A wear-resistant sheath for elevator cables

Abstract

This utility model discloses an anti-wear sheath for elevator cables, relating to the field of cable protection technology. The utility model includes a first sheath and a second sheath at its bottom. A splicing mechanism is provided inside the first sheath. By incorporating a compression spring, the cable is first placed between the first and second sheaths. Then, the two side locking blocks at the bottom of the first sheath are inserted into the locking grooves of the connecting block. The bottom of the locking block presses against the insert rods inside the connecting blocks, causing the insert rods to move outwards along with the sliding rings. Simultaneously, the insert rods slide within the connecting block. When the locking block is inserted into the bottom of the locking groove, the slot and the insert rod are on the same horizontal plane. The compression springs on both sides then compress the sliding rings and reset them. The insert rods then insert into the locking block, completing the splicing of the first and second sheaths, thus simplifying and effectively implementing the installation process.

Description

Technical Field

[0001] This utility model belongs to the field of cable protection sleeve technology, and in particular relates to an anti-wear sleeve for elevator cables. Background Technology

[0002] With the increasing number of high-rise buildings and the continuous development of elevator technology, the operating speed and load capacity of elevators are constantly improving, which places higher and higher demands on the performance of cables. For example, in high-speed elevators, the wear problem of cables is more prominent, requiring the use of more wear-resistant and flexible sheath materials and more reasonable structural designs to ensure that cables can stably and reliably transmit power and signals during long-term operation.

[0003] When installing elevator cable sheaths, the process is complicated because the sheath is a single unit. Multiple cables need to be threaded through the sheath, and each cable must be arranged neatly and without interference. To address this, we provide an anti-wear sheath for elevator cables. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-wear sheath for elevator cables. By placing sheath one and sheath two on both sides of multiple cables, and then inserting the snap-fit ​​block one of sheath one into the bottom of the snap-fit ​​groove one, the plug rod will be inserted into the slot one, thereby completing the quick fixation and solving the problem of complicated installation of existing sheaths.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an anti-wear sheath for elevator cables, including a sheath one, a sheath two at the bottom of the sheath one, a splicing mechanism inside the sheath one, a sheath three on the outer wall of the sheath one, and a connecting and fixing mechanism on the outer wall of the sheath one.

[0007] The splicing mechanism includes a snap-fit ​​block 1, the top of which is fixedly connected to the bottom of the sheath 1, and a slot 1 is provided inside the snap-fit ​​block 1. A connecting block is fixedly connected to the top of the sheath 2, and a snap-fit ​​groove 1 is provided inside the connecting block. An insert rod is slidably connected to the inner wall of the connecting block, and a sliding ring is fixedly connected to the outer surface of the insert rod. A compression spring is fixedly connected to the inner wall of the sliding ring, and the end of the outer wall of the compression spring away from the sliding ring is fixedly connected to the inner wall of the connecting block.

[0008] Furthermore, the outer surface of the snap-fit ​​block snaps into the inner wall of the snap-fit ​​groove, the outer surface of the sliding ring slides into the inner wall of the connecting block, and the outer surface of the insertion rod slides into the inner wall of the slot.

[0009] Furthermore, the connecting and fixing mechanism includes a second snap-fit ​​block, the inner wall of which is fixedly connected to the outer wall of the third sheath.

[0010] Furthermore, the inner wall of the sheath is provided with slot 2, and there are four slot 2 in total. The inside of the sheath is provided with snap-fit ​​groove 2.

[0011] Furthermore, there are two snap-fit ​​slots, and the inner walls of both snap-fit ​​slots are snapped into the outer surface of the snap-fit ​​block. The snap-fit ​​block has a slot three inside.

[0012] Furthermore, both slot 2 and slot 3 have locking blocks on their inner walls, and there are a total of four locking blocks. The inner wall of each locking block is fixedly connected to a fixing ring, and the outer surface of the fixing ring is rotatably connected to a fitting block.

[0013] Furthermore, a rotating block is rotatably connected to the outer surface of the second slot, a pressing plate is fixedly connected to the outer wall of the rotating block, and a screw is threadedly connected to the inner wall of the fitting block.

[0014] Furthermore, the outer surface of the screw is threadedly connected to the inner wall of the pressing plate, and a connecting rod is rotatably connected to the outer surface of the rotating block. The end of the inner wall of the connecting rod away from the rotating block is rotatably connected to the outer surface of the fixing ring.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a compression spring, allows the cable to be placed between sheath one and sheath two. Then, the two snap-fit ​​blocks at the bottom of sheath one are inserted into the snap-fit ​​grooves of the connecting block. The bottom of snap-fit ​​block one will then press the insert rod inside the connecting block on both sides. The insert rod will then drive the sliding ring to move outward. At the same time, the insert rod will slide inside the connecting block. When snap-fit ​​block one is inserted into the bottom of snap-fit ​​groove one, the slot one inside snap-fit ​​block one and the insert rod will be on the same horizontal plane. At this time, the compression spring on both sides will press the sliding ring and drive it to reset. Then the insert rod will be inserted into snap-fit ​​block one, thus completing the splicing of sheath one and sheath two. This makes the installation process simple and effective, ensures the stability of the sheath and avoids cable wear during use, and also has good pressure resistance and durability.

