Description

TECHNICAL FIELD

[0001] The utility model relates to a car roof structure of inorganic room passenger elevator car. BACKGROUND

[0002] The elevator is the permanent transport equipment that its car runs in at least two columns vertical to the horizontal plane or with the inclination angle of 15 DEG to the plumb line, and the annual inspection period of the elevator is one year, the elevator should be overhauled every month in general daily maintenance, and the overhauling time is determined by the running condition and maintenance condition of the elevator, and the overhauling time should avoid the passenger flow peak period (generally at night), and will not affect the use of the household.

[0003] The traditional inorganic room elevator adopts the elevator car roof to make the maintenance platform, that is, the maintenance personnel directly stand on the car roof to overhaul the components such as the hoisting machine in the shaft. However, when the top layer height is too high, even if the car rises to the highest position, the maintenance personnel standing on the car roof still cannot overhaul the components such as the hoisting machine, or the shaft size is too small, and there is a safety hazard when the maintenance personnel overhauls on the car roof. Therefore, the corresponding technical scheme needs to be designed to solve the above problems. SUMMARY

[0004] The utility model discloses a car roof structure of inorganic room passenger elevator car, which is reasonable in structure, and the maintenance platform is arranged to facilitate the maintenance personnel to overhaul the components in the shaft. Moreover, the maintenance platform can be adjusted to a suitable position, so that the maintenance personnel can better contact the components to be overhauled, thereby bringing convenience to the overhaul operation and improving the practicability of the maintenance platform.

[0005] To achieve the above object, the utility model discloses a car roof structure of inorganic room passenger elevator car, which comprises a car roof plate and a maintenance platform.

[0006] The top of the car roof plate is symmetrically provided with two upper beams, the upper beam is a channel steel, and a plurality of threaded holes are formed in the top of the upper beam and are arranged at equal intervals along the length direction of the upper beam.

[0007] The maintenance platform is arranged on the top of the two upper beams, and the maintenance platform comprises a support plate and a guardrail arranged on the top of the support plate.

[0008] Preferably, the top of the upper beam is provided with a baffle, and the support plate is located between the baffles of the two upper beams.

[0009] Preferably, one side of the guardrail is provided with an entrance and exit, the bottom end of the entrance and exit is provided with a step pedal, the top end of the step pedal is fixedly connected with a supporting plate, and the bottom end of the step pedal is in contact with a car roof plate.

[0010] Preferably, the guardrail is welded by a plurality of round pipes.

[0011] Preferably, the notches of the two upper beams are oppositely arranged.

[0012] The utility model discloses an advantage and beneficial effect lie in: provide a kind of car roof structure of inorganic room passenger elevator car, its structure is reasonable, by setting up maintenance platform, to facilitate maintenance personnel to the component in shaft to carry out maintenance;And, the maintenance platform can be adjusted to suitable position, so that maintenance personnel can better contact the component needing to be overhauled, bring convenience for overhauling operation, improve the practicability of maintenance platform. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is the schematic diagram of the utility model.

[0014] Figure 2 It is Figure 1 The enlarged view of A in Fig. DETAILED DESCRIPTION

[0015] The specific embodiment of the utility model is further described in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0016] The technical scheme of the embodiment of the utility model is:

[0017] As Figure 1 And Figure 2 Shown, a kind of car roof structure of inorganic room passenger elevator car, including car roof plate 1 and maintenance platform;

[0018] The top of the car roof plate 1 is symmetrically provided with two upper beams 2, the upper beam 2 is a channel steel, and the top of the upper beam 2 is provided with a plurality of threaded holes 3, the plurality of threaded holes 3 are arranged at equal intervals along the length direction of the upper beam 2;

[0019] The maintenance platform is arranged at the top of the two upper beams 2, and the maintenance platform includes a supporting plate 4 and a guardrail 5 arranged at the top of the supporting plate 4, the supporting plate 4 is provided with two groups of fixing hole groups, the two groups of fixing hole groups correspond to the two upper beams 2 one by one, the fixing hole group includes a plurality of fixing holes 6, the fixing hole 6 is provided with a fastening bolt 7 threadedly connected with the threaded hole 3 of the corresponding upper beam 2.

[0020] When the position of the maintenance platform needs to be adjusted, the fastening bolt 7 is first unscrewed, then the maintenance platform is slid to the appropriate position, the fastening bolt 7 is screwed into the corresponding threaded hole 3 through the fixing hole 6 of the support plate 4, the support plate 4 is fixed with the upper beam 2 through the fastening bolt 7, and thus the maintenance platform is fixed on the roof panel.
