Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight technology, and in particular to a novel hybrid cement elevator counterweight block. Background Technology

[0002] Traditional elevator counterweights are mainly made of cast iron. With the rising price of raw materials for cast iron, alternatives are being sought. One existing method for manufacturing elevator counterweights involves mixing scrap iron, cement, sand, and water to create a filler for the counterweight. This filler is then poured into a cast iron shell to obtain a concrete elevator counterweight. However, because a large amount of scrap iron is used, and scrap iron is not easily broken, large pieces of scrap iron end up in the filler. This results in uneven strength and uneven stress distribution within the filler, causing the center of gravity of the elevator counterweight to deviate from the expected value, ultimately affecting the performance of the counterweight. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a new type of hybrid cement elevator counterweight block to solve the technical problem that the scrap iron in the filler is easily unevenly distributed during the filling of existing elevator counterweight blocks, which leads to the center of gravity of the counterweight block deviating from the expected position.

[0004] To achieve the above objectives, this utility model provides a novel hybrid cement elevator counterweight, comprising:

[0005] A housing with an opening at the top and a cover plate that matches the opening;

[0006] At least one filter assembly disposed in the housing for filtering heavy blocks in the filler, the filter assembly having at least one inlet end for filling the filler and at least one outlet end for discharging the filler, the size of the outlet end being smaller than the size of the heavy block, in use, filling the inlet end to concentrate the heavy blocks in the filler at a designated location, thereby balancing the center of gravity of the elevator counterweight.

[0007] As a preferred embodiment of this invention, the filtering component includes:

[0008] A vertical strip is vertically arranged at one end inside the bottom of the housing, and there are multiple vertical strips arranged at intervals between each other;

[0009] A horizontal bar is attached to the surface of a vertical bar at one end. There are multiple horizontal bars that are spaced apart along the length of the vertical bar. The vertical bar and the horizontal bar are interlaced to form a mesh structure with the opening facing upward.

[0010] As a preferred embodiment of this utility model, the horizontal bar is a ring-shaped component.

[0011] As a preferred embodiment of this utility model, the lower end of the cover plate is provided with a positioning flange, which matches the positioning groove opened at the end of the housing opening.

[0012] As a preferred embodiment of this utility model, the upper end of the cover plate is provided with at least one limiting protrusion, which matches the limiting groove opened at the bottom of the housing.

[0013] As a preferred embodiment of this invention, the bottom of the housing has two limiting grooves.

[0014] As a preferred embodiment of this utility model, through grooves are provided on both sides of the housing, and structures for assisting in handling are provided in the through grooves.

[0015] As a preferred embodiment of this utility model, grooves are provided on the front and rear sides of the housing.

[0016] The beneficial effects of this utility model are as follows: By setting a filter component in the shell, this utility model can concentrate and process heavy objects such as scrap iron in the filler, preventing the scrap iron from being scattered randomly in the shell, which would cause the center of gravity of the elevator counterweight to be out of the expected position. In use, the mixed filler is poured into the inlet end of the filter component. Since the size of the outlet end is smaller than the size of the scrap iron, and other flowing materials in the filler are smaller than the scrap iron, only the scrap iron stays in the filter component, ensuring that the center of gravity of the elevator counterweight is in the expected position after filling.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0025] like Figure 1 and Figure 3 As shown, a novel hybrid cement elevator counterweight includes:

[0026] A housing 1 with an opening at the top and a cover plate 2 that matches the opening;

[0027] At least one filter assembly disposed in housing 1 for filtering heavy blocks in filler, the filter assembly having at least one inlet end for filling and at least one outlet end for discharging filler, the size of the outlet end being smaller than the size of the heavy block, in use, filling is poured into the inlet end to make the heavy blocks in the filler concentrated and distributed in a designated position, thereby balancing the center of gravity of the elevator counterweight.

[0028] The above technical solution can ensure that the heavy objects such as scrap iron in the filler are concentrated in the shell 1 during the filling process, preventing the scrap iron from being scattered randomly in the shell 1, which would cause the center of gravity of the elevator counterweight to be out of the expected position. In use, the mixed filler is poured into the inlet end of the filter assembly. The filler leaves the filter assembly through the outlet end and spreads to other positions in the shell 1. Since the size of the outlet end is smaller than the size of the scrap iron, and the other flowing materials in the filler are smaller than the scrap iron, only the scrap iron stays in the filter assembly. After the filling is completed, it is left for a period of time to allow the filler to solidify and fix. Then, the cover plate 2 is placed on top to seal the opening at the top of the shell 1, and the cover plate 2 is welded to the opening.

[0029] It should be noted that the filter components are set up to ensure that the distribution of scrap iron is controllable, thereby preventing the scrap iron from being scattered randomly after the filling material is poured. When only one filter component is set up, the center of the filter component should be as close as possible to the center of gravity to ensure that the center of gravity of the elevator counterweight block is in the expected position after filling. When multiple filter components are set up, it should be ensured that the connection point between the centers of the filter components converges on the center of gravity.

