[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0045] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0046] Example 1:

[0047] like Figure 1 、 2 As shown, the present invention provides a multi-wheel rolling guide shoe using independent shock-absorbing rollers, comprising:

[0048] A guide shoe seat 1, the top of which is connected to a guide shoe bracket 2;

[0049] Roller seats 3, three roller seats 3 are detachably connected to the guide shoe bracket 2, and the three roller seats 3 are arranged in a herringbone shape when viewed from above;

[0050] Shock-absorbing rollers 4, three shock-absorbing rollers 4 are arranged on the roller seat 3 in the vertical direction, and the shock-absorbing rollers 4 on the three roller seats 3 have corresponding heights, and elastic members are arranged between the shock-absorbing rollers 4 and the roller seat 3;

[0051] The vibration monitoring unit is provided on the roller seat 3 and is used to detect the vibration condition of the connection between the shock-absorbing roller 4 and the roller seat 3. The controller activates the alarm unit according to the detection result of the vibration monitoring unit.

[0052] The working principle and beneficial effects of the above technical solution are:

[0053] The present invention provides a multi-row rolling guide shoe utilizing independent shock-absorbing rollers. Three roller seats 3 are disposed on a guide shoe support 1, arranged in a herringbone pattern. Three shock-absorbing rollers 4 are vertically disposed on the roller seats 3, with elastic members disposed between each shock-absorbing roller 4 and the roller seats 3. When the rolling guide shoe is in use, the guide shoe support 2 slides along a guide rail. The three shock-absorbing rollers 4 at the same height, acting under the action of the elastic members, clamp the guide rail within them, providing shock absorption and guidance in all directions at the same height. The elastic members can employ the structure of elastic assemblies known in the art. The three rollers 4 arranged vertically on the roller seats 3 provide shock absorption and balance for the upper and lower portions of the same side of the guide rail. A vibration monitoring unit is provided on the roller seat 3 to detect the vibration amplitude of the roller seat 3; when the shock-absorbing roller is effectively used, the vibration wave will be weakened to a preset range through the action of the elastic member; when the vibration amplitude detected by the vibration detection unit is greater than the preset value, it indicates that the shock-absorbing effect of the shock-absorbing roller 4 has failed, and the shock-absorbing roller 4 may be worn or loose in connection, and the alarm unit is activated to prompt the user to perform maintenance.

[0054] Through the above-mentioned structural design, each shock-absorbing roller 4 is provided with an independent elastic part, and a multi-row T-shaped layout is adopted to improve the stable guidance and sufficient shock absorption during the operation of the elevator; a detachable roller seat 3 is adopted to integrate the shock-absorbing roller 4 on the same side on the roller seat 3, and the shock-absorbing roller 4 on the same side can be disassembled and replaced at the same time during maintenance, which better adapts to the situation where the shock-absorbing roller 4 on one side wears synchronously when the center of gravity of the elevator is unbalanced, thereby improving maintenance efficiency and greatly reducing the elevator downtime.

[0055] Example 2:

[0056] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1, a guide rail groove 5 is provided in the center of the guide shoe bracket 2, the shock-absorbing rollers 4 on both sides protrude from the left and right side walls of the guide rail groove 5, the rear shock-absorbing roller 4 protrudes from the rear side wall of the guide rail groove 5, and the guide rail is slidably provided in the guide rail groove 5 and abuts against the shock-absorbing roller 4.

[0057] The working principle and beneficial effects of the above technical solution are:

[0058] A guide rail groove 5 is provided on the guide shoe bracket 2. When the rolling guide shoe moves along the guide rail, the guide rail and the guide rail groove 5 slide relative to each other, guiding the operation of the rolling guide shoe. The combined shock-absorbing roller 4 abuts against the guide rail. When the rolling guide shoe moves to a position where the assembly and structure of the guide rail and the guide rail groove 5 deviate, the movement flexibility of the rolling guide shoe is improved, the vibration between the guide rail and the guide rail groove 5 is reduced, and the operation noise is reduced.

[0059] Example 3:

[0060] like Figure 3-Figure 7As shown, on the basis of the above-mentioned embodiment 1, a magnetic positioning frame 11 is provided on the side of the roller seat 3, the magnetic positioning frame 11 is provided as an L-shaped frame and is connected with reinforcing ribs at the corners, and a magnetic block is pre-embedded in the horizontal section of the magnetic positioning frame 11; a first slide groove 12 is provided on the side of the guide shoe bracket 2, the first slide groove 12 passes through the rear side of the guide shoe bracket 2, and a magnetic strip 13 is provided on the outside of the first slide groove 12. The magnetic positioning frame 11 is slidably provided in the first slide groove 12, and the magnetic strip 13 attracts the magnetic positioning frame 11.

