Description

Technical Field

[0001] The utility model relates to the field of maintenance tools, and more specifically, to a maintenance tool vehicle with an assembleable high-altitude work guardrail. Background Art

[0002] During on-site maintenance, maintenance personnel often need to climb to the repair location to perform operations. Existing tool carts only have basic tool storage functions, but lack the additional functions to assist maintenance personnel in ascending and performing maintenance operations. Once maintenance personnel need to perform maintenance at a higher location, they can only carry tools such as ladders to complete the maintenance.

[0003] If maintenance personnel climb onto a cart or stand on it while performing maintenance operations, they could fall, potentially causing an accident. However, installing a guardrail on the maintenance cart would not only prevent personnel from reaching the top of the cart, but also hinder the cart's ability to pass through. Folding guardrails require a complex folding and unfolding mechanism, making them prone to malfunction. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a maintenance tool vehicle with an assembleable high-altitude work guardrail, so as to solve the problem that the prior maintenance vehicle has no guardrail.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A maintenance tool vehicle with an assembleable high-altitude work guardrail, comprising a maintenance vehicle, a guardrail clamp, and a guardrail assembly;

[0007] The upper surface of the maintenance vehicle is rectangular, and guardrail clips are installed on the four corners of the upper surface of the maintenance vehicle;

[0008] The guardrail assembly includes four guardrail posts, two short guardrail rods, and two long guardrail rods;

[0009] The guardrail posts are installed on the guardrail clamps, the short guardrail rods and the long guardrail rods are fixed on the guardrail posts, and the guardrail posts, the short guardrail rods and the long guardrail rods are located in three directions perpendicular to each other.

[0010] When personnel need to climb to a maintenance location for operation, they first install the guardrail posts on the guardrail clamps, then install the short and long guardrail bars on the guardrail posts to quickly complete the guardrail installation. This simple structure is easy to install and remove, solving the technical problems of fixed guardrails that affect passability and folding guardrails that are complex structures.

[0011] A further technical solution is that the guardrail clamp includes a mounting seat and a quick locking device;

[0012] The quick lock device is installed on a mounting base, and the mounting base is installed on the upper surface of the maintenance vehicle.

[0013] The quick lock device has the characteristics of simple installation and disassembly and reliable structure, and is very suitable for the installation of guardrail posts.

[0014] A further technical solution is that a limit ring is provided on the guardrail post, and the diameter of the limit ring is larger than the diameter of the guardrail post;

[0015] Two mounting holes are provided on the short guardrail rod and the long guardrail rod. The distance between the mounting holes corresponds to the distance between the guardrail posts. The diameter of the mounting holes is larger than the diameter of the guardrail posts and smaller than the diameter of the limiting ring.

[0016] After the guardrail posts are installed and fixed, pass the mounting holes of the short guardrail rods and the long guardrail rods through the guardrail posts. The mounting holes will be stuck on the limit rings. At this time, the installation of the short guardrail rods and the long guardrail rods is completed.

[0017] A further technical solution is that the maintenance tool cart also includes an elastic pipe buckle;

[0018] The elastic tube buckle is installed on the upper surface of the maintenance vehicle, and the size of the elastic tube buckle corresponds to the size of the guardrail column, the short guardrail rod and the long guardrail rod.

[0019] The function of the elastic tube buckle is to facilitate the storage of the guardrail assembly. When the maintenance vehicle is moving, the guardrail assembly is clamped on the upper surface of the maintenance vehicle to prevent the guardrail assembly from shaking.

[0020] A further technical solution is that the maintenance tool cart also includes a work surface;

[0021] At least two elastic column tube buckles are installed on the lower surface of the work surface;

[0022] The work surface is not smaller than the upper surface of the maintenance vehicle and can be rotatably mounted on the upper surface of the maintenance vehicle. After the work surface is rotated and unfolded, the guardrail column close to the lower surface of the work surface can be clamped in the elastic column pipe buckle.

[0023] The work surface serves two purposes. First, since the elastic pipe clips and guardrail components are mounted on the top surface of the maintenance vehicle, the top surface is uneven when the vehicle is in use. The addition of the work surface provides a flat surface for subsequent work. Second, when the work surface is rotated and unfolded, it provides support for the guardrail posts, making them more stable.

[0024] A further technical solution is that the maintenance vehicle includes a climbing ladder, a ground brake, and anti-dumping auxiliary wheels;

[0025] The climbing ladder can be movably mounted on the side of the cart. The climbing ladder can be fixedly supported on the side of the cart when in use and stored on the side of the cart when not in use.

[0026] The floor brake is arranged at the bottom of the cart, and the number of the floor brakes is more than two;

[0027] The anti-dumping auxiliary wheel includes an extension rod and a support wheel;

[0028] There are two or more anti-dumping auxiliary wheels, and the anti-dumping auxiliary wheels are arranged on different sides of the bottom of the cart;

[0029] One end of the extension rod is rotatably connected to the bottom of the cart, and the other end of the extension rod is provided with a supporting wheel.

[0030] When maintenance personnel need to perform maintenance at a high place, they can install a ladder on the side of the cart and climb up to the top of the cart from the ladder;

[0031] In order to prevent the cart from moving when maintenance personnel are climbing or repairing, a ground brake is installed at the bottom of the cart. At the same time, there are two ground brakes to prevent the cart from rotating.

[0032] The anti-dumping auxiliary wheels are mainly used to prevent the cart from tipping over.

[0033] Compared to existing technologies, the present invention offers at least the following advantages: It simplifies the guardrail into easily removable guardrail assemblies, enabling rapid installation and removal when personnel need to climb to a maintenance location. This addresses the technical issues of fixed guardrails hindering the vehicle's accessibility and the complex structure of foldable guardrails. Furthermore, the maintenance vehicle of the present application includes a ladder, floor brakes, and anti-rollover auxiliary wheels, providing stable support for maintenance personnel to safely operate on the vehicle's upper surface.
