Description

Technical Field

[0001] This invention relates to a modular building forming equipment, and more particularly to a modular building forming equipment with a flat top that facilitates operator movement. Background Technology

[0002] The top structure of current modular building forming equipment (house construction equipment) has obvious defects: manufacturers usually install multiple tie rod mechanisms (i.e., tension rod mechanisms) on the top of the modular building forming equipment to prevent box expansion. These tie rod mechanisms not only occupy the space on the top of the modular building forming equipment, reducing the convenience of operators moving on the top, but also increase the difficulty of operation; moreover, when the top covering film (such as covering cloth) is needed later, the tie rod mechanism will become an obstacle, making it difficult to cover and roll up the covering film, affecting the efficiency of operation; at the same time, the complex tie rod mechanism also increases the safety hazards for operators walking on the top, reducing the safety of using modular building forming equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a modular building forming device with a flat top that facilitates operator movement. The top of the forming mold does not require a tie rod mechanism to avoid the problem of box expansion. The top of the forming mold can be flat, which facilitates the formation of a safe passage. This solves the problem of poor safety and low operating efficiency caused by operators having difficulty avoiding obstacles such as tie rod mechanisms on the top of the forming mold.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A modular building forming device with a flat top for easy operator movement includes an inner mold, two outer molds located on the left and right sides of the device, two end molds located at the front and rear ends, and a bottom mold. The inner mold comprises two inner side molds, two inner end molds, an inner top mold, four corner molds, and a steel frame connected thereto. One of the end molds also has a laminating machine for applying a film to the top. An outer mold locking mechanism is provided at each of the eight corners formed by the two outer side molds and the two end molds. The technical solution lies in that the modular building forming device with a flat top for easy operator movement also includes two clamping mechanisms located on the left and right sides of the forming mold for locking the inner and outer side molds.

[0005] Each of the outer mold locking mechanisms has a first hydraulic cylinder that prevents the outer mold from moving outward when it is pulled together with the end mold, a second hydraulic cylinder that prevents the end mold from moving outward when it is connected with the outer mold, a limit plate, a limit body, a plug, and a positioning body with a socket fixed to a corresponding outer mold.

[0006] The above-mentioned outer mold and end mold being tightened together refers to the left outer mold being tightened together with the front mold, the right outer mold being tightened together with the front mold, the left outer mold being tightened together with the rear mold, and the right outer mold being tightened together with the rear mold. The above-mentioned outer mold and end mold being connected (fixed) together refers to the left outer mold being connected together with the front mold, the right outer mold being connected together with the front mold, the left outer mold being connected together with the rear mold, and the right outer mold being connected together with the rear mold.

[0007] In the above technical solution, a preferred technical solution may be that each clamping mechanism has a fixed base, a hydraulic cylinder, a left clamping block, a right clamping block, a left connecting arm, a right connecting arm, a left connecting rod, a right connecting rod, and a support fixedly installed on the fixed base; in each clamping mechanism, the top end of the piston rod of the hydraulic cylinder and the bottom end of the cylinder barrel are respectively hinged to the inner ends of the corresponding left connecting arm and the right connecting arm; the middle positions of the left connecting arm and the right connecting arm are respectively hinged to the left and right ends of the corresponding support; the outer ends of the left connecting arm and the right connecting arm are respectively hinged to the non-clamping head ends of the corresponding left clamping block and the right clamping block; the clamping head ends of the left clamping block and the right clamping block are respectively hinged to the outer ends of the corresponding left connecting rod and the right connecting rod; and the inner ends of the left connecting rod and the right connecting rod are respectively hinged to the support.