[0061] The working principle and beneficial effects of the above technical solution are:

[0062] When installing the roller seat 3, the horizontal section of the magnetic positioning frame 11 is aligned with the first slide groove 12 and inserted from the back side to the front side. The magnetic positioning frame 11 slides from the back to the front along the first slide groove 12 until it reaches the preset installation position. The first slide groove 12 limits the vertical position of the magnetic positioning frame 11; the magnetic positioning frame 11 is attracted by the magnetic strip 13 to ensure that the magnetic positioning frame 11 can move flexibly without being separated from the first slide groove 12, thereby ensuring the installation stability of the roller seat 3.

[0063] Example 4:

[0064] like Figure 3-Figure 7 As shown, based on the above embodiment 3, a positioning unit is provided at the center of the roller seat 3, and the positioning unit includes:

[0065] The linkage member 14 is rotatably connected to the transmission groove 15 on the outside of the guide shoe bracket 2. The bottom of the transmission groove 15 is provided with a corner for limiting the rotation angle of one end of the linkage member 14. The other end of the linkage member 14 is provided near the roller seat 3 and is penetrated by a plug hole 16. A vibration monitoring unit is provided on the linkage member 14.

[0066] The positioning block 17 is connected to the side of the roller seat 3. The front side of the positioning block 17 is connected to the plug-in column 18. The plug-in column 18 is slidably connected to the plug-in hole 16. The positioning block 17 is provided with a limiting member connected to the linkage member 14. The limiting member is used to limit the front and rear positions of the roller seat 3.

[0067] The working principle and beneficial effects of the above technical solution are:

[0068] When the roller seat 3 is not installed, the linkage member 14 can be rotated and stored in the transmission groove 15, which is convenient for component transportation.

[0069] When the roller seat 3 is installed, the linkage 14 is rotated so that one end of the plug hole 16 is extended out of the transmission groove 15, and the other end is rotated to contact the corner of the transmission groove 15, so that the linkage 14 is rotated to a preset angle; as the magnetic positioning frame 11 slides, the plug-in column 18 is installed in the plug-in hole 16, and the positioning block 17 is limited, thereby limiting the horizontal direction of the magnetic positioning frame 11, so that the magnetic positioning frame 11 cannot slide out from the side of the first slide groove 12; a limiting member is provided on the positioning block 17, and the limiting member can be provided as a pluggable structure such as a pin or a rod. After the limiting member is installed, it is engaged with the limiting hole on the linkage 14, thereby limiting the front and rear position of the roller seat 3 and limiting the rotation of the linkage 14.

[0070] When the roller seat 3 is disassembled, the limiting member is pulled out from the positioning block 17 and the roller seat 3 is slid out in the opposite direction.

[0071] Through the above-mentioned structural design, the roller seat 3 adopts a combined plug-in structure during installation, and is accurately positioned in the horizontal, vertical and rotational directions to ensure that the roller seat 3 is accurately installed. The combination of multiple plug-in structures better disperses the force on the roller seat 3, and when the shock-absorbing roller 4 vibrates, the vibration at a single position is reduced, reducing the risk of falling off. At the same time, the vibration transmission path is extended, the vibration wave is further attenuated, and resonance between adjacent roller seats 3 is avoided.

[0072] Example 5:

[0073] like Figure 3-Figure 7 As shown, based on the above embodiment 4, auxiliary mounting strips 19 are provided at the top and bottom ends of the side of the roller seat 3, the auxiliary mounting strips 19 abut against the side of the guide shoe bracket 2, and a rubber pad 20 is correspondingly provided on the guide shoe bracket 2.

[0074] The working principle and beneficial effects of the above technical solution are:

[0075] The two auxiliary mounting strips 19 on the side of the roller seat 3 contact the side of the guide shoe bracket 2 to improve the installation stability of the roller seat 3. The rubber pads 20 dampen the upper and lower sides of the roller seat 3 to reduce the collision between the roller seat 3 and the guide shoe bracket 2.

[0076] Example 6:

[0077] Based on the above-mentioned embodiment 1, the vibration monitoring unit includes a three-axis acceleration sensor or three unidirectional sensors, which are used to detect acceleration in the three coordinate axis directions of X, Y, and Z on the linkage part 14. The X-axis direction is the length direction of the elevator, the Y-axis direction is the width direction of the elevator, and the Z-axis direction is the height direction of the elevator. The controller integrates the three acceleration detection results and calculates the vibration amplitude of the linkage part 14. When the vibration amplitude exceeds the preset value, the controller activates the alarm unit to prompt the user to perform maintenance.

