Abstract

The utility model discloses a sinking winch which comprises a winding drum, an intermediate shaft device, a motor portion and a safety brake, wherein the intermediate shaft device is arranged on one side of the lower end of the winding drum, the upper end of the intermediate shaft device is provided with the motor portion, and the safety brake is arranged on one side of the upper end of the winding drum. The motor portion includes a motor, an elastic coupling, a speed reducer and a floating coupling, wherein the motor, the elastic coupling, the speed reducer and the floating coupling are connected in sequence, the floating coupling is connected with the intermediate shaft device, and the elastic coupling is provided with a working brake. The sinking winch is small in occupied space, convenient to operate, more suitable for being operated in a place of small space, reasonable in layout, compact in structure, low in noise, safe, reliable and easy to maintain, thereby creating good conditions for rapid construction of a vertical shaft.

Description

A kind of sinking winch

Technical field

The utility model relates to a kind of sinking winch.

Background technology

Sinking winch is the visual plant in the sinking shaft system construction, along with improving constantly of shaft construction Mechanization Level, large-scale jewel hole, muck, building the preparation of construction such as wall and sinking winch need to be in well, near derrick and well head, in the limited space such as ground, coordinate to arrange, meeting the sinking shaft system construction technique, construction safety, construction cost, operating efficiency, requiring under prerequisite of the aspect such as device structure and running, occupation area of equipment is promoted to the problem of a consideration, but be vertical layout in existing installation between all parts, make whole equipment occupation space larger, more difficult in single job, affect construction safety, job schedule and economic benefit.

The utility model content

The purpose of this utility model is exactly in order to address the above problem, a kind of sinking winch is provided, taking up room of it is smaller, operates more conveniently, is more suitable for the operation of less place, space, rationally distributed, compact conformation, noise is little, safe and reliable, be easy to safeguard, for Construction of Shaft has been created good condition.

To achieve these goals, the utility model adopts following technical scheme:

A kind of sinking winch comprises reel, the tween drive shaft device, and motor section, sure brake,

Reel lower end one side is established the tween drive shaft device, and motor section is established in tween drive shaft device upper end, and reel upper end one side is established sure brake.

Described motor section comprises electrical motor, elastic coupling, retarder, end-float coupling, and each parts connect successively, and end-float coupling is connected with the tween drive shaft device, establishes service brake on elastic coupling.

Described retarder is arranged in the end-float coupling upper end.

Described reducer input shaft is parallel with output shaft, and input shaft and output shaft are in the retarder both sides.

The beneficial effects of the utility model:

Taking up room of it is smaller, operates more conveniently, is more suitable for the operation of less place, space, rationally distributed, compact conformation, and noise is little, safe and reliable, is easy to safeguard, for Construction of Shaft has been created good condition.

The accompanying drawing explanation

Fig. 1 is that former sinking winch is arranged schematic diagram;

Fig. 2 is that the utility model sinking winch is arranged schematic diagram.

Wherein, 1. electrical motor, 2. elastic coupling, 3. service brake, 4. retarder, 5. end-float coupling, 6. tween drive shaft device, 7. reel, 8. sure brake.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

As Fig. 1, whole device takes up room larger in vertical distribution, and entire length is retarder 4, end-float coupling 5, reel 7, the length of these parts.

As Fig. 2, this improvement sinking winch schematic diagram,

The present embodiment comprises electrical motor 1, elastic coupling 2, service brake 3, retarder 4, end-float coupling 5, tween drive shaft device 6, reel 7, sure brake 8.

Electrical motor 1, elastic coupling 2, retarder 4, end-float coupling 5, tween drive shaft device 6, reel 7 connect successively; Electrical motor 1 take in work as engine installation, and electrical motor 1 drives retarder 4 motions through elastic coupling 2, and retarder 4 connects tween drive shaft device 6 through end-float coupling 5 and drives reel 7.

Service brake 3 is located on elastic coupling 2, and sure brake 8 is located at reel 7 left sides, upper end, and service brake 3, sure brake 8 are guaranteed the sinking winch security of system.

Described tween drive shaft device 6 is located at reel 7 left sides, lower end, and end-float coupling 5 is located at tween drive shaft device 6 tops.

Described retarder 4 is located at end-float coupling 5 tops.

Described retarder 4 input shafts are parallel with output shaft, and input shaft is located at retarder 4 upper ends, and output shaft is located at retarder 4 lower ends;

Adopt and be arranged in parallel as Fig. 2 the utility model is whole, take up room less, be applicable to little space and use, compact conformation.

Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
