Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting devices, in particular to a concrete construction lifting box. Background Art
[0002] Concrete is needed when constructing low-rise buildings. The transportation and supply of concrete is an important link. In the construction of low-rise buildings, concrete is usually transported by manual lifting or by using a lifting box.
[0003] The prior art patent document with publication number CN219885551U provides a concrete lifting device, which engages a storage box with a fixed frame, drives the screw rod to rotate through a power device, and causes the slider to move vertically due to the setting of the spring telescopic rod and the roller. The fixed frame is driven to rise by the spring telescopic rod and the support rod. When it rises to the arc section of the track, the moving track of the roller changes, so that the spring telescopic rod is released along the track, and the fixed frame moves toward the arc section, so that the storage box reaches the feet of the construction workers. After the storage box is manually removed, the whole device is reset and the next storage box is lifted. After the next storage box arrives, the used storage box is reset to the fixed frame and waits for reloading, so that the lifting work is more efficient, and thus the overall construction efficiency is higher.
[0004] Although the above-mentioned prior art uses a lifting device to lift the storage box to facilitate people's construction, the device moves through pulleys when moving. After moving to the designated position and parking, the parking is not stable enough and is easy to shift, which affects the use during the construction process and cannot meet people's needs. Therefore, we need a concrete construction lifting box. Utility Model Content

[0024] The stabilizing assembly 2 includes a fixing block 201, and a threaded hole 202 is formed on the outer wall of the fixing block 201, a screw rod 203 is threadedly connected to the inner wall of the threaded hole 202, and one end of the screw rod 203 is fixedly connected to a mounting handle 204, the outer wall of the screw rod 203 is fixedly connected to a limiting plate 205, and one end of the screw rod 203 is fixedly connected to a ground nail 206, the outer wall of the screw rod 203 is threadedly connected to a supporting foot 207, and the bottom of the supporting foot 207 is fixedly connected to an anti-slip pad 208;
[0025] The lifting assembly 4 includes a reduction motor 401, and the output shaft of the reduction motor 401 is fixedly connected to a screw rod 402 through a coupling. The outer wall of the screw rod 402 is threadedly connected to a moving block 403, and the outer wall of the moving block 403 is provided with a threaded groove 404. The inner wall of the moving block 403 is slidably connected to a long rod 405.
[0026] Through the above technical scheme, after the device is moved to the designated position and parked by the universal wheel 5, the screw rod 203 can be rotated by rotating the installation handle 204, so that the support foot 207 moves down, and the support foot 207 drives the anti-skid pad 208 to move down and contact the ground, thereby enhancing stability. If it is a muddy ground, the support foot 207 can be threadedly removed, and the screw rod 203 can be rotated by rotating the installation handle 204, so that the ground nail 206 moves down and extends into the mud, thereby enhancing stability, ensuring the stability of the device when parked, avoiding the occurrence of offset phenomenon, and meeting people's needs. By starting the reduction motor 401, the moving block 403 can be moved up and down, thereby driving the barrel body 10 for storing concrete to rise and fall, thereby accelerating the construction efficiency. The barrel body 10 is placed in the placement groove 9 of the foam block 8 of the box body 7, and the foam block 8 limits the barrel body 10, so that the barrel body 10 is placed more stably and is not easy to shake during the lifting process.
[0027] Specifically, a universal wheel 5 is installed at the bottom of the base 1, and a fixed handle 6 is fixedly connected to the top of the base 1, the outer wall of the moving block 403 is fixedly connected to the box body 7, and a foam block 8 is arranged inside the box body 7, and a placement groove 9 is opened on the outer wall of the foam block 8, and a barrel body 10 is arranged inside the box body 7.
[0028] Through the above technical scheme, the fixed handle 6 is used to push the device to move, the outer wall of the foam block 8 fits with the inner wall of the box body 7, which is convenient for the placement of the foam block 8. The placement groove 9 of the foam block 8 is opened according to the size of the barrel body 10. If the barrel body 10 of different sizes is replaced, the placement groove 9 of the corresponding size can be opened on the foam block 8 to meet the use of barrel bodies 10 of different sizes.
