Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a lifting type construction engineering bracket. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities.

[0003] Construction engineering scaffolds are auxiliary tools used to assist workers in their work during construction. They are divided into many types, including temporary support brackets, hangers, etc. Taking hangers as an example, during the construction process of construction projects, workers are required to carry materials to higher places during some low-rise construction processes. The use of large cranes in low-rise construction processes is costly, and manual handling is too time-consuming and labor-intensive. At this time, engineering scaffolds are needed to help workers carry materials.

[0004] Existing engineering supports are often temporary stepped supports, which only build a ladder to help workers carry materials. However, this support cannot help workers lift and transport materials, resulting in workers still needing to carry them manually, which is more laborious. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, provides a lifting construction engineering support, including a base 3, a fixed box 1 is fixedly connected to both sides of the base 3, a locking assembly 2 is provided inside the fixed box 1, a lifting assembly 4 is provided inside the base 3, and the lifting assembly 4 includes two rotating shafts 405 movably connected to the inner wall of the base 3 through a bearing seat, the outer surface of the rotating shaft 405 is fixedly connected to the double-layer transmission sprocket 402, and the outer surface of the double-layer transmission sprocket 402 is connected to the vertical transmission chain The outer surfaces of the two vertical transmission chains 401 are fixedly connected with a connecting block 409 on the same side, and the connecting block 409 is fixedly connected with a lifting plate 407 on the side away from the vertical transmission chain 401. The side of the vertical transmission chain 401 away from the double-layer transmission sprocket 402 is connected to the single-layer transmission sprocket 406 for transmission. The same rotating shaft 405 is interspersed inside the single-layer transmission sprocket 406, and the rotating shaft 405 inside the single-layer transmission sprocket 406 is movably connected to the inner wall of the fixed box 1 through a bearing seat.

[0028] Specifically, a reduction motor 404 is fixedly connected to the bottom of the inner cavity of the base 3, and the output end of the reduction motor 404 is fixedly connected to one end of the rotating shaft 405 inside one of the double-layer transmission sprockets 402. A horizontal transmission chain 403 is connected between the two double-layer transmission sprockets 402. The interior of the lifting plate 407 and the upper surface of the base 3 are both provided with rectangular grooves for the movement of the vertical transmission sprocket, and the outer surface of the fixed box 1 is provided with the same rectangular groove. The outer surface of the lifting plate 407 is hinged with two guardrails 408, and the outer surface of the guardrail 408 is provided with a buckle.

[0029] Furthermore, the reduction motor 404 drives the two double-layer transmission sprockets 402 to rotate through the horizontal transmission chain 403, and the double-layer transmission sprocket 402 drives the vertical transmission chain 401 to move. During the movement of the vertical transmission chain 401, the lifting plate 407 is driven to rise and fall through the connecting block 409. Rectangular grooves for the movement of the vertical transmission chain 401 are provided inside the lifting plate 407 and on the upper surface of the base 3, and the same rectangular grooves are provided on the outer surface of the fixed box 1.

[0030] Example 2

[0031] Reference Figure 1 and Figure 3, which is the second embodiment of the present utility model, and is based on the previous embodiment. The locking assembly 2 includes a movable plate 203 movably connected to the inside of the fixed box 1, and a plurality of limit bars 202 are fixedly connected to the side of the movable plate 203 close to the lifting plate 407, and tooth plates 204 that cooperate with the limit bars 202 are fixedly connected on both sides of the lifting plate 407. Four magnets are fixedly connected to the side of the movable plate 203 close to the lifting plate 407, and four electromagnets 201 that cooperate with the magnets are fixedly connected to the inner wall of the fixed box 1.

[0032] Specifically, a rectangular opening is provided on one side of the fixed box 1 close to the lifting plate 407, which cooperates with the limit bar 202. Two limit blocks 205 are fixedly connected to the top of the movable plate 203. A slide groove is provided inside the fixed box 1 to cooperate with the limit block 205. A slide groove is provided at the bottom of the inner cavity of the fixed box 1 to cooperate with the bottom end of the movable plate 203. The length of the slide groove is sufficient for the movable plate 203 to drive the limit bar 202 to disengage from the tooth plate 204.

[0033] Furthermore, when the sensor on the lower surface of the top plate 5 senses the approach of the lifting plate 407, it controls the electromagnet 201 to be energized to attract the magnet on the outer surface of the movable plate 203, thereby driving the movable plate 203 to move toward the side close to the lifting plate 407, thereby driving the limit bar 202 to pop out from the fixed box 1, so that the limit bar 202 and the tooth plate 204 cooperate with each other, thereby achieving the locking effect of the lifting plate 407. When unlocking is required, the current direction of the electromagnet 201 is changed so that the electromagnet 201 changes from attracting the magnet to In order to repel the magnet and drive the movable plate 203 to move in the opposite direction, thereby driving the limit bar 202 to unlock, a slide groove is provided inside the fixed box 1 to cooperate with the limit block 205 and the bottom end of the movable plate 203, and the length of the slide groove is sufficient to allow the limit bar 202 to disengage from the tooth plate 204 as the movable plate 203 moves. When the movable plate 203 moves to the end of the slide groove away from the electromagnet 201, the magnetic force of the electromagnet 201 can still attract the magnet on the outer surface of the movable plate 203, thereby driving the movable plate 203 to move.

[0034] Working principle: When using the construction engineering support to assist in transporting materials, put the materials on the lifting plate 407, and then use the guardrail 408 and the lock to confine the materials in the lifting plate 407, and then start the reduction motor 404 to drive the two double-layer transmission sprockets 402 to rotate through the horizontal transmission chain 403, and the double-layer transmission sprocket 402 drives the vertical transmission chain 401 to move. During the movement of the vertical transmission chain 401, the lifting plate 407 is driven to rise and fall through the connecting block 409. When the lifting plate 407 is lifted to the specified height, the electromagnet 201 is started, and the magnet on the outer surface of the moving plate 203 is In cooperation with the electromagnet 201, the movable plate 203 moves toward the side close to the lifting plate 407, thereby driving the limit bar 202 to pop out from the fixed box 1, so that the limit bar 202 cooperates with the tooth plate 204 to achieve the locking effect of the lifting plate 407. After the material in the lifting plate 407 is taken out, the current of the electromagnet 201 is controlled to be reversed, thereby driving the electromagnet 201 to change from an attracting magnet to a repelling magnet, thereby driving the movable plate 203 to move in the opposite direction, thereby driving the limit bar 202 to unlock, and the reduction motor 404 can be reversed, thereby driving the lifting plate 407 to descend, and finally completing the material handling.