[0008] In the above technical solution, a preferred embodiment may also be that the fixed base is fixed to the foundation; the support is arranged laterally, passing through the fixed base and located above it; the hydraulic cylinder is arranged laterally and located below the support; the left connecting arm is Z-shaped, and the right connecting arm is symmetrical to the left connecting arm; the left clamping block and the right clamping block are symmetrical to each other, and the left connecting rod and the right connecting rod are symmetrical to each other. Both the left and right connecting rods consist of two rods, with the two rods of the left connecting rod located on the front and rear sides of the support, and the two rods of the right connecting rod located on the front and rear sides of the support.

[0009] In this invention, when each clamping mechanism is in operation, the piston rod of the hydraulic cylinder extends outward, pushing the left connecting arm to rotate clockwise around the support. This causes the end face (clamping working surface) of the clamping head of the left clamping block to be in a longitudinal position and apply a force (clamping force) to the outer mold. Simultaneously, with the help of the reaction force of the hydraulic cylinder, the cylinder barrel pushes the right connecting arm to rotate counterclockwise around the support. This causes the end face (clamping working surface) of the clamping head of the right clamping block to be in a longitudinal position and apply a force (clamping force) to the inner mold, thereby locking the inner and outer molds and preventing component deformation or even slurry leakage. When the mold is opened, only the hydraulic cylinder needs to be depressurized, and the piston rod of the hydraulic cylinder retracts, releasing the clamping mechanism's locking restriction on the inner and outer molds. The inner and outer molds are then in a loose state. In this way, the two clamping mechanisms can effectively prevent locking, and even slight deformation of the component will not affect the output of the component. In this invention, the clamping mechanism has been changed from the original rotating structure to a clamping structure. When the mold is opened, the clamping mechanism will not interfere with the inner mold and the outer mold, and it is easy to reset, thus effectively solving the problem of locking up when the mold is opened.

[0010] In the above technical solution, a preferred technical solution may also be that, in each of the outer mold locking mechanisms, the cylinder barrels of the first hydraulic cylinder and the second hydraulic cylinder are fixedly installed on a corresponding end mold, and the limiting plate used in conjunction with the first hydraulic cylinder is fixedly installed on a corresponding outer mold. The first piston rod of the first hydraulic cylinder passes through the through hole of the limiting plate, and a limiting body is fixedly fixed at the top of the first piston rod of the first hydraulic cylinder. When the outer mold and the end mold are pulled together and are in a tensioned state, the limiting body is unilaterally limited by the side wall of the limiting plate, thereby pulling the outer mold and preventing the outer mold from moving outward. The top of the second piston rod of the second hydraulic cylinder is fixedly connected to a plug. When the outer mold and the end mold are connected together and are in a fixed state, the plug is inserted into the insertion hole of the positioning body to prevent the end mold from moving outward.

[0011] In the above technical solution, a preferred technical solution is that the perforation is a U-shaped hole. The structure in which the top of the second piston rod of the second hydraulic cylinder is fixedly connected to a plug is as follows: the top of the second piston rod of the second hydraulic cylinder is connected by a threaded connection to a horizontally arranged connecting sleeve; the plug is horizontally arranged; a horizontally arranged guide sleeve is fixed to the end mold; the plug passes horizontally through the guide sleeve; the plug, which can slide along the guide sleeve, is limited and supported by the guide sleeve; one end of the plug extends into the connecting sleeve and is connected to the connecting sleeve by a pin; the pin is vertically arranged; when the outer mold and the end mold are connected together and in a fixed state, the other end of the plug is inserted into the insertion hole of the positioning body. Using a pin connection method increases the degree of freedom in connecting the plug and the second piston rod, and makes it easier for one end (outer end) of the plug to be inserted into the insertion hole of the positioning body. A guardrail is fixedly installed around the top of the forming mold by welding or bolting; the top of the forming mold has a safety passage inside the guardrail.

