Description

Z-shaped elevator guide rail connecting piece

Technical Field

The utility model relates to an elevator guide rail installation technical field, more specifically the utility model relates to a Z type elevator guide rail connecting piece that says so.

Background

In the process of assembling the elevator, in order to ensure the normal and smooth running of the elevator, guide rails are generally required to be installed on the elevator, and the length of each guide rail is fixed, so that the guide rails are required to be connected through a connecting plate so as to reach the specified height. The existing guide rail connecting plate is usually a steel plate, which is used as a lining plate and is tightly attached to the end parts of two guide rails to be connected, and 8 standard bolts are screwed down to enable a guide rail track to be continuously extended or lifted. The steel plate is made of hot-rolled flat steel as a raw material, and is thick for ensuring the connection strength, so that the material cost is high, multiple machining devices are needed for sawing, milling, drilling and other multiple machining processes, the energy consumption is high, the machining cost is high, and in addition, wastewater can be generated in the machining process, the environment is influenced, and the environment is polluted.

Therefore, how to provide an elevator guide rail connecting piece which has simple structure, convenient processing, low manufacturing cost, light weight and safe installation is a problem which needs to be solved urgently by the technical personnel in the field.

The beneficial effects of the utility model are that, protruding edge is equivalent to the strengthening rib of connecting plate body, and the existence on protruding edge makes the connecting plate body be difficult to buckle, increases the intensity of connecting plate body, compares in original guide rail connecting piece, and the connecting plate body is thinner, is favorable to the energy saving, adopts mold processing integrated into one piece, improves production efficiency to simple structure.

Preferably, the convex edge and the connecting plate body are in arc transition, and the radius of the arc is 5 mm. The beneficial effect who adopts above-mentioned scheme is that, the design of fillet makes the convex edge more firm with being connected between the connecting plate body.

Preferably, the connecting plate body is made of Q355 material. Adopt above-mentioned scheme's beneficial effect is, high-quality carbon steel is more ordinary carbon steel stable performance, mechanical properties is good, impurity is few, the defect is few, metal consumption step-down simultaneously, the installation is light, the weight of the ordinary carbon steel's of Q235 that originally uses connecting plate body is heavy, potential safety hazard when installing, steel tensile strength lower limit is 370Mpa, yield strength is 235, change Q355 low alloy high strength structural steel now into, the tensile strength lower limit is 450Mpa, yield strength is 355, intensity is better, the quality is lighter, the installation is safe.

Preferably, the surface of the connecting plate body is galvanized. Adopt above-mentioned scheme's beneficial effect is that, all surfaces all adopt the galvanizing treatment, compare in prior art's one side paint one side and expose and more can prevent that the connecting plate body from rustting.

Preferably, the number of the fixing holes is eight, and the diameter of the fixing hole is 8 mm. The beneficial effects of adopting above-mentioned scheme are that, eight be the quantity of best fixed orifices, too many can destroy connecting plate body intensity, too few plays the effect of unable fixed guide.

Can know via foretell technical scheme, compare with prior art, the utility model discloses a Z type elevator guide rail connecting piece is provided, the beneficial effect who has is: the strength of the connecting plate body is higher through the convex edges on the two sides of the connecting plate body, the thickness of the steel plate can be effectively reduced, the consumption is reduced, and the production process is simpler through integrated forming.
