[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Please see attached Figure 1 and attached Figure 2A waffle cone splicing fixture comprises a mounting plate assembly 10 and a self-locking clamping mechanism 11; the mounting plate assembly 10 comprises a mounting box 12, a mounting plate body 13 and a limiting slide assembly; the mounting box 12 is arranged at the center of the top surface of the mounting plate body 13, and the limiting slide assembly is installed on the bottom surface of the mounting plate body 13; the self-locking clamping mechanism 11 comprises an inner support assembly and a driving assembly, the driving assembly is installed in the mounting box 12 and passes through the mounting plate body 13, the inner support assembly is connected between the driving assembly and the limiting slide assembly, so that the end of the inner support assembly is movably arranged below the mounting plate body 13 along the limiting slide assembly through the driving assembly and can be clamped on the wall of the waffle cone.

[0043] The driving assembly is used to drive the inner support assembly to move, so that the end of the inner support assembly can be pressed against the inner wall of the waffle cone, thereby playing a role of stable clamping, and the waffle cone is not easy to fall off. The limiting slide is used to guide and limit the movement of the inner support assembly, which is conducive to improving the movement stability and controllability of the inner support assembly.

[0044] Preferably, the mounting plate body 13 can be a disc-shaped structure close to the size of the waffle cone, which is convenient for installing the mounting box 12, the limit slide assembly and the self-locking clamping mechanism 11. When in use, the mounting plate body 13 is covered on the top of the waffle cone, so that the end of the inner support assembly is inserted into the inside of the waffle cone, so that the end of the inner support assembly can be driven by the driving assembly to press against the inner wall of the waffle cone.

[0045] Please see attached Figure 2 and attached Figure 3 The limiting slide assembly includes a plurality of limiting slides, and the plurality of limiting slides are long strip structures with an inverted U-shaped cross-section. The inner support assembly includes a plurality of inner support rods, and the middle parts of the plurality of inner support rods can be slidably embedded in the plurality of limiting slides; one end of the plurality of inner support rods is movably connected to the driving assembly, and the other end of the plurality of inner support rods can be clamped on the wall of the waffle tube.

[0046] Preferably, three limit slides can be provided, namely a first limit slide 14, a second limit slide 15 and a third limit slide 16. The length directions of the first limit slide 14, the second limit slide 15 and the third limit slide 16 are arranged along the radial direction of the mounting disk body 13 and are evenly distributed on the bottom surface of the mounting disk body 13.

[0047] Correspondingly, three inner support rods can be provided, namely, the first inner support rod 22, the second inner support rod 23 and the third inner support rod 24. The first inner support rod 22 is provided corresponding to the first limit slide 14, the second inner support rod 23 is provided corresponding to the second limit slide 15, and the third inner support rod 24 is provided corresponding to the third limit slide 16. The three inner support rods can be positioned and pressed against the inner wall of the waffle tube at three points, thereby ensuring the clamping stability of the waffle tube, and can adapt to cylindrical waffle tubes of different sizes, and are not easy to fall off during the process of lifting, etc., ensuring construction safety.

[0048] Please see attached Figure 3 The driving assembly includes a connecting clamp 17, a worm 18, a worm wheel 19, a rotating column 20 and a rotating disk 21; the connecting clamp 17 is installed on the side wall of the installation box 12, and one end of the connecting clamp 17 located in the installation box 12 is coaxially fixedly connected to the worm 18; the worm wheel 19 is coaxially fixedly connected to the rotating column 20 and meshingly connected with the worm 18. The upper end of the rotating column 20 is rotatably installed in the installation box 12 through a rotating bearing, and the lower end of the rotating column 20 passes through the through hole reserved in the center of the installation disk body 13 and is coaxially fixedly connected to the center of the rotating disk 21.

[0049] Preferably, the connection clamp 17 can be cylindrical, hexagonal, or other structures, so that it is easy to connect and drive the connection clamp 17 to rotate through an external drive tool such as a motor, and can control the connection clamp 17 to rotate forward or backward at a uniform speed. The shape, material, and size of the connection clamp 17 can be adaptively adjusted according to the connection requirements of the external drive tool.

