Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a safe and anti-falling material lifting device for building decoration. Background Art

[0002] A building renovation and decoration material lifting device is a type of equipment specifically designed for vertical material transportation in the building renovation and decoration industry. This device is typically used to address the challenges of material handling on-site. By vertically lifting materials from the ground or other low areas to the required height, it improves construction efficiency and reduces worker workload.

[0003] After searching, a utility model patent with Chinese patent publication number CN218201976U discloses a lifting device for building decoration and decorative materials, which relates to the technical field of lifting devices for building decoration and decorative materials. Specifically, the lifting device comprises a flat plate, the upper surface of which is fixedly connected to a fixed shell by fine screws. The lower portion of the fixed shell is provided with an electric motor, the tangent line of the outer surface of the circumference of the wire wheel on one side of the motor coincides with the center line of the hanger, and the rotating shaft of the motor is provided with a wire wheel, the outer surface of which is wound with steel wire. The lifting device for building decoration and decorative materials, through the arrangement of the electric motor, the cargo hold, and the steel wire, controls the direction of the motor by controlling the motor control switch during use, causing the wire wheel to wind or release the steel wire, thereby causing the steel wire to pull the cargo hold and the slide to climb up or descend along the slide, thereby lifting or lowering the cargo hold, achieving the purpose of efficiently lifting the decorative materials.

[0004] After searching the above patent, it was found that the device dealt with material lifting, but failed to prevent the cargo hold from falling. During the lifting process, if for some reason, such as wire breakage, motor failure or control switch failure, the cargo hold may lose support and cause the cargo hold to fall accidentally, which will not only damage the materials, but also cause serious injuries to the construction workers below.

DETAILED DESCRIPTION

[0021] 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 the embodiments.

[0022] Reference Figure 1-4A material lifting device for building decoration and decoration with safety and anti-falling properties includes a bracket 001, two roller bodies 102 are rotatably connected between the inner walls on both sides of the bracket 001, two sprockets 103 are fixedly connected to the side walls of the roller body 102, and a chain 104 is commonly provided on the outside of the two corresponding sprockets 103, a carrying frame 114 is provided between the inner walls on both sides of the bracket 001, notches 108 are provided on the inner walls on both sides of the bracket 001, and a plurality of card slots 109 are equidistantly provided on the inner walls of the notch 108, and the side walls of the carrying frame 114 are fixedly connected to the side walls of the chain 104; two plates 002, the two plates 002 are respectively arranged on both sides of the carrying frame 114, the plates 002 are slidably connected to the notch 108, the side walls of the plates 002 are provided with grooves 201, and the inner part of the grooves 201 is slidably connected. There is a block 202 in a dynamic connection, and the upper side wall of the block 202 is inclined. The block 202 is slidably connected to the slot 109. A spring 203 is fixedly connected between the side wall of the block 202 and the inner wall of the groove 201. The operator places the material inside the carrier frame 114, and the roller body 102 drives the sprocket 103 to rotate and drives the chain 104, so that the chain 104 drives the carrier frame 114 to lift. During the lifting process of the carrier frame 114, the plate 002 slides inside the slot 108, and at the same time, the block 202 slides to the corresponding slot 109 through the elasticity of the spring 203. During the continuous upward sliding of the plate 002, the inclined wall of the block 202 contacts the upper side of the corresponding slot 109, so that the block 202 automatically slides to the inside of the groove 201.

[0023] A plurality of universal wheels 101 are provided at the lower end of the bracket 001 , and the plurality of universal wheels 101 are distributed in a rectangular array. The plurality of universal wheels 101 facilitate movement of the bracket 001 .

[0024] Two gears 105 are rotatably connected to the inner side wall of the bracket 001. The side wall of the gear 105 is fixedly connected to the end of the roller body 102. A belt 106 is commonly provided on the outside of the two gears 105. When one of the gears 105 rotates, the belt 106 drives the other gear 105 to rotate, so that the two roller bodies 102 rotate at the same time.

[0025] A motor 107 is fixedly connected to the side wall of the bracket 001 , and the motor 107 is fixedly connected to the side wall of one of the gears 105 , and the motor 107 drives one of the gears 105 to rotate.

[0026] Slide grooves 110 are provided inside both sides of the bracket 001, and a movable plate 111 is slidably connected inside the slide groove 110. A plurality of top blocks 112 are equidistantly provided on the side walls of the movable plate 111. The top blocks 112 are slidably connected to the card slot 109. When the supporting frame 114 is lifted to a certain height and the items are taken out, the movable plate 111 drives the top block 112 to slide, and pushes the card block 202 that slides into the card slot 109 into the groove 201, and the multiple card slots 109 are blocked by the multiple top blocks 112.

[0027] Hydraulic cylinders 113 are fixedly connected to both sides of the bracket 001. The output ends of the hydraulic cylinders 113 are fixedly connected to the side walls of the movable plate 111. The hydraulic cylinders 113 push or pull the movable plate 111 to slide horizontally.

[0028] In the present invention, the operator places the material inside the carrying frame 114, drives one of the gears 105 to rotate through the motor 107, and drives the other gear 105 to rotate through the provided belt 106, so that the two rollers 102 rotate at the same time. At the same time, the roller 102 drives the sprocket 103 to rotate and drives the chain 104, so that the chain 104 lifts the carrying frame 114 to the required height, thereby facilitating the lifting of the material.

[0029] During the lifting process of the supporting frame 114, the plate 002 slides inside the slot 108, and at the same time, the block 202 slides into the corresponding slot 109 through the elasticity of the spring 203. When the plate 002 continues to slide upward inside the slot 108, the inclined wall of the block 202 contacts the upper side of the corresponding slot 109, so that the block 202 automatically slides into the groove 201. The cooperation between the block 202 and the slot 109 prevents the supporting frame 114 from accidentally falling during the lifting process.

[0030] When the carrying frame 114 is lifted to a certain height and the items are taken out, the movable plate 111 drives the top block 112 to slide, and pushes the block 202 that has slid into the slot 109 into the groove 201. The multiple slots 109 are blocked by the multiple top blocks 112, and the roller body 102 rotates in the opposite direction, so that the chain 104 drives the carrying frame 114 to slide downward and reset.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