[0017] 2. This utility model uses a pull rod to insert the snap-fit ​​blocks 2 on both sides of the outer side of the third sheath into the snap-fit ​​grooves 2 of the first and second sheaths. When the snap-fit ​​blocks 2 are fully inserted into the snap-fit ​​grooves 2, the slots 3 at the top and bottom of the third sheath will overlap with the slots 2 inside the first and second sheaths. Then, a retaining ring can be fitted onto the surface of the third sheath, and the retaining ring and the snap-fit ​​blocks inside the fitting block can be inserted into the inner walls of slots 2 and 3 respectively. Then, the pressing plate is pressed towards the fitting block. At this time, the pressing plate will drive the rotating block to rotate on the surface of the fitting block, simultaneously connecting... The rod rotates on the outer surface of the rotating block, which then pulls the connecting rod. Simultaneously, the connecting rod rotates on the surface of the fixed ring. When the pressing plate and the bonding block are in contact, the equipment firmly fixes the connection between sheath one and sheath two and sheath three. This process is repeated to complete the installation of the cable outer shell, ensuring that the connection points of each sheath are tightly joined and firmly fixed, ensuring the stability and safety of the sheath connection points, preventing the sheaths from loosening or falling off during use, and effectively protecting the cable from external wear and damage.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model is an anti-wear sheath for elevator cables, including a sheath 3, a sheath 4 at the bottom of the sheath 3, a splicing mechanism 1 inside the sheath 3, a sheath 5 on the outer wall of the sheath 3, and a connecting and fixing mechanism 2 on the outer wall of the sheath 3.

[0029] The splicing mechanism 1 includes a snap-fit ​​block 101. During the splicing and installation of the first sheath 3 and the second sheath 4, the snap-fit ​​block 101 is inserted into the snap-fit ​​groove 104 to achieve initial positioning and fixation. The top of the snap-fit ​​block 101 is fixedly connected to the bottom of the first sheath 3. A slot 103 is provided inside the snap-fit ​​block 101, through which the insertion rod 105 can be inserted, thereby fixing the connecting block 102 inside the snap-fit ​​groove 104. The top of the second sheath 4 is fixedly connected to the connecting block 102. An internal snap-fit ​​groove 104 is provided. A plug rod 105 is slidably connected to the inner wall of the connecting block 102. When the plug rod 105 is inserted into the slot 103, the plug rods 105 on both sides will secure the slot 103, thereby fixing the snap-fit ​​block 101 and further securing it, thus firmly fixing the sheath 3 and sheath 4. A sliding ring 107 is fixedly connected to the outer surface of the plug rod 105. Pulling the plug rod 105 outwards will cause the sliding ring 107 to move outwards, thereby compressing the compression spring 106, thus allowing the plug rod 105 to... 5. Disconnect from inside slot 103, thus completing the disassembly of sleeve 3 and sleeve 4. A compression spring 106 is fixedly connected to the inner wall of sliding ring 107. When connecting block 102 is inserted into slot 104, the bottom of connecting block 102 will press against the top of insert rod 105, causing insert rod 105 to move sliding ring 107 and compression spring 106 outward. When connecting block 102 is fully inserted into the bottom of slot 104, slot 103 will be at the same level as insert rod 105, and then compression spring 106 will move outward. The movable insertion rod 105 is reset, thereby driving the insertion rod 105 to be inserted into the slot 103, thus completing the splicing and fixing of the sheath 3 and the sheath 4. The end of the outer wall of the compression spring 106 away from the sliding ring 107 is fixedly connected to the inner wall of the connecting block 102. The outer surface of the snap-fit ​​block 101 is snapped into the inner wall of the snap-fit ​​groove 104. The outer surface of the sliding ring 107 is slidably connected to the inner wall of the connecting block 102. The outer surface of the insertion rod 105 is slidably connected to the inner wall of the slot 103. The connecting and fixing mechanism 2 includes a snap-fit ​​block 204. The inner wall of the snap-fit ​​block 204 is fixedly connected to the outer wall of the sheath 3 5.

