Description

Technical Field

[0001] This utility model belongs to the field of elevator parts processing technology, and specifically relates to a tooling for smoothing elevator counterweight blocks. Background Technology

[0002] The main function of elevator counterweights is to balance the weight of the car, reduce the motor load, improve operating efficiency and safety, and at the same time reduce energy consumption and noise.

[0003] The existing concrete elevator counterweight processing process generally involves first welding a layer of steel bars into a cast iron mold, then placing the cast iron mold on a vibrating platform, and pouring concrete mortar while vibrating. After the cast iron mold is filled with concrete mortar, it is manually dragged to a non-powered roller line, and the excess concrete mortar at the top of the cast iron mold is smoothed out using a trowel.

[0004] However, during the smoothing process, excess concrete mortar will fall along the side wall of the cast iron mold onto the roller conveyor. This will not only cause serious pollution to the surface of the roller conveyor, but also affect the transmission of the roller conveyor after the excessive concrete mortar solidifies. In addition, a large area of ​​the side wall of the cast iron mold needs to be wiped and cleaned, which will affect the processing efficiency of the heavy blocks. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a tooling for leveling elevator counterweights. The specific technical solution is as follows:

[0006] This utility model provides an elevator counterweight leveling fixture, which is mounted on the front end of a non-powered roller conveyor. The fixture includes four vertically symmetrically distributed columns on both sides of the front end of the roller conveyor. A horizontally placed receiving groove is slidably inserted through the four columns. A mold box sleeve hole is opened through the middle of the receiving groove along the extension direction of the roller conveyor, and unloading ports are symmetrically opened on both sides. Limiting blocks are horizontally symmetrically fixed and sleeved on the four columns at the same horizontal height. When the receiving groove falls onto the limiting block, the mold box sleeve hole of the receiving groove is fitted with the top edge of a cast iron mold box containing concrete that is transported to the roller conveyor and located directly below it.

[0007] As a preferred technical solution of this utility model, the tooling also includes guide components symmetrically distributed along the center line of the front end of the roller line;

[0008] The guide assembly includes a guide plate that is horizontally spaced above the roller line. The two ends of the guide plate are fixedly suspended to the corresponding columns by vertically symmetrically connected suspension rods, and the suspension rods are located below the corresponding limit blocks. The outer side of the guide plate is symmetrically provided with scale grooves along its vertical center line. The distance between the two scale grooves is the same as the length of the corresponding long side of the middle part of the mold box hole, and the two are aligned vertically.

[0009] As a preferred technical solution of this utility model, a reinforcing plate is horizontally and vertically connected between the tops of two columns on the same side, and the reinforcing plate is detachably suspended from the corresponding end face of the receiving trough by a suspension assembly.

[0010] As a preferred embodiment of the present invention, the suspension assembly includes a hanging ring hinged to the end face of the receiving groove, which can be suspended by a hook disposed on a corresponding reinforcing plate.

[0011] As a preferred embodiment of this utility model, the discharge port of the receiving trough is longitudinally connected to a feeding trough, and a receiving container can be placed directly below the feeding trough.

[0012] As a preferred embodiment of this utility model, the front ends of the two guide plates are respectively symmetrically connected with receiving plates that are inclined outwards.

[0013] As a preferred technical solution of this utility model, the tooling also includes a pulling and wiping component that is longitudinally slidably sleeved on the column and fixedly connected with the receiving groove at vertical intervals.

[0014] The trowel assembly includes four collar blocks that are slidably fitted longitudinally to corresponding columns. Two collar blocks on the same end side are connected by a matching straight plate. Two guide rods are horizontally and vertically spaced between the middle of the two straight plates. Mounting plates are slidably fitted laterally on the two guide rods. A horizontally arranged smoothing block is detachably connected to the bottom end of the mounting plate. The bottom surface of the smoothing block is flush with the top surface of the cast iron mold box on the roller line, and the length of the smoothing block is greater than or equal to the width of the middle part of the cast iron mold box. The straight plate and the corresponding end face of the receiving groove are fixedly connected by at least one support plate.

[0015] As a preferred technical solution of this utility model, the inner side of the smoothing block is integrally provided with a wedge-shaped part, and the wedge-shaped part and the smoothing block are provided with a rounded corner transition.

[0016] As a preferred embodiment of this utility model, a handle is provided on the inner surface of the top of the mounting plate.

[0017] As a preferred embodiment of this utility model, a baffle is vertically provided at the rear end of the roller conveyor.