[0078] The working principle and beneficial effects of the above technical solution are:

[0079] The vibration detection unit is set in the linkage part 14. On the one hand, it can directly detect the vibration transmitted from the roller seat 3 to the linkage part 14 to evaluate the shock-absorbing effect of the shock-absorbing roller 4; on the other hand, the vibration of the linkage part 14 directly affects the installation stability of the roller seat 3, thereby evaluating the impact of the vibration on the installation status of the roller seat 3. During vibration monitoring, an acceleration sensor is used as a detection device to collect acceleration data in the directions of the three coordinate axes X, Y, and Z. The acceleration data in each direction is integrated to calculate the vibration amplitude of the linkage part 14 and use it as the basis for evaluation. When the vibration amplitude exceeds the preset value, it indicates that the vibration transmitted from the shock-absorbing roller 4 to the linkage part 14 is too large. The controller activates the alarm unit to prompt the user to inspect and maintain the shock-absorbing roller 4 and the roller seat 3.

[0080] Example 7:

[0081] like Figure 3-Figure 7 As shown, based on the above embodiment 4, a lubrication unit is provided inside the guide shoe bracket 2, and the lubrication unit includes:

[0082] A lubricating oil tank 21 is slidably connected to an oil tank groove 22 on the inner side of the guide shoe bracket 2;

[0083] Lubricating plates 23, two lubricating plates 23 are connected to the lubricating oil tank 21, and the lubricating plates 23 are arranged between adjacent shock-absorbing rollers 4. Lubricating brushes are provided on the lubricating plates 23, and a channel connecting the oil tank groove 22 and the lubricating brushes is provided on the lubricating plates 23, and the lubricating brushes are in contact with the guide rail.

[0084] The working principle and beneficial effects of the above technical solution are:

[0085] A lubrication unit is provided on the inner side of the guide shoe bracket 2, with a lubricating oil tank 21 integrated into the guide shoe bracket 2. Two lubricating plates 23 are positioned between adjacent damping rollers 4. Lubricating oil in the lubricating oil tank 21 enters the lubricating plates 23 and is evenly applied to the guide rail by a lubricating brush, thereby achieving lubrication even when the guide rail contacts the damping roller 4. The above structural design integrates the lubricating oil tank 21 into the guide shoe bracket 2, achieving a self-lubricating effect. Compared to elevators carrying lubricating oil tanks, the method of supplying lubricating oil to the guide rails through long pipelines reduces the elevator load, effectively avoids interference between the pipelines and the roller guide shoes, and improves elevator operation safety.

[0086] Example 8:

[0087] like Figure 3-Figure 7As shown, based on the above-mentioned embodiment 7, the lubrication unit further includes: an oil tank adsorption plate 24, which is slidably connected to the oil tank groove 22 and is arranged near the transmission groove 15. The side of the oil tank adsorption plate 24 away from the lubricating oil tank 21 is connected to the guide shoe bracket 2 via a spring, and the oil tank adsorption plate 24 has a tendency to move toward the roller seat 3;

[0088] The fuel tank adsorption plate 24 includes:

[0089] The second chute 25 is provided on a side of the oil tank adsorption plate 24 close to the transmission groove 15;

[0090] A wedge block 26 is slidably connected to the second chute 25 and is disposed near the end of the linkage member 14;

[0091] The air collecting chamber 27 is provided at the center of the oil tank adsorption plate 24;

[0092] Negative pressure adsorption holes 28 , multiple negative pressure adsorption holes 28 are provided on one side of the oil tank adsorption plate 24 close to the lubricating oil tank 21 , and the negative pressure adsorption holes 28 are communicated with the gas collecting cavity 27 ;

[0093] A suction chamber 29 is provided in the oil tank adsorption plate 24 and communicates with the gas collecting chamber 27 . The suction chamber 29 is arranged close to the second chute 25 .

[0094] The piston 31 is slidably connected to the suction chamber 29, and a spring is connected between one side of the piston 31 and the suction chamber 29, and the space on the other side of the piston 31 is connected to the gas collecting chamber 27;

[0095] The pressure rod 32 is connected to the other end of the piston 31 and extends into the second sliding groove 25. The end of the pressure rod 32 is slidably connected to the wedge surface of the wedge block 26.

