In order to ensure the safety and efficiency of the gantry crane during operation, the stop device at the end of the track is a vital component. The main function of the stop device is to prevent the operating mechanism of the gantry crane from exceeding the designed track range and avoid accidents caused by equipment slipping out of the track. This restriction mechanism ensures that the gantry crane will not accidentally derail during movement, protecting the safety structure of the equipment and the surrounding environment.

[0003] The end stop device of the bridge gantry crane track is generally composed of a stop frame, a stop plate and a base welded together and fixed to the end of the track by bolts. When the existing bridge gantry crane track end stop device is disassembled, all the bolts need to be removed. When the bridge gantry crane is working with a light load, the bridge gantry crane track end stop device is not needed at this time, because the stop device will limit the movement range of the bridge gantry crane, resulting in the operator being unable to flexibly adjust the position of the equipment when handling light loads. At the same time, the stop device limits rapid placement and transportation, which will lead to reduced work efficiency. Utility Model Content

[0030] The positioning component 200 includes a first stop block 201 and a second stop block 202 slidingly arranged on the base 101, wheel buffer blocks 203 respectively arranged at the ends of the first stop block 201 and the second stop block 202, a guide assembly 204 arranged on the base 101, a pushing assembly 205 arranged in the first stop block 201, a fixing assembly 206 arranged in the second stop block 202, and a transmission assembly 207 arranged in the second stop block 202. The wheel buffer block 203 is in contact with the end face of the rail end, and the first stop block 201 and the second stop block 202 are fixed to the base 101 through the positioning component 200.

[0031] Furthermore, the end of the wheel buffer block 203 is curved, and the first blocking block 201 and the second blocking block 202 are adapted to the track. The curved end of the wheel buffer block 203 can effectively slow down or absorb the impact force caused by inertia of the gantry crane.

[0032] Furthermore, the guide assembly 204 includes guide grooves 204a respectively arranged on both sides of the base 101, and guide blocks 204b are respectively arranged at the bottom of the first blocking block 201 and the second blocking block 202.

The guide blocks 204b slide on the guide grooves 204a, so that the first blocking block 201 and the second blocking block 202 are adapted to the base 101 to block the bridge gantry crane.

[0033] During use, the first blocking block 201 and the second blocking block 202 are adapted to the base 101 to block the gantry crane and prevent it from exceeding the track. When the gantry crane is working with light load, the first blocking block 201 and the second blocking block 202 are quickly removed from the base 101 through the positioning component 200 to prevent the first blocking block 201 and the second blocking block 202 from limiting the movement range of the gantry crane.

[0034] Example 2

[0035] Reference Figures 1 to 5 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: the pushing assembly 205 includes a cavity 205a arranged in the first blocking block 201, a screw rod 205b is rotatably arranged in the first blocking block 201, and a pushing block 205c is slidably arranged in the cavity 205a. The pushing block 205c is connected to the screw rod 205b by a thread. When the screw rod 205b is rotated, the screw rod 205b drives the pushing block 205c to slide along the cavity 205a, so that the pushing block 205c slides outward.

[0036] Furthermore, the cavity 1 205a is rectangular, and a knob 205b-1 is provided at the end of the screw rod 205b. By rotating the knob 205b-1, the knob 205b-1 drives the screw rod 205b to rotate, and the knob 205b-1 facilitates the user to rotate the screw rod 205b.

[0037] Furthermore, two fixing components 206 are provided, and the fixing components 206 include a sliding groove 206a provided in the second blocking block 202, a positioning column 206b is slidingly provided on the sliding groove 206a, and a limiting hole 206c is provided on the base 101. The positioning column 206b and the limiting hole 206c are adapted to each other, and the second blocking block 202 is driven to be limited on the base 101 by the fixing component 206. When the positioning column 206b slides, the positioning column 206b is adapted to the limiting hole 206c, so that the second blocking block 202 is limited on the base 101.

[0038] Furthermore, a piston 206b-1 is provided at the bottom of the positioning column 206b. The piston 206b-1 is slidably provided on the sliding groove 206a. When the piston 206b-1 slides, the piston 206b-1 drives the positioning column 206b to slide synchronously.

[0039] Furthermore, a spring 206b-2 is provided on the outside of the positioning column 206b, and both ends of the spring 206b-2 are respectively connected to the corresponding surfaces of the piston 206b-1 and the sliding groove 206a, and the positioning column 206b is reset by the elasticity of the spring 206b-2.

[0040] During use, when the piston 206 b - 1 slides, the piston 206 b - 1 drives the positioning column 206 b to slide, so that the positioning column 206 b is adapted to the limiting hole 206 c, so that the second blocking block 202 is fixed on the base 101 .

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3

[0043] Reference Figures 1 to 5 , which is the third embodiment of the present utility model. This embodiment is different from the second embodiment in that: the transmission component 207 includes a second cavity 207a arranged in the second blocking block 202, a transmission plate 207b is slidably arranged on the second cavity 207a, and a sealing ring is provided on the outer side of the transmission plate 207b, which is adapted to the first blocking block 201 through the transmission component 207.

[0044] Furthermore, the pushing block 205c is adapted to the second cavity 207a, and the second cavity 207a is connected to the sliding groove 206a. When the pushing block 205c slides, the pushing block 205c squeezes the transmission plate 207b, causing the transmission plate 207b to slide along the second cavity 207a, thereby squeezing the air in the second cavity 207a into the sliding groove 206a, causing the air pressure in the sliding groove 206a to increase, and the increase in air pressure causes the piston 206b-1 to slide.

[0045] The remaining structures are the same as those of Example 2.

[0046] Working principle: The first stop block 201 and the second stop block 202 are fitted with the base 101 by adapting the guide block 204b to the guide groove 204a. When the knob 205b-1 is turned, the knob 205b-1 drives the screw rod 205b to rotate, and the screw rod 205b drives the push block 205c to slide. The push block 205c squeezes the transmission plate 207b, causing the transmission plate 207b to slide along the second cavity 207a, thereby squeezing the air in the second cavity 207a into the sliding groove 206a, causing the air pressure in the sliding groove 206a to increase. The increased air pressure causes the piston 206b-1 to The piston 206b-1 slides and drives the positioning column 206b to slide synchronously. The positioning column 206b is adapted to the limiting hole 206c, so that the second blocking block 202 is limited on the base 101, and the first blocking block 201 is liquid-limited on the base 101 through the adaptation of the pushing block 205c and the second cavity 207a. When the bridge gantry crane is working with light load, the knob 205b-1 is rotated in the opposite direction to release the first blocking block 201 and the second blocking block 202 from the base 101, thereby realizing quick disassembly. At the same time, when the first blocking block 201 or the second blocking block 202 is damaged, it can be quickly replaced.
