Description

Technical Field

[0001] This utility model relates to the field of railway loading, and in particular to a railway loading rapid positioning device. Background Technology

[0002] According to railway loading requirements, vehicles and equipment must be centered on the loading platform, and the distance between the two sides of oversized equipment must be equal with an error of less than centimeters. It is difficult for drivers and guides to control the dimensions accurately based on their senses alone. The traditional railway loading mode can only be achieved by manually guiding the vehicle into place and then having the positioning personnel repeatedly adjust and measure it. This process is time-consuming and consumes human resources. In particular, it is more prone to errors when encountering natural conditions such as fog, rain, or night. If the operation is not done properly, it can easily lead to loss of personnel and equipment. Utility Model Content

The first arm is connected to the outer shell of the cable reel, and the end of the first arm is hinged to the first arm of the second arm.

[0008] The sliding part is provided in two parts, which are respectively mounted on two supports and move left and right. The rope of the cable reel is connected to the side of the sliding part. The two sliding parts are driven by the two cable reels respectively, and the rope of the cable reel is detachably connected to the sliding part.

[0009] A laser locator is provided, wherein two laser locators are respectively disposed on the upper surface of the two sliding parts, and the laser locators are used to emit positioning lasers;

When the first support arm and the second support arm are rotated and unfolded to the horizontal, and the positioning mechanism is placed on the upper surface of the loading plate, the housing of the reel, the first ear seat and the second ear seat are all placed on the upper surface of the loading plate.

[0016] As a further improvement, the end of the rope connected to the sliding part is provided with a connector, and the end face of the connector is provided with a screw, which is threadedly connected to the rope hole on the surface of the sliding part.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0032] As attached Figure 1 and Figure 2As shown, a railway loading rapid positioning device includes a positioning mechanism 2 mounted on a loading plate 1. The positioning mechanism 2 includes a cable reel 21, a bracket 22, a sliding part 23, a laser positioner 24, a fastener 25, and a hook spring 26. Two cable reels 21 are provided, and the two cable reels 21 are linked together. Two brackets 22 are respectively located on both sides of the two cable reels 21, and two sliding parts 23 are respectively located on the two brackets 22 and move left and right. The two sliding parts 23 are driven by the two cable reels 21, and the rope 213 of the cable reel 21 is connected to the side of the sliding part 23. Furthermore, a laser positioner 24 is provided on the upper surface of each of the two sliding parts 23, and the laser positioner 24 is used to emit a positioning laser. In use, the cable reel 21 and bracket 22 are centered on the upper surface of the loading plate 1. Then, the cable reel 21 drives the sliding part 23 to slide on the bracket 22 according to the size of the vehicle equipment being loaded, until it moves into place. Then, two laser positioners 24 project positioning lasers onto the upper surface of the loading plate 1 to determine the positioning range. At this time, the vehicle equipment can refer to the positioning laser to judge the deviation range of the vehicle equipment and correct its driving direction to ensure that the vehicle equipment can be accurately loaded into the predetermined position without secondary adjustments, effectively saving manpower and time costs, and overcoming human error caused by extreme weather. Among them, the two cable reels 21 are linked to each other, so that when the cable reel 21 pulls the sliding part 23 and adjusts the laser positioners 24, it can always keep the two laser positioners 24 axially symmetrical and centered on the loading plate 1.

[0033] Preferably, as shown in the appendix Figure 3 As shown, the two cable reels 21 are synchronously driven by a dual-axis motor 211 and are linked together. Specifically, the dual-axis motor 211 is located between the housings 218 of the two cable reels 21. The turntables inside the housings 218 of the two cable reels 21 are respectively connected to the two motor shafts of the dual-axis motor 211. The dual-axis motor 211 synchronously drives the two turntables to rotate, so that the two cable reels 21 start and stop synchronously. During the process, the turntables wind up the rope 213 or unwind the rope 213 to ensure that the two laser positioners 24 are axially symmetrical and centered on the loading plate 1. The two ends of the turntables are connected to the surface of the housing 218 through bearings.

[0034] Further details are attached. Figure 1 and Figure 2As shown, the laser positioner 24 features a dual-laser design, specifically consisting of two lasers. These two lasers emit two beams of laser light, projecting two positioning laser beams onto each side of the upper surface of the loading plate 1. During loading, the vehicle is positioned so that the outer edge of its tires is tangent to the inner positioning laser lines of the two laser positioners, ensuring the vehicle remains centered on the loading plate 1. If the vehicle deviates from its intended position, as long as the outer edge of the tires remains between the two laser lines of the laser positioner 24, the deviation requirement is met, and the loading balance is not affected. Furthermore, the laser positioner 24 and the sliding part 23 are detachably connected; specifically, both lasers of the laser positioner 24 are bolted to the sliding part 23. If one laser positioner 24 malfunctions, the two lasers of the other laser positioner 24 can be separated and installed on the two sliding parts 23 respectively for reference in determining the vehicle's center position.

