[0022] The present invention will be further clarified below with reference to the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, various equivalent forms of modification of the present invention fall within the scope defined by the appended claims of this application.

[0023] An assembly device for a monorail vehicle body, such as Figures 1-4 shown, comprising four brackets 1, a cross bar 2, and a cross member 3. The four brackets 1 are respectively a bracket one, a bracket two, a bracket three, and a bracket four. The bracket one and the bracket two are fixedly connected by the cross bar 2, and are bolted between the bracket one, the bracket two and the cross bar 2. The bracket three and the bracket four are fixedly connected by the cross bar 2, and are bolted between the bracket three, the bracket four and the cross bar 2. The bracket two and the bracket three are fixedly connected by the cross member 3, and are bolted between the bracket two, the bracket three and the cross member 3. The distance between the bracket two and the bracket three is greater than the distance between the bracket one and the bracket two. The distance between the bracket two and the bracket three is greater than the distance between the bracket three and the bracket four.

[0024] The bracket 1, such as Figure 3 shown, comprises a rectangular bracket, two left and right adjustment units 11, and four side wall fixing parts for fixing the side wall of the monorail vehicle body; the rectangular bracket comprises a left column 13, a right column, and two connecting rods 12. The two connecting rods 12 are divided into an upper connecting rod and a lower connecting rod. The left column 13, the upper connecting rod, the right column, and the lower connecting rod are sequentially connected to form a rectangular bracket (in the left column 13, the upper connecting rod, the right column, and the lower connecting rod, the words indicating directions left, right, up, and down are determined according to Figure 3 the direction shown). The two left and right adjustment units 11 are divided into a lower left and right adjustment unit and an upper left and right adjustment unit. The lower left and right adjustment unit is installed on the lower connecting rod, and the upper left and right adjustment unit is installed on the upper connecting rod; the left and right adjustment unit 11 comprises a fixing plate 111 and two adjustment mechanisms. The two adjustment mechanisms are divided into a left adjustment mechanism and a right adjustment mechanism. The fixing plate 111 is installed on the connecting rod 12, and the left adjustment mechanism and the right adjustment mechanism are respectively installed at the left and right ends of the fixing plate 111.

[0025] The adjusting mechanism includes a fixed seat 112, a first nut 113, a second nut 114, a first screw rod 115, a fixed sliding groove 116, and a sliding rod 117. The side wall fixing part includes a round tube 118 and a positioning pin 119. The fixed seat 112 and the fixed sliding groove 116 are installed on the fixing plate 111. A screw rod through hole is provided on the fixed seat 112. The first screw rod 115 passes through the screw rod through hole. The first nut 113 and the second nut 114 are installed on the first screw rod 115, and the first nut 113 and the second nut 114 are respectively located on both sides of the screw rod through hole. The sliding rod 117 is installed on the fixed sliding groove 116, and the sliding rod 117 is slidably connected to the fixed sliding groove 116. One end of the sliding rod 117 is fixedly connected to the round tube 118, and the other end is fixedly connected to the first screw rod 115. The positioning pin 119 is used to fixedly connect the process hole of the side wall of the monorail vehicle body to the round tube 118. During adjustment, loosen the first nut 113 and the second nut 114, push the round tube 118, and then push the sliding rod 117 to move in the fixed sliding groove 116, thereby moving the first screw rod 115. When the round tube 118 moves to the required position, stop moving. At this time, tighten the first nut 113 and the second nut 114 to fix the moving first screw rod 115 to the fixed seat 112. Therefore, if it is necessary to increase the distance between the side walls on both sides of the monorail vehicle body, only two corresponding round tubes 118 need to move outward and then be fixed; if it is necessary to decrease the distance between the side walls on both sides of the monorail vehicle body, only two corresponding round tubes 118 need to move inward and then be fixed. The present invention can adjust the distance between the two side walls through the adjusting unit, thereby realizing the positioning of the side walls. The main body of the present invention is designed to be detachable, which can position the side walls, and can realize the positioning of the side walls and the underframe in the height and vehicle length directions, the position of the door opening between the side walls, and the positioning relative to the opening between the upper parts of the side walls.

[0026] The present invention adopts a metal skeleton, which is composed of four brackets 1, several cross bars 2 and cross braces 3. The middle of the metal frame is a hollow structure, which greatly expands the working space. The main structure is detachable, which is convenient for the storage of the device. When in use, the device is fixed on the underframe, and the positioning pin 119 is inserted into the process hole of the side wall and the round tube 118, ensuring the accurate positioning of the side wall on the vehicle body. After the vehicle body is assembled, only the positioning pin 119 needs to be pulled out to disassemble the device. By adjusting the adjusting unit on the bracket, the positioning of the side wall and the underframe in the height and vehicle length directions, the position of the door opening between the side walls, and the positioning relative to the opening between the upper parts of the side walls can be realized. The cross bars and cross braces are detachable. The adjusting unit on the bracket is used to position the side wall and the door opening, and the side wall is fixed by the cooperation of the positioning pin on the bracket and the process hole on the side wall. A device with a mechanical structure is used to position and assemble the vehicle body. The device is light and practical, can adapt to the assembly of vehicle bodies of different models, and can well solve the problems such as inaccurate positioning in the assembly of vehicle bodies in the track vehicle production line. The structure is light and the strength is reliable, which is a practical device suitable for on-site production operations.

[0027] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
