Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, specifically a heavy object hoist suitable for indoor use. Background Technology
[0002] A hoist is a large mechanical device that transports goods by changing their potential energy, such as a mine hoist or a dam hoist. Broadly speaking, elevators, overhead cranes, winches, trolleys, cranes, and gate hoists can all be called hoists. Hoists generally refer to large mechanical devices with high power and strong lifting capacity. The transportation process is completed by using a power machine to drive a flexible steel wire rope and the transported goods up and down. The steel wire rope is an indispensable and important component of lifting machinery, and the main types include phosphated coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, and bright steel wire rope, etc.
[0003] Traditional methods require manual handling of goods onto the hoist before lifting operations can begin, which is inefficient and time-consuming. Furthermore, due to the height of the hoist, even a slight sway can cause significant instability when the goods are lifted to a high position, posing a risk of the hoist tipping over. Utility Model Content
[0004] The purpose of this invention is to provide a heavy-duty lifting machine suitable for indoor use, which aims to solve the problems of inconvenient operation and the risk of tipping over when goods are lifted to a high place in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: The indoor heavy lifting machine includes a movable base, a lifting and lowering assembly extending in the vertical direction and perpendicularly arranged on the movable base, and a movable carrier assembly detachably connected to the movable base.
[0006] The front side of the mobile base has a groove with the opening facing forward. The mobile carrier assembly carries the goods and moves into the groove. The mobile base and the mobile carrier assembly can be fixedly connected relative to each other by the locking assembly.
[0007] The lifting and lowering assembly includes a telescopic assembly extending in the vertical direction and a lifting assembly disposed on the telescopic assembly. The lifting assembly is capable of lifting the goods located in the groove.
[0008] The telescopic component is vertically arranged with the movable base and the height of the lifting component can be adjusted.
[0009] Preferably, the telescopic assembly includes a telescopic device extending in the vertical direction, a plurality of sleeves extending in the vertical direction, and a slide rod extending in the vertical direction and slidably inserted into the sleeves.
[0010] The lifting assembly is provided with a connecting rod extending in the left and right direction. Both ends of the connecting rod are fixed with connecting plates. The front and rear sides of each connecting plate are fixedly connected to two adjacent sliding rods. The lifting assembly is installed at the end of the movable section of the telescopic device, so that when the telescopic device drives the lifting assembly to extend or retract, it can also drive the sliding rods to move up and down along the sleeve tube through the connecting rods and connecting plates.
[0011] Preferably, the lifting assembly includes an electric hoist fixed to the top of the movable section of the telescopic device and a crossbar that extends in the left-right direction and moves up and down in the up-down direction.
[0012] The output end of the electric hoist is fixed with a chain;
[0013] The telescopic device has a mounting base fixed at the end of its movable section, the electric hoist is mounted on the mounting base, and the connecting rod is fixed on the mounting base.
[0014] The other end of the chain is fixedly connected to the crossbar, and lifting components are fixed at both ends of the crossbar, so that the lifting components can be guided up and down along the sleeve tube.
[0015] A plug is fixed to the front side of the crossbar. The plug is adapted to the mobile carrier assembly to lift the goods on the mobile carrier assembly.
[0016] Preferably, the lifting component includes two L-shaped plates spaced apart from each other, an upper auxiliary wheel rotating between the two L-shaped plates, and a lower auxiliary wheel rotating between the two L-shaped plates;
[0017] The upper auxiliary wheel rolls against the rear side of the sleeve, and the lower auxiliary wheel rolls against the front side of the sleeve.
[0018] Preferably, the mobile vehicle assembly includes a mobile trolley and a pallet placed on the mobile trolley;
[0019] The tray has a through slot with the opening facing downwards, so that the insertion rod can be inserted into the through slot of the tray;
[0020] The locking component is mounted on the mobile trolley, and the mobile base has a through hole. The locking component passes through the through hole and is adapted to the mobile trolley to achieve a relatively fixed connection between the mobile trolley and the mobile base.
[0021] Preferably, the locking assembly includes threaded grooves formed on the left and right side walls of the mobile trolley and bolts that are threaded to fit the threaded grooves;
[0022] The bolt passes through the through hole and is threaded into the threaded groove.
[0023] Preferably, a push rod is fixed to the rear side of the sleeve.
[0024] Preferably, a protective plate is fixed to the upper end of the slide bar.
