Description
Technical field
The utility model relates to motor device field, particularly relates to a kind of power-assisted climbing-up device.
Background technology
In oil drilling and underground work process, staff usually needs upper and lower derrick to complete ongoing operations.For the labour intensity alleviating staff ensures the personal safety of staff simultaneously, derrick can be provided with climb-aiding device.
The climb-aiding device of prior art is generally counter weight type climb-aiding device, namely utilize balance weight body or the balancing weight of setting, pull balance weight body or balancing weight to provide pulling force upwards (general about 24KG) for staff up and down by wire rope and power needed for declining.But it should be noted that counter weight type climb-aiding device needs balance weight body to be pulled to derrick upper end when staff fulfils assignment lower derrick, to be the tractive force provided upwards that rises next time.And the balancing weight hanging on high-altitude also exists the accident potential that high-altitude junk is hurted sb.'s feelings, be unfavorable for the safety guarantee of work high above the ground.
Utility model content
The utility model provides a kind of power-assisted climbing-up device, and this power-assisted climbing-up device is simple to operate and need not arrange balancing weight thus for work high above the ground provides better safety guarantee.
For solving the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of power-assisted climbing-up device, is characterized in that, comprising:
Hydraulic Station, described Hydraulic Station is provided with hydraulic pump, variable-frequency motor, fuel tank, direction valve, choke valve, overflow valve;
Control the control cabinet of described Hydraulic Station;
Be controlled by the rope woolding drive unit of Hydraulic Station, described rope woolding drive unit is provided with the halliard of band hanging point;
And be installed on derrick top, wear fixed pulley group around halliard.
Further, the mechanical clutch of fall arrest is also provided with in described rope woolding drive unit.
Comparatively preferred, a remote control module is provided with in described control cabinet, described power-assisted climbing-up device includes a remote controller, and described remote control module regulates the operating frequency of variable-frequency motor in described Hydraulic Station with control cabinet described in remote control for the remote signal that receives described remote controller and send.
Comparatively preferred, the operating voltage of described variable-frequency motor is 380V.
Concrete, described power-assisted climbing-up device is climbed for the power-assisted of upper and lower oil field motor-pumped well.
A kind of power-assisted climbing-up device that the utility model provides, this power-assisted climbing-up device includes Hydraulic Station, control cabinet, is controlled by the rope woolding drive unit of Hydraulic Station and is installed on the fixed pulley group on derrick top.This power-assisted climbing-up device need not arrange balancing weight, thus solves the accident potential that prior art high-altitude junk hurts sb.'s feelings; This power-assisted climbing-up device also has feature simple to operate simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model power-assisted climbing-up device.
Detailed description of the invention
The utility model provides a kind of power-assisted climbing-up device, and this power-assisted climbing-up device is simple to operate and need not arrange balancing weight thus for work high above the ground provides better safety guarantee.
Below in conjunction with following accompanying drawing, the utility model embodiment is described in detail.
The utility model provides a kind of power-assisted climbing-up device, and as shown in Figure 1, this power-assisted climbing-up device comprises Hydraulic Station 1, concrete, includes hydraulic pump, variable-frequency motor, fuel tank, direction valve, choke valve, overflow valve etc. in this Hydraulic Station 1; For the control cabinet 2 at hydraulic control station 1; Rope woolding drive unit 3, wherein, rope woolding drive unit 3 is controlled by Hydraulic Station 1, includes the halliard of band hanging point; And be arranged on derrick top, wear fixed pulley group 4 around halliard.In addition, comparatively preferably, the mechanical clutch preventing worker fall is also provided with in rope woolding drive unit 3; Utilize this mechanical clutch, coordinate with traditional anti-falling device the dual fail-safe forming fall arrest.
It should be noted that, before the power-assisted climbing-up device using the present embodiment to provide, fixed pulley group should be installed on derrick top (or on derrick crown).Wherein, as one comparatively preferred embodiment, when derrick is provided with guardrail, for ensureing that halliard does not contact with guardrail, fixed pulley group should be stretched out along derrick cat ladder direction and is no less than 300mm; In addition, for guaranteeing the firm welding of fixed pulley group, fixed pulley group top stretching resistance should be not less than 400KG.
Further, as shown in Figure 1, power-assisted climbing-up device also includes a remote controller 5, and this remote controller 5 is corresponding with the remote control module in control cabinet to be arranged.Remote control module receives the remote signal that sends of remote controller, thus remote pilot case regulate the operating frequency of variable-frequency motor in Hydraulic Station.
Concrete, the process that is combined is further described the power-assisted climbing-up device that the utility model embodiment provides.Under the prerequisite installing fixed pulley group in advance, first staff arranges control cabinet, completes pulling force, the soaring isoparametric preliminary setting of speed; Then safety belt to hang on halliard and tightens jam nut by staff, prepares for rising; Then staff controls remote controller, sends climb command, and Hydraulic Station accepts control instruction and drives rope woolding drive unit to strain halliard, for staff provides pulling force upwards; And after arriving job position, staff handles remote controller and stops.Wherein, in uphill process, staff can utilize remote controller to control vertical motion according to reality impression, to be comfortablely advisable with self.Same, in decline process, staff is by having controlled down maneuver to the correspondence of remote controller, and be arranged on mechanical clutch in rope woolding drive unit can the brake hard when personnel fall, thus protect the safety of staff.
In addition, need to add is that, in Hydraulic Station, the working power of variable-frequency motor is preferably 380V.
A kind of power-assisted climbing-up device that the utility model provides, this power-assisted climbing-up device includes Hydraulic Station, control cabinet, is controlled by the rope woolding drive unit of Hydraulic Station and is installed on the fixed pulley group on derrick top.This power-assisted climbing-up device need not arrange balancing weight, thus solves the accident potential that prior art high-altitude junk hurts sb.'s feelings; This power-assisted climbing-up device also has feature simple to operate simultaneously.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
