Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to elevator counterweight protection components. Background Technology

[0002] The counterweight is a core component of a traction elevator, primarily used to balance the weight of the car, reduce energy consumption, and ensure operational safety. The basic structure of the counterweight consists of a counterweight frame, counterweight blocks (or concrete blocks), and guide shoes. The counterweight is symmetrically suspended from the car via traction steel cables, and its weight is typically 40%-50% of the car's own weight plus the rated load (e.g., 40-50kg counterweight for a 100kg car), thereby reducing the burden on the motor and improving traction efficiency. To prevent fingers or other body parts from accidentally entering the counterweight area, protective netting or railings are required on the outside of the counterweight.

[0003] For example, the utility model with patent publication number CN219489320U discloses an elevator counterweight protection device and an elevator counterweight. The elevator counterweight protection device includes multiple guardrail brackets, a protective plate, and a slot. The multiple guardrail brackets are installed on the counterweight guide rail and are spaced apart along the length of the counterweight guide rail. The protective plate is disposed between two adjacent guardrail brackets, and the slot can simultaneously engage the protective plate and the guardrail bracket to limit the protective plate to the corresponding guardrail bracket.

[0004] The above-mentioned patent has the following problems when in use: although a protective surface is provided by setting a protective railing bracket on the outside of the elevator counterweight, when it is necessary to inspect the elevator counterweight area, the disassembly and assembly of the protective railing bracket greatly affects the inspection and construction, and the operation is relatively inconvenient.

[0005] Therefore, it is necessary to invent elevator counterweight protection components to solve the above problems. Utility Model Content

[0006] Therefore, this utility model provides an elevator counterweight protection component to solve the problem in the prior art that the inconvenience of disassembling and assembling counterweight protection facilities affects the progress of elevator counterweight maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An elevator counterweight protection component includes a pair of counterweight guide rails, each of which is equipped with a fixing component. It also includes a pair of protective guide shoes, which are mounted on the fixing components. Multiple baffles are provided between the pair of protective guide shoes, and folding hinges are provided between adjacent baffles. A flexible connecting component is also provided between adjacent baffles. Each protective guide shoe is equipped with a limit component, which is connected to the elastic connecting component.

[0008] Furthermore, the fixing component includes a wall fixing plate, on which a guide rail fixing plate is bolted, and the guide rail fixing plate is bolted to the counterweight guide rail.

[0009] Furthermore, the protective guide shoe and the guide rail fixing plate are connected by bolts to the guide shoe fixing plate.

[0010] Furthermore, the bottom of the protective guide shoe is provided with a sealing plate.

[0011] Furthermore, the flexible connection assembly includes a guide slide seat rotatably connected to the end side of each baffle, the guide slide seat being slidably connected inside the protective guide shoe, and a connecting rope being fixedly connected between adjacent guide slide seats.

[0012] Furthermore, the protective guide shoe has a moving groove and a locking groove on its front side, the moving groove and the locking groove are connected to each other, the limiting component includes a rotating support rod fixedly connected to the guide slide seat located at the top, a pull plate rotatably connected to the rotating support rod, a limiting post fixedly connected to one end of the pull plate, the rotating support rod slidably connected in the moving groove, and the limiting post locking in the locking groove.

[0013] Furthermore, a connecting rod is fixedly connected between the pair of rotating struts.

[0014] Furthermore, each baffle has a reflective strip on its front side.

[0015] This utility model has the following advantages: This elevator counterweight protection component features multiple baffles installed on the front side of the counterweight guide rail used to guide the elevator counterweight's sliding. A flexible connecting component provides flexible support for adjacent baffles, and a limiting component applies limiting tension to the top flexible connecting component. Adjacent baffles can be unfolded and folded via folding hinges. The unfolded baffles form a protective surface to prevent fingers or other body parts from accidentally entering the counterweight area. The folded baffles easily expose the counterweight area, providing effective maintenance space for the counterweight. This enhances the flexibility of elevator counterweight protection and maintenance. Because the protection component in this application can quickly form a counterweight protection surface simply by pushing and pulling, elevator counterweight maintenance can be performed quickly without disassembling the protective facilities, making it convenient to use.

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] See also Figures 1-6 This utility model provides an elevator counterweight protection component, including a pair of counterweight guide rails 1, each counterweight guide rail 1 is provided with a fixing component 2, the fixing component 2 includes a wall fixing plate 21, a guide rail fixing plate 22 is bolted to the wall fixing plate 21, and the guide rail fixing plate 22 is bolted to the counterweight guide rail 1.

[0022] The wall mounting plate 21 can be fixed to the wall of the elevator shaft with expansion bolts. The counterweight guide rail 1 can be fastened to the wall mounting plate 21 with the guide rail mounting plate 22. By stabilizing the position of the counterweight guide rail 1, the counterweight guide rail 1 can guide the elevator counterweight to slide.

[0023] This utility model provides an elevator counterweight protection component, which also includes a pair of protective guide shoes 3. The protective guide shoes 3 are mounted on the fixed component 2, and the protective guide shoes 3 and the guide rail fixed plate 22 are connected by bolts to the guide shoe fixed plate 9.

[0024] The protective guide shoes 3 are located in front of the counterweight guide rail 1. Since there is a pair of protective guide shoes 3, the pair of protective guide shoes 3 can guide the structure used to protect the elevator counterweight to slide.

