Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction equipment, in particular to a telescopic intelligent supporting device. Background Art

[0002] The use of concrete is indispensable in construction projects. First, concrete is injected into the assembled concrete formwork. After pouring the concrete, a building support device is needed to fix the concrete formwork. The building support device is removed after the concrete is completely solidified.

[0003] The existing patent document with publication number CN205314609U proposes a support device whose length can be adjusted according to usage needs, has a wide range of use, good supporting effect, simple structure, and is easy to use. It avoids the problems in the prior art that the support rod length is not adjustable, which limits the use range of the support rod and the poor supporting effect.

[0004] However, in actual applications, it is found that the concrete formwork has just been poured and the concrete has not yet solidified. If the pressure of the support device on the concrete formwork is too high or too low, it will affect the quality of the finished product. For this reason, we provide a telescopic intelligent support device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a telescopic intelligent supporting device which can effectively support the concrete formwork and automatically adjust the pressure of the concrete formwork without affecting the quality of the finished product due to excessive or insufficient pressure on the concrete formwork.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a telescopic intelligent support device, comprising a support cylinder, a lifting mechanism is arranged in the support cylinder, the lifting mechanism comprises a power assembly fixedly connected to the inner bottom wall of the support cylinder, a lifting cylinder is threadedly connected to the outer surface of the output end of the power assembly, a stabilizing mechanism is arranged at the upper end of the lifting cylinder, the stabilizing mechanism comprises a box body fixedly connected to the upper end of the lifting cylinder, a connecting rod group is fixedly connected to the inner top wall of the box body, four special-shaped plates are hinged at the lower end of the connecting rod group through a pin shaft, a tension spring is fixedly connected to the side of the connecting rod group close to the power assembly, a control module is installed on the surface of the support cylinder, and a pressure sensor is installed on the surface of the box body.

[0007] Furthermore, the power assembly includes a servo motor and a screw, the servo motor is fixedly connected to the inner bottom wall of the support tube, the screw is fixedly connected to the output shaft end of the servo motor, the pressure sensor, the control module and the servo motor are electrically connected, the bottom surface of the support tube is fixedly connected to a base, the bottom surface of the base is fixedly connected to an anti-slip pad, and by providing the base, the contact area between the device and the ground can be increased, thereby improving the stability of the device, and its stability can be further improved by providing the anti-slip pad.

[0008] Furthermore, two symmetrical first limit grooves are provided on the inner side wall of the support cylinder, and two symmetrical first limit strips are fixedly connected to the surface of the lifting cylinder. The two first limit grooves are respectively matched with the two first limit strips. The cooperation between the first limit grooves and the first limit strips can effectively limit the support cylinder and the lifting cylinder, so that the lifting cylinder can only slide up and down inside the support cylinder, thereby enabling the lifting cylinder to be lifted and lowered more stably under the drive of the power assembly.

[0009] Furthermore, the end of the screw rod away from the servo motor is fixedly connected to a limit ring, the outer surface of the limit ring is slidably connected to the inner wall of the lifting cylinder, the limit ring fits the inner wall of the lifting cylinder, and the limit ring will slide on the inner wall of the lifting cylinder during the rising or falling process of the lifting cylinder, thereby preventing the screw rod from shaking during the rotation process.

[0010] Furthermore, the connecting rod group includes a mounting seat and four connecting rods. The mounting seat is fixedly connected to the inner top wall of the box body. The four connecting rods are respectively located on the four sides of the mounting seat. The four connecting rods are hinged to the mounting seat through pins. Since the connecting rods are hinged to the mounting seat, when the mounting seat descends or rises, the connecting rods will be driven to rotate around the mounting seat. The connecting rods are limited by the special-shaped plate, so the connecting rods rotate on the special-shaped plate at the same time.

[0011] Furthermore, the inner top wall of the box body is fixedly connected to a limit rod, the reserved hole of the mounting seat is slidably connected to the outer surface of the limit rod, and the limit rod is located inside the tension spring.

At the same time, the second limiting grooves and the second limiting strips can support the special-shaped plates when the special-shaped plates are used to make concrete formwork.

