Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories, in particular to a roller guide shoe of a box-type elevator with stable operation. Background Art

[0002] The guide shoe is a sliding nylon block between the elevator guide rail and the car. It can fix the car on the guide rail so that the car can only move up and down. There is also an oil cup on the top of the guide shoe to reduce the friction between the shoe lining and the guide rail.

[0003] At present, traditional guide shoe technology mainly applies elastic pressure to the guide wheel through a transversely arranged spring, driving the guide wheel to be tightly attached to the guide rail. However, the deformation path of the guide wheel is nearly parallel to the deformation path of the spring, so the spring is more likely to deform, resulting in instability during the operation of the car. The patent document with the prior art publication number CN211594684U provides a box-type elevator roller guide shoe mechanism with smooth operation. The device is provided with a guide mechanism, so that the guide mechanism plays an adaptive function. During the operation of the elevator, it can be pressed against the elevator guide rail to prevent the elevator from shaking during movement, ensure the smoothness of movement during the movement of the elevator, ensure the smooth operation of the elevator, and improve the comfort of users.

[0004] Although the guide mechanism in the device can further improve the adaptability, the deformation direction of the spring is still in the same direction, which makes the stabilization effect on the car not obvious enough. Therefore, a box-type elevator roller guide shoe with smooth operation is urgently needed to solve the above problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0006] Specifically, the technical problem to be solved by the present invention is to provide a box-type elevator roller guide shoe with smooth operation, so as to solve the technical problem that although the current guide mechanism can further improve the adaptability, the deformation direction of the spring is still in the same direction as that of the spring, so that the stabilizing effect on the car is not obvious enough.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A box-type elevator roller guide shoe with smooth operation includes a mounting plate and three guide wheels, characterized in that: a connecting rod is rotatably connected to the guide wheel, a connecting plate is rotatably connected to one side of the connecting rod, the connecting plate is mounted on the mounting plate, a pulling spring is connected to the connecting plate and the end of the connecting rod close to the guide wheel, and a pushing assembly is connected to the connecting plate and the end of the connecting rod away from the guide wheel;

[0009] The pushing assembly includes a pushing spring, and both ends of the pushing spring are fixedly connected with a rotating seat, one of the rotating seats is rotatably connected to the connecting rod, and the other rotating seat is horizontally slidably arranged on the connecting plate.

[0010] As an improved technical solution, both ends of the pulling spring are fixedly connected with rotating blocks, and the two rotating blocks are respectively rotatably connected to the connecting rod and the connecting plate.

[0011] As an improved technical solution, a sliding rod is provided in the push spring, one end of the sliding rod is fixedly connected to a rotating seat, and the other end is slidably connected to another rotating seat.

[0012] As an improved technical solution, a slider is rotatably connected to the rotating seat, a screw is threadedly connected to the slider, and the screw is rotatably connected to the connecting plate.

[0013] As an improved technical solution, a slide is fixedly connected to the bottom of the connecting plate, the slide is slidably matched with the mounting plate, and a stud is threadedly connected to the slide, and the stud is rotatably connected to the mounting plate.

[0014] As an improved technical solution, one end of the stud is fixedly connected to a gear, one side of the gear is snap-fitted with a brake plate, and the end of the brake plate is elastically connected to the mounting plate via a brake spring.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] 1. The utility model pulls the spring and pushes the deformation direction of the spring to be non-perpendicular to the moving direction of the guide wheel, thereby increasing the difficulty of the guide wheel displacement, and the push spring cooperates with the connecting rod to form a labor-saving lever, so the guide wheel drives the connecting rod to rotate as a laborious movement, so that the guide wheel can fit on the guide rail, which is more conducive to improving the stability of the car during operation.

[0017] 2. The utility model can drive the slide to slide by rotating the stud, thereby adjusting the distance between the guide wheels, making it easier to operate during installation and maintenance. When the brake plate is engaged with the gear, the rotation of the stud can be restricted to ensure the stability between the slide and the mounting plate, making the connection between the guide wheel and the guide rail more stable.

[0029] like Figure 1-4 As shown together, the present embodiment provides a box-type elevator roller guide shoe with smooth operation. The box-type elevator roller guide shoe with smooth operation includes a mounting plate 1 and three guide wheels 2, and is characterized in that: a connecting rod 3 is rotatably connected to the guide wheel 2, and a connecting plate 4 is rotatably connected to one side of the connecting rod 3. The connecting plate 4 is mounted on the mounting plate 1, and a pulling spring 5 is connected to the end of the connecting plate 4 and the connecting rod 3 close to the guide wheel 2, and a pushing component 6 is connected to the end of the connecting plate 4 and the connecting rod 3 away from the guide wheel 2.

