Abstract
The utility model relates to a tower-hoist load-carrying safety apparatus, which comprises a bed, a lower spinner, a pylon, a rotation shaft sleeve, a top stand, a draw bar, an upper spinner, a tension rod and an arm. The bed is provided with the lower spinner. The pylon is arranged on the upper portion of the lower spinner. The upper spinner is arranged on the upper portion of the pylon. The rotation shaft sleeve is arranged between the lower spinner and the upper spinner. The arm is connected with the upper portion of the top stand. The lower spinner is connected with the lower portion of the top stand. The top stand is connected with the rotation shaft sleeve though the draw bar. A tension rod is arranged on the arm. The utility model can effectively solve potential safety hazards of present tower hoists, and has the advantages of good safety effect, low manufacturing cost and convenient installation and maintenance.
Description
Technical field
The utility model relates to a kind of load-carrying safety device, is specifically related to a kind of tower crane load-carrying safety device.
Background technology
At present, in lifting appliance commonly used, tower crane is a kind of important lifting appliance, and it has characteristics such as floor area is few, the lifting radian is big, delivery is convenient.But present tower crane device has great defective, and the head end of lifting and tail end load carrying ability have a long way to go, in order to enhance productivity, have to establish multistage lifting loading point, every section load carrying ability gradually reduces, if operation reconnaissance error is easy to cause safety misadventure, causes great loss.
Summary of the invention
The purpose of this utility model is to provide the tower crane load-carrying that a kind of safe effect is good, simple in structure, productive costs is low, easy to installation and maintenance safety device.
The technical scheme that the utility model adopted is: tower crane load-carrying safety device comprises pedestal, following spinner, king-post, shaft sleeve, fore-set, pitman, goes up spinner, pull bar and arm.Spinner is installed down on the pedestal, there is king-post following spinner top, the king-post top is equipped with spinner, between following spinner and the last spinner shaft sleeve is installed, the fore-set upper end links to each other with arm, the fore-set lower end links to each other with following spinner, and fore-set links to each other by pitman with shaft sleeve, and pull bar is installed on the arm.
During use, spinner in the startup drives spinner rotation down synchronously by shaft sleeve, drives by pitman then and withstands rotation, rotates at any angle thereby drive arm, finishes lifting and unloads thing work.As a whole owing to last spinner, shaft sleeve, following spinner, fore-set and arm are connected into, so just can be transported to the weight that head end is sling tail end always, solved the potential safety hazard of branch load-carrying lifting.
The utlity model has following advantage: can solve the potential safety hazard that existing tower crane exists effectively, safe effect is good, and is simple in structure, and productive costs is low, and is easy to installation and maintenance.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
Fig. 1 structural representation of the present utility model
In Fig. 1, (1), pedestal (2), time spinner (3), king-post (4), shaft sleeve (5), fore-set (6), pitman (7), last spinner (8), pull bar (9), arm
The specific embodiment
As shown in Figure 1, tower crane load-carrying safety device comprises pedestal (1), following spinner (2), king-post (3), shaft sleeve (4), fore-set (5), pitman (6), goes up spinner (7), pull bar (8) and arm (9).Spinner (2) is installed down on the pedestal (1), there is king-post (3) following spinner (2) top, king-post (3) top is equipped with spinner (7), between following spinner (2) and the last spinner (7) shaft sleeve (4) is installed, fore-set (5) upper end links to each other with arm (9), fore-set (5) lower end links to each other with following spinner (2), and fore-set (5) links to each other by pitman (6) with shaft sleeve (4), and pull bar (8) is installed on the arm (9).This device can solve the potential safety hazard that existing tower crane exists effectively, and safe effect is good, and productive costs is low, and is easy to installation and maintenance.