[0035] It is worth mentioning that, as shown in the attached document Figure 4 , Figure 5 and Figure 10 As shown, the bracket 22 includes a first arm 221 and a second arm 222. The first arm 221 is connected to the housing 218 of the reel 21 at its head end. The first arm 221 is hinged to the head end of the second arm 222 at its tail end. Specifically, the lower surface of the tail end of the first arm 221 is provided with a downwardly protruding first ear seat 2211, and the lower surface of the head end of the second arm 222 is provided with a downwardly protruding second ear seat 2221. The second ear seat 2221 is hinged to the first ear seat 2211. When the first arm 221 and the second arm 222 rotate and unfold to a horizontal position, and the positioning mechanism 2 is placed on the upper surface of the loading plate 1, the outer shell 218 of the reel 21, the first ear seat 2211, and the second ear seat 2221 are all placed on the upper surface of the loading plate 1. At this time, on the one hand, the first ear seat 2211 and the second ear seat 2221 assist in supporting the positioning mechanism 2, making the installation of the positioning mechanism 2 more stable; on the other hand, the loading plate 1 is used to spread the first arm 221 and the second arm 222, so that the first arm 221 and the second arm 222 can be kept horizontal and do not affect the use. After the positioning mechanism 2 is used, it can be removed from the loading plate 1, and then the first arm 221 and the second arm 222 can be folded to reduce the size of the positioning mechanism 2 and facilitate its storage.

[0036] Among them, as attached Figure 4 and Figure 5As shown, both the first arm 221 and the second arm 222 have slide rails 225 on their sides. When rotated and unfolded to a horizontal position, the slide rails 225 on the first arm 221 and the second arm 222 are connected to each other. A slider 226 is provided at the bottom of the sliding part 23. This slider 226 slides left and right around the outside of the slide rail 225. The guide and restraint provided by the slide rail 225 allows the sliding part 23 to move smoothly left and right on the bracket 22. Furthermore, the first end of the first arm 221 is detachably connected to the outer casing 218 of the cable reel 21. Specifically, the surface of the outer casing 218 is provided with a C-shaped connector 212, which extends from the side of the outer casing 218. The C-shaped connector 212 is connected to the first end of the first arm 221 by bolts, facilitating the replacement of subsequent positioning mechanism 2 parts.

[0037] The first arm 221 and the second arm 222, when rotated and unfolded to a horizontal position, are fixed by connecting screws 227. Specifically, the upper surface of the end of the first arm 221 has a downwardly recessed connecting groove 2212, the bottom of which has a first connecting hole 2213. The upper surface of the beginning of the second arm 222 has an outwardly protruding connecting part 2222, which passes through the second connecting hole 2223. When the first arm 221 and the second arm 222 are rotated and unfolded to a horizontal position, the connecting part 2222 is placed into the connecting groove 2212, and the first connecting hole 2213 is aligned with the second connecting hole 2223. Then, by screwing the connecting screws 227 into the second connecting hole 2223 and the first connecting hole 2213, the first arm 221 and the second arm 222 are fixed, preventing them from loosening during use and affecting their operation. Before folding the bracket 22, simply remove the connecting screws 227.

[0038] Furthermore, the upper surface of the connecting part 2222 is provided with a downwardly recessed countersunk hole 2224. The countersunk hole 2224 surrounds the second connecting hole 2223. When the connecting screw 227 is screwed into the second connecting hole 2223 and the first connecting hole 2213, the head of the connecting screw 227 is placed in the countersunk hole 2224, so as to prevent the connecting screw 227 from protruding and obstructing the sliding part 23.

[0039] Additionally, as attached Figure 3 and Figure 4As shown, the rope 213 of the reel 21 is detachably connected to the sliding part 23. Specifically, one end of the rope 213 connected to the sliding part 23 is provided with a connector 214, and the end face of the connector 214 is provided with a screw 215. The screw 215 is threadedly connected to the rope hole 241 on the surface of the sliding part 23. After the positioning mechanism 2 is used and before the folding bracket 22 is stored, the rope 213 can be removed from the sliding part 23 to avoid excessive pulling of the rope 213, which could cause wear or breakage. Furthermore, the outer shell 218 of the reel 21 is provided with a guide plate 216, and the surface of the guide plate 216 has a guide groove 217. The rope 213 of the reel 21 passes through the guide groove 217 and connects to the connector 214. The diameter of the connector 214 is larger than the width of the guide groove 217. The guide groove 217 guides the rope 213, ensuring that the rope 213 can be smoothly wound up and unwound.

