Description

Technical Field

[0001] The utility model belongs to the technical field of container spreader maintenance, and in particular relates to a container spreader top pin debugging tool. Background Art

[0002] In the management of container crane equipment on site, spreaders are an important component to ensure the normal operation of the equipment. In the fault management of container crane equipment on site, the opening and closing failures of spreaders account for about 38% of the total equipment failures.

[0003] At present, when the spreader fails to open or lock, it is necessary to use the lifting lock hole on the top of the container to debug the opening and locking of the spreader. During the maintenance process, the maintenance personnel need to use a ladder to perform high-altitude operations, that is, the maintenance personnel need to climb to the top of the ladder and fasten the safety belt to handle and debug; and during the entire maintenance process, the maintenance personnel also need to use manual force to handle and debug the limit pin or lock accessories, that is, they need to forcibly lift the limit pin with their hands and then pad a nut at the limit pin mouth.

[0004] Therefore, when maintenance personnel debug and handle the opening and locking faults of the hoist, the following problems exist: 1. When operating alone, it is easy to have problems with the stability of the escalator because it requires both hands to operate vigorously, which leads to great safety hazards in the entire debugging process; 2. When operating with two people, there is a problem of limited space, which makes it inconvenient for two maintenance personnel to perform corresponding operations. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a container spreader top pin debugging tool with high safety factor and convenient operation, so as to facilitate maintenance personnel to debug and handle the opening and closing faults of the spreader and improve maintenance efficiency.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a container spreader top pin debugging tool, which includes an auxiliary plate and an inverted U-shaped fixed frame, the fixed frame includes a crossbeam, and a column is provided at each end of the crossbeam; one end of the auxiliary plate is hinged to one of the columns of the fixed frame, and the other end of the auxiliary plate is detachably connected to the other column of the fixed frame, and the middle part of the auxiliary plate is threadedly connected to a top pin bolt, and the upper end of the top pin bolt passes through the auxiliary plate and is arranged toward the crossbeam. In this way, when using the present invention to debug the sling, the auxiliary plate and the fixed frame can be opened first, and then the fixed frame can be placed across the sling frame, and the position of the top pin bolt can be made to correspond to the position of the top pin on the sling; then the other end of the auxiliary plate can be connected to another column of the fixed frame, that is, the auxiliary plate and the fixed frame can be closed; finally, the maintenance personnel can screw the top pin bolt, and as the top pin bolt is screwed, the top pin bolt will continue to rise until the top pin bolt lifts the top pin; at this time, as the top pin is lifted, the sling will be in a boxed state, and the mechanical lock of the sling will be in an open state, so that the sling can be smoothly switched between unlocking and locking states. Based on this, since the maintenance personnel only need to screw the top pin bolt to realize the lifting action of the top pin during the entire process, it can not only be operated by one person, reducing the difficulty of maintenance and improving maintenance efficiency; there is also no problem of needing to operate with both hands vigorously, thereby greatly improving the safety of the maintenance personnel.

[0007] Furthermore, a fixing threaded piece is fixedly installed in the middle of the auxiliary plate, the fixing threaded piece is threadedly connected to the top pin bolt, and the stability of the top pin bolt is ensured by a sufficiently long threaded connection section between the top pin bolt and the fixing threaded piece.

[0008] Furthermore, a positioning sleeve is fixedly installed on the middle part of the auxiliary plate facing the crossbeam. The positioning sleeve is sleeved on the outside of the push pin bolt and can be sleeved on the outside of the push pin during use to radially position and radially constrain the push pin to prevent radial movement of the push pin bolt.

[0009] Furthermore, an observation hole is provided on the side wall of the positioning sleeve, and the observation hole facilitates maintenance personnel to observe the relative position between the ejector bolt and the ejector pin during the process of screwing the ejector bolt.

[0010] Furthermore, a sleeve 1 is provided at the lower end of one of the columns of the fixed frame, at least one sleeve 2 is provided at one end of the auxiliary plate, one end of the pin is provided with an abutment portion, and the other end of the pin alternately passes through sleeve 1 and sleeve 2 and then is plugged into a latch. In this way, the present invention can hinge one of the columns of the fixed frame and the corresponding end of the auxiliary plate together through the cooperation of the pin and sleeve 1 and sleeve 2, allowing the two to rotate relative to each other.

[0011] Furthermore, a connecting hole 1 is provided at the lower end of one of the columns of the fixed frame, and a connecting hole 2 is provided at one end of the auxiliary plate. One end of the connecting bolt passes through the connecting hole 2 and is threadedly connected to the connecting hole 1, thereby detachably connecting one of the columns of the fixed frame and the corresponding end of the auxiliary plate.

[0012] It can be seen from the above technical solution that the utility model has the following advantages: when using the utility model to debug the sling, the maintenance personnel only need to screw the push pin bolt to realize the lifting action of the push pin, which not only can realize single-person operation, reduce the difficulty of maintenance and improve maintenance efficiency; there is also no problem of requiring both hands to operate vigorously, thereby greatly improving the safety of maintenance personnel.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1 As shown, the utility model provides a container spreader top pin debugging tool, which includes an auxiliary plate 2 and an inverted U-shaped fixed frame 1. The fixed frame 1 includes a crossbeam, each end of which is provided with a column, and the lower end of one of the columns of the fixed frame 1 is provided with a sleeve 1, and the lower end of the other column of the fixed frame 1 is provided with a connecting hole 1.

[0018] One end of the auxiliary plate 2 is provided with at least one sleeve 2, and is hingedly connected to the column of the fixed frame 1 equipped with the sleeve 1 via a pin 3. Specifically, one end of the pin 3 is provided with an abutment portion, and the other end of the pin 3 alternately passes through sleeves 1 and 2 and is then connected with a latch, thereby achieving a hinged connection between one of the columns of the fixed frame 1 and the corresponding end of the auxiliary plate 2, allowing the two to rotate relative to each other.

[0019] The other end of the auxiliary plate 2 is provided with a second connecting hole, and one end of the connecting bolt is passed through the second connecting hole and threadedly connected to the first connecting hole, thereby detachably connecting one of the columns of the fixed frame 1 to the corresponding end of the auxiliary plate 2.