[0050] The worm 18 rotates synchronously with the connecting clamp 17 , and the worm 18 rotates while the meshing transmission worm wheel 19 rotates, thereby driving the rotating disk 21 to rotate through the worm wheel 19 , and then using the rotating rotating disk 21 to drive the three inner support rods to move synchronously.

[0051] Please see attached Figure 3 and attached Figure 4 The rotating disk 21 includes a rotating disk body 25, and the lower end of the rotating column 20 is coaxially fixedly connected to the rotating disk body 25; a plurality of arc-shaped guide grooves are formed on the rotating disk body 25 at intervals, and one end of a plurality of inner support rods can be slidably embedded in the plurality of arc-shaped guide grooves respectively; the ends of the plurality of arc-shaped guide grooves close to the center of the rotating disk body 25 are located on the same circumference, and the ends of the plurality of arc-shaped guide grooves away from the center of the rotating disk body 25 are also located on the same circumference.

[0052] Preferably, three arc-shaped guide grooves can be provided, namely, a first arc-shaped guide groove 26, a second arc-shaped guide groove 27 and a third arc-shaped guide groove 28. The first inner support rod 22 is provided in cooperation with the first arc-shaped guide groove 26, the second inner support rod 23 is provided in cooperation with the second arc-shaped guide groove 27, and the third inner support rod 24 is provided in cooperation with the third arc-shaped guide groove 28. The two circumferences at both ends of the plurality of arc-shaped guide grooves are concentric with the rotating disk body 25.

[0053] When the rotating column 20 rotates, the rotating disk body 25 is driven to rotate synchronously. By setting the arc guide groove, the arc guide groove extends in an arc shape from a position close to the center of the rotating disk body 25 to a position close to the edge of the rotating disk body 25, so that when the rotating disk body 25 rotates, each inner support rod can be pushed to move synchronously, and the rotation of the rotating disk body 25 is converted into a linear motion of the inner support rod along the length direction of the limiting slide under the linear limit of the limiting slide.

[0054] The numbers of the inner support rods, arc-shaped guide grooves and limit slides are consistent and arranged one by one, and their numbers can be adaptively increased according to actual clamping requirements such as the size and weight of the waffle cone.

[0055] Please see attached Figure 5 The inner support rod includes a limiting slide arm 29 and an inner support plate 32; one end of the limiting slide arm 29 is slidably embedded in the arc guide groove, the middle part of the limiting slide arm 29 is slidably embedded in the limiting slide seat, and the other end of the limiting slide arm 29 is connected to one end of the support plate 32; the other ends of the support plates 32 of several inner support rods jointly clamp the waffle cone.

[0056] Preferably, the limit slide arm 29 and the inner support plate 32 are vertically connected to form an L-shaped structure. The limit slide arm 29 is used to cooperate with the limit slide seat and the arc-shaped guide groove to ensure the linear movement of the inner support rod. The inner support plate 32 slides synchronously with the limit slide arm 29. When the inner support plate 32 slides toward the inner wall of the waffle tube, the three inner support plates 32 can press against the waffle tube, thereby ensuring reliable clamping of the waffle tube. When the inner support plate 32 slides away from the inner wall of the waffle tube, the clamping of the waffle tube can be released.

[0057] Preferably, the worm 18 and the worm wheel 19 can adopt the worm and gear assembly of the prior art, which has a self-locking function of the latch teeth, can realize the transmission of force when the connecting clamp 17 inputs the driving force, and realize self-locking through the engagement of the latch teeth when the connecting clamp 17 stops inputting the driving force, so as to ensure the relative stillness of the worm 18 and the worm wheel 19, thereby ensuring that the inner support plate 32 presses against the inner wall of the waffle tube. Even in the event of unexpected situations such as power failure and equipment failure, the self-locking function can be used to ensure that the three inner support plates 32 effectively press and clamp the waffle tube.

[0058] Please see attached Figure 5A roller 31 is rotatably mounted on one end of the limiting sliding arm 29 through a connecting column 30 via a wheel axle, and the roller 31 is rollably arranged in the arc guide groove.

