Description

Technical Field

[0001] This utility model relates to the field of elevator safety clamp technology, and in particular to an elevator safety clamp with guide rail repair function. Background Technology

[0002] Elevator safety brakes are crucial equipment for ensuring the safe operation of elevators. When an elevator experiences unexpected overspeeding or a fall, the safety brake activates its braking mechanism, firmly stopping the elevator on the guide rails and ensuring the safety of the equipment and personnel. However, existing safety brakes typically achieve braking through the friction between a brake wedge and the guide rails. To increase the coefficient of friction between the brake wedge and the guide rails, the surface of the brake wedge is often knurled or grooved to increase its surface roughness, and it also undergoes surface hardening treatment to improve its wear resistance.

[0003] However, because the brake wedge is usually harder than the guide rail, it creates uneven braking marks on the guide rail surface during braking. When the guide shoe slides over these uneven guide rail surfaces, it can severely damage the guide shoe liner, thus affecting the comfort of elevator operation. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an elevator safety clamp with guide rail repair function, which has the advantage of being able to repair the guide rail surface while the safety clamp is braking.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An elevator safety clamp with guide rail repair function, comprising:

[0007] The clamp base has a mounting cavity;

[0008] A braking assembly, wherein the braking assembly is disposed in the mounting cavity and connected to the caliper seat;

[0009] A repair component is disposed above and connected to the braking component, and is used to repair damage to the surface of the guide rail.

[0010] Compared to existing technologies, this application provides a repair component above the braking assembly for repairing damage to the guide rail surface. This allows the guide rail surface to be repaired during the braking process of the safety clamp, reducing the impact of braking marks on the guide shoes and elevator operating comfort, and improving the safety and comfort of elevator operation.

[0011] As a preferred embodiment of this utility model, the braking assembly includes:

[0012] Two guide blocks are disposed opposite each other in the mounting cavity and movably connected to the clamp seat, and a guide rail is located between the two guide blocks;

[0013] Braking wedges, each of the guide blocks is provided with a braking wedge;

[0014] The repair component is disposed above the brake wedge and connected to the brake wedge.

[0015] By adopting the above scheme, the guide block setting can ensure that the brake wedge can accurately brake the guide rail. At the same time, the repair component is set above the brake wedge, which can simultaneously repair the guide rail during the braking process. This effectively avoids the problem that the guide shoe liner will be seriously damaged when the guide shoe slides on the guide rail due to the grooves generated after braking.

[0016] As a preferred embodiment of this utility model, the repair component includes:

[0017] A repair seat is disposed on the top wall of the brake wedge;

[0018] A repair block is disposed between the guide rail and the repair seat;

[0019] A pre-tightening adjustment component is disposed on the repair seat and connected to the repair block, and the pre-tightening adjustment component is used to adjust the distance between the repair block and the repair seat.

[0020] Using the above solution, the repair block can fit tightly against the guide rail surface under the action of the pre-tightening adjustment component. At the same time, the distance between the repair block and the repair seat can be adjusted under the action of the pre-tightening adjustment component, which can ensure that the repair block can still maintain sufficient repair pressure after wear and guarantee the repair effect.

[0021] As a preferred embodiment of this utility model, the pre-tightening adjustment component includes:

[0022] An adjusting bolt, which passes through the repair seat and is connected to the repair block;

[0023] A pre-tightening member is disposed between the repair seat and the repair block, and is connected to both the repair seat and the repair block respectively.

[0024] By adopting the above solution, the pressure of the repair block on the guide rail can be adjusted by adjusting the setting of the bolts and preload. When the repair block wears, the pressure can be increased by adjusting the bolts to ensure that the repair capability does not decrease and to extend the service life of the repair component.

[0025] As a preferred embodiment of this utility model, the repair seat is provided with a through hole, and the adjusting bolt passes through the through hole and is threadedly connected to the repair block.

[0026] Using the above solution, the adjusting bolt can pass smoothly through the through hole to the repair seat and connect with the repair block to adjust the pressure of the repair block. At the same time, the threaded connection ensures the stability and reliability of the adjustment.

[0027] As a preferred embodiment of this utility model, the repair seat is provided with a receiving groove on the side near the repair block, and the pre-tightening member is located in the receiving groove and is connected to the repair seat and the repair block respectively.

[0028] By adopting the above solution, the design of the receiving groove provides installation space for the pre-tightening component, allowing it to be tightly connected between the repair seat and the repair block, ensuring effective transmission of the pre-tightening force and improving the repair effect.

[0029] As a preferred embodiment of this utility model, the pre-tightening component includes a pressure spring, which is sleeved on the adjusting bolt, and the two ends of the pressure spring are respectively connected to the repair seat and the repair block in contact.

[0030] Using the above solution, the pressure spring, as a preload element, can provide a stable preload force. When the repair block wears, the pressure spring can automatically compensate for the pressure drop, maintaining the effective repair function of the repair block on the guide rail.

[0031] As a preferred embodiment of the present invention, the clamp base includes a base plate and a top plate, and at least two side plates are provided between the base plate and the top plate. The side plates are respectively connected to the top plate and the base plate, and an installation cavity is formed between the top plate and the base plate.

[0032] As a preferred embodiment of this utility model, both the top plate and the bottom plate are provided with openings for the guide rail to pass through.

