Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those of ordinary skill in the art, other accompanying drawings and other implementation methods can be obtained based on these accompanying drawings without creative work.

[0034] Embodiment 1:

[0035] like Figures 1 to 9 As shown, the guide shoe integrated track clamp of this embodiment includes a base frame 1, a left roller 2, a right roller 3, a rear roller 4, a left wheel frame 5, a right wheel frame 6, a rear wheel frame 7, a connecting rod 8, a left pressure regulating member 9, a right pressure regulating member 10, a rear pressure regulating member 11, a left limit member 12, a right limit member 13, a rear limit member 14, a left roller braking mechanism and a right roller braking mechanism.

[0036] Specifically, Figure 3As shown, the base frame 1 includes a base 1-1 and a stand 1-2 installed on the base 1-1, and also includes a top plate 1-3 installed on the top of the stand 1-2. The base 1-1 and the top plate 1-3 are respectively provided with opposite guide rail through-holes T so that the elevator guide rails can pass through; the cross-section of the stand 1-2 is a U-shaped structure, and a left lug 12a and a right lug 12b are respectively extended on the left and right sides of the stand 1-2, and a rear lug 12c is extended on the rear side of the stand 1-2. The left lug 12a is used for rotatably mounting the left wheel frame 5, the right lug 12b is used for rotatably mounting the right wheel frame 6, and the rear lug 12c is used for rotatably mounting the rear wheel frame 7.

[0037] The left roller 2 and the right roller 3 of this embodiment are located at the front side of the frame 1-2 and are in the same plane; the rear roller 4 is located at the rear side of the frame 1-2 and penetrates the frame 1-2, the plane where the rear roller 4 is located is perpendicular to the plane where the left roller 2 is located, and is located between the left roller 2 and the right roller 3, and the left roller 2, the right roller 3, and the rear roller 4 constitute a guide rail clamping position to clamp the elevator guide rail. Specifically, each of the above rollers is fixedly mounted on its corresponding wheel frame through its wheel axle, and the roller and the wheel axle are matched through bearings. The matching structure between the wheel axle and the wheel frame and between the roller and the wheel axle belongs to the prior art and will not be repeated here.

[0038] The bottoms of the left wheel frame 5 and the right wheel frame 6 are connected by a connecting rod 8, which penetrates the vertical frame 1-2 to achieve synchronous linkage between the left wheel frame 5 and the right wheel frame 6, ensuring that the car moves with the car when it deviates without causing changes in friction resistance. Specifically, the two ends of the connecting rod 8 penetrate the left wheel frame 5 and the right wheel frame 6 respectively and are fixed by nuts.

[0039] The left pressure regulating member 9 of this embodiment is installed between the left wheel frame 5 and the stand 1-2, the right pressure regulating member 10 is installed between the right wheel frame 6 and the stand 1-2, and the rear pressure regulating member 11 is installed between the rear wheel frame 7 and the stand 1-2. The structures of the above pressure regulating members are the same. Here, only the structure of the left pressure regulating member 9 is taken as an example for detailed description. Figure 4 As shown, the left pressure regulating member 9 includes a screw rod 9-1, a spring 9-2, a spring seat 9-3 and a nut 9-4. The right end of the screw rod 9-1 is fixed to the upright frame 1-2 of the base frame, and the left end passes through the left wheel frame 5, the spring 9-2, the spring seat 9-3 in sequence and is fixed by the nut 9-4. The two ends of the spring 9-2 are respectively abutted against the left wheel frame 5 and the spring seat 9-3. By installing in this way, the compression amount of the spring 9-2 can be adjusted by the nut 9-4, thereby adjusting the preload force between the left roller 2 and the elevator guide rail.

[0040] The left stopper 12 of this embodiment is installed between the left wheel frame 5 and the stand 1-2, the right stopper 13 is installed between the right wheel frame 6 and the stand 1-2, and the rear stopper 14 is installed between the rear wheel frame 7 and the stand 1-2. The structures of the above-mentioned stoppers are the same. Here, only the structure of the right stopper 13 is taken as an example for detailed description. Figure 4 As shown, the right limit member 13 includes a screw rod 13-1, a limit block 13-2 and a nut 13-3. The left end of the screw rod 13-1 is fixed to the upright frame 1-2 of the base frame, and the right end passes through the right wheel frame 6 and the limit block 13-2 in sequence and is fixed by the nut 13-3. The distance between the limit block 13-2 and the right wheel frame 6 is adjusted by the nut 13-3 to realize the rotation stroke limit of the right wheel frame 6.

