Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight technology, and in particular to a prefabricated elevator counterweight structure. Background Technology

[0002] The counterweight in an elevator balances the car. A traction rope connects the car and the counterweight frame. The friction between the traction rope and the traction sheave on the roof drives the car up and down, balancing its weight. The traction sheave, by distributing the weight difference between the car and the counterweight, causes the car to move up and down. The counterweight is mounted on a fixed frame and connected to the traction rope inside the elevator. The counterweight system is one of the main components of an elevator. The counterweight (also called a counterweight block, balance block, etc.) is currently made of steel plate, cast iron (or die-cast), cement, or composite materials. All are integrally cast, each weighing tens or even hundreds of kilograms, making transportation and installation extremely difficult. Utility Model Content

[0003] In order to overcome the technical defects mentioned in the background art, the purpose of this utility model is to provide a prefabricated elevator counterweight structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A prefabricated elevator counterweight structure includes a frame and a plurality of counterweight blocks stacked sequentially along the height direction on the frame; each layer of the frame has one counterweight block; the frame includes two columns, an upper beam connected to the upper ends of the two columns, and a lower beam connected to the lower ends of the two columns; each of the two columns has a slot arranged along the height direction on one opposite side; the counterweight block includes a housing and a plurality of filler blocks arranged sequentially within the housing; one end of the housing is engaged in one of the slots, and the other end of the housing is engaged in the other slot; both ends of the filler blocks are in contact with the corresponding inner sidewall of the housing, and adjacent filler blocks are in contact with each other.

[0006] By adopting the above technical solution, multiple layers of counterweights are arranged sequentially from bottom to top within the frame. The encapsulation shell of the counterweights is snapped between two uprights, improving the stability and safety of the overall structure. By filling multiple filler blocks inside the encapsulation shell to assemble a single counterweight, processing is convenient, and handling, storage, installation, and disassembly are easier and more convenient, significantly improving installation and disassembly efficiency and reducing costs. It is adaptable to a wider range of scenarios and has stronger compatibility.

[0007] Furthermore, the encapsulation shell includes a first encapsulation cover and a second encapsulation cover. The first encapsulation cover and the second encapsulation cover have the same structure. One end of the first encapsulation cover is engaged in one of the slots, and the other end of the first encapsulation cover is engaged in the other slot, making installation and disassembly more convenient and reducing processing, storage, and transportation costs. The first encapsulation cover and the second encapsulation cover are symmetrically arranged along the central axis of the column, which facilitates the balance of gravity and makes the assembled structure more stable.

[0008] Furthermore, the first encapsulation cover includes two fixing sections and an encapsulation section connecting the two fixing sections. The fixing sections are L-shaped, with one end connected to the bottom of the corresponding slot and the other end tightly abutting the sidewall of the corresponding slot. This increases the compressive strength of the encapsulation section when the filling block compresses it, preventing deformation and detachment of the fixing sections from the slot. The encapsulation section is U-shaped and protrudes from the pillar, increasing the size of the placed filling block to improve its weight and enhance compatibility.

[0009] Furthermore, the length of one end of the fixing segment is less than half the width of the slot, which can save costs.

[0010] Furthermore, the first encapsulation cover also includes a receiving section, which protrudes from the inner side of the lower ends of the two fixing sections and the encapsulation section. The lower surface of the filling block is connected to the upper surface of the receiving section, which facilitates the stacking and alignment of the filling blocks, resulting in a flatter assembly of the counterweight blocks and higher installation efficiency.

[0011] Furthermore, the filling block is provided with an open mounting groove corresponding to the receiving section. The receiving section is located in the mounting groove. The depth of the mounting groove is less than or equal to the thickness of the receiving section, and the width of the mounting groove is equal to the width of the receiving section. This facilitates fixing the filling block and also allows for support connection between two adjacent layers of filling blocks, which helps to reduce the load-bearing strength of the encapsulation shell.

