Description

Technical Field

[0001] This invention relates to an auxiliary locator, and more particularly to an auxiliary locator for beam and slab installation. Background Technology

[0002] During construction, a formwork needs to be laid at the bottom of the roof beams and slabs, requiring its positioning, for example:

[0003] Patent publication number CN114109036A discloses an auxiliary installation device and a method for installing concrete beam and slab formwork. The device includes: a beam formwork comprising two side formworks arranged opposite each other and a bottom formwork connected to one end of the two side formworks; the auxiliary installation device for the concrete beam and slab formwork includes: a support beam, a moving platform, and a movable arm; the movable arm has a pressing section, a prying section, and a middle section; the middle section is connected between the pressing section and the prying section and is hinged to the moving platform; the pressing section is arranged opposite to the fixed arm; after the prying section is moved, the pressing section flips and presses against the inside of the other side formwork to lock the auxiliary installation device onto the beam formwork.

[0004] The installation of this beam and slab formwork auxiliary device requires manual lifting of the beam and slab upwards. When it reaches the top of the floor, the beam and slab cannot be installed due to the height limitation of the person, and the beam and slab positioning effect cannot be achieved. Therefore, an auxiliary positioning device for beam and slab installation at high altitudes was developed. Summary of the Invention

[0005] In order to overcome the shortcomings of existing devices that cannot position beams and slabs at high altitudes, the purpose of this invention is to provide an auxiliary positioning device for beam and slab installation at high altitudes.

[0006] The technical solution is as follows: An auxiliary positioning device for beam and slab installation includes a push frame, a lifting frame, a sliding frame, a support guide frame, a placement plate, a drive motor, a winding wheel, a steel wire rope, a lifting mechanism, and a clamping mechanism. The push frame is connected to the lifting frame on both the front and rear sides of the upper right side. The lifting frames are slidably connected to each other. The support guide frame is slidably connected to the left side of the sliding frame. The lifting frame and the sliding frame are slidably connected. The placement plate is connected to the support guide frame. The drive motor is connected to the upper right side of the push frame and is located on the right side of the lifting frame. The output shaft of the drive motor is connected to the winding wheel, and a steel wire rope is wound on the winding wheel. The left side of the steel wire rope is connected to the support guide frame. The sliding frame is equipped with a lifting mechanism, and the placement plate is equipped with a clamping mechanism.

[0007] As an improvement to the above solution, the lifting mechanism includes a lifting motor, a lead screw, a transmission assembly, a threaded connecting sleeve, a drive switch, and a start / stop switch. The lifting motor is connected to the upper right front side of the push frame, and is located on the right side of the front lifting frame. The lifting motor is also located in front of the drive motor. A lead screw is connected to the output shaft of the lifting motor. The upper part of the lead screw is rotatably connected to the front lifting frame, and the rear lifting frame is also rotatably connected to a lead screw. A transmission assembly is connected between the upper parts of the two lead screws. Threaded connecting sleeves are threadedly connected to the lead screws. The threaded connecting sleeves are fixedly connected to the right side of the sliding frame. A drive switch is connected to the left front part of the sliding frame. The drive switch and the lifting motor are electrically connected. A start / stop switch is connected to the left side of the placement plate. The start / stop switch and the lifting motor are electrically connected.

[0008] As an improvement to the above solution, the clamping mechanism includes clamping rods, positioning rods, clamping springs, and U-shaped connecting rods. Four rectangular slots are opened on the placement plate, and clamping rods are slidably connected in each rectangular slot. The top of each clamping rod on the left side is connected to a positioning rod. The upper left part of each positioning rod is an inclined surface. Clamping springs are connected between the side of the clamping rods that are far apart from each other and the rectangular slots. A U-shaped connecting rod is connected between the two front clamping rods, and a U-shaped connecting rod is also connected between the two rear clamping rods.

[0009] As an improvement to the above solution, a blocking mechanism is also included. The blocking mechanism includes a baffle and a blocking spring. The baffle is slidably connected to the upper right side of the placement plate, and two blocking springs are connected between the baffle and the placement plate.

[0010] As an improvement to the above solution, a limiting mechanism is also included. The limiting mechanism includes a guide plate, ratchet, blocking blocks, push springs, magnetic levers, and pull springs. The bottom of the placement plate is connected to the guide plate, and four ratchets are connected to the guide plate. Blocks are connected to the clamping rods, and the blocking blocks are slidably connected to the guide plate. Push springs are connected between the side of the blocking blocks that is far apart from each other and the guide plate. Magnetic levers are slidably connected to the blocking blocks, and the magnetic levers are locked onto the ratchets. Pull springs are connected between the blocking blocks and the magnetic levers.

