Description

Technical Field

[0001] The utility model relates to the technical field of vehicle bogies, and more particularly to a limiter and a bogie on which the limiter is installed. Background Art

[0002] Rail vehicle bogies are a key component of railway vehicles. Their primary function is to support the vehicle body, guide the vehicle smoothly along the rails, and transfer the vehicle's weight and various forces (such as traction and braking) to the track, ensuring the safe and smooth operation of the train. Bogies primarily consist of a frame, wheels, suspension system, and braking devices.

[0003] At present, when the rail vehicle bogie is stationary on a supporting surface such as the ground, it is not placed stably enough. The wheels of the bogie are prone to rolling and moving with the bogie, causing collision damage and posing a safety threat to the workers. Some sites will look for wood, bricks, etc. to jam the wheels. This method is time-consuming and labor-intensive, and has a poor limiting effect on the bogie, and cannot be recycled.

[0004] Therefore, it is necessary to provide a limiter and a bogie equipped with the limiter to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a limiter and a bogie equipped with the limiter to solve the above technical problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A limiter, comprising:

[0008] A mounting rod, wherein a limiting mechanism is provided on the mounting rod;

[0009] The limiting mechanism includes a movable seat connected to the mounting rod, a mounting plate movably connected to the movable seat, and a limiting block is installed on one side of the mounting plate;

[0010] The adjusting component is arranged on the movable seat and is used for driving the mounting plate to move.

[0011] Furthermore, the adjusting component includes:

[0012] A screw rod is threadedly connected to the movable base, and one side of the mounting plate is connected to the screw rod;

[0013] A sliding rod is connected to the mounting plate and movably passes through the movable seat.

[0014] Furthermore, a socket is provided on the mounting plate, an insert block adapted to the socket is provided on the limit block, a limiting hole is provided on the insert block, and a limiting component adapted to the limiting hole is provided on the mounting plate.

[0015] Furthermore, a slide groove is provided in the mounting plate, and the limiting component includes:

[0016] an elastic member, arranged at the upper end of the mounting plate, wherein the upper end of the elastic member is provided with a pull plate;

[0017] A shift rod has one end connected to the pull plate and the other end slidingly extends into the slide groove and is connected to a limiting block.

[0018] A bogie comprises the above-mentioned limiter, wherein the limiter is detachably mounted on a rotating shaft of the bogie.

[0019] Furthermore, a plurality of positioning holes are provided at both ends of the rotating shaft;

[0020] A mounting block is provided at one end of the mounting rod, and a mounting hole matching the positioning hole is opened on the mounting block.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This solution installs the limiter of this application on the bogie, and then drives the limit block to move and contact the wheel by operating the adjustment component. The limit blocks on multiple limit mechanisms can limit each wheel of the bogie. At this time, the bogie can be placed stably, avoiding the current phenomenon that the bogie is not stable enough on the ground and the wheels of the bogie are prone to rolling, thereby greatly preventing the bogie from moving and causing collision damage and danger to the staff. The limiting effect of the bogie is good, and there is no need to find ways to clamp the wheels with wood, bricks, etc., and the limiter can be used cyclically. When the bogie does not need the limiter, it can be removed from the bogie and wait for the next use or used on other bogies. It has a wide range of applications, higher practicality, and can be widely promoted and used.

[0023] 2. This solution can fix the limit block on the mounting plate through the limiting component, and can also operate the limiting component to separate the limit block from the mounting plate, so that the limit block can be installed and removed conveniently and quickly, and then limit blocks of different specifications can be replaced according to the wheel specifications of different bogies. It has strong flexibility and a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] When in use, first install the stopper on the bogie 2 to Figure 1The cam 33 is moved to the left of the wheel 2 and the cam 33 is moved to the right of the wheel 2. The cam 33 is moved to the right of the wheel 2 and the cam 33 is moved to the left of the wheel 2. The cam 33 is moved to the right of the wheel 2 and the cam 33 is moved to the right of the wheel 2.

[0036] In this embodiment, preferably, please refer to Figure 2-4 The adjustment component 34 includes a screw rod 341, which is threadedly connected to the movable base 31 and connected to one side of the mounting plate 32; and a slide rod 342, which is connected to the mounting plate 32 and movably extends through the movable base 31. By rotating the screw rod 341, the screw rod 341 also moves. At the same time, with the cooperation of the slide rod 342, the mounting plate 32 moves along with the screw rod 341, driving the slide rod 342 to move together. At this time, the mounting plate 32 also drives the limit block 33 to move together.

[0037] In this embodiment, preferably, please refer to Figure 2-5 The mounting plate 32 is provided with a socket 9, the limit block 33 is provided with an insert block 10 adapted to the socket 9, the insert block 10 is provided with a limiting hole 11, and the mounting plate 32 is provided with a limiting component 12 adapted to the limiting hole 11.

[0038] When the limit block 33 is installed, the plug block 10 of the limit block 33 is inserted into the socket 9 of the mounting plate 32. When the plug block 10 is moved to the specified position, the plug block 10 can be fixed and restricted by the cooperation of the limiting component 12 and the limiting hole 11. At this time, the limit block 33 can be fixed on the mounting plate 32, and the installation of the limit block 33 is completed. When dismantling is subsequently performed, the limiting component 12 can be operated to release the restriction on the plug block 10, and the plug block 10 can be pulled out of the socket 9, thereby separating the limit block 33 from the mounting plate 32, and the dismantling of the limit block 33 is completed, so that the limit block 33 can be installed and disassembled conveniently and quickly, and then different specifications of limit blocks 33 can be replaced according to the wheel specifications of different bogies 2, which can be used for different bogies 2.

[0039] In this embodiment, preferably, please refer to Figure 2-5 A slide groove 13 is provided in the mounting plate 32, and the limiting component 12 includes: an elastic member 121, which is arranged at the upper end of the mounting plate 32, and a pull plate 122 is provided at the upper end of the elastic member 121; a shift rod 123, one end of which is connected to the pull plate 122, and the other end slides and extends into the slide groove 13 and is connected to a limiting block 124. The elastic member 121 in the present application can be a spring, and the side of the limiting block 124 facing the opening of the socket 9 is an inclined surface. When the plug block 10 of the limit block 33 is inserted into the socket 9 of the mounting plate 32, the plug block 10 contacts the limiting block 124 and squeezes it. The limiting block 124 will move toward the inside of the slide groove 13 and drive the shift rod 123 to move up and stretch the elastic member 121. When the plug block 10 is inserted into the specified position, the limiting hole 11 is located at the position of the limiting block 124. The limiting block 124 is not under pressure at this time. The rebound force of the elastic member 121 will drive the shift rod 123 and the limiting block 124 to move downward, and finally the limiting block 124 will enter the limiting hole 11, thereby limiting and fixing the plug block 10, that is, completing the limiting fixation of the limit block 33. When the limit block 33 is subsequently disassembled, the pull plate 122 can be pulled upward to drive the shift rod 123 to move upward, and the limit block 124 carried by the shift rod 123 moves upward. When the limit block 124 is out of the limiting hole 11, it no longer restricts the plug block 10. At this time, the plug block 10 can be removed from the socket 9. At this time, the limit block 33 can be removed from the mounting plate 32, and the disassembly and assembly are simple and quick.
