DETAILED DESCRIPTION

[0054] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0055] like Figures 1-12 As shown, an end mold installation and removal equipment and an end mold installation and removal method, through the mold, make it possible to produce prefabricated beams, and in the production process, no manual operation is required by the staff, which greatly reduces the labor intensity of the workers and is not easy to damage the beam body. Specifically, the mold includes a side mold 1, a bottom mold 2, an end mold 3 and an inner mold 23. There are two side molds 1 and two end molds 3. A gap is left between the two side molds 1. The bottom mold 2 and the end mold 3 are both slidably inserted in the gap. When the two side molds 1 are in the initial state (the two side molds 1 have not moved in opposite directions), a gap is left between the two side molds 1. This gap allows the bottom mold 2 to be inserted. After the bottom mold 2 is inserted, the inner mold 23 is put in. The side mold 1, the bottom mold 2 and the end mold 3 are surrounded by each other to form a mold groove. After the previous process is completed, after the steel frame is placed on the bottom mold 2, the bottom mold 2 can be moved to the gap between the two side molds 1, so that the steel frame is just in the side mold 1, the bottom mold 2 and the end mold 3. The placement of molds such as the inner mold 23 can facilitate the better formation of the beam body.

[0056] After the precast beam is produced, the side mold 1 is driven to move by the first driving mechanism and the bottom mold 2 is driven to move by the second driving mechanism, so as to achieve the purpose of automated operation and greatly improve the production efficiency. Specifically, the mold groove is arranged above the ground, and two fixed shells 4 spaced apart on the left and right are fixed on the ground. The interior of the fixed shell 4 is provided with a first driving mechanism capable of driving the two side molds 1 to move in opposite or relative directions. In this embodiment, the first driving mechanism includes a seventh hydraulic telescopic rod and a seventh slide rail. The seventh hydraulic telescopic rod is fixed on the inner side wall of the fixed shell 4, and the movable rod end face of the seventh hydraulic telescopic rod is hingedly connected to the side mold 1. The seventh slide rail is fixed on the inner bottom wall of the fixed shell 4, and the side mold 1 is slidably arranged on the seventh slide rail. Driving the seventh hydraulic telescopic rod can drive the side mold 1 to move along the seventh slide rail, so that the two side molds 1 are against the left and right sides of the bottom mold 2. A second driving mechanism capable of driving the bottom mold 2 to move is provided above the fixed shell 4. In this embodiment, the second driving mechanism includes an eighth driving device, a power wheel and a driven wheel.

[0057] Specifically, two slide rails 22 are fixed on the ground, spaced apart from each other and extending in the front-to-back direction. A movable plate 20 is slidably provided on the slide rails 22. The bottom mold 2 is fixed on the top of the movable plate 20. A chamber is provided inside the movable plate 20. An eighth drive device is fixed in the chamber (the eighth drive device is an eighth double-headed drive self-locking motor). The output end of the eighth drive device is fixedly connected to the power wheel. The left and right sides of the movable plate 20 are both rotatably connected to the driven wheels. The power wheel and the driven wheel are both rollingly provided on the slide rails 22. When the eighth drive device is started, the output shaft of the eighth drive device can drive the power wheel to rotate, thereby causing the movable plate 20 to move along the slide rails 22.

[0058] The bottom of the fixed shell 4 is fixedly provided with support legs 21, which are arranged on the ground. The support legs 21 provide support force for the fixed shell 4 so that the side mold 1 can be stable and firm when moving.

[0059] In order to facilitate the flipping of the third drive mechanism 9, in this embodiment, two symmetrically arranged double-headed connecting members 8 are respectively provided on the front and rear sides of the end mold 3, and a third drive mechanism 9 is provided on the double-headed connecting member 8. The third drive mechanism 9 can adjust the position of the double-headed connecting member 8. After the end mold 3 is installed or disassembled, the second drive device 10 can be driven to start, so that the third drive mechanism 9 and the double-headed connecting member 8 swing.

[0060] The third driving mechanism 9 is rotatably arranged on the outer surface of the fixed housing 4 . A second driving device 10 is arranged in the fixed housing 4 and can drive the third driving mechanism 9 to rotate, so as to drive the third driving mechanism 9 to flip.

[0061] The double-headed connecting member 8 includes a rotating block 801 and an electromagnet 802. There are two electromagnets 802, which are spaced apart from each other. When the double-headed connecting member 8 is located at the front and rear ends of the side mold 1, the power is turned on or off to control the adsorption or release of the end mold 3. Specifically, when current passes through the coil of the electromagnet 802, the electrons in the wire begin to flow under the action of the electric field, and the flowing electrons generate a magnetic field around the wire; this magnetic field intersects with the space in which the wire is located to form a circular magnetic field coil, which is the magnetic field of the electromagnet 802 (if an iron core is inserted into the electromagnet 802, the iron core will be magnetized by the magnetic field of the energized solenoid, and the magnetized iron core will also become a magnet. The two magnetic fields are superimposed on each other, thereby greatly enhancing the magnetism of the electromagnet 802. At the same time, by changing the size and direction of the current, the size and direction of the magnetic field of the electromagnet 802 can be changed), thereby controlling the adsorption and release of the magnetic block.