[0013] Compared with the prior art, the telescopic intelligent support device has the following beneficial effects:

[0014] 1. The utility model can drive the lifting cylinder to lift inside the supporting cylinder by setting a power component, so as to support the concrete formwork. By setting a tension spring, the connecting rod group can be pulled to slide, so as to squeeze the special-shaped plate outward, so that the special-shaped plate moves to the outside of the box body, thereby increasing the contact area between the device and the concrete formwork and improving the stability of the support for the concrete formwork. The power component can be controlled by the coordinated setting of the pressure sensor and the control module, so as to intelligently adjust the pressure of the device on the concrete formwork.

DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] As described in the background art, for a concrete formwork that has just been poured, the concrete has not yet solidified. If the pressure of the support device on the concrete formwork is too high or too low, it will affect the quality of the finished product. For this reason, this embodiment provides a telescopic intelligent support device.

[0025] See also Figures 1 to 6 This embodiment proposes a telescopic intelligent support device, including a support tube 1, a lifting mechanism 2 is arranged inside the support tube 1, the lifting mechanism 2 includes a power component 201 fixedly connected to the bottom wall of the support tube 1, and a lifting tube 202 is threadedly connected to the outer surface of the output end of the power component 201.

[0026] The power assembly 201 includes a servo motor 2011 and a screw rod 2012. The servo motor 2011 is fixedly connected to the inner bottom wall of the support tube 1. The screw rod 2012 is fixedly connected to the output shaft end of the servo motor 2011. The pressure sensor 4, the control module 5 and the servo motor 2011 are electrically connected. The bottom surface of the support tube 1 is fixedly connected to a base 6, and the bottom surface of the base 6 is fixedly connected to an anti-slip pad 7.

[0027] The base 6 can increase the contact area between the device and the ground, thereby improving the stability of the device. The anti-slip pad 7 can further improve the stability.

[0028] The start of the servo motor 2011 will drive the screw 2012 to rotate. The servo motor 2011 is widely used in various control systems. The servo motor 2011 can convert the input voltage signal into a mechanical output on the motor shaft, drag the controlled element, and thus achieve the control purpose.

[0029] The inner side wall of the support cylinder 1 is provided with two symmetrical first limiting grooves 203 , and the surface of the lifting cylinder 202 is fixedly connected with two symmetrical first limiting strips 204 , and the two first limiting grooves 203 are respectively matched with the two first limiting strips 204 .

[0030] The cooperation between the first limiting groove 203 and the first limiting strip 204 can effectively limit the support tube 1 and the lifting tube 202, so that the lifting tube 202 can only slide up and down inside the support tube 1 and cannot rotate inside the support tube 1, thereby enabling the lifting tube 202 to be lifted and lowered more stably under the drive of the power assembly 201.

[0031] One end of the screw rod 2012 away from the servo motor 2011 is fixedly connected to the limit ring 205 , and the outer surface of the limit ring 205 is slidably connected to the inner wall of the lifting cylinder 202 .

[0032] The limiting ring 205 fits with the inner wall of the lifting cylinder 202. When the lifting cylinder 202 is rising or falling, the limiting ring 205 will slide on the inner wall of the lifting cylinder 202, thereby preventing the screw rod 2012 from shaking during rotation, and effectively improving the rotation stability of the screw rod 2012.

[0033] A stabilizing mechanism 3 is disposed at the upper end of the lifting cylinder 202 . The stabilizing mechanism 3 includes a box body 301 fixedly connected to the upper end of the lifting cylinder 202 . A connecting rod group 302 is fixedly connected to the inner top wall of the box body 301 .

[0034] Starting the servo motor 2011 can drive the screw rod 2012 to rotate. The rotation of the screw rod 2012 will drive the lifting cylinder 202 limited by the first limit bar 204 to rise and fall. The lifting of the lifting cylinder 202 will also drive the box body 301 to rise and fall, thereby realizing the supporting effect of the device on the concrete formwork.

[0035] The connecting rod assembly 302 includes a mounting seat 3021 and four connecting rods 3022. The mounting seat 3021 is fixedly connected to the inner top wall of the box body 301. The four connecting rods 3022 are respectively located on four sides of the mounting seat 3021. The four connecting rods 3022 are hinged to the mounting seat 3021 through pins.

