[0004] However, the above-mentioned disclosed scheme has the following shortcomings: during the actual use process of construction and installation, the construction materials need to be frequently lifted and transported. When the lifting structure of the above-mentioned device is in a high position during the process of lifting and transporting materials, it is necessary to continuously use a winding roller to tighten it to prevent the lifting structure from loosening. If it is in a static power-on state for a long time, it is easy to cause problems such as overheating of the driving device such as the motor, thereby reducing the service life of the driving structure.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] Example 1: Please refer to Figure 1-5 The utility model provides a technical solution: a safety construction frame for building construction, including a base 1, a support plate 4 connected by a first support rod 3 is arranged on the base 1, a connecting plate 8 is arranged on the base 1, a lifting member 9 is slidably arranged on the connecting plate 8, a rotating connecting bracket 14 is rotatably arranged on the connecting plate 8, a rotating limit plate 15 in contact with a fixed limit plate 16 is arranged on the side of the rotating connecting bracket 14, a supporting abutment member 17 is arranged on the side of the rotating connecting bracket 14 for locking and supporting the lifting member 9, a lifting telescopic rod 7 is arranged on the base 1, a waist-shaped hole is arranged on the connecting plate 8, and the output end of the lifting telescopic rod 7 passes through the waist-shaped hole of the connecting plate 8 and is connected to the side of the lifting member 9;

[0027] The lifting member 9 is rotatably provided with a rotating plate 10, and the rotating plate 10 is provided with a lifting support member 12 connected by a rotating connecting member 11, and a second support rod 13 is provided on the side of the lifting support member 12, and the second support rod 13 is in contact with the supporting abutment member 17 for unlocking the lifting member 9 to stop sliding.

[0028] The base 1 is provided with an auxiliary support component 2, which includes a roller 201, which is rotatably connected to the bottom of the base 1, a telescopic rod 202 is provided on the side of the base 1, a fixing part 203 is provided on the telescopic rod 202, and a ground nail 204 is slidably provided on the fixing part 203, and multiple groups of auxiliary support components 2 are distributed around the base 1.

[0029] A groove is provided on one side of the lifting member 9 close to the connecting plate 8, and the width of the groove is greater than the length of the supporting and abutting member 17. A transmission groove is provided on the bottom of the lifting member 9, and the width of the transmission groove is less than the width of the rotating plate 10. The width of the transmission groove is greater than the length of the rotating connecting member 11. The width of the supporting and abutting member 17 is less than the width of the lifting support member 12, and an inner buckle handle is provided on the rotating plate 10.

[0030] The device can effectively reduce the working pressure of the lifting and telescopic rod 7, avoid the lifting and telescopic rod 7 being in a continuous working state when the lifting member 9 is in a high and stationary state, and extend the service life of the lifting and telescopic rod 7.

[0031] When the device is in working state, the base 1 can improve the fixing and stabilizing effect of the device and the ground through the structure of the auxiliary supporting component 2, the structure of the roller 201 can facilitate the movement of the device, and the structure of the telescopic rod 202 can increase the spacing between the multiple groups of ground nails 204, thereby improving the lateral supporting force of the device and reducing the risk of the device tipping over.

[0032] When the base 1 is in a fixed state, the construction materials that need to be lifted and transported are placed on the top of the lifting member 9. At this time, the rotating plate 10 is blocked. After the goods are placed, the lifting member 9 is lifted and transmitted through multiple sets of lifting telescopic rods 7, thereby realizing the lifting and transportation of the goods.

[0033] When the lifting member 9 slides upward, the lifting support member 12 and the second support rod 13 will push the supporting abutment member 17 to rotate during the rising process. Due to the combined structure of the rotating limit plate 15 and the fixed limit plate 16, the rotating connecting bracket 14 can only rotate clockwise. Therefore, during the rising process, the supporting abutment member 17 is pushed to rotate clockwise, thereby clearing the position of the lifting support member 12 and ensuring that the lifting member 9 will not get stuck during the rising process.

[0034] When the lifting support member 12 rises above the supporting and abutting member 17, the rotatable connecting bracket 14 rotates in the opposite direction due to the gravity of the supporting and abutting member 17, and returns to the state where the rotating limit plate 15 and the fixed limit plate 16 are in contact with each other. At this time, the power supply of the lifting and telescopic rod 7 is disconnected, so that the second support rod 13 is pressed downward above the supporting and abutting member 17. Since the rotating limit plate 15 and the fixed limit plate 16 are in contact with each other at this time, the rotatable connecting bracket 14 cannot rotate in the opposite direction, thereby achieving the effect of the supporting and abutting member 17 supporting the second support rod 13. At this time, the lifting and telescopic rod 7 is in a power-off state, which can effectively extend the service life of the lifting and telescopic rod 7 of the device.

[0035] When the cargo on the lifting member 9 is transported, there is no obstruction at the top of the rotating plate 10, so it can be rotated. When the rotating plate 10 is rotated in the direction away from the connecting plate 8, the lifting support member 12 and the second support rod 13 can be moved in the direction away from the supporting abutment member 17 through the structure of the rotating connecting member 11, thereby achieving the effect of lowering and unlocking the device. When the second support rod 13 is away from the supporting abutment member 17 and does not contact the lifting member 9, the lifting member 9 can be lifted and slid freely. The device uses the rotating plate 10 to control the second support rod 13, which can ensure that the lifting member 9 is in an unloaded state when it needs to be lowered. At this time, the mass of the lifting member 9 is the smallest, and the overall center of gravity of the device is affected the least during the process of the lifting telescopic rod 7 driving the lifting member 9 to descend, thereby improving the overall stability of the device.

[0036] When the device is used in a high-altitude environment, the side baffle 603 can be erected by rotating the connecting piece 602 upward, thereby achieving the side protection effect of the device on the staff, and the combined structure of the rotating blocking piece 606 and the abutting piece 607 can achieve the effect that the rotating blocking piece 606 can only rotate in the direction close to the support plate 4, so that when the connecting piece 602 is rotating upward, the rotating blocking piece 606 will not block the connecting piece 602, and when the side baffle 603 is accidentally squeezed, the rotating blocking piece 606 can provide lateral support to the connecting piece 602, thereby preventing the side baffle 603 from loosening, thereby achieving the side protection effect of the side baffle 603 on the staff.

[0037] Embodiment 2: Figure 1-5 As shown, a safety construction frame for building construction disclosed in Example 2 of the utility model has a structure that is basically the same as that in Example 1, except that a ladder 5 is arranged on the side of the support plate 4, a protective component 6 is arranged on the bottom of the support plate 4, and the protective component 6 includes a rotating bracket 601, a connecting member 602 is rotatably arranged on the rotating bracket 601, a side baffle 603 is arranged on the connecting member 602, a rotating member 604 is arranged on the side of the support plate 4, a rotating shaft 605 is rotatably arranged on the rotating member 604, a rotating blocking member 606 is arranged on the rotating shaft 605, and an abutting member 607 is arranged on the support plate 4, a blocking groove is provided on the rotating blocking member 606, and a limiting protrusion is provided on the abutting member 607.

[0038] The structure of the protective component 6 is symmetrically distributed on both sides of the support plate 4, which can provide lateral protection for the staff when the device is used at a high place, avoiding problems such as accidental falling of the staff.
