Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, specifically a vehicle collision avoidance device. Background Technology
[0002] Overhead cranes are large mechanical devices used in factories, docks, shipyards, and other places for lifting materials. They can move horizontally on a cable tray and, with the help of a lifting mechanism, complete the vertical transportation of goods, making them an important component of manufacturing. Currently, overhead cranes used in factories only have limit switches at the ends of the cable trays. However, in actual production, other equipment that may interfere with the crane may inevitably appear in the middle of the cable tray due to actual factory needs. If workers operate the overhead crane incorrectly, it can easily collide with other objects, significantly reducing the crane's service life and potentially causing serious engineering accidents that threaten personnel safety. Utility Model Content
[0003] The purpose of this invention is to provide a vehicle collision avoidance device to solve the problems currently existing in the market as described in the background.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a vehicle collision avoidance device, comprising:
[0005] The anti-collision mechanism is fixed across the cable tray rail and has an extension extending from it to engage with the travel switch on the trolley. The travel switch on the trolley contacts the extension to initiate active braking.
[0006] A buffer mechanism is provided to buffer the failure of the travel limit switch.
[0007] Preferably, the anti-collision mechanism includes a support body welded to the cable tray track, and the extension consists of an extension bracket fixed to the support body and a touch plate installed at the end of the extension bracket;
[0008] The buffer mechanism includes a buffer column welded to the cable tray track and a buffer pad A on the buffer column.
[0009] Preferably, the buffer mechanism further includes a buffer pad B installed on the support body.
[0010] Preferably, the main body of the support consists of two support columns, two inclined support columns connected to the two support columns, and several sets of crossbars for connecting the two support columns. The support columns and the inclined support columns are welded to the cable tray track for fixation.
[0011] Preferably, a traction bracket is also welded onto the extension bracket, and the ends of the extension bracket and the traction bracket away from the touch plate are connected to the two crossbars near the top.
[0012] Preferably, a set of buffer pads B is provided on each of the two supporting columns.
[0013] Preferably, the buffer column consists of a mounting plate for mounting the buffer pad A and an inclined plate perpendicular to the back of the mounting plate; the mounting plate and the inclined plate are integrally welded to the cable tray track.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model works in conjunction with the limit switch on the crane. When the limit switch fails, it can also be physically stopped by the buffer pad. At the same time, the overall structure is a frame mechanism, which eliminates the need to install sensors on the device for electrical connection, thus reducing the overall weight.

[0020] 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.
[0021] Please see Figures 1-3 This utility model provides a vehicle collision avoidance device, such as... Figure 1 As shown, it includes: an anti-collision mechanism 1 spanning across the cable tray track 3, an extension extending from the anti-collision mechanism 1 to cooperate with the travel limit switch on the trolley, the travel limit switch on the trolley contacting the extension for active braking; and a buffer mechanism 2 for buffering after the travel limit switch on the trolley fails.
[0022] In specific implementation, such as Figure 2 As shown, the anti-collision mechanism 1 includes a support body 101 welded to the cable tray rail 3. The extension part consists of an extension bracket 102 fixed to the support body 101 and a touch plate 103 installed at the end of the extension bracket 102. The installation angle of the touch plate 103 needs to be reasonably adjusted and set by those skilled in the art according to the travel limit switch of the vehicle under actual working conditions. The active braking is achieved by the touch plate 103 contacting the travel limit switch of the vehicle. The buffer mechanism 2 includes a buffer column 201 welded to the cable tray rail 3 and a buffer pad A202 on the buffer column 201. When the travel limit switch fails, it serves as a buffer for physical collisions.
[0023] As a further improvement, the buffer mechanism 2 also includes a buffer pad B203 installed on the bracket body 101, which serves as a buffer against physical collisions when the limit switch fails.
[0024] As further explained: The main body 101 of the support consists of two support columns 10101, an inclined support column 10102 connected to the two support columns 10101, and several sets of crossbars 10103 used for connecting the two support columns 10101. The support columns 10101 and the inclined support columns 10102 are welded to the cable tray track 3 for fixation, which increases the overall rigidity and makes the device more stable on the cable tray track 3.
[0025] As a further improvement, a traction bracket 104 is also welded onto the extension bracket 102. The end of the extension bracket 102 and the traction bracket 104 away from the touch plate 103 is connected to the two crossbars 10103 near the top, increasing the overall vertical rigidity of the extension.
[0026] As a further improvement, a set of buffer pads B203 are installed on each of the two support columns 10101.
[0027] As a further explanation: Figure 3 As shown, the buffer column 201 consists of a mounting plate 20101 for mounting the buffer pad A202 and an inclined plate 20102 perpendicular to the back of the mounting plate 20101; the mounting plate 20101 and the inclined plate 20102 are welded as a single piece onto the cable tray track 3, increasing the overall vertical rigidity of the extension.
[0028] It should be noted that the buffer pad A202 and / or buffer pad B203 in this embodiment are made of polyurethane material, but are not limited to the above material. Those skilled in the art can make appropriate settings according to actual needs, and will not be described in detail here.
[0029] In practical applications, the trolley travels on two sets of bridge rails 3. When the trolley reaches its limit position, the limit switch on the trolley will contact the contact plate 103 at the front end of the extension bracket 102 and close. The limit switch will send a trigger signal to the trolley controller to brake and stop the trolley. When the limit switch malfunctions or fails, it will be buffered by the buffer pads A202 and B203 made of polyurethane, and the limit will be stopped by physical collision.
[0030] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
