Description

Technical Field

[0001] This utility model relates to an improvement of an elevator guide rail production device, specifically an elevator guide rail damping agent injection device. Background Technology

[0002] Elevator guide rails are fundamental devices that provide linear guidance for the vertical movement of the elevator car and counterweight. Commonly used elevator guide rail types include T-shaped guide rails and hollow guide rails, which are selected according to different loads. Hollow guide rails are often used to guide the counterweight frame. Hollow guide rails are relatively lightweight and easy to install. However, the cavity inside the hollow guide rail is relatively large. During the vertical movement of the counterweight frame, the vibration will increase the transmission of noise and affect the comfort of the elevator ride. Therefore, foamed damping material is added to the cavity during the production of the guide rail to reduce the transmission of noise. Therefore, this design proposes a device for adding damping agent to the guide rail. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the existing technology and to provide an elevator guide rail damping agent injection device.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the damping agent filling device includes a linear platform, a sprocket drive device is set in the linear platform, and multiple conveying wheels are set on one side of the linear platform. All conveying wheels are connected to the sprocket drive device and driven to rotate. Support grooves are formed on the outer edge of the conveying wheels. The inner width of the support grooves corresponds to the outer convex part of the guide rail. The back cavity of the guide rail is set upward. The support grooves of all conveying wheels are collinear. The guide rail as a whole is driven by the conveying wheels and moves linearly. There is also a filling component on the linear platform. The filling component is set downward and corresponds to the cavity on the back of the guide rail. A nozzle is set at the bottom of the filling component. The nozzle enters the cavity and fills the foamed damping agent. The linear platform provides the basic structure for the linear movement of the guide rail. A linearly arranged conveyor wheel is mounted on it, driven by a sprocket structure. The guide rail and the conveyor wheel are connected by a support groove, which supports the guide rail. The guide rail's back cavity faces upwards for easy filling. The filling component is positioned downwards, directly entering the gap for filling, thus achieving automatic filling of the damping agent and high production efficiency.

[0005] Furthermore, the dispensing component includes a geared motor, a mixer, a feeder, a feed pipe, and a nozzle. The output end of the geared motor is connected to the mixer, and a spiral auger is installed on the output end. The spiral auger rotates in the mixer. Feeders are installed on the side of the mixer; there are two or more feeders, each connected to a feed pipe. A nozzle is installed at the lower end of the mixer. The spiral auger rotates and stirs the mixture in the mixer, pushing the damping agent to the nozzle. The dispensing component uses a geared motor to propel the damping agent. The mixer is used for stirring the damping agent. Foaming damping agents are typically a mixture of agent A and agent B to form a foamed material. Therefore, the feeder delivers different additives through the feed pipe. After stirring and mixing in the mixer, the mixture is pushed out to the nozzle by the spiral auger. The damping agent solidifies in the cavity of the guide rail, forming a damping structure.

[0006] Furthermore, the filling component is fixed to the linear platform via an adjustable bracket. The adjustable bracket includes a fixed frame and a height adjustment frame. The fixed frame is upright and fixed to the linear platform, and the height adjustment frame is connected to the fixed frame. Both the height adjustment frame and the fixed frame have corresponding height adjustment holes. The fixed frame and the height adjustment frame change their support height by fixing different heights at the height adjustment holes. The adjustable bracket provides height adjustment functionality to control the depth of the nozzle entering the guide rail cavity. Adjustment is mainly achieved through the height adjustment holes, and the position is locked by tightening fixing pins in the height adjustment holes.

[0007] Furthermore, the linear stage is equipped with a contact switch, positioned before the guide rail enters below the dispensing component. The contact switch includes a swing rod, a contact wheel, and a micro switch. The swing rod is rotatably connected to the contact switch. In a vertical state, the swing rod does not contact the micro switch; in an angled state, it contacts the micro switch. The contact wheel is rotatably connected to the swing rod and makes rolling contact with the surface of the guide rail. The contact switch's function is to initiate the dispensing action of the dispensing component. It primarily works in conjunction with the reduction motor. During the linear movement of the guide rail, after contacting the swing rod, the swing rod contacts the micro switch, triggering the circuit and activating the dispensing component, thus achieving automated operation. The contact wheel ensures rolling contact, preventing scratches on the guide rail surface.

[0008] Furthermore, the contact switch is mounted on a linear platform via a position adjustment frame. The position adjustment frame includes two upright plates arranged opposite each other, with a horizontal bar connecting them. The contact switch is fixed to the horizontal bar by fasteners and locked at any position on the horizontal bar. The position of the contact switch is adjustable. Based on the linear velocity of the guide rail and the position of the refueling component, a suitable position can be set, allowing the refueling component to begin refueling at the corresponding time, achieving more precise operation.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is a device for adding damping agent to elevator guide rails, which can realize the function of automatically adding damping agent to the guide rails to meet the damping requirements of the guide rails. It is suitable for mass production, has high work efficiency, safe and stable production process, and improves economic benefits. Attached Figure Description
