Description
Technical Field
[0001] The utility model belongs to the technical field of crane spreader adjusting equipment, and particularly relates to a special tool for adjusting the position of a spreader lock head. Background Art
[0002] As an important tool for gantry cranes and rubber-tyred gantry cranes, spreaders are used very frequently in the daily work of port container terminals, and the daily opening and closing action frequency can reach more than 800 times.
[0003] At present, the common spreader opening and closing mechanism mainly consists of components such as a lock head, a lock sleeve, a pull rod (oil cylinder), a swing arm, a ball bowl, and detection limits. Among them, the lock head and the lock sleeve are used in cooperation and are fixed on the spreader main beam; and considering that the spreader will be subjected to a certain impact when contacting the container, a reasonable gap is generally provided between the lock head and the spreader main beam. Therefore, if the lock head is not accurately positioned during installation, under the long-term high-frequency operation of the spreader, the gap between the various components in the spreader opening and closing mechanism is likely to gradually increase due to long-term wear, resulting in the situation that the lock head does not return to the proper position in the unlocked state, and further leading to the problem that the lock head is likely to scrape the container lock hole when the spreader hooks, and even causing the container to fall.
[0004] Based on this, during the installation and maintenance of the spreader opening and closing mechanism, it is necessary to design a tool that can accurately position the lock head when the lock head is replaced, so as to ensure the accuracy of the relative position between the lock head and the spreader, eliminate the hidden danger of the spreader lock head scraping the container during operation, and ensure safe production. Summary of the Utility Model
[0005] The technical problem solved by the utility model is to provide a special tool for adjusting the position of a spreader lock head, and enable it to accurately position the lock head when the lock head is replaced, so as to ensure the accuracy of the relative position between the lock head and the spreader, eliminate the hidden danger of the spreader lock head scraping the container during operation, and ensure safe production.
[0006] To solve the above technical problem, the technical solution provided by the utility model is: a special tool for adjusting the position of a spreader lock head, which includes two adjusting rods arranged in parallel. One end of the two adjusting rods is jointly provided with a first positioning block, and the other end of the two adjusting rods is provided with a second positioning block. In this way, when using the utility model for lock head replacement operation, the operator can first clamp the first positioning block and the second positioning block of the utility model on the lower end of the spreader main beam, and then constrain the position of the lock head in the horizontal direction perpendicular to the length direction of the adjusting rods through the two adjusting rods, so as to realize the accurate positioning of the lock head position on the spreader, eliminate the hidden danger of the spreader lock head scraping the container during operation, and ensure safe production.
[0007] Further, the first positioning block includes a first connecting block which is fixedly installed on two adjusting rods. At least one L-shaped first positioning plate is provided at the upper end of the first connecting block, and the fold angle of the first positioning plate faces the second positioning block.
[0008] Further, the first positioning block includes two first connecting blocks which are respectively fixedly installed on two adjusting rods. One L-shaped first positioning plate is provided at the upper end of each of the two first connecting blocks. A first connecting rod is connected between the two first connecting blocks and / or between the two first positioning plates, and the connection mode of the first connecting rod is preferably welding.
[0009] Further, the second positioning block includes a second connecting block which is installed on two adjusting rods. At least one L-shaped second positioning plate is provided at the upper end of the second connecting block. The second positioning plate is arranged opposite to the first positioning plate, and the whole tool is fixed to the lower end of the main beam of the spreader through the cooperation between the first positioning plate and the second positioning plate.
[0010] Further, the second positioning block includes two second connecting blocks which are respectively installed on two adjusting rods. One L-shaped second positioning plate is provided at the upper end of each of the two second connecting blocks. The second positioning plate is arranged opposite to the first positioning plate.
[0011] Further, a second connecting rod is connected between the two second connecting blocks and / or between the two second positioning plates, and the connection mode of the second connecting rod is also preferably welding.
[0012] Further, the second connecting block is slidably sleeved on the corresponding adjusting rod. The end of the adjusting rod far from the first connecting block passes through the second connecting block and is threadedly connected with a fixing nut. The second connecting block can be driven to approach the first connecting block by screwing the fixing nut, and the position of the second connecting block can be restricted, so as to ensure that the whole tool of the present utility model can be fixed to the lower end of the main beam of the spreader through the cooperation between the first positioning plate and the second positioning plate. At the same time, since the second positioning block in the present utility model adopts a movable structure, it can also be applicable to spreader main beams of various sizes.
[0013] Further, a washer is arranged between the second connecting block and the fixing nut.
[0014] From the above technical solutions, it can be seen that the present utility model has the following advantages: When using the present utility model for the operation of replacing the lock head, the operator can first clamp the first positioning block and the second positioning block of the present utility model to the lower end of the main beam of the spreader, and then restrict the position of the lock head in the horizontal direction perpendicular to the length direction of the adjusting rod through the two adjusting rods, so as to realize the accurate positioning of the lock head position on the spreader, eliminate the hidden danger of the spreader lock head scratching the container during the operation, and ensure the safety production.
