Description

Technical Field

[0001] The utility model relates to the technical field of bridge inspection vehicles, and specifically relates to an adjustable anti - top mechanism for a telescopic bridge inspection vehicle. Background Technique

[0002] With the development of the company, more and more attention has been paid to the safety performance of bridge inspection vehicles. The mechanical structure is increasingly inclined to be simplified. For the design of the existing telescopic truss of the company, nylon wheels are used for the guiding wheels, which are clamped on both sides, and flat wheels are used for the top wheels for anti - topping. When the telescopic truss extends a certain distance and the gravity exceeds the load - bearing wheels, it plays a role in preventing overturning, effectively ensuring the safety of the entire inspection vehicle truss system. As Figure 1 shown in the structural diagram of the existing - technology bridge inspection vehicle, it includes a main truss and a telescopic truss, and the telescopic truss is arranged inside the main truss.

[0003] Combined with the existing - technology solutions, some problems found during on - site debugging and construction are summarized as follows:

[0004] 1. During equipment debugging and on - site construction, the overall truss cannot be completely horizontal, which leads to a certain inclination of the truss. The gap between the anti - top wheel and the load - bearing wheel should not be too small (the telescoping is likely to get stuck); at the same time, it should not be too large, otherwise, after the telescopic truss extends, the overturning angle will be too large, posing a safety hazard.

[0005] 2. Nylon wheels are prone to wear; too large a gap between the anti - top wheel and the load - bearing wheel will also cause the clamping edge to be worn out directly during operation due to the uneven on - site conditions.

[0006] Therefore, in view of the above - mentioned technical solutions, it is necessary to propose an adjustable anti - top mechanism for a telescopic bridge inspection vehicle. Content of the Utility Model

[0007] The purpose of the utility model is to provide an adjustable anti - top mechanism for a telescopic bridge inspection vehicle to solve the above problems.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] An adjustable anti - top mechanism for a telescopic bridge inspection vehicle includes a main truss, a telescopic truss, a traveling mechanism, a moving rail, load - bearing wheels, and an anti - top wheel structure. A number of load - bearing wheels are arranged at the inner bottom of the main truss. The telescopic truss is arranged inside the main truss and mounted on the load - bearing wheels. The anti - top wheel structure is installed at the inner top of the middle position of the main truss. The moving rail is installed at the lower part of the main truss. The traveling mechanism is installed on the telescopic truss. The output end of the traveling mechanism is connected with a moving wheel, and the moving wheel is in rolling connection with the moving rail.

[0010] Preferably, slope plates are provided at both upper ends of the telescopic truss.

[0011] Preferably, the moving wheels are V-groove wheels.

[0012] Preferably, the moving rails are V-shaped channel steels.

[0013] Preferably, the anti-top wheel structure includes a fixing plate, an anti-top wheel, a support frame, a mounting frame and a gasket. The anti-top wheel is fixed to the mounting frame, and the mounting frame is connected to the fixing plate by bolts through the gasket and the support frame.

[0014] Preferably, the number of the gaskets is set according to the usage requirements.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the present utility model is installed and the extension distance dimension is designed well, the approximate position of the anti-top wheel can be determined, so that a slope plate can be welded correspondingly. The adjusting gasket can be adjusted during debugging. When reaching the working position (the final extended state), the anti-top wheel just abuts against the telescopic truss with the slope plate, so there will be no tipping angle, and there will be no shaking when the operator works outside the telescopic truss. The overall safety is better than that of the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The embodiments of the present utility model are described in detail below with reference to the drawings, but the present utility model can be implemented in many different ways defined and covered by the claims.

[0027] The following combines the attached Figure 2-6 A further detailed description of the present utility model is given.

[0028] As Figure 2-6 shown, an embodiment provided by the present utility model: an adjustable anti - top mechanism for a telescopic bridge inspection vehicle, including a main truss 1, a telescopic truss 2, a traveling mechanism 3, a moving rail 4, a carrying wheel 5, and an anti - top wheel structure 6. A plurality of carrying wheels 5 are arranged at the inner bottom of the main truss 1. The telescopic truss 2 is arranged inside the main truss 1 and mounted on the carrying wheels 5. The anti - top wheel structure 6 is installed at the inner top of the middle position of the main truss 1. The moving rail 4 is installed at the lower part of the main truss 1. The traveling mechanism 3 is installed on the telescopic truss 2. The output end of the traveling mechanism 3 is connected with a moving wheel 8, and the moving wheel 8 is in rolling connection with the moving rail 4.

[0029] Further, slope plates 9 are provided at both upper ends of the telescopic truss 2.

[0030] Further, the moving wheels 8 are V-groove wheels.

[0031] Further, the moving rails 4 are made of V-groove steel channels.

[0032] Further, the anti-top wheel structure 6 includes a fixing plate 601, an anti-top wheel 602, a support frame 603, a mounting frame 604 and a gasket 605. The anti-top wheel 602 is fixed to the mounting frame 604. The mounting frame 604 is connected to the fixing plate 601 by bolts 606 through the gasket 605 and the support frame 603.

[0033] Further, the number of the gaskets 605 is set according to the usage requirements.

[0034] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the present utility model is installed and the extending distance dimension is designed well, the approximate position of the anti-top wheel can be determined, and thus a slope plate 9 can be welded correspondingly. The adjusting gasket 605 can be adjusted during debugging. When reaching the working position (the final extended state), the anti-top wheel just abuts against the telescopic truss with the slope plate, so there will be no tipping angle, and there will be no shaking when people work outside the telescopic truss. The overall safety is better than that of the prior art.

[0035] The moving wheels 8 are V-groove wheels, which can effectively reduce a series of problems caused by wear;

[0036] Weld a slope plate for the estimated stroke and in-place dimension of the telescopic truss as a limit and an anti-top fulcrum; adjust the height dimension by adding gaskets to the anti-top wheels to perform the anti-top and limit functions within a reasonable range.

[0037] Working principle:

[0038] A plurality of load-bearing wheels 5 are provided at the inner bottom of the main truss 1. The telescopic truss 2 is arranged inside the main truss 1 and mounted on the load-bearing wheels 5. The anti-top wheel structure 6 is installed at the inner top of the middle position of the main truss 1. The moving rails 4 are installed at the lower part of the main truss 1. The traveling mechanism 3 is installed on the telescopic truss 2. The output end of the traveling mechanism 3 is connected with a moving wheel 8, and the moving wheel 8 is in rolling connection with the moving rail 4.

[0039] During work, the output end of the traveling mechanism 3 drives the moving wheel 8 to rotate, and the moving wheel 8 moves along the moving rail 4, so that the telescopic truss 2 extends. When reaching the end, the anti-top wheel 602 contacts the slope plate 9.

[0040] During debugging or installation, before the telescopic truss 2 enters the main truss 1, first install the anti - top wheel 602 in advance, but do not install the adjusting gasket 605. Ensure that the height allows the telescopic truss 2 to move smoothly into the main truss 1. After the telescopic truss 2 is adjusted to the parked state, then the fitter adds the gasket 605 of the anti - top wheel 602 and adjusts it until the anti - top wheel 602 achieves the exact anti - top effect when in the extended state, ensuring that the overall truss is basically horizontal at the working position.

[0041] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above - mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non - restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
