Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a matching guardrail on a hydraulic trestle. Background Art

[0002] The trestle is high from the ground, so guardrails must be installed on both sides of the hydraulic trestle to protect the workers during construction. The existing standard height of the guardrail is 1.2m. However, if the guardrail adopts the standard height of 1.2m, it will affect the rotation of the excavator when working on the trestle.

[0003] At present, most of the guardrails on the market are non-flippable and have poor adaptability. When the guardrail is too high and affects the construction, it needs to be removed, which has poor safety. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a supporting guardrail on a hydraulic trestle. The guardrail structure is composed of two parts, so that the upper guardrail can be flipped inward or outward, thereby reducing the height of the guardrail and facilitating construction. At the same time, it can ensure construction safety, simple operation, and easy use, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guardrail on a hydraulic trestle, comprising a lower guardrail and an upper guardrail, wherein the connection between the lower guardrail and the upper guardrail has a plurality of connection nodes, each connection node has two mounting holes, and when bolts are inserted into the mounting holes at the same position of a plurality of connection nodes, the upper guardrail can be flipped downward; when the upper guardrail maintains a vertical position on the upper side of the lower guardrail, bolts are movably inserted into the two mounting holes at at least one connection node.

[0006] As a preferred technical solution of the utility model, the lower guardrail is an L-shaped structure. When only the bolts are movably inserted into the mounting hole on the left side of the connection node, the upper guardrail is flipped over from the inside of the lower guardrail.

[0007] As a preferred technical solution of the utility model, when only the bolts are movably inserted into the mounting hole on the right side of the connection node, the upper guardrail is flipped over from the outside of the lower guardrail.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The guardrail on the hydraulic trestle example of the utility model adopts a two-part guardrail structure, so that the upper guardrail can be flipped inward or outward, thereby reducing the height of the guardrail, facilitating construction, and ensuring construction safety, simple operation, and easy use.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-4 The utility model provides a technical solution: a supporting guardrail on a hydraulic trestle, comprising a lower guardrail 1 and an upper guardrail 2, wherein the connection between the lower guardrail 1 and the upper guardrail 2 has a plurality of connection nodes, each connection node has two mounting holes, and when bolts 3 are inserted into the mounting holes at the same position of the plurality of connection nodes, the upper guardrail 2 can be flipped downward; when the upper guardrail 2 is kept in a vertical position on the upper side of the lower guardrail 1, bolts 3 are movably inserted into the two mounting holes at at least one connection node, the lower guardrail 1 and the upper guardrail 2 are connected by the bolts 3, and the upper guardrail 2 can be flipped by removing the bolts 3 on the same side, thereby reducing the height of the guardrail and facilitating construction.

[0017] Furthermore, the lower guardrail 1 is an L-shaped structure. When only the bolt 3 is inserted into the mounting hole on the left side of the connection node, the upper guardrail 2 is turned over from the inside of the lower guardrail 1. When turning inward, Figure 3 As shown: remove the outer bolts 3 of the connection node to flip the upper guardrail 2 inward.

[0018] Further, when only the bolt 3 is inserted into the mounting hole on the right side of the connection node, the upper guardrail 2 is turned over from the outside of the lower guardrail 1; when turning outward, as shown in FIG. Figure 4 As shown: remove the inner bolt 3 of the connection node to flip the upper outer side of the upper guardrail 2.

[0019] When using:

[0020] When turning inward, Figure 3As shown: remove the outer bolts 3 of the connection node to flip the upper guardrail 2 inward;

[0021] When turned outward, Figure 4 As shown: remove the inner bolt 3 of the connection node to flip the upper outer side of the upper guardrail 2.

[0022] The utility model adopts a two-part guardrail structure, so that the upper guardrail 2 can be turned inward or outward, thereby reducing the height of the guardrail, facilitating construction, and ensuring construction safety, simple operation, and easy use.
