Description

Technical Field

[0001] This utility model relates to the technical field of wire rope arrangement equipment, specifically to an automatic rope arranger for oil scooping truck drums. Background Technology

[0002] In oil well recovery operations, the oil recovery truck is a key piece of equipment, and its operational efficiency and accuracy directly affect the safety and efficiency of the operation. However, currently, the wire rope arrangement process on the oil recovery truck mainly relies on manual operation and visual judgment, which has many shortcomings. Specifically, the rope arrangement component achieves reciprocating movement through steering wheel rotation and chain drive. During this process, because it relies entirely on manual judgment, and the arrangement of the wire rope on the drum is affected by various factors, such as the weight of the downhole wire rope and the retrieval fluid, and the descent speed of the wire rope, these factors all lead to randomness and unevenness in the wire rope arrangement.

[0003] Uneven wire rope arrangement not only affects its service life but can also cause biting due to excessive local stress, further accelerating wear and damage. Furthermore, the separate operation of raising and lowering the wire rope and arranging it on the oil retrieval truck, while ensuring some focus, also introduces coordination problems and communication barriers. This is especially true in front-mounted oil retrieval trucks, where operators must operate the rope arranger at the confined rear end. This not only increases the difficulty of operation but also reduces observation efficiency due to oil contamination and the inertia of the high-speed wire rope, significantly diminishing the wire rope's utilization efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic rope arranger for oil scooping truck drums, thereby changing the problem that the arrangement of steel wire ropes in oil scooping trucks relies on manual experience, which leads to uneven arrangement, uneven stress, and affects the service life of the steel wire ropes.

[0005] To achieve the above objectives, this application proposes an automatic rope unwinding device for oil scooping truck drums, comprising:

[0006] The limit switch is installed on the drive rod of the oil scooping truck;

[0007] The controller, electrically connected to the limit switch, is used to receive limit signals;

[0008] The motor, electrically connected to the controller, is used to receive steering signals;

[0009] A clutch has a clutch input wheel and a clutch output wheel, wherein the clutch input wheel is connected to the output shaft of the motor via a drive chain;

[0010] The handwheel drive wheel is connected to the clutch output wheel via a driven drive chain.

[0011] In one embodiment, the handwheel drive wheel is sleeved on a rotating shaft, the end of which is connected to a steering wheel.

[0012] In one embodiment, the rotating shaft passes through a baffle and is connected to a slider via a sprocket assembly and a chain. The slider is fitted onto the transmission rod of the oil scooping vehicle. A limiter is provided on the slider, and a wire rope passes through the limiter and is wound around the drum of the oil scooping vehicle.

[0013] In one embodiment, the motor drives the driven transmission chain via a clutch to rotate into the handwheel drive wheel to achieve transmission, and the handwheel drive wheel then drives the slider to move via a chain.

[0014] In one embodiment, the slider moves on the drive rod of the oil scooping vehicle and sends a limit signal to the controller when it touches the limit switch, and the controller controls the motor to reverse.

[0015] In one embodiment, the clutch further includes a clutch lever that engages the clutch input wheel shaft with the clutch output wheel shaft when the clutch lever is pushed forward, and disengages the clutch input wheel shaft from the clutch output wheel shaft when the clutch lever is pushed back.

[0016] In one embodiment, the steel cable wheel speed converter of the oil scooping truck is equipped with a wheel speed converter, which is electrically connected to the controller. The controller converts the wheel speed electrical signal into a frequency signal and transmits it to the speed control switch of the motor.

[0017] In one embodiment, the speed control switch of the motor is a two-level speed control switch.

[0018] In one embodiment, the limiter includes two cylindrical rollers with a wire rope passing between them.

[0019] In one embodiment, the baffle has an observation window.

[0020] The advantages of the above technical solution adopted in this utility model compared with the prior art are:

[0021] 1. This application utilizes a limit switch to achieve the turning of the wire rope at its extreme positions, thus avoiding equipment damage caused by over-winding or slack.

[0022] 2. A dual-level speed control switch is adopted to achieve rapid matching of different locomotive drum sizes.

[0023] 3. By employing a clutch, the left and right movement of the rope guide during the lowering of the wire rope will not reverse and drag the motor, thus extending the service life of the motor.

[0024] 4. Chain drive is used to ensure the independence of each component and to enable rapid matching and maintenance of each component.

[0025] 5. The steering wheel and handwheel drive wheel are retained to facilitate on-site manual operation during maintenance or in case of motor failure.

[0026] 6. This application ensures that the wire ropes are arranged neatly and orderly, thereby extending their service life, and realizes the automatic operation of the wire rope arrangement of the oil scooping truck. Attached Figure Description

[0034] Please see Figure 1 This embodiment provides an automatic rope unwinding device for oil scooping truck drums, including:

[0035] A limit switch is installed on the transmission rod of the oil scooping vehicle. When the slider reaches the set limit position, the limit switch will send a limit signal to the controller. Preferably, the limit switch can be two cylindrical rollers, and the wire rope passes between the cylindrical rollers.

[0036] The controller is electrically connected to the limit switch. After receiving the limit signal, it will issue a direction command to make the stepper motor rotate forward or reverse.

[0037] The motor is electrically connected to the controller to receive steering signals. Preferably, the motor is equipped with a dual-level speed control switch. By adjusting the speed control switch, the motor speed can be precisely controlled to meet the speed matching requirements of different locomotive drums. This design improves the flexibility and adaptability of the rope arranger, enabling it to be more widely used in different types of locomotives and drum equipment.

[0038] A clutch has a clutch input wheel and a clutch output wheel, wherein the clutch input wheel is connected to the output shaft of the motor via a drive chain;

[0039] The handwheel drive wheel is connected to the clutch output wheel via a driven drive chain;

[0040] It should be noted that the handwheel drive wheel is sleeved on the rotating shaft, and the end of the rotating shaft is connected to the steering wheel, which is an existing structure; the rotating shaft passes through the baffle and is connected to the slider through the sprocket assembly and chain, and the slider is sleeved on the transmission rod of the oil scooping vehicle. A limiter is provided on the slider, and the wire rope passes through the limiter and is wound around the drum of the oil scooping vehicle; retaining the steering wheel and handwheel drive wheel can facilitate manual intervention and operation by maintenance personnel on site.

[0041] This application utilizes chain drive, which offers advantages such as simple structure, reliable transmission, and convenient maintenance. Chain drive ensures the independence of each component, allowing for quick matching and replacement. This improves the maintainability and flexibility of the automatic rope arranger and saves maintenance time.

[0042] When the wire rope is lowered, the limit switch is affected by the reciprocating motion of the wire rope, which passively drives the steering wheel and handwheel drive wheel to rotate. At the same time, the power is transmitted back to the motor through the driven and driven drive chains, causing damage to the motor. Therefore, before lowering the wire rope, the clutch lever on the clutch should be pushed back to disengage the clutch input wheel shaft from the clutch output wheel shaft, preventing damage to the motor caused by the swinging of the wire rope.

[0043] During operation, the rotational speed is converted into an electrical signal by the speed converter on the steel wire rope wheel of the oil scooping truck. This signal is then transmitted to the controller, which converts it into a corresponding frequency signal and outputs it to the motor's speed control switch, matching the motor's speed with the drum's speed. When the slider moves along the transmission rod of the oil scooping truck and touches the limit switch, it sends a limit signal to the controller, which then controls the motor to reverse. The motor drives the driven transmission chain via a clutch to rotate into the handwheel transmission wheel, which in turn drives the slider via a chain to move it. During this movement, the limit switch assists the steel wire rope to be evenly distributed on the drum.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