[0062] The rotating block 801 is fixedly connected to the movable end of the eighth telescopic device 902, and the front and rear sides of the rotating block 801 are fixedly connected to the electromagnet 802. Two magnetic blocks spaced apart on the left and right sides are fixedly provided on the opposite sides of the two end molds 3. The electromagnet 802 and the magnetic blocks are attracted to each other. The electromagnet 802 and the magnetic blocks cooperate with each other to connect the rotating block 801 with the end mold 3. When the electromagnet 802 is energized, it can adsorb the magnetic blocks. When the electromagnet 802 is de-energized, it can release the magnetic blocks to facilitate the installation and disassembly of the end mold 3. There is no need to manually fix them with bolts one by one, which greatly reduces the labor intensity of the workers.

[0063] The position of the double-head connecting member 8 can be adjusted through the third driving mechanism 9 so that the end mold 3 can be better installed and disassembled. Specifically, the third driving mechanism 9 includes a first telescopic device 901 (the first telescopic device 901 is a first hydraulic telescopic rod) and an eighth telescopic device 902 (the eighth telescopic device 902 is a second hydraulic telescopic rod). The eighth telescopic device 902 is extended in the left and right directions.

[0064] The end face of the movable rod of the first telescopic device 901 is fixedly connected to the fixed rod of the eighth telescopic device 902. When the two side molds 1 move in relative or opposite directions, the eighth telescopic device 902 can be started to telescope, so that when the spacing between the two side molds 1 changes, the spacing between the two double-headed connecting members 8 can also change accordingly, avoiding the situation where the double-headed connecting member 8 is stuck when the side mold 1 moves. The end face of the movable rod of the eighth telescopic device 902 is transmission-connected with the double-headed connecting member 8, driving the first telescopic device 901 to start, so that the movable rod of the first telescopic device 901 can drive the eighth telescopic device 902 and the double-headed connecting member 8 to move during the extension process, so as to adjust the position of the double-headed connecting member 8 so that there will be no collision or jamming when installing or disassembling the end mold 3 and rotating the double-headed connecting member 8, thereby achieving the purpose of easy operation.

[0065] When the eighth telescopic device 902 moves, it can drive the double-headed connecting member 8 to move. When the double-headed connecting member 8 or the end mold 3 is extended to a point where there is no collision, it stops. Then, when the end mold 3 is in a vertical state, the first telescopic device 901 is controlled to contract so that the end mold 3 is inserted between the two side molds 1.

[0066] Through the setting of the second drive device 10, the rotation angle of the third drive mechanism 9 can be adjusted so that the third drive mechanism 9 can remove the end mold 3 without the need for manual installation and disassembly, thereby improving the utilization rate. Specifically, after the second drive device 10 is started, it can drive the rectangular block 1002 to rotate. When the rectangular block 1002 rotates, it can drive the first telescopic device 901 to rotate, thereby driving the double-headed connecting member 8 to swing.

[0067] Through the setting of the pressure sensor 13, when the end mold 3 is installed, the pressure sensor 13 will be squeezed, so that the pressure sensor 13 sends a signal to the limiting mechanism 11 after detecting the end mold 3, so that the limiting mechanism 11 is activated, and the end mold 3 is fixedly connected with the side mold 1 and the bottom mold 2. Specifically, the pressure sensors 13 are fixed on the opposite sides of the two side molds 1, and the pressure sensors 13 can be squeezed when the end mold 3 is inserted.

[0068] The limiting mechanism 11 is electrically connected to the pressure sensor 13 .

[0069] After the end mold 3 is installed, the pressure sensor 13 detects the start signal, which can enable the third drive device 1103. After the third drive device 1103 is started, it can drive the round rod 1101 to rotate, and then the lead screw 1203 rotates. When the lead screw 1203 rotates, it can drive the clamping sleeve 1204 to move along the limiting hole and be inserted into the slots of the side mold 1, the bottom mold 2 and the inner mold 23, so as to improve the connection stability between the end mold 3 and the side mold 1, the bottom mold 2 and the inner mold 23, thereby making it firm and durable. Specifically, a cavity 15 is provided inside the end mold 3, and a plurality of fixing seats 16 are fixed on the inner side wall of the cavity 15. The fixing seats 16 can support the round rod 1101.

[0070] The limiting mechanism 11 includes a round rod 1101 , a universal joint 1102 and a third driving device 1103 (the third driving device 1103 is a third driving self-locking motor). There are multiple round rods 1101 and universal joints 1102 .

[0071] The round rods 1101 are all rotatably inserted on the fixing seat 16, and adjacent round rods 1101 are connected to each other through universal joints 1102. Since adjacent round rods 1101 are connected to each other through universal joints 1102, when one round rod 1101 rotates, it can drive other round rods 1101 to rotate.