[0096] The working principle and beneficial effects of the above technical solution are:

[0097] The roller seat 3 is installed to install the lubricating oil tank 21. When the roller seat 3 is installed and the lubricating oil tank 21 is not installed, the linkage part 14 squeezes the wedge block 26. Since the elastic force of the spring on the side of the oil tank adsorption plate 24 is less than the elastic force of the spring on the piston 31, the wedge block 26 pushes the oil tank adsorption plate 24 to move, so that it remains away from the transmission groove 15; when the lubricating oil tank 21 is installed, the lubricating oil tank 21 is squeezed into the oil tank groove 22, the lubricating oil tank 21 contacts the oil tank adsorption plate 24, and pushes the oil tank adsorption plate 24 to move in the direction of the transmission groove 15. Since the linkage part 14 remains stationary, the wedge block 26 moves in the second slide groove 25, the wedge surface of the wedge block 26 slides relative to the pressure rod 32, and then squeezes the pressure rod 32 to move into the suction chamber 20, pushing the piston 31 to move to the side of the suction chamber 29, so that the suction chamber 29 is connected to the air collecting chamber 27. Negative pressure is generated, the air in the air collecting chamber 27 is sucked, and negative pressure is generated at the negative pressure adsorption hole 28, which firmly adsorbs the lubricating oil tank 21.

[0098] Through the above-mentioned structural design, when the lubricating oil tank 21 is installed, the lubricating oil tank 21 can be stably installed in the oil tank groove 22 by adsorption, so as to prevent the lubricating brush from being subjected to force and causing the lubricating oil tank 21 to shake during the lubrication process; the lubricating oil tank 21 is prevented from protruding from the inner wall of the guide shoe bracket 2, so as to prevent the lubricating oil tank 21 from colliding with the guide rail; at the same time, after the lubricating oil tank 21 is stably installed, the wedge block 26 and the oil tank adsorption plate 24 can abut against the end of the linkage part 14, further realizing the limitation of the linkage part 14; the roller seat 3 and the lubricating oil tank 21 are integrated on the guide shoe bracket 2 at the same time, the lubricating oil delivery distance is short, the loss during the lubricating oil delivery process is reduced, and the installation position of the lubricating plate 23 is ensured to be accurate, and the lubricating brush can fully contact the guide rail.

[0099] Example 9:

[0100] like Figure 3-Figure 7 As shown, on the basis of the above-mentioned embodiment 8, a limit rod 33 is inserted into the lubricating oil tank 21, and the end of the limit rod 33 is flush with the inner wall of the lubricating oil tank 21 and the guide shoe bracket 2. The rod portion of the limit rod 33 is inserted into the guide shoe bracket 2, and a limit groove 34 is provided on the side wall of the limit rod 33; a third slide groove 35 is correspondingly provided on the guide shoe bracket 2, and a card block 36 is connected to the third slide groove 35 through a spring, and the card block 36 is magnetic, and the card block 36 is inserted into the limit groove 34; a magnetic block 37 is connected to the side wall of the lubricating oil tank 21, and the magnetic block 37 and the card block 36 are staggered when the lubricating oil tank 21 is installed.

[0101] The working principle and beneficial effects of the above technical solution are:

[0102] After the oil tank adsorption plate 24 adsorbs the lubricating oil tank 21, the limit rod 33 is inserted into the lubricating oil tank 21, and its end is inserted into the guide shoe bracket 2; after the limit groove 34 on the limit rod 33 corresponds to the third slide groove 35, the magnetic block 37 and the clamping block 36 are staggered, and the clamping block 36 pops out under the action of the spring 37 and engages with the limit groove 34 to lock the position of the limit rod 33, thereby realizing the limitation of the lubricating oil tank 21 in the width direction of the guide shoe bracket 2; the lubricating oil tank 21 is accurately positioned so that the end of the limit rod 33 is flush with the inner wall of the lubricating oil tank 21 and the guide shoe bracket 2, ensuring the flatness of the installation position of the lubricating oil tank 21 and reducing the collision between the lubricating oil tank 21 and the guide rail.

[0103] When the roller seat 3 is removed, the linkage part 14 rotates and resets, and the wedge block 26 resets under the action of the spring, so that the negative pressure at the negative pressure adsorption hole 28 disappears, and the suction force on the lubricating oil tank 21 is lost; at the same time, the oil tank adsorption plate 24 moves toward the transmission groove 15 under the action of the spring, so that the magnetic block 37 and the card block 36 are close to each other, and the magnetic block 37 attracts the card block 36 to move it out of the limiting groove 34, thereby releasing the limit on the limiting rod 33, and the lubricating oil tank 21 can be moved out.

[0104] Through the above-mentioned structural design, when the shock-absorbing roller 4 on one side has serious overload friction or shock absorption failure and needs to be repaired, the lubricating oil tank 21 can be removed synchronously when the roller seat 3 on this side is quickly disassembled, and the lubricating oil tank 21 can be replenished, cleaned, repaired and other maintenance operations. This can adapt to the problem of increased lubricating oil volume caused by increased contact area between the lubricating brush and the track in the case of severe overload, so that it is adapted to the maintenance node of the shock-absorbing roller 4, and the elevator maintenance effect is better.
