Description

Technical Field

[0001] This utility model relates to an anti-loosening device for steel wire ropes of a ladder truck, belonging to the field of mechanical equipment technology. Background Technology

[0002] Composed of multiple telescopic or folding boom sections, it enables vertical extension and horizontal rotation, boasting a large extension length and high working height, raising the work platform or rescue equipment to the required height. The boom is generally made of high-strength metal materials and driven by a hydraulic system to ensure smooth and reliable extension and rotation. The work platform, located at the top of the ladder, provides operating space for workers and can support equipment, personnel, or rescue targets of a certain weight. The work platform may be equipped with safety devices, such as guardrails, to ensure operator safety. It may also include control devices allowing operators to fine-tune the ladder's movements from the platform.

[0003] Chinese patent CN212712643U discloses a device for preventing the loosening of wire ropes on aerial ladder trucks, comprising: a mounting base for mounting the device; a first protective structure disposed on the upper surface of the mounting base; a driving structure disposed on the first protective structure; a rotating structure disposed on the driving structure; a bearing structure disposed on the rotating structure; a second protective structure disposed on the first protective structure; and a third protective structure disposed on the first protective structure. This utility model relates to the field of preventing the loosening of wire ropes on aerial ladder trucks, is very convenient, reduces unnecessary trouble, has a relatively simple structure, and is easy to use.

[0004] However, because aerial ladder trucks are often in complex outdoor environments and operate continuously, the surface of the wire rope is prone to wear and loosening due to a lack of timely maintenance. Once the wire rope loosens, it not only affects the normal operation of the aerial ladder truck but may also cause serious safety accidents. Currently available anti-loosening devices are mostly complex in structure, have high maintenance costs, and are not ideal in preventing loosening, failing to effectively solve the problem of wire rope loosening caused by outdoor environmental factors. Therefore, a wire rope anti-loosening device for aerial ladder trucks is proposed.

[0005] To address this, a device for preventing the steel wire rope of a ladder truck from loosening is proposed. Utility Model Content

[0006] In view of this, the present invention provides a wire rope anti-loosening device for aerial ladder trucks to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A steel wire rope anti-loosening device for a ladder truck includes two side support frames that correspond to each other on the left and right sides. The two side support frames are installed on the ladder truck body. Winding rollers are symmetrically arranged on the upper and lower sides between the pair of side support frames. A rotating rigid rope is wound between the two winding rollers. An L-shaped support mounting frame is fixedly connected to the right end of the side support frame on the left side. An anti-loosening component is fixedly connected to the right end of the L-shaped support mounting frame, and the anti-loosening component is located outside the rotating rigid rope. The anti-loosening component includes a vertical outer sleeve. An inner oil storage hollow chamber is opened at the inner end of the vertical outer sleeve. The inner end of the inner oil storage hollow chamber is filled with lubricating liquid. One-way solenoid valves are fixedly connected to the left and right sides of the lower inner wall of the inner oil storage hollow chamber. Multiple elastic connectors are fixedly connected to the inner side wall of the vertical outer sleeve. An arc-shaped adjustable contact block is fixedly connected to the end of the multiple elastic connectors away from the vertical outer sleeve. Multiple electromagnetic heating inner rings are provided at the inner end of the inner oil storage hollow chamber.

[0008] More preferably, a conical bottom guide plate is fixedly connected to the lower end of the internal oil storage hollow compartment, and the conical bottom guide plate cooperates with a one-way solenoid valve.

[0009] More preferably, the upper end of the inner oil storage hollow chamber is provided with a top replenishment hole, and an electromagnetic heating inner ring is fixedly connected to the lower inner wall of the inner oil storage hollow chamber.

[0010] More preferably, the multiple arc-shaped adjustable contact blocks are arranged in a ring at equal intervals, and the end of the arc-shaped adjustable contact block away from the elastic connector is fixedly connected to multiple flexible protruding bristle inner layers.

[0011] More preferably, the rotating rigid rope passes through the inside and outside of the vertical outer sleeve, and the rotating rigid rope is in contact with the arc-shaped adjustable contact block. Multiple electromagnetic inner matching blocks are fixedly connected to the inner end of the vertical outer sleeve.

