Technical Field

[0001] The utility model relates to the technical field of guide rail speed limiting, in particular to a guide rail speed limiting device. Background Art

[0002] The elevator guide rail is an important part of the elevator system. It guides and supports the elevator car. The main function of the speed limiter is to monitor and control the running speed of the elevator at any time, and send a signal in time when an overspeed occurs, which then generates a mechanical action to cut off the power supply circuit and brake the traction mechanism.

[0003] Traditionally, the installation process for a speed governor typically involves first securing the governor to a specific plate, then using tools to bolt the plate to the guide rail. However, since elevator guide rails come in a variety of sizes and specifications, this method requires selecting a suitable plate based on the specific guide rail dimensions. This not only complicates the selection process but also reduces guide rail installation flexibility and applicability. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that elevator guide rails have various sizes and specifications, and the method requires selecting an adaptive plate according to the specific size of the guide rail, which not only increases the complexity of selection, but also leads to poor installation flexibility and low applicability of the guide rail. A guide rail speed limiting device is proposed to solve the problem that the elevator guide rails have various sizes and specifications, and the method requires selecting an adaptive plate according to the specific size of the guide rail, which not only increases the complexity of selection, but also leads to poor installation flexibility and low applicability of the guide rail.

[0009] The movable seat is provided with a movable member for moving the fixed plate.

[0010] Preferably, the moving member includes a screw threadedly connected to the moving seat, and the screw and the fixed plate are rotatably connected via a bearing.

[0012] Preferably, one end of the bidirectional lead screw extends to the outside of the mounting chamber and is fixed with a rocker, and the end of the screw away from the fixing plate is fixed with a rotating wheel.

[0013] Preferably, the front of the installation bin is movably connected to an opening and closing door via a hinge, and a handle is fixed on the opening and closing door.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model adopts the setting of the transmission structure, and when the speed limiter needs to be installed on different guide rail bodies, the two fixing plates are tightly attached to the guide rail body by rotating the bidirectional lead screw and the screw, thereby realizing the overall installation of the speed limiter connected to the installation chamber.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 3 A guide rail speed limiting device includes a guide rail body 1 and a speed limiter 2 arranged relative to the guide rail body 1. The speed limiter 2 is a prior art and can detect the running speed of the elevator.

[0022] The guide rail body 1 is provided with a mounting compartment 3, located in a dedicated area on the guide rail body 1, for accommodating and securing key components. A pair of L-shaped abutment plates 4 are fixed to the mounting compartment 3, contacting the guide rail body 1. The arrangement of the L-shaped abutment plates 4 provides sufficient space for the movement of components within the mounting compartment 3, facilitating subsequent operations.

[0023] A pair of fixing plates 5 are provided on the installation chamber 3 ; the fixing plates 5 are used to be fixed to the guide rail body 1 , thereby achieving fixed installation of the entire installation chamber 3 .

[0024] The mounting compartment 3 is provided with a transmission structure for fixing the two fixing plates 5 relative to the guide rail body 1 .

[0025] The transmission structure includes a bidirectional lead screw 6 rotatably connected to the inner wall of the mounting chamber 3. A pair of movable seats 8 are threadedly connected to the lead screw 6. Rotation of the lead screw 6 enables the two movable seats 8 to move toward or away from each other. Limiting slots 9 are defined in the inner wall of the mounting chamber 3, with the movable seats 8 slidingly connected to the limiting slots 9 horizontally. The provision of the limiting slots 9 ensures stable movement of the movable seats 8 along the axis of the lead screw 6, preventing the lead screw 6 from causing the movable seats 8 to rotate and cause position deviation.

[0026] The movable seat 8 is provided with a movable member for moving the fixed plate 5 .

[0027] The moving member includes a screw 10 threadedly connected to the moving base 8. The screw 10 and the fixed plate 5 are rotatably connected via a bearing. The screw 10 is rotated to adjust the horizontal position of the fixed plate 5 so that the fixed plate 5 and the guide rail body 1 are in contact, thereby achieving fixation. The rotating arrangement of the fixed plate 5 and the screw 10 prevents the screw 10 from affecting the positioning of the fixed plate 5 during rotation.

[0028] The mounting chamber 3 is provided with a sliding opening 12 for facilitating the movement of the screw rods 10. The two screw rods 10 can move relative to or away from each other in the sliding opening 12 at the same time, and the position of the screw rods 10 can also be adjusted by rotating the screw rods 10 in the sliding opening 12.

[0029] One end of the bidirectional lead screw 6 extends to the outside of the installation chamber 3 and is fixed with a rocking wheel 7. The setting of the rocking wheel 7 makes it convenient for the staff to rotate the bidirectional lead screw 6 without opening the opening and closing door 13.

[0030] A rotating wheel 11 is fixed to one end of the screw rod 10 away from the fixing plate 5. The setting of the rotating wheel 11 is ergonomic and convenient for the staff to rotate the screw rod 10.

[0031] The front of the installation chamber 3 is movably connected to an opening and closing door 13 by a hinge, and a handle is fixed on the opening and closing door 13. The setting of the opening and closing door 13 plays a certain sealing role on the installation chamber 3, preventing dust from entering the installation chamber 3 and affecting the mechanical transmission operation inside the installation chamber 3.

[0032] The functional principle of this utility model can be explained through the following operation modes:

[0033] Before using the guide rail speed limiting device, the first step is to ensure that the elevator has completely stopped running and is in a safe and stable state to prevent any accidents during operation.

[0034] Next, the operator needs to open the door 13 on the installation chamber 3 to access the internal mechanical components. At this point, by rotating the crank wheel 7 at the end of the bidirectional lead screw 6, the position of the movable base 8 can be precisely adjusted. Specifically, rotating the crank wheel 7 clockwise or counterclockwise will drive the two movable bases 8 toward or away from each other, allowing operators to flexibly adjust the positions according to actual needs.

[0035] After the movable base 8 is adjusted to the appropriate position, the next step is to rotate the wheel 11 on the screw 10 to finely adjust the horizontal position of the fixing plate 5 to ensure that it can fit closely with the guide rail body 1, thereby achieving a firm fixation.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
