Abstract

This utility model discloses a crane length measuring sensor device and a crane outrigger, including a length measuring sensor pull rope end, a length measuring sensor pull rope drum, a length measuring sensor encoder and control unit, and a steel wire pull rope. The length measuring sensor encoder and control unit are arranged vertically above and below the length measuring sensor pull rope drum. The steel wire pull rope passes through the length measuring sensor pull rope drum, separating the steel wire pull rope from the electronic components. The wire outlets on both sides of the length measuring sensor pull rope drum are arc-shaped and symmetrically arranged, allowing the steel wire pull rope to extend and retract simultaneously from both sides.

Separating the electronic components from the pull rope drum prevents impurities from entering the sensor and causing damage.

Description

Technical Field

[0001] This utility model relates to the field of cranes, and in particular to a crane length measuring sensor device and a crane outrigger. Background Technology

[0002] A truck crane is a heavy-duty piece of equipment used for lifting heavy objects, and outriggers are an important component. Depending on the operating conditions, outriggers have different operating states, such as fully extended, partially extended, and fully retracted. A length measuring sensor is used to measure the extended length of the outriggers. One end of the outrigger measuring sensor is fixed to the fixed outrigger, and the other end is fixed to the movable outrigger. When the movable outrigger extends outward, it pulls out the steel cable of the length measuring sensor, thus measuring the extended length of the outrigger.

[0003] Existing length measuring sensors, such as the length measuring sensor device in patent CN205619911U, place the steel wire rope inside the sensor body, and the outlet hole is relatively small. During the actual assembly of crane outriggers, due to assembly errors, it is difficult to ensure that the steel wire rope of the length measuring sensor remains parallel to the outlet hole when extended. Furthermore, as the movable outrigger extends, the vertical distance between the two ends of the length measuring sensor gradually increases, causing the steel wire rope to deviate from its parallel position after extension, thus accelerating the damage to the length measuring sensor.

[0004] Therefore, it is necessary to develop new crane length measuring sensor devices to overcome the problems of existing technologies and extend the service life of the sensors. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a crane length measuring sensor device and crane outrigger, which avoids the wear of the cable of the length measuring sensor during the extension and retraction process due to stretching and the cable outlet hole, thereby improving the service life of the cable; and separates the electronic components from the cable reel, thereby preventing impurities from entering the sensor and causing damage.

[0007] The steel wire rope is parallel to the outlet of the length measuring sensor rope reel.

[0008] The upper and lower parts of the length measuring sensor pull rope drum are not enclosed.

[0009] The encoder and control unit of the length measuring sensor are placed outside the length measuring sensor pull rope drum.

[0010] The four rounded corners at the outlet of the length measuring sensor pull rope drum are all arc-shaped baffles.

[0011] The present invention relates to a crane outrigger, characterized in that: the crane length measuring sensor device of the present invention is used, wherein the pull rope ends of the two length measuring sensors are respectively fixed to the fixed outrigger and the movable outrigger.

[0015] Figure 2 This is a schematic diagram of the structure of the crane outrigger of this utility model;

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] The fixed outrigger of this invention is a square box for the crane's outriggers, rigidly connected to the crane's frame structure and therefore immobile. The movable outrigger is a telescopic outrigger housed inside the fixed outrigger and capable of telescopic movement.

[0019] like Figure 1This utility model discloses a crane length measuring sensor device, comprising a length measuring sensor pull rope end 1, a length measuring sensor pull rope drum 2, a length measuring sensor encoder and control unit 3, and a steel wire pull rope 4. The length measuring sensor encoder and control unit 3 is arranged vertically above the length measuring sensor pull rope drum 2. The steel wire pull rope 4 passes through the length measuring sensor pull rope drum 2, separating the steel wire pull rope 4 from the electronic components. The wire outlets on both sides of the length measuring sensor pull rope drum 2 are arc-shaped and symmetrically arranged, allowing the steel wire pull rope 4 to extend and retract simultaneously from both sides. The steel wire pull rope 4 is parallel to the wire outlet of the length measuring sensor pull rope drum 2. The upper and lower parts of the length measuring sensor pull rope drum 2 are not enclosed. The length measuring sensor encoder and control unit 3 is placed outside the length measuring sensor pull rope drum 2. The four rounded corners at the wire outlet of the length measuring sensor pull rope drum 2 are all arc-shaped baffles.

[0020] The upper and lower parts of the length measuring sensor pull rope drum 2 of this invention are not enclosed. The length measuring sensor encoder and control unit 3 are placed outside the length measuring sensor pull rope drum 2. This design effectively prevents dust and other impurities adhering to the pull rope from entering the encoder. The winding drum inside the length measuring sensor pull rope drum 2 has a large tensile force, which keeps the pull ropes at both ends taut when pulled out. The four rounded corners at the wire outlet of the length measuring sensor pull rope drum 2 are all arc-shaped baffles, which ensure that the pull rope will not wear against the wire outlet within a certain angle range after being pulled out. The length measuring sensor encoder and control unit 3 has a built-in wireless gateway, which can wirelessly transmit measurement data to the receiving terminal. When the steel wire pull rope 4 extends, it extends to both sides simultaneously, thus ensuring that the steel wire pull ropes on both sides are parallel. Even if the pull rope ends of the length measuring sensors on both sides are not on the same horizontal line, the steel wire pull rope can still remain parallel to the wire outlet, avoiding friction with the edge of the wire outlet.

[0021] like Figure 2 The crane outriggers of this invention utilize the aforementioned crane length measuring sensor device. The rope ends 1 of the two length measuring sensors are respectively fixed to the fixed outrigger and the movable outrigger. The length measuring sensor encoder and control unit 3 are connected to the signal receiving end.

[0022] The two length measuring sensors of the above-mentioned new crane length measuring sensor have their rope ends 1 fixed to the movable outrigger and the fixed outrigger, respectively. When the outrigger moves to extend or retract, it will drive the steel wire rope 4 of the length measuring sensor to extend and retract simultaneously from both sides of the length measuring sensor rope drum 2. The length measuring sensor encoder and control part 3 will collect the displacement change of the steel wire rope 4 and wirelessly transmit the measurement data to the signal receiving end.

[0023] This invention makes the outlet of the length measuring sensor into an arc shape, ensuring that when the wire rope is pulled out, it can be pulled out tangentially within a certain angle to the outlet hole. At the same time, by changing the wire rope from extending from one side to extending from both sides, it can ensure that even if there is a vertical distance between the fixed points at both ends of the wire rope, the wire rope and the outlet remain parallel. This solves the problem of the wire rope breaking due to long-term friction between the right-angle edge of the outlet.

[0024] This invention solves the problem of impurities damaging the measuring device by placing the steel wire rope outside the sensor and separating it from the sensor's measuring part.

[0025] This invention employs a novel length measuring sensor structure, preventing wear between the pull rope and the outlet hole within a certain angle range after the rope is extended. The encoder and control components of the length measuring sensor are separated from the pull rope drum. Wireless data transmission effectively reduces the weight and size of the pull rope sensor body. This length measuring sensor is applicable to heavy-duty engineering machinery vehicles with outriggers, specifically cranes. This invention avoids wear between the pull rope and the outlet hole during extension and retraction, thus improving the rope's lifespan. Separating the electronic components from the pull rope drum prevents damage caused by impurities entering the sensor.
