Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically a material lifting device for building engineering. Background Technology
[0002] As construction projects progress and buildings grow taller, it becomes necessary to transport large quantities of building materials to higher floors. This requires the use of lifting platforms, which are multi-functional lifting and unloading machinery. They are generally divided into fixed and mobile types. In use, trolleys are typically placed directly on the platform for vertical lifting.
[0003] Existing lifting platforms are just simple platforms. When a trolley is pushed onto the lifting platform, it is often placed directly on the platform. When the platform rises to a relatively high position, it will shake. At this time, because the wheels at the bottom of the trolley are not fixed, it is easy to roll and spill materials out of the trolley.
[0004] The patent document with publication number CN215160588U discloses a material lifting device for construction engineering. The component for locking the wheels can be operated in one step. Pressing the outer contact block unlocks the device, and releasing the outer contact block locks it back in. The structure is more simplified, the operation is more convenient, and the locking and unlocking speed is faster. Compared with the existing friction lock, the direct interception by the horizontal locking arm has better locking stability and further reduces the possibility of damage to the wheel body caused by the clamping lock.
[0005] However, this material lifting device for construction engineering is more suitable for lifting and lowering trolleys. When lifting and lowering ordinary building materials, it can cause problems. Directly placing building materials may damage the original equipment parts, thus limiting its applicability. Therefore, it is necessary to propose a material lifting device for construction engineering. Utility Model Content
[0006] The purpose of this utility model is to provide a material lifting device for construction engineering, so as to solve the problem of loading and lifting building materials mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a material lifting device for construction engineering, comprising a support frame and a lifting frame disposed on one side of the support frame, wherein a limit mechanism is provided inside the lifting frame and a transmission mechanism is provided on one side of the support frame;
[0008] The limiting mechanism includes a left placement plate, a slide groove, an electric telescopic rod, and a limiting block. The left placement plate is fixedly connected to the bottom of the inner wall of the lifting frame. The slide groove is opened at the bottom of the inner wall of the lifting frame. The electric telescopic rod is set on the inner wall of the lifting frame, and the limiting block is set on one side of the electric telescopic rod.
[0009] Preferably, the inner wall of the chute is provided with a groove that cooperates with the limiting block. After the limiting block is engaged in the inner wall of the groove, it can limit the wheels of the cargo cart.
[0010] Preferably, the transmission mechanism includes a dual-axis motor, a support plate, a take-up reel, a steel cable, a fixing ring, and a movable plate. The dual-axis motor is located on the top of the support frame, the support plate is fixedly connected to the top of the support frame, the take-up reel is located on one side of the support plate, the steel cable is located on one side of the support frame, the movable plate is located on one side of the support frame, and the fixing ring is fixedly connected to the top of the movable plate.
[0011] Preferably, the winding reel is connected to the output end of the dual-axis motor, and the winding reel is used to wind up the steel cable to achieve the purpose of lifting and lowering the movable plate.
[0012] Preferably, a ball bearing is provided on one side of the support plate, and the output shaft of the dual-axis motor is connected to the inner ring of the ball bearing. The support plate mainly supports the output shaft of the dual-axis motor.
[0013] Preferably, one end of the steel cable is connected to the winding reel, and the other end is connected to the fixing ring. The extension length of the steel cable determines the height of the movable plate, which can drive the movable plate to rise and fall.
[0014] Preferably, the lifting frame is equipped with a cargo trolley and a storage plate inside the lifting frame. The storage plate is detachable and can be installed when needed.
[0015] Preferably, the bottom of the shelf is provided with a protrusion, and the left shelf has a groove on one side that mates with the protrusion at the bottom of the shelf. After the shelf is installed, it can be used to load some building materials with the two left shelves, and it can also avoid damage to the bottom limiting mechanism parts.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This material lifting device for construction engineering uses a limiting mechanism to allow a trolley loaded with building materials to be pushed into the lifting frame. The two wheels of the trolley are engaged in the sliding grooves. Finally, the electric telescopic rod is activated, which moves the limiting block to stop the trolley. The limiting block engages in a groove on the inner wall of the sliding groove, thus preventing the trolley from rolling randomly during lifting and lowering, which could lead to accidents. It also allows for easy loading and unloading of the trolley and is simple to operate.
[0018] 2. This material lifting device for construction engineering uses a transmission mechanism to start a dual-shaft motor, which drives a winding reel to wind up the steel cable, thereby raising and lowering a movable plate. A lifting frame is fixedly connected to one side of the movable plate, which can also raise and lower the lifting frame. At this time, the two movable plates fixedly connected to both sides of the lifting frame, together with the support frame, limit the lifting frame, improving the stability during lifting and ensuring the safety of the lifting device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-5 This utility model provides a technical solution: Example
[0027] A material lifting device for construction engineering includes a support frame 1 and a lifting frame 2 disposed on one side of the support frame 1, wherein a limit mechanism is provided inside the lifting frame 2.