[0012] More preferably, multiple electromagnetic inner matching blocks are magnetically connected to corresponding arc-shaped adjustable contact blocks, and an external intelligent controller is fixedly connected to the right end of the vertical outer sleeve.

[0013] More preferably, the external intelligent controller is electrically connected to the electromagnetic inner matching block, the one-way solenoid valve, and the electromagnetic heating inner ring via wires.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. In this utility model, when the ladder truck starts operating, the rotating rigid rope begins to rotate under the drive of the winding roller. If the temperature is too low, the electromagnetic heating inner ring starts to work, heating the lubricating liquid and improving its fluidity. At the same time, the external intelligent controller controls the one-way solenoid valve to open. Under the guidance of gravity and the conical bottom guide plate, the lubricating liquid drips onto the surface of the rotating rigid rope through the one-way solenoid valve and the connected guide hose. As the rotating rigid rope continues to rotate, the lubricating liquid is evenly carried to its outer side, playing a lubricating role. During this process, the elastic connector automatically adjusts the contact pressure between the arc-shaped adjustable contact block and the rotating rigid rope according to the running state of the rotating rigid rope. The flexible protruding bristle inner layer at the end of the arc-shaped adjustable contact block contacts the rotating rigid rope, helping the lubricating liquid to more evenly blend with the surface of the rotating rigid rope and improve the lubrication effect.

[0016] II. In this utility model, when the aerial ladder truck stops operating, the external intelligent controller receives a stop signal and controls the electromagnetic inner matching block to generate magnetic force, magnetically attracting the arc-shaped adjustable contact block outward. This prevents the flexible protruding brush inner layer from making close contact with the surface of the rotating rigid rope, avoiding wear caused by prolonged static contact. Simultaneously, based on the lubricating liquid level information monitored by the liquid level sensor in the inner oil storage hollow chamber, if the liquid level is lower than the set value, the external intelligent controller will remind the operator to replenish the lubricating liquid in the inner oil storage hollow chamber through the top replenishment hole via indicator lights or remote signals. Through the coordinated work of various components, effective anti-loosening and automatic lubrication of the aerial ladder truck's wire rope are achieved. The external intelligent controller, as the control core, precisely regulates the operating status of each component, ensuring that the device can work stably and efficiently under different working conditions.

Detailed Implementation

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0026] like Figure 1-4 As shown, this utility model embodiment provides a wire rope anti-loosening device for a ladder truck, including two side support frames 1 that correspond to each other on the left and right sides. The two side support frames 1 are installed on the ladder truck body. Winding rollers 2 are symmetrically arranged on the upper and lower sides between the pair of side support frames 1. A rotating rigid rope 3 is wound between the two winding rollers 2. An L-shaped support mounting frame 5 is fixedly connected to the right end of the left side support frame 1. An anti-loosening component 4 is fixedly connected to the right end of the L-shaped support mounting frame 5, and the anti-loosening component 4 is located outside the rotating rigid rope 3. The anti-loosening component 4 includes a vertical outer sleeve 6, an inner oil storage hollow chamber 8 is provided at the inner end of the vertical outer sleeve 6, the inner end of the inner oil storage hollow chamber 8 is filled with lubricating liquid 16, one-way solenoid valves 9 are fixedly connected to the left and right sides of the lower inner wall of the inner oil storage hollow chamber 8, multiple elastic connectors 11 are fixedly connected to the inner side wall of the vertical outer sleeve 6, an arc-shaped adjustable contact block 12 is fixedly connected to the end of the multiple elastic connectors 11 away from the vertical outer sleeve 6, and multiple electromagnetic heating inner rings 17 are provided at the inner end of the inner oil storage hollow chamber 8.