[0012] Furthermore, the column is configured as a channel steel or C-shaped steel structure, and the U-shaped or C-shaped groove of the column serves as the slot, which is simple in structure and easier and faster to process.

[0013] Furthermore, the prefabricated elevator counterweight structure also includes an upper steel plate and a lower steel plate. The lower steel plate is placed on the lower beam, and the lowest counterweight block is placed on the lower steel plate, making the installation more stable. The upper steel plate is placed on the upper surface of the uppermost counterweight block to press it down and prevent the filling blocks inside from shifting and separating during use, thereby improving the overall structural stability and making it safer to use.

[0014] Furthermore, bonding or welding two adjacent filler blocks together can improve stability and make installation and disassembly more convenient and quick.

[0015] Furthermore, the filling block is made of metal, which saves costs while ensuring sufficient self-weight.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] In this invention, multiple counterweights are arranged sequentially from bottom to top within the frame. The encapsulation shell of each counterweight is snapped between two upright columns, improving the stability and safety of the overall structure. By filling multiple filler blocks inside the encapsulation shell to assemble a single counterweight, processing is convenient, and transportation, storage, installation, and disassembly are easier and more convenient, significantly improving installation and disassembly efficiency and reducing costs. Moreover, it is adaptable to a wider range of scenarios and has stronger compatibility. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 The embodiments of this utility model will be described in further detail below.

[0027] A prefabricated elevator counterweight structure 1, such as Figure 1 , Figure 2 As shown, it includes a frame 2 and several counterweights 3 stacked sequentially along the height direction on the frame 2. Each layer of the frame 2 has a corresponding counterweight 3. The frame 2 includes two columns 21, an upper beam 22 connecting the upper ends of the two columns 21, and a lower beam 23 connecting the lower ends of the two columns 21. Each of the two columns 21 has a slot arranged along the height direction on its opposite side. The counterweight 3 includes a housing 31 and a plurality of filler blocks 32 arranged sequentially within the housing 31. One end of the housing 31 is engaged in one of the slots, and the other end of the housing 31 is engaged in another slot. Both ends of the filler blocks 32 are in contact with the corresponding inner sidewall of the housing 31, and adjacent filler blocks 32 are in contact with each other.

[0028] Specifically, multiple counterweights 3 are arranged sequentially from bottom to top within the frame 2. The encapsulation shell 31 of the counterweight 3 is snapped between two columns 21, improving the stability and safety of the overall structure. By filling multiple filler blocks into the encapsulation shell 31 to assemble a counterweight 3, the processing is convenient, and the handling, storage, installation, and disassembly are easier and more convenient, significantly improving installation and disassembly efficiency and reducing costs.

[0029] In some embodiments, please refer to Figure 2 , Figure 3The encapsulation shell 31 includes a first encapsulation cover 311 and a second encapsulation cover 312. The first encapsulation cover 311 and the second encapsulation cover 312 have the same structure. One end of the first encapsulation cover 311 is engaged in a slot, and the other end of the first encapsulation cover 311 is engaged in another slot, making installation and disassembly more convenient and reducing processing, storage, and transportation costs. The first encapsulation cover 311 and the second encapsulation cover 312 are symmetrically arranged along the central axis of the column 21, which facilitates the balance of gravity and makes the assembled structure more stable.

[0030] Preferably, the first encapsulation cover 311 includes two fixing sections 3111 and an encapsulation section 3112 connecting the two fixing sections 3111. The fixing sections 3111 are configured with an L-shaped structure, with one end of the fixing section 3111 connected to the bottom of the corresponding slot, and the other end of the fixing section 3111 tightly attached to the side wall of the corresponding slot. This can improve the compressive strength of the encapsulation section 3112 when the filling block 32 is pressed, and prevent the fixing section 3111 from deforming and detaching from the slot. The encapsulation section 3112 is configured with a U-shaped structure and protrudes from the post 21, which can increase the size of the placed filling block 32 to increase its self-weight and improve compatibility.

