Abstract
The utility model discloses a multipurpose lifting pulley, which comprises two pulley mounting clamping plates, wherein a first pulley is arranged at one end between the two pulley mounting clamping plates; a lifting hook is arranged at the other end between the two pulley mounting clamping plates; a multipurpose inserted fixing piece is fixedly arranged on one side of the two pulley mounting clamping plates; and an insertion head in the multipurpose insertion fixing piece is a stepped pipe or a stepped column. The conventional single mode that the pulley and a chord and an iron tower are connected through the lifting hook is changed; and because all antennas and accessory equipment on the iron tower are arranged on a steel pipe, the pulley has multiple connection modes, so that the pulley can be lifted and inserted, is suitable for pipes with different diameters and is conveniently mounted; and meanwhile, the pulley can rotate for meeting the operating requirements, the high-altitude construction safety is improved, and simultaneously the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of lifting device, specifically refers to be used for mobile communication iron tower, the lifting construction of equipment such as antenna, feeder line, R04, the outdoor lightning protection box of direct current, antenna bracket and a kind of Hoisting tackle that daily attention must be used.
Background technology
At present; The lifting construction and the daily attention of equipment such as the antenna that on the mobile communication iron tower, uses, feeder line, R04, the outdoor lightning protection box of direct current, antenna bracket are all accomplished by coaster; This coaster comprises two pulleys installation clamping plate; An end of installing between the clamping plate at two pulleys is equipped with a pulley, and the other end is equipped with a suspension hook.This coaster normally is mounted on the crossbeam of iron tower through suspension hook; Or be strapped on the vertical steel pipe of iron tower through lasso trick, particularly for the latter, coaster tied up vertically make coaster loosening easily on the steel pipe; Bondage is not firm, and it is not only unreliable but also dangerous therefore to cause coaster to use.
Summary of the invention
The utility model purpose is to solve the problem that existing coaster can't failure-free be installed and used on vertical steel pipe, and a kind of Hoisting tackle of using is provided more.
The Hoisting tackles of using that the utility model provides more; Comprise two pulleys installation clamping plate; An end of installing between the clamping plate at two pulleys is equipped with a pulley, and the other end is equipped with a suspension hook, and a side of clamping plate being installed at two pulleys is installed with uses the grafting connecting element more one.
Describedly many comprise the fixed block of stepped connection-peg and connection-peg end with the grafting connecting element, fixed block is fixedly mounted between two pulleys installation clamping plate.
Described how being fixed by bolts between two pulleys installation clamping plate through the fixed block of end and the fixed installation hole on the fixed block with the grafting connecting element, perhaps the fixed block through the end is weldingly fixed between two pulleys installation clamping plate.
Connection-peg in described many use grafting connecting elements is stepped body or stepped cylinder.
Advantage of the utility model and good effect:
The utility model has changed the single connection mode of leaning on suspension hook and lasso trick and iron tower of former coaster.Because all antennas and attendant equipment all are mounted on the steel pipe on the iron tower; Therefore change coaster into multiple connection mode; Make it to hang, also can plug the tubing that is fit to multiple different-diameter simultaneously, make things convenient for coaster to install, coaster also can rotate with requirements of one's work simultaneously; Improve the safety of high-altitude construction operation, also improved work efficiency simultaneously.
Description of drawings
Fig. 1 is the Hoisting tackle structural representations of using more;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is many with grafting anchor structure scheme drawing;
Fig. 4 is the left view of Fig. 3.
Among the figure, 1 suspension hook, 2 pulleys are installed clamping plate, 3 pulley backplates, 4 pulleys are used the grafting connecting element more 5, the 5-1 connection-peg, the 5-2 fixed block, 5-3 fixedly mounts the hole.
The specific embodiment
Embodiment 1:
As illustrated in fig. 1 and 2; The Hoisting tackles of using that the utility model provides more; Comprise two pulleys installation clamping plate 2; An end of installing between the clamping plate at two pulleys is equipped with a pulley 4 through pulley backplate 3, and the other end is equipped with a suspension hook 1, and the side that clamping plate are installed at two pulleys is installed with more than one with grafting connecting element 5.
Like Fig. 3 and shown in Figure 4 many with grafting connecting element 5; Should be many comprise how being fixed by bolts to the fixed block 5-2 of stepped connection-peg 5-1 and connection-peg end two pulleys through the fixed block of end and the fixed installation hole 5-3 on the fixed block (perhaps the fixed block 5-2 through the end is weldingly fixed between two pulleys installation clamping plate 2) between the clamping plate 2 is installed with grafting connecting element 5 with grafting connecting element 5.
Described that to use the connection-peg in the grafting connecting element be stepped body or stepped cylinder is more, and for saving in material and alleviate the weight of coaster, connection-peg is preferably selected stepped body for use.The stepped body that connection-peg in this example becomes the steel pipe by large, medium and small three sections various outer diameters to constitute according to the internal diameter size design of steel pipe commonly used on the mobile communication iron tower at present; And in order to guarantee many intensity with the grafting connecting element, the steel pipe of three sections various outer diameters of the fixed block of connection-peg and end and connection-peg is all as a whole.
During use, how this is got final product with many insertion in the vertical steel pipe with the grafting connecting element on the Hoisting tackle.The use of suspension hook and pulley and former coaster use identical.
Claims (5)
1. use Hoisting tackle one kind more; Comprise two pulleys installation clamping plate; An end of installing between the clamping plate at two pulleys is equipped with a pulley, and the other end is equipped with a suspension hook, it is characterized in that being installed with in the side that two pulleys are installed clamping plate using the grafting connecting element one more.
2. according to claim 1ly many use Hoisting tackle, it is characterized in that describedly manyly comprising the fixed block of stepped connection-peg and connection-peg end with the grafting connecting element, fixed block is fixedly mounted between two pulleys installation clamping plate.
