The present invention utilizes the horizontal accuracy of the car guide rail to cooperate with the fixed module to quickly connect with it, and can quickly build the platform module to assemble the car frame through the platform module, thereby improving the accuracy of the car frame assembly, thereby avoiding the problem that the car frame is not horizontal and needs to be constantly adjusted.

[0041] See also Figure 3 The fixed module 10 includes a fixed seat 110, and a guide plug-in portion 100 is arranged on the wall surface of the fixed seat 110 facing the car guide rail 30, and the car guide rail 30 is longitudinally inserted in the guide plug-in portion 100; the guide plug-in portion 100 cooperates with the car guide rail 30 to constrain the forward and backward movement of the fixed seat 110 relative to the car guide rail 30; the front and rear of the fixed seat 110 are respectively provided with clamping components 40, and the clamping components 40 are in contact with the wall surface of the car guide rail 30 facing away from the fixed seat 110; the fixed seat 110 is provided with a clamping component 50 for clamping the car guide rail 30 so that the fixed seat 110 cannot move downward relative to the car guide rail 30.

[0042] Furthermore, the guide plug-in part 100 is a cavity with upper and lower openings, and the cavity is opened toward one side of the car guide rail 30. During assembly, the car guide rail 30 can be inserted into the cavity. The guide plug-in part 100 is plugged into the car guide rail 30 to restrict the forward and backward movement of the fixed module 10 relative to the car guide rail 30.

[0043] The fixing module 10 can be clamped and fixed with the car guide rail 30 under the action of the clamping assembly 50, so as to be fixed in the hoistways at different heights, which is convenient for assembling the car frame.

[0044] The fixing seat 110 cooperates with the clamping assembly 40 to clamp the car guide rail 30 to restrict the left and right movement of the fixing module 10 relative to the car guide rail 30 .

[0045] See also Figures 3 to 5The clamping assembly 50 includes a mounting plate 510, which is movable up and down relative to the fixed seat 110, and a movable pin 520 is arranged at intervals on the mounting plate 510, and the movable pin 520 is arranged to move forward and backward relative to the mounting plate 510; a wedge 530 is rotatably arranged on the movable pin 520, and a locking space 500 is formed between the front and rear wedges 530, and the car guide rail 30 is at least partially inserted in the locking space 500; a driving pin 520 is arranged at intervals on the front and rear of the fixed seat 110. The driving element 120 has an end surface facing the wedge block 530 which is a first inclined surface; the end surface of the wedge block 530 which is facing the driving element 120 is a second inclined surface; the first inclined surface and the second inclined surface fit each other, and the left and right sides of the driving element 120 are fixedly connected with a guide plug-in 130, and the left and right walls of the wedge block 530 are respectively provided with guide inclined grooves 531, and the guide plug-in 130 is movably inserted in the guide inclined grooves 531, and the guide plug-in 130 can move forward and backward relative to the guide inclined grooves 531.

[0046] When in use, the car guide rail 30 is inserted into the locking space 500. As gravity moves downward, the mounting plate 510 drives the driving element 120 to press the wedge block 530 downward, so that under the action of the first inclined surface and the second inclined surface, it pushes the wedge block 530 to clamp the car guide rail 30, and at the same time, under the action of the first inclined surface and the second inclined surface, the wedge block 530 restricts the driving element 120 from moving downward.

[0047] In the present invention, the two left and right first inclined surfaces are arranged in an eight-shaped shape, and the two left and right second inclined surfaces are arranged in an eight-shaped shape.

[0048] In the present invention, the guide plug-in 130 is movably inserted into the guide inclined slot 531, which can constrain the left and right positions of the wedge block 530 and the driving element 120 to prevent the misalignment of the two and cause unlocking problems.

The rotating shafts 122 are arranged to maintain the smoothness of movement, to avoid interference between the first inclined surface and the second inclined surface and the inability to perform transmission cooperation, which results in the wedge block 530 not being clamped and unable to be locked.

[0050] The rotation setting of the rotating shaft 122 can ensure that under the action of gravity, the fixing seat 110 moves downward relative to the wedge block 530, and the driving block 121 squeezes the wedge block 530 to clamp the elevator guide rail 30.

[0053] Under the action of the elastic element 420, it drives the L-shaped clamping member 410 to move toward one side of the fixed seat 110, so as to clamp the car guide rail 30 to the left and right through the clamping section 412 of the fixed seat 110 and the L-shaped clamping member 410, effectively ensuring the left and right stability of the fixed module 10.

[0054] In the present invention, a guide shoe liner 101 which fits the car guide rail 30 is arranged in the guide plug-in portion 100 .

[0055] In the present invention, a concave-convex anti-skid texture is provided on the wall surface of the wedge block 530 facing the other wedge block 530, thereby increasing the friction coefficient between the wedge block 530 and the car guide rail 30 and improving the clamping stability.
