DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Embodiment 1

[0023] Reference Figure 1 This embodiment provides a lifting device for profile installation, the device includes a lifting device body, a lifting cantilever 1 and a lifting mechanism 2, one end of the lifting cantilever 1 is fixedly connected to the top of the lifting device body, and the lifting mechanism 2 is arranged on the lifting cantilever 1, and is used to lift the profile. For those skilled in the art, the lifting mechanism 2 on the lifting device belongs to conventional technical means, and its structure will not be described in detail here.

[0024] Reference Figure 2 and Figure 3In this embodiment, the device further comprises a profile fixing mechanism 3, which comprises an upper fixing part 301 and a lower fixing part 302 which are parallel to each other. The top of the upper fixing part 301 is connected to the lifting mechanism 2, and a first slide groove 303 is arranged at the bottom thereof. A second slide groove 304 is arranged at the top of the lower fixing part 302, and a first clamping part 305 and a second clamping part 306 are arranged between the upper fixing part 301 and the lower fixing part 302. The upper ends of the first clamping part 305 and the second clamping part 306 are both slidably arranged in the first slide groove 303, and the lower ends of the first clamping part 305 and the second clamping part 306 are both slidably arranged in the second slide groove 304. The left and right ends of the first slide groove 303 and the second slide groove 304 are both provided with a first push rod motor 307, and the push rod end of the first push rod motor 307 is connected to one side of the first clamping part 305 or the second clamping part 306.

[0025] In this embodiment, before hoisting the profile, the worker first passes the profile between the upper fixing part 301 and the lower fixing part 302, and tries to make the middle part of the profile between the upper fixing part 301 and the lower fixing part 302. Then, the first push rod motors 307 on the left and right sides of the first slide 303 and the second slide 304 respectively push the first clamping part 305 and the second clamping part 306 to move toward the profile, so that the first clamping part 305 and the second clamping part 306 clamp the profile from the left and right sides of the profile respectively to prevent the profile from shaking and falling during the hoisting process. After the profile is hoisted to the specified position, the first push rod motor 307 drives the first clamping part 305 and the second clamping part 306 to move away from the profile, so that the worker can remove the profile from the profile fixing mechanism 3. The device improves the stability of the profile during the lifting process through the profile fixing mechanism, avoiding safety accidents caused by the shaking and falling of the profile. At the same time, workers do not need to use ropes to fix the profile, and the fixing and removal of the profile are more convenient.

[0026] As an optional embodiment, the first clamping portion 305 and the second clamping portion 306 are both provided with an anti-slip portion 4 on one side opposite to the other, and the anti-slip portion 4 may be an anti-slip pad. The provision of the anti-slip portion 4 can increase the friction between the profile and the profile, thereby further preventing the profile from sliding.

[0027] In this embodiment, the first clamping part 305 and the second clamping part 306 both include an upper sleeve 561 and a lower sleeve 562. The lower sleeve 562 is slidably sleeved on the upper sleeve 561. The top of the upper sleeve 561 is connected to the upper fixing part 301, and the bottom of the lower sleeve 562 is connected to the lower fixing part 302. A second push rod motor 5 is provided at the bottom of the lower sleeve 562, and the push rod end of the second push rod motor 5 is connected to the top of the upper sleeve 561. The second push rod motor 5 can drive the upper sleeve 561 to move away from the lower sleeve 562, thereby increasing the distance between the upper fixing part 301 and the lower fixing part 302, so that the profile fixing mechanism can adapt to profiles of different heights and improve its application range.

[0028] The main body of the hoisting device includes a fixed base 6, an electric turntable 7 is arranged on the fixed base 6, a rotating base 8 is arranged on the rotating end of the electric turntable 7, a support rod 9 is arranged on the top of the rotating base 8, and one end of the hoisting cantilever 1 is fixedly connected to the top of the support rod 9. The electric turntable 7 is used to drive the rotating base 8 to rotate in a clockwise or counterclockwise direction.

[0029] In this embodiment, the first push rod motor, the second push rod motor, and the electric turntable can all adopt known models of existing products on the market.

[0030] Embodiment 2

[0031] Based on the above embodiment, the difference between this embodiment and the above embodiment is that:

[0032] Reference Figure 4 A camera 10 is disposed at the bottom of the lower fixing portion 302, and the camera 10 is connected to a host computer signal.

[0033] At the same time, an audible and visual alarm 11 is arranged on the main body of the hoisting device, and the audible and visual alarm 11 is connected to the host computer through a control circuit.

[0034] In this embodiment, the camera 10 is used to collect video images under the profile fixing mechanism in real time and transmit the video images to the host computer. The host computer runs the existing personnel recognition software to identify whether there are people in the video images, so as to determine whether there are people staying under the hoisted profile. If it is recognized that a person is staying, the host computer controls the sound and light alarm 11 to alarm, thereby prompting the operator and the staying personnel to pay attention to avoid safety accidents.

[0035] As an optional embodiment, a groove 12 is provided at the bottom of the upper fixing part 301 or the top of the lower fixing part 302, and a round rod 13 connected to the inner wall of the groove 12 is provided in the groove 12, a roller 14 is rotatably mounted on the round rod 13, a plurality of protrusions are provided on the body of the roller 14, a reflective sheet 15 is provided at the end of the roller 14, and a light emitter 16 and a light receiver 17 are provided on the inner wall of the groove 12, and the light receiver 17 is connected to the host computer signal. Figure 5 and Figure 6 They are respectively a schematic diagram of the top view of the structure of the lower fixing part when the groove 12 is arranged on the lower fixing part and a schematic diagram of the structure enlargement of the position of the groove 12.

[0036] In this optional embodiment, in the initial state of the roller 14, the reflective sheet 15 will stay opposite the light emitter 16 and the light receiver 17, the light emitted by the light emitter 16 will be reflected by the reflective sheet 15, and the reflected light will be received by the light receiver 17. After receiving the reflected light, the light receiver 17 will send a signal to the upper computer. After the profile is fixed by the profile fixing mechanism, the raised part on the barrel of the roller 14 will contact the surface of the profile. When the profile moves relative to the profile fixing mechanism, the profile will drive the roller 14 to rotate due to the relative friction. At this time, the position of the reflective sheet 15 will change due to the rotation of the roller 14, so that the light receiver 17 cannot receive the light reflected by the reflective sheet 15, resulting in a change in the state of the signal sent to the upper computer. The upper computer determines whether the profile moves according to the state of the signal sent by the light receiver 17. If the profile moves during the hoisting process, the upper computer will control the sound and light alarm 11 to sound an alarm, thereby prompting the operator to pay attention to whether the profile moves during the hoisting process to avoid the occurrence of safety accidents.

[0037] In this embodiment, the camera, sound and light alarm, light transmitter and light receiver can all adopt known models of existing products on the market. The control circuit is a conventional circuit for those skilled in the art, and its circuit connection relationship will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
