably connected, so that the sliding rod 12 can slide longitudinally.

[0035] Furthermore, the locking mechanism 3 includes a connecting slider 31, a telescopic spring 37 and a guide locking component. First, a connecting slider 31 is fixed to the end of the sliding rod 12, and the connecting slider 31 and the second frame 22 are slidingly connected, that is, a first slider 33 is fixed on the side of the connecting slider 31, and a first sliding groove 32 is opened on the side of the second frame 22, wherein the first slider 33 and the first sliding groove 32 are slidingly connected to realize the longitudinal sliding of the connecting slider 31, a telescopic spring 37 is fixed between the connecting slider 31 and the third frame 23, and a guide locking component is also provided on the third frame 23 and the connecting slider 31 for realizing the limitation of the position of the connecting slider 31. In this application, the telescopic spring 37 is used to provide an upward force to the connecting slider 31.

[0036] Specifically, when the anti-collision rubber 11 is pressed down, the sliding rod 12 slides downward, driving the connecting slider 31 to slide downward, so that the telescopic spring 37 is squeezed. When it is squeezed to a certain position, it can be guided and fixed by the guiding locking component. At this time, the anti-collision rubber 11 is in a retracted position, so that the mold platform will not affect the closing of the automatic closing door of the curing kiln, thereby ensuring the curing function of the curing kiln.

[0037] The guide locking component includes a pulley 34. First, a hexagonal cavity is defined in the center of the connecting slider 31. A second slot 313 is defined on the connecting slider 31 within the hexagonal cavity. A mounting block 311 is fixed to the side of the hexagonal cavity. An internal guide block 310 is fixed to the end of the mounting block 311. The structure of the internal guide block 310 matches the shape of the hexagonal cavity, but the size of the internal guide block 310 is smaller than the hexagonal cavity. A third slot 312 is defined on the side of the internal guide block 310. The positions of the second slot 313 and the third slot 312 correspond to each other, thereby enabling the movement of the pulley 34. The pulley 34 is rotatably mounted on a first rotating shaft 38, which is fixed to a straight arm 35. A movable sleeve 39 is fixed to the end of the straight arm 35, and the movable sleeve 39 is rotatably mounted on a movable base 36. In the present application, the straight arm rod 35 drives the pulley 34 to slide back and forth inside the second slide groove 313 and the third slide groove 312. During the sliding process, the inclination angle of the straight arm rod 35 changes adaptively. A locking groove is provided at the top of the third slide groove 312 for limiting the locking position of the pulley 34. The specific situation is as follows.

[0038] First, the second chute 313 includes six inflection points, which are defined as A2, B2, C2, D2, E2, and F2, respectively. The pulley 34 passes through D2, E2, A2, B2, C2, F2, and D2 in sequence to achieve a cycle. The third chute 312 is correspondingly provided with six inflection points, which are defined as A1, B1, C1, D1, E1, and F1, respectively. The pulley 34 passes through D1, E1, A1, B1, C1, F1, and D1 in sequence to achieve a cycle. D1 and D2 are the lowest ends, and the inflection points of D1 and D2 are in an arc angle. When the support force of the telescopic spring 37 and the gravity of the connecting slider 31 are offset, the pulley 34 is at the D2 position. At this time, the pulley 34 is not subject to force. When the connecting slider 31 moves downward under the action of an external force, the straight arm 35 will rotate. At this time, the pulley 34 will move toward E2 along the direction of D2 and E2, wherein the inflection point of E2 and E1 is also in an arc angle. At this time, the pulley 34 passes through E2 and E1 and moves to the connecting slider. As the block 31 continues to move downward, the pulley 34 moves toward A1 and A2, and the external force is released when it reaches A1 and A2, wherein the height of B1 is lower than the height of A1, and the height of B2 is lower than the height of A2. Under the supporting force of the telescopic spring 37, the connecting slider 31 moves upward, and the pulley 34 reaches B1 and B2 points, wherein B1 and B2 are straight inflection points, and there is a locking groove at the B1 position. The pulley 34 is now located inside the locking groove, realizing the locking action of the connecting slider 31. At this time, the sliding rod 12 is in a locked state. To unlock the locked state, you need to press the sliding rod 12 again to move the connecting slider 31 downward. The pulley 34 will follow the path from B1 to C1 and reach the C1 position, where the corners of C1 and C2 are arc angles, and the height of C1 is higher than the height of B1, and the height of C2 is higher than the height of B2. At this time, release the pulley 34, and the pulley 34 will follow the path of C1 and F1 to reach the original position D2, thereby unlocking the sliding rod 12.

