Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and in particular relates to a portable magnetic steel guardrail climbing device. Background Art

[0002] Highway steel guardrails are usually set up near the shoulder or roadside of the highway to prevent vehicles from deviating from the road and reduce the risk of vehicles running off the highway. At the same time, highway steel guardrails also have the function of guiding vehicles to the correct information.

[0003] When maintenance workers need to inspect highway slopes, bridges, protective nets and other structures, they usually need to climb over steel guardrails. However, steel guardrails are relatively high, and it is not easy for short or female workers to climb over them. Therefore, some maintenance workers who have difficulty climbing over steel guardrails usually carry portable ladders to help them climb over them. The disadvantages of portable ladders are as follows:

[0004] (1) The use of portable ladders requires the cooperation of multiple people. Because portable ladders do not have a fixing device, when maintenance workers use portable ladders to climb over the steel guardrails of highways, they need other people to manually fix the portable ladder so that the maintenance workers can safely use the portable ladder to climb over the steel guardrails.

[0005] (2) The stability of portable ladders is poor. When inspecting in rainy days, the stability of portable ladders will be greatly reduced. Although the portable ladder is manually fixed by others, there will be water marks on the steel guardrails of the highway in rainy days. If you are not careful, the portable ladder will slide sideways due to the reduced friction with the steel guardrails of the highway.

[0006] (3) Portable ladders are difficult to operate. Although portable ladders are more portable, they require maintenance staff to fully extend them before they can be used. During recycling, since portable ladders use a fully mechanical recycling mechanism, each mechanical component needs to be accurately adjusted to the preset position before the portable ladder can be recycled.

[0007] Portable ladders have a high safety risk. Portable ladders have many mechanical parts, so when maintenance workers use portable ladders to climb over steel guardrails, there is a safety risk that their fingers or arms may be injured by the mechanical parts of the portable ladder. Utility Model Content

[0008] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a portable magnetic steel guardrail climbing device, the purpose of which is to enable a single maintenance worker to carry and climb over the steel guardrail of the highway easily, and the device is easy to operate and has good stability and safety.

[0009] In order to achieve the above purpose, the specific scheme of the utility model is as follows:

[0010] Portable magnetic steel guardrail climbing device, including a first-level step, a second-level step and a third-level step. The first-level step is formed by connecting a first base and a first support block into a square box shape. The second-level step includes a second base, a second support block and a first electric push rod. One side of the second base is connected to one side of the first base. The second support block is arranged on the top of the second base. Two first electric push rods are respectively installed inside both sides of the second base. The push rods of the two first electric push rods are respectively connected to both sides of the bottom of the second support block. The third-level step includes a third base, a third support block and a second electric push rod. One side of the third base is connected to one side of the second base. The third support block is arranged on the top of the third base. Two second electric push rods are respectively installed inside both sides of the third base. The push rods of the two second electric push rods are respectively connected to both sides of the bottom of the third support block. The length of the push rod of the second electric push rod is greater than the length of the push rod of the first electric push rod.

[0011] Furthermore, a handle is provided on the outer side of the second base.

[0012] Furthermore, it also includes a control module, a first power supply, a second power supply and a third power supply. The control module and the first power supply are respectively arranged inside the first base. The first power supply provides the working voltage for the control module. The second power supply is arranged inside the second base and provides the working voltage for the first electric push rod. The third power supply is arranged inside the third base and provides the working voltage for the second electric push rod. Electromagnets are respectively provided on the tops of the second support block and the third support block. The electromagnets, the first electric push rod and the second electric push rod are respectively connected to the control module.

[0013] Advantages of the present utility model

[0014] (1) The portable magnetic steel guardrail climbing device of the present utility model can be carried by a single person through the handle. When it is necessary to climb over the steel guardrail of the expressway, it can automatically lift the second-level and third-level steps according to the control instructions of the maintenance staff, so as to enable a single person to climb over the steel guardrail of the expressway.

[0015] (2) The climbing device adopts a stepped structure design. Whether it is a rainy-day inspection or a sunny-day inspection, by installing electromagnets at the tops of the second-level and third-level steps, the steel guardrail can be attracted by magnetic force, which greatly ensures the stability of the climbing device during use.

[0016] (3) The operation of the climbing device is simple. Through the control chip and the electric push rod, the second-level and third-level steps can be lifted and retracted portably and quickly. Without precise additional adjustment of the structural components, a series of operations can be automatically completed.

[0017] (4) The safety risk of this over - climbing device is low. When maintenance staff use this over - climbing device to climb over the steel guardrail of the highway, only the soles of their shoes come into contact with the device, and the first - level, second - level, and third - level steps of the over - climbing device are all flat planes, so the safety risk of maintenance staff being injured by components is relatively low.