[0030] The pushing assembly 6 includes a pushing spring 601 , both ends of which are fixedly connected to rotating seats 602 . One rotating seat 602 is rotatably connected to the connecting rod 3 , and the other rotating seat 602 is laterally slidably arranged on the connecting plate 4 .

[0031] In the above technical solution, a plurality of mounting holes are provided on the mounting plate 1, and three guide wheels 2 are arranged in a T-shape above the mounting plate 1. The pulling spring 5 applies a pulling force to the upper end of the connecting rod 3, and at the same time, the pushing spring 602 applies a pushing force to the lower end, so that the guide wheel 2 can be tightly attached to the guide rail. The deformation direction of the pulling spring 5 and the pushing spring 602 is not perpendicular to the displacement direction of the guide wheel 2, so that the guide wheel 2 needs to use a greater force to offset the deformation force of the pulling spring 5 and the pushing spring 602 when it is displaced laterally. Therefore, the guide wheel 2 can fit more closely to the guide rail, making the operation of the car more stable.

[0032] Among them, the pulling spring 5 is in a stretched state, the pushing spring 601 is in a compressed state, and the distance from the rotation axis of the connecting rod 2 to the axis of the guide wheel 2 is smaller than the distance from the rotation axis of the connecting rod 2 to the rotating seat 602, so that the pushing spring 601 cooperates with the connecting rod 3 to form a force-saving lever. On the contrary, when the guide wheel 2 is displaced, a greater force is required to drive the connecting rod 3 to rotate, thereby making the guide wheel 2 fit more closely to the guide rail.

[0033] Both ends of the pulling spring 5 are fixedly connected with a rotating block 501 , and the two rotating blocks 501 are rotatably connected to the connecting rod 3 and the connecting plate 4 respectively.

[0034] In the above technical solution, when the connecting rod 3 rotates, the pulling spring 5 can be adaptively adjusted through the rotation cooperation of the rotating block 501.

[0035] A slide rod 603 is provided in the push spring 601 . One end of the slide rod 603 is fixedly connected to a rotating seat 602 , and the other end is slidably connected to the other rotating seat 602 .

[0036] In the above technical solution, the sliding rod 603 cooperates with the rotating seat 602 to enable the pushing spring 601 to undergo a straight displacement deformation, thereby applying a stable thrust to the connecting rod 3 .

[0037] A slider 604 is rotatably connected to a rotating seat 602 , a screw rod 605 is threadedly connected to the slider 604 , and the screw rod 605 is rotatably connected to the connecting plate 4 .

[0038] In the above technical solution, one side of the slider 604 is in sliding contact with the connecting plate 4, and rotating the screw 605 can drive the slider 604 to move, thereby adjusting the elastic force of the push spring 601 on the connecting rod 3 and improving the applicable scenario.

[0039] A slide 401 is fixedly connected to the bottom of the connecting plate 4 , and the slide 401 is slidably matched with the mounting plate 1 . A stud 402 is threadedly connected to the slide 401 , and the stud 402 is rotatably connected to the mounting plate 1 .

[0040] In the above technical solution, rotating the stud 402 can drive the slide 401 to slide, thereby adjusting the distance between the guide wheel 2 and the guide rail, which is convenient for adjustment during installation and maintenance.

[0041] One end of the stud 402 is fixedly connected to a gear 403 , and one side of the gear 403 is snap-fitted with a brake plate 404 . The end of the brake plate 404 is elastically connected to the mounting plate 1 via a brake spring 405 .

[0042] In the above technical solution, the brake spring 405 applies an upward elastic force to the brake plate 404, so that the tooth groove on the brake plate 404 is engaged with the gear 403, thereby limiting the rotation of the stud 402, so that the slide 401 is fixedly connected to the mounting plate 1, and the contact stability between the guide wheel 2 and the guide rail is improved.

[0043] When in use, install the mounting plate 1 on the car, press the brake plate 404 downward and turn the stud 402, the slide 401 moves to drive the guide wheel 2 to fit tightly against the guide rail, then release the brake plate 404 to reset it and engage with the gear 403, then turn the screw 605 to drive the slider 604 to move, so that the push spring 601 is compressed and stores force, and the push spring 601 applies a thrust to the lower end of the connecting rod 3, and at the same time pulls the spring 5 to apply a pulling force to the upper end of the connecting rod 3, so that the guide wheel 2 fits tightly against the guide rail.

[0044] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