[0039] Specifically, to prevent the straight arm 35 and the pulley 34 from getting stuck, an anti-jamming mechanism 4 is provided in the present application. The anti-jamming mechanism 4 includes a telescopic rod 42. First, a sliding sleeve 45 is slidably provided on the straight arm 35. A second rotating shaft 44 is fixed to the side of the sliding sleeve 45. The second rotating shaft 44 is rotatably connected to a first base 43. The first base 43 is fixed to the movable end of the telescopic rod 42. The telescopic rod 42 is fixed to a telescopic mounting base 41, and the telescopic mounting base 41 is fixed to the second frame 22. When a jam is likely to occur, the telescopic rod 42 is used to enable the sliding sleeve 45 to slide on the straight arm 35, thereby adjusting the rotation angle of the straight arm 35 and ensuring that the pulley 34 slides normally within the second and third chute 313 and 312.

[0040] When the present invention is in use, firstly, the present application adopts an anti-collision rubber 11 that can move longitudinally, and uses the anti-collision rubber 11 to avoid the non-elastic shape that may be generated when the mold tables collide with each other, and can avoid the squeezing of the operators caused by the collision of the mold tables, avoid the occurrence of mechanical injury accidents, and ensure safe production. At the same time, in the present application, the shrinkable anti-collision rubber 11 is used, so that in the last step of production, the mold table can enter the curing kiln for curing. The raised part of the mold table is contracted, so that the mold table can directly enter the interior of the curing kiln without affecting the closing of the automatic closing door in the curing kiln, thereby ensuring the function of sealing protection and curing;

[0041] In order to realize the contraction of the raised portion of the die table, in this application, a locking mechanism 3 is used to realize the above function. Therefore, in this application, the third slide 312 and the second slide 313 are used to realize the contraction. In this application, there are six inflection points. The second slide 313 includes six inflection points, which are defined as A2, B2, C2, D2, E2, and F2 respectively. The pulley 34 passes through D2, E2, A2, B2, C2, F2, and D2 in sequence to realize a cycle. There are six inflection points corresponding to the groove 312, which are defined as A1, B1, C1, D1, E1, and F1 respectively. The pulley 34 passes through D1, E1, A1, B1, C1, F1, and D1 in sequence to achieve a cycle. When the support force of the telescopic spring 37 and the gravity of the connecting slider 31 are offset, the pulley 34 is at the D2 position. At this time, the pulley 34 is not under force. When the connecting slider 31 moves downward under the action of external force, the straight arm 35 will rotate, and the pulley 34 will move along D2 and In the direction of E2, it moves toward E2, where the inflection point of E2 and E1 is also an arc angle. At this time, the pulley 34 passes E2 and E1. When the connecting slider 31 continues to move downward, the pulley 34 moves toward A1 and A2. When it reaches A1 and A2, the external force is released. Under the support force of the telescopic spring 37, the connecting slider 31 moves upward. At this time, the pulley 34 reaches B1 and B2 points, where B1 and B2 are straight inflection points, and there is a locking groove at the B1 position. The pulley 34 is now located inside the locking groove. , realizing the locking effect on the connecting slider 31. At this time, the sliding rod 12 is in the locked state. To unlock the locked state, it is necessary to press the sliding rod 12 again to move the connecting slider 31 downward. The pulley 34 will follow the path from B1 to C1 and reach the C1 position, where the corner of C1 and C2 is an arc angle. At this time, release the pulley 34, and the pulley 34 will follow the path of C1 and F1 to reach the original position D2, realizing the unlocking of the sliding rod 12, thereby realizing the locking and opening of the connecting slider 31;

[0042] In the present application, in order to avoid the straight arm rod 35 and the pulley 34 from getting stuck, an anti-stuck mechanism 4 is also provided in the present application. The specific working process is that when the straight arm rod 35 and the pulley 34 get stuck, the telescopic rod 42 is extended or shortened to adjust the rotation angle of the straight arm rod 35, so that the straight arm rod 35 rotates on the movable base 36, ensuring that the pulley 34 slides normally inside the second slide groove 313 and the third slide groove 312. When there is no jam, the telescopic rod 42 is in a stress-free state. When the straight arm rod 35 rotates around the movable base 36, the second rotating shaft 44 rotates freely on the first base 43, and the sliding sleeve 45 slides adaptively on the straight arm rod 35. The telescopic rod 42 can be a cylinder, an electric telescopic rod, a hydraulic rod, etc.