[0027] A conical bottom guide plate 10 is fixedly connected to the lower end of the inner oil storage hollow chamber 8, and the conical bottom guide plate 10 cooperates with the one-way solenoid valve 9. A top replenishment hole 7 is opened at the upper end of the inner oil storage hollow chamber 8. An electromagnetic heating inner ring 17 is fixedly connected to the lower inner wall of the inner oil storage hollow chamber 8, and multiple arc-shaped adjustable contact blocks 12 are arranged in a ring at equal intervals. Multiple flexible protruding brush inner layers 14 are fixedly connected to the end of the arc-shaped adjustable contact block 12 away from the elastic connector 11. The rotating rigid rope 3 passes through the inside and outside of the vertical outer sleeve 6, and the rotating rigid rope 3 is in contact with the arc-shaped adjustable contact block 12. Example

[0028] like Figure 1-4 As shown, in one embodiment, a plurality of electromagnetic inner matching blocks 13 are fixedly connected to the inner end of the vertical outer sleeve 6, and the plurality of electromagnetic inner matching blocks 13 are magnetically connected to the corresponding arc-shaped adjustable contact blocks 12. An external intelligent controller 15 is fixedly connected to the right end of the vertical outer sleeve 6. The external intelligent controller 15 is electrically connected to the electromagnetic inner matching blocks 13, the one-way solenoid valve 9, and the electromagnetic heating inner ring 17 through wires.

[0029] When the aerial ladder truck stops operating, the external intelligent controller 15 receives a stop signal and controls the electromagnetic inner matching block 13 to generate magnetic force, which magnetically attracts the arc-shaped adjustable contact block 12 outward, so that the flexible protruding bristle inner layer 14 does not come into close contact with the surface of the rotating rigid rope 3, thus avoiding wear caused by prolonged static contact between the two.

[0030] In operation, this utility model is as follows: During actual installation, the two side support frames 1 are fixed at their respective positions on the ladder truck. The winding roller shafts 2 are installed between the side support frames 1. The rotating rigid rope 3 is wound around the two winding roller shafts 2. The anti-loosening component 4 is fixed to the right end of the left support frame 1 by an L-shaped support mounting bracket 5, ensuring that it is located outside the rotating rigid rope 3. The winding roller shafts 2 are externally connected to a hydraulic system. When the ladder truck starts operating, the winding roller shafts 2, driven by the external hydraulic system, drive the rotating rigid rope 3 to begin rotating. If the temperature is too low, the electromagnetic heating inner ring 17 will start... During operation, the lubricating fluid 16 is heated to improve its fluidity. Simultaneously, the external intelligent controller 15 controls the one-way solenoid valve 9 to open. Guided by gravity and the conical bottom guide plate 10, the lubricating fluid 16 drips onto the surface of the rotating rigid rope 3 through the one-way solenoid valve 9 and the guide hose located between the one-way solenoid valve 9 and the rotating rigid rope 3. As the rotating rigid rope 3 continues to rotate, the lubricating fluid 16 is evenly carried to its outer side, providing lubrication. During this process, the elastic connector 11 adjusts its position according to the operating state of the rotating rigid rope 3. The contact pressure between the adjustable arc-shaped contact block 12 and the rotating rigid rope 3 is adjusted dynamically. The flexible protruding bristle inner layer 14 at the end of the adjustable arc-shaped contact block 12 contacts the rotating rigid rope 3, allowing the auxiliary lubricating liquid 16 to more evenly blend with the surface of the rotating rigid rope 3, improving the lubrication effect. When the ladder truck stops operating, the external intelligent controller 15 receives a stop signal and controls the electromagnetic matching block 13 to generate magnetic force, magnetically attracting the adjustable arc-shaped contact block 12 outward, so that the flexible protruding bristle inner layer 14 does not make close contact with the surface of the rotating rigid rope 3, avoiding the two from being in close contact due to prolonged static contact. To prevent wear caused by contact, the external intelligent controller 15 uses the level information of the lubricating liquid 16 in the inner oil storage hollow tank 8 monitored by the level sensor. If the liquid level is lower than the set value, it will remind the staff to add lubricating liquid 16 to the inner oil storage hollow tank 8 through the top replenishment hole 7 via indicator light or remote signal. Through the coordinated work of various components, effective anti-loosening and automatic lubrication of the steel wire rope of the ladder truck are achieved. The external intelligent controller 15, as the control core, accurately regulates the operating status of each component to ensure that the device can work stably and efficiently under different working conditions.