[0011] As an improvement to the above solution, a return mechanism is also included. The return mechanism includes a start switch and an electromagnet. The start switch is connected to the middle of the bottom of the push frame, and the electromagnet is connected to the bottom of the guide plate. The start switch and the electromagnet are electrically connected.

[0012] As an improvement to the above solution, an adsorption mechanism is also included. The adsorption mechanism includes a contact switch and an electric suction cup. The contact switch is connected to the top left side of the push frame, and the electric suction cup is connected between the placement plates. Suction holes are opened on the left and right sides of the middle of the placement plate, and the suction holes are located directly above the electric suction cup. The contact switch and the electric suction cup are electrically connected.

[0013] As an improvement to the above solution, four wheels are installed at the bottom of the pusher frame.

[0014] The present invention has the following advantages: 1. The present invention drives the lead screw to rotate counterclockwise by rotating the lifting motor counterclockwise. The rotation of the lead screw drives the threaded connecting sleeve to move upward. The upward movement of the threaded connecting sleeve drives the support guide frame and the placement plate to move upward, thereby enabling the installation of beams and plates even at very high heights.

[0015] 2. In this invention, the inclined surface of the positioning rod drives the beam plate to press downward, thereby moving the clamping rod to the side away from each other, compressing the clamping spring, and clamping the beam plate under the action of elastic force, thus fixing the beam plate.

[0016] 3. The present invention uses a baffle to prevent the beam from moving further to the right, thereby better fixing the beam on the placement plate.

[0017] 4. In this invention, the magnetic clamp moves left and right by sliding the blocking block, and the magnetic clamp intermittently engages with the ratchet, thereby slowing down the installation speed of the beam and plate and thus better fixing the beam and plate.

[0018] 5. This invention activates the electromagnet by starting a switch, thereby causing the magnetic lever to move downwards and no longer jam the ratchet, thus resetting the blocking block and clamping rod.

[0019] 6. This invention activates the electric suction cup by turning on the contact switch, thereby causing the beam to adhere to the placement plate, thus achieving a fixing effect. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] An auxiliary positioning device for beam and slab installation, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the assembly includes a push frame 1, a lifting frame 2, a sliding frame 3, a support guide frame 31, a placement plate 4, a drive motor 5, a winding wheel 6, a wire rope 7, a lifting mechanism 8, and a clamping mechanism 9. The push frame 1 has four wheels at its bottom for easier and less strenuous transport of beams. The upper right and front / rear sides of the push frame 1 are connected to the lifting frame 2. The sliding frame 3 is slidably connected between the lifting frames 2. The support guide frame 31 is slidably connected to the left side of the sliding frame 3. The lifting frame 2 and the support guide frame 31 are slidably connected. The placement plate 4 is connected to the support guide frame 31. A drive motor 5 is connected to the upper right part, and the drive motor 5 is located on the right side of the lifting frame 2. A winding wheel 6 is connected to the output shaft of the drive motor 5, and a steel wire rope 7 is wound on the winding wheel 6. The left side of the steel wire rope 7 is connected to the support guide frame 31. When the drive motor 5 is started, the output shaft of the drive motor 5 will drive the winding wheel 6 to rotate, thereby tightening the steel wire rope 7 and driving the support guide frame 31 to move upward. The sliding frame 3 is provided with a lifting mechanism 8, which can make the support guide frame 31 move upward. The placement plate 4 is provided with a clamping mechanism 9, which can clamp and fix the beam plate.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the lifting mechanism 8 includes a lifting motor 81, a lead screw 82, a transmission assembly 83, a threaded connecting sleeve 84, a drive switch 85, and a start / stop switch 86. The lifting motor 81 is connected to the upper right front side of the push frame 1. The lifting motor 81 is located on the right side of the front lifting frame 2 and is also located in front of the drive motor 5. The lead screw 82 is connected to the output shaft of the lifting motor 81. The upper part of the lead screw 82 is rotatably connected to the front lifting frame 2, and the rear lifting frame 2 is also rotatably connected to the lead screw 82. The transmission assembly 83 is connected between the upper parts of the two lead screws 82. Each lead screw 82 is threadedly connected to a threaded connecting sleeve 84. The threaded connecting sleeve 84 is fixedly connected to the right side of the sliding frame 3. A drive switch 85 is connected to the front left side of the sliding frame 3. The drive switch 85 is electrically connected to the lifting motor 81. A start / stop switch 86 is connected to the left side of the placement plate 4. The start / stop switch 86 is electrically connected to the lifting motor 81. When the drive switch 85 is turned on, it will drive the lifting motor 81 to work, causing the lead screw 82 to rotate and thus causing the threaded connecting sleeve 84 to move upward. The threaded connecting sleeve 84 will then drive the support guide frame 31 and the placement plate 4 to move upward.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the clamping mechanism 9 includes clamping rods 91, positioning rods 92, clamping springs 93, and U-shaped connecting rods 94. The placement plate 4 has four rectangular slots, and clamping rods 91 are slidably connected in each rectangular slot. The top of each clamping rod 91 on the left side is connected to a positioning rod 92. The upper left part of the positioning rod 92 is an inclined surface. A clamping spring 93 is connected between the side of the clamping rods 91 that is far apart from each other and the rectangular slot. A U-shaped connecting rod 94 is connected between the two front clamping rods 91 and the two rear clamping rods 91. The movement of the positioning rod 92 to the side that is far apart from each other will cause the left clamping rod 91 to move to the side that is far apart from each other. Under the action of the U-shaped connecting rod 94, the right clamping rod 91 will also move to the side that is far apart from each other.