[0025] The beneficial effects are: 1. Once the mobile trolley carrying the goods is moved into the groove of the mobile base, the trolley can be connected to the mobile base. Subsequently, the lifting component drives the pallet to move up and down, realizing the lifting and lowering operation of the goods. In this way, construction workers do not need to manually move the goods to the vicinity of the mobile base, greatly reducing labor intensity. At the same time, the goods are lifted by the pallet, which is more stable during the lifting process and effectively avoids the risk of the goods tilting or falling.
[0026] 2. During use, the telescopic component can be extended to the indoor roof and connected to the indoor roof through the protective plate to fix the position of the device. After fixing, the goods can be lifted, so that the device can be used stably when lifting the goods and will not tilt or tip over.
[0027] 3. When the mobile trolley is fitted with the groove of the mobile base, the mobile trolley can increase the weight of the base so that the goods can be lifted stably. Attached Figure Description

[0034] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0035] like Figures 1-5 As shown, an indoor heavy-duty lifting machine is mainly used to transport goods to the groove of the mobile base 1 via a mobile trolley 301. Then, the mobile trolley 301 and the mobile base 1 are adapted to each other to increase the weight of the mobile base 1 and prevent it from tipping over. Then, the telescopic component 201 is extended to the indoor roof and connected to the indoor roof through a protective plate. After the device is fixed, it can lift the goods placed on the support pallet 302 without the need for manual handling by construction personnel, and it can also improve stability during the lifting process.
[0036] In this embodiment, the indoor heavy lifting machine includes a mobile base 1, a lifting and lowering assembly extending in the vertical direction and perpendicularly arranged on the mobile base 1, and a mobile carrier assembly 3 detachably connected to the mobile base 1. The lifting and lowering assembly is used to adjust the height so as to lift the goods, while the mobile carrier assembly 3 can transport the goods to the mobile base 1, avoiding manual handling by construction personnel.
[0037] like Figures 1-3 and Figure 5 As shown, the goods are placed in the mobile carrier assembly 3 and then transported to the mobile base 1. The front side of the mobile base 1 has a groove with the opening facing forward. The mobile carrier assembly 3 carries the goods and moves into the groove. The mobile base 1 and the mobile carrier assembly 3 can be fixedly connected relative to each other by the locking assembly. After being fixed relative to each other, the mobile base 1 can be lifted by the lifting and lowering assembly.
[0038] Specifically, the mobile carrier assembly 3 includes a mobile trolley 301 and a support tray 302 placed on the mobile trolley 301. In this embodiment, the structure and principle of the mobile trolley 301 are existing technologies and will not be described in detail here. The support tray 302 has a through slot with the opening facing downwards, so that the insertion rod 12 can be inserted into the through slot of the support tray 302. After the goods are placed on the support tray 302, the construction personnel can transport them to the vicinity of the mobile base 1 through the mobile trolley 301. Then, the mobile trolley 301 is inserted into the groove of the mobile base 1. Then, the mobile trolley 301 and the mobile base 1 are relatively fixedly connected by the locking assembly, so that the mobile trolley 301 and the mobile base 1 are spliced into one piece to increase the counterweight and make the lifting more stable.
[0039] like Figure 5 As shown, the locking component is mounted on the mobile trolley 301, and the mobile base 1 has a through hole. The locking component passes through the through hole and is adapted to the mobile trolley 301, so that the mobile trolley 301 and the mobile base 1 are relatively fixedly connected.
[0040] Specifically, the locking assembly includes threaded grooves 1301 on the left and right side walls of the mobile trolley 301 and bolts 1302 that are threaded to the threaded grooves 1301. When the mobile trolley 301 is inserted into the groove of the mobile base 1, the bolts 1302 can be passed through the through holes and threaded to the threaded grooves 1301. After the bolts 1302 are installed, the mobile trolley 301 and the mobile base 1 are considered as one unit.
[0041] like Figure 1 and Figure 2 As shown, after the mobile trolley 301 is fixed relative to the mobile base 1, the protective plate 5 can be raised by the telescopic lifting assembly and connected to the indoor roof. In this embodiment, the protective plate 5 is connected to the roof frame by bolts. The structure and principle of the connection between the protective plate 5 and the roof frame are existing technologies and will not be described in detail here. After the connection is completed, the stability of the device can be improved.
[0042] Specifically, the lifting and lowering assembly includes a telescopic component 2 extending in the vertical direction. The telescopic component 2 is perpendicular to the movable base 1 and can adjust the height of the lifting component 4.
