Description

Technical Field

[0001] The utility model relates to the field of maintenance tools, and more specifically, to a detachable high-altitude work guardrail and a maintenance tool vehicle using the 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 the cart or stand on the cart to perform maintenance operations, they may fall and cause safety accidents. However, if guardrails are installed on the maintenance cart, when no one is standing on it, the guardrails will affect the cart's passability and cause inconvenience to the user. Utility Model Content

[0004] The utility model overcomes the problem that the existing cart has no guardrail and the installation of the guardrail is inconvenient, and provides a repair tool cart with a detachable high-altitude work guardrail and the use of the guardrail, in the hope of solving the above problems.

[0005] In order to solve the above technical problems, the present invention provides a detachable high-altitude working guardrail:

[0006] A detachable guardrail for high-altitude operations, including left and right guardrails, and front and rear guardrails;

[0007] There are two left and right guardrails, which can be rotatably mounted on the same rectangular plane. The lengths of the left and right guardrails are consistent with the lengths of a pair of opposite sides of the rectangular plane.

[0008] There are two front and rear guardrails, each comprising two front and rear splicing assemblies, each of which can be rotatably mounted on a left or right guardrail, and each of which has a consistent mounting height.

[0009] The length of the front and rear splicing components is half of the length between the left and right guardrails, and the front and rear splicing components can be fixedly connected.

[0010] Since the left and right guardrails can be rotatably mounted on a rectangular plane, the front and rear splicing components can be rotatably mounted on different left and right guardrails respectively. When no one is standing on the stroller, the left and right guardrails are stored on the rectangular plane, and the front and rear splicing components are stored on the left and right guardrails, which will not cause inconvenience to the use of the stroller.

[0011] In use, first rotate and raise the left and right guardrails. After the left and right guardrails are raised, rotate the front and rear splicing components by 90 degrees, and fixedly connect the front and rear splicing components after rotation by 90 degrees. After the front and rear splicing components are fixedly connected, the positions of the left and right guardrails and the front and rear guardrails are fixed, providing protection and preventing falls.

[0012] A further technical solution is that the rectangular plane is hinged to the left and right guardrails;

[0013] The front and rear splicing components are hinged to the left and right guardrails.

[0014] An even further technical solution is that the front and rear splicing components are fixed using a bolt.

[0015] An even further technical solution is that the left and right guardrails include two left and right splicing components;

[0016] The left and right splicing components are rotatably connected, and a fixed bolt and a damping hinge are provided between the left and right splicing components.

[0017] Since the height of the front and rear guardrails is determined by the height of the left and right guardrails, and in order to prevent people from falling, it is best for the left and right guardrails to have a certain height. However, if the height of the left and right guardrails is too high, it will cause problems such as inconvenient storage and installation. Therefore, the left and right guardrails are split into two left and right splicing components, and the left and right guardrails are formed by rotating and fixing the left and right splicing components, which can obtain left and right guardrails with a relatively high height while minimizing the size of the left and right splicing components.

[0018] An even further technical solution is that the left and right guardrails and the front and rear guardrails are all designed with hollow-outs.

[0019] The hollow-out design can reduce the weight of the left and right guardrails and the front and rear guardrails, and facilitate the storage of the front and rear guardrails on the left and right guardrails.

[0020] The present utility model also provides a maintenance tool cart, including the detachable high-altitude operation guardrail and the cart as described above

[0021] There are 4 universal wheels at the lower part of the cart, and the upper part of the cart is a flat surface, and the high-altitude operation guardrail is installed on the flat surface.

[0022] A further technical solution is that the maintenance tool cart further includes a climbing ladder, a ground brake, and anti-tipping auxiliary wheels;

[0023] The climbing ladder is movably installed on the side of the cart, and the climbing ladder can be fixedly supported on the side of the cart during use and stored on the side of the cart when not in use;

[0024] The ground brake is arranged at the bottom of the cart, and the number of the ground brakes is more than two;

[0025] The anti-tipping auxiliary wheels include an extension rod and a support wheel;

[0026] The number of the anti-tipping auxiliary wheels is more than two, and the anti-tipping auxiliary wheels are arranged on different sides of the bottom of the trolley;

[0027] One end of the extension rod is rotatably connected to the bottom of the trolley, and the other end of the extension rod is provided with a support wheel.

[0028] When maintenance personnel need to perform maintenance on high places, the maintenance personnel can install a climbing ladder on the side of the trolley and climb from the climbing ladder to the top of the trolley;

[0029] In order to prevent the trolley from moving when the maintenance personnel climb or perform maintenance, a ground brake is provided at the bottom of the trolley. At the same time, the number of the ground brakes is 2, which can prevent the trolley from rotating and other situations.

[0030] The main function of the anti-tipping auxiliary wheel is to prevent the trolley from tipping over.

[0031] Compared with the prior art, the utility model has at least the following beneficial effects: by rotatably installing the left and right guardrails on a rectangular plane and rotatably installing the front and rear splicing components on different left and right guardrails respectively, the left and right guardrails can be stored on the rectangular plane and the front and rear splicing components can be stored on the left and right guardrails when there is no one standing on it usually, which will not cause inconvenience to the use of the trolley. When in use, first rotate and support the left and right guardrails, and fixedly connect the front and rear splicing components. After the front and rear splicing components are fixedly connected, the positions of the left and right guardrails and the front and rear guardrails are fixed, which has the effect of protection and preventing falling.
