Description

Technical Field

[0001] This utility model relates to the field of elevator guide shoes, and in particular to a guide shoe structure. Background Technology

[0002] Elevators, as an important means of transportation for vertically transporting people and goods, have become fully integrated into people's lives. With rapid socio-economic development, people are placing increasingly stringent demands on elevator safety, comfort, and speed. Existing elevator guide shoes, divided into sliding guide shoes and rolling guide shoes, are key guiding components in elevators, lifts, and other equipment, primarily used to guide the elevator car or counterweight smoothly along the guide rails.

[0003] For medium- and low-speed elevators, sliding guide shoes are a more common choice. Sliding guide shoes have a simple structure, low cost, and can meet the operational requirements of medium- and low-speed elevators. They achieve their guiding function through the sliding contact between the shoe liner and the guide rail. Prior art document CN211198276U provides an elevator sliding guide shoe, including a shoe base, a shoe liner, and a locking and positioning part; the shoe base has a first mounting groove with an upward opening at its center; the shoe liner has a second mounting groove with an upward opening at its center; the shoe liner is locked into the first mounting groove by the locking and positioning part; the first mounting groove and the second mounting groove are arranged parallel to each other; a reinforcing plate is fixedly installed inside the shoe liner. The shoe base, shoe liner, and locking positioning part are detachable, facilitating the replacement and maintenance of each component; the use of bolts, nuts, and other fixing connectors is eliminated, reducing the difficulty of manufacturing, processing, and assembly; and the fewer components also improve the overall structural integrity and strength of the sliding guide shoe, thereby extending its service life; the reinforcing plate inside the shoe liner significantly improves the overall strength of the shoe liner, enhancing the stability and reliability of the sliding guide shoe during operation, and extending the service life of the shoe liner, thereby further reducing the company's production and manufacturing costs.

[0004] In the aforementioned comparative documents, although the guide shoes are designed with trapezoidal guide plates and oil reservoirs, when the oil level is low, they cannot lubricate the guide shoes and guide rails for extended periods. This results in significant friction after prolonged sliding within the guide rails, leading to faster wear and frequent replacement of the guide shoes, increasing maintenance and downtime costs. Furthermore, the aforementioned documents describe a process where the shoe liner is disassembled by forcefully squeezing both sides to engage the protrusions with corresponding grooves, thus completing the assembly. However, forcefully squeezing the shoe liner during installation can deform it, making subsequent installation on the guide rails difficult and inconvenient. To address these issues, a solution is proposed below. Utility Model Content

[0005] The purpose of this invention is to provide a guide shoe structure to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A guide shoe structure includes a shoe base, a shoe liner, a locking and positioning part, and an oil cup. The shoe base has a mounting groove in the middle, the locking and positioning part is disposed in the mounting groove, the shoe liner is connected to the mounting groove through the locking and positioning part, and the oil cup is fixed to the top of the shoe base by bolts.

[0008] The engaging positioning part includes multiple positioning blocks and two connecting springs. Each positioning block is respectively installed on the bottom surface and two side surfaces of the mounting groove. The positioning blocks on the two side surfaces are staggered. The boot liner has multiple slots corresponding to each positioning block. Two wide slots are respectively opened on the two side walls of the mounting groove. The two positioning blocks are slidably disposed in the two wide slots. The two connecting springs are respectively installed in the two wide slots. One end of the connecting spring is fixedly connected to the wide slot, and the other end of the connecting spring is fixedly connected to the positioning block.

[0009] Preferably, the boot liner has an inner groove in the middle that is adapted to the guide rail, and each of the slots communicates with the inner groove. The two ends of the inner groove are respectively the inlet and the outlet, and the two sides of the inlet and the outlet are inclined to both sides respectively.

[0010] Preferably, the top and bottom of the boot seat are fixed with limit baffles, and the two limit baffles correspond to the inlet and outlet of the boot liner, respectively.

[0011] Preferably, a rubber shock-absorbing pad adapted to the mounting groove is also installed in the mounting groove. The bottom of the boot liner is in contact with the rubber shock-absorbing pad. The rubber shock-absorbing pad has a second slot corresponding to each of the positioning blocks. One end of the positioning block passes through the second slot and is set in the first slot.

[0012] Preferably, the boot base is further provided with two grooves, which are located on both sides of the mounting groove.

[0013] Preferably, the boot base is also fixed with multiple reinforcing plates.