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, the mold box sleeve hole in the middle of the receiving groove forms a gap fit with the top edge of the cast iron mold box. During the smoothing process, it can effectively receive the concrete mortar overflowing from the top opening of the cast iron mold box. The discharge port on the receiving groove allows operators to collect the residual mortar from both sides, preventing it from falling directly onto the roller line and avoiding large-area contamination of the side walls of the cast iron mold box. This structure solves the problem of mortar contamination of the roller line in the traditional smoothing process, avoids the situation where solidified mortar affects the transmission function; and eliminates the need for large-area wiping and cleaning of the side walls of the cast iron mold box, improving the processing efficiency of heavy blocks.

[0020] 2. This utility model uses a limiting block on the column to fix the falling position of the receiving groove, ensuring that the mold box sleeve hole and the cast iron mold box remain aligned. This liftable structure facilitates the transfer of the cast iron mold box when the receiving groove is raised, and can be quickly positioned to the working height by the limiting block when falling, thus achieving seamless connection between tooling and production process.

[0021] 3. This utility model is directly installed at the front end of the roller conveyor, forming a continuous working space for "pouring-transferring-smoothing". After the cast iron mold box is in place, the material receiving trough is manually lowered to complete the positioning. The smoothing operation and mortar collection are carried out simultaneously, indirectly improving processing efficiency. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. Example

[0030] To address the technical problems in the background section, the following elevator counterweight leveling fixture is provided:

[0031] Combination Figures 1-3 As shown, an elevator counterweight leveling fixture is mounted on the front end of a non-powered roller conveyor 9. The fixture includes four vertically symmetrically distributed columns 1 on both sides of the front end of the roller conveyor 9. A horizontally placed receiving groove 3 is slidably inserted through the four columns 1. A mold box sleeve hole 31 is opened through the middle of the receiving groove 3 along the extension direction of the roller conveyor 9, and unloading ports 32 are symmetrically opened on both sides. Limiting blocks 11 are fixedly and symmetrically fixed at the same horizontal height on the four columns 1. When the receiving groove 3 falls onto the limiting block 11, the mold box sleeve hole 31 of the receiving groove 3 is fitted with the top edge of the cast iron mold box 10 containing concrete that is transferred to the roller conveyor 9 and located directly below it.

[0032] By adopting the above technical solution, the mold box sleeve hole 31 in the middle of the receiving groove 3 of the smoothing fixture forms a gap fitting with the top edge of the cast iron mold box 10. During the smoothing process, it can effectively receive the concrete mortar overflowing from the top opening of the cast iron mold box 10. The discharge port 32 opened on the receiving groove 3 allows the operator to clean up the collected residual mortar from both sides, preventing it from falling directly onto the roller line 9 and avoiding large-area contamination of the side wall of the cast iron mold box 10. This structure solves the problem of mortar contamination of the roller line 9 in the traditional smoothing process, avoids the situation where solidified mortar affects the transmission function; and eliminates the need for large-area wiping and cleaning of the side wall of the cast iron mold box 10, improving the processing efficiency of heavy blocks.

[0033] The smoothing fixture uses a limiting block 11 on the column to fix the falling position of the receiving groove 3, ensuring that the mold box sleeve hole 31 is aligned with the cast iron mold box 10. This liftable structure facilitates the transfer of the cast iron mold box 10 when the receiving groove 3 is raised, and can be quickly positioned to the working height when falling by the limiting block 11, achieving seamless connection between the fixture and the production process.

[0034] The smoothing fixture is directly installed at the front end of the roller conveyor 9, forming a continuous working space for "pouring-transferring-smoothing". After the cast iron mold box 10 is in place, the material receiving trough 3 is manually lowered to complete the positioning. The smoothing operation and mortar collection are carried out simultaneously, which indirectly improves the processing efficiency.

[0035] like Figures 1-3 As shown, the tooling also includes guide components 4 symmetrically distributed along the center line of the front end of the roller line 9;

[0036] The guide assembly 4 includes a guide plate 42 that is horizontally spaced above the roller line 9. The two ends of the guide plate 42 are fixedly suspended to the corresponding column 1 by vertically symmetrically connected suspension rods 41, and the suspension rods 41 are located below the corresponding limiting block 11. The outer side of the guide plate 42 is symmetrically provided with scale grooves 421 along its vertical center line. The distance between the two scale grooves 421 is the same as the length of the corresponding long side of the middle part of the mold box hole 31, and the two are aligned vertically.

[0037] By adopting the above technical solution, the guide plate 42 is fitted with the cast iron mold box 10 above the roller conveyor 9 with a clearance, automatically correcting its running trajectory when the cast iron mold box 10 is manually dragged, ensuring that the cast iron mold box 10 always moves along the center line of the roller conveyor 9. This design solves the problem of easy deviation in traditional manual pushing.

