Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile accessory processing, especially to a falling detection device and longitudinal beam transportation equipment. BACKGROUND

[0002] The frame is the most important load-bearing component in the automobile, and the longitudinal beam is one of the key parts. The longitudinal beam plays an important role in the automobile, and the side beam frame and the middle beam frame of the automobile all contain the longitudinal beam. The longitudinal beam is usually stamped from low alloy steel plate, and the cross section shape is generally a groove type, and some are made into Z type or box type cross section. The longitudinal beam is usually stored in an intelligent warehouse, and the longitudinal beam is magnetized by the magnetic attraction device on the conveying equipment and then transported to the designated position. Because the longitudinal beam has many types and different lengths, the conveying equipment has occurred many safety problems when the longitudinal beam is magnetized by the magnetic attraction device, such as the longitudinal beam falling from the magnetic attraction device and damaging the line of the turnover machine and the track of the RGV trolley. Even if the longitudinal beam does not fall, there may be a problem that the longitudinal beam is not firmly magnetized, that is, one end of the longitudinal beam is magnetized, and the other end is not magnetized, which causes serious safety hazards. These problems mainly occur because the longitudinal beam surface has too much oil and dust, the bending angle of the longitudinal beam is too large, or the position of the magnetic attraction device is located at the bolt position on the longitudinal beam, which causes insufficient magnetic attraction of the longitudinal beam by the magnetic attraction device. SUMMARY

[0003] The utility model discloses a falling detection device and longitudinal beam transportation equipment, which adds a detection device to the side of the conveying device. Whether the sensor at the bottom of the detection rod contacts the longitudinal beam determines the magnetic attraction state of the magnetic attraction device of the conveying device. This reduces the incidence of production safety hazards and has a simple structure and convenient use.

[0004] The utility model provides the following scheme:

[0005] In the first aspect, the utility model discloses a falling detection device, which comprises a mounting seat, the mounting seat is installed on the side of the conveying device, and the mounting seat is provided with a through channel;

[0006] A detection rod is arranged in the middle of the channel and slides up and down along the channel. The upper end and the lower end of the detection rod extend out of the channel. A limiting block is arranged at the top of the detection rod. A sensor is arranged at the bottom of the detection rod. The length of the detection rod is greater than the height of the conveying device.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The mounting seat of the utility model is installed on the side of the conveying device to move up and down with the conveying device, and when the detection rod in the mounting seat moves downward to touch the longitudinal beam, the longitudinal beam grabbing condition is obtained through the inductor. Because the shapes of the longitudinal beam parts are different, the height of the longitudinal beam middle part contacted by the conveying device and the longitudinal beam end part contacted by the detection rod relative to the ground may be different, therefore the length of the detection rod is set to be greater than the height of the conveying device, and the detection rod can slide in the channel, the detection rod first touches the longitudinal beam end part and slides upward in the channel for a distance, and then the conveying device contacts the longitudinal beam, so that the inductive precision is improved, the occurrence rate of production safety hazards is reduced, and the structure is simple and convenient to use.

[0016] 2. The inductor of the utility model is a photoelectric sensor or a contact inductor. When the photoelectric sensor is adopted, the photoelectric sensor also contacts the longitudinal beam when the bottom of the detection rod contacts the longitudinal beam, at this time, the photoelectric sensor cannot collect the light signal, so that it is determined that the longitudinal beam is grabbed by the conveying device; when the contact inductor is adopted, the contact inductor also contacts the longitudinal beam when the bottom of the detection rod contacts the longitudinal beam, at this time, the contact inductor senses the existence of the longitudinal beam, so that it is determined that the longitudinal beam is grabbed by the conveying device.

[0029] Embodiment 1

[0030] Referring to Figs. 1-2 As shown in the figure, the shedding detection device provided by the embodiment of the application comprises:

[0031] The mounting seat 2 is mounted on the side of the conveying device 1, and the mounting seat 2 is provided with a through channel 21.

[0032] The detection rod 3 is arranged in the middle part of the channel 21 and slides up and down along the channel 21, the upper end and the lower end of the detection rod 3 extend out of the channel 21, the top of the detection rod 3 is provided with a limiting block 31, the bottom of the detection rod 3 is provided with a sensor 32, and the length of the detection rod 3 is greater than the height of the conveying device 1.

[0033] The mounting seat 2 is mounted on the side of the conveying device 1 to follow the up and down movement of the conveying device 1, and when the detection rod 3 in the mounting seat 2 follows the downward movement of the conveying device 1 to touch the longitudinal beam, the sensor 32 obtains the information of the longitudinal beam. Since the shapes of the longitudinal beam are different, the heights of the middle part of the longitudinal beam contacted by the conveying device and the end part of the longitudinal beam contacted by the detection rod 3 relative to the ground can be different, therefore, the length of the detection rod 3 is set to be greater than the height of the conveying device 1, and the detection rod 3 can slide in the channel 21, the detection rod 3 first touches the end part of the longitudinal beam and slides upward in the channel 21 by a distance, and then the conveying device 1 contacts the longitudinal beam, so as to improve the sensing accuracy. When the conveying device 1 separates from the longitudinal beam and moves upward to grasp the next longitudinal beam, the detection rod 3 slides downward along the channel 21 under the action of its own gravity until the lower end of the limiting block 31 contacts the mounting seat 2.