[0043] The telescopic assembly 2 includes a telescopic device 201 extending in the vertical direction, several sleeves 202 extending in the vertical direction, and sliding rods 203 extending in the vertical direction and slidably inserted into the sleeves 202. In this embodiment, the telescopic device 201 is an electric telescopic rod or a hydraulic telescopic rod. The structure and principle of the electric telescopic rod or the hydraulic telescopic rod are existing technologies and will not be described in detail here. The lifting assembly 4 is provided with a connecting rod 6 extending in the left and right direction. Both ends of the connecting rod 6 are fixed with connecting plates 7. The front and rear sides of each connecting plate 7 are fixedly connected to two adjacent sliding rods 203. After the telescopic device 201 is started, it can move up and down. When the telescopic device 201 moves up and down, it can also drive the sliding rods 203 to move up and down along the sleeves 202 through the connecting rods 6 and the connecting plates 7 to achieve lifting stability.
[0044] A protective plate 5 is fixed to the upper end of the slide bar 203.
[0045] like Figure 1 and Figure 2 As shown, the lifting and lowering assembly also includes a lifting component 4 located at the end of the movable section of the telescopic device 201. The lifting component 4 can lift the goods located in the groove. During the lifting and lowering process of the telescopic device 201, it can drive the lifting component 4 to move up and down to adjust the lifting height.
[0046] Specifically, the lifting assembly 4 includes an electric hoist 402 fixed to the top of the movable section of the telescopic device 201 and a crossbar 403 extending in the left-right direction and rising and falling in the up-down direction. In this embodiment, the structure and principle of the electric hoist 402 are existing technologies and will not be described in detail here. A chain 9 is fixed to the output end of the electric hoist 402; a mounting base 10 is fixed to the end of the movable section of the telescopic device, and the electric hoist 402 is mounted on the mounting base 10. The connecting rod 6 is fixed to the mounting base 10; the other end of the chain 9 is fixedly connected to the crossbar 403. When the telescopic device 201 is in the lifting position... When lowered, the mounting base 10 and the electric hoist 402 can be raised and lowered together. At the same time, the connecting rod 6 and the connecting plate 7 will also rise and fall with the sliding rod 203. Lifting components are fixed at both ends of the crossbar 403, so that the lifting components can be guided up and down along the sleeve tube 202. The front side of the crossbar 403 is fixed with the insertion rod 12. When the moving trolley 301 moves into the groove, the insertion rod 12 can be matched with the pallet 302. Then the electric hoist 402 is started, and the pallet 302 and the goods on the pallet 302 can be lifted through the crossbar 403 and the insertion rod 12.
[0047] The lifting component includes two L-shaped plates 1101 spaced apart from each other, an upper auxiliary wheel 1102 rotating between the two L-shaped plates 1101, and a lower auxiliary wheel 1103 rotating between the two L-shaped plates 1101. The upper auxiliary wheel 1102 rolls against the rear side of the sleeve tube 202, and the lower auxiliary wheel 1103 rolls against the front side of the sleeve tube 202. During the lifting process, the upper auxiliary wheel 1102 and the lower auxiliary wheel 1103 can be fixed against the sleeve tube 202 to achieve the purpose of guiding the lifting. Moreover, through the guidance of the upper auxiliary wheel 1102 and the lower auxiliary wheel 1103 and the sleeve tube 202, the crossbar 403 and the insert rod 12 will not tilt during the lifting process.
[0048] like Figures 1-4 As shown, a push rod 14 is fixed to the rear side of the sleeve tube 202. The push rod 14 is provided so that the device can be moved by the construction personnel when it is not in use. Rollers are provided under the moving base 1 and the moving trolley 301 so that the moving base 1 and the moving trolley 301 can be moved.
[0049] Working principle: In use, the movable base 1 is moved to the area to be lifted. Then, the telescopic device 201 is activated. When the telescopic device 201 is raised and lowered, it can drive the mounting base 10 and the electric hoist 402 to rise and fall together. At the same time, the connecting rod 6 and the connecting plate 7 will also rise and fall with the sliding rod 203. Then, the protective plate 5 is connected to the indoor roof to improve the stability of the device. Meanwhile, the construction personnel push the mobile trolley 301 to carry goods (in this embodiment, the goods can be steel). The trolley 301 for transporting goods is inserted into the groove of the mobile base 1, and the bolt 1302 is passed through the through hole and threaded into the threaded groove 1301. After the bolt 1302 is installed, the trolley 301 and the mobile base 1 are considered as one unit. Then the electric hoist 402 is started, which lifts the pallet 302 and the goods on the pallet 302 through the crossbar 403 and the insert rod 12. After the goods are lifted, the pallet 302 can be placed back on the trolley 301 so that the construction personnel can transport goods again.
[0050] After use, the protective plate 5 can be removed from the roof and then retracted via the telescopic device 201 for lifting and use.
[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
