[0041] The angle adjustment screw 106 is threadedly connected to the left end fixing block 107 to form a self-locking structure of the escalator angle adjustment mechanism. The front end of the angle adjustment screw 106 is against the round sleeve 108 connected to the thrust plate 109. Two square connectors 104 are fixed on the thrust plate 109. The two square connectors 104 are each rotatably connected to the lower end of a No. 1 connecting rod 103 through a No. 1 rotating shaft 112. The upper end of the No. 1 connecting rod 103 and the upper end of the No. 2 connecting rod 111 are rotatably connected through a No. 2 rotating shaft 116. The upper end of the No. 2 connecting rod 111 is also provided with a protruding portion that cooperates with the connecting plate 101. The lower end of the No. 2 connecting rod 111 is rotatably connected to the support 113 through a No. 3 rotating shaft 117. Limit nuts 102 are provided at both ends of the No. 1 rotating shaft 112, the No. 2 rotating shaft 116 and the No. 3 rotating shaft 117 to prevent axial sliding. A No. 1 threaded hole is formed on the upper protruding portion of the No. 2 connecting rod 111 , and the No. 1 threaded hole and the upper connecting bolt 110 are used to fix the No. 2 connecting rod 111 to the connecting plate 101 .

[0042] When the angle needs to be adjusted, the angle adjustment handle 105 is turned to drive the angle adjustment screw 106 to rotate forward. The angle adjustment screw 106 pushes the circular sleeve 108 connected to the propulsion plate 109. The circular sleeve 108 transmits the movement through the square connecting head 104 to the No. 1 connecting rod 103 and the No. 2 connecting rod 111. The connecting plate 101 is lifted by the raised part on the No. 2 connecting rod 111, so that the connecting plate rotates to a certain angle. After the adjustment is completed, since the left end fixing block 107 is threadedly connected to the angle adjustment screw 106, the mechanism has self-locking properties to prevent the angle from swinging.

[0043] like Figure 4-6As shown, the escalator height adjustment mechanism 2 includes a frame 201, a first wedge 202, a second wedge 203, a support column 204, a sliding block 205, a height adjustment screw 206 and a height adjustment handle 207. The frame 201 is L-shaped, and track grooves are provided in the upper and lower parts thereof, for the first wedge 202 and the second wedge 203 to slide in.

A shoulder 209 is provided at the end of the height adjustment screw 206, a slot 210 matching the shoulder 209 is provided at one end of the sliding block 205, a support block 208 is provided on the right side of the frame 201, the support block 208 is integrally formed with the frame 201, and the second threaded hole is located on the support block 208. The frame 201 is fixed on the escalator width adjustment mechanism, the height adjustment screw 206 drives the second angled wedge 203 to move horizontally through the sliding block 205, the second angled wedge 203 drives the first angled wedge 202 to move vertically, and the first angled wedge 202 drives the support column 204 to move up and down.

[0044] When adjusting the height, the height adjustment handle 207 is rotated to drive the height adjustment screw 206, the height adjustment screw 206 drives the sliding block 205, the sliding block 208 pushes the No. 2 bevel 203, the No. 2 bevel 203 drives the No. 1 bevel 202, the No. 1 bevel 202 pushes the support column 204, the support column 204 lifts the support plate 115 in the angle adjustment mechanism connected to it, thereby raising the height of the entire height adjustment mechanism.

[0045] The first wedge 202 of the escalator height adjustment mechanism 2 pushes the support column 204 to raise the height of the entire device. At the same time, due to the self-locking property of the threaded connection between the frame 201 and the height adjustment screw 206, the sliding block firmly presses against the second wedge 203, and the second wedge 203 firmly presses against the first wedge 202 to prevent sinking, making the structure more solid and reliable.

[0046] like Figure 7-9 As shown, the escalator width adjustment mechanism 3 includes a fixing screw 301 , a locking bolt 302 , a telescopic connector 303 and two cross beams 304 .

[0047] One end of the crossbeam 304 is connected to the frame 201 by a fixing screw 301, and the two crossbeams 304 are inserted through the openings in front and behind the telescopic connector 303, and the crossbeam 304 is provided with spaced limiting circular holes. The spacing of the limiting circular holes varies according to the existing escalator standard rules, and the upper end of the telescopic connector is provided with two threaded holes, which are connected with locking bolts 302, and one end of the crossbeam 304 is provided with a connector 305, which is fixed to the frame 201 by a fixing screw 301.

[0048] When adjusting the width that the crossbeam 304 needs to support, the crossbeam 304 is moved inward or outward to the width distance that needs to be adjusted. At this time, the limiting circular holes on the crossbeam arranged at regular intervals are aligned with the threaded adjustment holes on the telescopic connecting head, and the locking bolts 302 pass through the threaded adjustment holes and the limiting circular holes in turn, thereby playing a fixing role.

[0049] Since the openings on the middle crossbeam are arranged at standard intervals according to the escalator width, the width adjustment mechanism can adjust the width according to the escalator standard, making it easy to adjust and eliminating the tedious steps of measurement during adjustment. At the same time, it can effectively prevent the crossbeam from moving in the axial direction after adjustment, making it firm and reliable.

[0050] A method for adjusting a middle support device of an adjustable escalator,

[0053] When the escalator width needs to be adjusted, loosen the locking bolt to allow one end of the beam to move inward or outward in the telescopic connector to the width distance that needs to be adjusted. At this time, the limiting circular holes on the beam arranged at regular intervals are aligned with the threaded adjustment holes on the telescopic connector, and the locking bolt passes through the threaded adjustment holes and the limiting circular holes in turn, thereby playing a fixing role.

[0054] The present invention combines the escalator height adjustment mechanism, the escalator angle adjustment mechanism and the escalator width adjustment mechanism together, wherein in the escalator height adjustment mechanism, a pair of inclined wedges are designed to have self-locking properties, and at the same time, the threaded hole on the right side of the frame and the height adjustment screw have self-locking properties, which can achieve double self-locking after the height adjustment is completed. In the escalator angle adjustment mechanism, the left end fixed block has a threaded hole, which forms a self-locking with the angle adjustment screw, and can be locked after the angle adjustment is completed. In the escalator width adjustment mechanism, the locking nut is used to cooperate with a plurality of limiting circular holes on the beam, so that the width can be adjusted according to the standard law of the escalator width, and the axial movement of the beam can be effectively prevented.

[0055] The invention can meet the support requirements of escalators of different heights, different angles and different widths.
