Technical Field

[0001] The invention relates to the technical field of shield segment prefabrication, and in particular to a shield segment mould detachable cover plate casting device. Background Art

[0002] As is known, shield segments are the main assembly components of shield construction, mostly used for barrier protection of tunnel excavation. They are used as the innermost barrier of the tunnel and can bear loads such as soil pressure and groundwater pressure. Due to their large size, shield segments are generally prepared in a prefabricated manner. They are cast in a casting mold according to specified sizes and then transported to the construction site for installation. It can be seen that the preparation of shield segments is an important step in road construction.

[0003] In the prior art, when preparing concrete precast parts, the concrete precast parts are formed by overlapping steel skeletons and poured concrete. Generally, during the preparation, the steel skeleton needs to be assembled in the lower mold, and then the upper mold is installed on the lower mold by hoisting or the like. However, in the actual production process, especially in large-scale batch casting, it is difficult to achieve automated continuous casting. Some manufacturers set up a traditional system for each mold to drive the upper mold to close the mold and the movement of the lower mold. However, compared with the preparation of batch precast parts, the transmission system is particularly consumed, and each set of molds needs to be equipped with a transmission system. Obviously, the production cost is greatly increased. Therefore, how to achieve continuous and automated casting of precast parts at a low cost is an urgent problem that technicians in this field need to solve. Summary of the invention

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0050] See also Figure 1-14 , a shield segment mold detachable cover casting device, an upper mold 5 and a lower mold 4, a casting space is formed between the upper mold 5 and the lower mold 4, and a second conveying frame 3 is included, which is used to carry the upper mold 5, and the upper mold 5 can slide laterally along the second conveying frame 3;

[0051] The first conveying frame 1 is arranged outside the second conveying frame 3, and a bearing mechanism is arranged on the first conveying frame 1, and the bearing mechanism can slide along the first conveying frame 1;

[0052] The bearing mechanism is used to bear the upper mold 5. A locking member is also provided on the upper mold 5, and the bearing mechanism is connected to the upper mold 5 through the locking member.

[0053] The bearing mechanism includes a bearing rod 21, a cross column 22 is arranged on the bearing rod 21, a through slot 501 is opened on the upper mold 5, and when the cross column 22 is inserted into the through slot 501 and moves to a set position, it is locked with the locking member;

[0054] When the upper mold 5 and the lower mold 4 are clamped together by the locking member, the locking member is passively unlocked from the upper mold 5 .

[0055] Specifically, the present application can carry the upper mold 5 on the second carrying frame and slide it to the top of the lower mold 4 through the cooperation of the supporting mechanism and the locking component, and then drive the supporting mechanism to move the upper mold 5 downward and close the film with the lower mold 4, and then in the process of closing the mold, passively unlock the upper mold 5 and the locking component. A conveying wheel 51 is provided under the upper mold, and then a conveying groove 301 is provided on the second conveying frame 3, which is used to carry the conveying wheel 51. The present application can not only passively lock the upper mold 5 through the provided locking component, not only can it provide stability between the supporting mechanism and the upper mold 5, but also can passively drive the locking component to unlock during closing the mold, which not only reduces the unlocking cost, but also can greatly shorten the unlocking time, facilitates the supporting mechanism to carry the next mold and the closing step, and improves the production efficiency of the shield segment as a whole.

[0056] Furthermore, the bearing mechanism further includes a sliding rod 2 which is slidably arranged on the first conveying frame 1 and is located above the second conveying frame 3, and a bearing rod 21 is arranged on a telescopic end below the sliding rod 2. Specifically, the sliding rod 2 is a telescopic rod or a hydraulic rod in the prior art, which can drive the bearing rod 21 to move up and down as needed.

[0057] Furthermore, the locking component includes a slider 7 slidably set on the upper mold 5, and a locking bevel block 71 is set on one side of the slider 7. A supporting block 52 is provided on one side of the upper mold 5. A supporting groove 5201 is opened on the supporting block 52. The locking bevel block 71 can be inserted into the supporting groove 5201 and locked with the supporting mechanism.

[0058] Furthermore, a locking bevel groove 2201 is provided on one side of the crossbar 22. When the crossbar 22 is inserted into the through groove 501 and corresponds to the position of the bearing groove 5201, the bearing mechanism moves upward, so that the locking bevel block 71 is squeezed and inserted into the locking bevel groove 2201, and the crossbar 22 is locked. Specifically, when the bearing mechanism is locked with the upper mold 5, the crossbar 22 is in the bearing groove 5201. The bearing groove 5201 restricts the crossbar 22, so that the crossbar 22 is restricted in the upper and left and right directions. Then, the locking bevel block 71 cooperates with the locking bevel groove 2201 to restrict the crossbar 22 in the downward direction, that is, the locking between the crossbar 22 and the upper mold 5 can be achieved in all directions, which greatly improves the stability of the upper mold 5 during transportation.