[0014] Beneficial effects: This application installs an oil cup on the top of the shoe seat, allowing lubricating oil to flow into the shoe liner. The inclined inlet on the top of the shoe liner facilitates the flow of lubricating oil between the guide rail and the shoe liner, thus facilitating lubrication of both. The oil cup design ensures a continuous and stable supply of oil to the shoe liner, reducing the coefficient of friction and further reducing operating resistance and wear. By designing the positioning blocks on both sides of the mounting groove as sliding connections, it is possible to install and remove the shoe liner without squeezing and deforming it during disassembly and installation. The positioning blocks can be moved into the slots by pressing the positioning blocks on both sides, making the installation and removal of the shoe liner more convenient.

[0022] See Figures 1 to 6 As shown, a guide shoe structure includes a shoe base 1, a shoe liner 2, a locking and positioning part 3, and an oil cup 4. The shoe base 1 has an installation groove 5 in the middle, the locking and positioning part 3 is disposed in the installation groove 5, and the shoe liner 2 is connected to the installation groove 5 through the locking and positioning part 3.

[0023] The boot liner 2 has an inner groove 10 in the middle. The boot liner 2 achieves sliding contact with the guide rail through the inner groove. The two ends of the inner groove 10 are respectively the inlet 11 and the outlet 12. The two sides of the inlet 11 and the outlet 12 are inclined to the sides respectively. The inlet liner 2 is more convenient to assemble with the boot seat 1 through the inlet 11 and the outlet 12 designed at both ends.

[0024] Limiting baffles 13 are fixed at the top and bottom of the boot base 1. The two limiting baffles 13 correspond to the inlet 11 and outlet 12 of the boot liner 2, respectively. By installing the limiting baffles 13 on both the upper and lower sides of the boot base 1, the boot liner 2 can be limited in its installation, preventing the boot liner 2 from being dislodged from the installation groove 5 due to excessive force during use.

[0025] The oil cup 4 is fixed to the top of the shoe seat 1 by bolts. The oil outlet of the oil cup 4 corresponds to the inlet 11 of the shoe liner 2, so that the lubricating oil in the oil cup 4 can flow into the shoe liner 2. Through the inclined inlet 11 designed on the top of the shoe liner 2, the lubricating oil can flow between the guide rail and the shoe liner 2, thereby facilitating the lubrication of the shoe liner 2 and the guide rail.

[0026] The locking and positioning part 3 includes multiple positioning blocks 6 and two connecting springs 7. Each positioning block 6 is installed on the bottom and side surfaces of the mounting groove 5, and the positioning blocks 6 on the two sides are staggered. The boot liner 2 has multiple slots 8 corresponding to each positioning block 6. Two wide slots 9 are respectively opened on the side walls of the mounting groove 5. The two positioning blocks 6 are slidably disposed in the two wide slots 9. The two connecting springs 7 are respectively installed in the two wide slots 9. One end of the connecting spring 7 is fixedly connected to the wide slot 9, and the other end of the connecting spring 7 is fixedly connected to the positioning block 6. When the boot liner 2 needs to be installed, the positioning blocks 6 on both sides of the mounting groove 5 are squeezed, causing the positioning blocks 6 to slide into the wide slots 9. During the movement, the positioning blocks 6 will squeeze the connecting springs 7. Spring 7 generates elastic force. After positioning block 6 enters the wide groove 9, it does not limit the movement of boot liner 2. Manually, boot liner 2 can be slid into the mounting groove 5. During the sliding process, boot liner 2 will block the wide groove 9. At this time, positioning block 6 can be released. Positioning block 6 is squeezed by boot liner 2. When boot liner 2 moves to the designated position, the slot 8 on boot liner 2 will correspond to positioning block 6. At this time, the elastic force of connecting spring 7 will be released. Through the release of the elastic force of connecting spring 7, one end of positioning block 6 enters into slot 8. Positioning block 6 can play the role of positioning and installing boot liner 2. When boot liner 2 needs to be replaced later, positioning block 6 can also be squeezed again to make positioning block 6 enter the wide groove 9, thereby realizing the removal of boot liner 2.

[0027] A rubber shock-absorbing pad 14 adapted to the mounting groove 5 is also installed in the mounting groove 5. The bottom of the boot liner 2 contacts the rubber shock-absorbing pad 14. The rubber shock-absorbing pad 14 has a slot 2 corresponding to each positioning block 6. One end of the positioning block 6 passes through the slot 2 and is set in the slot 8. By installing the rubber shock-absorbing pad 14 between the boot liner 2 and the boot seat 1, the boot liner 2 can be better installed, and the vibration and noise generated by the boot liner 2 during use can be reduced.

[0028] The boot base 1 is also provided with two grooves 15, which are located on both sides of the mounting groove 5. The design of the two grooves 15 makes it easy to take out the boot liner 2 and remove it from the mounting groove 5.

[0029] Multiple reinforcing plates 16 are also fixed on the boot base 1. By designing multiple reinforcing plates 16 on the boot base 1, the strength of the boot base 1 can be improved.