[0072] The third driving device 1103 is fixed on the inner wall of the cavity 15, and the output shaft of the third driving device 1103 is fixed with a lower gear 18. An upper gear 19 is fixed on one of the round rods 1101, and the upper gear 19 and the lower gear 18 are engaged with each other. When the pressure sensor 13 sends a signal to drive the third driving device 1103 to start, the third driving device 1103 can drive the lower gear 18 to rotate after starting. Since the upper gear 19 and the lower gear 18 are engaged with each other, the upper gear 19 can be driven to rotate, and when the upper gear 19 rotates, it can drive the round rod 1101 to rotate.

[0073] The plug-in assembly 12 is sleeved on the round rod 1101, and the third driving device 1103 is used to drive the round rod 1101 to rotate. When the round rod 1101 rotates, it can drive the plug-in assembly 12 to rotate, thereby realizing the connection between the end mold 3 and the side mold 1, the bottom mold 2 and the inner mold 23 through the plug-in assembly 12.

[0074] The plug-in assembly 12 includes a first bevel gear 1201, a second bevel gear 1202, a lead screw 1203 and a clamping sleeve 1204. A plurality of limit bars are fixedly provided on the outer side of the clamping sleeve 1204. When the round rod 1101 rotates, it can drive the first bevel gear 1201 to rotate.

[0075] A plurality of support seats are fixedly provided in the cavity 15 , and the lead screw 1203 is rotatably inserted into the support seats. The lead screw 1203 is fixedly connected to the second bevel gear 1202 . The support seats can support the lead screw 1203 to prevent the lead screw 1203 from tilting or shaking.

[0076] The first bevel gear 1201 is fixedly sleeved on the round rod 1101 , and the first bevel gear 1201 and the second bevel gear 1202 are engaged with each other. Since the first bevel gear 1201 and the second bevel gear 1202 are engaged with each other, the second bevel gear 1202 can be driven to rotate.

[0077] A plurality of transparent limiting holes are provided on the end mold 3, and the clamping sleeve 1204 is sleeved on the lead screw 1203 and is threadedly connected to the lead screw 1203. The clamping sleeve 1204 is slidably inserted in the limiting hole. When the second bevel gear 1202 rotates, it can drive the lead screw 1203 to rotate, and when the lead screw 1203 rotates, it can drive the clamping sleeve 1204 to move along the limiting hole, so that the clamping sleeve 1204 is inserted into the slot to connect the end mold 3 and the side mold 1.

[0078] Slots with openings facing the end mold 3 are provided on the side mold 1 , the bottom mold 2 and the inner mold 23 , and the clamping sleeve 1204 passes through the limiting hole and is slidably inserted into the slots.

[0079] A limiting mechanism 11 is provided in the end mold 3, and a plurality of plug-in components 12 are provided on the limiting mechanism 11. When the end mold 3 is inserted into the gap, the limiting mechanism 11 can drive the plug-in components 12 to be inserted into the side mold 1, the bottom mold 2 and the inner mold 23 respectively. The limiting mechanism 11 and the plug-in components 12 cooperate with each other to connect the end mold 3 with the side mold 1, the bottom mold 2 and the inner mold 23.

[0080] Working principle: The specific operation is as follows: S1, under the action of the second driving mechanism, the movable plate 20 carrying the steel bar frame can be moved along the slide rail 22 to the gap between the two side molds 1, and stops when the bottom mold 2 is flush with the side mold 1 (the second driving mechanism includes an eighth driving device, a power wheel and a driven wheel. A chamber is provided inside the movable plate 20, and an eighth driving device is fixedly installed in the chamber (the eighth driving device is an eighth double-headed drive self-locking motor). The output end of the eighth driving device is fixedly connected to the power wheel, and the left and right sides of the movable plate 20 are both rotatably connected to the driven wheel. The power wheel and the driven wheel are both rollingly arranged on the slide rail 22. When the eighth driving device is started, the output shaft of the eighth driving device can drive the power wheel to rotate, thereby moving the movable plate 20 along the slide rail 22);

[0081] S2, through the first driving mechanism, the two side molds 1 are moved in opposite directions within the fixed shell 4, and stop when the opposite sides of the two side molds 1 abut against the left and right sides of the bottom mold 2. At the same time, when the two side molds 1 retract inward, the eighth telescopic device 902 is also activated, so that the double-headed connecting member 8 and the end mold 3 maintain synchronous movement (the first driving mechanism includes a seventh hydraulic telescopic rod and a seventh slide rail, the seventh hydraulic telescopic rod is fixed to the inner side wall of the fixed shell 4, the movable rod end face of the seventh hydraulic telescopic rod is hingedly connected to the side mold 1, the seventh slide rail is fixed to the inner bottom wall of the fixed shell 4, and the side mold 1 is slidably provided on the seventh slide rail.