[0059] In the embodiment further provided by the present invention, a locking piece is further included in the upper mold 5, and when the upper mold 5 is molded with the lower mold 4, the locking piece is locked on the lower mold 4. The locking piece provided in the present invention can drive the locking piece in the upper mold 5 to lock with the lower mold 4 during the unlocking process, that is, the locking stability between the upper mold 5 and the lower mold 4 can be improved.

[0060] In an embodiment further provided by the present invention, the interlocking member comprises a pull rod 8 slidably disposed on the upper mold 5, and a connecting column 81 is disposed at one end of the pull rod 8, and the connecting column 81 is located in a connecting groove 701 provided on the slider 7;

[0061] A locking block 83 is also provided at one end of the pull rod 8 away from the connecting column 81;

[0062] The lower mold 4 is provided with a connecting piece, and when the upper mold 5 and the lower mold 4 are closed, the locking block 83 is locked on the connecting piece.

[0063] In an embodiment further provided by the present invention, the connecting member includes a fixing column 42 fixedly arranged on the lower mold 4, and a locking groove 4201 adapted to the locking block 83 is opened on the fixing column 42. When the upper mold 5 and the lower mold 4 are molded together, the fixing column 42 passively drives the locking member to disengage from the locking inclined groove 2201 to unlock the lock with the horizontal column 22;

[0064] A first elastic member 82 is provided at one end of the pull rod 8, and one end of the first elastic member 82 abuts against the pull rod 8, and the other end abuts against the upper mold 5; when the locking block 83 is located at the notch position of the locking groove 4201, the elastic force of the first elastic member 82 can drive the locking block 83 to be inserted into the locking groove 4201 to lock the fixing column 42. The specific present invention has two core effects through the use of the connecting parts and the interlocking parts. First, when the upper mold 5 and the lower mold 4 are closed, the slider 7 can be passively squeezed so that the locking bevel block 71 on the slider 7 disengages from the locking bevel groove 2201, so that the upper mold 5 is separated from the cross column 22. At this time, the cross column 22 can be completely separated from the upper mold 5 by controlling the load-bearing rod 21 to move downward, that is, the upper mold 5 can be passively driven to separate from the load-bearing mechanism, which greatly simplifies the replacement time and facilitates the load-bearing mechanism to cast the next mold; second, while the fixed column 42 squeezes the pull rod 8, the locking block 83 can be locked with the locking groove 4201, that is, the lock block 83, the locking groove 4201 and the fixed column 42 can cooperate to achieve passive locking during the closing process of the upper mold 5 and the lower mold 4, thereby improving the stability between the upper mold 5 and the lower mold 4.

[0065] The solution further provided by the present invention also includes an unlocking member arranged in the horizontal column 22, which is used to unlock the upper mold 5 and the lower mold 4 when demolding, and the unlocking member includes a movable column 6 slidably arranged in the horizontal column 22, and one end of the movable column 6 can penetrate and extend out of the horizontal column 22, and an adjustment fixing member is arranged on the horizontal column 22, and the adjustment fixing member includes a moving block 61 vertically slidably arranged on the movable column 6, and a lock buckle 611 is elastically slidably arranged on the moving block 61. Specifically, in the present application, a third elastic member 612 is arranged between the lock buckle 611 and the moving block 61, and under its elastic force, the lock buckle 611 can be inserted into the first lock groove 6102 or the second lock groove 6103.

[0066] In the solution further provided by the present invention, a first locking groove 6102 and a second locking groove 6103 which are compatible with the lock buckle 611 are provided on the horizontal column 22, and the lock buckle 611 has a first state and a second state. In the first state, the lock buckle 611 is in the first locking groove 6102, and the movable column 6 is completely in the horizontal column 22. In the second state, the lock buckle 611 is in the second locking groove 6103, and the movable column 6 completely protrudes to the horizontal column 22, and can squeeze the locking bevel block 71 to move toward the upper mold 5 again, so that the locking block 83 disengages from the locking groove 4201.

[0067] In the solution further provided by the present invention, a guide groove 6101 is provided on the moving block 61, and an unlocking rod 62 is slidably provided in the movable column 6, and a column at one end of the unlocking rod 62 is located in the guide groove 6101;

[0068] A slot 5202 is also provided on the upper mold 5 , and a wedge block 53 is also provided on the upper mold 5 , and the wedge block 53 forms a first extrusion slope 531 and a second extrusion slope 532 upward; a fixed block 43 is also provided on the upper mold 5 , and the fixed block 43 is used to squeeze the lock buckle 611 to shrink into the moving block 61 .

[0069] Specifically, the present invention, through the setting of the unlocking component and the setting of the adjusting fixing part, can make it possible for the lock buckle 611 to be passively disengaged from the bearing groove 5201 through the above-mentioned structure when the mold is removed after the casting is completed, so as to facilitate the separation of the upper mold 5 and the lower mold 4. That is, through the use of the above-mentioned overall structure, not only the locking stability of the upper mold 5 and the lower mold 4 when the mold is closed can be ensured, but also the passive unlocking can be achieved when the mold is removed, so as to realize the separation of the upper mold 5 and the lower mold 4.

