Description
Technical Field
[0001] This utility model belongs to the field of vehicle stopper technology, specifically relating to an in-cage vehicle stopper based on gear and rack transmission. Background Technology
[0002] The cage-mounted trolley blocker is a safety protection device installed at the bottom of the elevator car. It is mainly used to prevent trolleys, goods, etc. transported inside the car from sliding or shifting when the elevator is running or starting and stopping, thus ensuring the safety of elevator operation and passengers. Its core function revolves around safety protection. By using blocking structures or friction components, it limits the movement range of trolleys and goods, thereby avoiding collisions with the car walls or crushing of people due to inertia. It is made of high-strength steel or wear-resistant materials and has impact resistance and corrosion resistance, so it can work stably for a long time under the condition of frequent elevator start and stop.
[0003] Currently, existing cage-mounted vehicle stoppers typically limit the movement of the transported handcarts by using the height difference (similar to speed bumps). However, while traditional cage-mounted vehicle stoppers can prevent handcarts from sliding to some extent, when the car experiences bumps, the handcarts may slide off the speed bumps, thus reducing safety. Utility Model Content
[0004] The purpose of this invention is to provide a cage-mounted vehicle stop based on gear and rack transmission, which aims to solve the problem that existing cage-mounted vehicle stops in use usually limit the transported handcarts by the height difference (similar to speed bumps). However, although traditional cage-mounted vehicle stops can prevent handcarts from sliding to a certain extent, when the car bumps, the handcarts may slide and rush out of the speed bump, thus reducing safety.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cage-type vehicle stopper based on gear and rack transmission, comprising two support seats, a track installed on the top of the two support seats, a partition fixedly connected to the inner wall of the two support seats, a double-headed motor installed at the bottom of the partition, and a lead screw connected to the output end of the double-headed motor; The lead screw is threadedly connected to a threaded sleeve on its outer wall. A connecting block is fixedly connected to the top of the threaded sleeve. A rack is fixedly connected to the top of the connecting block. Two gears are rotatably connected to the inner walls of the two support seats. A connecting frame is fixedly connected to the sides of the two gears. A stop block is fixedly connected to one end of the connecting frame. A control switch is installed at the end of the support seat.
[0006] As a preferred embodiment of the rack and pinion drive-based in-cage brake of this utility model, the rack and gear mesh with each other.
[0007] As a preferred embodiment of the gear and rack transmission-based cage-type vehicle stopper of this utility model, the bottom of the threaded sleeve is fixedly connected to a guide slider, and two guide rails are installed on the inner bottom of the two support seats.
[0008] As a preferred embodiment of the gear and rack transmission-based cage-type vehicle stopper of this utility model, the threaded sleeve can form a sliding connection structure with the support base through the guide slider and the guide rail.
[0009] As a preferred embodiment of the gear and rack transmission-based cage-type vehicle stopper of this utility model, a rubber block is connected to the surface of the vehicle stop block, a mounting slider is fixedly connected to the back of the rubber block, and a mounting groove is provided on the outer wall of the vehicle stop block.
[0010] As a preferred embodiment of the gear and rack transmission-based in-cage vehicle stopper of this utility model, the cross-section of the mounting slider and the mounting groove is "T" shaped.
[0011] As a preferred embodiment of the gear and rack transmission-based cage-type vehicle stopper of this utility model, the rubber block can form a sliding connection structure with the vehicle stop block through the installation slider and the installation groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are: By pushing the trolley rollers along the track, and then using a double-headed motor to drive the lead screws at both ends to rotate clockwise, the two threaded sleeves connected to the outer walls of the lead screws at both ends can move in opposite directions along the guide rail under the action of the guide slider. At the same time, the top of the connecting block will move in opposite directions along the two drive racks. Then, by using the meshing relationship between the racks and gears, the gears can drive the connecting frame to rotate until the stop block is set on the top of the track. Thus, the stop block can limit the trolley rollers on the track, thereby further improving stability and safety.
[0013] By using the mounting slider on the back of the rubber block, slide the mounting slider into the mounting groove on the outer wall of the barrier block until the rubber block is placed on the surface of the barrier block. In this way, the properties of the rubber block can play a buffering role when the trolley roller contacts the barrier block. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-4 The present invention provides the following technical solution: a cage-type vehicle stopper based on gear and rack transmission, comprising two support seats 1, a rail 2 installed on the top of the two support seats 1, a partition 3 fixedly connected to the inner wall of the two support seats 1, a double-headed motor 4 installed at the bottom of the partition 3, and a lead screw 5 connected to the output end of the double-headed motor 4. The outer wall of the lead screw 5 is threaded with a threaded sleeve 6, the top of the threaded sleeve 6 is fixedly connected with a connecting block 7, the top of the connecting block 7 is fixedly connected with a rack 8, the inner walls of the two support seats 1 are rotatably connected with two gears 9, the sides of the two gears 9 are fixedly connected with a connecting frame 10, one end of the connecting frame 10 is fixedly connected with a stop block 11, and a control switch 15 is installed at the end of the support seat 1. It should be noted that track 2 is level with the bottom of the elevator car. Track 2 is used to position the trolley rollers to be pushed in. When pushing the trolley in, the rollers need to be pushed in along track 2.
