Embodiment 1

[0102] Such as figure 1 and 2 As shown, a kind of interlayer crane according to the present invention includes:

[0103] A fixed boom 1 arranged horizontally;

[0104] The mobile boom 2 is a rigid structural member;

[0105] The electric push rod 6 is connected with the movable arm frame 2 and the fixed arm frame 1 respectively, and the electric push rod 6 drives the movable arm frame 2 to reciprocate along the length direction of the fixed arm frame 1;

[0106] The reversing assembly 4 is used for reversing the hoisting wire rope 52 and is arranged at the front end of the mobile jib 2;

[0107] The hook assembly 3 is used to connect the suspended object and is arranged below the reversing assembly 4;

[0108] The hoisting mechanism 5 is arranged at the rear end of the mobile boom 2, and the hoisting wire rope 52 on the hoisting mechanism 5 is connected to the hook assembly 3 after being changed direction by the reversing assembly 4 , the lifting mechanism 5 drives the li...

Embodiment 2

[0122] Such as figure 1 and 2 As shown, a kind of interstory crane as described in Embodiment 1 is different from Embodiment 1 in that the bracket 8 used to support the fixed arm frame 1, the bracket 8 and the fixed arm frame 1 detachably connected, the bracket 8 comprises,

[0123] The vertically arranged front bracket 81 is detachably connected to the middle part of the fixed arm frame 1;

[0124] The vertically arranged rear bracket 82 is detachably connected to the rear end of the fixed arm frame 1 and is spaced apart from the front bracket 81 .

[0125] The fixed arm frame 1 is supported by the front bracket 81 and the rear bracket 82 arranged at vertical intervals. Compared with the single-supported crane, the wireless control crane support between the layers of the present application is more stable. At the same time, the front bracket 81 and the rear bracket 82 are detachably connected with the fixed arm frame 1 to facilitate the installation of the bracket 8. At t...

Embodiment 3

[0136] Such as figure 1 and 2 As shown, a kind of interstory crane as described in Embodiment 1 or 2, the difference between this embodiment and Embodiment 1 or 2 is that the fixed arm frame 1 is provided with a vertically arranged support rod 15 , the top of the support rod 15 is provided with a vertically arranged rope pulley 151, and a stay rope 152 is placed on the rope pulley 151. The stay rope 152, the two ends of the stay rope 152 are respectively fixed with the Both ends of the boom 1 are connected.

[0137] The part of the fixed arm frame 1 described in the present application that stretches out from the front bracket 81 is the cantilever end, which bears the downward gravity of the suspended object, and the front and rear ends of the fixed arm frame 1 are connected by a stay rope 152. The rear end applies an oblique upward pulling force to the front end of the fixed arm frame 1, and the vertical upward component of the pulling force can offset at least a part of th...

Abstract

The invention relates to a crane, in particular to an interlayer crane. The interlayer crane comprises a horizontally-arranged fixed cantilever frame, a moving cantilever frame, a reserving assembly,a lifting hook assembly, a hoisting mechanism and an electric push rod, wherein the moving cantilever frame is a rigid structural part, the reserving assembly is arranged at the front end of the moving cantilever frame, the lifting hook assembly is arranged on the lower part of the reserving assembly, the hoisting mechanism drives the lifting hook assembly to rise and fall by taking up and payingoff a hoisting steel wire rope, the electric push rod drives the moving cantilever frame to move in a reciprocating mode in the length direction of the fixed cantilever frame, and the moving cantilever frame and the hoisting mechanism are slidably connected with the fixed cantilever frame in the length direction of the fixed cantilever frame. According to the interlayer crane, the height of a hoisted object is finely adjusted through the hoisting mechanism, the electric push rod drives the moving cantilever frame to finely adjust the horizontal position of the hoisted object, the height position of the hoisted object is not affected when the horizontal position of the hoisted object is finely adjusted, thus fine adjusting of a curtain wall skeleton can be achieved very simply so as to lower the fine-adjusting cost, and meanwhile, potential safety hazards of installation personnel are lowered.

Description

technical field [0001] The invention relates to a crane, in particular to an interlayer crane. Background technique [0002] In the construction of building exterior wall decoration, it is often necessary to directly hoist the curtain wall skeleton (less than 500kg) to the installation location, and install it by the installer. [0003] At present, rails and single-arm cranes or tower cranes are mostly used for hoisting. However, when using rails and single-arm cranes for hoisting, it is inconvenient to install and dismantle, and it cannot be moved flexibly, and cannot adapt to the hoisting of various unit curtain wall frames. The use is limited and the cost is high. When the existing tower crane on site is used for hoisting, there are disadvantages of high hoisting cost and low efficiency. [0004] In order to solve the above problems, a unit curtain wall skeleton hoisting trolley has appeared in the field, such as the patent number: CN201410475777.3, a unit curtain wall ...
