Description

Technical Field

[0002] The gantry crane is a deformation of the bridge crane. In the port, it is mainly used for the loading and unloading operations of outdoor freight yards, material yards, and bulk goods. Its metal structure is like a gantry frame. Two support legs are installed under the load-bearing main beam, and it can directly run on the ground track. The two ends of the main beam can have outstretched cantilever beams. The gantry crane has the characteristics of high site utilization rate, large operation range, wide adaptability, and strong versatility, and is widely used in port freight yards.

[0038] A gantry crane rail clip is proposed for the problem of poor braking effect during the use of the gantry crane rail clip that clamps the rail at a single position in the prior art.

[0039] As Figure 1-8 shown, the gantry crane rail clip of the embodiment of the present utility model is arranged on the rail 4. The gantry crane rail clip includes: a support frame 11, which is arranged above the rail 4 and is slidably assembled with the rail 4 for carrying the clamping member 1. The clamping member 1 includes a linkage part 12 and an adjusting rod 13; a plurality of clamping members 1 are correspondingly arranged on one support frame 11; the linkage part 12 includes a pressing plate 121, a pushing plate 122, a clamping plate 123 and a supporting plate 124. The pushing plate 122 includes a first pushing plate and a second pushing plate, and the first pushing plate and the second pushing plate are symmetrically arranged with respect to the pressing plate 121. The first pushing plate and the second pushing plate are respectively hinged to the pressing plate 121; the clamping plate 123 includes a first clamping plate and a second clamping plate. The first clamping plate is hinged to the first pushing plate, and the second clamping plate is hinged to the second pushing plate. The ends of the first clamping plate and the second clamping plate away from the pushing plate 122 respectively have clamping heads 1231, and the clamping heads 1231 are arranged at positions corresponding to the side walls of the rail 4 for clamping the side walls of the rail 4; the supporting plate 124 is arranged on the support frame 11, one end of the supporting plate 124 is fixedly connected to the first clamping plate, and the other end of the supporting plate 124 is fixedly connected to the second clamping plate; one end of the adjusting rod 13 is connected to the supporting plate 124, and the other end is connected to the pressing plate 121. The adjusting rod 13 is used to lift the pressing plate 121 to adjust the clamping force of the clamping heads 1231 on the side wall of the rail 4.

[0040] Preferably, the side wall of the track 4 has a chute adapted to the chuck 1231; the above setting enables the chute on the side wall of the track 4 to play a role in guiding the chuck 1231, thereby helping to ensure the stability of the gantry crane when it moves or brakes.

[0041] During the use of the rail clamp of the gantry crane in this embodiment (the rail clamp of the gantry crane is connected to the gantry crane and can move with the gantry crane during the movement of the gantry crane. Therefore, when the rail clamp of the gantry crane is fixed on the track 4, the movement of the gantry crane is also braked), when it is necessary to use the clamping member 1 to clamp and fix the track 4 (rail can be used) to brake the gantry crane, the adjusting rod 13 can be extended. Then, the pressing plate 121 moves upward under the action of the adjusting rod 13, driving the first push plate and the second push plate hinged thereto to rotate, and further driving the first clamping plate and the second clamping plate to move, so that the distance between the chucks 1231 of the first clamping plate and the chucks 1231 of the second clamping plate is shortened, thereby increasing the clamping force of the chucks 1231 of the first clamping plate and the chucks 1231 of the second clamping plate on the side wall of the track 4, and realizing the braking of the gantry crane; when the gantry crane moves, the adjusting rod 13 is shortened (compared with the length of the adjusting rod 13 when the gantry crane brakes), and the pressing plate 121 descends (moves towards the direction close to the support plate 124), driving the first push plate and the second push plate hinged thereto to rotate, and further driving the ends of the first clamping plate and the second clamping plate close to the push plate 122 to move towards the direction close to the pressing plate 121, then the distance between the chucks 1231 of the first clamping plate and the chucks 1231 of the second clamping plate is increased, thereby reducing the clamping force of the chucks 1231 of the first clamping plate and the chucks 1231 of the second clamping plate on the side wall of the track 4, enabling the gantry crane to move. In addition, by arranging multiple (two or more) clamping members 1 on one support frame 11, when the gantry crane brakes, it can be clamped and fixed simultaneously from multiple positions of the track 4, which helps to realize the rapid braking of the gantry crane and improve the safety and stability; arranging multiple clamping members 1 correspondingly on one support frame 11 also helps to ensure the consistency of the sliding of multiple clamping members 1 along the track 4 and ensure the braking effect.

