DETAILED DESCRIPTION

[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] A construction engineering lifting device according to a preferred embodiment of the present invention will be described in detail below.

[0021] Embodiment 1, as Figure 1-Figure 7 As shown, it includes a crossbeam 1, and a placement mechanism 2 is arranged below the crossbeam 1; A support seat 3 is fixedly installed at the bottom of the crossbeam 1, and the support seat 3 is symmetrically arranged in two groups. The placement mechanism 2 includes a support plate 201 arranged under the crossbeam 1, and the support plate 201 is arranged in an arc shape. A first placement plate 202 is arranged above the support plate 201, and a second placement plate 203 is arranged below the first placement plate 202. The first placement plate 202 and the second placement plate 203 are arranged in a ring in several groups. The overlapping part of the first placement plate 202 and the second placement plate 203 is rotatably connected, and a connecting piece 204 is fixedly connected between the first placement plate 202 and the second placement plate 203. A third placement plate 205 is rotatably installed at one end of the first placement plate 202, and a fourth placement plate 206 is rotatably installed at one end of the second placement plate 203. The third placement plate 205 is rotatably connected with the fourth placement plate 206. A sliding groove 207 is opened on the surface of the support plate 201, and the sliding groove 207 is symmetrically arranged in two groups. The first placement plate 202 and the second placement plate 203 can slide on the surface of the support plate 201 through the sliding groove 207; An arc plate 208 is slidably mounted at the bottom of the support plate 201 . Two groups of arc plates 208 are symmetrically arranged and fixedly connected to the connecting piece 204 . An adjustment mechanism 4 is arranged on one side of the support seat 3 . The adjustment mechanism 4 is fixedly connected to the arc plate 208 via a first cable 401 .

[0022] First, the staff places cement and bricks on the platform composed of the first placement plate 202 and the second placement plate 203, and then controls the external driving mechanism to drive the support plate 201 to move upward or downward, thereby driving the cement and bricks on the surface of the first placement plate 202 and the second placement plate 203 to rise and fall. If there is strong wind, by controlling the first placement plate 202 and the second placement plate 203, the connecting piece 204 slides inside the sliding groove 207, so that the first placement plate 202 and the second placement plate 203 can be unfolded in a scissor shape. At the same time, because it is set in an arc shape, during the unfolding At the same time, the bottom connecting piece 204 can drive the arc plate 208 to slide at the bottom of the support plate 201, thereby forming a nearly circular shape, thereby covering the cement and bricks inside thereof, and protecting them in windy weather, preventing the wind from blowing them away and causing danger by falling. At the same time, when it is necessary to transport building items such as steel bars, the first placement plate 202 and the second placement plate 203 reach the final state when unfolded, thereby driving the third placement plate 205 and the fourth placement plate 206 to unfold, thereby forming a circular shape, which can play a certain clamping and fixing role for the steel bars; By setting up the placement mechanism 2, it can be unfolded into a circle when lifting the steel bars, thereby enhancing the clamping ability and stability of the steel bars; while it will not be unfolded when transporting cement bricks, thus avoiding unnecessary space occupation and complicated operations, achieving a balance between specialization and versatility, and at the same time, the arc-shaped plate 208 when unfolded can prevent the material from falling or being affected by the external environment during transportation, thereby enhancing the protection of the material.

When the placing mechanism 2 is lifted or lowered, the outward pulling force can provide a certain stability to the arc plate 208. At the same time, when the arc plate 208 is driven to present a circular shape, the second cables 406 will be close to each other, so that the lifting force of the second cables 406 is a vertical force, which further improves the stability during transportation; By using the adjustment mechanism 4 and adjusting the tension of the first cable 401, a balanced outward tension can be formed to help resist tilting or swinging during the lifting process, ensure that the whole remains vertical, prevent unnecessary shaking or loss of control, and improve the overall stability. At the same time, during the lifting process, the material may tilt or deflect due to the unstable center of gravity, causing the placement mechanism 2 to tilt.
