Description

Technical Field

[0001] This application relates to the field of elevator accessories technology, specifically to an installation structure for a side-mounted explosion-proof elevator speed governor. Background Technology

[0002] The elevator speed governor is one of the safety control components in the elevator safety protection system. When the elevator car overspeeds or even falls due to any reason during operation, and all other safety protection devices fail to function, the speed governor and safety brake will work together to stop the elevator car.

[0003] An existing patent (publication number: CN212076078U) discloses an adjustable mounting base for an elevator speed governor, belonging to the field of elevator accessories technology. It includes a base and an adjusting plate. The upper surface of the base has a groove, within which the adjusting plate is located. A first slit is provided in the middle of the front and rear side walls of the groove. An adjusting screw is fixed to both the front and rear side walls of the adjusting plate, with its end extending through the first slit. A fastening nut is screwed onto the adjusting screw. A second slit is provided in the middle of the left and right side walls of the groove. A telescopic rod is fixed to both the left and right side walls of the adjusting plate, with its end extending through the second slit and hinged to a lifting plate. A horizontally mounted mounting plate is fixed to the lower part of both the left and right side walls of the base. A lifting screw is rotatably mounted on the mounting plate, extending upwards through the lifting plate. This adjustable mounting base for the elevator speed governor solves the problem of adjusting the angle and height of the elevator speed governor, and is easy to operate.

[0004] While the device in the aforementioned comparative document solves the problem of difficulty in adjusting the angle and height of the speed governor, it is very cumbersome, time-consuming, and laborious to adjust the height of the speed governor. In addition, the device lacks a protective mechanism, making it inconvenient to protect the adjusting components from dust. To solve the above problems, a side-mounted explosion-proof elevator speed governor installation structure is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an installation structure for a side-mounted explosion-proof elevator speed governor, which has advantages such as adjustment function and protective mechanism. It solves the problem that adjusting the height of the speed governor is very cumbersome, time-consuming and laborious, and it is inconvenient for people to protect the adjustment components from dust.

[0006] To achieve the above objectives, this application provides the following technical solution: an installation structure for a side-mounted explosion-proof elevator speed governor, comprising a speed governor body, a mounting base, and a mounting frame, wherein the speed governor body is mounted on the top of the mounting frame, and the mounting frame is slidably connected to the top of the mounting base; The mounting base has two fixed cylinders fixedly connected to its top. Two rotating rods are tightly nested inside the mounting base via bearings at its bottom. An adjusting threaded rod is fixedly connected to the top of each rotating rod, and an adjusting threaded cylinder is threadedly connected to the surface of the adjusting threaded rod. The adjusting threaded cylinder is slidably connected inside the fixed cylinders. Multiple fixed plates are fixedly connected to the bottom of the mounting frame. The top of the adjusting threaded cylinder is fixedly connected between two fixed plates. A worm gear is fixedly connected to the surface of the rotating rod. A transmission rod is tightly nested inside the mounting base via bearings on its inner side. Two worms are fixedly connected to the surface of the transmission rod, and the worms mesh with the worm gears. One end of the transmission rod rotates through the side of the mounting base and is fixedly connected to a first knob. A folding sleeve is fixedly connected between the mounting frame and the mounting base, and the adjusting threaded cylinder is located within the folding sleeve.

[0007] With the above scheme, when the height of the speed limiter body needs to be adjusted using the first knob, people can rotate both first knobs simultaneously to rotate the transmission rod and worm gear. Through the meshing of the worm gear and worm wheel, the rotating rod and adjusting threaded rod can be rotated. Then, through the limiting groove and the limiting block, the position of the adjusting threaded cylinder on the surface of the adjusting threaded rod can be moved. After the adjustment is completed, it is convenient for people to adjust the height of the speed limiter body. The adjustment is very convenient. The folding sleeve covering the adjustment structure can prevent dust from entering.

[0008] Furthermore, a limiting groove is formed on the inner side of the fixed cylinder, and a limiting block is fixedly connected to the surface of the adjusting threaded cylinder, with the limiting block slidably connected within the limiting groove.

[0009] The above scheme uses a limit block that slides within a limit groove. The sliding fit between the limit block and the limit groove prevents the adjusting screw cylinder from shifting during rotation, ensuring a stable lifting process.

[0010] Furthermore, the top of the mounting frame is provided with a mounting groove, and the bottom of the speed limiter body is fixedly connected with a mounting plate, which is snapped into the mounting groove.

[0011] The above solution simplifies the connection between the speed limiter body and the mounting frame through the snap-fit ​​structure between the mounting plate and the mounting slot.

[0012] Furthermore, a U-shaped movable groove is provided inside the mounting frame, the mounting groove is located within the U-shaped movable groove, and mounting holes are provided on both opposite sides of the mounting plate.