[0012] It should be noted that each of the four corners formed by the two outer molds and the one end mold (the front mold) has an outer mold locking mechanism, resulting in a total of four (front-side) outer mold locking mechanisms. These four (front-side) outer mold locking mechanisms are symmetrical vertically and horizontally. Similarly, each of the four corners formed by the two outer molds and the one end mold (the rear mold) has an outer mold locking mechanism, resulting in a total of four (rear-side) outer mold locking mechanisms. These four (rear-side) outer mold locking mechanisms are symmetrical vertically and horizontally.

[0013] The working principle of the outer mold locking mechanism in this invention is as follows: the first hydraulic cylinder on the end mold pulls the outer mold tight, while the second piston rod of the second hydraulic cylinder is inserted into the insertion hole of the positioning body, fixing the positioning body to the side mold and thus fixing the position of the end mold. The specific operation process is as follows: ① First, the two outer molds are closed in place, and then the first piston rod of the first hydraulic cylinder extends. ② When the end molds are closed, the first piston rod of the first hydraulic cylinder moves into the through hole (the through hole is a U-shaped hole) of the limiting plate on the outer mold, and then the first piston rod of the first hydraulic cylinder retracts, pulling the outer mold tight. ③ After the end molds are closed in place, the second piston rod of the second hydraulic cylinder on the end mold extends. The second piston rod of the second hydraulic cylinder pushes the plug with the help of the connecting sleeve and the pin. The plug slides outward along the guide sleeve, and one end of the plug (the outer end) is inserted into the insertion hole of the positioning body, thus fixing the position of the end mold. In addition, two fixing holes can be provided on the outer mold to facilitate the fixing of the rear mold with the addition of the outer mounting plate.

[0014] This invention changes the connection structure (style) between the end mold and the outer mold. Previously, the outer mold connection was corner-to-corner, mainly secured by an external locking structure. The outer mold locking mechanism used in this invention encloses the end mold within the outer mold, and the locking mechanism itself is concealed within the end mold. The advantages of this different structure are that it eliminates the tedious manual positioning. When connecting the outer mold and the end mold, the outer mold locking mechanism (using automatic positioning and automatic locking by a hydraulic cylinder) can automatically and accurately position itself, completing the connection without manual intervention. This solves the problem of inaccurate positioning and time-consuming manual intervention required when connecting the outer mold and the end mold. Simultaneously, the side mold is lengthened, and two positioning holes (fixing holes) are opened on the side mold, which can be used to install an external mounting plate on the outer mold.

[0015] This invention, by incorporating a clamping mechanism and an outer mold locking mechanism, offers reliable operation and each possesses its own advantages (see the above discussion). This eliminates the need for a tie rod mechanism (i.e., a tension rod mechanism) on the top of the molding mold, preventing expansion issues and resulting in a flat top. Simultaneously, a guardrail is fixedly installed around the top of the molding mold, forming a safety passage within the guardrail. The flat top structure facilitates operator movement, while the guardrail provides safety protection, enhancing operational safety. Furthermore, this invention offers high operational convenience; the flat top and absence of tie rods (or pull rods) facilitate operator movement and various operations. Moreover, this invention facilitates the covering and winding of the covering fabric by a covering fabric winding machine or manually, improving operational efficiency. Additionally, the elimination of the tie rod mechanism enhances safety; the safety passage and guardrail around the top provide operator safety protection, reducing safety hazards. Its simple structure, eliminating the need for a tie rod mechanism, simplifies the top structure of the molding mold, reduces the number of parts, and lowers the manufacturing and maintenance costs of the molding mold (equipment). According to experiments, compared with related technologies, the manufacturing and maintenance costs of this invention are reduced by more than 12%, and the operating efficiency is increased by more than 10%.

[0016] In summary, the present invention provides a modular building forming equipment with a flat top that facilitates operator movement. The top of the forming mold does not require a tie rod mechanism to avoid the problem of box expansion. The top of the forming mold can be flat, which facilitates the formation of a safe passage. This solves the problem of poor safety and low operating efficiency caused by operators having difficulty avoiding obstacles such as tie rod mechanisms on the top of the forming mold.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the modular building forming equipment of the present invention, with a flat top for easy operator movement, includes an inner mold, two outer molds 2 located on the left and right sides of the modular building forming equipment, two end molds 3 located at the front and rear ends of the modular building forming equipment, a bottom mold 20, and a cover fabric winding machine 4. The inner mold includes two inner molds 1, two inner end molds, an inner top mold, four corner molds, and a steel frame connected thereto. An outer mold locking mechanism 7 is provided at each of the eight corners formed by the two outer molds 2 and the two end molds 3. The modular building forming equipment with a flat top for easy operator movement also includes two clamping mechanisms 8 located on the left and right sides of the forming mold for locking the inner molds 1 and outer molds 2.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, each of the outer mold locking mechanisms 7 includes a first hydraulic cylinder 9 that prevents the outer mold from moving outward when the outer mold 2 is tightly fastened to the end mold 3, a second hydraulic cylinder 10 that prevents the end mold from moving outward when the outer mold 2 is connected to the end mold 3, a limiting plate 18, a limiting body 19, a plug 13, and a positioning body 16 with a socket 16a fixed to a corresponding outer mold. The phrase "outer mold 2 and end mold 3 are fastened together" refers to the left outer mold being fastened to the front mold, the right outer mold being fastened to the front mold, the left outer mold being fastened to the rear mold, and the right outer mold being fastened to the rear mold. The phrase "outer mold 2 and end mold 3 are connected (fixed) together" refers to the left outer mold being connected to the front mold, the right outer mold being connected to the front mold, the left outer mold being connected to the rear mold, and the right outer mold being connected to the rear mold.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, each clamping mechanism 8 has a fixed base 81, a hydraulic cylinder 85, a left clamping block 87, a right clamping block 83, a left connecting arm 86, a right connecting arm 84, a left connecting rod 88, a right connecting rod 82, and a support 89 fixedly installed on the fixed base 81. In each clamping mechanism 8, the top end of the piston rod of the hydraulic cylinder 85 and the bottom end of the cylinder barrel of the hydraulic cylinder 85 are respectively hinged to the inner ends of the corresponding left connecting arm 86 and right connecting arm 84; the middle positions of the left connecting arm 86 and right connecting arm 84 are respectively hinged to the left and right ends of the corresponding supports 89; the outer ends of the left connecting arm 86 and right connecting arm 84 are respectively hinged to the non-clamping head ends of the corresponding left clamping block 87 and right clamping block 83; the clamping head ends of the left clamping block 87 and right clamping block 83 are respectively hinged to the outer ends of the corresponding left connecting rod 88 and right connecting rod 82; the inner ends of the left connecting rod 88 and right connecting rod 82 are respectively hinged to the supports 89. The fixed base 81 is fixed to the foundation. The aforementioned support 89 is arranged laterally, passing through the fixed base 81 and located above the fixed base 81; the hydraulic cylinder 85 is arranged laterally and located below the support 89; the aforementioned left connecting arm 86 is Z-shaped, and the right connecting arm 84 is symmetrical to the left connecting arm 86; the aforementioned left clamping block 87 and right clamping block 83 are symmetrical to each other, and the left connecting rod 88 and right connecting rod 82 are symmetrical to each other. Both the left connecting rod 88 and the right connecting rod 82 consist of two rods, with the two rods of the left connecting rod 88 located on the front and rear sides of the support 89, and the two rods of the right connecting rod 82 located on the front and rear sides of the support 89.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, in this invention, when each clamping mechanism 8 is working, the piston rod of the hydraulic cylinder 85 extends outward, and the piston rod pushes the left connecting arm 86 to rotate clockwise around the support 89, so that the end face (clamping working surface) of the clamping head of the left clamping block 87 is in a longitudinal state and applies a force (clamping force) to the outer mold 2; at the same time, with the help of the reaction force of the hydraulic cylinder 85, the cylinder of the hydraulic cylinder 85 pushes the right connecting arm 84 to rotate counterclockwise around the support 89, so that the end face (clamping working surface) of the clamping head of the right clamping block 83 is in a longitudinal state and applies a force (clamping force) to the inner mold 1, thereby locking the inner mold 1 and the outer mold 2 to prevent the deformation of the components or even the leakage of grout. When the mold is opened, only the hydraulic cylinder needs to be depressurized, and the piston rod of the hydraulic cylinder 85 retracts, releasing the locking restriction of the clamping mechanism 8 on the inner mold 1 and the outer mold 2. The inner mold 1 and the outer mold 2 are in a loose state. In this way, the two clamping mechanisms 8 can effectively prevent the occurrence of locking. Even if the component is slightly deformed, it will not affect the production of the component. In this invention, the clamping mechanism 8 has been changed from the original rotating structure to a clamping structure. When the mold is opened, the clamping mechanism 8 will not interfere with the inner mold and the outer mold, and it is easy to reset, thus effectively solving the problem of locking during mold opening.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in each of the outer mold locking mechanisms 7, the cylinder barrels of the first hydraulic cylinder 9 and the second hydraulic cylinder 10 are fixedly installed on a corresponding end mold 3. The limiting plate 18, which works in conjunction with the first hydraulic cylinder, is fixedly installed on a corresponding outer mold 2. The first piston rod 17 of the first hydraulic cylinder 9 passes through the through hole 18a of the limiting plate 18. The top of the first piston rod 17 of the first hydraulic cylinder 9 is fixed with a limiting body 19. When the outer mold 2 and the end mold 3 are pulled together and are in a tensioned state, the limiting body 19 is unilaterally limited by the side wall of the limiting plate 18, thereby pulling the outer mold 2 and preventing the outer mold 2 from moving outward. The top of the second piston rod 11 of the second hydraulic cylinder 10 is fixedly connected with a plug 13. When the outer mold 2 and the end mold 3 are connected together and are in a fixed state, the plug 13 is inserted into the insertion hole 16a of the positioning body 16 to prevent the end mold 3 from moving outward.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the perforation 18a is a U-shaped hole. The structure where the top of the second piston rod 11 of the second hydraulic cylinder 10 is fixedly connected to the plug 13 is as follows: the top of the second piston rod 11 of the second hydraulic cylinder 10 is connected by a threaded connection to a horizontally arranged connecting sleeve 12. The plug 13 is horizontally arranged, and a horizontally arranged guide sleeve 14 is fixed to the end mold 3. The plug 13 passes through the guide sleeve 14 and can slide along the guide sleeve 14, which limits and supports it. One end of the plug 13 extends into the connecting sleeve 12 and is connected to the connecting sleeve 12 through a pin 15. The pin 15 is vertically arranged. When the outer mold 2 and the end mold 3 are connected together and in a fixed state, the other end of the plug 13 is inserted into the insertion hole 16a of the positioning body 16. Using the pin 15 connection method increases the degree of freedom in connecting the plug 13 to the second piston rod 11, making it easier for one end (outer end) of the plug 13 to be inserted into the insertion hole 16a of the positioning body 16. The top perimeter of the molding mold is fixedly installed with guardrails 5 by welding or bolting, and the top of the molding mold has a safety passage 6 inside the guardrails 5.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, it should be noted that each of the four front corners formed by the two outer molds 2 and one end mold 3 (which is the front end mold) is provided with an outer mold locking mechanism 7, for a total of four (front-side) outer mold locking mechanisms. These four (front-side) outer mold locking mechanisms are symmetrical vertically and horizontally. Similarly, each of the four rear corners formed by the two outer molds 2 and one end mold 3 (which is the rear end mold) is provided with an outer mold locking mechanism 7, for a total of four (rear-side) outer mold locking mechanisms. These four (rear-side) outer mold locking mechanisms are symmetrical vertically and horizontally.

