The plurality of the present examples refers to at least two (including two).

The lifting device mainly comprises a lifter, a hoister, an elevator and the like. For example, an elevator includes a car, and a leveling floor means an operation in which a car sill and a hoistway door sill are to be brought into the same plane when the car approaches a stop at a floor. The leveling device is used for sending out leveling control signals to enable the elevator car to level accurately. The leveling device is usually provided with an encoder and a driving wheel connected with the encoder, wherein the driving wheel can be a gear and the like, the driving wheel is connected with a driving chain and other structures of the elevator, and in the operation process of the elevator, the driving wheel synchronously rotates, and at the moment, the encoder is used for converting angular or linear displacement into an electric signal. In the lifting process of the lifting equipment, when the lifting equipment reaches a preset position, the plane height difference between the lifting device and the preset position is within a preset range. When the elevator car reaches a preset floor, the floor leveling device is used, and the surface height difference between the bottom surface of the elevator car and the corresponding floor is in a preset range.

When the floor leveling device is mounted on the lifting apparatus, the floor leveling device is typically secured to the intermediate beam of the lifting apparatus by a securing assembly. In the operation process of the lifting equipment, acting force is generated on the leveling device, so that the leveling device is easy to deviate or damage or even fall off, and the operation of the leveling device is further influenced.

The utility model provides an example of a fixing component for solving the problem that a fixing component of a leveling device is easy to move relative to a middle cross beam and even fall off from the middle cross beam, so as to solve the problem that the leveling device is unnecessarily shifted relative to the middle cross beam.

Referring to fig. 1 and 2, the fixing assembly in the example of the present utility model may be used for the leveling device 20, the fixing assembly may be used for installing and fixing the encoder assembly 21, the encoder assembly 21 includes an encoder 214, the encoder assembly 21 is connected to a gear 22 through an encoder screw 216, and when the gear 22 rotates relatively, the encoder screw 216 is driven to rotate synchronously, so that a rotation signal may be converted into an electrical signal through the encoder 214.

Referring to fig. 3, 4 and 5, the present utility model proposes an example of a fixing assembly for a leveling device 20, the fixing assembly includes a fixing body 10, a positioning member 14 and a pushing member 15, the fixing body 10 includes a mounting seat 11, and a first wall 12 and a second wall 13 disposed on the mounting seat 11, and a mounting groove 16 is formed between the mounting seat 11 and the first wall 12 and the second wall 13; the positioning piece 14 is arranged in the mounting groove 16, and the positioning piece 14 is provided with a positioning surface 141 facing the second wall 13; the pushing member 15 is connected to the first wall 12 and abuts against the positioning member 14, so that a clamping space is formed between the positioning surface 141 and the second wall 13; the pushing member 15 is movably adjustable on the first wall 12 to be able to push the positioning member 14 to move towards the second wall 13 to change the size of the clamping space.

The fixed component is used for being installed on the middle cross beam. The mounting seat 11 is a main body structure of the fixing body 10, and the mounting seat 11 may have a plate-like structure or a block-like structure. A mounting groove 16 is formed between the first wall 12 and the second wall 13, and the mounting groove 16 may be used to form a space for receiving the intermediate beam. The mounting groove 16 may be a groove formed in the mounting seat 11, and the first wall 12 and the second wall 13 may be opposite wall surfaces on the mounting groove 16. In some examples, at least one of the first wall 12 and the second wall 13 may be a plate-like structure or a block-like structure mounted on the mount 11, with a mounting groove 16 formed between the first wall 12 and the second wall 13. In some examples, the first wall 12 and the second wall 13 may be plate-like structures or block-like structures mounted on the mount 11, and at least one of the first wall 12 and the second wall 13 may be integrally provided with the mount 11, wherein the other may be integrally provided with the mount 11 or may be separately provided from the mount 11 and connected to the mount 11.

The positioning member 14 is movably disposed in the mounting slot 16 such that the positioning member 14 is movable within the mounting slot 16 between the first wall 12 and the second wall 13. The positioning member 14 has a positioning surface 141 facing the second wall 13, and a holding space for holding the intermediate beam is formed between the positioning surface 141 and the second wall 13, and when the positioning member 14 moves in a direction approaching the second wall 13, the holding space is reduced, and when the positioning member 14 moves in a direction approaching the first wall 12, the holding space is increased. The positioning member 14 may have a plate-like structure or a block-like structure, and the positioning surface 141 is a plane of the positioning member 14 facing the second wall 13.

