Abstract
The utility model discloses a movable rotary hoist for eaves-hung cast-in-place concrete crash barrier of a bridge with eaves. The hoist comprises a traversing crane (1), a hanging bracket (2), a guy cable (3) and a hoisting machine (4), wherein the hanging bracket (2) is in rotational connection with the traversing crane (1) through a rotating shaft (5), the hanging bracket (2) is provided with a horizontal working table (2a), a rotary supporting wheel (2d) is arranged at the lower end of the horizontal working table (2a), the hoisting machine (4) is arranged and a balancing weight (6) is arranged at the rear end of the horizontal working table (2a), the hanging end of the guy cable (3) is hung in the air after the bypassing a pulley (2b) at the top end of the hanging bracket (2), and the rear end of the guy cable (3) is connected with a power end of the hoisting machine (4). The movable rotary hoist has the advantages of simple structure, convenient construction and low manufacturing cost, and can guarantee the safety and greatly quicken the construction speed at the same time.
Description
Technical field
The utility model belongs to the bridge construction equipment technical field, concretely, relates to a kind of movable type rotation loop wheel machine that the bridge band is hung eaves Cast-in-place concrete anticollision barrier that is used for.
Background technology
Domestic present concrete anticollision barrier design is broadly divided into 3 kinds by profile mode difference, and be respectively: common sitting posture anticollision barrier, band are hung cast-in-place anticollision barrier of eaves and prefabricated installation link plate anticollision barrier.
| The guardrail type | Advantage | Shortcoming |
| General expression Cast-in-place concrete anticollision barrier | Construction is simple, and most of unit in charge of construction is this construction technology on top of. | Outward appearance is linear poor, and the easy cross flow of rainwater influences beam body durability to the beam body |
| Band is hung eaves Cast-in-place concrete anticollision barrier | Linear smoothness, attractive in appearance can prevent effectively that rainwater from flowing backward to the beam body.Whole structure is good | Difficulty of construction is big, no matching operation facility, and a lot of units in charge of construction are not contacted. |
| Prefabricated installation link plate anticollision barrier | Linear comparatively smooth, attractive in appearance, difficulty of construction is general. | The welded and installed mass discrepancy is big, and whole impression effect is general.If workman's welded and installed poor quality easily buries potential safety hazard. |
Along with the day by day raising of people to esthetic requirement, the common sitting posture anticollision barrier of former routine can not satisfy the aesthetic needs of people day by day.The concrete anticollision barrier that welded and installed band link plate or direct cast-in-place band are hung eaves arises at the historic moment.
The construction of band extension eaves Cast-in-place concrete anticollision barrier is the ripe construction outfitting tool of none cover still, and most units in charge of construction all adopt small crane organizing construction, have the shortcoming that the plant equipment expense has high input, the safety nothing ensures.
The utility model content
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and is used to install Bridge guardrail band link plate or cast-in-place band and hangs the movable type rotation loop wheel machine that the bridge band of eaves is hung eaves Cast-in-place concrete anticollision barrier.
The technical solution of the utility model is as follows:
Be used for the bridge band and hang the movable type rotation loop wheel machine of eaves Cast-in-place concrete anticollision barrier, this loop wheel machine comprises travelling car, suspension bracket, drag-line and hoist engine, be rotationally connected by rotating shaft between described suspension bracket and the travelling car, described suspension bracket has horizontal table, this horizontal table lower end is provided with the rotational support wheel, described horizontal table rear end is provided with described hoist engine and is placed with balancing weight, and it is unsettled that described drag-line hanging end is walked around the pulley on described suspension bracket top, and the rear end links to each other with the power end of described hoist engine.
Utilization utilizes the movable type 360 degree rotation loop wheel machines installations and the stripping of said structure used.This facility design crane capacity 250kg.The template lifting utilizes hoist engine control; 360 degree rotations utilize Artificial Control.Processing cost is low, flexible and convenient operation, and speed of application is fast, and safety is guaranteed.
Described suspension bracket middle part is provided with the transition pulley.
Beneficial effect: the utility model is simple in structure, easy construction, low cost of manufacture, accelerates speed of application when can guarantee safety greatly.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, 2: be used for the movable type rotation loop wheel machine that the bridge band is hung eaves Cast-in-place concrete anticollision barrier, this loop wheel machine comprises travelling car 1, suspension bracket 2, drag-line 3 and hoist engine 4, be rotationally connected by rotating shaft 5 between described suspension bracket 2 and the travelling car 1, described suspension bracket 2 has horizontal table 2a, this horizontal table 2a lower end is provided with rotational support wheel 2d, described horizontal table 2a rear end is provided with described hoist engine 4 and is placed with balancing weight 6, it is unsettled that described drag-line 3 hanging ends are walked around the pulley 2b on described suspension bracket 2 tops, and the rear end links to each other with the power end of described hoist engine 4.Described suspension bracket 2 middle parts are provided with transition pulley 2c.
The practical approach of this programme is: at first lay two channel-section steels and do to advance or retreat the walking track on bridge floor 7, employing manually will be rotated loop wheel machine and be pushed on the walking track, trundle moves along track, the purpose that track is set is to have a large amount of reinforcing bar projectioies in the men working ahead process, and dolly directly moves and can be hindered.Manually will rotate the template position of hanging that loop wheel machine turns to crash barrier 8 then, the control hoist engine puts down suspension hook and template is caught on and slings, and then utilizes the artificial rotation institute template of hanging to the installation site, by the height that the button control template promotes or descends, be convenient to workman's fitting operation.
Claims (2)
1. be used for the bridge band and hang the movable type rotation loop wheel machine of eaves Cast-in-place concrete anticollision barrier, it is characterized in that: this loop wheel machine comprises travelling car (1), suspension bracket (2), drag-line (3) and hoist engine (4), be rotationally connected by rotating shaft (5) between described suspension bracket (2) and the travelling car (1), described suspension bracket (2) has horizontal table (2a), this horizontal table (2a) lower end is provided with rotational support wheel (2d), described horizontal table (2a) rear end is provided with described hoist engine (4) and is placed with balancing weight (6), it is unsettled that described drag-line (3) hanging end is walked around the pulley (2b) on described suspension bracket (2) top, and the rear end links to each other with the power end of described hoist engine (4).