[0034] Referring to Figs. 1-2 As shown in the figure, the sensor 32 is a photoelectric sensor or a contact sensor.

[0035] When the photoelectric sensor is used, the photoelectric sensor also contacts the longitudinal beam when the bottom of the detection rod 22 contacts the longitudinal beam, at this time the photoelectric sensor cannot collect the light signal, thereby determining that the longitudinal beam is gripped by the conveying device; when the contact sensor is used, the contact sensor also contacts the longitudinal beam when the bottom of the detection rod 22 contacts the longitudinal beam, at this time the contact sensor senses the existence of the longitudinal beam, thereby determining that the longitudinal beam is gripped by the conveying device.

[0036] Referring to Figs. 1-2 As shown in the figure, the diameter of the detection rod 3 is smaller than the diameter of the channel 21, and the diameter of the limiting block 31 is larger than the diameter of the channel 21, and the lower end of the limiting block 31 is provided with a buffer pad 311.

[0037] The diameter of the detection rod 3 is smaller than the diameter of the channel 21, which ensures that the detection rod 3 can slide along the channel 21, and the diameter of the limiting block 31 is larger than the diameter of the channel 21, which can avoid the detection rod 3 from falling out of the channel 21 during the sliding process, in the embodiment, the buffer pad is a damping pad, which avoids the mounting seat 2 driven by the conveying device 1 from moving upward too fast, and when the detection rod 3 falls under the action of its own gravity, the limiting block 31 collides with the mounting seat 2, damaging the limiting block 31.

[0038] Referring to Figs. 1-2 As shown in the figure, the limiting block 31 is detachably connected with the detection rod 3.

[0039] The limiting block 31 is detachably connected with the detection rod 3 through threads, when the detection rod 3 needs to be replaced due to problems, the detection rod can be removed by detaching the limiting block 31 from the detection rod 3, in addition, when the detection rod 3 needs to be placed in a channel 21 of different diameter for use, different diameters of the limiting block 31 can be replaced to achieve the purpose.

[0040] Referring to Figs. 1-2 As shown in the figure, the mounting seat 2 is provided with a fixed plate 22, and the mounting seat 2 is detachably connected with the conveying device 1 through the fixed plate 22.

[0041] The mounting seat 2 is detachably connected with the conveying device 1 through the fixed plate 22, which is more stable after installation, and ensures that the opening direction of the channel is parallel to the movement direction of the conveying device 1, avoiding the detection rod 3 from contacting the longitudinal beam in an inclined state, and reducing the working precision of the inductor.

[0042] Further, the mounting seat 2 is provided with a sound prompting device and a signal prompting lamp.

[0043] The sound prompting device and the signal prompting lamp remind the operating personnel to come over in time from the two directions of hearing and vision.

[0046] The falling detection device is arranged on both sides of the conveying device 1, so as to solve the problem that the longitudinal beam is not firmly gripped and one end of the longitudinal beam is magnetized while the other end is not magnetized.

[0047] The conveying device 1 comprises a plurality of mechanical hands, and the bottom of each mechanical hand is provided with a magnetic attraction device.

[0048] The mechanical hand moves downward, the magnetic attraction device contacts the longitudinal beam, the magnetic attraction device generates an attractive force after being electrified, the longitudinal beam is attracted, and subsequent transportation work is completed.

[0049] Further, the control device connected with the inductor 32 is additionally arranged on the mechanical hand, the magnetic attraction state of the magnetic attraction device on the longitudinal beam is acquired in real time, and the running state of the mechanical hand is controlled in real time. When the inductor does not contact the longitudinal beam within a specified time, the control device controls the mechanical hand to stop.

[0050] The working principle of the utility model is as follows:

[0051] The magnetic attraction device is controlled by the mechanical hand to touch the longitudinal beam, the magnetic attraction device generates a magnetic force after being electrified to attract the longitudinal beam after touching the longitudinal beam, the inductor 32 on the detection rod 3 also contacts the longitudinal beam, then the mechanical hand moves the longitudinal beam to a specified position, in the process, the inductor 32 determines whether the magnetic attraction device attracts the longitudinal beam according to whether the inductor 32 contacts the longitudinal beam, when the magnetic attraction device does not attract the longitudinal beam, the worker is reminded to check by the sound prompt device and the signal prompt lamp.
