Description

Technical Field

[0001] The utility model relates to the technical field of elevator transportation operations, in particular to a ground fixing structure of an elevator. Background Art

[0002] There are two types of elevators: fixed and mobile. When curing building panels, elevators are often used to lift the panels to a specified height and then send them into the curing room.

[0003] Among them, fixed lifts are fixed to the ground, with stable lifting, but limited working space. Mobile lifts generally use rollers to move on guide rails, but the roller method can easily cause the lift to deviate from the predetermined position.

[0004] Therefore, the applicant has designed a ground fixing structure for an elevator to assist in fixing the movable elevator at a predetermined position. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a ground fixing structure of an elevator.

[0006] The technical solution of this utility model is as follows:

[0007] A ground fixing structure for an elevator, installed below a base frame of the elevator, comprises:

[0008] A fixed seat, fixed on the ground;

[0009] The clamping unit comprises a first mounting seat fixed below the base frame, and an active clamping block and a passive clamping block are respectively hinged at the front and rear ends below the first mounting seat;

[0010] One end of the active clamping block is slidably connected to the passive clamping block through a rotating shaft, and the other end is hinged with a power unit at the rear and connected to an extrusion block at the front;

[0011] A sliding groove is provided at the connecting end of the passive clamping block and the active clamping block, and the other end is connected to the extrusion block;

[0012] The active clamping block and the passive clamping block are driven by the power unit to clamp the fixing seat or move away from the fixing seat, and the highest ground distance when away from the fixing seat is greater than the height of the fixing seat.

[0013] Through the movable active clamps and passive clamps, when the elevator moves along the track, the two clamps open to both sides to cross the fixed seat. When the elevator reaches the predetermined position, the two clamps tighten inwards and are respectively squeezed on both sides of the fixed seat, so that the elevator is fixed and will not shake.

[0014] Moreover, by means of sliding connection between the active clamping block and the passive clamping block, the action can be completed by only one power unit, thus simplifying the overall structure.

[0015] Regarding the specific structure of the fixing seat, the fixing seat includes a lower base plate and an upper boss, and the extrusion block can be extruded on the side of the upper boss.

[0016] The upper boss is a rectangular block.

[0017] The extrusion block is embedded in the lower ends of the active clamping block and the passive clamping block, and the outer surface is a plane, which can be fitted together with the side surface of the upper boss.

[0018] A plurality of slide grooves are arranged on the lower bottom plate and connected to the ground by bolts.

[0019] As for the power unit part, it comprises a second mounting seat fixed below the base frame and a telescopic cylinder hinged at its lower part, and the telescopic cylinder is hinged to the active clamping block.

[0020] As one of the implementation modes, the active clamp and the passive clamp are sickle-shaped structures. The active clamp is rotatably connected to the rear side below the first mounting seat through a shaft sleeve. There are two active clamps in number, and the telescopic cylinder is rotatably connected to the middle of the rear of the two active clamps through a rotating shaft.

[0021] The passive clamping block is rotatably connected to the front side below the first mounting seat through a shaft sleeve, and the rear sliding groove is connected to the middle of the front parts of the two active clamping blocks through a rotating shaft.

[0022] The width of the extrusion block is greater than that of the upper boss, which can increase the contact area between the two, ensure uniform force, and avoid excessive local force that affects service life and safety of use.

[0023] Through the above design, the ground fixing structure of the elevator of the utility model can realize that when the elevator moves along the track, the two clamps open to both sides through the movable active clamps and passive clamps to cross the fixed seat. When the elevator reaches the predetermined position, the two clamps tighten inwardly and are respectively squeezed on both sides of the fixed seat, so that the elevator is fixed and will not shake, effectively solving the problem of difficult positioning of movable elevators.
