[0031] In one embodiment, as shown in Figure 1 and Figure 2 The utility model provides a kind of comprehensive excavation working face lifting beam auxiliary device that can be used in cooperation with cantilever excavator, comprising:

[0032] The fixed plate 100 is fixedly assembled to the first flange plate 500, the first flange plate 500 is located between the cutting reducer 600 and the cutting motor box, and the plane where the fixed plate 100 is located is parallel to the plane where the first flange plate 500 is located. The support base 200 is rotationally connected with the fixed plate 100 through the rotating pin shaft 210.

[0033] The support beam 300 is arranged perpendicularly to the rotating pin shaft 210, and one end of the support beam 300 is fixedly connected with the support base 200. The bearing frame 400 for placing the top beam of the shed support is fixedly connected with the other end of the support beam 300.

[0034] In the embodiment, the length of the support beam 300 is greater than the axial length of the cutting reducer 600 and the cantilever 700.

[0035] Specifically, the support base 200 is rotationally connected with the fixed plate 100 through the rotating pin shaft 210, so that the support base 200 can rotate around the rotating pin shaft 210. When the lifting assistance is needed, the whole composed of the support base 200, the support beam 300 and the bearing frame 400 is rotated to the side of the first flange plate 500 facing the cutting head 800, so that the bearing frame 400 abuts against or extends out of the cutting head 800. Then the top beam to be lifted is placed on the bearing frame 400, the top beam is lifted by controlling the cantilever 700, then the shed leg is installed, and after the installation of the shed leg is completed, the cantilever 700 is lowered, the whole composed of the support base 200, the support beam 300 and the bearing frame 400 is rotated to the side of the first flange plate 500 facing the cutting motor box, so as to avoid the influence of the lifting assistance device on the working of the cutting head 800. The device of the embodiment can assist the workers in erecting the shed support and lifting the top beam, thereby reducing the labor intensity of the workers and improving the installation efficiency.

[0036] It should be noted that the plane where the fixed plate 100 is located is parallel to the plane where the first flange plate 500 is located, so that after the whole composed of the support base 200, the support beam 300 and the bearing frame 400 is rotated to the side of the first flange plate 500 facing the cutting head 800, the position of the whole assistance device is in a stable state.

[0037] In one embodiment, the end of the fixed plate 100 away from the rotating pin shaft 210 is in an arc shape, and the arc radius of the arc shape is greater than or equal to the axial radius of the cutting reducer 600; a plurality of connecting holes 110 are arranged on the fixed plate 100, the positional relationship of the plurality of connecting holes 110 is the same as the positional relationship of a plurality of assembly holes 120 distributed on the first flange plate 500 and connected with the connecting holes 110, and the plurality of connecting holes 110 and the plurality of assembly holes 120 are fixedly connected through bolts.

[0038] In the embodiment, the connecting holes 110 and the assembly holes 120 are equal in size, the arc-shaped structure can increase the contact area of the fixing plate 100 and the first flange plate 500, increase the matching number of the connecting holes 110 and the assembly holes 120, and improve the mounting and fastening of the fixing plate 100 and the first flange plate 500.

[0039] Since the plane where the fixing plate 100 is located is parallel to the plane where the first flange plate 500 is located, the same positional relationship means that the positional distribution of the plurality of connecting holes 110 and the plurality of assembly holes 120 on the two planes is the same, that is, the two planes coincide, and the positions of the plurality of connecting holes 110 and the plurality of assembly holes 120 also coincide.

[0040] In one of the embodiments, the support base 200 is provided with a bottom plate 220 and a first reinforcing plate 230, the first reinforcing plate 230 is fixedly connected to the top of the bottom plate 220, and one end of the support beam 300 is fixedly connected to the top of the first reinforcing plate 230.

[0041] The first reinforcing plate 230 serves to increase the connection strength of the base and the support beam 300, and in the extension direction of the support beam 300, the length of the first reinforcing plate 230 is greater than the length of the bottom plate 220, which can increase the supporting effect of the bottom plate 220 on the support beam 300 when the beam is raised.

[0042] In the embodiment, the rotating pin shaft 210 includes a first segment, a second segment, a third segment, a fourth segment, and a fifth segment, the first segment, the third segment, and the fifth segment are associated with rotation, and the second segment and the fourth segment are associated with rotation; the side wall of the bottom plate 220 close to the fixing plate 100 is fixedly connected with the first segment, the third segment, and the fifth segment, and the side wall of the fixing plate 100 close to the bottom plate 220 is fixedly connected with the second segment and the fourth segment.

[0043] The rotating pin shaft 210 divides the fixing plate 100 and the bottom plate 220 into segments to be connected in rotation, which can prevent the fixing plate 100 and the bottom plate 220 from being dislocated in the axial direction of the rotating pin shaft 210. In addition, the first segment, the third segment, and the fifth segment can also be driven to rotate by installing a motor and a gear, so as to realize the rotation of the support base 200 and the support beam 300 and the carrier frame 400 as a whole, and more manpower is saved.

[0044] In one embodiment, the support beam 300 and the carrier frame 400 are both in the structure of a channel steel, and the end of the support beam 300 fixedly connected with the carrier frame 400 is provided with a second reinforcing plate 310, and the second reinforcing plate 310 is arranged inside the channel steel structure; the second reinforcing plate 310 is in the shape of a right triangle, and the two right-angle side walls of the second reinforcing plate 310 are respectively fixedly connected with a side wall of the carrier frame 400 and the bottom of the channel steel structure.

[0045] The second reinforcing plate 310 serves to increase the connecting area of the bearing frame 400 and the support beam 300, improve the connecting fastening, and increase the bearing weight of the bearing frame 400.

[0046] In one of the embodiments, the top and bottom of the bearing frame 400 are covered with rubber layers which are fixedly connected with the bearing frame 400. The rubber layers serve to prevent the bearing frame 400 from being damaged by collision with the boom header.

[0047] In one of the embodiments, the boom header auxiliary device for the combined boom header working face further comprises a safety module for controlling the rotation function locking of the cutting head 800 and a position sensor for detecting the position of the support beam 300, the position sensor being electrically connected with the safety module, and the safety module being electrically connected with the rotation controller of the cutting head 800.

[0048] In the embodiment, the safety module can be an electric control button which is electrically connected with the rotation controller of the cutting head 800, and is internally provided with a PLC controller for receiving the signal of the position sensor, and can artificially control the emergency stop of the cutting head 800, or can control the emergency stop of the cutting head 800 according to the signal of the position sensor. When the signal fed back by the position sensor is that the position of the support beam 300 is on the side of the first flange plate 500 facing the cutting head 800, the PLC controller controls the emergency stop of the cutting head 800. The setting of the safety module can prevent the boom header auxiliary device in the embodiment from being damaged by the rotation of the cutting head 800 during the boom lifting and causing accidents.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
