Description

Technical Field

[0001] This utility model relates to the field of track inspection instrument technology, and in particular to an anti-slip device for track inspection instruments. Background Technology

[0002] Track inspection instruments are essential equipment for detecting the geometric parameters of railway tracks and are widely used in routine railway maintenance and repair work. Operators typically push these instruments along the tracks to collect data. These track-pushing instruments generally have a push rod attached, requiring manual pushing to move them forward; starting and stopping are entirely manual control. No measures are considered to prevent the instrument from slipping off the track when stopped. Therefore, manual control is necessary once the track inspection instrument is placed on the track. However, in actual field use, due to operator negligence, especially on slopes or in windy conditions, track inspection instruments frequently slip off, causing damage and even affecting train operation, posing serious safety hazards.

[0003] Currently, none of these testing instruments are equipped with anti-slip devices. According to patent literature, patent application CN219257342U describes a parking device for a track inspection instrument. This device uses a handle to brake when the track inspection instrument stops testing, which is a passive braking method. If the operator forgets to brake after stopping testing, the instrument can easily slip. Furthermore, this braking method requires the operator to bend down to operate, which is extremely inconvenient. Therefore, improvements are needed. Utility Model Content

[0004] Therefore, it is necessary to provide a track inspection instrument anti-slip device to address the above problems.

[0005] A track inspection instrument anti-slip device includes a frame, a push rod, a traveling wheel, and a brake assembly. The frame is movably placed on the track via the traveling wheel. The lower end of the push rod is connected to the frame, and the upper end of the push rod is provided with a brake handle. The brake handle drives the brake assembly to tighten or loosen the traveling wheel via a brake cable.

[0006] Preferably, the brake assembly includes a brake seat, a spring, a brake plate, and brake pads. The brake seat is detachably connected to the vehicle frame by bolts. The brake seat is hollow inside. The spring is installed inside the brake seat. The upper end of the brake plate is movably inserted into the brake seat. The lower end of the brake plate is connected to the brake pads. One end of the spring is connected to the brake seat, and the other end of the spring is connected to the brake plate. The brake cable movably passes through the brake seat and connects to the brake plate, causing the brake pads at the lower end of the brake plate to move closer to or away from the wheel.

[0007] Preferably, both the brake seat and the rear end of the brake plate are provided with hook bolts, and the two ends of the spring are hooked onto the hook bolts.

[0008] Preferably, there are two sets of springs, arranged on both sides of the rear end of the brake plate.

[0009] Preferably, the push rod is provided with a computer bracket, and the frame is T-shaped.

[0010] The advantages of this utility model are: the design is simple in structure, easy to operate, quick in response, reliable in braking, requires no electrical modification, is fully mechanized in stopping, has low modification cost, and is highly practical. Attached Figure Description

Detailed Implementation

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0015] like Figures 1-3As shown, a track inspection anti-slip device includes a frame 1, a push rod 2, wheels 3, and a brake assembly 4. The frame 1 is movably placed on the track via the wheels 3. The lower end of the push rod 2 is connected to the frame 1, and the upper end of the push rod 2 is provided with a brake handle 21. The brake handle 21 drives the brake assembly 4 to engage or disengage the wheels 3 via a brake cable 22. Specifically, in this embodiment, the frame 1 is placed on the track via the wheels 3, and the push rod 2 is integrated on the frame 1 to facilitate the operator to push the frame 1 using the push rod 2 to inspect the track. To achieve the parking function, the brake assembly 4 is integrated on the frame 1. To facilitate the operation of the brake assembly 4, a brake handle 21 is provided on the push rod 2, and the brake handle 21 is connected to the movable part inside the brake assembly 4 via a brake cable 22. When the track inspection instrument is manually pushed, the operator holds both the push rod 2 and the brake handle 21. The brake cable 22 causes the movable part of the brake assembly 4 to disengage from the traveling wheel 3, allowing the track inspection instrument to move normally. When the operator removes their hand from the push rod 2, the brake handle 21 is no longer under pressure, the brake cable 22 loosens, and the movable part of the brake assembly 4, under the action of a spring or other force, grips the traveling wheel 3, preventing it from rotating and thus preventing the track inspection instrument from slipping. This design is simple in structure, easy to operate, responds quickly, and has reliable braking. It requires no electrical modifications, features fully mechanized stopping, has low modification costs, and is highly practical.

[0016] like Figures 2-4 As shown, the brake assembly 4 includes a brake seat 41, a spring 42, a brake plate 43, and a brake pad 44. The brake seat 41 is detachably connected to the frame 1 by bolts. The brake seat 41 is hollow inside. The spring 42 is installed inside the brake seat 41. The upper end of the brake plate 43 is movably inserted into the brake seat 41, and the lower end of the brake plate 43 is connected to the brake pad 44. One end of the spring 42 is connected to the brake seat 41, and the other end of the spring 42 is connected to the brake plate 43. The brake cable 22 movably passes through the brake seat 41 and connects to the brake plate 43, causing the brake pad 44 at the lower end of the brake plate 43 to move closer to or away from the travel wheel 3. Specifically, when driving, the operator pushes the frame 1 along the track. While pushing the frame 1, the operator grips the brake lever 21, causing the brake cable 22 to tighten. The brake cable 22 causes the front end of the brake plate 43 to move away from the travel wheel 3, at which time the spring 42 is compressed. When parking is required, the operator only needs to release the brake lever 21. After the brake cable 22 is no longer under force and relaxes, the spring 42 returns to its original state from compression, which in turn drives the front end of the brake plate 43 to move closer to the travel wheel 3, so that the brake pad 44 abuts against the travel wheel 3, completing the braking operation and automatically braking. This avoids the safety hazards caused by the passive braking device being easily forgotten after the stop inspection.

[0017] like Figures 2-4As shown, both the brake seat 41 and the rear end of the brake plate 43 are provided with hook bolts 411, and both ends of the spring 42 are hooked onto the hook bolts 411. Specifically, the hook bolts 411 are used to hold the spring 42 in place, making it easy to replace when the spring 42 loses elasticity, and the replacement operation is simple and convenient.

[0018] like Figure 4 As shown, there are two sets of springs 42, which are arranged on both sides of the rear end of the brake plate 43. The two sets of springs 42 provide sufficient elastic support for the brake plate 43 when braking, ensuring that the brake pad 44 can firmly abut against the traveling wheel 3 to complete the braking operation.

[0019] like Figure 1 As shown, the push rod 2 is equipped with a computer bracket 23 for supporting the computer used for testing, making it more convenient to use. The frame 1 is T-shaped.

[0020] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