[0018] Preferably, the rack 8 and the gear 9 mesh with each other, the bottom of the threaded sleeve 6 is fixedly connected to the guide slider 13, and the inner bottom of the two support seats 1 is equipped with two guide rails 14. The threaded sleeve 6 can form a sliding connection structure with the support seat 1 through the guide slider 13 and the guide rails 14.
[0019] In practical use, the handcart rollers are pushed along the track 12, and then the control switch 15 is used to operate the double-head motor 4 to drive the two lead screws 5 at both ends to rotate clockwise. This allows the two threaded sleeves 6 connected to the outer wall of the lead screws 5 at both ends to move in opposite directions along the guide slide rail 14 under the action of the guide slider 13. At the same time, the top of the connecting block 7 will drive the two racks 8 to move in opposite directions together. Then, the meshing relationship between the racks 8 and the gears 9 will allow the gears 9 to drive the connecting frame 10 to rotate until the stop block 11 is mounted on the top of the track 2. Thus, the stop block 11 can limit the handcart rollers on the track 2, thereby further improving stability and safety. Conversely, by using the control switch 15 to operate the dual-head motor 4 to drive the two lead screws 5 at both ends to rotate counterclockwise, the two threaded sleeves 6 connected to the outer wall of the lead screws 5 at both ends can move towards each other along the guide rail 14 under the action of the guide slider 13. At the same time, the top of the connecting block 7 will drive the two racks 8 to move towards each other. Then, by using the meshing relationship between the rack 8 and the gear 9, the gear 9 can drive the connecting frame 10 to rotate in the opposite direction until the stop block 11 flips over and is stored in the support seat 1. At this time, the trolley on the track 2 can be moved. It should be noted that the wiring terminals of the dual-head motor 4 are connected to the control switch 15 and the external power supply.
[0020] Preferably, a rubber block 12 is connected to the surface of the stop block 11, and a mounting slider 16 is fixedly connected to the back of the rubber block 12. A mounting groove 17 is provided on the outer wall of the stop block 11. The cross-section of the mounting slider 16 and the mounting groove 17 is "T" shaped. The rubber block 12 can form a sliding connection structure with the stop block 11 through the mounting slider 16 and the mounting groove 17.
[0021] In practical use, the mounting slider 16 on the back of the rubber block 12 is slid into the mounting groove 17 on the outer wall of the barrier block 11 until the rubber block 12 is placed on the surface of the barrier block 11. Thus, the properties of the rubber block 12 can play a buffering role when the trolley roller contacts the barrier block 11.
[0022] Working principle: First, the cage-mounted car stopper of this application is installed at the bottom of the elevator car. The mounting slider 16 on the back of the rubber block 12 is slid into the mounting groove 17 on the outer wall of the car stop block 11 until the rubber block 12 is placed on the surface of the car stop block 11. At this point, the handcart roller is pushed in along the track 12. Then, the control switch 15 operates the double-headed motor 4 to drive the two lead screws 5 at both ends to rotate clockwise. This causes the two threaded sleeves 6 connected to the outer walls of the lead screws 5 to move in opposite directions along the guide rail 14 under the action of the guide slider 13. Simultaneously, the top of the connecting block 7 will cause the two drive racks 8 to move in opposite directions together. Then, the meshing relationship between the racks 8 and the gears 9 allows the gears 9 to drive the connecting frame 10 to rotate until the car stop block 11 is mounted on the track. The top of track 2 is blocked by a stop block 11, which limits the trolley rollers on track 2, thereby improving stability and safety. The rubber block 12 acts as a buffer when the trolley rollers contact the stop block 11. Finally, the control switch 15 controls the double-headed motor 4 to drive the two lead screws 5 at both ends to rotate counterclockwise. This causes the two threaded sleeves 6 connected to the outer wall of the lead screws 5 to move towards each other along the guide rail 14 under the action of the guide slider 13. At the same time, the top of the connecting block 7 will drive the two racks 8 to move towards each other. Then, the meshing relationship between the racks 8 and the gears 9 will cause the gears 9 to drive the connecting frame 10 to rotate in the opposite direction until the stop block 11 flips over and is stored in the support seat 1. At this time, the trolley on track 2 can be moved.
[0023] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