[0029] Specifically, the number of the fixing blocks 201 is four, and two fixing blocks 201 form a group. The two groups of fixing blocks 201 are symmetrically arranged with the mid-perpendicular line of the base 1 as the symmetry axis.
[0030] Through the above technical solution, by providing four fixing blocks 201 at four corners, when in use, the four supporting legs 207 can well support the device, thereby enhancing stability.
[0031] Specifically, the fixing block 201 forms a threaded structure with the screw rod 203 through the threaded hole 202, and one end of the screw rod 203 extends into the threaded hole 202 for connection.
[0032] Through the above technical solution, the connection effect between the fixed block 201 and the threaded hole 202 and the screw 203 is strengthened, the threads on the screw 203 match the threads on the fixed block 201, and the threads on the screw 203 match the threads on the inner wall of the support foot 207, so that the support foot 207 can be threadedly installed on the screw 203.
[0033] Specifically, the fixed frame 3 forms a rotating structure through the reduction motor 401 and the screw rod 402 , and one end of the reduction motor 401 passes through the fixed frame 3 and is connected to the screw rod 402 .
[0034] Through the above technical solution, the connection effect between the fixed frame 3 and the reduction motor 401 and the screw rod 402 is strengthened. After the reduction motor 401 is started, the screw rod 402 can be driven to rotate well. A bearing is provided at one end of the screw rod 402. When the screw rod 402 rotates, it relies on the bearing to rotate more stably.
[0035] Specifically, the moving block 403 forms a threaded structure with the screw rod 402 through the threaded groove 404, and one end of the screw rod 402 extends into the threaded groove 404 for connection.
[0036] Through the above technical solution, the connection effect between the moving block 403, the threaded groove 404 and the screw rod 402 is strengthened, the thread on the screw rod 402 matches the thread in the threaded groove 404, and a groove is opened on the moving block 403. The inner wall of the groove matches the outer wall of the long rod 405. When the moving block 403 moves, it relies on the groove to move on the long rod 405 more stably.
[0037] Specifically, there are multiple placement grooves 9 , and the multiple placement grooves 9 are arranged on the foam block 8 at equal distances.
[0038] Through the above technical solution, by opening a plurality of placement grooves 9, it is convenient to place a plurality of barrels 10, and by providing a plurality of barrels 10, more concrete can be transported.
[0039] When in use, first connect the device to an external power source, and the external power source supplies power to the device. After the device is moved to a designated position and parked by the universal wheel 5, the screw rod 203 can be rotated by rotating the mounting handle 204 to move the support foot 207 downward, and the support foot 207 drives the anti-skid pad 208 downward to contact the ground. The setting of the anti-skid pad 208 enhances the anti-skid ability. The stability of the device is enhanced by the support of the four supporting feet 207. If the ground is muddy, the supporting feet 207 can be removed from the thread to expose the ground nail 206. The screw rod 203 can be rotated by rotating the mounting handle 204 to move the ground nail 206 downward and extend into the mud, thereby enhancing the stability and ensuring the stability of the device when parked. The occurrence of the offset phenomenon is avoided and people's needs are met. When transporting concrete, the concrete is poured into the barrel body 10, and the barrel body 10 is placed in the placement groove 9 of the foam block 8 of the box body 7. The foam block 8 limits the barrel body 10 to prevent the barrel body 10 from shaking. By starting the reduction motor 401, the screw rod 402 is driven to rotate, so that the moving block 403 moves up, the moving block 403 drives the box body 7 to move up, and the box body 7 drives the barrel body 10 to move up to the required position. When descending, by starting the reduction motor 401, the moving block 403 drives the box body 7 to move down, and the box body 7 drives the barrel body 10 to move down. This completes all the work. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