[0038] The distance between the two scale grooves 421 is the same as the length of the corresponding long side of the middle part of the mold box hole 31, and the two are aligned vertically. In this way, the operator can quickly determine whether the cast iron mold box is centered by observing the visual overlap between the side wall of the cast iron mold box 10 and the scale groove 421 without the need for additional measuring tools. This ensures that the cast iron mold box 10 can be aligned vertically with the mold box hole 31 of the receiving groove 3 more quickly when it reaches the smoothing station, reducing the waiting time for repeatedly adjusting the position of the cast iron mold box 10 and indirectly improving the processing efficiency of heavy blocks.

[0039] like Figure 1 and Figure 2 As shown, preferably, the front ends of the two guide plates 42 are respectively symmetrically connected to receiving plates 422 that are inclined outward.

[0040] By adopting the above technical solution, the two guide plates 422 form an "eight"-shaped entrance structure, which can better guide the cast iron mold box 10 into the smoothing channel formed by the two guide plates 42.

[0041] like Figures 1-3 As shown, preferably, the discharge port 32 of the receiving trough 3 is longitudinally connected to the feeding trough 5, and a receiving container (not shown in the figure) can be placed directly below the feeding trough 5.

[0042] By adopting the above technical solution, the discharge port 32 of the feeding trough 5 and the receiving trough 3 are longitudinally connected to form a continuous mortar flow path. The concrete mortar overflowing during the smoothing process is scraped off manually with a trowel and slides into the feeding trough through the discharge port 32, and finally falls into the receiving container below, avoiding the pollution problem of the roller line 9 caused by the free fall of mortar in the traditional process.

[0043] like Figures 1-3 As shown, a reinforcing plate 2 is horizontally and vertically connected between the tops of two columns 1 on the same side. The reinforcing plate 2 is detachably suspended from the corresponding end face of the receiving trough 3 by a suspension assembly 6.

[0044] The suspension assembly 6 includes a hanging ring 61 hinged to the end face of the receiving groove 3, which can be suspended by a hook 62 provided on the corresponding reinforcing plate 2.

[0045] By adopting the above technical solution, the reinforcing plate 2 is horizontally and vertically connected to the tops of the two columns 1 on the same side, forming a closed rectangular load-bearing frame, transforming the originally independent four columns 1 into an integral support structure. This design improves the torsional stiffness of the tooling and effectively resists the eccentric load moment during the lifting and lowering of the receiving trough 3.

[0046] The suspension component 6 can be in a raised and suspended state when the receiving trough 3 is not in use; the suspension component 6 adopts a flip-type hook connection between the hanging ring 61 and the hook 62, which makes it easy for the receiving trough 3 to quickly switch between the raised and suspended state and the lowered and smoothing working state.

[0047] like Figure 2 and Figure 3 As shown, a baffle 91 is vertically installed at the rear end of the roller line 9. The baffle 91 can prevent the counterweight block after smoothing from rolling off the smoothing station to the rear end of the roller line 9 from accidentally rolling off. Example

[0048] Combination Figures 4-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0049] In this embodiment, as Figure 4 and Figure 5 As shown, the tooling also includes a pulling and wiping assembly 7 that is longitudinally slidably sleeved on the column 1 and fixedly connected to the material receiving groove 3 at vertical intervals;

[0050] The trowel assembly 7 includes four collar blocks 71 that are longitudinally slidably sleeved with the corresponding columns 1. Two collar blocks 71 on the same end side are connected by a matching straight plate 72. Two guide rods 73 are horizontally and vertically spaced between the middle of the two straight plates 72. Mounting plates 74 are laterally slidably sleeved on the two guide rods 73. A horizontally arranged smoothing block 75 is detachably connected to the bottom end of the mounting plate 74. The bottom surface of the smoothing block 75 is flush with the top surface of the cast iron mold box 10 on the roller line 9, and the length of the smoothing block 75 is greater than or equal to the width of the middle part of the cast iron mold box 10. The straight plate 72 is fixedly connected to the corresponding end face of the receiving groove 3 by at least one support plate 8.

[0051] By adopting the above technical solution, the set trowel component 7 can replace the traditional trowel and use an assembly line to smooth the concrete mortar at the top opening of the cast iron mold box 10 more quickly.