The pushing element 15 is movably connected to the mounting seat 11 and is movably adjustable relative to the first wall 12, which means that the pushing element 15 can move relative to the first wall 12 on a fixed assembly. The pushing element 15 is movably adjusted on the first wall 12, which means that the pushing element 15 can move on the first wall 12 towards or away from the second wall 13, and the pushing element 15 can be kept at a preset position on the first wall 12 when the pushing element 15 reaches the preset position during the relative movement of the pushing element 15 on the first wall 12. The pushing member 15 can move at least partially into the mounting groove 16, so that the pushing member 15 can push the positioning member 14, so that the positioning member 14 moves in a direction approaching the second wall 13, and the clamping space formed between the positioning surface 141 and the second wall 13 is reduced.

When the fixing assembly is required to be mounted on the middle beam, the middle beam is placed in a clamping space formed between the positioning surface 141 and the second wall 13, and the positioning piece 14 is pushed by the pushing piece 15 to move towards the direction close to the second wall 13, so that the clamping space is reduced until the positioning surface 141 and the second wall 13 are abutted against the surface of the middle beam.

In this example, because the locating surface 141 and the second wall 13 are in abutting fit with the middle cross beam, and the surface contact mode is adopted, the contact area between the locating piece 14 and the second wall 13 and the middle cross beam can be increased, the contact area between the fixing component and the middle cross beam can be increased, and the connection stability of the fixing component and the middle cross beam is improved. Because the surface contact mode is adopted, after the middle cross beam is fixed in the clamping space, the direct contact surface between the middle cross beam and the fixing component is increased, so that the deflection and the inclination of the fixing component relative to the middle cross beam can be reduced, and the possibility of the deflection and the inclination of the fixing component relative to the middle cross beam can be reduced.

The locating piece 14 and the second wall 13 in this example cooperate to present the face contact mode with the middle crossbeam for the atress between different positions of middle crossbeam and locating surface 141, the second wall 13 is balanced relatively, when the installation, can conveniently carry out quick alignment and location with fixed subassembly and middle crossbeam, with the installation effectiveness that promotes fixed subassembly, and can reduce the problem of the inaccurate and relative dislocation of location of middle crossbeam and fixed subassembly.

In this example, the positioning surface 141 may be in surface contact with the middle beam, so as to increase the friction force between the positioning element 14 and the contact surface of the middle beam, and further reduce the possibility of moving the fixing component relative to the middle beam.

The pushing member 15 in this example is used for pushing the positioning member 14 to move towards the direction approaching the second wall 13, optionally, a threaded hole 121 is provided on the first wall 12, and the pushing member 15 may be a screw rod screwed to the threaded hole 121, so that the positioning member 14 may move towards the direction approaching the second wall 13 in the mounting groove 16 under the pushing of the screw rod, and when the positioning member 14 abuts against the middle beam, the positioning member 14 may be kept at a preset position under the abutting of the screw rod.

In this example, by improving the stability of the fixing component on the middle cross beam, the offset and the inclination of the fixing component relative to the middle cross beam are reduced, so that the structural stability of the leveling device 20 on the lifting equipment can be improved, and the reliability of the leveling device 20 can be improved.

Referring to fig. 4 and 5, in some examples, a slip prevention member 142 is provided on the positioning surface 141.

The anti-slip member 142 is adapted to abut between the positioning surface 141 and the intermediate beam when the intermediate beam is fixed. In the example, the anti-skid piece 142 is matched with the middle cross beam, so that the friction force between the positioning surface 141 and the middle cross beam is increased, and the possibility that the fixed component falls off from the middle cross beam is further reduced; because the friction between the two is increased, the fixed component is not easy to deviate and incline relative to the middle cross beam, and the stability of the fixed component can be improved.

Alternatively, the anti-skid member 142 in this example may be a rubber pad or other cushion structure having elastic anti-skid properties.

The number of the anti-skid members 142 in this example may be one, or the number of the anti-skid members 142 may be a plurality of the anti-skid members distributed on the positioning surface 141 according to a predetermined rule.

Optionally, the anti-skid member 142 is detachably coupled to the positioning member 14 to facilitate the disassembly and replacement of the anti-skid member 142 when needed. Optionally, a fixing groove 142a is provided on the anti-slip member 142, and the anti-slip member 142 is connected to the positioning member 14 by a screw or the like penetrating the fixing groove 142 a.

Referring to fig. 4 and 5, in some examples, one of the first wall 12 and the positioning member 14 is provided with a guide hole 122, and the other is provided with a guide post 143, and the guide post 143 is disposed through the guide hole 122.