[0042] Preferably, the adjusting rod 13 is a hydraulic rod; during specific installation, one end of the hydraulic rod can be fixedly installed above the pressing plate 121, and the telescopic rod of the hydraulic rod penetrates through the pressing plate 121 and is fixedly connected to the support plate 124. More preferably, the push rod is an electro-hydraulic rod to facilitate the electric control of the clamping of the track 4 by the clamping member 1.

[0043] As Figure 6As shown, in the preferred embodiment of the present utility model, an anti-slip plate 1234 is provided at one end of the chuck 1231 close to the track 4, and a protective plate 1232 is further provided between the anti-slip plate 1234 and the chuck 1231. Among them, the setting of the protective plate 1232 helps to protect the chuck 1231 and also facilitates the installation and fixation of the anti-slip plate 1234; the setting of the anti-slip plate 1234 helps to improve the stability during braking. Specifically, the protective plate 1232 can be detachably connected to the chuck 1231 (for example, the connection between the protective plate 1232 and the chuck 1231 is achieved through the fixing bolt 1235).

[0044] Preferably, the anti-slip plate 1234 and the protective plate 1232 are connected to the chuck 1231 through the fixing bolt 1235.

[0045] In the preferred embodiment of the present utility model, the gantry crane rail clamp has a controller and an alarm (not shown in the figure); a wear sensor 1233 is further provided on the protective plate 1232. The wear sensor 1233 is provided on one side of the protective plate 1232 close to the anti-slip plate 1234. The wear sensor 1233 and the alarm are signal-connected to the controller. The wear sensor 1233 is used to detect the wear degree of the anti-slip plate 1234, and the alarm is used to give an alarm when the signal detected by the wear sensor 1233 reaches the threshold. Specifically, the wear sensor 1233 can be provided in the middle of the protective plate 1232; the gantry crane rail clamp of the present utility model also has a controller and an alarm. The wear sensor 1233 and the alarm are respectively signal-connected to the controller (for example, through a signal line connection or through a wireless signal connection) to give an alarm when the wear degree of the anti-slip plate 1234 is relatively large (the signal detected by the wear sensor 1233 reaches the set threshold), reminding the staff to replace the anti-slip plate 1234. Among them, the controller or other electrical components in the present utility model can be electrically connected to the 220V mains according to actual needs, and the controller can be a conventional known device such as a computer that can play a control role. Electrical components (such as the wear sensor 1233, the electro-hydraulic rod 211, etc.) are selected from the corresponding products in the prior art according to actual needs. In addition, the controller can also be signal-connected to the controller for controlling the movement of the gantry crane.

[0046] As Figure 1 and 7As shown in Fig. -8, in the preferred embodiment of the present utility model, the support frame 11 includes a support plate 111 and a track wheel 112. A limit block 113 is provided on the support plate 111. The limit block 113 is snap-connected to the support plate 124 (the corresponding structure in the prior art can be adopted according to actual needs, which will not be elaborated here) and is used to limit the support plate 124 (for example, at least limit the movement of the support plate 124 in the up and down directions; that is, when the adjusting rod 13 expands and contracts, the support plate 124 cannot move in the direction close to the pressing plate 121 or close to the support plate 111); the track wheel 112 is arranged above the track 4 and is adapted to the track 4 (for example, the upper surface of the track 4 has a groove adapted to the track wheel 112). Among them, the setting of the track wheel 112 enables the support frame 11 to slide along the track 4 when the gantry crane is running, without affecting the movement of the gantry crane.

[0047] Preferably, mounting holes 1235 are respectively provided at one ends of the first clamping plate 123 and the second clamping plate 123 away from the pressing plate 121. The axes of the mounting holes 1235 are parallel to the support plate 124. A matching connecting rod 231 is arranged in the mounting holes 1235. The connecting rod 231 is connected to the support plate 124, thereby realizing the connection between the first clamping plate 123 and the second clamping plate 123 and the support plate 124.

[0048] In the preferred embodiment of the present utility model, a plurality of limit blocks 113 are provided on the support plate 111. The distance between adjacent two limit blocks 113 is adapted to the size of the support plate 124 (the above setting enables each support plate 111 to correspondingly set a plurality of linkage parts 12 and adjusting rods 13. Thus, when the gantry crane brakes, the clamping member 1 can perform multi-point clamping on the side wall of the track 4, thereby directly generating a large frictional force, ensuring the quick braking of the gantry crane, guaranteeing the stability of the gantry crane during braking, and improving the clamping effect on the track 4); a protective shell 114 is also provided on the support frame 11. Among them, the setting of the protective shell 114 helps to protect the outside of the clamping member 1.

