Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a cement bag unloading device for building construction. Background Technology

[0002] Cement is an indispensable basic material in the construction industry. However, cement is usually transported and stored in bags, making the unloading and handling of cement on construction sites a heavy and time-consuming task. Traditional unloading methods often require a large amount of manual labor, which is not only inefficient but also poses safety hazards. Therefore, it is particularly important to develop an efficient, safe, and automated cement bag unloading device for construction. With the rapid development of the construction industry, the demand for cement bag unloading devices is also increasing. On the one hand, the demand for cement on construction sites is large, and traditional unloading methods cannot meet the needs of efficient construction. On the other hand, with the rise in labor costs, construction units have increased their demand for automated and intelligent unloading devices to reduce the labor intensity of workers and improve construction efficiency. In conclusion, the research and development of cement bag unloading devices for construction has broad market prospects and technological development space.

[0003] Chinese Patent Publication No. CN218434619U discloses an unloading device belonging to the field of concrete frame structure construction. It includes an upright post 1, diagonal brace 2, handrail 3, fixed rod 4, cantilever rod 5, fixed pulley 6, lifting rope 7, sliding roller 8, connecting plate 9, bottom longitudinal rod 10, and bottom transverse rod 11. In use, the construction worker holds the handrail of the unloading device and pushes it to the rear of the truck. Then, the lifting rope is released, and the cement, blocks, and other building materials on the truck are secured to the rope. The rope is then raised to detach the building materials from the truck, while simultaneously securing the rope to the fixed rod. The unloading device is then pulled along the handrail until it reaches the construction position. Finally, the rope is released to unload the building materials for construction work. The advantages are simple assembly, convenient operation, significantly reduced manpower, and lower construction costs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0028] Please see Figure 4 and Figure 5 This utility model provides a technical solution: a cement bag unloading device for construction, which is equipped with a slide rail 6 and a sliding plate 7 to facilitate workers to move cement bags from the truck bed to the device;

[0029] A guide rail 6 for limiting is fixedly installed on the top of the support plate 4. A slide plate 7 for support is inserted into the middle of the guide rail 6. A slot 18 for limiting is opened on the top of the guide rail 6. A fastening piece 19 for limiting is fixedly connected to one side of the guide rail 6. A roller 20 for sliding is rotatably connected to the bottom of the slide plate 7. A handle 21 for gripping is fixedly installed on one side of the slide plate 7. Therefore, during use, the slot 18 is used to limit the sliding range of the slide plate 7. The fastening piece 19 can fix the guide rail 6 to the top of the support plate 4. The roller 20 contacts the bottom of the guide rail 6 to reduce the frictional resistance of the slide plate 7 during sliding. The handle 21 makes it easy for workers to grip and push and pull the slide plate 7. Example 2

[0030] Please see Figure 1 and Figure 3 In order to enable the cement bags to be unloaded from the truck bed during use, the device is equipped with a support column 2, a slider 3 and a support plate 4;

[0031] A support column 2 is fixedly installed on the top of the base 1. A slider 3 for limiting is inserted inside the support column 2. A support plate 4 for supporting is fixedly installed on one side of the slider 3. A lead screw motor 10 is fixedly installed inside the support column 2. A vertical rod 11 for limiting is fixedly connected inside the support column 2. A threaded hole 12 for limiting is opened in the middle of the slider 3. A locking piece 13 for limiting is fixedly connected to one side of the slider 3. A guardrail 14 for connection is fixedly installed on one side of the support plate 4. A support leg 15 for supporting is fixedly installed at the bottom of the support plate 4. Therefore, in use... During the process, the lead screw motor 10 is configured so that its drive shaft engages with the threaded hole 12 of the slider 3 to drive the slider 3 to slide up and down within the support column 2. The upright rod 11 passes through the through hole of the slider 3 to prevent the slider 3 from deflecting during sliding. The locking piece 13 tightly connects the slider 3 and the support plate 4, thereby driving the support plate 4 to slide up and down. The guardrail 14 prevents the cement bag from slipping off the support plate 4 during loading and unloading. The support leg 15 increases the stability of the support plate 4. Example 3

A hinge 16 for connection is fixedly installed on one side of the side plate 5, and a locking buckle 17 is fixedly installed on the other side of the side plate 5. Therefore, during use, the caster wheel 8 facilitates the movement and positioning of the entire device, while the crossbar 9 increases the structural strength of the base 1. The hinge 16 allows the side plate 5 to rotate around the edge of the support plate 4. Furthermore, the locking buckle 17 engages with a locking seat on the support plate 4 when the side plate 5 is closed, locking the position of the side plate 5.

[0034] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

Then, drive the slider 3 to slide upward in the support column 2 through the screw motor 10, aligning it with the inside of the truck bed. Then, the worker holds the handle 21 on one side of the slide plate 7 and pushes the slide plate 7 from one end of the slide rail 6 into the truck bed. After loading the cement bag onto the slide plate 7, push the slide plate 7 into the top of the support plate 4. Then, drive the slider 3 to slide downward in the support column 2 through the screw motor 10 to transport the cement bag to the ground. Finally, open the side plate 5 and use the rotation function of the hinge 16 to rotate the side plate 5 outward around the edge of the support plate 4 so that the worker can move the cement bag from the support plate 4 to the ground.
