Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a cylindrical steel formwork calibration device. Background Technology

[0002] According to the cylindrical steel formwork calibration device disclosed in CN214364931U, an adjustable cylindrical steel formwork center calibration device is disclosed, which mainly includes a calibration plate, a plumb bob plate, an automatic rope winding mechanism, a cable, a detection plumb bob, etc. The automatic rope winding mechanism includes a motor, a roller is provided at the output end of the motor, a cable is provided on the roller, the roller is provided on the plumb bob plate through a bearing seat, the cable is provided on the automatic rope winding mechanism, a through hole is provided in the middle of the plumb bob plate, and the detection plumb bob is provided through the through hole.

[0003] However, the following problems still exist in practical applications: Based on the connection method, functional requirements and structural rationality described in the claims and specification of this technical solution, it can be seen that the device needs to be placed on the top of the steel template several times during use, and each steel template needs to be calibrated and measured separately. This results in: the flexible cable connected to the detection plumb bob lacks a limiting measure, but the calibration plate, plumb bob plate, etc. need to be frequently removed and installed, which will cause the cable to shake each time, causing the detection plumb bob to swing and become unstable, increasing the waiting time and delaying the calibration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical steel formwork calibration device. When detecting the drop of a plumb bob, the device uses a telescopic limiting mechanism to allow the guide tube to follow and be sleeved on the outside of the cable, thus physically limiting the plumb bob's sway amplitude and time, and improving calibration efficiency. When detecting the plumb bob's rise, the device can drive the guide tube to rise together, and the telescopic limiting mechanism will retract accordingly, thereby reducing the space occupied by the entire mechanism and the guide tube, and always maintaining the limiting effect on the cable.

[0005] The specific technical solution adopted by this utility model is as follows: A cylindrical steel formwork calibration device includes a cable that descends from the top of the calibration plate via an automatic rope winding mechanism. A detection plumb bob is fixedly connected to the end of the cable. A guide tube is coaxially arranged below the calibration plate and is sleeved on the outside of the cable. Both ends of the guide tube are integrally formed with tapered tubes. A counterweight ring is fixedly connected to the outer wall of the guide tube. The counterweight ring is adjustablely connected to the calibration plate through an outer telescopic limiting mechanism.

[0006] A non-contact gap is formed between the guide tube and the cable, and the radial distance of the gap is 1-2 mm.

[0007] The periphery of the tapered tube is machined with a rounded chamfer.

[0008] The telescopic limiting mechanism includes several connecting rods that are uniformly fixed to the outer wall of the counterweight ring in a circumferential direction.

[0009] A connecting plate is fixedly connected to the end of the connecting rod, and an extension rod is fixedly connected to one side of the connecting plate.

[0010] The bottom of the calibration plate is evenly distributed with several multi-stage telescopic tubes that correspond to and match the connecting rod.

[0011] The exposed end of the multi-stage telescopic tube is detachably connected to the connecting plate via a fastening bolt.

[0012] The outer wall of the base tube of the multi-stage telescopic tube is fixedly connected with an elastic clamp for movably engaging with the extension rod.

[0013] The technical effects achieved by this utility model are as follows: when detecting the fall of the plumb bob, the telescopic limiting mechanism can make the guide tube follow and be sleeved on the outside of the cable to physically limit it, thereby reducing the swing amplitude and time of the plumb bob and improving the calibration efficiency. When the plumb bob rises, it can drive the guide tube to rise together, and the telescopic limiting mechanism will retract accordingly, thereby reducing the space occupied by the entire mechanism and the guide tube, and always maintaining the limiting effect on the cable.

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] This utility model provides a cylindrical steel formwork calibration device based on the structure of patent CN214364931U, which mainly improves the limiting of cables and detection plumb bobs; except for the structural components mentioned in this utility model, the rest of the structure and principle are retained unchanged according to the original patent, and the specific structure can be found in the embodiment of the original patent.

[0018] like Figures 1-3 As shown, a cylindrical steel formwork calibration device includes a cable 101 that descends from the top of a calibration plate 1 via an automatic rope winding mechanism. A detection plumb bob 102 is fixedly connected to the end of the cable 101. A guide tube 2 is coaxially positioned below the calibration plate 1, sleeved around the cable 101, forming a non-contact gap with a radial distance of 1-2 mm between the guide tube 2 and the cable 101. Both ends of the guide tube 2 are integrally formed with tapered tubes 201, the periphery of which is rounded. A counterweight ring 202 is fixedly connected to the outer wall of the guide tube 2. The counterweight ring 202 is extended and retracted from the outer side. The positioning mechanism is adjustablely connected to the calibration plate 1. The telescopic limiting mechanism includes several connecting rods 203 that are uniformly fixed to the outer wall of the counterweight ring 202. The end of the connecting rod 203 is fixedly connected to the connecting plate 204. An extension rod 205 is fixedly connected to one side of the connecting plate 204. Several multi-stage telescopic tubes 206 that correspond to and match the connecting rods 203 are evenly distributed circumferentially at the bottom of the calibration plate 1. The exposed end of the multi-stage telescopic tube 206 is detachably connected to the connecting plate 204 through a fastening bolt 207. An elastic clip 208 is fixedly connected to the outer wall of the base tube of the multi-stage telescopic tube 206 for movably engaging with the extension rod 205.