[0052] The bottom surface of the smoothing block 75 in the set-up smoothing assembly 7 is flush with the top surface of the cast iron mold 10, ensuring that the smoothing surface is always flush with the top surface of the cast iron mold 10. Manually pulling the mounting plate 74 along the guide rod 73 allows the smoothing block 75 at the bottom of the mounting plate 74 to smooth the concrete mortar at the top opening of the cast iron mold 10, avoiding uneven smoothing caused by the arc-shaped trajectory of manual operation. The length of the smoothing block 75 is greater than or equal to the width of the middle part of the cast iron mold 10, and a single action can completely cover the smoothing area.

[0053] Preferably, the bottom of the trowel block 75 is treated with a mirror finish to reduce the surface roughness of the concrete mortar after troweling, and to reduce tool scratches and joint marks caused by traditional troweling.

[0054] Workers only need to pull the mounting plate 74 horizontally to complete the smoothing (replacing the original repeated scraping motion of the wrist), which effectively reduces the operating force compared to the traditional smoothing method and eliminates the risk of muscle strain.

[0055] The support plate 8 can both allow the trowel assembly 7 and the receiving groove 3 to slide up and down synchronously along the column 1, and keep the bottom surface of the trowel block 75 flush with the top surface of the cast iron mold box 10 on the roller line 9.

[0056] like Figure 5 As shown, preferably, the inner side of the smoothing block 75 is integrally provided with a wedge-shaped portion 751, and the wedge-shaped portion 751 and the smoothing block 75 are provided with a rounded corner transition.

[0057] By adopting the above technical solution, the wedge-shaped part 751 can form an inclined surface on the inner side of the slurry block 75. When the mounting plate 74 moves laterally, a gradually narrowing gap is formed between the inclined surface and the concrete, forcing the overflowing mortar to be pressed back into the cast iron mold box 10 along the inclined surface. The wedge-shaped part 751 changes the direction of the surface tension of the concrete fluid, transforming the horizontal splashing tendency into a centripetal cohesive flow, thus eliminating the amount of splashing pollution during the slurrying process.

[0058] A rounded corner transition is provided between the wedge-shaped part 751 and the smoothing block 75, which can eliminate the dead corners where mortar stagnates at traditional right-angled edges and achieve smooth guidance of mortar fluid.

[0059] like Figure 5 and Figure 6 As shown, preferably, a handle 76 is provided on the inner top surface of the mounting plate 74. The handle 76 is convenient for manual gripping.

[0060] like Figure 4 and Figure 6 As shown, preferably, the reinforcing plate 2 and the straight plate 72 are detachably suspended by a suspension assembly 6; the suspension assembly 6 includes a hanging ring 61 hinged to the straight plate 72, which can be suspended by a hook 62 provided on the corresponding reinforcing plate 2.

[0061] By adopting the above technical solution, the suspension component 6 can be in a raised and suspended state when the material receiving trough 3 and the troweling component 7 are not in use; the suspension component 6 adopts a flip-type hook connection between the hanging ring 61 and the hook 62, which facilitates the quick switching between the raised and suspended state and the lowered and smoothing working state of the material receiving trough 3 and the troweling component 7.

[0062] Working principle and usage process of this utility model:

[0063] When the tooling is idle, the receiving trough 3 and the pulling assembly 7 are in a raised state via the suspension assembly 6 (i.e., the hanging ring 61 is hooked onto the hook 62 of the reinforcing plate 2). Before use, the hooks are manually flipped to release them, and both automatically fall to the limiting block 11 under gravity.

[0064] The cast iron mold 10, filled with concrete mortar, is manually pushed along the roller line 9. The V-shaped structure of the front receiving plate 422 initially corrects the position of the cast iron mold 10; the cast iron mold 10 continues to slide into the channel between the two guide plates 42, and the operator visually calibrates the center position through the scale groove 421. After the cast iron mold 10 is in place, its top edge is embedded in the mold sleeve hole 31. Before smoothing begins, the receiving groove 3 has already wrapped around the top outer edge of the cast iron mold 10.

[0065] The worker pulls the handle 76 horizontally, causing the mounting plate 74 to move linearly along the guide rod 73. The smoothing block 75 completes the full-width smoothing with a single push and pull. During the smoothing process: the wedge-shaped part 751 squeezes the overflowing mortar back into the cast iron mold box 10; the remaining mortar falls into the receiving trough 3, and enters the feeding trough 5 through the discharge port 32 and is guided into the bottom receiving container.

[0066] After completion, the receiving trough 3 and the troweling assembly 7 are manually lifted and fixed by the hook of the suspension assembly 6. The baffle 91 at the rear end of the roller conveyor 9 prevents the smoothed cast iron mold 10 from sliding out of its travel range. The smoothed cast iron mold 10 is removed from the roller conveyor 9 for subsequent curing and solidification molding processes to form the final concrete elevator counterweight.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