[0025] In this embodiment, a sealing plate 10 is provided at the bottom of the protective guide shoe 3.

[0026] The sealing plate 10 can be connected to the bottom of the protective guide shoe 3 by screws, so that the bottom of the rail groove of the protective guide shoe 3 can be sealed to prevent the internal structure of the rail from moving out.

[0027] In this embodiment: multiple baffles 4 are provided between a pair of protective guide shoes 3, and folding hinges 5 are provided between adjacent baffles 4.

[0028] The baffle 4 is made of acrylic material, which is lightweight and has high structural strength. The longitudinal and horizontal arrangement of multiple baffles 4 can form a protective surface in the elevator centering area. This protective surface prevents fingers or other body parts from accidentally entering the counterweight area. Due to the use of folding hinges 5, the angle of inward folding of adjacent baffles 4 can be close to 0 degrees. In this way, when it is necessary to expose the elevator counterweight area for counterweight maintenance, the height and area of ​​the protective surface can be easily and quickly reduced by folding.

[0029] In this embodiment, each baffle 4 has a reflective strip 11 on its front side.

[0030] The reflective strip 11 can reflect light, especially when maintaining the elevator at night. The reflective strip 11 uses reflection to indicate the position of the baffle 4, thus achieving the effect of warning the heavy area.

[0031] In this embodiment: a flexible connection assembly is provided between adjacent baffles 4. The flexible connection assembly includes a guide slide seat 6 rotatably connected to the end side of each baffle 4. The guide slide seat 6 is slidably connected inside the protective guide shoe 3. A connecting rope 7 is fixedly connected between adjacent guide slide seats 6.

[0032] Both ends of the baffle 4 are provided with flexible connecting components. The guide slides 6 at the same end and adjacent to each other are respectively set at the highest end and the lowest end of the adjacent baffle 4. That is, one guide slide 6 is set at the top of the end of the upper baffle 4 and the other guide slide 6 is set at the top of the end of the lower baffle 4. In this application, the guide slide 6 is set with an inverted "concave" structure. When the adjacent baffle 4 is folded and the adjacent guide slide 6 is brought closer, the hollow interior of the guide slide 6 can increase the storage space for the connecting rope 7. The connecting rope 7 is made of nylon braided rope.

[0033] In use, by applying an upward pulling force to the guide slide 6 located at the top, the guide slide 6 slides upward within the protective guide shoe 3, which can provide a pulling force to the baffle 4. Since the connecting rope 7 is connected to the adjacent guide slide 6, multiple baffles 4 can be pulled up under the hinge of the folding hinge 5 and form a protective surface. Since the protective surface is located in front of the elevator counterweight, it can prevent fingers or other body parts from accidentally entering the counterweight area and causing injury.

[0034] In this embodiment: each protective guide shoe 3 is provided with a limiting component 8, and the limiting component 8 is connected to the elastic connecting component. The front of the protective guide shoe 3 is provided with a moving groove 12 and a locking groove 13, which are connected to each other. The limiting component 8 includes a rotating support rod 81 fixedly connected to the guide slide seat 6 located at the top. A pull plate 82 is rotatably connected to the rotating support rod 81. One end of the pull plate 82 is fixedly connected to a limiting post 83. The rotating support rod 81 is slidably connected in the moving groove 12, and the limiting post 83 is locked in the locking groove 13.

[0035] The upward pulling force provided by the guide slide seat 6 located at the top position can be provided by the limiting component 8. The specific operation method is as follows: the operator can directly use the hand or the rod structure to pull the limiting post 83 upward. Then the limiting post 83 can drive the guide slide seat 6 located at the top to move upward in the protective guide shoe 3 through the pull plate 82 and the rotating support rod 81 in sequence. When the limiting post 83 is close to the slot 13, since the limiting post 83 is rotatably connected to the rotating support rod 81 through the pull plate 82, the limiting post 83 enters the slot 13 by rotating it. In this way, the limiting post 83 can be hooked in the slot 13, and the protective surface of the multiple baffles 4 can be fixed.

[0036] Similarly, when the counterweight area of ​​the elevator needs to be inspected, the limiting column 83 in the slot 13 can be disengaged. Under the action of gravity, the multiple baffles 4 can drive the guide slide 6 to slide down in the protective guide shoe 3. At the same time, the baffles 4 rotate on the guide slide 6 and are folded and stored through the folding hinge 5. In this way, the protective surface formed by the multiple baffles 4 can be stored by folding, reducing the space occupation rate, which makes it easy to expose the counterweight area.

[0037] Since the baffle 4 can quickly form a counterweight protection surface by simply pushing and pulling, the elevator counterweight can be quickly maintained without disassembling the protective facilities, making it relatively convenient to use.

[0038] In this embodiment, a connecting rod 14 is fixedly connected between a pair of rotating support rods 81.

[0039] Since there is only one pair of limiting components 8, in order to prevent the baffle 4 from getting stuck when moving upward, the connecting rod 14 is designed so that the guide slides 6 at the top corresponding to the pair of rotating support rods 81 can be horizontally connected. In this way, the pair of guide slides 6 at the top can move synchronously, ensuring the smoothness of the movement of the baffle 4.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