[0028] The limiting mechanism includes a left storage plate 201, a slide groove 202, an electric telescopic rod 203, and a limiting block 204. The left storage plate 201 is fixedly connected to the bottom of the inner wall of the lifting frame 2. The slide groove 202 is opened at the bottom of the inner wall of the lifting frame 2. The inner wall of the slide groove 202 has a groove that cooperates with the limiting block 204.

The electric telescopic rod 203 is set on the inner wall of the lifting frame 2, and the limiting block 204 is set on one side of the electric telescopic rod 203. After loading building materials onto the trolley 3, it is pushed into the lifting frame 2. The two wheels of the trolley 3 are respectively inserted into the slide groove 202. The electric telescopic rod 203 drives the limiting block 204 to limit the trolley 3. The limiting block 204 is inserted into the groove on the inner wall of the slide groove 202 to limit the trolley 3. This ensures that the trolley 3 will not roll randomly during the lifting process, which could lead to an accident. It also makes it easy to load and unload the trolley 3. Example
[0029] Based on Embodiment 1, a transmission mechanism is provided on one side of the support frame 1. The transmission mechanism includes a dual-axis motor 101, a support plate 102, a take-up reel 103, a steel cable 104, a fixing ring 105, and a movable plate 106. The dual-axis motor 101 is located at the top of the support frame 1, and the support plate 102 is fixedly connected to the top of the support frame 1. A ball bearing is provided on one side of the support plate 102, and the output shaft of the dual-axis motor 101 is connected to the inner ring of the ball bearing. The support plate 102 mainly supports the output shaft of the dual-axis motor 101. The take-up reel 103 is located on one side of the support plate 102 and is connected to the output end of the dual-axis motor 101. The take-up reel 103 is used to wind up the steel cable 104 to achieve the purpose of raising and lowering the movable plate 106. A steel cable 104 is mounted on one side of the support frame 1. One end of the steel cable 104 is connected to a winding reel 103, and the other end is connected to a fixing ring 105. The extension length of the steel cable 104 determines the height of the movable plate 106, allowing the movable plate 106 to be raised and lowered. The movable plate 106 is mounted on one side of the support frame 1, and the fixing ring 105 is fixedly connected to the top of the movable plate 106. A dual-axis motor 101 drives the winding reel 103 to wind the steel cable 104, thereby raising and lowering the movable plate 106. A lifting frame 2 is fixedly connected to one side of the movable plate 106, allowing the lifting frame 2 to be raised and lowered. At this time, the two movable plates 106 fixedly connected to both sides of the lifting frame 2, together with the support frame 1, limit the movement of the lifting frame 2, improving the stability during raising and lowering. Example
[0030] Based on Embodiment 2, the lifting frame 2 is equipped with a cargo cart 3 and a storage plate 4. The storage plate 4 is detachable and can be installed as needed. A protrusion is provided at the bottom of the storage plate 4, and a groove is provided on one side of the left storage plate 201 to mate with the protrusion at the bottom of the storage plate 4. After the storage plate 4 is installed, it can be used with the two left storage plates 201 to load some building materials, and it can also prevent damage to the bottom limiting mechanism parts. By inserting the storage plate 4 into the inner wall of the groove on one side of the left storage plate 201, the storage plate 4 can be fixed. After the storage plate 4 is installed, it can be used with the two left storage plates 201 to easily load and lift ordinary building materials, thus broadening its application range.
[0031] Working principle:
[0032] First, through the transmission mechanism, the dual-axis motor 101 is started, which drives the winding reel 103 to wind the steel cable 104, thereby driving the movable plate 106 to rise and fall. The movable plate 106 is fixedly connected to the lifting frame 2 on one side, which can drive the lifting frame 2 to rise and fall. At this time, the two movable plates 106 fixedly connected to both sides of the lifting frame 2, together with the support frame 1, limit the lifting frame 2, improve the stability during lifting and fall, and ensure the safety of the lifting device.
[0033] Furthermore, through the setting of the limiting mechanism, after the cargo trolley 3 is loaded with building materials, it can be pushed into the lifting frame 2. The two wheels of the cargo trolley 3 are respectively locked into the slide groove 202. Finally, the electric telescopic rod 203 is activated, which drives the limiting block 204 to limit the cargo trolley 3. The limiting block 204 is locked into the groove on the inner wall of the slide groove 202, thus limiting the cargo trolley 3 and ensuring that the cargo trolley 3 will not roll randomly during the lifting process, which could lead to an accident. It also makes it easy to load and unload the cargo trolley 3, and the operation is simple.
[0034] Furthermore, by inserting the storage plate 4 into the inner wall of the slot on one side of the left storage plate 201, the storage plate 4 can be fixed. After the storage plate 4 is installed, it can be used with the two left storage plates 201 to easily load and lift ordinary building materials, making the application range wider and the practicality stronger.
