Description

Technical Field

[0001] This invention relates to the field of elevator wheel processing technology, and in particular to an elevator wheel surface finishing device. Background Technology

[0002] Traditional traction wheel processing clamping mechanisms often use a single fixed mode, which is difficult to adapt to different types of traction wheels, resulting in poor equipment versatility. Furthermore, when facing the same type of traction wheel, the size and position distribution of the fixing holes on the surface of the traction wheel are different, leading to incompatible clamping and unstable grinding process.

[0003] Prior art document CN114770254B discloses an elevator wheel surface finishing device and process, including a support frame, a fixing plate, a rotary table, a quick-lock device, and a grinding component. This invention solves the main problems in the current elevator traction wheel processing, such as the presence of burrs, sharp corners, and other metal residues on the edges of the traction wheel after turning, which pose safety risks to operators and can cut the rope, affecting its service life. Furthermore, the current method of fixing the traction wheel by moving an inner diameter chuck outward to abut against the inner wall of the traction disc limits the traction wheel's freedom of movement, lacks stability, and is prone to tilting and shifting during clamping, resulting in significant parallelism errors after secondary clamping.

[0004] In actual use, the above-mentioned device is only suitable for a single type of traction wheel and not for different types of traction wheels. Furthermore, the size and position distribution of the fixing holes on the surface of the traction wheel are different, resulting in incompatible clamping and unstable grinding process. Summary of the Invention

[0011] Furthermore, the end of the first grinding block facing the circular groove of the auxiliary gear seat is connected to an elastic grinding block with a U-shaped groove, which is used to guide large particles of waste through; the second grinding block is connected to a straight auxiliary grinding block on the opposite side of the first grinding block, and the straight auxiliary grinding block is adapted to the elastic grinding block with a U-shaped groove; the two sides of the elastic grinding block and the auxiliary grinding block are arc-shaped, which is used to guide the grinding waste.

[0012] Furthermore, the elastic grinding block has two internal bladders fixed at both ends, and one end of the bladder is equipped with a connecting valve for adjusting the size of the elastic grinding block to fit different sizes of wheel grooves; an electrostatic generator is fixed inside the first shell, and a collection chamber is opened at the lower end of the U-shaped groove of the bladder; a diaphragm is fixed inside the collection chamber, forming an internal cavity through the diaphragm; electrostatic adsorption powder is placed inside the internal cavity, and the material of the electrostatic adsorption powder is polytetrafluoroethylene (PTFE) powder; the electrostatic generator generates static electricity on the electrostatic adsorption powder, attracting the fine and large particles of waste debris produced by grinding (the commonly used materials for traction wheels are ductile iron, cast steel, and alloy steel).

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0031] Example 1

[0032] Please see Figures 1 to 4This invention provides an elevator wheel surface finishing device, including a base 100 and a traction wheel. The traction wheel is divided into a traction wheel A with an A column and an A ring, and a traction wheel B with a B ring. The surface of the B ring is provided with a fixing hole in the circumferential direction. A herringbone groove is opened on the upper part of the base 100. Two mutually meshing main gears 110 and secondary gear seats 120 are rotatably connected to the base 100. The main gears 110 are driven by a motor. The base 100 is also provided with three sets of clamping assemblies 200. The clamping assembly 200 includes a hydraulic cylinder 202 that drives the connecting block 201. The connecting block 201 is provided with a clamping member 204 for clamping traction wheel A or traction wheel B. The clamping member 204 is provided with a clamping member 205 for clamping traction wheel B, a telescopic rod 206 and a fixing rod 207. The secondary gear seat 120 is provided with a grinding assembly 210 for grinding the traction wheel groove.

[0033] The auxiliary gear seat 120 has a through groove in the middle, and a herringbone groove is located in the through groove. Three sets of clamping components 200 are located in the herringbone groove. The hydraulic cylinder 202 is fixed in one side of the herringbone groove, and the connecting block 201 is fixed in the output end of the hydraulic cylinder 202. The second clamp 203 is used to clamp the traction wheel A. The second clamp 203 is symmetrically rotated and connected to both sides of one end of the connecting block 201. The first clamp 204 is fixed in the upper part of its other end. The surface of the second clamp 203 that contacts the A-pillar is provided with an elastic element 2031, which is used to clamp and adapt to the curvature of the A-pillar.

[0034] The clamp 3 205 is rotatably connected to the clamp 1 204, the telescopic rod 206 is slidably connected inside the clamp 3 205, and the fixing rod 207 is slidably connected to one end of the telescopic rod 206; the fixing rod 207 is used to fix the fixing hole on the surface of ring B to prevent the traction wheel B from rotating during the grinding process of the grinding assembly 210.

[0035] The grinding assembly 210 includes a first shell 211 and a second shell 212 arranged symmetrically. The first shell 211 has a first grinding block 2111 on one end face facing the circular groove of the auxiliary gear seat 120, and the second shell 212 has a second grinding block 2121 on one end face opposite to the first grinding block 2111. The two opposing first grinding blocks 2111 and second grinding blocks 2121 grind together, which improves the grinding efficiency.