[0031] To save costs and reduce weight, and to make handling and installation easier and faster, the length of one end of the fixing section 3111 is less than half the width of the slot, which can save costs. Specifically, the length of one end of the fixing section 3111 can be one-quarter of the width of the slot.

[0032] Preferably, please refer to Figure 2 , Figure 3 The first encapsulation cover 311 also includes a receiving section 3113, which protrudes from the inner side of the lower ends of the two fixing sections 3111 and the encapsulation section 3112. The lower surface of the filling block 32 is connected to the upper surface of the receiving section 3113, which facilitates the stacking and aligning of the filling blocks 32, making the counterweight 3 assembled more evenly and improving the installation efficiency.

[0033] Specifically, the filler block 32 is provided with an open mounting groove corresponding to the receiving section 3113. The receiving section 3113 is located in the mounting groove. The depth of the mounting groove is less than or equal to the thickness of the receiving section 3113, and the width of the mounting groove is equal to the width of the receiving section 3113. This facilitates fixing the filler block 32 and also allows for support connection between two adjacent filler blocks 32, which helps to reduce the load-bearing strength of the encapsulation shell 31.

[0034] In some embodiments, please refer to Figure 2 The column 21 is made of channel steel or C-shaped steel structure. The U-shaped or C-shaped groove of the column 21 serves as a slot, which is simple in structure and makes processing more convenient and faster.

[0035] In some embodiments, please refer to Figure 1The prefabricated elevator counterweight structure 1 also includes an upper steel plate 4 and a lower steel plate 5. The lower steel plate 5 is placed on the lower beam 23, and the lowest counterweight block 3 is placed on the lower steel plate 5, making the installation more stable. The upper steel plate 4 is placed on the upper surface of the uppermost counterweight block 3 to press down the uppermost counterweight block 3 and prevent the filling block 32 inside from being misaligned and separated during use, which can improve the stability of the overall structure and make it safer to use.

[0036] The upper steel plate 4 and the lower steel plate 5 are set to have the same width as the counterweight 3, which makes the overall appearance neater and more aesthetically pleasing, and can also save costs.

[0037] In some embodiments, adjacent filler blocks 32 in the same counterweight 3 can be glued or welded together to improve stability and make installation and disassembly more convenient and quick. Welding, in particular, can be done by spot welding, which is more efficient. Alternatively, inserting retaining blocks between the filler blocks 32 can reduce the gap between adjacent filler blocks 32, resulting in a more stable structure.

[0038] In some embodiments, the filler block 32 is configured as a metal structure, saving costs while ensuring sufficient self-weight. Specifically, the length of the filler block 32 is the same as the spacing between the first encapsulation cover 311 and the second encapsulation cover 312, and the thickness of the filler block 32 is the same as the width of the first encapsulation cover 311, so that multiple filler blocks 32 and the encapsulation shell 31 are stacked flat and stable. The filler block 32 can be configured as a steel plate, cast steel block, cast iron block, or a block made of scrap iron, iron powder, etc., through processes such as casting, hot pressing, cold pressing, stamping, forging, and bonding. This counterweight 3 can effectively reduce costs. The metal block made of scrap iron, iron powder, etc., is about 30% cheaper than the steel plate counterweight 3 and about 20% cheaper than the cast iron (or die-cast) counterweight 3.

[0039] During installation, first install a lower steel plate 5 with the same width as the counterweight block 3 on the lower beam 23. Then, secure the ends of the first encapsulation cover 311 and the second encapsulation cover 312 into the slots of the two columns 21. Next, lay the counterweight filling block 32 flat and assemble it inside the encapsulation shell 31. The filling block 32 and the encapsulation shell 31, as well as the encapsulation shell 31 and the frame 2, must be firmly secured to form one layer of counterweight blocks 3. Then, stack the counterweight blocks upwards layer by layer in the same way. After installing the top layer of counterweight blocks 3, use clamps to press an upper steel plate 4 on top, completing the installation of the entire ladder counterweight system. This method is convenient for transportation and installation, and has greater applicability.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
