[0033] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. A lot of specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0034] See Figure 1 , in an embodiment of the present utility model, a horizontally translatable and liftable platform for a suspended monorail maintenance operation vehicle. The horizontally translatable scissor lift platform is a key device of the suspended monorail maintenance operation vehicle, and is suitable for the delivery of construction operation personnel of the maintenance operation vehicle and the transportation of maintenance equipment, tools and materials, and is used for the construction operation and rescue operation of the suspended monorail line of the maintenance operation vehicle.

[0035] See Figure 1 , a horizontally translatable and liftable platform for a suspended monorail maintenance operation vehicle includes a guardrail assembly 1, a lifting mechanism, a hydraulic system, an electric control system, and a horizontal translation slide 3. The lifting mechanism is arranged on the horizontal translation slide 3, the guardrail assembly 1 is arranged on the lifting mechanism, and the lifting mechanism is used to drive the guardrail assembly 1 to lift relative to the horizontal translation slide 3. In this embodiment, the structure of the lifting mechanism is not limited.

[0036] As an example, in this embodiment, the lifting mechanism is a hydraulic scissor lifting mechanism 2, and the hydraulic scissor lifting mechanism 2 includes a scissor mechanism 2a, a chassis 2b and a scissor hydraulic system 2c. The chassis 2b is fixed to the upper frame welding structure 3b of the slide, the scissor mechanism 2a is arranged on the chassis 2b, and the scissor mechanism 2a is connected to the guardrail assembly 1.

[0037] Specifically, see Figure 8 and Figure 9 , in an embodiment, the scissor mechanism 2a includes a lower guide chute 2e fixed to the chassis 2b and multiple groups of scissor structures. The scissor structure includes two intersecting scissor ribs, and the two scissor ribs are hinged at the intersection position, and the ends of the scissor ribs of adjacent scissor structures are hinged. One end of a scissor rib 2L of the lowermost scissor structure is hinged to the chassis 2b, and the other end of the other scissor rib 2m of the lowermost scissor structure is provided with a lower guide wheel 2h, and the lower guide wheel 2h can slide in the lower guide chute 2e. See Figure 13, the end of a shear fork rib 2j of the uppermost shear fork structure is hinged to the lower guardrail panel 1c, and an upper guide wheel 2g is provided at the end of another shear fork rib 2k of the uppermost shear fork structure. The upper guide wheel 2g can slide relative to the bottom surface of the lower guardrail panel 1c. Specifically, when setting, an upper guide chute can also be fixed to the bottom of the lower guardrail panel 1c to guide the moving direction of the upper guide wheel 2g. The upper guide wheel 2g can slide inside the upper guide chute so that the guardrail assembly 1 can lift and lower relative to the transverse sliding table 3. It should be noted that the setting method between the lower guardrail panel 1c and the uppermost shear fork structure can refer to Figure 9 , and the two are mirror images of each other, which will not be elaborated here.

[0038] In addition, it should be noted that there is no restriction on the setting method of the hydraulic cylinder for controlling the lifting. As long as it can control the lifting of the shear fork mechanism 2a. As an example, in this embodiment, both ends of the hydraulic cylinder 2c1 for controlling the lifting are hinged. One end is indirectly hinged to the end of the shear fork rib 2m connected to the lower guide wheel 2h, and the other end is indirectly hinged to the cross position of the two shear fork ribs of the lowermost shear fork structure. Specifically, in one embodiment, refer to Figure 11 and Figure 12 , an end cross beam 2m1 is connected to the end of the shear fork rib 2m.

An intermediate cross beam connecting ear 2m4 is installed on the intermediate cross beam 2m3. The other end of the hydraulic cylinder 2c1 for controlling the lifting is movably connected to the intermediate cross beam connecting ear 2m4. When the hydraulic cylinder 2c1 for controlling the lifting expands and contracts, it drives the shear fork mechanism 2a to lift and lower, and further the guardrail assembly 1 above the shear fork mechanism 2a lifts and lowers. It should be noted that except for the lowermost shear fork structure, end cross beams are provided at the ends of the shear fork ribs on one side of other shear fork structures, and an end cross beam connecting ear is fixed on each end cross beam. Intermediate cross beams are provided at the cross positions of other shear fork structures, and an intermediate cross beam connecting ear is fixed on each intermediate cross beam. The hydraulic cylinder 2c1 for controlling the lifting can be selectively installed between any group of end cross beam connecting ears and intermediate cross beam connecting ears so that the hydraulic cylinder 2c1 for controlling the lifting expands and contracts, driving the shear fork mechanism 2a to lift and lower, and further the guardrail assembly 1 above the shear fork mechanism 2a lifts and lowers.

For example, in some other embodiments, the lifting mechanism includes four lifting sleeves fixed at the four corners of the chassis 2b. The lifting sleeve includes a large sleeve fixed to the chassis 2b and a small sleeve fixed to the lower guardrail panel 1c. The small sleeve is slidably connected to the large sleeve, and the small sleeve can lift and lower relative to the large sleeve.
