[0017] The technical solutions of the present application will be described clearly and completely below with reference to the drawings, obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0018] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0019] As Figs. 1 to 3The utility model discloses a kind of lifting equipment for road lighting engineering construction, including vehicle body 1, vehicle body 1 top fixedly installed scissor lift 2, the top of scissor lift 2 is connected with construction platform 3, scissor lift 2 is used to drive construction platform 3 to lift, wherein, vehicle body 1 adopts four-wheel chassis structure, to facilitate the removal of construction platform 3, and scissor lift 2 is mainly composed of hydraulic cylinder and cross transmission rod, it can be used with existing structure, so do not make too much repetition.

[0020] In the embodiment, a plurality of guardrail base rods 4 are vertically welded around the periphery of the construction platform 3, and a downwardly recessed guide groove is formed along the length direction on the top of each guardrail base rod 4. The guide groove has a rectangular cross section, and a guardrail extension rod 5 matching in shape is slidably fitted in the guide groove. Adjacent guardrail extension rods 5 are connected by horizontally welded blocking rods 6 to form a closed guardrail frame structure. A lifting device is arranged between the guardrail extension rod 5 and the guardrail base rod 4. The lifting device can drive the guardrail extension rod 5 to slide along the length direction of the guide groove, so as to adjust the length of the guardrail frame structure in the longitudinal direction. In this way, when aerial work is performed, the height of the guardrail frame structure can be increased by lifting the guardrail extension rod 5, so as to reduce the risk of falling for workers. In addition, by arranging the liftable guardrail extension rod 5, when a worker enters the construction platform 3, the guardrail extension rod 5 can be adjusted to the lowest end, so that the worker can step into the construction platform 3. When aerial work is performed, the guardrail extension rod 5 can be lifted. In this way, the safety of aerial work can be ensured, and a safety door does not need to be additionally installed, so as to reduce the risk of falling of the worker caused by the loosening of the safety door.

[0021] The lifting device is composed of a driving arm 71, a base 72, and a connecting rod 73. The base 72 is welded to the outer side wall of the guardrail base rod 4 and extends outwardly and horizontally. The base 72 and the driving arm 71 are hingedly connected by two mutually parallel connecting rods 73. One end of the driving arm 71 close to the guardrail extension rod 5 is provided with a U-shaped clamping groove 711. A cylindrical clamping column 74 is welded to the corresponding position of the side wall of the guardrail extension rod 5. After the clamping column 74 is inserted into the clamping groove 711, the other end (i.e., the handle end 712 described below) of the driving arm 71 is pressed down, the guardrail extension rod 5 is pushed upwardly along the guide groove by the lever principle, so as to adjust the height of the guardrail. The base 72 is arranged at a position such that the driving arm 71 is installed on the outer side of the construction platform 3. Therefore, the lifting device does not occupy the space on the inner side of the construction platform 3, so as to reserve sufficient activity range for the worker.

[0022] In addition, in order to fix the lifted guardrail extension rod 5, a plurality of circular locking holes 51 are arranged on the rod body of the guardrail extension rod 5 in the length direction. A downward recessed placing groove 721 is arranged on the top of the base 72, and a cylindrical locking rod 12 is placed in the placing groove 721 and can be manually extracted. When the guardrail extension rod 5 is lifted to the target height, the operator takes out the locking rod 12 from the placing groove 721 and inserts it into the corresponding locking hole 51, so as to limit the falling of the guardrail extension rod 5. The side wall of the placing groove 721 is further provided with a radially extending embedding groove 722, and the embedding groove 722 is installed with a spring 8 and an arc-shaped clamping block 9. One end of the spring 8 is fixed on the bottom of the embedding groove 722, and the other end is connected with the clamping block 9. When the locking rod 12 is inserted into the placing groove 721, the clamping block 9 clamps the locking rod 12 under the action of the spring 8, so as to prevent the locking rod 12 from being lost when not in use.

[0023] In addition, the outer side wall of the guardrail base rod 4 is welded with an extension seat 10, and the extension seat 10 is provided with an upward protruding buckle 11 made of a material with elasticity, such as rubber or plastic. The driving arm 71 is outwardly extended at one end away from the guardrail extension rod 5 as a handle end 712, and the handle end 712 is in a columnar shape. When the driving arm 71 does not lift the guardrail extension rod 5, the end of the handle end 712 can be pressed into the buckle 11, and the deformation of the buckle 11 can fix the driving arm 71, so as to avoid unnecessary noise caused by the shaking of the driving arm 71 and the impact on the guardrail frame when the lifting device is moved.

[0024] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution according to the needs after reading the specification, but as long as the modifications are within the scope of the claims of the utility model, they are protected by the patent law.