The guide hole 122 in this example is mated with the guide column 143, and the guide column 143 is movable within the guide hole 122 along the axial direction of the guide hole 122. The direction of movement of the guide posts 143 within the guide holes 122 coincides with the direction of movement of the positioning member 14. Optionally, a guide hole 122 is formed in the first wall 12, and a guide post 143 is provided on the positioning member 14. Optionally, the guide hole 122 is provided on the positioning member 14, and the guide post 143 is provided on the first wall 12. Optionally, the first wall 12 and the positioning member 14 are respectively provided with a guide hole 122 and a guide column 143, the guide column 143 on the positioning member 14 is disposed through the guide hole 122 on the first wall 12, and the guide column 143 on the first wall 12 is disposed through the guide hole 122 on the positioning member 14, so that the guide column 143 can be mutually matched with the guide hole 122 in a positioning manner, and the positioning member 14 can only move along the preset direction. Alternatively, the guide hole 122 in this example is a circular hole, the guide column 143 is a cylindrical structure, and the axis of the guide column 143 may coincide with the axis of the guide hole 122. Further alternatively, the first wall 12 is provided with a threaded hole 121 as described in the above example, and the axis of the guide hole 122 is parallel to the axis of the threaded hole 121.

In this example, due to the limitation of the guide hole 122, the guide column 143 can only move along the direction approaching or separating from the second wall 13, and the movement track of the corresponding positioning element 14 is limited, so that the positioning element 14 can maintain the preset movement track, and the inclination generated by the positioning element 14 is reduced; further, since the positioning member 14 can move along the preset track, the problem that the positioning member 14 is inclined relative to the second wall 13 due to uneven force of the pushing member on different parts of the positioning member 14 can be reduced, so that the positioning member 14 can be in surface fit with the middle cross beam through the positioning surface 141, and further the effectiveness and stability of the fit of the positioning surface 141 and the middle cross beam can be improved.

In some examples, the first wall 12 is detachably connected with the mount 11. The first wall 12 in this example may have a flat plate structure, and the first wall 12 may also have a block structure, where the first wall 12 is detachably connected to the mounting seat 11, that is, the first wall 12 and the mounting seat 11 are respectively formed and then mounted to each other. By adopting the detachable connection mode, the first wall 12 and the mounting seat 11 can be respectively formed, so that the processing performance of the fixing assembly is improved.

In some examples, the second wall 13 is integrally provided with the mount 11. The second wall 13 in this example may be integrally molded with the mount 11, or the end of the mount 11 may be bent to form the second wall 13. By adopting the integrally provided second wall 13, the reliability of the connection of the second wall 13 and the mount 11 can be improved, and at the same time, the processing efficiency of the mount 11 and the second wall 13 can be improved.

In some examples, the first wall 12 is detachably connected with the mount 11, and the second wall 13 is integrally provided with the mount 11.

The present utility model also proposes an example of a leveling device 20 for a lifting apparatus on the basis of the above-described fixing assembly, the leveling device 20 comprising the fixing assembly, the encoder assembly 21 and the gear 22 as in any of the above examples; the encoder assembly 21 is mounted to the mounting block 11 of the fixed assembly; the gear 22 is connected to the encoder assembly 21 by an encoder screw 216.

The encoder screw 216 in this example is rotatable relative to the encoder assembly 21, the encoder screw 216 being an intermediate connection of the encoder assembly 21 and the gear 22 to transmit rotation of the gear 22 to the encoder assembly 21. The encoder assembly 21 obtains a flat layer signal by converting the rotational signal of the gear 22 into an electrical signal.

In this example, the encoder assembly 21 is installed by adopting the fixing assembly, and after the fixing assembly is installed on the middle beam, the connection stability of the fixing assembly and the middle beam is higher, so that the stability of the encoder assembly 21 is relatively higher, and the problem of detection defects caused by offset or inclination of the encoder assembly 21 can be reduced.

In some examples, the leveling device 20 further includes a spring 24 connected between the encoder lead screw 216 and the gear 22.

The spring 24 in this example acts as an intermediate connection between the encoder screw 216 and the gear 22 for transmitting rotation of the gear 22 to the encoder screw 216. Alternatively, the gear 22 in this example may further include a gear fixing screw 221, and an end of the spring 24 remote from the encoder screw 216 may be connected to the gear fixing screw 221.

In this example, by adopting the spring 24 structure, a certain deformation allowance can be formed between the gear 22 and the encoder screw 216, and during the operation process of the lifting device, the acting force applied to the gear 22 can be compensated by the spring 24, so as to reduce the damage of the gear 22, the encoder assembly 21, the encoder screw 216 and the like caused by the instant acting force.

In some examples, the encoder screw 216 is provided with a stiffening tube 217, and the spring 24 is disposed through the stiffening tube 217 near one end of the encoder screw 216.

The reinforcement tube 217 in this example is a hollow tubular structure, and the reinforcement tube 217 is sleeved on the periphery of the spring 24 to limit the radial deformation range of the spring 24. The reinforcement tube 217 is connected with the encoder screw 216, so that the reinforcement tube 217 is disposed at one end of the spring 24 close to the encoder screw 216, and limits the radial deformation range of the spring 24 at one end of the spring 24 close to the encoder screw 216, thereby improving the structural reliability of the spring 24 and reducing the influence on the axial deformation range of the spring 24. Optionally, in this example, the axial length of stiffening tube 217 is less than the length of spring 24 in the maximally contracted state.