[0041] The left roller brake mechanism of this embodiment is used to brake the left roller in the target state, and the right roller brake mechanism is used to brake the right roller in the target state. Since the structure of the left roller brake mechanism is the same as that of the right roller brake mechanism, the specific structure and installation of the right roller brake mechanism are described in detail here, and the specific structure and installation of the right roller brake mechanism are not repeated here.

[0042] like Figure 5 and Figure 6 As shown, the right roller brake mechanism of this embodiment includes a brake disc 15, a friction plate 16 and a driving mechanism. The brake disc 15 is coaxially fixedly connected to the right roller 3. The brake disc 15 is located between the right roller 3 and its corresponding right wheel seat L. The right wheel seat L is embedded and fixed on the front side of the right wheel frame 6. The friction plate 16 is located in the brake disc 15. The driving mechanism is used to drive the friction plate 16 to move radially along the brake disc 15 so as to frictionally contact the brake disc 15.

[0043] Specifically, Figures 6 to 9 As shown, the driving mechanism includes an electromagnet 17, a pressure plate 18, two guide rods 19, two trigger members 20, two wedge blocks 21, and two return springs 22. The pressure plate 18 is connected to one end of the guide rod 19, and the guide rod 19 passes through the right wheel seat L along its axial direction for guiding cooperation. The other end of the guide rod 19 is connected to the trigger member 20. The trigger member 20 is used to trigger its corresponding wedge block 21 to move radially and outwardly along the brake disc 15. The friction plate 16 is fixed to the periphery of the wedge block 21. The structure of the friction plate 16 is adapted to the inner diameter structure of the brake disc, so that the friction plate and the brake disc can be in contact and friction. Among them, the wedge block 21 has a waist-shaped hole 210, which is fixed to the right wheel seat L by a stud K passing through the waist-shaped hole 210, which can not only realize the fixation of the wedge block 21, but also realize the radial movement of the wedge block 21 along the brake disc 15.

[0044] Among them, the two guide rods 19 are respectively located on the upper and lower sides of the wheel axle Q, and the two trigger members 20 are respectively located on the upper and lower sides of the wheel axle, and are drivingly connected to the two guide rods 19 in a one-to-one correspondence; the two wedge blocks 21 are respectively located on the left and right sides of the wheel axle; the two return springs 22 are respectively located on the upper and lower sides of the wheel axle, and the two ends of the return spring 22 are respectively connected to the two wedge blocks, which are used to reset the wedge blocks 21 along the radial outward movement of the brake disc.

[0045] The electromagnet 17 of this embodiment is installed on the rear side of the right wheel frame 6, and is used to attract the pressure plate 18 when powered.

[0046] The trigger member 20 of this embodiment includes a mounting frame 201 and rollers 202 mounted on the left and right sides of the mounting frame 201. The mounting frame 201 is fixedly connected to the guide rod 19, and the two rollers 202 are in contact with the inclined surfaces X of the two wedge blocks 21 respectively.

[0047] The guide shoe integrated rail clamp of this embodiment is installed in the car. When the car reaches the target floor, the electromagnet is energized to attract the pressure plate, and the roller of the triggering member is linked by the guide pull rod. The roller links the wedge block along the radial direction of the brake disc and moves outward, so that the friction plate contacts the brake disc for friction braking, thereby achieving left and right roller braking and preventing the elevator car from shaking. Among them, the inclined surface of the electromagnetic trigger wedge block is used to open the locking roller brake, which has wear compensation locking torque and improves reliability. As the friction parts wear, the gap between the pressure plate and the electromagnet becomes smaller and smaller, the magnetic attraction force becomes larger and larger, and the reliability of braking becomes higher and higher.

[0048] Embodiment 2:
