Detailed implementation mode

[0033] The present utility model will be further described in detail below in conjunction with the drawings and embodiments, but it shall not be used as a basis for any limitation to the utility model.

[0034] As Figure 1 shown, a precast refractory vibration forming device includes a vibration machine room 1, in which a vibration table 2, a track 3 and a cloth feeding mechanism 4 are arranged. The vibration table 2 is arranged between two tracks 3 and is used to support the mold trolley for vibration forming after casting; the mold trolley enters and exits the vibration machine room 1 through the track 3; the cloth feeding mechanism 4 is arranged at the upper part of the vibration machine room 1. The cloth feeding mechanism 4 is used to receive the mud required for casting and put the mud into the forming mold of the lower mold trolley. Therefore, a blanking port is arranged at the top of the vibration machine room 1 for the material transportation trolley to put the mud into the cloth feeding mechanism 4.

[0035] The structure of the vibration table will be described in detail below in conjunction with the attached Figures 2 - 5 drawings.

[0036] As Figure 2 shown, the vibration table 2 includes a frame composed of two longitudinal beams 201 and four cross beams 202, multiple vibration motors 205 and a jacking mechanism installed at the bottom of the frame, and a hydraulic locking mechanism installed on the cross beam 202.

[0037] The longitudinal beam 201 is parallel to the track 3, and both ends of the cross beam 202 are fixedly connected to the two longitudinal beams 201. The cross beam 202 is composed of two steel plates connected at intervals face to face, and an installation space for accommodating the hydraulic locking mechanism is formed between the two steel plates.

[0038] The vibration motor 205 is fixed on the bottom surface of the longitudinal beam 201. In this embodiment, four vibration motors 205 are installed at the bottom of each longitudinal beam 201. In other implementation modes, the number of vibration motors 205 can be selected according to design requirements or the length of the longitudinal beam 201.

[0039] Both ends of the longitudinal beam 201 are also respectively supported on a jacking mechanism, and the jacking mechanism is an airbag assembly 206. The upper end of the airbag assembly 206 is connected to the longitudinal beam 201, and the lower end is connected to a base 207 fixed on the ground of the vibrating machine room 1. After the airbag assembly 206 is inflated, it can lift the frame, so that the die trolley on the vibrating table 2 is lifted and separated from the track 3, avoiding damage to the track 3 or the running wheels of the die trolley during vibration. A limit chain 208 is also connected between the end of the longitudinal beam 201 and the base 207, and the length of the limit chain 208 can control the height to which the vibrating table 2 is lifted. Guide rods 209 are also provided on the outer sides of the two cross beams 202 at both sides. The guide rods 209 are fixed on the corresponding mounting seats 211 and are perpendicular to the ground, providing guidance for the jacking of the vibrating table 2. In order to prevent the guide rods 209 from wearing the cross beam 202, guide plates 212 are fixed on the outer side of the cross beam 202 with screws. By the contact of the guide plates 212 at both ends with the guide rods 209, the vertical lifting of the vibrating table 2 is ensured.

[0040] In other embodiments, other forms of jacking mechanisms can also be used to replace the airbag assembly 206. For example, an oil cylinder can be used to replace the airbag assembly 206.

[0041] In other embodiments, the limit chain 208 or other limit mechanisms can also be not provided. Only by strictly controlling the inflation amount of each airbag assembly 206, the lifting height of the vibrating table 2 can also be accurately controlled to avoid the vibrating table 2 being too high.

[0042] The airbag assembly 206 includes an airbag body 2061, a top lining plate 2062 and a bottom lining plate 2063. The upper end of the airbag body 2061 is connected to the top lining plate 2062, and the lower end is connected to the bottom lining plate 2063. The top lining plate 2062 is connected to the bottom surface of the longitudinal beam 201 by bolts, and the bottom lining plate 2063 is connected to the base 207 by bolts 210. An air inlet and outlet is provided at the bottom of the airbag body 2061, and the air inlet and outlet passes through the bottom lining plate 2063 and is connected to an external air source. The setting of the top lining plate 2062 and the bottom lining plate 2063 can, on the one hand, enhance the rigidity of the airbag body 2061, avoid direct friction between the airbag body 2061 and the longitudinal beam 201 and the base 207, thereby protecting the airbag body 2061, and on the other hand, can also avoid the vibrating table 2 from tilting during the inflation and jacking process of the airbag body 2061. After the airbag body 2061 is inflated, it plays a role of jacking and supporting on the one hand, making the die trolley separate from the track, and on the other hand, during vibration, the airbag body 2061 can reduce vibration noise and improve the working environment.

[0043] The hydraulic locking mechanism includes a hydraulic cylinder 203 and a locking block 204. The cylinder block of the hydraulic cylinder 203 is rotatably connected within the installation space of the cross beam 202 through a hinge seat, and the piston rod of the hydraulic cylinder 203 is rotatably connected to the lower end of the locking block 204. A rotating shaft is provided in the middle of the locking block 204 and is supported on two steel plates forming the cross beam 202. The upper end of the locking block 204 is the locking end. Both the hydraulic cylinder 203 and the locking block 204 are inclined, forming a V-shaped layout to enhance the stability after locking the die trolley.

[0044] On the vibrating table, the number of the hydraulic locking mechanisms provided is the same as that of the cross beams 202, and one hydraulic locking mechanism is provided within the installation space of each cross beam 202. Moreover, the locking blocks 204 of at least one hydraulic locking mechanism and the other locking blocks 204 are arranged on opposite sides with respect to the longitudinal center line of the vibrating table 2. In this way, after the piston rod of the hydraulic cylinder 203 extends out, it pushes the locking block 204 to rotate. The upper end of the locking block 204 rotates towards the inside of the vibrating table 2 and gets stuck on the rib on the bottom of the die trolley. After the locking blocks 204 on the vibrating table 2 are arranged on opposite sides, the upper ends of the locking blocks 204 can hug the trolley from both sides after rotating towards the inside, playing the role of locking the die trolley.

[0045] Furthermore, in order to enhance the clamping force of the locking block 204 on the die trolley and make the forces on both sides of the die trolley balanced, as Figure 3 shown, the locking blocks 204 of the hydraulic locking mechanism are alternately distributed on both sides of the longitudinal center line of the vibrating table 2 along the length direction of the longitudinal beam.

[0046] The following will combine with the attached Figures 6 - 11 drawings to make a detailed description of the structural settings of the cloth feeding mechanism.

[0047] The cloth feeding mechanism 4 includes a cloth feeding frame, a cloth feeding trolley 403, a cloth hopper 404 provided on the cloth feeding trolley 403, and a lifting and vibrating mechanism 405. The cloth feeding frame includes a traveling girder 401 and a bracket 402. The traveling girder 401 is supported on the bracket 402, and the bracket 402 is fixedly connected to the inner wall of the vibrating machine room 1. The cloth feeding trolley 403 moves along the traveling girder 401. A cloth hopper 404 is fixedly provided on the body of the cloth feeding trolley 403, and the lifting and vibrating mechanism 405 is also provided on one side of the body. Among them, the movement of the cloth feeding trolley 403 and the discharging of the cloth hopper 404 are conventional settings and are not within the scope of improvement of the present utility model. Therefore, no detailed description will be given here. When implementing the present utility model specifically, the cloth feeding trolley 403 and the cloth hopper 404 on the market can be purchased.

[0048] The lifting and vibrating mechanism 405 includes a fixed frame 4051, a lifting frame 4052, a lifting drive mechanism, and vibrating rods 4054. The fixed frame 4051 is fixedly connected to the body of the cloth trolley 403. The lifting frame 4052 is connected to the fixed frame 4051 through the lifting drive mechanism. A plurality of vibrating rods 4054 are provided and are all fixed on the lifting frame 4052. After the cloth trolley 403 discharges materials onto the forming die on the die trolley, the lifting frame 4052 descends, and the vibrating rods 4054 are inserted into the mud of the forming die for vibration.

[0049] The fixed frame 4051 is an H-shaped structure formed by connecting multiple square steel bars. The lifting frame 4052 is an inverted T-shaped structure composed of square steel bars. The vertical section of the lifting frame 4052 is located between the two vertical sections of the fixed frame 4051.

[0050] The lifting drive mechanism is a worm and screw lift 4053. The worm and screw lift 4053 includes a lifting motor 4053-1, a screw rod 4053-2, a lift connecting block 4053-3, a lift connecting seat 4053-4, and a lift mounting plate 4053-5. The lifting motor 4053-1 is fixed on the horizontal section of the fixed frame 4051 through the lift mounting plate 4053-5. The screw rod 4053-2 vertically passes through the horizontal section of the fixed frame 4051. The lower end of the screw rod 4053-2 is connected to the lift connecting block 4053-3. The lift connecting seat 4053-4 is fixed on the horizontal section of the lifting frame 4052, and the lift connecting seat 4053-4 is connected to the lift connecting block 4053-3. After the lifting motor 4053-1 rotates, it drives the screw rod 4053-2 to drive the lifting frame 4052 to vertically lift and move. The lift connecting block 4053-3 and the lift connecting seat 4053-4 are connected through a pin shaft 4055, an open pin, and a flat washer for the pin shaft.

[0051] To ensure the stability of the vertical lifting of the lifting frame 4052, a guiding mechanism is further provided between the lifting frame 4052 and the fixed frame 4051, including guiding strips 4057 fixed on both sides of the vertical section of the lifting frame 4052 and a guiding wheel set installed on the vertical section of the lifting frame 4052. Four guiding wheel sets are provided. Two guiding wheel sets are provided on each side of the vertical section of the lifting frame 4052, and the guiding wheel sets on both sides are symmetrically arranged. The guiding wheel set includes guiding wheels 4056 that roll along the front, rear, and side surfaces of the guiding strip 4057 respectively. The two guiding wheels 4056 in front of and behind the guiding strip 4057 can form a clamping of the guiding strip 4057 to prevent the lifting frame 4052 from tilting forward and backward. The guiding wheels 4056 on the side surface of the guiding strip 4057 can prevent the lifting frame 4052 from tilting left and right. Thus, with the cooperation of the four guiding wheel sets and the guiding strip 4057, the vertical lifting of the lifting frame 4052 is ensured.

[0052] In other embodiments, a hydraulic lift can also be used to replace the worm and screw lift 4053. The two ends of the hydraulic lift are respectively connected to the horizontal section of the lifting frame 4052 and the horizontal section of the fixed frame 4051.

[0053] The working process of the present utility model is as follows: First, after the die trolley runs to the set position of the vibrating table 2, the hydraulic locking mechanism is started to clamp the die trolley from both sides, and the airbag assembly 206 is inflated to lift the die trolley off the ground track; then, the batching machine 403 feeds the molding die on the die trolley, and at the same time, the vibrating motor 205 is started to realize vibration while feeding; when the batching is completed, the lifting and vibrating mechanism 405 on the batching trolley 403 lowers the lifting frame 4052, and the vibrating rod 4054 is inserted into the mud material of the molding die and moves with the batching trolley 403 to realize rapid exhaust of the mud material; finally, the lifting and vibrating mechanism 405 raises the lifting frame 4052 to reset, the airbag assembly 206 deflates to lower the die trolley, the hydraulic locking mechanism releases the locking of the die trolley, and the die trolley leaves the vibrating machine room 1 along the track 3 and enters the next process.