[0039] When building a house, beams and slabs need to be fixed, and positioning is required during fixing. This auxiliary positioning device can be used for this purpose. First, place the auxiliary positioning device in the area where positioning is needed. Then, place the beam and slab on the placement plate 4. First, place the beam and slab on the inclined surface of the upper left of the positioning rod 92, causing the positioning rod 92 to move away from each other. This moves the left clamping rod 91 away from each other, and under the action of the U-shaped connecting rod 94, it also moves the right clamping rod 91 away from each other. This allows the clamping rod 91 to automatically unfold, making it easier to place the beam and slab in the middle of the placement plate 4. At this point, it is compressed, and also under the elastic force of the clamping spring 93... Clamping rod 91 clamps and fixes the beam for installation and positioning during upward transport. After the beam is placed, drive motor 5 can be started. The clockwise rotation of drive motor 5 drives winding wheel 6 to rotate, which in turn tightens wire rope 7. The tightening of wire rope 7 causes support guide frame 31 to slide upward on the guide rail of sliding frame 3. The upward movement of support guide frame 31 causes placement plate 4 to move upward. When placement plate 4 is lifted to the top of sliding frame 3, before reaching the required position of beam, placement plate 4 will touch drive switch 85 on sliding frame 3. Drive switch 85 will then activate lifting motor 81, which will then begin working. The counterclockwise rotation of the rotating shaft drives the front lead screw 82 to rotate, which in turn drives the rear lead screw 82 to rotate under the action of the transmission group 83. This causes the threaded connecting sleeve 84 to move upward. The upward movement of the threaded connecting sleeve 84 then drives the sliding frame 3 to move upward, which in turn drives the support guide frame 31 and the placement plate 4 to move upward. When they reach the appropriate height, the start / stop switch 86 on the placement plate 4 will touch the floor slab. At this time, the lifting motor 81 will turn off, and the worker can then position the beam. After positioning, the lifting motor 81 can be turned on again, allowing it to rotate counterclockwise. The counterclockwise rotation of the lifting motor 81 will drive the lead screw 82 to rotate counterclockwise, and then the threaded connecting sleeve 84 will move upward. The threaded connecting sleeve 84 will move downwards, thereby causing the support guide frame 31 and the placement plate 4 to move downwards to the top of the sliding frame 3. At this time, the drive motor 5 is turned off, and the support guide frame 31 and the placement plate 4 will move downwards due to their own gravity, which will drive the winding wheel 6 to rotate and loosen the wire rope 7, thereby causing the support guide frame 31 and the placement plate 4 to move back to their original positions. In summary, when transporting the beam plate upwards, the lifting mechanism 8 can drive the lead screw 82 to rotate through the lifting motor 81, thereby causing the threaded connecting sleeve 84 to move upwards. The upward movement of the threaded connecting sleeve 84 will drive the sliding frame 3 to move upwards, and the upward movement of the sliding frame 3 will drive the support guide frame 31 and the placement plate 4 to move upwards, thereby transporting the beam plate to a suitable height for splicing.

[0040] Example 2

[0041] Based on Example 1, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a blocking mechanism 10, which includes a baffle 101 and a blocking spring 102. The baffle 101 is slidably connected to the upper right side of the placement plate 4. Two blocking springs 102 are connected between the baffle 101 and the placement plate 4. The baffle 101 will move up and down on the placement plate 4.

[0042] When the beam is placed, there is a baffle 101 on the right side of the placement plate 4. When the right side of the beam is pressed against the baffle 101, the baffle 101 and the beam are squeezed together, which will prevent the beam from moving to the right. At this time, the blocking spring 102 will be compressed. After the beam is installed, the beam no longer squeezes the baffle 101, and the blocking spring 102 will return to its original position.

