Description

Technical Field

[0001] This utility model relates to the field of elevators, and in particular to a counterweight device for elevators. Background Technology

[0002] In a hoist, the carrying unit needs to move up and down. In order to reduce the load on the motor, a counterweight (or counterweight) mechanism is usually installed. The weight of the counterweight device is generally the weight of the carrying unit itself plus about half of the load capacity. This can greatly reduce the load on the main unit when the hoist is running, while improving stability and safety.

[0003] A conventional counterweight device typically consists of two parts: a counterweight frame and counterweight blocks. The counterweight frame is a rectangular box into which counterweight blocks are placed. The weight of the counterweight device is adjusted by changing the number of counterweight blocks. This design is advantageous because it can use materials such as concrete as counterweight blocks, saving costs. However, it occupies a large space, has a relatively complex structure, and is inconvenient to disassemble. Utility Model Content

[0004] To solve the above problems, this utility model provides a counterweight device for a lifting platform. It has a simple structure, is easy to manufacture and disassemble, and is very compact, which saves a lot of space, making it especially suitable for scenarios with limited space.

[0005] According to one aspect of the present invention, a counterweight device for a lifting platform is provided, comprising: main body; Screws, at least two sets of vertical screws are disposed on the top of the main body; The counterweights are stacked and placed on top of the main body and fitted over the outside of each set of screws; Nuts, a plurality of said nuts, are respectively mounted on each of said screws and press against the top of said counterweight block at the top of each stack.

[0006] In some embodiments, the main body is composed of multiple vertical iron plates assembled side by side. Its advantage lies in describing the specific structural composition of the main body.

[0007] In some embodiments, each counterweight has multiple through holes, and each set of screws passes through each hole of each stack of counterweights. The advantage is that the structure of the counterweights is further described.

[0008] In some embodiments, each set of the screws has two screws, and each counterweight has two bushings. The advantage is that the number of bushings in each set of screws and each counterweight is described as equal, and can be set to other numbers as needed.

[0009] In some embodiments, at least one upper connecting block is mounted on the top of the main body, with each upper connecting block located between adjacent sets of screws. This is advantageous because the upper connecting blocks on the main body can be used to connect the suspension mechanism of the elevator as needed.

[0010] In some embodiments, multiple vertically arranged side connecting blocks are installed on both sides of the main body. This is advantageous because the side connecting blocks on the main body can be used to connect the suspension mechanism of the elevator as needed. Attached Figure Description

[0011] Figure 1 This is a structural schematic diagram of a counterweight device for an elevator according to one embodiment of the present invention; Figure 2 for Figure 1 A schematic diagram of the relevant structure of the main body shown; Figure 3 for Figure 1 The diagram shows the structure of the counterweight. Figure 4 This is a structural schematic diagram of a counterweight device for a lifting platform, representing another embodiment of the present invention.

[0012] In the diagram: 1. Main body; 2. Screw; 3. Counterweight; 4. Nut; 5. Iron plate; 6. Sleeve hole; 7. Upper connecting block; 8. Side connecting block. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] like Figure 1-3 As shown, a lifting counterweight device of the present invention includes a main body 1, which is composed of multiple vertically arranged iron plates 5 assembled and connected in parallel.

[0015] Multiple stacked counterweights 3 can be easily installed and removed from the top of the main body 1. Specifically, at least two sets of vertical screws 2 are provided on the top of the main body 1, generally two in each set. Each stack of counterweights 3 is fitted onto each set of screws 2 and placed on the top of the main body 1. Each counterweight 3 is provided with multiple through holes 6, the same number as the screws 2 in each set, and each screw 2 in each set passes through the through holes 6 on each counterweight 3.

[0016] In addition, each screw 2 is equipped with a nut 4, and each nut 4 is tightened to the top of the top counterweight 3 in a stack of counterweights 3.

[0017] Preferably, at least one upper connecting block 7 is installed on the top of the main body 1, and each upper connecting block 7 is located between adjacent sets of screws 2. The upper connecting block 7 can be used to connect the suspension mechanism of the elevator as needed.

[0018] Preferably, multiple side connecting blocks 8 are installed on both sides of the main body 1, and the side connecting blocks 8 can also be used to connect the suspension mechanism of the elevator as needed.

[0019] When using the counterweight device of this lifting platform, the weight of the counterweight device can be adjusted by installing and removing the counterweight block 3 as needed.

[0020] like Figure 4 As shown, the number of sets of screws 2 and the number of stacks of counterweights 3 can be adjusted appropriately according to actual needs. For example, if three sets of screws 2 and three sets of counterweights 3 are selected, it is often necessary to adjust the distance between each screw 2 in each set and the width of the counterweights 3 to adapt to the size of the main body 1.

[0021] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