[0030] like Figure 3 As shown, in this embodiment, the filter assembly includes: a vertical strip 10 with one end vertically disposed at the bottom of the inner end of the housing 1, and the vertical strip 10 having a plurality of such strips and being spaced apart from each other; and a horizontal strip 11 with one end attached to the surface of the vertical strip 10, the horizontal strip 11 having a plurality of such strips and being spaced apart along the length direction of the vertical strip 10, the vertical strip 10 and the horizontal strip 11 intersecting to form an upward-facing mesh structure, and the horizontal strip 11 preferably being an annular member.

[0031] The above technical solution can form a mesh-like filter structure to filter the scrap iron in the filler. In addition to being able to form a filter screen, the vertical bars 10 and horizontal bars 11 can also increase the contact area between the counterweight and the filler. This allows the filler to be fixed to the vertical bars 10 and horizontal bars 11 after it clumps together. This can effectively prevent relative displacement between the internal filler and the shell 1 when the elevator counterweight is subjected to external force, prevent the filler from breaking, and thus effectively improve the structural strength.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, the lower end of the cover plate 2 is provided with a positioning flange 3, which matches the positioning groove 4 opened at the end of the opening of the housing 1.

[0033] The above technical solution can easily fix the cover plate 2 to the opening end of the housing 1. By setting the positioning flange 3 and the positioning groove 4, the cover plate 2 can be pre-positioned at the opening end of the housing 1 through their mutual cooperation, so as to prevent relative movement between the two during the welding process.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the upper end of the cover plate 2 is provided with at least one limiting protrusion 5, which matches the limiting groove 6 opened at the bottom of the housing 1; preferably, there are two limiting grooves 6 at the bottom of the housing 1.

[0035] The above technical solution facilitates the bulk transportation of elevator counterweights. By setting the limiting protrusion 5 and the limiting groove 6, the vertically stacked elevator counterweights can be mutually limited to prevent them from shaking during transportation. At the same time, there are two limiting grooves 6 at the bottom of the housing 1, which facilitates the insertion of forklift forks and makes bulk transportation convenient.

[0036] like Figure 1 As shown, in this embodiment, through grooves 7 are provided on both sides of the housing 1, and a structure for assisting handling is provided in the through grooves 7; preferably, the structure for assisting handling is a handle 9 provided in the through groove 7, and grooves 8 are provided on the front and rear sides of the housing 1.

[0037] The above technical solution can help improve the strength of the housing 1. By opening through grooves 7 and grooves 8 on the surface of the housing 1, the deformation resistance of the housing 1 can be effectively improved. The handle 9 can be conveniently operated during handling.

[0038] Working principle: When in use, the mixed filler is poured into the area enclosed between the vertical bar 10 and the horizontal bar 11. Some of the material in the filler leaves the filter component through the gap between the vertical bar 10 and the horizontal bar 11 and spreads to other positions in the shell 1. Since the gap between the vertical bar 10 and the horizontal bar 11 is smaller than the size of the scrap iron, and the other flowing materials in the filler are smaller than the scrap iron, only the scrap iron stays in the area enclosed between the vertical bar 10 and the horizontal bar 11. Continue pouring until the filler overflows the upper opening of the shell 1. After pouring, let it sit for a period of time to allow the filler to solidify and fix. Then, insert the positioning flange 3 at the lower end of the cover plate 2 into the positioning groove 4 at the upper end of the shell 1, thereby sealing the upper opening of the shell 1 with the cover plate 2. Weld the cover plate 2 to the opening, so that the heavy objects such as scrap iron in the filler are concentrated in the shell 1, preventing the scrap iron from being scattered randomly in the shell 1, which would cause the center of gravity of the elevator counterweight to be out of the expected position.

[0039] In addition to being able to form a filter screen, the vertical bars 10 and horizontal bars 11 can also increase the contact area between the counterweight and the filler. This allows the filler to be fixed to the vertical bars 10 and horizontal bars 11 after it clumps together. This effectively prevents the relative displacement between the internal filler and the shell 1 when the elevator counterweight is subjected to external force, preventing the filler from breaking and thus effectively improving the structural strength.

[0040] By opening through grooves 7 and grooves 8 on the surface of housing 1, the deformation resistance of housing 1 can be effectively improved. The handle 9 can be easily operated during handling. By setting limiting protrusions 5 and limiting grooves 6, the vertically stacked elevator counterweights can be mutually limited to prevent the elevator counterweights from shaking during transportation. At the same time, there are two limiting grooves 6 at the bottom of housing 1, which can facilitate the insertion of forklift forks and facilitate batch transportation.
