While improving work efficiency, protecting the personal safety of workers has become an essential and important part.

[0003] Traditionally, due to the relatively high dust concentration and low visibility underground, and at the same time, due to the large size of the roadheader equipment, and the operation position is generally set on the left side of the roadheader, the operator has a certain visual blind area and cannot see all the perspectives of the front cutting area. If someone strays into the front cutting area and the operator cannot detect and stop the machine in time, it is easy to cause harm to the personal safety of the personnel. In this case, it is very important to detect the personnel who have strayed into the front in time and stop the equipment operation.

[0004] Therefore, it can be seen that providing a protection device capable of detecting personnel in the dangerous area of a roadheader is an urgent problem to be solved in this field. Summary of the Utility Model

Detailed Embodiments

[0033] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model is further described below in conjunction with specific illustrations.

[0034] See Figures 1 - 3 , which shows a schematic structural diagram of the personnel detection and protection device for the dangerous area of the roadheader provided by the present utility model.

[0035] It can be seen from the figure that the personnel detection and protection device for the dangerous area of the roadheader provided by the present utility model includes a human body detection device 100 as a component.

[0036] The personnel detection and protection device for the dangerous area of the roadheader provided by the present utility model is applied to a roadheader, and can perform human body detection on the working area of the roadheader to avoid the situation where there is a human body in the working area and the roadheader causes harm to the human body.

[0037] The human body detection device 100 is arranged on the roadheader 10 through an angle adjustment component 300 and is communicatively connected to the control center of the roadheader 10. The human body detection device 100 can adjust the angle according to actual use requirements through the angle adjustment component 300, so as to improve the applicability;

[0038] The above-mentioned human body detection device 100 can perform real-time human body detection on the working area in front of the roadheader 10 based on infrared detection, and can form a corresponding stop signal and send it to the control center when a human body is detected.

[0039] In this solution, the human body detection device 100 detects the dangerous area in front of the roadheader 10. When it detects that a person enters the dangerous area, the human body detection device 100 timely sends a stop signal to the control center of the roadheader 10 to stop the roadheader 10 in time and protect the safety of personnel, which well solves the problem that the roadheader 10 in the prior art has a visual blind area and is easy to cause harm to the personnel in the dangerous area.

[0040] Furthermore, in this solution, when the human body detection device 100 detects that there are personnel in the working area, when the roadheader 10 is in the starting state, the human body detection device 100 forms a stop operation signal to make the roadheader 10 stop moving;

[0041] and when the roadheader 10 is in the non-starting state, the human body detection device 100 forms a stop start signal to make the roadheader 10 unable to start.

[0042] That is to say, if there are personnel in front when the roadheader 10 is started, it cannot be started. If personnel are detected to enter during the operation of the roadheader 10, the equipment operation is stopped to prevent harm to the staff.

[0043] Specifically, the human body detection device 100 includes a first acquisition component 110 and a second acquisition component 120;

[0044] The first acquisition component 110 and the second acquisition component 120 are respectively arranged on both sides of the roadheader 10 through the angle adjustment component 300. The first acquisition component 110 and the second acquisition component 120 cooperate to form an induction area 200 in front of the roadheader 10, and this induction area 200 covers the working range of the roadheader 10.

[0045] Once a human body appears in the above-mentioned induction area, the first acquisition component 110 or the second acquisition component 120 can detect it and form a corresponding signal to send to the control center of the roadheader 10.

[0046] Furthermore, as Figure 2 , in this embodiment, the first acquisition component 110 and the second acquisition component 120 are preferably arranged on the covers 20 on both sides of the cutting arm of the roadheader 10.

[0047] Furthermore, the first acquisition component 110 and the second acquisition component 120 with such a structure cooperate with the angle adjustment component 300 to realize the adjustment of the angle.

[0048] As Figure 3 , the angle adjustment component 300 includes two angle adjustment parts 310. The two angle adjustment parts 310 are respectively connected to the roadheader 10 and are respectively connected to the first acquisition component 110 and the second acquisition component 120, and can adjust the detection angle between the first acquisition component 110 and the second acquisition component 120.

