Problems solved by technology

[0007] Although this new type of electric hoist can lock the heavy objects hanging on the hook to improve the safety of use; when the operation stops, it can also buffer the shell to improve the stability of use, but the connection between the electric hoist and the sliding seat is not firm enough , and the two are fixed by multiple bolts. After a long time of use, the bolts are prone to deformation, which brings difficulties to later maintenance and disassembly.

Embodiment 1

[0031]An electric hoist provided in this embodiment has a structure such asFigure 1-3As shown, it includes a shell 1, a truss 21, and a sliding seat 2 for connecting the shell 1 and the truss 21. The top of the shell 1 is provided with a connecting mechanism 3 at a position corresponding to the sliding seat 2, and the sliding seat 2 is provided with The cavity 22 of the connecting mechanism 3 includes a plurality of clamping blocks 31 slidingly connected to the top of the housing 1.

[0032]The clamping block 31 is in a bent shape, the cavity 22 is provided with a clamping slot 23 for accommodating the clamping block 31, and the connecting mechanism 3 includes a driving member for pushing a plurality of clamping blocks 31 into or out of the clamping slot 23 synchronously 4, and a locking member 5 for locking the driving member 4 and the clamping block 31 to determine the relative position of the two. The housing 1 is also provided with an auxiliary connecting member 6 for assisting in ...

Embodiment 2

[0036]An electric hoist, such asFigure 4 As shown, the difference from Embodiment 1 is that the top of the housing 1 is rotatably connected with an active disc 43 through a rotating shaft 46, and the housing 1 at the bottom of the active disc 43 is fixed with a fixed disc 44 coaxially arranged with it, and is clamped. The block 31 and the sliding block 32 are integrally connected by a push rod 33, the push rod 33 penetrates the driven disk, and the sliding groove 11 is provided on the fixed disk 44.

[0037]The driving disc 43 is provided with an arc-shaped pushing groove 45, the width of the pushing groove 45 is the same as the diameter of the pushing rod 33, the pushing groove 45 is arranged corresponding to the sliding groove 11, and the clamping block 31, the pushing groove 45, and the clamping groove 23 The sliding groove 11 and the sliding groove 11 are both provided with four groups around the central axis of the driving disc 43.

[0038]The locking member 5 includes a locking worm...

Abstract

The invention discloses an electric hoist, and relates to the technical field of hoisting equipment. The electric hoist comprises a shell, a truss and a sliding seat for being connected with the shelland the truss; a connection mechanism is arranged in the position, corresponding to the sliding seat, of the top of the shell, and the sliding seat is internally provided with a cavity for containingthe connection mechanism; the connection mechanism comprises a plurality of clamping blocks which are slidably connected to the top of the shell, the clamping blocks are in a bent shape, and the cavity is internally provided with clamping grooves for containing the clamping blocks; the connection mechanism further comprises a driving piece for driving the multiple clamping blocks to be synchronously clamped into or separated from the clamping grooves, and a locking piece which is used for locking the driving piece and the clamping blocks so that the relative positions of the locking piece andthe clamping blocks can be determined; and the shell is further provided with an auxiliary connection piece for assisting the sliding seat and the shell being fixed. According to the electric hoist,an electric hoist body and the sliding seat can be firmly connected conveniently, the connection structures are close, deformation caused by bolt connection can be avoided, and the difficulty of follow-up maintaining and disassembling work is low.

Description

Technical field[0001]The invention relates to the technical field of lifting equipment, in particular to an electric hoist.Background technique[0002]Electric hoist is a kind of special lifting equipment, which is installed on overhead cranes and gantry cranes. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places.[0003]The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length, large width, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low voltage control to increase the safety of the cont...
