[0022] Next, through embodiments and in combination with the drawings, the technical solutions of the present invention will be further specifically described.

[0023] Such as Figures 1 to 4An electromechanical installation safety protection device includes a base 3, a telescopic frame 4, a first driver (not shown in the figure), a support platform 5, a guardrail 6, a sensor 7, and a locking mechanism 8. The sensor 7 is installed on the base 3, the telescopic frame 4 is vertically installed on the upper side of the base 3, the first driver is used to drive the telescopic frame 4 to extend and retract vertically, the support platform 5 is horizontally installed on the upper end of the telescopic frame 4, the guardrail 6 is arranged around the support platform 5 and can move up and down along the support platform 5, and the locking mechanism 8 is installed on the support platform 5 to lock the guardrail 6.

[0024] The protective device has a retractable state. In the retractable state, the telescopic frame 4 is retracted to its shortest length, the upper end of the guardrail 6 is close to the upper side of the support platform 5, and the lower end of the guardrail 6 can be detected by the sensor 7.

[0025] With the above settings, the guardrail 6 can move up and down on the support platform 5 to adjust its height. When the guardrail 6 is lowered, it is convenient to store the safety protection device and also convenient to move tools and equipment onto the support platform 5 for subsequent high-altitude operations. In addition, the addition of sensor 7 enhances the safety of the safety protection device.

[0026] The base 3 of this application is placed on the ground. The telescopic frame 4 and the drive unit are based on existing scissor lift platforms and will not be described in detail here. When retracted, the telescopic frame 4 is shortened to its shortest length, and the distance from the top of the support platform 5 to the ground is 180cm to 250cm, specifically 200cm, facilitating workers to climb onto the support platform 5. The upper end of the guardrail 6 is close to the top of the support platform 5, and the distance from the top of the guardrail 6 to the top of the support platform 5 is less than or equal to 20cm, resulting in a small overall height of the safety protection device, making it easy to store in a warehouse. It also facilitates the transport of tools and equipment from the ground onto the support platform 5 for subsequent high-altitude operations. When workers climb onto the support platform 5, the transmission... When sensor 7 detects the lower end of guardrail 6, the first actuator cannot operate, preventing the support platform 5 from moving upwards without raising guardrail 6, thus preventing workers from falling from heights. When workers lift guardrail 6 on support platform 5, guardrail 6 slides upwards along support platform 5 and is then locked by locking mechanism 8 to prevent guardrail 6 from falling under gravity. At this time, guardrail 6 can prevent workers from falling from the edge of support platform 5. When the lower end of guardrail 6 is far away from sensor 7, sensor 7 cannot detect the lower end of guardrail 6, indicating that guardrail 6 has been raised. The first actuator can then drive support platform 5 upwards via telescopic frame 4 to lift workers, facilitating high-altitude electromechanical installation work.

[0027] As one implementation, the safety protection device also includes a walking mechanism, which includes wheels 9 rotatably connected to the base 3 and a second drive for driving the wheels 9.

[0028] The above settings facilitate the movement of safety protection devices.

[0029] The second drive of this application uses an electric motor, which drives the wheel 9. The wheel 9 rolls on the ground, and the safety protection device moves to the working location. A lithium battery is installed on the base 3 to supply power to the electric motor.

[0030] As an implementation, the guardrail 6 includes a handrail 61, a slide rail 62 and a cross bar 63. The handrail 61 is of rectangular structure and is arranged on the upper side of the support platform 5. There are four slide rails 62, which are vertically and fixedly connected to the four corners of the handrail 61 respectively. A number of the above cross bars 63 are fixedly connected between adjacent two slide rails 62; A slider 10 is fixedly connected to the edge of the support platform 5, and the slide rail 62 is slidably connected with the slider 10; In the retracted state, the lowermost cross bar 63 is detected by the sensor 7, and the lower side of the handrail 61 abuts against the support platform 5.

[0031] The support platform 5 of this application is basically of rectangular structure and is adapted to the handrail 61; As Figure 1 , when the upper end of the guardrail 6 is close to the upper side of the support platform 5, the lower end of the slide rail 62 is lower than the lower side of the support platform 5. When the operator climbs onto the support platform 5, the operator can lift the handrail 61 upward. The handrail 61 and the slide rail 62 move upward synchronously, and the locking mechanism 8 locks the slide rail 62. The support platform 5 supports the handrail 61 through the locking mechanism 8 and the slide rail 62. The handrail 61, the slide rail 62 and the cross bar 63 form a frame structure to prevent the operator on the upper side of the support platform 5 from falling from the edge of the support platform 5.

[0032] As an implementation, the locking mechanism 8 includes an electric cylinder 81 and a bolt 82. The electric cylinder 81 is fixedly connected to the upper side of the support platform 5 and is used to drive the axial movement of the bolt 82. A slot 18 is arranged on the slide rail 62. The safety protection device also includes a working state. In the working state, the distance between the upper side of the handrail 61 and the upper side of the support platform 5 is d, 80 cm < d < 140 cm, and the bolt 82 is inserted into the slot.

[0033] When the operator is working on the upper side of the support platform 5, the distance between the upper side of the handrail 61 and the upper side of the support platform 5 is greater than 80 cm and less than 140 cm, so that the handrail 61 is higher than the operator's waist to prevent the operator from falling. The electric cylinder 81 drives the bolt 82 to insert into the slot to lock the height of the guardrail 6; When the safety protection device needs to return to the retracted state, the electric cylinder 81 drives the bolt 82 to retract, and the bolt 82 is pulled out from the slot. The operator can slowly lower the guardrail 6 until the handrail 61 abuts against the upper side of the support platform 5.

[0034] As an implementation, the safety protection device also includes a ladder 11. The ladder 11 is vertically and fixedly connected to one side of the base 3, and the sensor 7 is installed at the upper end of the ladder 11.

[0035] Through the above settings, it is convenient for the operator to climb onto the support platform 5.

[0036] When the safety protection device of this application is in the retracted state, such as Figure 1 The lower end of the ladder 11 is close to the ground, the upper end of the ladder 11 is close to the lower end of the guardrail 6, and the upper end of the ladder 11 is close to the bottom horizontal bar 63. Workers on the ground can climb up to the support platform 5 by climbing the ladder 11 and the horizontal bar 63.

[0037] As one implementation, the support platform 5 includes an upper base plate 51, a support column 52 and a lower base plate 53. The lower base plate 53 is horizontally installed on the upper end of the telescopic frame 4. The upper base plate 51 is horizontally fixedly connected to the upper side of the lower base plate 53 through the support column 52. The slider 10 extends vertically, and the upper and lower ends of the slider 10 are fixedly connected to the upper base plate 51 and the lower base plate 53 respectively.

[0038] With the above configuration, the slide rail 62 is slidably connected to the support platform 5 via the slider 10.

[0039] As one implementation method, sensor 7 is configured as a photoelectric sensor.

[0040] The sensor 7 in this application is used to detect the bottommost crossbar 63. When the sensor 7 detects the crossbar 63, as... Figure 1 This indicates that the safety protection device is in the retracted state at this time, the guardrail 6 has not been lifted, the first actuator cannot be activated, and the workers on the upper side of the support platform 5 cannot fall; the sensor 7 cannot detect the crossbar 63, indicating that the guardrail 6 is lifted, the first actuator can be activated, and the support platform 5 is driven to move upward through the telescopic frame 4. The guardrail 6 can protect the workers and prevent them from falling from the edge of the support platform 5.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
