[0007] A protective cover; the support seat is fixedly provided with a fixed cylinder, and the hydraulic rod is located in the fixed cylinder; the protective cover is slidably sleeved on the fixed cylinder, and the protective cover is connected with the support seat through the elastic connecting assembly; the inner wall of the protective cover corresponds to the workbench.

[0008] As an improvement, the inclination adjusting assembly comprises a lifting plate and an adjusting block, the lifting plate is slidably arranged in the groove, and the adjusting block is provided with two, and the two adjusting blocks are fixedly connected below the lifting plate.

[0009] As improved, the supporting seat is provided with an adjusting screw inside rotating, the adjusting screw is located in the groove, and the lifting plate is threadedly connected to the adjusting screw.

[0010] As improved, the elastic connecting assembly comprises a spring and a fixed rod, the fixed rod is fixedly connected to the supporting seat and slidably penetrates into the protective cover, and the spring is located between the protective cover and the supporting seat and is sleeved on the fixed rod.

[0011] As improved, the protective cover is provided with a limiting block fixedly connected to the upper end of the fixed rod.

[0012] As improved, the inner wall of the protective cover is fixedly provided with a fixed plate.

[0013] The bridge construction lifting work platform has the advantages that:

[0014] 1. The groove is arranged at the bottom of the supporting seat, and the inclined adjusting assembly is slidably arranged in the groove; the inclined adjusting assembly is arranged, so that the supporting seat can be horizontally adjusted when the ground of the bridge is uneven, thereby increasing the levelness of the workbench and avoiding affecting the normal work of the workbench.

[0015] 2. The protective cover is slidably sleeved on the fixed cylinder, and the inner wall of the protective cover corresponds to the workbench; the protective cover is arranged separately from the workbench, so that the protective cover can protect the construction tools when the lifting work platform is moved, and the construction tools can be prevented from falling due to vibration and the like.

[0021] The utility model is further illustrated below with reference to the drawings.

[0022] According to Figures 1-4 As shown in the figure: the utility model provides a bridge construction is with lifting work platform: including support seat 1, support seat 1 is fixedly provided with hydraulic machine 9, and the working end of hydraulic machine 9 is fixedly connected with workbench 3, still including:

[0023] Groove 5 and inclination adjustment assembly, groove 5 is set up in support seat 1 bottom, and groove 5 is provided with two groups;Groove 5 is arranged at the both sides of support seat 1, and inclination adjustment assembly is slidably arranged in groove 5;

[0024] Protective cover 4;Support seat 1 is fixedly provided with fixed cylinder 2, and hydraulic rod is located in fixed cylinder 2;Protective cover 4 is slidably sleeved on fixed cylinder 2, and protective cover 4 is connected with support seat 1 by elastic connecting component;The inner wall of protective cover 4 corresponds with workbench 3.

[0025] As Figure 3 Shown, inclination adjustment assembly includes lifting plate 7, adjusting block 6, lifting plate 7 is slidably arranged in groove 5, adjusting block 6 is provided with two, and two adjusting blocks 6 are fixedly connected below lifting plate 7.Support seat 1 is rotatably provided with adjusting screw 8, and adjusting screw 8 is located in groove 5, and lifting plate 7 is screw-connected on adjusting screw 8;Lifting plate 7 is the cuboid structure corresponding with groove 5, and lifting plate 7 and the inner wall of groove 5 mutually fit, can limit the rotation of lifting plate 7, to convert the rotation of adjusting screw 8 into the movement of lifting plate 7, and drive adjusting block 6 to move, make the horizontal state of support seat 1 change, to offset the inclination of bridge pavement, make workbench 3 can keep level.

[0026] As Figure 4 Shown, elastic connecting component includes spring 10, fixed rod 11, and fixed rod 11 is fixedly connected on support seat 1, and fixed rod 11 is slidably inserted into protective cover 4;Spring 10 is located between protective cover 4 and support seat 1, and spring 10 is sleeved on fixed rod 11, can exert force to protective cover 4, guarantee that protective cover 4 is in the position of being more fixed.
