Description

Technical Field

[0001] This application relates to the field of mobile limit vehicle technology, and in particular to a track end limiter for a mobile ship unloader. Background Technology

[0002] As a device that uses continuous conveying machinery to lift bulk materials, the fixed triggering mechanism for the front and rear stop limits of the ship unloader is only located on the southernmost and northernmost sides of the trolley track. During the unloading operation, as the unloading operation continues and the ship gradually floats, the distance between the front beam of the ship unloader, the driver's cab, and the ship's bridge continuously decreases, and the risk of collision increases accordingly.

[0003] The water-based area is divided into an unloading operation area and a ship living area. If a side triggering mechanism is not installed in the land-based area, the unloader's receiving plate and operator's cab are very likely to collide with the ship living area during operation. In addition, the unloader has two installation areas for limit switches. The installation height of the limit switches and the distance between the limit switches and the trolley rails are different in the two installation areas, but both distances are fixed values. To ensure that the limit function works properly, the triggering height of the limit structure needs to be adjusted frequently and in a timely manner. Due to the variable berthing position of ships, the safe operating area of ​​the unloader also changes. Operators need to flexibly move the side triggering mechanism according to the actual working conditions to limit the operating range of the unloader. However, the triggering iron block in the limit structure is heavy, making its movement difficult, which not only consumes manpower but may also affect the work efficiency and safety protection effect. Summary of the Invention

[0004] This device provides a movable ship unloader trolley track end limiter, the specific implementation of which is as follows:

[0005] A movable ship unloader trolley track end limiter includes:

[0006] The base has a traveling part with a self-locking structure.

[0007] The first and second limiting plates are respectively set at different height positions of the seat body. The seat body is arranged on the side of the trolley track. The limiting plates are used to abut against the limit switches on the trolley of the contact unloader, thereby limiting the sliding range of the trolley along the trolley track.

[0008] The second limiting plate is horizontally slidably connected to the base body through a telescopic assembly, and a pin is provided at the sliding point to lock the sliding length. The first and second limiting plates trigger the limit switches located at different installation heights in the trolley of the ship unloader.

[0009] The traveling part includes several fixed seats located at the bottom corners of the seat body. Wheels are rotatably mounted on the outside of the fixed seats, and a raised seat is threaded to the bottom of the fixed seats. The raised seat is used to suspend the wheels after the seat body moves into place, so as to improve the stability of the seat body during the limited movement.

[0010] Based on the above technical solutions, by setting up a mobile limiting vehicle with a walking mechanism, both the flexibility of handling is achieved, and the raised seat ensures overall stability after the vehicle is moved into place. Furthermore, by vertically setting the second limiting plate and the first limiting plate in sequence, the height-related limiting adaptability of the unloader trolley is improved. At the same time, the second limiting plate is made to be translatable by a telescopic component, so that the second limiting plate can always meet the limiting triggering effect of the limit switch at the low position according to the different fixed positions of the seat body. That is, when the distance between the seat body and the limit switch is uncertain during low limit detection, the second limiting plate can be adjusted according to the actual fixed position of the seat body.

[0011] Preferably, the second limiting plate is fixedly connected to the top of the seat, the second limiting plate and the first limiting plate are offset from each other, the side contours of the two are in the same vertical plane, and there is no gap between the upper and lower edges of the two.

[0012] Based on the above technical solution, by eliminating the gap between the upper and lower edges of the second limiting plate and the first limiting plate in the right view, the two plates laterally cover the range of the limit switches that are triggered at different installation heights, thereby increasing the triggering height range.

[0013] Preferably, the telescopic component includes a positioning cylinder, with a sliding rod slidably disposed inside the positioning cylinder; a pin is disposed on the outside of the positioning cylinder, and the sliding rod has a plurality of positioning holes equidistantly opened along its axial direction, the end of the pin being threadedly inserted into the positioning cylinder through a connector, and the connector being inserted into any positioning hole.