[0032] In this invention, the outer mold locking mechanism 7 works by using the first hydraulic cylinder 9 on the end mold 3 to tighten the outer mold 2, while simultaneously inserting the second piston rod 11 of the second hydraulic cylinder 10 into the insertion hole 16a of the positioning body 16. The positioning body 16 is fixed to the outer mold 2, thus fixing the position of the end mold 3. The specific operation process is as follows: ① First, the two outer molds 2 are closed in place, and then the first piston rod 17 of the first hydraulic cylinder 9 extends. ② When the end mold 3 is closed, the first piston rod 17 of the first hydraulic cylinder 9 moves into the through hole 18a (the through hole 18a is a U-shaped hole) of the limiting plate 18 on the outer mold 2, and then the first piston rod 17 of the first hydraulic cylinder 9 retracts, tightening the outer mold 2. ③ After the end mold 3 is closed in place, the second piston rod 11 of the second hydraulic cylinder 10 on the end mold 3 extends. The second piston rod 11 of the second hydraulic cylinder 10 pushes the plug 13 with the help of the connecting sleeve 12 and the pin 15. The plug 13 slides outward along the guide sleeve 14, and one end (outer end) of the plug 13 is inserted into the insertion hole 16a of the positioning body 16, thus fixing the position of the end mold 3. In addition, two fixing holes can be provided on the outer mold to facilitate the fixing of the rear mold of the outer mounting plate.

