Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a material hoist for construction engineering. Background Art

[0002] In construction projects, hoists can quickly transport large amounts of bricks, wood, steel and other materials to designated areas on construction sites, saving workers' time and energy and also saving space on the construction site.

[0003] Application No. 202321276415.2 discloses a material hoist for construction projects, which opens the positioning mechanism to clamp the material box, then opens the lifting mechanism, pulls the sliding seat up, and simultaneously opens the driving mechanism to drive the positioning mechanism and the material box to move above the buffer plate, thereby avoiding the trouble of manually moving the material box to the top of the buffer plate. When the material box falls accidentally, it can still fall onto the buffer plate, thereby reducing the chance of the material box being damaged.

[0004] The lifting structure of the above application has only one set, which has poor stability and is not convenient for workers to retrieve materials due to the limitation of the device position when working at height. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a material hoist for construction engineering, which solves the problems raised in the above-mentioned background technology.

[0010] Preferably, a weight sensor is installed inside the second plate body, a controller is installed at the bottom of the second plate body, a display screen is provided on the controller, and the controller is electrically connected to the weight sensor and the display screen respectively.

[0011] Preferably, the magnet sheet is made of cobalt-chromium-iron magnetic alloy.

[0012] The utility model provides a material hoist for construction engineering, which has the following beneficial effects:

[0013] 1. The material hoist for construction projects can rotate simultaneously through two sets of threaded columns between the base and the support frame under the action of the bevel gear set, driving the support plate to rise and fall, and transporting materials, which is beneficial to increase stability. The support plate is a combined structure. Through the sliding connection between the first plate body and the second plate body, the second plate body can drive the material to move after the material is lifted, shortening the distance between the material and the staff, and facilitating the material to be taken.

[0014] 2. The material hoist for construction projects has a sliding structure composed of a slide groove and a slider in the first plate body. Under the action of the magnet sheet in the slide groove and the magnetic metal sheet on one side of the slider, it is beneficial to increase the friction between the slide groove and the slider, so that the second plate body is not easy to automatically move. A weight sensor is installed in the second plate body to facilitate weighing of materials and remind workers to prevent materials from being too heavy and causing safety hazards during lifting.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a material hoist for construction engineering, including a base 1, a support frame 2 is installed on the top of the base 1, both sides of the support frame 2 are sleeved with limit sleeves 3, a support plate 4 is connected between the two limit sleeves 3, two threaded columns 5 are rotatably connected between the base 1 and the support frame 2, the two threaded columns 5 both penetrate the support plate 4 and are threadedly connected to the support plate 4, so that the support plate 4 is lifted and lowered with the rotation of the two threaded columns 5, which is convenient for lifting goods, a limit slot 6 is provided inside the support frame 2, and two first bevel gears 7 and two second bevel gears 8 are rotatably connected inside the limit slot 6, and the two first bevel gears 7 are connected between them. , the two second bevel gears 8 are respectively connected to the two threaded columns 5, and the two first bevel gears 7 are respectively meshed with the two second bevel gears 8, so that the two first bevel gears 7 and the two threaded columns 5 are transmitted, and the two threaded columns 5 can rotate at the same time and keep consistent, which is conducive to increasing the stability of the support plate 4. A motor 9 is installed on one side of the support frame 2, and the output end of the motor 9 is connected to one of the first bevel gears 7 to provide power for the rotation of the first bevel gear 7 and the threaded column 5. The support plate 4 includes a first plate body 41, and the first plate body 41 has two threaded holes 10 matched with the threaded columns 5, and the first plate body 41 has a groove 42. The structure of the first plate body 41 is concave, and a slide groove 43 is provided inside the first plate body 41 and on both sides corresponding to the groove 42. A slider 44 is slidably connected inside the slide groove 43, and a second plate body 45 is connected between the two sliders 44. The combined structure allows the second plate body 45 to slide out of the groove 42, shortening the distance between the second plate body 45 and the staff, making it easier to take the materials on the second plate body 45. A magnet sheet 13 is installed inside the slide groove 43, and a magnetic metal sheet 14 is installed on the side of the slider 44 close to the magnet sheet 13. The adsorption between the magnet sheet 13 and the magnetic metal sheet 14 is conducive to increasing the distance between the slider 44 and the slide groove 43. The friction between the slider 44 and the second plate 45 makes it difficult for the slider 44 and the second plate 45 to automatically move during lifting. The magnet sheet 13 is made of cobalt-chromium-iron magnetic alloy, and has very small magnetic force. Only weak magnetic force is conducive to preventing the magnet sheet 13 from being too magnetic and hindering the sliding of the slider 44 and the second plate 45. A weight sensor 11 is installed inside the second plate 45, and a controller 12 is installed at the bottom of the second plate 45. A display screen is provided on the controller 12. The controller 12 is electrically connected to the weight sensor 11 and the display screen respectively, so as to facilitate weighing the material and display it on the display screen to remind the staff to prevent the material from being too heavy and causing safety hazards during lifting.

[0022] In summary, when the material hoist for construction engineering is used, when the material is placed on the support plate 4, the weight sensor 11 in the second plate body 45 weighs it and displays it on the display screen on the controller 12. When the material is not overweight, the motor 9 drives the two first bevel gears 7 in the support frame 2 to rotate. Through the meshing of the two first bevel gears 7 with the two second bevel gears 8 respectively, and the connection of the two second bevel gears 8 with the two threaded columns 5 respectively, the two threaded columns 5 rotate accordingly. Since the two threaded columns 5 are both threadedly connected to the support plate 4, and the limiting sleeves 3 on both sides of the support plate 4 are respectively sleeved with the support frame 2, therefore, the two threaded columns 5 are restricted by the limiting sleeves 3 of the support frame 2, and the two threaded columns 5 rotate while driving the support plate 4 to rise and fall, so as to lift and transport the material. When the device is slightly far away from the staff, the sliders 44 sliding in the two slide grooves 43 in the first plate body 41 are respectively connected to the two sides of the second plate body 45, so that the second plate body 45 can slide, and the second plate body 45 can be pulled to move it together with the material to the staff. At this time, the material can be removed.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