[0049] As Figure 3 , the two angle adjustment parts 310 have the same structure. The angle adjustment part 310 includes a mounting seat 311 and a connecting seat 312. One end of the mounting seat 311 is fixedly connected to the roadheader 10, and the other end is movably connected to one end of the connecting seat 312. The connecting seat 312 can rotate horizontally with respect to the mounting seat 311, and the other end of the connecting seat 312 is connected to the first acquisition component 110 or the second acquisition component 120;

[0050] One end of the above-mentioned connecting seat 312 can rotate horizontally with respect to the mounting seat 311, and the acquisition unit connected to the other end of the connecting seat 312 can thus realize horizontal rotation, so that the detection angle is changed through rotation. In this embodiment, the detection angle formed by the first acquisition component 110 and the second acquisition component 120 is preferably 120°.

[0051] Specifically, as Figure 3 , Figure 4 , an arc-shaped notch 311a is provided at the end of the top of the mounting seat 311 far from the roadheader 10, and a support seat 311b is provided at the bottom of the arc-shaped notch 311a. The support seat 311b is connected to the mounting seat 311a to block the bottom opening of the arc-shaped notch 311a for supporting the connecting seat 312;

[0052] One end of the connecting seat 312 is provided with a circular rotating shaft 312a. The circular rotating shaft 312 is embedded and installed along the top of the arc-shaped notch 311a and placed on the support seat 311b. The circular rotating shaft 312a can rotate in the arc-shaped notch 311a.

[0053] In order to further improve the reliability during the above rotation, a friction layer is provided on the surfaces of the circular rotating shaft 312a and the arc-shaped notch 311a. By setting the friction layer, the friction force between the two can be increased. In this way, after rotating to a certain angle, the circular rotating shaft 312a and the arc-shaped notch 311a can be relatively fixed.

[0054] It is also possible to set a connection hole on the circular rotating shaft 312. Correspondingly, a second connection hole communicating with the arc-shaped notch 311a is provided on the mounting seat 311. Fasteners are sequentially passed through the second connection hole and the connection hole on the circular rotating shaft 312 and connected to achieve the relative fixation of the two.

[0055] In order to further improve the reliability of the detection and protection device, the protection device further includes an acoustic and optical alarm component. The acoustic and optical alarm component includes a warning light and a buzzer. Both the warning light and the buzzer are connected to the control center of the roadheader 10.

[0056] During actual application, when the human body detection device 100 detects that there are people in the working area, the control center receives the signal and sends a start signal to the warning light and the buzzer. The warning light and the buzzer give continuous alarms of sound and light to remind the staff. When the detection signal of the human body detection device 100 disappears, the control center sends a stop signal to the warning light and the buzzer to turn off the warning light and the buzzer. In this way, it can timely remind the surrounding staff that someone has entered the dangerous area and speed up the reaction speed of the staff.

[0057] Furthermore, the above-mentioned first acquisition component 110 and the second acquisition component 120 have the same structure, and both include a protection housing 111 and an acquisition unit 112.

[0058] The protection housing 111 is detachably connected to the connecting seat 312 of the angle adjustment part 310. Through the detachable connection, when the protection housing 111 is damaged or needs to be replaced for other reasons, it can be quickly and conveniently disassembled and replaced.

[0059] The protection housing 111 is internally provided with a cavity. An installation bracket 111a is provided in the cavity. An opening 111b communicating with the cavity is provided on the side wall of the protection housing 111. The opening 111b allows infrared light to pass through and does not block the light emitted by the acquisition unit 112.

[0060] The acquisition unit 112 is installed on the installation bracket 111a, and the infrared light emitted by the acquisition unit 112 is emitted to the outside through the opening 111b.

[0061] Due to the harsh working environment of the roadheader, in this solution, a protective housing 111 is provided to protect the acquisition unit 112, avoiding damage to the acquisition unit 112 during operation.

[0062] In some embodiments of the present utility model, the acquisition unit 112 is a human body infrared detector, and the human body infrared detector is preferably connected to the control center of the roadheader 10 in a wired manner.

[0063] This solution does not limit the connection method between the above-mentioned protective housing 111 and the connection seat 312, which can be determined according to actual needs. As an example, in this embodiment, a snap connection or a threaded connection is preferably adopted.

[0064] And this solution does not limit the structure of the above-mentioned opening 111b, which can be determined according to actual needs, as long as it is ensured that the opening 111b does not block the infrared light emitted by the acquisition unit 112.

[0065] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
