Description

Technical Field

[0001] The utility model relates to the technical field of goods lifting, in particular to a small lifting platform for carrying goods. Background Technique

[0002] The goods lifting platform is a vertical transportation device, mainly used for vertical transportation of goods inside or outside buildings. It is also a hoisting machine, widely used for vertical transportation in logistics systems such as factories and automated warehouses. Usually, various planar transportation devices are also installed as connection devices for transportation lines at different heights.

[0003] For example, the existing patent (Publication No.: CN207192682U) discloses a small elevator for facilitating the transportation of goods. First, hold the handle and push the elevator to the place of use. After adjusting the position of the elevator, then place the goods on the lifting platform, turn on the switch on the control panel, the hydraulic pump squeezes the liquid in the fuel tank into the hydraulic cylinder, the air pressure in the hydraulic cylinder changes to push the telescopic rod to extend outwards, so that the lifting rod is lifted upwards, and the goods are lifted to a certain height.

[0004] However, the above-designed small elevator for facilitating the transportation of goods still has some disadvantages in actual use: Although the above-designed elevator can lift and transport goods in height, most of the elevators designed above are mainly hydraulic structures, making the equipment heavy and large in size, with relatively strict requirements for the installation space. For relatively narrow spaces, it is more inconvenient to install.

[0005] Therefore, we designed a small lifting platform for carrying goods to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a small lifting platform for carrying goods to solve the problems put forward in the above background technique.

[0007] To solve the above technical problems, a small lifting platform for carrying goods provided by the utility model includes

[0008] A goods lifting frame symmetrically provided with two vertically extending tracks;

[0009] Two sprocket assemblies respectively arranged in the corresponding tracks. Each sprocket assembly includes two sprocket bodies arranged vertically and rotatably in the tracks. The two sprocket bodies are driven by a chain; any one of the sprocket bodies is driven by a motor;

[0010] A lifting platform slidably arranged in the tracks, and the lifting platform is connected to the chains of the two sprocket assemblies;

[0011] The shaft portions of every two horizontal sprocket bodies are both connected with a horizontally arranged rotating shaft.

[0012] Furthermore, the lifting platform includes

[0013] two sliding portions, which are arranged in corresponding tracks and connected to the chain;

[0014] a lifting platform, which is connected to the sliding portions and vertically extends outward from within the tracks.

[0015] Furthermore, at least two pulleys are arranged on the sliding portions. The two pulleys are arranged vertically along the extending direction of the tracks. The pulleys will move along with the lifting platform and roll within the tracks, which can not only limit the moving direction of the lifting platform, but also reduce the friction force of the limiting structure, thereby helping to reduce mechanical wear and the electric energy output by the motor, achieving the effect of energy conservation.

[0016] Furthermore, the pulley is at least in point contact with the front side or the rear side of the track.

[0017] Furthermore, the pulley is in point contact with both the front side and the rear side of the track.

[0018] Furthermore, the lifting platform includes a object supporting member and a buffer plate. The object supporting member is fixedly connected to both the C-shaped member and the chain. The buffer plate is located above the object supporting member and connected thereto. A buffer groove is formed at the top of the object supporting member. A T-shaped member is slidably connected in the buffer groove. The top end of the T-shaped member is fixedly connected to the buffer plate. A spring and a damping cylinder are fixedly installed at the bottom of the T-shaped member. The other ends of the spring and the damping cylinder are both arranged on the inner bottom wall of the buffer groove. During the sudden stop or movement of the lifting platform, the lifting platform will generate vibration force and inertia force on the object respectively. At this time, the object drives the buffer plate to move downward, so that the T-shaped member moves downward in the buffer groove and compresses the spring. After the vibration force and inertia force are completely absorbed, the cooperation of the damping cylinder can make the spring slowly rebound, which can avoid the problem that the object jumps and falls from the buffer plate, and improves the stability of the lifting platform.

[0019] Furthermore, there are two groups of buffer grooves. The number of each group of buffer grooves is two, and the two groups of buffer grooves are symmetrically formed at the top of the object supporting member. The setting of multiple buffer grooves means that the buffering effect of the buffer plate can be improved.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. By starting the motor, the motor can drive one of the rotating shafts to rotate, so that the rotating shaft drives the sprocket bodies on both sides to rotate, and then the sprocket bodies can drive the chain to move, thereby enabling the lifting platform to be lifted along the direction set by the track, achieving the effect of lifting heavy objects with large torque. Moreover, this lifting device is small in volume, simple in structure, and convenient to install. Usually, it only needs to be fixed by relying on the wall. It runs smoothly and has a large load capacity;

[0021] 2. During the lifting process of the lifting platform, the pulleys will move along with the lifting platform and roll within the tracks. This not only limits the movement direction of the lifting platform but also reduces the friction of the limiting structure, thereby helping to reduce mechanical wear and the electrical energy output by the motor, achieving an energy-saving effect.