[0040] Meanwhile, as attached Figure 4 As shown, a hook spring 26 is provided between the second support arm 222 and the sliding part 23. The two ends of the hook spring 26 are respectively connected to the second support arm 222 and the sliding part 23. Specifically, hook rings 224 are provided on the side of the side plate 223 and the side of the sliding part 23. The two ends of the hook spring 26 are detachably hooked onto the two hook rings 224. When the rope 213 pulls the sliding part 23 to move, the stretched hook spring 26 can tighten the sliding part 23 and prevent the sliding part 23 from moving freely on the support 22.

[0041] In addition, as attached Figure 1 ,as well as Figures 6 to 9As shown, the positioning mechanism 2 is detachably mounted on the upper surface of the loading plate 1 via fasteners 25. Two fasteners 25 are respectively located at the ends of the two second supports 222, and the fasteners 25 are movably connected to the second supports 222. Specifically, the upper surface of the end of the second support 222 has an upwardly protruding side plate 223. Each side of the side plate 223 has a first mounting portion 2231, and a positioning pin 2232 is provided between the two first mounting portions 2231. The two ends of the positioning pin 2232 are respectively connected to the surfaces of the two first mounting portions 2231. A positioning groove 251 penetrates the side of the fastener 25. The positioning groove 251 is an oblong groove, and the positioning pin 2232 passes through the positioning groove 251. The fastener 25 is sleeved on the outside of the positioning pin 2232 and moves. The two sides of the end of the second support arm 222 are provided with second mounting parts 228. The second mounting parts 228 are located below the first mounting parts 2231, and a cam 229 is provided between the two second mounting parts 228. The two end faces of the cam 229 are provided with coaxial rotating pins 2291. The rotating pins 2291 are located on the side of the second mounting parts 228 and rotate. The rotating pins 2291 are eccentrically set on the cam 229 to form a pressing part 2292. When the positioning mechanism 2 is centered on the loading plate 1, the fastener 25 is moved downwards around the positioning pin 2232 and rotated to both sides of the loading plate 1. Then, the cam 229 is rolled. During this process, the clamping part 2292 presses the fastener 25 against the side of the loading plate 1. At this time, the two fasteners 25 clamp the two sides of the loading plate 1, thereby fixing the positioning mechanism 2 on the loading plate 1 and preventing the positioning mechanism 2 from shifting under force during use. When the positioning mechanism 2 is not needed, the cam 229 can be rotated to loosen the fastener 25 from the loading plate 1, and the positioning mechanism 2 can then be removed from the loading plate 1.

[0042] As attached Figure 6 and Figure 10 As shown, when folding the bracket 22, the fastener 25 can be moved downward around the positioning pin 2232 and rotated onto the second arm 222. This can prevent the fastener 25 from hitting the reel 21 and further reduce the size of the positioning mechanism 2 for easy storage.

[0043] Preferably, as shown in the appendix Figure 7 As shown, a handle 2293 is provided on the circumferential surface of the cam 229. The handle 2293 is used to rotate the cam 229 to realize the installation and removal of the positioning mechanism 2. Furthermore, the fastener 25 has an inwardly recessed clamping groove 252 on the side near the cam 229. The cam 229 slides along the clamping groove 252. The groove wall of the clamping groove 252 further guides and limits the cam 229, preventing the cam 229 from tilting during rolling and affecting its use.

[0044] In summary, when using this invention, the cable reel 21 and the bracket 22 are centered on the upper surface of the loading plate 1. Then, the cable reel 21 drives the sliding part 23 to slide on the bracket 22 according to the size of the loaded vehicle equipment until it moves into place. Then, two laser positioners 24 project positioning lasers onto the upper surface of the loading plate 1 to determine the positioning range. At this time, the vehicle equipment can refer to the positioning laser to judge the deviation range of the vehicle equipment and correct its driving direction to ensure that the vehicle equipment can be accurately loaded into the predetermined position without secondary adjustments, effectively saving manpower and time costs, and overcoming human error caused by extreme weather. After the positioning mechanism 2 is used, the first arm 221, the second arm 222 and the fastener 25 of the positioning mechanism 2 can be folded to reduce the size of the positioning mechanism 2 and facilitate its storage.

[0045] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