[0036] Specific implementation: When grinding traction wheel A, firstly, extend the hydraulic cylinders 202 of the three sets of clamping components 200 to their maximum distance. Then, pass the A-ring of traction wheel A through clamp 1 204 and place it into the through groove of the auxiliary gear seat 120. Then, retract the hydraulic cylinders 202 to clamp the A-ring with clamp 1 204. Finally, rotate clamp 203 to clamp the A-column of traction wheel A with elastic element 2031. When grinding traction wheel B, similarly, extend the hydraulic cylinders 202 of the three sets of clamping components 200 to their maximum distance, then pass the B-ring of traction wheel B through... The clamp 204 is placed into the through groove of the auxiliary gear seat 120. The hydraulic cylinder 202 retracts to clamp the B ring with the clamp 204. Finally, the clamp 205 is rotated to be flush with the surface of the traction wheel B. The telescopic rod 206 is pulled out from the clamp 205 until the fixing rod 207 can enter the fixing hole on the surface of the B ring. After fixing, the electric motor is started to drive the main gear 110 to rotate. The rotation of the main gear 110 drives the auxiliary gear seat 120 to rotate, so that the grinding assembly 210 rotates to perform fine grinding on the groove of the traction wheel.

[0037] Example 2

[0038] When the A-pillar of the traction sheave A is contaminated with oil, or when the elastic element 2031 and clamping element 204 are contaminated with oil, the traction sheave A will tend to rotate during the grinding process of the grinding assembly 210, and the traction sheave A may shift upwards. This application proposes the following technical solution to address the above-mentioned technical problem:

[0039] Please see Figure 5 and Figure 6 This invention provides an elevator wheel surface finishing device. The clamping member 203 includes a connecting belt 208, one of which has an inverted T-shaped groove. One end of the connecting belt 208 is fixed to another clamping member 203, and the other end is engaged in the inverted T-shaped groove of the other clamping member 203. A bladder 209 with an inflation port is also fixed to the connecting belt 208. The bladder 209 is inflated and compressed by the connecting belt 208 passing around the A-pillar to prevent the traction wheel A from shifting upward.

[0040] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0041] By using the connecting belt 208 to bypass the A-pillar, the bladder 209 is inflated and expanded, surrounding and compressing the upper surface of the A-pillar to prevent the traction wheel A from shifting upwards during the grinding process, thus improving the stability of the grinding process.

[0042] Example 3

[0043] When grinding the grooves of the traction sheave, large particles ground by the first grinding block 2111 and the second grinding block 2121 may cause secondary crushing, resulting in indentations inside the grooves. This application proposes the following technical solution to address the above-mentioned technical problem:

[0044] Please see Figures 7 to 8 This invention provides a surface finishing device for elevator wheels. The first grinding block 2111 has an elastic grinding block 2112 with a U-shaped groove at one end facing the circular groove of the auxiliary gear seat 120, which is used to guide large particles of waste through. The auxiliary grinding block 2122 has a straight auxiliary grinding block 2122 on its opposite side to the first grinding block 2111, and the straight auxiliary grinding block 2122 is adapted to the elastic grinding block 2112 with the U-shaped groove. The two sides of the elastic grinding block 2112 and the auxiliary grinding block 2122 are arc-shaped to guide the grinding waste.

[0045] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0046] During the grinding process, large particles are guided by the arc-shaped side of the elastic grinding block 2112 and slide out from the U-shaped groove of the elastic grinding block 2112. This not only improves the stability of the grinding process, but also prevents large particles from accumulating on the side of the first grinding block 2111 and causing indentations in the wheel groove due to secondary crushing.

[0047] Example 4

[0048] Fine debris generated during grinding tends to accumulate in the wheel groove, potentially affecting the stability and quality of the grinding process. This application addresses the aforementioned technical problem by proposing the following technical solution:

[0049] Please see Figure 9 and Figure 10 This invention provides a device for finishing the surface of an elevator wheel. The elastic grinding block 2112 has two internal bladders 221 fixed at both ends, and one end of each bladder 221 has a connecting valve 222 for adjusting the size of the elastic grinding block 2112 to fit different wheel groove sizes. An electrostatic generator 220 is fixed inside the first shell 211. A collection cavity 223 is opened at the lower end of the U-shaped groove of the bladder 221. A diaphragm 224 is fixed inside the collection cavity 223, forming an internal cavity 2241 within the collection cavity 223. Electrostatic adsorption powder 225, made of polytetrafluoroethylene (PTFE), is placed inside the internal cavity 2241. The electrostatic generator 220 generates static electricity on the electrostatic adsorption powder 225, attracting fine and large particles of waste debris (common materials for traction wheels are ductile iron, cast steel, and alloy steel).

[0050] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0051] The electrostatic generator 220 generates static electricity on the electrostatically adsorbed powder 225. When fine and large particles of waste debris pass through, they are attracted by static electricity and fall into the collection chamber 223. This improves the stability of the grinding process and prevents waste debris from accumulating and flying around.

[0052] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0053] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