[0033] This invention changes the connection structure (style) between the end mold and the outer mold. Previously, the outer mold connection was corner-to-corner, mainly secured by an external locking structure. The outer mold locking mechanism used in this invention encloses the end mold within the outer mold, and the locking mechanism itself is concealed within the end mold. The advantages of this different structure are that it eliminates the tedious manual positioning. When connecting the outer mold and the end mold, the outer mold locking mechanism (using automatic positioning and automatic locking by a hydraulic cylinder) can automatically and accurately position itself, completing the connection without manual intervention. This solves the problem of inaccurate positioning and time-consuming manual intervention required when connecting the outer mold and the end mold. Simultaneously, the outer mold is lengthened, and two positioning holes (fixing holes) are opened on it, allowing for the installation of an external mounting plate.

[0034] This invention, by incorporating a clamping mechanism 8 and an outer mold locking mechanism 7, ensures reliable operation and possesses its own advantages (see the above discussion). This eliminates the need for a tie rod mechanism (i.e., a tension rod mechanism) on the top of the molding mold, preventing expansion issues and resulting in a flat top. Simultaneously, a guardrail is fixedly installed around the top of the molding mold, forming a safety passage within the guardrail. The flat top structure facilitates operator movement, while the guardrail provides safety protection, enhancing operational safety. Furthermore, this invention offers high operational convenience; the flat top, free from tie rods (or pull rods), facilitates operator movement and various operations. Moreover, it facilitates the covering and winding of the covering fabric by a covering fabric winding machine or manually, improving operational efficiency. Additionally, the elimination of the tie rod mechanism enhances safety; the safety passage and guardrail around the top provide operator protection and reduce safety hazards. Its simple structure, eliminating the need for a tie rod mechanism, simplifies the top structure of the molding mold, reduces the number of parts, and lowers the manufacturing and maintenance costs of the molding mold (equipment). According to experiments, compared with related technologies, the manufacturing and maintenance costs of this invention are reduced by more than 12%, and the operating efficiency is increased by more than 10%.

[0035] In summary, the present invention provides a modular building forming equipment with a flat top that facilitates operator movement. The top of the forming mold does not require a tie rod mechanism to avoid the problem of box expansion. The top of the forming mold can be flat, which facilitates the formation of a safe passage. This solves the problem of poor safety and low operating efficiency caused by operators having difficulty avoiding obstacles such as tie rod mechanisms on the top of the forming mold.
