Description

Technical Field

[0001] The utility model relates to the technical field of electric hoists, in particular to an electric hoist trolley with an adaptive track. Background Technique

[0002] The published patent No. CN217478891 discloses an electric hoist trolley with an adaptive track, which includes a motor, a traveling wheel device, and a drum. A rotating ball is arranged at the end of the wheel shaft of the traveling wheel device facing the track, and the rotating ball is embedded in the wheel shaft, and a cover plate is arranged on the wheel shaft to limit the rotating ball. A groove matching the contour of the rotating ball is arranged on the wheel shaft. The rotating ball rolls to avoid the traveling wheels of the traveling wheel device from colliding with the track and deviating during traveling, achieving limitation. Moreover, rolling friction is used instead of sliding friction to reduce resistance and improve the structure. However, the following problems still exist in the actual use of this patent:

[0003] Existing electric hoist trolleys are usually installed on I-beam rails, and the positions of the rollers of the electric hoist trolleys are fixed. Therefore, when installing the electric hoist trolley, I-beam rails of a fixed size must be used. Otherwise, it is easy to cause strong collisions between the trolley and the track. And due to the production errors of the I-beam rails, even for I-beam rails of a specific specification, collisions and deflections will occur between the electric hoist trolley and the I-beam rails. Moreover, a single-size electric hoist trolley can only be applicable to I-beam rails of a single specification and cannot adapt to I-beam rails that are too large or too small, resulting in a low application range of the electric hoist trolley.

[0004] An electric hoist trolley with an adaptive track is proposed to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electric hoist trolley with an adaptive track to solve the problem that a single-size electric hoist trolley can only be applicable to I-beam rails of a single specification, cannot adapt to I-beam rails that are too large or too small, nor can it adapt to the deviations inherent in the production of I-beam rails, resulting in inevitable collisions as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An electric hoist trolley with an adaptive track, including a hoist body, the hoist body includes a rope outlet cylinder, a drum is arranged inside the rope outlet cylinder, a double rope is wound on the drum, one end of the drum is fixedly connected to a disc motor installed outside the rope outlet cylinder, the top of the rope outlet cylinder is fixedly connected to a connecting block, and running car plates are symmetrically arranged on both sides of the top of the connecting block, and an I-beam rail passes through between the running car plates;

[0010] Preferably, the first guide rod and the second guide rod are both slidably connected with a sliding block, the first guide rod and the second guide rod are both provided with a plurality of threaded positioning holes, and screw pins are connected through the threaded positioning holes and the sliding blocks.

[0011] Preferably, one of the driving gears is fixedly connected to a driving motor, the sides of the two driving gears are fixedly connected to upper wheels, a connecting rod is fixedly connected between the two upper wheels, the width of the driving gear is slightly larger than the lower gear, and the bottom of the upper wheel fits against the top surface of the I-rail.

[0012] Preferably, a convex plate is fixedly connected to the side of the moving block, the convex plate is slidably connected to the sliding block, and the spacing between adjacent threaded positioning holes is less than 5 mm.

[0013] Preferably, the first guide rod, the curved groove and the second guide rod are all arc-shaped with the same center, and the center of the first guide rod overlaps with the center of the driving gear.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the electric hoist trolley with adaptive track can change the vertical distance between the upper wheel and the lower wheel through the movable lower wheel, and with the help of the fixing of the screw pin and the threaded positioning hole and the adaptive spring, the upper wheel and the lower wheel can stably fit the I-rail, so that the device can adapt to I-rails of different specifications, increase practicality, and reduce shaking and collision when the trolley moves. The specific contents are as follows:

[0016] 1. During installation, first pull the moving block downward to contract the adaptive spring. Then, slide the lower wheel into the groove of the I-beam rail, and release the moving block to allow the adaptive spring to extend and press against the groove of the I-beam rail. Use a pin and a threaded positioning hole for reinforcement. At this time, the upper wheel will adhere to the top surface of the I-beam rail. If the specifications of the I-beam rail are different, the height of the lower wheel can be reduced so that the device can be applicable to I-beam rails of different specifications. The simultaneous action of the upper wheel and the lower wheel can increase the stability of the device during movement and reduce shaking and collision.