[0014] Preferably, the first limiting plate and the second limiting plate have the same structure. Taking the second limiting plate as an example, its two ends are set as guide slopes that act on the limit switches on the ship unloader trolley.

[0015] Based on the above technical solutions, by setting a positioning hole on the sliding rod with a pin, the sliding distance of the sliding rod and the second limiting plate relative to the seat is locked; and the guide slope is set to achieve a smooth transition between the limiting plate and the trigger end of the limit switch.

[0016] Preferably, the positioning cylinder is a square tube structure, and the sliding rod is a hollow column structure; the top of the sliding rod is provided with an axial waist-shaped guide groove, the positioning hole is located at the bottom of the sliding rod, and the waist-shaped guide groove radially covers each positioning hole.

[0017] Based on the above technical solutions, the top of the sliding rod is provided with an axially shaped guide groove, and the positioning hole is located at the bottom of the sliding rod. This allows the pin to not only lock the position of the sliding rod after it slides, but also enhances the stability of the sliding rod during the sliding process. The pin can be a manually locked threaded bolt structure, a press-type pin structure, or a motor-driven structure. The telescopic component can be a single unit, namely a single sliding rod and a single positioning cylinder. The pin and the axially shaped guide groove on the top of the sliding rod can also maintain the horizontality of the second limiting plate during the pull-out process.

[0018] Preferably, a pair of telescopic components can be arranged side by side, and the outer end face of each sliding rod is connected to the back of the second limiting plate. The inner end face of the sliding rod is connected to a spacing adjustment rod. The two spacing adjustment rods work together to abut against the trolley track to calibrate the parallelism between the seat and the trolley track.

[0019] Based on the above technical solution, by setting a pair of spacing adjustment rods, the parallelism between the seat and the trolley track can be aligned through two-point positioning. After the parallelism adjustment is completed, the spacing adjustment rods are retracted to avoid the trolley track. On this basis, the seat is fixed and the limiting plate is extended. The seat and the trolley track are aligned to be parallel, which can provide a more accurate limiting effect.

[0020] Preferably, the spacing adjustment rod and the sliding rod are in the form of a C-shape. The spacing adjustment rod includes a connecting rod and a telescopic rod that are joined at an angle. The end of the telescopic rod is hinged with an abutment for engaging the main carriage rail.

[0021] Based on the above technical solution, by hinged at the end of the telescopic rod and equipped with a conventional locking key at the hinge, the abutment is triangular in shape and is locked from the inside of the trolley track, thereby improving the stability of the alignment.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. This utility model improves the height-related limit adaptability of the ship unloader trolley by vertically setting a second limiting plate and a first limiting plate in sequence. At the same time, the second limiting plate is made into a movable state by means of a telescopic component. When the fixed position of the seat is different, the movable second limiting plate can arbitrarily adjust the distance between it and the limit switch at the lower position, so that it can always be effectively triggered.

[0024] 2. By setting a fixed seat, a raised seat, and wheels, the mobility of this limiting vehicle is satisfied, and the stability of the whole after it is moved into place is also achieved with the help of the raised seat.

[0025] 3. In this utility model, the top of the sliding rod is provided with an axially shaped guide groove, and the positioning hole is provided at the bottom of the sliding rod, so that the pin can not only lock the position of the sliding rod after sliding, but also enhance the stability of the sliding rod during the sliding process;

[0026] 4. This utility model has a simple structure. By setting a pair of spacing adjustment rods, the parallelism between the seat and the trolley track can be first aligned by two-point positioning, making the subsequent limit adjustment more accurate. Attached Figure Description

[0052] The walking part 2 includes several fixed seats 201 located at the bottom corners of the seat body 1. The fixed seats 201 are rotatably sleeved with wheels 203, and the bottom end of the fixed seats 201 is threaded with a raised seat 202. The raised seat 202 is used to suspend the wheels 203 after the seat body 1 moves into place, so as to improve the stability of the seat body 1 during the limited movement.