[0070] When the present invention is used, first, the lower mold 4 is directionally transported by the provided conveying guide rail 41, and the upper mold 5 is provided on the second conveying frame 3 and moves along the second conveying frame 3. During the movement, the lower mold 4 is transported to the specified position. Then, after the upper mold 5 is transported to the specified position, the sliding rod 2 drives the bearing rod 21 to move downward and is located at the notch position of the through groove 501, and then drives the bearing rod 21 to move horizontally, slides through the through groove 501 to the bottom of the bearing block 52, and at this time the lock buckle 611 does not contact the fixed block 43, and then the bearing rod 21 moves upward, that is, , driving the cross column 22 to move upward synchronously, and making the cross column 22 in the bearing groove 5201. During the upward movement of the cross column 22, the cross column 22 gradually squeezes the locking bevel 71, and finally makes the locking bevel 71 correspond to the locking bevel groove 2201 in the cross column 22, and then under the elastic force of an elastic member, the locking bevel 71 is inserted into the locking bevel groove 2201, thereby fixing the cross column 22 and the upper mold 5, and then continuing to move upward, the bearing rod 21 drives the upper mold 5 to move upward and separate from the second conveying frame 3, and then the bearing rod 21 drives the upper mold 5 along Figure 2 The upper mold 5 and the lower mold 4 are completely molded together, and the locking block 83 is at the notch position of the locking groove 4201. Then, the elastic force of the first elastic member 82 drives the locking block 83 to be inserted into the locking groove 4201, that is, the locking block 71 is driven to be disengaged from the locking groove 2201, and then the bearing rod 21 moves downward to gradually close the upper mold 5 and the lower mold 4. In the process of closing the upper mold 5 and the lower mold 4, the fixing column 42 is gradually inserted into the groove of the upper mold 5, and then the fixing column 42 contacts the locking block 83. Since the fixing column 42 is inclined, in the process of contacting the locking block 83, the locking block 83 is gradually squeezed to move in the direction away from the locking bevel block 71, that is, it can drive the locking bevel block 71 to gradually disengage from the locking bevel groove 2201. At this time, the upper mold 5 and the lower mold 4 are completely closed, and the locking block 83 is at the notch position of the locking groove 4201. Then, the elastic force of the first elastic member 82 drives the locking block 83 to be inserted into the locking groove 4201, that is, the locking of the upper mold 5 and the lower mold 4 is realized, and at the same time, the locking bevel block 71 is driven to disengage from the locking bevel groove 2201, and then the bearing rod 21 moves downward and disengages from the bearing groove 5201, so as to realize the locking of the upper mold and the lower mold.

[0071] When disassembling after pouring is completed, the bearing rod 21 is inserted into the through groove 501 according to the above-mentioned stroke. At this time, the downward movement distance of the bearing rod 21 can make the fixed block 43 pass through the avoidance groove 2203 and contact the lock buckle 611 during the sliding process of the bearing rod 21. Then, the lock buckle 611 is disengaged from the lock and retracted into the moving block 61 during the sliding process. Then, under the elastic force of the second elastic member 63, the movable column 6 moves toward the locking inclined groove 2201 and protrudes onto the cross column 22. The movable column 6 is inserted into the slot 5202. Then the bearing block 52 moves upward again, driving the cross column 22 and the movable column 6 to move upward synchronously. Since the movable column 6 protrudes into the slot 5202, it can squeeze the locking inclined block 71 during the upward movement, so that the locking inclined block 71 moves inward again toward the direction of the upper mold 5, which can drive the lock buckle 611 to disengage from the locking groove 4201. Then the bearing rod 21 continues to move upward, which can synchronously drive the upper mold 5 to move upward, that is, to achieve demolding.

[0072] Finally, the carrying rod 21 places the mold on the second conveying rack 3, and then the carrying rod 21 moves downward again, horizontally disengaging from the carrying groove 5201, and then the carrying rod 21 moves toward the direction of the wedge block 53. During the movement, the unlocking rod 62 on the movable column 6 gradually squeezes the second extrusion slope 532, and the unlocking rod 62 contracts inward. At this time, the unlocking rod 62 contracts inward. Due to the effect of the guide groove 6101, the unlocking rod 62 gradually squeezes the moving block 61 upward during the inward contraction process, so that the moving block 61 can be disengaged from the second locking groove 6103, and then continue to move. During the movement, the movable column 6 gradually squeezes the first extrusion slope 531 on the wedge block 53, and the first extrusion slope 531 gradually squeezes the movable column 6 to move inward in the direction of the horizontal column 22, and is finally completely squeezed into the horizontal column 22. The delivery groove 2202 provided on the horizontal column 22 is used to avoid the wedge block 53, and the lock buckle 611 is at the notch position of the first lock groove 6102 at this time, and then the lock buckle 611 is inserted into the first lock groove 6102 under the elastic force of the third elastic member 612, which can make the movable column 6 shrink into the horizontal column 22 again, so as to facilitate the next load on the upper mold 5.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
