[0002] A gantry crane is a deformation of a bridge crane. Its metal structure is like a portal frame. Two 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, strong versatility, etc., and is widely used in port freight yards; the crane stopping device is an important safety protection device. Its function is that when the trolley and the crane run beyond the limit position and reach the track terminal, the stopping device can ensure the safe docking of the crane. The stopping device plays a great role in ensuring the safe operation of the gantry crane and preventing the occurrence of equipment and personal injury accidents.

[0021] Referring to Figures 1-4 , the present utility model provides a gantry crane parking block assembly device, including an assembly mechanism 1. A buffer device 2 is fixedly connected to the top of the assembly mechanism 1, and a travel track 3 is fixedly connected to the bottom of the assembly mechanism 1. The assembly mechanism 1 includes a fixed base 101. A connection groove 102 is opened in the middle of the bottom of the fixed base 101. Connection plates 103 are fixedly connected to the bottoms of the front and back of the fixed base 101. A connection column 104 is movably connected to the front of the connection plate 103. Fixed nuts 105 are movably connected to the outer sides of the front and back of the connection column 104. Threaded rods 106 are fixedly connected to the four corners of the top of the fixed base 101. Installation nuts 107 are movably connected to the outer sides of the threaded rods 106. By matching the connection groove 102 of the fixed base 101 with the travel track 3, the fixed base 101 is installed on the travel track 3. By mutually matching the thread of the connection column 104 with the fixed nut 105, the fixed base 101 and the travel track 3 are fixed, which is beneficial to facilitate the installation and disassembly of the parking block, making the parking block easy to move and facilitating the reuse of the parking block, reducing costs.
[0022] In a preferred implementation manner, threads are provided on the outer sides of the front and back of the connection column 104, and the outer thread of the connection column 104 is mutually adapted to the fixed nut 105.
[0023] In a preferred implementation manner, the buffer device 2 includes a hydraulic cylinder 201. An inner cylinder 202 is fixedly sleeved on one side inside the hydraulic cylinder 201. A buffer spring 203 is fixedly connected to one side inside the inner cylinder 202. Hydraulic oil is provided inside the inner cylinder 202.
[0024] In a preferred embodiment, a piston 204 is fixedly connected to the other side of the buffer spring 203. The outer side of the piston 204 is movably sleeved with the inner side of the inner cylinder 202. A piston rod 205 is fixedly sleeved inside the piston 204. A baffle 206 is fixedly connected to the other side of the piston rod 205. When the crane moves towards the parking stopper and impacts on the baffle 206, the piston rod 205 moves into the hydraulic cylinder 201. The piston 204 moves and compresses the buffer spring 203. At the same time, the hydraulic oil pressure rises, generating a great resistance, causing the crane to stop moving, which is beneficial to safely stop the crane and prevent the crane from colliding and damaging the equipment.
[0025] In a preferred embodiment, a cylinder head 207 is fixedly connected to the other side of the hydraulic cylinder 201. The middle parts on both sides of the cylinder head 207 are movably sleeved with the piston rod 205. A mounting plate 208 is fixedly connected to the bottom of the hydraulic cylinder 201.
[0026] In a preferred embodiment, the traveling track 3 includes a track body 301. Fixed members 302 are fixedly connected to the bottoms of the front and back surfaces of the track body 301. Connecting holes 303 are formed in the middle positions near one side of the front and back surfaces of the track body 301. The middle parts of the connecting holes 303 are mutually adapted to the middle part of the connecting column 104.
[0027] The working principle of the present utility model: When in use, the traveling track 3 is laid at the working site. The fixed members 302 and the track body 301 are fixed to the ground by the cooperation of bolts and nuts. The fixed base 101 is installed on the traveling track 3 through the cooperation of the connecting groove 102 of the fixed base 101 and the traveling track 3. The fixed base 101, the connecting plate 103 and the traveling track 3 are fixed through the cooperation of the thread of the connecting column 104 and the fixing nut 105 and the mutual adaptation of the middle part of the connecting hole 303 and the connecting column 104, which is beneficial to conveniently install and disassemble the parking stopper, making the parking stopper easy to move and facilitating the reuse of the parking stopper, reducing costs. The mounting plate 208 is fixed to the top of the fixed base 101 through the cooperation of the threaded rod 106 and the mounting nut 107. Then, the buffer device 2 is installed on the top of the fixed base 101. When the crane moves towards the parking stopper and impacts on the baffle 206, the piston rod 205 moves into the hydraulic cylinder 201. The piston 204 moves and compresses the buffer spring 203. At the same time, the hydraulic oil moves towards the other side through the gap between the piston 204 and the inner cylinder 202. The space on one side of the inner cylinder 202 decreases, and the liquid pressure rises, generating a great resistance, causing the crane to stop moving, which is beneficial to safely stop the crane and prevent the crane from colliding and damaging the equipment.
[0028] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