[0043] like Figure 3 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 13 As shown, it also includes a limiting mechanism 11, which includes a guide plate 1101, ratchet 1102, blocking block 1103, push spring 1104, magnetic latch 1105, and pull spring 1106. The bottom of the placement plate 4 is connected to the guide plate 1101, and four ratchet 1102 are connected to the guide plate 1101. Blocks 1103 are connected to the clamping rod 91, and the blocking blocks 1103 are slidably connected to the guide plate 1101. Push springs 1104 are connected between the two sides that are far apart and the guide plate 1101. Magnetic levers 1105 are slidably connected to the blocking blocks 1103. The magnetic levers 1105 are locked on the ratchet 1102. Pull springs 1106 are connected between the blocking blocks 1103 and the magnetic levers 1105. When the blocking blocks 1103 move, they will drive the magnetic levers 1105 to move. The magnetic levers 1105 will lock on the ratchet 1102, limiting the position of the clamping rod 91.

[0044] When placing the beam, the beam is first placed on the positioning rod 92. Due to its tilt angle, it moves downwards, causing the left clamping rod 91 to move away from each other. Under the action of the U-shaped connecting rod 94, the right clamping rod 91 moves away from each other. When the front clamping rod 91 moves forward and the rear clamping rod 91 moves backward, the front blocking block 1103 also slides forward, and the rear blocking block 1103 also slides backward. At this time, the push spring 1104 is stretched. During the movement of the blocking block 1103, the magnetic locking rod 1105 also moves. When the magnetic locking rod 1105 contacts the protruding position of the adjacent ratchet 1102, the magnetic locking rod 1105 will lock onto the ratchet 1102. The pull spring 1106 is stretched. When the magnetic locking rod 1105 separates from the protruding position of the ratchet 1102, the pull spring 1106 will cause the magnetic locking rod 1105 to lock onto the ratchet 1102. On 102, repeat the above operation. When the clamping rod 91 moves back and forth, it works in conjunction with the ratchet 1102 and the magnetic latch 1105. This causes the magnetic latch 1105 to intermittently engage with the ratchet 1102, thereby achieving a deceleration effect. This prevents the clamping rod 91 from moving too fast, which could lead to poor fixing of the beam plate. After the beam plate is installed, the magnetic latch 1105 engages with the ratchet 1102, ensuring that the clamping rod 91 remains fixed to the beam plate. After the beam plate is fixed, if it is necessary to reset the clamping rod 91, simply move the magnetic latch 1105 downwards to stretch the pull spring 1106. After the magnetic latch 1105 moves downwards and separates from the ratchet 1102, the clamping rod 91 and the blocking block 1103 will be reset under the action of the pushing spring 1104. Release the magnetic latch 1105, and the magnetic latch 1105 will be reset under the action of the pull spring 1106 and re-lock onto the ratchet 1102.

[0045] like Figure 3 , Figure 11 , Figure 12 and Figure 13 As shown, it also includes a return mechanism 12, which includes a start switch 1201 and an electromagnet 1202. The start switch 1201 is connected to the top center of the push frame 1, and the electromagnet 1202 is connected to the bottom of the guide plate 1101. The start switch 1201 and the electromagnet 1202 are electrically connected.

[0046] When the beam needs to be removed, the start switch 1201 needs to be turned on. The start switch 1201 will control the electromagnet 1202, and the electromagnet 1202 will start working. The electromagnet 1202 will attract the magnetic lever 1105 downward. At this time, the pull spring 1106 is stretched, and the magnetic lever 1105 is no longer stuck on the ratchet 1102. This causes the front blocking block 1103 and the front clamping rod 91 to move backward and reset, and the rear blocking block 1103 and the rear clamping rod 91 to move forward and reset. When the start switch 1201 is turned off, the electromagnet 1202 will stop working and lose its magnetism. The magnetic lever 1105 will move downward and reset under the action of the pull spring 1106, and will be stuck on the ratchet 1102 again.

[0047] like Figure 3 and Figure 13 As shown, it also includes an adsorption mechanism 13, which includes a contact switch 1301 and an electric suction cup 1302. The contact switch 1301 is connected to the top left side of the push frame 1, and the electric suction cup 1302 is connected between the placement plates 4. Suction holes are opened on the left and right sides of the middle of the placement plate 4, and the suction holes are located directly above the electric suction cup 1302. The contact switch 1301 and the electric suction cup 1302 are electrically connected.

[0048] When the beam is secured, there may be a gap between the beam and the placement plate 4. Activating the contact switch 1301 sends an electrical signal to the electric suction cup 1302, which then firmly attaches the beam to the placement plate 4. To remove the beam, simply turn off the contact switch 1301; the electric suction cup 1302 will then stop working, allowing the beam to be removed.

[0049] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