[0059] The roller 31 rolls in the arc-shaped guide groove, converting the sliding friction into rolling friction, reducing the friction resistance, thereby ensuring that the movement of the limit sliding arm 29 is smooth, stable, and free of jamming.

[0060] Please see attached Figure 5 The side of the support plate 32 facing the waffle cone is provided with an anti-skid rubber layer 33, so that the support plate 32 is pressed tightly against the wall of the waffle cone through the anti-skid rubber layer 33.

[0061] The provision of the anti-slip rubber layer 33 can increase the friction between the support plate 32 and the inner wall of the waffle cone, thereby improving the clamping stability of the waffle cone. At the same time, the rubber material can play a certain buffering effect through deformation, which can reduce the damage to the waffle cone caused by impact, friction, etc. while ensuring the clamping stability.

[0062] Please see attached Figure 1 To Attachment Figure 5 , a method for using a waffle cone splicing fixture, comprising the following steps:

[0063] Step 1: Place the waffle cone splicing fixture on the waffle cone, and make the inner support plate 32 of the inner support assembly be located inside the waffle cone.

[0064] Step 2: Use an external driving tool to drive the drive assembly to move.

[0065] The step 2 comprises the following sub-steps:

[0066] Step 2.1: Use an electric / manual external driving tool to match and connect and drive the connecting clamp 17 to rotate, so that the connecting clamp 17 drives the worm 18 to rotate synchronously.

[0067] Step 2.2: The worm 18 meshes with the worm wheel 19 to rotate, so that the worm wheel 19 drives the rotating column 20 to rotate.

[0068] Step 2.3: The rotating column 20 drives the rotating disk body 25 of the rotating disk 21 to rotate synchronously.

[0069] Step 3: The driving assembly drives the inner support assembly to move, so that the inner support assembly clamps the wall of the waffle cone.

[0070] The step 3 comprises the following sub-steps:

[0071] Step 3.1: During the rotation of the rotating disk 21 , the arc-shaped guide groove moves relative to one end of the limiting sliding arm 29 .

[0072] Step 3.2: Under the guidance of the arc-shaped guide groove, the limiting sliding arm moves linearly along the U-shaped groove of the limiting sliding seat to move the inner support plate 32 toward the inner wall of the waffle tube.

[0073] Due to the arc structure of the arc guide groove, it is possible to provide motion guidance along the radial and circumferential directions of the rotating disk body 25, thereby converting the rotation of the rotating disk body 25 into the linear motion of the limiting slide 29. The rotating disk body 25 is coaxially arranged with the mounting disk 13, and the limiting slide is arranged along the radial direction of the mounting disk 13, thereby ensuring the radial motion of the limiting slide 29 along the rotating disk body 25, and further ensuring the motion synchronization and radiality of the three limiting slides 29.

[0074] Step 3.3: The inner support plate 32 is pressed against the inner wall of the waffle cone through the anti-slip rubber layer 33, so that the plurality of inner support rods clamp the waffle cone.

[0075] The inner support plates 32 of the three inner support rods are synchronously moved to the inner wall of the waffle cylinder and pressed against the inner wall of the waffle cylinder with a certain pressure to ensure stable clamping of the waffle cylinder.

[0076] Step 4: Clean the surface of the building formwork before hoisting the waffle tube and remove hard objects on the surface of the building formwork.

[0077] Step 5: Place wooden blocks on the surface of the building formwork, and use a hoist to lift the waffle tube fixed by the waffle tube splicing clamp to the surface of the building formwork and place it gently.

[0078] The lifting of the waffle cone is a conventional operation in this field, and its specific operation process will not be described in detail here.

[0079] Step 6: Workers should lift and put down the waffle cones gently when assisting in carrying them, and should not drag the waffle cones to avoid scratching the surface of the waffle cones.

[0080] Step 7: During the horizontal transportation of materials, lay a two-meter-wide plywood walkway above the pipe caps of the waffle cones. Material transportation personnel and other construction personnel should try to avoid stepping directly on the pipe caps to avoid damage or deformation of the waffle cones.

[0081] Step 8: Splice and install the waffle cones.

[0082] The splicing and installation of the waffle cone is a conventional operation in the art, and the specific splicing and installation process will not be described in detail here.

[0083] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention.