[0030] The inner wall of the sheath 1 3 has four slots 201. The sheath 1 3 also has two snap-fit ​​grooves 203. When the snap-fit ​​block 204 is inserted into the snap-fit ​​groove 203, the snap-fit ​​block 204 will engage with the snap-fit ​​groove 203. Simultaneously, multiple slots 3 202 overlap with slots 201. There are two snap-fit ​​grooves 203, and the inner walls of both slots 203 engage with the outer surface of the snap-fit ​​block 204. The snap-fit ​​block 204 has three slots 202 inside, which allow for the engagement of the sheath 1 3 with the snap-fit ​​block 204. When reinforcing the connection between sleeve 3 5 and sleeve 1 3, the retaining ring 205 and the locking block 206 on the inner wall of the fitting block 210 can be inserted into the slots 201 on both sides respectively, thereby strengthening the connection between sleeve 1 3 and sleeve 3 5. The inner walls of slot 201 and slot 3 202 are both fitted with locking blocks 206. The locking blocks 206 can be inserted into the slots 201 on the surface of sleeve 1 3 and sleeve 3 5. There are four locking blocks 206 in total. The retaining ring 205 is fixedly connected to the inner wall of the locking block 206, and the fitting block 210 is rotatably connected to the outer surface of the retaining ring 205.

[0031] A rotating block 208 is rotatably connected to the outer surface of slot 201. When the rotating block 208 rotates, it can drive the connecting rod 207 to move in the direction of the rotating block 208. A pressing plate 211 is fixedly connected to the outer wall of the rotating block 208. By pressing the pressing plate 211 in the direction of the mating block 210, the rotating block 208 can be driven to rotate on the surface of the mating block 210, thereby causing the rotating block 208 to rotate and tilt in the direction of the mating block 210, which in turn pulls the connecting rod 207 to tighten the fixing ring 205, thereby connecting the first sheath 3 and the third sheath 5. The connection is effectively reinforced. The inner wall of the bonding block 210 is threaded with screws 209. When the pressing plate 211 is attached to the surface of the bonding block 210, the screws 209 can be screwed into the interior of the bonding block 210 and the pressing plate 211 to fix the pressing plate 211, thereby making the connection of the equipment more secure. The outer surface of the screws 209 is threaded to the inner wall of the pressing plate 211. The outer surface of the rotating block 208 is rotatably connected to the connecting rod 207. The end of the inner wall of the connecting rod 207 away from the rotating block 208 is rotatably connected to the outer surface of the fixing ring 205.

[0032] One specific application of this embodiment is:

[0033] When installing abrasion-resistant sheaths on cables, first place the cable between sheath 3 and sheath 4. Then, insert the two snap-fit ​​blocks 101 at the bottom of sheath 3 into the snap-fit ​​grooves 104 of the connecting block 102. The bottom of the snap-fit ​​blocks 101 will then press against the insert rods 105 inside the connecting blocks 102. The insert rods 105 will then drive the sliding ring 107 to move outward, while the sliding ring 107 will compress the spring 106. Simultaneously, the insert rods 105 will slide inside the connecting block 102. When the snap-fit ​​block 101 is inserted into the bottom of the snap-fit ​​slot 104, the slot 103 and the plug rod 105 inside the snap-fit ​​block 101 will be on the same horizontal plane. At this time, the compression springs 106 on both sides will squeeze the sliding ring 107 and drive it to reset. Then the plug rod 105 will be inserted into the snap-fit ​​block 101, thereby completing the splicing of the sheath 3 and the sheath 4. This makes the installation process simple and effective, ensures the stability of the sheath and avoids cable wear during use, and also has good pressure resistance and durability.

[0034] After the wear-resistant sleeve is installed, the two sleeves 3 5 can be spliced ​​together in the above manner. Then, insert the snap-fit ​​blocks 204 on both sides of the outer side of sleeve 3 5 into the snap-fit ​​grooves 203 of sleeve 1 3 and sleeve 2 4. When the snap-fit ​​blocks 204 are inserted to the innermost part of the snap-fit ​​grooves 203, the slots 3 202 at the top and bottom of sleeve 3 5 will coincide with the slots 201 inside sleeve 1 3 and sleeve 2 4. Then, the retaining ring 205 can be put onto the surface of sleeve 3 5, and the retaining ring 205 and the snap-fit ​​blocks 206 inside the fitting block 210 can be inserted into the inner walls of slots 201 and 302 respectively. Then, press the pressing plate 211 towards the fitting block 210. At this time, the pressing plate 211... The rotating block 208 will rotate on the surface of the bonding block 210, while the connecting rod 207 will rotate on the outer surface of the rotating block 208. Then the rotating block 208 will pull the connecting rod 207, and the connecting rod 207 will also rotate on the surface of the fixing ring 205. At this time, when the pressing plate 211 is bonded to the bonding block 210, the equipment will firmly fix the connection between the first sheath 3 and the second sheath 4 and the third sheath 5. This process is repeated to complete the installation of the cable shell, thereby ensuring that the connection of each sheath is tightly connected and firmly fixed, ensuring the stability and safety of the sheath connection, preventing the sheath from loosening or falling off during use, and effectively protecting the cable from external wear and damage.