[0033] The elevator safety clamp with guide rail repair function described above has the following beneficial effects:

[0034] By setting a repair component in the elevator safety clamp, the repair block with adjustable preload can simultaneously repair the damage to the guide rail surface during the braking process of the brake wedge. This effectively solves the problem of uneven grooves on the guide rail caused by traditional safety clamp braking, reduces the impact of brake marks on the guide shoes and elevator running comfort, improves the safety and comfort of elevator operation, and extends the service life of the repair component, ensuring the stability and reliability of the repair effect.

[0045] This utility model proposes an elevator safety clamp with guide rail repair function.

[0046] Reference Figure 1 and Figure 2 In one embodiment of this utility model, an elevator safety clamp with guide rail repair function includes: a clamp seat 1, a braking component 2, and a repair component 3. The clamp seat 1 includes a base plate 11 and a top plate 12. Two side plates 13 are disposed between the base plate 11 and the top plate 12, and the side plates 13 are fixedly connected to the top plate 12 and the base plate 11 respectively. An installation cavity 4 is formed between the top plate 12 and the base plate 11. Both the top plate 12 and the base plate 11 have openings 14 for the guide rail to pass through. The braking component 2 is disposed in the installation cavity 4 and connected to the clamp seat 1. The repair component 3 is disposed above the braking component 2 and connected to the braking component 2. The repair component 3 is used to repair damage to the surface of the guide rail. By providing a repair component above the braking component 2 for repairing damage to the surface of the guide rail, the surface of the guide rail can be repaired during the braking process of the safety clamp, reducing the impact of braking marks on the guide shoes and the comfort of elevator operation, and improving the safety and comfort of elevator operation.

[0047] Reference Figures 1 to 3In one embodiment, the braking assembly 2 includes two guide blocks 21 and a brake wedge 22. The two guide blocks 21 are disposed opposite each other in the mounting cavity 4 and movably connected to the caliper seat 1. A guide rail is located between the two guide blocks 21. Specifically, the top plate 12 and the bottom plate 11 are each provided with a sliding groove on their opposite sides. The guide blocks 21 are slidably disposed on the top plate 12 and the bottom plate 11 through the sliding groove. A brake wedge 22 is fixedly connected to each guide block 21. The brake wedge 22 can be fixedly installed on the guide block 21 by bolts. In this embodiment, one brake wedge 22 is fixedly disposed on each guide block 21, and the side of the brake wedge 22 near the guide rail is provided with multiple brake grooves. The repair assembly 3 is disposed above the brake wedge 22 and connected to the brake wedge 22. In other embodiments, the number of brake wedges 22 can be increased according to actual needs. The number of brake wedges 22 is not limited here. It is worth noting that the guide block 21 can slide along the sliding groove under the action of the external drive device, so that the brake wedge 22 contacts the guide rail to achieve the braking effect. Since this application does not involve the improvement of the drive device, and the drive device is not within the protection scope of this application, the specific structure of the drive device will not be described in detail. The setting of the guide block 21 can ensure that the brake wedge 22 can accurately brake the guide rail. At the same time, the repair component 3 is set above the brake wedge 22, which can simultaneously repair the guide rail during the braking process, effectively avoiding the problem that the guide shoe liner will be seriously damaged when the guide shoe slides on the guide rail due to the grooves generated after braking.

[0048] Reference Figures 3 to 5In one embodiment, the repair assembly 3 includes a repair seat 31, a repair block 32, and a pre-tightening adjustment assembly 33. The repair seat 31 is bolted to the top wall of the brake wedge 22; the repair block 32 is located between the guide rail and the repair seat 31; the pre-tightening adjustment assembly 33 is mounted on the repair seat 31 and connected to the repair block 32, and is used to adjust the distance between the repair block 32 and the repair seat 31. The pre-tightening adjustment assembly 33 includes an adjusting bolt 331 and a pre-tightening element 332. The repair seat 31 has a through hole 34, and... The repair seat 31 has a receiving groove 35 on its side near the repair block 32 to accommodate the pre-tightening member 332. The position of the receiving groove 35 corresponds to the through hole 34. The adjusting bolt 331 passes through the through hole 34 and is threadedly connected to the repair block 32. The pre-tightening member 332 is located in the receiving groove 35 and abuts against both the repair seat 31 and the repair block 32. In this embodiment, a pressure spring is used as the pre-tightening member 332. The pressure spring is sleeved on the adjusting bolt 331, and its two ends abut against both the repair seat 31 and the repair block 32. By using the combination design of the adjusting bolt 331 and the pre-tightening member 332, the pressure of the repair block 32 on the guide rail is adjustable. When the pressure of the repair block 32 on the guide rail decreases due to wear, the pressure of the repair block 32 on the guide rail can be increased by adjusting the bolt 331. At the same time, the pressure spring can automatically compensate for the pressure loss, ensuring that the repair block 32 always maintains an effective repair function on the guide rail, thereby ensuring the stability of the repair capability and the reliability of the repair effect, and extending the service life of the repair assembly 3.

[0049] By setting the repair component 3 in the elevator safety clamp, the repair block 32 with adjustable preload can simultaneously repair the damage to the guide rail surface during the braking process of the brake wedge block 22. This effectively solves the problem of uneven grooves on the guide rail caused by the traditional safety clamp during braking, reduces the impact of brake marks on the guide shoe and elevator running comfort, improves the safety and comfort of elevator operation, and extends the service life of the repair component 3, ensuring the stability and reliability of the repair effect.