[0013] The above solution, by setting a U-shaped movable groove, can provide storage and snap-fit ​​for the rotating shaft, the first screw, the second screw, and the L-shaped mounting block.

[0014] Furthermore, a rotating shaft is tightly nested inside the U-shaped movable groove via bearings. A second knob and a first screw are fixedly connected to both ends of the rotating shaft, and a second screw is fixedly connected to one end of the first screw. The shaft end of the second screw is rotatably connected to the inner side of the U-shaped movable groove.

[0015] With the above solution, by setting a second knob, people can rotate the second knob to drive the first screw and the second screw to rotate, which can provide power for the movement of the L-shaped mounting plate.

[0016] Furthermore, both the first screw and the second screw are threadedly connected to a screw cylinder, and an L-shaped mounting block is fixedly connected to the surface of the screw cylinder. The side of the L-shaped mounting block slides through the U-shaped movable groove and is engaged in the mounting hole.

[0017] With the above scheme, the rotation can be converted into the movement of two L-shaped mounting blocks by the meshing of two screws with the first and second screws. This allows the L-shaped mounting blocks to be pushed into the mounting holes, enabling quick locking or releasing.

[0018] Furthermore, a fixing ring is fixedly connected to the surface of the second knob, a stabilizing threaded cylinder is fixedly connected to the bottom of the mounting frame, a stabilizing bolt is threadedly connected to the surface of the fixing ring, and one end of the stabilizing bolt is threadedly connected inside the stabilizing threaded cylinder.

[0019] With the above solution, by setting a stabilizing bolt and a stabilizing threaded cylinder, after the speed limiter body is installed, one end of the stabilizing bolt is threaded into the stabilizing threaded cylinder. After the connection is completed, the position of the two L-shaped mounting blocks can be stabilized, which can prevent the speed limiter body from shifting position during operation.

[0020] Furthermore, the mounting base has two mounting ears fixedly connected to each of its opposite sides.

[0021] The above solution, by setting mounting ears, can provide multi-point fixation, thereby enhancing the stability of the overall structure.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This side-mounted explosion-proof elevator speed governor installation structure allows for height adjustment via a first knob. Simultaneous rotation of both first knobs causes the transmission rod and worm gear to rotate. The worm gear meshes with the worm wheel, driving the rotating rod and adjusting threaded rod to rotate. The limiting groove and limiting block then position the adjusting threaded cylinder on the adjusting threaded rod surface. After adjustment, the height of the speed governor can be easily adjusted. A folding sleeve covering the adjustment structure prevents dust intrusion. The side-mounted horizontal installation mechanism allows the speed governor to be located in the hoistway machine room, eliminating the need to climb to the top of the hoistway and significantly reducing maintenance difficulty and risk.

Multiple fixed plates 3012 are fixedly connected to the bottom of the mounting frame 3. The top of the adjusting threaded cylinder 206 is fixedly connected between two fixed plates 3012. A worm gear 204 is fixedly connected to the surface of the rotating rods 203. A transmission rod 2010 is tightly nested inside the side of the mounting base 2 via bearings. Two worms 2011 are fixedly connected to the surface of the transmission rod 2010, meshing with the worm gear 204. One end of the transmission rod 2010 rotates through the side of the mounting base 2 and is fixedly connected to a first knob 2012. A folding sleeve 209 is fixedly connected between the mounting frame 3 and the mounting base 2. The adjusting threaded cylinder 206 is located within the folding sleeve 209 and is controlled by the first knob 2012. 012. When the height of the speed limiter body 1 needs to be adjusted, the two first knobs 2012 are rotated simultaneously to rotate the transmission rod 2010 and the worm gear 2011. Through the meshing of the worm gear 2011 and the worm wheel 204, the rotating rod 203 and the adjusting threaded rod 205 can be rotated. Then, through the limiting groove 207 and the limiting block 208, the position of the adjusting threaded cylinder 206 on the surface of the adjusting threaded rod 205 can be adjusted. After the adjustment is completed, it is convenient for people to adjust the height of the speed limiter body. The height of the adjustable cylinder 206 can be adjusted very easily. The adjustment structure is wrapped by the folding sleeve 209 to prevent dust from entering. The inner side of the fixed cylinder 202 has a limit groove 207. The surface of the adjusting threaded cylinder 206 is fixedly connected to the limit block 208. The limit block 208 is slidably connected in the limit groove 207. The sliding cooperation between the limit block 208 and the limit groove 207 prevents the adjusting threaded cylinder 206 from deviating when rotating, ensuring the stability of the lifting process.

