Description

Technical Field

[0001] This invention relates to the field of construction engineering, and specifically to a climbing formwork system for construction engineering. Background Technology

[0002] During construction, workers often need to use climbing scaffolds when climbing at heights. A patent document with publication number CN216690329U discloses a climbing scaffold, including ladder legs. The upper end of each ladder leg has a circular groove, and the front end of each ladder leg has two rectangular grooves. A rectangular sliding groove is located at the rear end of the rectangular grooves on the ladder leg. This invention, through the use of a threaded rotating rod, a sliding block, and a flat gear meshing with the sliding block, allows workers to place necessary parts or tools on a shelf while using the climbing scaffold, providing a simple workbench and improving work efficiency. The rotating handle and sliding block ensure that the climbing scaffold can be adjusted to a parallel state regardless of its tilt angle, preventing parts or tools from falling, greatly improving practicality. However, the aforementioned climbing scaffold is not easy to disassemble, making it difficult to replace damaged parts promptly.

[0003] In the prior art, patent publication number CN218991042U describes a construction climbing scaffold. Addressing the problem that existing construction climbing scaffolds are inconvenient to disassemble and difficult to replace damaged components promptly, the following solution is proposed: It includes two ladder legs and multiple rectangular foot pedals. Each of the two ladder legs has multiple rectangular slots on one side. The other end of each rectangular foot pedal engages with two corresponding rectangular slots. Two connecting rods are located between the two ladder legs, and the multiple rectangular foot pedals are positioned between the two connecting rods. T-shaped blocks are fixedly installed at both ends of each connecting rod. Each of the two ladder legs has two T-shaped grooves, and each of the four T-shaped grooves has two openings. The T-shaped blocks engage with their corresponding T-shaped grooves. A locking mechanism is provided on each of the two connecting rods.

[0004] The above technical solution solves the problem of replacing the foot pedals, but it requires operating multiple locking mechanisms to unlock them, then separating the two ladder legs to remove all the foot pedals for replacement, and finally reinstalling all the foot pedals, which increases the complexity of the operation.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, a construction climbing formwork is provided that facilitates the disassembly and replacement of foot poles.

[0007] To achieve the above objectives, the present invention provides a building climbing scaffold for construction engineering, comprising a first mounting rod, a second mounting rod, a connecting rod, and a foot pedal. The first mounting rod and the second mounting rod are arranged opposite each other, and their opposite surfaces are provided with a first slot and a second slot for inserting the two ends of the foot pedal, respectively. The connecting rod is disposed at the upper and lower ends of the first mounting rod and the second mounting rod. The first end of the connecting rod is pulsatorically connected to a drive mechanism inside the first mounting rod and moves horizontally relative to the first mounting rod under the drive of the drive mechanism. The second end of the connecting rod is fixedly connected to the second mounting rod.

[0008] In some possible embodiments, a spring is installed in the second slot on the second mounting rod to apply an outward ejection force to the foot pedal inserted therein.

[0009] In some possible embodiments, the drive mechanism includes:

[0010] The transmission rod is rotatably mounted in the vertical space within the first mounting rod, and worm gears are coaxially connected to both ends of the transmission rod at positions corresponding to the connecting rod.

[0011] A threaded rod, the first end of which is coaxially connected to a worm gear that meshes with the worm wheel, and the second end of which passes through an opening on the first mounting rod and is threadedly connected to an internal threaded hole at the center of the first end of the connecting rod.

[0012] The first bevel tooth and the second bevel tooth mesh with each other, and the first bevel tooth is coaxially connected to the transmission rod;

[0013] A crank handle, the first end of which is coaxially connected to the second bevel gear and rotatably mounted on the first mounting rod, and the second end of which protrudes through an opening on the first mounting rod and forms an operating part.

[0014] In some possible embodiments, the first bevel tooth is located at the middle position of the drive rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the pedal lever is damaged and needs replacement, turn the crank handle. The crank handle then drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear then drives the transmission rod to rotate, which in turn drives the worm gear to rotate. The worm gear then drives the worm to rotate, which in turn drives the threaded rod to rotate. The threaded rod then drives the connecting rod to move outward. Because there are connecting rods at both the top and bottom, the second mounting rod moves to the right as a whole. When the pedal lever is about to disengage from the first slot but has not yet disengaged, push the damaged pedal lever towards the second mounting rod. The pedal lever overcomes the spring force and moves into the second slot. The first end of the pedal lever disengages from the first slot. Then, rotate the pedal lever at a certain angle to pull the second end out of the second slot, completing the disassembly. Repeat the above process in reverse to complete the installation. Compared to existing technologies, this method is simpler to operate and solves the problems existing in existing technologies. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] See Figure 1 and Figure 2As shown in the figure, the present invention provides a building climbing scaffold for construction engineering, which mainly includes a first mounting rod 1, a second mounting rod 2, two connecting rods 3 and several foot pedals 4. The figure shows three foot pedals 4, but there may be more in actual use. These foot pedals 4 are installed in the same way, so this embodiment only introduces the case of three pedals.