[0019] According to the above structure, in accordance with the original patent structure, the automatic rope winding mechanism at the top of the calibration plate 1 can drive the winding of the cable 101, thereby causing the detection plumb bob 102 to rise and fall. In order to keep the flexible cable 101 stable during winding and unwinding or the entire mechanism's loading and unloading movement, the guide tube 2 is sleeved on the outside of the cable 101 for limiting. Specifically: when the entire calibration device is placed on the top of the steel template, when the detection plumb bob 102 falls, due to the effect of gravity and the increase in weight of the counterweight ring 202, the guide tube 2 can move downward accordingly. At the same time, the exposed end of the multi-stage telescopic tube 206 is extended through the connecting rod 203. The number of connecting rods 203 and multi-stage telescopic tubes 206 is preferably set to 3, so as to maintain the limiting effect on the guide tube 2 with the minimum number. Furthermore, by vertically extending and retracting the multi-stage telescopic tube 206, the guide tube 2 is restricted to move horizontally, thus placing the guide tube 2 below the calibration plate 1 to horizontally limit the cable 101, thereby significantly reducing its sway amplitude. At the same time, the outwardly expanding cone and rounded corners of the tapered tube 201 can avoid friction with the cable 101 during vertical lifting and lowering, reducing wear on the cable 101. When the cable 101 is wound and the detection plumb bob 102 is raised, the detection plumb bob 102 pushes the tapered tube 201 upward, moving upward together with the guide tube 2 and the connecting rod 203. The exposed end of the multi-stage telescopic tube 206 retracts. After the detection plumb bob 102 stops rising, the operator can temporarily fix the position of the connecting rod 203 by inserting the extension rod 205 into the corresponding elastic clip 208, so that the entire telescopic limiting mechanism remains stable during storage or transfer. Before the detection plumb bob 102 descends again, the extension rod 205 and the elastic clip 208 can be separated in advance.

[0020] The working principle of this utility model is as follows: Based on the original patented design of the mechanism layout, the automatic rope winding mechanism set on the top of the calibration plate 1 can drive the cable 101 to realize the winding and unwinding action, thereby driving the detection plumb bob 102 to complete the lifting and lowering movement. In order to ensure the stability of the flexible cable 101 during the winding and unwinding operation and the overall loading and unloading movement of the mechanism, a guide tube 2 is specially set to effectively limit it. Furthermore, the specific implementation method is as follows: When the entire calibration device is placed on top of the steel template and the detection plumb bob 102 is in a free-falling state, under the combined influence of gravity and the additional load of the counterweight ring 202, the guide tube 2 can be synchronously displaced in the vertical direction, and the exposed end of the multi-stage telescopic tube 206 can be extended outward through the connecting rod 203. Furthermore, in order to achieve efficient limiting, the connecting rod 203 and the multi-stage telescopic tube 206 are both arranged in three symmetrical groups to achieve effective constraint on the guide tube 2 with the minimum number of configurations. Through the axial telescopic movement of the multi-stage telescopic tube 206, the horizontal displacement of the guide tube 2 can be precisely limited, so that it is stably located below the calibration plate 1, forming an effective horizontal limit on the cable 101 and significantly reducing the swaying amplitude of the cable 101. Furthermore, the tapered tube 201 adopts an outwardly expanding tapered opening design and its periphery is rounded, which can effectively avoid frictional contact when the cable 101 moves vertically, greatly reducing the wear of the cable 101. When the cable 101 performs a winding action and the detection plumb bob 102 rises, the detection plumb bob 102 will push the tapered tube 201 upward, driving the guide tube 2 and the connecting rod 203 to move upward synchronously. At this time, the exposed end of the multi-stage telescopic tube 206 retracts accordingly. Furthermore, after the test plumb bob 102 stops rising, the operator can insert the extension rod 205 into the corresponding elastic clip 208 to temporarily fix the connecting rod 203, ensuring that the telescopic limit mechanism remains stable during storage or transportation. If the test plumb bob 102 needs to be lowered again, the extension rod 205 and the elastic clip 208 need to be separated in advance.

[0021] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