[0027] Please see Figure 2 , Figure 3 and Figure 5The mounting frame 3 has a mounting groove 301 at its top, and a mounting plate 101 is fixedly connected to the bottom of the speed limiter body 1. The mounting plate 101 is snapped into the mounting groove 301. The snap-fit ​​structure between the mounting plate 101 and the mounting groove 301 simplifies the connection between the speed limiter body 1 and the mounting frame 3. The mounting frame 3 has a U-shaped movable groove 302 inside, and the mounting groove 301 is located within the U-shaped movable groove 302. Mounting holes 102 are provided on both sides of the mounting plate 101. By setting the U-shaped movable groove 302, a storage clip can be provided for the rotating shaft 303, the first screw 305, the second screw 306, and the L-shaped mounting block 308. Next, a rotating shaft 303 is tightly nested inside the U-shaped movable groove 302 via bearings. A second knob 304 and a first screw 305 are fixedly connected to both ends of the rotating shaft 303, respectively. A second screw 306 is fixedly connected to one end of the first screw 305. The shaft end of the second screw 306 is rotatably connected to the inner side of the U-shaped movable groove 302. By rotating the second knob 304, the first screw 305 and the second screw 306 can be driven to rotate, providing power for the movement of the L-shaped mounting plate 101. Both the first screw 305 and the second screw 306 are threaded with screw cylinders 307. An L-shaped mounting block 308 is fixedly connected to the surface of the screw cylinder 307. The side of the L-shaped mounting block 308 slides through the U-shaped movable groove 302 and is engaged in the mounting hole 102. Through the engagement of the two screw cylinders 307 with the first screw 305 and the second screw 306, the rotation can be converted into the movement of the two L-shaped mounting blocks 308, which can push the L-shaped mounting blocks 308 into the mounting hole 102, enabling quick locking or releasing. A retaining ring 309 is fixedly connected to the surface of the second knob 304. A stabilizing threaded cylinder 3010 is fixedly connected to the bottom of the mounting frame 3. A stabilizing bolt is threadedly connected to the surface of the retaining ring 309. 3011, one end of the stabilizing bolt 3011 is threaded into the stabilizing threaded cylinder 3010. By setting the stabilizing bolt 3011 and the stabilizing threaded cylinder 3010, after the speed limiter body 1 is installed, one end of the stabilizing bolt 3011 is threaded into the stabilizing threaded cylinder 3010. After the connection is completed, the positions of the two L-shaped mounting blocks 308 can be stabilized, which can prevent the speed limiter body 1 from shifting during operation. The mounting base 2 has two mounting ears 201 fixedly connected to each side. By setting the mounting ears 201, multiple points of fixation can be provided, which can enhance the stability of the overall structure.

[0028] In this embodiment, when the height of the speed governor body 1 needs to be adjusted using the first knob 2012, both first knobs 2012 are rotated simultaneously, causing the transmission rod 2010 and worm gear 2011 to rotate. Through the meshing of the worm gear 2011 and the worm wheel 204, the rotating rod 203 and the adjusting threaded rod 205 can be rotated. Then, through the limiting groove 207 and the limiting block 208, the position of the adjusting threaded cylinder 206 on the surface of the adjusting threaded rod 205 can be adjusted. After the adjustment is completed, it is convenient for people to adjust the height of the speed governor body 1. The adjustment is very convenient. The folding sleeve 209 can prevent dust from entering. Through the side-mounted horizontal installation mechanism, the speed governor body 1 can be located on the hoistway machine room floor without climbing to the top of the hoistway, which greatly reduces the difficulty and risk of maintenance.

[0029] The working principle of the above embodiment is as follows: In use, the mounting base 2 is installed in a suitable position using the prepared bolts. After installation, the speed limiter body 1 is placed at the bottom of the mounting frame 3, and the mounting plate 101 is inserted into the mounting groove 301. After insertion, the second knob 304 is rotated to rotate the shaft 303, the first screw 305, and the second screw 306. This causes the two screw cylinders 307 to move closer or further apart from each other on the surfaces of the first screw 305 and the second screw 306, thereby adjusting the position of the two L-shaped mounting blocks 308. The two L-shaped mounting blocks 308 are snapped into the mounting holes 102. After snapping, it is convenient for people to install the speed limiter body 1. After installation, the device can be used. After the speed limiter body 1 is installed, one end of the stabilizing bolt 3011 is threaded into the stabilizing threaded cylinder 3010. After the connection is completed, the positions of the second knob 304, the rotating shaft 303, the first screw 305 and the second screw 306 can be stabilized, thereby stabilizing the positions of the two L-shaped mounting blocks 308 and preventing the speed limiter body 1 from shifting during operation. When the height of the speed limiter body 1 needs to be adjusted, people simultaneously rotate the two first knobs 2012 to rotate the transmission rod 2010 and the worm gear 2011. Through the meshing of the worm gear 2011 and the worm wheel 204, the rotating rod 203 and the adjusting threaded rod 205 can be rotated. Then, through the limiting groove 207 and the limiting block 208, the position of the adjusting threaded cylinder 206 on the surface of the adjusting threaded rod 205 can be driven. After the adjustment is completed, it is convenient for people to adjust the height of the speed limiter body 1. The adjustment is very convenient.