[0025] The first mounting rod 1 and the second mounting rod 2 serve as the left and right support rods of the climbing frame, and are set opposite to each other. Furthermore, the opposite surfaces of the first mounting rod 1 and the second mounting rod 2 are provided with a first slot 11 and a second slot 21 for inserting the two ends of the foot pedal 4, respectively. Figure 1 As shown, the first mounting rod 1 has three first slots 11 evenly distributed along the height direction on the side facing the second mounting rod 2. Similarly, the second mounting rod 2 has three second slots 21 evenly distributed along the height direction on the side facing the first mounting rod 1. The three first slots 11 and three second slots 21 are horizontally aligned and aligned. Two connecting rods 3 are respectively located at the upper and lower ends of the first mounting rod 1 and the second mounting rod 2. The first mounting rod 1, the second mounting rod 2, and the two connecting rods 3 form a rectangular frame, and three foot pedals 4 are installed inside this rectangular frame. The first end of the connecting rod 3 is connected to the drive mechanism inside the first mounting rod 1 and moves horizontally relative to the first mounting rod 1 under the drive mechanism, meaning the connecting rod 3 can move closer to or further away from the first mounting rod 1. The second end of the connecting rod 3 is fixedly connected to the second mounting rod 2. Therefore, the horizontal movement of the connecting rod 3 can move the second mounting rod 2 together, changing the relative distance between the first mounting rod 1 and the second mounting rod 2 while the first mounting rod 1 remains stationary.

[0026] Furthermore, each of the three second slots 21 on the second mounting rod 2 is equipped with a spring 5. The spring 5 is used to apply an outward springing force to the foot pedal 4 inserted therein. The spring 5 can be a straight spring, with one end fixedly connected to the bottom of the second slot 22. The second end of the foot pedal 4 inserted into the second slot 22 overcomes the spring force by compressing the spring 5.

[0027] Furthermore, the drive mechanism is used to realize the horizontal movement of the connecting rod 3. It is easy to imagine that an electric push rod, hydraulic push rod, or similar mechanism could be used. This embodiment provides a manually operated drive mechanism, which is not only convenient to operate but also energy-saving. This manually operated drive mechanism mainly consists of a transmission rod 21, two pairs of worm gears, two threaded rods 64, a pair of bevel or helical gears, and a crank handle 67. The specific structure and working principle are as follows:

[0028] The transmission rod 21 is rotatably installed in the vertical space within the first mounting rod 1. Two worm gears 62 are coaxially connected to both ends of the transmission rod 21, corresponding to the positions of the connecting rods 3. The interior of the first mounting rod 1 is hollowed out at a location relatively far from the first slot 11 to form a vertical space with closed ends. The length of the vertical space is not less than the distance between the two connecting rods 3, thus accommodating a transmission rod 61 of considerable length. The two worm gears 62 are coaxially connected to both ends of the transmission rod 61, corresponding to the positions of the two connecting rods 3. The transmission rod 61 is rotatably installed in the vertical space within the first mounting rod 1. The two ends of the transmission rod 61 can be rotatably connected to the inner walls of the first mounting rod 1 at both ends of the vertical space via bearings, thereby achieving rotatable installation of the transmission rod 61. The rotation of the transmission rod 61 will naturally drive the worm gears 62 on it to rotate.

[0029] The threaded rod 64 has a worm 63 coaxially connected to its first end, which meshes with the worm gear 62. The second end of the threaded rod 64 passes through a hole in the first mounting rod 1 and is threadedly connected to an internally threaded hole at the center of the first end of the connecting rod 3. Therefore, the rotation of the worm gear 62 can drive the worm 63 and the threaded rod 64 to rotate synchronously. The threaded hole at the center of the first end of the connecting rod 3 is threadedly connected to the threaded rod 64. Since the connecting rods 3 are arranged both above and below, their rotation is restricted. Therefore, the rotation of the threaded rod 64 will cause the connecting rod 3 to move horizontally, moving the second mounting rod 2 at the other end of the connecting rod 3 along with it.

[0030] The first bevel tooth 65 and the second bevel tooth 66 mesh with each other, and the first bevel tooth 65 is coaxially connected to the middle part of the transmission rod 61;

[0031] A crank handle 67 has its first end coaxially connected to the second bevel gear 66 and rotatably mounted on the first mounting rod 1. The second end of the crank handle 67 protrudes through an opening on the first mounting rod 1, forming an operating section. A bearing is used between the crank handle 67 and the opening on the first mounting rod 1 to achieve rotatable mounting of the crank handle 67. The operator can rotate the crank handle 67 via the operating section outside the first mounting rod 1, causing the second bevel gear 66 to rotate along with the crank handle 67, driving the first bevel gear 65 and the transmission rod 61 to rotate synchronously.

[0032] The working principle of the climbing formwork in this invention is as follows:

[0033] Cooperate Figure 1When the foot pedal 4 is damaged and needs replacement, the crank handle 67 is turned, which in turn drives the second bevel gear 66 to rotate. The rotation of the second bevel gear 66 drives the first bevel gear 65 to rotate, which in turn drives the transmission rod 61 to rotate. The rotation of the transmission rod 61 drives the worm gear 62 to rotate, which in turn drives the worm 63 to rotate. The rotation of the worm 63 drives the threaded rod 64 to rotate, which in turn drives the connecting rod 3 to move to the right. Since the connecting rods 3 are arranged at both the top and bottom, the second mounting rod 2 moves to the right as a whole. When the foot pedal 4 is about to come out of the first slot 11 but has not yet come out, the damaged foot pedal 4 is pushed to the right. The foot pedal 4 overcomes the spring force and moves into the second slot 21. The first end of the foot pedal 4 comes out of the first slot 11. Then, the foot pedal 4 is rotated at a certain angle to pull the second end out of the second slot 21, completing the disassembly. The above process is then reversed to complete the installation. Compared with the existing technology, the operation is simpler and solves the problems existing in the existing technology.