In some examples, encoder assembly 21 includes a housing 211 and an encoder 214, housing 211 being mounted to mount 11, housing 211 defining a mounting cavity (not shown); the encoder 214 is disposed in the mounting cavity, and an end of the encoder screw 216 remote from the gear 22 is connected to the encoder 214.

The housing 211 in this example is used to form a mounting cavity for mounting the encoder 214 to protect the encoder 214. The housing 211 is coupled to the mounting block 11 to secure the encoder assembly 21 to the stationary assembly.

The encoder 214 is coupled to an encoder screw 216 such that rotation of the gear 22 can be transmitted to the encoder 214 via the encoder screw 216. The encoder 214 converts the rotation signal into an electrical signal. Taking the example of the leveling device 20 for an elevator, the encoders of the elevator can be divided into two types according to the working principle: incremental encoders and absolute encoders. The incremental elevator encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into counting pulses, the number of pulses representing the magnitude of the displacement. Since each position of the absolute elevator encoder corresponds to a specific numerical code, its display refers only to the beginning and ending positions of the measurement, not to the middle of the measurement. The encoder 214 in this example may also select a known encoder 214 structure according to a specific usage scenario, which will not be described in detail.

Referring to fig. 2, in some examples, a bearing 215 is disposed on the housing 211, and an encoder screw 216 is connected to the bearing 215.

The bearing 215 in this example is fixedly attached to the housing 211 such that the bearing 215 can be fixed relative to the housing 211. The encoder screw 216 and the rotation shaft of the encoder 214 are respectively connected to the inner ring of the bearing 215 so that the rotation of the encoder screw 216 can be transmitted to the encoder screw 216. By providing the bearing 215 structure in this example, support can be provided to the encoder screw 216 to promote stability of the encoder screw 216 and reduce radial displacement generated by the encoder screw 216.

Referring to fig. 2, in some examples, a side of the chassis 211 near the mounting seat 11 is provided with a first avoidance hole 212a that communicates with the mounting cavity.

The housing 211 in this example may be used to prevent contamination of the encoder 214 by materials such as liquids. Because the first avoidance hole 212a is arranged on one side of the chassis 211, which is close to the mounting seat 11, the first avoidance hole 212a can be shielded by the chassis 211, so that the structures such as wires required by the encoder 214 can be led out through the first avoidance hole 212a conveniently, the additional arrangement of a protection structure at the position where the wires are arranged on the encoder 214 is not required, and the waterproof structure such as a waterproof connector is not required to be arranged on the encoder 214, so that the structure of the encoder assembly 21 is simplified, and the whole volume of the encoder assembly 21 is reduced.

Referring to fig. 2, 3 and 4, in some examples, the mounting seat 11 has a second avoidance hole 111 corresponding to the position of the first avoidance hole 212a.

The second dodges the hole 111 in this example and the position of first dodges the hole 212a corresponding to make structures such as wire follow first dodge the hole 212a output after, can dodge the hole 111 by the second, and then can play the guard action to the wire through mount pad 11, reduce the possibility that the wire received the damage. In this example, since the wire structure can be output through the second avoidance hole 111, the area of the assembly surface of the mounting seat 11 and the chassis 211 can be close, and then the contact area of the connection part of the mounting seat 11 and the chassis 211 is correspondingly increased, so as to improve the reliability of the connection part of the chassis 211 and the mounting seat 11.

In some examples, the chassis 211 includes a base 212 and a cover 213 disposed on a side of the base 212 facing away from the mounting base 11, the base 212 and the cover 213 enclosing a mounting cavity; the base 212 is connected to the mount 11 via a connector 23, and the connector 23 is provided outside the cover 213.

The base 212 in this example is mated with the cover 213 to form a mounting cavity, the encoder 214 is mounted in the mounting cavity, and the encoder 214 can be connected and fixed with the base 212. The base 212 is used for connecting with the mounting seat 11. The connecting piece 23 in this example is used to connect and fix the base 212 and the mounting seat 11 to each other, and the connecting piece 23 may be a bolt or the like. Since the connector 23 is disposed outside the cover 213 in this example, the cover 213 may not be opened when the chassis 211 is detached, and the base 212 may be directly detached from the mounting base 11, so that the detachment and attachment can be simplified, and the detachment and attachment efficiency can be improved.

It should be noted that, since the example of the leveling device 20 of the present utility model is based on the example of the fixing component, the example of the leveling device 20 of the present utility model includes all the technical solutions of all the examples of the fixing component, and the achieved technical effects are identical, and will not be described herein.