[0036] Since the connecting rod 3022 is hinged to the mounting seat 3021 , when the mounting seat 3021 descends or ascends, the connecting rod 3022 will be driven to rotate around the mounting seat 3021 . The connecting rod 3022 is limited by the special-shaped plate 303 , so the connecting rod 3022 rotates on the special-shaped plate 303 at the same time.

[0037] The inner top wall of the box body 301 is fixedly connected with a limiting rod 305, the reserved hole of the mounting seat 3021 is slidably connected with the outer surface of the limiting rod 305, and the limiting rod 305 is located inside the tension spring 304. By setting the limiting rod 305, the mounting seat 3021 can be limited to avoid shaking of the mounting seat 3021 during the lifting process, so that the mounting seat 3021 can be lifted and lowered more stably.

[0038] The lower end of the connecting rod group 302 is hinged with four special-shaped plates 303 through a pin shaft, and a tension spring 304 is fixedly connected to the side of the connecting rod group 302 and the power component 201 that is close to each other.

[0039] Two second limiting grooves 306 are provided on the four sides of the box body 301 , and the two sides of the four special-shaped plates 303 are fixedly connected with second limiting bars 307 , the second limiting grooves 306 are adapted to the second limiting bars 307 , and two rollers 308 are installed on the two sides of the four special-shaped plates 303 .

[0040] The second limiting groove 306 and the second limiting strip 307 are provided to limit and support the special-shaped plate 303, so that the sliding of the special-shaped plate 303 is more stable. At the same time, the second limiting groove 306 and the second limiting strip 307 can support the special-shaped plate 303 when the special-shaped plate 303 is used to make the concrete formwork.

[0041] See also Figure 3 The upper ends of the four special-shaped plates 303 are slidably connected to the reserved square holes of the box body 301. When the lifting cylinder 202 rises, the lifting cylinder 202 will move the box body 301 upward. The movement of the box body 301 will stretch the tension spring 304 through the mounting seat 3021. The elastic force of the tension spring 304 will pull the mounting seat 3021, causing the mounting seat 3021 to slide on the surface of the limit rod 305.

[0042] The downward moving mounting seat 3021 will cause the connecting rod 3022 to rotate on the mounting seat 3021 and the special-shaped plate 303 through the pin shaft. The rotating connecting rod 3022 will push the special-shaped plate 303, and the special-shaped plate 303 can move more smoothly through the roller 308 until the connecting rod group 302 moves to a horizontal state, pushing the special-shaped plate 303 to the outside of the box body 301, thereby increasing the contact area between the box body 301 and the concrete formwork, so that the device can more stably support the concrete formwork.

[0043] See also Figure 3 Since the width of the box body 301 is greater than the diameter of the reserved hole at the upper end of the lifting cylinder 202, the mounting seat 3021 will be limited by the reserved hole when it moves to the bottom surface of the box body 301. Therefore, the connecting rod group 302 can only move to a horizontal state. When the lifting cylinder 202 descends, the elastic force generated by the deformation of the tension spring 304 can pull the mounting seat 3021 back.

[0044] A control module 5 is installed on the surface of the support tube 1, and a pressure sensor 4 is installed on the surface of the box body 301. The pressure sensor 4 and the control module 5 belong to the existing technology and are not within the scope of the key description of this article. They are not excessively limited. They only need to be able to analyze and convert the signal parameters of the pressure. The power component 201 can be controlled by the coordinated setting of the pressure sensor 4 and the control module 5, and then the pressure of the device on the concrete formwork can be intelligently adjusted.

[0045] Working principle: When in use, first move the device to the required position, then start the power component 201. The start of the power component 201 will cause the lifting cylinder 202 to rise, and the lifting cylinder 202 will drive the box 301 to rise. At the same time, the tension spring 304 will pull the connecting rod group 302 to move, and the connecting rod group 302 will push the special-shaped plate 303 to move to the outside of the box 301, thereby increasing the contact area between the top of the device and the concrete formwork and improving the stability of the support for the concrete formwork. When the pressure sensor 4 contacts the concrete formwork, the pressure sensor 4 and the control module 5 can cooperate to intelligently adjust the pressure of the device on the concrete formwork to avoid excessive or insufficient pressure on the concrete formwork.