[0017] 2. When the width of the I-beam rail is different, first, the threaded stud can be rotated and moved by bending the wrench, so that there is a slight slip between the lower gear and the driving gear, enabling the lower wheel to stably embed into the groove of the I-beam rail, reducing the width of the gap, and decreasing the degree of skew and shaking of the electric trolley.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: an electric hoist trolley with an adaptive track, including a hoist body 1. The hoist body 1 includes a rope outlet cylinder 101. A drum is arranged inside the rope outlet cylinder 101. A double rope 102 is wound around the drum. One end of the drum is fixedly connected to a disc motor 103 installed outside the rope outlet cylinder 101. The top end of the rope outlet cylinder 101 is fixedly connected to a connecting block 104. On both sides of the top of the connecting block 104, carriage plates 106 are symmetrically arranged. An I-beam 105 passes through between the carriage plates 106;

[0026] A moving component 2 is arranged on the carriage plate 106. The moving component 2 includes driving gears 201 symmetrically installed inside the carriage plate 106. The other side of the driving gear 201 is meshed with a lower gear 204. A moving block 205 is arranged on the side of the lower gear 204. The other side of the lower gear 204 is fixedly connected to a lower wheel 207. The lower wheel 207 is in contact with the I-beam 105;

[0027] Among them, the moving block 205 is slidably connected to the carriage plate 106. An adaptive spring 213 is fixedly connected between the outside of the moving block 205 and the carriage plate 106; the adaptive spring 213 can realize the adaptive adjustment of the lower wheel 207 and the I-beam 105.

[0028] A curved groove 208 is opened on the outside of the carriage plate 106. The curved groove 208 is slidably connected to the moving block 205. A first guide rod 209 and a second guide rod 210 fixedly connected to the carriage plate 106 are respectively arranged on the upper and lower sides of the curved groove 208.

[0029] Sliding blocks 211 are slidably connected to both the first guide rod 209 and the second guide rod 210. A plurality of threaded positioning holes 212 are opened on both the first guide rod 209 and the second guide rod 210. A pin 214 is connected through between the threaded positioning hole 212 and the sliding block 211; after the pin 214 passes through the sliding block 211, it is threadedly connected to the threaded positioning hole 212, so that the problem of the sliding block 211 together with the moving block 205 is roughly fixed, and the adaptive spring 213 can push the position of the moving block 205 to be finely adjusted effectively, and finally the lower wheel 207 is in contact with the I-beam 105.

[0030] A driving gear 201 is fixedly connected to a driving motor 206, and the sides of the two driving gears 201 are fixedly connected to upper wheels 202. A connecting rod 203 is fixedly connected between the two upper wheels 202. The width of the driving gear 201 is slightly larger than the lower gear 204, and the bottom of the upper wheel 202 is in contact with the top surface of the I-rail 105. The connecting rod 203 can enable one driving gear 201 to drive another driving gear 201 to rotate, and the position of the lower gear 204 remains in mesh with the driving gear 201 when fine-tuning.

[0031] A convex plate is fixedly connected to the side of the moving block 205, and the convex plate is slidably connected to the sliding block 211. The spacing between adjacent threaded positioning holes 212 is less than 5 mm; the distance between the threaded positioning holes 212 is smaller than the error between the traditional I-rail 105 and the roller, so that the lower wheel 207 can always fit with the I-rail 105. When the lower wheel 207 fits with the I-rail 105, the position of the sliding block 211 can be fine-tuned so that the sliding block 211, the screw pin 214 and the threaded positioning hole 212 can pass through.

[0032] The first guide rod 209 , the curved groove 208 , and the second guide rod 210 are all arc-shaped with the same center. The center of the first guide rod 209 overlaps with the center of the driving gear 201 , so that the lower gear 204 and the driving gear 201 remain in meshing when the moving block 205 moves.

[0033] A fine-tuning component 3 is provided on the moving block 205, and the fine-tuning component 3 includes a threaded pin 301 embedded in the moving block 205, the threaded pin 301 is threadedly connected to the moving block 205, a bearing 302 is fixedly connected between the other end of the threaded pin 301 and the lower gear 204, the inner ring of the bearing 302 is fixedly connected to one end of the threaded pin 301, and the outer ring of the bearing 302 is fixedly connected to the lower gear 204; the threaded pin 301 can be rotated and moved by a bending wrench, so that a slight sliding occurs between the lower gear 204 and the driving gear 201, so that the lower wheel 207 can be stably embedded in the groove of the I-rail 105 of different widths, reducing the width of the gap and reducing the degree of deflection and shaking of the electric trolley.

[0034] Working principle: Before using this kind of electric hoist trolley with adaptive track, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, during installation, first pull the moving block 205 downward to shrink the adaptive spring 213, then slide the lower wheel 207 into the groove of the I-rail 105, and then release the moving block 205 to extend the adaptive spring 213 and make it abut against the groove of the I-rail 105, and reinforce it with the screw pin 214 and the threaded positioning hole 212, at which time the upper wheel 202 will stick to the top surface of the I-rail 105;

[0035] When the widths of the I-beams 105 are different, first, the threaded stud 301 can be rotated and moved by bending the wrench, so that a slight slip occurs between the lower gear 204 and the driving gear 201, enabling the lower wheel 207 to stably engage in the groove of the I-beam 105;

[0036] When the driving gear 201 starts, the lower gear 204 can be rotated through the driving gear 201, the upper wheel 202 and the connecting rod 203. Finally, under the combined action of the upper wheel 202 and the lower wheel 207, the hoist body 1 can move stably on the I-beam 105.

[0037] 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