[0049] In the preferred embodiment of the present utility model, the gantry crane rail clamp further includes a limit frame 2. The limit frame 2 is slidably assembled with the track 4. The limit frame 2 is connected to the clamping member 1; an adjustment hole 21 is provided on the limit frame 2. A pressure rod 211 is assembled at the adjustment hole 21. The axis of the pressure rod 211 is perpendicular to the side wall of the track 4. The pressure rod 211 is configured to be able to abut against the side wall of the track 4. Among them, the above setting of the limit frame 2 enables that when the gantry crane is not in use, by adjusting the pressure rod 211, the pressure rod 211 can be abutted against the side wall of the track 4, so that the limit frame 2 is fully clamped and fixed on the surface of the rail, thus helping to ensure the stability of the gantry crane; before the gantry crane moves, the pressure rod 211 is adjusted to increase the distance between the pressure rod 211 and the side wall of the track 4 or remove the pressure rod 211 from the adjustment hole 21. The limit frame 2 will not pose an obstacle to the movement of the gantry crane, and the limit frame 2 can move along with the movement of the gantry crane.

[0050] Preferably, the pressure bar 211 is threadedly connected to the adjustment hole 21.

[0051] Preferably, rollers 24 are provided on the inner side of the upper wall of the limit frame 2. The rollers 24 are adapted to the track 4 and are arranged above the track 4. Among them, the arrangement of the rollers 24 enables the limit frame 2 to smoothly move along the track 4 under the action of the rollers 24 when the gantry crane moves, reducing or avoiding the influence of the limit frame 2 on the normal movement of the gantry crane.

[0052] In a preferred embodiment of the present utility model, a guiding hole 22 is further provided on the limit frame 2. A limit cylinder 221 is slidably assembled at the guiding hole 22. Internal threads are provided inside the limit cylinder 221. The limit cylinder 221 is threadedly connected to a threaded rod 222. One end of the threaded rod 222 away from the limit cylinder 221 is connected to the output shaft of the motor 223. The limit cylinder 221 is arranged above the track 4 and is configured to be able to abut against the track 4. The above arrangement enables the threaded rod 222 to rotate when the motor 223 rotates, and then the limit cylinder 221 will move up and down under the action of the threaded rod 222; when it is necessary to brake the gantry crane, the motor 223 can be rotated to make the limit cylinder 221 move downward to abut against the track 4 (the upper wall of the track 4), so as to achieve the effect of auxiliary braking; when the gantry crane moves, the motor 223 can be reversed to raise the limit cylinder 221 upward, and then the limit frame 2 and the track 4 can no longer interact with each other, and the movement of the gantry crane will not be affected.

[0053] Preferably, the motor 223 is signal-connected to the controller to facilitate the control of the motor 223, and further facilitate the auxiliary braking of the gantry crane by adjusting the abutting force of the limit cylinder 221 against the track 4 (the limit cylinder 221 abuts against the track 4).

[0054] In a preferred embodiment of the present utility model, a cover plate 23 is further provided on the limit frame 2. The motor 223 is arranged on the cover plate 23, and the output shaft of the motor 223 penetrates through the cover plate 23; a connecting rod 231 and a connecting block 232 are further provided on the cover plate 23. One end of the connecting rod 231 is connected to the cover plate 23, and the other end is connected to the connecting block 232. The end of the connecting block 232 away from the connecting rod 231 is connected to the support portion.

[0055] Preferably, a threaded hole is provided on the end face of the support plate 111 close to the limit frame 2. The connecting block 232 has external threads, and the connecting block 232 is threadedly connected to the support plate 111.

[0056] In a preferred embodiment of the present utility model, the gantry crane rail clamp further includes a connecting frame 3. The gantry crane rail clamp further includes a connecting frame 3. The two ends of the connecting frame 3 are respectively slidably assembled with the track 4 through a base 31 (the base 31 has wheels adapted to the track 4); one end of the clamping member 1 away from the limit frame 2 is connected to the base 31; the connecting frame 3 and / or the base 31 is connected to the gantry crane. The above arrangement enables the gantry crane to drive the limit frame 2 to pull obliquely upward during the braking process of the gantry crane (for example, when the gantry crane is connected to the connecting frame 3), and further enables the gantry frame to be fully tightened by means of the limit between the limit frame 2 and the track 4, reducing the occurrence of the gantry crane tipping over.

[0057] Preferably, a protective shell 114 is further provided on the clamping member 1. A flange 1141 is provided at one end of the protective shell 114 close to the base 31, and the base 31 is connected to the flange 1141.

[0058] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes.