[0022] 3. During the emergency stop or movement of the lifting platform, the lifting platform will generate vibration force and inertial force on the goods respectively. At this time, the goods drive the buffer plate to move downward, causing the T-shaped part to move downward in the buffer groove and compress the spring. After the vibration force and inertial force are completely absorbed, the spring can be slowly rebounded in cooperation with the damping cylinder, which can avoid the problem that the goods jump and fall off the buffer plate, improving the stability of the lifting platform.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-3 , the present utility model provides a technical solution: a small lifting platform for carrying goods, including

[0029] A goods lifting frame 7, with two vertically extending tracks 5 symmetrically arranged;

[0030] Two sprocket assemblies, respectively arranged in the corresponding tracks 5. Each sprocket assembly includes two sprocket main bodies 2, which are arranged vertically and rotatably in the tracks 5, and the two sprocket main bodies 2 are driven by a chain 4; any one of the sprocket main bodies 2 is driven by a motor 6;

[0031] The lifting platform 1 is slidably arranged in the track 5, and the lifting platform 1 is connected to the chain 4 of the two sprocket assemblies;

[0032] The shaft parts of every two transverse sprocket bodies 2 are both connected with a laterally arranged rotating shaft 8;

[0033] The lifting platform 1 includes,

[0034] Two sliding parts, which are arranged in the corresponding tracks 5 and are connected to the chain 4;

[0035] The lifting platform, which is connected to the sliding parts and vertically extends outward from the track 5.

[0036] During specific implementation, place the item to be lifted on the top of the buffer plate 10, turn on the motor 6, so that the drive shaft of the motor 6 drives one of the rotating shafts 8 to rotate, making the rotating shaft 8 drive the sprocket bodies 2 on both sides to rotate, and then the sprocket bodies 2 can drive the chain 4 to move, so that the lifting platform 1 can be lifted along the direction set by the track 5, thus achieving the effect of lifting heavy objects with large torque. Moreover, this lifting device is small in volume, simple in structure and convenient to install. Usually, it only needs to be fixed by relying on the wall, runs stably and has a large load capacity.

[0037] Refer to Figures 1-3 As shown, at least two pulleys 3 are arranged on the sliding part. The two pulleys 3 are arranged vertically along the extending direction of the track 5. The pulley 3 is at least in point contact with the front side or the rear side of the track 5, and the pulley 3 is in point contact with both the front and rear sides of the track 5.

[0038] During specific implementation, on the basis of the above implementation, during the lifting process of the lifting platform 1, the pulley 3 will move with the lifting platform 1 and roll in the track 5, which can not only limit the moving direction of the lifting platform 1, but also reduce the friction force of the limiting structure, thus helping to reduce mechanical wear and the electric energy output by the motor 6, achieving the effect of energy saving.

[0039] Refer to Figures 1-3, the lifting platform 1 includes an object support 9 and a buffer plate 10. The object support 9 is fixedly connected to both the C-shaped member and the chain 4. The buffer plate 10 is located above the object support 9 and is connected. A buffer groove 11 is formed at the top of the object support 9. A T-shaped member 12 is slidably connected in the buffer groove 11. The top end of the T-shaped member 12 is fixedly connected to the buffer plate 10. A spring 13 and a damping cylinder 14 are fixedly installed at the bottom of the T-shaped member 12. The other ends of the spring 13 and the damping cylinder 14 are both arranged on the inner bottom wall of the buffer groove 11. During the sudden stop or movement of the lifting platform 1, the lifting platform 1 will generate vibration force and inertial force on the article respectively. At this time, the article drives the buffer plate 10 to move downward, so that the T-shaped member 12 moves downward in the buffer groove 11 and compresses the spring 13. After the vibration force and inertial force are absorbed completely, the cooperation of the damping cylinder 14 can make the spring 13 rebound slowly, which can avoid the problem that the article jumps and falls off the buffer plate 10, and improves the stability of the lifting platform.

[0040] Refer to Figures 1-3 , there are two groups of buffer grooves 11. The number of each group of buffer grooves 11 is two, and the two groups of buffer grooves 11 are symmetrically arranged at the top of the object support 9. The setting of multiple buffer grooves 11 means that the buffering effect of the buffer plate 10 can be improved.

[0041] In addition, in order to make it more convenient for personnel to remotely control the lifting platform, a signal receiver and a controller can be installed on the motor 6, so that the signal receiver, the controller and the motor 6 are electrically connected, so that personnel can conveniently remotely control the switch and operating state of the motor 6. Since the signal receiver and the controller are prior arts, they will not be described in detail in this specification.

[0042] Working principle: When the lifting platform needs to be used, first connect the motor 6 to an external power supply, then place the article to be lifted on the top of the buffer plate 10, turn on the motor 6, so that the drive shaft of the motor 6 drives one of the rotating shafts 8 to rotate, so that the rotating shaft 8 drives the sprocket bodies 2 on both sides to rotate, and then the sprocket bodies 2 can drive the chain 4 to move, so that the lifting platform 1 can be lifted along the direction set by the track 5, and the effect of lifting heavy objects with large torque can be achieved. In addition, during the lifting process of the lifting platform 1, the pulley 3 will move with the lifting platform 1 and roll in the track 5, which can not only limit the moving direction of the lifting platform 1, but also reduce the friction force of the limiting structure, thus helping to reduce mechanical wear and reduce the electric energy output by the motor 6, achieving the effect of energy saving;

[0043] In addition, during the emergency stop or movement of the lifting platform 1, the lifting platform 1 generates vibration force and inertial force on the article respectively. At this time, the article drives the buffer plate 10 to move downward, so that the T-shaped part 12 moves downward in the buffer groove 11 and compresses the spring 13. After the vibration force and inertial force are completely absorbed, the cooperation of the damping cylinder 14 enables the spring 13 to slowly rebound, which can avoid the problem that the article jumps and falls off the buffer plate 10, and improves the stability of the lifting platform.
