DETAILED DESCRIPTION

[0023] like Figure 1-2 As shown, a recyclable prefabricated basement support plate belt support structure includes an outer support sleeve 1, which is made of square steel. An insertion position is provided at one end of the outer support sleeve 1, and an inner support sleeve 2 is inserted into the insertion position of the outer support sleeve 1. Both the outer support sleeve 1 and the inner support sleeve 2 are made of square steel, and the outer diameter of the inner support sleeve 2 is smaller than that of the outer support sleeve 1. The outer end of the inner support sleeve 2 is fixed on the support pile 3.

[0024] like Figure 2 As shown, a locking assembly 5 is provided inside the outer support sleeve 1. The locking assembly 5 enables the inner support sleeve 2 to slide relative to the outer support sleeve 1 and lock.

[0025] like Figure 3-4 As shown, the locking assembly 5 includes a connecting frame 51, the tail of which is fixed in the outer support sleeve 1, and the connecting frame 51 is arranged along the length direction of the axis of the center of the outer support sleeve 1. A socket is provided in the mounting seat at the head of the connecting frame 51 in both the horizontal and vertical directions, and the socket is used to insert the shaft pin 11.

[0026] The inner support sleeve 2 is provided with a slot 21 at a position corresponding to the shaft pin 11, and the slot 21 is arranged along the length direction, including a transverse slot 21 and a vertical slot 21. The width of the slot 21 is slightly larger than the outer diameter of the shaft pin 11, so that the shaft pin 11 can pass through the slot 21.

[0027] When the outer support sleeve 1 is sleeved on the inner support sleeve 2, the horizontal pin 11 passes through the through hole of the outer support sleeve 1, the horizontal slot 21 of the inner support sleeve 2 and the horizontal insertion hole of the connecting frame 51, and then the two ends are limited by the locking nuts 12; similarly, the vertical pin 11 passes through the through hole of the outer support sleeve 1, the vertical slot 21 of the inner support sleeve 2 and the vertical insertion hole of the connecting frame 51, and then the two ends are limited by the locking nuts 12. In this way, the inner support sleeve 2 and the outer support sleeve 1 can slide relative to each other and cannot be separated, forming a retractable whole.

[0028] At the same time, in order to realize the locking function, a vertical rod 52 is rotatably installed at the tail of the outer support sleeve 1, a knob 13 is fixed at the upper end of the vertical rod 52, and a driving bevel gear 53 is fixed at the lower end of the vertical rod 52 inside the outer support sleeve 1, and the driving bevel gear 53 is meshed with the driven bevel gear 54. The driven bevel gear 54 is fixed on a screw rod 58, and the screw rod 58 is located in the connecting frame 51 and arranged along the length direction. The screw rod 58 is rotatably installed on the connecting frame 51. A slide groove 56 is provided along the length direction on the side of the connecting frame 51 away from the driving bevel gear 53, and a slider 57 that slides along the slide groove 56 is threadedly connected on the surface of the screw rod 58. A connecting seat 59 is installed on both sides of the slider 57. The connecting seat 59 includes two sets of rotating shaft seats in a vertical direction and a horizontal direction. A first connecting rod 510 is rotatably installed on the surface of the vertical rotating shaft seat on the connecting seat 59, and the other end of the first connecting rod 510 is rotatably connected to the extrusion ring 55 at both ends of the vertical shaft pin 11 through a rotating shaft. The second connecting rod 511 is rotatably mounted on the horizontal rotating shaft seat surface of the connecting seat 59, and the other end of the second connecting rod 511 is rotatably connected to the side of the extrusion ring 55 at both ends of the horizontal shaft pin 11 through the rotating shaft. The extrusion ring 55 at both ends of each shaft pin 11 is slidably sleeved on the surface of the shaft pin 11.

[0029] During operation, after the two shaft pins 11 pass through the connecting frame 51, the knob 13 is turned, and the knob 13 drives the vertical rod 52 and the active bevel gear 53 to rotate, and the active bevel gear 53 meshes with the driven bevel gear 54, thereby driving the screw 58 to rotate, and the slider 57 moves along the slide groove 56, and through the hinged first connecting rod 510 and the second connecting rod 511, the extrusion ring 55 in four directions is pushed outward along the horizontal and vertical shaft pins 11 until it is squeezed with the inner wall of the inner support sleeve 2, thereby achieving locking. The vertical rod 52 at the rear end of the outer support sleeve 1 drives the screw 58 to rotate, which can avoid interference with the insertion position of the inner support sleeve 2.

[0030] Preferably, locking nuts 12 are threadedly connected on the surfaces of both ends of the shaft pin 11, and the locking nuts 12 are in compression contact with the outer wall of the outer support sleeve 1. The shaft pin 11 crosses through the outer support sleeve 1 and the inner support sleeve 2, and then cooperates with the locking nuts 12 to be in compression contact with the outer surface of the outer support sleeve 1, and the extrusion ring 55 to be in compression contact with the inner wall of the inner support sleeve 2, thereby improving the stability of the outer support sleeve 1 and the inner support sleeve 2 after plug-in installation.

[0031] Preferably, a U-shaped slot 14 is provided on the side of the outer support sleeve 1 away from the inner support sleeve 2, and the U-shaped slot 14 is clamped on the concrete floor 4 of the basement. The outer support sleeve 1 is clamped on the concrete floor 4 of the basement through the U-shaped slot 14, thereby completing the installation of the plate belt.

[0032] Preferably, the extrusion ring 55 can use a linear bearing to ensure smooth sliding along the axis direction of the shaft pin 11 to avoid jamming.

[0033] Working principle and process: When using this device, the inner support sleeve 2 is first fixed on the support pile 3, and then the outer support sleeve 1 is sleeved on the inner support sleeve 2. When the shaft pin 11 passes through the outer support sleeve 1 and the inner support sleeve 2, the outer support sleeve 1 can slide relative to the inner support sleeve 2, and then the length of the device after installation can be changed. After the two shaft pins 11 pass through the connecting frame 51, turn the knob 13, and the slider 57 can be driven to move along the slide groove 56 through the bevel gear transmission mechanism and the screw slider mechanism, and then the extrusion ring 55 in four directions is driven to push outward along the horizontal and vertical shaft pins 11 through the first connecting rod 510 and the second connecting rod 511, until it is squeezed and locked with the inner wall of the inner support sleeve 2, and then the locking nut 12 is screwed in and tightened.
